Description

Technical Field

[0001] This utility model relates to the field of school uniform processing technology, specifically to an adjustment mechanism for a school uniform sewing machine. Background Technology

[0002] In the related technologies, in the garment processing industry, a coverstitch machine is an industrial sewing machine used to sew the edges or seams of clothing.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] Traditional cover-sewing machines often have some problems when processing school uniforms, such as the adjustment mechanism not being flexible enough to adapt to different sizes of school uniforms, resulting in low production efficiency; the clamping mechanism may not be able to hold the clothes stably during the sewing process, causing sewing deviations; and the operator has a high labor intensity during the adjustment and sewing process, and the school uniform is prone to getting stuck or damaged. Utility Model Content

[0005] The purpose of this invention is to provide an adjustment mechanism for a cover-sewing machine used in school uniform processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustment mechanism for a coverstitch sewing machine used in school uniform processing. This mechanism includes a sewing table and a mounting plate, with the mounting plate positioned on the side of the sewing table for easy operation and adjustment. Above the sewing table, a pressure plate and a sewing needle are mounted, with the sewing needle located in the center of the pressure plate. This design ensures the accuracy and stability of the sewing process.

[0007] The mounting plate is equipped with a fixed shaft and a longitudinal slide rail. The fixed shaft is driven by a drive motor, ensuring the continuity and efficiency of the sewing process. A fixed clamping roller is also installed on the fixed shaft to hold the uniform for stable operation during sewing. The longitudinal slide rail has a fixed ring and a moving block, which can slide freely on the longitudinal slide rail to adjust the tension and position during sewing.

[0008] The movable block is also equipped with a movable clamping roller, which works in conjunction with the fixed clamping roller to hold the school uniform, ensuring stability and precision during the sewing process. To further enhance the clamping effect, a high-strength spring is also installed between the movable block and the fixed ring. This spring can provide appropriate tension to ensure that the school uniform does not slip or deform during the sewing process.

[0009] Fixed and movable clamping rollers work together to clamp the school uniform and are located at the sewing output end of the sewing table, ensuring smooth sewing. To further improve the accuracy and stability of the sewing process, vertical guide rollers are also provided on the mounting plate to guide the school uniform pulled out by the fixed and movable clamping rollers, ensuring the correct position of the school uniform during the sewing process.

[0010] In addition, the mounting plate is equipped with a small longitudinal slide rail with a sliding movable plate. A test shaft is inserted into the movable plate, which abuts against the stretched school uniform to detect its tension and position. The test shaft is connected to a tension pneumatic clamp, which slides on the mounting plate for further adjustment of the uniform's tension. To ensure the accuracy of the sewing process, the tension pneumatic clamp is also equipped with a photoelectric sensor to monitor the slack of the vertical guide rollers, ensuring stability and precision during sewing.

[0011] Finally, to prevent the school uniforms from getting stuck during processing, the school uniform entry end of the pressure plate is equipped with an arc-shaped upturned end. This can effectively prevent the school uniforms from getting stuck or damaged when entering the sewing table, ensuring a smooth sewing process and the quality of the school uniforms.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by using the fixed shaft and the longitudinal slide rail in combination, the position of the clamping roller of the cover-sewing machine can be quickly adjusted to adapt to different sizes of school uniforms, thereby improving production efficiency.

[0013] The combined use of fixed and movable clamping rollers ensures that the school uniform is stably clamped during sewing, reducing sewing deviations caused by uniform movement and improving sewing quality. The vertical guide rollers effectively guide the pulled-out uniform, reducing operator workload and simplifying the process.

[0014] The combined use of a small longitudinal slide rail and a moving disc, along with a tension pneumatic chuck and photoelectric sensors, enables automatic detection and clamping of school uniforms, further improving the automation level of the coverstitch machine. The curved head design prevents school uniforms from getting stuck or damaged when entering the pressure plate, protecting the integrity of the uniforms.

[0015] The use of high-strength springs ensures that the moving clamping roller and the fixed clamping roller maintain appropriate clamping force, thus ensuring stability and sewing accuracy during the sewing process. Attached Figure Description
