Description

Technical Field

[0001] This utility model relates to the field of screw processing technology, and in particular to a screw hot-dip galvanizing equipment. Background Technology

[0002] Screws, as commonly used fasteners, are prone to corrosion in outdoor and humid environments, affecting their service life and safety. Hot-dip galvanizing is a key process to improve the corrosion resistance of screws. By immersing the screws in molten zinc, a zinc alloy coating is formed on their surface, achieving long-term protection.

[0003] Existing hot-dip galvanizing equipment for screws requires the screws to air dry and cool naturally after galvanizing. While this achieves the desired drying and cooling process, it is relatively slow, thus affecting production efficiency. Therefore, it is necessary to design a new hot-dip galvanizing equipment for screws. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hot-dip galvanizing equipment for screws.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hot-dip galvanizing equipment for screws, comprising a galvanizing tank, a lifting mechanism at the rear end of the galvanizing tank, a swaying mechanism at the lower end of the lifting mechanism, a connecting component at the lower end of the swaying mechanism, the swaying mechanism being connected to a holding frame via the connecting component, the swaying mechanism being used to drive the holding frame to sway; the lifting mechanism being used to drive the holding frame to move up and down; a heating element being installed at the bottom of the galvanizing tank, and a drying mechanism being provided on the upper right side of the galvanizing tank, the drying mechanism being used to dry and cool the screws inside the holding frame.

[0006] As a further description of the above technical solution: The lifting mechanism includes a fixed plate, a first motor, a lead screw, a movable frame, and a cantilever. The rear end of the galvanizing tank is fixedly connected to the fixed plate and the first motor. There are two fixed plates. The lead screw is rotatably connected inside the fixed plate. The movable frame is threadedly connected to the lead screw. The upper end of the movable frame passes through the upper fixed plate and is slidably connected to the fixed plate. The upper end of the movable frame is fixedly connected to the cantilever. The output end of the first motor is fixedly connected to the lead screw.

[0007] As a further description of the above technical solution: The swaying mechanism includes a second motor, a disc, a slide rod, a movable seat, a slide rail, and a sliding hole. The upper end of the cantilever is fixedly connected to the second motor, the output end of the second motor passes through the cantilever and is rotatably connected to the cantilever, the output end of the second motor is fixedly connected to the disc, and the lower end of the disc is fixedly connected to the slide rod. The lower end of the cantilever is fixedly connected to the slide rail, the movable seat is slidably connected to the slide rail, the upper surface of the movable seat has a sliding hole, the slide rod is located inside the sliding hole and is slidably connected to the sliding hole.

[0008] As a further description of the above technical solution: The slide bar is located at the edge of the disk, and the axis of the slide bar is not on the same straight line as the axis of the disk.

[0009] As a further description of the above technical solution: The connecting assembly includes a plug-in socket, a connecting bracket, and a locking screw. The lower end of the movable seat is fixedly connected to the plug-in socket, and the connecting bracket is inserted into the plug-in socket. The connecting bracket is fixedly connected to the holding frame. The lower end of the movable seat is threadedly connected to the locking screw.

[0010] As a further description of the above technical solution: The air-drying mechanism includes a support plate, a mounting frame, and a fan. The support plate is fixedly connected to the upper right side of the galvanizing tank, the mounting frame is fixedly connected to the right side of the support plate, and the fan is fixedly connected inside the mounting frame.

[0011] This utility model has the following beneficial effects: Compared with existing technologies, this hot-dip galvanizing equipment for screws, by setting up a drying mechanism, can quickly dry and cool the screws in the holding frame after hot-dip galvanizing, which greatly shortens the drying and cooling time and thus effectively improves production efficiency.

[0012] Compared to existing technologies, this hot-dip galvanizing equipment for screws, by incorporating a second motor, a disc, a sliding rod, a movable seat, a slide rail, and a sliding hole, allows the second motor to operate during the screw galvanizing process. This rotation of the disc causes the sliding rod to slide within the sliding hole. Because the sliding rod is located at the edge of the disc and its axis is not aligned with the disc's axis, this eccentric design pushes the movable seat along the slide rail in a reciprocating linear motion during rotation. The movable seat is fixedly connected to the holding frame via a connecting assembly, causing the holding frame to vibrate rhythmically. This vibration ensures sufficient flow of molten zinc in the galvanizing tank, guaranteeing uniform contact between all surfaces of the screw and the molten zinc, effectively avoiding the uneven coating thickness caused by screw accumulation in traditional equipment. Simultaneously, the vibration promotes the escape of air bubbles from the screw surface, preventing coating defects caused by residual air bubbles, thus significantly improving the integrity and adhesion of the galvanized layer. After the galvanizing process is completed, the shaking of the container helps the zinc liquid drip down, allowing excess zinc liquid to flow back into the galvanizing tank and avoiding waste of zinc liquid.

[0015] Reference Figure 1-5This utility model provides a hot-dip galvanizing equipment for screws, including a galvanizing tank 1, a lifting mechanism 2 at the rear end of the galvanizing tank 1, a shaking mechanism 3 at the lower end of the lifting mechanism 2, a connecting component 4 at the lower end of the shaking mechanism 3, and the shaking mechanism 3 being connected to a holding frame 5 via the connecting component 4. The shaking mechanism 3 is used to drive the holding frame 5 to shake. The lifting mechanism 2 is used to drive the holding frame 5 to move up and down. A heating element 7 is installed at the bottom of the inside of the galvanizing tank 1, and a drying mechanism 6 is provided on the upper right side of the galvanizing tank 1. The drying mechanism 6 is used to dry and cool the screws inside the holding frame 5.

[0016] In operation, the screws to be hot-dip galvanized are placed in the holding frame 5, and the heating element 7 is activated to heat the molten zinc in the galvanizing tank 1 to a suitable hot-dip galvanizing temperature. Then, the lifting mechanism 2 slowly lowers the holding frame 5 into the galvanizing tank 1, ensuring the screws are completely submerged in the zinc. During the galvanizing process, the shaking mechanism 3 operates, causing the holding frame 5 to shake rhythmically, ensuring a uniform zinc layer adheres to the screw surface and improving the quality of the hot-dip galvanizing. After galvanizing, the lifting mechanism 2 is activated again to remove the holding frame 5 from the galvanizing tank 1. At this point, the drying mechanism 6 begins operation to dry and cool the screws in the holding frame 5, causing the zinc layer on the screw surface to solidify rapidly, forming a dense protective layer. Once the screws have completely cooled, they can be removed from the holding frame 5, completing the entire hot-dip galvanizing process.

[0017] The lifting mechanism 2 includes a fixed plate 201, a first motor 202, a lead screw 203, a movable frame 204, and a cantilever 205. The fixed plate 201 and the first motor 202 are fixedly connected to the rear end of the galvanizing tank 1. Two fixed plates 201 are provided. The lead screw 203 is rotatably connected inside the fixed plate 201. The movable frame 204 is threaded onto the lead screw 203. The upper end of the movable frame 204 passes through the upper fixed plate 201 and is slidably connected to it. The cantilever 205 is fixedly connected to the upper end of the movable frame 204. The output of the first motor 202... The end is fixedly connected to the lead screw 203. During operation, the first motor 202 is started, and the first motor 202 drives the lead screw 203 to rotate. Since the moving frame 204 is threadedly connected to the lead screw 203 and slidably connected to the fixed plate 201, the rotation of the lead screw 203 will drive the moving frame 204 to move vertically, which in turn drives the cantilever 205 to move vertically. When the cantilever 205 moves down, it is convenient to place the holding frame 5 into the galvanizing tank 1. When the cantilever 205 moves up, it drives the holding frame 5 to move up, which is beneficial for the subsequent drying and cooling of the galvanized screws.

[0018] The swaying mechanism 3 includes a second motor 301, a disc 302, a slide rod 303, a movable seat 304, a slide rail 305, and a sliding hole 306. The second motor 301 is fixedly connected to the upper end of the cantilever 205. The output end of the second motor 301 passes through the cantilever 205 and is rotatably connected to it. The disc 302 is fixedly connected to the output end of the second motor 301. The slide rod 303 is fixedly connected to the lower end of the disc 302. The slide rail 305 is fixedly connected to the lower end of the cantilever 205. The movable seat 304 is slidably connected to the slide rail 305. A sliding hole 306 is formed on the upper surface of the movable seat 304. The slide rod 303 is located inside the sliding hole 306 and is slidably connected to it. The slide rod 303 is located at the edge of the disc 302, and the axis of the slide rod 303 is not on the same straight line as the axis of the disc 302. During operation, during the screw galvanizing process, the second motor 301 operates, driving the disc 302 to rotate, which in turn causes the slide rod 303 to slide inside the sliding hole 306. Because the slide rod 303 is located at the edge of the disc 302 and its axis does not coincide with the axis of the disc 302, this eccentric design causes the slide rod 303 to push the moving seat 304 to reciprocate linearly along the slide rail 305 during rotation. The moving seat 304 is fixedly connected to the holding frame 5 via the connecting component 4, thus causing the holding frame 5 to shake regularly. This shaking action allows the molten zinc in the galvanizing tank 1 to flow fully, ensuring that all surfaces of the screws are evenly contacted with the molten zinc, effectively avoiding the problem of uneven coating thickness caused by screw accumulation in traditional equipment. Simultaneously, the shaking process also promotes the escape of air bubbles from the screw surface, preventing coating defects caused by residual air bubbles, thereby significantly improving the integrity and adhesion of the galvanized layer. After the galvanizing process is completed, the shaking of the container 5 also helps the zinc liquid to drip down, allowing the excess zinc liquid to flow back into the galvanizing tank 1, thus avoiding waste of the zinc liquid.

[0019] The connecting assembly 4 includes a connector 401, a connecting bracket 402, and a locking screw 403. The connector 401 is fixedly connected to the lower end of the movable base 304, and the connecting bracket 402 is inserted into the connector 401. The connecting bracket 402 is fixedly connected to the holding frame 5. The locking screw 403 is threadedly connected to the lower end of the movable base 304. During operation, when installing the holding frame 5, the connecting bracket 402 is first inserted into the connector 401, and then the locking screw 403 is rotated so that the end of the locking screw 403 tightly abuts against the connecting bracket 402, thereby achieving a stable connection between the connecting bracket 402 and the connector 401, and thus reliably fixing the holding frame 5 under the movable base 304. When it is necessary to disassemble the holding frame 5, simply rotate the locking screw 403 in the opposite direction to disengage its end from the connecting bracket 402, and then pull the connecting bracket 402 out of the connector 401 to easily remove the holding frame 5. This connection method is simple to operate.

[0020] The air-drying mechanism 6 includes a support plate 601, a mounting frame 602, and a fan 603. The support plate 601 is fixedly connected to the upper right side of the galvanizing tank 1, and the mounting frame 602 is fixedly connected to the right side of the support plate 601. The fan 603 is fixedly connected inside the mounting frame 602. During operation, when the holding frame 5 rises to the corresponding position of the air-drying mechanism 6 with the lifting mechanism 2, the fan 603 is started. The strong airflow generated by the fan 603 blows directly onto the screws in the holding frame 5, which can ensure that the airflow covers the surface of the screws and quickly removes the heat and residual zinc liquid from the surface of the screws, thereby achieving efficient air drying and cooling.
