Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4 This utility model provides a technical solution: a box lid forming machine, including a frame 1, a rotating feeding tray 2, a pre-bending glue-applying base 3, a translational robot 4, a material gripping suction cup 5, a forming transfer suction cup 6, a forming mold 7, a material unloading robot 8, and a blocking assembly 9; the frame 1 is welded from steel pipes and steel plates and is used to fix the workpieces on the equipment; the rotating feeding tray 2 is fixed to the frame 1 by a slewing bearing, driven by a servo motor, and can swing 180 degrees to switch between different material bins, with a lifting cylinder set at the corresponding position at the bottom to ensure that the material is always at a uniform height; the pre-bending glue-applying base 3 is fixed to the frame 1, and the top of the pre-bending glue-applying base 3 is a support. The platform has a side-mounted alignment cylinder and a height-adjustable pre-bending mold at the corresponding folding edges. After the cardboard is in place, it can be pre-folded at a certain angle and glued to facilitate subsequent forming. A translation robot 4 is mounted on the pre-bending and gluing base 3. A material-gripping suction cup 5 is mounted on the rotating feeding tray 2. A forming transfer suction cup 6 is also mounted on the pre-bending and gluing base 3. The forming mold 7 and the unloading robot 8 are both fixed to the top of the frame 1. A conveyor is mounted on the forming mold 7, and a blocking component 9 is mounted on the conveyor. The translation robot 4 consists of a servo motor, synchronous belt, linear guide rail, and slide plate, and suction cup components for different workstations are installed on the slide plate at corresponding positions.

The mold can move up and down along the optical shafts. Four ejection cylinders are set inside the upper mold. The lower mold is a U-shaped structure with guides and is fixed to the frame by bolts. Four folding ear cylinders are set at the four corners of the lower mold. The lower mold has a notch on the side facing the material feeding and is equipped with a conveyor belt. When the forming transfer suction cup 6 puts the cardboard between the upper and lower molds, the cylinder drives the upper mold to press the cardboard into the lower mold. During this process, the folding ear cylinders press the four corners into the lower mold. At this time, the box cover has been formed.

[0019] This invention uses a rotating feeding tray 2 to feed box cover raw materials. A translational robot 4 can transfer box cover cardboard between different workstations. A gripping suction cup 5 picks up the box cover cardboard from the rotating feeding tray 2 and places it on the pre-bending and gluing base 3, pressing it firmly while simultaneously bending it. After bending, the feeding suction cup returns to the feeding position, and the forming transfer suction cup 6 can transfer the cardboard between the pre-bending and gluing base 3 and the forming workstation. After the box cover is formed by the forming mold 7, the forming box cover is pushed down onto the conveyor belt by the ejector cylinder on the mold 7. Then, the unloading robot 8 flips the box cover on the conveyor belt 180 degrees and places it in the unloading area. Compared with the prior art, this invention has a simple and reasonable structure, ingenious design, and can automatically and continuously process box covers with high forming efficiency and good performance.

[0020] In a preferred embodiment, the blocking assembly 9 includes a fixed base 901, a sliding groove 902, a sliding block 903, a moving frame 904, a blocking plate 905, a servo cylinder 906, a transmission plate 907, a limiting groove 908, and a limiting block 909; the fixed base 901 is fixedly connected to the conveyor; the sliding groove 902 is provided on the bottom surface of the fixed base 901; two sliding blocks 903 are symmetrically slidably inserted into the sliding groove 902; the moving frame 904 is fixedly connected to the sliding blocks 903; the blocking plate 905 is fixedly connected to the end of the moving frame 904, and the blocking plate 905 contacts the side of the box cover; the sliding block 903 is larger at the top and larger at the bottom. A small isosceles trapezoidal structure is used to facilitate vertical restriction of the moving frame 904; the moving frame 904 has a U-shaped structure to facilitate avoidance of the conveyor; the servo cylinder 906 is fixedly connected to the conveyor via a cylinder seat; the transmission plate 907 is fixedly connected to the piston end of the servo cylinder 906; a limit groove 908 is provided on the transmission plate 907; two limit blocks 909 are symmetrically slidably inserted into the limit groove 908 and fixedly connected to the moving frame 904; the limit groove 908 has a V-shaped structure, and the tip of the limit groove 908 is positioned close to the servo cylinder 906 to facilitate the movement of the two moving frames 904 relative to or away from each other.

[0021] This invention, by setting a blocking component 9, activates a servo cylinder 906 according to the required lid size, causing the piston rod of the servo cylinder 906 to extend or retract, moving the transmission plate 907, causing the inner wall of the limiting groove 908 to press against the limiting block 909, causing the two limiting blocks 909 to slide relative to or away from each other within the limiting groove 908, causing the two sliding blocks 903 to slide relative to or away from each other within the sliding groove 902, causing the two moving frames 904 to move relative to or away from each other, and causing the two blocking plates 905 to move relative to or away from each other until the blocking plates 905 move to the appropriate position. Then, the servo cylinder 906 is controlled so that the piston rod of the servo cylinder 906 no longer extends or retracts, so as to facilitate correction during the lid conveying process and thus ensure the stability of the lid conveying.

[0022] Working principle: In use, firstly, according to the required box lid size, the servo cylinder 906 is activated, causing the piston rod of the servo cylinder 906 to extend or retract, moving the transmission plate 907. This causes the inner wall of the limiting groove 908 to press against the limiting block 909, causing the two limiting blocks 909 to slide relative to or away from each other within the limiting groove 908. This also causes the two sliding blocks 903 to slide relative to or away from each other within the sliding groove 902, resulting in the two moving frames 904 moving relative to or away from each other, and the two blocking plates 905 moving relative to or away from each other, until the blocking plates 905 move to the appropriate position. Then, the servo cylinder 906 is controlled to stop extending or retracting its piston rod. Then... The box cover material is fed by rotating the feeding tray 2. The translation robot 4 can transfer the box cover cardboard between different workstations. The gripping suction cup 5 picks up the box cover cardboard from the rotating feeding tray 2 and places it on the pre-bending glue base 3 and presses it. At the same time, it cooperates with the bending action. After the bending is completed, the feeding suction cup returns to the feeding position. The forming transfer suction cup 6 can transfer the cardboard between the pre-bending glue base 3 and the forming workstation. After the box cover is processed and shaped by the forming mold 7, the forming box cover is pushed down onto the conveyor belt by the ejector cylinder on the mold 7. Then, the unloading robot 8 flips the box cover on the conveyor belt 180 degrees and puts it into the unloading area.
