Abstract

SUMMARY OF THE INVENTION: a tape forming unit of a roller carding machine comprises exhaust cylinders, pressure rollers equipped with holders, belt forming funnels, tape guides, an exhaust head. According to the invention, between the exhaust cylinder and the exhaust head there is a belt conveyor mounted along the exhaust cylinders under the belt guides. Each ribbon forming funnel is made over the entire width of the pressure roller and rests on its holders. The latter are installed on the side of the tape drive. 3 ill.

Description

The invention relates to the textile industry and relates to roll carding machines for processing bast fibers.

The purpose of the invention is to improve performance while increasing productivity.

In Fig. 1 is a schematic diagram of a roller carding machine; in FIG. 2 - tape-forming unit of the roller carding machine; in FIG. 3 is a plan view of the assembly.

The roller combing machine comprises a roll feed mechanism 1 installed along the process and kinematically connected to each other. . feeding conveyor 2, feeding 3 and zero cleaning 4 rollers, two main drums 5 and 6 interacting with each other, scratching 7 and cleaning 8 rollers, removable drums 9, whipping ridges 10 and a belt forming unit of the machine, including exhaust cylinders 11 with pressure rollers 12 equipped with de

clamps 13, belt forming holes 14, belt guides 15 of the lower exhaust cylinder 11, a conveyor 16 and an exhaust head consisting of feed cylinders 17, a comb mechanism 18, an exhaust mechanism 19, an upper conveyor 20, a lower conveyor 21, an automatic machine 22 changing the accumulated pelvis 23, the drawn-out head is equipped with an auto-regulator 24 of the linear density of the tape, in which one of the supply cylinders 17 serves as a sensor of the linear density of the tape entering the exhaust head.

In carding machines for fine caring of bast fibers, as a rule, there are two removable drums, and consequently, two release mechanisms - upper and lower. The holders 13. of the pressure rollers 12 and the ribbon couplers 15 are mounted and secured to the links 25 of the frames 26, 27 of the carding frame. Under the removable drums are pallets 28.

Each ribbon forming funnel 14 is made over the entire width of the pressure roller 12 and is located on its holders 13.

The machine operates as follows.

The fibrous stream from the roll tapes with the help of mechanisms 1, 2 enters the carding unit 3-4-5-6-7-8-9, where the fibers are combed, mixed, the fiber stream is cleaned from fires and indirect impurities and the fiber is thinned flow.

The combed fiber from the removable drums 9 is removed in the form of several streams (according to the number of pressure rollers) by the combed ridges 10. Each of the fiber flows passes through a belt-forming funnel 14, is compressed by a pressure roller 12 and, thus, a tape is formed. The upper outlet tapes are duplicated with the corresponding lower outlet tapes, passing through the tape forming funnels 14 of the lower exhaust mechanism.

Further, the tapes from under the pressure rollers 12 of the lower outlet are fed to belt conveyors 15, by means of which the tapes change the direction of movement by 90 °. Then the belts are conveyed by the conveyor 16 to the exhaust head, passed through an exhaust device consisting of feed cylinders 17, a comb mechanism 18 and an exhaust mechanism 19, where the fiber flow is drawn and the fibers are parallelized in the tape, B the process of drawing the fiber flow automatically aligns the linear density of the tape with the autoregulator 24,

The tape with the help of the upper 20 and the lower 21 tape layers is laid: in the basin 23. The number of accumulated tape in the basin is set by a special device (not shown in the drawing), on command of which, the machine 22 for changing the accumulated basin 23 is activated.

The tape forming unit is also applicable to roller carding machines with one outlet unit (one removable drum).

Each ribbon-forming funnel 14 is made over the entire width of the pressure roller 12 and is located on its holders 13 mounted on the side of the tape guide, i.e. from the side of the tape discharge from under the pressure roller, which ensures unhindered advancement of the carded fiber from the removable drum 9 to the exhaust cylinder 11 and makes it possible to reduce to zero the breakage of the fiber flows during the formation of the tapes.

The belt conveyor 16, located between the exhaust mechanism and the exhaust head along the exhaust cylinder under the belt guides 15, provides for the forced transportation of belts from the machine’s exhaust mechanism to the exhaust head, which completely eliminates the breakage of the tapes and uncontrolled stretching of the tapes in this area, allowing it increases the speed of formation of a strip of carded fiber, and therefore

machine performance.
