Description
Technical Field
The invention belongs to the technical field of die cutting, and particularly relates to a bridging semi-finished product for solving the problem of poor backing paper and a bridging process thereof.
Background
Foam cotton materials are increasingly used in the current die cutting industry, and have the characteristics of loose surface materials and low density, but foam cotton has strict requirements on the selection of a protective film, for example, if the protective film is heavier, the problem of foam cotton tearing can occur, and if the protective film is lighter, the problem of bottom paper remaining in the product can occur, so far, a proper protective film is not found to be actually matched with the foam cotton, so that the raw materials are greatly wasted in the die cutting production process. At present, 90% of the problems of die-cut products using foam are the reverse type problem, which is also the most complaint problem by customers, and the reverse type problem is the cancer of the products and is difficult to eradicate completely. However, the die-cut product has high raw material value and large specific gravity of the total cost of the product, and due to the existence of the reverse release type problem, the raw material cost is greatly increased, and the market competitiveness of the die-cut product is seriously reduced.
Disclosure of Invention
The invention provides a bridging semi-finished product for solving the problem of poor residual bottom paper and a bridging process thereof, aiming at the problem of reverse parting of die-cut products using foam in the prior art.
The invention adopts the following technical scheme:
the utility model provides a semi-manufactured goods of bridge for solving and staying the bad bridge of end paper, semi-manufactured goods of bridge is used for bearing cross cutting product, the cross cutting product includes the pad film and laminates in the protection film of pad film top surface, just the protection film extends the extension that a section distance constitutes the protection film in the one end of pad film, semi-manufactured goods of bridge is including the end paper of locating the bottom, the end paper is equipped with the bed hedgehopping portion of a plurality of bars side by side along its extending direction, the top surface of bed hedgehopping portion with the partial bottom surface of the extension of protection film is laminated mutually, and bed hedgehopping portion makes and leaves the clearance between the bottom surface of pad film and the top surface of end paper, wherein, the application of force position when the part of laminating mutually with the top surface of bed hedgehopping portion of protection film is for.
Further, the heightening part comprises foam arranged at the top of the heightening part, and the top surface of the foam is attached to the partial bottom surface of the extension part of the protective film.
Further, the padding part is composed of a silica gel belt, double faced adhesive tapes and foam cotton which are arranged from bottom to top in sequence.
Further, the top surface of the foam is a PET surface.
The bridging process for solving the problem of poor bridging semi-finished products with the backing paper comprises the following steps of sequentially stacking the backing paper and the padding material from bottom to top and compounding, half-cutting the backing paper to the upper surface of the backing paper by using a circular cutter slitting cutter, removing waste of the padding material, and leaving a strip-shaped padding part.
Preferably, the bridging process comprises the following steps of sequentially stacking and compounding a low-adhesive film, base paper and a padding material from bottom to top, half-cutting the composite material to the upper surface of the base paper by using a circular cutter slitting knife, removing waste of the padding material, reserving a strip-shaped padding part, and stripping the low-adhesive film; the padding material is composed of a silica gel belt, double faced adhesive tapes and foam cotton which are sequentially overlapped from bottom to top.
The invention has the following beneficial effects:
foam used for die-cut products, such as 06 foam and SG foam, is difficult to match with a protective film due to the influence of the surface structure and the density, the reverse release ratio is large, and further the control in production is difficult, the process yield is low, and the production cost is increased. The reverse release type problem comprises two conditions of bottom paper retention and difficult peeling, wherein in the peeling process, the protective film is lifted, and the sticking film is not lifted away along with the protective film and is retained on the bottom paper, so that the bottom paper retention is poor; the difficult peeling means that the die-cut product is stuck on a stuck object (a steel plate/a plastic plate/a PC plate, etc.), the protective film is taken off, and the protective film takes the sticking film from the stuck object.
The invention develops a bridging process aiming at the problem of poor bottom paper retention, and mainly takes foam as a height part to prevent a die-cut product from contacting with the bottom paper, a certain gap is reserved between the die-cut product and the bottom paper, and the adhesive film and the bottom paper do not need to contact with each other due to the arrangement of the gap, so that the possibility that the adhesive film is retained on the bottom paper is fundamentally avoided, and a customer can directly clamp the die-cut product when using the adhesive film; therefore, the process yield of die-cut products is effectively improved, the raw material cost is reduced, and the production cost is obviously reduced. Furthermore, the top surface of the raised part of the invention is jointed with the partial bottom surface of the extending part of the protective film, the part of the bottom surface of the extending part of the protective film, which is not jointed with the top surface of the raised part, is a force application position when the die-cut product is taken down.
In addition, by using the bridging process, the protective film with proper gram weight matched with the foam is not required to be found without wasting energy and time, the requirement on the release force of the base paper is low, excessive resources are not required to be spent on researching the adaptation of the base paper and the glue, the research and development resources are saved, the research and development period is shortened, and the bridge is beneficial to the survival development of enterprises.
