Description
Technical field
The utility model relates to a kind of fan blade, relates in particular to a kind of ceiling fan blade.
Background technique
By the made fan blade of MDF, its moisture absorption, water absorbing properties, thickness swelling are higher, and be easily sagging therefore dimensional stability is relatively poor, and the fan blade density of being made by MDF simultaneously is larger, affects running efficiency and energy consumption is high.
With the made fan blade of natural timber, can have that air spots is smooth, the situation of Density inhomogeneity everywhere, can make like this blade weight on weight differ, cause fan running uneven, reduce working life, and the moistureproof and waterproof performance of this kind fan blade is also relatively poor.And the fan blade price of being produced by materials such as polystyrene material (ABS), PC and PPO is more expensive, not economical and practical.
Therefore, we are in the urgent need to a kind of quality is even, moistureproof and waterproof is good, the fan blade of reasonable price.
The model utility content
For the deficiencies in the prior art, thereby the technical problems to be solved in the utility model is to provide that a kind of rigidity is strong, density equalization, quality gently can improve fan running usefulness and moistureproof and waterproof is good, the fan blade of reasonable price.
For achieving the above object, the utility model adopts following technological scheme to realize:
A kind of fan blade is characterized in that: comprise substrate and the top layer that is connected with described baseplate-laminating, described substrate adopts the PVC foamed board.
As the improvement of a kind of fan blade technological scheme of the utility model, described top layer is PVC decorating film or the PE decorating film that fits in described substrate surface.Preferably, carry out moulding processing and utilize described PVC decorating film or PE decorating film to carry out veneer or coating at substrate surface.
Another kind as a kind of fan blade technological scheme of the utility model improves, and described top layer is wooden skin or the metallic film that fits in substrate surface.
As another improvement of a kind of fan blade technological scheme of the utility model, described top layer is the three-dimensional edition line that adopts high pressing mold pressurization to form at substrate surface.
As improvement of the technical scheme, oil film printing or water transfer printing or thermal transfer printing have been carried out in described top layer.
As improvement of the technical scheme, described substrate upper and lower surface is equipped with described top layer.
As improvement of the technical scheme, the edge of described fan blade is provided with chamfered edge.
As improvement of the technical scheme, the density of described PVC foamed board is 0.55～0.80g ∕ cm
3
As improvement of the technical scheme, the thickness of described PVC foamed board is 4.6～8.0 millimeters.
It is substrate that the utility model adopts the PVC foamed board, compares with existing fan blade, and quality is slim and graceful, can improve the running usefulness of fan; Anti-flaming, moistureproof and waterproof is good; Quality is even, is conducive to counterweight complete; And rigidity is strong; Have an even surface simultaneously, reasonable price; And can recycle, be conducive to environmental protection.
Description of drawings
Fig. 1 is a kind of fan blade embodiment's of the utility model structural representation;
Fig. 2 is a kind of another embodiment's of fan blade of the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is illustrated in further detail.
Fig. 1 is the overall structure schematic diagram of a kind of fan blade of the utility model, and the utility model mainly is comprised of 2 parts, substrate 1, top layer 2.Substrate 1 is fitted and connected with top layer 2, and substrate 1 adopts the PVC foamed board.So-called PVC foamed board (Polyvinyl chloride foam Board) can be described as again and avenges not plate and An Di plate, and its chemical composition is PVC＝polyvinyl chloride.
The utility model embodiment is substrate because fan blade adopts the PVC foamed board, and quality is slim and graceful, can improve the running usefulness of fan, and rigidity is strong simultaneously, in the time of can guaranteeing ceiling fan work to the rigidity requirement of flabellum; The PVC foamed board has an even surface, and the natural flaw without natural timber can reduce the product reject ratio; Anti-flaming property is good, not combustion-supporting and not spontaneous combustion, and moistureproof and waterproof might as well, can imbibition, thereby can be used for outdoor gardenly ceiling fan; PVC foamed board quality is even, is conducive to counterweight complete; In addition, compared to the fan blade that the materials such as existing polystyrene series (ABS), PC and PPO are produced, PVC foamed board low price, and the recyclable recycling of base material, thus reduced the use amount of log scale, be beneficial to environmental protection.
Preferably, the top layer is PVC decorating film or the PE decorating film that fits in described substrate surface.Better, carry out moulding processing and utilize described PVC decorating film or PE decorating film to carry out veneer or coating at substrate surface.PE is poly English the abbreviation, is a kind of thermoplastic resin that ethene makes through polymerization.PVC decorating film or PE decorating film can well be fitted with the PVC foamed board, thereby allow fan blade surface possess the performance that PVC film or PE film have.
Preferably, the top layer is wooden skin or the metallic film that fits in substrate surface, the various natural veneers of especially can fitting, thus have the texture of plank flabellum.
Preferably, the top layer is the three-dimensional version line that adopts high pressing mold pressurization to form at substrate surface, as imitative wood grain, thereby produces the texture of plank on the PVC foamed board.
Better, in such scheme, oil film printing or water transfer printing or thermal transfer printing can be carried out in the top layer, and water transfer printing and hot transfer printing are all a kind of printingtechniquies, and so-called water transfer printing refers to utilize hydraulic pressure will carry out with the transfer paper/plastic film of multi color pattern a kind of printing of macromolecule hydrolysis; So-called hot transfer printing be with the numerical digit pattern see through table-printing machine with special transfer ink watermark on the transfer printing special-purpose paper, then with special-purpose transfer interpreter, High Temperature High Pressure ground is transferred to the commodity surfaces accurately with pattern, completes commodity and prints.Can print as required various patterns on the top layer, thereby increase the aesthetic feeling of flabellum.
Better, the substrate upper and lower surface is equipped with the top layer in such scheme, as shown in Figure 2, can make fan blade not limit the direction of installation, even can use a period of time that blade is changed direction (face) installation, thereby offset timeliness bending deflection, prevent that the fan blade afterbody is sagging, extend the working life of blade.
Better, the edge of fan blade is provided with chamfered edge (chamfering), the structure that subtracts material namely is set in the edge, make brim-portion thickness relatively smaller, fan blade inclination several angle is installed simultaneously, thereby reduce the suffered resistance of fan blade rotation process, the rotational efficienty that improves fan reduces energy consumption.The chamfered edge position can be that the cross section is the rounding off structure of circular arc, can be also rectilinear chamfering structure.In existing ceiling fan safety standard, decorate under the prerequisite of blade lowest edge thickness limits (3.3mm), with different streamlines plane or curved surface, reduce the thickness of decorating the blade edge, and then improve windage, the air agitation of ceiling fan operation and reach higher motor running efficient.
Preferably, the density of described PVC foamed board is 0.55～0.80g ∕ cm
3, the thickness of described PVC foamed board is 4.6～8.0 millimeters, can adopt with other similar general, engineering plastics is the auxiliary formed PVC foamed board of copolymerization.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the scope that the utility model is contained.
