Description

Roving frame

Technical Field

The utility model relates to a fly frame technical field especially relates to a fly frame.

Background

A roving frame is a spinning machine for making a fiber sliver into roving. The roving frame mainly plays a role in drafting and twisting, and winds the roving into a certain package to meet the processing requirements of the spinning frame. The roving frame is divided into a flyer roving frame and a twisting roving frame in the form of a twisting mechanism. The flyer roving frame rotates by means of flyer to continuously apply twist to the sliver so as to produce twisted roving. The twist roving frame clamps and twists the yarn by a pair of twist leather plates, and forms a false twist with alternate forward and reverse directions on the yarn to produce untwisted roving.

At present, the development of roving frames is mainly focused on high speed, large packages and automation. The roving frame is considered as a transition process between drawing and spinning, and the main function is to reduce the drafting burden of the spinning and simultaneously change the package form to improve the production efficiency of the spinning frame. And the function of the roving frame in product development is rarely taken into consideration.

The sectional color yarn is one of fancy yarns and has unique style characteristics. The sectional color yarns can be combined according to the design requirement, and can adopt multi-fiber spinning on the cross section of the yarns or multi-color fiber spinning in sections in the longitudinal direction. At present, the segment color yarn is produced by adopting a spun yarn position mixing method, namely, the segment color yarn can be produced by properly modifying a spinning machine, but the method is easy to cause the situation that the suitable spinning fiber is limited. Therefore, a roving frame is proposed to solve the above problems.

SUMMERY OF THE UTILITY MODEL

According to a further technical scheme, a cotton sliver collector is further arranged between the first roller and the second roller.

According to the further technical scheme, the upper rubber ring and the lower rubber ring are both arranged at one end of the third roller, which is small in diameter.

Compared with the prior art, the utility model, have following apparent advantage:

1. this kind of fly frame adopts four roller transmissions, and the last roller of third roller adopts the last lower rubber ring that ladder roller design third roller to divide into two parts according to the working width direction, respectively account for one half, and partly still installs in the primary importance by the third roller transmission, and long rubber ring has been designed to another part, is in the same place with the fourth roller, by fourth roller transmission rubber ring, is favorable to two kinds of silver layering transportation, feeding draft mechanism, has increased the kind that suits to spin fibre, and is convenient for produce the various yarns of linear density section such as.

2. The cotton sliver collector is arranged between the first roller and the second roller, which is favorable for gathering two fiber strips together to form the fiber strips which are connected end to end, and then the fiber strips are twisted and wound to form roving, thereby improving the processing quality of segment color yarns and avoiding the phenomenon that the intermittently fed cotton sliver is sucked away; meanwhile, the third roller and the fourth roller are driven by a servo motor, the drafting transmission of the roving frame is greatly simplified, the exchange of drafting gears is omitted, the length and the thickness of each section of cotton sliver are accurately controlled, and the technological requirements of various sections of colored roving production are met.

3. The utility model has the advantages of simple structure, convenient to use, the practicality is strong, is fit for using widely.
