One-mold-time six-action thermal forming in-mold labeling, conveying and boxing production line and operation method

Abstract

The invention relates to a one-mold-time six-action thermal forming in-mold labeling, conveying and boxing production line and an operation method thereof. The operation method comprises the followingactions that (1) mold opening is conducted, wherein a lower mold descends, a product is demolded, and an in-mold labeling, material taking and conveying manipulator acts and prepares to enter a mold;(2) the in-mold labeling, material taking and conveying manipulator enters a mold body through translation; (3) the lower mold rises for label taking, and a sucker of a cup-making pull-up built-in material taking and discharging device is descended to unload cups; (4) the lower mold descends after label taking is completed, and the cup-making pull-up built-in material taking and discharging device is reset; (5) translation and resetting of an in-mold labeling, material taking and conveying manipulator are achieved; and (6) the lower mold and an upper mold are assembled to form a product. According to the one-mold-time six-action thermal forming in-mold labeling, conveying and boxing production line and the operation method thereof, in the in-mold labeling process, the step that a multifunctional material taking and conveying manipulator takes out a product from a cup making mold and descends is omitted, and compared with the prior art, only six actions are needed, such that only six actions are needed for each mold time, the action process is simpler, and the production efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of production and packaging of plastic containers, in particular to an air-pressed thermoforming in-mold labeling transfer packing production line and an operating method thereof. Background technique [0002] Disposable plastic catering utensils for daily use, such as disposable cups, bowls, boxes, covers, boxes and other products, the production methods of such disposable plastic containers and cover utensils in the prior art mainly include air pressure thermoforming, blister Formed products, if these products need label patterns, they can print graphics on the curved surface or add self-adhesive labels or heat shrinkable film decoration. The more advanced is the production of in-mold labeling and molding. Although the raw materials of injection molding have no corners and edges Angle crushing and sheet material use electricity, but the mold is expensive, the mold processing and debugging cycle is long, an...

AI Technical Summary

Problems solved by technology

[0003] Therefore, in view of the existing problems in the prior art, especially for cup products including curved surface printed container products, with the improvement of social consumption level, consumers also gradually increase the demand for product appearance and packaging, so that the existing The market share of the pressure-air thermoforming container of the production process has dropped sharply. In order to save the problem of the decline in the market share of cup-making products, foreign countries have launched a film-pressed thermoforming in-mold labeling production line, but there are still high prices and no multi-function. Use and other issues, in order to make product labeling to meet consumers' requirements for high-end products and regain market share, it is urgent to provide a cup-making machine that can use the existing cup making machine to ensure low input costs and low mold modification costs. The short cycle is more conducive to seizing market opportunities, increasing the added value of products, and is conducive to the streamlined production line and high work efficiency cup mold technology
