Description

Dull and stereotyped anticollision institution of printing of panel

Technical Field

The utility model belongs to the technical field of decorative plate processing, and particularly relates to a flat-plate printing anti-collision mechanism for a plate.

Background

In the prior art, decorative plates based on materials such as PVC and the like are widely applied. During production, the following modes can be adopted: processing a functional layer on a PVC substrate, printing a plane pattern on the surface of the functional layer by adopting a flat printer, and further stacking/curing transparent glue or oil at a specific position on the surface of a plate by adopting the flat printer to prepare a 3D effect.

In the actual production process, due to the characteristics of the PVC substrate, the PVC substrate has warping deformation, although the proportion is not large, when the flat-bed printing is carried out, the warped substrate can damage and scratch the ink-jet head of the flat-bed printing machine due to the close distance between the ink-jet head of the flat-bed printing machine and the plate. In the operation, in order to protect the ink jet head, the deformation substrate needs to be sorted out before the station where the flat-panel printer is located, and the deformation substrate is ironed and flattened.

Disclosure of Invention

In order to solve the technical problem, the utility model modifies the plate feeding part of the existing flat printing, and specifically comprises the following steps:

a flat-plate printing anti-collision mechanism for plates comprises a rack, a conveying belt and a flat-plate printer shell; the conveying belt is arranged on the frame; the conveying belt is partially arranged in the flat-bed printer shell, and the position of an ink-jet head in the flat-bed printer shell is above the conveying belt; the front end and the rear end of the flat-plate printer shell are respectively provided with a plate inlet and a plate outlet, and the moving path of the conveying belt is arranged between the plate inlet and the plate outlet.

Through holes are densely distributed on the conveying belt; the wind box is arranged on the frame, is arranged between the forward path and the return path of the conveying belt, and is arranged between the driving roller and the driven roller of the conveying belt; the top surface of the air box is densely provided with through holes, and the air box is connected with an air extractor through an air pipe.

The principle of the mechanism is that the substrate is absorbed to the surface of the belt through negative pressure (negative pressure gas absorbs the substrate through holes on the top surfaces of the conveying belt and the air box), the warped part is restored to be flat, and ink-jet printing is carried out. In practical engineering, the plates are stacked in the storage and transportation process, and the warped plates can be flattened without affecting the final assembly and use. The air extracting device can adopt an air extracting pump and the like, and an air outlet of the air extracting pump can be connected with an air storage cylinder to be used as compressed air required by other equipment in the production process.

As an improvement: the top surface of the air box is also connected with a supporting mechanism of a conveying belt. The support mechanism can avoid friction between the conveyor belt and the top face of the bellows.

Specifically, the method comprises the following steps: the supporting mechanism is a plurality of parallel supporting rollers, and each supporting roller is arranged on the top surface of the bellows;

or the supporting mechanism is a plurality of universal balls, and each universal ball is arranged on the top surface of the air box and is in an array structure.

One way is as follows: the top surface of the air box is provided with a plurality of concave parts, and the shape of the concave parts corresponds to the shape of the supporting roller; the main body of each supporting roller is arranged in the corresponding inner recess, and the top surface of each supporting roller is exposed out of the top surface of the air box; two ends of a roll shaft of the supporting roller are respectively connected to the frame through a bearing mechanism.

In another mode: the top surface of bellows has a plurality of indents, and each universal ball is installed in corresponding indent, and the top of universal ball exposes in the top surface of bellows.

In both modes, the recess may be free of through holes. The supporting rollers and the universal balls are exposed to a small degree on the top surface of the bellows, and only the conveying belt is not contacted with the risk top surface.

Further improvement: the plate inlet and the plate outlet are both connected with dust-proof curtains; the coverage range of the top surface of the air box is larger than the range between the plate inlet and the plate outlet.

Because of the negative pressure air suction device, in order to avoid the influence of the micro dust on the printing process, the dust blocking curtains are arranged at the positions of the plate inlet and the plate outlet.

The dust blocking curtain can be a brush structure formed by a plurality of rubber strips, and air can enter the dust blocking curtain and can block dust. The rubber strip is hung on the surface of the conveying belt. The soft rubber strip does not cause the sheet to shift because the sheet is sucked on the surface of the conveyor belt by the negative pressure from the bellows. The flat-bed printer uses UV ink which is cured by UV lamp irradiation, and the ink is cured on the plate at the plate outlet, so that the soft rubber strip does not influence the pattern on the plate.

Further improvement: the air box is characterized in that a plurality of connectors connected with the air pipes are uniformly distributed on the left side surface and the right side surface of the air box. Under this structure, make the atmospheric pressure of each through-hole of bellows comparatively balanced.

After the mechanism is adopted to carry out equipment transformation on the existing flat-bed printer, the collision of the warping plate to the ink gun can be better avoided.
