Description

Technical Field

[0001] This application relates to the field of corrugated cardboard box production, and in particular to a cutting device for corrugated cardboard box production. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to create corrugated boxes. Corrugated boxes are the most widely used packaging product, consistently ranking first in usage among all packaging products. This includes calcium-plastic corrugated boxes. For over half a century, corrugated boxes have gradually replaced wooden crates and other transport packaging containers due to their superior performance and good processing properties, becoming the mainstay of transport packaging.

[0003] For example, China has disclosed a cutting device for corrugated cardboard box production in its patent literature (Publication No.: CN221775386U), but it still has the following defects: While the aforementioned corrugated cardboard box cutting device achieves the effect of compressing the airbag as the load-bearing plate descends, and the airbag delivers internal gas through the air pipe to the interior of the pressure chamber to drive the air pressure rod and gravity plate to move and fix the corrugated cardboard, making it highly practical, it still has some drawbacks. Due to the inconsistent height of the output port at the front end of the corrugated cardboard box cutting process, and the fact that cutting can easily damage the conveyor belt, manual operation is required. However, the weight of the corrugated cardboard boxes can make operation difficult. Utility Model Content

[0004] To address the issues of inconsistent output heights in the front-end steps of corrugated carton cutting, and the potential damage to the conveyor belt caused by cutting, which necessitates operator intervention, but the weight of the corrugated carton can make operation difficult, this application provides a cutting device for corrugated carton production.

[0005] The cutting device for corrugated cardboard box production provided in this application adopts the following technical solution: A cutting device for corrugated cardboard box production includes an operating frame. A vertically movable cutting blade is arranged inside the operating frame. An abutment plate is arranged vertically below the cutting blade. A groove is formed at the top of the abutment plate. Connecting plates are installed at both ends of the abutment plate. Auxiliary rollers are hinged at equal intervals at the top of the connecting plates. A transmission component for driving the connecting plates to move up and down is arranged below the connecting plates.

[0006] By adopting the above technical solution, the height of the contact plate can be adjusted through the transmission component during use to match the front-end processing equipment, and the corrugated carton can move on the auxiliary roller, saving manpower and improving practicality.

[0007] Preferably, a connecting plate is installed at the top of the cutting blade, movable cavities are provided on both sides of the cutting blade, and the connecting plate is installed between the two movable cavities. The top of the movable cavity is connected to the bottom of the mounting plate. A cylinder is installed at the top of the operating frame, and the top of the mounting plate is connected to the output end of the cylinder.

[0008] By adopting the above technical solution, during the operation, the mounting plate is driven by a cylinder to output the work, thereby making the cutting blade vertically downward, thus completing the cutting of the corrugated cardboard box.

[0009] Preferably, connecting springs are installed at equal intervals at the top of the inner cavity of the movable cavity, and the bottom end of the connecting spring is connected to the top end of the movable block. The movable block is vertically and movably connected to the bottom end of the movable cavity, and a balloon block is installed at the bottom end of the movable block.

[0010] By adopting the above technical solution, during use, the cylinder drives the mounting plate to perform output operations, causing the balloon block to abut against the top of the corrugated cardboard, thereby improving stability during the corrugated cardboard cutting process.

[0011] Preferably, sliding sleeves are installed on both outer walls of the mounting plate, and the sliding sleeves are vertically and movably connected to the outer wall of the operating frame.

[0012] By adopting the above technical solution, the vertical movement of the mounting plate allows the sliding sleeve to move vertically on the outer wall of the operating frame, thereby improving the stability of the mounting plate.

[0013] Preferably, the transmission assembly includes a guide groove, a guide slider, a connecting frame, and a support arm. The bottom of the operating frame is equipped with a guide groove, and a guide slider is slidably connected inside the guide groove. A connecting frame is installed at the top of the guide slider. The top of the connecting frame is hinged to one end of the support arm via a rotating shaft. The top of the support arm is hinged to the bottom of the contact plate. A transmission screw sleeve is installed through the interior of each guide slider, and a connecting screw is meshed through the inner wall of the transmission screw sleeve. The teeth on the outer walls of the connecting screws on both sides have opposite structures. A linkage rod connects the connecting screws on both sides.

[0014] By adopting the above technical solution, the guide slider moves left and right inside the guide groove, thereby driving the connecting frame to move synchronously, thus changing the tilt angle of the support arm, and then changing the height of the contact plate through the support arm. Furthermore, through the screw transmission structure composed of the connecting screw and the transmission screw sleeve, the connecting screws on both sides rotate, thereby driving the guide slider to move relative to each other or in opposite directions.

[0015] Preferably, one end of one of the connecting screws is connected to one end of a transmission knob, and the transmission knob is rotatably connected to the outer wall of the operating frame.

[0016] By adopting the above technical solution, the connecting screw can be driven to rotate forward or backward by the set transmission knob.

[0017] Preferably, each of the connecting plates is equipped with a stabilizing frame at its bottom end, and each of the stabilizing frames is equipped with a guide sleeve rod at its bottom center. The guide sleeve rod is vertically and movably connected to the inside of the top end of the guide sleeve, and the guide sleeve is symmetrically installed on the outer walls of both ends of the guide groove.

[0018] By adopting the above technical solution and setting up a stabilizing frame, the support stability of the connecting plate is improved, and the vertical movement stability of the contact plate and the connecting plate is improved by using guide sleeves and guide rods.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. During use, this utility model enables the contact plate and the connecting plate to move vertically up and down, thereby allowing the contact plate and the connecting plate to quickly adapt to front-end processing equipment with different output heights. In addition, during use, the corrugated cardboard is assisted in the transfer of corrugated cardboard through the auxiliary roller, which improves practicality and convenience and effectively improves processing efficiency. 2. In the process of cutting corrugated cardboard with a cutting blade, when the cutting blade moves vertically, the spherical block will first come into contact with the front and rear ends of the corrugated cardboard cutting area, ensuring the stability of the corrugated cardboard cutting area, effectively improving the cutting effect, avoiding the situation of the corrugated cardboard shifting, and improving the practicality of the device.

[0022] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0023] This application discloses a cutting device for corrugated cardboard box production.

[0024] Reference Figures 1-3 A cutting device for corrugated cardboard box production includes an operating frame 1. A cylinder 2 is fixedly connected to the top of the operating frame 1, and the output end of the cylinder 2 passes through the top of the operating frame 1 and is fixedly connected to the top of the mounting plate 3. Sliding sleeves 10 are fixedly connected to both outer walls of the mounting plate 3, and the sliding sleeves 10 are vertically movably connected to both outer walls of the operating frame 1. A movable cavity 6 is symmetrically fixedly connected to the bottom of the mounting plate 3, and connecting springs 7 are fixedly fixedly connected at equal intervals to the top of the interior of the movable cavity 6. The bottom of the connecting springs 7 is fixedly connected to the top of the movable block 8, and the top of the movable block 8 is vertically movably connected to the bottom of the movable cavity 6. The bottom of the movable block 8 is fixedly connected to the top of the inflatable balloon block 9. A connecting plate 5 is fixedly connected between the movable cavities 6, and a cutting blade 4 for cutting corrugated cardboard is vertically fixedly connected to the bottom of the connecting plate 5. The pressure of the cylinder 2 is 8-10 MPa, and the cutting blade 4 is made of high carbon steel.

[0025] During use, when the cutting blade 4 corresponds to the area of ​​the corrugated cardboard to be cut, the cylinder 2 drives the mounting plate 3 to move vertically. First, the ball block 9 abuts against the front and rear ends of the corrugated cardboard to be cut, and pushes the movable block 8 to move vertically upward to abut against the connecting spring 7. This drives the potential energy generated by the connecting spring 7, thereby making the ball block 9 abut more effectively, improving the stability of the corrugated cardboard to be cut during the cutting process, and ensuring the accuracy of the cut.

[0026] Reference Figure 1 , Figure 5 and Figure 6The bottom of the operating frame 1 is fixedly connected to a transmission assembly, which includes a guide groove 15, a guide slider 16, a connecting frame 21, and a support arm 22. The bottom of the operating frame 1 is fixedly connected to the guide groove 15, and the guide slider 16 is slidably connected to the inside of the guide groove 15. The top of the guide slider 16 is fixedly connected to the connecting frame 21, and a support arm 22 is provided between the top of the connecting frame 21 and the bottom of the contact plate 11. The top of the support arm 22 is hinged to the bottom of the contact plate 11 via a pivot. Next, the bottom end of the support arm 22 is hinged to the top of the connecting frame 21 via a rotating shaft. The inside of the guide slider 16 is fixedly connected with a transmission screw sleeve 17, and the inner side wall of the transmission screw sleeve 17 is engaged with a connecting screw 18. The teeth on the outer side walls of the two connecting screws 18 are arranged in opposite structures. A linkage rod 19 is fixedly connected between the two connecting screws 18. One end of one of the connecting screws 18 is fixedly connected to one end of the transmission knob 20. The transmission knob 20 is rotatably connected to the outer side wall of the operating frame 1.

[0027] During use, the guide slider 16 moves relative to each other inside the guide groove 15, thereby synchronously driving the connecting frame 21 to move synchronously, thus changing the tilt angle of the support arm 22. In this way, the moving support arm 22 pushes the contact plate 11 and the connecting plate 13 to move vertically, so that the contact plate 11 and the connecting plate 13 can be adapted to front-end processing equipment with different output heights, improving the practicality of the device. The guide slider 16 is driven to move relative to each other by rotating the forward or reverse transmission knob 20, which in turn drives the connecting screws 18 on both sides to rotate through the linkage rod 19. Since the teeth on the outer walls of the connecting screws 18 on both sides are set with opposite structures, the guide slider 16 moves relative to each other inside the guide groove 15.

[0028] Reference Figure 1 and Figure 4 The top of the contact plate 11 has a groove 12 in the area perpendicular to the cutting blade 4. The front and rear ends of the contact plate 11 are fixedly connected to the connecting plate 13. The top of the connecting plate 13 is rotatably connected to the auxiliary roller 14 at equal intervals. The bottom ends of the connecting plates 13 are fixedly connected to the stabilizing frame 23. The bottom end of the stabilizing frame 23 is fixedly connected to the middle of the bottom end of the stabilizing frame 23. The bottom end of the stabilizing frame 23 is vertically movably connected to the top end of the guide sleeve 25. The guide sleeve 25 is symmetrically fixedly connected to the front and rear ends of the guide groove 15. The auxiliary roller 14 is made of wear-resistant rubber material and has a patterned structure on its outer surface.

[0029] When the contact plate 11 moves vertically, it drives the connecting plate 13 to move vertically. The auxiliary roller 14 hinged inside the connecting plate 13 assists in the transfer of the corrugated cardboard to be cut, avoiding the problem of difficulty in operation due to the large weight of the corrugated cardboard to be cut. During the vertical movement of the contact plate 11 and the connecting plate 13, the stabilizing frame 23 and the guide sleeve 24 provide auxiliary guidance through the guide sleeve 25. This makes the vertical movement of the contact plate 11 and the connecting plate 13 more stable, and at the same time guides the contact plate 11 and the connecting plate 13.

[0030] The implementation principle of a cutting device for corrugated cardboard box production according to an embodiment of this application is as follows: First, after the corrugated carton is produced, the device is installed in the area where the segmented cutting is required according to the standard. By turning the forward or reverse transmission knob 20, the connecting screws 18 on both sides are driven to rotate through the linkage rod 19. Since the outer side teeth of the connecting screws 18 on both sides are set with opposite structures, the guide slider 16 moves relative to each other inside the guide groove 15. Secondly, by moving relative to each other inside the guide slide 15, the guide slider 16 drives the connecting frame 21 to move synchronously, thereby changing the tilt angle of the support arm 22. In this way, the moving support arm 22 pushes the contact plate 11 and the connecting plate 13 to move vertically up and down, so that the contact plate 11 and the connecting plate 13 can be adapted to front-end processing equipment with different output heights. Afterwards, when the contact plate 11 moves vertically, it drives the connecting plate 13 to move vertically, and the auxiliary roller 14 hinged inside the connecting plate 13 assists in the transfer of the corrugated cardboard to be cut. Finally, when the cutting blade 4 corresponds to the area of ​​the corrugated cardboard to be cut, the cylinder 2 drives the mounting plate 3 to move vertically up and down. First, the ball block 9 abuts against the front and rear ends of the area of ​​the corrugated cardboard to be cut, and pushes the movable block 8 to move vertically upward to abut against the connecting spring 7. This drives the potential energy generated by the connecting spring 7, thereby making the ball block 9 abut more effectively. The cutting blade 4 then completes the cutting of the corrugated cardboard. In this way, the cutting device for corrugated cardboard production is completed.

[0031] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
