Abstract

The utility model discloses a heat-insulating plate hot-pressing device which comprises a frame, wherein a hot-pressing net is arranged on the frame and is supported by a tensioning roller, a heating roller, a pressing roller, a driving roller and a separating roller on a bracket, the hot-pressing net is a net-shaped structure woven by metal wires, and needles are arranged on the surface of the hot-pressing net. The hot-pressing net is pressed on the laminated fiber fabric layers after being heated by the heating roller, the hot-pressing net is flattened and hot-stamped with grid patterns under the heating action, the grid patterns are harder than peripheral fiber fabrics, so that the hot-pressing net has a linear shaping and supporting function, and meanwhile, needles on the surface of the hot-pressing net penetrate the center of a material when passing through the pressing roller, so that the center of the material uniformly forms dense hot-pressing points, and the compactness of the internal structure of the board is ensured.

Description

Heat insulating board hot pressing device Technical Field The utility model relates to a hot pressing device, in particular to a hot pressing device for a heat insulation plate. Background The heat insulation board commonly used in the fields of automotive interiors and the like is a board formed by stacking and hot-pressing fabrics spun by various polymer material fibers, and in the hot-pressing process of the fabrics, a pressing roller with a certain temperature is pressed on the stacked fabrics, so that the fibers shrink and are tightened under the action of pressure. Because the hot pressing process time is shorter, when the panel has certain thickness, the surface fabric that is located in the center can't be heated because the panel thickness is too thick, and the panel center is fluffy than the outside, leads to the intensity of panel to be insufficient, and the time of extension hot pressing probably leads to the panel outside to heat excessively and warp crookedly, leads to the panel to scrap. Disclosure of utility model In order to overcome the defects, the utility model provides the heat-insulating plate hot-pressing device which can uniformly heat the inside and the outside of the plate. The heat-insulating plate hot-pressing device comprises a frame, wherein a tensioning roller, a heating roller, a pressing roller, a driving roller and a separating roller are arranged on the frame, an annular hot-pressing net is sleeved on each roller in a penetrating mode, the tensioning roller is used for sleeving the hot-pressing net, needles are arranged on the surface of the hot-pressing net, and the hot-pressing net is of a net-shaped structure woven by metal wires. The two sides of the frame are symmetrically provided with oil cylinders, and piston rods of the oil cylinders are connected with two ends of the tensioning roller through gear sets. The tensioning roller is located above the separating roller, the heating roller is located above the pressing roller, the heating roller and the tensioning roller are located at the same height, and the driving roller is located at the centers of the tensioning roller, the heating roller, the pressing roller and the separating roller. The needles are arranged on the surface of the hot-pressing net, the length of each needle is 0.5-3 cm, and the distance between every two adjacent needles is 5-20 cm. The hot-pressing net has the advantages that the structural design is reasonable and ingenious, the hot-pressing net is pressed on the laminated fiber fabric layers after being heated by the heating roller, the hot-pressing net is flattened and is thermoprinted with grid patterns under the heating effect, the grid patterns are harder than peripheral fiber fabrics, so that the hot-pressing net has a linear shaping supporting effect, meanwhile, needles on the surface of the hot-pressing net penetrate the center of a material when passing through the pressing roller, so that the center of the material uniformly forms dense hot-pressing points, and the compactness of the internal structure of the plate is guaranteed.
