Generally, school uniforms have the school emblem of the school, which also directly affects the school image. In the clothing production industry, especially during the production process of school uniforms, a corresponding waist-pulling machine is generally used to perform waist-pulling processing on school uniform fabrics.

[0003] For example, the utility model patent with the application number 202222186210.7 discloses a waist-pulling machine with an automatic cloth-receiving mechanism, which includes a waist-pulling machine main body.

A connecting sleeve is installed at the output end of the driving motor. A retaining disc is installed at one end of the outer part of the connecting sleeve. A sliding shell is slidably installed on the outer part of the connecting sleeve.

[0004] Based on the prior art, it is found that most of the existing waist-pulling machines have a single structure. Although they can automatically wind up the fabric after waist-pulling processing, they cannot properly limit the fabric during the fabric winding process, resulting in the problem that the fabric is prone to skew and deviation during the winding process, which is inconvenient to use. Moreover, they cannot flatten the fabric before winding, resulting in the fabric being prone to wrinkles, thus affecting the fabric quality and having low practicability. Therefore, the utility model proposes a waist-pulling machine for making school uniforms to solve the problems existing in the prior art. Summary of the Utility Model

Second fixing frames 7 are provided on both the front and rear sides of the first fixing frame 3 and are bolted to the top of the machine table 1. Limiting plates 8 driven by a rotation driving mechanism to displace are arranged on both the left and right sides inside the second fixing frame 7. The fabric is limited and guided by the left and right groups of limiting plates 8. The two groups of limiting plates 8 inside the second fixing frame 7 are driven by a rotation adjustment mechanism to move towards or in opposite directions, and the two groups of limiting plates 8 are moved to appropriate positions according to the width of the fabric, so as to effectively limit the fabric during the winding process of the school uniform processing fabric, and can avoid the problem that the fabric is prone to skew and deviation during the winding process.

[0021] The rotation driving mechanism includes a lead screw 9 and a turntable 10. Among them, two groups of lead screws 9 are provided and threadedly penetrate through the left and right side walls of the second fixing frame 7.

[0023] The rewinding mechanism includes a fixed plate 16 and a rewinding roller 17. There are two groups of fixed plates 16, which are symmetrically fixed to the outer wall of the rear side of the machine table 1 by bolts.
