Packaging machine used for packaging powdery material

Abstract

The invention discloses a packaging machine used for packaging a powdery material. The packaging machine is characterized by structurally comprising an equipment main body, a control panel, a heat seal, a protective cover, a finished product outlet, a feed box, a ring shaking device, a storage hopper and a supporting frame. The packaging machine has the beneficial effects that: a blowing and stroking structure is matched with a limiting layer, so that powder can be effectively blown and swept off, and therefore, the heat seal is prevented from being mixed with part of powder; moreover, duringthermal treatment on a packaging bag, the problem that package has a gas leakage phenomenon as mixed powder has heat seal blocking effect after heat seal is avoided; meanwhile, under action of a stroking rod, blocky powder inside the powder is refined and smashed; elastic acting force of an elastic strip is applied on the lower surface of the hopper under matching with a buckle contact assembly ofan elastic stripping mechanism, so that powder on the surface of the hopper is subjected to accelerated shake-off treatment; and meanwhile, diffusion effect of heat energy of a heating roller is matched, so that the powder is always in a dry state, and therefore, a wetting phenomenon is avoided.

Description

technical field [0001] The invention relates to the field of food packaging, more specifically, a packaging machine for packaging powder. Background technique [0002] In terms of flour processing technology, in order to ensure the effective preservation of flour, it is necessary to use a packaging machine to tightly package the flour to prevent the flour from being exposed to the air and cannot be stored for a longer period of time. When packaging, the following defects often appear: [0003] 1. When the powder is poured, due to its light weight, it will have an impact-like upward effect when it is poured into the package, and at the same time as it is lifted and introduced, some powder will directly stay in the heat-sealed opening of the packaging bag As a result, when the packaging bag is heat-sealed, due to the mixed powder, the heat-sealing is not tight and the packaging leaks. [0004] 2. In the process of blanking, due to the concentrated push-down of the powder, an...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a packaging machine for packaging powders, so as to solve the problem that the powder in the prior art is poured into the packaging due to its light weight when it is poured into the package. When the packaging bag is heat-sealed, there will be an impact-type lifting effect, and at the same time as the lifting and introduction, some powder will directly stay at the heat-sealed opening of the packaging bag, which will cause some problems due to the mixed powder when the packaging bag is heat-sealed. In the process of unloading, due to the concentrated push-down of the powder, and under the action of its own characteristics, it is easy to appear that the bottom powder is partially stagnant and in the process of pushing down. The powder on the surface of the material plate cannot fall autonomously. As a result, during the secondary blanking, due to the presence of the stagnant powder, there will be a tendency for the metering of the powder to be too much this time, and due to the stagnant powder Exposure to the air for a long time will cause the defect of moisture in this part of the powder
