Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a spraying device for a water-based paint coating production line for automotive parts. Background Technology

[0002] In the production process of water-based paint coating for automotive parts, cleaning and descaling the parts before coating is a critical step. It is necessary to ensure that the parts are dry, clean, rust-free, and oil-free to guarantee the quality of subsequent water-based paint coating. Although the current mainstream spraying equipment can achieve basic cleaning functions, it faces the challenge of adapting to the diverse structures of automotive parts. For example, when dealing with complex structural parts with grooves, holes, or irregularly shaped parts, existing equipment often uses a fixed-angle suspension method for spraying. Since the angle of the parts cannot be adjusted, the water flow from the nozzle is difficult to cover the dead corner areas of the parts, resulting in the incomplete removal of dirt in these areas, affecting the adhesion of subsequent water-based paint, and may even cause quality problems such as coating peeling and rusting.

[0003] For example, a spraying device for electrophoretic coating with patent publication number "CN222568070U" includes a housing with drive motors symmetrically arranged at the upper end of the housing and protective shells symmetrically installed inside. The output end of the drive motor is connected to a screw, the lower end of which extends into the interior of the protective shell. Guide rods are symmetrically arranged inside the protective shell, and threaded blocks are fitted around the screws. The guide rods pass through the threaded blocks, and a suspension mechanism is fixed at one end of the threaded blocks. The drive motor drives the screw to rotate, causing the threaded blocks to move up and down along the guide rods, thereby adjusting the height of the suspension mechanism and the spacing between the hooks. This allows for the adaptation of suspension to different specifications and sizes of components, enabling the components to obtain a more reasonable spraying position within the device. This expands the water flow coverage to a certain extent and alleviates some of the problems of incomplete cleaning.

[0004] However, the aforementioned patents do not cover the function of adjusting the angle of automotive components. Due to the significant structural differences between different automotive components, adjusting only the height and spacing cannot change the posture of the component itself. For example, when cleaning an engine block with deep holes, a fixed-angle suspension will cause the axis of the hole to be inconsistent with the direction of water flow, making it difficult for the water to penetrate into the hole. When cleaning a suspension arm with a bent structure, the inner side of the bend is always in the water flow blind zone. This limitation of the fixed angle makes the cleaning effect of the dead corner area of ​​the component still poor, and the problem of dirt residue is not fundamentally solved. This will still pose a hidden danger to the quality of subsequent water-based paint coating. At the same time, repeated cleaning may increase production costs and reduce production efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a spraying device for a water-based paint coating production line for automotive parts. It solves the problem of adjusting the angle of automotive parts, which is not covered in the aforementioned patents. Due to the significant structural differences between different automotive parts, adjusting only the height and spacing cannot change the posture of the parts themselves. For example, when cleaning an engine block with deep holes, a fixed-angle suspension will cause the axis of the hole to be inconsistent with the direction of water flow, making it difficult for the water to penetrate into the hole. When cleaning a suspension arm with a bent structure, the inner side of the bend is always in the water flow blind zone. This limitation of the fixed angle makes the cleaning effect of the dead corner area of ​​the parts still unsatisfactory, and the problem of dirt residue is not fundamentally solved. This will still pose a hidden danger to the quality of subsequent water-based paint coating. At the same time, repeated cleaning may increase production costs and reduce production efficiency.

[0006] To achieve the above objectives, this utility model provides a spraying device for a water-based paint coating production line for automotive parts, including a housing. A circulation mechanism for recycling water resources to save resources is provided on one side of the housing. A spraying mechanism for spraying and cleaning automotive parts is provided inside the housing. The spraying mechanism includes a gear and a hook. The gear is fixedly connected inside the housing, and the hook is fixedly connected to one end of the gear.

[0007] A water tank is fixedly connected to one side of the box body, a filter plate is fixedly connected to the inner wall surface of the box body, and a No. 1 water pump is fixedly connected to one side of the water tank.

[0008] The filter plate has a slidably connected box on its upper surface, a water supply pipe is fixedly connected to one side of the box, and the other end of the water supply pipe is fixedly connected to one side of the No. 1 water pump.

[0009] The top of the inner wall of the box is fixedly connected to an installation box, the gear is fixedly connected to the bottom of the inner wall of the installation box, and the hook is rotatably connected to the lower surface of the installation box.

[0010] The bottom of the inner wall of the box is slidably connected to a rack, which meshes with the gear. A first electric push rod is fixedly connected to one side of the box, and the rack is fixedly connected to one end of the first electric push rod.

[0011] A second water pump is fixedly connected to the upper surface of the water tank, and a flexible hose is fixedly connected to the upper surface of the second water pump. The flexible hose passes through one side of the tank and is slidably connected to one side of the tank.

[0012] The inner wall of the box is fixedly connected to a second electric push rod. One end of the second electric push rod is fixedly connected to a guide plate. The other end of the hose is fixedly connected to one side of the guide plate. A nozzle is fixedly connected to the other side of the guide plate.

[0013] This utility model discloses a spraying device for a water-based paint coating production line for automotive parts. The core structure of the spraying mechanism, consisting of gears, hooks, a rack, and a primary electric push rod, is installed inside the housing. The primary electric push rod drives the rack to slide along the bottom of the inner wall of the housing. Because the rack meshes with the gear, the sliding of the rack drives the gear to rotate within the mounting box. The hook is fixed to one end of the gear, thus allowing for angle adjustment of the automotive parts suspended by the hook. This structure can flexibly adjust the posture according to the structural characteristics of the parts, ensuring that the dead-angle areas of the parts are precisely aligned with the water flow from the spray nozzle. Simultaneously, a circulation mechanism on one side of the housing filters the spray wastewater through a filter plate. A primary water pump, in conjunction with a water delivery pipe, transports the filtered wastewater back to the water tank, achieving water resource recycling and saving production resources. The overall device not only solves the problem of incomplete cleaning caused by the difficulty in adjusting the part angle in existing technologies, but also considers resource conservation, ensuring the quality and production efficiency of subsequent water-based paint coating.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figures 1-5 A spraying device for a water-based paint coating production line for automotive parts includes a housing 1. A circulation mechanism 2 for recycling water resources to conserve resources is located on one side of the housing 1. Inside the housing 1 is a spraying mechanism 3 for spraying and cleaning automotive parts. The spraying mechanism 3 includes a gear 302 and a hook 305. The gear 302 is fixedly connected inside the housing 1, and the hook 305 is fixedly connected to one end of the gear 302. The housing 1 serves as the main frame of the entire spraying device, providing installation and working space for the circulation mechanism 2 and the spraying mechanism 3. The circulation mechanism 2, based on its installation position on one side of the housing 1, recovers, filters, and reuses wastewater generated during the spraying process, achieving water resource circulation. The gear 302 in the spraying mechanism 3, fixed inside the housing 1, provides an installation base for the hook 305. The hook 305 is used to suspend the automotive parts to be cleaned. The gear 302 can drive the hook 305 to adjust its angle through transmission, coordinating with the spraying action to achieve comprehensive cleaning of the parts.

[0023] Furthermore, a water tank 201 is fixedly connected to one side of the tank body 1, and a filter plate 202 is fixedly connected to the inner wall surface of the tank body 1. A water pump 205 is fixedly connected to one side of the water tank 201. The water tank 201 serves as the core of water resource storage, storing both the initial clean water used for spraying and the recycled wastewater after subsequent filtration, forming a centralized water resource management space. The filter plate 202 is horizontally fixed to the inner wall of the tank body 1. When the wastewater generated by spraying and cleaning falls from above, the filter plate 202 can intercept solid impurities such as metal fragments and paint residue in the wastewater, preventing impurities from flowing in with the water. The water enters the subsequent pipeline; the No. 1 water pump 205 is connected to the water tank 201 through the pipeline. After starting, it can generate negative pressure suction, which provides power for the wastewater to flow back to the water tank 201 and for the clean water to be transported to the spray structure, realizing the circulation of water resources within the device. The water tank 201 reduces the frequency of clean water replenishment and lowers water costs; the filtration function of the filter plate 202 can prevent impurities from clogging the pipes or damaging the water pump components, extending the overall service life of the equipment; the No. 1 water pump 205 provides key power support for water circulation and is the basis for realizing the reuse of water resources, effectively reducing water waste.

[0024] Furthermore, a placement box 203 is slidably connected to the upper surface of the filter plate 202, and a water supply pipe 204 is fixedly connected to one side of the housing 1. The other end of the water supply pipe 204 is fixedly connected to the side of the No. 1 water pump 205. The placement box 203 is set against the upper surface of the filter plate 202 and is adapted to the sliding groove of the filter plate 202. The impurities intercepted by the filter plate 202 will naturally settle or slide into the placement box 203. The staff can pull the placement box 203 out from the side of the housing 1 by sliding it horizontally to complete the impurity cleaning. One end of the water supply pipe 204 is connected to the wastewater collection area at the bottom of the housing 1, and the other end is connected to the No. 1 water pump. The inlet of 205 is fixed. When the No. 1 water pump 205 is started, the wastewater filtered by the filter plate 202 at the bottom of the tank 1 will be stably pumped to the water tank 201 through the water delivery pipe 204 to form a wastewater recycling channel. The sliding placement box 203 can clean impurities without disassembling the filter plate 202, simplifying maintenance operations and saving maintenance time. The water delivery pipe 204 serves as a dedicated wastewater return channel to ensure a stable water flow path and prevent wastewater from leaking or stagnating inside the tank 1. At the same time, it works with the No. 1 water pump 205 to greatly improve the wastewater recycling efficiency and further improve the water resource recycling rate.

[0025] Furthermore, an installation box 301 is fixedly connected to the top of the inner wall of the housing 1, and a gear 302 is fixedly connected to the bottom of the inner wall of the installation box 301. A hook 305 is rotatably connected to the lower surface of the installation box 301. The installation box 301 effectively protects the gear 302, ensuring its transmission stability and service life, and avoiding interference from water flow to the transmission structure. The direct connection between the hook 305 and the gear 302 allows the rotational movement of the gear 302 to be directly converted into the angle adjustment of the component, providing a structural basis for covering the dead corners of the component cleaning and improving the comprehensiveness of cleaning.

[0026] Furthermore, a rack 303 is slidably connected to the bottom of the inner wall of the housing 1. The rack 303 meshes with the gear 302. A first electric push rod 304 is fixedly connected to one side of the housing 1. The rack 303 is fixedly connected to one end of the first electric push rod 304. The telescopic end of the first electric push rod 304 is fixed to one end of the rack 303. When the first electric push rod 304 extends or retracts, it can push the rack 303 to slide. The sliding of the rack 303 will drive the meshing gear 302 to rotate around its own axis. In turn, the gear 302 will drive the hook 305 and the suspended car parts to adjust their angles, realizing the controllable adjustment of the parts' posture. The meshing transmission between the gear 302 and the rack 303 has the characteristics of high transmission accuracy and stable operation. It can realize the control of the parts' angles and ensure that the dead corner areas of the parts can be aligned with the spray water flow. The first electric push rod 304 provides automatic power, eliminating the need for manual adjustment, reducing the intensity of operation. At the same time, the extension and retraction of the electric push rod can be controlled to adapt to the angle requirements of different structural parts, improving the versatility of the device.

[0027] Furthermore, a second water pump 306 is fixedly connected to the upper surface of the water tank 201. A hose 307 is fixedly connected to the upper surface of the second water pump 306. The hose 307 passes through one side of the tank body 1 and is slidably connected to one side of the tank body 1. The inlet of the second water pump 306 is connected to the inside of the water tank 201. After starting, it can draw out and pressurize the water in the water tank 201 to form a spray of water with sufficient impact force. One end of the hose 307 is fixed to the outlet of the second water pump 306, and the other end extends through the strip hole on the side of the tank body 1 into the inside of the tank body 1. The flexible hose 307 is flexible, and the strip-shaped holes on the side of the housing 1 provide it with sliding space. When the guide plate 309 moves, it can drive the hose 307 to slide synchronously without affecting the continuous delivery of water. The second water pump 306 provides high-pressure water flow for spraying, ensuring that the water flow can effectively remove dirt and oil stains from the surface of the components and guarantee the cleaning effect. The flexibility and sliding characteristics of the hose 307 are adapted to the position adjustment of the subsequent nozzle 310, avoiding the rigid pipeline from limiting the movement range of the nozzle 310 and improving the device's adaptability to components of different sizes.

[0028] Furthermore, a second electric push rod 308 is fixedly connected to one side of the inner wall of the housing 1. One end of the second electric push rod 308 is fixedly connected to a guide plate 309, and the other end of the hose 307 is fixedly connected to one side of the guide plate 309. A nozzle 310 is fixedly connected to the other side of the guide plate 309. The second electric push rod 308 is fixed to the inner wall of the housing 1, and its telescopic end is fixed to one side of the guide plate 309. After starting, it can push the guide plate 309 to move laterally back and forth. The guide plate 309 has a diversion channel inside. After the high-pressure water flow delivered by the hose 307 enters the guide plate 309, it is evenly distributed to each nozzle 310 through the diversion channel. The nozzles 310 are evenly distributed on the other side of the guide plate 309 and can spray water to spray and clean the components. The distance between the nozzles and the components is adjusted as the guide plate 309 moves.

[0029] Complete working process: When using this device, first, according to the structure of the automotive parts to be cleaned, suspend the parts on the hook 305. Start the first electric push rod 304, which pushes the rack 303 to slide. The rack 303 meshes with the gear 302, driving the gear 302 to rotate within the mounting box 301. This causes the hook 305 and the parts to rotate synchronously, adjusting the parts to the optimal spray angle. Then, start the second water pump 306. Water in the water tank 201 is pressurized by the second water pump 306 and delivered through the hose 307 to the guide plate 309. The water is then distributed to each nozzle 310 through the flow distribution channel within the guide plate 309. The nozzles 310 spray water to clean the parts. If it is necessary to adjust the distance between the nozzles 310 and the parts, start the second electric push rod 308. The second electric push rod 308 pushes the guide plate 309 to move, causing the nozzles 310 to adjust synchronously, ensuring the water flows at the optimal distance to the surface of the parts. Wastewater from the spraying process falls onto filter plate 202, which intercepts impurities. These impurities fall into collection box 203, and the filtered wastewater flows to the bottom of tank 1. Pump 205 is activated, and the wastewater at the bottom of tank 1 is transported back to water tank 201 via water pipe 204, achieving water resource recycling. After cleaning, all pumps and electric push rods are turned off, and the components can be removed. Collection box 203 is periodically removed to clean impurities, ensuring the filtration effect of filter plate 202.
