Description

Technical Field

[0001] This utility model relates to the field of screening technology, and in particular to a screw thread rolling machine debris screening device. Background Technology

[0002] A screw is a tool used to fasten objects and machine parts; it is also called a screw, bolt, or screwdriver. It utilizes the physical and mathematical principles of inclined planes, circular rotation, and friction to progressively tighten objects and workpieces. Thread rolling machines are core equipment in the production of fasteners such as screws and bolts. They mainly use the relative movement of two threaded rolling plates to compress and plastically deform a metal bar, thereby producing threads. The fine metal particles and powder generated in this process are collectively referred to as thread rolling machine debris, which is a typical "process-related waste" in the fastener manufacturing industry. The different sizes of debris require separation of large and small sizes during the recycling process. However, current screening devices do not vibrate much, causing some debris to get stuck on the screen, leading to screen blockage and reduced efficiency. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned problems and shortcomings by proposing a screw thread rolling machine debris screening device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A screw thread rolling machine debris screening device includes a separating cylinder. The bottom outer wall of the separating cylinder is equipped with equally spaced support legs, and a guide cone is installed at the center of the bottom interior of the separating cylinder. The bottom outer wall of the separating cylinder has equally spaced discharge ports at the guide cone, and a screening structure is provided at the top of the inner wall of the separating cylinder. The screening structure includes a limiting ring installed at the top of the inner wall of the separating cylinder, a connecting groove equally spaced on the top outer wall of the limiting ring, an installation rod provided in the connecting groove, a screening disc placed on the top outer wall of the limiting ring, and an installation shell installed at the center of the top outer wall of the guide cone.

[0005] Furthermore, the bottom outer wall of the mounting rod is rotatably connected to a mounting plate, and the top outer wall of the mounting plate is equipped with a tension spring. The outer wall of the screening plate is provided with a sliding hole at the mounting rod, and the screening plate is slidably connected to the outer wall of the mounting rod through the sliding hole.

[0006] Furthermore, threaded grooves are provided on the outer walls of both ends of the mounting rod, and the mounting rod is threadedly connected to the center of the connecting groove. A limit nut is threadedly connected in the threaded groove at the top of the mounting rod.

[0007] Furthermore, the outer wall of the screening disc is provided with screening holes that are evenly distributed, and handles are welded to both ends of the top outer wall of the screening disc.

[0008] Furthermore, a dual-axis motor is installed on the inner wall of the mounting housing, and a lifting frame is installed on both ends of the output shaft of the dual-axis motor. Friction blocks are installed on the outer walls of the three ends of the lifting frame, and the outer walls of the friction blocks are slidably connected to the bottom outer wall of the limiting ring.

[0009] Furthermore, the dual-axis motor is connected to a switch via a wire, and the switch is connected to a power source via a wire.

[0010] The beneficial effects of this utility model are as follows: The lifting frame on the dual-shaft motor contacts and lifts the screening disc through friction blocks. The upward movement of the screening disc pulls the pull spring on the mounting plate. After the friction blocks stop contacting, the screening disc can be quickly returned to its original position. This process increases the screening range, making screening easier and avoiding clogging. The friction blocks on the lifting frames at both ends of the dual-shaft motor are installed alternately, which can increase the shaking frequency of the screening disc and make it easier to adjust the screening amplitude of the screening disc.

[0013] 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. Example

[0014] Reference Figure 1-3 As shown, a screw thread rolling machine debris screening device includes a separation cylinder 1. The bottom outer wall of the separation cylinder 1 is equipped with equally spaced support legs 2, and a guide cone 3 is installed at the center of the bottom interior of the separation cylinder 1. The bottom outer wall of the separation cylinder 1 is provided with equally spaced discharge ports 4 at the guide cone 3, and a screening structure 5 is provided at the top of the inner wall of the separation cylinder 1. The bottom outer wall of the mounting rod 8 is rotatably connected to the mounting plate 9, and the top outer wall of the mounting plate 9 is equipped with a tension spring 10. The outer wall of the screening plate 12 is provided with a sliding hole at the mounting rod 8, and the screening plate 12 is slidably connected to the outer wall of the mounting rod 8 through the sliding hole. Both ends of the mounting rod 8 have threaded grooves 11 on their outer walls, and the mounting rod 8 is threadedly connected to the center of the connecting groove 7. A limit nut 13 is threadedly connected in the threaded groove 11 at the top of the mounting rod 8. Large debris remains on the screening disc 12. Rotating the mounting rod 8 separates the threaded groove 11 at its bottom from the connecting groove 7. The screening disc 12 can be removed by the handle to collect the large debris, making it easy to use and collect. Example

[0015] Reference Figure 1-3 As shown, the screening structure 5 includes a limiting ring 6 installed at the top of the inner wall of the separation cylinder 1, a connecting groove 7 equally spaced on the top outer wall of the limiting ring 6, an installation rod 8 provided in the connecting groove 7, a screening disc 12 placed on the top outer wall of the limiting ring 6, and an installation shell 16 installed at the center of the top outer wall of the guide cone 3. The outer wall of the screening disc 12 is provided with screening holes 14 that are evenly distributed, and handles 15 are welded to both ends of the top outer wall of the screening disc 12. The inner wall of the mounting housing 16 is equipped with a dual-axis motor 17, and both ends of the output shaft of the dual-axis motor 17 are equipped with lifting frames 18. Friction blocks 19 are installed on the outer walls of the three ends of the lifting frames 18. The outer walls of the friction blocks 19 are slidably connected to the bottom outer wall of the limiting ring 6. The dual-axis motor 17 is connected to a switch via a wire, and the switch is connected to a power source via a wire. The lifting frame 18 on the dual-axis motor 17 contacts and lifts the screening disc 12 via a friction block 19. The upward movement of the screening disc 12 pulls the pulling spring 10 on the mounting plate 9. After the friction block 19 stops contacting, it can quickly return the screening disc 12 to its original position. This process increases the screening range, making screening easier while avoiding blockage. The friction blocks 19 are alternately installed on the lifting frames 18 at both ends of the dual-shaft motor 17, which can increase the shaking frequency of the screening disc 12 and facilitate the adjustment of the screening amplitude of the screening disc 12.

[0016] Working principle: During use, the collected debris is poured onto the screening disc 12 at the top of the separator 1. After the dual-shaft motor 17 starts, it drives the lifting frame 18 to rotate alternately. After the friction block 19 on the lifting frame 18 contacts the screening disc 12, the screening disc 12 is lifted and slides on the outer wall of the mounting rod 8. After the friction block 19 on the lifting frame 18 leaves the screening disc 12, the screening disc 12 quickly returns to the limiting ring 6 under the pull of the pulling spring 10. The debris on the screening disc 12 is turned over and screened in a cycle, which increases the turning range of the debris and avoids the debris from getting stuck in the screening hole 14 and clogging it. Small debris falls into the interior of the separator 1 through the screening hole 14. Under the guidance of the guide cone 3, the small debris is discharged and collected from the discharge port 4. Large debris remains on the screening disc 12. The mounting rod 8 is rotated so that the threaded groove 11 at its bottom end separates from the connecting groove 7. The screening disc 12 is removed by the handle to collect the large debris, which is convenient for use and collection.
