Also, the plurality of guide posts 1222b may ensure that the bracket 1222 is maintained to move in a vertical direction during the ascending or descending process, thereby preventing a seizure phenomenon. As can be seen in fig. 3, the bracket 1222 further includes a cup holder 1222c mounted on the bottom plate 1222a, and the cup holder 1222c is provided with a circular receiving hole penetrating vertically. With continued reference to fig. 8, the powder container 123 is cylindrical cup-shaped and includes a cylindrical cup body 1231, and a locking ring 1233 is protruded on the outer peripheral side of the cup body 1231. Here, the outer diameter of the cup body 1231 is smaller than the inner diameter of the receiving hole, and the outer diameter of the locking protrusion ring 1233 is larger than the inner diameter of the receiving hole, so that the cup body 1231 of the powder container 123 is inserted into the receiving hole while the locking protrusion ring 1233 is supported by the cup holder 1222 c. It will be appreciated that, when the transport vehicle 122 carries the powder container 123 to the weighing position, the powder container 123 is now located just above the weighing module 13 with a first distance to the weighing module 13, and, at this time, when the carriage 1222 is lowered by the first cylinder 1223, the powder container 123 is lowered together with the carriage, when the carriage 1222 is lowered by a distance greater than the first distance, the powder container 123 may be caused to rest on the weighing module 13, while the powder container 123 is separated from the bracket 1222 and loses the supporting force given by the bracket 1222, falls from the powder container 123 onto the weighing module 13 by its own weight, when the powder container 123 is supported on the weighing module 13, the powder container 123 is in the receiving hole and does not contact the bracket 1222.

In summary, the process of adding a fixed amount of powder to one powder container 123 is as follows: the transport vehicle 122 carries the powder container 123 to the powder adding position, and at this time, the output motor operates to make the powder in the feeding module 11 fall into the powder container 123 from the discharging pipe; then the transport vehicle 122 carries the powder container 123 with powder therein to the weighing position, the powder container 123 with powder therein is located right above the weighing module 13, the first cylinder 1223 drives the bracket 1222 to descend so that the powder container 123 falls down onto the weighing module 13, and the weighing module 13 performs a first weighing when the powder container 123 is supported on the weighing module 13; after the first weighing, the first cylinder 1223 drives the bracket 1222 to ascend so that the powder container 123 with powder therein is separated from the weighing module 13, the bracket 1222 re-lifts and supports the powder container 123, and then the transport vehicle 122 carries the next empty powder container 123 to the powder adding position, so as to complete the quantitative powder adding to one powder container 123. It should be appreciated that repeating the above process may add a metered amount of powder to a plurality of powder containers 123 on the transport vehicle 122.

Referring to fig. 5, the feeding unit 22 includes a first sliding seat 221 movably mounted on the third guide rail 21, an eighth driving unit 224 mounted on the first sliding seat 221, a fourth guide rail 225 laid on the first sliding seat 221 and having an extending direction identical to that of the third guide rail 21, a second sliding seat connected to the eighth driving unit 224 and movably mounted on the fourth guide rail 225, a sixth driving unit 222 mounted on the second sliding seat, and a gripper 223 connected to the sixth driving unit 222. Here, the fifth driving unit 23 includes a fifth lead screw 231 inserted into the first sliding seat 221 and screwed with the first sliding seat 221, and a fifth motor 232 connected to the fifth lead screw 231, and an extending direction of the fifth lead screw 231 is identical to an extending direction of the third guide rail 21. In this way, the fifth motor 232 can drive the first sliding seat 221 to move linearly along the third guide rail 21. The sixth driving unit 222 includes a sixth motor 2221 and a sixth gear set (not shown) including a sixth driving gear (not shown) coaxially connected to an output shaft of the sixth motor 2221 and a sixth driven gear (not shown) connected to the holder 223, the holder 223 and the sixth driven gear are connected by a link having one end fixed to the holder 223 and the other end coaxially connected to the sixth driven gear, and the sixth driving gear and the sixth driven gear are connected by a sixth chain, so that the holder 223 can be driven by the sixth motor 2221 to turn 180 °. Here, the eighth driving unit 224 includes an eighth screw rod 2241 inserted into the second sliding seat and screwed with the second sliding seat, and an eighth motor 2242 connected with the eighth screw rod 2241, and an extending direction of the eighth screw rod 2241 coincides with an extending direction of the fourth guide rail 225. In this way, the eighth motor 2242 may drive the second sliding seat to move linearly along the fourth guide rail 225. It should be understood that the second sliding seat can move to bring the clamper 223 to move together synchronously.

Referring to fig. 5, as shown in fig. 5, the automatic blanking apparatus 200 further includes a feeding hopper 24 installed on the first sliding seat 221, a guide tube 25 movably disposed in an up-and-down manner and sleeved on a lower end of the feeding hopper 24, and a seventh driving unit 26 connected to the guide tube 25. Here, the seventh driving unit 26 includes a mounting panel 261, a seventh guide rail 262, a seventh slider (not shown), a seventh motor 264, a seventh lead screw 265, and a connecting arm 266. The mounting panel 261 is fixed on the first sliding seat 221, the seventh guide rail 262 is laid on the mounting panel 261 and extends in the vertical direction, the seventh slider is movably mounted on the seventh guide rail 262, the seventh lead screw 265 passes through the seventh slider and is in threaded connection with the seventh slider, the output shaft of the seventh motor 264 is coaxially connected with the seventh lead screw 265, one end of the connecting arm 266 is connected with the seventh slider, and the other end is connected with the guide tube 25. Here, one end of the connecting arm 266 is connected to the seventh slider, and the guide tube 25 is vertically inserted and fixed to the other end of the connecting arm 266. Therefore, when the seventh motor 264 operates, the seventh sliding block can be driven to move up and down, so as to drive the guide tube 25 to move up and down. It should be noted that when the holding furnace 400 is moved to above the toughening furnace 500, the powder container 123 at the position to be charged is located directly below the holder 223. Thus, it can be understood that when the transport vehicle 122 carries the powder container 123 to the position to be discharged, the first cylinder 1223 of the first driving unit can drive the carriage 1222 to ascend the powder container 123 into the two holding arms of the holder 223, at which time the two holding arms of the holder 223 are tightened to clamp the powder container 123, the first cylinder 1223 drives the carriage 1222 to descend after the holder 223 holds the powder container 123 to make the powder container 123 rise above the carriage 1222, then the eighth motor 2242 drives the second sliding seat to move to make the powder container 123 move to the position right above the discharging hopper 24, then the fifth motor 232 drives the first sliding seat 221 to move to make the powder container 123 and the discharging hopper 24 move to the charging position (of course, in order to improve the feeding efficiency, it may be designed that the feeding hopper 24 is already located at the feeding position at the initial state), at this time, the sixth motor 2221 of the feeding unit 22 may drive the holder 223 to turn 180 ° so that the opening of the powder container 123 faces downward when the powder container 123 reaches the feeding position, the powder in the powder container 123 is fed into the feeding hopper 24, then the sixth motor 2221 drives the holder 223 to turn 180 ° again so that the opening of the powder container 123 faces upward, the fifth motor 232 and the eighth motor 2242 respectively drive the first sliding seat 221 and the second sliding seat to move so as to return the powder container 123 to the initial position so that the powder container 123 is aligned with the containing hole on the bracket 1222, the holder 223 releases the powder container 123 so that the powder container 123 falls back into the containing hole, the first cylinder 1223 drives the carriage 1222 to descend so that the powder container 123 is completely removed from the holder 223, and thus the powder in the powder containers 123 on the carriage 1222 can be completely added into the strengthening furnace. On the other hand, before the sixth motor 2221 drives the gripper 223 to turn over by 180 °, the seventh motor 264 is operated in advance to drive the guide tube 25 to move downward to extend above the liquid level in the toughening furnace 500, so as to ensure that all the powder in the powder container 123 flows into the toughening furnace 500. With continued reference to fig. 5, vibration motors 27 are further installed on two sides of the discharging hopper 24, and during discharging, the vibration motors 27 operate to drive the discharging hopper 24 and the guide tube 25 to vibrate, so that the powder adhered to the inner walls of the discharging hopper 24 and the guide tube 25 is vibrated down and falls into the toughening furnace 500, and the accuracy of quantitative addition is ensured.

It should be noted that the automatic powder quantitative supply device 100 includes four powder containers 123, the bracket 1222 is provided with four receiving holes, and the four powder containers 123 are respectively placed in the four receiving holes, that is, the bracket 1222 can deliver four powder containers 123 at a time. Thus, when one toughening furnace 500 is automatically charged, powder can be added at four opposite corners of the toughening furnace 500 respectively. The specific process is as follows: the holding furnace 400 is moved to above the toughening furnace 500 so that the discharging hopper 24 is aligned with a diagonal of the front side of the toughening furnace 500, the transport vehicle 122 first moves the first powder container 123 to just below the holder 223, the charging unit 22 pours the powder in the first powder container 123 into a diagonal of the front side of the toughening furnace 500 and returns the first powder container 123 to the transport vehicle 122, then the transport vehicle 122 moves the second powder container 123 to just below the holder 223, then the charging unit 22 pours the powder in the second powder container 123 into the other diagonal of the front side of the toughening furnace 500 and returns the second powder container 123 to the transport vehicle 122, and then the holding furnace 400 continues to move so that the discharging hopper is aligned with a diagonal of the rear side of the toughening furnace 500, the transport cart 122 then moves the third powder container 123 to a position right under the holder 223, the feeding unit 22 pours the powder in the third powder container 123 into one diagonal corner of the rear side of the toughening furnace 500 and returns the third powder container 123 to the transport cart 122, then the transport cart 122 moves the fourth powder container 123 to a position right under the holder 223, and the feeding unit 22 then pours the powder in the fourth powder container 123 into the other diagonal corner of the rear side of the toughening furnace 500 and returns the fourth powder container 123 to the transport cart 122. Therefore, quantitative powder can be automatically added into the toughening furnace 500 at the four opposite corners of the toughening furnace 500 respectively, and uniform addition of the powder is facilitated.
