Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard production technology, and in particular to an environmentally friendly corrugated cardboard composite device. Background Technology

[0002] Corrugated board lamination is a process of bonding multiple layers of paperboard (usually face paper, core paper and liner paper) together with adhesives to produce corrugated board with specific strength, cushioning properties and appearance. In the process of corrugated board lamination, adhesive needs to be applied to the corrugations in order to bond the face paper and liner paper to the core paper. The adhesive application methods usually include roller coating, spraying and brushing, etc.

[0003] Chinese Patent Publication No. CN217170016U discloses a multi-layer composite device for corrugated cardboard production, including a corrugated unwinding assembly, a corrugated forming assembly, a first drying assembly, a gluing assembly, a second drying assembly, a first face paper feeding assembly, a second face paper feeding assembly, and a roll forming assembly. The corrugated unwinding assembly is used to unwind the corrugated paper sequentially through the corrugated forming assembly, the first drying assembly, the gluing assembly, the second drying assembly, and the roll forming assembly. The first face paper feeding assembly and the second face paper feeding assembly are located on the upper and lower sides of the second drying assembly, respectively. This utility model forms the corrugated paper by setting the corrugated forming assembly, and after forming, it is dried once and then glued. After the glue is applied, it is dried a second time, and the semi-dry glue is rolled with the face paper on both sides to form a high composite precision.

[0004] The above-mentioned technology uses drying to shape the corrugated paper after it has been pressed by forming rollers. However, the corrugated paper is subjected to pressure for a short time, and the paperboard is very easy to separate before the glue has completely solidified. This seriously affects the forming quality of the corrugated paperboard. Therefore, this utility model discloses an environmentally friendly corrugated paperboard composite device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly corrugated cardboard laminating device to solve the problem mentioned in the background art that the corrugated cardboard is subjected to pressure for a short time in the traditional corrugated cardboard laminating and shaping process, and the cardboard is very easy to separate before the glue is completely solidified, which seriously affects the quality of corrugated cardboard forming.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems:

[0007] An environmentally friendly corrugated cardboard composite device includes a frame, in which a first guide roller group, a second guide roller group, an adhesive coating assembly, a conveying assembly, and a guide plate are installed. The first guide roller group, the adhesive coating assembly, the conveying assembly, and the guide plate are arranged sequentially. A second guide roller group is provided on each side of the first guide roller group, and a guide plate is provided on each side of the conveying assembly. A gap is formed between the two guide plates to guide multiple layers of cardboard through.

[0008] The gap between the two guide plates gradually narrows along the paperboard conveying direction, and the guide plates have an internal heating layer.

[0009] As a further embodiment of this utility model, one end of the guide plate facing the conveying assembly gradually deviates away from the side away from the cardboard, while the other end of the guide plate is parallel to the cardboard conveying direction.

[0010] As a further embodiment of this utility model, the guide plate also includes a heat insulation layer and a heat conduction layer located on both sides of the heating layer. The heat insulation layer is located on the side of the heating layer away from the cardboard. The heat insulation layer is made of ceramic material, and the heat conduction layer is made of stainless steel material. The edges of the heat insulation layer and the heat conduction layer are connected.

[0011] As a further embodiment of this utility model, the adhesive application assembly includes a pressure pipe fixedly embedded between the two side walls of the frame. One end of the pressure pipe extending out of the frame is fixedly connected to a flange plate, and multiple nozzles are fixedly embedded on the adjacent side of the two pressure pipes.

[0012] As a further embodiment of this utility model, the conveying assembly includes a central shaft rotatably connected between the two side walls of the frame, a transmission box fixedly connected to the outer wall of one side of the frame, and a drive motor fixedly connected to one side of the transmission box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model discloses an environmentally friendly corrugated cardboard composite device. The device drives the pressure roller to rotate via a drive motor. The corrugated cardboard surface layer slides along the guide plate and enters the gap between the guide plates by relying on friction. The width of the gap between the guide plates gradually narrows along the cardboard conveying direction, which can gradually press the multiple layers of cardboard together and convey them forward, ensuring that the surface layer and the core layer are tightly bonded. The various parts of the multiple layers of cardboard gradually deform and bond together, avoiding problems such as weak adhesion, and realizing continuous production.

[0017] This utility model discloses an environmentally friendly corrugated cardboard composite device. During the corrugated cardboard composite transport process, glue is evenly sprayed onto the surface of the corrugated cardboard core layer through a nozzle. The electric heating layer built into the guide plate is energized and heats up, which can preheat the surface layer and heat the corrugated cardboard, so that the adhesive in the corrugated cardboard solidifies and forms in the gap between the guide plates.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Please see Figure 1-6 This utility model provides an environmentally friendly corrugated cardboard composite device, including a frame 1. The frame 1 is equipped with a guide roller group 1 2, a guide roller group 2 3, an adhesive coating assembly 4, a conveying assembly 5, and a guide plate 6. The adhesive coating assembly 4 includes a pressure pipe 41 fixedly embedded between the two side walls of the frame 1. One end of the pressure pipe 41 that extends out of the frame 1 is fixedly connected to a flange plate 42, and multiple nozzles 43 are fixedly embedded on the adjacent side of the two pressure pipes 41.

[0029] Specifically, glue or other adhesive substances are delivered to the pressure tube 41 through external pipes or equipment. The pressure inside the pressure tube 41 pushes the glue towards the nozzle 43. After the glue reaches the nozzle 43, it is sprayed out in the form of mist or fine stream through the nozzle orifice of the nozzle 43, which can achieve large-area glue coating operation. Preferably, the nozzles 43 are evenly distributed, and there is a certain glue coating overlap between adjacent nozzles 43 to ensure that all parts of the corrugated cardboard core layer can be completely coated.

[0030] Furthermore, the guide roller group 2, the glue application assembly 4, the conveying assembly 5, and the guide plate 6 are arranged sequentially. The conveying assembly 5 includes a central shaft 51 rotatably connected between the two side walls of the frame 1, a transmission box 52 fixedly connected to the outer wall of one side of the frame 1, and a drive motor 53 fixedly connected to one side of the transmission box 52. A pressure roller 511 is fixedly sleeved on the outer side of the middle part of the central shaft 51. Two transmission gears 521 are provided in the transmission box 52. The two transmission gears 521 are meshed and connected. One end of the central shaft 51 passes through the frame 1 and the transmission box 52 and is fixedly connected to the adjacent transmission gear 521. The output end of the drive motor 53 passes through the transmission box 52 and is fixedly connected to one of the transmission gears 521.

[0031] Specifically, the drive motor 53 drives two transmission gears 521 to mesh and transmit power. The two transmission gears 521 drive two pressure rollers 511 to rotate in opposite directions. The pressure rollers 511 can drive the corrugated cardboard surface layer to slide against the guide plate 6 by friction. It is worth noting that the gap between the pressure rollers 511 and the guide plate 6 is slightly smaller than the thickness of the corrugated cardboard surface layer to ensure that there is sufficient friction between the pressure rollers 511 and the guide plate 6.

[0032] Furthermore, a guide roller group 2 is provided on each side of the guide roller group 1 2, and the guide roller group 1 2 includes at least two first guide rollers 21, which are rotatably connected between the two side walls of the frame 1.

[0033] Specifically, two first guide rollers 21 are respectively disposed on the upper and lower sides of the corrugated cardboard core layer, which plays the role of clamping the corrugated cardboard core layer, so that the corrugated cardboard core layer will not come into premature contact with the corrugated cardboard surface layer on the upper and lower sides. At the same time, the rotatable characteristic of the first guide rollers 21 effectively reduces the resistance of the corrugated cardboard core layer passing through. Optionally, multiple pairs of first guide rollers 21 improve the support effect, especially suitable for the soft corrugated cardboard core layer, which can prevent the corrugated cardboard core layer from being excessively deformed and damaged in a long transmission path.

[0034] Furthermore, the guide roller assembly 3 includes at least one second guide roller 31, which is rotatably connected between the two side walls of the frame 1;

[0035] Specifically, the second guide roller 31 plays the role of guiding the bending and turning of the corrugated cardboard surface layer, and the rotatable characteristic of the second guide roller 31 effectively reduces the resistance of the corrugated cardboard surface layer passing through. It is worth noting that the number of second guide rollers 31 needs to be determined according to the structure of the production workshop. When the paper roll is far away, multiple second guide rollers 31 may be needed to cooperate in guiding. This application will not elaborate on this.

[0036] Furthermore, a guide plate 6 is provided on each side of the conveying assembly 5, and a gap is formed between the two guide plates 6 for guiding multiple layers of cardboard through. The width of the gap between the two guide plates 6 gradually narrows along the cardboard conveying direction. The end of the guide plate 6 facing the conveying assembly 5 gradually deviates away from the side away from the cardboard, and the other end of the guide plate 6 is parallel to the cardboard conveying direction.

[0037] Specifically, the deviation of the guide plate 6 from the end facing the conveying component 5 is gradual, rather than a sudden change in angle. This causes the guide plate 6 to have a certain inclined shape or curved structure near the conveying component 5, which guides the cardboard to gradually adjust its position or direction before entering the conveying component 5, thus avoiding damage to the cardboard. It is worth noting that the end of the guide plate 6 facing the conveying component 5 contacts the surface layer of the corrugated cardboard first, which has a preheating effect to ensure that the surface layer of the corrugated cardboard can solidify quickly after contact with the glue. The end of the guide plate 6 away from the conveying component 5 has a flat structure, which allows the corrugated cardboard to be continuously heated during the transmission process. It is also worth noting that the gap width between the flat structures of the two guide plates 6 is slightly smaller than the design thickness of the corrugated cardboard, which ensures the bonding effect between the cardboard and the forming quality of the corrugated cardboard.

[0038] Furthermore, the guide plate 6 has an internal heating layer 61;

[0039] Specifically, the heating layer 61 has a built-in heating wire. When the heating wire is energized, it generates heat and plays a heating role. It is worth noting that a temperature sensor can also be installed in the heating layer 61. The temperature sensor transmits the temperature information of the heating layer 61 to the control terminal. When the temperature of the heating layer 61 exceeds the preset value, the control terminal controls the heating layer 61 to cut off the power. When the temperature of the heating layer 61 is lower than the preset value, the control terminal controls the heating layer 61 to re-energize, which can maintain the heating layer 61 at a constant temperature to avoid overheating damage to the cardboard and ensure the quality of the corrugated cardboard.

[0040] Furthermore, the guide plate 6 also includes a heat insulation layer 62 and a heat conduction layer 63 located on both sides of the heating layer 61. The heat insulation layer 62 is located on the side of the heating layer 61 away from the cardboard. The heat insulation layer 62 is made of ceramic material, and the heat conduction layer 63 is made of stainless steel material. The edges of the heat insulation layer 62 and the heat conduction layer 63 are connected.

[0041] Specifically, the heat-conducting layer 63 evenly transfers the heat from the heating layer 61 to the surface of the cardboard, ensuring that the cardboard is heated evenly. The heat-conducting layer 63, made of stainless steel, reduces frictional resistance. The insulation layer 62 is located on the back of the heating layer 61, preventing heat from escaping to the outside of the equipment and improving the efficiency of heat utilization. Through the synergistic effect of the insulation layer 62 and the heat-conducting layer 63, the heat is mainly concentrated on one side of the cardboard, reducing energy waste, while protecting other parts of the equipment from high temperatures.

[0042] Working principle:

[0043] When using, such as Figure 2As shown, the drive motor 53 drives two transmission gears 521 to mesh and transmit power. The two transmission gears 521 drive two pressure rollers 511 to rotate in opposite directions. The pressure rollers 511 rely on friction to drive the corrugated cardboard surface layer to slide against the heat-conducting layer 63 of the guide plate 6 until the corrugated cardboard surface layer enters the narrowest part of the gap between the two guide plates 6 and presses against the corrugated cardboard core layer. The surface layer and the core layer are squeezed at the gap to form corrugated cardboard and are transported forward. At the same time, the electric heating layer 61 is energized and heats up, which can preheat the surface layer and heat the corrugated cardboard, so that the adhesive between the surface layer and the core layer can be quickly solidified and formed. During this process, glue is pumped into the pressure pipe 41 and sprayed out from the nozzle 43, which can be evenly sprayed on the surface of the core layer that is being dragged forward, so that the corrugated cardboard can be produced continuously.
