The utility model can achieve sufficiently preheating the preheating portion without foaming by utilizing the segmented mode of horizontal preheating and vertical foaming, and the foaming portion foams efficiently along with uniformity without sticking nets and easily snapping. In addition, the heating unit and the hot-air device in a vertical heating furnace can be engaged with each other during application, thereby reducing energy consumption and reducing pollution.
Description
Technical field
The utility model relates to a kind of polyolefin coiled material foaming machine.
Background technology
Make this material of the many cavitys in inside that obtain after blowing agent decomposes, gasification is expanded after in the base material of polyolefin volume class material, evenly sneaking into blowing agent through heating, have very strong damping, heat-blocking action, be widely used in the insulation of equipment, the packing of commodity.
At present, domestic and international disclosed foaming machine mainly contains following four kinds: bath of liquid floatation type, air-cushion type, woven wire formula and vertical descending manner.Its operation principle all is by heating blowing agent to be decomposed in firing equipment, causes base material and expands, thereby reach the purpose of producing expanded material.
In disclosed these foaming machines, all exist some defective.Bath of liquid floatation type equipment in use expends great amount of water resources, and exists because the heat medium volatilization causes the ropy problem of Foam Plastic Surface of environmental pollution, production.Air-cushion type equipment then exists too big, the uneconomic problem of energy consumption.And bath of liquid floatation type, air-cushion type all are not suitable for producing slim product.The problem that woven wire formula equipment exists is: whole heater is in horizontal segment, and sheet material drags by the metal twine all the time, owing to volumetric expansion, sticking net and self adhesion phenomenon very easily takes place, thereby cause it can not be used for preparing slim product during the sheet material foaming.Though vertically descending manner equipment has overcome the adhesion problems of woven wire, can be used for producing slim product, because whole foam sheet is in vertical section, foam sheet causes longitudinal stretching easily owing to himself gravity effect, even breaks.
Summary of the invention
The utility model purpose is: a kind of polyolefin coiled material foaming machine is provided, and it adopts the horizontal preheating and the vertical segmented mode of foaming, can accomplish that the regenerator section preheating fully and not foams, the foaming of foaming section fully and evenly, sticking net, be difficult for breaking; In addition, being used of heating element heater and hot air apparatus in the vertical heating furnace reduced energy consumption, reduced pollution.
The technical solution of the utility model is: a kind of polyolefin coiled material foaming machine, comprise and unreel pay-off, heater, cooling expanding unit and traction wrap-up, described heater comprises horizontal regenerator section and vertical heating part, is provided with heating element heater and hot air apparatus in the vertical heating part;
Described horizontal regenerator section is separate horizontal preheating furnace and vertical heating furnace with vertical heating part;
Be provided with the cyclic conveyor that the furnace wall is stretched out in the rear and front end in the described horizontal preheating furnace, horizontal preheating furnace is provided with several spaced heating element heaters corresponding to the transport path of cyclic conveyor;
Described hot air apparatus is arranged at the middle part of vertical heating furnace, and heating element heater is arranged on the inwall of vertical heating furnace;
Above-mentioned heating element heater can be far infrared heating, electric heating sheets or electrically heated rod.
The utility model advantage is:
1, the utility model in use, sheet material foaming is in vertical section, is free deployed condition, sticking net phenomenon neither can occur, can realize that again foaming is fully; And regenerator section is in horizontal segment, has alleviated vertical section weight greatly, has reduced longitudinal stretching, has reduced the possibility of sheet material being broken because of the gravity effect, therefore, is suitable for producing slim product.
2, the utility model adopts the segmented mode of horizontal preheating and vertical heating, can accomplish that the regenerator section preheating fully and not foams, the heating part foaming fully and evenly, sticking net, be difficult for breaking.
3, the utility model uses heating element heater and hot air apparatus heating, and energy consumption is low, pollution-free, and wherein the setting of hot air apparatus is compared with heating element heater only is set, and can make heating more even, can reduce the quantity that is provided with of heating element heater simultaneously, thereby saves energy consumption.
4, heater of the present utility model is divided into separate horizontal preheating furnace and vertical heating furnace, has therefore avoided hot-air exchange between the two.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
