SU19953A1 - Bristle pulling machine - Google Patents

Description

The invention relates to machines for pulling out the bristles with two reels rotating in opposite directions. In the proposed maschine, one drum consists of rollers, pressed by springs from the center, and the other has fist protrusions, which seize the bristles when they run over the said: rollers.

In FIG. 1 shows a vertical section of the machine; FIG. 2-view of drum A with rollers; FIG. 3-view of a drum B fitted with cam projections.

In the proposed technique, intended for replacement of manual pulling out the bristles by the DP, the animal skin is thrown by the worker on the folding mechanism with shaft 3 and table 4, which is turned by pedal 2 on axis 1 in such a way that table 4 approaches the place where the bristle is grabbed, and shaft 3 presses against the shaft 5, the latter, rotating in the direction of the arrow, pulls the skin with the expansion of all the folds on it, as the worker presses the skin to the grooved shaft 13, rotating in the direction indicated by the arrow.

The bristles are captured due to the fact that the roller p rotating on the axis 7 of the drum A is calculated both from the circumferential speed and from the pitch so that they reach the protrusions r of the rotating drum B. near the gripping point of the bristle B. Once the roller p has seized the bristles, begins with a protrusion g move away to the axis 7, since the ends of the rollers are placed in the guide grooves with a pressure spring. Thus, when pulling the cheek down, with shafts 3 and 5, the bristle, pressed by the roller p to the protrusion g, will drag along puppy fetch vats. The bristles are pulled out during the rotation of the protrusions r falls on the conveyor 9, which, resting against the protrusion, moves in the direction of the arrow and, since this direction does not coincide with the rotation of the nest, the conveyor breaks off and, by spring 10, flips into the next nest. Tossing the conveyor should occur quickly enough so that the bristles are not carried back. Thus, the pulled out portions of the bristles from the other end of the conveyor 9 fall into a crate that is set high enough so that the bristles are not tangled.

The proposed machine is set in motion from the transmission through the pulley on the axle 11, from which the gear is transmitted. axis 7 and axis 8; from the same axis P, through the gear gear, rotation is transmitted to axis 12, from which shaft 5 and shaft 13 are driven through axis 1.

The subject of the patent.

A bristle pulling machine, consisting of two reversible rotatable drums, characterized in that one drum -4 is made of rollers p pressed by a center with springs, and the other araban B is equipped with cam lugs g for gripping the bristles them on rollers p.
