600 prepare;
(7), when the chunk glass in cullet returnable 140 will more to rafting, car will be raftinged it is placed on container
The lower section of material mouth 147, with the bin gate handle 246 pulled out on container discharge door 146, rafting in cullet returnable 140
Chunk glass.Bin gate handle 246 is unclamped, under the accumulation of energy counter-force effect of container bin gate spring 145, container discharge door 146 can be tight
Container discharge mouth 147 is tightly touched, does not allow chunk glass to scatter.
2nd, the substantive distinguishing features of the above-mentioned protrusion of the present invention, it is ensured that following significant progressive effect can be brought:
(1), worm-and-wheel gear drives test platen 190 that structure setting may be reversed, and is easy to remove chunk glass removing,
It is equipped with cullet returnable 140, it is ensured that chunk glass does not scatter, and worm-and-wheel gear combined support block 202 holds test
Lower plane after platen 190, with reference to the lock pin crank handle 187 of both sides, by means of stud lock pin 189 and the endoporus spiral shell of lock pin bearing 180
Line is engaged so that the cylinder bulb 199 of the termination of stud lock pin 189 enters in the spiral shell cone column lockhole 198 of test platen 190 both sides
Locking positioning, overcoming travelling gear 161 and the cooperation of manual gear 151 does not have the defects of self-locking so that the tempering entirely tested
Firm is kept during glass plate 600.
(2) container bin gate spring 145, is set respectively between lower draw-bar 149 before bin gate hook 245 and the container of both sides, really
Container discharge mouth 147 can tightly be touched by protecting container discharge door 146, not allow chunk glass to scatter.
(3) clamp portion one end and overlap joint, are located at using coplanar V-groove Anchor plate kit 500, particularly sliding part
The plane on clamp portion, and described sliding lower plane 561 is in sustained height with plane 516 on described pressing plate, it is ensured that
The tested surrounding of armorplate glass 600 is in same plane and fixed, discontinuity.
(4), per being to be slidably matched between the V-type protruding rail 541 of side pressing plate and adjacent V-type groove 514, realize to difference
The armorplate glass 600 of specification continuously can be adjusted arbitrarily.
(5), the angle on described pressing plate slope 515 and pressing plate between plane 516 is 51-53 degree, and described pressure
The rubber tabletting 551 of one layer of 2.1-2.3 millimeters thick is bonded with plate slope 515, armorplate glass 600 is entered in adjustment width
While row plane is spacing, a downward component can be produced so that tested armorplate glass 600 touch test platen
