Abstract
The utility model discloses an improved structure for an evaporation boat system of an aluminizing machine. The improved structure comprises a cooling roller and a heating body arranged below the cooling roller; one or a plurality of rows of grooves for accommodating evaporation boat ceramic chips are arranged on an upper plane of the heating body; an aluminum wire conveying device for conveying aluminum wires is arranged between the cooling roller and the evaporation boat ceramic chips; and a plurality of holes are formed around the evaporation boat ceramic chips positioned at two ends of the heating body. In the improved structure, the plurality of holes are formed around the evaporation boat ceramic chips positioned at the two ends of the heating body, and cross sections of accessories in the range of the evaporation boat ceramic chips positioned at the two ends of the heating body are reduced and the resistivity is increased, so the evaporation boat ceramic chips positioned at the two ends are relatively highly heated; therefore, the thickness of aluminum layers at two ends of an aluminized film is uniform with that of the middle part.
Description
Technical field
The utility model relates to a kind of aluminum-spraying machine and evaporates boat system improvement structure.
Background technology
The aluminum-spraying machine principle be vacuum environment under, by electrically heated evaporation boat ceramic plate, the evaporation aluminium wire is run into aluminium steam on the face, forms the very thin aluminium lamination that has metalluster and mirror effect of one deck, this technology is widely used in the packaging industry.The conventional general every group of ceramic plate of aluminum-spraying machine evaporation boat system all adopted logical identical width, length and thickness.But, because first ceramic evaporation sheet and last root ceramic evaporation sheet are owing at the two ends of machine, can not get enough heat heating usually, so temperature is on the low side, cause a part of aluminium steam upwards not evaporate, the uneven situation of aluminium plating film two ends aluminum layer thickness occurs.
The utility model content
Technical problem to be solved in the utility model just provides a kind of aluminum-spraying machine and evaporates boat system improvement structure, can make the aluminium plating film aluminum layer thickness that plates out even.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: aluminum-spraying machine evaporation boat system improves structure, comprise cooling roller and be located at the heating member of cooling roller below, the plane is provided with a row or multi-row groove to hold evaporation boat ceramic plate on the heating member, be provided with the aluminium wire e Foerderanlage and carry aluminium wire between cooling roller and evaporation boat ceramic plate, it is characterized in that: described heating member is provided with several holes around the evaporation boat ceramic plate at two ends.
As preferably, the evaporation boat ceramic plate left and right sides at two ends is located in described hole.
Heating member is provided with several holes in the utility model around the evaporation boat ceramic plate at two ends, because heating member reduces at the transversal section of the evaporation boat ceramic plate zone at two ends annex, resistivity increases, then the evaporation boat ceramic plate at two ends obtains higher heating, makes aluminium plating film two ends aluminum layer thickness and middle portion uniformity.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the heating member structural representation;
Embodiment
Follow shown in Figure 2 as Fig. 1, improve the embodiment of structure for a kind of aluminum-spraying machine evaporation of the utility model boat system, comprise cooling roller 2 and be located at the heating member 5 of cooling roller below, the plane is provided with a row or multi-row groove to hold evaporation boat ceramic plate 6 on the heating member, be provided with aluminium wire e Foerderanlage 3 and carry aluminium wire 4 between cooling roller and evaporation boat ceramic plate, described heating member is provided with several holes 51 around the evaporation boat ceramic plate at two ends.Evaporation boat ceramic plate 6 left and right sides at two ends are located in described hole 51, and are that centrosymmetry distributes with evaporation boat ceramic plate planar medullary ray, and every limit is provided with three holes 51.
Can certainly adopt another kind of mode, aluminium wire in the aluminium wire e Foerderanlage is divided into the end segments at two ends and the interlude at middle part, the interlude aluminium wire is between polyline shaped and broken line angle and equates, the end segments aluminium wire is vertical with the aluminium wire throughput direction, wherein the angle angle of end segments aluminium wire 41 and adjacent interlude aluminium wire 42 be between intermediate ends aluminium wire broken line the angle angle 1/2nd.The diameter of described aluminium wire e Foerderanlage medial end portions section aluminium wire is greater than interlude aluminium wire diameter.Aluminium plating film 1 is located on the cooling roller, and heating member heating evaporation boat ceramic plate is also run into aluminium steam on the aluminium plating film face aluminium wire generation aluminium steam 7 of its top.
Under vacuum environment, aluminium steam is to have the free diffusion motion of molecule to cause attached to this process on the aluminium plating film at last, the local diffusion motion that concentration is high more is fast more, therefore, when the evaporation aluminium wire, want aluminium plating film and keep evenly, the aluminium vapour concentration of evaporating on the evaporation boat under will making is consistent.Aluminium plating film intermediary aluminium lamination by under interlude aluminium wire evaporation form, this and have only a radicle section aluminium wire to provide aluminium steam variant at two ends, thereby it is inhomogeneous to cause two ends to be aluminized.Therefore, the angle angle modification of end segments aluminium wire and adjacent interlude aluminium wire for being 1/2nd of angle angle between intermediate ends aluminium wire broken line, so just can be guaranteed the aluminium steam of a comparison of formation uniform concentration when the face of row's evaporation boat ceramic plate.
The diameter account form of end segments aluminium wire is that the heat of calculating the heating of two ends evaporation boat is poor, revises the diameter of carrying aluminium wire, to two ends evaporation aluminium steam dosage.Because aluminum-spraying machine aluminium wire e Foerderanlage adopts synchronization conveying device usually, therefore can't change the speed of two ends wire feed.Therefore, revise the diameter of two ends aluminium wire, realize the purpose of dosage.As, heating member is under 350 amperes current flow heats, and it is little about 50 amperes that the heating current at two ends is wanted, and according to calculating the diameter of aluminium wire is modified to 1.7mm by normal 1.5mm, reaches consistent in the middle of the uniformity coefficient two ends of aluminium plating film aluminium lamination substantially.The formula that calculates is:
UΔV＝VρC＝2πl(Δd/4)
2ρC
U-voltage Δ V-difference electric current ρ-aluminium wire density C-aluminum metal evaporite ratio thermal capacitance
L-wire feed rate Δ d-revises diameter
