Description

Technical Field

[0001] This utility model relates to the field of rapid drying technology for metal spraying, and in particular to a rapid drying device for spraying protective layers on hardware parts. Background Technology

[0002] Rapid drying devices for metal parts after spraying were developed to meet the needs of improving production efficiency and ensuring coating quality. Their function is to significantly shorten the drying time of the protective paint on the metal parts, avoid defects during the drying process, and thus improve the product qualification rate. With the expansion of the metal industry, traditional spraying and natural drying methods can no longer meet the requirements of high-efficiency production. The development of electronic control technology and advanced ventilation systems has provided technical support for rapid drying devices, enabling precise control of drying conditions such as temperature and wind speed, thereby meeting the rapid drying needs of metal parts after spraying.

[0003] One of the existing rust prevention processes for metal parts is to spray paint on their surface. In the existing technology, metal parts mostly rely on natural air drying after painting, which results in a long paint drying process and low processing efficiency.

[0004] Existing patent (CN216857281U) discloses a rapid drying device for metal parts spray painting, relating to the field of rapid drying technology for metal parts spray painting. It includes a base, a back plate fixedly welded to the upper surface of the base, side plates welded to the side of the back plate, a cylinder fixedly installed on one side of the upper surface of the base, and a drive shaft rotatably connected to the side of the back plate via a bearing. A common arc plate is fixedly welded to one end of the drive shaft, and the inner cavity of the common arc plate is fixedly connected to one end of a plastic tube. The other end of the plastic tube is welded to a receiving box. This invention features an air inlet pipe and a paint inlet pipe on one side of the receiving box. The air inlet pipe is connected to an external air supply system, and the paint inlet pipe is connected to an external paint supply system. By controlling the switching mechanism to connect the air inlet pipe to the common arc plate, the drying air from the air inlet pipe can accelerate the drying speed of the paint on the surface of the metal parts, greatly reducing the paint drying process consumption of the metal parts.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, most existing rapid drying devices for spraying use a clamping method to spray the parts, which can easily lead to incomplete spraying. Furthermore, after spraying and drying are completed, the machine needs to be stopped and the parts removed, which is cumbersome and inefficient. In addition, spraying and drying are carried out in the same location, which can cause air pollution and harm the health of workers.

[0006] Therefore, a rapid drying device for spraying protective coatings on hardware parts is proposed. Utility Model Content

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A rapid drying device for spraying protective coating on hardware parts includes a workbench 1, a control panel 2 bolted to the top of the workbench 1, an air filter assembly 3 provided on the top of the workbench 1, and a circulation assembly 4 provided on the top of the workbench 1.

[0029] The circulation component 4 includes a support plate 401. The bottom of the support plate 401 is bolted to the top of the workbench 1. A rotating shaft 402 is rotatably connected to the top of the front side of the support plate 401. A turntable 403 is bolted to the front side of the rotating shaft 402. Three rotating rods 404 are arranged in a ring inside the turntable 403. The front side of the rotating rods 404 extends to the outside of the turntable 403 and is bolted to a placement platform 405. Two connecting rods 406 are bolted to the rear side of the bottom of the placement platform 405. A gravity block 407 is bolted between the bottoms of two adjacent connecting rods 406.

[0030] In this embodiment: the workbench 1 is set as the main body and functional platform of the device. The control panel 2 enables the linkage of various components on the workbench 1 to meet work needs. The air filter component 3 effectively reduces air pollution during operation, protecting the health of workers and the environment. The circulation component 4 enables simultaneous spraying, drying, and part removal, and also facilitates part hanging, achieving continuous operation without stopping the machine. With the support plate 401 fixed on the workbench 1, the rotating shaft 402 has stable rotation conditions. When the power causes the rotating shaft 402 to rotate, the rotating shaft 402 drives the bolted turntable 403 to rotate. The turntable 403 drives the rotation rod 404 to move, and the placement platform 405, which is bolted to the rotation rod 404, can move synchronously with the rotation rod 404. The placement platform 405 is connected to the bottom by a connecting rod 406, and the bottom of the connecting rod 406 is connected to a gravity block 407. Therefore, under the action of gravity, the rotation rod 404 and the turntable 403 achieve a relative rotation relationship, so that the placement platform 405 maintains a horizontal posture while rotating and moving with the turntable 403. Since the turntable 403 is circular, the three placement platforms 405 will continuously cycle from the part picking area, the spraying area, and the drying area in sequence, thereby realizing the cycle of spraying, drying, and part picking.

[0031] Specifically, such as Figure 1 , Figure 3 As shown, the air filter assembly 3 includes a first air intake box 301, the bottom of which is bolted to the top of the workbench 1, and a first air intake pipe 302 is fixedly connected to the front side of the first air intake box 301.

[0032] Specifically, such as Figure 3 As shown, the rear side of the first suction pipe 302 is fixedly connected to the second suction pipe 303, and the other end of the second suction pipe 303 is fixedly connected to the second suction box 304.

[0033] Specifically, such as Figure 3 As shown, the bottom of the first suction pipe 302 is fixedly connected to the suction box 305, the air filter element 306 is installed inside the suction box 305, the bottom of the suction box 305 is bolted to the suction machine 307, and the bottom of the suction machine 307 is bolted to the exhaust box 308.

[0034] In this embodiment: by activating the suction machine 307, the suction machine 307 generates negative pressure on the suction box 305, causing negative pressure to be generated in the suction pipe that is fixedly connected to the suction box 305. The first suction pipe 302 and the second suction pipe 303 are fixedly connected, so that both have negative pressure, thereby realizing the suction function of the first suction box 301 and the second suction box 304, collecting the odor generated when the device is working, and the sucked-in odor gas is filtered through the air filter element 306 set inside the suction box 305, and the filtered air is then discharged through the exhaust box 308.

[0035] Specifically, such as Figure 2 As shown, a first conductive slip ring connection assembly 5 is sleeved on the surface of the rotating rod 404.

[0036] Specifically, such as Figure 4 As shown, a power motor 6 is bolted to the top of the rear side of the support plate 401, and the rear side of the rotating shaft 402 extends to the rear side of the support plate 401 and is bolted to the output shaft of the power motor 6. A second conductive slip ring connecting assembly 7 is sleeved on the surface of the rotating shaft 402.

[0037] In this embodiment: when the power motor 6 is powered on, it rotates, and drives the rotating rod 404 to rotate through the output shaft, which in turn drives the turntable 403 to rotate. Due to the rotational relationship between the support plate 401 and the turntable 403, the power supply connected through the support plate 401 cannot be connected in a fixed manner. Therefore, the second conductive slip ring connection component 7 is needed to realize the transmission of power from the support plate 401 to the turntable 403. The setting of the first conductive slip ring connection component 5 can realize the transmission of power from the turntable 403 to the placement platform 405.

[0038] Specifically, such as Figure 2 As shown, a low-speed motor 8 is bolted to the top of the placement platform 405, and the output shaft of the low-speed motor 8 extends to the bottom of the placement platform 405 and is bolted with a hook 9.

[0039] Specifically, such as Figure 5 As shown, a baffle plate 10 is bolted to the left side of the top of the workbench 1, and a support strip 11 is bolted to the top of the left side of the baffle plate 10. The top of the support strip 11 is bolted to the second air intake box 304. A first support column 12 and a second support column 13 are bolted to the top of the workbench 1. A spraying plate 14 is bolted to the rear side of the first support column 12, and a drying air outlet plate 15 is bolted to the top of the rear side of the second support column 13. A paint inlet pipe 16 and an air inlet pipe 17 are bolted to the top of the front side of the first support column 12 and the second support column 13, respectively.

[0040] In this embodiment: After connecting the paint supply system and the air supply system by the paint inlet pipe 16 and the air inlet pipe 17 respectively bolted to the top of the front side of the first pillar 12 and the second pillar 13, the low-speed motor 8 is bolted to the placement platform 405. The hook 9 can rotate synchronously by connecting to the low-speed motor 8. After the hardware parts to be sprayed are hung on the hook 9, the placement platform 405 is moved horizontally to the spraying area behind the spraying plate 14 bolted to the rear side of the first pillar 12 or to the drying area behind the drying air outlet plate 15 bolted to the top of the rear side of the second pillar 13. The low-speed motor 8 drives the hook 9 to rotate, so that the spraying or drying work is more comprehensive and the spraying and drying quality is improved. In order to improve the effect of the air filter component 3 and prevent the rapid diffusion of odors during the spraying process, a baffle plate 10 is bolted to the left side of the top of the workbench 1.

[0041] Working principle: Before the rapid drying device for spraying the protective layer on hardware parts is put into operation, the paint supply system and the air supply system are connected through the paint inlet pipe 16 and the air inlet pipe 17. After that, the hardware parts that need to be sprayed with the protective layer are hung in the pick-up area. The power motor 6 starts and drives the rotating shaft 402 connected to the support plate 401 to rotate. The rotating shaft 402 drives the bolted turntable 403 to rotate. The turntable 403 drives the rotating rod 404 to move. The rotating rod 404 is bolted to the placement platform 405. The placement platform 405 is fixedly connected to the gravity block 407 through the connecting rod 406. Under the action of the gravity block 407, the rotating rod 404 moves. 04 will rotate relative to the turntable 403, while the rotating rod 404 and its bolted placement platform 405 will move to different areas while maintaining a horizontal posture. When it reaches the picking area, the bolted relationship between the low-speed motor 8 and the placement platform 405 will synchronize the position. The hook 9 bolted to the output shaft end of the low-speed motor 8 can pick up or hang parts. When the hung hardware moves to the spraying area, the hook 9 in the drying area will move to the picking area to pick up and place parts, while the hardware originally in the spraying area will move to the drying area, thus forming a cycle. The power supply on the support plate 401 is turned on. The second conductive slip ring connecting assembly 7 allows power to be transmitted from the support plate 401 to the turntable 403. The first conductive slip ring connecting assembly 5 allows power from the turntable 403 to the low-speed motor 8, causing the low-speed motor 8 to rotate and drive the hardware on the hook 9 to rotate, achieving 360-degree spraying. Following this principle, the hardware moves to the drying area and undergoes the same process. During operation, odors may escape from the spraying area; the enclosure effectively reduces this odor. By starting the suction machine 307, negative pressure is created in the suction box 305, causing the suction box 305 to... The fixedly connected suction pipe generates negative pressure, and the first suction pipe 302 and the second suction pipe 303 are fixedly connected, so that both have negative pressure, thereby realizing the suction function of the first suction box 301 and the second suction box 304. The odor gas generated when the device is working is collected, and the sucked odor gas is filtered through the air filter element 306 set inside the suction box 305. The filtered air is then discharged through the exhaust box 308. According to different working needs, the control panel 2 can adjust the working parameters of the drive motor, the low speed motor 8 and the suction machine 307 to achieve different effects.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
