Abstract

The utility model discloses a foam cutting pen. A pen head comprises a metal fin catheter, an electric heating wire and a high-temperature insulation material layer, wherein the metal fine catheter is covered outside the electric heating wire, the high-temperature insulation material layer is used in the middle for separation, the free bending can be realized, in the work process, the electric heating wire generates heat and can transfer heat to the metal fine catheter, then, the metal fine catheter is used for cutting fusible objects such foam plates, and the electric heating wire is prevented from being in direct contact with the cut materials. The multifunctional foam cutting pen has the advantages that the structure is simple, the manufacturing cost is low, no cut exists at the cut foam edges, and meanwhile, various styles of foam such as S-shaped foam, O-shaped foam, W-shaped foam can be cut.

Description

A kind of foam cutting pen

Technical field

The utility model relates to cutting field, relates in particular to a kind of foam cutting pen.

Background technology

By electrical heating and hot melt principle, cutting the fusible materials such as cystosepiment has been widely used, using at present maximum traditional approach is stretching heating wire access electric loop, electric current makes heating wire produce enough heats by heating wire, utilizes this heat directly to cut fusible material.

This traditional cutting pen has following deficiency:

1. can only be from the edge feed of cut material, otch cannot seal;

2. because heating wire directly contacts cut material, in cutting process as power down or electric current too little, heating wire is just easy to be pulled apart by material, service life is shorter;

3. can only be linear incision during cutting material, can not cut out the otch of other patterns.

Utility model content

Technical problem to be solved in the utility model is the defect for background technology, and a kind of foam cutting pen that can insert cutting, long service life from cutting material optional position and have multiple slit patterns is provided.

The utility model is for solving the problems of the technologies described above by the following technical solutions:

A kind of foam cutting pen, comprise nib, body, switch, copper seat, terminal, porcelain bushing and power interface, wherein nib is connected with a body, switch is arranged on it pen, copper seat, terminal and porcelain bushing are arranged on a body towards written one end, power interface is arranged on a body away from written one end, copper seat, switch, power interface, terminal is electrically connected successively, copper seat and terminal separate by porcelain bushing, nib comprises flexible metal fine duct, heating wire and high temperature insulating material layer, flexible metal fine duct is wrapped in heating wire outside, between heating wire and flexible metal fine duct, by high temperature insulating material layer, separate, heating wire one end and terminal are electrically connected, the other end and flexible metal fine duct are electrically connected away from one end of terminal, flexible the metal fine duct other end and copper seat are electrically connected.

As the further prioritization scheme of the utility model, described metal fine duct adopts copper material to make.

As the further prioritization scheme of the utility model, described metal fine duct adopts stainless steel material to make.

The utility model adopts above technical scheme compared with prior art, has following technique effect:

1. metal fine duct can directly be inserted into cut material from optional position, without the edge feed from material;

2. metal fine duct can be bent to various required shapes, cuts out the foam of multiple slit patterns;

3. heating wire does not directly contact cutting material, long service life.

Fig. 3 is the partial enlarged view of foam cutting pen;

Fig. 4 is the schematic diagram that foam cutting pen is used state.

The specific embodiment

Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail:

As Fig. 1, 2, shown in 3, the utility model discloses a kind of foam cutting pen, comprise nib, body, switch 7, copper seat 3, terminal 5, porcelain bushing 9 and power interface 8, wherein nib is connected with a body, switch 7 is arranged on it pen, copper seat 3, terminal 5 and porcelain bushing 9 are arranged on a body towards written one end, power interface 8 is arranged on a body away from written one end, copper seat 3, switch 7, power interface 8, terminal 5 is electrically connected successively, copper seat 3 and terminal 5 separate by porcelain bushing 9, nib comprises flexible metal fine duct 1, heating wire 2 and high temperature insulating material layer 4, flexible metal fine duct 1 is wrapped in heating wire 2 outsides, between heating wire 2 and flexible metal fine duct 1, by high temperature insulating material layer 4, separate, heating wire 2 one end and terminal 5 are electrically connected, the other end and flexible metal fine duct 1 are electrically connected away from one end of terminal 5, flexible metal fine duct 1 other end and copper seat 3 are electrically connected.

Power interface 8 is communicated with power supply and opens after switch 7, and electric current utilizes metal fine duct 1 to form loop, heating wire 2 heatings, and heat passes to metal fine duct 1, by the metal fine duct 1 heating, cuts the meltable objects such as cystosepiment.

Metal fine duct can adopt copper material to make, and such nib is softer, can compare large flexure operation, but while using, action is unsuitable excessive;

Metal fine duct also can adopt stainless steel material to make, and such nib is harder, use more convenient, but the crooked amplitude of nib is limited.

As shown in Figure 4, nib can be bent to various required shapes, as S type, therefore can cut out the foam of multiple slit patterns.

Claims

1. a foam cutting pen, comprise nib, body, switch, copper seat, terminal, porcelain bushing and power interface, wherein nib is connected with a body, switch is arranged on it pen, copper seat, terminal and porcelain bushing are arranged on a body towards written one end, power interface is arranged on a body away from written one end, copper seat, switch, power interface, terminal is electrically connected successively, copper seat and terminal separate by porcelain bushing, it is characterized in that, nib comprises flexible metal fine duct, heating wire and high temperature insulating material layer, flexible metal fine duct is wrapped in heating wire outside, between heating wire and flexible metal fine duct, by high temperature insulating material layer, separate, described heating wire one end and terminal are electrically connected, the other end and flexible metal fine duct are electrically connected away from one end of terminal, the metal fine duct other end and the copper seat of described flexibility are electrically connected.
