Description

Technical Field

[0001] This utility model relates to the field of polyester fabric processing technology, specifically to a positioning device for cutting polyester fabric. Background Technology

[0002] Polyester fabric is a synthetic fiber obtained by spinning polyester, which is a polymer of organic dicarboxylic acid and diol. It is a high molecular compound with high strength and elastic recovery ability. It is durable, wrinkle-resistant, non-iron-pressing, and does not stick to lint. In the processing of polyester fabric, an auxiliary cutting mechanism is needed to cut the polyester fabric to facilitate subsequent sewing.

[0003] Chinese utility model CN219824704U discloses a "positioning fixture for cutting polyester fabric". In use, a fabric spreading roller is hinged to both sides of the processing plate. When in use, the fabric to be cut can be fed onto the surface of the processing plate through the fabric spreading roller.

Through the cooperation of the gear 22 and the tooth groove 121, the two moving frames 3 move towards or away from each other within the strip groove 11 on the cutting table 1. After adjusting the distance between the two moving frames 3, based on the width of the fabric, the upper end of the entire positioning column 431 is pulled upwards, causing the limiting ring 432 to compress the spring strip 441. When the positioning column 431 moves upwards within the limiting sleeve 415, the positioning column 431 no longer limits the first extension plate 412. At this time, the sliding block... 42, which can push the entire movable plate 41 to move laterally within the groove 32, thereby adjusting the spacing between multiple positioning mechanisms 4. When the spacing is adjusted, the pulling of the positioning column 431 stops, and the spring strip 441 begins to reset, pushing the limiting ring 432 to move downward, driving the pressing plate 45 at the lower end of the positioning column 431 to press the fabric. At the same time, the upper end of the positioning column 431 passes through the through hole 414 on the first extension plate 412 and extends into the positioning hole 33 at the top of the movable frame 3, thereby completing the limiting of the entire movable plate 41. This device is simple to operate and can adjust the spacing between the pressing mechanisms according to the actual situation, which greatly improves the pressing efficiency of the entire device on the fabric and ensures the subsequent cutting quality.
