Description

[0002] Spring water usually refers to groundwater that flows naturally from mountainous areas. It is often considered to be purer and healthier than tap water in urban water supply systems. Because spring water is filtered through multiple layers of rocks and soil underground and is rich in minerals, such as calcium, magnesium and other elements that are beneficial to the human body, it is necessary to use packaging bottles to store spring water during production. The mouth of the packaging bottle plays an important role. When the mouth of the bottle leaks, the spring water in the bottle will be polluted and deteriorate. Therefore, the sealing test of the mouth of the packaging bottle is particularly critical.

[0038] When the enclosed space is sealed, the inflatable component 7 is inflated and pressurized to a certain pressure value, and the telescopic component 3 drives the sealing component 4 to slide in the bottle mouth.

During the test, start the adjustment mechanism 2 to force the telescopic component 3 to move down, and the telescopic component 3 drives the sealing component 4 to move to a reasonable position, that is, the starting height, and start the air supply component 6 at the same time. The air supply component 6 inflates the expansion component 5 so that the expansion component 5 and the bottle mouth are closely fitted to form a sealed environment.

[0048] like Figure 1 , Figure 2 , Fig. 9 and Fig.10 As shown, a device for detecting the sealing property of a bottle mouth of a packaging bottle for producing spring water of the present invention, the pushing component 9 includes a cylinder body 901 arranged on a pressure plate 1, an air guide hose 902 connected to the cylinder 301 is arranged on the cylinder body 901, a pushing plug 903 matched with the cylinder body 901 is arranged in the cylinder body 901, a pushing rod 904 penetrating the cylinder body 901 is arranged on the pushing plug 903, and the detecting component 10 is connected to the pushing rod 904.

[0049] like Figure 1 , Figure 2 , Fig. 9 and Fig.10 As shown, a device for detecting the sealing property of the bottle mouth of a packaging bottle for producing spring water of the present invention, the detection component 10 includes a support plate 1001 arranged on a pressure plate 1, a shaft 1002 is connected to a bearing on the support plate 1001, a detection gear 1003 is fixedly sleeved on the shaft 1002, a detection spur rack 1004 meshing with the detection gear 1003 is arranged on the push rod 904, a disk 1005 is fixedly sleeved on the shaft 1002, a pointer 1006 is arranged on the disk 1005, and an indicator disk 1007 matched with the pointer 1006 is installed on the pressure plate 1.

[0050] Working principle: When testing the sealing property of the bottle mouth, the slide bar 202, the sealing plug 402 and the telescopic assembly 3 are inserted into the bottle mouth, and the bottle is clamped by the device, and sufficient pressure is applied to the mouth-pressing plate 1, so that the mouth-pressing plate 1 is in close contact with the bottle mouth to form a seal. During the test, the motor 204 is started, and the output shaft of the motor 204 rotates to drive the adjusting gear 205 to rotate. Under the action of the supporting outer cylinder 201, the adjusting spur rack 203 is forced to move downward, so that the slide bar 202 slides downward in the supporting outer cylinder 201;

[0051] Since the sealing plug 402 is not in close contact with the bottle mouth, when the slide bar 202 moves downward, the spring 304 does not move, and the slide bar 202 drives the cylinder 301 and the force rod 303 to move, so that the force rod 303 drives the connecting plate 401 and the sealing plug 402 to move to the designated detection position, and the bottle mouth can be firstly inspected as a whole to determine whether the bottle mouth is leaking, and then the bottle mouth can be inspected in sections;

[0052] Close the second solenoid valve 702, open the first solenoid valve 503, start the air pump 601, and introduce the gas into the ventilation hose 501 through the air supply pipe 602 and the connecting pipe 603, and introduce the gas into the expansion airbag 504 through the ventilation hard pipe 502, so that the expansion airbag 504 expands and contacts closely with the bottle mouth to form a seal. At this time, the bottle mouth, the pressure plate, the sealing plug 402 and the expansion airbag 504 form a closed space;

[0053] Open the second solenoid valve 702, close the first solenoid valve 503, start the air pump 601, introduce the gas into the air filling pipe 701 through the air supply pipe 602 and the connecting pipe 603, introduce the gas into the closed space through the air supply pipe 602, inflate and pressurize the closed space, at this time the pressure in the closed space gradually increases, and use the pressure detection gauge 802 to detect the pressure in the closed space;

[0054] When the pressure detection gauge 802 detects that the pressure in the enclosed space reaches a preset value, due to the good sealing performance, the gas pressure increases, causing the gas pressure to act on the sealing plug 402, causing the edges of the sealing plug 402 and the expansion airbag 504 to slide downward along the bottle mouth, so that the sealing plug 402 drives the connecting plate 401 to move, and the connecting plate 401 drives the force-bearing rod 303 to slide downward, and the force-bearing plate drives the piston 302 to slide in the cylinder 301, and the spring 304 is stretched, so that the volume in the cylinder 301 increases and the pressure decreases, and the air guide hose 902 is used to operate. The gas in the cylinder body 901 enters the cylinder 301, forcing the push plug 903 to drive the push rod 904 to retreat, so that the push rod 904 drives the detection spur rack 1004 to retreat, and the detection spur rack 1004 drives the detection gear 1003 to rotate, forcing the shaft rod 1002 to rotate, the shaft rod 1002 drives the disk 1005 to rotate, and the disk 1005 drives the pointer 1006 to rotate an angle to point to a certain scale position on the indicator disk 1007. By comparing the pressure value of the scale disk with the pressure detection gauge 802, it is proved that the sealing of the bottle mouth is good.

[0055] When the pressure detection gauge 802 detects that the pressure value in the enclosed space does not change, the air pressure in the enclosed space cannot rise, which proves that the sealing of the bottle mouth is poor and there may be air leakage;

[0056] When the pressure detection gauge 802 detects that the pressure value in the enclosed space changes, but cannot reach the preset value, at this time, the edge of the sealing plug 402 and the expansion airbag 504 still slides downward along the bottle mouth, so that the sealing plug 402 drives the connecting plate 401 to move, and the connecting plate 401 drives the force-bearing rod 303 to slide downward, and the force-bearing plate drives the piston 302 to slide in the cylinder 301, and the spring 304 stretches, so that the volume in the cylinder 301 increases and the pressure decreases, and the gas in the cylinder body 901 enters the cylinder 301 through the action of the air guide hose 902. 01, forcing the push plug 903 to drive the push rod 904 to retreat, so that the push rod 904 drives the detection spur rack 1004 to retreat, and the detection spur rack 1004 drives the detection gear 1003 to rotate, forcing the shaft 1002 to rotate, the shaft 1002 drives the disk 1005 to rotate, and the disk 1005 drives the pointer 1006 to rotate an angle, pointing to a certain scale position on the indicator disk 1007. By comparing the pressure value of the dial with the pressure detection gauge 802, it is impossible to judge the air tightness of the bottle mouth at this time, and the gas in the inflation airbag 504 may be insufficient;

[0057] The air pump 601 is started again to continue to fill the gas into the expansion bag 504, so that the expansion bag 504 expands to a reasonable degree, which is conducive to correcting the expansion degree of the expansion bag 504 and improving the detection accuracy. The bottle mouth is tested again until the pressure in the enclosed space reaches the set value, and the tightness of the bottle mouth is judged to complete the overall detection of the bottle mouth. When the sealing of the bottle mouth is good, the sealing test of the bottle mouth is completed. When the sealing of the bottle mouth is poor, it is proved that there is a leak in the bottle mouth;

[0058] Start the pressure relief valve 804 to release the gas in the enclosed space, start the motor 204, and the output shaft of the motor 204 rotates to drive the adjusting gear 205 to rotate. Under the action of the supporting outer cylinder 201, the adjusting spur rack 203 is forced to move upward to the position close to the pressure plate 1, so that the slide bar 202 slides upward in the supporting outer cylinder 201, and starts the segmented detection from the starting position. Repeat the above steps. After each small section is detected, the slide bar 202 is moved downward for a distance, and the operation is cyclically performed to complete the detection of all sections of the bottle mouth and determine which section the gas leakage point is located.

[0059] The setting of the adjustment component can adjust the position of the telescopic component 3 and the sealing component 4, so that the sealing component 4 moves up and down, thereby completing the overall sealing and segmented sealing effect of the bottle mouth. At the same time, the clamping connection between the adjustment gear 205 and the adjustment spur rack 203 can limit the position of the telescopic component 3 and the sealing component 4, thereby improving the stability of the device; the setting of the telescopic component 3 can force the force-bearing rod 303 to move after the pressure in the sealed space is sufficient, which can not only prove that the sealing of the bottle mouth is good, but also effectively protect the bottle mouth, avoid the bottle mouth from bursting, and improve the protection effect of the device on the bottle mouth; the setting of the sealing component 4 can make the expansion component 5 located at different positions, and can adjust the expansion gas The airbag 504 is clamped, so that the sealing plug 402 and the expansion airbag 504 move synchronously, so that the bottle mouth, the sealing plug 402, the expansion airbag 504 and the pressure plate 1 form a closed space, which improves the sealing performance of the device and is conducive to the detection of the sealing performance of the bottle mouth; the setting of the air supply component 6 can provide gas, so that the expansion airbag 504 expands and contacts closely with the inner wall of the bottle mouth, and at the same time can inflate the closed space to increase the pressure in the closed space; the setting of the expansion component 5 can be combined with the sealing plug 402 to improve the sealing performance in the sealed space, and at the same time, the expansion airbag 504 is expanded, so that the device can detect bottle mouths of different sizes with little difference without replacement The device can be adapted to different bottle mouths without replacing sealing seats of different specifications, thereby improving the adaptability and compatibility of the device. The setting of the solenoid valve 503 can control the on-off of the gas; the setting of the inflation component 7 can introduce the gas into the enclosed space, so that the pressure in the enclosed space increases until the pressure reaches a preset value, which is beneficial to the pressure detection of the enclosed space by the pressure measuring component 8, and is beneficial to the sealing detection of the enclosed space; the setting of the pressure measuring component 8 can detect the air pressure in the enclosed space, and combine the sliding state of the sealing plug 402 and the expansion airbag 504 to judge the sealing of the enclosed space and the pressure of the expansion airbag 504, which is beneficial to the enclosed space. The push assembly 9 is set to transmit the movement of the piston 302 in the cylinder 301, and transmit the force to the push rod 904, so as to achieve a transmission effect, so that the push rod 904 drives the detection assembly 10 to move, and the detection assembly 10 is combined with the pressure measuring assembly 8 to judge and analyze the sealing performance, thereby improving the accuracy of the bottle mouth detection; the detection assembly 10 is set to realize an intuitive judgment of the movement of the sealing plug 402 and the expansion airbag 504, that is, when the sealing plug 402 and the expansion airbag 504 move, the pointer 1006 will deflect, and combined with the pressure measuring assembly 8, the sealing performance of the bottle mouth can be judged more accurately, the judgment speed is improved, and the efficiency of the bottle mouth detection is improved.

[0060] This solution can adapt to the detection of bottle mouths of different sizes, so that the device can be adapted to different bottle mouths, without the need to replace sealing seats of different specifications, thereby improving the compatibility of the device. At the same time, the bottle mouth can be detected as a whole and in sections, and the leakage point of the bottle mouth can be determined. The detection operation is simple, which is conducive to the detection of the bottle mouth, improves the detection efficiency of the bottle mouth, and reduces the detection cost of the enterprise; when the device is sealed in a confined space, it can quickly and intuitively judge the sealing of the bottle mouth. When the pressure detection gauge 802 detects that the pressure in the confined space reaches a preset value, the pointer 1006 deflects, proving that the sealing of the bottle mouth is good; when the pressure detection gauge 802 detects that the pressure value in the confined space does not change, the pointer 1006 does not deflect, proving that the sealing of the bottle mouth is poor; when the pressure detection gauge 802 detects that the pressure value in the confined space changes, but cannot reach the preset value, the pointer 1006 deflects slightly. At this time, it is necessary to adjust the expansion degree of the expansion airbag 504 and then judge the sealing of the bottle mouth again.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
