Description

Technical Field

[0001] The utility model relates to the technical field of paper production, in particular to a laminating device for ultra-high-strength special paper. Background Art

[0002] Ultra-high-strength specialty paper is a paper product with high mechanical properties and special functions. Compared with conventional paper, it has significantly enhanced physical properties such as tensile strength, tear strength, burst resistance and toughness. Compared with conventional paper, ultra-high-strength specialty paper has relatively more layers, generally five or more layers, which generally include a middle layer for increasing strength, fiber layers on both sides of the middle layer for tear resistance, and a surface layer connected to the fiber layer for protection.

[0003] Due to some characteristics of ultra-high strength specialty paper, there are some problems in the production of ultra-high strength specialty paper. First, due to cost issues, ultra-high strength specialty paper is only suitable for specific occasions, so the demand for ultra-high strength specialty paper is relatively small, and the number of ultra-high strength specialty paper layers is large, which makes it difficult to directly use the conventional corrugated paper pressing method and continuously press through the pressing roller.

[0004] For small batch production, each raw material layer can be cut to a set size before pressing, but ultra-high strength special paper has at least five layers, and the number of pressing times is much higher than that of conventional paper. This results in the need for multiple raw material stacking areas, which takes up a lot of space, and multiple sets of transfer and pressing devices are required to cooperate with each other, which is costly.

[0035] The utility model is further described below in conjunction with the accompanying drawings:

[0036] like Figure 1-Figure 5As shown, the laminating device for ultra-high strength special paper includes a first surface layer laminating device 1, an upper laminating mechanism 4, an intermediate layer conveyor belt 2, an intermediate layer glue coating roller group 3, a clamping conveyor belt 5, a discharge conveyor belt 7, a second surface layer laminating device 9 and a lower laminating mechanism 8.

[0037] The first surface layer pressing device 1 comprises a surface layer pressing mechanism 11 for continuously pressing the surface layer and the fiber layer, a composite layer conveyor belt 13 is provided at the discharge end of the surface layer pressing mechanism 11, the composite layer conveyor belt 13 is used to convey the composite layer 102 formed by pressing the surface layer and the fiber layer, a cutting mechanism 12 is provided above the conveyor belt for cutting the composite layer 102, and a storage mechanism 14 for temporarily stacking the composite layer 102 is provided at one end of the composite layer conveyor belt 13 away from the surface layer pressing mechanism 11, the storage mechanism 14 has a discharge structure for discharging paper;

[0038] The surface layer pressing mechanism 11 includes two raw material drums 111 for mounting raw material rolls, a plurality of guide rollers 112 for guiding the surface layer or fiber layer, a surface layer glue coating roller 113 for coating the surface layer or fiber layer with glue, and a pressing roller group 114 for pressing the surface layer and the fiber layer. The surface layer pressing mechanism 11, the cutting mechanism 12, and the composite layer conveyor belt 13 are all conventional prior arts and will not be described in detail here.

[0039] The storage mechanism 14 includes a storage platform 141, which is provided with a storage trough 142 for temporarily storing the composite layer 102, and the discharge structure includes a discharge roller 143 installed at the bottom of the storage trough 142, and a discharge port 144 is provided on the side of the storage trough 142 for only one composite layer 102 to pass through. In other embodiments, the enclosure on the left side of the storage trough 142 can slide in the up and down direction, and the enclosure can be fixed by friction, so that the height of the discharge port 144 can be adjusted by adjusting the up and down position of the enclosure to better adapt to composite layers 102 of different thicknesses.

[0040] An upper pressing mechanism 4 is arranged on a side of the material storage mechanism 14 away from the composite layer conveyor belt 13, and the upper pressing mechanism 4 is used to grab the composite layer 102 and drive the composite layer 102 to press downward;

[0041] The upper pressing mechanism 4 includes an upper lifting structure 41, an upper negative pressure adsorption plate 42 for adsorbing the composite layer 102, and a supporting mechanism 43 for supporting the composite layer 102. In this embodiment, the upper lifting structure 41 and the lower lifting mechanism described below both use lifting cylinders, and the bottom of the upper lifting structure 41 is fixedly connected to the upper negative pressure adsorption plate 42. A plurality of negative pressure suction cups 421 are evenly distributed at the bottom of the upper negative pressure adsorption plate 42. The upper negative pressure adsorption plate 42 is provided with a pipeline for connecting the negative pressure suction cups 421, and the pipeline is connected to an external air source device;

[0042] The support mechanism 43 includes two side mounting plates 431 spaced apart in the front-to-back direction. A positioning block can be set at the right end of the side mounting plate 431 to position the composite layer 102. A support plate 432 is provided at the bottom of the side mounting plate 431.

The support plate 432 has a supporting position and an avoidance position in its telescopic stroke. The support plate 432 in the supporting position extends to the inner side of the side mounting plate 431 to support the composite layer 102. The support plate 432 in the avoidance position shrinks to the bottom of the side mounting plate 431 to form an avoidance for the composite layer 102 to pass through.

[0043] The middle layer conveyor belt 2 is arranged below the first surface layer pressing device 1. The middle layer conveyor belt 2 is used to convey the middle layer 101. The middle layer conveyor belt 2 is provided with a clamping and limiting structure and a photoelectric sensor. When the photoelectric sensor senses the middle layer 101, the clamping and limiting structure clamps the front and rear sides of the middle layer 101 to position the middle layer 101 in the left and right directions. After clamping, the middle layer 101 is positioned in the front and rear directions. The clamping and limiting structure and the photoelectric sensor are both prior arts, and their structures and principles are not described in detail here.

[0044] The middle layer glue coating roller group 3 is arranged at the discharge end of the middle layer conveyor belt 2, and the middle layer glue coating roller group 3 includes two glue coating rollers spaced apart in the up-down direction to coat glue on the upper and lower surfaces of the middle layer 101 at the same time;

[0045] The clamping conveyor belt 5 is arranged on the side of the middle layer glue coating roller group 3 away from the middle layer conveyor belt 2. The clamping conveyor belt 5 conveys the middle layer 101 by clamping the middle layer 101 sideways to prevent the clamping conveyor belt 5 from being contaminated with glue. The clamping conveyor belt 5 includes two vertical conveyor belts 51 spaced apart in the front-to-back direction. The vertical conveyor belts 51 are integrally formed with anti-slip protrusions to prevent the middle layer 101 from falling off. The middle layer 101 of the ultra-high strength specialty paper is mostly honeycomb paperboard or other relatively high strength plates, which generally have the characteristics of high strength and light weight, so it can be transported by side clamping.

[0046] The discharge conveyor belt 7 is arranged on the side of the clamping conveyor belt 5 away from the glue coating roller. The discharge conveyor belt 7 is used to discharge the ultra-high strength special paper after pressing. In this embodiment, a secondary pressing roller 6 is also provided between the clamping conveyor belt 5 and the discharge conveyor belt 7 to improve the bonding effect of the ultra-high strength special paper.

[0047] The second surface layer pressing device 9 is arranged below the middle layer conveyor belt 2, and the structure of the second surface layer pressing device 9 is the same as that of the first surface layer pressing device 1; it should be noted that in order to shorten the lifting and lowering stroke required for the lower pressing mechanism 8, the distribution of the guide rollers 112 of the second surface layer pressing device 9 is different from the distribution of the guide rollers 112 of the first surface layer pressing device 1.

[0048] A lower pressing mechanism 8 is arranged at the discharge end of the second surface layer pressing device 9, and the lower pressing mechanism 8 is located below the clamping conveyor belt 5. The upper pressing mechanism 4, the clamping conveyor belt 5 and the lower pressing mechanism 8 correspond to each other in the up-down direction;

[0049] The lower pressing mechanism 8 includes a lower lifting structure 82 and a lower negative pressure adsorption plate 81 installed on the top of the lower lifting structure 82. The lower negative pressure adsorption plate 81 has the same basic structure as the upper negative pressure adsorption plate 42. The right end of the lower negative pressure adsorption plate 81 is provided with a positioning block for positioning the composite plate.

[0050] Working principle: Before production, the surface layer roll and the fiber layer roll are installed on the corresponding raw material barrel 111;

[0051] After starting, the surface layer pressing mechanism 11 of the first surface layer pressing device 1 continuously presses the surface layer and the fiber layer to form a composite layer 102. After the cutting mechanism 12 cuts the composite layer into a set size, it is discharged into the storage mechanism 14 through the composite layer conveyor belt 13. Then, the discharge roller 143 is started to discharge the bottom composite layer 102 onto the support mechanism 43, and the upper lifting structure 41 descends to grab and adsorb the composite layer 102 through the upper negative pressure adsorption plate 42.

[0052] The process steps of the second surface layer pressing device 9 are basically the same as those described above, until the lower negative pressure adsorption plate 81 adsorbs the composite layer 102;

[0053] When the middle layer 101 moves to the right end of the middle layer conveyor belt 2, the photoelectric sensor triggers the clamping limit structure, and after positioning, the clamping limit structure releases the limit, and the middle layer 101 passes through the middle layer glue coating roller group 3 and enters the clamping conveyor belt 5;

[0054] The above steps are performed simultaneously, and then the support plate 432 shrinks to make way for the composite layer 102, the upper lifting structure 41 drives the upper negative pressure adsorption plate 42 to move downward, and the lower lifting structure 82 drives the lower negative pressure adsorption plate 81 to move upward, until the upper and lower composite layers 102 are attached to the upper and lower surfaces of the middle layer 101, and the pressing is completed;

[0055] The finally formed ultra-high strength special paper is pressed twice by the secondary pressing roller 6 and then discharged through the discharge conveyor belt 7.

[0056] The basic principles, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements shall fall within the scope of the utility model to be protected.
