Description

Technical Field

[0001] This invention relates to the field of testing technology for building steel reinforcement production, and in particular to a laser measuring device for the straightness of building steel reinforcement. Background Technology

[0002] In the field of construction engineering, steel bars are an indispensable main structural material. The straightness of steel bars directly affects the safety and stability of the entire building. The straightness of steel bars refers to their straightness in the length direction. This indicator is crucial to ensuring that steel bars can be evenly stressed and effectively bear loads in concrete structures. If steel bars have problems such as bending or deformation, it will cause stress concentration when they are under stress, which will affect the overall strength and durability of the structure. Therefore, strictly controlling the straightness of steel bars is an important prerequisite for ensuring the quality of construction projects and ensuring the safety and reliability of buildings during use.

[0003] Existing methods for handling piles of steel bars for testing face the challenge of sorting. Due to the large quantity of steel bars piled up, workers need to manually separate them one by one, which is not only physically and time-consuming but also extremely inefficient. This means that sorting hundreds or thousands of steel bars often requires multiple people to work together, severely slowing down the testing progress. At the same time, manual sorting makes it difficult to ensure that the steel bars are arranged neatly, and the position of the steel bars needs to be readjusted for subsequent testing. It is also impossible to effectively automate the feeding and inspection of the steel bars to be tested before unloading. This makes each test of steel bars require tedious and time-consuming preparation work, greatly increasing the testing cost. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing technology has the disadvantage that it is not conducive to the individual detection of steel bars when they are placed in a pile, and the degree of automation of the detection process is insufficient. To this end, we propose a laser measurement device for the straightness of building steel bars.

[0005] To achieve the above objectives, this application adopts the following technical solution: a laser measuring device for the straightness of building steel bars, comprising a housing, a movable inclined plate installed inside the housing, an inclined guide shell fixedly connected to one side of the housing, a receiving shell provided on one side of the inclined guide shell, a plurality of sets of arc plates provided inside the receiving shell, each set of arc plates having three arc plates, a cross plate provided inside the inclined guide shell, and also including a clamping plate. The receiving shell is equipped with an arrangement mechanism to make the arc plate rotate continuously, arrange the piled steel bars, and transport the steel bars forward to the detection area. The top of the shell is fixedly connected to the body of a laser measuring device, and the surface of the steel bars is scanned by the laser measuring device to make measurements. The conveying mechanism is installed at the front end of the inclined guide shell so that after the two clamping plates move to the discharge port of the inclined guide shell, the clamping plate near the cross plate rises, so that the steel bar rolls into the space between the two clamping plates, and then the clamping plates clamp the steel bar and convey it forward. An anti-blocking mechanism is connected to the conveying mechanism so that the clamping plate moves closer to the inclined guide shell, causing the cross plate to rotate and guide the steel bars inside the inclined guide shell out one by one. The feeding mechanism is connected to the anti-blocking mechanism. After the steel bar detection is completed, the moving inclined plate moves backward, causing the steel bar to fall from the top of the moving inclined plate. The moving inclined plate automatically resets when the clamping plate gradually approaches the moving inclined plate.

[0006] Preferably, the arrangement mechanism includes: A guide plate is installed on the inner wall of the receiving shell. The surface of the guide plate has three long grooves. Two first gears are installed on both sides of the inner wall of the receiving shell. The surfaces of the two first gears are meshed with a toothed chain. Several long rods are fixedly connected between the two toothed chains. Several sets of arc plates are fixedly connected to the surfaces of the several long rods. A motor is fixedly connected to one side of the receiving shell. The output end of the motor is fixedly connected to one side of the first gear. A storage shell is fixedly connected to the top of the inclined guide shell. The top of the storage shell has three staggered grooves.

[0007] Preferably, the conveying mechanism includes: A sliding groove is formed on both sides of a housing. A laser measuring device body is fixedly connected to the top of the housing, and a bracket is also fixedly connected to the top of the housing. A lead screw is installed on the bracket and the laser measuring device body. A motor is fixedly connected to one side of the bracket, and the output end of the motor is fixedly connected to the lead screw. A sliding table is mounted on the surface of the lead screw. A sliding plate is slidably connected to the inner wall of the sliding groove. Both ends of the sliding plate are rotatably connected to rotating plates via rotating shafts. The end of the rotating plate away from the sliding plate is slidably connected to the inner wall of the sliding groove. Both ends of one side of the sliding plate are rotatably connected to a disc via rotating shafts. The end of the rotating plate away from the sliding plate is fixedly connected to the surface of the disc. A lifting rod is fixedly connected to one side of the disc. A mounting frame is fixedly connected between the two sliding plates. Two clamping plates slide on both sides of the mounting frame. Limiting shells are fixedly connected to both ends of the top of the clamping plates. The lifting rod slides on the inner wall of the limiting shell. Both sides of the sliding table are fixedly connected to the surface of the sliding plate via extension plates.

[0008] Preferably, the anti-blocking mechanism includes: The set includes four limiting shells, which are fixedly connected to both sides of the housing. A guide plate is slidably connected between two of the limiting shells. A toothed plate is fixedly connected to the bottom of the guide plate. A second gear is fixedly connected to both ends of the cross plate. One side of the toothed plate meshes with the surface of the second gear. A sliding rod is fixedly connected to one side of the two rotating plates. The sliding rod is slidably connected to the inner wall of the guide plate.

[0009] Preferably, the feeding mechanism includes: The limiting plates are four in number and evenly distributed on both sides of the housing. An outer frame plate is slidably connected to the surface of the limiting plates. The front end of the movable inclined plate is fixedly connected to the outer frame plate. The limiting plates slide through the front end of the housing. Toothed grooves are provided on both sides of the limiting plates. A third gear is fixedly connected to both ends of the cross plate. The top of the toothed groove is meshed with the surface of the third gear.

[0010] Preferably, a stationary inclined plate is fixedly connected inside the shell, the slope of the stationary inclined plate is equal to the slope of the moving inclined plate, and the stationary inclined plate and the moving inclined plate form a V-shaped structure.

[0011] Preferably, a circular groove is provided in the middle of the cross plate, and the interior of the inclined guide shell is embedded in the inner wall of the circular groove by a protrusion.

[0012] Preferably, the inside of the receiving shell is fixedly connected to an inner lining plate, which is placed on the inner wall of several long rods.

[0013] The technical effects and advantages of this invention are as follows: In this invention, after the steel bars are moved one by one to the detection area, the laser measuring device emits a laser beam to irradiate the steel bars, forming a bright straight line on their surface. The shape of this straight line reflects the straightness of the steel bar. The device uses a high-sensitivity photoelectric sensor to accurately capture the minute deformation of the laser line, convert it into an electrical signal for processing, and the built-in microprocessor analyzes and calculates the signal to quickly obtain the straightness data of the steel bar and display it on the display screen. The operator can intuitively understand the situation and provide a basis for subsequent construction or correction.

[0014] In this invention, the first gear and gear chain are driven by a motor to rotate, which drives the arc plate on the long rod to rotate in a ring. This lifts up the steel bars piled up in the receiving shell one by one and transports them to the inclined guide shell, realizing the automatic arrangement and feeding of steel bars. There is no need for manual sorting, which greatly improves the efficiency and neatness of steel bar feeding and provides strong support for subsequent individual steel bar testing.

[0015] In this invention, a motor drives a lead screw to move a sliding table and a sliding plate along a chute. When the sliding plate reaches the rear end, components such as a rotating plate move together to raise the clamping plate to receive the reinforcing bar. The lead screw rotates in the opposite direction to lower the clamping plate, clamp the reinforcing bar, and move it forward. When it reaches the detection area, the front clamping plate moves up to release the reinforcing bar, completing the conveying process. This process achieves precise and orderly conveying of the reinforcing bar from the discharge port to the detection area, ensuring that only one reinforcing bar is conveyed at a time, avoiding chaos and blockage during the conveying process. At the same time, it can work in conjunction with other mechanisms, improving the overall automation level and detection efficiency of the equipment, and reducing the workload of the operators.

[0016] In this invention, a motor drives a lead screw to move the slide table, which in turn moves the sliding plate and clamping plate. When the clamping plate approaches the inclined guide shell, the anti-blocking mechanism is linked to the rotation of the cross plate, which guides the steel bars one by one to the space between the clamping plates. Then, the clamping plates hold the steel bars and transport them to the testing area, ensuring that only one steel bar is guided out at a time, avoiding blockage and ensuring the orderliness of the testing process.

[0017] In this invention, after the inspection is completed, the anti-blocking mechanism, in conjunction with the feeding mechanism, moves the inclined plate backward, causing the steel bar to fall from the V-shaped area. The automatic feeding and equipment reset after the steel bar inspection is completed do not require manual operation, reducing human intervention, improving the overall working efficiency and automation level of the equipment, and ensuring the continuity of the inspection process.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0021] Reference Figure 1 - Figure 8 As shown, the present invention provides a technical solution: a laser measuring device for the straightness of building steel bars, including a housing 1, a movable inclined plate 2 installed inside the housing 1, an inclined guide shell 3 fixedly connected to one side of the housing 1, a receiving shell 4 provided on one side of the inclined guide shell 3, a plurality of sets of arc plates 5 provided inside the receiving shell 4, each set of arc plates 5 having three, a cross plate 6 provided inside the inclined guide shell 3, and also includes a clamping plate 7. The receiving shell 4 has an internal arrangement mechanism, the conveying mechanism is installed at the front end of the inclined guide shell 3, the anti-blocking mechanism is connected to the conveying mechanism, and the unloading mechanism is connected to the anti-blocking mechanism.

[0022] Reference Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, in this embodiment, the arrangement mechanism includes: A guide plate 8 is installed on the inner wall of the receiving shell 4. Three long grooves 9 are formed on the surface of the guide plate 8. Two first gears 10 are installed on both sides of the inner wall of the receiving shell 4. A toothed chain 11 is connected to the surfaces of the two first gears 10 through meshing. Several long rods 12 are fixedly connected between the two toothed chains 11. Several sets of arc plates 5 are fixedly connected to the surfaces of the long rods 12. A motor 14 is fixedly connected to one side of the receiving shell 4. The output end of the motor 14 is fixedly connected to one side of the first gear 10. A receiving shell 15 is fixedly connected to the top of the inclined guide shell 3. Three staggered grooves 16 are formed on the top of the receiving shell 15. Workers place bundles of steel bars inside the receiving shell 4. The guide plate 8 guides the steel bars obliquely towards the arc plates 5. Then, the motor 14 is started, driving the first gears 10 to rotate and meshing with the toothed chains 11. The movement causes the toothed chain 11 to make a clockwise circular motion. During this process, the long rod 12 and the arc plate 5 rotate clockwise in sync. Because the reinforcing bars are guided to the side near the arc plate 5 by the guide plate 8, they accumulate in the top area of ​​the arc plate 5 located at the bottom left. As the toothed chain 11 continues to rotate, the arc plate 5 follows the long rod 12 to rotate clockwise and rise, emerging from the inside of the accumulated reinforcing bars. The arc-shaped groove at the top of the arc plate 5 matches the round rod structure of the reinforcing bars, so that each time the arc plate 5 rises from the pile of reinforcing bars, it can lift a reinforcing bar with its arc-shaped concave shape, and drive the reinforcing bars to move upward in a circular motion with the continuous operation of the toothed chain 11. The concave size of the arc plate 5 can only accommodate one reinforcing bar, which can prevent the arc plate 5 from lifting too many reinforcing bars on one side. The opening of the long groove 9 allows the arc plate 5 to be placed in it and move, further ensuring that the position of the arc plate 5 is at the bottom of the accumulated reinforcing bars under the guidance of the guide plate 8. After the arc plate 5 lifts the reinforcing bar and rotates it to the top area of ​​the toothed chain 11, it gradually deflects downwards. After the arc plate 5 deflects and tilts, the reinforcing bar will fall off its surface. At this time, the arc plate 5 has rotated to the other side of the top of the toothed chain 11. The fallen reinforcing bar will enter the receiving shell 15. The top area of ​​the receiving shell 15 is in contact with one side of the toothed chain 11. The arc plate 5 can slide through the staggered groove 16 to avoid obstructing movement, ensuring that the reinforcing bar can accurately enter the receiving shell 15. Then, the inclined guide shell 3 and the conveying mechanism cooperate to carry out subsequent laser measurement. With the help of the arc plate 5, the reinforcing bars are conveyed in batches, and after the reinforcing bars are neatly arranged, they enter the receiving shell 15, thereby completing the sorting and conveying of the accumulated reinforcing bars. This allows the reinforcing bars to enter the receiving shell 15 and flow to the inclined guide shell 3 for subsequent testing. There is no need for staff to manually sort and place the accumulated reinforcing bars, ensuring the automation and efficiency of the testing process.

[0023] Reference Figure 1 - Figure 6 As shown, in this embodiment, the conveying mechanism includes: A slide groove 17 is formed on both sides of the housing 1. A laser measuring device body 18 is fixedly connected to the top of the housing 1. A bracket 19 is fixedly connected to the top of the housing 1. A lead screw 20 is installed on the bracket 19 and the laser measuring device body 18. A motor 21 is fixedly connected to one side of the bracket 19. The output end of the motor 21 is fixedly connected to the lead screw 20. A slide table 22 is installed on the surface of the lead screw 20. A sliding plate 23 is slidably connected to the inner wall of the slide groove 17. Both ends of the sliding plate 23 are rotatably connected to a rotating plate 24 via a rotating shaft. The end of the rotating plate 24 away from the sliding plate 23 is slidably connected to the inner wall of the slide groove 17. Both ends of one side of the sliding plate 23 are rotatably connected to a disc 25 via a rotating shaft. One end away from the sliding plate 23 is fixedly connected to the surface of the disc 25. A lifting rod 26 is fixedly connected to one side of the disc 25. A mounting frame 27 is fixedly connected between the two sliding plates 23. Two clamping plates 7 slide on both sides of the mounting frame 27. Limiting shells 28 are fixedly connected to both ends of the top of the clamping plates 7. The lifting rod 26 slides on the inner wall of the limiting shell 28. The two sides of the slide table 22 are fixedly connected to the surface of the sliding plate 23 through extension plates. Since the reinforcing bars have been transported into the receiving shell 15 by the arc plate 5, with the inclination of the inner wall of the inclined guide shell 3, the reinforcing bars that roll into the inclined guide shell 3 from the receiving shell 15 gradually roll towards the discharge port of the inclined guide shell 3. Through the operation of the limiting mechanism, these reinforcing bars will not roll out of the inclined guide shell 3. Instead of being discharged inside the guide housing 3, the waste is stored inside the inclined guide housing 3. Then, the motor 21 operates, causing the lead screw 20 to rotate, which in turn causes the slide table 22 to move back and forth along the surface of the lead screw 20. The direction of movement of the slide table 22 depends on the rotation direction of the lead screw 20. For example, when the lead screw 20 is initially close to the laser measuring device body 18, as the slide table 22 moves backward, it causes the sliding plate 23 to slide backward along the slide groove 17. At this time, one end of the rotating plate 24 also slides in the slide groove 17. When the sliding plate 23 slides to the rear end of the slide groove 17, the rotating plate 24 gradually enters the inclined groove at the rear end of the slide groove 17, causing one end of the rotating plate 24 to begin to deflect upward along the slide groove 17. The movement causes the rotating plate 24 to drive the disc 25 to rotate around one end of the sliding plate 23. Through this process, the disc 25 deflects clockwise by a certain angle, thereby changing the height of the lifting rod 26 and raising its position. The lifting rod 26 slides inside the limiting shell 28. When it rotates and rises with the disc 25, the lifting rod 26 slides inside the limiting shell 28 and pushes the limiting shell 28 upward a certain distance. This causes the clamping plate 7 to slide upward a certain distance along one side of the mounting frame 27. This process raises the position of the clamping plate 7 near the left side and releases the limiting mechanism, allowing a steel bar inside the inclined guide shell 3 to slide out along the inclined angle of the inclined guide shell 3 to its outlet. When the two clamping plates 7 are located at the exit of the inclined guide shell 3, and the height of the left clamping plate 7 is raised, this allows the reinforcing bars to enter between the two clamping plates 7, such as... Figure 4As shown, the lead screw 20 and the slide table 22 move in opposite directions, causing the sliding plate 23 to start moving in the opposite direction. The rotating plate 24 slides out of the inclined groove of the slide 17 and enters the straight groove. This causes the lifting rod 26 to deflect and reset in the opposite direction, driving the clamping plate 7 to descend in height, so that the two clamping plates 7 are in a closed state, clamping the steel bar between the two clamping plates 7. After that, the slide table 22 continues to move forward, driving the sliding plate 23 to move in a straight line along the inside of the slide 17. During this process, the mounting frame 27 moves in a straight line with the sliding plate 23, realizing that the two clamping plates 7 clamp the steel bar and move forward. When the sliding plate 23 moves to the front end position of the slide 17, the rotating plate 24 near the front end will slide into the front inclined groove of the slide 17, causing the clamping plate 7 near the front end to start moving upward. At this time, the two clamping plates 7 will be in the top area of ​​the stationary inclined plate 38. As the front clamping plate 7 moves upward, the reinforcing bar is no longer restricted by the clamping plate 7, and can then slide downward between the static inclined plate 38 and the moving inclined plate 2. At this time, the static inclined plate 38 and the moving inclined plate 2 are in a closed state, forming a detection area. The reinforcing bar will roll along the slope of the static inclined plate 38 to the bottom of the laser measuring device body 18. Subsequently, the laser measuring device body 18 is activated, irradiating the reinforcing bar with a laser beam. The laser beam forms a bright straight line on the surface of the reinforcing bar. The shape of this straight line directly reflects the straightness of the reinforcing bar. The device is equipped with a high-sensitivity photoelectric sensor, which can accurately capture the minute deformation of the laser line and convert it into an electrical signal for processing. Through the micro-sensor built into the laser measuring device body 18... The processor analyzes and calculates these signals to quickly obtain the straightness data of the reinforcing bars and displays the results on the device's screen. This allows operators to intuitively understand the straightness of the reinforcing bars, providing a valuable basis for subsequent construction or correction work. During the inspection process, after the conveying mechanism places the reinforcing bars into the inclined plate 2, the conveying mechanism will run again to prepare for the next material feeding and conveying. This allows the inspection and conveying mechanisms to operate simultaneously, improving the inspection efficiency of the device. The entire inspection process requires almost no manual intervention. Operators only need to set the parameters and start the equipment, and the equipment can automatically complete a series of actions such as conveying, clamping, moving, and inspecting the reinforcing bars, greatly reducing the workload of operators.

[0024] Reference Figure 1 - Figure 6 As shown in this implementation plan, the anti-blocking mechanism includes: Four limiting shells 28 are fixedly connected to both sides of the housing 1. A guide plate 29 is slidably connected between two limiting shells 28. A toothed plate 30 is fixedly connected to the bottom of the guide plate 29. Second gears 31 are fixedly connected to both ends of the cross plate 6. One side of the toothed plate 30 meshes with the surface of the second gear 31. Sliding rods 36 are fixedly connected to one side of each of the two rotating plates 24. The sliding rods 36 are slidably connected to the inner wall of the guide plate 29. When the clamping plate 7 approaches the discharge port of the inclined guide housing 3... When the rotating plate 24 deflects through the inclined groove of the clamping plate 7, the sliding rod 36 rises in height along with the deflection of the rotating plate 24. Since the sliding rod 36 slides inside the guide plate 29, and the guide plate 29 slides inside the limiting shell 28, when the position of the sliding rod 36 is raised, it will also push the guide plate 29 upward by a certain distance. Through the meshing of the toothed plate 30 and the second gear 31, the toothed plate 30 pushes the second gear 31 to rotate counterclockwise by ninety degrees, and the cross plate 6 will also rotate synchronously with the second gear 31. Since the reinforcing bars are stored in the inclined guide shell... The steel bars are arranged horizontally inside the inclined guide shell 3. Due to the height of the interior of the inclined guide shell 3, there is no accumulation. This allows the foremost end of the steel bars inside the inclined guide shell 3 to contact the cross plate 6 located inside the inclined guide shell 3. The steel bars are restricted by the cross plate 6 and cannot move forward. When the cross plate 6 rotates 90 degrees counterclockwise, the foremost steel bar is no longer restricted by the cross plate 6 and will slide forward a distance. This allows the cross plate 6 to discharge one steel bar when it rotates 90 degrees. Subsequent steel bars will be continuously restricted by the rotating cross plate 6 and cannot move forward. That is, when the clamping plate 7 near the rear end rises once, the cross plate 6 will rotate once to discharge a steel bar. When the rear clamping plate 7 moves forward and returns to its original position, the cross plate 6 will also return to its original position and rotate in the opposite direction, pushing the steel bars inside the inclined guide shell 3 backward. During this process, the steel bars are restricted by the rotation of the inner wall of the inclined guide shell 3 and are not affected. This allows the device to discharge one steel bar for testing each time it runs, avoiding blockage and accumulation caused by the steel bars after they are arranged, so as to ensure the quantity of steel bars delivered by the clamping plate 7 each time, thereby ensuring the accuracy and efficiency of the measurement.

[0025] Reference Figure 1 - Figure 6 As shown in this implementation scheme: the feeding mechanism includes: Four limiting plates 32 are evenly distributed on both sides of the housing 1. An outer frame plate 33 is slidably connected to the surface of each limiting plate 32. The front end of the movable inclined plate 2 is fixedly connected to the outer frame plate 33. The limiting plates 32 slide through the front end of the housing 1. Toothed grooves 34 are provided on both sides of each limiting plate 32. A third gear 35 is fixedly connected to both ends of the cross plate 6. The top of the toothed groove 34 meshes with the surface of the third gear 35. When the clamping plate 7 is at the discharge port of the inclined guide housing 3 for feeding, the guide plate 29 rises with the sliding rod 36, causing the second gear 31 to rotate. This causes the third gear 35 to rotate counterclockwise, moving the outer frame plate 33 backward along the limiting plate 32, and subsequently moving the movable inclined plate 2 forward. This causes the stationary inclined plate 38 to separate from the movable inclined plate 2. The reinforcing bars previously fed between the stationary inclined plate 38 and the movable inclined plate 2 for testing will also be separated from the movable inclined plate 2 through this gap. The steel bars fall downwards and are discharged from inside the housing 1. Workers can set up a conveyor belt or a collection box at the bottom between the stationary inclined plate 38 and the moving inclined plate 2 to collect, guide, and transport the inspected steel bars to the next processing step. When the clamping plate 7 descends, the third gear 35 and the second gear 31 will rotate again to reset and move. This causes the third gear 35 to drive the tooth groove 34 to move the outer frame plate 33 backward, which in turn pulls the moving inclined plate 2 backward to move closer to the stationary inclined plate 38, closing the gap between the two. Subsequently, the conveying mechanism transports new steel bars to the stationary inclined plate 38 for inspection, so as to realize automatic unloading after the steel bar inspection is completed, without manual operation, improving the overall work efficiency and automation level of the equipment. If the straightness of the steel bar does not meet the requirements, the laser measuring equipment body 18 will also mark the steel bar through its built-in laser printing mechanism, so that workers can quickly identify and sort out the unqualified steel bars.

[0026] Reference Figure 3 As shown in this embodiment: a stationary inclined plate 38 is fixedly connected inside the housing 1. The slope of the inclined surface of the stationary inclined plate 38 is equal to the slope of the inclined surface of the movable inclined plate 2. The stationary inclined plate 38 and the movable inclined plate 2 form a V-shaped structure. When the steel bar is clamped and transported to the area of ​​the stationary inclined plate 38 and the movable inclined plate 2 by the clamping plate 7, as the clamping plate 7 releases the restriction on the steel bar, the steel bar will roll along the inclined surface of the stationary inclined plate 38 to the bottom of this V-shaped structure. Through this structure, the steel bar is restricted between the stationary inclined plate 38 and the movable inclined plate 2, and will not be in an inclined state during the detection due to its natural fall. This automatically limits the angle of the steel bar during the detection, ensuring that the steel bar is placed at a uniform angle during the detection, and providing strong support for the subsequent detection of the laser measuring equipment body 18.

[0027] Reference Figure 4As shown in this embodiment: a circular groove 37 is provided in the middle of the cross plate 6, and the inside of the inclined guide shell 3 is embedded in the inner wall of the circular groove 37 through the protrusion. Through the cooperation between the protrusion and the circular groove 37 inside the inclined guide shell 3, the reinforcing bars are prevented from being pushed out of the gap between the inclined guide shell 3 and the cross plate 6 when the cross plate 6 rotates clockwise. This ensures that each operation of the cross plate 6 will not have too much impact on the reinforcing bars that slide close to the cross plate 6, thereby ensuring the stability of the reinforcing bars in the inclined guide shell 3 and ensuring the neatness of the reinforcing bars arranged inside the inclined guide shell 3.

[0028] Reference Figure 7 and Figure 8 As shown in this embodiment: the receiving shell 4 is fixedly connected to an inner liner plate 13, which is placed on the inner wall of several long rods 12. The inner liner plate 13 supports the inner wall of the circular running trajectory of the long rods 12 by being placed inside the long rods 12, so that the accumulated steel bars can be restricted by the inner liner plate 13 and cannot move forward. This allows the inclined steel bars to fit against the back side of the inner liner plate 13 and then pick up the material as the arc plate 5 runs, avoiding the steel bars from blocking the circular running trajectory of the arc plate 5 and the long rods 12.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

Claims
