Problems solved by technology

Some knitted fabrics weave the elastic band into the material, which is extremely elastic and in a state of elastic contraction in the free state, which brings a lot of inconvenience to the sewing work. If two different sizes and different elastic materials are stitched together, it is necessary to The elastic fabric that shrinks elastically is stretched by external force, so that it can be sewn with less elastic clothing material
The struts of the current support mechanism are rigidly connected. If the operator misuses or has insufficient operating experience, the support force of the fabric is adjusted too much, which may easily cause damage to the fabric.

Embodiment 1

[0019] Embodiment 1: As a preferred setting method of the limit mechanism, the rear end of the bracket 2 is set as a T-shaped stepped structure, and the limit mechanism is set on the base 1 by the first screw rod 51 and connected with the blind The hole 11 is connected with the first threaded hole 52. The first screw 51 is installed in the first threaded hole 52, and the rod body of the first screw 51 and the rear end of the bracket 2 are set as a T-shaped step-shaped structure. The surface is contacted and limited, and this embodiment has the advantages of simple structure and reliable use.

Embodiment 2

[0020] Embodiment 2: As another preferred setting method of the limit mechanism, the rear end of the bracket 2 is set as a T-shaped stepped structure, and the limit mechanism includes a second screw rod 61 and a screw on both sides of the blind hole 11. The second threaded hole 62, the locking pin 63 and the locking pin slot 64 arranged between the second threaded hole 62 and the blind hole 11, the second screw 61 is installed in the second threaded hole 62, the second The screw 61 is provided with a pin hole for the locking pin 63 to pass through. After the locking pin 63 passes through the pin hole of the second screw 61 and the locking pin groove 64, it is arranged with the rear end of the bracket 2 in a T-shaped stepped shape. The limit surface of the structure is used for contact limit, and this embodiment has the advantage of being able to adjust the elastic force of the spring 4 .

Abstract

The invention discloses an elastic support rod of a cloth expanding mechanism of sewing equipment. The elastic support rod comprises a base, a bracket, an expanding wheel, a spring and a limiting mechanism, wherein a blind hole is formed in the middle of the base; the spring is placed inside the blind hole in the middle of the expanding base; the rear end of the bracket is mounted inside the blind hole of the base; two ends of the spring are respectively propped against the bottom of the blind hole and the rear end of the bracket; the expanding wheel is mounted at the front end of the bracket through pins; the limiting mechanism is used for limiting the bracket from dissociating from the blind hole in the base. Due to the spring between the base and the bracket, the characteristic that the bracket has elastic floating is achieved, too large expanding force can be buffered and adjusted through the spring, and thus the situation that cloth is damaged because of the too large expanding force can be avoided.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of sewing equipment, and in particular relates to an elastic support rod of a material support mechanism of sewing equipment. [0003] Background technique: [0004] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. It is used for sewing necklines and cuffs of various elastic fabrics such as knitted underwear, sportswear, T-shirts, underwear, elastic bands for waist skirts, etc. Some knitted fabrics weave the elastic band into the material, which is extremely elastic and in a state of elastic contraction in the free state, which brings a lot of inconvenience to the sewing work. If two different sizes and different elastic materials are stitched together, it is necessary to External force stretches the elastically contracted elastic fabric so that it can be sewn with less el...
