Description

Technical Field

[0001] The utility model relates to the field of coating machines, in particular to a coating roller which is easy to clean. Background Art

[0002] The coating machine is mainly used for the surface coating process production of film, paper, etc. This machine is to coat the rolled substrate with a layer of glue, paint or ink with specific functions, and then reel it up after drying. The coating roller is an important component for evenly transferring the coating slurry on the coating machine. Its surface needs to maintain a constant temperature at all times so that the slurry passing through it can be evenly coated on the surface of film, paper, etc. During the coating process, the coating may form dry knots or residues on the roller surface, which will affect the coating quality. Therefore, regular cleaning is required to remove these residues. For this reason, we have proposed a coating roller that is easy to clean. Utility Model Content

[0030] A through groove 14 is formed at the top of the gantry 6, and chutes 15 are formed on both sides of the through groove 14 on the top of the gantry 6. The L-shaped clamping block 12 drives the clamping plate 7 and the other group of L-shaped clamping blocks 12 to slide in the through groove 14 and the other group of chutes 15 respectively.

[0034] Working principle: When using this device, first, the relative rotation of two sets of clamping shafts 4 is used to convey the paper 5. The coating roller 3 rotates self - sufficiently to apply coating on the outer surface of the paper 5. When it is necessary to replace the coating and remove the coating dried on the outer wall of the coating roller 3, the main motor 9 and the auxiliary motor 19 are started simultaneously. The output shaft of the main motor 9 drives the turntable 10 to rotate self - sufficiently. One end of the rocker 11 makes a circular motion on the outer ring of the turntable 10 due to the self - rotation of the turntable 10. The other end of the rocker 11 drives one set of L - shaped clamping blocks 12 to slide in the chute 15 through the connecting rod 13. The L - shaped clamping blocks 12 drive the clamping plate 7 and the other set of L - shaped clamping blocks 12 to slide in the through - slot 14 and the other chute 15 respectively. The clamping block 8 slides left and right on the top of the coating roller 3 due to the sliding of the clamping plate 7. The transmission belt 20 drives the rotating rod 16 to rotate mechanically through the output shaft of the auxiliary motor 19. The rotating rod 16 drives the cleaning roller 17 to rotate synchronously. Multiple cleaning plates 18 scrape the residual coating on the outer wall of the coating roller 3 through the rotation of the cleaning roller 17.
