Description

Method for automatically spraying capsule isolating agent for tire vulcanizing device

Technical Field

The invention relates to the field of tire production, in particular to a method for automatically spraying a capsule isolating agent for a tire vulcanizing device.

Background

As is known, the process of tyre vulcanisation consists in placing a green tyre in a heated mould, the inside of which is then filled with a vulcanisation medium to provide pressure and heat by means of a bladder mounted in a central mechanism. In order to prevent the green tire from being stuck to the bladder during vulcanization, a release agent needs to be applied between the green tire and the bladder.

At present, various tire manufacturers commonly adopt an internal spraying device to spray a separant in advance inside a green tire, and a few manufacturers also adopt a method of spraying the separant on the outer surface of a capsule. With the internal spraying method, the release agent is often sprayed on the outer surface of the capsule. And the continuous automatic production of the tire needs to be interrupted when the isolating agent is sprayed in the capsule, and the spraying is carried out manually after the machine is stopped, so that the production efficiency is influenced, and the workload of operators is increased.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides a method for automatically spraying a capsule isolating agent for a tire vulcanizing device, which solves the problems that the production efficiency is influenced and the workload of operators is increased because the continuous automatic production of tires needs to be interrupted when capsules are manually sprayed.

The technical scheme adopted by the invention for solving the technical problems is as follows: a method for automatically spraying a capsule isolating agent for a tire vulcanizing device is characterized in that a supporting mechanism is arranged on the outer side of a lower hot plate at intervals and used for supporting a rotary ring, the rotary ring can rotate in the circumferential direction under the driving of a driving mechanism, supports with adjustable heights are arranged above the rotary ring at intervals, a nozzle is arranged on each support, the nozzle is adjusted to a proper height according to the specification of the capsule when the tire production specification is changed every time, and the nozzle is connected with an isolating agent pipe and a corresponding compressed air pipe;

in the tire production process, the MES system automatically suspends the loading of the green tire according to the frequency and the spraying parameters set by the control software after the vulcanization of the corresponding tire is finished, and starts the spraying process;

the reciprocating ring rotates clockwise to a set angle under the driving of the driving mechanism, meanwhile, the nozzle rotates the same angle along with the reciprocating ring, the capsule is sprayed according to set parameters, after the spraying is finished, the reciprocating ring rotates anticlockwise to the original position, the next spraying process is waited, and the tire production continues; the rotating ring rotates anticlockwise, and meanwhile, the nozzle is automatically cleaned by compressed air.

The invention can also be realized by the following measures:

the MES system controls the spraying time, the spraying amount, the spraying air pressure, the rotating angle of the reciprocating ring and the nozzle self-cleaning time according to set parameters.

The spraying process is inserted between the two tire production processes.

The part of the supporting mechanism contacted with the rotary ring is lined with materials convenient for the sliding of the rotary ring, and the upper end of the supporting mechanism is provided with a roller.

The invention has the advantages of solving the problems that the continuous automatic production of the tire is interrupted when the capsule is manually sprayed, not only influencing the production efficiency, but also increasing the workload of operators, and achieving the purposes of improving the efficiency and reducing the workload.

Detailed Description

In the figure, a plurality of supporting mechanisms 1 are arranged outside a lower hot plate 7 of a tire vulcanizing device and used for supporting a revolving ring 5, materials which are convenient for the revolving ring 5 to slide are lined at the contact part of the supporting mechanisms 1 and the revolving ring 5, and rollers are arranged at the top ends of the supporting mechanisms 1, and the revolving ring 5 can rotate along the circumferential direction under the drive of a driving mechanism 2. Four sets of height-adjustable supports 4 are arranged above the revolving ring 5, the nozzle 3 is arranged on the supports 4, the nozzle 3 is adjusted to the proper height according to the specification of the capsule 6 so as to adapt to the change of the capsule height every time the tire production specification is changed, and the nozzle 3 is connected with an isolating agent pipe and a corresponding compressed air pipe.

Aiming at capsules of various specifications, parameters such as spraying frequency, spraying amount, spraying air pressure, rotating angle of the rotary ring 5, self-cleaning time of the nozzle 3 and the like which are suitable for experiments and summaries are stored in an MES system.

The MES system sends various parameters required by spraying to a control system of the tire vulcanizer along with other necessary parameters, and automatically suspends the loading of the green tire and starts the spraying process according to the frequency and the spraying parameters set by the control system in the production process of the tire after the corresponding vulcanization period is finished. The spraying time, the spraying amount, the spraying air pressure, the rotating angle of the rotating ring, the self-cleaning time of the nozzle and the like can be automatically implemented according to the parameters issued by the MES.

The reciprocating ring 5 rotates clockwise to a set angle under the driving of the driving mechanism 2, and simultaneously the nozzle 3 rotates along with the reciprocating ring 5 by the same angle, and the capsule 6 is sprayed according to set parameters. After the spraying is finished, the reciprocating ring 5 rotates anticlockwise to the original position, the next spraying process is waited, and the tire production is continued. The spraying process is inserted between two automatic production processes, the automatic production process does not need to be interrupted, and the rotating and reciprocating ring 5 rotates anticlockwise and simultaneously automatically cleans the nozzle by compressed air.
