Coiled material feeding device

Abstract

The invention relates to the field of construction machinery, and discloses a coiled material feeding device. The coiled material feeding device comprises a follow-up shaft, a first fixing seat, a second fixing seat and a pushing ring, wherein the follow-up shaft is sleeved with a paper tube used for coiling coiled materials; the first fixing seat is arranged at one end of the follow-up shaft; thesecond fixing seat is arranged at the other end of the follow-up shaft; and the pushing ring is arranged between the first fixing seat and the follow-up shaft and can move in the axis direction of the follow-up shaft, an elastic piece is arranged between the first fixing seat and the pushing ring, and under the action of the elastic piece, the pushing ring presses the paper tube between the pushing ring and the second fixing seat all the time. The coiled material feeding device can lock the paper tube in the axial direction, and the positioning precision of repeated coiled material feeding isguaranteed.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a coil feeding device. Background technique [0002] In the field of construction, the roll feeding of wallpaper or other windable flexible materials is generally fed by a motor, or the roll is placed naturally, and the follow-up mechanism provides pulling power for feeding. In the general construction site environment, due to the relatively complicated mechanical structure of the motor feeding, the control difficulty and maintenance cost are high, so it is difficult to use it on a large scale. Although the feeding method of naturally placing the reel has a simple structure and low maintenance costs, it has a great impact on the construction quality due to the low repeat positioning accuracy of the reel and the coiled material. [0003] How to ensure the positioning accuracy of repeated coil feeding is a technical problem to be solved by those skilled in the art. ...
