Technical Field

[0001] The utility model relates to the technical field of advertising cloth cutting, in particular to a limiting device for advertising cloth cutting. Background Art

[0002] Advertising cloth is one of the most widely used and most in-demand cloth consumables. It is mainly used for indoor and outdoor banners, flags, curtains, scenery pictures, etc., because it is made of synthetic fiber as the base material. Among them, inkjet cloth is also a kind of advertising cloth. In the production process of advertising cloth, an advertising cloth cutting machine is needed to cut it into the required size to meet the needs of users. In the process of cutting advertising cloth, the most important point is to limit and fix the cloth. Otherwise, the cut advertising cloth will not meet the requirements due to the deviation of the cloth during cutting. Therefore, we have launched a limiting device for cutting advertising cloth.

[0003] The existing technology has the following problems: 1. The existing advertising cloth is usually fixed by manual assistance or by using heavy objects to press it. The above fixing methods are not only unstable and unsafe, but also increase the work intensity to a certain extent; 2. At the same time, during the cutting process of the advertising cloth, the width of each advertising cloth is not consistent, and its limiting device is inconvenient to adjust according to advertising cloths of different widths, and its adaptability is low. Summary of the invention

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, the auxiliary limiting wheel is driven to rotate around the rotating shaft by toggling the limiting rod, so that the auxiliary limiting wheel is separated from the main limiting wheel. At this time, the edge of the advertising cloth can be put between the two limiting wheels, and then the limiting rod is loosened. Under the action of the torsion spring, the auxiliary limiting wheel will be reset, so that the advertising cloth is clamped between the two limiting wheels. After the four corners of the advertising cloth are all fixed, the second motor is started to drive the main limiting wheel to rotate, and the corners of the advertising cloth are pulled outward, so as to eliminate the wrinkles on the surface of the advertising cloth. There is no need to manually fix the advertising cloth, and the fixing effect is better and more stable.

[0014] In the utility model, the two sliding blocks are driven to move in opposite directions by rotating the bidirectional screw in the adjustment component, thereby driving the limit component to move, so as to adjust the distance between the two groups of gantries according to the different lengths of advertising cloths. Then the locking bolt is screwed upward to disengage the bottom end of the locking bolt from the top surface of the gantry, and the sliding frame can be moved, thereby driving the limit component at the bottom to move synchronously, so as to achieve the purpose of adjusting the limit width.
