Embodiment 1

[0044] Embodiment 1: Reference figure 1 , is a kind of synchronous overlock sewing device for an elastic belt applied to a sewing machine disclosed by the present invention, comprising a machine platform 1, a sewing machine body 11 fixed on the upper side of the machine platform 1, and a vertically arranged thread needle 12 is installed on the sewing machine body 11. The upper side of the machine table 1 is also equipped with a wrapping mechanism 3 positioned at the feeding side of the thread needle 12, a pulling mechanism 4 positioned at the discharging side of the thread needle 12, a tensioning mechanism 2 positioned at the front end of the wrapping mechanism 3, and a tension mechanism positioned at the front end of the wrapping mechanism 3. The transition frame 21 above the tight mechanism 2. The elastic band passes through the transition frame 21, the tensioning mechanism 2, the wrapping mechanism 3, and the pulling mechanism 4 in turn. The elastic band contacts the cloth ...

Embodiment 2

[0057] Embodiment two: reference Figure 9 , this embodiment only adds a protection strip 8 and a protective cover 81 on the basis of the first embodiment.

[0058] The protective strip 8 is fixedly connected to the end of the guide strip 7 close to the thread needle 12, and the protective strip 8 is hollowly provided with a protective passage 82 along its length direction, and the protective passage 82 is connected to the guide passage 71; the end of the protective strip 8 away from the guide strip 7 extends to the wire Needle 12 discharge side. The protective sheath 81 is fixedly connected to the end of the wrapping sheath 62 close to the thread needle 12, and the end of the protective sheath 81 away from the wrapping sheath 62 extends to the discharge side of the thread needle 12; the protective sheath 81 is penetrated with a needle hole 83 from top to bottom.

[0059] The implementation principle of this embodiment is: by being provided with the protective strip 8 and the...

Abstract

The invention relates to an elastic belt synchronous overlock device applied to sewing machines, and relates to the technical field of knitting. Due to the high difficulty and low efficiency of the existing overlock operation. This scheme includes a machine table, a sewing machine body fixed on the upper side of the machine table, a vertical thread needle is installed on the sewing machine body, a wrapping mechanism on the feeding side of the thread needle is installed on the upper side of the machine table, a The pulling mechanism on the side of the material; the wrapping mechanism is used to wrap the edge of the fabric to the outer circumference of the elastic band, and the pulling mechanism is used to continuously transport the finished products that have been stitched and edge-locked backwards. Through the above operations, the continuous overlock operation of the elastic band can be realized, so as to improve the efficiency and reduce the difficulty of operation.

Description

technical field [0001] The invention relates to the technical field of knitting, in particular to an elastic belt synchronous overlock sewing device applied to a sewing machine. Background technique [0002] In the knitting industry, sewing machines are very common equipment. In the processing of certain products, it is necessary to sew the elastic band to the edge of the low-elastic fabric, so that the edge of the fabric has a certain degree of flexibility, which can be processed into a closed end in the later stage. cloth bags, or other products. [0003] In the existing processing method, it is usually necessary for the operator to wrap a short section of elastic band with cloth first, and then carry out the overlock operation of this short section of elastic band, and if the overlock operation of a long elastic band is to be completed, it is necessary to reciprocate the above operation several times , the operation difficulty is high, and the efficiency is extremely low...
