Description

Technical Field

[0001] The utility model relates to the technical field of paper product manufacturing, in particular to an automatic feeding mechanism. Background Art

[0002] Paper products refer to various products made from processed and treated paper pulp. These products include but are not limited to paper, cartons, paper boxes, paper bags, paper cups, paper plates, paper towels, paper diapers, paper tableware, notebooks, paper printed materials, etc. Paper products are widely used in various fields such as packaging, printing, stationery, hygiene, catering, etc. due to their lightness, portability, recyclability and environmental protection.

[0003] The main raw materials for paper products are cellulose fibers, such as wood, waste paper, etc. In the pulping process, these raw materials are crushed, ground and mixed into pulp, and then the pulp is pressed into paper or other paper products through a series of papermaking machines. The quality of paper products depends on factors such as the quality of the pulp, processing technology and equipment.

[0004] At present, packaging paper products are widely used. Packaging paper molding is an important link in paper product production. Its main purpose is to process flat paper through certain processes to form paper products with specific shapes and structures. The core steps of packaging paper molding are: put pulp or paperboard into the molding mold, and form it into the desired shape and structure by pressing, squeezing or stretching. Then, the formed paper product is dried and shaped to remove excess moisture and fix the shape. After drying and shaping, the paper product can be further processed and assembled, such as cutting, folding, pasting, etc., to obtain the final desired paper product.

[0005] Based on this, Chinese patent CN109093719B discloses a cutting device for processing packaging cardboard, which includes a bottom plate, a supporting frame is fixedly installed on the bottom plate, an L-shaped supporting plate is fixedly installed in the supporting frame, a paper feed port is opened on the side wall of the supporting frame, a guide roller and a driving roller are rotatably provided on the L-shaped supporting plate, a blade is fixedly installed on one end of the cutting plate away from the supporting rotating plate, and a limiting sleeve slidably connected to the waist-shaped hole is sleeved on the transmission pin shaft; the cutting device for processing packaging cardboard is not only efficient in cutting the cardboard, but also ensures the smooth rightward movement of the cardboard through the limiting effect of the limiting roller and the guide roller, avoiding the occurrence of vertical position deviation, and the cardboard is fed to the right with equal length and cut by the blade, ensuring that the cardboard is cut evenly with equal length, ensuring the cutting quality of the cardboard, and the support block provided corresponds to the blade, plays a supporting role for the cardboard, and ensures the stable cutting of the cardboard.

[0006] However, the above disclosed cutting device for packaging cardboard processing still has the technical problem of low loading efficiency. Specifically, when the user uses the cutting device, cardboard loading is an important link in the process of paper product forming, which involves a series of operations such as carrying, positioning, clamping and feeding the cardboard into the production equipment. The goal of this process is to ensure that the cardboard can enter the production equipment accurately for subsequent cutting, printing, forming and other processes. Cardboard is usually large in size and may be heavy; therefore, it is necessary to use appropriate handling tools and equipment, such as forklifts, cranes or conveyor belts, to carry the cardboard from the storage area to the loading area. That is, currently the mainstream loading method is to load the cardboard by manpower, but in the process of carrying and loading the cardboard, it is necessary to ensure that the cardboard is stable and will not fall off; otherwise, it is easy to avoid causing personal injury or equipment damage. Moreover, the cardboard to be cut and processed usually has a sharp edge, and workers are prone to cut their palms during the process of carrying and loading. Utility Model Content
