Example 1
Fig. 1 is a schematic structural view of a magnetic powder supply device according to the present utility model. As shown in fig. 1, the magnetic powder supply device of the present embodiment includes a storage unit 1, a vibration feeding unit 2, a weighing unit 3, a sealing unit 4, a baffle 42, and a magnetic powder output pipe 43. The following is a detailed description.
The sealing unit 4 includes a seal housing 41. In the present embodiment, the seal case 41 may form a rectangular accommodation space. A part of the storage unit 1, the vibratory feeding unit 2 and the weighing unit 3 are located in a sealed housing 41. This can reduce the oxygen content in the magnetic powder and contribute to the improvement of the performance of the magnet. In this embodiment, the top of the seal housing 41 is provided with a storage unit inlet, and the bottom thereof is provided with a magnetic powder outlet.
The storage unit 1 comprises a storage tank 11, a fixing device 12 and a discharge pipeline 13. The storage tank 11 is disposed above the seal case 41. The top of storage tank 11 is provided with charge door 111, and the bottom of storage tank 11 is provided with discharge gate 112. The discharge port 112 corresponds to a storage unit inlet of the seal housing 41. The fixing device 12 is provided at the outer circumference of the storage tank 11 for fixing the storage tank 11. In this embodiment, the securing device 12 is a flange. The discharge pipeline 13 is arranged at the discharge port 112. The discharge line 13 is connected movably to the storage tank 11. The discharge line 13 is arranged in the sealed housing 41.
The vibratory feeding unit 2 includes a feeding tray 21, a vibrator 22, and a base 23. The feeding tray 21 is arranged below the discharge port 112 and is in clearance contact with the discharge pipeline 13. The feed tray 21 receives magnetic powder from the storage unit 1. The vibrator 22 is disposed below the feed tray 21. The vibrator 22 drives the feed tray 21 to vibrate. A base 23 is provided below the vibrator 22 for mounting and fixing the vibratory feeding unit 2. When the vibrator 22 drives the feeding tray 21 to vibrate, the discharging pipeline 13 is correspondingly driven to vibrate, so that the magnetic powder in the discharging pipeline 13 falls into the feeding tray 21. The vibrator 22 is connected to a controller in the weighing unit 3. The vibrator 22 starts vibrating under a movement instruction of the controller or stops vibrating under a stop instruction of the controller.
The weighing unit 3 is positioned at one side of the vibration feeding unit 2. The weighing unit 3 includes a weighing and overturning bucket 31, a mass sensor 32, a position sensor (not shown), a controller (not shown), and a weighing cylinder (not shown). The scale hopper 31 receives magnetic powder from the feed tray 21. The mass sensor 32 is used for sensing the weight of the weighing and overturning bucket 31 and transmitting signals to the controller. The position sensor is used for sensing whether the output end of the weighing cylinder is reset or not and transmitting signals to the controller. The controller receives signals from the mass sensor 32 and the position sensor and issues commands to the vibrator 22 and the scale cylinder, respectively. The vibrator 22 vibrates under the instruction of the controller, so that the magnetic powder in the material outlet pipeline 13 falls into the feeding tray 21, and meanwhile, the magnetic powder in the feeding tray 21 falls into the weighing overturning bucket 31. The weighing cylinder can stretch out and draw back under the motion instruction of the controller, so that the weighing overturning bucket 31 overturns, and magnetic powder can be dumped to a corresponding magnetic powder feeding device.
The baffle 42 is disposed in the sealed housing 41 and above a side of the magnetic powder output port away from the weighing unit 3. The provision of the baffle 42 helps to enable the magnetic powder to fall into the magnetic powder outlet. The magnetic powder output pipeline 43 is arranged outside the sealing shell 41, below the sealing shell 41 and at the magnetic powder output port. One end of the magnetic powder output pipeline 43 is connected with the sealed shell 41, and the other end can supply magnetic powder to a corresponding magnetic powder feeding device so as to feed the magnetic powder into the die.
The following describes the working principle of the magnetic powder supply device of the present embodiment:
when the feeding device is in operation, the feeding disc 21 vibrates along with the vibration of the vibrator 22, and meanwhile, the feeding disc 21 drives the discharging pipeline 13 to vibrate, so that the magnetic powder in the storage unit 1 and the discharging pipeline 13 enters the feeding disc 21. When the feeding tray 21 vibrates, the magnetic powder in the feeding tray 21 continuously falls into the weighing overturning hopper 31.
When the weight of the weighing and overturning bucket 31 reaches a set value, the mass sensor 32 transmits a signal to the controller, and then the controller sends a motion instruction to the weighing cylinder, and the output end of the weighing cylinder performs telescopic motion to enable the weighing and overturning bucket 31 to overturn, so that magnetic powder is dumped to a corresponding magnetic powder feeding device. At the same time, the controller gives a stop instruction to the vibrator 22, and the vibrator 22 stops vibrating. When the output end of the weighing cylinder is in a contracted state (namely reset), after receiving signals from the position sensor, the controller sends a movement instruction to the vibrator 22, the vibrator 22 starts vibrating under the movement instruction of the controller, the feeding disc 21 also starts vibrating, and magnetic powder in the feeding disc 21 continuously falls into the weighing overturning hopper 31, namely the magnetic powder feeding process of the next round is started.
The present utility model is not limited to the above-described embodiments, and any modifications, improvements, substitutions, and the like, which may occur to those skilled in the art, fall within the scope of the present utility model without departing from the spirit of the utility model.
