Description

TECHNICAL FIELD

[0002] Plate roller is a key component for transferring graphic information in the printing industry, usually made of metal material, with precise graphics engraved on the surface. Its use is to cooperate with ink and printing material to stably and clearly print specific patterns and characters on various materials in processes such as rotary printing and intaglio printing. Due to the continuous adhesion and accumulation of ink during printing, impurities may also be mixed in. If not cleaned, the residual ink will dry on the surface of the plate roller, affecting the accuracy and color reproduction of subsequent printing, resulting in defects in the printed product. Therefore, the plate roller needs to be cleaned. The plate roller cleaned contains a large amount of water, if not dried, the water will not only rust the plate roller, but also dilute the ink added in subsequent printing, damage the performance of the ink, and greatly reduce the printing effect.

The inner wall of the gear ring 5 is engaged with the outer side of the plurality of transmission gears 6, and the rotation of the gear ring 5 drives the rotation of the transmission gears 6. A plurality of rack plates 7 are slidingly connected to the inside of the mounting disc 3. The outer side of the transmission gears 6 is engaged with the outer side of the rack plates 7, and the rotation of the transmission gears 6 uniformly transmits the power of the gear ring 5 to each rack plate 7, enabling the rack plate 7 to move synchronously in a straight line. The two ends of the plate roller column 4 are provided with a plurality of clamping grooves, and the outer wall of the rack plate 7 is detachably connected to the inside of the clamping groove. The rotation of the transmission gears 6 is converted into the linear motion of the rack plate 7, enabling the rack plate 7 to extend or retract from the mounting disc 3. When the rack plate 7 extends from the mounting disc 3, the outer wall of the rack plate 7 is detachably connected to the inside of the clamping groove, and through the cooperation of the rack plate 7 and the clamping groove, the firm connection between the plate roller column 4 and the mounting disc 3 is achieved.

The air extractor 11 is responsible for extracting the hot gas in the drying box 1, thereby creating conditions for subsequent heat recovery and reuse. The output end of the air extractor 11 is fixedly connected with a conveying pipe 12, which is used to convey the hot air extracted by the air extractor 11 to the subsequent structure for heat recovery operation. A plurality of air guide pipes 18 are fixedly connected to the two sides of the drying box 1, which are used to transmit hot air to the drying box 1 for drying operation. The other end of the plurality of air guide pipes 18 is fixedly connected with a heating box 17, which is used to heat the external air and transport it to the inside of the drying box 1 through the air guide pipe 18.

[0037] The heat recovery mechanism comprises a recovery tank 13, the bottom of which is fixedly connected to the top of the heating tank 17, and the recovery tank 13 is used to recover and reuse the heat contained in the dried gas, thereby saving energy consumption. The top of the recovery tank 13 is fixedly connected to the other end of the conveying pipe 12, and the inner wall of the middle part of the recovery tank 13 is fixedly connected with a partition plate 14, which is used to divide the recovery tank 13 into two parts, so as to guide the flow path of hot air and cold air in the recovery tank 13, so that they can fully exchange heat. The two ends of the partition plate 14 are respectively fixedly connected with a plurality of heat-conducting fins 15, which are in the shape of a wave, thereby increasing the contact area with the gas to improve the heat exchange efficiency. When the hot air and the cold air flow through the fins, a turbulent flow can be formed along the complex surface of the fins, increasing the contact area and contact time of the gas with the fins, greatly improving the rate of heat exchange, and preliminarily heating the cold air with the hot air, thereby improving the subsequent heating efficiency and saving overall energy consumption. The top of the recovery tank 13 is fixedly connected with a filter plate 16, which is used to filter the cold air entering from the outside, so as to block the particles such as dust and impurities in the outside air from entering the inside of the recovery tank 13 and the drying tank 1. An exhaust port is provided on the outside of the recovery tank 13 for the exhaust gas after heat exchange to be discharged, so as to create conditions for the new hot air and cold air to enter the recovery tank 13 for heat exchange.

[0038] Working principle: when the plate roller column 4 needs to be installed, first insert the plate roller column 4 between the two installation discs 3, then rotate the drive column 10, the drive column 10 drives the sliding ring 9 to slide on the top of the installation disc 3, the sliding of the sliding ring 9 drives the plurality of transmission columns 8 to rotate synchronously, the transmission columns 8 transmit the motion to the gear ring 5 to make it rotate, thereby the rotation of the gear ring 5 drives the transmission gear 6 to rotate, and then the rotation power of the gear ring 5 is uniformly transmitted to each rack plate 7, so that the rack plate 7 makes synchronous linear motion to extend out of the installation disc 3, and the plurality of clamping grooves on both ends of the plate roller column 4 are detachably connected with the outer wall of the extended rack plate 7, realizing the firm connection of the plate roller column 4 and the installation disc 3; when the plate roller column 4 needs to be disassembled, the drive column 10 is reversely rotated to drive the sliding ring 9 to slide reversely, the gear ring 5 is reversely rotated through the transmission column 8, the transmission gear 6 is reversely rotated to drive the rack plate 7 to retract into the installation disc 3, so that the rack plate 7 is separated from the clamping grooves of the plate roller column 4, realizing the convenient disassembly of the plate roller column 4. When the installation is completed, the motor 2 is turned on, the motor 2 operates to drive the installation disc 3 to rotate, thereby driving the plate roller column 4 to rotate synchronously, so that the drying is more uniform.

[0039] In the drying process, the waste gas with certain heat in the drying box 1 is extracted by two exhaust fans 11, and the hot air is transported to the recovery box 13 through the conveying pipe 12. The hot air entering the recovery box 13 exchanges heat with the cold air absorbed from the top of the recovery box 13 under the guidance of the partition 14, so as to preliminarily heat the cold air. The wave-shaped heat-conducting fins 15 at both ends of the partition 14 make the hot air and the cold air form turbulent flow when flowing, increase the contact area and time, and improve the heat exchange rate, so as to realize heat recovery and reuse. The heated cold air enters the heating box 17 for secondary heating, so as to more easily reach a higher temperature, thereby improving the heating efficiency. The cold air from the outside is filtered by the filter plate 16 to prevent dust and impurities from entering the recovery box 13 and the drying box 1. The exhaust gas after heat exchange is discharged in time through the exhaust port outside the recovery box 13, so as to drive new hot air and cold air into the recovery box 13 for continuous heat exchange, so as to realize heat recovery and reuse of the waste gas and save the overall energy consumption.

[0040] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it can still be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
