Description

Technical Field

[0002] Extrusion machines are crucial equipment in cable processing, primarily used to coat the wire core with polymer materials such as plastics and rubber to form an insulation or sheath layer. Rewinding equipment is an auxiliary device to the extrusion machine, capable of winding the processed cables into neat coils, ensuring they are evenly and tightly wound to meet subsequent storage, transportation, and processing needs. In existing technology, once the coil reaches a certain diameter, workers must cut the cable and glue the ends to the coil with adhesive tape to complete the winding process. This method of attaching cable ends with tape is cumbersome and inefficient for workers in winding the coils. Utility Model Content

[0033] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] refer to Figures 1 to 3 and Figure 5This utility model discloses a cable winding device, including a frame 100, a rotating shaft 110, a winding drum 200, a rotary drive device (not shown in the figure), and a first clamping device 300.

[0037] A rotating shaft 110 is rotatably connected to a frame 100, and the rotating shaft 110 is parallel to the left and right directions. A winding drum 200 includes a drum body 210 and two baffles 220, which are respectively connected to the two ends of the drum body 210. The drum body 210 is used to connect to the beginning of the cable, and the drum body 210 is detachably connected to the rotating shaft 110. A rotation drive device is provided on the frame 100, and the rotation drive device is used to drive the rotating shaft 110 to rotate so that the cable is wound on the drum body 210. A first clamping device 300 is provided on the baffle 220 away from the frame 100. A first threading hole 221 is provided on the baffle 220 away from the frame 100. The first threading hole 221 is away from the drum body 210 and is used for the end of the cable to pass through. The first clamping device 300 is used to clamp the end of the cable.

[0038] In this embodiment of the invention, the cable winding device is positioned in front of the extruder. The cable extruded by the extruder moves from back to front, allowing the cable winding device to wind the cable. The rotating shaft 110 can be a common expansion roller. When the winding drum 200 needs to be mounted on the expansion roller, the worker can place the drum body 210 of the winding drum 200 onto the expansion roller and inflate the expansion roller, thus tightening the drum body 210 of the winding drum 200. At this time, the drum body 210 of the winding drum 200 is fixedly connected to the expansion roller. When the drum body 210 of the winding drum 200 needs to be removed from the expansion roller, the expansion roller retracts, allowing the worker to pull the drum body 210 out of the expansion roller to complete the disassembly of the drum body 210. Further details are omitted here.

[0039] Understandably, when it is necessary to wind up the cable, the worker can install the winding drum 200 on the rotating shaft 110 and connect the cable end to the drum body 210 of the winding drum 200. After the cable end is installed, the worker can start the rotary drive device, which drives the rotating shaft 110 to rotate, thereby causing the rotating shaft 110 to rotate the winding drum 200. After the winding drum 200 starts to rotate, the cable is wound around the drum body 210 of the winding drum 200 to complete the winding of the cable. When the diameter of the cable roll on the winding drum 200 reaches the preset diameter, the worker cuts the cable and passes the cable end through the first threading hole 221 on the baffle 220 in the winding drum 200. After the cable end protrudes from the first threading hole 221, the worker can operate the first clamping device 300 to clamp the cable end to fix the cable end and complete the winding. The first clamping device 300 in this cable winding equipment can clamp the end of the cable, replacing the cumbersome tape bonding method and shortening the operation time of winding the cable. Therefore, it helps to improve the efficiency of workers in winding the cable.

[0040] refer to Figure 3 and Figure 6 The first clamping device 300 includes a first clamping block 310, a second clamping block 320, and a fixing assembly. The first clamping block 310 is disposed on a baffle 220 away from the frame 100. The second clamping block 320 is movably connected to the first clamping block 310. The gap between the first clamping block 310 and the second clamping block 320 is used for the cable end to pass through. The second clamping block 320 can be brought close to and fixed to the first clamping block 310 by the fixing assembly, so that the first clamping block 310 and the second clamping block 320 clamp the cable end. The fixing assembly includes two fasteners 330. The first clamping block 310 has two threaded holes, and the second clamping block 320 has two through holes. The two fasteners 330 are respectively inserted into the two through holes and are threadedly connected to the inner walls of the two threaded holes. The area between the two fasteners 330 is used for the cable end to pass through. The fixing assembly also includes two elastic elements 340. The first clamping block 310 is provided with two mounting grooves, and two threaded holes are respectively opened on the inner bottom wall of the two mounting grooves. The two elastic elements 340 are respectively sleeved on the two fasteners 330. One end of the two elastic elements 340 abuts against the inner bottom wall of the two mounting grooves, and the other end of the two elastic elements 340 abuts against the second clamping block 320. Both elastic elements 340 are used to drive the second clamping block 320 away from the first clamping block 310.

[0041] In this embodiment of the invention, the fastener 330 is a bolt with a gripping portion at its large end, and the elastic element 340 is a compression spring. The gap between the first clamping block 310 and the second clamping block 320 communicates with the first threading hole 221. Under the upward pushing action of the two compression springs, the second clamping block 320 can maintain contact with the large ends of the two bolts. After the worker cuts the cable, the end of the cable can be passed through the first threading hole 221 and placed in the gap between the first clamping block 310 and the second clamping block 320. Then, the worker can tighten the two bolts, causing the large ends of the two bolts to push the second clamping block 320 downward, thereby bringing the second clamping block 320 closer to the first clamping block 310, and the two compression springs begin to compress. As the two bolts continue to tighten, the second clamping block 320 can press the end of the cable against the first clamping block 310, so that the first clamping block 310 and the second clamping block 320 clamp the end of the cable, thus completing the clamping of the cable end. When it is necessary to loosen the end of the cable, the worker can loosen the two bolts. At this time, the two compression springs begin to extend and push the second clamping block 320 upward, so that the second clamping block 320 can abut against the large ends of the two bolts, thereby moving the second clamping block 320 away from the first clamping block 310 and loosening the end of the cable. The first clamping block 310 is provided with two mounting grooves, which are used to accommodate the two compression springs respectively. After the first clamping block 310 and the second clamping block 320 have completed clamping the end of the cable, the two compression springs in a compressed state can enter the two receiving grooves respectively, so that the second clamping block 320 can smoothly approach the first clamping block 310. As an embodiment of this utility model, rubber pads are provided on the sides of the first clamping block 310 and the second clamping block 320 that are close to each other, and the first clamping block 310 and the second clamping block 320 clamp the end of the cable through the rubber pads. Understandably, the rubber pads are made of elastic material. The first clamp 310 abuts against the end of the cable through the rubber pads, and the second clamp 320 abuts against the end of the cable through the rubber pads, so as to reduce the damage to the end of the cable by the first clamp 310 and the second clamp 320.

[0042] refer to Figure 6 The first clamping block 310 has two limiting blocks 350, and the second clamping block 320 has two clearance grooves 360. The two limiting blocks 350 can be respectively inserted into the two clearance grooves 360. The area between the two limiting blocks 350 is connected to the first wire-passing hole 221, and the area between the two limiting blocks 350 is used for the cable end to pass through. It can be understood that after a worker cuts the cable and passes the cable end through the first wire-passing hole 221, the cable end can pass through the area between the two limiting blocks 350. The two limiting blocks 350 can guide the cable end, allowing it to accurately stop between the first clamping block 310 and the second clamping block 320, thus enabling the first clamping block 310 and the second clamping block 320 to smoothly clamp the cable end.

[0043] refer to Figure 4 The cable winding equipment also includes a second clamping device 400, located on a baffle 220 away from the frame 100. A second threading hole is provided on the baffle 220, which is close to the cylinder 210. The second threading hole is used for the cable's head end to pass through, and the second clamping device 400 is used to clamp the cable's head end. Understandably, when the cable needs to be wound, the worker can install the winding drum 200 on the rotating shaft 110 and pass the cable's head end through the second threading hole on the baffle 220 in the winding drum 200. After the cable's head end extends from the second threading hole, the worker can operate the second clamping device 400 to clamp the cable's head end, thus fixing it in place. Then, the worker can activate the rotary drive device, causing the rotating shaft 110 to rotate, which in turn causes the winding drum 200 to rotate and wind the cable onto the cylinder 210, thus completing the cable winding. The worker can operate the second clamping device 400 to quickly fix the cable end, shortening the operation time for fixing the cable end. The second clamping device 400 has the same structure as the first clamping device 300, and will not be described further here.

[0044] refer to Figure 2 , Figure 3 and Figure 8The cable winding device also includes a handwheel 120. One end of the rotating shaft 110 is provided with a screw (not shown in the figure), and the other end of the rotating shaft 110 is provided with a support protrusion 111. The support protrusion 111 abuts against the winding drum 200. The handwheel 120 is threadedly connected to the screw and pressed against the winding drum 200. Understandably, when the winding drum 200 needs to be installed on the rotating shaft 110, the worker can sleeve the drum body 210 of the winding drum 200 onto the rotating shaft 110, so that one of the baffles 220 of the winding drum 200 abuts against the support protrusion 111 on the rotating shaft 110. Then, the worker can thread the handwheel 120 to the screw on the rotating shaft 110 and tighten the handwheel 120, so that the handwheel 120 presses against the other baffle 220 of the winding drum 200, thereby pressing one of the baffles 220 of the winding drum 200 against the support protrusion 111. At this point, the handwheel 120 and the support protrusion 111 clamp the take-up drum 200, thus fixing the take-up drum 200 onto the rotating shaft 110, completing the installation of the drum body 210. After the yarn wound on the drum body 210 of the take-up drum 200 reaches the preset diameter, the worker can stop the rotary drive and finish winding the yarn. After finishing winding the yarn, the worker can loosen the handwheel 120 and remove it from the rotating shaft 110. Then, the worker can remove the take-up drum 200 and the yarn on it from the rotating shaft 110 to complete the disassembly of the drum body 210, so as to replace it with the next empty take-up drum 200. Further details are omitted here. Specifically, in this embodiment of the present invention, the body 210 of the take-up drum 200 is sleeved on the rotating shaft 110. The baffle 220 of the take-up drum 200 away from the frame 100 is provided with a first threading hole 221, a second threading hole, a first clamping device 300 and a second clamping device 400. The handwheel 120 is pressed against the baffle 220 of the take-up drum 200 away from the frame 100. The baffle 220 of the take-up drum 200 close to the frame 100 abuts against the support protrusion 111. Further details are omitted here.

[0045] refer to Figure 1 and Figure 7The cable winding equipment also includes an auxiliary winding device 500, which is mounted on the frame 100 and located above the rotating shaft 110. The auxiliary winding device 500 is used to wind the cable and drive the cable to reciprocate in the left-right direction. In this embodiment of the invention, the rotating shaft 110 is parallel to the left-right direction. During the process of the cable winding on the cylinder 210, the auxiliary winding device 500 can drive the cable to reciprocate in the left-right direction, so that the cable can be evenly wound on the cylinder 210. The auxiliary winding device 500 includes a winding wheel 510 and a linear drive mechanism 520. The linear drive mechanism 520 is mounted on the frame 100, and the winding wheel 510 is rotatably connected to the output end of the linear drive mechanism 520. The outer wall of the winding wheel 510 is provided with a limiting ring groove 511, the inner bottom wall of the limiting ring groove 511 is used for winding the cable, and the linear drive mechanism 520 is used to drive the winding wheel 510 to reciprocate in the left-right direction. Understandably, the cable is wound within the limiting annular groove 511 on the outer wall of the winding wheel 510. The inner wall of the limiting annular groove 511 can limit the cable to prevent it from coming off the winding wheel 510. During the rotation of the take-up drum 200 to wind the cable, the linear drive mechanism 520 can drive the winding wheel 510 to reciprocate in the left-right direction, causing the winding wheel 510 to move the cable reciprocally in the left-right direction, thus ensuring the cable is evenly wound around the drum body 210 of the take-up drum 200. Specifically, the linear drive mechanism 520 can be a cylinder and a connecting rod. The connecting rod is parallel to the left-right direction. The cylinder body is connected to the frame 100, and the piston rod of the cylinder is connected to one end of the connecting rod. The winding wheel 510 is rotatably connected to the other end of the connecting rod. The cylinder can drive the connecting rod to reciprocate in the left-right direction, thus causing the winding wheel 510 to reciprocate in the left-right direction. The linear drive mechanism 520 can also be a common lead screw and nut drive mechanism, which will not be elaborated further here.

[0046] In this embodiment of the utility model, reference is made to Figure 1The cable winding device includes two rotating shafts 110, both for mounting winding drums 200. The rotary drive includes two motors mounted on a frame 100, each driving one of the rotating shafts 110 to rotate. The auxiliary winding device 500 includes a linear drive mechanism 520 and two winding wheels 510. Both winding wheels 510 are rotatably connected to the output end of the linear drive mechanism 520. The two winding wheels 510 are located above the two rotating shafts 110. The linear drive mechanism 520 drives the two winding wheels 510 to reciprocate simultaneously in the left-right direction. In actual use, only one motor drives the rotating shaft 110 to rotate, ensuring that only the winding drum 200 on one rotating shaft 110 winds the cable, while the other rotating shaft 110 remains stationary, and the other winding drum 200 is idle. When the cable on the take-up spool 200 reaches the preset diameter, the worker finishes the cable winding and connects the cable end to another empty take-up spool 200, allowing the empty take-up spool 200 to continue winding the cable. The worker then removes the finished take-up spool 200 from the spindle 110 and installs an empty take-up spool 200, and so on, allowing the two take-up spools 110 to alternately wind the cable. This method of using two spindles 110 to alternately wind the cable is a common setup in the cable winding industry and will not be elaborated further here.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
