Summary of the invention

[0003] The purpose of the present invention is to solve the technical problems raised in the above background technology.

[0005] Preferably, a No. 1 spring is fixedly installed between the sheath and the extension rod, and the No. 1 spring is sleeved on the outer surface of the connecting rod. Here, the design of the No. 1 spring enables the paper separation wheel to better fit the upper surface of the paper, increases the friction between the paper separation wheel and the paper, and reduces the situation where no paper is brought out during the paper separation process.

[0006] Preferably, a connecting block is fixedly mounted on the other end of the slide bar, a rocker is rotatably connected to the interior of the connecting block, the other end of the rocker is rotatably connected to a turntable, and the output end of the No. 1 motor is fixedly mounted on the surface of the turntable. Here, the rocker connects the turntable and the slide bar, converting the rotary motion into precise linear reciprocating motion, and the optimized connecting rod mechanism reduces vibration and impact. At the same time, the paper feeding frequency can be adjusted by the motor speed, which reduces the difficulty of operation. The structure has high transmission efficiency, lower cost, and also reduces maintenance costs.

[0007] Preferably, a limiting groove is provided on the surface of one side plate at the exit of the No. 1 bottom plate and the No. 2 bottom plate, and a limiting rod is fixedly installed inside the limiting groove, and a slider is slidably connected to the surface of the limiting rod.

The diameter of the middle section of the guide column is the same as the diameter of the limiting hole, and the diameter of the upper section of the guide column is the same as the width of the No. 2 slide groove. Here, the use of the guide column and the connecting block realizes a stable connection of the device, and the inconsistent thickness of the upper and lower ends of the guide column makes the adjustment process more convenient.

[0011] Preferably, a transmission mechanism is fixedly installed on the surface of the side plates at the exit ends of the first and second bottom plates, and the transmission mechanism includes a transmission rod and a limit plate, the transmission rod is rotatably connected to the inside of the limit plate, the transmission rod includes a convex rod and a concave rod, a fixed block is fixedly installed on the surface of the convex rod, a fixed groove is opened inside the concave rod, and the fixed block is slidably connected inside the fixed groove. Here, the modular transmission mechanism supports flexible expansion, and the optimized low-resistance bearing and quick-release design ensure long-distance precise synchronous transportation, which is easy to maintain and meet the needs of different production scenarios.

[0012] Preferably, a positioning mechanism is provided inside the transmission mechanism, and the positioning mechanism includes a positioning plate, a screw and a handwheel.

The No. 1 spring ensures that the paper separation wheel is always pressed against the surface of the paper. The ratchet and the ratchet cooperate in the process of the paper separation mechanism moving back and forth, so that the device can separate the stacked papers, and reduce the possibility of the stacking of multiple papers entering the next process.

[0016] 3. In the present invention, by setting a limit plate, a positioning plate, a screw, a hand wheel and a transmission rod structure, the hand wheel is turned to rotate the screw, and the opposite threads at both ends of the screw drive the positioning plates at both ends to move in opposite directions, thereby realizing the positioning of the paper during the paper feeding process of the device, preventing the paper from being offset due to wind force or other reasons during the transportation process, causing errors or losses during processing, improving production efficiency and reducing production losses.

[0033] Working principle: When the device needs to be used to feed paper, the guide post 27 is pressed to compress the No. 3 spring 28, so that the guide post 27 moves downward, the middle section of the guide post 27 leaves the limiting hole 24, the lock between the guide post 27 and the connecting plate 23 is released, and the thinner upper section of the guide post 27 moves into the limiting hole 24, and the No. 1 bottom plate 1 and the No. 2 bottom plate 2 are pulled, so that the slide plate 21, the protruding column 174 and the fixing block 2913 slide inside the connecting groove 22, the guide groove 173 and the fixing groove 2914, and at the same time, the upper section of the guide post 27 slides in the No. 2 slide groove 25. When the device is adjusted to the position where the paper can be fed, the guide post 27 is pressed to the bottom plate 1 and the No. 2 bottom plate 23, and the upper section of the guide post 27 slides in the No. 2 slide groove 25. When the size of the paper is to be placed, the paper is placed on the upper surface of the No. 1 bottom plate 1 and the No. 2 bottom plate 2. The connecting rod 83 drives the paper separation wheel 85 to be close to the surface of the paper under the action of the No. 1 spring 88, and the No. 1 motor 12 and the No. 2 motor 20 are started. The No. 1 motor 12 drives the turntable 11 to rotate, and the rotation of the turntable 11 drives the rocker 10 to make a circular motion. The rocker 10 drives the slide bar 6 to slide back and forth inside the ring 5. The cross bar 7 moves together under the action of the slide bar 6, and the cross bar 7 drives the paper separation mechanism 8 to reciprocate. When the paper separation mechanism 8 moves forward, the paper separation wheel 85 is close to the paper surface. When the paper separation mechanism 8 moves backward, the ratchet 86 and the ratchet 87 are unlocked, and the paper separation wheel 85 rotates without pushing the paper. When the separated paper is pushed out, it contacts the roller 17, and the second motor 20 drives the large gear 18 to rotate. Due to the different gear ratios, the linear speed of the small gear 19 is greater than the linear speed of the large gear 18, so that the rotation speed of the roller 17 connected to the small gear 19 is faster, and the paper enters between the two groups of rollers 17 and the limit groove 13. The No. 2 spring 16 makes the No. 1 roller 17 and the No. 2 roller 17 close to each other, and the stacked papers are separated due to the different rotation speeds of the upper and lower rollers 17, so that the papers can enter the transmission mechanism 29 one by one. When the papers enter the transmission mechanism 29, the hand wheel 303 is turned, and the hand wheel 303 drives the screw rod 302 to rotate. The reverse threads at both ends of the screw rod 302 drive the positioning plates 301 to adjust in opposite directions. When the spacing between the positioning plates 301 is adjusted to a distance that is just suitable for the paper to pass through without offset, the transmission rod 291 drives the paper to move forward.
