This device is widely used in the production processes of products such as toilet paper, kitchen paper, and wiping paper. The small-roll rewinding paper machine can improve production efficiency, reduce labor costs, and ensure the uniformity and quality of products. When the paper machine is in use, rewinding needs to be carried out at regular intervals for long-term use.

[0003] When rewinding is carried out currently, generally, the paper machine is first stopped, the paper is cut manually by a cutter, etc., then the wound paper roll is removed, a paper core without wound paper is replaced, the cut position of the paper is adhered to the newly replaced paper core, and then winding is carried out. Such an operation is too time-consuming and the efficiency is too low. To solve this technical problem, the utility model proposes an upgraded automatic rewinding device added to a small-roll rewinding paper machine. Summary of the Utility Model

When the winding is completed, the paper is pressed by the fixing mechanism, and then the power mechanism drives the rotating ring to rotate, moving the wound paper core to the lifting mechanism. The paper core cuts the paper under the action of the cutting scissors. When the next unwound paper core moves to the fixing plate, the fixing mechanism drives the paper to adhere to the paper core, so as to continue winding, without the need of manual assistance, to improve efficiency, thus solving the problem that the existing manual method of replacing the paper core is too time-consuming and has too low efficiency.

[0015] In the utility model, by setting components such as a lifting mechanism, when the wound paper core moves to the fixed box, the first telescopic rod drives the top plate to move upward, so that the top plate moves upward from the groove, thereby ejecting the paper core on the rotating plate and making the paper core fall into the storage box for storage, achieving the effect of removing the wound paper core. After long-term use, the opening and closing plate can be opened to take out the wound paper core. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, an upgraded automatic roll-changing device added to a small-roll rewinder includes a housing 1. A storage box 2 is fixedly installed at the lower part of the housing 1. A rotating ring 3 is slidably connected to the upper surface of the storage box 2. A power mechanism 4 is arranged in the middle of the rotating ring 3. The power mechanism 4 includes a first motor 401. The lower surface of the first motor 401 is fixedly installed with a mounting plate 402. The end of the mounting plate 402 is fixedly connected to the storage box 2. The mounting plate 402 is used to fix the first motor 401. The output end of the first motor 401 is fixedly connected with a connecting plate 403. The end of the connecting plate 403 is fixedly connected to the rotating ring 3. By setting the connecting plate 403, the first motor 401 can drive the rotating ring 3 to rotate.

[0024] A plurality of rotating mechanisms 5 are arranged below the rotating ring 3. A paper core 6 is arranged above the rotating mechanism 5. An adhesive is applied to the outer surface of the paper core 6 to stick the paper. The rotating mechanism 5 includes a second motor 501. The outer surface of the second motor 501 is installed at the lower part of the rotating ring 3. The output end of the second motor 501 penetrates through the rotating ring 3 and is fixedly connected with a rotating plate 502. A bonding plate 13 is bonded inside the paper core 6. The inner wall of the bonding plate 13 is slidably connected to the rotating plate 502. The second motor 501 can drive the bonding plate 13 to rotate through the rotating ring 3, thereby driving the paper core 6 to rotate. When the winding is completed, the bonding plate 13 can be torn off.

[0025] The outer surface of the housing 1 is provided with a lifting mechanism 7. The lifting mechanism 7 includes a fixed box 701. The outer surface of the fixed box 701 is fixedly connected to the housing 1. A first telescopic rod 702 is installed inside the fixed box 701. The telescopic end of the first telescopic rod 702 is fixedly connected to a top plate 703. A groove 12 is formed in the inner wall of the rotating ring 3, and the top plate 703 can pass through the groove 12.

[0026] A fixing plate 8 is fixedly installed on the outer surface of the housing 1. A fixing mechanism 9 is arranged inside the fixing plate 8. A cutting scissors 10 is fixedly installed on the inner wall of the fixing plate 8. The fixing mechanism 9 includes a second telescopic rod 901. The second telescopic rod 901 is installed on the outer surface of the fixing plate 8. The output end of the second telescopic rod 901 is fixedly connected to a movable plate 902. The second telescopic rod 901 can drive the movable plate 902 to slide. The outer surface of the movable plate 902 is slidably connected to the fixing plate 8. A round rod for sliding is arranged on the side surface of the movable plate 902. A sliding groove is arranged on the fixing plate 8. One end of the movable plate 902 is provided with a third telescopic rod 903. The telescopic end of the third telescopic rod 903 is fixedly connected to a pressing plate 904. The paper can be clamped by the two pressing plates 904. A opening and closing plate 11 is hinged on the inner wall of the storage box 2.

[0027] It should be noted that during the actual use of the device, multiple paper cores 6 are sleeved on the rotating plate 502. The second motor 501 near the fixing plate 8 drives the rotating plate 502 to rotate. The rotating plate 502 drives the paper core 6 to rotate through the bonding plate 13, so as to wind the paper. When the winding is completed, the second motor 501 stops rotating. The two third telescopic rods 903 extend to drive the two pressing plates 904 to press the paper. Then the first motor 401 drives the rotating ring 3 to rotate, driving all the paper cores 6 to rotate synchronously. The wound paper core 6 moves to the fixed box 701. During the movement, the paper core 6 drives the paper to be pressed against the cutting scissors 10. Under the action of the pressing plate 904 and the cutting scissors 10, the paper is cut. When the next unwound paper core 6 moves to the fixing plate 8, the second telescopic rod 901 extends to drive the pressing plate 904 to move close to the paper core 6. The pressing plate 904 drives the paper to stick to the paper core 6. Then the third telescopic rod 903 drives the pressing plate 904 to move away from the paper. Then the second telescopic rod 901 drives the pressing plate 904 to reset. Then the corresponding second motor 501 drives the corresponding paper core 6 to rotate, so as to continue winding, without the need of manual assistance, to improve the efficiency.

[0028] When the paper core 6 after winding is moved to the fixed box 701, the first telescopic rod 702 drives the top plate 703 to move upward, so that the top plate 703 moves upward from the groove 12, thereby ejecting the paper core 6 on the rotating plate 502, and the paper core 6 falls into the interior of the storage box 2 for easy storage, achieving the effect of removing the wound paper core 6. After long-term use, the opening and closing plate 11 can be opened to take out the wound paper core 6.
