[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-5 The utility model provides a technical solution: a bottle crack detection device, including a conveyor 1, a turntable 2 is rotatably provided above the conveyor 1, and a plurality of gas injection pipes 3 are provided at the bottom of the turntable 2. The plurality of gas injection pipes 3 are distributed in a circular array with the central axis of the turntable 2 as the center. The inner diameters of the plurality of gas injection pipes 3 increase successively along the circumference direction of the turntable 2. An air outlet is opened on the gas injection pipe 3, and a vertically slidable sealing cylinder 4 is provided on the gas injection pipe 3. The sealing cylinder 4 is used to seal the air outlet. A plurality of pressure gauges 5 are connected to the turntable 2, and the plurality of pressure gauges 5 correspond to the plurality of gas injection pipes 3 respectively.

[0025] It should be noted that an electric telescopic rod may be provided above the conveyor 1 to control the vertical height of the gas injection tube 3 to facilitate the insertion of the gas injection tube 3 into the bottle.

[0026] During specific implementation, the conveyor 1 conveys the bottle to be inspected to the bottom of the turntable 2. The turntable 2 starts to rotate, and moves the gas injection tube 3 corresponding to the bottle to the top of the bottle mouth, and then starts the electric telescopic rod to insert the gas injection tube 3 into the bottle. During this process, the sealing tube 4 slides upward to open the gas outlet, and the gas is blown out from the gas outlet of the gas injection tube 3. The pressure gauge 5 corresponding to each gas injection tube 3 monitors the air pressure in the gas injection tube 3 in real time. When there are no cracks on the surface of the bottle, the gas forms a uniform airflow on the surface of the bottle, and the air pressure value displayed by the pressure gauge 5 is relatively stable. However, if there are cracks in the bottle, the gas will leak from the cracks, causing the air pressure in the gas injection tube 3 to change, and the pressure gauge 5 will detect this change. This setting is convenient for adapting to different types of bottles for testing, and the use of the conveyor 1 for transportation and testing is more efficient.

[0027] See Figure 4 The gas injection pipe 3 is connected to a mounting plate 6, the bottom of the mounting plate 6 is connected to a compression spring 7, and the other end of the compression spring 7 is connected to a sealing cylinder 4.

[0028] In practice, if the sealing cylinder 4 needs to slide upward to open the air outlet, the compression spring 7 will be compressed. The elastic force of the compression spring 7 can provide a certain buffer for the sliding of the sealing cylinder 4, preventing the sudden and rapid sliding of the sealing cylinder 4 from causing impact or damage to the device; on the other hand, when the sealing cylinder 4 needs to be reset to seal the air outlet again, the elastic force of the compression spring 7 will push the sealing cylinder 4 to slide downward, returning it to its original position, and re-sealing the air outlet.

[0029] See Figures 1 to 4 A driving assembly for driving the turntable 2 to rotate is also provided above the conveyor 1, including a driving gear 8 rotatably connected to the top of the conveyor 1, a gear ring 9 is meshed with one side of the driving gear 8, and the gear ring 9 is connected to the turntable 2. A servo motor 10 for driving the driving gear 8 to rotate is provided above the conveyor 1.

[0030] It should be noted that the driving gear 8 is a special-shaped gear.

[0031] During the specific implementation, first start the set servo motor 10 so that the servo motor 10 drives the driving gear 8 to rotate, and then the driving gear 8 can drive the gear ring 9 to rotate, and then the turntable 2 connected to the gear ring 9 can rotate synchronously, thereby adjusting the gas injection tubes 3 of different sizes to contact with different models of bottles.

[0032] refer to Figure 1 The conveyor 1 is connected to a gantry 17 , and the servo motor 10 is connected to the gantry 17 .

[0033] In specific implementation, this arrangement facilitates the installation of various components and facilitates gas detection.

[0034] refer to Figure 1 The gantry 17 is connected to an air pump 11 , the air delivery end of the air pump 11 is connected to an air delivery pipe 12 , and the air outlet end of the air delivery pipe 12 corresponds to the turntable 2 .

[0035] During specific implementation, the provided air pump 11 can generate gas which is transported through the air delivery pipe 12 to the turntable 2 and the air injection pipe 3 for detection.

[0036] refer to Figures 1 to 4 A rotary joint 13 is connected to the turntable 2 , and the outlet end of the gas pipe 12 is rotatably connected to the rotary joint 13 .

[0037] During specific implementation, the provided rotary joint 13 facilitates the rotation of the turntable 2 on the gas pipe 12 .

[0038] refer to Figure 1 At least two guide plates 14 are connected to the conveyor 1 , and a telescopic cylinder 15 is connected to the guide plate 14 , and a clamping plate 16 is connected to the telescopic end of the telescopic cylinder 15 .

[0039] In specific implementation, the guide plate 14 is provided to facilitate the diversion of the conveyed bottles, and the telescopic cylinder 15 and the clamping plate 16 are provided to cooperate with each other to clamp and fix the bottles, so as to facilitate detection.

[0040] refer to Figures 1 to 4 The bottom of the sealing cylinder 4 is connected with a sealing ring.

[0041] It should be noted that the inner wall of the sealing cylinder 4 may be coated with a sealing film.

[0042] In specific implementation, this setting facilitates improving the sealing during gas injection testing.

[0043] Working principle: Conveyor 1 conveys the bottle to be inspected to the bottom of turntable 2. Turntable 2 starts to rotate, and moves the gas injection tube 3 corresponding to the bottle to the top of the bottle mouth, and then starts the electric telescopic rod to insert the gas injection tube 3 into the bottle. During this process, the sealing tube 4 slides upward to open the gas outlet, and the gas is blown out from the gas outlet of the gas injection tube 3. The pressure gauge 5 corresponding to each gas injection tube 3 monitors the air pressure in the gas injection tube 3 in real time. When there are no cracks on the surface of the bottle, the gas forms a uniform airflow on the surface of the bottle, and the air pressure value displayed by the pressure gauge 5 is relatively stable. However, if there are cracks in the bottle, the gas will leak from the cracks, causing the air pressure in the gas injection tube 3 to change, and the pressure gauge 5 will detect this change. This setting is convenient for adapting to different types of bottles for testing, and the use of conveyor 1 for transportation and detection is more efficient;

[0044] On the one hand, the elastic force of the compression spring 7 can provide a certain buffer for the sliding of the sealing cylinder 4, preventing the sudden and rapid sliding of the sealing cylinder 4 from causing impact or damage to the device; on the other hand, when the sealing cylinder 4 needs to be reset to seal the air outlet again, the elastic force of the compression spring 7 will push the sealing cylinder 4 to slide downward, returning it to its initial position and re-sealing the air outlet.
