[0002] In the production and manufacturing field of packaging boxes, in order to improve the appearance and enhance the waterproof performance of the packaging boxes, a process of wrapping a layer of outer wrapping paper on the outside of the paper box is often adopted. In actual mass production operation process, the common operation mode is to set two conveying belts for conveying the paper box and the outer wrapping paper respectively. The outer wrapping paper is coated with glue on the conveying belt for conveying the outer wrapping paper. When the outer wrapping paper is conveyed to a specific designated position, a mechanical hand is used to grab and place the paper box on the outer wrapping paper coated with glue. Since the outer wrapping paper has been coated with glue at this time, the bottom surface of the paper box will be bonded with the outer wrapping paper. Then, the mechanical hand is used again to grab the paper box with the outer wrapping paper, so that the paper box with the outer wrapping paper enters a folding forming mechanism, and the outer wrapping paper is completely wrapped on the outside of the paper box through the operation of the mechanism, thereby completing the packaging process of the whole packaging box.
[0003] However, the production process in the prior art has obvious defects. Since the glue on the outer wrapping paper is coated for a short time, the adhesion has not fully played a role, and the bonding effect between the paper box and the outer wrapping paper is very poor. In the process of grabbing the paper box by the mechanical hand, due to the insufficient bonding strength, the outer wrapping paper is easily dropped from the paper box. This phenomenon not only causes the interruption of the current production process, but also reduces the production efficiency, increases the waste of raw materials, and may require additional manpower and material resources to maintain and correct the production process due to frequent failures, which brings many adverse effects to the normal production of the packaging box. Therefore, the packaging box glue coating, shaping and pressing mechanism is proposed to solve the above problems. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION
[0031] Please refer to Figs. 1 to 3 , a packaging box gluing and shaping pressing mechanism in the embodiment, comprising a machine base 1, a conveying belt 2 rotatably installed in the machine base 1 and a controller 3 fixedly installed outside the machine base 1, the upper surface of the machine base 1 is provided with an extrusion mechanism 4 extending to the upper surface of the conveying belt 2, the upper surface of the machine base 1 is provided with a reset assembly 5, the extrusion mechanism 4 comprises a mounting frame 41 fixedly connected to the upper surface of the machine base 1, a fixed frame 42 provided on the lower surface of the mounting frame 41, a pressing roller 43 rotatably installed in the fixed frame 42 and a driving mechanism provided on the lower surface of the mounting frame 41;
[0032] The mounting frame 41 and the fixed frame 42 are both in the shape of a Chinese character 'fang', the outer diameter of the fixed frame 42 is matched with the inner diameter of the mounting frame 41, and the compression roller 43 is in abutment with the upper surface of the conveying belt 2.
[0033] Specifically, the driving mechanism includes a moving rod 44 slidingly connected to the inside of the mounting frame 41, a driving motor 45 fixedly installed on the top wall inside the mounting frame 41, a toothed plate 47 fixedly connected to the outside of the moving rod 44, and an incomplete gear 46 fixedly connected to the output shaft of the driving motor 45. Through the cooperation of the controller 2 and the driving motor 45, the automation of the entire compression process is realized, greatly improving the production efficiency. Compared with manual operation, this way is faster and more accurate, reducing errors caused by human factors; the meshing of the incomplete gear 46 and the toothed plate 47 enables the moving rod 44 to move up and down intermittently, and this intermittent movement helps to better control the compression force of the compression roller 43 on the carton and the outer packaging paper, thereby improving the compression effect and ensuring the stability and aesthetics of the packaging box; the up-and-down reciprocating frequency and stroke of the compression roller 43 can be easily adjusted, which means it can adapt to packaging boxes of different sizes. This flexibility enables the same equipment to handle packaging boxes of multiple specifications, reducing production costs and improving equipment utilization. At the same time, since the entire compression process is achieved through mechanical transmission, this design is more simple and convenient to maintain compared to other complex compression methods. Once a fault occurs, it can be quickly located and repaired, reducing downtime and improving equipment reliability. This design achieves efficient compression function through a compact mechanical structure without occupying a large amount of space. This is particularly important for production environments with limited space, as it maximizes the use of existing space and improves production efficiency.
[0034] It should be noted that the moving rod 44 is slidingly connected to the upper surface of the mounting frame 41 and extends to the lower surface thereof, the fixed frame 42 is fixedly connected to the bottom end of the moving rod 44, the driving motor 45 is electrically connected to the controller 3, and the incomplete gear 46 is meshingly connected to the toothed plate 47.
[0035] In addition, the inside of the mounting frame 41 is fixedly installed with a sliding seat 48 matched with the moving rod 44, and the moving rod 44 is slidingly connected to the inside of the sliding seat 48.
[0036] Please refer to Fig. 1 and Fig. 2In this embodiment, the reset assembly 5 includes a guide rod 51 fixedly connected to the top of the fixed frame 42 and a reset spring 52 fixedly connected between the mounting frame 41 and the fixed frame 42. Since the reset spring 52 has elastic deformation characteristics, it can provide stable restoring force when the moving rod 44 reciprocates up and down, ensuring that the moving rod 44 does not shake or deviate during movement. The guide rod 51 serves to accurately guide the movement direction, ensuring that the moving rod 44 moves according to the predetermined trajectory. The combination of the two greatly improves the stability of the moving rod 44 during movement, thereby ensuring uniform extrusion of the carton by the compression roller 43. At the same time, due to the stable movement of the moving rod 44, the compression roller 43 can uniformly extrude the carton, which helps the glue to be evenly distributed between the carton and the outer packaging paper. Uniform glue distribution not only improves the pasting effect of the carton, but also enables the glue to form a more solid adhesive layer after solidification, enhancing the stability and durability of the carton.
[0037] Among them, the guide rod 51 is slidingly connected to the inside of the mounting frame 41, and the reset spring 52 is connected around the outside of the guide rod 51.
[0038] Please refer to Fig. 1 In this embodiment, the machine base 1 is provided with a limiting mechanism 6 extending to the upper surface of the conveyor belt 2. The limiting mechanism 6 includes an electric push rod 61 fixedly installed on the outside of the machine base 1, a limiting plate 62 fixedly connected to the output end of the electric push rod 61, and a limiting rod 63 fixedly connected to the back of the limiting plate 62. The extension distance of the electric push rod 61 can be accurately controlled by the controller 3, ensuring the limiting precision of the limiting plate 62 on the packaging box. This precise limiting control helps to maintain the stability of the packaging box during compression, avoiding displacement or deformation, thereby improving the compression effect and product quality. Since the movement of the limiting plate 62 can adapt to packaging boxes of different sizes, and the pushing force of the electric push rod 61 can be adjusted as needed, this design is also suitable for compression of paper boxes of different materials. Whether it is hardboard, corrugated board or other types of packaging materials, effective limiting can be achieved by adjusting the position of the limiting plate 62 and the pushing force. The extension of the electric push rod 61 can be easily controlled by the controller 3, making the movement of the limiting plate 62 simple and fast. This automated operation reduces manual intervention, improves production efficiency, and also reduces operation difficulty and labor intensity.
[0039] Among them, the number of electric push rods 61 and limiting plates 62 is two, and the two limiting plates 62 are in abutment with the upper surface of the conveyor belt 2. The limiting rod 63 is slidingly connected to the inside of the machine base 1.
[0040] The working principle of the above embodiment is as follows:
[0041] In use, the carton is first intermittently conveyed by the conveyor belt 2, and the extension distance of the electric push rod 61 is accurately controlled by the controller 3, which can ensure the positioning accuracy of the limiting plate 62 on the packaging box. This precise limiting control helps to maintain the stability of the packaging box during the pressing process, avoiding displacement or deformation, thereby improving the pressing effect and product quality. Since the movement of the limiting plate 62 can adapt to packaging boxes of different sizes, and the pushing force of the electric push rod 61 can be adjusted as needed, this design is also suitable for pressing different materials of cartons. Whether it is hardboard, corrugated board or other types of packaging materials, effective limiting can be achieved by adjusting the position of the limiting plate 62 and the pushing force. The extension of the electric push rod 61 can be easily controlled by the controller 3, making the movement of the limiting plate 62 simple and fast. This automated operation reduces manual intervention, improves production efficiency, and also reduces the difficulty and intensity of operation, making it suitable for pressing cartons of different sizes and materials; then the controller 3 starts the drive motor 45 to work and drives the incomplete gear 46 to rotate, the incomplete gear 46 rotates and engages with the toothed plate 47, making the moving rod 44 move up and down intermittently, and then the fixed frame 42 drives the pressing roller 43 to move up and down, realizing the extrusion of the carton and the outer packaging paper, improving the pressing effect, and conveniently adjusting the up-and-down reciprocating frequency and stroke of the pressing roller 43, thereby adapting to packaging boxes of different sizes. By setting the return spring 52 and the guide rod 51, the moving rod 44 with the toothed plate 47 can maintain stability during up-and-down reciprocating motion, so that the pressing roller 43 can uniformly extrude the carton.
