Detailed implementation mode
[0028] The present invention will be further described in detail below with reference to the accompanying drawings.
[0029] As Figures 1 to 2 shown, the structure and function of the packaging carton will be described in detail below;
[0030] A packaging carton, a folding inner layer 2 is arranged inside the packaging carton 1, and the folding inner layer 2 is in a wave-bent shape;
[0031] As Figure 1 shown, the folding inner layer 2 can be unfolded or folded. Figure 1 Figure shows the unfolded state of the folding inner layer 2. After the folding inner layer 2 is unfolded, it forms a plurality of bent W shapes. Then, some items can be stored in each folding space of the folding inner layer 2, thereby completing the separation of the items. And the folding inner layer 2 can be folded, so that the folding inner layer 2 is on the side of the packaging carton 1. Then, through the folding structure of the folding inner layer 2, the items in the packaging carton 1 can be shock-absorbed;
[0032] As Figure 2 shown, two folding inner layers 2 are provided, and the two folding inner layers 2 are respectively arranged on the front and back or left and right sides inside the packaging carton 1;
[0033] In this way, after the folding inner layer 2 is folded, folding inner layers 2 are formed on both sides inside the packaging carton 1. The folding structure of the folding inner layer 2 can shock-absorb the items in the packaging carton 1, thereby realizing shock absorption on both sides of the items in the packaging carton 1;
[0034] Since the folding inner layer 2 is the core distinguishing technical feature of this patent compared with the packaging carton 1 in the prior art, a device for processing the folding inner layer 2 is designed;
[0035] As Figures 3 to 8 shown, the structure and function of the packaging carton processing device will be described in detail below;
[0036] A packaging carton processing device includes a device support 3, a support mold 4 fixedly connected to the device support 3, a clamping mechanism 5 fixedly connected to the device support 3, moving brackets 6 fixedly connected to both sides of the device support 3, indentation mechanisms 9 slidably connected to the two moving brackets 6, a folding mechanism 8 fixedly connected to the device support 3, and a cardboard 10 clamped by the folding mechanism 8;
[0037] During use, as Figure 4 shown, place the cardboard 10 on the support mold 4, clamp and fix the cardboard 10 through the clamping mechanism 5, and the folding mechanism 8 clamps the cardboard 10 to form a state as Figure 4 shown. At this time, the folding mechanism 8 swings to the left. Under the limitation of the clamping mechanism 5, the cardboard 10 is bent. At this time, the folding mechanism 8 moves to the left, starts the indentation mechanism 9 on the right, so that the indentation mechanism 9 presses on the cardboard 10, and then the folding mechanism 8 moves to the right. Under the limitation of the indentation mechanism 9 on the right, the cardboard 10 is bent, then the indentation mechanism 9 on the left presses on the cardboard 10, and then the folding mechanism 8 moves to the left. Under the limitation of the indentation mechanism 9 on the left, the cardboard 10 is bent, the indentation mechanism 9 on the right is withdrawn, and then presses on the cardboard 10 again, and then the folding mechanism 8 moves to the right. Under the limitation of the indentation mechanism 9 on the right, the cardboard 10 is bent, the indentation mechanism 9 on the left is withdrawn, and then presses on the cardboard 10 again. Repeat the movement multiple times in sequence to complete multiple bends of the cardboard 10 and form the folding inner layer 2;
[0038] As Figure 6 shown, the structure and function of the clamping mechanism 5 will be described in detail below;
[0039] The clamping mechanism 5 includes a telescopic mechanism I 51 and a clamping plate 52 fixedly connected to the telescopic end of the telescopic mechanism I 51, and the telescopic mechanism I 51 is fixedly connected to the device support 3;
[0040] During use, place the cardboard 10 to be bent on the support mold 4, start the telescopic mechanism I 51. The telescopic mechanism I 51 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 51 drives the clamping plate 52 to move, so that the clamping plate 52 moves downward to clamp the cardboard 10;
[0041] Furthermore, as Figure 7 shown, the structure and function of the indentation mechanism 9 will be described in detail below;
[0042] A lead screw 7 is rotatably connected to the movable support 6, and a power mechanism I for driving the lead screw 7 to rotate is fixedly connected to the movable support 6; the power mechanism I is preferably a servo motor; the indentation mechanism 9 includes a movable seat 91, the movable seat 91 is slidably connected to the movable support 6, and the movable seat 91 is threadedly connected to the lead screw 7;
[0043] When it is necessary to drive the indentation mechanism 9 to move horizontally, start the power mechanism I. The output shaft of the power mechanism I starts to rotate. The output shaft of the power mechanism I drives the lead screw 7 to rotate. When the lead screw 7 rotates, it drives the indentation mechanism 9 to move through the thread, thereby adjusting the position of the indentation mechanism 9 and enabling the indentation mechanism 9 to move horizontally;
[0044] A conversion motor 92 is fixedly connected to the movable seat 91. A telescopic mechanism IV 93 is fixedly connected to the output shaft of the conversion motor 92. An indentation plate 94 is fixedly connected to the telescopic end of the telescopic mechanism IV 93;
[0045] The conversion motor 92 can be started. The conversion motor 92 is preferably a servo motor. The output shaft of the conversion motor 92 drives the telescopic mechanism IV 93 to rotate. The telescopic mechanism IV 93 drives the indentation plate 94 to rotate, so that the indentation plate 94 rotates to a position where it can indent the cardboard 10, as Figure 8 shown. Here, the indentation plate 94 rotates 180°. This design is because in the initial state, the cardboard 10 is too long. In order to ensure that the cardboard 10 will not be blocked by the indentation plate 94 when it is flipped, the indentation plate 94 is first rotated to the other side to clear the movement position of the cardboard 10. Then start the telescopic mechanism IV 93. The telescopic mechanism IV 93 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism IV 93 drives the indentation plate 94 to move, adjusting the height of the indentation plate 94, so that the indentation plate 94 can squeeze and limit the cardboard 10;
[0046] Next, the structure and function of the folding mechanism 8 will be described in detail;
[0047] The folding mechanism 8 includes a telescopic mechanism II 81. The telescopic mechanism II 81 is fixedly connected to the device support 3. A swing motor 82 is fixedly connected to the telescopic end of the telescopic mechanism II 81. A telescopic mechanism III 83 is fixedly connected to the output shaft of the swing motor 82. A sliding support 84 is fixedly connected to the telescopic end of the telescopic mechanism III 83. Two sliding seats 85 are slidably connected to the sliding support 84. A compression spring is fixedly connected between the sliding seat 85 and the sliding support 84. A clamping roller 86 is rotatably connected to the sliding seat 85; a power mechanism II for driving the clamping roller 86 to rotate is fixedly connected to the sliding seat 85;
[0048] During use, place the cardboard 10 between two clamping rollers 86. The two clamping rollers 86 can clamp cardboard 10 with different thicknesses. Use the driving force generated by the compression spring between the sliding seat 85 and the sliding bracket 84 to move the two clamping rollers 86, so that the two clamping rollers 86 tend to approach each other, causing the two clamping rollers 86 to approach each other to clamp the cardboard 10, forming a state as shown in Figure 5 At this time, pre-start the telescopic mechanism I 51. The telescopic end of the telescopic mechanism I 51 drives the clamping plate 52 to move, so that the clamping plate 52 clamps the cardboard 10.
[0049] Furthermore, before the clamping plate 52 clamps the cardboard 10, start the power mechanism II. The output shaft of the power mechanism II starts to rotate. The output shaft of the power mechanism II drives the clamping roller 86 to rotate. The rotation of the clamping roller 86 drives the cardboard 10 to move, so that the cardboard 10 moves horizontally, thereby adjusting the position of the cardboard 10 on the support mold 4, and further adjusting the length of the bottom of the folded cardboard 10.
[0050] Furthermore, start the swing motor 82. The output shaft of the swing motor 82 starts to rotate. The output shaft of the swing motor 82 drives the telescopic mechanism III 83 to rotate. The telescopic mechanism III 83 drives the sliding bracket 84 to rotate, so that the sliding bracket 84 swings from one side to the other side, thereby driving the cardboard 10 to move, and thus the unfolded part of the cardboard 10 is folded from one side to the other side.
[0051] After the clamping plate 52 clamps the cardboard 10 to form the first fold, start the power mechanism I. The output shaft of the power mechanism I drives the lead screw 7 to rotate, so that the indentation plate 94 approaches the cardboard 10. Start the telescopic mechanism IV 93. The telescopic end of the telescopic mechanism IV 93 drives the indentation plate 94 to move, so that the indentation plate 94 squeezes and positions the cardboard 10.
[0052] Start the swing motor 82. The output shaft of the swing motor 82 starts to rotate. The output shaft of the swing motor 82 drives the telescopic mechanism III 83 to rotate. The telescopic mechanism III 83 drives the sliding bracket 84 to rotate, so that the sliding bracket 84 swings from one side to the other side, thereby driving the cardboard 10 to move, and thus the unfolded part of the cardboard 10 is folded from one side to the other side, completing the folding of the cardboard 10 under the limitation of the indentation plate 94.
[0053] Further, in order to control the shape accuracy of the cardboard 10 after folding and ensure that the unbent part of the cardboard 10 is in a horizontal state every time the cardboard 10 is bent. That is, during the multiple bending processes of the cardboard 10, the thickness of the cardboard 10 on the support die 4 will continuously increase. Then, the telescopic mechanism II 81 is activated. The telescopic mechanism II 81 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 81 drives the cardboard 10 to move, and then adjusts the height of the un-folded part of the cardboard 10 when the cardboard 10 is in a horizontal state, ensuring that the un-folded part of the cardboard 10 is in a horizontal state.
[0054] Further, the telescopic mechanism III 83 is activated. The telescopic mechanism III 83 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism III 83 drives the clamping roller 86 to move, and then adjusts the clamping position of the clamping roller 86 on the cardboard 10.
[0055] Further, by adjusting the lateral position of the indentation plate 94, the indentation position of the indentation plate 94 on the cardboard 10 is adjusted, and then the bending size of the cardboard 10 is adjusted.
[0056] A method for processing a packaging carton, the method comprising the following steps:
[0057] Step 1: Place the cardboard 10 on the support die 4 and clamp and fix the cardboard 10 through the clamping mechanism 5. Place the cardboard 10 to be bent on the support die 4, activate the telescopic mechanism I 51. The telescopic mechanism I 51 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 51 drives the clamping plate 52 to move, so that the clamping plate 52 moves downward, and the clamping plate 52 clamps the cardboard 10.
[0058] Step 2: The folding mechanism 8 clamps the end of the cardboard 10, and the folding mechanism 8 drives the cardboard 10 to swing left and right. The output shaft of the swing motor 82 starts to rotate. The output shaft of the swing motor 82 drives the telescopic mechanism III 83 to rotate. The telescopic mechanism III 83 drives the sliding bracket 84 to rotate, so that the sliding bracket 84 swings from one side to the other side, and then drives the cardboard 10 to move. Then, the un-folded part of the cardboard 10 is folded from one side to the other side.
[0059] Step 3: While the cardboard 10 is swinging, insert the indentation mechanism 9 to the upper side of the cardboard 10 to complete the folding of the cardboard 10; the folding mechanism 8 swings. Under the limitation of the clamping mechanism 5, the cardboard 10 is bent. At this time, the folding mechanism 8 moves to the left, and the indentation mechanism 9 on the right is activated, so that the indentation mechanism 9 presses on the cardboard 10. Then the folding mechanism 8 moves to the right. Under the limitation of the indentation mechanism 9 on the right, the cardboard 10 is bent. Then the indentation mechanism 9 on the left presses on the cardboard 10. Then the folding mechanism 8 moves to the left. Under the limitation of the indentation mechanism 9 on the left, the cardboard 10 is bent. The indentation mechanism 9 on the right is withdrawn and then presses on the cardboard 10 again. Then the folding mechanism 8 moves to the right. Under the limitation of the indentation mechanism 9 on the right, the cardboard 10 is bent. The indentation mechanism 9 on the left is withdrawn and then presses on the cardboard 10 again. Repeat the movement multiple times in sequence to complete multiple bends of the cardboard 10 and form the folding inner layer 2.
