Description

Technical Field

[0001] The utility model belongs to the technical field of mixers, and more particularly to a powder material mixing and coating machine. Background Art

[0002] Mixing and coating machines are mainly used for mixing and dispersing materials, and have a high-temperature heating function, which can make the materials fully heated, increase the contact area of the materials, and make the material coating more uniform. Mixing and coating machines have a wide range of uses, such as functions of mixing, dispersing, crushing, drying, granulating and coating of slurries and powders. This equipment is widely used in the fields of new energy materials, medicine, coatings, etc.

[0003] Carbon coating is one of the most common material modification methods. When coating carbon powder, carbon powder and coating pitch need to be added into the mixing and coating machine and heated to a specified temperature to melt the coating pitch. Through high-speed stirring and mixing by the mixing and coating machine, the asphalt material can be evenly coated on the surface of the carbon powder. In the prior art, rubber seals are generally used to seal the main shaft of the mixing and coating machine. However, during the working process of the mixing and coating machine, the heating temperature is relatively high. Therefore, after long-term use, it is easy to accelerate the aging of the rubber seals, which is likely to cause deviation when the main shaft rotates, resulting in deformation, thus reducing the service life of the mixing and coating machine.

[0036] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the utility model.

[0037] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the referred components or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the utility model.

[0038] Please refer toFigures 1-7 As shown in the figure, the utility model relates to a powder material mixing and coating machine, which includes a support arm 1;

[0039] A driving component 2, a transmission component 3, a coating component 4, a sealing component 5 and an adjusting component 6 are respectively arranged on the support arm 1;

[0040] The transmission component 3 is fixedly installed inside the output end of the driving component 2 so that the driving component 2 drives the transmission component 3 to rotate;

[0041] The coating component 4 is fixedly installed on the outer surface of the transmission component 3 so that the driving component 2 drives the coating component 4 to operate through the transmission component 3;

[0042] The sealing component 5 is fixedly installed on the outer surface of the coating component 4 to be used for sealing the coating component 4;

[0043] One side of the adjusting component 6 is fixedly connected to the outer surface of the sealing component 5 to be used for adjusting the pressure compensation of the sealing component 5.

[0044] During use, toner and coating asphalt are added into the coating component 4 and heated to a specified temperature. At the same time, an external cooling water pipe is fixedly installed at both ends of the sealing component 5, so that the coolant can enter the sealing component 5. By starting the driving component 2 to drive the transmission component 3 fixedly installed at its output end to rotate, when the transmission component 3 rotates, it can drive the coating component 4 fixedly installed inside it to rotate, thus facilitating the mixing and stirring of the toner and coating asphalt inside it. When the coating component 4 rotates, it can drive the sealing component 5 fixedly installed on its outer surface to rotate. Since the sealing component 5 is a mechanical seal structure, during its rotation, it is easy to generate relatively high heat. Therefore, it is necessary to pass an external coolant to make it flow inside the sealing component 5, so as to facilitate cooling of its friction position and lubricate its rigid connection position. By changing the rotation speed of the coating component 4 driven by the driving component 2 in cooperation with the transmission component 3, the adjusting component 6 can be rotated to change the pressure compensation of the sealing component 5 itself, thereby facilitating the change of the friction force of the sealing component 5 itself, and improving the use effect of the sealing component 5.

[0045] The utility model drives the transmission component 3 to rotate by starting the driving component 2. The transmission component 3 can drive the coating component 4 to rotate, and the coating component 4 can drive the sealing component 5 to rotate. Since the sealing component 5 is a mechanical seal structure, during its rotation process, relatively high heat is easily generated. Therefore, it is necessary to connect external coolant to flow inside the sealing component 5, so as to facilitate cooling of its friction position and lubricate its rigid connection position at the same time. By driving the coating component 4 to rotate at different speeds through the cooperation of the driving component 2 and the transmission component 3, the rotation adjustment component 6 can be used to change the pressure compensation of the sealing component 5 itself, thereby facilitating the change of the friction force of the sealing component 5 itself, avoiding large wear of the sealing component 5 after long-term use, and improving the service life of the powder material mixing and coating machine.

[0046] In one embodiment, for the above-mentioned driving component 2, the driving component 2 includes a fixing frame 201. One side of the fixing frame 201 is fixedly installed with one side of the support arm 1, and a motor 202 is fixedly installed on one side of the fixing frame 201. The output end of the motor 202 is fixedly installed inside the transmission component 3.

[0047] By starting the motor 202 to drive the transmission component 3 fixedly installed at its output end to rotate, stable power is provided for the transmission component 3.

[0048] In one embodiment, for the above-mentioned transmission component 3, the transmission component 3 includes a main transmission wheel 301. The inside of the main transmission wheel 301 is fixedly installed with the output end of the motor 202. A transmission belt 302 is arranged inside the main transmission wheel 301 in a transmission manner, and a secondary transmission wheel 303 is arranged inside the transmission belt 302 in a transmission manner. The inside of the secondary transmission wheel 303 is fixedly installed on the outer surface of the coating component 4.

[0049] By starting the motor 202 to drive the main transmission wheel 301 fixedly installed at its output end to rotate, since the main transmission wheel 301 and the secondary transmission wheel 303 are connected by a transmission belt 302 in a transmission manner, when the main transmission wheel 301 rotates, it can cooperate with the transmission belt 302 to drive the secondary transmission wheel 303 to rotate, and then drive the coating component 4 fixedly installed inside to operate, thereby providing stable power for the coating component 4.

[0050] In one embodiment, for the above-mentioned coating component 4, the coating component 4 includes a mixing tank 401. The top of the mixing tank 401 is fixedly installed with the bottom end of the support arm 1. A stirring rod 402 is rotatably arranged inside the mixing tank 401. The outer surface of the stirring rod 402 is fixedly installed on the inner wall of the sealing component 5, and the outer surface of the stirring rod 402 is fixedly installed inside the secondary transmission wheel 303;

[0051] A feeding pipe 403 is fixedly connected to the top end of the mixing box 401, a discharging pipe 404 is fixedly connected to the bottom end of the mixing box 401, and a ball valve 405 is fixedly installed inside the discharging pipe 404.

[0052] When the secondary driving wheel 303 rotates, it can drive the stirring rod 402 fixedly installed inside it to rotate, so as to stir and mix the raw materials inside the mixing box 401. The powdery raw materials to be processed are poured into the mixing box 401 through the feeding pipe 403, so that it is convenient to stir them by the stirring rod 402. When the processing is completed, by opening the ball valve 405, the inside of the discharging pipe 404 is communicated with the inside of the mixing box 401, and then the processed powdery materials can flow out through the discharging pipe 404, which is more convenient.

[0053] In one embodiment, for the above-mentioned sealing assembly 5, the sealing assembly 5 includes a housing 501, the outer surface of the housing 501 is fixedly installed inside the support arm 1, a support frame 502 is fixedly installed at the top end of the housing 501, a sealing cylinder 503 is rotatably arranged inside the support frame 502, and the inner wall of the sealing cylinder 503 is fixedly installed with the outer surface of the stirring rod 402;

[0054] A liquid inlet 504 is formed on one side of the housing 501, a liquid inlet joint 505 is fixedly installed inside the liquid inlet 504, a liquid outlet 506 is formed on the other side of the housing 501, and a liquid outlet joint 507 is fixedly installed inside the liquid outlet 506.

[0055] When the stirring rod 402 rotates along with the rotation of the secondary driving wheel 303, it can drive the sealing cylinder 503 fixedly installed on its outer surface to rotate. Since the outer surface of the sealing cylinder 503 is fitted with the top end of the support frame 502, when the sealing cylinder 503 rotates, it can rub against the top end of the support frame 502. Then, when the coolant enters the inside of the housing 501 through the liquid inlet joint 505, it can wrap the outer surface of the sealing cylinder 503, absorb the heat generated by the friction between the sealing cylinder 503 and the support frame 502, and lubricate between the sealing cylinder 503 and the support frame 502 at the same time. The coolant after absorbing the heat can flow out from the inside of the liquid outlet joint 507, so as to form a cycle, improving the cooling effect of the powder material mixing and coating machine.

[0056] In one embodiment, for the above-mentioned adjusting component 6, the adjusting component 6 includes a sealing block 601. The sealing block 601 is arranged inside the housing 501. A threaded rod 602 is slidably arranged inside the sealing block 601. A rotating seat 603 is threadedly connected to the outer surface of the threaded rod 602. One side of the rotating seat 603 is fixedly installed with one side of the support arm 1. A threaded cylinder 604 is threadedly connected to the threaded surface of the threaded rod 602. One end of the threaded cylinder 604 is fixedly connected with a wedge-shaped block 605;

[0057] A limiting groove 606 is formed inside the housing 501. A limiting block 607 is slidably arranged inside the limiting groove 606. One side of the limiting block 607 is fixedly connected to the outer surface of the threaded cylinder 604.

[0058] By rotating the threaded rod 602 to drive the threaded cylinder 604 threadedly connected to its threaded surface to move, since the limiting block 607 is fixedly connected to the outer surface of the threaded cylinder 604 and the outer surface of the limiting block 607 is slidably arranged inside the limiting groove 606, when the threaded cylinder 604 moves, it can drive the limiting block 607 to move along the direction of the limiting groove 606. When the threaded cylinder 604 moves, it can drive the wedge-shaped block 605 fixedly connected to one end of it to move. The arrangement of the limiting block 607 and the limiting groove 606 can limit the position of the threaded cylinder 604, thereby preventing it from rotating as the threaded rod 602 rotates, and thus improving the stability of the threaded cylinder 604 during the moving process.

[0059] In one embodiment, for the above-mentioned adjusting component 6, the adjusting component 6 further includes a spring 608. One end of the spring 608 is fixedly connected to the outer surface of the sealing cylinder 503. One end of the spring 608 is fixedly connected with a conical block 609. A key groove 610 is formed inside the conical block 609. A connecting key 611 is slidably arranged inside the key groove 610. One side of the connecting key 611 is fixedly connected to the outer surface of the sealing cylinder 503.

[0060] When the wedge block 605 moves along with the movement of the threaded barrel 604, it can drive the tapered block 609 arranged in contact with one side of it to move. When the tapered block 609 moves, it can squeeze the spring 608 fixedly connected to one side of it. When the spring 608 is compressed, its elastic force can act on the outer surface of the sealing cylinder 503 fixedly connected to one end of it, thereby increasing the pressure between the sealing cylinder 503 and the support frame 502, facilitating the adjustment of its pressure compensation. The keyway 610 and the connection key 611 are arranged so that the sealing cylinder 503 can drive the tapered block 609 to rotate during the rotation process. Since one side of the tapered block 609 is in contact with one side of the wedge block 605 and the friction between them can be reduced under the action of the coolant, the extrusion force of the wedge block 605 can always act on one side of the tapered block 609.

[0061] Through the above technical solutions: 1. By starting the driving component 2 to drive the transmission component 3 to rotate, the transmission component 3 can drive the covering component 4 to rotate, and the covering component 4 can drive the sealing component 5 to rotate. Since the sealing component 5 is a mechanical seal structure, during its rotation process, relatively high heat is likely to be generated. Therefore, it is necessary to introduce external coolant to flow inside the sealing component 5, facilitating the cooling of its friction position and lubricating its rigid connection position at the same time. By setting different rotation speeds of the driving component 2 and the transmission component 3 to drive the covering component 4 to rotate, the rotation adjustment component 6 can be rotated to change the pressure compensation of the sealing component 5 itself, thereby facilitating the change of the friction force of the sealing component 5 itself, avoiding significant wear of the sealing component 5 after long-term use, and improving the service life of the powder material mixing and coating machine.

[0062] 2. By rotating the threaded rod 602 to drive the threaded barrel 604 threadedly connected to its threaded surface to move, the threaded barrel 604 drives the wedge block 605 to move. The wedge block 605 can drive the tapered block 609 arranged in contact with one side of it to move. When the tapered block 609 moves, it can squeeze the spring 608 fixedly connected to one side of it. When the spring 608 is compressed, its elastic force can act on the outer surface of the sealing cylinder 503 fixedly connected to one end of it, thereby increasing the pressure between the sealing cylinder 503 and the support frame 502, facilitating the adjustment of its pressure compensation.
