Abstract
Description
Technical Field
[0001] This invention belongs to the field of engineered wood processing, and specifically relates to a rapid cooling device for engineered wood. Background Technology
[0002] Wood-based panels are boards or molded products made from wood or other non-wood plant materials, which are separated into various unit materials through certain mechanical processing, and then bonded together with or without adhesives and other additives. They mainly include three categories of products: plywood, particleboard, and fiberboard. There are hundreds of extended products and deep-processed products. Among them, straw-based panels are wood-based panels made from straw as raw material.
[0003] Chinese Patent No. CN215038442U discloses a cooling device for processing engineered wood panels. The device includes a perforated panel with side plates welded to both sides of the top outer wall. Frames are bolted to both ends of the top outer wall of the side plates. A fan is bolted to the center of the top outer wall of the frame, and a ring pipe is bolted to the outer wall of the fan. A branch pipe is welded to the outer wall of the adjacent side of the ring pipe, and a water supply pipe is threadedly connected to the adjacent end of the branch pipe via a three-way valve. A filter screen is welded to the top outer wall of the fan. When the fan drives airflow towards the engineered wood panel, it directs cooling water sprayed from the atomizing nozzle to the panel for cooling, greatly improving the cooling efficiency. A motor drives a conveyor roller via a combination of sprockets and chains, enabling the engineered wood panel to be conveyed and cooled, significantly improving the efficiency of engineered wood panel processing and saving manpower. As can be seen from the above structure, freshly processed engineered wood panels are mostly in a high-temperature state. Generally, water mist cooling is used to reduce the temperature of the panels. When the surface of the engineered wood panels is covered with wood chips and dust generated during the production process, the dust will form a loose barrier layer on the surface of the panels. When the water mist comes into contact with the panels, it will be blocked by this dust layer and cannot directly act on the surface of the engineered wood panel substrate, thus failing to achieve efficient cooling. Summary of the Invention
[0004] In view of the problems mentioned in the background art, the purpose of this invention is to provide a rapid cooling device for engineered wood panels to solve the problems mentioned in the background art.
[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A rapid cooling device for engineered wood panels includes a conveying assembly, a cooling assembly at the lower end of the conveying assembly, a mounting frame fixedly connected to the upper end of the conveying assembly, a pressing assembly fixedly connected inside the mounting frame, a cleaning assembly fixedly connected to the upper end of the pressing assembly, the cleaning assembly including a mounting bracket disposed on the upper end of the pressing assembly, a cleaning roller rotatably connected to the inner side of the mounting bracket, a cleaning brush fixedly connected to the outer surface of the cleaning roller, a driven gear fixedly connected to the end of the cleaning roller through the mounting bracket, a driving gear rotatably connected to the outer side of the mounting bracket, the driving gear meshing with the driven gear, a cleaning motor fixedly connected to the outer side of the mounting bracket, and the output shaft of the cleaning motor fixedly connected to the driving gear.
[0006] As a preferred technical solution, the conveying assembly includes a conveying frame, with multiple shafts rotatably connected inside the conveying frame, conveying rollers fixedly connected to the outer side of the shafts, and a conveying motor fixedly connected to the outer side of the conveying frame.
[0007] As a preferred technical solution, the upper end of the conveyor frame is provided with an operating groove, the inside of the operating groove is rotatably connected to a drive rod, the outer surface of the drive rod is fixedly connected to a driving bevel gear, the other end of the shaft passes through the operating groove and is fixedly connected to a driven bevel gear, the driving bevel gear and the driven bevel gear are meshed with each other, and the output shaft of the conveyor motor is fixedly connected to the drive rod.
[0008] As a preferred technical solution, the cooling component includes a water tank fixedly connected to the lower end of the conveyor frame, a water pump fixedly connected to one side of the water tank, a water inlet chamber fixedly connected inside the mounting frame, an atomizing nozzle fixedly connected to the lower end of the water inlet chamber, a connecting pipe fixedly connected to the other end of the water pump, and the other end of the connecting pipe fixedly connected to the water inlet chamber.
[0009] As a preferred technical solution, an observation slot is provided on the outside of the water tank, and an observation plate is fixedly connected inside the observation slot. The observation plate and the observation slot are sealed to each other, and an observation scale is fixedly connected to the surface of the observation plate.
[0010] As a preferred technical solution, the clamping assembly includes connecting support rods disposed on both sides inside the mounting frame, with a clamping frame fixedly connected to the other end of the connecting support rods, and clamping rollers rotatably connected to the inner side of the clamping frame.
[0011] As a preferred technical solution, the connecting support rod includes a fixed sleeve rod fixedly connected inside the mounting frame. A compression spring is fixedly connected inside the fixed sleeve rod, and a movable insert rod is fixedly connected to the other end of the compression spring. The movable insert rod and the fixed sleeve rod are interlocked.
[0012] In summary, the present invention has the following main beneficial effects: First, start the cleaning motor on the outside of the mounting frame. The output shaft of the cleaning motor will drive the drive gear to rotate. Through the meshing transmission of the gear, the driven gear and the cleaning roller fixed to it will rotate synchronously inside the mounting frame. The cleaning brush on the outer surface of the cleaning roller will rotate continuously. At the same time, the conveying component will carry the artificial board at a uniform speed under the cleaning roller. The rotating cleaning brush will brush against the surface of the artificial board to complete the cleaning operation. At the same time, the clamping component will form a stable limit on the artificial board to prevent the artificial board from shifting during the conveying and cleaning process. This ensures that the cleaning brush can act evenly on every area of the board surface. First, it can remove the wood chips, dust and processing debris attached to the artificial board during production and conveying. This prevents these debris from entering the splicing, edge banding, and veneer structures of the artificial board in subsequent processing steps, affecting the processing accuracy and structural stability of the artificial board. Second, the flexible contact of the cleaning brush will not damage the surface of the artificial board, avoiding damage to the flatness and finishing effect of the artificial board surface, and ensuring the appearance quality of the artificial board. Secondly, as the engineered wood panel moves with the conveying assembly and passes under the cleaning assembly for cleaning, the connecting rods on both sides inside the mounting frame provide support for the clamping frame. The engineered wood panel passes under the clamping roller inside the clamping frame. At this time, the pressure spring inside the fixed sleeve continuously releases its elastic force, pushing the movable insert rod to extend outward along the inside of the fixed sleeve. This causes the clamping frame and clamping roller to move closer to the surface of the engineered wood panel. The clamping roller will fit against the surface of the engineered wood panel and passively rotate as the engineered wood panel is conveyed. First, the elastic force of the pressure spring can automatically adjust the clamping amplitude according to the thickness of the engineered wood panel, adapting to engineered wood panels of different thicknesses and always maintaining a stable limit on the engineered wood panel, avoiding displacement or warping of the engineered wood panel during conveying and cleaning, and ensuring that the cleaning brush can evenly cover the board surface without any cleaning dead corners.

[0015] Example refer to Figures 1 to 4 This embodiment of a rapid cooling device for engineered wood panels includes a conveying assembly 1, a cooling assembly 2 at the lower end of the conveying assembly 1, a mounting frame 3 fixedly connected to the upper end of the conveying assembly 1, a pressing assembly 4 fixedly connected inside the mounting frame 3, a cleaning assembly 5 fixedly connected to the upper end of the pressing assembly 4, the cleaning assembly 5 including a mounting bracket 51 disposed on the upper end of the pressing assembly 4, a cleaning roller 53 rotatably connected to the inner side of the mounting bracket 51, a cleaning brush 54 fixedly connected to the outer surface of the cleaning roller 53, a driven gear 55 fixedly connected to the end of the cleaning roller 53 through the mounting bracket 51, a driving gear 56 rotatably connected to the outer side of the mounting bracket 51, the driving gear 56 meshing with the driven gear 55, a cleaning motor 52 fixedly connected to the outer side of the mounting bracket 51, and the output shaft of the cleaning motor 52 fixedly connected to the driving gear 56.
[0016] refer to Figure 1 and Figure 3The conveying assembly 1 includes a conveying frame 11. Multiple shafts 12 are rotatably connected inside the conveying frame 11. Conveying rollers 13 are fixedly connected to the outer sides of the shafts 12. A conveying motor 14 is fixedly connected to the outer side of the conveying frame 11. An operating groove 15 is provided at the upper end of the conveying frame 11. A drive rod 16 is rotatably connected inside the operating groove 15. A driving bevel gear 17 is fixedly connected to the outer surface of the drive rod 16. The other end of the shaft 12 passes through the operating groove 15 and is fixedly connected to a driven bevel gear 18. The driving bevel gear 17 and the driven bevel gear 18 are meshed together. The output shaft of the conveying motor 14 is fixedly connected to the drive rod 16. The conveying motor on the outer side of the conveying frame 11 is activated. 14. The output shaft of the conveyor motor 14 will drive the drive rod 16 inside the operating groove 15 to rotate synchronously. The active bevel gear 17 on the outer surface of the drive rod 16 will rotate together. Through the meshing transmission between the active bevel gear 17 and the driven bevel gear 18 at the end of the shaft 12, the driving force is transmitted to all shafts 12 connected to the driven bevel gear 18. The shaft 12 will carry the outer fixed conveyor roller 13 to rotate synchronously inside the conveyor frame 11. At this time, the artificial board is placed on the upper end of the conveyor roller 13. The rotating conveyor roller 13 will drive the artificial board to move at a constant speed along the extension direction of the conveyor frame 11 through the friction with the bottom surface of the artificial board, thus completing the conveying operation of the artificial board.
[0017] refer to Figure 1 and Figure 2 The cooling component 2 includes a water tank 21 fixedly connected to the lower end of the conveyor frame 11. A water pump 22 is fixedly connected to one side of the water tank 21. A water inlet chamber 24 is fixedly connected inside the mounting frame 3. An atomizing nozzle 25 is fixedly connected to the lower end of the water inlet chamber 24. A connecting pipe 23 is fixedly connected to the other end of the water pump 22. The other end of the connecting pipe 23 is fixedly connected to the water inlet chamber 24. During the process of conveying the artificial board with the conveyor component 1, the water pump 22 on one side of the water tank 21 is started. The water pump 22 will draw the cooling water stored inside the water tank 21 and deliver the water to the water inlet chamber 24 inside the mounting frame 3 through the connecting pipe 23. The water inlet chamber 24 will temporarily store and divert the incoming water flow. Then the water flow will be sprayed out from the atomizing nozzle 25 at the lower end of the water inlet chamber 24 to form a fine water mist. This water mist will directly contact the surface of the artificial board on the conveyor component 1. Through the vaporization and heat absorption of the water mist, the residual heat in the artificial board processing is carried away, achieving the cooling effect.
[0018] refer to Figure 1An observation slot 6 is provided on the outside of the water tank 21. An observation plate 7 is fixedly connected inside the observation slot 6. The observation plate 7 and the observation slot 6 are sealed to each other. An observation scale 8 is fixedly connected to the surface of the observation plate 7. During the operation of the cooling component 2, the sealed observation plate 7 inside the observation slot 6 on the outside of the water tank 21 will isolate the water inside the water tank 21 from contact with the outside air, preventing the cooling water inside the water tank 21 from falling into dust or being lost due to evaporation. At the same time, it allows the staff to directly observe the water level inside the water tank 21 through the observation plate 7.
[0019] refer to Figure 1 , Figure 2 and Figure 4 The clamping assembly 4 includes connecting support rods 41 disposed on both sides inside the mounting frame 3. A clamping frame 42 is fixedly connected to the other end of each connecting support rod 41. A clamping roller 43 is rotatably connected to the inner side of each clamping frame 42. Each connecting support rod 41 includes a fixed sleeve rod 411 fixedly connected inside the mounting frame 3. A pressure spring 412 is fixedly connected inside the fixed sleeve rod 411. A movable insert rod 413 is fixedly connected to the other end of the pressure spring 412. The movable insert rod 413 and the fixed sleeve rod 411 are interlocked. When the artificial board moves with the conveying assembly 1 and passes under the cleaning assembly 5 for cleaning operations, the connecting support rods 41 on both sides inside the mounting frame 3... The clamping frame 42 will provide support, and the artificial board will pass under the clamping roller 43 inside the clamping frame 42. At this time, the pressure spring 412 inside the fixed sleeve 411 will continuously release the elastic force, pushing the movable insert 413 to extend outward along the inside of the fixed sleeve 411, thereby driving the clamping frame 42 and the clamping roller 43 to move closer to the surface of the artificial board. The clamping roller 43 will fit against the surface of the artificial board and passively rotate as the artificial board is conveyed. First, the elastic force of the pressure spring 412 can automatically adjust the clamping amplitude according to the thickness of the artificial board, adapting to artificial boards of different thicknesses and always maintaining a stable limit on the artificial board.
[0020] Operating principle and advantages: Before starting the operation, the operator can quickly check the cooling water storage in the water tank 21 by observing the sealed observation plate 7 in the observation slot 6 on the outside of the water tank 21 and the observation scale 8 on the surface of the observation plate 7. If the water level is lower than the preset scale threshold, clean water should be added to the water tank 21 in time. The sealed connection structure of the observation plate 7 can prevent external dust from falling into the water tank 21 and contaminating the water, while reducing the natural evaporation loss of water in the water tank 21. After the equipment is started, the conveyor motor 14 on the outside of the conveyor frame 11 is started first. The output shaft of the conveyor motor 14 drives the drive rod 16 in the operating slot 15 at the upper end of the conveyor frame 11 to rotate. The active bevel gear 17 on the outer surface of the drive rod 16 will engage with all the through-operation gears. The driven bevel gear 18 at the end of the shaft 12 of the groove 15 engages and drives all shafts 12 to rotate synchronously. The shafts 12 drive the outer fixed conveyor rollers 13 to rotate at a constant speed inside the conveyor frame 11. At this time, the artificial board to be cooled is placed on the upper end of the conveyor rollers 13. The conveyor rollers 13, through friction with the bottom surface of the artificial board, drive the artificial board to move smoothly along the extension direction of the conveyor frame 11. When the artificial board moves to the inner area of the mounting frame 3, the pressure springs 412 inside the fixed sleeves 411 connecting the support rods 41 on both sides of the mounting frame 3 will release the elastic force, pushing the movable insert rod 413 to extend outward along the axial direction of the fixed sleeves 411, driving the pressing frame 42 and the pressing rollers 43 inside the frame to press against the surface of the artificial board. During the surface bonding process, the pressing roller 43 passively rotates as the engineered wood panel is conveyed. This automatically adjusts the pressing range according to the thickness of the engineered wood panel, adapting to different specifications, and simultaneously provides stable positioning to prevent the panel from shifting or warping during transport. Simultaneously, the cleaning motor 52 on the outside of the mounting frame 51 is activated. The output shaft of the cleaning motor 52 drives the drive gear 56 to rotate. The drive gear 56 meshes with the driven gear 55 at the end of the cleaning roller 53, causing the cleaning roller 53 to rotate inside the mounting frame 51. The cleaning brush 54 on the outer surface of the cleaning roller 53 rotates at a uniform speed, sweeping the surface of the pressed and positioned engineered wood panel to remove sawdust, processing debris, and other contaminants. After cleaning up debris to prevent it from affecting the subsequent cooling effect, the water pump 22 on one side of the water tank 21 is started while the cleaning operation is underway. The water pump 22 draws clean water from the water tank 21 and delivers it to the water inlet chamber 24 inside the mounting frame 3 through the connecting pipe 23. After the water inlet chamber 24 temporarily stores and evenly distributes the water flow, the water will be sprayed out from the atomizing nozzle 25 at the lower end of the water inlet chamber 24, forming a fine water mist. The water mist will directly contact the cleaned surface of the artificial board. Through the vaporization and heat absorption of the water mist, the residual heat from the artificial board processing is quickly removed, completing the rapid cooling operation. Moreover, the cleaned board surface will not have water stains caused by water mist carrying dust, ensuring the quality of the artificial board surface.
