Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag detection, in particular to a packaging bag sealing detection device. Background Art

[0002] Packaging bags refer to bags used to package various supplies, which make it convenient to transport and store goods during the production and circulation process. There are two ways to make bags. One is that the packaging manufacturer uses roll film to fill on an automatic packaging machine and form and package into various packaging bags; the other is that the bag making machine makes various packaging bags and then fills the contents. Since the packaging bags only need to be sealed to package items, they are widely used in daily life, industrial production and medical treatment. Among them, the requirements for packaging bags used for medical treatment are particularly strict. Medical packaging bags should be able to keep the contents of the product intact while preventing the invasion of microorganisms. Therefore, medical packaging bags need to have good sealing properties. Therefore, in the production process of medical packaging bags, the sealing properties of the packaging bags need to be tested, and the sealing properties of the packaging bags need to be tested using a sealing detection device.

[0003] In the prior art, patent number CN202321095257.0 proposes a medical packaging bag sealing detection device. During the detection process, especially when high-pressure gas is injected into the bag, the medical packaging bag to be tested is prone to bursting. This is because most medical packaging bags are sealed in the form of heat-sealed edges on one or both sides. Under a certain high pressure, the high-pressure gas may burst the sealed edge, causing the bag body to be damaged and unable to be detected. However, the patent CN202321095257.0 cannot simultaneously detect multiple packaging bags. After the detection of one packaging bag is completed, the packaging bag needs to be replaced to continue the detection, resulting in a cumbersome process for detecting multiple packaging bags. Therefore, a packaging bag sealing detection device is proposed. Utility Model Content

A mounting plate 5 is fixedly arranged inside the mounting frame 4, a lower fixed magnet 6 is fixedly arranged on the top of the mounting plate 5, an upper fixed magnet 7 is adsorbed on the top of the lower fixed magnet 6, and a movable plate 8 is fixedly arranged on the top of the upper fixed magnet 7. The right side of the detection box 1 is provided with There is a vacuum pumping assembly, which includes a bottom plate 13 arranged on the right side of the detection box 1, a vacuum pump 14 is fixedly arranged on the top of the bottom plate 13, an outlet pipe 15 is fixedly arranged on the outlet end of the vacuum pump 14, an inlet pipe 16 is fixedly arranged on the inlet end of the vacuum pump 14, and an exhaust pipe 17 is fixedly arranged on the inlet end of the inlet pipe 16. The inlet end of the exhaust pipe 17 passes through the detection box 1 and extends to the inside of the detection box 1. Through the arrangement of the vacuum pump 14, the outlet pipe 15, the inlet pipe 16 and the exhaust pipe 17, it is convenient to evacuate the detection box 1, so as to facilitate the inside of the detection box 1 and the packaging bag. A pressure difference is formed inside, which makes it easy to apply squeezing force to the packaging bag. Through the arrangement of the box cover 3, the mounting frame 4, the mounting plate 5, the lower fixed magnet 6, the upper fixed magnet 7, the movable plate 8 and the vacuum assembly, it is convenient to detect the sealing of multiple packaging bags at the same time, avoiding the situation where the sealing of only one packaging bag can be tested at a time, resulting in a decrease in the packaging bag testing speed, thereby speeding up the packaging bag testing speed. The lower fixed magnet 6 and the upper fixed magnet 7 are used to clamp the side of the packaging bag, avoiding the surface of the packaging bag being blocked and causing errors in the test results.

[0023] Specifically, a connecting component is provided on the front side of the movable plate 8, and the connecting component includes a flip plate 9 arranged on the front side of the movable plate 8. A mounting hole 10 is penetrated on the right side of the flip plate 9, and a mounting shaft 11 is overlapped inside the mounting hole 10. Fixed plates 12 are fixedly provided at both ends of the mounting shaft 11. The fixed plate 12 is fixedly installed at a position on the front side of the mounting frame 4. Pulling the movable plate 8 drives the flip plate 9 to rotate on the surface of the mounting shaft 11, so that the movable plate 8 drives the upper fixed magnet 7 and the lower fixed magnet 6 to separate, which is convenient for connecting the movable plate 8 with the mounting frame 4, and avoids the loss of the movable plate 8 and the upper fixed magnet 7 after being taken out.

[0024] Specifically, a drainage assembly is provided on the left side of the detection box 1, and the drainage assembly includes a drainage pipe 18 arranged inside the detection box 1, and a control valve 19 is fixedly installed on the drainage pipe 18. Through the setting of the drainage pipe 18, it is convenient to discharge the turbid water flow in the detection box 1, thereby facilitating the replacement of the water flow in the detection box 1.

[0025] Specifically, an auxiliary support assembly is provided at the bottom of the box cover 3, and the auxiliary assembly includes a support frame 20 provided at the bottom of the box cover 3, and a reinforcing column 21 is fixedly provided inside the support frame 20. Through the setting of the support frame 20, it is convenient to make the mounting frame 4 vertically upward, thereby facilitating the fixing of the packaging bag inside the mounting frame 4.

[0026] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0027] When in use: place the inflated and sealed packaging bag inside the mounting frame 4, so that the side of the packaging bag contacts the lower fixed magnet 6, and place the upper fixed magnet 7 on the packaging bag through the movable plate 8, so that the upper fixed magnet 7 and the lower fixed magnet 6 are adsorbed, and the positions of the two side edges of the packaging bag are fixed by the adsorption of the upper fixed magnet 7 and the lower fixed magnet 6, repeat the above operation, and fix multiple packaging bags inside the mounting frame 4 in turn. After the packaging bag is fixed, pull the box cover 3 to flip through the hinge 2, so that the box cover 3 contacts the top of the detection box 1, so that the box The cover 3 drives the mounting frame 4 to enter the interior of the detection box 1, and the mounting frame 4 drives the packaging bag into the detection box 1 through the mounting plate 5, the lower fixed magnet 6, the upper fixed magnet 7 and the movable plate 8, so that the packaging bag is immersed in water, and the vacuum pump 14 provided in the vacuum assembly is started, so that the exhaust pipe 17 performs vacuum treatment on the detection box 1, so that there is a pressure difference between the detection box 1 and the packaging bag, and the packaging bag is squeezed. During the squeezing process, if bubbles appear on the surface of the packaging bag, it means that the sealing of the packaging bag is poor. If no bubbles appear on the surface of the packaging bag, it means that the sealing of the packaging bag is good.

[0028] To sum up, the packaging bag sealing detection device, through the arrangement of the box cover 3, the mounting frame 4, the mounting plate 5, the lower fixed magnet 6, the upper fixed magnet 7, the movable plate 8 and the vacuum assembly, is convenient for simultaneously detecting the sealing of multiple packaging bags, avoiding the problem that only one packaging bag can be tested for sealing at a time, resulting in a decrease in the packaging bag detection speed, thereby speeding up the packaging bag detection speed, and clamping the side of the packaging bag by the lower fixed magnet 6 and the upper fixed magnet 7 avoids obstruction of the packaging bag surface and causing errors in the detection results, and is used to solve the problems raised in the above-mentioned background technology.
