Description

Technical Field

[0001] This utility model relates to the field of paper drying technology, specifically a paper drying deformation correction device. Background Technology

[0002] In the loudspeaker manufacturing process, the drum paper, as the core sound-generating component, plays an important role in the sound quality of the loudspeaker. The paper material commonly used for drum paper has a certain degree of hygroscopicity. During the drying process, the rapid loss of moisture will cause the paper fibers to shrink. Since the shrinkage rate of the fibers is inconsistent in different directions, the drum paper is prone to deformation.

[0003] Traditional paper drying processes often use fixed air outlets for hot air delivery, making it difficult to evenly cover the paper surface with hot air. This results in localized overheating or underheating, leading to uneven stress distribution and deformation within the paper. Furthermore, minor deformations are typically corrected manually using tools such as pressure plates, which is inefficient, highly susceptible to subjective factors, and physically demanding, leading to fatigue and poor product quality stability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a device for correcting deformation during the drying of paper drums, which solves the problem of deformation that easily occurs during the traditional paper drum drying process.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1-5 This utility model provides a technical solution: a paper drying deformation correction device, including a housing 1 and a paper positioning cone 2. The bottom of the paper positioning cone 2 is fixedly connected to the bottom of the inner cavity of the housing 1 via a connecting block. A drive motor 3 is fixedly connected to the top of the inner cavity of the housing 1. The drive motor 3 is powered by an external power source. A rotating rod 4 is fixedly connected to the output end of the drive motor 3 via a coupling. A first rotating gear 5 is fixedly connected to the bottom end of the rotating rod 4. An annular groove 6 is provided on the top of the inner cavity of the housing 1. Sliding blocks 7 are slidably connected to both sides inside the annular groove 6. The bottoms of the two sliding blocks 7 are fixed together by connecting rods. A hot air transmission pipe 8 is connected, and an air supply pipe 9 is connected to the top of the hot air transmission pipe 8. A second rotating gear 10 that meshes with the first rotating gear 5 is fixedly sleeved on the outer periphery of the air supply pipe 9. An internal threaded cylinder 11 is fixedly connected to the bottom of the hot air transmission pipe 8. A threaded rod 12 is connected to the internal thread of the internal threaded cylinder 11. A paper-pressing cone 13 that cooperates with the paper-pressing cone 2 is fixedly connected to the bottom of the threaded rod 12. Slide rods 14 are fixedly connected to both sides of the bottom of the inner cavity of the box 1. Slide sleeves 15 are sleeved and slidably connected to the outer periphery of the slide rods 14. The opposite sides of the two slide sleeves 15 are fixedly connected to both sides of the paper-pressing cone 13 through connecting blocks.

[0020] Furthermore, to avoid uneven drying of the paper drum, a hot air blower 16 is installed on the top of the housing 1. The hot air blower 16 is powered by an external power source. The air outlet of the hot air blower 16 is connected to an air supply pipe 17. One end of the air supply pipe 17 passes through the housing 1 and extends into the inner cavity of the housing 1. The top end of the air supply pipe 9 is connected to a sealing docking plate 18 through a rotary joint. The end of the air supply pipe 17 extending into the inner cavity of the housing 1 is connected to the top of the sealing docking plate 18. Both sides of the bottom of the hot air transmission pipe 8 are connected to air guide pipes 19. In order to facilitate the up and down movement of the air outlet pipe 20, the air guide pipe 19 is reserved with redundant length. The bottom end of the air guide pipe 19 is connected to the air outlet pipe 20.

[0021] Furthermore, in order to improve the uniformity and efficiency of heating the drying of the paper surface, telescopic cylinders 21 are fixedly connected to both sides of the bottom of the hot air transmission pipe 8 and between the two air guide pipes 19. Telescopic rods 22 are slidably connected inside the telescopic cylinders 21, and the bottom end of the telescopic rods 22 is fixedly connected to the top of the air outlet pipe 20.

[0022] In order for the paper-pressing cone 13 to move downward and adhere to the paper during the process, the air outlet 20 can continuously dry the paper. Inside the telescopic cylinder 21 and above the telescopic rod 22, a pressing block 23 is slidably connected. A spring 24 is fixedly connected between the pressing block 23 and the telescopic rod 22. A crossbar 25 is fixedly connected to one side of the pressing block 23. A U-shaped plate 26 is fixedly connected to the opposite end of the two crossbars 25. A vertical groove that cooperates with the crossbar 25 is opened on the opposite side of the two telescopic cylinders 21. L-shaped rods 27 are fixedly connected to both sides of the threaded rod 12. An annular plate 28 that cooperates with the U-shaped plate 26 is fixedly connected to the ends of the two L-shaped rods 27.

[0023] A vertical rod 29 is fixedly connected to the bottom of the air outlet duct 20, and a ball bearing is provided at the bottom end of the vertical rod 29.

[0024] During operation, the paper to be dried is placed on the paper positioning cone 2, the hot air blower 16 is turned on, and hot air is delivered to the air outlet pipe 20 through the air supply pipe 17, air conveying pipe 9, hot air transmission pipe 8 and air guide pipe 19. The drive motor 3 is started, and the drive motor 3 drives the first rotating gear 5 to rotate through the rotating rod 4. The first rotating gear 5 drives the second rotating gear 10 meshing with it to rotate. The second rotating gear 10 drives the air conveying pipe 9 to rotate. The rotation of the air conveying pipe 9 drives the hot air transmission pipe 8 connected to it to rotate. The hot air transmission pipe 8 drives the air outlet pipe 20 to rotate through the telescopic cylinder 21 and telescopic rod 22. The rotating air outlet pipe 20 blows hot air to dry the surface of the paper.

[0025] Simultaneously, the rotation of the hot air transmission pipe 8 drives the internal threaded cylinder 11 to rotate, causing the threaded rod 12 to move the paper drum pressing cone 13 downward. When the paper drum pressing cone 13 moves downward, the threaded rod 12 drives the U-shaped plate 26 downward through the L-rod 27 and the annular plate 28. The U-shaped plate 26 drives the air outlet pipe 20 downward synchronously through the crossbar 25, the extrusion block 23, the spring 24, and the telescopic rod 22. This allows the air outlet pipe 20 to move synchronously with the paper drum pressing cone 13 while rotating, improving the efficiency and uniformity of paper drying. When the air outlet pipe 20 moves downward to the designated position, the vertical rod 29 touches the bottom of the inner cavity of the box 1. The air outlet pipe 20 continues to dry the paper drum. At this time, the paper drum pressing cone 13 continues to move downward. The annular plate 28 extrudes the spring 24 through the extrusion block 23. The paper drum pressing cone 13 moves downward until it fits the paper drum, thus deforming and correcting the paper drum placed on the paper drum positioning cone 2.

[0026] After the paper drum pressing cone 13 and the paper drum are bonded together by the threaded rod 12 and the internal threaded cylinder 11, the reverse drive motor 3 drives the rotating rod 4 to reverse, causing the paper drum pressing cone 13 to move upward. During the upward movement of the paper drum pressing cone 13, the air outlet pipe 20 will move upward, thereby drying the paper drum again. After the paper drum pressing cone 13 moves upward to the initial position and the paper drum is pressed and deformed and corrected, the drive motor 3 and the hot air blower 16 are turned off, and the paper drum is removed.
