Description

Technical Field

[0001] This invention relates to the field of cables, and more specifically, to a cable core stranding device. Background Technology

[0002] Cable core stranding device is a key piece of equipment used in the cable manufacturing process. Its main function is to strand multiple thin wires into a cable core according to certain rules and process requirements. However, the existing cable core stranding method is mostly to send multiple groups of single-strand wires into a stranding machine after passing them through a single-group stranding spool. The stranded wires have a large bending degree, which can easily cause the wires to be pulled and broken, resulting in poor quality of the finished product.

[0003] For example, the specification of the "A Cable Core Stranding Device" disclosed in Chinese Invention Patent (Application No.: 202310547478.5) states that: the existing cable core stranding methods mostly involve feeding multiple groups of single-strand wires into a stranding machine after passing them through a single-group stranding reel. The stranded wires have a large bending degree, which makes them very easy to bend. The conductor core of the cable formed by this method is relatively loose and not tightly stranded, resulting in poor product quality and affecting the safety of electricity use in the future. The above patent can corroborate the defects of the existing technology.

[0004] Therefore, we have made improvements to this and proposed a cable core stranding device. Summary of the Invention

This results in stranded wires with a large degree of bending, which easily leads to wire breakage and poor quality of the final product.

[0006] To achieve the above-mentioned objectives, the present invention provides a cable core stranding device to improve the aforementioned problems.

[0018] As a preferred technical solution of this application, the cavity is provided with an exhaust hole, and springs are provided on the corresponding surfaces of the cavity and the striking block.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] In the scheme of this application:

[0021] 1. In order to solve the problem that the existing cable core stranding method mostly involves feeding multiple groups of single-strand wires into a stranding machine after passing them through a single-group stranding spool, resulting in large bending of the stranded wires, which easily leads to wire breakage and poor quality of the finished product, this application uses an adjustment mechanism to pre-deform the wires. Pre-deformation reduces excessive bending and stress concentration of the wires during stranding, thereby reducing the problem of excessive bending and easy breakage of the wires.

[0022] 2. By using an adjustment mechanism, the rubber ring is driven to clean impurities from the surface of the wire, ensuring that the wires are tightly bonded during the stranding process and forming a uniform stranded structure. This solves the problem of loose stranding caused by impurities on the surface of the wire in the prior art.

[0023] 3. By setting an adjustment mechanism, the striking block is driven to strike the cavity, causing the stranding disc to vibrate. The vibration can make the wires evenly distributed during the stranding process, reducing local accumulation and looseness, thereby improving the uniformity of stranding and solving the problem of cable electrical performance degradation caused by local accumulation and looseness in the existing technology.

[0024] 4. Through the set adjustment mechanism, the air in the cavity is discharged by striking the block. The discharged air acts on the wire, realizing cold blowing on the wire. Cold blowing reduces the static electricity on the surface of the wire and reduces the adsorption of impurities on the surface of the stranded cable. It solves the problem of static electricity accumulation attracting impurities and causing the insulation layer of the cable to become thinner in the existing technology. Attached Figure Description

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0036] As described in the background section, existing cable core stranding methods mostly involve feeding multiple groups of single-strand wires through a single-group stranding reel into a stranding machine for stranding. The stranded wires have a large bending degree, which makes them very easy to bend, resulting in poor quality of the final product.

[0037] To solve this technical problem, the present invention provides a cable core stranding device, which is applied to cables.

[0038] For details, please refer to Figures 1-7As shown, the cable core stranding device specifically includes: a base 1, a fixed plate 101 disposed on the base 1, a fixed seat 102 disposed on the fixed plate 101, a take-up roller 103 rotatably disposed on the fixed seat 102, a stranding mold 104 disposed on the base 1, a take-up mechanism 105 disposed on the base 1, and an adjustment mechanism 2 disposed on the base 1. In the prior art, the wire is wound around the outside of the take-up roller 103. The fixed plate 101, the fixed seat 102 and the take-up roller 103 constitute the existing wire release mechanism, which is used to release the wire and maintain appropriate tension. The stranding mold 104 is used to guide the wire to be pressed and shaped during the stranding process to form the required cable structure. The take-up mechanism 105 is used to guide and stretch the stranded cable and collect the stranded cable.

[0039] The adjustment mechanism 2 includes a motor 201 mounted on the base 1, a rotating shaft 202 mounted on the output end of the motor 201, a twisting disc 203 rotatably mounted on the base 1, an adjustment disc 204 rotatably mounted on the base 1, a hollow tube 205 fixedly passing through the twisting disc 203 and the adjustment disc 204, a secondary cable hole 206 mounted on the twisting disc 203, and a transmission roller 207 rotatably mounted on the adjustment disc 204.

[0040] The cable core stranding device provided by this invention addresses the problem that existing cable core stranding methods often involve feeding multiple groups of single-strand wires through a single-group stranding reel into a stranding machine for stranding. This results in a large bending degree in the stranded wires, making them prone to breakage and leading to poor quality of the final product. This application addresses this issue by using an adjustment mechanism 2 to pre-deform the wires. This pre-deformation reduces excessive bending and stress concentration during the stranding process, thus reducing the likelihood of excessive bending and breakage.

[0041] By using the adjustment mechanism 2, the rubber ring 211 is driven to clean the impurities on the surface of the wire, so that the wire is tightly bonded during the stranding process, forming a uniform stranded structure, which solves the problem of loose stranding caused by impurities on the surface of the wire in the prior art.

[0042] By using the adjustment mechanism 2, the striking block 226 is driven to strike the cavity 225, causing the stranding disc 203 to vibrate. This vibration allows the wires to be evenly distributed during the stranding process, reducing local accumulation and looseness, thereby improving the uniformity of stranding and solving the problem of cable electrical performance degradation caused by local accumulation and looseness in the prior art.

[0043] By using the adjustment mechanism 2, the air inside the cavity 225 is expelled by the striking block 226. The expelled air acts on the wire, achieving cold blowing on the wire. Cold blowing reduces static electricity on the surface of the wire and reduces the adsorption of impurities on the surface of the stranded cable. This solves the problem in the prior art where static electricity accumulation attracts impurities, causing the insulation layer of the cable to become thinner.

[0044] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0045] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0046] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0047] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a cable core stranding device has a rotating shaft 202 rotatably mounted on a base 1. A drive gear 208 is mounted on the rotating shaft 202, and a transmission gear 209 is mounted on the stranding disc 203. The drive gear 208 and transmission gear 209 are mutually compatible. In use, the motor 201 is started, and its output drives the rotating shaft 202 to rotate. The rotating shaft 202 drives the drive gear 208 to rotate, which in turn drives the transmission gear 209. The transmission gear 209 drives the stranding disc 203 to rotate, which in turn drives the hollow tube 205 and the adjusting disc 204 to rotate synchronously. The wires slide on the auxiliary cable holes 206, and the cores slide at the center of the fixed disc 101 and the hollow tube 205. Multiple wires and cores pass through the stranding mold 104. Figure 1 As shown, the twisting disc 203 rotates to wind the wire around the outside of the battery cell, achieving the twisting operation. When the wire passes the rotating roller, it wraps around the outside of the roller once and exits through the auxiliary cable hole 206. Figure 5 As shown, the wire is pre-deformed during the stranding process. This pre-deformation reduces excessive bending and stress concentration in the wire during stranding, and reduces the likelihood of the wire being bent too much and easily broken. The existing take-up mechanism 105 guides and stretches the stranded cable and collects the stranded cable.

[0048] Furthermore, the outer side of the hollow tube 205 is cross-shaped, and a sliding disk 210 is slidably disposed on the hollow tube 205. A rubber ring 211 is rotatably disposed on the sliding disk 210. When the hollow tube 205 rotates, because the outer side of the hollow tube 205 is cross-shaped, the hollow tube 205 will drive the sliding disk 210 to rotate synchronously. The wire slides on the rubber ring 211. When the wire is twisted, the wire will slide along the rubber ring 211. The rubber ring 211 cleans the impurities on the surface of the wire, so that the wire is tightly attached during the twisting process and forms a uniform twisted structure.

[0049] Furthermore, a bevel gear 212 is mounted on the rotating shaft 202, a sliding seat 213 is mounted on the base 1, a drive disk 214 is rotatably mounted on the sliding seat 213, a synchronous shaft 215 is mounted on the drive disk 214, a bevel gear 216 is mounted on the synchronous shaft 215, the bevel gear 212 and the bevel gear 216 are mutually compatible, a pusher pin 217 is mounted on the drive disk 214, and a sliding ring 218 is slidably mounted on the sliding seat 213. 7. A sliding arrangement is provided on the sliding ring 218, and a U-shaped seat 219 is provided on the sliding ring 218. When the output end of the motor 201 drives the rotating shaft 202 to rotate, the rotating shaft 202 drives the first bevel gear 212 to rotate synchronously, the first bevel gear 212 drives the second bevel gear 216 to rotate, the second bevel gear 216 drives the synchronous shaft 215, the drive disc 214 and the jacking column 217 to rotate, and the jacking column 217 drives the sliding ring 218 to slide back and forth along the sliding seat 213. Figure 7 As shown, the U-shaped seat 219 and the sliding ring 218 move synchronously, and the U-shaped seat 219 drives the sliding disk 210 to move synchronously. When the wires are twisted, the sliding disk 210 slides back and forth, and the rubber ring 211 moves synchronously, thereby improving the cleaning efficiency of the rubber ring 211 on the wires.

[0050] Furthermore, a ball bearing 220 is rotatably mounted on the U-shaped seat 219. The ball bearing 220 is adapted to the sliding disk 210. When the twisting disc 203 rotates, the twisting disc 203 drives the hollow tube 205 to rotate, and the hollow tube 205 drives the sliding disk 210 to rotate synchronously. The ball bearing 220 drives the sliding disk 210 to slide back and forth. Compared with the U-shaped seat 219 driving the sliding disk 210 to slide back and forth, this reduces friction and thus reduces the wear between the U-shaped seat 219 and the sliding disk 210.

[0051] Furthermore, the transmission roller 207 is provided with a conical groove 221, and the end of the rubber ring 211 is truncated cone-shaped. The conical groove 221 and the rubber ring 211 are adapted to each other. When the transmission roller 207 releases the wire, the transmission roller 207 will rotate, and the conical groove 221 on the transmission roller 207 will rotate synchronously. The rotation of the conical groove 221 generates wind, which cleans the impurities attached to the end of the rubber ring 211. Because impurities remain at the end of the rubber ring 211 when cleaning the wire, the end of the rubber ring 211 is truncated cone-shaped, which makes it easy for the impurities to detach from the end of the rubber ring 211. Therefore, the remaining impurities are blown away by the wind generated by the rotation of the conical groove 221, preventing the impurities, the wire and the rubber ring 211 from rubbing against each other, which would increase the wear of the wire.

[0052] The wire is pre-deformed by the adjustment mechanism 2, which reduces excessive bending and stress concentration during the stranding process, and reduces the wire from being too bent and easily broken. The rubber ring 211 is driven to clean impurities on the surface of the wire, so that the wire is tightly bonded during the stranding process and forms a uniform stranded structure.

[0053] Example 2 further optimizes the cable core stranding device provided in Example 1, specifically, as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the sliding disk 210 is provided with an arc-shaped groove 222, the rubber ring 211 is provided with a transmission ring 223 on the outside, and the adjusting disk 204 and the twisting disk 203 are provided with irregularly shaped columns 224. The transmission ring 223 is slidably disposed on the irregularly shaped column 224. When the sliding disk 210 slides back and forth along the outside of the hollow tube 205, the rubber ring 211 and the transmission ring 223 slide synchronously with the sliding disk 210, and the transmission ring 223 slides synchronously along the irregularly shaped column 224. The irregularly shaped column 224 drives the transmission ring 223 to slide back and forth along the arc-shaped groove 222, thereby causing the rubber ring 211 to rotate back and forth slightly. Through the back and forth rotation of the rubber ring 211, the rubber ring 211 generates a certain friction force with the wire. Through the friction force, the wire can bend and twist slightly during the transmission process, thereby enhancing the pre-deformation effect.

[0054] Furthermore, the stranding disc 203 is provided with a cavity 225, and a striking block 226 is slidably disposed in the cavity 225. A drive column 227 is slidably disposed on the cavity 225 and disposed on the striking block 226. When the sliding disc 210 reciprocates along the outside of the hollow tube 205, the sliding disc 210 squeezes the drive column 227, and the drive column 227 drives the striking block 226 to slide along the cavity 225. At the same time, the striking block 226 strikes the cavity 225, causing the stranding disc 203 to vibrate. Through vibration, the wires can be evenly distributed during the stranding process, reducing local accumulation and looseness, thereby improving the uniformity of stranding.

[0055] Furthermore, the sliding disk 210 is provided with an annular groove 228, and the striking block 226 is provided with a second ball 229. The second ball 229 and the annular groove 228 are compatible. When the sliding disk 210 reciprocates along the outside of the hollow tube 205, the sliding disk 210 and the hinge disk 203 rotate synchronously. When the sliding disk 210 presses the drive column 227, it contacts the second ball 229 through the annular groove 228, thus reducing the wear between the sliding disk 210 and the drive column 227.

[0056] Furthermore, an exhaust port 230 is provided on the cavity 225, and a spring 231 is provided on the corresponding surface of the cavity 225 and the striking block 226. When the drive column 227 drives the striking block 226 to slide along the cavity 225, the striking block 226 discharges the air in the cavity 225 from the exhaust port 230. The discharged air acts on the wire, thereby realizing the cold blowing of the wire. The cold blowing reduces the static electricity on the surface of the wire and reduces the adsorption of impurities on the surface of the stranded cable.

[0057] The adjusting mechanism 2 drives the striking block 226 to strike the cavity 225, causing the stranding disc 203 to vibrate. The vibration can make the wires evenly distributed during the stranding process, reducing local accumulation and looseness, thereby improving the uniformity of stranding. The striking block 226 expels the air in the cavity 225, and the expelled air acts on the wires, realizing cold blowing on the wires. Cold blowing reduces static electricity on the surface of the wires and reduces the adsorption of impurities on the surface of the stranded cable.

[0058] The cable core stranding device provided by this invention is used as follows:

[0059] In use, the motor 201 is started, and the output of the motor 201 drives the rotating shaft 202 to rotate. The rotating shaft 202 drives the drive gear 208 to rotate, the drive gear 208 drives the transmission gear 209 to rotate, and the transmission gear 209 drives the stranding disc 203 to rotate. The stranding disc 203 drives the hollow tube 205 and the adjusting disc 204 to rotate synchronously. The wires slide on the auxiliary cable hole 206, and the battery core slides at the center of the fixed disc 101 and the hollow tube 205. Multiple wires and battery cores pass through the stranding mold 104 together. Figure 1 As shown, the twisting disc 203 rotates to wind the wire around the outside of the battery cell, achieving the twisting operation. When the wire passes the rotating roller, it wraps around the outside of the roller once and exits through the auxiliary cable hole 206. Figure 5 As shown, during the stranding process, the wire is pre-deformed to reduce excessive bending and stress concentration. The hollow tube 205 drives the sliding disc 210 to rotate synchronously. The rotating shaft 202 drives the first bevel gear 212 to rotate synchronously, which in turn drives the second bevel gear 216 to rotate. The second bevel gear 216 drives the synchronous shaft 215, the drive disc 214, and the jacking column 217 to rotate. The jacking column 217 drives the sliding ring 218 to slide reciprocally along the sliding seat 213. Figure 7 As shown, the U-shaped seat 219 and the sliding ring 218 move synchronously. The ball bearing 220 on the U-shaped seat 219 drives the sliding disk 210 to slide back and forth. When the wire is twisted, the sliding disk 210 slides back and forth, and the rubber ring 211 moves synchronously. The rubber ring 211 cleans the impurities on the surface of the wire. At the same time, the transmission roller 207 releases the wire and rotates. The conical groove 221 on the transmission roller 207 rotates synchronously. The rotation of the conical groove 221 generates wind, which cleans the impurities attached to the end of the rubber ring 211. When the sliding disk 210 slides back and forth along the outside of the hollow tube 205, the rubber ring 211 and the transmission ring 223 slide synchronously with the sliding disk 210. The transmission ring 223 slides synchronously along the irregular column 224. The irregular column 224 drives the transmission ring 223 along the arc groove 224. The 22 slides back and forth, causing the rubber ring 211 to rotate back and forth slightly. Through the back and forth rotation of the rubber ring 211, a certain frictional force is generated between the rubber ring 211 and the wire. This frictional force can cause the wire to bend and twist slightly during the transmission process, thereby enhancing the pre-deformation effect. The sliding disc 210 presses the drive column 227, which drives the striking block 226 to slide along the cavity 225. At the same time, the striking block 226 impacts the cavity 225, causing the stranding disc 203 to vibrate. This vibration can make the wire evenly distributed during the stranding process, reducing local accumulation and looseness. Meanwhile, the striking block 226 discharges the air in the cavity 225 through the exhaust hole 230. The discharged air acts on the wire, thereby achieving cold blowing on the wire and reducing static electricity on the surface of the wire.
