TECHNICAL FIELD
[0001] The present application relates to the technical field of mining cable processing, in particular to a mining cable processing and manufacturing device with continuity. BACKGROUND
[0002] Mining cable processing involves multiple steps, including but not limited to cutting, stripping, joint making, and insulation treatment, etc., among which the key step is to heat and extrude thermoplastic materials (such as cross-linked polyethylene) to form the insulation layer or sheath of the cable. Typically, the copper conductor is continuously fed through the center channel of the extruder and passes through a special component called "die head". The thermoplastic material is extruded under high temperature and pressure and wrapped around the copper conductor through the die head, thereby forming the required insulation layer or protective sheath. However, during long-term continuous operation, especially during peak electricity consumption, the extrusion speed may vary due to unstable power supply, resulting in uneven thickness of the insulation layer or sheath in some areas of the cable, which affects the quality of the mining cable.
[0003] For example, the processing device for rubber sheath of mining cable disclosed in the publication No. CN105047328B can perform continuous operation of mining cable, but it cannot adjust in time when the extrusion speed changes, resulting in uneven thickness of the insulation layer or sheath in some areas of the cable, which affects the quality of the mining cable. The wire extruder line speed control system and method disclosed in the publication No. CN109616258A can adaptively control the extrusion speed according to the size of the processed cable, but it still cannot avoid the problem of uneven thickness of the insulation layer or sheath in some areas of the cable caused by the change of the flow speed of the thermoplastic material due to unstable power supply.

[0054] The side wall of the sliding plate 312 slides against the side wall of the expansion block 311, the bottom of the guide block 314 is fixedly installed on the inner wall bottom of the adjusting block 32, the bottom of the sliding plate 312 slides through the guide block 314, the guide block 314 is used for limiting the moving direction of the sliding plate 312, one end of the spring three 313 is fixedly installed on the side wall of the sliding plate 312, the other end of the spring three 313 is fixedly installed in the guide block 314, and the spring three 313 is used for providing elastic force for resetting the sliding plate 312.
[0055] In use, when the control switch 29 is started, the compensation motor 3 is started, the rotating shaft 31 is driven to rotate through the compensation motor 3, the adjusting block 32 is driven to rotate by the rotating shaft 31, the adjusting block 32 is rotated from the shell 11 into the inner cavity, so that the thermoplastic material in the inner cavity is extruded, so that the molten thermoplastic material can flow from the inner cavity to the die, so that when the driving is lost, the thermoplastic material does not appear stagnant, and the uniformity of the copper wire 12 outside the insulating layer is affected;
[0056] Further, when the adjusting block 32 rotates under the driving of the compensation motor 3, the adjusting block 32 drives the upper sliding block 35 to rotate synchronously, the upper sliding block 35 and the lower sliding block 36 slide against each other to extrude the lower sliding block 36 to move, and the lower sliding block 36 and the guide column 37 slide against each other, the adjusting block 32 provides support force for the guide column 37, so that the lower sliding block 36 can move linearly along the guide column 37 under the extrusion of the upper sliding block 35, the lower sliding block 36 moves linearly downward, so that the air bag 39 is deformed, the gas in the air bag 39 is transported to the expansion block 311 through the air pipe 310, the sliding plate 312 is extruded to move after the expansion block 311 is expanded, so that the sliding plate 312 can move away from the side where the expansion block 311 is located under the extrusion of the expansion block 311, the sliding plate 312 and the guide block 314 slide against each other, so that the sliding plate 312 can only move linearly along the guide block 314 under the extrusion of the expansion block 311, the extrusion block 34 is pushed by the sliding plate 312, so that the extrusion block 34 extrudes the deformation surface of the adjusting block 32, so that the deformation surface protrudes from the adjusting block 32, so that the shape of the adjusting block 32 is changed, so that the adjusting block 32 can still fit the circular arc space in the inner cavity of the shell 11 after rotating, so that the thermoplastic material in the inner cavity cannot enter the circular arc space originally occupied by the adjusting block 32 in a large amount, so that although the adjusting block 32 protrudes from the circular arc space into the inner cavity of the shell 11, the extrusion force generated by occupying the inner cavity space compensates for the driving loss of the thermoplastic material, but the vacancy of the circular arc space provides excess space for the thermoplastic material to unload, so that the compensation effect is poor or useless;

When the temperature is too high and the flowability of the material increases, the compensation motor 3 is started to rotate counterclockwise, so that the adjusting block 32 on the right side of the middle part rotates counterclockwise to extend from the circular arc space, and the adjusting block 32 on the left side of the middle part rotates clockwise to extend from the circular arc space, thereby increasing the flow resistance of the thermoplastic material. Figure 14 Figure 14 When the temperature is too low and the flowability of the material decreases, the compensation motor 3 is started to rotate clockwise, so that the adjusting block 32 on the right side of the middle part rotates clockwise to extend from the circular arc space, and the adjusting block 32 on the left side of the middle part rotates counterclockwise to extend from the circular arc space, thereby increasing the flow power of the thermoplastic material. Figure 14 Figure 14 When the temperature is too low and the flowability of the material decreases, the compensation motor 3 is started to rotate clockwise, so that the adjusting block 32 on the right side of the middle part rotates clockwise to extend from the circular arc space, and the adjusting block 32 on the left side of the middle part rotates counterclockwise to extend from the circular arc space, thereby increasing the flow power of the thermoplastic material.
[0059] In another embodiment different from the foregoing embodiments, the number of compensation motors 3 in the shell 11 is changed to one, and another rotating shaft 31 is driven to rotate by a gear or other transmission mode, and the rotation modes of the two rotating shafts 31 are opposite.
