[0006] Preferably, four supporting legs are installed at the four corners of the bottom end of the coating table in a rectangular array, and a reinforcing rod is installed between the lower ends of the four supporting legs. By installing the reinforcing rod between the lower ends of the four supporting legs, the supporting strength of the four supporting legs is increased.

[0007] Preferably, a limiting sleeve is sleeved on both ends of each deflection roller, and an adjusting screw is spirally connected to each of the four limiting sleeves. By setting the limiting sleeve, the adhesive tape base material is limited.

[0008] Preferably, the pressing mechanism consists of a U-shaped frame, two lifting electric rods, two smooth rods, a mounting plate, and a pressure roller. Two lifting electric rods are symmetrically installed at the top center of the U-shaped frame beam, and two smooth rods are symmetrically slidably installed at both ends. The extended ends of the two lifting electric rods and the lower ends of the two smooth rods are all mounted on a mounting plate, and a pressure roller is installed at the bottom of the mounting plate. By setting up the pressing mechanism, the flattened adhesive tape substrate is pressed.

[0009] Preferably, the coating box is equipped with a coating device. The coating device is used to coat the tape substrate.

[0010] Preferably, the control box is installed at the bottom of the coating table, close to the inside of the right support leg. The control box is electrically connected to the first lifting electric rod, the motor, and the second lifting electric rod. By setting up the control box, the overall coating operation can be easily controlled.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] During coating, the present invention starts two motors and two lifting electric rods 1 via the control box. The two motors drive two rotating shafts to rotate, which in turn drives two sets of soft elastic teeth on the shafts. The two lifting electric rods 1 drive the rotating soft elastic teeth to contact the surface of the tape substrate. The four sets of rotating soft elastic teeth push the tape substrate from the middle to both sides to make it flat. Then, the control box starts two lifting electric rods 2, which drive the pressure rollers to descend and press the flat tape substrate tightly. This ensures that the tape substrate is always flat during coating, guaranteeing the processing quality of the tape. Attached Figure Description
