Description

Technical Field

[0001] This utility model relates to the field of paperboard production technology, specifically to a laminating device for paperboard processing. Background Technology

[0002] Lamination, also known as "plastic coating," "adhesive lamination," or "film application," refers to the process of applying a transparent plastic film to the surface of printed materials through heat and pressure. This process protects the material and enhances its gloss. Lamination is mainly divided into semi-automatic and fully automatic operations. Although there are some differences in the specific operations of semi-automatic and fully automatic lamination, the principle is the same: first, an adhesive is applied to the plastic film using a roller coating device; then, the film is softened by a hot press roller; finally, the printed material coated with the adhesive is pressed against the film to form a paper-plastic composite laminated product. Composite paperboard also requires lamination during the processing.

[0003] The prior art proposes a Chinese patent with publication number CN220946782U to solve the aforementioned technical problems. The technical solution disclosed in this patent document is as follows: A laminating device for cardboard processing includes a mounting plate, a fixing plate, and a connecting plate. Two mounting plates are spaced apart from each other, and a belt conveyor mechanism is provided between the two mounting plates. A laminating machine is located on and connected to the two mounting plates. Two fixing plates are respectively connected to the upper ends of the two mounting plates and are located in front of the laminating machine. The connecting plate is connected to the two fixing plates, and a flattening component is provided at the bottom end of the connecting plate. The conveyor belt of the belt conveyor mechanism is provided with multiple limiting components for limiting the cardboard. The upper end of the limiting components is located below the cardboard. Two cutting blades are slidably provided at the front end of the connecting plate, and a driving component for driving the two cutting blades is provided on the connecting plate. This utility model can effectively limit and position the cardboard through the limiting components, so that it can stably pass through the laminating machine and the flattening component, thereby ensuring its laminating quality, and the excess film on the cardboard is cut off under the action of the cutting blades.

[0004] However, the blade tip of the existing cutter that meets the cardboard is prone to vibration during equipment operation, affecting the cutting accuracy. Moreover, the lamination is applied to the cardboard after heating. Although it is flattened by the flattening component, it is still in a softened state with low hardness. When the cutter encounters an obstacle, it is easy to pull or squeeze the edge of the lamination at the obstruction point, affecting the flatness of the lamination and thus affecting the quality of the finished product. Utility Model Content

[0005] The purpose of this invention is to provide a laminating device for cardboard processing to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A laminating apparatus for cardboard processing includes a laminating machine, a flattening chamber, and a conveyor belt. The flattening chamber is equipped with a cutting and separating component, which includes a cardboard flattening roller. A rotating collar is slidably sleeved on one end of the cardboard flattening roller. A C-shaped mounting bracket is fixedly connected to the upper surface of the rotating collar. A connecting column is fixedly connected to one side of the C-shaped mounting bracket. A cutter is fixedly connected to the end of the connecting column away from the C-shaped mounting bracket.

[0008] An electric push rod is fixedly connected to the side of the cutter away from the connecting column. An inner arc-shaped blade is fixedly connected to the bottom surface of the cutter. An auxiliary limiting component for auxiliary fixing of the cutter is provided on the bottom surface of the C-shaped mounting bracket. The auxiliary limiting component includes a positioning frame plate sleeved on one side of the cutter. One end of the cutter abuts against the inner wall of the positioning frame plate.

[0009] A further improvement of this utility model is that the electric push rod is fixedly connected to the inner wall of the flattening chamber.

[0010] A further improvement of the present invention is that the auxiliary limiting component further includes a first abutting block and a second abutting block symmetrically distributed on the inner wall of the positioning frame plate, wherein the ends of the first abutting block and the second abutting block that are close to each other abut against the outer wall of the cutter.

[0011] A further improvement of this utility model is that rubber pads are fixedly connected to the ends of the first abutting block and the second abutting block that are close to each other.

[0012] A further improvement of this utility model is that: one end of the cardboard flattening roller is fixedly connected to an auxiliary limiting roller, and the end of the auxiliary limiting roller away from the cardboard flattening roller is rotatably connected to the inner wall of the flattening chamber.

[0013] A further improvement of this utility model is that a compensation collar is fixedly sleeved on the outer wall of the auxiliary limiting roller.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a laminating device for cardboard processing. An auxiliary limiting assembly consisting of a positioning frame plate, a first abutment block, and a second abutment block fixes the cutter, ensuring its stability during cutting and preventing cutting obstruction due to vibration, thus ensuring smooth cutting. This prevents the problem of the cutter encountering obstacles that could pull or squeeze the laminating edge, affecting the flatness of the lamination and consequently the quality of the finished product.

[0016] 2. This utility model provides a laminating device for cardboard processing. The arc-shaped design of the inner arc blade causes the film to be cut from top to bottom in a downward parabolic path during cutting, allowing the cardboard itself to be used as a support for cutting, effectively improving the cutting effect. In addition, during the cutting operation, the cardboard flattening roller can apply auxiliary pressure to the cardboard to prevent it from shaking or shifting, further ensuring the quality of cutting and laminating.

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] Example 1

[0025] like Figure 1-4As shown, this utility model provides a laminating device for cardboard processing, including a laminating machine 1, a flattening chamber 2 and a conveyor belt 3. The flattening chamber 2 is provided with a cutting and separating component 5. The cutting and separating component 5 includes a cardboard flattening roller 6. One end of the cardboard flattening roller 6 is slidably sleeved with a rotating collar 12. A C-shaped mounting bracket 10 is fixedly connected to the upper surface of the rotating collar 12. A connecting post 11 is fixedly connected to one side of the C-shaped mounting bracket 10. A cutter 8 is fixedly connected to the end of the connecting post 11 away from the C-shaped mounting bracket 10.

[0026] An electric push rod 9 is fixedly connected to the side of the cutter 8 away from the connecting post 11. An inner arc-shaped blade 13 is fixedly connected to the bottom surface of the cutter 8. An auxiliary limiting component for auxiliary fixing of the cutter 8 is provided on the bottom surface of the C-shaped mounting bracket 10. The auxiliary limiting component includes a positioning frame plate 14 sleeved on one side of the cutter 8. One end of the cutter 8 abuts against the inner wall of the positioning frame plate 14.

[0027] The electric push rod 9 is fixedly connected to the inner wall of the flattening chamber 2.

[0028] Example 2

[0029] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the auxiliary limiting component further includes a first abutting block 15 and a second abutting block 16 symmetrically distributed on the inner wall of the positioning frame plate 14, and the ends of the first abutting block 15 and the second abutting block 16 that are close to each other abut against the outer wall of the cutter 8 respectively.

[0030] Rubber pads are fixedly connected to the ends of the first abutment block 15 and the second abutment block 16 that are close to each other.

[0031] An auxiliary limiting roller 7 is fixedly connected to one end of the cardboard flattening roller 6, and the end of the auxiliary limiting roller 7 away from the cardboard flattening roller 6 is rotatably connected to the inner wall of the flattening chamber 2.

[0032] The outer wall of the auxiliary limiting roller 7 is fixedly fitted with a compensation collar 18.

[0033] The working principle of this cardboard processing laminating device will be explained in detail below.

[0034] like Figure 1-4 As shown, there are two sets of cardboard flattening rollers 6, symmetrically distributed at both ends of the C-shaped mounting frame 10. When cutting and separating excess film on the cardboard, the electric push rod 9 is activated, pushing the cutter 8 to the size that matches the cardboard.

[0035] As the cardboard passes through the cutter 8, the inner curved blade 13 removes excess film. During the cutting process, the back of the cutter 8 is in contact with the edge of the cardboard, allowing for precise cutting via the inner curved blade 13.

[0036] Furthermore, during the cutting process, the positioning frame plate 14, the first abutting block 15, and the second abutting block 16 fix the cutter 8, ensuring that the cutter 8 remains stable and preventing the vibration of the cutter 8 from causing cutting obstruction.

[0037] Because the inner arc-shaped blade 13 is arc-shaped, when removing excess film from the cardboard, the film is cut from top to bottom in a downward parabolic path, thus allowing the cardboard itself to support the film and further improve the cutting effect.

[0038] While the cutter 8 is cutting, the flattening chamber 2 has already flattened the cardboard, and the cardboard flattening roller 6 applies auxiliary pressure to the cardboard to prevent it from shaking or shifting.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
