Description

Technical Field

[0001] This utility model relates to the field of paper box processing technology, and in particular to a cutting device for corrugated paper boxes. Background Technology

[0002] When processing corrugated cardboard boxes, the cardboard usually needs to be cut. Traditional cutting equipment typically uses a cross-cutting machine to cut the cardboard, mainly used to cut corrugated cardboard or similar boards into specific lengths. This type of equipment is usually equipped with one or more fixed straight blades, and the cardboard is moved through the blades to complete the cutting process.

[0003] During cardboard cutting, a significant amount of paper scraps is inevitably generated. Traditional cross-cutting machines typically rely on operators to manually clean the scraps from the work platform. This method not only increases the operator's workload but may also lead to incomplete cleaning, affecting the accuracy of subsequent cuts. Furthermore, after the cardboard is cut, it is usually in a scattered state, requiring the operator to manually remove it from the work platform. This method is not only labor-intensive but also prone to operator fatigue, increasing the risk of operational errors. Additionally, during manual unloading, the operator needs to be close to the high-speed rotating cutting blades, posing a significant safety hazard. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the technical problem of this utility model is to provide a cutting device for corrugated cardboard boxes.

[0005] Technical Solution: A cutting device for corrugated cardboard boxes includes a straight knife, a CNC machine, a second electric push rod, a fixed plate, guide rods, a fan, air pipes, and a pushing assembly. A straight knife is mounted on the CNC machine's work platform. A second electric push rod is mounted on the left side of the CNC machine. A fixed plate is connected to the telescopic rod of the second electric push rod. Two guide rods are connected to the rear side of the CNC machine. The fixed plate is slidably connected to the two guide rods. A fan is mounted on the rear side wall of the fixed plate. Four L-shaped air pipes are equidistantly arranged on the right side of the fixed plate, all of which are connected to and communicate with the fan. Each L-shaped air pipe consists of a vertical section and a horizontal section. Several air outlets are equidistantly arranged along the length of the vertical section. Four sliding grooves are equidistantly opened at the bottom of the CNC machine's work platform, allowing the horizontal section of the air pipe to slide along the grooves. A pushing assembly is located on the right side of the CNC machine.

[0006] Furthermore, it is particularly preferred that each air outlet points diagonally downwards, with the central axis of each air outlet forming a downward tilt angle of 45 degrees with the horizontal plane.

[0007] Furthermore, it is particularly preferred that the pushing component includes a moving platform, a moving block, a moving clamp, a fixed clamp, and a first electric push rod. The moving platform is located on the right side of the CNC machine, and the moving block is slidably connected to the moving platform. The fixed clamp is connected to the rear side of the left side wall of the moving block, and the first electric push rod is installed on the front side of the left side wall of the moving block. The moving clamp is connected to the telescopic rod of the first electric push rod, and the moving clamp is arranged opposite to the fixed clamp.

[0008] Furthermore, it is particularly preferred that both the movable clamp and the fixed clamp have a serrated structure on their inner surfaces.

[0009] In addition, it is particularly preferred that the machine also includes rollers and connecting plates. The connecting plates are symmetrically connected to the front side of the CNC machine, and multiple rollers are equidistantly connected between the connecting plates in a straight line. The rollers are located in front of the CNC machine's work platform and are on the same horizontal plane.

[0010] In addition, it is particularly preferred that the machine also includes a fixed base, a collection box and a handle. The fixed base is connected to the lower front side of the CNC machine, and a collection box for collecting paper scraps is placed on the fixed base. A handle is connected to the front side of the collection box, and the collection box is located below the roller.

[0011] The beneficial effects of this utility model are: 1. The fan blows air continuously through the air pipe, effectively cleaning the debris on the work platform, avoiding the impact of debris on subsequent cutting, and providing a clean working surface for the next cutting, ensuring the smoothness of continuous operation.

[0012] 2. The second electric push rod acts as a power source to control the fixed plate and air pipe to move forward, pushing the cut cardboard onto the roller, thus achieving automatic unloading. This process is fully automated, avoiding direct contact between the operator and the straight blade, and significantly improving operational safety.

[0013] 3. By setting up movable clamps and fixed clamps to clamp and fix the cardboard, and the movable platform controls the left, right and front and back positions of the movable block, the cardboard can be pushed flexibly and can fix cardboard of different specifications, improving the flexibility of the device.

Detailed Implementation

[0019] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Example: A cutting device for corrugated cardboard boxes, such as... Figure 1-Figure 3 As shown, the assembly includes a straight blade 6, a CNC machine 7, a second electric push rod 8, a fixed plate 9, guide rods 10, a fan 12, an air pipe 13, and a pushing assembly. The straight blade 6 for cutting cardboard is mounted on the work platform of the CNC machine 7. When cutting cardboard, the cardboard is placed on the work platform. The second electric push rod 8 is bolted to the left side of the CNC machine 7. The fixed plate 9 is connected to the telescopic rod of the second electric push rod 8. Two guide rods 10 are welded to the rear side of the CNC machine 7. The fixed plate 9 is slidably connected to the two guide rods 10. A fan 12 for cleaning paper scraps is mounted on the rear wall of the fixed plate 9. Four L-shaped air pipes 13 are equidistantly arranged on the right side and pass through it. All air pipes 13 are connected to and communicate with the blower 12. The L-shaped air pipes 13 are composed of vertical and horizontal sections. On the vertical section, several air outlets 14 are equidistantly arranged along its length. The direction of each air outlet 14 is downward. The central axis of each air outlet 14 forms a downward tilt angle of 45 degrees with the horizontal plane to ensure that the gas is accurately blown to the work platform. Four sliding grooves are equidistantly opened at the bottom of the work platform of the CNC machine 7. The horizontal section of the air pipe 13 can slide along the sliding groove. A push component is arranged on the right side of the CNC machine 7.

[0021] like Figure 1 As shown, the pushing component includes a moving platform 1, a moving block 2, a moving clamping plate 3, a fixed clamping plate 4, and a first electric push rod 5. The moving platform 1 is located on the right side of the CNC machine 7. The moving block 2 is slidably connected to the moving platform 1. The moving platform 1 can control the moving block 2 to move in the front-back direction and the left-right direction. The fixed clamping plate 4 is connected to the rear side of the left side wall of the moving block 2. The first electric push rod 5 is bolted to the front side of the left side wall of the moving block 2. The moving clamping plate 3 is connected to the telescopic rod of the first electric push rod 5. The moving clamping plate 3 and the fixed clamping plate 4 are arranged opposite to each other. The two cooperate to clamp and fix the cardboard. The inner surfaces of the moving clamping plate 3 and the fixed clamping plate 4 are provided with a serrated structure, which can increase the friction when fixing the cardboard.

[0022] like Figure 4As shown, it also includes rollers 15 and connecting plates 16. Connecting plates 16 are symmetrically welded to the left and right sides of the front of the CNC machine 7. Multiple rollers 15 are equidistantly connected between the connecting plates 16 in a straight line. The rollers 15 are located in front of the working platform of the CNC machine 7 and are on the same horizontal plane. The cut cardboard will be moved forward on the working platform to the rollers 15, which makes it convenient for the operator to unload the cardboard from the rollers 15 and improves the safety of unloading.

[0023] When cutting corrugated cardboard, firstly, adjust the left and right positions of the moving block 2 according to the width of the cardboard to ensure that the cardboard can be properly fixed. Precise adjustment of the left and right positions of the moving block 2 is achieved by controlling the moving platform 1. Then, the cardboard is placed between the moving clamp 3 and the fixed clamp 4. The moving clamp 3 moves forward or backward by the extension and retraction of the first electric push rod 5, thus firmly clamping the cardboard. Subsequently, the moving platform 1 drives the moving block 2 to move from front to back, feeding the cardboard onto the work platform of the CNC machine 7, so that the cardboard contacts the straight blade 6, and the cutting process begins. During the cutting process, the blower 12 is activated, drawing air into the air pipe 13 and spraying it onto the work platform through the air outlet 14, effectively cleaning debris from the work platform to prevent it from affecting cutting accuracy and providing a clean working surface for the next cut. After the cardboard is cut, it is placed in a dispersed state on the work platform. At this point, the first electric push rod 5 drives the movable clamping plate 3 to reset, releasing the limit on the cardboard. Then, the movable block 2 is moved away via the movable platform 1. Next, the second electric push rod 8 is activated, controlling its extension rod to shorten, driving the fixed plate 9 and the connected fan 12 and air pipe 13 to move forward along the slide until the air pipe 13 contacts the cardboard, thus pushing the cardboard on the work platform forward. During this process, the air outlet 14 continuously blows air, which can further clean the residual paper scraps on the cardboard, providing convenience for the operator. The air pipe 13 pushes the cardboard forward onto the roller 15. When it reaches the limit position, the extension rod of the second electric push rod 8 extends and resets, driving the fixed plate 9, fan 12, and air pipe 13 to move backward and reset. Then, the fan 12 is turned off, completing the automatic unloading process. This design not only improves work efficiency but also ensures operational safety, allowing the operator to easily unload the cut cardboard on the roller 15, away from the straight blade 6, avoiding potential safety risks.

[0024] like Figure 4As shown, it also includes a fixed base 17, a collection box 18, and a handle 19. The fixed base 17 is welded to the lower front side of the CNC machine 7. The collection box 18 for collecting paper scraps is placed on the fixed base 17. The handle 19 is connected to the front side of the collection box 18. The collection box 18 is located below the roller 15. The fan 12 causes the paper scraps to roll forward. When the cardboard is pushed forward by the roller 15, the paper scraps remaining on the cardboard and the work platform will also be carried out and can fall into the collection box 18 through the gap between the rollers 15 to collect the paper scraps.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
