Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a mixer for plastic processing. Background Technology

[0002] In plastic processing, mixers are crucial pretreatment equipment used to uniformly mix plastic raw materials (such as granules and powders) with additives (such as color masterbatches, stabilizers, and fillers) to ensure product quality in subsequent molding processes (such as injection molding, extrusion, and blow molding). Mixers utilize high-speed rotating blades to generate shear and centrifugal forces, rapidly mixing materials. They typically consist of a tank, mixing blades, a drive motor, and a top cover. However, the top cover, secured with bolts and nuts, is difficult to install and disassemble, time-consuming, and labor-intensive, presenting certain drawbacks. Therefore, we propose a new type of mixer for plastic processing. Utility Model Content

Then, the discharge pipe 102 can be opened by controlling the electric valve 103, and the mixture can be discharged through the discharge pipe 102 after opening.

[0030] Specifically, the fixing seat 200 is fixedly installed on the outside of the mixing tank 100. The four fixing seats 200 are distributed in a circle. Each of the four fixing seats 200 has an insertion hole. In use, the fastening component 500 can be fixed through the fixing seat 200 so that the top cover 300 can be fixed through the fastening component 500.

[0031] Specifically, the top cover 300 is inserted into the groove 104. The top of the top cover 300 is fixedly equipped with an air inlet pipe 301 and an exhaust pipe 302. The top of the top cover 300 is also fixedly equipped with a lifting ring 303, an adding pipe 304, and a barometer 305. The two lifting rings 303 are symmetrically distributed. In use, the top cover 300 can seal the mixing tank 100. A certain amount of gas can be delivered into the mixing tank 100 through the air inlet pipe 301 and then discharged through the exhaust pipe 302 for ventilation and to facilitate the testing of the device's sealing performance. The lifting rings 303 can be connected to hooks for hoisting. A certain amount of raw materials can be added to the mixing tank 100 through the adding pipe 304. The barometer 305 can detect the air pressure inside the mixing tank 100.

[0032] Specifically, the mixing mechanism 400 is fixedly mounted on the top cover 300. During use, the mixing mechanism 400 generates shearing force and centrifugal force through high-speed rotating blades, which makes the materials mix quickly for processing.

[0033] Specifically, the fastening assembly 500 includes a rotating rod 501 inserted into the fixed base 200, a base 502 bolted to the bottom of the rotating rod 501, a fastening rod 503 threaded to the rotating rod 501, a fastening seat 504 bearing-connected to the fastening rod 503, and a first spring 505 fixedly disposed on the inner side of the rotating rod 501 and the fastening seat 504. The fastening rod 503 has threads on its outer side and is T-shaped. In use, rotating the fastening rod 503 can drive the fastening seat 504 to move up and down, so that the top cover 300 can be fixed by the contact of the fastening seat 504. The rotating rod 501 can drive the fastening rod 503 and the fastening seat 504 to rotate for fixation. Then, the fastening assembly 500 can be disassembled by removing the base 502 for replacement and maintenance. Afterwards, the first spring 505 can hold the fastening seat 504 against it, which can enhance the fixing effect of the fastening seat 504.

[0034] Specifically, the baffle 600 is fixedly installed at the top of the top cover 300. The baffle 600 is annular. In use, the baffle 600 can form an annular groove with the mixing tank 100.

In use, the first fixing ring 701 and the second fixing ring 703 have the same structure. The elasticity of the second spring 702 allows the sealing ring 704 to abut against the top cover 300, thereby achieving dynamic sealing. Furthermore, it can improve the sealing performance when used in conjunction with the fastening assembly 500.

[0036] The working principle and usage process of this utility model are as follows: In use, the fastening rod 503 of the fastening assembly 500 can be rotated upwards. The rotating fastening rod 503 can drive the fastening seat 504 to move upwards. After moving to a suitable height, the rotating rod 501 can be rotated until the fastening assembly 500 no longer obstructs the top cover 300. Then, the lifting ring 303 is connected to the lifting hook, and the top cover 300 is lifted using a lifting device for quick disassembly. During installation, the top cover 300 can be placed in the groove 104, and the rotating rod 501 is rotated to drive the fastening seat 504 until it is securely fastened. The mounting base 504 is directly above the top cover 300. Then, rotate the fastening rod 503 downwards. The rotating fastening rod 503 will drive the mounting base 504 downwards until the mounting base 504 abuts against the top cover 300. The top cover 300 can then be installed quickly. When testing the sealing performance, first, a certain amount of gas is supplied to the mixing tank 100 through the air inlet pipe 301. Then, a certain amount of clean water is injected into the groove between the baffle 600 and the mixing tank 100. Then, observe whether bubbles are generated. If bubbles are generated, it indicates air leakage. Conversely, if no bubbles are generated, it indicates good sealing performance.
