A pulling device for a knitting machine

Abstract

The invention discloses a pulling device for a knitting machine, which comprises several rake-type pulling mechanisms, each of which includes a gripper assembly, a lifting seat and a fixing seat, the gripper assembly includes a gripper seat, a gripper The claw seat and the lifting seat are installed on the linear bearing seat. There are multiple independent claw pieces inside the claw seat, and each claw piece is provided with a number of needles inserted in parallel and obliquely; the claw piece is provided with two There are two long waist holes arranged longitudinally, the upper needle roller shaft and the lower needle roller shaft are fixed on the gripper seat, and each gripper piece is passed on the upper needle roller shaft and the lower needle roller shaft in turn; the gripper seat is also fixed There is an extension spring installation shaft, and a plurality of first extension springs are arranged on the extension spring installation shaft, and the first extension springs correspond to the claw pieces one by one. The present invention minimizes the gripper assembly, each gripper piece is independent of each other, and the long waist hole on the gripper piece enables each gripper piece to be in a different pulling position under different weaving requirements.

Description

technical field [0001] The invention belongs to the technical field of knitting machines, and in particular relates to a pulling device of a knitting machine. Background technique [0002] At present, the rake-type pulling device used on the knitting machine is used to pull the fabric, especially on the fully formed machine, each rake-type pulling mechanism in the rake-type pulling device works independently, and can be adjusted according to the specific weaving requirements of the fabric. Freely choose the rake-type pulling mechanism for action, which can be pulled on both sides, single side, or a part of one side, or even a single pull, to achieve selective pulling of the fabric, and the pulling force is Controllable, according to the pulling requirements of different fabrics, adjust the air pressure and the electric control mechanism to adjust the pulling force. [0003] Multiple grippers on a single rake-type pulling mechanism will grab a certain width of fabric synchro...

AI Technical Summary

Problems solved by technology

[0003] Multiple grippers on a single rake-type pulling mechanism will grab a certain width of fabric synchronously. When the fabric grasped by a single rake-type pulling mechanism has both woven and non-woven parts, if the grippers continue to pull down If the fabric is pulled, the non-woven part of the fabric coil will be stretched, which will affect the forming quality of the fabric

If the gripper stops pulling the fabric downward, the part of the fabric to be woven will be blocked at the needle plate opening, which will affect the knitting work and the forming quality of the fabric
