s1, rotating a gear shaft 51 to enable a rack 52 to axially move, and enabling the rack 52 to move to drive a corresponding driving gear 511 to move, so that the central axis of each driving saw wheel 20 is adjusted in the horizontal direction;
S2, rotating the eccentric adjusting screw 62 to enable the central axis of the driven saw wheel 30 and the central axis of the driving saw wheel 20 to be positioned on the same vertical plane, and then screwing the locking screw 63 on the positioning adjusting seat 6, and enabling the locking screw 63 to prop against the driven saw wheel shaft core 3;
S3, the tensioning shaft 41 is driven to extend through the hydraulic oil cylinder, so that the tensioning shaft 41 is propped against the driven saw wheel inner sleeve 31, and tensioning of the saw blade 4 is achieved.
Example two
Referring to fig. 12 to 16, unlike the embodiment, the multi-blade band saw of the present embodiment is a horizontal multi-blade band saw, and the movable device of the present embodiment is provided with only one group, and accordingly, the beam seat 11 is provided with only one, and the beam seat 11 is driven by the beam seat driving device to move in the vertical direction.
In the movable apparatus of the present embodiment, the central axis of the driving saw wheel 20 and the central axis of the driven saw wheel 30 are located on the same horizontal plane;
The width of the sleeve hole of the active saw wheel inner sleeve 21 in the vertical direction is larger than the width of the active saw wheel shaft core 2 in the vertical direction, and the width of the sleeve hole of the active saw wheel inner sleeve 21 in the horizontal direction is matched with the width of the active saw wheel shaft core 2 in the horizontal direction, so that the active saw wheel inner sleeve 21 can move on the active saw wheel shaft core 2 in the vertical direction;
The driving saw wheel shaft core through hole 53 vertically penetrates through the driving saw wheel shaft core 2, the gear shaft positioning seat 5 is vertically arranged in the concave cavity 54 side by side, the gear shaft 51 rotates to drive the gear 511 to rotate, the gear 511 and the tooth 521 are meshed to enable the rack 52 to axially move, and the rack 52 moves to drive the corresponding driving gear 511 to move, so that the central axis of the driving saw wheel 20 is adjusted in the vertical direction;
The width of the positioning adjusting seat 6 in the vertical direction is larger than that of the driven saw wheel shaft core 3 and is matched with the width of the sleeve hole of the driven saw wheel inner sleeve 31 in the vertical direction, so that the positioning adjusting seat 6 can move on the driven saw wheel shaft core 3 in the vertical direction, and the driven saw wheel inner sleeve 31 moves along with the positioning adjusting seat 6 in the vertical direction;
The screw hole 64 vertically penetrates through the driven saw wheel shaft core 3, and the eccentric adjusting screw 62 is rotated to drive the positioning adjusting seat 6 to move in the vertical direction, so that the central axis of the driven saw wheel 30 is adjusted in the vertical direction;
the extension and retraction direction of the tensioning shaft 41 is horizontal, and the extension direction of the tensioning shaft 41 is opposite to the direction toward the active saw wheel 20.
The steps for adjusting the saw blade spacing in this embodiment are as follows:
s1, rotating a gear shaft 51 to enable a rack 52 to axially move, and enabling the rack 52 to move to drive a corresponding driving gear 511 to move, so that the central axis of each driving saw wheel 20 is adjusted in the vertical direction;
S2, rotating the eccentric adjusting screw 62 to enable the central axis of the driven saw wheel 30 and the central axis of the driving saw wheel 20 to be in the same horizontal plane, and then rotating the locking screw 63 on the positioning adjusting seat 6 to enable the locking screw 63 to prop against the driven saw wheel shaft core 3;
S3, the tensioning shaft 41 is driven to extend through the hydraulic oil cylinder, so that the tensioning shaft 41 is propped against the driven saw wheel inner sleeve 31, and tensioning of the saw blade is achieved.
The rest of the structure is the same as in the first embodiment.
Example III
Referring to fig. 17, the multi-blade band saw of the present embodiment is a horizontal multi-blade band saw as well, and unlike the second embodiment, the present embodiment does not include a support, a beam seat sliding device, and a beam seat driving device, and the beam seat 11 is fixed on the frame, and the movable device does not move with the beam seat 11.
The rest of the structure is the same as the embodiment.
While embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents, and modifications and the like without departing from the spirit and scope of the invention.
