Description

Technical Field

[0001] This utility model relates to a plastic processing equipment, and more specifically, to a plastic processing mixing device. Background Technology

[0002] A plastic processing mixing unit is a device specifically designed for the plastics industry to uniformly mix plastic granules, powders, and various additives. This device is crucial for ensuring the quality of plastic products because it guarantees that all raw material components are fully and uniformly dispersed before plastic molding (processes such as extrusion, injection molding, or blow molding).

[0003] When existing plastic processing mixing equipment is in use, due to the significant differences in physical and chemical properties between different types of plastic particles, powders or additives, such as density, particle size, shape, surface characteristics and flowability, these differences cause some components to tend to aggregate rather than be evenly distributed throughout the mixture. This results in uneven mixing of plastic raw materials, which leads to unstable quality of the final plastic products and reduces product quality.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a plastic processing mixing device to solve the technical problem of uneven mixing of plastic raw materials.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a plastic processing mixing device, comprising an upper mixing drum and a lower mixing drum, wherein a support column is fixedly installed on the opposite surfaces of the upper and lower mixing drums, and the upper and lower mixing drums are connected by a connecting pipe, a feed hopper is fixedly installed on the upper left side of the upper mixing drum, a first motor is fixedly installed on the top of the upper mixing drum, a first agitator is fixedly installed on the output end of the first motor, a second motor is fixedly installed on the bottom of the lower mixing drum, a second agitator is fixedly installed on the output end of the second motor, the first agitator and the second agitator are respectively located inside the upper and lower mixing drums, and a discharge pipe is fixedly installed on the bottom of the lower mixing drum.

[0007] The present invention is further configured such that both the connecting pipe and the discharge pipe are equipped with a solenoid valve.

[0008] The present invention is further configured such that four support legs are fixedly installed at the lower end of the lower stirring cylinder.

[0009] The present invention is further configured such that the centerlines of the first stirrer and the second stirrer coincide.

[0010] In summary, this utility model has the following beneficial effects:

[0011] The first motor drives the first agitator to rotate clockwise, while the second motor starts and drives the second agitator to rotate counterclockwise. The agitator is set up with an upper and lower mixing drum, forming a double-layer mixing structure. By using different rotation directions (such as clockwise for the upper layer and counterclockwise for the lower layer), the relative motion between materials can be significantly increased. This not only helps to break up the material stratification caused by differences in density or particle size, but also effectively reduces "dead zones," that is, areas that are difficult to reach by traditional unidirectional mixing. This ensures that all materials undergo similar shearing, stretching, and folding processes, thereby achieving more uniform mixing and improving the quality of raw material processing.

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] A plastic processing mixing device, such as Figures 1 to 2 As shown, the apparatus includes an upper mixing drum 1 and a lower mixing drum 2. Support columns 3 are fixedly installed on the opposite surfaces of the upper mixing drum 1 and the lower mixing drum 2. A connecting pipe 4 connects the upper mixing drum 1 and the lower mixing drum 2. A feed hopper 5 is fixedly installed on the upper left side of the upper mixing drum 1. A first motor 6 is fixedly installed on the top of the upper mixing drum 1. A first agitator 7 is fixedly installed at the output end of the first motor 6. A second motor 8 is fixedly installed at the bottom of the lower mixing drum 2. A second agitator 9 is fixedly installed at the output end of the second motor 8. The first agitator 7 and the second agitator 9 are located inside the upper mixing drum 1 and the lower mixing drum 2, respectively. A discharge pipe 10 is fixedly installed at the bottom of the lower mixing drum 2.

[0020] like Figure 1 As shown, both the connecting pipe 4 and the discharge pipe 10 are equipped with a solenoid valve 11. By opening and closing the solenoid valve 11, the timing and flow rate of material transfer from the upper mixing drum 1 to the lower mixing drum 2 are controlled. When the material in the upper mixing drum 1 has completed the initial mixing, the solenoid valve 11 opens, and the material enters the lower mixing drum 2 through the connecting pipe 4 for further mixing. This process ensures the continuity and uniformity of the mixing process. The solenoid valve 11 precisely controls the discharge of the mixed material. When the material has been fully mixed in the lower mixing drum 2, the solenoid valve 11 opens, and the uniformly mixed material is discharged from the discharge pipe 10. This process avoids the accumulation of material in the device or premature discharge, thus ensuring product quality.

[0021] like Figure 1 As shown, four support legs 12 are fixedly installed at the lower end of the lower mixing drum 2 to support the entire mixing device and improve the stability of the overall equipment.

[0022] The centerlines of the first agitator 7 and the second agitator 9 coincide. The first agitator 7 performs preliminary mixing of the materials in the upper mixing drum 1, while the second agitator 9 further mixes the materials in the lower mixing drum 2. Because the centerlines coincide, the flow of materials between the upper and lower mixing drums is more uniform, thereby improving the overall mixing uniformity.

[0023] Working principle: Material input: First, plastic granules, powder or additives enter the upper mixing drum 1 through the feed hopper 5.

[0024] Preliminary mixing stage: The first motor 6 and the second motor 8 are electrically connected to an external power supply through an external control switch group. The first motor 6 drives the first agitator 7 to rotate clockwise to perform preliminary mixing of the material in the upper mixing drum 1. The agitator rod produces shearing, squeezing and tumbling effects on the material, so that the material is initially mixed and dispersed. After the preliminary mixing is completed, the solenoid valve 11 in the connecting pipe 4 opens under the action of gravity and the agitator, and the material enters the lower mixing drum 2 through the connecting pipe 4.

[0025] Further mixing stage: Inside the lower mixing drum 2, the second motor 8 starts, driving the second agitator 9 to rotate counterclockwise. This rotation direction is opposite to that of the first agitator 7, further mixing and uniformly dispersing the materials. The upper and lower drum design allows for improved mixing uniformity by using different stirring speeds or directions (such as clockwise for the upper layer and counterclockwise for the lower layer). Different stirring directions help break up any new agglomerations that may form during the stirring process, allowing the materials to disperse more fully. The clockwise and counterclockwise stirring directions generate shear forces between the materials, which help break the materials into smaller particles, thereby improving the uniformity of mixing.

[0026] Once the mixture is homogeneous, the solenoid valve 11 inside the discharge pipe 10 opens, and the homogeneous material is discharged from the discharge pipe 10.

[0027] In summary, by setting up a double-layer stirring structure and adopting different rotation directions (such as clockwise for the upper layer and counterclockwise for the lower layer), the relative motion between materials can be significantly increased. This not only helps to break the material stratification phenomenon caused by differences in density or particle size, but also effectively reduces "dead zones," that is, areas that are difficult to reach by traditional unidirectional stirring, ensuring that all materials can undergo similar shearing, stretching, and folding processes, thereby achieving a more uniform mixing.

[0028] It is worth noting that the first motor 6 and the second motor 8 disclosed in the above embodiments are specifically models of Panasonic MINAS A6 series, and the operation of the first motor 6 and the second motor 8 by the external control switch group and the external power supply adopts the methods commonly used in the prior art.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
