Abstract
Description
Technical Field
[0001] This utility model relates to the field of corrugated cardboard rolling technology, and more specifically to a pressure roller assembly for corrugated cardboard resistant to damp heat aging. Background Technology
[0002] Corrugated cardboard is an environmentally friendly material made of corrugated core paper layers bonded together with multiple layers of cardboard. Its unique structure gives it excellent compressive strength and cushioning properties. As a commonly used material in the packaging industry, it is widely used for the transportation and protection of goods such as food, electronic products, and furniture, and is lightweight and durable. In addition, corrugated cardboard has innovative applications in industry, construction, and art, such as in the manufacture of shipping boxes, architectural partitions, and installation art. Its high recyclability and printability make it a model of green packaging. During the production and processing of corrugated cardboard, pressure roller assemblies are often used to roll and press the cardboard to improve its flatness.
[0003] The existing pressure roller assembly cannot adjust the height. The fixed-height pressure roller cannot match different specifications of paperboard. Thinner paperboard may not be properly pressed due to excessive gaps, resulting in loose surface fibers and low flatness. Thicker paperboard may be over-compressed due to insufficient gaps, resulting in significant deformation in the middle and indentations or wrinkles on both sides. In addition, uneven heating of the hot pressure roller can easily cause inconsistent thermal expansion, which can damage the parallelism of the roller gaps and lead to uneven transverse thickness and poor board shape of the paperboard.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The pressure roller assembly for resistant to damp heat aging corrugated cardboard involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Reference Figure 1-4 This utility model provides a pressure roller assembly for corrugated cardboard that is resistant to humid heat aging. It includes a main body 1, a hot pressure roller mechanism 2 fixedly connected to the main body 1, a lifting mechanism 3 inside, and four fixed plates 4 fixedly connected to the inner side of the bottom end. The lifting mechanism 3 is below the hot pressure roller mechanism 2. The surface of the components is coated with PTFE to prevent the components from aging due to humid heat environment.
[0021] The main body of the component 1 includes a component shell 101, a fixing frame 102, support legs 103, and a balance pad 104. Four support legs 103 are fixedly connected to the four corners of the bottom of the component shell 101. The balance pad 104 is fixedly connected to the end of the support leg 103 away from the component shell 101. The balance pad 104 distributes the weight of the equipment evenly to the ground by increasing the support area, preventing the equipment from tilting or overturning due to an unstable center of gravity. The fixing frame 102 is fixedly connected to the top of the component shell 101 to enhance structural stability. Two symmetrical fixing plates 4 are fixedly connected to the inner wall of the bottom of the component shell 101.
[0022] The hot press roller mechanism 2 includes a connecting frame 201, a roller 202, a rotating rod 203, a hot air box 204, a connecting sleeve rod 205, a hot air blower 206, and a first motor 207. The connecting frame 201 is fixedly connected to the inner walls of both sides of the component housing 101. The roller 202 is installed inside the connecting frame 201. Rotating rods 203 are fixedly connected to both ends of the roller 202. The rotating rods 203 pass through the connecting frame 201 and are rotatably connected to it. The side of the rotating rod 203 away from the connecting frame 201 is rotatably connected to the inner wall of the component housing 101. One of the rotating rods 203 passes through the component housing 101, and the end away from the connecting frame 201 is fixedly connected to the first motor 207. The hot air box 204 is fixedly connected to the top of the connecting frame 201. There is an opening between the hot air box 204 and the connecting frame 201. The hot air box 204 is connected to the fixing frame 102 on both sides. The hot air box 204 is fixedly connected to a connecting sleeve 205, which is threadedly connected to a hot air blower 206. A sealing gasket is provided at the connection between the connecting sleeve 205 and the hot air blower 206 to improve sealing. The threaded connection facilitates disassembly of the hot air blower 206 in case of damage, reducing maintenance costs. When the hot air blower 206 is started, hot air is evenly heated to the roller 202 through the hot air box 204 and the connecting frame 201. This uniform heating design avoids performance degradation caused by localized overheating, ensuring the pressure roller continuously provides stable pressure in a humid environment, thereby improving the forming accuracy and structural strength of the corrugated cardboard. Simultaneously, the first motor 207 is started, driving the rotating rod 203, which is fixedly connected to the output end of the first motor 207, to rotate. The rotation of the rotating rod 203 drives the roller 202 to rotate, pressing the corrugated cardboard.
[0023] The lifting mechanism 3 includes four limiting plates 301, a scale shaft 302, a conveyor table 303, a fixing block 304, a second motor 305, a drive rod 306, a first connecting rod 307, and a second connecting rod 308. The limiting plates 301 are four in number and are fixedly connected to the scale shaft 302. The scale shaft 302 is fixedly connected to the four corners of the bottom inner wall of the component housing 101. The scale shaft 302 is movably connected to the conveyor table 303. The bottom of the conveyor table 303 has two fixing blocks 304 corresponding to the fixing plate 4. The fixing plate 4 is rotatably connected to the drive rod 306. One end of the drive rod 306 passes through the component housing 101 and is fixedly connected to the second motor 305. The connection point between the drive rod 306 and the second motor 305 is the output end of the second motor 305. The first connecting rod 307 is fixedly connected to the drive rod 306 and to the fixing plate 4. The first connecting rod 307, with its end away from the fixed plate 4, is rotatably connected to the fixed block 304. First, the corrugated cardboard is conveyed to a position via the conveyor table 303. Then, the second motor 305 starts, driving the drive rod 306 to rotate, which in turn causes the first connecting rod 307, which is fixedly connected to the drive rod 306, to swing up and down. This causes the second connecting rod 308, which is movably connected to the first connecting rod 307, to swing up and down. The second connecting rod 308 is rotatably connected to the fixed block 304, which is fixed to the conveyor table 303. This allows the conveyor table 303 to rise and fall vertically, matching different cardboard sizes. After adjusting the height to a suitable position, the first motor 207 is started for roller pressing. The operator records the possible rising and falling positions and can directly start the first motor 207 for roller pressing later.
[0024] The working principle of this utility model:
[0025] First: The corrugated cardboard is first transported to its position using conveyor 303.
[0026] Secondly: The starting of the second motor 305 drives the active rod 306 to rotate, thereby causing the first connecting rod 307, which is fixedly connected to the active rod 306, to swing up and down. This causes the second connecting rod 308, which is movably connected to the first connecting rod 307, to swing up and down. The second connecting rod 308 is rotatably connected to the fixed block 304, which is fixed on the conveyor table 303. This allows the conveyor table 303 to be raised and lowered vertically, adjusting the height to a suitable position. The operator records the height adjustment position.
[0027] Finally: Start the hot air blower 206. Hot air will evenly heat the roller 202 through the hot air box 204 and the connecting frame 201. Through the uniform heating design, performance degradation caused by local overheating can be avoided, ensuring that the pressure roller continuously provides stable pressure in a humid and hot environment, thereby improving the forming accuracy and structural strength of the corrugated cardboard. At the same time, start the first motor 207, which drives the rotating rod 203 fixedly connected to the output end of the first motor 207 to rotate. The rotation of the rotating rod 203 drives the roller 202 to rotate, and roll the corrugated cardboard.
[0028] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
