[0054] Working principle and workflow:

[0055] When in use, the device is moved as a whole to the construction site through the universal wheel 5; first, the steel bar cutting length is determined according to the requirements of the architectural design drawings, and the fixed-length threaded rod 75 is screwed to adjust the distance between the sliding frame 91 engaged therewith and the first V-shaped seat 87, the sliding frame 91 slides on the sliding rod 74, and the indicating block 93 slides on the scale 73, and the sliding frame 91 is adjusted until the indicating block 93 slides to the required value on the scale 73; then the first rotating plate 105 is rotated to make the fixing stud 110 disengage from the restriction of the fixing screw hole 109. During this process, the sliding plate 103 slides outward in the first movable plate 101. When the fixing stud 110 is completely disengaged from the fixing screw hole 109, the flip plate 104 is rotated outward to open, and then the steel bar roll is put on the outside of the supporting plate 114 and the steel bar roll is pushed until one end of the steel bar roll is supported on the second rotating plate 106. At this time, the driving motor 116 is started, and the driving motor 116 drives the rotating ring 113 to rotate. 113 is meshed with the adjusting thread 108, and the rotating ring 113 moves toward the fixed ring 111 on the central pillar 107, thereby driving the movable ring 112 to move toward the fixed ring 111, thereby causing one end of the connecting strut 115 on the movable ring 112 to move toward the fixed ring 111, and the other end of the connecting strut 115 pushes the supporting plate 114 to move outward, thereby driving the connecting strut 115 between the fixed ring 111 and the supporting plate 114 to rotate relatively, until the supporting plates evenly distributed on the circumference are 114 props up the steel coil on the inner side of the steel coil, then lifts the flip plate 104, rotates the first rotating plate 105, makes the fixing stud 110 engage with the fixing screw hole 109, and slides the sliding plate 103 into the first movable plate 101, thereby fixing the steel coil, so that the first rotating plate 105, the second rotating plate 106, the steel coil and the central pillar 107 form a unified whole, and the steel coil can rotate between the fixed plate 102 and the flip plate 104, which is convenient for unloading the steel coil.

[0056] After the rebar coil is fixed by the adaptive adjustment feeding assembly 1, the first pressing wheel 236 and the second pressing wheel 246 are lifted up respectively by the first telescopic column 234 and the second telescopic column 244, and at the same time, the first extrusion pad 86 and the second extrusion pad 95 are lifted up respectively by the first electric pressure rod 81 and the second electric pressure rod 94, and one end of the rebar is pulled out, and passes through the transition cylinder 222, the extrusion cylinder 223, the first conveying wheel 233, the detection cylinder 32, the cleaning cylinder 33 and the second conveying wheel 243 in sequence, and then the first pressing wheel 236 and the second pressing wheel 246 are pressed down by the first telescopic column 234 and the second telescopic column 244 respectively. At this time, the rebar is between the first conveying wheel 233 and the first pressing wheel 236 and between the second conveying wheel 243 and the second pressing wheel 246. The rubber gasket 26 sleeved on the first conveying wheel 233, the first pressing wheel 236, the second conveying wheel 243 and the second pressing wheel 246 squeezes the rebar and provides greater friction resistance, so that the first conveying wheel 233 and the second conveying wheel 243 can convey the rebar;

[0057] When the steel bar is pulled through the transition tube 222 and the extrusion tube 223, the resistance rubber ring 224 and the extrusion steel ball 225 respectively hinder and squeeze the steel bar, and the friction force and the extrusion force provide reverse pulling force to straighten the pulled steel bar for the first time; the first conveying motor 237 and the second conveying motor 247 respectively drive the first conveying wheel 233 and the second conveying wheel 243, and the first conveying wheel 233 and the first pressing wheel 236 pull the steel bar out of the extrusion tube 223 and convey the steel bar to the detection tube 32. When the steel bar passes through the detection tube 32, the circumferentially evenly distributed detection steel balls 322 adaptively roll and fit with the surface of the steel bar. When the steel bar still has a bent section after being straightened once, the bent steel bar squeezes the detection steel ball 322, thereby compressing the detection telescopic column 321. The sensor in the detection telescopic column 321 is squeezed and sends an electrical signal, which indicates that the steel bar still has a bent section and needs to be straightened again. At this time, the first conveying motor 237 stops working immediately, and the first conveying motor 237 stops working immediately. The feeding wheel 233 and the second pressing wheel 246 stop conveying the steel bars and only squeeze and clamp the steel bars, while the second conveying wheel 243 continues to work, and the second conveying wheel 243 and the second pressing wheel 246 continue to pull the steel bars, and the steel bars between the first conveying wheel 233 and the second conveying wheel 243 are straightened for a second time until the detection steel ball 322 returns to the normal position, and the sensor in the detection telescopic column 321 no longer sends an electrical signal, the first conveying motor 237 is restarted, and the first conveying wheel 233 conveys the steel bars again; in this process, the power gear 248 rotates with the second conveying wheel 243, so that the transition gear 249 meshing with it rotates, and then drives the follower rotating wheel 333 to rotate, so that the cleaning cylinder 33 and the detection cylinder 32 rotate in the rotating frame 31, and the steel wire 332 in the cleaning cylinder 33 removes rust and dust on the steel bars to maintain the cleanliness of the steel bars, and the removed rust and dust fall into the dust collecting box 34 through the dust collecting groove 331.

[0058] The end of the steel bar transported by the second conveying wheel 243 passes through the first V-shaped seat 87 and moves to the second V-shaped seat 96. When the end of the steel bar moves to the cut-off plate 92, the cut-off button 97 is pressed and pressed. At this time, the first conveying motor 237 and the second conveying motor 247 stop working, and the first conveying wheel 233 and the second conveying wheel 243 no longer transport the steel bar. The first electric pressure rod 81 and the second electric pressure rod 94 work to press the first squeezing pad 86 and the second squeezing pad 95 downward respectively. The first squeezing pad 86 and the first V-shaped seat 87 and the second squeezing pad 95 and the second V-shaped seat 96 clamp the steel bar respectively. At the same time, the cutting motor 84 The cutting knife 83 is driven to cut the steel bars. Under the push of the first electric pressure rod 81, the cutting knife 83 cuts off the steel bars. During this process, the elastic column 85 is compressed, the first squeezing pad 86 and the first V-shaped seat 87 squeeze and clamp the steel bars to be transported, and the second squeezing pad 95 and the second V-shaped seat 96 squeeze and clamp one end of the cut steel bars; finally, the first electric pressure rod 81 and the second electric pressure rod 94 are contracted, and the cut steel bars fall from the collecting trough 62 into the drawer box 61 due to gravity. The end close to the first V-shaped seat 87 falls first, and the second V-shaped seat 96 can rotate with it, so that the steel bars fall completely into the drawer box 61.

[0059] When the first electric pressure rod 81 and the second electric pressure rod 94 are reset, the first conveying motor 237 and the second conveying motor 247 are started again, the first conveying wheel 233 and the second conveying wheel 243 continue to convey the steel bars, and the above-mentioned cutting process is repeated, thereby realizing the continuity of the fixed-length cutting of the steel bars; when the length of the steel bars needs to be changed, it is only necessary to re-adjust the indicating position of the indicating block 93 through the fixed-length threaded rod 75, and the efficiency of steel bar cutting is relatively high.

[0060] It is worth noting that the use of the spring structure and the sensor are both existing technologies and will not be described in detail here.
