a negative pressure pipe of a sucking disc (31) of the bag opening mechanism (3) is disconnected, a bag feeding cylinder (22) acts, a sliding frame (23) is sent back to the initial position of the guide shaft (21) to wait for the next bag feeding; the open bag (0) is clamped by a claw clamp (83) of a pneumatic claw (82) and hung below the material port (5);
the bag mouth clamping cylinder (85) acts, a piston rod of the bag mouth clamping cylinder extends to the outer wall of the telescopic material opening (51) to push the clamping sheet (84) to cling to the side wall of the telescopic material opening (51), the bag mouth wall of the open bag (0) is positioned between the clamping sheet (84) and the outer wall of the telescopic material opening (51), the clamping sheet (84) grips the telescopic material opening (51), and the bag mouth of the open bag (0) is pasted to the outer wall of the telescopic material opening (51) and clamped by the clamping sheet (84);
IV, filling
After the step III is finished, a feeding valve on the feeding pipe is opened, and the powder falls into the lower open bag (0) through the fixed material port (52) and the telescopic material port (51); meanwhile, the tray cylinder (45) acts, a piston rod of the tray cylinder extends upwards, and the tray (46) rises to support the bottom of the open bag (0) and support the open bag (0); a weighing sensor (41) at the upper end of the weighing frame (42) sends weight signals of the current weighing frame (42), parts mounted on the weighing frame and the open bag (0) to a control center in real time, and when the weight of the open bag (0) reaches the filling amount set in the control center, the control center closes the feeding valve;
v-shaped holding bag
After the powder is filled, a piston rod of a bag holding cylinder (67) extends out, and a bag holding clamp (62) clamps a bag body of an open bag (0) filled with the powder;
the piston rod of the bag mouth clamping cylinder (85) retracts, the clamping sheet (84) is loosened,
the material port extends out of a piston rod of the air cylinder (53) to retract, the telescopic material port (51) is pulled upwards, and the lower end of the telescopic material port (51) leaves the opening of the open bag (0);
the pneumatic paw (82) opens, and the paw clamp (83) releases the mouth of the bag;
a piston rod of the bag opening clamping strip cylinder (66) extends out, a bag opening is clamped by the bag opening clamping strip (61), and the front side wall and the rear side wall of the bag opening are attached;
at the moment, the bag bottom of the open bag (0) filled with the powder is supported by the tray (46), the bag body is clamped by the bag clamping clip (62), and the bag opening is clamped, flattened and sealed by the bag opening clamping strip (61);
VI transfer
The tray cylinder (45) acts, the piston rod of the tray cylinder retracts, the tray (46) with the open bag (0) thereon descends until the surface of the tray (46) is lower than the bottom surface of the sliding frame (64);
the pushing cylinder (72) acts, a piston rod of the pushing cylinder extends out to push the sliding frame (64), the bag holding frame (63) on the sliding frame and the bag holding clamp (62) to clamp and move the powder-filled open bag (0) to the upper side of the starting end of the conveyor belt (73), the piston rod of the bag holding cylinder (67) retracts, the bag holding clamp (62) releases the bag body of the open bag (0), meanwhile, the piston rod of the bag opening clamping strip cylinder (66) retracts, the bag opening clamping strip (61) releases the bag opening, and the open bag (0) is placed on the conveyor belt (73);
VII, transmitting
The conveyor belt (73) moves, and the opened bag (0) filled with the powder is sent to the next step.
8. The method of operating an open-pocket bag feeding machine according to claim 7, characterized in that:
a cylinder body of a bag pulling cylinder (86) is respectively fixed on the left side and the right side of the fixed material port (52), a piston rod of the bag pulling cylinder (86) is horizontal and extends to the left side and the right side of the fixed material port (52), a connecting frame (87) is fixed at the top end of the piston rod of the bag pulling cylinder (86), and the cylinder body of the paw opening and closing cylinder (81) is fixed on the connecting frame (87);
when the step II is carried out, a piston rod of the bag pulling cylinder (86) is in a retraction state, and the distance between the claw clamps (83) of the pneumatic claws (82) at the left side and the right side is smaller than the width of the opening of the open bag (0) and larger than the maximum width of the telescopic material opening (51); in the step V, when the material opening extends out of a piston rod of the air cylinder (53) and retracts, the telescopic material opening (51) is pulled upwards, after the lower end of the telescopic material opening (51) leaves the opening of the open bag (0), a piston rod of the bag pulling air cylinder (86) extends out to the left and right outer sides of the fixed material opening (52), so that the pneumatic claw (82) below the connecting frame (89) clamps two ends of the opening and moves outwards, and the opening of the open bag (0) is pulled flat; then the pneumatic paw (82) opens and the paw clamp (83) releases the bag mouth.
9. The method of operating an open-pocket bag feeding machine according to claim 7, characterized in that:
bag body guide plates (74) are fixed on two sides of the conveyor belt (73), and the plate surfaces of the bag body guide plates (74) on the two sides are vertically opposite; bag mouth guide plates (75) are further fixed on two sides of the conveyor belt (73), and the plate surfaces of the bag mouth guide plates (75) on the two sides are vertically opposite;
