Description

Technical Field

[0001] The utility model relates to the technical field of drying machines, in particular to a drying machine used for plastic packaging printing. Background Art

[0002] Plastic packaging printing is a key component of the modern packaging industry. By printing exquisite patterns, text, and other information onto plastic packaging materials, it imparts an attractive appearance and conveys important product information. Dryers play a crucial role in the plastic packaging printing process, rapidly removing ink solvents from the printed plastic surface, allowing the ink to dry and solidify quickly, ensuring print quality and enhancing the packaging's wear resistance and aesthetics. Dryers are essential for the production of plastic packaging for a wide range of products, including food and daily necessities.

[0003] Traditional plastic packaging printing dryers primarily consist of a drying chamber, heating components, ventilation equipment, and a conveyor system. The drying chamber, a space where printed materials are dried, is typically a sealed enclosure to prevent heat loss and solvent evaporation. The heating components generate heat, typically through heating wires, steam pipes, or infrared lamps, to evaporate the solvent in the ink. The ventilation system primarily consists of a fan and ventilation ducts. The fan circulates air within the drying chamber, expelling air laden with solvent vapor and introducing fresh air. The conveyor system transports the printed materials through the drying chamber at a controlled speed, ensuring sufficient time for the printed materials to complete the drying process.

[0004] Traditional conveying devices simply transport printed materials at a fixed speed, without integrating with the drying conditions and the connection to subsequent processes. The control system is simple, and it is difficult to accurately monitor the real-time status in the drying room (such as whether the solvent has completely evaporated and whether the printed materials have reached the drying standard). This inability to automatically stop the material will bring many adverse effects. In terms of product quality, since the feeding cannot be stopped automatically, printed materials that are not completely dried will be conveyed out, resulting in inconsistent drying levels of the printed materials, which in turn affects the adhesion of the ink and the appearance quality of the packaging, such as ink fading, blurred patterns and other problems. In terms of production efficiency, undried printed materials will stick together and need to be manually sorted and re-dried, which not only increases labor costs, but also slows down the entire production process, reduces production efficiency, increases production costs, and is also not conducive to mass production and quality stability of products. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a drying machine for plastic packaging printing, which aims to improve the problem that traditional devices cannot automatically stop feeding, resulting in incompletely dried printed products being conveyed out, making the drying degree of the printed products inconsistent.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a drying machine for plastic packaging printing, comprising a transmission platform, a material blocking component is provided on the side wall of the transmission platform, and a drying component is provided on the side wall of the transmission platform;

[0007] The material blocking assembly includes a connecting box, which is fixedly connected to the side wall of the transmission platform, a pushing rod is fixedly connected to the bottom of the connecting box, and a gear column is fixedly connected to the output end of the pushing rod, and a transmission gear is rotatably connected to the bottom of the connecting box, and the transmission gear is meshed with the gear column. The transmission gear is fixedly connected to a transmission shaft inside, and the transmission shaft is rotatably connected to the inside of the connecting box, and the outer wall of the transmission shaft is fixedly connected to gear 1, and the inside of the connecting box is rotatably connected to gear 2, and the gear 2 is meshed with the gear 1. The tops of gear 2 and gear 1 are both fixedly connected to a connecting platform, and the side wall of the connecting platform is fixedly connected to a material blocking plate.

[0008] Furthermore, the drying assembly includes a drying box, and the drying box is fixedly connected to the side wall of the transmission platform.

[0009] Furthermore, a plurality of electric heating plates are provided on the outer wall of the transmission platform, and a plurality of inner platforms are fixedly connected to the interior of the transmission platform.

[0010] Furthermore, a sliding column is fixedly connected to the interior of the drying box, and an operating shaft is fixedly connected to the side wall of the sliding column.

[0011] Furthermore, a fixed shaft is fixedly connected to the side wall of the operating shaft, and a clamping plate is fixedly connected to one end of the fixed shaft.

[0012] Furthermore, a plurality of connecting shafts are fixedly connected to the interior of the inner platform, and a clamping block is slidably connected to the outer wall of each connecting shaft.

[0013] Furthermore, a side wall of the clamping block is provided with a bevel edge, and an outer wall of the connecting shaft is sleeved with a spring.

[0014] Furthermore, a slip ring is slidably connected to the outer wall of the fixed shaft, and the slip ring is slidably connected to the inside of the inner platform.

[0015] The utility model has the following beneficial effects:

[0016] In this utility model, the push rod first pushes the tooth column, which then moves horizontally. Finally, the rotation of gears 1 and 2 drives the connecting platform on top, which in turn changes the angle of the material blocking plate on the connecting platform's sidewall. This automatically stops and pushes the printed matter on the transfer platform, ensuring that each printed matter is dried to the ideal state. This helps keep the ink firmly attached to the plastic packaging, making the patterns and text clear and colorful.

[0017] 2. In the utility model, when the operating shaft is subjected to force, the sliding column on its side wall will be displaced, and finally the card block will be pushed to drive the card plate to release the engagement state from the inside of the inner platform, and the card block is pushed by the spring so that the card block can be reset and the engagement state can be kept stable. When it is necessary to dry a plastic packaging with higher temperature requirements and a larger printing area, the original heating plate can be easily removed and replaced with a heating plate with higher power and more suitable size to meet new production requirements and improve the adaptability of the equipment to different production tasks.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 2 , the utility model provides an embodiment: a drying machine for plastic packaging printing, comprising a transmission platform 1, a material blocking component is provided on the side wall of the transmission platform 1, and a drying component is provided on the side wall of the transmission platform 1;

[0025] The material blocking assembly includes a connecting box 2, which is fixedly connected to the side wall of the transmission platform 1. A pushing rod 3 is fixedly connected to the bottom of the connecting box 2, and a tooth column 4 is fixedly connected to the output end of the pushing rod 3. A transmission gear 5 is rotatably connected to the bottom of the connecting box 2, and the transmission gear 5 is meshed with the tooth column 4. A transmission shaft 6 is fixedly connected to the inside of the transmission gear 5, and the transmission shaft 6 is rotatably connected to the inside of the connecting box 2. A gear 1 7 is fixedly connected to the outer wall of the transmission shaft 6, and a gear 2 8 is rotatably connected to the inside of the connecting box 2, and the gear 2 8 is meshed with the gear 1 7. The tops of the gears 2 8 and 1 7 are fixedly connected to a connecting platform 9, and a material blocking plate 10 is fixedly connected to the side wall of the connecting platform 9.

[0026] Specifically, when faced with the task of transporting printed materials on the surface of the transmission table 1, the push rod 3 is first started. Once the push rod 3 is started, it first applies a driving force to the gear column 4, causing the gear column 4 to move horizontally. Since there is a meshing relationship between the gear column 4 and the transmission gear 5, the horizontal displacement of the gear column 4 will drive the transmission gear 5 to start rotating. At this time, the transmission shaft 6 inside the transmission gear 5 will also rotate synchronously with the transmission gear 5. During the rotation of the transmission shaft 6, the gear 1 7 on its top will rotate accordingly inside the connecting box 2. As the gear 1 7 rotates, it will also drive the gear 2 8 to rotate inside the connecting box 2 by virtue of its meshing relationship with the gear 2 8. Through this meshing relationship between the gear 1 7 and the gear 2 8 The coordinated rotation can drive the connecting platform 9 on top of them to rotate, and the rotation of the connecting platform 9 will immediately cause the angle of the material blocking plate 10 on its side wall to change, and the change in the angle of the material blocking plate 10 plays an extremely critical role. It can automatically stop and push the printed matter on the surface of the transmission platform 1. Through this precise automatic material stopping and pushing control, it can effectively ensure that the drying degree of each printed matter can reach the ideal state. This has an important impact on the quality of the printed matter, because only when the printed matter is appropriately dry can it help to keep the ink firmly attached to the plastic packaging, so that the patterns and text on the printed matter can be clearly presented, and the colors can also remain bright and beautiful, ensuring that the appearance quality of the printed matter meets the requirements.

[0027] Reference Figure 3The drying component includes a drying box 11, which is fixedly connected to the side wall of the transmission platform 1. A plurality of electric heating plates 12 are provided on the outer wall of the transmission platform 1. A plurality of inner platforms 17 are fixedly connected to the inside of the transmission platform 1. A sliding column 13 is fixedly connected to the inside of the drying box 11. The side wall of the sliding column 13 is fixedly connected to the operating shaft 14. The side wall of the operating shaft 14 is fixedly connected to the fixed shaft 15. One end of the fixed shaft 15 is fixedly connected to the clamping plate 16. A plurality of connecting shafts 18 are fixedly connected to the inside of the inner platform 17. The outer wall of each connecting shaft 18 is slidably connected to a clamping block 19. The side wall of the clamping block 19 is provided with a bevel edge 21. The outer wall of the connecting shaft 18 is sleeved with a spring 20. The outer wall of the fixed shaft 15 is slidably connected to a slip ring 22, and the slip ring 22 is slidably connected to the inside of the inner platform 17.

[0028] Specifically, before the printed matter enters the drying box 11 for drying, it will first pass through the electric heating plate 12 for preliminary drying of the surface. The electric heating plate 12 is a key component in the entire printing production process. The good or bad running state of the electric heating plate 12 is directly related to the preliminary drying effect of the printed matter. When the electric heating plate 12 needs to be maintained or replaced due to long-term use or other factors, it is necessary to follow specific steps. First, pull the operating shaft 14. After being subjected to external force, the operating shaft 14 will drive the sliding column 13 closely connected to its side wall to displace. Then, the fixed shaft 15 on the side wall of the sliding column 13 will displace synchronously with the displacement of the sliding column 13. In this process, the slip ring 22 on the outer wall of the fixed shaft 15 will enter the inner platform 17 under its drive. Subsequently, the surface of the slip ring 22 will apply a thrust to the block 19 with the help of the special geometric structure relationship generated by the inclined edge 21 set on the side wall of the block 19. , so that the slip ring 22 can smoothly enter the inner side of the block 19, and then, the operating shaft 14 is pulled outward again. At this time, the slip ring 22 will slide on the outer wall of the fixed shaft 15 until it is tightly fitted with the card plate 16. During this fitting process, the slip ring 22 will push the block 19 again, thereby driving the card plate 16 to release the engagement state from the inside of the inner platform 17. At the same time, with the help of the elastic force of the spring 20, the block 19 can be pushed to return to its initial position, and ensure that the block 19 can stably maintain the engagement state during the subsequent working process. This ingenious mechanical structure design is of great significance. When production needs change, such as the need to dry a plastic packaging with higher temperature requirements and a larger printing area, the convenience of this structure can be fully utilized to easily remove the original heating plate and then replace it with a heating plate with higher power and more suitable size to meet the new production requirements, greatly improving the adaptability of the equipment to different production tasks.

[0029] Working principle: When it is necessary to transport the printed matter on the surface of the transmission table 1, the push rod 3 is started. The push rod 3 first outputs a driving force to the gear column 4 to drive the gear column 4 to move horizontally, and drives the transmission shaft 6 to rotate through the meshing relationship with the transmission gear 5. At this time, the transmission shaft 6 inside the transmission gear 5 follows the synchronous rotation. During the rotation process, the transmission shaft 6 will drive the gear 1 7 on its top to rotate inside the connecting box 2, and further drive the gear 2 8 to rotate inside the connecting box 2 through the meshing relationship between the gear 1 7 and the gear 2 8. The rotation of the gear 1 7 and the gear 2 8 can drive the top connecting platform 9 to rotate, and then drive the angle of the side wall blocking plate 10 of the connecting platform 9 to change, and automatically stop and push the printed matter on the surface of the transmission table 1, thereby ensuring that the drying degree of each printed matter can reach the ideal state. This helps to keep the ink firmly attached to the plastic packaging, making the patterns and text clear and colorful. The printed matter will be preliminarily dried on the surface by the electric heating plate 12 before entering the drying box 11 for drying. When the electric heating plate 12 needs to be maintained or replaced, the operating shaft 14 is pulled. After the operating shaft 14 is subjected to force, it will drive the sliding column 13 on its side wall to move. Then the fixed shaft 15 on the side wall of the sliding column 13 follows the displacement and drives the slip ring 22 on its outer wall to enter the inner platform 17. Then, its surface or the inclined edge 21 on the side wall of the block 19 pushes the block 19 to enter. The inside of the card block 19, then the operating shaft 14 is pulled out, the slip ring 22 randomly slides on the outer wall of the fixed shaft 15 and fits with the card plate 16, and pushes the card block 19 again to drive the card plate 16 to release the engagement state from the inside of the inner platform 17, and pushes the card block 19 through the spring 20 so that the card block 19 can be reset and maintain the stability of the engagement state. When it is necessary to dry a plastic package with higher temperature requirements and a larger printing area, the original heating plate can be easily removed and replaced with a heating plate with higher power and more suitable size to meet new production requirements and improve the adaptability of the equipment to different production tasks.
