Description

Technical Field

[0001] The utility model relates to the technical field of PP cloth processing, in particular to automatic cutting equipment for PP cloth spacers. Background Art

[0002] PP cloth is a common man-made chemical fiber. Due to its good elasticity, strong bulk, beautiful shape, fear of extrusion, easy to wash and quick drying, it is often used in bedding factories, toy factories, spray-bonded cotton factories, non-woven fabric manufacturers and other manufacturers. When producing PP cloth spacers, automatic cutting devices are often used to cut the rolled spacer material into suitable sizes for easy use in subsequent processes. The automatic cutting device improves the production efficiency of PP cloth spacers.

[0003] Existing technology such as the utility model with publication number CN218284194U discloses a short-sleeved cloth cutting device. The patent adopts a frame, a cutting table is fixed on the top of the frame, and a cutting and pressing mechanism is provided on the top of the frame; the cutting and pressing mechanism includes two first guide rails, both of which are fixed on the top of the frame, and the outside of the two first guide rails are sleeved with guide rail sliders, and one side of the two guide rail sliders is fixedly connected to the bottom plate. A short-sleeved cloth cutting device has the following beneficial effects: when the cloth pressing rod in the cutting and pressing mechanism contacts the cloth, the cloth pressing rod is opened outward, so that the connecting plate belt The movable fixed block moves, and the slider is pulled along the slide groove by the steel wire rope, causing the spring to contract. In the process of the cloth pressing rod opening along the cloth surface, the cloth pressing rod exerts a certain pressure on the cloth, thereby pulling the cloth to both sides, making the cloth fully unfolded, eliminating wrinkles on the cloth surface, and ensuring the flatness of the cloth during subsequent cutting. This solves the problem that existing clothing cloth is usually cut after being laid flat on a cutting table in multiple layers. The cloth has a certain elasticity, and wrinkles are easily formed on the cloth surface after being laid flat, resulting in dimensional errors in the cut product due to wrinkles, affecting the flatness and cutting quality of the cloth.

[0004] The inventor discovered in his daily work that in the process of using automatic cutting equipment to process PP cloth spacers, there are existing cloth cutting devices such as the above-mentioned ones, in which extrusion structures are set on both sides of the cutting part to clamp the cloth during the cutting process. The contact structure in the extrusion structure is a columnar structure, and the columnar structure is set in a circular shape, so that when the columnar structure squeezes the cloth, the contact area between the columnar structure and the cloth is small, and the pressure applied makes the cloth under insufficient pressure. In addition, the extrusion structure uses the elastic force of the spring to limit the pressing part. When the force applied to the pressing part is greater than the force applied by the spring, the extrusion structure will find it difficult to press the cloth stably, resulting in the problem that the cloth will still have wrinkles during the processing process. Utility Model Content
