Description
Technical Field
[0001] This utility model relates to the field of parchment production and processing technology, and in particular to a parchment surface calendering and finishing device. Background Technology
[0002] Parchment is not made from actual sheepskin; it is a tough paper formed from plant fibers through a special process. It is durable, moisture-proof, and colorfast, and is commonly used in bookbinding, high-end packaging, and artistic creation. During parchment processing, a matte surface is often given to enhance its texture and aesthetics. Calendering devices precisely control the gloss of the parchment surface, preventing glare and giving the paper a soft, delicate visual and tactile feel. These devices are key to optimizing the appearance of parchment and expanding its applications.
[0003] Traditional calendering equipment typically has a fixed roller spacing, which cannot flexibly adapt to parchment of different thicknesses. When it is necessary to change the processing specifications, the equipment must be disassembled and adjusted. This process is not only cumbersome but also consumes a lot of time, seriously affecting production efficiency and processing flexibility, and making it difficult to meet diverse parchment processing needs. Utility Model Content

In addition, the width of the heating box slot is adapted to the width of the parchment paper, reducing heat loss. While ensuring the preheating effect, it reduces energy consumption, taking into account both processing quality and economy.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0019] Reference Figure 1 - Figure 4This utility model provides an embodiment of a parchment surface calendering and finishing device, comprising a base 1, a winding mechanism fixedly connected to one side of the base 1, an unwinding mechanism fixedly connected to the other side of the base 1, a second fixing plate 8 symmetrically fixedly connected to one side of the top of the base 1, a first fixing block 9 fixedly connected to the bottom of one side of the second fixing plate 8, a lower support roller 5 rotatably connected to one side of one of the first fixing blocks 9, a second motor 7 installed on one side of the other first fixing block 9, the output end of the second motor 7 being fixedly connected to one end of the lower support roller 5, a hydraulic rod 12 installed on the top of the second fixing plate 8, a second fixing block 10 fixedly connected to the output end of the hydraulic rod 12, an upper flexible roller 6 rotatably connected to one side of one of the second fixing blocks 10, a third motor 11 installed on one side of the other second fixing block 10, the output end of the third motor 11 being fixedly connected to one end of the upper flexible roller 6, and a heating mechanism fixedly connected to the other side of the top of the base 1.
[0020] Specifically, base 1 provides a stable support foundation for the entire device, supporting the winding mechanism, unwinding mechanism, calendering assembly, and heating mechanism; the winding mechanism is used to wind the calendered parchment into rolls, and the unwinding mechanism is used to unfold and convey the parchment rolls to be processed; the second fixing plate 8 provides an installation frame for the calendering assembly, the first fixing block 9 fixes the position of the lower support roller 5, and the second motor 7 drives the lower support roller 5 to rotate, providing power for the parchment conveying; the hydraulic rod 12 can drive the second fixing block 10 to move up and down, thereby adjusting the distance between the upper flexible roller 6 and the lower support roller 5 to adapt to parchment of different thicknesses, while controlling the calendering pressure; the third motor 11 drives the upper flexible roller 6 to rotate, cooperating with the lower support roller 5 to achieve stable conveying and crushing of the parchment; the heating mechanism is used to preheat the parchment before calendering, softening the paper fibers and improving the surface gloss and smoothness of the parchment after calendering.
[0021] Reference Figure 1 - Figure 3 The winding mechanism includes two first fixed plates 2. A fourth fixed block 22 is fixedly connected to one side of the first fixed plate 2. A winding roller 3 is rotatably connected to one side of one of the fourth fixed blocks 22. The bottom of the first fixed plate 2 is fixedly connected to the top of the base 1. A first motor 4 is installed on one side of the other fourth fixed block 22. The output end of the first motor 4 is fixedly connected to one end of the winding roller 3. The unwinding mechanism includes two third fixed plates 18. A third fixed block 21 is fixedly connected to one side of the third fixed plate 18. An unwinding roller 19 is rotatably connected to one side of one of the third fixed blocks 21. The bottom of the third fixed plate 18 is fixedly connected to the top of the base 1. A fourth motor 20 is installed on one side of the other third fixed block 21. The output end of the fourth motor 20 is fixedly connected to one end of the unwinding roller 19.
[0022] Specifically, in the winding mechanism, the first fixing plate 2 and the fourth fixing block 22 cooperate to fix both ends of the winding roller 3, ensuring stable rotation of the winding roller 3; the first motor 4 provides driving force to the winding roller 3, driving the winding roller 3 to rotate and evenly winding the calendered parchment. Its speed is adjustable and matches the parchment conveying speed to avoid paper pulling or loosening; in the unwinding mechanism, the third fixing plate 18 and the third fixing block 21 fix the position of the unwinding roller 19, and the fourth motor 20 drives the unwinding roller 19 to rotate, evenly unwinding the parchment to be processed and conveying it to the calendering assembly; the speed control of the unwinding roller 19 and the winding roller 3 is coordinated to ensure that the parchment is in a taut state throughout the processing, improving the calendering accuracy.
[0023] Reference Figure 1 - Figure 4 The heating mechanism includes a heating box 14. Temperature sensors 15 are symmetrically installed on one inner wall of the heating box 14. A through groove 17 is opened on one side of the heating box 14. Heating tubes 16 are symmetrically installed inside the heating box 14. A guide rail 13 is slidably connected to one side of the second fixing block 10. One side of the guide rail 13 is fixedly connected to the third fixing plate 18.
[0024] Specifically, in the heating mechanism, the heating box 14 provides a closed space for preheating. The symmetrically installed heating tubes 16 inside release heat after being powered on, uniformly heating the parchment paper passing through. The temperature sensor 15 monitors the temperature inside the heating box 14 in real time and feeds the data back to the control system. If the temperature is lower than the preset value, the power of the heating tubes 16 is increased; if the temperature is too high, the power is reduced to ensure stable preheating temperature. The through slot 17 allows the parchment paper to enter and exit the heating box 14. Its width is adapted to the width of the parchment paper to reduce heat loss. The guide rail 13 restricts the movement direction of the second fixed block 10 to ensure that the upper flexible roller 6 does not deviate when the hydraulic rod 12 drives it to move up and down, ensuring the parallelism between the upper flexible roller 6 and the lower support roller 5 and improving the uniformity of calendering.
[0025] Working principle: Before operation, the parchment roll to be processed is installed on the unwinding roller 19. The free end of the parchment is passed sequentially through the through slot 17 of the heating box 14, the gap between the upper flexible roller 6 and the lower support roller 5, and finally fixed on the take-up roller 3. After the equipment is started, the fourth motor 20 drives the unwinding roller 19 to rotate and release the parchment. The first motor 4 drives the take-up roller 3 to rotate synchronously to realize the continuous conveying of the parchment. At the same time, the heating tube 16 in the heating box 14 starts to work. The temperature sensor 15 monitors the temperature inside the box in real time and feeds it back to the control system to ensure that the heating temperature is stable within the set range. The parchment is uniformly preheated when passing through the heating box 14, which softens the paper fibers and facilitates subsequent calendering. The preheated parchment enters the upper flexible roller 6 and the lower support roller. Between points 5, the hydraulic rod 12 pushes the second fixed block 10 down along the guide rail 13, causing the upper flexible roller 6 to press against the parchment surface. The calendering force is controlled by adjusting the output pressure of the hydraulic rod 12. At the same time, the second motor 7 drives the lower support roller 5 to rotate, and the third motor 11 drives the upper flexible roller 6 to rotate in the opposite direction at the same linear speed. Under the combined action of pressure and friction, the parchment surface is calendered and finished, forming a smooth and flat surface. The calendered parchment continues to be wound up by the winding roller 3. Throughout the process, the unwinding, heating, calendering, and winding stages operate synchronously to ensure that the parchment is always kept taut and to avoid wrinkles or shifting. After all the parchment has been calendered and finished, all motors and heating tubes 16 are turned off, and the wound parchment roll is removed.
[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
