Yarn-passing device of embroidery machine

Abstract

The invention discloses a yarn-passing device of an embroidery machine, which comprises a base, wherein the base comprises a bottom plate and a face plate, the middle of the face plate is bulged outwards, both sides of the face plate are connected to the bottom plate, and a hollow cavity is formed between the face plate and the bottom plate; a plurality of yarn-passing assemblies are arranged in the cavity and respectively comprises a holding plate arranged on the bottom plate, the front sides of the holding plates extend out of the cavity from the face plates, and both sides of the holding plates, passing through the face plates, are provided with yarn-passing slots; and a tension regulator is arranged on one of the side face of the holding plates, and a take-up spring is arranged on thetension regulator and is provided with a tension spring end sleeved on the tension regulator and a take-up hook end extending out of the tension regulator. The whole yarn-passing device is a claddingbody; all assemblies are covered in the base so that the operators can not touch the moving parts of the yarn-passing device, thereby not resulting in part damages and personnel injuries.

Description

technical field [0001] The invention relates to the technical field of thread passing devices for embroidery machines, in particular to a thread passing device for embroidery machines. Background technique [0002] The more advanced intermediate thread of the existing embroidery machine, such as figure 1 and figure 2 As shown, this structure is also used in Chinese patent ZL200710070827, which mainly includes upper panel 101, U-shaped seat 102, tension adjustment handle 103, anti-slip sheet 104, thread take-up spring 105, thread take-up lever 106, roller 107 And over-the-line ceramic 108. [0003] Embroidery thread passes in the hole under two rollers 107, then passes in the thread take-up spring 105, then returns in the hole under the roller 107 and goes out, penetrates the thread take-up lever 106, and then passes thread ceramics 108. U-shaped seat 102 is fixed on the upper panel 101, and tension adjustment handle 103 adjusts thread take-up spring 105 to move up and do...

AI Technical Summary

Problems solved by technology

[0004] With the development of embroidery machines, the number of heads and needles has increased greatly. The number of heads can reach 64, and the number of needles can reach 12 needles. Threading is very cumbersome

The anti-slip sheet 104 is easy to wear when the tension adjustment handle 103 is continuously adjusted, and it cannot fix the thread take-up spring 105. When using this kind of intermediate thread, it can only be equipped with a flat upper panel 101, resulting in most of the thread take-up lever 106. If it is exposed outside, when the thread take-up lever 106 moves up and down, it is easy to cause injury to the operator and is not safe enough

The thread take-up spring 105 is also exposed outside and is easily bent or broken when touched, causing damage to the middle thread and making it unusable

The tension adjustment handle 103 rotates and adjusts the thread take-up spring 105 of all stitches to go up and down together, but cannot be adjusted independently, resulting in that the tension adjusted in the previous stitch is not applicable to the next stitch and needs to be readjusted, and it needs to be readjusted when returning to the previous stitch. Increased workload and affected the stability of embroidery work
