Intermittent feeding mechanism for yarn

Abstract

The invention discloses an intermittent feeding mechanism for yarn and belongs to the field of mechanical equipment for yarn conveying processing. A yarn reel of the mechanism horizontally sleeves a yarn release rotation roller, a damping press wheel is vertically and rotatably connected to one side of a press cylinder guide block, and a damping compression spring is obliquely arranged between a press cylinder guide block and a feeding support; a yarn pulling conveying belt is horizontally arranged at one side of the feeding support, a yarn pulling gear and an intermittent gear are alternatively meshed with each other, and the output end of a yarn pulling motor is in transmission connection with the intermittent gear through a yarn pulling belt; multiple yarn bearing press rollers are rotatably connected to the upper side of a yarn bearing lifting plate of the output end of a yarn bearing air cylinder in the horizontal direction in sequence, multiple press belt rotation rollers are rotatably and horizontally connected to the lower side of a press belt fixing plate in the horizontal direction in sequence, and a roller clamping mechanism is vertically arranged at one side of an auxiliary yarn pull rotation roller. The intermittent feeding mechanism for the yarn is reasonable in structural design, the yarn can be efficiently and conveniently drafted and conveyed segment by segmentand can be automatically, stably and intermittently fed, and the demands of processing and application are met.

Description

technical field [0001] The invention belongs to the field of yarn conveying and processing machinery, and in particular relates to a yarn intermittent feeding mechanism, which is mainly used for automatic segmental conveying of yarn. Background technique [0002] With the development of the production industry and the improvement of people's living standards, people have higher and higher requirements for textile materials. High-end textiles can be woven from high-quality textile materials to meet people's needs. Textile materials refer to fibers and fiber products, which are specifically manifested as fibers, yarns, fabrics and their composites. In modern textiles, the research and development of new textile materials, especially the development and use of nanofibers, has broken through the traditional textile materials. Conceptually, textile materials have become an important component of soft matter materials. Yarn is an important textile material. Yarn refers to a produ...

Problems solved by technology

In the process of yarn production and processing, in order to facilitate the production, storage, sales and transportation of yarn, the processed yarn is stored in the form of yarn reels. For unwinding and conveying, it is necessary to continuously convey and load the chemical fiber bobbin yarn. During the unwinding and conveying process of the existing yarn reel, it is difficult for the yarn reel wound with the yarn to rotate and unwind smoothly and evenly, and now During the conveying process of some yarns, the yarns cannot be accurately pulled and conveyed in sections according to the needs, and it is difficult to realize the automatic intermittent feeding of the yarns, which cannot meet the needs of production and use.
