Single-motor-controlled waste-cotton-free bottom lifting device

Abstract

The invention relates to the technical field of knitting equipment, in particular to a single-motor-controlled waste-cotton-free bottom lifting device. A lifting motor of a lifting device assembly drives a threading device assembly to linearly displace longitudinally; a thread rolling wheel motor of the threading device assembly drives a thread rolling wheel with teeth to rotate through a gear; one end of a threading steel wire is fixed to the thread rolling wheel; and the threading steel wire stretches out and draws back to and fro along thread feeding driving wheels and threading needle groups at two ends of a threading bottom plate sequentially. The single-motor-controlled waste-cotton-free bottom lifting device provided by the invention has the beneficial effects that the threading device assembly carries out steel wire receiving-transmitting and control actions; the lifting device assembly is used for enabling the threading device assembly to go up to a nozzle position along lifting guide pillars and go down to a main roller clamping position according to a certain time sequence; and in addition, the threading device assembly of the equipment only needs a single motor to realize telescopic movement of the threading steel wire, so that in the batch production process, the waste cotton cost can be saved, the manual stitch removal work is reduced, and the product production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of knitting equipment, in particular to a single-motor control non-waste yarn bottoming device. Background technique [0002] The starting device of computerized flat knitting machine is a device arranged under the needle bed and used to provide pulling force before the rollers are clamped, because the computerized flat knitting machine must pull the knitted fabric such as clothing pieces to complete subsequent knitting, but The existing lifting device has disadvantages such as complex structure, easy failure, complex structure of the lifting needle plate, waste of yarn, etc. Therefore, it is necessary to improve and optimize the existing lifting device. [0003] The applicant sees the shortcomings of the above-mentioned existing waste yarn bottoming devices, adheres to the spirit of research, innovation and excellence, combines production practice, and uses professional and scientific methods to propose a p...
