Detailed Description

As shown in fig. 1-4, a noise reduction device of a heating sheet filling device comprises a sound-proof cover 2 arranged on a connecting rod 1, wherein a vibrator 3 for blanking is covered inside the sound-proof cover 2; the sound-proof housing 2 comprises a body 21 fixed on the connecting rod 1 and a housing door 22 installed on the body, a first vacuum cavity 211 and/or a solid resonant cavity 212 are/is arranged in the cavity wall of the body 21, the first vacuum cavity 211 is vacuumized, noise generated by the vibrator 3 can be isolated from the outside, and the solid resonant cavity 212 is filled with fine sand, so that the sound-proof effect is further improved.

The inner surface of the body 21 is provided with a plurality of sound-deadening protrusions 213, and the sound-deadening protrusions 213 increase the inner surface area of the body 21, increase the propagation path of the noise generated from the vibrator 3 in the body 21, and thus attenuate the sound volume. The horizontal cross-section of the first vacuum chamber 211 and the horizontal cross-section of the solid resonant cavity 212 are curved.

Specifically, be equipped with the perspective window 221 that is used for observing vibrator 3 on the cover door 22, cover door 22 is articulated with body 21, makes things convenient for switch cover door 22 to overhaul vibrator 3. The transparent window 221 is composed of two layers of transparent shockproof glass, and a second vacuum cavity is arranged between the two layers of transparent shockproof glass.
