[0020] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] like Figures 1 to 3 As shown, the paper winding device of the embodiment of the present invention includes a frame 1, two positioning plates 21, two chuck assemblies, a cutter 3, a drive mechanism 1 9, a drive mechanism 2 and a drive mechanism 3.

[0022] The two positioning plates 21 are arranged along the length direction of the frame 1 and are respectively connected to the frame 1 for rotation. The two chuck assemblies are arranged along the width direction of the frame 1. The chuck assemblies are used to fix the reel 4. Specifically, the length direction of the frame 1 is defined as the front-to-back direction, and the width direction is defined as the left-to-right direction. The two positioning plates 21 are arranged opposite to each other in the front-to-back direction, and the two chuck assemblies are arranged opposite to each other in the left-to-right direction. The driving mechanism 9 includes a motor, an output end of which is connected to the positioning plate 21 and can drive the positioning plate 21 to rotate.

[0023] like Figure 1 and Figure 2 As shown, the chuck assembly includes a driving member four (not shown in the figure) and two chucks 22. The two chucks 22 are arranged along the length direction of the frame 1 and are rotatably connected to two positioning plates 21 respectively. The chucks 22 can slide along the width direction of the frame 1, and the driving member four can drive the chucks 22 to rotate.

[0024] Specifically, the two chucks 22 in the chuck assembly are arranged opposite to each other in the front-to-back direction. In this embodiment, the chuck 22 can be a six-jaw chuck. By controlling the claws in the chuck 22 to move radially along the chuck 22, the end of the reel 4 can be fixed. The six-jaw chuck is an existing mature technology and will not be elaborated in detail here. It can be understood that in some other embodiments, the chuck 22 can also be a three-jaw chuck, a four-jaw chuck, a five-jaw chuck, etc.

[0025] A second driving mechanism (not shown in the figure) is arranged in the positioning plate 21. The second driving mechanism can be an electric push rod and can be extended and retracted in the front and rear directions. Its retractable end is fixedly connected to the chuck 22. By controlling the extension and retraction of the second driving mechanism, the two chucks 22 facing each other can be brought closer or farther away from each other, thereby facilitating the installation of the two ends of the reel 4 on the two chucks 22 respectively, and completing the positioning and fixation of the reel 4. The fourth driving member is arranged in the positioning plate 21. The fourth driving member can be a motor, and its output end is fixedly connected to the chuck 22. After the reel 4 is fixed by the chuck assembly, the fourth driving member is controlled to operate, which can drive the reel 4 to rotate and reel the paper.

[0026] like Figures 1 to 3 As shown, the cutter 3 is slidably installed in the lower part between the two chuck assemblies, and the driving mechanism 3 can drive the cutter 3 to move up and down, and can drive the two chucks 22 installed on the same positioning plate 21 to approach each other.

[0027] Specifically, a mounting frame 6 is provided at the lower part between the two chuck assemblies, and the mounting frame 6 is connected to the frame 1. The driving mechanism three includes a moving member 51 and a driving member three (not shown in the figure). The moving member 51 is connected to the mounting frame 6 by sliding up and down, and the cutter 3 is fixedly installed on the upper part of the moving member 51. The driving member three can be an electric push rod, and its upper and lower ends are respectively fixedly connected to the moving member 51 and the mounting frame 6. The extension and retraction of the driving member three can drive the moving member 51 and the cutter 3 fixedly installed on the upper part of the moving member 51 to rise and fall.

[0028] The driving mechanism three also includes two connecting components that are opposite to each other in the front-to-back direction, and the two connecting components correspond to the two positioning plates 21 respectively. The connecting components include a push rod 521, a sliding member 1 522 and two sliding members 2 523. The push rod 521 is fixedly installed on the upper part of the movable member 51, and the sliding member 1 522 is connected to the positioning plate 21 by sliding up and down, and is located directly above the push rod 521. The two sliding members 2 523 are respectively connected to the two chucks 22 for rotation, and the sliding member 2 523 is slidingly connected to the positioning plate 21 and can slide in the left and right directions. A connecting rod 524 is provided between the sliding member 2 523 and the sliding member 1 522, and the two ends of the connecting rod 524 are respectively hinged to the sliding member 1 522 and the sliding member 2 523, wherein the driving mechanism two and the driving member four are both installed on the sliding member 2 523 and can move with the sliding member 2 523.

[0029] When the present invention is in use, firstly, the driving mechanism 2 and the chuck 22 are controlled to fix the reel 4 on the left chuck assembly, and then the driving member 4 is controlled to drive the left chuck 22 and the reel 4 to rotate counterclockwise to reel the paper coming from the left. When the reeled paper reaches the set standard, the driving mechanism 1 9 is controlled to drive the positioning plate 21 to rotate 180° counterclockwise to change the positions of the two initial chuck assemblies. At this time, the reel 4 that has reeled the paper will move to the right, and continue to fix a new reel 4 on the left chuck assembly. Next, firstly, glue or double-sided tape is applied to the upper surface of the paper at the position to be cut, and then the driving member 3 is controlled to drive the moving member 51 and the cutter 3 and The push rod 521 moves upward, and since the sliding member 1 522 is located directly above the push rod 521, when the push rod 521 moves upward, it will push the sliding member 1 522 to slide upward, and under the action of the connecting rod 524, it will drive the sliding member 2 523 to slide, and make the two chuck assemblies approach each other. At this time, the cutter 3 will move upward synchronously and gradually approach the paper. When the empty roll 4 and the wound paper roll are close to each other to the point where the cutter 3 can just pass through, the cutter 3 moves upward to cut the paper, and the end of the paper at the cutting position can be respectively adhered to the empty roll 4 and the wound paper roll. Next, continue to control the rotation of the left roll 4, that is, the paper can continue to be wound, and the wound paper roll on the right side can be removed by controlling the driving mechanism 2 and the chuck 22.

[0030] In some embodiments, Figure 1 and Figure 2 As shown, the mounting frame 6 is slidably connected to the frame 1 and can move along the width direction of the frame 1, and a fixing member (not shown in the figure) for fixing the position of the mounting frame 6 is provided on the frame 1. When paper is rolled and cut, the position of the mounting frame 6 in the left and right directions can be adjusted according to the diameter of the paper roll after the rolling is completed, so that the mounting frame 6 is located in the middle position between the empty roll 4 and the rolled paper roll, so that the end of the paper at the cutting position is conveniently bonded to the empty roll 4 and the rolled paper roll respectively.

[0031] In some embodiments, Figure 2 As shown, elastic telescopic rods 7 are provided on the upper and lower sides of the sliding member 522, and the opposite outer ends of the two elastic telescopic rods 7 are fixedly connected to the positioning plate 21, and the opposite inner ends are respectively stopped at the upper and lower sides of the sliding member 522, that is, the upper end of the upper elastic telescopic rod 7 is fixedly connected to the positioning plate 21, and the lower end is fitted and stopped with the sliding member 522, and the lower end of the lower elastic telescopic rod 7 is fixedly connected to the positioning plate 21, and the upper end is fitted and stopped with the sliding member 522. When the top rod 521 pushes the sliding member 522 to move upward, the elastic telescopic rod 7 located on the upper side of the sliding member 522 will be compressed, and when the top rod 521 moves downward to reset, the sliding member 522 will move downward and reset under the elastic pushing of the upper elastic telescopic rod 7.

[0032] In some embodiments, Figure 1 and Figure 2 As shown, the upper end of the cutter 3 is the cutting end, and inclined surfaces 811 are provided on both sides below the cutting end. The inclined surfaces 811 gradually move away from the cutter 3 from top to bottom, that is, the inclined surface 811 on the left side is inclined toward the lower left, and the inclined surface 811 on the right side is inclined toward the lower right. When the cutter 3 moves upward to cut the paper, the inclined surfaces 811 on both sides of the cutter 3 can make the end of the paper at the cutting position better bonded to the empty roll 4 and the wound paper roll respectively.

[0033] In some embodiments, Figure 1 and Figure 2 As shown, movable plates 81 are provided on both sides below the cutting end, the upper end of the movable plate 81 is rotatably connected to the cutter 3, the inclined surface 811 is located on the movable plate 81, and an elastic member (not shown in the figure) is provided between the movable plate 81 and the cutter 3. The elastic member is a spring and can elastically push the movable plate 81 toward the outer side of the cutter 3. When the cutter 3 moves upward to cut the paper, the movable plate 81 is squeezed by the empty roll 4 and the wound paper roll, the angle between the movable plate 81 and the cutter 3 will become smaller, the elastic member will be compressed, and through the squeezing between the movable plate 81 and the empty roll 4 and the movable plate 81 and the wound paper roll, the end of the paper at the cutting position can be better bonded to the empty roll 4 and the wound paper roll respectively. When the movable plate 81 is used to cut the paper, the spacing size between the empty roll 4 and the wound paper roll is more applicable, which is convenient for cutting the paper.

[0034] In some embodiments, Figure 1 and Figure 2 As shown, the driving mechanism three also includes a driving member five (not shown in the figure) for driving the chuck 22 to move along the width direction of the frame 1. In this embodiment, the sliding member 522 and the connecting rod 524 are no longer provided, and the driving mode for the up and down movement of the cutter 3 is separated from the driving mode for the two chuck assemblies to approach each other, that is, the up and down movement of the cutter 3 and the mutual approach of the two chuck assemblies are completed by independent driving modes, wherein the driving member three is controlled to drive the moving member 51 and the cutter 3 installed on the upper end of the moving member 51 to move up and down, the driving member five can be an electric push rod, and can be extended and retracted in the left and right directions, and the driving member five can be controlled to make the two chuck assemblies approach or move away from each other. When cutting paper, the driving member five is first controlled to make the two chuck assemblies approach each other to a set distance, that is, the empty roll 4 and the wound paper roll are approached to each other until the cutter 3 just passes through, and then the cutter 3 is driven by the driving member three to move upward to cut the paper.

[0035] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
