Description

Technical Field

[0001] This invention relates to the field of machine tool processing equipment technology, and more specifically to a magnesium powder cutting waste collection device. Background Technology

[0002] Magnesium powder cutting waste collection devices are indispensable specialized equipment in the machining of magnesium alloys. They are mainly used to safely and efficiently collect and process waste generated during the cutting of magnesium alloys. Such devices are of great significance in preventing the risk of combustion caused by the accumulation of magnesium shavings, realizing resource recycling, and protecting the environment.

[0003] In the prior art, there are already some device designs involving the collection and sorting of machining center waste; for example, patent document CN222095493U discloses a machining center waste sorting and collection device, which includes a shell, a support plate disposed in the shell, and a feed inlet at the top; the device adopts a three-layer filter structure to classify and collect waste according to particle size, and the mesh size of each filter layer decreases from top to bottom; in order to facilitate rinsing the waste and reduce the dripping time of cutting fluid, the device is equipped with a water tank above the vibrating motor, which can spray cutting fluid onto the waste; at the same time, the heat energy generated when the vibrating motor is working is used to heat the water in the water tank to prevent the grease components in the cutting fluid from solidifying and improve the rinsing effect.

[0004] However, the existing sorting and collection devices still have obvious defects in actual use: although they attempt to achieve automatic sliding and grading of waste under gravity through multi-layered filters with tilted settings, this method also significantly shortens the effective residence time of waste on the screening surface. As a result, some smaller particles that should have been screened out are not fully separated and enter the corresponding collection box along with the larger particles, thereby reducing the accuracy of waste separation and the overall sorting effect. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, this application aims to solve how to coordinate the effective separation time and discharge switching time in the screening process of cutting waste, so as to achieve full separation and improve the accuracy of classification and collection.

[0006] This invention provides the following technical solution: a magnesium powder cutting waste collection device, which includes a housing and an oscillating screening system disposed inside the housing; the oscillating screening system includes a multi-stage material distribution unit and a composite drive mechanism for driving the multi-stage material distribution unit to achieve dynamic screening. The multi-stage material distribution unit consists of an upper screening mechanism and a lower screening mechanism arranged in an upper and lower layer. One end of the upper screening mechanism and the lower screening mechanism are meshed and rotatably installed in the housing. The other end of the upper screening mechanism is connected to an angle adjustment mechanism. By lifting one end of the upper screening mechanism through the angle adjustment mechanism, the upper screening mechanism and the lower screening mechanism are caused to rotate in opposite directions around the meshing end as the axis. When the upper screening mechanism changes from a horizontal state to a V-shape, the discharge ports of the upper screening mechanism and the lower screening mechanism tilt downward and point to both sides respectively, thereby automatically switching between dynamic screening and material distribution discharge modes.

[0007] Furthermore, the upper screening mechanism includes a first screening plate, one end of which is a discharge port, and the end near the discharge port is horizontally slidably connected to a first rotating bracket located at the bottom of the first screening plate. The first screening plate and the first rotating bracket are connected by an elastic telescopic member.

[0008] Furthermore, the first rotating support consists of a crossbeam and side plates fixed on both sides of the crossbeam and standing upwards. A shaft is fixed to the outside of the side plate, and the shaft is rotatably connected to a bearing fixed to the inner side wall of the box base. A first retraction wheel away from the discharge port is rotatably installed on the side wall of the first screening plate on the same side as the shaft. The first retraction wheel is elastically connected to the side plate of the first rotating support through an elastic telescopic member.

[0009] Furthermore, the lower screening mechanism includes a second screening plate that is centrally symmetrically distributed with the first screening plate. The discharge ports of the second screening plate and the first screening plate face to the sides respectively, and the far end of the discharge port of the second screening plate is vertically slidably engaged with a second rotating bracket located at its bottom. The second screening plate and the second rotating bracket are connected by a guide rod for transmission.

[0010] Furthermore, the second rotating bracket has the same structural composition as the first rotating bracket; the difference is that the side plate of the second rotating bracket is provided with a sliding groove, the guide rod moves through the sliding groove and is rigidly connected to the side wall of the second screening plate, and a second yielding wheel that can be pushed upward by the composite drive mechanism is rotatably installed on the side wall of the second screening plate on the same side as the guide rod.

[0011] Furthermore, the shaft ends of the first rotating bracket and the second rotating bracket are fixedly sleeved with an upper angle adjusting gear and a lower angle adjusting gear that mesh with each other, so as to adjust the included angle and thus control the inclination of their respective discharge ports.

[0012] Furthermore, the composite drive mechanism includes a turntable for laterally pressing the first retracting wheel, a swinging part that is linked to the turntable and can lift the second retracting wheel, a drive gear for driving the turntable to rotate, and a positioning bracket for fixing the position of the turntable and the drive gear; the rotating shaft of the drive gear is assembled with the output shaft of the servo motor.

[0013] Furthermore, the turntable is integrally injection molded from a gear disk, a pusher disk located on its inner side, and a connecting shaft that passes through the positioning bracket. The gear disk meshes with the drive gear, and the pusher disk extends outward from its periphery with a contact. When it rotates to its highest point, it abuts against the first retraction wheel. The length of the contact is positively correlated with the horizontal displacement of the first retraction wheel. Through the alternating action of multiple pusher disks and their cooperation with the elastic telescopic component, the horizontal oscillation screening action of the first screening plate is realized. A material spreading mechanism is installed on the first screening plate. The material spreading mechanism includes a scraper that can slide axially along the partition strip on the inner wall of the first screening plate. A connecting rod is connected above the scraper. The other end of the connecting rod extends outward parallel to the scraper. After bending and rotating downward above the turntable, it connects to the drive arm. The drive arm meshes with the gear disk and slides and engages with the limiting groove preset on the inner wall of the main box.

[0014] Furthermore, the swinging part includes a swing arm, one end of which is connected to the edge of the gear disk sidewall away from the pusher disk via a rotating shaft, and the other end is rotatably connected to the guide wheel; the sliding end of the guide wheel is nested in the guide groove of the track; when the gear disk rotates periodically in alternating directions, the swing arm swings up and down in a wave shape due to geometric constraints, and drives the second screening plate to complete the vertical oscillating screening action by intermittently pushing the second retracting wheel in coordination with gravity.

[0015] Furthermore, the angle adjustment mechanism includes a lifting arm located in the inner cavity of the box base, the bottom end of which is connected to a lever arm through a hinge point, and the other end of the lever arm is hinged to the first screening plate; a horizontally extendable sleeve is fixed to the side of the lifting arm near the inner wall of the box base, and a baffle is connected to the top end; the sleeve is poweredly connected to the telescopic cylinder on the outer wall of the box base.

[0016] The technical effects and advantages of this invention are as follows:

[0017] The automatic switching between dynamic screening and guided unloading modes is achieved through the lifting and lowering motion of the angle adjustment mechanism. In dynamic screening mode, the upper and lower screening mechanisms mesh and rotate towards each other to a horizontal position. The bidirectional alternating periodic rotation of the composite drive mechanism drives the first screening plate to oscillate horizontally and the second screening plate to oscillate vertically. At the same time, the scraper slides along the axial direction of the first screening plate to maintain the transmission adaptation between the spreading mechanism and the composite drive mechanism, achieving efficient screening. In guided unloading mode, the angle adjustment mechanism is lifted so that the upper and lower screening mechanisms rotate in opposite directions to form a V-shape. The scraper traction linkage extends to avoid interference. The wave-like swing of the swing arm drives the second screening plate to oscillate and unload. At the same time, the scraper reciprocates to clean the first screening plate, achieving directional discharge. This design has the advantages of high screening accuracy, fast unloading efficiency, and reliable mode switching. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The magnesium powder cutting waste collection device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figures 1 to 2 and Figure 9This invention provides a magnesium powder cutting waste collection device, which includes a housing 1 and an oscillating screening system disposed inside the housing 1; the oscillating screening system includes a multi-stage material distribution unit and a composite drive mechanism 4 for driving the multi-stage material distribution unit to achieve dynamic screening; the multi-stage material distribution unit is composed of an upper screening mechanism 2 and a lower screening mechanism 3 arranged in an upper and lower layer, one end of the upper screening mechanism 2 and the lower screening mechanism 3 are meshed and rotatably installed in the housing 1, and the other end of the upper screening mechanism 2 is connected to an angle adjustment mechanism 6. By lifting one end of the upper screening mechanism 2 through the angle adjustment mechanism 6, the upper screening mechanism 2 and the lower screening mechanism 3 are caused to rotate in opposite directions around the meshing end as the axis. When the upper screening mechanism 2 is rotated from a horizontal state to a V-shape, the discharge ports of the upper screening mechanism 2 and the lower screening mechanism 3 tilt downward and point to both sides respectively, thereby automatically switching between dynamic screening and material distribution discharge modes;

[0035] In this embodiment, it should be noted that the box base 1 includes a main box body 11, a fence 12 fixed to the top opening of the main box body 11, and a receiving funnel 13 fixed to the bottom of the fence 12. The fence 12 can receive waste generated during the cutting operation, and the receiving funnel 13 has an flared top and a retracted bottom, which can guide the waste from the fence 12 downward to the upper screening mechanism 2.

[0036] The main enclosure 11 is equipped with a flip-up or removable maintenance door on its side wall, which can be opened to inspect internal components in case of equipment failure.

[0037] A cutting device is provided above the fence 12 for cutting metal materials, and the cutting waste falls into the box base 1 under the action of gravity.

[0038] Reference Figures 3 to 14 The upper screening mechanism 2 includes a first screening plate 21. One end of the first screening plate 21 is a discharge port, and the end near the discharge port is horizontally slidably connected to a first rotating bracket 22 located at the bottom of the first screening plate 21. The first screening plate 21 and the first rotating bracket 22 are connected by an elastic telescopic member 23.

[0039] The first rotating support 22 consists of a crossbeam and side plates fixed on both sides of the crossbeam and standing upwards. A shaft is fixed to the outside of the side plate, and the shaft is rotatably connected to the shaft seat 111 fixed to the inner side wall of the box base 1. A first relief wheel 24 away from the discharge port is rotatably installed on the side wall of the first screening plate 21 on the same side as the shaft. The first relief wheel 24 is elastically connected to the side plate of the first rotating support 22 through an elastic telescopic member 23.

[0040] The lower screening mechanism 3 includes a second screening plate 31 that is centrally symmetrically distributed with the first screening plate 21. The discharge ports of the second screening plate 31 and the first screening plate 21 face to the sides respectively, and the second rotating bracket 32 ​​located at the bottom of the discharge port of the second screening plate 31 is vertically slidably engaged. The second screening plate 31 and the second rotating bracket 32 ​​are connected by a guide rod 33.

[0041] The second rotating bracket 32 ​​has the same structure as the first rotating bracket 22; the difference is that the side plate of the second rotating bracket 32 ​​is provided with a sliding groove, the guide rod 33 moves through the sliding groove and is rigidly connected to the side wall of the second screening plate 31, and a second yielding wheel 34 that can be pushed upward by the composite drive mechanism 4 is rotatably installed on the side wall of the second screening plate 31 on the same side as the guide rod 33.

[0042] The shaft ends of the first rotating bracket 22 and the second rotating bracket 32 ​​are fixedly sleeved with an upper angle adjusting gear 25 and a lower angle adjusting gear 35 that mesh with each other, so as to adjust the included angle and thus control the inclination of their respective discharge ports.

[0043] The composite drive mechanism 4 includes a turntable part 41 for laterally pressing the first retracting wheel 24, a swing part 42 that is linked to the turntable part 41 and can lift the second retracting wheel 34, a drive gear 43 that drives the turntable part 41 to rotate, and a positioning bracket 44 that fixes the position of the turntable part 41 and the drive gear 43; the rotating shaft of the drive gear 43 is assembled with the output shaft of the servo motor; the output shaft of the servo motor drives the drive gear 43 to move clockwise / counterclockwise in a periodic motion, and drives the turntable part 41 to rotate circumferentially in the opposite / positive direction, with a single rotation angle not exceeding 180 degrees per cycle;

[0044] The turntable 41 is integrally injection molded from a gear disk 411, a pusher disk 412 located inside it, and a connecting shaft that passes through the positioning bracket 44. The gear disk 411 meshes with the drive gear 43. The pusher disk 412 extends outward from its circumference and contacts the first retracting wheel 24 when it rotates to its highest point. The length of the contact is positively correlated with the horizontal displacement of the first retracting wheel 24. Through the alternating action of multiple pusher disks 412 and their cooperation with the elastic telescopic member 23, the horizontal oscillating screening action of the first screening plate 21 is realized.

[0045] The swinging part 42 includes a swing arm 421, one end of which is connected to the side wall edge of the gear disk 411 away from the push disk 412 via a rotating shaft, and the other end is rotatably connected to the guide wheel 422; the sliding end of the guide wheel 422 is nested in the guide groove of the track 423; when the gear disk 411 rotates periodically in both directions, the swing arm 421 swings up and down in a wave shape due to geometric constraints, and drives the second screening plate 31 to complete the vertical oscillating screening action by intermittently pushing the second retracting wheel 34 in coordination with gravity;

[0046] In this embodiment, it should be specifically noted that the elastic telescopic member 23 includes a tube body 231, one end of which is fixed to the side plate of the first rotating bracket 22, and the other end extends axially toward the first screening plate 21; a piston rod 232 is movably inserted into the tube body 231, one end of which is installed on the first retraction wheel 24, and the other end is movably nested inside the tube body 231, and this end is connected to the end wall of the tube body 231 by a spring 233; the elastic telescopic member 23 can also be replaced by other equivalent elastic telescopic components;

[0047] The pore size on the surface of the first screening plate 21 is larger than the pore size on the surface of the second screening plate 31, forming a gradually decreasing pore size gradient, thereby realizing multi-level screening function.

[0048] The angle adjustment mechanism 6 includes a lifting arm 61 located inside the cavity of the housing 1. Its bottom end is connected to a lever arm 62 via a hinge point, and the other end of the lever arm 62 is hinged to the first screening plate 21. A horizontally extendable sleeve 64 is fixed to the side of the lifting arm 61 near the inner wall of the housing 1, and the top end is connected to a baffle 63 for opening and closing the bottom opening of the receiving funnel 13. The sleeve 64 is poweredly connected to a telescopic cylinder on the outer wall of the housing 1. The telescopic shaft drives the sleeve 64 to lift the angle adjustment mechanism 6 as a whole. At the same time, the sleeve 64 can absorb the horizontal oscillation force transmitted from the first screening plate 21 to the lifting arm 61 and the lever arm 62, eliminating the motion interference with the telescopic cylinder. The lifting arm 61 lifts the end of the upper screening mechanism 2 through the lever action of the lever arm 62. When the baffle 63 approaches the receiving funnel 13, the first retraction wheel 24 disengages from the movement trajectory of the pusher plate 412. Under the elastic force of the elastic telescopic member 23, the sleeve 64 is horizontally reset, so that the baffle 63 is precisely aligned with the receiving funnel 13 to achieve blockage discharge control.

[0049] To further accelerate the spreading speed of the material after being discharged from the receiving funnel 13 to the first screening plate 21, the structure of the first screening plate 21 is further optimized. Specifically, a spreading mechanism 5 is installed on the first screening plate 21. The spreading mechanism 5 includes a scraper 53 that can slide axially along the partition strip 211 on the inner wall of the first screening plate 21. A connecting rod 52 is connected above the scraper 53. The other end of the connecting rod 52 extends outward parallel to the scraper 53. After bending and rotating downward above the turntable 41, it connects to the drive arm 51. The drive arm 51 meshes with the gear disk 411. The drive arm 51 is slidably engaged with the limiting groove 112 preset on the inner wall of the main box 11.

[0050] In order to enable the spreading mechanism 5 to adaptively adjust to the angle deflection of the upper screening mechanism 2 while maintaining the transmission relationship with the composite drive mechanism 4, the structure of the spreading mechanism 5 needs to be optimized: Specifically, a notch is opened at the top of the scraper 53 and it forms a rotatable connection with one end of the connecting rod 52. The other end of the connecting rod 52 adopts a telescopic structure design, and its bottom end is slidably engaged in the pre-set relief groove 511 at the top of the drive arm 51. When the upper screening mechanism 2 deflects, the scraper 53 will slide along the axial direction of the first screening plate 21 and drive the connecting rod 52 to extend and retract. At this time, the telescopic end of the connecting rod 52 will slide adaptively along the relief groove 511, thereby ensuring the stability of the overall structure of the spreading mechanism 5 and not interfering with the normal deflection action of the upper screening mechanism 2.

[0051] Working principle of this invention:

[0052] This device has two working modes: dynamic screening mode and diversion and unloading mode;

[0053] When the device is in dynamic screening mode, such as Figures 2 to 10 In the indicated state, the angle adjustment mechanism 6 moves down to the lowest point, receiving the material from the open funnel 13, and lowers one end of the upper screening mechanism 2 connected to it via the lever arm 62; the upper screening mechanism 2 and the lower screening mechanism 3 are driven to rotate towards each other around their respective connected shaft seats 111 until they are parallel to the horizontal line; at this time, the first retraction wheel 24 and the second retraction wheel 34 fall on the movement trajectory of the push plate 412 and the swing arm 421 respectively, preparing for the oscillation action of the compound drive mechanism 4 during operation; at the same time, when the upper screening mechanism 2 deflects towards the horizontal line, the scraper 53 can slide along the axial direction of the first screening plate 21 and pull the connecting rod 52 rotatably connected to it to retract, and the extension end of the connecting rod 52 adaptively retracts along the relief groove 511, so that the spreading mechanism 5 can adapt and adjust with the angle deflection of the upper screening mechanism 2, maintaining its transmission relationship with the compound drive mechanism 4;

[0054] The output shaft of the servo motor drives the drive gear 43 to rotate clockwise / counterclockwise in a periodic motion, driving the turntable 41 to rotate circumferentially in the opposite / positive direction. The single rotation angle per cycle does not exceed 180 degrees. Figures 11 to 12As shown in the diagram; taking the reverse rotation of the turntable 41 as an example, when the contact of the outer edge of the pusher plate 412 contacts the first retractor wheel 24, it pushes the first retractor wheel 24, causing the first screening plate 21 to move to the left relative to the first rotating support 22 and stretch the elastic telescopic member 23. When the pusher plate 412 disengages from the first retractor wheel 24, the first screening plate 21 resets under the elastic force of the elastic telescopic member 23. Through the alternating action of multiple pusher plates 412 and the cooperation of the elastic telescopic member 23, the horizontal oscillation screening action of the first screening plate 21 is achieved. At the same time, when one end of the swing arm 421 is raised to the highest point by rotating 180 degrees in the opposite direction with the gear plate 411, the other end pulls the guide wheel 422 to slide adaptively along the track 423, so that the swing arm 42 1. The swing arm 421 swings vertically and continuously up and down in a wave-like pattern as the gear disk 411 rotates periodically in the opposite / forward direction to push the second retracting wheel 34, driving the second screening plate 31 to slide up along the second rotating bracket 32 ​​via the guide rod 33. When the swing arm 421 gradually removes its force on the second retracting wheel 34, the second screening plate 31 returns to its original position under the action of gravity, completing the vertical oscillation screening action of the second screening plate 31. At the same time, the drive arm 51 rotates bidirectionally and periodically with the gear disk 411, which can drive the scraper 53 at the bottom of the receiving funnel 13 to swing back and forth in the corresponding area of ​​the first screening plate 21, pushing the material at the drop point to spread out quickly, promoting diffusion and increasing the screening rate.

[0055] When the device is in the shunt unloading mode, such as Figures 13 to 14 In the indicated state, the angle adjustment mechanism 6 moves up to the highest point and blocks the receiving funnel 13 to stop feeding. The lever arm 62 lifts one end of the upper screening mechanism 2 connected to it, driving the upper screening mechanism 2 and the lower screening mechanism 3 to rotate in opposite directions around the shaft seat 111 to form a V shape. This causes the first retraction wheel 24 to disengage from the movement trajectory of the pusher plate 412 and the second retraction wheel 34 to be supported on the swing arm 421. At the same time, the scraper 53 slides along the axial direction of the first screening plate 21 and pulls the connecting rod 52 to extend. The extension end of the connecting rod 52 is offset along the relief groove 511 to avoid motion interference and maintain the ability of the scraper 53 to slide along the axial direction of the first screening plate 21.

[0056] When the first screening plate 21 and the second screening plate 31 form a V-shape, their discharge ports tilt downwards and point to both sides respectively. As the gear disk 411 rotates periodically in the opposite / forward direction, the swing arm 421 continuously swings up and down in a wave-like manner, intermittently pushing the second retraction wheel 34 to realize the oscillating discharge action of the second screening plate 31, accelerating the discharge of its unscreened particles into the predetermined storage position. At the same time, the drive arm 51 rotates periodically in both directions with the gear disk 411, driving the scraper 53 to swing back and forth in the corresponding area of ​​the first screening plate 21, completing the cleaning and pushing action of the first screening plate 21, and assisting the discharge of its raised end unscreened particles into the predetermined storage position.

[0057] The above is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, in accordance with the technical plan and its improved concept, should be included under the protection of the present invention.
