Description

A kind of gradual change depth inclined slot nip rolls

Technical field

Rubber roller design and manufacturing technology field are the utility model is related to, is specially a kind of gradual change depth inclined slot flattening Roller.

Background technology

Rubber nip rolls usually relies on roll surface to dividing screw slotting structure to obtain flattening effect.But flatten difficulty for part Larger base material, commonly to dividing screw slotting structure to be difficult often to obtain satisfied flattening effect.

Utility model content

(1) technical problem solved

In view of the deficiencies of the prior art, the utility model provides a kind of gradual change depth inclined slot nip rolls, solves Commonly to dividing screw slotting structure flattening effect poor the problem of.

(2) technical solution

In order to achieve the above object, the utility model is achieved by the following technical programs：A kind of gradual change depth is tilted and opened Groove nip rolls, including roller core, the surface of the roller core are equipped with rubber layer, and the rubber layer surface is according to dividing helical structure to open up There is groove, for the section slotted in the rubber layer surface to be obliquely installed, angle of inclination is 20-30 °, in the rubber layer surface Groove depth is gradual change depth, and on the basis of centre, more toward both ends, its groove depth is bigger, and the helical form for forming sequence arrangement tilts The helical form of groove and ordered arrangement tilts prism.

Preferably, the rubber layer is the electro-insulating rubber layer of soft.

(3) beneficial effect

The utility model provides a kind of gradual change depth inclined slot nip rolls, possesses following beneficial effect：

The gradual change depth inclined slot nip rolls, it is rational in infrastructure simple, easy to manufacture, easy to use, it can obtain more conventional Fluting nip rolls preferably flattens effect, and the tension force of smaller can be used, avoid damage to base material, solve commonly to dividing screw slotting The problem of structure flattening effect is poor.

Brief description of the drawings

Fig. 1 is the utility model nip rolls structure diagram.

In figure：1 roller core, 2 rubber layers, 3 helical form inclined grooves, 4 helical forms tilt prism.

Embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

The example of the embodiment is shown in the drawings, wherein same or similar label represents identical or class from beginning to end As element or there is same or like element.The embodiments described below with reference to the accompanying drawings are exemplary, purport For explaining the utility model, and it is not intended that limitation to the utility model.

Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of gradual change depth inclined slot nip rolls, including Roller core 1, the surface of roller core 1 are equipped with rubber layer 2, and rubber layer 2 is the electro-insulating rubber layer of soft, and hardness is relatively low, 2 thickness of rubber layer More conventional fluting nip rolls is big by more than 50%, and the more conventional fluting nip rolls of rubber hardness is soft, and 2 surface of rubber layer is according to spiral to dividing Structure offers groove, and for the section slotted on 2 surface of rubber layer to be obliquely installed, angle of inclination is 20-30 °, on 2 surface of rubber layer Groove depth be gradual change depth, on the basis of centre, more toward both ends, its groove depth is bigger, formed sequence arrangement helical form incline The helical form of oblique groove 3 and ordered arrangement tilts prism 4, and helical form tilts 4 thinner thickness of prism, coordinates relatively low rubber layer 2 hardness, can be easier that elastic deformation occurs.

Operation principle：When base material with some tension by flattening roller surface, helical form is pressed under tension and tilts rib Column 4, while expansion effect is obtained with spiral expanding line, is pressed with the trend further toppled over, so as to obtain under inclined prism The trend extended to both sides is obtained, further enhances expansion effect；More toward both sides, inclination groove depth is bigger, tilts prism heights It is bigger, its extension trend further enhances, the expanding stroke consumed when being unfolded with this to base material, in addition, outward-dipping Prism also effectively can prevent base material from bouncing back.

In conclusion the gradual change depth inclined slot nip rolls, rational in infrastructure simple, easy to manufacture, easy to use, can obtain Obtain more conventional fluting nip rolls and preferably flatten effect, the tension force of smaller can be used, avoid damage to base material, solve commonly to dividing The problem of screw slotting structure flattening effect is poor.

In the description of this specification, reference term " one embodiment ", " some embodiments ", " example ", " specifically show The description of example " or " some examples " etc. means specific features, structure, material or the spy for combining the embodiment or example description Point is contained at least one embodiment or example of the utility model.In the present specification, to the schematic table of above-mentioned term State and may not refer to the same embodiment or example.Moreover, particular features, structures, materials, or characteristics described can be Combined in an appropriate manner in any one or more embodiments or example.
