[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 6 As shown, this utility model provides a sealing detection device for medical medicine bottles, including a detection box 1, a water storage cavity at the bottom of the detection box 1, and an airtightness detection element on the detection box 1.

[0025] The inspection box 1 is arranged with a loading station, a motion station, an inspection station and an unloading station in a clockwise direction. The position of the inspection station corresponds to the position of the airtightness detection element.

[0026] Both the loading and unloading stations are located above the water storage chamber;

[0027] The airtightness detection element includes a transparent observation window 14 set on the test box 1 and cooperating with the water storage chamber, and a visual inspection probe 15 set on the test box 1 facing the transparent observation window 14.

[0028] By setting up the visual inspection probe 15, it is possible to quickly detect whether the medical bottle in the water storage chamber produces air bubbles and whether the airtightness of the medical bottle to be tested is up to standard.

[0029] A microcontroller 16 is installed on the inspection box 1. A negative pressure pump 17 is installed on the inspection box 1. The negative pressure port of the negative pressure pump 17 is connected to the water storage chamber through a negative pressure pipe. A pressure probe 24 is installed on the negative pressure pipe. The data terminals of the pressure probe 24 and the visual inspection probe 15 are both connected to the microcontroller 16.

[0030] During the testing process, the negative pressure pump 17 is used to maintain the water storage chamber between the two sealed partitions 5 at a set negative pressure. By maintaining the negative pressure, the leakage of the medical medicine bottle becomes obvious.

[0031] Furthermore, during testing, the negative pressure suction in the negative pressure pipe can only slightly adsorb the water in the water storage chamber between the two sealing partitions 5, and the adsorbed water is insufficient to enter the interior of the negative pressure pump 17.

[0032] A stepper frame 2 is rotatably mounted on the inspection box 1. An active gear ring 3 is rotatably sleeved on the stepper frame 2. A motor 4 is mounted on the inspection box 1. Both the stepper frame 2 and the active gear ring 3 are driven by the motor 4.

[0033] It also includes a synchronous shaft 10 rotatably connected to the inspection box 1. The output shaft end of the motor 4 is connected to the synchronous shaft 10 via a belt. A linkage gear 11 is installed on both the synchronous shaft 10 and the drive gear ring 3. The two linkage gears 11 mesh with each other.

[0034] A missing gear 12 is mounted on the synchronous shaft 10. The missing gear 12 has a transmission tooth surface with a full arc of 90°. A stepper gear 13 is mounted on the stepper frame 2. The transmission tooth surface is evenly distributed with teeth that mate with the stepper gear 13.

[0035] By setting the stepper gear 13 and the missing gear 12, the stepper rotating frame 2 can rotate 90° periodically at a set interval, and the stepper rotating frame can rotate step by step. During the non-rotation cycle of the stepper rotating frame 2, the movement of the medical bottle and the airtightness detection operation are then performed.

[0036] A set of sealing partitions 5 arranged in a circular array are installed on the stepping frame 2. Detection components are set on the stepping frame 2 and at the positions corresponding to each pair of sealing partitions 5. A set of intermediate gears 6 are rotatably installed on the inspection box 1 at the position corresponding to the water storage chamber. The intermediate gears 6 are connected to the drive gear ring 3 for transmission.

[0037] The intermediate gear 6 is positioned between the inspection station and the loading station;

[0038] The detection component includes a reciprocating drive module and a guide frame 7 fixedly connected to the stepping frame 2. The reciprocating drive module is connected to a reciprocating frame 8, which can be driven by an intermediate gear 6 and moves back and forth within the guide frame 7. A rotatable detection screen cylinder 9 is rotatably connected to the inner wall of the reciprocating frame 8.

[0039] The reciprocating drive module includes a rotatable I-shaped wheel 18 mounted on the reciprocating frame 8 and a gear shaft 19 rotatably mounted on the stepping frame 2. An external gear 20 is mounted on the gear shaft 19 and is adapted to and connected to the intermediate gear 6. An eccentric protrusion 21 is mounted on the gear shaft 19 and is adapted to and connected to the I-shaped wheel 18. A differential gear 22 is mounted on both the I-shaped wheel 18 and the detection screen cylinder 9. The two differential gears 22 mesh with each other. A set of return springs 23 is installed between the reciprocating frame 8 and the guide frame 7.

[0040] The detection mesh cylinder 9 has a set of holes arranged in a circular array. The detection mesh cylinder 9 is a hollow cylindrical structure with one end open.

[0041] When the medical bottle is placed on the detection mesh cylinder 9, and the detection mesh cylinder 9 carrying the medical bottle rotates between the loading station and the detection station, due to the setting of the intermediate gear 6, on the one hand, the reciprocating frame 8 can drive the medical bottle to reciprocate, and on the other hand, the medical bottle can rotate at a set speed. Through the reciprocating motion and rotation of the medical bottle, the loose cap and bottle body in the medical bottle can be fully separated, and the looseness between the cap and the bottle body is further amplified. By amplifying the looseness of the medical bottle, the false negative rate of this detection device is effectively reduced and the airtight leak point of the medical bottle is amplified to improve the detection efficiency.

[0042] When the detection screen cylinder 9 is in the unloading station, detection station, and loading station, it remains stationary due to the absence of the intermediate gear 6. After the detection screen cylinder 9 remains stationary, the water in the water storage chamber in the detection station is kept still by the setting of the sealing partition 5.

[0043] Working principle and usage process of this utility model:

[0044] When the medical bottle is placed on the detection mesh cylinder 9, and the detection mesh cylinder 9 carrying the medical bottle rotates between the loading station and the detection station, the intermediate gear 6 enables the reciprocating frame 8 to drive the medical bottle to reciprocate, and also enables the medical bottle to rotate at a set speed. Through the reciprocating motion and rotation of the medical bottle, the loose cap and bottle body are fully separated, further amplifying the looseness between the cap and the bottle body. The magnification of the detection device effectively reduces the false detection rate and amplifies the airtight leaks of the medical bottles to improve detection efficiency. When the detection mesh cylinder 9 is in the unloading and loading positions, the detection mesh cylinder 9 remains stationary due to the absence of the intermediate gear 6, which facilitates the loading of medical bottles in the loading position and the unloading of medical bottles in the unloading position. By setting the visual detection probe 15, it detects whether the medical bottles in the water storage chamber produce air bubbles. When air bubbles are produced, the medical bottles are judged to be unqualified, otherwise they are qualified.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
