Description

Technical Field

[0001] This utility model relates to the field of specialty paper production technology, specifically to a specialty paper high-dryness pressing and drying device. Background Technology

[0002] Specialty paper is paper made from different fibers using a paper machine to produce paper with special functions. For example, it can be made from raw materials such as synthetic fibers, synthetic pulp, or mixed wood pulp, and modified or processed with different materials to give the paper different functions and uses. These include paper for household use, building materials, electrical products, industrial filters, machinery industry, agriculture, information technology, optics, culture and art, and cutting-edge biotechnology. Any paper material used for special purposes is collectively referred to as specialty paper. Specialty paper usually requires pressing and drying during the production process to meet the requirements of post-production use.

[0003] For example, a Chinese authorized patent, publication number CN204199108U, describes a K-type press structure device for the production of specialty paper. This device includes a rubber roller, a vacuum roller, and a stone roller. The surface of the rubber roller contacts the surface of the vacuum roller, and the surface of the vacuum roller contacts the surface of the stone roller. All three components form a K-shaped structure. When producing double-sided glossy paper, the wet paper web from the wire section passes through a felt to the press roller and vacuum roller for squeezing and suction. After further squeezing and suction by the vacuum roller and stone roller to remove most of the moisture, the paper enters the drying cylinder via an arc-shaped roller for the next process, including drying. This press structure allows moisture to be discharged promptly through the felt on the inlet side, preventing it from flowing to the press zone inlet side. This results in lower paper shrinkage and deformation, and offers good flexibility and versatility.

[0004] The aforementioned traditional specialty paper production equipment uses multiple rollers working together to press out moisture. This structure is more complex to use. As the moisture content inside the specialty paper gradually decreases, the thickness of the specialty paper will decrease, and gaps are likely to exist between the rollers, resulting in insufficient subsequent pressing force, which is not conducive to the complete pressing and forming of the specialty paper.

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 protection scope of the present utility model.

[0029] Example

[0030] Reference Figure 1-6 As shown, a special paper high-dryness pressing and drying device includes a machine body 1. Two sets of supports 211 are fixed at the top of the machine body 1 and distributed front and rear. The inner walls of the two sets of supports 211 are rotatably connected to a drive roller 212 and a driven roller 214. A motor 213 is installed on the outer wall of any set of supports 211. The output end of the motor 213 is connected to the drive roller 212. The inner wall of the machine body 1 is connected to the driven roller 214 through an adjustment mechanism. The adjustment mechanism controls the up and down movement of the driven roller 214, thereby adjusting the gap between the driven roller 214 and the drive roller 212. This facilitates the pressing and drying of special paper of different thicknesses, improves the use effect of the equipment, and ensures that the pressing and drying of special paper of different thicknesses can be achieved through this adjustment method. The machine body 1 has a discharge port 314 on the side away from the drive roller 212. The top of the machine body 1 is equipped with a first dryer 311 and the bottom is equipped with a second dryer 312. Special paper passes through the machine body 1 and is discharged through the discharge port 314. After the first dryer 311 and the second dryer 312 are turned on, the upper and lower surfaces of the special paper can be dried.

[0031] The adjustment mechanism includes a sliding block 215, a sliding groove 216, a connecting plate 219, a hydraulic rod 220, and a collar 221. The driven roller 214 is rotatably connected to both ends of the sliding block 215. The bracket 211 has a sliding groove 216 inside that slidably connects to the sliding block 215. A connecting plate 219 is fixed to the inner wall of the machine body 1. A hydraulic rod 220 is mounted on the top of the connecting plate 219. The output end of the hydraulic rod 220 is connected to a collar 221 that rotatably connects to the outer wall of the driven roller 214. Activating the hydraulic rod 220 drives the collar 221 and the driven roller 214 to move vertically back and forth, thereby achieving automated control of the distance between the driven roller 214 and the driving roller 212. The sliding block 215 and sliding groove 216 ensure stable vertical movement of the driven roller 214, enhancing its adjustment effect. The outer wall of the sliding block 215 is fixed with a protrusion 217, and the inner wall of the sliding groove 216 is provided with a limiting groove 218 corresponding to the protrusion 217. The protrusion 217 and the limiting groove 218 can achieve a further stabilizing effect and prevent the sliding block 215 from falling off the sliding groove 216.

[0032] Vertical plates 222 are fixed on the inner wall of the machine body 1. A movable plate 223 is connected to the inner wall of the vertical plate 222 through an elastic mechanism. A pressure roller 224 is rotatably connected to the inner wall of the movable plate 223. Special paper passes through the vertical plate 222. Under the elastic mechanism, the movable plate 223 and the pressure roller 224 can be driven to press down continuously. The pressure roller 224 will stick to the surface of the special paper to achieve the purpose of further pressing. As the special paper is conveyed, the pressure roller 224 can rotate to press the special paper and achieve the purpose of squeezing out the internal moisture.

[0033] The elastic mechanism includes a first movable rod 225, a top plate 226, and a press spring 227. One end of the first movable rod 225 is inserted into the vertical plate 222 and fixed to the top of the movable plate 223, while the other end is fixed to the top plate 226. The press spring 227 is wrapped around the outer wall of the first movable rod 225. Both ends of the press spring 227 are connected to the vertical plate 222 and the top plate 226, respectively. In use, the top plate 226 can be pulled upward, which will drive the first movable rod 225, the movable plate 223, and the pressure roller 224 to move upward, thereby compressing the press spring 227. When the special paper passes through the vertical plate 222 and is located at the bottom of the pressure roller 224, the top plate 226 is released. Under the elasticity of the press spring 227, the pressure roller 224 can be driven to press down and reset, squeezing the special paper and achieving the purpose of pressing and draining. A second movable rod 228 is fixed to the top of the movable plate 223. The second movable rod 228 extends above the vertical plate 222 and is fixed with a baffle 229. The width of the baffle 229 is greater than the width of the second movable rod 228. As the movable plate 223 moves up and down, it can drive the second movable rod 228 to slide along the inner wall of the vertical plate 222. The baffle 229 can ensure that the second movable rod 228 will not fall off the vertical plate 222.

[0034] Several sets of guide rollers 313 are rotatably connected to the inner wall of the machine body 1. These guide rollers 313 are arranged in a reciprocating pattern from left to right. The first dryer 311 and the second dryer 312 are staggered left and right. The specialty paper is distributed in an "S" shape on the guide rollers 313. This arrangement increases the surface area of ​​the specialty paper within the machine body 1. The first dryer 311 and the second dryer 312 can perform comprehensive drying on both the top and bottom surfaces of the specialty paper, enhancing the drying efficiency. The first dryer 311 and the second dryer 312 include an electric heating wire and a fan structure. The fan blows air into the machine body 1, and the electric heating wire heats the air, bringing it into contact with the surface of the specialty paper, thereby achieving the drying effect.

[0035] Working principle: When needed, the special paper is passed between the drive roller 212 and the driven roller 214. Then, the hydraulic rod 220 is turned on to drive the collar 221 to move the driven roller 214 upward and press the special paper. After the motor 213 is turned on, the special paper is driven to the right. The drive roller 212 and the driven roller 214 can rotate in opposite directions to press the special paper, and the water inside can fall downward into the machine body 1.

[0036] The specialty paper passes through the vertical plate 222 and is located at the bottom of the pressure roller 224. By releasing the top plate 226, the movable plate 223 and the pressure roller 224 are driven to move downward under the elasticity of the pressure spring 227, so that the pressure roller 224 squeezes the specialty paper to achieve further squeezing. When the movable plate 223 moves downward, it will drive the second movable rod 228 to slide inside the vertical plate 222, ensuring the stability of the movement of the movable plate 223.

[0037] Finally, the specialty paper is wound from top to bottom and from left to right onto the outer wall of several sets of second dryers 312. The specialty paper can be distributed in an "S" shape and discharged through the discharge port 314. Then, the first dryer 311 and the second dryer 312 are turned on, which can perform comprehensive drying treatment on both the top and bottom sides of the specialty paper, thereby enhancing the drying efficiency of the specialty paper.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
