[0005] Further, the axes of the scraping mechanism, the wiping mechanism and the waste collecting box are parallel to the axis of the coating roll.

[0006] Further, the scraping mechanism, the wiping mechanism and the waste collecting box are located on the side of the coating roll away from the foil.

[0007] Further, the scraping mechanism comprises a scraper mounting seat and a scraper arranged on the scraper mounting seat, the scraper mounting seat is mounted on the rack of the coating machine, and the scraper is in abutment with the coating roll.

[0008] Further, the scraper is made of plastic material.

[0009] Further, the wiping mechanism comprises a supporting plate and a cleaning cloth, the supporting plate is mounted on the rack of the coating machine, the cleaning cloth is mounted on one side of the supporting plate close to the coating roll, and the cleaning cloth is in abutment with the coating roll.

[0010] The utility model has the following beneficial effects:

[0011] The utility model discloses a coating roll automatic cleaning device can be realized in the non-stop state, to the coating roll real -time online cleaning, in time clean off the particle and foreign matter on the coating roll, eliminate foil scratch, cut off the risk, make coating procedure can continuous production, improved the production efficiency of coating machine and the qualified rate of coating product, effectively avoided the security risk that staff wipes.

[0017] To achieve the above purpose and effect, the technical means and structure adopted by the utility model are described in detail in combination with the preferred embodiments of the utility model, and the characteristics and functions are described.

[0018] As Figures 1-4 As shown in the utility model, a kind of coating machine coating roll automatic cleaning device is provided, including scraping mechanism 5, wiping mechanism 4 and waste collection box 6;The scraping mechanism 5, wiping mechanism 4 and waste collection box 6 are fixed on the rack of coating machine, as preferred embodiment, the axis of the scraping mechanism 5, wiping mechanism 4 and waste collection box 6 are all parallel with the axis of coating roll;The scraping mechanism 5, wiping mechanism 4 and waste collection box 6 are all located on the side of coating roll 2 away from foil 3;The scraping mechanism 5 and wiping mechanism 4 are all in contact with coating roll 2, and the waste collection box 6 is arranged below scraping mechanism 5.

[0019] The scraping mechanism 5 includes scraping knife mounting seat 51 and scraping knife 52 arranged on scraping knife mounting seat 51, and the scraping knife mounting seat 51 is mounted on the rack of coating machine, and the scraping knife 52 is in contact with coating roll 2.The scraping knife 52 adopts plastic material, which can effectively avoid the generation of metal dust.

[0020] The wiping mechanism 4 comprises a support plate 41 and a cleaning cloth 42, the support plate 41 is installed on the frame of the coating machine, the cleaning cloth 42 is installed on the support plate 42 close to one side of the coating roller 2, and the cleaning cloth 42 is in abutment with the coating roller 2.

[0021] The working principle is as follows:

[0022] The coating roller 2 rotates to drive the foil 3 to move at a constant speed, the coating die head 1 sprays the slurry in it onto the foil, and the pole piece is formed through baking, which is used for production in the subsequent process. In this process, the dust particles and foreign matters on the surface of the coating roller 2 rotate synchronously with the coating roller, when the coating roller 2 rotates to the position of the scraper 52, the scraper 52 scrapes off the dust particles and foreign matters on the surface of the coating roller 2, the scraped dust particles and foreign matters are effectively collected by the waste collecting box 6, so that secondary pollution of the coating roller 2 is avoided. The wiping mechanism 4 wipes and cleans the particles and foreign matters that are not completely cleaned, so that effective and complete cleaning is achieved, the surface of the coating roller 2 is ensured to be clean and clean, and the coating process is smoothly produced.
