Description

A plastic extruder with good mixing effect

Technical Field

The utility model relates to the technical field of plastic extruders, in particular to a plastic extruder with good mixing effect.

Background Art

What is the product being written about? Plastic extruder is a plastic extrusion molding equipment. Plastic extruder is usually called the main machine, and the subsequent equipment plastic extrusion molding machine is called the auxiliary machine. Plastic extruder can be matched with various plastic molding auxiliary machines such as pipes, films, holding materials, monofilaments, flat wires, strapping tapes, extruded nets, plates, profiles, granulation, cable coating, etc. to form various plastic extrusion molding production lines and produce various plastic products.

The plastic extruder is composed of an extrusion system, a transmission system, and a heating and cooling system. The extrusion system includes a screw, a barrel, a hopper, a die, and a mold. The plastic is plasticized into a uniform melt through the extrusion system and is continuously extruded out of the die by the screw under the pressure established in the process. The material enters the barrel from the hopper and is then mixed, crushed, and transported under the action of the screw. However, the mixing effect of the screw is not ideal, which requires extending the time the material stays in the barrel, increasing the working time of the machine and reducing the working efficiency of the plastic extruder. At the same time, some dust will adhere to the outside of the material in the plastic warehouse. This dust will enter the barrel with the material, increase product impurities, and reduce production quality.

Implementation

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Please refer to Figures 1-3. The utility model provides a technical solution: the plastic extruder includes a screw, a barrel, a head, a mold and a hopper 1. The bottom of the hopper 1 is connected to the feed port of the barrel. A low-speed motor 3 is installed on the outside of the hopper 1. The output shaft of the low-speed motor 3 is connected to a stirring shaft 5. The stirring shaft 5 rotates with the operation of the low-speed motor 3. The stirring shaft 5 is a bucket-shaped structure, which can scoop up the material inside the hopper 1. At the same time, as the stirring shaft 5 rotates, the material falls from a high place inside the hopper 1, thereby achieving a mixing effect of the material, so that the material can be pre-mixed before entering the barrel, thereby reducing the time required for mixing the material in the barrel, thereby improving the production efficiency of the device, and through the mixing action of the stirring shaft 5, the problem of getting stuck at the outlet of the shell 2 can be avoided, thereby ensuring the smoothness of the feeding.

Please refer to Figures 1-4. A shell 2 connected to the outside of the hopper 1 is arranged above the low-speed motor 3. A driven gear 6 is arranged outside the shell 2. The driven gear 6 is movably installed outside the hopper 1, and the output shaft of the low-speed motor 3 is connected to the driving gear 4. The driving gear 4 and the driven gear 6 are in a meshing relationship, and the number of gears of the driving gear 4 is much larger than the number of gears of the driven gear 6. Therefore, the low-speed operation of the low-speed motor 3 can drive the fast rotation of the driven gear 6. The middle part of the driven gear 6 is connected to the fan blade 8, and the fan blade 8 is located inside the shell 2. The fan blade 8 is driven by the driven gear 6 to generate an airflow, which has an adsorption effect on the air inside the hopper 1, thereby making the inlet Dust outside the material entering the hopper 1 can enter the shell 2 with the airflow. At the same time, a filter screen 9 is movably inserted inside the shell 2 to filter the dust, thereby reducing the dust attached to the outside of the material, achieving the effect of reducing product impurities, and improving the production quality of the plastic extruder. At the same time, a mesh plate 7 is connected to one side of the shell 2 located inside the hopper 1. The mesh of the mesh plate 7 is smaller than the specification of the material, which can prevent the material from entering the shell 2 and facilitate the inhalation of dust. At the same time, the filter screen 9 is an inverted "concave" structure, which can facilitate the operation of the fan blades 8, and by movably inserting the filter screen 9, the filter screen 9 can be easily cleaned, thereby ensuring the normal operation of the device.

In summary, when the plastic extruder with good mixing effect is used, the plastic extruder is installed, the power supply is connected, the relevant parameters are set through the controller, the machine is started, the screw starts to rotate under the drive, the corresponding heating device on the barrel also starts to work, the low-speed motor 3 starts to work and drives the stirring shaft 5 to rotate, and at the same time the driving gear 4 drives the driven gear 6 to rotate, the driven gear 6 drives the fan blade 8 to rotate and generate airflow, so that the airflow inside the hopper 1 flows through the mesh plate 7, and the material is poured into the hopper 1. The dust attached to the outside of the material passes through the mesh plate 7 with the airflow and is filtered by the filter 9. After the material enters the bottom of the hopper 1, it falls from a high place with the rotation of the stirring shaft 5 to complete the mixing. At the same time, the material enters the barrel from the outlet at the bottom of the shell 2, and reaches the melting and molding parts after the transportation and shearing of the screw. It is discharged from the machine outlet after extrusion molding, and the filter 9 is regularly pulled out of the shell 2 and cleaned.
