Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to an auxiliary feeding mechanism for a plate sewing machine. Background Art

[0002] Textile refers to the processing of natural or chemical fibers into various yarns, silks, ropes, fabrics and their dyed products. A variety of equipment is needed in the textile process. A sewing machine refers to a machine used to sew the collar of a sweater. Before work, it is necessary to manually insert the strips of cloth into the needle disk one by one for manual loading. In order to improve the convenience of loading, an auxiliary loading mechanism is usually used.

[0003] At present, when using an auxiliary feeding mechanism, there is a lack of a quick positioning mechanism. Usually, when performing a feeding operation, the cloth strip needs to be inserted into the needle plate of the sewing machine. However, the repeated pressing and inserting feeding operation takes a long time and has a low efficiency, resulting in a mediocre feeding effect. Therefore, an auxiliary feeding mechanism for a sewing machine is proposed to increase a quick positioning mechanism. Before the cloth strip is fed, its end is pre-limited quickly, and then it is pushed and inserted into the needle plate of the sewing machine at one time, thereby improving the use effect.

The structure is simple and easy to operate, and the use is more convenient and efficient.

[0033] In order to improve the flexibility of auxiliary feeding, for example, Figure 2 , Figure 4 As shown, the utility model also includes that the guide assembly 3 includes a fixed frame 301, the surface of the fixed frame 301 is provided with an arc-shaped slide 302, a sliding block 303 is slidably connected in the arc-shaped slide 302, and an arc-shaped air cushion 304 is connected to one side of the sliding block 303 in the arc-shaped slide 302 by gluing.

[0034] When in use, the arc-shaped air cushion 304 is connected to an external air pump to inflate and deform, which can push the sliding block 303 and the limiting component 4 to move a fixed length, so as to facilitate the adjustment of the feeding range of cloth strips of different sizes. It has a simple structure, low cost, and is more flexible and reliable to use.

[0035] For example, Figure 3 As shown, the utility model further includes that a magnetic block 407 is installed on the inner side of the clamping plate 402 through a slot, and an electromagnet 408 corresponding to the magnetic block 407 is arranged on the inner side of the sliding frame 401 .
