Specific embodiments

[0025] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 to 7, a cutting device for heat-shrinkable insulation sheaths, comprising a guiding frame 1. A fixed-length component 7 is provided at the bottom of the guiding frame 1. A blade 2 is slidably connected inside the guiding frame 1. The heat-shrinkable insulation sheath is passed through the guiding frame 1. The guiding frame 1 can guide the heat-shrinkable insulation sheath, preventing it from tilting and improving the cutting quality. A pressing plate 3 is provided at the bottom of one side of the blade 2. A pressure transmission component 14 for pressing the top of the blade 2 is provided at the top of the blade 2. A machine case 11 is fixedly provided at the top of the guiding frame 1. A support shaft 16 is rotatably connected inside the machine case 11. Cam 17s for driving the pressure transmission component 14 to descend are fixedly provided on both sides of the support shaft 16. A motor 13 is fixedly installed on one side of the machine case 11. The output shaft of the motor 13 is connected to one end of the support shaft 16. By driving the support shaft 16 with the motor 13, the cam 17 is driven to rotate. The cam 17 can drive the pressure transmission component 14 to press the blade 2, enabling the blade 2 to cut the heat-shrinkable insulation sheath;

[0027] In this embodiment, preferably, the fixed-length component 7 includes a curved baffle 701. Slide bars 702 are fixedly provided on both sides of the curved baffle 701. A scale 703 is provided on the surface of the slide bar 702. A sleeve 704 is slidably connected to the surface of the slide bar 702. The sleeve 704 is fixedly connected to the guiding frame 1. A threaded hole 705 is opened at the top of the sleeve 704. A locking screw 706 is threadedly connected inside the threaded hole 705. One end of the heat-shrinkable insulation sheath can be limited by the curved baffle 701, enabling fixed-length cutting of the heat-shrinkable insulation sheath. By sliding the slide bar 702, the distance between the curved baffle 701 and the blade 2 can be adjusted, and the cutting length of the heat-shrinkable insulation sheath can be adjusted. By tightening the locking screw 706, the slide bar 702 can be limited after adjusting the heat-shrinkable insulation sheath;

[0028] In this embodiment, preferably, the pressure transmission component 14 includes a pressure bar 1401. A cylinder 1402 is rotatably connected to the middle of the top end of the pressure bar 1401. The cam 17 is slidably connected to the cylinder 1402. Smooth round rods 1403 are fixedly provided at the four corners of the bottom end of the pressure bar 1401. A return spring 1404 is sleeved on the surface of the smooth round rods 1403. The middle of the bottom end of the pressure bar 1401 is fixedly connected to the top end of the blade 2. When the convex point of the cam 17 rotates to the pressure bar 1401, it can exert pressure on the pressure bar 1401, causing the pressure bar 1401 to descend. The cylinder 1402 can reduce the friction when the cam 17 rotates. When the pressure bar 1401 descends, it can compress the return spring 1404 and drive the blade 2 to descend to cut the heat-shrinkable insulation sheath. After the cutting is completed, the convex point of the cam 17 leaves the pressure bar 1401, and the return spring 1404 can push the pressure bar 1401 and the blade 2 to reset. A rod groove 6 is opened at the top end of the guide frame 1, and the smooth round rod 1403 is slidably connected to the rod groove 6. The rod groove 6 can guide the smooth round rod 1403. The return spring 1404 is located between the pressure bar 1401 and the guide frame 1. A maintenance opening is provided on the surface of the chassis 11, and a cover plate 12 is snap-connected to one side of the maintenance opening. The pressure bar 1401 is located inside the chassis 11. By opening the cover plate 12, the inside of the chassis 11 can be maintained;

[0029] In this embodiment, preferably, a base 8 is fixedly provided at the bottom end of the guide frame 1. Two reinforcing rods 9 are fixedly provided inside the base 8. Positioning strips 10 are fixedly provided on both sides of the bottom end of the base 8. Positioning holes are provided on the surface of the positioning strips 10. The base 8 can be fixed through the positioning holes and the positioning strips 10. The base 8 can support the guide frame 1. A material discharging opening 15 is provided on one side of the bottom end of the guide frame 1. The pressing plate 3 and the material discharging opening 15 are located in the same vertical plane. A knife groove 4 is provided inside the guide frame 1, and the blade 2 is slidably connected to the knife groove 4. A slideway 5 communicating with the knife groove 4 is opened at the top end of the guide frame 1, and the top of the blade 2 is slidably connected to the slideway 5. The knife groove 4 and the slideway 5 can guide the blade 2 and ensure the cutting activity of the blade 2 on the heat-shrinkable insulation sheath.

[0030] During use, first slide the sliding rod 702 of the fixed-length component 7 to adjust the distance between the curved surface baffle 701 and the blade 2 to adjust the cutting length of the heat-shrinkable insulation sheath. Then tighten the locking screw 706 to limit the sliding rod 702 after adjusting the heat-shrinkable insulation sheath. Then pass the heat-shrinkable insulation sheath through the guide frame 1. The guide frame 1 can guide the heat-shrinkable insulation sheath and prevent it from tilting. The curved surface baffle 701 can limit one end of the heat-shrinkable insulation sheath. Finally, drive the support shaft 16 through the motor 13 to drive the cam 17 to rotate;

[0031] When the bump of the cam 17 rotates to the pressure bar 1401, it can exert pressure on the pressure bar 1401, causing the pressure bar 1401 to descend. The cylinder 1402 can reduce the friction when the cam 17 rotates. When the pressure bar 1401 descends, it can compress the return spring 1404 and drive the blade 2 to descend to cut the heat-shrinkable insulation sheath. When the bump of the cam 17 leaves the pressure bar 1401, the return spring 1404 can push the pressure bar 1401 and the blade 2 to reset. When the cam 17 rotates one week, the blade 2 can complete a reciprocating motion, thus continuously cutting the heat-shrinkable insulation sheath;

[0032] During continuous cutting, the blade 2 can drive the pressure plate 3 to descend to exert pressure on the cut heat-shrinkable insulation sheath, facilitating its feeding through the blanking port 15. When the heat-shrinkable insulation sheath is stuck between the guide frame 1 and the curved surface baffle 701, the heat-shrinkable insulation sheath is pushed for feeding, and the cut heat-shrinkable insulation sheath is pushed to move. One end of the heat-shrinkable insulation sheath can fall along the inner wall of the curved surface baffle 701.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
