Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cigarette production equipment, in particular to a material rod slitting device with air blowing ejection function and a method thereof. BACKGROUND

[0002] In the granular heating non-combustible cigarette filling process, raw material rods such as filter rods, paper tubes, and solid components need to be slitted to form fixed-length rod segments, which are then conveyed to the downstream machine for filling by the ejection device. The ejector rod is generally a solid round rod, and hard contact occurs between the ejector rod and the slitted rod segment during the ejection process. If there is any blockage in the channel, the ejector rod will squeeze and deform the rod segment, causing frequent shutdown.

[0003] After the material rod is slitted, it is pushed by the ejector rod into the rear channel, where one segment is arranged next to another. If the strength of the rod segment is not enough, such as the filter rod, it will be squeezed and even turned over to block the channel during the queuing and pushing process in the channel hose to the downstream. Since the queued rod segments are pushed out by the ejector rod, there will be residual rod segments that have not been pushed out in the channel during the later production, causing waste. SUMMARY

[0004] In view of the deficiencies in the prior art, the present application provides a material rod slitting device with air blowing ejection function and a method thereof. The slitted rod segments are ejected by air blowing to achieve hard contact between the ejector rod and the slitted rod segment during the ejection process, and to avoid residual and waste of the rod segments.
