Technical Field

[0001] This utility model relates to the field of cardboard processing technology, and in particular to a cardboard creasing device. Background Technology

[0002] Currently, corrugated cardboard is the main material for packaging boxes. Due to the inherent difficulty in bending corrugated cardboard, when bending the cut cardboard into boxes, it is necessary to first press creases into the cardboard using a creasing machine, and then workers bend the cardboard along the creases to fold the cardboard into boxes.

[0003] Currently, cardboard is often creasing by reciprocating rollers. While this method can create indentations, it can only creasing the left and right sides of the cardboard. It cannot continuously create horizontal and vertical indentations on the front and back. Usually, workers need to manually rotate the cardboard to create horizontal and vertical indentations on the front and back, which not only increases the workload of workers but also reduces the efficiency of creasing the four sides of the cardboard.

[0004] Therefore, it is necessary to provide a cardboard creasing device to solve the above-mentioned technical problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1-4 This utility model provides a cardboard creasing device, comprising a processing table 1, a rotating disk 2 rotatably connected to the top of the processing table 1, several limiting frames 3 fixedly connected to the top of the rotating disk 2, a support frame 4 and a support frame 5 on the top of the processing table 1, a drive motor 17 fixedly connected to both the support frame 4 and the support frame 5, a V-groove 6 penetrating through the support frame 4, two reciprocating lead screws 7 rotatably connected inside the V-groove 6, a moving block 8 on the outer surface of each of the two reciprocating lead screws 7, both moving blocks 8 slidably connected to the V-groove 6, a bevel gear 12 fixedly sleeved on the outer surface of each of the two reciprocating lead screws 7, the two bevel gears 12 meshing, a connecting frame 9 fixedly connected to the bottom of each of the two moving blocks 8, and two connecting frames 10 on the support frame 5. Each connecting frame 1 (9) and each of the two connecting frames 2 (10) has two rotatably connected rollers 11. The top of the processing table 1 is equipped with a support and guide assembly and a height adjustment assembly, and the bottom of the processing table 1 is equipped with a rotating assembly for driving the rotating disk 2 to rotate. Through the arrangement of the rotating disk 2, reciprocating screw 1 (7), connecting frame 1 (9), connecting frame 2 (10), rollers 11, reciprocating screw 2 (14), and moving block 2 (15), the cardboard is rotated and conveyed. During its rotation, it can be creasing twice on all four sides. This not only improves the quality of creasing and facilitates the subsequent folding of the cardboard into boxes, but also solves the problem that existing creasing devices can only creasing two sides of the cardboard, and the other two sides need to be manually rotated before creasing can be performed. This reduces the workload of workers and improves the efficiency of creasing the four sides of the cardboard.

[0020] The top of the support frame 2 5 has two guide grooves 13. The inside of each guide groove 13 is rotatably connected to a reciprocating screw 2 14. The output ends of the two drive motors 17 are fixedly connected to one end of one reciprocating screw 1 7 and one end of one reciprocating screw 2 14, respectively. The outer surface of each reciprocating screw 2 14 is provided with a moving block 2 15. The two connecting frames 2 10 are fixedly connected to the bottom of each moving block 2 15, and the two moving blocks 2 15 are slidably connected to the two guide grooves 13, respectively. One end of each reciprocating screw 2 14 rotatably passes through the support frame 2 5 and extends to the outside. The outer surface of each reciprocating screw 2 14 is fixedly fitted with a bevel gear 2 16, and the two bevel gears 2 16 mesh with each other. Through the arrangement of the support frame 2 5, the reciprocating screw 2 14 and the connecting frame 2 10, the corresponding rollers 11 can be moved down to crush the two sides of the cardboard, so that indentations are formed on the two sides, which facilitates the subsequent folding of the two sides into boxes.

[0021] The support and guide assembly includes four guide frames 18 fixedly connected to the top of the processing table 1. Support frame 1 4 and support frame 2 5 are slidably connected to the four guide frames 18 respectively. By setting the support and guide assembly, support frame 1 4 and support frame 2 5 can be supported and guided, improving their stability when moving up and down.

[0022] The height adjustment assembly includes two electro-hydraulic rods 19 fixedly installed on the top of the processing table 1. The telescopic ends of the two electro-hydraulic rods 19 are fixedly connected to the bottom of the support frame 1 4 and the support frame 2 5, respectively. By setting the height adjustment assembly, the roller 11 can be moved down to abut against and squeeze the cardboard, so as to create indentations on the cardboard.

[0023] The rotating assembly includes a stepper motor 20 fixedly installed at the bottom of the processing table 1. The output end of the stepper motor 20 is fixedly connected to the bottom of the rotating disk 2. By setting the rotating assembly, the rotating disk 2 and the cardboard placed inside the limiting frame 3 can be driven to rotate, so that they can perform creasing work.

[0024] Working principle: In use, place the cardboard to be crimped inside the front limiting frame 3, then start the stepper motor 20, causing its output end to drive the limiting frame 3 and the cardboard to rotate towards the controller. After the cardboard rotates to a position below one of the connecting frames 10 near the controller, the other limiting frame 3 rotates synchronously to the front of the device, allowing the cardboard to be crimped to be placed inside the limiting frame 3. Once the cardboard is below the connecting frame 10, activate the corresponding electric hydraulic rod 19 to retract its telescopic end. Under the guidance of the two guide frames 18, the support frame 4, reciprocating screw 14, bevel gear 16, and connecting frame 18 can be driven. The second frame 10 and the corresponding rollers 11 move down, so that the two rollers 11 abut against the top of the cardboard and move down to create a slight indentation. Then, the corresponding drive motor 17 is started, and its output end rotates, which drives one of the reciprocating screws 14 and bevel gears 16 to rotate. The bevel gears 16 drive the other bevel gears 16 that mesh with it to rotate, and cause the other reciprocating screws 14 to rotate synchronously. At this time, the moving block 15 moves along the axial direction of the reciprocating screws 14 under the guidance and limit of the guide groove 13, which drives the connecting frame 10 and the corresponding rollers 11 to move synchronously, which can perform preliminary crushing on the cardboard and create indentations on both sides. When the corresponding electric hydraulic rod 19 is engaged, the lowered roller 11 is reset. The cardboard that has been initially crushed rotates synchronously after the stepper motor 20 drives the rotating disk 2 to rotate again. This allows another cardboard to rotate synchronously with the cardboard under the support frame 2 5 and under the two connecting frames 2 10 respectively. This facilitates the initial crushing of both sides of the other cardboard. At the same time, the cardboard that has been initially crushed can have the crease position crushed a second time, increasing the depth of the crease and thus improving the quality of the crease, which is convenient for subsequent folding. After the two sides of the cardboard are creased, as the rotating disk 2 rotates, it can be rotated to the bottom of the support frame 2 5, and the rollers 11 on the connecting frame 2 10 will press the other two sides to create creases. A second pressing will be performed to improve the quality of the creases and to ensure that all four sides of the cardboard are pressed to create creases.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
