DETAILED DESCRIPTION

[0021] The following will be combined with the attached embodiment of the utility model Figure 1-5 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As shown in the figure, a roller mechanism for pre-coated film production that is easy to maintain includes a frame 1, on which a roller 2 is rotatably arranged, and on which a cleaning component located on one side of the roller 2 is arranged. The cleaning component includes a sliding frame 3 and a sandblasting head 4. The sliding frame 3 can be slidably arranged on one side of the roller 2 in a direction parallel to the axial direction of the roller 2, and the sliding frame 3 is transmission-connected to a first driving source, and the sandblasting head 4 is fixedly arranged on the sliding frame 3, and the nozzle of the sandblasting head 4 faces the roller 2.

[0023] Specifically, the cleaning assembly also includes a dust cover 5 arranged on the frame 1 on one side of the roller 2, and the dust cover 5 is composed of a top plate 51, a bottom plate 52, a left plate 53 and a right plate 54, so that the dust cover 5 has an aligned front end opening and a rear end opening, the front end opening faces the roller 2, and the sandblasting head 4 extends into the dust cover 5 through the rear end opening.

[0024] Specifically, the sliding frame 3 is slidably arranged and connected to the first driving source in transmission: a first linear slide rail 6 parallel to the axial direction of the roller 2 is arranged on the upper surface of the top plate 51, the upper end of the sliding frame 3 is fixedly connected to the sliding seat of the first linear slide rail 6 and the sliding frame 3 is located on the side of the rear end opening, the first driving source is a motor 7 arranged on the bottom plate 52, a synchronous belt 8 connected to the motor 7 in transmission is arranged on the lower surface of the bottom plate 52, and the lower end of the sliding frame 3 is fixedly connected to the synchronous belt 8.

[0025] Specifically, the front ends of the top plate 51, the bottom plate 52, the left plate 53 and the right plate 54 are respectively provided with a first sealing strip 91, a second sealing strip 92, a third sealing strip 93 and a fourth sealing strip 94 whose ends are abutted against the rotating roller 2, and the rear ends of the top plate 51 and the bottom plate 52 are respectively provided with a fifth sealing strip 95 and a sixth sealing strip 96 whose ends are abutted against each other, and the sandblasting head 4 passes between the fifth sealing strip 95 and the sixth sealing strip 96, and the first sealing strip 91, the second sealing strip 92, the third sealing strip 93, the fourth sealing strip 94, the fifth sealing strip 95 and the sixth sealing strip 96 are made of rubber material.

[0026] In the above embodiment, the sandblasting head 4 is connected to the sandblasting machine through a hose (the sandblasting machine is a common prior art and is not described here). When the roller 2 needs to be cleaned and maintained, the sandblasting machine works and sprays abrasives onto the surface of the roller 2 through the sandblasting head 4. At the same time, the motor 7 drives the synchronous belt 8 to drive the sliding frame 3 to slide on the first linear slide rail 6, thereby driving the sandblasting head 4 to move in a direction parallel to the axial direction of the roller 2. In conjunction with the self-rotation of the roller 2, the abrasive sprayed from the sandblasting head 4 is used to sandblast the surface of the roller 2 to achieve cleaning and maintenance of the roller 2. Through the above manner, when the roller 2 is cleaned and maintained, there is no need to disassemble and assemble the roller 2, thereby facilitating the cleaning and maintenance operations of the roller 2. In the process of the sandblasting head 4 moving and spraying abrasives onto the surface of the roller 2, the nozzle of the sandblasting head 4 is always kept inside the dust cover 5, and the dust during the sandblasting process is suppressed by the action of the dust cover 5. The dust is prevented from flying, and the first sealing strip 91, the second sealing strip 92, the third sealing strip 93 and the fourth sealing strip 94 are all against the roller 2, so that the sealing between the front end opening of the dust cover 5 and the roller 2 is strengthened, and the ends of the fifth sealing strip 95 and the sixth sealing strip 96 are against each other and the sandblasting head 4 passes through the two and then extends into the dust cover 5, so that the sealing between the rear end opening of the dust cover 5 and the sandblasting head 4 is strengthened, so that the sandblasting head 4 is in a relatively sealed working space when moving sandblasting, thereby further suppressing the flying of dust, effectively ensuring the cleanliness of the working environment and the personal health of the workers, and after the sandblasting head 4 completes the sandblasting operation on the roller 2, the dust attached to the surface of the roller 2 is cleaned up by the scraping action of the first sealing strip 91, the second sealing strip 92, the third sealing strip 93 and the fourth sealing strip 94 that are in contact with the roller 2, thereby ensuring the effect of cleaning and maintenance of the roller 2.

[0027] Preferably, a waste discharge pipe 10 connected to the inside of the dust cover 5 is fixedly connected on the lower surface of the base plate 52. The waste discharge pipe 10 is connected to the exhaust fan through a hose. When the sandblasting head 4 moves to blast, the exhaust fan works to remove the abrasive and residue in the dust cover 5, which facilitates the recovery of the abrasive while suppressing dust.

[0028] Furthermore, the dust cover 5 can be longitudinally slidably disposed on the frame 1 and is drivingly connected to the second driving source.

[0029] Specifically, the dust cover 5 is slidably arranged in a structure of transmission connection with the second driving source: a plurality of second linear guide rails 11 are respectively arranged on one side of the left plate 53 and the right plate 54 on the frame 1, and the left plate 53 and the right plate 54 are respectively fixedly connected to the sliding seats of the second linear guide rails 11 on the corresponding sides, and the second driving source is a cylinder 12 arranged on the frame 1, and the output shaft of the cylinder 12 is fixedly connected to the bottom plate 52 upward.

[0030] In the above preferred embodiment, the cylinder 12 can drive the dust cover 5 to slide longitudinally on the first linear slide rail 6 by pushing the bottom plate 52. When the roller 2 needs to be cleaned and maintained, the cylinder 12 drives the dust cover 5 to slide upward so that the first sealing strip 91, the second sealing strip 92, the third sealing strip 93 and the fourth sealing strip 94 are in conflict with the surface of the roller 2, and at the same time, the dust cover 5 and the sandblasting head 4 are moved to one side of the roller 2, so that the cleaning assembly can clean and maintain the roller 2. After the cleaning and maintenance of the roller 2 is completed, the cylinder 12 drives the dust cover 5 to slide downward so that the first sealing strip 91, the second sealing strip 92, the third sealing strip 93 and the fourth sealing strip 94 leave the position of conflicting with the surface of the roller 2, and at the same time, the dust cover 5 and the sandblasting head 4 are away from the roller 2 to prevent the dust cover 5 from interfering with the traction and transportation of the plastic film by the roller 2.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
