[0026] Sound-absorbing cotton is a crucial component of automotive noise reduction and muffler components. It is a man-made inorganic fiber made from natural minerals such as quartz sand, limestone, and dolomite. It is melted into glass with chemical raw materials such as soda ash and borax. Once molten, it is blown into fine, flocculent fibers with the help of an external force. The fibers intersect and entangle with each other, creating numerous tiny gaps. During the production process, automotive sound-absorbing cotton requires drying.

[0027] In the related art, the automobile sound-absorbing cotton processing and drying device generates harmful exhaust gas when the sound-absorbing cotton is dried. If the exhaust gas is not treated and is directly discharged into the air, it will pollute the air.

[0028] Based on this, in order to improve the problem that the waste generated when the device in the related art dries the sound-absorbing cotton will cause pollution to the surrounding environment, the embodiment of the present application provides the following solution.

[0030] Please also refer to Figures 1 to 5 The heating mechanism includes a heating tube 21 and a first fan 22. There are multiple heating tubes 21. The heating tubes 21 are arranged inside the frame 1. The first fan 22 is arranged at the bottom of the frame 1. The frame 1 is provided with a feed port 11, a discharge port 12 and a vent 13. The frame 1 is rotatably connected to multiple conveying rollers 14. The frame 1 is also rotatably connected to a limiting roller 6. The purification mechanism includes an air suction hood 31, a connecting pipe 32, a fixing ring 33, a connecting head 34, a filter element 35, a filter element sleeve 36 and a vacuum pump. The air pump 37 is provided with a second fan 5 inside the vent 13, the air suction cover 31 is provided on the top of the frame 1, and the air suction cover 31 is connected to the inside of the frame 1 through the vent 13. The filter sleeve 36 and the vacuum pump 37 are both provided on the frame 1, and a sealing gasket 362 is provided on the top of the filter sleeve 36. The filter 35 is provided inside the filter sleeve 36, and the outer peripheral surface of the filter sleeve 36 is provided with a thread. The connector 34 is provided with an air inlet pipe 341, and the fixing ring 33 is sleeved on the connector 34 and is connected to the connector. The outer surface of the head 34 is rotatably connected, the inner circumference of the fixing ring 33 is provided with a thread, the fixing ring 33 is threadedly connected to the filter sleeve 36, the connecting head 34 is in contact with the sealing gasket 362, the air inlet pipe 341 is connected to the air outlet end of the suction cover 31 through the connecting pipe 32, the filter sleeve 36 is also provided with an air outlet pipe 361, the air outlet pipe 361 is connected to the air inlet end of the vacuum pump 37, the winding mechanism includes a winding roller 41 and a power component, the frame 1 is also provided with a mounting port 15, and both ends of the winding roller 41 are connected. They are all rotatably connected to the frame 1 through the mounting port 15. The power assembly includes a motor 421, a first gear 422, a second gear 423 and a transmission shaft 424. The transmission shaft 424 is rotatably connected to the frame 1. The first gear 422 is mounted on one end of the winding roller 41 close to the motor 421. The second gear 423 is mounted on the transmission shaft 424. The first gear 422 and the second gear 423 are engaged for transmission. The output shaft of the motor 421 and the transmission shaft 424 are connected through a belt and a pulley.

[0031] From the above, it can be seen that the sound-absorbing cotton processing and drying device provided in the embodiment of the present application, before the device works, the staff can feed the sound-absorbing cotton from the feed port 11 and take it out from the discharge port 12, the conveying roller 14 will hold up the sound-absorbing cotton, and then pass the sound-absorbing cotton from under the limiting roller 6 and fix it on the winding roller 41, and then turn on the heating mechanism and the purification mechanism, the electric heating tube 21 starts to heat the air around it, the first fan 22 blades rotate and blow air into the frame 1, the first fan 22 blows the hot air around the electric heating tube 21 to the surface of the sound-absorbing cotton and gradually dries the sound-absorbing cotton. The sound-absorbing cotton will produce harmful exhaust gas when it is dried, and these exhaust gases will spread into the inside of the frame 1, and the second fan 5 will exhaust the exhaust gas inside the frame 1 through the suction hood and the connection The exhaust gas is blown into the connector 34 through the pipe 32, and the vacuum pump 37 absorbs the exhaust gas inside the connector 34 through the exhaust pipe 361, so that the exhaust gas passes through the filter element 35. When the exhaust gas passes through the filter element 35, the filter element 35 will filter out the harmful substances inside the exhaust gas. The exhaust gas filtered by the filter element 35 is then discharged into the air outside the device through the exhaust pipe 361, which can reduce the pollution to the surrounding air caused by the device when it is working; after a period of time, the sound-absorbing cotton inside the frame 1 is dried, and the staff can turn on the motor 421. The output shaft of the motor 421 drives the transmission shaft 424 to rotate, and the transmission shaft 424 drives the winding roller 41 to rotate through the first gear 422 and the second gear 423, and the winding roller 41 will roll the sound-absorbing cotton roll that has been dried. The sound-absorbing cotton is continuously dried inside the frame 1 under the drive of the winding roller 41. The conveying roller 14 will rotate under the action of the friction between the conveying roller 14 and the sound-absorbing cotton, which plays a role in supporting the sound-absorbing cotton and reducing the friction between the sound-absorbing cotton and the frame 1. The limiting roller 6 can limit the sound-absorbing cotton to avoid friction between the sound-absorbing cotton and the edge of the discharge port 12. In this way, the automatic drying and rolling of the sound-absorbing cotton can be completed. When the sound-absorbing cotton rolled up on the winding roller 41 reaches a certain mass, the staff can temporarily shut down the device and cut the sound-absorbing cotton, then remove the winding roller 41 from the installation port 15, and remove the rolled sound-absorbing cotton for subsequent operations. After removing the sound-absorbing cotton, the staff can put the winding roller 41 back to the installation port 15, and make the first gear 422 mesh with the second gear 423, and then the next round of work can be started; after the device has been working for a long time, the filter element 35 will absorb too much harmful substances, resulting in reduced filtering effect. At this time, the staff can twist the connector 34 to disengage the connector 34 from the filter element sleeve 36, and then take the filter element 35 out of the filter element sleeve 36 and put in a new filter element 35, and then screw the connector 34 back onto the filter element sleeve 36. The filter element 35 will seal the opening connecting the outlet pipe 361 with the inside of the connector 34, so that the exhaust gas will be filtered through the filter element 35 when entering the connector 34. The connector 34 will press the sealing gasket 362 against the filter element sleeve 36 to form a seal to prevent leakage of exhaust gas.

[0032] In some embodiments, please refer to Figure 1 and Figure 3 The frame 1 has an air curtain machine 7 on both the side where the feed port 11 is opened and the side where the discharge port 12 is opened.

[0033] With such an arrangement, since the feed port 11 and the discharge port 12 cannot be sealed, some exhaust gas will leak to the outside of the device through the feed port 11 or the discharge port 12. The air curtain machine 7 will form an air curtain at the feed port 11 and the discharge port 12 to reduce the exhaust gas leakage from the feed port 11 and the discharge port 12.

[0034] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
