Description

Technical Field

[0001] This utility model relates to the field of glass fiber drawing machine technology, and in particular to a direct-drive main shaft mechanism for a reciprocating glass fiber drawing machine head motor. Background Technology

[0002] A glass fiber drawing machine is a high-speed mechanical device that draws molten glass into fiber filaments and winds them into fiber rolls according to a certain pattern.

[0003] Currently, the main shaft mechanism of glass fiber drawing machines on the market generally adopts the method of fixing the motor rotor on the main shaft and placing the motor stator on the motor housing, plus parts such as the speed measuring disk to control the rotation of the main shaft. This structure has a complex main shaft processing technology, requires high installation accuracy, is not easy to install, and is prone to cumulative errors during installation, which can easily cause large vibrations in the machine head and low rotation accuracy. Once the motor stator or rotor has a problem during production and needs to be taken offline for repair, the workload is large and production is affected, causing unnecessary losses to the drawing company.

[0004] The spindle support consists of two support wheel sets, one at the front and one at the back, mounted in support wheel seats on the turntable and the other on the tilting pulley. Each support wheel set has four nylon support wheels evenly distributed around the circumference of the spindle, providing radial support. The two support wheel sets horizontally support the spindle, and the nylon wheels provide support during the spindle's reciprocating motion. This structure is costly, has complex assembly and adjustment processes, is difficult to ensure assembly precision, and has poor overall rigidity. Utility Model Content
