Description

Technical Field

[0001] This utility model relates to the field of enameled wire production technology, specifically to an automatic stranding device for composite enameled wire. Background Technology

[0002] With the rapid development of the electronics industry, composite enameled wires are increasingly widely used in motors, transformers, household appliances and other fields because they combine the excellent properties of different enamel materials.

[0003] Existing enameled wire stranding equipment has difficulty controlling the stranding tension of each enameled wire during the bonding process, resulting in a decrease in stranding quality. At the same time, the wire feeding and take-up reels in existing equipment need to be manually disassembled and positioned, which greatly reduces the smoothness of the production cycle and thus reduces production efficiency. To address this, we provide an automatic stranding device for composite enameled wires. Utility Model Content

[0004] The purpose of this invention is to provide an automatic stranding device for composite enameled wire.

[0005] The technical problem solved by this utility model is: (1) The twisting tension of enameled wire cannot be adaptively adjusted;

[0010] The take-up assembly includes a symmetrically arranged support frame and a take-up reel rotatably disposed between the two. A cycloidal mechanism is provided on one side of the take-up reel to apply reciprocating lateral displacement to the stranded cable.

[0011] A further technical improvement of this utility model is that: four conveying wheels are evenly arranged on the outer periphery of the rotating disk, and the outer periphery of the four conveying wheels rolls in contact with the rotating disk to limit the rotation disk; a toothed ring is also fitted and fixed on the outer periphery of the rotating disk; a transmission gear is rotatably mounted on the wire feeding box below the rotating disk; the toothed ring meshes with the transmission gear for transmission; and the transmission gear is driven by a motor.

[0012] A further technical improvement of this utility model is that each pulley assembly includes a fixed pulley and a movable pulley. The movable pulley slides relative to the fixed pulley in the radial direction, and the movable pulley is subjected to an elastic force opposite to the direction of movement when it approaches the fixed pulley. The fixed pulley is positioned close to the threading sleeve.

[0013] A further technical improvement of this utility model is that a wire guide plate is coaxially installed on the side of the rotating disk away from the wire feeding structure. The wire to be twisted passes through the straightening wheel group and the wire threading sleeve from the wire feeding wheel, and passes around the fixed pulley and the movable pulley before passing through the wire hole on the wire guide plate.

[0014] A further technical improvement of this utility model is that the center height of the strand drum is consistent with the center height of the wire guide spool.

[0015] A further technical improvement of this utility model is that the stranded cable assembly also includes a second straightening wheel group for straightening the stranded cable. The first straightening wheel group and the second straightening wheel group include two rotatable straightening wheels, and the distance between them matches the cable diameter.

[0016] A further technical improvement of this utility model is that: the cycloidal mechanism includes a cycloidal frame fixed to one side of the support frame, a slider is slidably provided on the top of the cycloidal frame, the slider is driven to reciprocate by a double-wire reciprocating screw inside the cycloidal frame, a cycloidal rod is installed on the top of the slider, and the cable swings laterally back and forth through the cycloidal rod.

[0017] A further technical improvement of this utility model is that the pay-off reel or take-up reel in the pay-off structure is installed and disassembled through a quick-change reel structure; the quick-change reel structure includes an electromagnetic driver disposed in the side wall of a reel bracket, the output end of the electromagnetic driver is rotatably provided with a positioning rod and the positioning rod moves synchronously with the output end of the electromagnetic driver, and the end of the positioning rod away from the electromagnetic driver is provided with a spline that cooperates with the center hole of the reel.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This utility model uses a pulley assembly with spring pre-tensioning and tensioning, which can automatically compensate for the tension of the cable during stranding according to the winding and unwinding speed of each cable, avoiding loose stranding or paint film damage caused by uneven tension, and significantly improving the uniformity of stranded cables and the finished product qualification rate.

[0021] 2. This utility model achieves low-friction cable conveying by setting a straightening wheel set, while maintaining the cable tension. In particular, the straightening wheel set can prevent the cable from loosening due to self-rotation after twisting.

[0022] 3. This utility model achieves synchronous traction and uniform winding of stranded cables by setting up a cycloidal mechanism and a winding wheel in rotational linkage; the reciprocating motion of the cycloidal rod makes the cable automatically distributed, avoiding local accumulation on the winding wheel, and improving the cable winding density and appearance consistency.

[0023] 4. This utility model achieves quick assembly and disassembly of the pay-off reel and take-up reel through the cooperation of the electromagnetic driver and the spline positioning structure, eliminating the need for manual assembly and disassembly and greatly improving efficiency.

[0032] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0033] Please see Figure 1-3 As shown, an automatic stranding device for composite enameled wire includes a base plate 1, and a wire feeding assembly 2, a wire stranding assembly 3 and a wire take-up assembly 4 are sequentially installed on the top of the base plate 1.

[0034] The wire feeding assembly 2 includes a wire feeding box 201 vertically mounted on the top of the base plate 1. A rotating disk 202 is rotatably installed inside the wire feeding box 201. Multiple sets of wire feeding structures 204 and straightening wheel sets 205 are evenly installed at equal angles on the side of the rotating disk 202 away from the stranded wire assembly 3, and each set of wire feeding structures 204 corresponds one-to-one with the straightening wheel set 205. A wire guide plate 203 is coaxially arranged on the side of the rotating disk 202 near the stranded wire assembly 3, and the wire guide plate 203 is fixedly connected to the side wall of the rotating disk 202 through multiple support columns, so that the wire guide plate 203 can rotate synchronously with the rotating disk 202. At the same time, multiple pulley assemblies are evenly arranged at equal angles on the side of the rotating disk 202 near the wire guide plate 203, and the number of pulley assemblies is equivalent to the number of wire feeding structures 204.

[0035] A threading sleeve 206 is provided through the center of the rotating disk 202. The threading sleeve 206 is generally made of copper. The wire feeding structure 204 includes a wire feeding frame 2041 and a wire feeding wheel. The straightening wheel group 205 includes two adjacent straightening wheels that are rotatably mounted on the bracket. The gap between the two straightening wheels is matched to the wire diameter required for feeding.

[0036] Each pulley assembly includes a fixed pulley 210 close to the threading sleeve 206 and a movable pulley 211 away from the threading sleeve 206. The mounting bracket of the movable pulley 211 is slidably disposed in a groove opened in the side wall of the rotating disk 202. A spring 212 is installed in the groove. The two ends of the spring 212 abut against the movable pulley 211 and the groove wall respectively, so that the movable pulley 211 always tends to move away from the fixed pulley 210.

[0037] Located inside the wire feeding box 201, a gear ring 208 is coaxially fixed on the outer periphery of the rotating disk 202. A transmission gear 209 is rotatably mounted directly below the rotating disk 202. The transmission gear 209 meshes with the gear ring 208 for transmission. The transmission gear 209 is driven by a motor (not shown in the figure). Four conveying wheels 207 are evenly arranged on the outer periphery of the rotating disk 202, which roll in contact with the outer shaft stepped surface. The conveying wheels 207 are rotatably mounted inside the wire feeding box 201.

[0038] In the wire feeding assembly 2, the wires to be twisted on each wire feeding reel are pulled through between the two straightening reels of the corresponding straightening reel group 205, and then through the wire threading sleeve 206 and as follows. Figure 4 The cable passes through the fixed pulley 210 and the movable pulley 211 in sequence, and then the cable to be stranded passes through the evenly spaced holes on the cable guide 203 and extends into the subsequent stranding assembly 3.

[0039] The stranding assembly 3 includes a mounting bracket 301 fixedly mounted on the top of the base plate 1. A lower base plate 302 is horizontally fixedly mounted on the top of the mounting bracket 301. An upper base plate 303 is fixedly mounted on the top of the lower base plate 302. Semicircular holes are provided on the opposite surfaces of the lower base plate 302 and the upper base plate 303. The two semicircular holes form a complete mounting hole, and a stranding drum 304 is rotatably mounted in the mounting hole. A second straightening wheel set 305 is fixedly mounted on one side of the mounting bracket 301. The second straightening wheel set 305 has the same structure as the first straightening wheel set 205, and its component size is adapted to the cable. Multiple cables to be stranded pass through the stranding drum 304 and extend through the second straightening wheel set 305 to the subsequent take-up assembly 4.

[0040] It should be noted that the center height of the cable guide 203 is consistent with the center height of the stranded cable drum 304.

[0041] The take-up assembly 4 includes a support frame 401 fixedly mounted on the top of the base plate 1. A take-up wheel 403 is rotatably mounted between the two support frames 401. A cycloidal frame 402 is fixedly mounted on one side of both support frames 401. A slide rail slider assembly is mounted on the top of the cycloidal frame 402. The slider is driven by a double-wire reciprocating screw rotatably mounted inside the cycloidal frame 402. A cycloidal rod 404 is mounted on the top of the slider to laterally pull the twisted cable, so that the cable is evenly distributed on the outside of the take-up wheel 403. The end of the double-wire reciprocating screw is driven by a pulley, and the rotation drive end of the take-up wheel 403 is driven by a motor pulley.

[0042] More often, the wire feeding reel in the wire feeding assembly needs to be disassembled and reassembled after wire feeding is completed. To achieve quick disassembly and assembly, such as... Figure 5 As shown, an electromagnetic actuator 2042 is installed inside one side wall of the pay-off frame 2041. A positioning rod 2043 is coaxially rotatably mounted on the output end of the electromagnetic actuator 2042, and the positioning rod 2043 can move axially along the movement direction of the output end of the electromagnetic actuator 2042. The end of the positioning rod 2043 away from the electromagnetic actuator 2042 is provided with a spline, which cooperates with the spline groove at the end of the pay-off wheel, so that the pay-off wheel and the positioning rod 2043 rotate synchronously. A positioning shaft is fixed on the other side of the pay-off frame 2041, and the positioning shaft cooperates with the end of the pay-off wheel and maintains a relative rotational state.

[0043] Similarly, such as Figure 6 As shown, similar to the structure in the unwinding assembly, an electromagnetic actuator 405 is installed inside one side wall of the support frame 401, and a positioning rod 406 is rotatably mounted at its output end. The end of the positioning rod 406 is splinedly engaged with the take-up reel 403. A transmission rod 407 is also rotatably mounted through the side wall of the support frame 401. The end of the transmission rod 407 near the take-up reel 403 is slidably engaged with the splined end of the positioning rod 406, and a pulley is coaxially mounted at the end of the transmission rod 407 away from the take-up reel 403 to transmit power.

[0044] In use, the cable to be twisted on each wire feeding wheel is pulled through between the two straightening wheels of the corresponding straightening wheel set 205, then through the wire threading sleeve 206 and around the fixed pulley 210 and the movable pulley 211. The cable to be twisted is then passed through the wire passing holes evenly opened on the wire passing reel 203. Multiple cables to be twisted converge at the twisting drum to complete the twisting and pass through the straightening wheel set 305. The twisted and straightened cable then passes through the ring on the cycloidal rod 404 and is finally fixed on the side wall of the take-up wheel 403.

[0045] The transmission gear 209 is driven by a motor to rotate, thereby driving the gear ring 208 to rotate, and the rotating disk 202 rotates synchronously. At the same time, the take-up reel 403 is driven by a motor to rotate, thereby pulling the cable.

[0046] The cable to be twisted on the wire feeding reel is fed out under traction. After being straightened, it passes through the wire threading sleeve 206, and then passes through the fixed pulley 210 and the movable pulley 211 for reversal and tensioning. After passing through the twisting drum 304, the cable is twisted. Then it is straightened and transported through the straightening component 305. Driven by the reciprocating cycloidal rod 404, the cable is wound on the take-up reel 403.

[0047] After the pay-off reel or take-up reel 403 finishes paying off or taking up the line, the electromagnetic actuator drives the positioning rod to move, thereby releasing the restriction on the pay-off reel or take-up reel 403, allowing the pay-off reel or take-up reel 403 to be disassembled and reinstalled. Then, the electromagnetic actuator drives the positioning rod back to the initial position, thus repositioning the pay-off reel or take-up reel 403.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
