Technical Field
[0001] This invention belongs to the field of container impact strength testing technology, and particularly relates to a glass bottle impact resistance testing device and testing method. Background Technology
[0002] Glass bottles are a traditional beverage packaging container in my country. Despite the influx of many other packaging materials into the market, glass containers still occupy an important position in beverage packaging, which is inseparable from their packaging characteristics that cannot be replaced by other packaging materials.
[0003] In the beer and beverage industry, the impact resistance of glass bottles is a key quality control indicator. Glass bottles shatter upon impact primarily due to the combined effect of the glass's inherent fragility and internal pressure changes. When a glass bottle is subjected to external impact, stress concentration easily occurs at the neck and bottom, potentially creating microcracks that reduce the bottle's compressive strength. These cracks then propagate rapidly, eventually leading to breakage. Uneven bottle wall thickness or the presence of air bubbles also increases the risk of explosion. To prevent quality risks such as bottle breakage due to external impacts, GB 4544-2020 "Beer Bottles" requires testing the impact resistance of both recyclable new and used bottles.
[0004] Currently, food and beverage companies use beer bottle impact testers to conduct the aforementioned tests. The specific procedure involves an operator placing a single sample bottle at the testing station, manually adjusting the pendulum to a preset angle, and then releasing it. The operator visually inspects the bottle for breakage after impact and manually enters the results into the system. However, these beer bottle impact testers have the following problems: each sample bottle requires manual handling, resulting in a long testing cycle; relying on manual visual inspection to determine bottle breakage and input impact results introduces human intervention, affecting the objectivity of data collection and reducing testing efficiency; and the flying glass shards from the pendulum breaking the sample bottle pose a safety hazard to the operator. Summary of the Invention
[0005] This invention addresses the technical problems of current beer bottle impact testers, such as long testing cycles, low testing efficiency, data acquisition objectivity being affected by human factors, and safety hazards caused by glass breakage and splashing. It proposes a glass bottle impact testing device and method. The testing device has a relatively simple structure and is easy to operate. An automatic sample feeding mechanism delivers the sample to the testing station, and a feedback mechanism transmits the impact results to the control mechanism, ensuring the objectivity and accuracy of the testing data. This makes the entire impact testing process, from data detection and acquisition to conclusions, information-based, improving work efficiency and data objectivity. The testing method automatically feeds the sample bottle, automatically detects and judges the impact results, and accurately uploads the test data, reducing manual intervention and significantly improving work efficiency. Furthermore, during the testing process, operators can stay away from the impact area, effectively eliminating the safety risks of glass breakage and splashing that could injure them.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a glass bottle impact resistance testing method, comprising a workbench, including a workbench surface and a support structure disposed on the workbench surface; a sample injection mechanism disposed on the workbench surface for automatically injecting the sample bottle to be tested into the testing station; an impact mechanism disposed on the support structure for striking the sample bottle to be tested located at the testing station with a set impact force; a detection feedback mechanism disposed on the workbench surface for detecting and providing feedback on the impact result of the sample bottle to be tested; and a control mechanism electrically connected to the sample injection mechanism and the detection feedback mechanism for controlling each mechanism to perform corresponding actions.
[0007] In some embodiments, the sample introduction mechanism includes a turntable disposed on a worktable, the turntable having multiple sample placement positions evenly distributed circumferentially for simultaneously carrying multiple sample vials to be tested; a turntable drive motor electrically connected to a control mechanism for driving the turntable to rotate, thereby sequentially transporting the sample vials to be tested placed at the sample placement positions to the testing station; a clamping component disposed on the turntable for fixing the sample vials to be tested; a height adjustment component detachably disposed at the bottom of the turntable for adjusting the sample vials to be tested to the testing height; a positioning magnet disposed on the turntable corresponding to the testing station; and a positioning magnetic switch disposed on the worktable for detecting whether the positioning magnet has reached the testing station.
[0008] In some embodiments, the impact mechanism includes a pendulum link rotatably connected to a support structure via a bearing; and a pendulum disposed at the end of the pendulum link away from the support structure.
[0009] In some embodiments, the detection feedback mechanism is disposed on the swing trajectory of the pendulum link and includes a signal transceiver component and a signal reflection component. The signal transceiver component continuously transmits signals and detects the signals returned by the signal reflection component.
[0010] In some embodiments, a drive mechanism is also included, which is mounted on the support structure and connected to the impact mechanism, for driving the impact mechanism to a preset position. The drive mechanism is electrically connected to the control mechanism. A recycling mechanism is located at the bottom of the worktable for collecting broken glass generated during the testing process.
[0011] In some embodiments, the driving mechanism includes a pendulum driving assembly for driving the pendulum and pendulum connecting rod to a preset position. The pendulum driving assembly further includes: a dial, disposed on the worktable, for indicating the lifting angle of the pendulum; a control motor, disposed on the worktable and electrically connected to the control mechanism; a first control gear, disposed on the dial; a second control gear, meshing with the first control gear; a control connecting rod, fixed on the dial and coaxially rotatable with the pendulum connecting rod; and an electromagnet, disposed at the end of the control connecting rod away from the dial.
[0012] In another aspect, the present invention provides a method for testing the impact resistance of glass bottles, applied to the glass bottle impact resistance testing device, comprising the following steps: Sample delivery steps: The sample delivery mechanism sequentially delivers multiple sample vials to be tested to the testing station; Impact testing procedure: The control mechanism controls the impact mechanism to strike the sample bottle to be tested located at the testing station; Result feedback step: The detection feedback mechanism feeds back the results to the control mechanism based on the detection signal.
[0013] In some embodiments, the sample delivery step specifically includes: Place multiple sample vials to be tested into the sample placement positions on the sample inlet turntable; The control mechanism commands the turntable drive motor to start, causing the turntable to rotate. When the positioning magnetic switch detects that the positioning magnet is in place, it sends a feedback signal to the control mechanism, and the turntable stops rotating, allowing the test sample bottle to arrive at the testing station. After the impact test is completed, the control mechanism restarts the turntable drive motor to send the next sample bottle to be tested into the testing station, until the preliminary test of the entire batch of sample bottles is completed.
[0014] In some embodiments, the impact detection step specifically includes: The control mechanism commands the control lever of the drive mechanism to move, causing the electromagnet to move to the attraction position and attract the pendulum. The drive mechanism moves the pendulum and pendulum linkage to a preset position and then stops. After the sample injection mechanism transports the sample bottle to be tested to the testing station, the electromagnet releases the pendulum, which swings with the pendulum link and strikes the sample bottle to be tested with a preset impact force. After the impact is completed, the drive mechanism drives the pendulum and pendulum connecting rod to return to the preset position.
[0015] In some embodiments, the result feedback step specifically includes: The detection feedback mechanism continuously emits infrared rays and receives the reflected infrared rays; When the pendulum strikes the sample bottle to be tested, if the sample bottle is not broken, the detection feedback mechanism continuously receives the reflected infrared light, determines the result as qualified, and feeds the result back to the control mechanism. If the sample vial is broken, the pendulum link will instantly block the reflected infrared light, and the detection feedback mechanism will determine the result as unqualified and send the result back to the control mechanism.
[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows: (1) The glass bottle impact resistance testing device of the present invention has a simple structure and is easy to operate. The sample is automatically fed to the testing station through the sample feeding mechanism. The testing feedback mechanism feeds back the impact result of the impact mechanism to the control mechanism, realizing the objectivity and accuracy of the testing process data. This makes the impact resistance test from data detection, collection and conclusion information-based, improving work efficiency and ensuring the objectivity and authenticity of the test data.
[0017] (2) The glass bottle impact resistance test method of the present invention automatically feeds the sample bottle to be tested, automatically detects and judges the impact results of the sample bottle, and accurately uploads the test data, which reduces manual intervention and greatly improves work efficiency. At the same time, the operator can stay away from the area where the glass bottle is hit during the test, which effectively eliminates the safety risk of the glass bottle breaking and splashing and injuring the operator during the test.

Detailed Implementation
[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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.
[0020] This invention provides a glass bottle impact resistance testing device and method. The testing device has a relatively simple structure and is easy to operate. The sample introduction mechanism 200 automatically introduces the sample to the testing station, and the detection feedback mechanism 500 feeds back the impact results from the impact mechanism 300 to the control mechanism 600, ensuring the objectivity and accuracy of the testing process data. This makes the entire impact resistance testing process, from data detection and acquisition to conclusions, information-based, improving work efficiency and data objectivity and authenticity.

[0021] Reference Appendix Figure 1As shown, the glass bottle impact resistance testing device of this invention includes a workbench 100; a sample feeding mechanism 200, disposed on the workbench 100, for automatically feeding a batch of sample bottles to be tested to the testing station; an impact mechanism 300, disposed on the workbench 100, configured to strike the sample bottle to be tested located at the testing station with a set impact force; a drive mechanism 400, disposed on the workbench 100 and connected to the impact mechanism 300, for driving the impact mechanism 300 to a preset position; a detection feedback mechanism 500, disposed on the workbench 100, for detecting the impact effect of the sample bottle to be tested and feeding the result back to the control mechanism 600; the control mechanism 600, electrically connected to the sample feeding mechanism 200, the drive mechanism 400 and the detection feedback mechanism 500, for controlling each mechanism to perform corresponding actions; and a recovery mechanism 700, disposed at the bottom of the workbench 100, for collecting broken glass generated during the testing process to avoid glass splattering and polluting the environment or causing personnel cuts.
[0022] refer to Figures 1-5As shown, the workbench 100 of this embodiment includes a workbench surface 110 and a support structure 120 disposed on the workbench surface 110; the sample feeding mechanism 200 includes a turntable 210 disposed on the workbench surface 110, the turntable 210 having multiple sample placement positions evenly distributed circumferentially for simultaneously carrying multiple sample vials to be tested; a turntable drive motor 220, electrically connected to the control mechanism 600, for driving the turntable 210 to rotate, so as to sequentially transport the sample vials to be tested placed at the sample placement positions to the testing station; a clamping component 230, disposed on the turntable 210, for fixing the sample vials to be tested, ensuring that the sample vials to be tested rotate and swing on the turntable 210. The hammer 320 remains stable during impact; the height adjustment component 240, detachably mounted at the bottom of the turntable 210, is used to replace or adjust the height according to the type of sample bottle (e.g., 640 bottles, 600 bottles, 500 bottles, 318 bottles, etc.) to ensure that the pendulum 320 of the impact mechanism 300 accurately strikes the bottle shoulder position required by national standards when the sample bottle to be tested is in the testing station; the positioning magnet 250 is set on the turntable 210 at the position corresponding to the testing station; the positioning magnetic switch 260 is set on the worktable 110 and electrically connected to the control mechanism 600. When the turntable 210 rotates so that the positioning magnet 250 is directly facing the positioning magnetic switch 260, a positioning signal is triggered. When the turntable drive motor 220 drives the turntable 210 to rotate, and the positioning magnetic switch 260 detects that the positioning magnet 250 is in position, it indicates that the sample bottle to be tested has accurately reached the testing station. The positioning magnetic switch 260 sends a signal to the control mechanism 600, and the control mechanism 600 then instructs the turntable drive motor 220 to stop rotating. During operation, the control mechanism 600 instructs the turntable drive motor 220 to start, driving the turntable 210 to rotate. The positioning magnetic switch 260 detects that the positioning magnet 250 is in place and sends a feedback signal to the control mechanism 600, causing the turntable 210 to stop rotating. The sample bottle to be tested then accurately reaches the testing station. After the impact mechanism 300 completes one impact, the control mechanism 600 restarts the turntable drive motor 220 to send the next sample bottle to be tested into the testing station, until the preliminary testing of the entire batch (e.g., 12) of sample bottles is completed.
[0023] refer to Figure 1 As shown in Figures 2, 3, 6, and 7, the impact mechanism 300 of this embodiment includes a pendulum link 310, which is rotatably connected to the support structure 120 via a bearing; a pendulum 320 is disposed at the end of the pendulum link 310 away from the support structure 120. The pendulum 320 is configured to swing with the pendulum link 310 under the action of gravity, striking the sample bottle to be tested at the testing station with a set impact force. In the initial state, the pendulum 320 and the pendulum link 310 hang naturally under the action of gravity; the bearing is preferably a ball bearing, which can reduce the frictional resistance when the pendulum link 310 swings, ensuring that the pendulum 320 can swing smoothly and sensitively with the pendulum link 310, reducing energy loss and improving the reliability of the test results.
[0024] refer to Figure 1 As shown in Figures 2, 3, 6, and 7, the driving mechanism 400 of this embodiment includes a pendulum driving assembly 410, used to precisely drive the pendulum 320 and the pendulum connecting rod 310 to a predetermined position that meets the test standard. The pendulum driving assembly 410 further includes: a scale 411, disposed on the support structure 120, used to indicate the lifting angle of the pendulum 320; a control motor 412, disposed on the support structure 120, and electrically connected to the control mechanism 600; a first control gear 413, disposed on the scale 411; a second control gear 414, meshing with the first control gear 413; a control connecting rod 415, fixed on the scale 411, and coaxially disposed with the pendulum connecting rod 310; and an electromagnet 416, disposed at the end of the control connecting rod 415 away from the scale 411. Initially, the pendulum 320 and pendulum connecting rod 310 hang naturally under gravity. During operation, the control motor 412 receives a signal from the control mechanism 600 and drives the second control gear 414 to rotate. The second control gear 414 then drives the first control gear 413 to rotate. The first control gear 413, in turn, drives the scale 411, the control connecting rod 415 fixed on the scale 411, and the electromagnet 416 fixed to the top of the control connecting rod 415 to rotate counterclockwise to a vertical position. When the electromagnet 416 contacts the pendulum 320, it is immediately energized and attracts the pendulum 320. Subsequently, the control motor 412, according to the program signal from the control mechanism 600, drives the second control gear 414 to rotate. The second control gear 414 drives the first control gear 413, which in turn drives the scale 411, the control connecting rod 415, and the electromagnet 416 to rotate clockwise, thereby rotating the pendulum 320... 20 and the pendulum connecting rod 310 connecting the pendulum 320 move together to a preset position that meets the national standard requirements and stop; after the sample injection mechanism 200 transports the sample bottle to be tested to the testing station, the electromagnet 416 is de-energized, and the pendulum 320 and pendulum connecting rod 310, which lose their attraction force, swing counterclockwise around the bearing of the pendulum 320 under the action of gravity, striking the sample bottle to be tested with a set impact force. The detection feedback mechanism 500 then judges the impact test result and sends the result back to the test station. Feedback is sent to the control mechanism 600; after the impact is completed, the pendulum 320 and pendulum connecting rod 310 naturally droop back to the lowest point under the action of gravity. The control mechanism 600 instructs the drive mechanism 400 to move the electromagnet 416 to the lowest point position. The electromagnet 416 is energized again to attract the pendulum 320, and the control motor 412 drives the pendulum drive assembly 410 to reset the pendulum 320 and pendulum connecting rod 310 clockwise to the preset position required by the national standard, waiting for the next test.
[0025] refer to Figure 5As shown, the installation height of the detection feedback mechanism 500 in this embodiment of the invention is 150mm~200mm from the bottom surface of the sample bottle, and the horizontal offset of the detection feedback mechanism 500 relative to the vertical release position of the pendulum link 310 is 3mm~10mm. The detection feedback mechanism 500 includes a signal transceiver component 510 and a signal reflection component 520. The signal transceiver component 510 continuously transmits signals and detects the signals returned by the signal reflection component 520. In a preferred embodiment, the detection feedback mechanism 500 is disposed on one side of the sample bottle to be tested, and its optical path is located on the swing trajectory of the pendulum link 310, and is offset from the sample bottle itself by a certain distance to avoid interference caused by normal reflection from the surface of the sample bottle. The signal transceiver unit 510 continuously emits infrared rays. When the impact mechanism 300 strikes the sample bottle to be tested, if the sample bottle is not broken, the signal transceiver unit 510 can continuously receive the infrared rays reflected back by the signal reflection component 520 and feed the result back to the control mechanism 600, recording that the sample bottle to be tested is qualified. If the sample bottle to be tested is broken, the pendulum connecting rod 310 instantly blocks the infrared rays reflected back by the signal reflection component 520 and feeds the result back to the control mechanism 600, recording that the sample bottle to be tested is unqualified.
[0026] refer to Figure 1-3 As shown, the control mechanism 600 of this embodiment includes a display control interface 610, used to receive signals transmitted by the detection feedback mechanism 500, precisely control the drive mechanism 400 to set the impact force action according to a preset program or operator instructions, and control the sample injection mechanism 200 to complete automatic sample delivery. According to national standards, each sample bottle needs to be impacted at three 120° angle positions. Therefore, after each set of sample bottles is tested, the display control interface 610 will pop up a "Confirm Result" dialog box. After confirmation, it will prompt "Do you need to adjust the sample bottle angle?" After adjusting the sample bottle to rotate 120°, the next set of operations will be started until all three angles have been impacted.
[0027] refer to Figure 1-3 As shown, the recycling mechanism 700 of this embodiment includes a base cabinet and a collection container 720 disposed inside the base cabinet. During the experiment, if the sample bottle to be tested is broken, the broken glass enters the collection container 720 inside the base cabinet through the collection port opened at the bottom of the turntable 210, effectively preventing broken glass from splashing and polluting the environment or causing the risk of cuts to personnel.
[0028] The glass bottle impact resistance testing device of the present invention has a relatively simple structure and is easy to operate. The sample is automatically fed to the testing station through the sample feeding mechanism 200, and the detection feedback mechanism 500 feeds back the impact result of the impact mechanism 300 to the control mechanism 600, so as to realize the objectivity and accuracy of the test process data, and make the entire process of impact resistance testing from data detection, collection and conclusion information-based, thereby improving work efficiency and data objectivity and authenticity.
[0029] This invention provides a method for testing the impact resistance of glass bottles, applied to a glass bottle impact resistance testing device, specifically including the following steps: S1. Sample transport procedure S11. After entering the identification information of multiple sample bottles to be tested into the system, place them in the sample placement positions of the turntable 210 of the sample injection mechanism 200, and use the clamping component 230 to fix the corresponding sample bottles to be tested to prevent shaking during the rotation or impact of the turntable 210; according to the type of sample bottle, select an appropriate height adjustment component 240 and install it in the sample placement position of the turntable 210 to adjust the height of the sample bottle to be tested, so as to ensure that the pendulum 320 can accurately hit the bottle shoulder position required by the national standard. S12. The control mechanism 600 commands the turntable drive motor 220 to start, and the turntable drive motor 220 drives the turntable 210 to rotate. When the turntable 210 rotates to the point where the positioning magnet 250 is directly opposite the positioning magnetic switch 260 set on the worktable surface 110, the positioning magnetic switch 260 detects that the positioning magnet 250 is in place and immediately sends a feedback signal to the control mechanism 600, and the turntable 210 stops rotating. At this time, one of the sample bottles to be tested accurately reaches the testing station. S13. After the impact test step is completed, the control mechanism 600 restarts the turntable drive motor 220 to send the next sample bottle to be tested into the test station. The above process is repeated until the preliminary test of the entire batch of sample bottles is completed. After completing the impact test of a set of the entire batch of sample bottles, the "Confirm Result" dialog box popped up on the display control interface 610 is used for confirmation. The sample bottle is rotated 120° and the next set of operations is started until each sample bottle is hit at three 120° angle positions. S2. Impact Detection Procedure S21. The control mechanism 600 commands the control motor 412 of the drive mechanism 400 to start, driving the second control gear 414 to rotate. The second control gear 414 drives the first control gear 413 meshing with it to rotate. The first control gear 413 then drives the dial 411, the control linkage 415 fixed on the dial 411, and the electromagnet 416 fixed on the top of the control linkage 415 to rotate counterclockwise together. When the control linkage 415 rotates to the vertical position, the electromagnet 416 just contacts the pendulum 320 in a naturally drooping state. At this time, the control mechanism 600 commands the electromagnet 416 to be energized. The electromagnet 416 generates magnetic force and firmly attracts the pendulum 320. S22. The control mechanism 600 sends a second command to the control motor 412 according to the preset program. The control motor 412 drives the second control gear 414 to rotate clockwise. The second control gear 414 drives the first control gear 413. The first control gear 413 drives the dial 411, the control link 415, and the electromagnet 416 with the pendulum 320 attached to it to continue rotating clockwise. During this process, the pendulum 320 and the pendulum link 310 connected to it are lifted together. When the angle indicated by the dial 411 reaches the preset position, the control motor 412 stops rotating, and the pendulum 320 and the pendulum link 310 remain at that position. The preset position is the highest point on the left side of the dial 411. It is set according to the specific requirements of different glass bottles. According to GB 4544-2020 "Beer Bottles", the preset value of the impact resistance of a recyclable new bottle with a volume greater than 530mL should be greater than 0.6J; the preset value of the impact resistance of a recyclable new bottle with a volume less than 530mL should be greater than 0.4J. S23. After the control mechanism 600 confirms that the sample injection mechanism 200 has transported the sample bottle to be tested to the testing station, it commands the electromagnet 416 to be de-energized. The electromagnet 416 loses its magnetic force, and the pendulum 320 and the pendulum connecting rod 310 swing counterclockwise around the pendulum 320 bearing under the action of gravity, striking the shoulder of the sample bottle to be tested with the set impact force. S24. After the impact is completed, the pendulum 320 and pendulum connecting rod 310 naturally droop back to the lowest point under the action of gravity. The control mechanism 600 instructs the drive mechanism 400 to move the electromagnet 416 to the lowest point position. Then, the electromagnet 416 is energized again, attracting the pendulum 320. Finally, the control motor 412 drives the second control gear 414 to rotate clockwise, and the pendulum 320 and pendulum connecting rod 310 are reset clockwise to the preset position through gear transmission, waiting for the next test. S3. Results Feedback Steps S31. The detection feedback mechanism 500 continuously emits infrared rays and receives the reflected infrared rays; S32. When the pendulum 320 strikes the sample bottle to be tested, if the sample bottle is not broken, the detection feedback mechanism 500 continuously receives the reflected infrared light, determines the result as qualified, and feeds the result back to the control mechanism 600. S33. If the sample vial is broken, the pendulum link 310 will instantly block the reflected infrared light, and the detection feedback mechanism 500 will determine the result as unqualified and feed the result back to the control mechanism 600.
[0030] The glass bottle impact resistance test method of this invention also includes a data verification step, which involves manually screening qualified sample bottles for cracks. For sample bottles with obvious cracks after testing, it is allowed to manually modify the interface to correct them as cracks in the summarized test results.
[0031] To provide a clearer and more detailed description of the glass bottle impact resistance testing method and apparatus provided in the embodiments of the present invention, the following description will be based on specific embodiments.
[0032] Example 1 The impact resistance test method for glass bottles in this embodiment includes the following steps: S1. Enter the batch numbers of 12 sample bottles to be tested into the system, and then place the sample bottles to be tested on the sample placement positions of the turntable 210, fix them with clamping parts 230, and adjust the height of the sample bottles to be tested by height adjustment parts 240 to ensure that the pendulum 320 can accurately strike the bottle shoulder position required by national standards; the control mechanism 600 instructs the turntable drive motor 220 to start, and the turntable drive motor 220 drives the turntable 210 to rotate until the positioning magnet 250 is directly facing the positioning magnetic switch 260 set on the worktable 110. The positioning magnetic switch 260 detects that the positioning magnet 250 is in place, and then sends a feedback signal to the control mechanism 600. The turntable 210 stops rotating. At this time, one of the sample bottles to be tested has accurately reached the testing position. S2. The control mechanism 600 commands the control motor 412 of the drive mechanism 400 to start, driving the second control gear 414 to rotate, which in turn drives the first control gear 413 meshing with it to rotate, thereby causing the scale 411, the control linkage 415 fixed on the scale 411, and the electromagnet 416 fixed to the top of the control linkage 415 to rotate counterclockwise. When the control linkage 415 rotates to the vertical position, the electromagnet 416 just contacts the pendulum 320 in a naturally drooping state. At this time, the control mechanism 600 commands the electromagnet 416 to be energized, and the electromagnet 416 generates magnetic force and firmly attracts the pendulum 320. The control mechanism 600 sends a second command to the control motor 412 according to the preset program, and the control motor 412 drives the second control gear 414 to rotate clockwise. The second control gear 414 drives the first control gear 413, and the second control gear 414 rotates clockwise. A control gear 413 drives the dial 411, control linkage 415, and electromagnet 416 with the pendulum 320 attached to it to continue rotating clockwise. During this process, the pendulum 320 and the pendulum linkage 310 connected to it are lifted together. When the angle indicated by the dial 411 reaches the preset position, the control motor 412 stops rotating, and the pendulum 320 and the pendulum linkage 310 remain in that position. After the control mechanism 600 confirms that the sample injection mechanism 200 has transported the sample bottle to be tested to the testing station, it commands the electromagnet 416 to be de-energized. The electromagnet 416 loses its magnetic force, and the pendulum 320 and the pendulum linkage 310 swing counterclockwise around the pendulum 320 bearing under the action of gravity, striking the shoulder of the sample bottle to be tested with a set impact force. After the impact is completed, the pendulum 320 and the pendulum linkage 310 naturally hang down to the lowest point again under the action of gravity. The control mechanism 600 instructs the drive mechanism 400 to move the electromagnet 416 to the lowest point position. Then the electromagnet 416 is energized again, attracting the pendulum 320. Finally, the control motor 412 drives the second control gear 414 to rotate clockwise, and the pendulum 320 and pendulum connecting rod 310 are reset clockwise to the preset position through gear transmission, waiting for the next test. S3. When the pendulum 320 strikes the sample bottle to be tested, if the sample bottle is not broken, the detection feedback mechanism 500 continuously receives the reflected infrared light, determines the result as qualified, and feeds the result back to the control mechanism 600 to continue testing the next sample bottle. After all 12 sample bottles have been tested, the "Confirm Result" dialog box that pops up on the display control interface 610 is used for confirmation. The sample bottle is then rotated 120° and the next set of operations is started, until each sample bottle has been struck at three 120° angle positions.
[0033] S4. After testing, the sample bottles were manually screened for cracks. None of the 12 sample bottles in this group had obvious cracks. After confirming that the 12 sample bottles to be tested simultaneously met the conditions of passing the test and having no obvious cracks, the data was uploaded to the server and archived in the data analysis system.
[0034] Comparative Example 1 This comparative example uses a glass bottle impact tester to test 12 sample bottles according to the national standard "GB / T6552-2015 Glass Containers Mechanical Impact Resistance Test Method". The model of the glass bottle impact tester is KCJ-1.
[0035] In both Example 1 and Comparative Example 1, Example 1 took a total of 12 minutes, requiring no manual intervention except for manual confirmation of the start and end of the test. During the test, the testing personnel could perform other tasks concurrently. Comparative Example 1 took a total of 15 minutes, requiring manual intervention throughout. Compared to Comparative Example 1, Example 1 uses the glass bottle impact resistance testing device of this invention to conduct impact tests on glass bottles. It can effectively achieve automatic sample loading, automatic detection and result judgment of the impact test results, and the accuracy of detection and data upload is 100%, ensuring the objectivity of the glass bottle impact resistance test data. The manual intervention time in Example 1 is 1 / 10 of that in Comparative Example 1, significantly improving work efficiency. Moreover, during the test, the operator can stay away from the area where the glass bottle is impacted, effectively eliminating the safety risk of injury to the operator due to glass bottle breakage and splashing as in Comparative Example 1.
