[0027] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0028] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1 to 7 As shown, this utility model embodiment provides a corrugated cardboard box crease folding mechanism, which mainly includes a placement component 1, a folding component 2 for crease folding on the surface of the corrugated cardboard box, a detection component 3 for detecting the hardness of the corrugated cardboard box, and an adjustment component 4 for adjusting the pressure of the folding component 2.

[0030] Reference Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, the compression assembly 2 includes a power-driven mounting frame 21, on which a work box 22 is mounted. The work box 22 has an opening slot facing downwards, and a sponge block 23 is fixedly mounted at the top inside the opening slot. At the same time, a pipe connector 213 is connected to the mounting frame 21. The pipe connector 213 is suitable for connecting to an external water supply device to replenish water to the sponge block 23.

[0031] Furthermore, fixed plates 24 are fixedly installed at both ends of the working box 22. The side of the fixed plate 24 near the sponge block 23 has a hollow groove. A pressure rod 28 is movably arranged between the two sets of fixed plates 24. The pressure rod 28 has roller shafts 210 at both ends. The roller shafts 210 pass through the two sets of fixed plates 24. At the same time, a straight groove (not shown in the figure) is opened on the fixed plate 24, which is adapted to the diameter of the roller shaft 210 and allows the roller shaft 210 to move in the numerical direction. A fixing part 27 is sleeved on the roller shaft 210. The fixing part 27 has a guide rod 25. The guide rod 25 is used to guide the movement of the fixing part 27. A spring member 26 is fixedly installed at the top of the inner wall of the hollow groove. One end of the spring member 26 is connected to the fixing part 27, and the guide rod 25 is inside the spring member 26 and passes through the top of the fixed plate 24.

[0032] An external water supply device replenishes water to the sponge block 23 inside the working box 22 through pipe joint 213, keeping it moist. When it is necessary to fold or press materials (such as cardboard), the pressure bar 28 moves horizontally toward the sponge block 23 under the action of external driving force, and the rollers 210 at both ends slide vertically along the straight groove of the fixed plate 24.

[0033] When the pressure bar 28 contacts the material, the resistance of the material forces the roller 210 to move upward along the straight groove, compressing the spring 26 inside the hollow groove. The spring 26 exerts downward elastic pressure on the pressure bar 28 through the fixing part 27 and the guide rod 25, making the pressure bar 28 come into close contact with the material and applying flexible pressure. At this time, the sponge block 23 releases moisture to the material pressing position under the pressure of the pressure bar 28, assisting in softening the material for folding.

[0034] After the external force is removed, the elastic restoring force of the spring 26 pushes the guide rod 25 and the fixing part 27 to move down, driving the roller 210 to reset along the straight groove, and the pressure rod 28 disengages from the material, completing one pressing and bending action;

[0035] Meanwhile, a water receiving box 29 is fixedly installed on the pressure rod 28. There is a certain gap between the inner wall of the water receiving box 29 and the sponge block 23. The two sides of the water receiving box 29 are provided with a drain groove 211 for the water to flow out when the sponge block 23 is squeezed. The drain groove 211 is long and narrow, so the water when the sponge block 23 is squeezed first flows out through the drain groove 211 and then slides down the surface of the pressure rod 28 onto the corrugated cardboard box.

[0036] During the downward pressure of the pressure rod 28, the sponge block 23 is compressed, squeezing out its internal water. Because there is a gap between the inner wall of the water collection box 29 and the sponge block 23, and because the water collection box 29 has elongated drainage grooves 211 on both sides, the squeezed-out water first flows out through the drainage grooves 211, then slides down the surface of the pressure rod 28 to the area of ​​the corrugated cardboard box that needs to be folded. In this way, the water can be precisely applied to the folding area of ​​the corrugated cardboard box, softening the box locally and facilitating subsequent folding operations.

[0037] ReferenceFigure 2 As shown, a detection component 3 is installed on the side of the working box 22. The detection component 3 is used to detect the hardness of the corrugated cardboard box. The detection component 3 includes a second cylinder 31 fixedly installed on the side of the working box 22. The output end of the second cylinder 31 is equipped with a contact part 32 through a return spring. A pressure sensor is provided on the side of the contact part 32 near the second cylinder 31. The second cylinder 31 pushes the contact part 32 to move towards the corrugated cardboard box through the extension and retraction movement of the output end, so as to realize the approach or departure action of the contact part 32. When one end of the contact part 32 presses on the surface of the cardboard box, the peak reading of the pressure sensor can reflect the surface hardness of the cardboard box.

[0038] The second cylinder 31 acts as a power source, driving the contact part 32 to move towards or away from the corrugated cardboard box through the telescopic movement of its output end. When it is necessary to detect the cardboard box's hardness, the second cylinder 31 pushes the contact part 32 closer to the cardboard box at a constant speed. After the contact part 32 contacts the surface of the cardboard box, as the cylinder continues to advance, the reaction force from the cardboard box on the contact part 32 gradually increases. This force is transmitted to the pressure sensor on the back of the contact part 32 through a return spring. The pressure sensor monitors the reaction force in real time and converts it into an electrical signal. When the contact part 32 reaches the set stroke, the cylinder stops moving, and the peak reading of the pressure sensor at this time reflects the hardness of the cardboard box surface.

[0039] Reference Figure 6 As shown, an adjustment assembly 4 is installed on the work box 22. The adjustment assembly 4 includes a support plate 41 installed on the upper surface of the work box 22. A screw 42 is threadedly connected to the support plate 41. A concave structure baffle 44 is fixedly installed at one end of the screw 42. The baffle 44 is set through the 21 at both ends and has protruding ends at both ends. The protruding sections are set to fit against the side of the fixed plate 24. At the same time, an movable groove 212 for the baffle 44 to move is opened on the side of the mounting bracket 21. A scale 46 is set on the side of the fixed plate 24. The range of the scale 46 is from bottom to top (1cm-9cm).

[0040] It should be noted that, in the default state, one end of the protruding end is aligned with a certain mark on the scale 46. For example, when the compressive strength of the corrugated cardboard box is 2000N to 3000N, the protruding end is aligned with the center position on the scale 46. At this time, when the mounting bracket 21 driven by the power moves downward to drive the pressure rod 28 closer to the corrugated cardboard box, the pressure rod 28 contacts the surface of the corrugated cardboard box and moves downward as the power drive continues to push. At this time, the pressure rod 28 and the rollers 210 at both ends move upward and squeeze... Press the spring 26 until the roller 210 contacts the protruding end. At this time, the water collection box 29 on the pressure rod 28 exerts a certain linear pressure on the sponge block 23. The squeezed water flows out through the drain grooves 211 on both sides of the water collection box 29. When creasing corrugated boxes with different compressive strengths, the screw 42 can be rotated to drive the baffle 44 to move up and down in the movable groove 212, thereby indirectly adjusting the linear distance between one end of the protruding section and the roller 210 to adapt to different corrugated boxes for creasing.

[0041] For example, when the compressive strength of the corrugated cardboard box is 3000N to 4000N, the protruding end is aligned with the end of the scale 46 near the mounting bracket 21; when the compressive strength of the corrugated cardboard box is 1000N to 2000N, the protruding end is aligned with the end of the scale 46 away from the mounting bracket 21.

[0042] Furthermore, a turntable 43 is fixedly installed at one end of the screw 42, which facilitates the application of torque to the screw 42;

[0043] The working principle of the adjustment component 4 is as follows: The rotating turntable 43 drives the screw 42 to rotate, and the screw 42 moves axially via threaded transmission. This causes the baffle 44 to slide laterally within the movable groove 212 of the mounting frame 21 through its two protruding ends, thereby adjusting the relative position of the protruding ends and the scale 46 on the side of the fixed plate 24. The scale 46 (1cm-9cm range) is used to quantify the adjustment distance. By default, when the corrugated carton's compressive strength is 2000N-3000N, the protruding end is aligned with the center of the scale. When handling cartons with different compressive strengths, rotating the turntable 43 changes the position of the protruding end.

[0044] If the carton's compressive strength is 3000N-4000N, adjust the protruding end to be close to the scale of the mounting bracket 21 (e.g., 9cm), increase the initial distance between the roller shaft 210 and the protruding end, so that when the pressure bar 28 moves down, the roller shaft 210 needs to move up a longer distance to contact the protruding end, thereby increasing the compression of the spring 26 and increasing the squeezing force of the water receiving box 29 on the sponge block 23;

[0045] If the compressive strength is 1000N-2000N, adjust the protruding end to a mark away from the mounting frame 21 (e.g., 3cm) to shorten the distance between the roller 210 and the protruding end, reducing the compression and squeezing force of the spring 26. When the power-driven mounting frame 21 moves downward, after the pressure rod 28 contacts the carton, the roller 210 moves upward along the straight groove of the fixed plate 24 to squeeze the spring 26 until it contacts the protruding end. At this time, the water receiving box 29 squeezes the sponge block 23, and the water flows out through the drain trough 211 to the carton pressure line position. Through the linkage between the protruding end and the mark, the appropriate pressure and precise wetting of cartons with different hardness are achieved.

[0046] Working principle: The second cylinder 31 of the detection component 3 drives the contact part 32 to contact the carton. The pressure sensor monitors and feeds back the peak pressure data corresponding to the surface hardness of the carton in real time. The adjustment component 4 rotates the turntable 43 according to the detection results, and the screw 42 drives the baffle 44 to move laterally in the movable groove 212. The scale 46 is used to quantitatively adjust the initial distance between the protruding end of the baffle 44 and the roller shaft 210, thereby preset the compression stroke of the spring component 26. When the carton has high compressive strength (e.g., 3000N-4000N), the protruding end is adjusted to the scale close to the mounting frame 21 (e.g., 9cm) to increase the upward stroke of the roller shaft 210 and enhance the spring compression force; conversely, it is adjusted to the far end scale (e.g., 3cm) to reduce the pressure.

[0047] When the folding assembly 2 is working, the mounting frame 21 moves downward under power drive. After the pressure rod 28 contacts the carton, the roller 210 moves upward along the straight groove of the fixed plate 24 to compress the spring 26 until it contacts the protruding end of the baffle 44. At this time, the water receiving box 29 squeezes the sponge block 23, and the water flows precisely to the crease position through the drain trough 211 to assist in the softening and folding of the carton. The external water supply equipment continuously replenishes water to the sponge block 23 through the pipe joint 213. The elastic buffer of the spring 26 and the limiting of the baffle 44 together realize adaptive pressure and wetting for cartons of different hardness. The whole process improves the crease accuracy and folding efficiency through the closed-loop linkage of detection-adjustment-folding.

[0048] The detection component 3 quantifies the cardboard box's hardness (in Newtons) using a pressure sensor. The adjustment component 4, based on the detection data, precisely presets the compression stroke of the spring component 26 through a linkage between the screw 42, baffle 44, and scale. This ensures that high-hardness cardboard corresponds to a larger compression and water extraction amount from the spring component 26 (e.g., 3000N-4000N adjusted to a 9cm scale), while low-hardness cardboard receives less compression and water extraction (e.g., 1000N-2000N adjusted to a 3cm scale), avoiding the "one-size-fits-all" defects of traditional mechanical compression. The water collection box 29 and drain trough 211 further guide water precisely to the creasing position, improving wetting uniformity. The overall solution, through closed-loop control of "hardness sensing - parameter adjustment - flexible pressure application," significantly optimizes the creasing effect and folding quality of corrugated boxes with different hardness levels, reducing resource waste while improving the process stability of the production line.

[0049] Reference Figures 1-4 As shown, the placement component 1 includes a workbench 11, a support frame 12 is fixedly installed on the workbench 11, and an adjustment unit 13 is installed on the support frame 12. The adjustment unit 13 includes a concave frame 131 fixedly installed on the support frame 12 near the workbench 11. A lead screw 132 is connected to the concave frame 131 by a bearing. Limiting rods 133 are fixedly installed on the concave frame 131 at both sides of the lead screw 132. A sliding seat 135 is threadedly connected to the lead screw 132. The sliding seat 135 is movably sleeved on the two sets of limiting rods 133. The limiting rods 133 are suitable for linearly limiting the movement of the sliding seat 135. A motor 134 is fixedly installed on the side of the support frame 12. The output end of the motor 134 passes through the support frame 12, the concave frame 131 and is fixedly connected to the lead screw 132. A first cylinder 136 is fixedly installed on the sliding seat 135. A mounting bracket 21 is fixedly installed on the output end of the first cylinder 136.

[0050] Motor 134 drives lead screw 132 to rotate within concave frame 131, which in turn drives sliding seat 135 to move laterally along limiting rod 133 via threaded transmission, thus achieving lateral positioning of mounting bracket 21. Limiting rod 133 ensures the straightness and stability of sliding seat 135's movement. When the height of the pressing and bending assembly 2 needs to be adjusted, the first cylinder 136 on sliding seat 135 drives mounting bracket 21 to move vertically up or down via piston rod extension and retraction, bringing it closer to or away from worktable 11.

[0051] During operation, the motor 134 first drives the sliding seat 135 to the lateral coordinate corresponding to the carton's crease position. Then, the first cylinder 136 controls the mounting frame to move downwards, causing the pressure rod 28 to contact the carton surface. This, combined with subsequent detection, adjustment, and folding actions, completes the operation. This structure, through the high-precision positioning driven by the lead screw 132 and the controllable lifting of the cylinder, achieves multi-dimensional adaptive adjustment for cartons of different specifications, improving the automation level and positional accuracy of crease folding.
