Description

Technical Field

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

[0002] Power conductors are essential components in power systems used to transmit electrical energy, typically consisting of conductors and insulation layers. They establish electrical connections between various electrical devices and the power grid, ensuring a stable supply of electrical power.

[0003] During the installation, repair, or replacement of electrical conductors, it is often necessary to strip the wires. Stripping involves removing the insulation layer from the ends of the wires to expose the inner conductor, facilitating connection to terminals, sockets, or other electrical equipment. This step is crucial for ensuring the reliability and safety of electrical connections.

[0004] However, existing power conductor stripping technologies have some drawbacks. For example, many stripping tools or equipment cannot automatically cut the insulation layer after stripping, requiring manual follow-up processing. This not only increases operational complexity but may also affect the efficiency and accuracy of stripping. Furthermore, some stripping equipment is inadequate in terms of ease of operation and stripping quality, failing to meet the demands of modern power systems for efficient, safe, and reliable stripping.

[0005] Therefore, we propose an automatic wire stripping device for power conductors. Utility Model Content

[0006] The purpose of this invention is to provide an automatic wire stripping device for power conductors to address the aforementioned shortcomings in the prior art.

[0008] A feed roller assembly is rotatably mounted on the housing via a universal joint, and a pull rod is slidably mounted on the housing. A separation mechanism is provided between the pull rod and the feed rollers. When the pull rod is pulled and displaced, the feed roller assembly is separated from each other by the separation mechanism.

[0009] Two sets of cutting blades are mounted on the separation mechanism via a drive mechanism. When the feed rollers separate, the two cutting blades move closer to each other to cut the outer sheath of the wire.

A synchronous belt is installed between one of the gears in the gear set and the lead screw via a synchronous pulley. The rack meshes with one of the gears in the gear set. A connecting rod is threaded onto the lead screw, and a sliding seat is provided on the connecting rod that slides on the housing. The end of the feed roller set away from the universal joint is fixedly connected to the sliding seat.

[0013] As a further description of the above technical solution: the housing is also provided with an inclined surface, and the inclined surface abuts against the surface of the sliding seat.

[0015] In the above technical solution, the automatic wire stripping device for power conductors provided by this utility model has the following beneficial effects:

[0016] 0. This device automatically inserts the wire into the through hole of the housing through the feeding roller group and abuts against the wire stripper to realize automatic wire stripping.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 This utility model provides a technical solution: an automatic wire stripping device for power conductors, including a housing 1 with a through hole and multiple sets of wire stripping blades 3 arranged in a circumferential array on the through hole of the housing 1. When it is necessary to strip the wire, the wire is passed through the through hole of the housing 1, and the wire stripping can be achieved by the multiple sets of wire stripping blades 3. The wire stripping blades 3 are inclined along the feed roller group 2 to the housing 1 towards the axis of the through hole of the housing 1. The inclined wire stripping blades 3 provide a certain buffer when the wire is inserted, which can effectively reduce the difficulty of stripping the wire.

[0027] In order to automatically feed the conductors, the automatic wire stripping device for power conductors also includes:

[0028] The feeding roller assembly 2 is rotatably mounted on the housing 1 via a universal joint. By inserting the wire into the gap between the feeding roller assemblies 2, the feeding roller assembly 2 can be started to achieve automatic feeding of the wire. The surface of the feeding roller assembly 2 is provided with multiple sets of protrusions to increase friction with the wire and prevent slippage. The feeding roller assembly 2 automatically inserts the wire into the through hole of the housing 1 and abuts against the wire stripper 3, thereby achieving automatic wire stripping.

[0029] After stripping the wire to a suitable length, the pull rod 8, which is slidably mounted on the housing 1, is used to separate the feed rollers. A separation mechanism is provided between the pull rod 8 and the feed rollers. When the pull rod 8 is pulled and displaced, the feed roller group 2 is separated from each other by the separation mechanism. At this time, the feed roller group 2 is separated from each other, and the gap increases. The feed roller group 2 is separated from the wire or slips due to reduced friction caused by the separation. At this time, the wire is no longer fed and the stripping stops. The stripping can be stopped with one click by pulling the pull rod 8 while the wire is being automatically fed and stripped, which is quite convenient to operate.

[0030] In one embodiment of this utility model, the separating mechanism includes a gear set 7 and a lead screw 4 rotatably mounted on the housing 1, and a rack 6 slidably mounted on the housing 1 and fixedly connected to a pull rod 8. When the pull rod 8 is pulled, the rack 6 moves with the pull rod 8, thereby driving the gear set 7 to rotate. A synchronous belt 5 is installed between one of the gears in the gear set 7 and the lead screw 4 via a synchronous pulley. The rack 6 meshes with one of the gears in the gear set 7. A connecting rod 9 is threaded onto the lead screw 4, and a sliding seat 1 that slides on the housing 1 is provided on the connecting rod 9. 4. The end of the feed roller assembly 2 away from the universal joint is fixedly connected to the sliding seat 14. When the gear set 7 rotates, the screw 4 is driven to rotate by the synchronous belt 5, thereby causing the connecting rod 9 to move on the screw 4. At this time, the feed roller assembly 2 is driven to move away from the housing 1 by the sliding seat 14. Since the housing 1 is also provided with an inclined surface 13, and the inclined surface 13 abuts against the surface of the sliding seat 14, when the feed roller assembly 2 moves away from the housing 1, the sliding seats 14 will move away from each other through the inclined surface 13, thereby causing the feed roller assembly 2 to move away from each other, thus separating from the wire and stopping the feeding.

[0031] After the feeding stops, the two sets of cutting heads 12, which are installed on the separation mechanism by the drive mechanism, move closer to each other when the feeding roller group 2 separates to cut the outer sheath of the wire. At this time, the feeding action can be stopped automatically after the wire is stripped to a suitable length, and the stripped sheath can be cut automatically without manual stripping.

[0032] In another embodiment of this utility model, the driving mechanism includes a gear disk 10 rotatably mounted on the housing 1 and connected to the rotation axis of one of the gears in the gear set 7. Two sliding blocks 11 are slidably arranged on both sides of the gear disk 10 in the housing 1. The side of the sliding block 11 closer to the gear disk 10 engages with the gear disk 10 through teeth, while the side away from the gear disk 10 is equipped with the cutting blade 12. When the gear set 7 rotates, one of the gears drives the gear disk 10 to rotate, thereby bringing the two sliding blocks 11 closer to each other, and thus bringing the two cutting blades 12 closer to each other until the outer sheath of the wire is clamped off, thus achieving the cutting of the outer sheath of the stripped wire without the need for manual stripping, greatly improving the convenience of operation. After the cutting is completed, the wire is pulled out from the through hole of the housing 1, thus completing the entire stripping process.

[0033] It should be noted that the reason for using gear set 7 is to bring the cutting blades 12 closer together rather than separate them when pulling the pull rod 8. Using gear set 7 makes it easier for the user to hold the blade.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
