Abstract
The utility model discloses a uniform charging device for producing a thin film. The uniform charging device comprises a rack, wherein the rack is provided with a spiral feeder; a discharging end of the spiral feeder is connected into a reaction kettle; a discharging hopper is arranged above the spiral feeder and the lower end of the discharging hopper is provided with a vertical cylindrical material pushing channel; the discharging opening of the cylindrical material pushing channel downwards extends to the feeding opening of the spiral feeder; the material pushing channel is internally and axially provided with a material pushing rotary shaft; the upper end of the material pushing rotary shaft stretches out of the discharging hopper and is in transmission connection with a motor; and a material pushing blade is wound on the material pushing rotary shaft around an axial spiral disc. The uniform charging device disclosed by the utility model is simple and reasonable in structure; the design that the material pushing channel is arranged at the lower end of the discharging hopper and the material pushing channel is internally provided with the material pushing shaft provided with the spiral material pushing blade is adopted, so that the feeding uniformity and accuracy of materials are effectively guaranteed and phenomena of discontinuous and unsmooth discharging are not easy to happen; and the materials are effectively prevented from being damped and going bad, and being oxidized, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of film production equipment, is specially the even feeding device of a kind of film production.
Background technology
Film is a kind of thin and soft transparent sheet, is made by plastics, adhesive, rubber or other materials, is widely used in industries such as electronic apparatus, machinery, printing.In the production process of Kapton, during the precursor resin of synthesis of polyimides, need that the control material drops into evenly continuously and accuracy, to guarantee also that simultaneously material is not oxidized and do not become damp and rotten in reinforced process.Existing feeding device structure is reasonable inadequately on the market at present, can not guarantee uniformity and the accuracy of feeding in the reinforced process, when especially inventory is too much, cause blanking discontinuous easily, have some setbacks, and material becomes damp and rotten and oxidized easily, influence production efficiency.
The utility model content
The purpose of this utility model provides the even feeding device of a kind of film production, reasonable inadequately to solve feeding device structure traditional in the prior art, uniformity and the accuracy of feeding can not have been guaranteed in the reinforced process, when especially inventory is too much, cause blanking discontinuous easily, have some setbacks, and material becomes damp and rotten and oxidized easily, influence the problem of production efficiency.
For achieving the above object, the technical solution adopted in the utility model is:
The even feeding device of a kind of film production, include frame, on the described frame feeding screw is installed, the discharge end of described feeding screw inserts reactor, it is characterized in that: described feeding screw top is provided with hopper, described hopper lower end is provided with a vertical tubular pusher passage, the discharging opening of described tubular pusher passage extends downwards in the charging aperture of feeding screw, be axially arranged with the pusher rotating shaft in the described pusher passage, described pusher rotating shaft upper end is stretched out hopper and is connected with motor, and axial screw coiling in described pusher rotating shaft upper edge has pusher blade.
The even feeding device of described a kind of film production is characterized in that: leave the gap between described pusher blade outward flange and the pusher vias inner walls.
The beneficial effects of the utility model are:
The utility model is simple and reasonable; easy to install; employing arranges the pusher passage in the hopper lower end; and in the pusher passage, be provided with the design of the pusher rotating shaft of helical form pusher blade; feeding uniformity and the accuracy of material have been guaranteed effectively; and the phenomenon that blanking is discontinuous, have some setbacks be difficult for to take place, protected effectively material do not become damp and rotten, oxidized, improved production efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the even feeding device of a kind of film production, include frame 1, feeding screw 2 is installed on the frame 1, the discharge end of feeding screw 2 inserts reactor 3, feeding screw 2 tops are provided with hopper 4, hopper 4 lower ends are provided with a vertical tubular pusher passage 5, the discharging opening of tubular pusher passage 5 extends downwards in the charging aperture of feeding screw 2, be axially arranged with pusher rotating shaft 6 in the pusher passage 5, pusher rotating shaft 6 upper ends are stretched out hopper 4 and are connected with motor 7, and pusher rotating shaft 6 upper edge axial screw coilings have pusher blade 8.
Leave the gap between pusher blade 8 outward flanges and pusher passage 5 inwalls.
Claims (2)
