Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboard processing, in particular to a hot plate machine used in a corrugated paperboard production line. Background Art

[0002] In the corrugated cardboard production line, a hot plate machine is used to provide heat for the bonding between papers, so that the papers are formed by drying and bonding. The papers pass through the hot plates and, through contact with the hot plates, take away the heat of the hot plates, evaporate the moisture in the adhesive, dry the paper and the adhesive, make the papers bond together, and accelerate the forming of the corrugated cardboard.

[0003] Chinese patent publication number CN216466541U, publication date 20220510, discloses a hot plate machine for a corrugated cardboard production line, including a mounting frame, a suction fan is arranged at the inner bottom end of the mounting frame near one end edge, a drying cylinder is arranged at the inner bottom end of the mounting frame at the other end of the suction fan, a box cover is arranged at one side surface of the mounting frame near the upper end edge, and an abutment roller is arranged at the inner part of the mounting frame near the top edge.

[0004] The hot plate machine used in the above-mentioned existing corrugated cardboard production line removes water vapor in the air through a drying cylinder, heats the air at the same time, and then blows it to the corrugated cardboard to ensure that the adhesive between the corrugated cardboards is accelerated to bond. In the specific implementation process, although the shaping and drying of the cardboard can be stably achieved, when adapting to the shaping and drying of cardboards of different thicknesses, it is often necessary to manually adjust the position of the abutment roller. Manual adjustment is relatively inconvenient and affects the working efficiency of the hot plate machine. Therefore, it is urgent to propose a corresponding hot plate machine for a corrugated cardboard production line to solve the above problems. Utility Model Content
