Description

Technical Field

[0001] The utility model relates to the field of automobile sound insulation cotton, in particular to a raw material mixing device for producing automobile sound insulation cotton. Background Art

[0002] The car sound-absorbing cotton can absorb the noise generated during the driving of the vehicle through the fine fibers inside the sound-absorbing cotton, which eventually leads to heat energy and disappears. It can achieve the function of sound absorption and noise reduction. As an important evaluation index of car riding comfort, car noise will also reflect the design level and process level of the manufacturer to a large extent. Therefore, controlling car noise at an appropriate level is also the direction pursued by car designers. In the production of car sound insulation cotton, multiple raw materials need to be mixed.

[0003] A raw material mixing device for the production of automobile sound insulation cotton, with a Chinese authorized announcement number of CN214287820U, is provided with a feeding hopper on the upper inner wall of the device body. After the raw materials enter the feeding hopper through the feeding hopper, the mounting rod is driven by the first rotating shaft to rotate and drive the scraper plate to scrape in the feeding hopper, so that the raw materials can enter the interior of the device body evenly from the feeding hopper, avoiding uneven mixing caused by the raw materials entering the device body through the same position, improving the efficiency of the device in mixing raw materials, and solving the problem that the raw materials cannot be evenly added to the interior of the device body when the existing device is used.

[0004] There are still some shortcomings when using it:

[0005] There will inevitably be impurities on the surface of the raw materials. Before the raw materials are mixed, the large particles of impurities on the surface of the raw materials cannot be removed, thereby reducing the cleanliness of the raw materials during mixing and reducing the mixing effect of the raw materials. At the same time, when the raw materials are mixed, the raw materials on the inner wall of the device body cannot be mixed, and there will be a dead angle for the mixing of the raw materials, resulting in poor mixing quality of the raw materials;

[0006] When the raw materials are mixed and discharged, the raw materials may clog the discharge pipe, reducing the discharge rate of the raw materials, making the practicality and convenience of the mixing device poor. At the same time, when the raw materials cannot be discharged quickly, it will also affect the normal use of the mixing device next time.

[0007] Therefore, in view of the above problems, a raw material mixing device for producing automobile sound insulation cotton is proposed. Utility Model Content
