Description

Technical Field

[0001] This utility model relates to the technical field of automotive sound-absorbing cotton processing equipment, and in particular to a thermal cutting device for forming automotive sound-absorbing cotton. Background Technology

[0002] Automotive sound-absorbing cotton is made of various materials through thermal spraying and melting. Its structure consists of extremely fine, long tubular fibers, featuring high sound absorption coefficient, flame retardancy, extremely low water absorption, mold resistance, and being non-toxic, odorless, and dust-free. This new material is currently widely used by many vehicle manufacturers to absorb and reduce noise generated by the engine and vehicle operation. When ambient noise and vehicle vibration noise enter the sound-absorbing cotton, the noise energy is dissipated through friction with the air within the numerous extremely fine tubular fibers. Ultimately, the noise energy entering the vehicle is greatly reduced. This reduced noise can then be absorbed by the sound-absorbing cotton, reducing reflection. After installation, the quieter sound effect after sound absorption and noise reduction is clearly noticeable.

[0003] However, when using the existing thermal cutting device for forming sound-absorbing cotton, the sound-absorbing cotton needs to be removed and a new sound-absorbing cotton needs to be installed after thermal cutting. This removal and placement process consumes a lot of time, resulting in low processing efficiency. Utility Model Content

A worm wheel 4 is connected to the lower end of the base plate 1. A rotating plate 5 is fixedly connected to the upper end of the worm wheel 4. The first motor 2, worm gear 3, worm wheel 4, and rotating plate 5 drive the electric heating wire 15 to rotate. After one automotive sound-absorbing cotton is thermally cut, another automotive sound-absorbing cotton can be thermally cut, saving pick-up and drop-off time. A column 6 is fixedly connected to the upper end of the rotating plate 5. An installation groove 7 is opened inside the column 6. A second motor 8 is fixedly connected inside the installation groove 7. A threaded rod 9 is fixedly connected to the output shaft of the second motor 8. A threaded block 10 is threadedly connected to the outer surface of the threaded rod 9. An installation rod 12 is fixedly connected to one side of the threaded block 10. By setting up the column 6, the second motor 8, the threaded rod 9, and the threaded block 10, the electric heating wire 15 is driven to descend, thereby facilitating the thermal cutting of automotive sound-absorbing cotton.

[0023] A connecting rod 13 is fixedly connected to the lower end of the mounting rod 12, and a mounting frame 14 is fixedly connected to the lower end of the connecting rod 13.

[0025] Working principle: This thermal cutting device for molding automotive sound-absorbing cotton works by connecting the power supply, placing the automotive sound-absorbing cotton on a worktable 16, and starting the electric push rod 18. The electric push rod 18 drives the fixing plate 19 to descend, squeezing and fixing the automotive sound-absorbing cotton. The second motor 8 is then started, driving the threaded rod 9 to rotate. The threaded rod 9 drives the threaded block 10 to move, which in turn drives the mounting rod 12, connecting rod 13, and mounting frame 14 to descend, thereby causing the electric heating wire 15 to descend. The electric heating wire 15 then applies pressure to the automotive sound-absorbing cotton.
