[0002] Edge-sealing machines are commonly used in the processing of packaging boxes. They are mainly used to package the sides of packaging boxes by folding the edges. Then, the edges of the packaging box are sealed at the folded edges to complete the subsequent production process.

[0003] There are many types of traditional edge-sealing machines. However, in the process of packaging box production, the processing efficiency is relatively low, and some operations rely on manual labor. A reference can be made to an existing patent (Chinese patent application number CN201921030139.5, application date 2019-07-02) which discloses an edge-sealing mechanism and machine for packaging box components. This includes a rubber wheel, a drive motor connected to the rubber wheel, a rubber box for supplying rubber to the rubber wheel, and a driven wheel that abuts against the rubber wheel. The driven wheel moves synchronously with the rubber wheel when it rotates. The drive motor is connected to the main... The control module is electrically connected, and the frame has an adhesive application button. After the user presses the adhesive application button, the drive motor will drive the adhesive wheel to rotate forward a certain distance and then reverse. The user holds the insert head of the strip and inserts it between the adhesive wheel and the driven wheel. Pressing the adhesive application button, the main control module controls the drive motor to rotate, and the adhesive wheel and the driven wheel move synchronously, winding the insert head between the adhesive wheel and the driven wheel. Then the insert head is retracted, completing the adhesive application of the insert head. The setting of the adhesive application component makes the adhesive application process simple and convenient, avoiding too little or too much adhesive, and facilitating the smooth progress of subsequent steps.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0027] Please see Figures 1-7 The present invention provides the following technical solution: a sealing machine for packaging box production.

[0028] Example 1: To address the issue that current edge-sealing machines on the market require repeatedly removing and repositioning packaging boxes before applying glue, a cumbersome process that hinders rapid production, please refer to the attached... Figure 1 -Appendix Figure 4The inner side of the frame 1 is equipped with two sets of transmission rollers 16 for conveying packaging paper bags. A glue cylinder 14 for dispensing glue is located above the frame 1. A drive unit is installed on one side of the frame 1, providing power to the moving mechanism to move the packaging paper bags between the two sets of transmission rollers 16. The moving mechanism is linked to a one-way rotation mechanism, which drives the limited packaging paper bags to rotate in one direction. The drive unit includes a rotary motor 3, the output end of which is connected to the shaft end of a threaded rod 4 included in the moving mechanism. A threaded connecting block 5 is threadedly connected to the outer side of the threaded rod 4, and the upper end of the threaded connecting block 5 rotates. A connecting rod 10 is connected, and a one-way rotating mechanism is assembled in the middle of the connecting rod 10. A cardboard clamp 11 for clamping the edge of the packaging paper bag is fixed at the top of the connecting rod 10. The inner side of the cardboard clamp 11 is provided with an anti-slip rubber pad, and its clamping gap can be adjusted adaptively by adjusting bolts. The one-way rotating mechanism includes a rotating gear 6 rotatably set in the middle of the connecting rod 10. The outer side of the rotating gear 6 is meshed with a mating rack 7 fixed on the surface of the frame 1. A pawl 8 is rotatably connected inside the rotating gear 6. The outer side of the pawl 8 is engaged with the outer side of the ratchet 9 through a slot. The inner side of the ratchet 9 is fixedly connected to the middle of the connecting rod 10.

[0029] First, the cardboard clamp 11 holds the edge of the packaging paper bag. Its inner anti-slip rubber pad prevents slippage, and the clamping gap can be adjusted with bolts to accommodate different sizes of paper bags, achieving stable positioning. Next, the control panel 2 starts the rotating motor 3, which drives the threaded rod 4 of the moving mechanism to rotate. This causes the threaded connecting block 5, connected by the outer thread, to move along the threaded rod 4. This, in turn, moves the cardboard clamp 11 and the held packaging paper bag via the connecting rod 10, ultimately conveying them between the two sets of transmission rollers 16. When the connecting rod 10 reaches its maximum position, and the packaging paper… After the bag is no longer between the two sets of drive rollers 16, the rotating gear 6 in the middle meshes with the matching rack 7 on the surface of the frame 1, causing the rotating gear 6 to rotate. The pawl 8 inside the rotating gear 6 engages with the ratchet 9 fixed on the connecting rod 10 through a slot. Utilizing the unidirectional transmission characteristics of the pawl 8 and the ratchet 9, the connecting rod 10 and the packaging paper bag are driven to rotate in a unidirectional angle. Through the above process, the packaging paper bag can complete the unidirectional angle adjustment during the conveying process without repeated picking and putting, and directly enters the subsequent processing stage of the drive roller 16, effectively simplifying the operation process and improving production efficiency.

[0030] Example 2: For quick adhesive application, please refer to the attached document. Figure 1 Appendix Figure 2 and attached Figure 5 -Appendix Figure 7The rotating conveying action of the two sets of drive rollers 16 can drive the pressurizing mechanism, which can convey the glue in the glue cylinder 14 to the drive rollers 16, and apply the glue to the surface of the packaging paper bag through the rotation of the drive rollers 16; a movable plate 13 is slidably connected to the top of the frame 1, and an electric push rod 12 is fixed to the rear side of the top of the frame 1. The output end of the electric push rod 12 is fixedly connected to the movable plate 13 to drive it to slide along the top of the frame 1. A drive motor 15 is installed on the back of the movable plate 13. The output end of the drive motor 15 is connected to the shaft end of one of the drive rollers 16. A sector gear 17 is fixed to the outside of the output end of the drive motor 15. The outside of the sector gear 17 is connected to the pressurizing mechanism to provide power; the two sets of drive rollers 16 are distributed in parallel vertically. The ends of the two sets of drive rollers 16 are meshed with each other through two sets of gears, and both sets of drive rollers 16 are rotatably set on the surface of the movable plate 13. A rubber sleeve is fitted, and the surface of the rubber sleeve is evenly distributed with annular grooves for storing glue. The working end of the pressurizing mechanism is connected to the inside of the glue cylinder 14. The glue cylinder 14 is provided with an air vent on the outside. The pressurizing mechanism includes a connecting block 18 that meshes with the outside of the sector gear 17. A piston rod 19 is fixed to the top of the connecting block 18. The outside of the piston rod 19 is sealed and fitted to the inner wall of the fixed cylinder 20. The back of the fixed cylinder 20 is fixed to the surface of the moving plate 13. The top of the fixed cylinder 20 is connected to the inside of the glue cylinder 14 through an air supply pipe 21. The top of the air supply pipe 21 is connected to the inside of the glue cylinder 14. The glue cylinder 14 is provided with a one-way air outlet, and the fixed cylinder 20 is provided with a one-way air inlet. A rubber ring is fitted to the outside of the piston rod 19. The outside of the rubber ring is tightly fitted to the inner wall of the fixed cylinder 20 to ensure airtightness. The bottom of the glue cylinder 14 is provided with a glue outlet corresponding to the upper transmission roller 16. A flow control valve is provided at the glue outlet.

[0031] After the drive motor 15 starts, its output end drives one set of transmission rollers 16 to rotate. Since the ends of the two sets of transmission rollers 16 are meshed with each other through gears and are distributed vertically and horizontally, they will rotate synchronously in opposite directions to convey the packaging paper bags entering between them. At the same time, the sector gear 17 on the outer side of the output end of the drive motor 15 rotates together with it. When the sector gear 17 rotates, it meshes with the connecting block 18 in the pressurizing mechanism, driving the connecting block 18 to move up and down, thereby causing the piston rod 19 on the top of the connecting block 18 to reciprocate within the fixed cylinder 20. Because the rubber ring on the outer side of the piston rod 19 is sealed and fitted to the inner wall of the fixed cylinder 20, and the fixed cylinder 20 is equipped with a one-way air inlet and glue... The cylinder 14 is equipped with a one-way air outlet. When the piston rod 19 moves upward, the fixed cylinder 20 draws in air, and when it moves downward, it forces the air into the glue cylinder 14 through the air supply pipe 21. The air pressure pushes the glue in the glue cylinder 14 to flow out from the bottom glue outlet. The glue output can be adjusted by the flow control valve. The outflowing glue contacts the upper drive roller 16. The rubber sleeve on the outside of the drive roller 16 has evenly distributed annular grooves on its surface, which can store glue. As the drive roller 16 rotates, the glue is evenly coated on the surface of the packaging paper bag it passes over. In addition, the electric push rod 12 can drive the moving plate 13 to slide along the top of the frame 1, driving the drive roller 16 and other components to adjust their positions to adapt to different processing requirements.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
