Description

Technical Field

[0001] The present invention relates to the technical field of paper winding, and particularly relates to a paper winding device. Background Art

[0002] In the production and processing of paper, in order to facilitate the storage and transportation of finished paper, the paper is usually stored in a wound manner. Winding the paper can not only reduce the volume of the paper, but also protect the smoothness of the paper to the greatest extent.

[0003] A patent document with the authorization announcement number CN208166150U discloses a paper automatic winding and rewinding device, including a control device, a driving device, a frame, a rotating roller, a turning roller, a driving roller, a motor and a paper cutter. The control device is connected to the driving device. The driving device includes a motor, a driving gear and a transmission gear. The motor is connected to the driving gear. The driving gear and the transmission gear are meshed. The transmission gear is provided with a driving roller. The driving roller is connected to the frame and is connected to the turning roller through the frame. There are two rotating rollers on the turning roller. The rotating rollers are inserted at both ends of the turning roller. Motors are provided on both rotating rollers. A lifting frame is provided on the frame. A paper cutter is provided on the lifting frame. The paper cutter is connected to the control device. In this solution, when the paper winding is completed on one paper tube, the turning roller is controlled to rotate counterclockwise by 180°, so that the rotating roller at the rear lower part and the rotating roller at the upper front part are interchanged in position. At the same time, the paper cutter on the lifting frame descends to cut the paper. The paper adheres to the double-sided adhesive tape on the empty rotating roller. The motor corresponding to the empty rotating roller starts to operate. At this time, the user can remove the wound paper roll and replace it with a new paper tube, and cycle the paper winding operation.

[0004] In the above technical solution, since the distance between the two rotating rollers is fixed, when the paper cutter descends to cut the paper, among the two paper ends at the cutting position, there will be a redundant part between one end and the position where it adheres to the double-sided adhesive tape, and there will also be a redundant part between the other end and the wound paper roll after winding. As a result, after the paper is cut, it is necessary to process the paper of the two redundant parts again, which is time-consuming and laborious, and will reduce the paper winding efficiency. If not processed, the paper will be wrinkled. Summary of the Invention

[0005] The present invention provides a paper winding device, aiming to solve the problem in the related technology that after the paper is cut, it is necessary to process the paper of the two redundant parts again, which will reduce the paper winding efficiency.

The guide wheels are in a forward direction and a backward direction respectively.

[0007] The beneficial effect of the present invention is that when the present invention is rolling and cutting paper, the end of the paper at the cutting position can be respectively adhered to the empty roll and the rolled paper roll, so that there is no redundant paper at the cutting position and no need for reprocessing, which can improve the paper rolling efficiency and facilitate use.

[0009] Preferably, the driving mechanism three also includes two connecting components, and the two connecting components correspond to the two positioning plates respectively. The connecting components include a push rod, a sliding member 1 and two sliding members 2. The push rod is fixedly installed on the upper part of the movable member, and the sliding member 1 is slidably connected to the positioning plate up and down and is located directly above the push rod. The two sliding members 2 are respectively rotatably connected to the two chucks, and the sliding member 2 is slidably connected to the positioning plate.

The installation frame is slidably connected to the machine frame and can move along the width direction of the machine frame. The moving member is slidably connected to the installation frame up and down. The effect is that when winding and cutting paper, the position of the installation frame can be adjusted according to the diameter of the paper roll after winding is completed, so that the installation frame is located at the middle position between the empty reel and the wound paper roll, facilitating the bonding of the paper end portions at the cutting position to the empty reel and the wound paper roll respectively.

[0012] Preferably, elastic telescopic rods are provided on both the upper and lower sides of the first sliding member. The outer ends of the two elastic telescopic rods facing each other are fixedly connected to the positioning plate, and the inner ends facing each other abut against the upper and lower sides of the first sliding member respectively.

The effect is that the movable plates have a wider applicable range for the spacing size between the empty reel and the wound paper roll during cutting, facilitating the cutting of the paper.

[0015] Adopting the above technical solution, the beneficial effect of the present invention is as follows: When the present invention winds paper, after winding the paper on one side chuck assembly is completed, the position of the other side chuck assembly is swapped with the wound paper roll. Then, after applying glue or sticking double-sided tape on the upper surface of the paper at the position to be cut, the two chuck assemblies are moved closer to each other, and the cutting knife is moved upward. When the empty reel on one side chuck assembly and the wound paper roll on the other side chuck assembly move closer to each other just enough for the cutting knife to pass through, the cutting knife will cut the paper, and the paper end portions at the cutting position can be respectively bonded to the empty reel and the wound paper roll, so that there is no redundant paper at the cutting position and no further processing is required, which can improve the paper winding efficiency and is convenient to use.

[0023] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] As Figures 1 to 3 shown, the paper winding device of the embodiment of the present invention includes a frame 1, two positioning plates 21, two chuck assemblies, a cutting knife 3, a first driving mechanism 9, a second driving mechanism, and a third driving mechanism.

[0025] The two positioning plates 21 are arranged along the length direction of the frame 1 and are respectively rotatably connected to the frame 1. 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-back direction, the width direction is defined as the left-right direction, the two positioning plates 21 are arranged opposite to each other in the front-back direction, the two chuck assemblies are arranged opposite to each other in the left-right direction, and the first driving mechanism 9 includes a motor, the output end of which is connected to the positioning plate 21 and can drive the positioning plate 21 to rotate.

[0026] As Figure 1 and Figure 2 shown, the chuck assembly includes a fourth driving member (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 respectively rotatably connected to the two positioning plates 21. The chuck 22 can slide along the width direction of the frame 1, and the fourth driving member can drive the chuck 22 to rotate.

[0027] Specifically, two chucks 22 in the chuck assembly are arranged opposite to each other in the front-rear direction. In this embodiment, the chuck 22 can be a six-jaw chuck. By controlling the jaws 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 a mature existing 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.

[0028] The 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 extend and retract in the front-rear direction. Its telescopic 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 front and back can be moved closer to or away from each other, so as to facilitate the installation of the two ends of the reel 4 on the two chucks 22 respectively and complete the positioning and fixing 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, by controlling the operation of the fourth driving member, the reel 4 can be driven to rotate and the paper can be wound.

[0029] As Figures 1 to 3 shown, the cutting knife 3 is slidably mounted up and down at the lower part between the two chuck assemblies. The third driving mechanism can drive the cutting knife 3 to move up and down and can also drive the two chucks 22 mounted on the same positioning plate 21 to move closer to each other.

[0030] Specifically, an installation frame 6 is provided at the lower part between the two chuck assemblies. The installation frame 6 is connected to the frame 1. The third driving mechanism includes a moving member 51 and a third driving member (not shown in the figure). The moving member 51 is slidably connected up and down to the installation frame 6. The cutting knife 3 is fixedly mounted on the upper part of the moving member 51. The third driving member can be an electric push rod, and its upper and lower ends are respectively fixedly connected to the moving member 51 and the installation frame 6. By controlling the extension and retraction of the third driving member, the moving member 51 and the cutting knife 3 fixedly mounted on the upper part of the moving member 51 can be driven to move up and down.

[0031] The third driving mechanism further includes two connection components facing each other in the front-rear direction. The two connection components respectively correspond to the two positioning plates 21. The connection component includes a top rod 521, a first sliding member 522, and two second sliding members 523. The top rod 521 is fixedly mounted on the upper part of the moving member 51. The first sliding member 522 is slidably connected up and down to the positioning plate 21 and is located directly above the top rod 521. The two second sliding members 523 are respectively rotatably connected to the two chucks 22. The second sliding member 523 is slidably connected to the positioning plate 21 and can slide in the left-right direction. A connecting rod 524 is provided between the second sliding member 523 and the first sliding member 522. The two ends of the connecting rod 524 are respectively hinged to the first sliding member 522 and the second sliding member 523. Among them, the second driving mechanism and the fourth driving member are both mounted on the second sliding member 523 and can move with the second sliding member 523.

[0032] When the present invention is in use, first control the driving mechanism II and the chuck 22. Fix and install the winding drum 4 on the chuck assembly on the left side. Then control the driving member IV to drive the chuck 22 and the winding drum 4 on the left side to rotate counterclockwise to wind the paper coming from the left side. When the wound paper reaches the set standard, control the driving mechanism I 9 to drive the positioning plate 21 to rotate counterclockwise by 180°, so as to change the positions of the two chuck assemblies at the initial time. At this time, the winding drum 4 that has wound the paper will move to the right side, and continue to fix and install a new winding drum 4 on the chuck assembly on the left side. Next, first apply glue or paste double-sided tape on the upper surface of the paper at the position to be cut. Then control the driving member III to drive the moving member 51 and the cutter 3 and the ejector rod 521 fixedly installed on the moving member 51 to move upward. Since the sliding member I 522 is directly above the ejector rod 521, when the ejector rod 521 moves upward, it will push the sliding member I 522 to slide upward. Under the action of the connecting rod 524, it will drive the sliding member II 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 winding drum 4 and the wound paper roll approach each other just enough for the cutter 3 to pass through, the upward movement of the cutter 3 will cut the paper, and the paper ends at the cutting position can be respectively adhered to the empty winding drum 4 and the wound paper roll. Next, continue to control the rotation of the winding drum 4 on the left side, and the paper can be continuously wound, and the wound paper roll on the right side can be disassembled by controlling the driving mechanism II and the chuck 22.

[0033] In some embodiments, as Figure 1 and Figure 2 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 winding and cutting the paper, the position of the mounting frame 6 in the left-right direction can be adjusted according to the diameter of the paper roll after winding, so that the mounting frame 6 is located at the middle position between the empty winding drum 4 and the wound paper roll, which is convenient for the paper ends at the cutting position to be respectively adhered to the empty winding drum 4 and the wound paper roll.

[0034] In some embodiments, as Figure 2As shown, elastic telescopic rods 7 are provided on both the upper and lower sides of the first sliding member 522. The outer ends of the two elastic telescopic rods 7 facing each other are fixedly connected to the positioning plate 21, and the inner ends facing each other abut against the upper and lower sides of the first sliding member 522 respectively. That is, the upper end of the upper elastic telescopic rod 7 is fixedly connected to the positioning plate 21, and the lower end abuts against the first sliding member 522 in a fitting manner. The lower end of the lower elastic telescopic rod 7 is fixedly connected to the positioning plate 21, and the upper end abuts against the first sliding member 522 in a fitting manner. When the ejector rod 521 pushes the first sliding member 522 upward, the elastic telescopic rod 7 located on the upper side of the first sliding member 522 will be compressed. When the ejector rod 521 moves downward to reset, the first sliding member 522 will move downward to reset under the elastic pushing of the upper elastic telescopic rod 7.

[0035] In some embodiments, as Figure 1 and Figure 2 shown, the upper end of the cutting knife 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 cutting knife 3 from top to bottom. That is, the left inclined surface 811 inclines downward to the left, and the right inclined surface 811 inclines downward to the right. When the cutting knife 3 moves upward to cut the paper, the inclined surfaces 811 on both sides of the cutting knife 3 can make the paper ends at the cutting position better adhere to the empty reel 4 and the wound paper roll respectively.

[0036] In some embodiments, as Figure 1 and Figure 2 shown, movable plates 81 are provided on both sides below the cutting end. The upper ends of the movable plates 81 are rotatably connected to the cutting knife 3. The inclined surfaces 811 are located on the movable plates 81. An elastic member (not shown in the figure) is provided between the movable plates 81 and the cutting knife 3. The elastic member is a spring and can elastically push the movable plates 81 in the outer direction of the cutting knife 3. When the cutting knife 3 moves upward to cut the paper, the movable plates 81 are squeezed by the empty reel 4 and the wound paper roll. The angle between the movable plates 81 and the cutting knife 3 will become smaller, and the elastic member will be compressed. And through the squeezing between the movable plates 81 and the empty reel 4 and between the movable plates 81 and the wound paper roll, the paper ends at the cutting position can be better adhered to the empty reel 4 and the wound paper roll respectively. The movable plates 81 have a wider applicable range of the spacing dimension between the empty reel 4 and the wound paper roll when cutting the paper, which is convenient for cutting the paper.

[0037] In some embodiments, as Figure 1 and Figure 2As shown, the third driving mechanism further includes a fifth driving member (not shown in the figure) for driving the chuck 22 to move in the width direction of the frame 1. In this embodiment, the first sliding member 522 and the connecting rod 524 are no longer provided, and the driving method for moving the cutter 3 up and down is separated from the driving method for the two chuck assemblies to approach each other. That is, the up and down movement of the cutter 3 and the approach of the two chuck assemblies are both completed by independent driving methods. Among them, controlling the third driving member can drive the moving member 51 and the cutter 3 installed at the upper end of the moving member 51 to move up and down. The fifth driving member can be an electric push rod and can expand and contract in the left and right directions. Controlling the fifth driving member can make the two chuck assemblies approach or move away from each other. When cutting the paper, first control the fifth driving member to make the two chuck assemblies approach each other to a set distance, that is, make the empty reel 4 and the wound paper roll approach each other until the cutter 3 just passes through, and then drive the cutter 3 to move up by the third driving member to cut the paper.

[0038] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
