Description

Technical Field

[0001] The utility model relates to printing equipment, in particular to a stacked printing mechanism. Background Art

[0002] A stacked printing machine is a common printing device. Its structure mainly stacks printing units on both sides of a frame plate to achieve multi-color printing of a printing substrate. For example, a Chinese patent document (Publication No.: CN206749227U; Publication Date: December 15, 2017) discloses a stacked multi-color printing machine. Referring to its drawings and specifications, it can be seen that its printing pressure rollers are all arranged on the frame plate, and a single motor drives one of the pressure rollers, and then different drive belt groups are used to drive each pressure roller to rotate. The defect of this structure is that all the pressure rollers are driven and linked through the drive belt groups. In the actual printing process, according to the changes in printing requirements, the printing times required for both sides of the printing substrate are not the same. When the printing surface changes, it is necessary to control the pressure rollers to reverse. At this time, most of the synchronous belt drive groups need to be re-wound to ensure the rotation direction of each pressure roller. However, the number of synchronous belts for driving each pressure roller is very large, the winding method of the synchronous belts is extremely complex, and the adjustment operation is very troublesome, time-consuming and laborious. Content of the Utility Model

[0003] In view of the deficiencies of the background art, the technical problem to be solved by the present utility model is to provide a stacked printing mechanism for solving the above problems.

[0004] To this end, the present utility model is implemented as follows:

[0005] A stacked printing mechanism has a frame plate. A left stacked printing group is arranged on the left side of the frame plate, and a right stacked printing group is arranged on the right side. It is characterized in that: the left stacked printing group includes at least two left printing units arranged up and down. The left pressure roller in each left printing unit is rotatably arranged on the frame plate. At least one left pressure roller is connected to the output end of a corresponding first motor, and the remaining left pressure rollers are connected to any one of the actively rotatable left pressure rollers through corresponding drive belt groups. The right stacked printing group includes at least two right printing units arranged up and down. The right pressure roller in each right printing unit is rotatably arranged on the frame plate. At least one right pressure roller is connected to the output end of a second motor, and the remaining right pressure rollers are connected to any one of the actively rotatable right pressure rollers through corresponding drive belt groups.

[0006] There are three left printing units arranged vertically. The left pressure roller in the middle position is connected to the output end of the first motor. There are three right printing units arranged vertically. The right pressure roller in the middle position is connected to the output end of the second motor.

[0007] A stacked printing mechanism of the above technical solution, with left and right stacked printing groups arranged on both sides, and at least one printing pressure roller of the printing units of each stacked printing group being driven by a corresponding motor, and then driving other pressure rollers of the corresponding stacked printing group to rotate through a transmission belt group. By adopting this structure of driving the pressure rollers on both sides actively, each pressure roller on each side can be directly connected to the corresponding active pressure roller through a relatively independent transmission belt group. This driving method can effectively reduce the number of transmission synchronous belts and simplify the winding method of the synchronous belts. When it is necessary to control the corresponding pressure roller to perform steering adjustment, only the corresponding transmission belt group needs to be replaced, while the transmission belt groups of other pressure rollers do not need to be replaced, making the rotation adjustment operation of the pressure rollers simpler.

[0008] The present utility model has the following drawings:

[0009] Figure 1 It is a schematic structural view of the present utility model;

[0010] Figure 2 is Figure 1 a view from another perspective. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0011] As shown in the figure, a stacked printing mechanism disclosed by the present utility model has a frame plate 1. A left stacked printing group is arranged on the left side of the frame plate 1, and a right stacked printing group is arranged on the right side. Each printing unit has a cooperating pressure roller, plate roller 4, anilox roller 5, and ink cartridge 6. Specifically, the left stacked printing group includes at least two left printing units arranged vertically. The left pressure roller 3 in each left printing unit is rotatably arranged on the frame plate 1. At least one left pressure roller 3 is connected to the output end of the first motor 11, and the remaining left pressure rollers 3 are connected to any one of the left pressure rollers that can rotate actively through corresponding transmission belt groups. The right stacked printing group includes at least two right printing units arranged vertically. The right pressure roller 8 in each right printing unit is rotatably arranged on the frame plate 1. At least one right pressure roller 8 is connected to the output end of the second motor 12, and the remaining right pressure rollers 8 are connected to any one of the right pressure rollers that can rotate actively through corresponding transmission belt groups. In this embodiment, three left printing units are arranged vertically. The left pressure roller 3 in the middle position is connected to the output end of the first motor 11. The left pressure roller 3 in the middle position is connected to the lower left pressure roller through the first synchronous belt transmission group 2, and the left pressure roller 3 in the middle position is connected to the upper left pressure roller through the second synchronous belt transmission group 7 to realize the transmission of each pressure roller in the left stacked printing group. Three right printing units are arranged vertically. The right pressure roller 8 in the middle position is connected to the output end of the second motor 12. The right pressure roller 8 in the middle position is connected to the upper right pressure roller through the third synchronous belt transmission group 9, and the right pressure roller 8 in the middle position is connected to the lower right pressure roller through the fourth synchronous belt transmission group 10. By changing the winding and structure of the first, second, third, and fourth synchronous belt transmission groups, the rotation direction of the corresponding pressure roller can be changed. With a printing mechanism of this structure, various combination printing methods such as 0:6 (printing 0 colors on the front and 6 colors on the back, the same applies hereinafter), 1:5, 2:4, 3:3, 4:2, 5:1, 6:0 can be used, and its application range is very wide.

[0012] For this stacked printing mechanism of the present utility model, left and right stacked printing groups are arranged on both sides. At least one printing pressure roller of the printing units in each stacked printing group is driven by a corresponding motor, and then the other pressure rollers in the corresponding stacked printing group are driven to rotate through the transmission belt group. With this structure of driving the pressure rollers on both sides actively, each pressure roller on each side can be directly connected to the corresponding active pressure roller through a relatively independent transmission belt group. This driving method can effectively reduce the number of transmission synchronous belts and simplify the winding method of the synchronous belts. When it is necessary to control the corresponding pressure roller to adjust the rotation direction, only the corresponding transmission belt group needs to be replaced, and the transmission belt groups of other pressure rollers do not need to be replaced, making the rotation adjustment operation of the pressure roller simpler.
