Description

Technical Field

[0001] This utility model belongs to the field of coating machines, specifically, it relates to a coating machine that facilitates uniform coating. Background Technology

[0002] Coating machines are mainly used for surface coating processes of films, paper, etc. This machine coats a roll of substrate with a layer of adhesive, paint or ink with specific functions.

[0003] Patent application CN220425729U discloses a coating machine for uniform coating. Paragraph 0028 of the specification describes the following steps: When the coating machine is to operate, the film is first inserted through the feed inlet, then passed through the base surface, with one end of the film adhering to the surface of roller B. A knob is then turned counterclockwise, causing a threaded rod to rotate, which in turn causes the slider to move the scraper downwards. This ensures the gap between the scraper and the base surface matches the thickness of the fabric. The height of the scraper can be adjusted by rotating the knob, allowing the coating machine to evenly coat films of different thicknesses. As the film passes through the base surface, an adhesive applicator at the bottom of the mounting frame sprays coating onto the film surface. The scraper then ensures even coating, preventing waste or excessive consumption. A motor drives a rotating rod, which in turn rotates roller B, causing the roller to move the film. After the coating machine finishes operating, the scraper can be disassembled by turning a bolt counterclockwise for cleaning and maintenance.

[0004] In actual use, when the coating on the film surface is scraped with a scraper to make it evenly distributed, the scraper is prone to tilting because there is no guiding structure on one side. This will cause uneven coating on the film surface and disorder during film winding.

[0005] To address these shortcomings, a coating machine designed for uniform coating is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a coating machine that facilitates uniform coating, thus solving the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A coating machine that facilitates uniform coating includes a base and a coating assembly;

[0009] The coating assembly includes two support plates fixed on the base, a connecting plate between the two support plates, an adhesive applicator slidingly fitted to the bottom of the connecting plate, a sliding plate slidingly fitted inside the support plate, a guide roller rotating between the two sliding plates, a scraper engaging between the two sliding plates, and a positioning plate engaging inside the support plate, with one end of the positioning plate located inside the sliding plate.

[0010] Optionally, the glue applicator is connected to and communicates with two connecting pipes, and two first through holes are opened on the connecting plate. The connecting pipes are located in the first through holes, and an electric push rod is provided on the connecting plate. The glue applicator is fixedly connected to the output end of the electric push rod.

[0011] Optionally, the support plate has a T-shaped groove and a guide groove, the guide groove is connected to the T-shaped groove, the sliding plate is located in the T-shaped groove, the positioning plate is located in the T-shaped groove and the guide groove, the support plate has a threaded hole, the threaded hole is connected to the guide groove, and a bolt is threaded in the threaded hole, the bolt is engaged with the positioning plate.

[0012] Optionally, the sliding plate has a positioning groove, the positioning plate has a positioning block, one end of the positioning block is located in the positioning groove, the guide roller has two rotating rods, the scraper has two locking blocks, the sliding plate has a second through hole and a locking groove, the locking block is located in the locking groove, and one end of the rotating rod is rotatably engaged in the second through hole.

[0013] Optionally, the base has a placement groove, in which a first roller is rotatably fitted. The base has two support blocks, each with a third through hole. A second roller is rotatably fitted between the two support blocks. The second roller has two rotating shafts, one end of which is rotatably fitted into the third through hole.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] By setting a guide roller and scraper cooperation structure between two sliding plates, the guide roller is rotatably connected to the sliding plate through a rotating rod. It can rotate with the movement of the substrate and provide guidance. The scraper is fixed between the two sliding plates by being inserted into a slot by a locking block. With the auxiliary guidance of the guide roller, the scraper is kept vertical during scraping, reducing the problem of substrate tilting.

[0016] The positioning plate is embedded in the positioning groove of the sliding plate by the positioning block, and the bolt passes through the threaded hole of the support plate to abut against the positioning plate, so as to fix and fine adjust the position of the sliding plate. This structure not only prevents the sliding plate from shifting due to vibration during the scraping process, but also allows the height to be adjusted by loosening the bolt.

[0017] The sliding plate can slide up and down in the T-groove of the support plate. By adjusting the height of the sliding plate, it can be adapted to substrates of different thicknesses. For example, when the film thickness changes, the guide roller and scraper maintain a reasonable distance from the substrate surface.

[0018] The scraper is inserted into the slots of the sliding plate by the locking blocks at both ends, forming a horizontal locking connection, so that the scraper is always perpendicular to the substrate surface when scraping, reducing tilting or swaying caused by unilateral force.

[0038] Working principle:

[0039] When it is necessary to coat a substrate such as a film, the substrate is conveyed by the first roller 3 and the second roller 6 on the base 1. In the coating assembly, the glue applicator 13 can slide up and down along the connecting plate 11 via the electric push rod 12 to adjust to a suitable coating height. The glue is sprayed from the glue applicator 13 onto the surface of the substrate through the connecting pipe 15.

[0040] The sliding plate 16 can slide up and down in the T-shaped groove 9 of the support plate 8, driving the guide roller 17 and scraper 18 to move synchronously to adapt to substrates of different thicknesses. The positioning plate 24 is embedded in the positioning groove 23 of the sliding plate 16 through the positioning block 25, and the bolt 27 passes through the threaded hole 26 to abut against the positioning plate 24 to fix the position of the sliding plate 16.

The scraper 18 is fixed between the two sliding plates 16 by the locking block 20 being inserted into the locking groove 22. With the auxiliary guidance of the guide roller 17, it is kept vertical during scraping and tilting is reduced, so as to scrape the adhesive on the surface of the substrate evenly.

[0041] Beneficial effects:

[0042] The sliding plate 16 can slide up and down in the T-groove 9 of the support plate 8. By adjusting the height of the sliding plate 16, it can be adapted to substrates of different thicknesses. For example, when the film thickness changes, the guide roller 17 and scraper 18 can maintain a reasonable distance from the substrate surface.

[0043] The positioning plate 24 is embedded in the positioning groove 23 of the sliding plate 16 through the positioning block 25, and the bolt 27 passes through the threaded hole 26 of the support plate 8 to abut against the positioning plate 24, thereby fixing and fine-tuning the position of the sliding plate 16. This structure not only prevents the sliding plate 16 from shifting due to vibration during the scraping process, but also allows the height to be adjusted by loosening the bolt 27.

[0044] By setting a cooperative structure between the guide roller 17 and the scraper 18 between the two sliding plates 16, the guide roller 17 is rotatably connected to the sliding plate 16 through the rotating rod 19, and can rotate with the movement of the substrate and provide a guiding function. The scraper 18 is fixed between the two sliding plates 16 by being inserted into the slot 22 by the locking block 20. With the auxiliary guidance of the guide roller 17, the scraper is always kept vertical during the scraping process, reducing the problem of substrate tilting.
