Description

Technical Field

[0001] This utility model relates to the field of filter element processing technology, and in particular to a filter element coating device. Background Technology

[0002] After processing, filter cartridges are typically covered with a thin film using a heat shrink wrapping machine. This shrink film, wrapped around the product or packaging, is then heated to shrink and tightly encase the product or packaging, fully showcasing its appearance, improving its marketability, and increasing its aesthetic appeal and perceived value.

[0003] In existing technologies, the device cannot be adjusted according to the size and thickness of the filter element. Only a fixed device can be used for membrane coating. Membrane replacement is difficult, and it is difficult to accurately cut filter elements of different thicknesses. Manual cutting is inefficient and increases costs. Utility Model Content

[0010] According to the filter cartridge coating device, a curtain is fixedly connected to the side of the heat shrink coating machine, and steel rollers are evenly arranged inside the roller conveyor to ensure that the coated filter cartridge can enter the heat shrink coating machine and to prevent the blades from damaging the rollers.

[0011] According to the filter cartridge coating device, the first and second conveyor rollers have smooth surfaces and are arranged in parallel to ensure that the first and second conveyor rollers will not damage the heat shrink film and to ensure stable operation during film feeding.

The outside of the screw 23 is threaded into the inside of the roller conveyor 1. By loosening the bolts on conveyor roller 7 and conveyor roller 25, the fixing rod 26 and fixing rod 27 are separated from conveyor roller 7 and conveyor roller 25. Loosening the screw 23... The lifting frame 3 can slide to the right, and the heat shrink film is rolled onto the second conveyor roller 25. Then, the first conveyor roller 7 and the second conveyor roller 25 are bolted to the first fixing rod 26 and the second fixing rod 27 in the same way. The second motor 17 and the third motor 18 are opened at the same time.

[0027] Two wooden boards 8 are fixedly connected to the upper surface of the roller conveyor 1. Each wooden board 8 has a groove 14 inside. A threaded rod 16 is rotatably connected inside one of the wooden boards 8. A slider 9 is threadedly connected to the outside of the threaded rod 16. The outside of the slider 9 is slidably connected to the inside of one of the grooves 14. A motor 10 is fixedly connected to the upper surface of the wooden board 8.

The filter element moves forward with the operation of the roller conveyor 1. The heating rod inside the cutter 15 can preheat the cutter 15. The signal of one infrared sensor 11 is transmitted to the motor 10. When the presence of the filter element is detected, the motor 10 is operated, causing the threaded rod 16 to rotate, thereby driving the cutter 15 to slide up and down. The signal of the other infrared sensor 11 is transmitted to the roller conveyor 1. After the presence of the filter element is detected, the conveying speed of the roller conveyor 1 is slowed down, so as to adapt to different membrane materials of the filter element and improve the appearance quality of the filter element.

[0028] A heat shrink wrapping machine 13 is fixedly connected to the upper surface of the roller conveyor 1. A heat shrink tube 19 is fixedly connected inside the heat shrink wrapping machine 13.

[0031] A curtain is fixedly connected to the side of the heat shrink wrapping machine 13, and steel rollers are evenly arranged inside the roller conveyor 1, which allows the filter element wrapped with film to smoothly enter the heat shrink wrapping machine 13.

[0032] The surfaces of conveyor roller 7 and conveyor roller 25 are smooth, and they are arranged in parallel to prevent them from damaging the heat shrink film.

[0033] The infrared sensors 11 are symmetrically arranged, and the lifting frame 3 is made of aluminum alloy, which has the advantages of being lightweight, high-strength, and having good corrosion resistance.

[0034] The sides of the heat shrink wrapping machine 13 are made of transparent glass, and the first fixing rod 26 and the second fixing rod 27 are symmetrically arranged to better observe the heat shrinking process.

[0035] Working principle: By loosening the bolts on conveyor rollers 7 and 25, fixing rods 26 and 27 are separated from conveyor rollers 7 and 25. Loosening screw 23 allows the lifting frame 3 to slide to the right, allowing the heat-shrink film to be rolled onto conveyor roller 25. Conveying conveyor rollers 7 and 25 to fixing rods 26 and 27 is done in the same way. Simultaneously, motors 17 and 18 are activated, pulling the heat-shrink film and rolling it onto conveyor roller 7. Comparing the size and thickness of the filter element, cylinder 6 is activated, causing slider 4 to slide up and down in chute 5, placing the filter element. The filter element moves with the roller conveyor 1. The blade 15 moves forward, and the heating rod inside the blade 15 can preheat the blade 15. The signal of one infrared sensor 11 is transmitted to the motor 10. When the presence of the filter element is detected, the motor 10 is activated, causing the threaded rod 16 to rotate, thereby driving the blade 15 to slide up and down. The signal of the other infrared sensor 11 is transmitted to the roller conveyor 1. After the presence of the filter element is detected, the conveying speed of the roller conveyor 1 is slowed down, so as to adapt to different membrane materials of the filter element and improve the appearance quality of the filter element. After the filter element is cut, it is conveyed by the roller conveyor 1 to the heat shrink wrapping machine 13. The heat shrink wrapping machine 13 heat shrinks the membrane onto the filter element.
