Description

Loop wheel device for quiding threads

The utility model relates to a kind of yarn-feeding device of Knitting Machinery.

Chassis is a big series products in the knitting weft-knitted equipment, and it is because of having the production efficiency height, and characteristics such as the operation cost is low are the knitting industry extensive use, along with the development of novel large circle machine, how to improve the quality of chassis fabric, are the problems that users pay close attention to.The application of chassis Thread-feeding device on chassis is the key point that solves quality problems, it has the certain length of yarn of control, the little characteristics of yarn tension fluctuation, and has a broken yarn self-stop function, therefore change the uncontrollable disadvantage of chassis fabric threads circular structure in the past after chassis uses this device, the fabric of being produced has the loop construction uniformity, the very protruding remarkable advantage clearly of woven design is improved the chassis fabric quality completely, weaves high-grade fabric for chassis and has created advantage.But the reasons in structure of existing chassis Thread-feeding device, yarn is input as from top to bottom to be carried, so both changed the operating habit of shelves turners, again to the maintenance worker repair, spinner's cropping brings many inconvenience, because of chassis when the braiding, the trend of yarn is served as reasons down and is upwards carried, the cropping spooler is located at the chassis top, deposits the Thread-feeding device that draws formula if adopt on this, certainly will change the defeated yarn of chassis, plaiting apparatus causes very burden.

The purpose of this utility model is exactly in order to adapt to the traditional operating habit of loom workman, designs a kind of handled easily, rationally advances the chassis Thread-feeding device of yarn.

Finishing task of the present utility model is the creel of fixing on housing with guide porcelain circle that advances, yarn clearer, yarn gripper, cross the yarn hook, self-stop device, tension rail is hinged on the self-stop device, the major axis of power transfer part is bearing in the housing oiliness bearing hole, major axis tightens the set drive, yarn storage wheel, cool off the fan guard and the fan of usefulness in addition, for the positive feeding speed that guarantees yarn consistent with the braiding speed of loom, reduce the fluctuation of yarn, guarantee to stablize tension force, guarantee the constant yarn that send, the input of yarn is through many links, in order rationally to advance yarn, handled easily, therefore will advance creel and change the oblique setting of underlying top-guiding type into, with yarn storage wheel horizontal sextant angle α be 105 °～115 °, and set out creel at output, this goes out creel and is fixed on the housing, with yarn storage wheel horizontal sextant angle β be 65 °～75 °.

Chassis Thread-feeding device after improving, adopt the yarn trend of underlying top-guiding type, just needn't change defeated yarn, the plaiting apparatus of chassis, the traditional operation custom that keeps the loom workman, made things convenient for operation, defeated yarn is reasonable, and it is as the auxiliary facility of the defeated yarn of chassis, be to guarantee the constant important means of sending yarn, weave out high-grade fabric for chassis and created advantage.

Description of drawings.

Fig. 1 is an overall structure schematic diagram of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

By above-mentioned accompanying drawing embodiment, be further elaborated.

The housing (6) of chassis Thread-feeding device (seeing Fig. 1-2) is the main body part in addition of defeated yarn system of supporting and power transfer part, is again the connection part in addition that articulates chassis, articulates the back by screw (7) tightening.Fix creel (2), yarn clearer (18), yarn gripper (17) on the housing (6), crossing yarn hook (12), self-stop device (8).The creel (2) that advances of shape of cranking arm is the oblique setting of a top-guiding type, it and yarn storage wheel (14) horizontal sextant angle α=and 110 °, advance creel and be provided with 3 guide porcelain circles (1), (3), (16).Two tension rails (13), (15) are hinged on the self-stop device (8), and the contact chip by tension rail (13), (15) control is housed in the self-stop device (8), can reach broken string by it and make the Main Engine Cut-Off purpose.That is fixing the shape of cranking arm on the housing (6) of yarn output goes out creel (10), is equipped with 2 on it and yarn storage wheel (14) horizontal sextant angle β=70 ° frame and pays yarn porcelain circle (9), (11).

There is a major axis (21) that is bearing in housing (6) oiliness bearing (20) hole power transfer part, is fixing fan guard (4), fan (19), drive (5), yarn storage wheel (14), power on the major axis and is driving drive (5) by the driving belt input and drive yarn storage wheel (14) running through major axis (21).

Yarn input is penetrated-porcelain circle (3)-yarn clearer (18)-yarn gripper (17)-porcelain circle (16)-tension rail (15)-yarn storage wheel (14) coiling 10-15 circle-tension rail (13)-mistakes yarn hook (12)-yarn porcelain circle (11), (9)-feed the loom woven extent by the porcelain eye of guide porcelain circle (1), and it is consistent that the input that has guaranteed yarn and loom weave speed.

Tension rail (13), (15) rely on the yarn supporting, and mistake is opened in case disconnect when yarn, and tension rail falls under the deadweight effect, and the contact chip in the bump self-stop device (8) impels Main Engine Cut-Off.

Claims (1)

1, a kind of chassis Thread-feeding device, one housing (6) and the holding screw (7) that articulates with the main frame steel loop arranged, fixing on the housing (6) and having advancing creel (2), yarn clearer (18), yarn gripper (17), crossing yarn hook (12), self-stop device (8) of guide porcelain circle (1), (3), (16), tension rail (13), (15) are hinged on the self-stop device (8), fan guard (4), fan (19), drive (5), yarn storage wheel (14) are fastened on the major axis (21), and major axis (21) is bearing in housing (6) oiliness bearing (20) hole, it is characterized in that:

A. to advance the yarn mode be the oblique setting of top-guiding type to yarn, and advancing creel (2) is 105 °～115 ° with yarn storage wheel (14) horizontal sextant angle α,

What b. the yarn output was provided with oblique setting goes out creel (10), and it is fixed on the housing (6), and going out creel (10) is 65 °～75 ° with yarn storage wheel (14) horizontal sextant angle β.
