The rotation of the adjusting screw 17 can drive the moving plate 7, the pressure sensor 11, the support frame 6, the clamping screw 14 and the clamping plate 15 to move upward. While the clamping plate 15 moves, it can pull the hot melt adhesive stick upward, thus facilitating the personnel to detect the viscosity strength of the hot melt adhesive stick. And when the hot melt adhesive stick detaches from the surface of the detection plate 5, under the continuous movement of the moving plate 7, the guide frame 19 can be driven to move. During the movement of the guide frame 19, the inclined surface can contact the surface of the rotating cylinder 24, and the rotating cylinder 24 can be pushed to move to the left through the inclined surface. The movement of the rotating cylinder 24 can drive the moving frame 25 and the cleaning scraper 22 to move. Under the action of the movement of the cleaning scraper 22, the hot melt adhesive adhered to the top of the detection plate 5 can be effectively scraped off, thus achieving the effect of effectively cleaning the residual hot melt adhesive on the top of the detection plate 5. The overall operation is convenient and fast, bringing great convenience to the subsequent hot melt adhesive detection operation of the personnel.
