Abstract
Description
Technical Field
[0001] This utility model relates to the field of blister box testing technology, specifically a blister box sealing test device. Background Technology
[0002] Blister box sealing test refers to the evaluation of the sealing performance of blister box packaging through a series of test methods to ensure that it can effectively prevent the leakage of gas, liquid or solid particles. This test is crucial for ensuring product quality, extending shelf life, preventing contamination and ensuring safety.
[0003] Regarding the aforementioned technologies, when conducting a sealing test on a blister pack, the main leakage points are mostly concentrated at the seam between the pack body and the lid. When the blister pack is closed and in a good sealing state, the gas pressure inside the blister pack will increase accordingly. Conversely, when the gas pressure inside the blister pack rises to a certain pressure value, it will gradually decrease after inflation stops.
[0004] To address this issue, the present invention provides a device for detecting the sealing performance of blister packs. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a blister box sealing detection device, which solves the aforementioned problems.

[0007] The testing assembly includes a stand, the bottom wall of which is fixedly connected to the top wall of the test platform. A cross groove is provided on the inner wall of the stand. A servo motor is fixedly installed on the top wall of the stand. The power shaft of the servo motor passes through the stand and is fixedly installed with an adjusting screw. A cross block is screwed onto the outer wall of the adjusting screw. A lifting platform is fixedly installed on the left side wall of the cross block. An installation port is provided on the top wall of the lifting platform. A discharge pipe is installed on the inner wall of the installation port. A sealing pipe matching the detection port is installed at the bottom end of the discharge pipe. An air pump is installed on the top wall of the test platform. The air outlet of the air pump is connected to a connecting pipe. A flexible hose is connected to the left end of the connecting pipe. The top end of the flexible hose is connected to the top end of the discharge pipe. A pressure sensor is placed on the inner wall of the box.
[0008] Using the above technical solution, the testing component can quickly test the airtightness of the box. The main method is to inflate the box with air and monitor the changes in air pressure inside the box in real time through an air pressure sensor, thereby clearly identifying whether there is an air leakage problem.
[0009] Furthermore, the outer wall of the cross block is slidably connected to the inner wall of the cross groove, a positioning ring is fixedly installed on the outer wall of the sealing tube, and the air inlet of the air pump is connected to an air inlet pipe, which is connected to the outside.
[0010] The above technical solution allows the outer wall of the cross block to slide against the inner wall of the cross groove, preventing the cross block from flipping over during movement.
[0011] Furthermore, the components include a C-shaped frame, the inner wall of which is fitted to the outer wall of the box, and the bottom wall of the C-shaped frame is fixedly connected to the top wall of the test bench.
[0012] Through the above technical solution, the C-shaped frame mainly serves to limit the outer wall of the box.
[0013] Furthermore, a C-shaped seat is fixedly installed on the right side wall of the C-shaped frame, and an electric push rod is fixedly installed on the right side wall of the C-shaped seat. The movable end of the electric push rod slides through the C-shaped seat and a push-out seat is fixedly installed thereon.
[0014] Through the above technical solution, the electric push rod can push the box away from the inner wall of the C-shaped frame through the push-out seat.
[0015] Furthermore, an ejection slot is provided on the side wall of the C-shaped frame at the position corresponding to the ejection seat.
[0016] The above technical solution mainly facilitates the movement of the ejector seat by setting up the ejector slot.
[0017] Furthermore, an abutment seat is fixedly installed on the left side of the top wall of the test stand, and a protective pad is fixedly installed on the right side wall of the abutment seat.
[0018] Through the above technical solution, the cooperation between the abutment seat and the protective pad can limit the movement of the box at the point of being pushed after the test is completed.
[0019] Furthermore, the protective pad has an installation groove on its side wall, a marking block is installed on the inner wall of the installation groove, and a waste frame is fixedly installed on the rear of the top wall of the test bench.
[0020] The above technical solution enables the marking of boxes that fail the inspection. Beneficial effects
[0021] This invention provides a device for detecting the sealing performance of blister packs. Compared with the prior art, it has the following advantages:
[0022] (1) The blister box sealing test device can continuously test the sealing of the blister box by inflating it through the setting of the test components. By detecting whether there is a change in the internal air pressure of the blister box, the airtightness of the blister box can be determined. The overall operation is relatively simple and the time consumption is short, which has good testing efficiency.
[0023] (2) The blister box sealing detection device, through the setting of the ejection component, can make different discharge states according to different test results after the sealing test of the blister box is completed. When there is a leak in the blister box, it will be marked, which makes it convenient for staff to quickly identify and deal with it. Attached Figure Description

[0033] Test assembly 5 includes a stand 51, the bottom wall of which is fixedly connected to the top wall of test platform 1. A cross groove 52 is formed in the inner wall of the stand 51. A servo motor 53 is fixedly installed on the top wall of the stand 51. The power shaft of the servo motor 53 passes through the stand 51 via a bearing and is fixedly installed with an adjusting screw 54. A cross block 55 is screwed onto the outer wall of the adjusting screw 54. A lifting platform 56 is fixedly installed on the left side wall of the cross block 55. An installation port 57 is formed in the top wall of the lifting platform 56. A discharge pipe 58 is installed on the inner wall of the installation port 57. The bottom end of the discharge pipe 58 is... The test bench 1 is equipped with a sealing tube 59 that matches the test port 6. An air pump 514 is installed on the top wall of the test bench 1. The air outlet of the air pump 514 is connected to a connecting tube 513. The left end of the connecting tube 513 is connected to a flexible hose 512. The top end of the flexible hose 512 is connected to the top end of the discharge tube 58. A pressure sensor 510 is placed on the inner wall of the box 3. The outer wall of the cross block 55 is slidably connected to the inner wall of the cross groove 52. A positioning ring 511 is fixedly installed on the outer wall of the sealing tube 59. The air inlet of the air pump 514 is connected to an air inlet pipe, which is connected to the outside.
[0034] In this embodiment of the utility model, the purpose of this setting is that the test component 5 is set up so that when it is working, air is supplied through the inside of the box 3 and the air pressure sensor 510 monitors in real time whether there is a change in the air pressure inside the box 3 and the box cover 4 assembly. When there is a change, it proves that the box 3 is leaking air. Conversely, if the air pressure remains unchanged, the box 3 has good sealing performance.
[0035] Example 2:
[0036] Please see Figures 1-5This embodiment provides a technical solution based on embodiment one: the ejection component 2 includes a C-shaped frame 25, the inner wall of the C-shaped frame 25 is attached to the outer wall of the box 3, the bottom wall of the C-shaped frame 25 is fixedly connected to the top wall of the test platform 1, a C-shaped seat 27 is fixedly installed on the right side wall of the C-shaped frame 25, an electric push rod 28 is fixedly installed on the right side wall of the C-shaped seat 27, the movable end of the electric push rod 28 slides through the C-shaped seat 27 and an ejection seat 29 is fixedly installed, an ejection groove 26 is opened on the side wall of the C-shaped frame 25 and at the position corresponding to the ejection seat 29, an abutment seat 21 is fixedly installed on the left side of the top wall of the test platform 1, a protective pad 22 is fixedly installed on the right side wall of the abutment seat 21, an installation groove 23 is opened on the side wall of the protective pad 22, a marking block 24 is installed on the inner wall of the installation groove 23, and a waste frame 210 is fixedly installed at the rear of the top wall of the test platform 1;
[0037] In this embodiment of the utility model, the purpose of this setting is that, after the sealing check of the box body 3 is completed, the electric push rod 28 pushes the push seat 29 through the push groove 26 to push the box body 3 away from the C-shaped frame 25. When there is an air leakage problem, the corresponding box body 3 is pushed to the position of the marking block 24 for marking, which is convenient for the staff to identify. When the sealing is good, it can be pushed out of the C-shaped frame 25. The waste box 210 is mainly used to place the blister box waste.
[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0039] Working principle: Before operation, the electric push rod 28, servo motor 53, air pressure sensor 510 and air pump 514 are electrically connected through an external power supply and controller. When testing the box 3, the air pressure sensor 510 is first placed inside the box 3, the box cover 4 is placed on the outside of the box 3, and the box 3 is placed in the inner wall of the C-shaped frame 25 to fit together.
[0040] Then, a sealing test was conducted on the box body 3. The servo motor 53 drove the adjusting screw 54 to rotate. When the adjusting screw 54 rotated, it would drive the cross block 55 to move linearly along the outer wall of the adjusting screw 54 and the inner wall of the cross groove 52. The cross block 55 would also drive the lifting platform 56 and the discharge pipe 58 to descend. The discharge pipe 58 would drive the movable hose 512 and the sealing pipe 59 to descend, so that the sealing pipe 59 could enter the inner wall of the detection port 6 at the top of the box cover 4. Since the sealing pipe 59 is made of rubber, it has good sealing performance. At the same time, the bottom wall of the positioning ring 511 abuts and fixes against the top wall of the box cover 4.
[0041] The air pump 514 is started to supply air into the box 3 through the connecting pipe 513, the movable hose 512 and the discharge pipe 58, and the air pressure sensor 510 monitors the air pressure inside the box 3 in real time. When the air pressure inside the box 3 reaches the predetermined value.
[0042] An electric valve is installed on the outer wall of the connecting pipe 513 to control the air supply of the connecting pipe 513. After the electric valve is closed, the air pressure sensor 510 monitors in real time whether the air pressure inside the box 3 is decreasing. When the internal air pressure remains unchanged, it means that the overall sealing of the box 3 and the lid 4 is good. Otherwise, it means that the air tightness is poor and there is a leakage problem.
[0043] Next, the reverse rotation of the servo motor 53's power shaft causes the sealing tube 59 to disengage from the inner wall of the detection port 6. The detection results are then collected by the external controller. When the sealing is good, the electric push rod 28 pushes the ejector seat 29 through the ejector groove 26 to push the box 3 outward and disengage it from the C-shaped frame 25. When there is air leakage, the electric push rod 28 pushes the ejector seat 29 to push the box 3 towards the position of the abutment seat 21 and the protective pad 22, so that the box 3 contacts the marking block 24 for marking, making it easier for staff to identify the box 3.
