Description

Technical Field

[0001] This utility model belongs to the field of corrugated cardboard production technology, and in particular relates to a gluing device for corrugated cardboard production. Background Technology

[0002] Corrugated cardboard is a sheet-like material made by bonding face paper, liner paper, core paper and corrugated paper. In the production process of corrugated cardboard, the glue coating process is a crucial step. The uniformity of the glue coating and the precise control of the glue amount directly affect the bonding strength and product quality of the corrugated cardboard.

[0003] Currently, most existing corrugated cardboard coating mechanisms consist of a coating box and a coating roller. The coating roller dips in glue and applies it to the corrugated cardboard, and then the excess glue is scraped off by a scraper. However, this structure not only makes it difficult to control the amount of glue applied, but also causes excess glue to affect the work surface, requiring the addition of a glue collection mechanism to collect the excess glue. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a gluing device for corrugated cardboard production. It features several glue outlets evenly spaced on the bottom side of the gluing box, with glue dispensing pipes fixed at these outlets. Brush bristles are fixed at the glue outlets on the bottom side of the glue dispensing pipes, allowing glue to flow orderly along the pipes onto the bristles, ensuring uniform glue application. A directional valve is installed on the glue dispensing pipes, allowing for easy control of the glue flow rate and avoiding the hassle of removing excess glue.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A corrugated cardboard production gluing device includes a frame, a conveying mechanism, and a gluing mechanism. The frame has legs fixed to its bottom side. The conveying mechanism includes a first motor, a drive roller, a driven roller, and a conveyor belt. The first motor is mounted on the front left side of the frame, and its output shaft extends to the rear end of the frame. The drive roller is fixed to the output shaft of the first motor. The driven roller is rotatably connected to the inner right side of the frame. The drive roller and the driven roller are connected via a conveyor belt. A fixed frame is fixed to the upper middle part of the frame. The fixed frame has a U-shaped structure. Two corresponding screws rotate at the vertical end of the fixed frame. A handle is fixed to the upper end of each screw, and an ear plate is screwed onto the screw. The gluing mechanism includes a gluing box, a glue outlet pipe, and a brush. The adhesive application box is fixed to the inner side of the ear plate. A glue-adding tube is fixed to the glue-adding port on the upper side of the adhesive application box. Several glue outlets are equidistantly opened on the bottom side of the adhesive application box, and glue-dispensing tubes are fixed to each of these outlets. Brush bristles are fixed to the glue outlets on the bottom side of each glue-dispensing tube, and a directional valve is installed on each glue-dispensing tube. The adhesive application box is equipped with a stirring mechanism. By having several glue outlets equidistantly opened on the bottom side of the adhesive application box, and glue-dispensing tubes fixed to each outlet, and by fixing brush bristles to the glue outlets on the bottom side of each glue-dispensing tube, the adhesive flows orderly along the glue-dispensing tubes onto the brush bristles, ensuring the uniformity of the adhesive application. By installing directional valves on the glue-dispensing tubes, the flow rate of the adhesive can be easily controlled by controlling the opening and closing degree of the directional valves, avoiding the trouble of having to clean up excess adhesive again.

[0006] Furthermore, the stirring mechanism includes a rotating shaft, stirring rods, and a second motor. The rotating shaft is rotatably connected inside the glue coating box, and several stirring rods are fixed at equal intervals on the rotating shaft. A second motor connected to the rotating shaft is installed on the front side of the glue coating box. The second motor drives the rotating shaft to rotate, thereby driving the stirring rods to rotate, so as to stir the glue in the glue coating box, prevent the glue from settling or separating, and ensure that the glue concentration is uniform.

[0007] Furthermore, the left and right sides of the bottom of the glue-applying box are inclined inward to avoid excessive glue residue in the glue-applying box and to ensure the glue dispensing effect.

[0008] Compared with the prior art, the beneficial effects of this utility model are: 1. By having several glue outlets evenly spaced on the bottom side of the glue dispensing box, and glue dispensing tubes fixed at the glue outlets, and by fixing brush bristles at the glue outlets on the bottom side of the glue dispensing tubes, the glue flows orderly along the glue dispensing tubes onto the brush bristles, ensuring the uniformity of glue application. By installing a directional valve on the glue dispensing tube, the flow rate of the glue can be easily controlled by controlling the opening and closing degree of the directional valve, avoiding the trouble of generating excess glue that needs to be cleaned again.

[0009] 2. The second motor drives the rotating shaft to rotate, which in turn drives the stirring rod to stir the glue in the coating box, preventing the glue from settling or separating, and ensuring that the glue concentration is uniform. The left and right sides of the bottom of the coating box are tilted inward to avoid excessive glue residue in the coating box and to ensure the glue dispensing effect. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0015] See appendix Figure 1-2As shown, a corrugated cardboard production gluing device includes a frame 1, a conveying mechanism 3, and a gluing mechanism 5. Support legs 2 are fixed to the bottom side of the frame 1. The conveying mechanism 3 includes a first motor 31, a drive roller 32, a driven roller 33, and a conveyor belt 34. The first motor 31 is installed on the front left side of the frame 1, and the output shaft of the first motor 31 extends to the rear end of the frame 1. The drive roller 32 is fixed to the output shaft of the first motor 31. The driven roller 33 is rotatably connected to the inner right side of the frame 1. The drive roller 32 and the driven roller 33 are connected by the conveyor belt 34. A fixed frame 4 is fixed to the upper middle part of the frame 1. The fixed frame 4 has a "U"-shaped structure. Two corresponding screws 6 rotate at the vertical end of the fixed frame 4. A handle 7 is fixed to the upper end of the screws 6, and an ear plate 8 is screwed onto the screws 6. The gluing mechanism 5 includes a gluing box 51, a glue outlet pipe 52, and brush bristles 53. A glue-applying box 51 is fixed inside the ear plate 8 along with a directional valve 54. A glue-applying tube 10 is fixed at the glue-applying port on the upper side of the glue-applying box 51. Several glue outlets are equidistantly opened on the bottom side of the glue-applying box 51. A glue-applying tube 52 is fixed at each of these outlets. A brush bristle 53 is fixed at the glue outlet on the bottom side of the glue-applying tube 52. A directional valve 54 is installed on each of the glue-applying tubes 52. A stirring mechanism 9 is provided inside the glue-applying box 51. By opening several glue outlets equidistantly on the bottom side of the glue-applying box 51 and fixing the glue-applying tube 10 at each outlet, and by fixing the brush bristle 53 at the glue outlet on the bottom side of the glue-applying tube 10, the glue flows orderly along the glue-applying tube 52 onto the brush bristle 53, ensuring the uniformity of glue application. By installing the directional valve 54 on the glue-applying tube 52, the flow rate of the glue can be easily controlled by controlling the opening and closing degree of the directional valve 54, avoiding the trouble of having to clean up excess glue again.

[0016] The stirring mechanism 9 includes a rotating shaft 91, stirring rods 92, and a second motor 93. The rotating shaft 91 is rotatably connected inside the glue coating box 51. Several stirring rods 92 are fixed at equal intervals on the rotating shaft 91. The second motor 93, which is connected to the rotating shaft 91, is installed on the front side of the glue coating box 51. The second motor 93 drives the rotating shaft 91 to rotate, thereby driving the stirring rods 92 to rotate, so as to stir the glue in the glue coating box 51, prevent the glue from settling and separating, and ensure that the glue concentration is uniform.

[0017] The bottom left and right sides of the glue application box 51 are tilted inward to avoid excessive glue residue in the glue application box 51 and to ensure the glue dispensing effect.

[0018] Working principle: Before applying glue, handle 7 can be turned according to the thickness of the corrugated cardboard or the glue application requirements. Handle 7 drives screw 6 to rotate, which in turn moves ear plate 8 and glue application box 51 up and down to adjust the distance between brush bristles 53 and the corrugated cardboard to adapt to different glue application requirements. The corrugated cardboard to be glued is placed on conveyor belt 34. The output shaft of the first motor 31 drives the drive roller 32 to rotate. The drive roller 32 drives the driven roller 33 to rotate through conveyor belt 34, thereby making conveyor belt 34 rotate and conveying the corrugated cardboard towards the glue application mechanism 5. When the corrugated cardboard is conveyed to below the brush bristles 53, the glue in the glue application box 51 flows onto the brush bristles 53 through glue outlet pipe 52. As the conveyor belt 34 moves, the glue is applied to the brush bristles 53. The adhesive is conveyed by brush 53, which evenly applies glue to the surface of the corrugated cardboard to complete the glue application. By setting up a glue application box 51, glue outlet pipe 52, and brush 53, the uniformity of glue application is ensured. By installing a directional valve 54 on the glue outlet pipe 52, the flow rate of glue can be controlled by controlling the opening and closing degree of the directional valve 54, avoiding the trouble of cleaning up excess glue. The second motor 83 drives the rotating shaft 91 to rotate, thereby driving the stirring rod 92 to rotate, so as to stir the glue in the glue application box 51, prevent glue sedimentation and stratification, and ensure uniform glue concentration. The left and right sides of the bottom of the glue application box 51 are inclined inward to avoid excessive glue residue in the glue application box 51, ensuring the glue dispensing effect.
