Abstract
The present invention is a kind of pile-cutting method of fine pinwale corduroy.Adopt common in, thick, slice clipping method, ULTRAFINE CORDUROY is carried out clipping production, can produce that to cut damage many, fine hair is bad, bouncing pilotage rate height, shortcoming such as cost rate is low.The invention is characterized in diameter be the guide pin (7) of 0.5～0.6 millimeter steel wire insert fabric radially suede do to be inserted mode at interval, it is 26～29 degree that the central vertical line of cutter shaft (2) of circular knife and this cutter shaft center to the angle (10) of the line of cutpoint (5) is housed, it is few that the present invention has the damage of cutting, the fine hair quality is good, the bouncing pilotage rate is low, can produce low cost and other advantages in batches.
Description
The present invention relates to a kind of pile-cutting method of fine pinwale corduroy.
The clipping of corduroy is a technology very important together in the corduroy production process, generally all carries out on cutting machines.The critical component of cutting machines is clipping cutter shafts, tightens solid matter at its cutter shaft and is being listed as garden blade and guide pin.During clipping, every garden blade is sandwiched in the middle of the slit of a guide pin, and every guide pin inserts the radially suede lane of fabric, and fabric relatively moves to the guide pin direction by the feeding card clothing roller, by closely being arranged in the garden blade that is rotating on the cutter shaft the floating weft yarn in the fabric is severed, become fine hair.Usually the clipping guide pin front end fineness of usefulness is more than 0.30 millimeter, the central vertical line of cutter shaft (2) and this cutter shaft center are that the angle (10) of the line of cutpoint (5) is spent 22～32 to knife plate (3) corner angle, scope is bigger, and guide pin inserts all radially suede lane, a clipping.This method is that the carse, medium and small kind below 18 has good effect in 2.5 centimetres for the specification of corduroy fabric.But, during for 2.5 centimetres of ULTRAFINE CORDUROY grey cloth clippings more than 20,, will produce and seriously cut damage if adopt common clipping method, cut loss rate about 35%.Bouncing pilotage rate height, greater than 150 times/hundred meters, the fine hair fraction defective is about 40%, and the quality of ULTRAFINE CORDUROY is descended, and yield rate is low, and substandard cloth increases, cost height, problem such as yielding poorly does not form batch process, and production efficiency is low.
The objective of the invention is to overcome the above-mentioned shortcoming that produces, a kind of clipping method is provided, what produce in the time of controlling the ULTRAFINE CORDUROY clipping effectively seriously cuts damage, and fine hair is bad, the phenomenon that the bouncing pilotage rate is high.
The invention provides a kind of pile-cutting method of fine pinwale corduroy, it is characterized in that guide pin (7) with the steel wire of 0.5～0.6 millimeter of diameter, in these guide pin front end 50 mm lengths, its steel wire fineness from the termination is 0.20～0.30 millimeter, and to carry out the transition to 50 millimeters gradually be 0.50～0.60 millimeter, this guide pin inserted radially suede do to be inserted mode at interval.Because it is very narrow that the radially suede of special slice is done, if the steel wire fineness of guide pin during greater than above-mentioned size clipping, the very big easy bouncing pilotage of propelling resistance.And less than above-mentioned size, the rigidity of guide pin is affected, the easy flexural deformation of guide pin.To the requirement of guide pin be bend to 50 indeformable when spending.Owing to be the ULTRAFINE CORDUROY grey cloth, if guide pin insert every radially the clipping in suede lane finish, then will produce the fine hair bad phenomenon.So guide pin insert fabric radially suede do to adopt inserted mode at interval, its mode can be every one radially suede do to insert a guide pin, also can every 2 radially suede do to insert a guide pin or every 3 radially suede do to insert a guide pin.It is 26～29 degree that the central vertical line of cutter shaft (2) of garden blade and this cutter shaft center to the angle (10) of the line of cutpoint (5) is housed during clipping.The runout tolerance of cutter shaft is within ± 0.025 millimeter.Because radially suede does narrow, the thickness of garden blade is 0.18～0.20 millimeter, and the edge of a knife angle of blade is 55 ± 5 degree, undermines serious fine hair bad phenomenon otherwise can produce to cut.Advantage of the present invention is to cut to decrease to lack, and the fine hair bad phenomenon is few, and the bouncing pilotage rate is low, ULTRAFINE CORDUROY cloth percentage of A-class goods height, and the productivity ratio height can form batch process, and production cost is low.
Accompanying drawing: clipping method principle schematic.
(1) clipping garden blade wherein, (2) cutter shaft, (3) knife plate, (4) clipping platform, (5) cutpoint, (6) put needle plate, (7) guide pin, (8) suede base, (9) pushing needle bar, (10) angle.
Embodiment 1:
With the door width of cloth is 114 centimetres of ULTRAFINE CORDUROY grey cloths (22/2.5 centimetre), be placed on the baking machine, do baking and handle, and reach the requirement of the receipts width of cloth, then, cutting machines on the grey cloth, be the guide pin (7) of 0.6 millimeter steel wire with diameter at first, in these guide pin front end 50 mm lengths, its fineness is 0.30 millimeter by the termination, and to transit to 50 millimeters places gradually be 0.60 millimeter, with this guide pin insert grey cloth radially suede do, inserted mode be every one radially suede do guide pin of insertion.The suede grey cloth is transmitted by the feeding card clothing roller and the guide pin direction relatively moves.Suede grey cloth fltting speed is 7.4 meters/minute.The clipping garden blade (1) of rotation is slit into fine hair to the floating weft yarn on the suede grey cloth, and the thickness of blade is 0.20 millimeter, and edge of a knife angle is 60 degree.Cutter shaft during clipping (2) central vertical line and this cutter shaft center to the angle (10) of the line of cutpoint (5) is 26 degree, after having cut half suede that does not cut is as yet done to insert guide pin again, carries out a clipping again and becomes finished product.It cuts loss rate and is lower than 0.6%, and fine hair is bad to be lower than 0.4%, and the bouncing pilotage rate is lower than 45 times/hundred meters.
Embodiment 2:
Cutter shaft central vertical line and this cutter shaft center to the angle of the line of cutpoint is 29 degree among the change embodiment 1, with diameter is the guide pin (7) of 0.5 millimeter steel wire, in these guide pin front end 50 mm lengths, its fineness is 0.20 millimeter by the termination, and to carry out the transition to 50 millimeters gradually be 0.50 millimeter, and the thickness of garden blade is got 0.18 millimeter, edge of a knife angle 50 degree, other conditions are constant, and carry out clipping, and it cuts loss rate and is lower than 0.4%, and the fine hair fraction defective is lower than 0.8%.The bouncing pilotage rate is lower than 62 times/hundred meters.
Claims (4)
