Description

Technical Field

[0001] The utility model relates to a paper cutter, in particular to an anti-collision paper feeding mechanism of the paper cutter. Background Art

[0002] A paper cutter is a special device that can cut paper. The paper feeding mechanism is an important part of the paper cutter. When the paper feeding mechanism is working, it controls the paper picking workbench to move to the paper pile, and the roller on the paper picking workbench extends into the paper pile. The roller rotates to drive the paper to the paper picking workbench. Then the paper picking workbench moves to the next station, and the paper pushing board pushes the paper to the next station. When the paper pushing board moves in the pushing direction, the drag chain corresponding to the driving component of the paper pushing board will move together, and the drag chain will extend to the next station. If the operation calculation of the equipment is wrong at this time, the lifting frame will be controlled to drive the paper picking workbench and the paper pushing board to descend, and the drag chain will be lowered together. At this time, the drag chain will collide with other components in the next station, causing damage to the equipment. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide an anti-collision paper feeding mechanism of a paper cutter for solving the above-mentioned problem.

[0004] To this end, the utility model is implemented by adopting the following scheme:

[0006] The first mobile driving assembly includes a first motor arranged on the mobile frame, the output end of the first motor is connected to the first gear, the first gear is meshed with the first rack on the lifting frame, and the paper picking workbench is arranged on the mobile frame.

[0007] The second moving driving assembly includes a second motor arranged on the paper pushing rack, an output end of the second motor is connected to a second gear, and the second gear is meshed with a second rack on the lifting frame.

[0008] The first lifting drive assembly comprises a first cylinder, a piston rod of the first cylinder is connected to the paper pushing board, and a cylinder body of the first cylinder is arranged on the paper pushing rack.

[0009] The second lifting drive assembly includes a driving screw rod, which is connected to the output end of the third motor and is screwed to the lifting frame. A sliding seat is arranged on the lifting frame, and a sliding rail matching the sliding seat is arranged on the frame.

[0010] The sensing strip is a reflective strip.

[0011] The anti-collision paper feeding mechanism of the paper cutter of the above technical solution is achieved by additionally setting a sensing bar, and a sensor that can sense the sensing bar is set on the paper pushing rack. When the sensor senses the sensing bar, it indicates that the drag chain has been extended to the next workstation.

[0017] As shown in the figure, the anti-collision paper feeding mechanism of the paper cutter disclosed by the utility model includes a paper picking workbench 3 and a paper pushing paperboard 5. A rotatable paper picking roller 2 is installed at one end of the paper picking workbench 3. The paper picking workbench 3 is connected to a first mobile driving assembly. Specifically, the first mobile driving assembly includes a first motor 9 arranged on a mobile frame 12. The output end of the first motor 9 is connected to a first gear 10. The first gear 10 is meshed with a first rack 11 on a lifting frame 17. The paper picking workbench 3 is arranged on the mobile frame 12. By controlling the first motor 9 through the gear rack transmission, the mobile frame 12 and the paper picking workbench 3 can be driven to move horizontally. The paper pushing paperboard 5 is installed on the paper pushing frame 8 and connected to the first lifting driving assembly. Specifically, the first lifting driving assembly includes a first cylinder 4. The piston rod of the first cylinder 4 is connected to the paper pushing paperboard 5. The cylinder body of the first cylinder 4 is arranged on the paper pushing frame 8. By controlling the action of the first cylinder 4, the paper pushing paperboard 5 can be driven to move up and down. The paper pusher 8 is connected to the second mobile drive assembly and the drag chain assembly 7. Specifically, the second mobile drive assembly includes a second motor 13 arranged on the paper pusher 8. The output end of the second motor 13 is connected to the second gear 15. The second gear 15 is meshed with the second rack 14 on the lifting frame 17. By controlling the movement of the second motor 13 and transmitting through the gear rack, the paper pusher 8 can be driven to move horizontally. The paper picking workbench 3 and the paper pusher 8 are both arranged on the lifting frame 17. The lifting frame 17 is connected to the second lifting drive assembly. The second lifting drive assembly includes a driving screw 16. The driving screw 16 is connected to the output end of the third motor. The driving screw 16 is screwed to the lifting frame 17. A slide seat is arranged on the lifting frame 17, and a slide rail cooperating with the slide seat is arranged on the frame. By controlling the rotation of the driving screw 16, the lifting frame 17 can be driven to rise and fall. The lifting frame 17 is provided with a sensing strip 6, which is arranged along the moving path of the paper pushing rack 8. The paper pushing rack 8 is provided with a sensor 18 that can sense the sensing strip 6. When the sensor 18 senses the sensing strip 6, the drag chain assembly 7 extends to the next workstation, and the sensor 18 feeds back information and prohibits the second lifting drive assembly from driving the lifting frame to descend. In this embodiment, the sensing strip 6 is a reflective strip.

[0018] The working principle of the utility model is as follows: first, the paper picking workbench 3 is controlled to move to the paper pile, and the lifting frame 17 is controlled to drive the paper picking workbench 3 to rise to a suitable height, one end of the paper picking workbench 3 extends into the paper pile, and the roller 2 rotates to drive the paper pile to move onto the paper picking workbench 3, then the paper picking workbench 3 moves to separate from the paper pile and then rises to a position flush with the next station, the paper pushing paper board 5 descends and moves, and pushes the paper pile on the paper picking workbench 3 to be transported to the next station, by additionally providing a sensing bar 6, and providing a sensor 18 that can sense the sensing bar 6 on the paper pushing frame 8, during the movement of the paper pushing paper board 5, when the sensor 18 senses the sensing bar, it indicates that the drag chain assembly 7 has extended to the next station at this time, and then the sensor 18 feedbacks information and prohibits the second lifting drive assembly from moving, so as to avoid the lifting frame 17 driving the drag chain assembly 7 to descend together at this time, thereby ensuring that the drag chain assembly 7 will not collide with other components in the equipment and be damaged, thereby ensuring the stability of the equipment operation. In addition, when the equipment is shut down, if the operator pushes the paper pusher 8 to the position where the drag chain assembly 7 is in an extended state, the sensor 18 will immediately sense the sensing bar 6 after the equipment is powered on, and the paper pusher 8 can be controlled to reset to the initial position to perform the paper pushing operation; at the same time, in the process of separating the above-mentioned paper picking workbench 3 from the paper pile, the paper picking workbench 3 and the paper pushing paper board 5 move together until the sensor 18 senses the sensing bar 6, which means that the paper picking workbench 3 has been completely separated from the paper. At this time, the lifting frame 17 is controlled to drive the paper picking workbench 3 to rise to a suitable height to be flush with the paper receiving platform of the next workstation, so as to avoid the paper picking workbench 3 rising before it is separated from the paper, causing the paper pile to be partially lifted and scattered, thereby ensuring the neatness of paper transfer.
