Description

Technical Field

[0001] This utility model relates to the field of parchment softening technology, specifically a brushing device for parchment softening. Background Technology

[0002] Parchment, as an important medium carrying thousands of years of human civilization and wisdom, continues to exude timeless charm in the fields of high-end art, document restoration, and luxury cultural and creative products due to its unique texture and durability. In these fields, the softness and tactile feel of the surface are not only core indicators of its quality but also key factors determining its artistic value and user experience. Traditional parchment brushing, as a finishing process that gives it a delicate feel, has long relied on the manual skills of artisans or semi-automated mechanical processing, which has limited its effectiveness and efficiency.

[0003] Traditional brushing devices mostly use a solid roller structure with bristles fixed on its surface. They physically brush the parchment paper while it is moving by rotating at high speed. The bristles of conventional brushing rollers are too rigid and cannot effectively adapt to the natural slight undulations and tension fluctuations of parchment paper. This results in uneven brushing pressure. Some areas may be damaged by excessive brushing, while other areas may be affected by insufficient brushing, resulting in poor softness uniformity of the entire parchment paper. In addition, the fine dander, dust and broken fiber fluff generated during the brushing process in the existing technology will diffuse in the working area, not only polluting the workshop environment, but also easily re-adhere to the treated paper surface under the action of airflow, causing secondary pollution and seriously affecting the cleanliness and quality of the product.

[0016] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] This embodiment proposes a brushing device for treating the softness of parchment. Figures 1-7 As shown, the machine includes a frame 1 and parchment 2. An adjusting frame 7 is mounted on the frame 1. The parchment 2 is slidably connected to the frame 1. Two sets of symmetrically distributed mounting frames 3 are slidably mounted below the frame 1. A rotating seat 4 is rotatably mounted on each of the two sets of mounting frames 3, and a take-up roller 5 is engaged between the two sets of rotating seats 4. The parchment 2 is wound onto the take-up roller 5. A rotating roller 10 is rotatably mounted on the adjusting frame 7. Multiple sets of annularly distributed support columns 11 are fixedly mounted on the rotating roller 10. A first sliding rod 12 is fixedly mounted inside each support column 11, and a support rod 14 is slidably mounted inside each support column 11. A brush head 15 is fixedly mounted on the end of the support rod 14 away from the rotating roller 10, and the brush head 15 is in contact with the surface of the parchment 2. The rod 14 is slidably sleeved with the first slide rod 12. Two sets of symmetrically distributed first springs 13 are fitted on the first slide rod 12. The two ends of the two sets of first springs 13 are fixedly connected to the support rod 14 and the support column 11, respectively. During operation, the winding roller 5 drives the parchment paper 2 to move at a constant speed. At the same time, the rotating roller 10 drives the brush heads 15 distributed in a ring on its surface to rotate at high speed. The brush heads 15 form an elastic expansion and contraction structure through the sliding cooperation between the support rod 14 and the first slide rod 12 and the buffering effect of the two sets of first springs 13. This allows them to adapt to the natural undulations and tension fluctuations on the surface of the parchment paper 2, realize dynamic pressure adjustment, and ensure that the entire parchment paper 2 obtains a uniform and consistent soft treatment effect.

[0018] In this embodiment, reference Figures 1-5As shown, a cylinder 8 is fixedly installed on the frame 1. An adjusting frame 7 is slidably connected to the frame 1 via a slide rail, and the adjusting frame 7 is fixedly connected to the output end of the piston rod of the cylinder 8. A bidirectional lead screw 6 is rotatably installed on the frame 1. The two ends of the bidirectional lead screw 6 pass through two sets of mounting frames 3 respectively and are threadedly connected to the two sets of mounting frames 3 respectively. The adjusting frame 7 and the mounting frames 3 are located on both sides of the parchment 2. The cylinder 8 pushes the adjusting frame 7 to move up and down precisely along the slide rail through the piston rod, thereby adjusting the working distance between the rotating roller 10 and the parchment 2. The rotation of the bidirectional lead screw 6 drives the two sets of mounting frames 3 to move synchronously in opposite directions, thereby realizing the axial position adjustment of the winding roller 5 and ensuring that the parchment 2 always maintains a suitable tension and centering position during the brushing process.

[0019] In this embodiment, reference Figure 6 , Figure 7 As shown, the adjusting frame 7 is equipped with a dust removal mechanism 9 for cleaning the brush head 15, avoiding secondary pollution to the work area and parchment 2. The dust removal mechanism 9 includes a dust collection box 901 fixedly installed on the adjusting frame 7, a negative pressure fan 902 fixedly embedded in the dust collection box 901, a partition 904 fixedly installed inside the dust collection box 901, and multiple sets of equidistantly distributed filter cartridges 905 fixedly installed on the partition 904. A dust suction port 903 is fixedly installed on the adjusting frame 7, and the dust suction port 903 is open to... The hose is connected to the dust collection box 901, and the partition 904 is located between the negative pressure fan 902 and the connection port between the hose and the dust collection box 901. After the negative pressure fan 902 is started, a negative pressure environment is formed in the dust collection box 901. The dust and impurities generated during the brushing process are sucked into the box through the dust suction port 903 and the hose. When the dust-laden airflow passes through the multi-layer filter cartridge 905 at the partition 904, the dust particles are effectively intercepted. The purified air is discharged by the negative pressure fan 902, realizing continuous dust removal operation.

[0020] A mounting frame 906 is fixedly installed on the suction port 903. The mounting frame 906 is correspondingly set with the brush head 15, and a dusting plate 907 is slidably installed inside the mounting frame 906. A sealing rubber 916 is connected at the interface between the dusting plate 907 and the mounting frame 906. The bottom of the dusting plate 907 is in contact with the brush head 15. A second sliding rod 908 is fixedly installed inside the mounting frame 906. The dusting plate 907 and the second sliding rod 908 are slidably sleeved together, and two sets of symmetrically distributed second springs 909 are fitted on the second sliding rod 908. The two ends of the spring 909 are fixedly connected to the duster plate 907 and the mounting frame 906, respectively. The cam 910 is rotatably installed in the mounting frame 906 and is fitted with the duster plate 907. When the cam 910 rotates, it periodically pushes the duster plate 907 to reciprocate along the second slide bar 908. Under the reset action of the second spring 909, a high-frequency vibration is generated. This vibration is directly transmitted to the brush head 15, which thoroughly shakes off the dander, dust and other impurities accumulated in its gaps, creating favorable conditions for subsequent negative pressure adsorption.

[0021] A cleaning frame 911 is slidably installed inside the dust collection box 901, and the cleaning frame 911 is slidably sleeved with the filter cartridge 905. A third slide rod 912 is fixedly installed inside the dust collection box 901, and the cleaning frame 911 is slidably sleeved with the third slide rod 912. Two sets of symmetrically distributed third springs 913 are fitted on the third slide rod 912, and the two ends of the two sets of third springs 913 are fixedly connected to the cleaning frame 911 and the dust collection box 901, respectively. A connecting rod 914 is rotatably installed on the cleaning frame 911. A crank 915 is rotatably installed inside the dust collection box 901, and the crank 915 is rotatably connected to the end of the connecting rod 914 away from the cleaning frame 911 through a rotating shaft. The motor drives the crank 915 to rotate, and the crank 915 drives the cleaning frame 911 to reciprocate along the third slide rod 912 through the connecting rod 914, forming a smooth reciprocating stroke with the assistance of the third spring 913. During its movement, the cleaning rack 911 continuously scrapes away the accumulated dust adhering to the outer surface of the filter cartridge 905, preventing the filter holes from becoming clogged and ensuring that the filtration system maintains stable working efficiency over a long period of time.

[0022] In this embodiment, during equipment operation, the take-up roller 5 drives the parchment paper 2 to move at a constant speed, while the rotating roller 10 drives the circularly distributed brush heads 15 on its surface to rotate at high speed, performing brushing and abrasion treatment on the paper surface. The brush heads 15, through the sliding cooperation of the support rod 14 and the first slide rod 12, form an elastic telescopic structure under the buffering action of two sets of first springs 13, enabling them to adapt to the natural undulations and tension fluctuations of the parchment paper 2 surface, achieving dynamic pressure adjustment, thereby ensuring that the entire parchment paper 2 obtains a uniform and consistent softening effect. At the same time, the integrated dust removal system operates synchronously, and the mounting frame... The motor on 906 drives the cam 910 to rotate, and the duster 907 performs high-frequency reciprocating motion under the drive of the cam 910, thoroughly shaking off the dander, dust, and other impurities accumulated in the gaps of the brush head 15. The dust collection box 901, through the suction generated by the negative pressure fan 902, draws the suspended impurities into the box through the suction port 903 and the hose, where they are filtered and purified by the multi-layer filter cartridge 905. Inside the dust collection box 901, the cleaning rack 911, driven by the crank 915 and connecting rod mechanism, reciprocates along the third slide rod 912, continuously scraping away the dust accumulated on the outer surface of the filter cartridge 905, keeping the filtration system unobstructed. This collaborative working mechanism not only ensures the quality of the parchment paper 2's softness treatment but also achieves self-cleaning and dust control during the production process, effectively improving product cleanliness and production efficiency.
