TECHNICAL FIELD
[0001] The utility model belongs to the technical field of vibration cutter cutting, more specifically, relates to a vibration cutter cutting mechanism and carton forming machine. BACKGROUND
[0002] In the process of making cartons in a carton factory, in addition to cutting the paperboard by using a cross cutter and a longitudinal cutter, it is often necessary to cut long circular handle holes or circular air holes on the paperboard. The handle holes facilitate the transfer and handling of the cartons by the operators, and the air holes facilitate the mutual communication between the fresh food and the external environment, have a good air permeability, and ensure the quality of the food.
[0003] When cutting the special-shaped holes of the cartons, a vibration cutter is usually used. The cutting of the special-shaped holes in the transverse direction is realized by the transverse movement of the vibration cutter. In combination with the longitudinal conveying effect of the supporting roller on the paperboard, the effective cutting of various special-shaped holes on the paperboard can be realized. Since the thicknesses of the paperboards of different specifications of cartons are different, the height of the vibration cutter needs to be adjusted when different specifications of cartons are replaced. Due to the influence of the vibration of the vibration cutter, the traditional fixing mode is prone to cause the unstable installation of the vibration cutter, thus causing the large variation of the cutting depth of the vibration cutter. When the cutting is too deep, the vibration cutter is prone to interfere with and collide with the lower supporting plate, and when the cutting is too shallow, the cutting is not transparent, which affects the removal of the paperboard in the subsequent hollowed-out area.
