The circular rod 66 is arranged at the top of the sleeve 65. The sleeve 65 penetrates the positioning support 64.

[0049] The circular rod 66 extends outside the positioning support 64. A rectangular insertion rod 67 is integrally formed at one end of the circular rod 66. Rectangular insertion grooves 68 are arranged at both ends of the paper tube 48. The rectangular insertion rod 67 is matched with the rectangular insertion grooves 68. Two vertical plates 69 are fixedly connected to the top of the bottom plate 1. The screw directions of the two ends of the bidirectional threaded rod 62 are opposite. The bidirectional threaded rod 62 can drive the two bottom blocks 61 to move towards or away from each other. After the rectangular insertion rod 67 is inserted into the rectangular insertion grooves 68, the paper tube 48 can be fixed.

[0050] The second gear 691 is fixedly connected outside the sleeve 65, the third gear 692 is fixedly connected outside the circular rod 66, the second gear 691 is engaged with the third gear 692, the second gear 691 drives the third gear 692 to rotate after rotating, so that the circular rod 66 is driven, one of the vertical plates 69 is fixedly connected with the third motor 693, the third motor 693 is fixedly connected with one end of the square rod 694 through an output shaft, the two positioning supports 64 are arranged between the two vertical plates 69, the square rod 694 is rotatably connected between the two vertical plates 69, the square rod 694 sequentially penetrates the two sleeves 65, the third motor 693 drives the square rod 694 to rotate after working, and the sleeve 65 can move flexibly outside the square rod 694, the fixed support 7 is fixedly connected to the top of the bottom plate 1, the fixed support 7 is arranged on one side of the base frame 5, and the guide roller 8 is rotatably connected to the inner side of the fixed support 7.

[0051] In actual operation, when the device is used, first, the device is powered on, and the heat-sensitive paper cylinder 48 wound with the heat-sensitive paper to be processed is placed and stored on the top of the second positioning frame 47. When placing, the clamping plate 491 on the second positioning frame 47 clamps and fixes the two ends of the heat-sensitive paper cylinder 48 to improve the stability. After the first motor 481 works, the first gear 482 is driven to rotate, the first gear 482 drives the gear ring 499 to rotate clockwise, the gear ring 499 drives the annular rotating plate 493 to rotate, the annular rotating plate 493 drives the positioning plate 494 to rotate, and the positioning plate 494 drives the annular support plate 3 to rotate;

[0052] Under normal conditions, the spring 484 has elastic thrust on the rectangular plate 483, so that the first positioning frame 46 and the second positioning frame 47 are located on the inner side of the annular support plate 3, so that the first positioning frame 46 and the second positioning frame 47 do not extend out of the annular support plate 3, thereby avoiding the case that the device occupies a large volume. When paper feeding is needed, the above operation is repeated to move the paper cylinder 48 to be fed to the direction of the two positioning supports 64. When the arc-shaped plate 44 on one side of the paper cylinder 48 moves to the range that the pushing plate 496 can touch, the electric push rod 495 works and pushes the pushing plate 496. After the pushing plate 496 moves into the arc-shaped groove 498 of the arc-shaped plate 44, the pushing plate 496 can slide in the arc-shaped groove 498. Therefore, while the arc-shaped plate 44 rotates with the annular support plate 3, the electric push rod 495 can continuously work to achieve the purpose of horizontally pushing the arc-shaped plate 44 by the pushing plate 496. The arc-shaped plate 44 drives the extension plate 43 to move, the extension plate 43 drives the movable block 42 to move, the movable block 42 drives the connecting rod 45 to move, and the connecting rod 45 drives the first positioning frame 46 and the second positioning frame 47 to move;

[0053] Through the above operation, the second positioning frame 47 top of the paper tube 48 to be loaded both ends of the rectangular slot 68 is in the position of the rectangular insertion rod 67 can be inserted, the second motor 63 works and drives the double -sided screw rod 62 rotation, the double -sided screw rod 62 drives two bottom blocks 61 move towards each other, the bottom block 61 moves and drives the positioning support 64 to move, the positioning support 64 drives the round rod 66 to rotate, the rectangular insertion rod 67 at one end of the round rod 66 is inserted into the rectangular slot 68, and the control ring support plate 3 continues to rotate, then at this time, because the paper tube 48 has been fixed by the rectangular insertion rod 67, in the process of the second positioning frame 47 continuing to move down, the two clamps 491 on the top of the second positioning frame 47 will be opened, when the paper tube 48 moves out between the two clamps 491, the electric push rod 495 is retracted, and through the above connection, the second positioning frame 47 after loading moves back to the inside of the ring support plate 3 under the push of the spring 484, so as to facilitate the development of the next loading operation.

[0054] Similarly, when the thermal paper outside the paper tube 48 is pulled out, or the paper tube 48 wound with processed thermal paper needs to be removed due to different processing scenes, the above similar steps can be repeated, the electric push rod 495 is controlled to work to push the selected first positioning frame 46 out, after the first positioning frame 46 is pushed out, as it continues to move down, the two clamps 491 at the bottom of the first positioning frame 46 will be opened and contacted with the two ends of the paper tube 48 to be removed, until the ends of the paper tube 48 enter between the two clamps 491 and can be well clamped and fixed, the double -sided screw rod 62 is controlled to rotate, so that the two rectangular insertion rods 67 move away from the paper tube 48, since the paper tube 48 has been fixed inside the clamp 491, the paper tube 48 will not fall off, then the electric push rod 495 is retracted, so the paper tube 48 will follow the first positioning frame 46 into the inside of the ring support plate 3, so as to successfully complete the unloading operation, the whole loading and unloading operation is simple and convenient, more labor-saving and higher efficiency.

[0055] Finally, the third motor 693 in the device works to drive the square rod 694 to rotate, the square rod 694 drives the sleeve 65 to rotate, the sleeve 65 drives the second gear 691 to rotate, the second gear 691 drives the third gear 692 to rotate, the third gear 692 drives the round rod 66 to rotate, the round rod 66 drives the rectangular insertion rod 67 to rotate, so that after the rectangular insertion rod 67 is inserted into the paper tube 48, the purpose of driving the paper tube 48 to rotate can be achieved, so as to facilitate the smooth development of the winding or paper feeding operation of the paper tube 48 during processing.
