[0039] The outer wall of the bottom of the storage hopper of the screw feeder 9 is provided with a photoelectric switch and an alarm, which is convenient for detecting the amount of rice in the storage hopper of the screw feeder 9 and providing an alarm prompt.

[0040] It should be noted that the present invention is a fully automatic rice quantitative packaging equipment, which places the bag on the support frame 1, and arranges the bag through the longitudinal tidying mechanism 3 and the transverse tidying mechanism 4, and drives the screw rod 33 to move through the driving motor 31, so that the ball nut 34 drives the extrusion rod 35 to move, and extrude the bag laterally to arrange the bag, so that the bag is neatly stacked together, which is convenient for subsequent precise operation. After the bag is placed, the placing platform 2 is moved to the bottom of the U-shaped plate 7 through the second screw displacement mechanism 5, and the first electric telescopic rod 81 of the upper adsorption mechanism 8 is pressed down so that the suction cup is squeezed into contact with the upper surface of the bag, and the first vacuum pump 83 works to create a vacuum in the suction cup to suck up the bag, and the electric telescopic rod returns to its original position. At this time, the first The screw displacement mechanism 6 works, driving the plate body 141 to move to the inner cavity of the U-shaped plate 7 and to be located below the sucked bag body. The lower surface of the bag body is squeezed and contacted with the upper surface of the plate body 141 through the first electric telescopic rod 81.

The bag body is clamped by the electric slider 131 The rice is transported to the inner cavity of the support plate 11 and the clamping plate is rotated by the motor 135 so that the opening of the bag body is located just below the discharge port of the accommodating cylinder 19, and the rice in the storage box 101 enters the accommodating cylinder 19 through the discharge port. Since the entire weight of the accommodating cylinder 19 acts on the weighing scale 20, the weighing scale 20 can quantitatively load the rice. When the rice reaches a certain amount, the valve on the discharge port of the storage box 101 is automatically closed, and the opening of the valve at the discharge port of the accommodating cylinder 19 allows the rice to enter the bag body through the bag opening. When the rice is loaded, the third screw displacement mechanism 16 on the conveyor belt 15 moves, so that the bag body is located between the two sets of cross bars, and the clamping plate moves 134 through the third electric telescopic rod so that the clamping plate fixes the bag body. The bag is released, so that the bag filled with rice falls onto the conveyor belt 15, and is laterally supported and guided by the crossbar (the distance between the two sets of crossbars can be adjusted by the electric telescopic rod) so that the bag enters the bag sewing machine 17 for sewing operation, and is then conveyed out by the conveyor belt 15. A light receiver 103 and a light transmitter 102 are symmetrically arranged on the outer wall of the bottom of the storage box 101. The two constitute a photoelectric switch that can detect the amount in the storage box 101. When the amount of rice is detected to be too little, the material can be loaded through the screw feeder 9, and a photoelectric switch and an alarm are arranged on the outer wall of the bottom of the storage hopper of the screw feeder 9. When the photoelectric switch detects that the amount of rice in the storage hopper of the screw feeder 9 is too little, the alarm can be used to give an alarm prompt to the staff.All electrical equipment in the entire equipment is electrically connected to the PLC control box, and the programmed automatic operation of each electrical equipment is controlled by the PLC control circuit.
