"upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
Fig. 1 is a front sectional view of an elbow winding machine according to the present utility model, and fig. 2 is an enlarged view of an elbow winding machine a according to the present utility model, as shown in the drawings, which includes a winding mechanism and a driving mechanism. The pneumatic assembly 4 of the driving mechanism is positioned at the top end of the first frame 1 of the winding machine, the first mounting clamp 5 connected with the pneumatic assembly 4 is matched with one end of the elbow 6, and the second mounting clamp 7 connected with the other end of the elbow 6 is connected with the second frame 2 of the winding machine. The first rack 1 is connected with an arc-shaped rack 3 of the driving mechanism, and the arc-shaped rack 3 is matched with an arc-shaped moving groove of the driving box 8. The part of the arc-shaped rack 3 in the driving box 8 is meshed with a first gear 10 in the driving box 8, and a second gear 11 on one side of the first gear 10 is meshed with a first toothed ring 12 at the edge of a winding mechanism mounting seat 13. The center of the mounting seat 13 is hinged with the elbow 6, and the extrusion head 9 communicated with the raw material cavity 14 on one side of the mounting seat 13 is in sliding connection with the rotating groove of the driving box 8.
The winding mechanism winds polyethylene on the outer side wall of the elbow 6, and the driving mechanism drives the winding mechanism to move along the elbow 6, so that polyethylene is wound on the side wall of the elbow 6. When the first mounting clamp 5 and the second mounting clamp 7 are connected with the elbow 6, the first motor is started, and the first gear 10 drives the driving box 8 to move along the arc-shaped rack 3. The second motor 15 is started, the second gear 11 drives the mounting seat 13 to rotate through the first gear ring 12, and further the extrusion head 9 rotates relative to the elbow 6, so that the winding polyethylene on the side wall of the elbow 6 is uniformly and tightly realized.
