Description

Technical Field

[0001] This application relates to the field of plastics processing, and more specifically, to a plasticizing apparatus for processing plastic raw materials. Background Technology

[0002] Currently, plastic masterbatch is a concentrated form made by loading plastic additives into resin in an excessive amount. When manufacturing plastic products, it is not necessary to add the plastic additives. Only this masterbatch with an excessive amount needs to be added in proportion. Therefore, plastic masterbatch is a new type of special material for processing polymer materials.

[0003] The surface of plastic masterbatch that has been stored for a long time is covered with dust and must be cleaned before use. After cleaning, the surface of the material is still wet and needs to be dried. Therefore, two machines are needed to perform two processes, which is time-consuming, labor-intensive and inefficient. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a plastic raw material processing and plasticizing device, which aims to improve the problem that the drying and plasticizing of plastic masterbatch requires two processes and is cumbersome to operate.

[0005] This application provides a plasticizing device for processing plastic raw materials, including a support frame, a material cylinder, and a plasticizing box;

[0006] The material cylinder is installed on the upper end of the support frame. The material cylinder is inclined and contains a auger with a built-in heating tube. The surface of the auger's spiral blades has filter holes. A water collection hopper is installed at the bottom of the lower end of the material cylinder, and an air wall emitter is installed at the upper end of the water collection hopper. The air wall emitter forms an air wall in the cross section inside the material cylinder to trap moisture on the surface of the material. The material cylinder is equipped with a driver to drive the auger to rotate.

[0007] The plasticizing box is located on the lower surface of the upper end of the material cylinder. The upper port of the plasticizing box is connected to the inner wall of the material cylinder. The plasticizing box is equipped with a heating wire, and the lower end of the plasticizing box is connected to a discharge port.

[0008] In a preferred embodiment of this utility model, the support frame includes a column and a hinge seat. The upper end of the column is hinged to the hinge seat. The hinge seat is fixed to the surface of the material cylinder. An annular limiting groove is formed on the surface of the hinge seat. A limiting bolt is threaded to the upper end of the column. The limiting bolt is engaged in the annular limiting groove. A base is fixed to the lower end of the column. An installation hole is formed on the surface of the base.

[0009] In a preferred embodiment of this utility model, the air wall emitter is connected to an air outlet pipe and an air exhaust pipe. The lower ends of the air outlet pipe and the air exhaust pipe are connected to the inside of the material cylinder. The air outlet pipe and the air exhaust pipe are arranged on both sides of the cross-section of the material cylinder.

[0010] In a preferred embodiment of this utility model, the air wall emitter is fixed to the surface of the material cylinder, and the air wall emitter is disposed between the water collection hopper and the plasticizing tank.

[0011] In a preferred embodiment of this utility model, the auger includes a hollow shaft and spiral blades. The spiral blades are fixed on the surface of the hollow shaft, and a heating tube is disposed inside the hollow shaft. One end of the heating tube is connected to the hollow shaft via an electric slip ring, and the gap between the outer wall of the hollow shaft and the inside of the barrel is no more than 5 cm.

[0012] In a preferred embodiment of this utility model, the driver is a geared motor, which is fixed to the upper end of the material cylinder. The drive shaft of the driver is connected to the upper end of the auger, and the lower end of the material cylinder is connected to a feed hopper.

[0013] In a preferred embodiment of this utility model, a gear is coaxially fixed to the drive shaft of the reduction motor, a gear plate is rotatably mounted on the upper end of the material cylinder, the gear plate is coaxially fixedly connected to the upper end of the auger, and the gear meshes with the gear plate.

[0014] In a preferred embodiment of this utility model, an observation window is embedded in the side wall of the material cylinder, and a drain pipe is connected to the lower end of the water collection hopper.

[0015] Beneficial Effects: This application provides a plasticizing device for processing plastic raw materials. A rotating auger pushes the material at the bottom of the cylinder to the plasticizing tank at the top. When the material passes through the airflow barrier formed by the air wall emitter, the surface moisture is trapped. The trapped water flows downward on the inclined inner wall of the cylinder. The filter holes facilitate the water flow, and the water eventually accumulates in the water collection hopper, achieving a drying effect. At the same time, a heating tube is built into the auger. By heating the auger, the spiral blades of the auger are kept at a high temperature, so that the spiral blades also dry the material while pushing it. It also has a preheating effect on the material, so that the material finally pushed to the plasticizing tank is dry and has a certain temperature, which is convenient for plasticizing treatment, reduces production costs, and improves processing efficiency.
