Description

Technical Field

[0001] This invention belongs to the field of solid powder feeding technology, specifically relating to a solid powder feeding device and feeding method. Background Technology

[0002] In laboratory and precision batching fields, solid powder feeding equipment typically uses vibration, screw conveyors, or rotary valves to achieve quantitative powder output. Such equipment generally includes a feeding head, a drive mechanism, and a receiving container. The feeding head vibrates or rotates to cause the powder to fall from the outlet into a receiving bucket or beaker below, with real-time feedback from an electronic balance. To reduce powder scattering and electrostatic adsorption, some equipment has ionizers near the outlet; to prevent residual powder from falling into the weighed container after feeding, manual wiping, air blowing, or simple baffles are also used for cleaning.

[0003] However, existing solid powder feeding equipment still has shortcomings in terms of overall integration, operational coordination, and feeding accuracy. On the one hand, functions such as vibration feeding, ion wind static elimination, and residual powder collection are usually implemented by independent mechanisms, resulting in a complex overall structure, a large number of parts, and difficulty in forming effective linkage and strict synchronization between various actions. Powder is still prone to scattering or adhering due to static electricity during the falling process, affecting feeding accuracy and environmental cleanliness. On the other hand, the installation and fixation reliability of the feeding head under vibration conditions is insufficient, and residual powder at the outlet after feeding can easily fall into the weighed container accidentally, further affecting the measurement accuracy and making it difficult to meet the high-precision addition requirements of laboratories for trace, valuable, or harmful powders.

[0004] Therefore, there is an urgent need for a solid powder feeding device that can coordinate and unify key actions such as vibration feeding, ion wind static elimination, and residual powder collection through integrated and linked design, simplifying the overall structure and improving the synchronization of actions; at the same time, it can improve the installation stability of the feeding head and the ability to prevent residual powder from falling, fundamentally improving the accuracy, cleanliness, and automation level of solid powder feeding. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a solid powder feeding device and feeding method, which uses a single rotary drive mechanism to drive an integrated drive disk, and synchronously link three actions: vibration and knocking of the feeding head, oscillation and static elimination of the ion air bar, and avoidance and resetting of the receiving cup, so as to achieve high precision, high cleanliness and high automation of powder feeding.

[0006] This invention provides a solid powder feeding device, including a feeding head, the feeding head having a discharge nozzle, and further comprising: Rotary drive mechanism; The drive disk is driven to rotate by the rotary drive mechanism. The front end face of the drive disk is fixedly provided with a first cam structure, the outer peripheral surface of the drive disk is fixedly provided with a second cam structure, and the center of the drive disk is fixedly provided with a rotating shaft. The first vibration mechanism includes a first transmission component, one end of which abuts against the first cam structure, and the other end is used to strike the feeding head; The ion blower mechanism includes an ion blower bar and a second transmission assembly. The ion blower bar is hinged to the side of the feeding head via a mounting plate. One end of the second transmission assembly is slidably engaged with the second cam structure, and the other end is connected to the ion blower bar so as to drive the ion blower bar to swing when the drive disc rotates. The receiving cup assembly includes a receiving cup and a third transmission assembly. One end of the third transmission assembly is connected to the rotating shaft, and the other end is connected to the receiving cup. When the drive disc rotates, the receiving cup is first driven away from below the discharge nozzle and then limited. When the drive disc stops rotating, it is reset to below the discharge nozzle.

[0007] Furthermore, the third transmission assembly includes a damping ring, a first torsion spring, and an intermediate shaft. The damping ring is sleeved on the rotating shaft and frictionally engages with the rotating shaft. The intermediate shaft is fixedly connected to the damping ring and is connected to the receiving cup. One end of the first torsion spring is fixedly disposed, and the other end is connected to the intermediate shaft. The first torsion spring is used to drive the intermediate shaft to rotate in the opposite direction when the rotating shaft stops rotating, so that the receiving cup is reset to below the discharge nozzle.

[0008] Furthermore, the third transmission assembly also includes a bevel gear assembly and a swing arm. The driving bevel gear of the bevel gear assembly is fixed on the intermediate shaft, and the driven bevel gear of the bevel gear assembly is fixed on the rotation shaft of the swing arm. The rotation shaft of the swing arm is rotatably mounted on the equipment frame, and the receiving cup is fixed to the end of the swing arm.

[0009] Furthermore, the receiving cup is rotatably connected to the swing arm, and the center of gravity of the receiving cup is lower than the rotatable connection point between it and the swing arm, so that the receiving cup is always in a horizontal position under the action of gravity.

[0010] Furthermore, the second transmission assembly includes a guide rod, a sliding frame, a connecting finger, and a connecting bracket. One end of the guide rod is slidably engaged with the second cam structure, and the other end is fixedly connected to the sliding frame. The sliding frame is slidably arranged up and down. One end of the connecting finger is fixedly connected to the sliding frame, and the other end is slidably engaged with the connecting bracket. The connecting bracket is fixedly connected to the mounting plate.

[0011] Furthermore, two ion air bars are provided, and the two ion air bars are symmetrically hinged on both sides of the feeding head; two sets of the second transmission components are provided accordingly, and each set of the second transmission components includes a guide rod, a sliding frame, a connecting finger, and a connecting frame; the two guide rods are integrally connected.

[0012] Furthermore, the first transmission assembly includes a sliding rod and a first elastic element. The sliding rod is slidably arranged laterally, with one end abutting against the first cam structure and the other end used to strike the feeding head. One end of the first elastic element is fixedly arranged, and the other end is connected to the sliding rod to keep the sliding rod abutting against the first cam structure.

[0013] Furthermore, it also includes a frame, on which a first lifting mechanism is provided. The first lifting mechanism includes a liftable first lifting frame and a mounting frame fixed on the first lifting frame. The feeding head is disposed on the mounting frame. The feeding head includes a housing, a top cover fixed to the top of the housing, and a shaft core that is rotatable and axially slidably inserted into the housing. The shaft core is provided with a spiral guide groove and a docking groove at the top. A second elastic element is provided between the shaft core and the housing. The second elastic element causes the shaft core to have an upward reset tendency. It also includes a docking drive mechanism, which is mounted on the frame or the first lifting frame. The output end of the docking drive mechanism is connected to a second lifting frame that can be raised and lowered relative to the feeding head.

[0014] Furthermore, it also includes a vertical vibration mechanism, which is installed on the second lifting frame. The vertical vibration mechanism includes a vertical vibration drive device, a rotating shaft driven by the vertical vibration drive device, a lifting rod that is circumferentially fixed and axially slidably connected to the rotating shaft, a male connector fixed to the lower end of the lifting rod, a contact plate fixed to the upper end of the lifting rod, and a contact head fixed relative to the second lifting frame. The end face of the contact plate is provided with a toothed groove, and the contact head abuts against the toothed groove. When the second lifting frame descends, the male connector engages with the mating groove and presses down on the shaft core. The vertical vibration drive device drives the lifting rod and the male connector to rotate through the rotating shaft. At the same time, the cooperation between the contact plate and the contact head causes the lifting rod to generate axial vibration, thereby driving the shaft core to rotate synchronously and vibrate axially.

[0015] The present invention also provides a solid powder feeding method, which uses the above-mentioned solid powder feeding equipment and includes the following steps: Start the rotary drive mechanism to make the drive disc rotate; During the rotation of the drive disc, the first cam structure strikes the feeding head through the first transmission component, the second cam structure drives the ion air bar to swing through the second transmission component, and at the same time the rotating shaft drives the receiving cup to move away from below the discharge nozzle and limit it through the third transmission component. Solid powder is fed through a feeding head; After feeding is completed, the rotating drive mechanism stops, the drive disc stops rotating, and the third transmission component drives the receiving cup to return to below the discharge nozzle to receive the powder remaining on the discharge nozzle.

[0016] The solid powder feeding device provided by this invention has the following advantages compared with the prior art: 1. The first vibration mechanism of the present invention, through the cooperation of the first cam structure and the first transmission component, converts the rotational motion of the drive disc into intermittent knocking on the feeding head, causing the feeding head to vibrate laterally, effectively breaking the bridging and arching phenomena formed by the powder material inside the feeding head, and ensuring unobstructed feeding channel; the ion fan mechanism, through the linkage of the second cam structure and the second transmission component, causes the ion fan bar to continuously swing during the feeding process, and the ion fan dynamically covers the discharge area, eliminating the static electricity generated by friction during the powder falling, and reducing the static adsorption of powder on the discharge nozzle, the inner wall of the receiving hopper, and the surface of the equipment; the receiving cup assembly, through the cooperation of the rotating shaft and the third transmission component, automatically avoids the discharge path before feeding begins, and automatically resets to receive the residual powder on the discharge nozzle after feeding ends, preventing residual powder from falling into the receiving hopper and causing secondary pollution.

[0017] 2. All three mechanisms are driven by the same drive disc. The vibration, ion air blowing, and receiving cup avoidance and reset actions are naturally synchronized in time, achieving action matching without the need for an additional control system or timing programming. The vibration of the feeding head and the oscillation of the ion air bar are synchronized. The vibration loosens the powder and causes it to fall, while the ion air acts on both the falling powder and the discharge nozzle area. The two complement each other in time and space: if the powder disturbance generated by the vibration is not eliminated by static electricity, it can easily cause powder to scatter, but the dynamic blowing of the ion air suppresses this side effect; if the ion air acts alone on the static discharge nozzle, its effect on removing powder adhering to the inside is limited, but the vibration loosens the adhering powder, creating a synergistic removal effect with the ion air. The reset action of the receiving cup is synchronized with the stopping of the vibration and the ion air, ensuring that the residual powder loosened by the vibration and ion air on the discharge nozzle after feeding is caught by the receiving cup, preventing residual powder from falling into the weighed receiving bucket.

[0018] 3. This invention uses a single rotary drive mechanism as the power source, simultaneously driving the vibration, ionization air, and receiving cup mechanisms through a single drive disc. This highly integrated structure reduces the number of drive components, lowers manufacturing costs and the number of potential failure points, and improves the overall reliability and ease of maintenance. Since all three actions originate from the same rotary motion, there are no timing deviations or response delays that might occur between mechanisms due to independent driving, fundamentally ensuring the consistency and repeatability of the actions.

[0019] 4. The vibration mechanism ensures continuous and uniform powder descent, avoiding fluctuations in feed volume caused by bridging or blockage; the ion fan mechanism eliminates static electricity, allowing powder to fall steadily into the receiving hopper along a predetermined path, reducing material loss caused by scattering and spillage; the receiving cup assembly collects any residual powder that may fall from the discharge nozzle after feeding, eliminating interference from residual powder on the final weighing result. These three components eliminate different sources of error affecting metering accuracy in both the feeding process and after feeding, achieving a systematic improvement in feeding accuracy.

[0020] 5. This equipment is particularly suitable for the precise addition of trace, valuable, or toxic / hazardous solid powders in laboratory environments. Trace powders require extremely high feeding precision; any residual powder falling or scattering will cause significant relative errors. The receiving cup assembly and ion fan mechanism of this invention control this source of error from two dimensions: physical interception and electrostatic suppression, respectively. Valuable powders have low tolerance for material loss; ion fan reduces scattering, and vibration promotes complete feeding, jointly improving material utilization. Hazardous powders have strict requirements for operational safety and environmental cleanliness; ion fan suppresses powder scattering, and the receiving cup prevents residual powder from falling, reducing the escape of powder into the external environment from the source.

[0027] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0028] like Figures 1-9 As shown, the present invention provides a solid powder feeding device, including a feeding head 1, the feeding head 1 having a discharge nozzle 101, and further comprising: Rotary drive mechanism 2; Rotary drive mechanism 2 is used to provide the rotational power required for the entire equipment, drive drive disk 3 to rotate, and make each linkage mechanism move synchronously.

[0029] The drive disk 3 is driven to rotate by the rotary drive mechanism 2. The front end face of the drive disk 3 is fixedly provided with a first cam structure 301, the outer peripheral surface of the drive disk 3 is fixedly provided with a second cam structure 302, and the center of the drive disk 3 is fixedly provided with a rotating shaft 303. As an integrated drive component, the drive disk 3 distributes the rotational motion to three functional components: vibration, ion wind, and receiving cup, to achieve a linkage effect of multiple movements on one axis.

[0030] The first vibration mechanism 4 includes a first transmission component 401. One end of the first transmission component 401 abuts against the first cam structure 301, and the other end is used to strike the feeding head 1. When the drive disk 3 rotates, the first cam structure 301 converts the rotational motion into intermittent striking of the feeding head 1 through the first transmission component 401, causing the feeding head 1 to vibrate, thereby preventing the powder material from clogging or adhering inside the feeding head and ensuring the continuity and uniformity of feeding.

[0031] The ion fan mechanism 5 includes an ion fan bar 501 and a second transmission component 502. The ion fan bar 501 is hinged to the side of the feeding head 1 via a mounting plate 503. One end of the second transmission component 502 is slidably engaged with the second cam structure 302, and the other end is connected to the ion fan bar 501 so that the ion fan bar 501 can swing when the drive disk 3 rotates. The rotation of the drive disk 3 simultaneously drives the ion fan bar 501 to swing, so that the ion fan can dynamically cover the discharge area, effectively eliminate the static electricity generated during the powder falling process, prevent the powder from drifting or adhering to the discharge nozzle 101 and the edge of the receiving container, and improve the feeding accuracy and environmental cleanliness.

[0032] The receiving cup assembly 6 includes a receiving cup 601 and a third transmission assembly 602. One end of the third transmission assembly 602 is connected to the rotating shaft 303, and the other end is connected to the receiving cup 601. When the drive disk 3 rotates, it first drives the receiving cup 601 away from below the discharge nozzle 101 and then limits it. When the drive disk 3 stops rotating, it returns to below the discharge nozzle 101. When feeding begins, the receiving cup 601 automatically moves away to ensure a smooth feeding path. After feeding ends, the receiving cup 601 automatically returns to below the discharge nozzle 101 to receive residual or fallen powder on the discharge nozzle 101, preventing residual powder from falling into the already fed receiving bucket 12, thereby significantly improving the accuracy and repeatability of feeding.

[0033] The solid powder feeding device provided by this invention has the following advantages compared with the prior art: 1. The first vibration mechanism 4 of the present invention, through the cooperation of the first cam structure 301 and the first transmission component 401, converts the rotational motion of the drive disk 3 into intermittent knocking on the feeding head 1, causing the feeding head 1 to vibrate laterally, effectively breaking the bridging and arching phenomenon formed by the powder material inside the feeding head 1, and ensuring that the feeding channel is unobstructed; the ion fan mechanism 5, through the linkage of the second cam structure 302 and the second transmission component 502, causes the ion fan bar 501 to swing continuously during the feeding process, and the ion fan dynamically covers the discharge area, eliminating the static electricity generated by friction during the powder falling, and reducing the static adsorption of powder on the discharge nozzle 101, the inner wall of the receiving bucket 12 and the surface of the equipment; the receiving cup assembly 6, through the cooperation of the rotating shaft 303 and the third transmission component 602, automatically avoids the discharge path before feeding begins, and automatically resets to receive the residual powder on the discharge nozzle 101 after feeding ends, preventing residual powder from falling into the receiving bucket 12 and causing secondary pollution.

[0034] 2. The three mechanisms are uniformly driven by the same drive disc 3. The three actions of vibration knocking, ion air blowing, and material cup avoidance and reset are naturally synchronized in time, achieving action matching without the need for an additional control system or timing programming. The vibration of the feeding head 1 and the swing of the ion air bar 501 are synchronized. The vibration loosens the powder and causes it to fall, while the ion air acts on both the falling powder and the area of ​​the discharge nozzle 101. The two complement each other in time and space: if the powder disturbance generated by the vibration is not eliminated by static electricity, it can easily cause the powder to scatter, while the dynamic blowing of the ion air suppresses this side effect; if the ion air acts alone on the static discharge nozzle, the effect of removing powder adhering inside is limited, while the vibration loosens the adhering powder, forming a synergistic removal effect with the ion air. The reset action of the material cup 601 is synchronized with the stopping of vibration and ion air, ensuring that the residual powder loosened by vibration and ion air on the discharge nozzle 101 after feeding is caught by the material cup 601, preventing residual powder from falling into the weighed material collection bucket 12.

[0035] 3. This invention uses a single rotary drive mechanism 2 as the power source, and simultaneously drives the vibration, ionization wind, and receiving cup mechanisms through a single drive disk 3. The highly integrated structure reduces the number of drive components, lowers equipment manufacturing costs and the number of potential failure points, and improves the overall reliability and ease of maintenance. Since all three actions originate from the same rotary motion, there are no timing deviations or response delays that might occur between the mechanisms due to independent driving, fundamentally ensuring the consistency and repeatability of the actions.

[0036] 4. The first vibration mechanism 4 ensures continuous and uniform powder drop, avoiding fluctuations in the feeding amount caused by bridging or blockage; the ion fan mechanism 5 eliminates static electricity, allowing the powder to fall stably into the receiving hopper 12 along a predetermined path, reducing material loss caused by scattering and spillage; the receiving cup assembly 6 collects any residual powder that may fall from the discharge nozzle 101 after feeding, eliminating interference from residual powder on the final weighing result. These three components eliminate different sources of error affecting metering accuracy during and after feeding, achieving a systematic improvement in feeding accuracy.

[0037] 5. This equipment is particularly suitable for the precise addition of trace, valuable, or toxic / hazardous solid powders in laboratory environments. Trace powders require extremely high feeding precision; any residual powder falling or scattering will cause significant relative errors. The receiving cup assembly 6 and ion fan mechanism 5 of this invention control this source of error from two dimensions: physical interception and electrostatic suppression, respectively. Valuable powders have low tolerance for material loss; ion fan reduces scattering, and vibration promotes complete feeding, jointly improving material utilization. Hazardous powders have strict requirements for operational safety and environmental cleanliness; ion fan suppresses powder scattering, and the receiving cup prevents residual powder from falling, reducing the escape of powder into the external environment from the source.

[0038] In one embodiment, the third transmission assembly 602 includes a damping ring 6021, a first torsion spring 6022, and an intermediate shaft 6023. The damping ring 6021 is sleeved on the rotating shaft 303 and frictionally engages with the rotating shaft 303. A frictional damping engagement is formed between the damping ring 6021 and the rotating shaft 303, which can transmit torque to drive the intermediate shaft 6023 to rotate when the rotating shaft 303 rotates, and can also cause slippage when the rotating shaft 303 continues to rotate, keeping the receiving cup 601 in a clearance position. The intermediate shaft 6023 is fixedly connected to the damping ring 6021. The receiving cup 601 is connected, and the intermediate shaft 6023 acts as a transmission medium to transmit the rotational motion of the rotating shaft 303 to the receiving cup 601, so as to realize the swing avoidance of the receiving cup 601; one end of the first torsion spring 6022 is fixedly set, and the other end is connected to the intermediate shaft 6023. The first torsion spring 6022 is used to provide a reset torque when the rotating shaft 303 stops rotating, to overcome the residual frictional resistance of the damping ring 6021. The first torsion spring 6022 is used to drive the intermediate shaft 6023 to rotate in the opposite direction when the rotating shaft 303 stops rotating, so that the receiving cup 601 is reset to below the discharge nozzle 101.

[0039] This embodiment utilizes the frictional engagement between the damping ring 6021 and the rotating shaft 303 to achieve torque transmission and slippage limiting, allowing the receiving cup 601 to automatically move away from the discharge path at the start of feeding and automatically return to its original position below the discharge nozzle 101 by the first torsion spring 6022 after feeding to collect residual powder. The overall structure is simple and reliable, achieving synchronous linkage between the receiving cup 601 and the feeding action without the need for additional sensors or control components. This effectively prevents residual powder from falling into the receiving hopper 12 and causing metering errors, improving feeding accuracy and the degree of equipment automation.

[0040] In one embodiment, the third transmission assembly 602 further includes a bevel gear assembly 6024 and a swing arm 6025. The driving bevel gear of the bevel gear assembly 6024 is fixed to the intermediate shaft 6023 and rotates with the intermediate shaft 6023, inputting rotational power into the bevel gear assembly 6024. The driven bevel gear of the bevel gear assembly 6024 is fixed to the rotation shaft of the swing arm 6025. The bevel gear assembly 6024 converts the rotation of the intermediate shaft 6023 about the horizontal axis into the swinging of the swing arm 6025 about its rotation shaft. The power direction is reversed; the rotating shaft of the swing arm 6025 is rotatably mounted on the equipment frame (specifically, it is rotatably mounted on the mounting frame 802). The swing arm 6025 swings around the rotating shaft as the fulcrum, driving the receiving cup 601 to reciprocate between the discharge nozzle 101 and the avoidance position. The receiving cup 601 is fixed to the end of the swing arm 6025. The receiving cup 601 swings synchronously with the swing arm 6025. When feeding begins, it moves away from below the discharge nozzle 101. After feeding ends, it returns to below the discharge nozzle 101 to receive residual powder.

[0041] In this embodiment, the rotational motion of the intermediate shaft 6023 is converted into the swinging motion of the swing arm 6025 through the bevel gear assembly 6024, so that the receiving cup 601 can reliably switch between the position below the discharge nozzle 101 and the avoidance position. The transmission direction conversion is accurate and the structure is compact. The lever structure of the swing arm 6025 amplifies the rotation angle of the intermediate shaft 6023, so that the receiving cup 601 can obtain sufficient swing stroke, thereby ensuring that the receiving cup 601 is completely separated from the discharge path and accurately resets to receive residual powder after feeding.

[0042] In one embodiment, the receiving cup 601 is rotatably connected to the swing arm 6025, and the center of gravity of the receiving cup 601 is lower than the rotatable connection point with the swing arm 6025, so that the receiving cup 601 always remains horizontal under the action of gravity. The rotatable connection between the receiving cup 601 and the swing arm 6025 allows the receiving cup 601 to swing freely around the rotatable connection point; since the center of gravity of the receiving cup 601 is lower than the rotatable connection point, a gravity self-leveling structure is formed. No matter how the swing arm 6025 swings, the receiving cup 601 can automatically maintain a horizontal posture with the cup opening facing upward under the action of gravity, avoiding tilting of the receiving cup 601 during the swinging process and ensuring that the collected residual powder will not spill.

[0043] This embodiment achieves adaptive horizontal maintenance of the receiving cup 601 during the movement of the swing arm 6025 by rotatably connecting the receiving cup 601 to the swing arm 6025 and setting the center of gravity of the receiving cup 601 below the rotatable connection point. This structure requires no additional power or control components; gravity alone keeps the receiving cup 601 in a horizontal position, ensuring that the cup opening remains stably upward during avoidance and resetting processes. This effectively prevents residual powder from spilling due to tilting, improving the reliability of residual powder collection and the accuracy of feeding metering.

[0044] In one embodiment, the receiving cup 601 is also provided with bristles, which are disposed on the edge of the cup mouth or the inner wall of the receiving cup 601. The bristles are used to contact the outer wall of the discharge nozzle 101 when the receiving cup 601 is reset below the discharge nozzle 101. When the receiving cup 601 is at the bottom of the discharge nozzle 101, the bristles can brush the discharge nozzle 101. Through the relative friction between the bristles and the discharge nozzle 101, the residual powder adhering to the outer wall or lower end of the discharge nozzle 101 is brushed off into the receiving cup 601, thereby keeping the discharge nozzle 101 clean and reducing the accumulation of powder on the discharge nozzle 101.

[0045] This embodiment incorporates bristles on the receiving cup 601, allowing it to simultaneously brush the discharge nozzle 101 as the cup resets below it. This removes residual powder adhering to the nozzle and collects it within the receiving cup 601. This structure utilizes the resetting motion of the receiving cup 601 to automatically clean the discharge nozzle 101, eliminating the need for a separate cleaning mechanism. The structure is simple, reliable, and effectively prevents residual powder from accidentally falling from the nozzle 101 during subsequent operations, further improving the accuracy of feeding and the cleanliness of the equipment.

[0046] In one embodiment, the second transmission assembly 502 includes a guide rod 5021, a sliding frame 5022, a connecting finger 5023, and a connecting frame 5024. One end of the guide rod 5021 is slidably engaged with the second cam structure 302, and the guide rod 5021 acts as a cam follower, moving along its contour trajectory when the second cam structure 302 rotates, converting the rotational motion of the drive disk 3 into the up-and-down reciprocating motion of the guide rod 5021. The other end is fixedly connected to the sliding frame 5022, and the guide rod 5021 drives the sliding frame 5022 to slide up and down synchronously. The sliding frame 5022 is slidably arranged up and down, providing linear guidance for the reciprocating motion of the guide rod 5021. This allows the movement of the guide rod 5021 to be stably transmitted to the downstream transmission component. One end of the connecting finger 5023 is fixedly connected to the sliding frame 5022, and the other end is slidably engaged with the connecting frame 5024. The connecting finger 5023 moves up and down with the sliding frame 5022, while its other end slides in the groove of the connecting frame 5024, converting the linear reciprocating motion of the sliding frame 5022 into the swing motion of the connecting frame 5024 and the mounting plate 503. The connecting frame 5024 is fixedly connected to the mounting plate 503, and the connecting frame 5024 drives the mounting plate 503 to swing around its hinge axis, thereby causing the ion wind bar 501 on the mounting plate 503 to swing synchronously, realizing the dynamic sweeping of the discharge area by the ion wind.

[0047] In this embodiment, the rotational motion of the second cam structure 302 is precisely converted into the reciprocating oscillation of the ion air bar 501 through the sequential transmission of the guide rod 5021, the sliding frame 5022, the connecting finger 5023, and the connecting frame 5024. The transmission chain structure is simple and reliable. Moreover, the oscillation of the ion air bar 501 is strictly synchronized with the rotation of the drive disk 3, ensuring that the ion air continuously and dynamically covers the outlet area throughout the entire process of feeding the material with the vibrating feeding head, effectively eliminating static electricity in the powder and improving feeding accuracy and cleanliness.

[0048] In one embodiment, two ion air bars 501 are provided, and the two ion air bars 501 are symmetrically hinged on both sides of the feeding head 1. The two ion air bars 501 are symmetrically arranged and blow ion air into the discharge nozzle area from both sides simultaneously to form a covering antistatic airflow for the discharged powder, eliminating static dead zones on the powder's falling path. The second transmission component 502 is provided in two sets, and each set of the second transmission component 502 includes a guide rod 5021, a sliding frame 5022, a connecting finger 5023, and a connecting frame 5024. The two sets of second transmission components 502 drive the two ion air bars 501 respectively, so that the two ion air bars 501 obtain swing power synchronously, ensuring that the ion air movements on both sides are consistent. The two guide rods 5021 are integrally connected, and the integral connection of the two guide rods 5021 allows the two sets of second transmission components 502 to share the same cam driven end and move up and down synchronously under the drive of the same second cam structure 302, thereby ensuring that the swing rhythm of the two ion air bars 501 is completely consistent and avoiding movement deviations caused by manufacturing or assembly errors.

[0049] This embodiment achieves synchronous swinging of the two ion air bars 501 and simultaneous blowing on both sides by symmetrically arranging them on both sides of the feeding head 1 and driving them separately by two sets of second transmission components 502. The two guide rods 5021 are integrally connected, which realizes the synchronous swinging of the two ion air bars 501 and simultaneous blowing on both sides. The ion air coverage is more comprehensive and the static electricity removal effect is better. At the same time, the integral connection of the two guide rods 5021 reduces the number of parts, makes the structure more compact, and improves the synchronization of the action, which is conducive to improving the working stability of the ion air device and the overall static electricity removal efficiency.

[0050] In one embodiment, the first transmission assembly 401 includes a sliding rod 4011 and a first elastic element 4012. The sliding rod 4011 is laterally slidable and reciprocates along the radial direction of the feeding head 1, converting the rotational profile change of the first cam structure 301 into a linear striking action. One end of the sliding rod 4011 abuts against the first cam structure 301, and the abutting end of the sliding rod 4011 acts as a cam follower, moving back and forth with the contour undulation of the first cam structure 301. The other end is used to strike the feeding head 1, and the striking end intermittently impacts the side wall of the feeding head 1 under the drive of the cam, causing the feeding head 1 to strike the feed head 1. The feed head 1 generates lateral vibration to prevent powder from bridging or adhering inside the feed head; one end of the first elastic member 4012 is fixedly set, and the other end is connected to the sliding rod 4011. The first elastic member 4012 applies an elastic force to the sliding rod 4011 toward the first cam structure 301, so that the abutting end of the sliding rod 4011 is always in close contact with the first cam structure 301. This is used to keep the sliding rod 4011 abutting against the first cam structure 301, thereby ensuring that the sliding rod 4011 can completely follow the contour movement of the first cam structure 301 and avoid knocking failure or action lag caused by contact gap.

[0051] This embodiment uses the cooperation of the sliding rod 4011 and the first elastic element 4012 to stably convert the rotational motion of the first cam structure 301 into a lateral reciprocating impact on the feeding head 1. The structure is simple and the response is rapid. The pre-pressure of the first elastic element 4012 ensures reliable contact between the sliding rod 4011 and the first cam structure 301, so that the impact action is strictly synchronized with the rotation of the drive disk 3. The impact vibration effectively destroys the bridging and arching of the powder, improves the continuity and uniformity of the feeding head, and thus improves the feeding accuracy and working stability of the solid powder feeding equipment.

[0052] In one embodiment, a frame 7 is also included. The frame 7 serves as the basic support structure of the equipment, used to install and support various functional components, ensuring the relative positional accuracy between the mechanisms. A first lifting mechanism 8 is provided on the frame 7. The first lifting mechanism 8 is used to drive the feeding head 1 to lift as a whole, adjusting the relative height between the feeding head 1 and the receiving hopper 12 to accommodate different sizes of receiving containers. The first lifting mechanism 8 includes a liftable first lifting frame 801 and a mounting frame 802 fixed on the first lifting frame 801. The first lifting frame 801 provides the lifting motion carrier, and the mounting frame 802 is used to fix the feeding head 1. The feeding head 1 is disposed on the mounting frame 802, and the feeding head 1 lifts and lowers synchronously with the first lifting frame 801 via the mounting frame 802. The feeding head 1 includes a housing 102 and a component fixed to the housing 102. 2. A top cover 103 and a shaft core 104 rotatably and axially slidably inserted into a housing 102. The housing 102 forms a cavity for containing powder. The top cover 103 closes the top of the housing 102. The shaft core 104 is inserted into the housing 102 to control the discharge. The shaft core 104 is provided with a spiral guide groove 1041 and a docking groove 1042 at the top. The spiral guide groove 1041 pushes the powder downward when the shaft core 104 rotates. The docking groove 1042 is used to dock with the docking male head 1004 to transmit rotation and axial movement. A second elastic element 105 is provided between the shaft core 104 and the housing 102. The second elastic element 105 gives the shaft core 104 a tendency to return to its original position. The second elastic element 105 provides a restoring force so that the shaft core 104 returns to the closed position when there is no external force, preventing powder leakage when not being fed. It also includes a docking drive mechanism 9, which is mounted on the frame 7 or the first lifting frame 801. The docking drive mechanism 9 is used to drive the second lifting frame 901 to move up and down, so as to realize the docking and separation of the vertical vibration mechanism and the feeding head 1. The output end of the docking drive mechanism 9 is connected to the second lifting frame 901, which can be raised and lowered relative to the feeding head 1. The second lifting frame 901 serves as the mounting carrier of the vertical vibration mechanism. The docking drive mechanism 9 realizes precise vertical displacement, so that the vertical vibration mechanism can accurately dock with the shaft core 104 of the feeding head 1.

[0053] This embodiment constructs a complete feeding head lifting and docking system through the cooperation of the frame 7, the first lifting mechanism 8, the feeding head 1, and the docking drive mechanism 9. This allows the feeding head 1 to adjust its position according to the height of the receiving bucket 12, and the docking drive mechanism 9 drives the second lifting frame 901 to achieve precise docking between the vertical vibration mechanism and the shaft core 104, ensuring reliable transmission of rotational vibration power and improving the adaptability and automation of the feeding operation.

[0054] In one embodiment, a vertical vibration mechanism 10 is further included, which is mounted on the second lifting frame 901. The vertical vibration mechanism 10 moves up and down with the docking drive mechanism 9 via the second lifting frame 901 to achieve docking and separation with the feed head 1 shaft core 104. The vertical vibration mechanism 10 includes a vertical vibration drive device 1001, a rotating shaft 1002 driven to rotate by the vertical vibration drive device 1001, a lifting rod 1003 circumferentially fixed and axially slidably connected to the rotating shaft 1002, a docking male head 1004 fixed to the lower end of the lifting rod 1003, and a docking male head 1004 fixed to the lifting rod 1003. The upper contact plate 1005 and the contact head 1006 fixed relative to the second lifting frame 901 provide a power source for the rotation and axial vibration of the shaft core 104 via the vertical vibration drive device 1001. The rotating shaft 1002 transmits the torque of the vertical vibration drive device 1001 to the lifting rod 1003. The lifting rod 1003 is circumferentially fixed to the rotating shaft 1002 and axially slidable, capable of transmitting rotational motion and reciprocating up and down along the axial direction. The end face of the contact plate 1005 is provided with a toothed groove, and the contact head 1006 abuts against the toothed groove. 005 rotates synchronously with the lifting rod 1003. The toothed groove on its end face cooperates with the fixed contact head 1006, converting the rotational motion into the periodic axial jump of the lifting rod 1003, forming a vertical vibration excitation. When the second lifting frame 901 descends, the male connector 1004 engages with the docking groove 1042 and presses down the shaft core 104. After the male connector 1004 engages with the docking groove 1042, the shaft core 104 is pressed down, exposing the spiral guide groove 1041 to the outside of the discharge nozzle 101, opening the discharge channel. The vertical vibration drive device 1001 is driven by the rotating shaft 100 2. The lifting rod 1003 and the male connector 1004 are driven to rotate. The male connector 1004 transmits the rotational motion to the shaft core 104, causing the shaft core 104 to rotate and push the powder downward along the spiral guide groove 1041. At the same time, the lifting rod 1003 generates axial vibration through the cooperation of the contact plate 1005 and the contact head 1006, so as to drive the shaft core 104 to rotate synchronously and vibrate axially. The axial vibration is superimposed on the rotational motion, so that the shaft core 104 generates up and down vibration during the feeding process, further breaking the bridging and adhesion of the powder, and improving the uniformity and smoothness of feeding.

[0055] This embodiment achieves a combined drive of rotation and axial vibration of the shaft core 104 through the vertical vibration mechanism 10. The mating of the male connector 1004 and the mating groove 1042 ensures the reliability of power transmission. The toothed groove mating structure of the contact plate 1005 and the contact head 1006 simply converts the rotational motion into axial high-frequency vibration, eliminating the need for an additional vibration generating device. The shaft core 104 generates axial vibration while rotating and feeding, effectively preventing powder from clogging and adhering in the guide chute and discharge nozzle, making the solid powder feeding more continuous and uniform, and significantly improving the feeding accuracy.

[0056] The present invention also provides a solid powder feeding method, which uses the above-mentioned solid powder feeding equipment and includes the following steps: Start the rotary drive mechanism 2 to make the drive disk 3 rotate; the rotary drive mechanism 2 drives the drive disk 3 to rotate, and the drive disk 3, as a unified power distribution component, simultaneously drives the first cam structure 301, the second cam structure 302 and the rotating shaft 303 to achieve the synchronous start of the three functions of vibration, ion wind and receiving cup, ensuring that the feeding process enters the linkage state from the beginning.

[0057] During the rotation of the drive disk 3, the first cam structure 301 strikes the feeding head 1 through the first transmission component 401, and the second cam structure 302 drives the ion air bar 501 to swing through the second transmission component 502. At the same time, the rotating shaft 303 drives the receiving cup 601 away from below the discharge nozzle 101 and limits it through the third transmission component 602. In this step, the first cam structure 301 converts the rotational motion into intermittent striking of the feeding head 1 through the first transmission component 401, causing the feeding head 1 to vibrate laterally, breaking the powder bridging and ensuring smooth feeding. The second cam structure 302 drives the ion air bar 501 to swing through the second transmission component 502, so that the ion air dynamically sweeps the discharge area, eliminates static electricity in the powder, and prevents it from scattering and adhering. The rotating shaft 303 drives the receiving cup 601 to move away from below the discharge nozzle 101 and keep it in a clearance position through the third transmission component 602, making room for the powder to fall and avoiding the receiving cup 601 from interfering with normal feeding.

[0058] Solid powder is fed through the feeding head 1; under the combined action of rotation and axial vibration, the shaft of the feeding head 1 continuously and evenly conveys the solid powder in the housing 102 downward along the spiral guide groove 1041, and the powder falls from the discharge nozzle 101 into the receiving bucket 12 below; during the feeding process, the vibration of the feeding head 1 and the oscillation of the ion wind bar 501 are synchronized to ensure that the powder is always in a loose and electrostatic adsorption-free state, thereby improving the feeding accuracy and uniformity.

[0059] After feeding is completed, the rotating drive mechanism 2 stops rotating, the drive disk 3 stops rotating, and the third transmission component 602 drives the receiving cup 601 to return to below the discharge nozzle 101 to collect any residual powder on the discharge nozzle 101. After the rotating drive mechanism 2 stops rotating, the drive disk 3 loses power, and the reset component in the third transmission component 602 drives the receiving cup 601 to automatically return to below the discharge nozzle 101, collecting any powder that has loosened or remained on the discharge nozzle 101 due to vibration and static electricity, preventing residual powder from falling into the already fed receiving hopper 12, thereby ensuring the accuracy of the final feeding amount.

[0060] This method uses a single rotary drive mechanism 2 to drive an integrated drive disk 3, synchronizing the three key actions—discharge head vibration, ion air purging, and receiving cup avoidance / reset—in time and linking them structurally. The steps are simple, the control logic is clear, and the entire powder feeding process can be automated without complex timing programming. Before feeding, the receiving cup automatically moves away to avoid obstructing the feeding process. During feeding, vibration and ion air work together to ensure smooth powder feeding while eliminating scattering and adhesion caused by static electricity. After feeding, the receiving cup automatically resets to collect residual powder from the discharge nozzle, fundamentally avoiding metering errors caused by residual powder falling into the receiving hopper 12. This method effectively improves the accuracy, stability, and cleanliness of solid powder feeding, and is particularly suitable for the precise addition of trace amounts, valuable, or toxic and harmful powders in laboratory environments.

[0061] This invention also provides an ion fan mechanism for a solid powder feeding device, used to destaticate a vibrating feeding head 1. A receiving hopper 12 is located below the feeding head 1, and two ion fan bars 501 are provided. The two ion fan bars 501 are respectively disposed on both sides of the feeding port of the feeding head 1. The two ion fan bars 501, arranged on both sides of the feeding port of the feeding head 1, simultaneously blow ion air into the discharge area from two directions, forming a symmetrical destatic airflow that covers both sides of the powder's falling path, eliminating static dead zones that may exist due to unilateral blowing. Each ion fan bar 501 is hinged to a fixed bracket or the side wall of the feeding head 1 via a mounting plate 503, allowing the two ion fan bars 501 to swing around their respective hinge axes. The mounting plate 503 serves as the swing support for the ion fan bars 501. The body, through a hinge, allows the ion air bar 501 to swing within a certain angle range around the hinge axis, thereby adjusting the jet direction of the ion airflow and dynamically sweeping the discharge nozzle area, expanding the coverage and uniformity of the ion airflow. The air outlet of the ion air bar 501 faces the discharge nozzle area of ​​the feeding head 1, and is used to blow ion air onto the powder material falling from the discharge nozzle. The air outlet is aligned with the discharge nozzle area, so that the ion air directly acts on the powder material falling from the discharge nozzle and the area near the outer wall of the discharge nozzle, effectively neutralizing the static electricity generated by friction during the powder's fall, and reducing the static adsorption and scattering of powder at the discharge nozzle and the edge of the receiving hopper 12. The two ion air bars 501 are configured to swing synchronously or asynchronously during the vibration feeding process of the feeding head 1 to change the coverage of the ion airflow. The two ion air bars 501 can swing synchronously or asynchronously. By swinging, the spray angle and coverage area of ​​the ion airflow are changed, so that the ion airflow forms a dynamically changing antistatic airflow field around the discharge nozzle. This better adapts to the changes in the powder falling trajectory during the vibrating feeding process of the feeding head 1, ensuring that the powder is always affected by the ion airflow throughout the entire falling process.

[0062] The ion fan mechanism of the present invention has the following advantages compared with the prior art: Two ion air bars symmetrically positioned on either side of the feed head's discharge port create a double-sided enveloping ion airflow. Combined with a hinged oscillating structure, this dynamically sweeps the discharge area, effectively eliminating static electricity during powder descent, reducing powder scattering and adhesion, and improving feeding accuracy and cleanliness. Simultaneously, the oscillation of the ion air bars synchronizes with the vibrating feed head's feeding action, adapting to dynamic changes in the powder's trajectory and ensuring stable and reliable static elimination throughout the feeding process. This device can be used independently in various vibrating feeding systems or integrated with the aforementioned solid powder feeding equipment; it features a compact structure and high adaptability.

[0063] The ion fan mechanism can be used independently or in combination with the solid powder feeding equipment described in any of the above embodiments. When used independently, the ion fan bar 501 can be oscillated by an external drive source to remove static electricity from any feeding head with vibration feeding function. When used in combination with the solid powder feeding equipment, the oscillation of the ion fan bar 501 is synchronously driven by the second cam structure 302 of the drive disk 3 through the second transmission component 502, so that the oscillation of the ion fan bar 501 is linked with the vibration and impact of the feeding head 1 and the avoidance and reset action of the receiving cup 601. There is no need to set a separate drive source for the ion fan bar 501, which simplifies the overall structure and ensures the synchronization of the actions.

[0064] In one embodiment, the system further includes a rotary drive mechanism 2 and a drive disk 3. The drive disk 3 is driven to rotate by the rotary drive mechanism 2, and a second cam structure 302 is provided on the outer peripheral surface of the drive disk 3. The two ion air bars 501 are respectively connected to the second cam structure 302 through a transmission assembly, so as to drive the two ion air bars 501 to swing when the drive disk 3 rotates. In one embodiment, the transmission assembly includes a guide rod 5021 and a sliding frame 5022. One end of the guide rod 5021 is slidably engaged in the second cam structure 302, and the other end is fixedly connected to the sliding frame 5022. The sliding frame 5022 is slidably arranged in the vertical direction. In one embodiment, the transmission assembly further includes a connecting finger 5023 and a connecting frame 5024. One end of the connecting finger 5023 is fixedly connected to the sliding frame 5022, and the other end is slidably engaged with the connecting frame 5024. The connecting frame 5024 is fixedly connected to the mounting plate 503. In one embodiment, the connecting frame 5024 has a groove, and the other end of the connecting finger 5023 slides within the groove. When the sliding frame 5022 reciprocates up and down, the connecting finger 5023 pushes the connecting frame 5024, causing the mounting plate 503 to swing around its hinge axis. In one embodiment, two ion air bars 501 are symmetrically arranged on both sides of the feed inlet of the feeding head 1. The two ion air bars 501 are respectively connected to the same second cam structure 302 through two sets of transmission components, and the guide rods 5021 of the two sets of transmission components are integrally connected to make the two ion air bars 501 swing synchronously. In one embodiment, the rotary drive mechanism 2 is also used to drive the vibration mechanism of the feeding head 1 so that the swing of the ion air bars 501 is synchronized with the vibration feeding action of the feeding head 1.

[0065] The specific structure, transmission relationship and beneficial effects of the above embodiments are the same as the corresponding parts in the aforementioned solid powder feeding equipment, and will not be repeated here.

[0066] In one embodiment, a support arm 504 is also included. One end of the support arm 504 is fixedly disposed, specifically integrally formed or fixedly connected to the equipment frame (specifically, the first lifting frame 801), and the other end is hinged to the mounting plate 503. The support arm 504 provides a fixed hinge fulcrum for the mounting plate 503, allowing the mounting plate 503 to swing stably around the hinge point. The mounting plate 503 is hinged to the side of the feeding head 1 or the fixed bracket via the support arm 504. The support arm 504 reliably supports the mounting plate 503 on the side of the feeding head 1 or the equipment fixed bracket, ensuring that the ion air bar 501 has a defined motion trajectory and sufficient support rigidity during swinging. In addition, the sliding frame 5022 is slidably disposed on the support arm 504, with the support arm 504 providing sliding guidance.

[0067] This embodiment provides a stable hinged support for the mounting plate 503 and the ion air bar 501 by setting a support arm 504, which makes the swinging action of the ion air bar 501 more stable and reliable, avoiding swing deviation or shaking caused by insufficient rigidity of the installation structure, thereby ensuring that the ion air always acts accurately on the discharge area, improving the static elimination effect and the working stability of the device.

[0068] In one embodiment, a limiting structure 505 is provided between the mounting plate 503 and the support arm 504. The limiting structure 505 is used to limit the swing angle range of the mounting plate 503, ensuring that the air outlet of the ion air bar 501 always faces the discharge nozzle area of ​​the feeding head 1. The limiting structure 505 mechanically constrains the swing amplitude of the mounting plate 503, preventing the swing angle from being too large and causing the air outlet of the ion air bar 501 to deviate from the discharge nozzle area, ensuring that the ion air always effectively acts on the powder falling path and the outer wall of the discharge nozzle; at the same time, the limiting structure 505 also avoids collision interference between the mounting plate 503 and surrounding components, improving the operational safety and reliability of the device.

[0069] This embodiment limits the swing range of the mounting plate 503 and the ion fan bar 501 to a reasonable angle by setting a limiting structure 505, ensuring that the air outlet of the ion fan bar 501 is always aligned with the discharge nozzle area of ​​the feeding head 1 during the swing process, so that the ion wind continuously covers the powder falling path and the static elimination effect is stable; at the same time, the limiting structure prevents component damage and airflow direction deviation caused by swing overtravel, further improving the working stability and service life of the ion fan mechanism.

[0070] The present invention also provides a solid powder feeding device, including the above-described ion fan mechanism. This solid powder feeding device can be any of the solid powder feeding devices described in the above embodiments, or other existing solid powder feeding devices; that is, the ion fan mechanism can be independently configured on any feeding head with vibration feeding function, and is not limited to the specific equipment structure described above, thus improving the versatility and applicability of the ion fan mechanism.

[0071] The present invention also provides a feeding head mounting structure for detachably mounting the feeding head 1 onto the mounting frame 802 of a solid powder feeding device, comprising: The support rod 106 is fixed on the mounting frame 802, and the support rod 106 has a locking groove 1061. The support rod 106 serves as the installation positioning reference for the feeding head 1 and is fixed on the mounting frame 802. The locking groove 1061 cooperates with the locking frame 107 to lock and fix the feeding head 1, preventing the feeding head 1 from loosening under vibration conditions.

[0072] The housing 102 of the feeding head 1 has a fixing hole 1021 that mates with the support rod 106. The side wall of the housing 102 has a clamping groove 1022 and a clearance groove 1023. The fixing hole 1021 is used to fit onto the support rod 106 to achieve the installation and positioning of the feeding head 1. The clamping groove 1022 provides a clamping position for the clamping arm 1101 of the electric gripper 11. The clearance groove 1023 provides movement space for the locking frame 107 and the pressing protrusion 1102 to avoid structural interference.

[0073] A locking frame 107 is rotatably connected to the housing 102. At least a portion of the locking frame 107 is located within the recessed groove 1023. One end of the locking frame 107 is a head 1071, and the other end is a tail 1072. A second torsion spring 108 is provided between the locking frame 107 and the housing 102. The second torsion spring 108 is used to drive the head 1071 of the locking frame 107 to engage in the locking groove 1061, thereby locking the feeding head 1. Under the elastic force of the second torsion spring 108, the head 1071 of the locking frame 107 automatically engages in the locking groove 1061, so that the feeding head 1 remains locked when there is no external force, preventing the feeding head 1 from accidentally falling off.

[0074] The electric gripper 11 has two clamping arms 1101 that can open and close relative to each other, and each clamping arm 1101 is provided with a pressing protrusion 1102. The electric gripper 11 is used to clamp the feeding head 1 for installation or disassembly operations. The pressing protrusion 1102 is used to squeeze the tail 1072 of the locking frame 107 during clamping, driving the locking frame 107 to rotate and unlock.

[0075] When the electric gripper 11 grips the feeding head 1, the two gripping arms 1101 respectively engage with the gripping grooves 1022, and the pressing protrusion 1102 enters the clearance groove 1023 and presses the tail 1072 of the locking frame 107, causing the locking frame 107 to rotate against the elastic force of the second torsion spring 108, and the head 1071 disengages from the locking groove 1061, thus unlocking. When the electric gripper 11 is released, the second torsion spring 108 drives the locking frame 107 to reset, and the head 1071 re-engages with the locking groove 1061, thus locking. Through the gripping and releasing of the electric gripper 11, combined with the linkage of the locking frame 107 and the second torsion spring 108, the automatic switching between the unlocking and locking actions of the feeding head 1 is achieved, making the disassembly and assembly of the feeding head 1 fast, accurate, and reliable.

[0076] The feeding head mounting structure provided by this invention has the following advantages compared to the prior art: 1. The electric gripper 11 is used to simultaneously unlock the device, eliminating the need for manual twisting or disassembly of tools. This enables rapid replacement of the feeding head 1, significantly shortening the replacement time and adapting to the continuous operation requirements of automated production lines.

[0077] 2. The second torsion spring 108 drives the head 1071 of the locking frame 107 to engage in the locking groove 1061 of the support rod 106, forming a rigid engagement. The locking state is stable and will not loosen due to vibration or impact during equipment operation, thus ensuring the installation stability of the feeding head 1 during the feeding process.

[0078] 3. Since the solid powder feeding equipment needs to apply lateral impact vibration to the feeding head 1 during the feeding process, the traditional threaded connection is prone to loosening under continuous vibration. However, this structure effectively resists the vibration through the locking frame 107 and the locking groove 1061, ensuring that the relative position between the feeding head 1 and the mounting frame 802 remains unchanged, thereby ensuring the alignment accuracy between the discharge nozzle 101 and the receiving container.

[0079] 4. It uses only simple structural components such as support rod 106, locking frame 107, second torsion spring 108 and clamping groove 1022, without the need for additional power source or complex control, resulting in low manufacturing cost and convenient assembly and maintenance.

[0080] 5. This installation structure can be adapted to different specifications of feeding heads 1. As long as the matching dimensions of the fixing hole 1021 and the locking frame 107 are standardized, it can be applied to different models of solid powder feeding equipment, which is convenient for upgrading and retrofitting existing equipment. In terms of safety, the reliable locking avoids powder leakage or equipment damage caused by the feeding head 1 accidentally falling off during vibration. It is especially suitable for feeding scenarios of toxic, harmful or valuable powders, protecting the safety of operators.

[0081] 6. The feeding head 1 is installed in a stable and consistent position, ensuring that the relative position of the discharge nozzle 101 and the receiving container remains unchanged each time material is fed, which helps to improve the accuracy and repeatability of the feeding amount.

[0082] In one embodiment, four locking frames 107 are provided, and the four locking frames 107 are symmetrically rotatably connected to both sides of the housing 102 in pairs. The four locking frames 107 correspond to the four support rods 106 respectively, forming a four-point symmetrical locking layout, so that the locking force of the feeding head 1 on the mounting frame 802 is evenly distributed, avoiding unilateral force or uneven load. The head 1071 of each locking frame 107 cooperates with the locking groove 1061 of one of the support rods 106. Each locking frame 107 independently snaps into the locking groove 1061 of the corresponding support rod 106, realizing multi-point synchronous locking. Even if one locking frame 107 is subjected to vibration impact, the other locking frames 107 can still maintain the locked state, which significantly improves the installation reliability of the feeding head 1 under vibration conditions.

[0083] This embodiment uses four symmetrically distributed locking frames 107, which correspond one-to-one with four support rods 106 to form a four-point locking system. This makes the feeding head 1 more securely fixed on the mounting frame 802, with balanced force distribution, preventing the feeding head 1 from tilting or shifting due to vibration, and ensuring the alignment accuracy between the discharge nozzle 101 and the receiving container. At the same time, the multi-point locking structure has redundancy. If a single locking frame 107 fails unexpectedly, the remaining locking frames 107 can still maintain the lock, making the equipment safer to operate. In addition, the layout of the four locking frames 107 makes full use of the space on both sides of the feeding head 1 housing 102, with a compact structure that does not increase the external dimensions, making it easy to achieve reliable feeding head fixing within a limited equipment space.

[0084] In one embodiment, the locking frame 107 includes a head straight portion 107a and a tail straight portion 107b that are parallel to each other, and an inclined connecting portion 107c connecting the head straight portion 107a and the tail straight portion 107b. The locking frame 107 is rotatably connected to the housing 102 via a connecting shaft 109, which is disposed on the inclined connecting portion 107c. The head straight portion 107a is located on the outer side, and the tail straight portion 107b is located on the inner side. The head straight section 107a and the tail straight section 107b are arranged parallel to each other and staggered front to back. The inclined connecting section 107c serves as an intermediate transition section, connecting the two into one unit, so that the locking frame 107 as a whole forms a Z-shaped or stepped lever structure. The connecting shaft 109 is set on the inclined connecting section 107c, so that the head straight section 107a and the tail straight section 107b are located on both sides of the connecting shaft 109, forming two lever arms. The head straight section 107a is located on the outside and is used to engage the support rod from the outside direction. Locking is achieved within the locking groove 1061 of 106. The straight section 107b at the tail is located on the inner side and is used to receive the squeezing force applied from the inner side by the pressing protrusion 1102, so that the straight section 107a at the head can swing outward around the connecting pivot 109 to disengage from the locking groove 1061 and complete the unlocking action. This layout allows the locking frame 107 to be reasonably arranged within the limited space of the clearance groove 1023, with clear division of labor between the head and tail, and the force direction and movement direction coordinated, avoiding interference with the housing 102 or support rod 106 during the unlocking process.

[0085] In one embodiment, the end of the support rod 106 is provided with a guide surface 1062, and the fixing hole 1021 is a through hole that matches the cross-section of the support rod 106; The locking groove 1061 is a groove arranged circumferentially along the support rod 106. The guide surface 1062 at the end of the support rod 106 plays a guiding role during the installation of the feeding head 1, so that the fixing hole 1021 can be quickly and accurately aligned and fitted into the support rod 106, reducing the difficulty of installation alignment and improving assembly efficiency; the fixing hole 1021 matches the cross section of the support rod 106, so that the radial position of the feeding head 1 is constrained after it is fitted, preventing the feeding head 1 from radially shaking or shifting relative to the support rod 106; the locking groove 1061 is arranged circumferentially along the support rod 106, so that the head 1071 of the locking frame 107 can be inserted into the locking groove 1061 from any circumferential position without the need for precise circumferential positioning, further reducing the installation difficulty. At the same time, the circumferential groove structure makes the locking frame 107 more stable and has a strong resistance to axial disengagement.

[0086] In one embodiment, the clamping groove 1022 is located inside the clearance groove 1023, and the opening of the clamping groove 1022 faces the outside of the housing 102. The clamping groove 1022 is located inside the avoidance groove 1023, so that after the clamping arm 1101 of the electric gripper 11 is inserted into the clamping groove 1022, the outer surface of the clamping arm 1101 can not exceed the outer surface of the corresponding side wall of the housing 102, or minimize the protrusion, maintain the compactness of the overall shape of the feeding head 1, and avoid interference with surrounding components during the lifting or replacement of the feeding head 1; at the same time, the opening of the clamping groove 1022 faces the outside of the housing 102, which makes it easy for the electric gripper 11 to be directly inserted into the clamping groove 1022 from both sides of the feeding head 1, and the clamping action is smooth. The pressing protrusion 1102 can naturally enter the avoidance groove 1023 located inside the clamping groove 1022 as the clamping arm 1101 is inserted, so as to achieve precise pressing of the tail 1072 of the locking frame 107.

[0087] In one embodiment, the pressing protrusion 1102 has an inclined surface 11021 toward the tail 1072 of the locking frame 107, the inclined surface 11021 being used to gradually press the tail 1072 of the locking frame 107 when the electric gripper 11 is closed, so that its head 1071 smoothly disengages from the locking groove 1061. The inclined surface 11021 on the pressing protrusion 1102 serves as the unlocking drive surface. During the closing process of the electric gripper 11, it contacts the tail 1072 of the locking frame 107, converting the linear closing motion of the gripping arm 1101 into a gradual compression of the tail 1072 of the locking frame 107. The inclination angle of the inclined surface 11021 allows the compressive force to be applied smoothly along the rotation direction of the locking frame 107, avoiding instantaneous impact. Under the push of the inclined surface 11021, the locking frame 107 gradually rotates around the connecting shaft 109, and the head 1071 smoothly exits from the locking groove 1061, achieving smooth unlocking and reducing mechanical impact on the locking frame 107, the second torsion spring 108, and the locking groove 1061 of the support rod 106.

[0088] The present invention also provides a feeding head, including the above-described feeding head mounting structure. The feeding head 1 further includes a top cover 103, a shaft core 104, and a second elastic element 105. The top cover 103 is fixed to the top of the housing 102 and closes the top opening of the housing 102, providing mounting support and axial limiting reference for the shaft core 104. The shaft core 104 is rotatably and axially slidably inserted into the housing 102. As the core discharge control component of the feeding head 1, the shaft core 104 controls the discharge and closing of powder through rotation and axial sliding movements. The lower part of the shaft core 104 is provided with a spiral guide groove 1041. When the shaft core 104 rotates, the spiral guide groove 1041 pushes the solid powder in the housing 102 downward along the groove, so that the powder is continuously and uniformly transported. The material is discharged from the discharge nozzle 101; the top of the shaft core 104 is provided with a docking groove 1042, which is used to engage with the docking male head 1004 of the vertical vibration mechanism 10, and transmit rotational power and axial vibration to the shaft core 104 at the same time; the second elastic member 105 is disposed between the shaft core 104 and the top cover 103, which is used to make the shaft core 104 have an upward reset tendency. In the non-feeding state, the second elastic member 105 pushes the shaft core 104 back to the upper closed position, so that the spiral guide groove 1041 is stored inside the housing 102, sealing the discharge channel and preventing powder leakage; when feeding, the vertical vibration mechanism 10 presses down the shaft core 104 and compresses the second elastic member 105, so that the spiral guide groove 1041 is exposed to the outside of the discharge nozzle 101, realizing the discharge.

[0089] This embodiment achieves the normal closure of the discharge channel of the feeding head 1 and the controllable opening during feeding through the cooperation of the top cover 103, the shaft core 104, and the second elastic element 105. The structure is compact and the operation is reliable. The reset force provided by the second elastic element 105 enables the shaft core 104 to automatically close the discharge channel when there is no external force, effectively preventing powder leakage when not feeding. The spiral guide groove 1041, in conjunction with the rotational motion of the shaft core 104, realizes the active conveying of powder, with good uniformity and continuity of discharge, which is conducive to improving the feeding accuracy. The setting of the docking groove 1042 enables the shaft core 104 to quickly dock with the docking male head 1004 of the vertical vibration mechanism 10. The power transmission path is short and the alignment is accurate, providing a reliable interface for the combined feeding of rotation and axial vibration.

[0090] In one embodiment, a material feeding frame 1010 is further included. The material feeding frame 1010 is sleeved on the outside of the shaft core 104 and can rotate relative to the shaft core 104 about its axis. The material feeding frame 1010 and the shaft core 104 are connected by a clearance fit or a rotatable connection, so that the material feeding frame 1010 does not rotate synchronously with the shaft core 104, but can generate relative rotation by inertia or gravity when the shaft core 104 rotates, thereby creating a stirring effect on the powder inside the housing 102. The material feeding frame 1010 is provided with a counterweight structure 10101, which makes the material feeding frame... The center of gravity of 1010 is lower than the mating part with the shaft core 104. Under the action of gravity, the lower end of the material feeding frame 1010 is kept in the lower region of the inner cavity of the housing 102. The counterweight structure 10101 uses gravity to keep the lower end of the material feeding frame 1010 always located in the lower part of the inner cavity of the housing 102, that is, the area where powder is easy to accumulate and bridge, to ensure that the turning plate of the material feeding frame 1010 always acts on the part where the powder is most concentrated, thereby improving the turning effect. The bottom of the material feeding frame 1010 is provided with an arc-shaped turning plate 10102 for turning the powder in the housing 102. The arc-shaped turning plate 10102 conforms to the arc-shaped contour of the bottom of the housing 102 or the inner wall of the discharge nozzle 101. As the material feeding frame 1010 swings or rotates, it continuously turns over in the powder accumulation area, destroying the bridging and arching structure of the powder, keeping the powder in a loose state, promoting the powder to be fed into the spiral guide groove 1041 of the shaft core 104, and ensuring continuous and uniform feeding.

[0091] This embodiment adds a relatively rotatable material feeding frame 1010 to the outside of the shaft core 104, and uses a counterweight structure 10101 to ensure that the tipping blade of the material feeding frame 1010 always acts on the powder accumulation area below the inner cavity of the housing 102. In conjunction with the rotational movement of the shaft core 104, it achieves continuous agitation of the powder, effectively preventing powder from bridging and clogging inside the feeding head 1, and improving the smoothness and uniformity of feeding. The material feeding frame 1010 does not require an additional drive source, and only relies on the friction or inertia between the shaft core 104 and the powder to generate relative movement. It has a simple structure and low energy consumption. In addition, the arc-shaped tipping blade 10102 fits against the inner wall of the discharge nozzle 101, which can clean the inner wall at the same time, reduce powder adhesion, and help improve feeding accuracy and equipment cleanliness.

[0092] In one embodiment, the bottom of the housing 102 is provided with the discharge nozzle 101, and a discharge channel is formed between the lower end of the shaft core 104 and the inner wall of the discharge nozzle 101. The discharge nozzle 101 serves as the channel through which the powder finally leaves the feeding head 1. The annular gap between the lower end of the shaft core 104 and the inner wall of the discharge nozzle 101 forms the discharge channel, through which the powder is discharged downward from the inner cavity of the housing 102. The size and shape of the channel directly affect the discharge flow rate and accuracy. When the shaft core 104 is pressed down, the spiral guide groove 1041 is at least partially exposed outside the discharge nozzle 101. After the shaft core 104 is pressed down, the spiral guide groove 1041 extends out from the discharge nozzle 101, opening the discharge channel, allowing the powder to enter the spiral guide groove 1041 and be conveyed downward with the rotational motion. When the shaft core 104 is not pressed down, the spiral guide groove 1041 retracts into the housing 102. The discharge channel is closed to prevent leakage. The rotation of the shaft core 104 causes the powder to be conveyed downward along the spiral guide groove 1041. The spiral guide groove 1041 cooperates with the inner wall of the discharge nozzle 101, forming a spiral conveyor-like function when rotating. The powder is continuously pushed downward by the spiral groove, and the discharge process is continuous, uniform and controllable, avoiding the discontinuity or impact caused by the free fall of powder. The arc-shaped turning plate 10102 of the material feeding frame 1010 fits against the inner wall of the discharge nozzle 101 or the inner wall of the housing 102. The arc-shaped contour of the turning plate 10102 is adapted to the curved shape of the inner wall of the discharge nozzle 101 or the inner wall of the housing 102, so that the turning plate is always close to the inner wall when it moves with the material feeding frame 1010. It can both turn the powder to prevent bridging and scrape off the powder adhering to the inner wall during the movement, keeping the inner wall of the discharge channel clean and reducing the risk of powder residue and blockage.

[0093] This invention also provides a solid powder feeding device, including the aforementioned feeding head mounting structure.
