Description

Technical Field

[0001] The invention relates to the technical field of sound-absorbing cotton production, and in particular to a sound-absorbing cotton production and processing device. Background Art

[0002] Sound-absorbing cotton is a material used to absorb sound energy, reduce sound reflection and echo, thereby improving indoor noise, echo and reverberation problems.

[0003] The reason why sound-absorbing cotton can absorb sound is that there are a large number of tiny pores inside the sound-absorbing cotton. When sound waves encounter the pores, they will continue to reflect and refract, causing the sound waves to continue to propagate in the pores and rub against the pore walls. The sound energy is gradually converted into heat energy, thereby weakening and eventually absorbing the sound waves, reducing the reflection and echo of the sound.

[0004] However, in the production process of traditional sound-absorbing cotton, glue is often used to cover the sound-absorbing cotton in all directions and press and compound it so that multiple layers of sound-absorbing cotton form a whole. The sound-absorbing effect is improved by making the sound-absorbing cotton have a certain thickness, so that the sound waves are transmitted to the thicker sound-absorbing cotton to block and silence the noise. However, there is still a problem that the sound absorption effect is poor and the noise cannot be sealed in the sound-absorbing cotton.

[0005] To this end, the present invention proposes a sound-absorbing cotton production and processing device to solve the above problems. Summary of the invention

Figure 2 A glue storage box 101 is provided on the outer wall of the frame 1, and a connecting piece 102 is provided on one end of the composite part 32 close to the glue storage box 101. The connecting piece 102 is sealed and rotatably connected to the composite part 32. The conveying hole 324 is connected to the inner cavity of the glue storage box 101 through the connecting piece 102 and the pipeline. A one-way valve is provided in the pipeline between the glue storage box 101 and the connecting piece 102.

The outer wall of the frame 1 is respectively provided with motors for driving the first guide cylinder 23, the second guide cylinder 24, the first adjusting roller 41, the second adjusting roller 42 and the composite part 32 to rotate.

[0041] When in use, the combed and laid sound-absorbing cotton is respectively conveyed to the first conveying roller 25 and the first guide cylinder 23. As the first guide cylinder 23 rotates counterclockwise continuously under the action of the motor, the first guide cylinder 23 rotates on the outer wall of the first fixed shaft 21. When the first molded part 213 and the second molded part 214 contact the inner wall of the first guide cylinder 23 through the rotation of the first guide cylinder 23, the first molded part 213 and the second molded part 214 squeeze the first elastic part 212 to store energy. When the first guide cylinder 23 continues to rotate until the first limiting hole 231 is opposite to the first molded part 213 and the second molded part 214 respectively, When the first elastic member 212 relaxes and releases energy, the first molded member 213 and the second molded member 214 extend out of the first limiting hole 231. When the first molded member 213 moves in the first guide hole 211, the sound-absorbing cotton between the first conveying roller 25 and the first guide cylinder 23 is squeezed to form holes. The first molded member 213 relaxes and enters the sound-absorbing cotton when the first elastic member 212 relaxes, and the first molded member 213 forms holes at the contact position with the sound-absorbing cotton. When the sound-absorbing cotton is conveyed between the first guide cylinder 23 and the first conveying roller 25, the sound-absorbing cotton is close to one side of the first guide cylinder 23, forming a plurality of evenly distributed recesses pressed by the first molded member 213.

[0042] Similarly, as the second guide cylinder 24 continuously rotates clockwise under the action of the motor, the second guide cylinder 24 rotates on the outer wall of the second fixed shaft 22. When the third molded part 223 and the fourth molded part 224 contact the inner wall of the second guide cylinder 24 through the rotation of the second guide cylinder 24, the third molded part 223 and the fourth molded part 224 squeeze the second elastic part 222 to store energy. When the second guide cylinder 24 continues to rotate until the second limiting hole 241 is respectively opposite to the third molded part 223 and the fourth molded part 224, the second elastic part 222 relaxes and releases energy, so that the third molded part 223 and the fourth molded part 224 are respectively opposite to each other. The molded part 223 and the fourth molded part 224 extend out of the second limiting hole 241. When the fourth molded part 224 moves in the second guide hole 221, it squeezes and forms holes in the sound-absorbing cotton between the second conveying roller 26 and the second guide cylinder 24. The fourth molded part 224 enters the sound-absorbing cotton under the relaxation action of the second elastic part 222, and forms holes at the contact position between the fourth molded part 224 and the sound-absorbing cotton. When the sound-absorbing cotton is conveyed between the second guide cylinder 24 and the second conveying roller 26, the sound-absorbing cotton is close to one side of the second guide cylinder 24, forming a plurality of evenly distributed recesses pressed by the fourth molded part 224.

[0043] Similarly, the second molding part 214 and the third molding part 223 jointly form holes on the upper and lower surfaces of the sound-absorbing cotton located between the first guide cylinder 23 and the second guide cylinder 24, so that when the sound-absorbing cotton is transported between the first guide cylinder 23 and the second guide cylinder 24, a side of the sound-absorbing cotton close to the first guide cylinder 23 forms a plurality of evenly distributed concave holes pressed by the second molding part 214. Similarly, a side of the sound-absorbing cotton close to the second guide cylinder 24 forms a plurality of evenly distributed concave holes pressed by the third molding part 223.

[0044] In summary, through the cooperation between the first guide cylinder 23 and the first conveying roller 25, the cooperation between the first guide cylinder 23 and the second guide cylinder 24, and the cooperation between the second guide cylinder 24 and the second conveying roller 26, multiple groups of sound-absorbing cottons are simultaneously grouted through multiple first moldings 213, second moldings 214, third moldings 223 and fourth moldings 224 to enhance the sound absorption effect of the sound-absorbing cottons, and the sound-absorbing cottons with grouted holes are stacked by glue to further enhance the sound absorption effect of the sound-absorbing cottons.

[0045] Embodiment 2 In actual use, it was found that although multiple recessed holes and multiple layers of sound-absorbing cotton with recessed holes were stacked, it was found that a lot of residual glue appeared in the recessed holes during the stacking and pressing process, resulting in too much glue occupying the recessed holes, resulting in low sound absorption and sound reduction efficiency of the stacked sound-absorbing cotton, and there was also a phenomenon of local loose adhesion between the sound-absorbing cotton layers. For this reason, further improvements were made on the basis of the above embodiments.

[0046] When used based on the above embodiment, the sound-absorbing cotton located between the first conveying roller 25 and the first guide cylinder 23, the first guide cylinder 23 and the second guide cylinder 24, and the second guide cylinder 24 and the second conveying roller 26 is synchronously conveyed to between the two composite parts 32 for compounding.

[0047] Specifically, the motor drives one of the composite parts 32 to rotate counterclockwise and the other composite part 32 to rotate clockwise to cooperate with each other, so that the sound-absorbing cotton is continuously transported away from the first guide cylinder 23 and the second guide cylinder 24. While the composite part 32 rotates, the multiple bosses 33 cooperate with each other to transport the multiple layers of sound-absorbing cotton located between the two composite parts 32.

[0048] Debugging is performed before use. When the composite parts 32 rotate in cooperation with each other, under the expansion action of the third elastic part 352, one end of the multiple movable parts 35 extending out of the compression chamber 323 contacts the outer wall of the guide part 311. When the third elastic part 352 expands, the movable parts 35 slide in the compression chamber 323. Since the fifth elastic part 37 is in a expanded state, the sealing ring 36 contacts the retaining ring in the storage chamber 322, and the storage chamber 322 and the compression chamber 323 are not connected. When the movable parts 35 gradually separate from the guide part 311 and continuously move toward the fixed rod 31 under the expansion action of the third elastic part 352, negative pressure is generated in the compression chamber 323, and the glue liquid in the glue storage box 101 enters the connecting part 102 through the pipeline and the one-way valve. The liquid enters the compression chamber 323 through the delivery hole 324. As the composite member 32 continues to rotate, multiple movable members 35 alternately contact the outer wall of the fixed rod 31 through the rotation of the composite member 32. When one of the movable members 35 rotates with the composite member 32 and moves to a position adjacent to the guide member 311, as the composite member 32 continues to rotate, the movable member 35 contacts the guide member 311. Under the rotation of the composite member 32, the movable member 35 adjacent to the guide member 311 gradually contacts the outer surface of the guide member 311. While the movable member 35 contacts the guide member 311, it continuously moves away from the fixed rod 31. While the movable member 35 slides on the outer wall of the guide member 311 and continuously moves away from the fixed rod 31, the movable member 35 slides in the compression chamber 323 and continuously squeezes the third elastic member 352.

[0049] When the movable part 35 moves in the compression chamber 323, it drives the guide part 351 to move synchronously. When the guide part 351 moves, it drives the dispensing part 34 to move in the sliding hole 321, and continuously extends the boss 33 to contact the sound-absorbing cotton to assist in the transportation of the sound-absorbing cotton. Similarly, under the relaxation effect of the fourth elastic part 356, the limit ring 355 is always in contact with the inner wall of the limit groove 354. At this time, the outer wall of the connecting rod 357 cooperates with the sealing ring 342, so that the glue cannot flow out through the guide groove 3571 and the through hole 341 opened by the dispensing part 34.

[0050] While the third elastic member 352 is compressed, since a one-way valve is provided in the pipeline between the glue storage box 101 and the connecting member 102, the glue liquid in the compression chamber 323 is continuously squeezed as the movable member 35 moves downward. While the glue liquid in the compression chamber 323 is squeezed by the movable member 35, as the pressure of the glue liquid in the compression chamber 323 increases, as the movable member 35 moves downward, the glue liquid is pressurized and continuously squeezes the sealing ring 36. The sealing ring 36 moves downward under the action of the high-pressure glue liquid and continuously squeezes the fifth elastic member 37. While the fifth elastic member 37 is compressed, the high-pressure glue liquid in the compression chamber 323 enters the storage chamber 322 for pressure storage.

[0051] When the movable part 35 moves to the farthest position from the fixed rod 31, the pressing head 312 enters the movable part 35 and presses the guide rod 353. At the same time, the dispensing part 34 extends the farthest from the boss 33. At the same time, one end of the dispensing part 34 extending from the boss 33 passes through the sound-absorbing cotton pressed by the first conveying roller 25 and the first guide cylinder 23, and contacts the surface of the sound-absorbing cotton pressed by the first guide cylinder 23 and the second guide cylinder 24. At the same time, due to the pressure on the guide rod 353, the guide rod 353 is in the movable part 35. The guide rod 353 moves in the inner cavity, and the limiting ring 355 moves in the limiting groove 354. The limiting ring 355 squeezes the fourth elastic member 356 while moving. The guide rod 353 moves so that the guide ring 3531 is connected with the guide hole 3511. At this time, the high-pressure glue in the compression chamber 323 and the storage chamber 322 enters the inner cavity of the guide member 351 through the multiple holes 3532. At the same time, the fifth elastic member 37 expands and squeezes the sealing ring 36, thereby squeezing the storage chamber 322 and the compression chamber 323. At the same time, the high-pressure glue in the inner cavity of the guide member 351 enters the through hole 341 opened in the dispensing member 34, and the high-pressure glue in the dispensing member 34 further flows into the through hole 341 through the guide groove 3571 opened by the connecting rod 357. When the guide groove 3571 is connected to the through hole 341, one end of the connecting rod 357 extending out of the dispensing member 34 contacts and presses the surface of the sound-absorbing cotton pressed by the first guide cylinder 23 and the second guide cylinder 24, and the glue passes through the through hole 341 opened in the dispensing member 34. The glue flows out from the gap between the hole 341 and the connecting rod 357 and is injected into the pressing part of the connecting rod 357, so that when the glue dispensing part 34 gradually separates from the surface of the sound-absorbing cotton pressed by the first guide cylinder 23 and the second guide cylinder 24, the glue remains in the recess pressed by the connecting rod 357 to prevent the glue from overflowing and filling the recess. At the same time, the multiple layers of sound-absorbing cotton are extruded and compounded by multiple bosses 33, and the glue is sprayed at fixed points around the pressed recess, completing the precise pressing of the multiple layers of sound-absorbing cotton, thereby ensuring that the multiple layers of sound-absorbing cotton are evenly adhered and effectively compounded.

[0052] In summary, the two relatively arranged composite members 32 continuously rotate in coordination, and the third elastic member 352 is expanded, so that the movable member 35 slides in the compression chamber 323 and contacts the fixed rod 31. At the same time, the movable member 35 sucks the compression chamber 323 to generate negative pressure in the compression chamber 323, so that the glue liquid in the glue storage box 101 enters the connecting member 102 through the pipeline and the one-way valve, and the glue liquid in the connecting member 102 enters the compression chamber 323 through the delivery hole 324, and the glue liquid in the compression chamber 323 is replenished, thereby ensuring that there is a continuous quantitative replenishment of glue when the multi-layer sound-absorbing cotton is composited; Under the action of continuous rotation, one of the movable parts 35 rotates with the composite part 32 and moves to a position adjacent to the guide part 311. As the composite part 32 continues to rotate, the movable part 35 contacts the guide part 311. The movable part 35 slides on the outer wall of the guide part 311 and continuously moves away from the fixed rod 31. At the same time, the movable part 35 slides in the compression chamber 323 and continuously squeezes the third elastic part 352. When the glue liquid in the compression chamber 323 is squeezed by the movable part 35, as the pressure of the glue liquid in the compression chamber 323 increases, as the movable part 35 moves downward, the glue liquid is pressurized and continuously squeezes the sealing ring 36. The sealing ring 36 is pressed by the high-pressure glue. The fifth elastic member 37 is moved downward under the action of the liquid and continuously squeezes the fifth elastic member 37. When the fifth elastic member 37 is compressed, the high-pressure glue liquid in the compression chamber 323 enters the storage chamber 322 for pressure storage, thereby ensuring that the pressure is sufficient each time the glue is dispensed; when the movable member 35 moves to the farthest position from the fixed rod 31, the pressing head 312 enters the movable member 35 and presses the guide rod 353. At the same time, the glue dispensing member 34 extends the farthest distance from the boss 33. At the same time, one end of the glue dispensing member 34 extending from the boss 33 passes through the sound-absorbing cotton pressed by the first conveying roller 25 and the first guide cylinder 23. The high-pressure glue liquid in the glue dispensing member 34 passes through the opening of the connecting rod 357. The guide groove 3571 further flows into the through hole 341. Because, when the guide groove 3571 is connected with the through hole 341, one end of the connecting rod 357 extending out of the glue dispensing part 34 contacts and presses the surface of the sound-absorbing cotton pressed by the first guide cylinder 23 and the second guide cylinder 24, and the glue flows out through the through hole 341 opened by the glue dispensing part 34 and the gap between the connecting rod 357, so that the multi-layer sound-absorbing cotton is pressed while the fixed-point and quantitative glue spraying is performed around the pressed concave cavity, ensuring that the multi-layer sound-absorbing cotton is evenly adhered, and at the same time, a closed chamber is formed between the concave cavity of the multi-layer sound-absorbing cotton, and sound absorption is performed through multiple closed chambers, thereby enhancing the sound absorption and silencing effects.

[0053] Embodiment 3 Based on the above embodiments, it is found that although the two adjacent sound-absorbing cottons are bonded together by compounding multiple layers of sound-absorbing cotton, so that the chamber formed by the two recesses of the sound-absorbing cotton can effectively absorb and silence sound, there is still a problem of misalignment of the recesses due to the elastic deformation of the sound-absorbing cotton during transportation.

[0054] When used on the basis of the above embodiment, the sound-absorbing cotton between the first guide cylinder 23 and the first conveying roller 25 is conveyed to the composite component 3 for compounding through the first adjusting roller 41. At the same time, the sound-absorbing cotton between the second guide cylinder 24 and the second conveying roller 26 is conveyed to the composite component 3 for compounding through the second adjusting roller 42. When the multi-layer sound-absorbing cotton after compounding by the composite component 3 has misaligned concave holes, it is only necessary to change the speed of the driving motor of the first adjusting roller 41 and the second adjusting roller 42 to make fine adjustments to the conveying speed of the sound-absorbing cotton between the first guide cylinder 23 and the first conveying roller 25 or the sound-absorbing cotton between the second guide cylinder 24 and the second conveying roller 26, thereby ensuring that the multi-layer sound-absorbing cotton does not cause misalignment of the concave holes when compounding.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
