[0014] Example 1; as Figure 1 and Figure 3As shown, this utility model proposes a drinking cup life testing device, which is set on a workbench 1, and a frame 2 is set on the workbench 1. A cup clamping mechanism is set on the workbench 1 to clamp the cup. A mounting base 8 is slidably set on the frame 2 along the vertical direction. Specifically, multiple guide rails 10 are set on the frame 2 along the vertical direction, and multiple sliders 9 are set on the mounting base 8. The sliders 9 slide with the guide rails 10. A cup lid clamping mechanism is set on the mounting base 8 to clamp the cup lid. A power mechanism is set on the mounting base 8 to drive the cup lid clamping mechanism to rotate in a cyclic forward and reverse direction. The cup lid clamping mechanism drives the cup lid to tighten and loosen continuously, thereby simulating the tightening and loosening of the cup lid in actual use. The cup clamping mechanism is equipped with an air nozzle 5 that is inserted into the cup body from the bottom. The air nozzle 5 is connected to an external ventilation device, and air can be injected into the cup body to detect leakage. It should be noted that the bottom of a normally used cup body does not have a hole for inserting the air nozzle 5. Only the sampled test cups will have holes machined on their bottoms. The air nozzle 5 is inserted into the hole to seal the hole, and at the same time, the air nozzle 5 can also be used to position the cup body. In an optional embodiment, multiple test fixtures are arranged side by side on the workbench 1 and the frame 2, and multiple drinking cups can be placed and tested at the same time, which can improve the efficiency of drinking cup life test. In this application, three sets of test fixtures are provided.
[0015] Example 2; as Figure 1 and Figure 3 As shown, this utility model proposes a drinking cup life testing device. Compared with Embodiment 1, this embodiment details the structure of the cup clamping mechanism. The cup clamping mechanism includes a positioning base 3 on the workbench 1, a cup positioning seat 4 on the positioning base 3, a cup clamping cylinder 6 on the frame 2, and cup clamping blocks 7 on the two moving ends of the cup clamping cylinder 6. The cup is placed on the cup positioning seat 4, and the two cup clamping blocks 7 clamp the cup. The cup clamping cylinder 6 used here is a finger cylinder, which has two moving parts that move closer or further apart from each other. The cup clamping blocks 7 are connected to the moving parts. An air nozzle 5 is set on the cup positioning seat 4, and the cup positioning seat 4 is provided with an air inlet that communicates with the air nozzle 5, and an external air supply device is connected through the air inlet.
[0016] Example 3; as Figure 2As shown, this utility model proposes a drinking cup life testing device. Compared with Embodiment 1, this embodiment details the lifting structure of the mounting base 8. A base block 11 is provided on the back of the mounting base, and a cylinder 12 is provided on the back of the frame 2. The telescopic rod of the cylinder 12 passes through the base block 11. A disc 13 is provided at the top of the telescopic rod of the cylinder 12, and a buffer pad 14 is provided at the bottom of the disc 13. A nut 16 is provided at the bottom of the telescopic rod of the cylinder 12, and a spring 15 is fitted on the telescopic rod. The bottom of the spring 15 is connected to the nut 16, and the top of the spring 15 abuts against the wall of a blind hole opened at the bottom of the base block 11. The lifting and lowering of the mounting base 8 is driven by the extension and retraction of the cylinder 12. Specifically, the retraction stroke of the cylinder 12: the cylinder 12 retracts... When the disc 13 presses against the upper surface of the base block 11, the buffer pad 14 acts as a buffer. The disc 13 moves downward, pulling the base block 11 downward. The base block 11 presses down on the upper surface of the spring 15 in its blind hole, and the spring 15 is compressed. The cylinder 12 extends its stroke: When the test of the cup lid is completed, the moment the telescopic rod of the cylinder 12 extends upward, the spring 15 quickly rebounds, which helps the extension stroke of the cylinder 12 and plays a quick return role. This can quickly separate the cup lid and the cup body, prepare for the next work, and make it easier for the operator to put in a new cup body.
[0017] Example 4; as Figure 1 and Figure 4 As shown, this utility model proposes a drinking cup life testing device. Compared with Embodiment 1, this embodiment details the structure of the power mechanism and the cup lid clamping mechanism. The power mechanism includes a motor base 19 mounted on the mounting base 8, a motor 17 mounted on the motor base 19, a reducer 18 mounted on the output end of the motor 17, a coupling 20 mounted on the output end of the reducer 18, and a pneumatic slip ring 21 mounted on the bottom end of the coupling 20. The motor 17, reducer 18, coupling 20, and pneumatic slip ring 21 are arranged sequentially from top to bottom.
[0018] The cup lid clamping mechanism includes a connecting plate 22 located at the bottom of the pneumatic slip ring 21, a cup lid clamping cylinder 23 located at the bottom of the connecting plate 22, and cup lid clamping blocks 24 located on the two moving ends of the cup lid clamping cylinder 23. The two cup lid clamping blocks 24 clamp the cup lid from both sides. The cup lid clamping cylinder 23 used here is a finger cylinder, which has two moving parts that move closer or further apart from each other. The cup lid clamping blocks 24 are connected to the moving parts. The air inlet of the pneumatic slip ring 21 is connected to both the external air supply device and the air inlet of the cup lid clamping cylinder 23, and the air outlet of the pneumatic slip ring 21 is connected to both the external air supply device and the air outlet of the cup lid clamping cylinder 23.
[0019] Furthermore, a limit plate 28 is provided on the connecting plate 22, and a limit switch 25 is provided on the frame 2. The limit switch 25 has an upper arm 26 and a lower arm 27. When the limit plate 28 rotates to contact the lower surface of the upper arm 26, the cup lid is in a loose state. When the limit plate 28 rotates to contact the upper surface of the lower arm 27, the cup lid is in a tight state. It should be noted that because of the limit switch 25, the cup lid clamping mechanism needs to first rotate the limit plate 28 to the left or right side, and then rotate it 90° so that the limit plate 28 enters between the upper arm 26 and the lower arm 27 of the limit switch 25.
[0020] Furthermore, in order to achieve working control of motor 17, a control system is set on the worktable. The control system is connected to motor 17 and to limit switch 25 for signal transmission. When upper arm 26 rotates to contact the lower surface of upper arm 26, the control system receives a signal from limit switch 25 and controls motor 17 to rotate in the opposite direction. When limit plate 28 rotates to contact the upper surface of lower arm 27, the control system receives a signal to control motor 17 to rotate in the opposite direction again, thereby realizing the continuous tightening and loosening of cup lid.
[0021] In summary, when using this utility model, first place the cup body on the cup body positioning seat 4, with the air nozzle 5 inserted into the cup body, fixing the bottom of the cup body. The cup body clamping cylinder 6 clamps and fixes the cup body, and the cup lid is screwed onto the cup body. Then, the cylinder 12 retracts, causing the mounting base 8 to move down, and the cup lid clamping block 24 moves down to the position of the cup lid. The cup lid clamping cylinder 23 is activated, clamping the cup lid through the two cup lid clamping blocks 24. Then, the motor 17 rotates, driving the entire cup lid clamping... The cup lid is first loosened by rotating the cup holding mechanism, and then tightened again. This cycle is repeated. In this application, the cup lid clamping mechanism rotates three times to tighten the cup lid, and then rotates three times to loosen the cup lid. The rotation angle is controlled by the limit switch 25 and the limit plate 28. After the tightening and loosening cycle of the cup lid is set a number of times, air is injected into the cup body through the air nozzle 5, and the leakage value is measured once. Then the forward and reverse rotation of the motor 17 continues until the gas leakage is measured. The life of the drinking cup is determined based on the total number of forward and reverse rotations.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
