Description

Technical Field

[0001] This utility model relates to the field of piezoelectric composite loudspeaker production technology, and in particular to a ceramic powder screening device for piezoelectric composite loudspeaker production. Background Technology

[0002] Piezoelectric composite materials are made by combining piezoelectric ceramics and polymer matrices in a certain volume or mass ratio, and with a certain connection method or a certain spatial geometric distribution.

[0003] Piezoelectric composite loudspeakers require the use of ceramic powder for sintering. The ceramic powder used needs to be pre-screened. In existing screening methods, due to the fineness of the powder, it is very easy to cause blockage during the screening process. Therefore, it is necessary to impact the screening device during screening. Existing screening equipment has a small screen area and slow screening speed. Moreover, after the powder flows into the collection hood, there are problems of adhesion and inability to be discharged quickly. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a ceramic powder sieving device for the production of piezoelectric composite loudspeakers.

[0005] This utility model is achieved through the following technical solution: A ceramic powder sieving device for producing piezoelectric composite loudspeakers includes a collecting cover, a drive mechanism fixed to the outside of the collecting cover, a connecting frame fixed to the inner side of the top of the collecting cover, a sieving net fixed to the bottom of the connecting frame, an impact block fixed to the bottom of the sieving net, and an impact mechanism disposed inside the collecting cover. The drive mechanism includes a drive frame, a motor, a reciprocating mechanism, a telescopic rod, and a guide seat. The drive frame is fixedly disposed on the outside of the collecting cover, the motor is fixedly disposed on the top of one end of the drive frame, one end of the reciprocating mechanism is sleeved and fixed to the output end of the motor, the telescopic rod is movably connected to one end of the reciprocating mechanism, and the guide seat is fixedly installed at the bottom of one end of the drive frame. The impact mechanism includes a moving rod, a guide rod, a spring, a collision seat, and a collision ring. The moving rod is engaged inside the collecting cover, the guide rod is fixed to the inside of one end of the collecting cover, the spring is sleeved on the outside of the guide rod, the collision seat is fixedly disposed on the top of the moving rod, and the collision ring is fixedly disposed on the outside of one end of the moving rod.

[0006] In a preferred embodiment of the present invention, one end of the movable rod passes through and extends to the outside of one side of the collection cover, the collision ring is disposed on the outside of one side of the collection cover, and one end of the telescopic rod contacts one end of the movable rod. When the motor controls the reciprocating mechanism to move, thereby controlling the movement of the telescopic rod, the telescopic rod pushes forward to move the moving rod, and causes the collision ring to collide with the outside of the collection hood, causing the collection hood to vibrate and shake off the powder adhering inside.

[0007] In a preferred embodiment of this utility model, the guide seat is provided with a guide hole that cooperates with the telescopic rod; In a preferred embodiment of the present invention, the top of the collision seat is provided with a slot, and the top slot of the collision seat is engaged with the bottom of the impact block; The reciprocating motion of the telescopic rod causes the impact block to collide with the impact seat when it moves left and right, which in turn causes the screen bag to vibrate and the powder inside to fall off quickly.

[0008] In a preferred embodiment of this utility model, a sliding hole is provided at one end of the moving rod, one end of the guide rod is locked in the sliding hole at one end of the moving rod, and one end of the spring is in contact with one end of the moving rod. When the telescopic rod retracts, the moving rod automatically returns to its original position under the action of the spring. During this process, the collision seat generates a secondary collision with the impact block.

[0009] In a preferred embodiment of this utility model, a guide groove is provided inside the sliding hole at one end of the moving rod, and a guide strip that cooperates with it is provided on the surface of the guide rod, so that the moving rod can move horizontally.

[0010] The beneficial effects of this utility model are: The ceramic powder screening device for piezoelectric composite loudspeaker production is equipped with a multi-compartment, W-shaped screening mesh bag, which greatly increases the mesh area. Under the action of the motor and reciprocating mechanism, the collision seat collides with the impact block at the bottom of the screening mesh bag, and the collision ring impacts the collection cover, thereby enabling the powder in the screening mesh bag to be screened quickly and preventing the powder from accumulating inside the collection cover.

[0014] like Figure 1-3 The ceramic powder sieving device for producing piezoelectric composite loudspeakers shown includes a collecting cover 1, a drive mechanism 2 fixed to the outside of the collecting cover 1, a connecting frame 3 fixed to the inner side of the top of the collecting cover 1, a sieving net 4 fixed to the bottom of the connecting frame 3, an impact block 5 fixed to the bottom of the sieving net 4, and an impact mechanism 6 disposed inside the collecting cover 1. The drive mechanism 2 includes a drive frame 21, a motor 22, a reciprocating mechanism 23, a telescopic rod 24, and a guide seat 25. The drive frame 21 is fixedly disposed on the outside of the collecting cover 1, and the motor 22 is fixedly disposed on one end of the drive frame 21. At the top, one end of the reciprocating mechanism 23 is sleeved and fixed to the output end of the motor 22. The telescopic rod 24 is movably connected to one end of the reciprocating mechanism 23. The guide seat 25 is fixedly installed at the bottom of one end of the drive frame 21. The impact mechanism 6 includes a moving rod 61, a guide rod 62, a spring 63, an impact seat 64, and an impact ring 65. The moving rod 61 is locked inside the collection cover 1. The guide rod 62 is fixed inside one end of the collection cover 1. The spring 63 is sleeved outside the guide rod 62. The impact seat 64 is fixedly installed on the top of the moving rod 61. The impact ring 65 is fixedly installed on the outside of one end of the moving rod 61.

[0015] Specifically, one end of the moving rod 61 passes through and extends to the outside of one side of the collecting cover 1, the collision ring 65 is set on the outside of one side of the collecting cover 1, one end of the telescopic rod 24 contacts one end of the moving rod 61, the guide seat 25 has a guide hole that cooperates with the telescopic rod 24, the top of the collision seat 64 has a slot, the top slot of the collision seat 64 is locked at the bottom of the impact block 5, one end of the moving rod 61 has a sliding hole, one end of the guide rod 62 is locked in the sliding hole at one end of the moving rod 61, one end of the spring 63 contacts one end of the moving rod 61, the sliding hole at one end of the moving rod 61 has a guide groove, the surface of the guide rod 62 has a guide strip that cooperates with it, and the moving rod 61 moves horizontally.

[0016] In this embodiment, multiple screening nets 4 with trapezoidal vertical cross sections are fixed side by side and fixed to the top of the inner side of the collection cover 1 by the connecting frame 3, so that they are arranged in a W shape. After the ceramic powder to be screened is poured into the screening net 4, the motor 22 is started. At this time, the motor 22 drives the reciprocating mechanism 23 fixed to it to rotate. The reciprocating mechanism 23 drives the telescopic rod 24 connected to it at the other end to reciprocate under the guidance of the guide seat 25, thereby applying pressure to the moving rod 61.

[0017] Furthermore, when the telescopic rod 24 moves forward, the moving rod 61 is pressed, causing the inner end of the collision seat 64 fixed on its surface to collide with the bottom impact block 5 of the screen bag 4. When the telescopic rod 24 moves backward, under the action of the spring 63 and guided by the guide rod 62, it extends outward to the outside of the collection cover 1. At this time, the inner side of the collision seat 64 collidees with the impact block 5 a second time. Under frequent impacts, the screen bag 4 shakes and causes the powder inside to collide with the screen bag 4, causing the powder to fall off quickly and avoiding caking and clogging of the screen holes. When the moving rod 61 pushes forward, the collision ring 65 will also collide with the outside of the collection cover 1, causing the collection cover 1 to vibrate, thereby preventing the powder inside from accumulating and adhering, and ensuring the discharge effect. A guide strip is provided on the surface of the guide rod 62, and a guide groove is opened in the sliding hole at one end of the moving rod 61 to cooperate with it, ensuring that the moving rod 61 will not rotate when it moves horizontally. Multiple collision seats 64 collide with the bottom impact block 5 of the screen bag 4 simultaneously to ensure the screening effect.
