Description

Technical Field

[0001] This utility model relates to the field of photocuring technology, and more specifically, to a photocuring device with cooling and shaping function. Background Technology

[0002] Playing cards, high-end packaging, book covers, and other printed materials often require surface varnishing to enhance their appearance and improve their wear and water resistance. Currently, anilox roller varnishing is the mainstream precision quantitative varnishing technology. It uses an anilox roller to carry the varnish, and a doctor blade removes the excess, transferring a fixed amount of varnish from the cells to the surface of the substrate.

[0003] In traditional equipment, after the varnish is injected into the cavity, air is easily mixed in due to flow impact and agitation, forming microbubbles. If these bubbles are not effectively removed, they will be transferred with the varnish to the cells of the anilox roller or directly coated onto the surface of the printed material, ultimately leading to defects such as pinholes, pitting, and uneven gloss in the varnish layer, significantly reducing the product's appearance pass rate. Therefore, we propose a varnish curing device with cooling and setting functions. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a curing device with cooling and shaping functions to solve the technical problem that air bubbles are easily mixed into the current varnish injection cavity, resulting in defects in the varnish layer.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a varnish curing device with cooling and shaping, including a fixed bracket, a first conveying device at the top of the fixed bracket, a defoaming mechanism at the top of the first conveying device, and an auxiliary mechanism for cooperating in completing the defoaming of the varnish inside the defoaming mechanism. The defoaming mechanism includes an anilox roller, a trapezoidal frame, and a rotating roller. The rotating roller is rotatably installed inside the trapezoidal frame, and part of the anilox roller is located inside the trapezoidal frame. The rotating roller has spirally distributed defoaming teeth on its surface. The auxiliary mechanism includes an elastic scraper and defoaming spikes. The elastic scraper is fixedly installed inside an installation groove at the bottom of the trapezoidal frame, and defoaming spikes are provided on the inner side of the elastic scraper facing the anilox roller.

[0006] Preferably, the defoaming mechanism further includes a fixing frame, which is fixedly installed on the top of the fixing bracket. A motor is fixedly installed on the outside of the fixing frame, and a first synchronous pulley is fixedly installed at the output end of the motor. The first synchronous pulley is coaxially fixedly installed with the anilox roller, and a second synchronous pulley is drivenly installed on the outside of the first synchronous pulley. The second synchronous pulley is coaxially connected to the rotating roller through a sealed bearing.

[0007] Preferably, the auxiliary mechanism further includes a fixing plate, which is fixedly installed inside the mounting groove. A plurality of elastic blades are fixedly installed at the bottom of the fixing plate, and the free ends of the elastic blades abut against the back of the elastic scraper.

[0008] Preferably, the rotating roller is arranged parallel to the anilox roller.

[0009] Preferably, the cross-section of the trapezoidal frame is an inverted trapezoid, with its top width being greater than its bottom width, and the top of the trapezoidal frame is also provided with an oil inlet and an exhaust valve.

[0010] Preferably, the elastic blade has an arc-shaped structure, and several elastic blades are stacked along the length direction of the elastic scraper.

[0011] Preferably, the device further includes a cooling and shaping device and a second conveying device, wherein the second conveying device is disposed at the discharge end of the first conveying device and the cooling and shaping device is disposed above the second conveying device.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes spirally distributed defoaming teeth on the surface of the rotating roller. When rotating, the tips of the teeth exert a strong shearing effect on the varnish, which can efficiently tear and cut bubbles. The strong axial flow generated by the spiral structure forces the varnish to rush towards the surface of the anilox roller. This process not only promotes the breakage of bubbles but also enhances the flow of varnish. Defoaming spikes are set on the inner side of the elastic scraper to perform secondary puncture on the varnish after primary defoaming, removing residual microbubbles and avoiding coating defects caused by bubbles. This ensures the flatness and smoothness of the varnished surface and solves the problem that bubbles are easily mixed into the varnish injection cavity, leading to defects in the varnished layer.

[0013] 2. This invention also utilizes the spiral defoaming teeth on the surface of the rotating roller to generate a powerful axial flow while breaking bubbles. This axial flow forces the varnish onto the surface of the anilox roller and impacts the cell entrances at a specific angle and speed, achieving active filling of the cells instead of relying on the natural flow of the varnish. This active filling method greatly improves the filling efficiency and integrity of the anilox roller cells, ensuring that each cell is fully loaded with varnish. This results in a uniform and consistent varnish coating on the playing card surface, improving both the gloss stability of the topcoat and the wear resistance and protective performance of the varnish layer.

[0016] Example: Figures 1 to 6 As shown, this utility model relates to a varnish curing device with cooling and shaping function, including a fixed support 1, a first conveying device 11 on the top of the fixed support 1, a defoaming mechanism 2 on the top of the first conveying device 11, an auxiliary mechanism 3 for assisting in defoaming the varnish inside the defoaming mechanism 2, a cooling and shaping device 4, and a second conveying device 12. The second conveying device 12 is located at the discharge end of the first conveying device 11, and the cooling and shaping device 4 is located above the second conveying device 12. The defoaming mechanism 2 includes an anilox roller 23, a trapezoidal frame 24, and a rotating roller 25. The cross section of the trapezoidal frame 24... The surface is an inverted trapezoid with a top width greater than the bottom width. The top of the trapezoidal frame 24 is also provided with an oil inlet 241 and an exhaust valve 242. The rotating roller 25 is rotatably installed inside the trapezoidal frame 24. Part of the roller body of the anilox roller 23 is set inside the trapezoidal frame 24. The rotating roller 25 is arranged parallel to the anilox roller 23. The surface of the rotating roller 25 is provided with spirally distributed defoaming teeth 26. The auxiliary mechanism 3 includes an elastic scraper 34 and defoaming spikes 35. The elastic scraper 34 is fixedly installed inside the mounting groove 31 opened at the bottom of the trapezoidal frame 24. The inner side of the elastic scraper 34 facing the anilox roller 23 is provided with defoaming spikes 35.

[0017] Furthermore, the defoaming mechanism 2 also includes a fixed frame 21, which is fixedly installed on the top of the fixed support 1. A motor 211 is fixedly installed on the outside of the fixed frame 21, and a first synchronous pulley 22 is fixedly installed at the output end of the motor 211. The first synchronous pulley 22 is coaxially fixedly installed with the anilox roller 23, and a second synchronous pulley 222 is drivenly installed on the outside of the first synchronous pulley 22. The second synchronous pulley 222 is coaxially connected to the rotating roller 25 through a sealed bearing. In this invention, the spirally distributed defoaming teeth 26 on the surface of the rotating roller 25 defoam when rotating... The toothed tip exerts a strong shearing effect on the varnish, which can efficiently tear and cut air bubbles. At the same time, the strong axial flow generated by the spiral structure forces the varnish to rush towards the surface of the anilox roller 23. This process not only promotes the breakage of air bubbles, but also enhances the flow of varnish. Defoaming spikes 35 are set on the inner side of the elastic scraper 34 to puncture the varnish that has undergone primary defoaming a second time, thoroughly removing residual microbubbles. This avoids coating defects caused by air bubbles, ensures the smoothness and flatness of the varnish surface, and solves the problem that air bubbles are easily mixed into the varnish injection cavity, resulting in defects in the varnish layer.

[0018] Furthermore, the auxiliary mechanism 3 also includes a fixing plate 32, which is fixedly installed inside the mounting groove 31. Several elastic blades 33 are fixedly installed at the bottom of the fixing plate 32. The free ends of the elastic blades 33 abut against the back of the elastic scraper 34. The elastic blades 33 have an arc-shaped structure, and several elastic blades 33 are stacked along the length of the elastic scraper 34. The stacked elastic blades 33 support the elastic scraper 34. When the anilox roller 23 moves closer or further away due to jumping, the elastic blades 33 can undergo elastic deformation, absorb impact energy and continuously provide restoring force, so that the scraper blade edge can always stably track the roller surface.

[0019] Working Principle: This embodiment provides a curing device with cooling and shaping function. In use, playing cards are placed at the position of the first conveying device 11 on top of the fixed support 1 for conveying. After the playing cards are conveyed to the position of the anilox roller 23, external varnish is injected into the trapezoidal frame 24 through the oil inlet 241. The fixed motor 211 is started, and the output end of the motor 211 drives the first synchronous pulley 22 to rotate. The rotation of the first synchronous pulley 22 drives the second synchronous pulley 222 to rotate via the synchronous belt 221, thereby causing the rotating roller 25 and the anilox roller 23 to rotate synchronously. When the rotating roller 25 rotates, the defoaming teeth 26 distributed on the surface of the rotating roller 25 cut the air bubbles in the varnish, thus performing a defoaming operation. When the tips of the teeth 26 rotate at high speed, they exert a strong shearing force on the flowing varnish. The liquid film of the bubbles is stretched and torn under the strong shearing force, thus rupturing. Because the threads of the defoaming teeth 26 are distributed on the surface of the rotating roller 25, the strong axial flow generated is equivalent to actively filling the cells on the surface of the anilox roller 23. The varnish is forced to the surface of the anilox roller 23 and impacts the cell entrance at a certain angle and speed, which greatly improves the filling efficiency and integrity, ensuring that each cell is fully loaded with varnish. In addition, during the rotation of the rotating roller 25, the defoaming teeth 26 can push the oil to the side wall of the trapezoidal frame 24, and then the defoaming spikes 35 set on the inner side of the elastic scraper 34 can puncture the oil a second time, increasing the defoaming efficiency.

[0020] When the high-speed rotating anilox roller 23 experiences slight fluctuations due to processing precision, its surface periodically approaches or moves away from the elastic scraper 34. When the surface of the anilox roller 23 approaches, the pressure increases, pressing against the elastic scraper 34. The elastic scraper 34 transmits the force to the elastic vane 33, which undergoes elastic deformation to absorb impact energy and avoid hard collisions. When the surface of the anilox roller 23 moves away, the pressure decreases, and the elastic restoring force of the trapezoidal frame 24 lifts the elastic scraper 34, causing it to continuously track the surface of the anilox roller 23 and maintain stable contact pressure. The scraper then applies minimal pressure to the surface of the anilox roller 23, thoroughly removing all excess varnish outside the cells, thus enabling the polishing operation on the playing cards.

[0021] After the varnishing is completed, the playing cards are conveyed by the first conveyor 11 into the second conveyor 12, so that the playing cards enter the cooling and shaping device 4 for cooling and shaping.
