Description

Technical Field

[0001] This application relates to the technical field of mixers, and specifically to a raw material mixer for plastic pelletizing. Background Art

[0002] When producing engineering plastic pellets, a high-speed mixer is needed to stir and mix materials such as plastic pellet raw materials and various additives to achieve uniform mixing of two or more materials. Stirring is used to increase the contact area between materials to promote chemical reactions and accelerate physical changes. The quality of material mixing directly determines the quality of engineering plastic pellets. Therefore, a raw material mixer is needed to fully mix the plastic raw materials so that the raw materials meet the production requirements.

[0003] For example, the patent with the publication number CN216968315U specifically discloses a raw material mixer for plastic pellet production. The motor drives the belt pulley to rotate, and the propeller blades on the stirring shaft rotate synchronously, facilitating the rapid conveyance of the raw materials in the feed hopper into the mixing tank. The propeller blades convey the raw materials to prevent the raw materials from clogging the pipeline, which is beneficial to improving the conveying efficiency of the raw materials. The heating tube rotates in the mixing tank to stir the raw materials, realizing the combination of feeding and stirring, with higher efficiency.

[0004] In the above patent, the device is provided with multiple groups of stirring blades and heating tubes, so that large lumps of raw materials are directly impacted and broken, improving the mixing effect. However, when stirring various raw materials using different production processes, it may be necessary to freely change the number of stirring blades to achieve the best mixing effect. Since the multiple groups of stirring blades in the above text are fixedly installed on the stirring rod and are not easy to adjust, this may limit the mixer when dealing with various raw materials or different process requirements, and it is difficult to achieve the optimal mixing effect.

[0005] Therefore, it is necessary to provide a raw material mixer for plastic pelletizing to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute prior art. Summary of the Invention

[0009] Further, a rotating cover is rotatably installed between every two groups of threaded holes on the rotating shaft. A clamping block is arranged inside the rotating cover, and the size of the clamping block is adapted to the size of the threaded hole.

[0010] Further, a temporary storage hole is arranged on the side of the rotating cover away from the threaded hole.

[0011] Further, the internal stirring blade is provided with an insertion block, and the connecting column is provided with an insertion hole, and the size of the insertion hole is adapted to the size of the insertion block.

[0012] Further, a fixing bolt is also arranged on the connecting head.

Specific implementation manner

[0024] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0026] As Figure 1 - Figure 2 shown, the present application provides a raw material mixer for plastic pelletizing, including a fixed seat 1, which is arranged in a plastic processing factory. At the same time, a mixing tank 2 is arranged on the fixed seat 1, and the mixing tank 2 is used for stirring and mixing the plastic raw materials to be pelletized to make them meet the production standards;

[0027] The mixing tank 2 includes a tank body 21, which is fixedly installed on the top of the fixed seat 1. At the same time, a rotating motor 22 is fixedly installed on one side of the tank body 21. The output end of the rotating motor 22 is fixedly installed with a rotating shaft 3 through a coupling. The rotating shaft 3 penetrates through the tank body 21 and is connected to the tank body 21 by bearings, and the rotating shaft 3 is adapted to rotate in the tank body 21 under the drive of the rotating motor 22;

[0028] As Figure 3 - Figure 5As shown, the rotating shaft 3 includes connecting rods 31 at both ends and a fixed rod 32 between two sets of connecting rods 31. Multiple sets of threaded holes 33 are provided on the fixed rod 32;

[0029] At the same time, a stirring assembly 4 is provided on the rotating shaft 3. The stirring assembly 4 includes multiple sets of connecting columns 41. External threads 42 are provided at the bottom of the connecting columns 41, and the size of the bottom of the connecting columns 41 is adapted to the size of the threaded holes 33. The connecting columns 41 are suitable for being fixedly installed on the rotating shaft 3 under the cooperation of the threaded holes 33 and the external threads 42, so that the connecting columns 41 can be easily installed on the rotating shaft 3 and can be quickly disassembled or replaced according to actual needs;

[0030] At the same time, an external stirring blade 43 is installed on the connecting column 41. Connecting heads 431 are provided at both ends of the external stirring blade 43, and the connecting heads 431 are inserted into the top of the connecting column 41. At the same time, fixing bolts 432 are also provided on the connecting heads 431. The fixing bolts 432 are used to fixedly install the connecting heads 431 on the connecting column 41, so that the external stirring blade 43 will not loosen when stirring the material, ensuring the stirring effect;

[0031] At the same time, multiple sets of internal stirring blades 44 are also provided on the connecting column 41. There is a certain distance between multiple sets of internal stirring blades 44. The internal stirring blades 44 are used for more detailed stirring of the interior of the material, such as breaking up material lumps and improving the mixing uniformity, etc. Multiple sets of insertion blocks are provided on the internal stirring blades 44. At the same time, multiple sets of insertion holes 5 are provided on the connecting column 41. The size of the insertion holes 5 is adapted to the size of the insertion blocks, so that different types of internal stirring blades 44 can be quickly installed on the connecting column 41. During maintenance or cleaning, the internal stirring blades 44 can be quickly disassembled from the connecting column 41, making it easier to inspect and replace worn or damaged parts during the maintenance process.

[0032] Such as Figure 5 - Figure 6 As shown, a rotating cover 34 is rotatably installed between every two sets of threaded holes 33 on the rotating shaft 3. A clamping block (not shown in the figure) is provided on the inner side of the rotating cover 34. The size of the clamping block is adapted to the size of the threaded holes 33. When the connecting column 41 is installed, there will be excess threaded holes 33 exposed on the outside. At this time, the rotating cover 34 can be rotated so that the clamping block in the rotating cover 34 is engaged with the threaded holes 33, thereby blocking the exposed threaded holes 33 on the outside to prevent materials and impurities from entering the threaded holes 33 and affecting subsequent use;

[0033] Meanwhile, a temporary storage hole 35 is provided on the side of the rotary cover 34 away from the threaded hole 33. The depth of the temporary storage hole 35 is less than that of the threaded hole 33, and a hydrophobic layer is provided in the temporary storage hole 35, so that the material will not remain inside the temporary storage hole 35 during the stirring process. When the connecting column 41 is installed inside the threaded hole 33, the rotary cover 34 can rotate into the temporary storage hole 35, so that the rotary cover 34 will not affect the stirring of the material.

[0034] In summary, when the types of materials to be stirred or the processing techniques are different, the connecting column 41 on the rotating shaft 3 can be quickly disassembled, and different types of outer stirring blades 43 and inner stirring blades 44 can be quickly replaced according to the stirring conditions, so as to ensure that the stirring tank 2 can optimize the stirring for specific materials, thereby achieving the best mixing effect.

[0035] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
