[0015] A method for using a stacking device for carton processing, the method comprising the following steps: A. When stacking is required during the carton processing, first, the first motor is started to drive the first bevel gear to rotate, and the rotation of the first bevel gear drives the second bevel gear and the first rotating sleeve to rotate, and the first rotating sleeve can move forward along the surface of the first screw. When the first rotating sleeve moves, it can drive the support frame and the stacking frame to move until the left opening of the stacking frame at the rear can be on the right side of the belt conveyor, and under the action of the subsequent belt conveyor, the cartons transported at the top can fall and be stacked inside the stacking frame, thereby achieving the effect of automatic stacking of cartons; B. Subsequently, when the cartons on one side of the stacking frame are stacked, the first motor is started again to drive the first bevel gear, the second bevel gear and the first rotating sleeve to rotate in the other direction respectively, so that the first rotating sleeve can move backward along the surface of the first screw under the action of rotation. The movement of the first rotating sleeve can drive the support frame and the stacking frame to move until the opening at the front of the left side of the stacking frame can be located on the right side of the belt conveyor, so as to continue to stack the cartons transported on the top of the belt conveyor; C. At the same time, when the stacking frame moves backward, it can drive the fixed cylinder, the moving frame and the magnetic control switch to move, so that the magnetic control switch at the rear can be located above the magnetic plate under the action of movement, and the contact inside the magnetic control switch can be closed under the action of magnetic force adsorption of the magnetic plate, so that the circuit of the electromagnetic valve at the rear can be connected, and the inside of the electromagnetic valve can be opened; D. Then, when the personnel starts the second motor, the first circular gear can be driven to rotate, and the rotation of the first circular gear can drive the second circular gear and the second rotating sleeve to rotate, so that the second rotating sleeve can drive the second screw and the first piston to move downward under the action of rotation. While the first piston moves, it can compress the air in the inner cavity of the pressurized box, so that the air inside the pressurized box can be transported to the inside of the air guide tube at the rear through the air guide pipe and the solenoid valve at the rear. Under the action of continuous air transportation, the second piston, the push rod and the limit clamping plate can be effectively pushed to move, so that the two sets of limit clamping plates at the rear can push the two sides of the cartons stacked in the stacking frame under the action of movement, so that the cartons with uneven edges can be leveled under the action of pushing; E. When the edges of the cartons are neatly stacked, the operator can start the second motor to drive the first circular gear, the second circular gear and the second rotating sleeve to rotate in the other direction, and enable the second screw and the first piston to move upward along the inner cavity of the second rotating sleeve and the pressurizing box respectively. Under the action of the movement of the first piston, the air in the inner cavity of the air guide cylinder can be drawn into the pressurizing box, while the second piston, the push rod and the limit clamp can move and detach from the surface of the cartons after stacking. Then the operator can use forklifts and other equipment to take out the cartons inside the stacking frame, thereby completing the stacking operation of the cartons.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention facilitates the effective stacking operation of the cartons transported on the top of the belt conveyor through the arrangement of the stacking platform, the stacking frame, the supporting frame, the first motor, the first bevel gear, the second bevel gear, the first rotating sleeve and the first screw, and can quickly switch the position of the stacking frame after the cartons on one side are stacked, effectively ensuring that the stacking operation can be stably and continuously operated, thereby ensuring the efficiency of the overall operation. At the same time, through the arrangement of the fixed cylinder, the movable frame, the magnetic control switch, the magnetic plate, the solenoid valve, the pressurizing box, the second motor, the first circular gear, the second circular gear, the second rotating sleeve, the second screw, the first piston, the air guide pipe, the air guide pipe, the second piston, the push rod and the limiting clamping plate, after the stacking frame completes the position switching, the limiting clamping plate in the corresponding position can be driven to move, and the limiting clamping plate can effectively level the side of the cartons after the stacking is completed under the action of the movement, effectively avoiding the side of the carton from tipping over during the subsequent transportation and transfer due to uneven stacking, thereby greatly improving the quality of the carton stacking operation.

[0017] The present invention can support the right end of the belt conveyor through the arrangement of the supporting legs. At the same time, through the arrangement of the limit frame, the L-shaped card plate, the threaded sleeve and the third screw rod, the two groups of third screw rods and the L-shaped card plate can be driven to move to the side away from each other under the action of a person operating the threaded sleeve for rotation, so that the L-shaped card plate can be tightly attached to the surface of the supporting leg under the action of movement, thereby effectively limiting and fixing the stacking platform and the belt conveyor, avoiding the position offset between the stacking platform and the belt conveyor and affecting the stacking effect of the cartons. The purpose of limiting and guiding the L-shaped card plate is achieved through the arrangement of the limit guide groove, avoiding the L-shaped card plate from rotating and tilting during the movement. The arrangement of the rotating rod makes it convenient for a person to operate the threaded sleeve for rotation.

[0018] The present invention can support the top and bottom of the mobile frame respectively through the arrangement of the support spring and the movable wheel, ensure that the mobile frame and the magnetic control switch can always maintain a suitable distance with the stacking platform, and effectively avoid the contact between the magnetic control switch and the stacking platform to cause wear, and achieve the purpose of limiting and guiding the mobile frame through the arrangement of the limit rod, and avoid the mobile frame from rotating and tilting during the movement, and achieve the purpose of guiding the second screw and the first piston through the arrangement of the L-shaped guide rod, and avoid the second screw and the first piston from rotating during the movement, and effectively improve the sealing of the contact between the first piston and the pressurizing box, and the second piston and the air guide cylinder through the arrangement of the first sealing ring and the second sealing ring, respectively, and achieve the purpose of supporting and guiding the limit clamping plate and the support frame through the arrangement of the guide slide bar and the support slide bar, and avoid the limit clamping plate and the support frame from tilting during the movement, and achieve the purpose of supporting and fixing both sides of the first screw through the arrangement of the support plate, and facilitate the fork arm of the forklift to be accommodated through the arrangement of the fork slot, so that personnel can use the forklift to take out the cartons stacked inside the stacking frame.

When stacking is required during the carton processing, first, the first motor 25 is started to drive the first bevel gear 26 to rotate, and the first bevel gear 26 rotates to drive the second bevel gear 28 and the first rotating sleeve 27 to rotate, and the first rotating sleeve 27 can move forward along the surface of the first screw 17. When the first rotating sleeve 27 moves, it can drive the support frame 18 and the stacking frame 8 to move until the left opening of the stacking frame 8 at the rear can be on the right side of the belt conveyor 1, and under the action of the subsequent operation of the belt conveyor 1, the cartons transported at the top can fall and be stacked inside the stacking frame 8, thereby achieving the effect of automatic stacking of the cartons; B. Subsequently, when the cartons on one side of the stacking frame 8 are stacked, the first motor 25 is started again to drive the first bevel gear 26, the second bevel gear 28 and the first rotating sleeve 27 to rotate in the other direction respectively, so that the first rotating sleeve 27 can move backward along the surface of the first screw 17 under the action of rotation. The movement of the first rotating sleeve 27 can drive the support frame 18 and the stacking frame 8 to move until the opening at the front of the left side of the stacking frame 8 can be located on the right side of the belt conveyor 1, so as to continue to stack the cartons transported on the top of the belt conveyor 1; C. At the same time, when the stacking frame 8 moves backward, it can drive the fixed cylinder 19, the moving frame 22 and the magnetic control switch 24 to move, so that the magnetic control switch 24 at the rear can be located above the magnetic plate 10 under the action of movement, and the contact inside the magnetic control switch 24 can be closed under the action of magnetic attraction of the magnetic plate 10, so that the circuit of the electromagnetic valve 12 at the rear can be connected, and the interior of the electromagnetic valve 12 can be opened; D. Then, when the second motor 31 is started by a person, the first circular gear 32 can be driven to rotate. The rotation of the first circular gear 32 can drive the second circular gear 35 and the second rotating sleeve 36 to rotate, so that the second rotating sleeve 36 can drive the second screw 42 and the first piston 34 to move downward under the action of rotation. While the first piston 34 moves, it can compress the air in the inner cavity of the pressurized box 13, so that the air inside the pressurized box 13 can be transported to the inside of the air guide tube 6 at the rear through the air guide pipe 4 and the solenoid valve 12 at the rear. Under the action of continuous air transportation, the second piston 41, the push rod 30 and the limiting clamping plate 7 can be effectively pushed to move, so that the two groups of limiting clamping plates 7 at the rear can push the two sides of the cartons stacked in the stacking frame 8 under the action of movement, so that the cartons with uneven edges can be leveled under the action of pushing; E. When the edges of the cartons are neatly stacked, the operator can start the second motor 31 to drive the first circular gear 32, the second circular gear 35 and the second rotating sleeve 36 to rotate in the other direction, and enable the second screw 42 and the first piston 34 to move upward along the second rotating sleeve 36 and the inner cavity of the pressurizing box 13 respectively. Under the action of the movement of the first piston 34, the air in the inner cavity of the air guide cylinder 6 can be drawn into the pressurizing box 13, while the second piston 41, the push rod 30 and the limiting clamp 7 can move and detach from the surface of the cartons after stacking. Then the operator can use a forklift or other equipment to take out the cartons in the stacking frame 8, thereby completing the stacking operation of the cartons.

10. A method for using a stacking device for carton processing according to any one of claims 1 to 9, characterized in that: The method of use comprises the following steps: A. When stacking is required during the carton processing, first, the first motor (25) is started to drive the first bevel gear (26) to rotate. The rotation of the first bevel gear (26) drives the second bevel gear (28) and the first rotating sleeve (27) to rotate, and the first rotating sleeve (27) is moved forward along the surface of the first screw (17). When the first rotating sleeve (27) moves, it can drive the support frame (18) and the stacking frame (8) to move until the left opening of the stacking frame (8) at the rear is on the right side of the belt conveyor (1). Under the action of the subsequent operation of the belt conveyor (1), the cartons transported at the top can fall down and be stacked inside the stacking frame (8), thereby achieving the effect of automatically stacking the cartons; B. Subsequently, when the cartons on one side of the stacking frame (8) are stacked, the first motor (25) is started again to drive the first bevel gear (26), the second bevel gear (28) and the first rotating sleeve (27) to rotate in the other direction, so that the first rotating sleeve (27) can move backward along the surface of the first screw (17) under the action of rotation. The movement of the first rotating sleeve (27) can drive the support frame (18) and the stacking frame (8) to move until the opening at the front of the left side of the stacking frame (8) can be located on the right side of the belt conveyor (1), so as to continue to stack the cartons transported on the top of the belt conveyor (1); C. At the same time, when the stacking frame (8) moves backward, it can drive the fixed cylinder (19), the movable frame (22) and the magnetic control switch (24) to move, so that the magnetic control switch (24) at the rear can be located above the magnetic plate (10) under the action of movement, and the contact inside the magnetic control switch (24) can be closed under the action of magnetic attraction of the magnetic plate (10), so that the circuit of the electromagnetic valve (12) at the rear can be connected, and the interior of the electromagnetic valve (12) can be opened; D. Then, when the second motor (31) is started by a person, the first circular gear (32) can be driven to rotate. The rotation of the first circular gear (32) can drive the second circular gear (35) and the second rotating sleeve (36) to rotate, so that the second rotating sleeve (36) can drive the second screw (42) and the first piston (34) to move downward under the action of rotation. While the first piston (34) moves, it can compress the air in the inner cavity of the pressurizing box (13), so that the air inside the pressurizing box (13) can be transported to the inside of the air guide cylinder (6) at the rear through the air guide pipe (4) and the solenoid valve (12) at the rear. Under the action of continuous air transportation, the second piston (41), the push rod (30) and the limit clamp (7) can be effectively pushed to move, so that the two sets of limit clamps (7) at the rear can push the two sides of the cartons stacked inside the stacking frame (8) under the action of movement, so that the cartons with uneven edges can be leveled under the action of pushing; E. When the edges of the cartons are neatly stacked, the personnel can start the second motor (31) to drive the first circular gear (32), the second circular gear (35) and the second rotating sleeve (36) to rotate in the other direction, and enable the second screw (42) and the first piston (34) to move upward along the inner cavity of the second rotating sleeve (36) and the pressurizing box (13) respectively. Under the action of the movement of the first piston (34), the air in the inner cavity of the air guide cylinder (6) can be sucked into the interior of the pressurizing box (13), and the second piston (41), the push rod (30) and the limit clamp (7) can move and detach from the surface of the cartons after stacking. Then, the personnel can use a forklift or other equipment to take out the cartons in the stacking frame (8), thereby completing the stacking operation of the cartons.
