Description

Technical Field

[0001] This utility model relates to the field of mechanical conveying technology, and in particular to an automatic screw sorting mechanism. Background Technology

[0002] A screw is a tool that uses the physical and mathematical principles of the inclined plane, circular rotation, and friction to gradually fasten objects and machine parts. Screw is a general term for fasteners and is commonly used in everyday speech. Screws are a common type of fastener, widely used in machinery, electrical appliances, and buildings. They are generally made of metal or plastic, are cylindrical, and have grooves on their surface called threads. Before use, screws need to be arranged in an orderly manner.

[0003] Current automatic screw sorting mechanisms inevitably introduce screws of different sizes during production and transportation, affecting subsequent use after sorting. Additionally, screws can become contaminated with oil and iron filings during production, and excessive oil can attract dust, further impacting screw quality. Therefore, designing an automatic screw sorting mechanism is essential. Utility Model Content

[0004] The main purpose of this invention is to provide an automatic screw sorting mechanism that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic screw sorting mechanism includes a screening frame and a vibrating plate. A flexible screen is fixedly connected to the upper surface of the screening frame, and a conveyor belt is rotatably connected inside the screening frame. A limiting plate is fixedly connected to the bottom of the screening frame, and an inclined plate is fixedly connected to the bottom end of the limiting plate. An electromagnetic vibrator is fixedly connected to the bottom end of the vibrating plate, and a connecting rail is fixedly connected to one end of the slide of the vibrating plate. A support frame is fixedly connected to the bottom of the connecting rail, and a linear vibration rail is fixedly connected to the upper surface of the support frame.

[0007] In order to achieve the purpose of collecting large-sized screws, as an automatic screw sorting mechanism of this utility model, a collection tray is fixedly connected to one side of the screening rack, and a baffle is fixedly connected to the side of the screening rack near the collection tray.

[0008] In order to protect the motor, as an automatic screw sorting mechanism of this utility model, a protective cover is fixedly connected to one side of the screening rack, a motor is fixedly connected to the inner wall of the protective cover, and the output end of the motor is fixedly connected to the conveyor belt.

[0009] In order to achieve the purpose of cleaning oil stains and iron filings and other impurities from the surface of screws, as an automatic screw sorting mechanism of this utility model, a cleaning roller is rotatably connected to one side of the screening frame, a first gear is fixedly connected to one end of the cleaning roller, and a second gear is fixedly connected to the output end of the motor, with the first gear and the second gear meshing.

[0010] In order to remove impurities from the surface of the cleaning drum, as an automatic screw sorting mechanism of this utility model, a scraper is fixedly connected to the side of the screening frame near the cleaning drum, and a support leg is fixedly connected to the lower surface of the screening frame.

[0011] In order to achieve the purpose of collecting small-sized screws, as an automatic screw sorting mechanism of this utility model, the bottom of the support frame is fixedly connected to a support plate, and a collection hopper is provided on the upper surface of the support plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, through the arrangement of a flexible screen, conveyor belt, inclined plate, vibrating plate, and straight vibrating track, screws are placed on the flexible screen. Screws of the correct size will fall through the screen holes onto the conveyor belt, and as the conveyor belt moves, they will fall onto the inclined plate and enter the vibrating plate. The electromagnetic vibrator generates vibration, causing the screws in the vibrating plate to gradually move on the spiral upward track. Only screws with their heads facing upward can pass smoothly and enter the straight vibrating track, ultimately achieving automatic sorting and conveying of screws. The flexible screen is fixed to the screening frame through a special elastic connection device. When the screw head size is slightly larger than the screen hole, the flexible screen can elastically deform to allow the screw to pass through, while effectively blocking screws with incorrect posture or excessive size.

[0014] 2. In this utility model, through the arrangement of a motor, a cleaning roller, a scraper, a limiting plate, and a collecting hopper, when the motor drives the conveyor belt to rotate, it also drives the cleaning roller to rotate through the first gear. The cleaning roller can roughly remove impurities such as iron filings and oil stains from the screws, preventing impurities from affecting the quality of the screws. When the cleaning roller rotates, the scraper will scrape off the impurities on the surface of the cleaning roller, performing a simple cleaning of the cleaning roller, and the impurities will be blocked by the limiting plate and will not re-enter the screws. At the same time, the collecting hopper can collect small-sized screws falling from the linear vibration track, further improving the accuracy of screw screening. Attached Figure Description

[0024] In practical use, through the arrangement of flexible screen 2, conveyor belt 8, inclined plate 17, vibrating plate 6 and straight vibration track 19, screws are placed on flexible screen 2. Screws of the correct size will fall through the screen holes onto conveyor belt 8, and as conveyor belt 8 moves, they fall onto inclined plate 17 and enter vibrating plate 6. Electromagnetic vibrator 7 generates vibration, causing the screws in vibrating plate 6 to gradually move on the spiral upward track. Only screws with their heads facing upward can pass smoothly and enter straight vibration track 19, ultimately achieving automatic sorting and conveying of screws. Flexible screen 2 is fixed to screening frame 3 through a special elastic connection device. When the screw head size is slightly larger than the screen hole, flexible screen 2 can elastically deform to allow the screw to pass through, while effectively blocking screws with incorrect posture or excessive size.

[0025] In this embodiment, a collection tray 1 is fixedly connected to one side of the screening rack 3, and a baffle 15 is fixedly connected to the side of the screening rack 3 near the collection tray 1.

[0027] In this embodiment, a protective cover 5 is fixedly connected to one side of the screening rack 3, and a motor 14 is fixedly connected to the inner wall of the protective cover 5. The output end of the motor 14 is fixedly connected to the conveyor belt 8.

[0028] In practical use, the protective cover 5 can effectively protect the safety of the motor 14.

[0029] In this embodiment, a cleaning roller 10 is rotatably connected to one side of the screening rack 3, a first gear 12 is fixedly connected to one end of the cleaning roller 10, and a second gear 13 is fixedly connected to the output end of the motor 14.

[0031] In this embodiment, a scraper 11 is fixedly connected to the side of the screening frame 3 near the cleaning roller 10, and a support leg 4 is fixedly connected to the lower surface of the screening frame 3.

[0032] In practical use, the scraper 11 will scrape off the impurities on the surface of the cleaning roller 10 and perform simple cleaning of the cleaning roller 10.

[0033] In this embodiment, a support plate 20 is fixedly connected to the bottom of the support frame 9, and a collection hopper 21 is provided on the upper surface of the support plate 20.

[0034] In practical use, the collection bucket 21 can collect small screws falling from the linear vibration track 19 by means of the collection bucket 21.

[0035] Working principle: During use, screws are placed on the flexible screen 2. Screws of the correct size will fall through the screen holes onto the conveyor belt 8. Larger and incorrect screws will be collected in the collection tray 1. Qualified screws will fall onto the inclined plate 17 and enter the vibrating plate 6 as the conveyor belt 8 moves. Before the screws fall onto the inclined plate 17, they will pass through the cleaning roller 10. The cleaning roller 10 can roughly remove impurities such as iron filings and oil stains from the screws to prevent impurities from affecting the quality of the screws. The electromagnetic vibrator 7 generates vibration, which makes the screws in the vibrating plate 6 gradually move on the spiral upward track. Only screws with their heads facing upward can pass smoothly and enter the straight vibration track 19. The collection hopper 21 can collect small-sized screws falling from the straight vibration track 19. Qualified screws that have been sorted will complete the straight vibration track 19 and be collected for use.
