Technical Field

[0001] This invention relates to the field of drying systems, specifically a drying system for foam-packaged products. Background Technology

[0002] Foam packaging is a type of packaging product made from foam materials, typically used to protect the contents. Foam packaging usually refers to packaging products made from expandable polystyrene (EPS) raw materials through heat processing using molds, and the resulting products are commonly known as "foam".

[0003] In the prior art, Chinese patent document CN106091662B discloses a drying device for packaging foam, which solves the problems of low efficiency, inconvenient operation, and troublesome loading and unloading of current drying equipment. However, in practical applications, after the foam packaging products in the drying equipment are dried, the workers need to remove the dried products one by one, and put the products into the drying equipment one by one when drying again. This makes loading and unloading of products take a long time each time the products are dried, resulting in a reduction in the drying efficiency of foam packaging products.

[0020] 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.

[0021] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a foam packaging product drying system.

[0022] In one typical implementation of this application, such as Figures 1-6As shown, a foam packaging product drying system includes a drying chamber 1, which contains a heating component for drying (existing technology). A preheating chamber 2 is fixedly connected to the outer wall of the drying chamber 1. A feed plate 3 is fixedly connected to one end of the preheating chamber 2, and two first baffles 4 are rotatably connected to one end of the preheating chamber 2. The feed plate 3 fits against the lower end of the upper first baffle 4. A first pull rope 5 is fixedly connected to one side of the upper first baffle 4, and one end of the first pull rope 5 extends to the outside of the preheating chamber 2. Connection holes 6 are provided on both sides of the lower end of the drying chamber 1, and a second connection hole 6 is provided at the upper end of the connection hole 6. The system comprises a movable groove 7 and a rotating groove 10. A second baffle 8 is slidably connected to the inner cavity of the movable groove 7. The second baffle 8 is adapted to a connecting hole 6. Several second pull ropes 9 are fixedly connected to the top of the second baffle 8. One end of each pull rope 9 passes through the drying chamber 1 and is wound around a rotating shaft 11 inside the rotating groove 10. The rotating shaft 11 is rotatably connected to the rotating groove 10. A first belt assembly 12 is fixedly sleeved at one end of the rotating shaft 11 extending outside the drying chamber 1. A second belt assembly 13 is fixedly sleeved at one end of the first belt assembly 12. A first spur gear 14 is fixedly sleeved at one end of the second belt assembly 13. The first spur gear 14 is located outside the drying chamber 1 and is rotatably connected to the drying chamber 1. One end of the first spur gear 14 meshes with a half gear 15. One end of the drying chamber 1 is fixedly connected to a motor 16. The output shaft of the motor 16 is fixedly sleeved with the half gear 15. The feed plate 3 is fixedly connected to the connecting hole 6. The feed plate 3 forms a certain angle with the horizontal plane. One end of the first pull rope 5 extending to the outside of the preheating chamber 2 is fixedly connected to a handle. The top of the preheating chamber 2 is fixedly connected to a first spring. One end of the first spring is fixedly connected to the upper first baffle 4. The top of the second baffle 8 is fixedly connected to a second spring. One end of the second spring is fixedly connected to the top of the first moving groove 7. In use, the preheating chamber 2 is fixedly connected to the outer wall of the drying chamber 1. One end of the preheating chamber 2 is fixedly connected to the feed plate 3, so that the relative positions of the drying chamber 1, the preheating chamber 2 and the feed plate 3 are fixed. Two first baffles 4 are rotatably connected to one end of the preheating chamber 2. The upper first baffle... A first pull rope 5 is fixedly connected to one side of plate 4. One end of the first pull rope 5 extends to the outside of the preheating box 2, so that when the operator pulls the first pull rope 5, it will cause the upper first baffle 4 to rotate, thereby causing a row of foam packages arranged on the upper end of the feeding plate 3 to slide together between the first baffle 4 and the drying box 1. Then, after releasing the pull rope 5, the first baffle 4 returns to its original position, and the operator arranges another row of foam packages to be dried on the upper end of the feeding plate 3, reducing the opening time of the first baffle 4 and reducing the heat loss inside the preheating box 2. Connection holes 6 are provided on both sides of the lower end of the drying box 1. A first moving groove 7 and a rotating groove 10 are provided at the upper end of the connection hole 6. A second baffle 8 is slidably connected to the inner cavity of the first moving groove 7. The second baffle 8 is adapted to the connection hole 6. Several second pull ropes 9 are fixedly connected to the top of the second baffle 8. One end of the second pull rope 9 extends through the drying box 1 to the rotating groove 10 and is wound with a rotating shaft 11.A rotating shaft 11 is rotatably connected to a rotating groove 10. A first belt assembly 12 is fixedly sleeved at one end of the rotating shaft 11 extending outside the drying chamber 1. A second belt assembly 13 is fixedly sleeved at one end of the first belt assembly 12. A first spur gear 14 is fixedly sleeved at one end of the second belt assembly 13. A half gear 15 meshes with one end of the first spur gear 14. A motor 16 is fixedly connected to one end of the drying chamber 1. The output shaft of the motor 16 is fixedly sleeved with the half gear 15. The first spur gear 14 and the second spur gear 19 are located on opposite sides of the half gear 15, respectively. When the operator starts the motor 16, the motor 16 drives the half gear 15 to rotate, causing the half gear 15 to rotate through the first spur gear 14, the second belt assembly 13, and the first belt assembly 10. Group 12 drives the rotating shaft 11 to rotate, causing the rotating shaft 11 to wind up the second pull rope 9. This causes the second pull rope 9 to move the second baffle 8 into the inner cavity of the first moving groove 7. Then, the foam packaging between the first baffle 4 and the drying chamber 1 slides through the connecting hole 6 into the drying chamber 1 for drying. After drying in the drying chamber 1, the foam packaging falls from the other side of the drying chamber 1 into the preheating chamber 2. After the second baffle 8 rises to the top of the first moving groove 7, the first spur gear 14 and the half gear 15 no longer mesh, losing their pulling force on the second baffle 8. At this time, the second baffle 8 falls downwards under its own weight, causing the inner cavity of the drying chamber 1 to seal again, drying the foam packaging and allowing it to dry completely. The self-loading and unloading system improves the loading and unloading speed of foam packaging, reduces the waiting time of the drying system, and increases the drying efficiency of the foam packaging. The feeding plate 3 is fixedly connected to the connecting hole 6 at a certain angle to the horizontal plane. This allows the foam packaging placed on top of the feeding plate 3 to slide down towards the connecting hole 6 under its own weight, thus enabling the neatly arranged foam packaging to slide into the drying chamber 1. This allows workers to arrange multiple foam packages one by one and feed them all into the drying chamber 1 at once while waiting for the foam packaging to dry in the drying system, reducing the waiting time of the drying system during loading and unloading, improving the drying efficiency of the foam packaging, and reducing the burden on the drying system. The waiting time is reduced, saving energy. A handle is fixedly connected to one end of the first pull rope 5 extending to the outside of the preheating box 2, making the first pull rope 5 easy to pull and restricting its movement. A first spring is fixedly connected to the top of the preheating box 2, with one end of the first spring fixedly connected to the first baffle 4. This allows the first baffle 4 to quickly return to its original position under its own weight and the action of the first spring after the pull of the first pull rope 5 is removed. A second spring is fixedly connected to the top of the second baffle 8, with one end of the second spring fixedly connected to the top of the first moving groove 7. This allows the second baffle 8 to quickly return to its original position under the action of the second spring after the pulling force is removed, reducing the loss of drying gas inside the drying box 1.

[0023] As a preferred embodiment of this example, please refer to the appendix. Figures 1-3A conveyor belt assembly 17 is rotatably connected to the lower end of the preheating box 2. A third belt assembly 18 is fixedly sleeved at one end of the conveyor belt assembly 17 extending outside the preheating box 2. A second spur gear 19 is fixedly sleeved at one end of the third belt assembly 18. The second spur gear 19 meshes with a half gear 15. Several holes are opened in the middle of the feed plate 3 located between the first baffle 4 and the drying box 1. The first spur gear 14 and the second spur gear 19 are respectively located on both sides of the half gear 15. The drying box 1 is located at the upper end of the conveyor belt assembly 17. The first baffle 4 at the lower end is located on one side of the conveyor belt assembly 17. The diameter of the first spur gear 14 is smaller than the diameter of the second spur gear 19 and the half gear 15. A guide plate is fixedly connected to the bottom end of the preheating box 2. The guide plate is located on the upper part of the conveyor belt assembly 17. At the end, the guide plate is inclined relative to the horizontal plane and tilts towards the conveyor belt assembly 17. The conveyor belt assembly 17 is rotatably connected to the lower end of the preheating box 2. A third belt assembly 18 is fixedly sleeved at one end of the conveyor belt assembly 17 extending outside the preheating box 2. A second spur gear 19 is fixedly sleeved at one end of the third belt assembly 18. The second spur gear 19 meshes with a half gear 15. Several holes are opened in the middle of the feed plate 3 located between the first baffle 4 and the drying box 1, so that the dried foam packaging falling from the drying box 1 will fall to one end of the conveyor belt assembly 17. Then, when the half gear 15 drives the second spur gear 19 to rotate, the second spur gear 19 drives the conveyor belt assembly 17 to rotate through the third belt assembly 18, transporting the foam packaging at the upper end of the conveyor belt assembly 17. After being placed between the first baffle 4 and the drying chamber 1, the foam packaging is removed, extending its remaining time in the preheating chamber 2. This allows residual heat on the dried foam packaging to dissipate into the preheating chamber 2, and then escape through the holes in the feed plate 3 to the upper end, preheating the foam between the upper first baffle 4 and the drying chamber 1. This preheating of the dried foam packaging is utilized, which also improves the drying efficiency. The first sprocket 14 and the second sprocket 19 are located on both sides of the half gear 15, causing the half gear 15 to drive the first sprocket 14 and the second sprocket 19 to rotate alternately. The drying chamber 1 is located at the upper end of the conveyor belt assembly 17, and the lower first baffle 4 is located on one side of the conveyor belt assembly 17, ensuring the drying chamber 1... The foam packaging that falls inside will land on the upper end of the conveyor belt assembly 17. Since the diameter of the first spur gear 14 is smaller than the diameters of the second spur gear 19 and the half gear 15, the first spur gear 14 rotates faster, which can quickly raise the second baffle 8, reducing the connection time between the drying chamber 1 and the preheating chamber 2, thereby reducing the heat loss in the drying chamber 1. A guide plate is fixedly connected to the bottom of the preheating chamber 2. The guide plate is located at the upper end of the conveyor belt assembly 17 and is inclined relative to the horizontal plane. The guide plate is inclined towards the conveyor belt assembly 17 to ensure that the foam packaging falling inside the drying chamber 1 will be moved by the conveyor belt assembly 17, avoiding the situation where small foam packaging gets stuck in the gap between the conveyor belt assembly 17 and the preheating chamber 2 and cannot move.

[0024] As a preferred embodiment of this example, please refer to the appendix. Figures 4-6A second movable groove 20 is provided on one side of the drying oven 1, and a third movable groove 21 is provided on both sides of the drying oven 1. The second movable groove 20 is connected to the third movable groove 21 on the same side. A turntable 22 is rotatably connected to the inner cavity of the second movable groove 20. The rotating shaft of the turntable 22 passes through to the outside of the drying oven 1 and is fixedly connected to a second spur gear 19. A first connecting rod 23 is rotatably connected to one end of the turntable 22. A second connecting rod 24 is rotatably connected to the lower end of the first connecting rod 23. A third connecting rod 25 is fixedly connected to both ends of the second connecting rod 24. The third connecting rod 25 passes through the third movable groove 21 to the inner cavity of the drying oven 1. The third connecting rod 25 is slidably connected in the third movable groove 21. A drying rack 26 is rotatably connected to both ends of the third connecting rod 25 inside the drying oven 1. The drying rack 26 is adapted to the connecting hole 6. A return spring 27 is fixedly connected to both ends of the drying rack 26. A fixing frame 28 is fixedly connected to the lower end of the return spring 27. The fixing frame 28 is fixedly connected to the third connecting rod 25. First push plates 29 are fixedly connected to both sides of the bottom of the drying box 1. Two second push plates 31 are fixedly connected to the top of the drying box 1. The side of the drying rack 26 is arc-shaped. The first push plate 29 is in contact with one side of the drying rack 26, pushing one side of the drying rack 26 towards the connecting holes 6 on both sides of the drying box 1. The two second push plates 31 are in contact with one side of each of the two drying racks 26. The first push plate 29 is located on the side of the two drying racks 26 that is close to each other, and the two second push plates 31 are located on the side of the two drying racks 26 that is far apart. On the other side, several push rods 30 are fixedly connected to the bottom of the drying chamber 1. The side of the push rods 30 away from the feed plate 3 is adapted to the side of the drying rack 26 near the center of the drying chamber 1. The push rods 30 can be inserted into the drying rack 26. The push rods 30 are not in contact with the drying rack 26 and the third connecting rod 25. The upper end of the push rods 30 extends into the interior of the drying rack 26. A second moving groove 20 is opened on one side of the drying chamber 1, and a third moving groove 21 is opened on both sides of the drying chamber 1. The second moving groove 20 is connected to the third moving groove 21 on the same side. A turntable 22 is rotatably connected to the inner cavity of the second moving groove 20. The rotating shaft of the turntable 22 passes through the outside of the drying chamber 1 and is fixedly connected to the second spur gear 19. A first connecting rod 23 is rotatably connected to one end of the turntable 22. The lower end of the 3 is rotatably connected to a second connecting rod 24. Both ends of the second connecting rod 24 are fixedly connected to third connecting rods 25. When the second spherical gear 19 rotates, it drives the turntable 22 to rotate. The turntable 22 moves the second connecting rod 24 and the third connecting rod 25 through the first connecting rod 23. The third connecting rod 25 passes through the third moving groove 21 to the inner cavity of the drying chamber 1. The third connecting rod 25 is slidably connected in the third moving groove 21. Both ends of the third connecting rod 25 in the drying chamber 1 are rotatably connected to drying racks 26. The drying racks 26 are adapted to the connecting holes 6. The third moving groove 21 restricts the movement of the third connecting rod 25 and the drying racks 26, so that the foam packaging that enters the drying chamber 1 through the connecting holes 6 will fall into the drying racks 26.Next, the third connecting rod 25 moves the foam packaging within the drying chamber 1 via the drying rack 26. Return springs 27 are fixedly connected to both ends of the drying rack 26, and a fixing frame 28 is fixedly connected to the lower end of each return spring 27. The fixing frame 28 is fixedly connected to the third connecting rod 25. First push plates 29 are fixedly connected to both sides of the bottom of the drying chamber 1, and two second push plates 31 are fixedly connected to the top of the drying chamber 1. The sides of the drying rack 26 are arc-shaped. The first push plates 29 are in contact with one side of the drying rack 26, pushing the drying rack 26 towards the connecting holes 6 on both sides of the drying chamber 1. The two second push plates 31 are in contact with one side of each of the two drying racks 26, with the first push plates 29 positioned close to the two drying racks 26. On one side, two second push plates 31 are located on opposite sides of the two drying racks 26. This allows the third connecting rod 25 to move the drying rack 26 to the bottom of the drying chamber 1. One end of the drying rack 26 is then lifted by the first push plate 29, causing the drying rack 26 to rotate around the third connecting rod 25. This facilitates the entry and exit of foam packaging within the drying rack 26. After the third connecting rod 25 moves the drying rack 26 upwards, the drying rack 26 loses the effect of the first push plate 29 and returns to its original position under the action of the return spring 27. This stabilizes the position of the foam packaging within the drying rack 26, preventing it from falling off during movement. This allows the drying rack 26 to hold various sizes of foam packaging, improving its practicality. After the third connecting rod 25 moves the two drying racks 26 to the top, they approach the feed plate 3. One side of the drying rack 26 is pushed by the second push plate 31, causing the drying rack 26 to flip. Then, the foam packaging inside the drying rack 26 falls into the drying rack 26 on the side away from the feed plate 3. After that, the third connecting rod 25 and the drying rack 26 are driven to move downwards. The foam in the drying rack 26 on the other side of the drying box 1 falls through the connecting hole 6 to the upper end of the conveyor belt assembly 17. The foam packaging is put back into the drying rack 26 on one side of the drying box 1 for drying, causing the foam packaging to move up and down in the inner cavity of the drying box 1. The automatic drying process improves the drying effect. Several push rods 30 are fixedly connected to the bottom of the drying chamber 1 on the other side. The side of the push rods 30 away from the feed plate 3 is matched with the side of the drying rack 26 closest to the center of the drying chamber 1. The push rods 30 can be inserted into the drying rack 26, but they do not touch the drying rack 26 or the third connecting rod 25. The upper end of the push rods 30 extends into the interior of the drying rack 26, allowing the push rods 30 to help the foam packaging inside the drying rack 26 fall out of the drying chamber 1, ensuring smooth feeding and unloading of the foam packaging.

[0025] Working principle of this invention: In use, when the operator pulls the first rope 5, it drives the upper first baffle 4 to rotate. This allows the operator to arrange multiple foam packages one by one and then feed them all into the drying chamber 1 at once while waiting for the foam packages to dry in the drying system. This reduces the waiting time of the drying system during the loading and unloading of foam packages, improves the drying efficiency of the foam packages, and saves energy. The row of foam packages arranged at the top of the feeding plate 3 slides together between the first baffle 4 and the drying chamber 1. Then, the operator releases the pull on the first rope 5, and the first baffle 4 returns to its original position. The operator then arranges another row of foam packages to be dried at the top of the feeding plate 3, reducing the opening time of the first baffle 4 and reducing heat loss in the preheating chamber 2. After starting the motor 16, the motor 16 drives the half gear 15 to rotate, so that the half gear 15 passes through the first sprocket 14 and the second belt... The belt assembly 13 and the first belt assembly 12 drive the rotating shaft 11 to rotate, causing the rotating shaft 11 to wind up the second pull rope 9. This causes the second pull rope 9 to move the second baffle 8 into the inner cavity of the first moving groove 7. Then, the foam packaging between the first baffle 4 and the drying chamber 1 slides through the connecting hole 6 into the drying chamber 1 for drying. After drying in the drying chamber 1, the foam packaging falls from the other side of the drying chamber 1 into the preheating chamber 2. After the second baffle 8 rises to the top of the first moving groove 7, the first spur gear 14 and the half gear 15 no longer mesh, losing the pulling force on the second baffle 8. At this time, the second baffle 8 falls downward under its own weight, causing the inner cavity of the drying chamber 1 to be sealed again, drying the foam packaging. This allows the foam packaging in the drying chamber 1 to be loaded and unloaded automatically, increasing the loading and unloading speed of the foam packaging, reducing the waiting time of the drying system during operation, and improving the drying efficiency of the foam packaging.

[0026] The dried foam packaging that falls from the drying chamber 1 will fall to one end of the conveyor belt assembly 17. Then, the half gear 15 drives the second spur gear 19 to rotate. The second spur gear 19 drives the conveyor belt assembly 17 to rotate through the third belt assembly 18. The foam packaging at the top of the conveyor belt assembly 17 is transported to the space between the first baffle 4 and the drying chamber 1 and then taken out. This extends the time that the dried foam packaging stays in the preheating chamber 2, so that the residual heat on the dried foam packaging can be dissipated into the preheating chamber 2. Then, it escapes through the holes in the feed plate 3 to the top to preheat the foam to be dried between the first baffle 4 and the drying chamber 1. The preheating of the dried foam packaging is utilized, which can also improve the drying efficiency of the foam packaging.

[0027] When the second spur gear 19 rotates, it drives the turntable 22 to rotate, causing the turntable 22 to move via the first connecting rod 23, which in turn drives the second connecting rod 24 and the third connecting rod 25. The third moving groove 21 restricts the movement of the third connecting rod 25 and the drying rack 26, allowing the foam packaging that enters the drying chamber 1 through the connecting hole 6 to fall into the drying rack 26. Then, the third connecting rod 25 moves the foam packaging within the drying chamber 1 via the drying rack 26. After the drying rack 26 is moved to the bottom of the drying chamber 1 by the third connecting rod 25, one end of the drying rack 26 is lifted by the first push plate 29, causing the drying rack 26 to rotate around the third connecting rod 25. This facilitates the entry and exit of the foam packaging within the drying rack 26, enabling automatic loading and unloading of the foam packaging and improving the drying efficiency of the foam packaging. After the drying rack 26 moves upward with the third connecting rod 25, the drying rack 26 loses the effect of the first push plate 29 and returns to its original position under the action of the return spring 27. The foam packaging inside the drying rack 26 is positioned stably, preventing it from falling off during rack movement. This allows for the placement of various sizes of foam packaging within the drying rack 26, improving its practicality. After the third connecting rod 25 lifts the drying rack 26 to the top, the drying rack 26 on one side of the drying chamber 1 is pushed by the second push plate 31, causing the third connecting rod 25 to flip. The foam packaging then falls from the drying rack 26 on one side to the drying rack 26 on the other side of the drying chamber 1. Subsequently, the third connecting rod 25 and the drying rack 26 are moved downwards, and the foam packaging on the drying rack 26 on the other side of the drying chamber 1 falls through the connecting hole 6 to the upper end of the conveyor belt assembly 17. The foam packaging is then placed back into the drying rack 26 on one side of the drying chamber 1 for drying. This allows the foam packaging to move up and down within the drying chamber 1 for drying, resulting in better drying. The push rod 30 helps the foam packaging in the drying rack 26 fall out of the drying chamber 1, ensuring smooth loading and unloading of the foam packaging.
