Pearl cotton board compound machine

Abstract

The invention discloses a pearl cotton board compound machine. The pearl cotton board compound machine comprises a rack, the rack is provided with a fixed frame, adjusting frames are arranged on the two sides of the fixed frame, and the fixed frame is connected with a heating compound mechanism; the heating compound mechanism comprises two pressing rollers and a heating device, the heating deviceis composed of an air blower, heating pieces and pipelines, and the heating pieces comprise heat collecting tubes and connecting pipes; the heat collecting tubes are arranged on the rack and located under the two pressing rollers, and the connecting pipes are distributed on the lower end faces of the heat collecting tubes at equal intervals; inner cavities of the connecting pipes communicate withinner cavities of the heat collecting tubes, and a heat conducting column is placed in each connecting tube; and an electric heating wire is arranged on each heat conducting column in a penetrating mode, and the two ends of each electric heating wire stretches out of the corresponding connecting pipe and then are further connected with a power supply with the exterior voltage being 380 V. By adopting the technical scheme, the pearl cotton board compound machine is simple in structure, and can quickly compound two pearl cotton boards, the heating efficiency is greatly improved, and the energy saving effect is achieved.

Description

technical field [0001] The invention relates to the field of pearl cotton board production machinery, in particular to a pearl cotton board composite machine. Background technique [0002] Pearl cotton, also known as EPE pearl cotton polyethylene foamed cotton, has a non-crosslinked closed-cell structure and is a new type of environmentally friendly packaging material. It is composed of low-density polyethylene fat through physical foaming to produce countless independent bubbles. It overcomes the shortcomings of ordinary styrofoam that are fragile, deformed, and poor in recovery. It has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc., and also has good chemical resistance. It is an ideal substitute for traditional packaging materials. Widely used in car cushions, pillows, electronic appliances, instruments, c...

Problems solved by technology

[0004] The pearl cotton board composite machines on the market now use a hot air blower to blow air at more than 300 degrees between the two pearl cotton boards, so that the surface of the two pearl cotton boards melts, and the composite can be realized after they are attached to each other, but The heating equipment of this structure has a rectangular heating box, and the hot air blower needs a long time to preheat the heating box, and the distance between the hot air blower and the heating box is relatively long, resulting in low heat utilization rate and can not achieve energy saving. effect while greatly reducing production efficiency
