[0009] Optionally, the coating assembly includes a mounting bracket fixedly installed on the outer wall of the lower shell. Two bearing seats are fixedly installed on the outer wall of the mounting bracket, and two winding rollers are rotatably installed between the two bearing seats. The outer walls of the two winding rollers are each wound with a coating portion. A driving assembly is installed on the outer wall of the mounting bracket. The driving assembly can drive the winding rollers to wind up the coating portion. The outer wall of the coating portion can contact the outer walls of the lower mold and the upper mold. One end of the coating portion is fixedly connected to the outer wall of the winding roller. A support assembly is provided between the two coating portions. The support assembly can effectively support the coating portion.

[0010] Optionally, the drive assembly includes a second motor fixedly mounted on the outer wall of the mounting frame, with a worm gear fixedly connected to the output end of the second motor, and a worm wheel fixedly connected to one end of one of the winding rollers, wherein the worm gear and the worm wheel are meshed.

[0011] Optionally, the support assembly includes hinged ears fixedly mounted on the outer wall of the bearing seat, with a first connecting rod hinged to the outer wall of each of the two hinged ears, and a hinged platform fixedly connected to the other end of the coating part, with a second connecting rod hinged to both ends of the hinged platform, and one end of the first connecting rod hinged to the second connecting rod.

[0012] Optionally, gears are fixedly mounted on the other side of each of the two winding rollers, and the two gears mesh.

[0013] Optionally, two liquid storage chambers are fixedly installed on the bearing seat. The lower surface of the liquid storage chamber is close to the application part.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: When the equipment is running, the hydraulic column pushes the limiting plate to drive the upper mold to move downward. When it moves to the preset position, it cooperates with the lower mold to achieve hot pressing of PET material. The cooperation between the feeding component and the discharging component can effectively improve production efficiency. The coating component can apply anti-sticking agent to the surface of the upper and lower molds to prevent PET material from sticking to the mold surface during hot pressing, thus preventing PET material from adhering to the mold and improving the service life of the mold. In addition, multiple limiting rods are fixedly installed on the top of the lower shell, and the limiting plate is slidably installed on the outer wall of the limiting rods. This design can ensure the accurate position of the mold, so that the PET material can obtain uniform force and pressure distribution during hot pressing. The combination of the limiting rod and the limiting plate prevents the mold from shifting during use, improving the hot pressing effect. Simultaneously, a hydraulic column is fixedly installed on the inner top of the upper shell, and the output end of the hydraulic column is fixedly connected to the outer wall of the limiting plate. The hydraulic column provides stable pressure and force, ensuring a certain pressure is maintained between the upper and lower molds during the hot pressing process. This design guarantees uniform heating and plastic deformation of the PET material during hot pressing. The design and installation of the above structure improve the accuracy and efficiency of the hot pressing process, while reducing product damage and mold wear, thereby lowering production costs. Furthermore, the feeding and discharging components improve production efficiency, and the installation of the coating component prevents the formation of adhesive residues, further improving the quality of the finished product and the service life of the mold.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 8This invention provides a technical solution: a high-precision PET hot pressing molding device, comprising an upper shell 1 and a lower shell 2. Multiple limiting rods 14 are fixedly installed on the top of the lower shell 2, and limiting plates 15 are slidably installed on the outer walls of the multiple limiting rods 14. A hydraulic column 16 is fixedly installed on the inner top of the upper shell 1, and the output end of the hydraulic column 16 is fixedly connected to the outer wall of the limiting plate 15. A lower mold 13 is installed on the top of the lower shell 2, and an upper mold 27 is installed on the bottom of the limiting plate 15. The lower mold 13 and the upper mold 27 cooperate to hot press PET material. A feeding assembly is provided on one side of the lower shell 2. On the other side of shell 2, a discharge assembly is provided. A coating assembly is fixedly installed on the outer wall of the lower shell 2. The coating assembly can apply an anti-sticking agent to the surfaces of the lower mold 13 and the upper mold 27. In this invention, during equipment operation, the hydraulic column 16 pushes the limiting plate 15 to drive the upper mold 27 downwards. When it reaches the preset position, it cooperates with the lower mold 13 to achieve hot pressing of the PET material. The cooperation between the feeding assembly and the discharge assembly can effectively improve production efficiency. The coating assembly can apply the anti-sticking agent to the surfaces of the upper mold 27 and the lower mold 13 to prevent the PET material from sticking to the mold surface during hot pressing, thus preventing the PET material from... Material adheres to the mold, improving its service life. Multiple limiting rods 14 are fixedly installed on the top of the lower shell 2, while the limiting plate 15 slides on the outer wall of the limiting rods 14. This design ensures accurate mold positioning, allowing the PET material to receive uniform force and pressure distribution during hot pressing. The combination of the limiting rods 14 and the limiting plate 15 prevents mold displacement during use, improving the hot pressing effect. Simultaneously, a hydraulic column 16 is fixedly installed on the inner top of the upper shell 1, and the output end of the hydraulic column 16 is fixedly connected to the outer wall of the limiting plate 15. The hydraulic column 16 provides stable pressure and force, ensuring a certain pressure is maintained between the upper mold 27 and the lower mold 13 during hot pressing. This design ensures uniform heating and plastic deformation of the PET material during hot pressing. The design and installation of the above structures improve the accuracy and efficiency of the hot pressing process, while reducing product damage and mold wear, thereby reducing production costs. In addition, the setting of the feeding and discharging components can improve production efficiency, and the installation of the coating component can prevent the formation of adhesives, further improving the quality of the finished product and the service life of the mold.

[0028] In a preferred embodiment, the feeding assembly includes a feeding roller 18 rotatably mounted on the assembly frame. Second guide rods 28 are movably mounted on both the inner and outer sides of the assembly frame. A photoelectric sensor 3 is fixedly mounted on the bottom of the assembly frame. The feeding assembly can cooperate with the discharging assembly. In this embodiment, please refer to... Figure 2 and Figure 3Firstly, the feeding assembly quantitatively introduces PET material into the hot-pressing area, working in conjunction with the discharging assembly to achieve continuous material feeding and discharging. This reduces the operator's workload and time, improving production efficiency. The rotation of the feeding roller 18 and the movable installation of the second guide rod 28 ensure smooth material entry into the hot-pressing area, guaranteeing stable material transfer and correct positioning, preventing uneven material accumulation and blockage. The movable installation of the second guide rod 28 can be adjusted according to the size and shape of the material, ensuring correct guidance and positioning during the feeding process. Secondly, the feeding assembly, by controlling the rotation speed of the feeding roller 18 and the signal from the photoelectric sensor 3, can achieve precise metering of PET material. The photoelectric sensor 3 can detect the material's arrival and departure, ensuring that the quantity fed each time is exactly as required. This avoids material waste and shortages, ensuring product consistency and quality. Moreover, it can monitor the material status in the feeding area in real time. When the photoelectric sensor 3 detects an abnormality, such as excessive material accumulation or blockage, it can promptly issue an alarm or stop feeding, ensuring the safety of the operator and equipment.

[0029] Furthermore, the discharge assembly includes a receiving roller 5 rotatably mounted on an assembly frame, a transmission roller 6 rotatably mounted on the side of the assembly frame near the bottom, a plurality of first guide rods 11 movably mounted on the outer wall of the assembly frame, a filter roller 17 rotatably mounted in the middle part of the assembly frame, and a first motor 8 fixedly mounted on the outer wall of the assembly frame. The output end of the first motor 8 is connected to the receiving roller 5. In this embodiment, please refer to... Figures 1 to 3 The design of the discharge assembly allows materials to smoothly leave the hot pressing area. Working in conjunction with the feeding assembly, it enables continuous material feeding and discharging. The rotation of the receiving roller 5 and the installation of the transmission roller 6 smoothly guide the material away from the hot pressing area, ensuring smooth material discharge. This reduces the operator's labor intensity and time, and improves production efficiency. The first guide rod 11 is movable and installed on the outer wall of the assembly frame, which can guide and position the material. By adjusting the position of the first guide rod 11, it can be ensured that the material will not accumulate or block during the discharge process, thus ensuring smooth material discharge and avoiding production failures and downtime. Moreover, the filter roller 17 in the discharge assembly can filter the material. The rotation of the filter roller 17 is installed in the middle part of the assembly frame, which can effectively remove waste generated during production. This can improve product quality and consistency, avoid impurities from damaging the equipment and products, effectively improve production efficiency, ensure product quality, and improve work safety.

[0030] Furthermore, the coating assembly includes a mounting bracket 29 fixedly mounted on the outer wall of the lower shell 2. Two bearing seats are fixedly mounted on the outer wall of the mounting bracket 29, and two winding rollers 25 are rotatably mounted between the two bearing seats. The outer walls of both winding rollers 25 are wound with coating portions 19. A driving assembly is mounted on the outer wall of the mounting bracket 29, which drives the winding rollers 25 to wind the coating portions 19. The outer walls of the coating portions 19 can contact the outer walls of the lower mold 13 and the upper mold 27. One end of the coating portion 19 is fixedly connected to the outer wall of the winding roller 25. A support assembly is provided between the two coating portions 19, which effectively supports the coating portions 19. In this embodiment, please refer to... Figure 5 The mounting bracket 29 is fixedly installed on the outer wall of the lower shell 2. Through the rotation of two bearing seats and two winding rollers 25, the coating part 19 is ensured to contact the outer walls of the lower mold 13 and the upper mold 27. This guarantees uniform contact between the coating part 19 and the mold surface, achieving a stable coating effect. Simultaneously, the outer wall of the coating part 19 has an anti-sticking agent, allowing for precise application of the anti-sticking agent to the mold surface, ensuring the uniformity and consistency of the coating. The drive assembly is installed on the outer wall of the mounting bracket 29 and drives the winding rollers 25 to rewind the coating part 19. The drive assembly is controlled... The operation allows for adjustment of the amount of anti-sticking agent and the application speed of the coating section 19, thereby achieving precise control over the coating thickness and application speed. This improves production efficiency, saves paint usage, and reduces costs. Furthermore, one end of the coating section 19 is fixedly connected to the outer wall of the roll roller 25. Through the setting of the support component, the coating section 19 can be effectively supported, thus preventing deformation and swaying of the coating section 19 and ensuring the uniformity and quality of the coating. The support component can also automatically adjust according to the changes in the coating section 19 to ensure uniform distribution of paint and consistency of the coating.

[0031] Furthermore, the drive assembly includes a second motor 9 fixedly mounted on the outer wall of the mounting bracket 29. A worm gear 21 is fixedly connected to the output end of the second motor 9, and a worm wheel 22 is fixedly connected to one end of one of the winding rollers 25. The worm gear 21 and the worm wheel 22 are meshed. In this embodiment, please refer to... Figure 5Firstly, the worm gear 21 and worm wheel 22 form a highly efficient transmission mechanism, characterized by a large transmission ratio, high transmission efficiency, and smooth transmission. The worm gear 21 has a worm helix shape, while the worm wheel 22 has a corresponding shape. When the worm gear 21 and worm wheel 22 mesh, the rotation of the worm gear 21 drives the rotation of the worm wheel 22, thus achieving a large transmission ratio, ensuring stable transmission of driving force, and reducing vibration and noise during transmission. Moreover, the meshing of the worm gear 21 and worm wheel 22 has a self-locking characteristic, even in the event of a power outage or motor failure. The worm gear 22 will not rotate on its own. This self-locking characteristic can effectively prevent the equipment from moving or sliding unexpectedly, thus improving the safety of the equipment. At the same time, the meshing of the worm 21 and the worm gear 22 also has good transmission accuracy and repeatability, which can ensure the reliable operation of the drive components and improve working stability. In addition, the worm gear 21 and worm gear 22 transmission mechanism has a compact structure and occupies little space, making it suitable for installation in limited spaces. Compared with other transmission mechanisms, the worm gear 21 and worm gear 22 transmission is simpler, reducing the number and complexity of parts, and lowering manufacturing and maintenance costs.

[0032] Furthermore, the support assembly includes hinge ears 30 fixedly mounted on the outer wall of the bearing housing. Each of the two hinge ears 30 has a first connecting rod 24 hinged to its outer wall. The other end of the coating part 19 is fixedly connected to a hinge platform 31. Both ends of the hinge platform 31 are hinged to second connecting rods 32. One end of the first connecting rod 24 is hinged to the second connecting rod 32. In this embodiment, please refer to... Figure 5 and Figure 7 The hinged connection between the first link 24 and the second link 32 enables the support assembly to have a flexible motion mechanism, which can support the winding of the coating part 19. The first link 24 is connected to the hinge ear 30, and the coating part 19 is connected to the second link 32 through the hinge platform 31. When the position of the coating part 19 changes, the first link 24 and the second link 32 can rotate and adjust freely to support the winding and unwinding of the coating part 19. This hinged connection makes the movement of the coating assembly smoother, reduces friction and resistance, and improves the flexibility and operability of the equipment. At the same time, the design of the hinge ear 30 and the link can provide sufficient rigidity for the system to ensure that there is no excessive deformation or vibration during operation, thereby improving the stability of the entire system.

[0033] Furthermore, gears 23 are fixedly mounted on the other side of each of the two winding rollers 25, and the two gears 23 mesh with each other. In this embodiment, please refer to... Figure 6Firstly, through the meshing of gear 23, the other side of the two roll rollers 25 can achieve synchronous movement. This helps to ensure that the roll rollers 25 remain relatively parallel and synchronous during operation, thereby effectively coordinating the winding process of the coating section 19. Moreover, due to the synchronous movement and precise transmission of the roll rollers 25, the system's working efficiency may be improved, which is crucial for large-scale production and automated processes because it can increase production speed. Furthermore, gear 23 is usually designed as a robust and durable component that can withstand considerable loads and frequent movements, which means that the system can maintain relatively low wear during long-term use, improving the lifespan and reliability of the equipment.

[0034] Furthermore, two liquid storage chambers 20 are fixedly installed on the bearing housing. The lower surface of the liquid storage chamber 20 is close to the application part 19. The outer wall of the liquid storage chamber 20 has multiple through holes, and capillary cotton 26 is fixedly installed in the through holes. One end of the capillary cotton 26 contacts the outer wall of the application part 19, and the other end contacts the liquid inside the liquid storage chamber 20. In this embodiment, please refer to... Figure 8 Through the liquid storage chamber 20 and the capillary cotton 26 in the through hole, the lubricating liquid can be evenly delivered to the coating part 19. The capillary cotton has an adsorption effect, which can maintain an appropriate amount of liquid, so that the coating part 19 is always adequately lubricated. This helps to reduce friction and wear between the coating part 19 and the friction surface, and extend the service life of the coating part. Since the coating part 19 is in contact with the capillary cotton 26 in the through hole and the liquid storage chamber 20, the coating part 19 can receive a continuous and stable liquid supply. This helps to maintain the wet state of the surface of the coating part 19, and ensures that the paint or lubricating oil can be evenly distributed on the coating part 19, thereby improving the coating effect and the quality of the coating.

[0035] Furthermore, the coating part 19 is made of silicone. Both ends of the coating part 19 are connected to the roll-up roller 25 and the hinge platform 31 respectively via adhesive. In this embodiment, silicone has excellent wear resistance, maintaining good durability under continuous friction and high-speed movement. This allows the coating part 19 to withstand friction and pressure for extended periods without wear, thus extending its service life. Moreover, silicone has good elasticity and flexibility, adapting to work surfaces of different shapes and sizes. This allows the coating part 19 to adhere to the roll-up roller 25 and the hinge platform 31, ensuring uniform pressure distribution during the coating process and improving the coating effect and quality. Connecting the coating part 19 to the roll-up roller 25 and the hinge platform 31 with adhesive provides good fixation and stability. This prevents the coating part 19 from loosening or falling off during movement, ensuring the continuity and stability of the coating process.

[0036] Furthermore, a torsion spring 33 is provided at the hinge point between the first connecting rod 24 and the bearing housing. The maximum torsion angle of the torsion spring is not less than forty-five degrees. In this embodiment, please refer to... Figure 8The torsion spring 33 is designed to better extend the applicator 19 for applicator application. The maximum torsion angle of the torsion spring 33 is not less than 45 degrees, which means that the torsion spring has a large elastic deformation capacity. When the movement between the first connecting rod 24 and the bearing seat changes, the torsion spring can adaptively torsion as needed, maintaining appropriate tension and elasticity. This helps to adjust and balance the force and angle of the connecting rod movement, providing a stable and smooth motion process. Moreover, by limiting the range of motion and providing appropriate elastic force, the torsion spring helps to reduce looseness and wobbling in the system, maintain a tight connection between the connecting rod and the bearing seat, and improve the accuracy and stability of the system.

[0037] Working principle: When using this high-precision PET hot pressing molding equipment, the feeding component and the discharging component work together to transport the material to the hot pressing position. Then, the hydraulic column 16 pushes the limiting plate 15 to drive the upper mold 27 to move downward. After reaching the preset position, the material is hot pressed. After the hot pressing is completed, the hydraulic column 16 lifts the discharging component to drive the material away from the hot pressing position. After the hot pressing is completed, in order to prevent the mold from sticking to the material during the next hot pressing, the coating component will apply an anti-stick agent to the mold surface to prevent the material from sticking.

[0038] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed directly based on existing technical knowledge without any doubt. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
