Description
Technical field
The utility model relates to heat melting device accessory technical field, more particularly to a kind of improvement hot melt die head.
Background technology
The conventional design of heat container is all the protection of heat container itself, and how die-filling head, heating is fast, good heat dissipation, and dress overheat is protected
Shield etc., uniquely without solving the problems, such as to be primarily present, specifically, it occur frequently that molten bad pipe fitting during heat melting device use
Problem, cause pipe fitting can not normal use, cause the waste of resource.
In addition, heat melting device is in use, high-temperature digestion tubing, pungent niff is produced, the time for dissolving tubing gets over
Short, the peculiar smell of human body suction is fewer, and injury is also small, because existing heat melting device has the problem of melting bad tubing, not only causes
The waste of material, it is necessary to do over again again for workmen, secondary injury is caused to the health of workmen.
Exemplified by designing the pipeline of 32 specifications, heated using existing heat melting device, the tubing after hot melt can only achieve
The flow of 15 specification pipelines.This heat melting device is in use, occurs being welded interface or the phenomenon of the small interface of weldering is very more.Original heat
The tube wall of adapter material is just thick, and caliber is just small, and hot melt produces molten stifled or melts the small mouth of pipe again when operating, water throughput will greatly subtract
It is weak.Flow and pressure can reduce simultaneously.Pipe diameter determing is changed again, and labor people works with one's mind, waste of resource.
Utility model content
To solve problems of the prior art, the utility model provides a kind of improvement hot melt die head.
The purpose of this utility model implements by the following technical programs：
One kind improvement hot melt die head, including die head body, the die head body have an inner chamber, the inner chamber include side wall with
Bottom, heat-proof device is provided with the inner chamber bottom of the die head, and the heat-proof device is the intracavity sidewall and the inner chamber
The temperature difference be present in bottom.
Further, the heat-proof device makes the intracavity sidewall temperature be higher than inner chamber bottom temperature.
Further, the heat-proof device is heat insulating mattress, be provided between the heat insulating mattress and the inner chamber bottom every
Heat space.
Further, the heat-proof device is heat insulating coat, and the heat insulating coat is completely covered on the inner chamber bottom.
Further, the heat-proof device is pipe close, and the pipe close includes the pipe being coaxially disposed with the side wall of the inner chamber
Side wall is filled in, described that the pipe close side wall ends are provided with pipe close head, the pipe close head be arranged in parallel with the inner chamber bottom.
Further, the pipe close side wall external diameter is less than or equal to hot melt pipe internal diameter.
Improvement hot melt die head disclosed in the utility model, by setting heat-proof device, profit in hot melt die head inner chamber bottom
With the principle of the temperature difference, it is that the obvious temperature difference is arranged at the periphery of die head and bottom that heat insulation and heat control processing is done in the bottom of die head, is avoided
Tubing produces phenomenon that is molten stifled or melting the small mouth of pipe in reflow process, solves the problems, such as superheated well, has reached pre-
The effect of phase.
Brief description of the drawings

Fig. 2 is that the improvement disclosed in the utility model embodiment 2 heats die head schematic diagram；
Fig. 3 is that the improvement disclosed in the utility model embodiment 3 heats die head schematic diagram.
Embodiment
The utility model embodiment is described in detail with reference to specific embodiment.
Embodiment 1：
As shown in figure 1, the utility model discloses one kind to improve hot melt die head, including die head body, the die head body
With inner chamber 1, the inner chamber 1 includes side wall and 2 bottoms 3, and the inner chamber bottom 3 of the die head is provided with heat-proof device, described
Heat-proof device is that the intracavity sidewall 2 has the temperature difference with the inner chamber bottom 3.Specifically, in the present embodiment, the heat-insulated dress
Heat insulating mattress 4 is set to, insulated space 5 is provided between the heat insulating mattress 4 and the inner chamber bottom 3, insulated space 5 passes through air
Heat insulating mattress 4 and inner chamber bottom 3 are split.
Embodiment 2：
One kind improvement hot melt die head, including die head body, the die head body have inner chamber 1, and the inner chamber 1 includes side wall
2 with bottom 3, heat-proof device is provided with the inner chamber bottom 3 of the die head, the heat-proof device is the intracavity sidewall 2 and institute
State inner chamber bottom 3 and the temperature difference be present.Specifically, in the present embodiment, the heat-proof device is heat insulating coat 6, the heat insulating coat 6
It is completely covered on the inner chamber bottom 3.The temperature of inner chamber bottom 3 is controlled by heat insulating coat 6, ensures intracavity sidewall 2 and inner chamber
The temperature difference be present in bottom 3.
Embodiment 3：
One kind improvement hot melt die head, including die head body, the die head body have inner chamber 1, and the inner chamber includes side wall 2
With bottom 3, be provided with heat-proof device in the inner chamber bottom 3 of the die head, the heat-proof device be the intracavity sidewall with it is described
The temperature difference be present in inner chamber bottom.In the present embodiment, the heat-proof device is pipe close, and the pipe close includes the side wall with the inner chamber
The 2 pipe close side walls 7 being coaxially disposed, it is described to have a pipe close first 8 in the end set of pipe close side wall 7, the pipe close first 8 with it is described interior
Bottom of chamber end 3 be arranged in parallel, and the external diameter of pipe close side wall 7 is less than or equal to the hot melt internal diameter of tubing 9.
The concrete operation method of this case improvement hot melt die head：
