[0039] Reference Figure 3-Figure 5 A carton opening machine of the present embodiment includes a frame 1, and a material shifting mechanism 2, a box opening mechanism 3 and a box folding mechanism 4 arranged on the frame 1. A storage area 11 is provided on the frame 1 for storing paper boxes 6 to be unfolded. The material shifting mechanism 2 is used to take out the paper boxes 6 to be unfolded from the material storage rack and transfer them to the box opening position 12. The box opening mechanism 3 is used to open the paper box 6 located at the box opening position 12 to make it fully open. The box folding mechanism 4 is used to fold the rear end of the paper box 6 in the fully open state to close the opening of the rear end.

[0040] Reference Figure 1 , Figure 4 and Figure 5 The frame 1 has two receiving frames 13, which are arranged along the X-axis direction. The two receiving frames 13 are arranged opposite to each other. A notch 131 is formed on the receiving frame 13, and the two notches 131 form a box opening position 12. The left and right side walls of the notch 131 are arranged in an arc-shaped expansion shape. The storage area 11 is located directly above one end of the receiving frame 13 in the length direction. The storage area 11 is provided with a stacking and sorting mechanism, which includes a plurality of limiting angle steels 14. The plurality of limiting angle steels 14 are fixedly arranged on the frame 1. The flat paper boxes 6 are stacked on the two receiving frames 13. The plurality of limiting angle steels 14 surround the paper boxes 6 and limit the flat paper boxes 6. A gap is left between the bottom surface of the limiting angle steel 14 and the top surface of the receiving frame 13 for only one flat paper box 6 to move out.

[0041] Reference Figure 1 and Figure 5 The material transfer mechanism 2 includes an adsorption component and a driving component. The adsorption component is used to adsorb the bottom surface of the box body 61. The driving component drives the adsorption component to move to the top of the box opening position 12 and downward into the box opening position 12. The adsorption component includes a receiving plate 21, a pressure control device and a plurality of suction cups 22. The receiving plate 21 is movably connected to the frame 1. The plurality of suction cups 22 are detachably connected to the receiving plate 21. The pressure control device is used to control the air pressure inside the suction cups 22. The plurality of suction cups 22 are located below the box body 61 to adsorb one side of the box body 61. The pressure control device is used to control the suction cups 22 to adsorb the paper box 6 and put down the paper box 6. The driving component drives the paper box 6 to move by driving the receiving plate 21 to move.

[0042] Reference Figure 5 The driving assembly includes an X-axis slide 23 and a sixth cylinder 24. The X-axis slide 23 is slidably connected to the frame 1 along the X-axis direction by the drive of the motor screw, the X-axis slide 23 is located between the two receiving frames 13, and the sixth cylinder 24 is fixedly arranged on the X-axis slide 23, and the piston rod of the sixth cylinder 24 is vertically arranged upward and fixed on the receiving plate 21.

[0043] Reference Figure 4 and 5 After the suction assembly moves to the bottom of the stacked paper boxes 6 and suctions the bottom paper box 6, it can be moved out of the stacking and sorting mechanism through the gap, while the remaining paper boxes 6 cannot be moved out due to the blocking of the limit lever, so that the paper boxes 6 are moved out one by one. When the suction assembly moves the flat paper box 6 to the top of the notch 131, the piston rod of the sixth cylinder 24 contracts, and the paper box 6 is located at the opening position 12 in the notch 131.

[0044] Reference Figure 6 and Figure 7The box opening mechanism 3 includes two clamping assemblies respectively arranged on the left and right sides of the box opening position 12, and the clamping assemblies include a second driving member 31 and a stopper 32. The two stoppers 32 are respectively located on the left and right sides of the box opening position 12, and the second driving member 31 is used to drive the two stoppers 32 to abut against the left and right sides of the box body 61. The paper box 6 can be opened under the action of the two stoppers 32, and the two stoppers 32 are respectively abutted on the two opposite side surfaces of the box body 61, which can play a clamping and positioning role on the opened box body 61, so that the paper box 6 remains in the open box state.

[0045] Reference Figure 6-Figure 8 The box opening mechanism 3 further includes a third driving member 33 and an auxiliary top block 34. The third driving member 33 is located at one side of the rear end of the paper box 6. The third driving member 33 is used to drive the auxiliary top block 34 to move in the vertical direction. The auxiliary top block 34 is used to move to a preset position to assist the paper box 6 in being in a half-open state. The auxiliary top block 34 is L-shaped. The auxiliary top block 34 in the preset position state can lift the base tongue 62, the buckle or the side tongue 64 located at the non-overlapping part of the upper layer.

[0046] Reference Figure 6-Figure 8 Since the paper box 6 in the flat state to be unfolded may be pressed relatively tightly, if the two push blocks 32 are directly used to open the paper box 6, the entire flat paper box 6 may be folded. Therefore, the upper part of the paper box 6 is lifted up by the auxiliary push block 34, so that the upper and lower layers of the flat paper box 6 are separated first, which can assist the two push blocks 32 to open the box.

[0047] Reference Figure 6 and Figure 7 The frame 1 is provided with a stabilizing assembly 5, which includes a first driving member 51 and a stopper 52. The first driving member 51 is used to push the stopper 52 and abut against the front end of the box body 61 before the folding mechanism 4 folds the box. Since the two side tongues 64 at one end of the opening are always erected and located at the same position after the paper box 6 is erected, the paper box 6 can be placed upright or in reverse, as long as the rear end of the paper box 6 faces the right direction, the stopper 52 can act on the box body 61 to prevent the paper box 6 from retreating when the folding mechanism 4 acts, thereby improving the freedom of placing the paper box 6.

[0048] Reference Figure 6 and Figure 7 The stopper 52 is located on the left side of the folding position, and the front end of the stopper 52 is arranged in an arc shape toward the side away from the box body 61. Before folding the box, during the process of the stopper 52 moving toward the side of the paper box 6, the end close to the paper box 6 will first abut against the corresponding side tongue 64 at the opening end of the paper box 6, and then gradually fold the side tongue 64 inward, and finally abut against the box body 61, which can prevent the stopper 52 from directly abutting and pushing the box body 61.

[0049] Reference Figure 6 and Figure 7The stabilizing assembly 5 further includes a fourth driving member 53, a first limit block 54 and a second limit block 55. The first driving member 51 and the fourth driving member 53 are respectively located on the left and right sides of the box opening position 12. The first driving member 51 is used to drive the first limit block 54 to move, and the fourth driving member 53 is used to drive the second limit block 55 to move. The first limit block 54 and the second limit block 55 are used to synchronously abut against the side walls of the paper box 6 during the box opening process.

[0050] Reference Figure 6 and Figure 7 The two stoppers 32 are used to clamp the rear end of the paper box 6, and the first limit block 54 and the second limit block 55 are used to clamp the front end of the paper box 6. Both ends of the paper box 6 are restricted, further improving the stability of the paper box 6 during the folding operation.

[0051] Reference Figure 6 and Figure 7 The stabilizing assembly 5 further includes a fifth driving member 56 and a pressing rod 57. The fifth driving member 56 is disposed on the frame 1. The fifth driving member 56 is used to drive the pressing rod 57 to move in the vertical direction. The pressing rod 57 is located above the paper box 6. The pressing rod 57 is used to press the top surface of the box body 61 after the box is opened. The pressing rod 57 limits the movement of the paper box 6 in the vertical direction, further improving the stability of the paper box 6.

[0052] Reference Figure 4 The box folding mechanism 4 includes a base tongue 62 folding mechanism, a buckle tongue 63 folding mechanism and two side tongue 64 folding mechanisms. After the paper box 6 is opened and the stabilizing assembly 5 limits the paper box 6, the base tongue 62 folding mechanism is used to fold the base tongue 62, and then the two side tongue 64 folding mechanisms fold the two side tongues 64 respectively, and finally the buckle tongue 63 folding mechanism is used to fold the buckle tongue 63.

[0053] Reference Figure 1 , Figure 2 and Figure 4 The folding mechanism of the base tongue 62 includes a seventh cylinder 41, a first seat 42, an eighth cylinder 43 and a base push plate 44. The seventh cylinder 41 is fixed on the frame 1. The piston rod of the seventh cylinder 41 is vertically arranged upward and fixed on the first seat 42. The eighth cylinder 43 is fixed on the first seat 42. The piston rod of the eighth cylinder 43 is inclined upward toward one side of the paper box 6. The base push plate 44 is fixed on the piston rod of the eighth cylinder 43. The base push plate 44 is used to abut against the base tongue 62 and fold the base tongue 62. Since the base push plate 44 pushes the base tongue 62 from the oblique side, the base push plate 44 can act on the base tongue 62 to fold the base tongue 62 within the normal opening angle, thereby improving the applicability of the folding mechanism of the base tongue 62 to paper boxes 6 in different states.

[0054] Reference Figure 1 , Figure 2 and Figure 4 The folding mechanism of the side tongue 64 includes a second seat 45, a ninth cylinder 46, a side push plate 47 and a tenth cylinder 48. The two ninth cylinders 46 are respectively located on the left and right sides of the box opening position 12 and are fixedly arranged on the frame 1, the second seat 45 is fixedly arranged on the piston rod corresponding to the ninth cylinder 46, the tenth cylinder 48 is fixedly arranged on the second seat 45, the piston rod of the tenth cylinder 48 extends horizontally perpendicular to the X-axis direction, and the side push plate 47 is fixed on the piston rod of the tenth cylinder 48. The piston rod of the ninth cylinder 46 extends to preliminarily fold the side tongue 64, and then the piston rod of the tenth cylinder 48 extends to completely fold the side tongue 64.

[0055] Reference Figure 1 , Figure 2 and Figure 4 The folding mechanism of the snap tongue 63 includes a third seat 49, an eleventh cylinder 40, a twelfth cylinder 401 and a snap push plate 402. The eleventh cylinder 40 is fixedly arranged on the frame 1, and the eleventh cylinder 40 is located above the box opening position 12. The piston rod of the eleventh cylinder 40 is arranged vertically downward. The third seat 49 is fixedly arranged on the piston rod of the eleventh cylinder 40, and the twelfth cylinder 401 is fixedly arranged on the bottom surface of the third seat 49. The piston rod of the twelfth cylinder 401 faces the side of the box opening position 12, and the snap push plate 402 is fixed on the piston rod of the twelfth cylinder 401. After the base tongue 62 and the two side tongues 64 are folded, the piston rod of the eleventh cylinder 40 extends out, and the buckle push plate 402 abuts against the buckle tongue 63 to drive the buckle tongue 63 to perform preliminary folding. Then the piston rod of the twelfth cylinder 401 extends out, and the buckle push plate 402 pushes toward one side of the box body 61, which can drive the end of the buckle tongue 63 to insert into the gap formed by the base tongue 62 and the two side tongues 64, so that the buckle tongue 63 can be completely folded.

[0056] Reference Figure 4 A jet pipe is fixed on the second seat 45, one end of the jet pipe is connected to the jet device, and the other end of the jet pipe is arranged toward the paper box 6. After the folding mechanism 4 and the stabilizing component 5 are reset, the jet pipe sprays gas to push the paper box 6 away from the box position 12.

[0057] Reference Figure 5-Figure 7 The first driving member 51, the second driving member 31, the third driving member 33, the fourth driving member 53, and the fifth driving member 56 can all be pneumatic cylinders or electric cylinders.
