The working principle is as follows: when the batch type business card stamping machine works, a plurality of business cards 25 to be stamped are placed at the appointed position on the workbench 2, the motor 22 is started, under the action of the driving output shaft 18, the rotary disc 17 is driven to rotate together, when the hinged part of the rotary disc 17 and the first connecting rod 15 rotates from the lower part of the circumference to the higher part, the first connecting rod 15 is driven to move upwards, thereby driving one end of the second connecting rod 9 hinged with the first connecting rod 15 to rotate towards the direction close to the third supporting arm 14, thereby driving one end of the second connecting rod 9 hinged with the chute connecting rod 5 to rotate towards the direction close to the workbench 2, and further drives the chute connecting rod 5 to rotate towards the vertical direction and slide upwards under the matching of the first sliding block 7 and the first chute 6, after the chute connecting rod 5 rotates to pass through an angle which forms a straight line with the second connecting rod 9, which slides downwards while continuing to rotate in the vertical direction under the drive of the second connecting rod 9 in cooperation with the first sliding block 7 and the first sliding groove 6.

Meanwhile, the cylinder 20 on the output shaft 18 is driven to rotate, the tenon 23 is driven to slide in the direction close to the rotary table 17 under the action of the curve sliding grooves 19 connected end to end, the first transmission rod 31 is driven to slide in the same direction in the stepping sliding groove 32, the second transmission rod 30 is driven to move in the same direction, the piston frame 29 is driven to slide in the same direction in the stepping box 33, the horizontal piston plate 27 is driven to move in the same direction in the horizontal direction, the lifting rod 26 rotates in the vertical direction, the horizontal piston plate 27 slides upwards in the piston frame 29 while moving horizontally, the stepping tenon 28 is driven to upwards penetrate through the stepping clamping groove 24, when the piston frame 29 moves to be contacted with the inner wall of the stamping area after the stepping box 33 is close to the stamping area, the stepping box 33 is driven to slide in the stepping cavity 34 together, and the stepping tenon 28 rises to a stable position above the stepping clamping groove 24 and supports against the back edge of the business card 25 to be stamped above the working table 2, with the step box 33 sliding in the step cavity 34, the step tenon 28 simultaneously slides in the step slot 24 and pushes the business card 25 to move forward.

When the hinged position of the rotary disc 17 and the first connecting rod 15 moves to the highest position of the circumference, the first transmission rod 31 slides to a critical point in the direction close to the rotary disc 17 in the stepping sliding groove 32, the stepping tenon 28 pushes the business card 25 to just the stamping area on the workbench 2, in the process, the stamp rod 35, the pre-pressing cross rod 4, the pre-pressing vertical rod 10, the fixed seat 12 and the stamp head 3 move to the business card 25 together under the driving of the sliding groove connecting rod 5, when the fixed seat 12 first contacts the business card 25, the business card 25 is pressed and fixed, along with the continuous movement of the sliding groove connecting rod 5, the fixed seat 12 pushes the pre-pressing vertical rod 10 to slide in the vertical through holes at the two ends of the pre-pressing cross rod 4, meanwhile, the spring 11 deforms and accumulates elastic potential energy, and then the stamp head 3 moves to the surface of the business card 25, so that the stamping action is completed.

Then the hinged part of the rotary disc 17 and the first connecting rod 15 starts to move to the lower part of the circumference, and further drives the first connecting rod 15 to move downwards, and further drives the hinged end of the second connecting rod 9 and the first connecting rod 15 to rotate towards the direction far away from the third supporting arm 14, and further drives the hinged end of the second connecting rod 9 and the chute connecting rod 5 to rotate towards the direction far away from the workbench 2, and further drives the chute connecting rod 5 to rotate towards the horizontal direction while sliding upwards under the matching of the first sliding block 7 and the first chute 6, in the process that the stamp head 3 leaves the card 25, under the deformation of the spring 11, the fixed seat 12 keeps the pressure fixation on the card 25 until the elastic potential energy of the spring 11 is completely released, at the moment, the stamp head 3 completely leaves the card 25, the fixed seat 12 returns to the initial position, when the chute connecting rod 5 rotates to pass through the angle which forms a straight line with the second connecting rod 9, the stamp head continues to rotate in the horizontal direction under the driving of the second connecting rod 9 and the matching of the first sliding block 7 and the first sliding chute 6, and simultaneously slides in the direction close to the first supporting arm 16 until the horizontal position of the sliding chute connecting rod 5 is overlapped with the second supporting arm 8, at the moment, the hinged part of the rotating disc 17 and the first connecting rod 15 moves to the lowest part of the circumference, and the stamp head 3 is contacted with and pressed against the inkpad 13.

Meanwhile, under the action of the end-to-end curved chutes 19 on the cylinder 20, the first transmission rod 31 starts to slide in the stepping chute 32 in a direction away from the rotary table 17, so as to drive the second transmission rod 30 to move in the same direction, further to pull the piston frame 29 to be out of contact with the inner wall of the stepping box 33 and slide in the stepping box 33 in the same direction, further to push the horizontal piston plate 27 to move in the same direction in the horizontal direction, further to rotate the lifting rod 26 in the horizontal direction, so that the horizontal piston plate 27 slides downward in the piston frame 29 while moving horizontally, further to drive the stepping tenon 28 to fall back to the stepping box 33 from the stepping clamping groove 24, when the piston frame 29 moves to contact with the inner wall of the stepping box 33 away from the stamping area, the stepping box 33 is driven to slide in the stepping cavity 34 together, and when the hinged position of the rotary table 17 and the first connection rod 15 moves to the lowest position of the circumference, the first transmission rod 31 slides in the stepping slide groove 32 to the direction far away from the rotating disc 17 to the critical point, the synchronous stepping device returns to the initial position, and then the rotating disc 17 starts to rotate to the high position of the circumference to reciprocate circularly.

By arranging the driving mechanism and the rotary disc, the business cards can be stamped continuously and accurately under the matching of the first connecting rod and the second connecting rod, so that the automatic stamping machine has the advantages of convenience in operation and good stamping effect when batch business cards are stamped, and is superior to the existing products. Simultaneously through setting up the inkpad in specific position, can realize dipping in mud in the in-process of stamping in succession, further optimize the effect of stamping to through setting up synchronous step device, can realize in step with not stamping business card propelling movement to the region of stamping, thereby simplify work flow, improve work efficiency, further liberate the manpower.
