Packaging production method of water-soluble film product

Abstract

The invention discloses a packaging production method of a water-soluble film product. The packaging production method comprises the following steps that powder is put into a quantitative discharging mechanism; a driving shaft drives a rotating plate to rotate along a rotating groove through an opening and closing mechanism, so that a pair of electric heating plates conduct opening and closing movement, and after the electric heating plates are attached, a bottom transverse opening and side openings of a packaging bag strip are subjected to heat sealing; a motor drives the driving shaft to rotate to enable the electric heating plates to seal the bottom and the side walls of the packaging bag strip, the quantitative discharging mechanism intermittently and quantitatively puts powder into a hopper, and the hopper guides the powder into the packaging bag strip with the sealed bottom and the sealed side edges; the electric heating plates separate and loosen the packaging bag strip, meanwhile, the driving shaft drives a conveying mechanism to pull the packaging bag strip in a linkage manner, the filled powder moves to the bottoms of the electric heating plates, the electric heating plates are closed again to seal the packaging bag strip at the top of the powder, and the multiple products are continuously and hermetically packaged on the packaging bag strip; and the conveying mechanism conveys and enables the packaged products to enter a cut-off mechanism, and the driving shaft drives the cut-off mechanism to cut off packaging bag strips between the adjacent products in a linkage manner.

Description

technical field [0001] The invention relates to the technical field of water-soluble film products, in particular to a packaging production method for water-soluble film products. Background technique [0002] Water-soluble film products are often used in moisturizing bags, etc., that is, instant powder and water are packaged in the packaging bag of the water-soluble film inner bag. In the current packaging method, the powder discharge, packaging bag strips and sealing, conveying and cutting are all independent of each other. In the packaging process, the conveying and sealing are often not synchronized, the packaging bag is not sealed but the packaging bag strip has been conveyed away, resulting in the scattering of powder and water, and the amount of powder discharge cannot be controlled, which is prone to Empty packages and other phenomena, for this reason we propose a packaging production method for water-soluble film products to solve the above problems.
