Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic granule processing technology, and in particular to a plastic granule mixing cylinder. Background Technology
[0002] In the production and processing of plastic granules, the mixing drum is a key piece of equipment for achieving uniform mixing of different types and properties of plastic granules. In existing technologies, to facilitate material discharge after mixing, some mixing drums have an inclined guide surface structure at the bottom, utilizing gravity to allow the material to flow automatically along the inclined surface, thus improving unloading efficiency to some extent. However, the inclined guide surface of this type of mixing drum has significant drawbacks in practical use. Specifically, because the side of the drum wall forms an angle with the horizontal plane, the matching scraping components cannot maintain uniform and close contact with the inclined surface, resulting in poor scraping of residual material. Furthermore, the inclined surface structure increases the manufacturing difficulty and assembly precision requirements of the scraping components, thereby affecting the cleaning efficiency and service life of the equipment.
[0003] On the other hand, some mixing drums, in order to simplify their structure, do not have inclined guide surfaces or other auxiliary unloading structures. After the material is mixed, workers must manually remove it from the drum or pour it out by manually turning the mixing drum. This operation method not only consumes a lot of manpower and resources and increases labor intensity, but may also cause material spillage or damage to the mixing drum due to improper operation. Especially in large-scale industrial production, it is difficult to meet the needs of efficient and automated production.
[0004] In summary, there is an irreconcilable contradiction between the convenience of unloading and the efficiency of cleaning residual materials in existing mixing drums. There is an urgent need to design a plastic granule mixing drum that can both facilitate the discharge of materials and facilitate efficient cleaning of the scraping components, so as to solve the problems of high labor intensity and cleaning difficulties in the existing technology. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a plastic granule mixing cylinder, which solves the technical problem that existing mixing cylinders require a large amount of manpower and resources to pour out materials or that it is difficult to scrape off residual materials.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A plastic granule mixing cylinder includes a base and a mixing cylinder. The base is provided with a first support column and a second support column. A mounting block is fixedly provided on the side of the first support column facing the second support column. A moving block is vertically slidably connected to the side of the second support column facing the first support column. The two ends of the mixing cylinder are respectively connected to the mounting block and the moving block. The side of the mixing cylinder is provided with a feed inlet and a discharge outlet. The discharge outlet is located on the side of the mixing cylinder near the second support column. A stirring assembly is rotatably arranged inside the mixing cylinder. A scraper is provided on the stirring assembly, and the scraper abuts against the inner wall of the mixing cylinder.
[0008] Working principle:
[0009] In operation, various plastic granules are fed into the mixing cylinder in batches through the inlet. The stirring assembly is then activated, mixing the materials within the cylinder. Simultaneously, a scraper contacts the inner wall of the mixing cylinder and, following the rotation of the stirring assembly, scrapes away any material adhering to the inner wall. After mixing, the moving block is moved downwards, causing the end of the mixing cylinder near the second support column to tilt downwards. The material then flows out automatically along the inclined surface under gravity and is ultimately collected and processed by workers.
[0010] Beneficial effects:
[0011] In this scheme, by setting a first support column, a second support column, an installation block, and a vertically sliding moving block, and by moving the moving block downward, the end of the mixing cylinder near the second support column is tilted downward, so that an inclined guide surface structure is formed on the side of the mixing cylinder. The material flows out automatically along the inclined surface under the action of gravity, which improves the unloading efficiency.
[0012] By setting up a mixing component and a scraper, the material adhering to the inner wall of the mixing cylinder is scraped off while the mixing component rotates, reducing the difficulty of cleaning and improving work efficiency. Attached Figure Description

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0017] Example:
[0018] like Figure 1 and Figure 2 As shown, a plastic granule mixing cylinder includes a base 1 and a mixing cylinder 2. A first support column 3 and a second support column 4 are fixedly disposed on the base 1. An installation block 5 is fixedly disposed on the side of the first support column 3 facing the second support column 4. A moving block 6 is vertically slidably connected to the side of the second support column 4 facing the first support column 3. The two ends of the mixing cylinder 2 are respectively connected to the installation block 5 and the moving block 6.
[0019] like Figure 1 and Figure 2 As shown, the second support column 4 has a sliding groove 9 on its side facing the first support column 3. A first motor 10 is fixed on the top surface of the second support column 4. The first motor 10 is a reversible motor. The output end of the first motor 10 is connected to a vertical first transmission shaft 11. The first transmission shaft 11 rotates through the top surface of the second support column 4 and rotates within the sliding groove 9. This rotation is achieved by bearings. It should be noted that bearings are existing technology, and those skilled in the art should understand their structure, principle, and usage. Specific details are not provided here. The rod segment of the first transmission shaft 11 within the sliding groove 9 is a threaded segment. The moving block 6 is threadedly connected to the outer circumference of the threaded segment of the first transmission shaft 11. The side of the moving block 6 abuts against the inner wall of the sliding groove 9. The bottom end of the first transmission shaft 11 is rotatably connected to the inner wall of the second support column 4 via bearings. Again, bearings are existing technology, and their structure and principle are not elaborated here. The method of driving the moving block 6 vertically by activating the first motor 10 is mechanized and automated, facilitating operation.
[0020] like Figure 1 and Figure 2 As shown, the movable block 6 is rotatably connected to an electric telescopic rod 12 on its side facing the first support column 3. The other end of the electric telescopic rod 12 is rotatably connected to the end face of the mixing cylinder 2. Both the rotatable connections between the movable block 6 and the first support column 3, and between the other end of the electric telescopic rod 12 and the mixing cylinder 2, are hinged. It should be noted that hinges are existing technology, and their structure and principle will not be elaborated here. The electric telescopic rod 12 can extend and retract in coordination with the vertical movement of the movable block 6, making it an important structure for achieving the tilting of the mixing cylinder 2. It should be noted that the electric telescopic rod 12 has sufficient load-bearing capacity to support the load when the mixing cylinder 2 is tilted.
[0021] like Figure 1 and Figure 2As shown, the mixing cylinder 2 has an inlet 7 and an outlet 8 on its side. The inlet 7 is located at the top of the mixing cylinder 2, and the outlet 8 is located at the bottom of the mixing cylinder 2, near the second support column 4. The inlet 7 is detachably connected to a first cover plate 18, and the outlet 8 is detachably connected to a second cover plate 19. Both detachable connections are achieved through bolt thread connections. Using bolts for detachable connections is existing technology, and its structure and principle will not be elaborated here. The first cover plate 18 and the second cover plate 19 can block the inlet 7 and the outlet 8.
[0022] like Figure 1 and Figure 2 As shown, a stirring assembly is rotatably installed inside the mixing cylinder 2. A second motor 13 is fixedly mounted on the end face of the mixing cylinder 2 near the first support column 3. The output end of the second motor 13 is connected to a second drive shaft 14. The second drive shaft 14 rotatably passes through the end face of the mixing cylinder 2 and into the mixing cylinder 2. The end of the second drive shaft 14 is rotatably connected to the inner wall of the mixing cylinder 2 via a bearing. Both of the above rotation methods are specifically achieved through bearings. It should be noted that bearings are existing technology, and their structure and principle will not be elaborated here. The stirring assembly includes several stirring rods 15, which are fixed on the outer periphery of the second drive shaft 14 and evenly distributed along the length of the second drive shaft 14. The second motor 13 is rotatably connected to the mounting block 5. The rotatable connection between the second motor 13 and the mounting block 5 is a hinge. It should be noted that hinges are existing technology, and their structure and principle will not be elaborated here. The method of mixing materials by starting the second motor 13 to drive the stirring rods 15 to rotate is mechanized and automated, and easy to operate.
[0023] like Figure 1 and Figure 2 As shown, the mixing assembly is equipped with a scraper that abuts against the inner wall of the mixing cylinder 2. The scraper includes two bottom scraping rods 16 and a side scraping rod 17 fixed between the ends of the two bottom scraping rods 16. It should be noted that both the side scraping rod 17 and the two bottom scraping rods 16 are made of food-grade rubber, possessing a certain degree of elasticity, allowing them to closely adhere to the cylinder wall, resulting in good scraping performance. Furthermore, their soft texture prevents damage to the inner wall of the mixing cylinder 2, and they exhibit good chemical stability, preventing contamination of plastic particles. The other ends of the two bottom scraping rods 16 are fixed to the second drive shaft 14. The side walls of the two bottom scraping rods 16 abut against the two end faces of the mixing cylinder 2, and the side walls of the side scraping rod 17 abut against the side of the mixing cylinder 2. Therefore, the scraper can completely cover the inner wall of the mixing cylinder 2 (two end faces + side face). This scraper has a relatively simple structure and manufacturing method, adheres well to the inner wall of the mixing cylinder 2, and provides good scraping performance.
[0024] Working principle:
[0025] When in use, open the first cover plate 18 and feed various plastic granules into the mixing cylinder 2 in batches through the feed inlet 7.
[0026] Then, the second motor 13 is started. The output of the second motor 13 drives the second transmission shaft 14 to rotate. The rotation of the second transmission shaft 14 drives several stirring rods 15 to rotate, thereby mixing the materials in the mixing cylinder 2.
[0027] The rotation of the second drive shaft 14 simultaneously drives the two bottom scraping rods 16 to scrape off the material adhering to the two end faces inside the mixing cylinder 2, and the side scraping rods 17 to scrape off the material adhering to the inner side of the mixing cylinder 2.
[0028] After mixing is completed, the first motor 10 is started. The output of the first motor 10 drives the first transmission shaft 11 to rotate. The rotation of the first transmission shaft 11 causes the moving block 6 to move vertically downward. During this process, the electric telescopic rod 12 extends and rotates, causing the mixing cylinder 2 to tilt downward at the end near the second support column 4.
[0029] Then, the second cover plate 19 is opened, and the material flows out automatically along the inclined surface under the action of gravity, and is finally collected and processed by workers.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
