BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate making machine, and more particularly, to a plate making machine capable of aligning a film and a printing plate in a convenient and accurate manner, and drying a printing plate coated with an emulsion film before making.

In general, a plate making machine is a technology of forming an image by printing the intensity of light into the intensity of current and printing a printed document.The gravure is applied by directly sculpting a plate after scanning the original with light spots, changing the intensity of current and processing it with a computer. Machines are in practical use. A color scanner is a device that scans color documents by color separation and outputs them in the negative or positive form of a photo without making a plate.

As illustrated in FIG. 1, the conventional plate making machine includes a control unit 11 on the front side of the main body 10 in which a light source such as an ultraviolet lamp is built, and an upper plate (on which a film and a plate is placed). 12) is fixedly installed.

And the upper side of the upper plate 12 is coupled to the cover 13 to be opened and closed around the hinge formed on the rear side.

Therefore, when the plate is made, the cover 13 is opened and the film and the printing plate are aligned on the top plate 12. At this time, the film is fixed to the top surface of the top plate 12 and the upper side of the fixed film. As the angle of the operator's eyes and the film and the printing plate does not form a right angle when the printing plate is fixed to the printing plate, problems such as not only accurate work of the film and the printing plate but also very inconvenient work were inherent.

In addition, the printing plate coated with the emulsion film in advance before the engraving process is to be dried in a separate plate dryer, which must be equipped with a separate plate dryer, so that problems such as narrowing place and cumbersome work and bonding the printing plate to the glass plate The problem was that the work was very difficult.

The present invention has been invented to solve the above problems, the object of the present invention is to make the film and the printing plate and the operator's eyes at right angles during engraving to ensure that the precise operation of the film and the printing plate is made and the operation is quick To provide a plate making machine structure that can be made and convenient.

Another object of the present invention is to provide a plate making machine structure that can be provided with a drying chamber integrally inside the plate making machine to dry the printing plate to increase the utilization of the space and improve the work productivity.

It is another object of the present invention to provide a plate making machine that can quickly and accurately couple a printing plate to a plate making machine.

The plate making machine according to the present invention for achieving the above object is a plate making machine for exposing by the light emitted from the ultraviolet lamp mounted inside the main body to perform the plate making, the upper side of the main body on the front side Rotating plate coupled to rotate about the hinge axis coupled is provided, the rear side of the rotating plate is provided with a cylinder hinged to the front end of the rod to be moved forward and backward in accordance with the operation to rotate the rotating plate at a predetermined angle, The lower side of the main body is characterized in that the drying chamber for drying the printing plate is completed.

Therefore, according to the present invention, the rotating plate is positioned at an angle perpendicular to the operator's eyes during engraving, so that the work of aligning the film with the printing plate is accurate and convenient, and therefore, the work speed is fast and the emulsion in the drying chamber formed at the lower side of the main body. The film-coated printing plate can be dried to minimize the worker's movement, increase the space utilization of the workplace, increase productivity, and make the printing plate fit on the glass plate quickly and accurately.

Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 2 is a side view illustrating the plate making machine according to the present invention, in which a plurality of ultraviolet lamps 21 for irradiating light to light are arranged inside the main body 20, and a control unit 22 is disposed on the front side thereof. Is provided.

And the upper fixing plate 23 is coupled to the upper side of the main body 20, the rotating plate 24 is coupled to the upper side of the upper fixing plate 23, the rubber material on the upper side of the rotating plate 24 The cover 25 formed as is coupled to open and close.

The rotating plate 24 is fixed to the glass plate 26 on the upper side so that the ultraviolet light emitted from the ultraviolet lamp 21 is irradiated.

In addition, the cover 25 is also configured such that the rear side is hinged to the hinge shaft 27 on the upper side of the rotating plate 24 to be opened and closed.

The back side of the main body 20 has a bracket 28 is formed protruding, the bracket 28 is configured so that the upper side of the cylinder 29 is hinged to the hinge shaft 30 is rotated at a predetermined angle, The tip of the rod 29a inserted into and retracted from the cylinder 29 is coupled to be rotated by the hinge shaft 31 and the rear side of the pivot plate 24.

And the cover 25 is provided with a buffer member 32 between the rotating plate 24, the front side of the rotating plate 24 is coupled to the hinge shaft 33 on the front side of the main body 20. It is.

The printing plate P is coupled to the upper side of the glass plate 26 via a film. The glass plate 26 is formed with an incision groove 26a formed at an upper predetermined position as shown in FIG. The female pin unit 34 is fixed in the 26a, and the male pin unit 35 is fixed to the printing plate P coupled to the upper side of the glass plate 26 opposite thereto.

The arm pin unit 34 is provided with a bracket 36 fixed to the rear surface of the glass plate 26 by means of an adhesive or the like, and the insertion hole 34a is provided in the arm pin unit 34 fixed to the bracket 36. It is formed at predetermined intervals.
