[0001] This solution belongs to the field of drying equipment technology, specifically involving a paper drying device for papermaking. Background Technology

[0002] Utility model patent CN220789244U discloses a paper dryer. This utility model includes a conveying and drying mechanism. An outer frame is fixedly connected to the outside of the conveying and drying mechanism. The outer frame has openings at the front and rear ends. Multiple fixing rings are fixedly connected to the top of the outer frame, passing through the top of the outer frame. A fan is fixedly connected to the top of the fixing rings, with a gap between the fan and the fixing rings. The conveying and drying mechanism includes two support frames, which are fixedly connected to the left and right inner walls of the outer frame, respectively. Support rollers are rotatably connected between the front and rear top ends of the two support frames. A conveyor belt is slidably sleeved between the outer walls of the two support rollers, and the outer wall of the conveyor belt has drying holes. This utility model uses a conveyor belt with drying holes, utilizes heating pipes to generate heat, and strengthens airflow through a fan to expel the steam generated during paper drying, resulting in more uniform drying, reducing the impact of steam on the drying effect, and improving drying efficiency.

[0003] However, the device has some shortcomings. When in use, it is not convenient to limit the paper, which causes the paper to move when blown by the wind, making the paper easy to break. At the same time, after the paper dries, it will stick to the conveyor belt, making it inconvenient to detach the paper. Utility Model Content

[0004] The purpose of this solution is to provide a paper drying device for papermaking, in order to solve the problems that the device is not convenient to limit the paper during use, which causes the paper to move due to wind and become easily damaged. At the same time, the paper will stick to the conveyor belt after drying, making it difficult to detach the paper.

[0005] To achieve the above objectives, this solution provides a paper drying device for papermaking, including a drying chamber. A support frame is fixedly installed inside the drying chamber, and a support roller is rotatably connected inside the support frame. A motor is fixedly installed at the front end of the support frame, and a conveyor belt is provided on the outside of the support roller. A cleaning mechanism is provided on the drying chamber, and a cylinder is fixedly installed in the middle of the upper end of the drying chamber. The cylinder rod of the cylinder passes through the drying chamber and is slidably connected to the drying chamber, and a drying mechanism is provided on the cylinder rod.

[0006] The principle of this solution is as follows: During use, the paper is placed on the conveyor belt, the motor is started, and the motor drives the support roller to rotate. The support roller drives the conveyor belt to rotate and transport the paper. Then, the cylinder is activated, and the cylinder rod extends, causing the cylinder rod to move the spring downward. This causes the spring to press the connecting pipe, which in turn moves the fan hood, which in turn moves the suspension rod, which in turn moves the pressure roller. The extension of the cylinder rod by the cylinder causes the spring to elastically press down on the connecting pipe, which in turn causes the fan hood to elastically press down on the pressure roller. This ensures that the paper remains in contact with the conveyor belt during the drying process, preventing lateral movement of the paper and avoiding scratches and damage. When the paper moves to contact the doctor blade, the sliding sleeve rotates, causing the connecting rod to deflect the sliding shaft, which in turn moves the doctor blade. This allows the doctor blade to scrape against the conveyor belt, making it easier to separate the dried paper from the conveyor belt.

[0007] The technical effect of this solution is that by rotating the sliding sleeve, the connecting rod drives the sliding shaft to deflect, which in turn drives the doctor blade to move, allowing the doctor blade to scrape against the conveyor belt, making it easier to separate the dried paper from the conveyor belt.

[0008] The cylinder rod is extended by the cylinder, which in turn causes the spring to press down on the connecting pipe, which in turn causes the air hood to press down on the pressure roller. This ensures that the paper remains in contact with the conveyor belt during the drying process, preventing lateral movement of the paper and avoiding scratches and damage.

[0009] Furthermore, the motor's shaft passes through the bracket and is rotatably connected to the bracket, while the motor's shaft is fixedly connected to the support roller. By installing the motor, the support roller is driven to rotate.

[0010] Furthermore, the cleaning mechanism includes a support shaft, which is fixedly connected to the front end of the drying chamber. A sliding sleeve is rotatably connected to the outer side of the support shaft. A pressure ring is threadedly connected to the outer side of the support shaft, and the pressure ring contacts the sliding sleeve. A connecting rod is fixedly connected to the surface of the sliding sleeve. A sliding shaft is fixedly connected to the end of the connecting rod, and a scraper is fixedly connected to the end of the sliding shaft. The scraper contacts the conveyor belt. By rotating the sliding sleeve, the connecting rod drives the sliding shaft to deflect, which in turn causes the sliding shaft to move the scraper. This allows the scraper to scrape against the conveyor belt, facilitating the separation of the dried paper from the conveyor belt.

[0011] Furthermore, the drying oven has a sliding groove inside, which is slidably connected to a sliding shaft. The sliding groove guides the movement of the sliding shaft.

[0012] Furthermore, the drying mechanism includes a sliding cylinder, which is slidably connected to the outside of the cylinder rod of the cylinder. A connecting pipe is fixedly connected to the lower end of the sliding cylinder. A spring is installed inside the sliding cylinder. A hot air pump is fixedly installed at the upper end of the drying chamber. The air inlet pipe of the hot air pump passes through the drying chamber and is slidably connected to it. The air inlet pipe of the hot air pump is fixedly connected to the connecting pipe. A fan hood is fixedly connected to the lower end of the connecting pipe. A suspension rod is fixedly connected to the lower end of the fan hood. A pressure roller is installed at the lower end of the suspension rod. By driving the cylinder rod to extend, the spring elastically presses down on the connecting pipe, which in turn causes the fan hood to elastically press down on the pressure roller. This ensures that the paper remains in contact with the conveyor belt during the drying process, preventing lateral movement of the paper and avoiding scratches and damage.

[0013] Furthermore, a sliding pin is fixedly connected to the surface of the cylinder rod, and the sliding pin is slidably connected to the slide cylinder. The stroke of the slide cylinder is limited by the sliding pin.

[0014] Furthermore, one end of the spring is fixedly connected to the cylinder rod of the cylinder, and the other end of the spring is fixedly connected to the connecting pipe. By setting the spring, the connecting pipe is elastically compressed downwards. Attached Figure Description

[0021] The implementation examples are basically as follows Figure 1 , Figure 2 As shown, this embodiment provides a paper drying device for papermaking, including a drying box 1. A bracket 2 is fixedly installed inside the drying box 1. A support roller 3 is rotatably connected inside the bracket 2. A motor 4 is fixedly installed at the front end of the bracket 2. The rotating shaft of the motor 4 passes through the bracket 2 and is rotatably connected to the bracket 2. The rotating shaft of the motor 4 is fixedly connected to the support roller 3. By setting the motor 4, the support roller 3 is driven to rotate. A conveyor belt 5 is set on the outside of the support roller 3. A cleaning mechanism 6 is set on the drying box 1. A cylinder 7 is fixedly installed in the middle of the upper end of the drying box 1. The cylinder rod of the cylinder 7 passes through the drying box 1 and is slidably connected to the drying box 1. A drying mechanism 8 is set on the cylinder rod of the cylinder 7.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, the cleaning mechanism 6 includes a support shaft 61. The front end of the drying chamber 1 is fixedly connected to the support shaft 61. A sliding sleeve 62 is rotatably connected to the outside of the support shaft 61. A pressure ring 63 is threadedly connected to the outside of the support shaft 61. The pressure ring 63 and the sliding sleeve 62 are in contact. A connecting rod 64 is fixedly connected to the surface of the sliding sleeve 62. A sliding shaft 65 is fixedly connected to the end of the connecting rod 64. A sliding groove 66 is provided inside the drying chamber 1. The sliding groove 66 and the sliding shaft 65 are slidably connected. The sliding groove 66 guides the movement of the sliding shaft 65. A scraper 67 is fixedly connected to the end of the sliding shaft 65. The scraper 67 is in contact with the conveyor belt 5. By rotating the sliding sleeve 62, the connecting rod 64 drives the sliding shaft 65 to deflect, which in turn causes the sliding shaft 65 to drive the scraper 67 to move. This allows the scraper 67 to scrape against the conveyor belt 5, making it easier to separate the dried paper from the conveyor belt 5.

[0023] like Figure 2 , Figure 4As shown, the drying mechanism 8 includes a slide cylinder 81. The slide cylinder 81 is slidably connected to the outer side of the cylinder rod of the cylinder 7. A sliding pin 82 is fixedly connected to the surface of the cylinder rod of the cylinder 7. The sliding pin 82 and the slide cylinder 81 are slidably connected. By setting the sliding pin 82, the stroke of the slide cylinder 81 is limited. A connecting pipe 83 is fixedly connected to the lower end of the slide cylinder 81. A spring 84 is set inside the slide cylinder 81. One end of the spring 84 is fixedly connected to the cylinder rod of the cylinder 7, and the other end of the spring 84 is fixedly connected to the connecting pipe 83. By setting the spring 84, the connecting pipe 83 is elastically compressed downwards. A hot air supply is fixedly installed at the upper end of the drying chamber 1. Pump 85, the air inlet pipe of hot air pump 85 passes through drying chamber 1 and is slidably connected to drying chamber 1. The air inlet pipe of hot air pump 85 is fixedly connected to connecting pipe 83. The lower end of connecting pipe 83 is fixedly connected to air hood 86. The lower end of air hood 86 is fixedly connected to hanging rod 87. The lower end of hanging rod 87 is equipped with pressure roller 88. The cylinder rod is driven by cylinder 7 to extend, thereby causing spring 84 to elastically press down connecting pipe 83, thereby causing air hood 86 to elastically press down pressure roller 88, thereby ensuring that the paper always keeps in contact with conveyor belt 5 during the drying process, avoiding lateral movement of the paper during the drying process, which would cause the paper to scratch and break.

[0024] The specific implementation process of this utility model is as follows: In use, the paper is placed on the conveyor belt 5, the motor 4 is started, the motor 4 drives the support roller 3 to rotate, the support roller 3 drives the conveyor belt 5 to rotate and transport the paper, then the cylinder 7 is started, the cylinder 7 drives the cylinder rod to extend, the cylinder rod drives the spring 84 to move downward, so that the spring 84 moves downward and squeezes the connecting pipe 83, the connecting pipe 83 drives the wind cover 86 to move, the wind cover 86 drives the hanging rod 87 to move, the hanging rod 87 drives the pressure roller 88 to move, and the cylinder 7 drives the cylinder rod to extend, thereby causing the spring 84 to move downward and squeeze the connecting pipe 83, the connecting pipe 83 drives the wind cover 86 to move, the wind cover 86 drives the hanging rod 87 to move, the hanging rod 87 drives the pressure roller 88 to move, and the cylinder 7 drives the cylinder rod to extend, thus causing the spring 84 to move downward and squeeze the connecting pipe 83 to move. 4. The elastic downward pressure connecting pipe 83 causes the air hood 86 to elastically press down the pressure roller 88, thus ensuring that the paper remains in contact with the conveyor belt 5 during the drying process, preventing lateral movement of the paper during drying and avoiding scratching and damage. When the paper moves to contact the doctor blade 67, the sliding sleeve 62 rotates, causing the connecting rod 64 to drive the sliding shaft 65 to deflect, which in turn causes the sliding shaft 65 to drive the doctor blade 67 to move, allowing the doctor blade 67 to scratch the conveyor belt 5, making it easier to separate the paper from the conveyor belt 5 after drying.

[0025] The rotation of the sliding sleeve 62 causes the connecting rod 64 to drive the sliding shaft 65 to deflect, which in turn causes the sliding shaft 65 to drive the doctor blade 67 to move, allowing the doctor blade 67 to scrape against the conveyor belt 5, making it easier to separate the dried paper from the conveyor belt 5.

[0026] The cylinder rod is extended by the cylinder 7, which causes the spring 84 to press down on the connecting pipe 83, which in turn causes the fan shroud 86 to press down on the pressure roller 88. This ensures that the paper remains in contact with the conveyor belt 5 during the drying process, preventing lateral movement of the paper and avoiding scratches and damage.
