DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0019] Refer to Figures 1 to 3A wire-swinging roller arrangement structure as shown includes a frame, a mounting seat 20, a first roller 31 and a second roller 32. The frame includes at least one cross bar 11 and a plurality of vertical bars 12 arranged at intervals on the cross bar 11. The cross bar 11 and / or the vertical bar 12 can be fixedly connected to the machine frame through a bolt structure, a snap structure, etc. There are several mounting seats 20 and they are correspondingly arranged on each vertical bar 12. Mounting holes are respectively provided on two opposite sides of the mounting seat 20. The first roller 31 and the second roller 32 are correspondingly mounted on the two mounting holes, and the first roller 31 and the second roller 32 on the adjacent vertical bar 12 are arranged in a staggered manner, so that the distance between two adjacent vertical bars 12 can be set smaller, and thus more first rollers 31 / second rollers 32 can be arranged without changing the overall size of the frame. To ensure the consistency of the product, the rotation axes of the first roller 31 and the second roller 32 are parallel to each other, so that the wire bundle conveying direction of each production line is the same.

[0020] In some possible embodiments, the first roller 31 is sleeved on a first mounting shaft 311. The first mounting shaft 311 can be in the shape of a straight rod. The second roller 32 is sleeved on a second mounting shaft 321. The longitudinal section of the second mounting shaft 321 is circular and the cross section is in the shape of "Π". Specifically, the second mounting shaft 321 includes a first connecting rod 3211 and a third connecting rod 3213 that are parallel to each other. One end of the first connecting rod 3211 is inserted into the mounting hole, one end of the third connecting rod 3213 is sleeved with the second roller 32, and the other ends of the first connecting rod 3211 and the third connecting rod 3213 are connected by a second connecting rod 3212. It can be seen that the rotation axis of the first roller 31 coincides with the axis of the first mounting shaft 311 and passes through the axis of the mounting hole, and the rotation axis center of the second roller 32 does not pass through the axis of the mounting hole. Therefore, when installing, the second roller 32 can be rotated to a position where it is staggered with the first roller 31 and does not interfere with each other, so that the distance between two adjacent vertical bars 12 can be reduced, and more vertical bars 12 can be arranged when the outer dimension of the frame is certain, and thus more first rollers 31 / second rollers 32 can be arranged.

[0021] In some possible embodiments, the second mounting shaft 321 is integrally formed, and the second connecting rod 3212 is perpendicular to the first connecting rod 3211 / third connecting rod 3213. Specifically, the second mounting shaft 321 can be obtained by bending a straight rod twice, or the first connecting rod 3211, the second connecting rod 3212 and the third connecting rod 3213 can be welded and fixed in sequence. After installation, the first connecting rod 3211 is located outside the second roller 32.

[0022] In some possible embodiments, the mounting hole is a spline hole. Splines are provided at one end of the first mounting shaft 311 and the first connecting rod 3211, which are adapted to the spline hole. Since the wire bundle conveying does not generate an axial force on the first roller 31 / the second roller 32, the first mounting shaft 311 and the first connecting rod 3211 can be respectively inserted and fixed in the mounting hole. When installing, the angle at which the first connecting rod 3211 is inserted into the mounting hole determines the position of the second roller 32 on the vertical rod 12. Therefore, the spline fit not only facilitates the adjustment of the position of the second roller 32, but also can prevent the first connecting rod 3211 from rotating relative to the mounting base 20 during use, which may cause the second roller 32 to be displaced and interfere with the first roller 31.

[0023] In some possible embodiments, the axis line of the mounting hole intersects the axis line of the cross bar 11 in space, and the included angle range of the intersection is 10° to 30°. At this time, the plane where the axis lines of the first roller 31 and the second roller 32 are located forms a certain included angle with the plane where the cross bar 11 and the vertical rod 12 are located, and the included angle range is 10° to 30°. Such a design can further compress the distance between two adjacent vertical rods 12, making the arrangement structure of the wire laying rollers more compact.

[0024] In some possible embodiments, a plurality of threaded holes 13 are arranged vertically on the vertical rod 12, and through holes 21 are formed on the mounting base 20. The locking bolts pass through the through holes 21 and are fixedly connected to the threaded holes 13. During maintenance or replacement, the entire frame can be removed, and after replacing it with a new frame, the production line can resume production, reducing the downtime for maintenance and replacement. At this time, for the removed frame, the mounting base 20 where the wire laying roller to be replaced or maintained is located can be removed, and the two first rollers 31 / second rollers 32 on the mounting base 20 can be maintained or replaced separately, which is convenient and fast to operate.

[0025] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed by the present utility model should be covered by the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
