Description

Technical Field

[0001] This utility model relates to the field of computerized flat knitting machine technology, specifically to a computerized flat knitting machine head device. Background Technology

[0002] As a core piece of equipment in the modern knitting industry, the stable operation of the machine head unit of a computerized flat knitting machine has a decisive impact on production efficiency and fabric quality. The machine head slide, as a key guiding structure for the movement of the machine head, is in a state of high-speed reciprocating motion for extended periods, easily accumulating fiber debris, oil stains, and environmental dust. These contaminants exacerbate the friction between the slide and the machine head components, leading to increased running resistance, decreased positioning accuracy, and even malfunctions such as machine head collisions and shutdowns.

[0003] In existing technologies, slide rail cleaning mainly relies on manual periodic shutdowns for cleaning, which suffers from low efficiency and incomplete cleaning. Although some equipment uses a simple scraper structure, it is difficult to handle mixed oil stains of different viscosities. Automated slide rail cleaning devices have emerged in the CNC machine tool field, which achieve the cleaning function by using a motor to drive a brush assembly to reciprocate along the slide rail. This design concept provides a technical reference for the cleaning of slide rails in computerized flat knitting machines.

[0004] With the deepening of Industry 4.0 and intelligent manufacturing, computerized flat knitting machines are developing towards higher speed and higher precision, which places higher demands on the cleaning and maintenance of the slide rails. The lack of an effective slide rail cleaning mechanism not only affects the service life of the equipment but also restricts the realization of advanced processes such as full-form knitting. Therefore, developing efficient and reliable head slide rail cleaning technology has become an important research direction for improving the overall performance of computerized flat knitting machines. The brush head of the cleaning unit is always in close contact with the inner wall of the limiting groove, cleaning impurities in the groove in real time and preventing impurities from increasing the rolling resistance of the needle roller bearing or causing jamming. In addition, the cleaning unit is designed with a convenient replacement structure. Simply press the top rod to separate the locking frame from the locking block, and pull the push rod to remove the old brush head for replacement, reducing equipment downtime for maintenance.
