Abstract
The present invention relates to a kind of paper for daily use rewind rolls.After roll paper roller reaches dimensional accuracy by vehicle mill, it in surface spray-coating a layer thickness is the wear-resisting composite coating that 0.05-1.0mm joined carbide or ceramic oxide particle with the method for thermal spraying, final roughness is Ra6-20um after sealing of hole and removal surface high point, both it had been avoided that the sharp bulky grain in composite coating surface and protrusion pulled paper, paper can firmly be gripped on roller again, make roller and paper without relative displacement, and through a long time work back roller surface roughness does not decline, and meets the working condition requirement of high-speed domestic paper rewind roll.
Description
Technical field
The invention belongs to rewinding machinery equipment field, and in particular to a kind of paper for daily use rewind roll and preparation method thereof.
Background technique
Paper for daily use rewinding machine is (roll paper that such as use in toilet arrives, kitchen paper for processing our paper for daily use
Towel), main operational principle is: then body paper is wound by press polish, embossing, reaches and select fixing turn, automatic cutting, then is taken
It is cut on to band saw paper cutter.Rewind roll is core therein and key equipment.
It is worked in paper for daily use rewind roll due to the raising of the operating rate of the raising and rewinding machine of the degree of automation
Cheng Zhong, drive paper starting, stop after paper has reached defined circle number, require roller and firmly grip in paper on roller, make roller with
Paper cannot have relative displacement.
Using stomata is arranged on roll surface, paper, example are generally fixed with negative-pressure adsorption for existing paper for daily use rewind roll
Such as CN201510400818.7, CN201711195372.4 patent application all refers to the production that paper is carried out by way of absorption
Processing.However, the arrangement of stomata will increase the preparation cost of equipment, and efficiency is not also high.It is badly in need of a kind of paper for daily use now
Rewind roll solves the above-mentioned problem.
Summary of the invention
In view of the deficienciess of the prior art, it is an object of that present invention to provide a kind of new paper for daily use rewind rolls, with solution
The problem that certainly traditional negative-pressure adsorption bring device structure is complicated, preparation cost increases, efficiency is not ideal enough.Specifically, this
Invention is to hold and fix the paper for daily use rewinding of paper for daily use by providing a kind of mainly by wear-resistant coating surface roughness
Roller is realized
One of the objects of the present invention is to provide a kind of paper for daily use rewind roll, including roll paper roller matrix, the roll papers
Roller matrix surface has sprayed composite coating, and the surface roughness of the composite coating is Ra6-30 μm.
Preferably, the surface roughness is Ra6-20 μm.
Further, the composite coating includes being selected from one or more of alloying pellet, wear-resistant ceramic particle.
Preferably, the alloy is selected from one or more of nickel-base alloy, ferrous alloy, cobalt-base alloys.
Preferably, the carbide or oxide ceramics for being 5-80% containing weight percent in the alloying pellet
Grain, the carbide are selected from one or more of tungsten carbide, chromium carbide, silicon carbide, and the oxide is selected from chromium oxide, oxidation
One or more of aluminium, silica, zirconium oxide.
Further, the composite coating with a thickness of 0.05-1.0mm.
The second object of the present invention is to provide a kind of preparation method of paper for daily use rewind roll, and the preparation method includes
Following steps:
(1) roll paper roller matrix is reached into dimensional accuracy by vehicle mill；
(2) oil removing sandblasting pretreatment is carried out to roll paper roller matrix；
(3) one layer of composite coating is sprayed in roll paper roller matrix surface.
Preferably, use granularity for the aluminium oxide of 24# or more, silica or iron when step (2) blasting treatment
Sand, blasting pressure 0.3-2.0MPa, by roll paper roller matrix surface sandblasting to roughness Ra 3-15um.
Preferably, spraying is thermal spraying in the step (3).
It further, after spray coating further include that sealing pores are carried out to composite coating.
It further, further include being removed the high point on composite coating surface and bulky grain with abrasive band or sand paper after sealing of hole.
The present invention has the following technical effect that compared with the existing technology
(1) paper for daily use rewind roll of the present invention coats composite coating in roller surface, including alloy and wear-resistant ceramic
Particle, and joined the carbide of constant weight ratio or oxide ceramics ingredient, wear-resisting property dramatically increase；It protects at work
Surface roughness is held in Ra6-20um, sharp and bulky grain does not pull paper for daily use to roll surface, and by prolonged operation
Roughness does not reduce, and is shutting down and the operating conditions lower roll such as humidity does not also get rusty or has an appearance of phenomena such as coating shedding.
(2) setting of paper for daily use rewinding roll surface roughness of the present invention, which can meet, grabs paper and fixed paper.And in roller matrix
When carrying out blasting treatment, thicker sand grains and pressure appropriate is selected to carry out sandblasting, in addition spraying the compound of upper appropriate granularity
Coating can enable final coating roughness reach Ra6-30um.
(3) present invention is after composite coating spraying, further progress sealing pores, can avoid roller matrix and is corroded,
To meet the requirement of various operating conditions.It is once polished again after sealing of hole simultaneously, the roughness of roll surface is dropped into Ra6-20um,
Paper for daily use is pulled to can avoid composite coating surface sharp bulky grain and protrusion.
(4) there are fiber attritions between paper for daily use and rewind roll, so having to wear-resisting composite coating just can solve
The requirement of rewind roll long-life under the conditions of high-speed automated.Because of roughness Ra 6-20um, if in the case where not wear-resisting, it is coarse
Degree decline is very fast, will have skidded fail to grip with paper after a period of use, be unable to satisfy the requirement of actual use.Thus originally
Carbide or ceramic oxide particle is added in invention in the alloy, can effectively solve the above problems.
(5) present invention joined the resistance to of ceramic particle in surface spray-coating using the method for thermal spraying with a thickness of 0.05-1.0mm
Composite coating is ground, the surface roughness of coating reaches Ra6-30um, and coating is final thick after sealing of hole and removal surface high point
Rugosity can meet the working condition requirement of high-speed domestic paper rewind roll to Ra6-20um in this way.
