Description

Technical Field

[0001] This invention relates to the field of cardboard processing equipment, and more specifically to a cutting mechanism for rapidly cutting cardboard. Background Technology

[0002] To process corrugated cardboard into cartons, it needs to be cut using a die to remove excess material, facilitating subsequent carton production. Previously, multiple blades were mounted on a flat plate, which was pressed down to cut away the excess. However, this method couldn't achieve continuous cutting, making it relatively slow. Modern cardboard cutting uses rollers, where blades are mounted on rollers, and the rotation of the rollers and the movement of the cardboard achieve continuous cutting. This method is more efficient. However, when changing cartons, the rollers need to be replaced promptly. Since roller installation is more difficult, it takes longer and involves greater labor intensity for workers, reducing efficiency. Furthermore, storage space is required for rollers of other carton sizes. Summary of the Invention

[0020] The invention will now be further described in conjunction with the accompanying drawings. like Figure 1-7 As shown, a rapid cardboard cutting mechanism includes a feeding mechanism 1, a conveying mechanism 2, a pressing mechanism 3, and a cardboard cutting module 4. The feeding mechanism 1 is connected to the conveying mechanism 2 at one end. (The feeding mechanism 1 includes a pallet and a feeding wheel. A vertical rod is fixed to the ground by bolts, passing through the pallet. The pallet rises and falls on the vertical rod. A hydraulic cylinder is fixed between the ground and the bottom of the pallet by bolts, and the lifting and lowering of the pallet is achieved by the hydraulic cylinder. The cardboard is placed on the pallet. A motor-driven mechanism is installed at the top of the vertical rod.) The feeding wheel is movable. When the topmost cardboard contacts the feeding wheel, the bottom of the cardboard is flush with the conveying mechanism 2. The feeding wheel transports the cardboard to the conveying mechanism 2. Multiple sets of pressing mechanisms 3 are installed side by side on the conveying mechanism 2 through bearings and bearing seats to press the cardboard. When the pressing mechanism 3 presses the cardboard, it is transported through the pressing mechanism 3. A cardboard cutting module 4 is set between two sets of pressing mechanisms 3. The cardboard cutting module 4 cuts the two sides of the cardboard, which facilitates the subsequent slotting of the two ends of the cardboard. The conveying mechanism 2 is a conveying plate with a smooth coating on the top to facilitate the movement of the cardboard on the plate. The cardboard is placed on the plate for conveying. Limiting side plates 26 are provided on the conveying plate to limit the left and right sides of the cardboard. The limiting side plates 26 abut against the left and right sides of the cardboard to limit its movement. A first adjusting component 30 is provided between the limiting side plates 26 and the conveying plate to adjust the distance between the two limiting side plates 26. During processing, the width of the cardboard may vary, so the distance between the two limiting side plates 26 needs to be adjusted. The pressing mechanism 3 consists of pressing rollers. Each pressing roller is mounted on the conveying plate via bearings and bearing seats. The pressing rollers are driven by a motor, thus enabling their rotation. The pressing rollers are located above the conveying plate, and the paperboard is conveyed through the pressing rollers and the conveying plate. The features are as follows: Two cardboard cutting modules 4 are arranged opposite each other, located on the left and right sides of the conveying mechanism 2; each cardboard cutting module 4 includes a rotating shaft 5, an adjustable cutting mounting base 6, and a cutting blade 14. Second height adjustment components 15 (i.e., lifting rods, lifting sleeves, and lead screws) are provided on both sides of the conveying mechanism 2. Two vertically arranged lifting rods are fixed to the top of the left and right sides of the conveying mechanism 2 by welding. Lifting sleeves that move up and down on the lifting rods are fitted onto the lifting rods. A lifting block is fixed between the two lifting sleeves on the same side by welding. A motor is fixed to the conveying mechanism 2 at the bottom of the lifting block by welding. A lead screw is fixed to the output shaft of the motor by welding. The lead screw passes through the lifting seat and is threadedly engaged with the lifting seat. The rotation of the lead screw realizes the lifting of the seat. The second adjustment assembly 15 has a rotating shaft 5 mounted on top of it via bearings and bearing seats (the bearings and bearing seats at both ends of the rotating shaft 5 are mounted on the lifting seat and adjusted according to the length of the cardboard). The right end of the rotating shaft 5 is welded to the output shaft of the stepper motor, and the rotating shaft 5 is driven by the stepper motor to rotate. The rotating shaft 5 is a multi-faceted prism, and an adjustable cutting mounting seat 6 that moves on the rotating shaft 5 is fitted on it. The rotating shaft 5 is a prism, which allows the rotating shaft 5 and the adjustable cutting mounting seat 6 to rotate synchronously. The adjustable cutting mounting seat 6 is fitted with a sliding ring 16, and the adjustable cutting mounting seat 6 can move left and right on the rotating shaft 5. This allows for left and right adjustment according to the length of the cardboard that needs to be cut. During operation, the position of the adjustable cutting mounting seat 6 is adjusted according to the width of the cardboard, so that the adjustable cutting mounting seat 6 can cut the cardboard on both sides.The sliding ring 16 is coaxially mounted on the adjustable cutting mounting base 6 via a bracket. The two ends of the bracket are fixed to the sliding ring 16 and the adjustable cutting mounting base 6 by welding. Four sliding grooves 17 are installed between the adjustable cutting mounting base 6 and the sliding ring 16. The two ends of the sliding grooves 17 are slidably fitted onto the adjustable cutting mounting base 6 and the sliding ring 16. Locking components are provided at both ends of the sliding grooves 17 and on both the adjustable cutting mounting base 6 and the sliding ring 16. The two ends of the sliding grooves 17 have grooves that engage with the adjustable cutting mounting base 6 and the sliding ring 16, thus enabling the sliding of the sliding grooves 17. Locking components are provided at both ends of the sliding grooves 17. The component is a locking bolt. The locking bolt passes through the groove and abuts against the adjustable cutting mounting base 6 and the sliding ring 16 to lock the sliding groove 17. This allows adjustment of the angle between the four sliding grooves 17, which is convenient for slotting the carton according to its size (generally, the carton is rectangular or square, so the position of the folds varies depending on the carton's needs. The ends of each horizontal fold of the cardboard need to be trimmed to remove excess cardboard, thus forming grooves at both ends of the folds. This facilitates the subsequent formation of the carton body. The position of the sliding groove 17 is adjusted according to the ratio between the folds, so that when the sliding groove 17 is rotated to the bottom, it is vertically aligned with the folds).A sliding block 18 is installed in each sliding groove 17, and a cutting seat 19 is provided outside the adjustable cutting mounting base 6. The sliding block 18 and the cutting seat 19 are connected by connecting rods. The two ends of multiple connecting rods are fixed to the sliding block 18 and the cutting seat 19 by welding. When the sliding block moves, the cutting seat 19 moves accordingly. When the cardboard is relatively short, the cutting seat 19 is close to the sliding ring 16. When the cardboard is relatively long, the cutting seat 19 is away from the sliding ring 16 (always ensuring that the cutting seat 19 contacts the same position with each piece of cardboard, thus achieving fixed-point cutting. It is necessary to ensure that the rotation circumference of the cutting seat 19 is consistent with the length of the cardboard). Two oppositely arranged cutting blades 14 are installed on the cutting seat 19. When the cutting blades 14 press on the cardboard, they cut two slits in the cardboard. The cardboard between the slits is then removed to form a groove (for subsequent cardboard cutting). The mounting base 6 has clamping plates 22 installed on both sides. An adjusting rod 23 is hinged to each sliding block 18. A spring is fixed between the sliding block 18 and the outer side of the sliding groove 17 by welding. The spring pushes the sliding block 18 towards the adjustable cutting mounting base 6. A swing rod 24 is hinged to the adjusting rod 23. The other end of the swing rod 24 is hinged to the inner side of the sliding groove 17. The hinge of the swing rod 24 and the adjusting rod 23 abuts against the inner side of the clamping plate 22 (a pulley is installed at the hinge of the swing rod 24 and the adjusting rod 23 by bolts. The pulley abuts against the inner side of the clamping plate 22 to avoid wear). A clamping assembly 25 is set between the two clamping plates 22. The clamping assembly 25 is used to adjust the distance between the clamping plates 22, thereby adjusting the distance between the cutting plate base and the rotating shaft 5. This can be used to cut cardboard of different sizes. At the same time, when cutting cardboard, adjacent cardboard pieces move closer to each other, so that the groove at the front end of the cardboard and the groove at the rear end of the next cardboard piece open together. Upward-blowing jet components 32 are provided on the bottom of both sides of the conveying mechanism 2. The jet components 32 are located on the conveying mechanism 2 behind the cardboard cutting module 4. The jet components 32 blow air upward. Since the cardboard between the two cuts is relatively narrow (the cardboard to be cut), the cardboard to be cut is blown upward when the wind blows. Guide rails 34 are provided on the upper left and right sides of the conveying mechanism 2. The cardboard to be cut swings upward and is conveyed backward and placed on the guide rails 34. The guide rails 34 change the cut cardboard strips from horizontal to vertical. A cutting component 36 is provided at the end of the guide rails 34. The cutting component 36 cuts the cardboard to be cut to form a groove.

[0021] The adjustable cutting mounting base 6 is a long sleeve 7, which is directly fitted onto the rotating shaft 5. The adjustable cutting mounting base 6 rotates together with the rotating shaft 5. A gantry frame 8 is set above the rotating shaft 5. The ends of the gantry frame 8 on the left and right sides are fastened to the top surface of the lifting seat by bolts. A slide rail 9 parallel to the rotation is fixed to the bottom of the gantry frame 8 by bolts. A slider 10 that slides on the bottom of the slide rail 9 is locked on the slide rail 9. A first cylinder 11 is set between the slider 10 and the gantry frame 8. The piston rod and cylinder body of the first cylinder 11 are fixed to the slider 10 and the gantry frame 8 by bolts respectively. The position of the slider 10 is adjusted by the extension and retraction of the first cylinder 11. A column is fixed to the bottom of each slider 10 by welding. The bottom of the column is connected by bearings. The adjustable cutting mounting base 6 is connected to the column so that the column does not affect the rotation of the adjustable cutting mounting base 6, and the adjustable cutting mounting base 6 rotates and moves left and right together with the column. Columns are installed at both ends of the adjustable cutting mounting base 6. A sliding plate 12 is set on the outside of the two columns. A motor is installed on the outside of the columns by bolts. A lead screw passing through the sliding plate 12 is installed on the output shaft of the motor by welding. The lead screw and the sliding plate 12 are threaded together. A horizontally arranged guide rod 13 is fixed at the upper and lower ends of the plate by welding. The guide rod 13 passes through the column and is connected to the outer side of the clamping plate 22 by welding. The forward and reverse rotation of the motor makes the clamping plate 22 move closer or further away, thus adjusting the distance between the cutting base 19 and the rotating shaft 5.

[0022] Each cutting seat 19 has two parallel blade holders 20 mounted on its bottom. A cutting blade 14 is mounted on each blade holder 20. The cutting seat 19 and blade holder 20 are slidably connected (a convex track is mounted on the bottom of the cutting seat 19, and a concave groove is formed on the back of the blade holder 20 to engage with the track, allowing the blade holder 20 to move on the cutting seat 19; adjusting the distance between the two blade holders 20 adjusts the width of the cut cardboard). A rotating rod 21 is provided between the cutting seat 19 and the blade holder 20. Rod 21 passes through cutting seat 19. Rotating rod 21 is connected to cutting seat 19 through bearing. Rotating rod 21 can rotate. One end of rotating rod 21 extending out of cutting seat 19 has a thread. A stepper motor is fixed to the other end of rotating rod 21 by welding. A nut is fitted on the bolt section of rotating rod 21. A connecting rod is hinged between the outer wall of the nut and the cutter holder 20. The nut is raised or lowered by rotating rod 21. When the nut is raised or lowered, the corresponding cutter holders 20 move closer or further apart.

[0023] The jet assembly 32 is the jet nozzle 33, which is connected to the air pump via a pipe. The jet nozzle 33 is installed on the top surface near the left and right sides of the conveying mechanism 2, flush with the top surface of the conveying mechanism 2. The jet nozzle 33 is vertically upward and sprays air upward, blowing the cardboard upward. Since the cardboard to be cut is relatively narrow, it tilts upward under the action of the air. A guide rail 34 is provided above and behind the jet nozzle 33. The guide rail 34 presses against the conveying mechanism 2. The air blowing action swings the cardboard to be cut upward and conveys it backward, so that the cardboard to be cut rests on the guide rail 34. As the cardboard moves backward, the cardboard to be cut slowly swings upward to 90°. A limiting pressure plate 35 is set above the conveyor plate, pressing the cardboard. The outer edge of the limiting pressure plate 35 is flush with the inner side of the cutting blade 14. The guide rail 34 is an inclined rail with an inclined surface on the inner side. The distance between the end of the guide rail 34 and the limiting pressure plate 35 is the thickness of the cardboard. A cutting assembly 36 is set at the end of the guide rail 34 and the limiting plate. The cutting assembly 36 consists of two sets of cutting wheels 37 arranged opposite each other. The bottom of the cutting wheels 37 contacts the top of the cardboard, thus cutting the cardboard to be cut to form a groove.

[0024] Two sets of U-shaped frames 38 are arranged side by side above the conveying mechanism 2. The bottom of the U-shaped frames 38 is fastened to the left and right sides of the conveying mechanism 2 by bolts. Long strip-shaped adjustment grooves 39 are opened on the U-shaped frames 38 (the adjustment grooves 39 are arranged horizontally). Adjustment blocks 40 are installed in the adjustment grooves 39 and slide within them. The adjustment blocks 40 move left and right within the adjustment grooves 39. A cylinder is installed between the adjustment blocks 40 and the U-shaped frames 38 (the piston rod and cylinder body of the cylinder are respectively bolted to the adjustment blocks 40 and the U-shaped frames 38). The position of the adjusting block 40 is adjusted by extending and retracting the cylinder. A vertically arranged connecting rod is installed on the adjusting block 40 by welding, and the connecting rod is connected to the guide rail 34 and the limiting pressure plate 35 by welding. The position of the guide rail 34 and the limiting pressure plate 35 is adjusted in this way. A motor is fixed above the end of the guide rail 34 and the limiting pressure plate 35 by welding. A cutting wheel 37 is fixed on the output shaft of the motor by welding. The cutting wheel 37 cuts the strip and cuts the cardboard.

[0025] A rotating shaft 41 is mounted above the end of the conveying mechanism 2 via bearings and bearing seats. Two adjusting cylinders 42 are fitted on the rotating shaft 41. The adjusting cylinders 42 can move left and right. A needle roller 43 is mounted on the adjusting cylinder 42 by welding. A notch 44 is opened on the conveying mechanism 2 to allow the needle roller 43 to move. A locking assembly is provided on the adjusting cylinder 42. The locking assembly is a locking bolt. The locking bolt passes through the adjusting cylinder 42 and abuts against the rotating shaft 41 to achieve locking. The rotating shaft 41 is a multi-faceted prism. The adjusting cylinder 42 rotates synchronously with the rotating shaft 41. Both ends of the rotating shaft 41 are mounted on the conveying mechanism 2 via bearings and bearing seats. When it is necessary to punch needle holes on the cardboard, the adjusting cylinder 42 is moved above the cardboard and locked by the locking assembly. In this way, rows of needle holes are punched when the cardboard moves.

[0026] The inner side of the limiting side plate 26 is bolted with rollers 27, which contact the side of the cardboard in a rolling action. Adjusting seats 28 are bolted to the left and right sides of the conveying mechanism 2. An outwardly extending longitudinal rod 29 is welded to the outer side of the limiting side plate 26. The longitudinal rod 29 slides through the adjusting seat 28. A first adjusting component 30 is provided on the limiting side plate 26 and the adjusting seat 28. The first adjusting component 30 is a cylinder. The cylinder body and piston rod of the first adjusting component 30 are bolted to the adjusting seat 28 and the limiting side plate 26, respectively. The position of the limiting side plate 26 is adjusted by the extension and retraction of the first adjusting component 30.
