Description

Particle shaker

The invention relates to a particle sifting machine, in particular to a powder or granule shaker applied to various materials of micron size, which can shake the screen left and right and shake up and down to filter the raw materials of the micro particles to avoid Screen clogging and low raw material agitation occur, achieving the ability to fully screen raw materials, greatly increasing the overall utilization rate of raw materials, and creating an innovative designer of particle sifting machines with more practical functions in their overall application. .

According to the general swinging machine, the moving stroke of the screen is generally in the form of shaking left and right, and in order to prevent the screen from being blocked, some will hit the upper part of the screen with heavy objects to generate vibration; The net efficiency power motor often needs to generate a higher number of shaking at a higher rotation speed, which also increases the wear rate of the raw material on the screen and increases the wear rate, and the upper and lower amplitudes of the weight hitting the screen are too small, so the screen The increased probability of blocking will make the raw materials not completely screened. If the force is too large when striking, the impact force generated by the raw materials will also damage the screen. The smaller the aperture, the more difficult the production is due to the difficulty in making the screen. It is more expensive than the general screen, and it also causes an increase in the cost of its use.

Among them, please refer to the "Eccentric Automatic Reversion Screening Machine" No. 510255 announced on November 11, 1991, which is provided with a bearing fixed by a vibration-filtering box supported by an elastic element and driven by a motor. a rotating shaft, wherein the vibrating device comprises a turntable fixed to the rotating shaft and having a flange portion, and is provided on the disk surface of the turntable with a movable block back The guide rail of the slide groove provided by the surface is now made to have a large part at the lower end of the transfer block, and an elongated hole is arranged in the middle so that the flange of the turntable can be worn out here, and then fixed to the convex by the stop sleeve. At the end of the edge, at the same time, two suspension brackets with a plurality of springs are suspended on the turntable, and the ends of the springs are hooked on both sides of the lower end of the lower portion of the transfer block, and the motor is rotated. The centrifugal force generated and the eccentricity of the weight of the transfer block enable the smashing block to generate an impact force to drive the screen, and the mesh spring and the transfer block link spring absorb the force of the smash and then automatically return the smashing block. The vibration is generated by the cycle; however, in order to make the smashing block, the motor power used by the structure needs to be large or not, and it is not only energy-consuming, but also relatively incapable of controlling the vibration force, which is easy to cause the screen. Damage to the net.

Please refer to M341366 "Vibration Screening Machine with Ring Shaped Sheet" announced on May 21, 1996. This structure is to mount the motor to the center of the ring-shaped body and use the motor to drive the eccentric weight. The object generates a vibration source, and then the upper screen is vibrated for filtering by the transmission and amplification of the ring-shaped sheet and the spring; however, the structure needs to transmit vibration by the ring-shaped sheet, so that it has a larger one. The volume, coupled with its strong vibration strength, can easily cause damage to the screen, which results in improved space for its overall application.

In addition, please refer to M351746 "Screening Machine" announced on March 1, 1998. The structure is connected by a movable connecting rod or spring and drives a weight eccentric wheel via a motor and belt. Vibration is generated; then, the structure is complicated and inconvenient in the overall structural design due to the need to use a belt drive and a complicated connecting rod to connect the screen. It is also inconvenient to replace screens of different sizes, so that there is room for improvement in the overall implementation.

The reason is that the inventor has in view of this, and has been researching and improving the existing structure for many years in the rich design and development and practical production experience of the relevant industry, thus inventing a particle sifting machine for the purpose of achieving better practical value. By.
