Description

Technical Field

[0001] This application relates to the technical field of screening equipment, and in particular to an automatic feeding screening machine. Background Technology

[0002] After the high-purity silver powder is prepared, it needs to be sieved using a sieve to form different grades of silver powder. The sieve used for sieving silver powder is generally an ultrasonic vibrating sieve.

[0003] Currently, Chinese patent CN214399016U discloses a metal powder airtight vibrating sieve device with an automatic feeding mechanism, including a main body and a base. A feeding cylinder and a storage hopper connected to the feeding cylinder are fixedly connected to the base. A screw rod is installed inside the feeding cylinder. The end of the screw rod is connected to a reducer fixed to the base, and the reducer is connected to a drive motor. A fixed plate is installed inside the storage hopper. The lower end of the fixed plate has a turntable. The turntable is connected to a stepper motor fixed to the top of the storage hopper through a shaft. The end of the feeding cylinder has a feeding port connected to the main body.

[0004] Because the powder in the feeding cylinder enters the main body directly through the feeding port, the feeding port of the feeding cylinder is directly connected to the main body. This results in a fixed height of the main body and the same screening levels, thus limiting its applicability. Utility Model Content

[0005] To improve applicability, this application provides an automatic feeding screening machine.

[0006] This application provides an automatic feeding screening machine, which adopts the following technical solution:

[0007] An automatic feeding screening machine includes an ultrasonic vibrating screen body, a fixed frame, and a material bin. The fixed frame is disposed on one side of the ultrasonic vibrating screen body, and the material bin is disposed on the fixed frame. It also includes a feeding mechanism, which comprises a vibrator, a pad, a transfer block, a first connecting component, a second connecting component, and a communicating component. The vibrator is disposed on the fixed frame, and the pad is disposed on the vibrating plate of the vibrator via the first connecting component. The transfer block has a transfer hole and is disposed on the pad via the second connecting component. One end of the transfer block is connected to the material bin via the communicating component, and the other end of the transfer block is connected to the ultrasonic vibrating screen body.

[0008] By adopting the above technical solution, when the number of vibrating screens in the ultrasonic vibrating screen body changes, a suitable pad is selected, and the pad is connected to the vibrating plate of the vibrator through the first connecting component. Then, the transfer block is connected to the pad through the second connecting component. The powder in the material bin enters the transfer hole of the transfer block through a connecting component, and then enters the ultrasonic vibrating screen body for screening through another connecting component under the vibration of the vibrator. Therefore, the feeding mechanism can adjust the position of the transfer block according to the number of vibrating screens in the vibrating screen body, thereby improving applicability.

[0009] Optionally, the pad includes a first fixing plate, a second fixing plate, and a third fixing plate. The first fixing plate is connected to the vibrating plate of the vibrator through the first connecting assembly. The second fixing plate is disposed on the second fixing plate, and the third fixing plate is disposed on the second fixing plate. The third fixing plate is connected to the transfer block through the second connecting assembly.

[0010] By adopting the above technical solution, the first fixing plate is installed on the vibration start-up vibrating plate through the first connecting assembly, and the transfer block is connected to the third fixing plate through the second connecting assembly; the height of the pad is determined according to the height of the second fixing plate.

[0011] Optionally, the first connecting assembly includes a first connecting bolt and a connecting nut, a first through hole is provided on the first fixing plate, a second through hole is provided on the vibrating plate of the vibrator, one end of the first connecting bolt passes through the first through hole and the second through hole, the connecting nut is threadedly connected to the first connecting bolt, and the vibrating plate of the vibrator and the first fixing plate are located between the nut of the first connecting bolt and the connecting nut.

[0012] By adopting the above technical solution, the end of the first connecting bolt away from its own nut passes through the first through hole on the first fixed plate and the second through hole on the vibrator plate. The first connecting bolt is threaded with a connecting nut, and the nut of the first connecting bolt itself abuts against the first fixed plate. The connecting nut abuts against the vibrator plate, thereby realizing the connection between the first fixed plate and the vibrator. The structure of the first connecting component is simple and easy to operate.

[0013] Optionally, the second connecting component includes a first connecting block, a limiting block, and a second connecting bolt. The first connecting block is disposed on the first fixing plate, the limiting block is disposed on the first fixing plate, and the transfer block has a limiting groove that matches the limiting block. The third fixing plate has a third through hole, and the transfer block has a first threaded hole. The second connecting bolt passes through the third through hole and is threadedly connected to the first threaded hole.

[0014] By adopting the above technical solution, after the first fixed plate is connected to the vibrator through the first connecting component, the limiting block is aligned with the limiting groove on the transfer block. Then, the transfer block is moved so that the rotating block abuts against the third fixed plate, and the limiting block enters the limiting groove. When the limiting block abuts against the side wall of the limiting groove, the second connecting bolt is threaded through the third through hole on the third connecting block and threaded into the first threaded hole on the transfer block, thereby connecting the transfer block to the third fixed plate. The second connecting component is not only simple and easy to operate, but the limiting block that cooperates with the limiting groove can realize the positioning of the transfer block, thus facilitating the connection of the second connecting bolt.

[0015] Optionally, the fixed frame is provided with a support mechanism, which includes a support block and a third connecting component. The support block is mounted on the fixed frame through the third connecting component, and the vibrator is mounted on the support block.

[0016] By adopting the above technical solution, when the number of vibrating screens in the ultrasonic vibrating screen body changes significantly, the position of the support block on the fixed frame can be adjusted first, and then the support block can be fixed on the fixed frame through the third connecting component; the support mechanism can facilitate the position of the vibrator and the transfer block, thereby improving applicability.

[0017] Optionally, the support block is provided with a reinforcing mechanism connected to the fixing frame. The reinforcing mechanism includes a reinforcing block, a toggle block, a spring, and a positioning bolt. The support block has a sliding hole, and the reinforcing block is slidably disposed in the sliding hole. The fixing frame has a reinforcing groove that engages with the reinforcing block.

The reinforcing block has a second threaded hole, and the positioning bolt passes through the fifth through hole and is threadedly connected to the second threaded hole.

[0018] By adopting the above technical solution, when it is necessary to adjust the position of the support block, firstly, the positioning bolt is no longer threaded into the second threaded hole. Then, the actuating block is moved, which drives the reinforcing block to move, so that the reinforcing block is fully extended into the sliding hole, and the spring will deform. Then, the support block is moved. After the position of the support block is determined, the actuating block is released, and the force of the spring restoring its elastic deformation drives the reinforcing block to move towards the fixed frame and engage with the reinforcing groove on the fixed frame. The reinforcement mechanism can improve the stability of the support block on the fixed frame.

The mounting block has a seventh through hole, and the support block has a fourth threaded hole. The second mounting bolt passes through the seventh through hole and is threadedly connected to the fourth threaded hole.

[0020] By adopting the above technical solution, the mounting block first contacts the base of the vibrator, then the first mounting bolt passes through the sixth through hole on the mounting block and is threaded to the third threaded hole on the base of the vibrator; then the mounting block contacts the support block, and finally the second mounting bolt passes through the seventh through hole on the mounting block and is threaded to the fourth threaded hole on the support block; the mounting assembly can realize the detachable connection between the vibrator and the support block.

The first reinforcing block is disposed on the mounting block, and the support block has a first slot that engages with the first reinforcing block. The second reinforcing block is slidably disposed on the support block, and the first reinforcing block has a second slot that engages with the second reinforcing block. The adjusting component is disposed on the support block and connected to the second reinforcing block.

[0022] By adopting the above technical solution, when the mounting block abuts against the support block, the first reinforcing block engages with the first slot on the support block, causing the adjusting component to drive the second reinforcing block to move, so that the second reinforcing block engages with the second slot on the first reinforcing block; the reinforcement mechanism can improve the stability of the mounting block on the support block.

[0023] Optionally, the adjustment assembly includes an adjustment shaft, a gear, and a rack. The adjustment shaft is rotatably mounted on the support block, and the gear is keyed to the adjustment shaft. The rack is mounted on the second reinforcing block and meshes with the gear.

[0024] By adopting the above technical solution, rotating the adjustment shaft causes the gear on the adjustment shaft to move the rack, which in turn causes the second reinforcing block to move; the adjustment component has a simple structure and is easy to operate.

[0025] Optionally, the connecting component includes a transition block, a cloth tube, and fasteners. The transition block is disposed on the transfer block, and the two ends of the transfer block are provided with the transition block.
