[0021] Cement pipes are important components indispensable in urban construction, generally used as water conveyance pipelines and underground cable pipelines. During the processing of cement pipes, in order to increase the rigidity of the cement pipes, woven steel wires (usually in the form of steel wire structures) need to be added to the concrete during casting. The steel wires are usually wound on a spool, and the steel wires pulled out from the spool are generally in a bent state. When the bent steel wires are woven into a steel reinforcement cage, local deformation will occur and welding is difficult. Therefore, it is necessary to first straighten the steel bars with a device and then carry out the weaving process. However, the existing wire winding devices have the following problems when in use: complex wire routing, unclear straightening effect, and poor compatibility. Therefore, the present utility model provides a wire winding device for a wire weaving machine, which is specifically described as follows.
[0022] As Figure 1As shown in the figure, the utility model provides a wire collecting device for a wire weaving machine, which includes a positioning mechanism, a first straightening mechanism 1, a second straightening mechanism 2, and a wire pulling jaw 3 arranged in sequence. The straightening directions of the first straightening mechanism 1 and the second straightening mechanism 2 form a preset included angle with each other; the positioning mechanism includes a first positioning wheel 41 and a second positioning wheel 42. The central axes of the first positioning wheel 41 and the second positioning wheel 42 are parallel to each other, and the radius R1 of the first positioning wheel 41, the radius R2 of the second positioning wheel 42, and the diameter L of the steel bar satisfy: (1 - 1.3)L = R1 + R2; the first straightening mechanism 1 includes at least two first limiting wheels 11 arranged in parallel and at least three second limiting wheels 12 arranged in parallel. The first limiting wheels 11 and the second limiting wheels 12 are arranged in a vertically staggered manner; the second straightening mechanism 2 includes a first limiting column 21, a second limiting column 22, and a connecting rod 23. The central axes of the first limiting column 21 and the second limiting column 22 are simultaneously sleeved with the connecting rod 23.
[0023] The wire collecting device for a wire weaving machine provided by the utility model is a machine for weaving steel bar meshes in cement pipelines in the field of mechanical processing. During weaving, the steel bars need to be straightened to ensure that the steel bar cages made by welding are more stable and prevent local deformation. The wire collecting device includes a positioning mechanism for initially positioning the steel bars, a first straightening mechanism 1 and a second straightening mechanism 2 that have been straightened twice, and a wire pulling jaw 3 for pulling the steel bars out of the positioning mechanism and the two straightening mechanisms. The central axes of the two positioning wheels in the positioning mechanism are parallel to each other, and the radius R1 of the first positioning wheel 41, the radius R2 of the second positioning wheel 42, and the diameter L of the steel bar satisfy: (1 - 1.3)L = R1 + R2, so that the steel bars are initially straightened while being positioned; then, the steel bars enter the first straightening mechanism 1. The first straightening mechanism 1 includes at least two first limiting wheels 11 arranged above or below and at least three second limiting wheels 12 arranged below or above. The upper and lower positioning wheels are arranged in a staggered manner, so that the bent parts of the steel bars are straightened when passing through multiple limiting wheels; when entering the second straightening mechanism 2, the straightening direction of the second straightening mechanism 2 is opposite to or forms a certain included angle with the straightening direction of the first straightening mechanism 1, so that the steel bars that are not straightened in the straightening direction of the first straightening mechanism 1 continue to be straightened in another direction. Finally, the steel bars are pulled out and sent to the wire weaving machine. The utility model makes the steel bars entering the wire weaving machine in a straight state, realizes an obvious straightening effect with a simple mechanical structure. In addition, it is possible to directly adjust the spacing between the positioning wheels and the limiting wheels in the straightening mechanism and the positioning mechanism to be compatible with steel bars of various specifications, which improves the compatibility of the wire collecting device.
[0024] As described above, the radius R1 of the first positioning wheel 41, the radius R2 of the second positioning wheel 42, and the diameter L of the steel bar satisfy: (1 - 1.3)L = R1 + R2. When L = R1 + R2, that is, when the steel bar is just clamped between the first positioning wheel 41 and the second positioning wheel 42, it just plays the role of positioning the steel bar; when 1.2L or 1.3L is equal to R1 + R2, not only can the steel bar be positioned, but also the slightly bent steel bar can be straightened. Specifically, the distance between the first positioning wheel 41 and the second positioning wheel 42 can be adjusted according to the bending condition of the steel bar.
[0025] In some embodiments, it further includes a limit wheel correction pin 5. The limit wheel correction pin 5 passes through the fixing plate and is arranged to abut against the shaft of the first limit wheel 11 or the second limit wheel 12. The correction pin can adjust the position of one or both of the limit wheels, and then change the distance between the first limit wheel 11 and the second limit wheel 12, facilitating compatibility with steel bars of different specifications.
[0026] In some embodiments, the foregoing connecting rod 23 includes at least one waist-shaped hole, and the waist-shaped hole is sleeved with the center axis of the second limit post 22 or the second limit post 22. The waist-shaped hole can adjust the relative position between the connecting rod 23 and the first limit post 21 or the second limit post 22, indirectly adjust the relative distance between the first limit post 21 and the second limit post 22, and then improve the compatibility with steel bars of different specifications.
[0027] In some embodiments, it further includes a limiting mechanism, and the limiting mechanism is arranged between the second straightening mechanism 2 and the first straightening mechanism 1. The limiting mechanism can adjust the position of the steel bar entering the second straightening mechanism 2 to prevent the movement route of the steel bar from deviating after coming out of the first straightening mechanism 1 and being unable to enter the second straightening mechanism 2. Among them, the limiting mechanism includes a limiting clamp or two relatively arranged limiting shafts. Both the limiting clamp or the two relatively arranged limiting shafts can play a limiting role, and specific selection can be made according to actual adaptability, and this embodiment does not make specific limitations on this.
[0028] In addition, it may further include a cutting mechanism. The cutting mechanism is close to the second straightening mechanism 2, and the wire-pulling jaw 3 is docked with the cutting mechanism. The steel bar after being straightened and pulled out is cut by the cutting mechanism, which facilitates directly pulling out the steel bar from the wire-receiving device. The structure of the cutting mechanism is not specifically limited in this embodiment, and the corresponding existing mechanism can be referred to to cut the steel bar.
[0029] In some embodiments, it further includes a guide wheel and a guide wheel bracket, and the guide wheel is arranged close to the positioning mechanism. In this embodiment, the guide wheel plays a role in transmitting the steel bar to be straightened. The size of the guide wheel needs to satisfy that at least half of the steel bar is wrapped inside the wheel edge of the guide wheel to prevent the steel bar from falling during the transmission process.
[0030] Finally, a wire collecting device of a wire weaving machine according to the present utility model includes a positioning mechanism, a first straightening mechanism 1, a second straightening mechanism 2, and a wire pulling jaw 3 arranged in sequence. The straightening directions of the first straightening mechanism 1 and the second straightening mechanism 2 form a preset included angle with each other; the positioning mechanism includes: a first positioning wheel 41 and a second positioning wheel 42. The central axes of the first positioning wheel 41 and the second positioning wheel 42 are parallel to each other, and the radius R1 of the first positioning wheel 41, the radius R2 of the second positioning wheel 42, and the diameter L of the steel bar satisfy: (1 - 1.3)L = R1 + R2; wherein, the first straightening mechanism 1 includes: at least two first limiting wheels 11 arranged in parallel, and at least three second limiting wheels 12 arranged in parallel. The first limiting wheels 11 and the second limiting wheels 12 are arranged in a vertically staggered manner; the second straightening mechanism 2 includes: a first limiting column 21, a second limiting column 22, and a connecting rod 23. The central axes of the first limiting column 21 and the second limiting column 22 are simultaneously sleeved with the connecting rod 23. The present utility model optimizes the structure of the existing wire collecting device, improves the straightening effect of the wire collecting device, and improves its compatibility at the same time.
