Description

Technical Field

[0001] This utility model relates to the field of wire stripping technology, and in particular to an auxiliary device for wire stripping. Background Technology

[0002] An automatic wire stripping machine is a device for stripping the insulation of wires. It consists of a motor and a cutter, and has a good stripping effect with low power consumption, making it widely used in various fields. However, existing automatic wire stripping machines have certain drawbacks. They cannot heat and soften the outer sheath of the wire during use, which affects the stripping effect in cold winters. For example, low temperatures make the outer sheath of the wire hard and brittle, making it difficult to bend and easy to break during stripping. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of poor wire stripping performance in cold weather by proposing an auxiliary device for wire stripping.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An auxiliary device for stripping wire insulation is provided. The auxiliary device is located upstream of the stripping machine station. The auxiliary device includes two sets of friction mechanisms distributed vertically. Each friction mechanism includes a first friction component on the upper side and a second friction component on the lower side. The first friction component includes a first friction element, and the second friction component includes a second friction element. The wire is clamped between the first friction element and the second friction element, and the first friction element and the second friction element can generate sliding friction on the wire during operation.

[0006] The first friction element and the second friction element are industrial rubber strips or polyurethane strips fixedly mounted on the bracket.

[0007] The second friction assembly includes two second support shafts rotatably connected to the bracket, each second support shaft having a second pulley fixedly connected to it, and the second friction element being an annular friction belt installed between the two second pulleys, with one of the second support shafts being drive-connected to a rotary motor.

[0008] The first friction assembly includes two first support shafts, with sliders rotatably connected to both ends of the first support shafts. The bracket is provided with a slide rail that is slidably connected to the sliders. A thrust spring that can cause the first support shaft to move closer to the second support shaft is installed between the slider and the bracket. A first pulley is fixedly connected to the first support shaft. The first friction element is an annular friction belt installed between the two first pulleys. The first support shaft is drive-connected to the second support shaft.

[0009] A first drive wheel is fixedly connected to the first support shaft, and a second drive wheel is fixedly connected to the second support shaft. The second drive wheel and the first drive wheel are connected by a drive belt, and a tensioning wheel is installed between the drive belt and the bracket.

[0010] The adjacent sides of the first and second friction components are opposite to the direction of the wire's movement.

[0011] The first friction element and the second friction element have the same structure. The first friction element includes an annular belt, a first Velcro fastener fixed to the annular belt, and a friction strip bonded to the first Velcro fastener by a second Velcro fastener.

[0012] The present invention proposes an auxiliary device for stripping the insulation of electrical wires. The beneficial effect is that when stripping the insulation of electrical wires, the wires pass between the first friction element and the second friction element and are then fed into the stripping machine. During the process of the stripping machine pulling the wires to strip the insulation, the wires generate sliding friction with the first and second friction elements. The principle of frictional heat generation is used to heat and soften the outer insulation of the wires. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-3An auxiliary device for stripping wire insulation is provided. The auxiliary device is located upstream of the stripping machine station. The auxiliary device includes two sets of friction mechanisms distributed vertically. The friction mechanism includes a first friction component 1 on the upper side and a second friction component 11 on the lower side. The first friction component 1 includes a first friction element 6, and the second friction component 11 includes a second friction element 9. The wire is clamped between the first friction element 6 and the second friction element 9, and the first friction element 6 and the second friction element 9 can generate sliding friction on the wire during operation.

[0019] refer to Figure 1 When stripping the wire, the wire is passed between the first friction element 6 and the second friction element 9 and then fed into the stripping machine. During the process of the stripping machine pulling the wire to strip the wire, the wire generates sliding friction with the first friction element 6 and the second friction element 9. The principle of friction heat generation is used to heat and soften the outer sheath of the wire.

[0020] In one implementation, the first friction element 6 and the second friction element 9 are industrial rubber strips or polyurethane strips fixedly mounted on the bracket 7. Because these two materials have a high coefficient of friction, they can generate significant frictional heat in a short time and possess a certain degree of elasticity, reducing damage to the wire sheath during preheating. By setting strips of different lengths, the desired softening effect can be flexibly configured, and the cost is low, with simple replacement requiring only periodic strip replacement.

[0021] In another embodiment, the second friction assembly 11 includes two second support shafts 13 rotatably connected to the bracket 7. Each second support shaft 13 has a second pulley 10 fixedly connected to it. The second friction element 9 is an annular friction belt mounted between the two second pulleys 10. One of the second support shafts 13 is drive-connected to a rotary motor. The rotary motor drives the second support shafts 13 to rotate, causing the annular friction belt to rotate in the opposite direction to the direction of the wire's movement, thereby increasing the frictional heat output. By adjusting the rotational speed of the rotary motor, the required frictional heat can be obtained without the need for an excessively long friction belt.

[0022] Furthermore, the first friction assembly 1 includes two first support shafts 5, with sliders 2 rotatably connected to both ends of the first support shafts 5. The bracket 7 is provided with a slide rail 4 that is slidably connected to the sliders 2. A thrust spring 3 that can cause the first support shaft 5 to move closer to the second support shaft 13 is installed between the slider 2 and the bracket 7. A first pulley 8 is fixedly connected to the first support shaft 5. The first friction element 6 is an annular friction belt installed between the two first pulleys 8. The first support shaft 5 and the second support shaft 13 are connected in a transmission manner.

[0023] The first friction element 6 and the second friction element 9 are adjacent to each other and move in opposite directions to the wire. By rubbing the wire simultaneously with the first friction element 6 and the second friction element 9 which are distributed vertically, the frictional heat is increased. The first support shaft 5 of this device can generate an elastic force that moves in the direction of the second support shaft 13, which can better clamp the wire.

[0024] As a transmission method, a first transmission wheel 12 is fixedly connected to the first support shaft 5, and a second transmission wheel 14 is fixedly connected to the second support shaft 13. The second transmission wheel 14 and the first transmission wheel 12 are connected by a transmission belt, and a tensioning wheel 15 is installed between the transmission belt and the bracket 7. The tensioning wheel 15 tensions the transmission belt, facilitating the elastic up-and-down movement of the first support shaft 5.

[0025] For easy replacement of friction components, refer to Figure 3 As shown, the first friction element 6 and the second friction element 9 have the same structure. The first friction element 6 includes an annular belt 16, a first hook and loop fastener 17 fixed to the annular belt 16, and a friction band 18 bonded to the first hook and loop fastener 17 by a second hook and loop fastener. After prolonged use, the friction band 18 will wear out. Simply peel the worn friction band 18 off the first hook and loop fastener 17 and replace it with a new friction band 18 with a second hook and loop fastener.

[0026] This device achieves preheating and softening by directly rubbing the wire sheath with a friction element, which is inexpensive and has a simple structure.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
