Description

Technical Field

[0001] The utility model relates to the technical field of clothing waist-drawing machines, in particular to a waist-drawing machine for jogging pants which can automatically adjust the size of the pants waist. Background Art

[0002] The jogging pants waist-stretching machine is a machine specially used for making and processing jogging pants. Its characteristic is that it can automatically adjust the size of the waist of the pants, without manual measurement and adjustment one by one, which greatly improves the work efficiency. The main function of this machine is to adjust the waist of the pants from loose to tight to the appropriate size, so that the jogging pants produced are more fit.

[0003] Prior art publication number CN219752648U discloses a waist-drawing machine, which belongs to the technical field of waist-drawing machine wires, and includes a support frame plate and a waist-drawing machine body. An adjustment device is arranged on one side of the waist-drawing machine body, and the adjustment device includes a fixed plate, a rotating handle, a threaded seat and a matching recessed seat. A guide block is fixedly installed on one side of the fixed plate, a long groove is provided on one side of the guide block, a wire hole is penetrated through one side of the guide block, and a connecting plate is fixedly installed on one side of the threaded seat. By being able to adjust the position of the rotating rod, it is convenient for the rotating rod to push the wire to move inside the long groove, and the tightness of the wire can be adjusted, which is convenient for processing the waists of various trousers and some skirts. At the same time, when the wire is pulled, the wire will drive the rotating rod to rotate, so that the rotating rod rotates in the middle of the matching recessed seat, thereby reducing the friction between the wire and the rotating rod, and eliminating the influence on the quality of the wire.

[0004] Although the above mentioned methods have certain advantages in improving the quality of the wire during processing, they still have certain disadvantages;
