Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastics processing, and in particular to a high-speed stirring device for the preparation of thermoplastic elastomers. Background Technology
[0002] Thermoplastic elastomers (TPEs) are a class of materials that combine the elastic properties of elastomers (rubber) with the processing performance of thermoplastics. They exhibit good flexibility and tensile strength at room temperature, allowing them to deform like rubber, but can be processed and molded like plastics after heating. TPEs are widely used in various fields such as automotive, home appliances, medical devices, and consumer goods, and are favored for their excellent performance and ease of processing. TPEs are typically composed of a mixture of various components (such as a plastic matrix, elastomer, and additives). High-speed mixing equipment ensures that these components are thoroughly and uniformly mixed, preventing material separation and thus improving product consistency and quality.
[0003] In the process of developing this application, the inventors discovered the following problems with the existing technology: Conventional high-speed mixing equipment typically only has basic mixing functions, and materials are often only stirred within a certain range. This results in some materials remaining at the bottom or on the inner wall of the equipment, thereby reducing the utilization rate of raw materials and causing material waste. In addition, due to material retention, operators need to clean the equipment regularly, which not only increases the complexity of the process but also increases the maintenance workload, further affecting production efficiency.
[0004] Therefore, those skilled in the art have provided a high-speed stirring apparatus for the preparation of thermoplastic elastomers to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-speed stirring device for the preparation of thermoplastic elastomers. This invention can scrape off the material adhering to the inner wall during operation.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A high-speed mixing device for preparing thermoplastic elastomers includes a bottom mixing tank, an upper mixing tank, and a high-speed motor. A support frame is fixedly installed on the lower outer side of the bottom mixing tank. A connecting block is fixedly installed at the middle position of the upper part of the four sides of the outer side of the bottom mixing tank. A limiting block is fixedly installed at each of the four corners of the upper end of the bottom mixing tank. A heating plate is fixedly installed inside the inner wall of the bottom mixing tank. A second mounting ring is fixedly sleeved on the lower outer side of the output end of the high-speed motor. A second limiting block is rotatably installed on the lower side of the output end of the high-speed motor.
[0008] The upper mixing tank is rotatably equipped with a rotating column at its upper end. Eight stirring paddles are fixedly fitted on the outer side of the rotating column. A scraper is fixedly fitted on the lower outer side of the rotating column. A first mounting ring is rotatably fitted on the upper outer side of the rotating column. A second limiting groove is opened at the upper end of the rotating column. A second connecting block is fixedly installed at the middle position of the lower end of the outer perimeter of the upper mixing tank. A first limiting groove is opened at each of the four corners of the lower end of the upper mixing tank. Four through holes are opened at the middle position of the lower end of the upper mixing tank. A feed inlet is fixedly installed on both sides of the upper end of the upper mixing tank.
[0009] Furthermore, the upper mixing tank is placed on top of the bottom mixing tank.
[0010] Furthermore, the four No. 1 limiting blocks are placed inside the four No. 1 limiting slots, and the four No. 1 connecting blocks are fixedly connected to the four No. 2 connecting blocks by bolts.
[0011] Furthermore, the second limiting block is placed inside the second limiting groove, and the first mounting ring and the second mounting ring are fixedly connected by bolts.
[0012] Furthermore, four of the eight agitators are rotatably disposed inside the bottom agitator, and the other four of the eight agitators are rotatably disposed inside the upper agitator.
[0013] Furthermore, the scraper contacts the inner wall of the bottom mixing tank, and the four through holes are located at the upper end of the bottom mixing tank.
[0014] Furthermore, valves are fixedly installed at the outer ends of both feed inlets, and the high-speed motor is located at the upper end of the upper mixing tank.
[0015] This utility model has the following beneficial effects:
[0016] This invention proposes a high-speed mixing device for the preparation of thermoplastic elastomers. When placing the upper mixing tank on the lower mixing tank, first align the four No. 1 limiting blocks with the four No. 1 limiting grooves. At this point, the four No. 1 connecting blocks will contact the four No. 2 connecting blocks. Then, screw in the bolts to quickly fix the upper and lower mixing tanks. After adding material through the inlet, start the high-speed motor. The mixing in the upper mixing tank can thoroughly mix various materials. Because the bottom of the upper mixing tank is sloped, the material will enter the lower mixing tank through the bottom through-hole. At this time, activate the heating plate to fully melt the material in the lower mixing tank. The rotation of the agitator stirs the molten material in the bottom mixing tank, while the scraper effectively removes residue adhering to the inner wall, ensuring full utilization of the material. The upper and lower mixing tanks are made of different materials, preventing heat transfer from the bottom mixing tank to the upper mixing tank, thus preventing the melting of materials that have not entered the bottom mixing tank. In addition, the inclined bottom design of the upper mixing tank helps the material flow smoothly to the bottom mixing tank, reducing material retention in the equipment and ensuring effective transfer and utilization of raw materials. The installation process of this new type is simple, and operators can quickly get started, reducing training costs and time and improving overall work efficiency. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Reference Figures 1-8 One embodiment provided by this utility model:
[0029] A high-speed mixing device for preparing thermoplastic elastomers includes a bottom mixing tank 1, an upper mixing tank 2, and a high-speed motor 9. A support frame 18 is fixedly installed on the lower outer side of the bottom mixing tank 1. A connecting block 17 is fixedly installed at the middle position of the upper part of each of the four outer sides of the bottom mixing tank 1. A limiting block 14 is fixedly installed at each of the four corners of the upper part of the bottom mixing tank 1. A heating plate 3 is fixedly installed inside the inner wall of the bottom mixing tank 1. A second mounting ring 10 is fixedly fitted on the lower outer side of the output end of the high-speed motor 9. A second limiting block 11 is rotatably installed on the lower side of the output end of the high-speed motor 9. A rotating column 4 is rotatably installed on the upper part of the upper mixing tank 2. Eight mixing blades 5 are fixedly fitted on the outer side of the rotating column 4. A scraper 6 is fixedly fitted on the lower outer side of the rotating column 4. A first mounting ring 7 is rotatably fitted on the upper outer side of the rotating column 4. A second limiting groove 8 is opened on the upper part of the rotating column 4. A second limiting groove 8 is fixedly installed at the middle position of the lower part of each of the four outer sides of the upper mixing tank 2. The upper mixing tank 2 has four corner limit grooves 13 at its lower end, four through holes 12 at its lower end near the middle, and feed inlets 15 fixedly installed on both sides of its upper end. The upper mixing tank 2 is placed on top of the bottom mixing tank 1. Four limit blocks 14 are placed inside the four limit grooves 13. Four connecting blocks 17 and four connecting blocks 16 are fixedly connected by bolts. A limit block 11 is placed inside the second limit groove 8. A mounting ring 7 and a mounting ring 10 are fixedly connected by bolts. Four of the eight mixing paddles 5 are rotatably installed inside the bottom mixing tank 1, and the other four are rotatably installed inside the upper mixing tank 2. The scraper 6 is in contact with the inner wall of the bottom mixing tank 1. The four through holes 12 are located at the upper end of the bottom mixing tank 1. Valves are fixedly installed at the outer ends of the two feed inlets 15. The high-speed motor 9 is located at the upper end of the upper mixing tank 2.
[0030] Specifically, when placing the upper mixing tank 2 on the lower mixing tank 1, first align the four No. 1 limiting blocks 14 with the four No. 1 limiting slots 13. At this time, the four No. 1 connecting blocks 17 and the four No. 2 connecting blocks 16 will contact each other. Then, screw in the bolts to quickly fix the upper mixing tank 2 and the lower mixing tank 1. After adding materials through the feed inlet 15, start the high-speed motor 9. The mixing in the upper mixing tank 2 can fully mix various materials. Since the bottom of the upper mixing tank 2 is sloping, the materials will enter the lower mixing tank 1 through the bottom through hole 12. At this time, start the heating plate 3 to fully melt the materials in the lower mixing tank 1. Due to the stirring paddle 5 As the bottom mixing tank 1 rotates, the melted material inside is also stirred. At the same time, the scraper 6 effectively removes residues adhering to the inner wall, ensuring full utilization of the material. The upper mixing tank 2 and the bottom mixing tank 1 are made of different materials, and the heat from the bottom mixing tank 1 will not be transferred to the upper mixing tank 2, thus preventing the material that has not entered the bottom mixing tank 1 from melting. In addition, the inclined bottom design of the upper mixing tank 2 helps the material flow smoothly to the bottom mixing tank 1, reducing material retention in the equipment and ensuring the effective transfer and utilization of raw materials. The installation process of this new type is simple, and operators can quickly get started, reducing training costs and time and improving overall work efficiency.
[0031] Working principle: When placing the upper mixing tank 2 on the lower mixing tank 1, first align the four No. 1 limiting blocks 14 with the four No. 1 limiting slots 13. At this time, the four No. 1 connecting blocks 17 and the four No. 2 connecting blocks 16 will contact each other. Then, screw in the bolts to quickly fix the upper mixing tank 2 and the lower mixing tank 1. After adding materials through the feed port 15, start the high-speed motor 9. The mixing in the upper mixing tank 2 can fully mix various materials. Since the bottom of the upper mixing tank 2 is sloping, the materials will enter the lower mixing tank 1 through the bottom through hole 12. At this time, start the heating plate 3 to fully melt the materials in the lower mixing tank 1. Due to the rotation of the stirring paddle 5, the melted materials in the lower mixing tank 1 will also be stirred. At the same time, the scraper 6 can effectively scrape off the residues adhering to the inner wall to ensure full utilization of the materials. The upper mixing tank 2 and the lower mixing tank 1 are made of different materials, and the heat of the lower mixing tank 1 will not be transferred to the upper mixing tank 2, thereby preventing the materials that have not entered the lower mixing tank 1 from being melted.
