Description

Technical Field

[0001] This utility model relates to the papermaking field, specifically a high-efficiency circulating drying device for papermaking. Background Technology

[0002] Paper is a material with extremely wide applications, covering almost every aspect of our lives. From daily writing and reading to industrial production and artistic creation, paper plays an important role.

[0003] A specific example of an existing high-efficiency circulating drying device for papermaking can be found in application number CN202320823948.1, which describes a rapid drying device for a printing press. The device features a drying chamber with symmetrically welded fixing plates at both ends. A geared motor is fixedly installed on the outer wall of the fixing plate at the end furthest from the drying chamber. The output end of the geared motor passes through the fixing plate and is connected to a conveyor belt. An adsorption box is fixedly installed inside the drying chamber, adhering to the side of the conveyor belt. An adsorption hole is opened on one side of the top of the adsorption box. This invention has the following advantages: the printed paper is transported to the drying chamber via the conveyor belt; the operation of the air inlet fan causes the adsorption box to continuously intake air through the adsorption hole, adsorbing and fixing the printed paper onto the conveyor belt; the air inlet fan exhausts air through the air outlet pipe, causing the airflow around the heating tube to flow downwards, thereby accelerating the drying of the printed paper. Simultaneously, it ensures uniform heat circulation and flow within the drying chamber, preventing heat waste. When the outer surface of the conveyor belt passes the brush head, the brush head removes impurities from the conveyor belt's surface.

[0004] The aforementioned device does not include a mechanism for accelerating the circulating drying process. Since the paper needs to be conveyed and dried through a conveying device during the drying process, the short conveying distance makes it easy for incomplete drying to occur. Therefore, a high-efficiency circulating drying device for papermaking is proposed to address the above problems. Utility Model Content

A first gear 11 is fixedly connected to the top of the first motor 10, and a second gear 12 is meshed with the first gear 11. A first transmission rod 13 is fixedly connected to the bottom of the second gear 12. A first sleeve block 14 is sleeved on the outer side of the bottom of the first transmission rod 13, and the first transmission rod 13 is rotatably connected to the first sleeve block 14. The bottom of the first sleeve block 14 is fixedly connected to the drying device body 2, and the inner wall of the first sleeve block 14 is circular.

[0030] During operation, one end of the paper is placed on the top of the conveying device 1 and the conveying device 1 is started, which moves the paper into the drying device body 2. At the same time, the drying device body 2 is started and the first motor 10 at the top of the drying device body 2 is started, which drives the first gear 11 to rotate. When the first gear 11 rotates, it drives the second gear 12 and the first transmission rod 13 to rotate at the same time, and the bottom end of the first transmission rod 13 rotates along the inside of the first sleeve block 14.

[0031] Furthermore, a first pulley 15 is fixedly connected to the top of the first gear 11, and a second pulley 17 is driven to one end of the outer side of the first pulley 15. A first transmission belt 16 is driven to the other end of the second pulley 17. A third pulley 18 is fixedly connected to the top of the second gear 12. A fourth pulley 20 is driven to one end of the outer side of the third pulley 18. A second transmission belt 19 is driven to the other end of the fourth pulley 20. A second rotating rod 21 is also fixedly connected to the bottom of the first transmission belt 16 and the second transmission belt 19. The second rotating rod 21 is a circular rod design.

[0032] During operation, the first gear 11 rotates, causing the first pulley 15 and the second pulley 17 to rotate simultaneously. The second pulley 17 also causes the first transmission belt 16 to rotate. Simultaneously, when the second gear 12 rotates, it causes the third pulley 18 and the fourth pulley 20 to rotate simultaneously.

[0034] During operation, the second rotating rod 21 rotates, causing the rotating block 22 to rotate along the inside of the second set of blocks 23. The first fixed frame 24 is used to fix and support the position of the second set of blocks 23. At the same time, the second rotating rod 21 drives the fan 25 to rotate. When the fan 25 rotates, it will accelerate the circulation of hot air inside the drying device body 2, thereby accelerating the drying effect.

[0035] Furthermore, a winding and unwinding assembly is provided on the right side of the conveying device 1. The winding and unwinding assembly includes a winding roller 26.

One end of an insert block 28 is sleeved on the outside of the guide rod 27, and the guide rod 27 is slidably connected to the insert block 28. The inner wall of the insert block 28 is circular.

[0036] During operation, the inserts 28 at both ends of the take-up roller 26 are pressed towards the position of the take-up roller 26, causing the inserts 28 to retract and move along the outside of the guide rod 27.

[0037] Furthermore, the upper and lower ends of the front and rear ends of the take-up roller 26 are also fixedly connected to one end of the return spring 29, and the other end of the return spring 29 is fixedly connected to the insert block 28.

The inner walls of both the insert block 28 and the fixed block 30 are square.

[0038] During operation, the insertion block 28 moves, which will compress the return spring 29 to retract. At the same time, the insertion block 28 moves outward along the inside of the fixed block 30 until the insertion block 28 is completely removed from the inside of the fixed block 30, at which point the take-up roller 26 can be removed.

[0039] Furthermore, the front and rear ends of the right side of the conveying device 1 are also fixedly connected to the second fixed frame 31. The front end of the second fixed frame 31 at the front position of the conveying device 1 is fixedly connected to the second motor 32. The rear end of the second motor 32 passes through the second fixed frame 31 and is fixedly connected to the fixed rod 33. The rear end of the fixed rod 33 is fixedly connected to the fixed block 30 at the front position of the take-up roller 26. The rear end of the fixed block 30 at the rear position of the take-up roller 26 is fixedly connected to the third transmission rod 35. The outer side of the rear end of the third transmission rod 35 is fitted with a third sleeve block 34, and the third transmission rod 35 is rotatably connected to the third sleeve block 34. The rear end of the third sleeve block 34 is fixedly connected to the second fixed frame 31. The inner wall of the third sleeve block 34 is circular.

[0040] During operation, one end of the dried paper is wound around the outside of the take-up roller 26. The second motor 32 at the side of the second fixed frame 31 is started, which drives the fixed rod 33 to rotate. At the same time, the fixed block 30 at the front end of the take-up roller 26 rotates, and the take-up roller 26 rotates synchronously. When the take-up roller 26 rotates, it drives the third transmission rod 35 to rotate along the inside of the third set of blocks 34.

[0041] Working Principle: During drying, one end of the paper is placed on top of the conveyor device 1, and the conveyor device 1 is started, moving the paper into the drying device body 2. Simultaneously, the drying device body 2 is started, along with the first motor 10 at its top, which drives the first gear 11 to rotate. When the first gear 11 rotates, it drives the second gear 12 and the first transmission rod 13 to rotate simultaneously. The bottom end of the first transmission rod 13 rotates along the inside of the first sleeve block 14. When the first gear 11 rotates, it drives the first pulley 15 and the second pulley 17 to rotate simultaneously. The second pulley 17 drives the first transmission belt 16 to rotate. Simultaneously, when the second gear 12 rotates, it drives the third pulley 18 and the fourth pulley 20 to rotate simultaneously. The fourth pulley 20 drives the second transmission belt 19 to rotate. When the first transmission belt 16 and the second transmission belt 19 rotate, they drive the second rotating rod 21 to rotate. When the second rotating rod 21 rotates, it drives the rotating block 22 to rotate along the inside of the second sleeve block 23. The first fixing frame 24 is used to fix and support the position of the second block 23. At the same time, the second rotating rod 21 drives the fan 25 to rotate. When the fan 25 rotates, it will accelerate the circulation of hot air inside the main body 2 of the drying device, thereby accelerating the drying effect. Then, one end of the dried paper is wound around the outside of the take-up roller 26. The second motor 32 at the side of the second fixing frame 31 is started, which drives the fixing rod 33 to rotate. At the same time, it drives the fixing block 30 at the front end of the take-up roller 26 to rotate, and the take-up roller 26 rotates synchronously. When the take-up roller 26 rotates, it drives the third transmission rod 35 to rotate along the inside of the third sleeve block 34. When it needs to be removed after winding is completed, the insert blocks 28 at both ends of the take-up roller 26 are pressed towards the position of the take-up roller 26, which drives the insert blocks 28 to retract and move along the outside of the guide rod 27. At the same time, when the insert blocks 28 move, they will squeeze the reset spring 29 to retract, and the insert blocks 28 will move outward along the inside of the fixed block 30 until the insert blocks 28 are completely separated from the inside of the fixed block 30, after which the take-up roller 26 can be removed.
