Abstract
The invention discloses a plastic film winding device and relates to the field of plastic manufacture. The plastic film winding device comprises a support, a feed roller, spreading rollers, a discharge roller, and a driving motor that drives the feed roller and the discharge roller to rotate. The feed roller is located between and higher than the spreading rollers that are disposed at a right side of the support. The feed roller rotates faster than the discharge roller. A tensioning roller is disposed between and slightly higher than one spreading roller and the discharge roller. The tensioning roller comprises a roller body, a roller shaft, and end caps fixed to two ends of the roller shaft. The roller body defines an air chamber, and comprises a rubber layer and steel bars fixed thereto. A plurality of bar-shaped grooves are radially formed in each end cap. Ends of the steel bars are embedded in the corresponding bar-shaped grooves. An air hole communicating with the air chamber is formed in the roller shaft, and an air connector is disposed at an end of the roller shaft. The tensioning roller provided in the plastic film winding device has a flexible body, i.e., is capable of deforming under pressure produced by a film; thus, the tension of the film can be controlled within a reasonable range.
Description
Technical field
The present invention relates to field of plastics manufacture, be specifically related to a kind of plastic sheeting coiler device.
Background technology
Plastic sheeting is mainly made by with polrvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, is used for packing, and is used as coating layer.The commercially shared share of plastics package and plastic packet product is increasing, particularly composite plastic flexible package, have been widely used for the fields such as food, medicine, chemical industry, maximum with packaging for foodstuff proportion the most again, such as beverage packaging, quick frozen food packaging, cooking food packaging, fast food packaging etc., these products all bring great convenience to people's life.In the production process of plastic sheeting, the plastic sheeting after calendering formation needs rolling mechanism to carry out rolling, when to plastic sheeting rolling, in order to prevent thin film from fold occur, often needs thin film tensioning, to ensure that thin film is smooth；Existing wrap-up, is the most all by nip rolls and feeding roller stretched film, and wherein nip rolls is driven voller, and feeding roller is drive roll, feeding roller pulls thin film to move by frictional force, otherwise thin film is that nip rolls rotates by frictional force, realizes thin film tensioning with this；But owing to thin film ductility is good, the most easily stretching after stress, and stress excessive after be easily torn, therefore nip rolls and feeding roller surface can not be excessive with the frictional force of thin film, the most often occur that thin film can not the situation of tensioning, when making film, easily there is fold, or the situation that film rolling is fine and close not in thin film.
Additionally, due to when film, the diameter of film rolling can be gradually increased, and therefore the rolling speed of thin film can gradually accelerate so that the friction of the translational speed of thin film, thin film and each roller all can produce the tensile force of change, i.e. thin film and be difficult to control to.
Summary of the invention
It is an object of the invention to provide a kind of plastic sheeting coiler device, the tensile force of plastic sheeting, when film, can be controlled steady state by this plastic sheeting coiler device.
For reaching above-mentioned purpose, the base case of the present invention is as follows:
Plastic sheeting coiler device includes support, feeding roller, nip rolls and the outlet roller being rotatably connected on support, drives the driving motor that feeding roller and outlet roller rotate；Described driving motor is Chain conveyer with feeding roller and outlet roller, and described feeding roller is between nip rolls, and feeding roller is positioned at above nip rolls, and outlet roller is arranged on any side of the left and right sides of support；The rotating speed of described feeding roller, more than the rotating speed of outlet roller, is provided with the idler roller being rotatably connected on support, and idler roller is positioned at above nip rolls and outlet roller between described nip rolls and outlet roller；Described idler roller includes roll body, roll shaft and is fixed on the end cap at roll shaft two ends, described roll body surrounds air chamber, roll body includes plastic deformation stratification and steel bar, steel bar is uniformly fixed on plastic deformation stratification inner surface, two end cap opposite face be radially provided with some strip grooves, the end of steel bar embeds in corresponding strip groove, and roll shaft is communicated with the pore of air chamber, being provided with sealing ring between described steel bar and strip groove wall, roll shaft end is provided with gas joint.
The principle of this programme plastic sheeting coiler device and beneficial effect:
When needs film, first paper web should be nested with and be fixed on outlet roller, and thin film is sequentially passed through nip rolls, feeding roller, nip rolls and idler roller, then one end of thin film is fixed on paper web；When driving electric motor starting, outlet roller and feeding roller to rotate, feeding roller rotates and thin film will be made gradually to be wrapped on paper web, pulls thin film to move simultaneously；Arranging feeding roller is then to thin film be decomposed thin film everywhere by power, preventing Film Tear；And nip rolls is driven roll, feeding roller is that the frictional force that thin film is produced by drive roll, therefore nip rolls and feeding roller is contrary, the beneficially thin film between tensioning nip rolls and feeding roller.
And the tensioning of thin film between nip rolls and outlet roller, completed by idler roller, owing to the roll body of idler roller is propped up by idler roller by internal air pressure, therefore when thin film, the pressure of idler roller is increased, the diameter of idler roller roll body can shrink, the deflection of the thin film then walking around idler roller will reduce, and therefore the tensile force of thin film reduces；When the pressure of idler roller is reduced by thin film, and idler roller roll body will expand, then the deflection of the thin film walking around idler roller increases, then thin film tensile force becomes big；By the control to thin film tensile force, can ensure that thin film will not tear, make again film rolling the finest and close simultaneously.
By the control to idler roller air chamber internal gas pressure, then the flexible degree of idler roller roll body will change, i.e. deflection during idler roller roll body pressurized will change, and therefore control at desired value by the air pressure in idler roller air chamber, effectively can control the tensile force of plastic sheeting at steady state value.
Preferred version one: as the further optimization to base case, described sealing ring is set in steel bar end；Sealing ring main hermetic seal effect, prevents gas room pressure immediate loss, and sealing ring is arranged on steel bar end, is conducive to installing, and this kind of mounting means is conducive to steel bar to slide in strip groove,.
Preferred version two: as the further optimization to base case, described gas joint connects and has relief valve and control the Pressure gauge of air chamber pressure；Pressure-control valve and being provided with of relief valve beneficially regulate the pressure in air chamber.
Preferred version three: as the further optimization to base case, be equipped with rubber sleeve outside described nip rolls；Rubber sleeve is set and can suitably increase the frictional force on nip rolls surface and thin film, prevent nip rolls from producing relative to thin film and trackslip, and make tensile force unstable, make thin film produce fold.
