The working process and principle are as follows: starting the first motor 10 to enable the connecting ring 9 to rotate anticlockwise, feeding the dried semi-finished rice crust into the rice crust screening assembly 3 by the feeding conveying mechanism 1, namely feeding the semi-finished rice crust into the top plate 15 of the clamping mechanism 8 positioned in the twelve-point direction on the connecting ring 9, wherein the special-shaped cam 12 does not move all the time because the special-shaped cam 12 protrudes in the twelve-point and three-point directions of the axis of the special-shaped cam 12, and the special-shaped cam 12 is always abutted against the rollers 19 of the four clamping mechanisms 8, so that the clamping mechanisms 8 positioned in the twelve-point and three-point directions are loosened (the sliding sleeve 16 is squeezed, the sliding sleeve 16 moves in the direction far away from the connecting ring 9 along the connecting rod 14, the first spring 23 is compressed, the supporting disk 17 and the supporting arm 20 are stressed to enable the clamping arm 21 to expand outwards), and the clamping mechanisms 8 positioned in the six-point and nine-point directions are clamped (the sliding sleeve 16 moves towards the center of the connecting ring 9 along the connecting rod 14, the first spring 23 resets, the supporting disc 17 and the supporting arm 20 are stressed to enable the clamping arm 21 to be tightened inwards), when the clamping mechanism 8 located in the twelve-point direction receives the rice crust, the rice crust is conveyed to the nine-point direction anticlockwise, at the moment, if the rice crust edge is seriously damaged, the rice crust drops to one side due to the fact that the clamping arm 21 cannot clamp the rice crust edge, if the rice crust edge is qualified or the goods defect is small, the rice crust continues to move to the six-point direction along with the clamping mechanism 8, and the thermal imaging device 7 judges the surface of the rice crust;

1. if the semi-finished products are qualified, the second motor 31 is started to rotate positively to drive the gear 30 to rotate clockwise, and the gear 30 is meshed with the rack 29, so that the rack 25 of the discharging conveying mechanism 2 is driven to move to the position below the six-point-direction clamping mechanism 8, in the process, the two insert rods 32 are inserted into the two slots 24, and the thickness of the insert rods 32 is gradually increased, so that the insert rods 32 press the bottom ends of the slots 24, the sliding sleeve 16 is forced to be extruded, the sliding sleeve 16 moves towards the direction far away from the connecting ring 9 along the connecting rod 14, the first spring 23 is compressed, the supporting disc 17 and the supporting arm 20 are forced to enable the clamping arm 21 to expand outwards, so that the crispy rice is released, and the qualified crispy rice semi-finished products are conveyed to the frying station through the discharging conveying mechanism 2 by the clamping mechanism 8 located at six points on the connecting ring 9;

2. if the thermal imaging device 7 judges that cracks exist on the surface or the surface has defects, the motor II 31 is not started, the motor I10 is started, and when the clamping mechanism 8 continues to move anticlockwise to three points, the clamping mechanism 8 is loosened, so that unqualified rice crust is loosened and falls to one side, and a containing box can be placed to collect the unqualified rice crust for later use;

when the clamping mechanism 8 moves to the three-point direction, the electromagnet 40 on the clamping mechanism attracts the end part of the metal pipe 37 in the primary sleeve 35, so that the plug 38 is pulled, compressed gas can be blown to the clamping mechanism 8 in the three-point direction from the gas channel 33 through the gas blowing pipe 34 smoothly, chips are blown away, the chips are prevented from being clamped in the abdicating groove 22 and the clamping arm 21 and cannot clamp the rice crust smoothly, when the clamping mechanism 8 moves away from the three-point direction, the metal pipe 37 is not attracted, and under the reset action of the second spring 39, the plug 39 moves and resets, so that the gas flow channel 33 is blocked, and the gas blowing pipe 34 does not blow gas.

The invention can judge whether the rice crust is qualified or not by arranging the thermal imaging device 7 and the four groups of clamping mechanisms 9, qualified rice crusts are conveyed to a frying station through the discharging and conveying mechanism 2, unqualified rice crusts are screened and fall to two sides of the rice crusts screening component 3, the arranged special-shaped cam 12 protrudes along twelve and three points of the axis, the special-shaped cam 12 is always abutted against the rollers 19 of the four clamping mechanisms 8, thus, the gripping mechanisms 8 in the twelve and three point directions are released, while the gripping mechanisms 8 in the six and nine point directions are clamped, so that the rice crust is clamped in the transferring process, unqualified rice crust automatically falls off, and when the rice crust is qualified, since the thickness of the insertion rod 32 is gradually increased, so that the insertion rod 32 presses the bottom end of the insertion groove 24, so that the sliding sleeve 16 is forced to be squeezed, thereby loosening the clamping mechanism 8 positioned at six points on the connecting ring 9;

through being equipped with electro-magnet 40 on sliding sleeve 12, set up airflow channel 33 in grudging post 5 for when fixture 8 moved to three point directions, compressed gas can blow to fixture 8 of three point directions through gas blow pipe 34 smoothly from air channel 33, thereby blows away the piece, and the intermittent type of setting is blown not only saves the air supply and avoids leading to the piece to be the movement of disorder in rice crust screening subassembly 3 all around owing to blowing always, causes whole device.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
