Description

Technical Field

[0001] The present invention relates to the technical field of printing technology, and more specifically, to a printing technology and equipment thereof. Background Art

[0002] Printing is a technology that allows the original text, pictures, photos, anti-counterfeiting and other manuscripts to be transferred to the surface of paper, textiles, plastics, leather, PVC, PC and other materials through processes such as plate making, inking and pressurization, so as to reproduce the original content in batches. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink.

[0003] For example, the authorization announcement number CN 215782975 U discloses a printing UV ink uniform mixing and stirring device. By pulling the handle, the connecting cover is threadedly connected to the mixing barrel, and the motor is started to drive the screw to rotate, so that the sleeve rod rotates synchronously. Due to the limiting effect of the limit rod, the sleeve rod moves up and down along the screw rod, thereby driving the friction plate at the bottom to rotate and slide up and down, so that the ink adhered to the side wall of the mixing barrel is swept into the mixing barrel to avoid adhesion. The outer rod cooperates with the slide groove and the through groove on the adjustment disk to change the inclination angle of the outer rod, and is fixed with bolts to clean different mixing barrel heights. The use of blocks also avoids slipping or collision.

[0004] In the above, although the mixing barrel can be cleaned, during use, it is necessary to manually pour the materials into the barrel, then transport the various colors of ink into the ink barrel, and finally stir them manually. Moreover, each person can only mix one color of ink at a time, which is inefficient. Summary of the invention

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0019] In the printing process, the first thing to do is to do platemaking, that is, to layout the prepared pages according to the printing order and format to form the pattern that needs to be printed on the product. Then, the plate is exposed and the film after platemaking is placed on the platemaking machine of the printing press. Through the steps of exposure and development, a printing plate that can be printed is made. A layer of photosensitive film is coated on the surface of the resin plate and then dried. The film with the image is covered on it. The film is irradiated with strong light, and the image on the film is exposed and photocopied onto the photosensitive film on the plate.

[0020] Then, according to the needs of the printing process, place the cardboard in the cutting machine and cut it into the required size. Finally, according to the color required for printing, place the ink raw materials under the automatic ink mixing machine, input the color mixing ratio into the PC end of the automatic ink mixing machine for color mixing.

[0021] In the color mixing process, an ink mixing machine is needed. First, place the ink raw material barrel on the placement station, then extend the extraction pipe into the raw material barrel, and enter the raw material ratio that needs to be mixed on the control panel 3.

[0022] Then, the cleaning bucket 10 and the receiving bucket are placed on the placement plate 23, and the receiving bucket and the cleaning bucket 10 are placed alternately. After the placement is completed, the hydraulic cylinder 24 is started to make the arc plate 25 contact the outer wall of the cleaning bucket 10 and fix the cleaning bucket 10 or the receiving bucket.

[0023] Then connect the feeding pipe 8 to the feeding port 6, and then rotate the receiving barrel to the uppermost position of the rotating frame 9 so that the receiving barrel can receive the ink. At the same time, the electric telescopic rod 17 is started to make the stirring rod 18 located in the receiving barrel. When the ink starts to be fed, the stepper motor 16 is started to drive the electric telescopic rod 17 and the stirring rod 18 to rotate, stir the ink in the receiving barrel, and make the color of the ink evenly mixed.

[0024] After stirring is completed, the electric telescopic rod 17 is reset. During the recovery process of the electric telescopic rod 17, the ink on the outer peripheral wall of the electric telescopic rod 17 will be scraped off. At this time, the hair dryer located on the inner wall of the box body 5 is started to blow off the ink on the electric telescopic rod 17 and the stirring rod 18. Subsequently, the rotating disk 12 continues to rotate to rotate the cleaning bucket 10 to below the stirring rod 18. The cleaning bucket 10 is pre-filled with water for cleaning the stirring rod 18. The electric telescopic rod 17 is started and extended into the cleaning bucket 10 for washing. After cleaning is completed, the electric telescopic rod 17 is reset. At this time, the hot air blower is started to dry the electric telescopic rod 17 and the stirring rod 18.

[0025] Finally, the rotating disk 12 continues to rotate, and the above operation is repeated to stir the next receiving barrel. When the stirred receiving barrel runs to the lowest point of the rotating disk 12, the cylinder 27 is started to lift the transfer plate 26. At this time, the transfer roller 28 on the transfer plate 26 is at the same horizontal plane as the receiving barrel. The receiving barrel is pushed to remove the prepared ink and replace it with a new receiving barrel.

[0026] Then install the prepared printing plate on the printing press, put the prepared ink into the printing press, adjust the parameters of the ink and paper, and start printing.

[0027] After printing, a layer of film is covered on the surface of the printed matter to increase the gloss and durability of the printed matter. Finally, according to the needs, embossing, folding, mounting, UV, embossing, gold and silver hot stamping printing processes can be carried out.
