Description

Technical Field

[0001] The utility model relates to the technical field of sound-absorbing board production, in particular to a sound-absorbing board production drying device. Background Art

[0002] Sound-absorbing panels are a kind of decorative material with sound-absorbing and noise-reducing functions. During their production process, they need to be dried to prevent uneven shrinkage and deformation of the sound-absorbing panels as the moisture gradually evaporates during subsequent use. Therefore, a drying device is needed.

[0003] A Chinese patent with authorization publication number CN220885719U discloses a conveying structure for a dryer for producing sound-absorbing panels. The structure comprises a pair of side bottom plates with a connecting plate fixed between the tops of the side bottom plates. The drive rollers include axles with sprockets fixed at each end. A chain is wound around the two sprockets corresponding to the same side of the two pairs of drive rollers. The support base comprises two symmetrically arranged angle steels, the bottoms of which are fixed to the bottoms of the side bottom plates via legs. The device uses a chain drive to move the semi-finished sound-absorbing panels with support bars. The support bars reduce the area of coating adhesion, and the support bars and the semi-finished sound-absorbing panels are relatively static. The sound-absorbing panels are driven by the support bars at a stable speed, ensuring uniform drying of multiple sound-absorbing panels.

[0004] However, the above device still has some problems. In actual application, the operating area of the blowing assembly during drying is usually assembled in a fixed position, so that certain parts of the sound-absorbing panel can be effectively blown and dried, while other parts are difficult to fully dry, thereby reducing the drying effect of the sound-absorbing panel. Therefore, to address the above problems, a sound-absorbing panel production drying device is proposed. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the problems raised in the background art, the utility model provides a drying device for producing sound-absorbing panels.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A sound-absorbing board production and drying device of the present utility model includes a drying frame. One side of the drying frame is fixed with an L-shaped seat. A driving motor is installed inside the L-shaped seat. The output end of the driving motor is installed with a rotating shaft. A disc is installed on the outer side of the rotating shaft. A support rod is rotatably installed inside the disc. A connecting rod is installed on the outer wall of the support rod. A slide rail is opened inside one side of the drying frame. A sliding block is slidably installed inside the slide rail. An installation seat is installed on one side of the sliding block. One end of the connecting rod is installed inside the installation seat through a pin shaft. A blowing component is assembled on one side of the sliding block, enabling the blowing component to reciprocate inside the drying frame, expanding the operation area of the blowing component, ensuring that the surface of the sound-absorbing board can be evenly blown by hot air, thereby improving the drying effect.

[0007] Preferably, the blowing component includes a U-shaped pipe. Two chutes are symmetrically opened inside the drying frame. The two ends of the U-shaped pipe are respectively slidably installed inside the chutes. Connecting pipes are installed at one ends of the U-shaped pipes. Five conveying pipes are equidistantly installed on the outer side of the connecting pipes. Seven air nozzles are equidistantly installed on the outer wall of the conveying pipes, enabling hot air to blow towards the bottom side and the top side of the sound-absorbing board simultaneously, improving the drying efficiency and uniformity.

[0008] Preferably, an installation cavity is installed on the top side of the drying frame. An air inlet pipe is connected to the top side of the installation cavity. A negative pressure motor is installed on the top side of the installation cavity. Three fan blades are installed at the output end of the negative pressure motor. A heating grid plate is assembled in the middle of the installation cavity. An air supply pipe is connected to the bottom end of the installation cavity. A pump is installed on the outer wall of one end of the air supply pipe. The other end of the air supply pipe is communicated with the U-shaped pipe, providing a continuous and stable hot air source for the blowing component, and being able to effectively heat and dry the sound-absorbing board.

[0009] Preferably, the U-shaped pipe, the connecting pipe and the conveying pipe are all rigid straight pipes. The end of the air supply pipe where the pump is installed is a rigid pipe, and the end connected to the U-shaped pipe is a flexible pipe, which can ensure the stable transmission of hot air.

[0010] Preferably, rotating shafts are rotatably installed between the two sides at both ends of the drying frame. Rotating rollers are installed on the outer walls of the rotating shafts. A conveyor belt is jointly assembled on the outer sides of the rotating rollers. A conveying motor is installed on one side of the drying frame. One end of the rotating shaft is connected to the output end of the conveying motor in a matching manner. A number of through holes are opened inside the conveyor belt. The two ends of the U-shaped pipe are respectively located on the top side and the bottom side of the conveyor belt, realizing the automatic conveying operation of the sound-absorbing board, accelerating the drying process and improving the production efficiency.

[0011] Preferably, a control panel is installed on one side of the drying frame. The control panel is used to operate and control the electrical components inside the device, facilitating the operation and control of the electrical components in the device.

[0012] The advantages of the present utility model are as follows:

[0013] 1. When the driving motor of the present utility model is started, it drives the rotation of the rotating shaft and the disc. The support rod moves as the disc rotates, and the connecting rod moves accordingly, thereby driving the sliding block to reciprocate in the slide rail. Further, the blowing assembly drives the U-shaped tube to reciprocate in the chute, expanding the working area of the blowing assembly and ensuring that the surface of the sound-absorbing board can be evenly blown by hot air, thus improving the drying effect.

[0023] Please refer to Figures 1-5 As shown, a drying device for the production of sound-absorbing boards includes a drying frame 1. An L-shaped seat 2 is fixed on one side of the drying frame 1. A driving motor 3 is installed inside the L-shaped seat 2. A rotating shaft is installed at the output end of the driving motor 3. A disc 4 is installed on the outer side of the rotating shaft. A support rod 5 is rotatably installed inside the disc 4. A connecting rod 6 is installed on the outer wall of the support rod 5. A slide rail 7 is opened inside one side of the drying frame 1. A sliding block 8 is slidably installed inside the slide rail 7. A mounting seat 9 is installed on one side of the sliding block 8. One end of the connecting rod 6 is installed inside the mounting seat 9 through a pin shaft. A blowing component is assembled on one side of the sliding block 8;

[0024] The blowing component includes a U-shaped tube 10. Two chutes 11 are symmetrically opened inside the drying frame 1. The two ends of the U-shaped tube 10 are respectively slidably installed inside the chutes 11. Connecting pipes 12 are installed at one end of the U-shaped tube 10. Five conveying pipes 13 are equidistantly installed on the outer side of the connecting pipe 12. Seven air spraying nozzles 14 are equidistantly installed on the outer wall of the conveying pipe 13;

[0025] An installation cavity 15 is installed on the top side of the drying frame 1. An air inlet pipe 16 is connected to the top side of the installation cavity 15. A negative pressure motor 17 is installed on the top side of the installation cavity 15. Three fan blades 18 are installed at the output end of the negative pressure motor 17. A heating grid plate 19 is assembled in the middle of the installation cavity 15. A air supply pipe 21 is connected to the bottom end of the installation cavity 15. A pump 20 is installed on the outer wall of one end of the air supply pipe 21. The other end of the air supply pipe 21 is communicated with the U-shaped pipe 10. The U-shaped pipe 10, the connecting pipe 12 and the conveying pipe 13 are all rigid straight pipes. The end of the air supply pipe 21 where the pump 20 is installed is a rigid pipe, and the end connected to the U-shaped pipe 10 is a flexible pipe. A control panel 27 is installed on one side of the drying frame 1; During operation, in practical applications, the working area of the blowing component during drying is usually assembled at a fixed position, so that some parts of the sound-absorbing board can be effectively blown and dried, while other parts are difficult to be fully dried, thus reducing the drying effect on the sound-absorbing board. Start the negative pressure motor 17. The output end of the negative pressure motor 17 drives the three fan blades 18 to rotate, generating suction, sucking the outside air into the installation cavity 15 through the air inlet pipe 16. After the air enters the installation cavity 15, it is heated into hot air by the heating effect of the heating grid plate 19. At the same time, start the pump 20. The pump 20 transports the hot air in the installation cavity 15 to the inside of the U-shaped pipe 10, the connecting pipe 12 and the conveying pipe 13 through the air supply pipe 21. Finally, the hot air can be blown to the bottom side and the top side of the sound-absorbing board through the air spraying nozzle 14, improving the drying efficiency and uniformity. Moreover, the end of the air supply pipe 21 where the pump 20 is installed is a rigid pipe, ensuring the stability of the hot air transmission. The end connected to the U-shaped pipe 10 is a flexible pipe, facilitating the reciprocating movement of the U-shaped pipe 10 in the drying frame 1;

[0026] Start the driving motor 3 to drive the rotating shaft and the disc 4 to rotate. The support rod 5 moves as the disc 4 rotates, causing the connecting rod 6 to move accordingly. When the connecting rod 6 moves, it drives the sliding block 8 to reciprocate in the slide rail 7, and further causes the blowing component to drive the U-shaped pipe 10 to reciprocate inside the chute 11. With the reciprocating movement of the blowing component, the working area of the blowing component is expanded, ensuring that the surface of the sound-absorbing board can be evenly blown by the hot air, thereby improving the drying effect.

[0027] Please refer to Figures 1-3As shown in the figure, rotating shafts 22 are rotatably installed between both sides at the two ends of the drying frame 1. Rotating rollers 23 are installed on the outer walls of the rotating shafts 22. A conveyor belt 24 is jointly and cooperatively assembled on the outer sides of the rotating rollers 23. A conveyor motor 25 is installed on one side of the drying frame 1. One end of the rotating shaft 22 is cooperatively connected to the output end of the conveyor motor 25. A plurality of through holes 26 are formed inside the conveyor belt 24. Both ends of the U-shaped pipe 10 are respectively located on the top side and the bottom side of the conveyor belt 24. During operation, in the production process of the sound-absorbing board, in order to continuously dry the sound-absorbing board, the conveyor motor 25 is started. The output end of the conveyor motor 25 drives the rotating shaft 22 to rotate, so that the rotating roller 23 rotates accordingly, and then drives the conveyor belt 24 to operate. The sound-absorbing board to be dried is placed on the conveyor belt 24. Since a plurality of through holes 26 are formed inside the conveyor belt 24, on the one hand, the contact area between the conveyor belt 24 and the sound-absorbing board can be reduced, making it easier for the hot air to contact the bottom of the sound-absorbing board for drying; on the other hand, the through holes 26 also contribute to the circulation of the hot air, improving the drying efficiency.

[0028] Working principle: Start the conveyor motor 25. The output end of the conveyor motor 25 drives the rotating shaft 22 to rotate, so that the rotating roller 23 rotates accordingly, and then drives the conveyor belt 24 to operate. The sound-absorbing board to be dried is placed on the conveyor belt 24. Since a plurality of through holes 26 are formed inside the conveyor belt 24, on the one hand, the contact area between the conveyor belt 24 and the sound-absorbing board can be reduced, making it easier for the hot air to contact the bottom of the sound-absorbing board for drying; on the other hand, the through holes 26 also contribute to the circulation of the hot air, improving the drying efficiency.

[0029] Start the negative pressure motor 17. The output end of the negative pressure motor 17 drives the three fan blades 18 to rotate, generating suction force to suck the outside air into the installation cavity 15 through the air inlet pipe 16. After the air enters the installation cavity 15, it is heated into hot air by the heating action of the heating grid plate 19. At the same time, start the pump 20. The pump 20 transports the hot air in the installation cavity 15 to the inside of the U-shaped pipe 10, the connecting pipe 12 and the conveying pipe 13 through the air supply pipe 21. Finally, through the air spraying nozzles 14, the hot air can blow towards the bottom side and the top side of the sound-absorbing board simultaneously, improving the drying efficiency and uniformity. And the end of the air supply pipe 21 where the pump 20 is installed is a rigid pipe, ensuring the stability of the hot air transmission. The end connected to the U-shaped pipe 10 is a flexible pipe, facilitating the reciprocating movement of the U-shaped pipe 10 inside the drying frame 1.

[0030] Start the drive motor 3 to drive the rotating shaft and the disc 4 to rotate. The support rod 5 moves as the disc 4 rotates, causing the connecting rod 6 to move accordingly. When the connecting rod 6 moves, it drives the sliding block 8 to reciprocate in the slide rail 7, and then makes the blowing assembly drive the U-shaped pipe 10 to reciprocate inside the chute 11. With the reciprocating movement of the blowing assembly, the working area of the blowing assembly is expanded, ensuring that the surface of the sound-absorbing board can be evenly blown by the hot air, thereby improving the drying effect.
