DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0023] Please refer to Figures 1-8 The utility model provides a kind of die structure of lithium battery material coating machine, comprising: die body 1, feed pipe 2 connected to the top of die body 1 and coating roller 3 rotationally installed in the inner wall of die body 1, further comprising: threaded rod 4 rotationally installed on the outer wall of one side of coating roller 3, threaded rod 4 is screwed with moving assembly 5, and moving assembly 5 end rotationally connects with multiple equidistantly distributed support assemblies 6, and the outer wall of one side of coating roller 3 is provided with multiple equidistantly distributed sliding grooves 7, and the inner wall of sliding groove 7 is slidably connected with guide assembly 8, one end of guide assembly 8 is connected with corresponding support assembly 6, and the outer wall of coating roller 3 is provided with multiple equidistantly distributed fixed ports 9, both inner walls of fixed port 9 are hinged with movable plate 10, and the outer wall of coating roller 3 is provided with elastic rubber sleeve 11, and the sticking glue connection between the sticking glue connection between the outer wall sticking portion of elastic rubber sleeve 11 and movable plate 10, and one end of coating roller 3 is provided with gear 12, and the outer wall of one side of die body 1 is provided with limiting assembly 13.
[0024] It needs to be explained here that: die body 1 can be installed on corresponding coating machine, and feed pipe 2 is connected with coating machine feed pipe, the limitation of gear 12 is cancelled by limiting assembly 13, coating material enters die body 1 by feed pipe 2, and falls on the top of coating roller 3, the part of elastic rubber sleeve 11 on fixed port 9 is pulled downward by two movable plates 10, to form concave structure, to facilitate the transfer of coating material;
[0025] The cloth material is coated on the material surface by rolling the coating roller 3 on the material surface by the coating machine. When the coating thickness needs to be adjusted, the coating work can be temporarily stopped, the gear 12 can be limited by the limiting assembly 13, and then the coating roller 3 is limited, so that the coating roller 3 cannot rotate. At this time, the threaded rod 4 can be rotated to drive the moving assembly 5 to move. The moving assembly 5 can drive the supporting assembly 6 to move by moving. By adjusting the supporting assembly 6 to move closer to or away from the fixed port 9, the downward inclination angle of the two movable plates 10 in the fixed port 9 can be adjusted, and then the depth of the concave structure is adjusted. When the supporting assembly 6 moves closer to the fixed port 9, the downward inclination angle of the two movable plates 10 becomes smaller, the concave structure becomes shallower, and the coating thickness becomes thinner. Conversely, the concave structure becomes deeper, and the coating thickness becomes thicker. It is convenient to adjust the coating thickness without disassembling, replacing and reinstalling the coating roller 3, which is more convenient.
[0026] In a preferred embodiment, the moving assembly 5 comprises an inner threaded block 501 and a plurality of moving rods 502 rotatably installed on the outer wall of the inner threaded block 501; the supporting assembly 6 comprises a mounting frame 601, a rotating shaft 602 rotatably installed on the inner wall of the mounting frame 601, and a supporting rod 603 rotatably connected to the outer wall of the rotating shaft 602; one end of each of the two supporting rods 603 is rotatably connected to the two movable plates 10 in the same fixed port 9.

The mounting frame 601 moves through the two supporting rods 603 to move the two movable plates 10 in the fixed port 9, so that the two movable plates 10 move together at one end to make the concave structure shallower. Conversely, rotating the threaded rod 4 in the opposite direction can make the concave structure deeper.
[0028] In a preferred embodiment, the guiding assembly 8 comprises a sliding block 801 and a connecting plate 802 installed on one side of the outer wall of the sliding block 801.
[0029] It should be noted that the connecting plate 802 is connected to the mounting frame 601, and the mounting frame 601 can move stably by driving the sliding block 801 to move in the inner wall of the sliding groove 7 when the mounting frame 601 moves.

[0031] It should be noted that the electric push rod 1301 can drive the limiting block 1302 to move up and down, so that the limiting block 1302 can be pulled out or inserted between the meshing teeth of the gear 12 to cancel the limitation or limit the gear 12.

[0033] The coating roller 3 is driven by the coating machine to roll on the material surface to coat the material on the material surface, when the coating thickness needs to be adjusted, the coating work can be paused first, the limiting block 1302 is driven to descend by the electric push rod 1301 and is inserted into the meshing teeth between the gear 12, the gear 12 is limited, and then the coating roller 3 is limited, so that the coating roller 3 cannot rotate;
[0034] When the coating thickness needs to be thinned, the threaded rod 4 can be rotated, the inner threaded block 501 moves to the direction of the sliding groove 7, and then the moving rod 502 drives the mounting frame 601 to move, so that the mounting frame 601 approaches the fixed port 9, the mounting frame 601 moves and drives the two movable plates 10 in the fixed port 9 to move through the two supporting rods 603, so that the two movable plates 10 move together at one end, the concave structure becomes shallow, and the concave structure becomes deep by rotating the threaded rod 4 in the opposite direction, the concave structure becomes shallow, the coating thickness becomes thin, and vice versa, the concave structure becomes deep, the coating thickness becomes thick, which is convenient for adjusting the coating thickness, without disassembling, replacing and reassembling the coating roller 3, which is more convenient.
