Description

Technical Field

[0001] The utility model belongs to the technical field of stirring and mixing, and particularly relates to an ABS plastic mixer for experiments. Background Technique

[0002] ABS resin is one of the five major synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It also has the characteristics of easy processing, stable product size and good surface gloss. It is widely used in industrial fields such as machinery, automobiles, electronic appliances, instruments, textiles and construction, and is a thermoplastic engineering plastic with extremely wide uses. In the production and processing of ABS plastics, multiple processing procedures will be passed through. Among them, stirring and mixing equipment will be used to mix various required raw materials. When using general stirring equipment to stir and mix raw materials, all the raw materials will be poured into the interior of the stirring equipment at one time, and then stirred and mixed. However, since there is a certain ratio between the raw materials, the various raw materials are respectively stacked inside the stirring equipment, which is not convenient to stir and mix evenly, requires a longer time, reduces work efficiency, and also requires a high-power driving device to drive, resulting in unnecessary waste.

[0003] Therefore, there is a raw material stirring and mixing device for ABS plastic production with the publication number of "CN217292943U". The raw material stirring and mixing device for ABS plastic production includes a mixing barrel; a storage and feeding assembly, which includes an annular storage tank, an arc-shaped storage tank, an annular concave-convex plate, a feeding pipe and an electric control flow valve. The annular storage tank is fixedly installed at the upper end of the mixing barrel, and a plurality of arc-shaped storage tanks arranged in a ring are provided in the annular storage tank. An annular concave-convex plate is installed inside the mixing barrel, and a plurality of evenly distributed grooves are provided on the surface of the annular concave-convex plate. A plurality of feeding pipes are arranged in a ring inside the mixing barrel. One ends of the plurality of feeding pipes are respectively communicated with the bottoms of the plurality of arc-shaped storage tanks, and the other ends of the plurality of feeding pipes are all inclined towards the annular concave-convex plate. An electric control flow valve is installed on each of the plurality of feeding pipes; a stirring and discharging assembly; a dust-proof cover; a support seat. The raw material stirring and mixing device for ABS plastic production provided by the utility model has the advantage of high work efficiency.

[0004] However, for the above-mentioned raw material stirring and mixing device for ABS plastic production, although different types of raw materials are classified and placed in multiple arc-shaped storage tanks, and the opening sizes of each feeding pipe are controlled by an electric control flow valve, and various raw materials entering the inside of the mixing barrel are stirred in proportion, there are still the following obvious defects during use: Although multiple feeding pipes are set to automatically vertically feed multiple raw materials synchronously, then due to the different characteristics of the mixed raw materials, it is easy for the raw materials to be blocked in the feeding pipe due to excessive feeding during automatic vertical feeding, which will lead to the problem of blockage of the feeding pipe by the raw materials, thus affecting the speed of flowing feeding. Summary of the Utility Model

During the process of the pressurized unloading pipe inputting each raw material into the unloading pipe, the pressurized pump body applies pressure to the storage chamber, so that the material in the storage chamber can be discharged from the storage chamber to the unloading pipe at a constant unloading speed, which can ensure the stability of the unloading process and ensure that the raw materials will not be blocked in the pressurized unloading pipe by the air pressure applied during the unloading process, thereby allowing the raw materials to be discharged smoothly and enhancing the unloading efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all 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 work shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-3 , the present utility model provides a technical solution: a test ABS plastic mixer, including:

[0024] A mixing tank 1, an upwardly extending end of the mixing tank 1 is provided with a feeding pipe 2 for mixing and feeding a variety of raw materials, so that a preliminary mixing is carried out during the synchronous feeding of a variety of materials, which can shorten the mixing time of the mixing tank 1 for the raw materials. The upper outer end of the feeding pipe 2 is provided with a circular mixing and feeding tray 3 with several feeding inner cavities, so that a variety of original materials are stored in the mixing and feeding tray 3 and the synchronous feeding and mixing operation is carried out to improve the mixing efficiency of the raw materials. The mixing and feeding tray 3 is separated by a partition into several storage cavities 4 for storing different mixed raw materials, so that a variety of raw materials required for ABS plastic are respectively stored in the plurality of storage cavities 4 for synchronous feeding, shortening the feeding input time of the raw materials;

[0025] The annular pressure - applying air pipe 5 is evenly provided with pressure - applying and blanking branch pipes 6 extending to the inside of the material storage chamber 4 at its ends. The generated air pressure enters the material storage chamber 4 through the pressure - applying and blanking branch pipes 6, which can apply pressure to the raw materials during the output process to avoid blockage, and simultaneously avoid the phenomenon that the raw materials are output in a pile and blocked in the pipe orifice. One side of the annular pressure - applying air pipe 5 is connected to a pressure - applying pump body 7 installed at the upper end outside the mixing tank 1 and used for pressure - applying and blanking to the material storage chamber 4. The air pressure generated by the pressure - applying pump body 7 is conveyed to the inside of the material storage chamber 4 to ensure that the raw materials are smoothly output during the blanking process. The bottom of the mixing tank 1 is provided with a discharge box 8 for spirally outputting and blanking the raw materials after mixing in the mixing tank 1, so that the mixed raw materials are output in a spiral conveying manner to avoid the phenomenon that the raw materials are blocked in the pipeline and cannot be discharged.

[0026] One side of the material storage chamber 4 is provided with a pressure - applying and blanking pipe 9 penetrating through the inner circumference of the blanking pipe 2, so that the raw materials will not be blocked during the blanking process under the action of applied pressure. Electric control flow valves 10 are provided on the pressure - applying and blanking pipe 9 to control the amount of raw materials flowing into the inside of the mixing tank 1. The other side of the material storage chamber 4 is provided with a feed connection pipe 11 penetrating through and provided with a sealing valve, which is beneficial for sealing and pressurizing the inside of the material storage chamber 4. The annular pressure - applying air pipe 5 is sleeved on the outer bottom side of the blanking pipe 2, and the pressure - applying and blanking branch pipes 6 on the annular pressure - applying air pipe 5 are L - shaped outward at one end inside the material storage chamber 4. The end of the blanking pipe 2 is covered with a sealing cover plate 12 to prevent the raw materials from splashing out. In the middle of the lower end face of the sealing cover plate 12, a conical mixing guide block 13 is provided through a vertical rod to play a role in initially mixing the blanking of various raw materials.

[0027] On one side inside the mixing tank 1, a mixing shaft rod 14 is horizontally rotatably provided through a partition board, driving a mixing scraping screen plate 15 to rotate. The mixing shaft rod 14 is provided with a fan - shaped mixing scraping screen plate 15, which can stir the raw materials and clean the residues. A servo motor 16 is provided on one side inside the mixing tank 1 to drive the mixing shaft rod 14 to rotate. The servo motor 16 rotates through the partition board and is drivingly connected to one end of the mixing shaft rod 14. A conical blanking hopper 17 is provided between the mixing tank 1 and the discharge box 8, which can stir the raw materials during the blanking process. Inside the discharge box 8, a blanking spiral blade 18 is rotatably provided through a partition board, which can perform secondary mixing and stirring on the raw materials and push and convey them. A blanking motor 19 is provided on one side inside the discharge box 8 to drive the blanking spiral blade 18 to rotate. The rotating shaft of the blanking motor 19 is drivingly connected to one end of the blanking spiral blade 18. One side of the discharge box 8 is provided with a discharge connection pipe 20 penetrating to the outside to output the mixed raw materials.

[0028] Specifically, during use, first connect the feed connection pipe 11 on the storage chamber 4 to the feed pumps on each external storage tank, and transport each raw material to each discharge storage chamber 4 for storage. Subsequently, open the electric control flow valve 10 to allow each raw material to enter the feed pipe 2 from the pressurized feed pipe 9. To prevent the raw materials from aggregating and blocking at the pipe orifice during the feeding process, the pressure pump body 7 operates to generate pressure and transport it to the annular pressurized air pipe 5, and the air pressure in the annular pressurized air pipe 5 enters each storage chamber 4 through the pressurized feed branch pipe 6. At this time, the sealing valve is in a closed state, enabling the raw materials to be discharged from the storage chamber 4 into the feed pipe 2 at a constant feeding speed, ensuring the stability of the feeding process. Meanwhile, during the feeding process of the raw materials, the applied air pressure prevents the raw materials from blocking in the pressurized feed pipe 9, enhancing the smoothness of the feeding effect. Moreover, various raw materials can enter the mixing tank 1 in proportion. Under the action of gravity, the raw materials flow through the pressurized feed pipe 9 and impact the mixing guide block 13 from its port at a pressurized flow rate. The conical structure of the mixing guide block 13 disperses the raw materials, which is conducive to the mixing and stirring of the raw materials, saving the stirring time and reducing the output power of the stirring equipment. Then, the servo motor 16 drives the mixing shaft rod 14 and the mixing scraping screen plate 15 to mix and stir the raw materials during the falling process. The fan-shaped mixing scraping screen plate 15 contacts the inner wall of the mixing tank 1 during rotation, which can scrape and clean the sticky raw materials adhering to the inner wall. Finally, it flows into the discharge box 8, and the rotation of the discharge spiral blade 18 driven by the discharge motor 19 causes the mixed raw materials to flow and mix in one direction and be discharged from the discharge connection pipe 20.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
