Description

Technical Field

[0001] This utility model relates to the technical field of pressure resistance testing equipment for packaging bottles, and in particular to a pressure testing device for pharmaceutical liquid packaging bottles. Background Technology

[0002] During logistics, packaging bottles are subjected to external forces such as stacking pressure and vibration. Through pressure resistance tests, such as vertical load test and constant pressure test, the structural strength can be verified, the pressure bearing limit of the bottle can be assessed, and deformation or breakage due to squeezing can be avoided.

[0003] In fact, before modern liquid medicines are bottled, each empty bottle needs to be pressure tested before filling. However, existing pressure testing devices for liquid medicine packaging bottles generally have the problem of inaccurate bottle positioning when testing the pressure resistance of the bottle body. This may lead to a reduction in the sealing between the filling port and the bottle mouth, resulting in gas leakage during the testing process, and consequently, inaccurate pressure test data.

[0004] In view of this, a pressure detection device for pharmaceutical liquid packaging bottles is proposed to solve the above problems. Utility Model Content

[0005] To address the technical problem of inaccurate data from pressure testing devices for pharmaceutical liquid packaging bottles, this utility model provides a pressure testing device for pharmaceutical liquid packaging bottles.

[0006] This utility model is achieved using the following technical solution: a pressure testing device for pharmaceutical liquid packaging bottles, including a support, a limiting platform fixedly connected to one side of the support, multiple sliding rods slidably connected to the limiting platform, the multiple sliding rods being arranged in a circumferential array, a push ring fixedly connected to the lower end of the multiple sliding rods, the push ring having multiple push grooves, multiple bow-shaped swing plates rotatably connected to the lower side of the limiting platform, a clamping block fixedly connected to the lower end of each bow-shaped swing plate, the multiple bow-shaped swing plates and the multiple push grooves being respectively paired, the outer side of each bow-shaped swing plate being slidably connected to the inner side of the corresponding push groove, a clamping drive mechanism for bringing the multiple clamping blocks closer or further apart being provided on the upper side of the limiting platform, and a pressure resistance testing mechanism being provided on the side of the limiting platform.

[0007] As a further improvement to the above solution, the clamping drive mechanism includes a cylinder fixedly connected to the upper side of the limiting platform. The piston rod of the cylinder passes downward through the limiting platform and is fixedly connected to a three-way pipe. A bottle mouth adapter mechanism is provided at the lower end of the three-way pipe.

[0008] Through the above technical solution, the cylinder can push the adapter cap downwards and onto the bottle cap to inflate it, thereby achieving the function of controlling air pressure.

[0009] As a further improvement to the above solution, the bottle neck adapter mechanism includes an adapter cap that communicates with the lower end of the three-way tube. A sealing ring is installed on the inner side of the adapter cap, and a slot is opened on the outer side of the adapter cap, which engages with the push ring.

[0010] As a further improvement to the above solution, a pressure sensor is installed on one side of the three-way pipe.

[0011] With the above technical solution, when the high-pressure air pump pumps air into the bottle, the air pressure inside the bottle gradually increases. At this time, the pressure sensor can still detect the air pressure inside the bottle. When the air pressure reaches the qualified standard value and the bottle does not break, it proves that the pressure resistance performance of the bottle meets the quality standard. Otherwise, the pressure resistance quality of the bottle is unqualified.

[0012] As a further improvement to the above solution, the pressure resistance testing mechanism includes a high-pressure air pump fixedly connected to one side of the limiting platform, and a flexible hose is connected between the lower side of the high-pressure air pump and the three-way pipe.

[0013] The high-pressure air pump can be used to inflate the drug liquid packaging bottle through the hose and then through the adapter cap. Since the adapter cap needs to be pushed up or down by the cylinder at the beginning or after the test, the hose can deform itself to match the height change of the adapter cap.

[0014] As a further improvement to the above solution, an LED industrial control panel is installed on the side of the limiting platform away from the support. The LED industrial control panel is electrically connected to the pressure sensor and the cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model allows the cylinder to push the push ring down before filling the bottle with high-pressure gas through the adapter cap, thereby pushing the bow-shaped swing plates on both sides to move closer together and fix the clamping block to the bottle body. This ensures that the bottle mouth is aligned with the sealing ring inside the adapter cap during the pressure test, preventing pressure leakage and thus achieving more accurate and scientific test data.

[0017] 2. This utility model uses a cylinder to push the adapter cap down, which in turn drives the push ring down. The push ring has a groove that squeezes the arc-shaped swing plate, which in turn pushes the two clamping blocks to clamp and position the bottle. It has the advantages of simple positioning structure, durability and easy maintenance. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figures 1-3 This embodiment of a pressure testing device for a liquid drug packaging bottle includes a support 1. In this embodiment, the testing device can be quickly installed through the support 1, and the support 1 is provided with screw holes.

[0027] Please combine Figure 1 As shown, a limiting platform 3 is fixedly connected to one side of the support 1. In this embodiment, four sliding rods 5 are slidably connected on the limiting platform 3. The sliding rods 5 can slide up and down along the inside of the limiting platform 3. The four sliding rods 5 are arranged in a circular array.

[0028] Please combine Figure 1 As shown, the lower ends of the four sliding rods 5 are all fixedly connected to a push ring 9. The push ring 9 is made of high manganese steel, a wear-resistant metal. In this embodiment, the push ring 9 is circular and has a hollow center.

[0029] Please combine Figure 3 As shown, in this embodiment, the push ring 9 has two push grooves 14. If in this embodiment, a conveyor belt is used to intermittently transport the drug liquid packaging bottle, the conveyor belt can pass between the two clamping blocks 8 so that the bottle body and bottle mouth are just located at the center line of the clamping block 8.

[0030] Please combine Figure 1As shown, two bow-shaped swing plates 7 are rotatably connected to the lower side of the limiting platform 3. The bow-shaped swing plates 7 have a bow-shaped structure. When the push ring 9 moves downward, the two bow-shaped swing plates 7 are pushed and closed by the push groove 14, and the clamping block 8 achieves the positioning function of the bottle body.

[0031] Conversely, when the push ring 9 moves upward, the two arc-shaped swing plates 7 are pushed open by the push groove 14, and the clamping block 8 releases the bottle body;

[0032] Please combine Figure 2 As shown, each bow-shaped swing plate 7 has a clamping block 8 fixedly connected to its lower end. The two bow-shaped swing plates 7 and the two push grooves 14 are respectively paired. The outer side of each bow-shaped swing plate 7 is slidably connected to the inner side of the corresponding push groove 14. The upper side of the limiting platform 3 is provided with a clamping drive mechanism that makes the two clamping blocks 8 move closer or further away from each other. The side of the limiting platform 3 is provided with a pressure resistance detection mechanism.

[0033] Please combine Figure 3 As shown, the clamping drive mechanism includes a cylinder 2 fixedly connected to the upper side of the limiting platform 3. The piston rod of the cylinder 2 passes downward through the limiting platform 3 and is fixedly connected to a three-way pipe 13. A bottle mouth adapter mechanism is provided at the lower end of the three-way pipe 13.

[0034] Please combine Figure 3 As shown, the bottle mouth adapter mechanism includes an adapter cover 6 that communicates with the lower end of the three-way tube 13. The internal dimensions of the lower side of the adapter cover 6 are approximately equal to the dimensions of the bottle mouth to be packaged. A sealing ring 16 is installed on the inner side of the adapter cover 6. The sealing ring 16 is an O-ring with good flexibility. A slot 15 is provided on the outer side of the adapter cover 6. The slot 15 is an annular slot structure. In this embodiment, the slot 15 is engaged with the push ring 9.

[0035] Please combine Figure 2 As shown, a pressure sensor 12 is installed on one side of the three-way pipe 13. The pressure sensor 12 can monitor the pressure inside the medicine bottle in real time after the high-pressure gas is injected and feed it back to the LED industrial control panel 4. The logic calculation program built into the LED industrial control panel 4 can receive data in real time and control the high-pressure gas pump 11 to start and stop.

[0036] Please combine Figure 1 As shown, the pressure resistance testing mechanism includes a high-pressure air pump 11 fixedly connected to one side of the limiting platform 3. A flexible hose 10 is connected between the lower side of the high-pressure air pump 11 and the three-way pipe 13. When the three-way pipe 13 moves up and down with the adapter cover 6, the flexible hose 10 can perform the function of expansion and contraction.

[0037] Please combine Figure 1 As shown, an LED control panel 4 is installed on the side of the limiting platform 3 away from the support 1. The LED control panel 4 is electrically connected to the pressure sensor 12 and the cylinder 2.

[0038] The implementation principle of the pressure detection device for a liquid medicine packaging bottle in this application embodiment is as follows: When the medicine bottle is transported from a distance to below the push ring 9 by the conveyor belt, the cylinder 2 is activated to push the three-way pipe 13 and the adapter cap 6 downward. The slide rod 5 slides downward along the limiting platform 3. Due to the slot 15 provided on the side of the adapter cap 6, the push ring 9 is pushed downward. The push ring 9 squeezes the bow-shaped swing plates 7 on both sides to move closer to each other through the push groove 14, so that the two clamping blocks 8 position and fix the bottle body from both sides. At this time, the high-pressure air pump 11 is activated, and high-pressure gas is injected into the adapter cap 6 and the medicine bottle through the hose 10 and the three-way pipe 13. At the same time, the pressure sensor 12 monitors the pressure in the adapter cap 6 and the medicine bottle in real time. When the pressure reaches the qualified pressure and the medicine bottle does not break or deform, it passes the pressure resistance test.

[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
