The first driving structure The structure is installed on the frame 100 and is used to drive the turntable 410 to rotate. The turntable 410 is evenly spaced along the circumference and is provided with a plurality of winding air shafts 420 and a second driving structure for driving the winding air shafts 420 to rotate. The winding air shafts 420 are sleeved with a sleeve 430 for winding the paper 700; the clamping mechanism 500 is connected to the frame 100, and the clamping mechanism 500 is arranged corresponding to the position of the turntable 410; the cutting mechanism 600 is connected to the frame 100, and the cutting mechanism 600 is arranged corresponding to the position of the turntable 410.

[0039] Specifically, the high-efficiency rewinding machine provided by the embodiment of the utility model is provided with a rewinding mechanism 400, a pressing mechanism 500 and a cutting mechanism 600 on the frame 100. The rewinding mechanism 400 is provided with a rewinding air shaft 420 on the turntable 410, and the rewinding air shaft 420 is driven by the second driving structure to drive the sleeve 430 to rotate, so as to rewind the paper 700. After the rewinding is completed, the paper 700 is automatically cut by the cutting mechanism 600, and the end of the paper 700 to be rewound is pressed on the next sleeve by the pressing mechanism 500. On the cylinder 430, the next winding air shaft 420 is automatically wound, and the turntable 410 is driven to rotate by the first driving structure to drive the next winding air shaft 420 to the position of the cutting mechanism 600. The whole process is carried out automatically. The staff only needs to remove the sleeve 430 that has been rewound while the winding air shaft 420 is winding, and add the sleeve 430 to the remaining winding air shaft 420 without the sleeve 430. There is no need to stop the working state of the rewinding machine, which greatly improves the rewinding efficiency and saves time.

[0040] Further, see Figure 4 According to some embodiments of the utility model, the first driving structure includes a first motor 440, which is installed on the frame 100. The output shaft of the first motor 440 extends in the horizontal direction. The output shaft of the first motor 440 extends out of the frame 100 and is fixedly connected to the middle part of the turntable 410, so that the turntable 410 is driven to rotate by the first motor 440 to realize the switching of the winding inflatable shaft 420.

[0041] Furthermore, in the embodiment of the present utility model, the first driving structure may also be other structural forms, which will not be described in detail here.

[0042] Further, see Figure 4 According to some embodiments of the utility model, the second driving structure includes a second motor 450, which is installed on a side of the turntable 410 close to the frame 100. The output shaft of the second motor 450 is parallel to the output shaft of the first motor 440. The output shaft of the second motor 450 passes through the turntable 410 and fixedly receives the winding air shaft 420. The winding air shaft 420 is coaxially arranged with the output shaft of the second motor 450, so that the winding air shaft 420 is driven to rotate by the second motor 450 to realize the winding of the paper 700.

[0043] Furthermore, in the embodiment of the present utility model, the second driving structure may also be other structural forms, which will not be described in detail here.

[0044] Further, see Figure 2According to some embodiments of the utility model, the clamping mechanism 500 includes a first connecting seat 510, a first rotating shaft 520, a connecting rod 530 and a pressure roller 540. The first connecting seat 510 is fixedly connected to the frame 100. The first rotating shaft 520 is parallel to the output shaft of the first motor 440. One end of the first rotating shaft 520 is connected to the side of the first connecting seat 510 away from the frame 100. One end of the connecting rod 530 is rotatably connected to the first rotating shaft 520. The other end of the connecting rod 530 is fixedly connected to the pressure roller 540. The pressure roller 540 is parallel to the first rotating shaft 520. The position of the pressure roller 540 corresponds to the position of the sleeve 430 located at the top. The first rotating shaft 520 is sleeved with a torsion spring. One end of the torsion spring is fixedly connected to the first rotating shaft 520, and the other end of the torsion spring is fixedly connected to the first rotating shaft 520. The torsion spring can force the first rotating shaft 520 to rotate.

[0045] It can be understood that the clamping mechanism 500 corresponds to the position of the winding air shaft 420 located at the top of the turntable 410. When the top winding air shaft 420 is winding the paper 700, the first rotating shaft 520 is forced to rotate through the torsion spring so that the pressure roller 540 can press the outside of the paper roll, so that the paper 700 is wound more tightly, thereby improving the rewinding quality. When the winding of the topmost winding air shaft 420 is completed, the turntable 410 is rotated to adjust the position of the winding air shaft 420, so that the winding winding air shaft 420 that has completed winding is moved to the position of the cutting mechanism 600. At this time, since the pressure roller 540 has been pressing the outer side of the paper 700, the pressure roller 540 can press the end of the paper roll on the next winding air shaft 420. After the cutting mechanism 600 cuts the paper 700, the end of the paper 700 is still pressed by the pressure roller 540 on the next winding air shaft 420, so that the next paper roll can be directly wound, thereby improving work efficiency.

[0046] Furthermore, according to some embodiments of the present invention, the pressure roller 540 is made of plastic material, and a rubber layer is provided on the surface of the pressure roller 540 .

[0047] It is understandable that the pressure roller 540 is made of plastic material, has a certain degree of deformability, can fit more closely, thereby increasing friction, and can protect the paper 700 at the same time. The provision of a rubber layer can further increase friction.

[0048] Further, see Figure 5 and Figure 6According to some embodiments of the present invention, the cutting mechanism 600 includes a second mounting seat 610, a first electric push rod 620, a moving seat 630, a cutter 640 and a second electric push rod 650. The second mounting seat 610 is fixed to the frame 100. The second mounting seat 610 is provided with an inner cavity 611 with an opening facing downward. The first electric push rod 620 is installed on the outer wall of the second mounting seat 610. The first electric push rod 620 is provided with a first push rod 621, and the first push rod 621 is parallel to The output shaft of the first motor 440, the first push rod 621 extends into the inner cavity 611 and is fixedly connected to the movable seat 630, the cutter 640 is installed on the movable seat 630 and extends downward, the second electric push rod 650 is installed on the movable seat 630, the second electric push rod 650 is connected to the cutter 640 and is used to drive the cutter 640 to move in the vertical direction, and a cutting platform 460 is arranged between two adjacent winding air shafts 420, and the cutter 640 can cooperate with the cutting platform 460 to cut the paper 700.

[0049] It can be understood that the position of the cutter 640 in the horizontal direction is adjusted by the first electric push rod 620 to adapt to different cutting positions of the paper 700, and the cutter 640 is driven by the second electric push rod 650 to cut the paper 700. The cooperation between the cutter 640 and the cutting platform 460 can make the cutting smoother.

[0050] Further, see Figure 5 and Figure 6 According to some embodiments of the utility model, the movable seat 630 is provided with a cavity 631 with an opening facing downward, and a guide plate 632 is provided on the inner wall of the cavity 631. The guide plate 632 is provided with a through hole extending in the vertical direction. One end of the cutter 640 is penetrated in the through hole and provided with an abutment block 641. The end of the abutment block 641 is provided with a first inclined surface facing upward. The outer peripheral wall of the cutter 640 is provided with a connecting plate 642, and the connecting plate 642 is located below the guide plate 632. The cutter 640 is sleeved with a telescopic spring 643, one end of the telescopic spring 643 is fixedly connected to the guide plate 632, and the other end is fixedly connected to the connecting plate 642. The second electric push rod 650 is installed on the side wall of the movable seat 630, and the second electric push rod 650 is provided with a second push rod 651, which extends into the cavity 631 and is provided with a push block 652. The end of the push block 652 is provided with a second inclined surface facing downward, and the first inclined surface can cooperate with the second inclined surface.

[0051] It can be understood that the second electric push rod 650 drives the push block 652 to move so that the second inclined surface cooperates with the first inclined surface of the abutment block 641, so that the push block 652 can push the abutment block 641 to move downward, thereby driving the cutter 640 to move downward to cut the paper 700. After the cutting is completed, the second electric push rod 650 drives the push block 652 to reset, and the cutter 640 is reset by the elastic force of the telescopic spring 643.

[0052] Further, see Figure 5 and Figure 6 According to some embodiments of the utility model, a first slide groove 612 is provided on the top wall of the inner cavity 611, and the first slide groove 612 extends along the axial direction of the first push rod 621. A sliding seat 660 is provided on the top wall of the movable seat 630, and the sliding seat 660 is slidably connected to the first slide groove 612, so that the movement of the cutter 640 in the horizontal direction is smoother.

[0053] Further, see Figure 7 According to some embodiments of the utility model, the guide mechanism includes two guide wheel groups 310 and a tension adjustment structure. The guide wheel groups 310 are rotatably connected to the frame 100. The guide wheel groups 310 are all made of rubber material. The tension adjustment structure is connected to the frame 100 and is located between the two guide wheel groups 310. The tension adjustment structure is used to adjust the tension of the paper 700.

[0054] Further, see Figure 7 According to some embodiments of the utility model, the tension adjustment structure includes a movable roller 320 and a fixed roller 330, which are arranged in parallel and spaced apart. The fixed roller 330 is fixedly installed on the frame 100, and the frame 100 is provided with a third driving structure, which is connected to the movable roller 320 and drives the movable roller 320 to move up and down.

[0055] It can be understood that the paper 700 passes through the guide wheel group 310, the movable roller 320 and the fixed roller 330 in sequence, and the tension of the paper 700 is adjusted by adjusting the upper and lower positions of the fixed roller 330, thereby improving the quality of winding.

[0056] Further, see Figure 7 According to some embodiments of the utility model, the third driving structure includes a third electric push rod 340, and the third electric push rod 340 is provided with a third push rod 341. The end of the third push rod 341 is connected to the movable roller 320 through the second connecting seat 350, thereby driving the movable roller 320 to move up and down to adjust the tension of the paper 700.

[0057] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
