[0019] The bottle cap leakage detection equipment is adapted to the bottle body and the bottle cap to be tested. The detection is achieved by pumping negative pressure from the bottle body. If the negative pressure value in the bottle body keeps changing after the negative pressure is pumped, it means that there is a leakage at the connection between the bottle body and the bottle cap, and the air tightness of the bottle cap is unqualified. Otherwise, it means that the air tightness of the bottle cap is qualified. The detection equipment can accurately judge whether the bottle cap is qualified and has high efficiency.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 The utility model provides a technical solution: a bottle cap leakage detection device, including a cabinet 1, a driving component 2, a blocking component 3, a bottle body 4, an exhaust pipe 6, a fixing seat 7, an electromagnetic valve 1 8 and an electromagnetic valve 2 9, wherein the number of the driving component 2, the blocking component 3, the bottle body 4, the exhaust pipe 6, the fixing seat 7, the electromagnetic valve 1 8 and the electromagnetic valve 2 9 is eight, and they are in a one-to-one correspondence. The driving component 2 adopts a telescopic cylinder, and the blocking component 3 is essentially a piston, which is a material that can undergo elastic deformation, preferably silicone, rubber, etc. The telescopic end of the driving component 2 is connected to the driving arm 21, and the blocking member 3 is connected to the end of the driving arm 21 through a plug rod 31. An air pressure sensor 32 is embedded at the bottom of the blocking member 3. The air pressure sensor 32 can communicate with the host and the display screen on the cabinet (the host and the display screen are not shown in the figure), that is, the air pressure sensor 32 can display the pressure data through the display screen, the bottle body 4 is installed in the cabinet 1 through the fixing seat 7, the exhaust pipe 6 is connected between the bottle body 4 and the electromagnetic valve 2 9, and the electromagnetic valve 1 8 is connected to the telescopic cylinder;

[0028] When the device is testing, the bottle cap 5 is first tightened on the bottle mouth of the bottle body 4, and then the driving component 2 is shortened, and the driving arm 21 and the plug rod 31 drive the overall structure of the blocking member 3 and the air pressure sensor 32 to move downward until the blocking member 3 is inserted into the inside of the drinking port reserved on the bottle cap 5. At this time, the bottle body 4 and the bottle cap 5 are in a sealed state, and a vacuum device (not shown in the figure) is used, and its vacuum end is connected to the electromagnetic valve 29. When the electromagnetic valve 29 is opened, the air inside the bottle body 4 will be sucked away by the vacuum pipe 6, so that the internal pressure of the bottle body 4 continues to increase. When the pressure reaches the set value, the vacuum is stopped. At this time, the pressure sensor 32 detects whether the pressure value inside the bottle body 4 has changed. If it has changed, it means that there is a problem of loose sealing at the connection between the bottle body 4 and the bottle cap 5, and then this bottle cap 5 is an unqualified product, otherwise, it is a qualified product.

[0029] Also, see Figure 5The fixing seat 7 includes a holder 71 installed inside the cabinet 1, a card plate 72 is installed on the upper part of the holder 71, and adjacent ends of the holder 71 and the card plate 72 are respectively reserved with a reserved groove 1 73 and a reserved groove 2 74. The reserved groove 1 73 and the reserved groove 2 74 are spliced ​​to form a circular structure that matches the outer diameter of the bottle body 4. When fixing the bottle body 4, the bottle body 4 is first placed in the reserved groove 1 73, and then the card plate 72 is placed on the bottle body 4. After placement, the bottle body 4 will be in the reserved groove 2 74 again. In this way, the holder 71 and the card plate 72 are connected and fixed by bolts to complete the fixing of the bottle body 4.
