Abstract
The invention provides a method for compressing and filling foams. The method comprises the following steps: cutting a whole foam into strip-shaped foams according to a to-be-filled cavity; wrapping the strip-shaped foams with a PE (Poly Ethylene) film with a sealing effect that the yearly gas leakage rate is smaller than or equal to 5%, sealing along the length direction of the foams, and keeping two ends of each strip-shaped foam in a non-sealed state; vacuumizing from two ends by use of vacuumizing equipment, and sealing two ends after finishing vacuumizing. According to the method, the adopted foam is made of a foam material with good elasticity and high fire resistance, the cross section, provided with the to-be-filled cavity, of the foam is cut, the strip-shaped foams are wrapped with the PE film with high sealing performance and are vacuumized, so that compressed foams are formed, and the compressed foamed can expand automatically so as to be filled into the cavity as long as the sealing PE film is detached; the space for conveying and storing the foams can be reduced; large-volume foams are not directly stuffed into the cavity, so that the time required for installation is reduced.
Description
[technical field]
The present invention relates to packing material field, particularly relate to and adopt compression foam to carry out the mode of filling.
[background technique]
Foam is divided into PU foam, antistatic foam, conducting foam, EPE, antistatic EPE, PORON, CR, EVA, bridge formation PE, SBR, EPDM etc., have easy to use, bending freely, a series of feature such as ultra-thin, the reliable performance of volume.Utilize that it is flexible, lightweight, the characteristic of fire-proof and damp-proof can as buffering, thermal-protective material very well.The present invention be directed to and foam is applied to packing material field, prior art is generally foam is cut into the shape needing the die cavity of filling, then be directly tucked in die cavity, because the characteristic of foam itself, add to exist man-hour in filling and bulky problem in difficulty, storage and transportation process is installed.
[summary of the invention]
The present invention is directed to above situation and propose a kind of reduction installation difficulty, install, store and transport the method for the foam of compression filling all eaily.
The method of foam is filled in compression involved in the present invention, comprises;
The die cavity of filling as required, cuts monoblock foam, is cut into the foam of strip;
Adopt sealing effect: year leak rate≤5% PE film, PE film is wrapped in outside strip foam, along foam length direction envelope system, indwelling two ends non-closed state;
Adopt vaccum-pumping equipment to vacuumize from two ends, after foam bar volume shrinkage is to 30% of initial volume, PE film two ends are sealed.
The shape of cross section of the foam cut conforms to the cross section size of die cavity to be filled.
Compress the method that foam is filled, comprise;
The filling foam of compression is directly put into die cavity, then the sealing at PE film two ends is dismantled;
Foam self-expansion fills full die cavity, completes installation.
The foam material that the foam that employing this patent of the present invention uses selects good springiness, fireproof performance high, the cross-section area installing die cavity to be filled cuts, coated and vacuumize with the PE film of high sealing performance, form compression foam, the sealing PE film that only needs when being filled into die cavity to dismantle just can complete installation by self-expansion.The space that transport stores foam can be reduced; Directly the foam of large volume need not be filled in die cavity and reduce the time required for installing.
[accompanying drawing explanation]
Fig. 1 is that the present invention compresses filling foam compression schematic diagram;
Fig. 2 is that the present invention compresses the schematic diagram of filling foam filling die cavity;
Fig. 3 is the schematic diagram of compression foam self-expansion of the present invention;
Wherein: 10,10 ', foam; 20, PE film.
[embodiment]
Below in conjunction with the drawings and specific embodiments of the present invention, the present invention is described in further detail.
Prior art, in transport, work progress, because of the material behavior of foam own, has difficulties to the installation of transport and small space.In actual use, when having steam or water in die cavity, foam can absorb moisture, and self insulation, anti-acoustic capability reduce.According to compression method of the present invention, because smaller volume after compression, transport is installed all more convenient, can self-expansion after installation, plays the effect of filling die cavity.In addition, there is the protection of PE film, foam can be stoped to absorb water, insulation, the Noise Reduction of foam can be protected for a long time.
As accompanying drawing 1, the method for foam is filled in compression involved in the present invention, comprises;
The die cavity of filling as required, cuts monoblock foam, is cut into the bubble 10 of strip; The shape of cross section of the foam cut conforms to the cross section size of die cavity to be filled.
Adopt sealing effect: year leak rate≤5% PE film, PE film 20 is wrapped in outside strip foam 10, along foam 10 length direction envelope system, indwelling two ends non-closed state;
Adopt vaccum-pumping equipment to vacuumize from two ends, after foam bar volume shrinkage is to 30% of initial volume, PE film two ends is sealed, becomes the foam 10 ' of compressive state.
Compress the method that foam is filled, comprise;
As in Fig. 2, the filling foam 10 ' of compression is directly put into die cavity, then the sealing at PE film two ends is dismantled;
Foam self-expansion fills full die cavity, completes installation.As accompanying drawing 3 be expansion after design sketch is installed.
The foam material that the foam that employing this patent of the present invention uses selects good springiness, fireproof performance high, the cross-section area installing die cavity to be filled cuts, coated and vacuumize with the PE film of high sealing performance, form compression foam, the sealing PE film that only needs when being filled into die cavity to dismantle just can complete installation by self-expansion.The space that transport stores foam can be reduced; Directly the foam of large volume need not be filled in die cavity and reduce the time required for installing.
The above, it is only present pre-ferred embodiments, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solution of the present invention content, any simple modification that above embodiment is done is referred to according to the technology of the present invention, equivalent variations and modification, all belong in the scope of technical solution of the present invention.
