Description

Technical Field

[0001] The present invention relates to the technical field of mechanical engineering, and in particular to a material sorting device. Background Art

[0002] In industrial automation production, material sorting devices are key equipment for efficient material sorting, arrangement, and transportation. Traditional material sorting devices usually use vibrating plates, mechanical grippers, or simple rotating structures, but they have the following problems:

[0003] Currently, vibrating discs use high-frequency vibrations to move materials along a spiral track. However, the vibration frequency and track design must strictly match the material characteristics, otherwise it can easily lead to material blockage or jamming (for example, the pipe loading device mentioned in patent CN209701734U is only semi-automated and still requires manual intervention). If traditional discs do not incorporate multi-stage screening functions, processing efficiency can be reduced when materials accumulate or slide unevenly.

[0004] At the same time, existing technologies often use multi-stage material distribution mechanisms, resulting in bulky equipment and high energy consumption (for example, the pipe feeding device in patent CN209701734U requires multiple servo motors and detection sensors to work together). Traditional devices are not adaptable to material size and shape (for example, patent CN209701734U is only compatible with round tubes; square or oval tubes require the replacement of core components). Existing technologies make it difficult to adjust material handling parameters in real time based on material characteristics (for example, the air pressure and elevation angle in Yixin's automation solution require manual adjustment, which cannot meet the needs of continuous production). Summary of the Invention

[0005] The main purpose of the present invention is to provide a material sorting device that aims to solve the current problem of vibrating disc material sorting using high-frequency vibration to move the material along a spiral track. However, the vibration frequency and track design must strictly match the material characteristics, otherwise it is easy to cause material blockage or jamming. If the traditional material sorting turntable does not combine multi-stage screening functions, the processing efficiency is likely to decrease when the material accumulates or slides unevenly. The existing technology often uses a multi-stage material separation mechanism, which results in large equipment size and high energy consumption. The technical problem that traditional devices are insufficiently adaptable to material size and shape.

[0006] In order to achieve the above-mentioned object of the invention, the first aspect of the present invention provides a material sorting device, comprising:

[0018] The hanging member is connected with the horizontal sliding member by bolts through a second adjustment hole opened on the end surface, and the oblique stopper is fixed to the bottom of the hanging member.

[0019] Furthermore, the side push baffle is fixed by a mounting assembly, and the mounting assembly includes a first mounting member and two third adjustment holes;

[0026] Furthermore, the oblique stopper constitutes a screening mechanism, and the height is continuously adjustable in the range of 0-30 mm, which is used for Z-direction height-limited screening;

[0027] The side-pushing straight plates constitute a two-screen mechanism, and the two-screen mechanism is radially adjustable to retain the material with the minimum radial size;

[0048] Reference Figure 1-Figure 7 One embodiment of the present invention provides a material sorting device, comprising:

[0049] The turntable support structure includes a cross roller bearing 21 and a material handling turntable 2. The inner ring of the cross roller bearing 21 is mounted on the main shaft in the middle of the material handling turntable 2. The material handling turntable 2 rotates relative to the main shaft and is driven to rotate around the main shaft by a belt transmission mechanism.

[0050] The circumferential separation structure includes an oblique stopper 3 and two parallel side push baffles 4. The oblique stopper 3 is set at the edge area of ​​the material sorting turntable 2 to guide the production materials to slide from the radial minimum size track to the maximum size track. The side push baffles 4 are arranged in parallel above the material sorting turntable 2. The radial position difference creates a linear speed difference between the production materials to achieve circumferential gap separation.

[0051] The discrete material orderly track changing device includes a guide plate 22 and / or a compressed air nozzle 23 arranged on the edge of the material sorting turntable 2, which is used to arrange the production materials that slide to the maximum size track at equal intervals in the circumferential direction.

[0052] In this embodiment, the material sorting device includes the following structures:

[0053] Turntable Support Structure: The material handling turntable 2 is mounted on the rotating spindle via a cross-roller bearing 21. The cross-roller bearing 21 is preferably secured with a spacer to ensure rotational accuracy. The belt drive mechanism consists of a synchronous pulley assembly and a polyurethane timing belt 15. The driving pulley 13 is connected to the output shaft of the drive motor 12, and the driven pulley 14 is fixedly connected to the outer flange of the cross-roller bearing 21, thereby driving the material handling turntable 2 rotating on the spindle.

[0054] Circumferential separation structure: the oblique block 3 is installed on the edge area of the sorting turntable 2 through the adjustable suspension assembly fixing part 5, the horizontal sliding part 6 and the suspension part 8, and is used for guiding the material to slide along the radial direction from the smallest size track to the largest size track. The two parallel arranged side push blocking plates 4 are fixed on the top of the turntable circumferential blocking plate 17 through the installation assembly first mounting part 10 and the third adjusting hole 11, and a linear velocity difference is generated through the radial position difference, so that the gap separation of the material in the circumferential direction is realized.

[0055] Discrete material ordered track changing device: the guide plate 22 or the compressed air nozzle 23 is arranged on the edge of the sorting turntable 2, and is used for arranging the material slid to the largest size track in the circumferential direction at equal intervals. The injection direction of the compressed air nozzle 23 is at an angle of 15°-30° with the tangent direction of the turntable, and the air pressure is adjustable in the range of 0.2-0.8 MPa.

[0056] Among them, the high-precision rotation performance of the cross roller bearing 21 combines with the belt transmission mechanism, ensures the smooth operation of the sorting turntable 2, reduces the vibration and wear, and prolongs the service life of the equipment. The oblique block 3 and the side push blocking plate 4 realize multi-stage separation of the material in the radial and circumferential directions through the adjustable installation assembly, and improve the separation efficiency and precision. The guide plate 22 or the compressed air nozzle 23 precisely controls the material spacing through controllable air pressure and angle, and adapts to the arrangement requirements of different size materials.

[0057] Further, the belt transmission mechanism includes a synchronous belt wheel set and a polyurethane synchronous belt 15, a driving wheel 13 of the synchronous belt wheel set is connected with an output shaft of a driving motor 12, a driven wheel 14 is fixedly connected with an outer ring flange of the cross roller bearing 21, and the outer ring flange of the cross roller bearing 21 is fixedly connected with the bottom of the sorting turntable 2, and the polyurethane synchronous belt 15 is installed on the driving wheel 13 and the driven wheel 14 for transmission.

[0059] It should be noted that the driving motor 12 is fixedly installed on the base 1 through a leg, the driving wheel 13 is connected with the output shaft of the driving motor 12 through a key, and the driven wheel 14 is fixedly connected with the outer ring flange of the cross roller bearing 21 through a bolt. The polyurethane synchronous belt 15 is installed between the driving wheel 13 and the driven wheel 14, and a tooth-shaped structure is arranged on the surface and matches the wheel groove for transmission. The flexibility and wear resistance of the polyurethane synchronous belt 15 ensure smooth transmission and reduce noise.

[0060] In some embodiments, the base 1 is rotatably connected with a tensioning wheel 16 through a rotating shaft, and the tensioning wheel 16 abuts one side of the polyurethane synchronous belt 15 to ensure the tightness of the polyurethane synchronous belt 15.

[0061] It should be noted that the base 1 is rotatably connected to a tensioning pulley 16 via a rotating shaft. The tensioning pulley 16 abuts one side of the polyurethane timing belt 15 and maintains the tightness of the polyurethane timing belt 15 by adjusting the position of the rotating shaft. The tensioning pulley 16 dynamically adjusts the tension of the polyurethane timing belt 15 to prevent slippage or breakage, ensuring long-term transmission efficiency.

[0062] In some embodiments, the spraying direction of the compressed air nozzle 23 is at an elevation angle of 15°-30° with respect to the tangential direction of the material handling turntable 2 , and the outlet pressure of the compressed air nozzle 23 is adjustable in the range of 0.2-0.8 MPa.

[0063] It should be noted that the compressed air nozzle 23 is directed at an elevation angle of 15°-30° relative to the tangent of the material handling turntable 2, and the nozzle outlet pressure is controlled by a pressure regulating valve within the range of 0.2-0.8 MPa. The adjustable pressure and inclination design allows for precise control of material spacing, adapting to the fluidity requirements of different materials and reducing the risk of clogging.

[0064] In some embodiments, a full material gate 20 is provided downstream of the three-screen mechanism composed of two parallel side push baffles 4, which is driven by compressed air and is used for dynamic opening and closing of the discharge port.

[0065] It should be noted that the full-load gate 20 is powered by compressed air and installed at the discharge port downstream of the three-screen mechanism. The gate is actuated by a pneumatic cylinder and opens and closes dynamically based on the material accumulation state. When the material load approaches full, the gate automatically closes to prevent overflow; when the material level decreases, the gate opens to resume discharge. The gate's opening and closing logic is controlled by a sensor installed on the edge of the turntable to monitor the material level in real time.

[0066] In some embodiments, the oblique stopper 3 is mounted via an adjustable suspension assembly, which includes a fixing member 5, a horizontal sliding member 6, and a suspension member 8;

[0067] The fixing member 5 is fixedly connected to the top of the turntable circumferential baffle 17 by bolts;

[0068] The horizontal sliding member 6 is embedded in the sliding groove of the fixing member 5, and a first adjustment hole 7 is opened on the top of the horizontal sliding member 6. The horizontal sliding member 6 is fixed to the fixing member 5 by bolts through the first adjustment hole 7, and the first adjustment hole 7 is used to adjust the horizontal position;

[0069] The hanging member 8 is bolted to the horizontal sliding member 6 via a second adjustment hole 9 opened on the end surface, and the oblique stopper 3 is fixed to the bottom of the hanging member 8 .

The horizontal slide 6 is embedded in the slide groove of the fixed member 5 and bolted to the fixed member 5 via a first adjustment hole 7, enabling horizontal position adjustment. The suspension member 8 is connected to the horizontal slide 6 via a second adjustment hole 9, and the diagonal block 3 is fixed to the bottom of the suspension member 8. Through the multi-level adjustment of the first adjustment hole 7 and the second adjustment hole 9, the height and tilt angle of the diagonal block 3 can be flexibly adapted to the sorting requirements of different materials, improving the versatility of the equipment.

[0071] In some embodiments, the side push baffle 4 is fixed by a mounting assembly, and the mounting assembly includes a first mounting member 10 and two third adjustment holes 11;

[0072] The first mounting member 10 is fixed to the top of the turntable circumferential baffle 17 by bolts;

[0073] The two third adjustment holes 11 are opened on the first mounting member 10 , and the side push baffle 4 is radially adjustable in the third adjustment holes 11 by means of bolts.

[0074] It should be noted that the side push baffle 4 is secured via a first mounting member 10 and two third adjustment holes 11. The first mounting member 10 is bolted to the top of the turntable's circumferential retaining plate 17. The side push baffle 4 is radially adjustable within the third adjustment holes 11 via bolts. The radial adjustment function of the third adjustment holes 11 allows the side push baffle 4 to adapt to different material sizes, optimizing material separation.

[0075] In some embodiments, the turntable circumferential stop 17 is provided on the outer edge of the material handling turntable 2, and the surface roughness of the turntable circumferential stop 17 is ≤ Ra1.6, and is used to constrain the material sliding trajectory and provide a mounting base for the circumferential separation structure;

[0076] The surface of the material handling turntable 2 is provided with an anti-collision coating, the diameter of the disk is 200-1000mm, and the total runout accuracy is ≤0.1mm.

[0077] It should be noted that the surface roughness of the turntable's circumferential stop 17 is ≤ Ra1.6, achieved through electrospark machining or polishing, and coated with an anti-collision coating such as polytetrafluoroethylene. The diameter of the material handling turntable 2 ranges from 200-1000mm, with a total runout accuracy of ≤0.1mm. This low-roughness surface and anti-collision coating reduce frictional losses during material slippage, while the total runout accuracy ensures stable turntable operation.

[0078] In some embodiments, a second mounting member 18 is mounted on the top of the turntable circumferential stop 17 via bolts, and a side push straight plate 19 is mounted on the second mounting member 18 via bolts;

The mounting plate is fixed to the second mounting member 18 by bolts, and the strip plate is mounted on one side of the mounting plate by bolts, and a T-shaped pressing member is provided on the strip plate by bolts.

[0080] It should be noted that the side-pushing straight plate 19 is fixed to the top of the turntable's circumferential baffle 17 via a second mounting member 18. The side-pushing straight plate 19 comprises a mounting plate, a strip plate, and a T-shaped pressure piece, all secured in place by bolts. The T-shaped pressure piece enhances the structural strength of the side-pushing straight plate 19, adapting to high-frequency material pushing and preventing deformation.

[0081] In some embodiments, the oblique stopper 3 constitutes a screening mechanism, and the height is continuously adjustable in the range of 0-30 mm, and is used for Z-direction height-limited screening;

[0082] The side-pushing straight plate 19 constitutes a two-screen mechanism, and the two-screen mechanism is radially adjustable to retain the material with the minimum radial size;

[0083] The two parallel side push baffles 4 constitute a three-screen mechanism for removing NG materials.

[0084] It should be noted that the oblique stopper 3 of the first screening mechanism has a continuously adjustable height range of 0-30 mm, and retains materials of a specific size through Z-axis height limit screening.

[0085] The side push straight plate 19 of the second screening mechanism is radially adjustable and realizes preliminary sorting by retaining the material with the minimum radial size.

[0086] The side push baffle 4 of the three-screen mechanism is set in parallel to remove NG materials through the difference in linear speed.

[0087] The three screening mechanisms work together in layers to achieve efficient sorting and rejection of materials, improving final product quality and production efficiency.

[0088] Description: The material sorting disc 2 is installed on the base 1 and fixedly connected with the synchronous pulley set of the driving motor 12 through the flanges of the inner and outer rings of the cross roller bearing 21, ensuring the stability of the rotation of the material sorting disc 2. Then, the tension of the polyurethane synchronous belt 15 in the belt transmission mechanism is adjusted, and the side of the polyurethane synchronous belt 15 is abutted by the tensioning wheel 16 to ensure the transmission efficiency. Subsequently, the inclination angle and height of the inclined blocking piece 3 are adjusted according to the characteristics of the material, and the horizontal sliding piece 6 and the suspension piece 8 of the adjustable suspension assembly are bolted to make the material gradually slide along the radial track to the maximum size area. At the same time, the radial position of the parallel side blocking plate 4 is set, the linear velocity difference is used to realize the circumferential direction gap separation of the material, and the auxiliary material equidistance arrangement is realized by adjusting the elevation angle and air pressure of the compressed air nozzle 23. After the driving motor 12 is started, the material rotates with the material sorting disc 2, the inclined blocking piece 3 guides the material to slide, the side blocking plate 4 completes the preliminary separation, the full gate 20 opens and closes the discharge port according to the sensor signal to prevent overflow. The surface roughness of the disc circumferential wall 17 needs to be monitored during operation to reduce friction loss, and the integrity of the anti-collision coating needs to be checked regularly. When the material is close to full load, the full gate 20 is automatically closed, and after the material is reduced, it is reopened to form a continuous material sorting cycle. After the operation is completed, the driving motor 12 is turned off and the power is cut off, and the guide plate 22, the compressed air nozzle 23 and other components are disassembled for cleaning to ensure that there is no residual material affecting the next use. If different size materials need to be replaced, the radial position of the side blocking plate 4 needs to be adjusted through the third adjusting hole 11, or the height of the inclined blocking piece 3 needs to be fine adjusted through the second adjusting hole 9 of the suspension piece 8 to adapt to the screening requirements of the new material.
