Description

Technical Field

[0001] The utility model relates to the technical field of roll paper production, in particular to a cutting device for roll paper production. Background Art

[0002] In the production process of roll paper, multiple sheets of base paper are first compounded into one sheet of paper and then rolled up. Since the width of the base paper is relatively large, the length of the paper roll is also relatively long at this time and needs to be cut into shorter sections before it can be packaged. The cutting method is usually to use a fast-rotating cutter to perform continuous flipping and cutting during transportation.

[0003] The existing patent with announcement number CN219748098U discloses a cutting device for roll paper production, including a roller conveyor, an external fixed sleeve of the roller conveyor is provided with a support frame, and telescopic columns are fixedly installed on both sides of the support frame near the front and rear ends, the top of the telescopic column output shaft is fixedly connected with a lifting sleeve, the bottom surface of the lifting sleeve is fixedly connected with a bottom support spring, the bottom end of the bottom support spring is fixedly installed with a support bar, the top surface of the lifting sleeve is fixedly connected with a reset spring, the top of the reset spring is fixedly installed with a reset frame, the bottom surface of the reset frame is fixedly connected with a support plate extending to the bottom of the lifting sleeve, and the bottom end of the support plate is fixedly installed with a cutting knife.

[0004] However, the above device has the following problems when used:

[0005] When transporting the paper roll after production, the device simply uses a roller conveyor. During the movement, there is a lack of a mechanism to limit the movement trajectory. Since the paper roll is cylindrical, it is easy to move. If the reset frame is the same width as the paper roll, the support bars on the same straight line cannot contact the front and rear ends of the offset paper roll at the same time. If the reset frame is wider than the paper roll, although the deflected paper roll can be limited, the incision produced on the offset paper roll is not on the vertical plane of the paper roll, affecting the cutting effect.

[0006] Therefore, we propose a cutting device for roll paper production to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to solve the problems existing in the prior art, and the proposed cutting device for roll paper production can change the distance between the fixed part and the movable part, so that the two can play a limiting effect when loading, a clamping and fixing effect when cutting, and a material unloading channel when unloading. The operation is simple and convenient, and the efficiency is higher.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] See also Figures 1 to 6 The cutting device for roll paper production comprises a winding machine body 1, a collecting bin 3 and a conveying device 4. The conveying device 4 is located inside the collecting bin 3 and is used for conveying the cut roll paper.

[0029] The winding machine body 1 is provided with a discharge port 2, and the paper roll is wound with paper inside the winding machine body 1, and the wound roll paper is output through the discharge port 2. The winding machine body 1 has a corresponding mechanism inside to push, thereby realizing the movement of the roll paper.

[0030] A fixed plate 5 is fixedly mounted on the collecting bin 3, a fixed member 11 is fixedly mounted on the fixed plate 5, and a moving member 6 is slidably mounted on the fixed plate 5;

[0031] By moving the movable member 6, the distance between the fixed member 11 and the movable member 6 can be changed. When the roll paper is being transported, there is a certain distance between the fixed member 11 and the movable member 6. At this time, the movement trajectory of the roll paper can be limited so that the roll paper moves in the space between the fixed member 11 and the movable member 6.

[0032] After the paper roll is completely moved out, the movable member 6 is moved toward the fixed member 11, so that the movable member 6 contacts the fixed member 11, so that the paper roll can be completely inside the cylindrical space formed by the two. The paper roll fits the inner wall of the movable member 6 and the fixed member 11, and the paper roll has a certain elasticity, so that the clamping activity can be realized, which is convenient for the subsequent cutting activity.

[0033] A moving frame 8 is slidably mounted on the fixed plate 5, and a mounting plate 9 is evenly and evenly fixedly mounted on the moving frame 8, and a cutting blade 10 is arranged on the mounting plate 9. The driving source of the moving frame 8 can be a telescopic rod, a cylinder, a motor, an electromagnetic slider, etc., which is not described in detail because it is a prior art (not shown in the figure);

[0034] By moving the movable frame 8, the mounting plate 9 and the cutting blade 10 thereon are driven to move synchronously, and the cutting blade 10 realizes the cutting activity of the roll paper.

[0035] The fixed member 11 and the movable member 6 are provided with shuttle slits 15 at equal distances and uniformly, and the corresponding shuttle slits 15 on the two are located in the same plane;

[0036] The shuttle slot 15 is matched with the mounting plate 9 and the cutting blade 10 . It should be noted that the length of the cutting blade 10 is greater than the diameter of the moving part 6 .

[0037] When the mounting plate 9 moves, the cutting blade 10 moves from the corresponding shuttle slit 15, and the movement of the cutting blade 10 cuts the roll paper. The length between adjacent shuttle slits 15 is the width of the roll paper.

[0038] Two threaded rods 12 are rotatably installed inside the fixed plate 5. Both threaded rods 12 are threadedly connected to a nut pair 13. The nut pair 13 is fixedly connected to the movable part 6. By rotating the threaded rod 12, the nut pair 13 can be translated on the threaded rod 12, and then the movable part 6 is displaced, so that the distance between the movable part 6 and the fixed part 11 is changed, which is suitable for different usage scenarios.

[0039] A driving motor 7 is provided on the fixed plate 5, and the shaft output end of the driving motor 7 is fixedly connected to one of the threaded rods 12. The two threaded rods 12 are connected by a synchronous belt 14. By starting the driving motor 7, the threaded rod 12 connected to the driving motor 7 can be rotated, and the rotation of the threaded rod 12 is transmitted to the other threaded rod 12 through the synchronous belt 14, so that the two threaded rods 12 rotate synchronously.

[0040] Two blanking blocks 16 are fixedly mounted on one end of the mounting plate 9 away from the cutting blade 10 , and a through slot 17 adapted to the blanking blocks 16 is formed on the fixing member 11 .

[0041] After the cutting is completed, since the length of the cutting blade 10 is greater than the diameter of the movable member 6, the end of the cutting blade 10 that is away from the mounting plate 9 has passed through the paper roll, but the mounting plate 9 has not yet contacted the paper roll, causing the movable member 6 to move, so that the fixed member 11 and the movable member 6 are separated.

[0042] The movable frame 8 continues to move, and the unloading block 16 will pass through the through slot 17 to contact the cut paper roll, thereby driving the cut paper roll to move, so that the cut paper roll is separated from the fixed part 11. When the gap between the fixed part 11 and the movable part 6 is large enough for the cut paper roll to fall, the cut paper roll falls onto the conveying device 4, thereby realizing the conveying activity.

[0043] The through grooves 17 are located at the head and tail ends of the continuous space separated by the shuttle seam 15 on the fixing member 11, and the through grooves 17 are connected to the corresponding shuttle seam 15. The head and tail ends of the cut paper roll are respectively in contact with the cut paper roll, which can ensure the stability of the paper roll movement, thereby facilitating the unloading activity.

[0044] The fixing member 11 and the moving member 6 are both semicircular ring structures, and the two can form a complete cylinder to limit the position of the roll paper.

[0045] The working process of the utility model is as follows: first, the paper roll is conveyed and placed. At this time, there is a certain distance between the fixed part 11 and the movable part 6. The wound paper roll is output through the discharge port 2. The winding machine body 1 has a corresponding mechanism inside to push it, thereby realizing the movement of the paper roll, so that the paper roll moves in the space between the fixed part 11 and the movable part 6, and the movement trajectory of the paper roll can be limited.

[0046] After the paper roll is completely moved out, the drive motor 7 is started, the two threaded rods 12 rotate synchronously, the nut pair 13 translates on the threaded rod 12, and then the moving part 6 is displaced, and the moving part 6 is moved toward the side of the fixed part 11, so that the moving part 6 contacts the fixed part 11, so that the paper roll can be completely inside the cylindrical space formed by the two, and the paper roll fits with the inner walls of the moving part 6 and the fixed part 11 to realize the clamping activity.

[0047] By moving the movable frame 8, when the mounting plate 9 moves, the cutting blade 10 moves from the corresponding shuttle slot 15, and the movement of the cutting blade 10 cuts the roll paper.

[0048] When cutting is completed, the movable member 6 moves, so that the fixed member 11 and the movable member 6 are separated, and the movable frame 8 continues to move. The unloading block 16 will pass through the through slot 17 and contact with the cut paper roll, thereby driving the cut paper roll to move. The cut paper roll falls onto the conveying device 4 through the gap between the fixed member 11 and the movable member 6, thereby realizing the conveying activity of the cut paper roll.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
