[0028] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0029] As Figures 1 to 4 shown, this embodiment proposes a pressurized internal mixer for processing rubber bearings, including

[0030] an equipment rack 1, a pair of machine bases 2, and a kneading bin 3. The machine bases 2 are both installed on the equipment rack 1, and the kneading bin 3 is installed between the machine bases 2;

[0031] a sealing assembly 4, which is arranged on the top of the equipment rack 1;

[0032] a feeding assembly 5, which is arranged outside the equipment rack 1;

[0033] The sealing assembly 4 includes a top rack 4-1, and the top rack 4-1 is rotatably connected to the top of the equipment rack 1 through a pin shaft. Connecting racks 4-2 are provided on the side surfaces of the equipment rack 1 and the outer surface of the top rack 4-1. A rotating block 4-3 is rotatably connected in the connecting rack 4-2 through a pin shaft. A telescopic hydraulic cylinder 4-4 is fixedly connected between the rotating blocks 4-3. An extension rack 4-5 is provided on the top of the top rack 4-1. A sealing hydraulic cylinder 4-6 is installed on the extension rack 4-5. The output end of the sealing hydraulic cylinder 4-6 is connected to a pair of fixed ears 4-7. A sealing seat 4-8 is fixedly connected between the fixed ears 4-7. A pair of notches 4-9 are opened at the top of the kneading bin 3. A pressing equipment 4-10 is installed on the top of the sealing seat 4-8. An air cavity 4-11 is opened in the sealing seat 4-8. A pair of grooves 4-12 are opened at the bottom of the sealing seat 4-8, and the grooves 4-12 communicate with the air cavity 4-11.

[0034] In this embodiment, in order to achieve the effect of being in a closed state and pressurized, a closing component 4 is designed. At the top of the equipment rack 1, a top rack 4-1 is rotatably connected by a pin shaft. Connecting frames 4-2 are fixed to the back surfaces of both the top rack 4-1 and the equipment rack 1. A rotating block 4-3 is rotatably connected in the connecting frame 4-2. A telescopic hydraulic cylinder 4-4 is connected between the rotating blocks 4-3. The backward rotation of the top rack 4-1 can be controlled by the telescopic movement of the telescopic hydraulic cylinder 4-4. Two extension frames 4-5 are arranged on the front surface of the top rack 4-1 and a closing hydraulic cylinder 4-6 is installed. The output end of the closing hydraulic cylinder 4-6 is connected with a fixed ear 4-7. A sealing seat 4-8 is fixed between the fixed ears 4-7. The sealing seat 4-8 can be used to enter the internal mixer bin 3 and be sealedly connected thereto. An air cavity 4-11 is opened in the sealing seat 4-8, and a groove 4-12 communicating with the air cavity 4-11 is opened at the bottom. A pressurizing device 4-10 is installed on the sealing seat 4-8. The pressure in the internal mixer bin 3 can be increased through the air cavity 4-11 and the groove 4-12 to improve the sealing effect.

[0035] Furthermore, the feeding component 5 includes a side port 5-1 which is opened on the side end face of the equipment rack 1. A fixed block 5-2 is installed in the side port 5-1. A telescopic cylinder 5-3 is arranged on the fixed block 5-2. The output end of the telescopic cylinder 5-3 is connected with a pushing rack 5-4. An outer groove 5-5 is opened on the outer surface of the equipment rack 1. A feeding hopper 5-6 is rotatably connected in the outer groove 5-5. One end of the rotating shaft of the feeding hopper 5-6 is provided with a transmission gear 5-7 which meshes with the pushing rack 5-4.

[0036] In this embodiment, in order to receive the rubber after internal mixing, a feeding component 5 is designed. A side port 5-1 is opened on the side surface of the equipment rack 1. A fixed block 5-2 is arranged in the side port 5-1 and a telescopic cylinder 5-3 is installed. The output end of the telescopic cylinder 5-3 is fixed with a pushing rack 5-4. The linear movement can be controlled by the telescopic cylinder 5-3. An outer groove 5-5 is opened on the outer surface of the equipment rack 1. A feeding hopper 5-6 is rotatably connected in the outer groove 5-5. One end of the rotating shaft of the feeding hopper 5-6 is provided with a transmission gear 5-7 which meshes with the pushing rack 5-4. The opening and closing state of the feeding hopper 5-6 can be controlled through the transmission between the pushing rack 5-4 and the transmission gear 5-7.

[0037] Furthermore, the notch 4-9 is located directly below the fixed ear 4-7, and the opening size of the notch 4-9 matches the size of the fixed ear 4-7.

[0038] In this embodiment, by opening the notch 4-9, the sealing seat 4-8 can be docked with the internal mixer bin 3 to improve the sealing effect of tight fitting.

[0039] Furthermore, the bottom of the sealing seat 4-8 is of an arc structure, and the sealing seat 4-8 is in sealed and fitted connection with the internal mixer bin 3.

[0040] In this embodiment, the arc-shaped structure does not affect the kneading effect and can increase the internal kneading space.

[0041] Furthermore, the top frame 4-1 can be controlled by the telescopic hydraulic cylinder 4-4 to flip backward by 90°.

[0042] In this embodiment, through the 90° flipping angle, the top frame 4-1 can be rotated backward, which is more convenient when filling materials into the kneading chamber 3.

[0043] Furthermore, the groove 4-12 is located at the highest position on the inner surface of the sealing seat 4-8.

[0044] In this embodiment, by arranging the groove 4-12 at the highest position on the surface of the sealing seat 4-8, it is avoided that the kneaded rubber enters the groove 4-12 and causes blockage.

[0045] Furthermore, the right-angle at the inner end face of the receiving hopper 5-6 is an inclined transition structure.

[0046] In this embodiment, by setting the right-angle inside the receiving hopper 5-6 as an inclined transition structure, it is convenient for the rubber to roll outwards and be taken out.

[0047] When kneading and processing are required, the materials are put into the kneading chamber 3. Then, the telescopic hydraulic cylinder 4-4 is started to push the top frame 4-1 to move upward, so that the sealing seat 4-8 is located directly above the kneading chamber 3. Subsequently, the closing hydraulic cylinder 4-6 is started to control the sealing seat 4-8 to move downward into the kneading chamber 3. After it is completely closed, the machine base 2 is started to conduct kneading. At the same time, the pressurizing device 4-10 is started, and pressure is applied to the kneading chamber 3 through the air cavity 4-11 and the groove 4-12 to increase the pressure while ensuring the sealing effect. After the kneading is completed, the air pressure is discharged. After the sealing seat 4-8 is opened and rotated outwards to discharge the rubber, the telescopic cylinder 5-3 is started at the same time to control the push rack 5-4 to drive the transmission gear 5-7, so that the receiving hopper 5-6 is flipped outwards and opened, and the rubber rolls into the receiving hopper 5-6. Then, the rubber can be taken away.

[0048] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
