[0020] Embodiment:

[0021] Please refer to Figures 1-3 , a translation uncoiler, including a base 1 and an uncoiler body 2. The uncoiler body 2 is horizontally guided and slid on the top of the base 1. A translation drive mechanism for driving the horizontal movement of the uncoiler body 2 is arranged on the base 1. A reel 3 is horizontally arranged on the uncoiler body 2 along the horizontal sliding direction. It further includes a loading trolley that can be horizontally guided and pushed below the reel 3. Unwinding limiting mechanisms are arranged on both the left and right sides of the reel 3.

[0022] Specifically, the horizontal driving mechanism includes a horizontal driving cylinder 19 fixedly installed on the base 1. The output end of the horizontal driving cylinder 19 is fixedly connected to the bottom of the uncoiler body 2. A plurality of horizontal guide shafts 18 that are in guiding and sliding fit with the uncoiler body 2 are fixedly connected to the base 1. By means of the horizontal driving cylinder 19, it is convenient to horizontally push the uncoiler body 2, so that the uncoiler body 2 can be adjusted horizontally. Through the arrangement of the horizontal guide shafts 18, it is convenient to guide the uncoiler body 2 and increase the stability of the horizontal guidance.

[0023] Specifically, the unwinding limiting mechanism includes a pressure wheel 4, a rotating shaft 6, and an adjusting driving cylinder 8. The adjusting driving cylinder 8 is hinged to the uncoiler body 2. The rotating shaft 6 is rotatably connected to one side of the uncoiler body 2. One end of the rotating shaft 6 is fixedly connected with a mounting strip 5. The pressure wheel 4 is rotatably connected to the end of the mounting strip 5 far from the rotating shaft 6. The other end of the rotating shaft 6 is fixedly installed with a connecting strip 7. The end of the connecting strip 7 far from the rotating shaft 6 is hinged to the output end of the adjusting driving cylinder 8. By the telescopic movement of the adjusting driving cylinder 8, it is convenient to drive the whole rotating shaft 6, connecting strip 7, mounting strip 5, and pressure wheel 4 to rotate and adjust, so that the pressure wheel 4 can be moved away from or close to the side of the reel 3. Since the pressure wheel 4 is rotatably connected to the mounting strip 5, it is convenient to drive the pressure wheel 4 to rotate during unwinding, reducing the wear of the coil caused by the friction with the pressure wheel 4 during unwinding.

[0024] Specifically, the loading trolley includes a coil bracket 10. Lifting frames are arranged on both sides of the bottom of the coil bracket 10. A moving component is arranged at the bottom of the lifting frame. By means of the moving component, it is convenient to drive the whole lifting frame and the coil bracket 10 to move. Through the lifting frame, it is convenient for the coil bracket 10 to lift, and further convenient to align the coil placed on the coil bracket 10 with the reel 3, so as to be conveniently sleeved on the reel 3.

[0025] Specifically, the lifting frame includes two support bars 11 that are rotatably connected in the middle. One end of one of the support bars 11 is rotatably connected to the bottom of the coil bracket 10. A clamping shaft 13 is installed at one end of the other support bar 11. And a lifting driving cylinder 15 is hinged between the other end of this support bar 11 and the bottom of the coil bracket 10. A guiding groove 12 that is adapted to the clamping shaft 13 and is horizontally arranged is opened at the bottom of the coil bracket 10. By the telescopic movement of the lifting driving cylinder 15 and the cooperation of the clamping shaft 13 and the guiding groove 12, the two support bars 11 rotate, so that the coil bracket 10 can be driven to lift.

The output shaft of the moving motor 16 and the connecting shaft 17 can be connected by a sprocket and chain drive, or by a belt and pulley drive. Preferably, a sprocket and chain drive is adopted. Starting the moving motor 16 facilitates driving the connecting shaft 17 to rotate, thereby driving the two pulleys 14 on both sides to rotate. With the cooperation of the other two pulleys 14, the material roll bracket 10 is driven to move horizontally.

[0027] During use, place the coiled material on the loading trolley, then move the coiled material to a height equivalent to that of the reel 3. Then move the loading trolley so that the coiled material is sleeved on the reel 3. Then withdraw the loading trolley from the bottom. Then make the reel 3 tighten the coiled material. Then limit the coiled material from both sides through the unwinding limiting mechanisms on both sides. Then, according to the specific position of the coiled material on the reel 3 and its positional relationship with the subsequent processing equipment, drive the entire uncoiler body 2, reel 3 and coiled material to perform horizontal fine adjustment through the translation drive mechanism, adjust the position of the coiled material relative to the subsequent processing equipment, ensure the fixed position of the uncoiling, and improve the uncoiling accuracy.
