[0026] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0027] Figures 1-7 The components include a vibrating head assembly 100, an electromagnet 110, a housing 120, a magnet cover 121, a machine body cover 122, a bottom shell 123, an armature assembly 200, an upper armature connecting frame 210, an armature 220, a lower armature connecting frame 230, an elastic guide assembly 300, a guide connecting rod 310, a first adjusting nut 320, an adjusting screw 330, a first locking nut 331, a second locking nut 332, a third locking nut 333, a partition platform 334, a spring assembly 340, a spring guide sleeve 341, a spring 342, a spring adjusting bracket 343, a soft seal 400, a connector 500, a vibrating feeder connecting seat 600, and an armature air gap adjusting hexagonal bolt 700, etc.

[0028] like Figures 1-7As shown, this invention is a vibrating feeder used for vibratory feeding. The specific technical solution for vibratory feeding includes a vibrating head assembly 100, which serves as the excitation source for vibration, providing the power required for vibration. An armature assembly 200 cooperates with the vibrating head assembly 100 and is driven by the vibrating head assembly 100 to vibrate. The armature assembly 200 and the vibrating head assembly 100 are connected by an elastic guide assembly 300, which enables the armature assembly 200 to vibrate at a set frequency, achieving the purpose of vibratory feeding. To ensure the reliable and stable operation of the armature assembly 200, two sets of elastic guide assemblies 300 are provided, positioned on both sides of the armature assembly 200. The upper and lower ends of the elastic guide assemblies 300 are fixedly connected to corresponding parts of the vibrating head assembly 100 to achieve reliable vibration of the armature assembly 200.

[0029] Furthermore, in order to achieve reliable vibration feeding, the vibratory head assembly 100 includes a housing 120 and an electromagnet 110 installed in the housing 120. The armature assembly 200 and the elastic guide assembly 300 are both disposed in the housing 120. The two ends of the elastic guide assembly 300 are fixed to the corresponding parts of the vibratory head assembly 100. The armature assembly 200 is connected to the elastic guide assembly 300 and can vibrate at a certain frequency on the elastic guide assembly 300.

[0030] The armature assembly 200 is used to connect to an external vibrating trough to achieve power output and ensure stable vibration feeding of granular and powdery materials during operation.

[0031] Furthermore, such as Figure 5 As shown, to facilitate the installation of the armature assembly 200 and the elastic guide component 300 within the housing 120, the housing 120 includes a magnet cover 121, a body cover 122, and a bottom cover 123. The flanged structure at the upper end of the body cover 122 covers the flange plate at the lower part of the magnet cover 121 and is fastened by cylindrical head screws. The bottom cover 123 is mated and connected to the bottom surface of the body cover 122. The upper end of the elastic guide component 300 is fixedly connected to the magnet cover 121, and the lower end of the elastic guide component 300 is fixedly connected to the bottom cover 123. Both ends of the armature assembly 200 are respectively connected to the corresponding elastic guide components 300, and the armature assembly 200 can vibrate relative to the elastic guide component 300 at a set frequency. In practice, to ensure a reliable alignment and connection between the bottom shell 123 and the body cover 122, an upper step is formed at the upper end of the bottom shell 123, and a lower step is formed at the lower end of the body cover 122. The upper and lower steps cooperate with each other to ensure a reliable and stable connection between the bottom shell 123 and the body cover 122. To ensure the structural stability and reliability of the magnet cover 121, reinforcing ribs are provided between the housing portion of the magnet cover 121 used to house the electromagnet 110 and the flange plate at the lower end.

[0032] It is understood that the armature assembly 200 includes an upper armature connecting frame 210, an armature 220, and a lower armature connecting frame 230. The armature 220 is placed between the upper armature connecting frame 210 and the lower armature connecting frame 230. The upper armature connecting frame 210 and the lower armature connecting frame 230 are connected by an armature air gap adjusting hexagonal bolt. The edges of the mating surfaces of the upper armature connecting frame 210 and the lower armature connecting frame 230 are provided with connecting flange plates. The armature air gap adjusting hexagonal bolt 700 connects the connecting flange plates of the upper armature connecting frame 210 and the lower armature connecting frame 230. Both ends of the lower armature connecting frame 230 are connected to the corresponding elastic guide components 300 to achieve reliable and stable vibration operation of the armature assembly 200.

[0033] In practice, the lower armature connecting frame 230 is fastened to the bottom of the connecting piece 500. The lower part of the connecting piece 500 extends out of the outer side of the housing 120, and the vibratory feeder connecting seat 600 is welded to the lower end of the connecting piece 500. The bottom surface of the bottom housing 123 forms an axially extending cylindrical part. The upper circumferential surface of the vibratory feeder connecting seat 600 is connected to the cylindrical part of the bottom housing 123 by a soft seal 400. It can be understood that in order to achieve a reliable connection with external components, the four corners of the vibratory feeder connecting seat 600 are respectively provided with a connecting part for external connection. In practice, the connecting piece 500 is usually constructed as a cylinder, and the top of the connecting piece 500 is fixedly connected to the lower armature connecting frame 230 by connecting bolts.

[0034] Furthermore, in order to achieve reliable vibration operation of the armature assembly 200 during operation, each set of elastic guide components 300 includes two guide connecting rods 310 arranged in parallel with each other. The upper end of the guide connecting rod 310 is fixedly connected to the magnet cover 121, and the lower end of the guide connecting rod 310 is fixedly connected to the bottom shell 123. A set of spring assemblies 340 are respectively fitted on the upper and lower parts of the two guide connecting rods 310.

[0035] The spring assembly 340 includes a spring guide sleeve 341, a spring 342, and a spring adjusting bracket 343. The two through holes of the spring adjusting bracket 343 are guided and engaged with the corresponding two guide connecting rods 310. The two ends of the spring 342 are respectively pressed onto the spring guide sleeve 341 and the spring adjusting bracket 343. The threaded hole between the two through holes of the spring adjusting bracket 343 is threadedly connected to the adjusting screw 330. In practice, the threaded hole of the spring adjusting bracket 343 is formed by a nut sleeve integrally connected to the spring adjusting bracket 343. Furthermore, the threads on the upper and lower parts of the adjusting screw 330 are respectively arranged in opposite directions. The upper and lower parts of the adjusting screw 330 are integrally connected by a partition platform 334. The two ends of the armature assembly 200 are supported on the partition platform 334 and locked by the first locking nut 331. The adjusting screw 330 is also threaded with a second locking nut 332 and a third locking nut 333. The second locking nut 332 is used to limit the upper spring adjustment bracket, and the third locking nut 333 is used to limit the lower spring adjustment bracket.

[0036] Furthermore, in order to guide the end of the spring 342 near the spring adjusting bracket 343, an integrally connected spring seat is constructed on the spring adjusting bracket 343, and the corresponding end of the spring 342 is fitted into the spring seat. The spring seat is provided with a through hole of the spring adjusting bracket 343 to pass through and install the guide connecting rod 310, so as to achieve a reliable guiding effect on the lifting and lowering movement of the spring adjusting bracket 343.

[0037] During use, when the frequency of the vibrating feeder needs to be adjusted, the distance between the upper and lower spring adjusting brackets 343 can be adjusted by rotating the adjusting screw 330. Since the upper and lower threads of the adjusting screw 330 have opposite directions of rotation (i.e., the adjusting screw 330 is a forward and reverse thread screw), rotating the adjusting screw 330 causes the upper and lower spring adjusting brackets 343 to move closer or further apart. Once the spring adjusting brackets 343 are adjusted relative to the adjusting screw 330, the corresponding second locking nut 332 and third locking nut 333 are rotated. The compression of the spring 342 is adjusted by rotating the adjusting screw 330 to limit the corresponding spring adjusting bracket 343. This adjustment method involves adjusting the compression of the spring 342 between the upper and lower sets of spring assemblies 340. In addition to the above adjustment method, the compression of the spring assembly 340 can also be adjusted by rotating the first adjusting nut 320 on the guide connecting rod 310, that is, by adjusting the compression of the spring assembly 340 from the outside to the inside of the two sets of spring assemblies 340. This allows for convenient and quick adjustment of the vibration frequency of the vibrating feeder of the present invention.
