Description

Technical Field

[0001] This utility model relates to the field of bolt screening, specifically a centrifugal bolt high-efficiency screening device. Background Technology

[0002] In many industries such as machinery manufacturing and construction, bolts are important standard parts, and the accuracy of their specifications directly affects product quality and engineering safety. Therefore, efficient and accurate screening of bolts of different specifications has become a key link in the production and processing process.

[0003] Currently, most common bolt sorting methods on the market rely on manual sorting or simple mechanical sorting equipment. Manual sorting is inefficient, and long working hours can easily lead to worker fatigue, resulting in sorting errors and making it difficult to meet the needs of large-scale production. On the other hand, some existing mechanical sorting equipment has an unreasonable structural design. For example, during the bolt conveying process, there is a lack of effective guiding structure, which makes bolts prone to jamming and accumulation, affecting sorting efficiency. Furthermore, the sorting components are often fixed and cannot be adjusted, making it impossible to flexibly adapt to the sorting requirements of bolts of different specifications. The sorting accuracy is limited, resulting in poor sorting results.

[0004] In addition, the equipment is not stable enough, and it is prone to shaking during the screening process, which further affects the accuracy and efficiency of screening. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a centrifugal bolt high-efficiency screening device.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a centrifugal bolt high-efficiency screening device, including a base and a vertical cylinder. The top of the base is fixed with the vertical cylinder, and a drive motor is fixed at the center of the bottom of the vertical cylinder. A centrifugal disc is fixed at the output end of the drive motor. The centrifugal disc is rotatably connected to the vertical cylinder. A spiral support plate is fixed on the inner wall of the vertical cylinder. A support frame is fixed on one side wall of the vertical cylinder. An adjusting component is fixed inside the support frame. A vertical rod is fixed at the bottom of the adjusting component. A blocking disc is fixed at the bottom of the vertical rod. An adjusting frame is slidably connected to the outer wall of the vertical rod. A blocking component is rotatably connected inside the adjusting frame.

[0007] Furthermore, multiple rectangular protrusions are fixed at equal intervals around the top edge of the centrifugal disc.

[0008] Furthermore, the adjusting component includes a threaded block, which is fixed inside the support frame. A threaded rod is threadedly connected inside the threaded block. The bottom end of the threaded rod is fixedly connected to the vertical rod, and a turntable is fixed to the top end of the threaded rod.

[0009] Furthermore, the adjusting frame is composed of a sleeve and a rotating plate. The rotating plate and the sleeve are connected by a shaft. A torsion spring is provided on the outer wall of the shaft, and a limit member is provided at the position of the shaft.

[0010] Furthermore, the blocking assembly includes a rotating rod, which is rotatably connected inside the rotating plate of the adjusting frame, and a baffle is fixed at the bottom end of the rotating rod.

[0011] The beneficial effects of this utility model are:

[0012] Stable conveying structure: By setting anchor bolt mounting holes in the base, the equipment can be firmly fixed to the working ground, ensuring the stability of the screening process. The inner wall of the vertical cylinder is polished, and with the rectangular convex ridge and spiral support plate at the top of the centrifugal disc, the centrifugal disc rotates at high speed under the drive motor, causing the bolts to undergo centrifugal motion. Under the action of centrifugal force and gravity, the bolts rise smoothly along the spiral support plate. Compared with traditional screening methods, this greatly improves the bolt conveying efficiency, and the conveying process is stable, reducing problems such as bolt jamming and slippage, ensuring continuous and efficient screening work.

[0013] Flexible and adjustable screening components: The design of the adjustment component enables flexible adjustment of the height of the blocking component. By rotating the turntable at the top of the threaded rod, the operator can move the vertical rod up and down, thereby precisely adjusting the position of the adjustment frame and the blocking component to meet the screening needs of bolts of different specifications. The sleeve of the adjustment frame and the vertical rod slide well together. The rotating plate, through the synergistic action of the shaft, torsion spring and limiter, can maintain a specific angle when there is no external force, and can limit the rotation range, ensuring the stability and reliability of the blocking component.

[0014] Screening function: In the blocking component, the rotating rod drives the baffle to screen the rising bolts. Bolts with larger diameters are blocked by the baffle and fall from one side of the vertical cylinder into the storage box, while bolts with smaller diameters fall from the other side. This achieves the separation and screening of bolts of different specifications, effectively avoiding the errors and inefficiencies of manual screening, improving the accuracy and efficiency of bolt screening, meeting the needs of efficient bolt screening in industrial production, reducing production costs, and improving production efficiency.

[0021] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0022] See Figures 1-5 This is a schematic diagram of the structure of a centrifugal bolt high-efficiency screening device, including a base 1 and a vertical cylinder 2. Anchor bolt mounting holes are provided at the four corners of the base 1 for easy fixing of the device to the working ground. The vertical cylinder 2 is fixed to the top of the base 1. The vertical cylinder 2 is a cylindrical structure with a polished inner wall to reduce friction on the bolts during the screening process. A drive motor 3 is fixed at the center of the bottom of the vertical cylinder 2. The drive motor 3 is a three-phase asynchronous motor. A centrifugal disc 4 is fixed to the output end of the drive motor 3. The centrifugal disc 4 is rotatably connected to the vertical cylinder 2. The centrifugal disc 4 is a circular disc structure with multiple rectangular protrusions evenly spaced around its top edge. These protrusions drive the bolts to perform centrifugal motion when the centrifugal disc rotates, causing them to rise along the inner wall of the vertical cylinder. A spiral support plate 5 is fixed to the inner wall of the vertical cylinder 2. The spiral support plate 5 is made of stainless steel and ensures that the bolts rise smoothly along the spiral support plate under the action of centrifugal force and their own weight.

[0023] A support frame 6 is fixed to one side wall of the vertical cylinder 2 to stably support the adjusting component. The adjusting component, including a threaded block 7, is fixed inside the support frame 6. The threaded block 7 has a standard internal thread that mates with the threaded rod 8. The threaded rod 8 is connected to the threaded block 7 internally. The bottom end of the threaded rod 8 is fixedly connected to the vertical rod 9. A turntable is fixed to the top end of the threaded rod 8. The surface of the turntable is provided with anti-slip texture to facilitate manual rotation of the threaded rod 8 by the operator. By rotating the turntable, the threaded rod 8 moves up and down within the threaded block 7, thereby adjusting the height of the vertical rod 9. The bottom end of the threaded rod 8 is fixed to the vertical rod 9, and its surface is smooth to ensure that the adjusting frame 11 can slide smoothly on its outer wall. A blocking disc 10 is fixed to the bottom end of the vertical rod 9. The blocking disc 10 is a circular disc structure used to block the bolts that fall during the ascent, causing them to fall into the vertical cylinder 2.

[0024] An adjusting frame 11 is slidably connected to the outer wall of the vertical rod 9. The adjusting frame 11 is composed of a sleeve and a rotating plate. The sleeve is made of stainless steel tube with a smooth inner wall, which forms a good sliding fit with the outer wall of the vertical rod 9. The rotating plate is connected to the sleeve through a shaft. A torsion spring is provided on the outer wall of the shaft. The torsion spring can keep the rotating plate at a specific angle when it is not subjected to external force. A limiter is provided at the position of the shaft. The limiter is used to limit the rotation angle range of the rotating plate and prevent it from rotating excessively.

[0025] The adjusting frame 11 is internally connected to a blocking assembly, which includes a rotating rod 12. The rotating rod 12 is rotatably connected inside the rotating plate of the adjusting frame 11 and is installed with a bearing to reduce rotational friction. A baffle 13 is fixed at the bottom end of the rotating rod 12. The baffle 13 is a rectangular plate structure used to block and screen bolts under the drive of the rotating rod 12. Bolts with larger diameters are blocked and fall from one edge of the vertical cylinder 2 into the storage box, while bolts with smaller diameters fall from the other edge of the vertical cylinder after passing through the baffle 13, thus completing the screening work.

[0026] When using this utility model:

[0027] The bolts to be screened are placed inside the vertical cylinder 2. The drive motor 3 is started, and the three-phase asynchronous motor drives the centrifugal disc 4 to rotate at high speed. During the rotation, the rectangular protrusion at the top of the centrifugal disc 4 drives the bolt to make centrifugal motion, so that the bolt rises along the inner wall of the vertical cylinder 2 under the action of centrifugal force. Since the inner wall of the vertical cylinder 2 is fixed with a spiral support plate 5 made of stainless steel plate, the bolt will continue to be pushed under the combined action of centrifugal force and its own weight, and can rise steadily along the spiral support plate 5.

[0028] When the bolt rises to the blocking plate 10, the blocking plate 10 will block the bolts that are stacked during the rise, causing them to fall into the vertical cylinder 2, ensuring that the bolts continue to rise in a relatively orderly manner. At the same time, the operator can rotate the turntable with anti-slip texture at the top of the threaded rod 8 to move the threaded rod 8 up and down in the threaded block 7, thereby adjusting the height of the vertical rod 9, and thus adjusting the position of the adjusting frame 11 and the blocking component.

[0029] The sleeve of the adjusting frame 11 slides smoothly on the outer wall of the vertical rod 9. The rotating plate and the sleeve are connected by a shaft. The torsion spring on the outer wall of the shaft keeps the rotating plate at a specific angle when there is no external force. The limiting component restricts the rotation angle of the rotating plate. When the bolt continues to rise to the blocking component inside the adjusting frame 11, the baffle 13 at the bottom of the rotating rod 12 plays a role. Bolts with larger diameters will be blocked by the baffle 13 and fall from one side edge of the vertical cylinder 2 into the storage box, while bolts with smaller diameters can pass through the baffle 13 and fall from the other side edge of the vertical cylinder 2, thus achieving efficient screening of bolts of different specifications.
