Abstract

The invention relates to the production of building materials and can be used to make bricks and ceramic stones. The aim of the invention is to increase the reliability of operation. A rigid lever system for raising and lowering the receiving table was introduced into the installation for cutting products from a measuring bar. The reception table 4 is lowered forcibly by means of a rigid lever system consisting of two tons of grams, each of which has two pairs of levers and one end connected by levers to an axis 18, on which two double shoulders are fitted with rolling rollers in contact with cam, located on the low-speed shaft gear drive installation. 2 Il.

The invention relates to the building materials industry, namely to equipment for the production of bricks and similar products.

The aim of the invention is to increase the reliability of operation.

FIG. 1 shows the device, a general view; in fig. 2 shows a kinematic diagram of the mechanism for moving the receiving table.

The installation for cutting plastic products consists of a feeding conveyor 1, a pusher of a beam 2, a movable multi-stringed frame 3 with strings, a receiving little table 4 with a moveable little bar on it 5, a fixed table b, a limiting stop 7, a conveyor 8 of selection.

The pusher of the beam 2 has guides 9 and is connected through the axis 10, by means of the levers 11 and the gear 12, to the low-speed shaft of the drive reducer.

The receiving table 4 is made in the form of a roller table, in the walls of which there are grooves for accommodating the pull branches of the feeding conveyor 1. At the end of the receiving table 4 in the guides is placed on the rollers a table of separation of the beam 5.

The receiving table 4 is connected by levers 13 and 14 through bar 15, levers 16 and 17 with axis 18, on which two shoulders are mounted levers 19 and 20 with rolling rollers in contact with the cam 21 located on the low-speed gearbox shaft.

The multi-stringed frame 3 is mounted on rollers in guides 22 permanently mounted on frame 23 with the possibility of reciprocating movement therethrough by means of a system of levers 24 fixed on axis 25 connected by a pull 26 receiving rotational motion of cam 21.

Under the multi-stringed frame 3 on the frame 23 there is a fixed table 6, the rollers of which are mounted above the initial level of the rollers of the receiving table 4.

In the walls of the pull-out table 5, similarly to the receiving table 4, there are grooves for accommodating the pull branches of the conveyor 8 for selecting products.

The installation works as follows.

The beam from the cross-cutting mechanism is fed by the branch m of the conveyor 1 to the receiving table 4. The drive of the multi-string cutting device is activated. The low-speed shaft of the gearbox drive mechanism produces one cycle per cycle.

In the first half of the turn, table 4 is raised using a system of levers

13 and 14, tg 15, levers 16 and 17, axis 18, on which two shoulders levers 19 and 20 are mounted with run-in rollers alternately in contact with cam 21. Such a hard

The connection in the form of a lever system ensures reliable operation when raising and lowering the receiving table 4, since the forced lowering of the table with the help of a system of levers ensures uninterrupted operation of the installation.

The bar is removed from the feed conveyor 1.

Levers 11. driven by a pull 12 through axis 10, begin to move

pusher bar 2 along guides 9 in the direction of the dimensional bar. A bar is pushed over the rollers onto the fixed table 6. where there is already one bar.

The pusher of the bar 2 carries the bar on the bar on table 6. With the possibility of the latter passing through the cutting strings of the multi-stringed frame 3.

Strings when passing through the beam to reduce cutting effort and improve the quality of the cut beam move down together with the movable multi-stringed frame 3 under the action of the levers 24 through the pull 26. driven by the cam 21, and cut the measuring beam into

At the same time, the separation table of the beam 5 is brought to the fixed table 6 for receiving the cut timber.
