Description

Technical Field

[0001] The utility model belongs to the technical field of copper foil slitting machines, and in particular relates to a winding and pressing roller mechanism of a copper foil slitting machine. Background Art

[0002] After the copper foil is slit by the slitting knife, it is rolled up. During the rolling process, as the diameter of the copper foil roll increases, more air will enter the inside of each layer of the copper foil, causing the copper foil to be loose or uneven after rolling. The current copper foil slitting machine is very likely to have this situation after rolling more than two kilometers, resulting in the scrapping of the entire roll of copper foil, affecting product quality and wasting manpower and material resources. The existing copper foil slitting machine mechanism: 1. It can only rely on the weight of the roller itself to press the reel; 2. Due to the inconsistent slitting width, the distance of the pressure arm needs to be adjusted frequently. Since the pressure arm and the rotating shaft are key-guided, the pressure arm will often get stuck when moving, greatly affecting efficiency. Utility Model Content

[0026] Further, the first mounting opening 401 is a first U-shaped notch, and a groove wall on one side of the first U-shaped notch is a movable groove wall, so as to facilitate fixing the mounting block 4 on the slider. It is easy to understand that the movable groove wall can be realized by a spring, etc. The second mounting opening 402 includes a second U-shaped notch, and a groove wall on one side of the second U-shaped notch is provided with a latch 403, which vertically penetrates the groove wall of the second U-shaped notch, and the end of the pressure arm 5 is inserted into the second U-shaped notch and tightened by the latch 403.

[0027] A pivot member 404 is provided between the first U-shaped notch and the second U-shaped notch, the extension direction of the pivot member 404 is parallel to the penetration direction of the latch 403, a needle bearing 405 is sleeved on the outer side of the pivot member 404, and the needle bearing 405 is connected to the second U-shaped notch.

[0028] The pivot member 404 passes through the mounting block 4, and a fixing ring 406 is provided at the end of the mounting block 4 adjacent to the pivot member 404.

[0029] In a preferred embodiment, a detachable pressing plate 407 is provided on the top of the second U-shaped notch.

[0030] Continue to view Figure 1 As shown, the rotary drive member includes a cylinder 7 and a rotary arm 8, and the cylinder 7 is connected to the rotary shaft 1 through the rotary arm 8. Preferably, there are four pressing arms 5, and a quick-change mechanism is also provided at one end of the pressing arm 5 to facilitate the rapid replacement of the pressing roller 3.

[0031] There are two ways to work:

[0032] 1. Cylinder clamping method (retain the pressure plate 407 of the mounting block 4):

[0033] According to the width of the copper foil after slitting, select the appropriate pressure roller 3, measure the fixed position of the pressure roller 3, move the pressure arm 5 by hand to drive the slider of the linear guide 2 to move, install the pressure roller 3 on the pressure arm 5 after reaching the position, and adjust the movable groove wall to fix the mounting block 4. The solenoid valve controls the cylinders 7 on both sides at the same time. The cylinder 7 retracts and drives the rotating arm 8 to rotate. The rotating arm 8 is installed on the rotating shaft 1 with bolts, thereby driving the rotating shaft 1 to rotate and the mounting block 4 to rotate. The pressure arm 5 rotates, thereby driving the pressure roller 3 to rotate, which plays a role of pressing. When the copper foil is pressed, the pressure arm 5 stops rotating, and the pressure roller 3 is pressed by the air pressure of the cylinder 7 and the weight of the pressure roller 3.

[0034] 2. Pressing roller deadweight pressing method (remove the pressing plate 407 of the mounting block 4):

[0035] According to the width of the copper foil after slitting, select the appropriate roller 3, measure the fixed position of the roller 3, move the pressure arm 5 by hand to drive the slider of the linear guide 2 to move, install the roller 3 on the pressure arm 5 after reaching the position, and adjust the movable groove wall to fix the mounting block 4. The solenoid valve controls the cylinders 7 on both sides at the same time, and the cylinders retract, driving the rotating arm 8 to rotate. The rotating arm 8 is installed on the rotating shaft 1 with bolts, thereby driving the rotating shaft 1 to rotate and the mounting block 4 to rotate. Due to its own weight, the roller 3 will drive the pressure arm 5 to rotate with the mounting block 4. When the roller 3 presses the copper foil, it stops. As the coil diameter of the copper foil gradually increases, the roller 3 moves upward, so that the roller 3 can complete the compression by its own weight.

[0036] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
