The tire tread shield separation cutting machine that a kind of tyre surface coincideing property of otch is good
Technical field
The present invention relates to the tire tread shield separation cutting machine that a kind of tyre surface coincideing property of otch is good.
Background technology
The production process of tire is: dispensing-mixing-extrusion tyre surface-molding-sulfuration-product inspection-packaging is dispatched from the factory.After tyre surface is forced out, at one layer of shield of lower section pad of tyre surface, so it is post-rolled on tyre surface roller the molding procedure entering next step.
When molding, needing first tyre surface and shield to be separated, tyre surface carries on a conveyor, when the tyre surface of process is in the length of regulation, uses cutting knife to cut.
The tire tread shield separation cutting machine that tyre surface coincideing property of otch is good, including frame 10, belt conveyor 1, cutter sweep 2, tyre surface roller 3 and tyre surface roll stand 4, described belt conveyor 1 is arranged on frame 10 upper end, described cutter sweep 2 is arranged on above belt conveyor 1, the top of described belt conveyor 1 is additionally provided with infrared heating device 9 near end, tyre surface on tyre surface roller and shield are after carry-over pinch rolls traction separates, tyre surface enters belt conveyor, completes corresponding cutting action on belt conveyor.At present, cutter sweep includes left standing frame, right standing frame and cutting knife, and cutter sweep is fixed on the upper end of the left and right sides of frame 10 by left standing frame and right standing frame.At present, cutting knife is all vertically arranged, and the otch at tyre surface two ends is vertical otch, and when tire building, the identical property of both sides otch is poor, ultimately results in the second-rate of tire, poor-performing.
Additionally current, in course of conveying, neither one compresses the device of tyre surface, and so when cutting, tyre surface easily deviates delivery track.Or compress only with a roller, operationally, roller can not adjust position the most up and down, and operational reliability is poor.
Summary of the invention
For existing problem, it is an object of the invention to provide the tire tread shield separation cutting machine that a kind of tyre surface coincideing property of otch is good so that the otch of tyre surface is bevel cuts, during tire building, the identical property of both sides otch is fine, and tyre surface is reliable.
To achieve these goals, the technical scheme is that the tire tread shield separation cutting machine that a kind of tyre surface coincideing property of otch is good, including frame, belt conveyor, cutter sweep, tyre surface roller and tyre surface roll stand, described belt conveyor is arranged on frame upper end, described cutter sweep is arranged on above belt conveyor, the top of described belt conveyor is additionally provided with infrared heating device near end, it is characterized in that: in described frame, be provided with the conveying roller that a row is parallel with belt conveyor, described conveying roller is positioned at the lower section that belt conveyor is anterior, the frame of the lower section of this row's conveying roller is provided with shield winding roller, the front side of described frame is provided with one group of carry-over pinch rolls, described tyre surface roll stand is positioned at the frame of belt conveyor lower rear, described tyre surface roller is contained in tyre surface roll stand;
nullDescribed cutter sweep includes left standing frame、Right standing frame、Cutting knife and by a left side、Right plate and front、The rectangular frame that back side panel surrounds,A left side for described rectangular frame、Right plate downwardly extends,A left side at rectangular frame、On the extension of right plate, the lower end against rectangular frame is provided with chute,Described chute is along left、The width of the extension of right plate is arranged,Described rectangular frame is left by it、Before right plate, after height, low dip is fixed on left standing frame and right standing frame,It is left that the left and right sides of described cutting knife inserts rectangular frame respectively、In chute on right plate extension,The middle part of the upper surface of described cutting knife is provided with cylinder and connects seat,Described cylinder connects seat and stretches out rectangular frame from rectangular frame center,Cutting knife cylinder is had in rectangular frame installed in front,It is connected that the piston rod of described cutting knife cylinder is connected seat through the front side board of rectangular frame with the cylinder on cutting knife;
The initiating terminal of described belt conveyor be also arranged above hold-down mechanism, this hold-down mechanism is positioned at cutter sweep front and against cutter sweep, described hold-down mechanism includes by left column, right column and the portal of entablature composition, wherein left column, right column is separately fixed at the upper end of frame left and right sides, a left side at portal, middle cross bar it is provided with between right column, at least one roller mounting bracket is installed on the leading flank of wherein said entablature, roller is arranged in roller mounting bracket, it is set with swing arm on wherein the middle cross bar, described swing arm is positioned at the rear of portal, one end of described swing arm is provided with radial direction through hole, swing arm is sleeved on middle cross bar by this radial direction through hole, the other end fixed installation pulley of described swing arm, on described pulley, linear transducer is installed.
Using such scheme, tyre surface and shield on tyre surface roller are wound on shield winding drum automatically at the conveying roller below frame, shield, and tyre surface enters belt conveyor, horizontal feed on belt conveyor after the carry-over pinch rolls of frame side.
Tyre surface is through out-of-date, and in front end by the pressuring action of roller, frictional resistance is little, and tyre surface can well realize being carried.The most in the wings, swing arm is close with cutter sweep.When a length of setting value of process, cutting knife brings into operation and cuts.Cutting when, swing arm can adjust position the most up and down, it is ensured that tyre surface can well and pulley contact, it is ensured that tyre surface is carried the most smoothly, unshifts
During cutting tyre surface, cutting knife cylinder piston rod stretches out, and cutting knife extends downwardly from cutting tyre surface, forms oblique otch in the side of tyre surface, after softening by Infrared Heating, overlaps with the slant cutting edge of opposite side and then pastes, and coincideing property of crop is good.Chute plays support cutting knife and the effect of guiding.The front side board of rectangular frame, back side panel and the cylinder connection seat reached outside rectangular frame play spacing effect.When cutting knife cylinder piston rod stretches out, when cylinder connection seat moves to downwards contact with back side panel, cutting knife can not move again.Upwards retract when moving to contact with front side board and can not move again.
Compact overall structure of the present invention, floor space are little.
As preferably: described conveying roller is three.
As preferably: the angle of inclination of described rectangular frame is 30 °-60 °.So, the angle of inclination of the otch of tyre surface is 30-60 °, beneficially the overlap joint of the otch of both sides.
In such scheme: described roller mounting bracket includes top board and n shape installing plate, described roller mounting bracket is fixed on entablature by top board, the upper transverse plate of described n shape installing plate is bolted on top board, and described roller is arranged on by rotating shaft between two vertical plate of n shape installing plate.
The invention has the beneficial effects as follows: the present invention is reasonable in design, simple in construction, the rectangular frame tilted by design, it is achieved cutting knife cuts tyre surface at a slant, tyre surface otch is inclined-plane so that the identical property of the crop of tyre surface both sides is greatly improved, the final quality improving tire.By arranging swing arm, installing pulley on swing arm, swing arm can adjust position the most up and down, it is ensured that tyre surface can well and pulley contact, it is ensured that tyre surface is carried the most smoothly, unshifts.
