The disposable sanitary articles roll forming die disclosed in utility model patent (number of patent application: CN201310166224.5) in May 8 2013 applying date improves existing mould, its technical scheme is: top roll adopts the embedded regulating sleeve of movable knife mold and rubber ring, fixed by drive sleeve and axis again, cushion space is formed between top roll and lower roll, alleviate the very stiff and demanding contact of up-down rollers to a certain extent, improve the single service life of mould, reduce die cost and production cost, but in the epoch of high-speed cruising, this mould time there will be following drawback:
The requirement of processing to axiality of the axis 1, in top roll is high, the many installations of parts of top roll are complicated, mounting structure adopts interference fit more simultaneously, need through knocking installation, axiality requirement cannot be reached after installation is complete, simultaneously serious to mould loss, and make top roll compress lower roll, cannot cut completely when high-speed cruising, the processing of high-axiality simultaneously improves processing cost;
Although the axis regulating sleeve 2, 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 when high-speed motion and beat, 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.
Utility model content
The technical problems to be solved in the utility model is to provide the simple roll forming die of the disposable sanitary articles of stable operation when High-speed machining simultaneously of a kind of low cost, low-loss, installation.
In order to solve the problems of the technologies described above, the technical solution of the utility model 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 bottom mould bases, the radial position of top roll is located in described top roll side by drive division and mould bases, 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 applies pressure downwards, pressure by the second location division going down to top roll and lower roll and to make top roll and lower roll contact fixing, power drives top roll to rotate by drive division, top roll rotates and drives lower roll to rotate, frictional force when reducing lower roll and top roll rotation is rotated in first location division and the second location division simultaneously.
Further, described drive division comprise to be positioned at by draw-in groove the power transmission shaft on mould bases, the connecting axle be connected with power transmission shaft and with the venting plate being 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 rollers side by side and a locating piece, 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 surface.
Further, described mould bases adopts integrative-structure or adopts sheet material welding or securing member locking mechanism.
Adopt the beneficial effect of the technical solution of the utility model:
(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 when installing;
(2) cancel the axis of top roll and the installation of regulating sleeve, install simple simultaneously, improve the coaxial accuracy after installation;
(3) apply pressure downwards by compressing member, pressure is delivered to roller and compresses downwards, the situation that when there will not be high-speed cruising, top roll is beated downwards, there will not be the incomplete situation of cutting;
(4) eliminate the axis of lower roll, reduce die cost;
(5) each modular construction is simple, and easy to process, die cost reduces greatly.
