Description

Technical Field

[0001] This application relates to the field of cutting equipment technology, and more specifically, to a cutting device for carton production. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. In the production process of cardboard boxes, the raw cardboard must first be cut to ensure that the size is consistent for subsequent production. Currently, the cutting of cardboard boxes is mostly done by having workers press down on the cardboard box with one hand to limit its position, while using the other hand to hold the cutting tool and cut the box along the marked size lines. This is not only time-consuming and labor-intensive, resulting in low cutting efficiency, but also makes the cardboard box less stable after being limited by the above method. This can easily lead to crooked edges after the cardboard box is cut, which in turn affects the normal use of the cardboard box. Utility Model Content

[0003] To address the shortcomings of the existing technology, the purpose of this application is to provide a cutting device for carton production, including a workbench and a carton placed horizontally on top of the workbench. Multiple L-shaped support frames are vertically formed on the workbench, with each L-shaped support frame tilting towards the front and rear sides of the top of the workbench and facing each other. A pressure plate is driven to be installed inside each L-shaped support frame, and the pressure plates are horizontally positioned above the carton. The pressure plates rise and fall within the L-shaped support frames to press and limit the front and rear sides of the top of the carton. A swing frame is obliquely installed on the top of the workbench, with one end of the swing frame hinged to the workbench. A drive motor is horizontally installed on the outer side of the workbench, and one end of the drive motor drives a saw blade, which is obliquely positioned between the pressure plates. The top of the saw blade slides against the bottom of the swing frame, and the drive motor drives the saw blade to reciprocate obliquely at the bottom of the swing frame, thereby cutting the carton located on top of the workbench.

[0004] Preferably, each of the L-shaped support frames is equipped with a first cylinder, and the first cylinder is vertically located at the top of the L-shaped support frame, and one end of the first cylinder is driven and connected to the pressure plate.

[0005] Preferably, a saw blade frame is horizontally mounted on the top of the saw blade, and the saw blade and the saw blade frame move synchronously. The saw blade slides between the saw blade frame and the bottom of the swing frame, and the drive motor drives the saw blade frame and the saw blade together to move obliquely back and forth at the bottom of the swing frame.

[0006] Preferably, the saw blade frame is formed with a dovetail tenon, which is located laterally at the top of the saw blade frame and moves synchronously with the saw blade frame. The bottom of the swing frame is formed with a dovetail groove that slides with the dovetail tenon, and both ends of the dovetail groove extend laterally through the left and right sides of the swing frame. The saw blade frame slides with the bottom of the swing frame through the mutual cooperation between the dovetail groove and the dovetail tenon.

[0007] Preferably, a tie rod is horizontally arranged on the outer side of the saw blade frame, and one end of the tie rod is driven to the saw blade frame. The saw blade is driven to the tie rod through the saw blade frame. A rotating wheel is rotatably arranged below the swing frame, and the rotating wheel is horizontally located on the inner side of the workbench. One end of the drive motor is driven to the rotating wheel, and the other end of the tie rod is driven to the rotating wheel. The saw blade frame is driven to the rotating wheel through the tie rod, and the drive motor drives the rotating wheel to rotate below the swing frame, thereby causing the tie rod and the saw blade to move obliquely back and forth at the bottom of the swing frame.

[0008] Preferably, a cylinder frame is provided on the side of the workbench, and a second cylinder is vertically provided at the bottom of the cylinder frame. The second cylinder passes through the cylinder frame and is driven to the other end of the swing frame. The second cylinder drives the swing frame to deflect at an angle at the top of the workbench.

[0009] Preferably, the bottom of the side of the L-shaped support frame is formed with a limiting groove, and the limiting groove extends horizontally through the L-shaped support frame. The carton is horizontally located in the limiting groove and both sides of the carton are in contact with the sides of the limiting groove.

[0010] Preferably, the workbench is formed with multiple shelves for supporting cartons, and the shelves are located laterally on the front and rear sides of the workbench, with the top of each shelf flush with the top of the workbench.

[0011] In summary, the beneficial effects of this application are as follows:

[0012] When workers need to cut cardboard boxes, the initial positions of the saw blade and pressure plate are as follows: the saw blade is angled upwards from left to right above the cardboard box, and the pressure plate is not in contact with the box. After the cardboard box is placed horizontally on the top of the workbench, the pressure plate is driven down until its bottom contacts the front and rear sides of the top of the cardboard box. This, through the interaction between the pressure plate and the workbench, confines the cardboard box to the top of the workbench. Once the box is in position, the worker drives the movable end of the swing frame downwards, causing the saw blade to swing downwards as well. Both the swing frame and the saw blade change from an angle of left-lower-right-high to a left-higher-right-lower position and continue swinging downwards, bringing the saw blade closer to the cardboard box until the saw teeth on the blade contact the right edge of the top of the cardboard box. Then, the drive motor is driven to rotate, causing the saw blade to move downwards from the bottom of the swing frame. The saw blade moves diagonally back and forth, and during this diagonal back and forth movement, the swing frame continues to drive the saw blade to swing downwards, allowing the saw teeth on the blade to continuously cut the cardboard box until it is completely cut. At this point, the cutting of the cardboard box located at the top of the workbench is complete. Through the cooperation of the above structures, the manual method of pressing and limiting the cardboard box with one hand while holding the cutting tool with the other hand to cut the cardboard box is replaced. This effectively solves the current problem that most cardboard box cutting work involves workers pressing and limiting the cardboard box with one hand while holding the cutting tool with the other hand to cut the cardboard box along the marked dimensions. This method is not only time-consuming and labor-intensive, resulting in low cutting efficiency, but also makes the cardboard box less stable after being limited by the above method, which can easily lead to crooked edges after cutting, thus affecting the normal use of the cardboard box.

[0022] A cutting device for cardboard box production, see [link / reference] Figures 1 to 4The system includes a workbench 1 and a cardboard box 2 placed horizontally on top of the workbench 1. Multiple L-shaped support frames 3 are vertically formed on the workbench 1, with each L-shaped support frame 3 pointing towards the front and rear sides of the top of the workbench 1, and the L-shaped support frames 3 are distributed opposite each other. A pressure plate 4 is driven to be installed inside each L-shaped support frame 3, and the pressure plates 4 are all horizontally positioned above the cardboard box 2. The pressure plates 4 rise and fall within the L-shaped support frames 3 to press and limit the front and rear sides of the top of the cardboard box 2. A swing frame 5 is obliquely installed on the top of the workbench 1, and one end of the swing frame 5 is hinged to the workbench 1. Next, a drive motor 6 is horizontally arranged on the outer side of the workbench 1, and a saw blade 7 is connected to one end of the drive motor 6. The saw blade 7 is obliquely located between the pressure plates 4. The top of the saw blade 7 is slidably engaged with the bottom of the swing frame 5, and the drive motor 6 drives the saw blade 7 to move obliquely back and forth at the bottom of the swing frame 5, thereby cutting the carton 2 located at the top of the workbench 1. In this embodiment, when the worker needs to cut the carton 2, the initial position of the saw blade 7 and the pressure plate 4 is: the saw blade 7 is obliquely located above the carton 2 with the left side lower and the right side higher, and the pressure plates 4 do not contact the carton 2.After the carton 2 is placed horizontally on top of the workbench 1, the pressure plate 4 is driven down until its bottom contacts the front and rear sides of the top of the carton 2. Through the cooperation between the pressure plate 4 and the workbench 1, the carton 2 is confined to the top of the workbench 1. Once the carton 2 is in place, the operator drives the movable end of the swing frame 5 to swing downwards, causing the saw blade 7 to swing downwards as well. At this time, both the swing frame 5 and the saw blade 7 change from a left-low, right-high position to a left-high, right-low position and continue to swing downwards, causing the saw blade 7 to move closer to the carton 2 until the saw teeth on the saw blade 7 contact the right edge of the top of the carton 2. Then, the drive motor 6 is driven to rotate. As the drive motor 6 rotates, it drives the saw blade 7 to move diagonally back and forth at the bottom of the swing frame 5. During this diagonal back and forth movement, the swing frame 5 continues to drive the saw blade 7 to swing downwards, allowing the saw teeth on the saw blade 7 to continuously cut the carton 2 until the saw blade 7 completely cuts it off. At this point, the carton 2 is successfully confined. The cutting of cardboard boxes 2 at the top of workbench 1 involves repeating the reverse steps to return the swing frame 5, saw blade 7, and pressure plate 4 to their initial positions. This allows the remaining cardboard boxes 2 to be in a movable state, enabling adjustment of their cutting position. After adjustment, the same steps are repeated to cut the remaining boxes. This coordinated operation replaces the manual method of pressing and limiting the cardboard box 2 with one hand while simultaneously using a cutting tool to cut it. This effectively solves the current problem of cardboard box cutting, where workers typically press and limit the box with one hand while using the other to cut along the defined dimensions. This method is time-consuming, labor-intensive, and inefficient. Furthermore, the cardboard box 2, after being limited in this way, is not stable enough, leading to skewed edges after cutting and affecting its subsequent use.

[0023] Each of the L-shaped support frames 3 is equipped with a first cylinder 8, which is vertically located at the top of the L-shaped support frame 3. One end of the first cylinder 8 is driven and connected to the pressure plate 4. In this embodiment, when the worker places the carton 2 on the top of the workbench 1, the first cylinder 8 drives the pressure plate 4 to descend inside the L-shaped support frame 3 until the bottom of the pressure plate 4 contacts the front and rear sides of the top of the carton 2. Then, with the cooperation of the pressure plate 4 and the workbench 1, the carton 2 is pressed and fixed at the top of the workbench 1. When it is necessary to cut the remaining carton 2, the first cylinder 8 drives the pressure plate 4 to rise inside the L-shaped support frame 3 until the bottom of the pressure plate 4 does not contact the top of the carton 2. At this time, the carton 2 will be in an infinite position, and the cutting position of the remaining carton 2 can be adjusted. Through the cooperation between the above structures, the stability of this embodiment is effectively improved.

[0024] The saw blade 7 is horizontally mounted on the top of the saw blade 7, and the saw blade 7 and the saw blade frame 9 move synchronously. The saw blade 7 slides with the bottom of the swing frame 5 through the saw blade frame 9 and the drive motor 6 drives the saw blade frame 9 and the saw blade 7 to move obliquely back and forth at the bottom of the swing frame 5.

[0025] The saw blade frame 9 has a dovetail tenon 10 formed on it, and the dovetail tenon 10 is located laterally at the top of the saw blade frame 9. The dovetail tenon 10 moves synchronously with the saw blade frame 9. The bottom of the swing frame 5 has a dovetail groove 11 formed to slide with the dovetail tenon 10. Both ends of the dovetail groove 11 extend laterally through the left and right sides of the swing frame 5. The saw blade frame 9 slides with the bottom of the swing frame 5 through the interaction between the dovetail groove 11 and the dovetail tenon 10. A pull rod 12 is arranged laterally on the outer side of the saw blade frame 9. One end of the pull rod 12 is driven and connected to the saw blade frame 9. The saw blade 7 is driven and connected to the pull rod 12 through the saw blade frame 9. A rotating wheel 13 is rotatably arranged below the swing frame 5. The rotating wheel 13 is located laterally on the inner side of the workbench 1. One end of the drive motor 6 is driven and connected to the rotating wheel 13. The other end of the pull rod 12 is driven and connected to the rotating wheel 13. The saw blade frame 9 is driven and connected to the rotating wheel 13 through the pull rod 12. The drive motor 6 drives the drive wheel 13 to rotate below the swing frame 5, thereby driving the pull rod 12 and the saw blade 7 to move obliquely back and forth at the bottom of the swing frame 5. In this embodiment, since the dovetail groove 11 and the dovetail tenon 10 are both narrow at the root and wide at the end, forming a large head shape, after the dovetail tenon 10 and the dovetail groove 11 cooperate with each other, a tension will be generated between the dovetail tenon 10 and the dovetail groove 11. This tension allows the saw blade frame 9 to be connected to the bottom of the swing frame 5. When the drive motor 6 drives the drive wheel 13 to rotate below the swing frame 5, the drive wheel 13 will synchronously drive the pull rod 12, the saw blade frame 9, and the saw blade 7 to move obliquely back and forth at the bottom of the swing frame 5. This tension can support the saw blade frame 9 and the saw blade 7 to slide at the bottom of the swing frame 5, so that the saw teeth on the saw blade 7 can continuously cut the carton 2, thereby realizing the cutting of the carton 2 located at the top of the workbench 1, effectively improving the practicality of this embodiment.

[0026] A cylinder frame 14 is provided on the side of the workbench 1, and a second cylinder 15 is vertically provided at the bottom of the cylinder frame 14. The second cylinder 15 passes through the cylinder frame 14 and is driven to the other end of the swing frame 5. The second cylinder 15 drives the swing frame 5 to deflect at an angle at the top of the workbench 1. In this embodiment, the end driven by the second cylinder 15 is the movable end of the swing frame 5. So when the saw blade 7 and the pressure plate 4 are in the initial position, the second cylinder 15 is in the extended state. After the carton 2 is in the limit position, the operator will control the second cylinder 15 to start to retract gradually. At this time, the swing frame 5 will drive the saw blade frame 9 and the saw blade 7 to change from a left-low-right-high state to a left-high-right-low state under the drive of the second cylinder 15. When the second cylinder 15 continues to retract, the swing frame 5 will drive the saw blade frame 9 and the saw blade 7 to swing downwards under the drive of the second cylinder 15 until the saw teeth on the saw blade 7 contact each other at the right edge of the top of the carton 2. Through the cooperation between the above structures, the practicality of this embodiment is effectively improved.

[0027] Each side bottom of the L-shaped support frame 3 has a limiting groove 16 formed, and the limiting groove 16 extends horizontally through the L-shaped support frame 3. The carton 2 is horizontally located in the limiting groove 16, and both sides of the carton 2 are in contact with the two sides of the limiting groove 16. The workbench 1 has multiple placement boards 17 formed on it to support the carton 2. The placement boards 17 are horizontally located on the front and rear sides of the workbench 1, and the top of each placement board 17 is flush with the top of the workbench 1. In this embodiment, when the worker needs to cut the carton 2, he only needs to place the carton 2 horizontally in the limiting groove 16, so that the two sides of the limiting groove 16 are in contact with the two sides of the carton 2. Then, the worker pushes the carton 2 to move horizontally in the limiting groove 16 until the carton 2 is simultaneously located in two limiting grooves 16. By limiting the two sides of the carton 2 simultaneously through the two limiting grooves 16, the carton 2 will not swing arbitrarily, which further improves the stability of this embodiment.

[0028] The above embodiments are merely explanations of this application and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
