Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a swing-arm electric flying knife cutting mechanism for cutting nets. Background Technology

[0002] In the processing of mesh or non-woven fabric products, the product segmentation process often relies on traditional manual blade cutting. This method requires precise manual operation to ensure the cutting effect, demanding high operator skill and suffering from low success rates, incomplete cutting, or material damage. Furthermore, manual cutting requires separate human monitoring of the process, consuming labor costs, and its efficiency is limited by the speed of manual operation, making it difficult to adapt to the high-efficiency production demands of modern equipment, thus limiting the overall production line capacity. Existing automated cutting mechanisms suffer from poor component coordination and require manual adjustment of material position, failing to achieve simultaneous stable material lifting and rapid cutting, further restricting the stability and efficiency of the cutting operation and failing to meet the industry's production requirements for high precision, high speed, and low reliance on manual labor in product segmentation.

A rodless cylinder is mounted on the inner wall of one of the support arms using a cylinder fixing plate. An electric cutter assembly is fixed to the movable end of the rodless cylinder using a bracket. The black steel round blade of the electric cutter assembly is movably arranged in the saw groove of the screen support plate.

[0005] Furthermore, the supporting surface of the support plate is located on the extension line of the tangent of the roller surface of the axial rubber roller assembly.

[0006] Furthermore, a nylon drag chain is connected to the bracket used to fix the electric cutter assembly via a tank chain fixing plate. The nylon drag chain is set in the tank chain fixing groove, which is installed on the square support.

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] like Figures 1-3As shown, this specific embodiment adopts the following technical solution: It includes two symmetrically arranged support arms 1 and a square support 5 installed between the support arms 1; both support arms 1 are mounted on the cutting blade shaft 4, and both ends of the cutting blade shaft 4 are mounted on the frame plates on both sides of the equipment using bearings 2. Large swing arms 3 are also rotatably mounted on both ends of the cutting blade shaft 4. The large swing arms 3 are also mounted on the frame plates on both sides of the equipment, and the large swing arms 3 are connected to the support arms 1 by a swing arm cylinder (the swing arm cylinder is not shown in the figure). A limit plate 13 is fixed on the inner wall of one of the support arms 1, and the limit plate 13 is connected to the cutting blade shaft 4 using a flat key 14; the limit plate 13 has a limit groove, which matches the limit block 15 fixed on the inner wall of the support arm 1; the end of the cutting blade shaft 4 A limiting shaft 16 is installed on the part, and the groove at the bottom of the limiting shaft 16 is engaged with the limiting end plate 17 fixed on the outer wall of the large swing arm 3. A spindle rubber roller group 6 and a screen support plate 12 are rotatably installed between the two support arms 1. A rodless cylinder 10 is installed on the inner wall of one of the support arms 1 using a cylinder fixing plate 9. An electric cutter group 11 is fixed to the movable end of the rodless cylinder 10 using a bracket. The black steel round blade of the electric cutter group 11 is movably set in the saw groove 12-1 of the screen support plate 12. The supporting surface of the screen support plate 12 is located on the extension line of the tangent of the roller surface of the spindle rubber roller group 6. A nylon drag chain 8 is connected to the bracket for fixing the electric cutter group 11 using a tank chain fixing plate 7. The nylon drag chain 8 is set in the tank chain fixing groove 18, which is installed on the square support 5.

[0017] In use, the swing arm cylinder extends, and the axial rubber roller group 6 presses the material to be cut onto the guide roller of the equipment. At the same time, the support plate 12 steadily supports the material to be cut. The motor in the electric cutter group 11 starts, and the rodless cylinder 10 starts, moving the circular cutter that is already rotating in the saw groove 12-1 from the leftmost to the rightmost. The circular cutter cuts the mesh or non-woven fabric products on the support plate 12. The swing arm cylinder retracts, driving the cutter shaft 4 to rotate, thereby driving the support arm 1 to rotate along the axis of the cutter shaft 4. Finally, the axial rubber roller group 6 and the support plate 12 are separated from the guide roller of the equipment. (In this utility model, the operation of the swing arm cylinder, the rodless cylinder 10 and the electric cutter group 11 motors are automatically controlled by the program, which can quickly and efficiently realize the cutting work.)

It can achieve 100% cutting of mesh or fabric products faster. Compared with the original manual cutting with blades, it improves the cutting success rate, saves labor, and improves the production efficiency of the equipment.

[0019] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
