Description

Technical Field

[0001] This utility model relates to the field of PVC mesh fabric processing technology, specifically to a cutting device suitable for PVC mesh fabric processing. Background Technology

[0002] PVC mesh fabric is a composite material made of polyvinyl chloride (PVC) coating and a base material (such as cotton, polyester, nylon, etc.). During processing, PVC mesh fabric requires edge trimming. A search revealed patent CN220867842U, which discloses an edge trimming device for mesh fabric production. In use, an external power supply is first connected. The distance between adjacent cutters is adjusted according to the width of the mesh fabric. The operator uses a handwheel to rotate a screw inside a fixed frame, causing the fixed frame and cutters to slide along a guide shaft until the distance between adjacent cutters is adjusted. To meet the cutting requirements of the mesh fabric, the operator inserts the take-up drum into the inside of the sleeve through a notch on one side of the second connecting plate. Then, the locking screw secures the take-up drum and sleeve. Next, the mesh fabric passes between the pressure roller and the placement plate. A spring provides a downward force to the slider, causing the pressure roller to press and limit the mesh fabric, preventing it from jumping upwards during cutting. This facilitates cutting by the cutter and ensures normal operation of the cutter. The mesh fabric can then be removed from the existing unwinding roller and rewound using the existing take-up roller. The roller rewinds the mesh fabric, which moves in the direction of the arrow on the placement plate. Workers can first cut the mesh fabric on both sides using the cutters on both sides, then pass the cut-off scrap through the gap between the fixed frame and the cutters and wrap it around the outside of the winding drum. The second motor then drives the winding drum to rewind the scrap, ensuring that the winding drum can complete the winding of the scrap while the cutters are cutting the edges of the mesh fabric, saving space and facilitating scrap disposal. When the winding drum is finished winding the scrap, the worker removes the locking screws... Remove the inner side of the sleeve, and then remove the winding drum and waste material from one side of the second connecting plate to complete the cutting of the mesh fabric. However, during the edge cutting process, the mesh fabric is easily pulled due to the winding of the waste edge. Since the main purpose of the edge cutting is to ensure the neatness of the mesh fabric, it is easy to cause unevenness in the overall structure of the mesh fabric, thus making the edge cutting meaningless. Therefore, an edge cutting device suitable for PVC mesh fabric processing is designed to facilitate relatively flat edge cutting of PVC mesh fabric and ensure that the overall structure of the PVC mesh fabric does not deform.

The elastic mechanism includes a U-shaped sliding plate that slides vertically with the operating table. The lower guide roller is rotatably connected to the U-shaped sliding plate. The operating table is provided with a limiting slot that matches the U-shaped sliding plate. When the top of the U-shaped sliding plate slides into the limiting slot, the top of the lower guide roller is flush with the top of the operating table. A limiting frame is provided below the U-shaped sliding plate and is fixedly connected to the bottom of the operating table. A compression spring is provided between the limiting frame and the bottom of the U-shaped sliding plate. The two ends of the compression spring are fixedly connected to the limiting frame and the U-shaped sliding plate, respectively.

[0008] Preferably, the trimming mechanism includes a cutting frame that slides vertically on a movable frame, a cutting blade that is rotatably connected to the bottom of the cutting frame via a trimming motor, a cutting drive cylinder that is vertically fixedly mounted on the movable frame, and the bottom output end of the cutting drive cylinder being fixedly connected to the top of the cutting frame.

[0009] Preferably, at least one of the two ends of the seam rollers above the lower guide rollers is provided with a traction motor, the traction motor is fixedly mounted on the same side of the movable frame and the output shaft of the traction motor is fixedly connected to the seam roller.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a cutting device suitable for processing PVC mesh fabric, which has the following advantages:

[0014] This edge-cutting device for PVC mesh fabric processing uses two lower guide rollers and two sets of rollers directly above each lower guide roller. The distance between the two saddle rollers on both sides can be adjusted according to the thickness of the edge to be cut, and the two edge-cutting mechanisms are adjusted to be directly above the cut seams on both sides. This allows all the saddle rollers above to press the PVC mesh fabric tightly onto the two lower guide rollers from above. By moving the two edge-cutting mechanisms downwards to perform the edge-cutting operation on the PVC mesh fabric, the mesh fabric can be pulled to one side, continuously cutting the PVC mesh fabric. During edge cutting, the flatness of the cut edge is ensured, and the PVC mesh fabric is prevented from deforming. This edge-cutting device for PVC mesh fabric processing facilitates relatively flat edge cutting of PVC mesh fabric, ensuring that the overall structure of the PVC mesh fabric remains undeformed.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figure 1-5 An edge-cutting device suitable for processing PVC mesh fabric includes an operating table 1. Two sets of lower guide rollers 2 are arranged in parallel on the operating table 1. Each set of lower guide rollers 2 has two end seats with seam rollers 8 positioned directly above it. A movable frame 7 is positioned above the seam rollers 8 located on the same side and above the two sets of lower guide rollers 2. The seam rollers 8 are rotatably connected to the bottom of the movable frame 7. An edge-cutting mechanism that can be raised and lowered on the movable frame 7 is positioned between the two seam rollers 8 directly above the two lower guide rollers 2 on the same side. The two movable frames 7 can be raised and lowered as a whole and the spacing between them can be adjusted.

[0024] Specifically, elastic mechanisms are provided on both sides of the lower guide roller 2 and the operating table 1. The elastic mechanisms include a U-shaped sliding plate 3 that slides vertically with the operating table 1. The lower guide roller 2 and the U-shaped sliding plate 3 are rotatably connected. The operating table 1 has a limiting slot 4 that matches the U-shaped sliding plate 3. When the top of the U-shaped sliding plate 3 slides into the limiting slot 4, the top of the lower guide roller 2 is flush with the top of the operating table 1. A limiting frame 5 is fixedly connected to the bottom of the operating table 1 below the U-shaped sliding plate 3. A compression spring 6 is provided between the limiting frame 5 and the bottom of the U-shaped sliding plate 3. The two ends of the compression spring 6 are fixedly connected to the limiting frame 5 and the U-shaped sliding plate 3, respectively. By setting up the elastic mechanism, it is convenient to make the PVC mesh fabric pass smoothly across the operating table 1 when pressing it. When the upper seam roller 8 presses the lower guide roller 2, the compression spring 6 can be further pressed until the top of the U-shaped sliding plate 3 is inserted into the limiting slot 4, so that the top of the lower guide roller 2 is flush with the top of the operating table 1.

[0025] Specifically, the edge-cutting mechanism includes a cutting frame 13 that slides vertically on a movable frame 7. The bottom of the cutting frame 13 is rotatably connected to a cutting blade 9 via an edge-cutting motor 11. A cutting drive cylinder 12 is vertically fixedly mounted on the movable frame 7. The bottom output end of the cutting drive cylinder 12 is fixedly connected to the top of the cutting frame 13. When the edge-cutting motor 11 is started, it is convenient to drive the cutting blade 9 to rotate. Then, the cutting drive cylinder 12 moves the cutting frame 13, the cutting blade 9, and the edge-cutting motor 11 downward as a whole, so that the rotating cutting blade 9 can perform edge-cutting operations on the PVC mesh fabric.

[0026] Specifically, at least one of the two saddle rollers 8 above the lower guide roller 2 is equipped with a traction motor 10. The traction motor 10 is fixedly installed on the movable frame 7 on the same side and the output shaft of the traction motor 10 is fixedly connected to the saddle roller 8. By setting the traction motor 10, it is convenient to drive the saddle rollers 8 on both sides to rotate, so as to cooperate with the lower guide roller 2 to perform edge cutting operation on the PVC mesh fabric.

[0027] Specifically, it also includes a spacing adjustment mechanism for driving the two movable frames 7 to adjust the spacing. The spacing adjustment mechanism includes a screw 16 and a guide rod 17 arranged in parallel. The screw 16 has two threaded blocks 18 that are fixedly connected to the two movable frames 7 respectively. The guide rod 17 has two guide blocks 19 that are fixedly connected to the two movable frames 7 respectively. By driving the screw 16 to rotate clockwise or counterclockwise, and under the guidance of the guide rod 17 and the two threaded blocks 18, the two threaded blocks 18 and the two movable frames 7 are driven to move towards the middle or to both sides.

[0028] Specifically, it also includes a lifting mechanism that drives the screw 16 and guide rod 17 to move up and down as a whole. The lifting mechanism includes a lifting drive cylinder 14 fixedly installed at the bottom of the operating table 1. The bottom output shaft of the lifting drive cylinder 14 is fixedly installed with a lifting slide 15 that slides and guides the operating table 1. The screw 16 and guide rod 17 are rotatably connected to the lifting slide 15. An adjustable motor that drives the screw 16 to rotate is fixedly installed on the lifting slide 15. Through the lifting drive cylinder 14, the lifting slide 15, screw 16, guide rod 17 and two moving frames 7 can be easily driven to move up and down as a whole, thereby driving the two seam rollers 8 and the edge cutting mechanism to move up and down as a whole.
