Description

Film take-up with pressure regulating mechanism

Technical field

The utility model belongs to plastic products rolling equipment technical field, has pressure regulating mechanism more particularly to one kind Film take-up.

Background technique

During PVC calendered film produces, wherein last procedure is the coiling process of PVC film, therefore batches Process inherently plays the important function for guaranteeing film article quality.In the prior art, in PVC film coiling process, in gas Although swelling shaft two sides are provided with the runing rest of fixed air-expanding shaft, its force value acted on is fixed, and can not be adjusted, be caused to revolve Turn bracket and identical pressure value has been acted on for different PVC film products.It is thin but in the actual production process of PVC film There are the differences of soft or hard thin and thick for film, for soft, thick product, the required rotation in curly course of the thin article film of hard Turn that the pressure value of bracket is then bigger, is just avoided that occur gas trace, fold and the uneven flaw of section in product wrapup procedure in this way. So rationally adjusting work for different soft and hard, thin and thick in the curly course of film to improve the winding quality of PVC film Pressure value for air-expanding shaft.

Summary of the invention

The utility model be solve technical problem present in well-known technique and provide it is a kind of can be according to the soft or hard thin of product The actuating pressure of runing rest is respectively set in thickness, increase substantially film product quality and efficiency it is thin with pressure regulating mechanism Film wrap-up.

The utility model is adopted the technical scheme that solve technical problem present in well-known technique:

Film take-up with pressure regulating mechanism, including be mounted on contact roll shaft with coiling machine, contact roller, Runing rest, pinch roller and the air-expanding shaft above contact roller, it is characterised in that: between the contact roll shaft two sides and contact roller Runing rest is installed, the runing rest lower end drives cylinder equipped with runing rest, and the runing rest driving cylinder is mounted on It batches on base, has rotatable swivel plate, the swivel plate upper end installation by swivel plate axis connection in runing rest upper end There is pinch roller, the swivel plate lower end drives cylinder equipped with swivel plate, and the swivel plate driving cylinder is connected with by gas path pipe First reversal valve, pressure regulator valve and pressure gauge, the runing rest driving cylinder connect the second reversal valve by gas path pipe.

The utility model can also adopt the following technical scheme that

First reversal valve, pressure regulator valve and the second reversal valve are separately mounted in the pneumatic control case with coiling machine.

The utility model has the advantages and positive effects of: by adopting the above technical scheme due to the utility model, that is, existing It batches fuselage and the pressure-regulating device for acting on runing rest and pinch roller is installed, runing rest and pinch roller are made in coiling process The power downward for air-expanding shaft both sides reduces film shake up and down in coiling process, avoids film both sides fold and film It is uneven to roll up section；The actuating pressure of runing rest can also be respectively set according to the soft or hard thin and thick of product by pressure-regulating device, Keep the adjusting for being applied to the pressure that different PVC products batch more flexible.By the collective effect of above-mentioned two-part structure, in turn Improve the winding quality of film.The structure design of the utility model is reasonable, guarantees rolled products quality, high-efficient, low cost.

Specific embodiment

For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates Detailed description are as follows for attached drawing:

Fig. 1-Fig. 5 is please referred to, the film take-up with pressure regulating mechanism, including being mounted on connecing with coiling machine Touch roll shaft 5, contact roller 4, runing rest 6, pinch roller 8 and the air-expanding shaft 7 above contact roller.The contact roll shaft two sides with connect It touches and runing rest 6 is installed between roller, the runing rest lower end drives cylinder rotary shaft 12 that runing rest is housed by swivel plate Cylinder 13 is driven, the runing rest driving cylinder, which is mounted on, to be batched on base.Pass through rotation board shaft 10 in runing rest upper end It is connected with rotatable swivel plate 9, the swivel plate upper end is equipped with pinch roller 8.It is driven in the swivel plate lower end by swivel plate Cylinder rotary shaft 12 of taking offence drives cylinder 11 equipped with swivel plate, and the swivel plate driving cylinder is connected with first by gas path pipe 2 Reversal valve 1, pressure regulator valve 3 and pressure gauge, the swivel plate driving cylinder are equipped with independent pressure gauge, pressure limit 0-6kg； The runing rest driving cylinder connects the second reversal valve 1 by gas path pipe 2.

In the present embodiment, first reversal valve, pressure regulator valve and the second reversal valve are separately mounted to the gas with coiling machine In dynamic control cabinet.

In the present embodiment, the pressure preferred value that soft, the thick film product runing rest acts on air-expanding shaft is less than normal, and hard The pressure preferred value of runing rest needed for matter, thin membrane product is bigger than normal.

The working principle of the utility model are as follows:

PVC film is in coiling process, and last item and air-expanding shaft interact, and runing rest acts on the two sides of air-expanding shaft, It drives the effect adjusting runing rest of cylinder to act on the pressure value of air-expanding shaft two sides by swivel plate, air-expanding shaft is made to be in one kind Stable rolled state is conducive to film take-up appearance and quality.

The utility model in actual use, by coiling process runing rest act on air-expanding shaft both sides to Under power, reduce film in coiling process up and down shake, avoid film both sides fold and film roll section be uneven；Lead to simultaneously The actuating pressure of runing rest can be respectively set according to the soft or hard thin and thick of product, and then guarantee film more for excess pressure regulating mechanism Good winding.

Embodiment described in the utility model attached drawing is exemplary, and is only used for explaining the utility model, and cannot be managed Solution is limitations of the present invention.
