Description

Technical Field

[0001] This utility model relates to the field of PE film production technology, and in particular to an adhesive applicator for repeatedly applying PE protective film. Background Technology

[0002] PE film, or polyethylene film, refers to films made from PE granules. PE films are moisture-proof and have low moisture permeability. Depending on the manufacturing method and control measures, polyethylene (PE) films can be made into products with different properties, such as low-density, medium-density, high-density polyethylene, and cross-linked polyethylene. Currently, some PE films require dip-coating equipment to coat their surface with adhesive during processing.

[0003] Existing technology provides an adhesive dipping device for processing PE protective film. This device includes a PE protective film, an adhesive tank, two adhesive-absorbing sponge wheels inside the adhesive tank, the PE protective film positioned between the two sponge wheels, and a rotating shaft fixed to the inner side of each sponge wheel. Two through holes are provided on opposite sides of the adhesive tank, allowing the rotating shafts to rotate within these holes. A drive assembly is located between the adhesive tank and the rotating shafts. A scraper is attached to the lower side of each sponge wheel, and a connecting plate is fixed to the upper side of each scraper. A shaft seat is fixed to the upper side of each connecting plate, and a fixed shaft is rotatably mounted inside each shaft seat. This invention, by incorporating an adhesive tank, adhesive-absorbing sponge wheels, rotating shafts, a scraper, connecting plate, shaft seat, fixed shaft, and an L-shaped hollow frame, provides dipping coating, automatic removal, automatic adjustment, and excess material control functions.

[0004] However, the device lacks a structure to clean impurities from the PE film surface before applying adhesive. As a result, dust, debris, and other impurities on the PE film surface can easily mix into the adhesive layer during the adhesive application process. This not only affects the uniformity and adhesion of the adhesive layer, but may also cause problems such as weak adhesion and air bubbles when the protective film is repeatedly pasted, thus reducing the quality and effectiveness of the PE protective film.

[0005] Therefore, it is necessary to provide an adhesive applicator that can repeatedly apply PE protective film to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides an adhesive applicator for repeatedly applying PE protective film, which solves the problem that the existing adhesive applicator lacks a structure for cleaning impurities on the PE film surface, resulting in a compromise in adhesive layer quality.

[0007] To solve the above-mentioned technical problems, this utility model provides an adhesive applicator for repeatedly applying PE protective film, comprising: Impregnation tank; A cleaning frame is fixedly installed at one end of the top of the impregnation tank; Two cleaning components are respectively disposed inside the top and bottom of the cleaning frame.

The device utilizes a cleaning assembly, a filtering assembly, and a blower in coordinated operation. During use, after the PE film enters the cleaning frame, cleaning brushes in the cleaning assemblies at the top and bottom of the frame clean the upper and lower surfaces of the film. When the blower is activated, the suction force draws the cleaned impurities through the through-hole into the air collection frame, and then through the first air pipe to the filtering assembly.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] First Embodiment Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an adhesive applicator for reusable PE protective film provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the cleaning frame; Figure 3 for Figure 1 The diagram shows a partial cross-sectional view of the cleaning frame. Figure 4 for Figure 2 The diagram shows a cross-sectional view of the filter assembly. A coating device for reusable PE protective film includes: an impregnation tank 1; Cleaning frame 3, the cleaning frame 3 is fixedly installed at one end of the top of the impregnation tank 1; Two cleaning components 4 are respectively disposed inside the top and bottom of the cleaning frame 3. Each of the two cleaning components 4 includes an air collection frame 41. The two air collection frames 41 are respectively fixedly installed inside the top and bottom of the cleaning frame 3. A cleaning brush 42 is fixedly installed on the opposite side of each of the two air collection frames 41. Multiple through holes 43 are provided on both sides of the cleaning brush 42. The multiple through holes 43 are opened on the side of the air collection frame 41. The first air pipe 5, with its two input ends fixedly installed at the output ends of the two air collection frames 41 respectively; Filter assembly 6, wherein the filter assembly 6 is disposed at the output end of the first air tube 5; The exhaust fan 7 is located at the output end of the filter assembly 6.

[0019] Multiple through holes 43 are evenly opened on the top of the air collection frame 41, so that the dust swept down can smoothly enter the interior of the air collection frame 41 and then be transported to the interior of the filter assembly 6 through the first air pipe 5.

[0020] The filter assembly 6 includes a mounting frame 61, which is fixedly mounted on one end of the cleaning frame 3. A collection frame 62 is provided at the bottom of the inner side of the mounting frame 61. A filter plate 63 is fixedly mounted on the top of the collection frame 62. A sealing plate 64 is fixedly mounted on the top of the filter plate 63. The bottom of the sealing plate 64 abuts against the top of the mounting frame 61. A handle 65 is fixedly mounted on the top of the sealing plate 64.

[0021] The filter plate 63 is attached to the inner side of the mounting frame 61 near the exhaust fan 7. When in use, after the gas enters the inner side of the mounting frame 61, it can be filtered by the filter plate 63. At the same time, the impurities that fall off will be collected on the inner side of the collection frame 62. When it is necessary to clean the impurities later, the handle 65 can be lifted upwards to move the sealing plate 64 and the filter plate 63 upwards, thereby removing the filter plate 63 and the collection frame 62 from the inner side of the mounting frame 61. At this time, the user can clean the impurities.

[0022] The input end of the mounting frame 61 and the output end of the first air pipe 5 are fixedly installed, and the output end of the mounting frame 61 and the input end of the exhaust fan 7 are fixedly installed.

[0023] The inner side of the input end of the cleaning frame 3 is rotatably connected to a first pressure roller 32 and a second pressure roller 33, which are arranged vertically. The inner side of the output end of the cleaning frame 3 is rotatably connected to a second guide roller 31.

[0024] The first pressure roller 32 and the second pressure roller 33 are configured to press the PE film, so that the PE film moves between the two cleaning brushes 42.

[0025] The inner side of the impregnation tank 1 is rotatably connected to a plurality of first guide rollers 11, and the inner side of the impregnation tank 1 is also fixedly installed with a scraping assembly 2.

[0026] The adhesive scraping assembly 2 includes a frame, two drive telescopic components, and two scrapers. In use, the PE protective film enters from the bottom of the frame and exits from the top of the frame. At this time, the two scrapers are located on both sides of the PE protective film to scrape off the adhesive on the PE protective film. When it is necessary to adjust the thickness of the adhesive on the PE protective film, the drive telescopic components can be activated to adjust the position of the two scrapers, thereby adjusting the thickness of the adhesive on the PE protective film.

[0027] The working principle of the adhesive applicator for reusable PE protective film provided by this utility model is as follows: When in use, the PE film to be coated is passed through the middle of the first pressure roller 32 and the second pressure roller 33, and then the PE film is placed in the middle of the two cleaning components 4. After that, it is guided to the bottom of the impregnation tank 1 by the second guide roller 31, and the PE film passes through the bottom of the two first guide rollers 11 and then moves out from the inside of the scraping component 2. When the PE film passes through the two cleaning components 4, the two cleaning brushes 42 can clean the top and bottom of the PE film respectively, and at the same time, the exhaust fan 7 is started, so that the exhaust fan 7 draws the cleaned impurities into the interior of the two air collection frames 41 through the through hole 43, and then transports them to the inner side of the mounting frame 61 through the first air pipe 5. After that, the impurities are filtered by the filter plate 63, and then the air is discharged by the exhaust fan 7. In this way, dust, debris and other impurities can be effectively avoided on the adhesive surface of the PE protective film, keeping the adhesive surface clean and flat, thereby ensuring that the subsequent adhesive layer can be evenly adhered and tightly bonded to the film, thus improving the effect of subsequent repeated adhesion of the PE protective film.

[0028] Compared with related technologies, the adhesive applicator for reusable PE protective film provided by this utility model has the following advantages: The cleaning assembly 4, the filter assembly 6, and the exhaust fan 7 work together to ensure that when the PE film enters the cleaning frame 3, the cleaning brushes 42 in the cleaning assembly 4 located at the top and bottom of the cleaning frame 3 can clean the upper and lower surfaces of the PE film respectively. After the exhaust fan 7 is started, the suction force generated causes the cleaned impurities to enter the air collection frame 41 through the through hole 43, and then be transported to the filter assembly 6 through the first air pipe 5. In this way, dust, debris and other impurities on the surface of the PE film can be effectively removed before the adhesive is applied, preventing impurities from mixing into the adhesive layer, ensuring the uniformity and adhesion of the adhesive layer, thereby improving the firmness of the PE protective film when it is repeatedly pasted, reducing the generation of air bubbles, and improving the quality and performance of the PE protective film.

[0029] Second Embodiment Please refer to the following: Figure 5 , Figure 6 and Figure 7 Based on the first embodiment of this application which provides an adhesive applicator for reusable PE protective film, the second embodiment of this application proposes another adhesive applicator for reusable PE protective film. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0030] Specifically, the second embodiment of this application provides a coating device for reusable PE protective film, which differs in that, in this coating device for reusable PE protective film, an oven 9 is fixedly installed at the other end of the top of the impregnation tank 1, a third guide roller 91 is rotatably connected to the inner side of the input end of the oven 9, and heating components 92 are provided at the top and bottom of the inner side of the output end of the oven 9. Each of the two heating components 92 includes an air guide frame 921, and the two air guide frames 921 are respectively fixedly installed at the top and bottom of the inner side of the oven 9. An air outlet frame 922 is fixedly installed on the opposite side of each of the two air guide frames 921, and a heating wire 923 is fixedly installed on the inner side of each of the two air outlet frames 922.

[0031] The output end of the exhaust fan 7 is fixedly installed with a second air pipe 8, and the output end of the second air pipe 8 is fixedly installed with a diverter frame 81. The two output ends of the diverter frame 81 are respectively fixedly installed at the input ends of the two air guide frames 921.

[0032] The working principle of the adhesive applicator for reusable PE protective film provided by this utility model is as follows: When in use, the PE film coming out from inside the adhesive scraper assembly 2 is placed on the third guide roller 91 and then pulled out from the other end of the oven 9. At this time, the gas discharged by the exhaust fan 7 will be transported through the second air pipe 8 to the inside of the diversion frame 81, and then to the inside of the air guide frame 921, and then discharged through the air outlet frame 922. At this time, the heating wire 923 will heat the gas, so that the heated gas is blown onto the front and back of the PE film, thereby drying the adhesive on the PE film.

[0033] Compared with related technologies, the adhesive applicator for reusable PE protective film provided by this utility model has the following advantages: The oven 9, the third guide roller 91, and the heating component 92 work together to ensure that the coated PE film enters the oven 9 during use. The gas discharged from the exhaust fan 7 enters the air guide frame 921 through the second air pipe 8 and the diversion frame 81, and is then discharged through the air outlet frame 922. At the same time, the heating wire 923 heats the gas. The heated gas blows on both sides of the PE film to dry the adhesive layer. In this way, the gas discharged from the exhaust fan 7 is recycled and converted into a drying heat source by the heating component 92, which reduces heat loss and improves energy utilization. At the same time, the symmetrical heating structure ensures that the PE film is heated evenly, accelerates the curing of the adhesive, shortens the drying time, and improves production efficiency.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
