Description

Technical Field

[0002] In the cutting process of protective clothing fabrics, positioning is a key link. Accurate positioning can ensure the accuracy and efficiency of cutting, avoid fabric waste and cutting errors. The winding function is the process of arranging, winding and storing the cut fabrics. A good winding effect can ensure the flatness and tightness of the fabrics, which is convenient for subsequent processing and use.

[0003] After searching, a Chinese patent with publication number CN218695018U provides a clothing cutting, positioning and pressing device. The device is provided with a flattening device and a pressing device. The cloth is placed on a workbench and passed through the bottom of a pressing plate and the bottom of a movable roller. When the winding device winds the cloth, the movable roller presses one side of the cloth under the action of a second spring, and the bottom end of the pressing plate presses the other side of the cloth under the action of a telescopic rod and the elastic force of a first spring. Thus, the cloth is wrinkled under the action of the pressing plate and the cloth is completely flattened on the workbench, avoiding the cloth from shaking during the cutting process.

[0022] Beneficial effects of the utility model:

[0023] 1. The labor insurance clothing fabric body is transported by the conveyor, and the piston rod of the first cylinder pushes the movable block to slide along the C-shaped block, driving the movable sleeve to slide along the C-shaped block, so that the roller shaft rotates along the movable block, and the two ends of the roller shaft rotate along the positioning block.

When the labor insurance clothing fabric body is cut by the laser cutting machine, the conveyor stops rotating, and the piston rod of the first cylinder pushes the bottom surface of the movable block to abut against the top surface of the labor insurance clothing fabric body. At this time, the first spring is compressed, so that the roller shaft is located at the limiting groove. At the upper end of the positioning slot, after the protective clothing fabric body is positioned, the first screw is driven by the output shaft of the forward and reverse motor to rotate along the fixed block, and the push block is pushed to drive the gantry to slide along the slide rail and the top surface of the conveyor. At the same time, the second screw is driven by the output shaft of the first servo motor to rotate along the connecting block, and the slider is driven to slide along the gantry, so that the laser cutting machine moves to the appropriate position to cut the protective clothing fabric body. After the cutting is completed, the movable block is separated from the protective clothing fabric body, which facilitates the continuous transportation of the protective clothing fabric body, accurately positions the fabric, improves the accuracy and efficiency of laser cutting, and facilitates the seamless connection between the continuous transportation and cutting of the fabric.

[0024] 2. The second servo motor drives the rotating shaft to rotate along the support, so that the rotating shaft drives the helical teeth of the worm to rotate, and the helical teeth of the worm are meshed and transmitted to the worm wheel to rotate, so that the worm wheel drives the rotating rod to drive the rotating wheel to rotate synchronously. At this time, the worm wheels on both sides of the middle support will rotate in opposite directions, and the labor protection clothing fabric body between the conveyor and the winding component will be unfolded from the middle to both sides, reducing the occurrence of wrinkles when the fabric is wound, reducing inaccurate cutting and winding problems caused by fabric deviation or fluctuation, helping to eliminate wrinkles and unevenness on the fabric, and improving the overall quality and appearance of the final product.

[0025] 3. Insert the reel onto the winding roller, rotate the reel along the winding roller by tightening the hand wheel to abut the reel, and then push the second spring and the adjusting block toward the winding roller through the piston rod of the second cylinder, so that the adjusting block drives the positioning roller to abut against the labor protection clothing fabric body on the outer wall of the reel, and the winding motor drives the rotating reel to reel the labor protection clothing fabric body.

The bottom surface of the piston rod of the first cylinder 504 is fixedly connected to the top surface of the C-shaped block 503, and two movable sleeves 505 are fixedly provided on the movable block 501 in a symmetrical structure. The movable sleeves 505 are sleeved on the C-shaped block 503, and the movable sleeves 505 are slidably connected to the C-shaped block 503; the piston rod of the first cylinder 504 pushes the bottom surface of the movable block 501 to abut against the top surface of the labor protection clothing fabric body 2.

At the same time, the output shaft of the first servo motor 9 drives the second screw rod 16 to rotate along the connecting block 17, driving the slider 15 to slide along the gantry 3, so that the laser cutting machine 4 moves to a suitable position to cut the protective clothing fabric body 2.
