Description

Yarn twisting mechanism of circular weft knitting machine

Technical Field

The utility model relates to a knitting machine field of circular weft especially relates to a knitting machine of circular weft twists with fingers yarn mechanism.

Background

The direct twisting process is evolved from the two-for-one twisting process, and since the eighties, mechanical structures and processes based on the direct twisting technology are developed and perfected due to the improvement of electronic control technology and manufacturing technology. In recent years, several types of cord thread straight twisters have come into the domestic market, such as a CC type straight twister by alma company in germany, a G48T type straight twister by RPR in italy, and an AC10 type straight twister by bamag company in germany. The straight twisting process is to directly bond two single-strand strands without twisting into a cord in a cable twisting mode.

In recent years, the knitting technology and equipment manufacturing level in China are rapidly developed, the conventional circular knitting machine can replace imported equipment, but part of machine types mainly adopt simulation, the core technology is still few, and the reliability and the stability of the circular knitting machine are still to be improved.

Moreover, the existing direct twisting machine and the existing circular weft machine in the market exist separately, the direct twisting machine finishes the direct twisting process of the cord thread, and simultaneously, the twisted silk thread is wound into a bobbin. The cheese is sent to a creel of a circular weft knitting machine for knitting by the circular weft knitting machine, which can only complete knitting work of knitwear. The yarn to the cord fabric finished product needs two main processes of straight twisting and weaving and a series of related auxiliary works, such as bobbin unloading, bobbin loading and bobbin loading, and a bobbin creel is used by a circular weft knitting machine, the auxiliary works inevitably consume a lot of manpower and material resources, consume a lot of time and space, belong to high-intensity labor work, and greatly consume the physical ability and spirit of operators. Moreover, frequent bobbin unloading is avoided, and the frequency of stopping and starting the machine is increased. This inevitably leads to a reduction in the production efficiency of the cord fabric and difficulty in ensuring the product quality. And the direct twisting machine and the circular weft knitting machine are separated, so that the occupied space is inevitably increased, the production space of an enterprise is greatly wasted, and moreover, two working procedures are separately operated, two operating personnel are required to be equipped, and the labor cost is inevitably greatly increased.

SUMMERY OF THE UTILITY MODEL

The technical problem that this practicality will be solved provides a circular weft knitting machine yarn twisting mechanism that occupation space is little, simple structure, job stabilization, work efficiency height, cost of labor are few.

In order to achieve the purpose, the technical scheme of the utility model is as follows: the yarn twisting mechanism of the circular weft knitting machine comprises a support frame arranged on the circular weft knitting machine, spindles arranged on the support frame, more than two yarn inserting rods arranged on the support frame and a servo motor used for driving the spindles to rotate, wherein a yarn guiding ring is further arranged on the support frame, and yarn guiding rods corresponding to the yarn twisting mechanisms are arranged on the yarn guiding ring.

Preferably, the support frame is provided with a spindle seat plate, the spindles are arranged on the spindle seat plate, and two adjacent spindles are separated by a partition plate.

Preferably, the spindle seat plate is arranged on the support frame in a height-adjustable manner through a plurality of bolts.

Preferably, the spindle comprises a hollow rod rotatably arranged on the support frame, a yarn twisting disc arranged on the hollow rod, and a spindle pot arranged on the hollow rod, wherein an inner yarn winding reel is arranged in the spindle pot, a tension balancer is arranged in the spindle pot, a line passing porcelain ring is arranged on the spindle pot, and the servo motor is in transmission connection with the hollow rod.

The technical scheme has the following beneficial effects:

1. the twisting circular weft knitting machine has the advantages that due to the fact that a plurality of structures and functions are integrated and optimized, the machine structure is greatly simplified, the occupied space of a machine body is greatly reduced, the operation space is reduced from two traditional operations to one operation, and therefore the space is greatly saved by the integrated twisting circular weft knitting machine;

2. after the twisting process and the weaving process are integrated, the structure and the system are reasonably integrated and optimized, and the design and manufacturing cost is greatly reduced;

3. in the traditional process, operating personnel are required to be respectively configured for twisting and knitting, and only one operating personnel is required to be configured for the integrated twisted yarn circular weft knitting machine, so that the labor cost is greatly reduced;

4. the two processes are carried out separately, the intermediate link inevitably consumes much time, and a plurality of intermediate auxiliary links are saved after integration, so that the operation time is greatly shortened, and the production efficiency is greatly improved;

5. the traditional twisting process and the weaving process are separately operated, a series of intermediate turnover links such as disassembly and movement increase the labor intensity of operators, after integration, a series of auxiliary work such as disassembly, assembly, machine adjustment and the like is avoided, the labor intensity of the operators is greatly reduced, the mental state of the operators is optimized, and a foundation is provided for improving the production efficiency and the weaving quality;

6. as is known well, frequent bobbin unloading, bobbin loading and frequent machine debugging are inevitably difficult to ensure a stable production condition, and the efficiency and the quality of fabrics cannot be guaranteed. After the integration, the twisting and the weaving are synchronously and coordinately completed on one machine, so that an intermediate auxiliary link is omitted, a stable production condition is obtained, and the efficiency and the quality of the fabric can be guaranteed.
