Description

Technical Field

[0001] This utility model relates to the field of edge banding technology, specifically a conveying and steering device for edge banding of environmentally friendly water-based paint sprayed boards. Background Technology

[0002] In the modern panel processing industry, edge banding is a crucial step in enhancing product added value and market competitiveness. Compared to traditional solvent-based coatings, environmentally friendly water-based paints, with their VOC emissions reduced by more than 80%, along with advantages such as fast drying, strong adhesion, and high transparency, are driving innovation in edge banding technology.

[0003] However, traditional sheet metal spraying and edge banding equipment suffers from significant technical bottlenecks in the steering and transport processes. Existing equipment generally lacks automatic steering capabilities, relying on manual or mechanical steering devices, which is not only inefficient but also makes it difficult to guarantee the uniformity and integrity of the spraying and edge banding. Furthermore, during batch edge banding operations, the unstable transport of stacked sheets can easily cause them to shake, leading to displacement or even falling off, severely impacting spraying efficiency.

[0004] Chinese utility model patent CN221069923U discloses a sheet metal conveying and steering device, including a belt conveyor, a sheet metal steering mechanism, and a roller conveyor. The steering mechanism is driven by a downward-pressing cylinder to achieve sheet metal steering. While this patent enables automatic steering and conveying of sheet metal, its reliance on a fixed design of belts and rollers results in insufficient transmission stability.

[0005] To address the aforementioned issues, it is necessary to design a conveying and steering device capable of automatically turning and stably transporting the sheet material, thereby providing reliable technical support for the water-based paint spraying and sealing process.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0025] Please see Figure 1-4 This utility model provides a conveying and steering device for edge sealing of sheet metal sprayed with environmentally friendly water-based paint. It includes a conveying frame 1, with a conveying support roller 2 rotatably mounted on the inner side of the conveying frame 1 via bearings to support the conveying sheet metal. A transition plate 5 is provided on the inner side of the conveying frame 1 and between adjacent conveying support rollers 2 to reduce conveying sway. A support base 10 is installed at the bottom of the conveying frame 1, with screw holes at the bottom. The support base 10 is bolted to the interior of the spraying chamber. The front end of the conveying support roller 2 passes through the conveying frame 1 and extends to the front side of the conveying frame 1. A transmission chain box 3 is installed on the front side of the conveying frame 1 to drive the conveying support roller 2 to rotate. A transmission motor 4 is installed on the front side wall of the transmission chain box 3. A support steering device 7 for supporting the sheet metal for rotational spraying is installed in the middle of the conveying frame 1. Spray nozzles for spraying are provided on both sides of the support steering device 7 within the spraying chamber. An auxiliary support plate 6 is provided on the outer side of the support steering device 7 to facilitate the transition of the sheet metal between the conveying support roller 2 and the support steering device 7.

[0026] Furthermore, the support steering device 7 includes an adjustable support device 71, a support shaft 72, a support plate frame 73, a rotary motor 74, a drive gear 75, and a moving meshing gear 76. The adjustable support device 71 is installed above the support base 10 located in the middle position. The support shaft 72 is installed to the output end of the adjustable support device 71 via bearings. The support plate frame 73 is installed at the top of the support shaft 72. The rotary motor 74 is installed above the support base 10 and located behind the adjustable support device 71. The drive gear 75 is installed to the output end of the rotary motor 74. The moving meshing gear 76 is located on the outer periphery of the support shaft 72. The drive gear 75 meshes with the moving meshing gear 76. The support steering device 7 lifts the plate upwards, and after lifting, drives the plate to rotate, thereby performing spraying work on the surface of the plate.

[0027] Furthermore, an auxiliary transmission shaft 8 is rotatably mounted on the inner wall of the conveyor frame 1 and below the auxiliary support plate 6 via bearings. The front end of the auxiliary transmission shaft 8 is connected to the transmission chain box 3. A transmission roller 9 is installed on the outer wall of the auxiliary transmission shaft 8. A through-hole 11 is provided at the top of the support plate frame 73. The transmission roller 9 extends to the top of the support plate frame 73 through the through-hole 11. After the plate is transferred to the top of the support plate frame 73, the auxiliary transmission shaft 8 drives the transmission roller 9 to rotate, and the transmission roller 9 transmits the plate to the center position above the support plate frame 73.

[0028] Furthermore, both the transition plate 5 and the auxiliary support plate 6 are inlaid with balls on their tops. The tops of the balls are on the same plane as the tops of the conveying support roller 2. Through the cooperation of the transition plate 5 and the auxiliary support plate 6, a continuous support surface is formed for the plate, reducing the shaking in the transmission gap and improving the transmission stability of the plate.

[0029] Furthermore, the auxiliary support plate 6 is composed of multiple strip plates assembled together and fixed with bolts.

[0030] Furthermore, the thickness of the movable meshing gear 76 is greater than that of the drive gear 75. After the movable meshing gear 76 moves up and down, it can maintain the meshing state with the drive gear 75. The control support device 71 controls the support shaft 72 to push the support plate frame 73 to move upward and lift the plate. The rotary motor 74 drives the support shaft 72 to rotate through the cooperation of the drive gear 75 and the movable meshing gear 76. The support shaft 72 drives the support plate frame 73 to rotate, and the support plate frame 73 drives the plate to rotate, thereby completing the spraying and sealing work on the side of the plate.

[0031] Furthermore, the rotary motor 74 is a servo motor. The rotary motor is controlled by numerical control. The rotation speed of the different sides of the board when it is pointing towards the nozzle is proportional to the size of the corresponding side of the board. For example, when the larger side of the board turns towards the nozzle, the rotary motor automatically slows down to extend the spraying time and improve the uniformity of the coating.

[0032] In use, the rotation speed of the rotary motor 74 is adjusted according to the outer dimensions of the material to be coated, allowing for adjustable coating time on each side of the material based on its area. The material is placed above the conveyor support roller 2, and then the transmission motor 4 is started. The transmission motor 4 drives the conveyor support roller 2 to rotate via the transmission chain box 3, pushing the material to the right along the conveyor support roller 2. As the material moves to the right, it is supported by the ball bearings on the top of the transition plate 5. After the material moves above the support plate frame 73, it contacts the top of the transmission roller 9. The transmission chain box 3 drives the auxiliary transmission shaft 8 to rotate, which in turn drives the transmission roller 9 to rotate, moving the material to the center position above the support plate frame 73. The transmission motor 4 is then stopped, and the support device 71 controls the support shaft 72 to push the support plate frame 73 upward, lifting the material. The rotary motor 74 drives the gears... The engagement of wheel 75 and moving meshing gear 76 drives the support shaft 72 to rotate. At this time, the control support device 71 controls the support shaft 72 to push the support plate frame 73 away from the transmission roller 9, lifting the plate upward. Then, the rotary motor 74 drives the drive gear 75 to rotate, which in turn drives the moving meshing gear 76 to rotate. The moving meshing gear 76 drives the support plate frame 73 to rotate via the support shaft 72, and the support plate frame 73 drives the plate to rotate. Simultaneously, the spray head sprays each side of the plate according to the preset program. After spraying is completed, the control support device 71 drives the support shaft 72 to move downward, and then the support plate frame 73 drives the plate downward back to the transmission roller 9. Then, the transmission motor 4 is started again, and the transmission roller 9 continues to rotate, transmitting the plate to the right above the right-side conveying support roller 2. The plate is then conveyed out via the right-side conveying support roller 2. The transmission process is smooth, thereby improving the efficiency and quality of the plate spraying and sealing.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
