Technical Field

[0001] The utility model relates to the technical field of folding edges of cake packaging machines, in particular to a folding edge structure of a cake packaging machine. Background Art

[0002] Pastry is a kind of food which is made from one or more of cereals, beans, potatoes, oils, sugar, eggs and other ingredients as the main raw materials, with or without other ingredients, and is made through processes such as preparation, shaping and cooking. After the production of pastries is completed, they need to be packaged in packaging boxes, and in the process of making packaging boxes, the folding structure of the packaging machine needs to be used.

[0003] The folding device is a very important part of the pastry packaging machine. It is used to fold the packaging materials. Usually, a folding mold is used to fold the packaging materials along the predetermined position through a cylinder or other power device. The design and precision of the folding device play a vital role in the packaging effect. Generally speaking, the folding structure of the pastry packaging machine provides complete packaging for the pastries by completing the precise folding of the packaging materials.

[0004] The existing folding structure cannot perform multi-sided continuous folding of the pastry packaging paperboard during the folding process, resulting in low folding efficiency; therefore, a folding structure of a pastry packaging machine is proposed to address the above problem.
