Description

Technical Field

[0001] This utility model relates to the field of corrugated paper production technology, specifically to a dryer for corrugated paper production. Background Technology

[0002] After corrugated paper is formed, it still contains moisture, and the glue in the multi-layer cardboard is not completely dry after bonding. Therefore, a drying device is needed to dry the corrugated paper to ensure its stability after forming. For example, a corrugated paper drying device with announcement number CN214701630U includes a worktable and a drive unit. A conveyor belt is wound on the worktable, and a drying device is provided on one side of the worktable. The drying device includes a drying lamp facing the conveyor belt. The drive unit drives the conveyor belt to transport the paper. Multiple mounting seats are provided on the surface of the conveyor belt. The mounting seats are arranged sequentially along the length of the conveyor belt. A support seat is detachably connected to the mounting seat. The side of the support seat away from the mounting seat is used to place the corrugated paper. The drying lamp faces the side of the support seat away from the mounting seat. The corrugated paper is placed on the side of the support away from the installation point. The support raises the corrugated paper until it is directly facing the drying lamp. Because the bottom of the corrugated paper is not completely in contact with the support, the contact area between the hot air and the corrugated paper is increased, resulting in more uniform drying and improving the drying effect of the corrugated paper drying device. However, this corrugated paper drying device still has the following drawbacks in actual use:

[0003] Traditional drying devices mostly dry only one side during the drying process, resulting in low drying efficiency. Furthermore, during the conveyor belt transport of corrugated paper, the hot air drying causes the corrugated paper to stick to the dry wire, which not only affects subsequent removal but also damages the surface of the corrugated paper. To address these issues, there is an urgent need for innovative designs based on the existing dry wire drying devices. Utility Model Content

[0004] The purpose of this utility model is to provide a dryer for corrugated paper production, in order to solve the problems mentioned in the background art. Traditional drying devices mostly dry only one side during the drying process, resulting in low drying efficiency. Furthermore, during the conveying of corrugated paper on the dryer conveyor belt, the hot air drying causes the corrugated paper to stick to the dryer, which not only affects the subsequent removal but also damages the surface of the corrugated paper.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dry wire drying device for corrugated paper production, including a support frame, a drive motor installed on the side of the support frame, and the drive motor drives the dry wire conveyor belt to convey the wire.

[0006] It also includes: a drying box, fixed above the support frame, a hot air blower installed on the top of the drying box, and the output shaft of the hot air blower is connected to the middle of the air supply pipe, and the air supply pipe is fixed to the inner top surface of the drying box. A fixed pipe and a connecting pipe are provided below the air supply pipe, and air nozzles are fixed at equal intervals on the fixed pipe and the connecting pipe.

[0007] A guiding mechanism is located on the inner side of the support frame. The guiding mechanism is used to guide the corrugated paper to align and prevent it from sticking together.

[0008] Preferably, both the fixed pipe and the connecting pipe are connected to the gas supply pipe, and the fixed pipe has a "C" shaped structure and the connecting pipe has an "O" shaped structure. By alternating the fixed pipe and the connecting pipe, the corrugated paper can be dried completely.

[0009] Preferably, the fixed pipe and the connecting pipe are arranged alternately, and the bottom of the fixed pipe and the connecting pipe are both located between the upper and lower surfaces of the dry conveyor belt. The gas entering the fixed pipe and the connecting pipe can eventually be discharged from the jet nozzle and blown onto the corrugated paper.

[0010] Preferably, the guiding mechanism includes a movable shaft that passes through the inside of the connecting pipe, and a fixed block is provided at one end of the movable shaft. The fixed blocks are evenly distributed on the movable shaft, and the movable shaft can be driven to rotate when the fixed blocks are blown by gas.

[0011] Preferably, the movable shaft and the connecting pipe are rotatably connected, and a connecting rod is fixed at the other end of the movable shaft. The connecting rod is inclined, and when the movable shaft rotates, it drives the connecting rod to rotate synchronously. When the connecting rod rotates, it can contact the guide plate.

[0012] Preferably, the movable shaft rotates through the support frame, and the end of the connecting rod away from the movable shaft is close to the guide plate. The bottom of the guide plate is attached to the edge of the dry wire conveyor belt. The connecting rod can push the guide plate to slide on the dry wire conveyor belt. The position of the corrugated paper can be adjusted by the two guide plates that are close to each other.

[0013] Preferably, the guide plate has an arc-shaped structure on the side near the support frame, and a movable rod is fixed on the arc surface of the guide plate. The movable rod slides through the support frame, and a spring is wound around the outside of the movable rod. When the guide plate moves, it drives the movable rod to slide on the support frame. After the guide plate is no longer pushed, it returns to its original position due to the elasticity of the spring.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the dryer for corrugated paper production can achieve simultaneous drying of both sides of the corrugated paper, and the position of the corrugated paper can be adjusted by pushing and vibrating during the drying process to avoid adhesion between the corrugated paper and the dryer conveyor belt. The specific details are as follows:

[0015] 1. The hot air generated by the hot air blower is transferred to the fixed pipe and the connecting pipe respectively, and finally sprayed out from the nozzle onto the corrugated paper for drying. Since the lower ends of the fixed pipe and the connecting pipe are below the dry wire conveyor belt, the corrugated paper can be dried on both sides.

[0016] 2. When the gas enters the connecting pipe, it can contact the fixed block and drive the movable shaft to rotate synchronously with the connecting rod. When the connecting rod rotates, it can contact the guide plate and push it to slide on the dry wire conveyor belt. The two guide plates that are close to each other can adjust the position of the corrugated paper during the conveying process, ensuring that it is in the middle position of the dry wire conveyor belt and improving the drying efficiency.

[0017] Furthermore, the connecting rod can come into contact with the dry wire conveyor belt during rotation, causing its surface to vibrate, which further prevents the corrugated paper from sticking to the dry wire conveyor belt. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 The present invention provides the following technical solution:

[0027] Example 1: To address the problems existing in the prior art, this example provides a dryer for corrugated paper production, comprising a support frame 1, a drive motor 2 mounted on the side of the support frame 1, and the drive motor 2 driving the dryer conveyor belt 3; further comprising: a drying chamber 4 fixed above the support frame 1, a hot air blower 5 mounted on the top of the drying chamber 4, the output shaft of the hot air blower 5 being connected to the middle of an air supply pipe 6, the air supply pipe 6 being fixed to the inner top surface of the drying chamber 4, a fixing pipe 7 and a connecting pipe 9 being provided below the air supply pipe 6, and air nozzles 8 being fixed at equal intervals on the fixing pipe 7 and the connecting pipe 9; and a guiding mechanism located inside the support frame 1, used to guide the corrugated paper to align and prevent sticking.

[0028] Existing drying equipment mostly only dries one side during the drying process, resulting in low drying efficiency, such as Figures 1-3 As shown, both the fixed pipe 7 and the connecting pipe 9 are connected to the air supply pipe 6. The fixed pipe 7 has a "C" shape, and the connecting pipe 9 has an "O" shape. The fixed pipe 7 and the connecting pipe 9 are alternately arranged, and the bottom of both the fixed pipe 7 and the connecting pipe 9 is located between the upper and lower surfaces of the dry wire conveyor belt 3. The corrugated paper to be dried is placed on the dry wire conveyor belt 3 and conveyed. Then, the hot air generated by the hot air blower 5 is conveyed to the air supply pipe 6 and then to the fixed pipe 7 and the connecting pipe 9 respectively. Finally, it is sprayed out from the nozzle 8 and blown onto the corrugated paper for drying. Since the lower ends of the fixed pipe 7 and the connecting pipe 9 are below the dry wire conveyor belt 3, the corrugated paper can be dried on both sides.

[0029] Example 2: In existing methods, during the conveying of corrugated paper on the dryer conveyor belt 3, the hot air drying process causes the corrugated paper to stick to the dryer, which not only affects subsequent removal but also damages the surface of the corrugated paper. Therefore, this example uses the following technical solution, such as... Figures 4-6As shown, the guiding mechanism includes a movable shaft 10 that passes through the connecting pipe 9, and a fixed block 11 is provided at one end of the movable shaft 10, with the fixed blocks 11 evenly distributed on the movable shaft 10; the movable shaft 10 and the connecting pipe 9 are rotatably connected, and a connecting rod 12 is fixed at the other end of the movable shaft 10, and the connecting rod 12 is inclined; the movable shaft 10 rotatably passes through the support frame 1, and the end of the connecting rod 12 away from the movable shaft 10 is close to the guide plate 14, and the bottom of the guide plate 14 is attached to the edge of the dry mesh conveyor belt 3; the side of the guide plate 14 near the support frame 1 has an arc surface structure, and a movable rod 13 is fixed on the arc surface of the guide plate 14, and the movable rod 13 slides through the support frame 1, while a spring is wound around the outside of the movable rod 13; when gas enters the connecting pipe 9 When the internal part is in contact with the fixed block 11, it drives the movable shaft 10 to rotate. The movable shaft 10 drives the connecting rod 12 to rotate synchronously. When the connecting rod 12 rotates, it can contact the guide plate 14 and push the guide plate 14 to slide on the dry wire conveyor belt 3. The two guide plates 14 that are close to each other have the function of adjusting the position of the corrugated paper during the conveying process, ensuring that it is in the middle position of the dry wire conveyor belt 3, improving the drying efficiency, and also preventing the corrugated paper from sticking to the dry wire conveyor belt 3. When the guide plate 14 moves, it drives the movable rod 13 to slide on the support frame 1. When the guide plate 14 is not pushed, it returns to its original position through the elasticity of the spring. In addition, the connecting rod 12 can contact the dry wire conveyor belt 3 during rotation, causing its surface to vibrate, which further prevents the corrugated paper from sticking to the dry wire conveyor belt 3.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
