Description

Technical Field

[0001] The invention relates to the technical field of cable production, in particular to a wire stranding machine with a ship frame type cradle structure. Background Art

[0002] A wire stranding machine is a device specially used to twist and strand multiple metal wires (such as copper wire, aluminum wire or steel wire) or optical fibers. Its main function is to twist a single material into a twisted structure through a certain process, thereby enhancing the mechanical strength, flexibility and conductivity of the product while reducing interference.

[0003] For example, an automatic high-speed wire stranding machine disclosed in a Chinese patent with patent publication number CN104376931B includes a high-speed servo motor, a spool, a variable take-up wheel, a fixed take-up wheel, a magnetic powder clutch, a wire arrangement mechanism, a spool seat, and left and right threading shafts symmetrically arranged on both sides of the spool seat. The wire arrangement mechanism includes a wire arranger, a wire arrangement shaft, a mounting rod, a first horizontal guide wheel, a second horizontal guide wheel, a third horizontal guide wheel, and a vertical guide wheel. The wire arrangement shaft is arranged between a left disc and a right disc, and the wire arranger is arranged on the wire arrangement shaft. One end of the mounting rod is connected to the left disc, and the other end is connected to the right disc. The first horizontal guide wheel and the second horizontal guide wheel are correspondingly arranged at both ends of the mounting rod. The third horizontal guide wheel is arranged on the wire arranger and is on the same horizontal plane as the first horizontal guide wheel and the second horizontal guide wheel. The vertical guide wheel is arranged on the wire arranger at a position corresponding to one side of the third horizontal guide wheel.

[0004] In the above-mentioned prior art, since the multiple guide wheels are distributed along the short axis diameter of the twisting bow, and the bobbin and the wire arranger are also distributed along the short axis diameter of the twisting bow, the short axis diameter of the twisting bow will be larger, and finally the rotation radius of the twisting machine will be larger. Since the magnitude of the centrifugal force is proportional to the rotation radius, the centrifugal force of the twisting machine in the above-mentioned prior art is larger during the twisting process. The increase of the centrifugal force is more likely to cause the imbalance of the machine body, resulting in increased vibration, thereby increasing the noise. Summary of the invention

[0029] The following will be combined Figure 1-Figure 6 The present invention is further illustrated by the following embodiments.

[0030] Embodiment 1

[0031] This embodiment discloses a wire stranding machine with a ship frame type cradle structure.

[0032] Reference Figures 1 to 3The stranding machine of the ship frame cradle structure includes a chassis 1, and a left fixed bearing seat 21 and a right fixed bearing seat 22 are arranged between the left and right inner sides of the chassis 1, and the axes of the left fixed bearing seat 21 and the right fixed bearing seat 22 are collinear. A left common rotating shaft 23 is rotatably arranged in the left fixed bearing seat 21, and a right threading rotating shaft 24 is rotatably arranged in the right fixed bearing seat 22, and the axes of the left common rotating shaft 23 and the right threading rotating shaft 24 are collinear, and the right threading rotating shaft 24 is provided with a threading hole along the axial direction. The chassis 1 is provided with a main driving motor 25, and the output shaft of the main driving motor 25 is connected to the right threading rotating shaft 24 to drive the right threading rotating shaft 24 to rotate. A coupling mechanism is connected between the left common rotating shaft 23 and the right threading rotating shaft 24, so that the main driving motor 25 synchronously drives the left common rotating shaft 23 and the right common rotating shaft to rotate. The inner ends of the left common rotating shaft 23 and the right threading rotating shaft 24 are both fixedly connected with a bow seat 26, and the two bow seats 26 rotate with the rotation of the left common rotating shaft 23 and the right threading rotating shaft 24. Two twisting bows 27 are symmetrically connected between the two bow seats 26, and the two twisting bows 27 rotate with the rotation of the two bow seats 26. The inner sides of the two twisting bows 27 are arranged with multiple guide blocks arranged at intervals. When twisting wires, multiple wires pass through the right threading rotating shaft 24 and multiple guide blocks of one of the twisting bows 27 in turn, and twist wires are twisted with the rotation of the twisting bow 27. The right threading rotating shaft 24 is provided with a right guide wheel 28 at the inner end of the wire hole, and the multiple wires passed through the right threading rotating shaft 24 are guided to one of the twisting bows 27 through the right guide wheel 28. The left fixed bearing seat 21, the right fixed bearing seat 22, the left common rotating shaft 23, the right threading rotating shaft 24, the main driving motor 25, the coupling mechanism, the bow seat 26 and the twisting bow 27 constitute the rotation control mechanism of the twisting machine of the present invention.

[0033] Reference Figure 3 and Figure 4 A take-up frame 3 is rotatably connected between the left common rotating shaft 23 and the right threading rotating shaft 24. The take-up frame 3 remains stationary when the rotation control mechanism rotates, that is, it does not rotate with the rotation of the rotation control mechanism. A bobbin (not shown in the figure) is rotatably arranged on the take-up frame 3. The bobbin is arranged horizontally and its axis is perpendicular to the rotation axis of the rotation control mechanism. The bobbin is connected to a winding drive motor, which is used to control the bobbin to rotate and take up the wire. The wire take-up frame 3 is provided with a wire arrangement mechanism, and the twisted wire is stored on the bobbin after passing through the wire arrangement mechanism. The wire arrangement mechanism includes a first guide wheel 31, a second guide wheel 32, a third guide wheel 33, a fourth guide wheel 34 and a wire arranger 42 arranged on the left side of the wire take-up frame 3, wherein the fourth guide wheel 34 is arranged on the wire arranger 42, and the four guide wheels of the wire take-up frame 3 are distributed along the long axis diameter of the twisting bow 27, and the wire take-up frame 3 and the bobbin are distributed along the long axis diameter of the twisting bow 27. Through the above distribution, the short axis diameter of the twisting bow 27 can be effectively shortened, thereby shortening the rotation radius of the twisting machine, avoiding excessive centrifugal force, and ultimately reducing the vibration of the machine body and reducing noise.

[0034] Reference Figure 3 and Figure 4 Specifically, in the present embodiment, the first guide wheel 31 is arranged in front of the rotation axis of the rotation control mechanism, the second guide wheel 32 is arranged above the rotation axis of the rotation control mechanism, the second guide wheel 32 is located on the left side of the first guide wheel 31, the third guide wheel 33 is arranged above the rotation axis of the rotation control mechanism, and its height is higher than the second guide wheel 32, the third guide wheel 33 is located on the right side of the second guide wheel 32, the cable arranger 42 is arranged above the rotation axis of the rotation control mechanism, the cable arranger 42 is located on the right side of the third guide wheel 33 and between the third guide wheel 33 and the spool, and the fourth guide wheel 34 is arranged on the right side of the cable arranger 42. Furthermore, the axis of the fourth guide wheel 34 is parallel to the axis of the spool, and the axes of the first guide wheel 31, the second guide wheel 32, the third guide wheel 33 and the fourth guide wheel 34 intersect each other on the vertical projection plane. When the directions of the four guide wheels on the take-up frame 3 are different, the wire can pass through each guide wheel at a different angle, avoiding continuous friction between the wire and the guide wheel in the same direction, reducing local wear, improving the quality of the wire, and avoiding excessive load on the guide wheel, thereby extending the service life of the guide wheel. In addition, the different angles of the multiple guide wheels can help to more evenly distribute the tension applied to the cable, avoiding wire breakage, knotting or other problems caused by uneven tension.

[0035] Reference Figure 4 In order to realize the wire arranging function of the wire arranging device 42, a mounting seat 4 and a wire arranging control mechanism arranged on the mounting seat 4 are provided on the wire take-up frame 3. In this embodiment, the wire arranging control mechanism is a first screw mechanism 41, and the wire arranging device 42 is movably arranged on the first screw mechanism 41 along the front-back direction.

[0036] Reference Figure 1 A lead structure is provided on the right side of the stranding machine, and the lead structure includes a guide rod 51, four movable blocks 52, and four retracting frames 53. The guide rod 51 is fixedly provided on the right side of the chassis 1, and the length direction of the guide rod 51 is parallel to the rotation axis of the rotation control mechanism. The four movable blocks 52 are sleeved on the guide rod 51, and the four retracting frames 53 are respectively fixed on the four movable blocks 52. When multiple wires pass through the four retracting frames 53 from the outside to the inside, they are gradually retracted and finally enter the shaft hole of the right threading shaft 24. In addition, the four movable blocks 52 are all tightened on the guide rod 51 by threaded push rods, and the spacing of the four movable blocks 52 can be adjusted according to needs.

[0037] Reference Figure 4A traction wheel group is also provided on the left side of the take-up frame 3. The traction wheel group is provided between the third guide wheel 33 and the fourth guide wheel 34. The traction wheel group includes an upper traction wheel 61 and a lower traction wheel 62. The lower traction wheel 62 is driven. After the wires are twisted, they are wound several times in the traction wheel group and then led to the first guide wheel 31. The traction wheel group can provide traction for the wires, so that the wires can pass through the four guide wheels of the take-up frame 3 in sequence. In addition, two small guide wheels with parallel axes are provided on the wire arrangement device 42, in order to distribute the tension of the wires more evenly.

[0038] Reference Figure 2 , a lifting tray 71 is also provided in the chassis 1, and the lifting tray 71 is located below the take-up frame 3. The lifting tray 71 is used to receive the bobbin, so that the staff can put in or take out the bobbin. Specifically, a second screw mechanism 72 is provided in the chassis 1, and the lifting tray 71 is vertically movably provided on the second screw mechanism 72. Furthermore, the lifting tray 71 is horizontally rotatably provided on the second screw mechanism 72, so that the lifting tray 71 can also be rotated outward after being lowered, which is more convenient for the staff to put in or take out the bobbin.

[0039] Embodiment 2

[0040] This embodiment also discloses a wire twisting machine with a ship frame cradle structure.

[0041] Reference Figure 5 , which is different from the first embodiment in that: a distance sensor 43 is also provided on the mounting seat 4 for setting the wire arranging device 42, and the sensing end of the distance sensor 43 faces the bobbin on the wire take-up frame 3, so as to detect the winding progress of the bobbin through the distance sensor 43, and timely remove the bobbin that has been wound up. Furthermore, the distance sensor 43 is movably arranged on the mounting seat 4, and the movement direction of the distance sensor 43 is parallel to the axis of the bobbin. A controller is connected between the distance sensor 43 and the wire arranging control mechanism of the wire arranging device 42. The distance sensor 43 detects the winding condition of the bobbin along the axis direction through movement. If the distance sensor 43 detects that the winding of a certain part of the bobbin is insufficient, the wire arranging device 42 slows down the moving speed the next time it passes through the part, and increases the winding degree of the wire at the part of the bobbin. If the distance sensor 43 detects that the winding of a certain part of the bobbin is too much, the wire arranging device 42 increases the moving speed the next time it passes through the part, and reduces the winding degree of the wire at the part of the bobbin, finally ensuring that the winding condition of each part of the bobbin is consistent and improving the winding quality.

[0042] Reference Figure 5The right side of the mounting seat 4 is provided with a synchronous wheel 44 and a synchronous belt 45. There are two synchronous wheels 44. The two synchronous wheels 44 are spaced apart from each other. The axes of the two synchronous wheels 44 are parallel to the left and right directions of the stranding machine. The synchronous belt 45 is tensioned between the two synchronous wheels 44. The top surface of the synchronous belt 45 is fixedly connected with a first connecting block 81. The first connecting block 81 is fixedly connected to the wire arranging device 42. The bottom surface of the synchronous belt 45 is fixedly connected with a second connecting block 82. The second connecting block 82 is slidably arranged on the mounting seat 4 along the front and rear directions of the stranding machine. The distance sensor 43 is fixedly arranged on the second connecting block 82. By arranging the synchronous wheel 44 and the synchronous belt 45, the wire arranging device 42 moves synchronously with the distance sensor 43 and in opposite directions. It is ensured that after the distance sensor 43 completes a detection along the axis of the bobbin, the wire arranging device 42 can adjust the moving speed of the next round of wire arranging process in time according to the received detection data.

[0043] In other embodiments, a hydraulic pump or the like may be used to replace the first screw mechanism 41 as a wire traversing control mechanism, as long as the moving direction and moving speed of the wire traversing device 42 can be controlled.

[0044] Reference Figure 5 Furthermore, the first connecting block 81 is located below the fourth guide wheel 34 of the cable arranger 42, and a space for the wire to pass through is formed between the first connecting block 81 and the fourth guide wheel 34, thereby limiting the winding of the wire and preventing the wire from escaping from the fourth guide wheel 34. Moreover, since the first connecting block 81 always moves synchronously with the fourth guide wheel 34, the winding of the wire can be limited more stably.

[0045] Embodiment 3

[0046] This embodiment also discloses a wire twisting machine with a ship frame cradle structure.

[0047] Reference Figure 6 , which is different from the second embodiment in that: a counterweight 46 is also slidably provided on the right side of the mounting seat 4, and the counterweight 46 slides along the front-rear direction of the stranding machine, and the counterweight 46 is connected to the bottom of the synchronous belt 45. Through this arrangement, when the wire arranging device 42 moves in one direction, the counterweight 46 moves in another direction, playing the role of a movable counterweight, alleviating the problem that the counterweight of the take-up frame 3 is unstable due to the movement of the wire arranging device 42, thereby causing the take-up frame 3 to shake easily.

[0048] The above are all preferred embodiments of the present invention, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
