[0016] See Figure 1-5 This embodiment is a dressing thickness adjustment device for a coating machine, including a coating roller 2 and a pressing roller 3. The coating roller 2 supports the coating 10, and the pressing roller 3 supports the easy-tear adhesive tape 11 and presses the dressing firmly onto the surface of the coating 10 through the easy-tear adhesive tape 11. Each end of the pressing roller 3 is provided with a rotating arm 7, and a bracket 1 is provided on the outer side of the rotating arm 7. One end of the rotating arm 7 is rotatably connected to the bracket 1, and the pressing roller 3 is rotatably connected to the middle of the rotating arm 7. The other end of the rotating arm 7 is a movable end. The bracket 1 is provided with a support plate corresponding to the movable end, and an adjusting screw 8 is mounted on the support plate. The adjusting screw 8 is threadedly connected to the support plate, and the bottom end of the adjusting screw 8 is rotatably connected to the rotating arm 7. The bracket 1 is provided with a dial indicator 6 corresponding to the middle of the rotating arm 7. The probe of the dial indicator 6 abuts against the upper surface of the rotating arm 7 to measure the distance between the pressing roller 3 and the coating roller 2.

[0017] Furthermore, a handwheel 9 is provided at the upper end of the adjusting screw 8.

[0018] Furthermore, the surface of the coating roller 2 is provided with a dressing baffle 4, the two ends of the dressing baffle 4 are fixedly connected to the supports 1 on both sides, and the bottom end of the dressing baffle 4 extends toward the coating roller 2.

[0019] Furthermore, the dressing baffle 4 is equipped with two side baffles 5 on the side facing the pressure roller 3, and the side baffles 5 are used to prevent the dressing from leaking to both sides.

[0020] Furthermore, the dressing baffle 4 is provided with a horizontally arranged adjustment hole 41 corresponding to the side baffle 5, and the side baffle 5 is equipped with a locking screw 42, which passes through the adjustment hole 41 to fix the side baffle 5 and the dressing baffle 4 in a fixed connection.

[0021] By setting the adjustment hole 41, the side baffle 5 can be adjusted to any position within the adjustment hole 41, thereby adjusting the distance between the two side baffles 5 as needed to adapt to the width of the coating 10.

[0022] The working principle of this utility model is as follows: During operation, the coating 10 passes over the coating roller 2, and the easy-tear adhesive 11 passes over the pressure roller 3. The operator pours the prepared dressing into the inner side of the dressing baffle 4. The dressing has a certain fluidity and is fully spread and flattened in the groove-shaped area formed by the dressing baffle 4, the two side baffles 5, and the coating roller 2, thereby making the pressure more uniform. After the dressing is fully spread, the drive mechanism of the coating roller 2 is started, so that the coating roller 2 rotates and drives the dressing through the pressure roller 3. The distance between the pressure roller 3 and the coating roller 2 is the thickness of the dressing. If the thickness of the dressing needs to be adjusted, simply rotate the handwheels 9 at both ends of the pressure roller 3 by the same number of turns. While rotating the handwheels 9, observe the dial indicator 6. When the dial indicator 6 reaches the required value, stop. At this time, the distance between the coating roller 2 and the pressure roller 3 is the adjusted dressing thickness. When the handwheel 9 is rotated, the handwheel 9 drives the adjusting screw 8 to rotate. Since the middle part of the adjusting screw 8 is threadedly connected to the support plate, the screw will move axially when it rotates. The bottom end of the adjusting screw 8 is movably connected to the rotating arm 7, thereby driving the movable end of the rotating arm 7 to rotate around the other end as the axis. When the rotating arm 7 rotates, it will drive the pressure roller 3 to move accordingly, thereby changing the distance between it and the coating roller 2.
