[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example 1

[0029] Reference Figure 1-4 , which is the first embodiment of the utility model, discloses an electromagnetic vibrating feeder structure, including a base 1 and a feeding hopper 12 arranged above the base 1, an electromagnetic vibrating assembly 11 is arranged between the top of the base 1 and the bottom of the feeding hopper 12, and the electromagnetic vibrating assembly 11 mainly includes an armature and a magnet coil, wherein the magnet coil is installed on the base 1, and the armature is installed at the bottom of the feeding hopper 12. When the magnet coil is connected to the current, a pulse electromagnetic force is generated between the iron core and the armature to attract each other, causing the main vibration plate spring 13 to deform and store potential energy. When the current is disconnected and the electromagnetic force disappears, the main vibration plate spring The spring 13 releases energy, causing the armature and the iron core to move in opposite directions, thereby driving the feeding hopper 12 to perform high-frequency reciprocating vibration. Under the action of the vibration, the material in the feeding hopper 12 is thrown at a certain angle and moves in a certain direction to achieve quantitative feeding. The lifting and sliding of the material box 3 is set obliquely above the feeding hopper 12, and the discharge channel 4 is set at the bottom of the material box 3 and is synchronously lifted and lowered with the material box 3. One end of the discharge channel 4 is connected to the inner cavity of the material box 3, and the other end extends into the feeding hopper 12, and the angle of the discharge channel 4 is adjustable to ensure that the material discharged from the discharge channel 4 falls into the feeding hopper 12 to avoid leakage and waste.

[0030] Example 2

[0031] Reference Figure 1-4, which is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that: two symmetrically distributed main vibration plate springs 13 are installed between the top of the base 1 and the bottom of the feeding hopper 12, which are one of the components of the electromagnetic vibration feeder and use elastic potential energy to participate in the repeated vibration operation of the feeding hopper 12. One end of the base 1 is fixedly installed with a base 2, and the top of the base 2 is vertically fixedly installed with a lifting cylinder 21. The output end of the lifting cylinder 21 is connected to a U-shaped bracket 22. The top ends of the U-shaped bracket 22 are respectively fixedly installed on the two outer walls of the material box 3. The lower bottom of the material box 3 is connected to a discharge trough 31. The discharge trough 3 Two fixing seats 32 are vertically fixedly installed on the bottom. A rotation hole 33 is opened on the opposite side of the two fixing seats 32. Screws 34 are threadedly installed on the two opposite outer walls of the two fixing seats 32. A square rubber frame 41 is connected between the top of the feeding channel 4 and the bottom of the discharge trough 31. The elastic deformation property of the square rubber frame 41 is utilized to ensure that the top of the feeding channel 4 is always connected to the inner cavity of the discharge trough 31 after the angle is adjusted. Rotation shafts 42 are vertically fixedly installed on the two opposite outer walls of the feeding channel 4. The two rotation shafts 42 are respectively rotatably installed in the corresponding rotation holes 33 and respectively interfere with the corresponding screws 34.

[0032] The remaining structures are the same as those of Example 1.

[0033] The workflow of this utility model is as follows:

[0034] The first step is to adjust the height of the material box 3 according to the material drop height at the output end of the production equipment, reduce the distance between the material box 3 and the output end of the production equipment, so as to prevent the material discharged from the output end of the production equipment from spilling out of the material box 3. The specific adjustment step is to start the lifting cylinder 21 and push the height of the material box 3 through the U-shaped bracket 22. As the height of the material box 3 increases, the discharge chute 31, the two fixed seats 32 and the discharge channel 4 rise synchronously. At this time, the lower output port of the discharge channel 4 is not relative to the feeding hopper 12, that is, the material sliding from the discharge channel 4 cannot fall smoothly into the feeding hopper 12;

[0035] In the second step, the two screws 34 are loosened again so that the screws 34 no longer interfere with the corresponding rotating shafts 42, and the two rotating shafts 42 can rotate in the corresponding rotating holes 33, so that the rotation angle of the discharge channel 4 can be adjusted until the inclination angle of the lower output port of the discharge channel 4 is relative to the position of the feeding hopper 12. Finally, the two screws 34 are tightened to squeeze and interfere with the corresponding rotating shafts 42, so that the discharge channel 4 and the two fixing seats 32 remain relatively fixed. During the process of adjusting the angle of the discharge channel 4, the square rubber frame 41 will be deformed synchronously, but it is always ensured that the discharge channel 4 is connected to the discharge chute 31 and the inner cavity of the material box 3;

[0036] The third step is to start the electromagnetic vibration component 11 to drive the feeding hopper 12 to perform high-frequency reciprocating vibration, thereby starting feeding.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
