摘要： A belt press has horizontally extending and vertically spaced upper and lower plates defining a horizontally extending gap, vertically spaced upper and lower upstream drums rotatable about respective horizontal drum rotation axes at the upstream press end, and vertically spaced upper and lower downstream drums rotatable about respective horizontal drum rotation axes at the downstream press end. Each of the downstream drums is supported for at least limited pivoting about a vertical axis generally intersecting the respective drum rotation axis. Upper and lower endless belts spanned over the respective upper and lower drums each have a working stretch lying between the plates and a return stretch. Upper and lower pairs of horizontally spaced outer adjustment rollers rotatable about respective horizontal axes fixed each engage the respective working stretch in a predetermined vertical direction and respective upper and lower central adjustment rollers positioned between the respective outer rollers engage the respective working stretch in a vertical direction opposite to the respective outer rollers. Each central adjustment roller can pivot about a horizontal axis generally centrally passing perpendiculary through the respective central adjustment roller. Sensors detect the position of the belt transversely of the direction and a controller pivots the drums and central adjustment rollers about the respective adjustment axes in response to the respective detected belt position.
摘要翻译： 带式压榨机具有水平延伸且垂直间隔的上板和下板，其限定水平延伸的间隙，垂直间隔的上和下上游滚筒可在上游加压端处围绕相应的水平滚筒旋转轴线旋转，并且垂直间隔开的上下滚筒可相对于 下游压机端的水平滚筒旋转轴。 每个下游滚筒被支撑为围绕通常与相应滚筒旋转轴线相交的垂直轴线的至少有限的枢转。 跨越相应的上鼓和下鼓的上和下环形带各自具有位于板之间的工作拉伸和返回拉伸。 可相对于固定的相应水平轴线旋转的上下对的水平间隔的外调节滚子在预定的垂直方向上接合相应的工作拉伸，并且位于相应的外滚子之间的相应的上下中央调节滚子在垂直方向上接合相应的工作拉伸 与相应的外辊相对。 每个中央调节辊可围绕水平轴线枢转，大致中心地通过相应的中央调节辊通过中心通过。 传感器检测带横向方向的位置，并且控制器响应于相应的检测到的皮带位置围绕相应的调节轴使滚筒和中央调节辊枢转。
