Description

Technical Field

[0001] The utility model belongs to the technical field of packaging machinery, and particularly relates to a frame-shaped pre-folder for a strip carton packaging machine. Background Art

[0002] In the cigarette industry, to meet the diverse needs of consumers for cigarette products and the improvement of quality requirements, multiple specifications and varieties are necessary means to meet consumer needs. The change in the packaging specifications of cigarette sticks directly affects the change in the equipment adjustment size.

[0003] Among them, the YB65A strip carton packaging machine is a commonly used packaging equipment. Its main function is to arrange the small box cigarette packs formed by packaging in a 2*5 (2 layers and 5 columns) arrangement, and complete the strip carton packaging process through a series of folding actions. In the existing technology, the frame-shaped pre-folder is an important part of the YB65A strip carton packaging machine. Its function is to push the strip carton forward and perform a "]" - shaped folding on the strip carton after the cigarette pack and the strip carton paper with glue applied both reach the packaging position of the machine. However, the existing frame-shaped pre-folders are all produced and installed according to the factory settings provided by cigarette manufacturers during factory production, and can only produce products with cigarette pack sizes that meet fixed specification requirements.

[0004] As Figure 1 described, the frame-shaped pre-folder of the strip carton packaging machine in the prior art includes a positioning component I 100 and a positioning component II 200 arranged in parallel. The positioning component II includes a front baffle 201 and a rear baffle 201 fixedly connected. Connecting plates 300 are connected to both the upper and lower ends of the positioning component I 100 and the positioning component II 200 to form a forming bin 300 with a fixed size.

[0005] Due to the differences in the diameters of small box cigarette sticks among different cigarette enterprises, there may be slight differences in the sizes of small box packaging and strip carton packaging. The existing frame-shaped pre-folders mainly have the following problems: First, since its design and installation are completed at the factory, its adaptability is poor and it cannot meet the different needs of different cigarette enterprises for the sizes of cigarette packs. Second, if multiple specifications of frame-shaped pre-folders are prepared, it will increase the spare parts cost of the enterprise, and at the same time increase the labor intensity of repair personnel and the equipment debugging time. Finally, since its design and installation are completed at the factory, if the production demand changes, it is necessary to re-design and install the frame-shaped pre-folder, which undoubtedly increases the production cost and maintenance cost of the enterprise. Summary of the Invention

[0006] To solve the above problems, the present application provides a frame-shaped pre-folder for a strip carton packaging machine, aiming to achieve rapid adjustment of the forming bin to adapt to the production requirements of cigarette packs with different specification sizes.
