Description
Technical field
The utility model relates to the technical field of processing film equipment, more specifically, relates to a kind of casting films production equipment.
Background technology
Casting films is a kind of tensionless winkler foundation, the nondirectional flat crowded film produced by the quenching of melt curtain coating, is divided into simple curtain coating and multi-layer co-extruded curtain coating two kinds.The cast film production of China is started late, basis is comparatively weak, but development speed is very fast, and grow through the developments of nearly 20 years, cast film processing industry has had the rising industry of suitable production capacity and the level of production in the packaging industry of China.
In casting machine field, the automaticity of China's cast film line, still need and will improve further in the aspects such as the stability of production line, whole production line arranges the unreasonable production efficiency that causes low, and the powder of domestic cast film line and virgin material agitating device are all with vertical mixing, this agitating device is due to the mixing of powder and new pellet, easily plug stirring port, powder and blanking is made to occur the phenomenon of building bridge, the having some setbacks thus cause Screw Extrusion pressure transient of blanking, affect the thickness of casting films product, even there is the phenomenon of disconnected film, cause the stopping of production, make production efficiency low.
Utility model content
Technical problem to be solved in the utility model provides a kind of casting films production equipment for prior art present situation, the cast film line master-plan arrangement of solution China is unreasonable, production efficiency is low, and to solve in cast film line extrusion system because the mixing of powder and virgin material easily blocks stirring port, make powder and blanking occur the problem of building bridge.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of casting films production equipment, comprise frame, described erecting is equipped with extrusion system, casting apparatus is disposed with below described extrusion system, thickness measuring system, traction fork system, winding system and unload film device, described extrusion system includes feeding device, described feeding device comprises the first hopper and the second hopper that vertically arrange successively, the discharging opening of described first hopper is located in the second hopper, the feeding mouth of described first hopper is connected to cyclone separator, screw rod is provided with in described first hopper, described screw rod comprises helical screw agitator section for stirring powder and for carrying powder to the screw rod transmission section in extruder, described second hopper side has been communicated with virgin material tremie pipe.
The utility model is by the extrusion system in cast film line field, casting apparatus, thickness measuring system, the layout of traction fork system and winding system has carried out appropriate design, and the powder in extrusion system feeding device is stirred after entering the first hopper under the effect of helical screw agitator section, add that self gravitation affects, extruder can be delivered into by conveying screw rod section is stable when being stirred, virgin material then falls into the second hopper and enters extruder, then powder and new pellet mix and blend in the screw rod of extruder is good, enter plastic screw to melt extrude.This avoid powder and virgin material carries out stirring the problem causing blocking stirring port in hopper.
Described screw rod is driven by stirring motor and rotates, and described stirring motor is located on the first hopper.
Described first hopper shape is del.Can ensure that powder is stirred fully further like this, and contribute to powder and move to the first hopper discharging opening.
Cast film line also can produce a large amount of casting films waste material rim charge in high speed manufacturing processes; domestic is adopt disintegrating machine directly the rim charge of casting films to be collected and pelletizing; but in the process of pelletizing; because the plastic foil pulverized is assembled in screen cloth there; easy blocking mesh; cause thin film leftover material can not be drawn into disintegrating machine by continuous print; and pile up in cast film line there; thus cause cast film line to stop producing; often repeatedly to start shooting shutdown, cause the low of production efficiency and waste raw material.
Described extrusion system further comprises offcut recover system for this reason, described offcut recover system comprise draw rim charge pipeline, with draw the device for suction material that rim charge pipeline is connected and the disintegrating machine be connected with device for suction material, described device for suction material comprises negative-pressure ward case, fumer and negative-pressure ward blower fan, the inlet scoop of described negative-pressure ward blower fan is connected with fumer, the air outlet of described negative-pressure ward blower fan is connected with negative-pressure ward case, described negative-pressure ward case connects fumer and disintegrating machine successively by discharge nozzle, described negative-pressure ward case also with draw rim charge pipeline and be connected.
Piling up problem the utility model for the rim charge easily produced in casting films high speed manufacturing processes adopts the Inner eycle suction system be interconnected to constitute by negative-pressure ward case, fumer and negative-pressure ward blower fan three to aspirate rim charge, be specially: negative-pressure ward blower fan is drawn into negative-pressure ward case by inlet scoop the air pressure of fumer, negative-pressure ward case produces air blast and supplements fumer, thus forms Inner eycle suction system.
Specifically have employed two kinds of technical schemes in the utility model:
One be described discharge nozzle is one, and it runs through fumer, and the pipeline section being positioned at fumer has several pores.When negative-pressure ward blower fan carries out exhaust to fumer time, the air-flow of negative-pressure ward case is supplemented by the hole of discharge nozzle, and the benefit of this technical scheme is that rim charge can by air blast effect quickly through negative-pressure ward case and fumer, and negative-pressure ward blower fan can not be sucked into, also not having rim charge remains in fumer;
