Description

Technical Field

[0001] This invention relates to the field of ceramic powder feeding device technology, and particularly to an array-type vibrating feeding device. Background Technology

[0002] Ceramic production demands a high degree of precision in powder feeding. Even slight deviations in the feeding amount can lead to uneven density in the subsequent green body forming, or even defects such as cracking and deformation during sintering. However, existing multi-channel feeding devices, due to structural design limitations (limited miniaturization of the output rods of linear actuators such as cylinders or electric push rods), have limited material distribution accuracy in the hopper, and are gradually failing to meet the high precision requirements of powder feeding in precision ceramic production. Summary of the Invention

[0003] The present invention aims to improve at least one technical problem in the prior art.

[0004] This invention provides an array-type vibratory feeding device, comprising: Mounting base; A hopper, which is fixed on the mounting base, has a discharge port at its lower part; A support plate, which is connected to the mounting base; The discharge assembly comprises multiple sets arranged at intervals along the left-right direction. Each discharge assembly includes a first opening / closing driver, a first discharge baffle, a second opening / closing driver, and a second discharge baffle. Both the first and second discharge baffles are mounted on a support plate. The surface of the first discharge baffle away from the hopper has a first clearance groove, and the surface of the second discharge baffle away from the hopper has a second clearance groove. The openings of the first and second clearance grooves face the same direction and are staggered vertically. Both the first and second opening / closing drivers are located on the support plate. The first opening / closing driver includes a first driving rod that abuts against the first discharge baffle and is partially located in the second clearance groove. The second opening / closing driver includes a second driving rod that abuts against the second discharge bottom plate and is partially located in the first clearance groove of the first discharge baffle of the next set of discharge assemblies.

[0005] The beneficial effects of this invention are as follows: By setting up multiple sets of discharge components arranged at intervals along the left and right directions, and in each set of discharge components, the first clearance groove of the first discharge baffle and the second clearance groove of the second discharge baffle are staggered in the vertical direction, the first drive rod is located in the second clearance groove and the second drive rod is located in the first clearance groove of the next set of discharge components, under the premise that the miniaturization of the output rod of linear actuators such as cylinders or electric push rods is limited, the interference between each drive rod and the corresponding discharge baffle is reduced, so that multiple sets of discharge components can be arranged compactly. At the same time, the fineness of hopper discharge is improved by the independent opening and closing control of multiple sets of discharge components.

[0006] As some sub-solutions of the above technical solution, the thickness of the first discharge baffle and / or the second discharge baffle is 1 to 3 mm, and the maximum outer diameter of the first drive rod and / or the second drive rod is 1.5 to 5 mm. By setting the thickness of the first discharge baffle and / or the second discharge baffle to 1 to 3 mm and the maximum outer diameter of the first drive rod and / or the second drive rod to 1.5 to 5 mm, under the premise that the miniaturization of the output rod of linear actuators such as cylinders or electric push rods is limited, the overall space occupied by the discharge assembly is further reduced, making the arrangement of multiple discharge assemblies more reasonable. At the same time, it reduces the inertia when the drive rod drives the discharge baffle, improves the action response speed of the discharge baffle, and thus improves the fine control effect of hopper discharge.

[0007] As a sub-solution of the above technical solution, the discharge assembly includes a first vibrator, which is disposed on the first discharge baffle. By mounting the first vibrator on the first discharge baffle, given the limited miniaturization of the output rod of linear actuators such as cylinders or electric push rods, the vibration of the first vibrator can assist the material in falling from the discharge port, reducing material accumulation at the first discharge baffle, making the material discharge process more uniform, and further improving the precision of hopper discharge.

[0008] As a sub-solution of the above technical solution, the support plate is provided with a mounting plate, and the discharge assembly further includes a first spring arm. The first spring arm is formed by making a cut in the mounting plate, and the first discharge baffle is installed on the first spring arm. By forming the first spring arm by making a cut in the mounting plate and installing the first discharge baffle on the first spring arm, the elastic characteristics of the first spring arm can be adapted to the driving action of the first drive rod, making the fit between the first discharge baffle and the discharge port easier to control, which helps to improve the control accuracy of the discharge amount and optimize the fine discharge effect.

[0009] As some sub-solutions of the above technical solution, the first discharge baffle includes a connecting part and a sealing part. The discharge assembly also includes an ejector screw. The connecting part is connected to the first spring arm. The first spring arm is provided with a first screw hole. The ejector screw is threadedly connected to the first screw hole. The tail of the ejector screw extends away from the discharge port and holds the first discharge baffle. When the first drive rod is in the extended state, the first drive rod presses the sealing part tightly against the bottom side of the discharge port and partially closes the discharge port. The first discharge baffle includes a connecting part and a sealing part. The ejector screw is threadedly connected to the first screw hole of the first spring arm and holds the first discharge baffle. By rotating the ejector screw, the shape of the sealing part can be finely adjusted, so that the sealing part fits the discharge port more closely, further improving the precision of the hopper discharge.

[0010] As a sub-solution of the above technical solution, the connecting part is elastic. The elastic connecting part, together with the first elastic arm, supports the first discharge baffle, allowing the first discharge baffle greater deformation freedom when pressed by the first drive rod, improving the fit with the discharge port and better sealing the discharge port.

[0011] As some sub-solutions of the above technical solution, the first drive rod is located above the second drive rod, and the side of the second drive rod adjacent to the hopper is sloped. The first drive rod being above the second drive rod, and the side of the second drive rod adjacent to the hopper being sloped, allows the first and second discharge baffles to swing at the same angle when the first and second drive rods move with the same fixed retraction amount, simplifying the control design and helping to improve the accuracy of the discharge volume.

[0012] As some sub-solutions of the above technical solution, the support plate is provided with a rotating shaft, the mounting base is provided with a rotating hole, the rotating shaft is rotatably connected to the rotating hole, and the array-type vibrating feeding device further includes a rotary driver, the rotary driver being drive-connected to the rotating shaft. The support plate is rotatably connected to the rotating hole of the mounting base via the rotating shaft, and the rotary driver is drive-connected to the rotating shaft, enabling the rotary driver to drive the support plate to rotate, causing all the first and second discharge baffles to simultaneously leave the discharge port, thus fully opening the discharge port and achieving full-plate discharge.

[0013] As some sub-solutions of the above technical solution, the support plate is rotatably connected to the mounting base, and the array-type vibrating feeding device further includes an angle adjustment component. This angle adjustment component is used to change the installation angle of the support plate and the feeding component, thereby changing the size of the feeding gap between the first and / or second feeding baffles and the feeding port when they are open. By setting the angle adjustment component to change the installation angle of the support plate and the feeding component, and given the limited miniaturization of the output rod of linear actuators such as cylinders or electric push rods, the size of the feeding gap between the first and / or second feeding baffles and the feeding port when they are open can be changed by adjusting the installation angle, thus widening the adjustment range of the feeding volume and allowing the hopper feeding to adapt to different refined feeding standards according to actual needs.

[0014] As a sub-solution of the above technical solution, the angle adjustment assembly includes a first hinge seat, a second hinge seat, a first screw, a second screw, and a first adjusting nut. The first hinge seat is rotatably connected to the support, the first screw is fixedly connected to the first hinge seat, the second hinge seat is rotatably connected to the support plate, and the second screw is fixedly connected to the second hinge seat. The first adjusting nut is located between the first screw and the second screw, and its upper and lower ends are threadedly connected to the first screw and the second screw, respectively. When the first adjusting nut rotates, the first screw and the second screw simultaneously move away from or towards each other. The angle adjustment assembly, including the first hinge seat, the second hinge seat, the first screw, the second screw, and the first adjusting nut, allows for precise micro-adjustment of the support plate installation angle, enabling more accurate control of the discharge gap size and further improving the fineness of the hopper discharge. Furthermore, the adjustment process is stable and reliable, adaptable to long-term use requirements. Attached Figure Description

Detailed Implementation

[0017] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] The following is combined Figures 1 to 5 Embodiments of the present invention will be described.

[0019] This invention relates to the field of feeding device technology, specifically to an array-type vibrating feeding device, which aims to solve the problem that in the prior art, under the premise of limited miniaturization of the output rod of linear actuators such as cylinders or electric push rods, the fineness of the material output from the hopper 2 is insufficient, making it difficult to meet the requirements of high-precision feeding.

[0020] The array-type vibrating feeding device in this embodiment includes a mounting base 1, a hopper 2, a support plate 3, and a discharge assembly. The hopper 2 is fixed on the mounting base 1, and a discharge port is provided below the hopper 2. The support plate 3 is connected to the mounting base 1. There are multiple sets of discharge assemblies, which are arranged at intervals along the left and right direction. Each discharge assembly includes a first opening and closing driver, a first discharge baffle 42, a second opening and closing driver, and a second discharge baffle 44. Both the first discharge baffle 42 and the second discharge baffle 44 are mounted on the support plate 3. The surface of the first discharge baffle 42 away from the hopper 2 is provided with a first clearance groove 421, and the surface of the second discharge baffle 44 away from the hopper 2 is provided with a first clearance groove 421. A second clearance groove 441 is provided. The openings of the first clearance groove 421 and the second clearance groove 441 face the same direction. The first clearance groove 421 and the second clearance groove 441 are staggered in the vertical direction. The first opening and closing driver and the second opening and closing driver are both provided on the support plate 3. The first opening and closing driver includes a first driving rod 411, which abuts against the first discharge baffle 42 and is partially located in the second clearance groove 441. The second opening and closing driver includes a second driving rod 431, which abuts against the second discharge baffle 44 and is partially located in the first clearance groove 421 of the first discharge baffle 42 of the next set of discharge components.

[0021] During operation, the first and second opening / closing actuators of the corresponding discharge components are controlled according to the material feeding requirements. The first opening / closing actuator drives the first driving rod 411 to extend or retract, thereby pushing or releasing the first discharge baffle 42. The second opening / closing actuator drives the second driving rod 431 to extend or retract, thereby pushing or releasing the second discharge baffle 44. The staggered design of the first clearance groove 421 and the second clearance groove 441 allows the first driving rod 411 and the second driving rod 431 to be partially accommodated in the corresponding clearance grooves (including the first clearance groove 421 and the second clearance groove 441) during operation, reducing spatial interference between the driving rods and the discharge baffles (including the first discharge baffle 42 and the second discharge baffle 44). The staggered arrangement of multiple sets of discharge components can realize multi-channel independent material feeding control. Under the premise of limited miniaturization of the linear actuator output rod, the reasonable layout of the material feeding channel is achieved through structural optimization, improving the fineness of material feeding.

[0022] Furthermore, in one embodiment of the present invention, the thickness of the first discharge baffle 42 and the second discharge baffle 44 is 1 to 3 mm, and the maximum outer diameter of the first drive rod 411 and the second drive rod 431 is 1.5 to 5 mm. In the prior art, excessively large dimensions of the discharge baffle and drive rod can easily lead to an increase in the space occupied by the discharge assembly, which is not conducive to the compact arrangement of multiple sets of components. Moreover, larger dimensions will reduce the flexibility of the drive rod's movement and affect the accuracy of material feeding control.

[0023] By limiting the thickness of the first discharge baffle 42 and the second discharge baffle 44, as well as the maximum outer diameter of the first drive rod 411 and the second drive rod 431, to the above-mentioned range, the individual space occupied by the discharge components can be reduced while ensuring structural strength, making the arrangement of multiple discharge components more compact. At the same time, the inertia of the drive rod during extension and retraction is reduced, the response speed of the drive rod is improved, and the opening and closing actions of the first discharge baffle 42 and the second discharge baffle 44 are more precise. Thus, under the premise of limited miniaturization of the linear actuator output rod, the discharge precision of the hopper 2 is further improved.

[0024] Furthermore, in one embodiment of the present invention, the discharge assembly includes a first vibrator 45, which is disposed on a first discharge baffle 42. In the prior art, materials tend to accumulate on the surface of the discharge baffle, resulting in uneven discharge. Especially in precision material feeding scenarios, the accumulation phenomenon will seriously affect the feeding accuracy.

[0025] When the first vibrator 45 is working, it generates vibration and transmits it to the first discharge baffle 42. The vibration can cause the material attached to the surface of the first discharge baffle 42 to fall off and move along the discharge direction, reducing the accumulation of material. During operation, the vibration frequency and amplitude of the first vibrator 45 can be adjusted according to the material characteristics. In conjunction with the opening and closing action of the first discharge baffle 42, the material is discharged from the discharge port evenly and stably. Under the premise that the miniaturization of the linear actuator output rod is limited, the uniformity of the discharge is improved by vibration assistance, and the fine feeding effect is further optimized.

[0026] Furthermore, in one embodiment of the present invention, the support plate 3 is provided with a mounting plate 31, and the discharge assembly further includes a first spring arm 32, which is formed by making a cut in the mounting plate 31, and a first discharge baffle 42 is installed on the first spring arm 32. In the prior art, the discharge baffle is mostly fixed by a rigid connection. When the output rod of the linear actuator is miniaturized and the driving force is limited, the rigid connection is difficult to adapt to the small movements of the drive rod, which easily leads to problems such as the discharge baffle not fitting tightly or moving inflexibly, affecting the discharge accuracy.

[0027] The first spring arm 32 has a certain elastic deformation capability. When the first drive rod 411 extends and retracts to push the first discharge baffle 42, the first spring arm 32 can deform accordingly with the movement of the first discharge baffle 42, adapting to the drive rod (including the first drive rod 411 and the second drive rod 431) to realize the flexible opening and closing of the first discharge baffle 42. Under the premise that the miniaturization of the linear drive output rod is limited, the elastic connection structure improves the action adaptability of the discharge baffle, which helps to improve the material feeding control accuracy.

[0028] Furthermore, in one embodiment of the present invention, the first discharge baffle 42 includes a connecting part 422 and a sealing part 423, and the discharge assembly further includes an ejector screw 47. The connecting part 422 is connected to the first spring arm 32, and the first spring arm 32 is provided with a first screw hole. The ejector screw 47 is threadedly connected to the first screw hole. The tail of the ejector screw 47 extends away from the discharge port and holds the first discharge baffle 42. When the first drive rod 411 is in the extended state, the first drive rod 411 presses the sealing part 423 tightly to the bottom side of the discharge port and partially closes the discharge port.

[0029] The connecting part 422 is used to achieve a stable connection between the first discharge baffle 42 and the first spring arm 32, and the sealing part 423 is used to cooperate with the discharge port to achieve discharge control. During operation, turning the ejector screw 47 can finely adjust the posture of its holding the first discharge baffle 42, thereby finely adjusting the relative position of the sealing part 423 and the discharge port to ensure that the sealing part 423 can fit with the discharge port. When the first drive rod 411 extends, its end pushes against the sealing part 423 and presses it tightly against the bottom side of the discharge port. Combined with the holding action of the ejector screw 47, the sealing part 423 fits tightly with the discharge port, achieving partial closure of the discharge port. The discharge amount can be precisely adjusted by controlling the closure area of ​​the sealing part 423. Under the premise of limited miniaturization of the linear drive output rod, the segmented structure design and the fine adjustment function of the ejector screw 47 improve the accuracy of the discharge port closure and further refine the control range of the discharge amount.

[0030] Furthermore, in one embodiment of the present invention, the connecting portion 422 is elastic. The elasticity of the connecting portion 422, together with the first elastic arm 32, supports the first discharge baffle 42, allowing the first discharge baffle 42 greater deformation freedom when pressed by the first drive rod 411. This improves the fit with the discharge port, better seals the discharge port, reduces fluctuations in discharge volume due to loose connections, and ensures precise material feeding. Specifically, when the first drive rod 411 presses the connecting portion 422, the sealing portion 423 can swing around the fulcrum near the root of the first elastic arm 32, and also around the fulcrum near the root of the connecting portion 422. By rotating the ejector screw 47, the position of the sealing portion 423 can be further optimized to better seal the discharge port of the hopper 2.

[0031] Furthermore, in one embodiment of the present invention, the first drive rod 411 is located above the second drive rod 431, and the side of the second drive rod 431 adjacent to the hopper 2 is inclined. The fact that the first drive rod 411 is above the second drive rod 431, and the side of the second drive rod 431 adjacent to the hopper 2 is inclined, ensures that when the first drive rod 411 and the second drive rod 431 move with the same fixed retraction amount, the swing angles of the first discharge baffle 42 and the second discharge baffle 44 are the same, simplifying the control design and helping to improve the accuracy of the discharge amount.

[0032] Furthermore, in one embodiment of the present invention, the support plate 3 is provided with a rotating shaft 33, and the mounting base 1 is provided with a rotating hole. The rotating shaft 33 is rotatably connected to the rotating hole. The array-type vibrating feeding device also includes a rotary driver, which is drivenly connected to the rotating shaft 33. The support plate 3 is rotatably connected to the rotating hole of the mounting base 1 through the rotating shaft 33, and the rotary driver is drivenly connected to the rotating shaft 33. This allows the rotary driver to drive the support plate 3 to rotate, causing all the first discharge baffles 42 and the second discharge baffles 44 to simultaneously leave the discharge port and fully open the discharge port, achieving full-plate discharge while maintaining the independent and precise control effect of multiple sets of discharge components.

[0033] Furthermore, in one embodiment of the present invention, the support plate 3 is rotatably connected to the mounting base 1, and the array-type vibrating feeding device further includes an angle adjustment component 6. The angle adjustment component 6 is used to change the installation angle of the support plate 3 and the discharge component, so as to change the size of the discharge gap between the first discharge baffle 42 and / or the second discharge baffle 44 and the discharge port when they are open. In the prior art, the size of the gap between the discharge baffle and the discharge port is mostly fixed, which is difficult to adjust according to the material characteristics and the feeding quantity requirements. When the miniaturization of the linear actuator output rod results in a limited baffle travel, the fixed gap cannot meet the requirements of different fine feeding standards.

[0034] Since the first drive rod 411 and the second drive rod 431 in this embodiment keep the outlet closed when they are extended, and the extension length of the first and second drive rods can be stopped by the resistance of the extension through the external control system, in conjunction with the elastic support structure such as the first elastic arm 32 and the elastic connecting part 422, even after the sealing part 423 changes position by rotating through the angle adjustment component 6, the original control logic can still be maintained so that the first drive rod 411 and the second drive rod 431 can close the outlet when they are extended. While miniaturizing the structure, the discharge amount of the outlet is cleverly adjusted, and no complex adaptation adjustment of many parts is required during the adjustment, which effectively simplifies the adjustment of the discharge amount.

[0035] In this embodiment, the angle adjustment component 6 can drive the support plate 3 to rotate around its rotational connection with the mounting base 1, changing the position of the sealing part 423, and thus changing the overall installation angle of the discharge component. When the angle of the support plate 3 changes, the size of the discharge gap formed between the first discharge baffle 42 and / or the second discharge baffle 44 and the discharge port also changes accordingly. The larger the gap, the larger the discharge volume, and the smaller the gap, the finer the discharge volume. During operation, the angle of the support plate 3 is adjusted by the angle adjustment component 6 according to the actual discharge requirements, so that the discharge gap reaches the preset size.

[0036] By coordinating the opening and closing control of the discharge baffle, different precision feeding can be achieved. Under the premise of limited miniaturization of the linear drive output rod, the adjustment range of feeding amount is expanded by angle adjustment, thereby improving the adaptability of the device and the precision of feeding.

[0037] Furthermore, in one embodiment of the present invention, the angle adjustment component 6 includes a first hinge seat 61, a second hinge seat 62, a first screw 63, a second screw, and a first adjusting nut. The first hinge seat 61 is rotatably connected to the mounting base 1, the first screw 63 is fixedly connected to the first hinge seat 61, the second hinge seat 62 is rotatably connected to the support plate 3, the second screw is fixedly connected to the second hinge seat 62, and the first adjusting nut is located between the first screw 63 and the second screw. The upper and lower ends of the first adjusting nut are threadedly connected to the first screw 63 and the second screw, respectively. When the first adjusting nut rotates, the first screw 63 and the second screw simultaneously move away from each other or simultaneously move closer to each other. In the prior art, if the angle adjustment structure is not precise enough, it is easy to cause inaccurate adjustment of the discharge gap. When the miniaturization of the linear actuator output rod leads to higher requirements for material feeding control precision, a coarse adjustment structure is difficult to meet the requirements of fine material feeding.

[0038] The first screw 63 and the second screw have opposite thread directions. When the first adjusting nut is rotated, the first screw 63 and the second screw will move away from each other or move closer to each other axially, thereby pushing the first hinge seat 61 and the second hinge seat 62 to rotate relative to each other, causing the support plate 3 to rotate around its rotational connection with the mounting base 1, thus achieving fine-tuning of the angle. During operation, the angle change of the support plate 3 can be precisely controlled by rotating the first adjusting nut, thereby accurately adjusting the size of the discharge gap. The adjustment process is stable and highly accurate. Under the premise of limited miniaturization of the linear actuator output rod, the precise adjustment structure of the threaded transmission makes the control of the discharge gap more precise, further improving the fineness of the discharge of the hopper 2. Moreover, the structure is simple, the operation is convenient, and it is suitable for long-term use.

[0039] The overall operating principle of the present invention is as follows: During installation, the mounting base 1 is first fixed in a preset position. The connecting part 422 of the first discharge baffle 42 is fixedly connected to the first spring arm 32 by the second screw 48. The ejector screw 47 is turned to adjust the initial position and pre-tightening force of the first discharge baffle 42 so that the relative position of the sealing part 423 and the discharge port is in the best state. By rotating the first adjusting nut, the installation angle of the support plate 3 is adjusted so that the discharge gap between the first discharge baffle 42 and the second discharge baffle 44 and the discharge port reaches the preset size when they are opened. During material feeding, the first and second opening / closing actuators of the corresponding discharge components are controlled according to the required feeding amount and feeding channel: the first opening / closing actuator drives the first driving rod 411 to extend, pressing the sealing part 423 of the first discharge baffle 42 tightly against the bottom side of the discharge port to achieve partial closure of the discharge port, or drives the first driving rod 411 to retract, and the first discharge baffle 42 resets under the elastic action of the first spring arm 32, opening the corresponding discharge area; the second opening / closing actuator drives the second driving rod 431 to extend or retract, and similarly controls the opening and closing state of the second discharge baffle 44; the first vibrator 45 works to generate vibration, which helps the material slide down the surface of the first discharge baffle 42, reducing material accumulation; multiple sets of discharge components work independently, which can realize fine feeding of multiple channels and different amounts; during the feeding process, the angle of the support plate 3 can be finely adjusted by rotating the first adjusting nut, or the vibration parameters of the first vibrator 45 can be adjusted, according to the material falling situation, to ensure that the feeding process is stable and uniform. Through the above structural design, under the premise that the output rod of linear actuators such as cylinders or electric push rods has limited miniaturization, the fineness of the material discharge from hopper 2 is significantly improved through the synergistic effect of multiple compactly arranged discharge components, anti-interference design of the clearance groove, vibration auxiliary structure, and precision adjustment structure, thus meeting the requirements of high-precision feeding.

[0040] In addition, when full-scale discharge (i.e., discharge from the entire discharge port simultaneously) is required, the rotary drive can be activated to open the entire discharge port and achieve simultaneous discharge.
