[0002] Packaging boxes are common items made by folding cardboard. Current technology uses folding machines to replace manual labor, improving folding efficiency and quality. However, existing folding machines have the following problems: Taking a square packaging box as an example, the folding machine performs two folds. The first fold folds two opposite sides of the box, and the second fold folds the remaining two opposite sides. During the second fold, the machine folds twice, causing the opposite sides of the second fold to clamp the opposite sides of the first fold. However, because cardboard has a certain elasticity, the cardboard springs back after the second fold, requiring manual intervention, which reduces folding efficiency. Utility Model Content

[0026] Example This embodiment provides a packaging cardboard folding device, such as... Figures 1-6 As shown, a packaging cardboard folding device includes a workbench 100, a conveying module 200, a positioning detection module 300, and a folding module 400. The conveying module 200, the arrival detection module 300, and the folding module 400 are all set on the workbench 100. The conveying module 200 is used to convey the packaging cardboard, the arrival detection module 300 is used to detect whether the packaging cardboard is in place, and the folding module 400 is telescopically set on the workbench 100 and is used to fold the packaging cardboard. A pressing module 500 is provided above the workbench 100. The pressing module 500 includes a base 501, pressing rods 502 and an elastic plate 503. The base 501 has a lifting function. Several pressing rods 502 are provided and form a frame structure adapted to the packaging cardboard. The pressing rods 502 are all slidably set on the bottom surface of the base 501 to adjust the size of the frame structure. Two adjacent telescopic pressing rods 502 are connected by an elastic plate 503. Correspondingly, the workbench 100 is provided with a folding area 101 adapted to the frame structure.

[0027] For the packaging paperboard folding device, the workbench 100, conveying module 200, arrival detection module 300 and folding module 400 cooperate with each other to complete the conveying, arrival detection and folding of the packaging paperboard. After folding, the pressing module 500 performs a pressing operation to reduce or even eliminate the rebound of the packaging paperboard. Specifically, after the packaging paperboard is folded, the pressure rod 502 slides and forms a frame structure that fits the packaging paperboard. The elastic plate 503 deforms appropriately, and the base 501 descends, allowing the pressure rod 502 and the elastic plate 503 to be inserted into the folded packaging paperboard. The pressure rod 502 and the elastic plate 503 cooperate with each other to press the folded edge of the packaging paperboard, reducing or even eliminating the rebound of the packaging paperboard.

[0028] Furthermore, the pressure bar 502 is slidably mounted on the base 501. The size of the frame structure can be adjusted by sliding the pressure bar 502. On the one hand, this makes the pressure module 500 suitable for packaging paperboard of different sizes, thus expanding its application range. On the other hand, it also makes the pressure module 500 used to fix the packaging paperboard in the folding operation, thus enriching its functions.

[0029] The elastic plate 503 adapts to the sliding of the pressure bar 502 through elastic deformation to ensure the effective pressure on the packaging cardboard. It is easy to understand that the elastic plate 503 can be made from any suitable existing board material or any suitable material.

[0030] For the base 501, the base 501 is provided with a drive mechanism 600 for sliding the pressure rod 502. The drive mechanism 600 includes a fixed plate 601, a threaded cylinder 602, a drive rod 603, a sleeve 604, a transmission rod 605, and a transmission plate 606. The fixed plate 601 is fixed on the base 501. One end of the threaded cylinder 602 is fixedly connected to the fixed plate 601, and the other end of the threaded cylinder 602 is connected to the drive rod 603. Accordingly, the drive rod 603 is constructed as a threaded rod and is connected to the drive motor. Sleeve 604 is sleeved on drive rod 603. Sleeve 604 has an outwardly protruding strip platform 607 on its outer periphery. The two ends of transmission rod 605 are rotatably connected to strip platform 607 and transmission plate 606 respectively. One end of transmission plate 606 extends to fixed plate 601 and is connected to pressure rod 502. Correspondingly, fixed plate 601 is provided with matching sliding groove 608. Correspondingly, several pressure rods 502 are provided, and several strip platforms 607, transmission rods 605 and transmission plates 606 are provided respectively to form several transmission groups.

[0031] Based on the above design, the drive motor is started to rotate the drive rod 603. The drive rod 603 rotates along the threaded cylinder 602 and reciprocates linearly relative to the fixed plate 601, moving closer to or away from the fixed plate 601. When the drive rod 603 moves, the sleeve 604, the transmission rod 605, and the transmission plate 606 all move, causing the transmission plate 606 to slide back and forth along the slide groove 608. The pressure rod 502 connected to the transmission plate 606 also reciprocates relative to the slide groove 608, ultimately causing several pressure rods 502 to close or unfold relative to each other, thus forming frame structures of different sizes.

[0032] Furthermore, the transmission plate 606 serves both to connect the pressure rod 502 and to cooperate with the slide groove 608 to limit the movement direction and range of the pressure rod 502. Preferably, as shown in the figure... Figure 3 and Figure 4 As shown, each transmission assembly has two connecting rods. This increases the number of connection points, making the transmission assembly more stable and improving the transmission effect. The pressure plate can also be integrally formed with the base plate of the base 501 to reduce the number of parts and simplify the structure.

[0033] In one possible implementation, the folding module 400 includes a plurality of folding machines 401 forming a frame structure. Each folding machine 401 has a first station housed within the workbench 100 and a second station extending outside the workbench 100. Accordingly, when the folding machine 401 is in the second station, the plurality of folding machines 401 cooperate with each other to fold the packaging cardboard.

[0034] Based on the above design, the folding module 400 is stored at the first station, ensuring it does not obstruct the packaging cardboard during operation, allowing it to flow smoothly on the workbench 100. When idle, it is protected from exposure, reducing the risk of contamination and extending its service life. The second station performs the folding process to complete the packaging cardboard folding operation.

[0035] Specifically, among the multiple folding machines 401, they are arranged in pairs opposite each other and divided into an adjacent first folding group and a second folding group; In the first folding group, the folding machine 401 includes a first substrate 402 that is lifted and disposed on the worktable 100 and a side folding plate 403 located at the end of the first substrate 402. Two side folding plates 403 are provided and are respectively rotatably disposed at both ends of the first substrate 402. In the second folding assembly, the folding machine 401 includes a second substrate 404 that is lifted and disposed on the worktable 100 and a folding plate 405 that is rotatably disposed on the second substrate 404. The upper part of the second substrate 404 is provided with a folding groove 406, and the folding plate 405 is rotatably disposed in the folding groove 406.

[0036] For packaging cardboard, it is divided into a main body in the middle and a folded edge on the outside. The folding operation is to bend the folded edge. Taking two adjacent folded edges of the packaging cardboard as an example, one of them is folded for the first time through the first folding group. That is, after the main body of the packaging cardboard is fixed, the first substrate 402 moves from the first station to the second station. The folded edge is located above the first substrate 402 and is bent when the first substrate 402 moves upward. Then, the end of the bent folded edge is rotated to the other folded edge by the side folding plate 403 to facilitate the connection of the two folded edges. After the end is bent, the side folding plate 403 is reset.

[0037] The second folding is achieved through a second folding assembly. The second substrate 404 moves from the first station to the second station, with the folded edge positioned above the second substrate 404 and bent as the second substrate 404 moves upward. Then, the outer edge of the bent edge is rotated by the folding plate 405 and clamped at the end of the adjacent folded edge to connect the two folded edges. After the two folded edges are connected, the folding plate 405 is reset.

[0038] After the packaging cardboard folding device completes the folding operation, both the first and second folding groups remain in the second working position to resist the packaging cardboard, thereby cooperating with the pressing operation of the pressing module 500 to improve the pressing effect. After the pressing operation is completed, the pressing module 500 resets, and the folding machine 401 moves back to the first working position.

[0039] Preferably, the end of the first substrate 402 is provided with an inner groove, and the side folding plate 403 is slidably disposed on the inner groove by a slider. Correspondingly, the side folding plate 403 has a storage position that is recessed into the inner groove and a folding position that slides out of the inner groove.

[0040] Based on the above design, the inner groove and the slider cooperate to realize the storage of the side folding plate 403, so as to reduce the volume of the folding machine 401, especially the volume when idle, so as to reduce the space occupation. Correspondingly, the slot on the worktable 100 used to accommodate the folding machine 401 can also be smaller.

[0041] In one possible implementation, the workbench 100 is equipped with a pneumatic adsorption mechanism located in the folding area 101, and correspondingly, the workbench 100 has several evenly distributed adsorption holes on its surface. Based on the above design, when the packaging cardboard covers the folding area 101, the pneumatic adsorption mechanism can be activated to fix the position of the packaging cardboard, thereby facilitating subsequent folding and pressing operations.

[0042] As is easily understood, any suitable existing equipment can be used for the pneumatic adsorption mechanism. Furthermore, if the pneumatic adsorption mechanism fails or the fixing effect is poor, the packaging cardboard is pressed down by the pressure module 500 to complete the folding operation.

[0043] In one possible implementation, the conveying module 200 can be either a conveyor belt or a robotic arm. Based on the above design, a conveyor belt is less expensive, but the packaging cardboard will experience some wear during transport. Conversely, a robotic arm is more expensive but will not cause wear on the packaging cardboard. Those skilled in the art can choose according to their needs.

[0044] Optionally, when the conveying module 200 uses a conveyor belt, the conveyor belt includes a first conveying section located upstream of the folding zone 101, a second conveying section located within the folding zone 101, and a third conveying section located downstream of the folding zone 101.

[0045] Optionally, when the conveying module 200 uses a robotic arm, the working end of the robotic arm is constructed as a pneumatic adsorption plate. The adsorption plate is simply a plate with pneumatic adsorption function; any suitable existing model can be selected.

[0046] In one possible implementation, the position detection module 300 includes a detection board 301 and a reset board; Along the direction of packaging paperboard conveying, the detection plate 301 is set on the workbench 100 and located downstream of the folding area 101. Two detection sensors are provided on the outer surface of the detection plate 301 facing the folding area 101, respectively located at both ends of the detection plate 301. Two composite plates 302 are provided and respectively disposed on both sides of the detection plate 301, and the composite plate 302 is located upstream of the detection plate 301; the composite plate 302 has two opposite ends, the end adjacent to the detection plate 301 is configured as the driving end of the worktable 100 for rotational connection, and the end away from the detection plate 301 is configured as a free end. Accordingly, both the detection plate 301 and the composite plate 302 are located outside the folding machine 401; Accordingly, the composite plate 302 has a feeding station where the two composite plates 302 rotate and their free ends move away from each other, and a clamping station where the two composite plates 302 are parallel to each other.

[0047] Based on the above design, the packaging cardboard may experience incomplete feeding, especially when transported via a conveyor belt. Therefore, a positioning detection module 300 is used for detection and correction. Specifically, when the packaging cardboard enters the folding area 101, the composite plate 302 is in the feeding position. The two composite plates 302 form a funnel-shaped structure with a gradually decreasing opening in the packaging cardboard conveying direction to ensure the packaging cardboard can smoothly enter the folding area 101. The composite plate 302 then rotates to the clamping position, so that the end of the packaging cardboard abutting the detection plate 301 is detected by two sensors, indicating that the packaging cardboard is in place, thus proceeding to the next step. If the detection plate 301 malfunctions, the operator is notified immediately for handling.

[0048] As is easily understood, any suitable existing model of detection sensor can be selected. The composite plate 302 is not only used to clamp the packaging cardboard, but also to correct the position of the packaging cardboard when switching from the feeding station to the clamping station, so as to improve the placement rate of the packaging cardboard.

[0049] Optionally, when the conveyor module 200 uses a conveyor belt, the detection plate 301 is telescopically mounted on the workbench 100. Based on the above design, before the folding operation, the detection plate 301 is located on the workbench 100 to block the packaging cardboard. After the operation is completed, the detection plate 301 is retracted into the workbench 100 to avoid obstructing the flow of the packaging cardboard.

[0050] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
