Abstract
The invention relates to an automatic correction device for a conveying belt, in particular to an automatic correction device of a conveying belt of a belt conveyor. The device is to solve the problems of serious belt wear or tear caused by belt deviation and waste caused by the scatter of conveyed materials from one side of the belt. For solving technical problems, the device adopts a technical scheme comprising: detecting the deviation situation of the belt (12) through detection switches (13 and 14); and then controlling the turning of a single-phase reversing motor (8) and pushing a screw (5) through a worm and gear reducer (7) to make a center line of a roller (11) vertical to that of the belt. The device has the advantage of automatically correcting the deviation of the belt when the belt conveyor works so as to prolong the service life of the belt and reduce the waste of the materials.
Description
Technical field
The present invention relates to a kind of automatic correction device for conveying belt, particularly relate to a kind of automatic correction device for conveying belt of band conveyor.
Background technology
At present, the used band conveyor of every profession and trade all adopts common leading screw to adjust the deviation phenomenon of belt, needs repetition test during adjustment, just is fixed on this position after adjusting.Yet cause the factor of belt deviation a lot, the quality problems etc. of inconsistent, belt of inhomogeneous, belt degree of wear of cloth above the belt itself all can make belt deviation like when transportation.Owing to as in time not finding, tend to make belt and frame direct friction to cause the belt severe wear or tear when belt can not automatic deviation correction sideslip occurs, scrap up to belt.And, the material that is transmitted is scattered away from a side causes waste.
Summary of the invention
For life-span of improving belt, cut the waste, the invention provides a kind of can be according to belt deviation situation self-align automatic correction device for conveying belt.
The present invention is made up of detector switch, single-phase electrical motor capable of reversing, worm-gear speed reducer, track adjusting wheel, orienting lug; It is characterized in that: two detector switches are connected on single-phase motor commutation electric capacity capable of reversing both sides respectively; Single-phase electrical motor capable of reversing and worm-gear speed reducer are fixed on the tension weight case of belt after connecting; Screw in the worm gear and leading screw spiral connect; Leading screw connects through coupling sleeve, brace rod and slide block, and slide block is positioned at the groove of belt feeder support channel-section steel.
The technical solution adopted for the present invention to solve the technical problems is: through the sideslip situation of detector switch detection belt, control turning to through worm-gear speed reducer promotion leading screw of single-phase electrical motor capable of reversing then and make the line of centers of cylinder vertical with the line of centers of belt conveyor.
The invention has the beneficial effects as follows, during band conveyor work belt is carried out automatic deviation correction, improve the service life of belt, reduce the waste of material.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further.
Structural representation when Fig. 1 is an idler roller of the present invention.
Fig. 2 is schematic circuit diagram of the present invention.
1 belt feeder support channel-section steel among the figure, 2 slide blocks, 3 brace rods, 4 coupling sleeves; Cover in 5 leading screws, the 6 worm gear screws, 7 worm-gear speed reducers, 8 single phase motors capable of reversing, 9 tension weight casees; 10 track adjusting wheels, 11 cylinders, 12 belts, 13 left detector switches; 14 right detector switches, 15 zero lines, 16 phase lines, 17 switching-over electric capacity, 18 machine winding one, 19 machine winding two.
The specific embodiment
As can beappreciated from fig. 1; The slide block 2 that is positioned at band conveyor support channel-section steel 1 groove is attached on the leading screw 5 through brace rod 3, coupling sleeve 4; Leading screw 5 connects with the interior cover of worm gear screw 6 spirals; Worm-gear speed reducer 7 all is bound up on the tension weight case 9 with single phase motor 8 capable of reversing, and left detector switch 13, right detector switch 14 are positioned at belt 12 both sides of the edge.
The principle of Fig. 2 is, when power supply through phase line 16, left detector switch 13, machine winding 1 during to zero line 15 also through switching-over electric capacity 17 shift to the back through machine winding 2 19 to zero line 15, motor is just changeed.When power supply through phase line 16, right detector switch 14, machine winding 2 19 during to zero line 15 also through switching-over electric capacity 17 shift to the back through machine winding 1 to zero line 15, make the motor counter-rotating.
Below in conjunction with accompanying drawing the principle of work that the present invention is used for belt stretcher is further specified:
Because of single phase motor 8 capable of reversing is through being parallel on the belt feeder cylinder 11 behind left detector switch 13, the right detector switch 14; When belt feeder is worked; If belt 12 sideslips make left detector switch 13 closures, single phase motor 8 then capable of reversing is just changeing, and the relative motion through worm-gear speed reducer 7 and silk red 5 makes tension weight case 9 adjust to anticlockwise direction; Do not contact with left detector switch 13 and left detector switch 13 is opened up to belt 12, switching-over single phase motor 8 stops operating; If belt 12 sideslips make right detector switch 14 closures; Single phase motor 8 counter-rotatings then capable of reversing; Relative motion through worm-gear speed reducer 7 and silk red 5 makes tension weight case 9 adjust to clockwise direction; Do not contact with right detector switch 14 and right detector switch 14 is opened up to belt 12, switching-over single phase motor 8 stops operating.Because of whole process is dynamically adjustment, carry out automatically.
The present invention also can be used for the belt automatic deviation correcting of frame head and tail.Just this device is linked on the frame and leading screw connects on the bearing seat with cylinder one side, and this bearing seat slides on frame, and the bearing seat of opposite side is for fixing, and two ends all adopt tilting bearing to get final product.
