Detailed Description
As shown in fig. 1 and 2, the wall plastering machine with the chain tensioning device of the embodiment includes a main machine frame 1, a driving wheel 4 driven by the output of a motor, a driven wheel 5 for driving a wall plastering mechanism to ascend and descend, and a transmission chain 6 connected between the driving wheel and the driven wheel; the plastering machine with the chain tensioning device also comprises at least 2 tensioning chain wheels 2; in the present embodiment, a 2-tensioner sprocket 2 design is employed; each of the tension sprockets 2 comprises an oscillating member 21 and a sprocket body 22; one end of the swinging piece 21 is coaxially connected with the circle center of the chain wheel body 22, the chain wheel body 22 can rotate around the shaft, after the swinging piece 21 is connected with the tensioning chain wheel body 22, the chain wheel body 22 can still rotate around the circle center, the other end of the swinging piece 21 is coaxially connected with the main machine frame 1, and the swinging piece 21 can rotate around the shaft; the 2 tension chain wheels 2 are respectively positioned at two outer sides of the transmission chain 6. The 2 tension chain wheels 2 are connected through an elastic connecting piece 3, and two ends of the elastic connecting piece 3 are respectively connected to the swinging pieces 21 of the two tension chain wheels 2. The outer wheel circumferences of the chain wheel bodies 22 of the 2 tensioning chain wheels 2 are not respectively pressed on the outer side surfaces of the transmission chains 6. The acting force generated after the elastic connecting piece 3 is connected with the 2 tensioning chain wheels 2 is pulling force. Because one end of the swinging piece 21 is coaxially connected with the circle center of the chain wheel body 22 of the tension chain wheel 2, when the tension chain wheel 2 is matched with the transmission chain 6, the chain wheel body 22 rotates in a way of being matched with the transmission chain 6, and the rotation action of the chain wheel body 22 cannot be limited by the swinging piece 21.
