Abstract

Usage: production lines for the production of building blocks from wood and agricultural waste. The essence of the invention: the device is equipped with an emulsion supply unit with pipes and valves, perforated chambers, mobile molds, processing unit. When the molds are aligned with the locations of the pushers, the finished blocks are pushed down by means of drives to the receiving conveyors and sent to the warehouse 2 silt

Description

The invention relates to the woodworking industry and can be used in technological lines for the production of building blocks from wood and agricultural wastes.

The purpose of the invention is to increase productivity and improve the quality of building blocks by eliminating their destruction during unloading.

FIG. Figure 1 shows a device for the manufacture of building blocks, side view, longitudinal section; in Fig. 2, the same, top view.

A device for the manufacture of building blocks from wood or agricultural waste, comprises a housing 1, a feeder 2, an extrusion unit 3 with a vertical punch 4 and hollow cores 5, a heating unit 6, ejectors 7 and 8, and actuators 9-17.

The device is equipped with an emulsion supply unit 18 with pipes 19 and 20 and valves 21 and 22 perforated chambers 23 connected to the emulsion supply unit 18. The pressing unit 3 is made with horizontally movable molds 24 connected with the heating unit 6 and forming a ring transverse 25.26 and longitudinal 27, 28 channels for moving the molds 24, as well as the processing unit 29 of the molds 24 The punch 4 is placed in the feeder 2, and the core formers 5 are mounted on horizontal supports 30 installed in additional perforated chambers 23 The ejectors 7 and 8 are made vertical. The processing unit 29 of the molds 24 is mounted in front of the pressing unit 3, made in the form of chambers 31, having covers 32 with perforations 34 inclined to the side walls 33 and connected to the emulsion supply unit 18.

In order to move the ejected finished building blocks 35, under the ejector 7 and 8, receiving conveyors 36 and 37 are mounted. In the feed 1 there are 2 boosters 38 for feeding the raw material to the pressing unit 3. In the chambers 23 (there are perforations 39.

The drive 9 is designed to move the vertical punch 4, the drive 10 is for the void-forming 5, the drives 11 and 12 are for the ejector 7 and 8, the drives 13 and 14 are to move the molds 24 along the longitudinal channels 27 and 28, the drives 15, 16 - to move the mold 24 through the transverse channels 25 and 26, and the drive 17 - to rotate the boosters 38

The device works as follows.

The process proceeds continuously as the molds 24 move along the ring and in both directions, both to the right after the ejector 7 and to the left after the ejector 8. The molds 24 are sequentially pushed and moved cyclically one step with the help of drives 13 and 15, 14 and 16 along the longitudinal channels 27 and 28 and the transverse channels 25 and 26. The process begins after the ejector 7 in the position where the mold 24 is under the cover 32 and perforations 34, and the formers 5 on the support 30 are lowered by means of the drive 10 down and found TC inside the perforated chamber 23. In this position, the valves 21 and 22 of the emulsion supply unit 18 are opened and the emulsion (for example, KE-20-03) is briefly fed through the pipes 19 and 20 into the cover 32 and the chamber 23.

Through the perforations 34, the emulsion is sprayed onto the surface 33 of the walls of the molds 24, and through the perforations 39 the emulsion is sprayed onto the surface of the formers 5. With the actuator 10, the formers 5 are raised to the upper position. From the feeder 2, using drives 17, through the boosters 38, press mass is fed into the mold 24. Drive 9 lowers the punch 4 to the lower position and squeezes the press mass in the mold 24, then lowers the formers 5 to the lower position and drives 14 mold 24 one step and the loading cycle is repeated. As the molds 24 advance, they, along with the contents, are heated by the heaters of the heating unit 6 and gradually harden. When the next molds 24 are combined with the locations of the ejector 7 and 8, the finished blocks 35 are pushed down by means of the drives 11 and 12 to the receiving conveyors 36 and 37 and sent to the warehouse.
