Description
Technical field
The present invention relates to a kind of belt pulley and regulate device.
Background technology
Conveyer belt, also known as conveyer belt, is for playing carrying in belt conveyor and transporting rubber and fiber, the metal composite goods of material effect, or the goods of plastics and fabric compound. Conveyer belt, belt conveyor is widely used in the various solid blocks of conveying and powder shape material or work piece in agricultural, industrial and mining establishment and transportation, conveyer belt energy serialization, high efficiency, high-inclination conveying, conveyer belt operation safety, conveyer belt is easy to use, and maintenance is easily, freight charges are cheap, and transportation range can be shortened, reduce construction costs, use manpower and material resources sparingly.
Conveyer belt of the prior art, including belt pulley and belt, belt pulley includes driven pulley and drivewheel, needing first to be arranged in frame by driven pulley and drivewheel, belt it is generally required to longer than the distance of driven pulley left end to drivewheel right-hand member, so could be successfully arranged on driven pulley and drivewheel by the length of belt, but the rate of tension of belt is relatively low, therefore, after installation, belt all can become slack and undisciplined, less stable; Conveyer belt, when carrying object, also easily makes object jolt, even falls.
Summary of the invention
The invention is intended to provide a kind of rate of tension belt pulley improving belt to regulate device.
Belt pulley in this programme regulates device, including frame, driven pulley and drivewheel, drivewheel is rotatably connected in frame, described frame slidably connects the first bearing, driven pulley is rotatably connected on the first bearing, first bearing is connected to tooth bar away from the side of drivewheel, tooth bar is engaged with gear, frame between first bearing and drivewheel slidably connects slide bar, it is connected to elastic component between slide bar and the first bearing, being connected to screw rod on slide bar, screw flight is connected in frame, and screw rod has nut away from the side of slide bar is threaded.
The know-why of this programme and have the beneficial effect that frame can be used to fixing whole belt pulley and regulates device, plays the effect supporting whole device, makes whole belt pulley adjustment device stably to run.
When changing or install belt, first rotating gear, gear driven tooth bar moves, and tooth bar will promote driven pulley to move near the direction of drivewheel, and the distance between drivewheel and driven pulley shortens; Simultaneously because slide bar is bolted in frame, slide bar will not move, and elastic component will be compressed.
Then belt is put on driven pulley and drivewheel, swing pinion, gear driven tooth bar moves, rack drives driven pulley is moved to the direction away from drivewheel, distance between drivewheel and driven pulley is elongated, and belt will be strained by drivewheel and driven pulley, thus improve belt tightening, improve the stability of conveyer belt, elastic component stretches;Then rotating nut, screw rod moves wanting near the direction of nut, screw rod moves to close or away from driven pulley direction with moving slide-bar, and elastic component will be compressed or stretch, and the rate of tension of elastic component improves, and by the first bearing tension or compression, thus improve the stability of the first bearing, further increase the stability of conveyer belt, and when carrying object, conveyer belt will be less susceptible to make object jolt, and object is also less susceptible to fall from conveyer belt.
Further, elastic component is spring. Spring structure is simple, easy for installation, it is easy to control its rate of tension so that the stability of the first bearing is easily controllable.
Further, gear is connected to motor. Starting motor, gear rotates, and facilitates the control to gear.
Further, slide bar is provided with limited block away from the frame of the side of drivewheel, and limited block is provided with rubber blanket near the side of slide bar. The setting of fiber block, can make slide bar move distance limited, it is therefore prevented that the distance that slide bar motion is excessive, makes spring-compressed or stretches excessive and lost efficacy; Rubber blanket can avoid limited block directly to contact with slide bar, it is therefore prevented that limited block collides mutually with slide bar or phase mutual friction and loss, extends the use time of limited block and slide bar.
Further, frame being bolted the second bearing, drivewheel is rotatably connected on the second bearing. Bolt is easily installed and dismantles, and facilitates installation and the replacing of the second bearing.
Accompanying drawing explanation
Fig. 1 is the structural representation of inventive belt rotation regulating device embodiment.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Accompanying drawing labelling in Figure of description includes: frame 1, tooth bar 2, gear 3, screw rod 4, driven pulley 5, spring 6, slide bar 7, nut 8, bolt 9, drivewheel 10, limited block 11, rubber blanket 12.
Embodiment is basic with reference to shown in Fig. 1: belt pulley regulates device, including frame 1, driven pulley 5 and drivewheel 10, drivewheel 10 is connected to the first motor, frame 1 slidably connects the first bearing, driven pulley 5 is rotatably connected on the first bearing, frame 1 is connected to the second bearing by bolt 9, drivewheel 10 is rotatably connected on the second bearing, tooth bar 2 it is connected on the left of first bearing, tooth bar 2 is engaged with gear 3, gear 3 is connected to the second motor, frame 1 between first bearing and drivewheel 10 slidably connects slide bar 7, it is welded with spring 6 between slide bar 7 and the first bearing, slide bar 7 is connected to screw rod 4, screw rod 4 is threaded in frame 1, threaded on the left of screw rod 4 have nut 8, welded limiting block 11 in frame 1 on the left of slide bar 7, rubber blanket 12 it is bonded with on the right side of limited block 11.
When changing or install belt, first starting the second motor, rotate gear 3, gear 3 band carry-over bar 2 moves, and promotion driven pulley 5 is moved right by tooth bar 2, and the distance between drivewheel 10 and driven pulley 5 shortens; Being fixed in frame 1 simultaneously because slide bar 7 is bolted 9, slide bar 7 will not move, and spring 6 will be compressed.
Then belt is put on driven pulley 5 and drivewheel 10, continue swing pinion 3, gear 3 band carry-over bar 2 moves, tooth bar 2 is made to drive driven pulley 5 to left movement, distance between drivewheel 10 and driven pulley 5 is elongated, and belt will be strained by drivewheel 10 and driven pulley 5, thus improve belt tightening, improve the stability of conveyer belt, spring 6 stretches; Then rotating nut 8, screw rod 4 will to left movement, screw rod 4 band moving slide-bar 7 is to left movement, and moving to the position of limited block 11 always, slide bar 7 and rubber blanket 12 offset, and spring 6 will be compressed simultaneously, and the rate of tension of spring 6 improves, and the first bearing is compressed, thus improve the stability of the first bearing, further increase the stability of conveyer belt.
Starting the first motor, the first driven by motor drivewheel 10 rotates, and drivewheel 10 is rotated by belt drive driven pulley 5, and belt will stably operate.
