Description
Technical Field
The utility model relates to a central point puts variable gyro wheel belongs to health supplies and equips the field.
Background
In health supplies production facility, on some positions, two sets of belt group centre gripping product material are carried forward about adopting, because there is obvious difference in different main part material thickness, need adjust the clearance of two sets of belts, and the tradition adopts two kinds of adjustment methods usually: the position of the belt set is adjusted up and down as a whole, or the position of a roller in the belt set is adjusted by adopting a sliding groove and an adjusting screw. Both are time and labor consuming in effect, and are also limited by the space available for operation.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a central point puts variable gyro wheel, simple and practical only needs the unilateral adjustment in the operation side moreover, can realize the effect of the whole change in gyro wheel position.
The utility model discloses an above-mentioned technical problem is solved to following technical means:
a roller with a variable central position comprises an eccentric shaft, rollers and bearings, wherein a roller group is formed by the eccentric shaft, the rollers and the bearings, the roller group penetrates through an operation side fixing plate and a transmission side fixing plate, a locking block is arranged on the operation side fixing plate, the operation side fixing plate and the locking block are fixed through screws, the locking block is provided with a hole for fixing the eccentric shaft and a screw counter bore, a fixing block is arranged on the transmission side fixing plate, the transmission side fixing plate and the fixing block are fixed through screws, the fixing block is provided with a hole for fixing the eccentric shaft and a screw counter bore, one side of the hole for fixing the eccentric shaft is provided with a completely through groove, one side of the groove is provided with a screw through hole, the other side of the groove is provided with a screw hole, two side shaft heads of the eccentric shaft are positioned by the locking block and the fixing block, the fitting position of the locking block and the eccentric shaft adopts a half-Harvard structure.
The diameter of the middle of the eccentric shaft is larger than the diameters of the two ends, the two ends of the eccentric shaft are in the same center, the centers of the two ends of the eccentric shaft and the center of the middle section of the eccentric shaft are provided with eccentric distances, and flat squares are machined at the end parts of the two ends of the eccentric shaft.
The eccentric shaft is held tightly by the locking adjusting screw, and when the locking adjusting screw is loosened, the eccentric shaft is loosened.
The utility model has the advantages that: simple and practical, and the effect of the whole change of the position of the roller can be realized only by adjusting the single side of the operation side.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, in this embodiment, a roller set is composed of an eccentric shaft 3, a roller 4 and a bearing 5, the roller set passes through an operation side fixing plate 2 and a transmission side fixing plate 6, a locking block 1 is installed on the operation side fixing plate 2, the operation side fixing plate 2 and the locking block 1 are fixed by screws, the locking block 1 is provided with a hole for fixing the eccentric shaft 3 and a screw counter bore, a fixing block 7 is installed on the transmission side fixing plate 6, the transmission side fixing plate 6 and the fixing block 7 are fixed by screws, the fixing block 7 is provided with a hole for fixing the eccentric shaft 3 and a screw counter bore, one side of the hole for fixing the eccentric shaft 3 is provided with a through groove, one side of the through groove is provided with a screw through hole, the other side is provided with a screw hole, two side spindle heads of the eccentric shaft, the idler wheel 4 is connected with the middle shaft section of the eccentric shaft 3 through a bearing 5, the hole shaft matching positions of the eccentric shaft 3, the operation side fixing plate 2, the transmission side fixing plate 6 and the fixing block 7 are in clearance fit, and the matching position of the locking block 1 and the eccentric shaft 3 adopts a half-Harvard structure.
The diameter of the middle of the eccentric shaft 3 is larger than the diameter of the two ends, the two ends are at the same center, the centers of the two ends and the center of the middle section are provided with eccentric distances, and flat squares are processed at the ends of the two ends.
The eccentric shaft 3 is tightly held by the locking adjusting screw 8, and when the locking adjusting screw 8 is loosened, the eccentric shaft 3 is loosened.
As shown in fig. 1-3, the middle diameter of the eccentric shaft 3 is slightly larger, the diameters of the two ends are slightly smaller, the two end shafts are the same center, the center of the two end shafts and the center of the middle section shaft have an eccentricity K, the end parts of the two end shafts are processed with flat squares, so that the spanner can be operated and rotated conveniently, the roller 4 is connected with the middle shaft section of the eccentric shaft 3 through a bearing 5, and the matching positions of the eccentric shaft 3, the operation side fixing plate 2, the transmission side fixing plate 6 and the fixing block 7 are in clearance fit. The fitting position of the locking block 1 and the eccentric shaft 3 adopts a half-Harvard structure, and the eccentric shaft 3 is held tightly by the locking adjusting screw 8 and cannot rotate. When the locking adjusting screw 8 is loosened, the eccentric shaft 3 is loosened, and the flat square at the shaft head is clamped by a spanner, so that the eccentric shaft can rotate around the axis. Because the eccentric distance K exists between the shaft sections at the two sides of the eccentric shaft 3 and the middle shaft section, when the eccentric shaft 3 rotates 180 degrees, the central position of the roller 4 can be changed within the range of 0-2K.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
