[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0025] Combination Figure 1 A creasing device for corrugated cardboard box production includes a base plate 1, a side plate 11 fixedly connected to one side of the base plate 1, and a top plate 111 fixedly connected to the top of the side plate 11. A placement component 3 is provided at the top of the base plate 1, and a creasing component 5 is provided at the bottom of the top plate 111.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Please see Figures 1-5 The placement component 3 includes a support plate 31 fixedly connected to the top of the base plate 1, a first motor 32 fixedly connected to one side of the support plate 31, a threaded rod 33 fixedly connected to the output end of the first motor 32, a first connecting plate 34 and a second connecting plate 35 threadedly connected to the outer surface of the threaded rod 33, a placement plate 36 fixedly connected to the top of the second connecting plate 35, and a scale plate 37 provided on one side of the placement plate 36. The top of the placement plate 36 is provided with an indentation line 363, and the top of the placement plate 36 is respectively provided with a first groove 361 and a second groove 362. The top of the first connecting plate 34 is provided with a fixing component 2. One end of the threaded rod 33 is rotatably connected to the side wall of the side plate 11, and the other end of the threaded rod 33 rotatably passes through the support plate 31. The first motor 32 drives the threaded rod 33 to rotate, which in turn moves the first connecting plate 34 and the second connecting plate 35, thereby moving the placement plate 36. The placement plate 36 is moved below the creasing assembly 5, making it easier to creasing the cardboard at the top of the placement plate 36. The scale plate 37 and the creasing line 363 allow operators to quickly and accurately mark and align the cardboard, ensuring that the position of the creasing line 363 is the same as the pre-marked creasing position on the cardboard, thus ensuring the consistency of the creasing position each time. The scale plate 37 records the specific distance of the cardboard creasing, making the whole process more intuitive and clear.

[0028] The fixing assembly 2 includes a power box 21 fixedly connected to the top of the first connecting plate 34, a second motor disposed inside the power box 21, a rotating shaft fixedly connected to the output end of the second motor, a gear 22 fixedly connected to one end of the rotating shaft, racks 23 meshing with both sides of the gear 22, fixing plates 26 fixedly connected to one side of the two sets of racks 23, fixing blocks 27 fixedly connected to the top of the two sets of fixing plates 26, and first baffles 28 fixedly connected to the top of the two sets of fixing blocks 27. The rotating shaft rotates through the power box 21, and both sets of fixing blocks 27 are slidably connected to the first slide groove 361. The second motor drives the rotating shaft and gear 22 to rotate. The rotation of the gear 22 drives the two sets of racks 23 to move in the same or opposite directions. The movement of the two sets of racks 23 in the same or opposite directions drives the two sets of first baffles 28 to move in the same or opposite directions, which facilitates fixing both sides of the cardboard to effectively clamp the cardboard and ensure that the cardboard does not shift during the creasing process.

[0029] A connecting frame 24 is fixedly connected to the top of the power box 21. Third sliding grooves 25 are respectively formed on the inner walls of both sides of the connecting frame 24. First sliders are slidably connected inside each of the two sets of third sliding grooves 25, and each set of first sliders is fixedly connected to one of the two sets of racks 23. When the gear 22 rotates, driving the two sets of racks 23 to move in the same or opposite directions, the two sets of first sliders slide along the two sets of third sliding grooves 25, providing a guiding function to ensure smoother and more precise linear movement of the two sets of racks 23.

[0030] Each fixed block 27 has a connecting rod 271 fixedly connected to one side. One end of each of the two sets of connecting rods 271 is fixedly connected to a connecting block 8. The top of each of the two sets of connecting blocks 8 is fixedly connected to a second baffle 81. The two sets of connecting blocks 8 are slidably connected to the second slide groove 362. The two sets of second baffles 81 and the two sets of first baffles 28 are symmetrically arranged about the indentation line 363. When the two sets of first baffles 28 move in the same or opposite direction, they drive the two sets of second baffles 81 to move in the same or opposite direction, thus facilitating further fixation of the cardboard side.

[0031] The creasing assembly 5 includes an electric push rod 51 fixedly connected to the bottom end of the top plate 111, a mounting base 52 fixedly connected to the telescopic end of the electric push rod 51, a mounting groove 521 formed at the bottom end of the mounting base 52, a creasing plate 53 movably connected inside the mounting groove 521, and a locking bolt 54 threaded between the creasing plate 53 and the mounting base 52. The telescopic movement of the electric push rod 51 causes the mounting base 52 to move up and down, thereby moving the creasing plate 53 to facilitate creasing of the cardboard. The creasing plate 53 is fixed to the mounting base 52 by the locking bolt 54. Removing the locking bolt 54 facilitates maintenance or replacement of the creasing plate 53.

[0032] An infrared sensor 4 is installed at the bottom of the top plate 111, and an infrared emitter 6 is installed on one side of the placement plate 36. The infrared sensor 4 is connected to the electric push rod 51 and the first motor 32. As the placement plate 36 moves, when the crease line 363 is directly below the crease plate 53, the infrared sensor 4 receives the signal from the infrared emitter 6. At this time, the first motor 32 stops rotating, and the electric push rod 51 begins to extend and retract, facilitating the crease treatment of the cardboard.

[0033] A control panel 7 is provided on one side of the side panel 11. The infrared sensor 4, infrared transmitter 6, electric push rod 51, first motor 32, and second motor are all connected to the control panel 7 via signal. The control panel 7 facilitates centralized control of the working status of the infrared sensor 4, infrared transmitter 6, electric push rod 51, first motor 32, and second motor.

[0034] A fourth sliding groove 12 is provided at the top of the base plate 1. A second slider 341 is fixedly connected to the bottom of the first connecting plate 34, and a third slider 351 is fixedly connected to the bottom of the second connecting plate 35. Both the second slider 341 and the third slider 351 are slidably connected to the fourth sliding groove 12. When the threaded rod 33 rotates, it drives the first connecting plate 34 and the second connecting plate 35 to move. The second slider 341 and the third slider 351 slide along the fourth sliding groove 12, which plays a guiding role to ensure that the first connecting plate 34 and the second connecting plate 35 always maintain linear motion during the movement.

[0035] In use, place the cardboard to be creasing on the top of the placement plate 36. Mark and align the position of the cardboard using the scale plate 37 and the creasing line 363. The second motor drives the rotating shaft and gear 22 to rotate. The rotation of gear 22 causes two sets of racks 23 to move in the same or opposite directions, thereby causing two sets of first baffles 28 to move in the same or opposite directions to facilitate fixing the sides of the cardboard. The movement of the two sets of first baffles 28 in the same or opposite directions causes the two sets of second baffles 81 to move in the same or opposite directions to facilitate further fixing the sides of the cardboard. After fixing is completed, start the first motor. Motor 32 drives the threaded rod 33 to rotate, causing the first connecting plate 34 and the second connecting plate 35 to move along the threaded rod 33, thereby moving the placement plate 36 to below the creasing assembly 5. When the creasing line 363 is directly below the creasing plate 53, the infrared sensor 4 receives the signal from the infrared transmitter 6. At this time, the first motor 32 stops rotating, and the electric push rod 51 begins to extend and retract, which facilitates the creasing process on the cardboard. After the creasing is completed, the first motor 32 is started in reverse, causing the placement plate 36 to move out of the creasing assembly, preparing for the next creasing process.
