Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figure 1-5 A gluing device for packaging cartons, comprising an electric conveying frame 9, a mounting frame 3 is installed on the top of the electric conveying frame 9, and a storage box 1 is installed on the top of the mounting frame 3 through a support, and a glue outlet 7 is installed on the output end of the storage box 1, two movable frames 10 are arranged inside the mounting frame 3, and a plurality of limiting rollers 13 are evenly spaced inside the two movable frames 10, and the upper and lower ends of the limiting rollers 13 are respectively connected to the top and bottom ends of the movable frames 10 through a rotating shaft, and a plurality of telescopic rods 12 are fixed at one end of the movable frame 10, and one end of the telescopic rods 12 is connected to the inner wall of the mounting frame 3. The two fixing frames 20 are fixed at the bottom end of the mounting frame 3, and the inner walls of the fixing frames 20 are all installed with rotating rods 11 through bearings, one end of the rotating rods 11 is connected to the inner wall of the mounting frame 3 through a rotating shaft, and the other end of the rotating rods 11 penetrates one end of the fixing frame 20 and is installed with a driven bevel gear 22, the top of the mounting frame 3 is installed with a servo motor 2, and the output end of the servo motor 2 extends to the inside of the mounting frame 3 and is installed with a driving bevel gear 21, the outer wall of the rotating rod 11 at one end of the fixing frame 20 is sleeved with a sliding sleeve 14, and the sliding sleeve 14 is fixed to the top of the movable frame 10;

[0023] Specifically, Figure 1 , Figure 2 and Figure 4As shown, when the device is working, the electric conveyor frame 9 is used to convey and move the carton, so that the carton and the glue nozzle 7 move relative to each other, and the glue nozzle 7 draws the glue inside the storage box 1 and applies it to the upper surface of the carton. The equipment composed of the glue nozzle 7 and the storage box 1 is a common equipment in the prior art, so its specific working principle and internal structure are not repeated here. In order to ensure that the carton can move smoothly and avoid deflection or offset that causes inaccurate coating position, after the carton is placed, the distance between the movable frames 10 can be adjusted so that the two sets of limiting rollers 13 are respectively attached to the two sides of the carton, thereby guiding the movement of the carton.

[0024] One end of the outer wall of the rotating rod 11 is provided with an external thread, and the inner wall of the sliding sleeve 14 is provided with an internal thread matching the external thread;

[0025] The driving bevel gear 21 and the driven bevel gear 22 have the same shape and size, and the driving bevel gear 21 and the driven bevel gear 22 are meshed with each other;

[0026] Two guide columns are fixed between the two ends of the interior of the mounting frame 3, and two guide sleeves are slidably mounted on the outer walls of the guide columns, and the bottom ends of the guide sleeves are fixed to the top of the movable frame 10;

[0027] Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the servo motor 2 is started to drive the active bevel gear 21 to rotate. With the help of the cooperation between the active bevel gear 21 and the driven bevel gear 22, the two driven bevel gears 22 can rotate at the same speed, so that the two rotating rods 11 can rotate at the same speed. The threads on the two rotating rods 11 are exactly the same. At the same time, the sliding sleeve 14 is connected to the movable frame 10. The movable frame 10 is also restricted by the guidance due to the cooperation between the guide column and the guide sleeve and the existence of the telescopic rod 12. Therefore, the sliding sleeve 14 that is threadedly matched with the rotating rod 11 cannot rotate and can only move toward each other on the outer wall of the rotating rod 11, so that the two movable frames 10 can move toward each other at the same speed and adjust the distance between them.

[0028] The outer wall of the glue nozzle 7 is fixed with a mounting block 6, and both ends of the mounting block 6 are fixed with fixing plates 15. A fixing plate 5 is fixed to one side of the storage box 1, and an electric push rod 4 is installed on the top of the fixing plate 5. The output ends of the electric push rod 4 are fixed to the top of the fixing plate 15.

[0029] Both ends of the mounting block 6 are provided with grooves 18, and one end of the groove 18 is installed with a rotating shaft 17 through a rotating shaft, one end of the rotating shaft 17 extends to the outer wall of the mounting block 6 and is installed with a mounting rod 19, and the bottom ends of the two mounting rods 19 extend to the bottom of the mounting block 6, and a mounting roller 8 is installed between one ends of the two mounting rods 19 through a rotating shaft, and a torsion spring 16 is wound around the outer wall of the rotating shaft 17, one end of the torsion spring 16 is fixed to the outer wall of the rotating shaft 17, and the other end of the torsion spring 16 is fixed to the inner wall of the groove 18;

[0030] The connection between the rotating shaft 17 and the groove 18 is a rotational connection, and the rotation range of the rotating shaft 17 is 0°-45°;

[0031] Specifically, Figure 1 and Figure 3 As shown, the position of the mounting block 6 can be changed by the electric push rod 4, thereby changing the distance between the bottom end of the glue nozzle 7 and the carton, and adjusting it as needed. At the same time, the torsion spring 16 can slightly drive the rotating shaft 17 to rotate, causing the mounting rod 19 to swing, so that the mounting roller 8 is gently pressed on the top of the carton. In this way, when the top of the carton is coated with glue, the mounting roller 8 can further spread this part of the glue evenly to avoid uneven thickness.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
