Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, specifically a multi-station rotary passivation treatment mechanism for zinc-plated parts. Background Technology

[0002] Galvanized parts are components made by forming a zinc layer on the surface of metals such as steel through processes such as hot-dip galvanizing and electro-galvanizing. The zinc layer can not only effectively isolate the metal from contact with air, moisture, acids and alkalis and other corrosive media due to its dense structure, but also protect the base metal by preferentially being corroded when the coating is damaged through the principle of sacrificial anode protection. This treatment significantly improves the corrosion resistance and wear resistance of the metal, while giving it a good appearance and texture. It is widely used in fields such as construction, transportation, power, and machinery manufacturing, such as scaffolding for construction, automotive parts, and power transmission towers. It is an important protective means to enhance the service life and performance of metal materials in modern industrial production.

[0003] In the existing technology, in the construction industry, passivation treatment equipment is used to treat galvanized parts such as steel structural components, scaffolding, and guardrails to maintain surface integrity and extend service life under long-term exposure to wind, sun, and rain. However, during use, the passivation treatment equipment is usually a single station and cannot process multiple galvanized parts at the same time. Furthermore, after passivation, cleaning is required, which usually requires manual transfer, reducing processing efficiency and increasing the risk of workpiece damage.

[0004] Therefore, a multi-station rotary passivation treatment mechanism for galvanized parts is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-station rotary passivation treatment mechanism for galvanized parts, which solves the technical problems that passivation treatment devices are usually single-station and cannot process multiple galvanized parts at the same time. Furthermore, after passivation, cleaning is required, which usually requires manual transfer, reducing processing efficiency and increasing the risk of workpiece damage. This invention achieves the purpose of rotary switching and multi-station processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station rotary passivation treatment mechanism for galvanized parts, comprising a working disc, with legs evenly and uniformly fixedly connected to the bottom circumference of the working disc, a water collection bucket at the bottom of the working disc, a controller fixedly installed on the outer wall of the working disc, a rotation switching component at the top of the working disc, a multi-station processing component at the top of the working disc, and a through hole at the top of the working disc.

[0007] Preferably, the rotation switching assembly specifically includes: an infrared emitter, which is circumferentially and equidistantly fixed on the top of the working plate; a motor, which is fixedly installed on the bottom of the inner wall of the working plate; and a threaded rod, which is fixedly installed on the telescopic end of the motor.

[0008] Preferably, the outer wall of the threaded rod is threadedly connected to a threaded plate, a telescopic rod is fixedly installed at the bottom of the threaded plate, the bottom of the telescopic rod is fixedly installed to the bottom of the inner wall of the working disc, and a bracket is fixedly installed at the top of the threaded plate.

[0009] Preferably, a nail rod is rotatably connected to the top of the bracket, a gear sleeve is fixedly fitted on the outer wall of the nail rod, a reduction motor is fixedly installed on the top of the bracket, a gear is fixedly installed on the output end of the reduction motor, and the surface of the gear meshes with the surface of the gear sleeve.

[0010] Preferably, a boom is fixedly and uniformly connected to the outer circumference of the nail rod. An infrared receiver is fixedly installed at the bottom of the boom, and a hanging rod is fixedly installed at equal intervals at the bottom of the boom. A hole placement box is fixedly installed between the inner sides of the hanging rod. The rotating switching component drives the threaded rod through the motor to lift the threaded plate. The geared motor drives the gear and gear sleeve to mesh, causing the nail rod to drive the boom to rotate. The hole placement box at the bottom of the boom can simultaneously carry multiple galvanized parts. The infrared transmitter and receiver are used for positioning and precise switching to different workstations, realizing continuous operation of multiple processes such as feeding, passivation, cleaning, and drying. This avoids the waiting time of traditional single-workstation equipment and greatly improves processing efficiency. The infrared transmitter and receiver accurately position the workstation, and the motor and geared motor automatically drive the rotation and lifting, reducing manual intervention and operational errors. The controller can be preset with programs to realize full-process automated control, thereby achieving the effect of rotation switching.

[0011] Preferably, the multi-station processing component specifically includes: a collection box, which is circumferentially and evenly distributed on the top of the working tray; a passivation box, which is distributed on the top of the working tray; a cleaning box, which is distributed on the top of the working tray; a drying box, which is fixedly installed on the top of the working tray; a sliding sleeve, which is equidistantly and fixedly installed on both sides of the passivation box and both sides of the cleaning box; and a locking block, which is slidably connected to the inner wall of the sliding sleeve.

[0012] Preferably, the bottom of the card block is fixedly connected to the top of the working disc, the inner wall of the cleaning box has grooves on both sides, the inner wall of the groove is slidably connected to a bent rod, the inner side of the bent rod is fixedly installed with a card frame, the outer wall of the card frame is fitted with the inner wall of the cleaning box, and a filter screen is fixedly installed between the inner walls of the card frame.

[0013] Preferably, the interior of the drying chamber is connected to the interior of the through hole. A connecting frame is installed on one side of the drying chamber. A fan is fixedly installed between the inner walls of the connecting frame. Electric heating rods are fixedly installed at equal intervals between the inner walls of the connecting frame. A heating wire is sleeved on the outer wall of the electric heating rod. In the multi-station processing assembly, the collection box, passivation box, cleaning box, and drying chamber are circumferentially distributed. When the perforated box rotates with the boom, each process can be completed sequentially, forming an assembly line operation. The filter screen in the cleaning box can filter impurities. The bent rod and the clamping frame are easy to disassemble and clean, ensuring the cleanliness of the cleaning solution. The drying chamber forms a hot air circulation through the fan and electric heating rods. Combined with the through hole design, it accelerates the evaporation of moisture, realizes the rapid drying of galvanized parts, and avoids rust. The design of the sliding sleeve and the clamping block makes the passivation box, cleaning box and other components detachable, thereby achieving the effect of multi-station processing.

[0014] This utility model provides a multi-station rotary passivation treatment mechanism for galvanized parts. It has the following beneficial effects:

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0025] The existing passivation treatment devices are typically single-station, unable to process multiple galvanized parts simultaneously, and require cleaning after passivation, usually necessitating manual transfer, which reduces processing efficiency and increases the risk of workpiece damage. Therefore, this utility model provides a preferred embodiment of a multi-station rotary passivation treatment mechanism for galvanized parts, for example... Figure 1-5 As shown: A multi-station rotary passivation treatment mechanism for galvanized parts includes a working disc 1, with support legs 2 evenly and equidistantly fixed to the bottom circumference of the working disc 1, a water collection bucket 3 at the bottom of the working disc 1, a controller 4 fixedly installed on the outer wall of the working disc 1, a rotation switching component 5 at the top of the working disc 1, a multi-station processing component 6 at the top of the working disc 1, and a through hole at the top of the working disc 1.

[0026] The rotary switching assembly 5 specifically includes: an infrared emitter 511, which is circumferentially and equidistantly fixed on the top of the working plate 1; a motor 512, which is fixedly installed on the bottom of the inner wall of the working plate 1; and a threaded rod 513, which is fixedly installed on the telescopic end of the motor 512.

[0027] The outer wall of the threaded rod 513 is threadedly connected to a threaded plate 514. A telescopic rod 515 is fixedly installed at the bottom of the threaded plate 514.

A rod 5114 is fixedly installed at equal intervals at the bottom of the boom 5112. A hole placement box 5115 is fixedly installed between the inner sides of the rods 5114.

[0030] In this example, the galvanized parts can be processed in multiple stations by setting up the rotary switching component 5. The galvanized parts are placed in the first perforation box 5115. The motor 512 is started to drive the threaded rod 513 to rotate, causing the threaded plate 514, bracket 516, and nail rod 517 to descend for passivation. Then, they are raised. The reduction motor 519 is started to drive the gear 5111 to rotate, which in turn drives the gear sleeve 518 and nail rod 517 to rotate, causing the boom 5112, boom 5114, and perforation box 5115 to rotate. The infrared transmitter 511 and infrared receiver 5113 are calibrated and aligned, and then cleaning is performed, thereby achieving the rotary switching function. Example

[0031] Based on Embodiment 1, a preferred embodiment of the multi-station rotary passivation treatment mechanism for galvanized parts provided by this utility model is as follows: Figure 1-5 As shown: The multi-station processing component 6 specifically includes: a collection box 611, which is evenly and circumferentially arranged on the top of the working plate 1; a passivation box 612, which is arranged on the top of the working plate 1; a cleaning box 613, which is arranged on the top of the working plate 1; a drying box 619, which is fixedly installed on the top of the working plate 1; a sliding sleeve 614, which is fixedly installed at equal intervals on both sides of the passivation box 612 and both sides of the cleaning box 613; and a locking block 615, which is slidably connected to the inner wall of the sliding sleeve 614.

[0032] The bottom of the card block 615 is fixedly connected to the top of the working plate 1. The inner wall of the cleaning box 613 has grooves on both sides. The inner wall of the groove is slidably connected to the bent rod 616. The inner side of the bent rod 616 is fixedly installed with a card frame 617. The outer wall of the card frame 617 fits against the inner wall of the cleaning box 613. The inner wall of the card frame 617 is fixedly installed with a filter screen 618.

[0033] The interior of the drying oven 619 is connected to the interior of the through hole. A connecting frame 6111 is installed on one side of the drying oven 619. A fan 6112 is fixedly installed between the inner walls of the connecting frame 6111. Electric heating rods 6113 are fixedly installed at equal intervals between the inner walls of the connecting frame 6111. Heating wires are sleeved on the outer wall of the electric heating rods 6113.

[0034] In this example, the galvanized parts can be processed in multiple stations by setting up the multi-station processing component 6. The passivating agent in the passivation box 612 can passivate the galvanized parts. The passivated galvanized parts are cleaned by the cleaning box 613. The filter screen 618 intercepts impurities. The collection box 611 collects the spilled liquid. The fan 6112 is started to work, and the heating wire heats the electric heating rod 6113. The fan 6112 blows hot air onto the galvanized parts for drying, thereby achieving the function of multi-station processing.

[0035] Working principle: First, when multi-station processing of galvanized parts is required, the galvanized parts are placed in the first perforation box 5115. Then, the controller 4 starts the motor 512 to drive the threaded rod 513 to rotate, causing the threaded plate 514, bracket 516, and nail rod 517 to descend for passivation. The perforation box 5115 then enters the passivation box 612 for passivation. Next, the motor 512 starts to drive the threaded rod 513 to rotate, raising the perforation box 5115. The galvanized parts are then dried. Finally, the reduction motor 519 starts to drive the gear 5111 to rotate. The gear sleeve 518 and nail rod 517 are rotated, causing the boom 5112, boom 5114, and drain hole placement box 5115 to rotate. The infrared transmitter 511 and infrared receiver 5113 are aligned and calibrated. Then, the galvanized parts are placed into the second drain hole placement box 5115 for passivation treatment. Then, the motor 512 is started by the controller 4 to rotate the threaded rod 513, causing the threaded plate 514, bracket 516, and nail rod 517 to descend for cleaning. The first drain hole placement box 5115 is placed into the cleaning box 613 for cleaning, and the filter screen 618 removes impurities. The interception and collection box 611 collects the spilled liquid. Then, motor 512 lifts the leak placement box 5115 for drying. Next, the reduction motor 519 is activated, and the infrared transmitter 511 and infrared receiver 5113 are aligned. The galvanized part is then placed into the third leak placement box 5115. Motor 512 then lowers the leak placement box 5115, allowing the first leak placement box 5115 to enter the drying chamber 619. The third leak placement box 5115 undergoes passivation. Fan 6112 is then activated to supply power to the heating wire. The electric heating rod 6113 is heated, and the fan 6112 blows hot air onto the galvanized part for drying. Excess water falls into the water collection tank 3. The heating temperature of the electric heating rod 6113 can be set by the controller 4. Then, multi-station rotary processing is performed. The sliding sleeve 614 and the clamping block 615 can be detached from the passivation box 612 and the cleaning box 613. The lifting rod 616 can remove the clamping frame 617. The filter screen 618 collects impurities in the cleaning box 613, reducing the frequency of water replacement in the cleaning box 613, thereby achieving the function of multi-station processing.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
