Description

TECHNICAL FIELD

[0001] The utility model relates to packing device technical field, concretely relates to a kind of water-absorbent resin packing device. BACKGROUND

[0002] Water-absorbent resin is a new type of functional polymer material. It has the function of absorbing several hundred to several thousand times of water than itself, and has excellent water retention performance. Once it swells into hydrogel, it is difficult to separate water even under pressure. High water-absorbent resin is a functional polymer material with a large number of hydrophilic groups.

[0003] When the water-absorbent resin is transported after production, in order to prevent the water-absorbent resin from being physically damaged by being exposed to air for a long time, or to prevent the water-absorbent resin from being affected by subsequent use due to moisture caused by contact with moisture in the air during transportation, the water-absorbent resin needs to be transported by sealing and storing method.

[0004] The existing packaging of water-absorbent resin usually uses transparent plastic film for packaging. The use cost of plastic film is low, and the plastic film can keep the resin clean and prevent pollution and moisture penetration. When the plastic film is used by hand to package the water-absorbent resin, the water-absorbent resin needs to be placed in the plastic film first, and then the opening of the plastic film is pinched by hand to prevent the water-absorbent resin from falling off. Then the plastic film is taken to the sealing machine for sealing. During the sealing process, the plastic film needs to be continuously pinched by hand, which is more complicated and cannot improve the packaging efficiency of the water-absorbent resin by hand.
