[0024] In order to describe the present utility model more clearly, the present utility model will be further described below with reference to the accompanying drawings.

[0025] In the following description, specific example details are given to provide a deeper understanding of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. It should be understood that the specific embodiments are only used to explain the present utility model and are not used to limit the present utility model.

[0026] It should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the described features, wholes, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components or their combinations.

[0027] Please refer to Figures 1 to 5 , the present utility model includes a vertical plate 1 and a roller 2. A first bearing 3 is provided at the center of the vertical plate 1. Both ends of the roller 2 are connected to two vertical plates 1 through the first bearing 3. Card slots 4 are provided on the sides of the two vertical plates 1. It also includes a clamping rod 5 and a rack 6. One end of the clamping rod 5 is fixedly clamped with the card slot 4, and the other end is fixed to the rack 6. The rack 6 meshes with a gear 7, and the gear 7 is connected to a rotating motor 10.

[0028] Further, in the present utility model, a magnetic powder clutch 8 is further included. The gear 7 is connected to the rotary motor 10 through the magnetic powder clutch 8. The gear 7 is fixedly sleeved on the output shaft of the magnetic powder clutch 8, and the input shaft of the magnetic powder clutch 8 is connected to the rotary motor 10. By providing the magnetic powder clutch 8 between the connection of the gear 7 and the rotary motor 10, the rotation speed and rotation direction of the gear 7 can be better controlled.

[0029] Further, in the present utility model, a coupling 9 is further included. The magnetic powder clutch 8 is connected to the rotary motor 10 through the coupling 9. One end of the coupling 9 is connected to the input shaft of the magnetic powder clutch 8, and the other end is connected to the output shaft of the rotary motor 10. By installing the coupling 9, the rotational movement of the output shaft of the rotary motor 10 is transmitted to the input shaft of the magnetic powder separator 8, making the transmission more precise.

[0030] Turn on the rotary motor 10 and control the magnitude and direction of the current, thereby finally controlling the rotation speed and rotation direction of the output shaft of the magnetic powder clutch 8. At the same time, the gear 7 is sleeved on the output shaft of the magnetic powder clutch 8 and meshes with the rack 6, so that the rotational movement of the output shaft is converted into the linear movement of the rack 6, and the rack 6 is fixedly connected to the clamping rod 5 to realize the transmission of the rack 6 to the clamping rod 5 for linear movement. Therefore, by controlling the magnitude and direction of the input current, the pushing and pulling function of the clamping rod 5 can be controlled. Among them, the structure of the gear and the rack meshing is only a transmission mechanism, which is included but not limited to this structural form in this solution.

[0031] Further, in the present utility model, a second bearing 11 is further included. The second bearing 11 is installed on the side of the vertical plate 1 away from the card slot 4. Half of the arc surface of the second bearing 11 remains on the vertical plate 1, and the other half protrudes from the vertical plate 1. The protruding arc contact surface of the second bearing 11 is in linear contact with the inclined block 12. The inclined block 12 is sleeved on the ball screw 13. The ball screw 13 is placed parallel to the side surface of the vertical plate 1, and the ball screw 13 is connected to the servo motor 14.

[0032] By controlling the servo motor 14 to rotate the ball screw 13, the inclined block 12 can perform a linear movement on the ball screw 13. When the motor pushes the roller 2 into place, the second bearing 11 installed on the vertical plate 1 connected to the roller 2 abuts against the inclined block 12. The inclined surface of the inclined block 12 is in linear contact with the arc contact surface of the second bearing 11. By controlling the servo motor 14 in real time to adjust the linear movement of the inclined block 12 along the direction of the ball screw 13, different positions of the inclined surface of the inclined block 12 can abut against the arc contact surface of the second bearing 11 to finely adjust the pushing distance of the roller 2 in real time, so that it reaches a more accurate position.

[0033] Please refer to Figure 1 、 Figure 2 and Figure 4, in the present utility model, it further includes a bottom plate 15. The bottom plate 15 is used to carry two vertical plates 1. The bottoms of the two vertical plates 1 are both fixed to the bottom plate 15. On the side of the bottom plate 15 away from the vertical plate 1, two first sliders 16 are also installed. The two first sliders 16 are slidably connected to a first slide rail 17. By installing the first sliders 16 on the bottom plate 15 and connecting the first sliders 16 to the first slide rail 17, the roller 2 can perform linear motion within a fixed track.

[0034] Further, in the present utility model, the side surface of the installation slot 4 of the vertical plate 1 is flush with the side piece of the bottom plate 15. At the same time, it further includes a connecting block 18. One side of the connecting block 18 is fixed to the side surface of the installation slot 4 of the vertical plate 1 and the side surface of the bottom plate 15 at the same time, so that the vertical plate 1 and the bottom plate 15 form a second fixing surface to prevent the clamping rod 5 from pushing the slot 4 and acting on the side surface of the vertical plate 1, resulting in the vertical plate 1 detaching from the bottom plate 15.

[0035] Please refer to Figure 3 , in the present utility model, a second slider 19 is installed on the side of the rack 6 away from the gear 7. The second slider 19 is slidably connected to a second slide rail 20. By installing the second slider 19 on the rack 6 and connecting it to the second slide rail 20, the rotation of the gear 7 drives the rack 6 to perform linear motion on the second slide rail 20 to drive the movement of the clamping rod 5.

[0036] Further, in the present utility model, it further includes a pressure sensor 21. The pressure sensor 21 is installed on the contact surface between the slot 4 and the clamping rod 5. This sensor is used to sense the thrust of the clamping rod 5 on the slot 4. By monitoring the thrust in real time, the magnitude of the input current is adjusted and the linear contact surface between the inclined block 12 and the second bearing 11 controlled by the servo motor 14 is adjusted to more precisely control the pushing distance of the roller 2.

[0037] The advantages of the present utility model are as follows:

[0038] 1. Through the coordinated operation of the clamping rod, rack, gear, magnetic powder clutch and motor, the present utility model can realize the function of pushing and pulling the vertical plate, and can also precisely control the pushing distance of the roller by adjusting the magnitude of the current.

[0039] 2. Through the coordinated operation of the second bearing, inclined block, ball screw and servo motor, the present utility model can accurately control the pushing distance of the roller in real time so that the roller reaches the predetermined position.

[0040] The above-disclosed are only several specific embodiments of the present utility model. However, the present utility model is not limited thereto. Any changes that can be thought of by those skilled in the art should fall within the protection scope of the present utility model.
