Description
Technical field
The present invention relates to mechanical field, and in particular to a kind of time processing PVC floor shaping mechanism.
Background technology
PVC stone plastic floors pass through the development of short 2 years, make hard floor development from single anti-marbling effect
To the various soft or hard floor of the various wall thickness of making, anti-timber floor, foamed light floor, environmental protection without methane plastic cement wood grain floor etc..
No matter the technique that any floor uses is substantially：The extruded machine of raw material and mould plasticizing slabbing, in the case of hot
Covering one layer by three rolling ray machine shapings while face needs the film of imitated marble or wooden grain, back side compacting rubberizing water to use
Pitted skin line (lines is in lower roll) be used as base material, it is secondary that substrate surface is carried out with the embossing machine with heating to press the recessed of antiskid decorative
Burr, finally painted to UV and hang coating line to surface progress Wear-resistant Treatment.
But prior art is especially lost time first using three PROCESS FOR TREATMENTs, process route elongates, and causes production week
Phase is oversize, influences the supply of material and sale of product.It is required artificial virtually more, cause product cost of labor it is paramount not under.
Embossing and extension are all heated when applying technique to base material, and this heating is only heated to the superficial layer of base material, first in secondary cooling
When can cause stress concentration, even if finished product is more smooth, still there is the hidden danger of deformation later.Production technology slightly adjust it is not in place just
Product deformation can be caused, the heater that can only be now painted by UV on extension coating line is heated at high temperature to it, makes whole ground
Plate softening is secondary again to place smooth rear cooling, causes energy consumption to increase.Multiple tracks technique productions require the factor increase of control, non-controllable
Factor increases, product occur embossing is deep mixed, embossing is not in place, hang apply UV paints are uneven behind, UV paints hang apply it is existing less than side etc.
As increasing, so as to cause control of product quality more difficult, substandard products are more, or even cause waste product.It is guarantee in per pass technique productions
Production line continuous and stable production must the large quantities of raw materials of stock and base material, especially base material to protect surface not scratch, surrounding
Zero defect, it is necessary to assure the base material of each pallet is spaced apart and can not pile up.This results in required hall space very
Greatly, the shortcomings of cost is higher is had enough to meet the need.
Publication No. CN105172155A patent, although can be with time processing PVC stone plastic floors, because of wear-resistant membrane and line
Manage film overlay film directly on anti-skidding felt wrapped roll, the anti-skidding felt wrapped roll with ridge design in overlay film gas can not emptying be trapped in
Between wear-resistant membrane and texture film, with there are many stomatas between two membranes during micro- sem observation, make product quality not high, and wear-resistant membrane
During with texture film overlay film to product, the draw ratio of film is more serious, causes lines to deform, while reduces yield rate.Secondly, every time
When changing wear-resistant membrane or texture film, the waste product that can all have 3-5 rice occurs.
The content of the invention
It is an object of the invention to provide a kind of time processing PVC floor shaping mechanism, in the anti-sliding pressure with ridge design
Before smooth roll effect, wear-resistant membrane and texture film is molded with base material overlay film, avoid gas can not emptying be trapped in wearing layer and line
Manage the phenomenon between film.
To achieve the above object, the technical solution adopted in the present invention is：According to Product processing order, including head and the tail order
Batch mixer, extruder, feeder, mould, overlay film calender, hauling machine and the plate shearing machine of connection, overlay film calender and hauling machine

On film passed through between two rubber rolls 541 in this group of rubber roll component 54, gripper cylinder 542 connects with one of rubber roll 541
Connect, gripper cylinder 542 can drive the rubber roll 541 closer or far from another rubber roll 541 two rubber rolls 541 to be pressed from both sides
Hold or discharge the film.Deflector roll 543 provides the direction of walking to the film, i.e., passes through the side of deflector roll 543 when film is run.Change film
Rubber roll 541 in one group of rubber roll component 54 of the top of cylinder 55 and rolling assemblies 51 is connected, change film cylinder 55 can drive it is described
Rubber roll 541 moves towards the rubber roll 541 in another group of rubber roll component 54, two groups of rubber roll components 54 close to when, on two air-expanding shafts 511
Film can be pasted together by double faced adhesive tape head and the tail, such two groups of rubber roll components 54 alternation reduces the waste of film, and saves
Province reloads the time.
In the present embodiment, there are two smooth roll components 52, each smooth roll component 52 includes smooth roll 1, smooth roll two
522nd, elevating mechanism 523 and actuating unit 524, smooth roll 1 are located at the top of smooth roll 2 522, wear-resistant membrane, texture film and base material
Gap through smooth roll 1 and smooth roll 2 522, elevating mechanism 523 are connected with smooth roll 1 to control smooth roll 1
The size in gap between smooth roll 2 522, actuating unit 524 are connected dynamic to provide operating to smooth roll 2 522 with smooth roll 2 522
Power.
Nip rolls 513 enters overlay film calender 5, thermal insulation board 56 close to smooth roll component 52, base material from the side of nip rolls 513
It is radiated between nip rolls 513 and the base material with blocking the heat on the base material on wear-resistant membrane or texture film, so as to
Protect wear-resistant membrane or texture film.Smooth roll component 52 is electrically connected with a temperature control system to detect and adjust temperature.
After base material is via overlay film calender, its surface can be covered with wear-resistant membrane and texture film, and moreover, the surface of base material is also
Concavo-convex anti-slip veins can be suppressed by anti-skidding felt wrapped roll 53.
The operation principle of the overlay film calender 5 of the present invention is as follows：It is wound with an air-expanding shaft 511 of wear-resistant membrane or texture film
On wear-resistant membrane or texture film pass through a rubber roll component 54, wear-resistant membrane or texture film pass sequentially through deflector roll 543, guide roller 512,
Nip rolls 513 is run to smooth roll component 52, is unified in the opening position wear-resistant membrane of smooth roll component 52, texture film and base material three, overlay film
After the completion of base material finally by anti-skidding felt wrapped roll 53 compacting asperities.
The time processing PVC floor shaping mechanism process of the present invention is as follows：The different material on floor is prepared first mixed
Mixed in material machine 1, the extruded heating plasticizing of machine 2, then enter overlay film through the flexible sheet under the extrusion plasticizing state of mould 4, flexible sheet
Calender 5 covers wear-resistant membrane and texture film, and then carrying out side to the base material of shaping through trimming cutting device 9 cuts, in leading for hauling machine 6
The gravitation clipped machine 7 that flows down require the cutting of specification, has been eventually fabricated PVC stone plastic floor finished products, has stacked and preserve.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
It is corresponding to change and deformation, and all these change and deformation should all belong to application claims protection domain it
It is interior.
