Abstract
The invention provides a cutting knife for a coil. The cutting knife is used for cutting a building waterproof coil. The cutting knife comprises a knife handle and a knife head, wherein an electric heating tube is arranged on a knife back of the knife head; a power supply lead of the electric heating tube extends to a wiring terminal at the rear part of the knife handle; the power supply lead penetrates into the wiring terminal at the rear part of the knife handle from the inside of the knife handle; and a switch for connecting or disconnecting the power supply lead is arranged on the knife handle. According to the cutting knife for the coil, the resistance of cutting the waterproof coil can be effectively reduced and the wear speed of the knife head is reduced.
Description
Technical field
The present invention relates to a kind of cutter, especially, relate to a kind of cutter of building waterproof coil.
Background technology
In the process of deployment of building waterproof coil, according to various operating mode sizes, need to cut coiled material, because some more coil thickness are larger, therefore adopt scissor cut very hard, usually need to adopt cutter to carry out cutting-up.
In waterproof roll, to use morely a kind of is pitch type waterproof roll, and this kind coiled material is owing to have bitumen layer, during common cutter cutting, not only resistance is larger, and edge of a knife wearing and tearing are very fast, therefore for the cutting of asphalt water-proof coiled material, be a trouble operation in the work progress.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of coiled material cutter, these coiled material cutter can effectively reduce the resistance in the cutting waterproof roll process, and reduce the rate of wear of cutter head.
The technical solution adopted for the present invention to solve the technical problems is: these coiled material cutter comprise handle of a knife, cutter head, and the knife back of described cutter head is provided with electrothermal tube, and the current supply line of described electrothermal tube extends the binding post to described handle of a knife rear.
As preferably, described current supply line is worn to the binding post at handle of a knife rear from described handle of a knife inside, and described handle of a knife is provided with the switch of the described current supply line of break-make.
As preferably, also be provided with adiabatic protection press strip above the described electrothermal tube, with protection operating personnel's hand.
As preferably, described cutter head is made of copper, has good conduction effect.
As preferably, described cutter head is divided into two parts, the thickness of the first half is less than the thickness of Lower Half, and the ratio of first half height and Lower Half height is greater than 2:1, thus, can make the heat major part that is produced by electrothermal tube concentrate on Lower Half, that is concentrate on the blade place, make blade place temperature relatively stable, and reduced heat dissipation.
As preferably, described handle of a knife is made of hollow plastic body, and its surface is provided with anti-skidding lines, so that the laying of described current supply line.
Beneficial effect of the present invention is: these coiled material cutter are when the cutting waterproof roll, can heat cutter head by described electrothermal tube, make the blade place of cutter head keep higher temperature, this high temperature blade is touched to waterproof roll surface, and when slowly moving, will make waterproof roll, especially the Facing material of pitch type waterproof roll is subjected to thermal softening, thereby reduced the Cutting Drag of coiled material, made cutter head easily cut open coiled material, and reduced the rate of wear of cutter head.
Description of drawings
Fig. 1 is the structural representation of this coiled material cutter one embodiment.
Among the figure 1, handle of a knife; 3, electrothermal tube; 4, wire; 5, switch; 21, Lower Half; 22, the first half; 31, press strip; 41, binding post.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples:
In the embodiment shown in fig. 1, these coiled material cutter comprise handle of a knife 1, cutter head, the knife back of described cutter head is provided with electrothermal tube 3, the current supply line 4 of described electrothermal tube 3 is worn to the binding post 41 at handle of a knife 1 rear from described handle of a knife 1 inside, and described handle of a knife 1 is provided with the switch of the described current supply line 4 of break-make.
Above-mentioned coiled material cutter, described electrothermal tube 3 tops also are provided with adiabatic protection press strip 31, with protection operating personnel's hand.
Described cutter head is made of copper, and be divided into two parts, the thickness of the first half 22 is less than the thickness of Lower Half 21, and the ratio of the first half 22 height and Lower Half 21 height is greater than 2:1, thus, can make the heat major part that is produced by electrothermal tube 3 concentrate on Lower Half 21, that is concentrate on the blade place, make blade place temperature relatively stable, and reduced heat dissipation.
Above-mentioned coiled material cutter, described handle of a knife 1 is made of hollow plastic body, and its surface is provided with anti-skidding lines, so that the laying of described current supply line 4.
Above-mentioned coiled material cutter are when the cutting waterproof roll, can be by 3 pairs of cutter head heating of described electrothermal tube, make the blade place of cutter head keep higher temperature, this high temperature blade is touched to waterproof roll surface, and when slowly moving, will make waterproof roll, especially the Facing material of pitch type waterproof roll is subjected to thermal softening, thereby reduced the Cutting Drag of coiled material, made cutter head easily cut open coiled material, and reduced the rate of wear of cutter head.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
