Description

Technical Field

[0001] The utility model belongs to the technical field of door curtain production equipment, and specifically relates to movable needle door curtain quilting production equipment. Background Art

[0002] Door curtains refer to curtains hung at the doors of homes, shopping malls, supermarkets, etc. There are cotton door curtains for insulation, mesh door curtains for keeping out mosquitoes, crystal plate door curtains with good permeability, etc. There are also slightly higher-end ones, such as magnetic cotton door curtains, magnetic mesh door curtains, and magnetic crystal plate door curtains. Traditional cotton door curtains are made by quilting with ordinary fixed-stitch quilting equipment, and magnetic crystal plate door curtains are produced by mechanical welding or adhesive bonding. However, to make cotton door curtains with magnetic effects, it is necessary to sew magnetic strips on the edges of door curtains of various sizes. Ordinary fixed-line-spacing quilting machines have the limitation of fixed-size needles, so the needles on both sides cannot be exactly located at the edge of the door curtain, and the cloth strips and magnetic strips that need to be hemmed cannot be wrapped around the edge of the door curtain. Manufacturers can only use relatively bulky single-needle thick-material sewing machines to manually drag and sew multiple The production of such door curtains is done by reciprocating sewing. The welding and bonding of crystal plate magnetic door curtains will not only pollute the environment, but also make the crystal plate hard after welding and bonding, and it is easy to crack and damage. In addition, many popular types such as leather and knife-scraped cloth cannot be welded. Sewing is the best solution, but the diversity of size customization makes ordinary fixed-size quilting machines far behind and completely unable to match production. It can only be completed by the most primitive single-head thick material sewing machine through manual dragging and reciprocating sewing, causing great labor waste and distress for door curtain processing manufacturers. Therefore, a movable needle quilting machine that can adjust the required size at will and complete the hemming quilting with multiple lines at one time has become an urgent need for the majority of door curtain manufacturers. Therefore, according to customer needs, our company has specially developed this new type of movable needle door curtain manufacturing quilting equipment to solve the pain points of door curtain manufacturers with such use requirements.

[0003] In view of this, this application is hereby filed. Utility Model Content
