Color change head control mechanism improvement

This creation is about the improvement of a color change head control mechanism, especially a control mechanism for a special color change head of a circular knitting machine.

In the conventional circular knitting machine, if the fabric needs to be woven with different color patterns, a color change head is added to the yarn feeding opening of the knitting machine, and the color changing head will be timely during the knitting process. The colored yarn is brought to the yarn feeding port to allow the knitting needle to be crocheted to weave the colored yarn together, so that the woven fabric has a different color pattern effect.

The conventional color changing head is installed on the knitting machine, and under the control of the pushing track of the knitting machine and the needle selector, the color selecting plate and the pushing plate are sequentially driven to operate, and the knitting needle is made of colored yarn. The yarn feeding action allows the woven fabric to have a different color pattern effect. However, the color selection plate of the color change head control mechanism is an integrally formed double curved arm design, so that the precision control of the matching between the color selection plate and the push plate is difficult, and the color selection plate and the push plate are made. The pressing is more difficult, and the color selection plate and the push plate are also difficult to reset upwards. Therefore, the color selection plate and the push plate often have troubles. If there is a slight error between the two, It is easy to cause malfunctions, which in turn leads to errors in the color switching of the yarns, causing serious losses to the operators. So how do you solve it? The deficiencies and shortcomings of the above-mentioned conventional technologies are the subject of the desire of those involved in this industry.

The main purpose and function of the creation is that the color selection board of the color change head control mechanism mainly adopts a two-piece pivot connection design, and the color selection board is divided into the first link and the second link which are pivotally linked to each other, so that the color selection is performed. The pressing action under the plate and the push plate is relatively labor-saving, and it is easier to reset upwards, and the malfunction can be avoided. .

In order to achieve the above, the present invention provides a modification of the color change head control mechanism, comprising: a body, which is provided with a positioning rod; a plurality of color selection plates, which are disposed at intervals inside the body, the color selection boards Each of the first link ends is pivotally disposed on the body, and the front ends of the first links are respectively disposed at the upper ends of the second links, and the second links are adjacent to each other. The upper end and the lower end respectively form an open guiding portion and a front facing portion, so that the guiding portion contacts the positioning rod; and a plurality of pushing plates are arranged to move up and down inside the body, each of which is disposed inside the body The pusher plate is disposed in front of each of the color selection plates, and the top crotch portion of the second link of each color selection plate is abutted against the push plate.

In a preferred embodiment, the rear end of the first link is pivotally mounted to the body. Moreover, the upper end of the second link is pivotally mounted to the first link by a pivot pin.

In a preferred embodiment, the inner edge of the guiding portion of the second connecting rod is provided with a positioning slot and a guiding slot. The guiding slot is located above the positioning slot, and each of the first connecting rods is provided with an elastic element, each elastic The element abuts against the lower edge of the first link such that the positioning rod is placed in the positioning groove of the guiding portion of the second link toward the front gear.
