Description

Technical Field

[0001] This utility model relates to the field of packaging carton production technology, specifically a cardboard creasing device for packaging cartons. Background Technology

[0002] In the packaging carton manufacturing industry, cardboard creasing is a crucial process that determines the folding precision and forming quality of the carton. Its positioning accuracy, creasing precision, and ease of operation directly affect subsequent processing efficiency and product quality. Traditional cardboard creasing devices have several significant shortcomings in practical applications:

[0003] First, the cardboard positioning and fixing methods are simplistic and lack stability. Traditional equipment often uses mechanical clamps or manual pressing to fix the cardboard. For cardboard of different sizes, the clamp position needs to be adjusted frequently, which is cumbersome and prone to displacement of the cardboard during the creasing process due to uneven clamping force. This results in creasing lines that are off-center and of varying depths, affecting the sealing and aesthetics of the folded carton.

[0004] Secondly, the creasing mechanism lacks flexibility in adjustment. Traditional creasing wheels are mostly fixed, making it difficult to quickly adjust their position and pressure according to the size of the cardboard or the creasing requirements. When processing cardboard of different specifications, it is necessary to replace the entire creasing assembly or even the equipment, which is time-consuming and labor-intensive, and cannot meet the high-efficiency requirements of small-batch, multi-specification production.

[0005] Furthermore, the post-crimping material removal operation is inconvenient. Traditional equipment lacks an automatic unloading structure, requiring operators to manually remove the cardboard from the crimping station. This is not only time-consuming and labor-intensive, but may also cause damage due to the cardboard sticking to or jamming with the equipment. This is especially true for large or multi-layered cardboard, where the material removal efficiency is low and production continuity is easily affected.

[0006] To address the aforementioned issues, there is an urgent need to design a cardboard creasing device with flexible positioning, precise creasing, and convenient unloading functions. This would solve problems such as unstable fixing, limited adjustment, and inconvenient material handling in traditional equipment, and meet the packaging industry's demand for efficient and precise cardboard creasing processes. Utility Model Content

[0007] In order to solve the problems mentioned in the background art, the present invention provides a cardboard creasing device for packaging cartons.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A cardboard creasing device for packaging cartons includes a carton body, a movable creasing wheel, and a servo motor. The movable creasing wheel is installed on the inner top wall of the carton body. The servo motor is fixedly connected to the top of the carton body. A lead screw is fixedly connected to the drive end of the servo motor. A placement plate is threaded onto the outer surface of the lead screw. A placement groove is formed on the top of the placement plate, which is located directly below the movable creasing wheel. A material plate is placed inside the placement groove, and the material plate is in contact with the inner bottom wall of the placement groove. A support rod is fixedly connected to the bottom of the material plate, passing through the placement plate and extending below it. A support plate is fixedly connected to the bottom end of the support rod. A connecting plate is provided on the top of the carton body. Two connecting rods are fixedly connected to the bottom of the connecting plate. Both connecting rods pass through the top of the carton body and extend into the interior of the carton body. The two connecting rods are located in front of and behind the movable creasing wheel, respectively. A pressure plate is fixedly connected to the bottom end of each of the two connecting rods, and both pressure plates are located directly above the placement plate.

[0010] Preferably, the support plate is located above the inner bottom wall of the box.

[0011] Preferably, the two side walls of the placement plate are in contact with the two inner walls of the box, respectively.

[0012] Preferably, both the placement plate and the pressure plate are equipped with permanent magnets.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The device employs a linkage positioning structure combining permanent magnet adsorption and servo motor drive. A lead screw lifts the placement plate to the pressure plate position, and the magnetic force of the permanent magnet clamps cardboard of different sizes, replacing the cumbersome adjustment process of traditional mechanical fixtures. This ensures no displacement of the cardboard during creasing, solving the problem of creasing deviation caused by unstable positioning and improving creasing accuracy and consistency. The coordinated design of the movable creasing wheel and lead screw drive system allows the creasing wheel to be quickly adjusted along a straight line according to the cardboard size. It can adapt to different creasing requirements without changing components, overcoming the limitations of traditional fixed creasing wheels. The same drive system achieves the dual functions of lifting the placement plate and moving the creasing wheel, significantly improving the processing flexibility and production efficiency of the device. The coordinated unloading structure of the support plate, support rod and material plate, after the creasing is completed, the continued descent of the placement plate triggers the support plate to contact the bottom wall of the box, thereby pushing the material plate to push the cardboard out of the placement slot, realizing automatic unloading. This avoids the time-consuming and labor-intensive problems of traditional manual material handling and the problem of cardboard damage. The creasing and unloading actions are completed using the same drive path, simplifying the operation process and improving production continuity. Attached Figure Description

[0017] Example

[0018] Please see Figure 1 A cardboard creasing device for packaging cartons includes a carton body 1, a movable creasing wheel 2, and a servo motor 3. The movable creasing wheel 2 is installed on the inner top wall of the carton body 1. The servo motor 3 is fixedly connected to the top of the carton body 1. A lead screw 4 is fixedly connected to the drive end of the servo motor 3. A placement plate 5 is threaded onto the outer surface of the lead screw 4. A placement groove 6 is formed on the top of the placement plate 5. The placement groove 6 is located directly below the movable creasing wheel 2. A material plate 7 is disposed inside the placement groove 6. The material plate 7 is in contact with the inner bottom wall of the placement groove 6. A support rod 8 is fixedly connected to the bottom, the support rod 8 passes through the placement plate 5 and extends to the bottom of the placement plate 5, and a support plate 9 is fixedly connected to the bottom end of the support rod 8. A connecting plate 10 is provided on the top of the box body 1, and two connecting rods 11 are fixedly connected to the bottom of the connecting plate 10. Both connecting rods 11 pass through the top of the box body 1 and extend into the interior of the box body 1. The two connecting rods 11 are located in front and behind the movable indentation wheel 2, respectively. A pressure plate 12 is fixedly connected to the bottom end of both connecting rods 11, and both pressure plates 12 are located directly above the placement plate 5.

[0019] The position design of the support plate 9 ensures that it contacts the bottom wall of the box 1 first during the descent of the placement plate 5. The support rod 8 stably lifts the material plate 7, avoiding motion interference caused by the support plate 9 being directly embedded in the bottom wall of the box. This ensures that the cardboard is subjected to force during unloading, prevents the cardboard from tilting or breaking due to unstable support, and further improves the reliability and stability of the material handling process.

[0020] The fitting design between the placement plate 5 and the inner wall of the box 1 forms a linear guide structure. When the servo motor 3 drives the lead screw 4 to lift the placement plate 5, it effectively limits its lateral displacement, ensuring that the placement plate 5 moves accurately in the vertical direction and avoiding cardboard positioning deviation caused by shaking. Combined with the magnetic fixation of the pressure plate 12, it further improves the stability of the cardboard during the creasing process and ensures the accuracy and consistency of the creasing line.

[0021] By using the magnetic attraction of permanent magnets to replace the traditional mechanical clamping structure, when the placement plate 5 rises to contact the pressure plate 12, the cardboard can be tightly attracted and fixed by magnetic force without additional power. It is suitable for cardboard of different thicknesses and sizes, and solves the problem of frequent adjustment required by traditional clamps.

[0022] The working principle of this utility model is as follows: When using the cardboard creasing device for packaging cartons, the operator first adjusts the position of the movable creasing wheel 2 according to the size of the cardboard to be creasing, and then puts the cardboard into the box body 1, so that the cardboard is placed in the placement groove 6 of the placement plate 5 and laid flat on the top of the material plate 7; the servo motor 3 is started to drive the lead screw 4 to rotate, which drives the placement plate 5 to move upward along the inner wall of the box body 1 until the placement plate 5 contacts the pressure plate 12. Since both the placement plate 5 and the pressure plate 12 are equipped with permanent magnets, the two clamp and fix the cardboard in the placement groove 6 through magnetic attraction. Servo motor 3 continues to drive the placement plate 5 upward, so that the cardboard contacts the movable creasing wheel 2. The creasing wheel 2 presses the required marks on the surface of the cardboard by moving in a straight line. After the creasing is completed, servo motor 3 rotates in the opposite direction, the placement plate 5 moves downward and separates from the pressure plate 12, and the cardboard is released from the fixation. The placement plate 5 continues to descend until the support plate 9 contacts the bottom wall of the box 1. At this time, the bottom wall of the box 1 lifts the material plate 7 upward through the support plate 9 and the support rod 8, so that the cardboard on the top of the material plate 7 is removed from the placement slot 6, making it easy for the operator to remove the creasing cardboard.
