Description

Technical Field

[0001] This utility model relates to the field of wire and cable production technology, and in particular to a stranding machine for wire and cable production. Background Technology

[0002] A stranding machine is a widely used mechanical device for stranding various soft / hard conductor wires, turning multiple single conductors into a single strand to meet the processing requirements of the wire. Stranding machines can generally be classified according to the stranding method into single stranding machines, pair stranding machines, high-speed stranding machines, untwisting machines, cage stranding machines, frame stranding machines, tubular stranding machines, and disc stranding machines, etc. Stranding machines are required in the production of wires and cables.

[0003] Announcement No. (CN221668578U) discloses a stranding device for wire and cable production. When the spool needs to be replaced, a stepper motor drives a screw to rotate via a second bearing seat. The rotation of the screw causes a threaded block to move to the left, which in turn causes a support wheel to move. Simultaneously, the threaded block causes a fixed column to move to the left, which in turn causes a support beam to move. The support beam then causes a mounting plate to move to the left, which in turn causes the first bearing seat to move to the left, separating the first bearing seat from the rotating shaft. The spool is then removed from the surface of the rotating shaft. When installing the spool, the above steps are reversed. However, the spool containing cable is quite heavy, making replacement difficult and requiring improvement. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-7 As shown, a stranding machine for producing wires and cables includes a feeding mechanism 1 for placing a winding roller with wires wound on the ground, and a drive mechanism 2 for driving the winding roller to rotate is installed on the feeding mechanism 1.

[0029] In this utility model, the unloading mechanism 1 includes a base plate 101, a fixing frame 102 is mounted on the upper surface of the base plate 101, and a hydraulic cylinder 103 is arranged above the fixing frame 102. There are two hydraulic cylinders 103, and the telescopic ends of both hydraulic cylinders 103 penetrate the fixing frame 102. A lifting box 104 is fixed to the telescopic ends of the two hydraulic cylinders 103. Lifting frames 105 are fixedly mounted on both side walls of the lifting box 104. A first motor 106 is mounted on the lower surface of the lifting box 104, and the output end of the first motor 106 penetrates the lifting box 104. A gear 107 located inside the lifting box 104 is connected to the output end of the first motor 106. 07 A rack 108 meshes with the front and rear of the gear. A movable rod 109 is fixedly installed at one end of the rack 108. A movable plate 110 is fixed on the lower surface of the movable rod 109. A limit seat 111 is fixed on one side of the movable plate 110. A take-up roller body 113 is arranged between the two movable plates 110. Two rotating shafts 112 are fixed on the take-up roller body 113. An opening that mates with the take-up roller body 113 is opened on the bottom plate 101. Sliding grooves that mate with the lifting frame 105 are opened on both sides of the fixed frame 102. The lifting frame 105 is slidably connected to the fixed frame 102. The front and rear surfaces of the lifting box 104 are provided with... A sliding groove mates with the movable rod 109, which is slidably connected to the lifting box 104. A sliding groove mates with the movable plate 110 on the lower surface of the lifting box 104, which is slidably connected to the lifting box 104. When using the device, the rotating shafts 112 on both sides of the take-up roller body 113 are placed on the movable plate 110, with the corresponding rotating shafts 112 tightly against the limiting seat 111. Then, the driving device drives the rotating shafts 112 to rotate, which in turn drives the take-up roller body 113 to rotate. The take-up roller body 113 rotates to wind up the cable. After winding is complete, the hydraulic cylinder 103 is activated, and the hydraulic cylinder 103 drives... The lifting box 104 and the lifting frame 105 descend, and the movable plate 110 descends accordingly. The movable plate 110 drives the rotating shaft 112 and the take-up roller body 113 to descend. When the take-up roller body 113 descends and contacts the ground, the first motor 106 is started. The operation of the first motor 106 drives the gear 107 to rotate. The rotation of the gear 107 drives the rack 108 to move. The rack 108 drives the movable rod 109 and the movable plate 110 to move. The two movable plates 110, which are far apart from each other, separate from the rotating shaft 112. By adopting the above method, the automatic unloading of the take-up roller body 113 can be realized, thereby making the replacement of the take-up roller body 113 easy.

[0030] In this utility model, the drive mechanism 2 includes two electric push rods 201 mounted on the side wall of the fixed frame 102. A movable frame 202 is fixed to the telescopic end of each of the two electric push rods 201. The movable frame 202 passes through the fixed frame 102 and is slidably connected to the fixed frame 102. A movable shell 203 is fixed on the movable frame 202. A second motor 204 is fixed to the side wall of the movable shell 203. A rotating platform 205 is connected to the output end of the second motor 204. The rotating platform 205 is rotatably connected to the movable shell 203. The side of the rotating platform 205 away from the second motor 204 is fixed. An electric chuck 206 is provided. After the take-up roller body 113 is placed, the electric push rod 201 is activated. The electric push rod 201 retracts, causing the movable frame 202 and movable shell 203 to move. The movable shell 203 causes the electric chuck 206 to move. The electric chuck 206 moves and contacts the rotating shaft 112. Then, the electric chuck 206 is activated to fix the rotating shaft 112. The second motor 204 is then activated. The second motor 204 runs, causing the rotating table 205 and the electric chuck 206 to rotate. The electric chuck 206 causes the rotating shaft 112 and the take-up roller body 113 to rotate. The take-up roller body 113 rotates to wind up the cable.

[0031] In the above structure: When using the device, place the rotating shafts 112 on both sides of the take-up roller body 113 on the movable plate 110 and make the corresponding rotating shafts 112 tightly against the limiting seat 111. Start the electric push rod 201. The electric push rod 201 retracts, driving the movable frame 202 and the movable shell 203 to move. The movable shell 203 drives the electric chuck 206 to move. The electric chuck 206 moves and contacts the rotating shaft 112. Then, start the electric chuck 206 to fix the rotating shaft 112. Then start the second motor 204. The second motor 204 runs, driving the rotating table 205 and the electric chuck 206 to rotate. The electric chuck 206 drives the rotating shaft 112 and the take-up roller body 113 to rotate. The rotation of the take-up roller body 113 moves the cable. After the cable is wound up, the electric chuck 206 is released from fixing the rotating shaft 112 and returns it to its original position. The hydraulic cylinder 103 is started, and the operation of the hydraulic cylinder 103 drives the lifting box 104 and the lifting frame 105 to descend. The movable plate 110 descends accordingly. The movable plate 110 drives the rotating shaft 112 and the winding roller body 113 to descend. The winding roller body 113 descends and contacts the ground. Then the first motor 106 is started. The operation of the first motor 106 drives the gear 107 to rotate. The rotation of the gear 107 drives the rack 108 to move. The rack 108 drives the movable rod 109 and the movable plate 110 to move. The two movable plates 110, which are far apart from each other, separate from the rotating shaft 112. In this way, the automatic unloading of the winding roller body 113 is realized.
