Description

Technical Field

[0001] This invention relates to the field of material feeding technology, and in particular to a centripetal eccentric feeder for centripetal and eccentric transport of spherical materials. Background Technology

[0002] Currently, traditional feeding methods have many limitations. Manual feeding is inefficient, labor-intensive, and the accuracy and stability of manual operation are difficult to guarantee, easily leading to problems such as inaccurate and uneven feeding, affecting the quality and efficiency of subsequent production processes. Ordinary vibratory feeders work well for regularly shaped materials, but for spherical materials, due to their special shape, they are prone to accumulation and jamming in the vibratory feeder, resulting in uneven feeding and difficulty in achieving precise positioning and orientation, failing to meet the needs of some production scenarios with high feeding accuracy requirements. As for other centripetal feeding devices, some devices have complex structures, large size, and high cost. When handling spherical materials, the rolling characteristics of the material may cause problems such as unstable feeding and difficulty in controlling the feeding speed, and maintenance is also relatively cumbersome. Summary of the Invention

[0003] To address the aforementioned problems, the purpose of this invention is to provide a centripetal and eccentric feeder for spherical materials, which enables spherical materials to be transported more directly and efficiently, reducing resistance and jamming risks during movement, while also facilitating machine balance and overall layout optimization.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a spherical material centripetal eccentric feeder, comprising: a dial module, including an outlet bearing, a vertical support, an ascending guide rail, a third-stage guide rail, a cover plate, a second-stage guide rail, a guide rail connector, a first-stage guide rail, a T-slot bearing, a bearing pad, and a base plate; the first-stage and second-stage guide rails are fixed to the base plate along a spiral path; the ascending guide rail is positioned eccentrically on the base plate, its upper end is fixedly connected to the third-stage guide rail, and its lower end is fixedly connected to the guide rail connector. The connector is simultaneously fixedly connected to the ascending guide rail, vertical support, and base plate; the outer circumference of the three-stage guide rail is fixedly connected to the top of the vertical support, and a bearing seat is provided at the upper end of the three-stage guide rail to mate with the outlet bearing; the cover plate and the base plate are fixedly connected by bearing pads, and T-slot bearings are connected to both ends of the bearing pads through shaft holes; the gear module is rotatably mounted on the dial module, including an upper dial ring, guide gears, a gear ring, a gear ring, a lower dial ring, and supporting aluminum pillars; the gear ring and the lower dial ring are circumferentially connected by multiple supports. The aluminum support column is fixedly connected, and the upper surface of the toothed ring is fixedly connected to the toothed ring and the front end of the guide tooth by bolts. The guide tooth is located on the inner side above the toothed ring. The upper deflector ring is set on the top of the toothed ring and fixedly connected to the rear end of the guide tooth. The T-groove bearings located at both ends of the bearing pad column contact the upper deflector ring and the lower deflector ring respectively, so that the toothed module and the deflector plate module rotate relative to each other. The rotation provides a deflecting force for the spherical material, so that the material moves and is conveyed along the primary guide rail, the secondary guide rail and the rising guide rail. The drive module includes a direct drive motor, a motor mounting plate and a clamping mechanism. The system consists of an aluminum component, a D-hole flange, an aluminum column, and a drive gear. The drive gear meshes with the gear ring for transmission. The drive module is located in a recess on the upper surface of the cover plate. The upper end of the aluminum column is connected to the motor mounting plate, and the lower end is fixedly connected to the cover plate. The direct-drive motor is fixed above the motor mounting plate. The motor output shaft is pressed against the clamping aluminum component and the D-hole flange. The D-hole flange is fixedly connected to the drive gear, allowing the D-hole flange and the drive gear to rotate synchronously with the motor output shaft, thereby driving the gear ring to rotate. The gear ring drives the entire gear shifting module to rotate relative to the shifting disc module.

[0005] In some embodiments, the inner circumferential surface of the toothed ring is provided with an arc-shaped groove for accommodating a single spherical material, and a guide tooth is provided between adjacent arc-shaped grooves, with each arc-shaped groove accommodating only one spherical material.

[0006] In some embodiments, the first end of the primary guide rail is connected to the last end of the secondary guide rail, the secondary guide rail surrounds the outside of the rising guide rail, and the upper end of the secondary guide rail is connected to the cover plate and the tertiary guide rail.

[0009] In some embodiments, the left side of the cover plate is a notch portion, and the outer right end is provided with a notch for installing the drive module; the notch portion of the cover plate allows the spherical material to enter the arc-shaped groove between the two guide teeth downwards, at which time the bottom of the spherical material contacts the bottom plate. A bearing fixing component is fixedly installed on the upper surface of the cover plate, and a third miniature bearing for preventing material blockage is installed on the bearing fixing component; the third miniature bearing, together with the toothed ring and the base plate, forms an enclosing structure, which serves as the inlet for spherical materials; this inlet is correspondingly set to the inlet of the primary guide rail.

[0010] In some embodiments, the three-stage guide rail and the outlet bearing are positioned eccentrically on the cover plate.

[0011] In some embodiments, a first micro-bearing is installed at the bottom of the arcuate groove of the toothed ring, and the outer ring of the first micro-bearing is used to abut against the upper part of the spherical material to apply downward and forward forces to the spherical material.

[0012] In some embodiments, the height of the toothed ring is higher than the height of the primary guide rail.

[0013] In some embodiments, multiple second micro-bearings are respectively provided at the upper end of the primary guide rail, between the two ascending guide rails, and at the tertiary guide rail, and the rolling direction of the second micro-bearings is the same as the movement direction of the spherical material.

[0014] The present invention has the following advantages due to the adoption of the above technical solutions: 1. The present invention uses a toothed conveyor to enable materials to move quickly from the material source to the outlet under the drive of the toothed conveyor.

[0015] 2. The present invention has a stable structure, small size, light weight, compact structure, close cooperation between components, low vibration and noise during operation, and can operate stably for a long time.

[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0021] In one embodiment of the present invention, a centripetal eccentric feeder for spherical materials is provided. In this embodiment, as... Figures 1 to 7 As shown, the feeder includes: The dial module 1 includes an outlet bearing 1-1, a vertical support 1-2, a rising guide rail 1-3, a three-stage guide rail 1-4, a bearing connector 1-5, a cover plate 1-6, a two-stage guide rail 1-7, a guide rail connector 1-8, a first-stage guide rail 1-9, a T-slot bearing 1-10, a bearing pad 1-11, and a base plate 1-12. The first-stage guide rail 1-9 and the second-stage guide rail 1-7 are fixed to the base plate 1-12 along a spiral path. The rising guide rail 1-3 is positioned eccentrically on the base plate 1-12 to reduce its space requirement. The upper end of the rising guide rail 1-3 is fixedly connected to the three-stage guide rail 1-4, and the lower end of the rising guide rail 1-3 is fixedly connected to the guide rail connector 1-8. The guide rail connector 1-8 is simultaneously connected to the rising guide rail 1-3 and the vertical support 1-4. Support member 1-2 and base plate 1-12 are fixedly connected. The bottom of guide rail connector 1-8 is fixed on base plate 1-12. The inner side of guide rail connector 1-8 is fixedly connected to rising guide rail 1-3. The outer side of guide rail connector 1-8 is fixedly connected to vertical support member 1-2, thereby stabilizing the structure. The outer circumference of three-stage guide rail 1-4 is fixedly connected to the top of vertical support member 1-2. The upper end of three-stage guide rail 1-4 is provided with a bearing seat to cooperate with the outlet bearing 1-1. Cover plate 1-6 and base plate 1-12 are fixedly connected by bearing pad 1-11. T-slot bearings 1-10 are respectively connected to the bearing pad 1-11 between cover plate 1-6 and base plate 1-12 through shaft holes.

[0022] The toothed module 2 is rotatably mounted on the dial module 1 and includes an upper dial ring 2-1, guide teeth 2-2, a toothed ring 2-3, a toothed ring 2-4, a lower dial ring 2-5, and supporting aluminum pillars 2-6. The toothed ring 2-4 and the lower dial ring 2-5 are circumferentially fixedly connected by multiple supporting aluminum pillars 2-6. The upper surface of the toothed ring 2-4 is fixedly connected to the front end of the toothed ring 2-3 and the guide teeth 2-2 by bolts. The guide teeth 2-2 are located inside the toothed ring 2-3. The upper dial ring 2-1 is located on the top of the toothed ring 2-3. The inner circumferential surface of the toothed ring 2-4 is provided with an arc-shaped groove for accommodating a single spherical material. Guide teeth 2-2 are provided between adjacent arc-shaped grooves. Each arc-shaped groove can only accommodate one spherical material. The T-groove bearings 1-10 located at both ends of the bearing pad 1-11 contact the upper deflector ring 2-1 and the lower deflector ring 2-5 respectively, so that the deflector module 2 and the deflector module 1 rotate relative to each other. The rotation provides a deflecting force to the spherical material, so that the material moves and is conveyed along the primary guide rail 1-9, the secondary guide rail 1-7 and the rising guide rail 1-3. The drive module 3 includes a direct drive motor 3-1, a motor mounting plate 3-2, a clamping aluminum component 3-3, a D-hole flange 3-4, an aluminum column 3-5, and a drive gear 3-6. The drive gear 3-6 meshes with the gear ring 2-3 for transmission. The drive module 3 is located in the recessed position on the upper surface of the cover plate 1-6. The upper end of the aluminum column 3-5 is connected to the motor mounting plate 3-2, and the lower end is fixedly connected to the cover plate 1-6. The direct drive motor 3-1 is fixed above the motor mounting plate 3-2. The motor output shaft is pressed and engaged with the clamping aluminum component 3-3 and the D-hole flange 3-4. The D-hole flange 3-4 is fixedly connected to the drive gear 3-6, so that the D-hole flange 3-4 and the drive gear 3-6 rotate coaxially and synchronously with the motor output shaft, thereby driving the gear ring 2-3 to rotate. The gear ring 2-3 drives the entire gear module 2 to rotate relative to the dial module 1.

[0023] In one possible implementation, such as Figure 6 As shown, the first end of the primary guide rail 1-9 is connected to the tail end of the secondary guide rail 1-7. The secondary guide rail 1-7 surrounds the outside of the rising guide rail 1-3, and most of the area of ​​the rising guide rail 1-3 is surrounded by the secondary guide rail 1-7. The upper end of the secondary guide rail 1-7 is connected to the cover plate 1-6 and the tertiary guide rail 1-4.

[0024] In this embodiment, the length of the primary guide rail 1-9 is greater than the length of the secondary guide rail 1-7, and the radius of curvature of the primary guide rail 1-9 is greater than the radius of curvature of the secondary guide rail 1-7. This is used to change the motion state of the spherical material on the base plate 1-12 into circular motion, push the spherical material towards the rising guide rail 1-3, change it into curved upward motion, and send it to the tertiary guide rail 1-4 and the outlet bearing 1-1.

[0025] In this embodiment, optionally, the inner arc of the primary guide rail 1-9 and the outer arc of the secondary guide rail 1-7 form a primary circular track, and the inner arc of the secondary guide rail 1-7 and the rising guide rail 1-3 form a secondary rising track; the primary circular track and the secondary rising track are independent of each other and have no overlapping parts.

[0026] In this embodiment, optionally, two vertical support members 1-2 are provided on the inner side of the secondary guide rail 1-7. The two vertical support members 1-2 are arranged opposite to each other on the outer side of the two rising guide rails 1-3 and the inner side of the secondary guide rail 1-7. The vertical support members 1-2 and the rising guide rails 1-3 are fixed to the base plate 1-12 through the guide rail connector 1-8. The base plate 1-12 and the cover plate 1-6 are connected by a T-slot bearing and a pad.

[0027] In one possible implementation, such as Figures 1 to 3As shown, the left side of the cover plate 1-6 is a notch, and the outer right end is provided with a notch for installing the drive module 3. The notch of the cover plate 1-6 allows spherical materials to enter downward into the arc-shaped groove between the two guide teeth 2-2, at which time the bottom of the spherical material contacts the base plate 1-12; the notch can simultaneously introduce multiple spherical materials, which are simultaneously accommodated in the arc-shaped groove; the remaining spherical materials that have not entered the arc-shaped groove will be in a waiting state at the notch above the cover plate 1-6, and will be stacked upwards layer by layer above the materials that have already entered.

[0028] A bearing fixing component 1-5 is fixedly installed on the upper surface of the cover plate 1-6. A third micro bearing for preventing material blockage is installed on the bearing fixing component 1-5. The third micro bearing, together with the toothed ring 2-4 and the base plate 1-12, forms an enclosing structure, which serves as the inlet for spherical materials. This inlet corresponds to the inlet of the primary guide rail 1-9.

[0029] In use, driven by the drive module 3, the tooth module 2 rotates counterclockwise, which in turn pushes the spherical material in the arc-shaped groove to move along the direction of the guide tooth 2-2, reaching below the bearing fixing part 1-5 and continuing to move towards the first-level guide rail 1-9. At this time, the spherical material enters the entrance formed by the third micro bearing, the tooth ring 2-4, and the base plate 1-12 and enters the first-level guide rail 1-9. The first-level guide rail 1-9 changes the linear motion of the spherical material on the base plate 1-12 to circular motion. After being guided by the first-level guide rail 1-9, the spherical material is guided by the second-level guide rail 1-7 to the rising guide rail 1-3. The rising guide rail 1-3 changes the spherical material from a near-circular motion to a curved upward motion and conveys it to the third-level guide rail 1-4. Finally, the spherical material is output upward to the outside through the outlet bearing 1-1.

[0030] In one possible implementation, the three-stage guide rail 1-4 and the outlet bearing 1-1 are positioned eccentrically on the cover plate 1-6.

[0031] In this embodiment, to ensure the overall volume of the feeder, the outlet bearing 1-1 is positioned 6.5cm off-center, with the ratio of the offset position to the overall size of the feeder being approximately 1:34. If the outlet were positioned in the center, the feeder volume would increase by 1.2 times, provided that the material does not get stuck.

[0032] In one possible implementation, a first micro-bearing is installed at the bottom of the arc-shaped grooves of the toothed rings 2-4. The outer ring of the first micro-bearing is used to abut against the upper part of the spherical material to apply downward and forward forces to the spherical material, thereby reducing the possibility of the spherical material jumping up, stacking, and getting stuck during the circumferential motion of the spherical material.

[0033] In one possible implementation, the height of the toothed ring 2-4 is higher than the height of the primary guide rail 1-9, which reduces the possibility of the spherical material jumping up and stacking until it gets stuck during the circular motion of the spherical material.

[0034] In one possible implementation, multiple second micro-bearings are respectively installed at the upper end of the primary guide rail 1-9, between the two ascending guide rails 1-3, and at the tertiary guide rail 1-4. The rolling direction of the second micro-bearings is the same as the movement direction of the spherical material, which is used to reduce the friction force on the spherical material during movement.

[0035] In the above embodiments, as Figure 1 As shown, the toothed module 2 can be installed inside the dial module 1. By rotating the toothed module 2, the spherical material is transported from the inlet to the material outlet.

[0036] In the above embodiments, such as Figure 1 As shown, the direct drive motor 3-1 in the drive module 3 transmits power to the drive gear 3-6 through its output shaft; the drive gear 3-6 then meshes with the gear ring 2-3 as a power output. The tooth ratio of the drive gear 3-6 to the gear ring 2-3 is 22:88 to obtain a larger torque to agitate the spherical material. The direct drive motor 3-1 drives the gear-agitating module 2 to rotate relative to it, completing the agitation and transportation of the spherical material.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
