Description

Technical Field

[0001] The utility model relates to the technical field of light box cloths, in particular to a light box cloth cutting machine with anti-wrinkle function. Background Art

[0002] Light box cloth refers to a light box sign fabric composed of two layers of PVC and one layer of high-strength mesh cloth, also known as Polaroid cloth. It is divided into two types: internal lighting and external lighting. The main production methods are knife coating, calendaring, and lamination. It is characterized by high thickness and strong tensile strength. In order to adapt to light box structures of different specifications, existing light box cloth is trimmed by manual cutting;

[0003] Publication No. CN216464810U discloses a cutting device for processing light box cloth, which plays a buffering role when the connecting plate is lowered through the cooperation of the connecting tube, the tension spring and the sliding rod, thereby playing a buffering role for cutting, greatly reducing the occurrence of damage to the cutting knife and improving its service life. Through the cooperation of the compression spring and the pressure plate, the light box cloth is first pressed and then cut, which facilitates the cutting work and is convenient for use.

[0004] However, the above-mentioned cutting device for light box cloth still has the following problems during actual use: although the light box cloth is cut after being pressed by the compression spring and the pressure plate, the compression of the light box cloth by the compression spring and the pressure plate cannot flatten the original wrinkled parts of the light box cloth, which causes the pressure plate to press and raise the indentation on the wrinkled parts, and even causes the light box cloth to be damaged. At the same time, the overall pressed light box cloth will also be hindered by the pressure plate during the subsequent cutting process, thereby affecting the cutting of the light box cloth.

[0005] Therefore, we propose a wrinkle-proof light box cloth cutting machine to solve the above-mentioned problems. Utility Model Content
