Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire processing technology, specifically to a tire tread rubber hot pressing device for tire processing. Background Technology
[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are typically mounted on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and guaranteeing vehicle performance. Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and extreme temperatures during operation. Therefore, they must possess high load-bearing capacity, traction, and cushioning performance, while also requiring high wear resistance and flexural strength, as well as low rolling resistance and heat generation. The tread compound is the outermost layer of rubber in contact with the road surface, with its patterned surface. It provides traction, cushions impacts and sway during driving, and prevents the cord layers from being cut or punctured. The tread compound requires a hot-pressing device during processing.
[0003] In the existing technology, conventional tread rubber hot pressing devices cannot directly detect the pressure of the pressure roller, resulting in uncontrollable hot pressing pressure and poor hot pressing quality. Furthermore, the temperature of the pressure roller cannot be adjusted during the hot pressing process, leading to uncontrollable hot pressing quality. In addition, unpleasant odors are generated during the hot pressing process, causing environmental pollution and making the device environmentally unfriendly. Utility Model Content

[0034] Specifically, the guiding mechanism 11 includes a second electric telescopic rod 111 and a guide plate 112. The second electric telescopic rod 111 is installed on the lower side of the side wall of the mounting frame 2, and the guide plate 112 is fixedly installed on the output shaft of the second electric telescopic rod 111.

At this time, the output shaft of the first electric telescopic rod 301 in the first lifting mechanism 3 drives the rectangular plate 302 to move up and down, causing the rectangular plate 302 to drive the rectangular box 6 on the lower surface of the pressure sensor 4 to move downward. The rectangular box 6 drives the pressure roller 8 downward through the air distribution mechanism 7, and the pressure roller 8 heat-presses the tread compound. The pressure sensor 4 detects the pressure of the pressure roller 8 and feeds the information back to the control box 501 in the control mechanism 5. When the pressure is greater than or less than the set value, the control box 501 triggers the alarm 502, which allows the operator to adjust the pressure of the pressure roller 8 in time to ensure that the pressure of the pressure roller 8 is moderate and improve the heat pressing quality. Then, the exhaust fan in the heating mechanism 9... 902 The gas in the front gas distribution box 701 is drawn into the electric heating box 903 through the conduit 901. The electric heating box 903 heats the drawn gas. The heated gas flows into the rear gas distribution box 701 through the conduit 901. The hot gas in the rear gas distribution box 701 enters the air intake channel 705 on the left side of the gas distribution box 701 through the air inlet 707, and then enters the pressure roller 8 through several air inlets 707 on the front side. The gas in the pressure roller 8 flows into the air return channel 706 through the air return hole 708, and then flows into the front gas distribution box 702 through the front air return hole 708. 01, enabling gas circulation and temperature regulation of the pressure roller 8, ensuring the hot pressing temperature meets the requirements and further improving the hot pressing quality. The turbine fan 104 in the purification mechanism 10 draws air from the air purifier 103, creating a negative pressure inside the air purifier 103, which then draws air from the dust collection hood 101 through the connecting pipe 102. The dust collection hood 101 draws in the gas corresponding to the lower surface of the rectangular box 6, and the air purifier 103 purifies the gas, increasing the purification function for unpleasant odors and making it more environmentally friendly.
[0039] In summary, this tire tread rubber hot pressing device adds a pressure monitoring function for the pressure roller 8, allowing for direct viewing of the pressure of the pressure roller 8, ensuring that the pressure of the pressure roller 8 is moderate, improving the hot pressing quality, and also enabling the temperature of the pressure roller 8 to be adjusted to meet the hot pressing requirements. It also adds a purification function for unpleasant odors, making it more environmentally friendly to use.
