Description

Technical Field

[0001] The utility model belongs to the technical field of label printing, and more specifically, relates to a die-cutting device for label printing. Background Art

[0002] The widespread use of labels and the continuous development of label varieties have naturally driven the development of label printing technology. Label printing encompasses all printing methods, including flat, convex, debossed, and screen printing, and its application varies from country to country. However, recent global label development trends indicate that flexographic printing, narrow web printing, and digital printing have become new highlights and development trends in label printing in Europe and the United States.

[0003] Application No. CN202223219736.7 The utility model discloses a die-cutting device for label printing, which relates to the field of label printing technology and includes a main body, a device frame is provided at the front end of the main body, a die-cutting conveying platform is installed on the lower side of the inner cavity of the main body, a limiting wheel frame is provided on both sides of the inner cavity of the device frame, a positioning device is installed on one side of the limiting wheel frame, a translation adjustment device is installed on the inner upper end of the device frame, an electric lifting rod is provided in the middle of the translation adjustment device, and a die-cutting tool holder is installed at the bottom end of the electric lifting rod. The utility model is arranged on the inner side of the limiting wheel frame through a fixed frame. When in use, the driving motor in the frame is powered on and started, and then the threaded rod at the lower end of the driving bin is driven by the coupling to rotate clockwise. The reverse thread inside the threaded cross seat penetrating the threaded rod moves downward during rotation, thereby driving the pressure rod and the positioning plate to adjust according to the thickness of the label, facilitating the die-cutting tool holder to cut.

[0004] Based on the search of the above patents and the application of existing label printing die-cutting devices, it is understood that when label printing is introduced into the die-cutting link, if the label body is displaced, it will cause the label die-cutting to be dislocated and damaged, and it cannot be used. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a die-cutting device for label printing to solve the problem that in the existing label printing, if the label body is displaced during the die-cutting process, the label will be dislocated and damaged, making it unusable.

[0006] The purpose and function of the die-cutting device for label printing of the present invention are achieved by the following specific technical means:

[0007] 7. The swiftly and minutely adjusting device for a wood-planer working table as claimed in claim 1, wherein said linking rod and said adjusting base are pivotally connected to each other with a bolt, and said bolt has a round shank to contact with said linking rod.

[0008] According to an embodiment of the present invention, a support assembly is respectively provided at the four corners of the bottom of the die-cutting equipment frame, and the support assembly consists of height-adjustable support legs and universal wheels.

[0009] According to one embodiment of the present invention, the top position of the die-cutting equipment frame is fixedly connected to a material rack, the inner position of the material rack is rotatably connected to a label roller, and the label roller is located above the rear end of the guide frame.

[0010] According to an embodiment of the present invention, a through hole is formed in the middle of the bottom of each sliding frame, and an adjusting bolt is rotatably connected in the through hole of the sliding frame.

[0011] According to an embodiment of the present invention, a threaded hole is respectively opened at the outer position of the top of the two sliding roller frames, and the adjustment bolt is inserted into the threaded hole of the sliding roller frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Place the label roller on the material rack, and then use the label roller to pass the label to be printed in the middle position of the two sliding roller racks and the fixed roller rack. Turn the adjusting bolt to adjust the two sliding roller racks to slide on the inner position of the sliding rack. The distance between the sliding roller rack and the fixed roller rack will be adjusted to facilitate the position limit processing of the thickness of the printed label and adapt to the position limit of labels of different thicknesses. When the label passes through the middle position of the sliding roller rack and the fixed roller rack, the rollers of the sliding roller rack and the fixed roller rack will rotate, which will not cause wear to the label.

[0014] In addition, the motor's shaft will drive the reverse screw to rotate, and the distance between the two sliding frames will be adjusted to adapt to the width position of the label to prevent the label from being misaligned during the die-cutting process. BRIEF DESCRIPTION OF THE DRAWINGS
