A kind of split type molding powder bonding device
Technical field
The present invention relates to a kind of molding powder manufacturing device, especially a kind of split type molding powder bonding device.
Background technique
Molding powder is the material of workmanship of spraying plastics, is in simple terms exactly that plastic powders pass through compressed air after high-temperature heating
The wind given is sprayed onto material surface.The effect of plastic-spraying is good, at low cost, and color is just, beautiful.Molding powder is a kind of electrostatic spraying thermosetting property
Powder includes the compositions such as coating solid resin, pigment, filler, auxiliary agent.Molding powder bonding be toner base-material is heated to it is slightly lower
In the temperature of resin softening point, the resin powder particles of pigment powder particle and softening is allowed to cohere, then cools down finished product.Such as
Molding powder bonding can be realized in a kind of molding powder bonding machines disclosed in Chinese Patent Application No. 201711266485.9.
Current molding powder bonding equipment has the following problems:
1, it is protruded into tank body using main shaft from lower part in current molding powder bonding machines, setting is rotated between main shaft and tank body, is made
With middle main shaft root(With the junction of tank body)It is easy fever, molding powder bonding is quite harsh to temperature control requirement, main shaft root
Material agglomerates during fever will lead to bonding, influences bonding quality.
2, agitating device is set in molding powder bonding shelf jar body, after the completion of bonding, is needed after replacing the material of different colours
The attachment molding powder in thorough cleaning tank and on rabbling mechanism is wanted, current main shaft protrudes into tank body from lower part, turns between tank body
Dynamic to be arranged, remaining powder is very inconvenient on cleaning tank body and agitating device, if thorough cleaning must dismantle rabbling mechanism,
The service efficiency of equipment very troublesome, also to reduce not only is used in this way.In addition speed reducer in this kind of structure, transmission belt,
The components such as rotary joint are needed from bottom installation, debugging, very inconvenient in the replacement and maintenance of components.
3, usual molding powder bonding device discharge nozzle intracavity section is circle, and discharging cover plate slidably reciprocates in circular tube chamber
When inevitably generate small rotation, the reason of rotation, can come from drive system, be also possible to be led by cover board shape
Cause, be easy to misfit sealed bottom in reactor tank in this way, cause material leak out, temperature anomaly, can pollute external equipment and
Generate caking phenomenon.
4, current bonding machines tank body generally uses inner barrel and outer barrel, and material is contained in inner cylinder, inner barrel and outer barrel it
Between close, be arranged in the enclosure space between inner barrel and outer barrel and cooling fin or be passed through cold/hot water, this tank body is in use
It was found that inner tank wall top is easily adhered material, due to having to the gravity whereabouts by material during bonding, so
There must be a certain distance between the intracorporal stirrer paddle upper surface of tank and tank body upper port plane, which results in materials in inner wall
The long-term adhesion on top adversely affects molding powder bonding process operation, also influences the actual effect of molding powder bonding, Er Qie
Replace can bring during the molding powders of other color batches it is cumbersome in cleaning.
