Description

Devices are known for mixing roll mixtures consisting of a bed and a group of mixing knives mounted on it with a curved surface.

In the teelable device for intensifying the process of kneading, in the construction, transporting and pressure rollers located in the lower part of the bed are connected with a pair of cropping knives and moving the rolled mixture along the roller.

FIG. 1 shows a diagram of the proposed device; in fig. 2 is a section along the line A-A in FIG. one.

The mixing device is a complex of rollers of knives mounted on rollers with necessary auxiliary devices. The main components of the mixing device are: mixing knives, mounted 1 on the cross beam 2, undercut knives 3, transporting rollers 4, 5 and pressure roller 6.

The knife is fixed by the clamping screw 7 in the housing of the holder 8. The knife holder 8 has the shape of a wedge with inclined planes, due to which the trimmed mixture of the mixture is detached from the surface of the roll. In one case with a knife, a hinge 9 is mounted, carrying a guiding wing. The angle of capture of the wing is adjusted by the screw 10. The sporting rollers 4 and 5 and the pressure roller 6 are mounted on rolling bearings and can be rotated at any angle relative to the plane of the tape to be cut.

The rubber mixture, the incursion of the knife-and /, is cut into separate strips, which with the help of wings 11 are wrapped in rolls and fed into the gap between the rollers. Below, knob roller, set the cutting knives, which cut the ribbon of the desired width from the total

L-148502-2-2 masses of the mixture. This tape is fed to the rollers 4, then through the rollers 5 and 6 continuously fed to the roller roll.

At the end of the mixing cycle, the tape is cut off and loaded onto the conveyor 12. When the mixture on the roll remains a little (/ from the length of the roll), the next charge of the mixture is loaded, which envelops the roll due to the left margin. The stock is removed, and the belt is cut from the conveyor belt and reloaded onto the rollers and roller coaters. The cycle is repeated.

Item and h

A device for mixing rolled mixtures, consisting of a frame and a group of mixing knives mounted on it with a curved surface, characterized in that the transport and pressure rollers located in the lower part of the frame are used to intensify the process of plasticization moving movement of rolled seam along the roll.
