Description

Technical Field

[0001] This application relates to the technical field of corrugated paper production, and in particular to a device for correcting the thickness of the adhesive layer of corrugated cardboard. 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 single-wall and double-wall corrugated paperboard. The manufacturing process typically involves processing the base paper into corrugated paper with a wavy core using a corrugating machine, then bonding it together with the linerboard and inner linerboard using adhesives to form a packaging material with a certain strength and cushioning performance. Corrugated paper has many excellent properties. Firstly, it is lightweight and has good structural performance. Its internal corrugated structure resembles an archway, with corrugated sections arranged side-by-side, supporting each other to form a triangular structure, providing good mechanical strength. It can withstand a certain amount of pressure and is elastic, providing good cushioning. This allows it to effectively protect the contents of the package from collisions and compression during transportation and storage. Secondly, the raw materials for corrugated paper are widely available, mainly various plant fibers such as wood, bamboo, reeds, and wheat straw. These raw materials are renewable and relatively inexpensive, making the production cost of corrugated paper more economical. Furthermore, corrugated paper is easy to process and can be cut, folded, and die-cut according to different needs to create packaging containers of various shapes and sizes, such as cartons, boxes, and pallets, meeting the packaging requirements of different products.

[0003] In traditional corrugated paper production, the thickness of the adhesive layer is inconsistent, which leads to errors in the thickness of the corrugated paper during production. It is necessary to correct the thickness of the adhesive layer to ensure that the thickness of the corrugated paper meets the requirements. Therefore, a corrugated paper adhesive layer thickness correction device is needed. To solve the above problems, this application provides a corrugated paper adhesive layer thickness correction device. Utility Model Content

[0004] The purpose of this invention is to provide a device for correcting the thickness of the adhesive layer of corrugated cardboard, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrugated cardboard adhesive layer thickness correction device, comprising a base, slide rails symmetrically installed at both ends of the top of the base, sliders installed on the slide rails, a support frame installed between the tops of the sliders, fixing ears symmetrically installed at both ends of the bottom of the support frame, a support plate installed at the bottom of the fixing ears, limit plates symmetrically installed on both sides of the bottom of the support plate, movable plates installed between the outer sides of the limit plates, a connecting plate installed between the outer sides of the movable plates, a dust cover installed at the bottom of the connecting plate, a grinding roller installed between the inner walls of the dust cover, and a drive motor installed at one outer end of the dust cover.

[0006] Preferably, a limiting block is installed at one top end of the base, a fixing plate is installed at the top end of the base away from the limiting block, an adjusting bolt is installed on the fixing plate, and a clamping plate is installed at one end of the adjusting bolt and at the top of the base.

[0007] Preferably, a servo motor is installed on one inner side wall of the support frame, and a rotating rod is installed on the output shaft of the servo motor. The outer ring surface of the rotating rod is rotatably connected to the inside of the two fixed ears, and an active bevel gear is installed on the outer ring surface of the rotating rod near the two fixed ears.

[0008] Preferably, driven bevel gears are installed on the top of the support plate and near both driving bevel gears, and threaded rods are symmetrically installed at both ends of the bottom of the support plate. The top end of the threaded rod passes through the support plate and connects to the bottom of the driven bevel gear, and the driving bevel gear and the driven bevel gear mesh with each other.

[0009] Preferably, a connecting lug is installed on the outer side of the movable plate and outside the threaded rod, the outer annular surface of the threaded rod is threadedly connected to the inside of the connecting lug, and the two outer ends of the movable plate are slidably connected to the inside of the two limiting plates.

[0010] Preferably, vacuum cleaners are symmetrically installed at both ends of the outer side of the dust cover, and several sets of suction heads are symmetrically installed on the inner side walls of the dust cover.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] This corrugated cardboard adhesive layer thickness correction device, after the servo motor is started, its output shaft drives the rotating rod to rotate in the fixed ear. When the rotating rod rotates, it drives the active bevel gear on it to rotate together. When the active bevel gear rotates, since the active bevel gear and the driven bevel gear mesh with each other, the driven bevel gear will rotate accordingly. The rotation of the driven bevel gear drives the threaded rod to rotate. When the threaded rod rotates, since the threaded rod is threadedly connected to the connecting ear, and the two ends of the movable plate slide in the limit plate, the movable plate will move up and down along the axial direction of the threaded rod. The movement of the movable plate drives the connecting plate and the dust cover to move up and down, thereby adjusting the height of the grinding roller to meet the grinding and correction needs of corrugated cardboard of different thicknesses. After the vacuum cleaner is started, the dust generated during the grinding process is sucked in through the suction heads on both sides of the inner side wall of the dust cover to prevent dust from flying. It is easy to operate and has better practicality. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0020] A device for correcting the thickness of the adhesive layer of corrugated cardboard, as described in the following article. Figure 1 - Figure 5 The system includes a base 1, with slide rails 2 symmetrically mounted on both ends of the top of the base 1. Slide rails 3 are mounted on the slide rails 2. A support frame 4 is mounted between the tops of the slide rails 3. Fixing ears 5 are symmetrically mounted on both ends of the bottom of the support frame 4. A support plate 6 is mounted between the bottom ends of the fixing ears 5. Limiting plates 7 are symmetrically mounted on both sides of the bottom of the support plate 6. Movable plates 8 are mounted between the outer sides of the limiting plates 7. A connecting plate 9 is mounted between the outer sides of the movable plates 8. A dust cover 10 is mounted on the bottom of the connecting plate 9. A grinding roller 11 is mounted between the inner walls of the dust cover 10. A drive motor 22 is mounted on one outer end of the dust cover 10.

[0021] Reference Figure 1 - Figure 2 A limiting block 12 is installed at one end of the top of the base 1. A fixing plate 13 is installed at the end of the top of the base 1 away from the limiting block 12. An adjusting bolt 14 is installed on the fixing plate 13. A clamping plate 15 is installed at one end of the adjusting bolt 14 and at the top of the base 1. The corrugated cardboard is placed on the base 1 with one end against the limiting block 12. Then the adjusting bolt 14 is rotated. The adjusting bolt 14 rotates on the fixing plate 13 and pushes the clamping plate 15 to move toward the corrugated cardboard until the clamping plate 15 clamps and fixes the corrugated cardboard, ensuring that the corrugated cardboard will not move during the sanding process and ensuring the accuracy of sanding and correction.

[0022] Reference Figure 1 - Figure 4 A servo motor 16 is installed on one side wall inside the support frame 4. A rotating rod 17 is installed on the output shaft of the servo motor 16. The outer ring surface of the rotating rod 17 is rotatably connected to the inside of the two fixed ears 5. A drive bevel gear 18 is installed on the outer ring surface of the rotating rod 17 near the two fixed ears 5. After the servo motor 16 is started, its output shaft drives the rotating rod 17 to rotate inside the fixed ears 5. When the rotating rod 17 rotates, it drives the drive bevel gear 18 on it to rotate together. The top of the support plate 6 near the two drive bevel gears... Each bevel gear 18 is equipped with a driven bevel gear 19. Threaded rods 20 are symmetrically installed at both ends of the bottom of the support plate 6. The top end of the threaded rod 20 passes through the support plate 6 and connects to the bottom of the driven bevel gear 19. The driving bevel gear 18 and the driven bevel gear 19 mesh with each other. When the driving bevel gear 18 rotates, the driven bevel gear 19 will rotate accordingly because the driving bevel gear 18 and the driven bevel gear 19 mesh with each other. The rotation of the driven bevel gear 19 drives the threaded rod 20 to rotate.

[0023] Reference Figure 3 - Figure 4A connecting ear 21 is installed on the outer side of the movable plate 8 and outside the threaded rod 20. The outer ring surface of the threaded rod 20 is threadedly connected to the inside of the connecting ear 21. The two outer ends of the movable plate 8 are slidably connected to the inside of the two limiting plates 7. When the threaded rod 20 rotates, because the threaded rod 20 is threadedly connected to the connecting ear 21 and the two ends of the movable plate 8 slide inside the limiting plates 7, the movable plate 8 will move up and down along the axial direction of the threaded rod 20. The movement of the movable plate 8 drives the connecting plate 9 and the dust cover 10 to move up and down, thereby adjusting the height of the sanding roller 11 to meet the sanding and correction needs of corrugated cardboard of different thicknesses.

[0024] Reference Figure 5 The dust cover 10 has vacuum cleaners 23 symmetrically installed at both ends of its exterior. Several sets of suction heads 24 are symmetrically installed on the inner side walls of the dust cover 10. When the sanding roller 11 sands the adhesive layer of the corrugated cardboard, a large amount of dust is generated. After the vacuum cleaner 23 is started, it sucks in the dust generated during the sanding process through the suction heads 24 on the inner side walls of the dust cover 10, preventing dust from flying, improving the working environment, and avoiding the dust from affecting the subsequent processing of the corrugated cardboard.

[0025] The implementation principle of the corrugated cardboard adhesive layer thickness correction device in this application embodiment is as follows: When correcting the thickness of the corrugated cardboard adhesive layer, the servo motor 16 and the vacuum cleaner 23 are both electrically connected to an external power source via a switch. The corrugated cardboard is placed on the base 1 with one end against the limiting block 12. Then, the adjusting bolt 14 is rotated, and the adjusting bolt 14 rotates on the fixing plate 13, pushing the clamping plate 15 towards the corrugated cardboard until the clamping plate 15 clamps and fixes the corrugated cardboard, ensuring that the corrugated cardboard will not move during the sanding process, thus ensuring the accuracy of the sanding correction. The servo motor 16... Preferably, the HBS57 type is used. The servo motor 16 is started by a switch. After starting, the output shaft of the servo motor 16 drives the rotating rod 17 to rotate within the fixed ear 5. When the rotating rod 17 rotates, it drives the active bevel gear 18 to rotate as well. Since the active bevel gear 18 meshes with the driven bevel gear 19, the driven bevel gear 19 will also rotate. The rotation of the driven bevel gear 19 drives the threaded rod 20 to rotate. When the threaded rod 20 rotates, since it is threadedly connected to the connecting ear 21, and both ends of the movable plate 8 slide within the limiting plate 7, the movable plate 8 will move up and down along the axial direction of the threaded rod 20. The movement of the movable plate 8 causes the connecting plate 9 and the dust cover 10 to rise. The height of the sanding roller 11 is adjusted by lowering it to adapt to the sanding and correction requirements of corrugated cardboard of different thicknesses. The support frame 4 can be pushed to slide along the slide rail 2 via the slider 3 for sanding and correction. The vacuum cleaner 23 is preferably a C3-L148B type. The vacuum cleaner 23 is started by switching on the switch. After the vacuum cleaner 23 is started, the dust generated during the sanding process is sucked in through the suction head 24 on both sides of the dust cover 10 to prevent dust from flying, improve the working environment, and avoid the dust from affecting the subsequent processing of corrugated cardboard. It is convenient to operate and more practical. The thread opening angle of the adjusting bolt 14 and the threaded rod 20 is 20 degrees. The thread self-locking condition needs to meet the following formula calculation: self-locking condition = friction coefficient * tan (helix angle) ≥ 1.
