Abstract

The invention discloses a ceramic tile printing machine which comprises a moving work bench, a printing drum and an ink-applying device. The machine further comprises a transfer-printing drum arranged in parallel to the printing drum. The transfer-printing drum is contacted with the circumferential surface of the printing drum. In the invention, the glazing material is printed onto the surface of the ceramic tile by the transfer-printing drum. The transfer-printing process has no strict requirement for contact pressure and suits the thickness error of the ceramic tile, thereby ensuring printing quality without damaging the ceramic tile. The surface of the transfer-printing drum is not etched for printing, and kept smooth to facilitate the washing and cleaning operations. The printing drum is not directly contacted with the ceramic tile, so that the printing drum can be made of high-strength hard materials, thereby prolonging the service life thereof.

Description

Ceramic tile printing machine

Technical field

The present invention relates to a kind of ceramic machinery, particularly relate to a kind of machine for ceramics glazing and printed patterns.

Background technology

Chinese invention patent CN94118976.7 discloses " a kind of rotary machine that is used for glazing and decoration ", it comprises a traverser that is made of travelling belt, the top of worktable is provided with a rotatable version forming roll tube, version forming roll tube is made of central core, intermediary elastic layer and the peripheral version type layer of inside, wherein the surface of version type layer is provided with a lot of small holes, and the inking device that is made of feed pipe and scraping blade can be filled in glaze in these holes.When contacting when the rotation of version forming roll tube and with synchronization-moving ceramic tile surface on the worktable, the glaze in the hole will be stamped on the ceramic tile, forms pattern.Because what adopt is the intaglio printing mode, therefore version forming roll tube must contact with ceramic tile with certain pressure, certain deformation takes place on version type surface just can and transfer to ceramic tile surface with the extruding of the glaze in the hole, if contact pressure is too little, then can't guarantee printing quality; If contact pressure may be damaged ceramic tile by pressure too greatly again.Yet the thickness error of ceramic tile itself is bigger, though the elastic layer that version forming roll tube is provided with can play certain effect that remedies, is difficult to guarantee suitable contact pressure between version forming roll tube and the ceramic tile, thereby is difficult to guarantee printing quality.

The ceramic printing machine that adopts the letterpress mode is also arranged, though relief printing plate is lower to the requirement of contact pressure, relief printing plate often exists the defective that the glazing amount is little, work-ing life short and cleaning is difficult.

Summary of the invention

The technical problem to be solved in the present invention provides the ceramic tile printing machine of a kind of printing quality height, long service life.

In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of ceramic tile printing machine, comprise traverser, version forming roll tube and inking device, also comprise a transfer printing roller with the parallel installation of described version forming roll tube, described transfer printing roller contacts with edition circumferential surface of forming roll tube.

Preferably, the circumferential surface of described transfer printing roller is a smooth surface, comprises that also a cleaning scraper contacts with the circumferential surface of transfer printing roller.The smooth surface of transfer printing roller is convenient to clean, thereby can guarantee the sharpness of printing continuously.

Preferably, the version type on the described version forming roll tube is an intaglio plate.

Further, described version forming roll tube is made by the hard corrosion resistant material.Thisly make gravure roller by the hard corrosion resistant material, wear-resistant, corrosion-resistant, can increase the service life greatly; And can bear bigger contact pressure, guarantee the effect of transfer printing.

Preferably, described transfer printing roller is connected with transmission mechanism respectively with a version forming roll tube and relative to rotating synchronously.

The invention has the beneficial effects as follows: because glaze is to be transferred to the lip-deep of ceramic tile by the transfer printing roller, this transfer printing is very little to the requirement of contact pressure, can adapt to the thickness error of ceramic tile preferably, can guarantee printing quality, can not damage ceramic tile again.The surface of transfer printing roller does not need to cut blocks for printing, and can be smooth surface, cleans up easily; Therefore version forming roll tube can adopt high-intensity mechanically resistant material to cut blocks for printing and make because directly do not contact with ceramic tile, and prolong work-ing life greatly.

Description of drawings

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.

Fig. 1 is the structural representation of ceramic tile printing machine of the present invention.

Embodiment

As shown in Figure 1, traverser 1 is made of travelling belt, and version forming roll tube 2 is installed in the top of traverser 1, and a version forming roll tube 2 can be made by hard corrosion resistant materials such as stainless steels, and the surface engraves pattern by modes such as electricity carving or corrosion, forms intaglio plate.The inking device that is made of ink supply pipe 3 and last black scraper 4 can be filled into glaze in edition pit on forming roll tube 2 surfaces.

Transfer printing roller 5 is a rubber roll, has certain elasticity, it and edition parallel installation of axis of forming roll tube 2.Transfer printing roller 5 contacts with the circumferential surface of version forming roll tube 2 and is connected with transmission mechanism respectively, can realize relative to rotating synchronously.When transfer printing roller 5 contacted and relatively rotates with certain pressure with version forming roll tube 2, the glaze in version forming roll tube 2 surface craters can be transferred the surface that roller 5 is drawn to transfer printing roller 5.

Ceramic tile 7 moves with traverser 1, when moving to the below of transfer printing roller 5, ceramic tile 7 contacts with transfer printing roller 5, and they are identical in the linear velocity of point of contact, glaze on the transfer printing roller 5 just is transferred to the surface of ceramic tile 7 like this, because glaze is original just attached to the surface of transfer printing roller 5, rather than in pit, therefore the process of this transfer printing does not need great contact pressure, certainly in order to adapt to the thickness error of ceramic tile, transfer printing roller 5 also needs the certain elastic deformation ability.Though version forming roll tube 2 is inflexible, it can directly not contact with ceramic tile 7.

With transfer printing roller 5 surfaces after ceramic tile 7 contacts in rotation process can with clean scraper 6 and contact, the residual glaze on surface can be eliminated totally, and then contacts with version forming roll tube 2 and to obtain new glaze, so goes round and begins again.Because the surface of transfer printing roller 5 through cutting blocks for printing, is not a smooth surface, can be cleaned scraper 6 at an easy rate and scrape totally, thus the sharpness that assurance is repeated print.
