Therefore, a double-sided spraying slit coater is designed. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a double-sided spraying slit coater to solve the problems raised in the above background technology.

[0006] An adjustment mechanism is provided on one side of the support plate, and the adjustment mechanism includes a mounting groove, an electric push rod, a moving block, a fixed rod and a support roller. A mounting groove is opened in the middle of one side of the support plate, an electric push rod is fixedly installed on one side of the inner wall of the mounting groove, a moving block slidably connected to the mounting groove is fixedly installed on the output shaft of the electric push rod, a fixed rod is fixedly installed on one side of the moving block, and a support roller is fixedly installed on one side of the fixed rod.

[0007] In one example, a winding shaft is fixedly installed at the bottom right side of the front side of the support plate, and the outer ring of the winding shaft is wound with the substrate.

[0008] In one example, a motor is fixedly mounted on one side of the support plate, a sleeve is fixedly mounted on the output shaft of the motor, and the sleeve penetrates and extends outside the support plate.

[0009] In one example, one end of the sleeve is threadedly connected to a receiving shaft, and the receiving shaft is wound around the substrate.

[0010] In one example, a fixed shaft is threadedly connected to one side of the mold, and a crank is fixedly mounted on one end of the fixed shaft.

[0011] In one example, a connecting plate is fixedly mounted on the outer ring of the fixed shaft, and a pressure wheel is rotatably connected to one side of the connecting plate.

[0012] The double-sided spraying slit coating machine proposed by the utility model can bring the following beneficial effects:

[0013] 1. This double-sided spraying slit coater can drive the moving block to move in the installation groove by starting the electric push rod, and drive the support roller to move through the fixed rod, thereby driving the substrate to move and engage with the die lip, so that the distance between the coated substrate and the die lip can be adjusted, which is convenient for adjusting the coating thickness.

[0014] 2.
