Each unwinding station 22 is a C-shaped slot 221 with its opening facing the right, and a sealing cylinder 23 is fixed on one side of the opening end of the C-shaped slot 221; the raw material roll feeding mechanism 3 includes a frame 31 and two symmetrically arranged vertical guide rails 32, and a slide block 33 is slidably connected to the vertical guide rails 32. A horizontal guide is fixed on the upper surface of the slide block 33. A slider 35 is slidably connected to a horizontal guide rail 34. An air expansion shaft seat 36 is fixed on the upper surface of the slider 35, and a "V"-shaped limiting groove 361 is opened at the upper end of the air expansion shaft seat 36. A push reduction motor 37 is fixed on the side of the slide block 33. The output shaft of the push reduction motor 37 is connected to a horizontal push lead screw 38. The horizontal push lead screw 38 is threadedly connected to the slider 35. A chain 39 and several sprockets 310 are arranged around the frame 31. The chain 39 is wrapped around the outer circumference of the sprockets 310. One of the sprockets 310 is driven by a lifting reduction motor 311. The middle part of the chain 39 is fixedly connected to the upper surface of the slide block 33.

[0022] The tilting arm 21 is rotatably connected to the unwinding frame 2 via a rotating shaft 211, which is driven to rotate by a servo motor.

[0023] The vertical guide rail 32 consists of two symmetrically arranged linear guide rails made of 45 steel with a surface hardening treatment.

[0024] The "V"-shaped limiting groove 361 of the air expansion shaft seat 36 has an angle of 90° and a groove depth of 50mm, which is suitable for the shape of the roll material central shaft.

[0025] After the piston rod of the sealing cylinder 23 extends, it fits against the open end of the C-shaped slot 221.

[0026] Example Workflow

[0027] 1. Low position positioning: Start the lifting reduction motor 311 to drive the chain 39 to descend, which will drive the slide 33 to the lowest position (500mm from the ground) along the vertical guide rail 32.

[0028] 2. Material preparation: The raw material roll (diameter Φ800mm, width 1200mm) is placed on the ground and rolled to the "V" shaped limiting groove of the air expansion shaft seat 36;

[0029] 3. Vertical lifting: Start the lifting reduction motor 311 to drive the chain 39 to rise, so that the middle shaft of the raw material roll is clamped into the limiting groove, and then the slide 33 and the roll are lifted to the high position and the C-shaped clamping groove 221 of the turnover arm 21 is horizontally aligned, and the height difference is less than or equal to 2mm;

[0030] 4. Push feeding: Start the push reduction motor 37 to drive the horizontal push lead screw 38, and the gas expansion shaft seat 36 moves to the C-shaped clamping groove 221, so that the middle shaft of the raw material roll is completely pushed into the C-shaped clamping groove 221, and the transfer of the raw material roll is completed;

[0031] 5. Blocking and fixing: The blocking cylinder 23 piston rod is extended to block the opening of the C-shaped clamping groove 221 to prevent the raw material roll from falling out;

[0032] 6. Turnover and unwinding: The turnover arm 21 is turned 180° to transfer the roll to the unwinding position, and the feeding is completed.

[0033] After adopting the above technical scheme, the following technical effects can be achieved:

[0034] 1. Automatic feeding: The lifting reduction motor drives the chain to vertically lift the slide, and the push reduction motor drives the horizontal push lead screw to push the slide, so that the raw material roll is automatically transferred from the low feeding position to the high unwinding position, without manual lifting, reducing the safety hazard.

[0035] 2. Double-station high-efficiency unwinding: The C-shaped clamping groove is arranged at both ends of the turnover arm, the turnover arm is turned 180° after feeding, two unwinding stations can be used alternately, and the unwinding efficiency is improved (the time for single roll feeding is shortened to 2-3 minutes).

[0036] 3. Precise positioning: The "V"-shaped limiting groove of the gas expansion shaft seat is matched with the shape of the roll middle shaft, and the precise transmission of the horizontal push lead screw ensures that the roll middle shaft is coaxially aligned with the C-shaped clamping groove, avoiding the winding jam caused by deviation.

[0037] 4. Safety protection: The opening end of the C-shaped clamping groove is blocked by the blocking cylinder to prevent the roll from falling out accidentally during the turnover or unwinding process, and the safety of the equipment operation is improved.
