Degradable plastic self-sealing bag plastic sealing strip pasting device and pasting process

Abstract

The invention relates to the technical field of degradable plastic self-sealing bag production, and discloses a degradable plastic self-sealing bag plastic sealing strip pasting device and pasting process. The degradable plastic self-sealing bag plastic sealing strip pasting device comprises a bottom end fixing plate, folding roller driving motors, a rolling driving motor and a cutting driving motor, wherein a pasting operation table is fixedly arranged on the bottom end fixing plate; and a plastic sealing strip feeder, a hot-pressing pasting device and a cutter are sequentially arranged on the pasting operation table from left to right. Through the combined action of a power transmission mechanism and a gear box, the moving distance of a movable feeding table together with a three-phase laminating device can be completely the same as the moving distance of a fixing disc; and the operation to measure the length of a reel sleeve of a degradable plastic thin film at first and then to adjust the position of the entire movable feeding table together with the three-phase laminating device is not needed, so that errors in the measuring and adjusting process can be avoided when the working procedure is reduced, it can be guaranteed that the plastic sealing strip pasting position exists at the end part of the plastic thin film, the use of plastic thin films of larger specifications is not needed for the production of plastic self-sealing bags, and the raw material cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of production of degradable plastic ziplock bags, in particular to equipment and a pasting process for pasting plastic seal strips of degradable plastic ziplock bags. Background technique [0002] Degradable plastics, also known as biodegradable plastics, refer to the degradation caused by the action of microorganisms existing in nature under natural conditions such as soil or sand, or under specific conditions such as composting conditions or anaerobic digestion conditions or in aqueous culture fluids, and Plastics that eventually completely degrade into carbon dioxide, methane, water and mineralized inorganic salts of the elements they contain, as well as new biomass. There are many production styles of degradable plastic bags, such as vest bags, straight bags, ziplock bags, etc. Wherein the ziplock bag has been widely used because it can be sealed by itself. [0003] In the production process of degrada...
