Description

A tensioning machine used for clothing production

Technical field

The invention relates to the technical field of clothing machinery, in particular to a tensioner used for clothing production.

Background technique

In the clothing production process, textiles need to be cut. Before cutting, the entire roll of cloth needs to be pre-spread. When spreading, pre-tensioning is required to prevent the cloth falling on the worktable from wrinkling.

Chinese patent CN201420407334.6 discloses a feeding tensioning mechanism for clothing cutting equipment, including a mounting seat, two feeding rollers arranged side by side on the mounting seat, and at least two parallel and horizontal tensioning rollers. , At least two feed rollers arranged parallel to each other and horizontally and a drive assembly that drives the tension roller to move laterally so that the tension roller and the feed roller are alternately arranged in the vertical direction; the two feed rollers rotate in the same direction and are separated from each other , The feeding roller is arranged below the mounting seat, the tension roller is arranged on one side of the feeding roller, the tension roller and the feeding roller are adjacent to each other in pairs, are parallel to each other, and rotate in opposite directions, wherein the drive The assembly is composed of a runner, a gear, and a connecting frame. The three tension rollers are rotatably arranged on the connecting frame, and the runner is drivingly connected with the gear (that is, the rotating wheel can drive the gear to rotate), and the connecting frame corresponds to The gear is provided with a rack, and the gear is meshed with the rack for transmission. When the fabric is conveyed to the lowest feeding roller, the worker can control the pressing mechanism to move to the left through the forward rotating wheel to compress the fabric, and then fix the rotating wheel. The operation is easy and very convenient. After the piece of fabric is tensioned and transported, the worker can move the pressing mechanism to the right away from the feed roller by using the reversing wheel to prepare for the feeding of the next piece of fabric.

In the above-mentioned patent documents, the manual rotation of the runner is used to drive the gear to rotate, which in turn drives the rack to move to realize the movement of the pressing mechanism. In this process, there are two problems. One is that the manual rotation of the runner is required, which will increase Labor, slow efficiency, and inconvenient to use; second, the movement of the pressing mechanism is realized through the transmission of gears and racks. During the movement, it is difficult to ensure the stability of the movement of the pressing mechanism, and thus it is difficult to guarantee the tension roller and the feeding roller. The relative position between them, and thus the position of the cloth cannot be precisely adjusted.
