Description

Technical Field

[0001] This utility model relates to the field of yarn processing equipment, and in particular to a cradle structure for clamping yarn spools. Background Technology

[0002] In existing yarn processing equipment, such as doubling machines and beam looms, the bobbin-shaped yarn needs to be placed on a structure that restricts its position and aids in rotation, typically a cradle-like structure, as shown in patent CN203583076U. During the use of the cradle, the yarn bobbin needs to be picked up and put down, requiring the cradle to swing up and down. While existing cradles can swing up and down, they are difficult to stabilize, especially after being raised to a certain height, relying solely on cylinders for support, which poses a safety hazard. Furthermore, the overall mass of the cradle plus the fully wound yarn bobbin is considerable, making it prone to danger when falling. Therefore, a cradle structure that can stably support and clamp the yarn bobbin is needed. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies and provide a cradle structure for clamping spools.

[0004] To solve the above problems, the present invention adopts the following solution:

[0005] A cradle structure for clamping a bobbin includes a bobbin for abutting the bobbin and a rocker arm, wherein the bobbin is rotatably mounted on the rocker arm; it also includes a fixed connecting shaft and a limiting structure; the limiting structure includes a limiting plate and a limiting rod, the limiting rod being slidably mounted on the rocker arm, and the limiting plate being fixedly mounted on the connecting shaft; the limiting rod and the limiting plate are correspondingly arranged, and the limiting plate is provided with at least one limiting hole corresponding to the limiting rod; a first elastic element is also provided between the limiting rod and the rocker arm to push the limiting rod towards the limiting plate; the rocker arm is rotatably mounted on the connecting shaft, and when the rocker arm rotates, it drives the limiting rod to rotate.

[0006] Furthermore, the limiting rod and the rocker arm are connected by an extended rod-shaped structure, and the rod-shaped structure is fixedly connected to the rocker arm; at least one sliding hole is provided on the rod-shaped structure, and the limiting rod is slidably disposed in one of the sliding holes.

[0007] Furthermore, the limiting plate is generally fan-shaped; the limiting plate is provided with at least one arc-shaped sliding groove, and at least one positioning hole is provided on the path or end of the sliding groove.

[0008] Furthermore, the center of the limiting plate is provided with a through hole for fixed connection with the connecting shaft, and threaded holes for fastening are provided on the upper and lower sides of the through hole respectively.

[0009] Furthermore, the limiting rod limiting plate is located on the side of the rod-shaped structure near the limiting disc; a first elastic element is provided between the second limiting plate and the rod-shaped structure.

[0010] Furthermore, the end of the limiting rod is rounded; the groove on the limiting plate is an arc-shaped groove that mates with the rounded end of the limiting rod; a limiting hole is provided at the bottom end or near the bottom end of the arc-shaped groove.

[0011] Furthermore, the rocker arm includes an L-shaped fixed arm and a plate-shaped rotating arm; the rotating arm is rotatably disposed at one end of the fixed arm; a coil is rotatably disposed on the fixed arm, and a coil is also disposed on the side of the rotating arm opposite to the fixed arm; the two coils are disposed opposite to each other.

[0012] Furthermore, a second elastic element is provided between the rotating arm and the fixed arm to pull the rotating arm toward the fixed arm.

[0016] By setting a limit plate in conjunction with a limit rod on the rocker arm, the rocker arm can be fixed by inserting the limit rod into the limit hole on the limit plate after rotating to a set angle. The stable mechanical connection structure ensures the safety of personnel operation.

[0017] By setting the slide groove as an arc-shaped groove, and matching the round head at the end of the limiting rod, the limiting rod can slide smoothly in the slide groove. In conjunction with the limiting hole set in the slide groove, the rocker arm can be fixed at different heights.

[0018] By setting a second elastic element, the rotating arm and the fixed arm can keep the coil clamped. In conjunction with the support rod, the minimum rotation angle of the rotating arm is limited, thus preventing it from colliding with the fixed arm. Attached Figure Description

[0024] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0025] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the figures only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0026] Example 1:

[0027] like Figures 1-4 As shown, a rocker arm structure for clamping a bobbin 5 includes a bobbin 1 for abutting the bobbin 5 and a rocker arm 2, wherein the bobbin 1 is rotatably mounted on the rocker arm 2; it also includes a fixed connecting shaft 3 and a limiting structure 4; the connecting shaft 3 is fixedly mounted on an external tabletop, and the connecting shaft 3 is used to rotatably connect the rocker arm 2, so that the rocker arm 2 can rotate around the connecting shaft 3; the limiting structure 4 includes a limiting plate 41 and a limiting rod 42, the limiting rod 42 is slidably mounted on the rocker arm 2, and the limiting plate 41 is fixedly mounted on the connecting shaft 3; the limiting rod 42 and the limiting plate 41... Correspondingly, the limiting plate 41 is provided with at least one limiting hole 411 corresponding to the limiting rod 42; a first elastic element 421 is also provided between the limiting rod 42 and the rocker arm 2 to push the limiting rod 42 toward the limiting plate 41; the rocker arm 2 is rotatably mounted on the connecting shaft 3; when the rocker arm 2 rotates, it drives the limiting rod 42 to rotate. When the limiting rod 42 rotates to the position of the corresponding limiting hole 411 on the limiting plate 41, the first elastic element 421 pushes the limiting rod 42 into the limiting hole 411, thereby achieving a locking action and fixing the rocker arm 2.

[0028] The limiting plate 41 is generally fan-shaped. At least one arc-shaped groove 412 is provided on the limiting plate 41, and at least one positioning hole 411 is provided on the path or end of the groove 412. In this example, the limiting plate 41 has two grooves 412, and different positioning holes 411 are provided on the two grooves 412 corresponding to different angles of the rocker arm 2. This allows the limiting rod 42 to be fixed at different rotation angles when corresponding to different grooves 412, so that the bobbin 5 stops at different heights to meet different process requirements. The center of the limiting plate 422 is provided with a through hole for fixed connection to the connecting shaft 3. The center of the arc-shaped groove 412 coincides with the axis of the connecting shaft 3, so that when the rocker arm 2 rotates around the connecting shaft 3, the limiting rod 42 on the rocker arm 2 can slide along the groove 412. Threaded holes for fastening are provided on the upper and lower sides of the through hole of the limiting plate 422. Through the threaded connection, the limiting rod 42 and the connecting shaft 3 are fixed together.

[0029] The limiting rod 42 is connected to the rocker arm 2 via an extended rod-like structure 21. The rod-like structure 21 is fixedly connected to the rocker arm 2. It should be noted that the rod-like structure 21 and the bobbin 5 on the rocker arm 2 are located on opposite sides of the connecting shaft 3, so that when the side of the rocker arm 2 that clamps the bobbin 5 is raised, one end of the rod-like structure 21 swings downward. At least one sliding hole 22 is provided on the rod-like structure 21, and the limiting rod 42 is slidably disposed in one of the sliding holes 22. In this example, two sliding holes 22 are provided on the rod-like structure 21, and the positions of the two sliding holes 22 correspond to the two sliding grooves 412 on the limiting plate 41, respectively. The limiting rod 42 is provided with a position-adjustable limiting plate 422; the limiting plate 422 is located on the side of the rod-shaped structure 21 near the limiting disk 41; a first elastic element 421 is provided between the limiting plate 422 and the rod-shaped structure 21. In this example, the first elastic element 421 is a spring. The spring cooperates with the limiting plate 422 to control the rod-shaped structure 21 to always maintain contact with the limiting disk 41.

[0030] The end of the limiting rod 42 near the limiting plate 41 is rounded; the sliding groove 412 on the limiting plate 41 is an arc-shaped groove that mates with the rounded end of the limiting rod 42, allowing the rounded end of the limiting rod 42 to slide in both directions within the arc-shaped groove; a limiting hole 411 is provided at or near the bottom of the arc-shaped groove, so that when the rocker arm 2 swings upward to a higher position, the limiting rod 42 can be inserted into the limiting hole 411 at the bottom of the arc-shaped groove. A spherical handle 423 is provided at the end of the limiting rod 42 away from the limiting plate 41 for easy gripping and to prevent the limiting rod 42 from passing through the sliding hole 22 of the rod-shaped structure 21.

[0031] The rocker arm 2 includes an L-shaped fixed arm 23 and a long strip-shaped rotating arm 24; the rotating arm 24 is rotatably mounted on one end of the fixed arm 23 via a rotating shaft; a coil 1 is rotatably mounted on the fixed arm 23, and a coil 1 is also mounted on the side of the rotating arm 24 opposite to the fixed arm 23; the two coils 1 are arranged facing each other; in this example, the rotating arm 24 and the fixed arm 23 form a U-shaped structure, and two coils 1 are correspondingly mounted on the inward-facing side of the rotating arm 24 and the fixed arm 23.

[0032] A second elastic element 25 is provided between the rotating arm 24 and the fixed arm 23 to pull the rotating arm 24 toward the fixed arm 23. When the rotating arm 24 is rotated away from the fixed arm 23, the spool 5 clamped between the rotating arm 24 and the fixed arm 23 can be removed. In addition, when the spool 5 is clamped between the rotating arm 24 and the fixed arm 23, the second elastic element 25 can keep the rotating arm 24 and the fixed arm 23 clamping the spool 5, and provide a certain clamping pressure on both ends of the spool 5.

[0033] The rotating arm 24 is also provided with a support rod 26 for abutting against the fixed arm 23. The support rod 26 is located on the side of the rotating arm 24 closer to the fixed arm 23, so that when the yarn bobbin is not clamped between the rotating arm 24 and the fixed arm 23, there is a minimum rotation angle between the rotating arm 24 and the fixed arm 23, preventing the rotating arm 24 from rotating excessively and colliding with the fixed arm 23. In this example, the support rod 26 is generally arc-shaped, and a hollow groove is provided inside the support rod 26. A spring, which serves as a second elastic element 25, is provided in the hollow groove. One end of the spring is connected to the support rod 26, and the other end is connected to the fixed arm 23.

[0034] The connecting shaft 3 is also provided with a positioning component 31 for limiting the position of the rocker arm 2; in this example, the fixed arm 23 of the rocker arm 2 is provided with two rotating components for rotating connection with the connecting shaft 3. The positioning component 31 is located on both sides of the rotating component, which restricts the rotating component within a certain space and prevents the rocker arm 2 from sliding left and right on the rotating shaft.

[0035] During implementation, by setting a limiting plate 41 in conjunction with a limiting rod 42 on the rocker arm 2, the rocker arm 2 can be fixed by inserting the limiting rod 42 into the limiting hole 411 on the limiting plate 41 after rotating to a set angle. The stable mechanical connection structure ensures the safety of personnel operation. By setting the slide groove 412 as an arc-shaped groove, in conjunction with the round head at the end of the limiting rod 42, the limiting rod 42 can slide smoothly in the slide groove 412. With the limiting hole 411 set in the slide groove 412, the rocker arm 2 is fixed at different heights. By setting a second elastic element 25, the rotating arm 24 and the fixed arm 23 can keep clamping the wire drum 5. With the support rod 26, the minimum rotation angle of the rotating arm 24 is limited to prevent it from colliding with the fixed arm 23.

[0036] The above description is merely a specific example of this utility model and does not constitute any limitation on this utility model. Obviously, those skilled in the art, after understanding the content and principle of this utility model, may make various modifications and changes in form and details without departing from the principle and structure of this utility model. However, these modifications and changes based on the concept of this utility model are still within the protection scope of the claims of this utility model.
