[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1 to 3 As shown, a paper stack lifting and limiting control mechanism includes a control mechanism body 1 located on both sides of a feeder. Each control mechanism body 1 includes a mounting base 11, which is fixedly connected to the feeder 5. A paper pressing rod 121 is provided on one side of the bottom of the mounting base 11. The inner end of the paper pressing rod 121 is fixedly connected to a small seat 12, which is located on a fixed seat 13. A square shaft 131 is fixedly provided on the upper side of the inner end of the fixed seat 13. The small seat 12 and the square shaft 131 are rotatably connected to the mounting base 11 through a hinge shaft 14 that passes through them. An elastic support is provided between the left end of the small seat 12 and the fixed seat 13. A transmission rod 132 is fixedly mounted on the upper surface of the square shaft 131. The upper end of the transmission rod 132 intersects with the upper passive transmission rod 16, that is, the upper end of the transmission rod 132 contacts one side of the upper passive transmission rod 16. The passive transmission rod 16 is mounted on a rotating shaft 112, which is rotatably mounted on a mounting base 11. An elastic tension assembly is provided between one side of the passive transmission rod 16 and the mounting base 11. A sensing rod 17 is vertically fixed on the rotating shaft 113 on the other side opposite to the passive transmission rod 16. A sensor 18 that cooperates with the end of the sensing rod 17 is provided at the bottom of the mounting base 11. The sensor 18 is connected to the equipment control module (not shown in the figure), and the control module is connected to the servo motor (not shown in the figure) that drives the paper feeding platform 6. The control method and structure here are well known to those skilled in the art and will not be described in detail here. This mechanism utilizes a 10:1 leverage ratio coefficient to effectively control the paper stack height to send an upward signal for every 0.17mm decrease.

[0028] The elastic support includes a bolt 123 that runs vertically from top to bottom through the left end of the small seat 12. The protruding end of the bolt is located in the notch 122 at the lower left of the small seat 12. A vertical spring 15 is fitted onto the protruding end of the bolt 123 at the notch 122. The bottom of the spring 15 is pressed against the upper surface of the fixed seat 13.

[0029] The elastic traction assembly includes a first hook seat 114 fixedly mounted on a mounting base 11 on one side of the passive transmission rod 16, and a second hook seat 115 fixedly mounted on the mounting base 11 below the first hook seat 114. A tension spring 113 connects the first hook seat 114 and the second hook seat 115. Both the spring 15 and the tension spring 113 ensure improved stability of the mechanism during transmission.

[0030] The adjusting bolt 133 is screwed through the bottom surface of the right end of the top contact base 12 on the right side of the bottom surface of the fixed seat 13. The eccentric limiting pile 111 is fixed on the mounting seat 11 on both sides of the transmission rod 132. The height of the paper stack 3 can be adjusted to the accurate position through the adjusting bolt 133 on the fixed seat 13, so that the height of the paper stack 3 is always controlled between the required height of the feeder 5, thereby effectively ensuring the stability of the machine in the production process and improving the production efficiency.

[0031] The sensor 18 is a slot sensor, which is in the shape of a cuboid, and is embedded with a rectangular groove on the upper surface and is provided with a wiring column 181 at the bottom. The square mounting hole 19 is embedded on the mounting seat 11, and is sleeved on the square support rod 2. The inner end of the support rod 2 is fixedly connected with the feeder 5, and the fixed bolt is screwed on the side of the mounting seat 11 to extrude the support rod 2.

[0032] In use, the paper pressing rod 121 is a sensing rod, which is pressed on the upper surface of the paper stack 3, so that the height change of the paper stack can be monitored in real time. When the paper pressing rod 121 changes, the transmission rod 132 changes, and the upper end of the transmission rod 132 drives the passive transmission rod 16 to change, so that the sensing rod 17 on the other side changes. The height change of the paper stack 3 is finally converted into the position change between the sensing rod 17 and the sensor 18. When the sensing rod 17 at the sensor 18 changes in position, the control module sends a signal to the servo motor, so that the paper feeding platform 6 rises, and the paper stack 3 is ensured to be in the normal working range.
