Description

Technical Field

[0001] This utility model relates to the field of aluminum profile production technology, and in particular to a fan cooling device for the slide table of aluminum profile extrusion equipment. Background Technology

[0002] During the aluminum profile extrusion process, the temperature of the aluminum profile at the outlet of the extrusion equipment can reach over 520℃. The extruded aluminum profile needs to be cooled down rapidly at the slide table to meet the hardness requirements and subsequent production needs.

[0003] Currently, the commonly used fan cooling devices located on the sliding platform have fixed air nozzles. In order not to affect the operation of workers when manually pulling aluminum profiles, the air nozzles located above the conveyor belt on the sliding platform need to be a certain distance away from the conveyor belt. Because the air nozzles are far away from the conveyor belt, the air outlet of the air nozzles will quickly attenuate, resulting in insufficient cooling capacity of the air blowing on the aluminum profiles on the conveyor belt. Utility Model Content

[0004] In order to overcome the defects of the existing technology, this utility model provides a fan cooling device for the slide table of aluminum profile extrusion equipment to solve the above problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a fan cooling device for the slide table of an aluminum profile extrusion equipment, including an upper air module disposed on the upper side of the slide table, the upper air module including a first mixed flow fan, a first air duct unit, a flexible connecting round pipe and an upper air nozzle arranged sequentially from top to bottom; The air outlet of the first mixed-flow fan is connected to the air inlet of the first air duct unit. The first air duct unit is provided with multiple air outlets. Each air outlet of the first air duct unit is paired with a flexible connecting pipe. The air inlet of the flexible connecting pipe is connected to the air outlet of the first air duct unit. The air outlet of the flexible connecting pipe is connected to the cold air inlet of the upper air nozzle. The cold air outlet of the upper air nozzle faces the upper side of the sliding table.

[0006] It is worth noting that the upper air nozzle includes a collecting air inlet and multiple head air outlets. The multiple head air outlets are located at the lower end of the collecting air inlet and are connected to the collecting air inlet. The upper end of the collecting air inlet is connected to the air outlet of the flexible connecting round pipe. The cold air outlet of the upper air nozzle is located at the end of the head air outlet that is away from the collecting air inlet.

[0007] Preferably, the lower end of the air inlet is evenly distributed with three head outlets, and the included angle α formed between two adjacent head outlets is in the range of [60°, 90°].

[0008] Optionally, the upper air nozzle further includes a connecting protruding tube, which is disposed at the upper end of the air inlet and is inserted into the air outlet of the flexible connecting tube and is interference-fitted with the air outlet of the flexible connecting tube.

[0009] It is worth noting that the interior of the head air outlet is provided with multiple parallel guide strips to form multiple cold air outlets at the end of the head air outlet that is away from the air inlet.

[0010] Specifically, a downdraft module is provided on the lower side of the sliding table, and the downdraft module includes a second mixed-flow fan, a second air duct unit and a downdraft nozzle arranged sequentially from bottom to top; The outlet of the second mixed-flow fan is connected to the inlet of the second air duct unit. The second air duct unit is provided with multiple outlets. Each outlet of the second air duct unit is paired with a lower air nozzle. The outlet of the second air duct unit is connected to the inlet of the lower air nozzle. The outlet of the lower air nozzle faces the lower side of the sliding table.

[0011] Preferably, temperature sensors are provided on the lower side of the first air duct unit and the upper side of the second air duct unit.

[0012] The beneficial effects of this utility model are as follows: In the fan cooling device for the sliding table of the aluminum profile extrusion equipment, since a flexible connecting round tube is set between the first air duct unit and the upper air nozzle, the upper air nozzle can be set closer to the sliding table. By designing the length of the flexible connecting round tube, the positional relationship between the upper air nozzle and the aluminum profile can be kept within the optimal spatial distance, thereby improving the cooling capacity. When manually pulling the material, since the flexible connecting round tube is set, it allows the flexible connecting round tube to drive the upper air nozzle to swing flexibly in the horizontal and vertical directions while maintaining airtightness. This avoids obstructing the worker's operating space and also avoids reducing the cooling capacity. Attached Figure Description

[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0015] like Figure 1-7 As shown, a fan cooling device for the slide table of an aluminum profile extrusion equipment includes an upper air module 2 disposed on the upper side of the slide table 1. The upper air module 2 includes a first mixed flow fan 21, a first air duct unit 22, a flexible connecting round pipe 23 and an upper air nozzle 24 arranged sequentially from top to bottom. The air outlet of the first mixed-flow fan 21 is connected to the air inlet of the first air duct unit 22. The first air duct unit 22 is provided with multiple air outlets. Each air outlet of the first air duct unit 22 is paired with a flexible connecting round pipe 23. The air inlet of the flexible connecting round pipe 23 is connected to the air outlet of the first air duct unit 22. The air outlet of the flexible connecting round pipe 23 is connected to the cold air inlet end of the upper air nozzle 24. The cold air outlet end 241 of the upper air nozzle 24 faces the upper side of the sliding table 1.

[0016] In the fan cooling device for the slide table of the aluminum profile extrusion equipment, a flexible connecting tube 23 is provided between the first air duct unit 22 and the upper air nozzle 24. This allows the upper air nozzle 24 to be positioned closer to the slide table 1. By designing the length of the flexible connecting tube 23, the positional relationship between the upper air nozzle 24 and the aluminum profile can be maintained within the optimal spatial distance, thereby improving cooling capacity. During manual material handling, the flexible connecting tube 23 allows the upper air nozzle 24 to swing flexibly in both horizontal and vertical directions while maintaining airtightness. This avoids obstructing the worker's operating space and also prevents a reduction in cooling capacity. In this embodiment, the horizontal direction refers to the direction in which the aluminum profile is conveyed on the slide table, and the vertical direction refers to the direction perpendicular to the conveying direction of the aluminum profile.

[0017] Specifically, the flexible connecting tube 23 is a silicone fiberglass cloth flexible tube. In this embodiment, the first air duct unit 22 is a hollow structure with an air inlet on its upper side and multiple air outlets on its lower side. The cold air generated by the first mixed flow fan 21 enters the interior of the first air duct unit 22 through the air inlet of the first air duct unit 22 from the air outlet of the first mixed flow fan 21. Utilizing the principle of pressure, the cold air is simultaneously blown out from the multiple air outlets of the first air duct unit 22, thus entering the flexible connecting tube 23 paired with each air outlet. Then, after passing through the air outlet of the flexible connecting tube 23, it enters the interior of the upper air nozzle 24 from the cold air inlet end of the upper air nozzle 24, and finally is blown out from the cold air outlet end 241 of the upper air nozzle 24 onto the upper surface of the aluminum profile located on the sliding table 1, thereby cooling the aluminum profile.

[0018] Preferred, such as Figure 2 As shown, the upper air nozzle 24 includes a collecting air inlet 242 and multiple head air outlets 243. The multiple head air outlets 243 are disposed at the lower end of the collecting air inlet 242 and communicate with the collecting air inlet 242. The upper end of the collecting air inlet 242 is communicated with the air outlet of the flexible connecting round tube 23. The cold air outlet 241 of the upper air nozzle 24 is disposed at the end of the head air outlet 243 away from the collecting air inlet 242.

[0019] After the cold air enters the air inlet 242, it is drawn into multiple head outlets 243 simultaneously using the principle of pressure. The air is then output from the end of each head outlet 243 furthest from the air inlet 242 and blown onto the aluminum profile located on the sliding platform 1. By providing multiple head outlets 243, the cooling range of the cold air blown from a single top nozzle 24 can be increased.

[0020] Optional, such as Figure 4 As shown, three head air outlets 243 are evenly distributed at the lower end of the air inlet 242, and the included angle α formed between two adjacent head air outlets 243 is in the range of [60°, 90°]. Specifically, among the three head air outlets 243 arranged in the same upper air nozzle 24, the end of the middle head air outlet 243 away from the air inlet 242 is vertically downward, and the other two head air outlets 243 are evenly distributed on both sides of the middle head air outlet 243, and each forms an included angle α with the middle head air outlet 243. Therefore, the two head air outlets 243 on both sides of the middle head air outlet 243 are inclined to increase the cooling range of the cold air blown out by a single upper air nozzle 24, thereby increasing the coverage area of ​​the blown cold air on the surface of the aluminum profile, and thus increasing the cooling capacity of the aluminum profile.

[0021] It is worth noting that, such as Figure 4 and5 As shown, the upper air nozzle 24 also includes a connecting protrusion 244, which is located at the upper end of the air inlet and outlet assembly 242. The connecting protrusion 244 is inserted into the air outlet of the flexible connecting tube 23 and is interference-fitted with the air outlet of the flexible connecting tube 23. By providing the connecting protrusion 244, the upper air nozzle 24 can be easily connected to the flexible connecting tube 23, and the interference fit can increase the sealing performance at the connection between the upper air nozzle 24 and the flexible connecting tube 23.

[0022] Preferably, the interior of the head air outlet 243 is provided with a plurality of parallel guide strips 245 to form a plurality of cold air outlets 241 at the end of the head air outlet 243 away from the collecting air inlet 242. Figure 3 and 5 As shown, each head air outlet 243 is strip-shaped and extends perpendicular to the conveying direction of the aluminum profile, thus adapting to the width of the aluminum profile. By setting the guide strip 245, the end of the head air outlet 243 away from the collecting air inlet 242 is divided into multiple cold air outlet ends 241, so that the cross-sectional area of ​​a single cold air outlet end 241 is smaller than that of the end of the head air outlet 243 away from the collecting air inlet 242, according to the continuity equation (flow rate = velocity). (Cross-sectional area), when the total flow rate remains constant, reducing the area of ​​a single cold air outlet 241 can significantly increase the airflow velocity.

[0023] Specifically, such as Figure 2 As shown, a downdraft module 3 is provided on the lower side of the sliding table 1. The downdraft module 3 includes a second mixed-flow fan 31, a second air duct unit 32 and a downdraft nozzle 33 arranged sequentially from bottom to top. The air outlet of the second mixed-flow fan 31 is connected to the air inlet of the second air duct unit 32. The second air duct unit 32 is provided with multiple air outlets. Each air outlet of the second air duct unit 32 is paired with a lower air nozzle 33. The air outlet of the second air duct unit 32 is connected to the air inlet of the lower air nozzle 33. The air outlet of the lower air nozzle 33 faces the lower side of the sliding platform 1.

[0024] The second air duct unit 32 is a hollow structure with an air inlet on its lower side and multiple air outlets on its upper side. The cold air generated by the second mixed-flow fan 31 enters the second air duct unit 32 through its air inlet and, utilizing the principle of pressure, is simultaneously blown out from the multiple air outlets of the second air duct unit 32, thus entering the lower air nozzle 33 paired with each air outlet. Finally, the air is blown out from the outlet of the lower air nozzle 33 onto the lower surface of the aluminum profile located on the sliding table 1, thereby cooling the lower surface of the aluminum profile. Combined with the upper air module 2, this further enhances the cooling capacity of the cooling device. Specifically, as... Figure 6 and 7 As shown, the lower air nozzle 33 can also include three evenly distributed head air outlets 243. Furthermore, the interior of the three head air outlets 243 corresponding to the lower air nozzle 24 is also provided with guide strips 245, the principle of which is the same as that of the three head air outlets 243 on the upper air nozzle 24, and will not be elaborated further here. The original roller of the sliding table 1 can be positioned between two adjacent head air outlets 243 in the upper air nozzle 24. This installation does not affect the operation of the original roller of the sliding table, and minimizes the distance between the head air outlets 243 and the aluminum profile located on the roller, thus minimizing the cooling distance. The optimized wind resistance design (i.e., the provision of guide strips 245) to increase wind speed, combined with the design that shortens the distance from the lower air nozzle 24 to the aluminum profile, thereby improving the cooling capacity.

[0025] It is worth noting that, such as Figure 2 As shown, temperature sensors 34 are provided on the lower side of the first air duct unit 22 and the upper side of the second air duct unit 32. The temperature sensors 34 can collect the temperature around the lower side of the first air duct unit 22 and the upper side of the second air duct unit 32 to reflect the temperature of the surface of the aluminum profile located on the sliding table 1.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
