Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a high-speed feeding device. Background Technology

[0002] Traditional rotary feeding devices are widely used in various automated production lines to transport materials to designated locations. These devices typically consist of a rotating turntable and several containers fixed on it.

[0003] However, this traditional rotary feeding device suffers from inefficiency when handling certain special materials, such as springs. Springs require a certain amount of time to stabilize and position during the feeding process. To accommodate this spring feeding time, traditional rotary feeding devices must reduce the rotation speed of the turntable. This reduction in turntable speed directly leads to a slower feeding speed, thus lowering overall production efficiency. Especially in large-scale automated production lines with high efficiency requirements, this inefficient feeding method becomes a bottleneck restricting capacity expansion.

[0004] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fast and efficient feeding device.

[0006] This utility model is achieved through the following technical solution:

[0007] To solve the above-mentioned technical problems, this utility model provides a high-speed feeding device, including a frame and a turntable assembly. The turntable assembly has multiple distributing holes around its periphery, and multiple feeding plates that can move intermittently in the circumferential direction are movably connected to the periphery of the turntable assembly. The feeding plates are located above the corresponding distributing holes, and each feeding plate has a storage hole that can be aligned with the corresponding distributing hole. The frame is equipped with a feeding device for feeding material into the storage holes, and a blocking device for temporarily blocking the corresponding feeding plate during the feeding process of the feeding device. An elastic connection structure is provided between the turntable assembly and each feeding plate. During the rotation of the turntable assembly, the elastic connection structure pulls the feeding plate, allowing the feeding plate to gradually overcome the resistance of the blocking device until it passes the blocking device, thereby achieving delayed control of the movement of the feeding plate.

[0008] To further address the technical problems to be solved by this utility model, this utility model provides a high-speed feeding device in which the elastic connection structure includes a tension elastic member connected between the turntable assembly and the corresponding feeding plate, and a limiting structure disposed between the turntable assembly and the corresponding feeding plate to limit the rotation range of the corresponding feeding plate.

[0009] To further solve the technical problem to be solved by this utility model, this utility model provides a high-speed feeding device in which the limiting structure includes a guide post on the turntable assembly and an arc-shaped waist-shaped hole on the feeding plate. The guide post is inserted into the corresponding waist-shaped hole and can slide therein. The tension elastic element is arranged between the corresponding guide post and another adjacent feeding plate opposite to the rotation direction of the turntable assembly.

[0010] To further address the technical problems addressed by this utility model, a high-speed feeding device is provided. The blocking device includes a blocking seat fixed to the frame and a blocking head slidably connected to the blocking seat and capable of approaching and moving away from the feeding plate. A first elastic reset member is provided between the blocking head and the blocking seat, elastically pressing the blocking head towards the feeding plate. A trigger member is provided on the feeding plate, and the blocking head extends towards and blocks the trigger member. When the turntable assembly rotates and drives the feeding plate, the trigger member is pulled outward by the elastic connection structure, gradually pushing the blocking head outward to overcome the resistance of the first elastic reset member and retract until it passes the blocking head.

[0011] In order to further solve the technical problem to be solved by this utility model, the high-speed feeding device provided by this utility model has a trigger element that is a guide wheel rotatably connected to the feeding plate, and the end of the blocking head is provided with an arc-shaped guide opening that matches the shape of the guide wheel.

[0012] To further address the technical problems addressed by this utility model, a high-speed feeding device is provided in which a screw is slidably connected to the barrier seat, the threaded end of the screw is threadedly connected to the barrier head, and an adjusting nut is also connected to the screw. The first elastic reset element is a compression spring sleeved on the screw and disposed between the adjusting nut and the barrier seat.

[0013] In order to further solve the technical problem to be solved by this utility model, this utility model provides a high-speed feeding device, wherein the feeding device includes a feeding base fixed on the frame, the feeding base is provided with a feeding pipe that can be aligned with the corresponding storage hole and feed material into it, and the lower end opening of the feeding pipe is provided with a blocking mechanism for releasing material one by one.

[0014] To further address the technical problems addressed by this invention, a high-speed feeding device is provided. The blocking mechanism includes a sliding seat slidably connected to a feeding base and capable of approaching and moving away from the feeding plate. A second elastic reset member is provided between the sliding seat and the feeding base, pulling the sliding seat towards the feeding plate. The sliding seat has a stop block that opens and closes the lower opening of the feeding tube as the sliding seat slides inward and outward. A trigger member is provided on the feeding plate, and a push head is provided on the sliding seat extending towards the trigger member and capable of being pushed outward by the trigger member. When the feeding plate moves to the feeding position, the trigger member pushes the push head, causing the sliding seat to move, thereby controlling the opening and closing of the stop block and achieving quantitative feeding of the material.

[0015] In order to further solve the technical problems to be solved by this utility model, the high-speed feeding device provided by this utility model has a trigger element that is a guide wheel rotatably connected to the feeding plate, and the push head has chamfers on both sides.

[0016] To further address the technical problems addressed by this utility model, a high-speed feeding device is provided in which a circumferential track groove is provided between the turntable assembly and the turntable assembly, and a roller that cooperates with the track groove is provided on the feeding plate, thereby guiding the feeding plate to move circumferentially around the turntable assembly.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. The core innovation of this utility model lies in the ingenious use of the cooperation between the elastic connection structure, the blocking device, and the triggering mechanism to achieve precise control of the material feeding plate's movement, thereby achieving stable and efficient material feeding on the high-speed rotating turntable assembly. The "uniform speed-dwell-accelerate" intermittent motion mode of the material feeding plate ensures sufficient feeding time for the feeding device while avoiding interference with subsequent feeding processes, significantly improving feeding accuracy and efficiency. In addition, the continuous rotation of the turntable assembly effectively reduces pause time, further enhancing the overall feeding speed.

[0019] 2. Another significant advantage of this invention lies in its purely mechanical and automated design. The feeding and blocking devices require no additional power source, relying entirely on the energy stored and released by the elastic connection structure for operation. This greatly simplifies the system structure, reduces manufacturing and maintenance costs, and improves the reliability and stability of the equipment, making it particularly suitable for harsh working environments. Furthermore, this design is more energy-efficient and environmentally friendly, aligning with the concept of sustainable development. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 5 As shown, this embodiment provides a high-speed feeding device applicable to high-speed lower springs. The high-speed feeding device includes a frame 1 and a turntable assembly 2. The turntable assembly 2 includes a synchronously rotating upper turntable 2a and a lower turntable 2b, which are fixed together by a connecting member. Multiple distributing holes 21 are evenly distributed around the periphery of the turntable assembly 2 to accommodate materials and discharge them to the next process.

[0028] Multiple feed plates 3 are movably connected to the periphery of the turntable assembly 2. To further improve the stability and smoothness of the feed plates 3's movement and reduce friction and wear during high-speed rotation, this invention designs circumferential track grooves 22 between the turntable assemblies 2. These track grooves 22 extend along the circumference of the turntable assembly 2, forming a continuous annular track.

[0029] In conjunction with the track groove 22, each feed plate 3 is equipped with a roller 33 that matches the shape of the track groove 22. These rollers 33 fit tightly with the track groove 22 and can roll along the track groove 22, thereby guiding the feed plate 3 to move smoothly along the circumference of the turntable assembly 2.

[0030] Each feeding plate 3 is located above the corresponding dispensing hole 21 and can move intermittently along the circumference of the turntable assembly 2. Each feeding plate 3 is provided with a storage hole 31. When the feeding plate 3 moves above the dispensing hole 21, the storage hole 31 can be aligned with the dispensing hole 21 so that the material falls into the dispensing hole 21.

[0031] A feeding device 4 is installed on one side of the turntable assembly 2 on the frame 1, which is used to fill the material into the storage hole 31 of the feeding plate 3. In order to ensure that the feeding device 4 has sufficient feeding time, a blocking device 5 is also provided on the frame 1. During the feeding process of the feeding device 4, the blocking device 5 can temporarily block the movement of the corresponding feeding plate 3 in sequence.

[0032] An elastic connection structure 6, such as a spring or elastic rope, is provided between the turntable assembly 2 and each feeding plate 3. When the turntable assembly 2 rotates, the corresponding feeding plate 3 is pulled by the elastic connection structure 6. When the feeding plate 3 rotates with the turntable assembly 2 to below the feeding device 4, it is temporarily blocked by the blocking device 5. At this time, the elastic connection structure 6 is in a stretched or compressed state, accumulating energy. As the turntable assembly 2 continues to rotate, the tension of the elastic connection structure 6 gradually increases, eventually overcoming the resistance of the blocking device 5, allowing the feeding plate 3 to pass over the blocking device 5 and complete the feeding process.

[0033] In this embodiment, the combined use of the elastic connecting structure 6 and the blocking device 5 enables precise control of the movement of the feeding plate 3. When the feeding plate 3 rotates to below the feeding device 4, the blocking device 5 causes it to pause briefly, providing sufficient feeding time for the feeding device 4 and ensuring the accuracy and stability of the feeding. It should be noted that during this period, the turntable assembly 2 continues to rotate without stopping. After the feeding plate 3 passes the blocking device 5, it quickly returns to its original position under the action of the elastic connecting structure 6, aligning with the corresponding dispensing hole 21, allowing the material to fall into the dispensing hole 21.

[0034] The movement trajectory of the feeding plate 3 exhibits an intermittent characteristic of "uniform speed-dwell-acceleration". This movement mode ensures both the stability of material feeding and improves feeding efficiency. The dwell time of the feeding plate 3 at the feeding position ensures sufficient feeding time, while its rapid return avoids interference with the subsequent feeding process, thus achieving high-speed and stable feeding.

[0035] Furthermore, in order to achieve more precise control over the movement of the feed plate 3, the elastic connection structure 6 includes a tension elastic element 61 and a limiting structure connected between the turntable assembly 2 and the corresponding feed plate 3.

[0036] The tension elastic element 61 is a component that provides elastic force, preferably a tension spring or an elastic rope. A tension spring can provide stable tension, while an elastic rope has greater flexibility, and the choice can be made according to actual needs.

[0037] The function of the limiting structure is to restrict the rotation range of the feed plate 3, ensuring it moves along a predetermined trajectory. The limiting structure of this invention includes a guide post 62 mounted on the turntable assembly 2 and an arc-shaped oblong hole 63 mounted on the feed plate 3. The guide post 62 inserts into the corresponding oblong hole 63 and slides within it.

[0038] Preferably, the tension elastic element 61 is positioned between the corresponding guide post 62 and another adjacent feed plate 3 rotating in the opposite direction to the rotation of the turntable assembly 2. This arrangement ensures that the tension direction of the tension elastic element 61 is always opposite to the rotation direction of the turntable assembly 2, thereby effectively controlling the movement of the feed plate 3. When the turntable assembly 2 rotates, the tension elastic element 61 is stretched, accumulating energy. When the feed plate 3 encounters the blocking device 5, the accumulated energy is used to overcome the resistance of the blocking device 5, allowing the feed plate 3 to pass over the blocking device 5.

[0039] The advantage of this design is that it allows for more precise control over the dwell time and return speed of the feed plate 3, thereby improving the accuracy and efficiency of the feed. At the same time, this structure is simple, reliable, and easy to manufacture and maintain.

[0040] To further improve the control accuracy and flexibility of the feeding process, the blocking device 5 includes a blocking seat 51 fixed on the frame 1 and a blocking head 52 slidably connected to the blocking seat 51 and capable of approaching and moving away from the feeding plate 3.

[0041] A first elastic reset element 53 (e.g., a spring) is provided between the blocking head 52 and the blocking seat 51. Its function is to elastically press the blocking head 52 toward the lower plate 3. When the lower plate 3 has not arrived, the blocking head 52 is in the extended state, ready to block the lower plate 3.

[0042] More specifically, a trigger element 32 is provided on the feed plate 3. The blocking head 52 extends toward and can block the trigger element 32. When the turntable assembly 2 rotates and drives the feed plate 3 to move, the trigger element 32, under the action of the elastic connection structure 6, gradually pushes the blocking head 52 outward, so that it overcomes the resistance of the first elastic reset element 53 and retracts until the feed plate 3 passes the blocking head 52.

[0043] Furthermore, to achieve smooth contact and release, the trigger 32 is designed as a guide wheel rotatably connected to the feed plate 3, while the end of the blocking head 52 is provided with an arc-shaped guide opening 521 that matches the shape of the guide wheel. When the guide wheel contacts the blocking head 52, it will roll along the arc-shaped guide opening 521, thereby smoothly pushing the blocking head 52 away and avoiding direct collision and impact.

[0044] To achieve fine adjustment of the position of the blocking head 52, a screw 54 is slidably connected to the blocking seat 51, with its threaded end threadedly connected to the blocking head 52. An adjusting nut 55 is also connected to the screw 54. By rotating the adjusting nut 55, the position of the blocking head 52 can be changed, as can the initial compression length of the first elastic reset member 53, thereby precisely adjusting the elastic force of the first elastic reset member 53. The first elastic reset member 53 is designed as a compression spring sleeved on the screw 54 and positioned between the adjusting nut 55 and the blocking seat 51. This design makes adjusting the adjusting nut 55 more convenient, and the compression spring provides a stable restoring force, allowing the blocking head 52 to quickly return to its initial position after release.

[0045] Through the above improvements, the blocking device 5 achieves more precise control over the movement of the feeding plate 3. It can adjust the position and resetting force of the blocking head 52 according to different materials and feeding speeds, thereby improving feeding efficiency and accuracy. This makes the feeding process more flexible, controllable, and adaptable.

[0046] To achieve precise material supply, the design of the feeding device 4 has also been improved accordingly. The feeding device 4 includes a feeding base 41 fixed on the frame 1, and a feeding pipe 42 is provided on the feeding base 41, which can be aligned with the corresponding storage hole 31 and put the material into the storage hole 31. In order to achieve quantitative feeding of material, a blocking mechanism is provided at the lower opening of the feeding pipe 42.

[0047] The release mechanism includes a sliding seat 43 slidably connected to the feeding base 41 and capable of approaching and moving away from the feed plate 3. A second elastic reset member 44 is provided between the sliding seat 43 and the feeding base 41, which pulls the sliding seat 43 towards the feed plate 3, keeping the release mechanism in a ready state. A stop block 431 is provided on the sliding seat 43, which can open and close the lower end opening of the feeding pipe 42 as the sliding seat 43 slides inward and outward, thereby controlling the release of material.

[0048] To achieve automated control of material feeding, a trigger element 32 (the same component as the trigger element mentioned above, but it can also be a different component) is provided on the feeding plate 3, and a push head 432 extending towards the trigger element 32 is provided on the sliding seat 43. When the turntable assembly 2 moves the feeding plate 3 to the feeding position, the trigger element 32 pushes the push head 432, which in turn moves the sliding seat 43, thereby controlling the opening and closing of the stop block 431 and realizing the quantitative feeding of materials.

[0049] Furthermore, to ensure the smoothness and reliability of the triggering process, the trigger element 32 is designed as a guide wheel rotatably connected to the feed plate 3, while the push head 432 has chamfers on both sides. This design allows the guide wheel to smoothly push the push head 432, avoiding jamming and impact, and improving the reliability and service life of the triggering mechanism.

[0050] Through the above improvements, the feeding device 4 can achieve quantitative and automatic material feeding. When the feeding plate 3 reaches the feeding position, the trigger mechanism is activated, and the material is quantitatively released into the storage hole 31. After the feeding plate 3 leaves the feeding position, the second elastic reset member 44 will pull the sliding seat 43 back to the initial position, and the stop block 431 will close the lower opening of the feeding pipe 42, thereby stopping the material feeding and preparing for the next feeding action.

[0051] It is worth noting that a significant advantage of this invention lies in its high degree of mechanical automation. Both the feeding device 4 and the blocking device 5 adopt a purely mechanical structure design, requiring no additional motors, cylinders, or other power sources for drive. Their operation relies entirely on the power provided by the elastic connection structure 6 and the movement of the feeding plate 3, cleverly transforming the rotational motion of the turntable assembly 2 into feeding and blocking actions.

[0052] Specifically, the elastic potential energy stored in the elastic connection structure 6 is key to driving the feeding device 4 and the blocking device 5. The rotation of the turntable assembly 2 drives the feeding plate 3 to move, and then, through the interaction between the trigger 32 and the feeding device 4 and the blocking device 5, the energy stored in the elastic connection structure 6 is released, driving the corresponding mechanical structure to complete the feeding and blocking actions.

[0053] This purely mechanically driven design concept offers numerous benefits: Simplified structure and reduced costs: Eliminating the need for an additional drive unit simplifies the overall system structure, reducing manufacturing and maintenance costs. Improved reliability: Reduced reliance on electronic components and complex control systems enhances equipment reliability and stability, especially in harsh working environments. Energy efficiency and environmental friendliness: Requires no additional energy consumption, making it more energy-efficient and environmentally friendly. Ease of operation and maintenance: The purely mechanical structure is easy to understand and operate, and maintenance is also simpler and more convenient.
