Description

Technical Field

[0001] This application relates to the technical field of winding machines, and more specifically, to a winding machine. Background Technology

[0002] With the rapid development of industries such as electronics, communications, and power, the usage of cables is constantly increasing. As an important piece of equipment in the cable production process, the performance and efficiency of cable winding machines directly affect the production quality and subsequent use of cables. However, existing cable winding machines have many problems in practical use, especially in terms of winding uniformity.

[0003] In existing cable winding machines, cables are often not wound evenly on the spool during the winding process. The cable may concentrate in the middle of the spool, resulting in less cable at both ends and excessive cable accumulation in the middle. This uneven winding method not only affects the appearance of the cable but may also lead to problems such as loosening and tangling during subsequent use. Utility Model Content

[0004] This application provides a cable winding machine to solve the problem that cable winding machines in the prior art are prone to loosening when winding cables.

[0005] A winding machine according to this application includes: a frame assembly; a winding spool assembly rotatably mounted on the frame assembly; a guide shaft assembly including a guide shaft structure rotatably mounted on the frame assembly, the winding spool assembly being connected to the guide shaft structure; and a guide wire assembly including a guide wire structure and a movable guide structure, the movable guide structure being mounted on the guide wire structure, the guide shaft structure cooperating with the movable guide structure to drive the guide wire structure to reciprocate along the axial direction of the guide shaft structure, the cable passing through the guide wire structure and connected to the winding spool assembly.

[0006] Furthermore, the guide wire structure includes a wire box with a wire passage hole on the front wall of the wire box, the movable guide structure includes a guide plate rotatably mounted on the top wall of the wire box, and the guide shaft structure includes a guide shaft and a spiral guide slide disposed on the guide shaft. The spiral guide slide includes a first spiral guide slide and a second spiral guide slide, the first spiral guide slide and the second spiral guide slide having opposite directions of rotation, and the guide plate being at least partially located within the spiral guide slide of the guide shaft structure.

[0007] Furthermore, the guide plate includes a mounting rod and a guide plate. The mounting rod is rotatably mounted on the top wall of the wire box, the upper end of the guide plate is connected to the lower end of the mounting rod, and the lower end of the guide plate is located in the spiral guide slide.

[0008] Furthermore, the intersection of the first spiral guide slide and the second spiral guide slide is a cross section, which is a groove. The length of the cross section is between 1 / 8 and 1 / 6 of the guide shaft diameter, and the width of the guide plate is greater than the length of the cross section.

[0009] Furthermore, the end sections on both sides of the guide plate are arc-shaped.

[0010] Furthermore, the guide wire structure also includes a first roller and a second roller, which are rotatably mounted on the wire box. A wire passage is provided between the first roller and the second roller, and wire holes are provided corresponding to the wire passage.

[0011] Furthermore, the guide wire structure also includes a guide rod, the lower part of the wire box has a guide hole, the guide rod is mounted on the frame assembly, and the guide rod passes through the guide hole.

[0012] Furthermore, the spool assembly includes a drive motor and a spool structure. The drive motor is fixed on the frame assembly, and the spool structure is rotatably mounted on the frame assembly. The output end of the drive motor is connected to the spool structure.

[0013] Furthermore, the winding bobbin assembly also includes a drive pulley and a drive belt, and the guide shaft structure also includes a driven pulley, with the drive belt sleeved on the circumferential outer side of the drive pulley and the driven pulley.

[0014] Furthermore, the frame assembly includes a back plate, a first side plate, and a second side plate. The back plate is located between the first side plate and the second side plate. The drive motor is located on the side of the first side plate away from the second side plate. Both ends of the guide shaft structure and both ends of the guide wire structure are rotatably mounted on the first side plate and the second side plate. The moving guide structure and the winding shaft structure are both located between the first side plate and the second side plate.

[0015] Applying the technical solution of this application, the cable passes through the guide wire structure and connects to the winding spool assembly. As the winding spool assembly rotates, the cable winds around it. The guide shaft assembly and the moving guide structure cooperate to cause the guide wire structure to reciprocate along the axial direction of the guide shaft. Consequently, the cable moves regularly along the guide shaft assembly, resulting in a systematic winding around the winding spool assembly. The technical solution of this application effectively solves the problem of loosening during cable winding in existing winding machines. Attached Figure Description

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.

[0029] like Figures 1 to 5 As shown, the winding machine of this embodiment includes: a frame assembly 10, a winding spool assembly 20, a guide shaft assembly 30, and a guide wire assembly 40. The winding spool assembly 20 is rotatably mounted on the frame assembly 10. The guide shaft assembly 30 is rotatably mounted on the frame assembly 10, and the winding spool assembly 20 is connected to the guide shaft assembly 30. The guide wire assembly 40 includes a guide wire structure 41 and a movable guide structure 42. The movable guide structure 42 is mounted on the guide wire structure 41. The guide shaft assembly 30 cooperates with the movable guide structure 42 to drive the guide wire structure 41 to reciprocate along the axial direction of the guide shaft assembly 30. The cable passes through the guide wire structure 41 and connects to the winding spool assembly 20.

[0030] Applying the technical solution of this embodiment, the cable passes through the guide wire structure 41 and connects to the winding spool assembly 20. As the winding spool assembly 20 rotates, the cable winds around it. The guide shaft assembly 30 and the movable guide structure 42 cooperate to cause the guide wire structure 41 to reciprocate along the axial direction of the guide shaft 31. Consequently, the cable moves regularly along the guide shaft 31 via the guide shaft assembly 30, resulting in the cable being wound systematically around the winding spool assembly 20. The technical solution of this embodiment effectively solves the problem of loosening during cable winding in existing winding machines.

[0031] It should be noted that the aforementioned frame assembly 10 can be one or two. For example, the spool assembly 20 is mounted on one frame assembly 10, and the guide shaft assembly 30 is mounted on another frame assembly 10. This embodiment uses one frame assembly 10. The side of the spool assembly 20 has a cable end holder. The end of the cable is inserted into the root of the side plate of the spool structure 22. After the operator holds this end (or clamps it with a clip) and rotates the spool structure 22 several times (usually four or five times), the cable is initially fixed under the combined action of its own restoring force and the side wall of the spool structure 22.

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the guide wire structure 41 includes a wire box 411 with a wire through hole 412 on its front wall. The movable guide structure 42 includes a guide plate 421 rotatably mounted on the top wall of the wire box 411. The guide shaft assembly 30 includes a guide shaft 31 and a spiral guide slide 32 disposed on the guide shaft 31. The spiral guide slide 32 includes a first spiral guide slide and a second spiral guide slide, with opposite rotation directions. The guide plate 421 is at least partially located within the spiral guide slide 32 of the guide shaft assembly 30. This structure is simple to manufacture, easy to assemble and disassemble, and easy to operate. A force is applied to the guide plate 421 by the spiral guide slide 32, and the guide plate transmits this force to the wire box 411, causing the wire box 411 to reciprocate regularly along the axial direction of the guide shaft 31. It should be noted that in this embodiment, the first and second spiral guide slides are only opposite in spiral direction; all other aspects are the same, such as pitch and depth. In this embodiment, the spiral guide slide 32 is a spiral guide groove. As another possible implementation, the spiral guide slide 32 is a spiral guide protrusion, and the bottom of the guide piece 421 has a groove that mates with the guide protrusion, which will not be described in detail here.

[0033] like Figure 5 As shown, in this embodiment, the guide plate 421 includes a mounting rod and a guide plate. The mounting rod is rotatably mounted on the top wall of the wire box 411. The upper end of the guide plate is connected to the lower end of the mounting rod, and the lower end of the guide plate is located within the spiral guide slide 32. The above structure has low processing and installation costs and is easy to operate. The mounting rod has a circular cross-section, which facilitates the rotation of the mounting rod and the wire box 411, such as when the guide plate 421 changes between the first and second spiral guide slides.

[0034] It should be noted that the endpoints of the first and second helical guide slides are connected, and the connecting arcs at these points use a relatively large diameter central angle. This ensures smoother rotation of the guide plate when it turns from one helical direction to another. The diameter of the aforementioned relatively large diameter central angle is 3 to 8 times the pitch of the helical guide slide 32.

[0035] like Figure 5 As shown in the technical solution of this embodiment, the intersection of the first and second spiral guide slides is called an intersection segment, which is a groove. The length of the intersection segment is between 1 / 8 and 1 / 6 of the diameter of the guide shaft 31, and the width of the guide plate is greater than the length of the intersection segment. This structure effectively ensures that when the guide plate moves in the middle of the first or second spiral guide slide, it is not easy for the guide plate to slip into the other spiral guide slide. For example, when the guide plate moves in the first spiral guide slide, its tilt direction is tangent to the inner wall of the first spiral guide slide. When the front end of the guide plate enters the intersection segment, the rear end of the guide plate still engages with the first spiral guide slide, thus maintaining the same direction as the first spiral guide slide and preventing it from easily entering the second spiral guide slide. When the front end of the guide plate enters the end of the first spiral guide slide, the first and second spiral guide slides are connected by an arc, allowing the guide plate to smoothly enter the second spiral guide slide.

[0036] like Figure 6 As shown in the technical solution of this embodiment, the end sections of both sides of the guide plate are arc-shaped. The above structure avoids the guide plate getting stuck or the difficulty in changing the spiral guide slide when changing the spiral guide slide, that is, the arc-shaped guiding effect is smoother.

[0037] like Figure 5As shown, in this embodiment, the guide wire structure 41 further includes a first roller 413 and a second roller 414. The first roller 413 and the second roller 414 are rotatably mounted on the wire box 411, and a wire passage 100 is provided between the first roller 413 and the second roller 414. A wire passage hole 412 is correspondingly provided with the wire passage channel 100. The arrangement of the first roller 413 and the second roller 414 makes the movement of the cable more stable and less prone to misalignment. It should be noted that the diameter of the wire passage hole 412 in this embodiment is slightly larger than the diameter of the cable, and a rubber ring is provided around the wire passage hole. The diameter of the rubber ring is slightly smaller than the diameter of the cable. Through the deformation of the rubber ring and its cooperation with the cable, most of the mud and sand on the cable are scraped off the outside of the wire box 411 when the cable is retracted. The first roller 413 (or roller shaft) is located at the bottom. The middle part of the first roller 413 has a constricted section, and the middle part of the second roller 414 has a convex diameter section. The convex diameter section and the constricted diameter section are arranged to form a wire passage 100. The length of the convex diameter section is greater than the length of the constricted section. After the cable passes through the wire passage hole 412, it enters the wire passage 100.

[0038] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the guide wire structure 41 further includes a guide rod 415. The lower part of the wire box 411 has a guide hole 416. The guide rod 415 is mounted on the frame assembly 10 and passes through the guide hole 416. The cooperation between the guide rod 415 and the guide hole 416 makes the movement of the wire box 411 more stable. It should be noted that the cross-section of the guide rod can be circular or rectangular, as long as the wire box 411 moves along the axial direction of the guide rod.

[0039] like Figure 1 and Figure 2 As shown in the technical solution of this embodiment, the spool assembly 20 includes a drive motor 21 and a spool structure 22. The drive motor 21 is fixed on the frame assembly 10, and the spool structure 22 is rotatably mounted on the frame assembly 10. The output end of the drive motor 21 is connected to the spool structure 22. Driven by the drive motor 21, the labor intensity is greatly reduced, eliminating the need for manual rotation of the spool structure 22. It should be noted that the drive motor 21 can be a forward / reverse motor, and the drive motor 21 and the spool structure 22 are connected via a reducer. Without the drive motor 21, the operator would need to manually rotate the spool structure 22.

[0040] like Figure 2As shown, in this embodiment, the winding spool assembly 20 further includes a drive pulley 23 and a transmission belt 24, and the guide shaft assembly 30 further includes a driven pulley 33. The transmission belt 24 is sleeved on the circumferential outer side of the drive pulley 23 and the driven pulley 33. The transmission belt 24 causes the drive pulley 23 to drive the driven pulley 33 to rotate, effectively ensuring the synchronization of the winding spool structure 22 and the guide shaft assembly 30. It should be noted that the winding machine of this application works best when the cable is short. When the cable is long, due to the winding of the cable, the winding diameter of the winding spool structure 22 becomes increasingly thick, and sometimes the winding order may become misaligned. In this case, the operator only needs to manually remove the overlapping cable in the middle, and the winding machine of this application greatly reduces labor intensity.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, the rack assembly 10 includes a back plate, a first side plate, and a second side plate. The back plate is located between the first and second side plates. The drive motor 21 is located on the side of the first side plate away from the second side plate. Both ends of the guide shaft assembly 30 and both ends of the guide wire structure 41 are rotatably mounted on the first and second side plates. The moving guide structure 42 and the winding shaft structure 22 are both located between the first and second side plates. This structure is compact, uses less material, saves cost, and is lightweight. It should be noted that the rack assembly 10 also includes a bottom plate, located at the bottom of the back plate, the first side plate, and the second side plate, making the rack assembly 10 more stable.
