Description

Technical Field

[0001] This utility model belongs to the field of metal-impregnated carbon graphite production technology, specifically relating to a rolling device for metal-impregnated carbon graphite production. Background Technology

[0002] Metal-impregnated carbon graphite is a special composite material made by impregnating metals such as silver, copper, and lead into the pores of graphite. This material combines the excellent properties of graphite and metals, and has advantages such as good electrical and thermal conductivity, high mechanical strength, wear resistance, and air impermeability. It has wide applications in electrical appliances, mechanical seals, and lubrication.

[0003] Currently, the production process of metal-impregnated carbon graphite mainly includes raw material preparation, molding, carbonization, impregnation, and graphitization. Raw material preparation specifically includes steps such as raw material selection, proportioning, mixing, kneading, rolling, crushing, and sieving. In the rolling process, the rolling mill mainly consists of two opposing rotating rollers. Graphite paste falls from a feed hopper above the rollers into the gap between the two rollers, where it is rolled into sheets under the pressure of the rollers and then falls into a receiving hopper below the rollers. However, in actual production, the gap between the two rollers is fixed and cannot be flexibly adjusted according to the required sheet thickness, limiting its use. Furthermore, there is a problem of material sticking to the rollers; if not cleaned promptly, it can easily cause blockages and shutdowns, requiring improvement. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a rolling mill device for the production of metal-impregnated carbon graphite, which can flexibly adjust the distance between the two rolls and clean the rolls in a timely manner, so as to solve the above problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sheet rolling device for producing metal-impregnated carbon graphite, comprising a machine base, a first double-rod hydraulic cylinder horizontally arranged in the left-right direction is fixedly mounted at the center of the bottom of the machine base, both piston rods of the first double-rod hydraulic cylinder are fixedly connected to a movable seat, the top of the movable seat is slidably connected to the bottom of the machine base, and the bottom end is fixedly connected to a support plate, both support plates are fixedly mounted with motors through in the front-back direction, the output shafts of both motors are facing forward and are detachably connected to rollers, scrapers are abutted on the opposite sides of the two rollers, the rear end of the scraper is fixedly connected to the housing of the adjacent motor, a discharge bin is provided above the gap between the two rollers, a receiving frame is provided below the two rollers, and partitions are provided on the left and right sides of the receiving frame, the two partitions dividing the receiving frame into a sheet groove in the middle and scraper grooves on the left and right sides.

[0006] Preferably, a T-shaped slider is fixedly connected to the top of the movable base, and a T-shaped groove adapted to the slider is opened on the bottom of the base corresponding to the slider along the left and right direction, and the slider is slidably disposed on the corresponding groove.

[0007] Preferably, a second double-rod hydraulic cylinder is radially fixedly mounted on the front end of the motor's output shaft. Both piston rods of the second double-rod hydraulic cylinder are fixedly connected to a square locking frame. A mounting box is fixedly connected to the front end of the motor's output shaft. The front end of the mounting box is open. A mounting block is fixedly connected to the rear end of the roller. The mounting block is inserted into the mounting box. The locking frame is fitted onto the outside of the mounting box and the mounting block.

[0008] Preferably, the mounting block is adapted to the corresponding mounting box.

[0009] Preferably, the locking frame is adapted to the mounting box.

[0010] Preferably, the rear end of the scraper is fixedly connected to the housing of the corresponding motor via an L-shaped connecting plate.

[0011] The beneficial effects of this invention are as follows: During sheet rolling, graphite paste can be discharged from the discharge bin into the gap between the two rollers. Two motors drive the two rollers to rotate relative to each other. Under the squeezing action of the two rollers, the graphite paste is rolled into sheets, and the formed sheets fall into the sheet trough in the receiving frame. During the process, the scraper can effectively scrape and clean the rotating rollers, removing material adhering to the rollers in a timely manner, avoiding adverse effects on subsequent sheet rolling, preventing blockages and shutdowns, and facilitating the long-term smooth operation of sheet rolling and improving sheet quality. The scraped material can be received by the corresponding scraper trough. When the required sheet thickness changes, the first double-rod hydraulic cylinder can be activated after the machine stops. Through the extension and retraction of the two piston rods on it, the two moving blocks can be moved relative to or away from each other, thereby bringing the two rollers closer or further apart. This achieves flexible adjustment of the gap between the two rollers, meeting the rolling needs of various different sheets, with a wide range of applications and more flexible and convenient overall use. In addition, the detachable connection between the roll and the output shaft of the corresponding motor makes it easy to disassemble and replace the roll when problems occur, making the whole device more flexible and practical.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1 to 7 As shown, a sheet rolling device for producing metal-impregnated carbon graphite includes a base 1. A first double-rod hydraulic cylinder 2 is horizontally arranged in the left-right direction and fixedly mounted at the center of the bottom of the base 1. The two piston rods of the first double-rod hydraulic cylinder 2 are fixedly connected to a movable seat 3. The top of the movable seat 3 is slidably connected to the bottom of the base 1, and the bottom is fixedly connected to a support plate 4. Motors 5 are fixedly mounted through the two support plates 4 in the front-back direction. The output shafts of the two motors 5 are both facing forward and detachably connected to rollers 6. Scrapers 7 are abutted on the opposite sides of the two rollers 6. The rear end of the scraper 7 is fixedly connected to the housing of the adjacent motor 5. A discharge bin 8 is provided above the gap between the two rollers 6. A receiving frame 9 is provided below the two rollers 6. Partitions 10 are provided on the left and right sides of the receiving frame 9. The two partitions 10 divide the receiving frame 9 into a sheet material groove 11 in the middle and scraper grooves 12 on the left and right sides.

[0022] During sheet rolling, graphite paste is fed through the discharge bin 8 into the gap between the two rollers 6. Two motors 5 drive the two rollers 6 to rotate relative to each other. Under the squeezing action of the two rollers 6, the graphite paste is rolled into sheets, and the formed sheets fall into the sheet trough 11 in the receiving frame 9. During the process, the scraper 7 can effectively scrape and clean the rotating rollers 6, removing the material adhering to the rollers 6 in time, avoiding adverse effects on subsequent sheet rolling, preventing blockages and shutdowns, and facilitating the long-term smooth operation of sheet rolling and improving sheet quality. The scraped material can be received by the corresponding scraper trough 12. When the required sheet thickness changes, the first double-rod hydraulic cylinder 2 can be operated after the machine stops. Through the extension and retraction of the two piston rods on it, the two moving blocks 3 can be moved relative to or away from each other, thereby bringing the two rollers 6 closer or further apart. This allows for flexible adjustment of the gap between the two rollers 6, meeting the rolling needs of various different sheets, with a wide range of applications and more flexible and convenient overall use. In addition, the detachable connection between the roll 6 and the output shaft of the corresponding motor 5 makes it easy to disassemble and replace the roll 6 when problems occur, making the whole device more flexible and practical.

[0023] In this embodiment, a T-shaped slider 13 is fixedly connected to the top of the movable base 3. A T-shaped groove 14 adapted to the slider 13 is provided on the bottom of the machine base 1 along the left and right direction. The slider 13 is slidably disposed on the corresponding groove 14 to effectively guide and limit the movement of the movable block 3, and to ensure smooth and flexible adjustment of the gap between the two rollers 6.

[0024] In this embodiment, a second double-rod hydraulic cylinder 15 is radially fixedly mounted on the front end of the output shaft of the motor 5. Both piston rods of the second double-rod hydraulic cylinder 15 are fixedly connected to square locking frames 16. An installation box 17 is fixedly connected to the front end of the output shaft of the motor 5. The front end of the installation box 17 is open. An installation block 18 is fixedly connected to the rear end of the roll 6. The installation block 18 is inserted into the installation box 17. The locking frames 16 are fitted on the outside of the installation box 17 and the installation block 18. When the roll 6 needs to be replaced, the second double-rod hydraulic cylinder 15 can be started in the stopped state to extend its two piston rods and drive the two locking frames 16 to move in opposite directions until they are completely separated from the installation box 17. This releases the locking of the installation block 18. Then, the installation block 18 can be pulled forward to remove the original roll 6. Next, after taking the new roll 6, first align the mounting block 18 on it with the mounting box 17 and insert it into place. Then, operate the second double-rod hydraulic cylinder 15 to retract its two piston rods, causing the two locking frames 16 to move relative to each other until the two locking frames 16 are fitted onto the outer ends of the mounting box 17 and the mounting block 18, locking the mounting block 18 in place. This completes the fixed installation of the new roll 6. In this way, the roll 6 can be easily disassembled and assembled, facilitating flexible replacement when the roll 6 malfunctions, making the overall device more flexible and practical.

[0025] In this embodiment, the mounting block 18 is adapted to the corresponding mounting box 17 to ensure that the mounting block 18 is smoothly inserted and installed in place.

[0026] In this embodiment, the locking frame 16 is adapted to the mounting box 17 to ensure that the locking frame 16 is smoothly fitted into place, thereby achieving the limiting and locking of the mounting block 18.

[0027] In this embodiment, the rear end of the scraper 7 is fixedly connected to the housing of the corresponding motor 5 via an L-shaped connecting plate 19 to fix the scraper 7 and cooperate to scrape and clean the material on the roller 6.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
