A cooling bed with auxiliary micro-channel aluminum flat tube pore reduction function

Abstract

This utility model discloses a cooling bed with an auxiliary function to reduce porosity in microchannel aluminum flat tubes, relating to the field of microchannel aluminum flat tube production technology. It includes a frame and support legs. The top of the support legs is fixedly connected to the frame, and a conveying roller is rotatably connected to the inner side of the frame. A cleaning mechanism is provided on the side of the conveying roller, and a fixing plate is fixedly connected to one end of the frame. When the conveying roller rotates and conveys the aluminum flat tube, the system drives a reciprocating screw via a motor, causing the cleaning plate and brush on the slider to reciprocate. This design causes relative motion between the brush and the rotating surface of the conveying roller, effectively removing alumina particles adhering to the roller surface. This continuous cleaning mechanism ensures that the surface of the conveying roller always maintains good contact with the bottom of the aluminum flat tube, guaranteeing the uniformity of the cooling process. Uniform cooling facilitates the timely discharge of gas from the bottom of the aluminum flat tube, thereby significantly reducing porosity defects at the bottom of the aluminum flat tube.

Description

Technical Field

[0001] This utility model relates to the field of microchannel aluminum flat tube production technology, and in particular to a cooling bed with the function of reducing the porosity of microchannel aluminum flat tubes. Background Technology

[0002] Microchannel aluminum flat tubes are thin-walled, porous, flat tubular materials made from refined aluminum rods through hot extrusion and surface zinc spraying for corrosion protection. They are mainly used in air conditioning systems for various refrigerants as pipe components that carry new environmentally friendly refrigerants.

[0003] In the production process of microchannel aluminum flat tubes, cooling bed cooling is one of the key steps. However, when the aluminum flat tubes are cooled, they react with oxygen in the air to generate alumina dust. At the same time, the decomposition of extrusion dies or lubricants at high temperatures also produces oxide particles. These dust particles easily accumulate on the surface of the conveyor rollers under the action of electrostatic adsorption and mechanical adhesion, leading to the following problems: the dust layer hinders the direct contact between the bottom of the aluminum flat tube and the roller, reduces the local heat transfer efficiency at the bottom, and affects the cooling uniformity of the bottom of the aluminum flat tube; uneven cooling may cause the gas at the bottom of the aluminum flat tube to not be discharged in time, forming porosity defects. Therefore, a cooling bed with the function of assisting in reducing porosity of microchannel aluminum flat tubes is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a cooling bed with an auxiliary microchannel aluminum flat tube porosity reduction function to solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cooling bed with auxiliary microchannel aluminum flat tube porosity reduction function includes a frame and support legs. The top of the support legs is fixedly connected to the frame, and a conveying roller is rotatably connected to the inner side of the frame. A cleaning mechanism is provided on the side of the conveying roller. A fixing plate is fixedly connected to one end of the frame, and a controller is fixedly connected to one end of the fixing plate.

[0007] Preferably, the cleaning mechanism includes a base plate fixedly connected to the frame, a side plate fixedly connected to the top of the base plate, a reciprocating assembly fixedly connected to one end of the side plate, a cleaning plate fixedly connected to one end of the reciprocating assembly, and the cleaning plate is disposed on one side of the conveying roller. A brush is fixedly connected to one end of the cleaning plate, and the brush is in contact with the conveying roller.

[0008] Preferably, the reciprocating assembly includes a motor fixedly connected to a side plate, a reciprocating lead screw fixedly connected to the end of the motor's main shaft, and the other end of the reciprocating lead screw rotatably connected to another side plate. A slider is rotatably connected to the outside of the reciprocating lead screw, and the slider is fixedly connected to a cleaning plate.

[0009] Preferably, a guide shaft is slidably connected to the inner side of one end of the slider, and the guide shaft is fixedly connected to the side plate.

[0010] Preferably, a support plate is fixedly connected to one end of the fixed plate, and an atomizing nozzle is fixedly connected to the inner side of the support plate, and the atomizing nozzle is connected to a cooling water source.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] A cooling bed with auxiliary microchannel aluminum flat tube porosity reduction function is provided. It consists of a motor, reciprocating screw, slider, cleaning plate, and brushes. When the conveyor roller transports the aluminum flat tube, the system drives the reciprocating screw via the motor, causing the cleaning plate and brushes on the slider to reciprocate. This design creates relative motion between the brushes and the rotating conveyor roller surface, effectively removing alumina particles adhering to the roller surface. This continuous cleaning mechanism ensures that the conveyor roller surface maintains good contact with the bottom of the aluminum flat tube, guaranteeing uniform cooling. Uniform cooling facilitates the timely discharge of gas from the bottom of the aluminum flat tube, thus significantly reducing porosity defects at the bottom of the aluminum flat tube.

[0020] Example

[0021] like Figures 1-3 As shown, a cooling bed with auxiliary microchannel aluminum flat tube porosity reduction function includes a frame 1 and a support leg 2. The top of the support leg 2 is fixedly connected to the frame 1. A conveying roller 3 is rotatably connected to the inner side of the frame 1. The conveying roller 3 is a drive roller with a motor and other drive components inside. It can be powered directly by the motor without the need for an external power source. The arrow on the end face of the conveying roller indicates the rotation direction of the conveying roller 3. A cleaning mechanism is provided on the side of the conveying roller 3. A fixing plate 4 is fixedly connected to one end of the frame 1. A controller 5 is fixedly connected to one end of the fixing plate 4. The controller 5 integrates a PLC control system, which coordinates and controls the running speed of the conveying roller 3 and the action sequence of the cleaning mechanism through a preset program to ensure the stability and reliability of their coordinated operation.

[0022] As a further improvement to this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the cleaning mechanism includes a base plate 8 fixedly connected to the frame 1. A side plate 9 is fixedly connected to the top of the base plate 8. A reciprocating assembly is fixedly connected to one end of the side plate 9. A cleaning plate 14 is fixedly connected to one end of the reciprocating assembly. The cleaning plate 14 is disposed on one side of the conveyor roller 3. A brush bristle 15 is fixedly connected to one end of the cleaning plate 14. The brush bristle 15 is in contact with the conveyor roller 3. The cleaning plate 14 is arc-shaped. The brush bristle 15 is made of nylon, which makes the brush bristle 15 highly wear-resistant, has a long service life, and can withstand temperatures up to 120-150℃. At the same time, it has good flexibility and is not easy to scratch the surface of the conveyor roller 3.

[0023] When the conveyor roller 3 rotates and conveys the aluminum flat tube, the bristles 15 move relative to the surface of the rotating conveyor roller 3, effectively removing alumina particles adhering to the roller surface. This continuous cleaning mechanism ensures that the surface of the conveyor roller always maintains good contact with the bottom of the aluminum flat tube, guaranteeing the uniformity of the cooling process. Uniform cooling facilitates the timely discharge of gas from the bottom of the aluminum flat tube, thereby significantly reducing porosity defects at the bottom of the aluminum flat tube.

[0024] As a further improvement to this utility model, such as Figure 2 and Figure 3 As shown, the reciprocating assembly includes a motor 10 fixedly connected to a side plate 9. A reciprocating lead screw 11 is fixedly connected to the end of the main shaft of the motor 10, and the other end of the reciprocating lead screw 11 is rotatably connected to another side plate 9. A slider 12 is rotatably connected to the outside of the reciprocating lead screw 11, and the slider 12 is fixedly connected to a cleaning plate 14. The motor 10 is a servo motor. When the conveying roller 3 transports the aluminum flat tube, the control cabinet 5 controls the motor 10 to rotate the reciprocating lead screw 11 inside the slider 12 through a pre-set PLC program. Under the interaction of the reciprocating lead screw 11 and the slider 12, the slider 12 can move back and forth along the axial direction of the reciprocating lead screw 11, so that the slider 12 carries the brush bristles 15 through the cleaning plate 14 and there is an axial relative movement between it and the conveying roller 3. At the same time, under the rotation of the conveying roller 3, the conveying roller 3 can also move circumferentially with the brush bristles 15. Through the cooperation of multiple movement modes, the efficiency of the brush bristles 15 in cleaning the alumina powder on the surface of the conveying roller 3 can be improved.

[0025] As a further improvement to this utility model, such as Figure 2 As shown, a guide shaft 13 is slidably connected to the inner side of one end of the slider 12, and the guide shaft 13 is fixedly connected to the side plate 9. The guide shaft 13 plays the role of guiding and limiting the slider 12.

[0026] As a further improvement to this utility model, such as Figure 1As shown, a support plate 6 is fixedly connected to one end of the fixed plate 4, and an atomizing nozzle 7 is fixedly connected to the inner side of the support plate 6. The atomizing nozzle 7 is connected to a cooling water source, and the external cooling water source sprays cooling water onto the surface of the aluminum flat tube through the atomizing nozzle 7, thereby achieving cooling of the aluminum flat tube.
