Highly reliable lifter system and working method

Abstract

The invention relates to a high-reliability base plate with small volume, light weight, high hardness and not easily deformed. It includes a base plate lifting system and a working method. The needle ruler is fixed, the needle core is embedded in the trocar, the trocar needle core is connected with the trocar moving plate located at the bottom of the bottom plate, the trocar moving plate is connected with the opening and closing trocar swing arm and both are connected on the needle moving positioning block , the cylinder pushes the deep groove ball bearing to slide in the long knife hole of the opening and closing trocar swing arm, so as to push the opening and closing trocar swing arm to swing left and right, once the opening and closing trocar swing arm swings left and right, it will immediately drive the needle moving positioning block Moving left and right, the trocar moving plate correspondingly moves left and right along with the needle moving positioning block, and finally drives the needle core to swing left and right to achieve the opening and closing action, both hooking and releasing yarn.

Description

technical field [0001] The invention relates to a highly reliable bottom plate system and working method with small volume, light weight, high hardness and non-deformation, belonging to the field of textile machinery manufacturing. Background technique [0002] CN201193269, the name "lifting floor", the utility model includes a plate-shaped base body and a number of composite needles installed on the base body, the composite needles are composed of fixed pins fixedly installed on the base body and clearance fit with the fixed pins The movable needles of the fixed needle and the movable needle are all plate-shaped, and are combined to form the plate-shaped composite needle rod of the composite needle, and the plane where the composite needle rod is located is parallel to the plane where the base body is located. The front side of the top of the movable needle is provided with a lateral protrusion, and the top of the fixed needle is a hook bent forward. Its disadvantages are ...

AI Technical Summary

Problems solved by technology

Its disadvantages are as follows: firstly, the method of vertical crochet is adopted. Under the requirement of the mouth space of the flat knitting machine, the margin of the vertical starting needle is relatively small because the needle head is relatively wide. Once the lifting plate is slightly deformed, it is easy to strike the needle Accident; secondly, the volume of the lifting plate corresponding to the vertical lifting needle structure is relatively large, so the convenience of material selection is limited. If the material with relatively high hardness is selected, the specific gravity will be quite large, resulting in relatively large inertia when the lifting plate moves up and down, which is cumbersome. , so we have to choose materials with relatively light materials, the corresponding hardness is relatively low, and it is easy to deform; the third is that the previous computerized flat knitting machines used motors as driving devices, which consume a lot of power and are complicated to install and maintain.
