Working principle: when the motor 201 is started to drive the incomplete gear 202 to rotate, and the toothed part of the incomplete gear 202 rotates to be meshed with the bidirectional rack 204, the bidirectional rack 204 can slide downwards along the vertical guide rod 205 under the driving of the incomplete gear 202, and in the process, a return spring I206 positioned between the bidirectional rack 204 and the vertical guide rod 205 can be compressed, and the return spring I206 is used for assisting the return of the bidirectional rack 204. During the downward movement of the bi-directional rack 204, the overprinting mold 210 installed under the bi-directional rack 204 is moved, and the driving frame 212 slidably installed under the bi-directional rack 204 is moved downward together.

Since the two ends of the driving frame 212 are inclined surfaces, the driving frame 212 moves the squeeze plates 404 located at two sides of the horizontal frame 401 in the approaching direction in the downward moving process, the squeeze plates 404 are connected with the positioning plates 402 through the connecting rods 403, so that the two positioning plates 402 are gradually approaching, and at this time, the workpiece 8 conveyed by the conveyor belt 304 is clamped by the two positioning plates 402, so as to complete the fixing and positioning. It should be noted that, the conveyor 304 is provided with a plurality of holding frames 7, the holding frames 7 are used for loading the workpieces 8, and the width of the positioning plate 402 ensures that the positioning plate 402 can slide inside the holding frames 7.

The downwardly moving overprinting die 210 touches the workpiece 8 positioned by the positioning plate 402, and overprinting of the workpiece 8 is completed when the overprinting die 210 is moved downwardly. It should be noted that, since the driving rack 212 is slidably mounted on the bidirectional rack 204, when the driving rack 212 pushes the extrusion plate 404 to the maximum, the driving rack 212 is clamped by the extrusion plate 404, and the second return spring 211 is compressed during the downward movement of the bidirectional rack 204 and the overprinting die 210, so that the movement of the overprinting die 210 is not limited even if the driving rack 212 is not moved downward any more, and the second return spring 211 also helps to assist the resetting of the driving rack 212.

In addition, since the limit ratchet 208 on the cylindrical gear 207 forms a ratchet-pawl engagement with the pawl on the drive shaft 209, even if the cylindrical gear 207 rotates during the downward movement of the bi-directional rack 204, the drive shaft 209 is not rotated, and thus the belt assembly 301 is not rotated, and the conveyor 304 is not rotated, which is to keep the conveyor 304 stationary, providing a stationary environment for the overprinting of the workpiece 8 by the overprinting die 210.

When the motor 201 drives the incomplete gear 202 to rotate to the position where no teeth are formed to face the bidirectional rack 204, at this time, the incomplete gear 202 is no longer meshed with the bidirectional rack 204, so that the bidirectional rack 204 is reset under the action of the first reset spring 206, that is, the bidirectional rack 204 slides upwards along the vertical guide rod 205, meanwhile, the overprinting die 210 and the driving frame 212 move upwards, when the bidirectional rack 204 moves upwards, the bidirectional rack 204 pushes the first reset spring 206 to rotate in the direction, and at this time, the limiting ratchet 208 and the driving shaft 209 which form ratchet pawl matching enable the driving shaft 209 to drive the belt assembly 301 to rotate.

When the belt assembly 301 rotates, the horizontal shaft 302 engaged with the belt assembly 301 is rotated, so that the bevel gear set 303 rotates along with the horizontal shaft 302, and the bevel gear set 303 drives the conveyor belt 304 to rotate, so that the conveyor belt 304 rotating forward conveys the workpiece 8 to be overprinted next forward to the position below the overprinting die 210, and simultaneously conveys the workpiece 8 to be overprinted forward to the position below the pressing head 603.

Specifically, the process that the workpiece 8 to be overprinted arrives on the conveyor belt 304 is that, during the process that the overprinting die 210 moves downward to finish the overprinting of the previous workpiece 8, there are two pressing plates 404 moving toward each other, during the moving of the pressing plates 404, a push rod 501 fixedly installed on the pressing plates 404 will also move, then the push rod 501 slides along the ball on the ball rod 502, and since the push rod 501 is in a state of being obliquely arranged, the push rod 501 pushes the ball rod 502 to slide along the guide frame 506, the sliding direction is that the ball rod 502 gradually approaches the storage cylinder 505, in this process, a return spring four 503 will be compressed, and the function of the return spring four 503 is to assist the reset of the ball rod 502. Since the ball rod 502 is fixedly connected with the tripod 504, the tripod 504 also moves, and one side of the inclined surface on the tripod 504 faces the storage cylinder 505, so that the tripod 504 slides into the storage cylinder 505 and pushes a workpiece 8 out of the blanking mechanism 5 into the clamping frame 7 on the conveyor 304, and one feeding is completed. During the upward movement of the overprinting die 210, the pressing plate 404 slides in a direction away from each other, the push rod 501 and the tripod 504 are reset, and the tripod 504 slides out of the cartridge 505. This completes the feeding.

The motor 201 generates heat during operation, the generated heat is stored in the outer box 601, and because the outer box 601 is communicated with the heat conducting pipe 602, the heat can reach the pressing head 603 through the heat conducting pipe 602 and flows out of the pressing head 603, in the process that the motor 201 and the driving frame 212 move downwards, the driving frame 212 pushes the sliding plate 605 downwards, the sliding plate 605 slides downwards along the U-shaped guide rod 606 and simultaneously presses the pressing head 603 downwards, the pressing head 603 slides out of the heat conducting pipe 602 and stretches the reset spring five 604, the pressing head 603 moving downwards sleeves the workpiece 8 which is finished with the last one, namely, when the overprinting die 210 overprints a new workpiece 8, the pressing head 603 heats the workpiece 8 which is finished with the last one and dries the surface of the workpiece 8, and in the process, the reset spring five functions to assist reset of the pressing head 603 and the sliding plate 605.

It should be noted that, the bevel gear set 303 includes a driving bevel gear and a driven bevel gear, the driving bevel gear is fixedly connected with the horizontal shaft 302 as an input end, and the driven bevel gear is fixedly connected with the rotating shaft on the conveyor belt 304 as an output end. Meanwhile, the belt assembly 301 includes one belt and two pulleys fixedly connected to the horizontal shaft 302 and the driving shaft 209, respectively, and the two pulleys are connected by the belt, which will be apparent to those skilled in the art.
