Technical Field

The invention relates to a main port yarn feeding device, in particular to a main port yarn feeding device based on front and back independent adjustment of a main shuttle.

Background

In the current market, the types and varieties of hosiery machines are relatively more, and the hosiery machines mainly fall into two categories, namely an inlet hosiery machine and a domestic hosiery machine. The main port yarn feeding device adopted by each machine type is in various shapes and colors.

The import hosiery machine adopts a high-precision processing and positioning mode to control the optimal matching position of a main port yarn feeding device and a knitting needle to weave fabrics, and several shuttles are provided with a front-back adjusting function to adjust the front-back position of the shuttles when special fabrics are woven. The method has high control precision, high stability of the woven fabric and low defective rate. The defects that when special socks are produced, the positions of all the shuttles cannot be adjusted, so that individual socks cannot be used or the defective rate is high, so that the machine cannot normally run, and the limitation is large; and later maintenance cost is higher, and damaged parts can only rely on original factory import accessories, and the purchase cycle is long and the price is expensive.

Most domestic hosiery machines adopt a lever swing adjusting mode to control the front and rear positions of the shuttles, and the front and rear positions of each shuttle can be independently adjusted, so that the optimal position of the main port yarn feeding device matched with a knitting needle for fabric knitting is achieved, but the lever swing adjusting mode needs to occupy a large space to realize, the lever distance of the shuttles is relatively long, the left and right swing gap of the shuttles is large, and the defective rate is greatly improved due to unstable yarn feeding. If the left-right swinging gap of the shuttle is adjusted to be small, the shuttle is blocked during working, and defective products are caused. Relatively speaking, the lever swing adjustment mode is adopted, the later operation requirement is quite high, if the operation is not proper, the defective rate is increased, and great loss is caused.

Disclosure of Invention

A main port yarn feeding device based on independent front and back adjustment of a main shuttle comprises a main shuttle frame, wherein more than 2 main shuttles are arranged on the main shuttle frame, and at least one main shuttle is provided with an adjusting device which is matched with the front and back positions as well as the up and down positions; the adjusting device comprises a front adjusting device, a rear adjusting device and an up-down adjusting device; the front-rear adjusting device includes: the regulating sheet is shaped in such a way that a limiting sheet and a connecting sheet are respectively arranged at the upper end and the lower end of the front end, a front-back regulating sheet is arranged at the rear end, the connecting sheet is connected with the main shuttle, the regulating sheet is arranged on a main shuttle regulating seat, and a front-back regulating screw matched with the front-back regulating sheet is arranged on the main shuttle regulating seat; the up-and-down adjusting device comprises: and the limiting jackscrew seat is arranged on the main shuttle frame, a limiting jackscrew is arranged on the limiting jackscrew seat, and the limiting jackscrew is matched with the main shuttle. The main port yarn feeding device adopts the structure of the adjusting sheet to match with the front and back adjusting device and the up and down adjusting device matched with the main shuttle, so that the up and down position and the front and back position of the main shuttle can be adjusted, and the precision of the equipment is greatly improved.

The regulating blade at least comprises a first regulating blade and a second regulating blade which are of two different structures, the first regulating blade is in a shape that a limiting blade is arranged on the upper side of the front end, a connecting blade is arranged on the lower side of the first regulating blade, a front and rear regulating blade is arranged on the rear end of the first regulating blade, a limiting blade is arranged on the lower side of the front end of the second regulating blade, a connecting blade is arranged on the upper side of the second regulating blade, and a front and rear regulating blade is. The difference of the driving positions between the main shuttles is realized through two different adjusting piece structures of the first adjusting piece and the second adjusting piece, and the adjustability and the stability of the gap between the main shuttles in the left-right swinging mode are realized.

The main shuttle adjusting seat is provided with a mounting groove for mounting the front and rear adjusting pieces, the mounting groove is provided with a pressing piece for pressing the adjusting pieces, the front and rear sides of the mounting groove are respectively provided with a front adjusting screw and a rear adjusting screw, and the front and rear positions of the front and rear adjusting pieces, namely the front and rear positions of the main shuttle, are adjusted by rotating the front adjusting screw or the rear adjusting screw.

The main shuttle adjusting seat is lower than the limiting thread jacking seat relatively, the front and back position adjustment of the main shuttle is in a low position, the height adjustment is in a high position, and the overall adjusting performance is more stable.

More than 2 main shuttles all cooperate and be provided with adjusting device, realize that all main shuttles can all adjust the position relation from top to bottom, front and back, further improve knitting effect.

The end part of the connecting piece is of a circular structure and is matched with a round hole in the main shuttle, so that the main shuttle can rotate up and down and can adjust the position back and forth under the driving of the connecting piece.

The invention adopts the structure of the adjusting sheet to match with the front-back adjusting device and the up-down adjusting device matched with the main shuttle, realizes the adjustment of the up-down position and the front-back position of the main shuttle, greatly improves the knitting precision, reduces the defective rate and is convenient to maintain.
