Description

Technical Field

[0002] Food refers to all kinds of finished products and raw materials for human consumption or drinking, as well as items that are both food and Chinese medicinal materials according to tradition. At the same time, food can be subdivided into snack foods and formal meals. In particular, packaged food requires high sealing. Food packaging is one of the main projects in the food industry process. It protects food and prevents it from being damaged by biological, chemical, and physical external factors during the circulation process from leaving the factory to the hands of consumers. It can also have the function of maintaining the stable quality of the food itself. It facilitates the consumption of food. In order to check the sealing of food packaging, it is necessary to use a food packaging sealing detection device for inspection and processing. Sealed packaging prevents food from being affected by external factors during the circulation process from leaving the factory to consumers, effectively prevents moisture and isolates it from the air, and prevents the inside of the food packaging bag from being affected by moisture and oxygen in the air and deteriorating.

[0003] A food packaging sealing detection device disclosed in the Chinese utility model patent application publication specification CN217466144U solves the problem of many operating steps, but the food packaging sealing detection device still has the following disadvantages: First, when the above-mentioned food packaging sealing detection device is detecting, because the spring elastic force is not fixed, the force exerted by the extrusion block on the pressure sensor is different, resulting in inaccurate data and low detection accuracy; Second, when the above-mentioned food packaging sealing detection device is detecting, it can only detect one by one, the detection efficiency is relatively slow, and it is not conducive to use.

[0029] Embodiment 2:

[0030] See also Figures 1 to 6The utility model provides a technical solution: a food packaging sealing detection device, the top of the base 1 is fixedly connected with a second electric telescopic rod 24 and a third electric telescopic rod 29, the second electric telescopic rod 24 is a multi-section electric telescopic rod, there are two second electric telescopic rods 24, the second electric telescopic rod 24 is located on the back of the water tank 2, the telescopic end of the second electric telescopic rod 24 is fixedly connected with a first fixed plate 25, the bottom of the first fixed plate 25 is fixedly connected with a fixed rod 26, there are four fixed rods 26, all of which are located above the first conveyor belt 7, the bottom of the fixed rod 26 is fixedly connected with a pressing plate 27, the pressing plate 27 is a metal mesh, the size of the pressing plate 27 is consistent with the first conveyor belt 7, the pressing plate 27 and the first conveyor belt 7 are in the same longitudinal direction, the fixing rods 26 are evenly distributed at the four corners of the pressing plate 27, and a card slot 28 is provided at the bottom of the pressing plate 27, the shape and size of the card slot 28 , and their lengths are consistent with the dividing belt 35. There are two third electric telescopic rods 29, which are located on the back of the third conveyor belt 21. The top of the third electric telescopic rod 29 is fixedly connected with a second fixed plate 30, which is located above the third conveyor belt 21. The bottom of the second fixed plate 30 is fixedly connected with absorbent cotton 31, which is made of sponge. A groove is provided at the bottom of the absorbent cotton 31, and the size of the groove is consistent with that of the food packaging. The absorbent cotton 31 is located directly above the third conveyor belt 21, and the height of the absorbent cotton 31 is greater than the dividing belt 35. A connecting rod 32 is fixedly connected to the bottom of the base 1. There are four connecting rods 32, which are evenly distributed at the four corners of the bottom of the base 1. The bottom of the connecting rod 32 is rotatably connected with a universal wheel seat 33, and a rotating groove is provided at the bottom of the universal wheel seat 33, and a universal wheel 34 is rotatably connected to the inner wall of the rotating groove.

[0031] When in use, the existing food packaging sealing detection device is performing detection, because the spring elastic force is not fixed, which will cause the force exerted by the extrusion block on the pressure sensor to be different, resulting in inaccurate data and low detection accuracy. Therefore, there is a food packaging sealing detection device. When the food package flows to the right side of the first conveyor belt 7 to wait for the sealing detection, the telescopic end of the second electric telescopic rod 24 contracts, driving the first fixed plate 25 and the pressing plate 27 to move downward. When the pressing plate 27 presses on the top of the food package, the telescopic end of the second electric telescopic rod 24 stops contracting. At this time, The telescopic ends of the first electric telescopic rod 3 and the second electric telescopic rod 24 begin to contract at the same frequency, so that the food package remains motionless on the top of the first conveyor belt 7. When the food package enters the water, the telescopic end of the first electric telescopic rod 3 stops contracting, and the telescopic end of the second electric telescopic rod 24 continues to contract, increasing the pressure on the food package. Then, the telescopic end of the second electric telescopic rod 24 stops contracting, and the specific food package with poor sealing is observed by setting the pressure plate 27 as a metal mesh. When the inspection is completed, the second electric telescopic rod 24 and the telescopic end of the first electric telescopic rod 3 are extended to restore The food packages that are not tightly sealed are manually picked out. Then, when the food packages that have been tested flow to the right end of the third conveyor belt 21, the water stains on the outside of the food packages are cleaned. The telescopic end of the third electric telescopic rod 29 is retracted, and the second fixed plate 30 drives the absorbent cotton 31 to slowly fall downward. Because the groove at the bottom of the absorbent cotton 31 is the same size as the food package, the absorbent cotton 31 will completely wrap the food package when it falls. Through the characteristics of the absorbent cotton 31 sponge, the water stains on the surface of the food package are absorbed, thereby completing the sealing test, and the bottom of the fixed rod 26 is fixed A pressure plate 27 is connected, and the pressure plate 27 is a metal mesh setting, so that the food packaging sealing detection device can ensure the consistency of size when detecting food packaging and ensure the accuracy of data. Through the coordinated setting of the pressure plate 27 and the first conveyor belt 7, during use, the food packaging can be measured to see whether the packaging is sealed after entering underwater. The setting of the pressure plate 27 as a metal mesh can make the inspector clearly see which food packaging is not tightly sealed, thereby achieving the effect of ensuring the consistency of size when detecting food packaging and achieving the purpose of ensuring the accuracy of data.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
