Description
Technical field
The present invention relates to field of plastics manufacture, be specifically related to a kind of plastic film winding 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; plastic sheeting after calendaring molding needs rolling mechanism to carry out rolling; when to plastic sheeting rolling; owing to thin film can be the most sagging, and by the disturbance of natural wind, thin film usually there will be fold; in order to smooth after ensureing film take-up; it is thus desirable to manually flatten thin film at any time, whole process needs a large amount of artificial participation, inefficient operation.
Summary of the invention
It is an object of the invention to provide a kind of plastic film winding device that can automatically be flattened when rolling plastic sheeting.
For reaching above-mentioned purpose, the base case of the present invention is as follows:
Plastic film winding device includes support, outlet roller and driving motor, and the top of support is provided with roller, and mid-stent is provided with nip rolls, and described outlet roller is located at below nip rolls, is provided with idler roller between described nip rolls and outlet roller；Described upper roller, nip rolls and idler roller are all hinged on support, two sections, the left and right of described upper roller is provided with oppositely oriented one-level and flattens helical groove, two sections, the left and right of described nip rolls is provided with oppositely oriented two grade and flattens helical groove, one-level flattens helical groove and two grades of pitch flattening helical groove are gradually increased, and one-level flattens in helical groove and two grades flatten helical grooves and is inlaid with rubber strip, rubber strip surface exceeds upper roller and nip rolls surface 0.5～1.5mm；Being rotatably connected to bracket on described support, bracket is removably connected with fixed block, the two ends of described outlet roller are fastened between bracket and fixed block, and described driving motor is connected with bracket, upper roller and nip rolls.
The principle of this programme plastic film winding device is:
When needs rolling plastic sheeting, plastic sheeting first passes around roller, then passes around nip rolls and idler roller, and one end of plastic sheeting is fixed on outlet roller；Owing to driving motor that bracket, upper roller and nip rolls can be driven to rotate, and the two ends of outlet roller are fastened between bracket and fixed block, therefore drive motor that outlet roller can be driven to rotate；When outlet roller rotates, plastic sheeting will be wrapped on outlet roller, and upper roller and nip rolls rotate the purpose that then can reach feeding；Owing to rubber strip surface exceeds upper roller and nip rolls surface 0.5～1.5mm, therefore plastic sheeting will directly contact with rubber strip, make plastic sheeting bigger with the frictional force of upper roller and nip rolls, and owing to rubber strip is in spiral distribution on the surface of upper roller and nip rolls, therefore when upper roller and nip rolls rotate, rubber strip can produce the tensile force towards both sides to plastic sheeting, to reach to flatten the purpose of plastic sheeting.And the two ends of outlet roller are fastened between bracket and fixed block, be conducive to changing outlet roller, to improve rolling efficiency.
This programme produces and provides the benefit that:
It is owing to the surface of upper roller and nip rolls defines frictional force to plastic sheeting that upper roller and nip rolls rotation can realize the reason of feeding, owing to upper roller and nip rolls have relative trackslipping with plastic sheeting, and rubber strip spiral is arranged, therefore Plastic film surface can form the tension force towards both sides, thus plastic sheeting is flattened, to reduce artificial input；And rubber strip surface only exceeds upper roller and nip rolls surface 0.5～1.5mm, can avoid forming impression on a plastic film, increase the frictional force of rubber strip and plastic sheeting simultaneously；Owing to plastic sheeting is the closer to upper roller and the end of nip rolls, the frictional force being subject to is the least, is therefore easier to flattened, so one-level flattens helical groove and two grades of pitch flattening helical groove are gradually increased, can strengthen flattening effect.
Preferred version one: as the further optimization to base case, it is symmetrical along the symmetrical plane of upper roller that described one-level flattens helical groove, two grades of flattening helical grooves are symmetrical along the symmetrical plane of nip rolls；Frictional force on this optimization plastic sheeting keeps balance, prevents plastic sheeting towards skew.
Preferred version two: as the further optimization to base case, described one-level flattens the pitch of helical groove and flattens the pitch of helical groove more than two grades；This optimization mainly makes one-level flatten helical groove and two grades of flattening helical grooves form difference, so that the rubber strip of correspondence has different effects, the rubber strip that i.e. one-level flattening helical groove is corresponding has the effect of preliminary flattening, two grades flatten rubber strip corresponding to helical groove and then play the effect of correction, thus improve flattening effect.
Preferred version three: as the further optimization to base case, described nip rolls is positioned at immediately below roller, and described idler roller is positioned at above nip rolls and outlet roller；This optimization mainly increase plastic sheeting and upper roller and the contact area of nip rolls, thus increasing friction force, flatten effect to improve.
