Description

TECHNICAL FIELD

[0001] The utility model relates to the production technology field of pearlescent paper more specifically, it relates to a kind of coating roll for pearlescent paper production. BACKGROUND

[0002] The composition of pearlescent paper is the same as ordinary white board paper, i.e., it is composed of three parts of bottom layer fiber, filler and surface coating layer. Unlike ordinary white board paper, the surface coating layer has particles that form a pearlescent effect. The coating roll can achieve simple coating operation and is suitable for the formulation of coating film for various substrates. It can coat paint on many kinds of substrates, including paper, paperboard, plastic film, foil, metal plate, glass plate and wood board, etc. The coating roll is widely used in modern pearlescent paper production process.

[0003] For example, the anti-sticking coating roll for pearlescent paper production disclosed in the authorization announcement No. CN211079759U adopts a double-shaft reverse drive transmission structure, thereby realizing the reverse rotation of the first coating roll when the second coating roll rotates for coating. The coating glue layer is cut off and separated from the second coating roll. At the same time, due to the adoption of the elliptical structure of the first coating roll and the through slot formed on the first coating roll, the adhesive area of the first coating roll and the coating glue layer is reduced, and the adhesion is reduced.

[0004] In the above, although the adhesion can be reduced, but in the actual use process, a small amount of coating layer will inevitably adhere to the surface of the coating roll. If the adhesion area of the coating layer is not cleaned in time, the adhesion area will gradually increase, which will affect the coating effect. The current cleaning method is to manually remove the coating roll for cleaning, which is relatively troublesome and low in efficiency. UTILITY MODEL CONTENT

[0021] 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 protection scope of the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Working principle: When in use, connect the drive shaft 3 to the external power output mechanism. At this time, the coating roller does not need to be cleaned. The rotating disk rotates, and the rotating rod 12 is located at the top of the rotating disk. Since the rotating rod 12 is engaged with the slot on the lifting plate 8, the rotating rod 12 will drive the lifting plate 8 to rise. The lifting plate 8 is connected to the brush 6. At this time, the brush 6 is also placed at the highest point of the mounting frame 5, which will not affect the operation of the coating roller.

[0024] After the coating roller is used up, the drive motor 7 is controlled to rotate. The output end of the drive motor 7 drives the rotating disk to rotate. Since the rotating rod 12 is engaged with the slot, the height of the lifting plate 8 will also change during the rotation position movement until the brush 6 contacts the surface of the coating roller. Then the drive motor 7 stops working and connects the transmission roller to the external power output mechanism again to make the coating roller rotate. Since the outer peripheral wall of the coating roller contacts the brush 6, the scraper 15 and brush bristles 16 will clean the coating residue on the outer peripheral wall of the coating roller during the rotation. When there is too much residue on the brush 6, the brush 6 can be removed and replaced.

[0025] like Figs. 1 to 3 As shown,

[0026] It includes a coating roller body 1, a frame 2, and a drive shaft 3 that is rotatably connected to the frame 2 on both sides. The drive shaft 3 is fixedly connected to the coating roller body 1. Cleaning devices 4 are provided on both sides of the coating roller body 1 to clean the coating residue on the outer peripheral wall of the coating roller.

[0027] The cleaning mechanism includes a mounting frame 5, a brush 6, a drive motor 7, and a lifting plate 8. There are two mounting frames 5, which are respectively placed on both sides of the coating roller and fixed to the end face of the frame 2 to ensure the stability of the mounting frames 5.

[0028] Both mounting brackets 5 have slide grooves 139 on their side walls. Both sides of the lifting plate 8 are placed in the slide grooves 139 and are slidably connected to the slide grooves 139. The height of the lifting plate 8 is adjusted by moving the lifting plate 8 in the slide grooves 139.

[0029] The frame 2 is equipped with a support frame 10 for connecting the drive motor 7. The drive motor 7 is fixedly connected to the side wall of the support frame 10, and the support frame 10 installs the drive motor 7 at a suitable height.

[0030] The output end of the drive motor 7 passes through the support frame 10 and is connected to an eccentric disk 11. The eccentric disk 11 includes a disc and a connecting rod 17 placed at the eccentric position of the disc. The rotating rod 12 is connected to the connecting rod 17, and the position of the connecting rod 17 is adjusted by rotating the eccentric disk 11.

[0031] A rotating rod 12 is connected to the eccentric disc 11, and a horizontal groove is provided on the lifting plate 8 for the rotating rod 12 to extend into. The height of the lifting plate 8 can be adjusted by changing the position of the rotating rod 12.

[0032] The brush 6 is placed between two lifting plates 8. The brush 6 includes a connecting frame 14, a scraper 15 and bristles 16. Both ends of the connecting frame 14 are detachably connected to the lifting plates 8. The scraper 15 and the brush 6 are both fixed to the lower end face of the connecting frame 14. The scraper 15 can scrape off the residual coating, and the bristles 16 can clean the fine dust.

[0033] A through groove is provided on the lower end face of the connecting frame 14, and one end of the brush bristles 16 and the scraper 15 are placed in the through groove and fixed by screws.

[0034] The lowest point of the lifting plate 8 is positioned above the drive shaft 3, which can prevent the lifting plate 8 from colliding with the drive shaft 3 when adjusting its height, thus avoiding any impact on the operation of the coating roller.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
