Description

Technical Field

[0001] This utility model relates to the field of drum paper production technology, specifically to drum paper production drying equipment. Background Technology

[0002] The phonograph is the core sound-producing component of a loudspeaker, consisting of a body, edges, and spacers (optional). Its material and structure directly affect sound quality. Based on material, it can be categorized into all-paper, composite, and Mylar types, with composite phonographs being the most common. The body is often made of paper-based materials (such as PP, aluminum, and copper), while the edges use elastic materials such as foam and rubber. In the production process of drum paper, drying is a crucial step. However, traditional drying methods involve directly drying the drum paper using a drying device. In practice, these devices can only dry one side of the drum paper, not both sides simultaneously. This uneven heating can easily lead to wrinkles, affecting the drying effect and product quality. Therefore, this invention proposes a drum paper production drying device that allows for simultaneous drying on both sides. Summary of the Invention

[0003] The purpose of this invention is to provide a drying equipment for paper drum production to solve the problems mentioned in the background art.

[0008] Preferably, each of the lower magnetic rings is equipped with an upper magnetic ring that is magnetically attracted to it.

[0009] Preferably, the outer surface of the upper magnetic ring is provided with a plurality of evenly distributed ventilation slots.

[0010] Preferably, each of the four corners of the lower surface of the lower heating plate is fixedly installed with a lower support leg, and each lower support leg is fixedly installed with an anti-slip pad at its bottom.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through its top-and-bottom hot air drying structure, can simultaneously dry both sides of the paper drum during the drying process. This provides the effect of simultaneous drying of both sides of the paper drum, improves the uniformity of heating on both sides, avoids wrinkles caused by drying only one side, and enhances the drying effect and production quality. At the same time, the dual-sided drying technology can also greatly increase the drying efficiency of the paper drum, eliminating the need for secondary flipping and drying, thus improving the overall drying speed and overall practicality. Furthermore, this utility model has several support slots set on the support center plate, so that multiple sets of drum paper can be dried simultaneously in a single double-sided drying time. It has the practical effect of drying multiple sets of drum paper simultaneously. Compared with traditional drying equipment, it does not need to dry the drum paper one by one. It has the practical effect of batch drying when in use, which greatly improves the drying efficiency of drum paper. Meanwhile, the hot air blown out from the top and bottom can pass through the equalization holes of the upper and lower equalization plates respectively. Through the structural design of the equalization plates, the uniformity of hot air output can be effectively improved, the uniform heating effect of the paper drum can be enhanced, and it has good practical use characteristics, thus improving the drying quality of the product.

Furthermore, fans 7 are fixedly installed on the upper surface of the upper heating plate 4 and the lower surface of the lower heating plate 5; In this structural design, the present invention has electric heating tubes 6 fixedly installed at both the upper and lower ends of the support center plate 1. The electric heating tubes 6 can perform heating treatment, while the fan 7 can ensure normal blowing effect. The two sets of fans 7 at the top and bottom can work with the electric heating tubes 6 to form hot air for drying, and blow it into the drum paper in the support groove 8 in two directions, so as to achieve the actual use effect of double-sided synchronous drying.

[0019] In this embodiment, in order to improve the uniformity of hot air output, an upper flow equalization plate 12 is fixedly installed between the middle of the four upper support columns 2, and a lower flow equalization plate 13 is fixedly installed between the middle of the four lower support columns 3. A plurality of linearly equally spaced flow equalization holes 14 are opened on the outer surfaces of the upper flow equalization plate 12 and the lower flow equalization plate 13. With this structural design, the hot air blown out in the upper and lower directions can pass through the equalization holes 14 of the upper equalization plate 12 and the lower equalization plate 13 respectively. By utilizing the structural design of the equalization plate, the uniformity of hot air output can be effectively improved, the uniform heating effect of the paper drum can be enhanced, and it has good practical use characteristics, thus improving the drying quality of the product.

[0020] In this embodiment, in order to magnetically clamp the paper drum in the support slot 8 and prevent it from being blown out during hot air drying, thereby improving drying stability, a method is provided as described in the appendix to the instruction manual. Figure 4 as well as Figure 5 As shown, a lower magnetic ring 9 is fixedly installed on the inner wall of each support groove 8, and each lower magnetic ring 9 is equipped with an upper magnetic ring 10 that is magnetically attracted to it. Several evenly distributed ventilation grooves 11 are opened on the outer surface of the upper magnetic ring 10.

[0021] With this structural design, when the support groove 8 supports the paper drum, the edge of the paper drum can be placed on the secondary platform of the support groove 8. At this time, the lower magnetic ring 9 is placed below the edge of the paper drum. Please refer to the instruction manual for details. Figure 5As shown, after the drum paper is placed, the upper magnetic ring 10 is placed on the edge of the drum paper. Through the mutual magnetic attraction between the lower magnetic ring 9 and the upper magnetic ring 10, the suspended edge of the drum paper can be clamped in the support groove 8. In actual use, it has a good magnetic clamping and fixing effect, preventing the drum paper from being blown out during hot air drying and improving the drying stability of the structure.

In actual use, it has a good magnetic clamping and fixing effect, preventing the drum paper from being blown out during hot air drying and improving the drying stability of the structure.

[0025] After all the paper drums are placed in the tray 8, the upper and lower fans 7 and heating tubes 6 are turned on. The heating tubes 6 provide heating, while the fans 7 ensure normal airflow. The two sets of fans 7 work together with the heating tubes 6 to generate hot air for drying, which is blown into the paper drums in the tray 8 from both the top and bottom, thus achieving the practical effect of simultaneous drying on both sides.

[0026] This utility model, through its top-and-bottom hot air drying structure, can simultaneously dry both sides of the paper drum during the drying process. This provides the effect of simultaneous drying of both sides of the paper drum, improves the uniformity of heating on both sides, avoids wrinkles caused by drying only one side, and enhances the drying effect and production quality. At the same time, the dual-sided drying technology can also greatly increase the drying efficiency of the paper drum, eliminating the need for secondary flipping and drying, thus improving the overall drying speed and overall practicality. Furthermore, this utility model has several support slots 8 on the support center plate 1, so that multiple sets of drum paper can be dried simultaneously in a single double-sided drying time. It has the practical effect of drying multiple sets of drum paper simultaneously. Compared with traditional drying equipment, it does not need to dry the drum paper one by one. It has the practical effect of batch drying when in use, which greatly improves the drying efficiency of drum paper. Meanwhile, the hot air blown out in the upper and lower directions can pass through the equalization holes 14 of the upper equalization plate 12 and the lower equalization plate 13 respectively.
