Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, and in particular to an automatic lifting and turning mechanism for iron filings. Background Technology

[0002] During machining, machine tool cutting operations generate a large amount of iron filings. These filings are usually covered with impurities such as cutting fluid and oil, and improper handling can easily cause environmental pollution. Currently, most companies still use traditional manual methods to collect and transport iron filings. This involves manually pushing the filings cart in the workshop to a designated location, where they are then poured into a collection box or the inlet of a processing equipment using an iron filings lifting and turning device.

[0003] The existing iron filings are often unevenly distributed during the filling process, causing the container's center of gravity to deviate from its geometric center. This makes the supporting components prone to tilting and jamming during lifting, and also causes abnormal wear on the guide rails, affecting the equipment's operational stability and service life. Furthermore, the existing mechanism has a limited range of tilting angle adjustment, making it difficult to flexibly adjust the tilting angle according to actual needs, resulting in incomplete emptying of iron filings and a large amount of residue remaining in the container. Therefore, it is necessary to improve the existing iron filings lifting and tilting mechanism.

[0004] To address the shortcomings of the existing technology, the present invention provides an automatic lifting and turning mechanism for iron scrap packaging. Summary of the Invention

[0009] The adjustment assembly also includes a first guide wheel symmetrically rotatably connected to the outside of the support rod. A compensation slide cylinder is symmetrically fixedly connected to the outside of the support rod. A compensation slide rod is slidably arranged on the inside of the compensation slide cylinder.

[0010] The fixed cylinders are two symmetrically arranged, and a connecting column is fixedly installed between the two fixed cylinders. A second guide wheel is rotatably connected to the outer side of the fixed cylinder. Both the second guide wheel and the first guide wheel are movably arranged inside the lifting rail. An adjusting shaft is rotatably connected to the inner side of the connecting column. An adjusting gear is fixedly connected to one end of the adjusting shaft extending to the outer side of the connecting column. A baffle is fixedly installed on the top side of the lifting rail. An inclined rack is provided on the side of the baffle and is fixedly connected to the lifting rail. The inclined rack intermittently meshes with the adjusting gear.

[0011] A bevel gear disk is fixedly connected to the outer wall of the inner side of the fixed cylinder extending from the adjusting shaft. An adjusting bevel gear is meshed with the outer side of the bevel gear. An adjusting screw is fixedly connected to the inner side of the adjusting bevel gear. The adjusting screw is rotatably connected to the fixed cylinder. A limiting cylinder is fixedly connected to the outer side of the fixed cylinder. A threaded ring is provided on the inner side of the limiting cylinder for limiting and sliding. The threaded ring is threadedly connected to the adjusting screw. A movable cylinder is fixedly connected to the top of the threaded ring. The movable cylinder is provided on the inner side of the limiting cylinder for limiting and sliding. A hinge block is fixedly connected to the end of the movable cylinder. The hinge block is fixedly connected to the bearing plate.

[0012] The center of gravity compensation component also includes a motor frame fixedly installed at the bottom of the support plate. An adjusting motor is fixedly installed on one side of the motor frame. A driving bevel gear is fixedly installed at the output end of the adjusting motor. A driven bevel gear is meshed with the outer side of the driving bevel gear. A hollow shaft is fixedly connected to the inner side of the driven bevel gear.

The limiting transmission shaft is also fixedly connected to the adjusting plate.

[0016] The present invention has the following beneficial effects: In this invention, by setting up a center of gravity compensation component, the counterweight box slides along the arc of the adjustment rail to actively adjust the position of the center of gravity of the moving parts, effectively compensating for the uneven loading of iron filings in the scrap container that causes the center of gravity to be unbalanced, preventing the bearing plate from tilting and jamming or causing abnormal wear on the lifting rail during the lifting process, and ensuring the stability and safety of the vertical lifting stage.

[0017] In this invention, by adjusting the configuration of the components, when the support rod moves to the end of the tilting guide rail, the support rod and the fixed cylinder move relative to the bearing plate, pushing the bearing plate to tilt and achieve the tilting action of the shredder. Compared with the traditional tilting method, this structure allows the tilting angle of the shredder to have a larger adjustment range, effectively reducing shredder residue.

[0020] 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.

[0021] Example 1 like Figures 1-8 As shown, the present invention proposes an automatic lifting and turning mechanism for iron scrap packaging, including a base 1, a lifting mechanism on the top of the base 1, a bearing plate 3 installed on the lifting mechanism, a lifting rail 2 symmetrically fixedly connected to the top of the base 1, a tilting guide rail 20 fixedly connected to the top of the lifting rail 2, and an adjustment component on one side of the bearing plate 3. The adjustment component includes a support rod 31 and a fixed cylinder 38 movably disposed inside the lifting rail 2. The support rod 31 and the fixed cylinder 38 have relative movement with respect to the bearing plate 3. A center of gravity compensation component is provided on the support plate 3. The center of gravity compensation component includes a fixed plate 312 fixedly connected to the top of the support plate 3. An adjustment plate 311 is rotatably provided on the top of the fixed plate 312. Several limiting heads 3121 are circumferentially equidistantly slidable between the fixed plate 312 and the adjustment plate 311. A debris container 30 is provided for centering and limiting between the several limiting heads 3121. An adjustable arc rail 315 is fixedly installed at the bottom of the bearing plate 3, and a counterweight box 319 is slidably mounted on the adjustable arc rail 315.

[0022] Firstly, this design addresses the issue that the center of gravity of the iron filings in the scraper 30 is not on the axis of the scraper 30 during the filling process. By setting up a center of gravity compensation component, the scraper 30 is first placed on the support plate 3, and the central axis of the scraper 30 coincides with the center of gravity of the support plate 3. By driving the counterweight box 319 to slide along the arc of the adjusting arc rail 315, the position of the center of gravity of the entire moving part is actively adjusted, thereby effectively compensating for the off-center center of gravity, preventing the support plate 3 from tilting and jamming during the rising process or causing abnormal wear on the lifting rail 2, and ensuring the stability and safety of the vertical lifting stage. Furthermore, through the adjustment components, when the support rod 31 moves to the end of the tilting guide rail 20, the support rod 31 and the fixed cylinder 38 can generate relative movement with the bearing plate 3. This relative displacement pushes the bearing plate 3 to tilt, thereby realizing the tilting action of the shredder 30. Compared with the traditional tilting method, the tilting angle of the shredder 30 in this design has a large adjustment range.

[0023] Example 2 like Figures 7-8 As shown, based on the above embodiments, in this embodiment, the center of gravity compensation component further includes a motor frame 316 fixedly installed at the bottom of the bearing plate 3. A limit motor 318 is fixedly connected to the bottom of the motor frame 316. A limit transmission shaft 325 is fixedly connected to the output end of the limit motor 318. The limit transmission shaft 325 is rotatably connected to the inner side of the hollow shaft 324.

[0024] The adjusting plate 311 has several driving grooves 3110 that are equidistantly spaced around the circumference, and the fixed plate 312 has several limiting grooves 3120 that are equidistantly spaced around the circumference. The limiting head 3121 is slidably positioned inside the driving grooves 3110 and the limiting grooves 3120. The limiting drive shaft 325 extends to one end of the outer side of the bearing plate 3 and is rotatably connected to the fixed plate 312. The limiting drive shaft 325 is also fixedly connected to the adjusting plate 311.

[0025] Furthermore, the operator hoists the scraper 30 filled with iron filings onto the fixed plate 312 on top of the support plate 3. At this time, the limit motor 318 is started. The output end of the limit motor 318 drives the limit transmission shaft 325 to rotate independently inside the hollow shaft 324. Since the limit transmission shaft 325 is fixedly connected to the adjustment plate 311, the adjustment plate 311 rotates accordingly. Furthermore, during the rotation process, the drive groove 3110 on the adjusting plate 311 drives the limiting head 3121 to slide radially inward along the limiting groove 3120 of the fixed plate 312. Multiple limiting heads 3121 move centripetally at the same time, centering and clamping the slag container 30 to achieve rapid positioning and locking, preventing the container body from loosening during subsequent flipping.

[0026] An adjusting motor 317 is fixedly installed on one side of the motor frame 316. An active bevel gear 323 is fixedly installed at the output end of the adjusting motor 317. A driven bevel gear 322 is meshed with the outer side of the active bevel gear 323. A hollow shaft 324 is fixedly connected to the inner side of the driven bevel gear 322. The hollow shaft 324 is rotatably connected to the motor frame 316 and the bearing plate 3.

[0027] The hollow shaft 324 extends to the outside of the motor frame 316 and is fixedly connected to the drive plate 320. The inner side of the adjusting arc rail 315 is slidably provided with an arc-shaped slider 321. The drive plate 320 is fixedly connected to the arc-shaped slider 321, and the counterweight box 319 is fixedly connected to the bottom of the drive plate 320.

[0028] Furthermore, since the iron filings in the scraper 30 are unevenly distributed during filling, the bearing plate 3 will be unbalanced on one side. At this time, the adjusting motor 317 is started, and through the transmission of the bevel gear pair, hollow shaft 324 and drive plate 320, the counterweight box 319 is driven to slide along the adjusting arc rail 315 to the opposite position of the unbalanced side, so that the center of gravity of the bearing plate 3 and the center of gravity of the scraper 30 are as close as possible to the same axis. Before the lifting action is started, the unbalanced load torque is eliminated in advance, thereby avoiding abnormal wear or jamming between the two guide wheels and the lifting rail 2 due to unbalanced load when the bearing plate 3 rises vertically in the subsequent process. This ensures that the initial posture of the entire lifting stage is stable and the force is balanced.

[0029] Example 3 like Figures 1-6 As shown, based on Embodiment 1, in this embodiment, the lifting mechanism includes lifting brackets 10 symmetrically and fixedly connected to the top of the base 1, lifting drive shafts 12 symmetrically and rotatably connected to the two lifting brackets 10, lifting sprockets 13 symmetrically and fixedly connected to the outer side of the lifting drive shafts 12, a lifting chain 11 sleeved and connected between the two lifting sprockets 13, a lifting motor 14 fixedly installed on the outer side of the base 1, the output end of the lifting motor 14 being connected to the lifting drive shafts 12, and a connecting plate 313 fixedly connected to the lifting sprockets 13 and the fixed cylinder 38.

[0030] Furthermore, the lifting process is achieved by starting the lifting motor 14, which drives the lifting sprockets 13 on both sides to rotate synchronously through the lifting drive shaft 12. The lifting sprockets 13 drive the lifting chain 11 to move upward, and the lifting chain 11 drives the fixed cylinder 38 and the entire bearing plate 3 to move vertically upward along the lifting rail 2 through the connecting plate 313.

[0031] Furthermore, during this process, the first guide wheel 32, which is symmetrically arranged on the outside of the support rod 31, and the second guide wheel 39, which is on the outside of the fixed cylinder 38, both roll against the inside of the lifting rail 2 to ensure that the bearing plate 3 runs smoothly and without deviation.

[0032] Limiting components are provided on the two tilting guide rails 20. The limiting components include a limiting cylinder 23 installed at the bottom of the tilting guide rail 20, and a limiting block 24 is fixedly installed at the output end of the limiting cylinder 23. The limiting block 24 slides relative to the tilting guide rail 20.

[0033] Furthermore, when the two first guide wheels 32 move onto the tilting guide rail 20, the entire support plate 3 begins to tilt. At this time, when the first guide wheel 32 coincides with the end of the tilting guide rail 20, the limiting cylinder 23 set at the bottom of the tilting guide rail 20 extends and pushes the limiting block 24 into the limiting groove of the tilting guide rail 20 to mechanically limit the second guide wheel 39.

[0034] The adjustment assembly also includes a first guide wheel 32 symmetrically rotatably connected to the outside of the support rod 31, a compensation slide cylinder 34 symmetrically fixedly connected to the outside of the support rod 31, a compensation slide rod 33 slidably arranged on the inside of the compensation slide cylinder 34, and a compensation slide rod 33 fixedly connected to the bearing plate 3.

[0035] Two fixed cylinders 38 are symmetrically arranged, and a connecting column 310 is fixedly installed between the two fixed cylinders 38. A second guide wheel 39 is rotatably connected to the outer side of the fixed cylinder 38. The second guide wheel 39 and the first guide wheel 32 are both movably arranged inside the lifting rail 2. An adjusting shaft 314 is rotatably connected to the inner side of the connecting column 310. An adjusting gear 37 is fixedly connected to one end of the adjusting shaft 314 extending to the outer side of the connecting column 310. A baffle 21 is fixedly installed on the top side of the lifting rail 2. An inclined rack 22 is fixedly connected to the lifting rail 2 on the side of the baffle 21. The inclined rack 22 intermittently meshes with the adjusting gear 37.

[0036] An adjusting shaft 314 extends to the outer wall of the inner side of the fixed cylinder 38 and is fixedly connected to a bevel gear 326. An adjusting bevel gear 327 is meshed with the outer side of the bevel gear 326. An adjusting screw 328 is fixedly connected to the inner side of the adjusting bevel gear 327. The adjusting screw 328 is rotatably connected to the fixed cylinder 38. A limiting cylinder 36 is fixedly connected to the outer side of the fixed cylinder 38. A threaded ring 330 is provided on the inner side of the limiting cylinder 36 for limiting and sliding. The threaded ring 330 is threadedly connected to the adjusting screw 328. A movable cylinder 329 is fixedly connected to the top of the threaded ring 330. The movable cylinder 329 is provided on the inner side of the limiting cylinder 36 for limiting and sliding. A hinge block 35 is fixedly connected to the end of the movable cylinder 329. The hinge block 35 is fixedly connected to the bearing plate 3.

[0037] Furthermore, when the first guide wheel 32 coincides with the end of the tilting guide rail 20, the adjusting gear 37 fixedly installed at the end of the adjusting shaft 314 begins to mesh with the tilting rack 22; Furthermore, as the fixed cylinder 38 continues to be pulled upward, the adjusting gear 37 is forced to rotate in the forward direction due to the meshing action of the inclined rack 22. The adjusting gear 37 drives the adjusting shaft 314 to rotate. The adjusting shaft 314 drives the adjusting bevel gear 327, which meshes with it, to rotate through the bevel gear disk 326 on its outer wall. The adjusting bevel gear 327 drives the adjusting screw 328 to rotate inside the fixed cylinder 38. The threaded ring 330 drives the moving cylinder 329 to extend outward along the limiting cylinder 36. The moving cylinder 329 pushes the bearing plate 3 through the hinge block 35 at its end, causing the bearing plate 3 to undergo lateral displacement relative to the support rod 31.

[0038] Since the first guide wheel 32 is already engaged in the tilting guide rail 20, while the second guide wheel 39 is still constrained by the vertical direction of the lifting rail 2, the bearing plate 3 will tilt and flip with the first guide wheel 32 as the fulcrum after being pushed by the hinge block 35. At the same time, the compensating slide rod 33 maintains a sliding fit in the compensating slide cylinder 34, providing a guiding margin for the flipping of the bearing plate 3. Through this adjustment method, compared with the traditional tilting method, it has a larger tilting angle adjustment range and reduces the residue in the debris container 30.

[0039] Furthermore, after the iron filings are completely dumped, the lifting motor 14 reverses, and the support plate 3 begins to descend. The adjusting gear 37 moves down and meshes with the inclined rack 22 in the opposite direction, driving the adjusting screw 328 to reverse, the moving cylinder 329 retracts, the support plate 3 gradually returns to the center, the limit cylinder 23 drives the limit block 24 to retract and release the limit, the second guide wheel 39 disengages from the dumping guide rail 20 and returns to the lifting rail 2. When the support plate 3 descends to the bottom of the base 1, the limit motor 318 reverses, the limit head 3121 releases radially, and the empty scrap container 30 can be unloaded, completing a full work cycle.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
