Spiral sleeves are usually formed by wrapping wire material around the wire core in a spiral shape, and the wire material can be stainless steel wire. The production rate of automatic wrapping and installation of general spiral sleeves on the wire core is relatively low, time-consuming, inefficient, and energy-intensive, which needs to be improved. Summary of the invention

[0017] In order to more fully understand the technical content of the present invention, the technical solution of the present invention is further introduced and illustrated in conjunction with specific embodiments below.

[0018] The device of this embodiment is used to wind a strip or ribbon material 42 around a wire core 41 to form a spiral sleeve. The wire core 41 can be an optical fiber bundle, and the material 42 can be a stainless steel wire. Figure 1As shown, the device includes a first rotating shaft 31, a second rotating shaft 32 and a rotating disk 30 that can rotate around its own central axis. The second rotating shaft 32 is used to drive the rotating disk 30 to rotate. Specifically, the rotation axis of the second rotating shaft 32 is colinear with the rotation axis of the rotating disk 30, the second rotating shaft 32 is driven by the motor 52 through a belt, and the second rotating shaft 32 is fixedly connected to the rotating disk 30, so that the angular velocity of the second rotating shaft 32 is equal to the angular velocity of the rotating disk 30. The second rotating shaft 32 is hollow, and the first rotating shaft 31 passes through the second rotating shaft 32. The first rotating shaft 31 and the second rotating shaft 32 can be isolated by a bearing (not shown) to reduce the friction between the two. The first rotating shaft 31 is driven by the motor 51 through a belt, and the rotation axis of the first rotating shaft 31 is also colinear with the rotation axis of the rotating disk 30, and the first rotating shaft 31 is also hollow. The wire core 41 to be processed passes through the first rotating shaft 31 and runs through the middle position of the rotating disk 30.

[0019] like Figure 1-3 As shown, the turntable 30 is provided with a first component 10 for winding the raw material 42 on the core 41 and a second component 20 for transferring the raw material 42 to the first component 10. The first component 10 is arranged in the middle of the turntable 30 and the core 41 passes through the middle of the first component 10, and the first component 10 rotates synchronously with the turntable 30. When the turntable 30 rotates, the first component 10 winds the raw material 42 on the core 41 along the route of the spiral line, and the raw material 42 gradually pushes the core 41 along the central axis of the turntable 30 when it is wound. Specifically, the first component 10 includes two ejectors 11 on a plane perpendicular to the central axis of the turntable 30. The ejectors 11 are distributed around the central axis of the turntable 30. In this embodiment, the two ejectors 11 form an angle of 95 degrees, and the feeding direction of the raw material 42 is opposite to the top of the angle of the two ejectors 11. The tips of the two ejectors 11 both point to the central axis of the turntable 30, and the core 41 passes through the position where the tips of all ejectors 11 point. The tip of the ejector pin 11 is generally made of a wear-resistant and high-strength metal. When the turntable 30 rotates, the wire core 41 does not rotate with the turntable 30 (i.e., the rotation speed is zero), and the raw material 42 sent from the second component 20 forms an acute angle greater than 45 degrees with the wire core 41. The raw material 42 is squeezed toward the wire core 41 by the tip of the ejector pin 11. Since all the ejector pins 11 rotate around the wire core 41 as the center, the raw material 42 is squeezed by the tip of the ejector pin 11 in turn, that is, the raw material 42 is wound around the wire core 41 along the spiral line by the tip of the ejector pin 11. At the same time, the wound raw material 42 will be squeezed with the raw material 42 wound in the previous circle, and then the wire core 41 will be gradually squeezed and pushed out along the central axis direction of the turntable 30, and finally a wrapped spiral sleeve is formed on the outer surface of the wire core 41.

[0020] like Figure 1-3As shown, the second assembly 20 is fixed on the turntable 30 and rotates synchronously with the turntable 30. The second assembly 20 includes a pair of rollers 21. The two rollers 21 of the pair of rollers 21 are close to each other and rotate in opposite directions. The raw material 42 is clamped by the pair of rollers 21 and transferred to the first assembly 10. The first rotating shaft 31 is used to drive the rollers 21 of the second assembly 20. Specifically, as shown in FIG. Figure 2 As shown, one end of the pressure roller 21 is provided with a gear 211 that meshes with each other. The first rotating shaft 31 drives the pair of pressure rollers 21 to rotate through a gear transmission mechanism, and the angular velocity of the first rotating shaft 31 is greater than the angular velocity of the turntable 30. The difference in angular velocity between the first rotating shaft 31 and the turntable 30 makes the pressure roller 21 itself rotate synchronously with the turntable 30, while the pressure roller 21 will also be driven by the first rotating shaft 31 to rotate. The angular velocity of the pressure roller 21 is converted into a linear velocity, which is the conveying speed of the raw material 42.

[0021] like Figure 2 As shown, the second assembly 20 further includes a coiling tray 22 for winding the raw material 42. The raw material 42 pulled out from the coiling tray 22 is connected to the pressing roller 21 of the second assembly 20. The coiling tray 22 is fixedly connected to the rotating disk 30 and rotates synchronously, and the center of the coiling tray 22 is colinear with the rotation axis of the rotating disk 30. Figure 2 As shown by the dotted line, the coil tray 22 can be disposed on either side of the turntable 30 .

[0022] In other embodiments, Figure 4 As shown, the turntable 30 can be driven to rotate directly by the motor 53 through a belt transmission mechanism, while the second rotating shaft is omitted.

[0023] In other embodiments, if space permits, more than two ejector pins may be provided.

[0024] In other embodiments, more than one pair of pressure rollers may be provided or a plurality of separate unpaired pressure rollers may be provided in addition to one pair of pressure rollers. Then, only one pair of pressure rollers needs to be selected to provide conveying thrust for the raw material, and the other pressure rollers may be used to adjust the direction or tension of the raw material.
