Description

Technical Field

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

[0002] Puffed food is made of cereals, potatoes, beans and other foods with low water content as the main raw materials. After being pressurized and heated, the volume of the raw materials themselves expands, and the internal structure also changes. After processing and molding, these foods are made. Because the structure of these foods is porous and fluffy, the taste is crispy and sweet, and they have certain nutritional value, they are very popular among people. In order to prevent puffed foods from being squeezed and broken, and the oils and fats of the products from being oxidized and rancid, nitrogen is often filled into the packaging bags. Once the puffed food packaging bags are not sealed, nitrogen leaks during use and transportation, and the puffed food will easily change its taste and become inedible.

[0003] Typically, air leaks in bagged puffed foods occur at the seals at both ends. Because the seals are not tight and the seal lines are incomplete, nitrogen leaks are caused. The food sealing detection device in the prior art usually stops and then presses to detect whether there is a leak. However, the process of stopping and pressing takes a lot of time, resulting in low detection efficiency. Utility Model Content

[0032] like Figure 1-3As shown in the figure, it is an embodiment of a puffed food packaging sealing detection device provided by the utility model. In this embodiment, it includes a transmission workbench 10, wherein the transmission workbench 10 includes a transmission platform 11 and a detection operation device, the transmission platform 11 includes a transmission belt 12 and a control host 13, and a stop baffle 14 is arranged on the transmission belt 12 at intervals.

[0033] Among them, since the nitrogen filled in the bagged puffed food will cause the surrounding environment temperature to drop if it leaks, therefore, when in use, the bagged puffed food placed at intervals on the transmission belt 12 is rolled by the roller 17 in turn, and the bagged puffed food with leakage will reduce the temperature around the leakage hole. The bagged puffed food with leakage is detected by the thermal imaging sensor 19, and a control signal is sent to the sensor 24 through the connected controller. After the sensor 24 senses the position of the stop baffle 14 at the end of the bagged puffed food with leakage detected after rolling, the stepper motor 20 drives the rotating push rod 21 to push the bagged puffed food with leakage to the slide 22 and fall into the receiving box 23.

[0034] Among them, in the above technical solution, the roller 17 includes a roller bracket 26, and the top end of the roller bracket 26 is fixedly connected to the telescopic end of the electric telescopic rod 18.

[0035] Furthermore, in the above technical solution, the roller 17 also includes a group of first rollers 27 and two groups of second rollers 28. The first rollers 27 are arranged at the bottom of the rolling bracket 26, and both ends of the first rollers 27 are rotatably connected to the rolling bracket 26 through a coupling seat.

[0046] Among them, the heating layer 31 includes a heating wire and a temperature sensor. When in use, the surface of the transmission belt 12 is heated by the heating wire, and the temperature is kept constant by connecting the temperature sensor to maintain the heating temperature set by the control host 13, thereby establishing a temperature that is different from that of the bagged puffed food, making it convenient for the thermal imaging sensor 19 to inspect the leaking bagged puffed food.
