Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, belt conveyer automatic deviation correction carrying roller group, it comprises frame 1 and is arranged at the belt 13 of frame 1 top, it also comprises base 2, vertical shaft 3, carrying roller 6 and deflection correction roller 8, the middle part of frame 1 is fixed with base 2, the lower end of vertical shaft 3 is arranged in base 2 by bearing pair, the upper end of vertical shaft 3 is fixed with the adapter plate 4 of level, the top of adapter plate 4 is provided with roller carrier shaft 5, carrying roller 6 is sleeved on the outside of roller carrier shaft 5, the two ends of carrying roller 6 are provided with side along 7, and the reverse-running section of belt 13 contacts with carrying roller 6, and the edge of belt 13 reverse-running sections is positioned at the inner side of side along 7; As shown in Figure 3, the two ends of adapter plate 4 are respectively arranged with support plate 14 along the direction of transfer of belt 13, the end of every support plate 14 is provided with deflection correction roller 8, two deflection correction roller 8 are positioned at the both sides, road of belt 13 reverse-running sections, under normal circumstances, between deflection correction roller 8 and belt 13 edges, leave an intersegmental gap, be convenient in the situation that belt 13 does not have sideslip, deflection correction roller 8 does not contact completely with belt 13, makes the wearing and tearing of belt 13 less.
As depicted in figs. 1 and 2, the downside at described adapter plate 4 two ends is also fixed with otic placode 9, the bottom of otic placode 9 is provided with the supporting-roller shaft 10 of level, support roller 11 is installed in supporting-roller shaft 10, in the frame 1 of support roller 11 belows, be also provided with support roller runway 12, do not have sideslip at the reverse-running section of belt 13, have an intersegmental gap between support roller 11 and support roller runway 12, this gap can be adjusted according to actual loading situation.In the time of the reverse-running section sideslip of belt 13, the reverse-running section of belt 13 moves to stressed larger carrying roller 6 one lateral deviations, adapter plate 4 is being subject to sinking in weight situation, support roller 11 contacts with support roller runway 12, for adapter plate 4 bearing certain pressure, prevent adapter plate 4 gravitates and bending or in rotary moving having some setbacks.
As shown in Figure 3, the cross-sectional plane of described adapter plate 4 is U-shaped structure, and adapter plate 4 makes for steel, and such structure can reduce the use amount of steel, can meet again its bending strength.
The reverse-running section of belt 13 is not in the situation that there is no sideslip, its edge does not all contact with deflection correction roller 8 along 7 with the side of carrying roller 6, in the time there is sideslip in the reverse-running section of belt 13, the reverse-running section of belt 13 moves to the stressed larger lateral deviation of carrying roller 6, until the reverse-running section of belt 13 contacts along 7 inwall with side, move ahead in process at the reverse-running section of belt 13, the rotation that carrying roller 6 equates with the reverse-running section retention wire speed of belt 13, side along 7 and the reverse-running section of belt 13 between produce friction of rolling, the friction force that the stressed larger side of carrying roller 6 is moved forward, carrying roller 6 rotates under this application force, side reduces along the distance at the 7 reverse-running section centers to belt 13, the reverse-running section of belt 13 is subject to from side along 7 thrusts, the reverse-running section of belt 13 moves to the opposite side of carrying roller 6 under thrust, but one of reason of the reverse-running section sideslip of belt 13 may be object unbalance loading, must cause adapter plate 4 to sink because object is overweight, now support roller 11 sinks, and touches on support roller runway 12, and adapter plate 4 can be rotated smoothly.
In actual use, may be subject to the restriction of installing space, rotating mechanism can not be installed, can not mounting seat 2 and vertical shaft 3, adapter plate 4 also can be fixed in frame 1, adapter plate 4 is rigidly connected with frame 1, roller carrier shaft 5 is fixed on adapter plate 4, and carrying roller 6 is arranged on roller carrier shaft 5, when the reverse-running section sideslip of belt 13, be subject to the thrust of side along 7, also can play rectifying effect.Deflection correction roller 8 and the detachable use of carrying roller 6, that is to say independent use deflection correction roller 8, and deflection correction roller 8 is arranged in frame 1, also can realize correction.
