These cut paper tubes can be customized according to customer requirements, and during use, the one-way insertion of the paper tube requires the paper tube to be inserted from one end to the cutting position, and then cut, and then the remaining paper tube needs to be taken out.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6 The utility model provides a two-way insertion type paper tube precision cutting machine: it includes a gear box base 1 and a two-way mechanism 5, the inner surface of the gear box base 1 is rotatably connected with a rotating column 2, the top surface of the rotating column 2 is fixedly connected with a cutting sleeve 3, the inner surface of the cutting sleeve 3 is fixedly connected with a paper tube clamp 4, the outer surface of the gear box base 1 is provided with a two-way mechanism 5, and the outer surface of the gear box base 1 is provided with a cutting mechanism 6.

[0022] Furthermore, the bidirectional mechanism 5 includes an electric motor 501, an active sector gear 502, an active gear 503, an idler gear 504, a driven gear 505 and a driven sector gear 506. The outer surface of the gear box base 1 is fixedly connected with the electric motor 501, the inner surface of the gear box base 1 is rotatably connected with the active sector gear 502, the bottom surface of the active sector gear 502 is fixedly connected with the active gear 503, the inner surface of the gear box base 1 is rotatably connected with the idler gear 504, the inner surface of the gear box base 1 is rotatably connected with the driven gear 505, and the top surface of the driven gear 505 is fixedly connected with the driven sector gear 506. Through the arrangement of the electric motor 501, the active sector gear 502, the active gear 503, the idler gear 504, the driven gear 505 and the driven sector gear 506, cutting is required during use. The paper tube is placed in the paper tube clamp 4 in the cutting sleeve 3 and clamped. At this time, the electric motor 501 is started to drive the driving gear 503 to rotate. The driving gear 503 is meshed with the driven gear 505 to rotate simultaneously and in opposite directions. The driving gear 503 and the driven gear 505 respectively drive the driving sector gear 502 and the driven sector gear 506 on their surfaces to rotate and in opposite directions. Since only one side of the driving sector gear 502 and the driven sector gear 506 are meshed with the idler gear 504, the idler gear 504 can be driven to rotate only when meshed, so that the idler gear 504 only rotates half a circle each time and returns. In this way, the idler gear 504 can drive the rotating column 2 and the cutting sleeve 3 at the top to rotate, so that the ends of the paper tube can be rotated to the cutting mechanism 6 for cutting. In this way, only one end needs to input the paper tube and the other end needs to be cut to achieve the effect of two-way cutting, and the cutting is more efficient and safer.

[0023] Furthermore, the output end of the electric motor 501 passes through the inner surface of the gear box base 1 and is fixedly connected to the driving gear 503. The driving gear 503 is rotatably connected to the inner surface of the gear box base 1. The driving gear 503 is meshed with the driven gear 505. The electric motor 501 drives the driving gear 503 and the driven gear 505 to rotate in opposite directions.

[0024] Furthermore, the idler wheel 504 is meshed with both the active sector gear 502 and the driven sector gear 506, and the idler wheel 504 is fixedly connected to the rotating column 2. Only one side of the active sector gear 502 and the driven sector gear 506 is meshed with the idler wheel 504, and only when they are meshed can the idler wheel 504 be driven to rotate, so that the idler wheel 504 only rotates half a circle each time and returns, driving the rotating column 2 and the cutting sleeve 3 at the top to rotate.

[0025] Furthermore, the cutting mechanism 6 includes a support frame 601, a cutting knife 602, a limiting column 603, a reset spring 604, a servo motor 605, a rotating disk 606, a rotating column 607 and a connecting rope 608. The outer surface of the gear box base 1 is fixedly connected to the support frame 601, the inner surface of the support frame 601 is slidably connected to the cutting knife 602, the inner surface of the support frame 601 is fixedly connected to the limiting column 603, the outer surface of the limiting column 603 is sleeved with a reset spring 604, the outer surface of the gear box base 1 is fixedly connected to the servo motor 605, the output end of the servo motor 605 is fixedly connected to the rotating disk 606, the outer surface of the rotating disk 606 is rotatably connected to the rotating column 607, and the outer surface of the rotating column 607 is sleeved with a connecting rope 608, through the setting of the support frame 601, the cutting knife 602, the limiting column 603, the reset spring 604, the servo motor 605, the rotating disk 606, the rotating column 607 and the connecting rope 608, during use, the cutting knife 602 can slide up and down in the support frame 601 and the moving range is limited by the limiting column 603. The reset spring 604 on the limiting column 603 allows the cutting knife 602 to recover upward after being pressed down so that it can work continuously. The connecting rope 608 is put on the rotating column 607 of the rotating disk 606, and the servo motor 605 is started to rotate it. Different rotating columns 607 are at different distances from the center of the circle, and the moving range of the cutting knife 602 is also different when in use, and the cutting knife 602 at the top is pulled downward to cut the paper tube.

[0026] Furthermore, there are two support frames 601 and they are symmetrically distributed. The limiting posts 603 penetrate the cutting knife 602 . The symmetrical support frames 601 support the cutting knife 602 and both sides of the rotating disk 606 at the same time. The limiting posts 603 limit the moving range of the cutting knife 602 .

[0027] Furthermore, the outer surface of the rotating disk 606 is slidably connected to the support frame 601, and the other end of the connecting rope 608 is sleeved on the outer surface of the cutting knife 602. The number of rotating columns 607 is three. The support frame 601 supports both sides of the rotating disk 606 at the same time. The connecting rope 608 connects the cutting knife 602 and the rotating disk 606. When the rotating disk 606 rotates, it continuously pulls the cutting knife 602 on the top to move up and down.

[0028] Working principle: A two-way insertion paper tube precision cutting machine. During use, the paper tube to be cut is placed in the paper tube clamp 4 in the cutting sleeve 3 and clamped. At this time, the electric motor 501 is started to drive the driving gear 503 to rotate. The driving gear 503 is meshed with the driven gear 505 to rotate at the same time and in opposite directions. The driving gear 503 and the driven gear 505 respectively drive the driving sector gear 502 and the driven sector gear 506 on their surfaces to rotate and in opposite directions. Since only one side of the driving sector gear 502 and the driven sector gear 506 is meshed with the idler gear 504, the idler gear 504 can be driven to rotate only when meshed, so that the idler gear 504 only rotates half a circle each time and returns, so that the idler gear 504 can drive the rotating column 2 on the top and the cutting sleeve 3 is rotated so that both ends of the paper tube can be rotated to the cutting mechanism 6 for cutting. In this way, the paper tube only needs to be input at one end and cut at the other end to achieve the effect of two-way cutting. The cutting knife 602 can slide up and down in the support frame 601 and limit the moving range through the limit column 603. The reset spring 604 on the limit column 603 allows the cutting knife 602 to recover upward after being pressed down so that it can work continuously. The connecting rope 608 is put on the rotating column 607 of the rotating disk 606, and the servo motor 605 is started to rotate it. Different rotating columns 607 are at different distances from the center of the circle, and the moving range of the cutting knife 602 is also different when in use, and the cutting knife 602 at the top is pulled downward to cut the paper tube, thus completing a two-way insertion type paper tube precision cutting machine.
