By positioning cup 19 it is possible to prevente effectively from piston is toppled over.
Further, as shown in figure 4, as it can be seen that spreading all over air hole on positioning cup 19, in favor of hot wind entrance, realization in figure
It is more efficient dry.
In order to facilitate the push-in of stoving rack 10, as shown in figure 4, the back side of the plate body 17 in stoving rack 10, i.e. stoving rack 10
Lower face on four castors 20 are installed, each side have a pair in stoving rack 10, so that in stoving rack 10 to babinet
During interior push, friction can be reduced.
In addition, stoving rack 10, can be supported certain altitude, be conducive to the arrangement of pallet 12 by the presence of castor 20.
Further, as previously described, because the presence of leading screw 6, in order to avoid stoving rack 10 is done when being pushed into babinet
Relate to, U-type groove 18 is provided with stoving rack 10, U-type groove 18 is unsuitable wide, otherwise can influence stoving rack 10 and determine on pallet 12
Position, therefore, it is necessary to ensure the proper alignment of U-type groove 18 and leading screw 6 under conditions of 18 relative narrower of U-type groove, therefore, in Fig. 3
In shown structure, track 15 is equipped with bottom plate 11, to be oriented to castor 20, so that beneficial to stoving rack 10 in push-in case
Positioning during body.
In Fig. 1, a stent 7 is additionally provided with babinet, stent 7 is mainly used in the presence of improving multiple stoving racks 10,
Mitigate the load of leading screw 6, stage of mitigation is drying stage, rather than the loading and unloading stage, and stent 7 can be in drying stage
Most of load transfer comes, so as to reduce the damage to leading screw 6.
In view of this, the stent 7 has multilayer, the number of plies fewer than the quantity of stoving rack 10 one, positioned at nethermost drying
Frame 10 can be supported directly by bottom plate 11.
