Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a cable production stranding device with a noise reduction function. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. One of the processing procedures of cables is inseparable from the stranding machine, which is a common and indispensable thing in daily life. On the stranding machine, the metal wires are arranged in a regular spiral shape around the center line of the strand core according to technical requirements to twist the rope strands. When the existing stranding machine is twisting the optical cable, the multiple sub-wires at the incoming line swing randomly, which can easily hurt the operator. The cable is prone to static electricity and dust absorption due to friction, resulting in a decrease in the cable conduction quality. At the same time, when the drive motor is running, it generates noise due to vibration, which puts the operator in a noisy environment.

[0003] For example, Chinese patent publication No. CN214328284U discloses a twisting device for cable production. When in use, the sub-wires of the cable are passed through the incoming wire buffer device and worn on the twisting machine body. The twisting machine body twists the sub-wires into cables, and the cables are wound onto the traction wheel. The drive motor is started to drive the traction wheel to pull the cable. The rotation of the drive motor generates vibration, compresses the buffer spring, and the first limit rod swings along the limit groove, reducing the occurrence of noise generated by the traditional drive motor, thereby achieving the effect of buffering and noise reduction; when the sub-wire is swung through the incoming wire buffer device, the incoming wire buffer device performs shock absorption and buffering to prevent the cable sub-wires from hurting others due to swinging when twisting, thereby achieving the effect of protecting the operator; under the action of the static electricity elimination device, the static electricity of the cable is eliminated.

[0004] However, the cable stranding equipment used in the above application uses a buffer spring to reduce the noise of the traction drive motor, but this will cause the traction wheel to shake, thereby affecting the loosening of the cable bundle, and generally the main noise comes from the noise generated by the operation of the twisting machine body. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a cable production stranding equipment with noise reduction function. Utility Model Content

[0006] The purpose of the utility model is to provide a cable stranding device with a noise reduction function for cable production, so as to solve the problem that the cable stranding device proposed in the above-mentioned background technology reduces the noise of the traction drive motor through a buffer spring, but causes the traction wheel to shake, thereby affecting the loosening of the cable bundle, and generally the main noise comes from the noise generated by the operation of the twisting machine body.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a twisting device for cable production with noise reduction function, comprising a bearing seat and a support seat, the support seat is installed on the right side of the bearing seat, a twisting device is arranged on the left side of the bearing seat, and a lubrication device is arranged on the left side of the support seat.

[0008] The stranding device comprises a noise reduction unit and a stranding unit.
