Description

Polybag unwinding device
Technical field
The present invention relates to the production equipment technical field of polybag, and in particular to a kind of polybag unwinding device.
Background technology
Polybag is essential article in people's daily life, is often used to contain other articles.Because it is cheap, weight Extremely light, capacity is big for amount, be easy to the advantage of storage to be widely used.Polybag is in process of production, it is necessary to the lists of volume two that will be made Tunic is unreeled, and its rewinding is unreeled into duplicature, then by duplicature with other disk roller, and is cut to cutting mechanism small Section plastic foil, then carry out hot pressing etc. and be processed into polybag.
Need repeatedly to unreel plastic foil in the process of polybag, existing unwinding equipment is typically let off roll It is placed on the roller being rotatably connected in frame, further according to the length of let off roll, by manually inserting gear respectively in the both sides of let off roll Roller is stabilized it, then it is carried out to unreel operation with limiting the position of let off roll.Because the plastic foil in factory unreels workload Larger, manually slotting roller not only easily makes operator produce fatigue, and when roller is manually inserted, the hand of people is easily by folder machine Firmly, cause operator injured, be unfavorable for production.
The content of the invention
The invention is intended to provide polybag unwinding device, to be inserted roller automatically when polybag is unreeled.
To reach above-mentioned purpose, basic technology scheme of the invention is as follows：Polybag unwinding device, including feed hopper, enter Hopper includes integrally formed trough and feedboard, and trough is provided with through hole, and feedboard is oblique, and feedboard is away from blowing One end of groove is high-end, and feedboard is vertically slidable with the connecting portion of trough to be connected with briquetting, is provided with dynamic below feed hopper Power room, is provided with block roller telescoping mechanism and the vertical block roller installed in power house, block roller is located at the lower section of through hole, block roller telescoping mechanism Short tooth bar including being fixedly connected on briquetting lower end, is engaged with external gear on the outside of short tooth bar, external gear outside is provided with planet tooth Wheel mechanism, planetary gears includes gear ring and planet carrier, and the outside of gear ring is provided with several teeth, and the center of gear ring is provided with tubular Sun gear, gear ring is engaged with external gear, and gear ring inner is provided with the planetary gear being rotatably connected on planet carrier, and planetary gear is located at the sun Between wheel and gear ring, planetary gear is engaged with sun gear and gear ring simultaneously, and sun gear outside is vertically provided with what is engaged with sun gear Tooth bar long, tooth bar long is slidably connected on the side wall of power house, and the lower end of tooth bar long is fixedly connected with active piston, active piston Outside be provided with gap cooperation tracheae, tracheae away from one end of active piston be provided with gap cooperation relay piston, driven work The one end filled in away from tracheae is fixedly connected with block roller.
The principle and advantage of this programme be：During practical application, the block roller for using is lightweight block roller.Emptying roller by it is inclined enter Flitch is rolled into trough, so as to extrude the briquetting at feedboard and trough link position, moves down briquetting, and promotes short tooth Bar is moved down.The external gear engaged with short tooth bar rotates under the slip of tooth bar, and drives the ring gear against rotation for engaging, gear ring The planetary gear rotation that will be promoted again and engage is rotated, planetary gear starts rotation, while around sun gear rotation.Planetary gear is in rotation During turning, sun gear will be promoted to follow its common rotation.The rotation of sun gear, drives the tooth bar long movement for engaging again. In the process, the displacement for occurring because briquetting is pressed by emptying roller is smaller so that the displacement of short tooth bar is smaller, short tooth Bar promotes the angle of external gear rotation small, and external gear promotes the angle of ring gear against rotation also smaller, but is driven by gear ring in power When to planetary gears, planetary gear will promote sun gear high-speed rotation, because the number of teeth and the diameter of sun gear are much larger than row Star-wheel, so that sun gear promotes the big several times of displacement that the displacement that tooth bar long occurs can occur than short tooth bar, tooth bar long is promoted Active piston is slided in tracheae, the air in compression gas pipe, and air promotes relay piston sliding in tracheae under squeezing action It is dynamic, so that the block roller of the lightweight on relay piston is ejected into trough by relay piston by through hole, because displacement is through row Star gear mechanism is able to be exaggerated several times, and now, block roller is possible to be pushed in trough completely by relay piston, is achieved in Automatic clamping of the block roller to emptying roller two ends, improve production efficiency.The present invention makes block roller certainly by emptying roller to pressing for briquetting The dynamic two ends for being inserted in emptying roller, can realize the automatically slotting roller of device, meanwhile, using planetary gears by the displacement of briquetting Expand several times, block roller is fully inserted into trough, so as to effectively be clamped to emptying roller, effectively prevent blowing Roller swings during unreeling.
Preferably, improved as one kind, planetary gear is provided with three, and three planetary gears are set in isosceles triangle.Planetary gear During driving sun gear to rotate, influenceed by engagement motive force, the easy discontinuity equalization of sun gear and cause transmission uneven Surely.Three planetary gear common rotations in isosceles triangle distribution are set, make sun gear stress steady, thus beneficial to planetary gear with Active force between sun gear steadily and is effectively transmitted.
Preferably, improved as one kind, rubber layer is equipped with the tooth of external gear, gear ring, planetary gear and sun gear.Each portion When engaging, rubber layer can reduce the noise produced during engagement to part, to reduce noise pollution.
Preferably, improved as one kind, be hinged between the side wall and bottom wall of trough.After emptying roller completes to unreel, rotation Turn to open the side wall of trough, then push new emptying roller and enter trough, the emptying roller of entrance will promote completion to unreel work Emptying roller depart from trough, so as to realize the automatic discharge of trough.
Preferably, improved as one kind, the side wall of power house is provided with vertical guided way, and block roller is slidably connected at guiding In rail.In this way, block roller is in moving process, by the slide straight under the guide effect of guided way, so as to ensure that block roller can be by Through hole is accurately slided out in trough, prevents block roller from being shifted in motion process, and cannot be inserted into trough.
Preferably, improved as one kind, air-cooler is provided with inside power house, air-cooler is connected with motor.Under motor effect, Air-cooler is blown a cold wind over to power house and is lowered the temperature, to prevent machine components from damaging zero because friction produces high temperature in motion process Part performance.
