Description

Technical Field

[0001] This utility model relates to the technical field of cable stripping and recycling devices, and in particular to a cable insulation stripping machine. Background Technology

[0002] In the recycling of discarded cables, the outer insulation layer of the new cable is usually cut along the axial direction to separate the insulation layer and the wire core inside, so that the insulation layer and the wire core can be remelted and recycled separately.

[0003] However, in existing recycling operations, the insulation layer is directly separated using a blade. Since the insulation layer has a certain degree of hardness, it causes significant wear on the blade, resulting in a shorter blade lifespan. This, to some extent, increases the cost of cable insulation stripping operations. Utility Model Content

[0004] In view of the above problems, this utility model provides a cable insulation stripping machine, the purpose of which is to reduce tool wear and extend tool life.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A cable insulation stripping machine is provided, comprising: several pairs of rotatably mounted first and second rollers, which respectively roll and press against both sides of the cable and guide the cable to move on a first horizontal plane at a horizontal height of h1; several pairs of rotatably mounted third and fourth rollers, which respectively roll and press against both sides of the cable and guide the cable to move on a second horizontal plane at a horizontal height of h2; wherein, in the vertical direction, h1 > h2, thereby forming a U-shaped cable transport path; a water tank, which stores water at a horizontal height of h3, with the third and fourth rollers located inside the water tank, and h1 > h3 > h2, thereby submerging the cable; a heating element, disposed inside the water tank, used to heat the water in the tank to soften the cable insulation layer; and a pair of cutting blades, symmetrically disposed on both sides of the first horizontal plane, used to cut the cable insulation layer.

[0007] Furthermore, the stripping machine also includes: a lifting plate, on which a water tank is mounted; and a scissor lift for driving the lifting plate to move vertically up and down, thereby moving the water tank closer to / away from the cable.

[0008] Furthermore, the peeling machine also includes: a water level detection component, installed inside the water tank, for detecting the water level height; and a water pump, the outlet of which is connected to the inside of the water tank for replenishing water into the tank.

[0009] Furthermore, the peeling machine also includes: a first cover plate and a second cover plate, both of which are rotatably mounted on the water tank via hinges for sealing the water tank; the first cover plate and the second cover plate are also provided with semi-circular through holes for cables to pass through.

[0010] Furthermore, the peeling machine also includes: a vertically mounted first telescopic component, and a second roller rotatably mounted on the piston rod of the first telescopic component. The piston rod of the first telescopic component performs telescopic movements, which can drive the second roller to move closer to / away from the first roller.

[0011] Furthermore, the heating element is a resistance wire, which is located at the bottom of the water tank.

[0012] The beneficial effects of this utility model are as follows: In this utility model, by heating and softening the insulation layer of the cable before cutting the insulation layer, the wear of the cutting blade can be effectively reduced, the service life of the cutting blade can be extended, thereby reducing the cost of cable insulation stripping operations.

Detailed Implementation

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0018] Reference Figure 1As shown in the embodiment of this application, a cable insulation stripping machine is disclosed, comprising: several pairs of rotatably mounted first rollers 11 and second rollers 12, which respectively roll and press against both sides of the cable and guide the cable to move on a first horizontal plane with a horizontal height of h1; several pairs of rotatably mounted third rollers 13 and fourth rollers 14, which respectively roll and press against both sides of the cable and guide the cable to move on a second horizontal plane with a horizontal height of h2; wherein, in the vertical direction, h1 > h2, thereby forming a U-shaped cable transport path; a water tank 2, which is filled with water, with the water level at a horizontal height of h3, and the third rollers 13 and fourth rollers 14 are located in the water tank 2, with h1 > h3 > h2, thereby submerging the cable; a heating component 3, which is disposed in the water tank 2, for heating the water in the water tank 2, thereby softening the insulation layer of the cable; and a pair of cutting blades 4, which are symmetrically disposed on both sides of the first horizontal plane, for cutting the insulation layer of the cable.

[0019] In this invention, a water tank 2 is installed along the cable transport path. The water tank 2 contains water sufficient to submerge the cable. During transport, the cable can remain in the water for a certain period of time. By heating the water in the water tank 2, the insulation layer of the cable can be heated and softened. Then, the insulation layer of the cable can be cut open by the cutting blade 4. By using this invention, the insulation layer of the cable can be heated and softened, which facilitates the subsequent stripping work of the cutting blade 4, reduces the wear of the cutting blade 4, extends the service life of the cutting blade 4, and thus reduces the cost of stripping the cable insulation layer.

[0020] Specifically, the stripping machine also includes: a lifting plate 5, on which a water tank 2 is mounted; and a scissor lift 51, which drives the lifting plate 5 to move vertically, thereby moving the water tank 2 closer to / away from the cable. In this embodiment, by driving the lifting plate 5 to move through the scissor lift 51, the water tank 2 can be moved away from the cable, making it easier for workers to pass the end of the cable to be stripped between the third roller 13 and the fourth roller 14.

[0021] In this embodiment, the peeling machine further includes: a water level detection component 61, which may be an infrared water level sensor, installed inside the water tank 2, for detecting the water level height; and a water pump 62, the outlet of which is connected to the inside of the water tank 2, for replenishing water into the water tank 2; the water level detection component 61 and the water pump 62 can be electrically connected by a PLC controller, and when the water level in the water tank 2 is lower than the value set in the water level detection component 61, the water pump 62 is started to replenish water into the water tank 2 to ensure that the cable is submerged.

[0022] Reference Figure 2 and Figure 3As shown, the peeling machine also includes: a first cover plate 21 and a second cover plate 22, both of which are rotatably mounted on the water tank 2 via hinges for sealing the water tank 2; the first cover plate 21 and the second cover plate 22 are also provided with semi-circular through holes for cables to pass through, and by rotating the first cover plate and the second cover plate 22, the water tank 2 can be sealed, reducing heat loss.

[0023] Specifically, the peeling machine also includes: a vertically installed first telescopic component 71, and a second roller 12 rotatably mounted on the piston rod of the first telescopic component 71. The piston rod of the first telescopic component 71 performs telescopic movements, which can drive the second roller 12 to move closer to / away from the first roller 11. By activating the extension of the telescopic component of the first telescopic component 71, the second roller 12 can be driven closer to the first roller 11 to tighten the cable.

[0024] It is worth mentioning that a servo motor is also provided in this embodiment. The output shaft of the servo motor is connected to the first roller 11 through a coupling. The output shaft of the servo motor drives the first roller 11 to rotate, which in turn drives the cable to be transported along the transport path.

[0025] Reference Figure 4 As shown, in this embodiment, a second telescopic component 72 is also provided. The second telescopic component 72 is installed in the vertical direction, and the cutting blade 4 is disposed on the piston rod of the second telescopic component 72. By the telescopic movement of the piston rod of the second telescopic component 72, the cutting blade 4 can be driven to extend into the insulation layer to different depths and cut the insulation layer of different thicknesses.

[0026] It is worth mentioning that the first telescopic component 71 can be either a hydraulic cylinder or an electric telescopic rod.

[0027] In this embodiment, the heating element 3 is a resistance wire, which is located at the bottom of the water tank 2. By supplying power to the resistance wire, the water in the water tank 2 can be heated.
