Description

Technical Field

[0001] This utility model relates to the field of mixing and adjusting equipment technology, and in particular to a raw material mixing and adjusting equipment for polymer packaging materials. Background Technology

[0002] In the production of polymer materials, the uniform mixing of raw materials is a crucial step in ensuring the performance and quality of the final product. Currently, widely used industrial raw material mixing devices typically include basic functional modules such as stirring and heating mechanisms, enabling preliminary mixing and heating of materials. These devices use the rotational motion of mechanical stirring blades to shear and mix the materials, and an external heating device to heat the mixing container to meet the specific mixing temperature requirements of the process.

[0003] A search revealed Chinese Patent Publication No. CN222096602U, which discloses a raw material mixing device for polymer material production. This utility model relates to the field of polymer rubber and plastic products technology and proposes a stirring device for mixing rubber and plastic polymer materials. It includes a mixing tank with a lid slidably fitted to its top. A stirring mechanism is located inside the lid, comprising a rotating shaft rotatably connected to the center of the inner side of the lid. A motor is fixedly mounted on the top of the lid, and the motor's output shaft is fixedly connected to the rotating shaft. A universal coupling is fixedly connected to the bottom of the rotating shaft, and a stirring shaft is fixedly connected to the bottom of the universal coupling. Several stirring rods are fixedly connected to the outer side of the stirring shaft, and a mounting plate is fixedly connected to the top of the stirring shaft. Several heating elements are fixedly connected to the outer edge of the bottom of the mounting plate. A push-swing assembly is located at one end of the inner side of the lid. The aforementioned raw material mixing device for polymer material production has the following shortcomings:

[0004] Although the aforementioned patent allows the stirring rod to agitate different layers of material in the vertical direction when the stirring shaft is tilted, thus enabling the material to be mixed in different directions and greatly improving the mixing speed, it lacks a wall scraping device and cannot actively scrape the inner wall of the stirring chamber simultaneously during the heating and mixing process. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a raw material mixing and adjustment device for polymer packaging materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] A raw material mixing and adjustment device for polymer packaging materials, such as Figure 1 and Figure 2 As shown, it includes a base 6, four bases 3 are fixedly connected to the bottom of the base 6, and a stirring chamber assembly 5 is fixedly connected to the inner circumference of the base 6. A heating device 2 is fixedly connected to the bottom of the outer circumference surface of the stirring chamber assembly 5, and a discharge port is opened at the bottom of the stirring chamber assembly 5. A valve is provided on the discharge port, and the heating device 2 is a Thermon HSX model.

[0028] like Figure 1 and Figure 3 As shown, four supports 1 are fixedly connected to the outer circumferential surface of the stirring chamber assembly 5, a rotating assembly 4 is threadedly connected to the top of the stirring chamber assembly 5, and a stirring roller assembly 7 is fixedly connected to the bottom of the rotating assembly 4.

[0029] like Figure 3 As shown, the rotating assembly 4 includes a housing 46, which is threaded to the top of the stirring chamber assembly 5. A rotating motor 41 is fixedly connected to the top of the housing 46, and a rotating shaft 42 is fixedly connected to the output end of the rotating motor 41. A drive gear 45 is fixedly connected to the bottom end of the rotating shaft 42. A maintenance chamber is provided on the housing 46.

[0030] like Figure 3As shown, a gear ring 47 is rotatably connected to the inner circumference of the outer shell 46. Three driven gears 44 are meshed on the inner circumference of the gear ring 47, and the centers of the three driven gears 44 are rotatably connected to the top inner wall of the outer shell 46 through a fixed shaft 43. The three driven gears 44, the driving gear 45 and the gear ring 47 mesh with each other.

[0031] After the rotating motor 41 is powered on, it starts to work and drives the rotating shaft 42 at its output end to rotate. The driving gear 45 at the bottom of the rotating shaft 42 rotates accordingly. The driving gear 45 is simultaneously engaged with three driven gears 44. Since the three driven gears 44 are rotatably connected to the bottom of the inner cavity of the housing 46 through the fixed shaft 43, the driven gears 44 generate rotational motion under the drive of the driving gear 45. The three driven gears 44 also mesh together with the inner teeth of the gear ring 47, thereby driving the gear ring 47 to rotate at the bottom of the housing 46.

[0032] like Figure 4 As shown, the mixing chamber assembly 5 includes a mixing chamber 52, which is fixedly connected to the inner circumference of the base 6. A thread 51 is provided on the outer circumference of the top of the mixing chamber 52, and an inlet is fixedly connected to the outer circumference surface of the mixing chamber 52.

[0033] The stirring chamber assembly 5 provides a closed reaction space for the mixing process, while the thread 51 is used to connect the rotating assembly 4, and the feed port is used to add materials into the stirring chamber 51.

[0034] like Figure 3 and Figure 5 As shown, the stirring roller assembly 7 includes scraper columns 72, four scraper columns 72 are fixedly connected to the bottom of the toothed ring 47, and an annular hole is opened on the inner circumference of the outer shell 46 near the toothed ring 47. The scraper columns 72 are slidably connected in the annular hole, and three or more shearing blades 71 are fixedly connected to one side of each of the four scraper columns 72.

[0035] like Figure 3 and Figure 5 As shown, the stirring roller assembly 7 also includes a stirring column 74, which is fixedly connected to the bottom end of the drive gear 45, and three or more stirring blades 73 are fixedly connected to the circumferential surface of the stirring column 74.

[0036] Driven by the drive gear 45, the stirring column 74 rotates, and the multiple stirring blades 73 fixed on its circumferential surface generate strong shearing action and axial circulation flow on the material in the central area of ​​the mixing chamber 52, forming the main mixing zone and ensuring the main uniformity of the material.

[0037] The gear ring 47 drives four scraper columns 72 to revolve along the inner wall of the mixing chamber 52. During the revolve, multiple shear blades 71 installed on the other side of the scraper columns 72 generate additional shearing action on the material in the middle area of ​​the mixing chamber 52, which interferes with and complements the flow field formed by the central mixing blade 73. At the same time, the scraper columns 72 continuously scrape off the material adhering to the inner wall of the mixing chamber 52 during the revolve, effectively preventing the material from stagnating and solidifying on the wall surface.

[0038] Working principle: In use, materials are first added into the mixing chamber 52 through the inlet, then the equipment is started, and the rotating motor 41 begins to work, driving the rotating shaft 42 at its output end to rotate. The drive gear 45 at the end of the rotating shaft 42 rotates accordingly, and the power of the drive gear 45 is transmitted to the mixing column 74, driving it to rotate around its own axis. Multiple mixing blades 73 fixed to the circumferential surface of the mixing column 74 rotate at high speed, mixing and blending the materials in the central area of ​​the mixing chamber 52. While rotating, the drive gear 45 meshes with and drives three driven gears 44 connected to it. Since the fixed shafts 43 of these three driven gears 44 are fixed to the bottom of the outer casing 46, they cannot revolve around the central axis, but can only rotate under the drive of the rotating drive gear 45. These three driven gears 44 also simultaneously interact with a gear ring 47. In the meshing process, under the action of the transmission structure, when the drive gear 45 rotates, it drives the gear ring 47 to rotate inside the outer shell 46 in the opposite direction to the rotation of the drive gear 45. Four scraper columns 72 are fixedly connected to the bottom of the gear ring 47. The scraper columns 72 extend into the mixing chamber 52 through the annular hole. Therefore, the rotation of the gear ring 47 will drive the four scraper columns 72 to revolve around the inner wall of the mixing chamber 52. Each scraper column 72 has multiple shearing blades 71 installed on one side. During the revolve, these shearing blades 71 generate additional shearing action on the material in the middle and edge areas of the mixing chamber 52 and interfere with the flow field of the central mixing blade 73, which greatly enhances the mixing effect and eliminates the mixing dead zone. After the work is completed, the valve set on the discharge port is opened to allow the mixed material to be discharged through the discharge port.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
