Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

Example one

As shown in fig. 1 to 5, the present invention provides a hot stamping machine comprising: two upper and lower driving rollers 100 and 200 arranged in parallel with each other, an upper iron sheet 300 fixed to the upper driving roller 100, a lower iron sheet 400 fixed to the lower driving roller 200, and elastic parts 500 rotatably provided at both ends of the lower driving roller 200. The upper driving roller 100 and the lower driving roller 200 can rotate relatively to drive the hot stamping machine of the embodiment to switch different working states so as to complete different working processes; upper and lower iron sheets 300 and 400 can be rotated to a relatively set position and thermoprint a film passing between upper and lower iron sheets 300 and 400; the elastic part 500 can reset the lower driving roller 200 after cutting the film. Meanwhile, in the resetting process, the upper ironing plate 300 and the lower ironing plate 400 are pressed against each other to thermoprint the film. The lower driving roller 200 further has a lower base 700 away from the lower ironing plate 400 on the side wall thereof, the lower base 700 is also shaped like a sheet, and a cutting groove 710 is formed on the side of the lower base 700 away from the lower driving roller 200, the cutting groove 710 corresponds to the sharp corner of the cutting blade 600, and the two sides of the cutting groove 710 are provided with rounded edges 720. After the film is hot stamped, the upper driving roller 100 and the lower driving roller 200 are sequentially rotated to drive the cutter blade 600 and the lower base 700 to be pressed against each other, and the upper driving roller 100 is continuously rotated until the cutter blade 600 is inserted into the cutting groove 710, so that the cutter blade 600 can cut off the part of the film which is hot stamped.

It should be noted that, during the operation of the upper driving roller 100 and the lower driving roller 200, the upper driving roller 100 keeps rotating axially, but is fixed in the vertical direction, and the lower driving roller 200 not only needs to rotate axially, but also needs to move back and forth in the vertical direction. In the process, the lower driving roller 200 can receive intermittent impact to promote the cutting of the film, and meanwhile, the hot stamping speed is slowed down due to the fact that the rotating matching part of the lower driving roller 200 cannot obtain enough lubricating effect, so that the hot stamping effect is poor.

In order to solve the above problem, the following scheme can be adopted: the lower driving roller 200 is hollow inside to form a cavity, a lubricating mechanism 220 is arranged in the inner cavity of the lower driving roller 200, lubricating grease 800 is filled in the lubricating mechanism 220, a telescopic strip groove 210 is formed right above the inner cavity of the lower driving roller 200, the lower base 700 is slidably arranged in the telescopic strip groove 210, and the lower base 700 can continuously spray the lubricating grease 800 to the two sides of the lower driving roller 200 along with the reciprocating movement process of the lower driving roller 200.

Elastic parts 500 are arranged on both sides of the lower driving roller 200, and the elastic parts 500 can continuously spray grease 800 to the sliding connection parts on both sides of the lower driving roller 200 during the reciprocating movement of the lower driving roller 200.

Lubricating mechanism

The lubricating mechanism 220 includes two buffers provided in the lower drive roller 200 in mirror image, a lubricating spring 240 engaging the two buffers, and grease 800 located outside the two buffers. The two buffers are separately disposed and hinged to the lower base 700. The buffering portion comprises a buffering cross rod 221, a buffering slant rod 222 integrated with the buffering cross rod 221, and a rubber plug 223 fixed at the end of the buffering cross rod 221. The lubricating spring 240 has opposite ends fixed to opposite ends of the two buffer rails 221. Grease 800 sets up and keeps away from buffering horizontal pole 221 one side at two plugs 223, and drive roller 200 inner wall under the plug 223 can the shutoff, prevents that grease 800 from leaking. The buffer diagonal rods 222 of the two buffer parts are connected with the hinged part of the lower base 700, when the lower base 700 slides towards the interior of the lower driving roller 200 along the telescopic strip groove 210, the lower base 700 pushes the two buffer diagonal rods 222 to rotate, so that the included angle between the two buffer diagonal rods 222 is increased, and meanwhile, the two buffer diagonal rods 222 drive the two buffer cross rods 221 to slide away from each other along the axial direction of the lower driving roller 200 and extrude the lubricating grease 800 at two sides. At both ends of the lower driving roller 200 are provided flow channels 230 communicating with the elastic part 500. When the lower base 700 is pressed, the buffer portion pushes the grease 800, so that the grease 800 flows toward the elastic portion 500, and meanwhile, the impact force applied to the lower base 700 can be partially absorbed by the lubricating spring 240, thereby playing a role in buffering the lower base 700. After a cutting process is completed, the lubricating spring 240 contracts, pulls the two buffer cross bars 221 to move towards each other, and further pushes the lower bottom table 700 to slide along the telescopic bar groove 210 to drive the roller 200 downwards to the outside, and the original position is recovered.

Elastic part

The elastic part 500 includes an elastic block 510 slidably disposed on the frame 900 and a buffer spring 520. The upper end of the buffer spring 520 abuts against the elastic block 510, and the lower end abuts against the support plate 930 on the side of the frame 900 away from the driving motor 1000. A lubricating bearing 530 is disposed in the elastic block 510, and an inner ring of the lubricating bearing 530 is fixed on the lower driving roller 200. When the upper driving roller 100 rotates until the cutting blade 600 and the lower base 700 are pressed against each other, the upper driving roller 100 continues to rotate and the cutting blade 600 pushes against the lower base 700 by means of the round 720; synchronously, the lower driving roller 200 is pushed to slide away from the upper driving roller 100 and presses the buffer spring 520, and the tip of the cutting blade 600 is inserted into the cutting groove 710 to cut off the film; the upper driving roller 100 continues to rotate to separate the cutting blade 600 from the cutting groove 710, and the buffer spring 520 releases the pressing force to push the elastic block 510 and the lower driving roller 200 back to the original position.

In order to lubricate the lubricated bearing 530, the inner race of the lubricated bearing 530 is provided with a flow port 531 penetrating to the roller of the lubricated bearing 530, the flow port 531 and the flow channel 230 are communicated with each other, and when the lower base 700 is pressed, the buffer part pushes the grease 800, so that the grease 800 flows out through the flow channel 230 and flows into the inner race of the lubricated bearing 530 through the flow port 531.

In addition, in order to enhance the lubricating effect on the outer ring of the lubricating bearing 530, the interior of the elastic block 510 is hollow, the upper end of the elastic block 510 is provided with an opening, the interior of the elastic block 510 is provided with grease 800, the T-shaped block 920 arranged at the lower end of the bearing seat 910 extends into the opening and contacts with the upper end of the grease 800, when the elastic block 510 returns upwards, the T-shaped block 920 is suitable for extruding the grease 800 in the elastic block 510, the inner wall of the elastic block 510 and the outer ring of the lubricating bearing 530 are sequentially provided with an injection channel 532, and after being extruded by the T-shaped block 920, the grease 800 can be injected into the roller of the lubricating bearing 530 through the injection channel 532.
