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, ribbon conveyer automatic deviation correction idler machining, it includes frame 1 and is arranged at the belt 13 above frame 1, it also includes base 2, vertical shaft 3, carrying roller 6 and deflection correction roller 8, frame 1 be fixedly arranged in the middle of 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 installing plate 4 of level, installing plate 4 be arranged above 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 section is positioned at the inner side that side is along 7; As shown in Figure 3, the two ends of installing plate 4 are respectively arranged with support plate 14 along the direction of transfer of belt 13, the end of every piece of 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 section, under normal circumstances, an intersegmental gap is left between deflection correction roller 8 and belt 13 edge, it is simple to when belt 13 does not have sideslip, deflection correction roller 8 does not contact completely with belt 13 so that the abrasion of belt 13 is less.
As depicted in figs. 1 and 2, the downside at described installing plate 4 two ends is further fixed on otic placode 9, the bottom of otic placode 9 is provided with the supporting-roller shaft 10 of level, supporting-roller shaft 10 is provided with support roller 11, frame 1 below support roller 11 is additionally provided with support roller runway 12, when the reverse-running section of belt 13 does not have sideslip, having an intersegmental gap between support roller 11 and support roller runway 12, this gap can be adjusted according to actual loading situation.When the reverse-running section sideslip of belt 13, the reverse-running section of belt 13 offsets to carrying roller 6 side that stress is bigger, installing plate 4 sinks under being subject to weight situation, support roller 11 contacts with support roller runway 12, certain pressure is born, it is prevented that installing plate 4 is bent by action of gravity or in rotary moving has some setbacks for installing plate 4.
As it is shown on figure 3, the cross section of described installing plate 4 is U-shaped structure, and installing plate 4 is made for steel, and what such structure can reduce steel makes consumption, can meet again its bending strength.
The reverse-running section of belt 13 is not when having sideslip, its edge does not all contact along 7 and deflection correction roller 8 with the side of carrying roller 6, when there is sideslip in the reverse-running section of belt 13, the reverse-running section of belt 13 offsets to the bigger side of carrying roller 6 stress, until the reverse-running section of belt 13 and side are along the contact internal walls of 7, reverse-running section at belt 13 moves ahead in process, carrying roller 6 keeps, with the reverse-running section of belt 13, the rotation that linear velocity is equal, side is along producing rolling friction between 7 and the reverse-running section of belt 13, make the frictional force that the bigger side of carrying roller 6 stress is moved forward, carrying roller 6 rotates under this active force, side reduces along the distance at the 7 reverse-running section centers arriving 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 reverse-running section sideslip of belt 13 is probably object unbalance loading, necessarily causing that installing plate 4 sinks owing to object is overweight, now support roller 11 sinks, and touches on support roller runway 12 so that installing plate 4 can smooth rotation.
In actual use, it is likely to be subject to the restriction of installing space, rotating mechanism can not be installed, namely can not mounting seat 2 and vertical shaft 3, installing plate 4 could be secured in frame 1, installing plate 4 and frame 1 are rigidly connected, roller carrier shaft 5 is fixed on installing plate 4, and carrying roller 6 is arranged on roller carrier shaft 5, during the reverse-running section sideslip of belt 13, it is subject to the thrust that side is along 7, also can play rectifying effect. Deflection correction roller 8 and the detachable use of carrying roller 6, say, that be used alone deflection correction roller 8, be arranged in frame 1 by deflection correction roller 8, also can realize correction.
