Electric-heating press machine of plastic drainage plate

Abstract

The invention relates to an electric-heating press machine of a plastic drainage plate. The electric-heating press machine includes a rack, a press roller main shaft, a press roller, two support wheel rings, electric-heating tubes and a temperature-controlling instrument. The press roller is movably connected to the rack through a bearing and the press roller main shaft. The electric-heating tubes are arranged in the press roller. The press roller main shaft is fixedly connected to the rack. The press roller is rotated around the press roller main shaft. The electric-heating tubes are uniformly distributed on the edges of the two support wheel rings through the support wheel rings fixedly arranged on the press roller main shaft in a manner of being arranged in parallel with the axial line of the press roller main shaft, wherein the parallel distance between the electric-heating tubes and an inner wall of the press roller is adjusted through bolts. The electric-heating tubes can be infrared heating tubes or electric furnace wires, of which the temperature is regulated by the temperature-controlling instrument. The electric-heating press machine is direct and simple in heating manner and is uniform and controllable in temperature. Supporting facilities of the machine occupy space hardly. The machine is high in energy utilization rate, is low in cost, and is free of pollution to environment.

Description

technical field [0001] The invention relates to a pressing machine for plastic drainage boards, in particular to a heating method and structural arrangement of pressing rollers in the pressing machine for plastic drainage boards, and belongs to the technical field of energy conversion. Background technique [0002] There are many ways to wrap the non-woven fabric on the periphery of the plastic core board to form a plastic permeable drainage board. The most primitive way is to sew the head with a sewing machine; Integral pressing type, in which the integral pressing method is widely used because of its advantages of no overlapping and less non-woven materials. The heating of the pressing roller in the existing overall pressing machine mostly adopts the heat conduction method of high-temperature oil, that is, the oil liquid is heated to an appropriate temperature and then pumped into the pressing roller, and a circulation loop is formed between the pump and the pressing rolle...

AI Technical Summary

Problems solved by technology

This method has many disadvantages; 1. It is necessary to set up a circulation system and heat preservation pipeline, and its supporting facilities are complicated, occupy a large space, and cost a lot of investment; 2. High oil consumption, oil and gas pollute the environment, and are not environmentally friendly; 3. Up and down There is a temperature difference on the pressing surface of the pressing roller, so it is difficult to guarantee the quality of hot stamping
