[0038] Please refer to Figures 1 to 6 , a device for flattening the four sides of the top of a packaging box provided in the embodiments of the present application includes a mounting plate 1, a scraping edge mechanism, and a lifting mechanism; the mounting plate 1 is connected to a manipulator 2; a plurality of groups of the scraping edge mechanisms are provided and are arranged at intervals in the same direction on the mounting plate 1. Each group of the scraping edge mechanisms includes a scraping edge roller 31 for contacting the top of the packaging box. In the initial state, the axes of the plurality of scraping edge rollers 31 are horizontal and coaxially arranged; the lifting mechanism is arranged on the mounting plate 1, and the lifting mechanism is connected to some of the scraping edge mechanisms to drive the corresponding scraping edge rollers 31 to lift upward by a certain height.

[0039] In this embodiment, the mounting plate 1 not only serves as a connecting member to the manipulator 2 but also as a mounting carrier for the edge scraping mechanism and the lifting mechanism. During use, multiple packaging boxes are placed side by side. The manipulator 2 drives the mounting plate 1 to translate, causing multiple edge scraping rollers 31 to move synchronously along one edge direction of the packaging box, thereby flattening multiple edges of the packaging box in this direction. Then, the manipulator 2 drives the mounting plate 1 to horizontally rotate 90°. At this time, the corresponding edge scraping rollers 31 are driven by the lifting mechanism to lift upward by a certain height, and only two edge scraping rollers 31 need to work. The manipulator drives the two edge scraping rollers 31 to move along another edge direction of the packaging box, successively flattening two edges of the multiple packaging boxes in this direction.

[0040] The flexible movement range and steering of the manipulator 2 in this device ensure the diversity of applicable environments; by controlling the lifting of some edge scraping rollers 31 through the lifting mechanism, the edge scraping rollers 31 can be used or shielded according to the needs of the packaging box; this device can replace manual edge scraping, saving human resources, ensuring the edge scraping effect and not easily damaging the paper box, and can directly meet the four edges of the paper box.

[0041] According to some embodiments of the present application, each set of the edge scraping mechanism further includes a mounting seat 32 and a guide rod 33. The mounting seat 32 is fixedly arranged on the mounting plate 1 by bolts. The guide rod 33 is arranged vertically on the mounting seat 32. The edge scraping roller 31 is arranged at the lower end of the guide rod 33, and the lifting mechanism is connected to the upper end of the guide rod 33.

[0042] The mounting seat 32 in this embodiment has a rectangular block structure with a rectangular hollow cavity in the center. One side of the mounting seat 32 is attached to the mounting plate 1 and is fixedly connected to the mounting plate 1 by four bolts. The other side of the mounting seat 32 is covered with a cover plate 39, and the cover plate 39 is connected to the mounting seat 32 by screws at the four corners to close the entrance of the hollow cavity.

[0043] According to some embodiments of the present application, the upper part of the guide rod 33 is a square rod section, and the lower part is a round rod section; the mounting seat 32 is provided with a square guide sleeve 34 and a round guide sleeve 35 adapted to the square rod section and the round rod section. The radial dimension of the square rod section is slightly larger than that of the round rod section. The square rod section and the round rod section can be machined by cutting a whole rod, or can also be formed by splicing two sections together.

[0044] Specifically, a square guide sleeve 34 is inlaid on the upper part of the mounting base 32, and its lower end extends into the hollow cavity of the mounting base 32. The square guide sleeve 34 has a through hole inside that is adapted to the cross-section of the square rod section. A circular guide sleeve 35 is inlaid on the lower part of the mounting base 32, and its upper end extends into the hollow cavity of the mounting base 32. The circular guide sleeve 35 has a through hole inside that is adapted to the cross-section of the round rod section. Since the guide rod 33 is in the form of a combination of a square rod section and a round rod section, the guide rod 33 will not rotate around its own axis while sliding up and down vertically.

[0045] According to some embodiments of the present application, a compression spring 36 is arranged in the mounting base 32. The compression spring 36 is sleeved on the guide rod 33, and the guide rod 33 is mounted on the mounting base 32 through the compression spring 36 so as to be able to float up and down. The compression spring 36 is located in the hollow cavity of the mounting base 32. The above structure can enable the scraping edge roller 31 to automatically float up and down when contacting the packaging box. The scraping edge roller 31 controls the scraping pressure through the compression spring 36, so that the scraping force of each scraping edge roller 31 is consistent.

[0046] According to some embodiments of the present application, the compression spring 36 is sleeved on the round rod section of the guide rod 33, and a limit ring 37 is fixedly connected to the round rod section through a screw; the upper end of the compression spring 36 abuts against the lower end surface of the square guide sleeve 34, and the lower end of the compression spring 36 abuts against the upper end surface of the limit ring 37.

[0047] In the initial state, under the action of the compression spring 36, the lower end surface of the limit ring 37 abuts against the upper end surface of the circular guide sleeve 35; when the scraping edge roller 31 contacts the top of the packaging box, it will push the guide rod 33 to move upward, which will cause the compression spring 36 to be compressed; since the limit ring 37 moves up and down synchronously with the guide rod 33, the change in the height of the limit ring 37 will cause the compression amplitude of the compression spring 36 to change correspondingly.

[0048] According to some embodiments of the present application, the lower end of the guide rod 33 is fixedly connected with a roller seat 38 through a bolt, and the scraping edge roller 31 is rotatably mounted on the roller seat 38. Specifically, the roller seat 38 is generally in a U-shaped structure and can be formed by splicing multiple blocks or can be directly machined from a whole piece of material. The scraping edge roller 31 is located inside the U-shaped opening of the roller seat 38. The scraping edge roller 31 is rotatably connected to the roller seat 38 through a rotating shaft. When leveling the packaging box, the scraping edge roller 31 can rotate relative to the roller seat 38, so that the scraping edge roller 31 can roll along the edge of the packaging box.

[0049] According to some embodiments of the present application, the lifting mechanism includes a lifting cylinder 4 and a connecting plate 5. The lifting cylinder 4 is fixedly arranged on the mounting plate 1. The output end of the lifting cylinder 4 is connected to the connecting plate 5, and the connecting plate 5 is connected to a guide rod 33 in part of the edge scraping mechanism. The lifting cylinder 4 is fixed to the mounting plate 1 by screws and is located on different sides of the mounting plate 1 from the mounting seat 32, that is, the lifting cylinder 4 and the mounting seat 32 are respectively located on both sides of the mounting plate 1. The connecting plate 5 is not only connected to the piston rod of the lifting cylinder 4 but also connected to the guide rod 33 in part of the edge scraping mechanism. Through the telescopic movement of the piston rod of the lifting cylinder 4, the connecting plate 5 can be driven to move up and down vertically, thereby driving the connected guide rod 33 to move up and down vertically.

[0050] According to some embodiments of the present application, four groups of edge scraping mechanisms are provided, and the lifting mechanism is connected to the two middle groups of edge scraping mechanisms. Specifically, the connecting plate 5 is U-shaped. The middle of the connecting plate 5 is connected to the piston rod of the lifting cylinder 4, and the two ends of the connecting plate 5 are connected to the upper ends of two guide rods 33 in the two middle groups of edge scraping mechanisms.

[0051] According to some embodiments of the present application, the mounting plate 1 is arranged vertically, and a connecting sleeve 11 for connecting to the manipulator 2 is provided at its top end. The mounting plate 1 can be machined by cutting a whole board or can be spliced by multiple board pieces; the connecting sleeve 11 is circular. The center of the connecting sleeve 11 has a through hole adapted to the rod body at the front end of the manipulator 2. A slit is axially opened on the circumference of the connecting sleeve 11. By pulling the two sides of the slit with screws, the aperture of the through hole in the center of the connecting sleeve 11 can be made smaller, so as to lock it on the rod body of the manipulator.

[0052] By providing the connecting sleeve 11, the rod body at the front end of the manipulator 2 extends into the connecting sleeve 11, and the connecting sleeve 11 is locked on the rod body at the front end of the manipulator 2 by screws. The manipulator 2 drives the whole device to move for edge scraping. Since the manipulator can move and turn flexibly, it ensures the diversity of the applicable environments of the device.

[0053] Taking four groups of edge scraping mechanisms as an example, the working process of the device is described as follows: ① The packaging box is a square box. Each packaging box has two long edges and two short edges. After two packaging boxes are conveyed side by side to the working station via the belt line, the manipulator 2 drives the device to press the four edge scraping rollers 31 against the long edges of the packaging box respectively, and scrape from one end of the long edge to the other end of the long edge to flatten the long edges of the packaging box; ② The manipulator 2 lifts the device and turns it 90°. At this time, the lifting cylinder 4 lifts the two middle edge scraping rollers 31 upward by a certain height. Then the manipulator 2 drives the edge scraping rollers 31 on both sides of the device to press against the short edges of the packaging box (two packaging boxes side by side), and scrape from one side of the short edge to the other side of the short edge to flatten the short edges of the packaging box. Compression springs 36 are installed on the four edge scraping rollers 31 in the device to ensure balanced force on each edge; the lifting cylinder 4 can lift the two middle edge scraping rollers 31 of the device to prevent the long edges from being damaged when flattening the short edges of the packaging box.

[0054] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above description is only the specific embodiments of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
