Abstract

The utility model relates to a roller in mechanical equipment, in particular to roller in thin material conveying. The purpose is as follows: a roller is designed to simultaneously give a lateral tension to a conveyed material from the center to both sides during conveying or changing the conveying direction. The technical scheme is that the arc-shaped roller comprises a roller support, an arc-shaped shaft, bearings, a roller and the like, and is characterized in that the arc-shaped shaft is an arc with a certain curvature radius on the axis, the shaft is a cylinder with the same radius, the arc-shaped shaft is sleeved with the bearings, and the roller is sleeved on the bearings.

Description

A kind of bowed roller

Technical field

The utility model relates to the roller in the mechanical equipment, the roller during particularly thin material is carried.

Background technology

Make at numerous printing machinery and thin material, in the processing equipment, all relate to roller, because the effect that roller played is the sense of motion that supports thin material or change thin material, traditional roller all is d-axis line styles, and thin material does not have horizontal tension in course of conveying, wrinkling easily.

The purpose of this utility model is: design a kind of in conveying or change throughput direction process, simultaneously to being transferred roller by the horizontal tension on middle mind-set two limits of material.

Summary of the invention

The technical solution of the utility model is a kind of bowed roller, constitute by roller bearing, arc shaft, bearing, cylinder, it is characterized in that described arc shaft is that axis is the camber line that the certain curvature radius is arranged, axle is the cylinder of same radius, on arc shaft, be set with a plurality of bearings side by side, suit cylinder on bearing.

Be provided with spacer ring between the bearing of described suit.

Be provided with the adjustment radian hole of work radian size at arc shaft.

Because this roller is whole to be arc, natural energy provides a horizontal tension by middle mind-set two limits to being transferred material, and a plurality of employing bearings and roller frame reach the purpose that constitutes arc, and can be as required by adjusting the radian hole, roller is turned an angle, just can cause the purpose of real work face radian adjustable size.

Advantage of the present utility model is that this camber roller can play the purpose of smooth thin-type material, makes material wrinkling by overcoming after it, improves the quality of machining object.

Description of drawings

Accompanying drawing 1 is the utility model integral structure scheme drawing.

Accompanying drawing 2 is the utility model cross section structure scheme drawing.

Among the figure: 1-bearing seat, 2-gland, 3-tapered sleeve, 4-screw, 5-adjust radian hole, 6-arc shaft, 7-nut, 8-gland, 9-bearing, 10-cylinder, 11-spacer ring.

The specific embodiment

By embodiment the utility model is further described in conjunction with the accompanying drawings, but is not limited to embodiment.

Adopt general machinework and cross the gland 2 of processing in the roller seat according to roll shaft R, tapered sleeve 3, screw 4 and select the bearing seat 1 that matches with roll shaft for use, roll shaft is processed into the arc shaft of certain curvature, according to the length of driving surface and the fine degree of driving surface requirement, the cylinder of working roll, select the bearing that matches with the cylinder internal diameter for use, bearing carrier ring is contained on the roll shaft, roll sleeve is sleeved on the bearing, can adopt roll sleeve of two bearing suits, or roll sleeve of a bearing suit, install spacer ring additional between bearing and bearing, the spacer ring external diameter is not more than the bearing inner sleeve external diameter, a plurality of bearings, constitute bowed roller on roll sleeve and the major part axle.

Claims

1, a kind of bowed roller, be made of roller bearing, arc shaft, bearing, cylinder, it is characterized in that described arc shaft is that axis is the camber line that the certain curvature radius is arranged, axle is the cylinder of same radius, on arc shaft, be set with a plurality of bearings side by side, suit cylinder on bearing.

2, a kind of bowed roller according to claim 1 is characterized in that: be provided with spacer ring between the bearing of described suit.

3, a kind of bowed roller according to claim 1 is characterized in that: the adjustment radian hole that is provided with work radian size at arc shaft.
