Abstract
Description
Technical Field
[0001] This application relates to the field of bottle sealing test technology, and in particular to a gas detection mechanism for preventing tilting of a care solution bottle. Background Technology
[0002] Testing the seal of contact lens solution bottles is a crucial step in ensuring product quality and safety. Common testing methods include vacuum testing and pressure testing, with pressure testing being widely used due to its simplicity and low operating conditions. The pressure decay method involves filling the bottle with gas at a certain pressure and then monitoring whether the test pressure value is reached to determine the bottle's seal.
[0003] Currently used as Figure 1 The detection equipment shown mainly includes a conveyor belt for the bottle and a detection tube for filling the bottle with gas. When the bottle is conveyed to the bottom of the detection tube, the position sensor detects that the bottle is in position and stops. Then the detection tube moves down and is pressed against the bottle mouth by the cap at its end. Gas is then filled into the bottle, and the bottle's sealing performance is determined by the gas pressure value. However, contact lens solution bottles are usually made of blow-molded plastic. On some bottles, the upper end of the bottle mouth is not horizontal, resulting in air leakage after contact with the cap, affecting the detection results. Increasing the contact pressure between the cap and the bottle mouth to make them fit tightly will cause the bottle mouth to tilt due to the plastic molding of the bottle. This not only fails to solve the leakage problem but also damages the bottle, increasing the defect rate and production costs. Summary of the Invention
[0004] To address the aforementioned problems, this application aims to provide a gas detection mechanism for preventing the bottle from tilting during testing. By incorporating a rubber nozzle, a first clamping plate, and a second clamping plate, this application effectively reduces the pressure on the bottle nozzle while ensuring the bottle's airtightness during testing, thus solving the current problem of the bottle nozzle easily tilting during testing.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a gas detection mechanism for preventing tilting of a nursing solution bottle, comprising detection air tubes spaced apart, a conveyor belt disposed below the detection air tubes, the nursing solution bottle being conveyed on the conveyor belt, the nursing solution bottle comprising a bottle body and a bottle mouth, cap connecting ridges spaced apart on the outer wall of the bottle mouth, a rubber nozzle disposed at the lower end of the detection air tube, the rubber nozzle having a central hole communicating with the detection air tube, the outer wall of the rubber nozzle having a conical structure, the outer diameter of its top end being larger than the inner diameter of the bottle mouth, and the outer diameter of its bottom end being smaller than the inner diameter of the bottle mouth.
[0006] Preferably, a first cylinder is symmetrically arranged on both sides of the conveyor belt. A first clamping plate is horizontally arranged at the end of the piston rod of the first cylinder. A first arc groove is provided at the outer end of the first clamping plate. The first arc groove is offset downward from the connecting edge of the cover body on the lower side, and the first arc groove and the connecting edge of the cover body partially overlap horizontally.
[0007] Preferably, a second cylinder is symmetrically arranged on both sides of the conveyor belt. A second clamping plate is horizontally arranged at the end of the piston rod of the second cylinder. A second arc groove is provided at the outer end of the second clamping plate. The second arc groove is offset upward from the connecting edge of the cover on the upper side, and the second arc groove and the connecting edge of the cover partially overlap horizontally.
[0008] Preferably, a lifting plate is vertically provided at the tail end of the first cylinder and the second cylinder, and the vertical height of the first cylinder and the second cylinder is adjusted by the lifting plate.
[0009] The beneficial effects of this application are as follows: By setting a rubber nozzle at the lower end of the testing tube, which makes circumferential contact with the inner wall of the bottle mouth, the soft material of the rubber nozzle, compared to the metal material of the cap, can resist the downward contact of the rubber nozzle, thus preventing the bottle mouth from deforming and tilting. This achieves a seal between the rubber nozzle and the bottle mouth, solving the problem of air leakage during the process of filling gas through the testing tube, and avoiding the problem of excessive downward pressure causing the bottle mouth to tilt, effectively improving the smooth progress of the bottle sealing test.
[0010] By setting the first and second clamping plates, the bottle mouth can be moved upward to contact the rubber nozzle during testing to achieve a seal, avoiding the problem of tilting the bottle mouth due to downward pressure; and after testing, the bottle mouth can be tilted downward to detach from the rubber nozzle, thereby improving the sealing performance during testing without increasing the pressure on the bottle mouth.

Detailed Implementation
[0023] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.
[0024] See attached document Figures 3-11 The illustrated gas detection mechanism for preventing tilting of a nursing solution bottle includes detection gas tubes 1 spaced apart. A conveyor belt 2 is positioned below the detection gas tubes 1, on which the nursing solution bottle is conveyed. Each nursing solution bottle includes a bottle body 31 and a bottle nozzle 32. Connecting ridges 321 are spaced apart on the outer wall of the bottle nozzle 32, which are connected and sealed to a bottle cap (the bottle cap has matching connecting ridges inside, which are locked together by external pressure). To address the current problem of air leakage at the bottle nozzle 32, causing it to tilt, a mechanism is designed to... Figure 3 As shown, this application provides a rubber nozzle 4 at the lower end of the detection air tube 1. The rubber nozzle 4 has a central hole (not shown in the figure) that communicates with the detection air tube 1. The outer wall of the rubber nozzle 4 is conical, with its top outer diameter larger than the inner diameter of the bottle mouth 32 and its bottom outer diameter smaller than the inner diameter of the bottle mouth 32. During detection, if... Figure 3As shown, when the bottle body 31 reaches below the detection air tube 1, the air tube moves downward, driving the rubber nozzle 4 into the bottle mouth 32. Since the rubber nozzle 4 is made of soft material, after it enters the bottle mouth 32, it can further contact the inner wall of the bottle mouth 32 port through the downward pressure of the detection air tube 1. The bottle body 31, due to the soft material of the rubber nozzle 4, can resist the downward contact of the rubber nozzle 4 compared to the metal material of the cap, so that the bottle mouth 32 does not deform and tilt. Thus, the rubber nozzle 4 achieves a seal with the bottle mouth 32 port. During the process of filling gas through the detection air tube 1, the problem of air leakage is solved, and the problem of the bottle mouth 32 tilting due to excessive downward pressure is avoided, effectively improving the smooth progress of the bottle body 31 sealing test.
[0025] To further reduce the downward pressure of the rubber nozzle 4 on the bottle nozzle 32, which causes the bottle nozzle 32 to tilt, such as... Figure 5-8 As shown, first cylinders 51 are symmetrically arranged on both sides of the conveyor belt 2. A first clamping plate 52 is horizontally arranged at the end of the piston rod of the first cylinder 51. A first arcuate groove 5a is provided at the outer end of the first clamping plate 52. The first arcuate groove 5a is offset downwards from the connecting edge 321 of the cover body on the lower side, and the first arcuate groove 5a and the connecting edge of the cover body partially overlap horizontally. During detection, if... Figure 8 As shown, the detection tube 1 first drives the detection nozzle to move down into the bottle mouth 32 and connect with the inner wall of the bottle mouth 32. At this time, the rubber nozzle 4 does not press down on the bottle mouth 32 (the height of the bottle body 31 is fixed, so the downward movement height of the detection tube 1 and the detection nozzle can also be precisely controlled, so that the rubber nozzle 4 connects with the inner wall of the bottle mouth 32 after moving down). Then, the first cylinder 51 drives the first clamping plate 52 to move towards the bottle mouth 32. Because the first clamping plate 52 and the lower cover connecting edge 321 are misaligned vertically and have... With a certain degree of overlap, when the first arc groove 5a contacts the cap connecting edge 321, the first arc groove 5a is offset downwards. Therefore, the first arc groove 5a can drive the bottle mouth 32 and the bottle body 31 to move upward as a whole through the cap connecting edge 321. This allows the bottle mouth 32 to move upwards and actively press against the outer wall of the rubber nozzle 4 to seal, thereby further reducing the downward pressure of the rubber nozzle 4 on the bottle mouth 32. On the basis of achieving a sealed contact, this avoids the problem of the bottle mouth 32 tilting due to the downward pressure on the bottle mouth 32.
[0026] To achieve the separation of the nozzle 32 from the rubber valve 4 after the above tests are completed, as follows: Figure 9-10As shown, second cylinders 61 are symmetrically arranged on both sides of the conveyor belt 2. A second clamping plate 62 is horizontally arranged at the end of the piston rod of the second cylinder 61. A second arc groove (not shown in the figure) is provided at the outer end of the second clamping plate 62. The second arc groove is offset upward from the upper cap connecting edge 321, and the second arc groove and the cap connecting edge partially overlap horizontally. The second clamping plate 62 has the same function as the first clamping plate 52 but in the opposite direction. After the test is completed, the first clamping plate 52 first disengages from the bottle mouth 32 and resets. At the same time, the second clamping plate 62 extends and presses down on the bottle mouth 32 from the upper cap connecting edge 321, so that the bottle mouth 32 is smoothly separated from the rubber nozzle 4 and is received by the conveyor belt 2. Then the conveyor belt 2 transports forward to perform the same test on the next bottle 31.
[0027] To accommodate the testing of bottles 31 of different heights, such as Figure 11 As shown, a lifting plate 7 is vertically arranged at the tail end of the first cylinder 51 and the second cylinder 61, and the vertical height of the first cylinder 51 and the second cylinder 61 is adjusted by the lifting plate 7. The specific structure is as follows... Figure 11 As shown, preferably, a vertically oriented slot 7a is provided on the lifting plate 7. A bolt 8 passes through the slot 7a to connect the tail ends of the first cylinder 51 and the second cylinder 61. The bolt 8 moves vertically within the slot 7a, allowing adjustment of the height of the first cylinder 51 and the second cylinder 61, so that the first clamping plate 52 and the second clamping plate 62 correspond to different heights at the cover connecting ridge 321. After adjustment, tightening the bolt 8 locks the height of the first cylinder 51 and the second cylinder 61.
[0028] The principle of this application is as follows: When performing a sealing test on the bottle body 31, the conveyor belt 2 transports the bottle body 31 to a position vertically aligned with the detection air pipe 1. Then, the detection air pipe 1 drives the detection nozzle downwards into the bottle mouth 32 and contacts the inner wall of the bottle mouth 32. Subsequently, the first cylinder 51 drives the first clamping plate 52 to move towards the bottle mouth 32. When the first arc groove 5a contacts the cap connecting edge 321, the first arc groove 5a allows air to pass through the cap connecting edge 321. 1. Drive the bottle nozzle 32 and bottle body 31 to move upward as a whole, thereby achieving active sealing between the bottle nozzle 32 and the outer wall of the rubber nozzle 4 after the bottle nozzle 32 moves upward. Then, the detection tube 1 inflates the bottle body 31 to perform pressure detection. After the first clamping plate 52 is reset, the second clamping plate 62 extends to drive the upper cap connecting rib 321 to move downward, so that the bottle nozzle 32 is separated from the rubber nozzle 4, and the bottle body 31 is supported on the conveyor belt 2. The conveyor belt 2 moves forward to perform the detection of the next bottle body 31.

Various changes and modifications may be made to this utility model without departing from its spirit and scope of protection, and all such changes and modifications fall within the scope of protection claimed by this utility model.
