Description

Technical Field

[0001] The utility model relates to the technical field related to cable protection tube production and processing equipment, in particular to a cutting machine for cable protection tube production and processing. Background Art

[0002] Cable protection tube refers to a metal protection tube with a certain mechanical strength that is laid on the outer layer of the cable to prevent the cable from being damaged. The cable protection tube is mainly installed in the section where the communication cable and the power line intersect to prevent the power line from being broken and causing a short circuit accident, causing the communication cable and the wire rope to be electrified, so as to protect the cable, switch, movement board, and even the whole machine from being burned out. It also plays a certain isolation role against the magnetic field interference of the power line. During the production and processing of cable protection tubes, a cutting device is generally required to cut and process it, as follows.

[0003] After searching, the patent with the authorization publication number CN220196477U discloses a cutting machine for the production and processing of power cable protection tubes, including a base, a driving assembly and a blade. Both sides of the top of the base are provided with an annular fixing seat, and the bottom of the inner wall of the annular fixing seat is fixedly connected with a cylinder, and one end of the cylinder output shaft is fixedly connected with a support plate. The utility model relates to the technical field of cable protection tube production. The cutting machine for the production and processing of power cable protection tubes passes the cable protection tube through two annular fixing seats in sequence, and the cylinder drives the support plate to support the bottom of the protection tubes of different sizes, so that the protection tube can be kept in the center of the annular fixing seat, which is conducive to the clamping of the clamping plate, and then by moving the locking mechanism on the adjusting rod, the adjusting rod can drive the clamping plate to move in the annular fixing seat, and the cable protection tubes of different sizes are clamped and positioned, the positioning is more stable, and the use is more flexible, which increases the applicable scope of the clamping of the cutting machine.

[0004] However, the above patent still has the following aspects that can be optimized:

[0005] Although it can be applied to the cutting and processing of protective tubes of various diameters, it is necessary to operate multiple adjustment rods to ensure the stability of the protective tube when clamping and fixing the protective tube. For example, three different adjustment rods need to be adjusted inside a single annular fixing seat, and six different adjustment rods need to be adjusted for two annular fixing seats, so as to adjust the positions of multiple clamping plates, resulting in the entire clamping and fixing operation process being time-consuming, labor-intensive, and inefficient. In addition, since the adjustment rod is locked and fixed by the engagement between the arc clamping plate and the clamping groove, and since the sizes of different protective tubes are different and the clamping grooves are designed with equal spacing, it is difficult to ensure that after the clamping plate and the protective tube are abutted, the positions of the arc clamping plate and the clamping groove can be just matched to lock and fix the adjustment rod. Finally, since it only has a single cutting mechanism to cut the protective tube from top to bottom, when the size of the protective tube is large, due to the limited size of the cutter, a single cut may not be able to completely cut off the protective tube, and the position of the protective tube needs to be readjusted for secondary cutting, resulting in further reduced work efficiency. Therefore, its overall structure needs to be improved and its practicality needs to be improved. Utility Model Content

[0006] The utility model aims to provide a cutting machine for producing and processing cable protection tubes, so as to solve the problem that although the above-mentioned patent can be applied to the cutting and processing of protection tubes of various diameters, when clamping and fixing the protection tubes, in order to ensure the stability of the protection tubes, multiple adjustment rods need to be operated. For example, three different adjustment rods need to be adjusted inside a single annular fixing seat, and six different adjustment rods need to be adjusted for two annular fixing seats, so as to adjust the positions of multiple clamping plates, resulting in the whole clamping and fixing operation process being time-consuming, labor-intensive and inefficient. In addition, since the adjustment rods are connected through arc-shaped clamping plates and clamping grooves, However, due to the different sizes of protective tubes and the equally spaced design of the slots, it is difficult to ensure that after the splint and the protective tube are in contact, the positions of the arc-shaped clamping plate and the slots can just match to lock and fix the adjusting rod. Finally, since only a single cutting mechanism is provided to cut the protective tube from top to bottom, when the size of the protective tube is large, due to the limited size of the cutter, a single cut may not be able to completely cut off the protective tube, and the position of the protective tube needs to be readjusted for a second cut, which further reduces the work efficiency. Therefore, its overall structure needs to be improved and its practicality needs to be improved.

Due to the design of the V-groove at the bearing seat and the clamping seat, it can not only be suitable for protective tubes of various diameters, but also effectively ensure the stability of the protective tube after clamping and fixing. During cutting processing, the protective tube can be cut from top to bottom by the first cutting structure. If it can be completely cut off, there is no need to start the second cutting structure. If it cannot be completely cut off, the second cutting structure can be started after the first cutting operation is completed, and the protective tube is cut for the second time from bottom to top, ensuring that the protective tube can be completely cut off without re-adjusting the position of the protective tube, thereby further improving the processing efficiency and having high overall practicality.
