[0022] Refer to Figures 1 - 4 , a copper-aluminum-copper double-sided composite belt rolling mill, comprising:

[0023] The main body housing 1 is hollowed out on both sides, and a C-shaped fixing frame 2 is fixedly connected to the inner wall of the main body housing 1. Raw material belt feeding and cleaning linkage components are provided on the inner top, inner bottom and side wall of the C-shaped fixing frame 2;

[0024] A U-shaped connecting frame 3 is fixedly connected to the inner wall of the main body housing 1. Two rolling rollers 4 are rotatably connected in the U-shaped connecting frame 3. A driving port 5 is fixedly connected to one side of the U-shaped connecting frame 3. Two output ends of the driving port 5 are coaxially fixedly connected to the two rolling rollers 4 respectively;

[0025] Specifically, the driving port 5 can drive the rolling rollers 4 to rotate. The rotation directions of the two rolling rollers 4 are opposite. The rolling rollers 4 can roll the strip material to form a composite belt;

[0026] The raw material belt feeding and cleaning linkage component includes a clamping frame 6, a guiding roller 7 and a synchronous pulley 8. The three clamping frames 6 are respectively fixedly connected to the inner top, inner bottom and side wall of the C-shaped fixing frame 2. The guiding roller 7 is rotatably connected in the clamping frame 6. The synchronous pulley 8 is rotatably connected to one side of the clamping frame 6. The rotating shaft of the synchronous pulley 8 penetrates through the clamping frame 6 and is coaxially fixedly connected to the guiding roller 7. Two telescopic rods 9 are fixedly connected to the inner top of the clamping frame 6. A buffer spring 10 is sleeved outside the telescopic rod 9. The top of the buffer spring 10 is fixedly connected to the clamping frame 6. The output ends of the two telescopic rods 9 are fixedly connected to a cleaning frame 11. A grinding roller 12 is rotatably connected in the cleaning frame 11. A grinding adhesive cloth is embedded outside the grinding roller 12. The bottom of the buffer spring 10 abuts against the cleaning frame 11;

[0027] Specifically, the grinding roller 12 and the grinding adhesive cloth cooperate to mechanically remove the oxide layer on the strip material. When the strip material passes through the guide roller 7, the buffer spring 10 on the clamping bracket 6 and the telescopic rod 14 cooperate to make the grinding roller 12 on the cleaning bracket 11 fit with the strip material, which can prevent the strip material from being displaced during movement to a certain extent;

[0028] Through slots are provided on both sides of the clamping bracket 6. The rotating shaft of the grinding roller 12 passes through the cleaning bracket 11 and is slidably connected in the through slots. A matching pulley 13 is coaxially and fixedly connected to one side of the rotating shaft of the grinding roller 12. A connecting block is fixedly connected to one side of the clamping bracket 6. Two matching telescopic rods 14 are fixedly connected to one side of the connecting block. A return spring 15 is sleeved outside the matching telescopic rods 14. The output ends of the two matching telescopic rods 14 are fixedly connected to a rotating seat 16. Both ends of the return spring 15 are abutted against the rotating seat 16 and the connecting block respectively. A connecting pulley 17 is rotatably connected in the rotating seat 16. A transmission belt is sleeved between the synchronous pulley 8, the matching pulley 13 and the connecting pulley 17;

[0029] Specifically, when the strip material passes through the guide roller 7, the guide roller 7 will rotate, and the synchronous pulley 8 coaxially and fixedly connected to the guide roller 7 will rotate. Through the transmission of the transmission belt, the connecting pulley 17 can rotate. When the connecting pulley 17 rotates, the grinding roller 12 coaxially and fixedly connected to the connecting pulley 17 will rotate. It should be noted that the size of the synchronous pulley 8 is larger than that of the connecting pulley 17, so the rotation speed of the grinding roller 12 is significantly higher than that of the guide roller 7. The grinding roller 12 can remove the oxide layer of the strip material. At the same time, when the strip material is thicker due to the existence of the oxide layer, the buffer spring 10 will contract to a certain extent. At this time, the position of the grinding roller 12 will rise relatively. At this time, the matching pulley 13 will move towards the connecting block side, and the return spring 15 and the matching telescopic rods 14 will contract to a certain extent. The purpose of setting the matching pulley 13 is to ensure the tightness of the transmission belt and ensure the normal transmission efficiency of the transmission belt.

[0030] The functional principle of the present utility model can be described through the following operation mode:

[0031] During actual use, two groups of copper strip materials can be passed through the two raw material strip feeding and cleaning linkage components in the C-shaped fixing frame 2, and the aluminum strip material can be passed through the raw material strip feeding and cleaning linkage components on the inner wall of the main body housing 1. The three strip materials finally pass through the two rolling rollers 4. The driving port 5 can drive the rolling rollers 4 to rotate. The rotation directions of the two rolling rollers 4 are opposite. The rolling rollers 4 can roll the strip materials to form a composite strip;

[0032] The grinding roller 12 and the grinding adhesive cloth cooperate to mechanically remove the oxide layer on the strip material. When the strip material passes through the guide roller 7, the buffer spring 10 on the clamping bracket 6 and the telescopic rod 14 cooperate to make the grinding roller 12 on the cleaning bracket 11 fit with the strip material, which can prevent the strip material from being displaced during movement to a certain extent;

[0033] When the strip material passes through the guide roller 7, the guide roller 7 will rotate, and the synchronous pulley 8 fixedly connected coaxially with the guide roller 7 will rotate. Through the transmission of the transmission belt, the connecting pulley 17 can rotate. When the connecting pulley 17 rotates, the grinding roller 12 fixedly connected coaxially with the connecting pulley 17 will rotate. It should be noted that the size of the synchronous pulley 8 is larger than that of the connecting pulley 17, so the rotation speed of the grinding roller 12 is significantly greater than that of the guide roller 7, and the grinding roller 12 can remove the oxide layer of the strip material. At the same time, when the strip material is thicker due to the existence of the oxide layer, the buffer spring 10 will contract to a certain extent. At this time, the position of the grinding roller 12 will rise relatively. At this time, the matching pulley 13 will move towards the connecting block side, and the reset spring 15 and the matching telescopic rod 14 will contract to a certain extent. The purpose of setting the matching pulley 13 is to ensure the tightness of the transmission belt and ensure the normal transmission efficiency of the transmission belt.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
