High-pressure hose linkage feeding device

The utility model discloses a high-pressure hose linkage feeding device. The high-pressure hose linkage feeding device is composed of more than one support rolls which are arranged on the horizontal plane, has the same height and are used to support a tube core/high-pressure hose semi-finished product, wherein the support rolls are arranged on the same straight line; and each support roll is composed of a support of which height is adjustable and a roller which is arranged on the top of the support and can rotate. The high-pressure hose linkage feeding device is low in manufacturing cost and does not require extra motive force, thus the processing cost can be saved; and the height of the support rolls is adjustable, thus the feeding demand of the tube cores/high-pressure hose semi-finished products in different positions can be met.
