Technical Field
[0001] This utility model belongs to the field of automated cardboard box processing technology, and in particular relates to a glue application device for automated cardboard box processing. Background Technology
[0002] A cardboard box is a packaging container made of cardboard. It is usually multi-layered and the layers are mostly connected by glue. Therefore, in the automated processing and production of cardboard boxes, glue application equipment is often required.
[0003] Chinese utility model patent CN220995607U discloses a gluing device for cardboard box processing. This device utilizes an electric cylinder, and through the coordinated operation of a connecting plate, glue storage box, long plate, motor, ring rail, ring groove, and limiting plate, it achieves the gluing process for cardboard boxes. This solves the problems of low automation and inefficiency caused by manual gluing, as well as the tendency for manual operation to result in substandard gluing areas. However, during the bonding of multiple layers of cardboard, the surface of the cardboard is prone to retaining impurities such as paper scraps from previous processes, and the device lacks a function to clean these impurities. The presence of these impurities affects the bonding strength between the cardboard layers, reducing the quality of the produced cardboard boxes.
[0004] Therefore, there is an urgent need to improve existing gluing devices for cardboard box processing and provide an automated gluing device for cardboard box processing that has a cleaning function and can clean residual impurities from cardboard boxes and other materials. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a reasonably designed and simple gluing device for automated cardboard box processing that can clean residual impurities from cardboard boxes, thereby solving the problems existing in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A glue-applying device for automated cardboard box processing includes a processing table. A fixed rod is fixedly installed on the upper rear left end of the processing table, and a cleaning component is installed at the top of the fixed rod. A fixed frame is fixedly installed on the upper right side of the processing table. A movable frame is slidably provided on the inner side of the fixed frame. A glue storage box and an electric push rod are fixedly installed on the top of the fixed frame. Two electric push rods are located on the front and rear sides of the glue storage box, respectively. The telescopic ends of the electric push rods are fixedly connected to the movable frame. A leveling component is provided on the left side of the movable frame. A glue-applying roller is installed on the inner bearing at the bottom of the movable frame. A second motor is fixedly installed at the front bottom of the movable frame. The output end of the second motor is fixedly connected to the glue-applying roller. Multiple glue dispensing valves are equidistantly arranged on the upper left side of the glue-applying roller. The glue dispensing valves are fixedly connected to the movable frame. A glue delivery hose is fixedly connected to the top of each glue dispensing valve. The other end of the glue delivery hose is fixedly connected to the glue storage box.
[0008] Preferably, the cleaning assembly includes a movable rod, a first motor, a first gear, an unwinding shaft, a rewinding shaft, and a second gear. The unwinding shaft is mounted on the top bearing of the fixed rod. The movable rod is sleeved on the outer bearing of the rear end of the unwinding shaft. The rewinding shaft is mounted on the bearing at the end of the movable rod away from the unwinding shaft. The rear ends of both the rewinding shaft and the unwinding shaft are fixedly connected to the second gear. The first motor is fixedly mounted in the middle of the movable rod. The output end of the first motor is fixedly connected to the first gear. The first gear is meshed with both of the second gears.
[0009] Preferably, the cleaning assembly also includes an adhesive tape with its two ends wound around the outside of the unwinding shaft and the rewinding shaft, respectively, and the adhesive side of the tape is located on the side closest to the processing table.
[0010] Preferably, a second connecting rod is hinged to the bottom middle part of the movable rod, a first connecting rod is slidably sleeved on the outer side of the second connecting rod, a tension spring is fixedly connected between the first connecting rod and the second connecting rod, and the bottom end of the first connecting rod is hinged to the fixed rod.
[0011] Preferably, the leveling assembly includes a support rod, a limiting block, a scraper, and a nut. Both support rods are fixed on the left side of the movable frame and are arranged symmetrically front to back. The limiting block is fixedly sleeved on the outer side of the middle part of the support rod. The scraper is slidably sleeved on the outer side of the support rod and located to the left of the limiting block. The outer wall of the end of the support rod away from the movable frame is provided with a threaded structure, and the nut is sleeved on the external thread of the threaded structure.
[0012] Preferably, the scraper and the support rod form a detachable structure, the scraper is inclined, and the distance between the bottom end of the scraper and the coating roller is 1mm.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] In this invention, when the cardboard is being transported, the first motor is started. Two second gears meshing with the first gear control the unwinding shaft and the rewinding shaft to rotate synchronously in the same direction, thus conveying the tape. The tape facilitates the removal of paper scraps and impurities attached to the cardboard. As the tape winds more on the rewinding shaft, the movable rod automatically deflects upward. During this process, a tension spring ensures that the tape outside the rewinding shaft adheres tightly to the cardboard, guaranteeing the removal of impurities and ensuring the smooth progress of subsequent gluing work.
[0015] This invention utilizes multiple glue dispensing valves to drip glue onto the coating roller in a measured amount. When the second motor is started to control the coating roller to rotate counterclockwise, a scraper can evenly spread the glue on the surface of the coating roller, facilitating uniform glue application to the conveyed cardboard. Furthermore, the use of two electric push rods at the front and rear, as well as the glue delivery hose, allows for the vertical lifting and lowering adjustment of the movable frame and the coating roller, making the device suitable for the production and processing of cartons of different thicknesses.

The winding shaft 35 is mounted on the bearing at the end of the movable rod 31 away from the unwinding shaft 34. The rear ends of both the winding shaft 35 and the unwinding shaft 34 are fixedly connected to the second gear 36. The first motor 32 is fixedly mounted in the middle of the movable rod 31. The output end of the first motor 32 is fixedly connected to the first gear 33. The first gear 33 is meshed with both second gears 36.
[0027] As a preferred embodiment, based on the above structure, the cleaning component 3 further includes an adhesive tape 37, with both ends of the adhesive tape 37 wound around the outside of the unwinding shaft 34 and the rewinding shaft 35, respectively, and the adhesive surface of the adhesive tape 37 is located on the side of it closest to the processing table 1.
[0028] In this embodiment, when the first motor 32 is started to control the first gear 33 to rotate, two second gears 36 that mesh with the first gear 33 are used to control the unwinding shaft 34 and the winding shaft 35 to rotate synchronously in the same direction, which facilitates the control of the conveyor belt 37. The conveyor belt 37 is used to remove paper scraps and impurities attached to the cardboard.
[0029] As a preferred embodiment, based on the above structure, the middle bottom end of the movable rod 31 is further hinged to a second connecting rod 5, the outer side of the second connecting rod 5 is slidably sleeved with a first connecting rod 4, a tension spring 6 is fixedly connected between the first connecting rod 4 and the second connecting rod 5, and the bottom end of the first connecting rod 4 is hinged to the fixed rod 2.
[0030] In this embodiment, the tension spring 6 is used to ensure that the movable rod 31 is always pulled downward, so that the tape 37 outside the rewind shaft 35 can be tightly attached to the cardboard, ensuring that impurities are removed and that the subsequent gluing work can proceed smoothly.
[0031] In a preferred embodiment, based on the above structure, the leveling component 9 further includes a support rod 91, a limiting block 92, a scraper 93, and a nut 94.
