Description

Technical Field

[0001] This utility model relates to the field of spray painting equipment, and in particular to an intelligent fully automatic paint roller spraying machine. Background Technology

[0002] Current roller spraying machines on the market use button operation, manual heating, and manual operation of the paint spray gun; one person can only operate one machine. Moreover, full-time human intervention is required during operation. Due to the high degree of human involvement, each operator has different experience, making it difficult to guarantee product quality, resulting in inconsistent quality and low efficiency.

[0003] During the spraying process, the temperature of the workpiece is measured manually with a temperature gun, and the size of the spray gun is adjusted manually. After spraying, the spray gun is cleaned manually. If the product needs to be painted a different color, it must be mixed manually, which is a very cumbersome operation.

[0004] In addition, traditional spray painting equipment requires manual measurement of the product temperature. When the product reaches the temperature that is suitable for spraying, the spray gun needs to be manually turned on. Moreover, the spray gun can only be used for spraying while stationary and cannot be moved. Its spraying range is small and the product is sprayed unevenly. Utility Model Content

[0015] Beneficial effects

[0016] Compared with existing technologies, the advantages of this intelligent fully automatic paint roller spraying machine are:

[0017] 1. Place the parts to be painted inside the constant temperature oven, close the sealed door using the controller, and start the automatic swing-type spray gun system to paint the parts inside the oven. The oven is heated by a heating device to dry the paint surface, while a blower continuously blows air into the oven, allowing exhaust gases to escape through the exhaust vent. The painting and baking process requires no manual intervention, significantly reducing labor costs, and ensuring high consistency in product quality for each batch.

[0018] 2. In the automatic swing spray gun system, the spray gun swings left and right under the action of the left and right swing motor, and swings up and down under the action of the up and down swing motor, so that the sprayed paint can basically cover the surface of the part and the spraying is more uniform.

[0019] 3. The controller controls the color-changing valve through a solenoid valve, allowing different colors of paint or cleaning fluid to be introduced into the spray gun according to different needs, thereby realizing color-changing spraying.

[0020] 4. The linear reciprocating movement mechanism is used to drive the sealing door to move back and forth in a straight line. When the sealing door moves to be directly opposite the opening of the constant temperature oven, the telescopic mechanism presses the sealing door vertically against the opening of the constant temperature oven to seal it and prevent the paint sprayed from the spray gun from drifting out.

[0021] 5. Place the parts that need to be painted inside the roller to avoid direct contact between the parts and the inner wall of the constant temperature oven, thus ensuring the cleanliness of the constant temperature oven.

[0022] 6. In the heating device, air entering the enclosure from the first air inlet fan is heated by the heater, and then enters the partition cavity of the constant temperature oven through the first air vent to heat the oven, thereby baking the painted parts with the heat from the constant temperature oven. When the infrared temperature sensor detects that the temperature inside the constant temperature oven is too high, the controller starts the second air inlet fan to inject cooler air into the enclosure. Alternatively, the angle of the baffle plate can be adjusted by the baffle motor to reduce the airflow velocity through the heater, thereby lowering the temperature of the constant temperature oven and keeping it within an appropriate range. This method facilitates automatic temperature control of the constant temperature oven to achieve a constant temperature baking effect.

[0023] 7. The second heater can quickly heat the heat-conducting plate, which is beneficial for quickly adjusting the temperature of the constant temperature furnace.

[0036] Example

[0037] The specific embodiments of this utility model are as follows: Figures 1 to 9As shown, an intelligent fully automatic paint roller spraying machine includes a frame 1, on which a constant temperature furnace 11 is mounted, with a first opening on one side of the furnace 11. The frame 1 is equipped with a heating device 51 for heating the furnace 11, and a blower 114 communicating with the inner cavity of the furnace 11. The furnace 11 is connected to an exhaust vent 52 communicating with the outside. The frame 1 is equipped with a linear reciprocating movement mechanism parallel to the plane of the first opening of the furnace 11. The linear reciprocating movement mechanism is connected to a sealing door 2 via a telescopic mechanism 34. An automatic oscillating spray gun system 4 is connected to the sealing door 2, and the automatic oscillating spray gun system 4 includes spray guns 45 facing into the furnace 11. The heating device 51, blower 114, linear reciprocating movement mechanism, telescopic mechanism 34, and automatic oscillating spray gun system 4 are all electrically connected to a controller.

[0038] The frame 1 includes a frame, and a cover plate is provided outside the frame. Some of the cover plates are provided with ventilation holes. The first opening of the constant temperature furnace 11, the linear reciprocating movement mechanism, and the exhaust port 52 are all located outside the frame 1. The bottom of the inner cavity of the frame 1 is connected to the outside. Outside air can enter the frame 1 through the ventilation holes at the bottom of the frame 1 and on the cover plate.

[0039] The controller is located inside the electrical control box 61, which is installed on one side of the frame 1. The electrical control box 61 is equipped with a human-machine interface display screen 62, which is electrically connected to the controller.

[0040] The automatic oscillating spray gun system 4 includes a left-right oscillating motor 41 fixedly connected to the sealing door 2. The output shaft of the left-right oscillating motor 41 is connected to a first fixed base 42. An up-down oscillating motor 43 is connected to the first fixed base 42. The output shaft of the up-down oscillating motor 43 is connected to a second fixed base 44. A spray gun 45 is mounted on the second fixed base 44. The spray gun 45 is connected to a servo motor 46, which is used to start or stop the spray gun 45. The left-right oscillating motor 41, the up-down oscillating motor 43, and the servo motor 46 are all electrically connected to a controller. In this embodiment, except for the output end of the spray gun 45 which passes inward through the clearance hole 21 on the sealing door 2, the rest of the automatic oscillating spray gun system 4 is located outside the sealing door 2.

[0041] When the spray gun is stationary at 45, its spray range is 47. Figure 4 As shown, it is basically conical in shape. In the automatic swing spray gun system 4, the spray gun 45 swings left and right under the action of the left and right swing motor 41, and swings up and down under the action of the up and down swing motor 43, so that the sprayed paint can basically cover the surface of the part and the spraying is more uniform.

[0042] A bracket 22 for holding paint containers 23 is connected to the outside of the sealing door 2. A color-changing valve 8 is provided on the sealing door 2, and the color-changing valve 8 is connected to a solenoid valve, which is electrically connected to a controller. The color-changing valve 8 is connected between the paint containers 23 and the spray gun 45 via a pipeline. In this embodiment, there are three paint containers 23, which can hold two different colors of paint and cleaning fluid respectively. The number of color-changing valves 8 corresponds one-to-one with the number of paint containers 23, also three, and each color-changing valve 8 is connected to a paint container 23. When the spray gun 45 needs to spray one color of paint, the corresponding color-changing valve 8 is opened, and the paint passes from the paint container 23 through the color-changing valve 8 and is sprayed out from the spray gun 45. Before color-changing painting, the original color-changing valve 8 is closed, and the color-changing valve 8 corresponding to the cleaning fluid is opened, allowing the cleaning fluid to enter the spray gun 45 to clean it before being sprayed out. Cleaning the paint prevents the mixing of different colors of paint and prevents paint discoloration problems. Color change painting is usually done for different parts. Before cleaning the spray gun 45, the parts need to be taken out of the constant temperature oven 11.

[0043] The linear reciprocating movement mechanism includes two parallel guide sections 32, which are connected to the frame 1 and located on both sides of the first opening of the constant temperature furnace 11. Each guide section 32 has a slider 33 slidably connected to it, and a lead screw is rotatably connected between the two ends of each guide section 32. The lead screw is linked to a drive motor 31, and the slider 33 is threadedly connected to the lead screw. Two telescopic mechanisms 34 are connected between the edge of the sealing door 2 and the slider 33. The telescopic mechanisms 34 can be pneumatic or hydraulic cylinders. The drive motor 31 is electrically connected to the controller. In this embodiment, both guide sections 32 are arranged longitudinally at an angle. A single drive motor 31 is mounted on one of the guide sections 32. This drive motor 31 is connected to a horizontally arranged synchronous shaft, which is perpendicular to both guide sections 32. The synchronous shaft is linked to the lead screw of both guide sections 32 through two sets of bevel gears, thereby enabling a single drive motor 31 to drive the two sliders 33 to rise and fall simultaneously.

[0044] The linear reciprocating movement mechanism is used to drive the sealing door 2 to move back and forth in a straight line. When the sealing door 2 moves to be directly opposite the first opening of the constant temperature furnace 11, the telescopic mechanism 34 presses the sealing door 2 vertically against the first opening of the constant temperature furnace 11 to seal it and prevent the paint sprayed from the spray gun 45 from drifting out.

[0045] The constant temperature furnace 11 has four supporting rollers 113 on its inner side, and a roller 12 is placed on the supporting rollers 113. A gap is left between the roller 12 and the supporting rollers 113, allowing the roller 12 to rotate coaxially with respect to the constant temperature furnace 11 via the four supporting rollers 113. Both the constant temperature furnace 11 and the roller 12 are cylindrical. The roller 12 has a second opening, which faces the same direction as the first opening of the constant temperature furnace 11. During painting, the parts are placed inside the roller 12, and the paint sprayed from the spray gun 45 falls inside the roller 12. After painting is completed, both the roller 12 and the materials are removed, and the roller 12 can be cleaned.

[0046] In this embodiment, the heating device 51 is located below the constant temperature furnace 11. The heating device 51 includes a cover 511, one end of which is connected to a first air inlet fan 512, and the middle of which is connected to a second air inlet fan 513, which is located inside the frame 1. The other end of the cover 511 is provided with multiple first air vents 516. The wall of the constant temperature furnace 11 is provided with an annular partition cavity 115, which is arranged around the inner cavity of the constant temperature furnace 11. The first air vents 516 of the cover 511 are connected to the partition cavity 115. The outer rear wall of the constant temperature furnace 11 is also provided with multiple second air vents 116 that are connected to the partition cavity 115. The cover 511 is also provided with a heater 514 and a baffle plate 515. The heater 514 is specifically an electric heating rod. The air outlet of the first air intake fan 512, the heater 514, the baffle plate 515, the air outlet of the second air intake fan 513, and the first air vent 516 are arranged sequentially. The baffle plate 515 is rotatably coupled to the cover 511 and connected to a baffle plate motor 517, which drives the baffle plate 515 to rotate relative to the cover 511. The baffle plate motor 517, the first air intake fan 512, and the second air intake fan 513 are all electrically connected to the controller. The baffle plate motor 517 is mounted on the cover 511.

[0047] A second heater 112 is provided inside the partition cavity 115. The second heater 112 is also an electric heating rod and is electrically connected to the controller. A heat-conducting plate 110 is provided at the bottom of the inner cavity of the constant temperature furnace 11, and the second heater 112 is located below the heat-conducting plate 110.

[0048] A third air vent 111 is provided on the wall of the constant temperature furnace 11, and the air outlet of the blower 114 is connected to the third air vent 111 through an air duct 1140. In this embodiment, third air vents 111 are provided on both the left and right sides of the wall of the constant temperature furnace 11. The blower 114 is located inside the frame 1, and it delivers air from the frame 1 into the constant temperature furnace 11. The exhaust vent 52 is located at the top of the constant temperature furnace 11. Under the action of the blower 114, the exhaust gas inside the constant temperature furnace 11 is discharged from the exhaust vent 52, thereby realizing the ventilation of the constant temperature furnace 11.

[0049] The sealed door 2 is equipped with an infrared temperature probe 7 for detecting the temperature inside the constant temperature furnace 11. The infrared temperature probe 7 is electrically connected to the controller.

[0050] The parts to be painted are placed inside the rollers 12 of the constant temperature oven 11. The sealing door 2 is closed via the controller, and the automatic oscillating spray gun system 4 is activated to paint the parts inside the constant temperature oven 11. The constant temperature oven 11 is heated by the heating device 51 to dry the paint surface, while the blower 114 continuously blows air into the constant temperature oven 11, allowing the exhaust gas inside the constant temperature oven 11 to be discharged from the exhaust port 52. The painting and baking process requires no manual intervention, significantly reducing labor costs, and the product quality of each production run is highly consistent.

[0051] In the heating device 51, air entering the enclosure 511 from the first air inlet fan 512 is heated by the heater 514, and then enters the partition cavity 115 of the constant temperature oven 11 from the first air outlet 516 to heat the oven 11. The heat from the oven 11 is then used to bake the painted parts. When the infrared temperature sensor 7 detects that the temperature inside the oven 11 is too high, the controller starts the second air inlet fan 513 to inject cooler air into the enclosure 511. Alternatively, the baffle motor 517 can adjust the angle of the baffle 515 to reduce the airflow velocity through the heater 514, thereby lowering the temperature of the oven 11 and keeping it within a suitable temperature range. This method facilitates automatic temperature control of the oven, achieving a constant-temperature baking effect.

[0052] This equipment allows for the input, saving, and retrieval of material spraying formulas. The system's infrared thermometer automatically measures the temperature, adjusts the required temperature, and automatically opens and adjusts the spray gun size. The sealed door automatically opens after spraying. Compared to existing models, this equipment only requires workers to periodically add the material to be painted into the rollers; spraying and drying are controlled by an intelligent PLC, improving production efficiency. Existing models require experienced manual intervention throughout the spraying process, resulting in poor spraying quality. This equipment uses an infrared thermometer to sense the workpiece temperature, intelligently adjusts the temperature inside the constant-temperature furnace, and intelligently opens and adjusts the spray gun size. When a workpiece needs a different color, a color-changing valve is used for switching. All parameters are automatically controlled by the program, resulting in high-quality sprayed materials. One person can operate 10 machines, reducing manual labor, protecting personnel safety, and offering environmental friendliness, sustainability, and low cost.

[0053] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
