The automatic paper feeding mechanism is mainly used for cutting and cutting square paper, when in actual use, the paper is neatly stacked on the supporting plate 20 of the automatic feeding mechanism 1, one side of the paper is attached to the width adjusting plate 23 fixed on the first guide rod 22, the other width adjusting plate 23 is driven to be attached to the other side of the paper by rotating the knob 25 on the paper width adjusting device 21, the limited adjustment of the paper width is realized, the paper is prevented from being transversely offset when being loaded into the automatic feeding mechanism 1, the paper is kept at a fixed position, and meanwhile, the automatic feeding mechanism 1 can be suitable for paper with different sizes. The first sensor 12 on the automatic feeding mechanism 1 can monitor the height of the paper on the material platform 10 and transmit a signal to the controller 4, the controller 4 controls the first motor 16 to work, the first motor 16 drives the screw rod 15 to rotate, and then the material platform 10 is controlled to lift up and down along with the connecting seat 14 until the height of the paper on the material platform 10 is adjusted to a set height, the set height can be input and set through the controller 4, the Controller 4 is a PLC Controller, generally called a Programmable Logic Controller (Programmable Logic Controller), a digital electronic device having a microprocessor, the digital logic controller for automatic control can load the control instruction into the memory at any time for storage and execution, the programmable controller is modularly assembled by an internal CPU, an instruction and data memory, an input/output unit, a power module, a digital analog unit and the like.
When the paper gripping device 5 works, the second air cylinder 30 drives the transverse tube 31 to move downwards until the rubber suction cups 33 cling to the uppermost paper on the automatic feeding mechanism 1, the longitudinal moving distance of the rubber suction cups 33 is controlled by the stroke of the piston rods on the second air cylinder 30, in order to meet the use requirement, when the piston rods of the second air cylinders 30 stretch out to the maximum stroke, the rubber suction cups 33 cling to the uppermost paper on the automatic feeding mechanism 1 just, and the height of the paper on the material platform 10 can be controlled by the automatic feeding mechanism 1 to be always kept at the set height, so the effect of the scheme can be realized. When the rubber suction cups 33 cling to the paper, the air pump 34 pumps air in the transverse pipes 31 to enable the transverse pipes 31 and the hollow pipes 32 to generate negative pressure, so that the paper can be adsorbed on the rubber suction cups 33, then the piston rods of the second air cylinders 30 retract, the controller 4 controls the first air cylinders 26 to drive the cross beams 27 to move to the position above the deviation rectifying table 38, at the moment, the air pump 34 stops working, the negative pressure in the transverse pipes 31 and the hollow pipes 32 disappears, the paper drops on the deviation rectifying table 38 under the action of gravity, then the first air cylinders 26 drive the cross beams 27 to return to the position right above the feeding port 9, and the next operation is waited. When the paper gripping device 5 adsorbs the paper and passes through the separation roller 52 between the feeding port 9 and the deviation rectifying table 38, if two pieces of paper are adsorbed together, the paper which is not adsorbed by the rubber suction cup 33 falls under the action of friction force of the separation roller 52, so that the separation of the paper is realized, and the paper gripping device 5 is guaranteed to grip only one piece of paper at a time.
All be equipped with the cursor with fourth sensor 51 cooperation use on the paper that actually waits to cut, the paper drops to the platform 38 of rectifying of positioning mechanism 2, thereby fourth sensor 51 can detect out the position of paper through the position that detects the cursor, monitor out the paper skew when fourth sensor 51, feedback signal gives controller 4, controller 4 control two second motor 41's pivot produces the difference in rotational speed, make the transport speed of two conveyer belts 40 produce the difference, thereby realize rectifying to the paper, correct the position of paper. The paper touches stopper 50 and then can stop moving, combine the speed that conveyer belt 40 carried, conveyer belt 40 and stopper 50 distance, can wait to the paper and touch stopper 50 back through modes such as presetting time difference in PLC controller 4, the paper moves to between bottom plate 43 and the pressure strip 48 this moment, controller 4 control fourth cylinder 49, drive pressure strip 48 compresses tightly on the paper, bottom plate 43 and pressure strip 48 press from both sides the paper tight this moment, controller 4 control third cylinder 45 drive bottom plate 43 moves towards cutting mechanism 3, and then control paper moves to cutting mechanism 3. In order to avoid the paper from floating when moving on the deviation rectifying platform, the invention can realize better compaction effect on the paper by arranging the steel balls 55 to prevent the paper from floating, and the steel balls 55 can roll in the mounting holes 54 along with the movement of the paper, so that the influence on the movement of the paper driven by the conveyor belt 40 is small and can be ignored. Simultaneously, through setting up many with first elastic pressing piece 58 and second elastic pressing piece 60, also can realize better compressing tightly effect to the paper, first elastic pressing piece 58 all adopts the elastic steel piece that thickness is less than 0.02mm with second elastic pressing piece 60, can realize better compressing tightly effect to the paper, can prevent that the paper from floating and can not influence conveyer belt 40 and drive the paper and remove. Since the first elastic pressing piece 58 is disposed in the direction opposite to the conveying direction of the conveyor belt 40, the front end of the first elastic pressing piece 58 is designed to be inclined upward, so that the first elastic pressing piece 58 does not affect the movement of the paper. The positions of the cursors on the paper sheets with different sizes are different, and the position of the fourth sensor 51 can be adjusted to correspond to the position of the cursors on the paper sheets through the sensor position adjusting device 61, so that the deviation rectifying and positioning mechanism 2 can be suitable for different batches of paper sheets with different sizes and specifications. The position of the limiting block 50 can be adjusted through the adjusting bolt 72 and the second return spring 74, so that the limiting block 50 can be suitable for paper sheets with different sizes and specifications.
