Description

Technical Field

[0001] This utility model relates to the field of protective film manufacturing technology, specifically to a multi-layer protective film hot pressing device that facilitates temperature adjustment. Background Technology

[0002] In the production and processing of multilayer protective films, hot pressing is a crucial step. Hot pressing involves placing the multilayer protective film under specific temperature and pressure conditions, causing the layers to bond tightly together, thus forming a composite film material with specific properties.

[0003] For example, a protective film hot pressing device with Chinese Patent Publication No. CN222223233U includes a support platform, an unwinding frame, and a winding frame. The unwinding frame is fixedly installed on the upper surface of one end of the support platform, and the winding frame is fixedly installed on the upper surface of the other end of the support platform. Side baffles are fixedly installed on the upper surface of the support platform near both sides. An adjusting frame is fixedly installed between the side baffles at the upper end. Support plates are fixedly installed on the upper surface of the support platform at the front and rear ends of the adjusting frame. A rotary motor is fixedly installed on one side surface of the support plate near the top and bottom. When foreign matter adheres to the surface of the hot pressing roller during operation, a scraper can be used to clean the foreign matter from the surface of the hot pressing roller. When it is necessary to adjust the tightness of the protective film, rotating the adjusting knob can control the adjusting roller to move up and down, thus adjusting the tightness of the protective film.

[0004] However, the aforementioned hot pressing equipment has shortcomings in temperature control, making it difficult to achieve precise and flexible temperature adjustment. This limits the quality and efficiency of hot pressing of multilayer protective films to some extent. Specifically, it typically uses fixed heating elements and simple temperature control methods, making it difficult to accurately adjust the temperature according to the different materials and thicknesses of multilayer protective films. During the hot pressing process, if the temperature is too high, it may cause the protective film to deform, burn, or degrade in performance; while if the temperature is too low, it may not be able to achieve sufficient bonding between the layers, affecting the overall performance of the composite film.

[0005] Therefore, in order to address the above problems, the applicant needs to design a multi-layer protective film hot pressing device that is easy to adjust the temperature to solve the problem. Utility Model Content

[0006] The purpose of this invention is to provide a multi-layer protective film hot pressing device that facilitates temperature adjustment, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer protective film hot pressing device for easy temperature adjustment, including a support platform. It also includes: a hot pressing mechanism set on a support platform, and the hot pressing mechanism is used for hot pressing a multi-layer protective film. The hot pressing mechanism includes a support plate fixedly connected to the support platform. An installation strip is fixedly set on the support plate, and a lower pressure plate is fixedly set above the installation strip. A slide rod is fixedly set on the support plate, and a fixing plate is fixedly set on the slide rod. A cylinder is fixedly set on the fixing plate, and an upper pressure component capable of adjusting the temperature is set at the output end of the cylinder. A support frame is fixedly connected to a support platform, and a support column is fixedly installed on the support frame. A guide roller is fixedly installed on the support column, and the guide roller is used to clamp multiple protective films.

[0008] Furthermore, the pressure assembly includes a connecting plate connected to the cylinder output end, and a connecting rod is fixedly mounted on the connecting plate. A mounting plate is fixedly mounted on the end of the connecting rod away from the connecting plate, and a heat-conducting plate is fixedly mounted on the mounting plate.

[0009] Through the above structural design, the modular design of the connecting plate, connecting rod, mounting plate and heat conduction plate enables the upper pressure assembly to form an independent temperature regulation unit.

[0010] Furthermore, a heating chamber is fixedly installed above the heat-conducting plate, and an electric heater is installed inside the heating chamber, and the electric heater is electrically connected to an external stepless controller.

[0011] Through the above structural design, an electric heater is integrated into the heating chamber and connected to a stepless controller to achieve continuous adjustment of the heating power.

[0012] Furthermore, a temperature sensor is embedded inside the heat-conducting plate, and both the temperature sensor and the electric heater are connected to an external stepless controller to form a closed-loop temperature control system. The stepless controller is configured to dynamically adjust the power output of the electric heater based on the real-time monitoring data of the temperature sensor.

[0013] Through the above structural design, a closed-loop control system is formed by a temperature sensor and an electric heater, enabling real-time monitoring and dynamic feedback adjustment of the heat-conducting plate temperature.

[0014] Furthermore, a guide sleeve is fixedly provided on the connecting plate, and the guide sleeve is slidably connected to the slide rod.

[0015] Through the above structural design, the sliding fit between the guide sleeve and the slide rod ensures that the upper pressure assembly maintains vertical stability during the lifting and lowering process.

[0016] Furthermore, the bottom surface of the heat-conducting plate is covered with a high-temperature resistant, non-stick coating, which is made of polytetrafluoroethylene and ceramic microparticles.

[0017] Through the above structural design, the non-stick coating composed of polytetrafluoroethylene and ceramic microparticles prevents the molten material of the protective film from sticking to the heat-conducting plate during high-temperature hot pressing.

[0018] Furthermore, a support frame is fixedly installed on the support frame, and an auxiliary roller is installed inside the support frame. The auxiliary roller cooperates with the guide roller to clamp the multi-layer protective film.

[0019] Through the above structural design, the coordinated clamping design of the auxiliary roller and the guide roller ensures that the multi-layer protective film remains flat and taut before entering the hot pressing mechanism.

[0020] Furthermore, a reinforcing column is fixedly installed below the support frame, and the end of the reinforcing column away from the support frame is fixedly connected to the support platform.

[0021] Through the above structural design, the reinforced column enhances the connection rigidity between the support frame and the support platform by using a triangular support structure.

[0022] Compared with the prior art, the beneficial effects of this utility model are: the multi-layer protective film hot pressing equipment with easy temperature adjustment precisely regulates the temperature of the heat-conducting plate through a closed-loop temperature control system, effectively avoiding the problem of the protective film burning due to overheating or insufficient bonding due to low temperature, and improving the hot pressing quality of multi-layer protective films of different materials or thicknesses. The specific details are as follows: When using this multi-layer protective film hot pressing equipment that facilitates temperature adjustment, the multi-layer protective film is flattened and clamped by guide rollers and auxiliary rollers and transported to the hot pressing area. The cylinder drives the upper pressing component to press vertically down along the slide bar, so that the heat-conducting plate and the lower pressing plate press the protective film together. At the same time, the temperature sensor embedded in the heat-conducting plate monitors the temperature in real time and feeds it back to the stepless controller. The controller dynamically adjusts the power output of the electric heater to achieve precise temperature control, and finally achieves high-quality hot pressing composite of protective films of different materials or thicknesses.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-4 As shown, this utility model discloses a multi-layer protective film hot pressing device for easy temperature adjustment, including a support platform 1 and a hot pressing mechanism 2 disposed on the support platform 1. The hot pressing mechanism 2 is used for hot pressing multi-layer protective films. The hot pressing mechanism 2 includes a support plate 20 fixedly connected to the support platform 1, an mounting strip 25 fixedly disposed on the support plate 20, a lower pressure plate 26 fixedly disposed above the mounting strip 25, a sliding rod 21 fixedly disposed on the support plate 20, a fixing plate 22 fixedly disposed on the sliding rod 21, a cylinder 23 fixedly disposed on the fixing plate 22, and an upper pressure component 24 capable of adjusting temperature disposed at the output end of the cylinder 23; a support frame 10 fixedly connected to the support platform 1, a support column 11 fixedly disposed on the support frame 10, a guide roller 12 fixedly disposed on the support column 11, and the guide roller 12 is used to clamp the multi-layer protective film.

[0027] The pressing assembly 24 includes a connecting plate 240 connected to the output end of the cylinder 23, and a connecting rod 241 is fixedly mounted on the connecting plate 240. A mounting plate 242 is fixedly mounted on the end of the connecting rod 241 away from the connecting plate 240, and a heat-conducting plate 243 is fixedly mounted on the mounting plate 242. Through the modular design of the connecting plate 240, the connecting rod 241, the mounting plate 242 and the heat-conducting plate 243, the pressing assembly 24 forms an independent temperature regulation unit, allowing the heat-conducting plate 243 to directly contact the protective film for heat transfer. At the same time, precise lifting and lowering control is achieved through the cylinder 23, ensuring the high efficiency of temperature transfer and the uniformity of pressure distribution during the hot pressing process.

[0028] A heating chamber 244 is fixedly installed above the heat-conducting plate 243. An electric heater 245 is installed inside the heating chamber 244 and is electrically connected to an external stepless controller. The electric heater 245 is integrated in the heating chamber 244 and connected to the stepless controller to realize continuous adjustment of the heating power. The output power can be adjusted in real time according to the material and thickness of different protective films to avoid the film material from burning due to excessive temperature or the interlayer bonding from insufficient temperature, thereby improving the adaptability of hot pressing process.

[0029] A temperature sensor is embedded inside the heat-conducting plate 243, and both the temperature sensor and the electric heater 245 are connected to an external stepless controller to form a closed-loop temperature control system. The stepless controller is configured to dynamically adjust the power output of the electric heater 245 based on the real-time monitoring data of the temperature sensor. By forming a closed-loop control system with the temperature sensor and the electric heater 245, the temperature of the heat-conducting plate 243 can be monitored in real time and dynamically adjusted based on feedback. This ensures that the hot pressing temperature strictly matches the process requirements, eliminates the risk of protective film deformation or performance degradation caused by temperature fluctuations, and significantly improves product yield.

[0030] A guide sleeve 246 is fixedly installed on the connecting plate 240, and the guide sleeve 246 is slidably connected to the slide rod 21. The sliding fit design of the guide sleeve 246 and the slide rod 21 ensures that the upper pressure assembly 24 maintains vertical stability during the lifting process, avoids the possible skewing or shaking when the cylinder 23 moves, ensures that the pressing surfaces of the heat-conducting plate 243 and the lower pressure plate 26 are always parallel, prevents local overheating or poor bonding due to uneven pressure, and ensures consistent hot pressing quality.

[0031] The bottom surface of the heat-conducting plate 243 is covered with a high-temperature resistant non-stick coating. The non-stick coating is made of polytetrafluoroethylene and ceramic microparticles. The non-stick coating made of polytetrafluoroethylene and ceramic microparticles is an existing coating material. It effectively solves the problem of the protective film molten material sticking to the heat-conducting plate 243 during high-temperature hot pressing. The coating can withstand repeated high-temperature impacts and reduces the frequency of downtime cleaning. It avoids the temperature transfer failure and film surface damage caused by film adhesion in traditional equipment and improves the continuous operation efficiency of the equipment.

[0032] A support frame 13 is fixedly installed on the support frame 10. An auxiliary roller 14 is installed inside the support frame 13. The auxiliary roller 14 cooperates with the guide roller 12 to clamp the multi-layer protective film. The cooperative clamping design of the auxiliary roller 14 and the guide roller 12 ensures that the multi-layer protective film remains flat and taut before entering the hot pressing mechanism 2. This eliminates the interference of film wrinkles or displacement on the temperature uniformity of the hot pressing area, ensures that heat penetrates evenly between the film layers, and avoids the local insufficient bonding strength caused by uneven film material from the source.

[0033] A reinforcing column 15 is fixedly installed below the support frame 10, and the end of the reinforcing column 15 away from the support frame 10 is fixedly connected to the support platform 1. The reinforcing column 15 strengthens the connection between the support frame 10 and the support platform 1 through a triangular support structure, effectively suppressing the impact of equipment vibration on the stability of the guide roller 12 and auxiliary roller 14 during hot pressing, preventing the film material transmission path from deviating, indirectly ensuring the stable operation of the temperature control system, and improving the overall equipment reliability.

[0034] Working principle: When using this multi-layer protective film hot pressing equipment that is easy to adjust the temperature, the multi-layer protective film is flattened and conveyed to the hot pressing area by the guide roller 12 and the auxiliary roller 14. The cylinder 23 drives the upper pressing component 24 to press vertically down along the slide bar 21, so that the heat-conducting plate 243 and the lower pressing plate 26 press the protective film together. At the same time, the temperature sensor embedded in the heat-conducting plate 243 monitors the temperature in real time and feeds it back to the stepless controller. The controller dynamically adjusts the power output of the electric heater 245 to achieve precise temperature control, and finally achieves high-quality hot pressing composite of protective films of different materials or thicknesses.

[0035] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
