Abstract
The invention relates to a temperature difference compensation foaming furnace. The temperature difference compensation foaming furnace comprises a box, multiple radiating assemblies are uniformly arranged in the horizontal width direction in a bubble generating region in the box, and each radiating assembly is composed of 2-3 aluminum fin radiating pipes; multiple temperature compensating devices independent of one another are arranged corresponding to the multiple radiating assemblies and conduct heating operation according to preset heating temperature. The foaming furnace can provide temperature difference compensation in the colloid foaming process and ensure that heating temperatures at the same horizontal position of colloid are the same, and the colloid is heated sufficiently; expansion rates of all positions of the colloid are kept consistent, the thickness difference is reduced, and the product yield is increased.
Description
Technical field
The invention belongs to the foaming furnace of macromolecular material foaming, be specifically related to a kind of vertical-foaming stove.
Background technology
Foaming furnace foaming PVC colloid can be used in PVC foam leather production process, foaming furnace adopts high-temperature catalytic ADC blowing agents to produce gas, gas is utilized to make the PVC glue material inside of molten condition produce a large amount of stingy abscess, along with the prolongation of time, crafters increases increase gradually makes PVC colloidal volume expansion several times even tens times, adopts cooling press flower process to form various PVC foam leather subsequently.
In industrial production, the general foaming furnace adopted can be divided into vertical (console mode) and box (ground-above type), each producer choice for use according to actual needs.With regard to vertical-foaming stove, due to its inner special design, the radiator that furnace heat is corresponding is all arranged on more than body of heater center line, by thermal cycle pipeline by heat blow to PVC leather top and bottom.Temperature Distribution in existing vertical-foaming stove casing 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 subject to the impact of temperature very large, the fast gas forming amount of temperature overactivity is large, otherwise then slow then little.So just make the expansion rate of PVC leather same level line occur different, cause the uneven thickness of leather.
In addition, in PVC semifinished leather products manufacturing process, be subject to the impact of equipment and operating personnel's mode of operation, PVC foam can produce difference in the same horizontal line, makes end article not meet the uniform production standard of thickness.
Summary of the invention
Technical problem to be solved by this invention provides a kind of foaming furnace for above-mentioned prior art, arrange by improving heating, guarantee the even and steady of wind pushing temperature, solve because the temperature difference causes the difference of colloid expansion rate in PVC foam process, the qualification rate of raising foaming product.
The present invention's adopted technical scheme that solves the problem is: a kind of temperature difference compensation foaming furnace, comprise casing, gas bubble generating area in casing, evenly arranges some groups of radiating subassemblies along horizontal width direction, often organizes radiating subassembly and 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.
Comparatively reasonably arranging is that the default heating-up temperature of some described benefit temperature devices is identical.
Compared with prior art, the invention has the advantages that: the foaming furnace providing a kind of improvement, temperature difference compensation can be provided in colloid foaming process, guarantee that the heating-up temperature at colloid same level place is identical and sufficient, colloid expansion rate is everywhere 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 the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figure 1, temperature difference compensation foaming furnace in the present embodiment, comprise casing 1, the right and left of casing 1 is provided with needle plate 2, gas bubble generating area in casing 1 and high-temperature heating district, evenly arrange three groups of radiating subassemblies along horizontal width direction, radiating subassembly is arranged in left, center, right three place of casing, often organizes radiating subassembly and is made up of 2 aluminum fin-stock radiating tubes 3; Corresponding three groups of radiating subassemblies arrange three groups of separate benefit temperature devices (not shown in FIG.) again, mend warm device and carry out heating operation according to default heating-up temperature and three groups of default heating-up temperatures of mending warm device are identical.
The foaming furnace of said structure can provide temperature difference compensation in colloid foaming process, guarantees that the heating-up temperature at colloid same level place is identical and sufficient, and colloid expansion rate is everywhere consistent, and reduces difference in thickness, improves the qualification rate of product.
In addition to the implementation, the present invention also includes other embodiments, the technical scheme that all employing equivalents or equivalent substitute mode are formed, within the protection domain that all should fall into the claims in the present invention.
