Description

Technical Field

[0001] This utility model relates to the field of hot-dip galvanizing technology for steel strips, specifically, to a hot-dip galvanizing apparatus for steel strips. Background Technology

[0002] Hot-dip galvanizing of steel strip is a common anti-corrosion treatment method. By immersing the steel strip in molten zinc, a zinc layer is attached to the surface of the steel strip, thereby providing excellent corrosion resistance.

[0003] According to a public announcement (Announcement No.: CN115417211A), a strip steel coiling device for a hot-dip galvanizing production line includes several conveyor rollers for transporting strip steel, two coiling rods, the coiling rods being vertically arranged with coiling grooves at their tops, a coiling roller being positioned between the two coiling rods, with its two ends passing through the two coiling grooves respectively, several shaping blocks being positioned at the ends of the conveyor rollers in the direction of movement, each shaping block having a shaping groove near its end face near the coiling rod, a sliding rod passing through the side wall of the shaping block, a support block being positioned on the ground, the sliding rod being rotatably connected to the support block, a rotary air pump being positioned on the ground, a coiling platform being positioned on the ground, a cleaning rod being positioned on the inner side wall of the coiling groove, a cleaning layer being fixed to the side wall of the cleaning rod, a cleaning hole being opened on the cleaning rod, and a cleaning fan being positioned on the ground for ventilating the cleaning hole. This application has the effect of improving the quality of strip steel coiling.

[0004] The aforementioned patent achieves the effect of improving the strip steel winding quality through the cooperation of components such as two winding rods and winding rollers, but it cannot better solve the technical problem of the strip steel shifting position when it is transported to the bottom of the air knife equipment. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a hot-dip galvanizing device for strip steel, which solves the technical problem of positional displacement of strip steel when it is transported to the bottom of the air knife equipment in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides a hot-dip galvanizing device for steel strip, comprising: a base plate, a transport device disposed on the top of the base plate, a sliding frame disposed on the top of the base plate, a mobile device disposed on the inner side of the sliding frame, an air knife disposed on the side of the mobile device, a baffle disposed on the top of the air knife, and a limiting device disposed on the top of the base plate. The limiting device includes a fixed plate, the bottom of which is fixedly connected to the top of a base plate. A motor is fixedly connected to the side of the fixed plate, and a threaded rod is fixedly connected to the output shaft of the motor. A threaded sleeve is threaded onto the circumferential surface of the threaded rod, and an extension rod is fixedly connected to the circumferential surface of the threaded sleeve. A long plate is fixedly connected to the side of the extension rod, and a compression spring is fixedly connected to the side of the long plate. A push plate is fixedly connected to one end of the compression spring, and a limiting rod is fixedly connected to the side of the fixed plate. The overall function of this limiting device is to achieve precise control and positioning of the strip steel through motor drive and compression spring buffering, while the limiting rod ensures that the movement does not exceed a predetermined range, thereby ensuring the stability and safety of the equipment.

[0007] For example, in at least one embodiment of the present invention, a hot-dip galvanizing device for strip steel further includes: two threaded sleeves, which are symmetrical about the vertical central axis of the threaded rod. The two symmetrically arranged threaded sleeves enable the entire system to operate more smoothly and evenly, while improving the stability, accuracy, and reliability of the device.

[0008] The circumferential surface of the threaded sleeve is slidably connected to the circumferential surface of the limiting rod, and there is a gap between the bottom of the extension rod and the top of the transport equipment. The sliding connection between the threaded sleeve and the limiting rod provides flexible adjustment space, avoiding friction and wear that may be caused by a fixed connection; while the gap between the extension rod and the transport equipment helps to avoid direct collision, reduce mechanical damage, and ensure the stability and smooth operation of the equipment.

[0009] The two threaded sleeves move horizontally in opposite directions, and multiple extension rods, long plates, compression springs, and push plates are provided. The two threaded sleeves moving horizontally in opposite directions provide symmetrical and precise control, making the movement of the extension rod more stable and distributing the load evenly.

[0010] Multiple extension rods, long plates, compression springs, and push plates correspond to two threaded sleeves, with a sliding connection between the bottom of the push plate and the top of the transport equipment. This sliding connection between the push plate and the transport equipment reduces friction, enhances the system's flexibility, cushioning capacity, and stability, enabling the equipment to operate smoothly under different working conditions and preventing jamming or damage.

[0011] Multiple compression springs are provided, arranged in a linear array along the side of the long plate. The parallel design of multiple compression springs allows the entire system to withstand greater external forces without easily deforming or failing, thus enhancing durability and load-bearing capacity.

[0012] According to another aspect, at least one embodiment of this utility model also provides a hot-dip galvanizing device for strip steel, comprising: a spreading device disposed on the top of the base plate, the spreading device including a support frame, the bottom of the support frame being fixedly mounted on the top of the base plate, a sliding groove formed on the side of the support frame, a sliding block slidably connected to the inner side of the sliding groove, a connecting plate fixedly connected to the side of the sliding block, an adjusting spring fixedly connected to the bottom of the connecting plate, a support plate fixedly connected to one end of the adjusting spring, and a spreading plate fixedly connected to the bottom of the support plate. This provides stable support, ensuring smooth operation of the spreading device. Position adjustment via the sliding block increases the flexibility and adjustability of the device. The adjusting spring controls the pressure, achieving uniform pressure application to adapt to different materials. This ensures uniform processing, improving production efficiency and quality. It also provides self-adaptation and protection, preventing equipment damage and adapting to different operating conditions.

[0013] For example, in at least one embodiment of the present invention, a hot-dip galvanizing device for strip steel further includes two support frames, which are symmetrical about the vertical central axis of the base plate. This symmetrical arrangement of the two support frames makes the device more stable and reliable in terms of load-bearing capacity, operational accuracy, and structural strength. It not only improves the durability of the equipment but also ensures uniformity and accuracy during operation, reducing the occurrence of malfunctions.

[0014] Two sliding grooves and sliding blocks are provided, each corresponding to one of the two support frames. This design enables the support frames to be adjustable and stable, allowing the equipment to operate effectively under different conditions.

[0015] The spreading plate is located directly above the conveyor equipment, with a gap between its bottom and the top of the equipment. This gap design helps improve equipment efficiency and extend its service life by reducing wear, providing space for material flow, controlling pressure uniformity, preventing jamming, and reducing vibration.

[0016] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the coordinated operation of components such as a motor, threaded rod, threaded sleeve, and limiting rod achieves the following: Starting the motor drives the threaded rod to rotate. This rotation causes two threaded sleeves to move horizontally towards each other under the constraint of the limiting rod. The horizontal movement of the two threaded sleeves then causes two extension rods to move horizontally towards each other. This movement of the extension rods in turn causes two long plates to move horizontally towards each other. The horizontal movement of the long plates in turn causes a compression spring to move horizontally towards each other. The compression spring then causes a push plate to move horizontally towards each other, thereby limiting the movement of the strip steel on the transport equipment and preventing transport deviation. This achieves precise control and positioning of the strip steel, while the limiting rod ensures that the movement does not exceed a predetermined range, thus guaranteeing the stability and safety of the equipment.

[0017] In this invention, the support frame, sliding block, connecting plate, and other components work together to achieve the following: When the conveying equipment is running, it drives the strip steel to move horizontally. This horizontal movement of the strip steel passes under the spreading plate, which spreads the zinc coating evenly on the surface of the strip steel. Simultaneously, an adjusting spring automatically adjusts the pressure applied to the strip steel by the spreading plate. This achieves uniform pressure application to accommodate different materials, ensuring uniform processing and improving production efficiency and quality. It also provides self-adaptation and protection, preventing equipment damage and adapting to different operating conditions. Attached Figure Description

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-5 As shown, it illustrates a hot-dip galvanizing device for strip steel in one embodiment of the present invention, comprising: a base plate 1, a transport device 2 disposed on the top of the base plate 1, a sliding frame 3 disposed on the top of the base plate 1, a mobile device 4 disposed on the inner side of the sliding frame 3, an air knife 5 disposed on the side of the mobile device 4, a baffle 6 disposed on the top of the air knife 5, and a limiting device 7 disposed on the top of the base plate 1. The limiting device 7 includes a fixed plate 71, the bottom of which is fixedly connected to the top of the base plate 1. A motor 72 is fixedly connected to the side of the fixed plate 71. A threaded rod 73 is fixedly connected to the output shaft of the motor 72. A threaded sleeve 74 is threadedly connected to the circumferential surface of the threaded rod 73. An extension rod 75 is fixedly connected to the circumferential surface of the threaded sleeve 74. A long plate 76 is fixedly connected to the side of the extension rod 75. A compression spring 77 is fixedly connected to the side of the long plate 76. A push plate 78 is fixedly connected to one end of the compression spring 77. A limiting rod 79 is fixedly connected to the side of the fixed plate 71. The overall function of this limiting device 7 is to achieve precise control and positioning of the strip steel through the drive of the motor 72 and the buffering of the compression spring 77. At the same time, the limiting rod 79 ensures that the movement does not exceed the predetermined range, thereby ensuring the stability and safety of the equipment.

[0028] In some examples, two threaded sleeves 74 are provided, symmetrical about the vertical central axis of the threaded rod 73. The two symmetrically arranged threaded sleeves 74 enable the entire system to operate more smoothly and evenly, while improving the stability, accuracy and reliability of the device.

[0029] The circumferential surface of the threaded sleeve 74 is slidably connected to the circumferential surface of the limiting rod 79, and there is a gap between the bottom of the extension rod 75 and the top of the transport device 2. The sliding connection between the threaded sleeve 74 and the limiting rod 79 provides flexible adjustment space and avoids friction and wear that may be caused by a fixed connection; while the gap between the extension rod 75 and the transport device 2 helps to avoid direct collision, reduce mechanical damage, and ensure the stability and smooth operation of the equipment.

[0030] The two threaded sleeves 74 move horizontally in opposite directions, and multiple extension rods 75, long plates 76, compression springs 77, and push plates 78 are provided. The two threaded sleeves 74 moving horizontally in opposite directions provide symmetrical and precise control, making the movement of the extension rod 75 more stable and distributing the load evenly.

[0031] Multiple extension rods 75, long plates 76, compression springs 77, and push plates 78 correspond to two threaded sleeves 74 respectively. The bottom of the push plate 78 is slidably connected to the top of the transport device 2. The sliding connection between the push plate 78 and the transport device 2 reduces friction, enhances the system's flexibility, buffering capacity, and stability, enabling the equipment to operate smoothly under different working conditions and avoiding jamming or damage.

[0032] Multiple compression springs 77 are provided, arranged in a linear array along the side of the long plate 76. The parallel design of multiple compression springs 77 allows the entire system to withstand greater external forces without easily deforming or failing, thus enhancing durability and load-bearing capacity.

[0033] For example, such as Figures 1-5As shown, the motor 72 is started, and the motor 72 drives the threaded rod 73 to rotate. The rotation of the threaded rod 73 causes the two threaded sleeves 74 to move horizontally towards each other under the restriction of the limiting rod 79. The horizontal movement of the two threaded sleeves 74 towards each other causes the two extension rods 75 to move horizontally towards each other. The horizontal movement of the extension rods 75 towards each other causes the two long plates 76 to move horizontally towards each other. The horizontal movement of the long plates 76 towards each other causes the compression spring 77 to move horizontally towards each other. The horizontal movement of the compression spring 77 towards each other causes the push plate 78 to move horizontally towards each other, thereby limiting the strip steel on the transport equipment 2 and preventing the transport deviation problem.

[0034] like Figures 1-5 As shown, this invention illustrates a hot-dip galvanizing device for strip steel in another embodiment, comprising: a spreading device 8 disposed on the top of a base plate 1; the spreading device 8 includes a support frame 81, the bottom of which is fixedly mounted on the top of the base plate 1; a groove 82 is formed on the side of the support frame 81; a sliding block 83 is slidably connected to the inner side of the groove 82; a connecting plate 84 is fixedly connected to the side of the sliding block 83; an adjusting spring 85 is fixedly connected to the bottom of the connecting plate 84; a support plate 86 is fixedly connected to one end of the adjusting spring 85; and a spreading plate 87 is fixedly connected to the bottom of the support plate 86. This provides stable support, ensuring smooth operation of the spreading device 8. Position adjustment is achieved through the sliding block 83, increasing the flexibility and adjustability of the device. The adjusting spring 85 controls the pressure, achieving uniform pressure application to adapt to different materials. This ensures uniform processing, improving production efficiency and quality. It also provides self-adaptation and protection, preventing equipment damage and adapting to different operating conditions. In some examples, two support frames 81 are provided, symmetrical about the vertical central axis of the base plate 1. This symmetrical design of the two support frames 81 makes the device more stable and reliable in terms of load-bearing capacity, operational accuracy, and structural strength. It not only improves the durability of the equipment but also ensures uniformity and accuracy during operation, reducing the occurrence of malfunctions.

[0035] There are two slides 82 and two sliding blocks 83, each corresponding to one of the two support frames 81. This design enables the support frames 81 to be adjustable and stable, allowing the equipment to work effectively under different conditions.

[0036] The spreading plate 87 is located directly above the conveyor 2, and there is a gap between the bottom of the spreading plate 87 and the top of the conveyor 2. This gap design helps to improve the efficiency of the equipment and extend its service life by reducing wear, providing space for material flow, controlling pressure uniformity, avoiding jamming, and reducing vibration.

[0037] For example, such as Figures 1-5As shown, the operator precisely adjusts the height of the spreading plate 87 using the sliding block 83 to ensure it maintains an appropriate distance from the strip surface, achieving optimal coating uniformity and compaction in subsequent operations. After adjustment, the operator starts the transport equipment 2, allowing it to begin operation and smoothly move the strip along the horizontal track. As the strip moves horizontally, it passes the bottom of the spreading plate 87 located above. At this time, as the strip passes, the spreading plate 87 automatically spreads and smooths the zinc coating on the strip surface evenly, ensuring a smooth coating without bubbles or uneven areas. Simultaneously, the pressure of the spreading plate 87 is automatically adjusted by the regulating spring 85, automatically adjusting the pressure applied by the spreading plate 87 to the strip surface according to the strip speed and coating thickness to maintain optimal working conditions, avoid over-compaction or coating damage, and ensure stable and consistent zinc coating quality.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
