DETAILED DESCRIPTION

[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1-Figure 7 The illustrated structure for cutting off the insulating sleeve of a transmission line comprises a front shell 1 and a rear shell 2, wherein a ring cutting mechanism is installed at the connection between the front shell 1 and the rear shell 2, and the ring cutting mechanism specifically comprises a cutting groove 23 arranged inside the connection between the front shell 1 and the rear shell 2, wherein a connecting disk 9 is rotatably connected inside the cutting groove 23 close to the side of the front shell 1, and a gear ring 8 is fixedly connected to the end of the connecting disk 9 away from the front shell 1, and a turntable 10 is rotatably connected to the end of the gear ring 8 away from the connecting disk 9, and the gear ring 8 can drive the turntable 10 to rotate, thereby driving the blade 12 to rotate. When cutting the insulating sleeve, the extrusion cutting method is abandoned, and the rotating blade 12 is used to cut the insulating sleeve. When facing an insulating sleeve with a thinner sleeve wall, the insulating sleeve can be effectively prevented from deformation, and the insulating sleeve that has not been cut off can be prevented from being crushed, thereby ensuring the quality of the insulating sleeve after cutting.

[0026] A plurality of rotating columns 15 are installed at one end of the turntable 10 away from the gear ring 8, and a tool holder 11 is fixedly installed on the end faces of the plurality of rotating columns 15, and a blade 12 is fixedly installed inside the tool holder 11. A plurality of limiting grooves 13 are arranged on the inner side of the turntable 10, and a fixed column 14 is arranged inside the plurality of limiting grooves 13. The two end faces of the fixed column 14 are fixedly connected with the gear ring 8 and the tool holder 11. When the gear ring 8 rotates, it will first drive the fixed column 14 to move, and through the action of the rotating column 15, it will drive the tool holder 11 to rotate, so that the blade 12 is close to the surface of the insulating sleeve to be cut. After the tool holder 11 is restricted by the insulating sleeve, the gear ring 8 will drive the turntable 10 to rotate, thereby realizing the ring cutting work, and the tool holder 11 is adjustable and can be used with different types of insulating sleeves.

[0027] A driving mechanism for controlling the circular cutting mechanism is arranged inside the rear shell 2, and the driving mechanism includes a driving motor 6 fixedly mounted on the top of the rear shell 2, and the output end of the driving motor 6 is fixedly connected to a gear 7, and a gear ring 8 is meshed with the gear 7. The driving mechanism can provide conditions for the rotation of the circular cutting mechanism, and no manual cutting is required. After determining the length to be cut, the driving mechanism can be used to cut the insulating sleeve, which saves human resources and reduces workload.

[0028] An installation mechanism is provided inside the tool holder 11, and the installation mechanism includes a installation groove 16 provided inside the tool holder 11, an elastic member 17 is fixedly installed at one closed end inside the installation groove 16, and a pressure plate 18 is fixedly connected to one end of the elastic member 17 away from the closed end of the installation groove 16, and a plurality of limiting columns 19 are fixedly connected to the inner wall of the installation groove 16. After the blade 12 is installed into the tool holder 11, the elastic member 17 will be compressed, and a top force will always be applied to the insertion rod 20, so that the limiting column 19 and the slide groove 21 are more closely matched, so as to prevent the blade 12 from falling off and affecting the work efficiency during the cutting work of the insulating sleeve.

[0029] The connecting end of the blade 12 and the tool holder 11 is fixedly connected with an insertion rod 20, and a plurality of slide grooves 21 are arranged on the surface of the insertion rod 20. The slide groove 21 is in a "J" shape. The limiting column 19 cooperates with the slide groove 21 and limits the slide groove 21. The number of the slide grooves 21 corresponds to the number of the limiting columns 19. The blade 12 can be quickly installed and removed through the installation mechanism, which facilitates the replacement of a damaged blade 12. The installation and removal of the blade 12 require two working processes of squeezing and rotating. Therefore, when the circumcision mechanism is working, the blade 12 cannot fall off easily, which further enhances the stability of the installation of the blade 12.

[0030] The front shell 1 and the rear shell 2 are provided with a connecting flange 3 and are fixed to each other by the connecting flange 3. The front shell 1 and the rear shell 2 connected by the connecting flange 3 can be disassembled. When the internal structure is damaged or cannot work due to other reasons, the front shell 1 and the rear shell 2 can be disassembled to repair the interior. An inlet 4 is provided at the end of the front shell 1 away from the rear shell 2, and an outlet 5 is provided at the end of the rear shell 2 away from the front shell 1.

[0031] The gear ring 8, the connecting disk 9 and the rotating disk 10 are all in a ring shape. The inner walls of the gear ring 8, the connecting disk 9 and the rotating disk 10 are the same size as the inlet 4 and cooperate with it to form a feed pipe 22. The feed pipe 22 is a pipe that needs to pass through during the cutting process of the insulating sleeve. It enters from the inlet 4 and falls from the outlet 5 after cutting.

[0032] An auxiliary mechanism is provided inside the front shell 1 at the entrance 4, and the auxiliary mechanism includes four spring frames 24 respectively fixedly connected to the top end and the bottom end of the inner wall of the front shell 1. The spring frames 24 are used by internal springs to make the auxiliary mechanism retractable, so that it can adapt to the use of insulating sleeves of different sizes. Every two spring frames 24 form a group, and an auxiliary roller 25 is rotatably connected between the two spring frames 24 of each group. The auxiliary roller 25 can facilitate the movement of the insulating sleeve and save the physical strength of the staff.

[0033] A fixing mechanism is provided inside the front shell 1 and the rear shell 2, and the fixing mechanism includes a cylinder 26 fixedly installed inside the front shell 1 and the rear shell 2. The output end of the cylinder 26 is fixedly connected to a clamping plate 27, and the clamping plate 27 is located inside the front shell 1 and the rear shell 2. The clamping plate 27 is driven by the cylinder 26 to fix the insulating sleeve to be cut off, which can prevent the insulating sleeve from shaking when cutting, thereby affecting the flatness of the cut surface, thereby ensuring the quality of the insulating sleeve after cutting.

[0034] Working principle: insert the insulating sleeve to be cut into the device from the inlet 4. After determining the length to be cut, the device can be started. First, the cylinder 26 will drive the clamping plate 27 to fix the insulating sleeve, and then the driving motor 6 will drive the gear 7 to rotate, and the gear ring 8 meshing therewith will also rotate. When the gear ring 8 rotates, it will drive the tool holder 11 to rotate through the fixed column 14, so that the blade 12 is close to the outer surface of the insulating sleeve. With the restrictions of the insulating sleeve and the limiting groove 13, the turntable 10 will rotate with the gear ring 8, thereby driving the blade 12 to perform circular cutting on the insulating sleeve. The cut insulating sleeve will fall from the outlet 5, and the driving motor 6 will reverse a little before the end of the operation to reset the tool holder 11 and the blade 12. The staff can push the insulating sleeve again to perform continuous cutting. The blade 12 will be worn after long-term use, affecting the sharpness of the cutting. At this time, the blade 12 can be removed by using the installation mechanism and replaced with a new blade 12 to ensure the sharpness of the blade 12.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
