Description

Technical Field

[0001] The utility model relates to the technical field of the production of POS machine casings, and particularly relates to an anti-blocking material feeding hopper for an injection molding machine. Background Art

[0002] POS (Point of sales) means "point of sale" in Chinese, and is fully called a point of sale information management system. It is a terminal reader equipped with bar code or OCR code technology and has the function of cash or barter quota cashier. Its main task is to provide data services and management functions for commodity and media transactions and conduct non-cash settlement. A POS is a multi-functional terminal. When it is installed in a special merchant of a credit card and an acceptance network and connected to a computer to form a network, it can realize automatic electronic fund transfer. It supports functions such as consumption, pre-authorization, balance inquiry, and transfer, and is safe, fast, and reliable to use. It is difficult to obtain basic business information in large transactions. Importing a POS system mainly solves the information management blind spot in the retail industry. It is an important part of the chain branch management information system. Currently, most POS machine casings are injection molded by an injection molding machine. An injection molding machine is also called an injection molding machine or an injection machine. It is the main molding equipment for making various shaped plastic products from thermoplastic or thermosetting plastics using plastic molding dies. It is divided into vertical, horizontal, and all-electric types. An injection molding machine can heat plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity. When injection molding, generally, plastic raw materials enter the mold of the injection molding machine through a feeding hopper.

[0003] For example, the anti-blocking injection molding machine disclosed in the publication (announcement) number CN208681966U includes an injection molding machine body. An injection hopper is provided on the injection molding machine body. Clamping plates are fixedly installed on both sides of the injection hopper. Upper plates are fixedly installed on the sides of the two clamping plates away from each other. Two support rods are fixedly installed on the sides of the two upper plates away from each other. The bottom ends of the two support rods are fixedly installed on the top of the injection molding machine body. A motor is provided at the bottom of the upper plate on one side of the injection hopper. A first bevel gear is fixedly installed on the output shaft of the motor. First through holes are opened on both sides of the injection hopper. A first round rod is rotatably installed in the first through hole.

[0004] Although the above technical solution solves the corresponding technical problems, the above technical solution still has the following defects:

[0005] The above technical solution realizes the dredging of the injection plastic by the rotation of the stirring blades. It is found in the actual use process that its dredging effect is not good and it is still easy to block the material.

[0006] Therefore, an anti-blocking material feeding hopper for an injection molding machine is proposed. Content of the Utility Model
