Description

Technical Field

[0001] The invention relates to the technical field of printers, in particular to an intelligent transmission anti-collision mechanism for a UV flatbed printer. Background Art

[0002] UV printer is a high-tech full-color digital printing machine without plate making, which is not limited by materials. It can print color photos on T-shirts, sliding doors, cabinet doors, sliding doors, glass, plates, various signs, crystal, PVC, acrylic, metal, plastic, stone, leather and other surfaces. Since the print head has to move back and forth to print the printing material, there are the following problems:

[0003] 1. The surface of the workpiece is uneven: If the printer encounters an uneven surface of the workpiece during printing, the print head may be hit due to contact with the surface of the workpiece;

[0004] 2. Inaccurate printer calibration: If the printer is not calibrated correctly, the print head may collide with the workpiece or other parts when moving;

[0005] 3. External interference: Some external factors, such as operator negligence, equipment failure, etc., may also cause the print head to be accidentally hit.

[0006] When the above situation occurs, the print nozzle is prone to bumps and collisions, which may cause damage in severe cases. Even if there is no damage, the machine needs to be shut down for repair. During the repair, the UV ink inside the print nozzle will quickly solidify on the print nozzle after being exposed to light, causing blockage. Therefore, a UV printer is needed that can protect the print nozzle and clean the ink inside the print nozzle when it is hit. Summary of the invention

At this time, since the ink tube has been closed, the negative pressure generated in the second piston cylinder will cause the outside air to enter the containing box through the print nozzle, so that no ink remains in the print nozzle, preventing solidification and clogging.

[0041] The support plate 20 drives the second round rod 16 to rise and compresses the second spring 18. The second round rod 16 drives the round pin 15 to rise, and the round pin 15 will be separated from the limiting rod 17. At this time, the first spring 14 extends and pushes the squeezing rod 19 to squeeze the ink tube 13 to close it, so as to prevent the ink in the ink tube 13 from continuing to fall.

[0042] The pull plate 11 is pulled, and the pull plate 11 drives the squeezing rod 19 to move away from the ink tube 13 through the first round rod 12. The squeezing rod 19 drives the limiting rod 17 to move and compress the first spring 14.

[0044] When the second piston rod 24 is not squeezed by the squeezing block 25, the third spring 23 stretches out, pushing the second piston rod 24 to move toward the squeezing block 25, and the second piston rod 24 drives the second piston 2401 to move in the second piston cylinder 22. At this time, since the ink tube 13 has been closed, the negative pressure generated in the second piston cylinder 22 will cause the outside air to push the ink into the containing box 27 through the print head 7, so that no ink remains in the print head 7, preventing solidification and clogging;

[0045] When the second piston rod 24 is squeezed by the squeezing block 25, the third spring 23 is compressed, and at the same time, the second piston rod 24 drives the second piston 2401 to move in the second piston cylinder 22 to the side away from the squeezing block 25. At this time, since the ink has entered the containing box 27, the ink will not be pushed into the print head 7 to prevent clogging;

[0046] Further, such as Figure 1 As shown, a control panel 101 is installed on the outer wall of the support frame 1.

[0047] Working principle: Step 1: After connecting to an external power source, place the material to be printed on the support frame 1, control the slider 2 to drive the track 3 to move forward and backward through the control panel 101, and the printing support 4 drives the printing nozzle 7 to move back and forth through the first fixed frame 5 and the second fixed frame 6, so that the printing nozzle 7 prints the printing material;

[0048] Step 2: When the second fixed frame 6 encounters an obstacle, the obstacle will first squeeze the baffle 8, the baffle 8 drives the first piston rod 9 to move, the first piston rod 9 drives the first piston 901 to move in the first piston cylinder 10, at this time, the gas in the first piston cylinder 10 is compressed into the third piston cylinder 26, the third piston 2901 in the third piston cylinder 26 rises, the third piston 2901 drives the third piston rod 29 to rise, the third piston rod 29 drives the support plate 20 to slide upward in the slide groove 28, the support plate 20 drives the print head 7 to rise, and prevents the print head 7 from being hit;

[0049] Step 3: When the support plate 20 rises, the support plate 20 drives the second round rod 16 to rise and compresses the second spring 18. The second round rod 16 drives the round pin 15 to rise, and the round pin 15 will break away from the limiting rod 17. At this time, the first spring 14 extends and pushes the squeezing rod 19 to squeeze the ink tube 13 to close it, so as to prevent the ink in the ink tube 13 from continuing to fall.

[0050] Step 4: When the support plate 20 rises to close the ink tube 13, the solenoid valve 30 opens, the second piston rod 24 rises and no longer contacts the extrusion block 25, the third spring 23 stretches, pushes the second piston rod 24 to move toward the extrusion block 25, and the second piston rod 24 drives the second piston 2401 to move in the second piston cylinder 22. At this time, since the ink tube 13 has been closed, the negative pressure generated in the second piston cylinder 22 causes the outside air to enter the containing box 27 through the print head 7, so that no ink remains in the print head 7, preventing solidification and clogging;

[0051] Step 5: After the obstacle is handled, the second spring 18 contracts, driving the support plate 20 to descend in the slide groove 28, and the support plate 20 drives the print head 7 to descend to the initial position. At the same time, the support plate 20 drives the third piston 2901 to descend in the third piston cylinder 26 through the third piston rod 29, and the gas in the third piston cylinder 26 is compressed and enters the first piston cylinder 10. The first piston 901 in the first piston cylinder 10 is pushed to move toward the side of the baffle 8. The first piston 901 drives the baffle 8 to move through the first piston rod 9 and returns to the initial position;

[0052] At the same time, the support plate 20 drives the second piston cylinder 22 to descend, and the second piston cylinder 22 drives the second piston rod 24 to descend. The second piston rod 24 is squeezed by the squeezing block 25, compressing the third spring 23. At the same time, the second piston rod 24 drives the second piston 2401 to move in the second piston cylinder 22 to the side away from the squeezing block 25. At this time, since the ink has entered the containing box 27, the ink will not be pushed into the print head 7 to prevent clogging, and then the solenoid valve 30 is closed;

[0053] Step 6: After the print head 7 returns to the initial position, pull the pull plate 11 by hand. The pull plate 11 drives the squeezing rod 19 to move away from the ink tube 13 through the first round rod 12. The squeezing rod 19 drives the limiting rod 17 to move and compresses the first spring 14. The limiting rod 17 squeezes the round pin 15 and is then limited again. At this time, the ink tube 13 is opened and printing can be performed again.
