Abstract
The utility model discloses a kind of inflation machine heating furnace, comprise body of heater, also comprise at least two-layer heater, every layer of heater annular array is on the inner surface of body of heater, and described heater is unified to control by console.This inflation machine arranges each independent heater with heating furnace by annular array on body of heater, and after unifying to control by console, when heating film, the temperature of each heater is adjustable in real time, when film part is thicker, can suitably heighten the temperature of the heater in this region, when film part thinner, can suitably reduce the temperature of the heater in this region, make finally to obtain film thickness even, yield rate is high.
Description
Technical field
The utility model relates to heating furnace, relates in particular to a kind of inflation machine heating furnace.
Background technology
The heating furnace that inflation machine is in the market used, temperature during heating in its body of heater is single and can only unify to change, because film is in inflation process, if film temperature around rises or declines too fast, easily cause film breaks, or make film each several part thickness have big difference and cause yield rate low, therefore existing heating furnace needs stacked a plurality of hot stove when mounted, high and the inconvenient maintenance of cost, at film, enter after body of heater, again because of film each several part apart from the distance between body of heater not etc., cause the degrees of expansion of film each several part different, thereby cause the film thickness after inflation to differ, cause final yield rate low.
Summary of the invention
The defects such as the utility model is high for the cost existing in prior art, film thickness differs, yield rate is low, provide a kind of new inflation machine heating furnace.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
An inflation machine heating furnace, comprises body of heater, also comprises at least two-layer heater, and every layer of heater annular array is on the inner surface of body of heater, and described heater is unified to control by console.
By annular array on body of heater, each independent heater is set, and after unifying to control by console, when heating film, the temperature of each heater is adjustable in real time, when film part is thicker, can suitably heighten the temperature of the heater in this region, when film part thinner, can suitably reduce the temperature of the heater in this region, make finally to obtain film thickness even, yield rate is high.
As preferably, a kind of inflation machine heating furnace described above, described heater is ceramic heating plate.Ceramic heating plate structure is simple, heat up rapidly and temperature-compensating fast, its thermal efficiency is high, homogeneous heating and very energy-conservation, makes the membrane quality produced higher.
As preferably, a kind of inflation machine heating furnace described above, also comprises locating part, and described locating part is arranged at the bottom of body of heater.Locating part can prevent that film from touching the inner surface of body of heater and damaging film, improves yield rate.
As preferably, a kind of inflation machine heating furnace described above, described locating part is steady bubble frame.Simple in structure, easy for installation, and can not scratch film surface, improve yield rate.
Accompanying drawing explanation
Fig. 1 is the structural representation of heating furnace for a kind of inflation machine of the utility model;
Fig. 2 is the cross-sectional view of body of heater in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing 1-2 and the specific embodiment, the utility model is described in further detail, but they are not to restriction of the present utility model:
embodiment 1
As shown in Figure 1 and Figure 2, a kind of inflation machine heating furnace, comprises body of heater 2, also comprises at least two-layer heater 1, and every layer of heater 1 annular array is on the inner surface of body of heater 2, and described heater 1 is unified to control by console.
During work, heater 1 on body of heater 2 inner surfaces is unified heat temperature raising by console, wherein heater 1 temperature of body of heater 2 middle and upper parts and body of heater 2 middle and lower parts is relatively low, heater 1 temperature at body of heater 2 middle parts is relatively high, make the temperature in body of heater 2 be mild curve distribution, film from body of heater 2 tops enter body of heater 2 interior, will slowly be heated expansion, the moulding of slowly lowering the temperature again after expanding; In expansion process, if a film part is far away apart from body of heater 2 inner surfaces, can suitably heighten the temperature of the heater 1 of respective regions, if a film part is nearer apart from body of heater 2 inner surfaces, can suitably reduce the temperature of the heater 1 of respective regions, film various piece in expansion process is heated evenly, makes the film various piece consistency of thickness of final molding, quality is higher.
As preferably, described heater 1 is ceramic heating plate.
As preferably, also comprise locating part 3, described locating part 3 is arranged at the bottom of body of heater 2.
As preferably, described locating part 3 is steady bubble frame.
In a word, the foregoing is only preferred embodiment of the present utility model, the equalization that all scopes of applying for a patent according to the utility model are done changes and modifies, and all should belong to covering scope of the present utility model.
