Description

The proposed multi-milling machine differs from that described in patent number 200, mainly by the device of the device that gives the trust and other arrangement of the machine parts.

FIG. 1 shows a cross-section of the machine and FIG. 2 - view of half of the machine in the plan.

The machine, similar to that described in patent number 200, consists of two completely identical units sitting on a common shaft 6 and intended - one for processing trusts from the top, and another - for processing butt parts of trusts. The difference of one unit from another is purely internal, expressed mainly in the difference in the profiles of the working bodies and their relative speeds.

On the shaft b, for each unit, two disks 7, 7 are rigidly seated, in which in the sub-holders lie the necks of two diametrically opposed corrugated rollers 8, 8 and, moreover, in the disks, the ends of several of the mobile bars 9, 9 are strengthened .... At the inner ends of the axles of the rolls 8,8 there are

gears 10, which, when the working shaft 6 rotates, rolls along the brush 11 with internal gearing fixed fortified in the machine bed. Thanks to the specified coupling, 10, 11, rollers 8, while rotating with discs, have a second rotation around their axes. The rotation of the drums in both parts of the machine takes place in the direction opposite to the rotation of the drums of the main patent.

To the machine bed, above the discs 7.7, the arcs are reinforced, on which, at the top, the surface 12 is elastically corrugated, consisting of several strips, the reefs of which are coupled with the corrugations of the shafts 8.8. Thus, as the axis b rotates, the rollers of rollers 8.8 enter flutes in the grooves of surface 12, but do not touch them — in the space between the flutes and the valleys of the trust breaks.

The feeding device consists, for each unit of the machine, of the feed chuck 20, the guide rollers 19, 25 and the tension roller 23, covered

a belt 24 serving both units; The axis 18 of the pulley 20 is wired from the working axis of the machine 15 by means of a worm gear 16, 17.

The processing of the trusts is done by laying it in a vertical position at the roller 19 in the space between the belt 24 and the pulley 20, as a result of which the clamped between the belt and the pulley of the trust is inserted into the working part of the machine and in the first half (ab) of the rollers the second (6.8), due to the relative slip of the fiber between the working grooves, the rollers, besides the break, also also scraped wood from the fiber.

Upon exiting, the trusts at point (a) in the first half of the machine, the trust, is laid with the opposite ends into the second part of the machine, from which the fibers are cleared of wood, from both

the ends. In case of insufficiently clean processing, the process is repeated.

SUBJECT OF THE PATENT.

1. Modifying the milling machine according to patent No. 200, characterized in that the corrugated cylindrical surface 12 is fixed in the upper part of the machine, the drum of which with the corrugated rollers 8 and the scraper bars 9 rotates in the opposite direction to the rotation of the drum according to the basic patent. 2. With the use of a nutrient device for trusts indicated in paragraph 1 of the flap machine, which includes an endless feed belt 24, receiving movement from the pulley 20 placed on the vertical shaft and bypassing the guide pulleys 19 and 25 and the tension pulley 23.
