Description

Technical Field

[0001] The utility model relates to the technical field of transfer paper coating machinery, and specifically relates to a coating machine. Background Art

[0002] Generally, specific materials need to be coated on the surface of digital transfer paper. These materials are mainly used to improve the ink adhesion of the paper, the printing effect, and meet the requirements of digital transfer technology. The specific coated materials may vary depending on different application scenarios and printing requirements. For example, an ink-absorbing coating is coated onto the transfer paper through a coating machine to improve the paper's ink absorption ability and ensure that the ink can be evenly and quickly absorbed by the paper during printing.

[0003] When digital transfer paper is coated, it is conveyed into the coating machine through conveying rollers. The coating roller inside the coating machine coats the adhered coating onto the paper surface, and then the drying structure inside the coating machine blows warm air onto the paper coated with the coating to facilitate drying and shaping the coated paper.

[0004] Although the coating can be dried under the blowing of warm air, the warm air will also disperse the coating odor volatilized from the coating to the surrounding of the coating machine. Most drying structures of coating machines lack structures for treating coating odors, which is not conducive to ensuring the freshness and cleanliness of the air around the coating environment. Moreover, during the long-term storage of the coating in the storage tank for containing the coating, the coating is prone to precipitation, which is not conducive to directly pumping it to the position of the coating roller for use. Content of the Utility Model

[0005] The purpose of the utility model is to provide a coating machine to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

Then, the warm air blows towards the paper from the air drying port at the bottom of the drying box, facilitating the use of warm air to dry and shape the coating on the paper surface. At the same time, an external air pump sucks air through the exhaust pipe, causing the warm air for drying the coating to be exhausted from the other end of the drying box through the first air collecting hood. The air with coating odor exhausted is transported to an air purifier for purification treatment and then released, preventing the warm air with coating odor from diffusing into the coating environment to a certain extent and being conducive to ensuring the freshness and cleanliness of the air in the coating environment.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0034] Embodiment 1.

[0035] Specifically, an air drying box 440 is arranged at the top of the transfer paper, the air drying port 441 at the bottom of the air drying box 440 faces the transfer paper, and the two ends of the air drying box 440 are respectively communicated with the air inlet pipe 410 and the air extraction pipe 420. The air inlet pipe 410 blows warm air into the air drying box 440 to dry the coating on the paper, and the air extraction pipe 420 is used to suck the warm air mixed with the coating smell, so that the air drying box 440 can not only air-dry the coating but also directionally collect and purify the air flow for drying, preventing the warm air with the coating smell from diffusing into the coating environment to a certain extent, which is beneficial to ensuring the freshness and cleanliness of the air in the coating environment. During the process of the air inlet pipe 410 conveying warm air, the warm air drives the fan blades 612 at the bottom end of the shaft rod 610 to rotate, and the fan blades 612 drive a plurality of stirring paddles 611 on the shaft rod 610 to rotate and stir the coating, effectively preventing the coating from precipitating.

One end of the hose 520 is fixedly connected with a main pipe 530, and a plurality of L-shaped branch pipes 540 are uniformly and fixedly connected to the outside of the main pipe 530.

[0039] In this embodiment, the paint pump 510 sucks and conveys the paint inside the storage cylinder 600 through the hose 520 into the main pipe 530, and then dispersedly conveys it from the main pipe 530 to the branch pipes 540. The branch pipes 540 are fixed on the U-shaped frame 310, and the pipe orifices face the top of the coating roller 320. The branch pipes 540 convey the paint to the coating roller 320, and the coating roller 320 rotates to coat the paint on the transfer paper. A circular plate is detachably fixed to the top of the storage cylinder 600, and opening the circular plate facilitates injecting paint into the storage cylinder 600.

A first air collecting hood 421 is fixedly connected between the air extraction pipe 420 and the air drying box 440. An air drying opening 441 is formed in the bottom surface of the air drying box 440.

[0041] In this embodiment, an air suction pump conveys the warm air flow containing paint odor into the air purifier for purification treatment to prevent the air with paint odor from diffusing into the surrounding environment of the coating. Both the air suction pump and the air purifier are devices of the prior art, and their specific working principles will not be elaborated.

[0042] As Figure 4 shown, in this embodiment, the air inlet pipe 410 is fixedly connected to the air outlet end of an external warm air blower through a pipeline.

The bottom end of the air storage tank 430 is fixedly connected to a second air collecting hood 431, and the second air collecting hood 431 is fixedly connected to one end of a drying box 440.

[0043] In this embodiment, the warm air blower conveys warm air to the air storage tank 430 and the second air collecting hood 431. The warm air blows towards the paper through the drying openings 441 on the drying box 440, which is used to dry and shape the transfer paper. The warm air blower is a component of the prior art, and its specific working principle will not be elaborated.

[0044] As Figure 5 shown, in this embodiment, a fan blade 612 is fixed to the bottom end of a shaft rod 610. The fan blade 612 is arranged inside the air storage tank 430. During the process when the warm air flow passes through the fan blade 612, the fan blade 612 will drive the shaft rod 610 to rotate, and the shaft rod 610 drives the stirring paddle 611 to stir the paint to prevent the paint inside the storage barrel 600 from settling.

[0045] As Figure 2 shown, in this embodiment, the transfer paper is conveyed onto the pallet 210 inside the coater. The coating roller 320 contacts the transfer paper and rotates along with the coating roller 320 to coat the paint onto the transfer paper.

[0049] In this embodiment, when encountering a transfer paper with a narrow width, the motor 340 can be driven by the gear 2 to rotate so that the transmission shaft 330 drives the coating roller 320 on the yoke 310 to rotate around the transmission shaft 330. The inclined coating roller 320 can adapt to the coating of the narrow transfer paper, so that the coating roller 320 can meet the coating of the transfer paper with different widths. Figure 6 The dotted line position in the figure is the position of the coating roller 320 after rotation. Compared with the initial position of the solid line, the width of the coating mixture 320 is reduced.
