Technical Field

[0001] This utility model relates to the field of paper processing technology, specifically to a guide-type decorative paper cutting device that prevents deviation. Background Technology

[0002] Decorative paper is an essential raw material in many building materials products, such as low-pressure boards and high-pressure boards used in furniture and cabinets, as well as fireproof boards and flooring. In the product structure, decorative paper is placed under the surface paper, mainly to provide decorative patterns and to cover and prevent the adhesive from seeping through.

[0003] In the process of cutting decorative paper, it is necessary to cut the decorative paper of uniform width to the required width for subsequent processing. However, when using existing cutting devices (such as the technical solution disclosed in patent application number CN202323021563.2), the decorative paper is usually conveyed and cut by the rotation of rollers. During the cutting process, the cutting blade is prone to deviation, causing the paper to slip to one side. This results in insufficient width on one side during cutting, affecting the cutting quality. Furthermore, when adjusting the cutting width, if there are multiple cutting blades, the existing cutting device cannot quickly adjust to make the spacing between adjacent cutting blades consistent. Utility Model Content

[0004] Therefore, in order to overcome any of the above-mentioned shortcomings, this utility model provides an anti-deviation guide decorative paper cutting device. This cutting device, through the setting of guide plates and guide rollers, can facilitate the guiding and traction of paper, avoiding paper deviation during the cutting process. At the same time, the guide plates are set in a movable installation form, which can facilitate the adjustment of the distance between the two guide plates, thereby facilitating the guiding and conveying of paper of different widths. Furthermore, by reasonably setting the cutting mechanism and the adjustment mechanism, multiple cutting blades can be quickly installed, and the distance between the cutting blades can be made consistent, thereby cutting the paper into paper of the same width.

[0005] This utility model is implemented as follows: a guide-type decorative paper cutting device for preventing deviation includes a bracket, with a feeding roller on the outer side of one end and a receiving roller on the outer side of the other end.
