Abstract
The utility model provides a plate-making roller, which comprises an upper rolling shaft, a lower rolling shaft and a roller body, wherein one end of the upper rolling shaft is arranged at the top end side of the roller body by welding; one end of the lower rolling shaft is arranged at the bottom end side of the roller by welding; both the center of the upper rolling shaft and the center of the lower rolling shaft are aligned with the center of the roller body; a cylindrical cavity is formed in the roller body; the cavity is provided with two or more disc-shaped supporting plates; the peripheries of the supporting plates are connected with the roller body by welding and the supporting plates are made of metal materials. During printing, the plate-making roller provided by the utility model does not deform even when being in relatively great pressure, so that the printing effect and the service time of the roller are both ensured.
Description
Technical field
The utility model relates to a kind of printing equipment, particularly, relates to a kind of plate-making roller.
Background technology
Plate-making is columniform part with roller, divide and drive and driven voller, be widely used in as circular screen printer, digital-code printer, mine conveying equipment, in all kinds of drive transfer systems such as papermaking and package packing machine, usually adopt seamless steel pipe to make, also looking different process, need to adopt such as aluminium alloy, stainless steel, two phase stainless steel, steel-casting, the solid alloy steel core that forges be material.
Plate-making mainly contains the just operations compositions such as car, first revisal static balance, spindle nose interference erection welding, finish turning and smart dynamic balance checking of roll body with the production of roller.If form and position tolerance is required, below 0.2mm, after finish turning, to need cylindrical grinder or roll grinder grinding as circularity, cylindricity and linearity etc.Effects on surface hardness has requirement, needs to increase heat treatment step.After the roller moulding, for antirust, anti-corrosive, the wear-resisting and needs that support, also need surface treatment or coat as spray paint, the operations such as zinc-plated, TEFLON spraying, rubber coating, chromium plating, ceramic spraying and oxidation.By size, classify, have that large-scale (length can reach more than 10 meters as roller for papermaking equipment, diameter is more than 1500mm), have small-sized as the flat carrier roller used on Belt Conveying on automatic production line (in 1 meter length, diameter is also in 159mm).By being used for minute, have to guarantee transmitting accuracy as the roller on digital laser printer, had filter pressing as the felt wrapped roll on papermaking equipment, the support carrying roller that pair dimension precision requirement is not high is arranged, the roller that the heat exchange requirement is arranged, also have the roller of heavier-duty filter pressing etc.
But existing plate-making is hollow often with roller, when depended on pressure prints, due to pressure, when larger, roller can be out of shape, and has affected on the one hand the effect of printing, and another side has also reduced the service life of roller.Therefore, be necessary to output a kind of novel plate-making roller.
The utility model content
The purpose of this utility model is to overcome the defect of above-mentioned prior art existence and a kind of plate-making roller is provided, the plate-making that the utility model provides uses roller when printing, even while running into larger pressure, roller can not be out of shape yet, guaranteed on the one hand the effect of printing, another side has also guaranteed the service life of roller.
The purpose of this utility model is achieved through the following technical solutions, a kind of plate-making roller, comprise roll shaft, lower roller bearing, and cylindrical shell, described upper roll shaft is arranged on the top end face of described cylindrical shell by welding manner, described lower roller bearing is arranged on the bottom face of described cylindrical shell by welding manner, the center of described upper roll shaft and lower roller bearing and the center superposition of described cylindrical shell, the inside of described cylindrical shell is provided with columniform cavity, described cavity is provided with discoid gripper shoe, the quantity of described gripper shoe is more than 2 or 2, the surrounding of described gripper shoe and described cylindrical shell link together by welding manner.
Preferably, the spacing between described gripper shoe is 10～30cm, and further preferred, the spacing between described gripper shoe is 20cm.
Preferably, the quantity of described gripper shoe is 3.
Preferably, the material of described gripper shoe is aluminium alloy or stainless steel.
Compared with prior art, the utlity model has following beneficial effect: the plate-making that the utility model provides with roller owing in the cavity of cylindrical shell, by welding manner, being connected with discoid gripper shoe, when using plate-making to be printed with roller, even while running into larger pressure, the cylindrical shell of roller can not be out of shape yet, guaranteed on the one hand the effect of printing, another side has also avoided the service life of roller impaired, can be widely used in the plate-making technology field.
