Description

Technical Field

[0001] The invention relates to the technical field of cable and wire winding, in particular to a cable and wire winding machine with adjustable tension. Background Art

[0002] Wires and cables refer to materials used for power, electrical and related transmission purposes. There is no strict boundary between "wires" and "cables". Usually, products with a small number of cores, small product diameter and simple structure are called wires, those without insulation are called bare wires, and others are called cables.

[0003] As for the winding and packaging involved at the end of the cable and wire production process, the cable end needs to be fixed on the material roller through the guide. While the material roller rotates, the guide drives the cable to move left and right regularly, so that the cable is evenly wound on the material roller. As mentioned in the invention patent with publication number CN116022598A, the first chain can drive the vertical block to reciprocate in the horizontal direction through the fixed column, and the vertical block drives the limit ring to reciprocate. The reciprocating motion of the limit ring can make the cable passing through it evenly reeled on the surface of the cable roller, realizing the function of evenly reeling the cable. The limit ring here is equivalent to the cable guiding mechanism, but there are certain problems in moving the limit ring by driving the chain:

[0004] Since the left and right moving speed of the limit ring is reduced at the rotation points on both sides of the sprocket, the residence time of the limit ring on both sides of the cable roller increases, resulting in an increase in the winding thickness of the cable on both sides of the cable roller, and the overall winding is uneven. At the same time, the left and right moving range of the entire limit ring cannot be adjusted according to the length of the cable roller, and the adaptation range of the cable guide is low;

[0005] At the same time, when the cable is wound, the winding tension needs to be adjusted to prevent the cable from loosening and falling off the wire roller after winding, or the cable from being wound and compressed due to looseness, which is not conducive to the subsequent use of the wire roller with the cable;

[0006] For this purpose, we propose a cable and wire winding machine with adjustable tension. Summary of the invention

[0009] The top inner wall of the movable frame is symmetrically fixed with fixing grooves by spot welding, and a groove plate is movably connected to one side of the two fixing grooves and located on the top inner wall of the movable frame.

[0010] Furthermore, a side baffle is fixed to the top of the limit block by spot welding, and top blocks are slidably connected on both sides of the limit block. Locking bolts are symmetrically installed on the top of the limit block, and one end of the locking bolt passes through one side of the top of the limit block and abuts against a side cut surface of the top block.

[0011] Furthermore, the sliding mechanism includes a sliding sleeve, a clamping sleeve, a rotating block and a clamping block. The outer wall of the sliding rod is slidably connected to the sliding sleeve, the top of the sliding sleeve is fixed with a clamping sleeve by spot welding, one side of the sliding sleeve is rotatably connected to the rotating block, and a limiting column is fixedly connected to the rotating block, and limiting bolts are symmetrically fixed on the sliding sleeve and on both sides of the rotating block by spot welding, one side of the sliding sleeve is rotatably connected to the clamping block, and the clamping block is clamped with the outer wall of the worm, one side of the clamping block is installed with a spring, and the other side of the spring is connected to the rotating block.

[0012] Furthermore, a convex disk is movably connected to the top of the ferrule, a top protrusion of the convex disk is engaged with the fixing groove, and one end of the convex disk passes through the ferrule and is connected to the second transmission tooth.

[0013] Furthermore, a toothed sleeve is movably connected inside the ferrule, a limiting groove is symmetrically provided on the center of the toothed sleeve, a fixed sleeve is fixedly connected inside the ferrule and on one side of the toothed sleeve, a slide is symmetrically slidably connected on the fixed sleeve, one side of the slide is in contact with the limiting groove on the toothed sleeve, rollers are movably connected on both sides of the slide, and one side of the transmission tooth 2 is meshingly connected to the toothed sleeve.

[0014] Furthermore, a motor is fixed to the top of the movable frame by bolts, an output end of the motor passes through the movable frame and is fixed to the slot plate, and a distance measuring sensor is installed on the top of the movable frame and on one side of the motor.

[0015] Furthermore, one end of the two worms passes through the movable frame and is fixed with a transmission tooth 1, the two transmission teeth 1 are meshingly connected, one side of the movable frame is movably connected with a toothed disc, the toothed disc is meshingly connected with one of the transmission teeth 1, one side of the movable frame is movably connected with a belt pulley, and the belt pulley and the toothed disc are connected by a belt.

[0016] The present invention also provides a winding method of a cable and wire winding machine with adjustable tension, and the specific steps are as follows:

[0017] The left and right circulation paths are set according to the length of the material roller on the placement rack, the locking bolt on the top of the limit block is turned, the limit block inside the slide rail is moved to match the length of the material roller installed on the placement rack, and then the locking bolt is turned in the opposite direction so that the top block abuts against the inner wall of the slide rail and is locked;

[0018] The power mechanism on one side of the placement rack is started to drive the belt pulley to rotate. At the same time, the rotation of the toothed disk drives the transmission tooth connected to the worm to rotate. The rotation of the worm on one side drives the clamped block to move, and at the same time drives the entire sliding sleeve to move on the sliding rod. The limit column installed on the rotating block contacts the top side baffle of the limit block during the movement of the sliding sleeve, causing the rotating block to rotate in the opposite direction and pulling the entire clamp block to rotate in the opposite direction through the spring. The clamp block moves from the worm on one side to the worm on the other side that rotates in the opposite direction, so that the entire clamp block drives the sliding sleeve as a whole to move in the opposite direction on the sliding rod.

[0019] When it is necessary to adjust the tension of the cable and wire wound on the material roller, the position of the convex disk is identified by the distance measuring sensor on the inner wall of the top of the movable frame, and the motor is started through the controller. The rotation of the motor drives the convex disk to rotate, and the rotation of the convex disk drives the toothed sleeve to rotate through the second transmission tooth. The rotation of the toothed sleeve pushes the two slides on the fixed sleeve to move towards each other, and the rollers on both sides squeeze the cable and wire inward. The material roller that is wound again is squeezed by the rollers on the cable and wire, and the winding tension is improved.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, the locking bolt at the top of the limit block is adjusted to be placed on the slide rail by rotating itself, so as to match material rollers of different lengths for cable winding. When the material roller rotates, the worm gears on both sides are driven to rotate at the same time, and the limit column at the bottom of the rotating block is abutted against the baffle plate on the upper side of the limit block, so as to change the direction of the clamping block to clamp the worm gear, and the whole sliding sleeve is driven to move left and right on the sliding rod by the different rotation directions of the worm gear, and finally the cable is driven to be evenly wound on the material roller, so as to avoid that the material roller length is fixed, and the movable mechanism drives the cable to move left and right beyond the winding range of the material roller, and the cable winding on the material roller is messy, which is not conducive to the later use of the cable material roller.

[0022] In the present invention, the position of the ferrule on the groove disk is located by a distance measuring sensor. When the cable winding tension on the material roller needs to be adjusted, the groove disk is driven to rotate by a motor, and the convex point disk is coordinated to rotate to realize the rotation of the toothed sleeve inside the ferrule, thereby driving the slide on the fixed sleeve to move inside the ferrule, and the roller on the slide to move relatively, completing the squeezing and loosening of the outer wall of the cable, so that the subsequent material roller can adjust the winding tension of the cable by itself, with high flexibility.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-9 , the present invention provides a technical solution:

[0035] Embodiment 1: Cable and wire winding, mainly involves the left and right movement of the wire segment during winding and the adjustment of winding tightness, to avoid disordered distribution of cables and wires on the material roller and loose winding, such as Figure 1 As shown, the entire cable and wire winding body is a placing frame 1, which is used for installing the movable frame 2 and the material roller. Secondly, the installed movable frame 2 is mainly used for moving and clamping the cable and wire winding line segment;

[0036] The power for winding the entire cable wire comes from a belt pulley 6 that can rotate on one side of the placement rack 1. Figure 2 As shown, the belt pulley 6 rotates to drive the toothed disc 5 on one side of the movable frame 2 to rotate, and the rotation of the toothed disc 5 realizes the rotation of the two transmission teeth 1 4. At the same time, the worm 3 connected to the two transmission teeth 1 4 rotates in opposite directions, which is used to control the later sliding mechanism 13 to move left and right on the movable frame 2;

[0037] like Figure 2 As shown, a slide rail 8 is fixed to the inner wall at the bottom of the worm 3, and a limit block 9 is symmetrically slidably connected inside the slide rail 8. The main body of the limit block 9 is as shown in FIG. Figure 6 As shown, a side baffle 11 is fixed on the top, and secondly, a locking bolt 10 is symmetrically installed on the top of the entire limit block 9, and top blocks 12 are slidably connected on both sides of the limit block 9. The overall structure of the top block 12 is the same as that of the limit block 9, and the cross-section is in a trapezoid. At the same time, the entire top block 12 is embedded in the limit block 9. When the operator needs to adjust the winding range according to the length of the material roll, the locking bolt 10 at the top of the limit block 9 is rotated, and the upward movement of the locking bolt 10 causes the top block 12 to move, thereby adjusting the position of the limit block 9 as a whole in the slide rail 8. After the position is adjusted, the locking bolt 10 is rotated in the opposite direction, and the locking bolt 10 moves down to abut against the inclined surface of the top block 12, causing the top block 12 to move outward and abut against the inner wall of the slide rail 8, completing the fixing of the position of the entire limit block 9 in the slide rail 8;

[0038] A slide bar 7 is symmetrically fixed on the top of the slide rail 8, and a slide mechanism 13 is slidably connected to the slide bar 7, wherein the main body of the slide mechanism 13 is a slide sleeve 131, and a clamping sleeve 133 is fixed on the top of the slide sleeve 131. When winding cables and wires, the cables and wires need to be passed through the clamping sleeve 133 and fixed on the material roller. Secondly, a clamping block 136 and a rotating block 134 are rotatably connected to one side of the slide sleeve 131, wherein the rotating block 134 faces downward, and the clamping block 136 faces upward. The rotating block 134 and the clamping block 136 are connected by a spring 137, as shown in FIG. Figure 5 As shown, due to the pulling of the spring 137, one side of the rotating block 134 abuts against the limiting bolt 132 on the side of the sliding sleeve 131, and the clamping block 136 is clamped with the texture on one side of the worm 3, so that the clamping block 136 moves to one side after the worm 3 rotates;

[0039] The engagement of the block 136 with the worm gear 3 drives the sliding sleeve 131 to move as a whole on the sliding rod 7. For this reason, whenever the limit column 135 at the bottom of the entire rotating block 134 contacts the side baffle 11 on the slide rail 8, the rotating block 134 guided by the side baffle 11 begins to move sideways and rotate. When the rotating block 134 rotates to the other side, the spring 137 is used to simultaneously drive the block 136 to rotate, so that the block 136 moves from one side of a single worm gear 3 to the surface of the other worm gear 3. Since the two worm gears 3 rotate in opposite directions, when the block 136 changes direction, the activity direction of the entire sliding sleeve 131 changes at the same time, so that the entire sliding sleeve 131 can be moved left and right on the sliding rod 7. At the same time, the movable limit block 9 is used to adjust the spacing between the side baffles 11 on both sides, so as to realize the winding of cables and wires on material rollers of different lengths, thereby avoiding the problem of uneven distribution of cables on the material rollers caused by the mismatch between the left and right activity ranges and the length of the material rollers.

[0040] Embodiment 2: Considering the adjustment of the tightness between the cable and the material roller, a convex plate 14 is installed on the entire ferrule 133, such as Figure 4 As shown, a movable slide 17 is installed in the clamping sleeve 133, and a roller 18 is movably connected to the slide 17, wherein the roller 18 is used to clamp the outer wall of the cable to prevent the cable from being wound too loosely, and a rubber film is provided on the outer wall of the roller 18 to protect the cable and play a certain role in extrusion buffering;

[0041] For adjusting the spacing between the rollers 18 on the two carriages 17 in the entire sleeve 133, as shown in FIG. Figure 8 and Fig. 9 As shown, a toothed sleeve 15 is movably connected inside the entire ferrule 133, and a limiting groove 19 is symmetrically provided on the toothed sleeve 15, and the limiting groove 19 is arc-shaped. At the same time, the convex disk 14 passes through one side of the ferrule 133 and is fixed with a transmission tooth 20, and the transmission tooth 20 is meshed and connected with the tooth pattern of the side wall of the toothed sleeve 15, so that the entire transmission tooth 20 rotates, which will drive the toothed sleeve 15 to rotate;

[0042] A fixed sleeve 16 is located inside the entire ferrule 133 and fixedly connected to one side of the toothed sleeve 15, wherein a slide 17 is symmetrically slidably connected to the fixed sleeve 16, and a protrusion on one side of the slide 17 abuts against an upper limit groove 19 on the toothed sleeve 15, so that after the toothed sleeve 15 rotates, the limit groove 19 is used to constrain one side of the slide 17, so that the slide 17 as a whole moves on the fixed sleeve 16, and the moving direction is related to the rotation direction of the toothed sleeve 15. The toothed sleeve 15 rotates clockwise, causing the two slides 17 on the fixed sleeve 16 to move toward each other, and the distance between the two rollers 18 is reduced, which is used to clamp both sides of the cable;

[0043] However, considering that the carriage 17 is affected by gravity between the fixed sleeves 16, it is ensured that when the clamping sleeve 133 drives the cable to move left and right, the pressure applied by the roller 18 remains unchanged. Figure 7 As shown, a fixed groove 21 is installed on the top inner wall of the entire movable frame 2, and the groove of the fixed groove 21 is used to limit the top two sides of the convex wheel to prevent the convex wheel from rotating. However, considering that the spacing of the entire slide 17 needs to be adjusted, a motor 23 is also installed on the top of the entire movable frame 2. The output end of the motor 23 passes through the movable frame 2 and is fixed with a groove plate 22. The circular groove plate 22 is also provided with a groove. The groove on the groove plate 22 is flush with the groove on the fixed groove 21. Whenever the sliding sleeve 131 drives the convex plate 14 to coincide with the vertical center point of the groove plate 22, the motor 23 drives the groove plate 22 to rotate. The rotation of the groove plate 22 will drive the convex plate 14 to rotate, causing the spacing between the two slides 17 installed in the clamping sleeve 133 to change.

[0044] However, considering that the entire convex disk 14 will continue to move, the entire groove disk 22 rotates in units of 180° to ensure that the grooves on the entire groove disk 22 and the grooves on the fixed grooves 21 are unobstructed, thereby avoiding obstruction in the movement of the convex disk 14. At the same time, due to the fixed angle rotation of the groove disk 22, the moving distance of the slide 17 in the ferrule 133 is fixed each time. For this purpose, the entire transmission tooth 20 can be reduced to expand the spacing adjustment of the entire slide 17;

[0045] At the same time, ensure that the vertical center points of the entire convex disk 14 and the groove disk 22 coincide with each other, and prevent the rotation of the groove disk 22 from causing deformation of the connecting sleeve 133 at the top of the sliding sleeve 131. A distance sensor 24 is installed on the top of the entire movable frame 2. First, determine the vertical coincidence position of the center of the convex disk 14 and the center of the groove disk 22, and use the distance sensor 24 to measure the distance between the two points on the sleeve 133. Only when the measured distances of these two points match, can it be determined that the center of the entire convex disk 14 and the center of the groove disk 22 coincide with each other vertically, and then the tension adjustment signal will be sent to the motor 23 to control the motor 23 to rotate in a specific direction. The rotation of the groove disk 22 drives the convex disk 14 to rotate, adjust the distance between the slides 17 on both sides of the sleeve 133, and complete the clamping of the cables on both sides of the rollers 18, so that when the material roller is tightening the cable, the higher the cable tension, the higher the cable winding tension on the material roller.

[0046] The working process and principle of the present invention are as follows:

[0047] The left and right circulation paths are set according to the length of the loading roller of the placement rack 1, the locking bolt 10 at the top of the limit block 9 is rotated, the limit block 9 in the slide rail 8 is moved to match the length of the material roller installed on the placement rack 1, and then the locking bolt 10 is rotated in the opposite direction so that the top block 12 abuts against the inner wall of the slide rail 8 and is locked;

[0048] The power mechanism on one side of the placement rack 1 is started to drive the belt pulley 6 to rotate. At the same time, the rotation of the toothed disc 5 drives the transmission tooth 14 connected to the worm 3 to rotate. The rotation of the unilateral worm 3 drives the clamping block 136 to move, and at the same time drives the entire sliding sleeve 131 to move on the sliding rod 7. When the limiting column 135 installed on the rotating block 134 contacts the top side baffle 11 of the limiting block 9 during the movement of the sliding sleeve 131, the rotating block 134 is caused to rotate in the opposite direction and the entire clamping block 136 is pulled to rotate in the opposite direction through the spring 137. The clamping block 136 moves from the worm 3 on one side to the worm 3 rotating in the opposite direction on the other side, so that the entire clamping block 136 drives the sliding sleeve 131 to move in the opposite direction on the sliding rod 7 as a whole.

[0049] When it is necessary to adjust the tension of the cable and wire wound on the material roller, the position of the convex disk 14 is identified by the distance measuring sensor 24 on the inner wall at the top of the movable frame 2, and the motor 23 is started by the controller. The rotation of the motor 23 drives the convex disk 14 to rotate. The rotation of the convex disk 14 drives the toothed sleeve 15 to rotate through the transmission gear 20. The rotation of the toothed sleeve 15 pushes the two slides 17 on the fixed sleeve 16 to move toward each other. The rollers 18 on both sides squeeze the cable and wire inward. The material roller that is wound again is squeezed by the rollers 18 on the cable and wire, and the winding tension is improved.
