Description

Double cam lace weaving driving device

technical field

The present invention relates to a weft-inserting crochet machine, in particular to a double-cam lace weaving driving device.

Background technique

Generally, it is impossible to directly weave fabrics with tooth edge modification on the weft insertion crochet machine. Even a crochet machine with 8 or more weft yarn bars can only weave complex patterns on the belt surface of the fabric. If you want to weave this beautiful fabric with toothed edges on a weft-inserting crochet machine, you must add a special lace weaving device to the machine. Although there may be a very small number of machines in China that have the device for weaving this tooth edge modification fabric. But their device can only weave the fabric that is symmetrical with tooth edge on two limits of fabric, and the tooth edge that weaves out is very little, and effect is very inconspicuous. And their device structures are extremely complicated, cost is high, installation and adjustment are very inconvenient, and the structure is unstable. When customers change different types of fabrics, their devices may be difficult to meet customers' weaving needs.

When the customer is using the 0-400mm stroke long weft drive device to weave wider fabrics. If there is no auxiliary weft pressing device installed on both sides of the fabric. , because the stroke of the weft yarn bar is relatively long, the weft yarn tension is relatively loose, so the weft yarn cannot be fed into the warp often. Thereby seriously affecting the production efficiency and product quality of customers in the production of relatively wide fabrics.

Contents of the invention

The purpose of the present invention is to overcome the above problems existing in the prior art, and to provide a double-cam lace weaving driving device. The present invention overcomes the technical difficulty of having different tooth edge decorations on both sides of the same fabric, and also improves the quality of the tooth edge decoration fabrics at the same time. The quality of the braided teeth is larger and the effect is more obvious.

In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the present invention is realized through the following technical solutions:

Double-cam lace weaving driving device, including the main shaft of the machine connected to the first transmission part, the first transmission part connected to the second transmission part, the second transmission part connected to the drive shaft, and one end of the drive shaft is supported by the cam drive The other end is connected with two curved cams, and a rocker support seat is provided on one side of the cam driving support seat, and the rocker support seat is connected with two crank rockers through the central axis of rocker rotation. The two crank rockers are all connected with the connecting rod, and the connecting rod is connected with the tooth edge looping weft needle through the driving control shaft of the tooth edge looping weft needle.

Further, both ends of the connecting rod are provided with joint bearings.

Further, one end of the crank rocker is arranged under the curved cam, and is connected to the curved cam, and the other end is connected to the compression spring, and the compression spring is connected to the spring fixing seat, and the spring fixing seat is fixed to the cam driving support seat top.

Further, a lubricating oil groove is provided on the cam drive support seat below the drive shaft.

Further, the drive control shaft of the tooth edge looping weft needle is connected to the bearing mounting seat, and a weft needle mounting seat is arranged between the tooth edge looping weft needle drive control shaft and the tooth edge looping weft needle. A clamping connection block is arranged between the edge looping weft needle driving control shaft and the connecting rod.

The beneficial effects of the present invention are:

1. The present invention can effectively meet the needs of the market for weaving various types of fabrics with tooth edge modification on weft-inserting crochet machines. The use of high-precision double-cam drive effectively overcomes the technical difficulties of asymmetrical or different types of edge modification on the same fabric.

2. The present invention uses a synchronous pulley and a high-precision curved cam to control and transmit power. Therefore, the mechanical properties of all aspects of the mechanism are very superior, which makes the production efficiency of the equipment high and the product quality stable. Moreover, the installation, debugging, product replacement and follow-up equipment maintenance of this mechanism are extremely convenient. Moreover, this mechanism adopts specially designed weft looping weft needles, which makes the tooth loops of the fabric more beautiful, the tooth edges look larger, and the effect of tooth edge modification is clearer and more obvious.

3. At the same time, using this mechanism can also effectively assist customers in weaving wider fabrics. When the customer is using the 0-400mm stroke long weft drive device to weave wider fabrics. When the machine is weaving fabrics, this device is used to control the weft yarn moving to both sides of the fabric with the looping weft needle according to the effective time of the cam, so that it can effectively help the weft yarn to be fed into the warp. In this way, the customer can effectively improve the production efficiency and product quality of the customer when producing and weaving wider fabrics.
