Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic substrate coating equipment, and in particular relates to a coating head residual glue leakage recovery device and a coating machine. Background Art

[0002] A coating machine is a device used to apply a layer of glue, paint or ink with specific functions on the surface of a substrate. Coating machines are mainly used for surface coating of films, paper, cloth, textiles, electronic products, etc., which can change the performance, appearance or function of the substrate. The working principle of the coating machine is to evenly apply the coating on the surface of the substrate. The coating machine is mainly composed of a coating head, a reel, a drying device, a control system, etc. The coating head is the core component of the coating machine, which is used to spray or apply the coating evenly on the surface of the substrate.

[0003] In the prior art, a coating machine is generally used to apply coating to the flexible backplane substrate of a photovoltaic module. During the coating production process, residual glue will be left on the traction roller after the coating action is completed. The residual glue accumulates and drips, affecting product production. It is necessary to manually remove the residual glue on the roller, which consumes manpower and material resources, increases costs, and affects production safety.

[0004] Therefore, it is necessary to provide a leaking glue recovery device which saves manpower and material resources and does not affect normal operation. Utility Model Content

[0005] In view of this, the utility model aims to solve at least one of the technical problems in the related art to a certain extent. To this end, one purpose of the utility model is to provide a coating head residual glue leakage recovery device and a coating machine including the device, which has a reasonable structural design, a tight connection, convenient assembly and disassembly, and can automatically clean residual glue and overflow glue, saving manpower and material resources.

[0006] To achieve the above-mentioned purpose, in one aspect of the utility model, the utility model provides a coating head residual glue leakage recovery device, which is located between two coating head machine bodies arranged at intervals, and includes: a heating roller rotatably connected to the inner sides of the two coating head machine bodies, and a glue receiving box located below the heating roller, the glue receiving box is fixedly connected to the inner side of one of the coating head machine bodies through a fixed connecting piece, and a scraper is connected to the inlet of the glue receiving box, and the scraper abuts against the roller surface of the heating roller.

[0007] Preferably, the inner side of the coating head machine body is detachably connected with a first fixed connector, and the glue box is detachably connected to the first fixed connector via a second fixed connector. It is further preferred to use bolts for fastening and disassembly of the glue box, which is convenient for replacement.

[0008] Preferably, the scraper is detachably connected to the adhesive box. As a consumable part, the scraper is preferably fixed to the adhesive box by bolts to facilitate replacement of the worn scraper.

[0009] Preferably, the scraper is made of a material with lower strength than the heating roller. The scraper plays the role of guiding and scraping glue and is in contact with the heating roller. Therefore, setting a material with lower strength can ensure the service life of the heating roller.

[0010] Preferably, the scraper is elastically abutted against the roller surface of the heating roller. For example, the scraper can be fixedly connected to the glue box through an elastic connecting piece to ensure that the scraper is always abutted against the heating roller.

[0011] Preferably, the scraper and the heating roller are tilted and matched at an angle of 30° to achieve a better effect of scraping off residual glue.

[0012] Preferably, the width of the scraper covers the glue leaking surface of the heating roller. The size of the glue receiving box and the width of the scraper are adaptively adjusted according to the size of the glue leaking area.

[0013] In another aspect of the utility model, the utility model also provides a coating machine, including a glue groove, a glue coating roller, and a traction roller located on the inner side of the coating head machine body, and also includes at least one coating head residual glue leakage recovery device located at the rear end of the glue coating roller, and the coating head residual glue leakage recovery device is any of the coating head residual glue leakage recovery devices described above.

[0014] The utility model discloses the following beneficial effects:

[0015] The utility model coating head residual glue leakage recovery device fixes the glue box equipped with a scraper for scraping glue and guiding to the inner side of the coating head machine body through a special fixed connector, and the connection is stable, easy to disassemble and assemble, and does not damage the original mechanical structure; the newly added hot roller can be fixed to the inner side of the coating head by a special fixed connector, and is located at the rear end of the coating roller. The scraper fastened by bolts on the glue box can smoothly scrape off the residual glue leakage adhered to the heated roller, and the scraped glue slides down to the glue box. The glue box can be quickly disassembled and installed, which is convenient for residual glue recovery. The strength of the special scraper material is lower than that of the newly added heated roller, which does not affect the service life of the newly added heated roller, the mechanical structure of the equipment, and the product production. Therefore, the utility model coating head residual glue leakage recovery device has the beneficial effects of reasonable structural design, tight connection, convenient disassembly and assembly, and convenient residual glue recovery. The coating machine equipped with the utility model coating head residual glue leakage recovery device can effectively protect the coating head, automatically complete the cleaning of residual glue and overflow, and save manpower and material resources.
