SU66460A1 - Device for feeding carding machine - Google Patents

Description

The proposed device is intended for feeding the carding machine with a uniform layer of fibrous material, for example, from a bunker, and is characterized by using a perforated shaft with a saw headset installed directly from the alignment roller, on the other hand, from the alignment roller. a roller conveying the fibrous material to the drum.

In the drawing fng. 1 illustrates the principle of operation of the device, FIG. 2 schematically depicts a side view of an exemplary embodiment of the device.

If there are two carded surfaces and the opposite arrangement of their needles, the position of the fiber between these surfaces is not definite: the fiber can pass from the bearing surface or remain: on it.

If the body of the carrier roller / (Fig. I) is perforated and the air is sucked in, then another roller 2 will remove only those that are higher than the ends of the roller needles /, i.e. which are outside the field of action of the bearing needles. In such a case, the removal will take place under the comb, and on the roller 1 there will remain an even layer of loosened fiber, which can then be transferred for further processing.

It should be made like a roller ./ in the form of a perforated drum with perforated grooves for an 11-strap, only more rare than that used on the receiving drum of a carding machine.

The device for feeding the carding machine is shown on the fng. 2

The fiber with npneiMHoro drum 3, which is already quite loosened, is removed by the air pull of the high speed mesh drum 4 and is thrown onto a perforated roller 1 having a lower spin speed of 1.

The fiber covers the surface of the roller 1 in a somewhat leveled layer under the action of air and pi, but the main and final alignment produces a counter: rotating leveling roller 2.

From the roller 2, the fiber is returned to the take-up drum 5. From the roller / fiber is removed by the roller 5 (or brush) and transferred to the drum 6.

Thick layer of fiber on roller 7

depends on the height of his saw headset and the number of revolutions.
