[0046] Embodiment 1

[0047] like Figures 1 to 13 As shown, the palletizing device 100 provided in this embodiment is used for transporting a packaging box 200, and includes a mounting frame 10, a clamping device 20 and a sponge suction cup 40. The packaging box 200 is fixed by the clamping device 20 and the sponge suction cup 40 mounted on the mounting frame 10, so that the packaging box 200 can be moved together with the mounting frame 10. It should be noted that the above-mentioned palletizing device 100 can also be installed with only the clamping device 20, and the clamping device 20 can be used to clamp and release the packaging box 200 to achieve clamping and loosening of the packaging box 200; or only the sponge suction cup 40 can be installed, and the sponge suction cup 40 can be used to suck and loosen the packaging box 200 to achieve suction and loosening of the packaging box 200. Of course, if the clamping device 20 and the sponge suction cup 40 are installed at the same time, the clamping device 20 and the sponge suction cup 40 can also be used to grab the packaging box 200 according to the actual situation.

[0048] See also Figures 1 to 13 In the present embodiment, the packaging box 200 used as the transport object of the palletizing device 100 is a paper box in the shape of a rectangular parallelepiped and adapted to the shape of the air conditioner outdoor unit. The box may contain but is not limited to the air conditioner outdoor unit, and the palletizing device 100 may fix the packaging box 200 by means of a clamping device 20 and / or a sponge suction cup 40 installed on the mounting frame 10.

[0049] See also Figures 1 to 13 In this embodiment, the mounting frame 10 includes a length direction (the direction of the X-axis shown in the figure), a width direction (the direction of the Y-axis shown in the figure), and an up-down direction (the direction of the Z-axis shown in the figure). It should be noted that the length direction, width direction, and up-down direction of the mounting frame 10 correspond to the length direction, width direction, and height direction of the packaging box 200, respectively.

[0050] See also Figures 1 to 5The palletizing device 100 of the present embodiment includes a mounting frame 10 and a clamping device 20. The clamping device 20 includes two clamping mechanisms 30 that can move relative to each other along the length direction of the mounting frame 10. A clamping space 21 for clamping a packaging box 200 is formed between the two clamping mechanisms 30. Each clamping mechanism 30 includes a moving seat 31, a clamping plate 32, a connecting rod 33 and a maintaining assembly 34. The moving seat 31 can be movably arranged on the mounting frame 10 along the length direction of the mounting frame 10. The clamping plate 32 is used to abut against the packaging box 200. The connecting rod 33 has a first end 33a and a second end 33b opposite to each other. The first end 33a is hinged to the moving seat 31, and the second end 33b is hinged to the clamping plate 32. The maintaining assembly 34 is arranged on the moving seat 31 and is used to drive the clamping plate 32 to rotate around the first end 33a toward the clamping space 21. In this embodiment, two clamping mechanisms 30 are symmetrically arranged on the midline of the length direction of the mounting frame 10, and the clamping device 20 includes two clamping mechanisms 30 arranged side by side and spaced apart in the length direction of the mounting frame 10, and a clamping space 21 located below the mounting frame 10 is formed between the two clamping mechanisms 30, and the two clamping mechanisms 30 can move relatively along the length direction of the mounting frame 10 to clamp and release the packaging box 200. Each clamping mechanism 30 includes a moving seat 31, a clamping plate 32 and a maintaining assembly 34 are arranged on the moving seat 31 and supported by the moving seat 31, and the clamping plate 32 is used to abut against the side wall of the packaging box 200, and the moving seat 31 can move left and right in the length direction of the mounting frame 10 (the left and right direction shown in the figure, that is, the direction of the X axis), and when the moving seat 31 moves toward each other, the spacing between the two clamping plates 32 is reduced, thereby clamping the packaging box 200 from the left and right sides of the packaging box 200; otherwise, the packaging box 200 is released. The maintaining assembly 34 can drive the clamping plate 32 and the connecting rod 33 to rotate around the first end 33 a toward the clamping space 21 (ie, the other clamping mechanism 30 of the two clamping mechanisms 30 ).

[0051] The above-mentioned palletizing device 100 includes a clamping device 20, which includes two clamping mechanisms 30. Each clamping mechanism 30 includes a movable seat 31, a clamping plate 32, a connecting rod 33 and a maintaining assembly 34. The movable seat 31 can be movably arranged on the mounting frame 10 along the length direction of the mounting frame 10. The clamping plate 32 is used to abut against the packaging box 200. The first end 33a of the connecting rod 33 is hinged to the movable seat 31, and the second end 33b of the connecting rod 33 is hinged to the clamping plate 32. The maintaining assembly 34 is arranged on the movable seat 31 and is used to drive the clamping plate 32 to rotate around the first end 33a toward the clamping space 21. In this way, the opening and closing movement of the clamping device 20 is realized by the relative movement of the two clamping mechanisms 30. When the two clamping mechanisms 30 move toward each other, the clamping plates 32 are driven to respectively abut against the two sides of the packaging box 200 to clamp the packaging box 200. When the two clamping mechanisms 30 move in opposite directions, the clamping plates 32 are driven away from the packaging box 200 to release the packaging box 200, thereby realizing the clamping and release of the packaging box 200 by the stacking device 100. When the stacking device 100 encounters an unexpected sudden situation of power failure and / or gas failure, the clamping plate 32 can be driven around the first end by the maintaining component 34. 33a rotates toward the clamping space 21, that is, when the above situation occurs, the maintaining component 34 can provide a driving force for the clamping plate 32 to move toward the clamping space 21, and the clamping plates 32 of the two clamping mechanisms 30 can further form a clamping force to move toward the clamping space 21, thereby clamping the packaging box 200. In this way, when encountering an emergency situation of power outage and / or gas outage, the maintaining component 34 can be used to drive the clamping plate 32 to clamp the packaging box 200, so as to improve the stability and safety of the stacking device 100 in carrying the packaging box 200, and avoid the accident of the packaging box 200 falling.

[0052] Figures 2 to 4 The figure shows the working state of the clamping device 20 when the palletizing device 100 hides the sponge suction cup 40 .

[0053] See also Figures 2 to 4 In the clamping device 20 of this embodiment, the clamping mechanism 30 further includes a transverse driving member 35, which is fixed on the mounting frame 10 and connected to the moving seat 31 of the clamping mechanism 30. The transverse driving member 35 can drive the moving seat 31 to move along the length direction of the mounting frame 10. In this embodiment, the transverse driving member 35 is but not limited to a cylinder, which is fixedly mounted on the mounting frame 10 through a cylinder seat, and the output shaft of the transverse driving member 35 is connected and fixed to the moving seat 31, thereby pushing the moving seat 31 to move in the length direction of the mounting frame 10.

[0054] In other embodiments, the two clamping mechanisms 30 may share a transverse driving mechanism, that is, a transverse driving mechanism is provided on the mounting frame 10 and is respectively connected to the movable seats 31 in the two clamping mechanisms 30 to drive the two movable seats 31 to move. The transverse driving mechanism may be a pneumatic cylinder, an oil cylinder, an electric cylinder, a lead screw, etc.

[0055] See also Figures 2 to 9 The maintaining assembly 34 of this embodiment includes an operating rod 341, an elastic member 342 and a maintaining driving member 343. The operating rod 341 can be movably arranged between a first position 34a and a second position 34b in the up-down direction. The operating rod 341 is connected to the clamping plate 32 and can drive the clamping plate 32 to rotate around the first end 33a when the operating rod 341 moves in the up-down direction; the maintaining driving member 343 is used to keep the operating rod 341 in the first position 34a and deform the elastic member 342 to generate an elastic reset force that drives the operating rod 341 to move to the second position 34b. In this embodiment, the operating rod 341 can move up and down along the up and down direction (the up and down direction shown in the figure, i.e., the direction of the Z axis), and the operating rod 341 has a first position 34a (maintaining the output shaft of the driving member 343 is located at the position of the minimum stroke of the driving member 343) and a second position 34b (maintaining the output shaft of the driving member 343 is located at the position of the maximum stroke of the driving member 343) in the up and down direction, and the driving member 343 is maintained but not limited to a cylinder, and the driving member 343 is fixed on and supported by the moving seat 31, and the output shaft of the driving member 343 is connected to the operating rod 341, and the operating rod 341 can be driven to reciprocate between the first position 34a and the second position 34b. It should be noted that, in the process of carrying the packaging box 200 by the stacking device 100 of this embodiment, the operating rod 341 is maintained at the first position 34a by the driving member 343, and at this time, the operating rod 341 deforms the elastic member 342 to generate an elastic reset force that drives the operating rod 341 to move to the second position 34b. When the palletizing device 100 encounters an unexpected power outage and / or gas outage, the output shaft of the transverse drive member 35 and the output shaft of the maintaining drive member 343 can be kept in position unchanged by means of a gas outage protection gas circuit structure (not shown) provided in the gas circuit system. At the same time, the elastic restoring force of the elastic member 342 drives the operating rod 341 to drive the clamping plate 32 to generate a clamping force on the packaging box 200 to clamp the packaging box 200.

[0056] See also Figures 6 to 9 In the clamping mechanism 30 of this embodiment, the clamping plate 32 is located between the two movable seats 31, and the maintaining driving member 343 is arranged on the top of the movable seat 31, wherein the first position 34a is located above the second position 34b, and the connecting rod 33 extends upward from the movable seat 31 and obliquely toward the clamping space 21 to the clamping plate 32.

[0057] from Figures 6 to 9 It can be seen that in this embodiment, the moving seat 31 is mounted on the mounting frame 10 through a slider, and the driving member 343 is fixedly mounted on the top of the moving seat 31, and its output shaft extends downward and is connected to the top of the operating rod 341. The output shaft of the driving member 343 is basically coaxial with the operating rod 341, and the elastic member 342 is but not limited to a compression spring. The operating rod 341 is movably connected to the clamping plate 32. Under the drive of the driving member 343, the operating rod 341 can only move up and down. When the operating rod 341 moves up and down, it can drive the clamping plate 32 to rotate around the first end 33a. Under normal conditions, the output shaft of the driving member 343 is retracted to the minimum stroke, and the operating rod 341 is moved to the first position 34a, and the second end 33b is located above the first end 33a. At this time, the elastic member 342 is compressed and deformed to form an elastic reset force. When the palletizing device 100 encounters an unexpected power outage and / or gas outage, the driving member 343 is maintained to eliminate the pulling force on the operating rod 341. At this time, the elastic restoring force will push the operating rod 341 downward. Driven by the elastic member 342, the operating rod 341 provides a driving force for the clamping plate 32 to rotate downward around the first end 33a and toward the clamping space 21, thereby ensuring the clamping force of the clamping plate 32 on the packaging box 200 to clamp the packaging box 200.

[0058] In other embodiments, the positions of the driving member 343, the clamping plate 32 and the movable seat 31 are maintained unchanged, and the arrangement of the connecting rod 33, the movable seat 31 and the clamping plate 32 remains unchanged, wherein the elastic member 342 is but not limited to a tension spring, which is fixedly mounted on the bottom of the movable seat 31 and connected to the bottom end of the connecting rod 33. When the operating rod 341 is maintained at the first position 34a, the elastic member 342 is stretched and deformed to form an elastic restoring force, which can provide a driving force for the clamping plate 32 to rotate downward around the first end 33a and toward the clamping space 21 when the stacking device 100 encounters an unexpected emergency of power failure and / or gas failure.

[0059] See also Figures 6 to 9 In this embodiment, the movable seat 31 is provided with an assembly part 311, one end of the operating rod 341 passes through the assembly part 311 and is connected to the maintaining driving member 343, and the elastic member 342 is arranged between the operating rod 341 and the assembly part 311 in a compressed and deformed manner. In this embodiment, the upper end (the upper end shown in the figure) of the operating rod 341 extends into the assembly part 311 and is connected to the output shaft of the maintaining driving member 343, and the elastic member 342 is installed on the top of the operating rod 341 and abuts against the bottom surface of the assembly part 311. Under normal conditions, in the clamping mechanism 30 of the stacking device 100, the operating rod 341 is at the first position 34a and presses the elastic member 342. In this way, the installation of the elastic member 342 can be facilitated, and this structure can provide sufficient elastic reset force in the case of power failure / gas failure to ensure that the clamping plate 32 clamps the packaging box 200.

[0060] Particularly, a hole for the operating rod 341 to extend out is provided on the assembly portion 311 , and the assembly portion 311 can guide the operating rod 341 when the operating rod 341 moves, so as to guide the operation rod 341 to move.

[0061] See also Figures 6 to 9 In this embodiment, the clamping plate 32 is provided with an operation cooperation rod 321, which is connected to the operation rod 341 and can drive the clamping plate 32 to rotate around the first end 33a under the drive of the operation rod 341. In this embodiment, the clamping plate 32 is provided with an operation cooperation rod 321 on the top, which extends from the clamping plate 32 in a direction away from the clamping space 21, and the operation cooperation rod 321 is movably connected to the operation rod 341. When the operation rod 341 moves up and down, the operation cooperation rod 321 is driven to move upward and inward (toward the clamping space 21) or downward and outward (away from the clamping space 21).

[0062] See also Figures 6 to 9 The operation cooperation rod 321 of this embodiment is provided with a sliding groove 322, which extends outward from the middle of the operation cooperation rod 321 along the length direction of the mounting frame 10, and the operation rod 341 is inserted into the sliding groove 322 of the operation cooperation rod 321. It is easy to understand that the operation rod 341 is located in the middle of the operation cooperation rod 321, and when the operation cooperation rod 321 is driven to move, its driving force can act on the operation cooperation rod 321 more stably. In addition, the operation cooperation rod 321 can limit the operation rod 341 in the width direction of the mounting frame 10.

[0063] See also Figures 6 to 9 In this embodiment, at least one pair of rollers 344 are provided on the operating rod 341, and two rollers 344 of the pair of rollers 344 are arranged at intervals in the up-down direction, and form a guide channel for the operation matching rod 321 to be placed. In this embodiment, a pair of rollers 344 are provided on both sides of the operating rod 341, and the two rollers 344 located on the same side of the operating rod 341 are respectively against the upper and lower surfaces of the operation matching rod 321, so that the operating rod 341 contacts the operation matching rod 321 through the rollers 344, and the rolling type is adopted to reduce the wear between the two when the two move relative to each other.

[0064] See also Figures 6 to 9The movable seat 31 of this embodiment has two cantilevers 312 which are parallel to each other and spaced apart. The maintaining assembly 34 is located between the two cantilevers 312. Each cantilever 312 is connected to the clamping plate 32 via a connecting rod 33. The two cantilevers 312 are spaced apart in the width direction of the mounting frame 10. Both sides of the clamping plate 32 are connected to the cantilevers 312 via the connecting rod 33. It is easy to understand that under the drive of the operating rod 341, the clamping plate 32 drives the connecting rod 33 to rotate relative to the cantilever 312.

[0065] See also Figures 6 to 9 , the number of connecting rods 33 disposed between each cantilever 312 and the clamping plate 32 is four, and the four connecting rods 33 are divided into two connecting rod groups 330 in pairs; the two connecting rod groups 330 are arranged at intervals along the up-down direction, and the connecting rods 33 in each connecting rod group 330 are respectively located on opposite sides of the cantilever 312 and are parallel to each other, and the connecting rods 33 in one of the two connecting rod groups 330 are arranged in parallel with the connecting rods 33 in the other group. In this embodiment, two connecting rod groups 330 are disposed between each side of the clamping plate 32 and the corresponding cantilever 312, and the two connecting rods 33 in each connecting rod group 330 are respectively connected to the two sides of the cantilever 312. In the clamping mechanism 30, the connecting rods 33 of the four connecting rod groups 330 are substantially parallel, and the first end 33a of each connecting rod 33 is pivotally attached to the movable seat 31 and the second end 33b is pivotally attached to the clamping plate 32 through a pivot, and the pivot extends along the width direction of the mounting frame 10. It can be understood that each side of the clamping plate 32 is connected to the cantilever 312 of the movable seat 31 through two sets of parallel connecting rod groups 330, and the clamping plate 32, the cantilever 312, and the connecting rod group 330 constitute a parallelogram mechanism. In this way, when the clamping plate 32 rotates relative to the cantilever 312, the rotation of the clamping plate 32 is more stable, and the inclination angle of the clamping plate 32 will not change during the rotation of the clamping plate 32 around the movable seat 31, so that the clamping plate 32 remains parallel to the side wall surface of the packaging box 200 during the rotation.

[0066] See also Figures 6 to 9 The size of the clamping plate 32 of this embodiment can be adjusted according to the volume of the packaging box 200.

[0067] See also Figures 6 to 9 In this embodiment, an elastic anti-skid pad 36 is provided on the clamping plate 32 to abut against the packaging box 200.

[0068] See also Fig.10 and 11 In the palletizing device 100 of the present embodiment, a sponge suction cup 40 is installed on the mounting frame 10. The sponge suction cup 40 includes a suction cup body 41 having an adsorption surface 411 and an adsorption sponge layer 42 installed on the adsorption surface 411 of the suction cup body 41. A buffer mechanism 50 is provided between the suction cup body 41 and the mounting frame 10.

[0069] The palletizing device 100 of the present embodiment adopts a sponge suction cup 40, which includes a suction cup body 41 and an adsorption sponge layer 42 installed on the suction cup body 41. A buffer mechanism 50 is provided between the suction cup body 41 and the mounting frame 10. In this way, during the process of the palletizing device 100 transporting the packaging box 200, the buffer mechanism 50 can reduce the collision between the sponge suction cup 40 when it contacts the packaging box 200. In addition, the sponge suction cup 40 can fully contact the surface of the packaging box 200, and the adsorption surface 411 of the sponge suction cup 40 on the packaging box 200 is larger, thereby improving the reliability of adsorption.

[0070] See also Fig.10 and 11 In this embodiment, the number of the sponge suction cups 40 is but not limited to two. Each sponge suction cup 40 extends along the length direction of the mounting frame 10. The length dimension of the sponge suction cup 40 is slightly larger than the length dimension of the packaging box 200. The two sponge suction cups 40 are arranged side by side in the width direction of the mounting frame 10. The sponge suction cup 40 includes a suction cup body 41 and an adsorption sponge layer 42. The suction cup body 41 is made of aluminum profile. The suction cup body 41 has an adsorption surface 411 located on its bottom surface. The adsorption surface 411 of the suction cup body 41 is provided with a plurality of ventilation holes (not shown in the figure). The size of the adsorption sponge layer 42 is adapted to the adsorption surface 411. The adsorption sponge layer 42 is provided with through holes corresponding to the ventilation holes (not shown in the figure). In this way, the structure of the sponge suction cup 40 is relatively hard and the maintenance cost is low. It is worth mentioning that during the transportation of the packaging box 200, the packaging box 200 can be adsorbed only by the sponge suction cup 40, and there is no need for the clamping device 20 to clamp it. Of course, if the sponge suction cup 40 and the clamping device 20 are used for transportation at the same time, the transportation safety can be greatly improved.

[0071] In particular, the number and size of the sponge suction cups 40 can be selected according to the size of the packaging box 200 .

[0072] In particular, the distance between adjacent sponge suction cups 40 can be selected according to the size of the packaging box 200 .

[0073] In particular, the sponge suction cup 40 may also be of a shorter length, and a plurality of sponge suction cups 40 may be disposed in the length direction of the mounting frame 10 .

[0074] See also Fig.10 and 11In this embodiment, the buffer mechanism 50 includes an upper receiving plate 51 connected to the mounting frame 10, a lower receiving plate 52 connected to the sponge suction cup 40, and a buffer assembly 53 arranged between the upper receiving plate 51 and the lower receiving plate 52; the buffer assembly 53 includes an upper spring assembly block 531, a lower spring assembly block 532 and a buffer spring 533, the upper spring assembly block 531 is fixed on the upper receiving plate 51, and the lower spring assembly block 532 is fixed on the lower receiving plate 52; one end of the buffer spring 533 is installed on the upper spring assembly block 531, and the other end is installed on the lower spring assembly block 532.

The upper receiving plate 51 in each buffer mechanism 50 is fixedly mounted on the mounting frame 10 by fasteners such as screws, and the lower receiving plate 52 is respectively connected and fixed to the suction cup bodies 41 of the two sponge suction cups 40 by fasteners such as screws. The number of buffer components 53 in each buffer mechanism 50 is but not limited to two. The two buffer components 53 are arranged side by side in the width direction of the mounting frame 10 and correspond to the two sponge suction cups 40 respectively. The upper spring assembly block 531 of the buffer component 53 is fixed to the upper receiving plate 51 by fasteners such as screws, and the lower spring assembly block 532 is fixed to the lower receiving plate 52 by fasteners such as screws; the buffer spring 533 is a compression spring, one end of the buffer spring 533 is installed on the upper spring assembly block 531, and the other end is installed on the lower spring assembly block 532. It can be understood that when the sponge suction cup 40 contacts the packaging box 200, the buffer spring 533 installed between the upper receiving plate 51 and the lower receiving plate 52 is compressed and deformed to provide buffering when the sponge suction cup 40 contacts the packaging box 200.

The two guide assemblies 54 are arranged side by side in the width direction of the mounting frame 10 and correspond to the two sponge suction cups 40 respectively. The buffer assembly 53 is located between the two guide assemblies 54. The guide sleeve 542 is fixed to the upper supporting plate 51 by fasteners such as screws, and partially passes through the upper supporting plate 51 and extends into the mounting frame 10. The bottom end of the guide column 541 is fixedly mounted on the lower supporting plate 52, and the top end extends out of the mounting frame 10 after passing through the guide sleeve 542. In this way, the movement of the sponge suction cup 40 relative to the mounting frame 10 can be guided by the guide assembly 54 composed of the guide column 541 and the guide sleeve 542.

[0076] See also Fig.10 and 11 In this embodiment, a limit cover 543 is provided at the other end of the guide column 541 opposite to the end connected to the lower receiving plate 52, so as to limit the downward movement of the guide column 541. In this embodiment, a limit cover 543 is provided at the top of the guide column 541, and the limit cover 543 is fixed to the guide column 541 by fasteners such as screws.

[0077] See also Fig.10 and 11 In this embodiment, a buffer gasket 544 is provided on the mounting frame 10 to abut against the limit cover 543. The buffer gasket 544 is but not limited to a silicone pad, which is sleeved on the guide column 541.

[0079] The palletizing system 1000 of this embodiment adopts the above-mentioned palletizing device 100 , which can prevent the packaging box 200 from accidentally falling during transportation, thereby improving the safety of transportation of the packaging box 200 .

[0080] Embodiment 2

[0081] See also Fig.14In the clamping mechanism 30 of this embodiment, the clamping plate 32 is located between the two moving seats 31, and the maintaining driving member 343 is arranged at the bottom of the moving seat 31, wherein the first position 34a is located below the second position 34b, and the connecting rod 33 extends downward from the moving seat 31 and obliquely toward the clamping space 21 to the clamping plate 32. In this embodiment, the moving seat 31 is mounted on the mounting frame 10 through a slider, and the maintaining driving member 343 is fixedly mounted at the bottom of the moving seat 31, and its output shaft extends upward and is connected to the bottom of the operating rod 341, and the output shaft of the maintaining driving member 343 is substantially coaxial with the operating rod 341, and the elastic member 342 is but not limited to a compression spring. The operating rod 341 is movably connected to the clamping plate 32, and under the drive of the maintaining driving member 343, the operating rod 341 can only move up and down, and when the operating rod 341 moves up and down, it can drive the clamping plate 32 to rotate around the first end 33a. Under normal conditions, the output shaft of the driving member 343 is retracted to the minimum stroke, and the operating rod 341 is moved to the first position 34a, and the second end 33b is located below the first end 33a. At this time, the elastic member 342 is compressed and deformed to form an elastic reset force. When the palletizing device 100 encounters an unexpected sudden situation of power failure and / or gas failure, the pulling force of the driving member 343 on the operating rod 341 is eliminated. At this time, the elastic reset force will push the operating rod 341 upward. Under the drive of the elastic member 342, the operating rod 341 provides the clamping plate 32 with a driving force to rotate upward around the first end 33a and toward the clamping space 21, thereby ensuring the clamping force of the clamping plate 32 on the packaging box 200 to clamp the packaging box 200.

The operating rod 341 is movably connected to the clamping plate 32, and under the drive of the maintaining driving member 343, the operating rod 341 can only move up and down, and when the operating rod 341 moves up and down, it can drive the clamping plate 32 to rotate around the first end 33a. Under normal conditions, the output shaft of the driving member 343 is retracted to the minimum stroke, and the operating rod 341 is moved to the first position 34a, and the second end 33b is located below the first end 33a. At this time, the elastic member 342 is compressed and deformed to form an elastic reset force.

At this time, the elastic reset force will push the operating rod 341 downward. Driven by the elastic member 342, the operating rod 341 provides the clamping plate 32 with a driving force to rotate downward around the first end 33a and toward the clamping space 21, thereby ensuring the clamping force of the clamping plate 32 on the packaging box body 200 to clamp the packaging box body 200.

[0085] In other embodiments, the positions of the driving member 343, the clamping plate 32 and the movable seat 31 are maintained unchanged, and the arrangement of the connecting rod 33, the movable seat 31 and the clamping plate 32 remains unchanged, wherein the elastic member 342 is but not limited to a tension spring, which is fixedly mounted on the top of the movable seat 31 and connected to the top end of the connecting rod 33. When the operating rod 341 is maintained at the first position 34a, the elastic member 342 is stretched and deformed to form an elastic restoring force, which can provide a driving force for the clamping plate 32 to rotate downward around the first end 33a and toward the clamping space 21 when the stacking device 100 encounters an unexpected emergency of power failure and / or gas failure.
