Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printing equipment, in particular to a waterless printing equipment and method thereof. BACKGROUND

[0002] At present, printing technology is mainly divided into traditional printing and waterless printing. Traditional printing needs to coat a layer of water film on the template, so a large amount of water resources will be wasted in the long use process. Waterless printing makes the photosensitive polymer and the silica gel layer separate at the joint through exposure, so that the ink is adsorbed on the photosensitive polymer and is repelled by the silica rubber layer.

[0003] The waterless printing machine in the related art comprises a machine box, a paper loading box, a temperature control system, an exposure system and an ink loading system. The paper loading box, the temperature control system, the exposure system and the ink loading system are arranged in the machine box. Before use, the machine box is opened, the paper is loaded into the paper loading box, the temperature control system keeps the printing machine at a constant temperature during printing, the printing plate is exposed at the exposure system and then is sent to the ink loading system for ink loading, and then the ink is printed on the paper.

[0004] According to the related art, after the paper is printed, the paper needs to be reloaded by opening the machine box, putting in the paper and closing the machine box. The ink used in waterless printing is waterless ink, which has high viscosity and generates large friction when the ink roller is ground, thereby increasing the temperature in the printing machine and affecting the printing effect.

[0005] In the related art, the machine box needs to be opened every time the paper is used up and the paper is loaded. Opening the machine box will destroy the temperature balance in the machine box, so after the paper is loaded, the printing work needs to be performed after the temperature control system adjusts the temperature of the machine box to be constant, thereby wasting time in the printing process. SUMMARY

[0006] The purpose of the present application is to provide a waterless printing equipment and method thereof which can save printing time.

[0007] In the first aspect, the waterless printing equipment provided by the present application adopts the following technical scheme: a waterless printing equipment, comprising: a waterless printing machine, a conveying belt and a plurality of storage devices, wherein the plurality of storage devices are arranged on the conveying belt;

[0008] A plurality of supporting openings are formed in the conveying belt, and one supporting opening is arranged below each storage device.

[0028] During mechanical operation, the contact is in a continuous power-on state, and the contact is exposed to the air, so users are easy to contact the contact and cause electric shock, by adopting the technical scheme, the contact is arranged in the protection cover, when the box cover contacts the protection cover, the protection cover is pushed to move into the receiving groove, and the contact is exposed, and then the contact is inserted into the power connection port. The protection cover covers the contact, reducing the direct contact between the user and the contact, thereby reducing the risk of electric shock of the user.

[0029] Optionally, a limiting plate is fixedly connected to the output end of the first lifting member, a limiting groove is formed in the bottom surface of the paper loading box, and the limiting groove is matched with the limiting plate;

[0030] The conveying belt is provided with a plurality of limiting protrusions, and each two limiting protrusions are symmetrically arranged relative to the limiting groove.

[0031] In the process that the first lifting member pushes the carton to move upward, the carton is prone to be toppled, and the carton is also prone to be toppled in the process of being transported by the conveying belt; by adopting the above technical scheme, the limiting protrusion plays a limiting role on the carton in the process of being transported by the conveying belt, thereby reducing the possibility of the carton being toppled; in the process that the carton moves upward, the limiting plate is inserted into the limiting groove to limit the carton, thereby reducing the possibility of the carton being toppled.

[0032] Optionally, the paper outlet is provided in the shape of a neck, and the caliber of the paper outlet is greater than the width of the paper.

[0033] In the process that the paper moves upward, the paper may be deviated; by adopting the above technical scheme, the paper outlet corrects the paper when the paper passes through the paper outlet, so that the paper is aligned with the paper inlet.

[0034] Optionally, a sliding groove is formed in the top surface of the box cover, and the sliding groove is in communication with the power connection opening;

[0038] The side surface of the sliding block is downwardly inclined and provided with a guide inclined surface.

[0039] In daily work, the power connection opening is always exposed to the air, and the power connection opening is prone to accumulate dust, thereby causing poor contact between the power connection opening and the contact; by adopting the above technical scheme, before the power connection opening contacts the contact, the sliding block shields the power connection opening, thereby reducing the possibility of the power connection opening accumulating dust. When the protective cover contacts the sliding block, the sliding block moves in the sliding groove under the guidance of the guide inclined surface until the power connection opening is exposed, and then the contact is inserted into the power connection opening.
