The ends of the guide rods are commonly connected to a limiting block for supporting the paper bowl, and a lower mold for placing the paper bowl is arranged at the lower end of the limiting block. The limiting block is elastically connected to the electric heating block through a plurality of guide rods and a plurality of compression springs. During use, the limiting block presses down into the paper bowl. The limiting block moves along with the guide rod, reducing the friction between the electric heating block and the limiting aluminum ring while ensuring fixation, and also reducing the loss of the equipment; there is a margin between the guide rod and the electric heating block, and the limiting block will descend successively according to the different frictions of the inner wall of the paper bowl, which can adapt to the production of paper bowls with different wall thicknesses. The above device has some problems. When the device is in use, the limiting block is pressed down into the paper bowl. Although the limiting block can move well inside the paper bowl to limit the paper bowl, during use, the movement of the limiting block may push against the inner wall of the paper bowl, causing the paper bowl to deform, resulting in the final product of the paper bowl being difficult to meet the established expectations. Therefore, we propose a limiting device for the bowl mouth of a paper bowl to solve the above-mentioned problems. Content of the Utility Model
