The pallet transfer mechanism 10 includes a side wall 3, a pallet extraction device, a lifting device for driving the pallet extraction device to lift and lower, and a transfer device for driving the pallet extraction device to move horizontally. The pallet extraction device includes a moving frame 7, a front plug-in board, a rear plug-in board, and a driving device for driving the front plug-in board and the rear plug-in board to move longitudinally and horizontally. Components; the front plug-in plate and the rear plug-in plate both include a crossbeam 13 and a plug-in plate 17, at least two of the plug-in plates 17 are provided, generally two are sufficient, the crossbeam 13 is provided with a mounting rail 16, the plug-in plate 17 is slidably mounted on the rail 16, the position of the plug-in plate is adjusted according to the size of the card plate 11 and the position of the socket on the card plate, after the adjustment is completed, the plug-in plate 17 is fixed to the crossbeam 13 by a locking member, when adjusting, the locking member is loosened, and the plug-in plate 17 can move laterally on the rail 16, the locking member can be a conventional component such as a locking screw. The driving component includes a front driving component, a rear driving component and a linear guide 18, wherein the linear guide 18 is longitudinally arranged on the left mounting plate 19 and the right mounting plate of the moving frame, and the two ends of the crossbeam 13 are slidably arranged on the linear guide 18; the front driving component and the rear driving component both include a motor, a transmission wheel 12 and a transmission belt 14 arranged on the transmission wheel, wherein one transmission wheel is connected to the motor, and the motor and the transmission wheel 12 are both installed on the moving frame, the front plug plate is fixedly connected to the transmission belt of the front driving component, and the rear plug plate is fixedly connected to the transmission belt of the rear driving component, that is, the motor drives the transmission belt 14 to transmit, so that the front plug plate or the rear plug plate connected to the transmission belt moves longitudinally along the linear guide 18. The moving frame 7 is also provided with a limit component for controlling the downward movement height of the moving frame, and the limit component includes a double-rod cylinder 15 and a sensing switch. The double-rod cylinder 15 is vertically arranged, and the sensing switch cooperates with the piston rod of the double-rod cylinder. The sensing switch, the lifting device, the transfer device and the driving component are all connected with the electrical controller. When the moving frame 7 descends, the piston rod of the double-rod cylinder 15 first contacts the upper end surface of the card plate 11, and the moving frame 7 continues to descend, and the piston rod is forced to move up until the sensing switch senses the piston rod. The sensing switch sends the information to the electrical controller, and the electrical controller sends a command to the lifting device to stop it, and the moving frame 7 no longer moves down. At this time, the front plug-in board and the rear plug-in board just correspond to the socket position of the card plate 11, and then the card plate insertion and removal operation can be carried out.

[0020] The lifting device comprises a driving shaft 2, a chain meshed with a gear 1 on the driving shaft, a lifting guide rail 4 and a slide 5 slidably arranged on the lifting guide rail. The driving shaft 2 is driven by a motor. The lifting guide rail 4 is vertically installed on the side wall 3. The moving frame 7 is installed on the slide 5. The slide 5 is connected to the chain. The transfer device comprises a driving gear 6, a rack 9 meshed with the driving gear and a transverse guide rail 8. The rack 9 and the transverse guide rail 8 are both transversely arranged on the moving frame 7. The driving gear 6, the rack 9 and the transverse guide rail 8 are all equipped with two pairs of front and rear pairs. The driving gear 6 can be connected to the motor through the main shaft. The motor and the main shaft are both installed on the slide 5. The motor drives the main shaft to rotate, that is, drives the driving gear 6 to rotate. The slide 5 and the transverse guide rail 8 are slidably matched, which is equivalent to the moving frame 7 being arranged on the slide 5. The slide 5 of the present invention can be lifted and lowered along the lifting guide rail 4, and can also cooperate with the transverse guide rail 8 to make the moving frame 7 move transversely relative to the slide 5. Such a structure is more compact and reduces the equipment cost at the same time. When the movable frame 7 needs to be raised or lowered, the driving shaft 2 rotates to drive the chain transmission, so that the slide 5 rises or moves down along the lifting guide rail 4. The lifting of the slide 5 means the lifting of the movable frame 7; when the movable frame 7 needs to move laterally, the driving gear 6 rotates and drives the rack 9 to move, so that the movable frame 7 moves laterally relative to the slide 5.

[0021] The card push plate mechanism 30 includes a base 31, a primary push plate component and a secondary push plate component, the secondary push plate component is mounted on the base 31, the push plate platform 39 moves longitudinally on the secondary push plate component, and the primary push plate component is mounted on the push plate platform 39. The primary push plate component includes a push plate 40, a primary rack 36 mounted longitudinally on the push plate platform, a primary gear 35 meshing with the primary rack, and a primary driving shaft 34 driving the primary gear to rotate, the primary driving shaft 34 is driven by a motor, and the push plate 40 is mounted on the primary driving shaft 34 through a bearing. The secondary push plate component includes a secondary rack 37 mounted longitudinally on the base, a secondary gear 33 meshing with the secondary rack, and a secondary driving shaft 32 driving the secondary gear to rotate, the secondary driving shaft 32 is also driven by a motor, and the secondary driving shaft 32 is mounted on the push plate platform 39 through a bearing. The rotation of the secondary driving shaft 32 drives the secondary gear 33 to rotate and move on the secondary rack 37. The longitudinal movement of the secondary gear 33 means the longitudinal movement of the secondary driving shaft 32, that is, the longitudinal movement of the push plate platform 39 on the base; similarly, the rotation of the primary driving shaft 34 drives the primary gear 35 to rotate and move on the primary rack 36, that is, the push plate 40 moves longitudinally on the push plate platform 39, thereby pushing the card 11 on the push plate platform 39 to move forward. In order to improve the stability of the longitudinal movement, a guide component 38 can be provided. The present invention adopts a primary push plate component combined with a secondary push plate component, increases the stroke of the push plate 40 in a limited space, pushes the card 11 on the push plate platform 39 to the lifting platform 20 of the slitting machine, greatly reduces the size of the equipment, reduces the production cost, and is more convenient for the transportation and placement of the equipment.

[0022] When the machine is working, the card board 11 is stacked under the moving frame 7, and the lifting device drives the moving frame 7 to move down along the lifting guide rail 4 until the induction switch senses the piston rod of the double-rod cylinder, and the moving frame 7 stops moving down. At this time, the front plug-in board and the rear plug-in board correspond to the positions of the sockets of the highest card board, and the driving component drives the front plug-in board and the rear plug-in board to move toward each other, so that the plug-in board is inserted into the socket of the card board 11, and the lifting device drives the moving frame 7 to move up, so that the card board is separated from the next card board, and then the conveying device drives The movable frame 7 moves horizontally to the top of the push plate platform 39, and the lifting device moves down again until the card plate 11 is placed on the push plate platform 39. The driving component drives the front plug plate and the rear plug plate to move in the opposite direction and leave the card plate 11, and then the lifting device drives the movable frame 7 to reset; the card plate 11 on the push plate platform 39 is pushed longitudinally to the lifting platform 20 by the first-level push plate component and the second-level push plate component. After the pushing is completed, the first-level push plate component and the second-level push plate component respectively drive the push plate 40 and the push plate platform 39 to reset.
