Description

rotation with a frequency of 120-130 revolutions per 1 min due to the drive and provided with a casing consisting of the left 11 and right 12 halves. On the left half of the casing a curtain 13 is made of elastic material, for example of rubber sheet or of a conveyor belt, and On the right half of the casing, inclined blades 14 are mounted on its inner surface, which can be made of sheet material, for example steel sheet 1.5-2 mm thick. The most optimal blade width is 30-40 mm, and the distance between the blades is - 20-35 mm (figure 4). The blades can be installed with the ability to tilt them by turning. The number of blades may be different depending on the height and inclination of the sides of the form 15, the width of which, together with the sides, is covered by a brush 10.

The device can be made stationary or mobile.

The device works as follows.

During operation, from the tank 1, the wax emulsion grease 2 flows by gravity through the open electrically controlled valve 3 to the gate batching pump 4, which has the required capacity and delivers the lubricant through the flexible hose 5 to the perforated distributor 6, from which it expires through ring glands nozzle walls 7 and cleaning pins 8 holes. The lubricant enters the pile of the rotating brush 10 through the gap between the left 11 and right 12 halves of the casing. At the same time, the cleaners of the holes 8 are in contact with the free end of the brush bristle and due to this they oscillate in the holes of the nozzles 7, ensuring a constant cleaning of these holes, which is especially important when using wax water-based lubricants, which dry on air during technological and other breaks. in the operation of the device, they give a hard film capable of blocking the nozzles of the nozzles, and this would lead to an uneven supply of lubricant to the brush. Moistened with grease, the pile of the rotating brush 10 is contacted in a contact manner with a thin layer on

The working surfaces of the mold 15 moving under the brush, while the part of the pile that meets the inclined blades 14 in its path, changes the direction of its movement, is thrown by these blades to the sides of the mold due to centrifugal rotational forces, and with force comes into contact with the flange. lubricant applied to them. Thus, with a single brush, the mold tray is greased.

and its sides, and due to the high mobility of the pile it is possible to apply lubricant to the relief surfaces.

When the device is turned off, the electropullable valve 2 closes, preventing spontaneous lubricant flow under the force of gravity, the metering pump 4 and the brush stop, the outflow of lubricant from the distributor 6 stops, but the distributor remains

filled with grease, since, due to the small cross-sectional area of the discharge ports, the grease is locked inside the distributor by external atmospheric air. The next time you turn on the device, the dispenser immediately issues lubricant to the brush.
