Like Fig. 2, shown in 3, drying unit 20 comprises: cover body 21; Be arranged on the conveyer 22 in the cover body 21; Be used to make the temperature in the cover body 21 to remain on the heater 23 in the preset range; And the bracing frame 24 that is used to support cover body 21, conveyer 22 and heater 23.Cover body 21 comprises roof 211 and two sidewalls 212, is respectively equipped with inlet 213 and outlet 214 at the two ends of cover body 21.The timber floor 1 that was coated with lacquer 213 is sent into the cover body from entering the mouth, and is transmitted device 22 and transmits to outlet 214 places, leaves cover body 21 from exporting 214 at last.
Conveyer 22 comprises conveyer chain 221 and the sprocket wheel 222 that is used to drive this conveyer chain.Be arranged at intervals with a plurality of supporting plate groups 223 on the conveyer chain 221.The working surface 223a that matches with timber floor of each supporting plate group 223 is obliquely installed with respect to conveyer chain 221, and preferably, inclined angle alpha is 70 °.Preferably, each supporting plate group 223 is made up of at least one supporting plate 224 that is arranged side by side along the direct of travel perpendicular to conveyer chain 221.Fig. 3 shows the example of being made up of supporting plate group 223 two supporting plates 224.The quantity of supporting plate 224 in each supporting plate group 223, and the shape and size of each supporting plate 224 are confirmed according to reality processing needs.
According to one embodiment of the invention, sprocket wheel 222 is driven by the step drive device like the stepper motor (not shown).As shown in Figure 6, in the porch of cover body, be provided with two switches, wherein the first switch s1 with respect to second switch s2 be arranged in producer to upstream side (left side of Fig. 2).When timber floor process switch s1 and s2, corresponding switch can produce triggering signal, thus the duty of control step drive unit.When timber floor 1 during through the first switch s1, the first switch s1 is triggered, and makes stepper motor suspend.At this moment, sprocket wheel 222 stops operating, thereby conveyer chain 221 is static; And the conveyer belt 30 that is arranged on the drying unit upstream side continues to forward timber floor.When timber floor process second switch s2, second switch s2 is triggered, and stepper motor operation drive sprocket 222 rotates.At this moment, a supporting plate group (like the supporting plate group 223I of Fig. 2) that is arranged in conveyer chain 221 ends can upwards be rotated along with advancing of conveyer chain 221, makes the unvarnished surface of its working surface and timber floor (back side) contact, and finally holds up this timber floor.Simultaneously, other timber floor in the cover body 21 under heeling condition with conveyer chain 221 preset distance of advancing.When next piece timber floor during through the first switch s1, stepper motor suspends once more.Repeat said process, can the timber floor of being painted 1 be delivered to drying unit 20 successively via conveyer belt 30.
Should be noted that timber floor keeps flat basically on conveyer belt 30, thereby every timber floor can take relatively large transmission length.Different therewith, timber floor is tilted-putted in drying unit 20, and its inclination angle is corresponding to the inclination alpha (see figure 2) of the working surface of supporting plate group 223, and like this, every timber floor only takies very little drive length.Obviously, for the conveyer chain 221 and the conveyer belt 30 of equal length, can place more timber floor on the conveyer chain 221.Under the prerequisite that the productive temp of productive temp that guarantees drying unit 20 and whole timber floor system of processing S is complementary, the transfer rate of conveyer chain 221 can be set to much smaller than the transfer rate of conveyer belt 30.So, under the prerequisite that guarantees drying time, than prior art, the length of conveyer chain 221 can shorten significantly, thereby reduces the length of whole timber floor system of processing.
When PU lacquer in cover body fully after the drying, timber floor is sent to outlet 214 places.According to one embodiment of present invention, be provided with the pin 25 that is used for top, limit floor translational speed in position near cover body outlet 214.Pin 25 extends setting towards conveyer chain 221, and the one of which end pivoting is connected to cover body 21, and like its roof 211, and the other end is used for matching with the top of timber floor, to limit its translational speed.Preferably, be provided with roller 251 at the other end of pin 25, to avoid scratching the painted surface of timber floor.Between pin 25 and cover body 21, be connected with limit spring 26, be used for pin 25 is held in a predetermined position the position of approximate vertical for example as shown in Figure 2., on cover body roof 211, be fixed with a plumbing bar 217 here, spring 26 is connected between pin 25 and the plumbing bar 217.
According to a preferred embodiment of the invention,, also be provided with from this and export 214 outward extending discharging chains 27, be used to accelerate the translational speed of timber floor 1 bottom 1b in the exit of cover body.The transfer rate of discharging chain 27 is greater than the transfer rate of conveyer chain 221.
Under the restriction of pin 25 and discharging chain 27, advancing to the timber floor that cover body exports 214 places can transfer flat condition to gradually from the inclination laying state.Fig. 7 A to 7D shows this process.
Shown in Fig. 7 A, the top 1a of timber floor 1 is by pin 25 restrictions, and bottom 1b is sent on the discharging chain 27 from conveyer chain 223, and the translational speed of 1b is greater than the translational speed of top 1a bottom making.Thereby 1b's timber floor 1 rotates around its bottom, and its top 1a moves down with respect to pin 25 simultaneously.At this moment, the working surface 223a of the back side of timber floor and supporting plate group is separated, and to gradually near discharging chain 27.After timber floor 1 turned an angle, its top 1a separated with pin 25, shown in Fig. 7 B.At this moment the bottom 1b of timber floor continues to move forward with discharging chain 27, makes timber floor 1 be rotated further, shown in Fig. 7 C.To the last, timber floor 1 keeps flat on the discharging chain 27 fully, shown in Fig. 7 D.At this moment, timber floor 1 utilizes its unvarnished back side to contact with discharging chain 27.
Through pin 25 and discharging chain 27 are set, can avoid timber floor upset suddenly when leaving cover body 21 to make its front that scribbles the PU lacquer photograph on the conveyer belt 30, cause damage.Preferably, discharging chain 27 can be inclined relative to horizontal setting, makes its end near cover body outlet 214 higher, and lower away from an end of cover body outlet 214.Like this, can avoid timber floor in the process of setting level, to bounce carrier chain better.The transfer rate of discharging chain 27 is confirmed according to the speed of conveyer chain 221 and the size of timber floor.According to actual conditions, also can discharging chain 27 only be set and pin 25 is not set, perhaps replace discharging chain 27 greater than the conveyer belt 30 of conveyer chain 221 with transfer rate.
