SU25434A1 - Shoe Insoles Punching Machine - Google Patents

Description

The invention relates to a machine for pincing insoles of shoes consisting of a stand with a needle driven by a crank mechanism.

In the proposed machine, a pulley is used, designed to gradually move the insoles laid on its rim to the needle.

In the schematic drawing of FIG. 1 shows a front view of a car; FIG. 2 is a side view with a partial cut.

In the proposed shoe punching machine for insoles for shoes, a specially prepared insole 2 is placed on the grooved rim of pulley 1 and pressed against it by rollers 2 under the action of spring 13. A crankshaft 4 driven from pulley 5 through bevel gears b, b, gives a straight supply to the driver of the needle 7, which pierces the insole along the edge. After the needle moves back, the cam 8 rotating on the roller 9 weakens the pressing of the rollers 2 on the ratchet mechanism 10 and turns the pulley 1 together with the insole by the required amount; the rollers 2 at this time roll along the insole, maintaining its shape (bending along the rim profile) and position on the rim. The amount of rotation of the tongue can be adjusted by swapping the finger 11 on the disk of the rocker mechanism 12 connected to the ratchet. The position of the needle bar can vary in height due to raising or lowering the guide 13 of the rod 14, which is achieved by rotating the nut 15. The entire mechanism is mounted on the cast-iron base 16.

The subject matter of the invention.

A machine for pinning insoles of shoes, consisting of a bed with a needle, driven by a crank mechanism, characterized in that a pulley1 was used to puncture the insoles on the side of their cut, designed to gradually move the insoles on the rim 2 to the needle 7, with the assistance of pressure spring rollers 2, by means of the ratchet mechanism 10, 11, 12 from the drive shaft 4.
