Description

Technical Field

[0001] The invention relates to a composite cigarette filter automatic assembly machine, belonging to the field of mechanical equipment. Background Art

[0002] Most of the production equipment for composite cigarette filters adopts the direct current production line, so a workpiece needs to be repeatedly clamped and placed several times.

Therefore, it is necessary to develop a different production line equipment that can both ensure the yield and improve production efficiency. Summary of the invention

Then the rotating table 24 continues to rotate (at this time, one-third of the exposed filter disc passes through the filter disc pressing mechanism 42, and the filter disc pressing mechanism 42 presses the filter disc to a certain angle to ensure that the first filter disc compacting mechanism 401 can press the filter disc flat into the outer tube in the next step) to the first filter disc compacting mechanism 401. After the filter disc is pressed in, the rotating table 24 continues to rotate to the inner tube installation mechanism 5, and the inner tube installation mechanism 5 clamps the inner tube and sends it into the outer tube. The rotating table 24 continues to rotate to the inner tube compacting mechanism 501, and the inner tube compacting mechanism 501 presses the inner tube to accurately place it into the outer tube. The rotating table 24 continues to rotate to the combined compacting mechanism 6.

[0049] The composite cigarette filter automatic assembly machine of the present invention replaces the linear assembly line with a frustum-type workstation distribution, eliminating the workstation changing and clamping action in the production process, which not only improves the yield but also increases the output.
