Description

Technical Field

[0001] This utility model relates to the technical field of bottle body inspection devices for production lines, and more specifically, to bottle body inspection devices for injection liquid production lines. Background Technology

[0002] With the continuous development of pharmaceutical manufacturing technology and the increasing improvement of pharmaceutical quality standards, the inspection of injection vials has become particularly important in the pharmaceutical manufacturing process. As a key piece of equipment to ensure pharmaceutical quality, the stability and accuracy of the injection vial inspection device are directly related to the safety and efficacy of the pharmaceuticals.

[0003] Before production on an injectable solution production line, it is usually necessary to check for leaks in the vials. Specifically, this involves using a vial detection device. Commercially available vials typically inject the solution into the vial first, then observe for leaks. While this method effectively detects leaks, any leaks contaminate the solution inside, rendering it unusable and wasteful. This lack of pre-injection leak detection negatively impacts the overall effectiveness. Therefore, we propose a vial detection device for injectable solution production lines. Utility Model Content

[0004] The purpose of this invention is to provide a bottle inspection device for injection production lines to address the deficiencies mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bottle inspection device on an injection production line includes a production line support frame, on which a support frame is fixedly installed. A leakage detection component is mounted on the support frame. The leakage detection component includes two symmetrically arranged first cylinders fixedly mounted on the top plate of the support frame. A fixing plate is provided at the end of the telescopic shaft of each of the two first cylinders. A vertically arranged air storage cylinder is fixedly installed at the center of the fixing plate. A vertical pipe is fixedly installed at the bottom of the air storage cylinder, and a pressure gauge is fixedly installed on the vertical pipe. A connector is fixedly installed at the bottom of the vertical pipe, and a rubber sealing cap is fixedly installed on the top of the connector. A second cylinder is fixedly installed at the top of the air storage cylinder. A piston is provided at the end of the telescopic shaft of the second cylinder, and the piston is located inside the air storage cylinder and slidably connected to it.

[0007] Preferably, a fixing plate is fixedly installed at the end of the telescopic shaft of the first cylinder, and the fixing plate is fixedly installed on the bottom surface of the two fixing plates.

[0008] Preferably, the gas storage cylinder is a transparent cylindrical structure, and the surface of the gas storage cylinder is provided with scale lines arranged along the height direction of the gas storage cylinder.

[0009] Preferably, a fixing ring is fixedly installed at the top of the air storage cylinder, and the second cylinder is fixedly installed on the fixing ring.

[0010] Preferably, an annular groove is provided on the upper surface of the fixing ring, and a sealing ring is engaged in the annular groove, with the second cylinder abutting against the sealing ring and the fixing ring.

[0011] Preferably, a perforated disc is fixedly installed at the end of the telescopic shaft of the second cylinder, and a central disc is fixedly installed on the top of the piston. The central disc and the perforated disc are fixedly connected by a plurality of fastening screws.

[0012] Preferably, the size of the piston is adapted to the size of the gas storage cylinder, and the size of the sealing ring is adapted to the size of the annular groove.

[0013] Preferably, a control host is fixedly installed on the side plate of the support frame, and an alarm is installed on the control host.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the designed leakage detection component, ensures that during use, after the insertion tube is inserted into the bottle body, the rubber sealing cap is placed against the bottle mouth for sealing. Then, the second cylinder drives the piston to move downward, compressing the gas in the gas storage cylinder into the bottle body. The change in pressure gauge indicates whether the bottle body is leaking, thus achieving the effect of detecting whether the bottle body is leaking before liquid injection.

[0016] 2. This utility model uses scale lines to observe the position of the piston and a sealing ring to seal the top of the air storage cylinder and the second cylinder to prevent leakage. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Please see Figures 1-5 This utility model provides a technical solution: a bottle body detection device on an injection production line, including a production line support 1, a support frame 10 fixedly installed on the production line support 1, a leakage detection component 2 provided on the support frame 10, the leakage detection component 2 including two symmetrical first cylinders 20 fixedly installed on the top plate of the support frame 10, a fixing plate 21 provided at the end of the telescopic shaft of the two first cylinders 20, a vertically arranged air storage cylinder 22 fixedly installed at the center of the fixing plate 21, a vertical pipe 23 fixedly installed at the bottom end of the air storage cylinder 22, a pressure gauge 231 fixedly installed on the vertical pipe 23, a insertion pipe 25 fixedly installed at the bottom end of the vertical pipe 23, a rubber sealing cap 24 fixedly installed on the top pipe of the insertion pipe 25, the insertion pipe 25 is used to be inserted into the bottle body, and the rubber sealing cap 24 is used to press against the bottle mouth for sealing operation;

[0027] Specifically, a second cylinder 27 is fixedly installed on the top of the air storage cylinder 22. A piston 28 is provided at the end of the telescopic shaft of the second cylinder 27. The piston 28 is located inside the air storage cylinder 22 and is slidably connected to the air storage cylinder 22, so as to realize the operation of pumping and releasing air by moving the piston 28 up and down.

[0028] In this embodiment, a fixing plate 201 is fixedly installed at the end of the telescopic shaft of the first cylinder 20. The fixing plate 21 is fixedly installed on the bottom surface of the two fixing plates 201 by multiple fastening screws, which facilitates the fixing and installation operation.

[0029] Specifically, the gas cylinder 22 has a transparent cylindrical structure for observation and operation; the surface of the gas cylinder 22 is provided with scale lines 221 arranged along the height direction of the gas cylinder 22, and the scale lines 221 are used to display the operation.

[0030] Furthermore, a fixing ring 26 is fixedly installed at the top of the air storage cylinder 22, and the second cylinder 27 is fixedly installed on the fixing ring 26; an annular groove 261 is provided on the upper surface of the fixing ring 26, and a sealing ring 262 is engaged in the annular groove 261. The second cylinder 27 abuts against the sealing ring 262 and the fixing ring 26, so that leakage is unlikely between the fixing ring 26 and the second cylinder 27.

[0031] In addition, a perforated disc 271 is fixedly installed at the end of the telescopic shaft of the second cylinder 27, and a center disc 281 is fixedly installed on the top of the piston 28. The center disc 281 and the perforated disc 271 are fixedly connected by multiple fastening screws, which facilitates the fixed installation and disassembly replacement operations.

[0032] It is worth noting that the dimensions of the piston 28 are matched with the dimensions of the air reservoir 22, and the dimensions of the sealing ring 262 are matched with the dimensions of the annular groove 261, for stable assembly.

[0033] It is worth noting that a control host 11 is fixedly installed on the side plate of the support frame 10. An alarm 12 is installed on the control host 11. The pressure data detected by the pressure gauge 231 is transmitted to the control host 11 through a transmission cable. By setting a corresponding pressure threshold in the control host 11, when the pressure gauge 231 detects that the pressure value in the bottle is less than the threshold set in the control host 11, it proves that the bottle is leaking. The control host 11 will control the alarm 12 to sound an alarm, which is convenient for staff to check in time.

[0034] Finally, it should be noted that the components involved in this utility model, such as the first cylinder 20, pressure gauge 231, second cylinder 27, control host 11, and alarm 12, are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0035] When using the bottle body detection device on the injection production line of this utility model, the entire equipment is operated under sterile conditions. As the bottle body is conveyed on the conveyor line to the area directly below the insertion tube 25, the first cylinder 20 is activated and put into operation. When the first cylinder 20 is activated, its telescopic shaft extends, causing the insertion tube 25 to be inserted into the bottle body. At this time, the rubber sealing cap 24 presses against the bottle mouth to seal it. Then, the second cylinder 27 is activated and put into operation. When the second cylinder 27 is activated, its telescopic shaft extends, causing the piston 28 to move downward, thereby squeezing the gas in the gas storage cylinder 22 into the bottle body. At this time, observe whether the value of the pressure gauge 231 changes. If the value of the pressure gauge 231 is continuously decreasing, it indicates that the bottle body is leaking air.

[0036] After the test is completed, the first cylinder 20 continues to work, and its telescopic shaft shortens, causing the insertion tube 25 to move upward and return to its initial position. At the same time, the second cylinder 27 works, and its telescopic shaft shortens, causing the piston 28 to move upward and return to its initial position. As the piston 28 moves upward, it continues to draw gas into the gas storage cylinder 22.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
