Description

TECHNICAL FIELD

[0001] The utility model relates to tobacco machinery technical field, concretely relates to a positioning device for cigarette inner frame paper disc cutter. BACKGROUND

[0002] The inner frame paper disc cutter is a consumable part, which needs to be replaced regularly. After replacement, it needs to be debugged to ensure that the distance between the two blades is a certain value. However, since the cross section of the inner frame paper disc cutter is triangular, the ordinary vernier caliper cannot accurately measure it. Moreover, once the inner frame paper conveying and cutting assembly is installed on the machine, the transverse space of the inner frame paper disc cutter becomes narrow, which makes it impossible for the vernier caliper to measure. The maintenance personnel can only rely on their feelings to adjust it. Then, the two dotted lines of the cut-to-length inner frame paper are measured, and it often needs to be adjusted repeatedly several times. Even if the distance between the two blades of the disc cutter can be adjusted to the appropriate value, it cannot guarantee that the distance between the two cutting lines and the paper edge size is consistent, thereby causing quality problems such as uneven box seam and loose box cover.

[0003] A positioning device for positioning a workpiece to be processed is disclosed in Chinese Patent No. CN110860924B, which was granted on November 16, 2021. The positioning device includes a positioning seat, a limiting piece, and a clamping piece. The positioning seat has a positioning surface for placing the workpiece to be processed. The limiting piece protrudes from the positioning surface and is in limiting contact with the workpiece to be processed along a first direction. At least two clamping pieces are arranged on the positioning surface and located on the same side of the limiting piece. The at least two clamping pieces are distributed on both sides of the workpiece to be processed along a second direction intersecting the first direction. The clamping pieces on both sides are configured to be able to open or close under the action of an external force. Each side clamping piece forms a clamping surface facing the clamping piece on the other side. The clamping surfaces on both sides and the positioning surface located therebetween collectively form a clamping position for clamping the workpiece to be processed. The size of the clamping position in a third direction intersecting the first direction and the second direction gradually decreases. Although the above-mentioned patent is for positioning the workpiece to be processed, it is not suitable for positioning and clamping the tobacco machinery, and its application range is limited.
