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

Embodiment Construction

[0018] See attached picture. The pulling device described in this embodiment is composed of several rake-type pulling mechanisms on both sides, each rake-type pulling mechanism is independent, and several rake-type pulling mechanisms can be freely selected for action. Each rake-type pulling mechanism includes a claw assembly 3 , a lifting seat 2 and a fixed seat 1 . The gripper assembly 3 includes a gripper seat 31 , the gripper seat 31 and the lifting seat 2 are installed on the linear bearing seat 4 , and the linear bearing seat 4 and the fixed seat 1 are connected by a linear bearing 5 .

[0019] The gripper seat 31 is provided with a plurality of independent gripper pieces 6, and several needles 61 are arranged longitudinally, and are obliquely inserted on the gripper pieces 6 regularly; the front end of the gripper seat 31 is also provided with a guard plate 7, The guard plate is provided with a plurality of elongated slots for needle movement, and the guard plate 7 is i...

Abstract

The invention discloses an adjustable gripper assembly of a knitting machine. The adjustable gripper assembly comprises a gripper base; a plurality of independent gripper pieces are arranged in the gripper base; each gripper piece is provided with a plurality of needles which are obliquely inserted in parallel; each gripper piece is provided with two longitudinally-arranged long kidney-shaped holes; an upper roller pin shaft and a lower roller pin shaft are fixed to the gripper base; the upper roller pin shaft and the lower roller pin shaft penetrate through the two long kidney-shaped holes in each gripper piece respectively, so that each gripper piece is sequentially arranged on the upper roller pin shaft and the lower roller pin shaft in a penetrating mode; a tension spring mounting shaft is further fixed to the gripper seat; a plurality of first tension springs are arranged on the tension spring mounting shaft and are in one-to-one correspondence to the gripper pieces; and one end of each first tension spring is fixed to the tension spring mounting shaft, and the other end of each first tension spring is fixed to the corresponding gripper piece. According to the invention, the gripper assembly is minimally unitized, the gripper pieces are mutually independent, and the long kidney-shaped holes provide spaces for the gripper pieces to continue to move downwards, so that the gripper pieces are located at different traction positions under different knitting requirements.

Description

technical field [0001] The invention belongs to the technical field of knitting machines, in particular to an adjustable claw assembly of the 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 synchr...
