Problems solved by technology
[0002] Existing vacuum packaging machines are mainly used for vacuum packaging of food in order to preserve the quality and freshness; the packaging process is to vacuumize the packaging bag after the product is filled in the packaging bag, remove the residual gas in the packaging bag and then seal the packaging bag; Or put the packaging bag in the packaging room, then vacuum the packaging room to open the packaging bag, and heat and seal the packaging bag after the product is filled; the vacuum packaging room of this food vacuum packaging machine is small and cannot be adjusted at will. Weight is limited by the packaging room; not suitable for vacuum packaging of powders
The existing powder materials are not packaged in vacuum, and the packaging of powder materials is generally open-top packaging; or it is packaged in pockets with screw rotary feed valves. During the packaging process, the dust pollution is serious, the measurement is inaccurate, and the product packaging is not dense.

Embodiment Construction
[0014] Such as figure 1 , figure 2 As shown, the present embodiment consists of a support, a feeding device, a vacuum packaging chamber, a dust collecting device and a weighing device. A vacuum tube 2, a vacuum release tube 3 and a feed nozzle 25 are installed on the vacuum packaging chamber 1, and the vacuum tube is connected to a vacuum pump. A valve 13 is installed on the vacuum tube 2. When the packaging machine is working, the valve 13 is opened, and the vacuum packaging Chamber 1 is vacuumed; vacuum release pipe 3 communicates with the atmosphere and a valve 12 is also installed in the pipe. The vacuum release pipe is used to ensure the stability of the vacuum degree in the vacuum packaging chamber. When the vacuum in the vacuum packaging chamber is too high When the vacuum is low, the valve 12 is opened to reduce the vacuum in the vacuum packaging chamber 1, and it is closed when the vacuum is low, so as to ensure the stability of the pressure in the vacuum packaging ...

The invention discloses a powder vacuum packaging machine, which includes a support, a feeding device, a vacuum packaging room and a dust collection device, the vacuum packaging room is provided with a vacuum tube connected to a vacuum pump, a vacuum release tube connected to the atmosphere and The feed nozzle, the vacuum tube and the vacuum release tube are provided with a valve, the feed tube in the feeding device is provided with a feed valve, and the feed tube is connected with the feed nozzle; the dust collection device is connected with the suction The dust removal pipe connected to the air pump is composed of a dust removal hood. There is a valve on the dust removal pipe. The dust removal pipe is located at the bottom of the vacuum packaging room and extends into the vacuum packaging room. The dust removal cover is located directly above the top of the vacuum packaging room. The invention utilizes the pressure difference between the vacuum packaging chamber and the feeding device to suck the powder product into the packaging bag of the vacuum packaging chamber, realize the packaging of the powder in a closed vacuum state, and overcome the traditional packing machine The disadvantages of small weight and serious dust pollution.
Description
Technical field [0001] The invention relates to a vacuum packaging machine, in particular to a vacuum packaging machine for vacuum packaging ultrafine powder materials. Background technique [0002] Existing vacuum packaging machines are mainly used for vacuum packaging of food in order to preserve the quality and freshness; the packaging process is to vacuumize the packaging bag after the product is filled in the packaging bag, remove the residual gas in the packaging bag and then seal the packaging bag; Or put the packaging bag in the packaging room, then vacuum the packaging room to open the packaging bag, and heat and seal the packaging bag after the product is filled; the vacuum packaging room of this food vacuum packaging machine is small and cannot be adjusted at will. The weight is limited by the packaging room; not suitable for vacuum packaging of powders. Existing powder materials are not packaged in vacuum, and the packaging of powder materials is generally open-...
