Description
Technical Field
The invention relates to the field of machinery, in particular to a feeding system of an injection molding machine for food packaging barrels.
Background
When the food packaging barrel is subjected to injection molding production, air is easily involved in feeding the food packaging barrel. This leads to the back air of moulding plastics in food package barrel's material, leads to its overall structure intensity lower, the easy leak that appears. Some people set a negative pressure structure in order to reduce the content of bubbles, but because the particles are in the process of initially entering the material, gaps are formed among the particles, and therefore the bubbles are easily wrapped in the material when the material is molten. It is difficult to remove the gas included in the melting by merely providing the negative pressure structure.

The invention has simple structure and convenient use, ensures that bubbles coated after melting overflow and disperse upwards through the inclined baffle plate, the vibrator and the L-shaped feeding pipeline, prevents new gas from being coated when the material moves, and effectively extrudes the gas in the L-shaped feeding pipeline due to small inner diameter of the L-shaped feeding pipeline.
The purpose of the invention is realized by the following technical scheme:
a feeding system of an injection molding machine for food packaging barrels comprises a spiral feeder, wherein a shell of the spiral feeder is conical; the heater is wrapped and fixed at the tail end of the shell; an inclined baffle which is gradually inclined downwards along the feeding direction is formed at the tail end of the shell, and the bottom of the tail end of the shell is communicated with the injection molding machine body through an L-shaped feeding pipeline; the inner diameter of the tail end of the shell is larger than that of the L-shaped feeding pipeline; the middle part of the spiral feeder is communicated with a negative pressure cavity through a plurality of micropores, and the negative pressure cavity is provided with a first negative pressure pump through a communicating pipe.
In a further improvement, the housing is provided with a vibrator.
The top of the feed port of the spiral feeder is communicated with a storage tank, and an air suction port and the feed port are formed on the storage tank; the air suction port is communicated with a second negative pressure pump; the feed inlet is provided with a valve.
In a further improvement, the air suction port and the communicating pipe are both provided with one-way valves.
In a further improvement, the corners of the L-shaped feed pipe are rounded.
In a further refinement, the heater is an electric heater.
The invention has the beneficial effects that:

Drawings
The invention is further illustrated by means of the attached drawings, the content of which is not in any way limitative of the invention.
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.
Example 1
As shown in fig. 1, the feeding system of the food packaging barrel injection molding machine comprises a screw feeder 1, a housing 2, a heater 3, an inclined baffle 4, an L-shaped feeding pipeline 5, an injection molding machine body 6, a micropore 7, a negative pressure cavity 8, a first negative pressure pump 9, a vibrator 10, a feeding port 11, a storage tank 12, an air suction port 13, a feeding port 14, a second negative pressure pump 15, a valve 16, a one-way valve 17 and a communicating pipe 18.
Wherein, the top of the feed inlet 11 of the screw feeder 1 is communicated with a storage tank 12, and an air suction port 13 and a feed inlet 14 are formed on the storage tank 12; the suction port 13 is communicated with a second negative pressure pump 15; the feed port 14 is provided with a valve 16. The shell 2 is conical; the heater 3 is wrapped and fixed at the tail end of the shell 2; an inclined baffle 4 which is gradually inclined downwards along the feeding direction is formed at the tail end of the shell 2, and the bottom of the tail end of the shell 2 is communicated with an injection molding machine body 6 through an L-shaped feeding pipeline 5; the inner diameter of the tail end of the shell 2 is larger than that of the L-shaped feeding pipeline 5; the middle part of the screw feeder 1 is communicated with a negative pressure cavity 8 through a plurality of micropores 7, and the negative pressure cavity 8 is provided with a first negative pressure pump 9 through a communicating pipe 18. A vibrator 10 is mounted on the housing 2. Check valves 17 are mounted on the suction port 13 and the communication pipe 18. The corners of the L-shaped feed conduit 5 are rounded.
When the invention is used, materials enter the spiral feeder 1 from the material storage tank 12, meanwhile, the second negative pressure pump 15 sucks air under negative pressure, air entering the spiral feeder 1 is reduced, the spiral feeder 1 sends the materials to the tail end and heats and melts the materials, because the shell 2 is conical, the air stirred in the materials gradually overflows upwards during melting under the vibration of the vibrator 10, the air in the shell can overflow and disperse in the reverse direction of the advancing direction of the materials along the shell 2 when being heated, the air is sucked out by the first negative pressure pump 9, the material entering tail end is blocked by the inclined baffle 4, and the air is light and floats above, so the materials entering the L-shaped feeding pipeline 5 basically have no air, thereby effectively avoiding air bubbles in the obtained mould and improving the quality of the mould.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
