During the production and processing of medical protective clothing, it is necessary to use a cutting knife to cut the protective clothing fabric near the line to form pieces of fabric, and then sew them according to the shape of the protective clothing.

[0003] During the production process of protective clothing, its fabric needs to be cut. During cutting, if the protective clothing fabric is not straightened, wrinkles are likely to occur, resulting in uneven or even deviations in the cuts of the protective clothing fabric after cutting, and ultimately even causing the produced protective clothing to be unqualified. Therefore, it is necessary to design a protective clothing fabric auxiliary cutting structure. Utility Model Content

[0023] The clamping mechanism includes a support plate 12, a pressure plate 9, a spring 7, a baffle 10 and a slide rod 22. The front end of the movable seat 24 and the upper end of the support frame 8 are fixedly connected to the support plate 12. The top ends of the two support plates 12 are fixedly connected to the slide rod 22. The top ends of the slide rod 22 are fixedly connected to the baffle 10. The circumferential surface of the baffle 10 is slidably connected to the pressure plate 9. The pressure plate 9 is located at the upper end of the support plate 12. A spring 7 is arranged between the pressure plate 9 and the baffle 10. The spring 7 is sleeved on the circumferential surface of the slide rod 22. One end of the spring 7 is fixedly connected to the baffle 10, and the other end of the spring 7 is fixedly connected to the pressure plate 9. During operation, the pressing plate 9 is pulled up along the sliding rod 22 to gradually expand the distance between the pressing plate 9 and the supporting plate 12. At this time, the spring 7 is compressed, and then one end of the protective clothing fabric is placed on the supporting plate 12, and the pressing plate 9 is released. At this time, under the action of the spring 7, the pressing plate 9 can be tightly pressed against the top of the supporting plate 12 to ensure that one end of the protective clothing fabric can be firmly located between the pressing plate 9 and the supporting plate 12, thus completing the function of pressing and fixing the protective clothing fabric. Then the third motor 21 is controlled to operate to drive the first threaded rod 6 to rotate. At this time, the moving seat 24 can drive the clamping mechanism at the right end to move right, so that the protective clothing fabric can be gradually straightened. Until the clamping mechanism on the right side moves to the right side of the working table 2, the protective clothing fabric is straightened. At this time, the lifting mechanism is controlled to operate to drive the working table 2 to move up, so that the working table 2 moves to the bottom end of the protective clothing fabric to support the protective clothing fabric, and then the cutting knife 5 can be used to cut the protective clothing fabric.

At this time, the mobile frame 3 drives the cutting knife 5 to move in the left and right directions, so that the cutting knife 5 can cut the protective clothing fabric at different positions in the left and right directions.

[0025] Furthermore, a sliding hole is provided on the upper end surface of the mobile frame 3, a sliding block is slidably connected inside the sliding hole, a first electric telescopic rod 4 is fixedly connected to the top of the sliding block, a cutting knife 5 is fixedly installed at the output end of the first electric telescopic rod 4, and the cutting knife 5 is located at the bottom end of the sliding block, and a second electric telescopic rod is fixedly connected to the rear end of the mobile frame 3, and the output end of the second electric telescopic rod is fixedly installed at the rear end of the sliding block. When working, the first electric telescopic rod 4 can drive the cutting knife 5 to move up and down, and the second electric telescopic rod can push the sliding block to move forward and backward along the sliding hole, thereby driving the cutting knife 5 to move forward and backward, so that it is convenient to use the cutting knife 5 to cut different positions of the protective clothing fabric in the front and back directions.

[0026] Furthermore, the lifting mechanism includes a second motor 17, a threaded cylinder 13, a second threaded rod 16, a driving wheel 18, a driven wheel 14, a first belt 15 and a second belt 19. The lower end of the base plate 1 is fixedly connected to the second motor 17 through a vertical plate, and the output shaft end of the second motor 17 is fixedly connected to the driving wheel 18.
