(2) Measuring the length S of the sealing cover, wherein the stroke from the first sensor to the gap is S1, the stroke from the second sensor to the gap is S2, when the soft bag is detected, the stroke from the actual soft bag to the gap matched with the clamping insert is S1+s, the second conveyor belt moves at a constant speed of V2, when the first sensor detects the soft bag, a signal is fed back to the controller to record the current speed V1 and time T1 of the soft bag, when the second sensor detects the clamping insert, the signal is fed back to the controller and record time T2, whether T1-T2 is larger than 0 is judged, and when T1-T2 is larger than or equal to 0, the controller controls the first conveyor belt to change speed to the speed The soft bag mouth is matched with the clamping insert at a clearance; when T1-T2 < 0, the controller controls the first conveyor belt to change speed to/>The soft bag mouth is matched with the clamping insert at a clearance;
(3) The soft bag with the head facing forward is conveyed to the second conveyor belt, and the inverted soft bag falls from a gap between the first conveyor belt and the second conveyor belt;
(4) The soft bags are conveyed to a third conveyor belt through a second conveyor belt, are limited in a limiting cover through an elastic limiting rod after entering the third conveyor belt, and are orderly and equidistantly arranged in the limiting cover;
(5) When the clamping inserts on the fourth conveyor belt pass through the gaps, the clamping inserts are matched with the soft bags on the third conveyor belt, which are positioned at the tail end of the limiting cover, so that the soft bags are transferred to the fourth conveyor belt and conveyed out of the device.
