In this embodiment, the tongue plate 29 is narrow at the top and wide at the bottom, and the width at the bottom is smaller than the width at the middle but larger than the width at the top. The blowing nozzle 27 is disposed in a perpendicular relationship to the tongue plate 29. Little hopper 17 side fixed bolster 28, the lower part of support 28 is fixed with bracket 26 towards little hopper 23 side, and the lower part of support 28 is the fixed cylinder 24 that opens the door of little hopper side dorsad, striker plate 25 is located bracket 26 upper surface and is connected fixedly with the jar pole of cylinder 24 that opens the door, be equipped with on the bracket 26 and correspond the little hopper discharge opening avoid the mouth. The rear side surface of the upper part of the small hopper 23 is provided with a feeding hole, the rear side surface of the small hopper is provided with a left fixing plate 18 and a right fixing plate 16 on two sides of the feeding hole, a pressing cylinder 10 is fixed on the pressing plate 20, a cylinder seat 11 of the pressing cylinder is fixedly connected with the pressing plate 20 through screws, a pressing head 9 for extruding the right fixing plate 16 is fixed at the end part of a cylinder rod of the pressing cylinder 10 through screws, and a positioning wedge block 19 is arranged at the position of the pressing plate 20 corresponding to the left fixing plate 18. The compacting cylinder 10 pushes the small hopper to the side of the positioning wedge block through the pressure head due to the action of compressed air, and the positioning wedge block 19 and the left fixing plate 18 are wedged mutually to complete the fixing of the small hopper 23. The swing cylinder component comprises a tailstock 22 fixed on the frame 3 through screw connection, a swing cylinder 7 hinged with the tailstock 22 through a pin shaft, and a swing arm 21 hinged with the end part of a cylinder rod of the swing cylinder 7 through a pin shaft, and the other end of the swing arm 21 is connected with the rotating shaft 4 in a key mode. Frame 3 corresponds 2 anterior oblique below positions of conveyer belt and is equipped with material receiving mouth 6, and material receiving mouth 6 is the bucket form, and below opening orientation automatic weighing feeding system's weighing device. The driving device comprises a servo motor 14 and a speed reducer 13 connected with the servo motor 14, a driving roller 15 is fixed on the frame 3 through a bearing and is connected with the speed reducer 13, and the speed reducer 13 is fixedly connected with the frame 3 through a motor base 12. In this embodiment, the driving device and the swing cylinder assembly are respectively disposed on both sides of the frame 3.

The working principle is as follows:

referring to fig. 4, in the feeding state of the conveying belt, the servo motor 14 drives the driving roller 15 to rotate through the reducer 13, the conveying belt 2 is driven to rotate through friction force, so that the material is conveyed downwards from the conveying belt, the receiving hopper 17 on the pressing plate 20 is in a vertical state of the pressing plate and is very close to the conveying belt, so that part of the material on the conveying belt 2 can fall into the receiving hopper 17 and flow into the small hopper 23, the rest of the material falls into the weighing device through the receiving port 6 below, when only 200g of the material and the set target value in the weighing device are left, the swing cylinder 7 drives the rotating shaft 4 to rotate through the swing arm 21, so as to drive the pressing plate 20 to lean against the conveying belt 2, referring to fig. 5, at this moment, the conveying belt 2 stops, the door opening cylinder 24 drives the material baffle plate 25 to be far away from the discharge port of the small hopper 23, simultaneously the vibrator 8 vibrates, the air blowing nozzle 27 blows air to make the material fall from the small hopper 23, the material receiving opening 6 falls into the weighing device, when the weight reaches a target value, the vibrator 8 and the blowing nozzle 27 stop working, and the door opening cylinder 24 drives the material baffle plate 25 to move reversely to block the discharge opening of the small hopper 23.

In the process, the amplitude of the tongue-shaped plate 29 at the lower part of the small hopper is different from that of the small hopper main body when the vibrator 8 vibrates, the amplitude of the tongue-shaped plate 29 is larger than that of the small hopper main body, the tongue-shaped plate 29 breaks up the materials in the small hopper 23, and the blowing nozzle 27 blows air to blow the materials in the small hopper 23 to be fluffy, so that the materials are prevented from being adhered to the inner wall of the small hopper, and the materials are more easily dropped from the small hopper 23. A small amount of materials can overflow from the slit 30 of the small hopper due to vibration, but all the materials finally fall on the weighing device, and the metering and feeding are not influenced.

The embodiments of the present invention have been described in detail, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should be covered by the present patent.
