Description

Technical Field

[0001] This invention relates to the field of graphene drying technology, and in particular to a drying device for preparing paper-based graphene composite substrates. Background Technology

[0002] Graphene, with its two-dimensional (2D) planar structure, unique electronic and optical properties, excellent mechanical stability, and good biocompatibility, gives graphene-based SERS substrates a unique advantage in detecting ultra-trace substances and has shown promising application prospects in various fields. In recent years, paper-based SERS substrates have been developed into a series of flexible graphene-paper composite substrates with excellent reinforcing properties due to their advantages such as low cost, good flexibility, portability, and mass production capability.

[0003] Based on the above search results and existing technologies, the following findings were made:

[0004] In existing graphene composite substrate preparation processes, drying temperature and drying time significantly affect the activity of SERS substrates. To obtain graphene composite substrates with high sensitivity, good stability, and high reproducibility, the spraying of graphene composite nanosol and the drying of paper substrates are integrated. This not only improves the substrate preparation speed but also ensures the uniformity, stability, and repeatability of substrate activity. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention proposes a drying device for preparing paper-based graphene composite substrates. A rotating motor drives an L-shaped column to rotate circumferentially, which in turn drives a U-shaped rack to reciprocate. The movement of the U-shaped rack drives a gear, a rotating tube, and an air jet pipe to oscillate back and forth, thereby ensuring that the air jet pipe sprays air evenly onto the paper-based composite substrate, thus improving the drying effect on the paper-based composite substrate.

The drying unit includes two rotating holes on the top of the protective plate, each with a rotating tube rotatably connected to it. Air jets are fixedly connected to the bottom ends of each of the rotating tubes, and gears are fixedly fitted onto each of the rotating tubes. A mounting plate is fixedly connected to the top of the protective plate, and a rotating motor is fixedly connected to the mounting plate. An L-shaped column is fixedly connected to the output end of the rotating motor. A U-shaped rack is located above the protective plate, and two gears mesh with the U-shaped rack. A strip-shaped hole is formed on the U-shaped rack, and the bottom end of the L-shaped column extends into the strip-shaped hole. A warm air box is fixedly connected to one side of the protective plate, and a fan is fixedly connected to the top of the warm air box. A connecting pipe is fixedly connected to the outlet end of the fan, and the top ends of the two rotating tubes are rotatably connected to the connecting pipe.

[0009] Preferably, the sol unit includes two brackets fixedly connected to the inner walls of both sides of the protective plate, and a spray pipe is rotatably connected to each pair of brackets. A U-shaped block is fixedly connected to one end of each of the two spray pipes. Two sliding holes are opened at the top of the protective plate, and a U-shaped movable rod is slidably connected in the two sliding holes. A fixed post is fixedly connected to the bottom end of each U-shaped movable rod, and one end of each of the two fixed posts extends into the two U-shaped movable rods.

[0010] Preferably, the mounting plate has a limiting hole, and a bending strip is slidably connected in the limiting hole. One end of the bending strip is fixedly connected to the U-shaped rack, and the bent end of the bending strip is in contact with the U-shaped movable rod.

[0011] Preferably, the U-shaped movable rod is fixedly sleeved with two fixed rings, and each U-shaped movable rod is sleeved with a telescopic spring, the two ends of which are fixedly connected to the fixed rings and the protective plate, respectively.

[0012] Preferably, a material pool is fixedly connected to the bottom of the base, a water pump is fixedly connected to one side of the material pool, a discharge pipe is fixedly connected to the discharge end of the water pump, a U-shaped pipe is fixedly connected to one end of the discharge pipe, and one end of each of the two spray pipes is rotatably connected to the two top ends of the U-shaped pipe.

[0013] Preferably, two connecting brackets are fixedly connected to the U-shaped tube, and one end of each connecting bracket is fixedly connected to the top of the material pool.

[0014] Preferably, the conveying unit includes a servo motor fixedly connected to the fixed frame, the output end of the servo motor is connected to a threaded rod via a coupling, the threaded rod is rotatably connected to the fixed frame, a slider is slidably connected to the fixed frame, the slider is screwed to the threaded rod, and a U-shaped plate is fixedly connected to the bottom of the slider.

[0015] Preferably, two movable holes are provided on one side of the U-shaped plate, and a sliding rod is slidably connected in each of the two movable holes. A pressure plate is fixedly connected to one end of each of the two sliding rods, and a fixing strip is fixedly connected to the other end of the two sliding rods. A return spring is sleeved on each of the two sliding rods, and the two ends of the return spring are fixedly connected to the U-shaped plate and the fixing strip, respectively.

[0016] Preferably, an L-shaped rod is fixedly connected to one side of the fixing frame, an extrusion column is fixedly connected to one end of the L-shaped rod, an inclined plate is fixedly connected to one side of the fixing strip, and the extrusion column is in contact with the inclined plate.

[0017] Compared with existing technologies, the significant advantages of this invention are:

[0018] Firstly, this invention, through the setting of the conveying unit, uses a servo motor to drive the threaded rod to rotate. The rotation of the threaded rod causes the slider and U-shaped plate to move. The U-shaped plate causes the paper substrate to move. The movement of the U-shaped plate causes the sliding rod, the fixing bar, and the inclined plate to move, so that the inclined plate moves away from the extrusion column. Since the return spring is in a stretched state, the return spring causes the fixing bar and the inclined plate to reset. The reset of the fixing bar causes the sliding rod and the pressure plate to reset, so that the pressure plate fixes the paper substrate.

[0019] Secondly, this invention utilizes a sol-gel unit. A rotating motor drives an L-shaped column to rotate in a circular motion. The rotation of the L-shaped column causes a U-shaped rack to reciprocate. The movement of the U-shaped rack causes a bending strip to reciprocate. When the bending strip moves towards the U-shaped plate, it presses the U-shaped movable rod downwards. The movement of the U-shaped movable rod causes the fixed column to move downwards. The movement of the fixed column presses the U-shaped block and the spray tube downwards. When the bending strip moves towards the connecting pipe, a telescopic spring causes the fixed ring and the U-shaped movable rod to reset. The U-shaped movable rod, through the fixed column, causes the U-shaped block and the spray tube to reset, allowing the spray tube to spray evenly. This allows the slider to move the paper substrate to the position of the spray tube for even spraying, thereby improving the coating effect on the paper substrate.

[0020] Thirdly, the present invention, through the setting of the drying unit, uses a fan to draw air from the warm air box, and then sprays it out through the connecting pipe and rotating pipe via the jet pipe. The rotating motor drives the L-shaped column to rotate in a circle, and the rotation of the L-shaped column drives the U-shaped rack to move back and forth. The movement of the U-shaped rack drives the gear, rotating pipe and jet pipe to swing back and forth, so that the jet pipe sprays air evenly onto the paper composite substrate, thereby improving the drying effect of the paper composite substrate.

[0031] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides an improved drying apparatus for preparing paper-based graphene composite substrates. The technical solution of this invention is as follows:

[0033] like Figures 1-7 As shown, a drying device for preparing paper-based graphene composite substrates includes a base 1, a protective plate 11 fixedly connected to the top of the base 1, and fixed plates 12 fixedly connected to both ends of the protective plate 11. A fixing frame 13 is fixedly connected to the bottom of both fixed plates 12. The device also includes:

[0034] A paper composite substrate drying mechanism is located on the protective plate 11;

[0035] The paper composite substrate drying mechanism includes a conveying unit, a solvent unit, and a drying unit. The drying unit includes two rotating holes on the top of a protective plate 11, each with a rotating tube 26 rotatably connected to it. Air jets 27 are fixedly connected to the bottom ends of each rotating tube 26, and gears 25 are fixedly fitted onto each rotating tube 26. A mounting plate 2 is fixedly connected to the top of the protective plate 11, and a rotating motor 21 is fixedly connected to the mounting plate 2. An L-shaped column 22 is fixedly connected to the output end of the rotating motor 21. A U-shaped rack 23 is located above the protective plate 11, with two gears 25 meshing on it. A strip-shaped hole 24 is formed on the U-shaped rack 23, and the bottom end of the L-shaped column 22 extends into the strip-shaped hole 24. One side of the protective plate 11... A warm air box 210 is fixedly connected, and a fan 29 is fixedly connected to the top of the warm air box 210. A connecting pipe 28 is fixedly connected to the air outlet of the fan 29, and the top ends of two rotating pipes 26 are respectively rotatably connected to the connecting pipe 28. Through the setting of the drying unit, the fan 29 drives the warm air box 210 to draw air, and then sprays it out through the connecting pipe 28 and the rotating pipe 26 through the jet pipe 27. The rotating motor 21 is started to drive the L-shaped column 22 to rotate in a circle. The rotation of the L-shaped column 22 drives the U-shaped rack 23 to move back and forth. The movement of the U-shaped rack 23 drives the gear 25, the rotating pipe 26 and the jet pipe 27 to swing back and forth, so that the jet pipe 27 sprays air evenly onto the paper composite substrate, thereby improving the drying effect of the paper composite substrate.

[0036] Furthermore, the sol unit includes two brackets 3 fixedly connected to the inner walls of both sides of the protective plate 11. A spray pipe 31 is rotatably connected to each pair of brackets 3. A U-shaped block 32 is fixedly connected to one end of each spray pipe 31. Two sliding holes are opened at the top of the protective plate 11, and a U-shaped movable rod 34 is slidably connected within each of the two sliding holes. A fixing post 33 is fixedly connected to the bottom end of each U-shaped movable rod 34. One end of each fixing post 33 extends into the two U-shaped movable rods 34. Limiting holes are opened on the mounting plate 2, and a bending strip 36 is slidably connected within the limiting holes. One end of the bending strip 36 is fixedly connected to a U-shaped rack 23, and the bent end of the bending strip 36 contacts the U-shaped movable rod 34. Two fixing rings 312 are fixedly sleeved on the U-shaped movable rod 34, and a telescopic spring 35 is sleeved on each U-shaped movable rod 34. Both ends are fixedly connected to the fixing ring 312 and the protective plate 11 respectively. With the setting of the sol unit, the U-shaped rack 23 moves and drives the bending strip 36 to move back and forth. When the bending strip 36 moves towards the U-shaped plate 17, the bending strip 36 squeezes the U-shaped movable rod 34 to move downward. The movement of the U-shaped movable rod 34 drives the fixing column 33 to move downward. The movement of the fixing column 33 squeezes the U-shaped block 32 and the spray tube 31 to rotate downward. When the bending strip 36 moves towards the connecting tube 28, the telescopic spring 35 drives the fixing ring 312 and the U-shaped movable rod 34 to reset. The U-shaped movable rod 34 drives the U-shaped block 32 and the spray tube 31 to reset through the fixing column 33, so that the spray tube 31 can spray evenly. This allows the slider 16 to move the paper substrate to the position of the spray tube 31 for even spraying, thereby improving the spraying effect on the paper substrate.

[0037] Furthermore, a material tank 310 is fixedly connected to the bottom of the base 1, a water pump 39 is fixedly connected to one side of the material tank 310, a discharge pipe 38 is fixedly connected to the discharge end of the water pump 39, a U-shaped pipe 37 is fixedly connected to one end of the discharge pipe 38, and one end of each of the two spray pipes 31 is rotatably connected to the two top ends of the U-shaped pipe 37. Through the setting of the material tank 310, the water pump 39 draws out the solution from the material tank 310, and then sprays it out through the discharge pipe 38 and the U-shaped pipe 37 from the spray pipe 31, thereby realizing the spraying of the paper substrate and the recycling of the residual material.

[0038] Furthermore, two connecting brackets 311 are fixedly connected to the U-shaped tube 37, and one end of each connecting bracket 311 is fixedly connected to the top of the material pool 310; the connecting brackets 311 are used to support the U-shaped tube 37.

[0039] Furthermore, the conveying unit includes a servo motor 14 fixedly connected to the fixed frame 13. The output end of the servo motor 14 is connected to a threaded rod 15 via a coupling. The threaded rod 15 is rotatably connected to the fixed frame 13. A slider 16 is slidably connected to the fixed frame 13. The slider 16 is screwed onto the threaded rod 15. A U-shaped plate 17 is fixedly connected to the bottom of the slider 16. Through the setting of the threaded rod 15, the servo motor 14 drives the threaded rod 15 to rotate. The rotation of the threaded rod 15 drives the slider 16 and the U-shaped plate 17 to move. The U-shaped plate 17 drives the paper substrate to move, thereby realizing the feeding of the paper substrate.

[0040] Furthermore, two movable holes are provided on one side of the U-shaped plate 17, and sliding rods 18 are slidably connected in both movable holes. One end of each sliding rod 18 is fixedly connected to a pressure plate 19, and the other end of each sliding rod 18 is fixedly connected to a fixing strip 110. A return spring 114 is sleeved on each sliding rod 18, and the two ends of the return spring 114 are fixedly connected to the U-shaped plate 17 and the fixing strip 110, respectively. An L-shaped rod 112 is fixedly connected to one side of the fixing frame 13, and a pressing column 11 is fixedly connected to one end of the L-shaped rod 112. 3. A sloping plate 111 is fixedly connected to one side of the fixing strip 110, and the pressing column 113 is in contact with the sloping plate 111. With the setting of the pressing column 113, the U-shaped plate 17 moves, which drives the sliding rod 18, the fixing strip 110 and the sloping plate 111 to move, so that the sloping plate 111 moves away from the pressing column 113. Since the return spring 114 is in a stretched state, the return spring 114 drives the fixing strip 110 and the sloping plate 111 to reset. The reset of the fixing strip 110 drives the sliding rod 18 and the pressure plate 19 to reset, so that the pressure plate 19 fixes the paper substrate.

[0041] The specific working method is as follows: During use, the paper substrate is placed inside the U-shaped plate 17. The servo motor 14 is started, driving the threaded rod 15 to rotate. The rotation of the threaded rod 15 causes the slider 16 and the U-shaped plate 17 to move towards the servo motor 14. The movement of the U-shaped plate 17 causes the sliding rod 18, the fixing bar 110, and the inclined plate 111 to move, moving the inclined plate 111 away from the pressing column 113. Because the return spring 114 is in a stretched state, it causes the fixing bar 110 and the inclined plate 111 to reset. The reset of the fixing bar 110 causes the sliding rod 18 and the pressing column 111 to reset. Plate 19 is reset, fixing the paper substrate in place. Water pump 39 is activated to extract the solution from material tank 310, which is then ejected through discharge pipe 38 and U-shaped pipe 37 from spray pipe 31. Fan 29 is activated to ventilate warm air box 210, and the solution is ejected through connecting pipe 28 and rotating pipe 26 from spray pipe 27. Rotating motor 21 is activated to drive L-shaped column 22 to rotate in a circular motion. The rotation of L-shaped column 22 drives U-shaped rack 23 to reciprocate, and the movement of U-shaped rack 23 drives gear 25, rotating pipe 26, and spray pipe 27 to oscillate, causing the air to spray... Pipe 27 can spray air evenly. The movement of U-shaped rack 23 drives the bending strip 36 to move back and forth. When the bending strip 36 moves towards U-shaped plate 17, it presses the U-shaped movable rod 34 downward. The movement of the U-shaped movable rod 34 drives the fixed ring 312 to move. The movement of the fixed ring 312 causes the telescopic spring 35 to compress and undergo elastic deformation. The movement of the U-shaped movable rod 34 drives the fixed column 33 to move downward. The movement of the fixed column 33 presses the U-shaped block 32 and the spray pipe 31 to rotate downward. When the bending strip 36 moves towards connecting pipe 28, the telescopic spring 35 drives the fixed ring... 312. The U-shaped movable rod 34 is reset. The U-shaped movable rod 34 drives the U-shaped block 32 and the spray pipe 31 to reset through the fixed column 33, so that the spray pipe 31 can spray evenly. The slider 16 drives the paper substrate to the position of the spray pipe 31 for even spraying, thereby improving the spraying effect on the paper substrate. Then it moves to the position of the air jet pipe 27 for even air jetting, thereby improving the drying effect on the paper composite substrate. After drying is completed, the slider 16 drives the paper composite substrate to move continuously and remove it from the protective shell. The worker can then take out the paper composite substrate.
