Sanitary napkin clad diverter and orientation diversion method
Technical field
The present invention relates to a kind of novel sanitary towel clad diverter and orientation diversion method, belong to the sanitary napkin production equipment and make the field.
Background technology
Existing sanitary napkin clad diverter, on structural design: 1, the cone pinion on a plurality of negative pressure air intake devices through with the cooperating of large bevel gear, reach the purpose of orientation conversion, the pattern of its work be to move continuously.2, the inlet scoop in the negative pressure air intake device is the axle inlet scoop.Its weak point: the one, the negative pressure air intake device adopts continuously, does not have the operational mode of discontinuous point, is prone to cause last process to be connected not in place with next procedure, influences the operate as normal of next procedure; The 2nd, suction air volume is not enough, is prone to cause sanitary napkin in the process of operation, by falling down on the negative pressure air draught face; The 3rd, complex structure, manufacturing cost is high, and applicable performance is poor.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of can either sanitary napkin being adsorbed on the negative pressure air intake device, again can be with the clearance-type sanitary napkin clad diverter and the orientation diversion method of negative pressure air intake device conversion position.
Design: in order to realize above-mentioned purpose of design.1, on the axle, fixed disk is enclosed within on the outer shaft and interior axle does not change, outer shaft changes, and is one of characteristic of the present invention in edge cam was fixed on.The purpose of doing like this is: when the negative pressure air intake device on being positioned at fixed disk rotates with fixed disk; Edge cam in being fixed on the axle is motionless, so the balance staff in the negative pressure air intake device and the bearing on the balance staff thereof drive progressively conversion position of negative pressure air intake device along in the edge cam working face rotating process; Until changing to 90 degree; Reset then, gap operation, again conversion position, reset, like this gap operation, up to end-of-job.2, the matching Design of negative pressure air intake device and ring packing cover is two of a characteristic of the present invention.The purpose of doing like this is: both satisfied sanitary napkin in the process of conversion position; Through the negative pressure air intake device sanitary napkin is produced negative-pressure adsorption; Realized that again the negative pressure behind the sanitary napkin conversion position cuts off separation automatically; That is to say that in the process of sanitary napkin in orientation conversion, the negative pressure air intake device is adsorbed on sanitary napkin on the air draught face of negative pressure air intake device through the negative pressure in the ring packing cover firmly; After sanitary napkin is accomplished the orientation conversion; Air port in the negative pressure air intake device and ring packing cover break away from, and when being positioned at sanitary napkin on the negative pressure air intake device air draught face and separating with the air draught face of negative pressure air intake device automatically, are siphoned away by the negative pressure air intake device of subsequent processing.3, the edge cam working face by last domatic, down domatic, horizontal plane constitutes, and is three of characteristic of the present invention.The purpose of doing like this is: because the domatic gradient of edge cam is different; Can make balance staff bearing at end in the negative pressure air intake device when cam working face rotates; Force the negative pressure air intake device with balance staff generation bearing change, reset, move; Reach the purpose of gap work, guaranteed the operation coupling in the sanitary napkin manufacture process.4, bearing block is designed to the design that hollow core structures and middle part have the inlet scoop; It is four of characteristic of the present invention; The purpose of doing like this is: the two ends up and down of air-cored axis's bearing adopt bearing both to realize and being connected of rotating shaft, rotating shaft and air draught box company; Play rotating shaft again and drive the purpose that the air draught box rotates; Simultaneously strengthened ventilation again, improved negative pressure and inhaled negative ventilation, avoided because the defective that the sanitary napkin that negative pressure suction air volume deficiency causes comes off from the air draught face of air intake device in running.
Technical scheme 1: sanitary napkin clad diverter; Outer shaft (23) is enclosed within on the interior axle (35); In axle (35) be positioned on the bearing block of gripper shoe (32) and axle (35) does not rotate; Fixed disk (19) is enclosed within on the outer shaft (23), and edge cam (6) is enclosed within interior axle (35) and goes up and be positioned at fixed disk (19) simultaneously, and 2 or many negative pressure air intake devices (38) are equally spaced and on fixed disk (19) circumferential end surfaces and with fixed disk (19), rotate and changing location.
Technical scheme 2: the bearing change method of sanitary napkin clad diverter, actuating unit drive the outer shaft rotation, and outer shaft drives fixed disk and rotates; Fixed disk drives that the balance staff bearing at end is along in the edge cam working face rotating process in the negative pressure air intake device, and balance staff drives the negative pressure air intake device through connecting rod and progressively rotates, (1) when bearing movable to cam during domatic most significant end; The negative pressure air intake device revolves and turn 90 degrees, and gets into the horizontal plane of cam working face then, and the negative pressure air intake device does not rotate; (2) rotated by cam horizontal plane domatic lowest surfaces under cam when holding axle, bearing is in domatic rotation process on cam, and balance staff drives the negative pressure air intake device through connecting rod and progressively rotates; When bearing movable under cam during domatic least significant end, the negative pressure air intake device resets, and gets into the horizontal plane of cam working face; The negative pressure air intake device does not rotate, (3) when bearing movable to cam during domatic most significant end, the negative pressure air intake device revolves and turn 90 degrees;, like this gap circulation, until end-of-job.
The present invention compares with background technology, and the one, structural design is novel, unique, simple, practical; The 2nd, adopt the edge cam working face to inhale the setting face of negative tool face azimuth conversion as negative pressure; Not only realized the smooth conversion in negative pressure air intake device orientation; And realized the gap work of negative pressure air intake device, guaranteed reliable linking the between last process and next procedure; The 3rd, the matching Design of negative pressure air intake device and ring packing cover, not only the negative pressure amount is big, and has realized the purpose that automatically disconnected wind, sanitary napkin separate with the air draught face of negative pressure air intake device automatically; The 4th, bearing block is designed to hollow core structures and the middle part has the inlet scoop, has not only solved the negative pressure suction air volume defect of insufficient that background technology exists, and has played the double effects of bearing block and guide duct.
