Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material mixing and stirring equipment, in particular to a material mixing device for an injection molding machine. Background Technique
[0002] The material mixing device for an injection molding machine is a mechanical device specifically used for mixing and stirring different types or colors of plastic raw materials. Through specific stirring methods and processes, the plastic raw materials can achieve a uniform mixing effect to meet the requirements of subsequent processing or production. The working principle of the plastic material mixing and stirring device is mainly based on the rotational movement of the stirrer. When the motor is started, power is transmitted to the stirrer through the transmission device, causing it to rotate inside the stirring barrel or the housing. The design of the stirring barrel or the housing also takes into account the fluidity and mixing uniformity of the materials to ensure the best mixing effect.
[0003] The following defects still exist in the prior art during use:
[0004] 1. During the feeding process of the injection molding materials in the prior art, they will directly fall into the stirring box body, resulting in a large part of the materials that are too large to be directly stirred also falling into the stirring cavity, thus making it impossible to achieve smooth stirring.
[0005] 2. During the stirring process of the injection molding materials in the prior art, the stirring blades are easily blocked by the plastic materials, and there may be a situation where smooth stirring cannot be achieved. If the blockage of the stirring blades cannot be quickly detected, it may cause the subsequent failure of the stirring device to work smoothly.
[0006] In view of this, we propose a material mixing device for an injection molding machine to solve the existing problems. Content of the Utility Model

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] 1. By providing a vibrating screening bin at the feeding port, the plastic materials can be screened to a certain extent through the vibrating screening bin. By screening the plastic materials, some materials that are not easy to be stirred and mixed can be screened out, which can make the overall stirring of the stirring materials entering the stirring cavity more efficient.
