Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, and in particular to a dust removal pretreatment device for the surface of cardboard box film. Background Technology

[0002] Cardboard boxes are lightweight packaging containers made of corrugated cardboard. They are widely used due to their low cost, ease of processing, and environmental friendliness. Before lamination, the surface of the cardboard box is cleaned to remove dust, as dust can seriously affect the adhesion of the film. The purpose of cleaning is to ensure that the lamination is flat and firm, enhance the aesthetics, moisture resistance, and abrasion resistance of the packaging, thereby better protecting the contents. Cardboard boxes are mainly used in the packaging and transportation of goods in the fields of logistics, food and beverage, electronic products, and daily consumer goods.

[0003] Existing pre-treatment devices for dust removal on the surface of cardboard boxes for lamination only use ordinary cleaning rollers combined with vacuum cleaners for dust removal and cleaning. Since the dust adhering to the surface of the cardboard box may have clumped during the previous production stage, ordinary cleaning rollers alone cannot completely clean the clumped dust. As a result, when the cardboard box with dust still on the surface is transported to the next step for lamination, the lamination effect is poor and the quality of the finished product is reduced.

[0022] Reference Figures 1-5 In a preferred embodiment, the vibration cleaning component 4 includes: Fixed plates 401 are fixedly connected to the two sides of the end of the setting frame 8 near the feed inlet. Adjustable telescopic rods 402 are respectively provided on the upper side of the two fixed plates 401. Rotating blocks 403 are fixedly connected to the telescopic ends of the two adjusting telescopic rods 402. The two rotating blocks 403 slide in the corresponding sliding grooves opened in the setting frame 8. Rotating holes are opened on the opposite side of the two rotating blocks 403. The same rotating rod 405 is connected to the two rotating holes through bearings.

[0023] In this solution, the vibration cleaning component 4 also includes: A rotary motor 409 is fixedly connected to one side of one of the rotating blocks 403, and the drive end of the rotary motor 409 is connected to one end of the rotating rod 405 via a coupling. Two connecting blocks 408 are fixedly connected to the outer wall of the rotating rod 405 at equal intervals. The two connecting blocks 408 are located inside the mounting frame 8. The upper and lower ends of the two connecting blocks 408 are fixedly connected to the slide rail frame 404. Two L-shaped fixing plates 410 are fixedly connected to both sides of the multiple slide rail frames 404.

[0024] In this solution, the vibration cleaning component 4 also includes: Vibration rod 406, two vibration rods 406 are connected to the interior of two sets of L-shaped fixed plates 410 located on the same horizontal line by bearings, and rotating dial plates 414 are fixedly connected to the outer walls of the two ends of the two vibration rods 406 respectively. The multiple rotating dial plates 414 rotate inside the square grooves opened on both sides of the corresponding slide frame 404.

[0026] When cleaning the surface of the cardboard box, the two wave plates on the rotating dial 414 continuously rotate the T-shaped sliding plate 412 in a circular motion, and at the same time, the return spring 413 causes the replaceable cleaning plate 411 to repeatedly press against the surface of the cardboard box. Under the action of the vibrating conveyor table 2 and multiple vibrating springs 10, the cardboard box can achieve high-frequency vibration. The dust clumps on the surface of the cardboard box are dislodged by vibration. When the replaceable cleaning plate 411 contacts the surface of the cardboard box, it can initially remove the dust adhering to the surface of the cardboard box, thereby improving cleaning efficiency. The two replaceable cleaning plates 411 can be switched back and forth and the work process can be completed quickly without interruption, ensuring that each cardboard box receives a preliminary uniform level of cleaning while improving work efficiency.

[0027] Reference Figure 1 , Figure 2 and Figure 6 In a preferred embodiment, a lifting cylinder 11 is provided on the upper inner wall of the mounting frame 8. A dust collection hood 12 is fixedly connected to the telescopic end of the lifting cylinder 11. Cleaning holes are respectively opened on the outer walls of both ends of the dust collection hood 12. The same cleaning roller 13 is connected to the two opposing cleaning holes through bearings. A vacuum cleaner 6 is provided on the upper side of the mounting frame 8. One end of the two suction pipes 7 is provided on both sides of the vacuum cleaner 6. The other ends of the two suction pipes 7 pass through the outer wall of the mounting frame 8 and are inserted into the inside of the dust collection hood 12. The two sides of the limiting slide seat 1 are equally spaced. A vibrating chute is provided at a distance from the opening. A vibrating conveyor table 2 is slidably connected inside the vibrating chute. One end of a plurality of vibrating springs 10 is fixedly connected at equal intervals to the lower side of both ends of the vibrating conveyor table 2. The other end of the plurality of vibrating springs 10 is fixedly connected to the inner wall of the lower end of the limiting chute seat 1. A conveying groove is provided on the upper side of the vibrating conveyor table 2. A conveying through hole is provided inside both ends of the vibrating conveyor table 2. A conveying shaft 5 is connected to the two conveying through holes through bearings. The two conveying shafts 5 are provided with the same conveyor belt 9 on the outer wall inside the conveying groove.

[0028] When removing dust from the surface of the carton, the vacuum cleaner 6 and the dust cover 12 prevent the dust from flying and causing secondary pollution. At the same time, the cleaning roller 13 performs secondary cleaning on the carton to further improve the cleaning effect while ensuring the flatness of the carton surface so as to improve the adhesion of the film when it is laminated later.

[0029] Working principle: First, the operator adjusts the corresponding vibratory cleaning component 4 and cleaning roller 13 to the appropriate height according to the thickness of the cardboard box using two adjusting telescopic rods 402 and a lifting cylinder 11. Then, the cardboard box is placed on the vibratory conveyor table 2, and the conveyor belt 9 is driven by the conveyor motor 3 to transport the cardboard box. When the cardboard box reaches the position of the vibratory cleaning component 4, the two rotating plates 414 rotate and actuate the corresponding T-shaped sliding plates 412, driven by the vibratory motor 417 and the vibratory rod 406. Under the action of the rotating plates 414, the two T-shaped sliding plates 412 overcome the tension of the two corresponding reset springs 413 and descend. As the two T-shaped sliding plates 412 descend, the slide rail plate 407 drives the replaceable cleaning plate 411 to descend and squeeze... The vibrating conveyor 2 slides inside the limiting slide seat 1 and is suspended under the action of multiple vibrating springs 10. Therefore, when the replaceable cleaning plate 411 presses against the surface of the cardboard box, the cardboard box will descend together with the vibrating conveyor 2. During this process, the two wave plates on the rotating dial plate 414 continuously rotate the T-shaped sliding plate 412, and in conjunction with the action of the return spring 413, the replaceable cleaning plate 411 repeatedly presses against the surface of the cardboard box. Under the action of the vibrating conveyor 2 and multiple vibrating springs 10, the cardboard box can achieve high-frequency vibration. The vibration causes the dust clumps on the surface of the cardboard box to fall off. In addition, when the replaceable cleaning plate 411 contacts the surface of the cardboard box, it can initially remove the dust adhering to the surface of the cardboard box, improving cleaning efficiency. When the adhesion function of the replaceable cleaning plate 411 decreases, the operator can rotate the entire vibrating cleaning assembly 4 by rotating the rotating rod 405 via the rotating motor 409 before the next carton enters. This rotates another spare replaceable cleaning plate 411 to the vibrating conveyor table 2 to continue working. Since the replaceable cleaning plate 411 with decreased adhesion function is engaged with two fixed ratchet plates 415 connected by a compression spring 416 in the slide rail 407, the operator only needs to push one end with a tool to push out the replaceable cleaning plate 411 with decreased adhesion function. Then, a brand new replaceable cleaning plate 411 is aligned with the slide rail 407 and inserted back into place. Under the action of the two fixed ratchet plates 415, it can... The replaceable cleaning plate 411 is firmly fixed. During this process, the two replaceable cleaning plates 411 can be switched back and forth without interrupting the work process, so as to achieve quick disassembly and assembly. This ensures that each carton is initially cleaned to a uniform degree while improving work efficiency. When the carton is initially cleaned and then conveyed to the cleaning roller 13, the surface of the carton is cleaned a second time by the cleaning roller 13. At the same time, the vacuum cleaner 6 is used to remove dust through the vacuum hood 12 and enter the vacuum cleaner 6 through the two vacuum pipes 7. During this process, the vacuum cleaner 6 and the vacuum hood 12 prevent the cleaning dust from flying and causing secondary pollution. At the same time, the cleaning roller 13 cleans the carton a second time to further improve the cleaning effect while ensuring the flatness of the carton surface so as to improve the adhesion of the lamination when it is laminated later.
