Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

In the description of the embodiments, the terms "disposed," "connected," and the like are to be construed broadly unless otherwise explicitly specified or limited. For example, the connection can be fixed, detachable or integrated; can be mechanically or electrically connected; either directly or through an intervening medium, or through internal communication between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1, the utility model discloses a high-efficient feeding device is used to injection molding machine, including base 10, hopper 20 and lid 30, be provided with the through-hole on the base 10, hopper 20 passes the through-hole, is provided with on the outer wall of hopper 20 and supports boss 22, supports boss 22 detachably and fixes on base 10. The bottom of hopper 20 is the toper, this conical receipts mouth department is discharge gate 21, lid 30 detachable sets up the one side of keeping away from base 10 at hopper 20, be provided with feed inlet 31 on the lid 30, still including being used for the (mixing) shaft 40 to the material stirring, the (mixing) shaft 40 is worn to establish in hopper 20 through the stirring shaft hole that sets up on the lid, the (mixing) shaft passes through actuating mechanism drive rotation, drive arrangement can select gear motor, servo motor etc. for use, this can make the adaptation according to actual need to technical personnel in the field and select, no longer describe herein.

As shown in fig. 2 to 4, the stirring shaft 40 includes a stirring main shaft 41 and a plurality of stirring support shafts 42, the plurality of stirring support shafts 42 are spirally and uniformly arranged on the outer wall of the stirring main shaft 41, both the stirring main shaft 41 and the stirring support shafts 42 are hollow shafts, and the hollow cavity of the stirring main shaft 41 is communicated with the hollow cavity of the stirring support shafts 42. In this kind of scheme, when feeding in raw materials, can stir the solid material in hopper 20 effectively through the stirring effect of stirring fulcrum 42, improved the speed and the stability of material from the discharge gate department ejection of compact, and then guaranteed the quality of injection moulding processing.

In addition, because the stirring main shaft 41 and the stirring support shaft 42 are both hollow shafts, and the hollow cavities of the stirring main shaft 41 and the stirring support shaft 42 are communicated in a penetrating manner, in the process of practical use, in order to further improve the stirring effect of the stirring shaft 40 on solid particles, high-pressure gas can be introduced from an opening of the stirring main shaft 41 close to one end of the cover body 30, and the high-pressure gas flows out from the tail end of the stirring support shaft and impacts the inner wall of the hopper 20, so that the material is prevented from being attached to the inner wall of the hopper.

When the inner wall of the hopper 20 needs to be cleaned, water or other liquid can be injected from the opening of the stirring main shaft 41 near one end of the cover body 30, the driving mechanism is not stopped to drive the stirring shaft 40, and the liquid flows out from the tail end of the stirring fulcrum shaft 42 to wash the inner wall of the hopper 20, so that the inner wall of the hopper 20 can be cleaned completely, and the labor intensity of workers is reduced.

In the above technical solution, when the materials attached to the inner wall of the hopper 20 need to be removed, high-pressure gas can be introduced into the hollow cavities of the stirring main shaft and the stirring fulcrum shafts to impact the materials on the side wall of the hopper 20, in the present embodiment, an arc-shaped scraper 43 is fixedly disposed at one end of each of the stirring fulcrum shafts 42 away from the stirring main shaft 41, and the hollow cavity of the stirring fulcrum shaft 42 penetrates through the scraper 43. In this arrangement, the raw material can be impacted by the high-pressure gas on the one hand, and scraped off by the scraper 43 from the inner wall of the hopper 20 on the other hand. Further reducing the adhesion of the raw materials to the inner wall of the hopper 20 and improving the discharging quality of the materials.

In order to stir the air outlet pressure at the end of the fulcrum 42, the end of the stirring main shaft 41 close to the discharge port 21 is of a sealed structure, and the impact on the raw material in the hopper can be more effective due to the increase of the air outlet pressure. As a more preferable scheme, one end of the stirring main shaft 41 close to the discharge port 21 is detachably provided with a blocking block. When the residual liquid in the cavity of the stirring main shaft 41 needs to be discharged, the plugging block can be detached, and the plugging block can be installed again after the residual liquid in the stirring main shaft is completely discharged.

One important reason for the blockage of the discharge opening 21 of the hopper 20 during the charging process is that the material enters from the feed opening 31 and falls into the discharge opening 21 under the action of gravity, and a large amount of material rushes into the discharge opening 21 at a high speed. In the present embodiment, the stirring support shaft 42 is provided with the striker plate 44 at an interval, one end of the striker plate 44 is fixed to the stirring support shaft 42, and the other end is disposed obliquely downward. The striker plate can assist the material in hopper 20 to stir on the one hand, and on the other hand falls on following stirring main shaft 41 pivoted striker plate 44 from the material that feed inlet 31 got into, can disperse effectively, avoids a large amount of materials to concentrate on discharge gate 21 department and takes place to block up. The number of the striker plates can be set according to actual needs, and the striker plates can be used for effectively dispersing materials entering the feed inlet 31.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention. In addition, the technical solutions between the various embodiments can be combined with each other, but must be based on the realization of those skilled in the art; when the technical solutions are contradictory or cannot be combined, the combination of the technical solutions should be considered to be absent, and is not within the protection scope of the present invention.
