Description

Technical Field

[0001] This utility model relates to the technical field of PVC film heat coating mechanism, specifically a heat coating mechanism for the surface of PVC film substrate. Background Technology

[0002] PVC film is a thin film made of polyvinyl chloride, with a variety of properties and uses. PVC film is generally slightly yellow and translucent with a glossy appearance. Its transparency is better than that of polyethylene and polypropylene, but worse than that of polystyrene.

[0003] A heat-coating mechanism is required in the production of PVC film. Chinese utility model patent CN214646002U discloses a heat-coating mechanism for the surface of PVC film substrate. The mechanism includes a frame, on which are arranged a film substrate feeding roll, a heat-coating feeding roll, a coating device for bonding the heat-coating film to the surface of the film substrate, and a finished film receiving roll. Between the feeding roll and the coating device, there are corona rollers and a dust-removing roller for removing dust from the surface of the film substrate. The heat-coated film produced by this device does not require special adhesives and is directly heat-fused to the surface to be coated, resulting in low production costs. The finished product obtained by this utility model heat-coating mechanism is a PVC film coated with high-gloss PET. Compared with ordinary pure PVC film, it has advantages such as high gloss, waterproof, stain resistance, and scratch resistance. The coated surface is smooth, high-gloss, and transparent, and is beautiful and elegant.

[0004] This utility model directly applies heat-melt bonding to the surface to be coated, resulting in low production costs. However, existing heat-coating mechanisms are not suitable for plastic films of different thicknesses and are not conducive to heat dissipation. This leads to the need for frequent equipment changes or parameter adjustments during the production process to adapt to the coating requirements of plastic films of different thicknesses. Furthermore, it cannot accelerate the cooling and forming speed of the plastic film, thus reducing production efficiency. Therefore, a heat-coating mechanism for PVC film substrates is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a thermal lamination mechanism for PVC film substrates, which has advantages such as applicability to substrates of different thicknesses and easy heat dissipation. It solves the problems of existing thermal lamination mechanisms being unable to be applied to plastic films of different thicknesses, and being inconvenient to dissipate heat, which leads to the need for frequent equipment changes or parameter adjustments during the production process to adapt to the lamination requirements of plastic films of different thicknesses, and also fails to accelerate the cooling and forming speed of plastic films, thus reducing production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat-coating mechanism for the surface of PVC film substrate includes a frame, wherein a heat-coating component suitable for substrates of different thicknesses and easy to dissipate heat is provided inside the frame.

[0008] The thermal laminating assembly includes a hydraulic cylinder fixedly connected to the bottom wall of the machine frame.

A temperature sensor is fixedly connected to the outer surface of the hot press roller. A cutting assembly for quickly cutting the substrate is provided on the outside of the machine frame.

[0009] Furthermore, the cutting assembly includes a fixing frame fixedly connected to the front and back of the machine frame. A drive motor is fixedly connected to the left side of the fixing frame. A lead screw is fixedly connected to the output shaft of the drive motor. A threaded block is threadedly connected to the outer surface of the lead screw. A cutting blade is fixedly installed at the bottom of the threaded block.

[0010] Furthermore, a positioning rod is fixedly connected to the inner side of the fixing frame, and the threaded block is slidably connected to the positioning rod.

[0011] Furthermore, fixed posts are fixedly connected to the bottom of the mounting frame around its perimeter, and sliding sleeves are fixedly connected to the left and right sides of the electric conveyor belt, with the fixed posts and sliding sleeves slidably connected.

[0012] Furthermore, a heat-resistant metal mesh is provided between the fan and the air heating pipe, and ventilation openings are provided on the left and right sides of the mounting cover.

[0016] Compared with the prior art, the present invention provides a heat-coating mechanism for the surface of PVC film substrate, which has the following advantages:

[0017] 1. This heat-coating mechanism for PVC film substrates, by setting up heat-coating components, allows an electric conveyor belt to continuously transport the plastic film, and a hydraulic cylinder to drive the electric conveyor belt to move vertically upwards, thereby making the transported plastic film adhere tightly to the heat-pressing rollers and adjusting the distance between the plastic film and the heat-pressing rollers to meet the coating requirements of plastic films of different thicknesses. At this time, an air heating pipe can continuously heat the air, and a fan can blow the hot air onto the heat-pressing rollers, thereby heating the heat-pressing rollers to heat and coat the plastic film. During this process, a temperature sensor can monitor the temperature of the heat-pressing rollers in real time to prevent the plastic film from being damaged by excessive heat. At the same time, after the air heating pipe is turned off, the fan can continue to blow air onto the plastic film, thereby accelerating the cooling and forming speed of the plastic film and improving production efficiency.

[0018] 2. The heat-coating mechanism for the surface of PVC film substrate is equipped with a cutting component. The drive motor can drive the lead screw to rotate continuously clockwise or counterclockwise, thereby causing the threaded block to drive the cutting blade to move laterally and reciprocate, so as to quickly cut the plastic film after heat-coating.

[0024] Please see Figures 1 to 3This embodiment describes a heat-coating mechanism for PVC film substrates, comprising a frame 1. Inside the frame 1 is a heat-coating assembly suitable for substrates of varying thicknesses and designed for easy heat dissipation. The heat-coating assembly includes a hydraulic cylinder 2 fixedly connected to the bottom wall of the frame 1. An electric conveyor belt 3 is fixedly connected to the output shaft of the hydraulic cylinder 2. A mounting frame 4 is fixedly connected to the inner side of the frame 1. A mounting cover 5 is fixedly connected to the top of the mounting frame 4. A fan 6 is fixedly connected to the inner side of the mounting cover 5. Five air heating pipes 7 are fixedly connected to the inner side of the mounting frame 4. A hot press roller 8 is rotatably mounted at the bottom of the mounting frame 4. A temperature sensor 9 is fixedly connected to the outer surface of the hot press roller 8. A cutting assembly for quickly slicing the substrate is located outside the frame 1. The electric conveyor belt 3 continuously transports the plastic film. The hydraulic cylinder 2 drives the electric conveyor belt 3 to move vertically upwards, thereby ensuring the transported plastic film adheres tightly to the hot press roller 8 and adjusting the distance between the plastic film and the hot press roller 8 to accommodate coating requirements of different plastic film thicknesses.

[0025] At this time, the air heating tube 7 can continuously heat the air, and the fan 6 can blow the hot air onto the hot press roller 8, thereby heating the hot press roller 8 to hot press the plastic film. During this process, the temperature sensor 9 can monitor the temperature of the hot press roller 8 in real time to prevent the plastic film from being damaged by excessive heat. At the same time, after the air heating tube 7 is turned off, the fan 6 can continue to blow air onto the plastic film, thereby accelerating the cooling and forming speed of the plastic film and improving production efficiency.

[0026] In this embodiment, the cutting assembly includes a fixed frame 10 fixedly connected to the front and back of the machine frame 1. A drive motor 11 is fixedly connected to the left side of the fixed frame 10. A lead screw 12 is fixedly connected to the output shaft of the drive motor 11. A threaded block 13 is threadedly connected to the outer surface of the lead screw 12. A cutting blade 14 is fixedly installed at the bottom of the threaded block 13. The drive motor 11 can drive the lead screw 12 to rotate continuously clockwise or counterclockwise, thereby causing the threaded block 13 to drive the cutting blade 14 to move laterally and reciprocally, so as to quickly cut the plastic film after hot-pressing and lamination.

[0027] It should be noted that a positioning rod 15 is fixedly connected to the inner side of the fixing frame 10, and the threaded block 13 is slidably connected to the positioning rod 15. The positioning rod 15 achieves the effect of limiting the threaded block 13.

[0028] Specifically, fixed posts 16 are fixedly connected to the bottom of the mounting frame 4, and sliding sleeves 17 are fixedly connected to the left and right sides of the electric conveyor belt 3. The fixed posts 16 and sliding sleeves 17 are slidably connected, and the fixed posts 16 and sliding sleeves 17 achieve the effect of improving the lifting stability of the electric conveyor belt 3.

[0029] It should be noted that a heat-resistant metal mesh 18 is provided between the fan 6 and the air heating pipe 7, and ventilation openings are provided on the left and right sides of the mounting cover 5. The heat-resistant metal mesh 18 can prevent the fan 6 from being affected by the heat generated by the air heating pipe 7.

[0031] Specifically, a movable plate 19 is fixedly connected to the bottom of the body frame 1, and universal wheels are rotatably connected around the bottom of the movable plate 19, so that the movable plate 19 can facilitate the movement of the body frame 1.

[0032] It should be noted that slide rails 20 are provided on both the left and right sides of the top of the movable plate 19, and a waste bin 21 is slidably connected to the inner side of the slide rail 20. The waste bin 21 can store heat-coated waste.

[0033] The working principle of the above embodiments is as follows:

[0034] During use, the electric conveyor belt 3 continuously conveys the plastic film, and the hydraulic cylinder 2 drives the electric conveyor belt 3 to move vertically upward, so that the conveyed plastic film is pressed tightly against the hot press roller 8, and the distance between the plastic film and the hot press roller 8 is adjusted to meet the coating requirements of plastic films of different thicknesses. At this time, the air heating pipe 7 continuously heats the air, and the fan 6 blows the hot air onto the hot press roller 8, thereby heating the hot press roller 8 to hot press the plastic film. During this process, the temperature sensor 9 can monitor the temperature of the hot press roller 8 in real time to prevent the plastic film from being damaged by excessive heat. At the same time, after the air heating pipe 7 is turned off, the fan 6 can continue to blow air onto the plastic film, thereby accelerating the cooling and forming speed of the plastic film.
