Description

Technical Field

[0001] The present application relates to the technical field of feeders, and in particular to an automatic loading device of an automatic bar feeder. Background Art

[0002] An automatic bar feeder is a feeding machine that works with equipment that can continuously process bar materials to achieve automatic feeding, thereby improving the processing efficiency and degree of automation of the equipment.

[0003] Chinese patent publication number CN210346339U discloses a heating furnace loading device, which includes a steel bar loading rack, a steel bar conveyor rack, and a steel bar rotating rack device disposed between the steel bar loading rack and the steel bar conveyor rack. The steel bar loading rack has a higher rear end and a lower front end. A stopper is provided at the front end of the steel bar loading rack to prevent the steel bars from slipping. The bars to be processed are neatly placed on the steel bar loading rack. The steel bar rotating rack device can transfer the steel bars from the steel bar loading rack to the steel bar conveyor rack.

[0004] The steel bar conveyor frame includes a conveyor frame and a plurality of feed rollers installed on the conveyor frame. Double sprockets are installed on the shaft ends of all the feed rollers. One sprocket of the double sprockets at one end is connected to the driving sprocket at the motor shaft end through a chain, and the other sprocket is connected to the corresponding sprocket of the adjacent double sprocket through a chain. The other sprocket of the adjacent double sprocket is further connected to the corresponding sprocket of the adjacent double sprocket through a chain, and so on.

[0005] When loading, the whole bundle of bars is first lifted onto the steel bar loading rack. The operator arranges the bars neatly by dragging, pulling, and throwing them by hand. Then the steel bar turntable device can transfer the steel bars on the steel bar loading rack to the steel bar conveyor rack. The feeding rollers rotate to convey the single bar to the subsequent metal processing equipment.

[0006] With respect to the above-mentioned related technologies, the inventors believe that the bar materials are long and heavy, and the operators have high labor intensity and low efficiency when placing the bar materials, which reduces the overall loading efficiency of the loading device. Summary of the Invention

[0007] In order to improve the problem that manually placing bars on a steel bar loading rack is inefficient and reduces the overall loading efficiency of the loading device, the present application provides an automatic loading device for an automatic bar feeder.

[0008] The present application provides an automatic feeding device for an automatic bar feeder, which adopts the following technical solution:

[0009] An automatic feeding device of an automatic bar feeder comprises a frame, a feeding frame, a conveying frame, a bar rotating frame device, a feeding device provided on the conveying frame, and a pair of stoppers provided on the feeding frame, further comprising a baffle plate, a spreading device for flattening the bar on the feeding frame, and a turning device for driving the feeding frame to rotate, wherein one end of the feeding frame close to the conveying frame is hinged to the frame, and one end of the feeding frame away from the conveying frame is overlapped on the turning device, and the turning device is provided on the frame;

[0010] The material spreading device is provided on the loading rack, the material baffle is provided on the machine frame and is located between the baffle and the material spreading device, and the material baffle is provided with a material passing hole for a bar material to pass through;

[0011] One end of the bar material rotating rack device is arranged on the loading rack, and the other end of the bar material rotating rack device is arranged on the conveying rack.

[0012] By employing this technical solution, after a bundle of bars is hoisted onto the steel bar loading rack, the bars are spread out in a row on the rack using a spreading device. The rack is then tilted by a tilting device, tilting its top surface. Under the influence of its own gravity, the bars on the rack roll toward the conveyor rack. The limiting action of the feed hole further increases the likelihood that a single bar will abut against the stopper. The bar turret device then transfers the individual bars to the conveyor, which then transports them to subsequent metalworking equipment.

[0013] Compared with manually placing the bars in a row on the loading rack, the use of a spreading device can save the operator's physical strength and improve work efficiency, thereby improving the overall loading efficiency of the entire loading device.

[0014] Optionally, the material spreading device includes a material spreading lifting cylinder, a lifting plate and a material spreading mechanism for flattening the rod material on the loading rack. The material spreading lifting cylinder is arranged on the loading rack, the lifting plate is arranged on the driving end of the material spreading lifting cylinder, and the material spreading mechanism is arranged on the lifting plate.

[0015] By adopting the above technical solution, the spreading mechanism can be driven to rise and fall by the spreading lifting cylinder, so that the spreading mechanism can push the bars at different heights and place the bars in a row on the loading rack.

[0016] Optionally, the material spreading mechanism includes a material spreading plate, a material spreading drive assembly and a plurality of material spreading assemblies for driving the material spreading plate to spread the material, and the material spreading drive assembly is provided on the lifting plate for driving the material spreading assembly;

[0017] One end of a plurality of the material spreading components is arranged on the material spreading plate, and the other end of a plurality of the material spreading components is arranged on the material spreading driving component.

[0018] By adopting the above technical solution, the material spreading drive assembly drives several material spreading assemblies to act simultaneously, and the simultaneous action of the material spreading assemblies can drive the material spreading plates to push the rods, so that the rods can fall onto the loading rack.

[0019] Compared to using a single driving point to move the spreading plate, the spreading plate may tilt away from the driving point. When the spreading plate pushes the bar, the bar is unevenly stressed and tilted, preventing it from landing on the loading rack. Or, after landing on the loading rack, the bar's movement trajectory may deviate as it continues to roll. By using multiple spreading components to push the spreading plate simultaneously, the spreading plate can move more stably, ensuring a more even force on the bar when the spreading plate pushes it. This allows the bar to land more smoothly on the loading rack and roll down along the loading rack.

[0020] Optionally, the material spreading assembly includes a rotating cylinder, a screw and a material spreading gear threadedly connected to the screw, the rotating cylinder is rotatably connected to the lifting plate, the material spreading gear is provided on the rotating cylinder, and the material spreading drive assembly is used to drive the plurality of material spreading gears to rotate;

[0021] The screw is rotatably connected to the material spreading plate, and one end of the screw away from the material spreading plate slides through the lifting plate.

[0022] By adopting the above technical solution, several spreading gears are driven to rotate simultaneously through the spreading drive assembly, thereby driving several screws to move toward or away from the bar material at the same time. When the screw moves toward the bar material, the spreading plate pushes the bar material, causing the bar material to fall onto the loading rack.

[0023] Optionally, the material spreading drive assembly includes a material spreading drive motor, a drive gear and an annular rack. The material spreading drive motor is arranged on the lifting plate, and the drive gear is arranged on the output shaft of the material spreading drive motor. The drive gear is engaged with one of the material spreading gears, and the annular rack is engaged with several of the material spreading gears at the same time.

[0024] By adopting the above technical solution, the spreading drive motor rotates the drive gear, which in turn drives the spreading gear meshing with the drive gear. Consequently, the ring rack drives the multiple spreading gears to rotate synchronously, allowing the multiple screws to simultaneously push the spreading plate. This results in a more even force applied to the bars when the spreading plate pushes them, thus reducing the uneven force applied to the bars, which could cause them to tilt and prevent them from landing on the loading rack. Alternatively, the bars could be caused to deviate from their trajectory as they continue to roll after landing on the loading rack.

[0025] Optionally, the flipping device includes a flipping frame, a rotating rod and a flipping drive motor for driving the rotating rod to rotate, the flipping drive motor is arranged on the frame, the rotating rod is arranged on the flipping frame, and the loading frame is overlapped on the flipping frame.

[0026] By adopting the above technical solution, the turning rod is driven by the flip drive motor to rotate the set angle, the turning rod drives the flip frame to rotate, and the flip frame rotates to drive the loading rack to flip with the hinge between the loading rack and the frame as the center, so that the end of the loading rack away from the conveying rack is higher than the end close to the conveying rack, so that the rods on the loading rack can roll toward the conveying rack under the action of their own gravity and press against the stop block.

[0027] Optionally, the flipping device further includes a reset mechanism and a pair of support mechanisms, the flip frame is located between the pair of support mechanisms, the support mechanism includes a support rod, a rotating shaft and a torsion spring, the rotating shaft is provided on the flip frame, the support rod is rotatably connected to the rotating shaft, the torsion spring is sleeved on the rotating shaft, one end of the torsion spring is provided on the rotating shaft, and the other end of the torsion spring is provided on the support rod;

[0028] The reset mechanism is arranged on the flip frame, and one end of the reset mechanism away from the reset assembly is arranged on the support rod.

[0029] By adopting the above technical solution, the turning drive motor is activated to drive the turning frame to rotate to a certain angle greater than the set rotation angle of the rotating shaft. The reset mechanism is activated to cooperate with the torsion spring, and the support rod rotates under the torsion force of the torsion spring. Then, the turning drive motor is activated to drive the turning frame in reverse, so that the support rod presses against the frame to support the turning frame, thereby ensuring that the turning frame can more stably support the loading rack.

[0030] Optionally, the reset mechanism includes a reset drive motor, a rotating rod, a pair of winding rollers provided on the rotating rod, and a pull rope wound around the winding rollers, one end of the pull rope is provided on the winding rollers, and the other end of the pull rope is provided on the support rod;

[0031] The reset drive motor is arranged on the flip frame, the rotating rod is rotatably connected to the flip frame, and the rotating rod is arranged on the output shaft of the reset drive motor.

[0032] By adopting the above technical solution, the reset drive motor drives the rotating rod to rotate, and the rotation of the rotating rod drives the winding roller to reel in and release the pull rope, so that the support rod can rotate under the action of the torsion spring to support the flip frame or reset the support rod.

[0033] Optionally, the bar turret device includes a material guide frame, a plurality of material ejection cylinders and a material ejection block provided on the driving end of the material ejection cylinder, the material ejection cylinder is provided on the material loading frame, the material ejection block is located on the side of the stop block facing away from the conveying frame and is in contact with the stop block, and the bar is placed on the material ejection block;

[0034] The top surface of the stopper is set as an inclined surface, and the inclined surface of the top surface is set to be inclined downward near one end of the conveying frame. The material guide frame is set on the conveying frame, one end of the material guide frame is located above the feeding device, and the other end of the material guide frame extends to the side of the stopper close to the conveying frame.

[0035] By adopting the above technical solution, a bar is pushed upward by the pushing cylinder so that the lower end of the pushing block is flush with the top of the stopper. Therefore, under the action of the bar's own gravity, the bar rolls to the stopper and the guide rack in turn, and falls onto the feeding device, completing the transfer of the bar from the loading rack to the feeding device.

[0036] Optionally, the material guide rack includes a straight section, an inclined section and a vertical section arranged on the straight section, and a drop hole is provided on the straight section on the side of the vertical section facing the loading rack, and the inclined section extends from one end away from the straight section to the side of the stop block close to the conveying rack.

[0037] By adopting the above technical solution, the bar rolls on the inclined section to the straight section, and under the blocking effect of the vertical section, the bar falls onto the feeding device through the drop hole, completing the transfer of the bar.

[0038] In summary, this application includes at least one of the following beneficial technical effects:

[0039] 1. Compared with manually placing the bars in a row on the loading rack, the use of a spreading device can save the operator's physical strength and improve work efficiency, thereby improving the overall loading efficiency of the entire loading device;

[0040] 2. The turning frame is driven to reverse by the turning drive motor, so that the support rod is pressed against the frame to support the turning frame, so that the turning frame can support the loading rack more stably;

[0051] The following is combined with Figure 1-8 This application is described in further detail.

[0052] The embodiment of the present application discloses an automatic loading device of an automatic bar feeder.

[0053] Reference Figure 1 and Figure 2 The automatic feeding device of the bar material automatic feeder includes a frame 1, a feeding frame 2, a spreading device 8, a turning device 9, a bar material rotating frame device 4, a conveyor frame 3, a feeding device 5, a blocking plate 7, a pair of blocks 6 and a limit plate 10. The conveyor frame 3 and the frame 1 are arranged in a side T-shape. One end of the feeding frame 2 is hinged to the frame 1, and the other end of the feeding frame 2 is overlapped on the turning device 9. The turning device 9 is installed on the frame 1 to drive the feeding frame 2 to rotate. The block 6 is fixed to the end of the feeding frame 2 close to the conveyor frame 3, and the top surface of the block 6 is inclined downward near the end of the conveyor frame 3. The block 6 can block the bar material. A pair of baffles are fixed to the feeding frame 2, and the baffles are arranged in a direction perpendicular to the length of the conveyor frame 3. The bar material is placed on the feeding frame 2 and is located between the pair of limit plates 10. The spreading device 8 is installed at the end of the feeding frame 2 away from the conveyor frame 3. The bar material on the feeding frame 2 is spread flat by the spreading device 8.

[0054] Reference Figure 1 and Figure 2 The feeding device 5 is installed on the conveying frame 3, one end of the bar material rotating rack device 4 is installed on the loading rack 2, and the other end of the bar material rotating rack device 4 is installed on the conveying frame 3.

[0055] Reference Figure 1 and Figure 3 After the whole bundle of bars on the loading rack 2 is flattened by the spreading device 8, the loading rack 2 is rotated by the flipping device 9 so that the loading rack 2 is tilted. Under the action of its own gravity, the bars roll toward the conveying rack 3 and abut against the stopper 6. Under the action of a pair of limit plates 10, the possibility of serious skewness of the bars can be reduced. The bars on the loading rack 2 are transferred one by one to the feeding device 5 through the bar rotating rack device 4, and then the bars are conveyed one by one to the subsequent metal processing equipment through the feeding device 5. Compared with manually placing the bars in a row on the loading rack 2, the use of the spreading device 8 can save the operator's physical strength and improve work efficiency, thereby improving the overall loading efficiency of the entire loading device.

[0056] Reference Figure 2 and Figure 4 The material spreading device 8 includes a material spreading lifting cylinder 81, a lifting plate 82 fixed on the driving end of the material spreading lifting cylinder 81, and a material spreading mechanism 83 installed on the lifting plate 82. The material spreading lifting cylinder 81 is installed on the loading rack 2. The material spreading mechanism 83 can be driven to rise and fall by the material spreading lifting cylinder 81, so that the material spreading mechanism 83 can push rods at different heights.

[0057] Reference Figure 1 and Figure 4The material spreading mechanism 83 includes a material spreading plate 831, a material spreading drive assembly 832, and a plurality of material spreading assemblies 833. In this embodiment, the number of material spreading assemblies 833 is two. The material spreading assembly 833 is composed of a rotating cylinder 8331, a screw 8332, and a material spreading gear 8333 threadedly connected to the screw 8332. The rotating cylinder 8331 is rotatably connected to the lifting plate 82, and the material spreading gear 8333 is coaxially fixed to the end of the rotating cylinder 8331 away from the lifting plate 82. One end of the screw 8332 is rotatably connected to the material spreading plate 831, and the other end of the screw 8332 passes through the rotating cylinder 8331 and slides through the lifting plate 82. The material spreading drive assembly 832 can drive the plurality of material spreading gears 8333 to rotate simultaneously, so that the plurality of screws 8332 can move simultaneously in the direction of approaching or moving away from the bar material.

[0058] In addition, compared to driving the spreading plate 831 to move via a single driving point, the spreading plate 831 may tilt away from the driving point. When the spreading plate 831 pushes the bar stock, the bar stock is prone to uneven force and tilt, preventing the bar stock from landing on the loading rack 2, or the bar stock's movement trajectory may deviate when the bar stock continues to roll after landing on the loading rack 2. Providing multiple screws 8332 to simultaneously push the spreading plate 831 can reduce the possibility of the spreading plate 831 tilting, thereby ensuring that the bar stock is more evenly stressed when the spreading plate 831 pushes the bar stock, allowing the bar stock to land more smoothly on the loading rack 2 and roll down along the loading rack 2.

[0059] Reference Figure 1 and Figure 4 The material spreading drive assembly 832 includes a material spreading drive motor 8321, a drive gear 8322, and an annular rack 8323. The material spreading drive motor 8321 is installed on the side of the lifting plate 82 facing away from the bar material. The drive gear 8322 is coaxially connected to the output shaft of the material spreading drive motor 8321 and is located on the side of the lifting plate 82 facing the bar material. The drive gear 8322 is meshed with one of the material spreading gears 8333. The annular rack 8323 is meshed with several material spreading gears 8333 at the same time. The driving gear 8322 is rotated by the material spreading drive motor 8321, which can drive the material spreading gears 8333 meshed with the driving gear 8322 to rotate. The rotation of the material spreading gear 8333 can drive several pushing gears to rotate synchronously through the annular chain 55, so that several screws 8332 can simultaneously drive the material spreading plate 831 to move, thereby making the force on the bar material more uniform when the material spreading plate 831 pushes the bar material.

[0060] In addition, a baffle plate 7 is fixed to the frame 1 and fits in contact with the baffle plate 7. The baffle plate 7 is located between the stop block 6 and the material spreading device 8. The baffle plate 7 is provided with a feed hole 71 for a single bar to pass through. In this embodiment, the height of the feed hole 71 is 1.5 times the diameter of the bar, so that the feed hole 71 can only pass one bar at a time. Furthermore, under the limiting effect of the feed hole 71, the possibility of a single bar abutting against the stop block 6 can be further increased, so that the bar turret device 4 can transfer one bar at a time to the feed device 5.

[0061] When bars need to be spread, the entire bundle of bars is hoisted onto the steel bar loading rack 2. The spreading lift cylinder 81 is activated to adjust the height of the spreading plate 831, aligning it with the row of bars at the highest horizontal height. The spreading drive motor 8321 is then activated, causing the screws 8332 to simultaneously push the spreading plates 831, causing them to push the bars down onto the loading rack 2. The spreading lift cylinder 81 is then activated to adjust the height of the pusher plate, aligning it with the row of bars at the highest horizontal height. This cycle continues until all bars are aligned with the loading rack 2. The tilting device 9 is then activated, tilting the loading rack 2. This allows the bars to roll under their own weight toward the conveyor rack 3, pass through the feed hole 71, and be transferred one by one to the feed device 5 via the bar turret device 4.

[0062] Reference Figure 1 and Figure 2 The turning device 9 includes a turning frame 91, a rotating rod 92, a turning drive motor 93, a reset mechanism 94, and a pair of support mechanisms 95. The turning drive motor 93 is mounted on the frame 1. The rotating rod 92 is coaxially connected to the output shaft of the turning drive motor 93. The end of the rotating rod 92 away from the turning drive motor 93 is fixed to the turning frame 91, and the end of the loading frame 2 away from the conveyor frame 3 is overlapped on the top surface of the turning frame 91. Therefore, the turning drive motor 93 can drive the turning frame 91 to rotate, causing the loading frame 2 to turn around the hinge between the loading frame 2 and the frame 1, so that the end of the loading frame 2 away from the conveyor frame 3 is higher than the end close to the conveyor frame 3. As a result, the bars on the loading frame 2 can roll toward the conveyor frame 3 under the action of their own gravity and press against the stoppers 6 one by one.

[0063] Reference Figure 2 and Figure 5The flip frame 91 is located between a pair of support mechanisms 95. A reset mechanism 94 is mounted on the flip frame 91 for resetting the support mechanism 95. The support mechanism 95 includes a support rod 951, a rotating shaft 952, and a torsion spring 953. The rotating shaft 952 is fixed to the flip frame 91 and arranged parallel to the length of the conveyor frame 3. One end of the support rod 951 is rotatably connected to the rotating shaft 952. The support rod 951 is provided with a clearance hole. The torsion spring 953 is mounted on the rotating shaft 952 and located in the clearance hole. One end of the torsion spring 953 is fixed to the rotating shaft 952, and the other end of the torsion spring 953 is fixed to the support rod 951. Under the torsion force of the torsion spring 953, the support rod 951 can be driven to rotate in a direction away from the flip frame 91.

[0064] The reset mechanism 94 includes a reset drive motor 941, a rotating rod 942, a pair of winding rollers 943, and a pull rope 944. A mounting plate is fixed to the tilting frame 91, on which the reset drive motor 941 is mounted. The rotating rod 942 is rotatably connected to the tilting frame 91 and coaxially connected to the output shaft of the reset drive motor 941. The pair of winding rollers 943 are coaxially connected to the rotating rod 942, and the tilting frame 91 is located between the pair of winding rollers 943. One end of the pull rope 944 is fixed to the winding rollers 943, and the other end of the pull rope 944 is fixed to the support rod 951. In this embodiment, after the winding rollers 943 completely release the pull rope 944, the support rod 951 is positioned perpendicular to the ground, thereby limiting the support rod 951 and allowing the support rod 951 to more stably support the tilting frame 91, thereby allowing the tilting frame 91 to more stably support the loading rack 2.

[0065] Reference Figure 2 and Figure 4 After the bar material is flattened, the flip drive motor 93 is activated to rotate the flip frame 91 to a certain angle that prevents the bar material from falling off the loading rack 2. The reset drive motor 941 is then activated to rotate the winding roller 943, causing it to release the pull rope 944. The torsion force of the torsion spring 953 drives the support rod 951 to rotate. Under the restraining action of the pull rope 944, the support rod 951 rotates to a position perpendicular to the ground. The flip drive motor 93 is then activated to reverse the flip frame 91, causing the support rod 951 to press against the frame 1, supporting the flip frame 91. This allows the flip frame 91 to more stably support the loading rack 2.

[0066] Reference Figure 3 When the support rod 951 needs to be reset, the reset drive motor 941 is started to drive the winding roller 943 to rotate, so that the winding roller 943 reels the pull rope 944. Under the traction of the pull rope 944, the support rod 951 is reset. Then the flip drive motor 93 is started to drive the flip frame 91 to reset, so that the loading rack 2 is parallel to the ground, so that the whole bundle of steel bars can be lifted and transported to the steel bar loading rack 2.

[0067] Reference Figure 1 、 Figure 6 and Figure 7 The bar turret device 4 includes a guide frame 43, several ejection cylinders 42, and an ejection block 41 provided on the driving end of the ejection cylinder 42. The ejection cylinder 42 is provided on the loading frame 2. The ejection block 41 is located on the side of the stopper 6 facing away from the conveyor frame 3 and is in contact with the stopper 6. The top surface of the ejection block 41 is set as an inclined surface, and a bar is placed on the ejection block 41. The guide frame 43 includes a straight section 431, an inclined section 432, and a vertical section 433. The straight section 431 is located between the inclined section 432 and the vertical section 433, and the inclined section 432 and the vertical section 433 are integrally formed and provided on the straight section 431. A drop hole 4311 is provided on the straight section 431 on the side of the vertical section 433 facing the loading rack 2. The length of the drop hole 4311 is greater than the length of the rod, so that the rod can fall more smoothly. The inclined section 432 extends from one end of the straight section 431 to the side of the stop block 6 close to the conveying rack 3.

[0068] When the loading rack 2 is tilted, the inclined section 432 and the top surface of the baffle have the same inclination angle relative to the ground. The ejection cylinder 42 is activated to push a bar upward, causing the lower end of the ejection block 41 to be flush with the top of the stopper 6. Under the action of the bar's own weight, the bar rolls from the ejection block 41 to the stopper 6, the inclined section 432, and the straight section 431 in sequence. Blocked by the vertical section 433, the bar falls through the drop hole 4311 onto the conveyor 5, completing the transfer of the bar from the loading rack 2 to the conveyor 5.

[0069] Reference Figure 1 、 Figure 7 and Figure 8 The conveying device includes a conveying drive motor 51, a driving sprocket 54 coaxially connected to the output shaft of the conveying drive motor 51, and several feed rollers 52 rotatably connected to the conveyor frame 3. Dual sprockets 53 are mounted on the ends of the feed rollers 52 facing away from the loading frame 2. One of the sprockets 53 at one end is connected to the driving sprocket 54 via a chain 55, while the other sprocket is connected to the corresponding sprocket in the adjacent dual sprocket 53 via a chain 55. The other sprocket in the adjacent dual sprocket 53 is connected to the corresponding sprocket in the adjacent dual sprocket 53 via a chain 55, and so on. Therefore, starting the conveying drive motor 51 drives all the sprockets to rotate simultaneously, which in turn drives all the feed rollers 52 to rotate simultaneously, transporting the bars one by one to the subsequent metal processing equipment.

[0070] The implementation principle of the automatic loading device of the automatic bar feeder of the embodiment of the present application is as follows: when the bars need to be spread, the whole bundle of bars is hoisted onto the steel bar loading rack 2, the spreading lifting cylinder 81 is started to adjust the height of the spreading plate 831 so that the spreading plate 831 is aligned with the row of bars with the highest horizontal height, and then the spreading drive motor 8321 is started so that the plurality of screws 8332 simultaneously push the spreading plate 831 so that the spreading plate 831 pushes the bars onto the loading rack 2. Then the height of the spreading plate 831 is adjusted so that the spreading plate 831 is aligned with the row of bars with the highest horizontal height at this time, and the cycle is repeated so that all the bars are in contact with the loading rack 2. Compared with manually placing the bars in a row on the loading rack 2, the use of the spreading device 8 can save the operator's physical strength and improve work efficiency, thereby improving the overall loading efficiency of the entire loading device.

[0071] The flip drive motor 93 is then started to rotate the flip frame 91 to a certain angle, and the reset drive motor 941 is then started to rotate the winding roller 943, causing the winding roller 943 to release the pull rope 944, causing the support rod 951 to rotate to a position perpendicular to the ground. The flip drive motor 93 is then started to reverse the flip frame 91, causing the support rod 951 to press against the frame 1 to support the flip frame 91. At this time, the loading frame 2 is in an inclined state, and the bars are transferred one by one to the feeding device 5 under the action of their own gravity.

[0072] The push cylinder 42 is activated to push a bar upward, so that the lower end of the push block 41 is flush with the top of the stopper 6. Under the action of the bar's own weight, the bar rolls onto the stopper 6 and the guide rack 43 in sequence, and falls onto the feeding device 5, completing the transfer of the bar from the loading rack 2 to the feeding device 5. After the conveying drive motor 51 is activated, it can drive the various sprockets to rotate simultaneously, and then drive the various feed rollers 52 to rotate simultaneously, conveying the bars one by one to the subsequent metal processing equipment.

[0073] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
