[0002] In the small fresh fruit blister packaging industry, after weighing, the fruit needs to be loaded into the blister box for conveying and capping. Existing technologies typically employ two methods for capping blister boxes: lever capping and cylinder capping. With lever capping, the slightly larger blister box body doesn't easily concentrate stress at the undercut, making it suitable only for small, rigid blister boxes. With cylinder capping, the conveyor stops at a position that doesn't lie directly below the cylinder capping mechanism, and even slightly offset snaps prevent the box from closing. This necessitates multiple cylinders to correct the position, and subsequent processes require manual inspection to remove uncovered boxes.

[0003] However, in the actual production process, sometimes slightly larger packaging boxes are chosen to package small fresh fruits. The slightly larger packaging boxes have snaps, and the traditional box covering method easily causes the snaps to deviate slightly, which makes it impossible to close the lid of the box.

[0027] The present invention will be described in detail below with reference to the accompanying drawings. What is described here is merely a preferred embodiment of the present invention, and those skilled in the art may conceive of other methods for implementing the present invention based on the preferred embodiment, and such other methods also fall within the scope of the present invention.

[0028] Example

[0029] Please refer to Figures 1-6This embodiment provides a fruit box packaging and capping device, comprising a conveying assembly 100 and a capping assembly 200. The conveying assembly 100 conveys the packaging box toward the capping assembly 200. A tilting rod assembly 300 is provided on the conveying assembly 100, which is used to flip the lid of the packaging box to a specified position. The capping assembly 200 includes a power unit 210, an actuator unit 220, and a guide unit 230. The actuator unit 220 and the guide unit 230 are both connected to the power unit 210. The power unit 210 drives the actuator unit 220 to snap the lid of the packaging box, and the guide unit 230 presses the actuator unit 220 against the snap of the packaging box. During the conveying process of the packaging box, the tilting rod assembly 300 flips the lid of the packaging box to a specified position to facilitate the capping by the capping assembly 200. The cover pressing assembly 200 guides and limits the execution unit 220 through the guide unit 230, so that the guide unit 230 can press on the snap button of the packaging box, avoiding deviation between the execution unit 220 and the snap button, so that a slightly larger packaging box with snap buttons can also complete the closing work smoothly.

[0030] It can be understood that the packaging box is generally a blister packaging box, and the conveying component 100 adopts a more common conveying structure, such as a conveyor belt conveyor, a conveyor chain conveyor or a chain plate conveyor. In this embodiment, a chain plate conveyor is mainly used, and the chain plate structure is more stable in carrying the blister packaging box.

[0031] Specifically, in some embodiments of the present application, Figure 2 and Figure 3 As shown, the execution unit 220 includes a plurality of click-button top columns, and the number of the click-button top columns corresponds to the number of snaps. The number of the click-button top columns can be one, two, or even more, which is specifically determined according to the number of snaps in the packaging box. In this embodiment, the number of the click-button top columns is two. The position of the click-button top columns matches the position of the snaps to ensure that the click-button top columns can be accurately pressed onto the snaps. The click-button top columns and the guide unit 230 are both mounted on the pressure plate 240, and the pressure plate 240 is connected to the power unit 210. When the power unit 210 drives the pressure plate 240 to move, the click-button top columns and the guide unit 230 can move together with the pressure plate 240.

[0032] In some embodiments of the present application, Figure 3 As shown, the guide unit 230 includes a pair of guide claws mounted on opposite sides of the pressure plate 240. These claws create a space for the package lid to be closed. This space increases the contact area between the guide claws and the lid, enhancing stability during the closing process and improving the accuracy of contact between the top post and the snap. It is understood that the guide claws are L-shaped with the opening facing downward.

[0033] Further, the guide claw is provided with a wedge surface 231 facing the end surface of the packaging box, and the wedge surface 231 is gradually tapered towards the direction of the pressing cover space. The wedge surface 231 makes the guide claw contact the edge of the packaging box when contacting the packaging box, and can provide a pushing force to the packaging box, so that the position of the packaging box can be finely adjusted, thereby further increasing the accuracy of the butt joint of the point buckle top post and the buckle.

[0034] It can be understood that the point buckle top post and the guide claw are detachably connected with the pressing plate 240. The point buckle top post and the guide claw are connected in this way, which can adjust the distance between the two point buckle top posts, and can adapt to packaging boxes with different spacing buckles. At the same time, the two guide claws can also adjust the spacing to adapt to packaging boxes of different sizes, greatly improving the applicability of the device.

[0035] It should be noted that the power unit 210 can have many kinds of mechanisms, which can provide a pushing force to the position of the packaging box. For example, the power unit 210 can adopt a pneumatic cylinder, a hydraulic cylinder or an electric push rod, and the output end of the pneumatic cylinder, the hydraulic cylinder or the electric push rod is connected with the pressing plate 240. Specifically, the power unit 210 in the embodiment adopts a pneumatic cylinder.

[0036] As shown in some embodiments of the present application, Figure 3 The pressing cover assembly 200 further includes a support frame 270, and a sliding block sliding rail mechanism 260 is installed on the support frame 270. The power unit 210 is connected with the sliding block sliding rail mechanism 260, and the sliding block sliding rail mechanism 260 is arranged vertically to the conveying direction of the conveying assembly 100. The sliding block sliding rail mechanism 260 can move the power unit 210 back and forth in the vertical conveying direction, so as to adjust the positions of the guide claw and the point buckle top post, so that the guide claw and the point buckle top post can more perfectly match the positions of the packaging box and the buckle. It can be understood that the conveying assembly 100 passes through the support frame 270 to convey the packaging box below the support frame 270.

[0037] Further, in some embodiments of the present application, an adjusting device 250 is installed on the support frame 270, the output end of the adjusting device 250 is connected with the power unit 210, and the output direction of the adjusting device 250 is parallel to the conveying direction of the conveying assembly 100. The adjusting device 250 can adjust the position of the power unit 210 in the conveying direction, so as to adjust the positions of the guide claw and the point buckle top post. When facing packaging boxes with large volumes, the packaging boxes are arranged with spacing, and the position of the pressing cover can be changed by the adjusting device 250, so as to facilitate the closing work of the packaging boxes in different positions. It should be noted that the adjusting device 250 adopts an adjusting pneumatic cylinder structure, and the adjusting pneumatic cylinder stroke is simple to change, which can increase the structural stability of the device.

[0038] In order to be able to adjust the packaging box from a fully open state to a closed state, thereby facilitating the subsequent capping work. In some embodiments of the present application, such as Figure 4-Figure 6 As shown, the tilting rod assembly 300 includes a tilting rod segment 310, a pressure rod segment 320, and a plurality of support rods 330. The tilting rod segment 310 and the pressure rod segment 320 are mounted on the conveyor assembly 100 via the support rods 330. One end of the tilting rod segment 310 extends below the lid of the open package box and is close to the edge of the conveying plane of the conveyor assembly 100. The tilting rod segment 310 gradually bends from the edge of the conveying plane toward the center of the conveying plane, gradually increasing its distance from the conveying plane. As the package box is conveyed along the conveyor assembly 100 toward the capping assembly 200, the structure of the tilting rod segment 310 causes the lid of the package box to gradually tilt upward from its open, flat position and be pressed together. At this point, the lid is not completely closed. The pressure bar section 320 is arranged parallel to the conveying plane. A partially closed package is conveyed to the pressure bar section 320. The pressure bar section 320 maintains the partially closed package until the lid is fully closed by the lid pressing assembly 200. The fully closed package is then conveyed from the lid pressing assembly 200 to the next station. Support rods 330 are arranged at intervals along the conveying direction of the conveying assembly 100. The support rods 330 maintain the structural stability of the flip bar section 310 and the pressure bar section 320.

[0039] Furthermore, the support rod 330 is provided with an adjustment member 331. The adjustment member 331 adjusts the height of the tilting rod section 310 and the pressure rod section 320 from the conveying plane of the conveyor assembly 100, thereby accommodating packaging boxes of different depths, thereby achieving the purpose of capping packaging boxes of various specifications. In the embodiment of the present application, the adjustment member 331 is a bolt structure. By adjusting the tightness of the bolt, the tilting rod section 310 and the pressure rod section 320 can be moved up and down along the support rod 330, thereby adjusting the distance between the tilting rod section 310 and the pressure rod section 320 and the conveying plane.
