Description

Technical Field

[0001] The utility model relates to the technical field of clothing production equipment, in particular to a cloth cutting and trimming device for clothing production. Background Art

[0002] The production of underwear involves multiple processing steps, such as early fabric gluing, initial shaping of underwear, mid-term trimming and cutting, hot pressing, and later breast pad filling to underwear shaping. Among them, after the fabric is glued and initially formed, it usually leads to uneven fabric sizes and excess fabric on the edge of the underwear. At this time, the fabric needs to be trimmed so that subsequent production can meet unified standard requirements.

[0003] After searching, it was found that the publication number is CN213804543U, and the name is a cloth trimming device. The application proposes that in the prior art, especially for smaller enterprises, in order to save costs, manual trimming is sometimes used. Manual trimming is not only very inefficient, but also has many human factors. The qualified rate of products is usually low. As for the use of intelligent and mechanized trimming equipment, although this equipment can achieve more standardized production, its cost is high, the structure is complex, and the operation and maintenance cost is high, which is still not conducive to the production needs of small enterprises. Cutting and trimming are performed by applying pressure with a pressing plate, but this method still requires a large number of manual loading and unloading operations, and the working process is discontinuous, the interruption time is long, and the work efficiency is low. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0032] In one embodiment, a perforated plate 15 is fixedly connected to one end of the exhaust pipe 5 near the shaft tube 6, and the perforated plate 15 is ventilated, and a blocking ball 13 is connected to the other side surface of the perforated plate 15 through a spring 14, and a blocking seat 10 is fixedly connected to one end of the exhaust pipe 5 near the negative pressure chamber 3, and a ball groove 11 is provided on the surface of the blocking seat 10 corresponding to one end of the blocking ball 13, and a vent hole 12 is provided between the ball groove 11 and the other end surface of the blocking seat 10, and the vent hole 12 is convenient for airflow to pass through.

[0037] Working principle:

[0038] When cutting and trimming the cloth, the staff can start the stepper motor 19 and the air pump 18. The air pump 18 extracts the air inside the shaft tube 6 through the air rotating connector 16, and then extracts the air inside the negative pressure chamber 3 through the air suction pipe 5, so that the top hole 4 is in a negative pressure suction state. The staff can place the clothing cloth to be cut and trimmed on the top surface of the negative pressure chamber 3 on one side of the door frame 1. The top hole 4 sucks the clothing cloth. The stepper motor 19 drives the shaft tube 6 to rotate, and then drives the rotating disk 2 to rotate, drives the cloth to rotate to the bottom of the trimming knife 9, and the cylinder 7 extends to push the trimming knife 9 downward for cutting and trimming. The device continuously rotates the rotating disk 2 in a step-by-step manner, and cooperates with the lifting of the trimming knife 9. Continuous cutting and trimming are carried out with high working speed, easy use, high working continuity and improved work efficiency. At the same time, when the exhaust pipe 5 is rotated to tilt downward, the blocking ball 13 located inside the exhaust pipe 5 is moved to the ball groove 11 opened on the surface of the blocking seat 10 by gravity, and gradually blocks the air hole 12 as the exhaust pipe 5 rotates, so that the exhaust pipe 5 located at the bottom of the rotating disk 2 is in a closed state, and the negative pressure bin 3 located at the bottom of the rotating disk 2 no longer generates negative pressure, and the fabric that has been cut and trimmed on the surface of the negative pressure bin 3 falls off, thereby completing automatic unloading and separation, eliminating the trouble of manual unloading, and further improving the convenience of use and work efficiency.
