Description

Technical Field

[0001] The utility model relates to the technical field of novel paper tray packaging, in particular to a paper bowl detection device. Background Art

[0002] In the production of paper cups and bowls, a laminating machine is used to coat one or both sides of the base paper with PE to obtain PE coated paper, which is then slit and die-cut, and finally pressed into shape. In the forming of paper bowls, the die-cut rectangular or fan-shaped paper pieces are rolled and bonded into paper walls, and then bonded to the preheated cup bottom. At present, the cutting and bonding in the production of paper cups and bowls have the ability of automated production processes. While mass-producing efficiently, more attention should be paid to quality, so the inspection of paper cups and bowls is particularly important.

[0003] The patent document with publication number CN102539445A in the prior art provides a paper cup and bowl inspection machine. The device sets a cup feeding station on the dividing plate, and installs a vacuum cover under the cup feeding station to adsorb the bottom of the cup using the principle of negative pressure adsorption, and identifies paper cups and bowls with defects such as false adhesion, no adhesion, and loose adhesion of the bottom of the cup for inspection. The device has negative pressure detection, image detection, etc., which improves the inspection function of paper cups and bowls. However, the destructive negative pressure detection method adopted in the device only detects the adhesion seal of the bottom of the cup, and lacks the inspection of the cup wall, resulting in a small inspection range, poor inspection effect, and easy damage to qualified paper cups and bowls. And after the inspection, the common paper bowls on the market are packaged by manual packaging machines, and manual counting is required before packaging, but this method is inefficient and it is necessary to improve it.
