Described FPC enters after described conveying device, in described cooling air unit, dries up, then output after drying in described hot air apparatus.
Preferably, in described rotating shaft, be provided with motor and gear, described motor-driven gear, described gear is for rotating shaft described in transmission.
Compared with prior art, its advantage is, in the present invention, adopts a pair of gear of motor-driven, gear drive rotating shaft, and rotating shaft driving conveying belt, is conducive to improve the connectivity of transmission.Front end is as the entrance that enters FPC, and middle front portion is cold air knife drying section, and middle rear portion is hot blast cutter drying section, and rear end, as the outlet of flexible board, is conducive to accelerate being dried FPC like this.Because of in the middle of two caterpillar conveyer belts, leave suitable gap, make the FPC of the thinner or little layout of Thickness Ratio, reach can dry, do not wander off again, not give a discount, without the effect of impression.
Upper and lower two conveyer belts are by adjusting belt tension mechanism, adjust left end or the right-hand member of rotating shaft, move forward or backward, make upper and lower conveyer belt keep certain tension force, and eliminate the phenomenon that wanders off, and it is to contain polytetrafluoroethylmaterial material that the present invention adopts polytetrafluoroethylene (PTFE) lattice conveyer, polytetrafluoroethylene (PTFE) conveyer belt is connected with rotating shaft, because being horizontal transmission, product crosses plate, with driving polytetrafluoroethylene (PTFE) conveyer belt, fulfil in the form of a ring band for upper and lower two, synchronous rotation, in the middle of upper and lower two conveyer belts, leave suitable gap, in prior art, its air knife knife-edge part of drying system of general delivery wheel is provided with an easy clamp in gap, particularly thinner plate is gone in the more difficult transmission of air knife knife-edge part, during clamp, can cause mill to spend golden face, surface tear, give a discount, and with its air knife edge of a knife of transmission of polytetrafluoroethylene (PTFE) lattice conveyer in conveyer belt outside, there is not gap, product can clamp.And then the surface of the FPC of thinner to Thickness Ratio in course of conveying or little layout is played a protective role, and avoid mill to spend the quality problem such as golden face, surface tear, discounting, impression, improved the effect and quality that FPC is dried.
And, the present invention adopts air-cooler, by flexible pipe, be connected with cold wind cutter, blowing cold air, moisture FPC is positive, the back side is thrown out, afterwards with air-heater, connect electric heater, connecting hose and hot blast cutter, blow out hot blast, by the surface of FPC, the moisture at the back side is thoroughly dried, and has prevented the oxidation of FPC face.
Preferably, described air-heater flexible pipe top is provided with for hot blast being collected to the thermal-arrest wind dish of backheat blower fan.
The present invention further adopts above feature, and its advantage is, the setting of thermal-arrest wind dish, and connecting hose, to the air inlet of air-heater, is used Cycling hot-blast heating, reaches energy-conservation object.
Preferably, the humid air outlet that described hot blast cutter side is provided with, for discharging the air with moisture.
The present invention further adopts above feature, and its advantage is, the setting of humid air outlet, with the air of moisture, is discharged and can be discharged the moisture air in native system from humid air outlet, has further guaranteed the dry of drying system inside.
Preferably, described conveying device is selected to adopt with at least one in the square and network of through hole.
Preferably, the described cold wind cutter in the conveyer belt of described upper strata and the edge of a knife of described hot blast cutter arrange downwards; In described layer conveyer belt, the edge of a knife of cold wind cutter and hot blast cutter upwards arranges.Preferably, described cold wind cutter or hot blast cutter are arranged between the upper and lower transmission plane of described upper conveyor belt, and between the upper and lower transmission plane of described lower conveyer belt.
Two polytetrafluoroethylene (PTFE) lattice conveyers up and down that the present invention adopts, it is woven into the square or through hole network of through hole.A conveyer belt in the above, the edge of a knife of the cold wind cutter of installation is downward, and the edge of a knife of the hot blast cutter of installation is downward, by the through hole grid on conveyer belt, to positive blast-cold on FPC, hot blast; Upwards, the air knife mouth of the hot blast cutter of installation makes progress the air knife mouth of the cold wind cutter of installing at next conveyer belt, by the through hole grid on conveyer belt, to the blast-cold of the FPC back side, hot blast.But because junction is not the position of the air knife edge of a knife, the transmission problems such as clamp can not caused in gap.Make like this together with hot blast can not blow to cold wind, to be more conducive to improve the efficiency that wiring board is dried.
