Abstract
The utility model provides a dust protected heating collar, includes and is equipped with the heat preservation on the inside wall of casing by the shaft type casing, the heat preservation inboard is equipped with the reflection stratum, and the casing both ends are equipped with annular connecting portion, is equipped with a plurality of infrared nanometer heating pipes that set up along the casing axial between the annular connecting portion at both ends, be equipped with the dustproof construction of sealing annular connecting portion inner ring opening on the annular connecting portion. The utility model has the advantages of simple structure and reasonable design, not only remain energy -conserving, the thermal -insulated advantage of current heating collar, moreover through addding the dustproof construction, avoided when idle the dust to get into the heating collar and caused the influence to its performance, prolonged life, saved the cost.
Description
Technical field
The utility model relates to the electric-heating technology field for plastics-production, particularly a kind of dust protected heating collar.
Background technology
Injection machine utilizes mould for plastics to make the main former of the plastic products of various shape thermoplastic or thermosetting material.In the process using injection machine to process various plastics, need to be heated to molten condition to the pellet in barrel or powdered plastic raw material, then the raw materials for plastics production of molten condition are injected in closed die cavity, after solidifying and setting, obtain plastic products.
In existing injecting machine material tube heating collar, owing to not arranging dustproof construction, and dust is many in workshop, when the idle placement of heating collar, dust easily enters in heating collar, affect the effect of heat-insulation layer, reflecting layer and zone of heating, not only heat and reduce every, hot property, and affect the service life of heating collar.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of dust protected heating collar rational in infrastructure, easy to use.
For solving the problems of the technologies described above, the utility model have employed following technical proposals:
A kind of dust protected heating collar, comprise the housing of tubular, the madial wall of housing is provided with heat-insulation layer, reflecting layer is provided with inside described heat-insulation layer, housing two ends are provided with annular connecting portion, between the annular connecting portion at two ends, be provided with some infrared nanometer heating tubes axially arranged along housing, described annular connecting portion is provided with the dustproof construction sealed by annular connecting portion inner ring opening.
Preferably, described dustproof construction comprises the guide groove be located on annular connecting portion internal ring wall, the dustproof sheet that annular connecting portion inner ring opening can be sealed be provided with dial-out in guide groove after.
Preferably, described dustproof sheet is made up of the semicircle slide plate that two are located in guide groove relatively, annular connecting portion inner ring opening can be sealed after described semicircle slide plate slides in opposite directions.
Preferably, the circle centre position of described semicircle slide plate is equipped with plectrum.
Preferably, described heat-insulation layer is aerogel layer.
Preferably, described reflecting layer is silver reflecting layer.
Compared with prior art, the utility model structure is simple, reasonable in design, not only remains the advantage that existing heating collar is energy-conservation, heat insulation, and by setting up dustproof construction, when avoiding idle, dust enters heating collar and impacts its performance, extends service life, provides cost savings.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation that in the utility model embodiment, annular connecting portion inner ring opening is in closed state;
Fig. 3 is the top view of the utility model embodiment.
Specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is described further.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1 and Figure 2, a kind of dust protected heating collar, comprise the housing 1 of tubular, the madial wall of housing 1 is provided with heat-insulation layer, reflecting layer is provided with inside described heat-insulation layer, housing 1 two ends are provided with annular connecting portion 2, and between the annular connecting portion 2 at two ends, be provided with some infrared nanometer heating tubes 3 axially arranged along housing 1, described annular connecting portion 2 is provided with the dustproof construction sealed by annular connecting portion 2 inner ring opening.
In the present embodiment, described dustproof construction comprises the guide groove 4 be located on annular connecting portion 2 internal ring wall, the dustproof sheet 5 that annular connecting portion 2 inner ring opening can be sealed be provided with dial-out in guide groove 4 after, dustproof sheet 5 is made up of the semicircle slide plate that two are located in guide groove 4 relatively, annular connecting portion 2 inner ring opening can be sealed after described semicircle slide plate slides in opposite directions.For the ease of operation, the circle centre position of described semicircle slide plate is equipped with plectrum 6.
When heating collar leaves unused, stir two plectrums 6 of housing 1 one end, two semicircle slide plates are slided in opposite directions, and the inner ring opening of annular this side of connecting portion 2 is sealed, in like manner, stir two plectrums 6 of housing 1 other end, two semicircle slide plates are slided in opposite directions, and the inner ring opening of annular this side of connecting portion 2 is sealed, now, heating collar entirety forms an airtight space, avoids dust to enter heating collar inside, realizes dust-proof effect.During work, dustproof sheet 5 is hidden in the guide groove 4 on annular connecting portion 2 internal ring wall, and heating collar is set in barrel surface, does not affect it and normally uses.
Reflecting layer is silver reflecting layer, adds the heat-insulation layer be made up of aeroge, during work; heat leakage is little, saves electric energy, simultaneously; can effectively prevent heat energy dissipation in extraneous production environment; heating collar housing outer surface temperature is very low, only has 45 degree to 70 degree, can protect staff on the one hand; avoid being burned; reduce the cost to production environment cooling on the other hand, decrease the negative effect of working environment to staff, add the work incentive of staff.
The utility model structure is simple, reasonable in design, not only remains the advantage that existing heating collar is energy-conservation, heat insulation, and by setting up dustproof construction, and when avoiding idle, dust enters heating collar and impacts its performance, extends service life, provides cost savings.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to the utility model claims.
