[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper and one layer of cardboard. It has high mechanical strength and can withstand collisions and drops during handling. In the corrugated cardboard processing, the cardboard needs to be glued manually, and then the corrugated core paper is laid flat on top. Then, it is pressed and laminated by extrusion equipment. After lamination, it needs to be concentrated in a drying room for drying. This processing mode results in waste due to multiple handling in the middle. Moreover, the handling process can easily cause the corrugated cardboard that is not completely dried to deform, resulting in poor quality. It requires centralized inspection and may even be scrapped, causing great waste in production.

[0003] Therefore, it is necessary to improve the extrusion device for environmentally friendly corrugated cardboard to solve the above-mentioned technical problems. Utility Model Content

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this utility model can be combined with each other. The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Reference Figures 1 to 6 As shown, this utility model provides an environmentally friendly corrugated cardboard extrusion device, including an operating platform 1. The operating platform 1 is equipped with a heating component. A reciprocating motion mechanism and an extrusion mechanism are arranged sequentially from bottom to top on the operating platform 1. The reciprocating motion mechanism includes a slide rail 15 arranged parallel to the operating platform 1. A slider 16 is slidably limited and connected to the slide rail 15. Bearing seats 20 are provided at both ends of the slide rail 15. A reciprocating screw 21 is rotatably connected between the two bearing seats 20. One end of the reciprocating screw 21 is connected to the output end of a motor 22. The slider 16 is threadedly connected to the reciprocating screw 21. A crossbar 17 is connected to the side of the slider 16 away from the slide rail 15. The crossbar 17 is arranged along the width direction of the operating platform 1. A dust blowing component and a glue spraying component are provided on the crossbar 17.

[0023] In this embodiment, a guide groove 23 is provided on one side of the slide rail 15. Two fixed shafts 24 are connected to the side of the slider 16 near the slide rail 15, and the two fixed shafts 24 are arranged collinearly. A rotating wheel 25 is rotatably connected to the fixed shaft 24. The rotating wheel 25 is slidably limited in the guide groove 23, thereby realizing that the slider 16 is slidably limited on the slide rail 15.

[0024] The motor 22 drives the reciprocating screw 21 to rotate on the two bearing seats 20. The slider 16 is threadedly connected to the reciprocating screw 21 and moves back and forth along the slide rail 15 under the limiting action of the guide groove 23. This drives the dust blowing component to blow away the dust from the cardboard and corrugated core paper. After the dust blowing operation is completed, the reciprocating motion mechanism can also drive the glue spraying component to spray glue on the surface of the cardboard. The extrusion mechanism extrudes the cardboard and corrugated core paper to form corrugated paper. At the same time, the heating component dries and heats the corrugated paper to accelerate the curing of the glue and shorten the corrugated paper forming time.

[0025] Furthermore, the extrusion mechanism includes a horizontal plate 6, one end of which is vertically connected to a support plate 5, and the other end of the support plate 5 is connected to one end of the operating platform 1 in a C-shape. A hydraulic cylinder 7 is connected to the middle of the horizontal plate 6, and an extrusion plate 8 is connected to the output end of the hydraulic cylinder 7. The extrusion plate 8 is arranged parallel to the operating platform 1. Two sets of slide rods 9 are slidably arranged on the horizontal plate 6, and the two sets of slide rods 9 are symmetrically arranged on both sides of the hydraulic cylinder 7. The bottom end of the slide rod 9 is connected to the top end of the extrusion plate 8. A spring 11 is sleeved on the slide rod 9, and a gap is provided between the slide rod 9 and the spring 11. The bottom end of the spring 11 abuts against the top end of the extrusion plate 8. An adjusting nut 10 is threadedly connected to the top end of the slide rod 9, and the adjusting nut 10 is in frictional contact with the spring 11.

[0026] The extension end of the hydraulic cylinder 7 drives the extrusion plate 8 to move downward. The extrusion plate 8 drives the slide bar 9 to slowly press down along the horizontal plate 6, thereby ensuring the smoothness of the movement. In this embodiment, there are two slide bars 9 in each group. When the extrusion plate 8 is about to contact the cardboard, the adjusting nut 10 on the slide bar 9 will first contact the spring 11. As the slide bar 9 moves down continuously, the spring 11 is compressed, so that the extrusion plate 8 is subjected to uniform force, thereby ensuring the flatness of the extrusion plate 8 and the operating platform 1, and ensuring that the corrugated paper is subjected to uniform extrusion pressure.

[0027] By adjusting the position of the adjusting nut 10 on the slide bar 9, the stroke of the extrusion plate 8 is controlled, thereby controlling the distance between the extrusion plate 8 and the operating platform 1, thus realizing the pressure forming of paperboard and corrugated core paper of different thicknesses.

[0028] Furthermore, an air guide cavity 12 is provided inside the extrusion plate 8, and multiple air jet holes 13 are provided at equal intervals in an array at the bottom end of the extrusion plate 8. All the multiple air jet holes 13 are connected to the air guide cavity 12, and multiple air pipe quick connectors 14 are connected to the air guide cavity 12. All the multiple air pipe quick connectors 14 are connected to electric heaters.

[0029] The electric heater in this embodiment is described below;

[0030] An electric heater, also known as an electric fan heater, is a device that converts electrical energy into heat energy. It is primarily used to provide a warm and comfortable indoor environment during winter or cold weather. Below is some basic information about electric heaters:

[0031] Working principle: The working principle of an electric heater is relatively simple. It uses an electric heating element (such as a heating wire, PTC ceramic heating element, etc.) to generate heat, and then blows the hot air out through a fan to achieve a heating effect. The electric heating element generates heat after being powered on, and this heat is transferred to the air through heat sinks or air ducts, and then blown into the room by the fan.

[0032] Types: There are various types of electric heaters, including convection heaters, oil-filled radiators, PTC ceramic heating element heaters, halogen tube heaters, quartz tube heaters, and mini-sun heaters. Each type of electric heater has its own characteristics and applicable scenarios. For example, convection heaters achieve warmth through natural convection, providing a large and even heat dissipation area; oil-filled radiators use heat-conducting oil as the heat medium, offering excellent heat dissipation and a long service life.

[0033] Features: Electric heaters offer advantages such as rapid heating, ease of use, and high portability. They can quickly raise the room temperature, providing warmth. Furthermore, electric heaters are typically small, lightweight, and easy to carry and move, making them ideal for use in homes, offices, schools, and other similar locations.

[0034] Safety Precautions: When using an electric heater, please pay attention to safety. First, ensure the heater is placed on a stable surface to prevent it from tipping over or falling. Second, keep it away from flammable and explosive materials to avoid the risk of fire or explosion. Furthermore, constantly monitor the heater's operating status during use. If any abnormalities are detected, immediately stop using it and contact a professional for repair.

[0035] Energy Consumption and Maintenance: The energy consumption of an electric heater depends on its power and usage time. Generally, the higher the power and the longer the usage time, the higher the energy consumption. To reduce energy consumption, choose an electric heater with energy-saving features and adjust the temperature and fan speed appropriately during use. Regular cleaning and maintenance of the electric heater are also necessary, as this helps extend its lifespan and maintain stable performance.

[0036] Warm air enters and exits the air chamber 12 through the electric heater, and the warm air is blown onto the corrugated paper through the air jet 13, which accelerates the drying and shaping of the corrugated paper.

[0037] Furthermore, the heating assembly includes an electric heating tube 3, and a groove 2 is provided on the top surface of the operating platform 1. The electric heating tube 3 is arranged in a serpentine pattern in the groove 2. A heat-conducting plate 4 is fastened on the groove 2. The bottom surface of the heat-conducting plate 4 is in contact with the electric heating tube 3, and the top surface of the heat-conducting plate 4 is flush with the top surface of the operating platform 1.

[0038] In the non-example embodiment, the heat-conducting plate 4 is a copper plate, which accelerates heat exchange and allows the heat from the electric heating tube 3 to be conducted to the corrugated paper, further accelerating the drying and forming time of the corrugated paper.

[0039] Furthermore, the dust blowing assembly includes a plurality of air nozzles 18 evenly spaced along the length of the crossbar 17, and each of the plurality of air nozzles 18 is connected to an air pump via a hose.

[0040] In this embodiment, the air pump is a commercially available component and is existing technology. The air pump supplies air to each nozzle 18, and the air blows onto the cardboard or corrugated core paper to remove surface foreign matter and dust, thus preventing contamination of the adhesive and ensuring the effectiveness of the bonding and lamination.

[0041] Furthermore, the glue spraying assembly includes a plurality of glue spray nozzles 19 evenly spaced along the length of the crossbar 17, and each of the plurality of glue spray nozzles 19 is connected to a glue spraying pump via a pipeline.

[0042] In this embodiment, the glue spraying pump is a conventional component and is existing technology. The glue is sprayed onto the entire surface of the cardboard in a certain set amount through the glue spraying nozzle 19 and driven by the reciprocating motion mechanism.

[0043] The environmentally friendly corrugated cardboard extrusion device provided by this utility model works as follows: First, the electric heating element 3 is turned on for preheating. Then, the corrugated core paper is placed on the heat-conducting plate 4. The motor 22 is started, driving the reciprocating screw 21 to rotate on the two bearing seats 20. The slider 16 is threadedly connected to the reciprocating screw 21 and, under the limiting action of the guide groove 23, reciprocates along the slide rail 15. Simultaneously, the air pump is started to blow away the dust from the corrugated core paper. Then, the corrugated core paper is removed and replaced with cardboard to complete the dust removal operation on the cardboard. Next, the glue spraying pump is started to spray glue onto the cardboard. Then, the glue spraying pump is turned off, and the dust-removed corrugated core paper is placed on the cardboard that has been sprayed with glue. Next, turn on the glue spraying pump again to spray glue onto the corrugated core paper. Then, lay another piece of cardboard on top of the corrugated core paper. It should be noted that the above operation is repeated according to the number of layers of corrugated paper to be processed. After stacking the corrugated core paper and cardboard, place the slider 16 at one end of the slide rail 15 and turn off the motor 22. The purpose is to avoid the crossbar 17 interfering with the extrusion plate 8. Start the hydraulic cylinder 7. The hydraulic cylinder 7 drives the extrusion plate 8 and the slide bar 9 to move slowly downwards vertically along the crossbar 6 to extrude the stacked corrugated core paper and cardboard. At the same time, start the electric heater to blow warm air onto the corrugated paper. Meanwhile, the bottom surface of the corrugated paper is dried under the heat radiation of the heat conduction plate 4.

[0044] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
