[0002] The airtightness detection of eye drop bottles aims to verify whether they can effectively prevent the intrusion of external air, moisture, microorganisms and other pollutants during production, transportation and storage, and at the same time keep the active ingredients of the drugs in the bottles stable.

[0003] After retrieval, the patent with the application number CN202321997292.1 discloses a sealing detection device for eye drop bottle production. The sealing detection device includes: a sealing component, which is installed above the liquid storage component; wherein, the sealing component includes a sealing box, the sealing box is provided with a clamping groove on one side of the liquid storage component, a jet nozzle is arranged inside the clamping groove, and an airbag is embedded on one side of the jet nozzle in the clamping groove. It relates to the technical field of drug bottle airtightness detection devices. Among them, a sealing component is provided. The bottom end of the sealing component is concave with a clamping groove, a jet nozzle is connected inside the clamping groove, and the air inlet of the jet nozzle is connected to a first air pump on one side of the sealing component. An airbag is arranged around the jet nozzle. When detecting the airtightness of the bottle mouths of eye drop bottles with different sizes, the airbag is inflated, and the inflated airbag covers the bottle mouths of the eye drop bottles to achieve a sealing effect. When detecting the sealing performance of eye drop bottles with different sizes, it is not necessary to replace the corresponding jet nozzles, which improves the detection efficiency.

[0004] When the above-mentioned scheme detects the airtightness of eye drop bottles, it detects them one by one, and through the manual feeding and discharging method, one eye drop bottle is taken and placed in the device for each detection. The degree of automation is low, and the detection process is also relatively cumbersome, which greatly reduces the efficiency of the airtightness detection of eye drop bottles. Therefore, we need to propose a sealing detection device for eye drop bottle production. Content of the Utility Model

This detection method is simple to operate, the detection result is easy to observe, and continuous detection is realized through the circular chain conveyor, improving the detection efficiency, so as to solve the problems put forward in the above background technique.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution: an eye drop bottle production sealing detection device, including a workbench 1, on which an annular chain conveyor 2 is installed. The annular chain conveyor 2 is used for intermittently conveying eye drop bottles. Through the setting of the annular chain conveyor 2, continuous feeding of eye drop bottles can be realized, and the eye drop bottles can be automatically conveyed to the detection position, thereby improving the efficiency of the sealing detection of eye drop bottles.

[0021] A plurality of limiting mechanisms 3 for placing eye drop bottles are equidistantly installed on the annular chain conveyor 2. The limiting mechanism 3 includes a bottom plate 31, two fixing plates 33 installed on the bottom plate 31, and two movable plates 36 for squeezing the eye drop bottles; the two fixing plates 33 and the two movable plates 36 are arranged alternately, that is, the two fixing plates 33 and the two movable plates 36 enclose a square frame, and the eye drop bottles can be limited by placing them inside the frame.

[0022] It should be noted that, in order to facilitate the smooth and quick placement of the eye drop bottles into the frame, inclined surfaces are provided at the upper ends of the sides of the fixing plate 33 and the movable plate 36.

[0023] A detection mechanism 4 is also installed on the workbench 1. The detection mechanism 4 includes two sealing covers 47 that can cover the bottom plate 31 and can be lifted. A pressure gauge 410 is installed on the top of the sealing cover 47, and cylinders 49 for pushing the movable plate 36 to move are installed on both sides of the sealing cover 47.

[0024] The barometer 410 is used to detect the air pressure inside the seal cover 47.

[0025] An annular seal groove 32 is formed on the upper surface of the bottom plate 31. An annular sealing ring 48 is connected to the bottom of the seal cover 47. The sealing ring 48 is engaged inside the seal groove 32. After the eye drop bottle is covered inside the seal cover 47, through the cooperation of the sealing ring 48 and the seal groove 32, the sealing performance between the seal cover 47 and the bottom plate 31 is achieved, which can ensure the stability of the air pressure inside the seal cover 47.

[0026] Both ends of the fixed plate 33 are connected with limit posts 34. Both ends of the movable plate 36 are provided with limit holes 37 for the limit posts 34 to pass through. A spring 35 sleeved around the limit post 34 is connected between the fixed plate 33 and the movable plate 36.

[0027] When the cylinder 49 pushes the movable plate 36 to move, the limit post 34 moves inside the limit hole 37, and the movable plate 36 squeezes the spring 35 to make it contract. The two movable plates 36 squeeze the eye drop bottle. If the eye drop bottle is airtight, the value of the barometer 410 remains unchanged. If the eye drop bottle is leaky, the gas in the eye drop bottle leaks into the seal cover 47, and the air pressure inside the seal cover 47 increases, then the value of the barometer 410 increases.

[0028] The detection mechanism 4 further includes a hollow support column 41 fixed on the workbench 1. A motor 43 is installed at the top of the hollow support column 41. One end of the output shaft of the motor 43 is connected with a lead screw 44.

[0029] A first connecting plate 45 is threadedly connected to the outer wall of the lead screw 44. Both ends of the first connecting plate 45 are connected with second connecting plates 46.

[0030] One end of the second connecting plate 46 is connected to the seal cover 47. A through hole 42 for the second connecting plate 46 to pass through and move is formed on the side of the hollow support column 41.

[0031] The motor 43 drives the lead screw 44 to rotate. The rotation of the lead screw 44 drives the first connecting plate 45 to move downward. The first connecting plate 45 drives the seal cover 47 to move downward through the second connecting plate 46, so that the seal cover 47 covers the bottom plate 31.

[0032] During use, the eye drop bottle is placed on the bottom plate 31 in the limiting mechanism 3. The eye drop bottle is located between the two fixed plates 33 and the two movable plates 36, and the side of the eye drop bottle is in contact with the fixed plates 33 and the movable plates 36. Then the annular chain conveyor 2 drives the limiting mechanism 3 and the eye drop bottle to move. When the eye drop bottle moves below the seal cover 47 in the detection mechanism 4;

[0033] The motor 43 drives the lead screw 44 to rotate. The rotation of the lead screw 44 drives the first connecting plate 45 to move downward. The first connecting plate 45 drives the sealing cover 47 to move downward through the second connecting plate 46, so that the sealing cover 47 covers the bottom plate 31, and the sealing ring 48 at the bottom of the sealing cover 47 is engaged inside the sealing groove 32 to ensure the airtightness of the internal space of the sealing cover 47.

[0034] Then, the air cylinder 49 is operated. The piston rod of the air cylinder 49 extends and contacts the movable plate 36, pushing the two movable plates 36 to move towards each other. The movable plates 36 squeeze the eye drops bottle. If the eye drops bottle is airtight, the value of the pressure gauge 410 remains unchanged. If the eye drops bottle is air-leaking, the value of the pressure gauge 410 becomes larger.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
