Description

Technical Field

[0001] The invention belongs to the technical field of cigarette packaging, and in particular relates to a quick disassembly and assembly device for a fixed shaft of a cigarette baffle of a packaging machine. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The packing machine has one baffle plate inside and one outside, which are used to assist in the transportation of cigarette strips. Due to the contact with the two sides of the two cigarette strips, glue and glue scale will appear on the baffle surface, causing quality defects such as folding and flanging of the side of the strip box or scratches on the end of the strip box. When the cigarette is squeezed out, the baffle plate will be squeezed and deformed, requiring regular maintenance. Since the internal baffle plate is on the inside of the machine, it is difficult to disassemble and take out due to space limitations. During maintenance, the entire external strip box forming wheel device must be disassembled first, and then the baffle plate maintenance must be performed. If the baffle plate needs to be replaced, the baffle plate fixing shaft must also be disassembled.

[0004] In actual operation, there are the following problems: First, maintenance is inconvenient, because the entire external box forming wheel device needs to be disassembled, which is heavy and requires two people to complete, increasing the labor intensity of the maintenance workers and posing safety hazards. Second, maintenance is time-consuming, and it is necessary to disassemble the box forming wheel device first, maintain the cigarette baffle, or disassemble the baffle fixing shaft to replace the baffle, and then reinstall it. The steps are cumbersome and time-consuming, affecting the operating efficiency of the equipment. Summary of the invention
