[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-6 A cutting device for cable protection plastic tubes includes a base plate 1, and two clamping and feeding mechanisms are symmetrically arranged on the top of the base plate 1 for clamping and feeding the cable protection plastic tubes.

[0027] The clamping and feeding mechanism includes fixed plates 3 symmetrically installed on the top of the base plate 1. The opposite surfaces of the two fixed plates 3 are each equipped with a first electric telescopic rod 4. The piston rod end of the first electric telescopic rod 4 is equipped with a roller frame 5. An electric roller 6 is rotatably installed on the roller frame 5. An annular arc groove 7 that fits against the outer wall of the cable protection plastic tube is opened on the rolling surface of the electric roller 6.

[0028] The top of the base plate 1 is equipped with a cutting mechanism for cutting the cable protection plastic tube.

[0029] As a technical optimization of this utility model, the cutting mechanism includes a support column 8 installed on the top of the base plate 1, a top plate 9 installed on the top of the support column 8, a second electric telescopic rod 12 rotatably installed on the bottom of the top plate 9, an mounting plate 13 installed at the end of the piston rod of the second electric telescopic rod 12, and a cutting blade 22 for cutting the cable protection plastic tube rotatably installed at the bottom of the mounting plate 13.

[0030] As a technical optimization of this utility model, a first connecting plate 14 and a second connecting plate 15 are symmetrically installed on the bottom of the mounting plate 13, and the cutting blade 22 is rotatably installed between the first connecting plate 14 and the second connecting plate 15.

[0031] As a technical optimization of this utility model, a second motor 19 is installed on the side of the first connecting plate 14 away from the cutting blade 22. The output shaft of the second motor 19 passes through the first connecting plate 14 and is connected to the mounting shaft 21. The cutting blade 22 is fixedly sleeved on the mounting shaft 21. The mounting shaft 21 facilitates the installation of the cutting blade 22. The second motor 19 facilitates the rotation of the mounting shaft 21, causing the cutting blade 22 to rotate and cut the cable protection plastic tube.

[0032] As a technical optimization of this utility model, a bearing 20 is installed on the side of the second connecting plate 15 near the cutting blade 22, and the end of the mounting shaft 21 is installed in the inner ring of the bearing 20. The bearing 20 can provide guidance for the mounting shaft 21 and improve the stability of the mounting shaft 21 when it rotates.

[0033] As a technical optimization of this utility model, a first motor 10 is installed on the top of the top plate 9. The output shaft of the first motor 10 passes through the top plate 9 and is connected to the mounting plate 11. A second electric telescopic rod 12 is installed at the bottom of the mounting plate 11. The mounting plate 11 facilitates the connection between the second electric telescopic rod 12 and the output shaft of the first motor 10.

[0034] As a technical optimization of this utility model, a fixing rod 18 is installed on the top of the mounting plate 11, and a slider 17 is installed on the top of the fixing rod 18. An annular groove 16 is opened at the bottom of the top plate 9, and the slider 17 is slidably installed in the groove 16. Two sets of mounting holes 2 are symmetrically opened on the top of the bottom plate 1. Through the cooperation of the slider 17 and the groove 16, the mounting plate 11 can be guided when rotating, thereby improving the stability of the rotation of the mounting plate 11. The mounting holes 2 can facilitate the fixing of the bottom plate 1, thereby facilitating the installation and fixing of this device.

[0035] When using this invention, if it is necessary to cut the cable protection plastic tube, firstly, place the cable protection plastic tube to be cut between two electric rollers 6, and simultaneously activate two sets of first electric telescopic rods 4. The piston rods of the corresponding two first electric telescopic rods 4 extend and drive the corresponding two electric rollers 6 to move closer to each other until the cable protection plastic tube to be cut is located in the arc-shaped groove 7 opened in the rolling surface of the two electric rollers 6. The two corresponding electric rollers 6 clamp the cable protection plastic tube, which can clamp and fix the cable protection plastic tube and ensure the stability of the cable protection plastic tube during cutting.

[0036] At this time, two electric rollers 6 are started simultaneously. One electric roller 6 rotates clockwise and the other electric roller 6 rotates counterclockwise. The rotation of the two electric rollers 6 feeds the cable protection plastic tube clamped and fixed between the two electric rollers 6. This allows the cable protection plastic tube to be cut to be transported between the two electric rollers 6 automatically, eliminating the need for manual feeding of the cable protection plastic tube. This avoids the problem of injury from the cutting blade 22 and improves safety when cutting the cable protection plastic tube.

[0037] The cable protection plastic tube continues to be fed until its end enters between two clamping and feeding mechanisms. The two clamping and feeding mechanisms clamp and fix the cable protection plastic tube before feeding it, improving the stability of the feeding process. The feeding continues until the end of the cable protection plastic tube is fed below the cutting blade 22, and the cutting part of the cable protection plastic tube is below the cutting blade 22. At this time, the second motor 19 is started, and the output shaft of the second motor 19 drives the mounting shaft 21 to rotate, which in turn causes the cutting blade 22 to rotate. At this time, the second electric telescopic rod 12 is started, and the piston rod of the second electric telescopic rod 12 pushes the mounting plate 13 down, which in turn causes the cutting blade 22 to move down to cut the cable protection plastic tube.

[0038] Furthermore, when it is necessary to cut the cable protection plastic tube at different angles, the first motor 10 can be started. The output shaft of the first motor 10 drives the mounting plate 11 to rotate. The rotation of the mounting plate 11 drives the second electric telescopic rod 12, the mounting plate 13 and the cutting blade 22 to rotate, thereby adjusting the cutting angle of the cutting blade 22. This allows the cable protection plastic tube to be cut at different angles, improving the versatility of the device in use and enabling the cable protection plastic tube to be cut at different angles.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
