Description

Technical Field

[0001] The invention relates to the field of wire twisting machines, in particular to a multifunctional wire twisting machine. Background Art

[0002] Wire twisting machine is a kind of mechanical equipment that can be widely used in various soft / hard conductor wires to twist multiple single conductors into one strand to meet the process requirements of wires. Wire twisting machine can be generally divided into single twisting machine, pair twisting machine, high-speed twisting machine, back-twisting machine, cage twisting machine, frame twisting machine, tubular twisting machine and disc twisting machine according to the twisting method. Wire twisting machine is a kind of mechanical equipment that can be widely used in various soft / hard conductor wires (copper wire, enameled wire, tinned wire, copper clad steel, copper clad aluminum, etc.) and electronic wires such as power cord, headphone wire, telephone wire, PVC wire, network wire, etc., to twist multiple single conductors into one strand to meet the process requirements of wires.

[0003] However, the traditional wire twisting machine still has some shortcomings when in use. The traditional wire twisting machine uses a gear box to drive the basket frame to achieve the purpose of twisting the wire, and the angle adjustment of the basket frame is limited. There are also defects such as high noise, low efficiency and unstable operation. At the same time, most wire twisting machines need to frequently replace new wire reels when in use. When replacing, it is necessary to loosen the locking screw with a wrench and manually release the latch safety lock, which makes replacement inconvenient. When the traction device transports the stranded wire to the wire leveler, the stranded wire will be tightened due to excessive tension or loosened due to insufficient tension. Excessive tension will cause the stranded wire to break, and too little tension will cause the stranded wire to be unevenly distributed. Whether the tension is too high or too low, it will affect the normal operation of the wire twisting machine.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0027] The following describes the specific embodiments of the present invention in conjunction with the accompanying drawings. Figure 1 as well as Figure 2 ,in, Figure 1 It is a structural schematic diagram of a multifunctional wire stranding machine of the present invention; Figure 2 It is a partial structural schematic diagram of a multifunctional wire twisting machine of the present invention.

[0028] like Figure 1-2As shown, a multifunctional stranding machine includes a main frame 5, an inner shaft 13 and a main motor 17, a transmission shaft 21 is arranged below the main motor 17, wherein the transmission shaft 21 is connected to the main motor 17 through a main motor synchronous pulley 19 and a transmission shaft synchronous pulley b20, a continuously variable transmission gearbox 1 is arranged below the transmission shaft 21, and the front end of the continuously variable transmission gearbox 1 is connected to the transmission shaft synchronous pulley a18 through a large continuously variable transmission gearbox synchronous pulley 12, the other end of the continuously variable transmission gearbox 1 is connected to a continuously variable transmission gearbox pinion 2, and the continuously variable transmission gearbox pinion 2 is connected to the inner shaft transmission gear 3 at the front end of the inner shaft 13, wherein the inner shaft 13 is arranged on the main frame 5; an outer shaft 9 is arranged on the outer side of the inner shaft 13, and the outer shaft An electromagnetic clutch 7 is also provided on the outside of the outer shaft 9 and on one side of the inner shaft transmission gear 3, and two groups of main shaft large bearings 8 are also provided on the outside of the outer shaft 9 and on one side of the electromagnetic clutch 7, wherein a brake disc 6 is provided between the two groups of main shaft large bearings 8, and an inner shaft bearing 10 is provided on the inside of the outer shaft 9 and at the rear end of the inner shaft 13, wherein an inner shaft gear 11 is provided on one side of the inner shaft bearing 10, and a bridge gear 14 is provided on the outside of the inner shaft gear 11, and the outer end of the bridge gear 14 is connected to a back-twist gear 15, and one side of the back-twist gear 15 is connected to a basket 16; a front capstan 28 is provided on the outside of the outer shaft 9, and one side of the basket 16 is also movably connected to a basket bearing 27 provided on the front capstan 28 through the back-twist gear 15.

[0029] A butterfly brake 4 is arranged on the outer side of the brake disc 6 , and the butterfly brake 4 is fixed on the main frame 5 .

[0030] A bearing seat 23 is arranged above the two sets of main shaft large bearings 8, the end of the transmission shaft 21 is movably connected to the bearing seat 23, and a transmission shaft synchronous pulley c24 is arranged between the two bearing seats 23, and the transmission shaft synchronous pulley c24 is transmission-connected to the outer shaft synchronous pulley 25 outside the outer shaft 9.

[0031] Working principle:

[0032] This device is divided into two branches. One is transmitted to the transmission shaft synchronous pulley b20 through the main motor 17 and then transmitted to the outer shaft synchronous pulley 25 through the transmission shaft synchronous pulley c23, driving the outer shaft 9 to rotate, and transmitting to the front capstan 28, thereby driving the basket 16 to work; the other is transmitted to the stepless transmission gearbox 1 through the transmission shaft synchronous pulley a18, and then transmitted to the main capstan inner shaft transmission gear 3 through the stepless transmission gearbox pinion 2, thereby driving the inner shaft 13 to transmit, and then the inner shaft 13 is transmitted to the inner shaft gear 11, and further transmitted to the bridge gear 14 and the back-twist gear 15, thereby further meeting the requirements of different differential coefficients;

[0033] In order to achieve the goal of the basket 16 and the main strand to rotate in a horizontal state, the electromagnetic clutch 7 is installed on the main frame 5 and the transmission gear of the inner shaft 3 respectively. When the basket 16 and the strand are required to operate in a horizontal state, the electromagnetic clutch 7 remains in the engaged state and the stepless transmission 1 remains in the neutral state.

[0034] When the basket 16 is required to adjust the angle during operation, the electromagnetic clutch 7 remains disengaged, and the electromagnetic clutch 7 is disengaged by installing an elastic bushing 22 on the inner shaft 13. The basket 16 can be adjusted at any angle according to the cable manufacturing process. At the same time, in order to facilitate the loading and unloading of the cable reel, the reel can be guaranteed to be 90 degrees or 180 degrees at the same time. The whole machine can be loaded and unloaded, and the electric loading and unloading reel trolley can also be used to load and unload the cable reel separately;

[0035] The inner shaft 13 drives the gear set through the electromagnetic clutch 7 fixed on the frame. The electromagnetic clutch 7 is engaged, the inner shaft 13 does not rotate, and the front capstan 28 and the basket 16 run together. The front capstan 28 and the basket 16 remain in the same state if the basket is in a horizontal state. If pre-twisting is required, the electromagnetic clutch 7 can be disengaged, because the rotation speed can be adjusted to make the rotation speeds of the inner shaft 13 and the outer shaft 9 different, so that the basket 16 can be deflected at an angle, the torque of the cable is twisted back, and then the electromagnetic clutch 7 is engaged. Keep the front capstan 28 and the basket 16 running together. Disengaging the clutch can also make the rotation speeds of the capstan and the basket different, and can be adjusted arbitrarily according to the requirements of cable manufacturing.

[0036] This solution can also achieve the functions of cable taping and armoring for the main engine at the same time. It can be arranged in multiple motor units or arranged in intervals. Through the drive of each motor and PLC operation, the cable twisting and taping and armoring can be integrated.

[0037] This case also provides constant tension control for the basket. The unwinding tension is controlled by a magnetic powder clutch. The tension can be set, displayed and modified. The tension is automatically calculated by Siemens PLC to control the speed of each motor to ensure accurate and stable pitch. It automatically tracks the diameter of the wire drum to ensure that the tension is consistent from the full wire drum to the empty wire drum, ensuring uniform and constant tension.
