Problems solved by technology

[0002] When the sewing machine sews long threads (such as curtains, bedding, etc.), in the process of splicing and curling, the length of a single sewing thread is more than 2.5 meters. With ordinary sewing methods, there will be irregularities at the end of sewing. , if you use people to pull it in the back, you need two people to sew a thread, and the labor cost doubles
Moreover, it cannot maintain a consistent tension, and there will be uneven sewing tension.
When sewing large items such as curtains and bedding, due to the weight of the fabric, it will be very laborious for the sewing worker to move and fold the fabric, and the work will be labor-intensive

Embodiment Construction

[0017] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0018] Such as Figure 1-4 Said sewing device includes a frame 11, a sewing machine 1 supported on the frame 11, and a tension mechanism on the feeding side of the sewing machine 1. The tension mechanism is used to align the stitching edges of the two cloths to be stitched and has a certain pre-tightening force (tension), and the pre-tightening force keeps the two stitching edges aligned before sewing.

[0019] Specifically, the tension mechanism includes a guide rail 6 supported on the frame 11 along the feeding direction, a slider 61 matched with the guide rail 6, and a clamping mechanism 7 fixed on the slider 61. The slider 61 can Relative to the guide rail 6 sliding along the feeding directio...

Abstract

The invention discloses a sewing device. The sewing device comprises a rack, a sewing machine supported on the rack and a tension mechanism positioned at the feeding side of the sewing machine and used for making a stitching edge of a material to be stitched have certain pre-tension force; the tension mechanism comprises a guide rail supported on the rack in a feeding direction and a clamping mechanism arranged on the guiding rail in a sliding mode and used for clamping one end of the stitching edge tightly. The sewing device can ensure the pre-tension force performed on the stitching edges during stitching, make the stitching edges always maintain flush and reduce the stitching cost.

Description

Technical field [0001] The invention relates to the field of sewing machines, in particular to a sewing device with a back tension mechanism. Background technique [0002] When sewing long threads (such as curtains, bedding, etc.) on the sewing machine, in the splicing and hemming process, the length of a single sewing thread is more than 2.5 meters. With ordinary sewing methods, it will be uneven at the end of sewing. If you use people to pull it later, two people are needed to sew a thread, and the labor cost doubles. Moreover, the continuous tension cannot be maintained, and uneven sewing tension will occur. When sewing large items such as curtains and bedding, due to the heavy fabrics, the sewing workers will be laborious and labor intensive when moving and stacking the fabrics. Summary of the invention [0003] The main purpose of the present invention is to provide a sewing device, which realizes the alignment of the two-belt sewing cloth on the sewing side through a back ...
