Description

Technical Field

[0001] This invention relates to the field of pencil coating equipment technology, specifically to the water-based skin-feel pencil coating process and specialized equipment. Background Technology

[0002] Water-based skin-feel pencil paint (also called water-based skin-like textured pencil paint) is a special environmentally friendly water-based coating designed specifically for pencil body coating. Using water as the main dispersion medium, it is the final topcoat for pencil barrel coating. While meeting the protective and decorative needs of pencil coating, it achieves a smooth and skin-friendly grip feel. It is a core upgraded coating material for high-end stationery such as student pencils and colored pencils, and it is also the mainstream development direction of water-based and low-VOC coatings in the pen manufacturing industry.

[0003] When applying water-based skin-feel paint to pencils, the pencil is often passed through the paint box at high speed to allow the paint to evenly soak the pencil surface. Skin-feel paint contains a large amount of elastic resin to achieve a soft touch, which results in poor adhesion. Furthermore, when the pencil moves quickly, the contact time between the skin-feel paint and the pencil is short, which may make it difficult for the skin-feel paint to fully soak the pencil surface and affect the even application of the skin-feel paint. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a water-based skin-feel pencil paint application process and dedicated equipment. The water-based skin-feel pencil paint application process includes the following steps: Step 1: Using a feeding device, pencils are continuously and rapidly fed into the paint chamber one after another. The pencils will pass through the paint chamber at high speed. Step 2: As the pencil passes through the paint cavity, the paint will come into contact with the pencil and adhere to the pencil surface. Step 3: As the pencil continues to move, it will come into contact with the scraper head, which will scrape off the excess paint from the pencil surface, forming a thin coating and completing the painting process.

[0005] Preferably, the specialized equipment for water-based skin-feel pencil paint application includes a paint collection box. The paint collection box has three inlets on its inner left side and three outlets on its inner right side. The central axis of each of the three inlets is aligned with the central axis of the three outlets. The paint cavity refers to the paint collection box. The equipment also includes: The painting mechanism is fixedly installed on the left side of the outer wall of the paint collection box; The hedging mechanism is installed on the inner wall of the paint collection box; The bonding mechanism is fixedly installed on the inner wall of the counter-clamping mechanism; In use, pencils are fed one after another at high speed into the inlet through an external feeding device. They enter the inner cavity of the paint collection box through the inlet and come into contact with the paint in the cavity, so that the paint soaks into the surface of the pencil.

[0006] Preferably, the painting mechanism includes: The drive component is fixedly installed on the left side of the outer wall of the paint collection box; The reciprocating component is mounted on the back of the drive component; Specifically, by activating the driving component, the reciprocating component is driven to move horizontally back and forth.

[0007] Preferably, the hedging mechanism includes: A disturbance component is slidably disposed at the bottom of the inner wall of the paint collection box; A flow guiding component is fixedly installed on the inner wall of the paint collection box; When the reciprocating component moves, it will drive the disturbance component to move, disturbing the paint in the paint collection box. Then the paint will flow towards the pencil through the guide component.

[0008] Preferably, the bonding mechanism includes: A blocking component is slidably disposed on the inner wall of the paint collection box; The cleaning component is fixedly installed on the inner wall of the flow guiding component; The paint scraper head refers to the paint removal component. The blocking component floats on top of the paint and scrapes off excess paint from the pencil's surface when it comes into contact with the cleaning component.

[0009] Preferably, the drive assembly includes a fixing plate fixedly connected to the left side of the outer wall of the paint collection box, and a motor is fixedly connected to the front of the fixing plate; The reciprocating assembly includes a rotating plate fixedly connected to the back of the motor output end, and a connecting rod rotatably connected to the back of the rotating plate; The starting motor drives the rotating plate to rotate, which in turn pushes the connecting rod to rotate.

[0010] Preferably, the disturbance component includes eighteen disturbance rings slidably connected to the bottom of the inner wall of the paint collection box, with the eighteen disturbance rings arranged in groups of six, and three connecting frames provided inside the paint collection box; The bottom of each of the three connecting frames is fixedly connected to the top of the three sets of disturbance rings. A connecting frame is slidably connected to the left side of the inner wall of the paint collection box, and the right side of the connecting frame is fixedly connected to the left side of each of the three connecting frames. A sealing ring is fixedly connected to the left side of the inner wall of the paint collection box. The outer wall of the connecting frame is slidably connected to the inner wall of the sealing ring. The side of the connecting frame away from the connecting frame is rotatably connected to the inner wall of the connecting rod. As the connecting rod continues to rotate, it will drive the connecting frame to move laterally back and forth. When the connecting frame moves, it will drive the connecting frame to move, which in turn will drive multiple disturbance rings to move synchronously.

[0011] Preferably, the flow guiding assembly includes three guide tubes fixedly connected to the inner wall of the paint collection box. The inner wall of each of the three guide tubes is provided with several oblique holes, and the outer wall of each of the three guide tubes is slidably connected to the inner wall of the three sets of disturbance rings. Among them, the disturbance ring will slide back and forth synchronously along the outer wall of the guide tube, pushing the paint liquid around the guide tube to flow. Some of the paint liquid will enter the inclined hole and move in the opposite direction of the pencil movement through the inclined hole. The paint and pencil move towards each other, creating a countercurrent flow field. At the same time, the disturbance ring agitates the paint, enhancing its fluidity. As the pencil moves inside the guide tube, its surface is continuously washed by the paint, ensuring more thorough contact between the pencil and the paint. This allows the paint to fully saturate the pencil without reducing the pencil's feeding speed, effectively preventing the problem of insufficient saturation due to short contact time between the paint and the pencil. This results in a more uniform paint saturation and ultimately a coating of uniform thickness.

[0012] Preferably, the blocking component includes a cover plate slidably connected to the inner wall of the paint collection box, and two counterweights are fixedly connected to the top of the cover plate; In this design, by placing a cover plate on top of the paint in the paint collection box and adding a counterweight to increase the weight of the cover plate, the cover plate will compress the paint and create a downward pressure constraint. This stabilizes the flow field of the paint in the collection box and effectively prevents waves or splashes from being generated at the top of the paint when the disturbance ring pushes the paint to flow. This would dissipate some of the kinetic energy of the paint, thus causing the paint to concentrate and flow into the inclined hole. This ensures that the paint entering the inclined hole is sufficient and stable. In addition, the continuous disturbance of the paint by the disturbance ring can also play a stirring role, so that the elastic resin in the paint is evenly dispersed, further improving the adhesion performance of the paint on the pencil surface.

[0013] Preferably, the cleaning component includes two scraper rings fixedly connected to the inner wall of the guide tube, and three rubber rings fixedly connected to the left and right sides of the inner wall of the paint collection box; The central axis of the three rubber rings on the left is aligned with the central axis of the three feed inlets, and the central axis of the three rubber rings on the right is aligned with the central axis of the three discharge outlets. The scraper ring is V-shaped. As the pencil moves, when the pencil reaches the scraper ring, the excess paint on the pencil surface is gradually scraped off by the tapering arc surface on the left side of the scraper ring. As the arc surface of the scraper ring continues to shrink along the direction of the pencil's movement, the scraper ring squeezes out any remaining paint, making it evenly adhere to the pencil surface. Since the scraper ring's tilt direction is opposite to the tilt direction of the oblique hole, and with the disturbance of the disturbance ring, the paint flowing from the oblique hole can quickly re-adhere to the pencil surface. The pencil then moves to the scraper on the right, where excess paint is scraped off again. The paint then re-adheres to the pencil surface. Finally, the pencil contacts the rubber ring on the right, which removes excess paint again, creating a uniform thin coating and completing the pencil painting process. By repeatedly scraping off the paint from the pencil surface and then applying a second coat, the adhesion of the paint to the pencil surface is significantly improved. This effectively prevents the paint from adhering poorly because the skin-feel paint is the last coat of paint on the pencil, and some pencil surfaces already have colored paint on them, which is relatively smooth.

[0014] The present invention has the following beneficial effects: (1) When using this invention, the pencils are pushed into the inner cavity of the paint collection box one by one at high speed through the external feeding equipment. Then the motor is started to drive the rotating plate to rotate. The rotating plate will push the connecting rod to rotate. Through the reciprocating component and the disturbance component, the paint liquid is moved in the opposite direction of the pencil movement through the oblique hole to form a countercurrent flow field. At the same time, the disturbance ring disturbs the paint liquid to enhance its fluidity. The pencil surface will be continuously washed by the paint liquid in the opposite direction, so that the pencil and the paint liquid are in more sufficient contact. Under the premise of not reducing the pencil feeding speed, the paint liquid can fully wet the pencil barrel. This effectively prevents the problem that the skin-feel paint is difficult to fully wet the pencil due to the short contact time between the paint and the pencil. This makes the paint liquid wetted by the pencil more uniform and finally forms a coating with uniform thickness.

[0015] (2) During the movement of the pencil, when the pencil moves to the position of the scraper ring, the excess paint adhering to the pencil surface will be gradually scraped off by the tapered arc surface on the left side of the scraper ring. The scraper ring will squeeze the unremoved paint so that it is evenly adhered to the pencil surface. Since the tilt direction of the scraper ring is opposite to the tilt direction of the oblique hole, it is convenient for the paint flowing from the oblique hole to quickly adhere to the pencil surface again. By repeatedly scraping the paint off the pencil surface by the cleaning component, and then re-dipping and recoating, the adhesion effect of the paint on the pencil surface is significantly improved. It effectively prevents the skin-feel paint from being poorly adhered because the skin-feel paint is the last topcoat on the pencil and some pencil surfaces have already been coated with colored paint, which is relatively smooth.

[0016] (3) By covering the top of the paint liquid in the paint collection box with a cover plate and increasing the weight of the cover plate with a counterweight, the cover plate will squeeze the paint liquid to form a downward pressure constraint, which can stabilize the flow field of the paint liquid in the paint collection box and effectively prevent waves or splashes from being generated at the top of the paint liquid when the disturbance ring pushes the paint liquid to flow, which will dissipate some of the kinetic energy of the paint liquid. This allows the paint liquid to concentrate and flow into the inclined hole, ensuring that the paint liquid entering the inclined hole is sufficient and stable. In addition, the continuous disturbance of the paint liquid by the disturbance ring can also play a stirring role, so that the elastic resin in the paint liquid is evenly dispersed, further improving the adhesion performance of the paint liquid on the pencil surface.

[0017] (4) When the pencil contacts the scraper ring on the left, the present invention can support the end of the pencil near the feed port, ensuring that the pencil can pass straight through the paint collection box. This effectively prevents the pencil from being too long. When the pencil passes through the paint collection box, one end of the pencil contacts the rubber ring on the right and the other end separates from the feed port. If the pencil needs to be moved by the subsequent pencil, the end of the pencil near the feed port will droop slightly, affecting the uniform flushing of the pencil around the oblique hole. At the same time, when the pencil passes straight through the paint collection box, it also ensures that when the pencil contacts the rubber ring on the right, the rubber ring can evenly scrape off the excess paint on the outer surface of the pencil.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: This invention relates to a water-based skin-feel pencil paint application process and dedicated equipment. Please refer to 10. The water-based skin-feel pencil paint application process includes the following steps: Step 1: Using a feeding device, pencils are continuously and rapidly fed into the paint chamber one after another. The pencils will pass through the paint chamber at high speed. Step 2: As the pencil passes through the paint cavity, the paint will come into contact with the pencil and adhere to the pencil surface. Step 3: As the pencil continues to move, it will come into contact with the scraper head, which will scrape off the excess paint from the pencil surface, forming a thin coating and completing the painting process.

[0023] Example 2, please refer to Figures 1-9 This invention relates to a water-based skin-feel pencil paint application process and related equipment. The equipment includes a paint collection box 13, with three inlets 14 on the left side of its inner wall and three outlets 15 on the right side. The central axes of the three inlets 14 and the three outlets 15 are aligned. The paint cavity refers to the paint collection box 13. The equipment also includes: The painting mechanism 1 is fixedly installed on the left side of the outer wall of the paint collection box 13; The counter-pressure mechanism 2 is installed on the inner wall of the paint collection box 13; The bonding mechanism 3 is fixedly installed on the inner wall of the counter-punching mechanism 2; In use, pencils are fed one after another at high speed into the feed inlet 14 through an external feeding device. The pencils enter the inner cavity of the paint collection box 13 through the feed inlet 14 and come into contact with the paint in the cavity, so that the paint soaks into the surface of the pencils.

[0024] The painting mechanism 1 includes: Drive component 11 is fixedly installed on the left side of the outer wall of the paint collection box 13; Reciprocating component 12 is mounted on the back of drive component 11; Specifically, by activating the drive component 11, the reciprocating component 12 is driven to move laterally back and forth.

[0025] Hedging institution 2 includes: Disturbance component 21 is slidably disposed at the bottom of the inner wall of the paint collection box 13; The flow guiding component 22 is fixedly installed on the inner wall of the paint collection box 13; When the reciprocating component 12 moves, it will drive the disturbance component 21 to move, disturbing the paint in the paint collection box 13. Then the paint will flow towards the pencil through the guide component 22.

[0026] The bonding mechanism 3 includes: The blocking component 31 is slidably disposed on the inner wall of the paint collection box 13; Cleaning component 32 is fixedly installed on the inner wall of the flow guiding component 22; The paint scraper head refers to the paint removal component 32; The blocking component 31 floats on top of the paint and scrapes off excess paint from the pencil surface when it comes into contact with the cleaning component 32.

[0027] The drive assembly 11 includes a fixing plate 111 fixedly connected to the left side of the outer wall of the paint collection box 13, and a motor 112 is fixedly connected to the front of the fixing plate 111. The reciprocating assembly 12 includes a rotating plate 121 fixedly connected to the back of the output end of the motor 112, and a connecting rod 122 is rotatably connected to the back of the rotating plate 121. The starting motor 112 drives the rotating plate 121 to rotate, and the rotating plate 121 pushes the connecting rod 122 to rotate.

[0028] The disturbance component 21 includes eighteen disturbance rings 211 that are slidably connected to the bottom of the inner wall of the paint collection box 13. The eighteen disturbance rings 211 are grouped in groups of six. The paint collection box 13 has three connecting frames 212 inside. The bottom of each of the three connecting frames 212 is fixedly connected to the top of the three sets of disturbance rings 211. A connecting frame 213 is slidably connected to the left side of the inner wall of the paint collection box 13, and the right side of the connecting frame 213 is fixedly connected to the left side of the three connecting frames 212. A sealing ring is fixedly connected to the left side of the inner wall of the paint collection box 13. The outer wall of the connecting frame 213 is slidably connected to the inner wall of the sealing ring. The side of the connecting frame 213 away from the connecting frame 212 is rotatably connected to the inner wall of the connecting rod 122. As the connecting rod 122 continues to rotate, it will drive the connecting frame 213 to move laterally back and forth. When the connecting frame 213 moves, it will drive the connecting frame 212 to move, which in turn will drive multiple disturbance rings 211 to move synchronously.

[0029] The flow guiding assembly 22 includes three guide tubes 221 fixedly connected to the inner wall of the paint collection box 13. The inner wall of each of the three guide tubes 221 is provided with several oblique holes 222, and the outer wall of each of the three guide tubes 221 is slidably connected to the inner wall of the three sets of disturbance rings 211. Among them, the disturbance ring 211 will slide back and forth synchronously along the outer wall of the guide tube 221, pushing the paint liquid around the guide tube 221 to flow. Some of the paint liquid will enter the inclined hole 222 and move in the opposite direction of the pencil movement through the inclined hole 222. The paint and pencil move towards each other, creating a countercurrent flow field. At the same time, the disturbance ring 211 agitates the paint, enhancing its fluidity. As the pencil moves inside the guide tube 221, its surface is continuously flushed by the paint, ensuring more thorough contact between the pencil and the paint. This allows the paint to fully saturate the pencil without reducing the pencil feed speed, effectively preventing the problem of insufficient saturation due to short contact time between the paint and the pencil. This results in a more uniform paint saturation on the pencil, ultimately forming a coating of uniform thickness.

[0030] The blocking assembly 31 includes a cover plate 311 that is slidably connected to the inner wall of the paint collection box 13, and two counterweights 312 are fixedly connected to the top of the cover plate 311. In this system, by covering the top of the paint liquid in the paint collection box 13 with a cover plate 311 and increasing the weight of the cover plate 311 with a counterweight block 312, the cover plate 311 will squeeze the paint liquid to form a downward pressure constraint, which can stabilize the flow field of the paint liquid in the paint collection box 13. This effectively prevents waves or splashes from being generated at the top of the paint liquid when the disturbance ring 211 pushes the paint liquid to flow, which would dissipate some of the kinetic energy of the paint liquid. As a result, the paint liquid is concentrated and flows into the inclined hole 222, ensuring that the paint liquid entering the inclined hole 222 is sufficient and stable. In addition, the continuous disturbance of the paint liquid by the disturbance ring 211 can also play a stirring role, so that the elastic resin in the paint liquid is evenly dispersed, further improving the adhesion performance of the paint liquid on the pencil surface.

[0031] The cleaning component 32 includes two scraper rings 321 fixedly connected to the inner wall of the guide tube 221, and three rubber rings 322 fixedly connected to the left and right sides of the inner wall of the paint collection box 13. The central axis of the three rubber rings 322 on the left is aligned with the central axis of the three feed ports 14, and the central axis of the three rubber rings 322 on the right is aligned with the central axis of the three discharge ports 15. The scraper ring 321 is V-shaped. During pencil movement, when the pencil reaches the position of the scraper ring 321, it passes through the tapered arc surface on the left side of the scraper ring 321, as... Figure 8 As shown in position G, excess paint adhering to the pencil surface is gradually scraped away. As the arc surface of the scraper ring 321 continues to shrink along the pencil's travel direction, the scraper ring 321 squeezes out any remaining paint, causing it to adhere evenly to the pencil surface. Because the tilt direction of the scraper ring 321 is opposite to the tilt direction of the oblique hole 222, combined with the disturbance of the disturbance ring 211, the paint flowing from the oblique hole 222 is facilitated to quickly re-adhere to the pencil surface, as shown in position G. Figure 6 As shown; The pencil then moves to the scraper ring 321 on the right, where excess paint is scraped off again. The paint then adheres to the pencil surface again. Finally, the pencil comes into contact with the rubber ring 322 on the right, which removes excess paint from the pencil surface again, forming a uniform thin coating and completing the pencil painting process. By scraping off the paint from the pencil surface multiple times and then applying a second coat, the adhesion of the paint to the pencil surface is significantly improved. This effectively prevents the paint from adhering poorly because the skin-feel paint is the last coat of paint on the pencil, and some pencil surfaces already have colored paint on them, which is relatively smooth.

[0032] A specific application of this embodiment is as follows: When using this invention, pencils are pushed one after another into the feed inlet 14 at high speed through an external feeding device. They enter the inner cavity of the paint collection box 13 through the feed inlet 14 and come into contact with the paint liquid in the cavity. Then, the motor 112 is started to drive the rotating plate 121 to rotate. The rotating plate 121 will push the connecting rod 122 to rotate. The connecting rod 122 will pull the connecting frame 213 to move towards the motor 112. As the rotation angle of the connecting rod 122 continues to change, it will push the connecting frame 213 to move away from the motor 112. As the connecting rod 122 continues to rotate, it will drive the connecting frame 213 to move laterally back and forth. When the connecting frame 213 moves, it will drive the connecting frame 212 to move, which in turn will drive multiple disturbance rings 211 to slide back and forth synchronously along the outer wall of the guide tube 221, pushing the paint around the guide tube 221 to flow. Some of the paint will enter the inclined hole 222 and move in the opposite direction of the pencil movement through the inclined hole 222. The paint and pencil move towards each other, forming a countercurrent flow field. At the same time, the disturbance ring 211 disturbs the paint and enhances its fluidity. As the pencil moves inside the guide tube 221, its surface is continuously washed by the paint in the opposite direction, making the pencil and paint more fully in contact. This allows the paint to fully wet the pencil without reducing the pencil feeding speed, effectively preventing the problem of insufficient paint wetting of the pencil due to short contact time between the skin-feel paint and the pencil. This makes the paint wetting of the pencil more uniform, ultimately forming a coating of uniform thickness. Secondly, during the pencil's movement, when the pencil reaches the position of the scraper ring 321, it passes through the tapered arc surface on the left side of the scraper ring 321, such as... Figure 8 As shown in position G, excess paint adhering to the pencil surface is gradually scraped away. As the arc surface of the scraper ring 321 continues to shrink along the pencil's travel direction, the scraper ring 321 squeezes out any remaining paint, causing it to adhere evenly to the pencil surface. Because the tilt direction of the scraper ring 321 is opposite to the tilt direction of the oblique hole 222, combined with the disturbance of the disturbance ring 211, the paint flowing from the oblique hole 222 is facilitated to quickly re-adhere to the pencil surface, as shown in position G. Figure 6 As shown; The pencil then moves to the scraper ring 321 on the right, where excess paint is scraped off again. The paint then adheres to the pencil surface again. Finally, the pencil comes into contact with the rubber ring 322 on the right, which removes excess paint from the pencil surface again, forming a uniform thin coating and completing the pencil painting process. By scraping off the paint from the pencil surface multiple times and then applying a second coat, the adhesion of the paint to the pencil surface is significantly improved. This effectively prevents the paint from adhering poorly because the skin-feel paint is the last coat of paint on the pencil and some pencil surfaces already have colored paint on them, which is relatively smooth. Secondly, by covering the top of the paint liquid in the paint collection box 13 with a cover plate 311 and increasing the weight of the cover plate 311 with a counterweight block 312, the cover plate 311 will squeeze the paint liquid to form a downward pressure constraint, which can stabilize the flow field of the paint liquid in the paint collection box 13. This effectively prevents waves or splashes from being generated at the top of the paint liquid when the disturbance ring 211 pushes the paint liquid to flow, which will dissipate some of the kinetic energy of the paint liquid. As a result, the paint liquid is concentrated and flows into the inclined hole 222, ensuring that the paint liquid entering the inclined hole 222 is sufficient and stable. In addition, the continuous disturbance of the paint liquid by the disturbance ring 211 can also play a stirring role, so that the elastic resin in the paint liquid is evenly dispersed, further improving the adhesion performance of the paint liquid on the pencil surface. Secondly, when the pencil contacts the scraper ring 321 on the left, the end of the pencil near the feed inlet 14 can be supported to ensure that the pencil can pass straight through the paint collection box 13. This effectively prevents the pencil from being too long. When it passes through the paint collection box 13, if one end of the pencil contacts the rubber ring 322 on the right and the other end separates from the feed inlet 14, the pencil needs to be moved by a subsequent pencil. If the pencil is pushed to move, the end of the pencil near the feed inlet 14 will droop slightly, affecting the uniform rinsing of the pencil by the oblique hole 222. At the same time, when the pencil passes straight through the paint collection box 13, it also ensures that when the pencil contacts the rubber ring 322 on the right, the rubber ring 322 can evenly scrape off the excess paint on the outer surface of the pencil.
