Description
Technical field
The present invention relates to disposable sanitary articles manufacturing mechanism and manufacture field, especially relate to a kind of cam driving gear of disposable sanitary articles.
Background technique
Cam can be defined as the parts that has curved surface or crank slot, utilizes it to swing or revolution, another assembly-follower can be made to provide the motion preset.The large portion, path of follower is limited in a chute, to obtain toward covering motion.In the stroke that it is replied, sometimes rely on the weight of itself, but some mechanism obtains definite action, often using spring as the power of reply, some then utilizes guide groove, makes it move on specific path.
Because the layout of product processes in disposable sanitary articles manufacture process, more or less need semi-finished product to be carried out commutation conveying, commutation conveying generally all applies to cam driving gear, the cam that traditional cam driving gear has single guide wheel rocking arm and coordinates with it, cam has left and right two groove faces coordinated with camshaft bearing.Single camshaft bearing of groove cam and the left and right groove face Spielpassung of cam path, camshaft bearing rocking in gap all can cause rocking arm sky pendulum, what camshaft bearing replaced when making circular-rotation around camshaft line contacts with two groove faces of cam path, impact is there is in camshaft bearing at the Contact of conversion groove face, and the bearing rotary direction also checker because of the contact from different groove face, these all cause camshaft bearing easy to wear and lost efficacy.Publication number is that CN1351234A cam gear illustrates a kind of double-slot cam structure in addition, it on the periphery of cam from outside to inside, two guide grooves are set, an one shallow dark guide groove forms 4 groove faces altogether, the axial direction that one of them groove face also prolongs cam internally stretches out, this not competent processing of step universal cutter extended internally, the groove inwardly stretched out in addition impairs the intensity of the cam disk ancient piece of jade, round, flat and with a hole in its centre for carrying upper strata cam, and this kind of structure also defines the bearing that guide wheel can only use two same diameter in addition.
Summary of the invention
The object of the invention is to solve above-mentioned Problems existing, provide structure simple, the easy to use cam driving gear delaying a kind of disposable sanitary articles of camshaft bearing wearing and tearing.
The object of the invention is to realize as follows: a kind of cam driving gear of disposable sanitary articles, has the cam disk of ring, and its inner ring is socketed on stationary axle by key or screw; Also there is guide wheel and rocking arm, the outer peripheral surface of described cam disk have circulation around guide groove, and on the axial direction of described cam disk, there is projection; One end of described guide wheel is distributed in guide groove, and its other end is connected with being driven workpiece by rocking arm.
The cam driving gear of above-mentioned a kind of disposable sanitary articles, described guide wheel has large bearing, little bearing, guide wheel shaft and axle sleeve, and described large bearing, axle sleeve and little bearing are arranged on successively to be had on the guide wheel shaft of step, and the end of described guide wheel shaft has screw thread.
The cam driving gear of above-mentioned a kind of disposable sanitary articles, described guide wheel at least has two groups, and decile is arranged on the excircle of cam disk.
The cam driving gear of above-mentioned a kind of disposable sanitary articles, described guide wheel has the configuration of six groups, eight groups or ten groups any amount.
The cam driving gear of above-mentioned a kind of disposable sanitary articles, described rocking arm is in " Z " font, two horizontal edge respectively has a mounting hole, described guide wheel shaft end is inserted in a mounting hole of rocking arm and by nut locking, the another one mounting hole of described rocking arm is fixedly connected with driving workpiece.
The cam driving gear of above-mentioned a kind of disposable sanitary articles, described rocking arm, is improved to hypotenuse structure for connecting two vertical edges installing horizontal edges.
The cam driving gear of above-mentioned a kind of disposable sanitary articles, described cam disk has secondary guide groove from periphery to inner ring direction, two guide grooves have shared the first groove face, second groove face of side and the 3rd groove face form step in addition, and the width of outside second groove face and the first groove face is greater than the width of inner 3rd groove face.
The cam driving gear of above-mentioned a kind of disposable sanitary articles, the periphery of described large bearing all the time with the first groove face surface contact, the outer peripheral surface of described little bearing contacts with the second groove face all the time, and the respective rotation direction of large bearing and little bearing is fixed, and rotation direction is contrary.
The cam driving gear of above-mentioned a kind of disposable sanitary articles, described guide groove has four sections of projections, is respectively guide groove horizontal segment, and guide groove promotes tilting section, the protruding horizontal segment of guide groove and guide groove decline tilting section.
Advantage of the present invention: 1, cam driving gear of the present invention adopts the design feature of double-slot cam, can significantly improve the working life of camshaft bearing compared with tradition list groove cam;
2, two camshaft bearings of double-slot cam contact all the time with the one side of a guide groove in double flute separately, and it is constant that rotation direction is fixed in each self-sustaining of camshaft bearing, improves the life-span of cam and guide wheel;
3, compared with existing double-slot cam, by original double step, four sides guide groove is improved to guide groove face, 3, separate unit rank, decreases a complicated processing face, decreases amount of finish, reduce difficulty of processing.
4, the vertical edge of the rocking arm of conventional " Z " font is improved to hypotenuse, when the centre distance of the mounting hole of two horizontal edges is constant, enhances wall thickness and the intensity of rocking arm, make to be competent at carrying more high pulling torque.
5, another important result of double-slot cam is that the quality of fit of guide wheel bearing and cam path is improved, double-cam bearing is monolateral separately contacts the Spielpassung substituting single camshaft and hold all the time, reduce by the sky pendulum stroke driving workpiece when doing commutation and rotating, elimination rocking arm makes delayed and shaking phenomenon during divertical motion, effectively improves rocking arm and makes 90 ° of precision turned to.
