Electromechanical system and method for automatic spinneret-plate shoveling

Abstract

The invention relates to an electromechanical system for automatic spinneret-plate shoveling. The system includes a first power set, a second power set, at least one shovel blade component mounting base, a shovel blade component, a position sensor and a control unit. The first power set drives the second power set to do up and down linear reciprocating motion through a screw nut driving pair, andthe shovel blade component mounting base is coaxially fixed on an output shaft of the second power set to drive the shovel blade component to do rotational motion. The control unit collects signals from the position sensor and a cutter base assembly sensor and completes corresponding signal processing to perform corresponding control processes. A method of mechanical and electrical combination isadopted, the rapidity and accuracy of automatic tool setting are ensured through a mechanical buffering and sensing detection control technology, and the high efficiency of automatic operation of spinneret-plate shoveling is embodied and guaranteed.

Description

Technical field [0001] The invention relates to the field of chemical fiber mechanical spinning production, in particular to the shovel automation technology of the spinneret. Background technique [0002] In the process of chemical fiber spinning, the surface of the spinneret adheres to polymer, which affects the spinning quality. Generally, a shovel is completed on the spinneret surface every 24 hours. At present, the manual shovel method is mainly used. The worker holds a shovel. The spinneret surface is quickly cleaned, the manual shovel method is labor intensive, the working environment causes great damage to the fitness of the workers, and the manual shovel is very dependent on skilled workers, all of which cause the cost of the manual shovel to increase. The higher the increase, the more difficult it is to recruit workers. Therefore, the automation of spinneret cleaning is imperative. At present, some manufacturers or patented shoveling devices are being developed, but mos...

[0002] In the process of chemical fiber spinning, the surface of the spinneret adheres to polymers, which affects the spinning quality. Generally, the spinneret surface needs to be shoveled every 24 hours. At present, the manual shoveling method is mainly used, and the worker holds a shovel The rapid cleaning of the spinneret surface, the manual shoveling method is labor-intensive, the working environment has great damage to the fitness of the workers, and the manual shoveling is very dependent on skilled workers, all of which lead to the cost of manual shoveling. It is getting higher and higher, and it is more and more difficult to recruit workers. Therefore, the automation of spinneret cleaning is imperative. At present, there are some manufacturers or patents showing that automatic scraping devices are being developed, but most of them only solve how to realize automatic cleaning. Regarding the scraper problem, there is little research on how to quickly attach the scraper to the spinneret surface and maintain a certain scraper force
