Abstract
The utility model discloses a plastic grain feeding device, comprising an air amplifier. The air amplifier comprises a first shell, a slope air guide piece and a second shell, which are internally communicated with one another by through holes, wherein the slope air guide piece is internally arranged between the first shell and the second shell, an air inlet is formed in the side wall of the first shell, a ring-shaped cavity is formed between a slope of the air guide piece and the first shell, compressed air enters the ring-shaped cavity through the air inlet, flows through the ring-shaped through holes at high speed and then flows out of the second shell, the through holes in the slope air guide piece and the first shell form a low pressure area, and a great quantity of light plastic grains are absorbed into the through holes and then are converged with air flow to form high-speed material flow to fill a charging barrel of an injection molding machine from the second shell through a feeding pipe.
Description
Technical field
According to hydromechanical basic principle---wall attachment effect (Coanda Effects), only with a small amount of compressed air as power source, drive surrounding air flow formation high pressure, high velocity air, flow is air consumption 50 times.Compressed air is after air inlet flows into annular chamber, high velocity stream is crossed nozzle ring, this strand of primary airstream is adsorbed on the surface of profile, so produce a low-pressure area in cavity center, thereby around a large amount of air is inhaled into, after converging, primary airstream and around air-flow just form at a high speed, the air-flow of high power capacity flows out from air amplifier.
What in the barrel jettison system on existing injection machine, use is all adsorption mechanism, and concrete structure automatic suction machine as disclosed in [CN102601964A], includes suction cylinder, suction tube, air intake duct, compressed air inlet pipe and vacuum machine etc. as shown in Figure 1.In the time of work, suction tube one end is placed in material storage tube, vacuum machine starts, after admission air valve is opened, in suction cylinder, produce negative pressure, suction tube to feed supplement in suction cylinder, is controlled suction time and flow process by control panel under suction function, only needs replacing that a workman is responsible for material storage tube just.Such scheme utilizes vacuum machine compressed air to produce negative pressure and realizes suction operation, and structure is relatively complicated, and suction tube and air intake duct, also need to connect power supply, and whole equipment cost is higher.
In plastic pellet charging equipment, do not have to utilize the fluid mechanics principle of setting forth before to realize the precedent of the conveying of raw material, for solving this technological gap, therefore in this field, plastic pellet feeding device is carried out to architecture advances.
Background technology
The utility model relates to and using on injection machine, barrel inside is carried out to the equipment of filler, is specially plastic pellet feeding device.
Utility model content
The purpose of this utility model is to provide a kind of plastic pellet feeding device, and it is simple in structure, equipment cost is low, and material loading safely and fast.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of plastic pellet feeding device, include an air amplifier, it is characterized in that: described air amplifier includes the first housing that interior bone communicates, inclined-plane air-guide part and the second housing, inclined-plane air-guide part is built between the first housing and the second housing, junction is provided with sealing ring, the first housing is realized and being connected by screw thread with the second housing, on the sidewall of the first housing, there is air inlet, above-mentioned air inlet is corresponding to the inclined-plane of air-guide part, between the inclined-plane of air-guide part and the first housing, form annular chamber, air-guide part top annular is provided with a plurality of through holes annular chamber is communicated with the second housing through-hole, external compression air is connected with air amplifier air inlet by conduit, the second housing communicates with barrel inner chamber by feed pipe.
Further, first described enclosure interior through hole one end flare,
Further, the second described enclosure interior through hole contacts one end flare with inclined-plane air-guide part, and air-guide part top, inclined-plane through hole has angle of inclination.
Further, described angle of inclination is consistent with the bevel angle of inclined-plane air-guide part.
Further, described compressed air is controlled compressed-air actuated opening and closing by time controller.
Adopt a kind of plastic pellet feeding device of said structure, utilize air amplifier principle, external compression air by conduit in air inlet enters into annular chamber, high velocity stream is crossed annular through-hole and is flowed out from the second housing, in the interior bone of inclined-plane air-guide part and the first housing, form low-pressure area, therefore the light plastic grain of the tubaeform port of the first housing by a large amount of suction after with air-flow converge formation high-velocity stream from the second housing in feed pipe is filled into injecting machine material tube.
The utlity model has following advantage: feeding device only need to be placed in storage vat, utilize external compression air as material loading power, without connecting power supply, only need to change storage vat and just can continue material loading, compare that original adsorption mechanism structure is simpler, equipment cost reduces greatly, and easy to operate, material loading is safety again fast.
