Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and specifically to a paint baking device. Background Technology

[0002] Surface treatment is a crucial step in improving the performance and appearance of metal components. Among these processes, baking paint is widely used in the production and processing of various metal products, such as automotive parts, hardware tools, and appliance housings, because it can form a uniform, wear-resistant, and corrosion-resistant protective layer on the metal surface. However, with the increasing demands for surface quality from downstream industries and the increasingly stringent production efficiency and environmental standards, traditional baking paint equipment has gradually revealed many technical shortcomings and can no longer meet the actual needs of modern metal processing. Traditional metalworking painting equipment often employs an integrated heating furnace structure, using electric heating tubes or gas heating components to heat the entire furnace space, thereby achieving paint curing of metal workpieces. For example, Chinese utility model patent CN214917347U provides a painting device where the workpiece to be painted is hung on a hanging unit, and then the bottom of the workpiece is fixed by a fixing unit. After closing the chamber door, the workpiece is baked via a heating plate. Then, a motor is driven to rotate, causing the rotating shaft, hanging unit, and workpiece to rotate together with the motor, allowing the heating plate to evenly bake the workpiece.

[0003] However, most existing paint baking devices with workpiece flipping functions can only process a single or limited number of workpieces. After each paint baking, the workpiece in the equipment needs to be removed and replaced with a new workpiece, which makes it impossible to achieve continuous paint baking and results in a decrease in processing efficiency. In view of this, a paint baking device is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model proposes a painting device to solve the technical problem mentioned in the background art that most existing painting devices with workpiece flipping function can only process a single or limited number of workpieces. After each painting, the workpiece in the equipment needs to be taken out and replaced with a new workpiece, which makes it impossible to achieve continuous painting and leads to a decrease in processing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paint baking device, comprising: A frame, on which a housing is provided, the housing having a gap for the workpiece to pass through, and a heating device being provided inside the housing; The hooks are provided in multiple sets and connected to the frame, and the frame is provided with a conveying mechanism that drives the multiple sets of hooks to move circumferentially; A drive assembly is disposed on the housing and connected to the hooks to drive the set of hooks to rotate after the corresponding hooks and their attached workpieces enter the housing.

[0006] In a preferred embodiment, the conveying mechanism includes: Mounting plates are arranged in two sets at intervals, and both are fixedly mounted on the frame; Two sets of sprockets are arranged at intervals and can be rotatably disposed between the two sets of mounting plates. A drive motor connected to one set of sprockets is also provided on the mounting plate. A chain is fitted onto two sets of sprockets, and multiple sets of hooks are respectively connected to multiple segments of the chain.

[0007] In a preferred embodiment, a connecting plate is provided on the segment of the chain, and a connecting seat is provided on the hook, the connecting seat being connected to the connecting plate by bolts.

[0008] In a preferred embodiment, the driving component includes: The mounting post is fixedly mounted on the connecting seat, and its end is provided with a rotatable drive wheel; An abutment seat is provided on the housing, and a slidable abutment plate is provided on one side of it. After the workpiece enters the housing, the corresponding drive wheel can abut against the abutment plate. A guide ramp is provided at the end of the abutment plate. An elastic element is disposed between the abutment seat and the abutment plate.

[0009] In a preferred embodiment, a receiving plate is provided at the end of the mounting column, and a snap-fit ​​bracket and a positioning column are provided on the drive wheel. The snap-fit ​​bracket is rotatably snapped onto the receiving plate, and the positioning column passes through the end of the mounting column.

[0010] In a preferred embodiment, the mounting column is provided with a limiting wheel, and the housing is provided with an L-shaped baffle arranged opposite to the abutment plate, so that the limiting wheel can abut against the L-shaped baffle when it moves.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This device, during operation, drives multiple sets of hooks in a circumferential motion via a conveying mechanism, enabling continuous workpiece transport and improving the automation and production efficiency of the baking paint process. The chamber and internal heating device provide the necessary baking environment and temperature for the workpieces, ensuring stable baking conditions. After the workpiece enters the chamber, the drive assembly rotates the hooks, causing the workpiece to rotate synchronously.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0015] Example: like Figure 1As shown, this utility model provides a paint baking device, including a frame 1, a box 14 is provided on the frame 1, the box 14 has a gap for the workpiece to pass through, and a heating device 15 is provided inside the box 14. When baking paint, the workpiece can enter the box 14 through the gap and the paint on the outside of the workpiece is heated by the heating device 15 to achieve the paint baking function.

[0016] like Figures 1 to 3 As shown, in this embodiment, the frame 1 is provided with multiple sets of hooks 13, and the frame 1 is provided with a conveying mechanism that drives the multiple sets of hooks 13 to move in a circumferential direction. The conveying mechanism includes two sets of mounting plates 2 arranged at intervals on the frame 1, and two sets of rotatable sprockets 3 arranged at intervals between the two sets of mounting plates 2. The mounting plate 2 is also provided with a drive motor 20 connected to one of the sprockets 3. A set of chains 4 is sleeved on the two sets of sprockets 3, and the multiple sets of hooks 13 are respectively connected to multiple segments of the chain 4.

[0017] In use, the device controls the rotation of the sprocket 3 via the drive motor 20, which in turn drives the chain 4. Connecting plates 5 are installed on segments of the chain 4, and connecting seats 6 are installed on hooks 13. The connecting seats 6 are bolted to the connecting plates 5. During the movement of the chain 4, the connecting plates 5 drive the connecting seats 6, causing multiple sets of hooks 13 to move circumferentially and sequentially enter the housing 14. Before the hooks 13 enter the housing 14, workpieces to be processed are hung on them. After the hooks 13 are removed from the housing 14 and the workpieces have cooled, they can be removed for continuous painting. Furthermore, the arrangement of the mounting plate 2 supports the chain 4, preventing it from detaching from the sprocket 3.

[0018] like Figure 1 , 3 As shown, in this embodiment, a drive assembly connected to the hooks 13 is provided on the housing 14. The drive assembly drives the hooks 13 to rotate after the corresponding hooks 13 and the workpieces they hang on enter the housing 14. The drive assembly includes a mounting post 7 fixedly mounted on the connecting seat 6. A rotatable drive wheel 10 is provided at the end of the mounting post 7. An abutment seat 16 is provided on the housing 14. A slidable abutment plate 17 is provided on one side of the abutment seat 16. After the workpiece enters the housing 14, the corresponding drive wheel 10 can abut against the abutment plate 17. A guide ramp 18 is provided at the end of the abutment plate 17. An elastic element 19 is provided between the abutment seat 16 and the abutment plate 17.

[0019] After the hook 13 and the workpiece enter the housing 14, the drive wheel 10 can be guided by the arrangement of the guide ramp 18. At the same time, the abutment plate 17 is pushed to compress the elastic element 19, so that the restoring force of the elastic element 19 causes the abutment plate 17 to abut against the drive wheel 10, and increases the friction between the abutment plate 17 and the drive wheel 10, thereby driving the drive wheel 10 to rotate. During the rotation of the drive wheel 10, the hook 13 and the workpiece it hangs on can rotate, so as to heat the workpiece from all directions and improve the uniformity of the paint baking.

[0020] like Figure 3 As shown, in this embodiment, a receiving plate 8 is provided at the end of the mounting post 7, and a snap-fit ​​bracket 11 and a positioning post 12 are provided on the drive wheel 10. The snap-fit ​​bracket 11 is rotatably snapped onto the receiving plate 8, and the positioning post 12 passes through the end of the mounting post 7. The arrangement of the receiving plate 8 allows the drive wheel 10 to rotate at the end of the mounting post 7. In addition, it can be understood that ball bearings can be arranged between the snap-fit ​​bracket 11 and the receiving plate 8 to reduce the friction when the snap-fit ​​bracket 11 rotates and reduce energy consumption. The arrangement of the positioning post 12 can prevent the snap-fit ​​bracket 11 from shifting off from the receiving plate 8.

[0021] like Figure 2 , 3 As shown, in this embodiment, a limiting wheel 9 is provided on the mounting column 7, and an L-shaped baffle 21 is provided on the housing 14 opposite to the abutment plate 17. The limiting wheel 9 can abut against the L-shaped baffle 21 when it moves. After the hook 13 enters the housing 14, it limits the mounting column 7 through the cooperation of the L-shaped baffle 21 and the limiting wheel 9, preventing the mounting column 7 from shifting when the abutment plate 17 pushes the drive wheel 10, thus improving the stability of the device during operation.

[0022] The specific usage and beneficial effects of this utility model are as follows: During operation, this device drives multiple sets of hooks 13 to move circumferentially via a conveying mechanism, enabling continuous workpiece transport and improving the automation and production efficiency of the painting process. The housing 14 and internal heating device 15 provide the necessary painting environment and temperature for the workpiece, ensuring stable painting conditions. After the workpiece enters the housing 14, the drive assembly rotates the hooks 13, causing the workpiece to rotate synchronously. This ensures that all surfaces of the workpiece are evenly heated and treated with paint, effectively preventing uneven painting and inconsistent quality, thus improving the overall painting quality. This device allows for continuous painting of workpieces without requiring replacement after each painting cycle, and it automatically flips the workpieces during the painting process, further enhancing processing efficiency.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
