Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a drying equipment for a steel structure spraying production line. Background Technology

[0002] In the production and processing of steel structural components, spraying is a crucial step, aimed at enhancing the corrosion resistance, wear resistance, and aesthetics of the components. After spraying, drying is the key step to ensure coating quality. Only through thorough and uniform drying can the coating firmly adhere to the surface of the steel structural component, fulfilling its intended protective and decorative functions. Currently, the drying equipment widely used in steel structural component spraying production lines typically consists of a drying chamber, heating system, air supply system, and control system. The drying chamber, serving as the space for drying the steel structural components, is often designed with dimensions based on the common sizes of steel structural components used in the production line to ensure it can accommodate the workpieces to be dried.

[0003] Most existing drying ovens are fixed to the equipment using welding, bolting, or other fixed connection methods. While bolted connections ensure the structural stability of the drying oven during operation, the disassembly process becomes very cumbersome when the drying oven is damaged and needs repair or replacement. Operators need to use multiple tools and spend a lot of time and effort to remove the damaged drying oven, which not only affects the normal operation efficiency of the production line but also increases production downtime. Therefore, we propose a drying device for a steel structure spraying production line. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for a steel structure spraying production line to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions: A drying device for a steel structure spraying production line includes a frame, a conveyor belt mounted on the frame, a motor mounted at the front end of the frame, the output end of the motor passing through the frame and connected to one end of the conveyor belt, a fixed frame fixedly connected to the surface of the frame above the conveyor belt, a drying chamber mounted on the left side of the fixed frame, an adjustment component mounted on the left side of the fixed frame, the drying chamber being connected to the fixed frame via the adjustment component, and a limit component mounted on the top of the conveyor belt.

[0006] Preferably, the adjustment assembly includes a guide rail fixedly connected to the outer left wall of the fixed frame, a slider slidably connected inside the guide rail, a drying chamber fixedly connected to the rear end surface of the slider, a rack fixedly connected to the front end of the slider, two sets of fixed plates symmetrically fixedly connected to the front end surfaces of the guide rail on both sides of the rack, gears rotatably connected inside the fixed plates, a ratchet fixedly connected to the left end of the gears, the ratchet rotatably connected to the fixed plates, a fixed seat fixedly connected to the left side of the guide rail, a rotating rod rotatably connected inside the fixed seat, a torsion spring wound around the surface of the rotating rod in the fixed seat, a pawl fixedly connected to the left side surface of the rotating rod, and the pawl engaging with the ratchet.

[0007] Preferably, the slider is T-shaped, and the guide rail has a through hole that matches the slider.

[0008] Preferably, the rack is L-shaped, and the right angles within the rack are rounded.

[0009] Preferably, the limiting assembly includes a movable chamber fixedly connected to the top of the fixed frame, a bidirectional lead screw rotatably connected inside the movable chamber, a handwheel fixedly connected to the front end of the bidirectional lead screw, the handwheel being rotatably connected to the movable chamber, two sets of handwheels threaded onto the bidirectional lead screw, a transmission block fixedly connected to the right side of the handwheel, a limiting plate fixedly connected to the bottom of the transmission block, a sliding groove formed in the limiting plate, the sliding groove being slidably connected to the drying chamber, and several sets of rotating grooves formed on one side surface of the two sets of limiting plates, with rollers rotatably connected inside the rotating grooves.

[0010] Preferably, the several sets of rotating grooves are designed with equal spacing, and the outer wall of the roller is provided with anti-slip texture.

[0011] The beneficial effects of this utility model are: 1. This utility model uses a rack and pinion to drive a slider to slide within a guide rail, which in turn drives the drying chamber to slide synchronously. Simultaneously, the rack and pinion drive a gear to rotate within a fixed plate, which in turn drives a ratchet to rotate. The restoring force of a torsion spring then drives a rotating rod to reset and rotate within a fixed seat, causing the rotating rod to engage with the ratchet pawl, thus limiting the sliding of the rack and pinion. This allows operators to adjust the distance between the drying chamber and the conveyor belt, enabling the drying of steel structure workpieces of different sizes. Furthermore, the rack and pinion drive the slider to slide out of the guide rail, facilitating quick disassembly of the drying chamber and enabling maintenance.

[0012] 2. This utility model uses a handwheel to drive a bidirectional lead screw to rotate within the movable chamber. The bidirectional lead screw acts on two sets of transmission blocks, causing the transmission blocks to synchronously move the limiting plates. The limiting plates slide along the grooves on the drying chamber, and the two sets of limiting plates converge on the conveyor belt, bringing the rollers on the two sets of limiting plates into contact with the workpiece surface. Then, a motor drives the conveyor belt to rotate, causing the workpiece to move on the conveyor belt while simultaneously rotating the rollers within the trough. This achieves the purpose of limiting the range on the conveyor belt, preventing the workpiece from shifting and affecting the drying of other workpieces. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-4As shown, a drying device for a steel structure spraying production line includes a frame 1, a conveyor belt 2 mounted on the frame 1, a motor 3 mounted at the front end of the frame 1, the output end of the motor 3 passing through the frame 1 and connected to one end of the conveyor belt 2, a fixed frame 4 fixedly connected to the surface of the frame 1 above the conveyor belt 2, a drying chamber 5 mounted on the left side of the fixed frame 4, an adjustment component 6 mounted on the left side of the fixed frame 4, the drying chamber 5 being connected to the fixed frame 4 via the adjustment component 6, and a limit component 7 mounted on the top of the conveyor belt 2.

[0017] As a technical optimization of this utility model, the adjustment component 6 includes a guide rail 61 fixedly connected to the outer wall of the left side of the fixed frame 4, a slider 62 slidably connected inside the guide rail 61, a drying box 5 fixedly connected to the rear end surface of the slider 62, a rack 63 fixedly connected to the front end of the slider 62, two sets of fixed plates 64 symmetrically fixedly connected to the front end surfaces of the guide rail 61 on both sides of the rack 63, a gear 65 rotatably connected inside the fixed plate 64, a ratchet 66 fixedly connected to the left end of the gear 65, the ratchet 66 rotatably connected to the fixed plate 64, a fixed seat 67 fixedly connected to the left side of the guide rail 61, a rotating rod 68 rotatably connected inside the fixed seat 67, a torsion spring 69 wound around the surface of the rotating rod 68 in the fixed seat 67, a pawl 610 fixedly connected to the left side surface of the rotating rod 68, and the pawl 610 meshing with the ratchet 66.

[0018] In practice, the rack 63 drives the slider 62 to slide within the guide rail 61, causing the slider 62 to simultaneously drive the drying chamber 5 to slide. Simultaneously, the rack 63 drives the gear 65 to rotate within the fixed plate 64, which in turn drives the ratchet 66 to rotate. The restoring force of the torsion spring 69 then drives the rotating rod 68 to reset and rotate within the fixed seat 67, causing the rotating rod 68 to engage the pawl 610 with the ratchet 66. This achieves the purpose of limiting the sliding of the rack 63, facilitating the adjustment of the distance between the drying chamber 5 and the conveyor belt 2 by the operator, thus enabling the drying of steel structure workpieces of different sizes. Simultaneously, the rack 63 drives the slider 62 to slide out of the guide rail 61, achieving the purpose of quick disassembly of the drying chamber 5, thereby facilitating maintenance by the operator.

[0019] As a technical optimization of this utility model, the slider 62 is designed in a T-shape, and the guide rail 61 has a through hole that matches the slider 62.

[0020] In practice, this allows the slider 62 to fit fully against the guide rail 61, thereby improving the stability of the slider 62 sliding up and down within the guide rail 61.

[0021] As a technical optimization of this utility model, the rack 63 is designed in an L-shape, and the right angles inside the rack 63 are designed with rounded corners.

[0022] In practice, it allows staff to easily pull the rack 63, which in turn drives the slider 62 to slide up and down within the guide rail 61, thereby adjusting the distance between the drying chamber 5 and the conveyor belt 2.

[0023] As a technical optimization of this utility model, the limiting component 7 includes a movable chamber 71 fixedly connected to the top of the fixed frame 4. A bidirectional lead screw 72 is rotatably connected inside the movable chamber 71. A handwheel 73 is fixedly connected to the front end of the bidirectional lead screw 72. The handwheel 73 is rotatably connected to the movable chamber 71. Two sets of handwheels 73 are threadedly connected to the bidirectional lead screw 72. A transmission block 74 is fixedly connected to the right side of the handwheel 73. A limiting plate 75 is fixedly connected to the bottom of the transmission block 74. A sliding groove 76 is opened in the limiting plate 75. The sliding groove 76 is slidably connected to the drying box 5. Several sets of rotating grooves 77 are opened on the corresponding side surface of the two sets of limiting plates 75. Rollers 78 are rotatably connected in the rotating grooves 77.

[0024] In practice, the handwheel 73 drives the bidirectional lead screw 72 to rotate within the movable chamber 71, and the bidirectional lead screw 72 acts on two sets of transmission blocks 74, causing the transmission blocks 74 to synchronously drive the limiting plates 75 to move. The limiting plates 75 slide on the drying chamber 5 through the slide groove 76, and the two sets of limiting plates 75 converge on the conveyor belt 2, so that the rollers 78 on the two sets of limiting plates 75 are in contact with the surface of the workpiece. Then, the motor 3 drives the conveyor belt 2 to rotate, so that the workpiece moves on the conveyor belt 2 while driving the rollers 78 to rotate in the rotating groove 77. This achieves the purpose of limiting the range on the conveyor belt 2, preventing the workpiece from shifting when moving on the conveyor belt 2, which would affect the drying of other workpieces.

[0025] As a technical optimization of this utility model, several sets of rotating grooves 77 are designed with equal spacing, and the outer wall of the roller 78 is provided with anti-slip texture.

[0026] In practice, multiple rotating grooves 77 can fit into the workpiece, and the workpiece, driven by the conveyor belt 2, drives the rollers 78 to rotate in the rotating grooves 77, and the multiple rotating grooves 77 can achieve the purpose of positioning the workpiece, preventing the workpiece from shifting on the conveyor belt 2, which would affect the drying effect.

[0027] In use, this invention first drives the slider 62 to slide within the guide rail 61 via the rack 63, causing the slider 62 to simultaneously move the drying chamber 5. Simultaneously, the rack 63 drives the gear 65 to rotate within the fixed plate 64, which in turn drives the ratchet 66 to rotate. The ratchet 66 then drives the pawl 610 to rotate, causing the pawl 610 to rotate within the fixed base 67. The rotating rod 68 simultaneously drives the torsion spring 69 to twist. When the drying chamber 5 slides to the appropriate position... At this time, the restoring force of the torsion spring 69 drives the rotating rod 68 to reset and rotate within the fixed seat 67, and causes the rotating rod 68 to drive the pawl 610 to mesh with the ratchet 66, thereby achieving the purpose of limiting the sliding of the rack 63. This facilitates the adjustment of the distance between the drying chamber 5 and the conveyor belt 2 by the operator, thereby achieving the drying of steel structure workpieces of different sizes. At the same time, the rack 63 drives the slider 62 to slide out from the guide rail 61, thereby achieving the purpose of quick disassembly of the drying chamber 5, which in turn facilitates the operator's maintenance of the drying chamber 5.
