Description

Technical Field

[0001] The invention relates to a printing device, in particular to an inkjet mechanism of a digital printing machine. Background Art

[0002] In the prior art, the inkjet mechanism of a digital printing press includes a black inkjet mechanism and a color inkjet mechanism. The black inkjet mechanism and the color inkjet mechanism have the same width and move synchronously (the color inkjet mechanism cannot move relative to the black inkjet mechanism). The paper moves along the Y direction, and the inkjet mechanism reciprocates along the X direction. The inkjet mechanism of this digital printing press has the following disadvantages:

[0003] 1. When printing cartons and other packaging materials, the main information content is black, and only trademarks are in color. The utilization rate of color inkjet mechanisms is lower than that of black inkjet mechanisms. Long-term non-use can easily cause clogging of the color inkjet mechanism, requiring cleaning and maintenance of the color inkjet mechanism, which is time-consuming and labor-intensive.

[0004] 2. The width of the color inkjet mechanism and the black inkjet mechanism are equal, and the cost of the color inkjet mechanism is more expensive than that of the black inkjet mechanism, resulting in the high cost of the inkjet mechanism.

[0005] 3. The color inkjet mechanism and the black inkjet mechanism move synchronously. It often happens that in one reciprocating cycle of the inkjet mechanism, only one of the color inkjet mechanism or the black inkjet mechanism is working and the other is not working, resulting in low printing efficiency. Summary of the invention

[0006] In order to overcome the deficiencies of the prior art, the present invention provides a practical, low-cost and high-efficiency inkjet mechanism for a digital printing press.

[0007] The technical solution adopted by the present invention to solve the technical problem is:

[0014] The lifting power device comprises:

[0015] A power motor B is installed on the mobile carrier and is connected to the transverse screw rod B through a conveyor belt B;

[0016] The transverse screw rod B is hingedly mounted between the back plates;

[0017] A movable part is installed inside the transverse guide rail sleeve B, the sleeve of the movable part is sleeved on the transverse screw rod B and is threadedly connected thereto, and a pulley in contact with the lifting inclined surface is installed on the top of the movable part;

[0018] The transverse guide rail sleeve B is fixedly connected to the reinforcement strip.

[0019] The transverse connecting head sleeve of the movable part is slidably connected with the transverse guide rail outside the reinforcing strip.

[0020] The vertical guide rail head on the inner side of the back plate is sleeved on the vertical guide rail on the outer side of the vertical lifting plate and is slidably connected thereto.

[0026] The Y-direction movable panel is fixedly connected to the rectangular connecting piece and to the Y-direction guide rail head sleeved on the Y-direction guide rail, and the bottom is fixedly connected to the color inkjet mechanism.

[0027] The beneficial effects of the present invention are:

[0028] 1. The width of the color inkjet mechanism of the present invention is smaller than that of the black inkjet mechanism. The color inkjet mechanism is driven to move along the Y guide rail by the Y guide rail, thereby improving the utilization rate of the color inkjet mechanism.

The printing speed is more than doubled, the printing efficiency is high, and the production capacity can be improved accordingly. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The width of the color inkjet mechanism is smaller than that of the black inkjet mechanism. The color inkjet mechanism is driven to move along the Y guide rail through the Y guide rail, thereby improving the utilization rate of the color inkjet mechanism. Even if the width of the color inkjet mechanism is reduced, it can meet the work requirements and greatly reduce the cost of the inkjet mechanism.

[0038] The color inkjet mechanism is driven to move along the Y guide rail, thereby improving the utilization rate of the color inkjet mechanism, preventing the nozzle from being blocked, and saving time and effort in maintenance.

[0039] While the black inkjet mechanism is executing the printing operation of the black part, the color inkjet mechanism can also be moved to the appropriate printing position (with a detection device to detect whether it has reached the appropriate printing position) through the Y guide rail to execute the printing operation of the color part. The printing speed is more than doubled, the printing efficiency is high, and the production capacity can be improved accordingly.

[0040] Specifically, the lifting platform is located below the Y-direction guide rail.

[0054] During operation, the output shaft of the power motor B drives the transverse screw rod B to rotate through the conveyor belt B. The rotation of the transverse screw rod B can drive the movable parts to move forward and backward, and the pulley slides on the lifting inclined plane, so that the transverse lifting plate moves up and down, and the vertical lifting plate also moves up and down accordingly, so that the entire lifting platform moves up and down, thereby adjusting the distance between the inkjet bracket and the printed product (transmission mechanism) according to the thickness of the printed product.

[0055] The transverse connecting head 332 of the movable member 33 is sleeved on the transverse guide rail 125 outside the reinforcing strip 123 and is slidably connected thereto.

[0064] Specifically, there are two Y-direction guide rail heads 1321, and the two Y-direction guide rail heads 1321 and the rectangular connector 43 are arranged in a triangle, so the structure is very stable.

[0065] Specifically, the transverse screw rod B is located below the transverse screw rod A, and the transverse lifting plate 22 is located between the transverse screw rod A and the transverse screw rod B.

[0066] The inkjet mechanism is also provided with a conveying mechanism 91 , and the conveying mechanism 91 is located below the moving carrier 12 .
