Description

Technical Field

[0001] The present application relates to the technical field of conveying equipment, and in particular to a bar conveyor. Background Art

[0002] At present, a bar conveyor is a device used to transport bar-shaped materials and is often used in conjunction with equipment for continuously processing bar-shaped materials.

[0003] In related technologies, a bar conveyor generally includes a frame, a conveyor belt, and a motor. Rotating rollers are rotatably provided at both ends of the frame. The conveyor belt is arranged along the length direction of the frame and wound around the two rotating rollers. The motor is fixed on the frame and connected to one of the rotating rollers. During transportation, the motor is started, and the bar is placed on the conveyor belt. The conveyor belt drives the bar to move from the loading end of the frame to the unloading end of the frame, completing the transportation of the bar.

[0004] In view of the above related technologies, the inventor found that since the bar is prone to deviation and rolling during transportation, when the bar moves to the unloading end of the frame, it is often scattered and needs to be adjusted one by one before the next processing, so there is room for improvement. Summary of the Invention

[0005] In order to improve the neatness of bar transportation, the present application provides a bar conveyor.

[0006] The bar conveyor provided by the present application adopts the following technical solutions:

[0007] A bar conveyor includes a frame. Above the frame, there is a material storage box for holding bars. The bottom wall of the material storage box is provided with a discharge port. The material storage box is provided with a control component for opening and closing the discharge port. Between the discharge port and the frame, there is a correction component for adjusting the orientation of the bar. On the frame, there is a conveying component for driving the bar to move along the length direction of the frame. One end of the conveying component is used to support the corrected bar, and the other end extends along the length direction of the frame to the end of the frame away from the correction component.

[0008] By adopting the above technical solutions, the discharge port is opened through the control component, and the bar falls out of the discharge port under the action of gravity. The fallen bar is adjusted by the correction component and then falls on the conveying component. The conveying component transports the bar to the end of the frame away from the correction component, which is beneficial to improving the neatness of the bar during transportation.

[0009] Optionally, the correction component includes a plurality of correction rods. The plurality of correction rods are arranged on the frame. The plurality of correction rods are uniformly arranged along the width direction of the frame. The correction rods extend along the length direction of the frame. A gap for a single bar to pass through is formed between adjacent correction rods.

[0010] By adopting the above technical solution, when the bar stock falling from the discharge port drops, the bar stock that is not parallel to the correction rod will hit the correction rod. The bar stock that falls into the gap after hitting the correction rod and the bar stock that directly falls into the gap will both land on the conveying assembly after passing through the gap. Since both the correction rod and the gap extend along the length direction of the frame, the axes of the bar stock passing through the gap are all perpendicular to the width direction of the frame, which is beneficial to improving the neatness of the bar stock during conveying.

[0011] Optionally, a pair of baffles for blocking the downward movement of the bar stock are arranged on the correction rod. The two baffles are rotatably connected to the bottom wall of the correction rod. The two baffles both extend along the length direction of the correction rod. At least one torsion spring is connected between the baffle and the correction rod;

[0012] The torsion spring is used to push the baffles on adjacent correction rods to approach each other.

[0013] By adopting the above technical solution, when the first bar stock falls into the gap, the first bar stock continues to move downward until one end abuts against the baffle. At this time, the other end of the first bar stock rotates towards the baffle under the action of gravity. When the other end of the first bar stock rotates to abut against the baffle, the axis of the first bar stock is parallel to the length direction of the frame. At this time, the torsion spring is deformed by force, and the distance between the two baffles increases. When the second bar stock falls into the gap and fits against the first bar stock, the torsion spring is further deformed by the increased force, and the distance between the two baffles increases. When the distance between the baffles is large enough for the bar stock to pass through, the first bar stock falls onto the conveying assembly. After the first bar stock falls, the torsion spring returns, the distance between the baffles decreases, and the second bar stock is supported, realizing the adjustment of each bar stock to be parallel to the length direction of the frame one by one, which is beneficial to further improving the neatness of the bar stock during conveying.

[0014] Optionally, a pair of installation grooves are formed in the bottom wall of the correction rod. The installation grooves correspond to the baffles one by one. The installation grooves extend along the length direction of the correction rod. The baffles are rotatably arranged in the corresponding installation grooves. A plug rod is arranged in the installation groove. The plug rod extends along the length direction of the installation groove. One end of the plug rod penetrates through the groove wall of the installation groove, and the other end is fixed with a plug block. A slot for inserting the plug block is formed through the groove wall of the installation groove. The torsion spring is sleeved on the plug rod. One end of the torsion spring abuts against the bottom of the installation groove, and the other end abuts against the baffle.

[0015] By adopting the above technical solution, when the weights of the conveyed bar stocks are different, the staff can pull out the plug block. The plug block drives the plug rod and the torsion spring to pass through the slot, and then adjusts the number of torsion springs on the plug rod to adjust the resistance that needs to be overcome when the two baffles rotate to allow the bar stock to pass through, which is beneficial to adapting to more bar stocks with different weights.

[0016] Optionally, a straightening plate for pushing the bar stock into the gap is slidably arranged on the frame. The straightening plate extends along the length direction of the straightening rod. A first lead screw is rotatably arranged on the frame. The first lead screw extends along the width direction of the frame. The first lead screw is threadedly connected to the straightening plate. A straightening motor for driving the first lead screw to rotate is fixed on the frame.

[0017] By adopting the above technical solution, when there is bar stock on adjacent straightening rods, start the straightening motor. The straightening motor drives the first lead screw to rotate. The first lead screw pushes the straightening plate to move along the width direction of the frame. The straightening plate pushes the bar stock on the straightening rod, making the bar stock parallel to the straightening plate. When the bar stock moves above the gap, the bar stock falls into the gap, realizing pushing the bar stock on adjacent two straightening rods into the gap, which is beneficial to reducing the possibility of bar stock not falling into the gap accumulating on the straightening rods.

[0018] Optionally, the straightening rods are slidably connected to the frame. A pair of scissors arms are connected between several straightening rods. The intersection points of the two scissors arms correspond to the straightening rods one by one. The straightening rods are connected to the corresponding intersection points of the scissors arms.

[0019] By adopting the above technical solution, the scissors arms keep the distance between adjacent two straightening rods equal. When the distance between adjacent two straightening rods approaches, all the straightening rods move synchronously, realizing adjusting the distance between adjacent two straightening rods, thereby adjusting the width of the gap, which is beneficial to adapting to more bar stocks with different diameters.

[0020] Optionally, the conveying assembly includes a conveyor belt, a driving motor and several limiting plates. The conveyor belt extends along the length direction of the frame to both ends of the frame. The driving motor is fixed on the frame, and the driving motor is used for driving the conveyor belt to rotate. The limiting plates are arranged on the frame. The limiting plates are arranged corresponding to the straightening rods one by one. The distance between adjacent two limiting plates is equal to the distance between adjacent two straightening rods.

[0021] By adopting the above technical solution, when conveying the bar stock, the driving motor drives the conveyor belt to rotate towards the end of the frame away from the straightening rod. Since the limiting plates are arranged corresponding to the straightening rods one by one, and the distance between adjacent two limiting plates is equal to the distance between adjacent two straightening rods, the bar stock falls between adjacent two limiting plates after passing through the gap and abuts against the conveyor belt. The driving motor drives the bar stock to move towards the end of the frame away from the straightening rod through the conveyor belt.

[0022] Optionally, the limiting plates are slidably connected to the frame, and the limiting plates slide along the width direction of the frame. A synchronizing rod is connected between the limiting plates and the corresponding straightening rods.

[0023] By adopting the above technical solution, when it is necessary to adjust the distance between adjacent limiting plates to adapt to bar stocks of different diameters, it is only necessary to adjust the distance between two adjacent synchronous rods. When the distance between two adjacent synchronous rods decreases, the distance between two adjacent limiting plates and the distance between two adjacent straightening rods decrease synchronously, realizing synchronous adjustment of the positions of the limiting plates and the straightening rods, which is beneficial to adapting to more bar stocks of different diameters.

[0024] Optionally, the control assembly includes a cover plate, a second lead screw, and an opening and closing motor. The cover plate is slidably disposed at the bottom of the material storage box, and the cover plate is used to seal the discharge port. The second lead screw is rotatably disposed at the bottom of the material storage box, and the axis of the second lead screw is parallel to the width direction of the frame. The second lead screw is threadedly connected to the cover plate, and the opening and closing motor is disposed on the material storage box and is used to drive the second lead screw to rotate.

[0025] By adopting the above technical solution, when it is necessary to open the discharge port, start the opening and closing motor. The opening and closing motor drives the second lead screw to rotate, and the second lead screw pushes the cover plate to move towards or away from the discharge port, realizing control of the opening and closing of the discharge port, thereby controlling the feeding and stopping of the bar stock.

[0026] Optionally, a partition is provided in the material storage box. The partition is inclined, a material guiding port is opened at the bottom end of the partition, a through groove is formed through the side wall of the material storage box, and a sealing plate for sealing the material guiding port is slidably disposed in the through groove. An electric push rod for pushing the sealing plate to slide towards or away from the material guiding port is disposed on the material storage box.

[0027] By adopting the above technical solution, the bar stocks in the material storage box are stacked on the partition. Start the electric push rod, and the electric push rod drives the sealing plate to move away from the material guiding port, and the material guiding port is opened. Under the action of gravity, the bar stocks move along the partition towards the material guiding port, and after passing through the material guiding port, the bar stocks are stacked on the cover plate. Then, the electric push rod is used to push the sealing plate towards the material guiding port to close the material guiding port, which is beneficial to controlling the feeding amount of the bar stocks.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] After the first bar stock falls into the gap, the first bar stock continues to move downward until one end abuts against the baffle. When the other end of the first bar stock rotates to abut against the baffle, the axis of the first bar stock is parallel to the length direction of the frame at this time. The torsion spring is stressed and deformed, and the distance between the two baffles increases. When the second bar stock falls into the gap and fits against the first bar stock, the force on the torsion spring increases and further deforms, and the distance between the baffles continues to increase. When the distance between the baffles is large enough for the bar stock to pass through, the first bar stock drops onto the conveying assembly. After the first bar stock drops, the torsion spring returns, the distance between the baffles decreases and supports the second bar stock, realizing the adjustment of each bar stock to be parallel to the length direction of the frame one by one, which is beneficial to further improve the neatness of the bar stock during conveying;

[0030] When the weights of the conveyed bar stocks are different, the staff can pull out the insertion block. The insertion block drives the insertion rod and the torsion spring to pass through the slot, and then adjusts the number of torsion springs on the insertion rod to adjust the resistance that needs to be overcome when the two baffles rotate until the bar stock can pass through, which is beneficial to adapting to more bar stocks with different weights;

[0031] The scissor arms keep the distances between adjacent two correction rods equal. When the distances between adjacent two correction rods approach, all the correction rods move synchronously to adjust the distances between adjacent two correction rods, thereby adjusting the width of the gap, which is beneficial to adapting to more bar stocks with different diameters.

[0038] The following further elaborates on this application Figures 1-5 in conjunction with the accompanying drawings.

[0039] An embodiment of this application discloses a bar stock conveyor. Referring to Figure 1 and Figure 2 , a bar stock conveyor includes a frame 1, a material storage box 2 is erected above the frame 1, and a discharge port 21 is opened on the bottom wall of the material storage box 2. A control assembly 3 is arranged at the bottom of the material storage box 2, and the control assembly 3 is used to close or open the discharge port 21. A correction assembly 4 is arranged between the discharge port 21 and the frame 1, and the correction assembly 4 is used to adjust the orientation of the bar stock 6. A conveyor assembly 5 for driving the bar stock 6 to move along the length direction of the frame 1 is installed on the frame 1. One end of the conveyor assembly 5 is used to support the bar stock 6 after correction, and the other end extends along the length direction of the frame 1 to the end of the frame 1 away from the correction assembly 4.

[0040] By opening the discharge port 21 through the control assembly 3, the bar stock 6 falls out of the discharge port 21 under the action of gravity. The fallen bar stock 6 is adjusted by the correction assembly 4 and then falls on the conveyor assembly 5. The conveyor assembly 5 conveys the bar stock 6 to the end of the frame 1 away from the correction assembly 4, which is beneficial to improving the neatness of the bar stock 6 during transportation.

[0041] Referring to Figure 1 and Figure 2, the control component 3 includes a cover plate 31, a second lead screw 32 and an opening and closing motor 33. The cover plate 31 is slidably arranged at the bottom of the material storage box 2 and slides along the width direction of the frame 1. The bottom of the side wall of the material storage box 2 is rotatably connected with the second lead screw 32, and the axis of the second lead screw 32 is parallel to the width direction of the frame 1. A moving groove is formed through the bottom of the side wall of the material storage box 2. The moving groove extends along the axial direction of the second lead screw 32, and a moving block is slidably arranged in the moving groove. The second lead screw 32 is threadedly connected to the moving block. The opening and closing motor 33 is fixed to the bottom of the side wall of the material storage box 2, and the output shaft of the opening and closing motor 33 is coaxially and fixedly connected to one end of the second lead screw 32. When it is necessary to open the discharge port 21, the opening and closing motor 33 is started. The opening and closing motor 33 drives the second lead screw 32 to rotate. The second lead screw 32 pushes the cover plate 31 to move towards or away from the discharge port 21, so as to control the opening and closing of the discharge port 21, and thus control the feeding and stopping of the bar stock 6.

[0042] Refer to Figure 1 and Figure 2 , a partition plate 22 is fixed in the material storage box 2, and the periphery of the partition plate 22 fits the inner side wall of the material storage box 2. The partition plate 22 is inclined, and a material guiding port 221 is formed at the bottom end of the partition plate 22. A through groove 24 is formed through the side wall of the material storage box 2, and the length direction of the through groove 24 is parallel to the length direction of the frame 1. A sealing plate 23 is slidably arranged in the through groove 24, and the sealing plate 23 slides along the width direction of the frame 1. An electric push rod 25 is fixed to the side wall of the material storage box 2, and the end of the output shaft of the electric push rod 25 faces the side wall of the sealing plate 23 away from the partition plate 22, and the end of the output shaft of the electric push rod 25 is fixedly connected to the side wall of the sealing plate 23 away from the partition plate 22.

[0043] The bar stock 6 in the material storage box 2 accumulates on the partition plate 22. The electric push rod 25 is started. The electric push rod 25 drives the sealing plate 23 to move away from the material guiding port 221, and the material guiding port 221 is opened. Under the action of gravity, the bar stock 6 moves along the partition plate 22 towards the material guiding port 221, and after passing through the material guiding port 221, the bar stock 6 accumulates on the cover plate 31. Then, the electric push rod 25 is used to push the sealing plate 23 towards the material guiding port 221, and the material guiding port 221 is closed, which is beneficial to controlling the feeding amount of the bar stock 6.

[0044] Refer to Figure 2 and Figure 3The correction assembly 4 includes a plurality of correction rods 41. A vertical plate 11 is fixed to the top of the frame 1. A slide groove 111 is provided on the side wall of the vertical plate 11 facing the correction rod 41. The slide groove 111 extends along the width direction of the frame 1. Slide blocks 422 are fixed to the side walls of the correction rods 41 facing the slide groove 111. The slide blocks 422 are slidably connected to the slide groove 111. The correction rods 41 are evenly arranged along the width direction of the frame 1. The correction rods 41 extend along the length direction of the frame 1. A gap is formed between adjacent correction rods 41 for a single bar 6 to pass through. A horizontal plate 115 is fixed to the top of the frame 1. The horizontal plate 115 is located on the side of the correction rod 41 away from the vertical plate 11. The horizontal plate 115 reduces the possibility of the bar 6 falling from the end of the correction rod 41 away from the vertical plate 11.

[0045] Reference Figure 3 and Figure 4 The bottom wall of the correction rod 41 is provided with a pair of mounting grooves 413, which extend along the length direction of the correction rod 41. A baffle 43 is rotatably arranged in the mounting groove 413, which extends along the length direction of the correction rod 41, and the bottom end of the baffle 43 is bent toward the adjacent gap. At least one torsion spring 415 is arranged in the mounting groove 413. In the embodiment of the present application, the number of torsion springs 415 is set to five, and the torsion spring 415 is used to push the baffle 43 and the baffles 43 on the adjacent correction rod 41 to approach each other. In the embodiment of the present application, since the baffles 43 need to be matched in pairs, the baffles 43 at both ends are removed. The top wall of the correction rod 41 is covered with a buffer strip 411, which reduces the wear and noise caused by collision when the bar 6 falls on the top wall of the correction rod 41.

[0046] When the first bar 6 falls into the gap, the first bar 6 continues to descend until one end abuts against the baffle 43. At this time, the other end of the first bar 6 rotates toward the baffle 43 under the action of gravity. When the other end of the first bar 6 rotates to abut against the baffle 43, the axis of the first bar 6 is parallel to the length direction of the frame 1. At this time, the torsion spring 415 is deformed by force, and the distance between the two baffles 43 increases. When the second bar 6 falls into the gap and fits the first bar 6, the torsion spring 415 is further deformed by the force increased, and the distance between the two baffles 43 increases. When the distance between the baffles 43 is large enough for the bar 6 to pass, the first bar 6 falls onto the conveying assembly 5. After the first bar 6 falls, the torsion spring 415 is restored, the distance between the baffles 43 is reduced and supports the second bar 6, so that the bars 6 are adjusted one by one to be parallel to the length direction of the frame 1, which is beneficial to further improve the neatness of the bars 6 during transportation.

[0047] Reference Figure 3 and Figure 5, a plug rod 414 is arranged in the installation groove 413, and the plug rod 414 extends along the length direction of the installation groove 413. One end of the plug rod 414 penetrates through the groove wall of the installation groove 413 close to the vertical plate 11, and a plug block 4141 is fixed at the other end. A slot 4131 for inserting the plug block 4141 is penetrated and opened on the groove wall of the installation groove 413 far from the vertical plate 11, and a handle 4142 is fixed on the side wall of the plug block 4141 facing away from the plug rod 414. Refer to Figure 3 and Figure 4 , five torsion springs 415 are all sleeved on the plug rod 414. One end of the torsion spring 415 abuts against the bottom of the installation groove 413, and the other end abuts against the baffle 43.

[0048] When the weights of the conveyed rod materials 6 are different, the staff can pull out the plug block 4141. The plug block 4141 drives the plug rod 414 and the torsion spring 415 to pass through the slot 4131, and then adjusts the number of the torsion springs 415 on the plug rod 414 to adjust the resistance that needs to be overcome when the two baffles 43 rotate to allow the rod material 6 to pass through, which is beneficial to adapting to more rod materials 6 with different weights. When installing the torsion spring 415, glue is applied to the installation point corresponding to the plug rod 414. The glue can reduce the possibility of slipping between the torsion spring 415 and the plug rod 414, and reduce the possibility of uneven installation caused by the slipping of the torsion spring 415 on the plug rod 414 when installing the plug rod 414.

[0049] Refer to Figure 2 , a correction plate 1131 is arranged on the side wall of the vertical plate 11. A strip-shaped groove 113 is penetrated and opened on the side wall of the vertical plate 11. The strip-shaped groove 113 extends along the width direction of the frame 1, and the correction plate 1131 is slidably connected to the strip-shaped groove 113. A first lead screw 1132 is rotatably arranged in the strip-shaped groove 113. The first lead screw 1132 extends along the width direction of the frame 1, and the first lead screw 1132 is threadedly connected to the correction plate 1131. The correction plate 1131 extends along the length direction of the correction rod 41 to the end of the correction rod 41 facing away from the vertical plate 11. A correction motor 114 is fixed on the side wall of the vertical plate 11. The output shaft of the correction motor 114 penetrates through the vertical plate 11 and extends into the strip-shaped groove 113, and the output shaft of the correction motor 114 is coaxially and fixedly connected to one end of the first lead screw 1132. A pressing plate 412 is fixed on the top wall of the correction rod 41 far from the correction plate 1131, which reduces the possibility that the rod material 6 falls on the correction rod 41 far from the correction plate 1131 and cannot be pushed into the gap.

[0050] When there is a bar 6 on the adjacent straightening rods 41, start the straightening motor 114. The straightening motor 114 drives the first lead screw 1132 to rotate. The first lead screw 1132 pushes the straightening plate 1131 to move along the width direction of the frame 1. The straightening plate 1131 pushes the bar 6 on the straightening rods 41, making the bar 6 parallel to the straightening plate 1131. When the bar 6 moves above the gap, the bar 6 falls into the gap, realizing pushing the bar 6 on the adjacent two straightening rods 41 into the gap, which is beneficial to reducing the possibility of the bar 6 that has not fallen into the gap accumulating on the straightening rods 41.

[0051] Refer to Figure 1 and Figure 2 As shown in FIGS. and, the conveying assembly 5 includes a conveyor belt 51, a driving motor 53, a pair of rotating rollers 52 and a plurality of limiting plates 54. The conveyor belt 51 extends along the length direction of the frame 1 to both ends of the frame 1. Rotating rollers 52 are rotatably provided at both ends of the frame 1, and the axes of the rotating rollers 52 are all parallel to the width direction of the frame 1. The conveyor belt 51 is wound around the two rotating rollers 52. The driving motor 53 is fixed on one side of the frame 1 close to the vertical plate 11, and the output shaft of the driving motor 53 is coaxially and fixedly connected to the rotating roller 52 close to the vertical plate 11.

[0052] One ends of the plurality of limiting plates 54 are all slidably connected to the vertical plate 11, and pulleys are provided at the bottoms of the other ends. The pulleys are abutted against the conveyor belt 51. Compared with using a supporting object such as a support block to support the end of the limiting plate 54 away from the vertical plate 11, when using a pulley to support the limiting plate 54, the frictional resistance that needs to be overcome when the conveyor belt 51 works is smaller, slowing down the wear speed of the conveyor belt 51 and reducing the load on the driving motor 53. The limiting plates 54 slide along the width direction of the frame 1, and the limiting plates 54 are arranged in one-to-one correspondence with the straightening rods 41. Chamfered corners are provided at the top edges on both opposite sides of the limiting plates 54 in the width direction. The chamfered corners are beneficial to straightening the bar 6 that deflects during falling and guiding it into the space between two adjacent limiting plates 54, which is beneficial to reducing the possibility that the bar 6 cannot fall into the space between two adjacent limiting plates 54 due to deflection.

[0053] When conveying the bar 6, the driving motor 53 drives the conveyor belt 51 to rotate towards the end of the frame 1 away from the straightening rods 41. Since the limiting plates 54 are arranged in one-to-one correspondence with the straightening rods 41, and the distance between two adjacent limiting plates 54 is equal to the distance between two adjacent straightening rods 41, the bar 6 falls between two adjacent limiting plates 54 after passing through the gap and abuts against the conveyor belt 51. The driving motor 53 drives the bar 6 to move towards the end of the frame 1 away from the straightening rods 41 through the conveyor belt 51.

[0054] Refer to Figure 2 and Figure 3, a plurality of correction rods 41 are connected by a pair of scissors arms 42. Fixed shafts at the intersection points of the two scissors arms 42 are fixedly connected with synchronizing rods 421, and the synchronizing rods 421 correspond to the correction rods 41 one by one. The synchronizing rods 421 are arranged vertically. A second chute 112 is formed on the side wall of the vertical plate 11 facing the synchronizing rods 421. A second slider 422 is fixed on the side wall of the synchronizing rod 421 facing the second chute 112, and the second slider 422 is slidably connected to the second chute 112. The top end of the synchronizing rod 421 is fixedly connected to one end of the correction rod 41 facing the vertical plate 11, and the bottom end of the synchronizing rod 421 is fixedly connected to one end of the limiting plate 54 facing the vertical plate 11.

[0055] The scissors arms 42 keep the distances between adjacent two correction rods 41 equal. When the distances between adjacent two correction rods 41 approach, all the correction rods 41 move synchronously, so as to adjust the distances between adjacent two correction rods 41, thereby adjusting the width of the gap, which is beneficial to adapting to more bar materials 6 with different diameters. When it is necessary to adjust the distances between adjacent limiting plates 54 to adapt to bar materials 6 with different diameters, only the distances between adjacent two synchronizing rods 421 need to be adjusted. When the distances between adjacent two synchronizing rods 421 decrease, the distances between adjacent two limiting plates 54 and the distances between adjacent two correction rods 41 decrease synchronously, so as to synchronously adjust the positions of the limiting plates 54 and the correction rods 41, which is beneficial to adapting to more bar materials 6 with different diameters.

[0056] The implementation principle of an embodiment of a bar conveyor in this application is as follows: start the opening and closing motor 33, the opening and closing motor 33 drives the second lead screw 32 to rotate, the second lead screw 32 pushes the cover plate 31 to move away from the discharge port 21, and the bar material 6 carried on the cover plate 31 falls under the action of gravity. The bar material 6 parallel to the correction rod 41 and facing the gap directly passes through the gap and falls on the baffle 43;

[0057] After the previous bar material 6 falls into the gap, the previous bar material 6 continues to move downward until one end abuts against the baffle 43. At this time, the other end of the previous bar material 6 rotates towards the baffle 43 under the action of gravity. When the other end of the previous bar material 6 rotates to abut against the baffle 43, the axis of the previous bar material 6 is parallel to the length direction of the frame 1. At this time, the torsion spring 415 deforms under force, and the distance between the two baffles 43 increases. When the next bar material 6 falls into the gap and fits against the previous bar material 6, the torsion spring 415 is stressed and deformed further, and the distance between the two baffles 43 increases. When the distance between the baffles 43 is large enough for the bar material 6 to pass through, the previous bar material 6 falls onto the conveying assembly 5. After the previous bar material 6 falls, the torsion spring 415 returns and pushes the baffle 43 to rotate, and the distance between the two baffles 43 decreases and supports the next bar material 6, so as to adjust each bar material 6 to be parallel to the length direction of the frame 1 one by one, which is beneficial to further improving the neatness of the bar material 6 during conveying;

[0058] Start the correction motor 114. The correction motor 114 drives the first lead screw 1132 to rotate. The first lead screw 1132 pushes the correction plate 1131 to move along the width direction of the frame 1. The correction plate 1131 pushes the bar stock 6 on the correction rod 41, making the bar stock 6 parallel to the correction plate 1131. When the bar stock 6 moves above the gap, the bar stock 6 falls into the gap, realizing the pushing of the bar stock 6 resting on the adjacent two correction rods 41 into the gap;

[0059] The bar stock 6 falls onto the conveyor belt 51 away from the baffle 43. The limiting plate 54 forms a rotational limiting effect on the bar stock 6, making the orientation of the bar stock 6 always remain parallel to the length direction of the frame 1, which is beneficial to improving the neatness of the bar stock 6 during transportation.

[0060] The embodiments of this specific implementation manner are all preferred embodiments of this application. Without limiting the protection scope of this application accordingly, therefore: Any equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
