Description

A kind of transition roller

Technical field

The utility model relates to paper diaper production equipment field, particularly a kind of transition roller.

Background technology

Existing paper diaper are produced and are comprised multiple operation, such as produce the equipment of absorber, the equipment met is pasted in double left and right, to the equipment etc. of paper diaper circular arc trimming, whole paper diaper are produced and are made up of multiple series-operation equipment, and transition roller plays procedure connection in paper diaper production process, the effect of conveying guiding, but transition roller in guide process often because guide roller occurs installing insecure, appearance is rocked, the situations such as inclination, or due to viscose, dirts etc. run in transition roll shaft, transition roller is caused to rotate dumb, bearing blocks, there are the situations such as abnormal sound, then directly cause clamping stagnation what is more, stuck situation, and market does not also have the transition roller made improvements for above situation.

Utility model content

Therefore, for above-mentioned problem, the utility model provide a kind of rational in infrastructure, good airproof performance, installation firmly, rotate transition roller flexibly.

For realizing above-mentioned technical matters, the solution that the utility model is taked is: a kind of transition roller, comprise supporting seat, be fixed on two right angle seats on supporting seat, be located at the guide roller between two right angle seats, described guide roller comprises the transition roll shaft be located in guide roller, be located at the bearing seat at transition roll shaft two ends respectively, be located at the bearing between transition roll shaft and two bearing seats respectively, described transition roll shaft two ends are also respectively equipped with circlip for shaft by end to direction in the middle part of transition roll shaft vertically, cover of dust, one-level labyrinth packing, secondary maze seals, axle rigidity back-up ring, described circlip for shaft, cover of dust, one-level labyrinth packing, secondary maze sealing is located at bearing away from side in the middle part of transition roll shaft, axle rigidity back-up ring is located at bearing side in the middle part of transition roller axle.

Further improvement: described bearing seat is provided with metal insert, described metal insert is located on bearing seat near bearing side.

By adopting preceding solution, the beneficial effects of the utility model are: by arranging the array mode of double-layer labyrinth sealing at the two ends of transition roll shaft, dust-proof path is made to reach maximization, effective prevention dust, water, the dirts such as viscose run into guide roller inner, bearing and rotating part rotate flexibly, there will not be abnormal sound, clamping stagnation or the bad phenomenon such as stuck, cover of dust further enhances antifouling effect, and to be positioned at bearing at the two ends of transition roll shaft be respectively equipped with again a circlip for shaft and an axle rigidity back-up ring away from transition roll shaft side with near transition roll shaft side, back-up ring mainly plays the effect of axial restraint, add the cooperation of head bearing and bearing seat, transition roll shaft is made to install firmly, without rocking, the bad defects such as inclination.

Accompanying drawing explanation

Fig. 1 is the utility model example structure schematic diagram;

Fig. 2 is the axial cutaway view of the utility model embodiment guide roller right-hand member.

Detailed description of the invention

Now with specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.

With reference to figure 1 and Fig. 2, a kind of transition roller, comprise supporting seat 1, be fixed on two right angle seats 2 on supporting seat 1, be located at the guide roller 3 between two right angle seats 2, described guide roller 3 comprises the transition roll shaft 31 be located in guide roller 3, the bearing seat 32 being located at transition roll shaft 31 two ends and the bearing 33 be located between transition roll shaft 31 and two bearing seats 32, described bearing seat 32 is provided with metal insert 321, described metal insert 321 is located on bearing seat 32 near bearing 33 side, cross-sectional plane similar " Z " shape of described metal insert 321, described metal insert 321 both can the rigidity of reinforced shaft bearing 32, the conformability of diaxon bearing 32 size and position in installation and use procedure can be ensured again, described transition roller bearing 31 rotates and drives guide roller 3 to rotate, described transition roll shaft 31 two ends are also respectively equipped with circlip for shaft 34 by end to direction in the middle part of transition roll shaft 31 vertically, cover of dust 35, one-level labyrinth packing 36, secondary maze sealing 37, axle rigidity back-up ring 38, described circlip 34, cover of dust 35, one-level labyrinth packing 36, secondary maze sealing 37, axle rigidity back-up ring 38 is common on market and easy acquisition, therefore its structure is not described in detail at this, described circlip for shaft 34, cover of dust 35, one-level labyrinth packing 36, secondary maze sealing 37 is located at bearing 33 away from side in the middle part of transition roll shaft 31, axle rigidity back-up ring 38 is located at bearing 33 side in the middle part of transition roll shaft 31.

By adopting preceding solution, the utility model is by arranging the array mode of double-layer labyrinth sealing at the two ends of transition roll shaft, dust-proof path is made to reach maximization, effective prevention dust, water, the dirts such as viscose run into guide roller inner, bearing and rotating part rotate flexibly, there will not be abnormal sound, clamping stagnation or the bad phenomenon such as stuck, cover of dust further enhances antifouling effect, and to be positioned at bearing at the two ends of transition roll shaft be respectively equipped with again a circlip for shaft and an axle rigidity back-up ring away from transition roll shaft side with near transition roll shaft side, back-up ring mainly plays the effect of axial restraint, add the cooperation of head bearing and bearing seat, transition roll shaft is made to install firmly, without rocking, the bad defects such as inclination.

Although specifically show in conjunction with preferred embodiment and describe the utility model; but not departing from the category of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
