[0033] 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.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a high-efficiency primer dryer, comprising a housing 1, the housing 1 having a hollow inner cavity structure in the middle, and support legs at the four corners of the bottom end for raising the housing 1. A transmission mechanism 2 is provided in the middle of the housing 1, the transmission mechanism 2 being a sprocket and chain meshing mechanism that drives multiple support plates to rotate clockwise, thereby achieving a transmission effect.

[0035] A hot air blower 3 is installed at the top of the casing 1. The hot air blower 3 is one of the main heat sources for the drying equipment. After startup, the blower draws in outside air, heats it through internal heating elements, and rapidly raises the air temperature to become hot air, which is then blown out through the air outlet. A mesh box 4 is fixedly connected inside the casing 1. The mesh box 4 is U-shaped with openings at the top and sides. The left and right sides of the mesh box 4 are fixed to the left and right sides of the inner cavity of the casing 1, and after being fixed by the inner cavity, it is placed suspended above the inner cavity of the casing 1. The mesh box 4 is fitted around the middle of the outer side of the transmission mechanism 2, with the transmission mechanism 2 located in the middle area of ​​the mesh box 4. The two structures do not contact each other. Temperature controllers 5 are installed on both the front and rear sides of the interior of the casing 1. Heating tubes 6 are fixedly connected to the output end of the temperature controller 5. The surface of the temperature controller 5 has a display screen and operation buttons for setting and displaying the heating temperature.

[0036] The temperature controller 5 contains a temperature sensor and control circuit, which is connected to the heating element 6 via a cable. The heating element 6 is externally fixedly connected to the front and rear sides of the interior of the housing 1, located between the mesh box 4 and the inner cavity of the housing 1. Under the control of the temperature controller 5, the heating element 6 is energized and heats up, heating the front and rear inner wall areas of the housing 1, working in conjunction with the hot air blown out by the hot air blower 3. A square frame 7 is fixedly connected to the top of the mesh box 4. The square frame 7 and the mesh box 4 work together to further divert and guide the hot air blown out by the hot air blower 3.

[0037] refer to Figure 4 , Figure 5 Multiple rotating rollers 8 are rotatably connected inside the frame 7. The length of the rollers 8 is slightly longer than the internal width of the frame 7 to ensure that they do not detach from the wall of the frame 7 during rotation. A swing blade 9 is fixedly connected to the outside of the rollers 8. The front and rear sides of the swing blade 9 are slidably connected to the inner wall of the middle part of the frame 7. When the swing blade 9 swings, the rotating roller 8 serves as the axis of rotation for the swing blade 9, making the swing blade 9 rotate more smoothly and steadily within the inner wall of the frame 7. Furthermore, the swinging motion of the swing blade 9 effectively improves the utilization rate of hot air, accelerates the drying process of the primer, and improves drying efficiency and quality.

[0038] A connecting roller 10 is fixedly connected to the top center of the oscillating blade 9. A connecting rod 11 is fixedly connected to the rear end of multiple connecting rollers 10. The connecting rollers 10 facilitate smoother connection and transmission between the oscillating blade 9 and the rotating roller 8. A convex roller 12 is fixedly connected to the rear center of the connecting rod 11. The convex roller 12 is fixedly attached to the outside of the convex roller 12, and the convex roller 12 and the slider 13 are combined to form a T-shaped structure.

[0039] A drive assembly for adjusting the rotation amplitude of the oscillating blade 9 is provided at the rear top of the frame 7. The drive assembly includes a motor 14, the outer bottom end of which is fixedly connected to the rear top of the frame 7, providing a mounting position for the motor 14. A circulation groove rod 15 is fixedly connected to the drive end of the motor 14, and the circulation groove rod 15 has a circulating wave groove on its outer side. A protective cover 16 is fixedly connected to the rear top of the frame 7 by welding, providing a relatively enclosed protective space for the internal transmission components and preventing dust, debris, etc. from entering and affecting their normal operation.

[0040] The protective cover 16 has a sliding connection of a limiting ring 17 inside. A guide roller 18 is fixedly connected to the middle of the rear side of the limiting ring 17. The guide roller 18 is slidably connected to the outside of the circulating groove rod 15. The limiting ring 17 can move stably between the circulating groove rod 15 and the protective cover 16 under the drive of the guide roller 18.

[0041] Two push rods 19 are fixedly connected to the upper and lower sides of the limiting ring 17. The movement of the push rods 19 is controlled by the guide roller 18 via the limiting ring 17. The outer side of the push rod 19 is slidably connected to the protective cover 16 on the side away from the motor 14, thus limiting the direction of sliding of the push rod 19. A limiting block 20 is fixedly connected to the side of the two push rods 19 away from the motor 14. A guide rod 21 is fixedly connected inside the limiting block 20. The middle part of the slider 13 is slidably connected to the outside of the guide rod 21. The guide rod 21 provides a fixed track along which the slider 13 can slide.

[0042] refer to Figure 2 , Figure 6 Two retaining blocks 22 are fixedly connected to the left and right sides of the outer side of the casing 1, located at the opening and outlet of the casing 1. A support block 23 is fixedly connected to the top of each retaining block 22, supporting and fixing a second motor 24. The second motor 24 is fixedly connected to the front side of the support block 23, starting or stopping the movement of the shielding curtain 26 according to a signal from the controller. A winding shaft 25 is fixedly connected to the drive end of the second motor 24, responsible for winding up or lowering the shielding curtain 26 to allow the wooden boards to enter or leave the dryer. The front and rear sides of the winding shaft 25 are rotatably connected to the adjacent sides of the two support blocks 23, a design that ensures stable rotation of the winding shaft 25. A shielding curtain 26 is installed outside the winding shaft 25, slidingly connected to the adjacent side of the retaining blocks 22. The shielding curtain 26 slides within the retaining blocks 22 to prevent heat loss from the dryer or to prevent the entry of cold air from outside.

[0043] A humidity monitor 27 is installed on the outer left side of the casing 1. The humidity monitor 27 is electrically connected to motor 24. The humidity monitor 27 monitors the humidity on the furniture boards and transmits the information to motor 24 at the entrance, thereby activating motor 24 to open and close the curtain 26 in time to prevent heat loss. An object scanner 28 is installed on the outer right side of the casing 1. The object scanner 28 is electrically connected to motor 24. The object scanner 28 detects whether the furniture boards have moved into place and transmits the information to motor 24 at the exit to activate it in time, allowing the boards to flow out smoothly.

[0044] Working Principle: First, connect to an external power source and control the hot air blower 3 to start the preheating process via the controller. After the hot air blower 3 starts operating, part of the hot air blows directly downwards, while the other part, guided by the grid box 4 and the frame 7, flows to the front and rear cavities of the casing 1, continuing downwards until it reaches the bottom of the inner cavity of the casing 1. Finally, through the holes in the grid box 4, it achieves a surround heating effect on the central area of ​​the casing 1. During this preheating stage, the temperature controller 5 also starts simultaneously, precisely controlling the heating tube 6 to heat the front and rear inner walls of the casing 1, thereby enhancing the preheating efficiency of the hot air blower 3 and allowing the temperature inside the casing 1 to rise quickly and evenly, creating a suitable thermal environment for subsequent drying operations. At the same time, motor 14 and hot air blower 3 start simultaneously. Motor 14 drives the circulating groove rod 15 to start rotating, and the guide roller 18 fixed by the limiting ring 17 will slide repeatedly left and right along the groove on the outside of the circulating groove rod 15 under the drive of the rotation of the circulating groove rod 15. As the guide roller 18 slides left and right, the top rod 19 fixed by the limiting ring 17 will also reciprocate and extend within the inner wall of the protective cover 16, thereby driving the slider 13 sliding on the guide rod 21 inside the limiting block 20 to slide within the inner wall of the limiting block 20. This series of linkages allows the slider 13 to slide left and right synchronously via the connecting rod 11 connected to the convex roller 12. The left and right sliding of the connecting rod 11 will cause the multiple connecting rollers 10 connected to it to rotate, driving the swing blades 9 to rotate around the rotating roller 8. The rotation of the swing blades 9 occurs in the central area of ​​the frame 7, thereby efficiently dispersing the airflow blown downwards by the hot air blower 3, ensuring that the hot airflow can be evenly distributed in all corners of the inner cavity of the casing 1, avoiding local overheating or overcooling, and ensuring the uniformity and stability of the drying environment.

[0045] Once the inner cavity of housing 1 has been preheated to the set temperature, the conveyor mechanism 2 is activated, and the painted furniture board is placed on top of the conveyor mechanism 2. As the conveyor mechanism 2 operates, the furniture board gradually moves towards the inner cavity of housing 1. When the furniture board approaches housing 1, the humidity monitor 27 located at the entrance of housing 1 detects the undried paint on the furniture board. The humidity monitor 27 then transmits this information to the controller. After rapid processing, the controller sends a command to motor 24 at the entrance. Motor 24 starts and drives the winding shaft 25 to rotate. The winding shaft 25 winds up the blind curtain 26, ensuring that the furniture board does not rub against the blind curtain 26 as it enters housing 1, thus ensuring the furniture board smoothly enters the drying area. Furthermore, once the wood board is fully inside the housing 1, the humidity monitor 27 can no longer detect its presence and will transmit information to the second motor 24 at the entrance. Upon receiving the instruction, the second motor 24 starts and drives the curtain 26 to be lowered in time, effectively preventing heat loss from the housing 1 and ensuring that the temperature inside the housing 1 can be maintained within a suitable drying temperature range. This ensures that the wood board can be fully and evenly heated in a stable thermal environment, guaranteeing the drying quality of the primer.

[0046] When the heating process inside the housing 1 is completed, the furniture board moves to the outlet of the housing 1 along with the conveyor mechanism 2. The object scanner 28 will quickly scan the movement of the board and transmit this information to the motor 24 at the outlet. At this time, the motor 24 at the outlet will drive the curtain 26 to start and open in time, so that the dried board can flow out of the housing 1 smoothly and enter the next process to complete the entire primer drying process, ensuring the efficient, stable and continuous operation of the production process.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
