Description

Technical Field

[0001] The present invention belongs to the technical field of cable production, and particularly relates to a cable and its production device. Background Art

[0002] During the current cable coating process, generally, a polyethylene layer in a molten state is placed in an extruder. Through the extrusion of the extruder, the molten polyethylene layer is extruded into the wire core inlet. By pulling the wire core with an external force, the molten polyethylene layer will be pulled in the advancing direction of the wire core, so as to realize the coating of the polyethylene molten liquid on the surface of the wire core in a pulled state.

[0003] However, when the cable is only coated with a polyethylene layer, the resulting cable product has relatively high heat insulation performance, which will cause the cable to be unable to work for a long time under the sun exposure; at the same time, during the production process of the cable, it is necessary to detect the resistance performance of the cable. Currently, when detecting the resistance performance of the cable, most of the time, workers manually connect the cut cable to the resistance detection device. Both the connection and disconnection of the cable and the resistance detection device require manual operation. When manually operating, the bolts used for pressing at the connection between the cable and the resistance detection device need to be loosened, and then the cable and the resistance detection device are separated. The steps required for manually separating and connecting the cable and the resistance detection device are numerous, resulting in low efficiency of cable resistance detection; therefore, the present application proposes a cable and its production device. Summary of the Invention

The lower clamping plate and the upper clamping plate are respectively located on the upper and lower sides of the cable.

[0028] The following is a detailed description of the specific embodiments of the present invention, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0029] As Figures 1-6 shown, a cable and its production device provided by an embodiment of the present invention include a detection table 1 and a resistance detection device 7. A line connection power mechanism 2, a moving plate 3, and a cable storage plate 4 are arranged on the upper side of the detection table 1. A conductive joint 5 is installed on the moving plate 3. A storage groove for storing the cable 6 is arranged in the cable storage plate 4. The conductive joint 5 is connected to the resistance detection device 7. The line connection power mechanism 2 is connected to the moving plate 3. The line connection power mechanism 2 is used to drive the moving plate 3 to move, so that the moving plate 3 approaches or moves away from the cable storage plate 4. When the moving plate 3 approaches the cable storage plate 4, the conductive joint 5 on the moving plate 3 is connected to the cable 6 on the cable storage plate 4. The conductive joint 5 is connected to the resistance detection device 7. When the two conductive joints 5 on the two moving plates 3 are respectively connected to both ends of the cable 6, a closed loop can be formed. This closed loop can measure the resistance of the cable 6. By detecting the resistance value of the cable 6, it is judged whether the resistance value of the cable 6 meets the designed index.

[0030] It should be noted that the conductive joint 5 includes a working surface and an insulating area. One end of the conductive joint 5 close to the cable storage plate 4 is the working surface. The insulating area is arranged on the part of the conductive joint 5 exposed outside except the working surface. The insulating area plays an insulating effect and can avoid the occurrence of electric leakage.

[0031] Specifically, there are two moving plates 3, and the two moving plates 3 are symmetrically distributed on both sides of the cable storage plate 4. One storage groove for storing the cable 6 can be provided in the cable storage plate 4, or two or more storage grooves for storing the cable 6 can be provided. The resistance detection device 7 is respectively connected to two conductive connectors 5 on the two moving plates 3, and can form a closed loop with one cable 6 on the cable storage plate 4, or can form a closed loop with two cables 6.

[0032] For reference, Figures 1-4 , when the circuit is connected, the power mechanism 2 includes a push-pull plate 201, a telescopic rod 202, a guide seat 203, a guide rod 204, a sliding bearing 205, an inclined groove 206, a push-pull rod 207, a first connecting shaft 208, and a second connecting shaft 209. The push-pull plate 201 is arranged on the top of the detection table 1 and is slidably connected to the detection table 1. The push-pull plate 201 is connected to the output end of the telescopic rod 202, and the other end of the telescopic rod 202 is installed on the detection table 1.

[0033] In order to guide the movement of the push-pull plate 201, two guide seats 203 are arranged on the push-pull plate 201. The two guide seats 203 are respectively located at both ends of the push-pull plate 201. The guide seat 203 cooperates with the guide rod 204. It should be added that a sliding bearing 205 is installed in the guide seat 203, and the guide rod 204 cooperates with the sliding bearing 205. The guide rod 204 is installed on the detection table 1.

[0034] Specifically, there are two inclined grooves 206, and the two inclined grooves 206 are symmetrically distributed on the push-pull plate 201. The push-pull rod 207 is inserted into the inclined groove 206, and the push-pull rod 207 can move along the inclined groove 206. The push-pull rod 207 is slidably connected to the moving plate 3, and the push-pull rod 207 can move back and forth along the moving plate 3, while the moving plate 3 can move left and right. Specifically, a groove is provided at the top of the moving plate 3, and the groove is parallel to the moving plate 3. The push-pull rod 207 is inserted into the groove, and the push-pull rod 207 is slidably connected to the groove.

[0035] More specifically, in order to guide the movement of the moving plate 3, a first connecting shaft 208 and a second connecting shaft 209 are inserted into the detection table 1. The middle part of the moving plate 3 is inserted into the first connecting shaft 208, and the end of the moving plate 3 is sleeved with the second connecting shaft 209. The telescopic rod 202 can be one of a hydraulic cylinder and a pneumatic cylinder or other power mechanisms that can provide linear movement.

[0036] Start the telescopic rod 202. The telescopic rod 202 can push the push-pull plate 201 to move. During the process of the push-pull plate 201 moving along the detection table 1, the push-pull rod 207 inserted into the inclined slot 206 in the push-pull plate 201 will move along the inclined slot 206. During the movement of the push-pull rod 207, it will slide along the moving plate 3 and push the moving plate 3 to move along the first connecting shaft 208 and the second connecting shaft 209. The two inclined slots 206 are symmetrically distributed on the push-pull plate 201. During the movement of the push-pull plate 201, the moving plates 3 respectively connected to the two push-pull rods 207 will move towards each other or away from each other. When the moving plates 3 approach each other, the conductive connectors 5 on the moving plates 5 approach the cable 6 located in the cable storage plate 4. Eventually, the conductive connector 5 is connected to the cable 6, and the resistance detection device 7 can detect the resistance of the cable 6. The connection and disconnection between the cable 6 and the resistance detection device 7 can be controlled by the telescopic rod 202, which is relatively convenient to operate and helps improve the efficiency of detecting the resistance of the cable 6.

[0037] For reference Figure 6 , the cable 6 includes a conductive wire 601, a heat insulation layer 602, and an outer skin 603. The heat insulation layer 602 is wrapped outside the conductive wire 601, and the outer skin 603 is wrapped outside the heat insulation layer 602. Both the heat insulation layer 602 and the outer skin 603 are produced by an extruder. Therefore, before connecting the conductive wire 601 to the conductive connector 5, it is necessary to peel off the heat insulation layer 602 and the outer skin 603 to expose the internal conductive wire 601. The heat insulation layer 602 is made of polyvinyl chloride material.

[0038] In order to prevent the cable 6 from loosening after being connected to the conductive connector 5, a cable clamping mechanism 8 is provided on the cable storage plate 4. There are two cable clamping mechanisms 8, and the two cable clamping mechanisms 8 are respectively located on both sides of the cable storage plate 4.

[0039] Specifically, the cable clamping mechanism 8 includes a lower clamping plate 801, an upper clamping plate 802, a lower insulating sleeve 803, an upper insulating sleeve 804, a threaded rod 805, and a power motor 806. The lower clamping plate 801 and the upper clamping plate 802 are respectively located above and below the cable 6. One end of the lower clamping plate 801 is in contact with the outer wall of the cable storage plate 4 and can slide up and down relative to the outer wall of the cable storage plate 4. The upper clamping plate 802 is aligned with the lower clamping plate 801 up and down, and the upper clamping plate 802 abuts against the outer wall of the cable storage plate 4. The threaded rod 805 is provided with two sets of thread portions with opposite thread directions corresponding to the positions of the lower clamping plate 801 and the upper clamping plate 802. The output end of the power motor 806 is connected to the threaded rod 805 through a coupling. The power motor 806 is installed on the cable storage plate 4 through a motor bracket.

[0040] More specifically, the lower insulating sleeve 803 is inserted into the lower clamping plate 801, and the upper insulating sleeve 804 is inserted into the upper clamping plate 802.

[0041] The driving motor 806 starts and can drive the threaded rod 805 to rotate. When the threaded rod 805 rotates, it can drive the lower clamping plate 801 and the upper clamping plate 802 to approach or move away from each other. When the lower clamping plate 801 and the upper clamping plate 802 approach each other, the cable 6 and the conductive joint 5 can be clamped, so that the cable 6 and the conductive joint 5 are kept in a connected state, avoiding inaccurate measurement data caused by poor contact between the current 6 and the conductive joint 5 during the resistance detection of the cable 6. When the lower clamping plate 801 and the upper clamping plate 802 move away from each other, the clamped cable 6 and the conductive joint 5 can be separated, and subsequent separation work of the cable 6 can be carried out.

[0042] To facilitate the loading and unloading of the cable 6, a support plate 9 and a cylinder 10 are provided at the cable storage plate 4. The cable storage plate 4 is installed on the support plate 9, and the support plate 9 is movably connected to the detection table 1. Specifically, the support plate 9 is sleeved on the first connecting shaft 208, the output end of the cylinder 10 is movably connected to the support plate 9, and the other end of the cylinder 10 is movably connected to the detection table 1.

[0043] When the cylinder 10 starts, it can push the support plate 9 and the cable storage plate 4 to rotate around the first connecting shaft 208 to adjust the angle of the cable storage plate 4. When the cable storage plate 4 rotates downward, the storage groove can be exposed, and the cable 6 in the storage groove is staggered up and down with the moving plate 3, making it more convenient to take and place the cable 6.

[0044] In summary: The embodiment of the present invention provides a cable and its production device. When the telescopic rod 202 is started, the telescopic rod 202 can push the push-pull plate 201 to move. During the process of the push-pull plate 201 moving along the detection table 1, the push rod 207 inserted into the inclined groove 206 in the push-pull plate 201 will move along the inclined groove 206. During the movement of the push rod 207, it will slide along the moving plate 3 and push the moving plate 3 to move along the first connecting shaft 208 and the second connecting shaft 209. The two inclined grooves 206 are symmetrically distributed on the push-pull plate 201. During the movement of the push-pull plate 201, the moving plates 3 respectively connected to the two push rods 207 will move in the direction of approaching or moving away from each other. When the moving plates 3 approach each other, the conductive joints 5 on the moving plates 3 approach the cable 6 located in the cable storage plate 4, and finally the conductive joint 5 is connected to the cable 6. The resistance detection device 7 can detect the resistance of the cable 6. The connection and disconnection between the cable 6 and the resistance detection device 7 can be controlled by the telescopic rod 202, and the operation is relatively convenient, which helps to improve the efficiency of the resistance detection of the cable 6.

[0045] The driving motor 806 starts and can drive the threaded rod 805 to rotate. When the threaded rod 805 rotates, it can drive the lower clamping plate 801 and the upper clamping plate 802 to approach or move away from each other. When the lower clamping plate 801 and the upper clamping plate 802 approach each other, the cable 6 and the conductive joint 5 can be clamped, so that the cable 6 and the conductive joint 5 are kept in a connected state, avoiding the situation that the measured data is inaccurate due to poor contact between the current 6 and the conductive joint 5 during the process of detecting the resistance of the cable 6. When the lower clamping plate 801 and the upper clamping plate 802 move away from each other, the clamped cable 6 and the conductive joint 5 can be separated, and the subsequent separation work of the cable 6 can be carried out.

[0046] The above-disclosed are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.
