Workers first bend the partitions into their desired shapes and then insert them into the boxes according to their positions. This process is inefficient, and manual operation can easily lead to problems such as incomplete bending and misalignment of the partitions. Therefore, there is an urgent need for equipment that can automatically pack the partitions. Summary of the Invention

[0029] Reference Figure 1 According to a first aspect of the present invention, a partitioned box packing machine includes a conveying device 100, a shaping assembly 200, a feeding assembly 300, and a transfer mechanism 400. The conveying device 100 is mainly used for conveying and feeding / unloading packaging boxes and can be a belt conveyor, roller conveyor, etc. The shaping assembly 200 is located above the conveying device 100 and includes two shaping plates 210 spaced apart in a horizontal direction. In practical applications, the entire shaping assembly 200 is mounted on a frame, which provides a fixed mounting position for the shaping assembly 200. At this time, the two shaping plates... Plate 210 is connected to the frame and positioned above the conveying device 100; the feeding assembly 300 is provided with a feeding area; the transfer mechanism 400 has a movable end that can move back and forth between the feeding area, the two shaping plates 210, and the conveying device 100. The movable end is connected to a rotating device 410, which is connected to a transfer device. The rotating device 410 can drive the transfer device to rotate around an axis in the vertical direction. In practical applications, the rotating device 410 is mainly used to provide the driving force for rotation around the axis in the vertical direction, and can be driven by a rotary cylinder or a motor.

[0030] As described above, the conveying device 100 is used to convey packaging boxes that need to be fitted with partitions. The loading area of ​​the loading assembly 300 contains partitions that need to be fitted with packaging boxes. The partitions have creases at the folded edges. During operation, the conveying device 100 transports the packaging boxes to the transfer mechanism 400. The movable end of the transfer mechanism 400 moves the transferor to the loading area. The transferor then transfers the partitions in the loading area between the two shaping plates 210. Then, the rotating device 410 drives the transferor to move to the loading area. The device rotates, causing the two ends of the partition to abut against the two shaping plates 210. The two shaping plates 210 block and limit the two ends of the partition to be folded along the crease, thus folding the partition. Then, the conveyor moves the partition down into the packaging box, completing the partition packing operation. Finally, the conveying device 100 removes the packaging box containing the partition. This can realize automatic partition packing, reduce the operation error when manually packing the partition into the packaging box, and effectively improve the efficiency and quality of partition packing.

[0031] Naturally, the transfer mechanism 400 has a drive source that can drive the transferor to move back and forth in the loading area, between the two shaping plates 210, and between the conveying device 100. For example, the transfer mechanism 400 includes a robotic arm, with the execution end of the robotic arm serving as the movable end. The transferor is connected to the execution end of the robotic arm, and the robotic arm drives the transferor to move between the loading area, between the two shaping plates 210, and between the conveying device 100. In this embodiment, the transfer mechanism 400 includes a transverse drive, a longitudinal drive, and a lifting drive. The transverse drive is connected to the frame, and the longitudinal drive is disposed on the transverse drive. The transverse drive can drive the longitudinal drive to move horizontally. The lifting drive is disposed on the longitudinal drive, and the longitudinal drive drives the lifting drive to move horizontally. The transferor is disposed on the lifting drive, and the lifting end of the lifting drive serves as the movable end. The lifting drive can drive the transferor to move up and down. During operation, the transverse drive, longitudinal drive and lifting drive provide driving force for movement in the horizontal, vertical and vertical directions, respectively, driving the transferor to move in three dimensions, thereby enabling the transferor to move to the loading area, between the two shaping plates 210 and the conveying device 100.

[0032] In practical applications, the transverse drive, longitudinal drive, and lifting drive are used to provide the driving force for reciprocating motion in a straight line, and can be cylinders, electric lead screws, or hydraulic cylinders, etc.

[0033] The transferor can be used by clamping the partition, and in this embodiment, such as Figure 2 As shown, the method of suctioning the partition is adopted. Specifically, the transfer device includes a rotating rod 411, a transfer plate 420 and a transfer suction cup 430. The rotating device 410 is connected to the rotating rod 411 in a driving manner. The transfer plate 420 is connected to the bottom of the rotating rod 411. Multiple transfer suction cups 430 are connected to the transfer plate 420. During operation, multiple transfer suction cups 430 provide negative pressure suction to remove the partition in the loading area. Then, the rotating device 410 drives the transfer plate 420 to rotate via the rotating rod 411, causing the partition to rotate between the two shaping plates 210 for bending and shaping. Specifically, after the multiple transfer suction cups 430 suck the partition out of the loading plate, it moves above the two shaping plates 210. At this time, the rotating device 410 can drive the partition to rotate to an inclined state with the two shaping plates 210. Then, the partition is moved down between the two shaping plates 210. Next, the rotating device 410 drives the partition to rotate again, so that the two ends of the partition are bent and shaped along the two shaping plates 210.

[0034] To improve stability when the partition is rotated to abut against the two shaping plates 210 and bent into shape, in this embodiment, the transferor further includes a limiting drive member 440 and a limiting plate 450. The limiting drive member 440 is connected to the rotating rod 411 at the position above the transfer plate 420. The limiting drive member 440 is kinetically connected to the limiting plate 450. The limiting drive member 440 can drive the limiting plate 450 to move down to the side of the transfer plate 420 where the transfer suction cup 430 is provided or to move up away from the transfer plate 420. When the transfer plate 420 moves to the loading area, the limiting drive 440 drives the limiting plate 450 to move upward away from the transfer plate 420. At this time, the limiting plate 450 will not block the transfer suction cup 430, and the transfer suction cup 430 can be used to absorb and transfer the partition. Then the limiting drive 440 drives the limiting plate 450 to move downward and get closer to the side of the transfer plate 420. When the partition rotates, the limiting plate 450 can be directly disengaged from the transfer suction cup 430 to better stabilize the partition on the transfer suction cup 430, thereby ensuring the stability of the folded edge forming of the two ends of the partition.

[0035] In practical applications, the partition is flat in the feeding area. However, when the partition is loaded, one end of the partition needs to be bent to one side and the other end needs to be bent to the other side. In order to improve the shaping effect of the partition after folding and shaping when it is loaded into the packaging box, in this embodiment, the transfer plate 420 is connected to a first pressing drive 421, the first pressing drive 421 is driven to a first pressing block 422, the limiting plate 450 is connected to a second pressing drive 451, and the second pressing drive 451 is driven to a second pressing block 452. Taking the direction of adsorption by the transfer suction cup 430 as the first direction and the direction perpendicular to the first direction as the second direction, the first pressing drive 421 can drive the first pressing block 422 to move along the second direction, and the second pressing drive 451 can drive the second pressing block 452 to move along the second direction. The movement directions of the first pressing block 422 and the second pressing block 452 are opposite. When the partition moves down into the packaging box, the first pressing drive 421 and the second pressing drive 451 respectively drive the first pressing block 422 and the second pressing block 452 to approach the transfer plate 420 and the limiting plate 450, so that the first pressing block 422 and the second pressing block 452 avoid the inner wall of the packaging box. After the partition is loaded into the packaging box, the first pressing drive 421 drives the first pressing block 422 to press one end of the partition against the inner wall of the packaging box, and the second pressing drive 451 drives the second pressing block 452 to press the other end of the partition against the inner wall of the packaging box, thereby further pressing and shaping the folded edge of the partition inside the packaging box, improving the effect of the partition loading.

[0036] In practical applications, the first pressing drive 421 and the second pressing drive 451 are mainly used to provide the driving force for reciprocating movement in a straight direction. They have various structural forms, such as cylinders, electric lead screws, or hydraulic cylinders. Multiple first pressing drive 421s can be arranged on the transfer plate 420 in the vertical direction, each driving a first pressing block 422, thereby increasing the force coverage area for pressing the folded edge against the inner wall of the packaging box. Similarly, multiple second pressing drive 451s can also be arranged on the limiting plate 450 in the vertical direction, each driving a second pressing block 452, which also increases the force coverage area for pressing the folded edge against the inner wall of the packaging box.

[0037] To better position the partition inside the packaging box, in this embodiment, as follows: Figure 3 As shown, the shaping assembly 200 also includes a glue gun 220 disposed below the two shaping plates 210. When the two ends of the partition rotate and are folded by the two shaping plates 210, the partition moves downwards. At this time, the glue gun 220 below the shaping plates 210 sprays glue onto the folded edges of the partition. When the partition is fully inserted into the packaging box, the outward restoring force of the folded edges causes them to abut against the inner wall of the packaging box, thereby using glue to firmly adhere the folded edges to the inner wall of the packaging box, thus positioning the partition inside the packaging box. In practical applications, when the first pressing block 422 and the second pressing block 452 press the two folded edges against the inner wall of the packaging box, the adhesion effect between the folded edges and the inner wall of the packaging box can be improved.

[0038] In some embodiments, one end of one of the shaping plates 210 is bent away from the other shaping plate 210, and the two shaping plates 210 are arranged centrally symmetrically. When the partition is rotated, the two ends of the partition are first pressed against the bent portions of the two shaping sections. The bent portions of the shaping plates 210 can guide the partition and improve the smoothness of the partition bending.

[0039] The feeding assembly 300 has a feeding area where partitions can be placed, such as... Figure 4As shown, specifically, the feeding assembly 300 includes a feeding rack 310, an upper baffle 320, and a pusher seat 330. The feeding rack 310 extends downward at an angle close to the transferor. The pusher seat 330 is slidably connected to the feeding rack 310 and can slide along the extending direction of the feeding rack 310. The upper baffle 320 is disposed above the end of the feeding rack 310 near the transferor. An upper baffle 321 is provided on the bottom side of the upper baffle 320, and a lower baffle 311 is provided on the top side of the end of the feeding rack 310 near the transferor. The feeding area is formed between the upper baffle 321 and the lower baffle 311. In practical applications, there can be multiple upper baffles 321 and multiple lower baffles 311, thereby improving the limiting effect on the partition. Multiple partitions are placed on the loading rack 310 and arranged downwards at an angle along the loading rack 310. The weight of the pusher seat 330 is used to press the stacked partitions onto the loading area. The upper baffle 321 and the lower baffle 311 limit the partitions to prevent them from falling directly out of the loading rack 310. When the transfer device needs to pick up a partition, it picks up the partition closest to the loading area and pulls it out of the loading area, so that the top and bottom edges of the partition pass over the upper baffle 321 and the lower baffle 311 respectively, thereby removing the outermost partition.

[0040] To improve the positional accuracy of the packaging boxes during transport on the conveyor device 100, such as Figure 5 As shown, in this embodiment, a guide plate 110 is provided on the top side of the conveying device 100, and two guide plates 110 are spaced apart along the conveying direction perpendicular to the conveying device 100. When the packaging box is conveyed on the conveying device 100, the two guide plates 110 respectively limit the position of the packaging box on both sides, thereby improving the positional accuracy of the packaging box along the width direction of the conveying device 100 when it is moved on the conveying device 100. In practical applications, the ends of the two guide plates 110 near the upstream of the conveying device 100 are bent in a direction away from each other, thereby forming a flared opening, which facilitates the feeding of the packaging box between the two guide plates 110.

[0041] Furthermore, a stop drive component 121 is provided downstream of the conveying device 100. The stop drive component 121 is located above the conveying surface of the conveying device 100 and is connected to a stop block 122. The stop drive component 121 can drive the stop block 122 to move closer to or away from the centerline of the conveying device 100. The stop drive component 121 can be a cylinder, electric screw, or hydraulic cylinder, etc. When the packaging box is conveyed on the conveying device 100, the stop drive component 121 drives the stop block 122 to move along the direction close to the centerline of the conveying device 100. When the packaging box is in position, it is blocked and limited by the stop block 122, thereby restricting its continued conveying and improving the accuracy of the packaging box's positioning along the conveying direction of the conveying device 100. In practical applications, stop drive components 121 are provided on both sides of the conveying surface of the conveying device 100, providing blocking and limiting on both sides of the packaging box.

[0042] To better separate two packaging boxes along the conveying direction, in this embodiment, a blocking drive 131 is provided upstream of the conveying device 100. The blocking drive 131 is located below the conveying surface of the conveying device 100 and is driven by a baffle 132. The blocking drive 131 can drive the baffle 132 to extend upward or downward away from the conveying surface. The blocking drive 131 can be a cylinder, an electric lead screw, or a hydraulic cylinder, etc. When multiple packaging boxes are conveyed simultaneously on the conveying device 100, after the packaging box that needs to be fitted with a partition passes the baffle 132, the blocking drive 131 drives the baffle 132 to extend upward out of the conveying surface, blocking and limiting the next packaging box, thereby improving the accuracy of partitioned box loading.
