Description

Technical Field

[0001] This utility model relates to the field of rubber compounding technology, and in particular to a rubber compounding device. Background Technology

[0002] The main raw materials for rubber production include monomers, additives, and fillers. Monomers are the main raw materials for synthetic rubber. They form high molecular weight substances through polymerization reactions. Commonly used monomers include butadiene, styrene, styrene-butadiene rubber, and isoprene. Additives are chemicals used to promote polymerization reactions, such as initiators and stabilizers. Fillers are substances used to adjust the properties of synthetic rubber, such as silica and calcium carbonate. During processing, the raw materials need to be mixed.

[0003] Patent announcement CN222096596U discloses a rubber raw material processing and mixing device, including a shell, a support plate fixed to the side wall of the shell; a first support seat fixed to the top of the side wall of the shell; a second motor fixed to the top of the shell; a second extension rod fixed to the output end of the second motor; the second extension rod extending into the interior of the shell; a plurality of stirring plates fixed to the middle of the second extension rod; a collection box fixed to the top of the first support seat; a first motor fixed to the bottom of the side wall of the collection box; and the first extension rod fixed to the output end of the first motor. This structure allows for more convenient and thorough addition of sulfur powder to the interior of the shell, enabling the sulfur powder to disperse more widely when entering the shell, thus allowing for more complete fusion of the sulfur powder and the rubber raw material, resulting in higher quality processed rubber.

[0004] The above devices achieve a more thorough fusion effect when mixing rubber raw materials. However, in actual mixing operations, the mixture will stick to the inside of the mixing device.

Since the residual raw materials are all inside the device, there is a problem of great difficulty in cleaning. Therefore, a rubber mixing processing device is proposed to solve the above problems.

One end of the electric push rod 46 is fixedly connected to the inside of the push plate 45. After the electric push rod 46 works, it pushes and pulls the push plate 45.

[0040] In actual operation, the device is first connected to the power supply. The raw materials for processing are fed into the feeding hopper 383. Then, the second motor 397 drives the first gear 398 to rotate, the first gear 398 drives the second gear 399 to rotate, the second gear 399 drives the stirring rod 36 to rotate, and the stirring rod 36 drives the stirring blade 37 to rotate to mix the raw materials. During this period, the stirring rod 36 drives the connecting rod 39 to rotate, and the connecting rod 39 drives the scraper 38 to rotate to scrape off any raw materials that may be adhering to the inner wall of the mixing tank 2, thereby achieving the purpose of thorough mixing.

[0041] While the above stirring work is being carried out, the electric push rod 46 pushes the push plate 45 after it is activated.

This can shake the raw materials inside the mixing tank 2, which can effectively avoid the situation that the raw materials at the bottom cannot be quickly stirred and thus cause uneven mixing. Stirring is carried out while shaking, which improves the stirring quality and mixing efficiency. At the same time, this method controls the mixing tank 2 to flip over, and can also flexibly adjust the cleaning posture when cleaning the mixing tank 2 in the future, which provides convenience for the cleaning work.

[0042] Finally, after the mixing operation is completed, the valve is opened, and the mixture can be discharged through the discharge pipe 384. When it is necessary to clean the inside of the mixing tank 2, the first motor 395 works and drives the connected threaded rod 394 to rotate. This threaded rod 394 drives the external pulley 385 to rotate. This pulley 385 drives another pulley 385 to rotate through a belt. At this time, the two threaded rods 394 rotate synchronously. After the threaded rods 394 rotate, they drive the control plate 392 to move up and down. The control plate 392 drives the cover plate 33 to move. The cover plate 33 drives the stirring rod 36 and the mounting plate 35 to move, thereby realizing the separation of the mixing tank 2 from the cover plate 33 and the mounting plate 35. The separated stirring blade 37 is directly exposed to the outside, and the user can directly clean it. In addition, the user can also directly clean the inside of the mixing tank 2 through the mounting groove 34, which greatly improves the convenience of the cleaning process.
