Abstract
The utility model provides a flattening roll, which comprises a core shaft, rotary sleeve tubes, annular pins, rolling bearings, and adjusting devices, wherein each rotary sleeve tube covers and is sheathed on the core shaft, each rolling bearing is arranged between each rotary sleeve tube and the core shaft, each rotary sleeve tube is connected by the annular pins, and the two ends of the core shaft are provided with the adjusting devices. The flattening roll has the advantages that the obvious flattening effect is provided by simpler structure and less cost, and the size of flattening force is adjusted within the large range.
Description
Technical field
The utility model relates to a kind of leveling roller, particularly relates to a kind of for transmitting the leveling roller of vertically hung scroll shape or film series products.
Background technology
Due to the impact of the factors such as production environment, processing technology and production facilities itself, usually can be at the horizontal appearance of substrate surface fold in various degree in the production process of the industry base materials such as film, weaving, printing and dyeing, printing, papermaking and coating.For reducing, eliminating the wrinkle producing in base material production process, make base material obtain actv. and axially flatten, one or more leveling roller is generally installed in base material course.The leveling roller of different structure has different adaptation operating range and effect, is generally divided into spiral leveling roller and arc-shaped exhibition plain-barreled roll in prior art.
The structural principle of spiral leveling roller is, on the surface of roll body from mediad bilateral symmetry distribution left-right rotary screw thread, when base material contacts its surface with roll surface on the screw thread that tilts to both sides produce friction, the screw thread of inclination to two ends, is able to base material open and flat base material expansion.The feature of this leveling roller comprises: simple in structure, simple installation and Maintenance free; Rotating speed is high, jerk value is little, noiseless, safe and reliable and can bear larger pulling force; Roll body material has corrosion-resistant steel, rubber and plastics etc., can in the harsies environment such as steam, liquid state and high temperature, use.
The shortcoming of spiral leveling roller is that flattening ability is relatively little, only can be used as general wrinkle resistant, remove leveling roller or the deflector roll of wrinkle, and more difficult change flattens the size of power.
Arc-shaped exhibition plain-barreled roll is generally comprised of arc mandrel, antifriction-bearing box assembly, rotational sleeve, end cover, bearing and adjusting knurl etc.The manufacture of arc-shaped exhibition plain-barreled roll, that axle is curved to desired arc, on axle, being separated by spacing certain installs bearing, and cover becomes one and has the roller that arc, turning set can pivot with turning set on bearing, and the direction of arc can regulate by the handwheel on axle bed.The principle of work of arc-shaped exhibition plain-barreled roll is: turning set is when going for a stroll axle rotation, roll surface can launch and contract same, when base material starts to contact roll surface from concave arc, when running to convex arc place and leave, it is to be parallel to direction rotation longitudinally that the roll surface of bowed roller only has central part, and other each points of roll surface central authorities both sides all with longitudinal angled rotation, therefore base material has been produced to the drafting force to both sides, base material is flattened.
Arc-shaped exhibition plain-barreled roll is widely used in the industries such as weaving, printing and dyeing, printing, papermaking, film and packing, is the kind of the wide and large usage quantity of current range of use.Its shortcoming is: flattening ability is relatively little, and base material cornerite can not excessive (generally within the scope of 15 degree～30 degree), and tension force is also unsuitable excessive, otherwise easily makes film class base material produce permanent deformation, the fracture of stationery base material, and dry goods base material broadwise is crooked; In addition, according to the different situations of base material, need adjust radian direction, adjust the amplitude limited of radian.
Up to now, in the prior art, not yet there is a kind of leveling roller, with better simply structure and cost, can make the larger raising of flattening ability, and the adjusting of being convenient to the power that flattens.
Utility model content
It is a kind of for transmitting the leveling roller of vertically hung scroll shape or film series products that the utility model provides, and it has solved variety of problems of the prior art.It comprises mandrel, rotational sleeve, annular pin, antifriction-bearing box, and control apparatus; Described rotational sleeve covers and is sleeved on described mandrel, between described rotational sleeve and described mandrel, is provided with antifriction-bearing box; Between described rotational sleeve by annular pin sub-connection; Described mandrel two ends are provided with control apparatus.
One preferred embodiment in, described mandrel is rectilinear metal shaft.
Another preferred embodiment in, described mandrel is hollow tubular metal shaft.
Another preferred embodiment in, the quantity of described rotational sleeve is more than 5.
Another preferred embodiment in, the material of described rotational sleeve is corrosion-resistant steel.
Another preferred embodiment in, the surface of described rotational sleeve is coated with layer of metal chromium.
Another preferred embodiment in, the described rotational sleeve of two vicinities is provided with groove towards mandrel place, described groove is provided with described antifriction-bearing box.
Another preferred embodiment in, described rotational sleeve has identical size and dimension.
Another preferred embodiment in, described control apparatus is comprised of bolt and connecting plate.
Another preferred embodiment in, it is characterized in that, described control apparatus is adjusting knurl.
The beneficial effects of the utility model are as follows:
1) can provide larger flattening power;
2) can in scope, regulate flattening power by a relatively large margin;
3) in production or transmitting procedure, can not scratch film series products.
Accompanying drawing explanation
Fig. 1 is leveling roller schematic diagram of the present utility model.
Fig. 2 is the cutaway drawing of Fig. 1.
The specific embodiment
As shown in Figure 1, the utility model mainly comprises a mandrel 110 to overall appearance of the present utility model, and is enclosed within mandrel 110 a plurality of rotational sleeves 120 around, and the two ends of mandrel 110 are provided with control apparatus 130.
Different from traditional arc-shaped exhibition plain-barreled roll, mandrel 110 is a rectilinear hollow tubular metal shaft, but not is prefabricated into the metal shaft of arc.
Further as shown in Figure 2, mandrel 210 periphery covers have the rotational sleeve 221 and 222 of two close contacts in the assembling of rotational sleeve and mandrel; Described rotational sleeve 221 is consistent with 222 size and dimension, and there is a groove at the middle part between them, and annular pin 240 is arranged in this groove, and described annular pin 240 can make both closely close; Between described rotational sleeve 221 and 222, towards mandrel 210 places, be also provided with a groove, this groove is used for placing antifriction-bearing box, and antifriction-bearing box can drive rotational sleeve to slide on mandrel.
Finally, should also be understood that, after having read foregoing of the present utility model or embodiment, those skilled in the art can make various changes or modifications the utility model, these are equal to change and fall within equally the application's appended claims limited range.
