Description

The proposed machine aims to achieve the desired size in the width and length of the shaft of the boot and to give it a beautiful look by eliminating excessive thickness at the top of the shaft.

In FIG. 1 shows a front view of a car; Fig, 2 is a side view of it.

Two legs-slider 3, which are connected by bolt-1-h. 8, are screwed to the cast-iron table 2, mounted on legs 1, str for dl, stiffness bolts 4. Four metal rollers 6, rotated on bearings, each on their axes, rotate rounded 1, screwed protrusions. All four rollers of the same diameter.

On the outer side of the rack, gears 14 and, besides / earrings 19, are put on the outstanding ends of the rollers. Other ends hold movable axes 18 of parasitic gears, engaging) & giving all the rollers 6 in one direction.

The presence of earrings allows rollers to b

diverge and go independently

from a friend, not rubbed with this movement

clutch gears 14, move. together with them.

The load 12, which is seated on the lever 11, which has a point of support on the bolt 8, causes the inner rollers to diverge, pulling at the shaft.

The rollers are driven in rotation from the belt drive, for which the lower roller is elongated and a pulley 20 is seated on it. The end of the roller is resting in the bearing of the rack 7.

The length of the rollers and their thread depend on the size and grade of the boot; a heavy rough boot will roll out on large rollers with coarse, high threads; lightweight boots of pure wool - on rollers with a smaller and leaning thread.

The operation of the machine is as follows: a batted boot that has been worn on a hammer and washing machine and has a narrow and short bootleg, and on top of the excess thickness, is put on the middle two rollers 6, which have screw lugs and can move between them and move apart. On the boot boot, put on these two rollers, they gave the same two rollers, one from the bottom, the other from the top.

 All four working rollers have a rotation in one direction. Since the area of engagement of the middle rollers with respect to the outer ones is much larger. And {besides, on the middle rollers the shaft will always be tight, there will be no slipping of the shaft to be machined in the car. The tops will always experience tension from the middle rollers due to the fact that the load will cause them to diverge and the tops to expand along the entire length.

The presence of protrusions on the rollers and their rotation in the direction of the thread of the protrusions make it possible to roll out the shaft, pull it along and smooth out the unevenness of the boot, which was obtained during the previous processing.

The subject matter of the invention.

A machine for treating the boot of a high-felt boot, distinguished using four metal rollers b,

fitted with protrusions along a helical line and located one above the other, of which the lower roller rotates in stationary bearing, and the upper rollers are placed in a movable along vertical guides pchschipniki 5, 5 and receive rotation from the lower roller using gears 14 of wheels mounted on the axle rollers, as well as intermediate wheels 18, the axes of which are connected to each other and to the axles of the rollers with earrings 19; For pushing apart the rollers, a lever 11 with a counterweight 12 is used.
