Description

Technical Field

[0001] This utility model relates to the field of double E-flute corrugated cardboard production technology, and in particular to a hot plate machine for producing double E-flute corrugated cardboard. Background Technology

[0002] Double E-flute corrugated cardboard is a five-layer corrugated cardboard made by bonding two layers of E-flute corrugated paper with a linerboard and a backing liner. Double E-flute corrugated cardboard has good bidirectional stiffness, which can reduce the impact of external forces and reduce surface warping. It is commonly used for packaging electronic products, cosmetics, food, etc. During the production process of double E-flute corrugated cardboard, a hot plate machine is often used to heat it.

[0003] Chinese patent application publication number CN219312188U discloses a uniform hot plate machine for corrugated cardboard production, including a worktable. The upper surface of the worktable has a through hole. A first housing is fixedly connected to the lower surface of the worktable. A first motor is fixedly connected inside the first housing. A first rotating shaft is fixedly connected to the output end of the first motor. A first fan blade is fixedly connected to the outer wall of the first rotating shaft. A first electric heating wire is provided on the upper surface of the first fan blade. A first support is fixedly connected to the upper surface of the worktable. A top plate is fixedly connected to the upper surface of the first support.

[0004] While the aforementioned hot plate heat exchanger can simultaneously heat both sides of double-E corrugated cardboard, its multiple fan blades, each driven by an independent motor, increase the number of motors and consequently raise the energy consumption during operation. Furthermore, the motors and hydraulic cylinders are housed within the casing; as the heat exchanger operates, the internal temperature rises continuously, posing a serious threat to the normal operation of the motors and hydraulic cylinders and potentially reducing their lifespan.

The components include a first bevel gear 14 fixedly mounted on the surface of the rotating shaft 13, a second bevel gear 15 meshing with the surface of the first bevel gear 14, a first rotating rod 16 fixedly mounted inside the second bevel gear 15, the first rotating rod 16 being rotatably connected to the lower cover 2, a third bevel gear 17 fixedly mounted on the surface of the first rotating rod 16, a fourth bevel gear 18 meshing with the surface of the third bevel gear 17, and the fourth bevel gear 18 being fixedly connected to the first fan blade assembly 19, facilitating transmission when the rotating shaft 13 rotates, thereby facilitating the rotation of the first fan blade assembly 19. A rectangular rod 21 is fixedly mounted on the surface of the rotating shaft 13, a rotating column 22 is slidably connected to the surface of the rectangular rod 21, and a fixing plate 23 is rotatably connected to the surface of the rotating column 22, the fixing plate 23 being fixedly connected to the upper cover 9. A second transmission assembly is provided on the surface of the rotating column 22, and a second fan blade assembly 29 is provided on the surface of the rotating column 22 through the second transmission assembly. The second transmission assembly includes a fifth bevel gear 24 fixedly installed on the surface of the rotating column 22, a sixth bevel gear 25 meshing on the surface of the fifth bevel gear 24, a second rotating rod 26 fixedly installed inside the sixth bevel gear 25, the second rotating rod 26 being rotatably connected to the upper cover 9, a seventh bevel gear 27 fixedly installed on the surface of the second rotating rod 26, an eighth bevel gear 28 meshing on the surface of the seventh bevel gear 27, and the eighth bevel gear 28 being fixedly connected to the second fan blade assembly 29, facilitating transmission when the rotating column 22 rotates, thereby facilitating the rotation of the second fan blade assembly 29. A support is fixedly installed at the bottom of the workbench 1. The hot plate machine for producing double-E-flute corrugated cardboard has multiple support legs. It places the double-E-flute corrugated cardboard on a placement plate 3 and secures it with a fixing assembly. Then, a hydraulic push rod 8 moves the upper cover 9 downwards to fit against the lower cover 2. A drive motor 12 rotates the rotating shaft 13, which in turn drives the first transmission assembly, causing the first fan blade assembly 19 to rotate. This blows the heat generated by the first heating rod 10 towards the bottom of the double-E-flute corrugated cardboard, heating its bottom. Simultaneously, the rotation of the rotating shaft 13 drives the rectangular rod 21 to rotate, causing the rotating column 22 to rotate. This, in turn, drives the second transmission assembly, causing the second fan blade assembly 29 to rotate, blowing the heat generated by the second heating rod 11 towards the top of the double-E-flute corrugated cardboard.The top of the double-E-flute corrugated cardboard is heated by a single drive motor 12 that simultaneously drives multiple first blade groups 19 and multiple second blade groups 29. This reduces the number of motors used, significantly lowering the equipment's energy consumption. Furthermore, the drive motor 12, hydraulic push rod 8, and electric push rod 5 are all located outside the enclosure, extending their service life.

[0022] It is worth mentioning that the rectangular rod 21 is slidably connected to the rotating column 22, the rotating column 22 is rotated with the fixed plate 23, the fixed plate 23 is fixedly connected to the upper cover 9, and the fifth bevel gear 24 is fixedly connected to the rotating column 22. This ensures that the rectangular rod 21 does not affect the up-and-down movement of the upper cover 9, and that when the upper cover 9 moves up and down, the fixed plate 23, the rotating column 22, the fifth bevel gear 24, and other components also move up and down together. Furthermore, the rectangular rod 21 has a rectangular structure, and when the rectangular rod 21 rotates, it can cause the rotating column 22 to rotate, thereby causing the fifth bevel gear 24 to rotate.

[0023] Specifically, the fixing components include a support plate 4 fixedly installed at the bottom of the lower cover 2, an electric push rod 5 fixedly installed inside the support plate 4, and a pressure plate 6 fixedly installed at the output end of the electric push rod 5. The pressure plate 6 is slidably connected to the lower cover 2. The fixing components facilitate the pressing and fixing of the double E-flute corrugated cardboard, thereby facilitating more stable heating of the device in the future.

[0024] Specifically, a first mounting plate 20 is rotatably connected to the surface of the first blade assembly 19, and the first mounting plate 20 is fixedly connected to the lower cover 2. The first mounting plate 20 facilitates the more stable rotation of the first blade assembly 19. A second mounting plate 30 is rotatably connected to the surface of the second blade assembly 29, and the second mounting plate 30 is fixedly connected to the upper cover 9. The second mounting plate 30 facilitates the more stable rotation of the second blade assembly 29.

[0025] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0026] In use: Place the double E-flute corrugated cardboard on the placement plate 3. The electric push rod 5 moves the pressure plate 6 downwards, pressing the double E-flute corrugated cardboard firmly. Then, the hydraulic push rod 8 moves the upper cover 9 downwards, causing it to fit against the lower cover 2. Heating is then achieved through the first heating rod 10 and the second heating rod 11. Simultaneously, the drive motor 12 rotates the rotating shaft 13, causing the first bevel gear 14 to rotate, the second bevel gear 15 to rotate, the first rotating rod 16 to rotate, the third bevel gear 17 to rotate, and the fourth bevel gear 18 to rotate. The first fan blade assembly 19 rotates, blowing the heat generated by the first heating rod 10 toward the bottom of the double E-flute corrugated cardboard, thus heating the bottom of the double E-flute corrugated cardboard. At the same time, the rotating shaft 13 rotates, which drives the rectangular rod 21 to rotate, causing the rotating column 22 to rotate, causing the fifth bevel gear 24 to rotate, causing the sixth bevel gear 25 to rotate, causing the second rotating rod 26 to rotate, causing the seventh bevel gear 27 to rotate, causing the eighth bevel gear 28 to rotate, causing the second fan blade assembly 29 to rotate, blowing the heat generated by the second heating rod 11 toward the top of the double E-flute corrugated cardboard, thus heating the top of the double E-flute corrugated cardboard.
