Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of cable processing technology, and more specifically, to a cable insulation cutting device. Background Technology

[0002] As a core piece of equipment for cable processing and maintenance, the cable insulation cutting device is specifically designed to remove the outer insulation layer of cables to meet the needs of cable connection, fault detection, line maintenance, and other operations. Through the cooperation of the cutting head, clamping, and transmission mechanism, it can cut and peel off the insulation layer of cables of different specifications (such as 10KV / 35KV power cables and ribbon cables in the microelectronics industry). It is widely used in power engineering, communication equipment installation, electronic manufacturing and other fields. However, the above-described implementation methods still have the following problems. In terms of blade height adjustment, traditional devices often use a fixed blade design or require manual disassembly and replacement of parts to adjust the height. When faced with insulation layers of different thicknesses, such as cross-linked polyethylene insulation layers and PVC insulation layers, thick cables and thin ribbon cables, it is impossible to accurately match the cutting depth. This can easily lead to problems such as cutting too deep and damaging the metal conductor, resulting in damage to the cable's conductivity, or cutting too shallowly and failing to completely remove the insulation layer, increasing the rework rate. At the same time, for insulation layers with uneven thickness in some areas, the fixed-height blade is difficult to adjust flexibly, which can easily cause blade jamming, insulation layer tearing and other malfunctions. Furthermore, multiple dedicated devices are required for different specifications of cables, increasing equipment procurement costs and tool switching time during operation, and failing to meet the needs of efficient and universal operation.

A connecting strip is fixedly installed on the left side of the top of the connecting plate. The outer surface of the connecting strip is movably sleeved with the inner surface of the support frame. A serrated groove is opened at the front end of the connecting strip. A fixing block is movably sleeved on the outer surface of the connecting strip. Slider blocks are fixedly connected to both sides of the connecting plate. A limit groove is opened inside the fixing block. A limit block is movably sleeved inside the limit groove. A serrated block is fixedly connected to the rear end of the limit block. A first return spring and a pull rod are fixedly connected to the front end of the limit block. The outer surface of the serrated block is movably connected to the inner surface of the serrated groove. The front end of the first return spring is fixedly connected to the front side inside the limit groove. The outer end of the pull rod passes through the limit groove and extends to the outside of the limit groove. The inner end of the fixing block is movably connected to the outer surface of the support frame.

[0005] As a preferred embodiment of this utility model, the two supporting plates are provided with grooves on their opposite surfaces, and the inner surface of the grooves is movably connected to the outer surface of the slider.

[0006] As a preferred technical solution of this utility model, a U-shaped plate is fixedly connected to the front side of the top of the workbench, and a limit wheel is movably sleeved inside the U-shaped plate.

[0007] As a preferred embodiment of this utility model, the number of the limiting wheels is two, and the outer surface of both limiting wheels is provided with guide grooves.

[0008] As a preferred embodiment of this utility model, a fixed plate is movably sleeved inside the U-shaped plate, and a second return spring is fixedly connected inside the fixed plate.

[0009] As a preferred embodiment of this utility model, there are two second reset springs, and the bottom ends of both second reset springs are fixedly connected to the bottom end inside the U-shaped plate.

[0010] As a preferred embodiment of this utility model, there are two fixing plates, and a fixing frame is fixedly installed on the top of each of the two fixing plates.

[0011] As a preferred embodiment of this utility model, the fixed frame is movably fitted with four pulleys.

[0012] As a preferred embodiment of this utility model, each of the four pulleys is fixedly connected to a pressing wheel at its inner end, and the number of pressing wheels is four.

[0013] As a preferred technical solution of this utility model, each pair of the four extrusion rollers forms a group, and a second pulley is fixedly connected between each group of extrusion rollers. The outer surface of the extrusion rollers is rough.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, by setting rollers, cutter heads, screws, and sawtooth blocks, the entire assembly moves the connecting plate by rotating the screw, thereby adjusting the height of the cutter head. After adjustment, the pull rod moves the limit block and sawtooth block, compressing the first reset spring. The limit of the fixing block and connecting strip opens, allowing the fixing block to move up and down, fitting the fixing block against the surface of the support frame to complete the fixation between the support frame and the connecting plate. The insulation layer thickness of cables of different specifications varies greatly. The adjustable height allows the cutter head to accurately cut into the insulation layer without touching the internal metal conductor, preventing conductor scratches and wire breakage, ensuring the conductivity of the cable. Furthermore, the adjustable height allows for flexible adjustment of the cutting force of the cutter head, avoiding jamming due to excessive material hardness or incomplete stripping due to excessive softness.

[0015] 2. In this disclosure, by setting a limiting wheel, a second return spring, a first pulley, and a squeezing wheel, the cable passes between the limiting wheel and the squeezing wheel, stretching the second return spring. At this time, the cable is restricted between the first pulley and the second pulley. With the guidance of the limiting wheel and the elasticity of the second return spring, the cable is clamped, preventing it from deviating or sliding axially under the action of the cutter head. This ensures that the cutter head always cuts the insulation layer along the preset depth and path, effectively avoiding the problem of cutting off or shallow cutting caused by cable shaking. It ensures that the insulation layer stripping length and cut flatness of the same batch or the same cable are consistent, and there is no need to rely on the operator's experience to judge the path. The overall cable direction can be guided by the limiting wheel, which can reduce human error. Attached Figure Description

[0025] like Figures 1 to 7The diagram illustrates a cable insulation cutting device according to an embodiment of this disclosure, comprising a workbench 1, a support plate 2 fixedly connected to the top of the workbench 1, a servo motor 3 fixedly mounted on the outer surface of the support plate 2, the bottom end of the servo motor 3 fixedly connected to the top of the workbench 1, a rotating shaft 28 fixedly connected to the other end of the output shaft of the servo motor 3, a roller 4 fixedly connected to the outer surface of the rotating shaft 28, and the outer surface of the rotating shaft 28 movably sleeved with the inner surface of the support plate 2, two support plates 2, a connecting plate 5 movably connected between the two support plates 2, a cutter head 6 fixedly mounted on the bottom end of the connecting plate 5, a support frame 7 fixedly connected to the top of each of the two support plates 2, a screw 8 threaded inside the support frame 7, the bottom end of the screw 8 movably sleeved with the top of the connecting plate 5, and a fixedly mounted... The connecting plate 5 is equipped with a connecting strip 9, the outer surface of which is movably connected to the inner surface of the support frame 7. A serrated groove 10 is provided at the front end of the connecting strip 9. A fixing block 11 is movably connected to the outer surface of the connecting strip 9. Slider blocks 12 are fixedly connected to both the left and right sides of the connecting plate 5. A limiting groove 14 is provided inside the fixing block 11. A limiting block 15 is movably connected inside the limiting groove 14. A serrated block 16 is fixedly connected to the rear end of the limiting block 15. A first return spring 18 and a pull rod 17 are fixedly connected to the front end of the limiting groove 14. The outer surface of the serrated block 16 is movably connected to the inner surface of the serrated groove 10. The front end of the first return spring 18 is fixedly connected to the front side inside the limiting groove 14. The outer end of the pull rod 17 passes through the limiting groove 14 and extends to the outside of the limiting groove 14. The inner end of the fixing block 11 is movably connected to the outer surface of the support frame 7.

[0026] When cutting the cable insulation layer, the height of the cutter head 6 can be adjusted to meet the needs of cutting insulation layers of different thicknesses. During use, the screw 8 needs to be rotated for operation. The handle at the top of the screw 8 can be held for operation. The bottom end of the screw 8 is tightly connected to the connecting plate 5. The movement of the screw 8 can indirectly drive the cutter head 6 to move to achieve height adjustment. When the screw 8 moves, the fixing blocks 11 on the connecting strip 9 need to be opened. There are two fixing blocks 11, which are arranged vertically and fit tightly against the support frame 7 to ensure the fixed position of the screw 8 on the support frame 7 and ensure the stability of the cutter head 6 during the cutting process.

[0027] In some examples, grooves 13 are provided on the opposite surfaces of the two support plates 2, and the inner surface of the grooves 13 is movably connected to the outer surface of the slider 12.

[0028] The connecting plate 5 is limited by the slider 12, which ensures the stability of the connecting plate 5 when it moves between the two support plates 2, thereby meeting the need for height adjustment of the cutter head 6.

[0029] In some examples, a U-shaped plate 19 is fixedly connected to the front side of the top of the workbench 1, and a limit wheel 20 is movably sleeved inside the U-shaped plate 19.

[0030] There are two limit wheels 20, arranged one in front of the other. The design of the limit wheels 20 can ensure the consistency of the position during subsequent cable cutting and prevent easy movement and misalignment.

[0031] In some examples, there are two limit wheels 20, and the outer surfaces of both limit wheels 20 are provided with guide grooves 21.

[0032] Each limiting wheel 20 has two guide grooves 21 on its surface. The two guide grooves 21 are arranged left and right to place the cable and limit its movement so that it can only move back and forth within the guide grooves 21.

[0033] In some examples, a fixed plate 22 is movably sleeved inside the U-shaped plate 19, and a second return spring 23 is fixedly connected inside the fixed plate 22.

[0034] The design of the fixing plate 22 increases the contact area of ​​the U-shaped plate 19 and improves the stability of the connection. There are two fixing plates 22 arranged side by side.

[0035] In some examples, there are two return springs 23, and the bottom ends of both return springs 23 are fixedly connected to the bottom end inside the U-shaped plate 19.

[0036] When the cable passes through the U-shaped plate 19, the two fixed plates 22 will move upward. At this time, the second return spring 23 will be stretched, and the cable will be clamped by the elastic force of the second return spring 23.

[0037] In some examples, there are two fixing plates 22, and a fixing bracket 24 is fixedly installed on the top of each fixing plate 22.

[0038] When the two fixing plates 22 move upward, they will drive the fixing frame 24 to move together. At this time, the fixing frame 24 will generate a downward thrust due to the elastic force of the second return spring 23, which facilitates the subsequent clamping of the cable.

[0039] In some examples, the internal movable sleeve of the fixing frame 24 has four pulleys 25.

[0040] Before cutting, the cable is limited between the U-shaped plate 19 and the fixing frame 24, eliminating the need for manual support to maintain stability. The cable is limited by the inside of the first pulley 25.

[0041] In some examples, the inner ends of the four pulleys 25 are fixedly connected to the compression rollers 26, and there are four compression rollers 26.

[0042] The cable passes over the outer surface of the extrusion roller 26, and the guide groove 21 and the first pulley 25 keep the cable within a limited range, which can prevent cutting deviation caused by cable swaying.

[0043] In some examples, each pair of extrusion rollers 26 is grouped together, and a second pulley 27 is fixedly connected between each group of extrusion rollers 26. The outer surface of the extrusion rollers 26 is rough.

[0044] The rough outer surface of the extrusion roller 26 increases the friction between it and the cable, improves the clamping effect, and prevents the cable from slipping off due to external forces.

[0045] Working principle and usage process of this utility model: During use, the operator places the cable in the roller 4. Starting the servo motor 3 causes the output shaft to rotate the roller 4, which in turn moves the cable backward. As the cable moves backward, it contacts the cutter head 6 for cutting. The cable continues to move until the cutting is complete. When cutting cable insulation layers of different thicknesses, the height of the cutter head 6 can be adjusted to meet the requirements. Rotating the screw 8 moves the connecting plate 5, which is stabilized by the slider 12. The connecting plate 5 moves the cutter head 6, allowing for height adjustment. Once the desired height is reached, pulling the pull rod 17 moves the limit block 15, compressing the first reset spring 1. 8. During the movement of the limiting block 15, the sawtooth block 16 will move together. When the sawtooth block 16 moves, it will disengage from the sawtooth groove 10, opening the fixation between the fixing block 11 and the connecting strip 9. The fixing block 11 can move. There are two fixing blocks 11 arranged vertically. Move the two fixing blocks 11 to fit against the upper and lower sides of the support frame 7. After fitting, the spring force of the first reset spring 18 will drive the limiting block 15 to reset, so that the sawtooth block 16 and the sawtooth groove 10 will be engaged again. At this time, the fixing block 11 and the connecting strip 9 are in a fixed state. At the same time, the support frame 7 and the connecting plate 5 are also in a fixed state, ensuring that the position of the cutter head 6 is fixed during the cutting process and will not be affected by external vibrations and move, thus improving the stability during the cutting process.

[0046] Before cutting, the cable needs to be clamped. The operator places the cable between the extrusion wheel 26 and the limiting wheel 20. The sawtooth block 16 moves upward under the push of the cable, stretching the second return spring 23. The cable continues to move until it passes between the sawtooth groove 10 and the limiting groove 14. The cable is restricted between the first pulley 25 and the second pulley 27. The cable is limited by the guide groove 21 and the elasticity of the second return spring 23. The rough surface of the extrusion wheel 26 increases the friction between it and the cable. As the cable moves, the combination of the first pulley 25, the extrusion wheel 26, the second pulley 27 and the limiting wheel 20 also rotates. While limiting the cable, it does not affect the normal cutting of the cable, thus improving the overall safety.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
