Description

Technical Field

[0001] This utility model relates to the field of power cable technology, specifically an automatic stripping device for power cables. Background Technology

[0002] In the process of power cable processing, it is often necessary to strip the insulation of power cables. The existing method is mostly to manually strip the outer insulation layer of the power cable using an electrician's knife. This method has the problems of high labor intensity, poor stripping quality, and high defect rate of power cables.

[0003] For example, the patent application number 201821070687.6 discloses a cable stripping device for power maintenance, which solves the problem that manual cable stripping is prone to danger and accidental finger injury. However, it has problems such as low automation, inability to strip multiple power cables at the same time, poor cable stripping quality, and limited applicability.

[0004] Based on this, the applicant proposes an automatic stripping device for power cables. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of existing cable stripping devices, such as low automation, inability to strip multiple power cables at the same time, poor cable stripping quality, and limited applicability. This invention provides an automatic cable stripping device with a reasonable structural design, high automation, the ability to strip multiple power cables at the same time, good cable stripping quality, and wide applicability.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0007] An automatic stripping device for power cables includes a base plate, a bearing shaft, and pressure rollers. The base plate has upright plates with bearings on them. A top plate is located on top of the upright plates. A winding structure is positioned between the upright plates, and a pushing structure is located on the top plate. The winding structure pulls the stripped power cable core and outer sheath, winding them up for easier sorting and reducing resource waste. The bearing shaft has bearings inserted at both ends and bearing rollers with blades mounted on them. The pressure rollers are positioned at... The rotating shaft has blades mounted on the pressure rollers, and is positioned on a pushing structure. The power cable requiring stripping is placed on the carrying roller, where the blades strip the cable from the bottom. The pressure roller moves downwards under the action of the pushing structure, and its blades strip the cable from the top. A winding structure pulls the stripped cable core and outer sheath, and then pulls the unstripped cable forward between the carrying rollers and pressure rollers for further stripping. This system achieves automatic stripping of power cables, improving stripping efficiency and reducing the workload of operators.

[0008] Preferably, the winding structure includes a motor and a winding shaft. The motor is mounted on a vertical plate and has a drive shaft. One end of the drive shaft is inserted into a bearing, and a drive wheel is mounted on the drive shaft. The winding shaft is located on the upper and lower sides of the drive shaft, with both ends inserted into bearings. Driven wheels are mounted on the drive shaft and connected to the drive wheel via belts. The motor drives the drive shaft and the drive wheel to rotate, and the drive wheel drives the winding shaft to rotate via belts. The winding shaft winds up the outer sheath of the power cable after it has been stripped by the blades on the bearing wheel and the pressure wheel. It then pulls the unstripped power cable forward into the space between the bearing wheel and the pressure wheel for further stripping. This achieves automatic stripping of the power cable, reducing the labor intensity of the operators.

[0009] Preferably, the drive shaft is equipped with drive wheels, and the drive wheels and bearing wheels are configured to correspond one-to-one. After the outer sheath of the power cable is stripped by the blades on the bearing wheels and the blades on the pressure wheels, it is wound up by the winding shaft. The stripped power cable core continues to be transported forward on the drive wheels, which facilitates subsequent processing of the power cable core. By configuring the drive wheels and bearing wheels to correspond one-to-one and configuring multiple bearing wheels on the bearing shaft, multiple power cables can be stripped at the same time, thereby improving the stripping efficiency of the power cables.

[0010] Preferably, the pushing structure includes a hydraulic cylinder and a connecting plate. The hydraulic cylinder is mounted on the top plate and has a piston rod. The connecting plate is connected to the piston rod, and a fixing plate is mounted on the connecting plate. A second bearing is mounted on the fixing plate. Both ends of the rotating shaft are inserted into the second bearing. Under the action of the hydraulic cylinder, the connecting plate moves downward, causing the rotating shaft and the pressure roller on the rotating shaft to descend. The pressure roller presses down on the power cable. The blades on the pressure roller strip the power cable from above, and the blades on the bearing roller strip the power cable from below. This allows for rapid stripping of the power cable. By adjusting the position of the pressure roller, the pressure force of the pressure roller on the power cable can be adjusted, thereby adjusting the stripping depth of the power cable sheath by the blades on the bearing roller and the pressure roller. This avoids damage to the power cable core, improves the stripping quality of the power cable, and also improves the integrity of the power cable core.

[0011] Preferably, the pressure roller and the bearing roller are configured in a one-to-one correspondence structure, with both the pressure roller and the bearing roller being replaceable on the rotating shaft. The power cable requiring stripping moves forward between the bearing roller and the pressure roller, and the blades on the bearing roller strip the cable from below, enabling rapid stripping. Multiple bearing rollers are mounted on the bearing shaft, and multiple pressure rollers are mounted on the rotating shaft, allowing for simultaneous stripping of multiple power cables, thus improving stripping efficiency. Depending on the size of the power cable, a suitable pressure roller can be selected. The corresponding blades on the bearing wheel and pressure wheel enable the blades on the bearing wheel and pressure wheel to perform precise stripping of power cables, and also make the automatic stripping device applicable to different power cables, thus expanding the application range of the automatic stripping device and reducing the cost of manufacturing multiple sets of automatic stripping devices. In order to facilitate quick replacement of the bearing wheel on the bearing shaft or the pressure wheel on the rotating shaft, nuts can be set on the bearing shaft on both sides of the bearing wheel to fix the bearing wheel, and nuts can be set on the rotating shaft on both sides of the pressure wheel to fix the pressure wheel. This not only improves the stability of the bearing wheel on the bearing shaft and the pressure wheel on the rotating shaft, but also facilitates the quick replacement of the bearing wheel or pressure wheel.

[0012] Beneficial effects:

[0013] 1. The power cable requiring stripping is placed on the carrying wheel. The blades on the carrying wheel strip the cable from the bottom. The pressure wheel moves downward under the action of the pushing structure, and the blades on the pressure wheel strip the cable from the top. The winding structure pulls the stripped cable core and outer sheath, and pulls the unstripped cable forward to enter between the carrying wheel and the pressure wheel for stripping. This achieves automatic stripping of power cables, improves the stripping efficiency of power cables, and reduces the labor intensity of operators.

[0014] 2. Multiple bearing rollers are installed on the bearing shaft, and multiple pressure rollers are installed on the rotating shaft. This allows for the simultaneous stripping of multiple power cables, thereby improving the stripping efficiency. Depending on the size of the power cable, bearing rollers and pressure rollers with appropriate blades are selected. This ensures that the blades on the bearing rollers and pressure rollers can precisely strip the power cable, and also makes the automatic stripping device applicable to different power cables. This expands the applicability of the automatic stripping device and reduces the cost of manufacturing multiple sets of automatic stripping devices. Attached Figure Description

[0021] The present invention will now be described in more detail with reference to the accompanying drawings.

[0022] Example 1:

[0023] As attached Figure 1-4As shown, an automatic stripping device for power cables includes a base plate 1, a bearing shaft 2, and a pressure roller 3. A vertical plate 4 is provided on the base plate 1, a bearing 6 is provided on the vertical plate 4, a top plate 5 is provided on the top of the vertical plate 4, a winding structure is provided between the vertical plates 4, and a pushing structure is provided on the top plate 5. Both ends of the bearing shaft 2 are inserted into the bearing 6, a bearing roller 14 is provided on the bearing shaft 2, and a blade 15 is provided on the bearing roller 14. The pressure roller 3 is provided on a rotating shaft 18, the blade 15 is provided on the pressure roller 3, and the rotating shaft 18 is provided on the pushing structure.

[0024] The winding structure includes a motor 7 and a winding shaft 8. The motor 7 is mounted on the vertical plate 4, and a drive shaft 9 is mounted on the motor 7. One end of the drive shaft 9 is inserted into a bearing 6, and a drive wheel 10 is mounted on the drive shaft 9. The winding shaft 8 is mounted on the upper and lower sides of the drive shaft 9, and both ends of the drive shaft 9 are inserted into bearings 6. A driven wheel 12 is mounted on the drive shaft 9, and the driven wheel 12 is connected to the drive wheel 10 via a belt 13. A drive wheel 11 is mounted on the drive shaft 9, and the drive wheel 11 and the bearing wheel 14 are configured to correspond one-to-one.

[0025] The pushing structure includes a hydraulic cylinder 16 and a connecting plate 17. The hydraulic cylinder 16 is mounted on the top plate 5. A piston rod 19 is mounted on the hydraulic cylinder 16. The connecting plate 17 is connected to the piston rod 19. A fixing plate 20 is mounted on the connecting plate 17. A bearing 21 is mounted on the fixing plate 20. Both ends of the rotating shaft 18 are inserted into the bearing 21.

[0026] The pressure roller 3 and the bearing roller 14 are configured to correspond one-to-one. The pressure roller 3 is configured to be replaceable on the rotating shaft 18, and the bearing roller 14 is configured to be replaceable on the bearing shaft 2.

[0027] Example 2:

[0028] Further explanation is provided based on Example 1, as shown in the appendix. Figure 5As shown, an automatic stripping device for power cables has a limit rod 22 on a top plate 5 and a limit ring 23 on a connecting plate 17. The limit rod 22 is vertically inserted into the limit ring 23. The power cable to be stripped moves forward between the bearing wheel 14 and the pressure wheel 3. The connecting plate 17 moves downward under the action of the hydraulic cylinder 16, causing the rotating shaft 18 and the pressure wheel 3 on the rotating shaft 18 to descend. The pressure wheel 3 presses down on the power cable, and the blade 15 on the pressure wheel 3 strips the cable from above. The blade 15 on the bearing wheel 14 strips the cable from below, dividing the outer sheath of the power cable into left and right halves. The cable core continues to move forward on the drive wheel 11. The outer sheaths of the power cable on both sides pass through the drive shaft 9 and are wound onto the take-up shaft 8 to perform the take-up process. The unstripped power cable is pulled forward to perform the stripping process. During the vertical adjustment of the connecting plate 17, the limiting ring 23 moves vertically along the limiting rod 22, so that the limiting rod 22 and the limiting ring 23 can limit the vertical adjustment of the connecting plate 17, preventing the pressure roller 3 from shaking during the stripping process of the power cable. This improves the stripping efficiency and stripping effect of the power cable, facilitates the classification and processing of the stripped power cable, and reduces the waste of resources.

[0029] Working principle: Based on the different sizes of power cables, select a bearing wheel 14 and a pressure wheel 3 with corresponding blades 15. Mount the bearing wheel 14 on the bearing shaft 2 and the pressure wheel 3 on the rotating shaft 18, aligning the pressure wheel 3 and bearing wheel 14 vertically. Place the power cable requiring stripping on the bearing wheel 14. Activate the hydraulic cylinder 16, causing the connecting plate 17 to move downwards, which in turn lowers the rotating shaft 18 and the pressure wheel 3 on it. This causes the pressure wheel 3 to press down on the power cable, and the blades 15 on the pressure wheel 3 strip the cable from above. The blades 15 on the bearing wheel 14 strip the cable from below, thus stripping the cable... The outer sheath is divided into left and right halves. The power cable core continues to move forward on the drive wheel 11. The outer sheaths of the left and right halves of the power cable pass through the drive shaft 9 and are wound on the take-up shaft 8. The motor 7 is started, and the motor 7 drives the drive shaft 9 and the drive wheel 10 on the drive shaft 9 to rotate. The drive wheel 10 drives the take-up shaft 8 to rotate through the belt 13. The take-up shaft 8 performs the take-up process on the outer sheath of the power cable after it has been stripped by the blades 15 on the bearing wheel 14 and the pressure wheel 3. The stripped power cable core continues to be transmitted forward on the drive wheel 11, pulling the unstripped power cable to continue moving forward into the space between the bearing wheel 14 and the pressure wheel 3 for stripping, thus realizing the automatic stripping of the power cable.
