[0004] 2. Tilt test: Manually tilt the paper-plastic cup 45 degrees and keep it for two minutes to observe whether the paper-plastic cup leaks;

[0005] 3. Tilt and rotate test: Manually tilt the paper-plastic cup 45 degrees, then hold the side wall of the paper-plastic cup with one hand, and hold the bottom of the paper-plastic cup with the other hand and rotate it.

[0006] 4. Swing test: Hold the paper-plastic cup in your hand and swing it back and forth to observe whether the paper-plastic cup leaks.

[0007] Currently, leakage of paper plastic cups is detected by manual shaking, which is inefficient, time-consuming and labor-intensive. Utility Model Content

[0008] In order to solve the technical problem in the background art that manual shaking is required to detect whether a paper plastic cup is leaking, the purpose of the utility model is to provide a leakage detection device for a paper plastic cup, which can solve the above problem.

[0009] The technical solution for achieving the purpose of the utility model is: a leak detection device for a paper-plastic cup, comprising a mounting frame, a rotating plate, a mounting rod and a driving device, wherein the mounting frame comprises two opposite side plates, the rotating plate is rotatably mounted on the side plates, and the paper-plastic cup is fixed on the rotating plate; the mounting rod is mounted on the rotating plate, and the driving device is connected to the mounting rod and drives the rotating plate to rotate; a rotating mechanism is also provided on the rotating plate, and the rotating mechanism comprises a driving motor and a clamping mechanism, the driving motor is mounted on one side of the rotating plate, the output end of the driving motor passes through the rotating plate and is connected to the clamping mechanism, the paper-plastic cup is mounted on the clamping mechanism, and the driving motor drives the paper-plastic cup to rotate along its own axis.

[0010] In this scheme, the paper plastic cup is fixed on the rotating plate, and the rotating plate is rotatably fixed between the two side plates of the mounting frame. Therefore, after the mounting rod is fixed to the rotating plate, the driving device can drive the rotating plate to rotate after being connected to the mounting rod, and the paper plastic cup can be driven to rotate in the vertical direction with the center line of the rotating plate as the axis. After rotation, it can be seen whether there is a leakage problem after the paper plastic cup is buckled on the cup body. The driving device can be a motor drive or other power device, as long as it can drive the mounting rod to rotate. There are also many ways to fix the rotating plate on the side plate, such as a bearing is installed on the side plate, and the rotating plate and the bearing are installed and rotated in coordination. When there are multiple rotating plates, the rotating plates at both ends are connected to the side plates in rotation, and the multiple rotating plates are connected and fixed by the mounting rod; in order to improve the stability of the rotating plate, the mounting rod can be two, and the fixed structure is relatively stable after the rotating plate is installed on the two mounting rods. The driving device is only connected to one of the mounting rods to drive the rotating plate to rotate. The device has a simple structure, and can realize automatic side leakage of paper plastic cups without consuming manpower, thereby improving the detection efficiency. While the driving device drives the paper-plastic cup to rotate circumferentially along the axis of the mounting rod, the driving motor can also drive the paper-plastic cup to rotate along its own axis, thereby increasing the rotation amplitude during leak detection and improving detection efficiency and accuracy.

[0011] Furthermore, the clamping mechanism includes a chuck structure and a hoop structure, the chuck structure is clamped on the bottom of the paper plastic cup, the hoop structure is clamped on the middle and upper part of the paper plastic cup, and the driving motor is connected to the chuck structure. The chuck structure clamped on the bottom of the paper plastic cup and the hoop structure clamped on the middle and upper part of the paper plastic cup have a good effect of fixing the paper plastic cup. When the paper plastic cup rotates along the circumferential direction of the mounting rod and rotates around its own axis, the paper plastic cup will not tilt or even fall off the leak detection device.

By using the fixing hole on the annular plate and the output end of the drive motor to complete the fixation, the drive motor can drive the paper plastic cup to rotate along its own axis, and then the space formed by the bolt heads of the plurality of limiting bolts can just clamp the bottom of the paper plastic cup. The structure is simple, and the components are commonly used, so there is no need to customize them separately, which reduces enterprise costs.

[0014] Furthermore, the chuck structure also includes mounting bolts, and the fixed plate also has an arc-shaped mounting strip hole arranged along the outer peripheral edge, and the annular plate has corresponding bolt holes, and the mounting bolts pass through the arc-shaped mounting strip hole and the bolt hole in sequence and fix the fixed plate and the annular plate. After the clamping of the bottom of the paper-plastic cup is completed as described above, the fixing plate and the annular plate are fixed by mounting bolts. Since the limit bolts are already in the appropriate position after the annular plate is rotated before, an arc-shaped mounting strip hole is arranged on the fixed plate, and the bolt holes on the edge of the annular plate correspond to the positions of the arc-shaped mounting strip holes, so there is no need to deliberately adjust the relative positions of the fixed plate and the annular plate. There will always be a position in the arc-shaped mounting strip hole that corresponds to the bolt hole, and the mounting bolts can be installed accordingly.

[0015] Furthermore, the clamp structure includes at least two arc clamps and a connecting rod, and the arc clamps have mounting holes at both ends, and the connecting rod is inserted into the mounting holes; the arc clamp also has a locking hole that is laterally connected to the mounting holes, and a locking bolt is installed in the locking hole to lock the connecting rod in the mounting hole. In other words, the position of the connecting rod in the mounting hole is adjustable, and can be adjusted according to the size of the paper-plastic cup. After adjusting to a suitable position, the connecting rod is locked and fixed by screwing the locking bolt into the locking hole.

[0016] Furthermore, the clamping mechanism also includes a limiting rod, a first connecting block, a second connecting block and a fixing clamp, wherein the first connecting block is fixed to the hoop structure, the second connecting block is fixed to the chuck structure, the fixing clamp is installed on the limiting rod, and the first connecting block is fixed to the fixing clamp by a fixing bolt.

[0017] Furthermore, the driving device includes a motor, a disk body and a connecting rod. The disk body is placed vertically, the motor is installed on one side of the disk body and drives the disk body to rotate, a connecting shaft is installed on the other side of the disk body, and both ends of the connecting rod have mounting sleeves mounted on the connecting shaft and the mounting rod respectively. A crank rocker structure is formed between the disk body, the connecting rod and the rotating plate. After the motor drives the disk body to rotate, it drives the connecting rod to move up and down, and then drives the rotating plate to rotate, thereby achieving the purpose of rotating the paper-plastic cup.

[0018] Furthermore, the disk body is provided with a plurality of mounting holes at different distances from the center of the circle, and the connecting shaft is installed in the mounting hole, that is, the amplitude of rotation of the paper-plastic cup along the axis of the mounting rod can be adjusted, and corresponding adjustments can be made according to different leak detection needs.
