Abstract
The invention discloses a variable-speed driving device for a conveying belt. By the variable-speed driving device, the conveying belt can be driven at variable speeds. The variable-speed driving device comprises a rack, wherein a motor is arranged on the rack; a shaft of the motor is connected with a worm; the worm is meshed with a worm gear which is rotatably connected to the rack; the worm gear is fixedly connected with a radial guide rod; the guide rod is slidably connected with a slider in the axial direction; an output shaft which is rotatably connected to the rack is arranged beside the worm gear, is parallel to the axial direction of the worm gear and is fixedly connected with a belt pulley for outputting power outwards and a radial telescopic rod; and an end of the telescopic rod is hinged to the slider. By the variable-speed driving device, the conveying belt can work at different speeds, and different requirements in the existing environment can be met.
Description
Technical field
The present invention relates to a kind of load-transfer device speed-changing driving device.
Background technology
Feeder is exactly the machine of conveying material, is all indispensable equipment of light industry or heavy industry.Traditional concept, feeder is afterburning in material by means of the application force of feeder machine movement, carries out to material the machine transported that moves.The feeder in modern age there occurs some changes, start the pioneering technology such as high pressure air, super sonic to be used in feeding technology, but these equipment is still summarized in the equipment of feeding material machine class by people.
Load-transfer device, also known as conveyer belt, is the rubber for playing carrying and the effect of transport material in belt conveyor and fiber, metal composite goods, or the goods of plastics and fabric compound.Load-transfer device is widely used in the occasion that fed distance in food service industry is shorter, operational throughput is less.
In the course of conveying of food pack, sometimes need load-transfer device to carry out mass transport in the mode of speed change, common load-transfer device control setup cannot reach above-mentioned effect.
Summary of the invention
The invention is intended to provide a kind of load-transfer device speed-changing driving device, with variable speed drive (VSD) load-transfer device.
Load-transfer device speed-changing driving device in this programme, comprise frame, frame is provided with electrical motor, motor reel is connected with worm screw, worm screw engages with worm gear frame being rotated connection, worm gear is fixedly connected radial guide rod, guide rod slides axially and is connected with slide block, the output shaft be rotatably connected in frame is also provided with on worm gear side, output shaft is parallel with the axis of worm gear, output shaft is fixedly connected for the belt wheel of outside outputting power, output shaft is fixedly connected radial expansion link, and the end of expansion link is hinged on slide block.
This device using electrical motor as driving link, use worm drive worm gear and on guide rod rotate, the latching characteristics of worm and gear can ensure that load-transfer device can not reverse drive motor, causes motor damage.Namely the rotation of guide rod is rotated around output shaft by slider-actuated expansion link, because the position of slide block is changing at any time in this process, rotate so output shaft is also the speed change of carrying out rule, and expansion link is the rod member that its length can be made to be fixed on certain value, can by expansion link be adjusted to different length, load-transfer device can be realized and carry out work with different shifting characteristics, the different demands in existing environment can be met.
Further, electrical motor is change speed motor.Be convenient to change its power exported.
Further, expansion link is Multi-section telescopic rod.Length adjustment is convenient.
Further, expansion link comprises cylinder body and piston rod, and cylinder body is fixed on output shaft, and end and the slide block of piston rod are hinged.Can adjust the length of expansion link in the process of work, work adjustment is more flexible.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: electrical motor 1, worm screw 2, worm gear 3, guide rod 4, slide block 5, piston rod 6, cylinder body 7, output shaft 8, belt wheel 9.
Embodiment is substantially as shown in Figure 1: the electrical motor having variable-ratio to export frame being installed horizontal direction, motor reel stretches out to the left, and on it, binding is connected to coaxial worm screw, and worm screw engages with worm gear frame being rotated connection, using electrical motor as driving link, use worm drive worm gear wheel.The latching characteristics of worm and gear can ensure that load-transfer device can not reverse drive motor, causes motor damage.
Worm gear is fixedly welded with radial guide rod, guide rod can carry out the rotation of 360 ° and by the interference of other mechanisms, guide rod can not slide axially and be connected with slide block.
Also be provided with on worm gear side the output shaft be rotatably connected in frame, on output shaft, binding is connected to belt wheel, and output shaft is parallel with the axis of worm gear in the horizontal direction.Output shaft is fixedly connected radial expansion link, and expansion link comprises cylinder body and piston rod, and the tail end of cylinder body is fixed on output shaft, the piston rod end that cylinder body stretches out and slide block hinged.
Namely the rotation of guide rod is rotated around output shaft by slider-actuated expansion link, because the position of slide block is changing at any time in this process, rotate so output shaft is also the speed change of carrying out rule, and expansion link is the rod member that its length can be made to be fixed on certain value, by expansion link is adjusted to different length, can realizes load-transfer device and carry out work with different shifting characteristics.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in specification sheets etc. record the content that may be used for explaining claim.
