Description

Technical Field

[0001] The utility model relates to a feeder, in particular to an activated feeder based on magnetic drive. Background Art

[0002] An activated feeder is a machine applicable to external conveyance in various open-air storage yards.

[0003] The existing activated feeder includes a frame, a feeding box, excitation springs, vibration isolation springs and a vibration motor. The bottom of the feeding box is connected to the frame through a plurality of vibration isolation springs. A plurality of excitation springs are installed at the side end of the feeding box. The excitation springs are connected to the feeder motor. The vibration motor is of a double-output shaft type. A force wheel is installed on each side shaft. When the vibration motor rotates, the force wheel spring is compressed by air pressure to change the eccentric position of the piston to obtain different excitation forces, so as to realize the change of the feeding amount.

[0004] However, the existing activated feeder has the following disadvantages or deficiencies: the output of the vibration motor is insufficient and cannot be adjusted, and the vibration motor drives a large amount of ineffective output actions in the vertical direction theoretically, resulting in useless work. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an activated feeder based on magnetic drive to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An activated feeder based on magnetic drive includes a frame and a feeding box. A bracket is installed on the feeding box. The bottom of the bracket is connected to the frame through a plurality of vibration isolation springs. One side of the bracket is connected to the side end of the frame through a plurality of excitation springs;

[0008] One end of the bracket away from the excitation spring is installed with an iron core. An electromagnet is arranged at the side end of the iron core. The electromagnet is periodically powered on and off to drive the iron core to intermittently move towards the electromagnet.

[0009] The activated feeder based on magnetic drive as described above: a frame-shaped groove is formed on the frame, and the feeding box is placed in the frame-shaped groove.

[0010] The activated feeder based on magnetic drive as described above: the feeding box includes a box body penetrating up and down and a feeding curve groove plate fixed in the box body and symmetrically arranged;

[0011] The activated feeder based on magnetic drive as described above: further includes an activation block, and the activation block is fixed in the box body.

[0012] The magnetic force-driven activation feeder as described above: The activation block is arranged in an inverted "V" shape.

[0013] The magnetic force-driven activation feeder as described above: The electromagnet is connected to an electronic control unit, and the electronic control unit includes:

[0014] A power supply, an inverter, a rectifier, and a filter connected in sequence.

[0015] The magnetic force-driven activation feeder as described above: The bracket includes a first connecting frame and a second connecting frame that are separately arranged, and the first connecting frame and the second connecting frame are installed on both sides of the box body;

[0016] The first connecting frame is connected to the excitation spring;

[0017] The iron core is embedded in the second connecting frame.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: After the electromagnet is energized, it generates an attractive force on the iron core, which will drive the bracket and the feeding box as a whole to move towards the electromagnet, while stretching the excitation spring, and the vibration isolation spring also deflects to a certain extent. When the electromagnet is powered off, the attractive force on the iron core is lost, and the bracket and the feeding box are reset under the action of the excitation spring and the vibration isolation spring. Thus, during the periodic power-on and power-off process of the electromagnet, the shaking of the feeding box is realized, thereby improving the discharging effect. Using the magnetic field generated by the energized electromagnet to replace the existing vibration motor and its attached pneumatic system, on the one hand, it is convenient to control the magnitude and frequency of the current to adjust the material flow, and on the other hand, it can reduce the problem of the useless work in the vertical direction caused by the existing vibration motor; Description of the Drawings

[0024] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. Like reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0025] As used herein, the term "exemplary" means "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as superior or better than other embodiments.

[0026] In addition, for a better description of the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can be implemented without some specific details. In some instances, methods, means, and elements well known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0027] The present utility model aims to provide a feeder, which utilizes an electromagnet to periodically energize and de-energize to generate a magnetic field to drive a vibration activation feeding system that produces a horizontal reciprocating motion. The specific implementation is as follows:

[0028] Please refer to Figures 1-4 , in an embodiment of the present utility model, an activation feeder based on magnetic drive includes a frame 1 and a feeding box 2. A bracket 7 is installed on the feeding box 2. The bottom of the bracket 7 is connected to the frame 1 through a plurality of vibration isolation springs 4. One side of the bracket 7 is connected to the side end of the frame 1 through a plurality of excitation springs 3. An iron core 6 is installed at one end of the bracket 7 away from the excitation springs 3. An electromagnet 5 is arranged at the side end of the iron core 6. The electromagnet 5 is periodically energized and de-energized to drive the iron core 6 to intermittently move towards the electromagnet 5.

[0029] In this embodiment, when the electromagnet 5 is energized, it generates an attractive force on the iron core 6, thereby driving the entire bracket 7 and the feeding box 2 to move towards the electromagnet 5. At the same time, the excitation springs 3 are stretched, and the vibration isolation springs 4 also deflect to a certain extent. When the electromagnet 5 is de-energized, the attractive force on the iron core 6 is lost, and the bracket 7 and the feeding box 2 are reset under the action of the excitation springs 3 and the vibration isolation springs 4. Thus, during the periodic energization and de-energization of the electromagnet 5, the shaking of the feeding box 2 is realized, thereby improving the discharging effect. By using the electromagnet 5 to generate a magnetic field when energized, instead of the existing vibration motor and its attached pneumatic system, on the one hand, it is convenient to control the magnitude and frequency of the current to adjust the material flow rate, and on the other hand, it can reduce the problem of the existing vibration motor doing useless work in the vertical direction.

[0030] Among them, the electromagnet 5 is connected to an electronic control unit, and the electronic control unit includes a power supply, an inverter, a rectifier, and a filter that are connected in sequence. After the power supply outputs to the rectifier through the inverter and then to the filter, a periodic direct current with adjustable frequency and current magnitude is formed. The current is input into the electromagnet 5 of the device to generate a magnetic field with controllable magnitude, period, and frequency. When the current magnitude reaches the peak segment, the magnetic field of the electromagnet 5 attracts the iron core 6 to drive the box body 201 to approach the electromagnet 5 in the horizontal direction; when the current magnitude drops from the peak segment, under the pulling force of the excitation spring 3, the box body 201 is pulled back in the horizontal direction. Thus, reciprocatingly, the box body 201 forms a periodic vibration action, driving the materials in the activation machine to flow to the outlet under the action of the activation block 203.

[0031] Further, a frame-shaped groove is formed on the frame 1, and the feed box 2 is placed in the frame-shaped groove, so as to maintain the stability around the feed box 2 while realizing the support of the feed box 2.

[0032] Further, the feed box 2 includes a box body 201 that penetrates up and down and a downward feeding curve groove plate 202 that is fixed in the box body 201 and symmetrically arranged; it further includes an activation block 203, and the activation block 203 is fixed in the box body 201. Preferably, the activation block 203 is arranged in an inverted "V" shape.

[0033] Among them, please refer to Figure 4 , a gap is formed between the two ends of the activation block 203 and the downward feeding curve groove plate 202. When the box body 201 moves reciprocally, the activation block 203 follows the reciprocal movement, thereby playing a certain role in separating and guiding the materials. The materials fall along the gap between the activation block 203 and the downward feeding curve groove plate 202, preventing the problem of material blockage.

[0034] Exemplarily, in one implementation manner, the bracket 7 includes a first connecting frame and a second connecting frame that are separately arranged, and the first connecting frame and the second connecting frame are installed on both sides of the box body 201; the first connecting frame is connected to the excitation spring 3; the iron core 6 is embedded in the second connecting frame.

[0035] It should also be supplemented that a floor support frame is installed at the bottom of the frame 1, and the floor support frame is used to raise the frame 1 by a certain height to facilitate the feeding unit to receive the materials falling from the box body 201.

[0036] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.

[0037] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
