Description

Technical Field

[0001] This utility model relates to the field of screw processing equipment technology, and in particular to a rust-preventing dip-plating device for screws. Background Technology

[0002] Screws, as a common fastener, are widely used in various fields. In actual use, screws are often affected by environmental factors, such as humid air, moisture, and acidic or alkaline substances, which can lead to rust and corrosion, affecting their service life and performance. In order to improve the rust resistance of screws and extend their service life, rust prevention treatment is usually required. Dip plating is a commonly used rust prevention treatment method.

[0003] A Chinese patent (CN201192671Y) discloses an automatic spin-dip coating machine for screws. The machine places the screws to be coated into a feed hopper in a feeding device. The hopper is then raised and pushed into a housing using a push-pull device for rust-preventive paint coating. Simultaneously, a feed hopper on a tilting device is placed inside the feeding device and lowered. After coating, the feed hopper is pulled out using the push-pull device, and the coated screws are poured into a centrifugal device for rotation and agitation. This ensures the rust-preventive paint adheres evenly to the screw surface, achieving a good rust-preventive paint coating effect and improving product quality.

[0004] The filters in the circulating filtration system of the immersion plating equipment need to frequently handle metal particles and impurities in the immersion plating solution. After long-term use, they are prone to clogging, which leads to a decrease in circulation efficiency and may even affect the normal supply of the immersion plating solution. Utility Model Content

[0008] As a further technical solution of this utility model, multiple sets of grooves are equidistantly arranged in a ring on the upper and lower sides of the support column sidewall. The inner wall of the groove is rotatably connected to a support plate that matches the groove through a damping shaft, and the filter frame is fitted onto the support column surface and located on the unfolded support plate.

[0009] As a further technical solution of this utility model, an annular guide rail is fixedly connected to the top of the soaking tank, a slider is slidably connected to the annular guide rail, and a force-bearing rod located inside the soaking tank is rotatably connected to the soaking tank.

[0010] As a further technical solution of this utility model, the force-bearing rod is connected at equal intervals with multiple scraping teeth corresponding to the filter frame by bolts, and the scraping teeth are located inside the filter frame and in contact with its bottom.

[0013] This utility model provides a rust-preventing dipping and plating device for screws, which has the following advantages compared with the prior art:

[0014] This design discloses an immersion plating device for rust prevention of screws. A batch of screws is placed flat inside a filter frame. A support column is then fixed inside an immersion tank via a limiting block and a limiting groove. A tray is then sequentially flipped and unfolded via a damping shaft, allowing the filter frame containing the screws to be placed over the support column from the top and positioned by the tray. A large amount of immersion plating solution is then injected into the immersion tank, submerging the screws. The plating solution fully penetrates and contacts the screw surface, forming a dense rust-preventive coating through a chemical reaction. Metal particles and impurities generated during the immersion process are neutralized. If the metal particles fall to the bottom of the soaking tank or are filtered by the filter frame, the circular electric slide rail is activated to drive the collar to rotate, causing the collar to drive the roller to rotate. The roller contacts the soaking tank and rolls, thereby adsorbing the metal particles that have fallen to the bottom of the soaking tank. As the roller rolls, it contacts the first filter screen, which can suck away the metal particles on the first filter screen to prevent the first filter screen from clogging. After the screw is dipped in the plating solution, the solenoid valve can be opened to discharge the plating solution and unload the screw. When the liquid is discharged, it passes through the double-layer filtration of the first and second filter screens, so that the plating solution can be recycled. Attached Figure Description

[0023] Please see Figure 2A limiting groove is provided at the top of the connecting shaft, and a limiting block is fixedly connected to the bottom of the support column 7. The limiting groove and the limiting block are engaged. Multiple sets of grooves 16 are provided in a ring at equal intervals on the upper and lower sides of the side wall of the support column 7. The inner wall of the groove 16 is rotatably connected to a support plate 18 that matches the groove 16 through a damping rotating shaft 22. The filter frame 15 is fitted on the surface of the support column 7 and is located on the unfolded support plate 18.

[0024] Please see Figures 2-5 A ring guide rail 11 is fixedly connected to the top of the soaking tank 1. A slider 12 is slidably connected to the ring guide rail 11. A force rod 17 located inside the soaking tank 1 is rotatably connected to the soaking tank 1. Multiple scraper teeth 14 corresponding to the filter frame 15 are equidistantly connected to the force rod 17 by bolts. The scraper teeth 14 are located inside the filter frame 15 and contact its bottom. A rotating shaft 8 is snapped onto the top of the support column 7. A handle 9 is fixedly connected to the top of the rotating shaft 8. A sliding groove 23 is opened on the side wall of the rotating shaft 8. A connecting rod 10 is slidably connected in the sliding groove 23. A round hole is opened at the end of the connecting rod 10 away from the sliding groove 23. The round hole engages with the force rod 17. The force rod 17 passes through the slider 12 and is fixed by a nut.

[0025] The working principle of this utility model is as follows: A batch of screws are placed flat inside the filter frame 15. Then, the support column 7 is fixed inside the soaking tank 1 by the limiting block and the limiting groove. At this time, the tray 18 is flipped and unfolded in sequence by the damping shaft 22. The filter frame 15 containing the screws is placed on the surface from the top of the support column 7 and positioned by the support plate 18. At this time, a large amount of immersion plating solution can be injected into the soaking tank 1 to submerge the screws. The immersion plating solution can fully penetrate and contact the surface of the screws, forming a dense anti-rust coating on the surface of the screws through a chemical reaction. Metal particles and impurities generated during the immersion plating process fall to the bottom of the soaking tank 1. Alternatively, the solution can be filtered by the filter frame 15. At this time, the annular electric slide rail is activated to drive the collar 20 to rotate, causing the collar 20 to drive the roller 21 to rotate. The roller 21 contacts the soaking tank 1 and rolls, thereby adsorbing the metal particles that fall to the bottom of the soaking tank 1. The roller 21 contacts the first filter screen 13 during rolling, which can suck away the metal particles on the first filter screen 13 and prevent the first filter screen 13 from clogging. After the screw is dipped, the solenoid valve can be opened to discharge the dipping solution and unload the screw. When the liquid is discharged, it passes through the double-layer filtration of the first filter screen 13 and the second filter screen 19, so that the dipping solution can continue to be recycled.

[0026] Before placing the filter frame 15, tighten the bolts to rotate the force rod 17, causing multiple scraper teeth 14 to rotate synchronously and fit against the inner wall of the soaking tank 1, avoiding obstruction of the filter frame 15. This facilitates the installation of the filter frame 15 onto the surface of the support column 7. After installation, the position of the scraper teeth 14 can be adjusted by sliding the force rod 17 up and down on the slider 12. Then, rotate it to position it inside the filter frame 15. At this point, let the force rod 17 slide down so that the scraper teeth 14 contact the bottom of the filter frame 15. Finally, tighten the bolts to position the force rod 17. Then, insert the rotating shaft 8 into the top of the support column 7 so that the connecting rod 10 is directly above the force rod 17. Then, slide the connecting rod 10 and lock it onto the surface of the force rod 17. At this point, when you hold the handle 9 and rotate the rotating shaft 8, the connecting rod 10 will drive multiple force rods 17 to rotate synchronously on the annular guide rail 11, which can turn over the screws inside the filter frame 15, making it soak more thoroughly.
