[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-4The utility model provides a technical solution: a cutting device for heat shrinkable insulating sheath, comprising a base 1, a support frame 2 is arranged on one side of the upper end of the base 1, a third motor 15 is arranged below the support frame 2, and a cutting blade 16 is installed at the output end of the third motor 15;
[0026] It also includes a first transmission chamber 4, which is opened at the upper end of the support frame 2, and a single-threaded transmission rod 5 is rotatably arranged inside the first transmission chamber 4, and an L-shaped block 7 is connected to the external thread of the single-threaded transmission rod 5, and one end of the L-shaped block 7 extends to the outside of the first transmission chamber 4, and a first electric telescopic rod 14 is installed at one end of the L-shaped block 7 and the outside of the first transmission chamber 4, and the output end of the first electric telescopic rod 14 is connected to the third motor 15, and a scale 3 is arranged on the upper side of the front end of the support frame 2;
[0027] It also includes a second transmission chamber 9, which is opened on the front and rear sides of the base 1. A double-threaded transmission rod 10 is rotatably arranged inside the second transmission chamber 9. Both sides of the outside of the double-threaded transmission rod 10 are threadedly connected with a moving block 12, and one end of the moving block 12 extends to the outside of the second transmission chamber 9.
[0028] When in use, after fixing the heat shrinkable insulating sheath, start the first motor 6, so that the single-threaded transmission rod 5 drives the L-shaped block 7 to rotate synchronously, and under the axial limit of the first guide rod 8, the rotation of the L-shaped block 7 is converted into horizontal linear movement. The movement of the L-shaped block 7 will drive the L-shaped pointer 19 to move in front of the scale 3, and can drive the cutting blade 16 to move synchronously. The user can judge the moving distance of the cutting blade 16 according to the position of the L-shaped pointer 19 on the scale 3, and can adjust it according to the required length of the heat shrinkable insulating sheath.
[0029] See also Figure 2 A first motor 6 is disposed on one side of the first transmission chamber 4, and an output end of the first motor 6 is connected to a single-threaded transmission rod 5 through a coupling, and the first motor 6 provides power for the cutting of the cutting blade 16;
[0030] See also Figure 2 A second motor 11 is disposed on one side of the second transmission cavity 9, and an output end of the second motor 11 is connected to a double-threaded transmission rod 10 through a coupling, and the second motor 11 provides power for the movement of the two moving blocks 12;
[0031] See also Figure 1 and Figure 4 An L-shaped pointer 19 is welded to the front end of the L-shaped block 7 located outside the first transmission chamber 4, and one end of the L-shaped pointer 19 extends to the front of the scale 3. The setting of the L-shaped pointer 19 facilitates the user to intuitively judge the moving distance of the cutting blade 16;
[0032] See also Figure 1 , Figure 2 and Figure 3 A second electric telescopic rod 17 is arranged at the upper end of the moving block 12, and an arc-shaped clamping block 18 is installed at the output end of the second electric telescopic rod 17. The cooperation between the second electric telescopic rod 17 and the arc-shaped clamping block 18 can realize the overhead fixation of the heat shrinkable insulation sheath to avoid the movement of the heat shrinkable insulation sheath during cutting;
[0033] See also Figure 2 and Figure 3 The first guide rods 8 are welded on the front and rear sides of the first transmission chamber 4. The first guide rods 8 all penetrate the L-shaped block 7, and the first guide rods 8 all slide with the L-shaped block 7. The first guide rods 8 can convert the rotation of the L-shaped block 7 into horizontal linear movement, so that the L-shaped block 7 can drive the cutting blade 16 and the L-shaped pointer 19 to move synchronously;
[0034] See also Figure 2 and Figure 3 A second guide rod 13 is welded on the lower side of the second transmission chamber 9, and the second guide rod 13 passes through the moving block 12, and the second guide rod 13 slides with the moving block 12. The setting of the second guide rod 13 can play an axial limiting role in the rotation of the moving block 12, so that the rotation of the moving block 12 is converted into a horizontal linear movement, thereby driving the arc clamping block 18 to change the clamping position.
[0035] Working principle: When in use, one end of the heat-shrinkable insulating sheath is brought into contact with one side of the support frame 2 so that the heat-shrinkable insulating sheath is located between the arc-shaped clamping blocks 18, and the second electric telescopic rod 17 is started. Its output end will drive the arc-shaped clamping block 18 to clamp and fix the middle heat-shrinkable insulating sheath to avoid shaking during cutting. The user can start the second motor 11, and the output end of the second motor 11 will drive the double-threaded transmission rod 10 to rotate synchronously through the coupling. The double-threaded transmission rod 10 will drive the two moving blocks 12 to rotate synchronously. Under the axial limiting action of the second guide rod 13, the rotation of the two moving blocks 12 will be converted into opposite or opposite horizontal linear movement, so that when the two moving blocks 12 move, they can drive the second electric telescopic rod 17 to make the arc-shaped clamping block 18 move synchronously. The user can change the clamping position of the arc-shaped clamping block 18 to avoid affecting subsequent cutting. After fixing the heat shrinkable insulating sheath, start the first motor 6. The first motor 6 will drive the single-threaded transmission rod 5 to rotate synchronously, and the single-threaded transmission rod 5 will drive the L-shaped block 7 to rotate synchronously. Since the L-shaped block 7 is slidably matched with the two first guide rods 8, the L-shaped block 7 will be axially limited, and the rotation of the L-shaped block 7 will be converted into horizontal linear movement. When the L-shaped block 7 moves, it will drive the cutting blade 16 to move synchronously. At the same time, the movement of the L-shaped block 7 will drive the L-shaped pointer 19 to move in front of the scale 3. The user can judge the distance moved by the cutting blade 16 according to the position of the L-shaped pointer 19 on the scale 3, so as to adjust it according to the required length of the heat shrinkable insulating sheath. After adjusting the distance of the cutting blade 16, start the first electric telescopic rod 14 to move the third motor 15 downward, and then start the third motor 15 to drive the cutting blade 16 to cut.
