Description

Technical Field

[0001] This utility model relates to the field of food packaging testing technology, specifically a device for testing the sealing performance of food packaging. Background Technology

[0002] Food refers to all kinds of finished products and raw materials for human consumption or drinking, as well as items that are traditionally both food and Chinese medicine. Food can also be further subdivided into snack foods and formal meals. Packaged food, in particular, requires a high degree of airtightness.

[0003] Authorization announcement number CCN220092193U discloses a food packaging sealing test device. This patented technology uses an electric telescopic rod to push a pressure plate downward and squeeze the food packaging. If the pressure plate cannot be stopped, it indicates that the food packaging has good sealing performance. If the pressure continues downward and contacts the air bladder, it indicates that the packaging has poor sealing performance. When the pressure plate stops squeezing the food packaging, the actuating plate can rotate under the elastic force of the torsion spring and push the food packaging onto the sliding plate. The sliding plate then collects the substandard food packaging. However, this solution only uses a simple pressing method to test the sealing performance of the food packaging. This method may not produce a noticeable difference when pressing on small holes or poorly sealed areas. The pressing test cannot provide specific quantitative data to assess the degree of leakage. The pressing test can only perform static testing of the packaging at a certain moment and cannot monitor the changes in sealing performance of the packaging in real time during storage and transportation. Therefore, a food packaging sealing test device is needed to improve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0027] A food packaging sealing test device includes a main body 1, a pressure regulating component 2 is disposed inside the main body 1, and a control component 3 is fixedly connected to the top of the main body 1.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the main body 1 includes a housing 101, with a pressure sensor 103 fixedly connected inside the housing 101. A detection chamber 104 is provided inside the housing 101. The pressure regulating component 2 includes a base 201, with a pressure pump 202 installed on the top of the base 201. A pipe 203 is fixedly connected to the output end of the pressure pump 202. The control component 3 includes a top box 301, with a controller 305 fixedly connected to the side of the top box 301. The controller 305 is equipped with a data processing module, an alarm module, and a pressure data transmission module. Using the pressure sensor 103 and the pressure pump 202, the detection chamber 104 can be pressurized or depressurized according to a preset pressure change curve. The data processing module, alarm module, and pressure data transmission module analyze the slope of the pressure change curve and the pressure stabilization time to determine the sealing performance of the food packaging. This allows for precise control of pressure changes and real-time monitoring of pressure data, enabling accurate detection of even minute leaks.

[0029] The tube 203 extends into the detection chamber 104. A valve 204 is installed at the bottom of the tube 203. The data processing module, alarm module, and pressure data transmission module are electrically connected. A support rod 303 is fixedly connected to the top of the top box 301, and an alarm 304 is fixedly connected to the top of the support rod 303. A display screen 306 is fixedly connected to the side of the controller 305. Physical buttons 307 and switches 308 are installed on the side of the top box 301. A heat dissipation grille 302 is installed on the side of the top box 301. A chamber door 105 is installed on the side of the box 101. The display screen 306 and the alarm 304 can be used to display the detection results and emit an audible and visual alarm signal when a leak is detected. The detection results can be displayed in real time, and an alarm is triggered immediately when a leak is detected, facilitating timely handling of problematic packaging. This device has the advantages of high precision, high degree of automation, real-time feedback, and wide applicability, which can effectively improve the efficiency and reliability of food packaging quality control.

[0030] In this embodiment, as Figure 1 As shown, an observation window 106 is provided inside the cavity door 105. A transparent acrylic plate is installed inside the observation window 106. A handle 107 is fixedly connected to the side of the cavity door 105. A pad 102 is fixedly connected to the bottom of the box 101. Four pads 102 are provided. The transparent acrylic plate installed inside the observation window 106 not only provides a clear and bright visual effect, but also improves the impact resistance of the observation window 106.

[0031] The working process of this utility model is as follows: When the food packaging sealing test device designed in this scheme is working, the food packaging to be tested is placed in the test chamber 104, and the chamber door 105 is closed to ensure that the test chamber 104 is completely sealed from the outside. The pressure sensor 103 and the pressure pump 202 pressurize the test chamber 104 according to the preset pressure change curve. At the same time, the pressure sensor 103 monitors the pressure change in the chamber in real time and transmits the data to the data processing module, the alarm module, and the pressure data transmission module. The slope of the pressure change curve and the pressure stabilization time can be analyzed. If the pressure change curve fails to reach a stable state within the predetermined time, or if the pressure change slope is abnormal, it is determined that the packaging is leaking and the alarm 304 is triggered. After the test is completed, the chamber door 105 is opened and the food packaging is taken out. If the test result shows that the sealing is good, the packaging can proceed to the next process. If the test result shows that the leakage is occurring, the packaging needs to be reprocessed or scrapped.
