Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of plastic processing equipment, specifically relating to a plastic modifier addition device. Background Technology
[0002] In the plastics processing, various modifiers, such as toughening agents, flame retardants, and antioxidants, are usually added to improve the properties of plastics. Traditional methods of adding modifiers mainly include manual and mechanical addition.
[0003] The manual addition method has the following problems:
[0004] Low precision: Manual addition makes it difficult to accurately control the amount added, which can easily lead to unstable product quality.
[0005] Low efficiency: Manual addition is slow and cannot meet the needs of large-scale production.
[0006] High labor intensity: Manual addition requires a large amount of manpower and is labor-intensive.
[0007] While mechanical addition has solved the problem of manual addition to some extent, it still has the following shortcomings:
[0008] Uneven mixing: Traditional mechanical additive devices are difficult to achieve full mixing of modified materials and plastics, and are prone to agglomeration or uneven dispersion. This is mainly because the mixing device usually contains a large amount of raw materials and its stirring shaft is relatively large, while the content of modified materials is relatively low compared to the raw materials. It is difficult to fully disperse in such a mixing device. In addition, some modified materials are prone to agglomeration, which makes dispersion even more difficult. Utility Model Content
[0009] To address the aforementioned technical problems, this utility model provides a plastic modifier addition device to solve the problem of uneven dispersion in existing plastic modifier addition methods. This plastic modifier addition device can effectively promote the dispersion of modifiers and prevent material agglomeration.
[0010] This utility model discloses a plastic modifier addition device, including a mixing chamber, a top cover, a first motor, a first stirring shaft, a premix tank, a feed pipe, a discharge pipe, a second motor, a second stirring shaft, and a modifier supply device. The top cover is located on top of the mixing chamber, the first motor is located on top of the top cover, the first stirring shaft is located in the mixing chamber and the top of the first stirring shaft is connected to the first motor, the top side wall of the premix tank is connected to the side wall of the mixing chamber through the discharge pipe, the bottom side wall of the premix tank is connected to the side wall of the mixing chamber through the feed pipe, a circulation pump is provided on the feed pipe, the second motor is located on top of the premix tank, the second stirring shaft is located in the premix tank and the top of the second stirring shaft is connected to the second motor, and the modifier supply device is connected to the premix tank.
[0011] Furthermore, the top cover is provided with a feed inlet, the bottom of the mixing chamber is provided with a discharge outlet, and the discharge outlet is provided with a discharge valve.
[0012] Furthermore, it also includes a heating jacket, which is fitted inside the mixing chamber.
[0013] When adding modifiers, this plastic modifier adding device can pre-place the plastic raw material in the mixing chamber and heat it to melt. Then, a small amount of plastic raw material is introduced into the premixing tank through the feed pipe. The modifier feeding device then feeds the modifier into the premixing tank. Since the volume of the premixing tank is much smaller than that of the mixing chamber, the second stirring shaft can promote the pre-mixing of the modifier and the plastic raw material. The premixed mixture is then fed into the mixing chamber through the discharge pipe. Due to the affinity between the mixture and the plastic raw material, the dispersion of the modifier in the mixing chamber can be effectively promoted, and the agglomeration of the modifier can be avoided, thus improving the mixing uniformity of the modifier.
