Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a non-woven fabric edge cutting machine. Background Art

[0002] During the production of non-woven fabrics, shredded edges will appear on both edges. To ensure that both sides of the non-woven fabric are clean and flat, it is necessary to use an edge cutting machine to perform edge cutting on the edges of the non-woven fabric. However, during the edge cutting process of the existing non-woven fabric edge cutting machine, only one side edge of the non-woven fabric can be cut at a time. When it is necessary to cut both side edges, after cutting one side edge, it is necessary to perform edge cutting on the other side edge, which is rather troublesome. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the disadvantage that it is inconvenient to cut both side edges of the non-woven fabric simultaneously in the prior art, and to propose a non-woven fabric edge cutting machine.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] Design a non-woven fabric edge cutting machine, including a conveying roller and a mounting seat. A third telescopic rod is fixedly installed at the upper end of the mounting seat, and a lifting seat is fixedly installed at the upper end of the third telescopic rod. The conveying roller is rotatably arranged inside the lower end of the lifting seat. A first lead screw is rotatably installed inside the upper end of the lifting seat. A linkage block is threadedly sleeved on the outer side of the first lead screw. A first telescopic rod is fixedly installed at the lower end of the linkage block, and a cutting knife is fixedly installed at the lower end of the first telescopic rod. A flattening mechanism is fixedly installed on the lower surface of the upper end of the lifting seat.

[0006] Preferably, the flattening mechanism includes a second telescopic rod. A connecting frame is fixedly installed at the lower end of the second telescopic rod. A second lead screw is rotatably installed inside the connecting frame. A movable block is threadedly sleeved on the outer side of the second lead screw. The lower end of the movable block is slidably arranged inside the installation box. A connecting rod is fixedly installed on one side of the movable block. The end of the connecting rod penetrates and extends to the outside of the installation box and is fixedly installed with a pushing block.

[0007] Preferably, the lower surface of the pushing block is arc-shaped and fits the surface of the conveying roller. The bottom of the pushing block is made of a rubber structure.

[0008] Preferably, both the first lead screw and the second lead screw are bidirectional lead screws. The first lead screw and the second lead screw are parallel to each other and are both horizontally arranged.

[0009] Preferably, the lengths of the first telescopic rod, the second telescopic rod, and the third telescopic rod are all vertically arranged.

[0010] A non-woven fabric trimming machine proposed by the present utility model has the beneficial effects that during the working process of the non-woven fabric trimming machine, the second telescopic rod can drive the push block to move downward through the connecting frame and the mounting box, enabling the push block to contact the surface of the non-woven fabric. The second lead screw can drive the push blocks to move away from each other through the movable block. The push blocks during the moving-away process can unfold both sides of the non-woven fabric outward, flattening the wrinkled parts of the non-woven fabric. The third telescopic rod can drive the conveying roller to move up and down through the lifting seat, adjusting the tension degree of the non-woven fabric, making the non-woven fabric slightly taut and fitting on the surface of the conveying roller. The non-woven fabric in a taut state is more easily trimmed. The first lead screw can drive the linkage block and the cutting knife to move away from each other or move closer to each other simultaneously, and can adjust the specific position of the cutting knife according to the specific width of the non-woven fabric, enabling the trimming of non-woven fabrics with different widths.

Detailed Embodiments

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0017] Embodiment 1: Refer to Figures 1-4, a non-woven fabric trimming machine, including a conveying roller 1 and a mounting base 15. The mounting base 15 is fixedly connected to an external device by bolts to provide support for the trimming machine. A third telescopic rod 14 is fixedly installed at the upper end of the mounting base 15, and a lifting seat 2 is fixedly installed at the upper end of the third telescopic rod 14. Starting the third telescopic rod 14 can drive the lifting seat 2 to move up and down, and the up and down movement of the lifting seat 2 can drive the conveying roller 1 and the trimming machine as a whole to move up and down, as shown in the appendix Figure 1 As shown, when the lifting seat 2 moves upward, the conveying roller 1 will move upward, which can increase the tension inside the non-woven fabric and make the non-woven fabric taut during transportation. The non-woven fabric tightly attached to the surface of the conveying roller 1 is easier to perform trimming operations; when the lifting seat 2 moves downward, the conveying roller 1 will move downward, and the tension inside the non-woven fabric becomes smaller, which can make the non-woven fabric relax during transportation. Starting the third telescopic rod 14 can drive the conveying roller 1 to move through the lifting seat 2, thereby adjusting the tension state of the non-woven fabric.

[0018] The conveying roller 1 is rotatably arranged inside the lower end of the lifting seat 2. A first lead screw 3 is rotatably installed inside the upper end of the lifting seat 2. The first lead screw 3 is a bidirectional lead screw. The end of the first lead screw 3 is connected to an external motor, and the first lead screw 3 can be driven to rotate by the external motor. A linkage block 4 is sleeved on the outer side of the first lead screw 3. There are a pair of linkage blocks 4. The rotation of the first lead screw 3 can drive the linkage blocks 4 to approach each other or move away from each other simultaneously.

[0019] A first telescopic rod 5 is fixedly installed at the lower end of the linkage block 4. The movement of the linkage block 4 will drive the first telescopic rod 5 to move. A cutter 6 is fixedly installed at the lower end of the first telescopic rod 5. The movement of the first telescopic rod 5 will drive the cutter 6 to move, which can adjust the distance between the cutters 6 and can cut non-woven fabrics of different widths. At the same time, the cutter 6 can be driven to move up and down through the first telescopic rod 5, which can conveniently adjust the height of the cutter 6 and facilitate controlling the cutter 6 to cut the non-woven fabric. In addition, the shape of the cutter shown in the attached drawing is a non-powered cutter, and a circular cutter connected to a motor can also be selected according to specific requirements as long as the cutting work can be completed.

[0020] A flattening mechanism is fixedly installed on the lower surface of the upper end of the lifting seat 2. The flattening mechanism can push and flatten both ends of the non-woven fabric to the two sides. The flattening mechanism includes a second telescopic rod 7. The lengths of the first telescopic rod 5, the second telescopic rod 7, and the third telescopic rod 14 are all vertically arranged. A connecting frame 8 is fixedly installed at the lower end of the second telescopic rod 7. The second telescopic rod 7 can drive the connecting frame 8 to move up and down, and can adjust the height of the connecting frame 8. A second lead screw 9 is rotatably installed inside the connecting frame 8. Both the first lead screw 3 and the second lead screw 9 are bidirectional lead screws. The first lead screw 3 and the second lead screw 9 are parallel to each other and are both horizontally arranged. The end of the second lead screw 9 is connected to an external motor, and the second lead screw 9 can be driven to rotate by the external motor.

[0021] A movable block 10 is sleeved on the outer thread of the second lead screw 9. There are a pair of movable blocks 10. When the second lead screw 9 rotates, it can drive the movable blocks 10 to approach each other or move away from each other simultaneously. The lower end of the movable block 10 is slidably arranged inside the mounting box 11, and the upper end of the mounting box 11 is fixedly connected to the connecting frame 8. A connecting rod 12 is fixedly installed on one side of the movable block 10. When the movable block 10 moves, it drives the connecting rod 12 to move. The end of the connecting rod 12 penetrates and extends to the outside of the mounting box 11 and is fixedly installed with a pushing block 13. When the connecting rod 12 moves, it drives the pushing block 13 to move. The lower surface of the pushing block 13 is arc-shaped and fits the surface of the conveying roller 1. The bottom of the pushing block 13 is made of a rubber structure. The pushing block 13 can directly contact the surface of the non-woven fabric, which can increase the friction with the non-woven fabric. When the connecting rod 12 drives the pushing blocks 13 to move away from each other, the pushing blocks 13 can push both ends of the non-woven fabric to both sides, preventing the non-woven fabric from wrinkling and affecting the edge-cutting effect.

[0022] Working principle: During the working process of this non-woven fabric edge-cutting machine, the non-woven fabric is wound around the conveying roller 1 in the state shown in the attached drawing. If the non-woven fabric wrinkles, start the second telescopic rod 7 to drive the connecting frame 8 to move downward. When the connecting frame 8 moves downward, it can drive the mounting box 11 to move downward. When the mounting box 11 moves downward, it can drive the pushing block 13 to move downward through the connecting rod 12, so that the pushing block 13 abuts against the surface of the non-woven fabric. Then start the second lead screw 9 to drive the movable blocks 10 to move away from each other simultaneously. When the movable blocks 10 move, they will drive the pushing blocks 13 to move away from each other simultaneously through the connecting rods 12. During the moving-away process, the pushing blocks 13 can unfold both sides of the non-woven fabric to both outer sides, preventing the non-woven fabric from wrinkling. Then start the third telescopic rod 14 to drive the lifting seat 2 to move up and down. When the lifting seat 2 moves up and down, it can drive the conveying roller 1 to move up and down, adjusting the tension of the non-woven fabric, making the non-woven fabric slightly taut and fitting on the surface of the conveying roller 1, which is convenient for cutting the frayed edge of the non-woven fabric. Then start the first lead screw 3 to drive the linkage block 4 and the cutting knife 6 to move away from each other or approach each other simultaneously, and adjust the specific position of the cutting knife 6 according to the specific width of the non-woven fabric. Then drive the cutting knife 6 to move downward through the first telescopic rod 5, and cut the frayed edge of the non-woven fabric with the cutting knife 6. As the conveying roller 1 rotates, it can drive the non-woven fabric to move, and continuously cut the non-woven fabric with the cutting knife 6 during the movement of the non-woven fabric.

[0023] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
