Detailed Description
The following detailed description of embodiments of the utility model is provided in conjunction with the accompanying drawings:
as shown in the figure, the relay power shaft system for the coating machine comprises a frame 1, a driving roller 2, a pair of driven rollers 3, a vacuumizing device 4 and a driving device. Two ends of a driving roller 2 and a pair of driven rollers 3 are respectively rotatably supported on the frame 1 by bearings, the driven rollers 3 are symmetrically distributed on two sides of the driving roller 2 and are parallel to the driving roller 2, and a material passing gap is reserved between the driven rollers 3 and the driving roller 2 and does not exceed the thickness of the material belt. For coating machines producing material belts with different thicknesses, bearing blocks at two ends of the driven roller 3 can be supported on the machine frame 1 in a sliding mode through the rails 5, and the gap can be adjusted conveniently. The material belt 10 enters from the gap between the main roller 2 and one of the driven rollers 3 and winds out from the lower part of the main roller 2 to form contact with the outer wall of the main roller 2, and finally penetrates out from the gap between the main roller 2 and the other driven roller 3.
In order to draw the material belt 10, the driving roll 2 adopts a hollow roll design, one end of the driving roll 2 is connected with a driving mechanism-speed reducer, and the other end of the driving roll 2 is connected with a vacuum extractor 4 through a rotary joint 6. A plurality of air holes 8 communicated with an inner cavity 7 of the driving roller 2 are uniformly distributed on the outer wall of the driving roller to form an adsorption area 9. The projection of the contour of the adsorption zone 9 is rectangular. The edges of the width direction of the adsorption area 9 are two bus bars of the driving roller, the edges of the length direction of the adsorption area 9 are two arcs on the surface of the driving roller 2, and the distance between the arcs corresponds to the width of the material belt or is smaller than the width of the material belt. The radian of the arc is smaller than that of the arc formed on the driving roller by the gap between the pair of driven rollers 3 and the driving roller 2, namely, when the driving roller 2 rotates for one circle, the adsorption area 9 is completely separated from the material belt 10.
The working principle of the technical scheme is as follows: the material belt 10 passes through the gap between the driving roller 2 and the driven roller 3 and is attached to the outer wall of the driving roller 2. The driving roll 2 rotates under the driving of the driving device, and the inside of the driving roll 2 is in a negative pressure state under the action of the vacuumizing device 4. The adsorption area 9 on the driving roller 2 adsorbs the material belt 10 on the surface of the driving roller 2 and pulls the material belt 10 to advance, when the adsorption area rotates to the upper area between the pair of driven rollers 3, the adsorption area 9 is separated from the material belt 10, the circulation is carried out, and the driving roller 2 intermittently pulls the material belt 10. Continuous traction can be realized through reasonable design of the size of the adsorption area 9 and matching of the positions of the pair of driven rollers 3.
