Abstract

[0002] With the development of the economy and the improvement of people's living standards, plastic products are increasingly used in packaging, construction, automobiles, electronic appliances and other fields, and market demand continues to grow. In order to meet the rapid growth of market demand, plastic processing companies need to continuously improve production efficiency and reduce production costs. The plastic extruder heats the plastic to make it viscous and molten. Under pressure, it is injected into the extruder through the feed pipe, passing through a die with a certain shape to become a continuum with a cross-section similar to the die structure. Then, through cooling, it becomes a plastic product with a certain shape and size.
[0003] In the traditional plastic extruder feeding process, the material box is often filled with plastic materials for the sake of work efficiency, which is very easy to cause blockage of the material port or agglomeration. These problems are particularly prominent in large-scale production.

For this purpose, we propose an automatic feeding mechanism for the plastic extruder. Utility Model Content

[0038] Working principle: First, the plastic raw materials are placed in the material box 16 of the storage device 5. When the slow motor 17 is started, the drive shaft 18 rotates. The shaft 18 drives the reciprocating shaft 21 to reciprocate under the constraints of the support arm 19 and the second support arm 20 through the connecting block 22 and the movable sleeve 23. The swing column 24 on the reciprocating shaft 21 swings up and down in the material box 16 to achieve preliminary stirring and loosening of the raw materials, which is helpful for subsequent loading. The feeding port 25 at the bottom of the material box 16 is connected to the top of the feeding box 6. The stirred raw materials enter the feeding box 6 through the feeding port 25. The raw materials entering the feeding box 6 are rotated and conveyed by the motor 8 to drive the spiral roller 9. The rotation of the spiral roller 9 generates a forward propulsion force, which pushes the raw materials forward along the inside of the feeding box 6. Conveying, the feed box 6 is designed to be at an angle of 110 degrees to the loading barrel 10, which facilitates the smooth transition of raw materials to the loading barrel 10. In the process of the spiral roller 9 transmitting the raw materials to the loading barrel 10, the power is transmitted to the second spiral roller 14 through the universal joint 11, the connecting shaft 12 and the second universal joint 13. The two spiral rollers work together to ensure that the raw materials continue to be effectively pushed in the loading barrel 10. The rotation of the second spiral roller 14 pushes the raw materials to the discharge barrel 15, and finally outputs them to the target position (such as the feed port of the extruder) through the discharge barrel 15. The entire loading mechanism is fixed to the ground by a support plate 1 and is equipped with a universal wheel set 2 to facilitate the movement of the mechanism between different positions. A push handle 26 is also provided on the support plate 1 to facilitate manual movement or adjustment by the operator.
