[0028] like Figure 1-Figure 2 As shown, this is a high-speed continuous box sealing mechanism, which includes two sets of inner and outer box sealing devices, each of which includes a fixed main board. The two fixed main boards 1 of the two sets of box sealing devices are symmetrically mounted on the frame boards on both sides of the box feeding conveyor of the cartoning machine. A servo motor 2 is installed below one end of the fixed main board 1, and a mounting frame 3 is installed on the other end of the fixed main board. A box sealing turntable 4 is installed on the driving shaft of the servo motor 2 and the mounting frame 3, and a box sealing plate 5 is installed between the two box sealing turntables 4. The two ends of the box sealing plate 5 are respectively connected to the two box sealing turntables 4 for rotation, and the side of the box sealing plate 5 close to the cartoning machine conveyor belt is sequentially mounted with an indentation block 6 and a box sealing block 7.

[0029] In this embodiment, the lower part of one end of the fixed mainboard 1 on which the servo motor 2 is mounted is an inclined structure, and the servo motor 2 is mounted on the fixed mainboard 1 at an angle.

[0030] The mounting frame 3 includes a vertical plate 3-1 vertically mounted on the right end of the fixed mainboard, and a mounting plate 3-2 obliquely mounted on the vertical plate 3-1 and parallel to the inclined surface structure of the fixed mainboard 1. A bearing seat 8 is mounted on the mounting plate 3-2, and a transmission shaft 9 for assembling the box sealing turntable 4 is mounted on the bearing seat 8, and the transmission shaft 9 is parallel to the driving shaft of the servo motor 2.

[0031] The box sealing turntable 4 includes a connecting sleeve 4-1 and a connecting arm 4-2. The left end connecting sleeve is installed on the driving shaft of the servo motor 2, and the right end connecting sleeve is installed on the transmission shaft 9 of the right side mounting frame 3. The upper end surface of the left end connecting sleeve is located at a height lower than the height of the lower end surface of the connecting sleeve installed on the right end transmission shaft 9, and the connecting sleeves 4-1 are parallel to each other; the connecting arm 4-2 is arranged on the outer peripheral wall of the connecting sleeve 4-1, and the two ends of the box sealing plate 5 are rotatably connected with the connecting arms 4-2 on the two connecting sleeves 4-1 through shaft pins.

[0032] There are three connecting arms 4-2 on the connecting sleeve 4-1, and the three connecting arms 4-2 are evenly spaced along the circumferential direction at the end of the connecting sleeve 4-1; there are three box sealing plates 5 between the two box sealing turntables 4, and each box sealing plate 5 is respectively installed between two connecting arms 4-2 parallel to each other on the two connecting sleeves 4-1.

[0033] The present invention adopts inclined surface design and assembly between the fixed main board 1 and the servo motor 2, so that a certain space difference is formed between the two box sealing turntables 4, ensuring that the three box sealing plates 5 are staggered and orderly when rotating to seal the boxes, and do not interfere with each other, driving the indentation block 6 and the box sealing block 7 to seal the boxes in sequence and in an orderly manner for cyclic operation; at the same time, the main body of the box sealing plate 5 is horizontal, and its two ends are designed with oblique angles respectively parallel to the two connecting arms 4-2. When working, the main plane of the box sealing plate 5 always remains horizontal and parallel to the plane of the sealed paper box 11, so that the indentation of the paper box is smooth and the appearance of the sealed box is good.

[0034] The high-speed continuous box sealing mechanism is installed on the box feeding and conveying device of the cartoning machine. The inner and outer sets are symmetrically distributed and driven by the servo motor 2. They run synchronously with the cartoning machine. The inner servo motor 2 drives the box sealing turntable 4 to rotate counterclockwise, and the outer servo motor 2 drives the box sealing turntable 4 to rotate clockwise, thereby driving the indentation block 6 and the box sealing block 7 on the box sealing plate to move in an orderly and staggered manner, and continuously and stably complete the box sealing action at high speed. The above actions are repeated in a cycle to complete the box sealing work; at the same time, the servo motor 2 has a long service life and precise operation control, and runs synchronously with the box feeding and conveying device of the cartoning machine to ensure smooth box sealing.

[0035] In addition, the indentation block 6 and the box sealing block 7 are connected to the box sealing plate 5 by bolts 10 and can be quickly disassembled; when changing the specifications of the paper box, the matching indentation block 6 and box sealing block 7 can be disassembled and replaced, and the operation is convenient and fast, thereby meeting the production needs of products of various specifications.

[0036] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
