Description

Technical Field

[0001] The invention belongs to the technical field of aluminum profile production and processing, and specifically relates to an environmentally friendly cooling device for aluminum profile processing. Background Art

[0002] After extrusion molding, the temperature of aluminum profiles is very high, and they need to be cooled before subsequent processing. In the prior art, after the aluminum profiles are extruded and discharged, they are generally conveyed by a conveying device to a cooling device for cooling. During cooling, after the aluminum profiles are driven into the cooling device, several groups of annular water spray structures are generally arranged equidistantly along the transportation direction of the aluminum profiles on the inner wall of the device, and cooling water or water mist is evenly sprayed around the aluminum profiles, and combined air cooling is performed in conjunction with the fan. However, this method cannot completely avoid the deformation or even fracture of the aluminum profiles that may occur during cooling. First, the annular water spray structures are equidistantly distributed, indicating that the water mist and water jet cannot completely cover the surface of the aluminum profiles at the same time. Internal stress will still appear at the junction of the various segmented cooling of the aluminum profiles, and since the aluminum profiles are placed horizontally, the water flow at the bottom of the aluminum profiles will always quickly drain away in the first place, which causes different water flow rates between different surfaces of the aluminum profiles, and their heat conduction efficiency is also different, which leads to that the uniformity of cooling cannot be optimal, which is easy to affect the uniformity of cooling of the aluminum profiles, and it is urgent to solve it.

[0026] like Figures 1 to 8As shown, an embodiment of the present invention provides an environmentally friendly cooling device for aluminum profile processing, including a working box 1 and a cooling water supply box 2 and a cooling water recovery box 3 located in front of the working box 1.

A mounting frame 17 is rotatably installed on the outer surface of the movable column 16. A plurality of power frames 21 are fixedly installed on the top of the mounting frame 17. A fixed column 18 is fixedly installed on the left side of the inner wall of 7, and a fixed column 20 located on the left side of the bracket 15 is fixedly connected to the inner wall of the working box 1. A telescopic rod 19 is rotatably installed on the outer surface of the fixed column 20, and the telescopic end of the telescopic rod 19 is rotatably installed on the outer surface of the fixed column 18. A connecting plate 33 is fixedly connected to the left side of the mounting frame 17, and an adapting column 32 is fixedly connected to the bottom of the connecting plate 33. The outer surface of the adapting column 32 is movably sleeved with a limiting cylinder 31, and the bottom of the limiting cylinder 31 is fixedly connected to the limiting plate 30. An adjusting plate 34 is fixedly installed at the bottom of the limiting plate 30, and a pillar 28 is fixedly connected to the bottom of the adjusting plate 34. The outer surface of the pillar 28 is movably sleeved with a receiving cylinder 26, and a roller 29 is movably installed at the bottom end of the receiving cylinder 26. The roller 29 rolls against the bottom of the inner wall of the working box 1, and a spring 27 is movably sleeved inside the receiving cylinder 26. The pillar 28 is elastically supported in the receiving cylinder 26 by the spring 27;

[0027] The device has been redesigned to improve the uniformity of cooling of various parts of the material surface during water cooling. The mounting frame 17 is supported by a telescopic rod 19, a fixed column 18 and a fixed column 20 for rotation as a whole, and the mounting frame 17 can be adjusted from a horizontal state to a tilted state with a low left and a high left state in cooperation with the bracket 15 and the movable column 16. In this state, the cooling water flowing from the transfer pipe 8 will flow from right to left along the tilted component of gravity after adhering to the surface of the material, so that all surfaces of the material can quickly contact the cooling water at the first time, which maintains the uniformity of the overall cooling of the material. At the same time, the flowing water will not exchange heat too quickly like the immersion method, avoiding deformation and cracking of the material. This design can achieve almost the same uniform cooling at various places on the surface of the material, thereby preventing the influence of internal stress on the material.

[0028] A fan 11 is installed on the right side of the top of the working box 1, and a connecting pipe 12 is fixedly connected to the air outlet end of the fan 11. The bottom end of the connecting pipe 12 penetrates downward to the bottom of the front and rear sides of the bottom of the inner wall of the working box 1, and is fixedly connected to two sets of exhaust slots 13. The air outlet of the exhaust slot 13 is inclined toward the mounting frame 17, and the inner wall of the exhaust slot 13 is fixedly connected to the isolation plate 14 that is equidistantly distributed in the longitudinal direction;

[0029] The exhaust slots 13 designed in the present device are arranged in two groups, which are inclined toward the transportation direction of the material, and the air outlets of the exhaust slots 13 are divided into multiple groups of isolation spaces by multiple groups of longitudinally distributed isolation plates 14, so as to provide fresh air for the inner cavity of the working box 1, reduce the influence of the high temperature of the material on the air temperature in the inner cavity of the working box 1, and provide fresh air through the fan 11, the connecting pipe 12 and the exhaust slots 13 to continuously replace the air heated by the material in the inner cavity of the working box 1, maintain the temperature environment of the inner cavity of the working box 1 constant, and provide a good temperature environment for material cooling.

[0030] The power racks 21 are arranged in multiple groups and are horizontally and equidistantly distributed on the top of the mounting frame 17. A motor 23 is installed on the front of the power rack 21. A transport roller 24 is rotatably installed inside the power rack 21. The output shaft of the motor 23 is connected to the transport roller 24 in a transmission manner. Two groups of limit rings 25 symmetrically distributed front and back are fixedly installed on the outer surface of the transport roller 24.

[0031] The power frame 21 is arranged in multiple groups, so as to provide rotation support and conveying power for the material, and the motor 23 drives the transport roller 24 to rotate and drives the material to be loaded and unloaded.

[0032] The bottom of the adjustment plate 34 is designed as an inclined plane with the left side lower and the right side higher, and the right sides of the limit plate 30 and the adjustment plate 34 are both in sliding contact with the mounting frame 17;

[0033] The inclined design at the bottom of the adjustment plate 34 is mainly to adapt to the pillar 28, the accommodating cylinder 26 and the roller 29. When the left side of the mounting frame 17 rotates downward, the adjustment plate 34 will be driven and rotated simultaneously under the action of the connecting plate 33, the adapter column 32 and the limit plate 30. The inclined design of the accommodating cylinder 26 and the pillar 28 can cooperate with the rotation of the roller 29 to prevent the occurrence of jamming.

[0034] The device is also provided with a limit plate 30 to provide a support and limit function when the material is tilted with the mounting frame 17. When the mounting frame 17 drives the material to rotate counterclockwise around the axis of the movable column 16 under the drive of the telescopic rod 19, the connecting plate 33, the adapter column 32, the limit cylinder 31 and the limit plate 30 are driven to rotate downward. At this time, the adapter column 32 will continue to penetrate into the limit cylinder 31, and under the elastic support of the spring 27 on the support column 28, the adjustment plate 34 and the limit plate 30, the limit plate 30 protrudes upward relative to the mounting frame 17, and the highest point of the limit plate 30 is higher than the outer surface of the transport roller 24. At this time, the vertical part of the limit plate 30 can just provide a limit support for one end of the material to prevent the material from sliding when tilted. At the same time, by driving the support column 28, the accommodating cylinder 26 and the roller 29 to rotate, the support column 28 continues to penetrate into the accommodating cylinder 26 and compresses the spring 27. At this time, the accommodating cylinder 26 is adapted through the roller 29.

[0035] The axis of the support column 28 and the receiving tube 26 is offset 2° to the left relative to the vertical line, the axis of the telescopic rod 19 is at an angle of 40° to the vertical line, and the fixing column 20 is located on the right side of the fixing column 18;

[0036] The angle between the axis of the support 28 and the vertical line can prevent the accommodating tube 26 from getting stuck when it is driven to rotate to the right. Figure 3 As shown, when the height of the left side of the mounting frame 17 decreases, the support 28, the receiving tube 26 and the roller 29 will tilt to the left as a whole. The axis of the support 28 is tilted to the left to prevent the receiving tube 26 from being stuck.

[0037] There are two limit cylinders 31 and two adapter columns 32, which are symmetrically distributed on both sides of the top of the limit plate 30, and the bottom end of the adapter column 32 can penetrate the bottom of the limit plate 30 downward.

[0038] The limiting cylinder 31 and the adapting column 32 are adapted to each other. When the mounting frame 17 drives the connecting plate 33 and the adapting column 32 to rotate downward, the limiting plate 30, the adjusting plate 34 and the supporting column 28 will be driven to rotate downward. At the same time, the adapting column 32 will also move downward relative to the inner wall of the limiting cylinder 31. At this time, the limiting plate 30 connected to the limiting cylinder 31 will move upward relative to the connecting plate 33 and the mounting frame 17, so that the limiting plate 30 is higher than the outer surface of the transport roller 24, thereby realizing the function of providing limiting support for the material.

[0039] The cross-sectional shape of the limiting plate 30 is "L"-shaped, and the highest point of the limiting plate 30 is lower than the highest point of the outer surface of the transport roller 24;

[0040] The "L"-shaped design of the limiting plate 30 enables it to provide limiting support for the material in a vertical state.

[0041] Among them, a protective tube 22 located outside the motor 23 is fixedly installed on the front of the power frame 21, and the protective tube 22 is longer than the motor 23;

[0042] The protective tube 22 just covers the outside of the motor 23 and is waterproof to protect the motor 23.

[0043] Working principle:

[0044] First, conveyor belts with a material transport height equal to that of the transport roller 24 are provided on both sides of the device. The material enters the right side of the inner cavity of the working box 1 along the transport direction and falls on the outer surface of the transport roller 24. The limiting ring 25 provides a limit, the motor 23 is started, and the transport roller 24 is driven to rotate, driving the material to completely enter the device along the transport direction;

[0045] Then, the fan 11 is started, and fresh air is pumped into the exhaust slot 13 through the connecting pipe 12, so that the fresh air is blown into the inner cavity of the working box 1 along the opening of the exhaust slot 13. Then, the water pump 6 is started, and the cooling water in the cooling water supply box 2 is pumped into the transfer pipe 8 through the connecting pipe 1 7, and flows evenly to the surface of the material through the drainage slot 9 to cool it down. At this time, the fresh air from the exhaust slot 13 blows toward the material from the oblique rear side and the oblique front side of the material transportation direction, and cooperates with the water flowing on the surface of the material for auxiliary cooling;

[0046] Then, the telescopic rod 19 is started, and the mounting frame 17 is driven to rotate counterclockwise around the axis of the movable column 16 through the fixed column 18, driving the connecting plate 33 and the adapter column 32 to move downward and rotate counterclockwise around the axis of the movable column 16. At this time, the adapter column 32 drives the limiting cylinder 31, the limiting plate 30, the support column 28 and the spring 27 to rotate synchronously, and the adapter column 32 begins to penetrate into the interior of the limiting cylinder 31, and makes the highest point of the limiting plate 30 higher than the highest point of the outer surface of the spring 27, providing a limiting support for one end of the inclined material. When the support column 28 drives the accommodating cylinder 26 to rotate, the roller 29 rotates and abuts against the bottom of the inner wall of the working box 1 to provide adaptation. When the connecting plate 33 abuts against the limiting cylinder 31, the connecting plate 33 and the limiting plate 30 no longer move relative to each other, but become a whole, and the spring 27 is compressed by the supporting column 28 moving downward;

[0047] Finally, the mounting frame 17 as a whole drives the material to be distributed in an inclined manner with the left side lower and the right side higher. At this time, the water flow on the surface of the material will flow from right to left under the action of gravity, thereby fully covering the surface of the material and maintaining the uniformity of the water cooling effect on the surface of the material. In addition, due to the inclined design, the water flow loss rate at the bottom of the material is greatly reduced, making its water cooling effect closer to that of the other surfaces.

[0048] After cooling is completed, the water in the inner cavity of the working box 1 enters the water supply pipe 5 through the drain pipe 4 and is cooled. Subsequently, the water flows back to the cooling water supply box 2 through the water supply pipe 5, and the telescopic rod 19 is started, and the fixed column 18 and the mounting frame 17 are driven to return to a horizontal state. At this time, the connecting plate 33, the adapter column 32 and the limit plate 30 also rotate accordingly. The connecting plate 33 drives the adapter column 32 to gradually return to its original state, and makes the adapter column 32 move upward relative to the inner wall of the limit cylinder 31, so that the transport roller 24 is higher than the highest point of the limit plate 30 again. After the support 28 and the accommodating cylinder 26 drive the roller 29 to rotate and return to its original state, the spring 27 restores it to its original state, starts the motor 23, and drives the transport roller 24 to rotate, and transports the material out along the transport direction.
