Description

Technical Field

[0001] This utility model relates to the field of vehicle body painting technology, and in particular to a multi-functional paint drying chamber. Background Technology

[0002] Automobiles must undergo a painting process during production to give the car body a beautiful appearance and make it more corrosion resistant, thereby increasing the car's commercial and usability value. In addition, painting also serves as a special identification feature. Currently, the car body painting process generally adopts a multi-layer spray painting process.

[0003] Utility model patent CN211660343U discloses an automotive body painting device, comprising two fixed chambers. Each fixed chamber has a vertical plate fixedly connected to its top, and a slide rail fixedly installed on opposite sides of each vertical plate.

A second threaded rod with one end penetrating through and extending into the front installation chamber is fixedly connected to the front of the drive device.

[0004] This utility model patent achieves vehicle body painting through the above design, saving time and labor and eliminating the need for manual painting. By setting up a dryer, an electric push rod can be activated to drive the dryer to dry the vehicle body after the painting is completed. However, this utility model patent can only paint the vehicle body from both sides and dry it from the top, resulting in uneven painting and drying of the vehicle body. Utility Model Content

[0005] The main technical problem to be solved by this utility model is to provide a multi-functional paint drying chamber with a simple overall structure, convenient use and operation, which can quickly and evenly paint and dry the car body.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A multifunctional spray painting and drying chamber includes a base plate, a top plate arranged parallel to the base plate at a certain distance, a first fixed plate and a second fixed plate fixedly connected between the top plate and the base plate, a hot air drying device for outputting hot air to dry the painted surface after spraying, a spray painting device for spraying paint on the four sides of the vehicle body on the second fixed plate, a rotating rod rotatably connected to the base plate via a bearing, a first clamping plate fixedly connected to the upper end of the rotating rod, a driving device for driving the rotating rod to rotate on the base plate, a threaded rod threadedly connected to the top plate, a handwheel fixedly connected to the upper end of the threaded rod, a second clamping plate rotatably connected to the lower end of the threaded rod via a bearing, and a clamping position provided between the first clamping plate and the second clamping plate.

[0008] The following are further optimizations of the above technical solution by this utility model:

[0009] Multiple sets of mounting holes are provided on the side surfaces of the first clamping plate and the second clamping plate that are close to each other. The multiple sets of mounting holes are arranged sequentially at intervals. Each set of mounting holes includes multiple spaced mounting countersunk holes. The inner surface of the mounting countersunk holes is provided with internal threads. Multiple top posts are provided on the side surfaces of the first clamping plate and the second clamping plate that are close to each other. The multiple top posts are fixedly installed in the mounting countersunk holes by means of threaded connection.

[0010] Further optimization: The roof pillars come in various specifications and have different overall lengths, and a rubber pad is installed on the end of the roof pillar that connects to the roof of the vehicle.

[0011] Further optimization: The painting device includes a paint pump, which is fixedly installed on the outer wall of the second fixed plate. The inlet of the paint pump is fixedly connected to a suction pipe, and the outlet of the paint pump is fixedly connected to an outlet pipe. The end of the outlet pipe away from the paint pump passes through the second fixed plate and is fixedly connected to a connecting pipe. Multiple nozzles are provided on the connecting pipe.

[0012] Further optimization: The hot air drying device includes an air duct, which is fixedly connected to a first fixed plate. The end of the air duct near the nozzle passes through the first fixed plate and is fixedly connected to an air outlet. A heating wire and a blower are installed inside the air duct.

[0013] Further optimization: The cross-sectional shape of the air outlet is trapezoidal.

[0014] Further optimization: The top plate, bottom plate, first fixed plate and second fixed plate enclose a drying chamber, and the rear and front sides of the drying chamber are respectively provided with opening and closing doors, which are used to open or close the drying chamber.

[0015] Further optimization: The drive device includes a motor, which is fixedly mounted on the base plate. The output end of the motor is connected to a second gear, and a first gear is fixedly connected to the rotating rod. The first gear meshes with the second gear.

[0016] Further optimization: A masking film is fixedly installed on the four sides of the first clamping plate and the second clamping plate respectively. The other side of the masking film is attached to the vehicle body by an adhesive component. The masking film is used to cover the areas on the vehicle body that need to be covered.

[0017] Further optimization: The top plate and bottom plate are respectively equipped with circulating fans on both sides of the clamping position. The circulating fans work to circulate the air in the drying chamber, which facilitates the drying operation of the car body.

[0018] This utility model, through its rational design, combines a painting device and a hot air drying device. After the car body is painted, it can be directly dried with hot air without having to transfer the car body to a drying chamber, which is highly convenient. During the painting and drying process, the motor drives the first clamping plate to rotate, which in turn drives the car body to rotate, making it easy to spray paint evenly all around the car body and making the car body drying speed more efficient.

[0019] In this invention, the rotation of the threaded rod can drive the second clamping plate to move downward, thereby clamping the car body between the first clamping plate and the second clamping plate through the downward pressure of the second clamping plate. The first clamping plate and the second clamping plate contact the top and bottom surfaces of the car body respectively through the top column, thus adapting to the asymmetrical planar structure of the top and bottom sides of the car body, improving the clamping effect on the car body. Furthermore, the installation position of the top column can be adjusted, making it suitable for clamping operations on different car bodies.

[0020] In this utility model, a masking film is fixedly installed on the four sides of the first clamping plate and the second clamping plate respectively. The masking film is made of plastic film. One side of the masking film is fixedly installed on the first clamping plate, and the other side of the masking film can be pasted to the vehicle body by adhesive components such as single-sided tape and double-sided tape. At this time, the masking film can cover the areas on the vehicle body that need to be covered, avoiding repeated painting or uneven painting.

[0021] In this invention, the hot air output from the air outlet does not blow directly onto the vehicle body, but rather blows into the drying chamber, raising the temperature inside the drying chamber for drying the vehicle body. Circulating fans are respectively installed on both sides of the clamping position on the top and bottom plates. The circulating fans work to circulate the air inside the drying chamber, facilitating the drying operation of the vehicle body.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0028] Example 1: As Figure 1-3 As shown, a multifunctional spray painting and drying chamber includes a base plate 21. A top plate 1 is arranged parallel to the base plate 21 at a certain distance. A first fixing plate 6 and a second fixing plate 18 are fixedly connected between the top plate 1 and the base plate 21. The first fixing plate 6 is equipped with a hot air drying device for outputting hot air to dry the painted surface. The second fixing plate 18 is equipped with a spray painting device for spray painting the four sides of the vehicle body. A rotating rod 8 is rotatably connected to the base plate 21 via a bearing. A first clamping plate 11 is fixedly connected to the upper end of the rotating rod 8. A driving device for driving the rotating rod 8 to rotate is provided on the base plate 21. A threaded rod 19 is threadedly connected to the top plate 1. A handwheel 20 is fixedly connected to the upper end of the threaded rod 19. A second clamping plate 17 is rotatably connected to the bottom end of the threaded rod 19 via a bearing. A clamping position is provided between the first clamping plate 11 and the second clamping plate 17.

[0029] In this embodiment, the first clamping plate 11 is located directly below the second clamping plate 17. The car body to be painted is placed at the clamping position between the first clamping plate 11 and the second clamping plate 17, and the car body is clamped and fixed by the downward movement of the second clamping plate 17.

[0030] In this embodiment, multiple sets of mounting holes are provided on the side surfaces of the first clamping plate 11 and the second clamping plate 17 that are close to each other. The multiple sets of mounting holes are arranged sequentially at intervals. Each set of mounting holes includes multiple spaced mounting countersunk holes 23. The inner surface of the mounting countersunk holes 23 is provided with internal threads.

[0031] Multiple top posts 22 are provided on the side surfaces of the first clamping plate 11 and the second clamping plate 17 that are close to each other. The multiple top posts 22 are fixedly installed in the mounting countersunk holes 23 by means of threaded connection.

[0032] With this design, the car body has an irregular structure, and the top and bottom sides of the car body are not symmetrical planar structures. When it is necessary to clamp the car body, the corresponding top pillars 22 can be selected and fixedly installed on the first clamping plate 11 and the second clamping plate 17. Then, the car body to be clamped is placed on the first clamping plate 11. At this time, the top pillars 22 on the first clamping plate 11 are used to smoothly support the car body.

[0033] Then, the threaded rod 19 is rotated by the handwheel 20. The threaded rod 19 is threadedly connected to the top plate 1. When the threaded rod 19 rotates, it can drive the second clamping plate 17 to move closer to the first clamping plate 11. At this time, the second clamping plate 17 drives the corresponding top column 22 to abut against the top of the vehicle body. The pressure of the second clamping plate 17 is used to press the vehicle body tightly onto the first clamping plate 11. At this time, the cooperation of the first clamping plate 11 and the second clamping plate 17 is used to perform clamping operation on the vehicle body.

[0034] In this embodiment, the first clamping plate 11 and the second clamping plate 17 contact the top and bottom surfaces of the vehicle body through the top post 22, respectively, thereby adapting to the asymmetrical planar structure of the top and bottom sides of the vehicle body and improving the clamping effect on the vehicle body.

[0035] In this embodiment, the top post 22 is a serialized structure with various specifications and different overall lengths. This design allows for the use of various top posts 22 of different lengths to be connected to the vehicle body, enabling the first clamping plate 11 and the second clamping plate 17 to stably clamp and fix the vehicle body.

[0036] In this embodiment, a rubber pad is provided on the end of the top pillar 22 that is in contact with the top of the vehicle body. The rubber pad allows the top pillar 22 to make elastic contact with the vehicle body, thus protecting the vehicle body and improving its performance.

[0037] In this embodiment, both the first clamping plate 11 and the second clamping plate 17 are provided with a plurality of mounting countersunk holes 23. The position of the top post 22 can be adjusted through the plurality of mounting countersunk holes 23, thereby realizing the adjustment of the top contact position, which is suitable for clamping operations on different car bodies.

[0038] The painting device includes a paint pump 14, which is fixedly installed on the outer wall of the second fixed plate 18. The inlet of the paint pump 14 is fixedly connected to a suction pipe 12, and the outlet of the paint pump 14 is fixedly connected to an outlet pipe 15. The end of the outlet pipe 15 away from the paint pump 14 passes through the second fixed plate 18 and is fixedly connected to a connecting pipe 16. Multiple nozzles 13 are provided on the connecting pipe 16.

[0039] The end of the suction tube 12 away from the paint pump 14 is connected to the paint can.

[0040] With this design, when the paint pump 14 is turned on, the paint in the paint can is sprayed out from multiple nozzles 13 after passing through the suction pipe 12, the outlet pipe 15 and the connecting pipe 16, thus achieving the painting of the car body.

[0041] The hot air drying device includes an air duct 5, which is fixedly connected to the first fixed plate 6. One end of the air duct 5 near the nozzle 13 passes through the first fixed plate 6 and is fixedly connected to an air outlet 2.

[0042] The air duct 5 is equipped with a heating wire 3 and a blower 4.

[0043] The cross-sectional shape of the air outlet 2 is trapezoidal, which can guide the hot air and improve the hot air output effect.

[0044] With this design, when the blower 4 and heating wire 3 are turned on, the airflow generated by the blower 4 becomes hot air after passing through the heating wire 3. The hot air is then delivered to the air outlet 2 through the air duct 5 and blown out from the air outlet 2. At this time, the hot air acts on the drying chamber to quickly dry the painted car body.

[0045] In this embodiment, the top plate 1, the bottom plate 21, the first fixing plate 6 and the second fixing plate 18 enclose a drying chamber. The rear and front sides of the drying chamber are respectively provided with opening and closing doors, which are used to open or close the drying chamber.

[0046] In this embodiment, the airflow can be adjusted by changing the rotation speed of the blower 4. The airflow generated by the blower 4 becomes hot air after passing through the heating wire 3, and this hot air is blown into the drying chamber to quickly dry the painted car body. Furthermore, reducing the airflow of the blower 4 slows down the airflow speed. When the airflow passes through the heating wire 3, it allows for sufficient heat exchange between the heating wire 3 and the airflow, improving the heating effect of the airflow. This, in turn, allows the paint chamber to heat up quickly, improving the drying effect. In addition, reducing the flow speed of the hot air can prevent damage to the paint surface and improve the painting effect.

[0047] In this embodiment, the hot air output from the air outlet 2 enters the drying chamber, and the temperature inside the drying chamber rises, which can quickly dry the painted car body and improve the performance.

[0048] The driving device includes a motor 9, which is fixedly mounted on the base plate 21. The output end of the motor 9 is connected to a second gear 10. A first gear 7 is fixedly connected to the rotating rod 8, and the first gear 7 meshes with the second gear 10.

[0049] With this design, when the motor 9 is started, the motor 9 drives the second gear 10 to rotate. The second gear 10 meshes with the first gear 7 to drive the rotating rod 8 to rotate. The rotation of the rotating rod 8 in turn drives the car body mounted on the first clamping plate 11 to rotate. Furthermore, the second clamping plate 17 and the threaded rod 19 are rotatably connected by bearings. At this time, the second clamping plate 17 can drive the clamped car body to rotate stably, thus improving the usage effect.

[0050] In use, this multi-functional paint drying chamber is suitable for painting all four sides of a car body. Painting the roof can be done in the previous or next process. The car body to be painted is placed above the first clamping plate 11, and then the top column 22 on the first clamping plate 11 supports the car body. Then, the handwheel 20 is turned to drive the threaded rod 19 to rotate. The rotation of the threaded rod 19 can drive the second clamping plate 17 to descend. The descent of the second clamping plate 17 causes the top column 22 on the second clamping plate 17 to support the roof of the car body. Thus, the car body is clamped by the cooperation of the second clamping plate 17, the first clamping plate 11, and the top column 22.

[0051] Then, the motor 9 is started to drive the second gear 10 to rotate. The second gear 10 meshes with the first gear 7 to drive the rotating rod 8 to rotate. The rotation of the rotating rod 8 in turn drives the car body mounted on the first clamping plate 11 to rotate. The second clamping plate 17 and the threaded rod 19 are rotatably connected by bearings. At this time, the second clamping plate 17 can drive the clamped car body to rotate stably, improving the use effect.

[0052] Then, the paint pump 14 is turned on, and paint is sprayed out from multiple nozzles 13 to paint the car body. At the same time, the motor 9 is started. The motor 9 drives the rotating rod 8 to rotate through the second gear 10 and the first gear 7. The rotation of the rotating rod 8 in turn drives the car body mounted on the first clamping plate 11 to rotate, so that the nozzles 13 can spray paint on the four sides of the car body to achieve uniform spraying of the paint layer.

[0053] After the painting is completed, the blower 4 and heating wire 3 can be turned on directly. The airflow generated by the blower 4 becomes hot air after passing through the heating wire 3. The hot air is then delivered to the drying chamber through the air outlet 2. The hot air in the drying chamber is used to quickly dry the car body.

[0054] Example 2: Please refer to Figure 4In this embodiment 2, to ensure that the top of the vehicle body is not repeatedly painted during the painting operation, a masking film 24 is fixedly installed on the four sides of the first clamping plate 11 and the second clamping plate 17. The masking film 24 is made of plastic film. One side of the masking film 24 is fixedly installed on the first clamping plate 11, and the other side of the masking film 24 can be pasted to the vehicle body by adhesive components such as single-sided tape and double-sided tape. At this time, the masking film 24 can cover the areas on the vehicle body that need to be covered, avoiding repeated painting or uneven painting.

[0055] In this embodiment, the hot air output from the air outlet 2 will not blow directly onto the vehicle body, but will blow into the drying chamber to raise the temperature inside the drying chamber for drying the vehicle body.

[0056] The top plate 1 and the bottom plate 21 are respectively provided with circulating fans 25 on both sides of the clamping position. The circulating fans 25 are used to circulate the air in the drying chamber to facilitate the drying operation of the car body.

[0057] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
