Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box technology, and in particular to a waterproof coating mechanism for corrugated cardboard boxes. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to make corrugated boxes. Corrugated boxes are the most widely used packaging products, and their usage has always been the highest among all packaging products, including calcium-plastic corrugated boxes. During the production process of corrugated boxes, a waterproof coating needs to be applied to the surface of the corrugated cardboard to improve its waterproof performance.

[0003] However, during the production and storage process, the surface of corrugated cardboard is prone to the adhesion of impurities such as dust and paper scraps. If the cardboard is coated directly, these impurities will affect the adhesion between the waterproof coating and the cardboard surface, leading to easy peeling and blistering of the coating, thus reducing the waterproof effect. Therefore, we need to consider how to solve this problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waterproof coating mechanism for corrugated cardboard boxes. This mechanism includes a sleeve, a slider, and a cleaning roller, which allows the cleaning roller to rotate and remove impurities from the cardboard surface. At the same time, the sleeve and slider, in conjunction with a spring, form a buffer, allowing the cleaning roller to flexibly conform to the cardboard surface. This avoids damage to the cardboard through hard contact and is adaptable to cardboard with different flatness, ensuring a stable cleaning effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waterproof coating mechanism for corrugated cardboard boxes includes a workbench. The workbench is characterized by a conveyor belt, a mounting plate fixedly connected to its upper end, and a coating assembly mounted on the mounting plate. The mounting plate is U-shaped, and two hydraulic cylinders are mounted on its upper end. The output ends of both hydraulic cylinders penetrate the mounting plate and are fixedly connected to a lifting plate. The side walls of the lifting plate slide against the inner side walls of the mounting plate. Two sleeves are located below the lifting plate, and sliders are slidably connected to the inner walls of both sleeves. The upper ends of both sliders are fixed... The device is equipped with two movable rods, the upper ends of which extend to the outside and are fixedly connected to the lower end of the lifting plate. The lower ends of the two sleeves are fixedly connected to a U-shaped plate. The upper end of the U-shaped plate is elastically connected to the lower end of the lifting plate through two springs. A cleaning roller is rotatably connected between the inner walls of the two sides of the U-shaped plate. Four connecting plates are fixedly connected to the lower end of the lifting plate. The lower ends of every two cooperating connecting plates are fixedly connected to a suction pipe. The two suction pipes are located on both sides of the cleaning roller. Multiple suction heads are fixedly connected to the opposite sides of the two suction pipes.

[0007] Preferably, the lower end of the workbench is fixedly connected to a plurality of support legs, and the lower end of each support leg is provided with anti-slip texture.

[0008] Preferably, a motor is installed on the outer wall of the U-shaped plate, and the end of the output shaft of the motor passes through the U-shaped plate and is fixedly connected to one end of the cleaning roller.

[0009] Preferably, a support plate is fixedly connected to the upper end of the mounting plate. The support plate is U-shaped and a collection box is fixedly connected to its upper end. A filter screen is installed inside the collection box, and two door panels are hinged to the outer side wall of the collection box.

[0010] Preferably, a suction fan is installed at the upper end of the collection box, the suction end of the suction fan is connected to the top space of the collection box, and a branch pipe is connected to the bottom space of the collection box. The other two ends of the branch pipe are respectively connected to the inside of two suction pipes.

[0011] Preferably, the upper end of the workbench is fixedly connected to two fixed plates, and electric telescopic rods are installed on the opposite sides of the two fixed plates. The telescopic ends of the two electric telescopic rods pass through the corresponding fixed plates and are fixedly connected to a movable plate. Multiple guide rollers are rotatably connected to the opposite sides of the two movable plates.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The structure includes a slider, a moving rod, and a spring. The elastic deformation of the spring, combined with the sliding of the slider within the sleeve and the up-and-down extension of the moving rod, enables flexible contact between the cleaning roller and the cardboard surface. This avoids hard contact that could cause indentations or damage to the cardboard, ensuring that the cleaning roller always adheres to the cardboard and guaranteeing a stable cleaning effect.

[0014] 2. The structure includes a dust suction pipe, branch pipes, and a vacuum fan. Under the negative pressure generated by the vacuum fan, the dust and impurities generated when the cleaning roller cleans the cardboard are collected through the dust suction pipe. This avoids dust pollution of the environment and secondary adhesion to the cardboard, which affects the coating quality and further improves the cleanliness of the cardboard surface.

[0015] 3. The structure is equipped with electric telescopic rods, moving plates, and guide rollers. The spacing of the moving plates can be adjusted by the electric telescopic rods to adapt to corrugated cardboard of different widths, improving the versatility of the mechanism. At the same time, the guide rollers can rotate with the cardboard conveying, which not only assists in conveying but also prevents the cardboard from deviating, ensuring the stable operation of subsequent coating processes.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-7 A waterproof coating mechanism for corrugated cardboard boxes includes a workbench 1. Multiple support legs 2 are fixedly connected to the lower end of the workbench 1. Each support leg 2 has anti-slip textures at its lower end. A conveyor belt 3 is installed on the workbench 1. The conveying speed of the conveyor belt 3 can be adjusted by an external control system to adapt to the coating requirements of corrugated cardboard boxes of different specifications. An mounting plate 4 is fixedly connected to the upper end of the workbench 1. A coating component 5 is installed on the mounting plate 4. The coating component 5 is prior art and will not be described in detail here. The mounting plate 4 is U-shaped and has two hydraulic cylinders 6 installed at its upper end. The output ends of the two hydraulic cylinders 6 pass through the mounting plate 4 and are fixedly connected to a lifting plate 7. The hydraulic cylinders 6 can drive the lifting plate 7 to move up and down. The two side walls of the lifting plate 7 slide against the two side inner walls of the mounting plate 4.

[0026] The lifting plate 7 has two sleeves 8 below it. The inner walls of the two sleeves 8 are slidably connected to sliders 9. The upper ends of the two sliders 9 are fixedly connected to moving rods 10. The upper ends of the two moving rods 10 extend to the outside and are fixedly connected to the lower end of the lifting plate 7. The lower ends of the two sleeves 8 are fixedly connected to a U-shaped plate 11. The upper end of the U-shaped plate 11 is elastically connected to the lower end of the lifting plate 7 through two springs 12. A cleaning roller 13 is rotatably connected between the inner walls of the two sides of the U-shaped plate 11. The cleaning roller 13 is a brush roller. When the cleaning roller 13 contacts the surface of the corrugated cardboard, the springs 12 will generate corresponding elastic deformation according to the flatness of the cardboard surface. Through the sliding of the sliders 9 in the sleeves 8 and the up and down movement of the moving rods 10, the cleaning roller 13 makes flexible contact with the cardboard surface. This can avoid cardboard indentation or damage caused by hard contact between the cleaning roller 13 and the cardboard surface, while ensuring that the cleaning roller 13 can fit the cardboard surface and improve the cleaning effect.

[0027] Among them, a motor 14 is installed on the outer wall of the U-shaped plate 11. The motor 14 is a servo motor. The end of the output shaft of the motor 14 passes through the U-shaped plate 11 and is fixedly connected to one end of the cleaning roller 13. Under the drive of the motor 14, the cleaning roller 13 can rotate to remove dust and other impurities from the surface of the corrugated cardboard. Four connecting plates 15 are fixedly connected to the lower end of the lifting plate 7. The lower ends of each pair of mutually cooperating connecting plates 15 are fixedly connected to a suction pipe 16. The two suction pipes 16 are located on both sides of the cleaning roller 13. Multiple suction heads 17 are fixedly connected to the opposite sides of the two suction pipes 16. The multiple suction heads 17 are inclined and evenly distributed on the suction pipes 16. A support plate 18 is fixedly connected to the upper end of the mounting plate 4. The support plate 18 is U-shaped and a collection box 19 is fixedly connected to its upper end. A filter screen 20 is installed inside the collection box 19. Two door panels 21 are hinged to the outer wall of the collection box 19.

[0028] The upper part of the collection box 19 is equipped with a suction fan 22, the suction end of which is connected to the top space of the collection box 19. The bottom space of the collection box 19 is connected to a branch pipe 23, which is made of a flexible and aging-resistant rubber hose. The other two ends of the branch pipe 23 are connected to the inside of two suction pipes 16 respectively. Under the negative pressure of the suction fan 22, the suction head 17 can suck up the dust and fine impurities generated during cleaning, and then transport them to the collection box 19 through the branch pipe 23. The filter screen 20 filters and traps the air, and clean air is discharged from the suction fan 22, further ensuring the cleanliness of the cardboard surface. The upper part of the workbench 1 Two fixed plates 24 are fixedly connected, and electric telescopic rods 25 are installed on opposite sides of the two fixed plates 24. The telescopic ends of the two electric telescopic rods 25 pass through the corresponding fixed plates 24 and are fixedly connected to movable plates 26. The distance between the two movable plates 26 can be adjusted by telescopically extending and retracting the electric telescopic rods 25 to accommodate corrugated cardboard of different widths. Multiple guide rollers 27 are rotatably connected to the opposite sides of the two movable plates 26. During the corrugated cardboard conveying process, the guide rollers 27 can rotate with the movement of the cardboard, playing a guiding and auxiliary conveying role, preventing the cardboard from shifting during the conveying process, and improving the accuracy of the coating process.

[0029] In this utility model, when in use, firstly, according to the size specifications of the corrugated cardboard to be processed, the conveying speed of the conveyor belt 3 is adjusted through the external control system. At the same time, two electric telescopic rods 25 are started to drive two moving plates 26 to move until the distance between the two moving plates 26 is adapted to the width of the cardboard. Then, two hydraulic cylinders 6 are started to drive the lifting plate 7 to move up and down, thereby driving the cleaning roller 13 and the dust suction pipe 16 to rise and fall until the cleaning roller 13 reaches the cleaning position.

[0030] Then, the staff places the corrugated cardboard on the conveyor belt 3 for conveying. During the conveying process, the cardboard first enters between two moving plates 26. Multiple guide rollers 27 will rotate with the cardboard to guide and assist in the conveying of the cardboard, prevent the cardboard from deviating, and ensure that it enters the cleaning area. After entering the cleaning area, the motor 14 and the suction fan 22 can be started. After the motor 14 starts, it will drive the cleaning roller 13 to rotate. The rotating cleaning roller 13 adheres to the surface of the cardboard under the elastic action of the spring 12 to remove dust and other impurities from its surface. After the suction fan 22 starts, it will create a negative pressure in the collection box 19. The negative pressure is transmitted to the two suction pipes 16 through the branch pipe 23. In this way, the dust and fine impurities generated during cleaning will be sucked into the suction pipe 16 through the suction head 17, and then transported to the collection box 19 through the branch pipe 23. After being filtered by the filter screen 20 in the collection box 19, the impurities are trapped at the bottom of the collection box 19, and the filtered clean air is discharged from the suction fan 22.

[0031] After cleaning, the corrugated cardboard continues to move along the conveyor belt 3 and enters the working area of ​​the coating component 5. At this time, the coating component 5 can be activated. The coating component 5 sprays the waterproof coating evenly onto the surface of the cardboard according to the preset coating parameters. The corrugated cardboard with the waterproof coating completed will be sent out from the output end of the mechanism along the conveyor belt 3. The staff can then carry out subsequent collection and processing. If continuous processing is required, simply repeat the above process. If processing is completed or maintenance is required, turn off the power of each device, open the two door panels 21, and the filter screen 20 can be cleaned or replaced, and the inside of the collection box 19 can be cleaned.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
