DETAILED DESCRIPTION
[0015] The technical solutions in the embodiments of the present utility model will be described clearly and completely below.
[0016] like Figure 1 As shown, a coating machine metering roller gap adjustment device includes a frame 1, fixed seats 2 are symmetrically arranged on the frame 1, fixed metering rollers 3 are connected between the fixed seats 2, and mobile metering rollers 4 are arranged on the sides of the fixed metering rollers 3, and movable seats 5 are symmetrically arranged on the frame 1. A linear guide rail 6 is installed at the bottom of the frame 1, a slider 1 is installed on the linear guide rail 6, and the movable seat 5 is installed on the slider 1. A cylinder 7 is installed on the side of the frame 1, and the piston end of the cylinder 7 is connected to the movable seat 5 through a connecting head. The mobile metering roller 4 is connected between the movable seats 5, and the movable seat 5 is moved by the control of the cylinder 7 to make the mobile metering roller 4 close to the fixed metering roller 3.
[0017] Reducers 8 are installed on both sides above the frame 1, and an adjusting screw 9 is arranged on the frame 1. Bearing seats 10 are arranged below and above the frame, and bearings are arranged in the bearing seats 10. The adjusting screw 9 is connected to the bearing seats 10, and the output end of the reducer 8 is connected to the adjusting screw 9 to drive the adjusting screw 9 to rotate. An adjusting block 11 is connected to the adjusting screw 9, and one side of the adjusting block 11 is movably connected to the end face of the fixed seat 2, wherein a linear guide rail 2 12 is installed on the end face of the fixed seat 2, and a slider 2 is installed on the linear guide rail 2 12, and the adjusting block 11 is installed on the slider 2. An adjusting plate 13 is installed on the end face of the movable seat 5, and the surface of the adjusting plate 13 has an inclined surface, and the other side of the adjusting block 11 contacts the inclined surface of the adjusting plate 13.
[0018] In this embodiment, the surface of the adjusting block 11 is processed with a conical surface, which contacts the inclined surface of the adjusting plate 13 and plays a role in fine-tuning the gap between the movable metering roller 4 and the fixed metering roller 3 during the upward and downward movement of the adjusting block 11.
[0019] A limit screw 14 is installed on the upper end of the movable seat 5, and a displacement sensor 15 is installed on the upper end of the fixed seat 2. The displacement sensor 15 faces the limit screw 14. During the adjustment of the gap between the metering rollers, the displacement sensor 15 sets the adjustment distance. When the set distance is reached, the displacement sensor 15 sends a signal to the reducer 8 to stop working.
[0020] The output end of the reducer 8 is connected to the adjusting screw 9 through a torque controller 16. Compared with the diaphragm coupling, the torque controller 16 can better protect the screw. The torque controller adopts a TL200-2 torque limiter. After setting the torque on the torque limiter, the reducer 8 is started. The torque limiter can prevent the displacement sensor 15 from malfunctioning, causing the adjusting screw 9 to be twisted off.
