SU24283A1 - Adaptation to carding machines for automatic removal of cotton from a canvas drum - Google Patents

Description

An adaptation to carding drums is proposed for automatically removing cotton from a canvas drum by means of a slider brought into a reciprocating motion by a crank mechanism.

The device is shown in the schematic drawing.,

In the carding machine, the finally combed fiber from the last work roller 28 is transmitted by the courier 29 to the carding drum 25, which carries it to the runner 32, covered with the headset jogger, which, due to the speed difference between the runner and the carding drum, lifts the fiber to the teeth of the drum 25, making it possible for the fiber to be freely grasped by the reamers 34 and 35. The latter, having a card headset, are inclined against the teeth of the punching drum and rotate in the direction opposite to the rotation. carding baraba a 25, -free pnnimayu1T raise

"4 crescent combs 36 and 37, which remove the fibers in the form of a wadding wound on canvas with a canvas drum 38, from where the canvas is automatically removed using the following device.

A gear 42 is mounted on the axis of the canvas drum, engaging with the gear

a wheel 43, which makes a revolution beyond five revolutions of gear wheel 42. A crank 44 is mounted on the axis of the toothed wheel 43, which causes the slider 46 to be moved by the connecting rod 45, which moves along the guide 53 and carries the roller 47 on the rod. moving to the right, roller 48, attached to end 49, presses it and causes roller 48 to move to the right as well, until roller 48 comes out of contact with it. The roller 48 in its movement turns the lever 49 and the axis 52 rigidly attached to it by a small angle, against the direction of the movement of the hour hand. On axis 52, a lever 50 with a comb is also rigidly fastened to it. When the axis 52 is rotated, this lever with a comb is rotated at the same angle counterclockwise and, almost touching the canvas drum 38, with a short movement quickly removes cotton from it and quickly folds back with a spiral spring 51, as the roller 48 is in contact With the roller 47 is a very short time, and the spring 51 is designed to keep the ridge 50 at a distance of 80 mm from the drum 38. When the slide 46 is moving back (to the left), the roller 47 presses the roller 48 on the reverse side and pulls the comb 50 away from the drum even more 38; slider 46, moving to the left, removes roller 47 from contact, and then ridge 50 again takes up the initial position. One short stroke down and up of the lever 49 with the ridge 50 occurs once every five turns of the shaft.

V Adaptation to carding machines for automatic removal

from a canvas drum, characterized by the use of a slider 46, which is driven in reciprocating motion by means of a crank mechanism 44 and 45 from the canvas drum 38 and provided with a roller 47 in contact with the roller 48 attached to a lever 49 serving to rotate the tongue 50 on axis 52, whereby to bring the ridge 5Q to the initial position when the roller 48 is released, a spring 51 serves.
