Description

Technical Field

[0001] The utility model relates to the technical field of paper bowl detection equipment, in particular to a paper bowl strength testing device. Background Art

[0002] With the rise of the takeout catering industry, delivery personnel need to carry food boxes to the customer's location. Delivery personnel often stack the food boxes in delivery boxes for transportation. The food boxes at the bottom will bear the pressure of the food on the top. If the pressure resistance of the food boxes is insufficient, the food boxes will deform and the food in the food boxes will overflow. Therefore, there are strict requirements on the quality of food boxes. Paper bowls are a common type of food boxes.

[0003] When conducting strength tests on existing paper bowls, the top cover of the paper bowl is squeezed by a flat device to test the compression resistance of the paper bowl. However, in the actual placement of paper bowls, the stacked paper bowls are squeezed by the top and bottom of the paper bowls, and the outer edge of the bottom of the paper bowl is circular with a small support surface. The existing paper bowl strength testing device does not simulate the support surface of the paper bowl, so the test results are different from the compression resistance of the actual paper bowl, which affects the use effect of the paper bowl. For this reason, we propose a paper bowl strength testing device. Utility Model Content
