Description
Technical field
The invention belongs to disposable sanitary articles field, refer in particular to a kind of disposable sanitary articles roll forming die.
Background technology
Disposable sanitary articles comprises paper diaper, sanitary napkin, panty liner, paper bib, breast pad, paper shoe-pad etc., current existing production disposable sanitary articles adopts the structure of roll forming die to be: top roll is forming cutter, be divided into forming cutter notch portion, protective sleeve part, axis part, blade portion proportion by subtraction protective sleeve partly exceeds 0.01～0.05mm, and edge of a knife sharpening is sharp; Lower roll is divided into smooth roll body part and axis part.Upper and lower roll is assemblied in same frame, and lower roll is fixed, and top roll can move up and down, by the pressurization of spring (or air pressure, oil pressure) device, upper and lower roll rotates, and realizes rolling cut moulding, but after producing one-phase, the tired chap of forming cutter edge of a knife part, lower roll tool marks depression, just need to pull down regrinding.
The patent of invention in May 8 2013 applying date (number of patent application: CN201310166224.5) disclosed disposable sanitary articles roll forming die improves existing mould, its technical scheme is: top roll adopts the embedded regulating sleeve of movable knife mold and rubber ring, by drive sleeve and axis, fix again, give between top roll and lower roll and form cushion space, alleviated to a certain extent the very stiff and demanding contact of up-down rollers, improved the single service life of mould, die cost and production cost have been reduced, but in the epoch of high-speed cruising, this mould time there will be following drawback:
1, the processing of the axis in top roll to axiality require high, the parts of top roll are installed complexity more, on mounting structure, adopt interference fit more simultaneously, need through knocking installation, after installation, cannot reach axiality requirement, simultaneously serious to mould loss, and make top roll cannot compress lower roll, the in the situation that of high-speed cruising, cannot cut completely, the processing of high-axiality simultaneously improves processing cost;
Although 2, the axis regulating sleeve in top roll and movable knife mold structure can avoid top roll to wear and tear to the hard friction of lower roll, there will be and beat when high-speed motion, make cutting not exclusively;
3, present top roll lower roll is fixed on mould bases by axis, and mounting structure is complicated, and cost is high.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of low cost, low-loss, the simple roll forming die of the disposable sanitary articles of stable operation when High-speed machining simultaneously of installation.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: the roll forming die of disposable sanitary articles, comprise mould bases, lower roll and top roll, described lower roll is parallel with top roll to be mounted with on mould bases, described lower roll and top roll are cylinder, described lower roll is placed on the bottom of mould bases, and by being fixed on the first location, location division axial location of mould bases bottom, described top roll one side is by the radial position of drive division and mould bases location top roll, the second location, location division top roll axial location, the second described location division is fixedly connected with compressed part, compressed part is movably connected on mould bases, compressed part is exerted pressure downwards, pressure by the second location division going down to top roll and lower roll and make top roll and lower roll contacts fixing, power drives top roll to rotate by drive division, top roll rotates and drives lower roll to rotate, the frictional force while reducing lower roll and top roll rotation is rotated in the first location division and the second location division simultaneously.
Further, described drive division comprise by draw-in groove be positioned at the power transmission shaft on mould bases, the connecting axle being connected with power transmission shaft and with the venting plate that is fixed on top roll inner ring, described connecting axle and venting plate are fixed by draw-in groove.
Further, the first described location division and the second location division include two symmetrical keepers, and described positioning transmission part comprises two roller and locating pieces side by side, and the periphery of the periphery of described roller and lower roll and top roll is tangent.
Further, described lower roll and top roll are hollow cylinder.
Further, the periphery of described top roll is provided with cutting die, and the height of cutting die is lower than the height of top roll both sides and lower roll contact-making surface.
Further, described mould bases adopts integrative-structure or adopts sheet material welding or securing member locking mechanism.
Adopt the beneficial effect of technical scheme of the present invention:
(1) adopt draw-in groove to connect or positioning compression, without interference fit, assembling is simple, improves installation effectiveness, and reduces the damage to mould while installing;
(2) cancel the axis of top roll and the installation of regulating sleeve, install simply simultaneously, improved the coaxial accuracy after installing;
(3) by compressing member, exert pressure downwards, pressure is delivered to roller and compresses downwards, and the situation that while there will not be high-speed cruising, top roll is beated downwards there will not be the incomplete situation of cutting;
(4) cancel the axis of lower roll, reduced die cost;
(5) each modular construction is simple, easy to process, and die cost reduces greatly.
