Description

Technical Field

[0001] The utility model relates to the technical field of plastic powder processing, in particular to a horizontal mixer for plastic powder. Background Art

[0002] In the field of plastic powder processing, the mixing process is crucial to ensure product quality and production efficiency. However, traditional plastic powder mixing equipment often faces a series of challenges in practical applications, which limit its application in efficient and high-quality production.

[0003] First, uneven mixing has long been a problem that has plagued the plastic powder processing industry. Due to differences in the physical properties of plastic powders, such as particle size, shape, density and surface properties, traditional mixing equipment often has difficulty achieving uniform dispersion of materials during the mixing process. This unevenness not only leads to unstable product performance, but may also cause quality problems such as color difference and uneven strength due to local overheating or insufficient mixing. In particular, when dealing with plastic powders with special properties, such as high viscosity, easy to agglomerate or materials with electrostatic effects, the limitations of traditional mixing equipment are more prominent.

[0004] Secondly, the dead corners of mixing are another key factor that affects the mixing effect. Due to the shape design of the mixing drum, the layout of the agitator or the limitations of the mixing method, traditional mixing equipment often has difficult-to-reach areas during the mixing process, namely the dead corners of mixing. The materials in these areas cannot be effectively mixed and dispersed, which reduces the overall mixing efficiency and may lead to inconsistent product quality. The existence of dead corners of mixing also increases the risk of material residue and puts higher requirements on the cleaning and maintenance of the equipment.

[0005] In addition, inconvenient discharging is also one of the common problems of traditional mixing equipment. Some mixing equipment requires manual assistance or complex discharging mechanisms when discharging, which not only increases the difficulty and labor intensity of operation, but may also cause material loss or contamination due to improper operation. Inconvenient discharging also prolongs the production cycle, reduces production efficiency, and has an adverse impact on the company's production plan and cost control.

[0006] Finally, cleaning difficulties are an unavoidable problem in the long-term use of mixing equipment. Due to the adhesion and electrostatic effect of plastic powder, a large amount of material often remains inside the equipment after mixing. These residual materials are not only difficult to clean thoroughly, but may also contaminate the next mixed material, affecting product quality. At the same time, the cleaning work also increases the downtime and maintenance costs of the equipment, which has a negative impact on the production efficiency and economic benefits of the enterprise.

[0007] The purpose of the present utility model is to solve the drawbacks existing in the prior art, and a horizontal plastic powder mixer is proposed.

[0008] To achieve the above object, the present utility model adopts the following technical solution: a horizontal plastic powder mixer, comprising a mixing barrel, a first motor and a second motor. The first motor is fixedly connected to one side wall of the mixing barrel. An inlet is arranged on the upper surface of the end of the mixing barrel away from the first motor, and an outlet is arranged on the lower surface of the end of the mixing barrel away from the first motor. The driving end of the first motor is fixedly connected with a stirring rod, and a plurality of stirring blades are equidistantly arranged on the upper and lower surfaces of the stirring rod. One end of the stirring blade away from the stirring rod is fixedly connected with a fixing plate, and fixing blocks are fixedly connected to the front and rear surfaces of the fixing plate. One end of the stirring rod away from the first motor is fixedly connected with a material guiding plate, and the shape of the material guiding plate is a frustum of a cone, and the material guiding plate is in contact with the inner wall of the mixing barrel. Support plates are arranged on both the front and rear sides of the mixing barrel, and the second motor is fixedly connected to the outer surface of one of the support plates away from the mixing barrel. The driving end of the second motor is fixedly connected to the mixing barrel through a rotating shaft, and the mixing barrel is rotatably connected to the other support plate through a rotating shaft.

[0009] Preferably, the material guiding plate is located directly below the inlet.

[0010] Preferably, the outer surfaces of the fixing plate and the fixing block away from the stirring rod are in contact with the inner wall of the mixing barrel. The outer surface of the fixing block away from the stirring blade is an arc surface, and the outer surface of the fixing block away from the fixing plate is an inclined surface.

[0011] Preferably, a cleaning plate is fixedly connected to the inner wall of the mixing barrel away from the first motor, and the cleaning plate is in contact with the inclined surface of the material guiding plate.

[0012] The present utility model has the following beneficial effects:

[0013] 1. For this horizontal plastic powder mixer, the first motor can drive the material guiding plate on the driving rod to rotate, so that the material guiding plate can disperse the material entering the mixing barrel from the inlet, thereby making the material in the mixing barrel evenly dispersed, which is convenient for improving the mixing effect of the material in the mixing barrel. Moreover, the second motor can drive the mixing barrel to rotate and tilt, so that the end of the mixing barrel away from the inlet rotates and tilts downward, so that the material dispersed by the material guiding plate can be evenly dispersed on the inner bottom wall of the mixing barrel.

[0014] 2. The horizontal plastic powder mixer can drive the mixing drum to swing reciprocally through the second motor, enabling the materials in the mixing drum to roll along the inner wall of the mixing drum, preventing the accumulation of materials in the mixing drum, thus making the mixing effect of the mixing blades on the materials in the mixing drum better. Moreover, the second motor can drive the discharge port on the mixing drum to rotate downward for cleaning, allowing the materials in the mixing drum to roll along the inner wall of the mixing drum to the discharge port, facilitating the discharge of the materials from the discharge port out of the mixing drum.

[0015] 3. The horizontal plastic powder mixer can drive the mixing blades to drive the fixed plate to rotate through the first motor, enabling the fixing blocks on the fixed plate to lift the materials on the inner bottom wall of the mixing drum, thereby avoiding the deposition of materials on the inner bottom wall of the mixing drum. Moreover, when the cleaning plate contacts the material distribution plate, during the rotation of the material distribution plate, the cleaning plate can clean the inclined surface of the material distribution plate to prevent material residue on the material distribution plate.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0020] Such as Figure 1-2As shown in the figure, an embodiment of the present utility model provides a horizontal plastic powder mixer, which includes a mixing cylinder 1, a first motor 4, and a second motor 11. The first motor 4 is fixedly connected to one side wall of the mixing cylinder 1. An inlet 2 is provided on the upper surface of the end of the mixing cylinder 1 far from the first motor 4, and an outlet 3 is provided on the lower surface of the end of the mixing cylinder 1 far from the first motor 4. The driving end of the first motor 4 is fixedly connected to a stirring rod 5. A plurality of stirring blades 6 are equidistantly arranged on the upper and lower surfaces of the stirring rod 5. One end of the stirring blade 6 far from the stirring rod 5 is fixedly connected to a fixing plate 7. Fixing blocks 8 are fixedly connected to the front and rear surfaces of the fixing plate 7. One end of the stirring rod 5 far from the first motor 4 is fixedly connected to a material guiding plate 9. The shape of the material guiding plate 9 is a frustum of a cone, and the material guiding plate 9 is in contact with the inner wall of the mixing cylinder 1. Support plates 12 are arranged on both the front and rear sides of the mixing cylinder 1. The second motor 11 is fixedly connected to the outer surface of one of the support plates 12 far from the mixing cylinder 1. The driving end of the second motor 11 is fixedly connected to the mixing cylinder 1 through a rotating shaft, and the mixing cylinder 1 is rotatably connected to the other support plate 12 through a rotating shaft.

[0021] The material guiding plate 9 is located directly below the inlet 2. This design ensures that the plastic powder entering from the inlet 2 can directly fall on the material guiding plate 9, and the material guiding plate 9 conducts preliminary dispersion and guidance. The rotation of the material guiding plate 9 can further evenly disperse the material to various areas of the mixing cylinder 1, avoiding the accumulation and caking of the material near the inlet 2, and improving the uniformity and efficiency of mixing.

[0022] The outer surfaces of the fixing plate 7 and the fixing blocks 8 far from the stirring rod 5 are in contact with the inner wall of the mixing cylinder 1. Such a design helps to lift the materials on the inner bottom wall and side wall of the mixing cylinder 1 during the stirring process, preventing the materials from depositing. At the same time, the arc surface design of the fixing blocks 8 enables it to better fit the inner wall of the mixing cylinder 1, reducing the accumulation of materials at the bottom. The outer surface of the fixing block 8 far from the fixing plate 7 is an inclined surface. This design enables the fixing block 8 to more easily push the materials towards the center or a higher position of the mixing cylinder 1 during the stirring process, further promoting the mixing and dispersion of the materials.

[0023] A cleaning plate 10 is fixedly connected to the inner wall of the mixing cylinder 1 far from the first motor 4 and is in contact with the inclined surface of the material guiding plate 9. During the stirring process, as the material guiding plate 9 rotates, the cleaning plate 10 can automatically scrape the inclined surface of the material guiding plate 9, effectively removing the material residues attached thereto. This self-cleaning mechanism reduces the need for manual cleaning, improves the self-cleaning ability of the equipment, and ensures the continuity and stability of the stirring process.

[0024] Working principle: When using the horizontal plastic powder mixer, open the feeding port 2 and pour the plastic powder raw materials into the mixing drum 1. The raw materials will first fall on the guiding plate 9. The first motor 4 can drive the guiding plate 9 to rotate. The guiding plate 9 is located directly below the feeding port 2, and its rotation can effectively disperse the incoming materials evenly to various areas of the mixing drum 1, avoiding the accumulation and caking of materials in the initial stage of mixing. With the operation of the first motor 4, the stirring rod 5 drives the stirring blades 6 and the fixing plate 7 to rotate. The stirring blades 6 strongly stir and turn the materials in the mixing drum 1, causing the materials to form complex convection and shear movements in the mixing drum 1. The design of the fixing plate 7 and the fixing block 8 helps to lift the materials on the inner bottom wall and side wall of the mixing drum 1, preventing material deposition, and working together with the stirring blades 6 to promote the full mixing of the materials. During this process, the differences in particle size, density, etc. of the materials gradually decrease under the stirring action and finally achieve the effect of uniform mixing. During the process of the stirring blades 6 stirring the materials, the second motor 11 drives the mixing drum 1 to perform reciprocating tilting oscillations. This dynamic tilting helps the materials to more fully cover the inner bottom wall of the mixing drum 1, reducing the mixing dead zones and achieving the full mixing of the materials. The reciprocating oscillation of the mixing drum 1 can also cause the materials to roll in the drum, further preventing the accumulation and stratification of the materials and improving the mixing quality. After mixing is completed, by adjusting the tilting angle of the mixing drum 1, the discharge port 3 on the mixing drum 1 is rotated and tilted downward, and then the discharge port 3 is opened, and the materials can naturally roll to the discharge port 3 and be discharged smoothly. During the mixing process, with the rotation of the guiding plate 9, the cleaning plate 10 can automatically scrape the inclined surface of the guiding plate 9, effectively removing the material residues attached thereto. This self-cleaning mechanism reduces the need for manual cleaning, improves the self-cleaning ability of the equipment, and ensures the continuity and stability of the mixing process.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made therein without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
