Description

Technical Field

[0001] This utility model relates to a paper cutter, specifically to a lifting drive mechanism for the paper feed table of a paper cutter. Background Technology

[0002] A paper cutter is a specialized piece of equipment used for cutting paper. One type of paper cutter is used to cut stacked paper. During operation, the stacked paper needs to be fed onto a paper feed table, and the paper feed table is moved and raised to transfer the paper stack. Traditional paper feed table lifting and driving mechanisms use a single chain drive structure. This structure has a drawback in practical use: generally, software controls the motor to drive the chain, raising the paper feed table to its position and then immediately stopping the motor to achieve positioning. In actual use, because the motor stops instantaneously, the paper feed table inevitably retains some inertia during its ascent, causing vibration after it reaches its position. This can easily lead to a slight shift in the position of the paper stack, affecting the quality of paper feeding. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide a lifting drive mechanism for a paper feed table of a paper cutter to solve the above-mentioned problem.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A lifting drive mechanism for a paper feed table of a paper cutter includes a paper feed platform mounted on a lifting seat. The lifting seat is connected to a drive chain that passes around a drive sprocket, which is connected to the output end of a drive motor. The lifting seat has a first sensing part and a second sensing part arranged vertically at intervals. Sensors capable of sensing the first and second sensing parts are arranged along the movement path of the lifting seat. The sensors are mounted on a lifting frame, which is connected to a lifting adjustment assembly. An elastic pressing member is provided at the top position of the lifting frame corresponding to the lifting seat. When the sensor senses the first sensing part, it can feed back information to a controller, which can control the drive motor to decelerate. At this time, the lifting seat presses against the elastic pressing member. When the sensor senses the second sensing part, it can feed back information to the controller, which can control the drive motor to stop rotating.

[0006] The elastic pressing member includes a pressure plate that can contact the lifting seat, and the pressure plate and the lifting frame are connected by a spring.

[0007] The lifting seat is connected to a slide, and the frame is provided with a slide rail that cooperates with the slide.

[0008] The lifting adjustment assembly includes an adjustment rod rotatably mounted on the frame, a first helical gear on the adjustment rod, the first helical gear meshing with a second helical gear, the second helical gear being connected to an adjustment screw, the adjustment screw being screwed to the lifting frame, and a guide assembly corresponding to the lifting frame.

[0009] The above-mentioned technical solution provides a lifting drive mechanism for the paper feed table of a paper cutter. By setting a sensing structure, the mechanism can detect when the paper feed table has risen to the correct position and control the motor to decelerate and stop before the paper feed table reaches the correct position. This reduces the inertia of the paper feed table after it has risen to the correct position. In addition, by setting an elastic squeezing component, the mechanism can achieve damping and vibration reduction when the paper feed table reaches the correct position, further reducing the vibration of the paper feed table after it has risen to the correct position, ensuring the stability of the paper stack position, and thus improving the quality of paper delivery.

[0013] As shown in the figure, the present invention discloses a lifting drive mechanism for a paper feed table of a paper cutter, including a paper feed platform 1, which is mounted on a lifting seat 2. The lifting seat 2 is connected to a drive chain 5, which passes around a drive sprocket 6. The drive sprocket 6 is connected to the output end of a drive motor 7. The lifting seat 2 has a first sensing part 4 and a second sensing part 3 arranged vertically at intervals. A sensor 13 is provided on the corresponding movement path of the lifting seat 2 to sense the first and second sensing parts. The sensor 13 is mounted on a lifting frame 12, which is connected to a lifting adjustment assembly. An elastic pressing member is provided on the lifting frame 12 at the top position corresponding to the lifting seat 2. When the sensor 13 senses the first sensing part 4, it can feed back information to the controller. The controller can control the drive motor 7 to decelerate, and at this time, the lifting seat 2 presses the elastic pressing member. When the sensor 13 senses the second sensing part 3, it can feed back information to the controller. The controller can control the drive motor 7 to stop rotating.

[0014] Furthermore, the elastic compression member includes a pressure plate 14 that can contact the lifting seat 2, and the pressure plate 14 and the lifting frame 12 are connected by a spring 15.

[0015] Furthermore, a slide 17 is connected to the lifting seat 2, and a slide rail 16 that mates with the slide 17 is provided on the frame to guide the lifting of the lifting seat 2.

[0016] Furthermore, the lifting adjustment assembly includes an adjusting rod 9 rotatably mounted on the frame. A first helical gear 8 is mounted on the adjusting rod 9, meshing with a second helical gear 10. The second helical gear 10 is connected to an adjusting screw 11, which is screwed to a lifting frame 12. A guide assembly is provided corresponding to the lifting frame 12; the guide assembly can be a guide post passing through the lifting frame 12. Using this structure, by controlling the rotation of the adjusting rod 9 and the gear transmission, the adjusting screw 11 can be rotated, thereby driving the lifting frame 12 to rise and fall, thus adjusting the set height of the lifting seat 2.

[0017] The working principle of this utility model is as follows: By controlling the drive motor 7 to drive the drive sprocket 6 to rotate, and driving the drive chain 5 to move, the lifting seat 2 and the paper feeding platform 1 are lifted and lowered. When the paper feeding platform 1 is controlled to rise, when the paper feeding platform 1 is about to rise to the set height, the sensor 13 will first sense the first sensing part 4 and feed back information to the controller. Then the controller controls the drive motor 7 to decelerate. At this time, the lifting seat 2 contacts the pressure plate 14 and compresses the spring 15. When the sensor 13 senses the second sensing part 3, it feeds back information to the controller, and the controller can control the drive motor 7 to stop rotating, so as to realize the deceleration and rise of the paper feeding platform 1 to the set position and the damping buffer, ensuring the smoothness of the rise of the paper feeding platform 1.
