Description
Technical Field
[0001] This utility model relates to the field of cable sheathing cutting technology, and in particular to a high-speed cutting device with anti-skid blade. Background Technology
[0002] Cable sheathing refers to the protective or insulating material used in the manufacturing process of cables (wires) to wrap around the conductor or cable core. Its main function is to provide electrical insulation, mechanical protection, weather resistance, and flame retardancy. The slitting of cable sheathing is an important preliminary process in cable manufacturing. The slitting quality directly affects the stability of subsequent processes such as wrapping and extrusion. The slitting of cable sheathing requires the use of a slitting machine to cut the cable sheathing into narrow strips according to the required width to meet the production needs of different specifications of cables.
[0003] When cutting cable sheathing, a slitting knife is required. However, the slitting knife is usually fixed in position using spring clips and other springs. Due to factors such as knife wear or improper installation, the slitting knife may jump and deviate irregularly during cutting, resulting in a "skipping knife" phenomenon. Therefore, a high-speed slitting device to prevent skipping knife is proposed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-speed slitting device that prevents knife skipping, effectively solving the deficiencies of the prior art.
[0005] To achieve the above objectives, one embodiment of this utility model provides a high-speed slitting device for preventing knife skipping, including a support column for mounting the cutter, a cutter fixing seat mounted on the outer wall of the support column, a protruding ring mounted on one side of the cutter fixing seat, a cutter body mounted together between the protruding ring and the cutter fixing seat, two clamping semi-rings provided on the side of the cutter body away from the cutter fixing seat, a reinforcing ring for supporting the cutter body installed between the adjacent sides of the cutter body, the cutter fixing seat, and the clamping semi-rings, a plurality of first bolts rotatably mounted on one side of the two clamping semi-rings, the plurality of first bolts passing through the cutter body and threadedly connected to the cutter fixing seat, a locking ring mounted on the side of the cutter fixing seat away from the cutter body, a second bolt rotatably mounted on one end of the locking ring, the second bolt being threadedly connected to the cutter fixing seat.
[0006] Preferably, in any of the above embodiments, the outer wall of the support column is provided with four limiting slots, which are opened along the length of the support column. The inner wall of the tool holder is equipped with a limiting block that slides with the limiting slots. By using this embodiment, the limiting block can slide horizontally along the four limiting slots, ensuring the smoothness of the sliding of the tool holder. The slidable connection between the limiting block and the limiting slot is used for torque transmission, driving the tool holder and the cutting body to rotate synchronously, and performing slitting processing on the cable sheath.
[0007] Preferably, in any of the above solutions, the side of the cutter fixing seat near the protruding ring is provided with a guide groove, and the sides of the two clamping half-rings are each equipped with a guide protrusion that mates with the guide groove. This solution facilitates the limiting of the installation of the two clamping half-rings. When the guide protrusion enters the interior of the guide groove, it improves the coaxiality between the clamping half-ring and the support column, which facilitates the stable pressure applied to the reinforcing ring. This allows the two reinforcing rings to stably clamp the cutter body, improving the structural stability of the cutter body and preventing irregular jumping during the cutting of cable sheathing.
[0008] Preferably, in any of the above solutions, the outer edge of the tool holder and the outer edge of the two clamping semi-rings are stepped. The inner walls of the two reinforcing rings abut against the stepped outer surfaces of the tool holder and the clamping semi-rings. This solution facilitates the installation of the two reinforcing rings by increasing the limit, thereby ensuring stable installation. After the two clamping semi-rings are connected to the tool holder by multiple first bolts, it is easier to press the two reinforcing rings against the cutter body, thereby achieving uniform pressure on the cutter body and preventing irregular deviations during cutting operations.
[0009] Preferably, the cross-sections of the two reinforcing rings are T-shaped, and multiple reinforcing ribs are installed on one side of the inner wall of the two reinforcing rings. This design helps to improve the structural stability of the reinforcing rings and prevent deformation.
[0010] Preferably, in any of the above embodiments, the two sides of the cutter body are in contact with the sides of the two reinforcing rings, and a gap is left between the two sides of the cutter body and the sides of the tool holder and the two clamping half-rings. This embodiment facilitates a stable fit between the two sides of the cutter body and the sides of the reinforcing rings. By leaving a gap between the two sides of the cutter body and the sides of the tool holder and the two clamping half-rings, multiple first bolts can be tightened, so that the pressure of the two clamping half-rings is applied to the cutter body through the two reinforcing rings, thus preventing the cutter body from "jumping".
[0011] This utility model has the following advantages:
[0012] 1. This anti-skid high-speed cutting device comprises a tool fixing seat, a cutting body, two raised rings, and two clamping half-rings. The raised rings are mounted on the side of the tool fixing seat, and the middle part of the cutting body is slidably mounted on the outer circumference of the raised rings. The two raised rings are located on both sides of the cutting body. By tightening multiple first bolts, the two reinforcing rings are pushed to clamp the cutting body. At the same time, the reinforcing rings are larger in size, clamping and fixing the shape of the cutting body to maintain the stability of the cutting body shape and avoid irregular deviation during the cutting operation, thereby preventing the cutting body from "skipping" and effectively solving the problems existing in the prior art.
[0013] 2. This anti-skid high-speed slitting device, by setting a cutter fixing seat and two clamping half-rings, has a guide groove on the side of the cutter fixing seat and guide protrusions on the sides of the two clamping half-rings, which facilitates the limiting of the installation of the two clamping half-rings, ensures the coaxiality of the two, and applies uniform pressure to the reinforcing rings to ensure uniform pressure on the cutter body. By setting two reinforcing rings, multiple reinforcing ribs are installed on one side of the inner wall of the two reinforcing rings, thereby improving the structural stability of the two reinforcing rings and preventing their own deformation, thus completing the stable clamping of the cutter body and meeting the requirements of high-speed slitting.

Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.
[0022] like Figures 1 to 6 As shown, a high-speed slitting device for preventing knife skipping includes a support column 1 for mounting the cutter, and a cutter fixing seat 5 is mounted on the outer wall of the support column 1.
[0023] A raised ring 12 is installed on one side of the tool holder 5. The cutter body 7 is installed together between the raised ring 12 and the tool holder 5. Two clamping half rings 10 are provided on the side of the cutter body 7 away from the tool holder 5. A reinforcing ring 3 is installed between the adjacent sides of the cutter body 7, the tool holder 5, and the clamping half rings 10 to support the cutter body 7. Multiple first bolts 11 are rotatably installed on one side of the two clamping half rings 10. The multiple first bolts 11 pass through the cutter body 7 and are threadedly connected to the tool holder 5.
[0024] A locking ring 4 is installed on the side of the tool holder 5 away from the cutter body 7. A second bolt 6 is rotatably installed on one end of the locking ring 4, and the second bolt 6 is threadedly connected to the tool holder 5. Half of the circumference of the locking ring 4 is fixedly connected to the side of the tool holder 5, and a gap is left between the other half of the length of the locking ring 4 and the side of the tool holder 5. The second bolt 6 is then tightened to bring the two ends of the locking ring 4 closer together, thereby locking the support column 1 and stabilizing the position of the tool holder 5. After the support column 1 rotates circumferentially, it facilitates the synchronous rotation of the tool holder 5 and the cutter body 7 to complete the slitting process of the cable sheath and avoid the "jumping" phenomenon of the cutter body 7.
[0025] The material of the cutter holder 5 is generally high-speed steel, cemented carbide, etc., which has high rigidity, wear resistance, thermal stability and long service life. It is used to provide a stable mounting base for the cutter body 7. After being locked with the cutter holder 5 by two clamping half rings 10, it is easy to stably clamp the cutter body 7 to meet the high-speed cutting requirements.
[0026] The outer wall of the support column 1 is provided with four limiting slots 2, which are opened along the length of the support column 1. The inner wall of the tool fixing seat 5 is equipped with a limiting block 9 that slides with the limiting slots 2. As an optional technical solution of this utility model, this makes it easy for the limiting block 9 to slide horizontally along the four limiting slots 2, ensuring the smoothness of the sliding of the tool fixing seat 5. The limiting block 9 is slidably connected with the limiting slots 2 for torque transmission, driving the tool fixing seat 5 and the cutting body 8 to rotate synchronously, and to perform slitting processing on the cable sheath.
[0027] The tool holder 5 has a guide groove 13 on its side near the protruding ring 12. The two clamping half rings 10 are each equipped with a guide protrusion 14 that cooperates with the guide groove 13. As an optional technical solution of this utility model, this facilitates the limiting of the installation of the two clamping half rings 10. When the guide protrusion 14 enters the interior of the guide groove 13, it improves the coaxiality between the clamping half ring 10 and the support column 1, which facilitates the stable pressure on the reinforcing ring 3. Thus, the two reinforcing rings 3 stably clamp the cutter body 7, improve the structural stability of the cutter body 7, and prevent irregular jumping during the cutting of cable sheathing.
[0028] The outer edge of the tool holder 5 and the outer edge of the two clamping half-rings 10 are both stepped. The inner walls of the two reinforcing rings 3 abut against the stepped outer surfaces of the tool holder 5 and the clamping half-rings 10. As an optional technical solution of this utility model, this facilitates the installation of the two reinforcing rings 3 and improves the limit, thereby making the reinforcing rings 3 installed stably. At the same time, after the two clamping half-rings 10 are connected to the tool holder 5 by multiple first bolts 11, it is convenient to press the two reinforcing rings 3 against the cutter body 7, thereby achieving uniform pressure on the cutter body 7 and avoiding irregular deviation when the cutter body 7 is cutting.
[0029] The cross-sections of the two reinforcing rings 3 are T-shaped, and multiple reinforcing ribs 8 are installed on one side of the inner wall of the two reinforcing rings 3. As an optional technical solution of this utility model, this can help improve the structural stability of the reinforcing rings 3, improve the structural stability of the two reinforcing rings 3, and avoid deformation of themselves.
[0030] The two sides of the cutter body 7 are in contact with the sides of the two reinforcing rings 3. There is a gap between the two sides of the cutter body 7 and the sides of the cutter fixing seat 5 and the sides of the two clamping half rings 10. As an optional technical solution of this utility model, this makes it easier to make the two sides of the cutter body 7 fit stably with the sides of the reinforcing rings 3. By leaving a gap between the two sides of the cutter body 7 and the sides of the cutter fixing seat 5 and the sides of the two clamping half rings 10, the multiple first bolts 11 are tightened, so that the pressure of the two clamping half rings 10 is pressed against the cutter body 7 through the two reinforcing rings 3, thus avoiding the "switching" phenomenon of the cutter body 7.
[0031] This anti-skid high-speed slitting device requires the following steps to be used:
[0032] 1) During installation, install a reinforcing ring 3 on the stepped position on the outer circular surface of the tool holder 5;
[0033] 2) Install the cutter body 7 on the protruding ring 12, and make one side of the cutter body 7 fit against the side of the reinforcing ring 3;
[0034] 3) Align the two ends of the two clamping half rings 10, and then install them together with another reinforcing ring 3 on the side of the cutter body 7, while installing the middle part of the reinforcing ring 3 on the stepped position of the two clamping half rings 10.
[0035] 4) Install the two guide protrusions 14 together inside the guide groove 13, tighten them with multiple first bolts 11, and assemble them into an assembly;
[0036] 5) Install the assembly of the tool holder 5 and the cutter body 7 on the support column 1, measure the designated position, and tighten the second bolt 6 to complete the overall position locking.
[0037] In summary, during use, the user configures the tool holder 5, the cutter body 7, two raised rings 12, and two clamping half-rings 10. The raised rings 12 are mounted on the side of the tool holder 5, and the middle of the cutter body 7 is slidably mounted on the outer surface of the raised rings 12. The two raised rings 12 are located on both sides of the cutter body 7. By tightening multiple first bolts 11, the two reinforcing rings 3 are pushed to clamp the cutter body 7. Simultaneously, the reinforcing rings 3, being larger in size, clamp and fix the shape of the cutter body 7, maintaining its shape stability and preventing irregular displacement during cutting operations, thus avoiding "switching" of the cutter body 7. This invention addresses the problem of existing technologies by setting up a tool holder 5 and two clamping half-rings 10. The tool holder 5 has a guide groove 13 on its side, and the two clamping half-rings 10 have guide protrusions 14 on their sides. This facilitates the installation and positioning of the two clamping half-rings 10, ensures their coaxiality, and applies uniform pressure to the reinforcing rings 3, ensuring uniform pressure on the cutter body 7. By setting up two reinforcing rings 3, multiple reinforcing ribs 8 are installed on one side of the inner wall of the two reinforcing rings 3, thereby improving the structural stability of the two reinforcing rings 3 and preventing deformation. This achieves stable clamping of the cutter body 7, meeting the requirements of high-speed slitting.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
