Description

one

The invention relates to the textile industry, namely to devices for feeding fiber processing machines, in particular carding machines, with a fibrous material.

The purpose of the invention is to improve the quality of the product by providing additional mixing of individual portions of fibers.

Figure 1 shows the bunker, a general view; figure 2 is a view of And figure 1; Fig. 3 shows a dual hopper for processing two types of fibers, option.

The bunker includes a housing in the form of a shaft 1, a paddle shaft 2, a chute 3. The shaft 2 is located inside the cylindrical chute 3 and coaxially with it. In the lower part of it along the generatrix there is an outlet. Cylindrical, the forehead is mounted on the shoe 4, in which there is the same opening. The shoe is fixedly mounted to the shaft 1, below the shoe is the drive shaft 5.

A restrictive bar 6 is installed inside the shaft above the blade shaft, necessary to eliminate excess fiber if they are formed in: the blade shaft sector 2. In the upper part of the shaft 1, valve 7 is installed to maintain a predetermined air pressure. To remove dust between the bapmac and the semi-cylindrical chute, there are suction units 8 mounted on the wall of the shaft 1.

The bunker works in the following manner.

The fiber from the previous machine is fed into the bunker along the arrow as shown by the Kot-

but in figure 2. It is possible to feed the fiber from the top along the dotted arrow (figure 1). Once in the housing 1 (figure 1), the fiber loads the sectors of the rotating blade shaft 2. The blades of this shaft push the fiber in the direction of the arrow (figure 1).

with oscillatory movement around the same horizontal axis around which the blade shaft 2 rotates. At some points in time, the hole in the cylindrical chute 3 is aligned with the same hole in the shoe 4. At this moment, the fiber is loaded into the storage shaft 5. By adjusting the rotational speed of the blade shaft and the law of oscillation of the cylindrical trough, such a situation is achieved that the fiber portions from the blade shaft sectors enter the storage shaft 5 of the bunker not successively one after another, but through a certain number of sectors. This contributes to the mixing of the fiber, which means higher quality of the carding tape. .

The law of oscillation is set by a control system (not shown).

Dust accumulating in the gap between the shoe and the cylindrical chute is removed through the suction 8.

The bunker can be used to power textile machines with a heterogeneous composition of a fibrous material from natural and chemical fibers. In this case, dual 40

a bunker (fig. 3), in each section of which one type of fiber enters.

The use of a cyclic, metered supply of fibrous material in the hopper permits an increase in the quality of the combing tape by mixing the individual portions of the fiber.
