Description

Technical Field

[0001] This application relates to the field of roll material feeding equipment, and in particular to a production feeding device for mounting rails. Background Technology

[0002] The casting material for the mounting rail is made from rolled steel coils that are uncoiled by an uncoiler and then conveyed to a punching device to complete the production feeding process.

[0003] Existing uncoiling equipment, after placing the coil on the outer wall of the unwinding mechanism, uses a pneumatic rotating arm or a manual limit bracket to limit the outer wall of the coil to prevent horizontal deviation during feeding. The pneumatic rotating arm requires an additional drive source and structural arrangement, and places higher demands on the operator's technical skills. The manual installation of the limit bracket requires the operator to repeatedly disassemble and install the bracket each time the steel coil is used and rewound. This highly repetitive labor can easily lead to repetitive strain injuries over time, and can also cause injury to workers during the tightening process, posing safety risks. Utility Model Content

[0004] To improve the cumbersome operation of limiting the roll material during the feeding process, this application provides a production feeding device for mounting rails.

[0005] The technical solution of the installation rail production feeding device provided in this application is as follows:

[0006] A feeding device for mounting rail production includes a control device, wherein an expansion and contraction drum is provided at one output shaft end of the control device, and an opening and closing adjustment mechanism is provided on the outer wall of the expansion and contraction drum.

[0007] The opening and closing adjustment mechanism includes a rack disposed on the outer wall of the expansion and contraction drum. The rack is used to drive the gear to rotate. A rotating rod is disposed in the middle of the gear to drive the rotating bar to rotate. A connecting plate two is fixedly disposed at the end of the rotating bar to drive the limit frame to rotate. A sliding rod is movably disposed on the side wall of the connecting plate two to drive the limit frame to slide horizontally. A roll material is disposed on one side of the connecting plate two. An inner support member is disposed at the top of the rotating rod. A lead screw is movably disposed inside the inner support member one to drive the sliding block one to move horizontally. A knob is fixedly disposed at the end of the lead screw to rotate synchronously with the lead screw. A connecting bar is fixedly disposed on one side wall of the sliding block to drive the sliding block two to move horizontally. A spring is movably disposed on the inner wall of the sliding block two to drive the sliding column to move horizontally.

[0008] By adopting the above technical solution, the rack drives the gear to rotate, the gear drives the rotating rod to rotate through the rotating bar, and the rotating rod drives the limiting frame to change from a vertical state to a horizontal state through the connecting plate two. Therefore, when winding, there is no need to remove the limiting frame. Simply change the limiting frame to a horizontal state and pass it through the middle of the roll to complete the winding. The inner support member one is driven to expand outward by the expansion and contraction of the roll drum. The knob drives the lead screw to rotate, so that the sliding column engages with the limiting frame. The limiting frame and the sliding block two move horizontally in sync, so that the limiting frame fits and fixes the side wall of the roll precisely, avoiding accidental pinching caused by manual fixing.

[0009] Preferably, the opening and closing adjustment mechanism further includes a movable seat fixedly connected to the outer wall of the expansion and contraction drum. A connecting rod is movably arranged on the side wall of the movable seat. A sliding seat is movably arranged at the end of the connecting rod away from the movable seat. A rotating disk is slidably connected to the outer wall of the sliding seat. The middle part of the rotating disk is fixedly connected to the output shaft of the control device. A connecting plate is fixedly connected to the side wall of the sliding seat. A rotating rod is movably passed through one side wall of the connecting plate. The rotating rod is fixedly passed through the middle of a gear. A rack that meshes with the side wall of the gear and fits against the side wall of the sliding seat is engaged with the side wall of the gear. A limit plate is fixedly connected to the top of the rack.

[0010] By adopting the above technical solution, the horizontal movement of the moving seat drives the sliding seat to move vertically towards the axis of the expansion and contraction drum through the connecting rod. This controls the horizontal movement of the expansion and contraction drum to provide internal support for the roll material. The rack is limited by the connecting plate and can only move vertically, thus avoiding structural interference.

[0011] Preferably, a support plate 1 that is fixedly connected to the bottom of an inner support member 1 is movably passed through the outer wall of the rotating rod, a rotating bar is fixedly passed through the outer wall of the rotating rod, a connecting plate 2 is fixedly connected to the end of the rotating bar away from the rotating rod, and a sliding rod is movably passed through the side wall of the connecting plate 2.

[0012] By adopting the above technical solution, the sliding rod is limited by the second connecting plate and can only move linearly along the direction of the rod. The sliding rod cannot rotate, thereby avoiding the misalignment and sliding connection between the limiting frame and the sliding groove.

[0013] Preferably, the end of the sliding rod away from the second connecting plate is fixedly connected to the second limiting plate, the side wall of the second connecting plate is fixedly connected to the synchronization plate, the other end of the sliding rod away from the second limiting plate is fixedly connected to the limiting frame, the top of the sliding seat is fixedly connected to the bottom of the first inner support member, and the top of the first inner support member is provided with a sliding groove.

[0014] By adopting the above technical solution, the sliding rod is jointly limited by the limiting frame and the second limiting plate, thereby preventing the sliding rod from separating from the second connecting plate. The cross-sectional area of ​​the sliding groove is consistent with the bottom size of the limiting frame, thereby avoiding insufficient stability of the limiting frame.

[0015] Preferably, a through groove is provided through the inner sidewall of the sliding groove, and the end of the inner support member 1 away from the connecting plate 2 is fixedly connected to the inner support member 2 which is fixedly connected to the top of the sliding seat. A lead screw is movably passed through one side wall of the inner support member, and a support plate 2 which is fixedly connected to the inner wall of the inner support member 1 is movably passed through the outer wall of the lead screw.

[0016] By adopting the above technical solution, the curvature of the second inner support component is consistent with that of the first inner support component, thereby improving the structural integrity. The lead screw remains in a horizontal state, thus ensuring that the first sliding block always maintains horizontal movement.

[0017] Preferably, a knob is fixedly connected to the end of the lead screw away from the second support plate, a sliding block is threaded through the outer wall of the lead screw, a connecting strip is fixedly connected to both sides of the sliding block, and a second sliding block is fixedly connected to the end of the connecting strip away from the first sliding block.

[0018] By adopting the above technical solution, the knob and the lead screw are kept on the same axis, which makes the rotation more stable. The connecting strips are symmetrically located on both sides of the sliding block one, which facilitates the movement of the sliding block two.

[0019] Preferably, an inclined block is fixedly connected to the inner sidewall of the through groove, a limiting strip that fits against the sidewall of the sliding block is fixedly connected to the bottom of the inner wall of the inner support member, and a horizontal plate that is fixedly connected to the inner wall of the inner support member is provided on the top of the sliding block.

[0020] By adopting the above technical solution, the limiting strip and the horizontal plate together limit the sliding block two, thereby avoiding the problem of the sliding block two wobbling during horizontal movement.

[0021] Preferably, the limiting frame has an insertion slot on the side that fits with the through slot, and the sliding block two has a sliding column slidably connected to the side near the inclined block. The end of the sliding column away from the inclined block is fixedly connected to a spring that is fixedly connected to the inner wall of the sliding block two.

[0022] By adopting the above technical solution, the sliding column is engaged with the insertion slot by the spring, which facilitates the horizontal movement of the limiting frame by the sliding column.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The rack drives the gear to rotate, which in turn drives the rotating bar to rotate synchronously. The rotating bar will drive the limit frame and the connecting plate to rotate synchronously. This allows the rack to drive the limit frame from a vertical state to a horizontal state when the roll material needs to be rolled up, thus preventing interference with the roll material loading. Furthermore, the limit frame does not need to be disassembled by the operator when the roll material is being rolled up, making the device more integrated and reducing the number of operation steps for the operator.

[0025] 2. The lead screw drives the sliding block one to move horizontally, which in turn drives the sliding block two to move horizontally in sync. The sliding column extends from the inner wall of the sliding block two and engages with the side wall of the limiting frame. As the sliding block two continues to move horizontally, it drives the limiting frame to move horizontally in sync, thus moving the limiting frame closer to the outside of the roll material and limiting the side wall of the roll material. By rotating the knob, the operator can conveniently and accurately adjust the horizontal position of the limiting frame, thereby achieving the side limiting of the roll material.

[0040] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0041] This application discloses a rail production feeding device.

[0042] Reference Figure 1 A feeding device for installing rails includes a control device 1. One output shaft of the control device 1 is fixedly connected to an expanding and contracting drum 11, thereby driving the expanding and contracting drum 11 to move horizontally via hydraulic expansion. An opening and closing adjustment mechanism 2 is provided on the outer wall of the expanding and contracting drum 11. The opening and closing adjustment mechanism 2 also includes a movable seat 21 fixedly connected to the outer wall of the expanding and contracting drum 11. The movable seat 21 is centrally symmetrically fixedly connected to the outer wall of the expanding and contracting drum 11. A shaft is fixedly connected to the side wall of the movable seat 21, and the shaft is rotatably connected to a connecting rod 22, thereby allowing the movable seat 21 and the connecting rod 22 to be rotatably connected. The end of the connecting rod 22 away from the movable seat 21 is rotatably connected to… There is a shaft 2, and the side wall of the sliding seat 23 is fixedly connected to the shaft 2, so that the sliding seat 23 is rotatably connected to the connecting rod 22. The side wall of the rotating disk 24 is provided with a sliding groove 1, and the outer wall of the sliding seat 23 is slidably connected to the sliding groove 1, so that the sliding seat 23 is slidably connected to the rotating disk 24. A horizontal bar (not shown in the figure) is fixedly connected to the end of the sliding seat 23 near the control device 1, so as to limit the horizontal movement of the sliding seat 23. So when the moving seat 21 moves horizontally, the moving seat 21 drives the connecting rod 22 from vertical to inclined state, and the sliding seat 23 can only move longitudinally, so as to drive the sliding seat 23 to perform the internal support step of the roll material 3.

[0043] Before the installation of the rails in the factory production workshop, the staff first control the expansion and contraction drum 11 to move horizontally to the side away from the control device 1 through the control device 1, so that the moving seat 21 moves horizontally in sync. The moving seat 21 will drive the connecting rod 22 from the vertical state to the inclined state, thereby driving the sliding seat 23 to move longitudinally in the direction of the center of the expansion and contraction drum 11, thus changing to the inward winding state.

[0044] Reference Figures 2-4The rotating disk 24 is fixedly connected to the output shaft of the control device 1. The control device 1 controls the horizontal movement of the expanding and contracting drum 11 hydraulically. At the same time, the control device 1 drives the rotating disk 24 to rotate through the built-in servo motor, so that the rotating disk 24 and the expanding and contracting drum 11 rotate synchronously when the unwinding step is performed. The connecting plate 25 is fixedly connected to the side wall of the sliding seat 23. The side wall of the connecting plate 25 has a circular hole. The rotating rod 26 moves through the circular hole, so that the rotating rod 26 is rotatably connected to the connecting plate 25. The middle of the gear 27 is fixedly connected to the rotating rod 26, and the two sides of the gear 27 are attached to the connecting plate 25. The teeth on the side wall of gear 27 mesh with the teeth on the side wall of rack 28. The side of rack 28 away from gear 27 is in contact with the outer wall of sliding seat 23. Rack 28 always remains vertical. As sliding seat 23 moves, rack 28 will contact the top of moving seat 21. The top of rack 28 is fixedly connected to the bottom of limiting plate 29. The bottom of limiting plate 29 is in contact with the top of connecting plate 25, so that rack 28 cannot continue to move downward. A circular hole 2 is provided through the side wall of support plate 210. The outer wall of rotating rod 26 moves through the circular hole 2, so that rotating rod 26 is rotatably connected to support plate 210.

[0045] When the sliding seat 23 moves longitudinally towards the center, since the moving seat 21 moves laterally and the sliding seat 23 moves longitudinally, the sliding seat 23 will drive the connecting plate 25, gear 27, rack 28 and other components to move downward synchronously. The bottom of the rack 28 will contact the top of the moving seat 21 and be pushed upward by the moving seat 21. As a result, the rack 28 will move vertically upward, thereby causing the rack 28 to drive the gear 27 to rotate through meshing. The gear 27 will drive the rotating rod 26 to rotate synchronously.

[0046] Reference Figure 5Support plates 210 are symmetrically located on both sides of the rotating rod 26. The top of support plates 210 is fixedly connected to the bottom of the inner support member 217, thereby improving the stability of the structure. A circular hole 3 is provided through the side wall of the rotating bar 211, and the outer wall of the rotating rod 26 is fixedly connected to the circular hole 3, so that the rotating rod 26 and the rotating bar 211 are fixedly connected. When the rotating rod 26 rotates, the rotating bar 211 will rotate synchronously. The end of the rotating bar 211 away from the rotating rod 26 is fixedly connected to the side wall of the connecting plate 212. The connecting plate 212 is in contact with the side wall of the inner support member 217. A square hole is provided on the side wall of the connecting plate 212, and the sliding rod 213 moves through the square hole, so that the sliding rod 213 is slidably connected to the connecting plate 212. One end of plate 212 is fixedly connected to the side wall of limiting plate 214. The area of ​​the connection surface between limiting plate 214 and sliding rod 213 is larger than the area of ​​the square hole, so that sliding rod 213 always maintains a sliding connection with connecting plate 212. The side wall between the two connecting plates 212 is fixedly connected to both ends of synchronous plate 215. The side wall of synchronous plate 215 is in contact with inner support member 217, so that the two connecting plates 212 on both sides maintain synchronicity. The other end of sliding rod 213 away from limiting plate 214 is fixedly connected to the side wall of limiting frame 216. The limiting frame 216 is A-shaped. When the limiting frame 216 is in a horizontal state, the limiting frame 216 will be lower than the top of inner support member 217, so that the roll material 3 can pass smoothly through inner support member 217.

[0047] When gear 27 drives rotating rod 26 to rotate, rotating rod 26 will drive rotating bar 211 to rotate, rotating bar 211 from a horizontal state to a vertical state. Rotating bar 211 will drive connecting plate 212 to rotate synchronously, connecting plate 212 will drive sliding rod 213 to rotate synchronously, sliding rod 213 will drive limiting frame 216 to rotate synchronously, so that limiting frame 216 changes from a vertical state to a horizontal state. Limiting frame 216 will be lower than the top arc surface of inner support member 217. Then, the worker will use hoisting equipment to put the roll material 3 on the outer wall of inner support member 217 and inner support member 220, so that the side of roll material 3 near rotating disk 24 is aligned with the side wall of rotating disk 24. Then, the worker will drive expansion and contraction through control device 1. The drum 11 moves horizontally, thereby driving the movable seat 21 to move horizontally in the opposite direction. The connecting rod 22 will change from an inclined state to a vertical state, thereby causing the inner support member 1 217 to drive the inner support member 220 to open outward, thus providing internal support for the inner wall of the roll 3. When the inner support member 1 217 and the inner support member 220 move away from the center of the expanding and contracting drum 11, the rack 28 will release its contact with the movable seat 21. The rack 28 will move vertically downward according to its own weight, thereby driving the gear 27 to rotate in the opposite direction. The gear 27 will drive the rotating rod 26 to rotate synchronously. The rotating rod 26 will drive the limiting frame 216 to change from a horizontal state to a vertical state, and drive the limiting frame 216 to engage with the sliding groove 218, thereby facilitating subsequent structural movements.

[0048] Reference Figures 6-7 The bottom of the inner support member 217 is fixedly connected to the top of the sliding seat 23. The inner support member 217 has a cavity inside. The sliding groove 218 is not through-hole opened at the top of the inner support member 217. The sliding groove 218 is slidably connected to the limiting frame 216. The through groove 219 is horizontally through-hole opened on the inner sidewall of the sliding groove 218. Figure 4 As shown, the end of the inner support member 217 away from the connecting plate 212 is fixedly connected to the inner support member 220. The bottom of the inner support member 220 is fixedly connected to the top of the sliding seat 23. The side of the inner support member 220 near the rotating disk 24 is in contact with the rotating disk 24. The outer wall of the inner support member 220 is in contact with the inner wall of the roll material 3. A circular hole 4 is opened through the side wall of the inner support member 217. The lead screw 221 moves through the circular hole 4, so that the lead screw 221 is rotatably connected to the inner support member 217. A circular hole 5 is opened through the side wall of the support plate 222. The outer wall of the lead screw 221 moves through the circular hole 5, so that the lead screw 221 is rotatably connected to the support plate 222. The upper and lower ends of the support plate 222 are fixedly connected to the inner wall of the inner support member 217. The end of the lead screw 221 away from the support plate 222 is fixedly connected to the knob 223. The side wall of the knob 223 is provided with friction texture to facilitate the operator to rotate the knob 223.

[0049] After the limit frame 216 is engaged with the sliding groove 218, the operator turns the knob 223. The knob 223 will drive the lead screw 221 to rotate, the lead screw 221 will drive the first sliding block 224 to move horizontally, the first sliding block 224 will drive the connecting bar 225 to move horizontally synchronously, and the connecting bar 225 will drive the second sliding block 226 to move horizontally synchronously.

[0050] Reference Figure 8 A threaded hole is provided through the side wall of the sliding block 224, and the threaded rod 221 is threaded through the threaded hole on its outer wall, thus connecting the threaded rod 221 to the sliding block 224. The rotation of the threaded rod 221 drives the sliding block 224 to move horizontally. Both sides of the sliding block 224 are fixedly connected to the connecting strip 225. The connecting strip 225 is installed at an angle, so that the connecting strip 225 does not contact the inner wall of the inner support member 217, avoiding structural interference. The connecting strip 225 is located away from the sliding block 224. One end is fixedly connected to the second sliding block 226. The bottom of the second sliding block 226 is in contact with the bottom of the inner wall of the first inner support 217. The inner side wall of the through groove 219 is fixedly connected to the vertical surface of the inclined block 227. The side of the first inner support 217 near the second sliding block 226 is an inclined surface. The bottom of the inner wall of the first inner support 217 is fixedly connected to the bottom of the limiting strip 228. The side of the limiting strip 228 near the second sliding block 226 is in contact with the side wall of the second sliding block 226. The top of the second sliding block 226 is in contact with the bottom of the horizontal plate 229.

[0051] When the sliding block 226 moves horizontally, it will drive the internal sliding column 231 and spring 232 to move synchronously. When the sliding column 231 is located at... Figure 9 When in the position shown, the spring 232 is in a compressed state, and the spring 232 has a thrust on the sliding post 231, so that when the connecting bar 225 drives the sliding block 226 to move horizontally, the sliding post 231 always fits against the inclined surface of the inclined block 227.

[0052] Reference Figure 9 The horizontal plate 229 is fixedly connected to the inner wall of the inner support member 217 at both ends, and the insertion slot 230 is not through-hole opened on the side where the limiting frame 216 and the through slot 219 fit together. Figure 8 As shown, the side of the insertion slot 230 away from the sliding rod 213 is a horizontal surface, and the side of the insertion slot 230 near the sliding rod 213 is an inclined surface. The inclined surface of the sliding rod 213 and the inclined surface of the inclined block 227 have the same inclination angle. The sliding block 226 near the inclined block 227 has a non-through circular hole 6. The sliding column 231 is slidably connected to the inside of the circular hole 6. The end of the sliding column 231 away from the inclined block 227 is fixedly connected to a spring 232. The end of the spring 232 away from the sliding column 231 is fixedly connected to the inner wall of the sliding block 226. The end of the sliding column 231 near the inclined block 227 is a smooth surface. The top of the limiting strip 228 is lower than the bottom height of the circular hole 6. The top of the synchronization plate 215 and the knob 223 maintain a distance of 1-1.5cm to avoid structural interference.

[0053] As the sliding column 231 continues to move, it slides along the inclined surface of the inclined block 227 into the insertion slot 230, limiting the limit frame 216 and preventing it from rotating. The limit frame 216 moves horizontally in sync with the second sliding block 226, locking it in place. The sliding column 231 then drives the limit frame 216 to move horizontally, causing the sliding rod 213 to slide horizontally. The sliding rod 213 is the same length as the sliding groove 218. By rotating the knob 223, the limit frame 216 moves horizontally to fit against the side wall of the roll material 3, thus cooperating with the rotating disk 24 to limit roll materials 3 of different widths from both sides. This improves structural flexibility while reducing the workload of workers. In the event of a power outage, workers can reset the second sliding block 226 by rotating the knob 223, and then manually pull the second limit plate 214 to release the side wall limitation.

[0054] The implementation principle of a rail-mounted production feeding device according to an embodiment of this application is as follows:

[0055] The operator controls the horizontal movement of the expansion drum 11 via control device 1, which in turn drives the moving seat 21 to move synchronously. This causes the connecting rod 22 to rotate from vertical to inclined, which in turn drives the sliding seat 23 to move longitudinally into the winding state. The sliding seat 23 drives the connecting plate 25, gear 27, and rack 28 downwards. After the rack 28 contacts the moving seat 21, it moves upwards, causing the gear 27 to rotate through meshing. This rotates the rotating rod 26, causing the rotating bar 211 to rotate vertically. Finally, the limiting frame 216 rotates horizontally and is lower than the top of the inner support member 217. Then, the roll material 3 is hoisted and placed outside the inner support member 217 and the inner support member 220, aligned with the side wall of the rotating disk 24. The expansion drum 11 is then driven to move in the opposite direction, causing the moving seat 21 to move in the opposite direction, which in turn drives the connecting rod 22 to rotate vertically. 2. When the structure is turned vertical, the inner support component 1 217 drives the inner support component 220 to open the inner wall of the supporting roll 3. At this time, the rack 28 is released from contact and moves downward, driving the gear 27 to rotate in the opposite direction. This causes the rotating rod 26 to drive the limiting frame 216 to turn vertical and engage with the sliding groove 218. Then, the knob 223 is turned to drive the lead screw 221 to rotate, causing the sliding block 1 224, the connecting bar 225, and the sliding block 226 to move horizontally. The sliding block 226 drives the sliding column 231 and the spring 232. The spring 232 pushes the sliding column 231 to slide against the inclined surface of the inclined block 227 to the insertion groove 230, driving the limiting frame 216 to move horizontally and adhere to the side wall of the roll 3. This works in conjunction with the rotating disk 24 to limit the movement, improving flexibility and reducing workload.

Various modifications and variations can be made to this application by those skilled in the art.
