Description

The absorption rotary reversing device that the disposable hygienic paper product is produced

Technical field

The present invention relates to the production facilities of disposable sanitary articles, the absorption rotary reversing device of disposable hygienic paper product production specifically.

Background technology

Absorption rotation direction reverser is a kind of equipment on the disposable sanitary articles production line, and its significant feature is after the disposable sanitary articles absorption rotation, makes the product change of direction, to adapt to the production requirement of follow-up station.Oldfashioned absorption rotation direction reverser is owing to adopt the type of drive of gear mesh, cause Suction cup assembly in adsorption production, the rotation of sucker itself is still being carried out, angle can't be constant when making the product commutation, when high speed, cause the product reject rate high, and have gas leak phenomenon, cause absorption unstable.And complex structure also is subjected to product specification and adsorption number quantitative limitation simultaneously, improves difficulty.Directly influence production efficiency and commercial efficiency.

Summary of the invention

The objective of the invention is:, provide a kind of absorption to shift transfer direction reverser stable, that angle is constant and absorption quantity can conveniently be adjusted when shifting by improvement to existing installation.

The technical solution that realizes the object of the invention is as follows:

The absorption rotary reversing device that the disposable hygienic paper product is produced, comprise air-breathing ring 4, air-breathing ring 4 one side axial end captive joints dowel disc 3, have through hole on the dowel disc 3, main bearing seat 2 is fixed on the dowel disc 3, air-breathing ring 4 opposite side axial ends are rotating disc 10, main shaft 1 is connected with rotation disk cover 9 by main bearing seat 2, rotation disk cover 9 is connected with rotating disc 10, rotating disc 10 footpath uniform the axis hole more than four that makes progress, the hollow shaft 6 of sucker 12 bottoms is located in the axis hole of rotating disc 10, is provided with air intake passage and transmission device between main shaft 1 and the hollow shaft more than four 6, it is characterized in that:

Described transmission device is a cam drive, comprises cam chair 5, and cam chair 5 is a ring-type, is fixed on the main bearing seat 2 by cooperating seam, has the spiral prominence race on the ring wall of ring-type cam chair 5; Hollow shaft 6 lower ends of described sucker 12 are connecting cam arm 7, and cam 8 is housed on the cam arm 7, and cam 8 is positioned at the spiral prominence race on the cam chair 5; The hollow shaft 6 of sucker 12 bottoms by bearing fixing in rotating disc 12 axis hole radially.

Useful technique effect of the present invention is embodied in following several aspect:

1, the present invention is improved to the cam chair assembly with the type of drive that oldfashioned adsorbs the gear mesh of rotary reversing device, with rotating disc, Suction cup assembly, be installed on the main shaft, air-breathing ring and cam pack are installed in respectively on dowel disc and the main bearing seat, commutate in the time of by rotation, guaranteed the distance between the product, satisfied under the situation of any rotative speed, can both guarantee that product commutates and spacing is constant.

2, the design of this device overhead cam assembly has guaranteed that the angle of the accuracy of the anglec of rotation and material absorption is constant, promptly Suction cup assembly whenever rotate a certain angle rotating disc on request angle be rotated.And sucker rotation of self when adsorption production stops.On request angle is rotated when adsorption production not, so just guaranteed product when absorption and the angle of sucker constant.

3, this device replaces gear transmission with cam, according to different product sucker quantity is set arbitrarily easily, by the length of change cam arm, but the anglec of rotation of regulated at will sucker.

4, this device is provided with three air flues on the side of air-breathing ring.When production line high-speed turns round, promptly speed can guarantee also that greater than 200 meters/timesharing product firmly is adsorbed on the sucker, can not change by occurrence positions, has realized that absorption is stable, shifts accurately.

5, apparatus of the present invention are reasonable in design, and are simple and compact for structure, and operation, adjustment and maintenance are all convenient, greatly reduce reject rate, have improved production efficiency.

The specific embodiment

Below in conjunction with accompanying drawing, the present invention is done to describe further by embodiment.

Embodiment 1:

The absorption rotary reversing device that the disposable hygienic paper product is produced, comprise air-breathing ring 4, air-breathing ring 4 one side axial end captive joints dowel disc 3, have through hole on the dowel disc 3, main bearing seat 2 is fixed on the dowel disc 3, air-breathing ring 4 opposite side axial ends are rotating disc 10, main shaft 1 is connected with rotation disk cover 9 by main bearing seat 2, rotation disk cover 9 is connected with rotating disc 10, rotating disc 10 footpath uniform the axis hole more than four that makes progress, the hollow shaft 6 of sucker 12 bottoms is located in the axis hole of rotating disc 10, is provided with air intake passage and transmission device between main shaft 1 and the hollow shaft more than four 6, it is characterized in that:

Described transmission device is a cam drive, comprises cam chair 5, and cam chair 5 is a ring-type, is fixed on the main bearing seat 2 by cooperating seam, has the spiral prominence race on the ring wall of ring-type cam chair 5; Hollow shaft 6 lower ends of described sucker 12 are connecting cam arm 7, and cam 8 is housed on the cam arm 7, and cam 8 is positioned at the spiral prominence race on the cam chair 5; The hollow shaft 6 of sucker 12 bottoms by bearing fixing in rotating disc 12 axis hole radially.

Connecting aspirate tube 11 on the air-breathing ring 4.

Uniform pore on the adsorption plane of sucker 12.

The other end of main shaft 1 is connecting actuating unit.

Principle of work

When producing product, at first to determine the number of Suction cup assembly according to design, sucker 12 is eight as shown in Figure 1.This is to guaranteeing product stable extremely important in the process that shifts.Rotating disc 10 correspondence positions that match with Suction cup assembly hollow shaft 6 are made corresponding change simultaneously.Suitably change the number of suction hole on the rotating disc then according to the size of deisgn product, guarantee the stability of product in shifting adsorption process.

During normal operation, when rotating disc 10 drove the Suction cup assembly rotation, by the effect of cam 8 and cam arm 7, cam 8 drives hollow shaft 6 and sucker 12 radially rotates at the axis hole center around rotating disc, before arriving last delivery system, the rotation of hollow shaft 6 and sucker self stops.When arrive transmitting the position, transmission system passes to sucker 12 to product, and Suction cup assembly is air-breathing by hollow shaft 6 beginnings simultaneously, and the pore by sucker 12 is adsorbed on product on the adsorption plane of sucker 12.Then, rotatablely moving of self restarted.Before arriving transferring position, the rotation of self stops once more, and angle is constant when transmitting product like this, air-breathing end in the process of transmitting product.There has not been adsorption affinity between sucker and the product.At this moment, product has passed to next process.Thereby realized the function of absorption rotation commutation.
