Description

A bolt screening device Technical Field

[0001] This utility model relates to the field of bolt screening technology, and in particular to a bolt screening device. Background Technology

[0002] Bolts are a common type of mechanical part, widely used in many key fields such as aerospace, automobile manufacturing, construction engineering, and electronic equipment. Currently, in the bolt manufacturing process, bolts of different specifications are mixed together, so it is necessary to classify and screen these bolts to facilitate subsequent classification and packaging.

[0003] Application No. 202420718220.7 discloses a high-efficiency bolt screening machine, including a collection box. A screening cylinder, penetrating the collection box and rotatably connected to the penetrating portion via a bearing, is disposed at the upper middle of the collection box. A screening plate is fixedly connected inside the screening cylinder. A mounting frame, fixedly connected to the collection box, is disposed above the screening cylinder. A circular plate is disposed inside the screening cylinder, with fixed rods fixedly connected to both sides of the circular plate and fixedly connected to the inside of the screening cylinder. A second rotating rod, penetrating the circular plate and the mounting frame and rotatably connected to the penetrating portion via a bearing, is disposed inside the screening cylinder. A first rotating rod, penetrating the mounting frame and rotatably connected to the penetrating portion via a bearing, is disposed on one side of the second rotating rod. Drive wheels are fixedly connected to the surfaces of both the first and second rotating rods. This high-efficiency bolt screening machine can improve the efficiency of bolt screening and is quite practical.

[0004] The above solution has shortcomings in use. The bolts may form a bridging phenomenon inside the screen holes on the screening plate, which will prevent subsequent bolts from passing through. This requires manual unblocking of the screen holes. Manual unblocking requires gradually finding the stuck points of the bolts and removing them. If multiple screen holes are blocked at the same time, the unblocking time will increase exponentially, thereby greatly increasing the equipment downtime and significantly reducing screening efficiency. To address this, we provide a bolt screening device. Summary of the Invention

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] As shown in Figures 1, 2, and 3: A bolt screening device includes a frame 1, a screening cylinder 2 installed on one side of the frame 1, a screening plate 3 inside the screening cylinder 2, and screening holes evenly distributed on the screening plate 3. After the bolt is added into the screening cylinder 2, it will be above the screening plate 3. A stirring assembly 4 is installed inside the screening cylinder 2. The stirring assembly 4 includes a motor 401 installed on the top and bottom surfaces of the frame 1. The output end of the motor 401 is fixedly connected to a rotating rod 402, and the bottom end of the rotating rod 402 is fixedly connected to... A push plate 403 is connected, and the operation of the motor 401 can drive the rotating rod 402 to rotate. The rotating rod 402 will drive the push plate 403 to rotate, and the push plate 403 will push the bolts to flow above the screening plate 3, so that some bolts can fall from above the screening plate 3. The outer surface of the rotating rod 402 is rotatably connected to the positioning plate 404. The other end of the positioning plate 404 is connected to the frame 1. The positioning plate 404 can connect the rotating rod 402 and the frame 1, further improving the stability of the rotating rod 402 when rotating.

[0026] As shown in Figure 1: Two covers 6 are provided above the screening cylinder 2. Each cover 6 has a handle on its upper surface. The covers 6 can be used to seal the top of the screening cylinder 2 to prevent bolts from flying out and accidentally injuring the staff. At the same time, the covers 6 will not affect the rotation of the rotating rod 402. A collection box 7 is placed on the top of the bottom of the frame 1 and is located directly below the screening cylinder 2. The collection box 7 can be used to collect the screened bolts.

[0027] As shown in Figures 1 and 4: A clearing component 5 is provided on one side of the screening cylinder 2. The clearing component 5 includes a circular plate 501 disposed on one side of the screening cylinder 2, and top rods 502 are evenly installed on the upper surface of the circular plate 501. The clearing component 5 also includes an adjustment structure disposed outside the screening cylinder 2 for allowing the top rods 502 to rotate and then rise to clear the screening plate 3. The adjustment structure of the clearing component 5 includes a motor 503 installed on the outer surface of the screening cylinder 2. A rotating shaft 504 is fixedly connected to the output end of the motor 503. A support plate 505 is fixedly connected to the bottom end of the rotating shaft 504. Two sets of electric push rods 506 are installed on the upper surface of the support plate 505. The telescopic ends of the electric push rod 506 are connected to the bottom surface of the circular plate 501. When the motor 503 is working, it will drive the rotating shaft 504 to rotate. At the same time, the support plate 505 will rotate. The support plate 505 will drive the electric push rod 506, the circular plate 501 and the top rod 502 to rotate 180 degrees to be below the screening cylinder 2. Then, the electric push rod 506 is controlled to extend. The circular plate 501 will drive the top rod 502 to rise. The top rod 502 will gradually insert into the screening hole on the screening plate 3. The bolt inside the screening hole will be gradually pushed out. The unblocking work of the screening plate 3 can be completed in one go, further reducing downtime and greatly improving screening efficiency.

[0028] As shown in Figure 4: A reinforcing plate 507 is rotatably connected to the outer surface of the rotating shaft 504. One side of the reinforcing plate 507 is connected to the outer surface of the screening cylinder 2. The reinforcing plate 507 can be used to connect the rotating shaft 504 and the screening cylinder 2, further improving the stability of the rotating shaft 504 when it rotates. A hanging plate 508 is fixedly connected to the outer surface of the rotating shaft 504. The bottom end of the hanging plate 508 is connected to the upper surface of the support plate 505. The hanging plate 508 can provide a certain pulling effect on the support plate 505, so that the support plate 505 remains stable and ensures that the top rod 502 and the screening hole of the screening plate 3 are vertically aligned.

[0029] Working principle: When it is necessary to unclog the screening plate 3, the motor 503 is activated, which drives the rotating shaft 504 to rotate. At the same time, the support plate 505 rotates, which in turn drives the electric push rod 506, the circular plate 501, and the top rod 502 to rotate 180 degrees to the bottom of the screening cylinder 2. Then, the electric push rod 506 is extended, and the circular plate 501 drives the top rod 502 to rise. The top rod 502 gradually inserts into the screening hole on the screening plate 3, and the bolts inside the screening hole are gradually pushed out. This can complete the unclogging of the screening plate 3 in one go, further reducing downtime and greatly improving screening efficiency.
