s2, after being fixed, a mobile motor 5 is started, and then the two screws 2 are driven to synchronously rotate under the action of the two gears 3 and the chain 4, and then the two rectangular sliding blocks 6, the U-shaped plate 7 and the cutter 15 are driven to move, and the cutter 15 is moved to a proper position under the action of the two laser positioners 21;
s3, starting a hydraulic cylinder 8 to drive a concave mounting plate 9, a cutter seat 10, a cutter 15 and a protection plate 17 to synchronously move downwards, sensing by a plurality of sensors 19 when the protection plate 17 moves to the bottom, continuing to normally work when the plurality of sensors 19 synchronously sense objects, continuing to move downwards to cut printed products, enabling the protection plate 17 to be kept relatively static under the action of two sliding shafts 16 when the cutter 15 continues to move, driving the protection plate 17 to reset under the action of gravity and the elasticity of two compression springs 18 when the concave mounting plate 9 moves upwards, transmitting signals to a buzzer 20 when only a few sensors 19 sense the objects, and sending an alarm through the buzzer 20 to warn a worker to avoid being injured;
s4, when the cutter 15 needs to be disassembled, the two operation plates 14 are moved back to back, so that the two trapezoidal clamping blocks 11 are driven to move back to back, and the clamping and fixing with the two clamping grooves are released, so that the cutter 15 is taken down.
The working principle of the application is as follows: firstly, a printed product is pushed to be attached to a baffle plate, then a driving motor 23 is started, then a bidirectional screw rod 22 is driven to rotate under the meshing action of a first bevel gear 24 and a second bevel gear 25, then two square sliding blocks 26 are driven to move in opposite directions, when the two square sliding blocks 26 move, two square sliding rods 28 and a U-shaped pushing plate 31 are driven to move synchronously, when one U-shaped pushing plate 31 is contacted with the printed product, a fixing block 27 continues to move under the sliding action of the square sliding rods 28, then a convex pressing plate 34 is driven to move downwards along a circular shaft 33 under the action of a connecting rod 35 until the convex pressing plate 34 is contacted with the printed product, after the convex pressing plate 34 is pressed, the fixing block 27 is limited by the connecting rod 35, so that the fixing block 27, the square sliding rods 28 and the U-shaped pushing plate 31 are relatively static, and then the printed product is pushed to move until the other side convex pressing plate 34 is pressed against the printed product, and when the two convex pressing plates 34 are contacted with the printed product simultaneously, two travel switches 38 transmit signals to the driving motor 23 to realize a closing function, thus setting is not required, a quick fixing and a clamping function of the printed product can be realized, a cutting efficiency and a cutting quality can be improved. After the fixing, the mobile motor 5 is started, and then the two screws 2 are driven to synchronously rotate under the action of the two gears 3 and the chain 4, so that the two rectangular sliding blocks 6, the U-shaped plate 7 and the cutter 15 are driven to move, and the cutter 15 is moved to a proper position under the action of the two laser positioners 21. Then start pneumatic cylinder 8 and drive concave mounting panel 9, the cutter saddle 10, cut-off knife 15, guard plate 17 synchronous downward movement, when guard plate 17 moves to the bottom, a plurality of inductors 19 respond to, when a plurality of inductors 19 synchronous response arrives the object, continue normal work, cut-off knife 15 continues downward movement this moment, cut out printed matter, when cut-off knife 15 continues the motion, make guard plate 17 can keep relatively static under the effect of two slide shafts 16, when concave mounting panel 9 upward movement, drive guard plate 17 under the elastic action of gravity and two compression springs 18 and reset, when only a few inductors 19 respond to the object, it can transmit signal to buzzer 20 department, send the alarm through buzzer 20, in order to warn the staff and avoid receiving the injury, so set up, not only can play protect function to the staff through guard plate 17, and can not produce the influence to cutting process, the practicality is higher. When the cutter 15 needs to be disassembled, the two operation plates 14 are moved back to back, so that the two trapezoidal clamping blocks 11 are driven to move back to back, and the clamping and fixing with the two clamping grooves are further released, so that the cutter 15 is taken down for maintenance, and the operation of installation and disassembly is convenient and efficient.
