Description

Technical Field

[0001] This application relates to the field of plastic packaging materials technology, and in particular to a device for homogenizing the mixing of raw materials for plastic packaging materials. Background Technology

[0002] Plastic packaging materials are widely used in modern industry and daily life, and their quality and performance largely depend on the uniformity of the raw material mixing. Existing devices for mixing raw materials in plastic packaging materials have many shortcomings. Traditional mixing devices often simply stir the raw materials with a stirring paddle. However, the raw materials for plastic packaging materials typically include various components with different properties, such as plastic granules, additives, and color masterbatches. These raw materials differ in particle size, density, and flowability. Relying solely on conventional stirring methods makes it difficult to ensure that all raw materials are thoroughly and uniformly mixed in a short time. Furthermore, denser additive particles may gradually settle to the bottom of the device during stirring, leading to uneven mixing and affecting the quality of the final plastic packaging material, causing defects in its physical properties and appearance. Therefore, a device for homogenizing the mixing of raw materials for plastic packaging materials is proposed to solve the above problems.

[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0004] To address the aforementioned problems, this application provides a device for homogenizing the mixing of raw materials for plastic packaging materials.

[0006] A plastic packaging material raw material mixing and homogenization device includes a frame, a mixing chamber fixedly connected to the outer wall of the frame, two inlets on the outer wall of the mixing chamber, a main shaft rotatably connected to the inner wall of the mixing chamber, two connecting rods fixedly connected to the outer wall of the main shaft in a linear array symmetrically, two stirring paddles fixedly connected to the outer walls of the two connecting rods, and the two stirring paddles are designed to cross each other, and a feeding assembly is provided on the bottom outer wall of the mixing chamber.

[0007] Preferably, a protective plate is rotatably connected to the outer side wall of the mixing chamber, and a snap-fit ​​assembly is provided between the protective plate and the mixing chamber.

[0008] Preferably, the feeding assembly includes a feeding port, which is fixedly connected to the bottom of the mixing chamber.

[0017] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0018] Example 1:

[0019] A plastic packaging material raw material mixing and homogenization device includes a frame 1. A mixing chamber 5 is fixedly connected to the outer wall of the frame 1. Two inlets 2 are opened on the outer wall of the mixing chamber 5 to facilitate the pouring of plastic packaging material raw materials, thereby facilitating mixing in the mixing chamber 5. A main shaft 13 is rotatably connected to the inner wall of the mixing chamber 5. Two connecting rods 14 are fixedly connected to the outer wall of the main shaft 13 in a linear array symmetrically. Two stirring paddles 15 are fixedly connected to the outer wall of the two connecting rods 14. By driving the main shaft 13 to rotate, the main shaft 13 drives the multiple connecting rods 14 to rotate synchronously, thereby causing the multiple connecting rods 14 to drive the two stirring paddles 15 to mix the raw materials. The two stirring paddles 15 are designed to cross each other. The two stirring paddles 15 are intersecting and crisscrossing inside the mixing chamber 5 to facilitate better and more uniform mixing of the raw materials and improve mixing efficiency. A feeding component is provided on the bottom outer wall of the mixing chamber 5 to facilitate the feeding of raw materials inside the mixing chamber 5, making it convenient for workers to operate.

[0020] The outer side wall of the mixing chamber 5 is rotatably connected to a protective plate 3, and a snap-fit ​​assembly 4 is provided between the protective plate 3 and the mixing chamber 5. The snap-fit ​​assembly 4 facilitates the fixing of the protective plate 3, and by rotating the protective plate 3, it is convenient to maintain the interior of the mixing chamber 5, while also allowing for observation and cleaning of the interior of the mixing chamber 5.

[0021] The feeding assembly includes a feeding port 8, which is fixedly connected to the bottom of the mixing chamber 5. A sealing plate 9 is rotatably connected to the outer wall of the feeding port 8, and the end of the sealing plate 9 rotatably passes through the mixing chamber 5 and is fixedly connected to a rotating plate 10. A fixing rod 12 adapted to the rotating plate 10 is provided on the outer wall of the mixing chamber 5. A toothed groove is provided on the outer wall of the rotating plate 10, and the end of the fixing rod 12 engages with the toothed groove. A spring 11 is provided between the fixing rod 12 and the mixing chamber 5, and the spring 11 is fixedly connected to the fixing rod 12 and the mixing chamber 5. By pressing the end of the fixing rod 12, the end of the fixing rod 12 that engages with the rotating plate 10 moves upward, thereby separating from the toothed groove. Then, by rotating the sealing plate 9, the raw material can be fed through the feeding port 8. Similarly, the feeding port 8 can also be closed by the sealing plate 9.

[0022] A bracket 6 is fixedly connected to the outer side wall of the frame 1, and a drive motor 7 is fixedly connected to the outer wall of the bracket 6. The output shaft of the drive motor 7 is fixedly connected to the main shaft 13. The drive motor 7 is started by an external power switch, so that the output shaft of the drive motor 7 drives the main shaft 13 to rotate.

[0023] The implementation principle of the plastic packaging material raw material mixing and homogenization device in this application embodiment is as follows: First, the plastic packaging material raw material is poured into the mixing chamber 5 through the feed port 2. Then, the drive motor 7 is started by the external power switch, so that the drive motor 7 drives the main shaft 13 to rotate. This causes the main shaft 13 to drive multiple symmetrical connecting rods 14 to rotate, which in turn drives two stirring paddles 15 to rotate. Through the cross design of the two stirring paddles 15, and the two stirring paddles 15 running through the interior of the mixing chamber 5, it is ensured that the two stirring paddles 15 fully mix the raw material, improving the mixing efficiency. At the same time, when discharging the material, the end of the fixing rod 12 can be pressed to move the end of the fixing rod 12 that meshes with the rotating plate 10 upward, loosening the fixing of the rotating plate 10, thereby facilitating the rotation of the closing plate 9. By rotating the closing plate 9, the raw material is discharged from the discharge port 8, thus completing the material discharge work.

[0024] The foregoing description, with reference to preferred embodiments, illustrates an exemplary embodiment of a plastic packaging material raw material mixing and homogenization apparatus provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
