【Background technique】

In the magnetic material industry, the semi-finished green body needs to be powdered after being processed by a cutting machine, that is, it is fully mixed with raw powder to remove the dust on its surface. At present, the powder-feeding of green semi-finished products is carried out manually by using ordinary screens. During the powder-feeding process, there is a lot of dust in the workshop. In addition, the manual operation is not only low in work efficiency and heavy in labor, but also easily causes gaps or breakage in the product. damage.

【Content of invention】

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a high-efficiency powder powder machine for semi-finished green bodies with reasonable structure and novel design, which can replace manual powder processing.

In order to solve the problems of the technologies described above, the utility model adopts the following technical solutions:

The high-efficiency powder passing machine for green semi-finished products includes a vibrator, a base for fixing the vibrator, and a rotating sieve tray arranged on the upper end of the base to accept the semi-finished green body. Above the spiral groove and accept the screening groove at the end of the spiral groove, the spiral groove is provided with the raw powder which is mixed and rubbed with the semi-finished green body and removes the dust on the surface, and the raw powder is provided on the screening groove for the raw powder to fall into The screening hole of the lower spiral groove, the end of the screening groove is provided with a discharge groove, and the vibrator drives the rotating sieve plate to vibrate and drives the semi-finished green body to rotate upwards and output through the discharge groove.

Preferably, it also includes a controller connected with the vibrator and controlling the vibration frequency of the vibrator.

Preferably, the spiral groove has two layers.

Preferably, the spiral groove and the screening groove are integrally formed, and the spiral groove and the screening groove may be interlaced in a circumferential direction, or butted in a circular direction.

Preferably, the shape of the screening holes is circular or oval.

Compared with the prior art, the utility model has the beneficial effects of improving work efficiency, reducing the labor load of workers, maintaining the workshop environment, and reducing the defective rate of products at the same time.

【Description of drawings】

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the top view of the utility model embodiment;

Fig. 3 is a side view of the utility model embodiment.

【Detailed ways】

As shown in Figure 1, Figure 2, and Figure 3, a high-efficiency powder passing machine for green semi-finished products includes a vibrator, a base 1 for fixing the vibrator, and a rotating sieve tray 2 arranged at the upper end of the base 1 to accept green semi-finished products , the rotating sieve tray 2 includes several layers of spiral grooves 3, and a screening groove 4 located above the spiral groove 3 and receiving the end of the spiral groove 3. The spiral groove 3 is provided with a mixed friction with the green semi-finished product. And remove the raw powder of its surface dust, the screening groove 4 is provided with a screening hole 5 for the raw powder to fall into the lower spiral groove 3, the end of the screening groove 4 is provided with a discharge groove 6, and the vibrator Drive the rotary sieve plate 2 to vibrate and drive the green semi-finished product to rotate upwards and output through the discharge chute 6.

In this embodiment, a controller connected to the vibrator is also included, and the controller can control the vibration frequency of the vibrator, and then control the amplitude and speed of the vibration of the rotating sieve tray 2 . The rotating sieve tray 2 is fixed on the base 1 by nuts.

As shown in 1, the spiral groove 3 has two layers, and the spiral groove 3 and the screening groove 4 are integrally formed. The spiral groove 3 and the screening groove 4 can be interlaced in the circumferential direction, or they can be butted in the circumferential direction. The shape of the screening hole 5 offered on the screening tank 4 can be circular or oval.

When in use, the raw body semi-finished product processed by the cutting machine directly enters the powder passing machine described in the utility model from the feeding chute, and an appropriate amount of raw powder is added into the spiral groove 3, and the vibrator drives the rotating sieve plate 2 to vibrate and drive the raw powder The semi-finished billet rotates upwards, from the bottom layer of the rotary sieve plate 2 to the upper layer. When passing through the spiral groove 3, it is mixed and rubbed with the raw powder used to remove the dust on its surface. When passing through the screening groove 4, it is attached to the surface of the semi-finished billet. The raw powder that rotates with it and enters the screening tank 4 falls into the lower spiral groove 3 through the screening hole 5 to realize recycling, and the green semi-finished product after the powder treatment is finally output through the discharge tank 6.

The utility model replaces the manual operation, greatly improves the work efficiency, reduces the workload of the workers, and reduces the production cost. Notch or broken phenomenon occurs, the structure is reasonable, the design is novel, and it is suitable for wide popularization and application.

Although the present utility model has been described in detail with reference to the above embodiments, it is apparent to those skilled in the art through this disclosure that the present utility model can be modified without departing from the principle and spirit scope of the present utility model defined by the claims.
