The scrap rubber belt of the PET release films composition of row, the foam on upper strata compound with the scrap rubber belt and positioned at the scrap rubber belt
It glue-line and is covered in the upper strata of the foam glue-line and equipped with multiple protection cap bands with frame, is distributed in the foam glue-line
On be distributed at the time of molding generate waste material endoporus, the scrap rubber belt be equipped with and the corresponding waste discharge hole of the endoporus.
Narrow side adhesive tape in the utility model can reduce foamed glue narrow side product work in-process evacuation aperture give up during
The probability for phenomena such as generating piece, deformation, and product can make coiled strip and it is protected not deformed in winding, to meet volume
Expect automated production requirement, improve production efficiency, save production cost, be suitble to produce in enormous quantities.
In some embodiments, the hem width in the waste discharge hole is smaller 0.4mm than the endoporus.It is thus, it is possible to convenient under
Draw waste discharge.
In some embodiments, the foam glue-line is made of the foam rubber of model 3M VHB, the foam glue-line
Hem width for 0.3mm-0.5mm, the endoporus is circular and/or strip.Thus, it is possible to determine the material and ruler of foam glue-line
It is very little to wait attributes.
In some embodiments, the thickness of the protection cap band is 0.15mm.Thus, it is possible to determine the guarantor of protection cap band
Shield acts on, and prevents from deforming in winding when adhesive tape from making coiled strip
In some embodiments, the both sides of the scrap rubber belt are equipped with multiple lower calibration holes, on the protection cap band
Equipped with the lower corresponding upper calibration hole of calibration hole.Thus, it is possible to ensure accurately to set protection cap band.
Description of the drawings
Fig. 1 is a kind of schematic diagram of the narrow side adhesive tape of anti-deformation waste discharge of one embodiment of the utility model；
Fig. 2 is a kind of exploded view of the narrow side adhesive tape of anti-deformation waste discharge shown in Fig. 1.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 schematically shows a kind of a kind of narrow side glue of anti-deformation waste discharge of embodiment according to the present utility model
Band, Fig. 2 are the exploded view of adhesive tape in Fig. 1.As shown in Figs. 1-2, which is divided into three layers, including scrap rubber belt 1, foam rubber
Layer 2 and protection cap band 3.
Scrap rubber belt 1 is the waste tape of the one side alignment cut out using dise knife from PET release films, which is provided with waste discharge hole
11, foam glue-line 2 is compound with scrap rubber belt 1 and is located at the upper strata of scrap rubber belt 1, by the foam rubber group of model 3M86415VHB
Into opening up the endoporus 21 by multiple circular and/or strip thereon, the hem width of endoporus 21 is more than waste discharge hole 11, and protection cap band 3 covers
It covers on the upper strata of foam glue-line 2, protection cap band 3 is equipped with multiple band frames 31, can expose endoporus 21 by band frame 31.
In addition, the both sides of scrap rubber belt 1 are equipped with multiple lower calibration holes 12, protection cap band 3 is equipped with and lower calibration hole 12
Corresponding upper calibration hole 32.
In the adhesive tape in manufacturing the utility model, it is necessary first to determine the shape of required foam glue-line 2, such as hem width
With the size of endoporus 21 etc., then specific manufacturing step is as follows：
1) the scrap rubber belt 1 of one side alignment is cut out from PET release films using dise knife, is included in the centre of scrap rubber belt 1
Multiple waste discharge holes 11 are set and multiple lower calibration holes 12 are set in the both sides of scrap rubber belt 1, wherein, the position in waste discharge hole 11
It is corresponding with each endoporus 21 designed with shape, and its hem width is smaller than endoporus 21, hem width gap is about 0.4mm；
2) foam rubber is taken to be combined on scrap rubber belt 1, is processed using circular knife machine and cuts out the suitable foam glue-line 2 of hem width
And processing waste material is excluded, the hem width of wherein foam glue-line 2 is generally set to 0.3mm-0.5mm, belongs to narrow side adhesive tape；
3) a protection cap band 3 is cut out on circular knife machine and is covered in the upper strata of foam glue-line 2, to protect foam
Glue-line 2 will not deform when winding, wherein to open up the multiple band frames 31 in place in the center of protection cap band 3, can be revealed by band frame 31
Go out for processing the position of endoporus 21 on foam rubber layer 2, and the both sides of protection cap band 3 open up and locate on multiple and scrap rubber belt 1
The corresponding upper calibration hole 32 of lower calibration hole 12, to be calibrated when placing protection cap band 3, and the thickness of protection cap band 3
The desirable 0.15mm of degree；
4) machine is cut using set to be die cut the adhesive tape being combined by scrap rubber belt 1, foam glue-line 2 and protection cap band 3,
Endoporus 21 to be made on foam glue-line 2, and waste material is excluded using from waste discharge hole 11, endoporus 21 can be circular and/or strip,
Can be other suitable shapes, distribution can also be designed as needed.
During manufacture, the presence of the scrap rubber belt 1 due to being equipped with waste discharge hole 11 forms foam glue-line 2 in processing
Shape and during endoporus, generated waste material can be excluded from waste discharge hole 11 by way of drop-down, reduce work in-process
The probability for phenomena such as generating piece, deformation improves the quality of production, and is suitble to produce in enormous quantities.And depositing due to protection cap band 3
It when adhesive tape is made coiled strip, can play a protective role, adhesive tape is made not deformed in winding, disclosure satisfy that coiled strip is automatic
Change production requirement, improve production efficiency.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
