Abstract
The utility model relates to a difference in temperature compensation foaming furnace, including the box, the bubble in the box produces the district, follows horizontal width direction and evenly sets up a plurality of radiator unit of group, and every radiator unit of group comprises 2~3 aluminium tuberculated pipes, correspond a plurality of radiator unit of group set up a plurality of mutually independent again and mend the temperature device, mend the temperature device and heat the operation according to predetermined heating temperature. The utility model discloses a foaming furnace can provide difference in temperature compensation in the colloid foaming process, ensure that the heating temperature of the same level of colloid department is the same and sufficient, and messenger's colloid expansion rate everywhere keeps the unanimity, reduces thickness difference, improves the qualification rate of product.
Description
Technical field
This utility model belongs to the foaming furnace of macromolecular material foaming, is specifically related to a kind of vertical-foaming stove.
Background technology
PVC foam leather production process can use foaming furnace foaming PVC colloid, foaming furnace is to use high-temperature catalytic ADC blowing agents to produce gas, gas is utilized to make the PVC glue material a large amount of stingy abscesses of internal generation of molten condition, prolongation over time, crafters gradually increases increase makes PVC colloidal volume expand several times even tens times, uses cooling embossed technology to form various PVC foam leather subsequently.
In commercial production, the general foaming furnace used can be divided into vertical (console model) and box (ground-above type), and each producer selects to use according to actual needs.From the point of view of vertical-foaming stove, due to its internal special design, the radiator that furnace heat is corresponding is all disposed within more than body of heater centrage, by thermal cycle pipeline by heat blow to PVC leather top and bottom.Temperature Distribution in existing vertical-foaming furnace box body is the feature that center is high, case both sides are low, causes leather cannot obtain uniform heating-up temperature.And ADC activation and gas forming amount are influenced by temperature very big, the fast gas forming amount of temperature overactivity is big, otherwise then the least.There is difference in the expansion rate thus making PVC leather same level line, causes the uneven thickness of leather.
It addition, in PVC semifinished leather products manufacturing process, affected by equipment and operator's mode of operation, PVC foam can produce difference in the same horizontal line, makes end article not meet production standard in uniform thickness.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of foaming furnace for above-mentioned prior art, arrange by improving heating, guarantee the uniform and steady of wind pushing temperature, cause the difference of colloid expansion rate because of the temperature difference during solution PVC foam, improve the qualification rate of foaming product.
The technical scheme in the invention for solving the above technical problem is: a kind of temperature difference compensation foaming furnace, including casing, gas bubble generating area in casing, is uniformly arranged some groups of radiating subassemblies along horizontal width direction, and often group radiating subassembly is made up of 2～3 aluminum fin-stock radiating tubes；Corresponding described some groups of radiating subassemblies arrange some separate benefit temperature devices again, and described benefit temperature device carries out heating operation according to the heating-up temperature preset.
Preferably, described radiating subassembly is at least three groups, is separately positioned on the position, left, center, right of casing width.
Relatively reasonably arranging and be, the default heating-up temperature of some described benefit temperature devices is identical.
Compared with prior art, the utility model has the advantage of: provide the foaming furnace of a kind of improvement, temperature difference compensation can be provided in colloid foaming process, guarantee that the heating-up temperature at colloid same level is identical and sufficient, colloid expansion rate everywhere is made to keep consistent, reduce difference in thickness, improve the qualification rate of product.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of temperature difference compensation foaming furnace in this utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As shown in Figure 1, temperature difference compensation foaming furnace in the present embodiment, including casing 1, the right and left of casing 1 is provided with needle plate 2, gas bubble generating area in casing 1 i.e. high-temperature heating district, be uniformly arranged three groups of radiating subassemblies along horizontal width direction, radiating subassembly is arranged at the left, center, right three of casing, and often group radiating subassembly is made up of 2 aluminum fin-stock radiating tubes 3；Corresponding three groups of radiating subassemblies arrange three groups of separate benefits temperature device (being not drawn in figure) again, and benefit temperature device carries out heating operation according to the heating-up temperature preset and three groups of default heating-up temperatures mending temperature devices are identical.
The foaming furnace of said structure can provide temperature difference compensation in colloid foaming process, it is ensured that the heating-up temperature at colloid same level is identical and sufficient, makes colloid expansion rate everywhere keep consistent, reduces difference in thickness, improve the qualification rate of product.
In addition to the implementation, this utility model also includes the technical scheme that other embodiments, all employing equivalents or equivalence substitute mode are formed, within all should falling into this utility model scope of the claims.
