[0021] The baler, belt conveyor, lifting mechanism, electric linear module, first cylinder, weighing sensor, second cylinder, third cylinder, fourth cylinder, fifth cylinder, X-axis drive module, Y-axis drive module, belt conveyor, and vacuum suction cup are all connected to an external controller.

[0022] In order to better achieve the purpose of the present invention, the present invention also provides a packaging method of a high-efficiency paper product packaging device, comprising the following steps:

[0023] Step 1: The output end of the second cylinder of the material blocking assembly moves upward to drive the telescopic plate to move upward, and the paper products to be packaged are transported to the upper plate of the weighing assembly through the belt conveyor on the rear side of the clamping and aligning assembly. The weighing sensor on the lower side of the upper plate detects the weight of the upper side of the upper plate in real time. When the weighing sensor detects that the weight of the paper products to be packaged reaches a preset value, it outputs an electrical signal to the external controller, and the external controller stops the belt conveyor on the rear side of the clamping and aligning assembly to continue conveying;

[0024] Step 2: The output end of the first cylinder of the clamping and aligning assembly moves to drive one of the sliding plates to move, the movement of one of the sliding plates drives the connecting rod thereon to move, the movement of the connecting rod drives the rotating plate to rotate, the rotation of the rotating plate drives another connecting rod to move, the movement of the other connecting rod drives another sliding plate to move, so that the two sliding plates move synchronously toward each other to align the front and back positions of the paper products to be packaged, the output end of the electric linear module of the pushing assembly moves to drive the vertical bracket to move, the movement of the vertical bracket drives the push plate to move, the push plate moves to align the left and right positions of the paper products to be packaged, the output end of the second cylinder of the blocking assembly moves downward to drive the telescopic plate to move downward, the telescopic plate moves downward to remove the blockage on the left side of the paper product to be packaged, and the push plate moves to push the paper product to be packaged to the baling machine position;

[0025] Multiple straight cardboards are stacked on the material storage rack, and the straight cardboards are transported to the position of the primary bending assembly on the inner side of the inner frame through two belt conveyors. The output end of the fifth cylinder of the primary bending assembly moves to drive the pressing plate to move, and press one end of the straight cardboard. The output end of the third cylinder of the primary bending assembly moves to drive the first bending plate to rotate 90 degrees on the rotating shaft base, and the straight cardboard is bent into an L-shaped cardboard. The output end of the fourth cylinder of the secondary bending assembly moves to drive the second bending plate to rotate 90 degrees on the first bending plate, and the L-shaped cardboard is bent into a C-shaped cardboard. The output end of the fifth cylinder moves to drive the pressing plate to move, and the pressed end of the straight cardboard is released. The two belt conveyors continue to transport the C-shaped cardboard to the inner frame and the outer frame close to the baler, and half of the C-shaped cardboard is moved out of the outer frame.

[0026] Step 3: The C-shaped cardboard is moved halfway out of the outer frame and close to the vacuum suction cup. The output end of the Y-axis drive module moves to drive the vacuum suction cup to be close to the position of the C-shaped cardboard outside the outer frame. The vacuum suction cup starts to suck one end of the C-shaped cardboard. The output end of the Y-axis drive module moves to drive the vacuum suction cup to move, and the C-shaped cardboard is moved to the packaging position of the baler. The lifting mechanism on the middle side of the baler lifts the stacked paper products to be packaged. The output end of the X-axis drive module moves to drive the Y-axis drive module to move. The Y-axis drive module moves to drive the vacuum suction cup to move. The vacuum suction cup moves and drives the C-shaped cardboard toward the lifted paper products to be packaged, so that the two C-shaped cardboards are moved to the front and back sides of the paper products to be packaged. The baler packages them, and the lifting mechanism on the middle side of the baler descends. The belt conveyor on the left side of the baler transports the packaged paper products to be packaged out of the baler.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention conveys the paper products to be packaged to the weighing component through the belt conveyor on the rear side of the clamping and aligning component. When the weighing component detects that the weight of the paper products to be packaged reaches a preset value, the external controller controls the clamping and aligning component to align the stacked paper products to be packaged in front-to-back direction, and the pushing component aligns the stacked paper products to be packaged in left-to-right direction. After the paper products to be packaged are aligned, the external controller controls the material blocking component to descend, and the pushing component pushes the paper products to be packaged to the baler position, thereby realizing quantitative stacking and alignment of the paper products to be packaged, which is beneficial to quantitative stacking and alignment of the paper products to be packaged in front-to-back, left-to-right and left-to-right directions. A plurality of straight cardboards are stacked on the material storage rack, and the straight cardboards are conveyed to the primary bending component on the middle side of the material guide component through the conveying component. The primary bending component bends the straight cardboard into an L-shaped cardboard, and then the secondary bending component bends the L-shaped cardboard into a C-shaped cardboard. The C-shaped cardboard is conveyed to the baler position through the conveying component, thereby realizing automatic folding of the straight cardboard.

[0028] The C-shaped cardboard is moved halfway out of the outer frame and close to the vacuum suction cup. The output end of the Y-axis drive module moves to drive the vacuum suction cup to be close to the position of the C-shaped cardboard outside the outer frame. The vacuum suction cup starts to suck one end of the C-shaped cardboard. The output end of the Y-axis drive module moves to drive the vacuum suction cup to move and move the C-shaped cardboard to the packaging position of the baler. Since the vacuum suction cup absorbs one end of the C-shaped cardboard, it does not affect the baler to pack to the vacuum suction cup. The lifting mechanism on the middle side of the baler lifts the stacked paper products to be packaged. The output end of the X-axis drive module moves to drive the Y-axis The driving module moves, and the Y-axis driving module moves to drive the vacuum suction cup to move. The vacuum suction cup moves to drive the C-shaped cardboard to move toward the lifted paper product to be packaged, so that the two C-shaped cardboards are moved to the front and rear sides of the paper product to be packaged, and the baler packages it. The two C-shaped cardboards are edge-wrapped to prevent the edges of the paper product to be packaged from being bruised or broken. The lifting mechanism on the middle side of the baler descends, and the belt conveyor on the left side of the baler conveys the packaged paper product to be packaged out of the baler, which is conducive to the continuous feeding of the C-shaped cardboard and automatically wraps the edges of the paper product to be packaged. The present invention can quantitatively stack and align the front, back, left and right directions of the paper product to be packaged, can fold the straight cardboard into a C-shaped cardboard, and automatically wrap the edges of the paper product to be packaged to prevent the edges of the paper product to be packaged from being torn by the strapping of the baler.

The output end of the fourth cylinder 101 of the secondary bending component 10 moves to drive the second bending plate 102 to rotate ninety degrees on the first bending plate 92, and the L-shaped cardboard is bent into a C-shaped cardboard 13. The output end of the fifth cylinder 94 moves to drive the pressing plate 95 to move, and releases the pressed end of the straight cardboard. The two belt conveyors 61 continue to transport the C-shaped cardboard 13 to the inner frame 81 and the outer frame 82 close to the baler 1. Half of the C-shaped cardboard 13 moves out of the outer frame 82, which is beneficial to the folding and transportation of the straight cardboard.

When the paper products to be packaged reach a certain number, the weighing sensor 42 on the lower side of the upper plate 41 detects the weight of the upper side of the upper plate 41 in real time. When the weighing sensor 42 detects that the weight of the paper products to be packaged reaches a preset value, it outputs an electrical signal to the external controller, and the external controller stops the belt conveyor on the rear side of the clamping and aligning assembly 3 to continue conveying;

[0073] Step 2: The output end of the first cylinder 32 of the clamping and aligning assembly 3 moves to drive one of the sliding plates 33 to move, and the movement of one of the sliding plates 33 drives the connecting rod 34 thereon to move, and the movement of the connecting rod 34 drives the rotating plate 35 to rotate, and the rotation of the rotating plate 35 drives the other connecting rod 34 to move, and the movement of the other connecting rod 34 drives the other sliding plate 33 to move, so that the two sliding plates 33 move synchronously toward each other to align the front and back positions of the paper products to be packaged, and the output end of the electric linear module 21 of the pushing assembly 2 moves to drive the vertical bracket 22 to move, and the movement of the vertical bracket 22 drives the push plate 23 to move, and the push plate 23 moves to align the left and right positions of the paper products to be packaged, and the output end of the second cylinder 53 of the blocking assembly 5 moves downward to drive the telescopic plate 51 to move downward, and the telescopic plate 51 moves downward to remove the blockage on the left side of the paper product to be packaged, and the push plate 23 moves to push the paper product to be packaged to the baling machine 1 position;

[0074] A plurality of straight cardboards are stacked on the material storage rack 7, and the straight cardboards are transported to the position of the primary bending assembly 9 on the middle side of the inner frame 81 through two belt conveyors 61. The output end of the fifth cylinder 94 of the primary bending assembly 9 moves to drive the pressing plate 95 to move, and press one end of the straight cardboard. The output end of the third cylinder 93 of the primary bending assembly 9 moves to drive the first bending plate 92 to rotate ninety degrees on the rotating shaft base 91, and the straight cardboard is bent into an L-shaped cardboard. The output end of the fourth cylinder 101 of the secondary bending assembly 10 moves to drive the second bending plate 102 to rotate ninety degrees on the first bending plate 92, and the L-shaped cardboard is bent into a C-shaped cardboard 13. The output end of the fifth cylinder 94 moves to drive the pressing plate 95 to move, and release the pressed end of the straight cardboard.

[0075] Step 3: The C-shaped paperboard 13 is moved halfway out of the outer frame 82 and close to the vacuum suction cup 111. The output end of the Y-axis driving module 113 moves to drive the vacuum suction cup 111 to be close to the position of the C-shaped paperboard 13 outside the outer frame 82. The vacuum suction cup 111 starts to suck one end of the C-shaped paperboard 13. The output end of the Y-axis driving module 113 moves to drive the vacuum suction cup 111 to move, and the C-shaped paperboard 13 is moved to the packaging position of the packaging machine 1. The lifting mechanism 12 on the middle side of the packaging machine 1 lifts the stacked paper products to be packaged.

[0077] When the weighing sensor 42 detects that the weight of the paper products to be packaged reaches a preset value, it outputs an electrical signal to the external controller, and the external controller controls the vertical drive module to start. The output end of the vertical drive module moves upward to drive the blocking plate 14 to move upward, and the paper products to be packaged on the belt conveyor on the rear side of the clamping and alignment component 3 are blocked. After the push plate 23 returns to the rightmost end, the output end of the vertical drive module moves downward to drive the blocking plate 14 to move downward, and the paper products to be packaged on the belt conveyor on the rear side of the clamping and alignment component 3 fall to the upper side of the upper side plate 41.
