[0018] Example 1
[0019] like Figures 1 to 4 As shown, the present invention proposes a nail screening device, including a stabilizing base 1, a screening box 3, a sealing plate 403, and a material guiding mechanism; a vibrating frame 2 is vibratingly connected to the stabilizing base 1; multiple screening boxes 3 are provided, and the multiple screening boxes 3 are evenly installed on the inner wall of the vibrating frame 2; multiple screening ports 305 are provided at the bottom of the screening box 3, and the multiple screening ports 305 are distributed horizontally and vertically in a crisscross pattern; the size of the screening ports 305 on the multiple screening boxes 3 gradually decreases from top to bottom; a discharge port 303 is opened at the output end of the screening box 3; multiple sealing plates 403 are provided, and the multiple sealing plates 403 are adjustablely installed on the screening box 3; the sealing plates 403 correspond to the discharge ports 303; the material guiding mechanism consists of a moving frame 502, multiple sets of drop pipes 501 installed on the moving frame 502, and a material guiding cover 5 installed at the top of the drop pipes 501; the moving wheels at the bottom of the moving frame 502 are equipped with brakes; the input end of the material guiding cover 5 corresponds to the output end of the screening box 3.
[0020] Furthermore, the bottom of the vibration frame 2 is provided with multiple sets of lugs 101, and the stabilizer 1 is provided with multiple sets of uprights 102. The lugs 101 and the uprights 102 are slidably connected. Springs 103 are installed at the top and bottom of the lugs 101. The springs 103 are sleeved on the outside of the uprights 102. The end of the spring 103 away from the lugs 101 is connected to the top of the uprights 102 or the stabilizer 1. The bottom of the vibration frame 2 is provided with a vibration motor.
[0021] Furthermore, the screening box 3 consists of a screen frame and an inclined plate 304 installed at the bottom of the screen frame. Multiple screening ports 305 are evenly distributed on the inclined plate 304. The inclined plate 304 facilitates the subsequent discharge of the nails. The discharge port 303 is located at the discharge end of the screen frame. A guide seat 302 is installed at the top of the screen frame. The sealing plate 403 is slidably inserted into the guide seat 302. The guide seat 302 improves the stability of the connection between the sealing plate 403 and the screen frame.
[0022] Furthermore, the vibrating frame 2 is equipped with a driving mechanism, which drives multiple sets of sealing plates 403 to slide vertically along the screen frame. The driving mechanism includes a threaded rod 4, a lifting seat 401, and a connecting rod 402. The threaded rod 4 is driven to rotate by a motor installed on the vibrating frame 2. Multiple sets of lifting seats 401 are provided, and the multiple sets of lifting seats 401 are evenly threaded onto the threaded rod 4. One end of the connecting rod 402 is connected to the lifting seat 401, and the other end is connected to the top of the sealing plate 403. The sealing plate 403 slides into the screen frame.
[0023] Furthermore, the guide cover 5 is inclinedly set at the input end of the discharge pipe 501, and the diameter of the input end of the guide cover 5 is greater than the width of the output end of the screening box 3, so that the discharge pipe 501 and the screening box 3 do not contact each other.
[0024] In this embodiment, the movable frame 502 is moved around the vibrating frame 2 and the brake is locked to prevent the movable frame 502 from shifting. At this time, the guide cover 5 at the top of the discharge pipe 501 is located outside the output end of the screening box 3 but does not contact the screening box 3 to avoid interfering with the up-and-down vibration of the screening box 3. The processed nails of different lengths are placed in the uppermost screening box 3. The vibration motor is started by the controller to drive the vibrating frame 2 to vibrate, so that the vibrating frame 2 moves up and down along the upright 102 under the action of the spring 103, which achieves the vibration effect and thus vibrates and screens the nails. The nails are screened step by step through the screening ports 305 in multiple sets of screening boxes 3, so that nails of different lengths are stopped in different screening boxes 3. The discharge port 303 is blocked by the sealing plate 403, which can block the inside of the screen frame. The nails are thoroughly vibrated and screened to prevent them from being discharged through the outlet 303 without being screened, thus improving screening efficiency. After screening, the controller starts the motor to drive the threaded rod 4 to rotate, which in turn drives the lifting seat 401 to move upward along the threaded rod 4, and then drives the sealing plate 403 to move upward along the screen frame and guide seat 302. Due to the setting of the inclined plate 304, the nails inside the screening box 3 can move into the guide cover 5 under their own gravity, or the controller starts the vibration motor to vibrate slightly to drive the vibration frame 2 to vibrate, accelerating the transmission of the nails into the guide cover 5. After screening, the nails enter the discharge pipe 501 along the guide cover 5, and finally fall into the collection box below along the output end of the discharge pipe 501. The loading and unloading are more convenient and faster, and the nails can be screened step by step to improve screening efficiency.
[0025] Example 2
[0026] like Figures 2 to 4As shown, the nail screening device proposed in this utility model, compared with the first embodiment, has two sets of sockets 301 symmetrically arranged on the side wall of the screen frame, and multiple sets of mounting seats 201 symmetrically arranged on the inner wall of the vibrating frame 2. The two sets of sockets 301 are slidably inserted into the corresponding two sets of mounting seats 201, and a first fastening bolt is installed between the socket 301 and the mounting seat 201, which facilitates the disassembly of the screening box 3 and the vibrating frame 2 for maintenance; the end of the connecting rod 402 away from the sealing plate 403 is connected to the lifting seat 401 by a second fastening bolt.
[0027] In this embodiment, the movable frame 502 is moved away from the screening box 3, the second fastening bolt between the connecting rod 402 and the lifting seat 401 is removed, the connecting rod 402 is moved upward along the guide seat 302 until the connecting rod 402 is separated from the screening box 3, then the first fastening bolt between the socket 301 and the mounting seat 201 is removed, and the screening box 3 is moved horizontally along the mounting seat 201 and pulled out, so that the screening box 3 is separated from the vibrating frame 2, and the screening box 3 can be inspected and replaced.
[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
