Problems solved by technology
Because of the narrow pressure roller, when pressing the middle of the tread, the edge of the tread (shoulder part) will be lifted due to no force, and the pressure roller is pressed to this part (shoulder part). ), it is necessary to increase the pressing pressure and pressing time to ensure the pressing quality, resulting in the disadvantages of excessive pressing and waste of time
During the axial movement of the pressure roller, because the pressure roller is narrow, the pressure is high and the axial movement is slow, there will be a certain axial pressure on the tread, resulting in the disadvantage of the tread rubber being concentrated on the tire shoulder.

The invention relates to a tread compression roller device in tire forming working procedure, and belongs to the field of rubber machinery. The tread compression roller device is provided with a rear compression roller, and is characterized in that a roll shaft of the rear compression roller is connected with a telescopic link of an air cylinder; a cylinder body of the air cylinder is fixed on a rear compression trolley through a bracket; the rear compression trolley is arranged on a rear compression slideway; the rear compression trolley is provided with another air cylinder through a fixed bracket; an air cylinder piston rod of the another air cylinder is connected with a precompression roll shaft through a fixed rack; and two precompression rollers are sleeved on the precompression roll shaft. The tread compression roller device is simple in structure, the tread press-fitting efficiency is improved, and more importantly, the pre-fitting quality of the tread shoulder is promoted.
Description
technical field [0001] The invention relates to the field of tire building machinery, in particular to a tread pressure roller device in the tire building process. Background technique [0002] As we all know: the tread of a tire is like the sole of a leather shoe, and it is the key component that directly contacts the ground. Tread pressing technology is like pressing the glued sole on the shoe firmly, and it is the key technology to ensure the solid and durable tire tread. [0003] The pressing roller used in the current tread pressing technology is a narrow side pressing roller, and the whole pressing process of the tread is completed by relying on the axial movement of the pressing roller and the rotation of the tire. Because of the narrow pressure roller, when pressing the middle of the tread, the edge of the tread (shoulder part) will be lifted due to no force, and the pressure roller is pressed to this part (shoulder part). ), it is necessary to increase the pressi...
