Description

Technical Field

[0001] The utility model relates to the technical field of carton production, in particular to a drop-type paper receiving machine. Background Technique

[0002] As a packaging product for protecting goods, cartons run through the entire process of commodity circulation. Cartons are generally made by pasting and folding cardboard into a cylindrical shape. The cylindrical cardboard after pasting and folding generally passes through a conveyor belt in sequence and falls into a paper receiving mechanism at the end of the conveyor belt, so that multiple cylindrical cardboards are stacked together to form a stack. Each stack of cardboard is then transported to a bundling machine, which completes the bundling. After retrieval, the patent with the publication number of CN117002804B discloses a front paper separating mechanism and a drop-type paper receiving machine including the same. When in use, when waiting for paper separation, the horizontal telescopic rod of the horizontal telescopic assembly retracts, and the vertical telescopic rod of the vertical telescopic assembly extends; when separating paper, the horizontal telescopic rod of the horizontal telescopic assembly extends, and the vertical telescopic rod of the vertical telescopic assembly retracts. The horizontal telescopic assembly and the vertical telescopic assembly are arranged at an angle, and can make the front paper separating piece just below the cardboard when waiting for the paper receiving board. As the cardboard moves forward, the front paper separating piece extends synchronously, and thus can accurately separate the paper. When not separating paper, the front paper separating piece is hidden under the conveyor belt and will not interfere with the transportation of the cardboard. However, since the cardboard formed into a cylindrical shape is relatively fluffy after folding, although each time a cardboard falls, there will be a pressure on the cardboard on the lower side, but this pressure is small, and the whole stack of cardboard is still relatively fluffy, which will affect the subsequent falling cardboard. At the same time, during the conveying process, the friction force between the cardboard at the top and the cardboard at the lower side is not enough to offset the friction force given by the conveyor belt below, so there will be an overall offset. For this reason, a drop-type paper receiving machine is designed, which is convenient to pat the paper once every time it falls, improves the tightness of each stack of cardboard, is convenient to separate the paper during the falling process, ensures the continuous conveying of the cardboard, and clamps and conveys a stack of cardboard during the horizontal conveying process to improve the conveying stability of each stack of cartons.
