Description

Technical Field

[0001] This invention relates to the field of glass bottle pressure testing technology, specifically to a glass bottle body pressure testing device and its usage method. Background Technology

[0002] Pressure testing of glass bottles is a key technical step in glass container manufacturing and quality control. It is primarily used to assess a bottle's ability to withstand internal or external pressure during actual use, such as filling, transportation, and storage, ensuring sufficient structural strength and sealing reliability. Currently, the industry commonly uses hydrostatic or pneumatic testing methods for pressure performance testing. Pneumatic testing is widely used due to its high efficiency, non-destructive nature, and ease of integration into high-speed production lines. This method involves filling the bottle with compressed air and using a high-precision pressure sensor to monitor pressure decay in real time, thereby determining whether the bottle contains microcracks, bubbles, or structural defects.

[0003] However, in practical applications, environmental temperature and humidity conditions have a significant impact on barometric pressure test results, especially in southern climate regions where high temperatures and humidity persist year-round, with frequent rainy weather and relative humidity often exceeding 80%. Under such conditions, water vapor easily condenses on the surface of the glass bottle, and the sealing area at the bottle neck may experience changes in the friction coefficient of the sealing ring or micro-leakage due to moisture. Simultaneously, high temperatures alter the thermodynamic state of the gas inside the bottle, causing a drift between the initial pressure and the steady-state pressure, thus interfering with the accuracy of the pressure decay curve.

[0004] The combined effect of the above factors can easily lead to misjudgments by the detection system regarding the quality of glass bottles—either misjudging intact bottles as leaks (false positives) or failing to detect bottles with minor defects (false negatives), seriously affecting the reliability and consistency of product quality control.

[0005] To address the shortcomings of existing technologies, this invention provides a glass bottle pressure detection device and its usage method to solve the aforementioned problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a glass bottle pressure detection device and its usage method. It solves the problem in southern climates where high temperature and humidity prevail year-round, frequent rainy weather, and relative humidity often exceeding 80%. In such environments, water vapor easily condenses on the surface of glass bottles, and the sealing area at the bottle mouth may experience changes in the friction coefficient of the sealing ring or micro-leakage due to moisture. Simultaneously, high temperatures alter the thermodynamic state of the gas inside the bottle, causing a drift between the initial pressure and the steady-state pressure, thus interfering with the accuracy of the pressure decay curve. This can easily lead to misjudgments by the detection system regarding the quality of the glass bottle—either misjudging an intact bottle as a leak or missing a bottle with minor defects, seriously affecting the reliability and consistency of product quality control.

[0011] Preferably, the gas injection assembly includes: An air tube is fixedly connected to the connecting plate. One end of the air tube is connected to a compressed air tank, which is fixedly installed on the base. A pressure sensor is fixedly connected inside the air tube. A flexible hose is connected to the air tube; The air injection head is connected to the telescopic hose; A sealing plate is fixedly connected to the gas injection head, so that the sealing plate seals the mouth of the glass bottle; A sliding cylinder is fixedly connected to the sealing plate, and a sliding rod is slidably connected inside the sliding cylinder. The top of the sliding rod is fixedly connected to the connecting plate. A return spring is fitted onto the surface of the slide rod. One end of the return spring is fixedly connected to the connecting plate, and the other end is fixedly connected to the slide cylinder.

[0012] Preferably, the drive groove includes a first vertical groove, an inclined groove, and a second vertical groove, all of which are formed on the surface of the slide plate.

[0013] Preferably, a transverse slide rail is fixedly connected to the front of the vertical slide rail, and the pushing component slides laterally along the transverse slide rail.

[0014] Preferably, the actuating component includes: A slide bar is disposed in the drive groove, allowing the slide bar to move along the drive groove, and the slide bar is slidably connected to the transverse slide rail; The slide block is fixedly connected to the slide rod, allowing the slide block to slide laterally along the transverse slide rail; The gear teeth are hinged to the slide block; The first spring is located between the slide and the gear teeth.

[0015] Preferably, the feeding assembly includes: A gear disk meshes with the gear teeth, and the gear disk has several threaded through holes, with the humidity sensor fixedly installed at the center of the gear disk; A threaded limiting cylinder is threadedly connected to the threaded through hole, and the threaded limiting cylinder is used to hold the glass bottle in place; A rotating rod is rotatably connected to a gear disk, and the bottom of the rotating rod is fixedly connected to the base; A tray, located at the bottom of the gear disk, supports the glass bottle; A support rod is fixedly connected to the tray and also fixedly connected to the base; The feed cylinder is fixedly connected to the pallet and positioned on the rotation trajectory of the threaded through hole; A limiting component is disposed within the tooth groove of the gear disk, and the limiting component is used to limit the rotation direction of the gear disk.

[0016] Preferably, the limiting component includes:

[0017] A limiting post is fixedly connected to the base, and a sliding groove is provided on the top of the limiting post;

[0018] A limiting spring is fixedly connected to the bottom of the slide groove;

[0019] The limiting rod is fixedly connected to the limiting spring.

[0020] Preferably, the cross-section of the limiting rod is wedge-shaped.

[0021] Preferably, a method of using a glass bottle pressure detection device includes the following steps: Step 1: Place the glass bottle inside the threaded limiting cylinder. The controller starts the electric telescopic rod, which pulls the connecting plate and moves the slide downward. The slide rod first moves upward along the second vertical groove, and then the electric telescopic rod continues to pull the slide downward, moving the slide rod along the inclined groove. The slide rod moves the slide block along the transverse slide rail, and at the same time, the slide block drives the gear teeth to rotate the gear disk. The rotation of the gear disk moves the glass bottle accordingly. Step 2: When the gear disk drives the glass bottle to rotate to the directly below of the air injection head, the gear teeth disengage from the gear teeth of the gear disk, the slide rod slides from the inclined groove into the first vertical groove, the temperature sensor is aligned with the glass bottle, so that the temperature sensor transmits the detected temperature of the glass bottle to the controller in real time. At the same time, the humidity sensor on the gear disk transmits the humidity in the device to the controller. Then, the controller calculates the dynamically allowed maximum pressure drop value according to the temperature value and the humidity value through the temperature-humidity compensation formula; Step 3: When the gear disk drives the glass bottle to rotate to the directly below of the air injection head, the slide rod slides from the inclined groove into the first vertical groove, the slide plate continues to move downward to带动 the connecting plate to move along, so that the connecting plate带动 the air injection head to insert into the glass bottle, and also带动 the sealing plate to press on the bottle mouth. The connecting plate continues to move downward to compress the telescopic hose, and at the same time push the slide rod to slide into the sliding cylinder, and compress the return spring. The reverse action of the return spring pushes the sliding cylinder to带动 the sealing plate to tightly press on the bottle mouth; Step 4: The compressed air tank transports the compressed gas to the telescopic hose through the air pipe. The compressed gas enters the air injection head along the telescopic hose, and then the compressed gas is discharged from the air injection head into the glass bottle. At the same time, the pressure sensor on the air pipe transmits the pressure value to the controller in real time. When the pressure value reaches the threshold for detecting the glass bottle, maintain the injection rate and time of the compressed gas, and gradually reduce the pressure value to calculate the actual pressure drop; Step 5: When the actual pressure drop ≤ the dynamically allowed maximum pressure drop value, it is judged as qualified, otherwise it is judged as unqualified.

[0022] Technical effects and advantages of the present invention:

[0023] For the glass bottle body pressure detection device and its usage method, during the detection of the glass bottle body pressure, first select a matching threaded limit cylinder according to the specifications of the待测 glass bottle, and旋入 it into the preset threaded groove on the gear disk by rotation to实现牢固安装, so as to ensure that the device can limit glass bottles with different diameters and heights.

[0024] For the glass bottle body pressure detection device and its usage method, the electric telescopic rod continues to drive the connecting plate to move downward,带动 the air injection head to vertically insert into the glass bottle mouth, and the sealing plate fixed on the outer periphery of the air injection head随之压紧 the bottle mouth end face; the connecting plate is further pressed down,压缩 the telescopic hose, and推动 the slide rod to slide into the sliding cylinder, and at the same time压缩 the return spring. The reverse elastic force generated by the return spring is传递至 the sealing plate through the sliding cylinder,使其紧密贴合 the bottle mouth to form a reliable airtight seal

[0025] The glass bottle pressure detection device and its usage method involve a temperature sensor positioned directly over the glass bottle to collect its surface temperature in real time and transmit it to a controller. A humidity sensor simultaneously monitors the ambient humidity and transmits the data to the controller. Based on the obtained temperature and humidity values, when the internal pressure reaches a preset detection threshold, the system maintains a constant injection rate and pressure holding time, then gradually releases pressure and records the minimum pressure value during the pressure holding phase. The actual pressure drop is determined by the difference between the target pressure and this minimum pressure. If the actual pressure drop is less than or equal to the dynamic maximum allowable pressure drop value, the glass bottle is deemed to be airtight; otherwise, it is deemed unqualified.

[0026] The glass bottle pressure detection device and its usage method are as follows: The controller starts the electric telescopic rod, which drives the sliding plate downward through the connecting plate, so that the sliding rod enters the inclined groove and moves laterally under the guidance of the inclined groove. This pushes the sliding block to drive the gear tooth to rotate the gear disk. When the glass bottle rotates to directly below the air injection head, the gear tooth disengages from the gear disk, and the sliding rod also slides from the inclined groove into the first vertical groove. The electric telescopic rod continues to drive the connecting plate downward, driving the air injection head to be vertically inserted into the mouth of the glass bottle. The sealing plate fixed on the outer periphery of the air injection head then presses against the end face of the bottle mouth. The compressed air tank delivers compressed gas to the telescopic hose through the air pipe, and then injects it into the glass bottle through the air injection head to detect the glass bottle. The gear disk transfers the glass bottle that has completed the detection to directly above the conveying cylinder. Under the action of gravity, the glass bottle slides from the threaded limiting cylinder into the conveying cylinder and finally slides out to the next station, completing the entire detection and sorting cycle, thereby realizing the conveying and discharge of glass.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] This embodiment discloses a glass bottle body pressure detection device and its usage method, according to the appendix. Figure 1 To be continued Figure 9 As shown, it includes a base 1, a vertical slide rail 2 fixedly installed on the top of the base 1, and a slide plate 3 slidably installed inside the vertical slide rail 2, so that the slide plate 3 slides up and down along the vertical slide rail 2. A connecting plate 4 is fixedly installed on the top of the slide plate 3, and the telescopic end of an electric telescopic rod 5 is fixedly installed on the bottom side of one side of the connecting plate 4. The electric telescopic rod 5 is fixedly installed on the side of the vertical slide rail 2. An air injection assembly 6 is installed on the other side of the connecting plate 4. The air injection assembly 6 consists of an air pipe 61, a telescopic hose 62, an air injection head 63, a sealing plate 64, a slide cylinder 65, a slide rod, and a return spring 66. One end of the air pipe 61 is connected to the compressed air tank 7, and the other end passes through the connecting plate 4 and is connected to the telescopic hose 62 to form a gas delivery passage. A pressure sensor is fixedly installed on the air pipe 61 to monitor the gas pressure entering the system in real time. On the side of the air pipe 61 away from the pressure sensor and close to the compressed air tank 7, a flow control valve is also installed to precisely adjust the gas flow rate and ensure that the pressurization process is stable and controllable. An annular sealing plate 64 is fixedly installed on the outer surface of the telescopic hose 62. Its function is to press and seal it to the end face of the glass bottle mouth during gas injection to prevent gas leakage. After the telescopic hose 62 passes through the central hole of the sealing plate 64, its end is fixedly connected to the gas injection head 63. The gas injection head 63 is used to insert into the bottle mouth and inject compressed air into the bottle. Several sliding cylinders 65 are evenly fixedly installed on the top of the sealing plate 64; a sliding rod is slidably installed inside each sliding cylinder 65, and the upper end of the sliding rod is fixedly connected to the connecting plate 4. A return spring 66 is sleeved on the outer periphery of each sliding rod, one end of which is fixed to the bottom or inner wall of the sliding cylinder 65, and the other end is fixed to the bottom surface of the connecting plate 4; When the electric telescopic rod drives the connecting plate 4 to move downward, the slide rod pushes the slide cylinder 65 and the sealing plate 64 fixed thereto to move downward synchronously, so that the gas injection head 63 is inserted into the bottle mouth, and at the same time the sealing plate 64 presses the bottle mouth to achieve a seal; during this process, the return spring 66 is compressed and stores elastic potential energy. After the test is completed, the connecting plate 4 moves upward, the return spring 66 releases energy, and pushes the sealing plate 64 to quickly return to its original position and detach from the bottle mouth, in preparation for the next test; A drive groove 8 is opened on the side of the slide plate 3. The drive groove 8 is composed of a first vertical groove 81, an inclined groove 82, and a second vertical groove 83. The first vertical groove 81, the inclined groove 82, and the second vertical groove 83 are connected in sequence. A push component 9 is installed in the first vertical groove 81, and the push component 9 slides laterally along the transverse slide rail 21 fixedly installed on the vertical slide rail 2. The pushing component 9 consists of a slide rod 91, a slide seat 92, a gear tooth 93, and a first spring 94. One end of the slide rod 91 is slidably installed in the second vertical groove 83 and slides up and down along the side wall of the transverse slide rail 21. One end of the slide rod 91, which passes through the transverse slide rail 21, is fixedly connected to the slide seat 92, thereby driving the slide seat 92 to reciprocate horizontally along the transverse slide rail 21.

[0040] Inside the slide 92, the gear tooth 93 is hinged via a pin, allowing it to rotate around the hinge point. One end of the first spring 94 is fixedly connected to the outer end of the gear tooth 93, while the other end of the first spring 94 is fixed to the inner wall of the slide 92. The first spring 94 always applies an outward elastic force to the gear tooth 93, keeping it extended in the absence of external interference, thus ensuring reliable engagement or disengagement from the gear slots of the gear disk 111.

[0041] This structure drives the slide block 92 to move laterally by changing the movement trajectory of the slide rod 91 in different guide grooves (such as the second vertical groove 83, the inclined groove 82, and the first vertical groove 81). Combined with the elastic reset effect of the first spring 94, it realizes the automatic engagement and disengagement between the gear teeth 93 and the gear disk 11, thereby completing the precise positioning, rotational conveying, and reset actions of the glass bottle, providing a reliable mechanical transmission foundation for the fully automated inspection process. The gear 93 is connected to the conveying assembly 11, which consists of a gear disk 111, a threaded limiting cylinder 112, a support plate 113, a support rod 114, a rotating rod 115, and a conveying cylinder 116. The gear disk 111 and the gear 93 form a meshing transmission relationship to achieve precise rotational positioning of the glass bottle. Several equally spaced threaded through holes are opened on the gear disk 111 along the circumferential direction. A threaded limiting cylinder 112 is threadedly connected in each threaded through hole. The threaded limiting cylinder 112 is used to fit and clamp glass bottles of different specifications. By matching its inner diameter with the bottle body, it effectively limits the radial and circumferential displacement of the glass bottle and ensures that it remains stable during the inspection process. At the center of the bottom of the gear disk 111, a rotating rod 115 is rotatably mounted via a bearing. The lower end of the rotating rod 115 is fixed to the base 1, allowing the gear disk 111 to rotate freely around the rotating rod 115. A support plate 113 is fixedly mounted on the outer circumferential surface of the rotating rod 115. The support plate 113 is located directly below the gear disk 111 and is used to support the bottom of the glass bottle to prevent it from sinking due to its own weight during rotation or testing. A support rod 114 is vertically fixed to the bottom of the tray 113, and the other end of the support rod 114 is also firmly connected to the base 1. In addition, a conveying cylinder 116 is fixedly installed on the pallet 113. Its position is precisely arranged to ensure that its inlet is directly opposite the rotating docking station of the threaded limiting cylinder 112 after the inspection is completed. When the gear disk 111 drives the inspected glass bottle to rotate to the specified angle, the threaded limiting cylinder 112 is exactly above the conveying cylinder 116. The glass bottle slides smoothly into the conveying cylinder 116 under the action of gravity and is discharged along its channel to the next process. A limit assembly 12 is provided on the tooth groove of the gear disk 111. The limit assembly 12 consists of a limit post 121, a limit spring 122, and a limit rod 123. The limit post 121 is fixedly installed on the top of the base 1, and an upper sliding groove is opened inside the limit post 121. The upper limit spring 122 is fixedly installed in the sliding groove, and the upper limit rod 123 is slidably installed on the top of the limit spring 122. The limit rod 123 slides in the sliding groove. The cross section of the limit rod 123 is wedge-shaped, and the inclined surface faces the direction of rotation of the gear disk 111. Then, the controller 14 is fixedly installed on the front of the vertical slide rail 2, and the temperature sensor 10 is fixedly installed on the top of the horizontal slide rail 21. The temperature sensor 10 is used to detect the temperature of the glass bottle. The humidity sensor 13 is also fixedly installed at the top center of the gear disk 111. The controller 14 is electrically connected to the humidity sensor 13, the temperature sensor 10, the electric telescopic rod 5, and the pressure sensor respectively. The controller (14) is equipped with a temperature and humidity compensation formula, which is as follows:

[0042] Set reference conditions

[0043] Reference temperature =23℃; Reference humidity =50%; Basic allowable pressure drop =0.010MPa; Calculate the temperature compensation factor

[0044] If T≥23℃ (high temperature environment): Use the quadratic relationship to relax the threshold: ;

[0045] T represents the temperature (°C) of the glass bottle detected by the temperature sensor.

[0046] This design reflects the increased pressure drop caused by normal phenomena such as gas thermal expansion and softening of the sealing ring at high temperatures, which is within an acceptable range;

[0047] When T < 23℃ (low temperature environment):

[0048] Without any relaxation, directly set =10.

[0049] To prevent excessive relaxation, restrictions ;

[0050] Calculate the temperature compensation factor

[0051] When the ambient humidity is higher than 50%, the sealing surface is susceptible to moisture, increasing the risk of micro-leakage. Therefore, linear compensation is only performed under high humidity conditions.

[0052] Same restrictions To avoid overly lenient judgments when humidity is too high;

[0053] Calculate the maximum allowable voltage drop dynamically

[0054] Multiply the two compensation factors together and apply them to the base pressure drop:

[0055] And the results are subject to engineering limits: final It is constrained between 0.010MPa and 0.020MPa to ensure that it is neither too tight nor too loose.

[0056] The working principle of the glass bottle pressure detection device is as follows:

[0057] During the pressure test of the glass bottle body, firstly, a matching threaded limiting cylinder 112 is selected according to the specifications of the glass bottle to be tested, and then it is screwed into the preset threaded groove on the gear plate 111 by rotation to achieve a firm installation, thereby ensuring that the device can limit glass bottles of different diameters and heights.

[0058] Subsequently, the glass bottle to be inspected is placed into the threaded limiting cylinder 112. The controller 14 starts the electric telescopic rod 5, which drives the connecting plate 4 and the slide plate 3 to move downward synchronously. During this process, the slide rod 91 first slides upward along the second vertical groove 83. As the slide plate 3 continues to descend, the slide rod 91 enters the inclined groove 82 and moves laterally under the guidance of the inclined groove 82, pushing the slide block 92 to slide to the right along the transverse slide rail 21. The slide block 92 drives the gear teeth 93 to mesh with the external teeth of the gear disk 111, driving the gear disk 111 to rotate, thereby driving the glass bottle to rotate synchronously.

[0059] When the glass bottle rotates to directly below the gas injection head 63, the gear teeth 93 disengage from the gear disk 111, and the slide bar 91 slides from the inclined groove 82 into the first vertical groove 81. At this time, the temperature sensor 10 integrated on the transverse slide rail 21 faces the glass bottle body, collects its surface temperature in real time and transmits it to the controller 14. At the same time, the humidity sensor 13 set on the gear disk 111 synchronously monitors the ambient humidity and transmits the data to the controller 14. The controller 14 dynamically calculates the maximum allowable pressure drop threshold under the current environment based on the obtained temperature and humidity values ​​through a preset temperature and humidity compensation formula, which is used for the adaptive adjustment of the subsequent judgment criteria.

[0060] Next, the electric telescopic rod 5 continues to drive the connecting plate 4 downward, causing the gas injection head 63 to be inserted vertically into the mouth of the glass bottle. The sealing plate 64 fixed on the outer periphery of the gas injection head 63 then presses against the end face of the bottle mouth. The connecting plate 4 presses down further, compressing the telescopic hose 62 and pushing the slide rod into the slide cylinder 65. At the same time, the return spring 66 is compressed. The reverse elastic force generated by the return spring 66 is transmitted to the sealing plate 64 through the slide cylinder 65, so that it fits tightly against the bottle mouth, forming a reliable airtight seal.

[0061] At this time, the compressed gas tank 7 delivers compressed gas to the telescopic hose 62 through the air pipe 61, and then injects it into the glass bottle through the air injection head 63. The pressure sensor on the air pipe 61 monitors the system pressure in real time and feeds it back to the controller 14. When the pressure inside the bottle reaches the preset detection threshold, the system maintains a constant air injection rate and pressure holding time, and then gradually depressurizes and records the minimum pressure value during the pressure holding stage. The actual pressure drop is determined by the difference between the target pressure and the minimum pressure.

[0062] If the actual pressure drop is less than or equal to the maximum allowable dynamic pressure drop, the glass bottle is deemed to be airtight; otherwise, it is deemed to be unqualified.

[0063] After the test is completed, the electric telescopic rod 5 reverses its movement, pushing the connecting plate 4 and the slide plate 3 upward to reset. The slide rod 91 rises along the first vertical groove 81, releasing the compression of the reset spring 66. The sealing plate 64 is disengaged from the bottle mouth under the rebound action of the reset spring 66, and the air injection head 63 is pulled out. The slide plate 3 continues to move upward, causing the slide rod 91 to enter the inclined groove 82 from the first vertical groove 81. The inclined groove 82 pushes the slide rod 91 to move to the left, causing the slide seat 92 and the gear teeth 93 to move to the left. Since the gear disk 111 is fixed by the limiting component 12 and cannot rotate, the gear teeth 93 are squeezed by the gear disk tooth profile during the leftward movement and rotate back into the slide seat 92. At the same time, the gear teeth 93 compress the first spring 94. When the slide rod 91 slides into the second vertical groove 83, the gear teeth 93 and the tooth groove of the gear disk 111 are re-aligned. The first spring 94 releases its elastic force, pushing the gear teeth 93 to reset and re-engage with the gear disk 111.

[0064] Subsequently, the system repeats the above rotation process, driving the gear disk 111 to transfer the glass bottle that has completed the inspection to the top of the conveying cylinder 116. Under the action of gravity, the glass bottle slides from the threaded limiting cylinder 112 into the conveying cylinder 116 and finally slides out to the next station, completing the entire inspection and sorting cycle, thereby achieving the maintenance of inspection accuracy in high temperature and high humidity environments or low temperature and high humidity environments.

10. A method of using a glass bottle body pressure detection device, comprising the glass bottle body pressure detection device according to any one of claims 1 to 9, characterized in that, Includes the following steps: Step 1: Place the glass bottle inside the threaded limiting cylinder (112). The controller (14) controls the electric telescopic rod (5) to start, so that the electric telescopic rod (5) pulls the connecting plate (4) and drives the slide plate (3) to move downward. The slide rod (91) first moves upward along the second vertical groove (83), and then the electric telescopic rod (5) continues to pull the slide plate (3) downward, so that the slide rod (91) moves along the inclined groove (82), so that the slide rod (91) drives the slide seat (92) to move along the transverse slide rail (21). At the same time, the slide seat (92) drives the gear teeth (93) to push the gear disk (111) to rotate. The rotation of the gear disk (111) drives the glass bottle to move accordingly. Step 2: When the gear disk (111) drives the glass bottle to rotate directly below the gas injection head (63), the gear teeth (93) disengage from the gear teeth of the gear disk (111), and the slide rod (91) slides from the inclined groove (82) into the first vertical groove (81). The temperature sensor (10) is aligned with the glass bottle, so that the temperature sensor (10) transmits the detected temperature of the glass bottle to the controller (14) in real time. At the same time, the humidity sensor (13) on the gear disk (111) transmits the humidity in the device to the controller (14). Then the controller (14) calculates the dynamic maximum allowable pressure drop value according to the temperature and humidity values ​​through the temperature and humidity compensation formula. Step 3: When the gear disk (111) drives the glass bottle to rotate to the directly below of the gas injection head (63), the sliding rod (91) slides into the first vertical groove (81) from the inclined groove (82), and the sliding plate (3) continues to move downward to drive the connecting plate (4) to move along, so that the connecting plate (4) drives the gas injection head (63) to insert into the glass bottle, and also drives the sealing plate (64) to press against the bottle mouth. The connecting plate (4) continues to move downward to compress the telescopic hose (62), while pushing the sliding rod to slide into the sliding cylinder (65), and compressing the return spring (66). The reverse action of the return spring (66) pushes the sliding cylinder (65) to drive the sealing plate (64) to tightly press against the bottle mouth; Step 4: The compressed air tank (7) transports the compressed gas into the telescopic hose (62) through the air pipe (61). The compressed gas enters the gas injection head (63) along the telescopic hose (62), and then the compressed gas is discharged from the gas injection head (63) into the glass bottle. At the same time, the pressure sensor on the air pipe (61) transmits the pressure value to the controller (14) in real time. When the pressure value reaches the threshold for detecting the glass bottle, the injection rate and time of the compressed gas are maintained, and the pressure value is gradually reduced, and the actual pressure drop is calculated; Step 5: When the actual pressure drop ≤ the maximum allowable dynamic pressure drop value, it is judged as qualified, otherwise it is judged as unqualified.
