Description

Technical Field

[0001] The utility model relates to the technical field of mixing and drying devices, in particular to a raw material mixing and drying device for an injection molding machine. Background Art

[0002] Injection molding machines are used to make plastic wine boxes. Injection molding machines can produce a variety of plastic products, including plastic boxes made of plastics such as polypropylene or polyethylene. In the production process, plastic particles are first heated and melted, and then injected into the mold through the injection molding machine. After a certain pressure and temperature, the plastic cools and solidifies in the mold to form the desired box shape. After that, it is cooled, demolded, and post-processed such as trimming the edges, cutting off excess parts, etc., as well as possible printing and assembly steps to finally complete the production of plastic wine boxes. Therefore, injection molding machines play an important role in the production process of plastic wine boxes.

[0003] When injecting materials for making plastic boxes into an injection molding machine, multiple raw materials must first be mixed, and in order to prevent bubbles or defects in the plastic mixture during the injection molding process, the plastic mixture needs to be dried while mixing, so an injection molding machine raw material mixing and drying device is used, but most of the existing mixing devices install heat sources such as electric heating rods inside the device for dehumidification and drying. This method can only perform local drying, which is not uniform enough and can easily lead to bubbles in the produced plastic wine boxes, and the plastic raw materials close to the heat source are easily over-dry and do not meet the production standards. Therefore, in response to the above technical problems, an injection molding machine raw material mixing and drying device is proposed herein. Utility Model Content

[0013] The technical solution of the utility model has at least the following beneficial effects:

[0014] The utility model proposes a raw material mixing and drying device for an injection molding machine. By arranging an arc-shaped heat pipe at the bottom of a mixing barrel and installing the arc-shaped heat pipe very close to the mixing barrel, after stirring and mixing in the mixing barrel, the mixing barrel is driven to rotate as a whole by a No. 1 motor, so that the outer wall of the mixing barrel can be kept at a high temperature and the temperature distribution of the outer wall can be relatively uniform.
