Description
Technical Field
The invention relates to the field of double-sided adhesive tape product punching, in particular to a double-sided adhesive tape punching method with a narrow width, quick re-adhesion and a long handle.
Background
The handle of the double-sided adhesive tape product to be handled is not provided with the double-sided adhesive tape, so that the double-sided adhesive tape product is convenient to take when in use, and the handle can be arranged at the end part of the product. For double-sided adhesive tape products with narrow width, thick thickness, quick re-adhesion and long handles, a process method of punching and arranging at present is needed during preparation.
Referring to fig. 1, a die cutting process in the prior art includes the following overall steps: firstly, a handle is laminated from a film and an auxiliary protective film, then a double-sided adhesive layer is coated, raw paper on the double-sided adhesive is torn off, auxiliary release paper is pasted on the auxiliary release paper, then die cutting is carried out, the outline of the handle is punched out, the handle and the auxiliary release paper with the outline are torn off, a waste discharge Mylar layer is pasted on the auxiliary release paper, rolling is carried out, waste discharge is carried out by tearing the Mylar layer, a material belt bearing film is pasted on the auxiliary release paper, rolling is carried out, the auxiliary protective film and the outline of the handle film are torn off from the lower part of the material belt, a finished material belt is obtained, and the material belt is wound.
In the preparation process of the double-sided adhesive tape product with the narrow width and the long handle, the product obtained by punching is easily taken away by the mylar layer due to the characteristics of narrow width and quick re-adhesion, see fig. 3, which causes serious sheet dropping phenomenon, so that the reject ratio of the product reaches more than 80%, and therefore, the automatic waste removing process cannot be realized after punching, the waste can only be manually removed, the whole efficiency is seriously influenced, and how to realize automatic waste removing is a problem to be solved urgently.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a double-sided adhesive tape punching method with a narrow width, quick re-adhesion and a long handle, which can realize automatic waste removal and can control the reject ratio to be below 0.5%.
Firstly, the invention carries out mechanism analysis from the origin of the problem: the phenomenon of sticking occurs mainly because the long handle double faced adhesive tape product is too narrow, the bearable pulling force limit between the double faced adhesive tape layers at the punching fracture position of the double faced adhesive tape layer is larger than the adhesive force of the release film on the product to the double faced adhesive tape layer, so that the double faced adhesive tape layer which is arranged around is pulled up by the double faced adhesive tape layer in the product area, and the product yield is seriously reduced along with the wheat pulling layer which is peeled off together.
Based on the analysis of the mechanism, the purpose of the invention can be realized by the following technical scheme:
the double-sided adhesive tape punching method with the narrow width, quick adhesive recovery and the long handle comprises the following steps:
s1: presetting of cutter and double-sided adhesive layer
Typesetting the double-sided adhesive layer to enable an included angle alpha between the position of a product on the preset double-sided adhesive layer and the width direction of the material belt to be = 20-55 degrees;
the angle of the cutter is set, so that an included angle formed between the cutter and the width direction of the material belt is alpha;
s2: die cutting of laminated film
Covering the handle release film and the auxiliary protective film with the typeset double-sided adhesive layer in the S1;
covering auxiliary release paper on the double-sided adhesive tape layer;
punching out a handle part;
s3: waste discharge
Removing the auxiliary release paper;
discharging the outline area of the double-sided adhesive layer through waste discharging mylar;
covering a material belt bearing film;
tearing off the auxiliary protective film and the profile of the handle release film;
and rolling the finished material belt.
Furthermore, a virtual product punching position is preset on the preset double-sided adhesive layer, and a handle part of the product punching position is a hollow area.
Further, preset that the die-cut position of virtual product and the width direction in material area are the contained angle alpha =20~55, and the fretwork area of handle portion is towards the walking material direction in material area.
Further, the preset virtual product punching position forms an included angle alpha =30 degrees with the width direction of the material belt.
Further, the thickness of the double-sided adhesive layer is 0.1 mm.
Further, the product area obtained after punching is strip-shaped, and the handle area is arranged at the end part of the strip-shaped area.
Further, the stroke of punching in S2 is to cut off the auxiliary release paper, the double-sided adhesive layer, and the handle release film from top to bottom in sequence.
Further, the auxiliary release paper is discharged by attaching and tearing the waste discharge tape in S3.
Further, in S3, the carrier film is covered on the handle release film from above, so that the double-sided adhesive tape of the product left after tearing off the waste wheat pull is sandwiched between the carrier film and the handle release film.
The action mechanism is as follows: when tearing supplementary protection film and handle membrane from type membrane profile by the material belt below, because the direction of tearing the material area is just in time opposite with the direction of walking the material, just so make the handle portion not be equipped with the regional exposure of double faced adhesive tape earlier, make the regional handle region of double faced adhesive tape profile and double faced adhesive tape carry out progressively by the handle end and separate, the power scope of the pulling force of die-cut clearance is far less than the pulling force when not carrying out the position rotation in progressively the separation process, make the regional easier separation of handle region of double faced adhesive tape profile and double faced adhesive tape, can make the product double faced adhesive tape be difficult to be taken away by the wheat pull layer of wasting discharge.
Compared with the prior art, the invention has the following advantages:
1) the angle rotation adjustment through whole processing has realized the firm security of product double faced adhesive tape, the yield of the promotion product that is showing for the defective rate falls to 0.5% and below, has replaced the artifical waste discharge process of this technology, the promotion productivity that is showing.
2) The process improvement method can be widely applied to the production lines of various long-handle double-sided adhesive tape products, and has the advantages of convenient process improvement and simple and convenient operation.
