Description

Technical Field

[0001] The utility model relates to the technical field of degradable lunch boxes, in particular to a metal foreign body detection device for a degradable lunch box transmission line. Background Art

[0002] Degradable lunch boxes refer to those that can be decomposed by microorganisms in the natural environment. They are usually made of biodegradable materials, such as corn starch, polylactic acid, cellulose, etc. These materials can be decomposed into water, carbon dioxide and biomass by bacteria, fungi and other microorganisms in nature under certain conditions, thereby reducing pollution to the environment. There are currently a variety of degradable lunch boxes available on the market, such as biodegradable plastic lunch boxes made from whole corn flour, CO2 resin and EVA. This type of lunch box shows good performance in terms of cost, processing environment, mechanical properties and degradation properties. In the production process of degradable lunch boxes, in order to ensure that there are no other metal impurities inside the lunch boxes, they need to be tested and processed, and there are still some problems with the existing detection devices when used:

[0003] 1. Unloading is cumbersome. In the production process of existing degradable lunch boxes, in order to conduct safety inspections on the degradable lunch boxes to avoid the contamination of metal foreign matter, the existing detection device cannot quickly remove the lunch boxes after detecting the lunch boxes containing metal foreign matter, and needs to be transported for a distance. Such transportation will cause confusion when manually taking the lunch boxes, resulting in poor use of the detection device.

[0004] 2. Low degree of automation. In the process of metal foreign body detection of existing biodegradable lunch boxes, the metal foreign body can only be picked up manually after the detection is completed. However, such a picking method will cause certain fatigue to the workers during long-term work on the assembly line, and the speed will not be able to keep up with the speed of the conveyor belt, which will lead to omissions.

The overall degree of automation is high, and accurate work can be performed for a long time.

[0027] A first magnet 7 is bonded to one side of the end of the fixing plate 5, and a second magnet 8 is provided on one side outer wall of the metal detector 3, the first magnet 7 and the second magnet 8 have opposite magnetic properties, a piston tube 14 is fixed to the bottom outer wall of the guide slider 12 by bolts, and a piston rod 15 is slidably inserted into the inner wall of the piston tube 14, and a connecting air pipe 16 is connected to the inner wall of one side of the bottom of the piston tube 14;
