By rotating the adjusting screw 825, the adjusting screw 825 can drive the sensing plate 826 to rise and fall when rotating. By observing the corresponding positions of the sensing plate 826 and the pressure line 829 on the vertical plate 828, the rotation of the adjusting screw 825 can be stopped, so that the pressure value of the device can be adjusted, so that the device can detect a variety of products. When the sensing plate 826 is raised or lowered, the slide rod 827 can limit the sensing plate 826, so that the sensing plate 826 can be stably raised or lowered, thereby improving the stability of the device.
[0040] In a preferred embodiment, the inner wall of the fixed shell 3 is rotatably connected to a positive screw rod 4, and the outer edge of the positive screw rod 4 is fixedly equipped with a negative screw rod 5.

The negative screw rod 5 and the positive screw rod 4 have a longer stroke, so that the distance between the clamp 2 7 and the clamp 1 6 can be flexibly fixed, so that paper cups of different diameters can be fixed in the center.
[0041] Working principle: when in use, place the paper cup on the fixed shell 3, and then rotate the reverse screw rod 5 and the positive screw rod 4. The reverse screw rod 5 and the positive screw rod 4 rotate and drive the clamping piece 2 7 and the clamping piece 1 6 to move to both sides respectively. The paper cup is clamped by moving the clamping piece 2 7 and the clamping piece 1 6 to both sides. Then, the power output shaft of the servo motor 808 rotates to drive the active disk 807 to rotate. Then, when the active disk 807 rotates again, it will drive the belt 806 to rotate. When the belt 806 rotates, it will drive the internal thread turntable 803 to rotate. When the internal thread turntable 803 rotates, it can drive the lifting screw rod 802 to move downward. Then, the pressing disc 801 contacts the paper cup, and the adjusting screw rod 825 is rotated. When the adjusting screw rod 825 rotates, it drives the induction plate 826 to move downward. By observing the induction plate 826 and the vertical At the position corresponding to the pressure line 829 on the plate 828, when the sensing module 814 moves downward and detects the sensing plate 826, the servo motor 808 stops rotating. When the paper cup is not damaged, the quality of the paper cup meets the standard. When the paper cup is damaged, the quality of the paper cup does not meet the standard. Then, the heating plate 823 is energized to generate heat to heat the water in the water tank 822. Then, water is pumped from the water tank 822 by the water pump 821. The water enters the paper cup through the water supply pipe 817. Water can remain in the paper cup. Then, the right solenoid valve 818 is closed, and then the booster pump 824 is operated to input the gas into the paper cup filled with water through the pressure supply pipe 819. At this time, the inner cavity of the paper cup is pressurized, and then the left solenoid valve 820 is closed. Then, the paper cup is left to stand for 5 minutes to observe whether the bottom of the paper cup leaks.
