A kind of foam forming machine of dermatine
Technical field
The invention belongs to dermatine technical field, more particularly to a kind of foam forming machine of dermatine.
Background technology
Dermatine is configured to one layer of fabric substantially, and the one layer of foaming layer coated on this layer of fabric.Wherein fabric
Can be one of cotton, fiber crops, nylon, polyester, polyethylene, polypropylene, acryl etc., and foaming layer is relatively conventional for poly- ammonia
Ester (PU) and polyvinyl chloride (PVC) etc..In the prior art, the foaming of foaming layer generally uses two kinds of approach:First, under normal pressure
Continuous foamed, the advantages of this technique, is to realize the continuity of production, and the length of the dermatine after foaming can be with
Keep the length of the master slice before foaming, but this approach is there is also disadvantage, the hole of the dermatine after foaming under normal pressure compared with
Greatly, surface irregularity also needs following process.Second, pressing mold foams, this approach is to heat mold by stitching surface, is made
The advantages of in-mold molding chamber interior foaming layer foaming, this technique, is that the dermatine hole after foaming is thin
Close, dermatine various physical properties are improved, but the disadvantage is that, cannot achieve continuous production, significantly reduce life
Efficiency is produced, and the size of the dermatine after foaming is restricted by mould inside molding room space.
Invention content
Foam process to solve the foaming layer of dermatine in the prior art cannot achieve continuous production or obtained
The disadvantage of dermatine physical property difference, the present invention provide a kind of foam forming machine of dermatine, not only ensure continuous production simultaneously
Also greatly improve the various physical properties of dermatine.

Technique effect:
The present invention provides a kind of foam forming machine of dermatine, including the first track conveying device, the second crawler belt are defeated
Device and heating device, the foaming layer that heating device is used to be heated to be the first crawler belt and the second crawler belt master slice is sent to provide hot ring
The upper outer surface of border, the outer lower face surface of the first crawler belt and the second crawler belt cooperates keeps it defeated from crawler belt for master slice to be clamped jointly
It send one end of device to be transported to the other end, to realize the continuity of production, while providing compression during transmission for master slice
Environment, therefore, master slice complete the process of continuous compression foaming during being transmitted.
The foaming process of master slice is completed on a conveyor, realizes the continuity of production process;The foaming of master slice
The foaming process of layer is completed under continuous compression state, and the bubble in foaming layer is a large amount of microbubble, is improved obtained
Dermatine physical property, that is, improve the quality of dermatine.
The foam forming machine further includes having regulating device, the outer lower face surface and the second crawler belt for adjusting the first crawler belt
Spacing between outer surface, that is, the pressure being applied in the upper and lower surface of master slice is adjusted, by changing residing for foaming layer
Pressure environment changes the physical property of dermatine.
The first heat-conducting layer and the second heat-conducting layer, heating device have been respectively coated by the outer surface of first crawler belt and the second crawler belt
The first heat-conducting layer and the second heat-conducting layer are heated respectively, the first heat-conducting layer and the second heat-conducting layer after being heated are the hair of master slice jointly
Alveolar layer provides thermal environment, to promote its foaming.First heat-conducting layer and the second heat-conducting layer can be arranged to self-contained unit and may also set up
Integral device, therefore the first heat-conducting layer and the second heat-conducting layer can need to set different temperature according to processing.
First track conveying device and the second track conveying device respectively include the first driving mechanism and the second driving mechanism,
First driving mechanism and the second driving mechanism are respectively used to the first crawler belt of driving and the second caterpillar drive, adjust the first crawler belt
With the speed of the second caterpillar drive, make the foaming process of the foaming layer of master slice by the first crawler belt while to ensure production efficiency
It is completed during being clamped with the second crawler belt.Due to for two driving mechanisms, the movement speed of the first crawler belt and the second crawler belt
Degree can do different adjustings as needed.
