Technical Field
[0001] This utility model relates to the field of screening device technology, and in particular to a metal powder screening device with high screening efficiency. Background Technology
[0002] Metal powder is a solid substance made of metallic materials processed into fine particles through mechanical, chemical, or physical methods. It possesses a large specific surface area and good flowability. Metal powder is widely used in many industrial fields. Sieving of metal powder is an important process, primarily aimed at classifying powders according to particle size to ensure powder quality and uniformity, meeting the needs of specific applications. Therefore, sieving devices are required. A metal powder sieving device is a piece of equipment used for screening and classifying metal powders. Its main function is to separate particles of different sizes from the metal powder to obtain powder with the desired particle size distribution, ensuring powder uniformity and quality.
[0003] Most existing screening devices use fixed screens with non-adjustable aperture sizes. Different metal powders may require different particle size ranges, but screens with fixed apertures can only accommodate a specific particle size range and cannot meet other particle size requirements, resulting in insufficient product screening accuracy.
[0004] Therefore, there is an urgent need to provide a metal powder screening device with high screening efficiency to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is that most of the existing screening devices have fixed screens and the size of the screen holes cannot be adjusted.

[0007] The present invention is further configured such that: the aperture adjustment mechanism includes multiple limiting shells fixedly connected to the outer wall of the vibration frame, multiple fixing blocks are respectively provided in the multiple limiting shells, the multiple fixing blocks are fixedly connected to the vibration frame, and multiple driven sliders are slidably connected in the limiting shells.
[0008] Through the above technical solution, the hole formed between the active connecting block and the driven slider is enlarged or reduced, thereby controlling the size of the sieve hole diameter, ensuring that suitable particles are screened out, and meeting the different requirements for powder particle size distribution in the production process.
[0009] The present invention is further configured such that: a plurality of active connecting blocks are slidably connected inside the fixed block, a fixed rod is fixedly connected to the plurality of active connecting blocks, the fixed rod is slidably connected to the limiting housing, a fixed column is fixedly connected to one end of the fixed rod, a T-shaped plate is rotatably connected to the end of the vibration frame near the fixed column, a motion groove is opened at the end of the T-shaped plate away from the fixed column, and the driven slider is wedge-shaped.
[0010] The present invention is further configured such that: a moving column is slidably connected in the moving groove, the moving column is fixedly connected to the connecting rod, a plurality of limiting seats are fixedly installed on the outer wall of the vibration frame, the connecting rod is slidably connected to the plurality of limiting seats, a rack is fixedly installed at the end of the connecting rod away from the T-shaped plate, a gear is provided on one side of the rack, the gear meshes with the rack, one side of the gear is fixedly connected to the output end of the motor, and the side of the motor away from the gear is fixedly connected to the fixed box.
[0011] Through the above technical solution, the rotation of the motor drives the gear to rotate, the gear drives the rack to move the connecting rod, the moving column on the connecting rod drives the T-shaped plate to rotate through the moving groove, and the interaction between the two ends of the T-shaped plate and the fixed column drives the fixed rod to move.
[0012] The present invention is further configured such that: a plurality of upper fixing seats are fixedly connected to the lower surface of the fixing frame, a plurality of lower fixing seats are correspondingly arranged below the plurality of upper fixing seats, a vibration spring is fixedly connected between the upper fixing seats and the lower fixing seats, and the lower fixing seats are fixedly installed with the fixing base.
[0013] The present invention is further configured such that: a material dropping plate is fixedly installed between the fixed frames, and a material receiving frame is fixedly installed at one end of the material dropping plate.
[0014] With the above technical solution, the sieved powder can be collected into the receiving box through the discharge plate, eliminating the need for manual collection, making it convenient to use and highly automated.
[0015] The beneficial effects of this utility model are as follows:
[0016] This invention controls the size of the sieve aperture by setting an aperture adjustment mechanism at the lower end of the sieve hole. The aperture formed by the active connecting block and the driven slider is enlarged or reduced, thereby ensuring that suitable particles are screened out to meet the different requirements of powder particle size distribution in the production process. At the same time, it can avoid the situation where excessively large particles are stuck in the sieve hole and excessively small particles pass through the sieve hole, thereby improving the screening efficiency. When processing powders with a wide particle size distribution, adjusting the aperture helps to screen out more powders that meet the requirements and reduce the generation of unqualified materials.
