Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of fabric processing device relates to a composite fabric processing edge compression device. BACKGROUND

[0002] The basic function of a sewing machine is to sew fabric together with a needle and thread. In composite fabric processing, one of the important purposes of edge compression is to fix the edges of the composite fabric to prevent the edges from delaminating and spreading out. A sewing machine can use a needle that moves up and down and a bobbin that rotates to thread the edge of the composite fabric with thread, achieving edge compression in a sewing manner.

[0003] When the composite fabric enters the area below the presser foot of the sewing machine, it may bring its own wrinkles or new wrinkles caused by the conveying process into the sewing area, causing the wrinkles to be sewn into the edges after edge compression, affecting the overall flatness and appearance quality of the composite fabric, and being not conducive to subsequent processing and use. For example, when making clothes, uneven edges may affect the comfort and aesthetics of wearing. SUMMARY

[0004] The utility model aims at the above problems existing in the prior art, and provides a composite fabric processing edge compression device that ensures the flatness and aesthetics of the fabric.

[0005] The utility model can achieve the above-mentioned purposes through the following technical solutions.

[0007] In the above-mentioned composite fabric processing edge compression device, the lower ends of the two spring members are fixedly connected with a connecting horizontal plate, and the connecting horizontal plate is fixedly connected between the two vertical connecting rollers.

[0008] In the above-mentioned composite fabric processing edge compression device, a plurality of mutually connected positioning inner holes are formed in the inner end of the connecting horizontal plate and the outer end of the extended inner horizontal rod, and the corresponding positioning inner holes are arranged equidistantly from top to bottom.

[0009] The plurality of horizontal positioning holes are inserted with a plug anti-off crossbar.

[0010] The lower end of the extension inner crossbar is fixedly connected with a strip-shaped laser emitter, and the two strip-shaped laser emitters are cooperated with each other.

[0011] The two limiting guide pressing rollers are respectively located at the front and rear ends of the presser bar, and the fabric processing table top is placed with a composite fabric body at the upper end.

[0012] The composite fabric body is located below the presser bar and the two limiting guide pressing rollers.

[0013] Compared with the prior art, the composite fabric edge processing device can set limiting guide pressing rollers on both sides of the presser bar when processing the edge of the composite fabric body. The limiting guide pressing rollers are horizontally arranged between the presser bar and the limiting guide pressing rollers. When the composite fabric body enters below the presser bar, the two limiting guide pressing rollers contact and press the fabric. Due to the rolling action of the limiting guide pressing rollers, the composite fabric body can be preliminarily flattened, which is very important for the composite fabric body that may have wrinkles, curling or local unevenness. At the same time, the pressing of the limiting guide pressing rollers can assist in guiding the composite fabric body to the sewing position below the presser bar, ensuring that the composite fabric body enters according to the predetermined path and speed, thereby ensuring the edge pressing and sewing operation effect of the composite fabric body. At the same time, the position of the limiting guide pressing roller can be adjusted by the spring between the connected cross plate and the upper slot, so that the position of the limiting guide pressing roller can be adjusted, and the use process is more flexible and widely applicable.
