Frame 200 is arranged on the opposite sides on base 100, and base 100 and frame 200 are welded by sheet material, its internal tool
There are multiple stiffener plates, to strengthen their intensity, frame 200 is bolted on base 100, the both ends of lower roll 400
It is arranged on respectively by a lower support of roller oil cylinder 410 in frame 200, two side rollers 500 are located at the both sides of lower roll 400 respectively,
The both ends of lower roll 400 are also supported by a side roller oil cylinder 520 be arranged in frame 200 respectively.
Traditional veneer reeling machine, upper roller 300 is also to be directly installed in frame, because working roll of veneer reeling machine pressure is very big, frame 200
High is required to the support strength of each roller, therefore, the frame of existing veneer reeling machine is all to use monolithic construction, corresponding reserving thereon
Hole, so as to each roller end load support.Although no doubt intensity is higher for the rack construction of monoblock type, the thing followed is again
There is disadvantage, i.e., each roller, hydraulic cylinder, and the part such as support needs to be installed in the mounting hole in frame accordingly, this is just
These parts are caused slowly to be filled in from the side of frame in corresponding mounting hole, and these parts are often larger heavier, it is necessary to row
Car etc. is installed again after slinging, and the plug-type mounting means in side is wasted time and energy, and is easily produced collision and caused danger, installation process
It is very careful with caution, often three or four people assemble together, also to spend the time of several days, seriously reduce production efficiency.And
And when rolling full circle pipe, in order to which pipe is removed, the one end of upper roller 300 is supported using fixed, and the other end uses turnover work
Dynamic support；Therefore, traditional two side stands are not symmetrical, but high low on one side on one side, and welding difficulty is higher, installation site precision
It is not easy to control.
