Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper production, in particular to a corrugated paper laminating device for preventing the deflection of corrugated paperboard. Background Art

[0002] Corrugated paper is a paper material with a special structure. It is made of corrugated core paper and boxboard paper on both sides. Most of the corrugated paper is laminated by a laminating device during production. The surface of the laminated corrugated paper has an additional layer of thin and transparent plastic film, which not only improves the gloss and firmness of the printed matter and extends the service life, but also increases the protection against moisture, water, dirt, wear, folding, and chemical corrosion. However, when laminating the existing corrugated paper, it is not easy for the two sides of the plastic film to be completely flush with the two end surfaces of the corrugated board, which reduces the fineness of the lamination.

[0003] In order to address the above problems, the existing Chinese patent with announcement number CN220784933U proposes a high-precision laminating structure for corrugated cardboard. The device limits the width direction of the corrugated cardboard through an anti-deviation component to prevent the corrugated cardboard from deviating during movement, thereby improving the fineness of the lamination.

[0004] However, although the above-mentioned high-precision laminating structure for corrugated cardboard can limit the width direction of the corrugated cardboard through the anti-deviation component to prevent the corrugated cardboard from deviating during movement, when the high-precision laminating structure for corrugated cardboard limits the corrugated cardboard through the limiting plate, the friction between the limiting plate and the corrugated paper will increase, which may easily cause the edge of the corrugated paper to be damaged due to excessive force. Therefore, the utility model provides a corrugated paper laminating device for preventing the corrugated cardboard from deviating to meet the demand. Utility Model Content

[0032] like Figures 1 to 7As shown, an embodiment of the utility model provides a corrugated paper laminating device for preventing the deflection of corrugated paperboard, comprising a mounting plate 1, a transmission roller mechanism 2 and a laminating mechanism 7, a support plate 11 is provided on the mounting plate 1, two groups of support frames 10 are symmetrically provided on the support plate 11, a slider 15 is relatively slidably connected in the support frame 10, a roller 8 that contacts the corrugated paper body 3 is rotatably connected to the slider 15, a slide groove 17 is provided on the support frame 10 for the slider 15 to slide, a spring 18 fixedly connected to the slider 15 is provided in the slide groove 17, and a driving component 9 for driving the two groups of support frames 10 to move relative to each other is provided on the mounting plate 1.

[0033] Specifically, the two groups of support frames 10 are driven to move relative to each other by the driving assembly 9. When the support frame 10 drives the roller 8 to squeeze the corrugated paper body 3, the spring 18 can buffer and release force to avoid damage to the edge of the corrugated paper body 3 due to too tight clamping, thereby reducing the friction between the roller 8 and the corrugated paper body 3, and solving the problem that when the existing corrugated paperboard high-precision coating structure limits the corrugated paper through the limiting plate 16, the friction between the limiting plate 16 and the corrugated paper will increase, thereby easily causing the edge of the corrugated paper to be damaged due to excessive force.

[0034] It should be noted that the laminating mechanism 7 and the transmission roller mechanism 2 are prior arts and are not described here. The present embodiment aims to improve the Chinese patent with announcement number CN220784933U, wherein the laminating mechanism 7 can adopt the method proposed in the above patent. Secondly, the driving component 9 can be an electric push rod, hydraulic push rod or the like in the prior art that can drive the two support frames 10 to move relative to each other.

[0035] like Figure 5 As shown, in this embodiment, there are multiple rollers 8, and they are arranged along the length direction of the support frame 10, and the support frame 10 is a U-shaped structure.

[0036] like Figure 6 and Figure 7 As shown, in the present embodiment, the second slide groove 17 is extended along the sliding direction of the support frame 10, and the limiting plate 16 is fixedly connected to the second slider 15. A slot 19 is penetrated through the support frame 10 opposite to the limiting plate 16, and the limiting plate 16 is located at the bottom of the spring 18. Specifically, the setting of the limiting plate 16 can prevent the spring 18 from bending, and can also prevent external impurities from entering the second slide groove 17, thereby ensuring the normal use of the spring 18. It should be noted that the second slide groove 17 and the slot 19 are connected, and the slot 19 can be used for the limiting plate 16 to be inserted.

[0037] like Figure 2 and Figure 3As shown, in this embodiment, a mounting frame 13 is fixedly connected to the bottom of the mounting plate 1, and a plurality of traction rollers 12 that are in contact with the bottom of the corrugated paper body 3 are relatively rotatably connected to the mounting frame 13. The plurality of traction rollers 12 are extended along the transmission direction of the corrugated paper body 3, and the length of the traction rollers 12 is less than the width of the corrugated paper body 3.

[0038] like Figures 1 to 4 As shown, in this embodiment, a fixing plate 5 is fixedly connected to the bottom of the mounting plate 1, a cutting mechanism 6 is relatively fixedly connected to the upper edge of the fixing plate 5 along the corrugated paper body 3, a winding roller 4 is rotatably connected to the mounting plate 1, and a motor 14 for driving the winding roller 4 to rotate is fixedly connected to the mounting plate 1, and the winding roller 4 is configured to roll up the waste generated by the cutting mechanism 6 cutting the corrugated paper body 3. Specifically, the cutting mechanism 6 is divided into two groups and is relatively arranged at the edge of the corrugated paper body 3, and is suitable for cutting the extra film on the side of the corrugated paper body 3. The cutting mechanism 6 is the prior art, for example, it can be a blade, a cutting wheel, etc., and the speed of the motor 14 can be adjusted according to the transmission speed and the coating speed of the corrugated paper body 3, and the adjustment method is the prior art; the waste can be collected by the winding roller 4, which saves the time of manual waste collection and improves the coating efficiency of the corrugated paper body 3.

[0039] like Figure 5 As shown, in this embodiment, the driving assembly 9 includes a double-headed screw 91, which is rotatably set on the support plate 11, two sliding blocks 92, one end of which is fixedly connected to the two groups of support frames 10 respectively, and the other end is sleeved and threadedly connected to the two ends of the double-headed screw 91, and the support plate 11 is provided with a slide groove 93 for the sliding block 92 to slide.

[0040] Working principle:

[0041] The corrugated paper body 3 is passed through the transmission roller mechanism 2, and then the two sliders 92 are driven to move relatively along the slide groove 93 by rotating the double-headed screw 91 according to the width of the corrugated paper body 3, and the slider 92 drives the support frame 10 to move relatively, so that the roller 8 contacts the edge of the corrugated paper body 3. The setting of the spring 18 can prevent the roller 8 from damaging the edge of the corrugated paper body 3. Then, the film laminating operation is performed by the film laminating mechanism 7, and the corrugated paper body 3 is pulled by the transmission roller mechanism 2, so that the cutting mechanism 6 cuts the excess film, and the film is cut by the film laminating mechanism 7. The motor 14 drives the winding roller 4 to collect the excess film. Secondly, the driving roller can ensure the stability of the corrugated paper body 3, increase the quality of the film coating of the corrugated paper body 3, and the overall operation is simple. The friction on the corrugated paper body 3 is reduced by the roller 8, thereby avoiding damage to the edge of the corrugated paper body 3. This solves the problem that when the existing corrugated paperboard high-precision coating structure limits the corrugated paper through the limiting plate 16, the friction between the limiting plate 16 and the corrugated paper will increase, thereby easily causing the edge of the corrugated paper to be damaged due to excessive force.
