The screw rod in the screw extruder is one of very important parts, and the double-rotation direction threaded rod is adopted in the double-rotation direction extruder, and the diameter and the screw pitch of the existing double-rotation direction screw rod structure are of a single size, so that an object cannot be extruded step by step.
Based on the above situation, the utility model provides a double-rotation-direction threaded rod which can effectively solve the problems.
Disclosure of Invention
The utility model aims to provide a double-rotation-direction threaded rod. The double-rotation-direction threaded rod is simple in structure and convenient to use, and because the left screw rod and the right screw rod are of conical structures, and the screw pitch is gradually reduced from the feeding end to the discharging end, the object is extruded gradually, and the working efficiency is improved.
The utility model is realized by the following technical scheme:
the utility model provides a two spiral to threaded rod, includes left end, left screw rod, connecting axle, right screw rod and the right end that connect gradually, left screw rod and right screw rod all are the toper structure, just be equipped with the spiral on left screw rod and the right screw rod.
The utility model aims to provide a double-rotation-direction threaded rod. The double-rotation-direction threaded rod is simple in structure and convenient to use, and because the left screw rod and the right screw rod are of conical structures, and the screw pitch is gradually reduced from the feeding end to the discharging end, the object is extruded gradually, and the working efficiency is improved.
Preferably, the connecting shaft is provided with a first through hole.
Preferably, a second through hole is formed in the left screw.
Preferably, a third through hole is formed in the right screw.
Preferably, the diameters of the left screw and the right screw gradually decrease from the feeding end to the discharging end.
Preferably, the pitches of the left screw and the right screw are gradually reduced from the feeding end to the discharging end.
Compared with the prior art, the utility model has the following advantages:
the double-rotation-direction threaded rod is simple in structure and convenient to use, and because the left screw rod and the right screw rod are of conical structures, and the screw pitch is gradually reduced from the feeding end to the discharging end, the object is extruded gradually, and the working efficiency is improved.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a schematic view of the structure of the left end or the right end of the present utility model.
Detailed Description
In order that those skilled in the art will better understand the technical solutions of the present utility model, preferred embodiments of the present utility model will be described below with reference to specific examples, but it should be understood that the drawings are for illustrative purposes only and should not be construed as limiting the present patent; for the purpose of better illustrating the embodiments, certain elements of the drawings may be omitted, enlarged or reduced and do not represent the actual product dimensions; it will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The positional relationship depicted in the drawings is for illustrative purposes only and is not to be construed as limiting the present patent.
Example 1:
as shown in fig. 1 to 2, the utility model provides a double-rotation-direction threaded rod, which comprises a left end part 1, a left screw rod 2, a connecting shaft 3, a right screw rod 4 and a right end part 5 which are sequentially connected, wherein the left screw rod 2 and the right screw rod 4 are in conical structures, and the left screw rod 2 and the right screw rod 4 are provided with screws 6. The left end part 1 and the right end part 5 are provided with exhaust holes 11.
Example 2:
as shown in fig. 1 to 2, the utility model provides a double-rotation-direction threaded rod, which comprises a left end part 1, a left screw rod 2, a connecting shaft 3, a right screw rod 4 and a right end part 5 which are sequentially connected, wherein the left screw rod 2 and the right screw rod 4 are in conical structures, and the left screw rod 2 and the right screw rod 4 are provided with screws 6.
Further, in another embodiment, the connecting shaft 3 is provided with a first through hole 31.
Further, in another embodiment, the left screw 2 is provided with a second through hole 21.
Further, in another embodiment, the right screw 4 is provided with a third through hole 41.
Due to the arrangement of the through holes, the extrusion device is not easy to coagulate when extruding objects, and improves extrusion efficiency.
Further, in another embodiment, the left screw 2 and the right screw 4 have diameters gradually decreasing from the feeding end to the discharging end.
Because the diameter gradually decreases, the extrusion force is gradually increased, and a better extrusion effect is realized.
Further, in another embodiment, the left screw 2 and the right screw 4 have pitches gradually decreasing from the feeding end to the discharging end.
Since the pitch is gradually reduced, the extrusion effect of the screw 6 on the article can be gradually improved.
The double-turn threaded rod of the present utility model can be easily manufactured or used by those skilled in the art from the description of the present utility model and the accompanying drawings, and can produce the positive effects described in the present utility model.
Unless specifically stated otherwise, in the present utility model, if there are terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the positional relationship indicated is based on the positional relationship indicated in the drawings, and is merely for convenience of describing the present utility model and simplifying the description, and it is not necessary to indicate or imply that the referred devices or elements must have a specific orientation, be constructed and operated in a specific orientation, so that the terms describing the positional relationship in the present utility model are merely for exemplary illustration and should not be construed as limitations of the present patent, and it is possible for those skilled in the art to understand the specific meaning of the above terms in conjunction with the drawings and according to the specific circumstances.
