The filter stick material pre-folding and collecting device comprises a rack, a paper guide device, a conical barrel, a first-stage forming wheel and a second-stage forming wheel are sequentially installed on the rack from upstream to downstream, a paper guide channel is formed in the paper guide device, and the paper guide channel is gradually shrunk from the inlet end to the outlet end; a conical channel is formed in the conical barrel, the large opening end of the conical channel faces the paper guide device, and the small opening end of the conical channel faces the first-stage forming wheel; the first-stage forming wheel and the second-stage forming wheel are each composed of a fixed wheel and a separation wheel, the distance between the fixed wheels and the separation wheels is the wheel distance, the wheel distance of the first-stage forming wheel is larger than the wheel distance of the second-stage forming wheel, and the diameter of the small opening end of the conical channel is larger than the wheel distance of the first-stage forming wheel. The first-stage forming wheel and the second-stage forming wheel are driven by a power device to rotate. The bundling device can enable the end face hole of the cooling base rod to meet the technological standard, the roundness index meets the technological standard, and the cigarette rejecting amount is reduced by more than 50%.

Laser compound manufacturing rod wire cold shear blade
InactiveCN106119839AReduce removalReduce manufacturing costMetallic material coating processesCobalt based alloyCast iron
The invention mainly solves a rod wire cold shear blade laser manufacturing structure and a manufacturing flow and a method. The gradient cladding is performed for a cobalt base alloy material under a shear blade shear surface stress point, and the cladding quantity of the cobalt base alloy is gradually reduced according to a shear force transfer descending path, so that the blade life is prolonged, and the cost consumption is reduced. In order to reduce deformation generated by laser cladding, the removing quantity of a working layer surface of the laser clad cobalt base material is reduced, so that the blade function is realized, and the manufacturing cost is reduced; and in the shear blade laser cladding process, a shear blade is fixed on a platform manufactured by gray cast iron for dispersing heat and stress generated in the machining process to effectively limit deformation and reduce subsequent machining difficulty.
