Description

Technical Field

[0001] The present application relates to the technical field of air tightness detection, and in particular to a bottle detection tool. Background Art

[0002] After the production of various bottles is completed, they need to be aligned and tested for sealing, as shown in the attached Figure 1 The bottle body is usually used as a PP water purification bottle or a gas storage bottle, etc., including a bottle cap 02, a bottle body 01 and a rotating cover 03. The bottle cap 02 and the bottle body 01 are generally connected by spin melting or other welding processes. The rotating cover 03 is installed in the protruding part of the bottle cap 02 and is sealed by a sealing ring. The rotating cover 03 is provided with a one-way air hole 031. Usually, the connection between the bottle body 01 and the bottle cap 02, and the connection between the rotating cover 03 and the bottle cap 02 of this bottle body need to be tested for sealing. Usually, the sealing test of the connection between the bottle body 01 and the bottle cap 02, and the connection between the rotating cover 03 and the bottle cap 02 usually needs to be tested separately, and it is necessary to manually insert air columns into the one-way air holes 031 one by one to test the sealing of the connection between the bottle body 01 and the bottle cap 02. After the test is completed, the air column needs to be unplugged again and transferred to another device for sealing test of the connection between the rotating cover 03 and the bottle cap 02, and the test efficiency is low. Utility Model Content

[0003] In order to improve the inspection efficiency of bottles, the present application provides a bottle inspection tool.

[0004] The bottle inspection tool provided in this application adopts the following technical solution:

[0005] A bottle inspection tool, comprising a sealing cover, wherein a plurality of air nozzles are arranged in the sealing cover, wherein the air nozzles correspond one-to-one to the one-way air holes on the rotating cover, wherein a plurality of first air inlets are arranged on the sealing cover, wherein the first air inlets correspond one-to-one to the one-way air holes and are connected, and wherein the sealing cover is further provided with a second air inlet;

[0006] The sealing cover is used to cover the bottle cap so that the bottle cap and the sealing cover together enclose a sealed space, and at the same time the air nozzle is pressed into the corresponding one-way air hole, and the second air inlet is connected to the sealed space.

[0007] By adopting the above technical solution, when detecting the sealing performance at the connection between the bottle body and the bottle cap, and at the connection between the rotating cap and the bottle cap, simply tightly cover the sealing cap on the bottle cap, then externally connect the air inlet pipes to both the first air inlet and the second air inlet. First, close the air inlet pipe of the second air inlet, inject gas into the air inlet pipe of the first air inlet. The gas is injected into the bottle body through the first air inlet and the air nozzle in sequence. Observe the pressure sensor or the air flow detection device. When the set value is reached, stop injecting air and observe the pressure sensor or the air flow detection device. If the numerical change exceeds the detection range, it indicates that the sealing performance at the connection between the bottle body and the bottle cap is poor;

[0008] After the sealing performance detection at the connection between the bottle body and the bottle cap is completed, discharge the gas inside the bottle body through the first air inlet and the air nozzle to restore the internal air pressure of the bottle body to the initial value. Then, close the air inlet pipe connected to the first air inlet, open the air inlet pipe connected to the second air inlet and inject gas. The gas is injected into the sealed space formed by the bottle cap and the sealing cap through the second air inlet. Observe the pressure sensor or the air flow detection device. When the set value is reached, stop injecting air and observe the pressure sensor or the air flow detection device. If the numerical change exceeds the detection range, it indicates that the sealing performance at the connection between the bottle cap and the rotating cap is poor;

[0009] It should be noted that before this detection, the one-way air hole on the rotating cap has been separately detected for its sealing performance. Therefore, the one-way air hole will not affect the detection result of the sealing performance at the connection between the bottle cap and the rotating cap. Moreover, when injecting gas into the bottle body, even if there is leakage at the connection between the bottle cap and the rotating cap, the air pressure inside the bottle body and the air pressure inside the sealed space can still remain the same. If the air pressure value changes after stopping injecting air, the gas can only be determined to leak from the connection between the bottle body and the bottle cap. Therefore, the sealing performance at the connection between the bottle cap and the rotating cap will not affect the detection result of the sealing performance at the connection between the bottle body and the bottle cap;

[0010] In summary, this tooling does not require repeated artificial plugging and unplugging of the air column for airtightness detection, and can detect the sealing performance at the connection between the bottle body and the bottle cap, and at the connection between the rotating cap and the bottle cap on one device without transfer, which is beneficial to improving the detection efficiency of the bottle body.

[0012] Optionally, a pressing assembly is connected to the sealing cap, and the pressing assembly is used to press the sealing cap on the bottle cap.

[0013] By adopting the above technical solution, the pressing assembly facilitates quickly covering the sealing cap tightly on the bottle cap.

[0014] Optionally, the pressing assembly includes a mounting base, on which a guide sleeve is provided. A pressing rod is inserted through the guide sleeve, and the pressing rod is adapted to the guide sleeve. One end of the pressing rod is connected to the sealing cover, and the other end of the pressing rod is connected to a connecting plate by a hinge. One end of the connecting plate away from the pressing rod is hinged to a folding rod. The bent portion of the folding rod is hinged to the connecting plate. One end of the folding rod is hinged to the mounting base, and the other end of the folding rod is connected to a wrench.

[0015] By adopting the above technical solution, place the bottle body directly below the sealing cover, align the bottle cap with the sealing cover, and then pull the wrench to drive the connecting plate to move by the folding rod. The connecting plate drives the pressing rod to move, and the pressing rod moves vertically downward under the guiding action of the guide sleeve, so that the pressing rod drives the sealing cover to be tightly pressed on the bottle cap, which is convenient and fast.

[0016] Optionally, a fixing plate is connected to the end of the pressing rod away from the connecting plate, and the fixing plate is detachably connected to the sealing cover.

Detailed Embodiment

[0031] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 drawings.

[0032] The embodiment of the present application discloses a bottle body detection tooling.

[0033] As Figure 2 , the bottle body detection tooling includes a support frame 1, a sealing cover 3 and a pressing assembly 2;

[0034] The support frame 1 includes a vertical plate 11. Side plates 12 are bolted to both sides of the vertical plate 11. The bottom surface of the side plates 12 is flush with the bottom surface of the vertical plate 11. A bottom plate 13 is bolted between the two side plates 12. The bottom plate 13 is spliced with the vertical plate 11. Two limiting grooves 131 are formed in the bottom plate 13, and the limiting grooves 131 are adapted to the fixing parts 011 at the bottom of the bottle body 01. Four limiting plates 14 are bolted to the vertical plate 11. The side of the limiting plate 14 facing away from the vertical plate 11 can be attached to the peripheral surface of the bottle body 01. Two of the limiting plates 14 and one limiting groove 131 are in a group to jointly position one bottle body, and the other two limiting plates 14 and the other limiting groove 131 are in a group to jointly position another bottle body. A top plate 15 is bolted to the top of the vertical plate 11. The top plate 15 is located on the side of the vertical plate 11 facing away from the limiting plate 14. A reinforcing rib 16 is bolted below the top plate 15, and the reinforcing rib 16 is bolted to the vertical plate 11.

[0035] Two connecting seats 17 are bolted to the vertical plate 11. The number of the pressing components 2 is two. Both of the two pressing components 2 are installed on the top of the vertical plate 11 and are respectively installed on the two connecting seats 17. The two pressing components 2 are respectively located directly above the two limiting grooves 131;

[0036] The pressing component 2 includes a mounting seat 21. The mounting seat 21 is bolted to the connecting seat 17. A guide sleeve 22 is integrally formed on the mounting seat 21. The central axis of the guide sleeve 22 is perpendicular to the bottom plate 13. A folding rod 23 is hinged to one end of the mounting seat 21 away from the guide sleeve 22. A wrench 24 is connected to the folding rod 23. Connecting plates 25 are hinged to both sides of the bending part of the folding rod 23. A pressing rod 26 is hinged to each of the two connecting plates 25. The pressing rod 26 passes through the guide sleeve 22 and is adapted to the guide sleeve 22. A fixing plate 27 is fixed to the end of the pressing rod 26 away from the connecting plate 25. The sealing cover 3 is bolted to the fixing plate 27.

[0037] As Figure 3 and Figure 4 , a mounting plate 31 is installed in the sealing cover 3. Four air nozzles 32 are installed at the bottom of the mounting plate 31. The four air nozzles 32 correspond to the one-way air holes 031 of the rotating cover 03 one by one. Four first air inlets 33 are formed on the peripheral surface of the sealing cover 3. Four air channels 34 are formed in the sealing cover 3. The first air inlets 33 are in one-to-one correspondence and communication with the air channels 34. The air channels 34 are in one-to-one correspondence and communication with the air nozzles 32. A second air inlet 35 is also formed on the peripheral surface of the sealing cover 3. When the sealing cover 3 is properly placed on the bottle cap 02, the bottle cap 02 and the sealing cover 3 jointly enclose a sealed space. At the same time, the air nozzles 32 are pressed into the corresponding one-way air holes 031. The second air inlet 35 penetrates through the inner side wall and the outer side wall of the sealing cover 3, and the second air inlet 35 is in communication with the sealed space.

[0038] When conducting the airtightness detection at the connection between the bottle body 01 and the bottle cap 02, and at the connection between the rotary cap 03 and the bottle cap 02, first place the bottle body 01 on the bottom plate 13, so that the fixing part 011 below the bottle body 01 is completely located within the limit groove 131, and the circumferential surface of the bottle body 01 is in contact with the side surface of the limit plate 14. At this time, the bottle body is exactly below the sealing cap 3, and each one-way air hole 031 on the rotary cap 03 corresponds exactly to the air nozzle 32;

[0039] Then pull down the wrench 24 to drive the folding rod 23 to drive the connecting plate 25 to move. The connecting plate 25 drives the pressure rod 26 to move. The pressure rod 26 moves vertically downward under the guiding action of the guiding sleeve 22, so that the pressure rod 26 drives the sealing cap 3 to press tightly on the convex part of the bottle cap 02;

[0040] Then externally connect the air inlet pipes to both the first air inlet 33 and the second air inlet 35. First, close the air inlet pipe of the second air inlet 35, and inject gas into the air inlet pipe of the first air inlet 33. The gas is injected into the bottle body 01 through the first air inlet 33, the air passage 34 and the air nozzle 32 in sequence. Observe the pressure sensor or the air flow detection device. When the set value is reached, stop the air intake and observe the pressure sensor or the air flow detection device. If the numerical change exceeds the detection range, it means that the airtightness at the connection between the bottle body 01 and the bottle cap 02 is poor;

[0041] After the airtightness detection at the connection between the bottle body 01 and the bottle cap 02 is completed, discharge the gas inside the bottle body 01 through the first air inlet 33 and the air nozzle 32 to restore the internal air pressure of the bottle body 01 to the initial value. Then close the air inlet pipe connected to the first air inlet 33, open the air inlet pipe connected to the second air inlet 35 and inject gas. The gas is injected into the sealed space formed by the bottle cap 02 and the sealing cap 3 through the second air inlet 35. Observe the pressure sensor or the air flow detection device. When the set value is reached, stop the air intake and observe the pressure sensor or the air flow detection device. If the numerical change exceeds the detection range, it means that the airtightness at the connection between the bottle cap 02 and the rotary cap 03 is poor;

[0042] It should be noted that before conducting this detection, the one-way air holes 031 on the rotary cap 03 have been individually subjected to airtightness detection. Therefore, the one-way air holes 031 will not affect the detection result of the airtightness at the connection between the bottle cap 02 and the rotary cap 03. Moreover, when injecting gas into the bottle body 01, even if there is leakage at the connection between the bottle cap 02 and the rotary cap 03, the air pressure inside the bottle body 01 and the air pressure inside the sealed space can still remain the same. If the air pressure value changes after stopping the air intake, the gas can still only be determined to leak from the connection between the bottle body 01 and the bottle cap 02. Therefore, the sealing performance at the connection between the bottle cap 02 and the rotary cap 03 will not affect the detection result of the airtightness at the connection between the bottle body 01 and the bottle cap 02.

[0043] In summary, this tooling does not require repeated manual plugging and unplugging of air columns for airtightness detection, and can perform airtightness detection at the joints between the bottle body 01 and the bottle cap 02, and between the rotary cap 03 and the bottle cap 02 on one device without transfer, which is conducive to improving the detection efficiency of the bottle body.

[0044] The above are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
