Description
Technical Field
[0001] The present application relates to the field of sound-absorbing cotton production, and in particular to a sound-absorbing cotton heat-cutting and edge-sealing device for automobile doors. Background Art
[0002] With the development of automobile technology, vehicles are becoming faster and faster. At the same time, people are paying more and more attention to the driving experience. As vehicle speeds increase, wind noise generated by the vehicle gradually becomes the main source of noise. Prolonged exposure to noisy environments can cause driver fatigue and irritation, posing a hidden danger to driving safety.
[0003] To reduce interior noise, vehicles are designed with streamlined exteriors, while also strengthening the vehicle structure to reduce vibration and, consequently, reduce interior noise. Door panels are key structural components of the door interior, covering the sheet metal, enhancing the interior environment, and securing the door's functional components. In modern vehicles, to enhance the sound insulation and absorption capabilities of door panels, a layer of lightweight, porous sound-absorbing cotton is often placed between the door panels and the sheet metal.
[0004] Sound-absorbing cotton is a material with sound-absorbing function, which can effectively absorb sound waves and reduce the reflection and propagation of sound to reduce noise and improve the sound environment.
[0005] In the production of sound-absorbing cotton, the sound-absorbing cotton must first be moved to the cutting equipment for cutting; after the cutting is completed, the cut sound-absorbing cotton must be moved to the edge sealing equipment for edge sealing, thereby completing the processing.
[0006] However, the entire processing step is relatively cumbersome and requires continuous handling of the sound-absorbing cotton, which affects the processing efficiency of the sound-absorbing cotton. Utility Model Content

Generally, a heating system is provided inside the hot press processing table 12. The hot press processing table 12 can heat the sound-absorbing cotton, thereby facilitating the edge-seal of the sound-absorbing cotton and improving the edge-seal quality.
[0041] See also Figure 1 and Figure 2A processing component is provided on the workbench 1, which has two functions of die-cutting and edge-sealing the sound-absorbing cotton, so there is no need to constantly carry the sound-absorbing cotton, which simplifies the operation steps and improves the processing efficiency of the sound-absorbing cotton.
[0042] See also Figure 3 and Figure 4 The processing components include: a driving part 2, a die-cutting part 3 and an edge-sealing part 4.
[0043] See also Figure 4 The drive unit 2 includes a lifting seat 21 and two lifting hydraulic cylinders 22. The lifting hydraulic cylinders 22 are fixedly mounted on the work frame 1 and are located at both ends of the work frame 1 along the width direction. The lifting seat 21 is fixedly mounted between the output shafts of the two lifting hydraulic cylinders 22 and is located directly above the processing table 12. During processing, the lifting hydraulic cylinders 22 are activated to drive the lifting seat 21 downward, thereby facilitating the die-cutting unit 3 and the edge-sealing unit 4 to perform die-cutting and edge-sealing on the sound-absorbing cotton.
[0044] See also Figure 4 The die-cutting part 3 includes: an external die-cutting knife 31, an external pressure spring 32, an internal die-cutting knife 33 and an internal pressure spring 34. The bottom wall of the lifting seat 21 is provided with a mounting groove 211. One end of the external pressure spring 32 is fixed to the bottom of the mounting groove 211, and the other end is fixed to the top wall of the external die-cutting knife 31. The external pressure spring 32 can press down the external die-cutting knife 31, so that the external die-cutting knife 31 die-cuts the sound-absorbing cotton to form the outer ring contour.
[0045] See also Figure 4 One end of the internal pressure spring 34 is fixed to the bottom of the mounting groove 211, and the other end is fixed to the top wall of the internal die cutter 33. The internal pressure spring 34 can press down the external internal die cutter 33, so that the internal die cutter 33 die-cuts the sound-absorbing cotton to form the inner ring contour, thereby obtaining the required shape of the sound-absorbing cotton.
[0046] During processing, the lifting hydraulic cylinder 22 is started to drive the lifting seat 21 to move downward until the outer die cutter 31 and the inner die cutter 33 contact the sound-absorbing cotton; then, the lifting seat 21 is continued to be pushed downward. At this time, the external pressure spring 32 and the internal pressure spring 34 will be compressed, thereby pressing the outer die cutter 31 and the inner die cutter 33 to die-cut the sound-absorbing cotton.

[0052] See also Figure 5 、 Figure 6 and Figure 7 The difference between this embodiment and the first embodiment is that a downward blowing component 6 for blowing air to the sound-absorbing cotton is provided on the base plate 43. After the sound-absorbing cotton is sealed, the downward blowing component 6 is started to blow the sound-absorbing cotton, thereby facilitating the separation of the sound-absorbing cotton from the outer edge sealing block 41 and the inner edge sealing block 42, so that manual separation is not required.
[0053] See also Figure 7The down-blowing assembly 6 includes a rotating rod 61, a fan blade 62, and a drive motor 63. The rotating rod 61 is vertically rotatably mounted on the base plate 43, and the fan blade 62 is fixed to the rotating rod 61. The drive motor 63 is mounted on the base plate 43, and the output shaft of the drive motor 63 is coaxially fixed with the rotating rod 61. After the sound-absorbing cotton is edge-sealed, the drive motor 63 is started to drive the rotating rod 61 to rotate the fan blade 62, thereby blowing the sound-absorbing cotton.
