Description

one

The invention relates to packaging equipment and is intended for packaging bulk materials in bags of heat-sealable material.

A device for manufacturing, filling and sealing packages of heat-sealing material is known, comprising a roll holder of a flat-laid sleeve, guide rollers, a device for forming transverse seams, mechanisms for notching and welding the side surface of the sleeve, a device for separating the finished packages from one another, and a bunker with a supply pipe .

When the bags are filled with strongly dusty and easily electrified materials, the seams on the bag are fragile, since the particles of the material settle on the walls of the bag and interfere with the heat sealing of the seams.

The purpose of the invention is to improve the quality of the schv on bags of heat-adhesive material when filled with a non-electrifying electrifying material.

To do this, the end of the supply pipe is bent at a right angle and is parallel to the axis of movement of the packaging material, and the mechanisms for notching and welding the side surface of the sleeve are installed with two diametrically opposite

sides of the threading pipeline before it bends.

In addition, the hopper with the material to be packaged is equipped with a sluice gate and is connected to an air source through an intermediate tank.

The drawing schematically shows the proposed device.

The device includes a roll holder of a flat-laid sleeve 1, a device 2 for forming transverse seams, a hopper with supply pipe 4, a mechanism 5 for notching the side surface of the sleeve, a mechanism 6 for welding the side surface of the sleeve, guiding the roller 7 n device 8 for separating the packages from one another. .

The bunker is equipped with a l: shutter valve 9 and is connected through an intermediate tank 10 with a source of compressed air.

The mechanisms 5 and 6 for notching and welding the side surface of the sleeve are located on two diametrically opposite sides of the supply pipeline in front of its pipeline.

The device works as follows.

The packaging material is fed from the roll and passes through the device 2, and transverse seams are formed on the surface of the sleeve (which does not reach the end by 30-35%).

Then, the mechanism 5 makes an incision on the side surface of the sleeve, and through this notch, as well as through not completely welded transverse seams, the supply pipe 4 is inserted into the sleeve, and as the packaging material advances, the bags are filled. The notch immediately after insertion of the conduit 4 inside the sleeve is sealed by the mechanism 6. Using the device 8, the cross-section hole is fully sealed across the entire width of the sleeve and the filled bags are separated from one another. The bags are filled with material through an intermediate / O tank connected to a source of compressed air.
