Description

Technical Field

[0001] The utility model relates to the technical field of sealing test equipment, in particular to a multi-station tube glass bottle sealing test device. Background Art

[0002] Many medicines on the market are packaged in tube glass bottles. The raw materials for production are high-borosilicate or low-borosilicate glass tubes. The glass tubes have different diameters and thicknesses. They are processed into different lengths through equipment as needed, and then the bottom and bottle mouth are processed. During the bottom and bottle mouth processing, high-temperature melting and mold shaping are generally used. In this process, the glass is prone to stress, which may cause severe damage to the bottle and make it unusable, or produce cracks and gaps that are difficult to observe with the naked eye, resulting in the risk of air and liquid leakage in the bottle. In addition, the storage of medicines needs to be isolated from the air. When there is a problem with the packaging, it will seriously affect the shelf life and performance of the medicine.

[0003] Therefore, it is necessary to test the sealing performance of the glass tube before adding the drug into the glass tube. However, the existing glass tube sealing performance testing device has many problems in the actual production and testing process, such as:

[0004] 1. The processing efficiency of tube glass bottles is very high, and the daily output can generally reach thousands or even tens of thousands. When it is necessary to fully control the product quality, conventional sealing test equipment is generally single-station, which is difficult to match the production efficiency;

[0005] 2. Usually, the vacuum pump of the glass bottle sealing test device is turned on only during the test. After the test, the vacuum pump is turned off and the vacuum environment disappears. However, during large-scale testing, the vacuum pump will be started and shut down frequently, which can easily cause damage to the vacuum pump and greatly affect the efficiency of the test;

[0006] 3. Each inspection station usually needs to be connected to multiple air pipes and air valves for air extraction or air intake operations at each station. Once a leak occurs somewhere, it will take a lot of time and effort to repair it. In addition, the increase in the number of air pipes and air valves will also increase the difficulty of installation. Utility Model Content

[0007] In order to solve the problems that the existing tube glass bottle sealing test device is difficult to match the mass market efficiency, too many gas circuits make installation and maintenance more difficult, and frequent starting and stopping of the vacuum pump causes damage to the vacuum pump, the utility model provides a multi-station tube glass bottle sealing test device.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-station tube glass bottle sealing test device, comprising a test table, a plurality of calibration seats are arranged at equal intervals on the top of the test table, the top of each calibration seat is detachably connected to a test seat, a mounting head is arranged in the center of the top of the test seat, a first sealing ring is arranged on the outer surface of the mounting head, a sample bottle is plugged and connected to the outer surface of the mounting head, an interface that can be connected to an external sealing tester is arranged on one side of each of the calibration seats, a valve seat assembly is connected to the top of each of the calibration seats through the test table, a buffer tank assembly is arranged below the valve seat assembly, a vacuum pump is connected to one side of the buffer tank assembly, and an air pipe is connected between the buffer tank assembly and each of the valve seat assemblies.

[0009] Preferably, the test seat and the calibration seat are connected by fixing bolts, a second sealing ring is provided at the connection between the test seat and the calibration seat, and the calibration seat and the test table are connected by fixing bolts.

[0010] Preferably, the valve seat assembly includes a valve seat, which is fixedly connected to the test bench by fixing bolts, a first air channel connected to the calibration seat is arranged on the top of the valve seat, the other end of the first air channel is connected to the second air channel, one end of the second air channel is sealed and connected to a vacuum pressure sensor, and the other end is connected to a third air channel, a fourth air channel is arranged on the side of the valve seat assembly away from the vacuum pressure sensor, a first air path interface is arranged at one end of the fourth air channel and the other end is connected to a fifth air channel, the first air path interface is through-connected to one end of the air pipe, and a first solenoid valve is arranged on one side of the valve seat between the third air channel and the fifth air channel.

[0011] Preferably, the valve seat assembly also includes a sixth air duct, one end of the sixth air duct is connected to the third air duct, and the other end is provided with a second solenoid valve. A seventh air duct is opened on the side of the valve seat away from the first solenoid valve, one end of the seventh air duct is connected to the second solenoid valve, and the other end is connected to a muffler.

[0012] Preferably, the cache tank assembly includes a cache tank, both ends of which are provided with support frames by fixing bolts, one side of the cache tank is fixedly connected with a plurality of second air path interfaces, the second air path interfaces are through-connected with one end of the air pipe, and one end of the cache tank is provided with an air outlet interface through the support frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By setting up multiple groups of test stations, multiple groups of test seats, calibration seats and valve seat components operate together, and each group is connected to the buffer tank component and the vacuum pump respectively, so that each station does not affect each other, the efficiency of the inspection is improved, and the problem of mismatch between the inspection efficiency of the sealing test equipment and the production efficiency of the tube glass bottle is overcome;

[0015] 2. By assembling a buffer tank, vacuum can be pre-stored, and a vacuum pump is used to continuously extract vacuum from the buffer tank. This overcomes the problem that in the case of a large number of test needs, the vacuum pump is started during the test and shut down after the test. The vacuum pump is started and stopped frequently during ordinary single-station testing, which easily causes damage to the vacuum pump. The buffer tank can always maintain a certain vacuum degree, and the vacuum pump continues to work, which further improves the detection efficiency;

[0016] 3. Through the valve seat assembly, a valve seat and multiple air passages are set, and the connection state is controlled by the first solenoid valve, which reduces the installation and maintenance difficulties caused by the use of the air path;

[0017] 4. By providing a detachable test seat, when the specification and size of the sample bottle changes, the test seat adapted to the sample bottle can be replaced by removing the fixing bolts, thereby improving the applicability of the test device. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] See also Figure 1-3As shown, a multi-station controlled glass bottle sealing test device includes a test table 1, which is fixedly installed on an external bracket in the test site. A plurality of calibration seats 2 are arranged at equal intervals on the top of the test table 1. The utility model arranges five calibration seats 2, and each of the calibration seats 2 is detachably connected to the top of a test seat 3, and the test seat 3 is connected to the calibration seat 2 by fixing bolts. When the size of the test seat 3 cannot adapt to the size of the sample bottle 10, the fixing bolts are loosened to disassemble the test seat 3, and the test seat 3 that can adapt to the sample is replaced, thereby improving the applicability of the entire device; a second sealing ring 31 is arranged at the connection between the test seat 3 and the calibration seat 2, which improves the sealing between the two and ensures the smooth progress of the test, and the calibration seat 2 is connected to the test table 1 by fixing bolts, and the assembly of the calibration seat 2, the test seat 3 and the test table 1 is completed by the connection of the fixing bolts.

[0031] A mounting head 4 is arranged at the top center of the test seat 3, and a first sealing ring 5 is arranged on the outer surface of the mounting head 4. A sample bottle 10 is plugged and connected to the outer surface of the mounting head 4. The opening of the sample bottle 10 is aligned with the mounting head 4 and the first sealing ring 5 for insertion, and the first sealing ring 5 is used to isolate the sample bottle from the outside air. This sealing method is combined with a vacuum testing method to reduce the use of a sample bottle clamping device, avoid damage to the sample and influence on the results, and the sample bottle 10 can be quickly pulled out of the fixture and quickly installed, thereby improving the test efficiency.

[0032] One side of each calibration seat 2 is provided with an interface 6 which can be connected to an external sealing tester. After being connected to the interface 6, the external sealing tester can detect the pressure change in the sample bottle 10, and judge whether there are cracks or gaps in the sample bottle 10 based on the change. When there is no testing task, a plug can be installed to prevent dust from entering.

[0033] like Figure 4-6As shown, the top of each calibration seat 2 passes through the test table 1 and is respectively connected to a valve seat assembly 7, wherein the valve seat assembly 7 includes a valve seat 71, and the valve seat 71 is fixedly connected to the test table 1 by fixing bolts.

The inside of the valve seat assembly 7 is far away from the vacuum pressure sensor 74. A fourth air channel 76 is provided on one side of the air pressure sensor 74, and a first air path interface 77 is provided at one end of the fourth air channel 76. The gas is drawn away through the first air path interface 77, and the other end is connected to the fifth air channel 78. The first air path interface 77 is through-connected to one end of the air pipe 9, and a first solenoid valve 79 is provided on one side of the valve seat 71 between the third air channel 75 and the fifth air channel 78. By setting the first solenoid valve 79, the connection state between the third air channel 75 and the fifth air channel 78 can be controlled, and the connection state between the gas in the sample bottle 10 and the buffer tank assembly 8 can be controlled.

[0034] Furthermore, the valve seat assembly 7 also includes a sixth air duct 710, one end of which is connected to the third air duct 75, and the other end is provided with a second solenoid valve 711.

[0036] When the device is used, an external sealing tester is connected to the interface 6, and then the first solenoid valve 79 is controlled to be closed, so that the sample bottle 10 and the calibration seat 2 are isolated from the buffer tank assembly 8 and the vacuum pump. At this time, the buffer tank 81 is in a vacuum environment, and the sample bottle 10 is inserted into the mounting head 4, and the first solenoid valve 79 is opened and connected to the buffer tank assembly 8 to evacuate the sample bottle 10. At this time, the vacuum pump is in a continuous working state, which is used to adjust the pressure in the sample bottle, avoiding multiple starts and stops of the vacuum pump. By observing the sealing tester, it is determined whether there are cracks or gaps in the sample bottle 10.
