Description

Technical Field

[0001] This application relates to the field of paint drying equipment technology, and in particular to a paint drying equipment for radiator production. Background Technology

[0002] As is well known, painting and drying are two crucial post-processing steps in radiator manufacturing, directly affecting the product's corrosion resistance and appearance quality. Currently, many manufacturers use separate painting booths and drying ovens, requiring workpieces to be manually handled or transferred to drying equipment via transport vehicles after painting.

[0003] The above production methods have the following significant problems: the transfer of workpieces between processes consumes a lot of time, resulting in a longer production cycle and making continuous production impossible. During the transfer process, uncured paint surfaces are easily damaged by collisions, scratches, or dust, leading to a decrease in product qualification rate. Therefore, there is an urgent need for a device that can integrate painting and drying functions, achieve automated continuous production, and effectively protect the quality of the paint surface.

[0004] Therefore, we propose a paint spraying and drying device for radiator production that integrates spraying and drying. Utility Model Content

[0005] The purpose of this invention is to provide a paint drying device for radiator production, so as to solve the problems mentioned in the background art.

A T-shaped slider is threaded onto the outside of the transmission threaded rod. The guide rod is fixedly installed inside the main body and is parallel to the transmission threaded rod. A T-shaped slider is slidably connected to the outside of the guide rod. A suspension frame is provided between T-shaped slider one and T-shaped slider two, with both ends of the suspension frame fixedly connected to T-shaped slider one and T-shaped slider two respectively, and the suspension frame is provided with several suspension holes; A separating device is movably disposed between the paint spraying chamber and the drying chamber, and is used to open when the suspension frame passes through and to close during paint spraying or drying operations; A painting device, which is installed in a painting chamber, is used to paint the radiators to be produced. A drying device, which is installed in a drying chamber, is used to dry the radiator after it has been painted. The control device is detachably installed at one end of the main body and is electrically connected to the drive motor, the painting device, the separating device and the drying device respectively.

[0007] As a further embodiment of this utility model: the bottom structure of the spray booth is a slope structure that is inclined to one end, and the bottom of the main body is provided with a drain port at the low position of the slope structure, and a collection tank is detachably provided below the drain port.

[0008] As a further improvement of this utility model: a sealing cover is slidably connected to the bottom of the liquid collection tank, and a finger groove is provided on the sealing cover, with anti-slip texture provided in the finger groove.

[0014] As a further improvement of this utility model: the separating device includes a pair of doors that can slide relative to each other, and the two doors together form a channel for the suspension frame and the workpiece to pass through when they are opened.

[0015] Compared with the prior art, the beneficial effects of this utility model are: By integrating the spray painting chamber and drying chamber into the same main unit and configuring an automatic conveyor mechanism, the entire process of radiator production, from spray painting to drying, is automated and continuous.

Detailed Implementation

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] Please see Figures 1-6In this embodiment of the utility model, a paint drying device for radiator production includes: The main body contains a painting chamber 2 and a drying chamber 3 arranged sequentially along the workpiece conveying direction. The drive motor 4 is detachably installed at one end of the main body. The output shaft of the drive motor 4 extends into the main body through a through hole and is concentrically fixedly connected to a transmission threaded rod 5. A T-shaped slider 6 is threaded onto the outside of the transmission threaded rod 5. Guide rod 7 is fixedly installed inside the main body and is parallel to the transmission threaded rod 5. T-shaped slider 8 is slidably connected to the outside of guide rod 7. The suspension frame 9 is located between the T-shaped slider 6 and the T-shaped slider 8. Both ends of the suspension frame 9 are fixedly connected to the T-shaped slider 6 and the T-shaped slider 8 respectively. The suspension frame 9 has several suspension holes. The partition device 10 is movably disposed between the spray booth 2 and the drying chamber 3, and is used to open when the hanging frame 9 passes through and to close during spray painting or drying operations. The painting equipment is installed in the painting chamber 2 and is used to spray paint the radiators to be produced. Drying device 17 is installed in drying chamber 3 and is used to dry the radiator after painting. The control device 11 is detachably installed at one end of the main body and is electrically connected to the drive motor 4, the painting device, the separating device 10 and the drying device 17 respectively.

[0021] This paint spraying and drying device for radiator production first starts by loading the radiator to be painted, hanging it through the hanging holes of the suspension frame 9, and then starting the entire device via the control device 11. Next, the control device 11 instructs the drive motor 4 to rotate, causing the transmission threaded rod 5 to rotate, making T-shaped slider one and T-shaped slider two slide along the transmission threaded rod 5 and guide rod 7 respectively, thereby moving the suspension frame 9 and the radiator to the painting position. Then, the drive motor 4 stops, and the control device 11 starts the paint spraying device to complete the painting operation on the radiator. After the painting is completed, the drive motor 4 restarts, the separating device 10 opens, and the suspension frame 9 carries the radiator into the drying chamber 3, after which the separating device 10 closes. Finally, the control device 11 starts the drying device 17 to dry the radiator.

[0022] exist Figure 1-6 In the middle: the bottom structure of the spray booth 2 is a sloping structure that slopes to one end. The bottom of the main body is located at the low position of the sloping structure and a drain outlet is provided. A collection tank 12 is detachably installed below the drain outlet.

[0023] This paint spraying and drying device for radiator production has the following features: When spraying paint onto radiators, some of the paint sprayed from the nozzle 16 of the spraying device inevitably fails to adhere to the radiator surface, forming excess paint liquid. The sloping structure at the bottom of the spraying chamber 2 can utilize gravity to guide this excess paint liquid to a lower position, allowing it to be smoothly discharged through the drain port at the bottom of the main body. At the same time, the detachable collection tank 12 below the drain port can collect the excess paint liquid discharged from the drain port, preventing excess paint from flowing randomly and polluting the inside of the device or the surrounding environment, and also preventing paint waste.

[0024] exist Figure 1-6 In the middle: A sealing cover 13 is slidably connected to the bottom of the liquid collection tank 12. The sealing cover 13 has a finger groove with anti-slip texture.

[0025] This paint drying device for radiator production features a slidingly connected sealing cover 13 that effectively seals the paint liquid collected inside the collection tank 12. This prevents leakage of paint due to shaking or tilting during cleaning or transport, thus avoiding contamination of the ground or device components. Furthermore, it reduces the diffusion of harmful gases from paint evaporation into the air, improving the working environment and protecting worker health. Secondly, the finger grooves on the sealing cover 13 provide clear points of force for opening and closing, allowing for easy operation without additional tools, significantly improving ease of use. The anti-slip texture within the finger grooves increases friction between the hand and the sealing cover 13, ensuring stable force application even when the worker's hands are covered in paint or oil, preventing slippage and operational errors, further enhancing safety and reliability during use.

[0026] exist Figure 1-6 In the middle: One end of the main body is detachably connected to a protective cover 14, and the drive motor 4 is set inside the protective cover 14. The protective cover 14 is evenly provided with heat dissipation holes.

[0027] This paint drying device for radiator production provides physical protection for the drive motor 4 with a protective cover 14. This effectively prevents external dust, impurities, and paint particles that may splatter during painting from entering the drive motor 4, thus avoiding these foreign objects from affecting the mechanical transmission performance of the drive motor 4 or causing circuit failures, and extending the motor's service life. Secondly, the drive motor 4 generates heat during operation. Excessive heat accumulation can affect the working efficiency of the drive motor 4 or even cause overheating and damage. The evenly distributed heat dissipation holes on the protective cover 14 form a good airflow channel, helping the drive motor 4 to dissipate the heat generated during operation in a timely manner, maintaining the drive motor 4 within a suitable operating temperature range and ensuring stable power output. Furthermore, the protective cover 14 is detachable. When the drive motor 4 needs inspection, maintenance, or replacement, the staff can easily remove the protective cover 14 without complex disassembly of the main structure, greatly improving the convenience of drive motor 4 maintenance operations.

[0028] exist Figure 1-6 The painting device includes a mounting frame 15 fixed in the painting chamber 2 and a plurality of spray nozzles 16 distributed on the mounting frame 15. The spray nozzles 16 are arranged facing the suspension position of the suspension frame 9 and are connected to an external paint supply system.

[0029] This paint spraying and drying device for radiator production provides a stable mounting base for multiple spray nozzles 16 via a mounting frame 15. This ensures the nozzles 16 remain in a fixed position during the spraying process, preventing uneven spraying due to nozzle movement. Simultaneously, the multiple spray nozzles 16 are distributed around the suspension position of the suspension frame 9, allowing for spraying of the radiator suspended at the position from different angles. This effectively covers all surfaces of the radiator, including corners and gaps, significantly improving the uniformity and comprehensiveness of the paint application, ensuring the radiator's appearance quality and corrosion resistance. Furthermore, the nozzles 16 are oriented towards the suspension position, enabling more precise application of paint to the radiator surface, reducing paint diffusion to non-target areas, minimizing paint waste, and reducing contamination of other components inside the spray booth 2. In addition, the nozzles 16 are connected to an external paint supply system, enabling a continuous and stable paint supply without frequent manual refills, preventing interruptions in the spraying operation due to supply disruptions, significantly improving the continuity and efficiency of the spraying operation, and meeting the needs of mass production of radiators.

[0030] exist Figure 1-6 In the middle: the drying device 17 is one of an infrared heater, an electric hot air circulation system, or a gas heater.

[0031] This is a paint drying device for radiator production. All three types of heaters possess high-efficiency heating capabilities, rapidly increasing the temperature within the drying chamber 3 or directly heating the painted radiators. This promotes rapid curing and drying of the paint on the radiator surface, significantly shortening the drying cycle and meeting the continuous operation requirements of mass production of radiators, ensuring production efficiency. Furthermore, each heater has its own advantages, adaptable to different production scenarios and needs: the infrared heater enables directional heating, has high thermal efficiency and a fast heating rate, suitable for scenarios with tight drying time requirements; the electric hot air circulation system ensures uniform temperature distribution within the drying chamber 3, preventing uneven paint drying and cracking due to localized temperature differences in the radiators, thus ensuring drying quality; the gas heater is more economical in scenarios with lower energy costs or convenient gas supply, helping companies control production costs. This multi-select design allows companies to flexibly choose the appropriate heating method based on their production scale, quality requirements, energy supply, and cost budget, improving the device's applicability and cost-effectiveness.

[0032] exist Figure 1-6 In the middle: the drying chamber 3 has a double-layered insulation structure, and the double layer is filled with insulation cotton.

[0033] This paint drying device for radiator production utilizes insulating cotton with excellent heat insulation properties. Filled within the chamber's interlayer, it forms an effective heat barrier between the drying chamber 3 and the external environment, significantly reducing heat loss from the drying device 17 within the drying chamber 3. This prevents temperature instability due to heat loss, ensuring the heat output from the drying device 17 is concentrated on the painted radiator. This maintains the paint on the radiator surface at a suitable curing temperature, reducing uneven drying and decreased adhesion caused by temperature fluctuations, thus improving drying quality. Furthermore, reduced heat loss means the drying device 17 does not require frequent start-stop or continuous high-load operation to replenish lost heat. This reduces energy consumption, helping companies control production energy costs, and minimizes operational wear and tear, extending its lifespan. A stable indoor temperature environment also makes the drying cycle more controllable, preventing prolonged drying time due to insufficient temperature and ensuring the continuity and efficiency of radiator mass production.

[0034] exist Figure 1-6 In the middle: a support column 18 is fixedly welded to the bottom of the main body, and a shock-absorbing pad 19 is fixedly connected to the bottom of the support column 18.

[0035] This paint spraying and drying device for radiator production features a fixed welded support column 18 that elevates the entire device, maintaining a certain distance between the bottom of the main body and the ground. This prevents ground moisture and water from directly contacting the bottom components, thus preventing corrosion and extending the device's lifespan. It also provides ample operating space for the installation and maintenance of the drain outlet and collection tank 12 at the bottom of the main body, facilitating daily cleaning and maintenance. Furthermore, the anti-vibration pad 19 at the bottom of the support column 18 plays a crucial role in buffering and damping vibrations. During operation, components such as the drive motor 4 and the drying device 17 vibrate. The anti-vibration pad 19 effectively absorbs this vibration energy, reducing the impact of vibration on the overall structure of the device and preventing loosening or displacement of components due to long-term vibration, ensuring the accuracy of the paint spraying and drying operations. Simultaneously, the anti-vibration pad 19 reduces noise transmitted to the ground, improving the workshop working environment and minimizing interference with surrounding equipment and personnel. In addition, the anti-vibration pad 19 enhances the friction between the device and the ground, further improving the stability of the device and preventing accidental sliding during operation, ensuring production safety.

[0036] exist Figure 1-6 In the middle: the partition device 10 includes a pair of doors that can slide relative to each other, and when the two doors are opened, they together form a channel for the suspension frame 9 and the workpiece to pass through.

[0037] This paint spraying and drying device for radiator production has several advantages. First, when painting or drying is performed separately, the two sliding doors can close tightly, completely separating the spraying chamber 2 and the drying chamber 3. This prevents unattached paint droplets in the spraying chamber 2 from spreading into the drying chamber 3, contaminating the environment inside the drying chamber 3, or affecting the drying quality of the painted radiators. Simultaneously, it prevents high-temperature air from leaking from the drying chamber 3 into the spraying chamber 2, avoiding interference with the normal adhesion and leveling of the paint during the painting process. This ensures that the working environments of the two processes do not affect each other, guaranteeing their respective operational quality. Second, when the hanging frame 9 moves the radiator to be dried from the spraying chamber 2 to the drying chamber 3, the two doors can slide open relative to each other, forming a channel adapted to the size of the hanging frame 9 and the workpiece. This ensures smooth and unobstructed workpiece transport, without affecting the continuity of the entire production process. Furthermore, the sliding opening method is convenient to operate and can be linked with the device's automatic control system to achieve precise coordination between door opening and hanging frame 9 movement, further improving the degree of automation and operational efficiency.

[0038] In this embodiment, the drive motor 4, drying device 17, and nozzle 16 are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, so we will not go into detail here. The drive motor 4, drying device 17, and nozzle 16 are all equipped with matching control switches. The installation position of the control switches is selected according to actual usage needs to facilitate operation and control by the operator. The technology is already very mature and can be implemented.

[0039] The implementation principle of the paint drying device for radiator production in this application embodiment is as follows: First, the worker suspends the radiator to be painted at the suspension station through the suspension hole on the suspension frame 9. Then, the entire device is started by the control device 11. The control device 11 first sends a command to the drive motor 4. After the drive motor 4 starts running, its output shaft drives the transmission threaded rod 5 to rotate. Since the T-shaped slider 6 screwed on the outside of the transmission threaded rod 5 is fixedly connected to one end of the suspension frame 9, and the other end of the suspension frame 9 is fixedly connected to the T-shaped slider 8 slidably connected to the outside of the guide rod 7, the rotation of the transmission threaded rod 5 will be converted into the T-shaped slider 6 moving along the transmission threaded rod 5. The linear movement of the threaded rod 5, along with the synchronous sliding of the T-shaped slider 8 along the guide rod 7, drives the suspension frame 9 and the suspended radiator to move smoothly along the workpiece conveying direction. When the suspension frame 9 moves the radiator to be painted to the painting position, the control device 11 controls the drive motor 4 to stop running, so that the radiator stays within the painting range of the painting device. At the same time, the painting device is started. In the painting device, the mounting bracket 15 fixed in the painting chamber 2 provides stable support for multiple nozzles 16. The nozzles 16 connected to the external paint supply system spray paint onto the radiator at the suspension position. Multiple nozzles 16 facing the suspension position... The paint is applied evenly to the radiator surface from different angles. During the painting process, excess paint that does not adhere to the radiator surface flows downwards under the guidance of the sloping structure at the bottom of the spray booth 2, and is discharged into the removable collection tank 12 below through the drain port at the bottom of the main body. The sealing cover 13 at the bottom of the collection tank 12 seals the collected paint to prevent leakage and the diffusion of harmful gases. After the painting operation is completed, the control device 11 restarts the drive motor 4 and simultaneously controls the partition device 10 to operate: a pair of relatively sliding doors of the partition device 10 open to form a passage for the hanging bracket 9 and the painted radiator to pass through. The hanging bracket 9 carries the radiator through the passage into the drying chamber 3. Then, the door of the separating device 10 closes, completely separating the spray booth 2 and the drying chamber 3, preventing paint droplets in the spray booth 2 from entering the drying chamber 3, and also preventing heat leakage in the drying chamber 3. After entering the drying chamber 3, the control device 11 starts the drying device 17. The drying device 17 quickly raises the temperature inside the drying chamber 3 or directly heats the radiator, promoting the curing and drying of the paint on the radiator surface. The insulation cotton filled in the double-layer insulation structure of the drying chamber 3 effectively reduces the loss of heat from the room to the outside, maintains a stable drying temperature environment, and ensures drying quality and efficiency.
