Container bag vacuum packaging machine for ultra-light powder

Abstract

The invention discloses a container bag vacuum packaging machine for ultra-light powder, which comprises a feeding device and a vacuum packaging chamber, wherein the feeding device consists of a feed hopper and a feed pipe, a vacuum pipe connected to a vacuum pump, a vacuum release pipe communicated with the atmosphere and a feed nozzle are arranged on the vacuum packaging chamber, air valves are arranged in the vacuum pipe and the vacuum release pipe, the feed pipe in the feeding device is connected with the feed nozzle, microporous drums rotating relatively and capable of exhausting air are arranged at the lower part of the feed hopper, and a screw is arranged at the inner part of the feed pipe. According to the container bag vacuum packaging machine, the microporous drums rotating relatively and capable of exhausting air in the feed hopper are used for extruding the ultra-light powder to exhaust, and the ultra-light powder is extruded again through the rotation of the screw and is conveyed, and the ultra-light powder products are sucked in the container bags of the vacuum packaging chamber through the pressure difference between the vacuum packaging chamber and the feeding device, thereby solving the difficult problems that the existing vacuum packaging machine has small package weight and cannot pre-extrude the powder.

Description

technical field [0001] The invention relates to a vacuum packaging machine, in particular to a bag-type vacuum packaging machine for vacuum packaging ultra-light powder materials. Background technique [0002] Existing vacuum packaging machines are mainly used for vacuum packaging of food in order to preserve quality and freshness. The packaging process is to directly vacuumize the packaging bag after the product is filled in the packaging bag to discharge the residual gas in the packaging bag, and then seal the packaging or put the packaging bag in the packaging room, and then vacuumize the packaging room to open the packaging bag, and heat and seal the packaging bag after filling the product; this kind of food vacuum packaging machine has a small vacuum packaging room and cannot be adjusted at will. , the packaging weight is limited by the packaging room, so it is not suitable for vacuum packaging of powder.

AI Technical Summary

Problems solved by technology

[0002] Existing vacuum packaging machines are mainly used for vacuum packaging of food in order to preserve quality and freshness. The packaging process is to directly vacuumize the packaging bag after the product is filled in the packaging bag to discharge the residual gas in the packaging bag, and then seal the packaging or put the packaging bag in the packaging room, and then vacuumize the packaging room to open the packaging bag, and heat and seal the packaging bag after filling the product; this kind of food vacuum packaging machine has a small vacuum packaging room and cannot be adjusted at will. , the packaging weight is limited by the packaging room, not suitable for vacuum packaging of powder

[0003] Some conventional bulk bag packaging machines for powder packaging do not use vacuum packaging, but use open packaging, or use screw rotary feed valve pocket packaging. These packaging methods are only suitable for some powders with high filling density and flow. Good powder, the dust pollution in the packaging process is serious, and the product packaging is not dense

[0004] The existing invention patent with the publication number of CN 1422782A discloses a powder vacuum packaging machine, which is composed of a feeding device, a vacuum packaging chamber and a dust collection device. The powder product is inhaled and placed in the packaging bag of the vacuum packaging room, and the powder is packaged in a closed vacuum state, which overcomes the shortcomings of traditional packaging machines with serious dust pollution

However, due to the loose nature of the powder, it is difficult to use this vacuum packaging machine to really fill the packaging bag, and the packaging weight is small, usually only 10kg, which is not suitable for container bags and needs further improvement.
