Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a cable stranding machine. Background Art

[0002] With the rapid development of the cable industry, the demand for cable stranding machines is increasing day by day. In order to improve production efficiency, a horizontal stranding machine is generally used to strand cables at present. Since the area of the middle wire loading disc of the horizontal cable stranding machine is relatively long, it is very easy to generate jumping during operation, and the stable rotation of the rotating body cannot be guaranteed. At the same time, during braking, due to the relatively long area of the middle wire loading disc, the lateral torque of the machine body is relatively large due to inertia, which is easy to cause damage to the machine body. At the same time, when the existing stranding machine brakes, the braking effect is slow and the safety is not good.

[0003] Therefore, it is necessary to design a cable stranding machine to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cable stranding machine aiming at the deficiencies of the prior art.

[0005] The technical solution of the utility model is: a cable stranding machine, including a frame and a rotating shaft rotatably installed on the frame; a plurality of fixed discs are evenly distributed on the rotating shaft; a plurality of wire dispensing racks are circumferentially distributed between two adjacent fixed discs; a plurality of roller devices abutting against the fixed discs are evenly distributed on the edges of all the fixed discs, and the roller devices are in rolling connection with the fixed discs.

[0006] The roller device includes a fixed seat and a roller rotatably installed on the fixed seat; an elastic member for abutting against the fixed disc is arranged on the outer side of the roller.

[0007] The elastic member is an inflatable tire.

[0008] The roller is rotationally connected to the fixed seat through a mounting shaft; a brake disc is fixed on one side of the mounting shaft where the roller is located; a brake for braking the brake disc is arranged on the edge of the brake disc.

[0009] A sensor for detecting the rotation speed of the roller is arranged on the fixed seat; both the sensor and the brake are connected to an ABS controller.

[0010] Adopting the above technical solution, the utility model has the following beneficial effects: A plurality of roller devices abutting against the fixed disk are evenly distributed on the edge of the fixed disk in the middle of the utility model, and the roller devices are in rolling connection with the fixed disk. Through the limitation of the fixed disk by the roller devices, the roller devices can always keep in contact with the fixed disk without gaps, which can not only prevent the cable from jumping during the stranding process, reduce the rotational inertia at both ends of the machine body, thus ensuring the stable rotation of the rotating body, but also avoid the damage of the machine body caused by the existence of lateral inertia when the machine body brakes. In addition, the roller devices can also play a good role in protecting the bearings at both ends of the rotating shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] (Embodiment 1)

[0017] See Figure 1 and Figure 2 , A cable stranding machine of this embodiment includes a frame 1 and a rotating shaft 2 rotatably installed on the frame 1; A plurality of fixed disks 3 are evenly distributed on the rotating shaft 2; A plurality of wire pay-off frames 4 are circumferentially distributed between two adjacent fixed disks 3; A plurality of roller devices 5 abutting against the fixed disks 3 are evenly distributed on the edges of all the fixed disks 3, and the roller devices 5 are in rolling connection with the fixed disks 3.

[0018] Furthermore, in order to facilitate the installation of the roller device 5, the roller device 5 includes a fixed seat 5-1 and a roller 5-2 rotatably installed on the fixed seat 5-1; As a preference, three roller devices 5 corresponding to each fixed disk are provided and are arranged at 120° to each other, so as to ensure the limiting effect on the fixed disk 3 and avoid the jumping of the limiting disk; An elastic member abutting against the fixed disk 3 is arranged on the outer side of the roller 5-2, ensuring the stability of the contact between the roller 5-2 and the fixed disk 3.

[0019] Furthermore, the elastic member is an inflatable tire, which reduces the wear of the elastic member and can always keep the elastic member against the fixed disk 3, with better limiting effect.

[0020] Furthermore, to facilitate the deceleration of the fixed disk 3, the roller 5-2 is rotatably connected to the fixed seat 5-1 through a mounting shaft; a brake disk 5-3 is fixed on one side of the mounting shaft where the roller 5-2 is located; a brake 5-4 for braking the brake disk 5-3 is provided at the edge of the brake disk 5-3.

[0021] Furthermore, a sensor for detecting the rotation speed of the roller 5-2 is provided on the fixed seat 5-1; preferably, the brake 5-4 can be similar to the brake used in vehicles, and both the sensor and the brake 5-4 are connected to the ABS controller to prevent the roller 5-2 from locking, improving the service life of the roller 5-2. At the same time, an ABS control system is set up, and its braking effect is several times faster than that of the original equipment. At the same time, when braking emergently, ABS can play a good protective effect on the equipment.

[0022] In the utility model, a plurality of roller devices 5 abutting against the fixed disk are evenly arranged on the edge of the fixed disk 3 in the middle, and the roller devices 5 are in rolling connection with the fixed disk 3. Through the limitation of the fixed disk 3 by the roller devices 5, the roller devices 5 can always keep in contact with the fixed disk 3 without gaps, which can not only prevent the cable from jumping during the stranding process, thus ensuring the stable rotation of the rotating body, but also avoid the body damage caused by the lateral inertia during the body braking. In addition, the roller device can also play a good protective role for the bearings at both ends of the rotating shaft.
