Description

Technical Field

[0002] As a metal wire processing machine, the double twist machine has the advantages of high efficiency and compact structure. The double twist machine is usually divided into two types: the external-inward type and the internal-outward type. Both types have a cradle frame and a left and right rotating shaft structure, namely the flywheel disc spindle. The left and right flywheel disc spindles are connected to the cradle through the cradle frame bearing seats at both ends. During operation, the flywheel disc spindle rotates while the cradle frame does not rotate, thereby twisting the wire bundle.

[0003] The spindle drive mechanism in the prior art includes: a motor, a transmission shaft and a synchronous belt transmission mechanism, wherein the transmission shaft is driven by a motor to rotate, and the synchronous belt transmission mechanism drives the two flywheel spindles to rotate. Since the transmission shaft is too long, the energy consumption of the motor is large when it is running, and when the motor is installed with the transmission shaft, it will occupy a large external space. Utility Model Content

[0004] The purpose of the utility model is to provide a high-speed rotation drive mechanism for the flying wing main shaft of a steel cord double-twist machine. By designing a dual-output shaft motor as a driving force, the advantages of low energy consumption and good rotation synchronization are achieved, and the problem of occupying a large external space when the above-mentioned motor is installed with a transmission long shaft is solved.

[0005] In order to solve the above technical problems, the utility model provides a high-speed rotation drive mechanism for a flying wing main shaft of a steel cord double twisting machine, comprising:

[0007] Active pulleys are distributed on the left and right sides and are drivingly connected to the two output ends of the driving motor;

[0008] A driven pulley is sleeved on the flying wing main shaft, and the flying wing main shaft is rotatably mounted on the side wall of the frame through a bearing;

[0009] A synchronous belt is wound around the driving pulley and the driven pulley.

[0010] Preferably, the dual-output shaft motor is a permanent magnet synchronous motor.

[0011] Preferably, it also includes a coupling, a transmission shaft and a bearing seat; the transmission shaft is rotatably mounted on the left and right bearing seats, one end of the transmission shaft is connected to the right output end of the drive motor through the coupling, and the other end is sleeved with the driving pulley.

[0012] Preferably, the coupling is a diaphragm coupling.

[0013] Preferably, it further comprises a tensioning pulley, which is rotatably mounted on the frame, and the mounting position can be linearly adjusted so that the tensioning pulley can tension the synchronous belt.

[0014] Preferably, the driving pulley is a large-toothed pulley, and the driven pulley is a small-toothed pulley.

[0015] Preferably, it also includes an encoder, which is installed on the shaft end of the right driving pulley.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The utility model achieves the advantages of low energy consumption and good rotation synchronization by designing a dual-output shaft motor as the driving force, which can ensure the accuracy of the rotation synchronization of the two flying wing main shafts, and the dual-output shaft motor is arranged and installed in the space at the bottom of the frame, without the problem of occupying external installation space; and when in use, the rotation speed of the active pulley can be measured by the encoder, so as to facilitate the precise adjustment of the rotation speed of the dual-output shaft motor.
