Description

Printing device for package printing Technical Field The utility model relates to the technical field of package printing, in particular to a printing device for package printing. Background Printing devices are machines that print text and images. Modern printing devices generally consist of mechanisms such as plate loading, inking, stamping, paper feeding (including folding), and the like. The printing plate is made of characters and images to be printed, and is installed on a printing device, then the printing device is used for coating ink on the places where the characters and images are on the printing plate, and then the ink is directly or indirectly transferred onto paper or other printing stock (such as textile, metal plate, plastic, leather, wood plate, glass and ceramics), so that the printed matter identical to the printing plate can be copied. In the process of packaging food, some patterns or characters need to be printed on the packaging bag of food, so that a printing device for packaging printing is needed. The existing printing device for packaging printing generally cannot visually monitor the use condition of ink when the food packaging is printed, and can supplement the ink after the printing device cannot be used normally, so that the printing operation of the printing device is seriously delayed, and the printing efficiency is reduced. Disclosure of utility model Based on the above, the utility model aims to provide a printing device for package printing, so as to solve the technical problem that the existing printing device for package printing cannot timely supplement ink and influences the service efficiency. In order to achieve the above purpose, the printing device for packaging printing comprises a base, wherein a U-shaped frame is arranged on one side of the top of the base, a storage barrel is arranged on the top of the U-shaped frame, a material distributing barrel is arranged in the storage barrel, a material supplementing mechanism is arranged in the material distributing barrel, the material supplementing mechanism comprises a vertical rod, a moving plate is arranged at the bottom of the vertical rod, a spring is sleeved on the outer side of the vertical rod, printing ink is contained at the bottom of the moving plate, and a connecting pipe is arranged at the bottom of the material distributing barrel. By adopting the technical scheme, when printing is continuously performed, the ink is continuously consumed, the movable plate continuously moves downwards along with the ink liquid level and pushes the ink to be supplemented into the printing head through the connecting pipe, and the vertical rod can be smoothly driven to move downwards by the downwards movement of the movable plate. Further, one end of the connecting pipe, which is far away from the material distributing cylinder, is provided with a printing head, the printing head is provided with a supporting plate, and the top of the supporting plate is fixedly connected with an electric push rod. Through adopting above-mentioned technical scheme, the setting of backup pad can provide stable support to the print head, ensures that the print head can normally carry out the printing operation. Further, a transmission mechanism is arranged below the printing head, and an air hole is formed in the transmission mechanism.
