Description

Technical Field

[0001] The present invention relates to an inspection device, specifically a positive pressure air supply inspection device for the bottle mouth airtightness of glass bottles, belonging to the technical field of glass bottle processing. Background Art

[0002] The current intermittent air supply airtightness detection mechanism generally uses a connected hollow shaft composed of an airtight head and a hollow shaft to move up and down reciprocally to inspect the bottle. When the connected hollow shaft moves downward until the end face of the airtight head presses against the end face of the bottle mouth, at this time, a closed space is formed between the connected hollow shaft and the inner cavity of the bottle. At this time, a positive pressure air pressure is added by an intermittent air pump at one end of the connected hollow shaft. At this time, air pressure is generated in the closed space, and the magnitude of the air pressure is read by an air pressure sensor and transmitted to the computer system.

[0003] A data range is set in the computer, and the value read by the air pressure sensor is compared by the computer. If this value is within the data range set by the computer, it means that the airtightness of the bottle mouth of the bottle being detected at this time is qualified, otherwise it is unqualified. Since the working principle of the intermittent air pump is that a rubber sheet seals the connected hollow shaft into an air tank, and the rubber sheet moves upward under the push of the solenoid valve to reduce the volume of the air tank to increase the air pressure in the connected hollow shaft. It can be seen that the air pressure generated by the intermittent air pump is extremely small.

[0004] In the actual application process. Since the air pressure generated by the intermittent air pump is extremely small. Especially for the detection of large bottles and cans, the error of the value read by the air pressure sensor is very large, and even no value is read. Therefore, missed detections and misjudgments often occur. It not only affects the production capacity of the manufacturer but also wastes the resources of the client. Therefore, there is an urgent need to develop a new airtightness detection mechanism to replace the existing airtightness detection mechanism. Summary of the Invention

[0029] 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.

[0030] Example 1

[0031] This invention discloses a positive pressure gas supply testing device for the sealing performance of glass bottle mouths.

[0032] According to the appendix Figure 1-6 As shown, it includes a long shaft 1, and multiple connecting seats 6, multiple flange linear bearings 7 and multiple bearing sleeves 8 are movably sleeved on the outer surface of the long shaft 1. The connecting seats 6 are fixedly connected between the flange linear bearings 7 and the bearing sleeves 8, and the connecting seats 6 are connected to an external support. A drive mechanism is assembled at the bottom end of the long shaft 1.

[0033] A clamping seat 2 is fitted on the outer surface of the long shaft 1, and a support plate 5 is fixedly connected to the bottom of the clamping seat 2. The support plate 5 is sleeved on the outer surface of the long shaft 1, and a through groove is opened at the other end of the support plate 5. A first hollow shaft 26 is movably inserted into the inner wall of the through groove. A second hollow shaft 11 is fixedly connected to the bottom end of the first hollow shaft 26. A connecting block 16 is movably sleeved at the connection between the first hollow shaft 26 and the second hollow shaft 11. The connecting block 16 is connected to the external support, and the first hollow shaft 26 is equipped with a reset mechanism.

[0034] The bottom end of the second hollow shaft 11 is fixedly installed with an airtight joint 10, and the bottom of the airtight joint 10 is inserted with a glass bottle body 4. The top end of the first hollow shaft 26 is equipped with a three-way joint 25, and the other two ends of the three-way joint 25 are equipped with a first pipe joint 21 and a second pipe joint 22. The end of the first pipe joint 21 is equipped with a pressure sensor 23, and the end of the second pipe joint 22 is equipped with a continuous positive pressure supply air pump 3.

[0035] An air inlet 38 and an air outlet 39 are provided on the front surface of the positive pressure supply air pump 3;

[0036] The air outlet 39 is equipped with an air pipe 24, and the other end of the air pipe 24 is fixedly connected to the second pipe joint 22.

[0037] A dust-proof cover 9 is also fixedly sleeved on the outer surface of the long shaft 1.

[0038] Working principle: During the working process, when the long shaft 1 makes a reciprocating up and down movement, the long shaft 1 can move vertically relative to the connecting seat 6, the flange linear bearing 7 and the bearing sheath 8, so that the support plate 5 clamped on the long shaft 1 pulls the first hollow shaft 26 and the second hollow shaft 11 to make a reciprocating up and down movement, and the first hollow shaft 26 and the second hollow shaft 11 move vertically relative to the connecting block 16;

[0039] When the end face of the airtight joint 10 installed at the bottom end of the second hollow shaft 11 presses against the end face of the bottle mouth of the glass bottle body 4, at this time, a closed space is formed between the first hollow shaft 26 and the second hollow shaft 11 and the inner cavity of the glass bottle body 4. At this time, the air pressure output by the continuous positive pressure supply air pump 3 is connected through the air pipe 24 to the top end of the first hollow shaft 26. At this time, air pressure is generated in the closed space, and the magnitude of the air pressure is transmitted by the first pipe joint 21 to the pressure sensor 23, and is read by the pressure sensor 23 and sent to the computer system. The data range is set in the computer, and the value read by the pressure sensor 23 is compared by the computer. If this value is within the data range set by the computer, it means that the bottle mouth sealing performance of the glass bottle body 4 detected at this time is qualified, otherwise it is unqualified;

[0040] Since the normal working exhaust volume of the continuous positive pressure supply air pump 3 is 10 cubic meters per hour and the normal working air pressure is 4.5 KPa, as long as the first hollow shaft 26 and the second hollow shaft 11 descend to the moment when the end face of the airtight joint 10 presses against the end face of the bottle mouth of the glass bottle body 4, the air pressure in the first hollow shaft 26 and the second hollow shaft 11 instantly reaches 4.5 KPa, and sufficient air pressure can be ensured whether detecting large or small bottles and cans.

[0041] Embodiment Two

[0042] The embodiment of the present invention discloses a positive pressure supply inspection device for the sealing performance of the bottle mouth of a glass bottle.

[0043] According to the appendix Figure 1-6As shown, it includes a long shaft 1, and multiple connecting seats 6, multiple flange linear bearings 7 and multiple bearing sleeves 8 are movably sleeved on the outer surface of the long shaft 1. The connecting seats 6 are fixedly connected between the flange linear bearings 7 and the bearing sleeves 8, and the connecting seats 6 are connected to an external support. A drive mechanism is assembled at the bottom end of the long shaft 1.

[0044] A clamping seat 2 is fitted on the outer surface of the long shaft 1, and a support plate 5 is fixedly connected to the bottom of the clamping seat 2. The support plate 5 is sleeved on the outer surface of the long shaft 1, and a through groove is opened at the other end of the support plate 5. A first hollow shaft 26 is movably inserted into the inner wall of the through groove. A second hollow shaft 11 is fixedly connected to the bottom end of the first hollow shaft 26. A connecting block 16 is movably sleeved at the connection between the first hollow shaft 26 and the second hollow shaft 11. The connecting block 16 is connected to the external support, and the first hollow shaft 26 is equipped with a reset mechanism.

[0045] An airtight connector 10 is fixedly installed at the bottom of the second hollow shaft 11, and a glass bottle body 4 is inserted into the bottom of the airtight connector 10. A three-way connector 25 is installed at the top of the first hollow shaft 26, and a first pipe connector 21 and a second pipe connector 22 are installed at the other two ends of the three-way connector 25. A pressure sensor 23 is installed at the end of the first pipe connector 21, and a continuous positive pressure air pump 3 is installed at the end of the second pipe connector 22.

[0046] The drive mechanism includes a drive seat 35, the top of the drive seat 35 is rotatably connected to the bottom of the long shaft 1, and an eccentric wheel 36 is rotatably connected to the side of the bottom of the drive seat 35. A handwheel shaft 37 is mounted on the end of the eccentric wheel 36 and is rotatably connected to an external bracket.

[0047] The other end of the handwheel shaft 37 is connected to an external drive component, and a limiting component is assembled between the handwheel shaft 37 and the drive seat 35.

[0048] A T-shaped block 17 is fixedly connected to the side of the connecting block 16, and the connecting block 16 is fixedly connected to the outside through the T-shaped block 17. A flange gasket 15, a connecting plate 14 and a bearing sleeve 13 are sequentially assembled at the bottom of the connecting block 16.

[0049] The flange gasket 15, the connecting plate 14 and the bearing sleeve 13 are all movably sleeved on the outer surface of the second hollow shaft 11, and two linear bearings 12 are symmetrically fixedly connected on the inner wall of the bearing sleeve 13. The second hollow shaft 11 is movably inserted into the inner wall of the two linear bearings 12.

[0050] By using the flange gasket 15, connecting plate 14, bearing sleeve 13, and two linear bearings 12, the movement of the second hollow shaft 11 can be limited by the flange gasket 15, connecting plate 14, and bearing sleeve 13, so that the second hollow shaft 11 can only move vertically, thus effectively protecting the second hollow shaft 11.

[0051] The reset mechanism includes a knurled sleeve 19 and a washer 33. The knurled sleeve 19 is fixedly connected to an external bracket and movably sleeved on the outer surface of the first hollow shaft 26. The bottom of the knurled sleeve 19 and the top of the connecting block 16 are both fixedly connected with positioning rubber rings 18, and both positioning rubber rings 18 are movably sleeved on the outer surface of the first hollow shaft 26.

[0052] A bushing 20 is fixedly connected to the top of the knurled sleeve 19. A return spring 34 is fixedly connected between the top of the bushing 20 and the lower surface of the washer 33. Both the bushing 20 and the return spring 34 are movably sleeved on the outer surface of the first hollow shaft 26.

[0053] Washer 33 is fixedly sleeved on the outer surface of the top end of the first hollow shaft 26. The upper surface of washer 33 is equipped with a limiting rubber ring 32 and a washer 31. Both the limiting rubber ring 32 and the washer 31 are movably sleeved on the outer surface of the top end of the first hollow shaft 26.

[0054] The outer surface of the top end of the first hollow shaft 26 is threaded with a first nut 27 and a second nut 30.

[0055] The back of the support plate 5 is provided with an anti-rotation angle iron 28. The top of the anti-rotation angle iron 28 is movably sleeved on the outer surface of the top of the first hollow shaft 26 and is tightly fitted with the first nut 27 and the second nut 30. The front of the anti-rotation angle iron 28 is fixedly connected with an anti-rotation rubber block 29, which is in contact with the back of the support plate 5.

[0056] By setting the anti-rotation angle iron 28 and the anti-rotation rubber block 29, the anti-rotation rubber block 29 is attached to the back of the support plate 5, thereby limiting the movement position of the washer 33, the limiting rubber ring 32, the gasket 31 and the first hollow shaft 26, so that the first hollow shaft 26 can only move vertically and cannot rotate.

[0057] Working principle: During the testing process, after the limiting piece between the handwheel shaft 37 and the drive seat 35 is opened, the drive component connected to the handwheel shaft 37 is activated, and the eccentric wheel 36 can be driven to rotate through the handwheel shaft 37, which in turn can be driven by the drive seat 35 to make up-down reciprocating motion on the long shaft 1.

[0058] When the long shaft 1 drives the support plate 5 to move upward, the washer 33, the limiting rubber ring 32 and the gasket 31 at the top of the first hollow shaft 26 abut against the upper surface of the support plate 5, thus pushing the washer 33, the limiting rubber ring 32 and the gasket 31 to move upward at the same time, which in turn drives the first hollow shaft 26 to move upward relative to the knurled sleeve 19 and the bushing 20. At this time, the return spring 34 is stretched, and at the same time, the second hollow shaft 11 and the airtight joint 10 are pulled upward, so that the airtight joint 10 is separated from the glass bottle body 4 that has been inspected.

[0059] When the long shaft 1 drives the support plate 5 to move downward, the tension return spring 34 contracts and drives the first hollow shaft 26 to move downward through the washer 33, the limiting rubber ring 32 and the shim 31, which in turn pulls the second hollow shaft 11 and the airtight joint 10 to move downward, so that when the end face of the airtight joint 10 presses against the end face of the mouth of another untested glass bottle body 4, the glass bottle body 4 can be tested at this time.

[0060] In summary: During the testing process, after opening the limiting piece between the handwheel shaft 37 and the drive seat 35, the drive component connected to the handwheel shaft 37 is activated, which in turn drives the eccentric wheel 36 to rotate, which in turn drives the long shaft 1 to reciprocate up and down through the drive seat 35.

[0061] When the long shaft 1 drives the support plate 5 to move upward, the washer 33, the limiting rubber ring 32 and the gasket 31 at the top of the first hollow shaft 26 abut against the upper surface of the support plate 5, thus pushing the washer 33, the limiting rubber ring 32 and the gasket 31 to move upward at the same time, which in turn drives the first hollow shaft 26 to move upward relative to the knurled sleeve 19 and the bushing 20. At this time, the return spring 34 is stretched, and at the same time, the second hollow shaft 11 and the airtight joint 10 are pulled upward, so that the airtight joint 10 is separated from the glass bottle body 4 that has been inspected.

[0062] When the long shaft 1 moves the support plate 5 downwards, the tension return spring 34 contracts, and through the washer 33, the limiting rubber ring 32, and the gasket 31, it moves the first hollow shaft 26 downwards, which in turn pulls the second hollow shaft 11 and the airtight connector 10 downwards. This causes the end face of the airtight connector 10 to press against the end face of the mouth of another untested glass bottle body 4. At this point, the first hollow shaft 26 and the second hollow shaft 11 form a sealed space with the inner cavity of the glass bottle body 4. At this time, the top of the first hollow shaft 26 is connected to the continuous positive pressure air pump 3 via the air pipe 24, which outputs air pressure. Air pressure is generated in the sealed space, and the pressure is transmitted to the pressure sensor 23 via the first pipe connector 21. The pressure sensor 23 reads the pressure and sends it to the computer system. A data range is set in the computer, and the value read by the pressure sensor 23 is compared with the data. If the value is within the set data range, the bottle mouth seal of the tested glass bottle body 4 is qualified; otherwise, it is unqualified.

[0063] Since the continuous positive pressure air pump 3 has a normal operating exhaust volume of 10 cubic meters / hour and a normal operating air pressure of 4.5 kPa, as soon as the first hollow shaft 26 and the second hollow shaft 11 descend to the end face of the airtight joint 10 and press against the end face of the bottle body 4, the air pressure inside the first hollow shaft 26 and the second hollow shaft 11 instantly reaches 4.5 kPa, which can ensure sufficient air pressure regardless of the size of the bottle being tested.

[0064] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
