Description

TECHNICAL FIELD

[0001] The application relates to the field of screw manufacturing, and in particular to a roller feeding machine for screw manufacturing. BACKGROUND

[0002] In the automobile manufacturing and parts industry, as a key basic fastener, the production quality and efficiency of the screw directly affect the assembly accuracy and safety of the whole vehicle. In the screw manufacturing process, a roller is often used as a raw material for continuous feeding, and the stability and reliability of the feeding machine play an important role in ensuring the forming quality of the screw and reducing material loss. Therefore, the roller feeding device for screw manufacturing has become one of the key equipment in the field.

[0003] The existing roller feeding machine for screw production usually adopts a support frame structure arranged obliquely, relies on the self-weight of the roller to roll along the inclined surface to realize automatic feeding, and installs a limiting stop bar on the support frame during feeding to keep the roller stable on the support frame. Then, an obliquely arranged Z-shaped lifting rod is used to move the roller close to the limiting stop bar. The roller is lifted by the lifting rod, the lifting rod is arranged obliquely, and after the lifting rod lifts the roller away from the limiting stop bar, the roller rolls along the lifting rod to the other end of the lifting rod, and then the lifting rod is lowered to place the roller on the support wheel for feeding.

[0004] However, in actual use, the roller often accelerates on the inclined surface of the lifting rod without constraint, resulting in a violent collision with the end structure of the lifting rod. Not only does this easily cause damage and deformation of the surface of the roller, affecting the subsequent screw machining quality, but it also produces a large impact noise, which deteriorates the workshop working environment. SUMMARY

[0005] The application aims to solve the problem that the roller often accelerates on the inclined surface of the lifting rod without constraint, resulting in a violent collision with the end structure of the lifting rod. Not only does this easily cause damage and deformation of the surface of the roller, affecting the subsequent screw machining quality, but it also produces a large impact noise, which deteriorates the workshop working environment. The application provides a roller feeding machine for screw manufacturing.

[0006] The application specifically adopts the following technical solutions to achieve the above-mentioned purpose:

[0007] A roller feeder for screw manufacturing includes a support frame with several support braces fixed on it. A feeding frame is located on one side of the support frame and is fixed to the ground. Several feeding wheels are rotatably connected to the feeding frame. A conveying device is installed at one end of the feeding frame. Limiting rods are fixed to the ends of the support braces near the feeding frame. Lifting rods are located on the sides of the support braces away from the limiting rods. The lifting rods are Z-shaped. A fixed seat is fixed to the side of the support frame near the feeding frame. Two symmetrical lifting cylinders are fixed to the fixed seat. A lifting base is located on the fixed seat and is fixedly connected to the telescopic ends of the lifting cylinders. An auxiliary material transfer mechanism is provided between the lifting rods and the lifting base. A conveying stabilizing mechanism is provided between the lifting rods and the lifting base.

[0008] By adopting the above technical solution, when the roller is lifted by the lifting rod, the auxiliary material transfer mechanism on the lifting rod abuts against the direction of the roller's rolling. The auxiliary material transfer mechanism controls the rolling speed of the roller on the lifting rod. At the same time, during the process of the auxiliary material transfer mechanism driving the roller to move, the conveying stabilizing mechanism limits the moving roller. In this way, when the lifting rod lifts the roller, it can reduce the possibility of the roller rolling rapidly on the lifting rod due to the tilt of the lifting rod and its own weight, which would cause the roller to hit the end of the lifting rod and cause collision damage. At the same time, it can reduce the rolling impact noise of the roller during feeding and reduce the feeding noise generated by the feeding machine.

[0009] Furthermore, the auxiliary material transfer mechanism includes a movable rod fixed on the lifting rod, an auxiliary stop bar is provided on the movable rod, a movable component is provided between the movable rod and the auxiliary stop bar, a synchronization component is provided on the feeding frame, the synchronization component corresponds to the movable rod on several lifting rods, and the lifting seat is fixedly connected to the movable rod.

[0010] By adopting the above technical solution, when the lifting rod lifts the roller, the auxiliary stop bar on the moving rod blocks the roller. The auxiliary stop bar drives the roller on the lifting rod to slowly move to the end of the lifting rod. This reduces the possibility of the roller rolling rapidly on the lifting rod due to the tilt of the lifting rod and its own weight, which could cause the roller to hit the end of the lifting rod and cause damage. At the same time, it can reduce the rolling and impact noise of the roller during feeding, and reduce the feeding noise generated by the feeding machine.

[0011] Furthermore, the movable component includes a movable block fixed on an auxiliary stop bar, a movable groove corresponding to the movable block is provided on the movable rod, a movable threaded rod is rotatably connected to the movable rod, the movable threaded rod is located in the movable groove on the movable rod, the movable threaded rod passes through the movable block and is threadedly connected to the movable block.

[0012] By adopting the above technical solution, the movable threaded rod drives the movable block to move along the movable groove, and the movable block drives the auxiliary stop rod to move, thereby making it convenient for the movable block to drive the auxiliary stop rod to move on the movable rod.

[0013] Furthermore, the synchronization component includes a synchronization plate mounted on the feeding rack, one end of several moving rods being fixedly connected to a synchronization rod, several drive shafts being rotatably connected to the synchronization rod, the drive shafts passing through the synchronization rod and the moving rods and being fixedly connected to a moving threaded rod, gears being fixedly mounted on the drive shafts, chains being drivingly connected between several gears, limiters being provided between adjacent gears, and a drive motor being fixedly mounted on the synchronization plate, the output end of the drive motor being fixedly connected to one of the drive shafts.

[0014] By adopting the above technical solution, the gear drives the chain, and the chain drives several other gears to rotate under the limit of the limiting component, thereby enabling several moving blocks to move simultaneously and several auxiliary baffles to move synchronously.

[0015] Furthermore, the limiting component includes a connecting seat fixed on the synchronizing rod, two symmetrical limiting shafts fixed on the connecting seat, sleeves rotatably connected to the limiting shafts, and the chain passing between the two sleeves.

[0016] By adopting the above technical solution, during the movement of the chain, the chain drives the sleeve to rotate on the limiting shaft, and at the same time, the chain is fastened to the gear, thereby reducing the possibility of the gear and chain falling off when the chain drives several gears.

[0017] Furthermore, the conveying stabilizing mechanism includes a sliding block disposed on an auxiliary stop bar. The auxiliary stop bar has a sliding groove, the sliding block is located in the sliding groove and is slidably connected to the auxiliary stop bar, the sliding block is provided with a stabilizing limit rod, an adjusting component is disposed between the stabilizing limit rod and the sliding block, and a following pressing component is disposed between the sliding block and the moving rod.

[0018] By adopting the above technical solution, the auxiliary stop lever drives the sliding block, which in turn drives the stabilizing limit lever to move above the moving roller on the lifting rod. This limits the movement of the roller on the lifting rod, improves the stability of the roller's movement on the lifting rod, reduces the possibility of collisions during roller movement, and reduces the possibility of the roller tilting during feeding.

[0019] Furthermore, the following pressing assembly includes a following block rotatably connected to the sliding block, a connecting rod fixed to one end of the moving rod near the feeding frame, a moving guide rod fixed to the connecting rod, and the moving guide rod passing through the following block and slidably connected to the following block.

[0020] By adopting the above technical solution, the following block, guided by the moving guide rod, causes the sliding block to move in the direction of the moving rod, thereby enabling the sliding block to move the stabilizing limit rod in the direction of the roller under the guidance of the moving guide rod.

[0021] Furthermore, the adjusting assembly includes an adjusting rod fixed on the sliding block, an adjusting threaded rod threadedly connected to the adjusting rod, the adjusting threaded rod passing through the adjusting rod and fixedly connected to the stabilizing limit rod, and a sliding rod slidably connected to the adjusting rod, the sliding rod passing through the adjusting rod and fixedly connected to the stabilizing limit rod.

[0022] By adopting the above technical solution, rotating the adjusting threaded rod allows it to move on the adjusting rod, which in turn drives the stabilizing limit rod. This makes it easy to adjust the distance between the stabilizing limit rod and the lifting rod, thus facilitating the limiting of rollers of different diameters.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, when the lifting cylinder drives the lifting seat, the lifting seat drives the moving rod, which in turn drives the lifting rod to rise. The lifting rod lifts the roller that was stopped by the limit stop. After the roller is freed from the limit stop, an auxiliary stop on the moving rod restricts the roller. A synchronous component drives the moving component, which moves on the moving rod. The moving component drives the auxiliary stop, which slowly moves towards the lifting rod and towards the feeding frame. Then the roller moves along the lifting rod. After the moving component drives the auxiliary stop to the end of the lifting rod, the auxiliary stop disengages from the roller, and the roller then contacts the lifting cylinder. At the end of the lifting rod, the lifting cylinder drives the moving rod to descend, which in turn drives the lifting rod to descend, allowing the roller on the lifting rod to fall onto the feeding wheel of the feeding frame. After the roller moves away from the feeding wheel on the feeding frame, the auxiliary stop and lifting rod are reset to prepare for the feeding of the next roller. This achieves the goal of reducing the possibility of the roller rolling rapidly on the lifting rod due to the tilt of the lifting rod and its own weight when the lifting rod lifts it up, thus reducing the possibility of the roller hitting the end of the lifting rod and causing collision damage. At the same time, it can also reduce the rolling impact noise of the roller during feeding, thereby reducing the feeding noise generated by the feeding machine.

[0025] 2. In this application, while the auxiliary stop bar moves on the moving rod, the auxiliary stop bar drives the sliding block, the sliding block drives the following block, and the following block moves along the moving guide rod. The moving guide rod first tilts towards the moving rod and then remains parallel to the moving rod. Under the guidance of the moving guide rod, the following block drives the sliding block to move towards the moving rod. The sliding block drives the stabilizing limit rod to move, so that the stabilizing limit rod is located above the roller on the lifting rod. This achieves the purpose of limiting the roller on the lifting rod, improving the stability of the roller's movement on the lifting rod, reducing the possibility of the roller colliding during movement, and reducing the possibility of the roller tilting during feeding.

[0026] 3. In this application, by having a drive motor drive one of the drive shafts to rotate on a synchronous plate, the drive shaft drives the corresponding gear, the gear drives the chain, and the chain drives several other gears to rotate under the limitation of the limiting component. The gear drives the corresponding drive shaft, and the drive shaft drives the moving threaded rod, allowing the moving threaded rod to rotate in the moving rod, thereby achieving the purpose of enabling several moving blocks to move simultaneously and keeping several auxiliary baffles moving synchronously, thus improving the stability of the roller movement.

[0037] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0038] This application discloses a roller feeder for screw manufacturing.

[0039] Reference Figure 1 , Figure 2 and Figure 3 A roller feeder for screw manufacturing includes a support frame 1, on which several support rods 2 are fixed. A feeding frame 4 is provided on one side of the support frame 1 and is fixed to the ground. Several feeding wheels 5 are rotatably connected to the feeding frame 4. A conveying device 3 is installed at one end of the feeding frame 4. Limiting stops 6 are fixed to the ends of the several support rods 2 near the feeding frame 4. Lifting rods 9 are provided on the side of the several support rods 2 away from the limiting stops 6. The lifting rods 9 are Z-shaped. A fixed seat 11 is fixed to the side of the support frame 1 near the feeding frame 4. Two symmetrical lifting cylinders 12 are fixed on the fixed seat 11. A lifting seat 10 is provided on the fixed seat 11. The lifting seat 10 is fixedly connected to the telescopic end of the lifting cylinders 12. An auxiliary material transfer mechanism 7 is provided between the lifting rods 9 and the lifting seat 10. A conveying stabilizing mechanism 8 is provided between the lifting rods 9 and the lifting seat 10.

[0040] When using this feeding machine, several rollers are placed on the support inclined rods 2 on the support frame 1. The support inclined rods 2 support the rollers, and the limit stop rods 6 on the support inclined rods 2 support the rollers to prevent them from rolling off the support inclined rods 2. When feeding is required, the lifting cylinder 12 on the fixed seat 11 is used to lift the rollers. The extension end of the lifting cylinder 12 drives the lifting seat 10, and the lifting seat 10 drives the lifting rod 9. The lifting rod 9 lifts the rollers, and the rollers are released from the restriction of the limit stop rod 6 and roll along the inclined lifting rod 9 towards the feeding frame 4. At the same time, the lifting rod 9... The auxiliary material transfer mechanism 7 abuts against the roller in the direction of movement, restricting the roller to move slowly on the lifting rod 9. Simultaneously, the auxiliary material transfer mechanism 7 drives the conveying stabilizing mechanism 8, causing it to abut against the roller, allowing the roller to move stably on the lifting rod 9. When the auxiliary material transfer mechanism restricts the roller to the end of the lifting rod 9, the lifting cylinder 12 descends, and the lifting seat 10 drives the lifting rod 9, causing the roller on the lifting rod 9 to fall onto the feeding wheel 5 on the feeding frame 4. The conveying device 3 consists of two conveying wheels, a conveying motor, and a clamping cylinder. One feeding wheel is fixed to the feeding frame 4 and driven by the conveyor motor. Another wheel is slidably connected to the conveyor frame and driven by the clamping cylinder. When the roller comes into contact with the feeding wheel 5, the feeding wheel 5 also comes into contact with the conveyor wheel. The clamping cylinder drives the other conveyor wheel to clamp the roller. The conveyor motor drives the conveyor wheel, which in turn drives the roller to move and feed material. After the roller has completely moved away from the feeding wheel 5 on the feeding frame 4, the auxiliary material transfer mechanism 7 and the conveying stabilizing mechanism 8 are reset, ready for feeding the next roller. When the roller is lifted by the lifting rod 9, the auxiliary material transfer mechanism on the lifting rod 9 is used to... The auxiliary material transfer mechanism 7 controls the rolling speed of the roller on the lifting rod 9 by contacting the roller in the direction of its rolling motion. At the same time, during the process of the auxiliary material transfer mechanism 7 driving the roller to move, the conveying stabilizing mechanism 8 limits the movement of the roller. This reduces the possibility of the roller rolling rapidly on the lifting rod 9 due to the tilt of the lifting rod 9 and its own weight, which could cause the roller to hit the end of the lifting rod 9 and cause damage. It also reduces the rolling impact noise when the roller is being fed, thus reducing the feeding noise generated by the feeder.

[0041] Reference Figure 4 , Figure 5 and Figure 6 The auxiliary material transfer mechanism 7 includes a movable rod 72 fixed on the lifting rod 9, an auxiliary stop rod 71 is provided on the movable rod 72, a movable component 73 is provided between the movable rod 72 and the auxiliary stop rod 71, a synchronization component 74 is provided on the feeding frame 4, the synchronization component 74 corresponds to the movable rod 72 on several lifting rods 9, and the lifting seat 10 is fixedly connected to the movable rod 72.

[0042] When the lifting cylinder 12 drives the lifting seat 10, the lifting seat 10 drives the moving rod 72, which in turn drives the lifting rod 9 to rise. The lifting rod 9 lifts the roller that was stopped by the limit stop 6. After the roller is freed from the limit stop 6, the auxiliary stop 71 on the moving rod 72 restricts the roller. The synchronous component 74 drives the moving component 73, which moves on the moving rod 72. The moving component 73 drives the auxiliary stop 71, which slowly moves towards the lifting rod 9 and towards the feeding rack 4. Then the roller moves along the lifting rod 9. After the moving component 73 drives the auxiliary stop 71 to the end of the lifting rod 9, the auxiliary stop 71 disengages from the roller. Then the roller comes into contact with the end of the lifting rod 9, and the lifting cylinder 12 drives the moving rod 72 to descend. The lever 72 drives the lifting lever 9 to descend, allowing the roller on the lifting lever 9 to fall onto the feeding wheel 5 on the feeding frame 4. After the roller moves away from the feeding wheel 5 on the feeding frame 4, the auxiliary stop lever 71 and the lifting lever 9 are reset to prepare for the feeding of the next roller. By using the auxiliary stop lever 71 on the moving lever 72 to block the roller when the lifting lever 9 lifts the roller, the auxiliary stop lever 71 drives the roller on the lifting lever 9 to slowly move to the end of the lifting lever 9. This reduces the possibility of the roller rolling rapidly on the lifting lever 9 due to the tilt of the lifting lever 9 and its own weight, which could cause the roller to hit the end of the lifting lever 9 and cause damage. At the same time, it can reduce the rolling impact noise when the roller is feeding, and reduce the feeding noise generated by the feeding machine.

[0043] Reference Figure 3 and Figure 4 The movable component 73 includes a movable block 731 fixed on the auxiliary stop bar 71, a movable groove corresponding to the movable block 731 is provided on the movable rod 72, a movable threaded rod 732 is rotatably connected to the movable rod 72, the movable threaded rod 732 is located in the movable groove on the movable rod 72, the movable threaded rod 732 passes through the movable block 731 and is threadedly connected to the movable block 731.

[0044] The movable threaded rod 732 rotates within the movable rod 72, causing the movable block 731 to move along the movable groove within the movable rod 72. The movable block 731 then moves the auxiliary stop rod 71. As the auxiliary stop rod 71 moves, the rollers on the lifting rod 9 follow it. By allowing the movable threaded rod 732 to rotate within the movable rod 72, the movable threaded rod 732 drives the movable block 731 to move, thus facilitating the movement of the auxiliary stop rod 71 on the movable rod 72.

[0045] Reference Figure 2 , Figure 5 and Figure 6The synchronization component 74 includes a synchronization plate 741 mounted on the feeding rack 4, one end of several moving rods 72 fixedly connected to the synchronization rod, several drive shafts 743 rotatably connected to the synchronization rod, the drive shafts 743 passing through the synchronization rod and the moving rods 72 and fixedly connected to the moving threaded rod 732, gears 742 fixedly mounted on the drive shafts 743, chains 746 drivingly connecting the several gears 742, limiters 745 provided between adjacent gears 742, and a drive motor 744 fixedly mounted on the synchronization plate 741, the output end of the drive motor 744 fixedly connected to one of the drive shafts 743.

[0046] When the movable threaded rod 732 needs to rotate, the drive motor 744 drives one of the drive shafts 743 to rotate on the synchronous plate 741. The drive shaft 743 drives the corresponding gear 742, the gear 742 drives the chain 746, and the chain 746 drives several other gears 742 to rotate under the limit of the limiting member 745. The gear 742 drives the corresponding drive shaft 743, and the drive shaft 743 drives the movable threaded rod 732, causing the movable threaded rod 732 to rotate in the movable rod 72. By using the chain 746 to make one of the drive shafts 743 rotate, the gears 742 and the chain 746 drive several drive rods to drive the movable threaded rod 732 to rotate simultaneously, thereby enabling several movable blocks 731 to move simultaneously and several auxiliary baffles to move synchronously.

[0047] Reference Figure 5 and Figure 6 The limiting component 745 includes a connecting seat 7451 fixed on the synchronizing rod. Two symmetrical limiting shafts 7452 are fixed on the connecting seat 7451. A sleeve 7453 is rotatably connected to the limiting shaft 7452. The chain 746 passes between the two sleeves 7453.

[0048] Two sleeves 7453 rotating on a limiting shaft 7452 are provided between adjacent gears 742. The distance between the two sleeves 7453 is smaller than the diameter of the gear 742. The chain 746 passes between the two sleeves 7453, and the chain 746 abuts against the sleeves 7453. During the movement of the chain 746, the chain 746 drives the sleeves 7453 to rotate on the limiting shaft 7452, and at the same time, the chain 746 is fastened to the gear 742. By using the sleeves 7453 on the two limiting shafts 7452 to limit the chain 746, the possibility of the gear 742 and the chain 746 falling off when the chain 746 drives several gears 742 can be reduced.

[0049] Reference Figure 4 , Figure 7 and Figure 8The conveying stabilizing mechanism 8 includes a sliding block 81 disposed on an auxiliary stop bar 71. A sliding groove 82 is provided on the auxiliary stop bar 71. The sliding block 81 is located in the sliding groove 82 and is slidably connected to the auxiliary stop bar 71. A stabilizing limit bar 83 is provided on the sliding block 81. An adjusting component 85 is provided between the stabilizing limit bar 83 and the sliding block 81. A following pressing component 84 is provided between the sliding block 81 and the moving rod 72.

[0050] During the movement of the auxiliary stop 71 on the moving rod 72, the auxiliary stop 71 drives the sliding block 81 and the stabilizing limit rod 83 to move. During the movement of the auxiliary stop 71, the following pressing component 84 on the sliding block 81 drives the sliding block 81, which in turn drives the adjusting component 85. The adjusting component 85 drives the stabilizing limit rod 83, causing the stabilizing limit rod 83 to move above the roller. The stabilizing limit rod 83 is used to limit the movement of the roller on the lifting rod 9. By having the auxiliary stop 71 drive the sliding block 81 during the movement of the moving rod 72, and allowing the sliding block 81 to move under the guidance of the following pressing component 84, the sliding block 81 drives the stabilizing limit rod 83 to move above the roller on the lifting rod 9. This limits the movement of the roller on the lifting rod 9, improves the stability of the roller's movement on the lifting rod 9, reduces the possibility of collisions during roller movement, and reduces the possibility of the roller tilting during feeding.

[0051] Reference Figure 4 and Figure 8 The following pressing component 84 includes a following block 841 rotatably connected to the sliding block 81, a connecting rod 843 fixed to one end of the moving rod 72 near the feeding frame 4, a moving guide rod 842 fixed on the connecting rod 843, the moving guide rod 842 passing through the following block 841 and slidably connected to the following block 841.

[0052] When the auxiliary stop lever 71 moves on the moving lever 72, the auxiliary stop lever 71 drives the sliding block 81, the sliding block 81 drives the following block 841, and the following block 841 moves along the moving guide rod 842. The moving guide rod 842 first tilts towards the moving lever 72, and then remains parallel to the moving lever 72. Under the guidance of the moving guide rod 842, the following block 841 drives the sliding block 81 to move towards the moving lever 72. The sliding block 81 drives the stabilizing limit rod 83 to move, so that the stabilizing limit rod 83 is located above the roller on the lifting lever 9. By having the auxiliary stop lever 71 drive the sliding block 81 to move, and the sliding block 81 drives the following block 841 to move on the moving guide rod 842, the sliding block 81 can drive the stabilizing limit rod 83 to move towards the roller under the guidance of the moving guide rod 842.

[0053] Reference Figure 4 and Figure 8The adjusting assembly 85 includes an adjusting rod 851 fixed on a sliding block 81, an adjusting threaded rod 852 threadedly connected to the adjusting rod 851, the adjusting threaded rod 852 passing through the adjusting rod 851 and fixedly connected to a stabilizing limit rod 83, and a sliding rod 853 slidably connected to the adjusting rod 851, the sliding rod 853 passing through the adjusting rod 851 and fixedly connected to the stabilizing limit rod 83.

[0054] When the sliding block 81 moves on the auxiliary stop rod 71, the sliding block 81 drives the adjusting rod 851. The adjusting rod 851 uses the adjusting threaded rod 852 and the sliding rod 853 to drive the stabilizing limit rod 83 to move. Rotating the adjusting threaded rod 852 allows it to move on the adjusting rod 851. The adjusting threaded rod 852 drives the stabilizing limit rod 83, changing the distance between the stabilizing limit rod 83 and the sliding block 81. By allowing the adjusting threaded rod 852 to move on the adjusting block, the adjusting threaded rod 852 drives the distance between the stabilizing limit rod 83 and the adjusting rod 851, thus making it easy to adjust the distance between the stabilizing limit rod 83 and the lifting rod 9, which is convenient for limiting rollers of different diameters.

[0055] Working principle: When using this feeding machine, several rollers are placed on the support inclined rods 2 on the support frame 1. The support inclined rods 2 support the rollers, and the limit stop rods 6 on the support inclined rods 2 support the rollers to prevent them from rolling off the support inclined rods 2. When feeding is required, the lifting cylinder 12 on the fixed seat 11 is used to lift the rollers. The extension end of the lifting cylinder 12 drives the lifting seat 10, and the lifting seat 10 drives the lifting rod 9. The lifting rod 9 lifts the rollers, and the rollers are released from the restriction of the limit stop rod 6. The auxiliary stop rod 71 on the moving rod 72 restricts the rollers, allowing the drive motor 744 to drive one of the drive shafts 743 to move in the same direction. The step plate 741 rotates, the drive shaft 743 drives the corresponding gear 742, the gear 742 drives the chain 746, the chain 746 drives several other gears 742 to rotate under the limit of the limit member 745, the gear 742 drives the corresponding drive shaft 743, the drive shaft 743 drives the movable threaded rod 732, so that the movable threaded rod 732 rotates in the movable rod 72, the movable threaded rod 732 drives the movable block 731, so that the movable block 731 moves along the movable groove in the movable rod 72, the movable block 731 drives the auxiliary stop rod 71 to move, and when the auxiliary stop rod 71 moves, the roller on the lifting rod 9 moves with the auxiliary stop rod 71.

[0056] As the auxiliary stop lever 71 moves on the moving lever 72, the auxiliary stop lever 71 drives the sliding block 81, which in turn drives the following block 841. The following block 841 moves along the moving guide rod 842. The moving guide rod 842 first tilts towards the moving lever 72, and then remains parallel to it. Guided by the moving guide rod 842, the following block 841 drives the sliding block 81 to move towards the moving lever 72, and the sliding block 81 drives the stabilizing limit. The lever 83 moves, positioning the stabilizing limit lever 83 above the roller on the lifting lever 9. The auxiliary stop lever 71 drives the roller to contact the end of the lifting lever 9. The lifting cylinder 12 drives the moving lever 72 to descend, which in turn drives the lifting lever 9 to descend, allowing the roller on the lifting lever 9 to fall onto the feeding wheel 5 on the feeding frame 4. After the roller moves away from the feeding wheel 5 on the feeding frame 4, the auxiliary stop lever 71, the lifting lever 9, and the stabilizing limit lever 83 are reset, preparing for the feeding of the next roller.
