Abstract
The utility model discloses a melt tube structure for a plastic laminating machine. The melt tube structure comprises a melt tube and a filtering net arranged on the rear part of the melt tube, wherein multiple heating wires are arranged on an inner wall of the melt tube; a cylindrical electric heating tube is arranged at a central position of the melt tube; two ends of the electric heating tube stretch out of the melt tube; a thermal insulation layer is arranged on the peripheral surface of the melt tube. According to the melt tube structure, electric heating mechanisms are arranged at the central position and inner wall of the melt tube, raw materials are directly heated and melted, the consistency of raw material melting degree is improved, and the product quality is guaranteed. Meanwhile, according to the built-in electric heating mechanisms, heat loss is reduced, the heat loss is further avoided through the thermal insulation layer, the energy utilization efficiency is improved, and the cost is reduced.
Description
[technical field]
The utility model relates to plastic coating machine, especially the improvement of the melt tubular construction of plastic coating machine.
[background technology]
Multiple film plastic woven cloth has been widely used in the industries such as chemical industry, agricultural, food, cement, and it had both strengthened the tensile strength of woven cloth, had again air-tightness and moisture resistance that bag film is good, was a kind of good compound package material.
At present, widely used plastic coating machine, generally comprises ripening device used, mould mouth and roll forming device, wherein ripening device used capacity feeder, the stock melting device of comprising.After adding capacity feeder, raw material (pulvis or particle) by catch bar, raw material is pushed in stock melting device, melt pipe melts to heating raw materials, end at melt pipe is equipped with filter screen, melt filters when being pushed out stock melting device, melt after filtration is squeezed into mould mouth, then flows to and on roll forming device, carry out roll forming.
It is by the outer wall at melt pipe, heating wire being set that melt pipe melts to heating raw materials, and the heat by heating wire of melt pipe passes to raw material, melts.This mode of heating capacity usage ratio is very low, first, the heat of heating wire will first be delivered on melt pipe, and then melt pipe is passed to raw material by heat again, heat loses greatly in transmittance process, secondly, heating wire and melt pipe itself are to expose aerially, and many heats are all dispersed in workshop, and, such mode of heating causes the raw material fusing degree of raw material fusing degree Gao，Er center of periphery low, causes the product quality extruded poor.
[summary of the invention]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of melt tubular construction of plastic coating machine, can make full use of heat energy, and can improve the uniformity of raw material amount of cure, improving product quality.
For achieving the above object, the utility model proposes a kind of melt tubular construction of plastic coating machine, comprise melt pipe and the filter screen that is located at melt pipe rear portion, the inwall of described melt pipe is provided with some heating wire, melt Guan center is provided with columniform electrothermal tube, the two ends of electrothermal tube reach the outside of melt pipe, and the outer peripheral face of melt pipe is provided with insulating.
As preferably, described electrothermal tube is through melt Guan axle center.
As preferably, the thickness of described insulating is 5～15 millimeters.
The beneficial effects of the utility model: the utility model all arranges electrothermal mechanism on melt Guan center and inwall, directly raw material is carried out to heating and melting, have improved the uniformity that raw material melts degree, have guaranteed product quality.Meanwhile, electrothermal mechanism is built-in, has reduced thermal loss, and further avoids thermal loss by insulating, has improved efficiency of energy utilization, has reduced cost.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the melt tubular construction of the utility model plastic coating machine.
[specific embodiment]
Consult Fig. 1, the melt tubular construction of plastic coating machine, comprise melt pipe 1 and the filter screen 2 that is located at melt pipe 1 rear portion, the inwall of described melt pipe 1 is provided with some heating wire 5, the center of melt pipe 1 is provided with columniform electrothermal tube 3, the two ends of electrothermal tube 3 reach the outside of melt pipe 1, and the outer peripheral face of melt pipe 1 is provided with insulating 4.Described electrothermal tube 3 is through the axle center of melt pipe 1, easy for installation, and can make slaking (thawing) more even, guarantees the uniformity of overlay film product.The thickness of described insulating 4 is 5～15 millimeters, and this thickness can be guaranteed heat insulation effect, is unlikely to again too high increase cost.
The utility model arranges the electrothermal tube 3 through its central shaft in the center of melt pipe 1, run through whole melt pipe 1, improve the efficiency of heating surface, some heating wire 5 are set on the inwall of melt pipe 1, heating wire 5 is uniformly distributed along the inwall of melt pipe 1, the raw material of periphery is carried out to effective integration, and both are in conjunction with having improved the uniformity that raw material merges.Meanwhile, heating wire 5 and electrothermal tube 3 are built-in, have reduced thermal loss, and have further avoided thermal loss by insulating 4, have improved efficiency of energy utilization, have reduced cost.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
