Detailed Embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Embodiment 1

[0019] Referring to Figures 1-3 , a coating machine includes a bottom plate 1, and a transfer roller 2 is installed on the bottom plate 1. By passing the paper through the transfer roller 2 and winding the paper through a winding device, the paper is transported and coated with paint.

[0020] A coating roller 12 is arranged above the transfer roller 2. The coating roller 12 is adjusted through an adjustment mechanism. Non-stick layers are provided on both the transfer roller 2 and the coating roller 12. The non-stick layer is made of polytetrafluoroethylene material, which is beneficial to reducing the adhesion of paint and facilitating its cleaning.

[0021] When the coating roller 12 is performing coating, it abuts against the paper so as to evenly coat the coating on the paper. A side plate 10 is fixedly connected to the bottom plate 1, a connecting pipe 6 is fixedly connected to the side plate 10, and a plurality of nozzles 7 are communicated with the connecting pipe 6. Sealing columns 9 are abutted inside both ends of the connecting pipe 6, and the two sealing columns 9 are adjusted by a moving mechanism. The connecting pipe 6 is supplied with liquid by a liquid supply mechanism. When the width of the paper changes, the positions of the two sealing columns 9 in the connecting pipe 6 are adjusted by the moving mechanism, so as to block the conduction part between the nozzles 7 and the connecting pipe 6, thereby reducing the number of working nozzles 7, so as to save the coating and avoid waste of the coating when the width of the paper decreases.

[0022] The liquid supply mechanism includes a connecting pipeline 3. One end of the connecting pipeline 3 is communicated with the connecting pipe 6, and the other end is communicated with a liquid supply pump. The liquid supply pump is communicated with a coating storage device, which plays a role in transporting the coating so as to spray it out from the nozzles 7.

[0023] The moving mechanism includes a fixing block 8. The fixing block 8 is fixedly connected to the connecting pipe 6. A threaded sleeve 5 is rotatably connected to the fixing block 8 through a bearing. Threaded rods 4 are threadedly connected to both ends of the threaded sleeve 5. The threading directions of the two threaded rods 4 are opposite. Fixing ears 14 are fixedly connected to both threaded rods 4, and the fixing ears 14 are fixedly connected to the sealing columns 9. By rotating the threaded sleeve 5, the positions of the two threaded rods 4 in the threaded sleeve 5 are adjusted, so as to adjust the positions of the sealing columns 9 in the connecting pipe 6, so as to adjust the number of blocked nozzles 7, so as to perform coating on papers of different widths.

[0024] When in use, by rotating the threaded sleeve 5, the positions of the two threaded rods 4 in the threaded sleeve 5 are adjusted, so as to adjust the positions of the sealing columns 9 in the connecting pipe 6, adjust the number of blocked nozzles 7, open the liquid supply mechanism, and the coating is sprayed from the nozzles 7 onto the paper. When the paper is being transported, the coating roller 12 rotates to evenly apply the coating.

[0025] Embodiment 2

[0026] Referring to Figures 1-3 , as another preferred embodiment of the present invention, on the basis of Embodiment 1, the adjusting mechanism includes a telescopic rod 11. The telescopic rod 11 is installed on the connecting pipe 6. A fixing frame 13 is fixedly connected to the telescopic rod 11. The fixing frame 13 is rotatably connected to the coating roller 12 through a bearing. Due to the different thicknesses of the supports, the telescopic rod 11 is telescoped to adjust the gap between the coating roller 12 and the transmission roller 2, so as to perform coating on papers of different thicknesses.

[0027] Embodiment 3

[0028] Since the sealing column 9 is generally made of an elastic component and is relatively soft, it is likely to cause the sealing column 9 to bend, making it difficult to insert the sealing column 9 into the connecting pipe 6. Refer to Figures 1-3 , as another preferred embodiment of the present invention, on the basis of Embodiment 2, the sealing column 9 includes a fixed column 15. The fixed column 15 is fixedly connected to the fixed ear 14. A rubber sealing sleeve 16 is wrapped around the outer side of the fixed column 15. The outer wall of the rubber sealing sleeve 16 abuts against the inner wall of the connecting pipe 6. The fixed column 15 plays a supporting role, ensuring the straightness of the sealing column 9 and facilitating the insertion of the sealing column 9 into the connecting pipe 6.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
