Description
The present invention relates to a kind of lacquer class coating oven that utilizes near-infrared lamp tube that drying source is provided, mainly lying in body of heater one side or two sides and bottom settles number row near-infrared lamp tube to form the high-temperature region, and between two bank light pipes, keep suitably apart from forming low-temperature space, Drawing upon near infrared ray wavelength is short, penetration power is strong, the characteristic that temperature rise is fast, make work package behind the japanning through the Fast Heating drying of high-temperature region and the abirritation of low-temperature space for several times, prevented the quality of heat damage work lacquer, and then more promote the quality of work lacquer, save the working time, and can shorten body of heater length.
At present, the lacquer class coating oven of employing in the production is broadly divided into three kinds:
A, Electric roaster;
B, coal gas baking oven;
C, in, far-infrared roasting oven;
And wherein Electric roaster and coal gas baking oven, because of consideration based on application quality, security and cost, less use, and in, far-infrared roasting oven, can be described as at present comparatively advanced person's equipment, wherein be with in, the far infrared fluorescent tube equidistantly is arranged in one or both sides in the body of heater, yet in, far infrared is longer because of its wavelength, and is so its penetrability is not good, more low and slow because of temperature rise again, can't make the coating heat drying on the work package in short time, cause and produce following shortcoming:
1. temperature rise is lower, so need the lengthening body of heater, prolong stoving time, and lacquer painting is exposed to for a long time in the stove, often causes lacquer painting overheated, and produces skinning.
2. penetrability is not good, cause table, the nexine coating temperature difference of being heated very big, easily make the solvent evaporates time and the top layer of liquid coating nexine too wide in the gap, cause baking later stage lacquer painting to produce pin hole (Pin Hole), or the swell increment that causes in powder coating table, the nexine hardening process differs too big, causes baking later stage lacquer painting to produce wrinkle (Wrinkle).
3. stoving time increases, and not only increases grid electricity fee cost, and the attached outstanding lacquer painting probability of particulate increases in the air.
4. the body of heater lengthening will make the factory building utilization rate reduce.
5. in, a little less than slow, the penetrability of the temperature rise of far infrared, easily make the baking of work package recess coating form the dead angle.
If in will having now, the used fluorescent tube of far-infrared roasting oven replaces to near-infrared lamp tube to improve baking speed, then will produce following two kinds of extreme variations because of the fast characteristic of its temperature rise:
1. as desire to make coating table, lining bone dry on the work package, and routinely straight line is heated fast, then because of the temperature of near infrared ray generations far beyond in, far infrared be height, the easier lacquer painting generation superheating phenomenon that makes.
2. as desire to prevent that lacquer painting is overheated and shorten stoving time, the then easier lacquer painting that makes produces pin hole or wrinkle.
Its wavelength of near infrared ray is short, has preferable penetration power, and the quick characteristic of temperature rise, and it is used in the present invention, can fill part its effectiveness of performance.
For this reason, specialized designs of the present invention a kind of lacquer class coating oven that utilizes near infrared ray that drying source is provided, in the hope of improving aforesaid drawbacks.
The present invention's main purpose is a characteristic of utilizing the near infrared ray temperature rise fast, provides a kind of work package that makes to coat the lacquer class coating oven of rapid draing.
Another object of the present invention is a characteristic of utilizing the near infrared ray penetration power strong, and the lacquer class coating oven of the generation at a kind of minimizing lacquer painting pin hole or wrinkle and baking dead angle is provided.
The present invention's a purpose again is a characteristic of utilizing near infrared ray wavelength weak point, makes the arrangement of near-infrared lamp tube form high and low warm area, provides a kind of minimizing lacquer painting the overheated and lacquer class coating oven of skinning.
The present invention's another purpose is that a kind of lacquer class coating oven that shortens body of heater length is provided.
The present invention has following advantage, and produces the value that goes up:
1. temperature rise speed is fast, work package can rapid warm raising to the required temperature of coating bone dry, so speed of production is fast, electric power province, and can reduce in the air the attached work of particulate in the probability of lacquer painting.
2. the thermal source penetration power that is adopted is strong, makes in the work package table to be heated simultaneously, avoids the generation at lacquer painting pin hole or wrinkle and baking dead angle.
3. the design of high and low warm area prevents the phenomenon of the overheated skinning of lacquer painting, impels in the outstanding lacquer table drying time more aligned, increases the close outstanding power of coating.
4. because of heating rapidly, ratio shortens body of heater length according to this, reduces stoving time, increases the utilization rate in factory building space.
Fig. 1 is a generalized section of the present invention.
Fig. 2 is a work schematic diagram of the present invention.
Conjunction with figs. is existing as follows with the detailed description of the invention:
See also Fig. 1, the present invention lies in a side in the body of heater (1), being provided with number row is arranged by some near-infrared lamp tubes (2), or the number row who is provided with symmetrically in both sides is arranged by some near-infrared lamp tubes (2), or in both sides and the bottom be provided with symmetrical number row and arrange the high-temperature region (3) that forms by some near-infrared lamp tubes (2), will keep somewhere suitably apart from formation low-temperature space (4) between adjacent two row's near-infrared lamp tubes (2) again.
See also Fig. 2, when the work package (5) of work lacquer back enters in the body of heater (1), at first pass through low-temperature space (4) work package (5) is gone ahead of the rest preheating again by high-temperature region (3), the near-infrared lamp tube in this district (2) is because temperature rise is fast and concentrated, rapidly work package (5) ecto-entad is directly heated, the temperature straight line is risen, strong because of the near infrared ray penetration power in addition, cause the base material of work package (5), because of heat is given birth in intermolecular strong vibration, this effect can make the coating table, the heating temperature gap of nexine is dwindled, make the liquid coating table, the volatilization time ratio of nexine solvent is generally more aligned, reduces pin hole and produces, and also can avoid toasting the dead angle, also can make the powder coating table, nexine fusion and sclerosis (plasticizing) lead time is littler, avoids the generation of wrinkle.And the rapid straight line of temperature of back work package (5) lacquer painting of heating rises, and then by low-temperature space (4), because of its wavelength weak point of near infrared ray, thermal radiation range is little, and low-temperature space (4) is not established near-infrared lamp tube (2), thus in this district the heating power of mat air transmitted is only arranged, and do not have the directly effectiveness of heating, its temperature shows higher warm area (3) for low, and is designed to be lower than the temperature that used coating can reach sclerosis (plasticizing).The temperature of work package this moment (5) becomes slowly to rise, and uses to adjust coating table, nexine solvent evaporates or fusion hard (moulding) and change the time difference that cooperatively interacts, thereby makes in the coating table degree of drying more aligned.Work package (5) is finished through the some high and low warm area that designs on demand in advance once more after by low-temperature space (4) and is continued to heat, and finally finishes the step of quick baking.
