Automatic processing system for injection molding production of food-grade antibacterial plastic meal boxes

Abstract

The invention discloses an automatic processing system for injection molding production of food-grade antibacterial plastic meal boxes. The automatic processing system comprises H-shaped frames arranged in a bilateral symmetry mode and limiting devices arranged above the H-shaped frames, and a stacking device is arranged on the right sides of the H-shaped frames; through the cooperation of clamping plates, connecting springs, inclined plates and protrusions, the two sets of inclined plates can rotate around round pins under the elastic force effect of the connecting springs, so that the two sets of inclined plates can clamp the outer walls of plastic meal boxes of different sizes, the connecting springs have the buffering effect, the situation that the two sets of inclined plates are clamped too tightly, the to-be-processed plastic meal boxes are easy to deform or crack, the resources are wasted is prevented, friction force between the inclined plates and the outer walls of the to-be-processed plastic meal boxes can be increased through the protrusions, and the phenomenon that the to-be-processed plastic meal boxes shift or leak in the moving process is prevented.

Description

technical field [0001] The invention relates to the field of processing plastic lunch boxes, in particular to an automatic processing system for injection molding production of food-grade antibacterial plastic lunch boxes. Background technique [0002] Plastic lunch boxes are plastic containers made of food-grade plastic raw materials for the convenience of our takeaway food. It is a very common household plastic product in our daily life. It has a certain antibacterial effect and is also an indispensable plastic container for picnics or hiking. Plastic lunch boxes also have a variety of styles and sizes to choose from. Square plastic lunch boxes can be used to store various ingredients. Among them, rectangular plastic lunch boxes are easy to store moisture-rich foods, such as fruits, vegetables and seafood. Round plastic lunch boxes The boxes are perfect for sauces, sauces and side dishes of all kinds. [0003] The plastic lunch box is made by putting raw materials into t...

AI Technical Summary

Problems solved by technology

At present, manipulators are mostly used for automatic palletizing, which has high palletizing efficiency, but it can only grip plastic lunch boxes of a single specification, which cannot meet the production needs of plastic lunch boxes of other specifications, and the applicable occasions are low; existing palletizers Only a single plastic lunch box can be stacked, and multiple plastic lunch boxes cannot be blanked synchronously, which makes the stacking speed very fast, and manual handling is not enough, and the labor intensity is high, resulting in waste of time and reducing work. efficiency
