Description

Technical Field

[0001] The utility model relates to the technical field of cloth cutting equipment, in particular to a full-automatic cloth strip cutting machine. Background Art

[0002] The cloth strip cutting machine is specially made for cutting knitted strips. In actual use, it is often necessary to adjust the different height fixing positions of the guide roller to cope with the different tensioning requirements of fabrics of different sizes. Most of the cloth strip cutting machines on the market fix the height position of the support roller by manually adjusting the nut. In addition, in order to ensure that the manual adjustment nut has a certain pre-tightening force and does not cause the support roller to slip, the height position of the support roller has to be adjusted manually by tightening and loosening the manual adjustment nut each time. Therefore, a fully automatic cloth strip cutting machine is designed.

[0003] The utility model patent with publication number CN211142612U discloses a fully automatic cloth strip cutting machine for clothing production, including a frame, a workbench, a transmission roller, a support plate, a winding roller, a shearing saw blade, a support rod, a "T"-shaped bottom plate, a first drive motor, a second drive motor, a third drive motor and a control panel. The side of the frame is fixedly connected with the "T"-shaped bottom plate, the frame is slidably connected to the support rod through a vertical circular hole provided inside, the lower half of the support rod is provided with a thread, the upper end of the support rod is fixedly connected with the workbench, a side of the workbench is fixedly connected with the support plate, and the first drive motor, the second drive motor and the third drive motor are fixedly installed inside the workbench. The utility model arranges the cloth into a cylindrical shape and is sleeved on the transmission roller and the guide roller to achieve continuous cutting of the cloth. At the same time, an adjustable guide roller is provided to meet the needs of cloth of different sizes. The workbench lifting structure is designed to adjust the height of the workbench for easy operation by users. However, the above patent still has certain defects. The patent is provided with an adjustable guide roller to meet the needs of cloth of different sizes. At the same time, the tension of the cloth can be adjusted by the guide roller. When the tension of the cloth is adjusted, the staff needs to support the cloth to avoid the cloth from being skewed, which causes the cut cloth to not meet the standards. Every time the tension is adjusted, other staff are needed to help support and position the cloth. The operation is relatively complicated and requires the cooperation of multiple people, resulting in low work efficiency. Utility Model Content

[0032] The working principle of the above embodiment is:

[0033] (1) When placing the cloth on the first guide roller 5, the cloth is placed in contact with the first guide roller 5, and then the two pressing rollers 407 are pulled upward. The pressing roller 407 drives the fixed plate 406 to move upward through the rotating rod 408. At the same time, the fixed plate 406 pulls the movable plate 409 upward through the connecting plate 405, and the movable plate 409 pulls the rope to compress the spring 410 upward. Then, the cloth is passed between the first guide roller 5 and the pressing roller 407, and the position of the cloth is adjusted and the cloth is tightened at the same time. Then, the pressing roller 407 is released, and the compression spring 410 pulls the connecting plate 405 downward through the movable plate 409. As the connecting plate 405 moves downward, the fixed plate 406 passes through The rotating rod 408 drives the pressing roller 407 to move downward, and the pressing roller 407 fits with the cloth through the outer rubber sleeve and presses it to the cloth, so that the cloth can only move along the rolling direction of the pressing roller 407. The pressing mechanism 4 presses the cloth on the first guide roller 5 through the cooperation of the connecting box 402, the connecting plate 405, the fixed plate 406, the pressing roller 407, the rotating rod 408, the movable plate 409 and the pressing spring 410, so that the cloth is difficult to move left and right and can only move along the rotation direction of the pressing roller 407 and the first guide roller 5, so that when the tension of the cloth is adjusted, there is no need for the staff to support it to ensure that the position of the cloth is not offset.

[0034] (2) After the cutting device is started by the control box 1, the second electric push rod 203 is started. The second electric push rod 203 drives the shielding box 201 to move downward through the output shaft, and the slider 204 moves downward together with the shielding box 201. When the slider 204 slides to the bottom of the slide slot, the second electric push rod 203 is closed. At this time, the shielding box 201 is not in contact with the support plate 3, and the distance between the shielding box 201 and the support plate 3 is such that the cloth can pass through. The protection mechanism 2 covers the cutting blade of the cutting device inside through the cooperation of the shielding box 201, the fixed box 202, the second electric push rod 203 and the slider 204, and at the same time leaves enough space for the cloth to pass through, thereby avoiding the problem of workers being injured due to accidental touching of the cutting blade, thereby ensuring the safety of workers when the equipment is running.

[0035] Of course, the above are only preferred implementations of the present utility model, and are not intended to limit the scope of use of the present utility model. Therefore, any equivalent changes made to the principles of the present utility model should be included in the protection scope of the present utility model.
