Description

Technical Field

[0001] This invention relates to the field of home textile manufacturing technology, specifically to a pull tube for home textile products with controllable patch width and two equidistant folds. Background Technology

[0002] The technique of creating pleats on patchwork panels is a common process in home textile products such as duvet covers, pillowcases, and cushions in recent years. Specifically, it involves creating one, two, three, or even multiple pleats on the patchwork panels and then sewing them together with exposed stitching to form a staggered, multi-layered effect, which is highly favored in the home textile industry.

[0003] Currently, there are two common methods for creating a second fold after an initial pleat on a home textile patchwork: Method one involves directly measuring the dimensions with a ruler and controlling the pleat's distance from the edge, width, and spacing using ironing. Method two involves controlling the pleat's distance from the edge using a sewing machine's guide rail, and controlling the pleat's width and spacing using the sewing machine's needle position. Both methods have the following drawbacks: 1. The fold width of the puzzle pieces made using Method 1 is inconsistent, as is the distance from the edge of the fold. The operation is cumbersome and takes too long.

[0004] 2. When using method two to make folds on the pieces, the burrs may be pressed against or leave the baffle, resulting in inconsistent fold sizes and uneven creasing.

[0005] Moreover, the folds pressed out by both methods are vertical. After production, the folds need to be ironed in reverse. When ironing, the reverse side of the fold is prone to trapping the fabric and is not easy to iron out completely, which affects the appearance quality of the product. It cannot be operated continuously, has low work efficiency, and is not suitable for mass production. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, the present invention aims to provide a pull tube for home textile products with controllable patch width and two equidistant folds, so as to be suitable for the production of products with a second fold and exposed lines pressed on patches of different widths and spacing requirements, thereby solving the problems of poor product quality and low work efficiency.

[0007] To achieve the above-mentioned objectives, the pull tube for home textile products of the present invention, which allows for controllable patch width and equidistant folds, includes a first fold position slot, a second fold position control slot, a fold distance outer edge control slot, and a fold enlargement control plate. The bottom surface of the pull tube is adhered to the sewing machine table with double-sided strong adhesive, and the sewing machine needle is located 0.8 cm to the left of the right end of the second fold position control slot. The first fold position slot is connected to the fold enlargement control plate in sequence via the second fold position control slot and the fold distance outer edge control slot. The fold distance outer edge control slot communicates with the second fold position control slot, and the fold enlargement control plate extends to the left into the interior of the second fold position control slot.

[0008] Furthermore, the first folding slot includes an upper surface, a lower surface, a first transition arc, and a second transition arc. The upper surface and lower surface are parallel, and their right ends are connected via the second transition arc. The left end of the lower surface is tangentially connected to the bottom end of the first transition arc. A gap larger than the thickness of the home textile fabric is provided between the top end of the first transition arc and the lower side of the upper surface. The thickness and width of the first folding slot match the thickness of the first fold of the home textile product.

[0009] Furthermore, the second fold control groove includes an upper surface, a lower surface, and a transition arc. The upper surface and lower surface of the second fold control groove are parallel. The left end of the upper surface and the left end of the lower surface are connected by the transition arc. The right end of the upper surface is connected to the transition plane by the first transition arc. The transition plane extends to the left and connects to the leftward extension of the upper surface of the first movable fold slot by the second transition arc. The transition plane is parallel to the upper surface of the first movable fold slot, the upper surface of the second fold control groove, and the lower surface of the second fold control groove. A gap larger than the thickness of the home textile fabric is provided between the lower surface of the first movable fold slot and the transition plane. The lower surface of the second fold control groove extends to the right and is tangent to the lower end of the transition arc of the outer edge control groove of the movable fold.

[0010] Furthermore, the folding control plate includes a folding control plate surface and a folding control plate transition arc; a gap larger than the thickness of the home textile fabric is provided between the top of the folding control plate transition arc and the lower side of the upper plane of the folding position control groove; the left end of the folding control plate surface is tangent to the lower end of the folding control plate transition arc; the right side of the folding control plate surface extends to be tangent to the upper end of the transition arc of the outer edge control groove of the folding distance; the folding control plate surface is parallel to the lower plane of the second folding position control groove; the folding control plate transition arc and the transition arc together control the folding amount of the second fold of the home textile product.

[0011] Furthermore, the first folding slot, the second folding control slot, the folding distance outer control slot, and the folding control plate are made of stainless steel and are free of burrs.

[0012] Compared with existing technologies, the pull tube of this invention is used by attaching its bottom surface to the sewing machine table with double-sided strong adhesive. This ensures the distance between the pull tube and the needle meets the process requirements for folding amount and edge distance of home textile products. The patchwork pieces are then sequentially inserted into the folding distance outer edge control groove, the second folding position control groove, and the first folding position slot. The sewing machine motor is then started to sew the patchwork. The transition arc of the folding control plate and the transition arc work together to control the folding amount of the second fold of the home textile product. This invention ensures that the distance between the two folding positions, the folding amount, and the patch width precisely meet the process requirements, resulting in stable quality, simple operation, and convenient adjustment. This improves the product quality and production efficiency of folded patchwork. Attached Figure Description
