Description
Affiliated technical field
The utility model relates to a kind of sound absorption and sound insulating structure of soundproof door, specifically, is primarily aimed at the noise control of industry, especially a kind of effect that is used for cigarette factory's cigarette machine equipment reduction noise.Belong to tobacco corollary equipment field.
Background technology
Cigarette industry has been realized large-scale automation at present, noise abatement problem with regard to factory has been an instant problem at present, through commercial measurement, the average noise sound pressure level of inside, workshop has surpassed 85dB (A), not only influenced production to a certain extent, the physical and mental health that more seriously endangers the employee.
Because the driving and the transmission mechanism of unit inside are many, forms of motion is also very complicated simultaneously, and various single noises and reverberation are mingled together, and influence to external world is very big.Original body of unit rear side can intercept partial noise.But because the structure of unit door body is thorough inadequately to the consideration of acoustics noise reduction, so the sound insulation and noise reducing effect of unit rear door body and not obvious.
Unit door body and doorframe adopt every, that sound absorption material is selected for use is improper, simultaneously a lot of materials since service time long, serious aging, the DeGrain of sound insulation, sound absorption.
In order to solve noise problem, reduce noise to greatest extent, the machine in workshop has been done a large amount of investigation and research work, series of effective noise reduction scheme has been proposed.After transforming, the noise in workshop reduces gradually, becomes an environment that comparatively is fit to employee work.In such environment, the workman just can not produce the mood of being sick of to work because of being exposed to for a long time under the very noisy, and employee's enthusiasm will be surging, and the enthusiasm of work also can strengthen, and then has improved operating efficiency.
The utility model content
The utility model purpose is to overcome the defective of background technology, invents a kind of sound absorption and sound insulating structure of the soundproof door by technological improvement, it its simple in structure, easily install, long service life, outward appearance is neat and artistic, can provide good, thereby satisfy the defective of background technology every, sound absorbing capabilities.
For addressing the above problem, the sound absorption of the utility model soundproof door and the technical scheme that sound insulating structure adopted are: soundproof door is by hinge (1), hinge axis (2), door body (3,7), panel (10), lock (6), doorframe (4), interior doorframe (18), vertical beam (14), side support (16) and handle (5) are formed, it is characterized in that panel (10) employing is followed successively by steel plate from outside to inside, sound-insulating felt, steel plate, foamed aluminium and perforated plate (15) structure, damping rubber plate (11) is attached on the panel (10), refill sound absorption material (12), with damping rubber plate (11) adorn/be bonded at panel (10) is gone up or doorframe (4) on, elastic film (13) is posted at the last formation door of perforated plate (a 15) body (3,7), by spot welding with door body (3,7) be connected with door inside casing (18), load onto weather strip at last.
Hinge is a rectangular-shaped cuboid, has a connecting hole on one of them plane, has the special hinge of three connecting holes on another plane, and hinge is installed on the hinge seat (19), and hinge seat (19) is welded on a body (3,7) inside.
Perforated plate (15) is cavernous.
Door body (3,7) adopts exterior buckle type to be connected with doorframe (4).
The utility model is taked such scheme, has the following advantages:
1. structure in the past is to adopt Embedded installation, has brought inconvenience to installation, after long-time the use, causes a body deformability easily, causes poor sealing, the DeGrain of noise reduction.And present structure satisfies above-mentioned defective.Adopt exterior buckle type (as accompanying drawing 1).
2. because of door body inboard the sound absorption and insulation material is housed all, so the weight of door body is all very heavy.If it is not enough that the selected hinge strength of door body is installed, after long-time the use, cause a body deformability easily, influence sealing effectiveness.At this situation, the hinge of employing is special hinge (Fig. 4), and the moment of bearing is big, the reliability height.Be well suited for exterior buckle type door body and install, guarantee door body sealing effectiveness, reach the noise reduction purpose.
3. adopt damping rubber plate (11), sound absorption material (12), elastic film (13), perforated plate (15) to reach the effect of noise reduction, at the cigarette machine equipment of factory during in operation, vibration, noise etc. are arranged, above-mentioned damping rubber plate (11), sound absorption material (12), elastic film (13), perforated plate (15) common combination reach the reduction anti noise, Fig. 2 middle punch plate (15) is cavernous, the effect of existing absorption sound wave.

The specific embodiment:
Embodiment 1: because of the structure composition of door body is identical, is example with the left-hand door below, the sound insulating structure composition is described, specific as follows:
The utility model sound insulating structure, its structure is formed: left-hand door panel 10, damping rubber plate 11, interior doorframe 18, vertical beam (14), side support 16, sound absorption material 12, elastic film 13, perforated plate 15.
As accompanying drawing 1 sound insulating structure, its composition is made of hinge 1, hinge axis 2, door body 7, lock 6, doorframe 4, handle 5, and is simple in structure, easily install, and long service life, outward appearance is neat and artistic.Main is to reach the reduction anti noise.
The sound absorption of soundproof door and sound insulating structure, adopt five layers of design principle, be followed successively by from outside to inside: the steel plate that 2mm is thick, the sound-insulating felt that 2mm is thick, the steel plate that 1mm is thick, the foamed aluminium that 30mm is thick, the perforated plate that 1mm is thick, the design of multi-layer door body structure is widely used in various noise reduction occasions, each layer all has sound insulation or sound absorption, sound can reduce, to improve noise reduction through this door body of five layers.As shown in Figure 5.
The sound absorption of soundproof door, it is primarily aimed at: sound absorption material 12 provides the material that a kind of effective isolation sound is relayed, be high-tech novel sound absorption, sound insulating material, have goodly,, can reach well every, acoustically effective through Acoustical Inst., Chinese Academy of Sciences's check every, sound absorbing capabilities.
Sound insulating structure is a substrate with panel 10, and hinge seat 19, door inside casing 19, vertical beam 14 and side support 16 are welded on the panel, welds, and carries out sandblast, sprays paint.The good back of spray is being attached to damping rubber plate (11) on the panel 10 with glue, again lock 6 and handle 5 are installed, load onto sound absorption material 12, the elastic film 13 that posts on perforated plate 15 is being installed, being connected with door inside casing 18, load onto weather strip (Fig. 6) at last by spot welding.
Weather strip, weather strip all are the installation forms of selecting for use from clamping.On the steel plate of door body, when the door body was closed, the sealing of weather strip needed a door body 3 to weather strip by its toothholder that clamps certainly, 7 and 4 pairs of weather strips of doorframe apply a power, allow weather strip that a decrement is arranged, thereby reach the effect of sealing, and then realize the purpose of noise reduction.The power that weather strip is applied realizes by lock 6 is installed on door.After door is shut, snap on the doorframe 4 by lock core, door can not be opened, simultaneously, this lock also applies a power to weather strip, allows weather strip compress, and then realizes the effect of sealing.In order to allow weather strip compress, two locks are installed on the per pass door, can guarantee the effect of sealing like this.
Sound insulating structure, being welded in the body of its hinge seat 19 is connected (as accompanying drawing 1) by the staking nut when doorframe hinge 1 is installed with hexagon socket head cap screw, and hinge 1 is connected (as accompanying drawing 1) with hinge seat 19 by hinge axis.
The maximum compressibility of weather strip is 5mm.
