Description

Technical Field

[0001] This invention relates to the field of rebar tying technology, and in particular to an intelligent rebar tying device. Background Technology

[0002] Rebar bundling refers to the process of securely binding a specific quantity of rebars of the same specifications, grade, and shape into a single bundle using specialized binding materials such as high-strength strapping or steel wire, at specified intervals and in a standardized manner after rebar production or processing. This forms a stable unit, preventing scattering, deformation, or slippage during hoisting, transportation, storage, and stacking, thus ensuring operational safety. Each bundle of rebar must be clearly labeled with its specifications, grade, length, quantity, production batch, and project name, ensuring traceability of quality information.

[0003] Intelligent steel bar packaging is an upgraded form of traditional steel bar packaging. It refers to a fully automated and information-based operation process that relies on advanced technologies such as the Internet of Things, industrial robots, machine vision, big data and artificial intelligence to achieve automatic identification, accurate measurement, intelligent binding and digital management of steel bars. Industrial robots or automated special machines are used to replace manual operations to complete the entire process of picking up, aligning, binding and stacking steel bars, thus achieving unmanned production.

[0004] Most existing rebar tying devices can only perform the task of bundling and tying rebars. Subsequent bending or rust removal after the rebars have been exposed to moisture requires additional equipment, which greatly reduces the overall practicality of the device. Summary of the Invention

[0011] Preferably, the surface of the limiting post has three V-shaped grooves arranged sequentially from top to bottom, and three horizontal grooves arranged sequentially from top to bottom. The two ends of each horizontal groove are connected to the two ends of the corresponding V-shaped groove. The three sliding rods are respectively slidably adapted to the three V-shaped grooves and the three horizontal grooves.

[0012] Preferably, each of the V-grooves is formed by two inclined grooves, and the two inclined grooves are symmetrically distributed, wherein the length of the two inclined grooves on the lowermost V-grooves is slightly shorter than that of the inclined grooves on the upper two V-grooves.

[0013] Preferably, the surface of the limiting post is provided with an inclined groove and a horizontal groove II that communicates with the cylindrical rod. The inclined groove communicates with the V-shaped groove at the highest position. An electric baffle is rotatably connected to the connection between the inclined groove and the V-shaped groove. The sliding rod is slidably adapted to the inclined groove and the horizontal groove II.

[0014] Preferably, the surface of the limiting post is provided with a horizontal groove three, the horizontal groove three is interconnected with the V-shaped groove in the middle position, the connection between the horizontal groove three and the V-shaped groove is rotatably connected to an electric baffle two, the slide rod is slidably adapted to the horizontal groove three, the surface of the limiting post is sleeved with a non-complete gear, and the upper end of the inner shaft is fixedly connected to a rectangular block that intermittently meshes with the non-complete gear.

[0016] Compared with the prior art, the present invention provides an intelligent rebar tying device, which has the following beneficial effects:

[0017] The first working mechanism drives two working rods to move downwards, so that the working hole moves below the rebar to be bundled, allowing the wire to pass through the working hole, as shown in the figure. Then, it drives the two working rods to move upwards, so that the wire forms a semi-encirclement around the rebar to be bundled. Next, it drives the two working rods to swing towards each other, forming a closed loop with the wire. Finally, it drives the two working rods to rotate, twisting the two ends of the wire together, thus completing the binding of the rebar.

The second working mechanism drives the two positioning plates to move closer to each other, clamping the steel bars to be bent. Meanwhile, the first working mechanism drives one of the working rods to be horizontal and the other to be vertical. The rotation of the vertical working rod can bend the steel bars clamped by the two positioning plates, thus completing the bending of the steel bars.

[0021] When the device needs to remove rust from the reinforcing bars, the uprights and curved plates are removed from the base plate. The second working mechanism drives the two positioning plates to move closer to each other, clamping the rusted reinforcing bars. Before this, a grinding disc is installed on the two positioning plates. The grinding disc can be fixed with bolts and is not shown in the diagram. The second working mechanism drives the two positioning plates and the grinding disc to rotate and grind the rusted reinforcing bars. At this time, the rusted reinforcing bars can be transported with the help of external conveying equipment to facilitate grinding and rust removal. Attached Figure Description

[0031] To more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0032] Example: Figures 1-8 As shown, the present invention provides an intelligent rebar tying device, including a base plate 1, a bracket 2 installed on the upper surface of the base plate 1, two working rods 3 arranged above the base plate 1, each working rod 3 having a working hole 31 at its lower end, and a first working mechanism for driving the two working rods 3 arranged on the bracket 2.

[0033] The working hole 31 is for steel wire to pass through and is used to tie the reinforcing bars. The steel wire is conveyed through the working hole 31 by an external conveying device.

[0034] Several uprights 61 are inserted into the upper surface of the base plate 1, and an arc-shaped plate 62 is fixed to the upper end of every two uprights 61.

[0035] The uprights 61 and the curved plate 62 are set to support the steel bars to be packaged, and the uprights 61 can be directly removed from the base plate 1 to facilitate other working states of the device body.

[0036] The first working mechanism drives the two working rods 3 to move downwards, causing the working hole 31 to move below the steel bar to be packed, allowing the steel wire to pass through the working hole 31. Figure 1 As shown in the diagram, the two working rods 3 are then driven to move upwards, so that the steel wire forms a semi-encirclement around the steel bar to be bundled. Next, the two working rods 3 are driven to swing towards each other, forming a closed loop with the steel wire. Finally, the two working rods 3 are driven to rotate, twisting the two ends of the steel wire together, thus completing the binding of the steel bar.

[0037] Two positioning plates 5 are provided above the base plate 1, as well as a second working mechanism for driving the two positioning plates 5.

[0038] When the device is binding the reinforcing bars, the second working mechanism can drive the two positioning plates 5 to move back and forth at both ends of the reinforcing bars, so that the ends of the reinforcing bars to be bound are in a relatively neat state.

[0039] When the device needs to complete the bending of the steel bar, the upright 61 and the arc plate 62 are removed from the base plate 1. The second working mechanism drives the two positioning plates 5 to move closer to each other, clamping the steel bar to be bent. Meanwhile, the first working mechanism drives one of the working rods 3 to a horizontal state and the other working rod 3 to a vertical state. The vertical working rod 3 can bend the steel bar clamped by the two positioning plates 5 by rotating, thereby completing the bending of the steel bar.

[0040] When the device needs to remove rust from the reinforcing bars, the upright 61 and the arc plate 62 are removed from the base plate 1. The second working mechanism drives the two positioning plates 5 to move closer to each other, clamping the rusted reinforcing bars. Before this, a grinding disc is installed on the two positioning plates 5. The grinding disc can be fixed with bolts. The grinding disc is not shown in the figure. The second working mechanism drives the two positioning plates 5 and the grinding disc to rotate and grind the rusted reinforcing bars. At this time, the rusted reinforcing bars can be transported with the help of external conveying equipment to facilitate grinding and rust removal.

[0041] The first working mechanism includes an annular sleeve 41 integrally formed with the bracket 2. An annular shaft 42 is rotatably connected inside the annular sleeve 41. An outer shell 43 is provided inside the annular shaft 42. At least two strip grooves 44 are opened on the surface of the outer shell 43. A block that matches the strip grooves 44 is integrally formed on the inner wall of the annular shaft 42.

[0042] The outer shell 43 and the annular shaft 42 can rotate within the annular sleeve 41, while the outer shell 43 can move in the vertical direction without affecting the annular shaft 42.

[0043] Two symmetrically distributed mounting slots 45 are provided on the side wall of the outer shell 43. The two working rods 3 are rotatably connected in the two mounting slots 45 respectively, and each mounting slot 45 is provided with a third complete gear 46 coaxially fixed with the working rod 3. The lower ends of the two working rods 3 are located on the same horizontal line. The lengths of the two working rods 3 are different, and the horizontal positions of the two third complete gears 46 are different.

[0044] An annular rack 47 is provided inside the outer shell 43, meshing with one of the higher-level third complete gears 46. A middle shell 48 extending to the outside of the outer shell 43 is fixedly connected to the upper surface of the annular rack 47. An annular rack 49 is provided inside the outer shell 43, meshing with another lower-level third complete gear 46. An inner shaft 410 passing through the middle shell 48 and extending to the outside of the middle shell 48 is fixed to the upper surface of the annular rack 49. Annular slide rails 411 are fixed at the upper edges of the outer shell 43, the middle shell 48, and the inner shaft 410. The outer shell 43 and the middle shell 48 are mutually mating splined shafts, and the middle shell 48 and the inner shaft 410 are mutually mating splined shafts.

[0045] The spline shaft structure allows the inner shaft 410, the middle housing 48, and the outer housing 43 to rotate simultaneously and move up and down individually.

[0046] Among them, the up-and-down movement of the ring rack 47 and the middle shell 48 can control the rotation of a corresponding working rod 3 through the third complete gear 46, and the up-and-down movement of the inner shaft 410 and the ring rack 49 can control the rotation of another corresponding working rod 3.

[0047] A cylindrical rod 412 is vertically fixed on the bracket 2. A horizontal plate 413 is fixedly connected to the top of the cylindrical rod 412. A limiting post 414 driven by an external motor is rotatably connected to the horizontal plate 413. An L-rod 415 is fixedly connected to the bracket 2. A rectangular sliding frame 416 is fixedly connected to the free end of the L-rod 415. Three rectangular blocks 417 are slidably connected inside the rectangular sliding frame 416. A sliding rod 418 passes through each of the three rectangular blocks 417. One end of each of the three sliding rods 418 is slidably adapted to three annular slide rails 411.

[0048] Among them, the uppermost slide bar 418 corresponds to the inner shaft 410, the middle slide bar 418 corresponds to the middle shell 48, and the lowermost slide bar 418 corresponds to the outer shell 43. The height of the outer shell 43, the middle shell 48, and the inner shaft 410 is controlled by the corresponding slide bar 418.

[0049] The surface of the limiting post 414 has three V-shaped grooves 419 arranged from top to bottom, and three horizontal grooves 420 arranged from top to bottom. The two ends of each horizontal groove 420 are connected to the two ends of the corresponding V-shaped groove 419. The three sliding rods 418 are respectively adapted to slide with the three V-shaped grooves 419 and the three horizontal grooves 420.

[0050] Each V-groove 419 is formed by two inclined grooves, and the two inclined grooves are symmetrically distributed. The length of the two inclined grooves on the lowermost V-groove 419 is slightly shorter than that of the two inclined grooves on the upper V-groove 419.

[0051] The surface of the limiting post 414 is provided with an inclined groove 421 and a horizontal groove 422 that communicates with the cylindrical rod 412. The inclined groove 421 communicates with the V-shaped groove 419 at the highest position. An electric baffle 424 is rotatably connected at the connection between the inclined groove 421 and the V-shaped groove 419. The sliding rod 418 is slidably adapted to the inclined groove 421 and the horizontal groove 422.

[0052] The surface of the limiting post 414 is provided with a horizontal groove 423. The horizontal groove 423 is connected to the V-shaped groove 419 in the middle position. An electric baffle 425 is rotatably connected at the connection between the horizontal groove 423 and the V-shaped groove 419. The slide rod 418 is slidably adapted to the horizontal groove 423.

[0053] A partial gear 426 is sleeved on the surface of the limiting post 414, and a rectangular block 417 that intermittently meshes with the partial gear 426 is fixedly connected to the upper end of the inner shaft 410.

[0054] The second working mechanism includes two bearing plates 71 that are vertically fixed to the upper surface of the base plate 1 and symmetrically distributed. A shaft 73 and a threaded rod 72, which are distributed vertically, are rotatably connected between the two bearing plates 71. There are two threaded rods 72, which are coaxially fixed and have opposite thread directions. Both the shaft 73 and the threaded rod 72 are driven by an external motor. An internal threaded sleeve 74 is fitted on the threaded rod 72 and threadedly connected to it. A long plate 75 is vertically fixed on the upper surface of the internal threaded sleeve 74. A through hole is opened on the surface of the long plate 75 for the shaft 73 to pass through. An outer bushing 76 is rotatably connected to the surface of the long plate 75 and fitted on the shaft 73. The outer bushing 76 and the shaft 73 are mutually compatible spline shafts. A first complete gear 77 is fitted on the outer bushing 76. Two positioning plates 5 are rotatably connected to the two long plates 75 respectively. A second complete gear 78 is provided on the long plate 75 and coaxially fixed with the positioning plate 5. The second complete gear 78 and the first complete gear 77 mesh with each other.

[0055] Working principle:

[0056] When it is necessary to tie the reinforcing bars, the produced reinforcing bars are first placed on the arc plate 62. The threaded rod 72 is driven by the motor to rotate back and forth. The threaded rod 72 can drive the positioning plate 5 to move back and forth in the horizontal direction through the inner threaded sleeve 74 and the long plate 75, so that the two positioning plates 5 push off the two ends of the reinforcing bars and make the ends of the reinforcing bars neat.

[0057] In the initial state, electric baffle 1 424 is blocked at the port of inclined groove 421, and electric baffle 2 425 is blocked at the port of horizontal groove 3 423, causing inclined groove 421, horizontal groove 2 422 and horizontal groove 3 423 to be temporarily unusable.

[0058] In the initial state, two of the sliding rods 418 are located at the electric baffle 1 424 and the electric baffle 2 425 respectively, and the other sliding rod 418 is located at the connection between the bottom V-shaped groove 419 and the horizontal groove 1 420. At this time, the two working rods 3 are located above the steel bars to be tied.

[0059] Driven by an external motor, the limiting post 414 rotates clockwise, and the three sliding rods 418 move downward along the corresponding V-groove 419. This causes the inner shaft 410, the middle shell 48, and the outer shell 43 to move downward through the three annular slide rails 411. At the same time, the two working rods 3 also move downward, allowing the working holes 31 on the working rods 3 to move below the reinforcing bars to be tied, and the steel wire to be threaded into the two working holes 31.

[0060] Then the limiting post 414 continues to rotate clockwise, and the three sliding rods 418 will move upward along the corresponding V-groove 419, so that the two working rods 3 will also move upward. At this time, the steel wire will partially surround the steel bar.

[0061] As the limiting post 414 rotates clockwise, the lowest sliding rod 418 will enter the horizontal groove 420 ahead of time. Because the inclined groove of the lowest V-groove 419 is slightly shorter than the inclined groove of the two upper V-grooves 419, the outer shell 43 stops moving upward first, while the inner shaft 410 and the middle shell 48 continue to move upward. As a result, the first ring rack 47 and the second ring rack 49 also continue to move upward. Since the two third complete gears 46 have stopped moving upward with the outer shell 43, the two third complete gears 46 will rotate due to the upward movement of the first ring rack 47 and the second ring rack 49. The two third complete gears 46 will drive the working rod 3, which is fixed to the same axis, to rotate, so that the two working rods 3 clamp the ends of the steel wire together.

[0062] At this time, all three sliding rods 418 have entered the horizontal groove 420, and the non-complete gear 426 is meshed with the complete gear 427, causing the complete gear 427 to rotate. The complete gear 427 can drive the inner shaft 410, the middle shell 48 and the outer shell 43 to rotate. The outer shell 43 can drive the two working rods 3 to rotate, thereby twisting the ends of the steel wire together and completing the packaging work.

[0063] When the three slide rods 418 move from the other end of the three horizontal grooves 420 to the V-groove 419 to return to their initial positions, the two upper slide rods 418 will enter the corresponding V-groove 419 in advance. This is because the inclined groove of the lowermost V-groove 419 is slightly shorter than the inclined groove of the two upper V-groove 419, which causes the inner shaft 410 and the middle shell 48 to move downward first. The first ring rack 47 and the second ring rack 49 also move downward first. The first ring rack 47 and the second ring rack 49 drive the two third complete gears 46 to rotate, so that the two working rods 3 also return to their initial vertical state.

[0064] When it is necessary to bend the steel bars, remove the upright 61 and the arc plate 62 from the base plate 1, drive the two positioning plates 5 to move closer to each other, and clamp the steel bars to be bent.

[0065] Rotate the electric baffle 424 into the corresponding V-groove 419, and rotate the electric baffle 425 into the corresponding V-groove 419, so that the inclined groove 421, the horizontal groove 422 and the horizontal groove 423 are in the open state.

[0066] Two of the slide bars 418 are located at electric baffle 1 424 and electric baffle 2 425 respectively, and the other slide bar 418 is located at the connection between the bottom V-shaped groove 419 and the horizontal groove 1 420.

[0067] At this time, the drive limit post 414 rotates counterclockwise. The lowermost slide rod 418 will directly enter the corresponding horizontal groove 420, the middle slide rod 418 will enter the horizontal groove 423, and the uppermost slide rod 418 will move down along the inclined groove 421 to the horizontal groove 422, thereby driving the inner shaft 410 and the ring rack 49 to move down. The ring rack 49 can drive the corresponding third complete gear 46 to rotate. The third complete gear 46 can drive the corresponding working rod 3 to rotate to a horizontal state, while the other working rod 3 remains in a vertical state.

[0068] Then, the incomplete gear 426 meshes with the complete gear 427, causing the complete gear 427 to rotate. The complete gear 427 can drive the inner shaft 410, the middle shell 48 and the outer shell 43 to rotate accordingly. The horizontal working rod 3 and the vertical working rod 3 also rotate accordingly. The vertical working rod 3 can push the steel bar held by the two positioning plates 5 to perform bending work.

[0069] When it is necessary to remove rust from the reinforcing bars, remove the uprights 61 and the arc plate 62 from the base plate 1, drive the two positioning plates 5 to move closer to each other, and clamp the rusted reinforcing bars. Before this, a grinding disc should be installed on the two positioning plates 5. The grinding disc can be fixed with bolts. The grinding disc is not shown in the figure.

[0070] Next, the shaft 73 is driven to rotate by an external motor. The shaft 73 can drive the outer bushing 76 to rotate, and the outer bushing 76 can drive the first complete gear 77 sleeved on its surface to rotate. The first complete gear 77 can drive the second complete gear 78 meshing with it to rotate, and the second complete gear 78 can drive the positioning plate 5 fixed coaxially with it to rotate. The positioning plate 5 can drive the grinding disc mounted on its surface to rotate, so that the two grinding discs can rotate and grind while clamping the steel bar to remove rust from the steel bar. At this time, the rusted steel bar can be transported with the help of external conveying equipment to facilitate grinding and rust removal.
