[0002] Fiberboard is mainly made of wood cellulose fibers interwoven and made using their inherent adhesive properties. During the manufacturing process of fiberboard, adhesives can be applied and hot rolling can be used to strengthen the connection between wood cellulose fibers to improve the overall strength and bonding strength of the fiberboard.
[0003] During the hot rolling operation of the fiberboard, downward pressure is applied by the roller conveyor below and the high-temperature electromagnetic heating roller above, so that the fiberboard passes between the upper and lower rollers, and the fiberboard is pressed and formed after rolling by relying on the high temperature and downward pressure between the rollers. However, the inventors found that during the current hot rolling, the fiberboard is basically rolled by a single high-temperature electromagnetic heating roller, and the rolling pressure is applied to the fiberboard once, so that the fiberboard may crack and deform excessively when it is exposed to high temperature and high pressure at a single time; and at present, the preheating of the fiberboard is usually carried out by electric heating wires, which not only increases more production and processing energy, but also fails to make good use of the heat of the high-temperature electromagnetic heating roller.

[0026] Refer to the instruction manual Figure 1 To Attachment Figure 4 As shown;
[0027] The optimal technical solution for fiberboard hot roller pressing device:
[0028] This embodiment includes: a fiberboard conveying roller machine 1, and a preheating roller pressing device 2 mounted on the right side of the top surface of the fiberboard conveying roller machine 1; wherein the preheating roller pressing device 2 includes a hot air circulation preheating mechanism 21 and a plurality of groups of multi-stage roller pressing mechanisms 22 arranged on the left side of the hot air circulation preheating mechanism 21.
[0029] The hot air circulation preheating mechanism 21 includes a U-shaped frame 211 fixed on the top surface of the fiberboard conveying roller machine 1, a C-shaped air duct 214 fixed at the rear section of the front and rear side walls of the U-shaped frame 211, and a servo fan unit 213 fixed at the left port position of the U-shaped frame 211; the multi-stage rolling mechanism 22 includes a beam 221 fixed on the top surface of the U-shaped frame 211, a servo electric cylinder 224 fixed at the front and rear ends of the lower surface of the beam 221, and a high-temperature electromagnetic heating roller 223 rotatably connected to the end of the telescopic rod of the servo electric cylinder 224, and the high-temperature electromagnetic heating roller 223 is located in the inner cavity of the U-shaped frame 211.
[0030] A support plate 222 is fixed at the central position of the lower surface of the crossbeam 221, and the top surface of the support plate 222 is fixedly connected to the bottom surface of the U-shaped frame 211. A bearing 225 is fixed at the end of the telescopic rod of the servo electric cylinder 224, and the bearing 225 is sleeved on the shaft of the high-temperature electromagnetic heating roller 223 located at the front and rear positions outside the U-shaped frame 211. The preheating roller pressing equipment 2 is linearly arranged at equal distances from each other, and the high-temperature electromagnetic heating rollers 223 in the preheating roller pressing equipment 2 increase in height from left to right, and the height difference between the high-temperature electromagnetic heating rollers 223 is 1cm-2cm. Four rectangular through grooves 212 are provided at the left section of the front and rear side walls of the U-shaped frame 211 for the front and rear shafts of the high-temperature electromagnetic heating rollers 223 to pass through and rotate.
[0031] The right sections of the front and rear side walls of the U-shaped frame 211 are provided with air holes 215 for the C-shaped air duct 214 to pass through, and one end of the C-shaped air duct 214 is fixed inside the air hole 215, and the other end of the C-shaped air duct 214 passes through the right side port of the U-shaped frame 211 into the inner cavity of the U-shaped frame 211; the servo fan unit 213 includes a square frame fixed to the left port of the U-shaped frame 211, and a number of groups of servo fans are arranged and fixed at equal distances inside the square frame, wherein the servo fan unit 213 blows air to the high-temperature electromagnetic heating roller 223 to carry heat to the right side of the inner cavity of the U-shaped frame 211.
[0032] According to the above-mentioned preferred technical solution, the workflow of the technical solution is described as follows:
[0033] The fiberboard to be hot-rolled is straightened and sent into the interior of the preheating rolling equipment 2 from the right side feed port of the fiberboard conveying roller machine 1. Before the overall equipment is operated, it is necessary to start the machine to allow the high-temperature electromagnetic heating roller 223 to heat up to a high temperature state. At this time, the transportation speed of the fiberboard conveying roller machine 1 is adjusted to a slow state, and after the high-temperature electromagnetic heating roller 223 is heated up, the servo fan unit 213 slowly blows air from the left side of the U-shaped frame 211 to carry the heat of the high-temperature electromagnetic heating roller 223 to the right side of the inner cavity of the U-shaped frame 211, and the fiberboard located on the right side of the inner cavity of the U-shaped frame 211 will be baked by hot air, and the C-shaped air duct 214 collects the hot air inside the U-shaped frame 211 and re-discharges it to the fiberboard from the right end of the U-shaped frame 211, thereby realizing hot air convection inside the U-shaped frame 211.
[0034] After the servo electric cylinder 224 is controlled by the industrial computer to extend and retract its length in turn, the high-temperature electromagnetic heating rollers 223 have a height difference of 1cm-2cm with each other, so that the downward strength of the rolling increases gradually during the transportation of the fiberboard from the right side to the left side, thereby gradually rolling the fiberboard to avoid deformation or cracking due to excessive single rolling strength.
[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
