Abstract
The utility model relates to a heater for a multilayer sheet coextruder, which comprises a plurality of heating rings arranged outside an extrusion cylinder. The heater is characterized by also comprising a heat source box, an air inlet pipe, an air outlet pipe and a plurality of heating air rings, wherein the heat source box is provided with an air supply port and an air return port; the heating air rings and the heating rings are alternately arranged outside the extrusion cylinder; each heating air ring is provided with an air inlet and an air outlet; the air supply port is connected with the air inlet through an air inlet pipe; and the air return port is connected with the air outlet through the air outlet pipe. The heating ring and the heating air ring are alternately arranged on the extrusion cylinder to perform heating, and the heating air rings adopt the hot air hating mode, so that the extrusion cylinder is heated more uniformly; and thus, the plastics in the extrusion cylinder are heated more uniformly, thereby enhancing the quality of the formed sheet. The heated air still has higher temperature, and thus, is sent back to the heat source box to perform heating, so the hot air is recycled, thereby greatly reducing the energy loss; and thus, the heater is more energy-saving and environment-friendly, lowers the production cost, and has obvious economic benefit.
Description
Technical field
The utility model relates to a kind of heater, relates in particular to the heater of multi-layer co-extruded sheet material machine.
Background technology
Multi-layer co-extruded sheet material machine generally comprises frame, and is successively set on extruder, extrusion die, tablet press machine, cooling bead cutter, haulage gear and wrap-up in frame, the packing cylinder that extruder comprises many extrusion screw rods and is enclosed within extrusion screw rod outside.In order to control the temperature of plastics in packing cylinder, generally in the outside of packing cylinder, heating collar is set packing cylinder is heated, heating collar is even not to the heating of packing cylinder, causes the plastics temperature in packing cylinder even not, has affected the quality of formed sheet; In addition, the heat energy loss of heating collar is serious, causes energy waste, has indirectly increased production cost.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of heater of multi-layer co-extruded sheet material machine, and the heater of this multi-layer co-extruded sheet material machine can improve the quality of formed sheet, and energy-conserving and environment-protective more.The technical scheme adopting is as follows:
The heater of multi-layer co-extruded sheet material machine, comprises a plurality of heating collars that are arranged on packing cylinder outside, it is characterized in that: also comprise heat source case, air inlet pipe, escape pipe and a plurality of hot air ring that adds; Heat source case is provided with air outlet and return air inlet; Add the alternate outside that is arranged on described packing cylinder of hot air ring and heating collar; Add hot air ring and be provided with air inlet and air outlet; Air outlet is connected with air inlet by air inlet pipe, and return air inlet is connected with air outlet by escape pipe.
Heat source case is sent hot gas by air outlet, through air inlet pipe, is sent to and adds in hot air ring, and packing cylinder is heated, and the gas after heating is sent back in heat source case and reheated through air outlet, escape pipe, return air inlet.Due to alternate employing heating collar on packing cylinder with add hot air ring and heat, be that the thermal recovery segmentation that adds of packing cylinder is controlled, wherein add the mode that hot air ring adopts hot gas heating, make being heated of packing cylinder more even, plastics in packing cylinder are heated more even, have improved the quality of formed sheet; Due to the gas higher temperature of tool still after heating, again to send back in heat source case and heat, hot gas cycle utilization, significantly reduces energy loss, and therefore energy-conserving and environment-protective more can be energy-conservation 30～40%, reduced production cost, and economic benefit is obvious.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment of the present utility model, be described further.
As shown in Figure 1, the heater of this multi-layer co-extruded sheet material machine, comprises a plurality of heating collars 1, heat source case 2, air inlet pipe 3, escape pipe 4 and a plurality of hot air ring 5 that adds; Heat source case 2 is provided with air outlet 6 and return air inlet 7; Add hot air ring 5 outside that be arranged on packing cylinder 8 alternate with heating collar 1; Add hot air ring 5 and be provided with air inlet 9 and air outlet 10; Air outlet 6 is connected with air inlet 9 by air inlet pipe 3, and return air inlet 7 is connected with air outlet 10 by escape pipe 4.
Heat source case 2 is sent hot gas by air outlet 6, through air inlet pipe 3, air inlet 9, is sent to and adds in hot air ring 5, and packing cylinder 8 is heated, and the gas after heating is sent back in heat source case 2 and reheated through air outlet 10, escape pipe 4, return air inlet 7.Due to alternate employing heating collar on packing cylinder 81 with add hot air ring 5 and heat, be that the thermal recovery segmentation that adds of packing cylinder 8 is controlled, wherein add the mode that hot air ring 5 adopts hot gas heating, make being heated of packing cylinder 8 more even, plastics in packing cylinder 8 are heated more even, have improved the quality of formed sheet; Due to the gas higher temperature of tool still after heating, again to send back in heat source case 2 and heat, hot gas cycle utilization, significantly reduces energy loss, and therefore energy-conserving and environment-protective more can be energy-conservation 30～40%, reduced production cost, and economic benefit is obvious.
In addition; it should be noted that, the specific embodiment described in this description, its each several part titles etc. can be different; all equivalence or simple change of doing according to described structure, feature and the principle of the utility model patent design, are included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
