Detailed description of the invention
As shown in Figure 1, drying unit, comprise heating arrangements, heating arrangements is made up of some segments combined infrared drying stoves 3, and in word order, charging place of infrared drying stove 3 and discharging place are respectively arranged with roller feeding device 1 and roller drawing mechanism 4, are provided with guipure feeding device 2 between charging place of roller feeding device 1 and infrared drying stove 3, are provided with guipure drawing mechanism 5 between discharging place of roller drawing mechanism 4 and infrared drying stove 3.As shown in Figure 2, infrared drying stove 3 comprises infrared lamp group 34, infrared lamp group 34 hangs in the furnace chamber of infrared drying stove 3, the below of infrared lamp group 34 is provided with delivery platform 31, the blower fan 33 that motor drives is provided with in the furnace chamber of the infrared drying stove 3 of the side, bottom of delivery platform 31, blower fan 33 is connected with infrared lamp group 34, and the bottom of infrared drying stove 3 is communicated with lower blower fan 32, and the top of infrared drying stove 3 is communicated with fan 35.
The inside of infrared drying stove 3 adopts hot air circulation, and lower blower fan 32 is blown into a small amount of dry cold wind, and humid air is taken away by fan 35, and the humidity maintained in furnace chamber is not high, and upper and lower compressor flow is little, reduces less to die cavity temperature.
As shown in Figure 3, roller feeding device 1 is identical device with roller drawing mechanism 4, and includes frame 11, frame 11 is provided with some row's rollers 12, and arrangement of staggering between adjacent two rows, roller 12 drives with motor and is connected.Accept (product being about to conveying) using the stagger mode of arrangement of many row's rollers 12; owing to being artificial placement time product is placed; always have a place and first touch conveyor surface; use roller 12 effectively can avoid the collision of product sharp parts and conveyor surface; increase the service life of structure for conveying; also can protect product simultaneously, to avoid damage.Adjacent two row's scroll wheel positions stagger arrangement, decrease the quantity of roller, saving equipment cost when not affecting conveying capacity as far as possible.
Roller drawing mechanism 4 is adopted equally in discharging place of infrared drying stove 3, make heat radiation faster, use aerofoil fan directly to cool product in the bottom of roller drawing mechanism 4, air quantity is large, noise is little, product surface temperature after this section is reduced to less than 30 degree, and shipment of can directly packing, reduces costs.
As shown in Figure 4, guipure feeding device 2 is identical device with guipure drawing mechanism 5, and includes lead frame 21, lead frame 21 is provided with follower rollers 22, closes on follower rollers 22 place and be provided with deviation correcting device 23 in lead frame 21.
As shown in Figure 6, deviation correcting device 23 is made up of installation base plate 24, cylinder 26 and cylinder 25, and cylinder 26 is installed on installation base plate 24, and cylinder 26 drives with cylinder 25 and is connected.Cylinder 26 uses Teflon guipure, can be high temperature resistant and the life-span is permanent.
As shown in Figure 5, infrared lamp group 34 comprises infrared lamp 37 and some groups of lamp panels 36, and infrared lamp 37 tilts, interval is thrown on single lamp panel 36 in order, and the infrared lamp 37 on adjacent lamp panel 36 is thrown on single lamp panel 37 in the other direction.
Infrared lamp 37 on adjacent lamp panel 36 is thrown on single lamp panel 37 in the other direction, ensures that to the whole radiation heating process of LGP product be all uniform, there is not radiation blind spot, makes it fully dry and evenly, reduces equipment cost, increase economic efficiency.
The material of the fluorescent tube of infrared lamp 37 is micro-crystalline ceramic glass, further filters the lamp luminescence of infrared lamp 37, and the light of its near-infrared band can be passed through, and all the other light are significantly filtered.
During embody rule, by roller feeding device 1 transfer system, target product is carried along predetermined circuit, through knockdown infrared drying stove 3, accept near infrared radiation heating, moisture is rapidly heated rear evaporation, air circulating system in the furnace chamber of simultaneously infrared drying stove 3 remains that interior humidity is at certain level, unnecessary steam is pulled away, there will not be vapo(u)rous and reduce the situation of drying efficiency, again the mode of the aerofoil fan blowing of product on roller drawing mechanism 4 is cooled fast after drying completes, eliminate unnecessary electrostatic simultaneously, directly packaging can be added up after product discharge.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
