Abstract

This invention relates to devices for vacuum packaging bulk materials. The aim of the invention is the expansion of technological capabilities by ensuring the packaging of bulk materials that do not form the arch, and ease of use. The bottom 3 with the container mounted on it presses against the casing 8. This closes the opening in the bottom under the container and at the same time opens the valve, interconnecting the chamber with the vacuum. The bulk material is sucked into the container through the nipple 2. After filling the container, the stem 5 is lowered and opens the hole in the bottom under the container. (L

The invention relates to packaging equipment, in particular, to devices for vacuum packaging of raw materials.

; The purpose of the invention is to simplify the design, improve performance and expand technological capabilities by enabling the packaging of bulk materials that do not form a vault.

Making the nozzle closed with the upper part and having horizontally located holes and the bottom, having an opening for air passage and connected to the rod by means of an elastic disk with an opening, the stem being installed with the possibility of free-running vacuum discharge in the chamber forming rvod.

The drawing shows a device for vacuum packaging bulk materials, a general view.

The device consists of a hopper I, an outlet 2, a chamber 3 with a bottom with a gasket of elastic material 4, the rod 5 is connected to the table with rubber discs 6 with an opening for air passage. Such a connection between the rod and the bottom of the chamber allows the rod to have a free stroke for opening the valve 7, through which the vacuum a is released. The camera will restrict ta to the casing 8.

The device works as follows,

The container is installed on the bottom of chamber 3, compressed air is supplied, the bottom of the lift pro- props. When preload

the bottom of the casing 8 is overlapped from the bottom of the container under the container and at the same time the pneumatic valve is unlocked, together with the camera with a vacuum. The bulk material is sucked into the container through the nozzle 2. The filling is controlled by vacuum and by time. After filling the container, the shaft 5 is lowered and the hole in the bottom under the container is opened, connecting the space of the chamber with the atmosphere. Upon further lowering of the rod, the bottom is lowered with the container full. The bulk material in the hopper is held by the horizontal openings of the nozzle due to the angle of repose of the powdered material.
