Tensioning apparatus is made up of bearing, screw, stage clip, stop nut, the screw that matches with screw is arranged on the bearing, and bearing is fixed on the frame body of cylinder top, and screw passes the stub bore of regulating wheel roll shaft, be screwed on the screw of bearing behind the cover compression spring, its traversing through end is tightened with stop nut.
Tensioning apparatus also can be made up of carriage, fork-shaped rocking arm, rotating shaft, rotating shaft axle head handle, torsion spring, carriage is fixed on the frame body of cylinder top, rotating shaft is installed on the seat hole of carriage, the fork-shaped rocking arm is fastened in the rotating shaft, rotate with rotating shaft, there is torsion spring set fork-shaped rocking arm both sides in rotating shaft, make rocking arm keep maximum deployed position, and the axle of tensioning supporting-point roller places in the fork groove of fork-shaped rocking arm.
The stub bore that the two forks bottom of fork-shaped rocking arm has screw, screw to pass the regulating wheel roll shaft is screwed on the screw behind the cover compression spring, and its traversing through end is tightened with stop nut.
The periphery of tensioning supporting-point roller is drum shape, and it is good in neutrality that ring-shaped sand is had.
The two ends of tensioning supporting-point roller have ends inclined to one side end cap, ends inclined to one side end cap and also can make one with the tensioning supporting-point roller, prevents that endless abrasive belt from skidding off from the end limit.
Side at the fork-shaped rocking arm is equipped with anti-inclined to one side taper supporting-point roller, and when the tensioning supporting-point roller was in the operating position, anti-inclined to one side taper supporting-point roller touched mutually with endless abrasive belt just.
Fig. 1 is the most preferred embodiment structure chart that the utility model proposes;
Fig. 2 is Fig. 1 embodiment end-view;
Fig. 3 is a linearly tensioning apparatus schematic diagram of tensioning supporting-point roller;
Fig. 4 A, B are anti-inclined to one side taper supporting-point roller schematic diagrames;
Fig. 1 and Fig. 2 are most preferred embodiment structure chart and end-view.Carriage (14) is fixed on the frame body (1) of cylinder (6) top, rotating shaft (16) is installed on the seat hole (19) of carriage (14), should keep rotating shaft (16) parallel with cylinder (6) axle (6A), the available key of fork-shaped rocking arm (15), pin or screw are fastened in the rotating shaft (16), rotate with rotating shaft (16), the torsion spring (18) of fork-shaped rocking arm (15) both sides is enclosed within the rotating shaft (16), make fork-shaped rocking arm (15) keep maximum deployed position, tensioning endless abrasive belt (7), elastic force by torsion spring (18), the even tension that keeps endless abrasive belt (7), constant, even the abrasive band is subjected to still can keep constant after the thermal stretching because of friction; The stub bore (8B) that the two forks bottom of fork-shaped rocking arm (15) has screw (15A), screw (20) to pass tensioning supporting-point roller (8) axle (8A) behind the cover compression spring (21), is screwed on the screw (15A), and its traversing through end is pieced together tight with stop nut (13).Adjusting two screws (20) can keep the axle (8A) of tensioning supporting-point roller (8) parallel with the axle (6A) of cylinder (6); The axle head handle (17) of rotating shaft (16), overcome torsion spring (18) torsion, fork-shaped rocking arm (15) is rotated, reduce the wheelbase between tensioning supporting-point roller (8) and the cylinder (6), can endless abrasive belt (7) be enclosed within on tensioning supporting-point roller (8) and the cylinder (6) easily, after putting endless abrasive belt (7), decontrol handle (17), endless abrasive belt (7) promptly obtains uniform tension force.
Tensioning apparatus (9) also can adopt tensioning supporting-point roller (8) method of tensioning linearly as shown in Figure 3, unclamp stop nut (13) and adjust screw (11), can keep the axle (8A) of tensioning supporting-point roller (8) parallel with (6A) of cylinder (6), and, make endless abrasive belt have certain force of strain with the elastic force of stage clip (12).
Motor (5) rotates by blower fan and the cylinder (6) that belt wheel, driving-belt drive dust exhaust apparatus (4), for preventing endless abrasive belt (7) sideslip, the periphery of tensioning supporting-point roller is drum shape (22), analyze the stressed of endless abrasive belt (7), promptly endless abrasive belt (7) has an axial thrust load as can be known, makes endless abrasive belt (7) operation placed in the middle.The two ends of tensioning supporting-point roller (8) are equipped with and are ended inclined to one side end cap (23), maybe will end inclined to one side end cap (23) and make one with the tensioning supporting-point roller, and its physical dimension can prevent effectively that greater than the body diameter of tensioning supporting-point roller (8) endless abrasive belt (7) from skidding off the end.
Also can adopt the side at fork-shaped rocking arm (15) as shown in Figure 4 to load onto anti-inclined to one side taper supporting-point roller (24), tensioning supporting-point roller (8) is when being in the operating position, and anti-inclined to one side taper supporting-point roller (24) touches mutually with endless abrasive belt (7) just.
During the utility model work, manipulation device (3) is by being installed in the pull bar at hand push position, the front vehicle wheel (2) that is installed in frame body (1) bottom is packed up, the outer endless abrasive belt (7) of cylinder (6) is contacted with the floor carry out grinding, because the radius of curvature of tensioning supporting-point roller (8) and cylinder (6) does not wait, so endless abrasive belt (7) circulation time, constantly do the different curvature radius bending, wood chip is difficult for being embedded on endless abrasive belt (7) surface, keep the grinding in abrasive band sharp, improve grinding quality, prolong the abrasive band life-span.When not working, manipulation device (3) puts down front vehicle wheel (2), and cylinder (6) lifts thereupon, realizes idle running.
The utility model compared with prior art has the following advantages: owing to disposed the tensioning supporting-point roller And tensioning apparatus, the endless abrasive belt tensile force is even, constant, endless abrasive belt and cylinder stickiness Good, do not have relative slippage, and constantly with the different curvature radius bending, wood chip is difficult for being embedded in the abrasive band Grinding quality can be improved in the surface, prolongs the abrasive band life-span.
