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.

[0015] Please see Figures 1-7 The present invention provides the following technical solution: an adhesive baking and curing device, including a curing box 1, a conveying roller 2 connected to both the left and right ends of the curing box 1, a drive motor 3 installed at the left rear end of the curing box 1, the output end of the drive motor 3 connected to one end of the conveying roller 2, a conveyor belt 4 attached to the outside of the conveying roller 2, a placement groove 5 opened on the conveyor belt 4, and automatic gates 6 installed at both the left and right ends of the curing box 1. A servo motor 7 is installed on the top of the curing chamber 1. The output end of the servo motor 7 is connected to a lead screw 8. A moving column 9 is threaded on the outside of the lead screw 8. An upper mounting bracket 10 is installed at the lower end of the moving column 9. A sliding rod 30 is connected to the end of the upper mounting bracket 10 away from the moving column 9. A fixed column 29 is sleeved on the outside of the sliding rod 30. The upper end of the fixed column 29 is connected to the curing chamber 1. A lower mounting bracket 13 is connected to the inner wall of the lower section of the curing chamber 1. Heating tubes 12 are installed on the inner walls of both the lower mounting bracket 13 and the upper mounting bracket 10. A blower 11 is installed on the upper side of the upper mounting bracket 10. A temperature sensor 14 is installed on the top inside the curing chamber 1. A temperature controller 15 and a relay 16 are installed on the outer surface of the curing chamber 1. Furthermore, the conveyor belt 4 has a mesh structure, and there is a gap between the conveyor belt 4 and the lower mounting frame 13, which allows the heating tube 12 on the lower mounting frame 13 to work smoothly, and the heat can come into contact with the workpiece on the conveyor belt 4 smoothly. An exhaust fan 17 is installed on the rear side of the curing box 1. The air inlet of the exhaust fan 17 is connected to an exhaust pipe 18. One end of the exhaust pipe 18 is connected to the top of the curing box 1. The air outlet of the exhaust fan 17 is connected to a conveying pipe 19. One end of the conveying pipe 19 is connected to a filter box 20. A through hole 28 is opened on the top of the filter box 20. A filter plate 21 is installed on the inner wall of the filter box 20. Furthermore, the filter plate 21 has a hollow structure inside, and the interior of the filter plate 21 is filled with activated carbon particles, which are used to filter and purify the exhaust gas. The lower end of the filter plate 21 is provided with an air inlet slot 23, and the upper end of the filter plate 21 is provided with an air outlet slot 22. Both the air outlet slot 22 and the air inlet slot 23 are equipped with mesh plates 24. Furthermore, the positions of the air outlet slot 22 and the air inlet slot 23 are staggered, and both the air outlet slot 22 and the air inlet slot 23 are connected to the hollow part of the filter plate 21, which can increase the flow path of the exhaust gas and fully treat the exhaust gas. The filter box 20 is internally connected to a rotating rod 25, one end of which is equipped with a fan blade 26, and the other end of which is equipped with a stirring rod 27; Furthermore, the fan blades 26 have an arc-shaped structure, and the fan blades 26 are distributed at equal angles on the rotating rod 25. The exhaust gas can be used to drive the fan blades 26 to rotate through the rotating rod 25. Furthermore, the stirring rod 27 is located inside the filter plate 21. The stirring rod 27 is coaxially connected to the fan blade 26. When the fan blade 26 rotates, the stirring rod 27 is controlled to rotate, thereby stirring the activated carbon particles and increasing the contact area between the exhaust gas and the activated particles. Specifically, when using the adhesive baking and curing equipment, the operator sets the preset temperature threshold range to 78-82℃ using the temperature controller 15. The workpiece coated with adhesive is placed in the workpiece placement slot 5 on the conveyor belt 4. The drive motor 3 is powered on, causing the conveyor roller 2 to rotate. The conveyor roller 2 drives the conveyor belt 4 to move, conveying the workpiece from the left opening of the curing chamber 1 into the curing chamber 1. After the workpiece enters the curing chamber 1, the automatic gate 6 at the left opening of the curing chamber 1 closes, while the automatic gate 6 at the right opening of the curing chamber 1 remains closed. The servo motor 7 is powered on, controlling its forward rotation, which drives the lead screw 8 connected to the output end to rotate. The lead screw 8 drives the moving column 9 connected by the outer thread to move downwards, thereby pushing the upper mounting bracket 10 downwards. At this time, the sliding rod 30 installed at one end of the upper mounting bracket 10 slides within the fixed column 29. To ensure stable movement of the upper mounting bracket 10, the position of the heating tube 12 is lowered. The servo motor 7 is reversed, which drives the lead screw 8 to reverse, thereby controlling the moving column 9 to move the upper mounting bracket 10 upward, raising the position of the heating tube 12 so that the heating tube 12 can adapt to the size adjustment of the workpiece and the distance between the workpiece. The temperature sensor 14 detects the temperature inside the curing chamber 1 in real time. When the detected temperature is below 78℃, the temperature controller 15 controls the relay 16 to close, and the heating tube 12 is powered on to heat. At the same time, the blower 11 starts to promote airflow inside the curing chamber 1, so that the temperature rises evenly. When the temperature rises to 82℃, the temperature controller 15 controls the relay 16 to open, and the heating tube 12 stops heating. This cycle is repeated to ensure that the temperature inside the curing chamber 1 is stable between 78-82℃. The workpiece moves slowly inside the curing chamber 1 with the conveyor belt 4, and the adhesive is baked and cured at a suitable temperature. After heat curing, the exhaust fan 17 is started, drawing the harmful waste gas generated by the adhesive in the curing chamber 1 into the filter chamber 20 through the exhaust pipe 18 and the conveying pipe 19. The waste gas drives the fan blade 26 to rotate through the rotating rod 25, and the waste gas enters the filter plate 21 through the air inlet slot 23, contacting the activated carbon particles in the filter plate 21 for filtration and purification. At the same time, the rotating rod 25 rotates, which drives the stirring rod 27 to rotate, stirring the activated carbon particles and dynamically purifying the gas. Finally, the gas is discharged from the air outlet slot 22, and the filtered gas is discharged to the outside through the through hole 28. When the workpiece is cured in the curing chamber 1 and is transported to the right end of the curing chamber 1, the automatic gate 6 at the right end of the curing chamber 1 opens, and the conveyor belt 4 transports the cured workpiece out of the curing chamber 1. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0016] Although the present invention 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 invention should be included within the protection scope of the present invention.
