[0032] See also Figure 4 The loading tray assembly 100 includes a fixing portion 110, a bearing 120 mounted on the fixing portion 110, a tray 130 connected to the bearing 120, and a plurality of positioning posts 140 fixed to the tray 130. The plurality of positioning posts 140 are evenly distributed along the circumference of the tray 130. When specifically arranged, the number of positioning posts 140 can be set as required. In this embodiment, four positioning posts 140 are arranged at intervals of 90 degrees. In other embodiments, three positioning posts 140 can also be arranged at intervals of 120 degrees.

[0033] See also Figure 4 and Figure 5 The hoisting assembly 200 includes a winding body 210 for winding the iron wire, a hoisting part 220 fixed to the top of the winding body 210, and a plurality of limiting parts 230 fixed to the bottom of the winding body 210. The winding body 210 is placed on the tray 130, and the limiting part 230 cooperates with the positioning column 140 to prevent the winding body 210 from detaching from the tray 130; the feeding assembly 300 includes two counter-rotating feeding wheels, the two feeding wheels clamp the iron wire 10 and rotate in the opposite direction to pull the iron wire 10 through between the two feeding wheels; the straightening assembly 400 includes a rotatably arranged rotating box 410, and a plurality of groups of straightening block groups 420 are fixedly connected in the cavity of the rotating box 410, each group of straightening block groups 420 includes two straightening blocks 421 arranged on both sides of the central axis of the rotating box 410, and a straightening channel for the iron wire to pass through is reserved between the two straightening blocks 421, and the rotating box 410 drives the plurality of groups of straightening block groups 420 to rotate around the central axis.

[0034] It should be noted that one of the purposes of providing the mutually cooperating limiting portion 230 and the positioning column 140 is to facilitate the placement of the lifting assembly 200 at the center position of the loading tray assembly 100, that is, to play a positioning function, and another purpose is to prevent the lifting assembly 200 from being separated from the loading tray assembly 100 during the rotation process, that is, to play a limiting role, thereby further improving the safety of the device.

[0035] See also Figure 6 and Figure 7During the working process, the iron wire 10 is wound on the winding body 210 and carried on multiple limiting parts 230 at the bottom. After the iron wire is collected, the lifting device is used to lift the lifting part 220 at the top of the winding body 210 and move it toward the upper material tray assembly 100. When it is moved to the working area for placement, the multiple limiting parts 230 at the bottom of the winding body 210 and the multiple positioning columns 140 on the tray 130 are used for one-to-one positioning. The positioning columns 140 are inserted into the limiting parts 230, and the lifting assembly 200 is placed on the tray 130 of the loading tray assembly 100. One end of the wire 10 is extended into and clamped between two counter-rotating feeding wheels. The two feeding wheels clamp the wire 10 and rotate in the opposite direction to pull the wire 10 through between the two feeding wheels. The tray 130 rotates to continuously discharge the material, and the wire enters the straightening assembly 400, and drives several groups of straightening block groups 420 to rotate around the central axis through the rotating box 410 to straighten the wire.

[0036] See also Figure 4 and Figure 5 The high-speed straightening machine uses a loading tray assembly 100 and a hoisting assembly 200 to prepare and load materials, uses a feeding assembly 300 to automatically pull the wire 10 into the straightening assembly 400, and uses the straightening assembly 400 to straighten the wire, thereby improving work efficiency.

[0037] See also Figure 2 In one embodiment, a supporting block 430 is correspondingly arranged in front of each straightening block group 420. The supporting block 430 is fixedly connected to the rotating box 410 by bolts, and a central hole is formed in the middle of the supporting block 430 for the iron wire to pass through.

[0038] In the present embodiment, there are three groups of straightening block groups 420, and the straightening blocks 421 are rectangular blocks. Each straightening block 421 is fixedly connected to the rotating box 410 by bolts. The straightening channel formed by each group of straightening blocks 421 coincides with the central axis of the rotating box 410 or is tilted. The tilt angle of the supporting block 430 corresponding to each group of straightening block groups is the same as the tilt angle of the straightening block group. The tilted straightening block group 420 and the supporting block 430 will reduce the space through which the wire 10 passes through the angle portion during the rotation process, thereby straightening, i.e., straightening the wire. Different straightening block groups 420 have different tilting directions. The rotating box 410 is driven to rotate by a pulley set at one end. The specific driving method is not limited. In the present embodiment, the motor is transmitted to the pulley, and the pulley drives the rotating box 410 to rotate, and the straightening block group 420 and the supporting block 430 inside the rotating box 410 rotate accordingly.

[0039] See also Figure 6 and Figure 7In one embodiment, the winding body 210 includes a bottom ring 211 and four longitudinal reinforcing bars 212 fixed to the bottom ring 211. The iron wire 10 is wound around the periphery of the four longitudinal reinforcing bars 212, and after continuous winding, the iron wire 10 is carried on the limiting portion 230 fixed to the bottom ring 211.

[0040] In one embodiment, a lifting tie rod 221 is fixed between two diagonal longitudinal tie rods 212, and two lifting tie rods 221 are arranged between four longitudinal tie rods 212 to form a cross-shaped lifting portion 220. This arrangement facilitates the use of a crane to lift the entire lifting assembly 200 with the wire wrapped around it and place it on the loading tray assembly 100.

[0041] See also Figure 7 and Figure 8 In one embodiment, the lifting assembly 200 also includes a first limiting ring 240 and a second limiting ring 250. When the wire is wound around the outer periphery of the winding body 210 to form a wire roll 20, the first limiting ring 240 and the second limiting ring 250 are placed vertically on the upper part of the wire roll 20 to limit the wire roll 20.

[0042] Furthermore, in one embodiment, a counterweight rod 260 is press-fitted onto the upper portions of the first limiting ring 240 and the second limiting ring 250 .

[0043] The high-speed straightening machine is provided with a first limiting ring 240, a second limiting ring 250, and a counterweight rod 260 to limit the wire roll 20, so as to prevent the wire 10 from detaching from the winding body 210 from above during the straightening and feeding process, thereby reducing the possibility of safety accidents.

[0044] In one embodiment, the limiting portion 230 includes hanging rings 231 fixed to the bottom ring 211 , and each hanging ring 231 is used to hang the positioning column 140 and support the wire.

[0045] In one embodiment, the loading tray assembly 100 also includes a connecting chain 150, one end of the connecting chain 150 is detachably fixed to the limiting portion 230, and the other end of the connecting chain 150 is detachably fixed to the counterweight block 160, and the counterweight block 160 generates friction with the ground to provide resistance to reduce the rotation speed of the tray 130.

[0046] In one embodiment, the counterweight block 160 includes various specifications, and the resistance can be adjusted by replacing counterweight blocks of different specifications.

[0047] It should be noted that if the traction force of the feeding assembly 300 is too large, the tray 130 will rotate too fast and the wire 10 will be pulled out too fast. A connecting chain 150 is set on the limiting portion 230, and a counterweight block 160 is installed. The counterweight block 160 is replaceable and generates friction with the ground to provide resistance to reduce the rotation speed of the tray 130. This can prevent the tray 130 from rotating too fast and make the rotation speed of the tray 130 controllable to a certain extent, further improving the safety of the device.

[0048] In one embodiment, the feeding assembly 300 includes a bracket 310, an active feeding wheel 320 rotatably connected to the bracket 310, a driving member 330 connected to the active feeding wheel 320, a driving gear 340 coaxially connected to the active feeding wheel 320, a passive gear 350 meshed with the active gear 340, and a passive feeding wheel 360 coaxially connected to the passive gear 350. In a specific configuration, the driving member 330 may be a belt transmission mechanism, which utilizes a belt pulley to drive the active feeding wheel 320 to rotate, the active gear 340 coaxially connected to the active feeding wheel 320 rotates, the active gear 340 meshes with the passive gear 350 to drive the passive feeding wheel 360 to rotate in the opposite direction, and the two feeding wheels clamp the iron wire 10 and rotate in the opposite direction to pull the iron wire 10 through between the two feeding wheels.

[0049] It should be noted that see Fig. 9 In order to facilitate the end of the wire 10 to extend between the two feeding wheels, in some embodiments, the upper active feeding wheel 320 can be adjusted in height, and two adjusting bolts 370 are provided on the bracket 310. Threaded sleeves 380 connected to the adjusting bolts 370 are respectively provided on both sides of the rotating shaft of the active feeding wheel 320. The ends of the adjusting bolts 370 are fixed with a rotating handle 390. The rotating handle 390 drives the feeding wheel 320 to approach or move away from the passive feeding wheel 360 under the cooperation of the adjusting bolts 370 and the threaded sleeves 380. The distance between the active feeding wheel 320 and the passive gear 350 is adjusted by using structures such as adjusting bolts. The specific setting method can be set according to the conventional setting method in the field, which will not be repeated here.
