The utility model discloses a gradient density eiderdown sorting device relates to eiderdown processing equipment technical field, the utility model discloses a box body, the box body rear side fixedly connected with screening mechanism, the box body top fixedly connected with scattering mechanism. The utility model screening mechanism three layer inclined sieve plate design, realizes gradient sorting through different aperture, solves the problem that single -layer sieve plate can only simple screening, cannot fine grading, can accurate separation different density's eiderdown, and the vibrating mechanism of cam drive of inclination structure cooperation, utilize gravity and vibration double -action enhancement eiderdown fluidity, avoid the accumulation jam of planar formula sieve plate because of poor mobility, promote the sorting efficiency greatly, double -shaft motor passes bevel gear, worm and worm wheel drive cam rotation, and the spring reset is combined, then can make the stable and regular vibration of the sieve plate of board frame drive, ensure that eiderdown is evenly distributed on the screen surface, fully screens, further improve the sorting accuracy.

This invention discloses a segmented drum screen device for mineral processing, comprising a base, a storage box, a screening machine, and a mounting frame. The storage box and mounting frame are both fixedly connected to the base, and the screening machine is inclinedly positioned on top of the storage box. The screening machine includes a casing, a main shaft, and several circular screens. The main shaft is rotatably connected to the casing. Several connecting rods are fixedly connected between the circular screens and the main shaft. Several screen holes are evenly distributed on the circular screens. Baffles are rotatably connected between adjacent circular screens, and discharge holes are provided on the baffles. A drive gear is fixedly connected to one end of the main shaft, and a drive reduction motor is fixedly connected to the top of the mounting frame. A receiving box is provided inside the storage box, located below the corresponding circular screen. This invention employs a mechanical structure for mineral particle size classification. The inclination degree controls the mineral's movement speed, and the baffles control the classification and discharge speed, ensuring good classification results for minerals at each stage and improving the efficiency of mineral processing and classification operations.

The application relates to a rubber particle screening mechanism, which comprises a screening box, the inside of the screening box is provided with a first screening frame and a second screening frame from top to bottom, the inner bottom of the screening box is provided with a collecting box, the side wall of one end of the screening box is provided with a first discharge port and a second discharge port, the outer side of the first discharge port and the second discharge port is provided with a first material guide hopper and a second material guide hopper, and the top of the screening box is further provided with a feeding hopper. Through the work of a driving motor, the shaft rod drives the cam to vibrate the first screening frame and the second screening frame under the action of a first transmission wheel, a second transmission wheel and a transmission belt, and under the action of a spring rod, the first screening frame and the second screening frame can well vibrate and screen rubber particles, so that the screening of the rubber particles is more sufficient, and the screening quality is improved.

This invention discloses an automated welding device for steel structure production, including a fixed frame with a moving unit at its top; and a welding unit mounted on the moving unit, including a support frame and a welding torch installed at the bottom of the support frame. This invention uses a flux output unit composed of a material bin, a separation mechanism, and a double-discharge component. It can classify recycled residual flux, retaining reusable flux, which is then further separated into fine and coarse materials for separate storage. The double-discharge component can sequentially output the flux in layers, forming a layered structure of fine material at the bottom and coarse material at the top. The fine material at the bottom fully fills the weld gap space, tightly wraps the welding wire end, and strictly prevents air intrusion. The coarse material at the top forms a stable protective slag shell, enhancing insulation and permeability, and smoothly expelling arc gases and water vapor. This effectively avoids defects such as incomplete penetration, incomplete fusion, open welds, and voids, greatly improving weld formation quality and welding reliability.
