Description

Technical Field

[0001] This invention relates to the field of corrugated paper cutting equipment, and in particular to a corrugated paper cutting equipment that facilitates neat stacking. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper formed by corrugating rollers. It is generally divided into two categories: single-wall corrugated paperboard and double-wall corrugated paperboard. In the processing and production of corrugated paper, it is often necessary to cut the corrugated paper. In the existing technology, CNC band saws are often used to cut the corrugated paper.

[0003] Currently, Chinese patent CN216266538U, published on November 3, 2021, discloses a plate band saw, including a box body. A movable door is hinged to the front of the box body. A motor is fixedly installed on the rear side of the inner wall of the box body. A motor shaft is fixedly connected to the output end of the motor. A support block is rotatably connected to the end of the motor shaft away from the motor through a bearing. The bottom of the support block is fixedly connected to the inner wall of the box body. A drive wheel is fixedly sleeved on the surface of the motor shaft. A saw blade is meshed on the surface of the drive wheel. A driven wheel is meshed on the inner wall of the saw blade away from the drive wheel. A rotating shaft is fixedly inserted into the middle of the driven wheel. A support frame is rotatably connected to the surface of the rotating shaft through a bearing. A threaded column is fixedly connected to the top surface of the support frame.

[0004] In the production of corrugated paper cat scratching boards, the corrugated paper is often cut using a band saw. The high-speed moving saw blade can cut the corrugated paper into board-shaped cat scratching boards. The cut corrugated paperboards need to be removed piece by piece by the operator, and multiple pieces of corrugated paperboards need to be collected manually. This makes the corrugated paperboard processing process relatively labor-intensive. Summary of the Invention

[0005] The purpose of this invention is to provide a corrugated cardboard cutting device that facilitates neat stacking of the cut corrugated cardboard.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a corrugated paper cutting device for easy and neat stacking, comprising a band saw, the band saw comprising a machine body, a worktable located on the machine body, a saw blade located on the machine body and passing through the worktable, and a drive assembly located on one side of the band saw for feeding the corrugated paper to be cut toward the band saw. A feeding cylinder is provided on the worktable on the side away from the drive assembly from the saw blade. The piston rod end of the feeding cylinder is provided with a push plate for pushing the cut corrugated paper. A slide rail is provided on the side of the worktable away from the feeding cylinder for the corrugated paper pushed by the push plate to fall. A connecting plate is provided on the lower side of the slide rail. The connecting plate is provided with multiple spaced first support arms for supporting the corrugated paper. A base is provided on the ground on one side of the band saw. A column is provided on the upper side of the base. Both the upper and lower ends of the column are rotatably connected to drive sprockets. An output shaft is provided on the column and connected to any... A drive motor is connected to a drive sprocket. A drive chain is provided between two drive sprockets. A fixed plate is fixed on the drive chain. Multiple second support arms are provided on the fixed plate at intervals and for passing through the gaps between multiple first support arms. A limiting frame for the fixed plate to be embedded is provided on the drive chain. Guide sleeves are provided at both ends of the limiting frame. Guide posts are provided at both ends of the base and for passing through the two guide sleeves respectively. An mounting arm is provided at the upper end of the post. A first connecting rod is provided on one side of the mounting arm. A fixed motor is provided at the lower end of the first connecting rod. A swing arm is connected to the output shaft of the fixed motor. Multiple third support arms are provided at the end of the swing arm away from the fixed motor and for passing through the gaps between multiple second support arms. A second connecting rod is also provided on one side of the mounting arm. A baffle is provided at the lower end of the second connecting rod for abutting against the corrugated cardboard on the third support arm and for the corrugated cardboard to fall neatly.

[0007] A further provision of the present invention is that a storage rack for storing corrugated cardboard is provided on the ground below the baffle. The storage rack includes a base plate, a side plate located on the upper side of the base plate, and multiple partition plates located on the side wall of the side plate and evenly spaced on the side wall of the side plate. A gap is left between the top of the side plate and the baffle for the swing arm to pass through.

[0008] A further feature of the present invention is that self-locking casters are provided at the four corners of the lower surface of the base plate.

[0009] A further feature of the present invention is that a rubber positioning strip for adhering to the outer wall of the partition plate is provided on the lower side of the baffle.

[0010] A further configuration of the present invention is as follows: the baffle is L-shaped, the L-shape formed by the third support arm and the swing arm is used in conjunction with the baffle, and the angle of the baffle is located on the arc trajectory formed by the rotation of the end of the swing arm.

[0011] A further feature of the present invention is that the connecting plate is L-shaped.

[0012] A further feature of the present invention is that: limit plates are provided on both sides of the slide, and an arc-shaped guide plate is provided at the end of the limit plate located away from the saw blade.

[0013] A further configuration of the present invention is as follows: the driving assembly includes a base, a movable frame located on the base, a first rodless cylinder connected to both sides of the base and used to connect the movable frame, a movable plate disposed on the upper side of the movable frame, a second rodless cylinder connected to both sides of the movable frame and used to connect the two ends of the movable plate respectively, a fixed clamping block disposed at one end of the movable plate, a movable clamping block disposed at the other end of the movable plate, and a clamping cylinder disposed on the movable plate and used to push the movable clamping block.

[0014] A further feature of the present invention is that both the fixed clamping block and the movable clamping block are provided with serrated grooves.

[0015] In summary, the present invention has the following beneficial effects:

[0016] 1. When the corrugated paper is cut into corrugated cardboard by the saw blade in the band saw under the drive of the drive assembly, the corrugated cardboard can fall onto the worktable. At this time, the feeding cylinder can push the corrugated cardboard on the worktable through the push plate, so that the corrugated cardboard falls onto the slide and slides along the slide onto the upper side of multiple first support arms.

[0017] The drive motor drives the drive sprocket to rotate, which in turn drives the drive chain. The drive chain then moves multiple second support arms on the fixed plate, allowing the second support arms to pass through the gaps between multiple first support arms. At this point, the corrugated cardboard on the first support arm can fall onto the second support arm. Meanwhile, since the fixed plate is embedded in the limiting frame, and the guide sleeves at both ends of the limiting frame are fitted onto the guide posts, the multiple second support arms can always be kept on a horizontal plane, which is conducive to the stable movement of the corrugated cardboard.

[0018] When the second support arm passes the third support arm, the corrugated cardboard on the second support arm falls onto the third support arm. Then, the fixed motor drives the swing arm and the third support arm to swing toward the baffle. The baffle then comes into contact with the corrugated cardboard on the third support arm, and the corrugated cardboard is scraped off the third support arm. As one piece of corrugated cardboard after another is scraped off, multiple pieces of corrugated cardboard can be neatly stacked.

[0019] 2. After the corrugated cardboard is scraped off by the baffle, the cardboard pieces can be neatly stacked on the top of the base plate, which is limited by the side panels and partitions, using the storage rack on the ground below the baffle. By moving the storage rack, the positions of the partitions of different cavities can be aligned with the positions of the baffle, and finally the corrugated cardboard can be neatly stored in the storage rack.

[0020] 3. When it is necessary to move the storage rack, the self-locking casters on the underside of the base can be used to move the storage rack relatively easily;

[0021] 4. The rubber positioning strip on the lower side of the baffle can be used to adhere to the outer wall of the partition plate, thereby positioning the partition plate and the baffle plate in the same vertical plane. This will help the corrugated cardboard to fall accurately into the cavity where the partition plate is located.

[0022] Because the rubber positioning strip is made of soft rubber, it can bend when the swing arm passes over it, and then return to its original position after the swing arm has passed over it.

[0023] 5. The baffle is L-shaped, and the L-shaped structure formed by the third support arm and the swing arm works in conjunction with the baffle. At the same time, the folding position of the baffle is located on the arc trajectory formed by the rotation of the end of the swing arm. When the baffle needs to scrape off the corrugated cardboard on the third support arm, the two adjacent sides of the corrugated cardboard can be attached to the baffle. At this time, the position of the corrugated cardboard can be adjusted by the baffle. After the position of multiple corrugated cardboards is adjusted by the baffle, the position can be unified, which will ultimately facilitate the neat falling of multiple corrugated cardboards.

[0024] 6. By using the L-shaped connecting plate, the corrugated cardboard falling onto the first support arm can be limited, preventing the corrugated cardboard from slipping off the first support arm;

[0025] 7. The limiting plates on both sides of the slide can prevent the corrugated cardboard from sliding off the sides of the slide; at the same time, the arc-shaped guide plate at the end of the limiting plate on the side away from the saw blade can guide the corrugated cardboard into the slide, which is conducive to the smooth entry of the corrugated cardboard into the slide.

[0026] 8. When the drive assembly moves the corrugated paper, the clamping cylinder pushes the movable clamping block to clamp the corrugated paper onto the fixed clamping block. Then, the second rodless cylinder drives the movable plate, causing the movable plate to move in the Y-axis direction in the plane. At the same time, the first rodless cylinder drives the moving frame, causing the movable plate on the moving frame to move in the X-axis direction in the plane. Finally, the corrugated paper can be easily fed into the band saw for cutting corrugated cardboard piece by piece.

[0027] 9. The serrated grooves on both the fixed and movable clamping blocks facilitate stable clamping of the corrugated paper. Attached Figure Description

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] A corrugated paper cutting device that facilitates neat stacking, as described in the following reference. Figure 1This type of corrugated paper cutting equipment, which facilitates neat stacking, includes a band saw 1 and a drive assembly 2. The band saw 1 includes a body 11, a worktable 12 located on the body 11, and a saw blade 13 located on the body 11 and passing through the worktable 12. The internal structure of the band saw 1 is existing technology and will not be described in detail here. After the saw blade 13 cuts the corrugated paper, the corrugated cardboard can be cut off and then fall onto the worktable 12.

[0036] Reference Figure 1 , Figure 2 The drive assembly 2 is located on one side of the band saw 1 and is used to feed the corrugated paper to be cut toward the band saw 1. This drive assembly 2 includes a base 21, a moving frame 22, a first rodless cylinder 23, a movable plate 24, a second rodless cylinder 25, a fixed clamping block 26, a movable clamping block 27, and a clamping cylinder 28. The moving frame 22 is rectangular and located on the upper side of the base 21. There are two first rodless cylinders 23, which are fixed to the two sides of the base 21 by bolts. At the same time, the movable block inside the first rodless cylinder 23 is fixed to the side of the moving frame 22 by bolts. At this time, the first rodless cylinder 23 can drive the moving frame 22 to move in the X-axis direction in the plane.

[0037] Reference Figure 1 , Figure 2 The movable plate 24 is located on the upper side of the movable frame 22. Two rodless cylinders 25 are provided and are fixed to both sides of the movable frame 22 by bolts. The movable block inside the second rodless cylinder 25 is fixed to the end of the movable plate 24 by bolts. At the same time, the fixed clamping block 26 is fixed to one end of the movable plate 24 by bolts, and the movable clamping block 27 is located at the end of the movable plate 24 away from the fixed clamping block 26. One end of the clamping cylinder 28 is fixed to the movable clamping block 27 by bolts, and the other end is connected to the movable plate 24. Both the fixed clamping block 26 and the movable clamping block 27 are provided with serrated grooves 271. At this time, the movable clamping block 27 can be pushed by the clamping cylinder 28, thereby clamping the corrugated paper by the movable clamping block 27 and the fixed clamping block 26.

[0038] Reference Figure 3A feeding cylinder 121 is bolted to the workbench 12 on the side of the saw blade 13 away from the drive assembly 2. A push plate 122 is bolted to the piston rod end of the feeding cylinder 121. The push plate 122 can move along the upper surface of the workbench 12. At this time, the push plate 122 can be used to push the cut corrugated cardboard. A slide rail 123 is bolted to the side of the workbench 12 away from the feeding cylinder 121. The slide rail 123 allows the corrugated cardboard pushed by the push plate 122 to fall. Limiting plates 1231 are welded to both sides of the slide rail 123. At the same time, an arc-shaped guide plate 1232 is integrally provided at the end of the limiting plate 1231 on the side away from the saw blade 13. A connecting plate 124 is welded to the lower side of the slide rail 123. The connecting plate 124 is L-shaped. Multiple first support arms 1241 are bolted to the connecting plate 124. The multiple first support arms 1241 are spaced apart and their upper surfaces are used to support the corrugated cardboard.

[0039] Reference Figure 4 A base 3 is installed on the ground on one side of the band saw 1, and a column 31 is welded to the upper side of the base 3. Both the upper and lower ends of the column 31 are rotatably connected to drive sprockets 311 through bearings. A drive motor 312 with an output shaft connected to any one of the drive sprockets 311 is fixed to the column 31 by bolts. At the same time, a drive chain 313 is arranged between the two drive sprockets 311. At this time, the drive motor 312 can drive the drive chain 313 through the drive sprockets 311. A fixing plate 32 is fixed to the drive chain 313 by bolts. The fixing plate 32 is long and extends horizontally. Multiple second support arms 321 are welded to the fixing plate 32 and spaced apart along the extension direction of the fixing plate 32. The multiple second support arms 321 can be used to pass through the gaps between multiple first support arms 1241.

[0040] Reference Figure 4 , Figure 5The drive chain 313 is also equipped with a limiting frame 33 for the fixing plate 32 to be embedded. The limiting frame 33 is elongated and extends horizontally. Guide sleeves 331 are integrally provided at both ends of the limiting frame 33. Guide posts 34 that pass through the two guide sleeves 331 are welded to both ends of the base 3. At the same time, a mounting arm 35 is welded to the upper end of the post 31, and a first connecting rod 351 extending vertically downward is welded to one side of the mounting arm 35. The lower end of the first connecting rod 351 is fixed to a fixed motor 352 by bolts. A swing arm 353 is fixed to the output shaft of the fixed motor 352 by bolts. At the end of the swing arm 353 away from the fixed motor 352, multiple third support arms 353 are welded. 1. Multiple third support arms 3531 are spaced apart along the extension direction of the swing arm 353 and are used to pass through the gaps between multiple second support arms 321. A second connecting rod 354 extending vertically downward is welded to one side of the mounting arm 35. A baffle 355 is welded to the lower end of the second connecting rod 354. The baffle 355 is L-shaped. The L-shape formed by the third support arm 3531 and the swing arm 353 works in conjunction with the baffle 355. At the same time, the angle of the baffle 355 is located on the arc trajectory formed by the rotation of the end of the swing arm 353. The baffle 355 can be used to abut against the corrugated cardboard on the third support arm 3531. The baffle 355 can scrape off the corrugated cardboard so that the corrugated cardboard falls neatly.

[0041] Reference Figure 4 Below the baffle 355, there is a storage rack 4 for storing corrugated cardboard. The storage rack 4 includes a base plate 41, a side plate 42 located on the upper side of the base plate 41, and multiple partition plates 43 located on the side wall of the side plate 42 and evenly spaced on the side wall of the side plate 42. A gap is left between the top of the side plate 42 and the baffle 355 for the swing arm 353 to pass through. The four corners of the lower surface of the base plate 41 are fixed with self-locking casters 411 by bolts. At the same time, two vertically downward extending rubber positioning strips 3551 are bonded to the lower side of the baffle 355. The rubber positioning strips 3551 can be used to attach to the outer wall of the partition plate 43.

[0042] Principle: When the corrugated paper is cut into corrugated cardboard by the saw blade 13 in the band saw machine 1 under the drive of the drive component 2, the corrugated cardboard can fall onto the worktable 12. At this time, the feeding cylinder 121 can push the corrugated cardboard on the worktable 12 through the push plate 122, so that the corrugated cardboard falls onto the slide 123 and slides along the slide 123 onto the upper side of the multiple first support arms 1241.

[0043] The drive motor 312 drives the drive sprocket 311 to rotate, which in turn drives the drive chain 313. The drive chain 313 then moves the multiple second support arms 321 on the fixed plate 32, allowing the multiple second support arms 321 to pass through the gaps between the multiple first support arms 1241. At this time, the corrugated cardboard on the first support arms 1241 can fall onto the second support arms 321. Meanwhile, since the fixed plate 32 is embedded in the limiting frame 33, and the guide sleeves 331 at both ends of the limiting frame 33 are fitted onto the guide posts 34, the multiple second support arms 321 can always be kept on a horizontal plane, which is conducive to the stable movement of the corrugated cardboard.

[0044] When the second support arm 321 passes the third support arm 3531, the corrugated cardboard on the second support arm 321 falls onto the third support arm 3531. Then, the fixed motor 352 drives the swing arm 353 and the third support arm 3531 to swing towards the baffle 355. The baffle 355 then comes into contact with the corrugated cardboard on the third support arm 3531, and the corrugated cardboard is scraped off the third support arm 3531. After the corrugated cardboard is scraped off by the baffle 355, the corrugated cardboard can be neatly stacked on the top side of the bottom plate 41, which is limited by the side plate 42 and the partition plate 43, using the storage rack 4 on the ground below the baffle 355. By moving the storage rack 4, the positions of the partition plates 43 of different cavities are aligned with the positions of the baffle 355, and finally the corrugated cardboard can be neatly stored in the storage rack 4.

[0045] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
