[0014] Preferably, a support plate is fixedly connected to the left outer wall of the shell, and the lower surface of the grab plate is slidably connected to the upper surface of the support plate.

[0015] Working principle: when the device needs to be used, turn on the motor and rotate it counterclockwise. When the motor rotates, it will drive the threaded rod to rotate. When the threaded rod rotates, it will drive the ratchet to rotate. When the ratchet rotates, the pawl will keep stuck in the ratchet. At the same time, the ratchet will drive the pawl to rotate, and then the pawl will drive sprocket two to rotate. When sprocket two rotates, it will drive the chain to rotate. When the chain rotates, it will drive sprocket one to rotate. When the chain rotates, it will drive the connecting shaft to rotate. When the outer wall of the connecting shaft rotates on the outer wall of the bracket, it will drive the centrifugal disc to rotate. When the centrifugal disc rotates, it will drive the turntable on its outer wall to rotate. Since the centrifugal disc is an eccentric structure, it will drive the rotating plate two to tilt forward while the turntable rotates. At the same time, the rotating plate two will drive the rotating plate one to rotate. The support block one is used to support the rotating plate one to rotate. When the rotating plate two tilts forward, it will cause the rotating plate three to rotate slightly and move forward. When the rotating plate three moves forward, its outer wall will rotate on the outer wall of the support block two and drive the grab plate to move forward. When the grab plate moves forward, it will drive the gripper and The rebound shaft moves forward. When the outer wall of the rebound shaft moves to the outer wall of the mold, the blocking column at the rear of the mold prevents it from moving backward. At the same time, the bottom of the rebound shaft is designed with a double-sided inclined surface. The inclined surface on the right side will be under pressure to make the rebound shaft compression spring enter the inside of the gripper. When the rebound shaft is compressed by pressure and enters the inside of the gripper, the gripper and the gripping plate will slide over the upper surface of the mold. When the front end of the gripper slides over the upper surface of the mold, the spring will pop it out. When the spring pops out the rebound shaft, the centrifugal disc will rotate half a circle. When the centrifugal disc rotates half a circle and then continues to rotate, the rotating plate 2 will tilt backwards. When the rotating plate 2 tilts backwards, the rebound shaft will hook the right outer wall of the mold and pull the mold to move toward the support. When the left outer wall of the mold moves to the right outer wall of the block, the mold will be unable to move forward due to the resistance of the block and will remain on the upper surface of the support. At the same time, the left inclined surface of the rebound shaft will be pressurized to enter the inside of the gripper. Then, when the centrifugal disc rotates one circle, the mold is brought into the upper surface of the support, and the rest of the structure is reset. Then make the motor rotate clockwise. When the motor rotates clockwise, it will continue to drive the threaded rod to rotate, and at the same time, the threaded rod drives the ratchet to rotate. When the ratchet rotates clockwise, the pawl cannot engage with it, so it does not drive the second sprocket to rotate. When the threaded rod rotates, it will drive the sliding block to slide. When the sliding block slides, it will drive the fixed claw to slide, and cooperate with the baffle to clamp the mold on the upper surface of the support. Then turn on the shaping heating plate to make it descend. When the shaping heating plate descends to the upper surface of the mold, it will heat and melt the plastic particles inside the mold. After the melted plastic particles inside the mold cool down, they can be formed. When the shaping heating plate descends to the upper surface of the mold, the telescopic shaft will be pressed. When the telescopic shaft is pressed down, the slider will be driven down. When the slider descends, the spring 2 will be compressed. When the slider descends, the adjustment shaft will first rise inside the heart-shaped groove. Because of the shape of the heart-shaped groove, the adjustment shaft will drive the adjustment plate to rotate to the left when it rises. When the adjustment plate rotates to the left, the adjustment shaft will also rotate to the left. When the shaping heating plate leaves the upper surface of the mold, the spring 2 will rebound and push the slider up. At the same time, the adjustment shaft will descend on the left side of the heart-shaped groove. Then the slider will drive the telescopic shaft to slide up at the same time. When the hot pressing is completed, the motor rotates counterclockwise again, driving the threaded rod to rotate so that the fixed claw releases the clamping fixation on the mold, and continues to drive the gripper to move to the right. Since there is a protruding rectangular block on the outer wall of the gripper on both sides of the gripper plate, the rectangular block will hit the rising telescopic shaft when moving to the right again, and then push the mold to move to the outer wall of the blocking column, and the gripper plate will drive the gripper to reset.

[0016] The present invention provides a hot melt processing device for producing plastic parts. It has the following beneficial effects: 1. The present invention drives the gripper and the rebound shaft to move forward by turning on the motor and drives the mold to the upper surface of the support, so as to automatically place the mold inside the device, which can greatly reduce the safety risks in the production process. The hot melt processing device has a high temperature when working, and manual operation may cause safety hazards such as burns. Automatic placement of the mold reduces the contact of human hands near high-temperature equipment, thereby effectively reducing safety risks.

[0017] 2. The present invention makes the motor rotate clockwise, drives the fixed claw to slide, and cooperates with the baffle to clamp and fix the mold, so that the mold can be clamped and fixed to ensure that the mold remains stable during the processing and avoid position deviation or shaking. During the hot melt processing, the melting and cooling of the plastic need to be carried out under precise conditions. The fixation of the mold can ensure that the size and shape of the product meet the design requirements and improve the processing accuracy.

[0018] 3. The present invention enables the motor to rotate clockwise, driving the fixed claw to slide, and cooperates with the baffle to clamp and fix the mold. At the same time, it can also adapt to molds of different sizes and be compatible with molds of different shapes, sizes and types, making it suitable for diversified production tasks. In the production process of plastic parts, different products usually need to replace different molds. The device with adaptive clamping function can quickly adjust the clamping scheme without the need for additional equipment modification. It is suitable for various production tasks, greatly improving the flexibility and versatility of the equipment.

[0019] 4. After the hot pressing is completed, the motor of the present invention rotates counterclockwise, and then pushes the mold to move to the outer wall of the blocking column, so that the processed mold can be automatically pushed out and unloaded. The automatic pushing out and unloading function can quickly push out the finished product in the mold immediately after the processing is completed, without manual intervention or shutdown processing, thereby improving the overall production efficiency.

[0020] 5. All operations of the present invention do not require human intervention. Automatic operation enables the device to operate continuously and quickly. The entire production process can be seamlessly connected from loading, heating to unloading, which greatly shortens the production cycle of each product and increases the output per unit time. This efficiency improvement is particularly suitable for batch and standardized production needs and can greatly improve the overall production capacity. BRIEF DESCRIPTION OF THE DRAWINGS

The transmission assembly 12 includes a sprocket 1 1201, the inside of the sprocket 1 1201 is fixedly connected to the right outer wall of the connecting shaft 7, the outer wall of the sprocket 1 1201 is meshedly connected with a chain 1202, and the inner wall of the chain 1202 is meshedly connected with a sprocket 2 1203. The front outer wall of the housing 1 is fixedly connected with a support plate 16, the outer wall of the second sprocket 1203 is rotatably connected to the outer wall of the support 2101, the upper surface of the support plate 16 is fixedly connected with a motor 17, the output end of the motor 17 is fixedly connected with a threaded rod 18, the outer wall of the threaded rod 18 is fixedly connected with a ratchet 19, the outer wall of the second sprocket 1203 is rotatably connected with a pawl 20, the outer wall of the pawl 20 is meshedly connected with the outer wall of the ratchet 19, a fixing assembly 21 is arranged inside the housing 1, and a mold 22 is arranged on the right upper surface of the housing 1. A stop column 25 is fixedly connected to the right upper surface of the housing 1, and the right outer wall of the mold 22 is attached to the left outer wall of the stop column 25.

[0025] Specifically, when the device is needed, first place the mold 22 filled with plastic particles on the outer wall of the blocking column 25 to fit it, and then start the motor 17 to rotate counterclockwise. When the motor 17 rotates, it will drive the threaded rod 18 to rotate. When the threaded rod 18 rotates, it will drive the ratchet 19 to rotate. When the ratchet 19 rotates, the pawl 20 will keep stuck on the ratchet 19. At the same time, the ratchet 19 will drive the pawl 20 to rotate. Then the pawl 20 will drive the sprocket wheel 2 1203 to rotate. When the sprocket wheel 2 1203 rotates, it will drive the chain 1202 to rotate. When the chain 1202 rotates, it will drive the sprocket wheel 1 1201 to rotate. When the chain 1202 rotates, it will The connecting shaft 7 is driven to rotate. When the outer wall of the connecting shaft 7 rotates on the outer wall of the bracket 2, the centrifugal disc 8 is driven to rotate. When the centrifugal disc 8 rotates, the turntable 6 on its outer wall is driven to rotate. A track is provided inside the centrifugal disc 8. The turntable 6 is installed between the tracks inside the centrifugal disc 8. The spring three 28 pulls the rotating plate two 5 to fit in the direction of the centrifugal disc 8. The rotating plate two 5 drives the turntable 6 to always fit in with the centrifugal disc 8. Since the centrifugal disc 8 is an eccentric structure, the rotating plate two 5 is driven to tilt forward when the turntable 6 rotates. At the same time, the rotating plate two 5 drives the rotating plate one 4 to rotate. The support block one 3 is used to support the rotating plate one 4 for rotation. When the rotating plate two 5 tilts forward, it will bring the rotating plate three 9 It rotates slightly and moves forward. When the rotating plate three 9 moves forward, its outer wall will rotate on the outer wall of the support block two 10 and drive the grab plate 11 to move forward. When the grab plate 11 moves forward, it will drive the gripper 13 and the rebound shaft 15 to move forward. When the outer wall of the rebound shaft 15 moves to the outer wall of the mold 22, the blocking column 25 is behind the mold 22 to prevent it from moving backward. At the same time, the bottom of the rebound shaft 15 is designed with a double-sided inclined surface. The inclined surface on the right side will be subjected to pressure to cause the rebound shaft 15 to compress the spring 14 and enter the interior of the gripper 13. When the rebound shaft 15 is compressed by pressure and enters the interior of the gripper 13, the gripper 13 and the grab plate 11 will slide over the upper surface of the mold 22. When the front end of the gripper 13 slides over the upper surface of the mold 22 The spring 14 will pop it out. When the spring 14 pops out the rebound shaft 15, the centrifugal disc 8 will rotate half a circle. When the centrifugal disc 8 continues to rotate after rotating half a circle, the rotating plate 25 will tilt backward. When the rotating plate 25 tilts backward, the rebound shaft 15 will hook the outer wall of the mold 22 and pull the mold 22 to move toward the direction of the support 2101. When the left outer wall of the mold 22 moves to the right outer wall of the stopper 27, the mold 22 will be unable to move forward due to the resistance of the stopper 27 and remain on the upper surface of the support 2101. At the same time, the left inclined surface of the rebound shaft 15 will be pressurized to make it enter the interior of the gripper 13. Then, after the centrifugal disc 8 rotates one circle, the mold 22 is brought to the upper surface of the support 2101.The remaining structures are reset, so that the mold 22 can be automatically placed inside the device, which can greatly reduce the safety risks in the production process. The temperature of the hot melt processing device is high when it is working, and manual operation may cause safety hazards such as burns. Automatic placement of the mold 22 reduces the contact of human hands near high-temperature equipment, thereby effectively reducing safety risks.

[0026] Please refer to the attached Figure 1 , Attachment Figure 6 and attached Figure 7 The fixing assembly 21 includes a support 2101, the outer wall of the support 2101 is fixedly connected to the inside of the shell 1, the upper surface of the support 2101 is fixedly connected to a baffle 2102, the inside of the support 2101 is slidably connected to a sliding block 2103, the internal thread of the sliding block 2103 is connected to the outer wall of the threaded rod 18, the lower surface of the sliding block 2103 is fixedly connected to a fixing claw 2104, and the upper surface of the fixing claw 2104 is slidably connected to the lower surface of the support 2101.

[0027] Specifically, after the mold 22 is placed, the motor 17 is rotated clockwise. When the motor 17 rotates clockwise, the threaded rod 18 will continue to be driven to rotate, and the threaded rod 18 will drive the ratchet 19 to rotate. When the ratchet 19 rotates clockwise, the pawl 20 cannot engage with it, so the sprocket 2 1203 is not driven to rotate. When the threaded rod 18 rotates, the sliding block 2103 will be driven to slide. When the sliding block 2103 slides, the fixed claw 2104 will be driven to slide. The baffle 2102 is used to clamp and fix the mold 22 on the upper surface of the support 2101, so that the mold 22 can be clamped and fixed, and the mold 22 can be ensured to remain stable during the processing to avoid position deviation or shaking. During the hot melt processing, the melting and cooling of the plastic need to be carried out under precise conditions. The fixation of the mold 22 can ensure that the size and shape of the product meet the design requirements and improve the processing accuracy. It can also adapt to molds 22 of different sizes, and can be compatible with molds 22 of different shapes, sizes and types, so that it is suitable for diversified production tasks. During the production of plastic parts, different products usually require the replacement of different molds 22. The device with adaptive clamping function can quickly adjust the clamping scheme without additional equipment modification. It is suitable for various production tasks and greatly improves the flexibility and versatility of the equipment.

[0028] Please refer to the attached Figure 8 and attached Fig. 9The upper inner part of the mold 22 is fixedly connected with a rebound stop shaft assembly 23. The rebound stop shaft assembly 23 includes a connecting shell 2301, the outer wall of the connecting shell 2301 is fixedly connected to the upper inner part of the mold 22, a spring 2302 is arranged inside the connecting shell 2301, a slider 2303 is fixedly connected to the top of the spring 2302, a heart-shaped groove 2304 is provided inside the slider 2303, a telescopic shaft 2305 is fixedly connected to the upper surface of the slider 2303, an adjustment plate 2306 is rotatably connected to the outer wall of the connecting shell 2301, and an adjustment shaft 2307 is fixedly connected to the upper inner part of the adjustment plate 2306. The outer wall of the telescopic shaft 2305 is slidably connected to the inner part of the connecting shell 2301, and the outer wall of the adjustment shaft 2307 is arranged inside the heart-shaped groove 2304. A shaping heating plate 24 is arranged inside the upper inner part of the outer shell 1, and a stopper 27 is fixedly connected to the upper left surface of the support 2101. A support plate 26 is fixedly connected to the left outer wall of the housing 1 , and a lower surface of the gripping plate 11 is slidably connected to an upper surface of the support plate 26 .

[0029] Specifically, the shaping heating plate 24 is then turned on to make it descend. The shaping heating plate 24 is a structure that is well known and indispensable to those skilled in the art when processing the mold 22, so no excessive structural description is given. When the shaping heating plate 24 descends to the upper surface of the mold 22, it will heat and melt the plastic particles inside the mold 22. After the heating is completed, it will rise again. After the melted plastic particles inside the mold 22 are cooled, they can be formed. When the shaping heating plate 24 descends to the upper surface of the mold 22, the telescopic shaft 2305 will be pressed. When the telescopic shaft 2305 is pressed down, the slider 2303 will be driven in. When the slider 2303 descends, the spring 2302 will be compressed. When the slider 2303 descends, the adjusting shaft 2307 will first rise inside the heart-shaped groove 2304. The adjusting shaft 2307 will rise because of the shape of the heart-shaped groove 2304 and will drive the adjusting plate 2306 to rotate left. When the adjusting plate 2306 rotates left, the adjusting shaft 2307 will also rotate left. When the shaping heating plate 24 leaves the upper surface of the mold 22, the spring 2302 will rebound and push the slider 2303 to rise. When the pressing is completed, the motor 17 is rotated counterclockwise to drive the threaded rod 18 to rotate so that the fixed claw 2104 releases the clamping fixation on the mold 22, and at the same time, the gripper 13 is driven to move toward the blocking column 25. Since the outer wall of the gripper 13 on both sides of the gripper 11 has a protruding rectangular block, the rectangular block will hit the rising telescopic shaft 2305 when moving, and then push the mold 22 to move to the outer wall of the blocking column 25, and the gripper 13 on both sides of the gripper 11 has a protruding rectangular block. The plate 11 then drives the gripper 13 to reset. The next time it is used, the telescopic shaft 2305 is pressed once to make the adjustment shaft 2307 rise to the upper inner side of the heart-shaped groove 2304, and then placed on the outer wall of the retaining column 25 to fit it. This can achieve the automatic ejection and unloading of the finished mold 22. The automatic ejection and unloading function can quickly eject the finished product in the mold 22 immediately after the processing is completed, without manual intervention or shutdown processing, thereby improving the overall production efficiency, and all operations do not require manual intervention. The automated operation enables the device to operate continuously and quickly without human intervention. The entire production process can be seamlessly connected from loading, heating to unloading, greatly shortening the production cycle of each product and increasing the output per unit time. This efficiency improvement is particularly suitable for batch and standardized production needs, and can greatly improve the overall production capacity.
