Description

Technical Field

[0001] This utility model relates to the field of cable circumferential cutting technology, and in particular to a cable circumferential cutting device. Background Technology

[0002] A cable circumferential cutter is a specialized tool used to cut the outer sheath or insulation layer of cables, widely used in the power, telecommunications, and construction industries. Its working principle involves using a rotating blade or ring-shaped cutting mechanism to make a uniform cut along the circumference of the cable, ensuring a clean cut without damaging the internal conductor. This device typically features adjustable cutting depth to accommodate cables of different diameters, and is simple and efficient to operate.

[0003] A search revealed that patent CN219321968U discloses a cable circumferential cutting device. This device adjusts the position of the cutting blade up and down to the cable surface, and then uses a circumferential cutting ring to rotate the blade, thus achieving the circumferential cutting function. The adjustment of the cutting blade and the rotation of the ring block are both achieved electrically and via an electric telescopic rod, ensuring operational precision.

[0004] However, the aforementioned device has the following drawbacks: Firstly, the device uses an electric telescopic rod three to move the cutter and pierce the cable sheath. Secondly, the electric telescopic rod three needs to rotate with the annular block, making it difficult to connect the electric telescopic rod three to power and control the piercing depth. Thirdly, after the cable circumferential cutting is completed, the electric telescopic rod two pushes the cable laterally to achieve longitudinal cutting. However, the travel of the electric telescopic rod two is limited, restricting the length that can be cut longitudinally. Therefore, further improvements are needed. To this end, we propose a cable circumferential cutting device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cable circumferential cutting device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cable circumferential cutting device, comprising a base plate, a gantry frame fixed on one side of the upper surface of the base plate, clamping components installed on both sides of the gantry frame, a vertical plate fixed on the upper surface of the base plate near the gantry frame, a cylinder rotatably connected through the top of the vertical plate via a bearing, a first motor for driving the cylinder to rotate fixed on the bottom surface of the vertical plate, a circular hole opened in the side wall of the cylinder, a cutting component provided on the surface of the cylinder near the circular hole, a flat plate fixed on the upper surface of the base plate away from the gantry frame, an opening opened in the middle of the flat plate, a material ejection component provided in the middle of the flat plate and its surface, and a control cabinet installed on the upper surface of the base plate.

[0007] Furthermore, the clamping assembly includes a first electrically operated telescopic rod fixed to the outer wall of the gantry frame, the telescopic end of the first electrically operated telescopic rod passing through the gantry frame and fixedly connected to a clamping plate.

[0008] Furthermore, a driven gear is fixed to the outer wall of the cylinder, and a driving gear is fixed to the output end of the first motor, with the driving gear meshing with the driven gear.

[0009] Furthermore, the cutting assembly includes a vertical tube fixed to the outside of a circular hole on the side wall of the cylinder, and a needle is slidably connected between the vertical tube and the inside of the circular hole, with scale lines provided on the surface of the needle.

[0010] Furthermore, a locking bolt is connected through the side wall of the vertical tube and rotated via a thread, with one end of the locking bolt inside the vertical tube fitting against the surface of the needle.

[0011] Furthermore, the unloading assembly includes a drive roller with a through opening, and the top of the drive roller is located on the upper surface of the flat plate. A side plate is fixed to the lower surface of the flat plate, and a second motor is fixed to the surface of the side plate. The output end of the second motor is fixedly connected to the drive roller. The unloading assembly also includes a top plate fixed to the top of the flat plate. A second electric telescopic rod is fixed to the upper surface of the top plate. A U-shaped wheel frame is fixed to the bottom telescopic end of the second electric telescopic rod, and a pressure roller is rotatably connected inside the wheel frame.

[0012] Furthermore, the surface of the drive roller is provided with raised ridges.

[0013] The beneficial effects of this utility model are:

[0014] 1. In use, this utility model includes a gantry frame, a clamping assembly, a vertical plate, a cylinder, a first motor, and a cutting assembly. First, the cable is clamped and fixed by the clamping assembly. Then, the needle is moved along the vertical tube so that it inserts into the cable sheath. The needle surface is marked with scale lines to accurately control the depth of the needle's penetration into the cable. The needle is then fixed with locking bolts. Finally, the cylinder is rotated by the motor to achieve circumferential cutting of the cable. The needle pierces the cable manually, eliminating the need to consider the issue of electrical connection, making the structure simpler.

[0015] 2. When using this utility model, a flat plate and a material ejection assembly are set up. After the cable is circumcised, the pressure roller and drive roller of the material ejection assembly are used to clamp the cable, and then the drive roller is used to drive the cable to move, so that the cable is ejected from the cylinder. During this process, the barbs are used to cut the cable longitudinally. This cutting method can cut a wider range of lengths. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-3 As shown, a cable circumferential cutting device is disclosed, comprising a base plate 1, a gantry frame 2 fixed on one side of the upper surface of the base plate 1, clamping components 3 installed on both sides of the gantry frame 2, a vertical plate 4 fixed on the upper surface of the base plate 1 near the gantry frame 2, a cylinder 5 rotatably connected to the top of the vertical plate 4 via a bearing, a first motor 6 for driving the cylinder 5 to rotate fixed on the bottom surface of the vertical plate 4, a circular hole opened on the side wall of the cylinder 5, a cutting component 7 provided on the surface of the cylinder 5 near the circular hole, a flat plate 8 fixed on the upper surface of the base plate 1 away from the gantry frame 2, an opening 81 opened in the middle of the flat plate 8, a material ejection component 9 provided in the middle of the flat plate 8 and its surface, and a control cabinet installed on the upper surface of the base plate 1.

[0024] In this embodiment, the control cabinet has a built-in PLC controller, specifically an S7-1200 series (small and medium-sized automation) CPU 1214C (6ES7214-1BG40-0XB0), which controls the operation of the various electronic components of the device.

[0025] The clamping assembly 3 includes a first electric telescopic rod 31 fixed to the outer wall of the gantry 2. The telescopic end of the first electric telescopic rod 31 passes through the gantry 2 and is fixedly connected to a clamping plate 32.

[0026] By controlling the two first electric telescopic rods 31 to extend simultaneously through the control cabinet, the cables passing through the cylinder 5 can be clamped and fixed using two clamping plates 32.

[0027] A driven gear 51 is fixed to the outer wall of the cylinder 5, and a driving gear 61 is fixed to the output end of the first motor 6. The driving gear 61 meshes with the driven gear 51.

[0028] In this embodiment, the first motor 6 is a geared motor. After starting the first motor 6, the cylinder 5 can be driven to rotate slowly, thereby stimulating the cutting component 7 to rotate.

[0029] The cutting assembly 7 includes a vertical tube 71 fixed to the outside of the circular hole on the side wall of the cylinder 5, and a needle 72 is slidably connected between the vertical tube 71 and the inside of the circular hole. The surface of the needle 72 is provided with scale lines.

[0030] In this embodiment, an end plate is provided at one end of the needle 72 located outside the cylinder 5. After the cable passes through the inside of the cylinder 5, the needle 72 can be moved along the vertical tube 71 by pressing the end plate, thereby allowing the needle 72 to pass through the cable sheath. Furthermore, the depth to which the needle 72 penetrates the cable sheath can be determined according to the scale lines, preventing the needle 72 from puncturing the internal structure of the cable.

[0031] The side wall of the vertical tube 71 is penetrated and connected by a locking bolt 73 via a threaded rotation. One end of the locking bolt 73 located inside the vertical tube 71 is in contact with the surface of the needle 72.

[0032] Once the needle 72 is inserted into the cable sheath, tighten the locking bolt 73 to press and fix the needle 72.

[0033] The unloading assembly 9 includes a drive roller 91 that passes through the opening 81, with the top of the drive roller 91 located on the upper surface of the plate 8. A side plate 10 is fixed to the lower surface of the plate 8, and a second motor is fixed to the surface of the side plate 10. The output end of the second motor is fixedly connected to the drive roller 91. The unloading assembly 9 also includes a top plate 92 fixed to the top of the plate 8. A second electric telescopic rod 93 is fixed to the upper surface of the top plate 92. A U-shaped wheel frame is fixed to the bottom telescopic end of the second electric telescopic rod 93, and a pressure roller 94 is rotatably connected inside the wheel frame.

[0034] After the cable passes between the drive roller 91 and the pressure roller 94, the second electric telescopic rod 93 is activated to drive the pressure roller 94 to descend. The pressure roller 94 and the drive roller 91 clamp the cable. Then the second motor is activated to drive the drive roller 91 to rotate. Under the action of friction, the drive roller 91 drives the cable to move, so that the cable exits from the cylinder 5. During this process, the needle 72 is used to cut the cable longitudinally.

[0035] The drive roller 91 has raised ridges on its surface. The raised ridges can increase the friction between the drive roller 91 and the cable.

[0036] Working principle: First, determine the thickness (h) of the cable sheath. Then, pass the cable through the cylinder 5 and clamping assembly 3 from one side of the unloading assembly 9. Next, start the first electric telescopic rod 31 to move the clamping plate 32 and use the clamping plate 32 to clamp and fix the cable. Then, press the needle 72 to insert into the cable sheath, with the reference scale line the same as h. Then tighten the locking bolt 73 to fix the needle 72. Then, start the first motor 6 to drive the cylinder 5 and the needle 72 to rotate, realizing the circumferential cutting of the cable. After the circumferential cutting is completed, start the second electric telescopic rod 93 to extend, and use the pressure roller 94 and drive roller 91 to clamp the cable. Then, start the first electric telescopic rod 31 to shorten, so that the clamping plate 32 releases the cable. Then, start the second motor to drive the drive roller 91 to rotate. Under the action of friction, the drive roller 91 drives the cable to move, so that the cable exits from the cylinder 5. During this process, the needle 72 is used to cut the cable longitudinally.

Clearly, many modifications and variations can be made based on the content of this specification.
