Description

Technical Field

[0001] This utility model relates to the technical field of spraying equipment for aluminum single-panel production, and in particular to a spraying equipment for aluminum single-panel production. Background Technology

[0002] Aluminum panel production spraying equipment is a specialized piece of equipment used in the aluminum panel manufacturing industry, specifically designed for coating the surface of aluminum panels. It is a key piece of equipment for improving the quality and aesthetics of aluminum panel products. This equipment typically consists of a spraying chamber, a spraying system, a paint supply system, a conveying system, and a control system. The spraying chamber, as the core working space, allows the spraying equipment to apply different coatings such as primer, topcoat, and clear varnish to the pre-treated aluminum panel surface. This imparts excellent corrosion resistance, wear resistance, and decorative properties to the aluminum panels, meeting the appearance and quality requirements of various applications such as building curtain walls and interior decoration. This ensures that aluminum panels exhibit excellent visual effects and durable performance in various architectural decoration projects.

[0003] However, existing aluminum panel spraying processes have many drawbacks. Traditional manual spraying relies on operators holding spray guns. Since paints often contain volatile organic compounds, heavy metals, and other harmful substances, the paint mist and volatile gases generated during spraying are easily inhaled by operators. Long-term exposure can cause significant damage to the respiratory and nervous systems, seriously threatening the health of workers. Furthermore, manual spraying is limited by the operator's skill and physical strength, resulting in low efficiency and difficulty meeting the demands of large-scale production. This not only wastes significant labor costs but also prolongs production cycles and increases production costs for enterprises. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a spraying device for aluminum single-panel production, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a spraying device for aluminum single-panel production, comprising a plurality of linear array support frames, a spray chamber, a drying chamber, a spraying chamber, and a baking chamber. A ring chain conveyor assembly is fixedly connected between the plurality of support frames. The spray chamber, drying chamber, spraying chamber, and baking chamber are arranged sequentially along the conveying direction of the ring chain conveyor assembly. First dust collection frames are fixedly connected to both the left and right sides of the spraying chamber. A connecting pipe is fixedly connected to the top of each first dust collection frame. A filter frame is fixedly installed on the top of the spraying chamber by bolts. The ends of the two connecting pipes furthest from the first dust collection frames are fixedly connected to the filter frame. An exhaust fan is fixedly installed on the top of the filter frame. The exhaust fan is connected to the two connecting pipes through the filter frame. Two symmetrically arranged cover plates are fixedly installed on the top of the filter frame by bolts. Two symmetrically arranged connecting plates are fixedly connected to the bottom surface of each cover plate. A plurality of linear array activated carbon plates are fixedly connected between the two connecting plates, with each activated carbon plate corresponding to a connecting pipe.

[0007] Preferably, in any of the above solutions, a retaining plate is fixedly connected to the bottom surface of each connecting plate, and the connecting plate is engaged with the filter frame through the retaining plate.

[0008] Preferably, in any of the above solutions, two symmetrically arranged guide plates are fixedly connected to the side of each connecting plate away from the activated carbon plate, and a plurality of symmetrically arranged guide grooves are opened on the inner wall of the filter frame, and the guide plates are slidably connected to the filter frame through the guide grooves.

[0009] Preferably, in any of the above embodiments, the output end of the baking chamber is fixedly connected to a frame, and a plurality of linear array fans are embedded in the inner wall of the frame, with each of the fans corresponding to the output end of the baking chamber.

[0010] Preferably, in any of the above embodiments, the outer surface of the exhaust fan is fixedly connected with a plurality of circumferentially arrayed reinforcing ribs, and the bottom ends of the plurality of reinforcing ribs are fixedly connected to the top of the filter frame.

[0011] Preferably, in any of the above schemes, two symmetrically arranged second dust collection frames are fixed to the bottom surface of each first dust collection frame, and both second dust collection frames are connected to the connecting pipe through the first dust collection frame, with the feed inlet of the baking chamber located between the two second dust collection frames.

[0012] Preferably, in any of the above schemes, two symmetrically arranged baffles are fixedly connected to both the left and right sides of the spraying chamber, and the bottom surfaces of several second dust collection frames are respectively attached to the top surfaces of several baffles.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. Compared to the inefficiency caused by manual spraying due to operator skill and physical strength limitations, this aluminum panel production spraying device achieves efficient and continuous operation through the coordination of a ring chain conveyor assembly and various functional chambers. Several support frames firmly support the ring chain conveyor assembly, which sequentially and orderly guides the aluminum panels into the spray chamber for surface cleaning, drying in the drying chamber, spraying in the coating chamber, and curing in the baking chamber. The entire process is automated, requiring minimal manual intervention. Unlike manual spraying, where efficiency is affected by factors such as operator fatigue and variations in technique, this device can stably and quickly complete the aluminum panel spraying process, significantly shortening the production cycle, increasing output per unit time, meeting the efficiency demands of large-scale production, and reducing the company's labor and time costs.

[0015] 2. The spraying device, equipped with components such as the first dust collection frame, connecting pipe, filter frame, and activated carbon plate, effectively solves the problem of paint mist and dust collection and facilitates maintenance. During operation in the spraying chamber, the exhaust fan draws the paint mist and dust generated during spraying into the first dust collection frame through the connecting pipe. Some of the heavier dust settles in the first and second dust collection frames, while air containing fine particles and harmful gases enters the filter frame through the connecting pipe, where it is adsorbed and filtered by the activated carbon plate. The purified air is then discharged, achieving effective collection and treatment of paint mist and dust, protecting the workshop environment and the health of workers. When maintenance or replacement of the activated carbon plate is required, simply open the cover. Because the connecting plate is engaged with the filter frame via a clamping plate, and the guide plate cooperates with the guide groove, the cover plate with the activated carbon plate can be easily pulled out. This convenient operation eliminates the need for complex disassembly, facilitating timely maintenance of the activated carbon plate and ensuring the device continues to perform its paint mist and dust collection and filtration functions efficiently.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0024] like Figures 1 to 6 As shown, a spraying device for aluminum single-panel production includes several linearly arrayed support frames 1, a spray chamber 2, a drying chamber 3, a spraying chamber 4, and a baking chamber 5. A ring chain conveyor assembly 6 is fixedly connected between the support frames 1. The spray chamber 2, drying chamber 3, spraying chamber 4, and baking chamber 5 are arranged sequentially along the conveying direction of the ring chain conveyor assembly 6. First dust collection frames 7 are fixedly connected to both the left and right sides of the spraying chamber 4. A connecting pipe 8 is fixedly connected to the top of each first dust collection frame 7. The top of the spraying chamber 4 is fixed with bolts. The filter is equipped with a filter frame 9. The ends of the two connecting pipes 8 away from the first dust collection frame 7 are fixedly connected to the filter frame 9. An exhaust fan 10 is fixedly installed on the top of the filter frame 9. The exhaust fan 10 is connected to the two connecting pipes 8 through the filter frame 9. Two symmetrically arranged cover plates 11 are fixedly installed on the top of the filter frame 9 by bolts. Two symmetrically arranged connecting plates 12 are fixedly connected to the bottom surface of each cover plate 11. Several linear arrays of activated carbon plates 13 are fixedly connected between the two connecting plates 12. The several activated carbon plates 13 are connected to the corresponding connecting pipes 8.

[0025] As an optional technical solution of this utility model, a retaining plate 14 is fixedly connected to the bottom surface of each connecting plate 12. The connecting plate 12 is engaged with the filter frame 9 through the retaining plate 14. During installation, simply align the retaining plate 14 on the connecting plate 12 with the slot of the filter frame 9 and insert it to quickly fix the connecting plate 12 with the activated carbon plate 13 inside the filter frame 9. No complicated tools are required, and the operation is simple and efficient. When the activated carbon plate 13 needs to be repaired or replaced after a period of use, pull the connecting plate 12 outward, and the retaining plate 14 will disengage from the slot, making it easy to remove the activated carbon plate 13 for processing. This design makes the maintenance of the activated carbon plate 13 easier, effectively ensuring the purification effect of the filter frame 9 on paint mist and dust, and ensuring the continuous and stable operation of the spraying device.

[0026] As an optional technical solution of this utility model, each connecting plate 12 has two symmetrically arranged guide plates 15 fixedly connected to the side away from the activated carbon plate 13. The inner wall of the filter frame 9 has several symmetrically arranged guide grooves 16. The guide plates 15 are slidably connected to the filter frame 9 through the guide grooves 16. When installing the connecting plate 12, the guide plates 15 slide along the guide grooves 16, ensuring that the connecting plate 12 is accurately inserted into the filter frame 9, avoiding installation difficulties or poor sealing due to misalignment. During disassembly, the guide structure also ensures that the connecting plate 12 is smoothly pulled out, preventing the activated carbon plate 13 from colliding with the filter frame 9 and causing damage. Simultaneously, the symmetrically arranged guide plates 15 and guide grooves 16 enhance the stability of the connecting plate 12 within the filter frame 9, ensuring that the activated carbon plate 13 will not shake or shift during the filtration of paint mist and dust, thus guaranteeing the reliability of the filtration effect.

[0027] As an optional technical solution of this utility model, a frame 17 is fixedly connected to the output end of the baking chamber 5. Several linear array fans 18 are embedded in the inner wall of the frame 17, each fan corresponding to the output end of the baking chamber 5. After the aluminum panel completes coating curing in the baking chamber 5, the fans 18 blow air onto the surface of the aluminum panel, accelerating airflow and promoting rapid dissipation of residual heat and rapid evaporation of moisture, thus shortening the cooling time of the aluminum panel. Simultaneously, the evenly distributed fans 18 ensure uniform stress on the surface of the aluminum panel, preventing deformation due to excessively high local temperatures or uneven cooling, ensuring the flatness and quality of the aluminum panel, providing a good foundation for subsequent processing or use, and improving the overall efficiency and product quality of aluminum panel production.

[0028] As an optional technical solution of this utility model, a plurality of circumferentially arrayed reinforcing ribs 19 are fixedly connected to the outer surface of the exhaust fan 10. The bottom ends of the reinforcing ribs 19 are all fixedly connected to the top of the filter frame 9. During the operation of the exhaust fan 10, a certain amount of vibration and force will be generated. The reinforcing ribs 19 can evenly distribute these forces onto the filter frame 9, preventing the exhaust fan 10 from loosening or shifting due to vibration, ensuring that the exhaust fan 10 works continuously and stably, and maintaining the power of the spraying device to extract paint mist and dust. At the same time, the setting of the reinforcing ribs 19 can also improve the structural strength of the exhaust fan 10 itself, reduce the risk of component damage caused by long-term vibration, extend the service life of the exhaust fan 10, reduce equipment maintenance costs, and ensure the normal operation of the spraying device.

[0029] As an optional technical solution of this utility model, each first dust collection frame 7 has two symmetrically arranged second dust collection frames 20 fixed on its bottom surface. Both second dust collection frames 20 are connected to the connecting pipe 8 through the first dust collection frame 7. The feed inlet of the baking chamber 5 is located between the two second dust collection frames 20. During the spraying process, heavier paint mist dust particles settle into the first dust collection frame 7 first under the action of gravity, while smaller dust particles continue to rise under the action of the exhaust fan 10, some of which enter the connecting pipe 8, and the rest fall into the second dust collection frame 20 below. This layered collection method can more comprehensively capture paint mist dust of different particle sizes, avoiding dust accumulation and diffusion in the spraying chamber 4. At the same time, the layout of the feed inlet of the baking chamber 5 located between the two second dust collection frames 20 makes the aluminum single panel less susceptible to dust contamination during transportation, ensuring the spraying quality of the aluminum single panel, reducing the dust content in the workshop, and improving the working environment.

[0030] As an optional technical solution of this utility model, two symmetrically arranged baffle plates 21 are fixedly connected to both the left and right sides of the spray booth 4. The bottom surfaces of several second dust collection frames 20 are respectively attached to the top surfaces of several baffle plates 21. The baffle plates 21 support the second dust collection frames 20 to prevent dust from spilling due to shaking during use, thus ensuring the effectiveness of dust collection by the second dust collection frames 20. At the same time, the baffle plates 21 can play a certain role in sealing the spray booth 4, reducing the escape of paint mist dust from the sides of the spray booth 4. Together with the first dust collection frame 7 and the second dust collection frame 20, they form a more complete dust collection and protection system, effectively reducing the dust concentration in the workshop, protecting the health of the staff, and reducing dust pollution to other equipment and the environment in the workshop, maintaining the cleanliness of the workshop and the normal operation of the equipment.

[0031] A spraying device for aluminum single-panel production operates on the following principle:

[0032] 1): Several support frames 1 firmly support the ring chain conveyor assembly 6. Under its drive, the aluminum single panel can enter the spray chamber 2 for surface cleaning, drying chamber 3 for drying, spraying chamber 4 for spraying, and baking chamber 5 for curing in an orderly manner. The whole process is automated.

[0033] 2): When working in the spray booth 4, the exhaust fan 10 draws the paint mist and dust generated during spraying into the first dust collection frame 7 through the connecting pipe 8. Some of the heavier dust settles in the first dust collection frame 7 and the second dust collection frame 20, while the air containing fine particles and harmful gases enters the filter frame 9 through the connecting pipe 8 and is adsorbed and filtered by the activated carbon plate 13. The purified air is then discharged.

[0034] In summary, this aluminum panel production spraying device achieves efficient and continuous operation through the coordination of the ring chain conveyor assembly 6 and various functional chambers. Several support frames 1 stably support the ring chain conveyor assembly 6, allowing the aluminum panels to sequentially and orderly enter the spray chamber 2 for surface cleaning, the drying chamber 3 for drying, the spraying chamber 4 for spraying, and the baking chamber 5 for curing. The entire process is automated, requiring minimal manual intervention. Unlike manual spraying, where efficiency is affected by factors such as worker fatigue and differences in operating techniques, this device can stably and quickly complete the spraying process of aluminum panels, significantly shortening the production cycle, increasing output per unit time, meeting the efficiency demands of large-scale production, and reducing the company's labor and time costs. The first dust collection frame 7, connecting pipe 8, filter frame 9, and activated carbon plate 13 components of the spraying device effectively solve the problem of paint mist and dust collection and facilitate maintenance. When the spray booth 4 is in operation, the exhaust fan 10 draws the paint mist and dust generated during spraying into the first dust collection frame 7 through the connecting pipe 8. Some of the heavier dust settles in the first dust collection frame 7 and the second dust collection frame 20, while the air containing fine particles and harmful gases enters the filter frame 9 through the connecting pipe 8, where it is adsorbed and filtered by the activated carbon plate 13. The purified air is then discharged, achieving effective collection and treatment of paint mist and dust, protecting the workshop environment and the health of the staff. When the activated carbon plate 13 needs to be inspected or replaced, simply open the cover plate 11. Since the connecting plate 12 is engaged with the filter frame 9 through the clamping plate 14, and the guide plate 15 cooperates with the guide groove 16, the cover plate 11 with the activated carbon plate 13 can be easily pulled out. The operation is convenient and does not require a complicated disassembly process, facilitating timely maintenance of the activated carbon plate 13 and ensuring that the device continues to perform its paint mist and dust collection and filtration function efficiently.
