Description
Technical Field
The invention relates to a technology for smearing a release agent on an outer tire curing bladder, in particular to a method and a tool for smearing the release agent on the surface of the curing bladder.
Background
The shape of the green tire is the same as that of the tire, the green tire is manufactured on a forming machine and then is conveyed to a vulcanizing machine for vulcanization to obtain the tire, and a vulcanization capsule is one of main components of the vulcanizing machine and participates in the vulcanization process. Before the vulcanization of the green tire, a release agent, namely a release agent, needs to be sprayed in the green tire, and the release agent has the functions of preventing the tire from being adhered to a vulcanization capsule after the vulcanization and ensuring that the vulcanized tire has better appearance and performance.
Currently, spray release agents come in two forms:
1. before vulcanization, a separant is sprayed in the green tire in a centralized way, and the method has the advantages of uniform spraying and the defects of increased working procedures for manufacturing the outer tire and prolonged period for manufacturing the sulfur tire; the spraying process occupies a large area, increases transportation, increases environmental pollution and the like;
2. the vulcanizing procedure is that the isolating agent is manually brushed and coated on the vulcanizing capsule, and the mode has the advantages of saving procedures, places, labor and the like in relative centralized spraying; the defects that manual brushing is time-consuming, has certain influence on vulcanization capacity, has certain influence on the quality of the outer tire due to uneven brushing, and does not guarantee the safety of brushing personnel in a high-temperature environment.
Disclosure of Invention
Aiming at the advantages and disadvantages of the two spraying processes, the invention is used for the spraying process in the vulcanization process, the isolating agent is sprayed in the curing bladder coating tool by an operator outside a vulcanization hot mold (at normal temperature), then the curing bladder coating tool is sleeved outside the curing bladder, and the curing bladder is fully contacted with the coating tool by manually operating a machine table, so that the purpose that the capsule is coated with enough isolating agent is achieved. The method is simple, time-saving and easy to operate, and the safety of personnel is guaranteed.
In order to solve the technical problem, one embodiment of the present invention adopts the following technical solutions:
a curing capsule separant smearing tool comprises end part circle frameworks, a tightening layer, an isolating layer and an isolating agent adsorption layer, wherein the two end part circle frameworks are respectively positioned at the upper end and the lower end of the tool; the tightening layer, the isolating layer and the isolating agent adsorption layer are sequentially arranged from outside to inside and are in close contact with each other; the inner side of the isolating agent adsorption layer is provided with a cambered surface which can be attached to the surface of the vulcanization capsule during expansion.
The end circle framework is made of steel wires. The steel wire ring mainly plays a role in tooling shaping and connection of various materials.
The lacing layer is made of a cord yarn. The cord yarn mainly plays a role in tightening the outside of the tool, and enables the isolating agent adsorption layer (felt) to be in full contact with the vulcanized rubber bag when the vulcanized rubber bag expands.
The isolation layer is made of rubber. The isolating layer mainly isolates the isolating agent in the felt from the outside of the tool, so that the isolating agent does not leak.
The isolating agent adsorption layer is made of felt. The felt mainly plays a role of an adsorption release agent.
The method for coating the release agent on the surface of the curing bladder by using the tool comprises the steps of coating the release agent on the release agent adsorption layer in the tool outside a curing operation production line, then sleeving the tool on the curing bladder, inflating and expanding the curing bladder, fully contacting the surface of the curing bladder with the release agent adsorption layer, then deflating and shrinking the curing bladder, and taking down the tool.
Compared with the prior art, the invention has at least the following beneficial effects: by adopting the tool, the separant is brushed on the felt at normal temperature, and then the separant is uniformly smeared on the surface of the vulcanized rubber bag in a reverse sticking mode, so that the operation efficiency is improved, the separant smearing effect is ensured to be uniform, and an operator does not need to brush the separant on a high-temperature vulcanization production line, so that high-temperature scalding can be avoided.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in FIG. 1, the curing bladder release agent application tool is similar to a drum in shape, but is hollow in the middle and can be sleeved on a curing bladder.
As shown in fig. 2, the curing capsule release agent smearing tool is composed of a steel wire ring 1, a cord layer 2, a rubber seal layer 3 and a felt layer 4, the two steel wire rings are respectively located at the upper end and the lower end of the tool, the cord layer 2, the rubber seal layer 3 and the felt layer 4 are arranged between the two steel wire rings 1, and the two ends of the cord layer 2, the rubber seal layer 3 and the felt layer 4 are respectively connected to the two steel wire rings 1, so that the cord layer 2, the rubber seal layer 3 and the felt layer 4 are all encircled to form a spherical surface between the two steel wire rings 1; the curtain yarn layer 2, the glue seal layer 3 and the felt layer 4 are sequentially arranged from outside to inside and are in close contact; the inner side of the felt layer 4 is provided with a cambered surface which can be attached to the surface of the vulcanization capsule during expansion.
The steel wire ring mainly plays a role in tooling shaping and connection of various materials. The curtain yarn mainly plays a role in tightening the outside of the tool, and the felt can be fully contacted with the vulcanized rubber bag when the vulcanized rubber bag expands. The glue seal layer mainly isolates the isolating agent in the felt from the outside of the tool, so that the isolating agent does not leak. The felt mainly plays a role of an adsorption release agent.
The tool is applied to the outer tire vulcanizing capsule to paint the separant, the two modes of spraying the separant inside a vulcanized raw tire or brushing the separant on a high-temperature vulcanizing capsule are replaced, the separant is painted inside the tool, the separant is reversely pasted on the vulcanizing capsule by the tool, the separant is painted on the tool once, the vulcanizing capsule can be reversely pasted for many times, and therefore the efficiency of evenly painting the separant on the vulcanizing capsule is improved.
Specifically, the step of coating the isolating agent on the surface of the curing bladder by using the tool is that the isolating agent is coated on the felt layer inside the tool firstly outside a curing operation production line (no high temperature exists, so that the curing operation is safer for operators), then the tool is sleeved on the curing bladder like a green tire, then a manual shaping button of a vulcanizing machine is operated to inflate and expand the curing bladder, the surface of the curing bladder is fully contacted with the felt layer under the constraint of a cord yarn layer outside the tool, the isolating agent on the felt is uniformly attached to the outer surface of the bladder, the tool is taken out when the curing bladder contracts inwards and then sleeved on the curing bladder on a second layer to be sequentially operated, or the tool is taken down after the curing bladder is deflated.
