Abstract
The utility model discloses a hot knife tool for composite plastic membrane and/or plastic woven fabric, which is formed into integration by a lining board (1) and a hot knife (2), wherein the longitudinal end of the hot knife (2) is extended and exposed at the outer part of the lining board (1), and the main characteristic of the utility model is the corrugation-shaped cross section of the hot knife (2). The utility model can enhance the bonding strength of composite plastic membrane and/or plastic woven fabric which are processed and cut in a hot way.
Description
Technical field
The utility model relates to a kind of fervent cutter that is used for composite plastic film and/or plastic woven cloth, belongs to the plastics machinery technical field.
Background technology
The hot knife of the fervent cutter of existing composite plastic film and/or plastic woven cloth, it all is the linearity structure, it is cutting composite plastic film and/or plastic woven cloth such as cutting the cylindrical plastic woven cloth when producing Polywoven Bag, because its fervent mouthful is straight line, so that the hot adhesion intensity of the fervent oral area position between its compound woven cloth is lower.Although it also needs fervent oral area position suturing with thread management, but the material of its packaging is attritive powder shape material particularly, still can be from the gap at suture position, low by thermojunction intensity, extremely easy ruined thermal bond site, be scattered in the packaging bag and fly upward out, and cause negative consequence for the owner of cargo's property and environment.
Summary of the invention
The purpose of this utility model is to provide a kind of fervent cutter that is used for composite plastic film and/or plastic woven cloth that can effectively improve the hot adhesion intensity of composite plastic film and/or the fervent oral area of plastic woven cloth position, to overcome the deficiency of prior art.
The conception that realizes the technical scheme that the utility model purpose is adopted is the bond length that prolongs said fervent oral area position as far as possible, with the cohesive force of the said fervent oral area of effective raising position.
The utility model realizes that the technical scheme of its purpose is, a kind of fervent cutter that is used for composite plastic film and/or plastic woven cloth is formed one by liner plate and hot knife; A hot knife end longitudinally stretches outside at liner plate, and its improvement is: the cross section of hot knife is corrugated.
Can understand by above given technical scheme, the utility model is owing to adopted the corrugated hot knife, by its composite plastic film earnestly processed and/or the hot adhesion length of plastic woven cloth, obtained very big increase, thereby realized the purpose of this utility model undoubtedly.
The further improvement of the utility model point is:
Liner plate and hot knife are one.That is to say liner plate and hot knife, is the semifinished product of using with a kind of metal material, through digging or milling the said fervent cutter of being processed into.
Corrugated hot knife and liner plate composite welding by sheet steel plate Via foldable type are integral.That is to say,, be processed into the corrugated hot knife, and then corrugated hot knife and liner plate composite welding are integral strip of sheet steel plate stainless sheet steel for example.
Between corrugated hot knife and liner plate, be filled with the metal layer in by the gap that composite welding constituted.Its purpose obviously is for the braze layer for example of the metal layer by institute's filling, makes by the heat that electric heater produces that is located at the liner plate opposite side and conducts well to the corrugated hot knife, can effectively improve the thermal efficiency and saves energy like this.
The corrugated of said hot knife is the sawtooth corrugated, or trapezoidal corrugated, or the circular arc corrugated, or the sine bellows shape.Can certainly adopt the corrugated of other shape.Be intended to effectively improve under the prerequisite of said fervent mouthful of adhesion strength, satisfy user's needs.
After the utility model technique scheme was implemented, composite plastic film that it had and/or plastic woven cloth be the high advance of adhesion strength of mouth earnestly, is self-evident.

The specific embodiment
In fact by above given accompanying drawing, can understand that the utility model realizes the technical scheme of its purpose.Below in conjunction with the description of accompanying drawing by the specific embodiment, the utility model is described in further detail.
One of specific embodiment, shown in accompanying drawing 1,2,3, a kind of fervent cutter that is used for composite plastic film and/or plastic woven cloth, form one by liner plate 1 and hot knife 2, hot knife 2 end longitudinally stretches outside at liner plate 1, and the cross section of said hot knife 2 is corrugated, and liner plate 1 and hot knife 2 are through digging or milling that to process and make both are one with the stainless steel steel billet.The corrugated of said hot knife 2 is trapezoidal corrugated.
Two of the specific embodiment is shown in accompanying drawing 4,5.A kind of fervent cutter that is used for composite plastic film and/or plastic woven cloth, corrugated hot knife 2 and liner plate 1 composite welding all-in-one-piece by sheet stainless-steel sheet Via foldable type, between corrugated hot knife 2 and liner plate 1, be filled with metal layer 3 in by the gap that composite welding constituted, the corrugated of corrugated hot knife 2 is sawtooth corrugated, and metal layer 3 is a braze layer.Other is as one of specific embodiment.
The utility model installation lab scale production result shows it is very successful.
