Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pressure rollers for tire production, and more specifically to an integrated device integrating a pressure proportional valve and a plurality of pressure rollers. Background Art
[0002] The multi-piece pressure rollers of the tire building machine are divided into multiple pressure zones, which cooperate with the pressure proportional valve that controls them. According to the pressure setting of the formula library at the control end of the building machine, the various components of the tire are automatically fitted and pressed tightly; the multi-piece pressure rollers are installed on the multi-piece pressure roller mounting bracket, and the pressure proportional valve that controls them is installed on the remote building machine frame, and multiple pressure zone air pipes with a long distance (2 to 8 meters) are used to connect them.
[0003] With the control accuracy requirements of tire manufacturing, the pressure zones of multiple rollers tend to increase. The long-distance connection of up to 16 or more pressure zone air pipes requires consideration of the air pipe connection channel, and because the multi-piece roller mounting bracket is a moving part, the air pipe needs to reserve a moving length, making the appearance of the multi-piece roller part of the molding machine complicated; there is a risk of misconnection when multiple pressure zone air pipes are connected to the pressure zone air inlet of the multi-piece roller, and once misconnected, it is not easy to detect, and the pressure control of the multi-piece roller will be used incorrectly, affecting the molding quality of batch tires; the pressure proportional valve is connected to the long-distance pressure zone air pipe of the multi-piece roller, and the air pipe cavity volume accounts for a large proportion of the total use volume (often larger than the multi-piece roller piston volume). When the multi-stage pressure is switched during the tire molding rolling process, the actual pressure switching accuracy will be greatly reduced. If the production frequency of the tire molding machine needs to be increased, this is a major constraint; the pressure proportional valve has a real-time pressure display, and the remote installation cannot intuitively correspond to the multi-piece roller zone that can be controlled. The utility model proposes a new solution to the above problems. Utility Model Content
