Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a carton cover folding machine. Background Art

[0002] The carton folding machine is a kind of equipment that automatically folds and seals cars. It can reduce the labor intensity of workers and improve production efficiency. It is widely used. At the end of the assembly line, a carton folding machine is installed to seal and pack products for easy storage and transportation. After the carton is packed with items, you only need to put the packed carton into the folding machine, and then drive the conveyor belts on both sides to transport it under the folding device. The carton folding device on the folding machine is started, and the carton is automatically folded. The folding and sealing are completed at one time without manual operation. The working principle of the automatic folding machine is to automatically fold the four upper covers of the carton and automatically seal it with tape.

[0003] However, there are some problems with the existing carton folding machines. When the carton is moving towards the folding device, the short cover is first folded by the pressing plate and the folding plate, and then the long cover is folded by the folding rod. However, there are certain problems with the existing carton folding machines. When the short cover is located inside the long cover, the cover can be folded normally because the short cover must be folded first. However, when the short cover is located outside the long cover, the long cover will block the short cover when folding it. The folding machine cannot fold the carton normally, resulting in the inability to seal the carton normally. Workers are required to manually adjust the positions of the short cover and the long cover before they can fold and seal the carton normally. To this end, we provide a carton folding machine to solve the above problems. Utility Model Content
