Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and in particular to a cable processing device and a processing method thereof. Background Art

[0002] Cables are indispensable in modern society. In the manufacturing process of power cables, the entire processing system production line is very long and almost uninterrupted. Therefore, every processing link needs to be preset in advance to avoid problems as much as possible. Adhesion and sticking are likely to occur between the insulated conductor core and the outer sheath, especially when extruding the outer sheath around the insulated conductor core or the stranded conductor through an extruder. This adhesion and sticking not only seriously affect the flexibility of the cable, affect the subsequent processing and laying installation of the cable, but also cause difficulties in cable peeling. More seriously, when the cable is bent, it may even cause the insulation layer to tear, reducing the service life of the cable and posing a safety hazard. In the industry, talcum powder is usually coated on the insulated conductor core as a cable separator. Talcum powder is a heat-absorbing substance to facilitate the separation of the conductor core and the sheath.

[0003] Usually, the cable after stranding is first wrapped with a layer of thin film Mylar tape, and then a layer of isolating and flame-retardant cotton paper is wound around the outer layer of the thin film, which can protect the cable from being damaged by the armor and ensure that the cable core does not become loose. These processes are collectively called winding.

[0004] Most of the existing cable processing winding devices directly coat talcum powder on the outside of the cable core and then perform winding to achieve a double isolation effect. However, after the talcum powder is coated, it has a certain thickness, and the insulating paper also has a thickness. And usually, in order to fully wrap the cable, the insulating paper is wound in a spiral, and there will be overlapping parts during winding. This results in the thickness of the overlapping part being the sum of the thicknesses of two layers of paper and powder, causing uneven thickness, wasting materials, and affecting the subsequent extrusion of the sheath. Therefore, it does not meet the existing requirements, and for this reason, we propose a cable processing device and a processing method thereof. Summary of the Invention

Move and fix the bracket, and press the clamping roller against the lower side of the insulating cloth so that the insulating cloth is clamped between the clamping roller and the duckbill cylinder.

[0018] S3. Adjust the powder box above the guiding roller so that the powder coating roller contacts the insulating cloth.

[0020] S5. Start the operation of the motor and the entire cable processing system, and the cable core moves during the transmission of the cable processing system.

[0021] The present invention has the following beneficial effects:

[0022] 1. The cable processing equipment and its processing method. Through the setting of the wire guiding cylinder, the cable core in the entire processing system can be limited within a certain range. Even if the cable core moves under force during processing, its movement range is limited, ensuring the overall stability. Through the cooperation of the duckbill cylinder and the clamping roller, a part of the insulating cloth rotates under the friction of the duckbill cylinder and the clamping roller, thereby driving the entire insulating cloth to wind. Since the cable core is moving, the insulating cloth outside the duckbill cylinder will be pulled to the outside of the cable core, thus realizing the full wrapping of the cable core by the insulating cloth, which can protect the cable from being damaged by the armor and also ensure that the cable core will not become loose;

[0023] By distinguishing the overlapping area and the powder coating area, when applying talcum powder to the insulating cloth, it is possible to consciously apply powder only to the powder coating area, saving materials. As a result, after the insulating cloth is wound, the thickness of the overlapping part of the insulating cloth will not increase additionally. There is talcum powder on the inner side of the normal wrapping of the insulating cloth, further improving the isolation between the cable core and the outside world, and the overall cable core after the insulating cloth is wound is smoother, facilitating the subsequent extrusion of the sheath outside the cable core.

[0024] 2. The cable processing equipment and its processing method. By setting a powder collecting port inside the powder box, the internal space of the powder box is divided into two parts. The upper space is used to store talcum powder, and the talcum powder exits downward through the powder collecting port, so that the talcum powder is sprinkled on the upper side of the powder coating roller. When the insulating cloth moves, the powder coating roller is driven to rotate, and the talcum powder on it will rotate downward and be coated on the insulating cloth; there is an adhesive layer on the upper side of the insulating cloth, and the adhesive layer can fixedly adhere a layer of talcum powder. The excess talcum powder will disperse during the movement process. Therefore, the finally retained talcum powder is basically the adhered part, realizing uniform powder coating, making the overall thickness of the insulating cloth uniform, and further improving the smoothness of the overall cable core.

[0025] 3. The cable processing equipment and its processing method. Through the cooperation of the screw rod, the slide rod and the slider, a screw rod slide table is formed. The powder box is installed at the bottom of the slider. By turning the crank handle, the slider moves, so that the position of the powder box can be adjusted. The amount of contact area between the powder coating roller and the insulating cloth represents the change in the powder coating width, that is, the change in the width of the powder coating area. Therefore, by turning the crank handle, the adjustment of the powder coating width can be realized, which is more flexible in use, has a wider application range, and stronger practicability.

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1

[0037] The purpose of this embodiment is to facilitate the solution of the existing cable processing and winding equipment. Most of them directly coat talcum powder on the outer side of the cable core and then wind it to achieve a double isolation effect. However, after the talcum powder is coated, it has a certain thickness, and the insulating paper also has a thickness. And usually, in order to fully wrap the cable, the insulating paper is wound spirally, and there will be overlapping parts during winding. This results in the thickness of the overlapping parts being the sum of the thicknesses of two layers of paper and powder, causing uneven thickness, wasting materials, and affecting the subsequent extrusion of the sheath. Please refer to Figures 1 - 7 , a cable processing equipment, including a cable core 130, an insulating cloth 140, and a winding disc 110. A wire guiding tube 120 is rotatably installed at the center of the winding disc 110. The cable core 130 passes through the wire guiding tube 120. A motor 300 is installed on the back side of the winding disc 110, and the motor 300 is in transmission connection with the wire guiding tube 120. Specifically, when setting, seeFigure 2 On the outside of the wire winding cylinder 120, a driven gear 320 is key-connected. On the outside of the output shaft of the motor 300, a driving gear 310 is installed, and the driving gear 310 meshes with the driven gear 320.

[0038] A cloth roller 170 is rotatably installed on the front side of the wrapping disc 110, and the insulating cloth 140 is wound and stored on the outside of the cloth roller 170.

[0039] During specific setting, see Figure 1 and Figure 3 On the side of the wrapping disc 110, a rotating shaft 180 is installed, and the cloth roller 170 is rotatably installed on the outside of the rotating shaft 180. The cloth roller 170 is set as an I-shaped roller. When the insulating cloth 140 on the cloth roller 170 is used up, the cloth roller 170 can be removed from the rotating shaft 180 for replacement.

[0040] A guiding roller 220 is rotatably installed on the side of the wrapping disc 110. One end of the wire winding cylinder 120 is connected with a duckbill cylinder 160. One end of the insulating cloth 140 bypasses the guiding roller 220, and the insulating cloth 140 is spirally wound on the outside of the cable core 130 and the duckbill cylinder 160. Talcum powder 150 is arranged between the insulating cloth 140 and the cable core 130.

[0041] Meanwhile, an auxiliary roller 210 is rotatably installed on the side of the wrapping disc 110. The auxiliary roller 210 is arranged between the guiding roller 220 and the cloth roller 170. The auxiliary roller 210 is arranged on the lower oblique side of the guiding roller 220. One end of the insulating cloth 140 bypasses the upper side of the auxiliary roller 210, and then the insulating cloth 140 bypasses the lower side of the guiding roller 220.

[0042] After the insulating cloth 140 changes direction through the auxiliary roller 210 and the guiding roller 220, the middle part thereof presents a √ shape.

[0043] See Figure 4 The duckbill cylinder 160 is set as a streamline cylinder. The diameter of the outlet end of the duckbill cylinder 160 is smaller than the diameter of the wire winding cylinder 120. The insulating cloth 140 is obliquely wound on the outside of the duckbill cylinder 160 and the cable core 130. The overlapping part of the insulating cloth 140 during winding is set as an overlapping area 141, and the non-overlapping part of the insulating cloth 140 is set as a powder coating area 142. The talcum powder 150 is distributed in the powder coating area 142. Friction is generated at the part where the insulating cloth 140 contacts the duckbill cylinder 160. When the duckbill cylinder 160 rotates, the frictional force winds up the insulating cloth 140, so that the insulating cloth 140 is wound. And during specific setting, the insulating cloth 140 is wound in an inclined spiral. The cable core 130 is movable. Therefore, the insulating cloth 140 outside the duckbill cylinder will be pulled to the outside of the cable core 130, so as to realize the full wrapping of the cable core 130 by the insulating cloth 140.

[0044] To improve the friction effect, a clamping roller 190 is provided on the bottom side of the duckbill cylinder 160. The clamping roller 190 is set as a rubber roller, and the clamping roller 190 is in rolling contact with the bottom side of the insulating cloth 140. A bracket 192 is provided on the side of the wrapping disc 110. The clamping roller 190 is rotatably installed at one end of the bracket 192. A chute 193 is formed on the side of the wrapping disc 110, and the other end of the bracket 192 is slidably installed in the chute 193. A limiting block 191 is installed on the outer side of the bracket 192. Threaded holes are provided on both sides of the limiting block 191 for installing bolts. The limiting block 191 is fixedly locked with the wrapping disc 110 through bolts, so that the position of the bracket 192 is fixed to adjust and fix the clamping degree.

[0045] Through the arrangement of the clamping roller 190, the insulating cloth 140 remains in contact with the duckbill cylinder 160, thereby maintaining the stability of winding.

[0046] See Figure 6 , an adhesive layer 143 is provided on the upper side of the insulating cloth 140, and talcum powder 150 is adhered above the adhesive layer 143.

[0047] Specifically, a powder box 200 is provided above the guiding roller 220. The powder box 200 stores talcum powder 150 inside. A powder coating roller 280 is rotatably installed at the bottom of the powder box 200. The powder coating roller 280 is arranged on one side close to the powder coating area 142. The powder coating roller 280 is in rolling contact with the powder coating area 142, so that only the powder coating area 142 is coated with powder. See Figure 8 , after the insulating cloth 140 is wound, there is no powder in the overlapping area 141, the powder coating area 142 is normally coated with powder, and the adhesive layer 143 can fixedly adhere a layer of talcum powder 150. The excess talcum powder 150 will spread during the movement. When contacting the duckbill cylinder 160, due to the characteristics of the talcum powder 150, the insulating cloth 140 will not adhere to the duckbill cylinder 160. Therefore, the finally retained talcum powder 150 is basically the adhered part, realizing uniform powder coating, making the overall thickness of the insulating cloth 140 uniform, and further improving the smoothness of the overall cable core.

[0048] In this embodiment: Through the arrangement of the wire guiding cylinder 120, the cable core 130 in the entire processing system can be limited within a certain range. Even if the cable core 130 moves under force during processing, its movement range is limited, ensuring the overall stability. Through the cooperation of the duckbill cylinder 160 and the clamping roller 190, a part of the insulating cloth 140 rotates under the friction of the duckbill cylinder 160 and the clamping roller 190, thereby driving the entire insulating cloth 140 to wind. Since the cable core 130 is moving, the insulating cloth 140 outside the duckbill cylinder 160 will be pulled to the outside of the cable core 130, thereby realizing the full wrapping of the cable core 130 by the insulating cloth 140, which can protect the cable from being damaged by the armor and ensure that the cable core will not be loose;

[0049] By distinguishing the overlapping area 141 and the powder coating area 142, when applying talcum powder 150 to the insulating cloth 140, it is possible to consciously apply powder only to the powder coating area 142, saving materials. As a result, after the insulating cloth 140 is wound, the thickness of the overlapping part of the insulating cloth 140 will not increase additionally, and there is talcum powder 150 on the inner side of the normal wrapping of the insulating cloth 140, further improving the isolation between the cable core 130 and the outside world, and the overall cable core after the insulating cloth 140 is wound is smoother, facilitating the subsequent extrusion of the sheath on the outside of the cable core;

[0050] There is an adhesive layer 143 on the upper side of the insulating cloth 140. The adhesive layer 143 can fixedly adhere a layer of talcum powder 150. The excess talcum powder 150 will spread during the movement. Therefore, the finally retained talcum powder 150 is basically the adhered part, realizing uniform powder coating, making the overall thickness of the insulating cloth 140 uniform, and further improving the smoothness of the overall cable core.

[0051] Embodiment 2

[0052] The purpose of this embodiment is to facilitate the solution of the problem that due to different winding angles, the areas of the overlapping area 141 and the powder coating area 142 are different, so the width of the powder coating of the insulating cloth 140 by the powder box 200 needs to be adjusted. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1 - 7 , a screw rod 230 is rotatably installed on the side of the wrapping disc 110, and a sliding rod 240 is fixedly installed on the side of the wrapping disc 110. A slider 250 is jointly sleeved on the outer sides of the screw rod 230 and the sliding rod 240. The three are combined into a screw rod sliding table. The powder box 200 is installed on the lower side of the slider 250 through bolts. The sliding rod 240 is of the same length as the screw rod 230, and a limiting plate 260 is welded and installed at the end of the sliding rod 240. The screw rod 230 penetrates through the limiting plate 260, and a crank 270 is rotatably arranged on the outer side of the limiting plate 260. The crank 270 is connected to the screw rod 230. By shaking the crank 270, the slider 250 moves, so that the position of the powder box 200 can be adjusted.

[0053] See Figure 6 and Figure 7 , a powder collecting port 290 is arranged inside the powder box 200. The powder collecting port 290 is set as a downward leakage type outlet. The powder collecting port 290 is arranged directly above the powder coating roller 280. In this embodiment, the powder coating roller 280 is set as a brush roller. The powder collecting port 290 divides the internal space of the powder box 200 into two parts. The upper space is used to store talcum powder 150. The talcum powder 150 exits downward through the powder collecting port 290, so that the talcum powder 150 is sprinkled on the upper side of the powder coating roller 280. When the insulating cloth 140 moves, the powder coating roller 280 is driven to rotate, and the talcum powder on it will rotate downward and be coated on the insulating cloth 140.

[0054] In this embodiment: Through the cooperation of the screw rod 230, the slide rod 240 and the slider 250, a lead screw slide table is assembled. The powder box 200 is installed at the bottom of the slider 250. By shaking the crank 270, the slider 250 moves, so that the position of the powder box 200 can be adjusted. The amount of the contact area between the powder coating roller 280 and the insulating cloth 140 represents the change in the powder coating width, that is, the width change of the powder coating area 142. Therefore, by shaking the crank 270, the adjustment of the powder coating width can be realized, which is more flexible to use, has a wider application range and stronger practicability.

[0055] Embodiment 3

[0056] A cable processing method includes the following specific steps:

[0057] S1. Pass the cable core 130 to be processed through the wire guiding cylinder 120, and ensure that both the wire guiding cylinder 120 and the duckbill cylinder 160 are in clearance fit with the cable core 130;

[0058] S2. Pass one end of the insulating cloth 140 around the lower side of the auxiliary roller 210, then around the upper side of the guiding roller 220, and helically wind the end around the outside of the duckbill cylinder 160 and the cable core 130. Move and fix the bracket 192, and press the clamping roller 190 against the lower side of the insulating cloth 140, so that the insulating cloth 140 is clamped between the clamping roller 190 and the duckbill cylinder 160;

[0059] S3. Adjust the powder box 200 above the guiding roller 220 so that the powder coating roller 280 contacts the insulating cloth 140;

[0060] S4. Determine the widths of the overlapping area 141 and the powder coating area 142 according to the size of the overlapping part of the insulating cloth 140 after winding, and then shake the crank 270 to adjust the position of the powder box 200 to align the side wall of the powder coating roller 280 with the boundary of the powder coating area 142;

[0061] S5. Start the motor 300 and the operation of the entire cable processing system. The cable core 130 moves during the transmission of the cable processing system. While the cable core 130 is translating, the powder coating roller 280 applies talcum powder 150 to the powder coating area 142 of the insulating cloth 140. The insulating cloth 140 is driven by the duckbill cylinder 160 to wind around the cable core 130, realizing the full wrapping of the cable core 130, and there is no talcum powder 150 in the overlapping area 141, saving materials, reducing costs, improving the powder coating uniformity, making the overall thickness of the insulating cloth 140 uniform, further improving the overall smoothness of the cable core, and being beneficial to the subsequent processing procedure of sheath extrusion.
