Technical Field

The invention relates to the field of papermaking equipment, in particular to a special arc-shaped roller for a rewinding machine.

Background

The speed of the rewinding machine is usually more than 1000 m/min. The rewinding machine provided with the common arc-shaped roller has the advantages that under the working condition of high speed, paper can be adsorbed on the common arc-shaped roller, and the speed of the rewinding machine can only be reduced in order to enable the paper at the common arc-shaped roller to be quickly peeled off. In addition, because the height of the arch of the common arc-shaped roller is small, when the width of the paper web is large, the effect of the common arc-shaped roller for stretching the paper is poor, the working speed of the equipment is influenced, the width of the paper web is limited, the working efficiency of the equipment is low, and the maximum function of the equipment cannot be exerted.

Disclosure of Invention

The invention provides a special arc-shaped roller for a rewinding machine, aiming at solving the technical problem that paper can be adsorbed on a common arc-shaped roller under the working condition of high speed, so that the working efficiency of the rewinding machine is influenced.

The object of the invention is achieved in the following way: the roller type roller device comprises two mounting bases, an arc-shaped shaft is arranged between the two mounting bases, a plurality of rollers penetrate through the arc-shaped shaft, the rollers are fixed on the arc-shaped shaft through bearings, and grooves along the circumferential direction are formed in the rollers.

One of the installation bases is a fixed base, the other one is an adjusting base, and two ends of the arc-shaped shaft are respectively fixed in the fixed base and the adjusting base through bearings.

The adjusting seat is internally provided with a worm gear and a worm which are meshed with each other in a penetrating manner, the worm is fixed in the adjusting seat through a bearing, one end of the worm is fixed with a handle, the handle extends out of the adjusting seat, and the worm gear is arranged on the arc-shaped shaft in a penetrating manner.

And a locking screw penetrates through the adjusting seat.

The adjusting seat is provided with a pointer, the pointer is fixed at one end of the arc-shaped shaft, and the adjusting seat is provided with scales.

The arch height of the arc-shaped shaft ranges from 20 mm to 40 mm.

The roller is fixed on the arc-shaped shaft through a bearing.

Compared with the prior art, the paper peeling device has the advantages that the paper at the arc-shaped roller can be quickly peeled off under the working condition of high vehicle speed by arranging the grooves on the arc-shaped roller, the arch height range of the arc-shaped roller is limited, the arc-shaped roller can adapt to the ultra-wide paper web width, and the height of the arc-shaped roller can be more conveniently adjusted by arranging the adjusting seat.

Detailed Description

As shown in the attached drawings, the paper rewinding machine comprises two mounting bases 1, an arc-shaped shaft 2 is arranged between the two mounting bases 1, the arch height of the arc-shaped shaft 2 ranges from 20 mm to 40 mm, the arc-shaped roller special for the rewinding machine can stretch paper with larger paper web width, the rewinding machine can further adapt to various paper web widths of the paper, a plurality of rollers 3 penetrate through the arc-shaped shaft 2, the rollers 3 are fixed on the arc-shaped shaft 2 through bearings, the bearings adopt roller bearings and are filled with lubricating ester, grooves 4 along the circumferential direction are formed in the rollers 3, when the arc-shaped roller works, the rollers 3 rotate at a high speed, air penetrates through the grooves 4 at a high speed to form air flow, and the air flow blows the joint of the paper and the rollers 3, so that the paper is quickly peeled from the arc-shaped roller.

The installation base 1 one be fixing base 5, another is adjusting seat 6, the both ends of arc axle 2 are fixed respectively in fixing base 5 and adjusting seat 6 through the bearing, adjust the height of seat 6 adjustable arc roller through rotating.

Adjust seat 6 in wear to be equipped with intermeshing's worm gear, the worm passes through the bearing to be fixed in adjusting seat 6, the one end of worm is fixed with handle 9, and outside handle 9 stretched out and adjust seat 6, the worm gear was worn to establish on arc axle 2, through rotating handle 9 for the worm gear meshes the transmission, drives the arc pole and rotates, thereby adjusts the height of arc roller.

The adjusting seat 6 is provided with a locking screw 7 in a penetrating mode, and the locking screw 7 can lock the worm, so that the worm cannot rotate, and the height of the arc-shaped roller is fixed.

Adjust the seat 6 on be equipped with pointer 8, pointer 8 is fixed in the one end of arc axle 2 to can rotate together according to arc axle 2, be equipped with the scale on adjusting the seat 6, through observing the height of the directional adjustable arc roller of pointer 8.

It is worth mentioning that: the height of the curved roll of the present invention means: the distance from the highest point of the arc-shaped roller to the horizontal plane; the camber of the curved roll is a reaction of the degree of curvature of the curved roll.

The working process of the invention is as follows: firstly, the arc-shaped roller is installed on the rewinding machine, the locking screw 7 is unscrewed, the handle 9 is rotated, the worm and gear are meshed for transmission, so that the height of the arc-shaped roller is adjusted, the direction of the pointer 8 is observed, when the height of the arc-shaped roller is adjusted to a proper position, the handle 9 is stopped to rotate, then the screw is screwed down, the rewinding machine starts to work, the paper drives the roller 3 to rotate at a high speed, air passes through the grooves 4 on the surface of the roller 3 at a high speed to form air flow, the air flow blows the joint of the paper and the roller 3 to enable the paper to be quickly peeled off from the arc-shaped roller, the paper can be quickly peeled off from the arc-shaped roller, the speed of the rewinding machine does.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the overall concept of the present invention, and these should also be considered as the protection scope of the present invention.
