Description

Technical Field

[0001] The present application relates to the technical field of corrugated paper production, and in particular to a continuous gluing and pressing device for environmentally friendly corrugated paper and a method thereof. Background Art

[0002] In the field of corrugated paper production, gluing and laminating are the core links that determine the quality and environmental performance of paperboard. Traditional gluing processes generally use solvent-based glue, which has problems such as volatile organic compounds, high emissions, serious glue waste, and unstable bonding strength. Early nozzle-type gluing devices were unable to accurately control the amount of glue, resulting in the non-bonded areas of the corrugated core paper being sprayed, causing glue waste. At the same time, uncured glue easily drips and contaminates the equipment. In addition, the traditional lamination process relies on high temperature and high pressure, which consumes a lot of energy and can easily cause the paperboard to deform. In the prior art, relevant technologies for corrugated paper production can be referred to Chinese patent publication number CN116945692A, which discloses a corrugated cardboard box gluing device, including a placement table, a gluing roller, and a dust removal assembly. A mounting slot is provided above the placement table, and a reel pressing assembly for stacking and gluing the corrugated cardboard boxes is provided above the placement table. The gluing roller is rotatably mounted on a bracket and is located on one side of the mounting slot. The bracket is connected to the adjustment assembly, and one end of the gluing roller is connected to the drive assembly. By adding the gluing roller, the dust removal assembly, the dust reduction assembly, and the driving assembly used in conjunction with each other, the corrugated cardboard box placed on the placement table can be pushed to the bottom of the gluing roller by first and second conveyor rollers for gluing, while the dust and foreign particles on the surface are adsorbed and removed by a dust suction pipe. The solution solves the problem of dust removal during the pushing process, reduces dust and foreign particles on the surface of the corrugated cardboard box, effectively increases the adhesion area between two corrugated cardboard boxes, improves the strength of the adhesion of the corrugated cardboard boxes, and improves the firmness of the corrugated cardboard boxes.

[0003] In the process of implementing this application, the inventors discovered that the prior art has the following problems: During the production of corrugated paper, the glue overflowing from the edges of the corrugated paper after lamination during the pressing process is difficult to recover, which will directly lead to the waste of glue. The glue remaining at the edges of the corrugated paper will also fall off during use, resulting in contamination at the glue attachment point. At the same time, in order to ensure the bonding effect, colloid will also be applied on the corrugated paper. This coating method will also cause the colloid to remain at the bonding point of the corrugated paper and not participate in the bonding, thereby resulting in the waste of colloid. Summary of the Invention

[0004] The purpose of this application is to provide an environmentally friendly corrugated paper continuous gluing and pressing device and method.

[0005] The present application provides an environmentally friendly corrugated paper continuous gluing and laminating device and method thereof, which adopts the following technical solutions: A continuous gluing and pressing device for environmentally friendly corrugated paper includes a frame and a gluing mechanism. A mounting bracket is installed above the frame, and a first conveying platform and a third conveying platform are respectively installed on both sides of the mounting bracket. The second conveying platform is installed on the side of the first conveying platform by bolts, and a paper changer is installed below the third conveying platform. The frame includes a gluing mechanism, and a first paper feeder and a second paper feeder are sequentially arranged on the sides of the gluing mechanism. The gluing mechanism includes a double-coating component and a gluing component.

[0006] By adopting the above technical solution, the mounting bracket is used to install the first conveyor platform and the second conveyor platform by bolts, wherein the first conveyor platform, the second conveyor platform and the third conveyor platform are used to convey paper, and then the paper is conveyed to the gluing mechanism in the frame by the paper changer and the corresponding first paper feeder and the second paper feeder. The paper changer and the first paper feeder and the second paper feeder are all existing technologies, so they are not discussed again. At this time, when the paper is conveyed and enters the interior of the gluing mechanism, the double coating component and the gluing component are used to coat the paper twice, and through different gluing methods, while reducing the amount of glue used, it also reduces the amount of additional colloid coating required to avoid degumming. The gluing mechanism includes a first pressing roller, a heating pressing wheel is attached below the first pressing roller, a gluing box is arranged below the heating pressing wheel, and a double-coating component is arranged between the heating pressing wheel and the gluing box.

[0007] By adopting the above technical solution, the first pressing roller presses the paper above the heating pressing wheel, and the electric heating wire inside the heating pressing wheel heats the outer wall of the wheel body. At this time, the paper is softened by the adhesion between the paper and the heating pressing wheel, and the adhesion of the paper to the colloid is facilitated.

[0008] The gluing mechanism further includes a groove pressing roller, a groove pressing main roller is attached to the upper side of the groove pressing roller, a guide roller is attached to the side of the groove pressing main roller, and a heating contact platform is provided below the groove pressing main roller.

[0009] By adopting the above technical solution, the groove pressing wheel is used to contact the glue coating roller in the glue coating box. At this time, the protrusion on the groove pressing wheel contacts the glue coating roller, and the colloid is attached to the protrusion. During the rotation of the groove pressing wheel, the colloid on the protrusion of the groove pressing wheel continuously adheres the colloid to the protrusion of the indentation, thereby reducing the amount of colloid used.

[0010] The gluing mechanism further includes a gluing assembly, a first pressing roller is provided on the side of the gluing assembly, and a second pressing roller is provided below the first pressing roller.

[0011] By adopting the above technical solution, after the semi-finished paper is bonded, the indented paper of the semi-finished paper and the gluing component are processed again, and the glue is re-attached and squeezed by the first pressing roller and the second pressing roller to make the glue bonded, thereby facilitating the formation of corrugated paper.

[0012] The glue coating box comprises a glue placement box, a glue squeezing roller and a glue coating roller. The glue coating roller is arranged above the groove of the glue placement box, and the glue squeezing roller is arranged on the other side of the glue coating roller.

[0013] By adopting the above technical solution, the glue placement box is used to place glue, and the glue coating roller is driven by a motor, so that the bottom of the glue coating roller is in contact with the glue, and the glue coating roller divides the glue into two parts during the gluing process, and adheres them to the bonding points of the two sheets of paper respectively. By reducing the amount of glue contacted by each sheet of paper by half, the solidification of the glue is facilitated, and the glue on the paper is quickly solidified and adhered during the bonding process, so as to reduce the amount of glue used and reduce the risk of the glue applied slipping on the paper, causing the glue to shift.

[0014] The heating contact table includes a grooved conveyor roller, both ends of which are movably connected to a first supporting bracket, the other side of the two groups of the first supporting brackets are fixed with a heating table by bolts, the other side of the heating table is fixed with a second supporting bracket by bolts, the inner side of the second supporting bracket is movably connected to a guide conveyor roller, and a heating groove is provided on the heating table.

[0015] By adopting the above technical solution, the function of the heated contact table is the same as that of the heated pressure wheel, but it guides the conveying roller to convey the paper. At this time, the paper is above the heating table, and in the process of the paper moving above the heating table, the high temperature generated by the electric heating wire in the heating tank is processed with the paper, softening the paper, and allowing the softened paper to be bent.

[0016] The double-coating assembly includes a laminating roller, and supporting and fixing frames are provided on both sides of the double-coating assembly. A movable groove is opened on the inner wall of the supporting and fixing frame, and a driving bracket is installed on both sides of the laminating roller. The other end of the driving bracket is movably connected in the movable groove, and the driving motor located on the other side of the supporting and fixing frame drives the driving bracket to rotate along the axis to cause the laminating roller to rotate axially.

[0017] By adopting the above technical solution, the laminating roller can drive the distance between the paper and the gluing main machine to be adjusted. For paper of different thicknesses, the contact surface between the paper and the roller can be changed to correct the softening degree of the paper. The laminating roller connected to the driving bracket can be adjusted by the motor, and the conveying length of the paper can be adjusted.

[0018] The glue coating assembly includes a roller body, a liquid injection port is provided on the side of the roller body, a liquid storage tank is provided inside the roller body, and a seepage groove is provided on the outer diameter surface of the roller body. The inside of the seepage groove is filled with adsorption cotton, a collection box is provided below the roller body, and a delivery pipe is inserted above the inner wall of the glue coating box. The other end of the delivery pipe away from the glue coating box is sealed with the liquid injection port of the roller body through a bearing.

[0019] By adopting the above technical solution, the liquid storage tank provided in the roller body is used to store the colloid, and in the process of the roller body driving the semi-finished paper to move, the colloid is caused to flow continuously in the roller body, and the colloid in the liquid storage tank is at the bottom, which will cause the colloid to penetrate into the seepage tank and cause the adsorption cotton to adsorb the colloid. At this time, in the process of the movement of the semi-finished paper, the protrusions of the paper will directly enter the inside of the seepage tank and contact with the adsorption cotton, so that the protrusions of the paper contacted by the adsorption cotton will squeeze out the colloid in the adsorption cotton, and adhere to the protrusions of the paper and connect.

[0020] The gluing mechanism includes a supporting side frame and a supporting fixed frame. The side of the supporting side frame is installed with a supporting fixed frame by bolts. The first pressing roller, the heating pressing wheel, the gluing box, the double coating assembly, the gluing assembly, the first pressing roller, the second pressing roller, the guide conveying roller, the grooving roller and the two ends of the laminating roller are movably connected to the corresponding supporting side frame and the supporting fixed frame through a rotating shaft and a bearing. A climbing frame is provided on the side of the first conveying platform.

[0021] A method for continuous gluing and laminating of environmentally friendly corrugated paper, comprising the following steps: Step 1: First, the paper changer, the first paper feeder and the second paper feeder convey the paper into the interior of the gluing structure. At this time, the paper conveyed by the paper changer passes through the third conveying platform and contacts the first pressing roller. Then the paper enters the bonding end of the first pressing roller and the heated pressing wheel, is squeezed and conveyed to the grooving roller on the double-coating assembly, and continues to be conveyed to the bonding surface between the heated pressing wheel and the grooving roller, and enters. Before the paper contacts the bonding part of the heated pressing wheel and the grooving roller, the grooving roller completes the gluing process on other papers and re-contacts the paper with the remaining glue on its raised part, and adjusts the diameter setting of the corresponding roller so that the corresponding gluing positions coincide with each other. Therefore, glue is provided at the bonding part on both sheets of paper, and the bonding of the papers is completed under the contact of the heated pressing wheel and the paper. Step 2: Then the first paper feeder is driven and conveys the paper into the gluing mechanism in the machine body. At this time, the conveyed paper enters the guide conveying roller arranged on the heated contact table. At this time, the first contact roller and the second contact roller arranged on the guide conveying roller squeeze and convey the conveyed paper, and convey the paper and drive the heating table on the heated contact table. After the paper is softened by the heating table, it enters the interior of the groove conveying roller. At this time, the groove conveying roller and the groove pressing roller squeeze the conveyed paper and form a dent, and continue to convey the conveyed dented paper forward. In the process of conveying, the glue coating roller in the glue coating box wraps the colloid, and the adhered colloid contacts the groove pressing roller, and applies the colloid to the convex part of the dent; Step three: After the concave paper and the glued paper are glued together, the glued paper is conveyed to the first conveyor platform, and during the conveying process, the roller of the glue coating component supports and contacts the semi-finished paper being conveyed, and because the concave paper of the semi-finished paper being conveyed is fitted with the seepage groove of the glue coating component, while increasing the friction, the other side of the concave paper is raised inside the seepage groove of the glue coating component and contacts the adsorption cotton, so that the glue in the adsorption cotton is adhered to the raised contact surface of the concave paper. At this time, the second paper feeder conveys the paper to the first conveyor platform, supported by the second pressing roller, and makes the semi-finished paper with the other side glued contact with the paper conveyed by the second pressing roller, and at the same time of fitting, the first pressing roller and the second pressing roller squeeze the contacted paper and accelerate the bonding to complete the production of corrugated paper.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This device utilizes the synergistic effect of a dual coating assembly and a gluing assembly to create a zoned gluing system. The glue squeeze roller and gluing roller in the gluing box work together to evenly divide the glue applied once into two parts, which are then applied to the joining points of the two sheets of paper. This reduces glue usage compared to single-sided gluing. Furthermore, the raised structure of the grooved roller applies glue only to the raised areas of the paper's indentations, preventing glue from being wasted in non-bonded areas. 2. The gluing component is designed with a seepage groove and adsorption cotton, and the gluing method is contact penetration, so that the colloid is only squeezed out when the paper protrusion is inserted, achieving adhesion of the glue. This can reduce the colloid consumption in the gluing process, reduce production costs, and reduce the emission of volatile organic compounds during the colloid curing process, which is in line with environmental protection needs.

Before the paper contacts the bonding area between the heated pressing wheel 13 and the grooving roller 27, the grooving roller 16 completes the gluing process on other papers and re-contacts the paper with the remaining glue at its protrusion, and adjusts the diameter setting of the corresponding rollers so that the corresponding gluing positions coincide with each other, so that glue is provided at the bonding area on both sheets of paper, and the bonding of the papers is completed under the contact of the heated pressing wheel 13 with the paper. Then the first paper feeder 8 is driven and conveys the paper into the gluing mechanism 10 in the machine body. At this time, the conveyed paper enters the guide conveying roller 24 provided on the heating contact table 18. At this time, the first contact roller 2401 and the second contact roller 2402 provided on the guide conveying roller 24 squeeze and convey the conveyed paper, and convey the paper and drive the heating table 23 on the heating contact table 18. After being softened by the heating table 23, the paper enters the interior of the groove conveying roller 22. At this time, the groove conveying roller 22 and the groove pressing roller 27 squeeze the conveyed paper and form a dent, and continue to convey the conveyed dented paper forward. In the process of conveying, the glue coating roller 1403 in the glue coating box 14 wraps the glue, and the adhered glue contacts the groove pressing roller 16, and applies the glue to the raised part of the dent. Then, after the concave paper and the glued paper are glued together, the glued paper is conveyed to the first conveyor platform 2, and during the conveying process, the roller body 1901 of the glue coating component 19 supports and contacts the semi-finished paper being conveyed, and because the concave paper of the semi-finished paper being conveyed is fitted with the seepage groove 33 of the glue coating component 19, while increasing the friction, the other side of the concave paper is raised inside the seepage groove 33 of the glue coating component 19 and contacts the adsorption cotton 34, so that the glue in the adsorption cotton 34 is adhered to the raised contact surface of the concave paper. At this time, the second paper feeder 9 conveys the paper to the first conveyor platform 2, supported by the second pressing roller 21, and makes the semi-finished paper with the other side glued contact with the paper conveyed by the second pressing roller 21. At the same time of fitting, the first pressing roller 20 and the second pressing roller 21 squeeze the contacted paper and accelerate the bonding to complete the production of corrugated paper.

10. A method for continuous gluing and laminating environmentally friendly corrugated paper, using the device for continuous gluing and laminating environmentally friendly corrugated paper according to any one of claims 1 to 9, characterized in that: The continuous gluing and laminating method comprises the following steps: Step 1: First, the paper changer (6), the first paper feeder (8) and the second paper feeder (9) convey the paper into the interior of the gluing structure. At this time, the paper conveyed by the paper changer (6) passes through the third conveying platform (5) and contacts the first pressing roller (12). Then, the paper enters the bonding end of the first pressing roller (12) and the heated pressing wheel (13), is squeezed and conveyed to the groove pressing roller (16) on the double coating assembly (15), and continues to the bonding surface between the heated pressing wheel (13) and the groove pressing roller (27). The paper is transported and enters the heating roller (13) and the groove roller (27) before the paper contacts the bonding area. At this time, the groove roller (16) completes the gluing process on the other paper and re-contacts the paper with the remaining glue at the raised part. By adjusting the diameter of the corresponding roller, the corresponding gluing positions are overlapped. Therefore, the two papers are provided with glue at the bonding area, and the bonding of the paper is completed under the contact of the heating roller (13) and the paper. Step 2: Then the first paper feeder (8) is driven and the paper is conveyed into the gluing mechanism (10) in the machine body. At this time, the conveyed paper enters the guide conveying roller (24) provided on the heating contact table (18). At this time, the first contact roller (2401) and the second contact roller (2402) provided on the guide conveying roller (24) squeeze and convey the conveyed paper, and convey the paper and drive the heating table (23) on the heating contact table (18). After the paper is softened by the heating table (23), it enters the interior of the groove conveying roller (22). At this time, the groove conveying roller (22) and the groove pressing roller (27) squeeze the conveyed paper and form a dent, and the conveyed dented paper continues to be conveyed forward. During the conveying process, the glue coating roller (1403) in the glue coating box (14) wraps the glue, and the glued glue contacts the groove pressing roller (16), and the glue is applied to the convex part of the dent. Step 3: After the concave paper and the glued paper are bonded together, the bonded paper is transported to the first conveying platform (2). During the transporting process, the roller body (1901) of the glue coating component (19) supports and contacts the transported semi-finished paper. Because the concave paper of the transported semi-finished paper is fitted with the seepage groove (33) of the glue coating component (19), while increasing the friction, the other side of the concave paper is raised inside the seepage groove (33) of the glue coating component (19), and The paper contacts the adsorption cotton (34), so that the glue in the adsorption cotton (34) adheres to the contact surface of the convex part of the concave paper. At this time, the second paper feeder (9) transports the paper to the first conveying platform (2), supported by the second pressing roller (21), and makes the semi-finished paper with the glue coated on the other side contact with the paper conveyed by the second pressing roller (21). At the same time, the first pressing roller (20) and the second pressing roller (21) squeeze the contacted paper and accelerate the bonding to complete the production of corrugated paper.
