Technical Field

[0001] This utility model relates to the field of corrugated cardboard box creasing technology, and more specifically, to a device for adjusting the creasing depth of corrugated cardboard boxes. Background Technology

[0002] Corrugated boxes are made from corrugated cardboard through processes such as die-cutting, creasing, nailing, or gluing. Among these processes, creasing is one of the most important manufacturing steps. During the production and processing of corrugated boxes, a creasing device is used to pre-crease the corrugated cardboard to facilitate folding later.

[0003] A search revealed that Chinese patent CN219276842U discloses an adjustable corrugated cardboard creasing device. This structure uses a thickness gauge to measure the thickness of the corrugated cardboard, and then uses a controller, a drive unit and a laser rangefinder to work together to accurately limit and fix the corrugated cardboard.

[0004] However, in actual use, since several creasing blocks are fixed on the transmission rod, it is difficult to accurately adjust the spacing between each adjacent creasing block according to the spacing of the creasing of the corrugated cardboard, resulting in low adaptability. In view of this, this utility model proposes a device for adjusting the creasing depth of corrugated cardboard boxes. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a corrugated carton indentation depth adjustable device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable corrugated carton creasing depth device, including a base plate, a support frame fixedly installed on the surface of the base plate, a concave frame fixedly installed at the center of the surface of the base plate, and an upper concave frame symmetrically arranged on the top of the concave frame.

[0007] To achieve precise adjustment of the creasing roller spacing according to the needs of corrugated boxes and ensure consistent adjustment distances across multiple creasing rollers, while simultaneously using a servo motor to drive the creasing rollers to complete the creasing operation, preferably, both the upper and lower concave frames are equipped with a roller adjustment structure. This structure includes a rectangular shaft rotatably mounted inside the upper and lower concave frames. Several rectangular sleeves are slidably mounted on the outside of the rectangular shaft, and creasing rollers are fixedly mounted on the outside of each sleeve. The surface of the rectangular shaft has an array of positioning holes, and each of the rectangular sleeves is connected to two threaded sleeves. Positioning screws are provided inside the threaded sleeves. The positioning bolt has its outer wall threaded into the inner wall of the threaded sleeve, and is threaded into the positioning hole on the surface of the rectangular shaft. A servo motor is provided at one end of the rectangular shaft. The servo motor is fixedly installed on the outer wall of the corresponding upper and lower concave frames, and the output end of the servo motor is fixedly connected to the rectangular shaft. A measuring scale is provided inside the upper and lower concave frames and on one side of the corresponding rectangular shaft. An indicator ring is slidably installed on the surface of the measuring scale. Two limit plates are provided on the top of the indicator ring. Both ends of the measuring scale are fixedly installed inside the upper and lower concave frames, and the indentation wheel is located between the two limit plates.

[0008] In order to drive the upper concave frame to move up and down by means of an electric push rod and achieve stable guidance by means of a connecting rod and a sliding rod, thereby adjusting the distance between the upper and lower creasing wheels to adapt to corrugated boxes of different thicknesses and precisely controlling the creasing depth, preferably, an electric push rod is fixedly installed on the support frame, the output end of the electric push rod extends into the interior of the support frame and is fixedly connected to the upper surface of the upper concave frame, and sliding grooves are opened on both sides of the inner wall of the support frame, a sliding rod is fixedly installed inside the sliding groove, and a connecting rod is slidably installed outside the sliding rod, and the two connecting rods are respectively fixedly installed on both sides of the outer wall of the upper concave frame.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] 1. By setting up a pressure roller adjustment structure, the spacing between the pressure rollers can be flexibly adjusted by sliding the rectangular sleeve on the rectangular shaft. With the help of the measuring ruler and the indicator ring, the spacing size can be accurately controlled and the consistency of the adjustment of multiple pressure rollers can be ensured. At the same time, the rectangular mating structure between the rectangular shaft and the rectangular sleeve ensures that the pressure rollers rotate stably when driven by the servo motor, realizing accurate pressure creasing of corrugated boxes of different specifications, improving the adaptability of the device and the pressure creasing quality.

[0011] 2. The upper concave frame is driven up and down by an electric push rod. Combined with the guiding effect of the slide rod in the slide groove on the connecting rod, the upper concave frame is raised and lowered smoothly to adjust the distance between the upper and lower creasing wheels. This not only allows for precise control of the creasing depth but also adapts to the creasing requirements of corrugated boxes of different thicknesses, enhancing the adjustment flexibility and operational stability of the device.

[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] As attached Figure 1-5 The corrugated cardboard box indentation depth adjustable device shown includes a base plate 1, a support frame 2 fixedly installed on the surface of the base plate 1, a concave frame 3 fixedly installed at the center of the surface of the base plate 1, and an upper concave frame 4 symmetrically arranged on the top of the concave frame 3.

[0020] In this embodiment, as shown in the appendix Figure 1 , 2As shown in Figures 3 and 4, both the upper concave frame 4 and the lower concave frame 3 are equipped with pressure roller adjustment structures. Each pressure roller adjustment structure includes a rectangular shaft 5 rotatably mounted inside the upper concave frame 4 and the lower concave frame 3. Several rectangular sleeves 6 are slidably mounted on the outside of the rectangular shaft 5. Indentation wheels 7 are fixedly mounted on the outside of the rectangular sleeves 6. Several positioning holes 8 are arrayed on the surface of the rectangular shaft 5. Two threaded sleeves 9 are connected to the surface of each of the rectangular sleeves 6. Positioning bolts 10 are installed inside the threaded sleeves 9. The outer wall of the positioning bolts 10 is threadedly engaged with the inner wall of the threaded sleeves. The positioning bolts 10 and the rectangular shaft 5 are also threaded together. The positioning hole 8 on the surface of the rod 5 is threaded. A servo motor 11 is provided at one end of the rectangular shaft 5. The servo motor 11 is fixedly installed on the outer wall of the corresponding upper concave frame 4 and lower concave frame 3, and the output end of the servo motor 11 is fixedly connected to the rectangular shaft 5. A measuring ruler 12 is provided inside the upper concave frame 4 and lower concave frame 3 and on one side of the corresponding rectangular shaft 5. An indicator ring 13 is slidably installed on the surface of the measuring ruler 12. Two limit plates 14 are provided on the top of the indicator ring 13. The two ends of the measuring ruler 12 are fixedly installed inside the upper concave frame 4 and lower concave frame 3. The indentation wheel 7 is located between the two limit plates 14.

[0021] Specifically, the principle of this structure is as follows: the spacing between several creasing wheels 7 is adjusted according to the creasing spacing of the corrugated cardboard box. The rectangular sleeve 6 slides outside the rectangular shaft 5, driving the outer creasing wheels 7 to move. This is used to adjust the distance between every two creasing wheels 7 according to the creasing spacing of the corrugated cardboard box. After the spacing of the creasing wheels 7 is adjusted, the positioning bolt 10 is rotated, causing the positioning bolt 10 to rotate inside the threaded sleeve and extend into the positioning hole 8 on the surface of the rectangular shaft 5. This makes the positioning bolt 10 threadedly limit the positioning hole 8, thereby fixing the adjusted creasing wheels 7.

[0022] During the sliding adjustment of the indentation wheel 7, the indicator ring 13 is driven to slide on the surface of the measuring ruler 12 under the action of the two limit plates 14. This is used to measure the distance between the two indentation wheels 7, ensuring the accuracy of the adjustment, and ensuring that the adjustment distance of several indentation wheels 7 inside the upper concave frame 4 and the lower concave frame 3 is consistent, thereby improving the indentation effect.

[0023] During creasing, the corrugated cardboard is positioned between the creasing wheels 7 inside the upper concave frame 4 and the lower concave frame 3. The servo motor 11 is controlled by the PLC. The upper and lower creasing wheels 7 rotate at the same speed but in opposite directions. At this time, the servo motor 11 drives the corresponding rectangular shafts 5 inside the upper concave frame 4 and the lower concave frame 3 to rotate in opposite directions. Since the inner wall of the rectangular sleeve 6 and the outer wall of the rectangular shaft 5 are both rectangular, the rotation of the rectangular shaft 5 can drive the rectangular sleeve 6 to rotate, thereby causing the external creasing wheels 7 to rotate. The creasing wheels 7 can rotate between the two limiting plates 14 to perform the creasing operation on the corrugated cardboard.

[0024] In this embodiment, as shown in the appendix Figure 1 , 5 As shown, an electric push rod 15 is fixedly installed on the support frame 2. The output end of the electric push rod 15 extends into the interior of the support frame 2 and is fixedly connected to the upper surface of the upper concave frame 4. Slide grooves 16 are provided on both sides of the inner wall of the support frame 2. A slide rod 17 is fixedly installed inside the slide groove 16. A connecting rod 18 is slidably installed outside the slide rod 17. The two connecting rods 18 are fixedly installed on both sides of the outer wall of the upper concave frame 4.

[0025] Specifically, in this structure, when adjusting the creasing depth of the corrugated carton, the electric push rod 15 drives the upper concave frame 4 to extend downward, so that the connecting rods 18 at both ends of the upper concave frame 4 slide and guide outside the slide rod 17 in the slide groove 16, thereby adjusting the distance between the creasing wheels 7 in the upper concave frame 4 and the lower concave frame 3, which can adjust the creasing depth of the corrugated carton and facilitate the creasing operation of corrugated cartons of different thicknesses.

[0026] Working principle of this utility model:

[0027] This application provides an adjustable creasing depth device for corrugated cardboard boxes. In specific use, according to the required creasing spacing of the corrugated cardboard box, the position of the sliding rectangular sleeve 6 on the rectangular shaft 5 is adjusted, which drives the external creasing wheels 7 to move synchronously, thereby adjusting the distance between adjacent creasing wheels 7. During the adjustment process, the creasing wheels 7 will drive the indicator ring 13 to slide on the measuring ruler 12 through the limit plates 14 on both sides. The position of the indicator ring 13 can accurately measure the spacing of the creasing wheels 7, ensuring that the adjustment distance of multiple creasing wheels 7 is consistent. After the spacing is determined, the positioning bolt 10 inside the threaded sleeve 9 is rotated to extend to the corresponding positioning hole 8 on the surface of the rectangular shaft 5 and threaded connection, thereby fixing the rectangular sleeve 6 and the creasing wheels 7.

[0028] When the electric push rod 15 on the support frame 2 is activated, its output end drives the upper concave frame 4 to move up and down. At this time, the connecting rods 18 on both sides of the upper concave frame 4 will slide along the sliding rod 17 in the sliding groove 16 on the inner wall of the support frame 2, thereby guiding the upper concave frame 4. By adjusting the distance between the upper concave frame 4 and the lower concave frame 3, the distance between the corresponding upper and lower creasing wheels 7 can be changed, thereby adapting to the creasing requirements of corrugated boxes of different thicknesses and precisely adjusting the creasing depth.

[0029] The corrugated cardboard is placed between the creasing wheels 7 in the upper concave frame 4 and the lower concave frame 3. The servo motor 11 is started, and the servo motor 11 drives the rectangular shafts 5 in the upper concave frame 4 and the lower concave frame 3 to rotate in opposite directions. Since the rectangular sleeve 6 and the rectangular shaft 5 have a rectangular mating structure, the rotation of the rectangular shaft 5 will drive the rectangular sleeve 6 and the external creasing wheels 7 to rotate synchronously. When the creasing wheels 7 rotate between the two side limit plates 14, they creasing the corrugated cardboard sandwiched in the middle, thus completing the creasing operation.
