Description

Technical Field

[0001] The utility model relates to the technical field of twisting machines, and more specifically, to a twisting machine for producing network box wires. Background Art

[0002] A pair twisting machine is also called a twisting machine. It is a wire and cable equipment used for twisting high-frequency data cables, so that multiple single conductors are twisted into one strand to meet the process requirements of the wire.

[0003] When installing the take-up drum and the twisting machine, the take-up drum needs to be installed through a fixing block and a large number of fixing bolts. This installation method increases the installation burden of the workers, and during the installation process, the machine can only be stopped to wait for the replacement to be completed before the next round of twisting can be carried out, resulting in low processing efficiency.

[0004] Therefore, a solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a twisting machine for network box cable production, in which movable mounting rods are arranged on both sides of a rotating rod to disassemble and assemble the take-up reel, and the take-up reel can be quickly disassembled and assembled by a driving device and a limit block, and the take-up station can also be replaced, so that the twisting machine can perform continuous processing, thereby improving the working efficiency of the twisting machine.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a twisting machine for network box cable production, comprising a frame and a wire-taking mechanism installed on the frame, the wire-taking mechanism comprising a rotating rod rotatably connected to the frame, two symmetrically distributed cross bars are fixedly connected to the side walls of the rotating rod, and mounting rods for sleeve-mounted wire-taking reels are arranged on the cross bars on both sides, the mounting rods are slidably connected to the cross bars, and a moving mechanism for driving the mounting rod to move is arranged on the cross bars, an extension rod is fixedly connected to the lower end face of the mounting rod, and a plurality of limit blocks distributed in a ring array are arranged on the outer wall of the extension rod, and a driving device for driving the limit blocks to extend and retract is arranged in the extension rod.

[0007] By adopting the above technical solution, the wire take-up drum is sleeved on the outside of the mounting rod, and then the limiting block on the extension rod is driven to extend outward by the driving device, so that the upper end surface of the limiting block abuts against the bottom surface of the wire take-up drum, and the wire take-up drum can be fixed on the mounting rod and cannot fall out anymore. At this time, the mounting rod is rotated, and the wire take-up drum can take up the twisted wire. When the wire take-up drum is finished and needs to be replaced for unloading, the rotating rod is first rotated to drive the cross bar to rotate, and the wire take-up drum installed in the same way on the cross bar on the other side is used for taking up the wire, and the wire take-up drum that needs to be unloaded will rotate to the side close to the conveyor belt, and then the mounting rod is driven by the moving mechanism The mounting rod moves outward, so that the take-up reel with completed wire winding comes to the top of the conveyor belt, and then the limit block is retracted through the driving device. After there is no obstruction of the limit block, the take-up reel can be taken out from the bottom, and the take-up reel will fall onto the conveyor belt for transmission and unloading. The operator then puts the empty mounting rod on the new take-up reel, re-extends the limit block for limiting, and then moves the mounting rod back to its original position. After the take-up reel on the processing position has completed winding, the rotating rod is rotated again to exchange the positions of the take-up reels on the cross bars on both sides. This reciprocating process makes the disassembly and assembly of the take-up reel more convenient and efficient, and makes the continuity of the twisting machine processing process better, thereby improving the twisting efficiency of the network box cable.

[0008] The utility model is further configured as follows: the driving device includes a cavity one arranged in the extension rod and a cavity two arranged in the mounting rod, the cavity two is communicated with the cavity one, a telescopic rod with one end fixedly connected thereto is arranged in the cavity two, the other end of the telescopic rod is fixedly connected to a conical block, a plurality of the limit blocks are fixedly connected to a connecting rod on one side close to the extension rod, a through hole for inserting the connecting rod is arranged on the inner wall of the cavity one, a plurality of the extension rods are fixedly connected to one end inserted into the cavity one with a resistance plate, and an extrusion channel for passing the conical block is formed between the plurality of resistance plates.

[0009] By adopting the above technical solution, when it is necessary to change the position of the limit block through the driving device, the conical block is driven to move by the extension and retraction of the telescopic rod. When the telescopic rod is extended, the part with a larger cross-sectional diameter of the conical block will be inserted into the extrusion channel, and the contact plate will be squeezed outward by the conical block. The contact plate can drive the limit block to move to the side away from the conical block through the connecting rod, and the limit block can move outward to abut against the bottom surface of the take-up drum to fix the take-up drum. When the telescopic rod is shortened, the part with a smaller cross-sectional diameter of the conical block will be located in the extrusion channel. Without the extrusion of the conical block, the contact plate can gather inward, and the limit block can also retract, so that the take-up drum can be removed from the mounting rod, and the operation is convenient and efficient.

[0010] The utility model is further configured as follows: an elastic member is arranged between the abutment plate and the inner wall of the first cavity, and the abutment plate is always in contact with the surface of the conical block.

[0011] By adopting the above technical solution, the elastic member is a spring, and the two ends of the elastic member are fixedly connected to the inner wall of the cavity and the contact plate respectively. When the elastic member is in the initial state, the contact plate can contact the part with the smallest cross-sectional diameter of the conical block. In this way, when the telescopic rod is shortened, the rebound force of the elastic member can cause the contact plate and the limit block to retract and gather quickly.

[0012] The utility model is further configured as follows: the moving mechanism includes a receiving groove arranged on the cross bar, a screw rod rotatably connected to the receiving groove is arranged in the receiving groove, a driving member for driving the screw rod to rotate is installed on the cross bar, a nut seat is sleeved on the screw rod, and the mounting rod is rotatably connected to the nut seat.

[0013] By adopting the above technical solution, when the mounting rod needs to be moved, the lead screw is driven to rotate by the driving member, and the forward and reverse rotation of the lead screw can drive the nut seat to reciprocate along the lead screw, and the nut seat can drive the mounting rod to move. After moving to the appropriate position, the rotation of the lead screw can be stopped. When the wire take-up drum is fixed on the outside of the mounting rod, the two ends of the wire take-up drum are respectively abutted against the lower end surface of the nut seat and the upper end surface of the limit block, so that the fixation of the wire take-up drum is more stable.

[0014] The utility model is further configured as follows: a limiting rod is fixedly connected to the inner wall of the accommodating groove, and a limiting groove for the limiting rod to pass through is arranged on the nut seat.

[0015] By adopting the above technical solution, when the nut seat moves with the rotation of the screw rod, the nut seat will move along the limit rod, making the nut seat more stable during the movement and preventing the nut seat from rotating with the screw rod.

[0016] The utility model is further configured as follows: an end of the abutment plate close to the telescopic rod is fixedly connected with an expansion plate.

[0017] By adopting the above technical solution, the expansion plate makes the opening of the extrusion channel closer to the end of the telescopic rod larger, so that the tapered block can be inserted into the extrusion channel more smoothly.

[0018] The utility model is further configured as follows: the driving member is a motor, and the output shaft of the motor is drivingly connected to one end of the screw rod.

[0019] In summary, the utility model has the following beneficial effects:

[0020] The utility model provides movable installation rods on both sides of the rotating rod to disassemble and assemble the wire take-up drum. The wire take-up drum can be quickly disassembled and assembled by the driving device and the limit block, and the wire take-up station can be replaced, so that the twisting machine can perform continuous processing, thereby improving the working efficiency of the twisting machine.

[0034] The wire take-up drum 19 is sleeved on the outside of the mounting rod 4, and then the limiting block 6 on the extension rod 5 is extended outward by the driving device, so that the upper end surface of the limiting block 6 abuts against the bottom surface of the wire take-up drum 19, and the wire take-up drum 19 can be fixed on the mounting rod 4 and cannot be slipped out. At this time, the mounting rod 4 is rotated, and the wire take-up drum 19 can take up the twisted wire. When the wire take-up drum 19 is finished and needs to be replaced and unloaded, the rotating rod 2 is first rotated to drive the cross bar 3 to rotate, and the wire take-up drum 19 installed in the same way on the cross bar 3 on the other side is used for taking up the wire, and the wire take-up drum 19 that needs to be unloaded will rotate to the side close to the conveyor belt, and the mounting rod 4 is driven outward by the moving mechanism at this time.
