Abstract

The utility model relates to the textile field, in particular to a yarn clamping mechanism. The yarn clamping mechanism comprises a main motor, a cam, a large rocker, a large rocker supporting column, a pulling rod, a spring supporting plate, a reset spring which is located between the spring supporting plate and a check ring, the check ring which is arranged on the pulling rod, a first clamping piece, a rotating shaft, a rotating shaft support, a second clamping piece, a yarn clamping sleeve and a yarn clamping anvil roller. A rotating shaft of the main motor is connected with the cam. The large rocker can rotate around the large rocker supporting column and is connected with the pulling rod in a rotating mode. The spring supporting plate is connected on a machine frame in a rotating mode and is connected with the pulling rod in a sliding mode. The first clamping piece is connected with the pulling rod in a rotating mode and is fixedly connected with the rotating shaft. The rotating shaft is arranged in the rotating shaft support in a penetrating mode and is connected with the rotating shaft support in a rotating mode. The second clamping piece is fixedly connected with the rotating shaft and is connected with the yarn clamping sleeve. The yarn clamping anvil roller is arranged on the machine frame. The yarn clamping mechanism overcomes the disadvantages that a traditional yarn clamping mechanism is bad in reliability and can only be used under a low-speed condition, and long weft easily appears due to the fact that an electronic weft accumulator is utilized to release the weft at a certain length, waste is caused, and certain beneficial effects are achieved.

Description

A kind of yarn clamping mechanism

Technical field

The utility model relates to field of textiles, especially a kind of yarn clamping mechanism.

Background technology

Commercially available type does not have this yarn clamping mechanism at present, put latitude by the electronic weft storage device fixed length, the air drawing yarn, yarn is smoothed out with the fingers directly, because the stream pressure size can not be in full accord, more or less some fluctuation, so cause weft yarn different in size, occur long latitude especially easily and cause waste, the little air-jet loom of other type uses F1515 handwoven cloth machine torsion spring to add cam gear and realizes the parallel yarn clamping mechanism, reliability is too poor, can only use under the low speed situation, general speed-adaptive can not satisfy instructions for use at 180-190 rev/min fully at existing type 450-500 rev/min.

The utility model content

The utility model is intended to address the above problem, a kind of yarn clamping mechanism is provided, it has overcome, and traditional yarn clamping mechanism reliability is too poor can only be used and adopt the electronic weft storage device fixed length to put latitude under the low speed situation to occur long latitude easily and cause drawbacks such as waste, and its technical scheme that adopts is as follows:

A kind of yarn clamping mechanism comprises main motor, cam, big rocking bar, big rocking bar pillar, pull bar, spring support plate, back-moving spring, back-up ring, first holder, rotating shaft, shaft seating, second holder, yarn clipping cover and yarn clipping anvil roller;

Described main motor is installed on that its turning cylinder is connected with cam on the frame;

Described big rocking bar can rotate around big rocking bar pillar under the driving of cam, and an end of one end and pull bar is rotationally connected;

Described spring support plate is rotationally connected with on the frame and is set on the pull bar and is slidingly connected with pull bar;

Described back-up ring is located on the pull bar;

Described back-moving spring is between spring support plate and back-up ring;

One end of described first holder and an end of pull bar are rotationally connected, and the other end and rotating shaft are affixed;

Described rotating shaft is threaded onto in the shaft seating and with shaft seating and is rotationally connected, described shaft seating and frame Joint,

One end and the rotating shaft of described second holder are affixed, and the other end is connected with the yarn clipping cover;

Described yarn clipping anvil roller is static roller, is installed on the frame.

On the technique scheme basis, this yarn clamping mechanism also comprises trundle, and described trundle is rotationally connected with on the end of big rocking bar and with the rolling surface of cam and contacts.

On the technique scheme basis, described big rocking bar pillar is connected with frame by connector.

The utlity model has following advantage: stable performance can be used under high-speed case, and clamping is firm, and is reliable; Can guarantee every one thread length unanimity, satisfy the braiding requirement, percent defective is low to be can be the manufacturer and saves cost, by adjustment cam, can prolong or shorten the clamping yarn time, is convenient to shear yarn, regulates fast.
