Abstract
The heated nozzle of a kind of hot melt gun disclosed by the invention, including nozzle body, it is provided with hot flow path in described nozzle body, described nozzle body is provided with glue-feeder and gum exudation mouth, described hot flow path is extended to gum exudation mouth by glue-feeder, the heating coil being enclosed within outside hot flow path it is additionally provided with in described nozzle body, described heating coil is formed by flat resistive heater helically coiling, the surface of resistive heater scribbles heat-resistant insulating layer, so, the heating surface (area) (HS of heating coil contacts bigger with hot flow path, the efficiency of heating surface is high, the PUR in entrance hot flow path is made to be maintained at molten condition, avoid PUR because of cooling and solidifying plug nozzle, structure is practical reliable.
Description
Technical field
The present invention relates to nozzle, the heated nozzle of a kind of hot melt gun.
Background technology
At present, hot melt gun is heated to molten condition by PUR, then utilizes nozzle to be ejected by PUR, existing
Hot melt gun nozzle not there is heating function, PUR easily cools and solidifies and plug nozzle when flowing through nozzle, be unfavorable for provide
Stable PUR output, nozzle cleaning is also inconvenient.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides the heated nozzle body of a kind of hot melt gun.
To achieve these goals, the technical solution adopted in the present invention is:
The heated nozzle of a kind of hot melt gun, including nozzle body, is provided with hot flow path, described nozzle body in described nozzle body
Being provided with glue-feeder and gum exudation mouth, described hot flow path is extended to gum exudation mouth by glue-feeder, is additionally provided with and is enclosed within described nozzle body
Heating coil outside hot flow path, described heating coil is formed by flat resistive heater helically coiling, resistive heater
Surface scribbles heat-resistant insulating layer.
Preferably, described heat-resistant insulating layer is polytrifluorochloroethylene.
Preferably, being provided with sealing ring at described glue-feeder, described sealing ring is refractory seals part.
Preferably, described gum exudation mouth is glue discharging mouth, and described glue discharging mouth is threadeded with nozzle body.
Beneficial effects of the present invention: set up heating coil in nozzle body, heating coil uses helical structure, so,
The heating surface (area) (HS of heating coil contacts bigger with hot flow path, and the efficiency of heating surface is high, makes the PUR in entrance hot flow path be maintained at molten
Melting state, it is to avoid PUR is plug nozzle because of cooling and solidifying, structure is practical reliable.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described further.
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
With reference to Fig. 1, the heated nozzle of a kind of hot melt gun that the present invention provides, including nozzle body 1, described nozzle body
Being provided with hot flow path in 1, described nozzle body 1 is provided with glue-feeder 2 and gum exudation mouth 3, and described hot flow path is extended to out by glue-feeder 2
Glue mouth 3, is additionally provided with the heating coil 4 being enclosed within outside hot flow path in described nozzle body 1, described heating coil 4 is by flat electricity
Resistance heating wire helically coiling forms, and the surface of resistive heater scribbles heat-resistant insulating layer, the structure of the not shown hot flow path of accompanying drawing.
This heating coil 4 spiral surrounding structure has elasticity, when reality is applied, is allowed to suitable by stretching heating coil 4
Answering the hot flow path of different length, the heating wire thermal response of flat structure is fast, homogeneous heating.So heat the heating surface of coil 4
Amassing and contact with hot flow path more greatly, the efficiency of heating surface is high, makes the PUR in entrance hot flow path be maintained at molten condition, it is to avoid PUR
The plug nozzle because of cooling and solidifying, structure is practical reliable.
In embodiment, heat-resistant insulating layer is polytrifluorochloroethylene, has good chemical stability, insulating properties and high temperature resistant
Property, effectively protect heating wire, structural safety is reliable.Being provided with sealing ring at glue-feeder 2, this sealing ring is refractory seals part.
This gum exudation mouth 3 is glue discharging mouth, and described glue discharging mouth is threadeded with nozzle body 1.
The above, simply presently preferred embodiments of the present invention, the invention is not limited in above-mentioned embodiment, as long as
It reaches the technique effect of the present invention with identical means, all should belong to protection scope of the present invention.
