In addition, the raw materials are not filtered, and impurities will be mixed into the raw materials and stirred together, resulting in low work efficiency and waste of resources, manpower and material resources. Therefore, a rubber raw material stirring device is needed.

[0004] However, when processing fluorosilicone special rubber, multiple raw materials need to be stirred and mixed in a certain ratio in order to obtain qualified fluorosilicone special rubber. The rubber raw material stirring device mentioned in the above patent is not convenient for limiting the amount of raw materials added when adding the rubber raw materials, which is not conducive to the processing and production of fluorosilicone special rubber.

[0005] Therefore, in view of the above problems, a quantitative mixing and stirring device for producing fluorosilicone special rubber is proposed. Utility Model Content

[0030] Example:

[0031] See also Figure 1-4 A quantitative mixing and stirring device for the production of fluorosilicone special rubber includes a stirring tank 1, a sealing cover 2 is installed on the top of the stirring tank 1, a raw material classification cylinder 3 is installed on the top of the sealing cover 2, a stirring component 4 is installed inside the raw material classification cylinder 3, the raw material classification cylinder 3 passes through the sealing cover 2, a quantitative feeding disk 5 is installed at the bottom of the sealing cover 2, the quantitative feeding disk 5 is adapted to the stirring component 4, and a PLC controller 6 is fixedly connected to the outer wall of the stirring tank 1, and the PLC controller 6 is electrically connected to the quantitative feeding disk 5 and the stirring component 4.

[0032] In this solution, the stirring tank 1 is used to facilitate stirring and mixing the raw materials of fluorosilicone special rubber. The sealing cover 2 seals the stirring tank 1 and limits the position of the raw material classification cylinder 3. The raw material classification cylinder 3 limits the position of the stirring component 4. The stirring component 4 stirs and mixes the raw materials of fluorosilicone special rubber in the stirring tank 1. The quantitative feeding plate 5 is used to weigh the raw materials in the raw material classification cylinder 3 and transmit the weighing signal to the PLC controller 6. The PLC controller 6 controls the activity of the quantitative feeding plate 5 according to the signal, so as to facilitate the quantitative feeding of different raw materials of fluorosilicone special rubber.

[0033] The raw material classification cylinder 3 comprises a cylinder body 301 , a plurality of partition plates 302 arranged at equal intervals are fixedly connected inside the cylinder body 301 , and a bottom end of the partition plate 302 is fixedly connected to a bottom plate 303 .

[0034] In this solution, the cylinder 301 is divided into a plurality of small spaces by the partition plate 302, so that the user can put the raw materials of the fluorosilicone special rubber into the space by classification, and a plurality of raw materials can be put into the space in a quantitative manner at one time.

[0035] The stirring assembly 4 includes a hollow cylinder 401, which is installed on the top of the chassis 303 and fixedly connected to the partition plate 302. A motor 402 is fixedly connected to the inside of the hollow cylinder 401 and located at the top of the chassis 303. The transmission end of the motor 402 is fixedly connected to a transmission shaft 403. The transmission shaft 403 penetrates the chassis 303 and extends to the inside of the stirring tank 1. The outer wall of the transmission shaft 403 is fixedly connected to a plurality of stirring blades 404 that are equidistantly arranged.

[0036] In this solution, the hollow cylinder 401 isolates the space of the cylinder 301 to facilitate the installation of the motor 402. The motor 402 drives the transmission shaft 403 to rotate, and the transmission shaft 403 drives the stirring blade 404 to rotate. The stirring blade 404 stirs and mixes the raw materials of the fluorosilicone special rubber in the stirring tank 1.

[0037] The quantitative feeding plate 5 includes a fixed plate 501, which is fixedly connected to the chassis 303 and matched with the partition plate 302. A movable block 502 is installed at the bottom end of the fixed plate 501, which is rotatably connected to the chassis 303 and matched with the fixed plate 501 and the partition plate 302.

[0038] In this solution, the movement of the movable block 502 facilitates the weighing and subsequent placement of the fluorosilicone special rubber raw material in the hollow cylinder 401.

[0039] The bottom end of the fixed plate 501 is fixedly connected with an electromagnet 503, the outer wall of the movable block 502 is fixedly connected with a magnetic block 504, the magnetic block 504 and the electromagnet 503 are arranged opposite to each other with opposite poles, and the outer walls of the magnetic block 504 and the electromagnet 503 are both installed with shielding covers.

[0040] This solution facilitates the movement of the movable block 502 by cooperating with the electromagnet 503 and the magnetic block 504. When the electromagnet 503 is energized, the electromagnet 503 and the magnetic block 504 repel each other. After the power is cut off, the electromagnet 503 and the magnetic block 504 will attract each other. When the electromagnet 503 is energized, the repulsive force is greater than the attractive force, thereby facilitating the movement of the movable block 502. When the electromagnet 503 is energized, the movable block 502 leaves the bottom end of the fixed plate 501. When the electromagnet 503 is de-energized, the movable block 502 moves toward the bottom end of the fixed plate 501.

[0041] The movable block 502 includes a rotating shaft 50201 , which is rotatably connected to the chassis 303 . A connecting plate 50202 is fixedly connected to the bottom end of the rotating shaft 50201 , and the connecting plate 50202 is adapted to the fixed plate 501 .

[0042] In this solution, the connecting plate 50202 is connected to the chassis 303 via the rotating shaft 50201 , thereby limiting the position of the chassis 303 .

[0043] The top of the connecting plate 50202 is fixedly connected with a weighing sensor 50203 , and the top of the weighing sensor 50203 is fixedly connected with a baffle 50204 . The baffle 50204 is compatible with the fixing plate 501 and the partition plate 302 .

[0044] In this solution, the position of the weighing sensor 50203 is limited by the connecting plate 50202. The weighing sensor 50203 cooperates with the baffle 50204 to weigh the fluorosilicone special rubber raw material in the hollow cylinder 401. The weighing sensor 50203 transmits the sensing signal to the PLC controller 6. When a certain weight is reached, the PLC controller 6 controls the electromagnet 503 to cut off the power, so that the movable block 502 moves to the bottom end of the fixed plate 501, and the fluorosilicone special rubber raw material in the hollow cylinder 401 falls into the stirring tank. At this time, the motor 402 drives the transmission shaft 403 to rotate, and the transmission shaft 403 drives the stirring blade 404 to rotate, and the stirring blade 404 stirs and mixes the fluorosilicone special rubber raw material in the stirring tank 1.

[0045] Working principle: put the fluorosilicone special rubber raw materials into the hollow cylinder 401 respectively, and the weighing sensor 50203 and the baffle 50204 cooperate to weigh the fluorosilicone special rubber raw materials in the hollow cylinder 401, and the weighing sensor 50203 transmits the induction signal to the PLC controller 6. When a certain weight is reached, the PLC controller 6 controls the electromagnet 503 to cut off the power, so that the movable block 502 moves to the bottom end of the fixed plate 501, and the fluorosilicone special rubber raw materials in the hollow cylinder 401 fall into the stirring tank. At this time, the motor 402 drives the transmission shaft 403 to rotate, and the transmission shaft 403 drives the stirring blade 404 to rotate, and the stirring blade 404 stirs and mixes the fluorosilicone special rubber raw materials in the stirring tank 1. When the fluorosilicone special rubber raw materials in the hollow cylinder 401 are lower than the threshold value, the electromagnet 503 is energized, and the movable block 502 leaves the bottom end of the fixed plate 501 to seal the fluorosilicone special rubber raw materials.

[0046] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
