Description

Technical Field

[0001] This invention relates to the field of printer technology, specifically to an antioxidant suction platform structure for a UV roll-to-roll printer. Background Technology

[0002] The anti-oxidation suction platform of a UV roll-to-roll printer is used to hold the roll material and provide stable suction. A UV roll-to-roll printer is a device specifically designed for printing on flexible materials, using UV curing technology. During the printing process, flexible materials such as soft film, leather, and wallpaper are prone to curling, causing friction between the material and the print head, affecting print quality. The anti-oxidation suction platform prevents curling and bubbling by adsorbing the roll material, ensuring stability in the printing process and excellent print results.

[0003] Chinese patent application number 202111482698.1 discloses a "suction platform structure for a guide belt type digital printing system for sheet metal", which includes a suction platform. The suction platform includes multiple suction zones, and the suction zones are connected to a suction fan through a suction structure. The suction structure includes multiple suction channels, which are arranged on the sides of adjacent suction zones, and adjacent suction zones are connected to the same suction channel.

[0004] When the printing material is being transported, the device can stably adsorb the printing material through the main suction area and the air leakage area. However, when transporting printing materials of different sizes, the adsorption area cannot be adjusted, which will cause air leakage in the areas not covered by the printing material and reduce the adsorption force. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-oxidation suction platform structure for a UV roll forming machine. This invention solves the problem that existing devices cannot automatically adjust the size of the adsorption area.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a UV roll-to-roll machine anti-oxidation suction platform structure, comprising a support frame, a printing nozzle located above the support frame, and a first and a second circular roller rotatably mounted on the support frame on both sides of the printing nozzle, and further comprising:

[0007] A conveyor belt, positioned below the print head, is used to transport printing material; the surface of the conveyor belt has several through holes.

[0008] The suction platform is located below the conveyor belt and uses through holes to adsorb the printing material above the conveyor belt.

[0009] A sealing component, disposed inside a through hole, includes a baffle and a retaining ring. A lead screw is installed on the upper surface of the baffle, and a first fan blade is installed on the outer wall of the lead screw. When the first fan blade rotates, it drives the lead screw to rotate, causing the baffle to descend and abut against the retaining ring, thus sealing the through hole.

[0010] The deceleration assembly, located above the enclosed assembly, includes several first fan blades, the first fan blades rotating at opposite angles to the second fan blades.

[0011] Preferably, the sealing assembly further includes a first support rod, which is slidably installed in the through hole through a groove opened on the outer wall of the through hole. A threaded sleeve is fixedly installed at the center of the first support rod, and the threaded sleeve is threadedly connected to the lead screw. A fifth round rod is slidably installed through the first fan blade on the side of the lead screw away from the baffle. A first gear is installed on the outer wall of the fifth round rod, and the outer wall of the retaining ring is installed on the through hole.

[0012] Preferably, the deceleration assembly further includes a support plate, the outer wall of which is mounted on a through hole, and the outer wall of the support plate has a plurality of ventilation holes. A second support rod is installed on the inner wall of the ventilation holes, and a fourth round rod is rotatably installed at the center of the second support rod. The upper end face of the fourth round rod is fixedly connected to the second fan blade, and a second gear is installed on the side of the fourth round rod away from the second fan blade.

[0013] Preferably, the outer wall of the support frame is equipped with a track, which is slidably connected to the print head.

[0014] Preferably, the inner wall of the conveyor belt is rotatably abutted against by a plurality of third round rods, one of which passes through the support frame at both ends and is fixedly connected to the first pulley and the output shaft of the servo motor respectively. The outer wall of the first pulley is fitted with a belt, and the inner wall of the belt away from the first pulley is fitted with a second pulley. The second pulley is the same size as the first pulley and is fixedly connected to the second round roller. The servo motor is mounted on the outer wall of the support frame.

[0015] Preferably, the suction platform is mounted on the inner wall of the support frame on both sides, the lower end of the suction platform is symmetrically connected to an exhaust fan, the lower end of the exhaust fan is connected to an exhaust platform, the exhaust platform is mounted on the inner wall of the support frame on both sides, and the lower end of the exhaust platform abuts against the conveyor belt.

[0016] Preferably, an electric telescopic rod is symmetrically installed on the outer wall of the support frame, and a second round rod is installed through the output end of the electric telescopic rod through the support frame. A disc is rotatably installed on the side of the second round rod away from the electric telescopic rod.

[0017] Preferably, a first round rod is rotatably mounted on the inner wall of the support frame.

[0018] Preferably, a control panel is installed on the outer wall of the support frame.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] I. This invention features a sealing component. The through-hole not covered by the printing material, due to strong winds, causes the second fan blade inside the vent hole on the support plate to rotate. The second fan blade drives the fourth round rod to rotate, which in turn drives the second gear to rotate. The second gear drives the first gear to rotate, which in turn drives the fifth round rod to rotate. The fifth round rod then drives the lead screw to rotate. Simultaneously, the wind within the through-hole also drives the first fan blade to rotate. Since the first and second fan blades rotate in opposite directions, the first fan blade and the fifth round rod simultaneously drive the lead screw to rotate within the threaded sleeve. The lead screw causes the baffle to descend. When the baffle abuts against the retaining ring, the through-hole closes. This enables automatic sealing of the area not covered by the printing material, automatically adjusting the size of the adsorption area to ensure adsorption strength.

[0021] II. This invention is equipped with a deceleration component. When the edge of the printing material covers part of the vent holes on the support plate, the second fan blade in the uncovered vent holes rotates, driving the fourth round rod to rotate. The fourth round rod drives the second gear to rotate, the second gear drives the first gear to rotate, the first gear drives the fifth round rod to rotate, and the fifth round rod and the first fan blade drive the lead screw to rotate. However, at this time, the upper end of the covered vent hole is closed, and the second fan blade in the vent hole is driven to rotate by the second gear. When the inside of the covered vent hole is rapidly drawn into a negative pressure by the second fan blade, the load on the second fan blade increases and the rotation speed decreases, thereby completing the deceleration of the lead screw, increasing the contact time between the baffle and the retaining ring, and keeping the through hole adsorbing the edge of the printing material.

[0031] Please see Figures 1 to 8 This invention provides a technical solution: an anti-oxidation suction platform structure for a UV roll forming machine, comprising a support frame 1, a printing nozzle 3 located above the support frame 1, and a first roller 4 and a second roller 8 rotatably mounted on the support frame 1 on both sides of the printing nozzle 3, and further comprising:

[0032] A conveyor belt 13 is disposed below the print head 3 and is used to transport the printing material 12. The surface of the conveyor belt 13 has a plurality of through holes 18.

[0033] The suction platform 21 is located below the conveyor belt 13 and adsorbs the printing material 12 above the conveyor belt 13 through the through hole 18;

[0034] A sealing component is provided inside the through hole 18, including a baffle 27 and a retaining ring 28. A lead screw 35 is installed on the upper end face of the baffle 27, and a first fan blade 24 is installed on the outer wall of the lead screw 35. When the first fan blade 24 rotates, it drives the lead screw 35 to rotate, causing the baffle 27 to descend and abut against the retaining ring 28, thus sealing the through hole 18.

[0035] The deceleration assembly is disposed above the enclosure assembly and includes a plurality of first fan blades 24, wherein the first fan blades 24 and the second fan blades 29 rotate at opposite angles.

[0036] Furthermore, such as Figure 5 , Figure 6 , Figure 7As shown, the enclosed assembly also includes a first support rod 26, which is slidably installed in the through hole 18 through a groove 25 opened on the outer wall of the through hole 18. A threaded sleeve 36 is fixedly installed at the center of the first support rod 26, and the threaded sleeve 36 is threadedly connected to the lead screw 35. A fifth round rod 31 is slidably installed on the side of the lead screw 35 away from the baffle 27 through the first fan blade 24. A first gear 33 is installed on the outer wall of the fifth round rod 31, and the outer wall of the retaining ring 28 is installed on the through hole 18.

[0037] The first support rod 26 drives the lead screw 35 to slide up and down in the slide groove 25 through the threaded sleeve 36. The lead screw 35 rotates in the threaded sleeve 36, driving the baffle 27 to move up and down. At the same time, the lead screw 35 drives the first gear 33 to rotate through the fifth round rod 31.

[0038] Furthermore, such as Figures 5 to 8 As shown, the deceleration assembly also includes a support plate 22. The outer wall of the support plate 22 is mounted on the through hole 18. The outer wall of the support plate 22 has a plurality of ventilation holes 23. A second support rod 32 is installed on the inner wall of the ventilation holes 23. A fourth round rod 30 is rotatably installed at the center of the second support rod 32. The upper end face of the fourth round rod 30 is fixedly connected to the second fan blade 29. A second gear 34 is installed on the side of the fourth round rod 30 away from the second fan blade 29. The second gear 34 meshes with the first gear 33.

[0039] When air is introduced into the vent 23, the second fan blade 29 inside rotates, which drives the fourth round rod 30 to rotate, and the fourth round rod 30 drives the second gear 34 to rotate.

[0040] Furthermore, such as Figure 1 As shown, a track 2 is installed on the outer wall of the support frame 1, and the track 2 is slidably connected to the print head 3;

[0041] The print head 3 moves back and forth on the track 2 to print on the printing material 12;

[0042] Furthermore, such as Figure 3 As shown, the inner wall of the conveyor belt 13 is rotatably abutted against by a plurality of third round rods 17. One of the third round rods 17 passes through the support frame 1 at both ends and is fixedly connected to the output shaft of the first pulley 9 and the servo motor 6 respectively. The outer wall of the first pulley 9 is fitted with a belt 10. The inner wall of the belt 10 away from the first pulley 9 is fitted with a second pulley 11. The second pulley 11 is the same size as the first pulley 9. The second pulley 11 is fixedly connected to the second round roller 8. The servo motor 6 is mounted on the outer wall of the support frame 1.

[0043] The servo motor 6 rotates, which drives the third round rod 17 to rotate. The third round rod 17 drives the conveyor belt 13 to rotate. At the same time, the third round rod 17 drives the first pulley 9 to rotate. The first pulley 9 drives the second pulley 11 to rotate through the belt 10. The second pulley 11 drives the second round roller 8 to rotate.

[0044] Furthermore, as shown in the figure, the suction platform 21 is installed on both sides of the inner wall of the support frame 1. The lower end of the suction platform 21 is symmetrically connected to the exhaust fan 20. The lower end of the exhaust fan 20 is connected to the exhaust platform 19. The two sides of the exhaust platform 19 are installed on the inner wall of the support frame 1. The lower end of the exhaust platform 19 abuts against the conveyor belt 13.

[0045] When the exhaust fan 20 is working, it draws air from the suction platform 21 to create negative pressure, drawing the gas into the exhaust platform 19 and discharging it.

[0046] Furthermore, such as Figure 3 As shown, electric telescopic rods 5 are symmetrically installed on the outer wall of the support frame 1. A second round rod 16 is installed through the output end of the electric telescopic rod 5 through the support frame 1. A disc 15 is rotatably installed on the side of the second round rod 16 away from the electric telescopic rod 5. A first round rod 14 is rotatably installed on the inner wall of the support frame 1. A control panel 7 is installed on the outer wall of the support frame 1.

[0047] The electric telescopic rod 5 extends or retracts, driving the second round rod 16 to move. The second round rod 16 drives the disc 15 to move, which can clamp printing materials 12 of different sizes.

[0048] Working principle: Step 1: First, the printing material 12 is placed on the first roller 4. The electric telescopic rod 5 is extended by the control panel 7. The electric telescopic rod 5 drives the second rod 16 to extend. The second rod 16 drives the disc 15 to abut against the printing material 12 to complete the positioning and prevent deviation.

[0049] Step 2: Activate the exhaust fan 20 via the control panel 7. At this time, the suction platform 21 begins to exhaust air from the conveyor belt 13 and controls the servo motor 6 to rotate. The servo motor 6 drives the conveyor belt 13 to rotate via the third round rod 17. The third round rod 17 drives the first pulley 9 to rotate. The first pulley 9 drives the second pulley 11 to rotate via the belt 10. The second pulley 11 drives the second roller 8 to rotate. Then, the printing material 12 is placed under the first round rod 14 and is attracted by the conveyor belt 13. The first round rod 14 quickly flattens the printing material 12. Because the conveyor belt 13 rotates, it moves the printing material 12 on the suction platform 21, making the conveying more stable.

[0050] Step 3: When the printing material 12 enters above the conveyor belt 13, the printing nozzle 3 operates, and simultaneously, the suction platform 21 adsorbs the printing material 12 through the through holes 18 on the surface of the conveyor belt 13. Figure 6 As shown, at this time, because the through hole 18 is covered and blocked by the printing material 12, the flow rate inside the through hole 18 is relatively slow. At this time, the second fan blade 29 in the vent hole 23 on the support plate 22 will not rotate, and the first fan blade 24 in the through hole 18 will not rotate either. The baffle 27 and the baffle ring 28 maintain a certain distance, which can achieve continuous adsorption of the printing material 12.

[0051] At the same time, such as Figure 7 As shown, the through hole 18 not covered by the printing material 12 will be blown by the strong wind, causing the second fan blade 29 in the vent hole 23 on the support plate 22 to rotate. The second fan blade 29 drives the fourth round rod 30 to rotate, the fourth round rod 30 drives the second gear 34 to rotate, the second gear 34 drives the first gear 33 to rotate, the first gear 33 drives the fifth round rod 31 to rotate, and the fifth round rod 31 drives the lead screw 35 to rotate. At this time, the wind in the through hole 18 will also drive the first fan blade 24 to rotate. Since the first fan blade 24 and the second fan blade 29 rotate in opposite directions, the first fan blade 24 and the fifth round rod 31 will simultaneously drive the lead screw 35 to rotate in the threaded sleeve 36. The lead screw 35 drives the baffle 27 to descend. When the baffle 27 abuts against the retaining ring 28, the through hole 18 is closed, which can realize the automatic sealing of the area not covered by the printing material 12, thereby automatically adjusting the size of the adsorption area.

[0052] When the printing material 12 covers part of the vent holes 23 on the support plate 22, the second fan blade 29 in the uncovered vent holes 23 rotates, driving the fourth round rod 30 to rotate. The fourth round rod 30 drives the second gear 34 to rotate, the second gear 34 drives the first gear 33 to rotate, the first gear 33 drives the fifth round rod 31 to rotate, and the fifth round rod 31 and the first fan blade 24 drive the lead screw 35 to rotate. However, at this time, the upper end of the covered vent holes 23 is closed. The second fan blade 29 in the vent holes 23 is driven to rotate by the second gear 34. When the inside of the covered vent holes 23 is quickly drawn into a negative pressure by the second fan blade 29, the load on the second fan blade 29 increases and the rotation speed decreases, thereby completing the deceleration of the lead screw 35, increasing the contact time between the baffle 27 and the retaining ring 28, so that the through hole 18 maintains the adsorption of the printing material 12 and allows it to pass smoothly through the printing nozzle 3.

[0053] Step 4: As the printing material 12 is conveyed by the conveyor belt 13, the printed material 12 is wound around the second roller 8. As the conveyor belt 13 rotates on the third rod 17, as... Figure 8As shown, the first support rod 26 in the through hole 18 slides in the groove 25. At this time, the baffle 27 separates from the retaining ring 28, and the air in the air outlet platform 19 flows out from the through hole 18. At this time, the first fan blade 24 reverses, and the first fan blade 24 drives the lead screw 35 to rotate in the threaded sleeve 36. The lead screw 35 drives the baffle 27 to continue to move away from the retaining ring 28. At the same time, the second fan blade 29 in the vent hole 23 will also drive the fourth round rod 30 to rotate. The fourth round rod 30 drives the second gear 34 to rotate. The second gear 34 drives the first gear 33 to rotate. The first gear 33 drives the lead screw 35 to rotate through the fifth round rod 31, accelerating the movement of the baffle 27, so that the baffle 27 returns to the initial position.
