[0016] A method for leak-proof detection of fully degradable tableware comprises the following steps:

[0017] S1: During the sealing test of the fully degradable round dinner plate after production, the fully degradable round dinner plate is positioned and placed on the test table through the placement hole. After the placement is completed, the threaded tube is driven to rotate by the driving motor. During the rotation of the threaded tube, the lifting plate is driven to move through the mutual meshing transmission between the threaded tube and the threaded rod;

[0018] S2: During the movement of the lifting plate, the lifting plate and the piston rod on the lifting plate are caused to move downward by the sliding guide action of the third sleeve and the third slide rod;

[0019] S3: During the downward movement of the lifting plate, the connection of the elastic component drives the installation sleeve and the annular seat to move downward. During the downward movement of the installation sleeve, the annular seat is abutted against the upper end of the fully degradable circular dinner plate. The abutment of the fully degradable circular dinner plate facilitates a more stable sealing test of the fully degradable circular dinner plate.

[0020] S4: After the annular seat and the fully degradable circular dinner plate abut against each other, the lifting plate and the piston rod are continuously driven to move downward. During the movement, the piston rod slides inside the mounting sleeve. The sliding of the piston rod pressurizes the interior of the mounting sleeve and the abutting fully degradable circular dinner plate.

[0021] S5: After the pressurization of the inside of the fully degradable circular dinner plate and the installation sleeve is completed, the further downward driving of the lifting plate is stopped. At this time, the inside of the fully degradable circular dinner plate is in a high-pressure state. The pressure change inside the fully degradable circular dinner plate expedited installation sleeve is identified by the pressure sensor on the U-shaped frame. When the pressure is deformed, it is judged that there is a leak inside the fully degradable circular dinner plate. When the pressure remains unchanged, it is judged that the internal sealing of the fully degradable circular dinner plate is good, and the sealing detection operation of the fully degradable circular dinner plate is completed;

[0022] S6: When the sealing test operation of the fully degradable circular dinner plate is performed by sliding the piston rod inside the mounting sleeve, the circular plate is driven to move synchronously by the sliding of the piston rod and the connection transmission between the U-shaped frame and the connecting frame on the identification component. During the movement of the circular plate, the U-shaped scraper is abutted against the inside of the fully degradable circular dinner plate;

[0023] S7: After the U-shaped scraper and the fully degradable circular dinner plate are against each other, the circular plate continues to move toward the U-shaped scraper that is limited by the against position. During the movement, the rotating plate moves toward the U-shaped scraper. During the movement, the transmission rod slides on the circular hole. During the sliding of the transmission rod, the transmission rod and the U-shaped scraper at one end of the transmission rod are driven to rotate through the against transmission effect of the spiral groove and one end of the transmission pin on the mounting frame. Because the U-shaped scraper is against the inside of the fully degradable circular dinner plate, the granular foreign matter adhered to the inner wall of the fully degradable circular dinner plate is scraped and cleaned through the rotation of the U-shaped scraper, so as to avoid the existence of granular foreign matter blocking the dew point on the fully degradable circular dinner plate and ensure the accuracy of the detection.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] This kind of fully degradable tableware leakage-proof detection equipment detects the sealing of the fully degradable round dinner plates after production through the cooperation of the lifting component, the guide component, the detection component and the identification component.

10. A method for leak detection of fully degradable tableware, which is based on the leak detection device of any one of claims 1 to 9, characterized in that: The following steps are involved: S1: During the process of testing the sealing performance of the fully degradable circular dinner plate (2) after production, the fully degradable circular dinner plate (2) is positioned and placed on the testing platform (1) through the placement hole. After the placement is completed, the threaded tube (402) is driven to rotate by the driving motor (404). During the rotation of the threaded tube (402), the lifting plate (3) is driven to move through the mutual meshing transmission between the threaded tube (402) and the threaded rod (403); S2: During the movement of the lifting plate (3), the third sleeve (501) and the third slide rod (502) act as a sliding guide, causing the lifting plate (3) and the piston rod (601) on the lifting plate (3) to move downward after being subjected to force; S3: During the downward movement of the lifting plate (3), the connection function of the elastic component (7) drives the installation sleeve (602) and the annular seat (603) to move downward. During the downward movement of the installation sleeve (602), the annular seat (603) is abutted against the upper end of the fully degradable circular dinner plate (2). The abutment function of the fully degradable circular dinner plate (2) facilitates a more stable sealing test of the fully degradable circular dinner plate (2); S4: After the annular seat (603) and the fully degradable circular dinner plate (2) are in contact with each other, the lifting plate (3) and the piston rod (601) are continuously driven to move downward. During the movement, the piston rod (601) slides inside the mounting sleeve (602). The sliding of the piston rod (601) pressurizes the interior of the mounting sleeve (602) and the contacting fully degradable circular dinner plate (2); S5: After the pressurization of the interior of the fully degradable circular dinner plate (2) and the installation sleeve (602) is completed, the further downward driving of the lifting plate (3) is stopped. At this time, the interior of the fully degradable circular dinner plate (2) is in a high pressure state. The pressure change inside the fully degradable circular dinner plate (2) and the urgent installation sleeve (602) is identified through the pressure sensor (1203) on the U-shaped frame (1201). When the pressure is deformed, it is determined that there is a leak inside the fully degradable circular dinner plate (2). When the pressure remains unchanged, it is determined that the internal sealing of the fully degradable circular dinner plate (2) is good, and the sealing detection operation of the fully degradable circular dinner plate (2) is completed; S6: When the sealing test operation of the fully degradable circular dinner plate (2) is performed by sliding the piston rod (601) inside the mounting sleeve (602), the circular plate (801) is driven to move synchronously by the sliding of the piston rod (601) and the connection transmission between the U-shaped frame (1201) and the connecting frame (1202) on the identification component (12). During the movement of the circular plate (801), the U-shaped scraper (803) is abutted against the inside of the fully degradable circular dinner plate (2); S7: After the U-shaped scraper (803) and the fully degradable circular dinner plate (2) are abutted against each other, the circular plate (801) continues to move toward the U-shaped scraper (803) that is abutted against and limited. During the movement, the rotating disk (802) moves toward the U-shaped scraper (803). During the movement, the transmission rod (1102) slides on the circular hole (1101). During the sliding of the transmission rod (1102), the spiral groove (1103) and the transmission pin (1101) on the mounting frame (1104) are connected. The transmission effect of the U-shaped scraper (803) at one end of the transmission rod (1102) and the U-shaped scraper (803) at one end of the transmission rod (1102) is driven to rotate. Since the U-shaped scraper (803) is against the inside of the fully degradable circular dinner plate (2), the granular foreign matter adhering to the inner wall of the fully degradable circular dinner plate (2) is scraped and cleaned by the rotation of the U-shaped scraper (803), so as to avoid the granular foreign matter from blocking the dew point on the fully degradable circular dinner plate (2), thereby ensuring the accuracy of the detection.
