Description

Technical Field

[0001] The invention relates to the technical field of printing equipment, in particular to a food packaging box surface printing device. Background Art

[0002] A printing device is a device that transfers the ink of the image on the printing plate to the paper. Color printing is a method of copying images or text in color. It includes many steps, or conversion processes, to produce high-quality color copies. The color separation process is used to digitally scan the original and separate the original into red, green and blue components. Before the development of digital imaging, the traditional method of color separation was to photograph the image three times, each time using a color filter of the corresponding color to filter different light. However, after the color separation, the desired result is 3 gray images, which represent the red, green and blue components of the original. The next step is to convert each color separation film. When generating a negative image of the red component, the generated image represents the cyan component of the image. Similarly, Negative images of the green and blue components are also generated in order to generate magenta and yellow separations accordingly. Cyan, magenta and yellow are subtractive primary colors, because each color represents the two additive primary colors remaining after subtracting an additive primary color from white light. Cyan, magenta and yellow are the three main pigments in color reproduction. When these three colors are combined in printing, the original can be reasonably reproduced. However, this is not the case in reality. Due to the limitations of ink pigments, the darker colors produced are dirtier and smudged. In order to solve this problem, a black plate must be made to improve the color of the dark part and enhance the contrast of the image. There are already a variety of technologies that can make this black plate from the original image, including gray component replacement, background color removal and background color addition.

[0003] The prior art has a simple structure and reasonable design. It prints plastic products through two sets of roller brushes, so that the coating can be printed more fully. The printing pattern on the plastic product can be changed by changing the roller brush. The heating device heats it, and then the hot air is blown by the blower, which increases the speed of air flow and is more conducive to drying the printed matter. However, it is difficult to drive the packaging box to move forward by itself, and it is difficult to print in color on packaging boxes of different thicknesses, so that the scope of use of the device is narrow and difficult to market. It is difficult to change the movement speed of the packaging box on the transmission mechanism by changing the inclination angle of the transmission mechanism, and it is difficult to adjust the transmission speed of the packaging box according to demand. Therefore, those skilled in the art provide a food packaging box surface printing device to solve the problems raised in the above background technology. Summary of the invention

[0030] A transmission mechanism 6 is provided at one end of the operating table 1, and a trolley 7 is provided at one end of the transmission mechanism 6. The transmission mechanism 6 includes a transmission roller 61, an inner plate 62, a nut 63, an outer plate 64, a rotating shaft 65, a supporting bottom plate 66 and a third spring 67. A transmission roller 61 is provided inside the transmission mechanism 6, and both ends of the transmission roller 61 are rotatably connected to the inner plate 62, one end of the inner plate 62 is threadedly connected to the nut 63, and the front side of the inner plate 62 is slidably connected to the outer plate 64, one end of the inner plate 62 is welded with a stud, and the inner plate 62 is provided inside There is a groove, and the nut 63 is connected to the stud by a thread, one end of the transmission roller 61 is rotatably connected to the groove, one end of the outer plate 64 is rotatably connected to the support base plate 66, and a rotating shaft 65 is rotatably connected between the outer plate 64 and the support base plate 66.

By adjusting the distance between the inner plate 62 and the outer plate 64, the inclination angle of the transmission mechanism 6 can be changed, thereby changing the movement speed of the packaging box on the transmission mechanism 6, and the transmission speed of the packaging box can be adjusted according to needs.

[0031] The working process and working principle of the present invention are as follows: when it is necessary to perform color printing on a packaging box, first place the packaging box on the leftmost end of the operating table 1, then turn on the control switch 11 to allow the motor 212 to start working normally, and the motor 212 drives the connecting shaft 25 to rotate through the belt 211, and the connecting shaft 25 drives the first feed roller 26 to rotate, and similarly, the second feed roller 27 is driven by another motor to rotate. The difference is that due to the different rotation directions of the two motors, the first feed roller 26 rotates counterclockwise, and the second feed roller 27 rotates clockwise. When the packaging box is placed in the middle of the first feed roller 26 and the second feed roller 27, due to the first feed roller The reverse rotation of the first feed roller 26 and the second feed roller 27 drives the packaging box to move forward automatically without manual operation. When the thickness of the packaging box is too large, the packaging box will compress the first feed roller 26 and the second feed roller 27. At this time, the first feed roller 26 and the second feed roller 27 will compress the first spring 22 and the second spring 29 respectively, so that the first spring 22 and the second spring 29 shrink and become shorter. The feeding mechanism 2 can adapt to packaging boxes of different thicknesses. When the packaging box moves to the inside of the printing chamber 3, the printing chamber 3 performs color printing on the packaging box. After printing is completed, the packaging box continues to move forward due to the reverse rotation of the first feed roller 26 and the second feed roller 27. When the packaging box moves to the inside of the drying mechanism 4 When the packing box is in the state of being transported to the storage tank 1, the packing box 2 is put into the storage tank 1 by the conveyor belt 2. When the packing box is in the state of being transported to the storage tank 1, the conveyor belt 2 is not required to transport the packing box ... Moreover, they will be arranged neatly, and the staff does not need to sort the packaging boxes anymore. They only need to transport the printed packaging boxes to the warehouse. In addition, the moving speed of the packaging boxes can be controlled by adjusting one end of the transmission mechanism 6. When the transmission rate needs to be adjusted, the staff first rotates the nut 63 to loosen the inner plate 62 and the outer plate 64. At this time, the inner plate 62 and the outer plate 64 are adjusted to the appropriate position, and then the inner plate 62 and the outer plate 64 are tightly combined together by rotating the nut 63. Since the transmission mechanism 6 is in a tilted state, the elastic action of the third spring 67 can keep the supporting bottom plate 66 in a horizontal state at all times, and will not tilt with the tilt of the transmission mechanism 6.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
