Description

Technical Field

[0001] This invention relates to the field of carbon black production and packaging equipment technology, specifically to a coarse and fine feeding combined vibration anti-caking carbon black ton bag packaging equipment. Background Technology

[0002] Carbon black is an indispensable core raw material in the rubber industry. With its excellent reinforcing, abrasion-resistant, and coloring properties, it is widely used in many industries such as tires, rubber products, and plastic products, with tire processing being the primary application scenario. In the industrial production process of carbon black, the finished carbon black granules, after granulation, drying, and screening, need to be quantitatively packaged using ton bag packaging equipment for easy storage, transportation, and subsequent use.

[0003] The current carbon black ton bag packaging equipment has an overall structure consisting of a material distribution device, a feeding device, an electronic weighing device, and a bag clamping device arranged from top to bottom. The core working logic is that the carbon black material in the storage hopper is diverted by the material distribution device, then fed out by the feeding device, and the weight of the material is monitored in real time by the electronic weighing device. Once the set weight is reached, the feeding stops, and finally the ton bag is fixed by the bag clamping device to complete the sealing operation.

[0004] However, in long-term practical production applications, existing ton bag packaging equipment suffers from a lack of material feeding stability and weighing accuracy. Carbon black granules have the physical characteristics of small particle size, light texture, and easy adsorption and agglomeration. Under the influence of factors such as self-weight accumulation, material compression, and slightly humid environment, carbon black material in the storage hopper is very prone to accumulation, bridging, and clumping at the bottom of the storage hopper and the feeding end of the distribution device. Conventional equipment relies solely on the material's own weight to complete the feeding, without active arch breaking or anti-caking structures. The agglomerated carbon black material will block the distribution channel, resulting in intermittent feeding, fluctuating flow rates, and an inability to achieve uniform and stable feeding.

[0005] The aforementioned material feeding issues directly lead to the following problems: First, clumped material blocking the material channel will cause feeding jams and interruptions, significantly reducing the continuity of packaging operations; Second, uneven material flow will seriously interfere with the detection accuracy of the electronic weighing device, resulting in weighing deviations, exceeding tolerances, and underweighting, leading to substandard finished product packaging weight and an increased defect rate; Third, carbon black lumps entering the packaging bag without being broken up will cause uneven material density inside the ton bag, affecting not only the neatness of the packaging. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a coarse and fine feeding combined vibration anti-caking carbon black ton bag packaging equipment. Through the linkage vibration structure of coarse and fine feeding, vibration anti-caking and arch breaking of the corresponding material channels are realized in the coarse feeding and fine feeding stages, respectively. The feeding is uniform and stable, which greatly improves the accuracy of electronic weighing and packaging quality, so as to solve the problems of easy agglomeration, uneven feeding, poor linkage between coarse and fine feeding, and low weighing accuracy in the existing carbon black ton bag packaging equipment.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A coarse and fine feeding combined vibration anti-caking carbon black ton bag packaging equipment is provided, which is connected from top to bottom to a material distribution device, a feeding device, an electronic weighing device, and a bag clamping device. The material distribution device includes a coarse feeding device and a fine feeding device. The core improvement is that an electromagnetic vibrator is installed on the side of the coarse feeding device. When the coarse feeding device is in the coarse feeding stage, the electromagnetic vibrator directly transmits vibration to the conveying channel inside the coarse feeding device. A vibration transmission device that can be linked to the conveying channel inside the fine feeding device is also installed on the conveying channel inside the coarse feeding device. When the fine feeding device is in the fine feeding stage, the electromagnetic vibrator indirectly transmits vibration to the conveying channel inside the fine feeding device through the vibration transmission device.

[0008] By adopting the above scheme, the equipment features a two-stage coarse and fine feeding linkage vibration structure, which differs from the traditional single-weight feeding structure without vibration anti-clogging. In the coarse feeding stage, the electromagnetic vibrator directly drives the coarse feeding conveyor to vibrate, which can break up the large-volume carbon black agglomerates accumulated and clumps in the coarse feeding channel in real time, eliminate material bridging, and ensure a large flow rate and continuous stable feeding in the coarse feeding stage, avoiding problems such as jamming, material interruption, and flow fluctuation in coarse feeding. In the fine feeding stage, the vibration energy of the electromagnetic vibrator is linked and transmitted through a vibration transmission device, which indirectly drives the fine feeding conveyor to vibrate, breaking up small carbon black clumps and suspended agglomerates in the fine feeding channel, ensuring the uniformity of small flow rate fine feeding, and fundamentally solving the problems of carbon black feeding blockage and unstable flow. This provides a stable material conveying foundation for the accurate metering of electronic weighing devices and significantly reduces weighing errors.

[0009] As a preferred embodiment of a coarse and fine feeding combined vibration anti-caking carbon black ton bag packaging equipment, the material distribution device includes a left distribution channel and a right distribution channel arranged sequentially on the left and right sides. The top openings of the left and right distribution channels are integrated, while their bottom openings are separate. By adopting a dual-channel structure with separate top and independent bottom, the integrated top opening can uniformly receive carbon black material falling from the storage hopper, achieving centralized material diversion and avoiding material spillage and waste. The separate bottom opening allows the left and right distribution channels to independently correspond to the coarse and fine feeding devices, enabling independent material conveying without interference. Simultaneously, this structure can accurately distinguish between the coarse and fine feed material flows, avoiding the problems of disordered feed flow and clumping caused by the mixing of coarse and fine materials. It also improves the overall structural stability of the material distribution device, providing structural support for the stable operation of subsequent graded vibration and graded feeding.

[0010] As a preferred embodiment of a coarse and fine feeding combined vibration anti-caking carbon black ton bag packaging equipment, the coarse feeding device includes a feeder box, a horizontally inclined coarse conveying channel is provided on the right side of the feeder box, and a coarse baffle plate is provided inside the feeder box near the outlet of the coarse conveying channel and conveying the material downward; wherein, an electromagnetic vibrator is fixed to the bottom side of the coarse conveying channel and can vibrate under the action of the electromagnetic vibrator. The horizontally inclined coarse conveying channel is adapted to the high-flow, rapid material discharge requirements of the coarse feeding stage. The inclined structure enables gravity-flow material transport, improving coarse feeding efficiency. An electromagnetic vibrator fixed to the bottom side can transmit vibration energy efficiently and at close range, ensuring uniform vibration throughout the coarse conveying channel without dead zones, thoroughly breaking up accumulated carbon black clumps. An internal coarse baffle guides and limits the flow of coarse material, preventing splashing and deviation during high-flow material discharge, and constraining the material to flow vertically downwards, ensuring a stable material transport trajectory. This structure optimizes the coarse feeding path and vibration effect, effectively solving problems such as material accumulation, clumping, and skewing during high-flow coarse feeding, ensuring a stable, efficient, and continuous discharge flow during the coarse feeding stage.

[0011] As a preferred embodiment of a coarse and fine feeding combined vibration anti-caking carbon black ton bag packaging equipment, the fine feeding device includes a fine conveying channel installed inside the feeder box and connected to the left distribution channel. A fine feeding arc gate is installed at the bottom of the fine conveying channel. The fine feeding arc gate can swing left and right under the drive of a swing drive assembly outside the feeder box. When the fine feeding arc gate swings, it can open or close the outlet at the bottom of the fine conveying channel. A sealing baffle fixed on the fine conveying channel is provided at the outlet. The built-in precision conveying channel has a compact structure and can be precisely connected to the left-side distribution channel to achieve stable storage and conveying of precision materials. The precision feeding arc gate is driven to swing left and right by the swing drive assembly, which can precisely control the opening and closing amplitude and speed of the precision material channel outlet, realizing fine-tuned feeding with small flow and high precision, and adapting to the needs of precise replenishment in the later stage of weighing. The sealing baffle at the outlet can achieve flexible sealing during the opening and closing of the arc gate, preventing the leakage of fine carbon black dust during the precision feeding stage, and avoiding the problem of incomplete closure and material leakage caused by dust stuck in the arc gate gaps. This ensures precise start and stop of feeding and no material leakage during the precision feeding stage, and further improves the accuracy of weighing and measurement.

[0012] As a preferred embodiment of a coarse and fine feeding combined vibration anti-caking carbon black ton bag packaging equipment, the swing drive assembly includes a horizontally arranged swing cylinder. A straight arm is coaxially connected to the telescopic section of the swing cylinder. At the end of the straight arm, a rocker arm is rotatably mounted via a rotating arm, extending through to the top of the feeder housing. The fine feeding arc gate is fixedly connected to the rocker arm and swings left and right around the rocker arm. The cylinder + connecting rod rocker drive structure ensures precise transmission, stable operation, and fast response. The horizontal telescopic movement of the swing cylinder drives the straight arm and rotating arm in linkage, thereby driving the rocker arm to swing precisely, achieving smooth opening and closing of the fine feeding arc gate. This transmission structure has small transmission gaps and high operational precision, allowing for precise control of the arc gate's swing angle, thus accurately adjusting the flow cross-sectional area of ​​the fine feeding and achieving refined control of the feeding flow rate.

[0013] As a preferred embodiment of a coarse and fine feeding combined vibration anti-caking carbon black ton bag packaging equipment, the left side of the feeder box is connected to an upwardly extending dust collection nozzle, which can be directly connected to external dust collection equipment to accurately collect the fine carbon black dust generated during the feeding process inside the feeder box. Dust is easily generated during the vibration of carbon black material feeding; the dust collection nozzle can promptly extract suspended dust from the box, preventing dust accumulation in the fine conveying channel and the arc gate transmission structure, thus preventing dust agglomeration and blockage of the channel and transmission components.

[0014] As a preferred embodiment of a coarse and fine feeding combined vibration anti-caking ton bag packaging equipment for carbon black, the vibration transmission device includes a vibrating seat fixed to the top of the coarse conveying channel and extending into the feeder housing. Multiple vibrating supports aligned in a straight line are fixedly connected to the vibrating seat. Each vibrating support has a notch at its top that contacts the rocker arm wall. Vertically arranged vibrating guide rods are also provided at the front and rear sides of the coarse conveying channel. Vibrating side ears, capable of moving up and down along the vibrating guide rods, are connected to the front and rear sides of the coarse conveying channel. A push spring is fitted onto the vibrating guide rod to continuously push the vibrating side ears upwards. All the notches of the vibrating supports can contact the rocker arm wall under the elastic action of the push spring. This mechanical vibration transmission device design enables precise and stable linkage transmission of the vibration energy of the electromagnetic vibrator. The elastic thrust of the push spring continuously pushes the vibrating side ear, ensuring that the top cut of the vibrating support always fits against the rocker arm wall, thus constructing a stable vibration transmission path. The vibration energy of the coarse conveying channel is transmitted to the fine feeding arc gate and the fine conveying channel through the vibrating seat, vibrating support, and rocker arm, achieving synchronous vibration and anti-caking of the fine material channel. The vibrating guide rod, in conjunction with the vibrating side ear, can limit the up and down movement trajectory of the coarse conveying channel, ensuring the stability of the structure and avoiding deviation and jamming. Multiple sets of coaxially arranged vibrating supports can evenly distribute the vibration energy, ensuring uniform force across the entire rocker arm, guaranteeing uniform vibration of the fine material channel without dead angles, and solving the problem of agglomeration and clumping of fine carbon black during the fine feeding stage.

[0015] As a preferred embodiment of a coarse and fine feeding combined vibration anti-caking carbon black ton bag packaging equipment, the cut has a triangular cross-sectional shape, which has the advantages of sharp corner guidance, good fit and high wear resistance. It can form a precise line contact fit with the cylindrical rocker arm wall, with precise contact position and concentrated force, which can maximize the transmission of vibration energy and reduce vibration transmission loss.

[0016] As a preferred embodiment of a coarse and fine feeding combined vibration anti-caking carbon black ton bag packaging equipment, the inlet and outlet of the coarse conveying channel are sequentially and movably connected to the right distribution channel and the feeder box, and the entire coarse conveying channel can move up and down; when the coarse feeding device is in the coarse feeding stage, the material will press down on the coarse conveying channel, thereby driving all the vibration supports and rockers to separate up and down; when the fine feeding device is in the fine feeding stage, the coarse conveying channel will move upward to reset because there is no material pressing down, and under the action of the push spring, all the vibration supports and rockers will contact up and down. The design of the coarse conveying channel allows for vertical floating, enabling automatic switching of vibration modes between the coarse and fine feeding stages. This requires no electrical intervention, relying solely on mechanical self-adaptation for precise and zero-delay response. During the coarse feeding stage, the material's gravity presses down on the coarse conveying channel, separating the vibrating support from the rocker arm. Vibration energy is focused solely on the coarse conveying channel, effectively breaking up large clumps and preventing energy dispersion, thus ensuring effective anti-bridging and anti-blocking during coarse feeding. During the fine feeding stage, with no material pressing down on the coarse channel, a push spring drives the channel to reset, the vibrating support engages with the rocker arm, and vibration energy is transmitted to the fine feeding channel, specifically preventing clumping during fine feeding.

[0017] As a preferred implementation of a combined coarse and fine feeding vibration anti-caking ton bag packaging equipment for carbon black, when the coarse feeding device is in the coarse feeding stage, the fine feeding gate of the fine feeding device is normally closed. At this time, the fine conveying channel of the entire fine feeding device is completely filled with material, and the coarse conveying channel rapidly conveys material. When the electronic weighing device measures that the material weight reaches 80% of the set threshold, the coarse feeding stage stops, the fine feeding device enters the coarse feeding stage, the fine feeding gate is open and gradually releases the material in the fine conveying channel, and at the same time, the material in the coarse conveying channel is simultaneously emptied until the electronic weighing device measures that the material weight reaches 100% of the set threshold, at which point the fine feeding stage stops. By adopting the above-mentioned graded switching control logic for coarse and fine feeding, a precise feeding mode of "large flow coarse filling in the early stage and small flow fine filling in the later stage" is constructed. In the coarse feeding stage, the fine material channel is closed for material storage while the coarse material channel discharges rapidly, significantly improving packaging filling efficiency and shortening the single packaging cycle. When the weighing reaches 80% of the threshold, the coarse feeding is stopped and the fine feeding is started. The material stored in the fine material channel is used for precise replenishment, avoiding weighing errors caused by the inertia of high-flow-rate feeding. At the same time, combined with the independent vibration and linkage vibration modes of the corresponding stages, it ensures that the coarse feeding is fast and unblocked, and the fine feeding is accurate and stable. This completely solves the problems of large feeding inertia, high weighing error, and poor connection between fast and slow feeding in traditional equipment, maximizing the improvement of packaging weighing accuracy.

[0018] The beneficial effects of this invention are: 1. Solves the problem of material agglomeration and blockage, and greatly improves the stability of material feeding: This equipment is designed with differentiated vibration anti-blockage modes for different working conditions of coarse and fine feeding. In the coarse feeding stage, the coarse material channel vibrates independently to break up large carbon black agglomerates and break up material bridging; in the fine feeding stage, the fine material channel vibrates in conjunction with the coarse material channel to break up fine agglomerated particles. It achieves anti-agglomeration and anti-blockage throughout the entire process, completely eliminating the problems of material interruption, jamming and flow fluctuation, and ensuring uniform and stable material conveying throughout the entire process. 2. Graded vibration adaptive switching, low energy consumption and low equipment wear: The pure mechanical adaptive vibration switching structure is adopted. It relies on the gravity of the material and the elasticity of the spring to realize the automatic switching of two-level working condition vibration modes. No additional electrical control or pneumatic auxiliary structure is required. Vibration of the corresponding material channel is activated only in the corresponding working condition to avoid ineffective vibration, which greatly reduces the energy consumption of equipment operation. At the same time, it reduces the wear of components caused by long-term empty vibration of the structure, extends the overall service life of the equipment, and reduces operation and maintenance costs. 3. Significantly improved packaging weighing accuracy and greatly increased product qualification rate: Adopting the graded feeding logic of "80% coarse filling + 20% fine filling" and combined with stable vibration feeding guarantee, it not only improves packaging efficiency through large flow coarse feeding, but also eliminates feeding inertia error and flow fluctuation error through precise and controllable fine feeding. It solves the problem of weighing over-tolerance and under-tolerance in traditional equipment, greatly improves the accuracy and consistency of ton bag packaging weight, and reduces the defect rate. 4. Strong structural linkage, stable operation and low failure rate: The dual-channel split flow structure enables independent conveying of coarse and fine materials without interference; the cylinder linkage drive structure ensures precise transmission and small gaps, guaranteeing accurate and controllable opening and closing of the precision arc gate; the overall vibration transmission structure is reasonably designed and fits stably, with low vibration energy loss and uniform transmission, ensuring stable overall equipment operation and very few failures such as jamming, material leakage, or malfunction. 5. Wide adaptability and strong production compatibility: The overall structure is compact and the layout is reasonable. It can be directly adapted to existing conventional carbon black ton bag packaging production lines without major modifications to the main structure of the equipment. The modification cost is low. It can adapt to the packaging of carbon black granules with different particle sizes and moisture content. It has extremely strong versatility and practicality. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1 to 5As shown, a coarse and fine feeding combined vibration anti-caking carbon black ton bag packaging equipment is provided. It is sequentially connected from top to bottom to include a material distribution device 1, a feeding device, an electronic weighing device 2, and a bag clamping device 3. The material distribution device 1 is connected to the bottom of a storage hopper (not shown in the figure). The material distribution device 1 includes a coarse feeding device 4 and a fine feeding device 5. The electronic weighing device 2 and the bag clamping device 3 are conventional structures in existing packaging equipment; their detailed structures can be found in existing technologies. The core improvement lies in the following: an electromagnetic vibrator 6 is installed on the side of the coarse feeding device 4. When the coarse feeding device 4 is in the coarse feeding stage, the electromagnetic vibrator 6 directly transmits vibrations continuously to the conveying channel within the coarse feeding device 4. A vibration transmission device 7, which can be linked to the conveying channel within the fine feeding device 5, is also installed on the conveying channel within the coarse feeding device 4. When the fine feeding device 5 is in the fine feeding stage, the electromagnetic vibrator 6 indirectly transmits vibrations continuously to the conveying channel within the fine feeding device 5 through the vibration transmission device 7. This equipment features a two-stage coarse and fine feeding linkage vibration structure, which differs from traditional single-weight feeding structures without vibration anti-clogging. In the coarse feeding stage, the electromagnetic vibrator 6 directly drives the coarse feeding conveyor to vibrate, which can break up the large-volume carbon black agglomerates accumulated and clumps in the coarse feeding channel in real time, eliminate material bridging, and ensure high-flow, continuous, and stable feeding in the coarse feeding stage, avoiding problems such as jamming, material interruption, and flow fluctuations. In the fine feeding stage, the vibration energy of the electromagnetic vibrator 6 is linked and transmitted through the vibration transmission device 7, which indirectly drives the fine feeding conveyor to vibrate, breaking up small carbon black clumps and suspended agglomerates in the fine feeding channel, ensuring the uniformity of small-flow fine feeding, and fundamentally solving the problems of carbon black feeding blockage and unstable flow. This provides a stable material conveying foundation for the accurate metering of the electronic weighing device 2 and significantly reduces weighing errors.

[0024] like Figures 3 to 5 As shown, the material distribution device 1 includes a left material distribution channel 11 and a right material distribution channel 12 arranged sequentially on the left and right sides. The top openings of the left material distribution channel 11 and the right material distribution channel 12 are integrated, while the bottom openings of the left material distribution channel 11 and the right material distribution channel 12 are separate. By adopting a dual material distribution channel structure with separate top and independent bottom, the integrated top opening can uniformly receive the carbon black material falling from the storage hopper, realizing centralized material diversion and avoiding material scattering and waste. The separate bottom openings can realize that the left and right material distribution channels 12 can independently correspond to the coarse and fine feeding devices 5, realizing independent conveying of two material streams without interference. At the same time, this structure can accurately distinguish between the coarse feeding material stream and the fine feeding material stream, avoiding the problems of disordered material flow and agglomeration caused by the mixing of coarse and fine materials. It also improves the overall structural stability of the material distribution device 1, providing structural support for the stable operation of subsequent graded vibration and graded feeding.

[0025] Continue as Figures 3 to 5As shown, the coarse feeding device 4 includes a feeder box 41, a horizontally inclined coarse conveying channel 42 is provided on the right side of the feeder box 41, and a coarse baffle plate 43 is provided inside the feeder box 41 near the outlet of the coarse conveying channel 42 and conveying the material downward; wherein, the electromagnetic vibrator 6 is fixed to the bottom side of the coarse conveying channel 42, and it can vibrate under the action of the electromagnetic vibrator 6. The horizontally inclined coarse conveying channel 42 is adapted to the high-flow, rapid material discharge requirements of the coarse feeding stage. The inclined structure enables gravity-flow material conveying, improving coarse feeding efficiency. The electromagnetic vibrator 6 fixed to the bottom side can transmit vibration energy at close range and efficiently, ensuring uniform vibration throughout the coarse conveying channel 42 without any vibration dead zones, and thoroughly breaking up the accumulated clumps of carbon black in the channel. The built-in coarse baffle 43 can guide and limit the flow of coarse material, preventing splashing and deviation during high-flow material discharge, and constraining the material to be conveyed vertically downward, ensuring a stable material conveying trajectory. This structure optimizes the conveying path and vibration effect of coarse feeding, effectively solving the problems of material accumulation, clumping and blockage, and material deviation during high-flow coarse feeding, ensuring a stable, efficient, and continuous material flow during the coarse feeding stage.

[0026] Continue as Figures 3 to 5 As shown, the fine feeding device 5 includes a fine conveying channel 51 installed inside the feeder box 41 and connected to the left distribution channel 11. A fine feeding arc gate 52 is installed at the bottom of the fine conveying channel 51. The fine feeding arc gate 52 can swing left and right under the drive of the swing drive assembly outside the feeder box 41. When the fine feeding arc gate 52 swings, it can open or close the outlet at the bottom of the fine conveying channel 51. A sealing baffle 53 fixed on the fine conveying channel 51 is provided at the outlet. The built-in precision conveying channel 51 has a compact structure and can be precisely connected with the left-side distribution channel to achieve stable storage and conveying of precision materials. The precision feeding arc gate 52 is driven to swing left and right by the swing drive assembly, which can precisely control the opening and closing amplitude and speed of the precision material channel outlet, so as to achieve fine-tuned feeding with small flow and high precision, and adapt to the needs of precise replenishment in the later stage of weighing. The sealing baffle 53 set at the outlet can achieve flexible sealing during the opening and closing of the arc gate, preventing the leakage of fine carbon black dust during the precision feeding stage, and avoiding the problem of incomplete closure and material leakage caused by dust stuck in the arc gate gap, ensuring accurate start and stop of feeding and no material leakage during the precision feeding stage, and further improving the weighing and metering accuracy.

[0027] like Figure 6As shown, the swing drive assembly includes a horizontally positioned swing cylinder 54. A straight arm 55 is coaxially connected to the telescopic section of the swing cylinder 54. At the end of the straight arm 55, a rocker arm 57, extending through to the top of the feeder housing 41, is rotatably mounted via a rotating arm 56. The precision feeding arc gate 52 is fixedly connected to the rocker arm 57 and swings left and right around the rocker arm 57. The drive structure, employing a cylinder + connecting rod rocker arm 57, ensures precise transmission, stable operation, and fast response. The horizontal telescopic movement of the swing cylinder 54 drives the straight arm 55 and the rotating arm 56 in conjunction, thereby driving the rocker arm 57 to swing precisely, achieving smooth opening and closing of the precision feeding arc gate 52. This transmission structure features small transmission gaps and high operational precision, allowing for precise control of the arc gate's swing angle, thereby accurately adjusting the flow cross-sectional area for precision feeding and achieving refined control of the feeding flow rate.

[0028] like Figures 3 to 5 As shown, the left side of the feeder box 41 is connected to an upwardly extending dust collection nozzle 44, which can be directly connected to external dust collection equipment to accurately collect the fine carbon black dust generated during the feeding process inside the feeder box 41. Dust is easily generated during the vibration of the carbon black material during feeding. The dust collection nozzle 44 can promptly extract the suspended dust inside the box, preventing dust accumulation in the fine conveying channel 51 and the arc gate transmission structure, thus preventing dust agglomeration and blockage of the material channel and transmission components.

[0029] like Figures 7 to 10As shown, the vibration transmission device 7 includes a vibration seat 71 fixed to the top of the coarse conveying channel 42 and extending into the feeder housing 41. Multiple vibration supports 72 aligned in a straight line are fixedly connected to the vibration seat 71. Each vibration support 72 has a cutout 73 at its top that engages with the wall of the rocker arm 57. Vertically arranged vibration guide rods 74 are also provided on both the front and rear sides of the coarse conveying channel 42. Vibration ears 75, which can move up and down along the vibration guide rods 74, are connected to the front and rear sides of the coarse conveying channel 42. A push spring 76 is fitted onto the vibration guide rod 74 to continuously push the vibration ears 75 upwards. All the cutouts 73 of the vibration supports 72 can contact the wall of the rocker arm 57 under the elastic action of the push spring 76. This mechanical vibration transmission device 7 can achieve precise and stable linkage transmission of the vibration energy of the electromagnetic vibrator 6. The elastic thrust of the push spring 76 continuously pushes the vibrating side ear 75, ensuring that the top cut 73 of the vibrating bracket 72 always fits against the wall of the rocker arm 57, thus constructing a stable vibration transmission path. The vibration energy of the coarse conveying channel 42 is transmitted to the fine feeding arc gate 52 and the fine conveying channel 51 through the vibrating seat 71, the vibrating bracket 72, and the rocker arm 57, achieving synchronous vibration of the fine material channel to prevent clumping. The vibrating guide rod 74, in conjunction with the vibrating side ear 75, can limit the up and down movement trajectory of the coarse conveying channel 42, ensuring the stability of the structure and avoiding deviation and jamming. Multiple sets of coaxially arranged vibrating brackets 72 can evenly distribute the vibration energy, ensuring that the rocker arm 57 is subjected to uniform force throughout, guaranteeing uniform vibration of the fine material channel without dead angles, and solving the problem of agglomeration and clumping of fine carbon black during the fine feeding stage.

[0030] like Figures 9 to 10 As shown, the cross-sectional shape of the cut 73 is triangular, which has the advantages of sharp corner guidance, good fit and high wear resistance. It can form a precise line contact fit with the cylindrical rocker arm 57 wall. The contact position is precise and the force is concentrated, which can maximize the transmission of vibration energy and reduce vibration transmission loss.

[0031] Continue as Figures 9 to 10As shown, the inlet and outlet of the coarse conveying channel 42 are sequentially connected to the right distribution channel 12 and the feeder box 41, and the entire coarse conveying channel 42 can move up and down. When the coarse feeding device 4 is in the coarse feeding stage, the material will press down on the coarse conveying channel 42, thereby causing all the vibrating supports 72 and rocker arms 57 to separate up and down. When the fine feeding device is in the fine feeding stage, the coarse conveying channel 42 will move upward to reset because there is no material pressing down, and under the action of the push spring 76, all the vibrating supports 72 and rocker arms 57 will contact up and down. The design of the coarse conveying channel 42, which can float up and down, enables automatic switching of vibration modes between the coarse and fine feeding stages. It requires no electrical control intervention and is purely mechanically adaptive, with precise response and zero delay. During the coarse feeding stage, the material gravity presses down on the coarse conveying channel 42, causing the vibration support 72 to separate from the rocker arm 57. The vibration energy is only applied to the coarse conveying channel 42, focusing on breaking up large clumps in the coarse material channel, avoiding the dispersion of vibration energy, and ensuring the anti-bridging and anti-blocking effect of coarse material feeding. During the fine feeding stage, there is no material pressing down on the coarse material channel. The push spring 76 drives the coarse conveying channel 42 to reset, and the vibration support 72 and the rocker arm 57 are in contact. The vibration energy is transmitted to the fine material channel in a linkage manner, achieving targeted anti-clumping feeding of the fine material channel.

[0032] Continue as Figures 9 to 10 As shown, when the coarse feeding device 4 is in the coarse feeding stage, the fine feeding arc gate 52 of the fine feeding device is normally closed. At this time, the fine conveying channel of the entire fine feeding device is completely filled with material, and the coarse conveying channel 42 rapidly conveys material. When the electronic weighing device 2 measures that the weight of the material reaches 80% of the set threshold, the coarse feeding stage stops, the fine feeding device enters the coarse feeding stage, the fine feeding arc gate 52 is in the open state and gradually releases the material in the fine conveying channel. At the same time, the material in the coarse conveying channel 42 is simultaneously emptied until the weight of the material measured by the electronic weighing device 2 reaches 100% of the set threshold, at which point the fine feeding stage stops. By adopting the above-mentioned graded switching control logic for coarse and fine feeding, a precise feeding mode of "large flow coarse filling in the early stage and small flow fine filling in the later stage" is constructed. In the coarse feeding stage, the fine material channel is closed for material storage while the coarse material channel discharges rapidly, significantly improving packaging filling efficiency and shortening the single packaging cycle. When the weighing reaches 80% of the threshold, the coarse feeding is stopped and the fine feeding is started. The material stored in the fine material channel is used for precise replenishment, avoiding weighing errors caused by the inertia of high-flow-rate feeding. At the same time, combined with the independent vibration and linkage vibration modes of the corresponding stages, it ensures that the coarse feeding is fast and unblocked, and the fine feeding is accurate and stable. This completely solves the problems of large feeding inertia, high weighing error, and poor connection between fast and slow feeding in traditional equipment, maximizing the improvement of packaging weighing accuracy.

[0033] like Figures 1 to 10As shown, this coarse and fine feeding combined vibration anti-caking carbon black ton bag packaging equipment adopts a top-down material conveying structure. During operation, the ton bags to be packaged are first fixed by the bag clamp device 3. After the equipment is turned on, the graded feeding and packaging process begins. The entire process is divided into a coarse feeding operation stage and a fine feeding operation stage. The two-stage working conditions are precisely adapted through a mechanical adaptive vibration switching structure. The specific working process is as follows: The first step is to load the equipment into standby mode. The carbon black material in the storage hopper enters the distribution device 1 through the integrated top opening and is divided into the left distribution channel 11 and the right distribution channel 12. The left distribution channel 11 stores the material inside the fine conveying channel 51. At this time, the swing drive assembly controls the fine feeding arc gate 52 to remain in a normally closed state, so that the fine channel is full of material. The material in the right distribution channel 12 falls into the coarse conveying channel 42, and the equipment enters the coarse feeding stage.

[0034] The second step, the coarse feeding stage, involves the continuous filling of the coarse conveying channel 42 with material. The material's own weight presses down on the channel, causing it to move downwards along the vibrating guide rod 74. This causes the vibrating side lug 75 to compress the push spring 76, simultaneously separating the triangular cut 73 at the top of the vibrating support 72 from the rocker arm 57, cutting off the vibration linkage path. At this time, the electromagnetic vibrator 6 starts, directly applying continuous vibration to the coarse conveying channel 42, breaking up the large, clump-like carbon black material accumulated within the channel, eliminating material bridging and blockages. Under the guiding effect of the inclined coarse conveying channel 42 and the coarse baffle plate 43, the material is conveyed downwards in a large flow rate, continuously and stably, falling above the electronic weighing device 2. The electronic weighing device 2 monitors the total weight of the material in real time. During this stage, the equipment rapidly fills the material, improving packaging efficiency.

[0035] The third step is the switching of operating conditions. When the electronic weighing device 2 detects that the material weight has reached 80% of the preset total weight threshold, the equipment automatically shuts down the coarse feeding process, and the material in the coarse conveying channel 42 continues to be emptied, and the material's gravity gradually disappears. At this time, the compressed push spring 76 releases its elastic thrust, pushing the vibrating side ear 75 to move upward along the vibrating guide rod 74, driving the coarse conveying channel 42 to reset as a whole, so that the triangular cut 73 at the top of the vibrating bracket 72 fits tightly against the rocker arm 57 wall again, establishing a stable vibration transmission path.

[0036] The fourth step, the fine feeding stage, involves the extension and retraction of the swing cylinder 54 of the swing drive assembly, which in turn drives the straight arm 55 and the rotating arm 56 to swing the rocker arm 57 slightly left and right. This, in turn, causes the fine feeding arc gate 52 to open slowly, allowing the carbon black material stored in the fine conveying channel 51 to fall at a uniform speed. Simultaneously, the electromagnetic vibrator 6 continues to operate, transmitting vibration energy through the coarse conveying channel 42, vibrating seat 71, vibrating support 72, and rocker arm 57 to the fine feeding arc gate 52 and the fine conveying channel 51. This vibration disperses the fine carbon black agglomerates within the fine conveying channel, preventing fine clumps from clogging it and ensuring a uniform and precise descent of small-volume materials. The sealing baffle 53 provides a flexible seal throughout the process, preventing dust leakage and material spillage. The dust removal nozzle 44 is simultaneously connected to the dust removal equipment to extract suspended dust from the machine casing.

[0037] Fifth step, the operation ends. The electronic weighing device 2 continuously monitors the weight of the finely fed material. When the total weight of the material reaches the preset 100% threshold, the equipment immediately shuts down the fine feeding process. The swing cylinder 54 drives the arc gate to reset and close, stopping the feeding and completing the single carbon black ton bag precision packaging operation. Then the ton bag is replaced and the next packaging cycle begins.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
