The invention relates to the industry of building materials and can be used in the manufacture of products from plastic masses, for example, asbestos-cement, asbestos silicate, gypsum-concrete, etc.

The aim of the invention is to increase productivity and improve product quality.

FIG. shows the installation with the lower entry of reinforcement into the extruder, side view; figure 2 - the same, with the top input of the reinforcement in the extruder; on fig.Z - section aa in figure 2; in Fig.4 section bB in Fig.2; on fig.Z - node 1 in figure 1.

The installation comprises an extruder 1, guides 2 for insertion of reinforcement, a press head 3 with a mouthpiece 4, a mechanism 5 for inserting reinforcement and a conveyor 6 for supplying reinforcement, over which reinforcement accumulator 7 is installed. Mechanism 5 for insertion of reinforcement consists of a frame 8 on which cut-off segment segments are installed on the drive shaft 9; : sheave pulleys 10, over which grooved rollers I are located, bearing housings of which are fixed to the frame through spring dampers 12. Shaft 9 is connected to drive 13. On frame 8, in front of guides 2 for insertion of reinforcement into extruder 1, there is a folding stop 14 with mechanism 15 control, remotely connected to the length of the product I6 installed behind the outlet of the mouthpiece 4. Segmented pulleys 10, in the initial position facing the cut off part to the spring-loaded grooved rollers 11, allow free passage a rmatury at

19 and driven segmental drums 20 having a circumference of the working part not exceeding the distance from the folding stop to the outlet of the extruder 1. The mechanism 5 for inserting the armature into the extruder is made in the form of driving segmented pulleys 10 and grooved rollers spring-loaded to them. 5 il.

it is fed to the folding stop 14 and exported together with the weight. The conveyor feed conveyor 6 consists of a frame 17 on which grooved rollers 19 are mounted in rolling bearings 18, which are forced to rotate by interacting with rolling segmented drums 20 connected to each other by a chain drive 21 with a drive 22. Segmental The reels 20 in the initial position do not prevent the free rotation of the rollers when the mechanism 5 for inserting the reinforcement into the extruder is triggered and when the reinforcement is extruded with the product. The length of the arc of a circle of the segment drums is chosen to slightly exceed the front end of the reinforcement to the folding stop 14 in order to guarantee the transfer of all the bars of the reinforcement to the plane of the stop, where they align exactly on one line parallel to the axis of rotation of the rotor. On the end parts of the conveyor 6 pivoting stops 23 are installed, which interact with limit switches 24. Restores the products with individual measuring rods 23 stops. set along the width of the conveyor - along the axis of the grooves of all the rollers. When reinforcing products with a grid or frame, the stops can be installed along the width of the conveyor only along the axis of the grooves of the outer rollers. The resetting of the stops 23, each installed on its rolling support 25 and associated with its limit switch 24, is returned to the starting position by means of a spring 26, which is regulated by a screw 27. Device 28 serves to receive the products.

The installation works as follows.

By the accumulator 7, the reinforcement is lowered into the grooves of the rollers 11 of the conveyor feed conveyor 6. At the same time, the valve presses the plates of the pivoting stops 23, which, when rotated, close the limit switches 24, which enable the drive of the 22 segment reels 20. The drive starts if all the limit switches 24 installed at the front and rear ends of the conveyor are activated.

The segmented drums 20 make one turn and, interacting with the rollers of the conveyor 6, transfer the armature to the folding stop 14. Next, the drive of the 13 segment pulleys 10 is turned on, which, having made one turn, feed the armature through the guides 2 into the mouthpiece 4 of the extruder 1, into which the moldable mass is simultaneously injected. Further movement of the reinforcement with the moldable bar is carried out by compressing it in the mouthpiece. The cutting of a bar into dimensional products is carried out on the intervals created between the rear and front ends of the reinforcement supplied to the extruder. After passing the end of the reinforcement to the guides 2, the folding stop 14 returns to its original vertical position. Further, the reinforcement supply operations are repeated in the predetermined after

consensus, i.e. after receiving the signal from the counter 16 of length about exiting the mouthpiece 4 of the bar of the required length, the folding stop 14 is translated into a horizontal position and the mechanism 5 for inserting the valve into the extruder.
