Resistance gripper for yarn feeding device

This creation relates to a gripper, especially a resistance type gripper for a yarn feeding device.

With the continuous development of the textile industry, more and more textile machinery must have the demand to supply irregular yarn feeding, in order to adapt to the weaving of the fabric pattern and the tension of the cloth surface, so as to meet the demand for yarn supply. In particular, the strip type yarn feeding device does not need to use an active motor, but uses a strip provided on the knitting machine as a power source, which simplifies the mechanism, reduces the volume, and reduces the cost.

The yarn feeding device is provided with a yarn storage wheel, and the yarn can be wound around the yarn storage wheel to drive the pulley by a belt member such as a belt (not shown), and then the storage yarn is rotated through the transmission shaft to utilize the yarn storage wheel. The yarn is driven to store and feed the yarn.

Conventional yarn feeding devices are provided with a gripper which can be clamped to the yarn by a gripper to make the yarn conveyance relatively stable. Most of the conventional grippers use magnet adsorption or spring to push the gripping elements. The gripper can only provide a fixed resistance, and the resistance cannot be changed according to different conditions, so that the yarn conveying is unstable. Moreover, it is also inconvenient for the conventional gripper to penetrate the yarn.

The reason is that this creator feels that the above-mentioned deficiency can be improved. He is devoted to research and cooperates with the application of theory, and finally proposes a creation that is reasonable in design and effective in improving the above-mentioned deficiency.

The main purpose of this creation is to provide a resistance type gripper for the yarn feeding device, which can automatically adjust the resistance, make the yarn conveying more stable, and penetrate The operation of the yarn is also relatively simple and easy.

In order to achieve the above object, the present invention provides a resistance type gripper for a yarn feeding device, the gripper being disposed on a yarn feeding device, the gripper comprising: a first yarn clamping member having a plurality of first jaws a second yarn clamping member disposed on one side of the first yarn clamping member, the second yarn clamping member having a plurality of second jaws, the second jaws being disposed in an interlaced manner with the first jaws; And an elastic member, the top of which abuts the second yarn clamping member, so that the first yarn clamping member and the second yarn clamping member form an elastic clamping.

This creation has the following beneficial effects: The first yarn-carrying member and the second yarn-clamping member of the present yarn gripper provide the elastic force of the clamping with the elastic member to achieve the effect of clamping the yarn, and the yarn conveying is relatively stable. The first and second grip members have a plurality of first jaws and a plurality of second jaws, and the yarn is clamped between the first jaws and the second jaws. It can automatically adjust the resistance to make the yarn delivery more stable.

The yarn gripper of the present invention does not require time-consuming and laborious threading operation, and the yarn can be directly pushed into the open end of the first yarn-carrying member and the second yarn-clamping member, so that the yarn can be clamped to the first clamp. Between the yarn member and the second yarn-carrying member, the operation of threading the yarn is relatively simple and easy.
