Technical Field
The utility model relates to a spiral feeding structure capable of feeding accurately, and belongs to the technical field of glass batching systems.
Background
In the weighing process of glass batching production line, under the better condition of material fluidity, the influence of screw feeder's feed accuracy to weighing the precision is great, and conventional screw feeder's helical blade and hob are isometric, and flush basically with the scroll cover tip, can be so because helical blade's rotation, the material in the blade is whole to be brought into the weighing hopper by the blade, and partial material adhesion is on the blade, can probably lump during the ejection of compact and drop, leads to the precision of feed not high.
SUMMERY OF THE UTILITY MODEL
According to the defects in the prior art, the technical problems to be solved by the utility model are as follows: the spiral feeding structure for accurate feeding is provided, and the spiral feeding structure is powder accurate feeding equipment with good fluidity.
The utility model relates to a spiral feeding structure for accurate feeding, which comprises a spiral shaft and a spiral casing which are concentrically arranged, wherein a spiral blade is arranged on the spiral shaft, a feeding hole is arranged on the spiral casing, the tail end of the spiral casing is connected with a measuring hopper, the spiral shaft and the spiral blade are completely positioned in the spiral casing, and the length of the spiral casing is longer than that of the spiral shaft, so that the spiral shaft and the spiral blade do not extend out of the end part of the spiral casing.
Further, the length of the spiral shaft is longer than that of the spiral blade.
The tail end of the spiral casing is provided with a discharge valve.
The spiral shaft is coaxial with the motor spindle and is driven to rotate by the motor.
According to the utility model, the spiral rod does not extend out of the end part of the spiral casing, a certain distance is reserved between the spiral rod and the end part, the size of the spiral blade and the end part of the spiral casing is larger, the whole spiral rod and the blade are positioned in the spiral casing, and the spiral rod and the blade are not arranged in the outlet of the spiral casing within a certain distance. Therefore, when powder is conveyed, the materials at the front end of the screw rod are not stirred by the screw blades, the materials at the rear part are pushed to move forwards slowly, the materials drop into the weighing hopper a little by a little, the rotating shaft end without the blades can prevent the powder from being blocked after being gathered, the possibility of large-volume collapse and falling of the materials is reduced, and the feeding precision is increased.
Compared with the prior art, the utility model has the beneficial effects that:
according to the spiral feeding structure for accurate feeding, a spiral structure is completely built in through reasonable structural design, the spiral rod does not extend out of the end part of the spiral casing, a certain distance is reserved between the spiral rod and the end part, the size of the spiral blade and the end part of the spiral casing is larger, materials at the front end of the spiral casing are not stirred by the spiral blade and slide into the weighing hopper evenly and stably, large blocks of the materials are not stirred into the weighing hopper any more, the stability of ingredient weighing is guaranteed, and the problem of low feeding precision is solved thoroughly.
Drawings
Fig. 1 is a schematic structural view of the present invention.
In the figure: the spiral shaft 1, the helical blade 2, the spiral shell 3, the discharge valve 4, the weighing hopper 5, the feed inlet 6.
Detailed Description
The utility model is further illustrated by the following specific examples. However, in the description of the present invention, it should be noted that the terms "front end", "rear end", "left and right", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "communicating" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
As shown in fig. 1, the screw feeding structure of accurate feeding of the present invention includes a screw shaft 1 and a screw casing 3 concentrically arranged, the screw casing 3 is a sleeve pipe which is a material flow passage, and the tail end of the sleeve pipe is provided with a discharge valve 4. The screw shaft 1 is coaxial with a motor main shaft and is driven to rotate by a motor. The spiral shaft 1 is provided with spiral blades 2, the rotation direction is positive rotation or negative rotation, the spiral blades are welded on the spiral shaft 1, the spiral casing 3 is provided with a feeding hole 6, and the tail end of the spiral casing 3 is connected with a measuring hopper 5.
Wherein, the screw shaft 1 and the screw blade 2 are completely positioned in the screw casing 3, the length of the screw casing 3 is longer than that of the screw shaft 1, and the length of the screw shaft 1 is longer than that of the screw blade 2, so that the screw shaft 1 and the screw blade 2 do not extend out of the end part of the screw casing 3.
For ease of understanding, the operation or working principle of the present embodiment is given below:
the material flows into the feeder from the feed inlet 6, and reaches the outlet along with the rotation of the spiral shaft 1 of the feeder, the flowing material naturally forms a slope surface without being stirred by the spiral blade 2, and stably and slowly falls into the weighing hopper 5 under the propelling of the following material, and the lower the spiral rotating speed, the smaller the material flow and the more accurate the feeding. And the rotating shaft end without the blade can prevent the powder from being blocked after being gathered. The material is fed by a screw to the weighing hopper 5, and the weighing hopper 5 measures the weight of the feed. When the screw feeding is completed, the discharge valve 4 is closed to prevent the material from falling continuously.
Of course, the foregoing is only a preferred embodiment of the utility model and should not be taken as limiting the scope of the embodiments of the utility model. The present invention is not limited to the above examples, and equivalent changes and modifications made by those skilled in the art within the spirit and scope of the present invention should be construed as being included in the scope of the present invention.
