Description

Technical Field

[0001] This utility model relates to the field of parchment processing, and in particular to a leveling device for parchment processing. Background Technology

[0002] Parchment is typically made from plant fibers through a special process. It has good toughness, tear resistance, and water resistance, and its smooth surface makes it easy to write on, print on, or undergo further processing. It has a wide range of uses, including making archival documents, book covers, and packaging materials. It plays an important role in cultural preservation and the packaging industry.

[0003] In the actual parchment processing flow, the existing leveling equipment is not well adapted to the parchment. Due to the lack of a guiding and adjusting structure, when the parchment enters the leveling stage, it is easily affected by factors such as its own dimensional deviation and conveying tension fluctuations, resulting in problems such as difficulty in edge alignment and conveying path deviation. Frequent manual intervention and adjustment are required, which will cause the leveling operation to be unable to be carried out continuously and stably. This not only prolongs the leveling time of a single batch of parchment, but also reduces the overall operating efficiency of the production line. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a leveling device for parchment processing, which aims to solve the problem that "the existing technology lacks a guiding and adjusting structure, which leads to prolonged leveling time and reduced work efficiency".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a parchment paper leveling device, comprising a base, with second vertical blocks fixedly connected to the left and right sides of the upper surface of the base, a second support block fixedly connected to the upper surface of the base, a second motor installed on the upper surface of the second support block, and a guide component provided on the inner wall of the second vertical block; The guiding component includes a second sliding block, which is slidably connected to the inner wall of the second vertical block. A second limiting rod is slidably connected to the inner wall of the second sliding block. A second rack is fixedly connected to the front end of the second sliding block.

The second limiting rod is fixedly connected to the inner wall of the second vertical block. The pressing roller is rotatably connected to the inner wall of the second sliding block. The first sliding block is slidably connected to the inner wall of the second vertical block. The first limiting rod is fixedly connected to the inner wall of the second vertical block. The heating roller is rotatably connected to the inner wall of the first sliding block. The second motor output shaft passes through and is rotatably connected to the inner wall of the second vertical block.

[0007] As a further description of the above technical solution: The upper surface of the base is equipped with an unwinding mechanism and a rewinding mechanism from front to back.

[0008] As a further description of the above technical solution: The upper surface of the base is fixedly connected to the left and right sides of the first vertical block, and the inner wall of the first vertical block is rotatably connected to the guide rod.

[0009] As a further description of the above technical solution: A first support block is fixedly connected to the upper surface of the base, and a first motor is mounted on the upper surface of the first support block.

[0012] As a further description of the above technical solution: The outer wall of the guide rod is configured with a double-threaded wire structure.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the guide component set on the inner wall of the second vertical block can start the second motor when the parchment is to be guided. The output shaft of the second motor drives the gear to rotate, so that the meshing second rack and the first rack move towards the center, thereby driving the extrusion roller and the heating roller to be adjusted in parallel.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Reference Figure 1 - Figure 2This utility model provides an embodiment of a parchment paper leveling device, comprising a base 1, which serves as the base of the entire device and bears the weight of all functional components. Second vertical blocks 8 are fixedly connected to both the left and right sides of the upper surface of the base 1. The second vertical blocks 8 serve as the mounting carrier for the guide assembly 2 and also as the sliding track for the heating roller 9 and the pressing roller 10. A second support block 11 is fixedly connected to the upper surface of the base 1, providing stable support for a second motor 12. The second motor 12 is mounted on the upper surface of the second support block 11. The power is converted into horizontal moving force of the first sliding block 23 and the second sliding block 27, thereby driving the heating roller 9 and the extrusion roller 10 to move closer to or away from the center of the second vertical block 8. The inner wall of the second vertical block 8 is provided with a guide component 2, which is used to facilitate the guidance of the parchment and reduce the difficulty of manual guidance. The guide component 2 includes a second sliding block 27, which is used to drive the roller to adjust the contact position and pressure with the parchment. The second sliding block 27 is slidably connected to the inner wall of the second vertical block 8, and the inner wall of the second sliding block 27 is slidably connected with a second limit. Rod 26, the second limiting rod 26, is used to limit the sliding trajectory of the second sliding block 27 to prevent deviation. The front end of the second sliding block 27 is fixedly connected to a second rack 25. The second rack 25 is used to drive the sliding block to move synchronously through its own linear movement, thereby adjusting the position of the heating roller 9 and the extrusion roller 10. The inner wall of the second vertical block 8 is slidably connected to a first sliding block 23. The first sliding block 23 is used to drive the heating roller 9 to adjust the contact position and pressure with the parchment paper. The rear end of the first sliding block 23 is connected to a first rack 22. The first rack 22 is used to drive the sliding block to move synchronously through its own linear movement. The movement drives the sliding block to move synchronously, thereby adjusting the position of the heating roller 9 and the extrusion roller 10. The inner wall of the first sliding block 23 is slidably connected to the first limiting rod 24, which is used to limit the sliding trajectory of the first sliding block 23 and prevent deviation. The right end of the output shaft of the second motor 12 is provided with a gear 21, which is used to convert the rotational power of the second motor 12 into the linear motion power of the first rack 22 and the second rack 25. The gear 21 is meshed with the second rack 25 and the first rack 22 from front to back, respectively, at the end near the center of the second vertical block 8.

[0018] Reference Figure 3 - Figure 4The inner wall of the second vertical block 8 is slidably connected from front to back to a heating roller 9 and a pressing roller 10. The heating roller 9 is used to continuously heat the lower surface of the parchment during the conveying process, softening the parchment fibers and creating conditions for subsequent extrusion and shaping. The pressing roller 10 is used to flatten the wrinkles and warps on the surface of the parchment by utilizing the softening effect of the heating roller 9, achieving a flattening effect. The second limiting rod 26 is fixedly connected to the inner wall of the second vertical block 8, and the pressing roller 10 is rotatably connected to the second sliding block. The inner wall of the base 1 is slidably connected to the inner wall of the second vertical block 8 by the first sliding block 23, the first limiting rod 24 is fixedly connected to the inner wall of the second vertical block 8, the heating roller 9 is rotatably connected to the inner wall of the first sliding block 23, and the output shaft of the second motor 12 passes through and is rotatably connected to the inner wall of the second vertical block 8. The upper surface of the base 1 is equipped with an unwinding mechanism 3 and a winding mechanism 17 from front to back. The unwinding mechanism 3 is used to convey the parchment to be flattened, and the winding mechanism 17 is used to roll up the flattened parchment.

[0019] Reference Figure 5 The upper surface of the base 1 is fixedly connected to the left and right sides of the first vertical block 4, which serves as the mounting bracket for the guide rod 5. The guide rod 5 is rotatably connected to the inner wall of the first vertical block 4. The guide rod 5 is used to guide the parchment paper to move along the correct path by rotating itself. On the other hand, when the parchment paper wrinkles, the bidirectional thread can generate a tensile force towards the edge on both sides of the parchment paper, simultaneously unfolding the wrinkles and reducing processing losses. The upper surface of the base 1 is fixedly connected to the first support block 6, which provides stable support for the first motor 7. The first motor 7 is mounted on the upper surface of the first support block 6. The first motor 7 is used to drive the guide rod 5 to rotate through the output shaft. When the parchment paper has local wrinkles, its power can be converted into the torque of the guide rod 5. Utilizing the bidirectional thread structure of the guide rod 5, the wrinkles are simultaneously unfolded to both sides, eliminating processing defects. The first motor 7... The output shaft is fixedly connected to the left end of the guide rod 5. The upper surface of the base 1 is fixedly connected to the left and right sides of the third vertical block 1. The third vertical block 18 provides a mounting bracket for the air knife 13 and the support rod 14. The inner wall of the third vertical block 18 is rotatably connected to the support rod 14. The support rod 14 is used to provide stable support for the leveled parchment and ensure that the parchment maintains a flat conveying posture. The inner wall of the third vertical block 18 is penetrated and the air knife 13 is installed. The air knife 13 is used to blow a uniform airflow through the strip-shaped air outlet to reduce the temperature of the parchment. The upper surface of the base 1 is equipped with a high-pressure pump 16. The upper end of the high-pressure pump 16 is provided with an air supply pipe 15. The air supply pipe 15 is an airflow delivery channel used to stably deliver the high-pressure airflow generated by the high-pressure pump 16 to the air knife 13. The right end of the air supply pipe 15 is fixedly connected to the left end of the air knife 13. The outer wall of the guide rod 5 is set with a double-headed thread structure.

[0020] Working principle: After the device is started, the unwinding mechanism 3 on the upper surface of the base 1 is activated first to release the parchment material to be leveled, and the parchment is oriented and conveyed to the direction of the second vertical block 8. During this process, the guide rod 5 on the inner wall of the first vertical block 4 first guides the parchment to prevent the material from shifting significantly in the initial stage of conveying. When the parchment is about to enter the heating and leveling stage, the second motor 12 installed on the second support block 11 is started. The output shaft of the second motor 12 drives the gear 21 to rotate. Since the gear 21 meshes with the second rack 25 on the front side and the first rack 22 on the rear side at the same time, it can synchronously drive the two sets of racks to move in opposite or the same direction. The second rack 25 drives the second sliding block 27 fixed to it to slide horizontally along the second limiting rod 26 on the inner wall of the second vertical block 8. At the same time, the first rack 22 drives the first sliding block 23 to slide synchronously along the first limiting rod 24. Because the extrusion roller 10 is rotatably connected to the inner wall of the second sliding block 27, the heating roller... The cylinder 9 is rotatably connected to the inner wall of the first sliding block 23. When the two sets of sliding blocks move, they will drive the extrusion roller 10 and the heating roller 9 to move synchronously closer to the center of the second vertical block 8 until they are matched with the height of the parchment currently being conveyed, thus completing the guidance before leveling. After the guidance is completed, the second motor 12 maintains a stable output, so that the gear 21 maintains a fixed speed. The rack drives the sliding block to maintain pressure, the extrusion roller 10 applies uniform pressure from above the parchment, and the heating roller 9 provides continuous heat from below. Under the action of "heating and softening - extrusion and shaping", the uneven parts such as wrinkles and warping on the surface of the parchment are gradually smoothed out, achieving the leveling effect.

[0021] The leveled parchment continues to be conveyed backward into the third vertical block 18 area. The high-pressure pump 16 on the base 1 is activated, and the high-pressure pump 16 delivers compressed air through the air pipe 15 to the air knife 13 installed on the inner wall of the third vertical block 18. The air knife 13 blows a uniform airflow onto the upper surface of the parchment through the strip-shaped air outlet, quickly reducing the temperature of the parchment and preventing it from undergoing secondary deformation due to residual heat, thus completing the shaping process. The support rod 14, which is rotatably connected to the inner wall of the third vertical block 18, contacts the lower surface of the parchment, providing stable support without damaging the paper surface, ensuring that the parchment maintains a flat conveying posture during the cooling process. Finally, the winding mechanism 17 on the rear side of the base 1 is activated, and its rotation speed is synchronized with the conveying speed of the unwinding mechanism 3 and the leveling mechanism, uniformly winding the cooled and shaped flat parchment into a roll, completing the leveling process of a single batch of parchment.

[0022] When local wrinkles appear on the parchment during the conveying process, the first motor 7 on the first support block 6 is started. The output shaft of the first motor 7 drives the guide rod 5 to rotate. Since the outer wall of the guide rod 5 adopts a double-headed thread structure, it will generate a tensile force on both sides of the parchment towards the edge when rotating, which will simultaneously unfold the wrinkled parts to both sides, eliminate local wrinkles, prevent wrinkles from entering the subsequent leveling process and causing processing defects, and ensure the stability of product quality.

[0023] 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.
