[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Corrugated cardboard is a multi-layered adhesive, mainly composed of face paper, liner paper, core paper, and corrugated paper.

[0023] Manufacturing process

[0024] Raw paper preparation: First, select suitable paper as raw material for face paper, liner paper, core paper and corrugated paper. The quality, weight and other parameters of these papers will be selected according to the use of corrugated cardboard. For example, for corrugated cardboard used to package heavier items, the face paper and liner paper may be selected with a larger weight and higher strength.

[0025] Corrugated forming: Corrugated base paper is processed into corrugated paper in a wavy shape by a corrugating machine. The corrugating machine mainly consists of a pair of corrugated rollers facing each other. The surface of the corrugated rollers has special toothed shape. When the base paper passes through the corrugated rollers, it is pressed into a corrugated shape. At the same time, the paper fibers are softened by heating, which makes it easier to form.

[0026] Gluing and bonding: After the corrugated paper is formed, glue needs to be applied to the peaks and valleys of its wavy shape. Then, the core paper, face paper, and liner paper are bonded together in sequence. The quality and amount of glue have an important impact on the quality of the corrugated paperboard. Too little glue will cause the paperboard to delaminate, while too much glue may cause the paperboard to deform.

[0027] Drying and Cutting: After lamination, the corrugated cardboard needs to be dried to cure the glue and enhance the strength of the cardboard. After drying, the corrugated cardboard is cut to the required size to become the final product.

[0028] Performance characteristics

[0029] Excellent cushioning performance: Due to the wavy shape of corrugated paper, corrugated cardboard can effectively absorb and disperse impact forces, providing good cushioning protection for packaged items. For example, during transportation, when a package is hit or dropped, corrugated cardboard can cushion the impact force and reduce damage to the internal products.

[0030] High strength and stiffness: Through reasonable paper combination and structural design, corrugated cardboard can have high compressive strength and stiffness, and can withstand the weight of items without deformation. For example, when stacking multiple cartons containing goods, the strength of corrugated cardboard can ensure that the cartons will not easily collapse under pressure.

[0031] Lightweight and low cost: Compared to other packaging materials such as wood and metal, corrugated cardboard is lighter, which not only makes it easier to transport and handle, but also reduces transportation costs. At the same time, the raw material cost of corrugated cardboard is relatively low, and the manufacturing process is relatively mature. Therefore, its overall cost is low, making it an economical packaging material.

[0032] Easy to process and print: Corrugated cardboard can be easily cut, folded, and slotted to make packaging containers of various shapes. Its surface can also be printed to display product information, brand logos, and other content, playing a certain promotional role.

[0033] Application areas

[0034] Packaging industry: This is the main application area for corrugated cardboard. It can be used to package various products, such as electronic products, food, daily necessities, furniture, etc. For example, in electronic product packaging, corrugated cardboard can provide good protection for delicate electronic equipment; in food packaging, corrugated cardboard can play the roles of isolation, cushioning and display.

[0035] Transportation industry: In the logistics and transportation process, packaging boxes, pallets and other items made of corrugated cardboard are indispensable. They can facilitate the classification, stacking and transportation of goods, improve logistics efficiency and protect the safety of goods.

[0036] Display industry: Corrugated cardboard can be made into display racks, display boxes, etc., for product display. Its good processing performance allows for the creation of various creative display props to attract consumers' attention.

[0037] Corrugated board forming equipment is mainly used to achieve reliable forming of corrugated board.

[0038] Applications of corrugated cardboard forming equipment

[0039] Curing adhesive: In the manufacturing process of corrugated cardboard, adhesive is used to bond the face paper, liner paper, core paper, and corrugated paper together. The setting device (such as a heat setting device) can provide a suitable temperature and environment to allow the adhesive to dry and cure quickly. For example, during the heat curing process, the adhesive molecules undergo a cross-linking reaction under the action of heat energy, changing from a liquid state to a solid state, thereby firmly bonding the layers of paper together. If the adhesive is not fully cured, the corrugated cardboard is prone to delamination during subsequent processing, transportation, or use, affecting its quality and performance.

[0040] Stabilizing the corrugated cardboard structure: The structural feature of corrugated cardboard is its wavy corrugated paper. The shaping device can make this structure more stable. By applying pressure through the pressure shaping device, the wavy shape of the corrugated paper can be made more regular, and the bonding between the layers of paper can be made tighter. Taking pressure shaping as an example, appropriate pressure can make the corrugation peaks and valleys of the corrugated paper contact the adjacent paper better, reduce air gaps, and enhance the overall strength and stiffness of the cardboard.

[0041] Shaping into specific shapes: For some special-purpose corrugated cardboard, it is necessary to shape it into specific shapes. For example, in the process of making corrugated boxes, the cardboard needs to be bent and shaped into the shape of a box, or to make some creative corrugated cardboard display items, such as corrugated cardboard sculptures. Vacuum adsorption shaping devices or pressure shaping devices with molds can play a role in shaping the cardboard into the required shape according to the design requirements, so as to meet the diverse needs of products.

[0042] Purpose of corrugated cardboard shaping

[0043] Improved strength and compression resistance: After sizing, the layers of corrugated cardboard are more tightly bonded, and the shape of the corrugations is more regular. This allows the corrugated cardboard to withstand greater pressure and effectively protect the contents during packaging and transportation. For example, when stacking cartons containing goods, sizing corrugated cardboard cartons can withstand greater pressure, reducing the risk of the cartons collapsing and thus protecting the goods from damage.

[0044] Ensuring dimensional accuracy: In some automated packaging production lines, the dimensional accuracy requirements for corrugated cardboard are high. The shaping process can ensure the dimensional stability of the corrugated cardboard, such as the length, width, and thickness of the cardboard, which meet the standards. This allows for better matching with production equipment in subsequent processing stages such as printing, cutting, and folding, thereby improving production efficiency and product quality. For example, if the dimensions of the cardboard are unstable when making corrugated boxes, it may lead to problems such as uneven folding and loose joints.

[0045] Enhanced cushioning performance: A stable corrugated structure helps improve the cushioning performance of corrugated cardboard. When subjected to external impact, well-formed corrugated cardboard can better absorb and disperse the impact force. For example, during product transportation, if a collision or drop occurs, the corrugated cardboard can use its elasticity and cushioning ability to distribute the impact force throughout the cardboard structure, reducing the direct impact on the product and lowering the probability of product damage.

[0046] Improved appearance quality: The surface of the corrugated cardboard after shaping is smoother, which is very important for cardboard that needs to be printed. The smooth surface can ensure the clarity and accuracy of the printed pattern, improve the appearance quality of the product. At the same time, the regular shape of the shaped cardboard can make the appearance of the packaging container more neat and beautiful, which is conducive to the sales of the product and the enhancement of the brand image.

[0047] Corrugated board forming equipment ensures the quality and stability of corrugated board, improves production efficiency, and reduces production costs, making it an indispensable key piece of equipment in corrugated board production. However, corrugated board forming equipment often encounters some problems during actual use. Below are some common problems and their causes: 1. Poor bonding: The main causes may be excessive tension on the facing paper, high moisture content in the facing and core paper, insufficient adhesive application or poor adhesive quality, non-parallelism between the corrugating roller and the gluing roller, incorrect guide plate position or dirt, non-parallelism between the gluing roller and the floating roller, insufficient heat causing premature starch coagulation, etc. 2. Lateral downward warping: The main causes may be insufficient glue application by the gluing machine, insufficient temperature of the hot plate of the double-facer, insufficient moisture content of the single-faced corrugated board in the paper feed bridge, excessive heating by the triple preheater, excessive machine speed, insufficient running tension of the single-faced corrugated board, etc. 3. Lateral upward warping: The main causes may be excessive preheating angle of the face paper, insufficient preheating angle of the liner paper, excessive accumulation of paper feed bridges, excessive glue application on the single-facer, low machine speed, high temperature of the hot plate on the double-facer, and excessive pressure applied by the weight roller. 4. Liner paper delamination: The main causes may be substandard glue quality, insufficient glue application, insufficient heat on the corrugating and pressure rollers, insufficient pressure on the pressure rollers, and wear on the corrugating and pressure rollers. 5. Face paper delamination: The main causes may be insufficient glue application, slow dryer speed, thin glue solution, insufficient glue on the glue application rollers, insufficient temperature of the hot plate on the dryer, and insufficient drying due to excessive dryer speed.

[0048] Currently, various types of corrugated cardboard shaping devices are available on the market, designed to ensure the quality of corrugated cardboard, improve production efficiency, meet diverse packaging needs, and reduce production costs. Below is a detailed introduction to several common corrugated cardboard shaping devices: 1. Manual Corrugated Cardboard Shaping Machine: This machine fixes the moistened paper onto a mold and shapes it by manual pressing. Problems: Relatively low efficiency, heavy reliance on manual labor, and production quality may be affected by human factors. 2. Semi-Automatic Corrugated Cardboard Shaping Machine: This machine places the moistened paper on the machine and shapes it through machine pressure and timed heating. Problems: Although more efficient than manual machines, it still requires some manual operation, and production quality may be affected by wear and tear or improper adjustment of mechanical parts. 3. Fully Automatic Corrugated Cardboard Shaping Machine: This machine automatically feeds the moistened paper into the machine, where it undergoes heating, pressing, and other steps to complete the shaping and strengthening process. Problems: The high degree of automation places high demands on equipment maintenance and upkeep. If a malfunction occurs, the repair and time costs may be high. At the same time, fully automated equipment also has relatively high requirements for the quality of raw materials, otherwise it may affect the final product's finalization.

[0049] Although there are various types of corrugated cardboard forming equipment on the market, they all have their own problems. When selecting a corrugated cardboard forming equipment, the following aspects should be considered: cardboard type and load-bearing requirements, production efficiency and degree of automation, equipment performance and stability, raw material adaptability, and maintenance and cost.

[0050] Please see Figures 1-2 This utility model provides an embodiment of an environmentally friendly corrugated cardboard shaping device, including a conveying module 1, a box 2, a steam assembly, a hot pressing assembly, a door 5, a transparent glass 6, and a PLC controller 7. The conveying module 1 is used to convey corrugated cardboard. A box 2 for reducing heat loss is fixedly installed on the upper side of the conveying module 1. Guide grooves for easy entry and exit of corrugated cardboard are opened between the lower left and right ends of the box 2 and the conveying module 1. A steam assembly for spraying steam on the surface of the corrugated cardboard to increase surface humidity and recover waste heat is fixedly installed on the upper right side of the box 2. A hot pressing assembly for hot pressing, drying, and shaping the corrugated cardboard is fixedly installed on the upper left side of the box 2. A door 5 for opening and closing is provided at the front end of the box 2, corresponding to the positions of the steam assembly and the hot pressing assembly. A convenient door is embedded in the door 5. The transparent glass 6 allows observation of the internal corrugated cardboard forming process. A PLC controller 7, used to control the steam and hot-press components, is fixedly installed at the front center of the housing 2. The steam component sprays water vapor, increasing the surface humidity of the corrugated cardboard, which helps soften and bond the paper fibers, reducing cracking and deformation, and improving the cardboard's flatness. The hot-press component dries and shapes the corrugated cardboard, activating the internal fibers and making the corrugated cardboard more durable. It also smooths wrinkles on the surface, maintaining flatness and enhancing the cardboard's compressive strength. Furthermore, the drying step during hot-pressing ensures the cardboard reaches the required dryness, preventing warping and bending. Combining water vapor spraying with hot-pressing drying and shaping improves the cardboard's quality and performance.

[0051] Please see Figures 3-4In this embodiment, the steam assembly includes a steam box 301, a first conduit 302, a connecting pipe 303, a nozzle 304, a second conduit 306, a guide hopper 307, a fan 308, a water inlet pipe 309, and a first control module 310. The steam box 301 is fixedly installed at the rear end of the housing 2. A first conduit 302 for introducing steam into the housing 2 is fixedly installed at the upper middle part of the steam box 301. The first conduit 302 extends through the upper end of the housing 2 to the top of the internal conveying module 1. Three sets of nozzles 304 for spraying steam are evenly distributed from left to right at the lower end of the first conduit 302. The three sets of nozzles 304 are connected to the first conduit 302 through the connecting pipe 303. Spray holes 305 for uniformly spraying steam are evenly distributed from front to back at the lower end of the nozzles 304. A second conduit 306 for introducing residual heat from the housing 2 into the steam box 301 is fixedly installed at the upper right part of the steam box 301. The second conduit 306 is used to introduce waste heat into the steam box 301, which can improve energy utilization efficiency and make it more environmentally friendly and energy-saving. The second conduit 306 extends through the outside of the box 2 to the inside corresponding to the hot pressing component. A guide bucket 307 is fixedly installed at one end of the second conduit 306 inside the box 2. A fan 308 for drawing waste heat into the second conduit 306 is fixedly installed on the inside of the guide bucket 307. A water inlet pipe 309 for introducing water is fixedly installed on the upper left side of the steam box 301. A control valve for controlling the inlet and outlet is provided on the outside of the connection between the water inlet pipe 309 and the first conduit 302 and the steam box 301. A heating module for heating water is provided inside the steam box 301. A first control module 310 for controlling the heating temperature and working status of the heating module is fixedly installed in the middle of the end of the steam box 301 away from the box 2.

[0052] Please see Figure 5 In this embodiment, the hot pressing assembly includes a hydraulic cylinder 401, a hydraulic rod 402, a pressing block 403, and a second control module 404. Four sets of hydraulic cylinders 401 are symmetrically arranged and fixedly installed on the upper end of the housing 2. The lower end of the hydraulic cylinder 401 is fixedly connected to a hydraulic rod 402 for telescopic movement. The hydraulic rod 402 extends through the upper end of the housing 2 to the top of the internal conveying module 1. The lower ends of the four sets of hydraulic rods 402 are fixedly connected to pressing blocks 403 for hot pressing corrugated cardboard. The hydraulic cylinder 401 drives the pressing block 403 to move synchronously by controlling the up and down telescopic movement of the hydraulic rod 402. The pressing block 403 is provided with a heating coil for heating. One end of the heating coil extends through the pressing block 403 to the upper end and is fixedly connected to the second control module 404 for controlling the temperature and working state of the heating coil.

[0053] When working, first place the device in a stable position to keep it stable, and open the control valve on the outside of the water inlet pipe 309 to introduce an appropriate amount of water into the steam box, and then close the control valve on the outside of the water inlet pipe 309.

[0054] Then, the PLC controller 7 is used to turn on the switches of each component, so that each component starts to work;

[0055] Then, the heating module in the steam box is controlled by the second control module 404 to heat the steam, so that steam can be generated in the steam box and the control valve on the outside of the first conduit 302 is opened. At the same time, the heating coil in the pressure block 403 is controlled by the first control module 310 to heat the steam.

[0056] The corrugated cardboard to be shaped is then placed from the guide chute at the right end of the box 2 onto the conveying module 1, and the conveying module 1 drives the corrugated cardboard forward.

[0057] When the corrugated cardboard reaches below the nozzle 304, steam enters the nozzle 304 from the first conduit 302 and is sprayed onto the surface of the corrugated cardboard from the nozzle 305 of the nozzle 304.

[0058] Then, the corrugated cardboard continues to move forward under the action of the conveying module 1. When the corrugated cardboard reaches the bottom of the hot pressing component, the hydraulic cylinder 401 controls the hydraulic rod 402 to move downward and drive the pressing block 403 to move synchronously, so as to perform hot pressing and shaping treatment on the corrugated cardboard.

[0059] The final corrugated cardboard, after being shaped, is guided from the material guide chute at the left end of box 2 to the corresponding position;

[0060] During the shaping process of corrugated cardboard, the residual heat inside the box 2 is drawn into the second conduit 306 by the fan 308 and enters the steam box through the second conduit 306 to heat the water inside the steam box. During the shaping process, the situation inside the box 2 can be observed through the transparent glass 6 on the box door 5.

[0061] Through the above steps, by setting the box 2 so that the corrugated cardboard shaping process is carried out inside the box 2, heat loss can be reduced, making the shaping faster. By setting a waste heat recovery structure on the steam component, the waste heat can be reused. Using the waste heat to promote steam generation can improve energy efficiency, making it more environmentally friendly and energy-saving, with significant economic benefits. By setting the steam component to spray steam on the surface of the corrugated cardboard first, and then using the hot pressing component to hot press the corrugated cardboard, the quality and performance of the cardboard can be improved. This solves the problem that the existing corrugated cardboard shaping device is usually an open structure, which is prone to a lot of heat loss during the shaping process and requires a lot of energy to achieve the shaping, which easily leads to resource waste and insufficient environmental protection.
