Description

Technical Field

[0001] This utility model relates to the field of cardboard box slotting technology, specifically a multi-sided slotting device for cardboard box processing. Background Technology

[0002] Multi-sided slotting is a crucial step in cardboard box manufacturing, impacting both the box's forming and ease of use. The main purpose of multi-sided slotting is to cut precise slots and creases into the pre-printed cardboard, facilitating folding and shaping of the box. These slots and creases allow for easy folding, assembly, and sealing during subsequent use, meeting various packaging requirements. Slotting is achieved by the interlocking of an upper curved blade and a lower bottom blade. The bottom blades are typically used in pairs, positioned on either side of the curved blade.

[0003] During the grooving process, the cut paper material easily gets stuck between the two bottom blades. Over time, a significant amount of paper material accumulates between the blades, affecting the subsequent grooving results. Therefore, we propose a multi-faceted grooving device for cardboard box processing. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-faceted slotting device for carton processing. By fixing a horizontal plate parallel to the rotating roller below the bottom knife and fixing a lever plate extending between the bottom plate above the horizontal plate, when the arc-shaped knife and the bottom knife slot the cardboard of the carton, the paper pieces stuck between the bottom knife will eventually be pushed off and cleaned by the lever plate, without affecting the subsequent slotting work, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-sided slotting device for carton processing, comprising side frames, guide rollers, and rotating rollers. Side plates are fixed above the side frames. Four guide rollers are rotatably mounted on both sides of two side plates and between the two sides of two side frames. Two rotating rollers are rotatably mounted between the guide rollers and between two side frames and two side plates. The upper and lower guide rollers and the upper and lower rotating rollers are close to each other. The guide rollers and rotating rollers are connected to stepper motors mounted on their end side plates or side frame surfaces. Multiple arc-shaped blades are evenly mounted on the outer ring of the upper rotating roller. Bottom blades that abut against the arc-shaped blades are mounted on the outer ring of the lower rotating roller located on both sides of the arc-shaped blades. A horizontal plate parallel to the rotating roller is fixed between the side frames below the rotating roller. A lever plate extending to the bottom blades below the rotating roller is vertically fixed above the horizontal plate.

[0006] By adopting the above technical solution, the guide roller drives the cardboard of the carton to pass between the upper and lower rotating rollers. The curved knife and the bottom knife work together to make grooves on the surface of the cardboard. The pieces of paper stuck between the bottom knife will rotate with the rotating rollers and can be pushed off and cleaned by the deflector.

[0007] Optionally, a collection frame is supported between the side frames below the rotating roller, and the collection frame extends to the bottom of the guide rollers on both sides.

[0008] By adopting the above technical solution, the paper scraps that are removed from between the bottom blades can be collected by the collection frame.

[0009] Optionally, support plates are fixed on the upper sides of both sides of the collection frame, and the support plates are placed on the upper part of the support frame below the inner side of the side frame.

[0010] By adopting the above technical solution, the support frame supports the support plate, thereby supporting the collection frame.

[0011] Optionally, a handle is welded and fixed to the surface of the collection frame, and the handle is located on both sides of the collection frame.

[0012] By adopting the above technical solution, the collection box can be easily pulled to the side using the handle to remove it.

[0013] Optionally, the length of the support frame is greater than the length of the support plate, and the support frame extends to both sides of the support plate.

[0014] By adopting the above technical solution, the support plate has a certain sliding length when it is pulled to both sides, which makes it easy to stably support and lift the collection frame.

[0015] Optionally, the bottom sides of the side frame are supported by feet.

[0016] By adopting the above technical solution, the overall structure, including the side frame, is stably supported by the legs.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] 1. The technical solution of this application has a horizontal plate fixed below the rotating roller where the bottom knife is installed, which is parallel to the rotating roller. A baffle plate extending into the bottom plate is fixed above the horizontal plate. When the arc-shaped knife and the bottom knife are used to slot the cardboard of the carton, the paper pieces stuck between the bottom knife will eventually be pushed off and cleaned by the baffle plate, without affecting the subsequent slotting work.

[0019] 2. The technical solution of this application provides a collection frame supported below the rotating roller, so that the paper scraps between the bottom blades can fall into the collection frame and be collected after being pushed down and cleaned, which facilitates subsequent cleaning.

[0024] Please see Figure 1-2 This utility model provides a technical solution: a multi-sided slotting device for carton processing, including a side frame 1, a guide roller 3 and a rotating roller 4. Both sides of the bottom of the side frame 1 are supported by legs 11, and the legs 11 are of the same length to achieve stable support for the side frame 1.

[0025] Side plates 2 are fixed above the side frames 1. The two side plates 2 above the two side frames 1 are parallel to each other. Four guide rollers 3 are rotatably installed on both sides of the two side plates 2 and between the two sides of the two side frames 1. Two rotating rollers 4 are rotatably installed between the two side frames 1 and the two side plates 2 between the guide rollers 3. The upper and lower guide rollers 3 and the upper and lower rotating rollers 4 are close to each other. The guide rollers 3 and rotating rollers 4 are connected to the stepper motors 6 installed on the end side plates 2 or the surface of the side frames 1. In use, the stepper motors 6 drive the upper guide rollers 3 and rotating rollers 4 to rotate clockwise and the lower guide rollers 3 and rotating rollers 4 to rotate counterclockwise. This allows the cardboard to enter the space between the guide rollers 3 from the right and be transported to the left. Conversely, when the stepper motors 6 drive the upper guide rollers 3 and rotating rollers 4 to rotate counterclockwise and the lower guide rollers 3 and rotating rollers 4 to rotate clockwise, the cardboard can enter the space between the guide rollers 3 from the left and be transported to the right. During this process, the side plates 2 on both sides play a central positioning role in the transport of the cardboard.

[0026] In order to achieve the purpose of slotting the cardboard of the carton, multiple curved blades 41 are evenly installed on the outer ring of the upper roller 4, while bottom blades 42 that are close to the curved blades 41 are installed on the outer ring of the lower roller 4 on both sides of the curved blades 41. The curved blades and bottom blades 42 are provided with notches at appropriate positions, so as to be able to open the opening groove of the required length on the surface of the cardboard.

[0027] The cut paper pieces are easily stuck between the bottom blades 42 and rotate with the bottom blades 42, which will affect the grooving effect later. Therefore, a horizontal plate 7 parallel to the rotating roller 4 is fixed between the side frames 1 below the rotating roller 4. A deflector plate 71 extending to the bottom blades 42 below the rotating roller 4 is vertically fixed above the horizontal plate 7. When the paper pieces rotate with the bottom blades 42, they will be deflected by the deflector plate 71 and fall off for cleaning.

[0028] To facilitate the collection of paper scraps, a collection frame 5 is provided between the side frames 1 below the rotating roller 4, and the collection frame 5 extends to the bottom of the guide rollers 3 on both sides. The collection frame 5 can collect the paper scraps that are pulled off. Support plates 51 are fixed on the upper sides of both sides of the collection frame 5. The support plates 51 are supported on the support frame 12 located on the lower inner side of the side frame 1. The length of the support frame 12 is greater than the length of the support plate 51. The support frame 12 extends to both sides of the support plate 51. Handles 52 are welded and fixed to the surface of the collection frame 5. The handles 52 are located on both sides of the surface of the collection frame 5. After use, the collection frame 5 can be pulled by the handle 52 on either side, causing the support plate 51 above it to slide to the side on the surface of the support frame 12 and be pushed out. Finally, the collection frame 5 can be removed to clean up the collected paper scraps.

[0029] In use, the cardboard is conveyed between the side frames 1 extending to both sides. The cardboard is conveyed to the side of the guide roller 3. The stepper motor 6 is started to drive the upper guide roller 3 and the rotating roller 4 to rotate clockwise, and the lower guide roller 3 and the rotating roller 4 to rotate counterclockwise. The cardboard enters the space between the guide rollers 3 from the right and is conveyed to the left. The side plates 2 on both sides play a central positioning role in the cardboard conveying. When passing between the upper and lower rotating rollers 4, the cardboard is grooved on the surface by the upper arc blade 41 and the bottom blades 42 on both sides below. Then it is conveyed to the left and carried away by the conveyor belt. When the bottom blade 42 is driven to rotate by the lower rotating roller 4, the pieces of paper stuck between the two bottom blades 42 are pushed down by the deflector plate 71 and collected in the collection frame 5. When cleaning is needed later, the collection frame 5 can be pulled out and cleaned by the handle 52.
