Embodiment Construction
[0039] Below in conjunction with accompanying drawing, the present invention is described in detail as follows:
[0040] exist figure 1 neutralize figure 2 Among them, the noise reduction device of this coiling unit is to install a muffler and a sound absorbing body on the coiling unit. The coiling unit is composed of a feeding strip machine, a coil forming machine and a splicing machine from right to left. , the crimping unit has two fans in total, one is installed on the feeding machine, which plays the role of shredded tobacco conveying and dust removal, and the other is installed on the tipping machine, which generates working negative pressure and plays the role of dust removal. An eccentric pipe muffler 1 is installed in the installation room 8 of the air outlet of the dedusting fan. Install multi-layer plexiglass doors 4 on the observation protective windows of the splicing machine, install door sound-absorbing structures 2 on all protective doors of the coiling uni...

The invention relates to a noise reduction method for a cigarette making and tipping unit; aiming at air power noise, mechanical transmission and resonance noise and electromagnetic excitation noise, the noise reduction method is characterized in that a vibration reduction and noise reduction device is independently designed according to different noise frequencies and vibration strength characteristics, so that the purpose of reducing the total noise of the cigarette making and tipping unit is achieved; the noise reduction device for the cigarette making and tipping unit is characterized in that an eccentric pipeline silencer is installed in an installation room of the air outlet of a negative-pressure dust-removing fan of a plug assembler; the installation room is provided with a protective door; a bent pipe silencer is installed at the elbow of the air inlet of a negative-pressure fan of a feeder; a plurality of layers of organic glass doors are installed on an observation protective window of the plug assembler; door sound absorption structures are installed on all protective doors of the cigarette making and tipping unit; noise reduction sealing is additionally arranged on housings and doors, unnecessary to frequently open, on the cigarette making and tipping unit; and a shock absorption cushion is installed on a motor installation base. The noise reduction method for the cigarette making and tipping unit and the noise reduction device thereof disclosed by the invention have the benefits that: by means of individualized design and noise reduction improvement, all noise detection points of the cigarette making and tipping unit are less than 85 dB.
Description
technical field [0001] The invention relates to a cigarette machine, especially a method and device for reducing noise of a crimping unit, specifically to realize vibration reduction and noise reduction of a high-speed crimping unit in a stable operating state, so as to meet the requirements of environmental protection and green production. Background technique [0002] The crimping and splicing unit is an important equipment in the production of cigarette industry, which is mainly composed of a feeding rod forming machine, a coiling forming machine and a splicing and filling machine. During the process of tobacco conveying, loosening, impurity removal, sliver forming, rolling and splicing, the coiling unit runs at high speed, accompanied by high pressure, negative pressure and dust removal process. Because the early design did not consider noise reduction, the noise is too large. The unit is not only noisy, but the noise sources are widely distributed (see Figure 9 ), and ...
