[0002] A wire stranding machine is a kind of mechanical equipment that can be widely used in the stranding of various soft / hard conductor wires. It can twist multiple single conductors into one strand to meet the process requirements of the wire. Wire stranding machines can generally be divided into single stranding machines, pair stranding machines, high-speed stranding machines, back-twisting machines, cage stranding machines, frame stranding machines, tubular stranding machines and disc stranding machines according to the stranding method. The stranding machine for stranding cables is usually called a cable stranding machine.

[0003] When the wire twisting machine drives the winding drum to wind the cable, as the number of cable winding turns on the winding drum increases, the cable will gradually become tighter. When the tension of the cable is too tight, it is easy to cause damage to the cable. If the cable is set too loose at the beginning, it will affect the winding effect of the winding drum on the cable. For this reason, a wire twisting machine with adjustable tightness is provided. When the winding drum is winding the cable, the tightness of the cable can be automatically adjusted. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0023] Example 1

[0024] See also Figure 1 , Figure 3 , Figure 4 A wire twisting machine with adjustable tightness comprises a base 1 and a winding drum 2, wherein a support base 3 is fixedly arranged on the base 1, and the winding drum 2 is mounted on the support base 3. A pair of fixed frames 4 are symmetrically arranged on one side of the support base 3 of the base 1, and a reciprocating screw 5 and a guide rod 6 are installed between the two fixed frames 4. The reciprocating screw 5 is driven by a first motor arranged on one of the fixed frames 4, and a reciprocating moving member 7 adapted thereto is installed on the reciprocating screw 5, the guide rod 6 is fixedly arranged, and a sliding sleeve 8 is slidably arranged on the guide rod 6, the sliding sleeve 8 is connected to the reciprocating moving member 7 through a pair of round rods 9, and a movable ring 10 is arranged between the sliding sleeve 8 and the reciprocating moving member 7, and both sides of the outer ring diameter direction of the movable ring 10 A ring 11 is symmetrically fixedly arranged, and the ring 11 is movably installed on the round rod 9. The round rod 9 is located between the ring 11 and the reciprocating moving member 7. A spring 12 is also sleeved on the rod body of the round rod 9. By arranging the fixed frame 4, the reciprocating screw 5, the guide rod 6, the movable ring 10, the round rod 9 and the spring 12, in the process of the cable passing through the movable ring 10 and being wound on the winding drum 2, as the number of cable winding circles on the winding drum 2 increases, the movable ring 10 moves up and down between the two round rods 9, and cooperates with the spring 12 on the round rod 9 to automatically adjust the tightness of the cable. In addition, in the process of the reciprocating screw 5 driving the movable ring 10 to move back and forth horizontally, the cable can be evenly wound on the winding drum 2, thereby further improving the winding quality of the cable.

[0025] The inner wall of the ring 11 is also provided with a plurality of balls 13 in an array. The arrangement of the balls 13 reduces the friction resistance between the cable and the inner wall of the ring 11, which not only avoids the wear of the outer surface of the cable but also makes the cable winding smoother.

[0026] Example 2

[0027] This embodiment expands the functions based on the embodiment 1, specifically:

[0028] See also Figure 1 , Figure 2 and Figure 5 A triangular plate 14 is rotatably arranged on the support seat 3, and the triangular plate 14 is driven by a second motor arranged on the support seat 3, and three plug-in cylinders 15 are rotatably arranged on the side of the triangular plate 14, and the plug-in cylinder 15 is driven by a third motor arranged on the triangular plate 14, wherein the height of the plug-in cylinder 15 close to the side of the ring 11 is lower than the height of the ring 11, and the winding drum 2 is movably inserted in the plug-in cylinder 15 and fixed by a limiting assembly arranged on the plug-in cylinder 15. The arrangement of the triangular plate 14 and the three plug-in cylinders 15, after the cable winding on the winding drum 2 is completed, the rotation of the triangular plate 14 can be controlled to make another new winding drum rotate to the winding position, thereby realizing seamless connection of the winding drums, saving the replacement time of the winding drums, and improving the winding efficiency of the cables.

[0029] The limit assembly includes a bidirectional lead screw 16 rotatably arranged in the insert cylinder 15 and a plurality of cross bars 17 distributed outside the insert cylinder 15, wherein four cross bars 17 are arranged in an array outside the insert cylinder 15, the bidirectional lead screw 16 is driven by a servo motor arranged in the insert cylinder 15, and threaded sleeves 18 are symmetrically installed on the two threaded parts of the bidirectional lead screw 16, the threaded sleeves 18 are slidably arranged in the insert cylinder 15, and the threaded sleeves 18 are connected to the cross bars 17 through a connecting rod 19, wherein one end of the connecting rod 19 is hinged to the threaded sleeve 18, and the other end It is hinged with the cross bar 17, and the side wall of the insert cylinder 15 is also provided with a side hole for the connecting rod 19 to slide. Specifically, after the winding drum 2 is inserted into the insert cylinder 15, the servo motor is controlled to operate. When the servo motor drives the bidirectional lead screw 16 to rotate, the two threaded sleeves 18 are relatively close to each other. Under the transmission of the connecting rod 19, multiple cross bars 17 can be simultaneously moved away from the axis of the insert cylinder 15. The cross bars 17 are in contact with the inner wall of the winding drum, so that the winding drum can be fixed. Conversely, when the winding drum needs to be disassembled, it is only necessary to control the servo motor to rotate in the opposite direction to release the fixation of the winding drum.

[0030] Furthermore, after the winding disc is inserted into the inserting tube 15 , in order to ensure that the position of the winding disc is just within the moving range of the movable ring 10 , a limiting disc 20 is fixedly provided on the cylinder body of the inserting tube 15 on the side close to the triangular plate 14 in this embodiment.

[0031] Working principle: When the device is used to wind the cable, the cable is first passed through the movable ring 10 and fixed on the winding drum 2. While the winding drum 2 is driven to rotate, the first motor is controlled to operate at the same time. At this time, as the number of turns of the cable on the winding drum 2 increases, the movable ring 10 moves up and down between the two round rods 9. In conjunction with the spring 12 on the round rod 9, the tightness of the cable can be automatically adjusted. In addition, the reciprocating screw 5 drives the movable ring 10 to move back and forth horizontally, so that the cable can be evenly wound on the winding drum 2.

[0032] Furthermore, after the cable is wound on the winding drum 2, the triangle plate 14 can be controlled to rotate so that another new winding drum can be rotated to the winding position, thereby realizing seamless connection of the winding drums. The wound cable can be quickly disassembled and replaced by controlling the servo motor. Specifically, after the winding drum 2 is inserted into the insert cylinder 15, the servo motor is controlled to operate. When the servo motor drives the bidirectional lead screw 16 to rotate, the two threaded sleeves 18 are relatively close to each other. Under the transmission of the connecting rod 19, multiple cross bars 17 can be simultaneously moved away from the axis of the insert cylinder 15. The cross bars 17 contact the inner wall of the winding drum, thereby fixing the winding drum. Conversely, when the winding drum needs to be disassembled, the servo motor only needs to be controlled to rotate in the opposite direction to release the fixation of the winding drum.
