Description

Technical Field

[0001] The present invention relates to the field of biodegradable technology, and in particular to a biodegradable and environment-friendly label production device. Background Art

[0002] Biodegradable materials are key to producing environmentally friendly label sheets. Common materials include corn starch, wood fibers (such as pulp), soda paper, and bio-based plastics. These materials are not only degradable in the natural environment, but also generally have a lower carbon footprint. The biodegradable materials are mixed with possible enhancers (such as dyes or additives) for subsequent molding and processing. The raw materials are molded into labels of the desired shape and size by extruders or injection molding machines. These equipment require precise control of temperature and pressure to ensure product quality and consistency. The labels are printed and protected using environmentally friendly inks and coating technologies to enhance their durability and visual appeal. The labels are cut to the desired size by automatic cutting equipment and packaged to ensure the protection of the product during transportation and use. There are still the following defects in specific use: 1. If the ink is not completely dry, the pattern or text on the printed surface may be blurred. This will cause the image to be distorted or unclear, affecting the visual effect and printing quality. At the same time, the liquid or semi-solid ink may be transferred or spread during the handling or transportation of the printed matter. This may lead to poor printing quality, such as undesirable imprints or color transfer on the printed matter.

[0003] 2. Lines or marks may make the surface of the printed product uneven or have obvious flaws, thus affecting the overall visual effect. These lines or marks may cause the pattern or text of the printed product to deform or distort, thus affecting the quality and clarity of the printing. At the same time, if the lines or marks are not caused by the design intention, they may cause inconsistency between prints, which is particularly important in mass printing.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention utilizes the first piston rod and the second piston cylinder to cooperate with each other, and the multi-angle synchronous drying mechanism can dry the printed matter from multiple angles. Compared with the traditional single-angle or fixed-position drying method, this mechanism can cover the printed matter surface more comprehensively, reduce the drying dead angle, and thus improve the drying efficiency. Furthermore, through the reciprocating motion of the piston, the flow of hot air or drying medium can be accelerated, so that the solvent on the surface of the printed matter can evaporate quickly, shortening the drying time. The multi-angle synchronous drying mechanism helps to reduce the quality problems of printed matter caused by uneven drying, such as color difference, spots, wrinkles, etc. In addition, since the drying process is more uniform and rapid, the surface damage of the printed matter caused by long-term exposure to high temperature environment can be avoided. Furthermore, by improving the drying efficiency, the printing cycle can be shortened and the production efficiency can be improved. At the same time, the multi-angle synchronous drying mechanism is also easy to integrate and optimize with other parts of the printing machine, further improving the overall performance. Finally, the efficient multi-angle synchronous drying mechanism can usually complete the drying process in a short time, which means that the energy consumption is relatively low. Compared with the traditional drying method, the energy-saving effect is significant, which helps to reduce production costs and environmental impact; (2) The present invention utilizes the coupling plate and the rake rod to cooperate with each other, and the flattening and grinding mechanism can flatten the printed surface by mechanical or pressure means after printing is completed, which helps to eliminate the unevenness or texture that may be formed during the printing process, making the surface of the printed product more uniform and smooth. At the same time, the flattening and grinding mechanism can reduce or eliminate the defects on the surface of the printed product, such as uneven ink layer, lines or marks left during the printing process, etc., which is crucial to ensure the visual effect and texture of the printed product. In addition, in some cases, especially when using a thicker ink layer or printing special effects on the surface, the flattening and grinding mechanism can help the ink color to be more evenly distributed on the surface of the printed material, reducing the problem of spots or uneven ink color. In addition, the flattening and grinding mechanism can directly perform surface treatment during the printing process, reducing the need for subsequent manual treatment, thereby improving production efficiency and reducing production costs. Finally, the flattening and grinding mechanism can reduce burrs, particles and defects on the surface of the printed product, so that the ink or coating is more evenly attached to the surface of the printed product, improving the printing effect and color expression, and making the surface of the printed product more flat and smooth, reducing the possibility of surface wear and damage; (3) The present invention utilizes the push-sweeper block and the trapezoidal box to cooperate with each other, and the drainage direction mechanism can effectively reduce or avoid defects such as floating ink, blur, and stains on the printed matter, ensuring the clarity and neatness of the printed matter. At the same time, by accurately controlling the distribution and residual amount of ink, the drainage direction mechanism helps to maintain the consistency and uniformity of the color on the printed matter, thereby improving the overall visual effect. Furthermore, in the traditional printing process, the excess ink on the printed matter often needs to be manually cleaned after stopping the machine, which not only wastes time but also affects production efficiency. The drainage direction mechanism can automatically process these inks, reduce downtime, and improve production efficiency. In addition, since the printing defects caused by ink residue are reduced, the scrap rate is also reduced, further improving production efficiency and economic benefits. Furthermore, the drainage direction mechanism can effectively guide the excess ink into the centralized processing area to avoid them leaving unnecessary marks on the printed matter. Finally, controlling the direction of the ink not only helps to reduce the waste of ink, but also reduces the cost of materials used in the printing process, which is also more environmentally friendly.

[0020] The following are the complete usage steps and working principles of the above embodiment: The device is mainly used for: Figure 1 As shown, first, the operator needs to install the printing plate 16 on the printing machine 1. The printing plate 16 has graphic information, which can be produced by different methods, such as digital printing or traditional relief printing. Then, ink is applied to the surface of the printing plate 16 to ensure that the ink evenly covers the required area of ​​the printing plate 16. Secondly, after the printing plate 16 has been inked, the graphic part of the printing plate 16 is in contact with the environmentally friendly surface sheet of the printing material, and the initial position of the environmentally friendly surface sheet of the printing material is to be placed inside the workbench 13. Then, the printing machine 1 is started through the control panel 11, and then the moving cylinder 15 of the printing machine 1 is driven to move on the guide groove 14 and apply pressure to transfer the ink to the printing material to form a pattern or text. When a round of printing is completed, the operator needs to unload the old printing plate 16 from the printing machine 1 so as to install the next printing plate 16 to be used. The multi-angle synchronous drying mechanism 2 is used to quickly dry the ink coating on the surface of the printed material after printing. When the mechanism is used specifically: like Figures 3 to 6 As shown, when the movable cylinder 15 moves inside the guide groove 14 to drive the printing plate 16 to print the environmentally friendly surface sheet of the printing material, since the lower end of the guide groove 14 is fixedly connected to the rack plate 21, and the rack plate 21 and the ring gear 22 are meshed with each other to form a meshing transmission, the movement of the movable cylinder 15 will cause the ring gear 22 to rotate, and then the first eccentric wheel 23 fixedly connected to the upper end of the ring gear 22 will rotate, and the first piston rod 24 is fixedly connected to the eccentric part of the end of the first eccentric wheel 23 away from the rack plate 21, and The first piston rod 24 is slidably connected to the inside of the piston cylinder 210, so that when the first eccentric wheel 23 rotates, it will push the first piston rod 24 to move horizontally back and forth inside the piston cylinder 210. In addition, the first piston rod 24 is eccentrically fixedly connected to the second eccentric wheel 25 at one end away from the first eccentric wheel 23, and the second eccentric wheel 25 is eccentrically fixedly connected to the adapter rod 27 at one end away from the first piston rod 24. Therefore, the horizontal reciprocating movement of the first piston rod 24 will also drive the cam 26 to rotate and make the cam 26 pull the adapter rod 27 to move horizontally back and forth. Furthermore, the end of the transfer rod 27 away from the cam 26 is rotatably connected to the snap plate 28, and the side of the snap plate 28 away from the transfer rod 27 is fixedly connected to the second piston rod 29, and the second piston rod 29 is also slidably connected to the inside of the piston cylinder 210. Therefore, when the transfer rod 27 moves horizontally back and forth, it will pull the snap plate 28 to move horizontally back and forth, and thus the horizontal reciprocating movement of the snap plate 28 will synchronously pull the second piston rod 29 to move horizontally back and forth inside the piston cylinder 210. In this way, through the first piston rod 24 and the second piston rod 29 The opposite horizontal reciprocating movements are used to inhale air from the air inlet opened on the outer wall of the top of the piston cylinder 210, and then the air is discharged from the air outlet nozzle 211 that is fixedly connected to the outer wall of both sides of the piston cylinder 210. In addition, an infrared radiator is installed inside the air outlet nozzle 211. Therefore, after the air passes through the infrared energy released by the infrared radiator, the air molecules will first vibrate and increase to generate heat, and then the cold air is heated to hot air, so that after the printing plate 16 prints the environmentally friendly surface sheet of the printed material, it is sprayed onto the upper surface of the environmentally friendly surface sheet of the printed material; In addition, a concave wheel 212 is fixedly connected to one end of the ring gear 22 away from the first eccentric wheel 23, so the rotation of the ring gear 22 will also synchronously drive the concave wheel 212 to rotate. In addition, the concave side surfaces arranged on both sides of the concave wheel 212 conflict with the outer wall of the piston column 216, so the rotation of the concave wheel 212 will push the piston column 216 to move horizontally toward each other inside the piston cylinder 214. In addition, the outer wall of the piston column 216 is also rotatably connected to an arc rod 217, and two adjacent piston columns 216 are connected by the arc rod 217. Therefore, when one of the piston rods 216 is pushed to move horizontally back and forth inside the piston cylinder 214, the arc rod 217 will be deflected, so that multiple piston rods 216 can move horizontally back and forth inside the piston cylinder 214 synchronously, so that air will be sucked in from the air inlet hole opened on the outer wall of the piston cylinder 214, and then the air will be discharged through the exhaust nozzle 215. Furthermore, a heat exchanger is installed inside the exhaust nozzle 215, and the cold air will be converted into hot air after entering and discharged, so as to achieve rapid drying of the bottom surface of the environmentally friendly surface sheet of the printed material.

[0021] Summary 1: Compared with the prior art, before the ink dries, the ink or coating on the surface of the printed matter is often still in a liquid or semi-solid state. The present mechanism realizes that the first piston rod 24 and the second piston rod 29 move horizontally back and forth in opposite directions to inhale air from the air inlet opened on the outer wall of the top end of the piston cylinder 210, and then discharges air from the air outlet nozzles 211 that penetrate the outer walls of both sides of the piston cylinder 210 and are fixedly connected. The multiple piston rods 216 synchronously move horizontally back and forth inside the piston cylinder 214, so that air is inhaled from the air inlet opened on the outer wall of the piston cylinder 214, and then the air is discharged through the exhaust nozzles 215. The multi-angle synchronous drying mechanism 2 can dry the printed matter from multiple angles. The multi-angle synchronous drying mechanism 2 can dry the printed product. Compared with the traditional single-angle or fixed-position drying method, this mechanism can cover the surface of the printed product more comprehensively, reduce the drying dead corners, and thus improve the drying efficiency. Furthermore, the reciprocating motion of the piston can accelerate the flow of hot air or drying medium, so that the solvent on the surface of the printed product can evaporate quickly, shortening the drying time. The multi-angle synchronous drying mechanism 2 helps to reduce the quality problems of printed products caused by uneven drying, such as color difference, spots, wrinkles, etc. In addition, since the drying process is more uniform and rapid, it can avoid damage to the surface of the printed product caused by long-term exposure to high temperature environment. Furthermore, by improving the drying efficiency, the printing cycle can be shortened and production efficiency can be improved. At the same time, the multi-angle synchronous drying mechanism 2 is also easy to integrate and optimize with other parts of the printing machine 1 to further improve the overall performance. Finally, the efficient multi-angle synchronous drying mechanism 2 can usually complete the drying process in a short time, which means that the energy consumption is relatively low. Compared with the traditional drying method, the energy-saving effect is significant, which helps to reduce production costs and environmental impact; The flattening and grinding mechanism 3 is used to make the printed surface smoother by applying appropriate pressure and friction. When the mechanism is used specifically: like Figures 7 and 8 As shown, a gear ring 31 is rotatably connected to the lower end of the moving cylinder 15, and the gear ring 31 is meshed with the rack plate 21. Therefore, the movement of the moving cylinder 15 inside the guide groove 14 will also drive the gear ring 31 to rotate, and then the turntable 34 rotatably connected to the outer wall of one end of the clamping plate 32 will rotate synchronously. Furthermore, an obstacle column 35 is fixedly connected to the outer wall of the turntable 34, one of the obstacle columns 35 abuts against the outer wall of one end of the convex rod block 39, and then when the turntable 34 rotates clockwise, one of the obstacle columns 35 will push the convex rod block 39 to move to the right side. Therefore, the convex rod block 39 fixedly connected to the outer wall of the lower end of the clamping plate 32 will drive the clamping plate 32 to move to the right side together. Furthermore, the The telescopic block 310 is fixedly connected to one end, and the push plate 311 is fixedly connected to the upper end of the telescopic block 310. Therefore, the rightward movement of the clamping plate 32 will synchronously drive the telescopic block 310 and the push plate 311 to move, and then the movement of the push plate 311 pulls the nail rake rod 312 to move horizontally synchronously. In addition, when the turntable 34 rotates until another obstacle column 35 fixedly connected to the surface of the turntable 34 touches one end of the double-headed swing rod 33, the double-headed swing rod 33 will deflect counterclockwise, and then the connecting column 38 clamped at one end of the double-headed swing rod 33 will pull the clamping plate 32 to move to the left for reset. In summary, the horizontal reciprocating movement of the clamping plate 32 is used to realize the nail rake rod 312 to scrape the printed matter after printing inside the workbench 13; Summary 2: Compared with the existing technology that realizes the lines or marks left in the printing process, the present mechanism realizes that the convex rod block 39 on the outer wall of the lower end of the clamping plate 32 will drive the clamping plate 32 to move to the right together, and the double-headed swing rod 33 will deflect counterclockwise, and then the connecting column 38 clamped at one end of the double-headed swing rod 33 will pull the clamping plate 32 to move to the left for reset. The flattening and grinding mechanism 3 can flatten the printed surface by mechanical or pressure methods after printing is completed, which helps to eliminate the unevenness or texture that may be formed in the printing process, making the surface of the printed product more uniform and smooth. At the same time, the flattening and grinding mechanism 3 can reduce or eliminate the defects on the surface of the printed product, such as uneven ink layer, lines or marks left in the printing process, etc. , which is very important to ensure the visual effect and texture of the printed matter. Moreover, in some cases, especially when using a thicker ink layer or printing special effects on the surface, the flattening and grinding mechanism 3 can help the ink color to be more evenly distributed on the surface of the printed material, reducing the problem of spots or uneven ink color, and through the flattening and grinding mechanism 3, the surface treatment can be directly performed during the printing process, reducing the need for subsequent manual treatment, thereby improving production efficiency and reducing production costs. Finally, through the flattening and grinding mechanism 3, the burrs, particles and defects on the surface of the printed matter can be reduced, so that the ink or coating can be more evenly attached to the surface of the printed matter, improving the printing effect and color expression, and making the surface of the printed matter flatter and smoother, reducing the possibility of surface wear and damage; The drainage direction mechanism 4 is used to adjust and control the flow direction of ink during the printing process. When the mechanism is used specifically: like Figures 9 and 10 As shown, when the movable cylinder 15 moves inside the guide rail groove 14 until the trigger rod 414 fixedly connected to the outer wall of the movable cylinder 15 contacts the touch switch 413, the touch switch 413 triggers the electric telescopic rod 41 to extend, and then the extension of the electric telescopic rod 41 will push the first long connecting rod 42 to deflect to the side away from the electric telescopic rod 41, and further, one side outer wall of the first long connecting rod 42 is also rotatably connected to the connecting rod 43, so after the first long connecting rod 42 deflects to the side away from the electric telescopic rod 41, it will drive the connecting rod 43 to deflect upward, and further, the end of the connecting rod 43 away from the connecting rod 43 is also rotatably connected to the second long connecting rod 49, so the upward deflection of the connecting rod 43 will pull the second long connecting rod 49 to deflect to the side away from the electric telescopic rod 41, in addition, the second long connecting rod 49 and the first long connecting rod 42 are respectively slidably connected to the second clamping block 410 and the first clamping block 44, and the second clamping block 410 and the first The outer wall of one side of a clamping block 44 is respectively fixedly connected with the second fixing rod 411 and the first fixing rod 45. Therefore, when the second long connecting rod 49 and the first long connecting rod 42 are deflected to the side away from the electric telescopic rod 41, they also slide downward inside the second clamping block 410 and the first clamping block 44 respectively. In addition, the deflection of the second long connecting rod 49 and the first long connecting rod 42 to the side away from the electric telescopic rod 41 will pull the second fixing rod 411 and the first fixing rod 45 to deflect to the side of the electric telescopic rod 41. As a result, the wedge plate 46 connected to the outer wall of one side of the second fixing rod 411 and the first fixing rod 45 will be rotated. With the deflection of the second fixing rod 411 and the first fixing rod 45, the push-sweep block 47 fixedly connected to the outer wall of one side of the wedge plate 46 will slide in the cavity opened inside the trapezoidal slide plate 48, and then the push-sweep block 47 will guide the ink remaining on the printed matter into the arc-shaped cavity opened in the trapezoidal box body 412. Summary 3: Compared with the prior art, some undried ink or ink may remain on the printed matter. If not handled in time, these inks may be transferred to each other during the stacking or processing of the printed matter. The present mechanism realizes that the wedge plate 46 rotatably connected to the outer wall of one side of the second fixed rod 411 and the first fixed rod 45 will make the push-sweep block 47 fixedly connected to the outer wall of one side of the wedge plate 46 slide in the cavity opened inside the trapezoidal slide plate 48 as the second fixed rod 411 and the first fixed rod 45 deflect. Then, the push-sweep block 47 will guide the ink remaining on the printed matter into the arc-shaped cavity opened in the trapezoidal box 412. The drainage direction mechanism 4 can effectively reduce or avoid the floating ink, blur, stains and other defects on the printed matter, ensure the clarity and neatness of the printed matter, and at the same time, by accurately controlling the distribution and residual amount of ink, the drainage direction mechanism 4 helps to maintain The consistency and uniformity of the colors on the printed products improve the overall visual effect. In addition, in the traditional printing process, the excess ink on the printed products often needs to be manually cleaned after stopping the machine, which not only wastes time but also affects production efficiency. The drainage direction mechanism 4 can automatically process these inks, reduce downtime, and improve production efficiency. In addition, since the printing defects caused by ink residue are reduced, the scrap rate is also reduced, further improving production efficiency and economic benefits. In addition, the drainage direction mechanism 4 can effectively guide the excess ink into the centralized processing area to avoid leaving unnecessary marks on the printed products. Finally, controlling the direction of the ink not only helps to reduce the waste of ink, but also reduces the cost of materials used in the printing process, and is more environmentally friendly. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
