[0027] like Figure 1-6 As shown, a weighing and feeding device includes a frame 1 and an electric control box. The frame 1 is provided with a weighing and feeding mechanism 3, which is used to measure the material in the weighing and feeding mechanism 3 and quantitatively feed the material in the weighing and feeding mechanism 3 according to a set value. The weighing and feeding mechanism 3 includes a mounting seat 31 connected to the frame 1, at least one weighing sensor is provided between the mounting seat 31 and the frame 1, an electromagnet 32 ​​is fixedly provided at one end of the mounting seat 31, and an armature assembly 33 is provided at one side of the electromagnet 32.

[0028] The armature assembly 33 is connected to a feeding channel 34. At least one set of spring leaves 35 is provided between the feeding channel 34 and the mounting seat 31. The spring leaves 35 can be made of carbon fiber spring leaves or steel spring leaves. Specifically, two or three sets of spring leaves 35 can be provided between the feeding channel 34 and the first mounting seat 31 to facilitate faster resetting of the feeding channel 34, which is suitable for weighing and feeding heavier materials. A storage bin 36 is connected to the top of one end of the feeding channel 34 close to the armature assembly 33, and a discharge port 37 is provided at the other end.

[0029] Furthermore, the armature assembly 33 includes an armature 331 and at least one screw 332 fixedly connected to the armature 331. An armature connector 333 is sleeved on one end of the screw 332 away from the armature 331. The armature connector 333 and the screw 332 are fixed by an adjusting nut. The feeding channels 34 are all fixedly connected to the armature connector 333. By adjusting the adjusting nut, the armature 331 can move along the screw 332, and then the position of the armature 331 can be adjusted to change the distance between the armature 331 and the electromagnet 32, and then the suction force between the armature 331 and the electromagnet 32 ​​can be adjusted.

[0030] Furthermore, the electromagnet 32 ​​includes a shell fixedly connected to the mounting base 31, an iron core is provided in the shell, and a coil is wound around the iron core. Specifically, the iron core is E-shaped, and two grooves are provided on one side of the iron core, and coils are wound inside the two grooves. The coils are coated with an insulating layer so that only the iron core part of the electromagnet 32 ​​is exposed, thereby achieving sealing of the coil, and a junction box is provided outside the shell, so that the electromagnet 32 ​​can work normally in a powder environment, thereby enabling the weighing and feeding device provided in this embodiment to realize the weighing and feeding of powders.

[0031] The electromagnet 32, the armature assembly 33 and the spring sheet 35 cooperate with each other. When the electromagnet 32 ​​and the armature assembly 33 are attracted, the feeding channel 34 is driven to move toward the electromagnet. When the electromagnet 32 ​​and the armature assembly 33 are separated, the elastic force of the spring sheet 35 drives the feeding channel 34 to reset. In this embodiment, the electromagnet 32 ​​is provided with a high-frequency electromagnetic coil, so that the armature assembly 33 performs high-frequency reciprocating motion, and the feeding channel 34 performs high-frequency reciprocating motion, thereby allowing the material in the feeding channel 34 to be transported from the storage bin 36 to the discharge port 37.

[0032] One end of the weighing sensor is flexibly connected to the frame 1, and a buffer assembly is provided between the end of the weighing sensor away from the frame 1 and the mounting seat 31. The buffer assembly includes a limiting cylinder flexibly connected to the mounting seat 31, and a buffer rod is provided in the limiting cylinder.

[0033] In this embodiment, the buffer assembly is flexibly connected to the mounting seat 31 through the connecting assembly 2, and the connecting assembly includes a first connecting assembly 21 and a second connecting assembly 22 fixedly connected to the mounting seat 31. The first connecting assembly 21 includes a connecting frame 211 fixedly connected to the mounting seat 31, and a connecting ring 1 212 is fixedly connected to the top center of the connecting frame 211. A connecting ring 3 is detachably connected to the bottom of the limiting cylinder. The connecting ring 1 212 is flexibly connected to the connecting ring 3. The second connecting assembly 22 includes a connecting plate 221 fixedly connected to the mounting seat 31, and connecting rings 2 222 are respectively provided at both ends of the connecting plate 221. The connecting rings 2 222 are flexibly connected to the connecting ring 3.

[0034] The feeding channel 34 is closed at one end close to the storage bin 36, and the discharge port 37 is connected to the discharge valve 4. When the weighing and feeding mechanism 3 stops feeding, the electric control box controls the discharge valve 4 to close, thereby preventing the powdered material in the feeding channel 34 from falling along the discharge port 37. In this embodiment, the discharge valve 4 is provided to solve the problem that the material may flow due to the powdered material being too fine. When the material in the feeding channel 34 has no fluidity, the weighing and feeding device provided in this embodiment does not need to be provided with the discharge valve 4.

[0035] The feeding channel 34 is located between the discharge port 37 and the storage bin 36 and is provided with a discharge speed adjustment component 38 for controlling the feeding speed of the weighing and feeding mechanism 3 .

[0036] Furthermore, the discharge speed adjustment component 38 includes a mounting shaft 381 rotatably connected to the feeding channel 34, a speed adjustment baffle 382 is fixedly connected to the mounting shaft 381, the speed adjustment baffle 382 is located in the feeding channel, one end of the mounting shaft 381 extending out of the feeding channel is fixedly connected to a baffle handle 383, a dial 384 is sleeved on the mounting shaft 381 between the baffle handle 383 and the feeding channel, the dial 384 is fixedly connected to the feeding channel, a plurality of slots 385 are provided on the dial 384, a locking rod 386 is hinged on one side of the baffle handle 383 close to the dial 384, a locking protrusion 387 is provided on the end of the locking rod 386 close to the dial 384, and the locking protrusion 387 is engaged with the slot 385. Adjust the locking rod 386 so that the locking protrusion 387 and the locking groove 385 are disengaged, and rotate the baffle handle 383 to drive the speed adjustment baffle 382 to rotate to control the gap size between the feeding channel 34 and the speed adjustment baffle 382, ​​thereby controlling the feeding speed of the weighing and feeding mechanism 3.

[0037] The weighing and feeding device provided by the utility model, when in use, sets the single feeding value, feeding times and feeding time interval of the weighing and feeding mechanism 3 according to the needs, starts the equipment, and the weighing and feeding mechanism 3 starts feeding. When the set single feeding value is reached, the weighing sensor triggers a signal to the electric control box, and the electric control box controls the weighing and feeding mechanism 3 to stop working, thus completing the single feeding operation.

[0038] The weighing and feeding device provided by the utility model is connected between the weighing and feeding mechanism 3 and the frame 1 through at least one weighing sensor. When measuring weight, the weighing sensor directly measures the weight of the entire weighing and feeding mechanism 3 and the material therein, with higher measuring accuracy, and can achieve feeding while measuring, thereby improving the working efficiency of the equipment.
