High-reliability rising bottom board system and working method

Abstract

The invention relates to a high-reliability bottom board having small size, light weight, large hardness and difficult deformation, comprising a rising bottom board system and a working method. A plurality of sleeve needles in the rising bottom board system are arranged in a needle groove of the rising bottom board and fixed by a needle pressing ruler, wherein needle cores are embedded in the sleeve needles, and the sleeve needle cores are connected with a sleeve needle moving board arranged at the bottom of the rising bottom board; the sleeve needle moving board is connected with an open-close sleeve needle swing arm, and both the sleeve needle moving board and the open-close sleeve needle swing arm are connected to a moving needle positioning block. A cylinder pushes a deep groove ball bearing to slide in a long cutter hole of the open-close sleeve needle swing arm so as to push the open-close sleeve needle swing arm to swing left and right. Once the open-close sleeve needle swing arm swings left and right, the moving needle positioning block is immediately driven to move left and right, and the sleeve needle moving board is also correspondingly moved left and right along the moving needle positioning block so as to finally drive the needle cores to swing left and right to achieve open-close actions, namely actions of hooking yarn 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.
