Description

Technical Field

[0001] This utility model relates to the field of special aluminum material production technology, and in particular to a winding device for mirror aluminum strip. Background Technology

[0002] Mirror aluminum refers to aluminum sheets that have been processed through rolling, polishing, and other methods to achieve a mirror-like surface. Generally, mirror aluminum in foreign countries is produced by rolling into coils and sheets. Mirror aluminum has a wide range of applications, including lighting fixtures, solar thermal reflectors, exterior wall decoration, and product casings, which are reflective and aesthetically pleasing.

[0003] To prevent damage to aluminum strip due to excessive stretching during the winding process, a Chinese utility model patent technology for an aluminum strip winding machine (publication number: CN206763633U) has been disclosed. This technology discloses an aluminum strip winding machine including a conveying device, a bending device, a winding device, and a drive motor. This technology makes the aluminum material fit more closely to the roll, reduces the load on the tension roller, and ensures that the aluminum strip is subjected to more uniform force during the winding process. It is also wound evenly and tightly on the roll, resulting in greater friction between the layers of the aluminum strip and preventing slippage between the layers.

[0004] The above technology uses bending rollers to transition aluminum strip, thereby preventing damage to the aluminum strip caused by excessive stretching. However, when the mirror aluminum strip is wound, repeated bending can easily damage the mirror aluminum strip. At the same time, if the aluminum strip folds during the winding process, it will cause damage to the mirror aluminum material coil. Utility Model Content

At the same time, the winding device is subjected to the appropriate traction of the counterweight box 41 at the end of the traction rope 42 and the counterweight inside the box, which can ensure that the mirror aluminum strip is fully extended. After the position is corrected by the straightening device 1 and the appropriate counterweight is selected to achieve traction, the smooth winding of the mirror aluminum strip can be guaranteed.

[0023] The counterweight device 4 includes a fixed base 43, on which a guide pulley 44 is provided. The traction rope 42 passes around the guide pulley 44 and is fixed to the counterweight box 41 to ensure stable operation of the device.

[0024] The traction ropes 42 are fixed to both sides of the counterweight box 41 to ensure the force balance and stability of the winding device 2, and at the same time to prevent the counterweight box 41 from tipping over.

[0025] The side of the straightening frame 11 is provided with adjustment holes 5 corresponding to the shaft of the movable roller 13. A fixing knob is provided on the shaft of the movable roller 13, which can adjust the longitudinal position of the movable roller 13 according to the thickness of the mirror aluminum strip to be wound, thereby adjusting the appropriate gap between the fixed roller 12 and the movable roller 13 to adapt to mirror aluminum strips of different thicknesses and ensure the flatness of the strip.

[0026] A scale plate 51 is provided on the corresponding straightening frame 11 of the adjustment hole 5 to facilitate the operator to make precise adjustments to the movable roller 13. Example

[0027] A tension-adaptive winding device for mirror-finish aluminum strip includes a straightening device 1 and a winding device 2. The straightening device 1 includes a straightening frame 11, on which a fixed roller 12 and a movable roller 13 are mounted. The straightening device 1 is fixed to a slide rail 3 and is used to correct the position of the mirror-finish aluminum strip to be wound upon entering the device, preventing damage to the strip due to misalignment. The winding device 2 is slidably mounted on the slide rail 3 and includes a winding frame 21 and a winding clamp roller 22. A drive motor is mounted on the winding frame 21, which is the power source for winding the strip. The drive motor drives the winding clamp roller 22 to rotate, thereby winding the strip. The slide rail 3 is equipped with a counterweight device 4 at its end. The counterweight device 4 includes a counterweight box 41 and a traction rope 42. The counterweight box 41 is connected to the winding frame 21 through the traction rope 42. Through the cooperation of the straightening device 1 and the winding device 2, the mirror aluminum strip to be wound is fed to the winding roller of the winding device 2 by the straightening device 1.

Bolts 7 are fixed to the side of the cleaning frame 61 at the corresponding positions on the slide rail 3. The surface of the mirror aluminum strip entering the device is cleaned by the air blowing of the cleaning device 6 to prevent impurities from mixing into the mirror aluminum material after winding. The simultaneous blowing from the upper and lower sides can ensure the cleanliness of the upper and lower sides of the strip and also ensure the stress balance of the strip.

[0029] Working principle

[0030] When winding mirror aluminum strip, firstly, the end of the mirror aluminum strip is slowly and manually passed through the gap between the fixed roller 12 and the movable roller 13 of the straightening device 1, and the cleaning device 6, and then fixed on the winding roller of the winding device 2. Then, the movable roller 13 is adjusted in sequence to ensure that the gap between the fixed roller 12 and the movable roller 13 is appropriate for the corresponding strip thickness. The cleaning device is fixed by rotating the fixing screw 7. And according to the tensile strength of the strip to be wound, a suitable counterweight is selected and placed in the counterweight box 41. Finally, the drive electrical works and the external fan is turned on to supply air to the cleaning device 6 to clean the surface of the strip and wind it up.
