Embodiment Construction
[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0016] The present invention is a single-sided corrugated cardboard production line capable of double-sided preheating. The structure is as follows: figure 1 As shown, it includes plane cardboard preheating device A, corrugating roll A1, corrugating roll B2, smooth roll 3 and plane cardboard preheating device B arranged in sequence. An oven A4 is arranged above the plane cardboard preheating device A, and the air of the oven A4 The nozzle is set facing the plane cardboard preheating device A, the air inlet and return air outlet of the oven A4 are connected to the gas heat exchanger A5 through pipelines, and the heating package I16 is installed on the connecting pipeline between the air inlet of the oven A4 and the gas heat exchanger A5 The roll face side of the corrugating roll A1 is provided with a high-frequency heating device A6, and the h...

The invention discloses a single-sided corrugated board production line capable of preheating on both sides. The single-sided corrugated board production line comprises a planar paperboard preheating device A, a corrugated roller A, a corrugated roller B, a smooth roller and a planer paperboard preheating device B which are sequentially arranged, wherein a drying oven A is arranged above the planar paperboard preheating device A; the drying oven A is connected with a gas exchanger A; one side of the roller surface of the corrugated roller A is equipped with a high-frequency heating device A; the high-frequency heating device A is opposite to the roller surface of the corrugated roller A; one side of the roller surface of the corrugated roller B is equipped with a high-frequency heating device B; the high-frequency heating device B is opposite to the roller surface of the corrugated roller B; a gluing device is arranged at the other side of the roller surface of the corrugated roller B; a high-frequency heating device C is arranged at one side of the smooth roller; the high-frequency heating device C is opposite to the roller surface of the smooth roller; a drying oven B is arranged above the planar paperboard preheating device B; and the drying oven B is connected with a gas heat exchanger B. The single-sided corrugated board production line solves the problem that an existing single-sided corrugated board production way has energy waste and pollutes the environment.
Description
technical field [0001] The invention belongs to the technical field of corrugated cardboard production equipment, and in particular relates to a single-sided corrugated cardboard production line capable of double-sided preheating. Background technique [0002] Single-sided corrugated cardboard is to press the flat cardboard to form corrugated paper first, and then glue the folded paper and the flat cardboard together to form a single-sided corrugated cardboard. The flat cardboard must be preheated first. The existing preheating method is to place the flat cardboard on a large cylinder, pass steam into the cylinder, and heat the wall of the cylinder through the steam, so that the There are two problems in this preheating method: one is the waste of heat, and the whole cylinder must be heated, but the plane cardboard only occupies a part of the large cylinder, thus causing energy waste; the other is the current preheating The steam in the method needs to burn coal to heat the...
