Description

Technical Field

[0001] The present invention relates to the technical field of digital printing, and in particular to a digital printing device and a digital printing process. Background Art

[0002] A printing press is a machine used to print text and images. The working principle is as follows: the text and image to be printed are first made into a printing plate and mounted on the printing press. Ink is then applied to the areas of the plate where the text and image are located, either manually or by the printing press. The ink is then directly or indirectly transferred to paper or other substrates (such as cardboard, metal plates, plastic, leather, wood, glass, and ceramics), creating a printed product identical to the printing plate. This is also true for printing on plate materials.

[0003] According to a digital printing device disclosed (Announcement No.: CN217050814U), in the above application, a conveyor belt for transporting substrates is provided on one side of the workbench, and a pushing mechanism for pushing the substrates to the conveyor belt after they are sorted is provided on the other side of the workbench, wherein the clamping assembly clamps and aligns the substrate, the second driving member drives the slide plate to move up and down while driving the clamping assembly to move up and down together, the first driving member pushes the slider to move, so as to drive the clamping assembly to move together and push its substrate to the conveyor belt, so that the conveyor belt can transport the substrate after clamping and aligning, thereby avoiding the situation where the substrate is offset during the transportation of the conveyor belt.

[0004] However, in actual use, although the above-mentioned equipment can clamp and align the printing material through the clamping assembly, it only relies on a single clamping arm for positioning, which limits the positioning angle and level, and the correction effect is not good when a large number of sheets are stacked. In view of this, we propose a digital printing device and a digital printing process. Summary of the Invention

The inner wall of the movable plate is provided with a passage groove, and the side wall of the touch pressure inclined plate is fixedly connected to the L-shaped transmission rod, the end portion of the L-shaped transmission rod is fixedly connected to the multi-section telescopic plate, the outer wall of the multi-section telescopic plate is fixedly connected to the touch pressure block, the inner wall of the clamping plate is provided with a touch pressure groove, the inner wall of the touch pressure groove is fixedly connected to the limiting rod, the outer wall of the limiting rod is slidably connected to the outer wall of the multi-section telescopic plate, the inner wall of the touch pressure groove is slidably connected to the sliding block, and the end portion of the sliding block is fixedly connected to the extrusion tough plate 2.

[0010] Preferably, the limiting groove 1 is configured to be wavy in shape, so that when the clamping plate moves laterally, the sliding rod connected to the shifting inclined plate will perform a wavy displacement in the limiting groove 1.

[0011] Preferably, the toggle plates are provided in two groups, and the two groups of toggle plates are provided in an "eight" shape, so that the toggle plates are provided in an "eight" shape to perform a toggle centering operation on the touch plate.

[0012] Preferably, the end of the touch inclined plate is movably connected to the bottom end of the base plate, and the touch inclined plate periodically touches the base plate, so that the base plate can be lifted periodically, thereby making the plate centered and moved forward on the base plate fit the front plate.

[0013] Preferably, the sliding grooves are provided in a plurality, and the plurality of sliding grooves are arranged in a linear array on the outer surface of the sandwich panel.

[0014] Preferably, the protective positioning components are provided in two groups, and the two groups of protective positioning components are mirror-imaged on both sides of the center plane of the front plate, so that smooth transmission can be performed and the extruded flexible plate 1 and the extruded flexible plate 2 can fix the plate.

[0015] Preferably, the inclined surface of the contact and pressure inclined plate is movably connected to the outer wall of the extrusion tough plate.

[0016] The present invention also proposes a digital printing process, which includes the following steps:

[0017] S1. Place the sheet material on the base plate, start the digital transmission printing chamber, and start the transmission component;

[0018] S2. Start motor 1 to rotate threaded rod 1 clockwise, so that threaded slider 1, which is restricted by the fixing sleeve, is lifted to an appropriate height. Then start the cylinder to lift the base plate and the mounting frame. At this time, start motor 2 to rotate the bidirectional threaded rod clockwise, so that threaded slider 2, which is restricted by limiting plate 1 on the bidirectional threaded rod, moves towards each other, thereby driving the clamping plate to move closer to the center.

[0019] S3. When the clamping plates move toward the center, the plates are centered. When the clamping plates move laterally, the sliding rod connected to the toggle plate moves in a wave-like manner in the limiting groove 1, so that the toggle plate is arranged in an "eight" shape to toggle the contact plate to the center.

[0020] S4. When the toggle plate is moved in an "eight" shape to center the touch plate, the touch plate periodically touches the bottom plate, causing the bottom plate to be periodically lifted, thereby attaching the plate centered and moved forward on the bottom plate to the front plate;

[0021] S5. When the plate is touched for positioning, the electric push rod is activated to drive the elastic expansion plate and the contact pressure plate on the connecting plate to move, so that the moving angle of the guiding plate can be adjusted more finely. After the guiding is completed, the contact pressure plate will be no longer restricted by the limiting plate 2 and will be retracted into the sliding groove due to the squeezing force, so that the plate can be positioned and brought closer smoothly.

[0022] S6. After the sheet is edged, the motor can be started to rotate the threaded rod counterclockwise, causing the threaded slider, which is restrained by the fixed sleeve, to descend to a suitable height, so that the transmission assembly can move the sheet at the bottom of the bottom plate forward, thereby allowing the sheet to enter the digital transmission printing chamber for printing.

[0023] S7. When one sheet material is transferred out of the bottom plate and the front plate, the sheet material presses the contact pressure ramp and the rubber pad to rise, thereby causing the spring on the inner wall of the movable groove to stretch, so that the extrusion plate one clamps and positions the front end of the sheet material that is about to fall and be discharged. In addition, the contact pressure block at the end of the multi-section telescopic plate is synchronously raised by the transmission of the L-shaped transmission rod, so that the contact pressure block pushes the extrusion plate two forward, so that the extrusion plate two positions and clamps the rear of the sheet material.

[0024] S8. Only when the entire plate is discharged can the upper plate be dropped, without causing the plate to tilt and fall, resulting in inaccurate positioning. The transmission component can accurately position and transmit the plate that has been positioned multiple times, so that the digital transmission printing chamber can complete accurate positioning printing.

[0025] Compared with the prior art, the present invention provides a digital printing device and a digital printing process, which have the following beneficial effects:

[0026] 1. The digital printing device and digital printing process start the second motor to rotate the bidirectional threaded rod clockwise, so that the second threaded slider on the bidirectional threaded rod, which is restricted by the first restriction plate, moves toward each other, so that when the clamping plate moves toward the center, the plate is centered and moved together, and when the clamping plate moves laterally, the sliding rod connected to the toggle plate is displaced in a wave shape in the first restriction groove, so that the toggle plate is arranged in an "eight" shape to toggle and center the touch plate. When the toggle plate is arranged in an "eight" shape to toggle and center the touch plate, the touch plate periodically touches the bottom plate, so that the bottom plate can be periodically lifted, thereby attaching the plate centered and moved forward on the bottom plate to the front plate.

[0027] 2. This digital printing device and digital printing process, when the plate is touched for positioning, activates the electric push rod to drive the elastic expansion plate and the contact pressure flexible plate on the connecting plate to move, thereby being able to more finely adjust the movement angle of the guiding plate, and after the guidance is completed, the contact pressure flexible plate will be no longer restricted by the limiting plate 2 and will shrink to the sliding groove due to the extrusion force, thereby allowing the plate to be positioned smoothly.

[0028] 3. In the digital printing device and digital printing process, when a sheet material is transmitted out of the bottom plate and the front plate, the sheet material will press the contact pressure inclined plate and the rubber pad to rise, thereby stretching the spring on the inner wall of the movable groove, so that the extrusion flexible plate pair clamps and positions the front end of the sheet material that is about to fall and be discharged, and through the transmission of the L-shaped transmission rod, the contact pressure block at the end of the multi-section telescopic plate rises synchronously, so that the contact pressure block pushes the extrusion flexible plate two to move forward, so that the extrusion flexible plate two positions and clamps the rear of the sheet material, so that the upper sheet material can only be dropped when the entire sheet material is discharged, without causing the sheet material to tilt and fall, resulting in inaccurate positioning.

A digital printing process according to any one of claims 1 to 6, characterized in that: The printing process comprises the following steps: S1, stacking the plate on the bottom plate (522), starting the digital transmission printing chamber (3), and starting the transmission component (4); S2, start the motor 1 (505) to rotate the threaded rod 1 (506) clockwise, so that the threaded slider 1 (507) restricted by the fixed sleeve (504) is lifted to a suitable height, and then start the cylinder (502), the bottom plate (522) and the mounting frame (508) are lifted, and then start the motor 2 (511) to rotate the bidirectional threaded rod (509) clockwise, and the threaded slider 2 (510) restricted by the limiting plate 1 (515) on the bidirectional threaded rod (509) runs in opposite directions, driving the clamping plate (513) to move closer to the center; S3, when the clamping plate (513) moves toward the center, the plate is centered and moved together, and when the clamping plate (513) moves laterally, the sliding rod (518) connected to the toggle plate (514) is caused to perform a wave-shaped displacement in the limiting groove 1 (516), thereby causing the toggle plate (514) to be set in an "eight" shape to perform a toggle and center operation on the touching plate; S4, when the inclined plate (514) is moved in an "eight" shape to center the touch plate, the touch inclined plate (519) will periodically touch the bottom plate (522), and the bottom plate (522) can be periodically lifted, and the plate centered and moved forward on the bottom plate (522) is attached to the front plate (523); S5. When the plate is touched for positioning, the electric push rod (602) is activated to drive the elastic expansion plate (604) and the contact pressure plate (605) on the connecting plate (603) to move. After the guidance is completed, the contact pressure plate (605) is no longer restricted by the second restriction plate (606) and will shrink to the sliding groove (601) due to the extrusion force, and the plate is positioned and brought closer together smoothly. S6. After the plate is moved to the edge, the motor 1 (505) is started to rotate the threaded rod 1 (506) counterclockwise, and the threaded slider 1 (507) restricted by the fixed sleeve (504) is lowered to a suitable height. The transmission component (4) can move the plate at the bottom of the bottom plate (522) forward, and the plate can enter the digital transmission printing chamber (3) for printing. S7. When a plate is transmitted out of the bottom plate (522) and the front plate (523), the plate will press the contact inclined plate (705) and the rubber pad (706) to rise, the spring (702) on the inner wall of the movable groove (701) will stretch, and the first extrusion tough plate (703) will clamp and position the front end of the plate that is about to fall and be discharged, and through the transmission of the L-shaped transmission rod (708), the contact block (710) at the end of the multi-section telescopic plate (709) will rise synchronously, and the contact block (710) will push the second extrusion tough plate (714) to move forward, and the second extrusion tough plate (714) will position and clamp the rear of the plate.
