Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0026] The present application embodiment discloses a cooling device for epoxy powder coating. Figure 1 A cooling device for epoxy powder coating comprises a bracket 1, a conveyor belt 2 is rotatably connected to the bracket 1, and the conveyor belt 2 uses a chain plate conveyor belt 2 to convey the coating. The conveyor belt 2 is respectively connected to a twin-screw extruder 5 and a tablet crusher (not shown in the figure) at both ends along the length direction, and the conveyor belt 2 transports the material extruded by the twin-screw extruder 5 to the tablet crusher.

[0027] refer to Figure 1A cooling component 3 and a deviation correction component 4 are arranged above the conveyor belt 2. The cooling component 3 effectively cools the paint on the conveyor belt 2; the deviation correction component 4 enables the paint to be promptly and effectively corrected back to the correct path when it deviates, providing a stable foundation for subsequent paint processing.

[0028] refer to Figure 1 The cooling assembly 3 is fixed to the bracket 1. The cooling assembly 3 includes three groups of cooling parts arranged in sequence along the length direction of the conveyor belt 2, namely the first cooling part 31, the second cooling part 32 and the third cooling part 33. The first cooling part 31 includes two cooling fans 311 arranged side by side. The cooling fans 311 are located directly above the conveyor belt 2. The two cooling fans 311 are symmetrically arranged on both sides of the center line of the width direction of the conveyor belt 2, and the air outlets of the cooling fans 311 face the upper surface of the conveyor belt 2. The first cooling part 31 is used to perform preliminary cooling on the paint on the conveyor belt 2. The second cooling part 32 and the third cooling part 33 each include two cooling fans 331 arranged side by side. The two cooling fans 331 of each cooling part are symmetrically arranged on both sides of the center line of the width direction of the conveyor belt 2, which are used to further air cool the paint. Through the sequential arrangement of the three cooling parts, the gradual cooling of the paint is achieved, the cooling effect is improved, and it is ensured that the paint can be effectively cooled, avoiding the paint quality problems that may be caused by uneven cooling or rapid cooling.

[0029] refer to Figure 1 and 2The deviation correction component 4 includes an adjustment roller 41, and the adjustment roller 41 is located between the second cooling part 32 and the third cooling part 33. An adjustment frame 42 is fixedly connected to the position corresponding to the adjustment roller 41 on the bracket 1. The adjustment frame 42 is arranged in the width direction of the transmission belt, and the crossbeam of the adjustment frame 42 is located above the conveyor belt 2. A sliding rail 421 is rotatably connected below the crossbeam of the adjustment frame 42. The upper side of the sliding rail 421 abuts against the lower side of the crossbeam of the adjustment frame 42. A connecting rod is fixedly connected to the sliding rail 421 at the middle position along the length direction. The connecting rod is upwardly penetrated through the crossbeam of the adjustment frame 42 and fixedly connected with a gear. A first servo motor 4211 is fixedly provided at the position corresponding to the gear at the upper end of the adjustment frame 42. The first servo motor 4211 drives the gear to rotate, thereby driving the sliding rail 421 to rotate in the horizontal direction with the connecting rod as the rotating axis. A slide groove is provided at the lower side of the slide rail 421, and the slide groove is arranged along the length direction of the slide rail 421. A clamping frame 422 is slidably connected in the slide groove, and the clamping frame 422 is clamped at both ends of the adjustment roller 41, and the adjustment roller 41 is rotatably connected to the clamping frame 422. A rack is fixedly provided on one side of the clamping frame 422, and the rack is arranged in a horizontal direction. A second servo motor 4221 is fixedly provided on the slide rail 421, and a gear that can mesh with the rack is fixedly connected to the output end of the second servo motor 4221. The second servo motor 4221 drives the clamping frame 422 to slide along the length direction of the slide rail 421 through the meshing of the gear and rack. When correcting the deviation, the first servo motor 4211 is started according to the offset direction of the paint, so that the slide rail 421 rotates in the opposite direction of the paint offset. After the rotation is completed, the second servo motor 4221 is started, and the second servo motor 4221 drives the clamping frame 422 to make reciprocating linear motion along the length direction of the sliding rail 421, and the peripheral surface of the adjustment roller 41 abuts against the surface of the paint, guiding the paint that is being cooled and hardened to the correct direction. After the correction is completed, the first servo motor 4211 is started, and the sliding rail 421 is rotated so that the sliding rail 421 returns to the initial position set along the length direction of the conveyor belt 2. The adjustment roller 41 can perform preliminary correction on the extruded and cooled paint to ensure the stability of the paint during the subsequent transmission process.

[0030] refer to Figure 1 The correction component 4 also includes a correction roller 43, which is used to perform further correction during the coating transmission process and cooperates with the adjustment roller 41 to form a correction effect.

[0031] refer to Figure 1Specifically, four deflection correction rollers 43 are provided, and the deflection correction rollers 43 appear in pairs. Two pairs of deflection correction rollers 43 are located at one side of the first cooling part 31 and the second cooling part 32 along the transmission direction of the conveyor belt 2. Each pair of deflection correction rollers 43 are symmetrically arranged on the bracket 1 on both sides of the conveyor belt 2. A connecting frame 431 is fixedly provided on the bracket 1 at the position corresponding to the deflection correction roller 43, and the deflection correction roller 43 is rotatably connected to the connecting frame 431. The deflection correction rollers 43 are arranged along the length direction of the conveyor belt 2, and the deflection correction rollers 43 are arranged close to each other along the transmission direction of the conveyor belt 2. The axes of the deflection correction rollers 43 are arranged parallel to the upper surface of the conveyor shaft, and the circumferential surface of the deflection correction rollers 43 can be connected to the upper surface of the conveyor belt 2. A driving motor is fixedly provided on the connecting frame 431, and the output end of the driving motor is fixedly connected to one end of the deflection correction roller 43. The driving motor drives the deflection correction roller 43 to rotate toward the center position of the conveyor belt 2 along the width direction at the position where the deflection correction roller 43 abuts against the conveyor belt 2. When the paint deviates during the transmission process, the deviated paint abuts against the correction roller 43 in the deviated direction under the drive of the conveyor belt 2, and the correction roller 43 rotates to push the deviated paint toward the center direction of the conveyor belt 2 along the width direction, thereby correcting the paint back to the correct transmission path. By setting two pairs of correction rollers 43 at intervals on the paint transmission path, multi-point correction of the paint during the cooling transmission process is achieved, further increasing the accuracy and reliability of correction, and ensuring that the paint can remain on the correct path during the entire transmission process.

[0032] The implementation principle of the embodiment of the present application is as follows: during the transmission of the epoxy powder coating on the conveyor belt 2, it is first preliminarily cooled by the first cooling section 31, and then further cooled by the second cooling section 32 and the third cooling section 33. During the cooling process, the adjustment roller 41 performs a preliminary deviation correction on the coating to ensure that it is transmitted on the correct path. Subsequently, the coating passes through the deviation correction rollers 43, which perform further deviation correction on both sides of the coating transmission path to ensure that the coating does not deviate out of the predetermined transmission range. Through this structural configuration, the cooling device of this embodiment can not only achieve gradual and efficient cooling of the coating, but also effectively solve the problem of coating deviation during the transmission process, thereby improving the production efficiency and product quality of the coating.

[0033] Reference Figure 1 As a further example of this embodiment, the surfaces of the deflection correction roller 43 and the adjustment roller 41 are provided with anti-skid textures. These anti-skid textures can increase the friction between the deflection correction roller 43 and the adjustment roller 41 and the coating, preventing the coating from sliding or falling off during the deflection correction process, thereby further improving the deflection correction effect and stability.

[0034] Reference Figure 1As a further example under this embodiment, the speed of the cooling fan 331 is adjustable. By adjusting the speed of the cooling fan 331, the cooling requirements of different coatings in different production environments can be met. For example, when the coating thickness is large or the production environment temperature is high, the speed of the cooling fan 331 can be appropriately increased to increase the cooling air volume and improve the cooling effect. Conversely, when the coating thickness is small or the production environment temperature is low, the speed of the cooling fan 331 can be appropriately reduced to avoid overcooling of the coating and quality problems.

[0035] Reference Figure 1 As a further example under this embodiment, baffles 11 are provided on both sides of the conveyor belt 2, and these baffles 11 are arranged along the length direction of the conveyor belt 2. The function of the baffles 11 is to further prevent the paint from leaking or splashing during the transmission process, and ensure that the paint can be completely and evenly affected by the cooling air, thereby improving the cooling effect and product quality.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
