Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to a horizontal untwisting machine. Background Technology

[0002] In traditional cable manufacturing, torsional stress is generated inside the cable after processes such as stranding or laying. If this torsional stress is not addressed, it can lead to problems such as twisting and deformation during subsequent use, affecting the cable's appearance quality and actual performance. For example, it may cause knots or tangles during wiring, reducing construction efficiency and even potentially causing electrical faults, affecting the stability and safety of power transmission.

[0003] Currently, cable manufacturers use untwisting machines to address the torsional stress problem in cables. During cable laying, the cable is rotated in the opposite direction, creating a reverse pre-twist; this process is called untwisting. Most untwisting machines on the market have complex structures and require a large footprint, increasing factory space and production costs. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a horizontal untwisting machine with a more compact structure, smaller footprint, and easier operation.

[0005] Therefore, the technical solution of this utility model is: a horizontal untwisting machine, including a base frame, support frames on both sides of the base frame, and a rectangular rocker frame mounted on the top of the support frames; the front and rear ends of the rectangular rocker frame are rotatably mounted on the top of the support frames through bearings, and one end of the rectangular rocker frame is connected to a drive motor through a pulley set; an I-beam wire wheel is rotatably mounted inside the rectangular rocker frame, and a wire feeding motor that drives the I-beam wire wheel to rotate is mounted on the side of the rectangular rocker frame;

[0006] The base frame contains a lifting mechanism located directly below the rectangular cradle. The lifting mechanism includes a lifting frame, a lifting plate, and a lifting cylinder. The lifting frame includes two lifting arms on both sides, each lifting arm including a first lifting rod and a second lifting rod that are parallel to each other. One end of the first lifting rod and the second lifting rod are rotatably mounted on a support frame on one side, and the other end is rotatably mounted on the lifting plate. The bottom of the lifting cylinder is rotatably mounted on the base frame, and a connecting rod is installed on the cylinder rod of the lifting cylinder. Both ends of the connecting rod are rotatably connected to the first lifting rods on both sides. The lifting cylinder drives the lifting plate to rise and fall through the lifting arms.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the lifting plate has a circular groove in the middle, a rotating disk is provided in the circular groove, and an auxiliary wheel is provided on the rotating disk.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the side of the base frame is provided with an inclined feeding ramp, the highest point of which is flush with the lifting plate at the lowest position.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the lifting mechanism further includes a first lifting mounting seat, which is fixed on the support frame; the lifting plate is provided with a second lifting mounting seat on the side facing the lifting frame; the ends of the first lifting rod and the second lifting rod are respectively rotatably mounted on the first lifting mounting seat and the second lifting mounting seat via pins; the first lifting mounting seat, the second lifting mounting seat, the first lifting rod and the second lifting rod have a parallelogram structure.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the lifting cylinder drives the first lifting rods on both sides to lift upwards through the connecting rod, and the first lifting rods and the second lifting rods drive the lifting plate to move upwards.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the front and rear sides of the rectangular cradle are provided with a first guide roller group and a second guide roller group, and the first guide roller group and the second guide roller group are distributed in a grid pattern; the front and rear sides of the rectangular cradle are each provided with a hollow rotating part in the middle, and the middle of the rotating part is a wire hole.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: the rotating part of the rectangular cradle is mounted on the support frame through bearings, and a first pulley is mounted on the outer side of one of the rotating parts; a second pulley is mounted on the output shaft of the drive motor and is connected to the first pulley through a belt.

[0013] Based on the above scheme and as a preferred embodiment of the above scheme: the rectangular cradle is provided with a fixed top head and a movable top head on the left and right sides respectively, which are clamped at the center holes on both sides of the I-beam reel; the fixed top head is connected to the output shaft of the wire feeding motor through a gear set, which drives the I-beam reel to rotate.

[0014] The usage steps are as follows:

[0015] In the initial stage, the lifting plate is at its lowest position. The I-beam roller is rolled into the lifting plate from the feeding ramp. At this time, the axis of the I-beam roller is parallel to the long side (front and rear sides) of the rectangular cradle.

[0016] Rotate the I-beam roller 90 degrees. A rotating disc is located in the middle of the lifting plate, making it easier to rotate the I-beam roller.

[0017] When the lifting cylinder is activated, the cylinder rod extends, driving the first lifting rod and the second lifting rod to rotate upward. Since the first lifting mounting seat is fixed on the support frame, the mounting points of the first lifting rod, the second lifting rod and the first lifting mounting seat are on the same vertical line. Therefore, the mounting points of the first lifting rod, the second lifting rod and the lifting plate are also vertically distributed, keeping the lifting plate in a horizontal state and raising the I-beam roller into the rectangular cradle.

[0018] The movable mandrel is used to push the I-beam roller onto the fixed mandrel, so that the movable mandrel and the fixed mandrel cooperate to clamp the two ends of the I-beam roller.

[0019] After the I-beam roller is fixed in place, the lifting cylinder retracts, driving the lifting plate to move down to the initial position.

[0020] Pull the cable end out of the I-beam reel, pass it through the first guide roller group and the second guide roller group on one side, and then out through the wire hole in the middle of the rotating part;

[0021] Start the wire feeding motor, which drives the H-beam wire reel to rotate and feed the wire;

[0022] At the same time, the drive motor is started, and the output shaft of the drive motor drives the second pulley, which in turn drives the first pulley via the belt, ultimately causing the rectangular cradle to rotate. While the rectangular cradle is rotating, the cable is unloaded. During this process, the cable is rotated in the opposite direction to form a reverse pre-torsion. The un-torsion rate can be obtained by adjusting the ratio of the unloading speed to the number of rotations for un-torsion.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] A lifting mechanism is installed directly below the rectangular cradle, making the overall layout of the equipment more compact and effectively reducing the floor space. An inclined feeding ramp is set on the side of the base frame, which allows the I-beam wire pulley to roll directly from the feeding ramp into the lifting plate, simplifying the feeding process. At the same time, a rotating disk is set in the middle of the lifting plate to rotate the angle of the I-beam wire pulley, making it easier for the I-beam wire pulley to be installed onto the rectangular cradle later.

[0025] The lifting mechanism, with its parallelogram structure, is used to lift the I-beam rollers. During lifting, the lifting plate remains horizontal, ensuring the stability of the I-beam rollers and preventing them from shifting or falling due to tilting of the lifting plate. This ensures the safety and stability of the equipment operation. Attached Figure Description

They should not be construed as limiting the specific protection scope of this utility model.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0034] See the attached drawings. The horizontal unwinding machine described in this embodiment includes a base frame 1, with support frames 2 on both sides of the base frame, and a rectangular rocker arm 3 mounted on the top of the support frames 2. A hollow rotating part 31 is provided at the middle of each of the front and rear ends of the rectangular rocker arm 3. The rotating part 31 is rotatably mounted on the top of the support frame 3 via bearings 4, and one end of each part is connected to a drive motor 51 via a pulley set. A first pulley 52 is mounted on the outer side of the rotating part 31 on one side of the rectangular rocker arm 3. A second pulley 53 is mounted on the output shaft of the drive motor 51 and is connected to the first pulley 52 via a belt 54.

[0035] A wire reel 6 is rotatably mounted inside the rectangular cradle 3, and a wire feeding motor 71 is mounted on the side of the rectangular cradle 3 to drive the wire reel 6 to rotate. A fixed top 72 and a movable top 73 are respectively rotatably mounted on the left and right sides of the rectangular cradle 3, and both are clamped at the center holes on both sides of the wire reel 6. The fixed top 72 is connected to the output shaft of the wire feeding motor 71 through a gear set 74, which can drive the wire reel 6 to rotate. A rotating handle 75 is provided on one side of the movable top 73, which can drive the movable top 73 to move towards the fixed top 72, thereby fixing the wire reel 6.

[0036] The rectangular rocker arm 3 has a first guide roller group 81 and a second guide roller group 82 inside both the front and rear sides. The first guide roller group 81 and the second guide roller group 82 are arranged in a grid pattern, so that the cable can pass through the middle of the grid, which can guide the cable and prevent the cable from being worn. The rotating part 31 on the front and rear sides of the rectangular rocker arm 3 has a wire hole 32 in the middle, and the cable can pass through the wire hole 32 on either side as needed.

[0037] The base frame 1 is equipped with a lifting mechanism 9, located directly below the rectangular cradle 3, making the overall structure more compact. The lifting mechanism 9 includes a lifting frame 91, a lifting plate 92, and a lifting cylinder 93. The lifting frame 91 includes two lifting arms on both sides, each lifting arm including a first lifting rod 911, a second lifting rod 912, a first lifting mounting seat 913, and a second lifting mounting seat 914 distributed in a parallelogram. The first lifting mounting seat 913 is fixed to the support frame 2, and the second lifting mounting seat 914 is installed on the side of the lifting plate 92 facing the lifting frame 91. The first lifting rod 911 and the second lifting rod 912... The two ends are respectively rotatably mounted on the first lifting mounting base 913 and the second lifting mounting base 914 via pins; the bottom of the lifting cylinder 93 is rotatably mounted on the base frame 1, and a connecting rod 94 is mounted on the cylinder rod of the lifting cylinder 93. The two ends of the connecting rod 94 are rotatably connected to the first lifting rods 911 on both sides; the lifting cylinder 93 drives the first lifting rods 911 on both sides to lift upward through the connecting rod 94, thereby causing the entire parallelogram structure lifting arm to rotate upward. During the rotation, the parallelogram structure is always maintained (i.e., the short side is always vertical), driving the lifting plate to move upward, and maintaining a horizontal position during the upward movement.

[0038] The lifting plate 92 has a circular groove in the middle, and a rotating disk 921 is provided in the circular groove. The rotating disk 921 is equipped with an auxiliary wheel 922. After the I-beam wire wheel 6 is placed on the lifting plate 92, it can be rotated to allow it to be installed in the rectangular cradle 3. The base frame 1 has an inclined feeding ramp 10 on its side. The highest point of the feeding ramp 10 is flush with the lifting plate 92 at its lowest position, which facilitates pushing the I-beam wire wheel 6 onto the lifting plate 92.

[0039] The usage steps are as follows:

[0040] In the initial stage, the lifting plate 92 is at its lowest position, and the I-beam roller 6 is rolled into the lifting plate 92 from the feeding slope 10. At this time, the axis of the I-beam roller 6 is parallel to the long side (front and rear sides) of the rectangular cradle 3.

[0041] Rotate the I-beam roller 6 by 90 degrees. The lifting plate 92 has a rotating disk 921 in the middle, which makes it easier to rotate the I-beam roller 6.

[0042] When the lifting cylinder 93 is activated, the cylinder rod of the lifting cylinder 93 extends, driving the lifting arm to rotate upward. Since the first lifting mounting seat 913 is fixed on the support frame 2, the mounting points of the first lifting rod 911, the second lifting rod 912 and the first lifting mounting seat 913 are on the same vertical line. Therefore, the mounting points of the first lifting rod 911, the second lifting rod 912 and the second lifting mounting seat 914 (fixed to the lifting plate 92) are also vertically distributed, so that the lifting plate 92 rises while maintaining a horizontal state, raising the I-beam roller 6 into the rectangular cradle 3.

[0043] The movable mandrel 73 is used to push the I-beam roller 6 onto the fixed mandrel 72, so that the movable mandrel 73 and the fixed mandrel 72 cooperate to clamp the two ends of the I-beam roller 6.

[0044] After the H-beam roller 6 is fixed, the lifting cylinder 93 retracts, driving the lifting plate 92 to move down to the initial position;

[0045] Pull the cable end out of the I-beam reel 6, pass it through the first guide roller group 81 and the second guide roller group 82 on one side, and then out through the wire hole 32 in the middle of the rotating part 31.

[0046] Start the wire feeding motor 71, which drives the H-beam wire reel 6 to rotate and feed the wire.

[0047] At the same time, the drive motor 51 is started, and the output shaft of the drive motor drives the second pulley 53, which drives the first pulley 52 through the belt 54, and finally drives the rectangular cradle 3 to rotate. While the rectangular cradle 3 is rotating, the cable is released. During this process, the cable is rotated in the opposite direction to form a reverse pre-twist. The desired pre-twist rate can be obtained by adjusting the ratio of the cable release speed to the number of rotations for unwinding.

[0048] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
