Working principle: Start the motor 201, so that the output shaft of the motor 201 drives the incomplete gear 202 to rotate. When the toothed part of the incomplete gear 202 rotates to mesh with the bidirectional rack 204, the bidirectional rack 204 will be on the incomplete gear. Driven by 202, it slides downwards along the vertical guide bar 205. In this process, the return spring one 206 located between the two-way rack 204 and the vertical guide bar 205 will be compressed. The function of the return spring one 206 is to assist the two-way rack 204 reset. During the downward movement of the bidirectional rack 204 , the overprinting mold 210 installed under the bidirectional rack 204 will move, and the driving frame 212 slidably installed under the bidirectional rack 204 will move downward together.

Since the two ends of the drive frame 212 are inclined surfaces, the drive frame 212 will move the extrusion plates 404 located on both sides of the horizontal frame 401 toward each other when the drive frame 212 moves downward, and the extrusion plates 404 pass through the connecting rod 403 It is connected with the positioning plate 402, so the two positioning plates 402 will gradually approach. At this time, the workpiece 8 conveyed by the conveyor belt 304 will be clamped by the two positioning plates 402 to complete the fixed positioning. It should be noted that the conveyor belt 304 is provided with a plurality of clamping frames 7 for loading the workpiece 8 , and the width of the positioning plate 402 ensures that the positioning plate 402 can slide inside the clamping frame 7 .

The overprinting mold 210 moving downward touches the workpiece 8 positioned by the positioning plate 402 , and when the overprinting mold 210 moves downward, the overprinting of the workpiece 8 is completed. It should be noted that, since the drive frame 212 is slidably installed on the bidirectional rack 204, when the drive frame 212 pushes the extruding plate 404 to the maximum, the driving frame 212 is blocked by the extruding plate 404. At this time, the bidirectional rack 204 and the overprinting mold 210 move downwards, the return spring 2 211 will be compressed, even if the drive frame 212 no longer moves downwards, it will not limit the movement of the overprinting mold 210, and the return spring 2 211 also helps to assist The reset of drive frame 212.

In addition, because the limit ratchet 208 on the cylindrical gear 207 and the pawl on the transmission shaft 209 form a ratchet pawl fit, so even if the cylindrical gear 207 rotates during the downward process of the bidirectional rack 204, the transmission will not be activated. The shaft 209 rotates, so that the belt assembly 301 does not rotate, and the conveyor belt 304 does not rotate. The purpose of doing this is to keep the conveyor belt 304 stationary and provide a static environment for the overprint mold 210 to overprint the workpiece 8 .

When the motor 201 drives the incomplete gear 202 to rotate to the part without teeth towards the two-way rack 204, the incomplete gear 202 is no longer meshed with the two-way rack 204, so the two-way rack 204 will be in the position of the return spring one 206. Resetting under action, that is, the bidirectional rack 204 slides upwards along the vertical guide bar 205, and the overprinting mold 210 and the driving frame 212 also move upward at the same time. When the bidirectional rack 204 moves upward, the bidirectional rack 204 will push The return spring 1 206 rotates in one direction, and at this time, the limit ratchet 208 and the transmission shaft 209 that form the cooperation of the ratchet pawl will make the transmission shaft 209 drive the belt assembly 301 to rotate.

When the belt assembly 301 rotates, the horizontal shaft 302 that forms a pulley with the belt assembly 301 will rotate, and then the bevel gear set 303 will rotate together with the horizontal shaft 302, so that the bevel gear set 303 drives the conveyor belt 304 to rotate, In this way, the conveyor belt 304 rotating forward will transport the next workpiece 8 to be overprinted forward to the bottom of the overprinting mold 210 , and simultaneously transport the workpiece 8 that has just been overprinted to the bottom of the pressing head 603 forward.

Specifically, the process that the workpiece 8 to be overprinted arrives on the conveyor belt 304 is that when the overprinting mold 210 moves downward to complete the overprinting of the previous workpiece 8, there is a tendency for the two extrusion plates 404 to move toward each other. process, during the movement of the extrusion plate 404, the push rod 501 fixedly installed on the extrusion plate 404 will also move, then the push rod 501 will slide along the ball on the ball head rod 502, and because the push rod 501 is a state of inclined arrangement, so the push rod 501 will push the ball head rod 502 to slide along the guide frame 506, and the sliding direction is that the ball head rod 502 gradually approaches the storage barrel 505, and the return spring 4 503 will be compressed during this process , The effect of back-moving spring 4 503 is to assist ball head rod 502 to reset. Because the ball head rod 502 is fixedly connected with the tripod 504, the tripod 504 will also move, and the side of the slope on the tripod 504 faces the storage barrel 505, so the tripod 504 slides into the storage barrel 505 and a workpiece 8 from below Push out in the holding frame 7 on the conveyer belt 304 in the material mechanism 5, complete a feeding. During the upward movement of the overprinting mold 210 , the extrusion plate 404 slides away from each other, the push rod 501 and the tripod 504 reset, and the tripod 504 slides out from the storage barrel 505 . This completes the feed.

The motor 201 will generate heat during operation, and the generated heat will be stored in the outer box 601. Since the outer box 601 communicates with the heat pipe 602, the heat will reach the pressing head 603 through the heat pipe 602, and from the pressing head 603 When the motor 201 and the drive frame 212 are moving downward, the drive frame 212 will push the slide plate 605 downward, so that the slide plate 605 slides down along the U-shaped guide bar 606 and at the same time pushes the pressing head 603 to the Press down, and the pressing head 603 slides out from the heat pipe 602, and stretches the return spring 5 604, and the pressing head 603 moving downwards will enclose the last finished overprinted workpiece 8, that is, in the overprinting mold 210 for a When a new workpiece 8 is overprinted, the pressing head 603 will heat the last workpiece 8 that has been overprinted, and dry the surface of the workpiece 8. In this process, the function of the return spring 5 604 is to assist Reset of the pressing head 603 and the slide 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 to the horizontal shaft 302 as the input end, and the driven bevel gear is fixedly connected to the rotating shaft on the conveyor belt 304 as the output end . Meanwhile, the belt assembly 301 includes a belt and two pulleys, the two pulleys are fixedly connected with the horizontal shaft 302 and the drive shaft 209 respectively, and the two pulleys are connected by a belt, which is conceivable for those skilled in the art .
