The utility model discloses in, the grinder is fixed in

frame

4, and 3 snap-fits of second support body are in frame 4, and the sand light roller is also exactly that live-rollers 1 fixes on first support body 2, and first support body 2 is again through erection column 23 installation to frame 4, then through the horizontal displacement and the upper and lower displacement of second support body 3 with the position relation control live-rollers 1 between the first support body 2 to accomplish the control around establishing the tensioning of the sand skin 11 on the live-rollers 1.

Firstly, the structure of the first frame body 2, the first frame body 2 comprises a shaft seat 21 connected with the rotating shaft 12 and a first column 22 arranged below the shaft seat 21, the shaft seat 21 is used for connecting the rotating roller 1, the rotating roller 1 is stabilized, and the vibration of the rotating roller 1 during working is reduced. The first column 22 is a vertically disposed column-shaped extension member, and extends toward the second frame body 3.

Then be the structure of second support body 3, second support body 3 including fixed setting in frame 4 on base 31 and through telescopic cylinder 32 with the second post 33 that base 31 is connected, second post 33 is the column extension piece of vertical setting, to the 2 direction extension settings of first support body. When the telescopic cylinder 32 is telescopic, the second column 33 is displaced towards or away from the first frame body 2.

Then, the relationship between the first frame body 2 and the second frame body 3 is described, the end of the first column 22 close to the second column 33 is provided with the first inclined surface 221, the end of the second column 33 close to the first column 22 is provided with the second inclined surface 331, and the first inclined surface 221 and the second inclined surface 331 are both magnetic-permeable members, after the first inclined surface 221 and the second inclined surface 331 are both magnetized, magnetic field force is generated between the first inclined surface 221 and the second inclined surface 331, when the telescopic cylinder 32 is telescopic, the second column 33 is displaced towards the direction close to or away from the first frame body 2, and the magnetic field force is changed, so that the first column 22 is driven to perform corresponding displacement on the first frame body 2.

Generally, the first inclined surface 221 and the second inclined surface 331 are magnetized in the same direction, and are radially magnetized. Thus, when the second post 33 moves upward, the first post 22 is repelled by the same polarity, and an upward magnetic force is generated.

Finally, the mounting post 23 controls the specific displacement direction of the first post 22 when the second post 33 is displaced, and the mounting post 23 includes a vertical post 231, a first cross post 232 for connecting the vertical post 231 and the shaft seat 21, and a second cross post 233 for connecting the vertical frame 231 and the first post 22.

first, the angle between the first inclined surface 221 and the first column 22 is not greater than the angle between the second inclined surface 331 and the second column 33.

Here, the angle between the first inclined surface 221 and the first column 22 is equal to the angle between the second inclined surface 331 and the second column 33, so that the second column 33 and the first column 22 are displaced synchronously.

Or, the included angle between the first inclined surface 221 and the first column 22 is smaller than the included angle between the second inclined surface 331 and the second column 33, and then when the second column 33 is displaced for a certain distance, the displacement distance of the first column 22 is small, so that the purposes of amplifying the control stroke and reducing the actual adjustment stroke are achieved, and thus the position adjustment of the rotating roller 1 is more precise and accurate, and fine adjustment is achieved.

Then, the angle formed between the second transverse column 233 and the first column 22 ranges from 80 ° to 100 °.

There are two optimized results here:

as a result, the angle formed between the second transverse column 233 and the first column 22 is 90 °, i.e. the second transverse column 233 is arranged perpendicular to the first column 22.

As a result, the angle formed between the second transverse column 233 and the first column 22 ranges from 95 ° to 100 °. A small obtuse angle is formed between the second transverse column 233 and the first column 22, so that when the first column 22 displaces along the extending direction of the second transverse column 233, the rotating roller 1 forms a small amount of vertical displacement, and fine adjustment is realized.

Finally, the number of the telescopic cylinders 32 is at least one, and the telescopic action of the second columns 33 is more stable.
