Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular, to a motor-driven magnetic vibration feeding device. Background Technology

[0002] Currently, the most commonly used equipment for conveying bulk materials is the electromagnetic vibrating feeder, which typically consists of an electromagnetic vibrator, a hopper, and a control system. The continuous conveying of materials is achieved through the vibration generated by the electromagnetic vibrator, and it is widely used in industries such as coal, metallurgy, and chemicals.

[0003] In practical use, when the electromagnetic vibrator is powered on, the electromagnets on it generate magnetic force to attract the armature, thereby driving the hopper to vibrate and causing the material in the hopper to undergo a throwing motion. When the electromagnetic vibrator is powered off, the magnetic field generated by the electromagnets disappears, and the armature returns to its original position under the action of the spring plate. At this time, due to the inertia of the material, the material will continue to move forward. The above process repeats continuously, thus enabling continuous material conveying. For example, the feeders disclosed in Chinese patent documents CN207275576U (Patent Title: A Mineral Processing Electromagnetic Vibrating Feeder) and CN220055186U (Patent Title: An Electromagnetic Vibrating Energy Recovery Feeder) both operate on the principle of electromagnets attracting the armature.

[0004] However, in current electromagnetic vibratory feeders similar to those in the aforementioned patent documents, the electromagnetic vibrator (including electromagnet and armature) is usually located below the hopper. This undoubtedly increases the overall height of the machine, limiting its application scenarios. In addition, the structure is relatively complex and inconvenient to install. Utility Model Content

The driving device includes a motor mounted on the base, a turntable connected to the output shaft of the motor, and an active magnetic sheet mounted on the turntable. A passive magnetic sheet is mounted on the side of the feeding disc near the turntable corresponding to the active magnetic sheet.

[0024] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] Please see Figures 1-5 This utility model provides a motor-driven magnetic vibration feeding device, including a base 1, a drive device 2, a feeding disc 3, and an elastic element 4. The feeding disc 3 is mounted on the base 1 via the elastic element 4. The drive device 2 is mounted on the base 1 and is located on one side of the feeding disc 3 along its length. During operation, the feeding disc 3 vibrates back and forth under the drive of the drive device 2, thereby causing the material on the feeding disc 3 to move forward continuously. Furthermore, the end of the feeding disc 3 closest to the drive device 2 is the feed end, and the end of the feeding disc 3 furthest from the drive device 2 is the discharge end.

[0026] The base 1 is roughly L-shaped and includes a base 11 and a connecting plate 12. Both the base 11 and the connecting plate 12 are flat. The base 11 is horizontally set on a supporting plane (such as a factory floor), and the connecting plate 12 is vertically set and fixedly connected to one side of the base 11. The feed plate 3 is connected to the base 11 via an elastic element 4, and the drive device 2 is mounted on the connecting plate 12.

[0027] In this embodiment, shock-absorbing feet 13 are installed at the four corners of the bottom of the base 11. The shock-absorbing feet 13 are made of shock-absorbing materials such as silicone or rubber to reduce the excessive transmission of vibration from the feed plate 3 to the machine base 1 to the support plane.

[0028] The feed pan 3 has a long groove-shaped structure, with mounting ears 31 protruding outwards from its side. A mounting seat 14 is provided on the upper surface of the base 11. The feed pan 3 is located above the connecting plate 12. The upper end of the elastic element 4 is fixedly connected to the mounting ears 31, and the lower end of the elastic element 4 is fixedly connected to the mounting seat 14. In this embodiment, there are four elastic elements 4. Two elastic elements 4 are provided on each of the opposite sides of the feed pan 3 along its width direction. The four elastic elements 4 can support the feed pan 3, allowing it to be suspended above the connecting plate 12. Correspondingly, there are four mounting ears 31 and four mounting seats 14.

[0029] The elastic element 4 is made of a material that is both rigid and elastic, so that the elastic element 4 can support the feed plate 3. At the same time, when the feed plate 3 is subjected to external force, the feed plate 3 can overcome the elastic force of the elastic element 4 and move.

[0030] Please see Figure 2 In a preferred embodiment, the elastic element 4 is a spring sheet, which can be a stainless steel spring sheet or a copper spring sheet. In the initial state, the elastic element 4 is in an inclined state, and the angle between the elastic element 4 and the longitudinal plane is α, where 10°≤α≤30°. In this embodiment, the angle α between the elastic element 4 and the longitudinal plane is 30°.

[0031] The drive device 2 includes a motor 21, a turntable 22, and an active magnetic plate 23. The motor 21 is fixedly mounted on the connecting plate 12, the turntable 22 is fixedly connected to the output shaft of the motor 21, and the active magnetic plate 23 is fixedly connected to the turntable 22. In this embodiment, the motor 21 and the feed plate 3 are located on opposite sides of the connecting plate 12. The motor 21 is fixedly connected to the surface of the connecting plate 12 away from the feed plate 3. A through slot 121 is provided on the connecting plate 12, and the turntable 22 passes through the through slot 121. The active magnetic plate 23 is fixedly connected to the surface of the turntable 22 away from the motor 21. In addition, a passive magnetic sheet 32 ​​is fixedly installed on the side of the feed tray 3 near the turntable 22. The active magnetic sheet 23 and the passive magnetic sheet 32 ​​correspond to each other. The turntable 22 rotates under the drive of the motor 21, which causes the active magnetic sheet 23 and the passive magnetic sheet 32 ​​to be aligned or misaligned. When the active magnetic sheet 23 and the passive magnetic sheet 32 ​​are aligned, they attract or repel each other magnetically. When they are aligned and attract or repel each other, they can drive the feed tray 3 to move. When they are misaligned, the feed tray 3 will be reset under the action of the elastic element 4, thereby realizing the continuous forward and backward conveying of materials.

[0032] In a preferred embodiment, there are four active magnetic sheets 23, evenly arranged circumferentially on the turntable 22. The magnetic poles of adjacent active magnetic sheets 23 are arranged in opposite directions. For example, if the end of one active magnetic sheet 23 facing the feed plate 3 is the N pole, then the end of the adjacent active magnetic sheet 23 facing the feed plate 3 is the S pole. There are two passive magnetic sheets 32, and their magnetic poles are arranged in the same direction. Thus, when the motor 21 drives the turntable 22 to rotate, the four active magnetic sheets 23 periodically approach or move away from the passive magnetic sheets 32 of the feed plate 3, alternating between attraction and repulsion, thereby causing the feed plate 3 to vibrate in the front-to-back direction.

[0033] In other embodiments, the number of active magnetic plates 23 is 2-6, and the number of passive magnetic plates 32 is 2-4, which is not limited here. Both the active magnetic plates 23 and the passive magnetic plates 32 are magnets. In addition, the polarity of the active magnetic plates 23 and the passive magnetic plates 32 is adjustable. In specific implementations, the N / S pole configuration can be achieved by flipping or replacing the magnetic plates to realize a combination of various vibration modes.

[0034] In this embodiment, the turntable 22 is made of paramagnetic materials such as aluminum. Aluminum is lightweight and strong, which can greatly reduce the overall weight and improve the structural stability under the same load conditions.

[0035] This utility model discloses a motor-driven magnetic vibration feeding device. The driving device 2 is arranged along the length of the feeding disc 3 on one side of the feeding disc 3. Compared with the prior art, this significantly reduces the overall height of the machine, making it suitable for installation in low-ceilinged spaces and facilitating installation. Furthermore, the motor 21 and the feeding disc 22 are located on opposite sides of the connecting plate 12, respectively, without contact, providing good isolation. Cleaning the motor 21 does not require power interruption. The motor 21's speed can be adjusted between 0-3000 r / min, enabling precise adjustment of the feeding amount. The precise linear speed regulation of the motor 21 improves feeding accuracy and expands the feeding flow range.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
