Embodiment

It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these embodiments.

As shown in Figures 1 to 3, the unreeling structure of this compounding machine includes let off roll and motor, is used for coiling on let off roll Raw material, motor are connected to the main shaft of let off roll and can drive its rotation, and let off roll includes three pieces of sections in fan-shaped sub- roller 1, three pieces of sub- rollers 1 are close to the let off roll that cylinder body shape is formed after joining, and mechanism also includes contiguous block, cam disc 2 and shank 3, Described contiguous block side is connected with motor, and the opposite side center rotating of contiguous block is connected to cam disc 2, cam disc 2 Surface offers cam path 4, contiguous block connection cam disc 2 one side be additionally provided with three locating dowels 5, these three locating dowels 5 are surround The center of cam disc 2 is circularly and evenly distributed, and the end of locating dowel 5 is equipped with locating piece 6, and linear is offered on locating piece 6 Locating slot 7, cam path 4 is between locating piece 6 and contiguous block and its cam path 4 is towards locating slot 7, and shank 3 has three difference It is fixed on the side section of sub- roller 1, the locating slot 7 of shank 3 through locating piece 6 is embedded in the cam path 4 of cam disc 2, cam Groove 4 is in " triangular-arc ", and after being rotated to same direction, shank 3 can enter next group of arc from the tail end of previous group arc bar groove The head end of shape bar groove.Contiguous block includes two panels terminal pad 8, is connected between terminal pad 8 by connecting pole 9 and leaves space, wherein Cam disc 2 and locating dowel 5 are connected in one piece of terminal pad 8, the center of another piece of terminal pad 8 is connected with motor, with cam Perforation is offered in the terminal pad 8 that disk 2 and locating dowel 5 connect, cam disc 2 is provided with rotating shaft, and rotating shaft is through the perforation with being connected Disk 8 is rotatablely connected, and rotating shaft tail end, which is provided with, facilitates the handle 10 that personnel rotate to it, and the handle 10 is between two panels terminal pad 8 Space in.

If it is seen that three pieces of sub- rollers 1 be brought into close contact together, be let off roll minimum dimension, and pass through Rotational handle 10, make the concomitant rotation of cam disc 2, be arranged on the shank 3 in cam path 4 due to the shift in position of cam path 4, can produce Raw mobile trend, and shank 3 is located among the locating slot 7 of linear, the direction that shank 3 moves can only be in the locating slot 7 In, the straight line of locating slot 7 by the center of terminal pad 8 towards outwards being extended, so shank 3 now can be with mover roller 1 to the institute of locating slot 7 Rectilinear direction movement, it is in " triangular-arc " to be due to cam path 4, thus three sub- rollers 1 all can synchronously expand outwardly or to Contract, the diameter of let off roll just increases therewith after the sub- relative distension of roller 1, so the design can adjust the diameter of let off roll Size.
