Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a coating machine for processing lithium iron phosphate positive electrode detection films. Background Art

[0002] A coating machine is a device used to apply coating to the surface of a detection membrane during the processing of a lithium iron phosphate positive electrode detection membrane. When using the coating machine, the first motor is started to move the detection membrane away from the unwinding roller, so that the detection membrane passes through the first coating roller and the second coating roller. At this time, the water pump draws the coating inside the liquid storage tank through the connecting pipe to the inside of the circular tube, and then sets the coating to the surface of the first coating roller through the connecting head at the bottom of the circular tube. When the detection membrane drives the first coating roller and the second coating roller to rotate, the coating can be well applied to the top of the detection membrane, and then the detection membrane passes through the dryer. After being dried by the dryer, the winding roller is driven to rotate by the second motor, so that the detection membrane is well stored on the surface of the winding roller.

[0003] The inventors found in their daily work that the coating machine still has at least the following problems: when using the coating machine, after the lithium iron phosphate positive electrode detection membrane is coated with material between the first coating roller and the second coating roller, the detection membrane must be passed through a dryer to dry the coating, so that the coating adheres well to the detection membrane. However, in actual use, when the detection membrane enters the dryer, the coating that has not yet been dried may occupy the interior of the dryer, and the interior of the dryer may be stained with coating, thereby affecting the working efficiency of the dryer to a certain extent.

[0021] In the utility model, by setting a limit device, when the limit device is used, the threaded rod is manually controlled to rotate, because the direction of the thread on the surface of the threaded rod is opposite from the middle to both sides, which can drive the moving strip of the thread sleeve arranged on the surface of the threaded rod to move relatively, and thus the detection film is well arranged in the middle of the dryer, thereby preventing the paint on the surface of the detection film that has not been dried from being stained by the inside of the dryer, which may cause the surface of the heating wire arranged inside the dryer to be covered with thick paint during long-term use, thus avoiding affecting the efficiency of drying the paint to a certain extent.

The end of the moving strip 802 away from the second motor 10 is fixedly connected with a squeezing plate 807. The connecting part of the squeezing plate 807 and the moving strip 802 is an elastic component. The squeezing plate 807 can be well squeezed on the surface of the detection film through the squeezing of the elastic component, and then the squeezing plate 807 can be well squeezed to smooth the paint.

The rubber strip 810 is pressed against the top of the extrusion plate 807, and the sliding block 809 is manually controlled to slide inside the connecting frame 808, so that the rubber strip 810 pressed against the top of the extrusion plate 807 can scrape off too much paint on one side of the extrusion plate 807 due to extrusion. A spring 811 is fixedly connected to one side of the inner wall of the connecting frame 808, and one end of the spring 811 close to the connecting frame 808 is fixedly connected to one side of the sliding block 809. The sliding block 809 is pulled away from the connecting frame 808 by the spring 811, thereby well restricting the sliding block 809 inside the connecting frame 808.

[0029] Reference Figure 4The adjusting device 9 includes a round rod 902, a connecting groove 901 is provided on one side of the supporting plate 4, the connecting groove 901 is slidably connected to the central axis of the second coating roller 6, the inner wall of the connecting groove 901 is fixedly connected to the round rod 902, the round rod 902 is slidably penetrated and inserted on the top of the second coating roller 6, when the adjusting device 9 is used, the central axis of the second coating roller 6 is manually slid inside the connecting groove 901, so that the second coating roller 6 can be moved away from the first coating roller 5, so that the detection film can be placed between the first coating roller 5 and the second coating roller 6, a limiting groove 903 is provided on one side of the supporting plate 4, the inner wall of the limiting groove 903 is slidably connected to a U-shaped plate 904, one end of the central axis of the second coating roller 6 is fixedly connected to a round plate Block 905, the round block 905 is slidably inserted through one side of the U-shaped plate 904, and the U-shaped plate 904 is manually controlled to slide inside the limiting groove 903, so that the second coating roller 6 can be driven to slide inside the connecting groove 901, and a bolt 906 is threadedly inserted through one side of the U-shaped plate 904, and a rubber plate 907 is provided on one side of the bolt 906. The rubber plate 907 is fixedly connected to one side of the support plate 4. When the second coating roller 6 is moved to a suitable position inside the connecting groove 901, the bolt 906 is manually rotated, so that the bolt 906 is squeezed on one side of the rubber plate 907, so that the rubber is squeezed and deformed, and the central axis of the second coating roller 6 can be well fixed inside the connecting groove 901.

[0030] Working principle: when using the coating machine, start the first motor 2 to move the detection film away from the unwinding roller 3, so that the detection film passes through the first coating roller 5 and the second coating roller 6. At this time, the water pump 13 draws the coating inside the liquid storage tank 12 to the inside of the round tube 15 through the connecting pipe 14, and then sets the coating on the surface of the first coating roller 5 through the connecting head at the bottom of the round tube 15. When the detection film drives the first coating roller 5 and the second coating roller 6 to rotate, the coating can be well applied to the top of the detection film, so that the detection film passes through the dryer 7, and after being dried by the dryer 7, it passes through the second motor 1 0 drives the winding roller 11 to rotate, and then the detection film is well stored on the surface of the winding roller 11. When the limiting device 8 is used, the threaded rod 803 is manually controlled to rotate. Because the thread direction on the surface of the threaded rod 803 is opposite from the middle to both sides, it can drive the moving bar 802 threadedly sleeved on the surface of the threaded rod 803 to move relatively, and then the detection film is well set in the middle of the dryer 7, so as to prevent the paint on the surface of the detection film that has not been dried from being stained with the inside of the dryer 7. At the same time, when the detection film moves inside the dryer 7, it drives the cylinder 806 to rotate on the rotating rod 805. The surface rotates, thereby avoiding to some extent the movement of the detection film, which may cause the surface of the electric heating wire set inside the dryer 7 to be coated with thick paint during long-term use, thereby avoiding to some extent the efficiency of drying the paint, the manual control sliding block 809 slides inside the connecting frame 808, thereby allowing the rubber strip 810 close to the top of the extrusion plate 807 to scrape off too much paint on one side of the extrusion plate 807 due to extrusion, and when the adjustment device 9 is used, the central axis of the manual second paint roller 6 is inside the connecting groove 901 The second coating roller 6 can slide away from the first coating roller 5. When the second coating roller 6 is moved to a suitable position inside the connecting groove 901, the bolt 906 is manually rotated to squeeze the bolt 906 on one side of the rubber plate 907, so that the rubber is squeezed and deformed, and the center axis of the second coating roller 6 can be well fixed inside the connecting groove 901. In this way, it is convenient to place the detection film between the first coating roller 5 and the second coating roller 6. The adjusting device 9 only adjusts the center axis of the second coating roller 6, and will not affect the rotation of the second coating roller 6 along the center axis.
