[0002] On a steel bar production line, straight steel bars are generally used as raw materials to produce various shaped steel bar products. Since straight steel bars have the characteristic that the length is much greater than the diameter, there are problems of crossing for bundled steel bars, which affects the feeding efficiency. Moreover, the self-weight of the steel bars is relatively large, and there are problems of bending deformation of the steel bars during the process of grasping and feeding the steel bars. It is difficult to connect steel bar conveying mechanisms at different heights, and the equipment cost is high. There are great potential safety hazards in the process of grasping and transporting the steel bars from the storage rack to the feeding rack. Not only is the labor intensity of workers large, but also the work efficiency is low. Therefore, there is an urgent need for an automated device for feeding steel bars to improve the production efficiency of steel bars and reduce the labor intensity of workers.

[0087] The present invention provides a steel bar combing and feeding device, as Figures 1 - 3 shown, which includes a flattening device 1, a material taking device 2, a combing device 3 and a material blocking device 4 arranged in sequence along a first direction (X direction), wherein,

[0088] The flattening device 1 includes a first group of chain platforms 11 and a second group of chain platforms 12 arranged in sequence along the first direction. The first group of chain platforms 11 and the second group of chain platforms 12 have an overlapping area along the first direction; the long axis direction of the steel bar 100 is along a second direction (Y direction), the second direction is perpendicular to the first direction, the steel bar 100 is supported on the first group of chain platforms 11, and the steel bar 100 completes the flattening action during the process of being conveyed from the first group of chain platforms 11 to the second group of chain platforms 12;

[0089] The material taking device 2 can move along the first direction and a third direction (Z direction), the third direction (Z direction), the second direction (Y direction) and the first direction (X direction) are perpendicular to each other pairwise. The material taking device 2 can move up and down along the third direction to grab the steel bar 100 from the second group of chain platforms 12 and clamp the steel bar 100 to drive the steel bar 100 to move along the first direction to above the combing device 3;

[0090] The combing device 3 includes two groups of combing members 31, the two groups of combing members 31 are arranged at intervals along the second direction on both sides of the material taking device 2, and the two groups of combing members 31 can move away from the material taking device 2 and comb the steel bar 100, so that the steel bar 100 is completely transferred from the flattening device 1 to the combing device 3;

[0091] The material blocking device 4 is arranged at the output end of the carding device 3 to receive the carded steel bars 100. The material blocking device 4 can be rotated to close to cut off the steel bars 100 or rotated to open to release the steel bars 100 for feeding.

[0092] The steel bar carding and feeding equipment provided by the present invention sequentially arranges a flattening device 1, a material taking device 2, a carding device 3 and a material blocking device 4 along the first direction on the steel bar 100 production line. The material taking device 2 is arranged at a high position and can move up and down. The bundled steel bars 100 can first be flattened and conveyed by the flattening device 1, solving the problem that the cross-overlapping of the steel bars 100 affects the single-piece feeding; the material taking device 2 is used to grab and move the flattened steel bars 100 above the carding device 3. Since the two ends of the steel bars 100 droop due to gravity during the grabbing and moving process, that is, bending deformation, the steel bars 100 need to be carded before being conveyed for feeding. The two carding members 31 of the carding device 3 move away from the material taking device 2 on both sides below the material taking device 2 to realize the carding of the steel bars 100, correcting the bending deformation of the steel bars 100. At this time, the material taking device 2 releases the steel bars 100, so that the steel bars 100 are completely transferred from the flattening device 1 to the carding device 3. The output end of the carding device 3 automatically controls the cut-off and feeding of the steel bars 100 through the material blocking device 4, thereby realizing the continuous automatic carding and feeding of the steel bars 100, and having the advantages of high automation degree, low labor intensity, safety and reliability, and high production efficiency.

[0093] In some embodiments, the flattening device 1 further includes a flattening base frame 13 and a transmission shaft. The first support beam 131 and the second support beam 132 are arranged at intervals along the first direction on the flattening base frame 13; the transmission shaft includes a first transmission shaft 14 and a second transmission shaft 15. The first transmission shaft 14 and the second transmission shaft 15 are arranged at intervals along the first direction between the first support beam 131 and the second support beam 132, and the first transmission shaft 14 is located between the second support beam 132 and the second transmission shaft 15; the first group of chain platforms 11 includes a plurality of first chain drive assemblies, and the two ends of the plurality of first chain drive assemblies are respectively rotatably connected to the first support beam 131 and the first transmission shaft 14; the second group of chain platforms 12 includes a plurality of second chain drive assemblies, and the two ends of the plurality of second chain drive assemblies are respectively rotatably connected to the second support beam 132 and the second transmission shaft 15.

[0094] Such as Figure 2 and Figure 8In the illustrated embodiment, the first set of chain platforms 11 includes six first chain drive assemblies spaced apart in the second direction to support and convey the steel bars 100, and the second set of chain platforms 12 includes six second chain drive assemblies spaced apart in the second direction to support and convey the steel bars 100. An overlapping area is formed between the first set of chain platforms 11 and the second set of chain platforms 12 between the first transmission shaft 14 and the second transmission shaft 15. When the steel bars 100 are conveyed to this overlapping area, by controlling and adjusting the conveying speeds of the first set of chain platforms 11 and the second set of chain platforms 12 or changing the conveying directions (one conveys forward and the other conveys backward), the steel bars 100 are flattened. As Figure 5 shown, for the convenience of design and description, the first set of chain platforms 11 and the second set of chain platforms 12 have the same structure, except for differences in length and installation positions. Taking the first set of chain platforms 11 as an example, the six first chain drive assemblies have the same structure. The first chain drive assembly includes a flattening drive member 111 and a first motor sprocket 112 provided at the output end of the flattening drive member 111. A first transmission sprocket 113 is fixedly provided on the first transmission shaft 14. The first motor sprocket 112 and the first transmission sprocket 113 are connected by a first transmission chain 114, thereby transmitting the output power of the flattening drive member 111 to the rotation of the first transmission shaft 14. A plurality of conveying sprockets 115 are arranged in pairs on the first transmission shaft 14 and the first support beam 131. A conveying chain 117 is connected between the two conveying sprockets 115 in a pair, thereby realizing synchronous rotation and transmission of the plurality of first chain drive assemblies to convey the steel bars 100. It can be understood that among the two conveying sprockets 115, one is used as the driving sprocket and is fixedly connected to the first transmission shaft 14, and the other is used as the driven sprocket and is rotatably connected to the first support beam 131. Without special instructions, the rotational connection is all in the form of bearing connection. A flattening tensioning assembly 116 is further provided on the flattening base frame 13. The flattening tensioning assembly 116 includes a flattening tensioning bracket 1161 and a flattening tensioning wheel 1162 rotatably connected to the flattening tensioning bracket 1161.

[0095] In some embodiments, the material taking device 2 includes a cross beam 21, a transverse moving frame 22, a transverse moving driving member 23, a clamping assembly 24 and a material taking assembly 25. Among them, the cross beam 21 is arranged above the flattening device 1 and the carding device 3 in the third direction; so that after the material taking device 2 grabs and clamps the steel bar 100, it can move from above the flattening device 1 to above the carding device 3. The transverse moving frame 22 is slidably connected to the cross beam 21, and the sliding direction is along the first direction; the transverse moving driving member 23 is arranged on the cross beam 21, and the output end of the transverse moving driving member 23 is connected to the transverse moving frame 22 to drive the transverse moving frame 22 to slide along the first direction; the clamping assembly 24 includes a clamping driving member 241 and a plurality of clamping arms 242. The plurality of clamping arms 242 are arranged in pairs and are respectively rotatably connected to the transverse moving frame 22. The output end of the clamping driving member 241 is connected to the two clamping arms 242 of each pair and can drive the two clamping arms 242 to rotate and close or rotate and open simultaneously to clamp or release the steel bar 100; the material taking assembly 25 includes a material taking driving member 251 and a material taking member 252. The material taking driving member 251 is arranged on the transverse moving frame 22, and the output end of the material taking driving member 251 is connected to the material taking member 252. The material taking driving member 251 is used to drive the material taking member 252 to move up and down in the third direction.

[0096] With the above structure, when taking materials, the material taking assembly 25 moves above the flattening device 1. The material taking driving member 251 drives the material taking member 252 to move downward and contact the steel bar 100, then grabs a steel bar 100 and drives the steel bar 100 to move upward. Until the steel bar 100 contacts the clamping assembly 24, the clamping driving member 241 drives the clamping arms 242 to rotate and close to clamp the steel bar 100. Then the transverse moving driving member 23 drives the transverse moving frame 22 to move, and further drives the material taking assembly 25 and the clamping assembly arranged on the transverse moving frame 22 to move synchronously, moving the clamping position of the steel bar 100 above the carding device 3, so as to facilitate the carding device 3 to card the steel bar 100 and meet the feeding requirements. Preferably, the transverse moving driving member 23, the clamping driving member and the material taking driving member 251 all adopt linear driving mechanisms, such as cylinders, and can also be oil cylinders or linear motors, etc.

[0097] In some embodiments, the material taking assembly 25 further includes a guiding seat 253 and a first guiding shaft 254. The output end of the material taking driving member 251 is connected to the guiding seat 253, and the material taking member 252 is elastically installed on the guiding seat 253; the top end of the first guiding shaft 254 is fixedly connected to the transverse moving frame 22, and the bottom end of the first guiding shaft 254 passes through the guiding seat 253, and the guiding seat 253 can move up and down along the first guiding shaft 254.

[0098] Such as Figure 9 and Figure 10As shown, the function of the first guiding shaft 254 is to guide the lifting movement of the material taking driving part 251 and the guiding seat 253. Therefore, a linear bearing can be adopted for the first guiding shaft 254. There are two first guiding shafts 254, which are respectively arranged on both sides of the material taking driving part 251, facilitating to ensure the stability of the lifting movement of the guiding seat 253. It can be understood that the bottom end of the first guiding shaft 254 is fixedly connected to the guiding seat 253, and the top end is slidably connected to the body of the material taking driving part 251 or the transverse moving frame 22, which can also achieve the same guiding effect. For example Figure 10 , the bottom end of the first guiding shaft 254 is fixedly connected to the guiding seat 253, a guide sleeve 255 is arranged on the transverse moving frame 22, and the first guiding shaft 254 passes through the guide sleeve 255 to be slidably connected to the transverse moving frame 22. When the material taking driving part 251 drives the guiding seat 253 to move up and down, the first guiding shaft 254 slides in the guide sleeve 255 to achieve guiding.

[0099] In some embodiments, the material taking part 252 includes a material taking rod 2521, a fixed seat 2522 and an elastic part 2523. The top end of the material taking rod 2521 passes through the guiding seat 253 and is limited to the top surface of the guiding seat 253 by a limiting part 2525; the fixed seat 2522 is connected to the bottom end of the material taking rod 2521, and a magnet 2524 is arranged on the fixed seat 2522 for magnetically attracting the steel bar 100; the elastic part 2523 is sleeved on the material taking rod 2521, and both ends of the elastic part 2523 respectively abut against the guiding seat 253 and the fixed seat 2522. Under the action of the elastic force of the elastic part 2523 and the gravity of the fixed seat 2522, the top end of the material taking rod 2521 is limited to the top surface of the guiding seat 253.

[0100] For example Figure 9As shown in the figure, in this embodiment, the material taking assembly 25 is arranged inside the transverse moving frame 22, and the clamping assembly 24 is arranged on the side wall of the transverse moving frame 22. After the material taking member 252 magnetically attracts the steel bar 100, it rises, so that the clamping arms 242 on both sides of the transverse moving frame 22 can clamp the steel bars 100 on both sides. Since the steel bar 100 generates a certain bending deformation under the action of gravity, in this embodiment, the transverse moving frame 22 is set as a hollow structure, so that the material taking member 252 can rise to a position higher than the two clamping arms 242 after magnetically attracting the steel bar 100, so as to facilitate the clamping arms 242 to contact and clamp the steel bar 100. The elastic member 2523 is a spring and is sleeved on the material taking rod 2521. Two material taking rods 2521 are arranged at intervals. The top end of the material taking rod 2521 is slidably installed with the guiding seat 253. Under the action of the gravity of the steel bar 100, the top end of the material taking rod 2521 is limited to the top surface of the guiding seat 253. When magnetically attracting the steel bar 100, when the fixed seat 2522 descends to contact the steel bar 100, it can be buffered under the action of the elastic member 2523 to avoid damage caused by hard contact magnetic attraction. In some embodiments, the limiting member 2525 can be a nut. External threads are provided at the top end of the material taking rod 2521 to threadedly connect the nut, so as to facilitate adjusting the position of the magnet 2524, so that the material taking assembly 25 and the clamping assembly 24 can realize the position adjustment of the cooperative work.

[0101] In some embodiments, the material taking device 2 further includes a second guiding shaft 26. The second guiding shaft 26 is fixedly connected to the cross beam 21, and the transverse moving frame 22 is slidably connected to the second guiding shaft 26. Preferably, the second guiding shaft 26 also cooperates with a guiding sleeve 255 to realize sliding guiding. Here, the guiding sleeve 255 is arranged on the transverse moving frame 22, and the second guiding shaft 26 is symmetrically arranged on both sides of the transverse moving driving member 23 for guiding.

[0102] In some embodiments, the combing device 3 further includes a combing frame 32, a combing driving member 33, a combing transmission mechanism 34 and a third chain transmission assembly 35. There are two combing driving members 33, and the two combing driving members 33 are arranged on the combing frame 32 at intervals along the second direction. The two combing driving members 33 are respectively arranged on both sides of the material taking device 2 along the second direction; there are two combing transmission mechanisms 34, and the two combing transmission mechanisms 34 are respectively arranged at the output ends of the two combing driving members 33; there are two third chain transmission assemblies 35, and the two ends of the two third chain transmission assemblies 35 are respectively rotatably connected to the combing frame 32, and the driving ends of the two third chain transmission assemblies 35 are respectively drivingly connected to the output ends of the two combing transmission mechanisms 34. Two groups of combing members 31 are respectively fixedly connected to the two third chain transmission assemblies 35. The two combing driving members 33 respectively drive the two third chain transmission assemblies 35 to transmit in the reverse direction through the two combing transmission mechanisms 34, so that the two groups of combing members 31 move away from the material taking device 2.

[0103] As Figure 4As shown, two groups of combing members 31 are symmetrically arranged on the combing frame 32. In this embodiment, each group of combing members 31 includes six combing members 31. The two groups of combing members 31 are driven to move by the combing driving member 33, the combing transmission mechanism 34 and the third chain transmission assembly 35 respectively. The two groups of combing members 31 on both sides move from the middle to both sides in the horizontal direction along the second direction to comb both sides of the steel bar 100 clamped on the material taking device 2, so that the bent and drooping parts of the steel bar 100 can also be completely transferred to the combing device 3. It can be understood that the length of the third chain transmission assembly 35 on both sides must meet the support requirements of the length of the steel bar 100.

[0104] The combing drive member 33 uses a rotation drive mechanism such as a reduction motor to output rotational motion, and a second motor sprocket 331 is provided at the output end of the combing drive member 33. The second motor sprocket 331 is connected to the combing transmission mechanism 34 through a second transmission chain 332. Figure 7 As shown, the combing transmission mechanism 34 includes a second transmission sprocket 341, a combing main shaft 342 and a combing sprocket 343, wherein the second transmission sprocket 341 is connected to the second motor sprocket 331 through a second transmission chain 332 to realize the transmission output of the combing drive member 33. The second transmission sprocket 341 is fixed on the combing main shaft 342, and the combing sprocket 343 is fixed on the combing main shaft 342. The combing main shaft 342 realizes the synchronous rotation transmission of the combing sprocket 343 and the second transmission sprocket 341, and the combing sprocket 343 is connected to the third chain transmission assembly 35 through the combing chain 344 (as shown in FIG. Figure 4 ). Further, if Figure 7 As shown, the combing main shaft 342 is rotatably supported on the combing frame 32 through two bearings (with vertical seat bearings 345), and the combing sprocket 343 is fixed on the combing main shaft 342 between the two bearings. The combing sprocket 343 is isolated and positioned by the shaft diameter on the combing main shaft 342 and the spacer sleeve 346 set between it and the second transmission sprocket.

[0105] like Figure 6 As shown, the third chain transmission assembly 35 includes a first tensioning bracket 351, a first tensioning wheel 352 and a bearing circular guide rail. The first tensioning bracket 351 is fixed on the combing frame 32, and the combing tensioning wheel is rotatably connected to the combing frame 32 through the combing shaft 354. The first tensioning wheel 352 is connected to the combing frame 32 through the combing sprocket 343 (as shown in FIG. Figure 4 ) is connected to the combing sprocket 343 to achieve transmission connection. The bearing circular guide is arranged on the outer periphery of the combing sprocket 343 to support the combing member 31 and the steel bar 100. The combing member 31 is connected to the combing chain 344 and slides on the bearing circular guide. Preferably, the combing member 31 and the bearing circular guide are connected by a bolt-type roller needle bearing 355. Figure 6As shown, the first tensioning bracket 351 is passed through and connected to two connecting rods of the carding frame 32. Bolts are respectively provided on both sides of the first tensioning bracket 351 on the two connecting rods. By adjusting the positions of the bolts on the connecting rods, the position adjustment between the first tensioning bracket 351 and the carding frame 32 can be achieved.

[0106] In some embodiments, the carding device 3 further includes a carding tensioning assembly 36. The carding tensioning assembly 36 is adjustably mounted on the carding frame 32 and can tension the third chain drive assembly 35 along the third direction.

[0107] As Figure 4 shown, there are multiple carding tensioning assemblies 36. The multiple carding tensioning assemblies 36 are arranged at intervals along the second direction and are used for tensioning and adjusting the carding chain 344. As Figure 8 shown, the carding tensioning assembly 36 includes a second tensioning bracket 361 and a second tensioning wheel 362. The second tensioning bracket 361 is adjustably mounted on the carding frame 32. Specifically, the second tensioning bracket 361 is connected to the carding frame 32 by long bolts, and multiple nuts are threadedly connected to the long bolts. The position of the second tensioning bracket 361 is adjusted and locked by bolts on both sides to achieve adjustable position. The second tensioning wheel 362 is rotatably connected to the second tensioning bracket 361 through a pin shaft 363, and the second tensioning wheel 362 is drivingly connected to the carding chain 344 to achieve the tensioning adjustment of the carding chain 344. Preferably, a sleeve 364 is provided between the second tensioning wheel 362 and the pin shaft 363 for isolation and positioning.

[0108] In some embodiments, the carding member 31 includes a connecting portion 311 and a carding portion 312. The connecting portion 311 is fixedly connected to the third chain drive assembly 35; the carding portion 312 is fixedly connected to one end of the connecting portion 311 facing the flattening device 1, and the carding portion 312 protrudes from the surface of the connecting portion 311 and can contact and card the steel bar 100.

[0109] As Figure 8 shown, the carding member 31 is integrally arranged in an L-shaped hook structure. The carding portion 312 of the carding member 31 is a structure that protrudes from the conveying plane of the carding chain 344, so that the part of the steel bar 100 located above the carding chain 344 can contact the carding portion 312 when the taking device 2 is in a suitable position. The two carding portions 312 move away from each other respectively, and gradually card the steel bar 100 onto the carding device 3, that is, both ends of the steel bar 100 are transferred onto the carding device 3 under the action of the carding portion 312. It can be understood that the height setting of the carding portion 312 takes into account the distance between the steel bar 100 on the taking device 2 and the carding device 3.

[0110] In some embodiments, one end of the connecting portion 311 away from the flattening device 1 is inclined downward. A material guiding portion 321 is provided on the carding frame 32 and is inclined. The connecting portion 311 and the material guiding portion 321 are connected in sequence to continuously convey the steel bar 100. As Figure 8 shown, there is a certain inclination angle between the connecting portion 311 of the carding member 31 and the conveying plane of the carding chain 344. When the steel bar 100 is transferred to the carding device 3 under the action of the carding portion 312, due to the inclined setting of the connecting portion 311, the steel bar 100 can automatically slide downward under its own gravity for collection and stop at the material blocking device 4. According to the processing of the carding frame 32 and the installation space of the material blocking device 4, in order to ensure the smooth sliding of the steel bar 100, a material guiding portion 321 is provided on the carding frame 32. The material guiding portion 321 is inclined downward to facilitate the further sliding of the steel bar 100. The material guiding portion 321 and the connecting portion 311 may have the same inclination angle, or the material guiding portion 321 may have a larger inclination angle to facilitate the faster sliding and collection of the steel bar 100 at the material blocking device 4.

[0111] In some embodiments, the carding device 3 further includes a supporting member 37. The supporting member 37 is provided on the third chain transmission assembly 35 and is spaced apart from the carding member 31. The supporting member 37, the carding member 31, and the material guiding portion 321 have the same inclination angle to facilitate the downward sliding of the steel bar 100 under its own gravity.

[0112] Combined with Figure 4 and Figure 8 , a plurality of supporting members 37 are provided. The plurality of supporting members 37 are arranged on two groups of the third chain transmission assemblies 35 and are used to support and protect the carding chain 344. The body structure of the supporting member 37 is the same as that of the connecting portion 311 of the carding member 31 and is inclined on the carding chain 344. The difference lies in the bending direction of the two ends of the supporting member 37. In the carding portion 312 of the carding member 31, the end with a higher height of the connecting portion 311 is bent upward to card the steel bar 100; both ends of the supporting member 37 are bent downward relative to the carding chain 344. The downward bending of the end with a higher height can avoid blocking the steel bar 100, and the downward bending of the end with a lower height is conducive to the cooperation and connection with the material guiding portion 321 to achieve transitional connection.

[0113] In some embodiments, the material blocking device 4 includes a material blocking driving member 41, a linkage plate 42, a rotating plate 43 and a material receiving arm 44. The material blocking driving member 41 is arranged on the carding frame 32. The linkage plate 42 is movably connected to the output end of the material blocking driving member 41 and extends along the second direction. A plurality of rotating plates 43 are provided, and the plurality of rotating plates 43 are arranged at intervals along the second direction on the linkage plate 42 and are rotatably connected to the linkage plate 42. A rotating shaft is provided on the carding frame 32, and the two ends of the rotating shaft are respectively connected to the material receiving arm 44 and the rotating plate 43 in a rotating connection. The telescopic movement of the material blocking driving member 41 can drive the linkage plate 42 to move along the second direction and drive the rotation of the material receiving arm 44 to open or close through the rotating plate 43.

[0114] The present invention also provides a method for carding and feeding steel bars, which applies the steel bar carding and feeding equipment provided by the present invention and combines Figures 11 - 19 , and the steel bar carding and feeding method includes the following steps:

[0115] S1. Place the whole bundle of steel bars 100 on the flattening device 1 for bundling breaking and conveying. A plurality of steel bars 100 are conveyed to the lower part of the material taking device 2 and flattened;

[0116] As Figure 11 shown, the bundled steel bars 100 can be placed on the first group of chain platforms 11 of the flattening device 1 through a crane or other lifting and hoisting equipment for bundling breaking. Then start the flattening device 1, and the steel bars 100 are conveyed along the first direction towards the material taking device 2. When part of the steel bars 100 are conveyed to the first group of chain platforms 11, stop the first group of chain platforms 11 from conveying the steel bars 100, and the second group of chain platforms 12 continue to convey the steel bars 100 towards the material taking device 2 and stop when they are conveyed to the lower part of the material taking device 2, as Figure 12 shown.

[0117] S2. The material taking device 2 grabs and clamps the steel bars 100 to drive the steel bars 100 to move above the carding device 3 along the first direction;

[0118] Specifically:

[0119] After the flattened steel bars 100 are conveyed in place, start the output end of the material taking driving member 251 to extend and drive the material taking member 252 to move downward and grab (magnetically attract) the steel bars 100, as Figure 13 shown;

[0120] The output end of the material taking driving member 251 contracts and drives the material taking member 252 to drive the steel bars 100 to move upward until it stops at the position where the clamping assembly 24 can clamp the steel bars 100 (which can be designed in advance), as Figure 14 .

[0121] The clamping driving member 241 drives the two clamping arms 242 to act and clamp the steel bars 100, as Figure 15 ;

[0122] The transverse movement driving member 23 is activated, and the output end of the transverse movement driving member 23 contracts and drives the entire transverse movement frame 22 to move towards the carding device 3. The clamped part in the middle of the steel bar 100 then reaches above the carding device 3, as Figure 16 .

[0123] S3. The two carding members 31 of the carding device 3 move away from the material taking device 2 respectively to card the steel bar 100 from the middle to both sides, so that the steel bar 100 is completely transferred from the flattening device 1 to the carding device 3;

[0124] It should be added that when the carding device 3 is in the initial position, as Figures 11 - 15 , the support member 37 is located on the side close to the material taking device 2, thereby being able to avoid blocking the steel bar 100 during the movement of the steel bar 100. During carding, as Figure 16 , the two carding members 31 move upward from the middle position of the two carding transmission mechanisms 34. The two third chain transmission assemblies 35 have opposite conveying directions, so that the two carding members 31 have a movement from the middle to both sides. After the multiple carding members 31 contact the steel bar 100 in sequence, the steel bar 100 is carded to the carding device 3.

[0125] S4. The material taking device 2 releases the steel bar 100, and the steel bar 100 falls onto the carding device 3 and slides to the material blocking device 4 to prepare for feeding;

[0126] As Figure 17 , the clamping driving member 241 drives the two clamping arms 242 to rotate and open, and the steel bar 100 is released onto the carding device 3. After the steel bar 100 is released, under the action of the carding member 31, it slides downward along the connecting portion 311 from one side of the carding portion 312; when the carding member 31 rotates to below the carding chain 344 (here referring to the upper conveying plane of the carding chain 344) again, the support member 37 rotates to above the carding chain 344, and the steel bar 100 slides from top to bottom and stops at the material blocking device 4 when passing through the material guiding portion 321, as Figure 18 .

[0127] After the clamping driving member 241 releases the steel bar 100, the clamping driving member 241 drives the two clamping arms 242 to rotate and close a part and return to the initial state (as Figure 18 ), so as to facilitate clamping the steel bar 100 next time. The output end of the transverse movement driving member 23 extends and sends the entire material taking device 2 above the flattening device 1, and resets to the initial state to facilitate taking the next steel bar 100.

[0128] S5. The material blocking device 4 rotates and opens, and the steel bar 100 slides under the action of gravity to the next process to realize feeding;

[0129] As Figure 19, the material blocking driving part 41 of the material blocking device 4 is started, and multiple material receiving arms 44 rotate synchronously to open. The steel bar 100 slides downward under its own gravity to the next process, realizing the feeding of the steel bar 100.

[0130] S6. Repeat steps S2 - S5 until the feeding of the whole bundle of steel bars 100 is completed.

[0131] The steel bar combing and feeding method provided by the present invention, when applying the steel bar combing and feeding equipment provided by the present invention, realizes the continuous and automatic combing and feeding of the steel bar 100, effectively reduces the labor intensity of workers on the production line, the feeding process of the steel bar 100 is safe and reliable, and the production efficiency is high.

[0132] In step S1, the flattening process of multiple steel bars 100 is as follows:

[0133] When the steel bar 100 is conveyed along the first group of chain platforms 11 to the staggered area between the first group of chain platforms 11 and the second group of chain platforms 12, the first group of chain platforms 11 and the second group of chain platforms 12 convey the steel bar 100 in two directions, forward and backward respectively along the conveying direction, until the steel bar 100 is flattened.

[0134] Repeat the actions of the first group of chain platforms 11 and the second group of chain platforms 12 to convey the steel bar 100 forward and backward until the steel bar 100 under the material taking device 2 is flattened.

[0135] Obviously, the above - mentioned embodiments of the present invention are only examples for clearly explaining the present invention, and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re - adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
