Description

Technical Field

[0001] This utility model relates to the field of release film technology, specifically a release film production coating device. Background Technology

[0002] Release film is a thin film material with low adhesion or release properties on its surface. It is usually made of PET as the base material and coated with release agents such as silicone oil and fluorine. Its core function is to assist bonding and easy peeling, making it convenient for processing, transportation and storage. When using it, you only need to peel the release film off the adhesive material to achieve subsequent bonding. After peeling, there will be no adhesive residue and no damage to the performance of the adhesive material.

[0003] Coating equipment is used in the production of release films, tapes, films and other products to uniformly coat functional substances such as adhesives and coatings onto the surface of a substrate. The core structure usually includes an unwinding mechanism, a coating mechanism and a scraper assembly to achieve a uniform coating effect on the substrate surface and meet the needs of different industries for product adhesion, thickness and flatness.

[0004] In existing coating equipment, after the doctor blade scrapes off the excess adhesive from the coating roller during the production of release film, most of the adhesive is discarded, resulting in considerable waste of adhesive. Therefore, a new coating equipment for release film production is proposed to address the above problem. Utility Model Content

The excess adhesive scraped off by the scraper falls into the collection box through the trough for temporary storage, and then flows into the filter box to filter and remove impurities. After the clean adhesive is filtered and removed, it is pumped back to the storage tank for reuse, which can further improve the utilization rate of adhesive and reduce the direct waste caused by the lack of recycling channels for excess adhesive scraped off by the scraper, thus significantly improving the utilization rate of adhesive raw materials.

[0008] Preferably, the top of the glue storage tank is provided with a shielding groove; a locking rod is fixedly connected to the side wall of the shielding groove; the locking rod is located on the side wall of the glue storage tank; a handle is fixedly connected to the top of the locking rod; by removing the used shielding groove and then placing a new shielding groove into the glue storage tank, the glue can be replaced quickly, greatly simplifying the operation process and reducing the need to repeatedly clean the residual glue inside the glue storage tank after the glue is used up, and then slowly inject new glue.

[0009] Preferably, a drying box is fixedly connected to the top of the support plate; a heating rod is fixedly connected to the middle of the drying box; a heat insulation plate is fixedly connected to the top of the support plate; the heat insulation plate is positioned between the drying box and the glue roller; the heating rod can dry the adhesive on the surface of the coated release film, accelerate the curing of the adhesive, and enable the release film to quickly reach a rollable state, reducing waiting time in the production process, and further increasing the stability of the adhesive inside the glue storage tank in conjunction with the heat insulation plate.

[0010] Preferably, an air pump is fixedly connected to the side wall of the heat insulation plate; an air jet is fixedly connected to the side wall of the heat insulation plate; the air pump is connected to the air jet; the air jet is inclined; the airflow ejected through the air jet can directly act on the adhesive on the surface of the release film, remove moisture, and form a double drying with the heat of the heating rod, which greatly shortens the drying time of the adhesive and improves the production efficiency of the release film.

[0011] Preferably, a sealing gasket is fixed to the side wall of the collection box; the sealing gasket is located on the side of the push plate; by covering the gap between the push plate and the side of the collection box with the sealing gasket, the gap caused by the sliding connection between the collection box and the push plate can be reduced, thus reducing glue leakage, reducing glue waste, and improving the utilization rate of raw materials.

[0012] The advantages of this utility model are: 1. The release film coating device of this utility model, when the rubber roller rotates, the scraper slides and cooperates with the rubber roller to scrape off excess adhesive on the surface of the rubber roller, ensuring uniform adhesive thickness on the surface of the rubber roller and ensuring the quality of release film coating.

[0013] 2. The release film production coating device of this utility model can drive the push plate to slide along the inner wall of the collection box by applying a pushing force to the push rod, actively pushing the adhesive inside the collection box to the inlet of the guide tube, which can effectively clean the residual adhesive inside the collection box, reduce the adhesive deposition at the bottom or side wall of the collection box, and further send the excess adhesive into the filter box for filtration, thereby improving the overall recycling rate of adhesive.

[0017] 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 scope of protection of the present utility model.

[0018] Specific implementation examples are given below.

[0019] like Figures 1 to 5 As shown in the embodiment of this utility model, a release film production coating device includes a workbench 1; a support plate 11 is fixedly connected to the top of the workbench 1; a glue storage tank 12 is fixedly connected to the top of the support plate 11; a glue roller 13 is rotatably connected to the side wall of the workbench 1; a fixing plate 14 is fixedly connected to the top of the support plate 11; the fixing plate 14 is located on one side of the glue roller 13; a scraper 15 is fixedly connected to the side wall of the fixing plate 14; the scraper 15 is slidably connected to the glue roller 13; and a collection box 16 is fixedly connected to the bottom end of the fixing plate 14. A guide pipe 17 is fixedly connected to the side wall of the collection box 16; a filter box 18 is fixedly connected to the side wall of the support plate 11; the guide pipe 17 is connected to the filter box 18; a material pump 19 is fixedly connected to the side wall of the support plate 11; during operation, the adhesive is added into the adhesive storage tank 12, and then the diaphragm pump inside the adhesive storage tank 12 is started, allowing the adhesive to flow out from the bottom of the adhesive storage tank 12 and then flow to the surface of the adhesive roller 13. The adhesive roller 13 then rotates, and the unwinding device is started, allowing the release film to be coated to pass through the channel in the middle of the support plate 11, so that the release film adheres to the surface of the adhesive roller 13. The mixture is then coated with dye and connected to a winding device to complete the coating process. As the running roller 13 rotates, excess adhesive on its surface comes into contact with the doctor blade 15. The doctor blade 15 scrapes the excess adhesive, causing it to fall from the groove in the middle of the doctor blade 15 into the collection box 16. The collection box 16 stores the excess adhesive, which then flows into the guide pipe 17 and into the filter box 18. The double-layer filtration of the filter box 18 filters out the excess adhesive. In conjunction with the feed pump 19, the adhesive inside the filter box 18 is extracted and returned to the adhesive storage tank. Inside 12; as the rubber roller 13 rotates, the scraper 15 slides and engages with the rubber roller 13, scraping off excess adhesive from the surface of the rubber roller 13, ensuring uniform adhesive thickness on the surface of the rubber roller 13, and ensuring the quality of the release film coating. The excess adhesive scraped off by the scraper 15 falls into the collection box 16 through the trough for temporary storage, and then flows into the filter box 18 to filter and remove impurities. After the clean adhesive is pumped back to the storage tank 12 for reuse, the utilization rate of adhesive can be further improved, and the direct waste caused by the lack of a recycling channel for the excess adhesive scraped off by the scraper 15 can be reduced, significantly improving the utilization rate of adhesive raw materials.

[0020] like Figure 2 and Figure 4As shown, a push plate 2 is slidably connected to the side wall of the collection box 16; a horizontal plate 21 is fixedly connected to the side wall of the push plate 2; the horizontal plate 21 is slidably connected to the side wall of the support plate 11; a push rod 22 is fixedly connected to the side wall of the push plate 2; the push rod 22 is slidably connected to the side wall of the support plate 11; during operation, when the adhesive is inside the collection box 16, a pushing force can be applied to the push rod 22, and then the push plate 2 slides on the inner side wall of the collection box 16, pushing the adhesive inside the collection box 16 towards the guide tube 17, and the horizontal plate 21. The top of the push plate 2 can be covered so that when the push plate 2 is pushed, the adhesive will not be carried out by the pull plate 2 when it is pulled back. By applying a pushing force to the push rod 22, the push plate 2 can be driven to slide along the inner side wall of the collection box 16, actively pushing the adhesive inside the collection box 16 to the inlet of the guide tube 17. This can effectively clean the residual adhesive inside the collection box 16, reduce the adhesive deposition at the bottom or side wall of the collection box 16, and further allow the excess adhesive to be sent into the filter box 18 for filtration, thereby improving the overall recycling rate of the adhesive.

[0021] like Figure 2 As shown, a shielding groove 3 is provided at the top of the glue storage tank 12; a locking rod 31 is fixedly connected to the side wall of the shielding groove 3; the locking rod 31 is located on the side wall of the glue storage tank 12; a handle 32 is fixedly connected to the top of the locking rod 31; during operation, when the glue inside the glue storage tank 12 needs to be cleaned after the glue has been used, simply remove the shielding groove 3 from the inside of the glue storage tank 12, put a new shielding groove 3 into the inside of the glue storage tank 12, and then lock the locking rod 31 on the side of the glue storage tank 12 to replace the glue inside the glue storage tank 12; by removing the used shielding groove 3 and then putting a new shielding groove 3 into the glue storage tank 12, the glue replacement can be completed quickly, greatly simplifying the operation process and reducing the need to repeatedly clean the residual glue inside the glue storage tank 12 after the glue has been used, and then slowly inject new glue.

[0022] like Figures 4 to 5 As shown, a drying chamber 4 is fixedly connected to the top of the support plate 11; a heating rod 41 is fixedly connected to the middle of the drying chamber 4; a heat insulation plate 42 is fixedly connected to the top of the support plate 11; the heat insulation plate 42 is positioned between the drying chamber 4 and the glue roller 13. During operation, after the release film comes into contact with the glue roller 13 for coating, the release film will move towards the drying chamber 4 due to the traction of the winding package. The heating rod 41 can dry the adhesive on the surface of the release film, and the heat insulation plate 42 can block the temperature emitted by the heating rod 41, so that the temperature emitted by the heating rod 41 is away from the side of the glue storage tank 12. The heating rod 41 can dry the adhesive on the surface of the coated release film, accelerate the curing of the adhesive, and make the release film quickly reach the rewindable state, reducing the waiting time in the production process. In conjunction with the heat insulation plate 42, it further increases the stability of the adhesive inside the glue storage tank 12.

[0023] like Figure 5As shown, an air pump 5 is fixedly connected to the side wall of the heat insulation plate 42; an air jet 51 is fixedly connected to the side wall of the heat insulation plate 42; the air pump 5 is connected to the air jet 51; the air jet 51 is inclined; during operation, when the heating rod 41 is drying the release film, the air pump 5 can also be activated, and then the air jet 51 sprays out airflow, which can blow the adhesive on the surface of the release film, so that the adhesive on the surface of the release film dries faster. The inclined setting of the air jet 51, in conjunction with the heat of the heating rod 41, makes the inclined airflow continuously dry the adhesive on the surface of the release film; the airflow sprayed through the air jet 51 can directly act on the adhesive on the surface of the release film, remove moisture, and form a double drying with the heat of the heating rod 41, which greatly shortens the adhesive drying time and improves the production efficiency of the release film.

[0024] like Figure 1 and Figure 4 As shown, a sealing gasket 6 is fixed to the side wall of the collection box 16; the sealing gasket 6 is located on the side of the push plate 2; during operation, the sealing gasket 6 can wrap the gap between the push plate 2 and the side of the collection box 16, so that the adhesive will not flow out from the side due to the push of the push plate 2; by wrapping the gap between the push plate 2 and the side of the collection box 16 with the sealing gasket 6, the gap caused by the sliding connection between the collection box 16 and the push plate 2 can be reduced, which would cause the adhesive to leak out, reduce adhesive waste, and improve the utilization rate of raw materials.

[0025] Working principle: Adhesive is added to the storage tank 12, and then the diaphragm pump inside the storage tank 12 is started. The adhesive flows out from the bottom of the storage tank 12 and then flows to the surface of the roller 13. The roller 13 then rotates, and the unwinding device is started, allowing the release film to be coated to pass through the channel in the middle of the support plate 11, so that the release film adheres to the surface of the roller 13 for coating. Then, the winding device is connected to complete the coating process. When the roller 13 rotates, excess adhesive on its surface comes into contact with the doctor blade 15, which scrapes away the excess adhesive from the groove in the middle of the doctor blade 15. The glue falls into the collection box 16, where it stores excess glue. The glue inside the collection box 16 flows into the guide tube 17 and then into the filter box 18. The double-layer filter of the filter box 18 filters out excess glue. Working in conjunction with the feed pump 19, the glue inside the filter box 18 is extracted and returned to the glue storage tank 12. While the glue is inside the collection box 16, it can also apply a pushing force to the push rod 22. Subsequently, the push plate 2 slides along the inner wall of the collection box 16, pushing the glue inside the collection box 16 towards the guide tube 17. The horizontal plate 21 can cover the top of the push plate 2, allowing... When the pusher plate 2 is pushed, the adhesive will not be carried out by the puller plate 2. After the adhesive in the storage tank 12 is used up, when the storage tank 12 needs to be cleaned, simply remove the shielding groove 3 from the storage tank 12, put the new shielding groove 3 into the storage tank 12, and then lock the clamping rod 31 on the side of the storage tank 12 to replace the adhesive in the storage tank 12. After the release film comes into contact with the glue roller 13 for coating, the release film will move towards the drying box 4 due to the traction of the winding package. The heating rod 41 can dry the adhesive on the surface of the release film, and the heat insulation plate 42 can dry the adhesive. The heat emitted by the heating rod 41 blocks the heat away from the side of the adhesive storage tank 12. When the heating rod 41 is drying the release film, the air pump 5 can also be activated, and then the air jet 51 sprays out airflow. The airflow can blow the adhesive on the surface of the release film, so that the adhesive on the surface of the release film dries faster. The inclined setting of the air jet 51 works with the heat of the heating rod 41, so that the airflow is inclined and blown continuously to dry the adhesive on the surface of the release film. The sealing gasket 6 can cover the gaps on the sides of the push plate 2 and the collection box 16, so that the adhesive will not flow out from the side due to the push of the push plate 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
