Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard processing, and in particular to a high-strength corrugated cardboard hot-pressing laminating machine. Background Technology

[0002] Corrugated cardboard is generally made of flat face paper and bent core paper bonded together. Corrugated cardboard is classified into double-layer, triple-layer, five-layer, and seven-layer corrugated cardboard according to the number of material layers. Double-layer corrugated cardboard, also known as single-faced corrugated cardboard, is made of one face paper and one corrugated core paper bonded together. Triple-layer corrugated cardboard, also known as double-faced or double-faced single-faced corrugated cardboard, consists of an outer face paper, an inner face paper, and one corrugated core paper. Five-layer corrugated cardboard is similar, with one face paper and one core paper bonded together on top of three layers of corrugated cardboard. High-strength corrugated cardboard is often used for packaging heavy goods. Due to the high strength required, existing high-strength corrugated cardboard is often three-layered or more.

[0003] Before corrugated cardboard is heat-pressed, the paper usually needs to be cut into a certain shape and size before being fed into the heat-pressing machine. During the actual cutting process, some paper scraps are generated. After cutting, a large amount of scraps usually remain on the surface of the paper. In existing technologies, these scraps are often cleaned manually. Reference document CN220409841U provides a corrugated cardboard heat-pressing machine. During use, the cardboard to be pressed is placed on the bottom pressure plate, causing the brushes on the brush rollers to contact the cardboard on the bottom pressure plate. Upon contact, the motor drives the brush roller to rotate, which cleans the surface of the cardboard. The vacuum cleaner then uses its suction hood to remove debris from the cardboard surface. The electric slide moves the suction hood and brush roller along the cardboard, thus cleaning the entire surface of the cardboard. By using the brush roller to clean the surface of the cardboard and the vacuum cleaner and suction hood to remove debris, this method can replace manual cleaning of cardboard surface debris, improving the efficiency and effectiveness of cleaning cardboard surface debris, thereby improving the working efficiency and hot pressing effect of the laminating machine.

[0004] During the cleaning process described above, a brush is used to brush the cardboard to remove debris. However, as the brush moves forward, it comes into contact with the cardboard and is pushed by the brush, causing the cardboard to shift. This hinders the cleaning process and affects the subsequent pressing of the cardboard. To address these issues, a solution is proposed below. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength corrugated cardboard hot-pressing laminating machine to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A high-strength corrugated cardboard hot press laminating machine includes a base and a laminating machine body mounted on the base. The laminating machine body includes a column, a hot press component, and a lower pressure plate. The hot press component is mounted on the bottom side of one side of the column, and the lower pressure plate is mounted on the top of the base. The lower pressure plate and the hot press component cooperate vertically. A support plate is mounted on the base, located between the column and the lower pressure plate. Two sliders are slidably mounted on the support plate, and two limiting plates are mounted on each slider. The two limiting plates are slidably mounted on the lower pressure plate. A driving assembly for driving the two sliders to slide is provided on the support plate. An electric slide rail is also mounted on the top of the base, and a second slider is slidably mounted on the electric slide rail. A second support plate is mounted on the top of the second slider, and a dust removal assembly corresponding to the lower pressure plate is provided on the second support plate.

[0008] Preferably, the drive assembly includes a double-ended screw and a drive motor. A wide slot is provided on the side of the support plate near the lower pressure plate. The double-ended screw is rotatably disposed in the wide slot. Two sliders are slidably disposed on both sides of the wide slot. One end of each slider is threadedly engaged with both ends of the double-ended screw. The drive motor is mounted on the side wall of the support plate. The output shaft of the drive motor passes through the support plate and is fixedly connected to the double-ended screw.

[0009] Preferably, the dust removal assembly includes a vacuum cleaner, a suction pipe, a dust hood, and a brush. The vacuum cleaner is mounted on the top of the second support plate. A support plate is mounted on the side of the second support plate near the lower pressure plate. A second drive motor is mounted on the side wall of the support plate. The output shaft of the second drive motor passes through the support plate and is fixed with a connecting rod. The dust hood is disposed on the side wall of the support plate. The bottom of the dust hood has an open structure. The brush is rotatably disposed inside the dust hood. One end of the connecting rod passes through the dust hood and is fixedly connected to the brush. One end of the brush is disposed outside the dust hood. A third support plate, connected to the dust hood, is also fixed on the side wall of the support plate. One end of the suction pipe is connected to the vacuum cleaner, and the other end of the suction pipe is connected to the top of the dust hood.

[0010] Preferably, a dust collection hopper is installed on the inner top surface of the dust collection hood, and one end of the dust collection pipe passes through the dust collection hood and is connected to the dust collection hopper.

[0011] Preferably, the length of the electric slide rail is greater than the length of the lower pressure plate, and the dust removal component is located outside the lower pressure plate in the initial state.

[0012] Preferably, the slider and the limiting plate are detachably connected. The slider has a trapezoidal groove on the side near the lower pressure plate. One side of the limiting plate is a trapezoidal structure that matches the trapezoidal groove. The limiting plate is slidably disposed in the trapezoidal groove. The side wall of the slider is threaded with a locking bolt. The limiting plate is fixed by the locking bolt.

[0013] Beneficial effects: When corrugated cardboard needs to be processed, drive motor one can be started, which drives the double-headed screw to rotate. The double-headed screw drives the two sliders one to move, which in turn drives the two limiting plates to move. The two limiting plates can limit the corrugated cardboard to prevent it from shifting. This prevents the corrugated cardboard from shifting during subsequent cleaning. The limiting plates are relatively thin, with a thickness lower than that of the corrugated cardboard. This allows the limiting plates to also limit and clamp the corrugated cardboard during hot pressing, preventing it from shifting during pressing and affecting the bonding effect.

[0021] See Figures 1 to 6As shown, a high-strength corrugated cardboard heat-pressing laminating machine includes a base 1 and a laminating machine body 2 mounted on the base 1. The laminating machine body 2 includes a column 3, a heat-pressing component 4, and a lower pressure plate 5. The heat-pressing component 4 is mounted on the bottom side of one side of the column 3, and the lower pressure plate 5 is mounted on the top of the base 1. The lower pressure plate 5 and the heat-pressing component 4 are fitted together vertically. A support plate 6 is mounted on the base 1, located between the column 3 and the lower pressure plate 5. Two sliders 7 are slidably mounted on the support plate 6, and two limiting plates 8 are mounted on each slider 7. The sliding assembly 8 is located on the lower pressure plate 5. The support plate 6 is equipped with a drive assembly 9 for driving the two sliders 7 to slide. When the corrugated cardboard needs to be processed, the drive assembly 9 can be activated first. The drive assembly 9 drives the two sliders 7 to slide along the support plate 6. The two sliders 7 drive the two limiting plates 8 to slide along the limiting slide rail on the surface of the lower pressure plate 5. The corrugated cardboard is placed between the two limiting plates 8. By moving the limiting plates 8, the corrugated cardboard can be limited and clamped, preventing the corrugated cardboard from shifting during subsequent processing.

[0022] The limiting plate 8 is relatively thin, thinner than the corrugated cardboard, ensuring that it does not affect the bonding between the lower pressure plate 5 and the hot press component 4 during hot pressing. The limiting plate 8's clamping action on the corrugated cardboard prevents it from shifting during pressing, thus ensuring a good bonding result. Specifically, during the cleaning stage: it counteracts the lateral thrust generated by the brush cleaning, controlling the cardboard displacement to within 0.5mm, solving the displacement problem caused by friction in existing technologies; during the hot pressing stage: the precise positioning of the cardboard edge by the limiting plate 8 controls the bonding deviation to within 1mm, as required by industry standards, avoiding defects such as weak bonding and edge wrinkles caused by cardboard shift.

[0023] The slider 7 and the limiting plate 8 are detachably connected. The slider 7 has a trapezoidal groove 25 on the side near the lower pressure plate 5. The limiting plate 8 has a trapezoidal structure on one side that matches the trapezoidal groove 25. The limiting plate 8 is slidably disposed in the trapezoidal groove 25. The side wall of the slider 7 is threaded with a locking bolt. The limiting plate 8 is fixed by the locking bolt. By detaching and connecting the slider 7 and the limiting plate 8, different lengths and thicknesses of the limiting plate 8 can be selected according to actual needs during actual use. When replacing the limiting plate 8, the locking bolt on the side wall of the slider 7 can be removed first, so that the sliding of the limiting plate 8 is no longer limited. The limiting plate 8 can be disassembled and replaced by sliding the limiting plate 8.

[0024] The drive assembly 9 includes a double-headed screw 14 and a drive motor 15. A wide slot is provided on the side of the support plate 6 near the lower pressure plate 5. The double-headed screw 14 is rotatably mounted in the slot, and two sliders 7 are slidably mounted on opposite sides of the slot. One end of each slider 7 is threaded into both ends of the double-headed screw 14. The drive motor 15 is mounted on the side wall of the support plate 6, and its output shaft passes through the support plate 6 and is fixedly connected to the double-headed screw 14. When it is necessary to push the two sliders 7 to slide, the drive motor 15 can be started first. The output shaft of the drive motor 15 drives the double-headed screw 14 to rotate. The rotation of the screw causes the two sliders 7 to slide synchronously towards or away from each other along the guide rail of the wide slot, thereby driving the limiting plate 8 to adjust the spacing. This symmetrical threaded transmission structure ensures that the two limiting plates 8 approach or move away from the cardboard at the same speed, achieving centering clamping with a clamping error ≤0.3mm. It avoids cardboard tilting caused by unilateral force and provides a precise positioning reference for subsequent dust removal and hot pressing processes.

[0025] The base 1 is also equipped with an electric slide rail 10. A slider 2 11 is slidably mounted on the electric slide rail 10. A support plate 2 12 is mounted on the top of the slider 2 11. A dust removal component 13 corresponding to the lower pressure plate 5 is provided on the support plate 2 12. When the corrugated cardboard is clamped, the dust removal component 13 can be activated to remove dust from the surface of the cardboard.

[0026] The dust removal assembly 13 includes a vacuum cleaner 16, a suction pipe 17, a dust hood 18, and a brush 19. The vacuum cleaner 16 is mounted on the top of the support plate 22. A support plate 20 is mounted on the side of the support plate 22 near the lower pressure plate 5. A drive motor 21 is mounted on the side wall of the support plate 20. The output shaft of the drive motor 21 passes through the support plate 20 and is fixed with a connecting rod 22. The dust hood 18 is set on the side wall of the support plate 20. The bottom of the dust hood 18 has an open structure. The brush 19 is rotatably set inside the dust hood 18. One end of the connecting rod 22 passes through the dust hood 18 and is fixedly connected to the brush 19. One end of the brush 19 is set outside the dust hood 18. A support plate 3 23 connected to the dust hood 18 is also fixed on the side wall of the support plate 20. One end of the suction pipe 17 is connected to the vacuum cleaner 16, and the other end of the suction pipe 17 is connected to the top of the dust hood 18.

[0027] When vacuuming is required for corrugated cardboard, vacuum cleaner 16 can be started first. A small industrial vacuum cleaner can be used. After vacuum cleaner 16 is turned on, drive motor 21 can be started. Drive motor 21 can drive connecting rod 22 to rotate, which in turn drives brush 19 to rotate. The length of electric slide rail 10 is greater than the length of lower pressure plate 5. Dust removal assembly 13 is initially located outside lower pressure plate 5. By placing dust removal assembly 13 outside lower pressure plate 5, it prevents it from affecting the operation of hot pressing component 4 during subsequent pressing. Vacuum cleaner 16 and drive motor 21... After all motors 21 are turned on, the electric slide rail 10 can be started. The electric slide rail 10 can drive the slider 11 to slide, and the slider 11 can drive the top support plate 12 to move. The support plate 12 can drive the top support plate 20 to move. The support plate 20 supports the dust cover 18 through the support plate 23. During the movement of the support plate 20, the brush 19 will brush the upper surface of the corrugated cardboard, so that the waste material attached to the corrugated cardboard can be brushed off. Then, through the cooperation of the vacuum cleaner 16 and the suction pipe 17, the waste material is sucked into the vacuum cleaner 16.

[0028] A dust collection hopper 24 is installed on the inner top surface of the dust collection hood 18. One end of the dust collection pipe 17 passes through the dust collection hood 18 and is connected to the dust collection hopper 24. The dust collection hopper 24 has a structure that is larger at the bottom and smaller at the top. The dust collection hopper 24 and the brush 19 are arranged side by side. The dust collection hopper 24 can gather waste materials. The waste materials are sucked into the dust collection pipe 17 through the connection between the dust collection pipe 17 and the dust collection hopper 24, and then discharged into the vacuum cleaner 16 for collection and treatment.
