Description

A kind of vulcanizing tank gum cover structure for detecting leakproofness
Technical field
The utility model relates to vulcanizing tank technical fields, refer specifically to a kind of vulcanizing tank gum cover structure for detecting leakproofness.
Background technique
Vulcanizing tank is in rubber product production using earliest vulcanizing equipment, although other vulcanizing equipments have very greatly for many years Development, but until the vulcanization of certain rubber products today (sebific duct, rubber overshoes, rubber roller) also be unable to do without it, it is exactly mechanograph, adhesive plaster system Product box cable product also has using sulfurizing pot vulcanization, currently, vulcanizing tank is still one of basic equipment of vulcanization.
Existing adhesive tape vulcanizing, such as V band, automobile synchronous belt, automobile multi-wedge belt, industry relatively mostly use vulcanizing tank with processing Vulcanized.The vulcanization of so-called adhesive tape is that the vulcanization plant equipped with sulfureted adhesive tape is placed in vulcanizing tank, utilizes high pressure Steam, in the time of process stipulation, temperature, under pressure, sulfidization molding selects mold as product for vulcanization plant Molding internal model is set with gum cover by adhesive tape cover in the internal model outside adhesive tape, then the both ends of gum cover install upper cover plate into Row sealing, is put into thereafter in vulcanizing tank and carries out differential pressure curing, while into vulcanizing tank and being passed through steam in mold, in the outer of gum cover Portion forms external pressure, internal pressure is formed in mold, adhesive tape at high temperatures and pressures, pattern is generated because of viscosity flow and cross-linking reaction occurs Vulcanization is completed, hangs out, demould again after the completion of vulcanization, cutting and obtain finished product.Effect of gum cover one is in gum cover during its Under the action of lock ring, since the pressure being transported in pressure vessel is greater than the pressure being transported in barrel-shaped mold, make adhesive tape to Mold direction squeezes, the adhesive tape of the specific pattern of generation;When another effect is pressurization, between barrel-shaped mold and pressure vessel Sealing function is played, the pressure in pressure vessel is made to be greater than the pressure in barrel-shaped mold.If gum cover sealing is bad, glue will cause Material is scrapped.
To solve the above-mentioned problems, people attempt to improve the tightness of gum cover.As number of patent application is One kind disclosed in the patent of invention " gum cover for vulcanizing driving belt " of CN200910064967.5 (notification number CN101554759A) Gum cover for vulcanizing driving belt, the gum cover are one barrel-shaped, and upper and lower ends are open, and circle sealing lip is respectively arranged in both ends of the surface, reduces Gum cover because height is pressurized the contraction distortion generated, increases the effective cutting width of adhesive tape in use.
Although the above method can be improved the service life of gum cover, the leakproofness of gum cover not only depends in sulfidation In the performance of itself, the external conditions such as sulfuration process are additionally depended on, therefore detect the leakproofness tool of gum cover in time before vulcanization It is of great importance.

S15, vulcanizing tank are uncapped: being opened top cover 2, hung out mold 32.
The working principle of the utility model is as follows: internal pressure chamber a1 promotes vulcanization into stripping heating load;External pressure chamber a2 into vapour with Pressure difference is formed between internal pressure chamber a1, then mating mold completes the molding of adhesive tape, sentences by the detection of the pressure to internal pressure chamber a1 Disconnected gum cover 33 whether gas leakage;
(1) for the first control method, external pressure chamber a2 is into after vapour, reaching in lower setting value soon carries out Press chamber a1 into vapour, efficiency is higher;Internal pressure inlet valve 351 can be closed into reaching setting value after vapour in internal pressure chamber a1, if gum cover 33 There is no gas leakage, the pressure of internal pressure chamber a1 then remains unchanged, if 33 gas leakage of gum cover, the gas of external pressure chamber a2 can enter internal pressure chamber a1, The pressure of internal pressure chamber a1 can be increased further.But gas leakage situation if it exists, internal pressure is completed into vapour when detecting the situation Step, therefore there are two problems: first, sizing material is local vulcanized and causes waste product;Second, waste interior pressurized air source;
(2) for second of control method, external pressure chamber a2 first detects the variation of internal pressure chamber a1 pressure into after vapour, if Gum cover 33 does not have gas leakage, since external pressure chamber a2 can generate heat into vapour, so that vulcanizing tank bulk temperature increases, therefore internal pressure chamber a1 Pressure also can be slightly elevated, if 33 gas leakage of gum cover, the gas of external pressure chamber a2 can enter internal pressure chamber a1, the boosting speed of internal pressure chamber a1 Degree can increase significantly.Therefore gas leakage situation if it exists, internal pressure chamber a1 is not completed also into vapour step, Ke Yiyou when detecting the situation Effect avoids above-mentioned two problems.But the disadvantages of this method is that curing efficiency is lower, because vulcanization reaction need to be in internal pressure chamber a1 It is completed after into vapour.
The present invention is not limited to above-mentioned specific embodiment, all within the spirits and principles of the present invention, made any Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
