Description

Knocking-over needle bed for straw bundling net warp knitting machine

Technical Field

The utility model relates to a warp knitting machine, in particular to a knocking-over needle bed for a straw bundling net warp knitting machine.

Background

Referring to fig. 1 and 2, in operation, the latch needle a follows the motion track of the latch needle bed B and moves up and down in the tooth space C-1 of the knocking-over needle bed C to weave. When the needle head is lowered to be lower than the edge used for knocking over at the top of the knocking over needle bed C, the old coil is blocked by the old coil, so that the old coil is knocked off from the needle head, at the moment, the latch needle is pulled, if the pulling force applied to the latch needle is large, the tooth socket exists, the latch needle can be prevented from being pulled and deviating from the position, the knitted fabric coil can be prevented from being bent and twisted, and in addition, the latch needle can be prevented from being pulled and broken.

In order to overcome the advantages of the tooth socket C-1, the existing knocking-over needle bed C processes a plurality of tooth sockets C-1 for mounting knitting needles at set intervals by using a milling machine after processing a needle bed plate, as shown in FIG. 4, and in order to avoid the needle socket of the latch needle bed from touching the tooth C-2 of the knocking-over plate when the latch needle rises to the highest point, the width of the lower part of the tooth C-2 is smaller than the width of the upper part of the tooth C-2, as shown in FIG. 3.

The knockover needle bed with the structure has the following defects in the processing process: (1) the knockover needle bed with the tooth grooves has the advantages that firstly, the material cost is high, secondly, the machining difficulty is increased by milling the tooth grooves, and the uniform size of the tooth grooves is difficult to ensure, so that the production cost is high; (2) the end of the tooth of the knock-over needle bed with tooth grooves easily scrapes the yarn when the fabric knocks over, resulting in yarn breakage.

Therefore, when a light-weight net such as a straw net needs to be woven, the needle bed with the knockover structure is simple in structure, easy to process and low in cost.
