Description

Technical Field

[0001] This invention belongs to the field of steel wire coil processing technology, and in particular relates to a steel wire coil turning and feeding device. Background Technology

[0002] Wire coils, especially steel wire coils, are prone to oxidation and rust when left outdoors for extended periods. Before using the steel wire to process related metal products, its surface needs to be treated to remove rust and scale. Steel wire arrives in coils, commonly referred to as steel wire coils. During rust removal, the steel wire is guided into the rust removal machine by a rotating feed rack. Therefore, before rust removal, the steel wire coil needs to be placed on the feed rack.

[0003] In existing technologies, the most common method for loading wire coils onto a feeding rack involves using an overhead crane to horizontally lift the wire coil, then manually lifting the feeding rack to load the wire coil from its horizontal position, and finally flipping the feeding rack with the wire coil onto its vertical position. While this method meets the requirements, it is inefficient, labor-intensive, and poses safety hazards due to the risk of injury to workers during the lifting process. Therefore, there is an urgent need to research a wire coil flipping and feeding device to solve these problems. Summary of the Invention

[0004] The present invention provides a wire coil turning and feeding device, the purpose of which is to solve the technical problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] The present invention is a wire coil turning and feeding device, comprising a support frame; a turning drive mechanism is mounted on the support frame; a base plate is connected to the turning drive mechanism; a feeding rack is placed on one surface of the base plate; a positioning mechanism and a supporting mechanism corresponding to the feeding rack are mounted on the base plate; the positioning mechanism and the supporting mechanism are connected by a linkage mechanism; the linkage mechanism is mounted on the base plate.

[0007] In a preferred embodiment of the present invention, the support frame includes a pair of side support beams arranged side by side; the two side support beams are connected by a pair of H-shaped frames arranged side by side; the H-shaped frames are disposed below the side support beams; a limiting plate is horizontally disposed between the two H-shaped frames; one opposite edge of the limiting plate is fixed to the opposite side surface of the two side support beams. When the substrate is in a horizontal state, the lower surface of the substrate is in contact with the upper surface of the limiting plate, thereby achieving positioning of the substrate; when the substrate is in a vertical state, the supporting mechanism is placed on the middle section of one of the H-shaped frames, thereby achieving repositioning of the substrate and ensuring the flipping effect of the substrate.

[0008] As a preferred embodiment of the present invention, the flipping drive mechanism includes a pair of drive shafts rotatably inserted into the opposite sides of the two side support beams, and a transmission shaft with both ends rotatably connected to the opposite sides of the two side support beams; each of the two drive shafts has a movable plate rotatably connected to one of its proximal ends; the two movable plates are respectively fixed to opposite sides of the base plate; a first gear is provided between the movable plate and the adjacent side support beam; the first gear is fixedly sleeved on the outer periphery of the drive shaft; an internal gear ring is coaxially provided on the outer periphery of the first gear; the internal gear ring is fixed to the adjacent side support beam by a plurality of mounting posts. On the side support beam; a pair of second gears are symmetrically arranged between the internal gear ring and the first gear; one end of the axle of each of the two second gears is rotatably connected to the two ends of an adjacent movable strip; the second gears mesh with both the internal gear ring and the first gear; a reducer is connected to the transmission shaft; the reducer is fixed to one side of the limiting plate; a first servo motor is connected to the reducer; first pulleys are fixedly sleeved at both ends of the transmission shaft; the two first pulleys are respectively connected to second pulleys via belt drive; the two second pulleys are respectively fixedly sleeved on the ends of the two drive shafts that are separated. The first servo motor drives the two drive shafts to rotate synchronously via the reducer, transmission shaft, first pulleys, and second pulleys, causing the two first gears to drive the two pairs of second gears to roll on the two internal gear rings, thereby realizing the rotation of the substrate around the drive shaft. This not only ensures stable and labor-saving rotation but also effectively guarantees the rotation effect of the substrate.

[0009] In a preferred embodiment of the present invention, the feeding rack includes an outer ring and an inner ring coaxially arranged; the outer ring and the inner ring are connected by a plurality of first connecting posts; a plurality of support rods are evenly distributed and fixed on the inner ring along the axial direction; the plurality of support rods are connected by a plurality of second connecting posts; the ends of the plurality of support rods away from the inner ring are connected by a connecting plate; a lifting ring is fixed to the end face of the connecting plate away from the inner ring. By placing the outer ring and the inner ring on the substrate and locking the inner ring using a positioning mechanism, the entire feeding rack is stably installed on the substrate; when the feeding rack is unlocked, it is removed from the substrate by the lifting ring.

[0010] As a preferred embodiment of the present invention, a plurality of first sliding grooves corresponding to the positioning mechanism are evenly distributed on one surface of the substrate; the positioning mechanism includes a plurality of cylindrical cams arranged in a circumferential direction; the length direction of the cylindrical cams is parallel to the length direction of the corresponding first sliding grooves; the cylindrical cams are located on the side of the first sliding groove away from the feeding rack; both ends of the axle of the cylindrical cams are rotatably connected to first support blocks; the first support blocks are fixed to the substrate; a movable column is slidably inserted into the working groove of the cylindrical cams; the end of the movable column away from the cylindrical cams is inserted into the first sliding groove and fixed with a positioning block; the positioning block is slidably inserted into the first sliding groove; a first guide rod parallel to the cylindrical cams is slidably inserted into the positioning block; the two ends of the first guide rods are respectively fixed to the opposite two sides of the first sliding groove; the end of the positioning block away from the movable column extends out of the first sliding groove, and this end has a receiving groove corresponding to the inner ring. By rotating the cylindrical cam, the movable column is driven to move, causing the positioning block to slide in the first groove and bringing the receiving groove close to the inner ring. When the movable column moves to one end of the cylindrical cam, the inner ring is in the receiving groove, thereby achieving the positioning of the feeding rack. This not only ensures accurate positioning of the feeding rack but also enables rapid positioning of the feeding rack.

[0011] As a preferred embodiment of the present invention, a pair of second sliding grooves corresponding to the supporting mechanism are symmetrically formed on one side of the substrate; the length directions of the two second sliding grooves are respectively parallel to the two diagonals of the substrate; the supporting mechanism includes a lead screw disposed between the two second sliding grooves; the lead screw is perpendicular to one side of the substrate; the lead screw is disposed on the side of the second sliding groove away from the feeding rack; both ends of the lead screw are rotatably connected to second support blocks; the second support blocks are fixed to the substrate; a nut is threaded onto the lead screw; a second guide rod perpendicular to the lead screw is fixedly inserted at one end of the nut; sliding sleeves are slidably fitted at both ends of the second guide rod; a bearing block is fixedly fitted on the outer periphery of each of the two sliding sleeves; the two bearing blocks are slidably inserted into the two second sliding grooves; a lifting plate corresponding to the feeding rack is fixed at the end of the bearing block away from the sliding sleeve. By rotating the lead screw in the forward direction, the lead screw nut drives the second guide rod closer to the feeding frame, thereby causing the bearing block to slide in the second slide groove and the lifting plate to approach the feeding frame. Similarly, rotating the lead screw in the reverse direction causes the lifting plate to move away from the feeding frame. This not only prevents the feeding frame from affecting the placement of the wire coil on the feeding frame, but also stably constrains the wire coil on the feeding frame during the flipping process of the feeding frame.

[0012] As a preferred embodiment of the present invention, the linkage mechanism includes a second servo motor whose output shaft is coaxially connected to one end of a lead screw, and a mounting shaft disposed between multiple cylindrical cams; the second servo motor is fixed on a base plate; the mounting shaft is perpendicular to the cylindrical cams; one end of the mounting shaft is rotatably connected to the base plate; a one-way bevel gear and a first bevel gear are sleeved side by side on the mounting shaft; multiple second bevel gears corresponding to the cylindrical cams mesh on the one-way bevel gears; the second bevel gears are fixedly sleeved on one end of the wheel axle of the cylindrical cams; a third bevel gear corresponding to the lead screw meshes on the first bevel gears; and the third bevel gears are fixedly sleeved on the other end of the lead screw. When the feeding rack is placed vertically on the substrate, the output shaft of the second servo motor rotates in the reverse direction. At this time, the lead screw rotates in the reverse direction, and the lifting plate gradually moves away from the feeding rack. Simultaneously, the lead screw, the third bevel gear, the first bevel gear, the mounting shaft, the one-way bevel gear, and the second bevel gear drive the cylindrical cam to rotate, causing the movable column to move to one end of the cylindrical cam, with the inner ring positioned in the receiving groove. This achieves the positioning mechanism locking the feeding rack on the substrate and maximizing the distance between the support mechanism and the feeding rack. When the wire coil is looped onto the horizontally set feeding rack, the output shaft of the second servo motor rotates in the forward direction, and the lead screw rotates in the forward direction to drive... When the lifting plate approaches the feeding rack, the one-way bevel gear does not rotate, and the positioning mechanism always keeps the feeding rack stably locked on the base plate. When the feeding rack carrying the wire coil flips from a flat position to a vertical position, the output shaft of the second servo motor rotates in the opposite direction. At this time, the lead screw rotates in the opposite direction, and the lifting plate gradually moves away from the feeding rack. At the same time, the lead screw, the third bevel gear, the first bevel gear, the mounting shaft, the one-way bevel gear, and the second bevel gear drive the cylindrical cam to rotate, causing the movable column to move to the other end of the cylindrical cam, and the inner ring moves away from the receiving groove. This achieves the positioning mechanism unlocking the feeding rack and the support mechanism moving away from the feeding rack.

[0013] The present invention has the following beneficial effects:

[0014] This invention first uses a flipping drive mechanism to rotate the substrate to a horizontal position, then places the feeding rack vertically on the substrate. Next, a linkage mechanism drives the positioning and supporting mechanisms to move, maximizing the distance between the positioning mechanism and the feeding rack, ensuring effective positioning of the feeding rack and preventing the supporting mechanism from interfering with the placement of the wire coil on the feeding rack. Then, the flipping drive mechanism rotates the substrate with the feeding rack by 90°, changing the feeding rack from a vertical to a horizontal position. Finally, a crane or forklift is used to place the wire coil onto the horizontally positioned feeding rack. The wire coil is placed on the rack, and the linkage mechanism drives the supporting mechanism to approach the feeding rack (the positioning mechanism remains stationary throughout this process). This causes the supporting mechanism to press against the wire coil on the feeding rack. Then, the flipping drive mechanism controls the base plate to flip the feeding rack from a flat position to an upright position. The linkage mechanism then drives the positioning mechanism and the supporting mechanism to move, causing the positioning mechanism to unlock the feeding rack and the supporting mechanism to move away from the feeding rack. The feeding rack with the wire coil can then be moved to the desired position. This not only effectively improves the efficiency of flipping and feeding the wire coil, but also reduces the labor intensity of workers and avoids some safety hazards.

[0015] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Implementation

[0032] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific Implementation

[0033] Please see Figure 1 As shown, the present invention is a wire coil turning and feeding device, including a support frame 1; a turning drive mechanism 2 is installed on the support frame 1; a base plate 3 is connected to the turning drive mechanism 2; a feeding rack 4 is placed on one surface of the base plate 3; a positioning mechanism 5 and a supporting mechanism 6 corresponding to the feeding rack 4 are installed on the base plate 3; the positioning mechanism 5 and the supporting mechanism 6 are connected by a linkage mechanism 7; the linkage mechanism 7 is installed on the base plate 3. In use, the substrate 3 is first rotated to a horizontal position by the flipping drive mechanism 2, and then the feeding rack 4 is placed vertically on the substrate 3. Then, the linkage mechanism 7 drives the positioning mechanism 5 and the supporting mechanism 6 to move, causing the positioning mechanism 5 to lock the feeding rack 4 on the substrate 3 and maximizing the distance between the supporting mechanism 6 and the feeding rack 4. This not only ensures the positioning effect of the feeding rack 4 but also prevents the supporting mechanism 6 from affecting the placement of the wire coil on the feeding rack 4. Then, the flipping drive mechanism 2 rotates the substrate 3 with the feeding rack 4 by 90°, causing the feeding rack 4 to change from a vertical to a horizontal position. Finally, a crane or forklift is used to place the wire coil onto the horizontally positioned feeding rack 4. On the feed rack 4, the linkage mechanism 7 drives the support mechanism 6 to approach the feed rack 4 (the positioning mechanism 5 remains stationary throughout this process), causing the support mechanism 6 to press tightly against the wire roll on the feed rack 4. Then, the flipping drive mechanism 2 controls the base plate 3 to flip the feed rack 4 from a flat position to an upright position. Then, the linkage mechanism 7 drives the positioning mechanism 5 and the support mechanism 6 to move, causing the positioning mechanism 5 to unlock the feed rack 4 and the support mechanism 6 to move away from the feed rack 4. Then, the feed rack 4 with the wire roll can be moved to the required position. This not only effectively improves the flipping and feeding efficiency of the wire roll, but also reduces the labor intensity of workers and avoids some safety hazards.

[0034] Among them, such as Figure 2As shown, the support frame 1 includes a pair of side support beams 101 arranged side by side; the two side support beams 101 are connected by a pair of H-shaped frames 102 arranged side by side; the two upper ends of the H-shaped frames 102 are respectively screwed to the side support beams 101; the H-shaped frames 102 are located below the side support beams 101; a limiting plate 103 is horizontally arranged between the two H-shaped frames 102; one opposite edge of the limiting plate 103 is respectively bolted to the opposite side of the side support beams 101. When the substrate 3 is in a horizontal state, the lower surface of the substrate 3 is in contact with the upper surface of the limiting plate 103, thereby achieving the positioning of the substrate 3; when the substrate 3 is in a vertical state, the supporting mechanism 6 is placed on the middle section of an H-shaped frame 102, thereby achieving the repositioning of the substrate 3 and ensuring the flipping effect of the substrate 3. Specific Implementation

[0035] Based on specific embodiment one, as follows Figures 2-4As shown, the flipping drive mechanism 2 includes a pair of drive shafts 201 respectively inserted through the opposite sides of the two side support beams 101, and transmission shafts 207 rotatably connected at both ends to the opposite sides of the two side support beams 101; the two drive shafts 201 are connected to the two side support beams 101 respectively by conventional roller bearings in the art; a movable strip 202 is rotatably connected to the adjacent end of each of the two drive shafts 201; the two movable strips 202 are respectively screwed to one opposite side of the base plate 3; the movable strips 202 A first gear 203 is provided between the first gear 203 and the adjacent side support beam 101; the first gear 203 is keyed to the outer periphery of the drive shaft 201; an internal gear ring 204 is coaxially provided on the outer periphery of the first gear 203; the internal gear ring 204 is fixed to the adjacent side support beam 101 by a plurality of mounting posts 205; the two ends of the mounting posts 205 are respectively inserted into the internal gear ring 204 and the side support beam 101, and the mounting posts 205 are interference-fitted with both the internal gear ring 204 and the side support beam 101; the internal gear ring 204 and the first gear ring 204 are keyed to the outer periphery of the drive shaft 201; an internal gear ring 204 is ...

The reducer 208 is connected to a first servo motor 209. The input end of the reducer 208 and the output shaft of the first servo motor 209 are connected by a conventional coupling in the art. The first servo motor 209 is screwed onto the housing of the reducer 208. Both ends of the drive shaft 207 are keyed to first pulleys 210. The two first pulleys 210 are respectively connected to second pulleys 211 via belt drive. The two second pulleys 211 are respectively keyed to the opposite ends of the two drive shafts 201. In use, the first servo motor 209 drives the two drive shafts 201 to rotate synchronously via the reducer 208, drive shaft 207, first pulleys 210 and second pulleys 211. This causes the two first gears 203 to drive the two pairs of second gears 206 to roll on the two internal gear rings 204, thereby realizing the rotation of the substrate 3 around the drive shaft 201. This not only ensures stable and labor-saving rotation but also effectively guarantees the rotation effect of the substrate 3.

[0036] Among them, such as Figures 5-6As shown, the feeding rack 4 includes an outer ring 401 and an inner ring 402 arranged coaxially; the outer ring 401 and the inner ring 402 are connected by a plurality of first connecting posts 403; the first connecting posts 403 are connected to the outer ring 401 and the inner ring 402 by welding; a plurality of support rods 404 are evenly welded along the axial direction on the inner ring 402; the plurality of support rods 404 are connected by a plurality of second connecting posts 405; the second connecting posts 405 are connected to the support rods 404 by welding; the ends of the plurality of support rods 404 away from the inner ring 402 are connected by a connecting plate 406; the connecting plate 406 is connected to the support rods 404 by welding; a lifting ring 407 is welded to the end face of the connecting plate 406 away from the inner ring 402. In use, the outer ring 401 and the inner ring 402 are placed on the substrate 3, and the inner ring 402 is locked by the positioning mechanism 5, so that the entire feeding rack 4 is stably installed on the substrate 3; when the feeding rack 4 is unlocked, the feeding rack 4 is removed from the substrate 3 by the lifting ring 407. Specific Implementation

[0037] Based on the second specific embodiment, as follows Figures 7-11 As shown, three first grooves 301 corresponding to the positioning mechanism 5 are evenly distributed on one surface of the substrate 3; the positioning mechanism 5 includes three cylindrical cams 501 arranged in a circumferential direction; the length direction of the cylindrical cams 501 is parallel to the length direction of the corresponding first grooves 301; the cylindrical cams 501 are located on the side of the first grooves 301 away from the feeding rack 4; both ends of the axle of the cylindrical cams 501 are rotatably connected to first support blocks 502; the first support blocks 502 are screwed to the substrate 3; a movable column 503 is slidably inserted into the working groove of the cylindrical cams 501; the movable column 503 is located away from the cylindrical cams 501. One end of the locating block 504 is inserted into the first slide groove 301 and welded thereon; the locating block 504 slides through the first slide groove 301; a first guide rod 505 parallel to the cylindrical cam 501 slides through the locating block 504; the two ends of the first guide rod 505 are respectively welded to the opposite two sides of the first slide groove 301; one end of the locating block 504 away from the movable column 503 extends out of the first slide groove 301, and this end has a receiving groove 506 corresponding to the inner ring 402; the receiving groove 506 has an arc-shaped structure; when the feeding rack 4 is placed on the substrate 3, the receiving groove 506 is located inside the inner ring 402. In use, rotating the cylindrical cam 501 drives the movable column 503 to move, causing the positioning block 504 to slide in the first slide groove 301 and bringing the receiving groove 506 close to the inner ring 402. When the movable column 503 moves to one end of the cylindrical cam 501, the inner ring 402 is in the receiving groove 506, thereby achieving the positioning of the feeding rack 4. This not only ensures accurate positioning of the feeding rack 4 but also enables rapid positioning of the feeding rack 4. Specific Implementation

[0038] Based on the third specific embodiment, as follows Figures 7-10 and Figures 12-13 As shown, a pair of second grooves 302 corresponding to the support mechanism 6 are symmetrically formed on one side of the substrate 3; the length directions of the two second grooves 302 are respectively parallel to the two diagonals of the substrate 3; the support mechanism 6 includes a lead screw 601 disposed between the two second grooves 302; the lead screw 601 is perpendicular to one side of the substrate 3; the lead screw 601 is disposed on the side of the second groove 302 away from the feeding rack 4; both ends of the lead screw 601 are rotatably connected to second support blocks 602; the second support blocks 602 are screwed to the substrate 3; a nut 603 is threaded onto the lead screw 601; one end of the nut 603... A second guide rod 604 perpendicular to the lead screw 601 is fixedly inserted; two sliding sleeves 605 are respectively slidably sleeved at both ends of the second guide rod 604; a bearing block 606 is fixedly sleeved on the outer periphery of each of the two sliding sleeves 605; the two bearing blocks 606 are respectively slidably inserted into the two second sliding grooves 302; a lifting plate 607 corresponding to the feeding rack 4 is screwed to the end of the bearing block 606 away from the sliding sleeve 605; the surface of the lifting plate 607 near the inner ring 402 is perpendicular to the length direction of the second sliding groove 302; and the surface of the lifting plate 607 near the inner ring 402 can be tangent to the circumferential side wall of the inner ring 402. In use, by rotating the lead screw 601 in the forward direction, the lead screw nut 603 causes the second guide rod 604 to move closer to the feeding rack 4, thereby causing the bearing block 606 to slide in the second slide groove 302 and the lifting plate 607 to move closer to the feeding rack 4; similarly, by rotating the lead screw 601 in the reverse direction, the lifting plate 607 is moved away from the feeding rack 4. This not only prevents the feeding rack 4 from affecting the placement of the wire coil on the feeding rack 4, but also stably constrains the wire coil on the feeding rack 4 during the flipping process of the feeding rack 4. Specific Implementation

[0039] Based on specific embodiment four, as follows Figures 7-12As shown, the linkage mechanism 7 includes a second servo motor 701 whose output shaft is coaxially connected to one end of the lead screw 601, and a mounting shaft 702 disposed between multiple cylindrical cams 501; the output shaft of the second servo motor 701 is connected to the lead screw 601 via a conventional coupling in the art; the second servo motor 701 is screwed to the base plate 3; the mounting shaft 702 is perpendicular to the cylindrical cams 501; one end of the mounting shaft 702 is rotatably connected to the base plate 3; a conventional one-way bevel gear 703 and a first bevel gear 704 are keyed side by side on the mounting shaft 702; multiple second bevel gears 705 corresponding to the cylindrical cams 501 are meshed on the one-way bevel gears 703; the second bevel gears 705 are keyed to one end of the axle of the cylindrical cams 501; a third bevel gear 706 corresponding to the lead screw 601 is meshed on the first bevel gear 704; the third bevel gear 706 is keyed to the other end of the lead screw 601. When the feeding rack 4 is placed vertically on the substrate 3, the output shaft of the second servo motor 701 rotates in the reverse direction. At this time, the lead screw 601 rotates in the reverse direction, and the lifting plate 607 gradually moves away from the feeding rack 4. Simultaneously, the cylindrical cam 501 is driven to rotate via the lead screw 601, the third bevel gear 706, the first bevel gear 704, the mounting shaft 702, the one-way bevel gear 703, and the second bevel gear 705. This causes the movable column 503 to move to one end of the cylindrical cam 501, and the inner ring 402 is placed in the receiving groove 506. This achieves the positioning mechanism 5 locking the feeding rack 4 on the substrate 3 and maximizing the distance between the supporting mechanism 6 and the feeding rack 4. When the wire is wound onto the horizontally set feeding rack 4, the output shaft of the second servo motor 701 rotates in the forward direction, and the lead screw 601 rotates in the forward direction to drive the feeding rack 4. When the lifting plate 607 approaches the feeding rack 4, the one-way bevel gear 703 does not rotate, and the positioning mechanism 5 always keeps the feeding rack 4 stably locked on the base plate 3. When the feeding rack 4 carrying the wire coil flips from a flat position to a vertical position, the output shaft of the second servo motor 701 rotates in the opposite direction. At this time, the lead screw 601 rotates in the opposite direction, and the lifting plate 607 gradually moves away from the feeding rack 4. At the same time, the lead screw 601, the third bevel gear 706, the first bevel gear 704, the mounting shaft 702, the one-way bevel gear 703 and the second bevel gear 705 drive the cylindrical cam 501 to rotate, causing the movable column 503 to move to the other end of the cylindrical cam 501, and the inner ring 402 to move away from the receiving groove 506, thereby realizing the positioning mechanism 5 unlocking the feeding rack 4 and the support mechanism 6 moving away from the feeding rack 4.
