Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of paper cup production equipment, and in particular to the feeding structure of disposable paper cup forming equipment. Background Technology
[0002] Disposable paper cups are widely used in homes, public places, restaurants, hospitals, and other locations due to their convenience, low price, and safety and hygiene. As people's living standards improve, the demand for disposable paper cups continues to increase, which in turn drives the development of paper cup forming equipment.
[0003] Paper pulp, typically made from wood fibers, is the core material for producing disposable paper cups. During production, a fixed amount of pulp is injected into a molding cavity and formed through adsorption. However, before the pulp is fed into the mold for forming, impurities and particles must be broken down to ensure the produced paper cups meet production requirements. Existing disposable paper cup forming equipment lacks this crucial step in its feeding structure, resulting in incomplete removal of impurities. This affects the quality and performance of the paper cups, reducing their strength, water resistance, and hygiene standards. Utility Model Content
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. The purpose of the present invention is to provide a feeding structure for a disposable paper cup forming equipment to solve the problems mentioned in the background art.
[0005] To address the aforementioned problems, this utility model provides a feeding structure for a disposable paper cup forming equipment, comprising a feeding box and a conveyor. The feeding box has a feeding port at its top, and a guide hopper is inserted into the feeding port. A mounting frame is provided on the inner side wall of the feeding box, and a stirring assembly is mounted on the mounting frame. A discharge port is provided on the side of the feeding box near the conveyor. A conveyor belt is mounted on the conveyor, and a limit frame is mounted directly above the conveyor belt. A lower pressure roller is provided on the limit frame.
[0006] The feeding structure of the disposable paper cup forming equipment provided by this utility model also has the following technical features:
[0007] Furthermore, a servo motor is installed on the side of the feed box, and the output end of the servo motor passes through the mounting frame and is connected to the stirring assembly.
[0008] Furthermore, the stirring assembly includes stirring rods, connecting sleeves, and protrusions / concaves. There are two stirring rods, which are connected and fixed together by the connecting sleeve. The connecting sleeve is fixedly connected to the output shaft of the servo motor, and the protrusions / concaves are evenly fixedly connected to the stirring rods.
[0009] Furthermore, the limiting frame has positioning holes, and the two ends of the lower pressure roller are movably connected to rotating rods. The lower pressure roller is connected to the positioning holes of the limiting frame through the rotating rods.
[0010] Furthermore, the upper edge of the feed inlet is provided with an inclined slot, and the two sides of the front end of the guide hopper are fixedly connected with locking blocks. The guide hopper is fixedly engaged with the inclined slot of the feed inlet by the locking blocks.
[0011] Furthermore, a drive motor is provided on the side of the conveyor, and the drive motor is connected to the power input end of the conveyor belt.
[0012] Furthermore, a buffer plate is provided below the discharge port, and the buffer plate corresponds to the starting end of the conveyor belt.
[0013] Furthermore, an observation window is installed on the side of the feed box.
[0014] This invention has the following beneficial effects: First, the pulp is poured into the guide hopper and flows into the feed box. Then, the servo motor is started, and the output shaft of the servo motor drives the stirring assembly to rotate. The stirring assembly includes two stirring rods, on which unevenly arranged bumps and dents are provided. These bumps and dents fully stir the pulp during the stirring process, effectively breaking down and dispersing impurities and particles in the pulp, thereby improving the purity of the pulp. At the same time, it ensures that the pulp has good fluidity and uniformity, providing a high-quality raw material basis for the subsequent molding process. Second, the stirred pulp flows into the starting end of the conveyor belt through the discharge port on the side of the feed box. The drive motor of the conveyor is started, and the conveyor belt starts running, smoothly conveying the pulp to the molding cavity. On the conveyor belt, the lower pressure roller is installed directly above the conveyor through the positioning hole of the limit frame. The lower pressure roller flattens and straightens the pulp on the conveyor belt, ensuring that the pulp is evenly distributed on the conveyor belt and preventing pulp accumulation or overflow. This uniform distribution not only helps improve the forming quality of the pulp, but also avoids equipment failures and paper cup quality defects caused by uneven pulp distribution.
