Description

Technical Field

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

[0002] Cardboard boxes are a type of packaging material made of cardboard, commonly used for storing and transporting various goods. Their main characteristics are lightness, sturdiness, ease of production, and recyclability. Cardboard boxes are usually composed of multiple layers of cardboard, including corrugated cardboard and hard cardboard, which can effectively protect the contents from damage. In order to optimize the folding and assembly process of cardboard boxes, creasing is performed during the cardboard box production process. Creases create certain weaknesses at the key folding positions of the cardboard box, making it easier for the cardboard box to fold along the crease line when folding. Crease devices are generally used, but most existing cardboard box creasing devices still have problems that need to be solved.

[0003] Most existing cardboard creasing devices are not convenient for replacing creasing wheels. Different sizes of cardboard boxes generally require creasing wheels of corresponding sizes to ensure creasing quality. If the creasing wheels are difficult to disassemble and assemble, it will take a long time. Frequent replacement will cause production line downtime, thus affecting production efficiency. It also requires more manpower to complete this process, increasing labor input and operating costs. Therefore, it is necessary to design a creasing device for cardboard box production and processing to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a creasing device for carton production and processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A creasing device for cardboard box production includes an operating table. A U-shaped frame is mounted on the top of the operating table. Two fixing blocks are fixedly connected to the inner walls of the top of each end of the U-shaped frame. Two first guide rods are fixedly connected to the two fixing blocks at the same end, with the first guide rods at the same end fitted with the same first movable block. An L-shaped frame is fixedly connected to the bottom of each of the two first movable blocks. A square groove is formed at the adjacent end of each of the two L-shaped frames. A second guide rod is disposed within the square groove and fixedly connected to the L-shaped frame. A second movable block is disposed within the square groove and fitted onto the second guide rod, with the second movable block slidably connected to the second guide rod. The system comprises a rod and an L-shaped frame. A spring is mounted on one side of the second movable block, and the spring is sleeved on the second guide rod. A baffle is fixedly connected to the bottom of the second movable block. A mounting plate is mounted on one side of the baffle, and the mounting plate has two positioning slots. Positioning pins are installed in the positioning slots, and the two positioning pins at the same end are fixedly connected to the same connecting plate. The connecting plate is fixedly connected to the top inner wall of the L-shaped frame. A square plate is mounted on one side of the baffle, and L-shaped plates are fixedly connected to the same side of both square plates. Both L-shaped plates are fixedly connected to the operating platform. U-shaped seats are fixedly connected to the bottom of both mounting plates, and bearings are installed at both ends of the U-shaped seats. The outer ring of the bearing is fixedly connected to the outer wall of the U-shaped seat. The inner walls of the inner rings of the two bearings are fixedly connected to the same indentation wheel. A fixing rod passes through the indentation wheel, and a hole adapted to the fixing rod is opened on the indentation wheel. The fixing rod is fixedly connected to an L-shaped frame. Due to the use of a baffle, positioning pin, mounting plate, connecting plate, and fixing rod to restrict the position of the indentation wheel, the position of the mounting plate can be ensured when the baffle is on one side of the mounting plate. When the moving frame is moved so that the baffle contacts the square plate, continuing to move the moving frame can move the baffle away from one side of the mounting plate, thereby releasing the restriction on the mounting plate. The mounting plate can then be removed from the positioning pin, the indentation wheel can be replaced, and after the mounting plate is placed on the positioning pin, the moving frame can be moved away from the L-shaped plate to retract. The compressed spring will extend, allowing the baffle to move to one side of the mounting plate, thus restricting the position of the mounting plate. This effectively solves the problem that most existing carton creasing devices, as mentioned in the background technology, are inconvenient for replacing creasing wheels. Different sizes of cartons generally require creasing wheels of corresponding specifications to ensure creasing quality. If the creasing wheels are difficult to disassemble and assemble, it will take a long time. Frequent replacements will cause production line downtime, thus affecting production efficiency and requiring more manpower to complete this process, increasing labor input and operating costs. This technology effectively reduces the difficulty of disassembling and assembling creasing wheels, enables quick replacement of creasing wheels, greatly improves the efficiency of creasing wheel replacement, and reduces downtime.

[0006] As a further embodiment of this utility model, a movable frame is provided on the top of the U-shaped frame, and a first electric push rod is fixedly connected to the top of the movable frame, with the output end of the first electric push rod fixedly connected to the U-shaped frame.

[0007] As a further embodiment of this utility model, a third guide rod is fixedly connected to the top of both ends of the U-shaped frame. The third guide rod passes through the movable frame and is slidably connected to the movable frame.

[0008] As a further embodiment of this utility model, slots are provided on both sides of the movable frame, and a second electric push rod is provided in each slot on both sides of the movable frame. The second electric push rod is fixedly connected to the U-shaped frame, and the output end of the second electric push rod passes through the U-shaped frame and is fixedly connected to the L-shaped frame. Two fourth guide rods are fixedly connected to the L-shaped frame on the side near the second electric push rod. The fourth guide rods pass through the U-shaped frame and are slidably connected to the U-shaped frame.

[0009] As a further embodiment of this utility model, an installation slot is provided on the operating table, and a U-shaped mounting bracket is provided in the installation slot. The U-shaped mounting bracket is fixedly connected to the operating table, and a servo motor is fixedly connected to one side of the U-shaped mounting bracket. A drive screw is fixedly connected to the output end of the servo motor, and a screw nut is sleeved on the drive screw. The screw nut is adapted to the drive screw, and a movable seat is fixedly connected to the outer wall of the screw nut. Movable frames are fixedly connected to both sides of the movable seat, and a fifth guide rod is passed through both ends of the movable seat. The fifth guide rod is fixedly connected to the U-shaped mounting bracket, and the movable seat is slidably connected to the fifth guide rod.

[0010] As a further embodiment of this utility model, a third moving block is fixedly connected to the inner wall of the bottom of both ends of the movable frame, and a sixth guide rod is passed through each of the two third moving blocks. The third moving blocks are slidably connected to the sixth guide rods, and the two sixth guide rods are fixedly connected to the operating table.

[0011] As a further embodiment of this utility model, the top of the operating table is provided with two indentation strips, which are attached to the top of the operating table by means of adhesive.

[0012] The beneficial effects of this utility model are as follows: By employing a combination of baffles, positioning pins, mounting plates, connecting plates, and fixing rods to restrict the position of the indentation rollers, the mounting plate's position is ensured to be stable when the baffle is on one side. Moving the moving frame until the baffle contacts the square plate, and then continuing to move the frame, the baffle can be moved away from one side of the mounting plate, thus releasing the restriction on the mounting plate. The mounting plate can then be removed from the positioning pins, and the indentation rollers replaced. After placing the mounting plate on the positioning pins, moving the moving frame away from the L-shaped plate causes the spring to extend, allowing the baffle to move to one side of the mounting plate, thus repositioning the mounting plate. This invention effectively addresses the limitations of existing carton creasing devices, which often make it difficult to replace creasing wheels. Different sizes of cartons generally require creasing wheels of corresponding specifications to ensure creasing quality. If the creasing wheels are difficult to disassemble and assemble, it will take a long time. Frequent replacements will cause production line downtime, thus affecting production efficiency. It also requires more manpower to complete this process, increasing labor input and operating costs. This invention effectively reduces the difficulty of disassembling and assembling creasing wheels, enabling quick replacement of creasing wheels, greatly improving the efficiency of creasing wheel replacement, and reducing downtime.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-5A creasing device for cardboard box production includes an operating table 1. A U-shaped frame 2 is mounted on the top of the operating table 1. Two fixing blocks 3 are fixedly connected to the inner walls of the top of both ends of the U-shaped frame 2. Two first guide rods 4 are fixedly connected to the two fixing blocks 3 at the same end on their adjacent sides. The two first guide rods 4 at the same end are fitted with the same first moving block 5. An L-shaped frame 6 is fixedly connected to the bottom of each of the two first moving blocks 5. A square groove 7 is opened at the adjacent ends of each of the two L-shaped frames 6. A second guide rod 8 is mounted in the square groove 7 and fixedly connected to the L-shaped frame 6. A second moving block 9 is mounted in the square groove 7 and fitted onto the second guide rod 8. The second moving block 9 slidably connects the second guide rod 8 and the L-shaped frame 6. A spring 10 is provided on one side of the second moving block 9, and the spring 10 is sleeved on the second guide rod 8. A baffle 35 is fixedly connected to the bottom of the second moving block 9. A mounting plate 11 is provided on one side of the baffle 35. Two positioning grooves 12 are opened on the mounting plate 11, and positioning pins 13 are provided in the positioning grooves 12. The two positioning pins 13 at the same end are fixedly connected to the same connecting plate 14. The connecting plate 14 is fixedly connected to the top inner wall of the L-shaped frame 6. A square plate 15 is provided on one side of the baffle 35. An L-shaped plate 16 is fixedly connected to the same side of the two square plates 15. The two L-shaped plates 16 are fixedly connected to the operating table 1. A U-shaped seat 17 is fixedly connected to the bottom of the two mounting plates 11. Bearings 18 are provided at both ends of the U-shaped seat 17. The outer ring of the bearing 18 is on the outer wall. A U-shaped seat 17 is fixedly connected. The inner walls of the inner rings of the two bearings 18 are fixedly connected to the same indentation wheel 19. A fixing rod 20 passes through the indentation wheel 19, and a hole adapted to the fixing rod 20 is opened on the indentation wheel 19. The fixing rod 20 is fixedly connected to the L-shaped frame 6. Due to the use of a baffle, positioning pin, mounting plate, connecting plate, and fixing rod to restrict the position of the indentation wheel, the position of the mounting plate can be ensured to be stable when the baffle is on one side of the mounting plate. When the moving frame is moved so that the baffle contacts the square plate, the baffle can be moved away from one side of the mounting plate by continuing to move the moving frame, thereby releasing the restriction on the mounting plate. The mounting plate can then be removed from the positioning pin, and the indentation wheel can be replaced. After the mounting plate is put on the positioning pin, the moving frame... Moving the plate away from the L-shaped plate causes the retracted spring to extend, allowing the baffle to move to one side of the mounting plate. This restricts the position of the mounting plate and effectively solves the problem mentioned in the background art: most existing carton creasing devices are inconvenient for replacing creasing wheels. Different sizes of cartons generally require creasing wheels of corresponding sizes to ensure creasing quality. If the creasing wheels are difficult to disassemble and assemble, it will take a long time. Frequent replacements will cause production line downtime, thus affecting production efficiency and requiring more manpower to complete this process, increasing labor input and operating costs. This technology effectively reduces the difficulty of disassembling and assembling creasing wheels, enables quick replacement of creasing wheels, greatly improves the efficiency of creasing wheel replacement, and reduces downtime.

The second electric push rod 24 is fixedly connected to the U-shaped frame 2, and the output end of the second electric push rod 24 passes through the U-shaped frame 2 and is fixedly connected to the L-shaped frame 6. Two fourth guide rods 25 are fixedly connected to the side of the L-shaped frame 6 near the second electric push rod 24. The fourth guide rods 25 pass through the U-shaped frame 2 and are slidably connected to the U-shaped frame 2. When the L-shaped frame 6 moves, it will drive the fourth guide rods 25 to move along the U-shaped frame 2, ensuring the stability of the L-shaped frame 6 when it moves.

[0020] In this embodiment, the operating table 1 is provided with an installation slot 26, and a U-shaped mounting bracket 27 is provided in the installation slot 26. The U-shaped mounting bracket 27 is fixedly connected to the operating table 1. A servo motor 28 is fixedly connected to one side of the U-shaped mounting bracket 27. A drive screw 29 is fixedly connected to the output end of the servo motor 28. A screw nut 30 is sleeved on the drive screw 29. The screw nut 30 is adapted to the drive screw 29. A movable seat 31 is fixedly connected to the outer wall of the screw nut 30. Movable frames 21 are fixedly connected to both sides of the movable seat 31. A fifth guide rod 32 is passed through both ends of the movable seat 31. The fifth guide rod 32 is fixedly connected to the U-shaped mounting bracket 27. The movable seat 31 is slidably connected to the fifth guide rod 32.

[0021] In this embodiment, the bottom inner walls of both ends of the movable frame 21 are fixedly connected to a third movable block 33, and a sixth guide rod 34 is passed through each of the two third movable blocks 33. The third movable blocks 33 are slidably connected to the sixth guide rod 34, and the two sixth guide rods 34 are fixedly connected to the operating table 1. When the movable frame 21 moves, it will drive the third movable blocks 33 to move along the sixth guide rod 34 to ensure the stability of the movable frame 21 when it moves.

[0022] In this embodiment, two indentation strips 36 are provided on the top of the operating table 1. The indentation strips 36 are attached to the top of the operating table 1 by adhesive. When it is necessary to replace the indentation strips 36 with other models, the indentation strips 36 can be directly peeled off, which also makes it easy to adjust the position of the indentation strips 36.

[0023] Working principle: When in use, an external power supply is used. The servo motor 28 is started by the external PLC controller. The output of the servo motor 28 drives the drive screw 29 to rotate, which in turn moves the screw nut 30. The screw nut 30 then moves the moving seat 31 along the fifth guide rod 32. The movement of the moving seat 31 moves the moving frame 21, which in turn moves the third moving block 33 along the sixth guide rod 34. The movement of the moving frame 21 moves the first electric push rod 22, which in turn moves the U-shaped frame 2. The U-shaped frame 2 moves the fixed block 3, which in turn moves the first guide rod 4. The first guide rod 4 then moves the first moving block 5. The first moving block 5 moves the L-shaped frame 6, which in turn moves the connecting plate 14. The connecting plate 14 moves the positioning pin 13, which in turn moves the mounting plate 11. The mounting plate 11 moves the U-shaped seat 17, which in turn moves the bearing 18. The bearing 18 in turn moves the creasing wheel 19. The creasing wheel 19, in conjunction with the creasing strip 36, creasing the cardboard. The first electric push rod 22 can be activated to extend its output end, thereby adjusting the height of the creasing wheel 19. The second electric push rod 24 can also be activated to extend its output end, thereby adjusting the position of the L-shaped frame 6, which in turn adjusts the lateral position of the creasing wheel 19. When adjusting the lateral position of the creasing wheel 19, the first electric push rod 22 can be activated to extend its output end, thereby adjusting the position of the L-shaped frame 6, which in turn adjusts the lateral position of the creasing wheel 19. The embossing strip 36 is peeled off from the workbench 1 and reattached to the workbench 1 directly below the embossing wheel 19. When the output end of the second electric push rod 24 moves the L-shaped frame 6, the L-shaped frame 6 will move the first moving block 5 along the first guide rod 4 to ensure the stability of the L-shaped frame 6 during movement. When it is necessary to remove the embossing wheel 19 and replace it with another specification of embossing wheel 19, the output ends of the first electric push rod 22 and the second electric push rod 24 are completely retracted, causing the output end of the servo motor 28 to rotate in the opposite direction, so that the moving frame 21 returns to its initial position. Due to the restriction of the square plate 15, the baffle 35 will contact the square plate 15. If the moving frame 21 continues to move, the baffle 35 and the second moving block 9 will not continue to move, which will cause... When the spring 10 contracts, the baffle 35 can be moved away from one side of the mounting plate 11, allowing the mounting plate 11 to be removed from the positioning pin 13. This allows the indentation wheel 19 to be removed from the fixing rod 20, enabling replacement of the indentation wheel 19. The indentation wheel 19, bearing 18, U-shaped seat 17, and mounting plate 11 are fixed together at the factory. The indentation wheel 19 is placed on the fixing rod 20, and the mounting plate 11 is placed on the two positioning pins 13 for positioning. Then, the moving frame 21 is moved away from the L-shaped plate 16 by a certain distance. The contracted spring 10 extends, allowing the baffle 35 to move to one side of the mounting plate 11, thus restricting the position of the mounting plate 11 and ensuring its stability. The indentation wheel 19 can then be installed.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
