Problems solved by technology

[0002] The bladder shaping vulcanization process is widely used in the tire manufacturing industry. The following problems are prone to occur in the prior art: (1) the pressure in the bladder will change during the storage process after the green tire is shaped; (2) the storage process after the bladder is shaped The shape of the middle tire blank is easy to change, resulting in uneven or excessive stretching of the cord; (3) The pressure fluctuations in the capsule reduce the number of times the capsule is used
(4) The pressure in the capsule is too low, the capsule is not fully stretched, and it is easy to cause discounts during the vulcanization process
(5) When the pressure of the capsule is too high, the aging of the rubber will be accelerated due to the overstretching of the capsule, which will affect the service life of the capsule

Abstract

An automatic pressure-maintaining system for capsule shaping, including a capsule fixture. The capsule fixture is provided with a water inlet and a water outlet. The water inlet is connected to the water inlet pipe through a hollow plug. The water inlet pipe is provided with a pressure gauge and a one-way overflow valve. ; The water outlet is communicated with the water outlet pipe through a hollow plug, and a one-way overflow valve is also arranged on the water outlet pipe. The invention solves the problem that the pressure in the capsule changes during the storage process after the tire blank is shaped; it ensures that the shape of the tire blank does not change during the storage process after the capsule is shaped, ensures the stretching and shaping of each part, and effectively prevents the cord from stretching Uneven or excessive stretching; eliminate pressure fluctuations in the capsule and effectively increase the number of times the capsule is used. The internal and appearance quality defects of the tires thus produced are completely controlled, and the quality of the tires is further improved.

Description

technical field [0001] The invention relates to an innovative bladder shaping automatic pressure maintaining system, which can automatically maintain the required inner air pressure of the bladder after the tire blank is shaped. Background technique [0002] The bladder shaping vulcanization process is widely used in the tire manufacturing industry. The following problems are prone to occur in the prior art: (1) the pressure in the bladder will change during the storage process after the green tire is shaped; (2) the storage process after the bladder is shaped The shape of the middle tire blank is easy to change, resulting in uneven or excessive stretching of the cord; (3) The pressure inside the capsule fluctuates, which reduces the number of times the capsule is used. (4) When the pressure inside the capsule is too low, the capsule is not fully stretched, and it is easy to cause discounts during the vulcanization process. (5) When the pressure of the capsule is too high, ...
