Description

Yarn hairiness reduction device

technical field

The invention belongs to a special textile mechanical device, in particular to a novel yarn hairiness reducing device.

Background technique

For the production of smooth fabrics, it is very important to reduce yarn hairiness. Too much yarn hairiness not only affects the subsequent procedures, but also affects the appearance of the fabric. The existing yarn hairiness reduction devices mainly include: (1) the publication number is CN1392298A, Hairiness reduction device with friction wrapping tube; (2) Publication No. CN1388281A, winding yarn hairiness reduction device with wiper; (3) Authorized announcement number CN2576733Y, collection yarn for reducing hairiness (4) A new type of compact spinning device that reduces hairiness. To sum up, most of the above-mentioned devices face disadvantages such as high manufacturing cost, low work efficiency, and difficult yarn adjustment. In addition, the Swiss company Rieter has researched and developed a new spinning process, Combospin, which is unique in that a fiber clustering mechanism is added in the middle of the drafting and yarn twisting areas, in which the original front bottom roller is replaced by a perforated roller. The drum is equipped with a fixed vacuum system. After the fiber is output from the bell mouth of the double-apron and three-roller drafting system, it is firmly adsorbed on the surface of the porous drum and moves at the surface speed of the drum. In the middle area between the top rollers, a special chute is installed inside the drum to allow airflow to pass through, and under the combined action of the angle of the chute and the airflow, the fibers attached to the surface of the drum are laterally condensed, thereby reducing yarn hairiness. This device also has the disadvantages of high manufacturing cost, low efficiency and difficult yarn adjustment.

Detailed ways

The present invention will be further described below by way of examples, but the present invention is not limited thereto.

The device adopts the general mechanical design method, and it has a built-in air jet device; the blade is driven by a pulley, and the tension of the belt is adjustable; the angle of the whole device is adjustable, and it can be adapted to various spinning frames. It mainly includes a box plate 1, a support 5, a rotary blade group, an air injection device, a transmission device, a yarn adjustment device, the transmission device is connected with the rotary blade group, and the air injection device is arranged on one side of the rotary blade group and connected with the support. , the yarn adjusting device makes the passing yarn pass through one side of the blade set.

As shown in Fig. 1 and Fig. 2, the rotary blade group is made up of two flat circular single-edged blades 9, and the blades of the two blades are opposite. The blade and the pulley 2 of the transmission device are fixed on the bracket 3 through bearings, the blade is fixed on the transmission shaft 4 by two washers 8 through clamping nuts, the transmission shaft is placed on the shaft sleeve 10, and the shaft sleeve is fixed on the bracket through nuts , There is an interference fit between the transmission shaft and the pulley. As shown in Figure 5, the transmission mode of the pulley, the centers of the upper pulley 22 and the lower pulley 19 connected to the transmission shaft are on the same vertical line, the center of the drive pulley 21 is basically at the same level as the center of the lower pulley, and the adjustment wheel 20 The center deviates from the straight line where the two belt pulleys are located, away from and lower than the drive pulley. The belt shuttles between the two driven wheels in an S shape, and then connects with the adjustment wheel.
