Description

Technical Field

[0001] The utility model belongs to the technical field of coating machines, in particular to a coating machine with a drying mechanism. Background Art

[0002] Coating machines are mainly used for surface coating production of films, paper, etc. This machine coats the rolled substrate with a layer of glue, paint or ink with specific functions. Roller coating uses a coating roller to apply coating to the coating surface. This type of coating machine is mainly used for in-machine coating.

[0003] At present, the existing coating machines are not convenient for drying the coated substrates. After coating, they need to be placed in the drying device again for drying. The operation steps are cumbersome, which reduces the efficiency of substrate coating processing. At the same time, some coating machines with drying functions have fixed air outlets for drying fans during use, which cannot be adapted to the drying of substrates of different widths. There are easily positions that cannot be blown by the wind, and the distance between the substrate and the drying component cannot be flexibly adjusted, which affects the drying effect of the substrate.

[0004] In response to the above problems, we propose a coating machine with a drying mechanism. Utility Model Content

[0033] Example:

[0035] Then, the servo motor 26, the fan 16, and the heating tube 17 are started, and the servo motor 26 drives the winding roller 21 to rotate. Under the joint action of the first transmission assembly 19 and the second transmission assembly 22, the support shaft 12 and the unwinding roller 3 are driven to rotate synchronously. The substrate is wound by the winding roller 21, and when the substrate passes through the coating roller 5, the coating roller 5 coats the surface of the substrate with the coating.

[0036] The coated substrate enters the drying box 2 through the feed port. At this time, during the rotation of the support shaft 12, the reciprocating screw 13 is driven to rotate synchronously. Under the threaded cooperation between the movable block 14 and the reciprocating screw 13, combined with the sliding cooperation between the guide block 25 and the guide rod 24, the movable block 14 is adjusted to reciprocate stably along the direction of the reciprocating screw 13. Under the action of the frame 15, the fan 16 and the heating tube 17 are driven to reciprocate synchronously. Through the mutual cooperation of the fan 16 and the heating tube 17, hot air is blown to the surface of the coated substrate to dry the substrate.

[0037] The staggered arrangement of the movable blocks 14 enables the staggered movement of the frames 15, which in turn drives the staggered movement of the fans 16, effectively expanding the blowing range of the fans 16, making it easier to blow hot air to different parts of the substrate, adapting to the drying process of substrates of different widths, and effectively improving the drying effect of the substrate;

[0038] During the rotation of the support shaft 12, the fixed sleeve drives the rotation of the fan blade 18, and cooperates with the screen 11 to blow external air into the drying box 2, ensuring the use effect of the fan 16 and facilitating the drying process of the substrate;

[0039] When it is necessary to adjust the distance between the substrate and the drying mechanism, the knob is turned to drive the screw 8 to rotate. Through the threaded cooperation between the screw 8 and the lifting block 9, combined with the active cooperation between the limit block and the limit groove, the lifting block 9 is adjusted to move upward stably, driving the lifting plate 10 to move upward, and then driving the two adjusting rollers 6 to move upward synchronously. The substrate is lifted upward by the adjusting rollers 6 on both sides and close to the frame 15, thereby achieving the purpose of adjusting the distance between the substrate and the fan 16 and ensuring the drying effect of the substrate;

[0040] In the process of lifting the substrate upwards by the adjusting rollers 6 on both sides, the purpose of adjusting the stretching degree of the substrate is achieved, which facilitates the heating, drying and winding of the substrate.
