Description

Technical Field

[0001] The utility model relates to the field of strip cutting, in particular to a strip cutting device for plastic weaving. Background Art

[0002] With the widespread application of plastic woven products in various fields, such as packaging (woven bags for fertilizers, grain, etc.), agriculture (shade nets, insect screens, etc.), and construction (geotextiles, etc.), the production efficiency and quality requirements for plastic woven products are constantly increasing. During the production process, it is often necessary to cut wide plastic woven materials into strips of varying widths to meet diverse product specifications. For example, in woven bag production, wide plastic woven fabrics need to be cut into strips of appropriate widths for bag handles or edge reinforcements.

[0003] The strip cutting device for plastic weaving usually includes a disc knife strip cutting device, a hot cutting strip cutting device and a braided belt slitting machine. The braided belt slitting machine is composed of a base, a feed roller, a cutting tool and a motor. When the feeding is started for the first time, in order to ensure that the braided belt can accurately enter the cutting area, the staff generally adopts manual feeding, manually feeds one end of the braided belt between the feed rollers, and then slowly rotates the feed roller so that the braided belt is gradually wound in by the feed roller.

[0004] In actual operation, it is necessary to pay attention to whether the braided belt moves forward correctly along the guide device. If there is any deviation, it should be corrected in time by adjusting the side guide plate. At the same time, the manual feeding method must not only ensure that one end of the braided belt remains flat when it enters the feed roller, but this process depends on the speed and proficiency of manual operation, which will take a lot of time, reduce the efficiency of the entire production process, and increase the workload and difficulty of the operator. In addition, during the operation, the operator's hand needs to be close to the feed roller. If not careful, it is very easy to cause injury to the operator. Utility Model Content

[0011] By adopting the above technical solution, the limiting plate can limit the braided belt so that the braided belt will not need to be manually pressed flat due to end warping or other inertia reasons. At the same time, it ensures that the braided belt enters the limiting plate smoothly, further ensuring that the braided belt enters the dividing area smoothly for striping.

[0012] Furthermore, the cross section of the guide block is designed to be an inclined surface, and the horizontal plane where the bottom of the guide block is located is close to the horizontal plane where the bottom of the roller is located, and the guide block is located in front of the roller.

[0013] By adopting the above technical solution, mutual interference between the guide block and the roller is avoided, ensuring that the guide block can smoothly guide the braided belt and the roller can squeeze the braided belt.

[0014] Furthermore, the width of the roller is consistent with the width of the limiting plate, and the roller is located at the end of the limiting plate, and the roller is close to the second feed port.

[0015] By adopting the above technical solution, it is ensured that the roller can squeeze the braided belt, ensuring that the braided belt can smoothly enter the second feed port, thereby realizing the segmentation of the braided belt.

[0016] Furthermore, the limiting hole corresponds to the limiting bead, and the position of the limiting hole corresponds to the strip grid on the outer wall of the split roller.

[0017] By adopting the above technical solution, the braided belt can correctly enter the width area that needs to be divided when being divided, thereby ensuring the accuracy of the braided belt dividing width and further improving the efficiency of the braided belt dividing.

[0018] In summary, the present invention has the following beneficial effects:

[0019] The utility model provides a limit plate, a guide block and a roller so that the limit plate can limit the braided belt, and can ensure that the braided belt maintains the correct position and width direction when entering the cutting area, and ensures that the braided belt enters the cutting area along a straight line. The limit plate limits and guides the braided belt, and can be used to separate braided belts of different widths. Under the action of the guide block and the roller, the braided belt enters the machine smoothly, reducing the occurrence of sudden movement or jamming of the braided belt, and at the same time improving the convenience of operation and the work efficiency.

At the same time, the limiting bead 8 arranged on the outer wall of the slide bar 401 moves into the limiting hole 7 to limit the clamping block 4. At this time, the clamping block 4 limits the woven belt. Since the side wall of the clamping block 4 is fixedly connected to the limiting plate 3, the limiting plate 3 limits the height of the woven belt downward. The two sides of the woven belt contact the outer wall of the clamping block 4. At this time, the woven belt is pushed so that the woven belt moves toward the second feed port 202. The guide block 5 guides the woven belt so that the end of the woven belt contacts the roller 6. The roller 6 rolls and feeds the woven belt into the second feed port 202, thereby causing the woven belt to enter the dividing roller 1, thereby realizing the woven belt stripping.
