Description

Technical Field

[0001] This utility model relates to the field of paperboard lamination technology, and in particular to a paperboard lamination device for paperboard processing. Background Technology

[0002] Laminating paperboard with a film can improve its smoothness and appearance, as well as its moisture resistance. A laminating machine is required to laminate paperboard. The paperboard is placed on the conveyor belt of the laminating machine, and the conveyor belt moves to transport the paperboard between the upper and lower pressure rollers. At the same time, the unwinding shaft unwinds the film and passes it under the upper pressure roller. The upper pressure roller heat-presses the film onto the paperboard, thus achieving the lamination of the paperboard.

[0003] In common paperboard processing laminating equipment, the paperboard is fed between two pressure rollers, and then the film passes under the upper pressure roller. The upper pressure roller heat-presses the film onto the paperboard. When dust or foreign matter adheres to the surface of the paperboard, the dust or foreign matter particles will cause air bubbles to form on the surface of the laminated paperboard, thereby affecting the lamination quality of the paperboard. Therefore, this application provides a paperboard laminating equipment for paperboard processing to meet the requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a paperboard laminating device for paperboard processing to solve the problem that when dust or foreign matter adheres to the surface of paperboard, the dust or foreign matter particles will cause air bubbles on the surface of the paperboard after lamination, thereby affecting the lamination quality of the paperboard.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A paperboard laminating apparatus for paperboard processing includes a laminating machine, with the paperboard body placed on the conveyor belt of the laminating machine, and further includes:

[0007] An adjustable suction mechanism includes a suction head fixed inside the frame of a laminating machine.

Detailed Implementation

[0028] The following is a detailed description of a paperboard laminating device for paperboard processing provided by this utility model, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0029] like Figures 1-4 As shown, an embodiment of this utility model provides a paperboard laminating device for paperboard processing, including a laminating machine 1, a paperboard body 18 placed on the conveyor belt of the laminating machine 1, and further including:

[0030] Adjustable suction mechanism 2 includes suction head 3 fixed in the frame of laminating machine 1. Suction head 3 is located above cardboard body 18. Suction head 3 has a suction port at the bottom and is horizontally cylindrical. Two pistons 5 are slidably connected inside suction head 3. The pistons 5 are made of rubber. Connecting blocks 6 are fixed on the opposite sides of the two pistons 5. L-shaped blocks 7 are fixed at the bottom of connecting blocks 6. Guide strips 4 are fixed on the side of L-shaped blocks 7 near cardboard body 18. The side of guide strips 4 is in contact with the side of cardboard body 18. Connecting box 14 is connected to the top of suction head 3. Bending pipe 16 is connected to the top of connecting box 14. Centrifugal fan 15 is fixed to the side of laminating machine 1. The end of bending pipe 16 away from connecting box 14 is connected to the air inlet of centrifugal fan 15.

[0031] The conveyor belt of the laminating machine 1 transports the cardboard body 18. During the transport process, two guide strips 4 guide the movement of the cardboard. At the same time, the centrifugal fan 15 operates, sucking the top of the cardboard body 18 through the suction head 3. The centrifugal fan 15 generates a strong suction at the suction port at the bottom of the suction head 3, effectively removing dust and foreign objects from the cardboard body 18. This not only ensures the lamination quality and avoids problems such as bubbles and loose adhesion caused by dust or foreign objects after lamination, but also improves the overall appearance flatness and aesthetics of the laminated product and extends the service life of the laminated product. The guide strips 4 precisely guide the cardboard during the transport process, ensuring that the cardboard enters the suction and subsequent lamination stages in the correct posture, thus improving the stability and accuracy of the entire lamination process.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, two connecting strips 8 are fixed to the top of the guide strip 4, and guide sleeves 9 are fixed to both sides of the connecting strip 8. The inner walls of the connecting strip 8 and the guide sleeves 9 are slidably connected to the outer wall of the suction head 3. A vertical plate 12 is fixed to the top of the suction head 3. The inner walls of the guide sleeves 9 and the connecting strips 8 are slidably connected to the side of the vertical plate 12. A knob bolt 13 is threadedly connected to the side of the guide sleeve 9, and the end of the knob bolt 13 fits against the side of the vertical plate 12. The connecting strip 8 and the guide sleeve 9 provide stable support and a precise guiding path for the movement of the guide strip 4. Through the cooperation of the knob bolt 13 and the vertical plate 12, the position of the guide strip 4 can be conveniently locked and flexibly adjusted. When facing cardboard bodies 18 of different widths, simply loosen the knob bolt 13, and the guide strip 4 can slide at the bottom of the suction head 3. After adjusting to the appropriate position, tighten the knob bolt 13 to fix it, which improves the adaptability to cardboard bodies 18 of different sizes.

[0033] like Figure 2 and Figure 4As shown, in this embodiment, the guide sleeve 9 includes an arc-shaped portion 10 and a U-shaped bend portion 11 connected in sequence. Both the arc-shaped portion 10 and the U-shaped bend portion 11 are fixed to the side of the connecting strip 8. The inner wall of the arc-shaped portion 10 is slidably connected to the outer wall of the suction head 3, and the inner wall of the U-shaped bend portion 11 is slidably connected to the side of the vertical plate 12. The knob bolt 13 is threadedly connected to the side of the U-shaped bend portion 11. When the guide sleeve 9 moves, it drives the arc-shaped portion 10 to move along the outer wall of the suction head 3 and drives the U-shaped bend portion 11 to move along the side of the vertical plate 12, thereby ensuring the stability of the guide strip 4 movement and effectively preventing the guide strip 4 from skewing or deviating during adjustment or operation, thus enhancing the guiding accuracy of the cardboard body 18 movement.

[0034] like Figure 2 and Figure 4 As shown, in this embodiment, the center of the arc-shaped part 10 is located on the central axis of the suction head 3. This design, where the center of the arc-shaped part 10 is located on the central axis of the suction head 3, ensures that the guide sleeve 9 is subjected to uniform force when sliding along the suction head 3, resulting in a more stable and accurate movement trajectory. This effectively avoids phenomena such as jamming and jumping caused by improper cooperation between the guide sleeve 9 and the suction head 3, ensuring the linear motion accuracy of the guide strip 4 in the horizontal direction. This ensures that the cardboard body 18 always maintains the correct travel path during movement, greatly improving the reliability of the guide.

[0035] like Figure 4 As shown, in this embodiment, the end of the knob bolt 13 away from the vertical plate 12 is provided with anti-slip texture; the anti-slip texture design on the knob bolt 13 can firmly hold the knob bolt 13 and apply appropriate torque, so as to easily loosen or tighten the knob bolt 13.

[0036] like Figure 1 As shown, in this embodiment, a connecting plate 17 is fixed to the top of the frame of the laminating machine 1, and the connecting plate 17 is fixed to the end of the suction head 3; the connecting plate 17 firmly fixes the suction head 3 to the top of the frame of the laminating machine 1, thereby enhancing the stability of the suction head 3 during operation.

[0037] like Figure 1 As shown, in this embodiment, the side of the connecting plate 17 is fixed with a reinforcing rib, which is fixed to the top of the frame of the laminating machine 1. The setting of the reinforcing rib further strengthens the connection strength between the connecting plate 17 and the frame, improves the fixing stability of the connecting plate 17, and thus improves the installation strength of the suction head 3.

[0038] like Figure 1 As shown, in this embodiment, the lower surface of the guide strip 4 is parallel to the upper surface of the conveyor belt of the laminating machine 1; the design that the lower surface of the guide strip 4 is parallel to the surface of the conveyor belt enables the cardboard body 18 to maintain a horizontal and stable state when moving on the conveyor belt.

[0039] Working principle: First, place the cardboard body 18 on the conveyor belt of the laminating machine 1. After starting the laminating machine 1, the conveyor belt starts to run, driving the cardboard body 18 to move towards the laminating area.

[0040] When the cardboard body 18 moves on the conveyor belt between the two guide bars 4, the guide bars 4 guide the movement of the cardboard body 18. When the cardboard body 18 passes the bottom of the suction head 3, the centrifugal fan 15 operates to generate negative pressure in the suction head 3. The top of the cardboard body 18 is sucked through the suction port at the bottom of the suction head 3 to clean the top of the cardboard body 18 and prevent dust and foreign objects from affecting the lamination quality in the subsequent lamination process.

[0041] The knob bolt 13 on the side of the guide sleeve 9 can be loosened, and the end of the knob bolt 13 separates from the side of the vertical plate 12, so that the guide strip 4 can move freely in the axial direction of the suction head 3. According to the width of the cardboard body 18, the distance between the two guide strips 4 can be manually adjusted. After the adjustment is completed, the knob bolt 13 is tightened so that the end of the knob bolt 13 abuts against the side of the vertical plate 12, and the position of the guide strip 4 is fixed to adapt to different sizes of cardboard bodies 18.

[0042] When the spacing of the guide strip 4 is adjusted, the guide strip 4 drives the piston 5 to move along the inner wall of the suction head 3 through the L-shaped block 7 and the connecting block 6, changing the area of ​​the suction port at the bottom of the suction head 3 acting on the cardboard body 18, so that it can automatically adapt to different sizes of cardboard bodies 18, thereby more efficiently sucking up dust or foreign objects on the cardboard body 18 and achieving a comprehensive cleaning of the cardboard body 18.

[0043] After the above cleaning, the cardboard body 18 continues to move on the conveyor belt and enters the lamination area. At this time, the film passes the bottom of the upper pressure roller and is hot-pressed onto the cleaned cardboard body 18 by the upper pressure roller to complete the lamination operation.

[0044] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
