Description

Technical Field

[0001] This application relates to the field of galvanized coating technology for carbon steel wire, and more specifically, to an apparatus for galvanizing carbon steel wire. Background Technology

[0002] Low-carbon steel wire, also known as iron wire, is a metal wire made from low-carbon steel through cold drawing. In addition to iron, its composition may also contain alloying elements such as cobalt, nickel, copper, carbon, and zinc. Cold galvanizing, also known as electro-galvanizing, is a corrosion protection method that deposits a zinc layer on the surface of steel wire through an electrolytic process. Specifically, the degreasing and pickling steel wire is placed as the cathode in a zinc salt solution, forming a circuit with the anode zinc plate. Under the action of an applied current, zinc ions are deposited to form a protective layer. Its corrosion protection mechanism is based on the electrochemical potential difference between zinc and iron.

[0003] Currently, most carbon steel wire galvanizing coating equipment on the market suffers from insufficient automation in the feeding system. It can only achieve the basic function of continuous feeding but cannot automatically control the intermittent feeding rhythm, requiring manual intervention or abandoning the intermittent feeding process. This not only affects production efficiency but also leads to unstable coating quality. Summary of the Invention

[0004] The purpose of this application is to provide a carbon steel wire galvanizing coating device, which can solve the technical problems of the current carbon steel wire galvanizing coating device having a low level of automation in the feeding system, only supporting continuous feeding, unable to achieve automatic intermittent control, requiring manual adjustment or cancellation of intermittent process, which reduces efficiency and affects the stability of coating quality.

[0005] This application provides a carbon steel wire galvanizing coating device, including a workbench, an electrolysis device disposed on the workbench, and two intermittent traction components. The electrolysis device is provided with a groove for accommodating the carbon steel wire to pass through, and the two intermittent traction components are respectively disposed on the feed side and the discharge side of the electrolysis device.

[0006] The intermittent traction assembly includes two transmission belts, two compression traction blocks, and a drive assembly for rotating the transmission belts. The transmission belts are rotatably mounted on the worktable. The carbon steel wire passes between the two transmission belts. The corresponding compression traction block is fixedly mounted on the corresponding transmission belt, and the two compression traction blocks can compress and clamp the carbon steel wire against each other.

[0007] The drive assembly includes a motor, four pulleys, four shafts, two gears, and two idler wheels. The shafts rotate through the worktable via bearings. The corresponding pulleys are fixedly mounted on their respective shafts. Two pulleys on the same side are connected by a corresponding transmission belt. The two gears are fixedly connected to shafts on different sides. The output shaft of the motor is connected to one of the gears. The idler wheels rotate on the worktable via bearings, and two idler wheels are located between two gears. The gears and idler wheels are sequentially meshed.

[0008] A guide sleeve is fixedly installed on the workbench, and a guide groove is opened inside the guide sleeve, through which the carbon steel wire passes.

[0009] The guide sleeve is provided in four parts, which are respectively located on the feed side and discharge side of the two intermittent traction components.

[0010] The compression traction block is made of rubber.

[0011] The workbench is equipped with support legs at its lower end.

[0012] The beneficial effects of this utility model are:

[0013] This utility model provides a carbon steel wire galvanizing coating device. The device achieves fully automatic and precise intermittent feeding through the coordinated operation of two intermittent traction components, eliminating the need for manual intervention and improving production continuity. The intermittent pauses allow for sufficient zinc ion deposition, enhancing coating uniformity. By setting up two intermittent traction components with synchronized start and stop control on both sides, the feeding side intermittent traction component provides pushing force, while the discharging side intermittent traction component applies pulling force. The two components work together to maintain a constant micro-tension state for the carbon steel wire within the electrolysis equipment, improving coating thickness uniformity. Furthermore, the symmetrically arranged intermittent traction components can counteract vibrations during the carbon steel wire's movement, improving coating quality stability.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0030] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] like Figures 1 to 4 As shown, this application provides a carbon steel wire galvanizing coating device, including a workbench 1, an electrolysis device 2 disposed on the workbench 1, and two intermittent traction components 3. The electrolysis device 2 is provided with a groove for accommodating the carbon steel wire 4 to pass through, and the two intermittent traction components 3 are respectively disposed on the feed side and the discharge side of the electrolysis device 2.

[0032] The intermittent traction assembly 3 includes two transmission belts 31, two compression traction blocks 32, and a drive assembly 5 for rotating the transmission belts 31. The transmission belts 31 are rotatably mounted on the workbench 1. The carbon steel wire 4 passes between the two transmission belts 31. The corresponding compression traction blocks 32 are fixedly mounted on the corresponding transmission belts 31, and the two compression traction blocks 32 can compress and clamp the carbon steel wire 4 against each other.

[0033] In use, the carbon steel wire 4 is electroplated with zinc by the electrolysis equipment 2 on the workbench 1. The carbon steel wire 4 passes between two transmission belts 31. When the transmission belts 31 are rotated by the drive assembly 5, the extrusion traction blocks 32 fixed on the transmission belts 31 periodically contact, extrude and clamp the carbon steel wire 4. Intermittent traction is achieved by friction. When the two extrusion traction blocks 32 separate, the carbon steel wire 4 stops moving, forming a cycle of "traction-pause-traction" that matches the zinc plating cycle of the electrolysis equipment 2.

[0034] This device achieves fully automatic and precise intermittent feeding through the coordinated operation of two intermittent traction components 3, eliminating the need for manual intervention and improving production continuity. The intermittent pauses allow for sufficient zinc ion deposition, enhancing coating uniformity. By setting up two intermittent traction components 3 with synchronized start and stop control on both sides, the feeding side intermittent traction component 3 provides pushing force, while the discharging side intermittent traction component 3 applies pulling force. Together, they maintain a constant micro-tension state for the carbon steel wire 4 within the electrolysis equipment 2, improving coating thickness uniformity. Furthermore, the symmetrically arranged intermittent traction components 3 can counteract vibrations during the movement of the carbon steel wire 4, improving coating quality stability.

[0035] like Figures 1 to 4 As shown, in this embodiment, the drive assembly 5 includes a motor 51, four pulleys 52, four rotating shafts 53, two gears 54, and two idler wheels 55. The rotating shafts 53 rotate through the worktable 1 via bearings. The corresponding pulleys 52 are fixedly mounted on the corresponding rotating shafts 53. The two pulleys 52 located on the same side are connected by a corresponding transmission belt 31. The two gears 54 are fixedly connected to the rotating shafts 53 located on different sides. The output shaft of the motor 51 is connected to one of the gears 54. The idler wheels 55 are rotatably mounted on the worktable 1 via bearings, and the two idler wheels 55 are located between the two gears 54. The gears 54 and the idler wheels 55 are meshed and connected in sequence.

[0036] When in use, the motor 51 is turned on to drive one of the gears 54 to rotate. This gear 54 drives the other gear 54 to rotate synchronously in the opposite direction through two idler wheels 55. The shaft 53 rotates with the gear 54, and the pulley 52 rotates with the gear 54, thereby realizing the synchronous reverse rotation of the transmission belts 31 on both sides. The extrusion traction block 32 fixed on the transmission belt 31 periodically contacts, extrudes and clamps the carbon steel wire 4, and intermittent traction is achieved through friction.

[0037] like Figure 1 and 2As shown, in this embodiment, a guide sleeve 11 is fixedly installed on the workbench 1, and a guide groove 12 is opened inside the guide sleeve 11. The carbon steel wire 4 passes through the guide groove 12. The guide sleeve 11 constrains the path of the carbon steel wire 4 through the internal guide groove 12 to eliminate vibration during the traction process. When the carbon steel wire 4 passes through the guide groove 12, the wall of the guide groove 12 restricts the radial displacement of the carbon steel wire 4, ensuring that the carbon steel wire 4 passes through the intermittent traction assembly 3 and the electrolysis equipment 2 in a straight line.

[0038] like Figure 1 and 2 As shown, in this embodiment, four guide sleeves 11 are provided, and the four guide sleeves 11 are respectively located on the feeding side and the discharging side of the two intermittent traction components 3. The four guide sleeves 11 form a complete path constraint of "feeding guidance-traction-discharging guidance". Before the carbon steel wire 4 enters the intermittent traction component 3, it is initially positioned by the feeding side guide sleeve 11, and after passing through the intermittent traction component 3, it is calibrated a second time by the discharging side guide sleeve 11, which effectively suppresses the swinging of the carbon steel wire 4 during traction.

[0039] In this embodiment, the extrusion traction block 32 is made of rubber. The rubber extrusion traction block 32 increases the contact area with the carbon steel wire 4 through elastic deformation. When the transmission belt 31 drives the two extrusion traction blocks 32 to approach each other, the extrusion traction block 32 is compressed and deformed to wrap around the surface of the carbon steel wire 4. The carbon steel wire 4 is clamped by static friction. The high coefficient of friction of rubber improves the traction reliability and avoids slippage that leads to loss of control of feeding. Moreover, the elastic deformation characteristics can prevent hard clamps from causing indentations or scratches on the carbon steel wire 4, thus achieving non-destructive traction.

[0040] like Figure 3 As shown in this embodiment, the lower end of the workbench 1 is provided with a support leg 13; the support leg 13 supports and fixes the workbench 1, improving its stability.

[0041] Working principle: When the carbon steel wire galvanizing coating device provided in this application is in use, the carbon steel wire 4 is electro-galvanized by the electrolysis equipment 2 on the workbench 1. The carbon steel wire 4 passes between two transmission belts 31. The motor 51 is turned on to drive one of the gears 54 to rotate. The gear 54 drives the other gear 54 to rotate synchronously in the opposite direction through two idler wheels 55. The rotating shaft 53 rotates with the gear 54, and the pulley 52 rotates with the gear 54, thereby realizing the synchronous reverse rotation of the two transmission belts 31. The extrusion traction block 32 fixed on the transmission belt 31 periodically contacts, extrudes and clamps the carbon steel wire 4, and intermittent traction is achieved by friction. When the two extrusion traction blocks 32 separate, the carbon steel wire 4 stops moving, forming a "traction-pause-traction" cycle rhythm, which matches the galvanizing cycle of the electrolysis equipment 2.

[0042] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
