[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0023] according to Figure 1 - Figure 6 As shown, this embodiment provides a dissolving holding device for manufacturing rubber products, including a tank body 1, a vibration component, a multiple stirring component and a controller 6. The upper and lower ends of the tank body 1 are respectively provided with a sealing cover 2 and a support leg 3. A partition for placing a chassis 4 is provided inside the tank body 1. A reduction motor 5 is installed inside the chassis 4. The output shaft of the reduction motor 5 passes through the bottom of the partition and is fixed to the multiple stirring component through a coupling.

[0024] A plurality of vibration components for assisting in mixing the solvent and the rubber particles are fixed at the bottom of the tank body 1, a controller 6 is fixedly installed on one side of the tank body 1, a solvent injection pipe 7, an exhaust pipe 8, a rubber particle injection pipe 9 and a nitrogen injection pipe 10 are sequentially installed between the partition plate and the sealing cover 2, and a first solenoid valve 11 for controlling the pipeline switch is provided in the middle of the solvent injection pipe 7, the exhaust pipe 8, the rubber particle injection pipe 9 and the nitrogen injection pipe 10;

[0025] The bottom of the tank body 1 is connected to a second solenoid valve 12 for discharging. Considering that the existing device only dissolves the rubber by shaking during the rubber dissolution process, it is not easy for the solvent to be mixed into the rubber, which will affect the effect of rubber dissolution. The device drives the multiple stirring components and the vibration component through the reduction motor 5 to fully mix the solvent and the rubber particles. When the reduction motor 5 is turned on, the output shaft of the reduction motor 5 drives the triangular bracket 14 to rotate. During the rotation of the triangular bracket 14, the main stirring rod and the long stirring blade 19 will be used for the main mixing point. At the same time, the auxiliary stirring rod will be gear-driven with the gear ring 18 on the inner wall of the tank body 1 through the transmission gear 17. At this time, three auxiliary mixing points will be added, so that the solvent and the rubber particles can be fully mixed. In addition, considering the presence of a mixing blind spot at the bottom of the tank body 1, the solvent or rubber particles in the mixing blind spot of the tank body 1 will be vibrated by the vibration component, so that the rubber particles deposited at the bottom of the tank body 1 can be brought to the mixing area by the vibration for re-mixing.

[0026] The multiple stirring assembly includes a main stirring rod 13, a triangular bracket 14, an auxiliary stirring rod 15, a transmission gear 17 and a gear ring 18. The upper and lower ends of the main stirring rod 13 are fixedly installed with triangular brackets 14, and multiple auxiliary stirring rods 15 are rotatably connected between the two triangular brackets 14 through bearings, and the top of the upper triangular bracket 14 is fixed with a shaft 16 connected to the coupling. The upper and lower ends of the multiple auxiliary stirring rods 15 are fixedly sleeved with transmission gears 17, and each transmission gear 17 is meshed with the gear ring 18. The two gear rings 18 are fixedly installed in the middle of the tank body 1. By arranging the transmission gear 17 to cooperate with the gear ring 18, several more stirring pads are added to the device during the stirring process, so that the mixing efficiency is improved. During the mixing process, three auxiliary stirring rods will be used to cooperate with the main stirring rod for sufficient mixing.

[0027] Long stirring blades 19 are evenly distributed on the outside of the main stirring rod 13, and short stirring blades 20 are evenly distributed on the outside of the auxiliary stirring rod 15, and the long stirring blades 19 and the short stirring blades 20 are staggered. By arranging the long stirring blades 19 and the short stirring blades 20 in a cross-type distribution, the dissolved liquid and the rubber particles will be stirred and mixed between the long stirring blades 19 and the short stirring blades 20 during stirring, and the uniformity is high.

[0028] The length of the short stirring blade 20 is less than the length of the annular portion of the gear ring 18. The above design avoids the friction between the short stirring blade 20 and the tank body 1 or directly causes the gear transmission to get stuck.

[0029] The multiple vibration components all include a driving end 21, a transmission rod 23, a mounting sleeve 24, a spring 25 and a vibration end 26. A vibration motor 22 is installed inside the driving end 21, and a transmission rod 23 is fixedly installed on the upper end of the driving end 21. The outer sleeve of the transmission rod 23 is provided with a mounting sleeve 24. Springs 25 are evenly distributed on the outer surface of the mounting sleeve 24, and a vibration end 26 is fixed at the other end of each spring 25. By arranging the vibration components, the vibration mixing is assisted at the blind spots that cannot be stirred by the multiple stirring components, thereby improving the mixing efficiency of the device between the rubber block particles and the solvent.

[0030] The outer sleeve of the transmission rod 23 is provided with a flexible buffer 27, and the flexible buffer 27 is installed in the reserved hole opened at the bottom of the tank body 1. By setting the flexible buffer 27, the protective effect of the contact surface between the transmission rod 23 and the reserved hole of the tank body 1 is removed, thereby avoiding the rigid contact between the surface of the transmission rod 23 and the reserved inner wall of the tank body 1 to produce a wound surface. The flexible buffer 27 is made of a material that does not react with the dissolution process.

[0031] The upper middle side of the exhaust pipe 8 is also connected to the air filter box 28, and multiple screens 29 are evenly distributed inside the air filter box 28, and activated carbon adsorption blocks 30 are placed between the multiple screens 29, and an air filter element 31 is placed on the upper end of the uppermost screen 29. The lower middle side of the exhaust pipe 8 is also connected to an air duct, and a barometer 32 for detecting the internal pressure of the tank body 1 is installed at the upper end of the air duct. The barometer 32 is provided to detect the internal air pressure of the tank body 1 during the dissolution reaction. When the air pressure is abnormal, the gas will be discharged through the first solenoid valve 11, and the discharged gas will be filtered by the activated carbon adsorption block 30 and the air filter element 31. When the air pressure inside the tank body 1 is too low, the nitrogen injection pipe 10 will be started to inject nitrogen into the tank body 1.

[0032] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
