Automatic high-speed conveyer system of EPS (Expandable Polystyrene) cup printing machine

Abstract

The invention relates to a cup and bowl printing machine, in particular to an automatic high-speed conveyer system of an EPS (Expandable Polystyrene) cup printing machine, mainly comprising an automatic high-speed cup separating device, an automatic high-speed cup receiving and sending device, an automatic high-speed cup stacking and conveying device, an automatic high-speed cup counting and pushing device and a PLC (Programmable Logic Controller) controller, wherein the automatic high-speed cup separating device separates conveyed cups to be printed, which are sleeved and stacked into a whole strip, into single cups and conveys the cups into a mould of a eight-graduation turntable of a stepper graduator for printing; the printed cups are conveyed to the automatic high-speed cup stacking device through the automatic high-speed cup receiving and sending device; the automatic high-speed cup stacking device sleeves and stacks the cups into a whole cup strip and pushes the cup strip to the automatic high-speed cup counting and pushing device; and after counting, the cups are pushed to a cup receiving groove. The whole process is controlled by the PLC controller to realize the automation of the whole printing process, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a printing machine, in particular to a cup and bowl printing machine (also called a curved surface offset printing machine) for printing EPS cups and bowls (i.e., foam cups and bowls), which can automatically divide cups and send cups, receive cups, send cups, stack cups and The automatic high-speed conveying system of the EPS cup printing machine that pushes the whole cup to the cup collection groove after counting. Background technique [0002] Because the printing surface of EPS cups and bowls is different from other plastics, especially its material is particularly brittle, the spiral cup feeding of conventional cups and bowls printing machines is easy to damage the cup rim of EPS cups and bowls. Because the conventional cup and bowl printing machine uses a concave-convex conveyor belt to pick up the cups, the cup rim will be damaged, and a single cup cannot be stacked automatically after entering the conveyor belt. Can't ...

[0002] Because the printing surface of EPS cups and bowls is different from other plastics, especially its material is particularly brittle, the spiral cup feeding of conventional cups and bowls printing machines is easy to damage the edge of EPS cups and bowls

Because the conventional cup and bowl printing machine uses a concave-convex conveyor belt to pick up the cups, the cup rim will be damaged, and a single cup cannot be stacked automatically after entering the conveyor belt. Can't push away, in summary, the traditional automatic device can't complete the automatic high-speed division of EPS cups and bowls, sending cups, receiving cups, sending cups, stacking cups, and pushing the whole cup counted to the cup collection slot At present, domestically printed EPS cups and bowls do not have an automatic device after the cups are printed and can only pick up the cups manually. The existing technology in developed countries in foreign countries completes the above process with robotic hands, but the robotic hands cannot meet the high-speed requirements.

[0003] It can be seen that the above-mentioned existing EPS cup printing machine still has inconvenience and defects in dividing cups, sending cups, receiving cups, sending cups, stacking cups and points, and needs to be further improved urgently.

In order to solve the problem of automatic high-speed transmission of EPS cup printing machines, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time. This is obviously a problem that relevant manufacturers are eager to solve.
