Description

Technical Field

[0001] This utility model relates to the field of untwisting machine technology, specifically a novel horizontal untwisting machine. Background Technology

[0002] As the name suggests, the horizontal untwisting machine is designed to operate in a horizontal position. It is mainly used for untwisting the total stranding of high-frequency digital cables, ensuring that the relative positions of the insulated core wires are staggered and balanced during the total stranding process. This overcomes the problem of uneven torsional stress during the total stranding process, ensuring uniform stranding quality and precise pitch. In addition, the horizontal untwisting machine also plays an important role in many industries such as shipbuilding, automobile manufacturing, aerospace, plastics processing, wire and cable manufacturing, and railway maintenance.

[0003] A fiber optic detwisting machine, referenced in announcement number CN217478763U, includes a pay-off mechanism, a take-up mechanism, a detwisting mechanism, and a visual inspection mechanism. The pay-off and take-up mechanisms are spaced apart along a straight line, and a fiber optic inspection area is formed between them for the fiber to naturally droop. The visual inspection mechanism is located in the fiber optic inspection area. The pay-off mechanism includes a pay-off reel, a first driving device, an auxiliary traction device, and a pay-off tension device. The take-up mechanism includes a take-up reel and a second driving device. The detwisting mechanism includes a rotating table and a third driving device. The visual inspection mechanism includes a first camera and a second camera. This fiber optic detwisting machine solves the technical problem in existing fiber optic detwisting mechanisms that cannot automatically detect the degree of fiber twisting and accurately detwirl. As can be seen from the above, although this detwisting machine can be applied well, it is usually not convenient to perform multi-stage deceleration on the pay-off and take-up components, making it difficult to accurately detwirl the cable. Therefore, the detwisting accuracy of this machine is still difficult to achieve the expected result, which often troubles users. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of horizontal untwisting machine to solve the problem mentioned in the background art that although the untwisting machine can be used well, it is usually not convenient to perform multi-stage deceleration on the winding and unwinding parts, which makes it difficult to accurately perform untwisting operations on cables, so that the untwisting accuracy of the untwisting machine is still difficult to achieve the expected results.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel horizontal unwinding machine includes a base plate, a base plate on one side of the top of the base plate, a portal frame on one side of the top of the base plate, a transmission frame on the top of the portal frame, a second rotary drive member installed on the inner wall of the transmission frame, one end of the second rotary drive member extending to the outside of the transmission frame and having a first gear, a second gear rotatably installed on the outer wall of the transmission frame on one side of the first gear, the second gear meshing with the first gear, a third gear on the outer wall of the second gear away from the transmission frame, a fourth gear rotatably installed on the outer wall of the transmission frame on the side of the third gear away from the first gear, the fourth gear meshing with the third gear, a linkage shaft on the outer wall of the fourth gear away from the transmission frame, a base on the end of the linkage shaft away from the fourth gear, a reduction motor installed on one side of the top of the base, and a take-up and unwinding roller rotatably installed on the top of the base on the side of the reduction motor via a bracket.

[0006] Preferably, one end of the geared motor is provided with a drive wheel, and one end of the take-up and untake-down roller is provided with a driven wheel. A transmission belt is wound on the outer wall between the driven wheel and the drive wheel. The transmission belt is provided so that the driven wheel drives the driven wheel to rotate when the drive wheel rotates.

[0007] Preferably, a first rotary drive component is installed at the top of the bottom plate on one side of the substrate. The bottom end of the first rotary drive component penetrates the bottom plate and is provided with a linkage arm. The first rotary drive component is provided so that the linkage arm can be driven to rotate slightly.

[0008] Preferably, a component rack is rotatably mounted on the bottom end of the base plate on both sides of the linkage arm. A first motor is mounted on the inner wall of the component rack. One end of the first motor extends to the outside of the component rack and is provided with a front roller. The first motor is configured to drive the front roller to rotate.

[0009] Preferably, a second motor is mounted on the bottom end of the base plate on one side of the mounting rack via a bracket. A rear roller is mounted on one end of the second motor, so that the rear roller can be driven to rotate.

[0010] Preferably, two steering arms are rotatably mounted on the end of the linkage arm away from the first rotary drive member. The end of the steering arm away from the linkage arm is movably connected to the outer wall of the mounting frame. A guide roller is rotatably mounted on the top of the bottom plate on the side of the first rotary drive member away from the substrate through a bracket. The guide roller is set to guide and limit the cable during the winding and unwinding process.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the new horizontal untwisting machine not only achieves the purpose of accurately untwisting the cable, but also ensures the untwisting effect of the cable when using the untwisting machine, and improves the convenience of transporting the untwisting machine.

[0012] (1) The first gear is driven to rotate by the second rotary drive component. Since the first gear and the second gear mesh with each other, and the third gear and the fourth gear mesh with each other, and the diameters of the first gear and the third gear are smaller than the diameters of the second gear and the fourth gear respectively, the first gear drives the second gear to rotate slowly, and the second gear drives the fourth gear to rotate further slowly through the third gear, so that the fourth gear drives the base to rotate synchronously through the linkage shaft, which can drive the winding and unwinding component at the top of the base to rotate in a multi-stage deceleration manner, thereby achieving the purpose of accurately unwinding the cable;

[0013] (2) The drive wheel is driven to rotate by a geared motor, so that the drive wheel drives the driven wheel to rotate slowly via a transmission belt, so that the driven wheel drives the take-up and unwinding rollers to rotate synchronously, so that the take-up and unwinding rollers can slowly unwind the cable on its outer wall, or slowly wind the cable, thereby ensuring the unwinding effect of the cable when the unwinding machine is used.

[0014] (3) The linkage arm is driven to rotate slightly by the first rotary drive component, so that the linkage arm drives the placement frame to rotate at the bottom of the base plate via the steering arm. This can adjust the direction of the front roller. Then, the front roller is driven to rotate by the first motor, and the rear roller is driven to rotate by the second motor. This allows the rear roller and the front roller to slide on the ground, so as to electrically transport the entire untwisting machine, thereby improving the convenience of untwisting machine transfer.

The top of the bottom plate 1 on the side of the first rotary drive member 6 away from the base plate 8 is rotatably mounted with a guide roller 7 through a bracket.

[0028] In use, the guide roller 7 is set to guide and limit the cable during the winding and unwinding process;

[0029] A portal frame 9 is provided on one side of the top of the substrate 8. A transmission frame 12 is provided at the top of the portal frame 9. A second rotary drive member 13 is installed on the inner wall of the transmission frame 12.

Finally, the second rotary drive 13 drives the first gear 14 to rotate, causing the first gear 14 to drive the second gear 15 to rotate slowly. The second gear 15 then drives the fourth gear 17 to rotate slowly via the third gear 16, so that the fourth gear 17 drives the base 10 to rotate synchronously via the linkage shaft 18. This drives the take-up and unwinding components at the top of the base 10 to rotate in a multi-stage deceleration manner, precisely untwisting the cable according to its torque, thus completing the use of the untwisting machine.
