Description

Technical Field

[0001] This invention relates to the field of packaging machinery technology, specifically to an automatic bundling machine for bundling steel coils and its usage method. Background Technology

[0002] Steel coils include strip steel coils, rebar steel coils, and other types. After the steel coils are produced, they need to be rolled up and then bundled evenly along the circumference using steel strips to fix them in place for easy transportation and use. Manually bundling with steel strips is time-consuming and labor-intensive, so bundling machines are often used for automatic bundling.

[0003] Patent CN104003014B discloses a steel clamping, forming and bundling integrated machine, which clamps steel with left and right clamping arms and then transports the steel to a designated location for bundling to ensure that the steel is clamped and formed and will not be scattered.

[0004] However, the above invention is not applicable to the bundling of steel coils. For annular steel coils, they often need to be hoisted and placed into the guide groove of the bundling machine during bundling, making horizontal feeding impossible. This makes the loading and unloading process more troublesome and makes it difficult to bundle them evenly.

[0005] Based on this, the present invention designs an automatic bundling machine for bundling steel coils and its usage method to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automatic bundling machine for bundling steel coils and a method for using it.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An automatic baling machine for bundling steel coils includes a support frame;

[0009] A bundling assembly is installed on the upper side wall of the support, and a turntable assembly for rotating materials and multiple lifting assemblies for lifting materials are installed in front of the support.

[0010] The turntable assembly includes a rotary clamping assembly and a cover plate assembly; the rotary clamping assembly is installed at the front of the bracket, and the support arm end of the rotary clamping assembly is connected to the cover plate assembly.

[0011] Furthermore, the rotary clamping assembly includes a rotary base, support arms, sliding grooves, tension springs, baffles, sliding blocks, and baffle cylinders; a motor is installed inside the rotary base, and the output end of the rotary base is fixedly connected to the inner ends of multiple sets of support arms; each support arm has a sliding groove at its top outer end, the inner wall of the sliding groove is slidably connected to the side wall of the sliding block, and the top of the sliding block is fixedly connected to the bottom of the baffle; the inner and outer ends of the tension spring are fixedly connected to the inner wall of the sliding groove and the inner side wall of the sliding block, respectively; each support arm has a baffle cylinder fixedly connected to its bottom inner end, and the output end of the baffle cylinder faces the outer end of the support arm; each support arm is connected to a cover plate assembly.

[0012] Furthermore, the bottom of the baffle is connected to the top of the support arm.

[0013] Furthermore, the cover plate assembly includes a cover plate, a rotating shaft, and a torsion spring; each of the support arms has a shaft hole that is rotatably connected to the side wall of the rotating shaft, and both ends of the rotating shaft are fixedly connected to the lower end of the side wall of the cover plate; the inner and outer ends of the torsion spring are fixedly connected to the side wall of the rotating shaft and the side wall of the support arm, respectively.

[0014] Furthermore, the lifting assembly includes a base plate, lifting cylinders, support rods, and rotating rollers; multiple sets of base plates are installed in front of the bracket, and the base plates are arranged around the rotating base; multiple sets of lifting cylinders are symmetrically fixedly connected to both sides of the top of the base plate; the two ends of the rotating rollers are rotatably connected to the side walls of two sets of support rods respectively, and the bottoms of the two sets of support rods are fixedly connected to the output end of the lifting cylinder on the same side respectively.

[0015] Furthermore, the base plate consists of three sets, which are evenly distributed along the circumference.

[0016] Furthermore, the lifting cylinders consist of four groups arranged in a rectangular array.

[0017] To better achieve the objectives of this invention, this invention also provides a method for using an automatic bundling machine for bundling steel coils, comprising the following steps:

[0018] Step 1: The external boom moves the material horizontally onto the rotating roller. At this time, the lifting cylinder is in the extended state, and the bottom of the material is separated from the top of the support arm. Then the lifting cylinder retracts, driving the support rod to descend, which in turn drives the rotating roller and the material to descend. The bottom of the material contacts the support arm, thus placing the material on the support arm. At the same time, the rotating roller descends to below the support arm, and the material is now located between the guide groove ends of the bundling assembly.

[0019] Step 2: The baffle cylinder retracts, the tension spring retracts, and the sliding block slides inward along the slide groove, thereby causing the baffle to slide and clamp the material inward; the baffle cylinder continues to retract, the torsion spring drives the rotating shaft to rotate, causing the cover plate to flip outward, thereby pressing the material.

[0020] Step 3: The guide groove end of the bundling assembly closes, forming a closed loop; the external feeding mechanism feeds material, allowing the steel strip to pass through the guide groove end of the bundling assembly and form a closed loop; then the movable end of the bundling assembly moves down, causing the snap-lock end of the bundling assembly to stick to the material; then the external feeding mechanism rewinds the steel strip, tightens the steel strip, and the snap-lock machine snaps it in place.

[0021] Step 4: After bundling is completed, the movable end of the bundling component is lifted and reset, and the guide groove end of the bundling component opens; the rotating base rotates, driving the support arm to rotate, thereby driving the material to rotate, and continuing to bundle other positions;

[0022] Step 5: After all the current material is bundled around the circumference, the baffle cylinder extends, pushes the bottom of the cover plate and flips it inward, and pushes the baffle to move outward to loosen the material. The lifting cylinder extends, driving the support rod and the rotating roller to lift the material. At this time, the external crane arm will transport and unload the material horizontally.

[0023] The present invention has the following technical effects:

[0024] 1. The present invention allows materials to be directly fed horizontally for bundling by opening and closing the guide groove end of the bundling component, and facilitates the rotation of the turntable component, resulting in higher working efficiency and more effective processing of annular material rolls.

[0025] 2. This invention uses a baffle cylinder to extend and retract, which can fix materials from both the inside and outside sides, preventing the materials from scattering and facilitating bundling;

[0026] 3. By adjusting the height of the rotating rollers, the present invention supports the horizontal movement of materials, allowing the crane boom to move horizontally for transportation without the need to adjust the vertical movement of the boom, thus enabling faster loading and unloading.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] The present invention will be further described below with reference to embodiments.

[0041] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to... Figure 2 The direction of the viewpoint.

[0042] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-9 An automatic baling machine for bundling steel coils includes a support frame 1;

[0043] The upper side wall of the support 1 is equipped with a bundling assembly 2, and a turntable assembly 3 for rotating materials and multiple sets of lifting assemblies 4 for lifting materials are installed in front of the support 1.

[0044] The bundling assembly 2 includes a snap fastener assembly 21 and a guide rail assembly 22. The snap fastener assembly 21 is installed on the upper side wall of the bracket 1 and is connected to the guide rail assembly 22.

[0045] The snap fastener assembly 21 includes a linear module 211, a linear guide rail assembly 212, a cantilever 213, and a first support frame 214; the linear module 211 and the linear guide rail assembly 212 are fixedly connected to the upper side wall of the support 1; the output end of the linear module 211 and the slider end of the linear guide rail assembly 212 are both fixedly connected to the rear side wall of the cantilever 213; the first support frame 214 is fixedly connected to the side wall of the cantilever 213, and the bottom snap fastener 215 of the first support frame 214 is fixedly connected to the top; the side wall of the cantilever 213 is connected to the guide rail assembly 22.

[0046] The guide rail assembly 22 includes a second support frame 221, a fixed guide groove 222, a third support frame 223, a movable guide groove 224, and a tilting cylinder 225. The second support frame 221 and the third support frame 223 are fixedly connected to the side wall of the cantilever 213. The bottom of the second support frame 221 is fixedly connected to the top of the fixed guide groove 222, and the bottom of the third support frame 223 is rotatably connected to the top of the movable guide groove 224 through a hinge seat. The fixed end and the output end of the tilting cylinder 225 are rotatably connected to the upper end of the front side wall of the third support frame 223 and the top of the movable guide groove 224 respectively through a hinge seat.

[0047] In operation, the external boom transports the material to the lifting assembly 4. The supporting end of the lifting assembly 4 then lowers, placing the material onto the turntable assembly 3. The turntable assembly 3 secures the material, which is then positioned between the fixed guide groove 222 and the movable guide groove 224 of the guide rail assembly 22 of the bundling assembly 2. Subsequently, the tilting cylinder 225 extends, causing the movable guide groove 224 to tilt downwards until its lower end contacts the front end of the fixed guide groove 222, forming a closed loop. An external feeding mechanism feeds the material, allowing the steel strip to pass through the feed inlet of the snapping machine 215 of the snapping assembly 21, then extend and circle once along the fixed guide groove 222 and the movable guide groove 224, returning to the feed inlet of the snapping machine 215 to form a closed loop. Finally, the linear module 211 starts, driving the cantilever 213 along the linear guide rail assembly... 212 moves down, causing the snap-on machine 215 to move down as well, so that the bottom of the snap-on machine 215 is in contact with the material. Then, the external feeding mechanism rewinds the steel strip, tightens the steel strip, and the snap-on machine performs the snap-on action. After the binding is completed, the linear module 211 drives the linear guide rail assembly 212 to lift and reset, while the flipping cylinder 225 retracts, causing the movable guide groove 224 to flip upward. At this time, the turntable assembly 3 rotates, causing the material to rotate to the next binding position for binding. After the current material is completely bound around the circumference, the turntable assembly 3 is released from its fixed position, and the material is lifted by the lifting assembly 4. Then, the external cantilever unloads the material. By flipping the cylinder 225 to drive the movable guide groove 224 to flip, the material can be directly fed horizontally for binding, and the turntable assembly 3 can be rotated more easily, resulting in higher working efficiency and more effective handling of annular material rolls.

[0048] The turntable assembly 3 includes a rotary clamping assembly 31 and a cover plate assembly 32; the rotary clamping assembly 31 is installed in front of the bracket 1, and the support arm end of the rotary clamping assembly 31 is connected to the cover plate assembly 32.

[0049] The rotary clamping assembly 31 includes a rotary base 311, support arms 312, slide grooves 313, tension springs 314, baffles 315, sliding blocks 316, and baffle cylinders 317. A motor is installed inside the rotary base 311, and the output end of the rotary base 311 is fixedly connected to the inner ends of multiple sets of support arms 312. Each support arm 312 has a slide groove 313 at its top outer end, and the inner wall of the slide groove 313 is slidably connected to the side wall of the sliding block 316. The top of the sliding block 316 is fixedly connected to the bottom of the baffle 315. The inner and outer ends of the tension spring 314 are fixedly connected to the inner wall of the slide groove 313 and the inner side wall of the sliding block 316, respectively. Each support arm 312 has a baffle cylinder 317 fixedly connected to its bottom inner end, with the output end of the baffle cylinder 317 facing the outer end of the support arm 312. Each support arm 312 is connected to a cover plate assembly 32.

[0050] Preferably, the bottom of the baffle 315 is in contact with the top of the support arm 312.

[0051] During operation, the external boom transports the material to the lifting assembly 4. Then, the supporting end of the lifting assembly 4 descends, placing the material onto the supporting arm 312 of the rotating clamping assembly 31 of the turntable assembly 3. At this time, the baffle cylinder 317 is in the extended state, and the sliding block 316 is pushed to the outer end of the slide groove 313 by the output end of the baffle cylinder 317. The tension spring 314 is in the stretched state, and the cover plate assembly 32 tilts inward. After the material is placed, the baffle cylinder 317 retracts, the tension spring 314 retracts, causing the sliding block 316 to slide inward along the slide groove 313, thereby driving the baffle... The plate 315 slides, clamping the material inward; the baffle cylinder 317 continues to retract, and the cover assembly 32 flips outward, thus pressing down on the material; the rotating base 311 rotates, driving the support arm 312 to rotate, thereby causing the material to rotate for binding; after the current material is completely bound around the circumference, the baffle cylinder 317 extends again, pushing the cover assembly 32 and causing it to flip inward, and pushing the baffle 315 to move outward, releasing the material; through the extension and retraction of the baffle cylinder 317, the material can be squeezed and fixed to prevent it from scattering, making binding easier.

[0052] In some embodiments, such as Figure 1-9 As shown, in a preferred embodiment of the present invention, the cover plate assembly 32 includes a cover plate 321, a rotating shaft 322, and a torsion spring 323; each of the support arms 312 has a shaft hole that is rotatably connected to the side wall of the rotating shaft 322, and both the left and right ends of the rotating shaft 322 are fixedly connected to the lower end of the side wall of the cover plate 321; the inner and outer ends of the torsion spring 323 are fixedly connected to the side wall of the rotating shaft 322 and the side wall of the support arm 312, respectively.

[0053] During operation, the external boom transports the material to the lifting assembly 4. Then, the supporting end of the lifting assembly 4 descends, placing the material onto the supporting arm 312 of the rotating clamping assembly 31 of the turntable assembly 3. At this time, the baffle cylinder 317 is in the extended state, and the sliding block 316 is pushed to the outer end of the slide groove 313 by the output end of the baffle cylinder 317. The tension spring 314 is in the stretched state, and the cover plate 321 of the cover plate assembly 32 is blocked by the output end of the baffle cylinder 317, causing it to tilt inwards. After the material is placed, the baffle cylinder 317 retracts, the tension spring 314 retracts, causing the sliding block 316 to slide inwards along the slide groove 313, thereby driving the baffle 31... 5. Sliding clamps the material inward; the baffle cylinder 317 continues to retract, the torsion spring 323 drives the rotating shaft 322 to rotate, causing the cover plate 321 to flip outward, thus pressing the material; the rotating base 311 rotates, causing the support arm 312 to rotate, thus causing the material to rotate for binding; after the current material is completely bound around the circumference, the baffle cylinder 317 extends again, pushing the bottom of the cover plate 321 and causing it to flip inward, and pushing the baffle 315 to move outward, releasing the material; through the extension and retraction of the baffle cylinder 317, the baffle 315 and the cover plate 321 can fix the material from both inside and outside, preventing the material from scattering.

[0054] In some embodiments, such as Figure 1-9 As shown, in a preferred embodiment of the present invention, the lifting assembly 4 includes a base plate 41, a lifting cylinder 42, a support rod 43, and a rotating roller 44; multiple sets of base plates 41 are installed in front of the bracket 1, and the base plates 41 are arranged around the rotating base 311; multiple sets of lifting cylinders 42 are symmetrically fixedly connected to both sides of the top of the base plate 41; the two ends of the rotating roller 44 are respectively rotatably connected to the side walls of two sets of support rods 43, and the bottoms of the two sets of support rods 43 are respectively fixedly connected to the output end of the lifting cylinder 42 on the same side.

[0055] Preferably, the base plate 41 consists of three groups and is evenly distributed along the circumference.

[0056] Preferably, there are four sets of lifting cylinders 42 arranged in a rectangular array.

[0057] In operation, the external boom moves the material horizontally onto the rotating roller 44. At this time, the lifting cylinder 42 is in the extended state, and the bottom of the material is separated from the top of the support arm 312. Subsequently, the lifting cylinder 42 retracts, driving the support rod 43 to descend, thereby driving the rotating roller 44 and the material to descend. The bottom of the material contacts the support arm 312, thus placing the material on the support arm 312. At the same time, the rotating roller 44 descends below the support arm 312, without obstructing the rotation of the support arm 312. After the current material is completely bundled around the circumference, the lifting cylinder 42 extends, driving the support rod 43 and the rotating roller 44 to lift the material. At this time, the external boom transports and unloads the material horizontally. By adjusting the height of the rotating roller 44 to support the horizontal movement of the material, the boom only needs to move horizontally for transportation, without needing to adjust the boom's vertical movement, allowing for faster loading and unloading.

[0058] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-9 A method of using an automatic bundling machine for bundling steel coils includes the following steps:

[0059] Step 1: The external boom moves the material horizontally onto the rotating roller 44. At this time, the lifting cylinder 42 is in the extended state, and the bottom of the material is separated from the top of the support arm 312. Then the lifting cylinder 42 retracts, driving the support rod 43 to descend, thereby driving the rotating roller 44 and the material to descend. The bottom of the material contacts the support arm 312, thus placing the material on the support arm 312. At the same time, the rotating roller 44 descends to below the support arm 312. At this time, the material is located between the fixed guide groove 222 and the movable guide groove 224 of the guide rail assembly 22 of the bundling assembly 2.

[0060] Step 2: The baffle cylinder 317 retracts, the tension spring 314 retracts, driving the sliding block 316 to slide inward along the slide groove 313, thereby driving the baffle 315 to slide and clamp the material inward; the baffle cylinder 317 continues to retract, the torsion spring 323 drives the rotating shaft 322 to rotate, driving the cover plate 321 to flip outward, thereby pressing the material.

[0061] Step 3: The tilting cylinder 225 extends, causing the movable guide groove 224 to tilt downwards until the lower end of the movable guide groove 224 contacts the front end of the fixed guide groove 222, forming a closed ring. The external feeding mechanism feeds the steel strip through the feed inlet of the snapping machine 215 of the snapping assembly 21, then extends and circles around the fixed guide groove 222 and the movable guide groove 224, returning to the feed inlet of the snapping machine 215 to form a closed ring. Subsequently, the linear module 211 starts, driving the cantilever 213 to move down along the linear guide assembly 212, driving the snapping machine 215 down, so that the bottom of the snapping machine 215 is in contact with the material. Then, the external feeding mechanism rewinds the steel strip, tightens the steel strip, and the snapping machine performs snapping.

[0062] Step 4: After the binding is completed, the linear module 211 drives the linear guide rail assembly 212 to lift and reset, while the flipping cylinder 225 retracts, causing the movable guide groove 224 to flip upward; the rotating base 311 rotates, driving the support arm 312 to rotate, thereby driving the material to rotate, and continuing to bind other positions;

[0063] Step 5: After all the current material is bundled around the circumference, the baffle cylinder 317 extends, pushes the bottom of the cover plate 321 and flips it inward, and pushes the baffle 315 to move outward to loosen the material. The lifting cylinder 42 extends, driving the support rod 43 and the rotating roller 44 to lift the material. At this time, the external crane arm will transport and unload the material horizontally.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
