Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of home textile manufacturing, and particularly to a home textile product with controllable patch width and self-positioning live fold pull cylinder. BACKGROUND

[0002] The sewing technology of self-live fold on the patch is a common process in the home textile products such as quilt covers, pillow covers and cushion covers in recent years. Specifically, one live fold, two live folds, three live folds or more live folds are folded on the patch, and then are sewn by pressing the line to form a multi-level effect, which is favored in the field of home textiles.

[0003] Currently, there are two conventional methods for the production of the multi-edge self-live fold of the home textile product patch. The first method is to directly measure the size with a ruler and control the live fold distance from the edge, the live fold width and the interval by ironing. The second method is to control the live fold distance from the edge by the airplane baffle and control the live fold width and the interval by the needle position of the sewing machine. The above methods have the following disadvantages:

[0004] 1. The size of the fold produced by the first method is inconsistent, the distance from the edge of the fold is inconsistent, the operation method is complicated, and the auxiliary time is too long.

[0005] 2. In the process of producing the fold on the patch by the second method, the flash will be tightly pressed against or separated from the baffle, which still causes the size of the fold to be inconsistent, and the line is not straight and smooth.

[0006] Moreover, the folds produced by the two methods are vertical, and after the production is completed, the produced fold needs to be ironed in the reverse direction. When ironing, the reverse side of the fold is easy to be sandwiched with the cloth and not easy to be completely ironed open, which affects the appearance quality of the product, cannot be continuously operated, has low work efficiency, and is not suitable for batch production. SUMMARY

[0007] To overcome the shortcomings of the prior art, the present utility model aims to provide a home textile product with controllable patch width and self-positioning live fold pull cylinder, which is suitable for the production of home textile products with live fold pressing line on patches of different widths and intervals, and solves the problems of poor product quality and low work efficiency.

[0008] To achieve the above-mentioned purpose of the invention, the home textile product with controllable patch width and self-positioning live fold pull cylinder comprises a live fold distance inner edge control groove, a fold position control groove, a live fold distance outer edge control groove and a fold large control plate. The right end of the live fold distance inner edge control groove is connected with the fold position control groove, the live fold distance outer edge control groove is communicated with the fold position control groove, and the fold large control plate deeply enters the inside of the fold position control groove to the left. The bottom surface of the pull cylinder is adhered to the surface of the sewing machine table by double-sided strong adhesive, and the needle of the sewing machine is located at the right end of the fold position control groove to the left by 0.8 cm.

[0009] Further, the live crease distance inner edge control groove comprises a live crease distance inner edge control groove upper plane, a live crease distance inner edge control groove transition arc and a live crease distance inner edge control groove lower plane; the length of the live crease distance inner edge control groove upper plane is smaller than the length of the live crease distance inner edge control groove lower plane, the live crease distance inner edge control groove upper plane is parallel to the live crease distance inner edge control groove lower plane, and the left end of the live crease distance inner edge control groove upper plane is connected to the left end of the live crease distance inner edge control groove lower plane through the live crease distance inner edge control groove transition arc.

[0010] Further, the live crease distance inner edge control groove comprises a live crease distance inner edge control groove upper plane, a live crease distance inner edge control groove transition arc and a live crease distance inner edge control groove lower plane; the length of the live crease distance inner edge control groove upper plane is smaller than the length of the live crease distance inner edge control groove lower plane, the live crease distance inner edge control groove upper plane is parallel to the live crease distance inner edge control groove lower plane, and the left end of the live crease distance inner edge control groove upper plane is connected to the left end of the live crease distance inner edge control groove lower plane through the live crease distance inner edge control groove transition arc.

[0011] Further, the live crease distance inner edge control groove comprises a live crease distance inner edge control groove upper plane, a live crease distance inner edge control groove transition arc and a live crease distance inner edge control groove lower plane; the length of the live crease distance inner edge control groove upper plane is smaller than the length of the live crease distance inner edge control groove lower plane, the live crease distance inner edge control groove upper plane is parallel to the live crease distance inner edge control groove lower plane, and the left end of the live crease distance inner edge control groove upper plane is connected to the left end of the live crease distance inner edge control groove lower plane through the live crease distance inner edge control groove transition arc.

[0012] Further, the live crease distance inner edge control groove, the live crease distance outer edge control groove, the live crease distance outer edge control groove and the live crease distance outer edge control groove are made of stainless steel and have no burrs.

[0013] In use, the bottom surface of the pull cylinder is adhered to the sewing machine table by double-sided strong adhesive, so that the distance between the pull cylinder and the needle meets the process requirements of the folding amount and the distance from the edge of the home textile product, the patch pieces are sequentially inserted into the live crease distance outer edge control groove, the live crease distance inner edge control groove and the live crease distance outer edge control groove, and the sewing machine motor is started, so that the patch pieces are sewn, and the live crease distance outer edge control groove and the live crease distance outer edge control groove jointly control the folding amount of the home textile product.

[0014] Compared with the prior art, the folding position, folding amount, size and width of the home textile product can meet the process requirements, the quality is stable, the operation is simple, the adjustment is convenient, and the product quality and production efficiency of the folded patch pieces are greatly improved.
