Since the running track is set in an arc shape, the arc-shaped running track can expand the moving range of the trough, thereby increasing the amplitude of the trough vibration, so that the feeder can be used in large-amplitude conveying scenarios.

[0016] (2) When the material trough vibrates under the drive of the electromagnetic drive module, the material trough will transmit part of the vibration to the base through the first elastic component, so the base will generate a small vibration. At this time, the vibration of the base will be transmitted to the counterweight plate through the second elastic component, thereby driving the counterweight plate to vibrate. The vibration direction of the counterweight plate is opposite to the vibration direction of the material trough. Therefore, the vibration of the counterweight plate installed on the base will offset the vibration transmitted to the base by the material trough, thereby greatly improving the stability of the base and reducing the vibration of the base.

[0017] (3) When the material trough vibrates laterally, the material trough will drive the second fixed rod to move laterally. The inclined connecting rod can change the direction of movement. The second fixed rod drives the sliding plate to move longitudinally along the slide rail through the connecting rod. The sliding plate drives the material moving rod to move.

DETAILED DESCRIPTION

[0026] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0027] The following is combined with Figure 1 To Attachment Figure 6 The present invention is described in detail with reference to specific embodiments.

[0028] Example 1

[0029] Reference Figure 1-3 An electromagnetic vibrating feeder provided by the present invention includes a base 1 and a material trough 2 located above the base 1, and a plurality of first elastic components 3 are arranged between the base 1 and the material trough 2. In this embodiment, the first elastic components 3 are specifically arranged as four, and the first elastic components 3 include an upper fixed block 30 and a lower fixed block 31. The upper fixed block 30 is fixedly installed at the bottom of the material trough 2, and the lower fixed block 31 is fixedly installed at the top of the base 1. Two leaf springs 32 are fixedly installed between the upper fixed block 30 and the lower fixed block 31. Due to the elastic properties of the leaf springs 32 themselves, the material trough 2 can move laterally on the base 1.

[0030] An electromagnetic driving module 4 for driving the material trough 2 to vibrate is arranged on the base 1, and the electromagnetic driving module 4 includes an arc-shaped running track 40, and the running track 40 is fixedly installed on the base 1, and an electromagnetic coil 41 is fixedly installed at the bottom of the material trough 2, and the electromagnetic coil 41 is slidably arranged in the running track 40, and multiple permanent magnet blocks 42 are fixedly connected to the inner walls on both sides of the running track 40, and the multiple permanent magnet blocks 42 are arranged along the length direction of the running track 40. The electromagnetic coil 41 is connected to an AC power supply with a controller. When the electromagnetic coil 41 is energized, a magnetic field will be generated. The permanent magnet block 42 itself has a magnetic field. Therefore, according to the principle that like repels like and opposites attract, a repulsive force or an attractive force will be generated between the electromagnetic coil 41 and the permanent magnet block 42, that is, a driving force is generated. The current direction of the AC power supply changes periodically, so the direction of the magnetic field generated by the electromagnetic coil 41 will also change periodically. Therefore, the electromagnetic coil 41 will reciprocate in the running track 40, thereby driving the material trough 2 to vibrate; at the same time, the AC power supply usually has a controller to adjust the current size and period of the AC power, so that the vibration frequency of the material trough 2 can be adjusted by the controller.

[0031] In this embodiment, the electromagnetic drive module 4 is set as a group. In other embodiments, the electromagnetic drive module 4 can be set as multiple groups and arranged in an array between the base 1 and the material trough 2. Increasing the number of electromagnetic drive modules 4 will increase the driving force accordingly, thereby further increasing the amplitude.

[0032] A counterweight mechanism 5 is also provided on the base 1, and the counterweight mechanism 5 includes a mounting plate 50, which is mounted on the base 1 through a second elastic component 51. The second elastic component 51 has the same structure as the first elastic component 3, so it is not described here; a plurality of counterweight plates 52 are detachably mounted on the mounting plate 50, and two mounting bolts 53 are vertically fixedly connected to the mounting plate 50, and the mounting bolts 53 simultaneously penetrate the plurality of counterweight plates 52 upward, and a mounting nut 54 is threadedly connected to the top of the mounting bolt 53, and the mounting nut 54 presses the counterweight plate 52, so that the counterweight plate 52 can be detachably mounted on the mounting plate 50.

[0033] When the material trough 2 vibrates under the drive of the electromagnetic drive module 4, the material trough 2 will transmit part of the vibration to the base 1 through the first elastic component 3, so the base 1 will generate a small vibration. At this time, the vibration of the base 1 will be transmitted to the counterweight plate 52 through the second elastic component 51, thereby driving the counterweight plate 52 to vibrate, and the vibration direction of the counterweight plate 52 is opposite to the vibration direction of the material trough 2. Therefore, the vibration of the counterweight plate 52 installed on the base 1 will offset the vibration transmitted to the base 1 by the material trough 2, thereby greatly improving the stability of the base 1 and reducing the vibration of the base 1; and the counterweight plate 52 can be detachably installed on the mounting plate 50, so the number of counterweight plates 52 can be adjusted according to the actual vibration conditions.

[0034] A support frame 6 is also provided below the base 1. The support frame 6 includes four support legs 60. A reinforcing cross beam 61 is fixedly connected between two adjacent support legs 60 to improve the stability of the support legs 60. A shock absorber 62 is fixedly installed on the top of the support leg 60. In this embodiment, the shock absorber 62 is a shock-absorbing rubber block 620. In other embodiments, the shock absorber 62 may also be other components with shock-absorbing effect such as a shock-absorbing spring. The shock absorber 62 can further absorb the vibration of the base 1 and improve the stability of the base 1.

[0035] An inclination adjustment assembly 63 is provided between the shock absorbing member 62 and the base 1. The inclination adjustment assembly 63 includes a fixed plate 630 and an adjustment plate 631. The fixed plate 630 and the adjustment plate 631 are both fixedly mounted on the shock absorbing member 62. One end of the base 1 is rotatably connected to the fixed plate 630, and the other end of the base 1 is movably arranged on the adjustment plate 631. An adjustment slot 6310 is vertically provided on the adjustment plate 631. Adjustment bolts 632 are threadedly connected to both sides of the base 1. The adjustment bolts 632 are movably arranged in the adjustment slots 6310. When the inclination of the base 1 is adjusted to the right position, the adjustment bolts 632 are tightened so that the adjustment bolts 632 press the adjustment plate 631 to fix the base 1. The actual purpose of adjusting the inclination of the base 1 is to adjust the inclination of the trough 2, so that the open end of the trough 2 is tilted downward, so that the material is subjected to the component force of its own gravity, thereby accelerating the conveying speed of the material.

[0036] The implementation principle of an electromagnetic vibrating feeder in Example 1 is as follows: when alternating current is passed through the electromagnetic coil 41, a magnetic field is generated, and the direction of the magnetic field changes periodically. According to the principle that like charges repel each other and opposite charges attract each other, a driving force is generated between the electromagnetic coil 41 and the permanent magnet block 42, and the electromagnetic coil 41 is made to reciprocate in the running track 40, and the electromagnetic coil 41 drives the material trough 2 to vibrate. Since the running track 40 is arranged in an arc shape, the arc-shaped running track can expand the moving range of the material trough 2, thereby increasing the amplitude of the vibration of the material trough 2, so that the feeder can be used in large-amplitude conveying scenarios.

[0037] Example 2

[0038] Reference Figure 4 The difference between this embodiment and the first embodiment is that the running track 40 is fixedly installed at the bottom of the trough 2, two clamping plates 43 are fixedly connected to the base 1, and the electromagnetic coil 41 is fixedly installed between the two clamping plates 43, that is, the electromagnetic coil 41 is fixedly installed on the base 1 through the clamping plates 43. When the electromagnetic coil 41 is supplied with alternating current, a magnetic field is generated, and the direction of the magnetic field changes periodically. According to the principle that like charges repel and opposite charges attract, a driving force is generated between the electromagnetic coil 41 and the permanent magnet block 42, thereby driving the running track 40 to reciprocate, and the running track 40 drives the trough 2 to vibrate.

[0039] Example 3

[0040] Reference Figure 5 and Figure 6 The difference between this embodiment and embodiment 1 is that a material shifting mechanism 7 is further provided on the base 1, and the material shifting mechanism 7 includes two extended fixed blocks 70, and the extended fixed blocks 70 are fixedly connected to both sides of the base 1, and two support rods 71 ​​are vertically fixedly connected to the extended fixed blocks 70, and a top plate 72 is fixedly connected to the top of the support rods 71, and the top plate 72 is located above the material trough 2, and two slide rails 73 are longitudinally fixedly connected to the bottom surface of the top plate 72, and a sliding plate 74 is longitudinally slidably connected to the slide rails 73, and a plurality of material shifting rods 75 are vertically fixedly connected to the bottom surface of the sliding plate 74, and the material shifting rods 75 extend downward into the material trough 2.

[0041] A connecting assembly 76 for driving the sliding plate 74 to move is provided between the sliding plate 74 and the material trough 2, and the connecting assembly 76 includes a first fixed rod 760 and a second fixed rod 761. The first fixed rod 760 is fixedly connected to the middle position of the side of the sliding plate 74, and the second fixed rod 761 is vertically fixedly connected to the side wall of the material trough 2. A connecting rod 762 is obliquely arranged between the first fixed rod 760 and the second fixed rod 761, and one end of the connecting rod 762 is hinged to the first fixed rod 760 through a ball hinge 763, and the other end of the connecting rod 762 is also hinged to the second fixed rod 761 through the ball hinge 763.

[0042] The implementation principle of an electromagnetic vibrating feeder in Example 2 is as follows: when the material trough 2 vibrates laterally, the material trough 2 will drive the second fixed rod 761 to move laterally, and the inclined connecting rod 762 can change the direction of movement. The second fixed rod 761 drives the sliding plate 74 to move longitudinally along the slide rail 73 through the connecting rod 762, and the sliding plate 74 drives the material moving rod 75 to move. The material moving rod 75 can move the material in the material trough 2 to make the material transportation more uniform.
