Description
Technical field
A kind of needle punched non-woven fabrics are the utility model is related to, more precisely one kind can lift the insulation of needle punched non-woven fabrics drop sound
The needle punched non-woven fabrics of function.
Background technology
Non-woven fabrics, also known as adhesive-bonded fabric, it is to be made up of fiber orient or random, is environment-friendly materials of new generation, because of tool
Have cloth outward appearance and some performances and be called cloth.Existing non-woven fabrics uses single non-woven fabrics base fabric material, sound insulation mostly
Effect and heat insulation effect are poor.
The content of the invention
The purpose of this utility model is to provide a kind of needle punched non-woven fabrics for lifting needle punched non-woven fabrics drop sound heat insulation function, energy
Enough solve the problems, such as above-mentioned.
The utility model to achieve the above object, is achieved through the following technical solutions：
It can lift the needle punched non-woven fabrics of needle punched non-woven fabrics drop sound heat insulation function, including the first base fabric and the second base fabric, first
The bottom of base fabric sets several upper ribbons being arranged in a row, and the top of the second base fabric sets several lower fibers being arranged in a row
Bar, it is square waveform that each lower ribbon has cross section between two upper ribbons, between upper ribbon and lower ribbon
Gap, square waveform inner space filling wood chip layer.
In order to further realize the purpose of this utility model, following technical scheme can also be used:First base fabric and
Pin is set in the second base fabric, and pin sequentially passes through the first base fabric, upper ribbon, wood chip layer, lower ribbon and from up to down
Two base fabrics, the lower end connection wire rod of pin, the sidepiece of screw mandrel set open-work, threaded coupling nut on screw mandrel, between adjacent pin
Connected by strengthen rope, the both ends of strengthen rope both pass through corresponding open-work.
The thickness of the wood chip layer is 3.7 millimeters.
The utility model has the advantage of：The utility model meets base fabric, ribbon and wood chip layer three, makes whole pin
Prick nonwoven cloth product had both possessed higher intensity, while had preferable sound insulation and heat insulation function.Upper fiber of the present utility model
Bar and lower ribbon cooperate, and can improve the tensile strength of the first base fabric and the second base fabric, meanwhile, upper ribbon is with
Ribbon is cooperated, and forms the space that a cross section is square waveform, and wood chip layer can be made to form cross section as square waveform
Ribbon tight can be effectively improved the sound insulation value of needle punched non-woven fabrics, in the feelings of same grammes per square metre by layer structure, wood chip layer
Under condition, reducing effect lifting 65%.By original 70-90 decibels, 20-40 decibels are reduced to.Because wood chip layer is the cross section side of being
The layer structure of waveform, each ribbon is set to form an independent insulation construction under the parcel of wood chip layer, so as to effectively
Improve the sound insulation value of needle punched non-woven fabrics.The utility model also has compact, manufacturing cost simple for structure cheap and using letter
Just the advantages of.
Brief description of the drawings
Accompanying drawing is used for providing further understanding to of the present utility model, and a part for constitution instruction, with this practicality
New embodiment is used to explain the utility model together, does not form to limitation of the present utility model.In the accompanying drawings：

Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
The needle punched non-woven fabrics of needle punched non-woven fabrics drop sound heat insulation function can be lifted, as shown in figure 1, including the first base fabric 1 and
Two base fabrics 3, the bottom of the first base fabric 1 set several upper ribbons 4 being arranged in a row, and the top of the second base fabric 3 sets several rows
Lower ribbon 2 in a row, each lower ribbon 2 is between two upper ribbons 4, between upper ribbon 4 and lower ribbon 2
With the gap that cross section is square waveform, the inner space filling wood chip layer 5 of square waveform.
The utility model meets base fabric, ribbon and wood chip layer three, make whole needle punched non-woven fabrics product both possessed compared with
High intensity, while there is preferable sound insulation and heat insulation function.Upper ribbon 4 of the present utility model and the phase interworking of lower ribbon 2
Close, the tensile strength of the first base fabric 1 and the second base fabric 3 can be improved, meanwhile, upper ribbon 4 and the phase interworking of lower ribbon 2
Close, form the space that a cross section is square waveform, wood chip layer 5 can be made to form the layer structure that cross section is square waveform, wood
Layer 5 is considered to be worth doing by ribbon tight, the sound insulation value of needle punched non-woven fabrics, in the case of same grammes per square metre, flat can be effectively improved
Effect promoting 65%.By original 70-90 decibels, 20-40 decibels are reduced to.Because wood chip layer 5 is the layer that cross section is square waveform
Shape structure, each ribbon is set to form an independent insulation construction under the parcel of wood chip layer 5, so as to effectively increase pin
The sound insulation value of prick nonwoven cloth.
In the base fabric 3 of first base fabric 1 and second set pin 7, pin 7 sequentially pass through from up to down the first base fabric 1, on
Ribbon 4, wood chip layer 5, the base fabric 3 of lower ribbon 2 and second, the lower end connection wire rod 8 of pin 7, the sidepiece of screw mandrel 8 set open-work
