Description

Technical Field

[0001] The utility model relates to the technical field of carbon products, in particular to a paving device. Background Art

[0002] In the production process of carbon products, the uniform laying of paste has a crucial effect on the quality of the final product. However, traditional paste laying methods often rely on manual operation, which is not only inefficient but also difficult to ensure the uniformity and consistency of laying. Especially on large-scale and continuous production lines, this problem is more prominent.

[0003] With the development of mechanical automation technology, many industries have begun to try to use mechanical equipment to replace manual labor for material laying. However, in the field of carbon product production, due to the special properties of the paste (such as viscosity, fluidity, etc.) and the complexity of the production environment (such as temperature, humidity, etc.), it has become particularly important to develop an efficient and reliable paste leveling and paving device for carbon products.

[0004] For example, the Chinese utility model patent (CN208432299U) discloses a rake position monitoring device for a thickener, which solves the following problems: The traditional height displacement sensor is installed inside the support cylinder of the elevator, and the telescopic rod installed inside the plexiglass shield moves up and down to output signals to the programmable controller to realize digital display on the instrument and visually observe the position of the telescopic rod inside the plexiglass shield on site to observe the operating height of the rake. However, in actual use, the plexiglass shield is often damaged due to the negligence of the operator, resulting in damage to the height displacement sensor.

[0005] The device includes a square iron cover, a height displacement sensor, a circular guiding iron cylinder, a sliding rod, a base, an anti-rotation block, and an anti-rotation block track. The base is placed horizontally, the anti-rotation block track is located below the base and perpendicular to the base. One end of the anti-rotation block track is fixed on the lower surface of the base. The anti-rotation block is located on the anti-rotation block track. The height displacement sensor has a head end and a tail end in the vertical direction. The head end has a telescopic rod that can move up and down. The telescopic rod vertically passes through the base and is fixed to the anti-rotation block. The square iron cover covers the height displacement sensor and is fixed on the base. The sliding rod is located outside the square iron cover. The sliding rod vertically passes through the base and can slide up and down. The sliding rod includes a first end above the base and a second end below the base. The second end is fixedly connected to the anti-rotation block. There is an opening on the side wall of the circular guiding iron cylinder. The circular guiding iron cylinder covers the sliding rod and is fixed on the base.

[0006] When using the above-mentioned technology, the following technical problems are found in the existing technology: The device does not have a suitable positioning structure, which makes it difficult to accurately control the laying position during operation, resulting in the offset of the paste laying, affecting the product quality and the smooth progress of the subsequent production process. Therefore, we design a paving device to provide another technical solution to the above technical problems. Utility Model Content

[0040] Through the design of the spreading structure, the device can effectively distribute the paste evenly in the required area, ensuring precise control of the paving thickness.

[0041] The usage process of a paving device provided by the present utility model is as follows: The user puts the paste material into the interior of the mold box 1, and then powers on the first motor 6 to rotate. The output end of the first motor 6 drives the transverse screw rod 7 to rotate. Since the outer side of the transverse screw rod 7 is threadedly connected with the first moving block 8, the rotation of the transverse screw rod 7 drives the first moving block 8 to slide at the bottom of the top plate 4. Then the user powers on the second motor 10 to rotate. The output end of the second motor 10 drives the longitudinal screw rod 11 to rotate. Since the outer side of the longitudinal screw rod 11 is threadedly connected with the second moving block 12, the rotation of the longitudinal screw rod 11 drives the second moving block 12 to slide at the bottom of the connecting plate 9. The user powers on the hydraulic cylinder 13, and the output end of the hydraulic cylinder 13 drives the connecting rod 14 to lift and lower, so as to be able to position the mounting plate 15, ensuring that the device is accurately positioned at the preset paving position during operation, reducing position deviation, and ensuring the accuracy and consistency of the paste material paving; The device powers on the first motor 6 to rotate, and thus can drive the roller 37 to pave the paste material inside the mold box 1. When it is necessary to adjust the angle of the roller 37, the user powers on the fourth motor 29 to rotate. The output end of the fourth motor 29 drives the worm 30 to rotate. Since one side of the worm 30 is meshed with the worm gear 31, the rotation of the worm 30 drives the worm gear 31 to rotate, and thus can adjust the angles of the rotating column 32 and the fixed column 33, and at the same time adjust the angle of the roller 37. When leveling the paste material, the user powers on the third motor 17 to rotate. The output end of the third motor 17 drives the first bevel gear 18 to rotate. Since the top of the first bevel gear 18 is meshed with the second bevel gear 19, and the bottom of the first bevel gear 18 is meshed with the third bevel gear 20, the rotation of the first bevel gear 18 can drive the second bevel gear 19 and the third bevel gear 20 to rotate in opposite directions, and thus can drive the first turntable 25 and the second turntable 26 to rotate in opposite directions. The design of the two reverse rotating wheels can ensure that during the paving process, the material is evenly distributed on the working surface. Since the two rotating wheels rotate in opposite directions, they can cancel out the centrifugal force generated by the rotation with each other, thereby avoiding uneven accumulation or missing of the material during the paving process; In summary, the present utility model will significantly improve production efficiency, reduce costs, improve product quality, and enhance the stability and adaptability of the equipment.
