Circulating feeding hopper type drying machine used for injection molding

Abstract

The invention discloses a circulating feeding hopper type drying machine used for injection molding. The circulating feeding hopper type drying machine comprises a top cover, a shell body, a lower cover, a first material kettle, a second material kettle, a bottom plate, a first spring, second springs, a connecting plate, a feeding pipe, a fan, a first air inlet pipe and a second air inlet pipe; the top cover is fixed on the upper part of the shell body, the lower cover is fixedly connected to the lower part of the shell body, the inner wall of the shell body is provided with two sets of bosses, the first material kettle and the second material kettle are correspondingly supported in the shell body through the first boss and the second boss, the bottom plate is located under the first material kettle, the first spring is connected with the top cover and the bottom plate, the second springs are connected with one end of the bottom plate and the connecting plate, the other end of the connecting plate is hinged with the second material kettle, the feeding pipe communicates with the inner part of the shell body through the top cover, the fan communicates with the inner part of the shellbody through an air pipe, and the air pipe is provided with two branches which are provided with air inlet valves. The circulating feeding hopper type drying machine used for injection molding can circularly feed and dry materials, and supply materials to a injection molding machine without intermittence, so that the working efficiency is improved and the working intensity is reduced.

Description

technical field [0001] The invention belongs to the technical field of injection molding machine equipment, and in particular relates to a hopper-type injection molding drier with circular feeding. Background technique [0002] Injection molding machine is the main molding equipment for making plastics into various shapes of plastic products using molding molds. It is also called injection molding machine or injection machine. Before the injection molding machine is injected, the raw material plastic particles need to be dried to match the molding of injection molding. To prevent the negative impact of moisture in raw material particles on injection molding products, with the development of plastic production technology, direct hot air hopper dryers are often used to dry plastic particles, because this type of injection molding dryer can be directly connected to the molding machine.

[0002] Injection molding machine is the main molding equipment for making plastics into various shapes of plastic products using molding molds. It is also called injection molding machine or injection machine. Before the injection molding machine is injected, the raw material plastic particles need to be dried to match the molding of injection molding. To prevent the negative impact of moisture in raw material particles on injection molding products, with the development of plastic production technology, direct hot air hopper dryers are often used to dry plastic particles, because this type of injection molding dryer can be directly connected to the molding machine. Direct blanking, increasing the injection rate, has the advantages of simplifying the work and saving manpower. The traditional hopper dryer needs to dry the material in advance before starting a drying cycle for injection molding. After the material in a hopper is injected, the injection molding is stopped and the material is baked again. Usually a drying cycle takes 2-4 hours or even longer, which wastes a lot of time. In order to make the injection molding time longer, the manufacturer needs to purchase a dryer with a larger capacity, which costs a lot of equipment and occupies a large area. The material is difficult to dry completely
