Weaving machine transmission and weaving machine position automatic calibration system driven by switch reluctance motor

Abstract

The invention provides a weaving machine transmission and weaving machine position automatic calibration system driven by a switch reluctance motor. A motor stator of the switch reluctance motor is fixedly arranged on a machine frame, the motor rotor is fixedly connected with a main motor gear shaft supported on the machine frame through a bearing, one end of the main motor gear shaft is connected with a piston through a bearing, and the piston is fixedly connected with a movable insertion pin arranged in a guide hole formed in the machine frame, so the insertion pin forms cylinder pair connection with the machine frame, the piston is arranged in a piston cylinder fixedly arranged on the machine frame, in addition, the cylinder pair connection is formed, the piston is matched with the insertion pin, and can transversely move but cannot rotate; the main motor gear shaft is engaged with an opening transmission gear fixedly connected onto an opening transmission shaft through a shaft gear, the opening transmission shaft is fixedly connected with an armature of an opening brake through a spring, the two ends of the opening transmission shaft are respectively connected with an encoder and an opening mechanism, and a coil of the opening brake is fixedly connected with the machine frame. The weaving machine transmission and weaving machine position automatic calibration system has the characteristics that the mechanism is reasonable, the use is convenient and reliable, the speed of a weaving machine can be accelerated, the speed change and position calibration automation degree of the weaving machine can be improved, and the like.

Description

technical field [0001] The invention relates to a loom transmission and loom position automatic calibration system driven by a switched reluctance motor, and a transmission and control technology in the field of textile machinery. Background technique [0002] Conventional rapier looms use a three-phase asynchronous AC motor to drive the main shaft of the loom, and a clutch brake is used to realize the starting and braking function of the loom. The speed of the loom is changed by changing the speed ratio or changing the driving frequency of the motor. [0003] figure 1 Shown is a transmission system in the prior art, wherein, the output shaft of the three-phase asynchronous AC main motor 1 is fixedly connected with the main drive pulley 2; the main clutch rotor 7 is fixedly connected with the main drive pulley 4, and is connected with the The high-speed gear shaft 11 is connected; the clutch brake armature 8 is fixedly connected to the high-speed gear shaft 11 through a spr...

Problems solved by technology

[0012] But the above-mentioned existing transmission system has the following defects: when the loom speed reaches or exceeds about 450-500 rpm and the loom starts to brake, the main clutch and main brake fail frequently, or when the load of the open transmission system is very large , slow train, frequent failures of the weft-seeking clutch, broken transmission belt, etc., which limit the maximum speed of the loom; if the speed of the loom is changed, the pulley needs to be replaced or the frequency conversion motor is used, and variable-speed weaving cannot be realized. Normal weaving and weft-seeking movement , Slow motion adopts different transmission routes, and the mechanical structure is complex; the zero position of the spindle encoder representing the position of the loom needs to be manually calibrated
