Abstract

The present invention relates to a rolling shaft of a photographic paper printer and a manufacture method thereof. An inner layer of the rolling shaft is a root of a long circle rod; a layer of a resin, a layer of wearable powder particles and a layer of a resin are orderly arranged on the middle position of the long circle rod to the surface of the long circle rod in each set distance range away from both ends of the long circle rod from the interior to the exterior. The manufacture method mainly comprises the steps that both of the two ends of each long circle rod are sheathed with rubber sleeves; after the long circle rods sheathed with the rubber sleeves are horizontally arranged, one layer of a resin is sprayed on the long circle rod in order to form a rubber wheel in the middle position of the long circle rod; then, one layer of powder particle materials with the high friction coefficient are stuck on the surface of the rubber wheel. Thus, the rolling shaft has the better friction performance and can not generate chemical changes with photographic paper.

Description

The roller bearing of photographic paper form printer and manufacture method thereof

Technical field

The invention belongs to printing paper processing equipment and manufacture method thereof, particularly a kind of part of photographic paper form printer and manufacture method thereof.

Technical background

General known printer in order to the printing paper of prining, its inside is in order to transmit the roller bearing of printing paper, be that the mode with injection molding forms the rubber tire that one deck is made by elastomeric material on an oval bar, and because the chemical analysis complexity of this rubber rubber tire, the easy again variation because of temperature and time produces qualitative change, when the printing paper that has a chemical substance of photonasty or video picture when itself and surface contacts, then cause the surface that printing paper contacts with this rubber tire to produce chemical change easily, make image on the printing paper produce aberration or be stained with sticking with roller bearing and the influence quality of prining.

Moreover, the rubber tire of above-mentioned known roller bearing is by injection molding in the mould, on the periphery of rubber tire, can produce the spue line of twice symmetry, so must by the mode of grinding or cut the spue line on the rubber tire be removed again after this rubber tire penetrates and finishes, thereby when increasing worker and cost, processing is trouble inconvenience also.

The inventor is using and the disappearance of making thoughts on the transmission roller bearing of the known photographic paper form printer made from elastomeric material, thereby sets about the design research and development, designs a kind of roller bearing manufacture method of brand-new photographic paper form printer eventually.

Summary of the invention

Therefore, fundamental purpose of the present invention, aim to provide in a kind of photographic paper form printer in order to transmit the roller bearing and the manufacture method thereof of printing paper, this roller bearing internal layer is an oval bar, this oval bar interlude position is wear-resisting powder of one deck resin, one deck and another layer resin from this oval bar surface from inside to outside successively; This method is to spray a composition of layer comparatively to stablize, contact with printing paper merely the rubber tire that the resin that can not produce chemical change is the master on an oval bar surface, and make coarse that this roller surface becomes in wherein being stained with the glutinous irregular wear-resisting powder material of one deck, so that this roller bearing has preferable transmission friction force, and it contacts with printing paper and can not produce chemical change and improve its quality of prining.

The object of the present invention is achieved like this:

A kind of roller bearing of photographic paper form printer, its internal layer is an oval bar, it is characterized in that: in each set distance range of these oval bar two ends of distance, in this oval bar middle part,, from inside to outside, be wear-resisting powder of one deck resin, one deck and another layer resin successively from this oval bar surface.

This wear-resisting powder material can be ceramic powder or corundum.

A kind of method of making the roller bearing of above-mentioned photographic paper form printer may further comprise the steps at least:

(a) at the two ends of the oval bar of each root suit gum cover;

(b) on this oval bar, spray one deck resin, to form rubber tire in oval bar middle part;

(c) be stained with the glutinous wear-resisting powder material of one deck in the rubber tire surface that is formed on the oval bar;

(d) spray one deck resin again in being stained with on the glutinous oval bar that the powder material arranged, and treat that the resin of above-mentioned spraying after dry removes the gum cover at two ends, promptly finish the making of roller bearing.

Good effect of the present invention is: owing to adopt said structure and method, at the two ends of the oval bar of each root elder generation suit one gum cover, on this oval bar, spray one deck resin again, make this oval bar middle part form the rubber tire of a film like, again in rubber tire surface be stained with the glutinous wear-resisting powder material (as ceramic powder) of one deck thereafter, spray again at last and again gum cover is removed after one deck resin and wait are done, promptly finish the roller bearing of photographic paper form printer special use and make.It is the comparatively stable simple resin that can not produce chemical change that contacts with printing paper of chemical property that wherein oval bar sprays composition, and make this roller surface become coarse in wherein being stained with the glutinous irregular wear-resisting powder material of one deck, make this roller bearing have preferable transmission friction force, and contact with printing paper and can not produce chemical change and improve its quality of prining, therefore preferable result of use is arranged, its method for making is also extremely easy.

Rubber tire 3 resins 31

Powder material 4 roller bearings 10

Embodiment

At first consult Fig. 1 to Fig. 4, the present invention is made up of following step, now each step is described in detail as follows:

(a) earlier at the two ends of the oval bar 1 of each root suit gum cover 2, with the size of the diameter of keeping oval bar 1 two ends, and convenient follow-up processing (as shown in Figure 1);

(b) on this oval bar 1, spray the uniform resin film 31 of a layer thickness, so that this oval bar 1 forms 3 (as shown in Figure 2) of one deck rubber tire in the position therebetween;

(c) rubber tire 3 on above-mentioned oval bar 1 not dried before, be stained with the glutinous good powder material 4 (as: materials such as ceramic powder or corundum) of one deck wearing quality again in these rubber tire 3 surfaces, with can mat powder material 4 irregular surfaces and adhere to kenel, and make these roller bearing 10 surfaces have the effect (as shown in Figure 3) of high friction force;

(d) spray the uniform resin film 31 formation diaphragms of a layer thickness on oval bar 1 surface that powder material 4 is arranged in being stained with to stick again at last, so that powder material 4 can be prevented that powder material 4 from coming off in use by firm being coated in the resin bed; And the resin for the treatment of above-mentioned spraying removes the gum cover 2 at two ends after dry, promptly finishes the making of roller bearing 10, as shown in Figure 4.

According to above-mentioned manufacture method, since the rubber tire 3 on this oval bar 1 be with chemical constitution stablize, simple resin material makes, thereby this rolls opinion and 10 is pressed against when transmitting on the printing paper, produce chemical change when being avoided rubber tire 3 surfaces directly to contact with printing paper, influence the quality of prining so can prevent printing paper from producing chemical change, therefore preferable result of use is arranged.

Moreover, because this rubber tire 3 coats the irregular wear-resisting powder material 4 of one deck in 31 in two-layer tree fat, make the surface of rubber tire 3 have preferable friction force so that transmit printing paper.
