A discharging device for a reinforcing bar sorting machine

Abstract

This utility model discloses a feeding device for a rebar sorting machine, relating to the field of rebar production technology. The feeding device includes a support frame, with a feeding mechanism mounted above the support frame for conveying the rebar discharged from the sorting machine. The feeding mechanism includes a positioning component, comprising a guide tube fixedly installed above the support frame, a drive shaft movably installed below the guide tube, and a drive gear fixedly installed on the outer side of the drive shaft. After the positioning rod is fully loaded with rebar, the notch of the toothed plate first precisely aligns with the notch of the positioning rod and the annular groove of the idler roller. Then, a lifting cylinder drives the toothed plate slowly upward, actively lifting the rebar away from the positioning rod. After the positioning rod resets, the lifting cylinder controls the toothed plate to slowly descend, allowing the rebar to fall smoothly into the annular groove of the idler roller. The annular groove of the idler roller further restricts the lateral displacement of the rebar, ensuring that the rebar falls accurately to the designated position without any inertia-induced deviation throughout the process.

Description

Technical Field

[0001] This utility model relates to the field of steel bar production technology, specifically to a feeding device for a steel bar sorting machine. Background Technology

[0002] The core function of rebar sorting machines is to solve the problem of rebar classification in an automated and precise manner. Their value is not limited to "sorting" itself, but also lies in promoting the transformation of the construction and steel processing industries from "labor-intensive" to "automated and intelligent" by improving efficiency, ensuring accuracy, and reducing costs and risks. They are an indispensable core equipment in the modern rebar processing industry chain.

[0003] The existing utility model patent with announcement number CN207615573U discloses a steel bar cutting and blanking device, belonging to the field of steel processing. Its technical solution is as follows: it includes several fixed columns, a crossbeam connected to the upper end of the fixed columns, a feeding rod set at the lower end of the crossbeam, and a conveying frame set on one side of the fixed columns. Several fixed plates are provided at the upper end of the crossbeam, and a vertical plate is fixedly connected to one end of each fixed plate. An angle steel is provided on the side of the crossbeam near the conveying frame, and each vertical plate is fixedly connected to the angle steel. A sliding plate is slidably connected on the side of the crossbeam near the angle steel. The sliding plate is engaged with the angle steel. A lifting device is provided on the sliding plate, and the lifting device drives the sliding plate to move vertically.

[0004] The synchronization of the multiple actuating plates in the above-mentioned feeding device relies on the rigid connection of the rotating rod. If the rotating rod deforms after long-term use, it will cause some actuating plates to swing at inconsistent angles, and the steel bars will be "stuck in the track gap" or "not moved into place" and unable to enter the groove wheel. At the same time, the above-mentioned feeding device relies on the weight of the steel bars to slide down. During the sliding process, the steel bars may not be able to fall to the designated position due to inertia. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding device for a rebar sorting machine, which solves the problems of inertia affecting the slippage position and rebar jamming.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A feeding device for a rebar sorting machine includes a support frame, and a feeding mechanism is provided above the support frame for conveying the rebar discharged from the sorting machine. The feeding mechanism includes: The positioning assembly includes a guide tube fixedly installed above a support frame, a drive shaft movably installed below the guide tube, a drive gear fixedly installed on the outside of the drive shaft, a fixing plate fixedly installed on one side of the support frame, a drive motor fixedly installed on one side of the fixing plate, a drive groove inserted inside the guide tube, and a positioning rod fixedly installed above the drive groove. A conveying assembly, located on one side of the positioning assembly, is used for lateral conveying of reinforcing bars; The discharge assembly, located on one side of the support frame, is used to limit the steel bars delivered by the conveying assembly.

[0007] Preferably, the conveying assembly includes a limiting shaft fixedly installed on one side of the guide tube, a connecting pipe movably installed on the outer side of the limiting shaft, a synchronous pulley fixedly installed on the outer side of the connecting pipe, a synchronous belt sleeved on the outer side of the synchronous pulley, a conveying motor fixedly installed above the support frame, a bevel gear fixedly installed on the shaft of the conveying motor and on the outer side of the connecting pipe, a limiting frame fixedly installed above the support frame, and an inclined plate movably installed above the limiting frame.

[0008] Preferably, the discharge assembly includes a bracket fixedly installed on one side of the support frame, a roller movably installed above the bracket, a lifting cylinder fixedly installed inside the bracket, and a toothed plate fixedly installed above the lifting cylinder.

[0009] Preferably, the drive shaft and the guide tube are rotatably connected, the bottom of the guide tube is provided with an opening structure, the drive gear is inserted and installed on the outside of the drive shaft and located inside the opening structure of the guide tube, the drive groove is slidably connected with the positioning rod and the guide tube, the bottom of the drive groove is provided with a slot for engaging with the drive gear, the drive gear meshes with the slot at the bottom of the drive groove, and the positioning rod is provided with equidistant triangular notches above it.

[0010] Preferably, the connecting pipe and the limiting shaft form a rotatable connection, the synchronous pulley is installed on one side of the guide pipe through the connecting pipe, the horizontal structure above the synchronous belt is located above the top surface of the guide pipe, the front side of the limiting frame is provided with a vertical structure to limit the rotation angle of the inclined plate, the inclined plate and the limiting frame form a rotatable connection, a counterweight structure is provided below the front end of the inclined plate, and the rear end of the inclined plate is located above the top horizontal structure of the synchronous belt.

[0011] Preferably, the idler roller and the bracket form a rotatable connection, the surface of the idler roller is provided with an array of annular grooves with the same spacing as the positioning rod groove structure, the toothed plate is installed between the idler rollers by a lifting cylinder, and the top of the toothed plate is provided with an array of notches with the same spacing as the notch structure above the positioning rod.

[0012] Beneficial effects This utility model provides a feeding device for a rebar sorting machine. Compared with the prior art, it has the following advantages: (1) The material feeding device of the rebar sorting machine uses a lifting cylinder as a power source in the material discharge assembly, which can drive the toothed plate to achieve smooth lifting and lowering. When the positioning rod is full of rebar, the notch of the toothed plate will first be precisely aligned with the notch of the positioning rod and the annular groove of the roller. Then the lifting cylinder drives the toothed plate to slowly rise, actively lifting the rebar away from the positioning rod, avoiding the rebar from accelerating due to inertia during its own weight. After the positioning rod is reset, the lifting cylinder controls the toothed plate to slowly descend, so that the rebar falls smoothly into the annular groove of the roller. The annular groove of the roller can further restrict the lateral displacement of the rebar, ensuring that the rebar falls accurately to the designated position, and there is no offset problem caused by inertia throughout the process.

[0013] (2) In the material feeding device and positioning component of the rebar sorting machine, the guide tube can strictly limit the sliding path of the transmission groove and the positioning rod, ensuring that the notch of the positioning rod is always accurately aligned with the rebar inlet end of the guide tube and the conveying end of the synchronous belt, avoiding the rebar from failing to enter the notch due to positioning deviation; at the same time, the speed at which the transmission motor drives the positioning rod to move through the transmission shaft and transmission gear is coordinated with the speed at which the conveying motor drives the synchronous belt to convey the rebar through the bevel gear and synchronous wheel, so that the positioning rod only receives one rebar at a time, preventing multiple rebars from accumulating in the notch and causing jamming. In addition, during the conveying process, the inclined plate maintains a stable tilt state due to its own counterweight and the limitation of the limit frame, which can guide the rebar to slide smoothly towards the notch of the positioning rod, avoiding the rebar end from colliding with the synchronous belt and causing offset and jamming. Through the cooperation of multiple links, the problem of rebar jamming is completely solved. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a feeding device for a rebar sorting machine includes a support frame 1, and a feeding mechanism 2 is provided above the support frame 1 for conveying the rebar discharged by the sorting machine. The feeding mechanism 2 includes: a positioning component 21, including a guide tube 211 fixedly installed above the support frame 1, a drive shaft 212 movably installed below the guide tube 211, a drive gear 213 fixedly installed on the outer side of the drive shaft 212, a fixing plate 214 fixedly installed on one side of the support frame 1, a drive motor 215 fixedly installed on one side of the fixing plate 214, and a drive gear 213 inserted inside the guide tube 211. The transmission groove 216 has a positioning rod 217 fixedly installed above it. The transmission shaft 212 and the guide tube 211 are rotatably connected. The bottom of the guide tube 211 is provided with an opening structure. The transmission gear 213 is inserted and installed on the outside of the transmission shaft 212 and is located inside the opening structure of the guide tube 211. The transmission groove 216 is slidably connected with the positioning rod 217 and the guide tube 211. The bottom of the transmission groove 216 is provided with a slot for engaging with the transmission gear 213. The transmission gear 213 meshes with the slot at the bottom of the transmission groove 216. The positioning rod 217 is provided with equidistant triangular notches above it.

[0017] Specifically, the guide tube 211 can restrict the position of the transmission groove 216 and the positioning rod 217. One end of the guide tube 211 is provided with a downwardly sloping plate structure so that the steel bar can roll into the groove of the positioning rod 217. The transmission motor 215 can drive the transmission shaft 212 to rotate, thereby driving the transmission gear 213 to rotate. The transmission gear 213 is engaged with the groove at the bottom of the transmission groove 216 to drive the transmission groove 216 to move the positioning rod 217. By matching the rotation speed of the positioning rod 217 with that of the synchronous belt 224, the positioning rod 217 moves after receiving a steel bar, so that the next groove is located at the bottom end of the inclined plate at the front end of the guide tube 211.

[0018] The conveying assembly 22, located on one side of the positioning assembly 21, is used for lateral conveying of reinforcing bars. The conveying assembly 22 includes a limiting shaft 221 fixedly installed on one side of the guide tube 211. A connecting tube 222 is movably installed on the outer side of the limiting shaft 221. A synchronous pulley 223 is fixedly installed on the outer side of the connecting tube 222. A synchronous belt 224 is sleeved on the outer side of the synchronous pulley 223. A conveying motor 225 is fixedly installed above the support frame 1. A bevel gear 226 is fixedly installed on the shaft of the conveying motor 225 and on the outer side of the connecting tube 222. A limiting frame 227 is fixedly installed above the support frame 1. An inclined plate 228 is movably installed above the limiting frame 227. A connecting pipe 222 and a limiting shaft 221 are rotatably connected. A synchronous pulley 223 is installed on one side of the guide pipe 211 through the connecting pipe 222. A horizontal structure above the synchronous belt 224 is located above the top surface of the guide pipe 211. A vertical structure is provided on the front side of the limiting frame 227 to limit the rotation angle of the inclined plate 228. A rotatable connection is formed between the inclined plate 228 and the limiting frame 227. A counterweight structure is provided below the front end of the inclined plate 228. The rear end of the inclined plate 228 is located above the top horizontal structure of the synchronous belt 224.

[0019] Specifically, the limiting shaft 221 can limit the position of the connecting pipe 222, the connecting pipe 222 can limit the position of the synchronous pulley 223, the synchronous pulley 223 can tighten the synchronous belt 224, and the synchronous pulley 223 is driven to rotate by the conveying motor 225 and the bevel gear 226, thereby conveying the steel bar above the guide pipe 211 to the position rod 217. The inclined plate 228 can maintain an inclined state under the restriction of the front counterweight and the front vertical structure of the limiting frame 227, preventing the end of the steel bar from contacting one side of the synchronous belt 224 and damaging the synchronous belt 224 during the movement of the steel bar.

[0020] The discharge assembly 23 is disposed on one side of the support frame 1 to restrict the steel bars delivered by the conveying assembly 22. The discharge assembly 23 includes a bracket 231 fixedly installed on one side of the support frame 1. A roller 232 is movably installed above the bracket 231. A lifting cylinder 233 is fixedly installed inside the bracket 231. A toothed plate 234 is fixedly installed above the lifting cylinder 233. The roller 232 and the bracket 231 are rotatably connected. The surface of the roller 232 is provided with an annular groove array with the same spacing as the groove structure of the positioning rod 217. The toothed plate 234 is installed between the rollers 232 through the lifting cylinder 233. The top of the toothed plate 234 is provided with a notch array with the same notch structure and spacing as the notch structure above the positioning rod 217.

[0021] Specifically, after each slot above the positioning rod 217 receives a reinforcing bar, the notch of the positioning rod 217 is aligned with the notch of the toothed plate 234 and the groove of the roller 232. The lifting cylinder 233 drives the toothed plate 234 to move upward, lifting all the reinforcing bars above the positioning rod 217. Then the positioning rod 217 is reset to receive the reinforcing bars again. Finally, the lifting cylinder 233 retracts, causing the reinforcing bars to fall into the groove of the roller 232. Meanwhile, all contents not described in detail in this specification are prior art known to those skilled in the art.

[0022] During operation, after the sorting machine discharges the reinforcing bars, the bars first contact the inclined plate 228 above the limiting frame 227 (this inclined plate is located between adjacent guide tubes 211). Because there is a counterweight structure below the front end of the inclined plate 228, and there is a vertical structure on the front side of the limiting frame 227 that restricts its rotation angle, the inclined plate 228 always maintains a stable tilted state. Furthermore, the rotation center of the inclined plate 228 is lower than the top horizontal structure of the synchronous belt 224. Under its guidance, the reinforcing bars smoothly cross the synchronous belt 224 (the horizontal structure above the synchronous belt 224 is located above the top surface of the guide tube 211), and after the reinforcing bars cross the synchronous belt 224, they are supported by the weight of the reinforcing bars. Under the influence of the quantity, the steel bar rotates to a near-horizontal state so that it can finally fall above the guide pipe 211. Then, the conveyor motor 225 above the support frame 1 starts, and the bevel gear 226 on the outside of its rotating shaft meshes with the bevel gear 226 on the outside of the connecting pipe 222 for transmission. The connecting pipe 222 is movably installed on the outside of the limiting shaft 221 on one side of the guide pipe 211. Driven by the bevel gear 226, the connecting pipe 222 rotates around the limiting shaft 221, which in turn drives the synchronous pulley 223 on its outside to rotate. The synchronous pulley 223 drives the synchronous belt 224 sleeved on the outside to rotate through its own rotation. During the rotation of the synchronous belt 224... The reinforcing bars above the guide tube 211 are conveyed towards the positioning rod 217; simultaneously, the drive motor 215 on one side of the fixed plate 214 starts, driving the drive shaft 212 movably installed below the guide tube 211 to rotate. The drive gear 213 on the outside of the drive shaft 212 (located in the opening structure at the bottom of the guide tube 211) rotates accordingly. Because the drive gear 213 meshes with the bottom groove of the drive groove 216, it can drive the drive groove 216 inserted inside the guide tube 211 to drive the positioning rod 217 above it to slide along the guide tube 211. The moving speed of the positioning rod 217 matches the conveying speed of the synchronous belt 224, ensuring... The reinforcing bars conveyed by the synchronous belt 224 can fall precisely into the equidistant triangular notches of the positioning rod 217, completing the conveying process of the reinforcing bars to the positioning rod 217. After all the notches of the positioning rod 217 have received the reinforcing bars, the positioning rod 217 continues to move until the notches of the positioning rod 217 are precisely aligned with the annular groove of the roller 232 above the bracket 231 and the notch of the toothed plate 234. Finally, the lifting cylinder 233 drives the toothed plate 234 to lift the reinforcing bars upward. Then the positioning rod 217 resets and continues to receive new reinforcing bars. The lifting cylinder 233 retracts, causing the reinforcing bars to fall into the annular groove of the roller 232, thus completing the unloading process.
