Description

Technical Field

[0001] The utility model relates to the technical field related to the processing of coated paper, in particular to a coated paper slitting device. Background Art

[0002] Coated paper is a composite material obtained by coating plastic particles on the surface of paper through a casting machine. Its main characteristics are that this composite material can relatively prevent oil and water and can be heat-sealed. During the actual use of coated paper, according to requirements, it needs to be cut into different lengths, and the cutting process needs to be completed with the help of a cutting device.

[0003] After a large amount of retrieval, it is found that the prior art publication number is CN218255402U, which discloses a slitter for processing coated paper, including a supporting bottom plate. Two mounting side plates are fixedly installed on the top of the supporting bottom plate. A first rotating shaft is rotatably connected between the mounting side plates. A conveying roller is fixedly installed on the surface of the first rotating shaft. A second rotating shaft is rotatably connected between the mounting side plates. In the utility model, the first rotating shaft is driven to rotate by setting a first motor, and then the first rotating shaft drives the conveying roller to rotate. The conveying roller is used for conveying the coated paper. Under the action of a second motor, the second rotating shaft is driven to rotate, and then the second rotating shaft drives the slitting roller to rotate, so that the slitting knife slits the coated paper passing through the top of the slitting roller. The cut waste falls into the interior of the collection box. At the same time, the problem that the existing coated paper processing does not have the function of recycling these wastes, resulting in waste of coated paper raw materials and reduction of the production efficiency of enterprises, is solved.

[0004] In summary, when the existing coated paper cutting equipment cuts coated paper, it usually unwinds the coated paper under the cutting knife and then performs cutting treatment. However, during cutting, the coated paper is not pressed, so problems such as position deviation may occur before and after the slitting of the coated paper.

[0005] In view of the above defects, the designer actively conducts research and innovation in order to create a coated paper slitting device with more industrial utilization value. Summary of the Utility Model

The limit baffle is installed at the bottom of the material pressing base frame through a limit baffle mounting frame.

[0014] As a further improvement of the present utility model, the slitting assembly successively includes a slitting lifting cylinder, a slitting knife mounting frame, a slitting knife and a lower support seat from top to bottom. The driving end of the slitting lifting cylinder drives the lower slitting knife mounting frame to move in the vertical direction.
