[0027] like Figure 1 As shown, it shows an automatic carton packaging machine in one embodiment of the present invention, comprising: Feeding table 1, the front end of the top wall of the feeding table 1 is provided with bosses on both sides, the two bosses are installed with the feeding assembly 2, the feeding assembly 3 is installed in the feeding table 1, and the glue coating machine body 4 is fixed in the middle of the top wall of the feeding table 1; Conveyor belt 5, which is arranged parallel to the feeding platform 1, and a guide assembly 6 is installed above the frame of the conveyor belt 5; The pushing platform 7 is installed at the end of the conveyor belt 5. The rear side of the top wall of the pushing platform 7 is equipped with a pushing assembly 8, and the middle part of the top wall of the pushing platform 7 is fixed with a guide bar 9; The material clamping assembly 11 is fixed to the rear side of the feeding platform 1 through the L-shaped frame 10; The laminating component 12 is installed at the end of the feeding platform 1.

[0028] In this embodiment, the provided unloading component 2 can cooperate with the feeding component 3 to push the stacked shells a individually to the next processing step, the provided glue coating machine body 4 is used to perform glue coating operations on the shells a, the provided conveyor belt 5 cooperates with the guide component 6 to transfer the inner shell b to the pushing platform 7, and cooperates with the provided pushing component 8 to push the inner shell b to the position of the clamping component 11, the provided clamping component 11 is used to move the inner shell b to the bottom wall of the shell a, and bond the inner shell b to the shell a, and the provided fitting component 12 flips one side of the shell a and bonds it to the side wall of the inner shell b.

[0029] like Figures 2 to 4 As shown, it shows the blanking component 2 and the feeding component 3 in one embodiment of the present invention. The blanking component 2 includes two groups of push knives 21. Each group of push knives 21 is slidably mounted on the top wall of the corresponding boss. Each group of adjacent push knives 21 is fixedly connected by a connecting shaft 22. A No. 1 cylinder 23 is fixed to the top wall of the feeding platform 1. The movable end of the No. 1 cylinder 23 is fixedly connected to the side wall of the corresponding group of push knives 21. Two L-shaped plates 24 are symmetrically fixed to the front end of the boss. A through groove 13 is provided at the bottom of the side wall of the L-shaped plate 24. The feeding assembly 3 includes a lead screw 31 and a guide shaft 32 arranged in parallel. The lead screw 31 is rotatably installed between the inner walls of the feeding platform 1, and the guide shaft 32 is fixed between the inner walls of the feeding platform 1. A slider 33 is screwed on the lead screw 31, and the guide shaft 32 slides through the slider 33. A driving motor 34 is fixed to the front wall of the feeding platform 1. The power shaft of the driving motor 34 slides through the front wall of the feeding platform 1 and is fixedly connected to the front end of the lead screw 31. A connecting plate 35 is fixedly installed on the top wall of the slider 33, and a push block 36 is fixed to the top of the connecting plate 35.

[0030] A limiting groove 14 is formed through the top wall of the feeding platform 1 , and the push block 36 is slidably installed in the limiting groove 14 , and the top wall of the push block 36 is lower than the top wall of the boss.

[0031] The driving motor 34 is a stepping motor or a servo motor.

[0032] In this embodiment, the blanking assembly 2 cooperates with the feeding assembly 3 to push the stacked shells a individually to the next processing step. Initially, multiple shells a are stacked together with one end inserted between two L-shaped plates 24. Shells a are placed horizontally between the two bosses, with the push blades 21 on either side contacting the ends of the shells a. When unloading is required, the No. 1 cylinder 23 on one side is extended, and the No. 1 cylinder 23 on the other side is shortened synchronously. At this time, the extended No. 1 cylinder 23 pushes one side of the shell a away from the corresponding boss, and the shell a located at the bottom side is tilted and set between the boss and the top wall of the feeding platform 1. Then the drive motor 34 is controlled to work, and the drive motor 34 drives the screw 31 to rotate, and the screw 31 drives the slider 33 to move backward. The slider 33 drives the push block 36 to move through the connecting plate 35. The push block 36 pushes the tilted shell a toward the position of the gluing machine body 4. When the shell a completely falls to the feeding platform 1, it is pushed to the position of the gluing machine body 4 by the push block 36 for the gluing operation (in order to ensure that the shell a does not deflect during the movement, two limit rods can also be set at the rear of the feeding platform 1 so that the shell a can move straight toward the rear side of the feeding platform 1). At the same time, the push block 36 is relatively long, so that when the slider 33 moves to the rear end of the feeding platform 1, it can push the shell a into the bonding component 12.

[0033] like Figure 5~Figure 6 As shown, it shows the guide assembly 6 and the pusher assembly 8 in one embodiment of the present invention. The guide assembly 6 includes two symmetrically arranged vertical plates 61. A cross bar 62 is fixed between the top ends of each set of vertical plates 61. Two sliding sleeves 63 are slidably installed on the cross bar 62. The top ends of the sliding sleeves 63 are screwed with threaded knobs 64, and the bottom ends of the sliding sleeves 63 are fixed with vertical rods 65. A guide rod 66 is fixed between the bottom ends of the two corresponding vertical rods 65.

[0034] The pushing assembly 8 includes a mounting block 81, which is fixed on the top wall of the pushing platform 7. The front wall of the mounting block 81 is fixed with an electric guide rail No. 1 82, the front wall of the electric slider on the electric guide rail No. 1 82 is fixed with a connecting rod 83, and the other end of the connecting rod 83 is fixed with a push plate 84.

[0035] In this embodiment, the guide assembly 6 is provided to move the inner shell b onto the pusher 7 while maintaining the same direction. The inner shell b is arranged parallel to the pusher 7. During the rotation of the conveyor belt 5, the inner shell b can be transferred from the two guide rods 66 to the pusher 7. At the same time, the threaded knob 64 provided on the sliding sleeve 63 can adjust the position of the sliding sleeve 63, and thus adjust the position of the guide rods 66 on both sides to meet different usage requirements. After the inner shell b moves onto the pusher 7, the first electric guide rail 82 drives the push plate 84 on the connecting rod 83 to move, thereby pushing the inner shell b to the bottom of the clamping assembly 11, so that the clamping assembly 11 can smoothly clamp the inner shell b to the outer shell a for bonding.

[0036] like Figure 7 As shown, it shows a clamping assembly 11 in an embodiment of the present invention, the clamping assembly 11 includes a No. 2 electric guide rail 111, the No. 2 electric guide rail 111 is fixed on the bottom wall of the beam of the L-shaped frame 10, the bottom wall of the electric slider on the No. 2 electric guide rail 111 is fixed with a No. 2 cylinder 112, the movable end at the bottom of the No. 2 cylinder 112 is fixed with a cross plate 113, the bottom wall of the cross plate 113 is fixed with an electric clamp 114, the center of the bottom wall of the cross plate 113 is fixed with a No. 3 cylinder 115, and the movable end at the bottom of the No. 3 cylinder 115 is fixed with a pressure plate 116.

[0037] In this embodiment, the clamping assembly 11 is used to clamp the inner shell b onto the outer shell a coated with glue for bonding. When the clamping component 11 is working, the electric clamp 114 at its bottom is driven to move above the inner shell b by the No. 2 electric guide rail 111. At the same time, the outer shell a is moved to the bottom of the L-shaped frame 10 under the action of the feeding component 3. When the electric clamp 114 moves to above the inner shell b, the No. 2 cylinder 112 is controlled to extend. The No. 2 cylinder 112 moves the electric clamp 114 to the outside of the inner shell b, controls the electric clamp 114 to work, clamps the inner shell b, and then controls the No. 2 cylinder 112 to contract. The No. 2 electric guide rail 111 drives the inner shell b on the electric clamp 114 to move to the position where the glue is applied to the outer shell a, and then controls the No. 2 cylinder 112 to extend until the inner shell b fits on the top wall of the outer shell a, controls the No. 3 cylinder 115 to extend, and the No. 3 cylinder 115 drives the pressure plate 116 to move downward, further squeezing the inner shell b onto the outer shell a to ensure that the inner shell b and the outer shell a are stably bonded.

[0038] like Figure 8 As shown, it shows a fitting component 12 in an embodiment of the present invention, the fitting component 12 includes a mounting platform 121, the top wall of the inner cavity of the mounting platform 121 is fixed with a No. 4 cylinder 122, the movable end at the bottom of the No. 4 cylinder 122 is fixed with a pressure block 123, the bottom wall of the inner cavity of the mounting platform 121 is provided with a groove 124, the bottom wall of the groove 124 is fixed with a No. 5 cylinder 125, the movable end of the top of the No. 5 cylinder 125 is fixed with a support block 126, the side wall of the groove 124 is provided with a mounting groove 127, the inner wall of the mounting groove 127 is fixed with a No. 6 cylinder 128, the movable end of the No. 6 cylinder 128 is fixed with a side plate 129, and the side plate 129 is slidably installed in the mounting groove 127.

[0039] A rotating roller 15 is rotatably mounted on one side of the top wall of the groove 124 .

[0040] In this embodiment, the purpose of providing the laminating assembly 12 is to flip one side of the outer shell a and affix it to the side wall of the inner shell b. After the initial bonding, the inner shell b and the outer shell a are pushed onto the support block 126 by the feeding assembly 3. The fourth cylinder 122 is controlled to extend, and the fourth cylinder 122 drives the pressure block 123 downward to press the inner shell b against the top wall of the outer shell a. Then, the fourth cylinder 122 is controlled to extend and the fifth cylinder 125 is controlled to contract. The inner shell b and the outer shell a are clamped between the support block 126 and the pressure block 123 and moved downward into the groove 124. At this time, one side of the outer shell a is folded vertically. The sixth cylinder 128 is controlled to extend, and the sixth cylinder 128 drives the side plate 129 to affix the flipped side of the outer shell a to the side wall of the inner shell b, so that the outer shell a and the inner shell b are bonded. After bonding, the fourth cylinder 122 and the sixth cylinder 128 are controlled to return to their original positions. The bonded cardboard box is removed, completing the packaging operation.
