Abstract
Description
Technical Field
[0001] This utility model relates to a detection device, and in particular to a detection device for plastic medicine bottles. Background Technology
[0002] In the pharmaceutical industry, plastic medicine bottles are commonly used drug packaging containers, and their airtightness is crucial. Good airtightness is a key factor in ensuring stable drug quality and preventing deterioration due to moisture, oxidation, and other factors. However, for testing the airtightness of plastic medicine bottles, manual inspection is the most common method. Workers hold the bottles and visually inspect them to determine if there are any leaks, which is time-consuming, labor-intensive, and inefficient. Furthermore, manual visual inspection has significant limitations. The human eye can only identify relatively obvious cracks or holes. Tiny gaps in the bottle are difficult to detect with the naked eye, yet these minute gaps allow outside air and moisture to slowly seep into the bottle, which can damage the quality of the drug over time. Manual inspection, relying solely on the naked eye, cannot effectively control these subtle airtightness issues. Utility Model Content
[0003] The purpose of this invention is to provide a detection device for plastic medicine bottles to solve the above-mentioned technical problems.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A testing device for plastic medicine bottles includes an L-shaped base. A top plate is fixedly mounted on the top of the L-shaped base, and the top plate is opposite to and parallel to the bottom of the L-shaped base. Two electric push rods are symmetrically arranged below the top plate, and the mounting ends of the electric push rods are fixedly connected to the top plate. A movable plate is arranged below the two electric push rods, and the movable ends of the two electric push rods are respectively fixedly connected to the movable plate. Several docking sleeves that can seal and mate with the mouth of the plastic medicine bottle are arranged below the movable plate. The docking sleeves have a conical structure, and an annular groove is formed on the horizontal direction of the docking sleeve, and several annular grooves are spaced apart in the vertical direction to accommodate medicine bottles with different mouth sizes. Several liquid-holding devices with open tops are arranged at the bottom of the L-shaped base, and the several liquid-holding devices are respectively arranged corresponding to the several docking sleeves.
[0006] Furthermore, based on the aforementioned solution, in an improved solution, the movable plate is provided with a plurality of placement holes spaced apart, and the plurality of placement holes are respectively arranged corresponding to a plurality of liquid holding devices; it also includes a rotating mechanism, the rotating mechanism including a rotating rod, a bearing and a motor, the outer ring of the bearing is fixedly embedded in the placement hole, one end of the rotating rod is interference-fitted into the inner ring of the bearing and is connected to the output end of the motor for transmission, and the other end of the rotating rod is fixedly connected to the mating sleeve. When the motor starts, the rotating rod and the inner ring of the bearing rotate.
[0007] Furthermore, the outer circumference of the rotating rod is provided with three flanges at equal intervals. The flanges extend radially outward along the rotating rod. The two adjacent rotating rods are connected by belt drive and the rotating rod is connected to the output end of the motor. The belt is movably sleeved between the two flanges of each rotating rod.
[0008] Furthermore, based on the aforementioned solution, an improved solution further includes an inflation mechanism, which comprises an inflation machine and an inflation pipe. The inflation machine is fixedly mounted on the movable plate, and the air outlet of the inflation machine is connected and communicates with the air inlet of the inflation pipe. The air outlet of the inflation pipe includes several branch pipes, which are respectively arranged corresponding to several docking sleeves. The branch pipes pass through the movable plate, the rotating rod, and the docking sleeves sequentially from above the movable plate and exit from below the docking sleeves, so that air can be injected into the plastic medicine bottle that is sealed and docked with the docking sleeve.
[0009] Furthermore, the connecting sleeve is made of elastic material, which allows the connecting sleeve to be firmly fitted onto the mouth of the medicine bottle and to seal the inside of the bottle.
[0010] Furthermore, the liquid-containing device has a cylindrical structure and is made of a transparent material for easy observation.
[0011] By adopting the above technical solution, this utility model has the following beneficial effects:
[0012] 1. This utility model, using an L-shaped base, top plate, electric push rod, movable plate, docking sleeve, and liquid-holding device, allows for testing by aligning the plastic medicine bottle coaxially with the docking sleeve, then clamping the bottle opening upwards onto the annular groove. Utilizing the elastic deformation of the docking sleeve, the bottle is securely fitted to the sleeve, ensuring a seal inside. Finally, the bottle is immersed in the liquid-holding device, and the presence of air bubbles around the bottle is observed to determine its seal. This solves the problem of manual inspection where small gaps in medicine bottles are difficult to distinguish visually, and allows for simultaneous inspection of multiple plastic medicine bottles, improving both efficiency and quality.
[0013] 2. This utility model allows the plastic medicine bottle to rotate during the testing process through a rotating mechanism, which allows for observation of the airtightness of other surfaces around the medicine bottle, thus improving the flexibility of the device.
[0014] 3. This utility model uses an inflation mechanism to inject appropriate gas into the plastic medicine bottle that is sealed with the docking sleeve, avoiding excessively small gaps and inconspicuous bubble formation, thus further improving the practicality of the device.

Detailed Implementation
[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] See Figures 1-3 This embodiment of a detection device for plastic medicine bottles includes an L-shaped base 1, a top plate 2, electric push rods 3, and a top plate 2 fixedly mounted on the top of the L-shaped base 1. The top plate 2 is opposite to and parallel to the bottom of the L-shaped base 1. Two electric push rods 3 are symmetrically arranged on the left and right sides below the top plate 2. The mounting ends of the electric push rods 3 are fixedly mounted on the top plate 2 by bolts and are arranged vertically. A movable plate 4 is arranged below the two electric push rods 3. The movable ends of the two electric push rods 3 are fixedly welded to the left and right sides of the movable plate 4, so that the movable plate 4 can move up and down with the movable ends of the electric push rods 3. Several mating sleeves 7 are arranged below the movable plate 4. The mating sleeves 7 are specifically conical in shape and made of elastic material, such as rubber. The mating sleeves 7 have annular grooves 71 along the horizontal direction and several annular grooves 71 spaced apart along the vertical direction. During testing, the staff aligns the plastic medicine bottle coaxially with the docking sleeve 7, and then places the bottle opening upwards onto the annular groove 71. The annular groove 71 engages with the bottle opening. Since the docking sleeve 7 is made of elastic material, it resets after being inserted, ensuring a secure fit and sealing of the bottle opening. The docking sleeve 7 is conical and has multiple annular grooves 71 to accommodate medicine bottles of different sizes, improving the device's practicality. The bottom of the L-shaped base 1 has several liquid-holding devices 8 with open tops for holding the test liquid. These devices are arranged corresponding to several docking sleeves 7. The liquid-holding devices 8 are cylindrical and made of transparent material. During testing, the sealed medicine bottle is immersed in the liquid-holding device 8, and the presence of air bubbles around the bottle is observed to determine if the bottle is properly sealed.
[0021] Based on the aforementioned scheme, as a further improvement, the detection device also includes a rotating mechanism 6, which includes several rotating rods 61, several bearings 62, a motor 63, and several belts 64. Several placement holes 41 are provided on the movable plate 4 corresponding to the liquid holding device 8. The outer ring of the bearing 62 is fixedly embedded in the placement hole 41. One end of the rotating rod 61 is interference-fitted into the inner ring of the bearing 62, and the other end of the rotating rod 61 is fixedly sleeved with the docking sleeve 7. Three flanges 611 are evenly spaced on the outer periphery of the rotating rod 61 (below the movable plate 4). The cross-section of two adjacent flanges 611 is an I-shaped structural steel. The flanges 611 are integrally formed and extend radially outward from the rotating rod 61. Several belts 64 are movably sleeved between pairs of adjacent rotating rods 61 and between the rotating rod 61 and the output end of the motor 63. When the motor 63 starts, it drives the rotating rods 61 to rotate through the belts 64. The rotating rods 61 drive the docking sleeve 7 to rotate. The flanges 611 of the rotating rods 61 limit the movement of the belts 64. The rotating mechanism 6 allows the plastic medicine bottle to rotate during the testing process, enabling observation of the airtightness of other surfaces on the outer periphery of the medicine bottle, thus improving the flexibility of the device.
[0022] Based on the aforementioned scheme, as a further improvement, the detection device also includes an inflation mechanism 5, which includes an inflation machine 51 and an inflation pipe 52. The inflation machine 51 is fixedly installed on the movable plate 4. The air outlet of the inflation machine 51 is connected and communicates with the air inlet of the inflation pipe 52. The air outlet of the inflation pipe 52 includes several branch pipes 521, which are respectively arranged with several docking sleeves 7. The branch pipes 521 pass through the movable plate 4, the rotating rod 61 and the docking sleeves 7 from the top of the movable plate 4 in sequence, and exit from the bottom of the docking sleeves 7, so as to fill the plastic medicine bottle sealed with the docking sleeves 7 with appropriate gas. When the plastic medicine bottle is not well sealed, the inflation device 5 makes the bubbles more obvious.
[0023] The working principle of this utility model is as follows: First, the operator fills the water-holding device 8 with water or disinfectant liquid. Then, holding the medicine bottle whose airtightness needs to be tested with its mouth facing upwards, the operator seals it onto the docking sleeve 7. At this time, the electric push rod 3 is activated, which drives the docking sleeve 7 downwards until the body of the medicine bottle is completely immersed in the liquid-holding device 8 (with the mouth facing outwards and above the liquid surface). Then, the inflation mechanism is activated, and gas is released from the inflation tube 52, passing through various branch tubes 521 to reach the medicine bottle. The operator observes the medicine bottle from the front side of the transparent water-holding device 8 to check for air bubbles. The rotating mechanism 6 rotates the medicine bottle to observe the airtightness of other sides of the bottle. As mentioned above, this utility model solves the problem that it is difficult to distinguish small gaps in medicine bottles with the naked eye during manual inspection. It can simultaneously inspect multiple plastic medicine bottles, improving inspection efficiency and quality.
