Description

Technical Field

[0001] The utility model belongs to the technical field of geotextile production, and in particular relates to geotextile cutting equipment. Background Art

[0002] Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. Geotextile is one of the new geosynthetics. The finished product is in the shape of cloth, generally 4 to 6 meters wide and 50 to 100 meters long. The functions of geotextile include isolation, filtration (reverse filtration), drainage, reinforcement, protection, and puncture prevention. The characteristics of geotextile include high strength, corrosion resistance, good permeability, and good anti-microbial properties.

[0003] In the manufacturing process of geotextile, cutting of geotextile is the last step. After this step, the geotextile can be used. At present, the cutting of geotextile has been completed by automated equipment. Different customers require geotextiles of different specifications. Some geotextiles need to be cut twice, horizontally and vertically, to meet customer specifications. However, the current equipment can only complete one cutting at a time, and the second cutting can only be clamped twice, which has low production efficiency and high cost. Utility Model Content

[0004] The purpose of the utility model is to provide a geotextile cutting device to solve the above-mentioned technical problems, so as to improve the production efficiency and ensure the cutting accuracy.

[0005] In view of this, the utility model provides a geotextile cutting device, comprising:

[0008] A second cutting assembly, the second cutting assembly being used to synchronously cut each fabric strip in a transverse direction;

[0009] A cloth pushing assembly, the cloth pushing assembly is used to carry the cloth for transmission and discharge the cloth from the cloth discharge roller;

[0010] Among them, the first cutting component and the second cutting component are arranged front and back along the cloth transmission direction, the cloth pushing component is arranged between the first cutting component and the second cutting component, the cloth pushing component is used to transfer the cloth cut by the first cutting component to the second cutting component, and a limiting component is also arranged between the first cutting component and the second cutting component, and the limiting component is used to limit the width direction of each cloth strip cut by the first cutting component.

When the cloth-pushing cylinder piston is extended first to press the pushing block on the cloth strip, and then the slider moves the cloth-pushing rod along the cloth-transmission direction to feed the cloth into the second cutting assembly.
