[0034] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0035] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0036] Reference Figures 1-9 As shown, a cardboard box folding device includes: two sets of limiting seats 101 that are slidably disposed relative to each other within a base 100 and whose spacing is adjustable via a limiting adjustment mechanism 200; a conveyor belt 102 for conveying cardboard is driven by a drive motor 103 on the limiting seats 101; wherein,

[0037] A bracket 105 is fixedly provided on the base 100. A crease plate 104 with adjustable spacing and which can be raised and lowered along the vertical direction of the bracket 105 is provided on the bracket 105 through a crease adjustment mechanism 300.

[0038] In operation, the distance between the two sets of limit seats 101 is adjusted by the limit adjustment mechanism 200 according to the width of the cardboard to be processed, ensuring that the cardboard can be stably conveyed by the conveyor belt 102. The drive motor 103 is started, and the drive motor 103 drives the conveyor belt 102 to start running. The cardboard to be processed is placed on the conveyor belt 102, and the cardboard moves forward with the conveyor belt 102. According to the thickness of the cardboard and the required crease depth, the distance between the crease plate 104 and the conveyor belt 102, as well as the vertical position of the crease plate 104 on the support 105, is adjusted by the crease adjustment mechanism 300. When the cardboard moves with the conveyor belt 102 to below the crease plate 104, the cardboard is pressed into the required crease by the crease plate 104. After the crease is completed, the cardboard continues to move forward with the conveyor belt 102 until it leaves the device. Through the adjustment of the limit adjustment mechanism 200 and the crease adjustment mechanism 300, the device can adapt to the processing needs of cardboard of different widths and thicknesses, improving the versatility and flexibility of the equipment.

[0039] Reference Figures 1-4 As shown, the limit adjustment mechanism 200 includes: a mounting plate 202, a support base 203, and a servo motor 204; wherein,

[0040] The base 100 has multiple sets of limiting slide grooves 201 spaced apart. Two sets of mounting plates 202 are slidably arranged opposite each other with adjustable spacing inside the base 100. A support base 203 is fixedly mounted on the mounting plate 202 and slides with the limiting slide grooves 201. The limiting base 101 is fixedly mounted on the support base 203. An adjusting component for adjusting the two sets of mounting plates 202 is fixedly mounted inside the base 100.

[0041] In the above scheme, when it is necessary to adjust the distance between the two sets of limit seats 101, the adjusting component is activated to adjust the distance between the two sets of limit seats 101. When the distance is adjusted to the required value, the adjusting component stops working, and the mounting plate 202 and the limit seats 101 remain in the current position, ready for cardboard feeding and crease processing. Through the precise control of the adjusting component, the distance between the mounting plate 202 and the limit seats 101 can be precisely adjusted to meet the processing requirements of cardboard of different widths.

[0042] Reference Figures 4-6 As shown, the adjusting component includes: a servo motor 204, a turntable 205, and a drive rod 206; wherein,

[0043] A servo motor 204 is fixedly installed on the inner bottom wall of the base 100. The output shaft of the servo motor 204 is vertically upward and a turntable 205 is fixedly installed at its top. Drive rods 206 are respectively hinged to both ends of the turntable 205. One end of the drive rod 206 is hinged to the mounting plate 202.

[0044] In the above scheme, when it is necessary to adjust the position of the mounting plate 202 and the limiting seat 101, the servo motor 204 is started, and the output shaft of the servo motor 204 drives the turntable 205 to rotate. The rotation angle and direction of the turntable 205 are determined by the control signal of the servo motor 204. The rotation of the turntable 205 is converted into the sliding of the mounting plate 202 in the base 100 through the hinged drive rod 206. Since the drive rod 206 is hinged to both the turntable 205 and the mounting plate 202, the rotation of the turntable 205 will cause the mounting plate 202 to move in a specific direction in the limiting slide groove 201. With the transmission of the drive rod 206, the mounting plate 202 and the limiting seat 101 on the support base 203 slide in the base 100 until the desired position is reached. When the mounting plate 202 and the limiting seat 101 have moved to the desired position, the servo motor 204 stops working, and the mounting plate 202 remains in the current position, ready for subsequent cardboard processing operations.

[0045] Reference Figure 4 As shown, the bottom surface of the mounting plate 202 is provided with multiple sets of rollers 207 that rotatably contact the bottom wall of the base 100.

[0046] In the above scheme, during the movement of the mounting plate 202, the rollers 207 on the bottom surface roll on the bottom wall of the base 100, which reduces the frictional resistance between the mounting plate 202 and the base 100, allowing the mounting plate 202 to move more smoothly and stably.

[0047] Reference Figures 2-9 As shown, the crease adjustment mechanism 300 includes: a hydraulic rod 301, a mounting bracket 302, a bidirectional screw 303, and a threaded block 307; wherein,

[0048] A hydraulic rod 301 is fixedly mounted on the bracket 105. The output end of the hydraulic rod 301 is vertically downward and fixedly connected to a mounting bracket 302. A bidirectional screw 303 is rotatably mounted inside the mounting bracket 302. The bidirectional screw 303 has two sections of threads with opposite directions, and each section of thread is threaded with a threaded block 307. A crease plate 104 is fixedly mounted on the bottom surface of the threaded block 307. A limiting rod 306 parallel to the bidirectional screw 303 is also fixedly mounted inside the mounting bracket 302, and the threaded block 307 slides through the limiting rod 306. A rotary motor 304 with an output shaft fixedly connected to the bidirectional screw 303 is fixedly mounted on the mounting bracket 302. A clearance groove 305 is provided on the bracket 105 for the rotary motor 304 to slide.

[0049] In the above scheme, the hydraulic rod 301 is activated according to the thickness of the cardboard, and its output end extends, driving the mounting frame 302 and the bidirectional screw 303 to move vertically downward. As the hydraulic rod 301 extends, the crease plate 104 gradually approaches the conveyor belt 102. When the hydraulic rod 301 extends to the required height, the rotary motor 304 is activated. The output shaft of the rotary motor 304 drives the bidirectional screw 303 to rotate. Since the bidirectional screw 303 has two sections of threads with opposite directions, as the bidirectional screw 303 rotates, the two threaded blocks 307 will move towards or away from each other, thereby adjusting the distance between the two crease plates 104. During the movement of the threaded blocks 307, the limiting rod 306 plays a role in assisting sliding and limiting. The threaded blocks 307 slide on the limiting rod 306, ensuring the smoothness and accuracy of the movement. When the crease plate 104 is adjusted to the required position, the rotary motor 304 and the hydraulic rod 301 stop working. At this point, the crease plate 104 remains in its current position, ready for cardboard crease processing.

[0050] Reference Figure 7 As shown, the sides of the two sets of limiting seats 101 are respectively provided with limiting components 400 for limiting the cardboard when creases are formed.

[0051] In use, the cardboard is conveyed to the limit seats 101 via the conveyor belt 102. When the cardboard reaches the position of the limit seat 101, the limit component 400 starts to function to limit the cardboard and prevent the cardboard from shifting during the crease process. Under the limiting action of the limit component 400, the cardboard passes stably through the crease plate 104 to form the required crease.

[0052] Reference Figures 5-8 As shown, the limiting assembly 400 includes: a connecting rod 401, a limiting plate 402, and a return spring 404; wherein,

[0053] The base 100 has multiple mounting slots 403 spaced apart on its side. Each mounting slot 403 is provided with a return spring 404. One end of the return spring 404 is fixedly connected to a sliding block 405 that slides with the side wall of the mounting slot 403. A connecting rod 401 is fixedly installed on the sliding block 405. One end of the connecting rod 401 is fixedly provided with a limiting plate 402 whose side contacts the side wall of the cardboard.

[0054] In the above scheme, when the cardboard is conveyed to the limiting seats 101 via the conveyor belt 102, the side of the cardboard first contacts the limiting plate 402. Under the action of the cardboard, the limiting plate 402 drives the sliding block 405 to move outward in the mounting groove 403 via the connecting rod 401, stretching the return spring 404. After being stretched, the return spring 404 generates a reaction force, pulling the sliding block 405, the connecting rod 401, and the limiting plate 402 inward, so that the limiting plate 402 is tightly pressed against the side of the paperboard, limiting the cardboard. Under the limiting action of the limiting plate 402, the cardboard stably passes through the crease plate 104, completing the crease processing. The limiting assembly 400, through the adaptive adjustment of the return spring 404, can limit cardboard of different widths, improving the flexibility and adaptability of the equipment.

[0055] Reference Figure 5 and Figure 6 As shown, the limiting plate 402 has an inclined surface on the side near the feed end of the conveyor belt 102.

[0056] In the above scheme, when the cardboard is conveyed to the limiting seat 101 by the conveyor belt 102, the side of the cardboard first contacts the inclined surface of the limiting plate 402 near the feeding end of the conveyor belt 102. The inclined surface design makes it easier for the cardboard to enter the limiting range of the limiting plate 402, avoiding jamming or damage to the cardboard when it contacts the limiting plate 402.

[0057] In summary, the cardboard folding device provided by this utility model involves placing the cardboard to be folded on the conveyor belt 102, ensuring that both ends of the cardboard are aligned with the limiting seats 101. The distance between the two sets of limiting seats 101 is adjusted according to the width of the cardboard via the limiting adjustment mechanism 200 to ensure the cardboard remains stable during transport. The drive motor 103 is then started, and its output shaft drives the conveyor belt 102 to transport the cardboard from the inlet to the outlet. During transport, the limiting plate 402 of the limiting component 400 contacts the side of the cardboard, limiting its movement and preventing it from shifting during transport. The inclined surface design of the limiting plate 402 helps the cardboard smoothly enter the limiting area. According to the thickness of the cardboard and the crease requirements, the spacing and height of the crease plates 104 are adjusted by the crease adjustment mechanism 300. The hydraulic rod 301 is activated, and the output end of the hydraulic rod 301 drives the mounting frame 302 to rise and fall, thereby adjusting the height of the crease plates 104. The rotary motor 304 is activated, and the output shaft of the rotary motor 304 drives the bidirectional screw 303 to rotate. Since the bidirectional screw 303 has two sections of threads with opposite directions, the threaded block 307 will move along the bidirectional screw 303 in opposite directions, thereby adjusting the spacing of the crease plates 104. When the cardboard is conveyed to the area below the crease plates 104, the crease plates 104 perform creasing treatment on the cardboard to form the required creases.
