The scraping process of the present invention is to move from right to left for scraping. The width adjustment device adjusts the coating width between the rear side plate and the front side plate by adjusting the position of the front side plate. The thickness adjustment device adjusts the height between the right side plate and the plate to be coated by adjusting the height of the bottom of the right side plate, thereby adjusting the thickness of the coating. The control system realizes the automatic adjustment of the width of the scraping chamber, which is convenient and quick, and the automatic scraping is uniform, saving time and effort.

[0026] 2. The manual switch on the frame is set to facilitate the staff to manually adjust the start and stop of the Z-axis conveying device, while the operation of the X-axis conveying device and the Y-axis conveying device is automatically controlled by the controller. The staff first inputs the parameters of the plate thickness, coating thickness and coating width through the data input module on the operation panel, transmits the signal to the controller, and the controller analyzes the data, and then controls the Y-axis conveying device to start and descend until the bottom surface of the scraping and coating bin is flush with the top surface of the plate to be coated. Then the staff pours the paint into the scraping and coating bin, presses the switch key, and controls the movement of the X-axis conveying device to realize the coating process of the plate to be coated;

[0027] 3. The setting of the right side plate: when the first cylinder is retracted, the front side plate drives the first moving box to move inwards, and under the action of the clamping plate, the second moving box moves inwards at the same time, thus realizing the width adjustment; when the two sets of second cylinders are retracted, the second moving box and the third moving box are driven to move upwards at the same time, and the distance between the bottom and the plate is increased, thus realizing the thickness adjustment;

[0028] 4. The setting of the mounting frame enables the scraping and coating bin to be detachably fixed on the X-axis conveying device, which is convenient for the staff to disassemble and replace different scraping and coating bins. The staff uses the carrying handle to mount the mounting frame on the connecting rod, and at the same time, the connecting rod bypasses the front side of the "𠃊"-shaped baffle and enters the semicircular groove. The mounting frame not only realizes the movement along the connecting rod, but also plays a limiting role for the mounting frame; the setting of the positioning plate and the slot enables the bottom of the positioning plate to be stuck in the slot when the connecting rod is stuck in the semicircular groove, so that the screw nut can drive the mounting frame to move at the same time when it moves.

[0029] The present invention realizes automatic scraping and coating of the plate, is convenient for adjusting the thickness and width of the coating, saves time and labor, and makes subsequent experimental results of the plate more accurate. BRIEF DESCRIPTION OF THE DRAWINGS
