Description

Technical Field

[0001] The utility model relates to a crank structure, in particular to a crank structure used for forming a ring. Background Art

[0002] When the long ring steamer is blowing steam on the cloth, the cloth is hung on the cloth hanging roller. When the cloth hanging roller changes direction on the long ring, a finger is generally used to move the cloth hanging roller to turn it. The crank connected to the cloth hanging roller only swings as a connecting structure. When it is moved, the crank may not swing into place because the connection between the crank and the cloth hanging roller is stuck, resulting in the cloth hanging roller being unable to get into place and the cloth being unable to form a loop. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides a crank structure for forming a ring, which can ensure the correct swing of the crank.

[0004] To achieve this purpose, the structure adopted by the utility model is: a crank structure for forming a ring, including a cloth hanging roller segment, a connecting segment and a rotating segment. The cloth hanging roller segment and the rotating segment are parallel to each other, the connecting segment is inclined, one end of the connecting segment is connected to the cloth hanging roller segment, and the other end is connected to the rotating segment. The overall structure is Z-shaped, the top of the cloth hanging roller segment is connected to the cloth hanging roller through a pin shaft, one side of the bottom of the rotating segment is connected to the transmission chain through a rotating shaft, and a convex angle is provided on the other side, and the convex angle protrudes obliquely downward from the rotating segment.

[0005] The beneficial effects are as follows: the structural design of the utility model is reasonable and ingenious. After the convex corner of the rotating section hits the ring-forming block provided on the long-ring steamer, the crank cannot continue to move forward and can only rotate. When it is rotated into place, the convex corner changes direction and the crank can leave the ring-forming block and continue to move forward, thereby ensuring that the crank drives the cloth hanging roller to rotate accurately. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The present invention will be described by way of examples with reference to the accompanying drawings, in which:

[0007] Figure 1 It is a front view of the utility model;

[0008] Figure 2 It is a side view of the utility model. DETAILED DESCRIPTION

[0009] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0010] In the description of the utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0011] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components; the fixed connection can be welding or gluing. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0012] like Figure 1 , Figure 2 The crank structure for forming a ring shown in the figure comprises a cloth hanging roller segment 1, a connecting segment 2 and a rotating segment 3. The cloth hanging roller segment 1 and the rotating segment 3 are parallel to each other, the connecting segment 2 is tilted, one end of the connecting segment 2 is connected to the cloth hanging roller segment 1, and the other end is connected to the rotating segment 3, and the overall structure is in a Z-shaped structure. The top of the cloth hanging roller segment 1 is connected to the cloth hanging roller 5 through a pin shaft, one side of the bottom of the rotating segment 3 is connected to the transmission chain 6 through a rotating shaft, and a convex angle 4 is arranged on the other side, and the convex angle 4 protrudes obliquely downward to the rotating segment 3. In the process of the crank driving the cloth hanging roller forward, the rotating segment 3 is in front and the cloth hanging roller segment 1 is in the back. After the convex angle 4 of the rotating segment 3 hits the ring forming block set on the long ring steamer, the crank cannot continue to move forward. Driven by the transmission chain 6, the crank can only rotate. When it rotates to the right position, the convex angle 4 changes direction to avoid the ring forming block, and the crank can leave the ring forming block and continue to move forward, ensuring the accurate rotation of the cloth hanging roller driven by the crank.

[0013] The above is based on the enlightenment of this utility model. Through the above description, relevant staff can make various changes and modifications without deviating from the technical concept of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
