Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution for a cutting device for insulating cable processing, including: device table 1, fixed frame 3, connecting column 20, gear 21, fixed rod 22, partition plate 23, connecting frame 24, tooth block 25 and second spring 26. A fixed frame 3 is installed on the device table 1. A connecting column 20 is rotatably connected to the fixed frame 3. One end of the connecting column 20 is installed with a gear 21 inside the fixed frame 3. A fixed rod 22 is installed at the bottom inside the fixed frame 3. A partition plate 23 is installed on the fixed rod 22, and a second spring 26 is sleeved on the fixed rod 22. A connecting frame 24 is slidably connected to the fixed rod 22. A through groove adapted to the partition plate 23 is provided through the bottom inside the connecting frame 24. A baffle 27 is installed at the top of the fixed rod 22. Tooth blocks 25 are vertically arranged in an array on one side of the connecting frame 24. The insulating cable is clamped between the cutting knife 15 and the pressing plate 19. By rotating the connecting column 20 to drive the connecting plate 4, the pressing plate 19 and the cutting knife 15 are driven to rotate. The cutting knife 15 cuts the insulating cable sheath. At the same time, the gear 21 on the connecting column 20 meshes with the tooth block 25, driving the connecting frame 24 to slide downward on the fixed rod 22. The connecting frame 24 presses the second spring 26. Release the connecting column 20. The elastic force of the second spring 26 drives the connecting frame 24 to move upward to reset. The tooth block 25 drives the gear 21 to reverse, driving the cutting knife 15 and the pressing plate 19 to reset, facilitating the next use.

[0022] Such asFigure 1 and Figure 4 As shown, a sliding hole adapted to the fixed rod 22 is provided at the top end of the connecting frame 24. The baffle 27 is located at the top end of the connecting frame 24. The top end of the second spring 26 abuts against the inner wall top end of the connecting frame 24, and the bottom of the second spring 26 abuts against the top end of the partition plate 23. The tooth block 25 meshes with the gear 21. The other end of the connecting column 20 extends to the outside of the fixed frame 3 and is installed with a connecting plate 4. The connecting plate 4 is symmetrically installed with connecting rods 5. One ends of the two groups of connecting rods 5 are both installed with fixing plates 6. Opposite ends of the two groups of fixing plates 6 are both installed with strip plates 7. Support legs 2 are installed at the four corners of the bottom of the device table 1. The top end of the support leg 2 is provided with a collection box 8. A through hole is provided on the device table 1. The collection box 8 is located below the through hole. The cut outer layer of the insulation cable falls through the through hole and is stored in the collection box 8, which is convenient for cleaning.

[0023] As Figure 2 and Figure 3 shown, a group of strip plates 7 are symmetrically installed with screws 9. One ends of the two screws 9 away from the group of strip plates 7 are installed with a retaining piece 10, and a rotating block 11 is threadedly connected to the screw 9. The rotating block 11 rotates and moves on the screw 9 to adjust the movable distance of the connecting piece 12 on the screw 9, and at the same time plays a limiting role. According to the thickness of the outer layer of the insulation cable, the rotating block 11 is rotated and adjusted on the screw 9 so that when the cutting knife 15 contacts the outer layer of the insulation cable through the spring, the inner core will not be directly cut. The two groups of screws 9 are both sleeved with a first spring 14, and the connecting piece 12 is slidably connected to the screw 9. Opposite ends of the two connecting pieces 12 are installed with a fixing piece 13, and a cutting knife 15 is installed on the fixing piece 13. The other group of strip plates 7 is installed with an arc plate 16. Installation grooves are symmetrically arranged inside the arc plate 16. The two groups of installation grooves are both installed with a third spring 17, and a connecting rod 18 is slidably connected in the installation groove. One ends of the two groups of connecting rods 18 are installed with a pressing plate 19. The arc plate 16 is symmetrically provided with a chute adapted to the pressing plate 19. The insulation cable is placed between the pressing plate 19 and the cutting knife 15. The connecting column 20 is rotated to drive the cutting knife 15 to rotate to cut the outer layer of the insulation cable. After the cutting knife 15 cuts the outer layer of the insulation cable, the pressing plate 19 is inserted into the gap after cutting by the cutting knife 15 through the elastic force of the third spring 17, which is convenient for separating the cut outer layer from the insulation cable.

[0024] The working principle of the present utility model is as follows: Rotate the rotating block 11, adjust the movable distance of the connecting piece 12 on the screw 9 according to the thickness of the outer skin of the insulating cable to be cut, pull the fixing piece 13, the connecting piece 12 moves on the screw 9 and compresses the first spring 14. Place the insulating cable between the cutting knife 15 and the abutting plate 19. The abutting plate 19 abuts against the outer skin of the insulating cable by the elastic force of the third spring 17. Release the fixing piece 13, and the cutting knife 15 cuts the outer skin of the insulating cable by the elastic force of the first spring 14. Rotate the connecting column 20 to drive the cutting knife 15 and the abutting plate 19 to rotate. When the cutting knife 15 rotates, it cuts the outer skin of the insulating cable. At the same time, the abutting plate 19 is inserted into the gap cut by the cutting knife 15 by the elastic force of the third spring 17. When the connecting column 20 rotates, the gear 21 rotates together. When the gear 21 rotates, it drives the connecting frame 24 to slide downward on the fixed rod 22 through the tooth block 25. The connecting frame 24 compresses the second spring 26. Release the connecting column 20, and the connecting frame 24 slides upward and resets on the fixed rod 22 by the elastic force of the second spring 26, and at the same time drives the abutting plate 19 and the cutting knife 15 to rotate and reset, cutting the outer skin of the insulating cable again. Pull the insulating cable, and the cut insulating layer skin is separated from the inner core of the insulating cable by the blocking of the abutting plate 19 and the cutting knife 15, and falls through the through hole on the device table 1 into the collection box 8 for storage.

[0025] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
