It also helps maintain the stable quality of the food itself. Therefore, food needs to be tested for packaging airtightness during the production process.

[0003] Existing food packaging sealing testing devices, while greatly reducing the workload of production by using batch sampling, mostly rely on mechanical equipment for testing. However, mechanical testing makes it inconvenient to distinguish whether food packaging is qualified; furthermore, it is difficult to ensure that each item to be tested is centered during testing, which can easily affect the accuracy of the test.

Therefore, we need to propose a food packaging sealing test device. Utility Model Content

[0005] The purpose of this utility model is to provide a food packaging sealing test device that can improve the ability of the test device to distinguish unqualified products in food packaging sealing tests, further improve the efficiency of the test and distinction, and at the same time ensure that the position of the item to be tested is centered during the test, reducing false detections caused by positional deviation, so as to solve the problems mentioned in the background art.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides: a food packaging sealing test device, including a mounting frame 1, a conveyor belt 2, and a fixed frame 5 installed on the top of the mounting frame 1; a pad 3 for food packaging testing is movably inserted inside the mounting frame 1; an assembly frame 21 is installed at one end of the fixed frame 5, and a sorting component for screening defective products is provided on the surface of the assembly frame 21; a pressure testing component for food packaging sealing testing is movably installed on the top of the fixed frame 5 via an electric push rod 6; a positioning rod 12 is installed on the surface of the fixed frame 5, and a conveying guide plate 13 for guiding the food packaging is movably installed on the surface of the positioning rod 12, and an adjustment component for controlling the unfolding angle of the conveying guide plate 13 is connected to one side of the conveying guide plate 13.

[0022] It is worth noting that the coordinated arrangement of the mounting frame 1, fixing frame 5, conveying guide plate 13, assembly frame 21, sorting component, adjustment component and pressure detection component can improve the detection device's ability to distinguish unqualified products in food packaging sealing tests, further improving the efficiency of detection and differentiation. At the same time, during testing, it ensures that the item to be tested is centered, reducing false detections caused by positional deviation.

[0023] Specifically, the sorting assembly includes: an assembly sleeve 22 connected to the surface of the assembly frame 21, and a limiting rod 23 installed on the inner surface of the assembly frame 21; wherein, a material distribution plate 24 is rotatably connected to the inner wall of the assembly sleeve 22 via a mounting shaft 25, and connecting shafts 26 are connected to both sides of the material distribution plate 24. An electric telescopic rod 27 is movably connected to the surface of the connecting shaft 26, and one end of the electric telescopic rod 27 is hinged to the end of the mounting frame 1.

[0024] The assembly frame 21 is a structure that works with the mounting shaft 25 to install the material distribution plate 24. The material distribution plate 24 is a structure for screening packaged food, which facilitates the differentiation of qualified and unqualified products and facilitates subsequent processing. The connecting shaft 26 is connected to the extended end of the electric telescopic rod 27, which facilitates the control of the material distribution plate 24 by the electric telescopic rod 27. The limiting rod 23 plays a role in limiting the maximum extension angle of the material distribution plate 24 to ensure the effectiveness of receiving items.

[0025] The electric telescopic rod 27 drives the sorting plate 24 to quickly switch angles, achieving rapid separation of defective products. This is 3 times more efficient than traditional manual sorting, and it does not require interruption of the production line for continuous operation.

[0026] The adjustment assembly includes: a connecting rod 14 connected to the surface of the conveyor guide plate 13, and a connecting sleeve 15 movably connected to the surface of the connecting rod 14; wherein, an adjusting screw 16 is threadedly connected to the inner wall of the connecting sleeve 15, an adjusting disc 19 is mounted on the surface of the adjusting screw 16, and a limit block 20 is provided on one side of the adjusting disc 19. A fixed sleeve 17 is rotatably connected to the surface of the limit block 20, a fixed shaft 18 is mounted on the surface of the mounting bracket 1, and the fixed sleeve 17 is movably connected to the surface of the fixed shaft 18.

[0027] In addition, the conveyor guide plate 13 guides and limits the movement of items on the conveyor belt 2, ensuring the items are centered on the conveyor belt 2. The limiting block 20 connects and positions the adjusting screw 16, and the fixing sleeve 17 is a structure that works with the fixing shaft 18 to position the adjusting screw 16. The adjusting assembly uses a screw-sleeve structure, and the unfolding angle of the conveyor guide plate can be adjusted from 30° to 90° by rotating the adjusting disc, adapting to different packaging sizes.

[0028] The pressure detection assembly includes: a connecting plate 7 connected to the extended end of the electric push rod 6, and a limiting guide rod 8 connected to the top of the connecting plate 7; wherein, the bottom of the connecting plate 7 is connected to a detection pressure plate 10 via a pressure sensor 9, and anti-detachment plates 11 are connected to both sides of the bottom of the detection pressure plate 10.

[0029] Furthermore, the electric push rod 6 is a structure for raising and lowering the connecting plate 7, and the limiting guide rod 8 serves as a guide for raising and lowering the connecting plate 7. The pressure sensor 9 uses a model SOP-F1 pressure sensor, and different models of pressure sensors can be replaced as needed. The detection plate 10 is a structure that works with the pad 3 to squeeze the food packaging. During the squeezing process, the pushing force of the electric push rod 6 on the counter-pushing force between the detection plate 10 and the item can be detected in real time by the pressure sensor 9, and the detection data is transmitted to the controller module for computer processing and display. Based on the detected pressure, the working state of the electric telescopic rod 27 is controlled. For example, the pressure index of a qualified product is 3, less than 3 is an unqualified product, and vice versa.

[0030] By detecting the double-sided anti-slip plate 11 structure of the pressure plate 10, the packaging is effectively prevented from slipping under pressure. It is especially suitable for vacuum packaging bags with smooth surfaces. The integrated electric push rod, pressure sensor and anti-slip plate realize automated pressure detection, accurately quantify the sealing pressure value, avoid the subjective error of manual detection, and the adjustable conveyor guide plate and positioning rod work together to ensure that the packaging is accurately aligned at the detection position and reduce false detection caused by positional deviation.

[0031] Preferably, the mounting bracket 1 has a through groove on its side to accommodate the mounting pad 3, and a fixing member 4 is installed on the side of the mounting bracket 1 to fix the position of the pad 3. The fixing member 4 is a structure for installing and fixing the pad 3. The pad 3 is designed to be removable and can be inserted into the side fixing member 4, which facilitates quick replacement of pads 3 of different thicknesses.

[0032] According to the size of the packaged food, the adjusting screw 16 can be rotated by the adjusting plate 19, so that the connecting sleeve 15 connected to the conveyor guide plate 13 at the end can move, so that the conveyor guide plate 13 can be expanded or retracted along the positioning rod 12, thereby cooperating with the conveyor belt 2 to transport the packaged food, ensuring the centering of the packaging, and facilitating the electric push rod 6 to push the detection pressure plate 10 equipped with pressure sensor 9 downward to squeeze the packaged food for detection, ensuring the accuracy of the detection. After the detection is completed, according to the pressure data of the squeeze detection, the controller controls the electric telescopic rod 27 to extend or retract. If the product is unqualified, the electric telescopic rod 27 is retracted, which rotates the connecting material distribution plate 24 along the mounting shaft 25, and guides the bottom of the material distribution plate 24 into the unqualified collection box 28, so as to achieve the effect of rapid separation.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
