Description

Technical Field

[0001] This application relates to the technical field of glass bottle testing, and in particular to a glass bottle testing device and testing method. Background Technology

[0002] Glass bottles are packaging containers primarily used for beverages, wine, and pharmaceuticals. Determining whether a glass bottle is usable requires efficient testing, such as checking the roundness of the bottle's outer surface, the flatness of the bottle mouth, and the thickness of the bottle wall. When testing the bottle wall thickness, foreign matter adhering to the inner wall can affect the test results; therefore, the inner wall of the bottle must be cleaned before testing.

[0003] Chinese patent application number 201921584597.3 discloses a glass bottle cleaning device, which includes an operating table, a first through pipe, and a glass bottle. A cleaning tank is provided in the middle of the upper surface of the operating table. A support plate is horizontally provided at the lower end of the interior of the cleaning tank. Several sets of positioning rods are vertically fixed on the upper surface of the support plate. Several sets of drainage holes are opened through the upper surface of the support plate. A through groove is vertically opened inside the positioning rod. Several sets of water outlet holes are opened through the inner wall of the through groove. A clean water tank and a disinfection water tank are respectively provided on the left and right sides of the cleaning tank. A first water pump and a second water pump are respectively provided on the inner wall of the right side of the clean water tank and the disinfection water tank. A first solenoid valve and a second solenoid valve are respectively provided inside the first water outlet pipe of the first water pump and the second water outlet pipe of the second water pump. Place the glass bottle upside down on the positioning rod, control the first water pump to work, open the first solenoid valve, and the water in the clean water tank can be discharged through the outlet hole via the first water outlet pipe to further rinse the inner wall of the glass bottle. After cleaning, close the first water pump and the first solenoid valve, open the second water pump and the second solenoid valve, and the disinfectant water in the disinfection tank can be discharged through the outlet hole via the second water outlet pipe to further disinfect the inner wall of the glass bottle. The wastewater after cleaning is discharged to the bottom of the cleaning tank through the drain hole.

[0004] The aforementioned technologies have the following drawbacks: Although water can be discharged through the water outlet and the inner wall of the glass bottle can be rinsed, when a foreign object is facing the water outlet and the water sprayed from the water outlet is vertically sprayed onto the foreign object, the foreign object will be pushed and stick to the inner wall of the glass bottle and cannot fall off quickly, thus affecting the cleaning efficiency of the inner wall of the glass bottle. Summary of the Invention

[0005] In order to overcome the technical problems described in the prior art, this application provides a testing device and testing method for glass bottles.

[0006] Firstly, the glass bottle detection device provided in this application adopts the following technical solution:

[0007] A glass bottle testing device includes a testing platform and a testing instrument mounted on the testing platform. The testing platform is also equipped with a positioning cylinder, and a clamping mechanism for holding the bottle mouth is provided inside the positioning cylinder. A water leakage hole is opened in the positioning cylinder on the testing platform. A hollow support rod is provided in the middle of the positioning cylinder. Multiple nozzles are distributed on the periphery of the support rod. The nozzles are mounted on the support rod with adjustable angles. A water pipe and an air pipe for connecting the nozzles are provided inside the support rod. An adjustment mechanism for adjusting the spray angle of the nozzles is also provided on the support rod.

[0008] Furthermore, a mounting hole is provided through the peripheral wall of the support rod, and a ball joint for connecting the nozzle is provided in the mounting hole. The adjustment mechanism is located inside the support rod, and the output end of the adjustment mechanism is connected to the nozzle, which can drive the nozzle to make yaw and pitch adjustments.

[0009] Furthermore, the adjustment mechanism includes a turntable that is rotatably and vertically mounted within a support rod and a hinge rod that is ball-jointed and mounted on the periphery of the turntable. The end of the hinge rod away from the turntable is hinged to the corner of the nozzle near the end face of the turntable. The hinge rod is inclined on the periphery of the turntable, and the length direction of the hinge rod is set at an angle to the radial direction of the turntable.

[0010] Furthermore, the adjustment mechanism also includes a drive rod coaxially fixed to the turntable, a rotary drive component that drives the drive rod to rotate, and a lifting drive component that drives the rotary drive component to rise and fall synchronously with the drive rod. The lifting drive component is installed below the detection platform.

[0011] Furthermore, the sealing cover between the nozzle and the peripheral wall of the support rod is provided with a flexible cover to prevent water from entering the support rod through the mounting hole.

[0012] Furthermore, multiple turntables, nozzles, and hinge rods are provided along the length of the drive rod.

[0013] Furthermore, the clamping mechanism includes an annular airbag that covers the outer wall of the glass bottle opening.

[0014] Secondly, this application provides a method for detecting glass bottles, based on the aforementioned glass bottle detection device, comprising the following steps:

[0015] S1, glass bottle positioning and clamping, the glass bottle is inverted on the support rod so that the bottle mouth is inserted into the positioning cylinder and the glass bottle is clamped and fixed by the clamping mechanism;

[0016] S2, glass bottle rinsing: High-pressure water is sprayed into the glass bottle through the water pipe, and at the same time the adjustment mechanism is activated. The adjustment mechanism adjusts the spray angle of the nozzle so that the high-pressure water can rinse the inner wall of the glass bottle at different spray angles.

[0017] S3, glass bottle drying: High-pressure airflow is sprayed into the glass bottle through the air tube. At the same time, the adjustment mechanism is activated to adjust the spray angle of the nozzle, so that the high-pressure airflow can sweep the inner wall of the glass bottle at different spray angles, accelerating the downward speed of water droplets on the inner wall of the glass bottle, so that the water droplets on the inner wall of the glass bottle can be quickly discharged through the drain hole.

[0018] S4, Glass bottle inspection: After rinsing and purging, the glass bottle is removed from the positioning cylinder and transferred to the inspection instrument for visual inspection of defects on the inner wall of the glass bottle.

[0019] In summary, the beneficial technical effects of this application are as follows: by adjusting the spray angle of the nozzle through the adjustment mechanism, the nozzle can flush and blow the inner wall of the glass bottle from various angles, ensuring that the inner wall of the glass bottle can be cleaned quickly, improving the cleaning efficiency of the glass bottle, and also ensuring the accuracy of detecting defects on the inner wall of the glass bottle.

[0025] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] This application discloses a testing device and method for glass bottles.

[0027] Reference Figure 1 and Figure 2 A glass bottle inspection device includes an inspection platform 1 and an inspection instrument 2 mounted on the inspection platform 1. The inspection instrument 2 is specifically configured as a glass bottle inspection machine, which performs inspection and analysis on the glass bottle through visual imaging. To avoid low inspection accuracy due to impurities adhering to the inner wall of the glass bottle during inspection, the inner wall of the glass bottle needs to be cleaned before inspection. The inspection platform 1 is provided with multiple cleaning stations, and a positioning cylinder 3 is fixedly installed at each cleaning station. The bottle mouth is inverted and inserted into the positioning cylinder 3. To ensure that the glass bottle is stably inverted, a clamping mechanism 4 for clamping the bottle mouth is provided inside the positioning cylinder 3. In this embodiment, the clamping mechanism 4 includes an annular airbag and an air pump for inflating the annular airbag. The air pump is located below the inspection platform 1 and is connected to the annular airbag through a hose. When it is necessary to clamp and fix the glass bottle, simply insert the bottle mouth upside down into the positioning cylinder 3 and inflate the annular airbag so that the annular airbag covers the outer wall of the bottle mouth. At this time, the glass bottle can be stably placed upside down on the detection platform 1 under the wrapping of the annular airbag.

[0028] Reference Figure 1 , Figure 2 and Figure 3 A support rod 6 is vertically fixed inside the positioning cylinder 3 on the testing platform 1. The support rod 6 is coaxially installed in the positioning cylinder 3, and its bottom end extends downward through the platform surface of the testing platform 1. The support rod 6 is hollow, so when the glass bottle is stably inverted on the testing platform 1, the support rod 6 extends into the glass bottle. Multiple mounting holes 9 are provided through the periphery of the support rod 6. The number of mounting holes 9 can be determined according to the size of the glass bottle. In this embodiment, four mounting holes 9 are arranged around the same height of the support rod 6, and a total of six mounting holes 9 are provided in the vertical direction of the support rod 6. A ball joint 10 is provided on the top wall inside the mounting hole 9. A nozzle 7 is connected to each mounting hole 9 through the ball joint 10. The nozzle 7 can be adjusted for tilting and pitching within the mounting hole 9. The support rod 6 also houses a water pipe and an air pipe for connecting the nozzle 7. Both the water pipe and the air pipe are made of flexible material. The water pipe is connected to a water source, allowing the nozzle 7 to spray high-pressure water to flush the inner wall of the glass bottle. The air pipe is connected to an air source, allowing the nozzle 7 to spray high-pressure air to blow away the inner wall of the glass bottle. To ensure that the water on the inner wall of the glass bottle can be quickly drained during blowing, multiple drainage holes 5 are provided inside the positioning cylinder 3 on the detection platform 1, and all drainage holes 5 are arranged around the outside of the support rod 6.

[0029] To facilitate convenient adjustment of the tilt and pitch angles of nozzle 7, refer to Figure 2 , Figure 3 and Figure 4 The support rod 6 is also equipped with an adjustment mechanism for adjusting the spray angle of the nozzle 7, and the adjustment mechanism is located inside the support rod 6. The adjustment mechanism includes multiple turntables 81 that are rotatably and vertically arranged inside the support rod 6, multiple hinge rods 82 that are ball-jointed and mounted around the turntables 81, a drive rod 83 that is coaxially fixed to the multiple turntables 81, a rotary drive member 84 that drives the drive rod 83 to rotate, and a lifting drive member 85 that drives the rotary drive member 84 to rise and fall synchronously with the drive rod 83. In this embodiment, there are six turntables 81, and the six turntables 81 correspond one-to-one with the six mounting holes 9 in the vertical direction of the support rod 6. There are four hinge rods 82 around the same turntable 81, and the four hinge rods 82 correspond one-to-one with the four mounting holes 9 arranged around the support rod 6 at the same height. The hinge rod 82 is inclinedly arranged on the periphery of the turntable 81. The end of the hinge rod 82 away from the turntable 81 is hinged to the corner of the nozzle 7 near the end face of the turntable 81, and the length direction of the hinge rod 82 is set at an angle to the radial direction of the turntable 81. A receiving box is provided below the detection platform 1. The lifting drive component 85 is a cylinder, which is vertically fixed in the receiving box. The rotation drive component 84 is a motor, which is fixed on the output end of the cylinder. The bottom end of the drive rod 83 extends downward through the platform surface of the detection platform 1 and is coaxially fixed to the output end of the motor. When the lifting drive 85 drives multiple turntables 81 to rise and fall synchronously via the drive rod 83, the turntables 81 drive the nozzles 7 to adjust their pitch within the mounting holes 9 via the hinge rods 82 on their periphery; when the rotation drive 84 drives multiple turntables 81 to rotate synchronously via the drive rod 83, the turntables 81 drive the nozzles 7 to adjust their yaw within the mounting holes 9 via the hinge rods 82 on their periphery; with the pitch and yaw adjustment of the nozzles 7, high-pressure water or high-pressure airflow can be sprayed at different angles to flush or blow the inner wall of the glass bottle, ensuring that the inner wall of the glass bottle can be cleaned quickly, improving the cleaning efficiency of the glass bottle, and also ensuring the accuracy of detecting defects on the inner wall of the glass bottle.

[0030] To prevent water from entering the support rod 6 through the mounting hole 9 and causing damage to the rotary drive component 84 and the lifting drive component 85, refer to... Figure 2 The sealing cover between the nozzle 7 and the periphery of the support rod 6 is provided with a flexible cover 11 to prevent water from entering the support rod 6 through the mounting hole 9. The flexible cover 11 can be made of rubber or can be set as a bellows cover. Considering that the angle adjustment range of the nozzle 7 is small, the flexible cover 11 is set as a sealing cover made of rubber.

[0031] This application provides a method for testing glass bottles, which adopts the following technical solution:

[0032] S1, glass bottle positioning and clamping, the glass bottle is inverted on the support rod 6 so that the bottle mouth is inserted into the positioning cylinder 3 and the glass bottle is clamped and fixed by the clamping mechanism 4;

[0033] S2, glass bottle rinsing: High-pressure water is sprayed into the glass bottle through the water pipe, and the adjustment mechanism is activated at the same time. The adjustment mechanism adjusts the spray angle of the nozzle 7 so that the high-pressure water can rinse the inner wall of the glass bottle at different spray angles.

[0034] S3, the glass bottle is dried by spraying high-pressure airflow into the glass bottle through the air tube. At the same time, the adjustment mechanism is activated to adjust the spray angle of the nozzle 7, so that the high-pressure airflow can sweep the inner wall of the glass bottle at different spray angles, accelerate the downward speed of water droplets on the inner wall of the glass bottle, and allow the water droplets on the inner wall of the glass bottle to be quickly discharged through the drain hole 5.

[0035] S4, glass bottle inspection: After rinsing and purging, the glass bottle is removed from the positioning cylinder 3 and transferred to the inspection instrument 2 for visual inspection of defects on the inner wall of the glass bottle.

[0036] The implementation principle of the glass bottle detection device and method in this application embodiment is as follows: First, the glass bottle is inverted on the support rod 6, so that the bottle mouth is inserted into the positioning cylinder 3, and the annular airbag is inflated, so that the annular airbag covers the outer wall of the bottle mouth. At this time, the glass bottle can be stably inverted on the detection platform 1 under the wrapping of the annular airbag. Next, high-pressure water is sprayed into the glass bottle through the water pipe, and at the same time, the rotary drive 84 and the lifting drive 85 are activated. The rotary drive 84 and the lifting drive 85 adjust the spray angle of the nozzle 7, so that the high-pressure water can rinse the inner wall of the glass bottle at different spray angles. Then, high-pressure airflow is sprayed into the glass bottle through the air pipe, and at the same time, the rotary drive 84 and the lifting drive 85 are activated. The rotary drive 84 and the lifting drive 85 adjust the spray angle of the nozzle 7, so that the high-pressure airflow can blow the inner wall of the glass bottle at different spray angles, accelerating the downward speed of water droplets on the inner wall of the glass bottle, so that the water droplets on the inner wall of the glass bottle can be quickly discharged through the drain hole 5. Finally, the rinsed and purged glass bottle is removed from the positioning cylinder 3 and transferred to the inspection instrument 2 for visual inspection of defects on the inner wall of the glass bottle.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
