Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

as shown in figure 1, the feeding device of the powder packaging machine comprises a feeding hopper 1, wherein the top and the bottom of the feeding hopper 1 are respectively provided with a feeding port 2 and a discharging port 3, and the discharging port 3 is provided with an opening and closing plate 4 and an opening and closing switch 5 for driving the opening and closing plate 4 to open and close. As shown in fig. 2, the open-close switch 5 comprises a rotating rod 6 and a spacing switch driving mechanism 7 for driving the rotating rod 6 to rotate, a slide way is arranged on the side wall of the bottom of the feeding hopper 1, the opening plate 4 is arranged by sliding transversely, one end of the opening plate 4 is connected with the side wall of the feeding hopper 1 through an elastic part 8 and can be reset relative to the side wall of the feeding hopper 1 under the action of the elastic part 8, a protruding block 9 is arranged at the bottom of the opening plate 4, the spacing switch driving mechanism 7 is arranged under the protruding block 9, when the rotating rod 6 rotates to be vertical to the opening plate 4 and the end part of the rotating rod faces the opening plate 4, the tip height of dwang 6 is higher than the bottom surface height of protruding piece 9 under this state, and the tip of dwang 6 is equipped with half-circular arc radius angle, and the tip of dwang 6 still is equipped with one through a pivot free rotation and promotes piece 10 that is the square form.

As shown in fig. 2, this figure shows a state in which the opening plate 4 has been pushed a certain distance to the right by the rotating lever 6. At ordinary times, the opening plate 4 can seal the discharge port 3 under the limit of the elastic part 8, after the interval switch driving mechanism 7 is started, the rotating rod 6 realizes periodic rotation, when the rotating rod 6 rotates to the 0-degree position in the schedule, the end part of the rotating rod 6 can be contacted with the convex block 9, then the rotating rod 6 continues to rotate clockwise, because the end part of the rotating rod 6 in the state is higher than the bottom surface height of the convex block 9, the rotating rod 6 can stir the convex block 9 to the right side for a certain distance after continuing to rotate, thereby realizing the right movement of the opening plate 4, leading the discharge port 3 to be in an open state, when the rotating rod 6 continues to rotate to a certain angle, the end part of the rotating rod 6 can be separated from the convex block 9, then the opening plate 4 can complete the reset under the action of the elastic part 8 after losing the restriction of the rotating rod 6, returning to the initial position, and sealing the discharge port 3, then the rotating rod 6 continues to rotate, and at least needs to rotate 270 degrees again to enter the state of next contact with the convex block 9, so that the discharge port 3 is in a closed state within the time and cannot feed materials into subsequent equipment, the subsequent collecting box can have enough time to be replaced in the process, and people only need to control the amount of the materials which can be sent down after the opening of the opening plate 4 in a period, package the amount of the materials and the waiting time after the closing of the opening plate 4, calculate and plan, and then the coordination of all parts of the whole packaging machine equipment can be optimal.

In the whole process, the interval switch driving mechanism 7 is always in an open state, so that the opening and closing of the opening and closing plate 4 at intervals are realized, the interval feeding is completed, the opening or closing of the opening and closing switch 5 is not required to be manually controlled by people, and the using effect is very good.

It is to be understood that in the claims, the specification of the present invention, all "including … …" are to be interpreted in an open-ended manner, i.e. in a manner equivalent to "including at least … …", and not in a closed manner, i.e. in a manner not to be interpreted as "including … … only".
