Description

Technical Field

[0001] This utility model relates to the field of PVC sheath processing technology, specifically a PVC sheath slitting machine. Background Technology

[0002] PVC sheath is an outer sheath material made of polyvinyl chloride, also known as PVC soft sheath. When used, it can protect cables and other items.

[0003] After PVC sheaths are extruded and molded, workers need to cut them according to subsequent use requirements. Currently, some PVC sheath slitting machines cut PVC sheaths with blades. However, when cutting shorter lengths of softer PVC sheaths, the pressure of the blades on the PVC sheaths can easily cause one end of the PVC sheath to curl up, thus affecting the flatness of the cut surface. In addition, when the cut length of such PVC sheaths is longer, one end is in a drooping state, and the tension state of the upper and lower parts of the surface is different. When the blades cut, it is still easy to cause uneven cut surfaces, which affects the aesthetics of the PVC sheaths after slitting and their subsequent use. Utility Model Content

[0004] The purpose of this invention is to provide a PVC sheath slitting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PVC sheath slitting machine, comprising a worktable and a support fixedly connected to the top of the worktable, and further comprising: A cutting mechanism is installed on the top of the bracket, and pull ropes are threaded through both sides of the bracket surface; The brackets are fixedly connected to both sides of the support surface. A movable frame is slidably connected inside the bracket. The pull rope is fixedly connected to the movable frame. A spring is fixedly connected between the movable frame and the inner wall of the bracket. The limiting mechanism installed inside the moving frame and the extension shaft that moves through the moving frame are fixedly connected to both sides of the support surface, and the inner surface of the reinforcing plate is equipped with a guide mechanism.

[0006] Preferably, the cutting mechanism includes an electric push rod bolted to the top of the bracket, the piston rod of the electric push rod sliding through the bracket and fixedly connected to a lifting plate, a blade fixedly connected to the bottom of the lifting plate, and one end of the pull rope fixedly connected to the surface of the lifting plate.

[0007] Preferably, a guide roller is mounted on the surface of the bracket, the surface of the guide roller is in contact with the surface of the pull rope, and a partition is welded to the surface of the bracket, through which the pull rope passes.

[0008] Preferably, the top and bottom of the movable frame are fixedly connected to sliders, and the top and bottom of the shaped frame are provided with sliding grooves, and the surface of the slider is slidably connected to the inner wall of the sliding groove.

[0009] Preferably, the limiting mechanism includes a rectangular block slidably connected to the upper and lower parts of the inside of the movable frame and two clamping rollers for clamping the PVC sheath. A spring is fixedly connected between the rectangular block and the inner wall of the movable frame. A light rod is fixedly inserted through both sides of the inner wall of the movable frame. The rectangular block is slidably sleeved on the surface of the light rod. One end of the clamping roller is rotatably connected to the surface of the rectangular block. The extension shaft is rotatably connected to the surface of the rectangular block.

[0010] Preferably, the guiding mechanism includes a guide block fixedly connected to the inner surface of the reinforcing plate, and arc-shaped plates are fixedly connected to both the upper and lower surfaces of the inner surface of the reinforcing plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention can drive the limiting mechanism and the extension shaft to move when the blade is raised and lowered. During this process, the guide mechanism controls the distance between two adjacent extension shafts, thereby adjusting the position of the two clamping rollers. This allows the clamping rollers to limit one end of the PVC sheath during the cutting process and release the clamping rollers from the PVC sheath after cutting. This solves the problem that some current PVC sheath slitting machines are inconvenient to support and limit the end of the PVC sheath that needs to be cut, and that sagging or tilting of one end of the PVC sheath can easily affect the flatness of the cut surface.

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.

[0015] Please see Figure 1-6 As shown, a PVC sheath slitting machine includes a worktable 1 and a support 2 fixedly connected to the top of the worktable 1. A cutting mechanism 3 is installed on the top of the support 2. The cutting mechanism 3 includes an electric push rod 31 bolted to the top of the support 2. The piston rod of the electric push rod 31 slides through the support 2 and is fixedly connected to a lifting plate 32. A blade 33 is fixedly connected to the bottom of the lifting plate 32. The blade 33 can cut the PVC sheath by moving up and down. Pull ropes 5 pass through both sides of the surface of the support 2. One end of the pull rope 5 is attached to the surface of the lifting plate 32. The support 2 is fixedly connected to a guide roller 6, which is in contact with the surface of the pull rope 5. When the pull rope 5 moves, the guide roller 6 can support and guide the pull rope 5 and increase the smoothness of the pull rope 5 during movement. The support 2 is welded with a partition 7, through which the pull rope 5 passes. Both sides of the support 2 are fixedly connected to a U-shaped frame 8. The U-shaped frame 8 is slidably connected to a movable frame 9 inside. The other end of the pull rope 5 is fixedly connected to the movable frame 9. A spring 10 is fixedly connected between the movable frame 9 and the inner wall of the U-shaped frame 8.

[0016] Under the elastic force of spring 10, the movable frame 9 can move away from the support 2. Slider 11 is fixedly connected to the top and bottom of the movable frame 9. Slide grooves are provided at the top and bottom of the U-shaped frame 8. The surface of the slider 11 is slidably connected to the inner wall of the slide groove. The cooperation between the slider 11 and the slide groove guides the movement of the movable frame 9. A limiting mechanism 12 is installed inside the movable frame 9. The limiting mechanism 12 includes rectangular blocks 122 slidably connected to the upper and lower parts of the movable frame 9, and two clamping rollers 124 for clamping the PVC sheath. Spring 123 is fixedly connected between the rectangular blocks 122 and the inner wall of the movable frame 9. The elastic force of spring 123 can push adjacent rectangular blocks 122 towards each other. Smooth rods 121 are fixedly inserted through both sides of the inner wall of the movable frame 9. The rectangular blocks 122 are slidably sleeved on the surface of the smooth rods 121. The smooth rods 121 guide and limit the movement of the rectangular blocks 122. One end of the clamping rollers 124 is connected to the rectangular blocks 122... The surface of the support 2 is rotatably connected, and the surface of the rectangular block 122 is rotatably connected to an extension shaft 13 that movably passes through the moving frame 9. Reinforcing plates 14 are fixedly connected to both sides of the surface of the support 2. A guide mechanism 15 is installed on the inner surface of the reinforcing plate 14. The guide mechanism 15 includes a guide block 151 fixedly connected to the inner surface of the reinforcing plate 14. Arc-shaped plates 152 are fixedly connected to the upper and lower sides of the inner surface of the reinforcing plate 14. A baffle 153 is installed at one end of the arc-shaped plate 152 via a torsion spring. The surface of the baffle 153 is in contact with the surface of the guide block 151. The extension shaft 13 is in contact with the surfaces of the guide block 151, the arc-shaped plate 152, and the baffle 153. When the extension shaft 13 moves with the moving frame 9, it can move on the surface of the guide block 151. At this time, the distance between two adjacent extension shafts 13 increases, and the arc-shaped plate 152 rotates under force. Subsequently, under the action of the torsion spring, the baffle 153 rotates in the opposite direction and re-fits the surface of the guide block 151. At this time, the state of the guide mechanism 15 is as follows: Figure 6 As shown, when the extension shaft 13 moves in the opposite direction with the moving frame 9, the extension shaft 13 can move on top of the baffle 153 and the arc plate 152. The distance between the two extension shafts 13 increases again until the arc plate 152 releases the support of the extension shaft 13. The extension shaft 13 moves with the rectangular block 122. The adjacent two extension shafts 13 move towards each other. The surface of the extension shaft 13 contacts the surface of the guide block 151 and moves on the surface of the guide block 151.

[0017] Working principle: The electric push rod 31 is started and drives the lifting plate 32 to rise. The blade 33 is raised accordingly, providing space for the movement of one end of the PVC sheath. The PVC sheath moves below the blade 33. The inner wall of the bracket 2 is fixedly connected to the support plate 4. The support plate 4 can support the bottom of the PVC sheath and limit the height of the blade 33. The blade 33 cooperates with the support plate 4 to cut the PVC sheath. When the lifting plate 32 is raised, the pull rope 5 is forced to move the moving frame 9 to the position of the bracket 2. The spring 10 is stretched. When the blade 33 falls, the blade 33 cuts the PVC sheath. The moving frame 9 moves in the opposite direction under the action of the spring 10. When the moving frame 9 moves towards the position of the bracket 2, the extension shaft 13 moves on top of the arc plate 152 and the baffle 153. At this time, the distance between two adjacent extension shafts 13 increases, and the rectangular block 122 moves accordingly. The distance between the two clamping rollers 124 can then increase. When the contact between the arc plate 152 and the extension shaft 13 is released, under the elastic force of the second spring 123, the clamping rollers 124 on both sides move towards each other and clamp the PVC sheath to restrict the position of the PVC sheath. At this time, the blade 33... When the blade 33 is in the raised state and descends, the moving frame 9 drives the limiting mechanism 12 and the extension shaft 13 to move. The extension shaft 13 moves on the surface of the guide block 151. The guide block 151 pushes the extension shafts 13 on the adjacent sides apart. The clamping roller 124 releases its grip on the PVC sheath. The PVC sheath that has been cut falls off, completing the cutting operation. The surface of the reinforcing plate 14 is fixedly connected to the vertical plate 16. The vertical plate 16 is fixedly connected to the surface of the frame 8. The vertical plate 16 can limit the movement range of the extension shaft 13.
