Description

Technical Field

[0001] This utility model relates to the field of wire and cable processing technology, and in particular to a novel wire stretching and winding device. Background Technology

[0002] As the final step in wire and cable processing, winding is used to collect the processed wires for storage and transportation. Therefore, the efficiency and neatness of wire winding are very important.

[0003] In existing technology, if the wire is not sufficiently stretched before winding, the residual stress on the wire's surface and inside will cause the wire wound onto the spool to curl and deform, preventing it from being tightly bonded to the spool. This results in an uneven spool, large gaps between the wires, and affects the quality and efficiency of wire winding.

[0004] To address this issue, we propose a novel wire stretching and winding device. Utility Model Content

[0005] The purpose of this invention is to provide a novel wire stretching and winding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel wire stretching and winding device includes a frame and a wire frame. Wire wheels are rotatably mounted at both ends of the wire frame, which also has a cutting mechanism. A winding mechanism is provided on the frame, and several cross-shaped stretching mechanisms are also provided on the wire frame. Each cross-shaped stretching mechanism consists of a set of horizontal straightening wheels and a set of vertical straightening wheels, with their clamping center lines coinciding. The rollers of both the horizontal and vertical straightening wheels are supported by C-shaped frames. Each C-shaped frame is slidably connected to an adjustment box. A double-ended screw is provided inside the adjustment box, with symmetrical movable blocks screwed onto its outer wall. These movable blocks are connected to the C-shaped frames one-to-one. An adjustment motor for driving the double-ended screw to rotate is installed at the outer end of the adjustment box.

[0008] In a further embodiment, a bracket is fixed to the rear side of the conductor frame, a movable sleeve is fixed in the middle of the bracket, and a reciprocating screw passes through the movable sleeve. One end of the reciprocating screw is connected to a reciprocating motor, and the reciprocating screw is mounted on the frame through a bearing seat. A pair of sliding rods are also fixed to the rear side of the bracket, and a bushing is correspondingly installed on the frame. The sliding rods slide through the inside of the bushing.

[0009] In a further embodiment, the cutting mechanism includes an upper blade and a lower blade, and a first cylinder is connected to the upper blade. The first cylinder controls the upper blade to move closer to or away from the lower blade to cut the wire.

[0010] In a further embodiment, the winding mechanism includes a winding reel and a limiting reel, and a second cylinder is connected to the front side of the limiting reel. The second cylinder controls the limiting reel to move closer to or away from the winding reel to clamp or release the wound reel.

[0011] In a further embodiment, anti-slip sleeves are provided on the outer circumferential sidewalls of both the horizontal and vertical straightening rollers.

[0012] In a further embodiment, the roller shafts of the horizontal and vertical straightening rollers are rotatably connected to the C-frame via bearings, and pressure sensors are mounted on the outside of the roller shafts.

[0013] In a further embodiment, sliders are symmetrically installed on both sides of the movable block, and straight rails are symmetrically installed in the slots of the adjustment box panel. The sliders are slidably connected to the straight rails, and the sliding direction is consistent with the axial direction of the double-ended screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a cross-shaped stretching mechanism to simultaneously straighten and stretch the wire in both horizontal and vertical directions, effectively eliminating multidimensional bending of the wire, improving straightening accuracy and wire quality, and ensuring that the wound wire is tightly bonded to the spool with minimal gaps between the wires, thus guaranteeing the neatness of the spool. Furthermore, the double-headed screw and movable block design within the adjustment box, in conjunction with the adjustment motor, enables rapid and synchronous adjustment of the straightening wheel, accommodating wires of different diameters and simplifying operation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5A novel wire stretching and winding device includes a frame 1 and a wire frame 2. Wire wheels 3 are rotatably mounted at both ends of the wire frame 2 to guide the movement of the wire. A cutting mechanism 4 is also installed on the wire frame 2, including an upper blade 41 and a lower blade 42. The lower blade 42 is fixed to the base plate of the wire frame 2. The upper blade 41 is connected to the output shaft of a first cylinder 43. The cylinder body of the first cylinder 43 is fixed to the back plate of the wire frame 2. The upper blade 41 is controlled to move closer to or further away from the lower blade 42 by the cylinder to cut the wire.

[0026] The conductor frame 2 is equipped with several cross-shaped tensioning mechanisms 6. Each mechanism consists of a set of horizontal straightening wheels 61 and a set of vertical straightening wheels 62. Their clamping center lines coincide to ensure that the wire is straightened simultaneously in both the horizontal and vertical directions. The rollers of the horizontal straightening wheels 61 and the vertical straightening wheels 62 are supported by C-shaped frames 63. Each set of C-shaped frames 63 is slidably connected to the adjusting box 64. The adjusting box 64 is equipped with a double-ended screw 642. The outer wall of the double-ended screw 642 is symmetrically screwed with movable blocks 641. The movable block 641 is connected to the C-shaped frame 63 in a one-to-one correspondence. The adjustment motor 643 is installed on the outer end of the adjustment box 64, which drives the double-headed screw 642 to rotate, thereby driving the two movable blocks 641 to control the two C-shaped frames 63 to move towards or away from each other, realizing the adjustment of the spacing of the straightening wheels, while ensuring that the clamping center does not shift. Slider blocks 644 are symmetrically installed on both sides of the movable block 641. Straight rails 645 are symmetrically installed in the slots of the panel of the adjustment box 64. The sliders 644 and the straight rails 645 are slidably connected to ensure smooth movement.

[0027] The horizontal straightening roller 61 and the vertical straightening roller 62 are provided with anti-slip sleeves 7 on their outer circumferential sidewalls. The anti-slip sleeves 7 are made of wear-resistant rubber to increase friction and prevent slippage. The roller shaft is rotatably connected to the C-shaped frame 63 through bearings and is equipped with a pressure sensor 646. The pressure sensor 646 is preferably a piezoelectric or strain gauge sensor. Its signal output terminal is connected to the control system of an electrical connection device. The control system is a programmable logic controller (PLC) or an industrial microcontroller. The adjusting motor 643 is also electrically connected to the control system, so that when the monitoring roller applies a certain pressure to the wire clamping blade, it can feed back to the control system and control the adjusting motor 643 to stop working, thereby realizing automatic clamping adjustment.

[0028] A bracket 21 is fixed to the rear side of the conductor frame 2. A movable sleeve 22 is fixed in the middle of the bracket 21. A reciprocating screw 23 passes through the movable sleeve 22. Both ends of the reciprocating screw 23 are mounted on the frame 1 through bearing seats. One end passes through the bearing seat and connects to the reciprocating motor 24. The reciprocating motor 24 is fixed on the bearing seat. A pair of sliding rods 26 are also fixed to the rear side of the bracket 21. The sliding rods 26 are parallel to the reciprocating screw 23. A bushing 25 is installed on the frame 1. The sliding rods 26 slide through the inside of the bushing 25, so that the conductor frame 2 can move smoothly along the reciprocating screw 23.

[0029] The winding mechanism 5 includes a winding reel 51 and a limiting plate 52. The winding reel 51 is rotatably mounted on the frame 1, and the frame 1 is equipped with a geared motor (not shown in the figure) that drives the winding reel 51 to rotate. The limiting plate 52 is aligned with the axis of the winding reel 51. A second cylinder 53 is connected to the front side of the limiting plate 52. The cylinder controls the limiting plate 52 to move closer to or further away from the winding reel 51 to clamp or release the wound reel.

[0030] Work process: The wire first passes through the wire wheel 3 on the wire frame 2 to enter the device, then through the cross-shaped stretching mechanism 6, then through the blades, then through another wire wheel 3, and finally the wire end is stuck on the winding disc 51. The limiting disc 52 presses against the winding disc 51 under the action of the second cylinder 53.

[0031] The start-up adjustment motor 643 drives the double-headed screw 642 to rotate, adjusting the spacing of the straightening wheels to adapt to the wire diameter. The pressure sensor 646 monitors the tension in real time. The horizontal straightening wheel 61 and the vertical straightening wheel 62 work simultaneously to eliminate multidimensional bending.

[0032] Then, the winding reel 51 is started to rotate and wind the wire, pulling the wire through the cross-shaped stretching mechanism 6. At the same time, the reciprocating motor 24 drives the reciprocating screw 23 to rotate, causing the wire frame 2 to move back and forth, so that the wire is evenly wound on the winding mechanism 5. When it is necessary to cut the wire, the first cylinder 43 pushes the upper blade 41 close to the lower blade 42 to complete the cutting.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
