The utility model provides a tension adjusting device for PVC tent cloth. The intermediate air bag is sleeved in the middle of the rotating shaft, the two side air bags are sleeved on the rotating shaft and are located on both sides of the intermediate air bag, the side air bag and the intermediate air bag are arranged in the rubber shell, the two ends of the rubber shell are fixed on the rotating shaft, and the rotating shaft is hollow and has an inflatable tube inside. There are three through holes on the rotating shaft, and the inflatable pipe is provided with three branch pipes through the through hole of the rotating shaft. The three branch pipes are respectively connected with two side air bags and one intermediate air bag. The branch pipe is connected with an electromagnetic valve, the other end is connected with the inflatable end of the inflatable pump, the support plate is fixed on the frame, and the tail of the inflatable pump is rotated and connected with the branch. On the support board, a detection mechanism for detecting whether the fabric conveying is offset is installed on the rack. The device expands the rubber shell by inflating the middle air bag with an air pump, thus providing tension for the fabric. The device can also detect whether the fabric is offset by a detection device, and then adjust the position of the fabric by a side air bag, which is convenient and practical.
【技术实现步骤摘要】
一种PVC篷布的张力调节装置
本技术属于PVC篷布加工设备
,尤其是涉及一种PVC篷布的张力调节装置。
技术介绍
布料加工中,布料是从放卷机构进入生产线,再经多道工序加工后由收卷机构将布料收卷成捆,为保证布料加工时的平整度,需要通过收卷机构或放卷机构处的刹车来控制基布上的张力。在现有技术中,加工时放卷机构的卷径是逐渐变小的,为了保持恒定的张力,不让布料松弛下来,生产时操作工人要不停的调整刹车来保持布料的恒定张力,工艺要求高,操控不方便。
技术实现思路
本技术的目的是提供一种PVC篷布的张力调节装置,该装置通过充气泵对中间气囊充气使橡胶壳膨胀,从而对布料提供张力,还可以通过检测装置检测布料是否偏移,再通过侧气囊调整布料位置,方便实用。本技术的技术方案是:一种PVC篷布的张力调节装置,它包括机架、转轴、圆环状的中间气囊、两个圆环状的侧气囊、可变形的圆筒状的橡胶壳、充气泵,其特征在于,所述的中间气囊套在转轴中部,两个侧气囊套在转轴上且分别位于中间气囊两侧,侧气囊和中间气囊设在橡胶壳内,橡胶壳两端固定在转轴上,所述的转轴中空且内部设有充气管,转轴上开有三个通孔,充气管设有穿过转轴通孔的三根支管,三根支管分别与两个侧气囊和一个中间气囊连通,所述的支管上连接有电磁阀,所述的充气管一端封闭,另一端连接在充气泵的充气端上,机架上固定有支撑板,充气泵的尾部转动连接在支撑板上,所述的机架上安装有检测布料输送是否偏移的检测机构,所述的检测机构包括竖直设置在机架上的凹形安装板、红外线发射器和红外线接收器,红外线发射器安装在凹形安装板上端,红外线接收器安装在凹形安装板下端,布料位于红 ...
