Abstract
Description
Technical Field
[0001] This utility model relates to the field of slitting equipment technology, and in particular to a high-speed slitting equipment for anti-fog film. Background Technology
[0002] Anti-fog film, also known as drip-free film, is a film made by adding anti-fog agent to the formulation of polyvinyl chloride or polyethylene agricultural film. Depending on the specific requirements, anti-fog film is cut using a cutting device.
[0003] Existing traditional slitting devices require manual movement of the raw material film after slitting, and it needs to be fed back under the cutter for further cutting. This not only results in poor operational continuity and low slitting efficiency, but also requires workers to constantly operate near the cutter, which is highly dangerous. Utility Model Content

[0009] As a further embodiment of this utility model, the bottom side of the connecting block is provided with a toothed groove, the toothed groove on the connecting block meshes with the gear, and empty slots are provided on both sides of the toothed groove, the empty slots have no teeth and cannot drive the gear to rotate.
[0010] As a further embodiment of this utility model, a connecting pipe is fixedly connected to the left end of the second sleeve, and the other end of the connecting pipe is fixedly connected to the top end of the first sleeve.
[0011] As a further embodiment of this utility model, a limiting groove is provided on the inner wall of the slitting frame, and the two ends of the cutter can be movably engaged in the limiting groove.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] In this invention, the toothed groove on the connecting block drives the gear to rotate counterclockwise, which in turn drives the traction roller to rotate counterclockwise. The traction roller, in conjunction with the movable roller, pushes the anti-fog film to the left by a fixed distance on the cutting table.

When the second piston rod moves to the left, it squeezes the hydraulic oil in the second sleeve. The squeezed hydraulic oil flows into the first sleeve through the connecting pipe. When the hydraulic oil flows into the first sleeve, it pushes the first piston rod to move down. The first piston rod drives the cutter to move down and cut the anti-fog film below, thus achieving automatic and continuous cutting of the anti-fog film without the need for workers to operate near the cutter, improving safety.

[0022] Reference Figure 1 - Figure 4A high-speed anti-fog film slitting device includes a slitting table 1, a traction roller 2 movably mounted on the slitting table 1, a movable roller 4 positioned directly above the traction roller 2, a fixing frame 3 fixedly mounted on the top of the slitting table 1 corresponding to both ends of the movable roller 4, a controller 5 fixedly mounted on the right side wall of the slitting table 1, a slitting frame 6 fixedly mounted on the top left end of the slitting table 1, a first sleeve 9 fixedly mounted at the top center of the slitting frame 6, a first piston rod 10 movably mounted on the bottom end of the first sleeve 9, a cutter 7 fixedly mounted on the bottom end of the first piston rod 10, a one-way bearing 21 fixedly mounted through the left end of the traction roller 2 at the top of the slitting table 1, and a gear 1 fixedly mounted on the outer ring of the one-way bearing 21. 2. A connecting block 13 is provided above the gear 12, and a telescopic cylinder 11 is provided on the right side of the connecting block 13. The telescopic cylinder 11 is fixedly installed on the side wall of the slitting table 1. The telescopic end of the telescopic cylinder 11 is fixedly connected to the right side of the connecting block 13. The telescopic cylinder 11 is started by the controller 5. The telescopic end of the telescopic cylinder 11 can drive the connecting block 13 to move left and right. When the connecting block 13 moves to the left, the gear 12 can be driven to rotate counterclockwise because the tooth groove 14 meshes with the gear 12. At this time, the inner and outer rings of the one-way bearing 21 will be locked, and the gear 12 will drive the traction roller 2 to rotate counterclockwise. The traction roller 2 and the movable roller 4 cooperate to push the anti-fog film to move a fixed distance to the left on the slitting table 1.
[0023] In this embodiment, a second piston rod 15 is fixedly installed on the left side of the connecting block 13, and a second sleeve 16 is provided on the outside of the second piston rod 15. The second sleeve 16 is fixedly installed on the side wall of the cutting table 1. Hydraulic oil 20 is installed between the left side of the second piston rod 15 and the inside of the second sleeve 16. When the connecting block 13 moves left and right, it will also push the second piston rod 15 to move left and right. When the second piston rod 15 moves to the left, it can squeeze the hydraulic oil 20 in the second sleeve 16. The squeezed hydraulic oil 20 can flow into the first sleeve 9 through the connecting pipe 17. When the hydraulic oil 20 flows into the first sleeve 9, it will push the first piston rod 10 to move down. The first piston rod 10 can drive the cutter 7 to move down to cut the anti-fog film below. After the cutting is completed, the second piston rod 15 will move to the right. Since the volume of hydraulic oil 20 is fixed, when the second piston rod 15 moves to the left, it will suck the hydraulic oil 20 back into the second sleeve 16. At this time, the first piston rod 10 will drive the cutter 7 to move up.
[0024] In this embodiment, movable blocks 18 are provided at both ends of the movable roller 4. The movable blocks 18 are movably mounted on the fixed frame 3. The two ends of the movable roller 4 are movably mounted on the movable blocks 18. A spring 19 is fixedly installed between the top of the movable block 18 and the fixed frame 3. The spring 19 can apply a downward force to the movable block 18, and the movable block 18 can drive the movable roller 4 to press down. The anti-fog film can be clamped by the cooperation of the traction roller 2 and the movable roller 4, and then the anti-fog film passes under the cutter 7.
[0025] In this embodiment, a toothed groove 14 is provided on the bottom side of the connecting block 13. The toothed groove 14 on the connecting block 13 meshes with the gear 12, and the connecting block 13 can drive the gear 12 to rotate. Empty slots are provided on both sides of the toothed groove 14. There are no teeth in the empty slots, so the gear 12 cannot be driven to rotate. Since the film feeding and the cutter work synchronously, by providing empty slots on both sides of the toothed groove 14, it can be ensured that the gear 12 will not drive the traction roller 2 to pull the film to move when cutting the film, so that the film will be offset during cutting, resulting in cutting failure.
[0026] In this embodiment, a connecting pipe 17 is fixedly connected to the left end of the second sleeve 16, and the other end of the connecting pipe 17 is fixedly connected to the top end of the first sleeve 9. Hydraulic oil 20 can flow between the second sleeve 16 and the first sleeve 9 through the connecting pipe 17.
[0027] In this embodiment, a limiting groove 8 is provided on the inner wall of the slitting frame 6, and the two ends of the cutter 7 can be movably engaged in the limiting groove 8.
[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When in use, the anti-fog film to be cut passes between the traction roller 2 and the movable roller 4. The spring 19 can apply a downward force to the movable block 18, and the movable block 18 can drive the movable roller 4 to press down. When the film is between the traction roller 2 and the movable roller 4, the movable roller 4 can press the anti-fog film onto the traction roller 2 and clamp it, which facilitates the subsequent traction operation of the film. Then the anti-fog film passes under the cutter 7.
[0029] During slitting, the telescopic cylinder 11 is activated by the controller 5. The telescopic end of the telescopic cylinder 11 can drive the connecting block 13 to move left and right. When the connecting block 13 moves to the left, the tooth groove 14 meshes with the gear 12, thus driving the gear 12 to rotate counterclockwise. At this time, the inner and outer rings of the one-way bearing 21 will be locked, and the gear 12 will drive the traction roller 2 to rotate counterclockwise. The traction roller 2 and the movable roller 4 cooperate to push the anti-fog film to move a fixed distance to the left on the slitting table 1. When the connecting block 13 moves to the right, the tooth groove 14 drives the gear 12 to rotate clockwise, and the one-way bearing 21 cannot drive the traction roller 2 to rotate.
[0030] When the connecting block 13 moves left and right, it also pushes the second piston rod 15 to move left and right. When the second piston rod 15 moves to the left, it can squeeze the hydraulic oil 20 in the second sleeve 16. The squeezed hydraulic oil 20 can flow into the first sleeve 9 through the connecting pipe 17. When the hydraulic oil 20 flows into the first sleeve 9, it will push the first piston rod 10 to move down. The first piston rod 10 can drive the cutter 7 to move down to cut the anti-fog film below, thereby achieving automatic and continuous cutting of the anti-fog film without the need for workers to operate near the cutter 7, which improves safety. By setting empty slots on both sides of the tooth groove 14, it can be ensured that the gear 12 is separated from the tooth groove 14 when cutting the film, and will not drive the traction roller 2 to pull the film to move, causing the film to shift position during cutting and resulting in cutting failure.
[0031] After the cutting is completed, the second piston rod 15 will move to the right. Since the volume of hydraulic oil 20 is fixed, when the second piston rod 15 moves to the left, it will draw the hydraulic oil 20 back into the second sleeve 16. At this time, the first piston rod 10 will drive the cutter 7 to move up to prepare for the next cutting.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of this utility model as claimed.
