[0024] Embodiment

[0025] Please refer to Figures 1-4As shown in the figure, the utility model provides a short-side folding mechanism for cartons that is convenient for adjusting specifications, including a bottom plate 1 and a folding component. At the four corners of the top surface of the bottom plate 1, support rods 2 are fixedly arranged. At the top surface of the support rods 2, a top plate 3 is fixedly arranged. On the top surface of the bottom plate 1, a folding component is arranged. The folding component is composed of a first cylinder 4, a mold 6, an auxiliary cylinder 7, a side push plate 8, a mounting box 11, a vertical plate 13, a first cross plate 14, a second cross plate 15, a U-shaped plate 19, and a moving block 23. A first cylinder 4 is fixedly installed on the top surface of the top plate 3. The output end of the first cylinder 4 penetrates through the top plate 3 and is slidably connected to the top plate 3. At the bottom surface of the output end of the top plate 3, a U-shaped plate 19 is fixedly arranged. At the inner bottom of the U-shaped plate 19, a mounting box 11 is fixedly arranged. Symmetrical moving blocks 23 are slidably connected to the inner wall of the mounting box 11. At the bottom surface of the moving blocks 23, vertical plates 13 are fixedly arranged. On the sides of the vertical plates 13 close to each other, a first cross plate 14 and a second cross plate 15 are respectively fixedly arranged. On the top surface of the bottom plate 1, a mold 6 is fixedly arranged. Symmetrical auxiliary cylinders 7 are fixedly installed on the left and right sides of the mold 6. The output end of the auxiliary cylinder 7 penetrates into the mold 6 to the inside of the mold 6 and is slidably connected to the mold 6. At the end of the output end of the auxiliary cylinder 7, a side push plate 8 is fixedly arranged. The side push plate 8 is arranged inside the mold 6. Place the carton board between the first cross plate 14, the second cross plate 15, and the mold 6. Control the auxiliary cylinder 7 to drive the side push plate 8 to move to the position below the short side of the carton board at the same time. Control the first cylinder 4 to drive the U-shaped plate 19 to move downward, which can drive the mounting box 11 to move downward. The movement of the mounting box 11 drives the moving blocks 23 to move downward. The movement of the moving blocks 23 drives the vertical plates 13 to move downward, thereby driving the first cross plate 14 and the second cross plate 15 to move downward simultaneously and extend into the mold 6. The first cross plate 14 and the second cross plate 15 drive the carton board into the mold 6. The short sides on the left and right sides of the carton board contact the side push plate 8 and fold upward, thereby folding the short sides of the carton board. Control the auxiliary cylinder 7 to drive the side push plates 8 to approach each other and squeeze the short sides to achieve clamping and folding. After folding, control the auxiliary cylinder 7 to drive the side push plates 8 to move away from each other to the original position.

[0026] As Figures 1-4As shown in the figure, a limiting component is arranged above the bottom plate 1. The limiting component is composed of a lifting plate 9, lifting rods 10, a first clamping plate 16, a second clamping plate 17 and a second cylinder 20. The top surface of the installation box 11 is fixedly installed with the second cylinder 20. The top surface of the output end of the second cylinder 20 is fixedly provided with the lifting plate 9. Symmetric lifting rods 10 are arranged on the bottom surface of the lifting plate 9. A through groove adapted to the lifting rods 10 is arranged through the top surface of the vertical plate 13. The lifting rods 10 pass through the vertical plate 13 through the through groove and are slidably connected with the vertical plate 13. The bottom surfaces of the lifting rods 10 are respectively fixedly provided with the first clamping plate 16 and the second clamping plate 17. The cardboard box to be hemmed is placed on the top surfaces of the first clamping plate 16 and the second clamping plate 17. Controlling the second cylinder 20 to drive the lifting plate 9 to move upward can drive the lifting rods 10 to move upward. The movement of the lifting rods 10 drives the first clamping plate 16 and the second clamping plate 17 to move upward and approach the first cross plate 14 and the second cross plate 15 at the same time, so as to clamp and limit the cardboard box, avoiding the offset of the cardboard box before hemming. Convex strips 18 are fixedly connected to the top surfaces of the first clamping plate 16 and the second clamping plate 17. The material hardness of the convex strips 18 is stronger than that of the cardboard box. The convex strips 18 can set creases at the bottom of the left and right sides of the cardboard box during the process of the first clamping plate 16 and the second clamping plate 17 approaching the first cross plate 14 and the second cross plate 15, facilitating the hemming operation of the short side of the cardboard box.

[0027] As Figures 1-4As shown in the figure, an adjustment assembly is provided above the bottom plate 1. The adjustment assembly is composed of a servo motor 12, a bidirectional threaded rod 21, a fixed rod 22, a first insertion rod 24, a second insertion rod 25, and a T-shaped slider 26. A servo motor 12 is fixedly installed on the side of the installation box 11. The output end of the servo motor 12 penetrates through the installation box 11 to the inside of the installation box 11 and is rotatably connected to the installation box 11. The end of the output end of the servo motor 12 is fixedly provided with a bidirectional threaded rod 21. The other end of the bidirectional threaded rod 21 is rotatably connected to the installation box 11 through a bearing. The bidirectional threaded rod 21 penetrates through the moving block 23 and is threadedly connected to the moving block 23. A fixed rod 22 is fixedly provided between the left and right inner walls of the installation box 11. The fixed rod 22 penetrates through the moving block 23 and is slidably connected to the moving block 23. The first insertion rod 24 and the second insertion rod 25 are respectively fixedly provided on the sides of the second horizontal plate 15 and the second clamping plate 17. The first slots and the second slots adapted to the first insertion rod 24 and the second insertion rod 25 are respectively provided on the sides of the first horizontal plate 14 and the first clamping plate 16. The first insertion rod 24 and the second insertion rod 25 are respectively slidably connected to the first horizontal plate 14 and the first clamping plate 16 through the first slot and the second slot. The T-shaped slider 26 is fixedly provided on the top surface of the lifting rod 10. The T-shaped chute adapted to the T-shaped slider 26 is provided on the bottom surface of the lifting plate 9. The T-shaped slider 26 is slidably connected to the lifting plate 9 through the T-shaped chute. Controlling the servo motor 12 to drive the bidirectional threaded rod 21 to rotate can drive the moving blocks 23 to approach or move away from each other, so as to adjust the distance between the moving blocks 23. The movement of the moving blocks 23 drives the vertical plates 13 to approach or move away from each other. The movement of the vertical plates 13 drives the first horizontal plate 14 and the second horizontal plate 15 to approach or move away from each other. During the movement of the first horizontal plate 14 and the second horizontal plate 15, the first insertion rod 24 never disengages from the first slot. When the vertical plate 13 moves, it drives the lifting rod 10 and the first clamping plate 16 and the second clamping plate 17 to approach or move away from each other. During the movement of the first clamping plate 16 and the second clamping plate 17, the second insertion rod 25 never disengages from the second slot. Thus, it is convenient to adjust the distances between the first horizontal plate 14 and the second horizontal plate 15 and between the first clamping plate 16 and the second clamping plate 17 according to the specifications of the cardboard boxes, improving the applicability of the device. A controller 5 is fixedly installed on the top surface of the bottom plate 1. The controller 5 is electrically connected to the first cylinder 4, the auxiliary cylinder 7, the servo motor 12, and the second cylinder 20.

[0028] Specific working principle:

[0029] When the device is in use, place the cardboard box on the top surfaces of the first clamping plate 16 and the second clamping plate 17 below the first cross plate 14 and the second cross plate 15. Controlling the second cylinder 20 to drive the lifting plate 9 to move upward can drive the lifting rod 10 to move upward. The movement of the lifting rod 10 drives the first clamping plate 16 and the second clamping plate 17 to move upward simultaneously and approach the first cross plate 14 and the second cross plate 15, thereby clamping and limiting the cardboard box, avoiding the offset of the cardboard box before hemming. The convex strip 18 can set creases at the bottom of the left and right sides of the cardboard box during the process of the first clamping plate 16 and the second clamping plate 17 approaching the first cross plate 14 and the second cross plate 15, facilitating the hemming operation of the short side of the cardboard box. Controlling the auxiliary cylinder 7 to drive the side push plate 8 to move simultaneously to the position below the short side of the cardboard box, and controlling the first cylinder 4 to drive the U-shaped plate 19 to move downward can drive the mounting box 11 to move downward. The movement of the mounting box 11 drives the moving block 23 to move downward, and the movement of the moving block 23 drives the vertical plate 13 to move downward, thereby driving the first cross plate 14 and the second cross plate 15 to move downward simultaneously and extend into the mold 6. The first cross plate 14 and the second cross plate 15 drive the cardboard box into the mold 6. The short sides on the left and right sides of the cardboard box contact the side push plate 8 and fold upward, thereby hemming the short sides of the cardboard box. Controlling the auxiliary cylinder 7 to drive the side push plates 8 to approach each other and cooperate with the vertical plate 13 to squeeze the short sides can achieve clamping and folding. After folding, control the auxiliary cylinder 7 to drive the side push plates 8 to move away from each other to the original position, control the first cylinder 4 to drive the U-shaped plate 19 and the cardboard box to move upward to the original position, and then control the second cylinder 20 to drive the lifting plate 9 to move downward to the original position to release the limit on the cardboard box, facilitating the removal of the formed cardboard box and completing the hemming of the short side of the cardboard box.

[0030] When the device needs to hem cardboard boxes of different specifications, controlling the servo motor 12 to drive the bidirectional threaded rod 21 to rotate can drive the moving blocks 23 to approach or move away from each other, thereby adjusting the distance between the moving blocks 23. The movement of the moving blocks 23 drives the vertical plates 13 to approach or move away from each other. The movement of the vertical plates 13 drives the first cross plate 14 and the second cross plate 15 to approach or move away from each other. At the same time, the movement of the vertical plates 13 drives the lifting rods 10 and the first clamping plate 16 and the second clamping plate 17 to approach or move away from each other, thereby facilitating the adjustment of the distances between the first cross plate 14 and the second cross plate 15 and the first clamping plate 16 and the second clamping plate 17 according to the specifications of the cardboard box, improving the applicability of the device.
