Description

Technical Field

[0001] This utility model relates to the field of solid material dispensing equipment, and in particular to a dispensing system. Background Technology

[0002] In related technologies, in the industrial production field, the feeding system is a key piece of equipment for the automatic addition of raw materials, reactants, catalysts, and other materials. Its operational stability and feeding accuracy directly affect production efficiency and product quality, and it is widely used in various industrial production scenarios. Specifically, for the feeding of rod-shaped materials, existing technologies generally employ a feeding roller conveyor system: by setting grooves on the surface of the feeding roller, the rotation of the roller drives the rod-shaped material within the grooves to move, thereby completing the continuous feeding of materials. However, the groove dimensions on the surface of the feeding rollers in existing feeding systems are typically fixed and cannot be adjusted to fit the diameter of the actual feeding rod-shaped materials. In actual production, the feeding rod-shaped materials often have inconsistent diameters. When feeding thinner rod-shaped materials, it is highly likely that two or more materials will simultaneously become stuck in the same groove of the feeding roller. This problem not only causes the feeding roller to jam, interrupting the feeding operation and severely impacting production efficiency, but it can also damage the feeding roller and other related components of the feeding system due to the force generated by material compression, increasing equipment maintenance costs and production safety risks. This makes it difficult to meet the stability and adaptability requirements of industrial production for feeding systems. Utility Model Content

[0021] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings. In the absence of conflict, the following embodiments and implementation methods can be combined with each other.

[0022] An exemplary embodiment of this utility model provides a feeding system, such as... Figure 1 As shown, the feeding system includes a feeding box 10, a material storage compartment 20, and a feeding assembly 30 disposed within the feeding box 10.

[0023] like Figures 1-3 As shown, the bottom of the feeding box 10 is provided with a discharge port 101. A material chamber 20 is located in the upper part of the feeding box 10 and has a material chamber 20 outlet; the material chamber 20 is used to store material 40. The feeding assembly 30 includes a feeding plate 301 and a feeding roller 302. The feeding plate 301 is located inside the feeding box 10 and corresponds to the outlet of the material chamber 20; the feeding plate 301 cooperates with the material chamber 20 to form a feeding channel to transport material 40. The feeding roller 302 is located at the outlet of the feeding channel and corresponds to the discharge port 101; the feeding roller 302 is used to feed material 40 to the discharge port 101. The feeding roller 302 includes: a roller body 3021, an adjusting baffle 3023, and an adjusting component 3024. The roller body 3021 is provided with a receiving groove 3021A corresponding to the outlet of the feeding channel; the adjusting baffle 3023 is rotatably disposed in the receiving groove 3021A; the adjusting member 3024 is used to adjust the relative position of the adjusting baffle 3023 and the receiving groove 3021A on its rotation path, so as to change the capacity of the receiving groove 3021A.

[0024] The feeding system stores rod-shaped materials 40 in the material chamber 20 inside the feeding box 10. The feeding channel formed by the feeding plate 301 and the outlet of the material chamber 20 guides and conveys the materials 40. The feeding roller 302 is set at the outlet of the feeding channel and the discharge port 101 to receive and feed the materials 40. The roller body 3021 of the feeding roller 302 is provided with a receiving groove 3021A to receive the materials 40. The adjusting baffle 3023 in the receiving groove 3021A is driven to rotate by the adjusting component 3024 to change the relative position of the adjusting baffle 3023 and the receiving groove 3021A, thereby flexibly adjusting the effective capacity of the receiving groove 3021A.

[0025] In this exemplary embodiment, as Figure 1 , Figures 4-5 As shown, the capacity of the receiving trough 3021A can be flexibly adapted to rod-shaped materials 40 of different diameters by adjusting the baffle 3023, avoiding the simultaneous embedding of multiple small-diameter materials 40 and completely solving the problem of jamming of the feeding roller 302. Multiple specifications of materials 40 can be adapted without replacing the feeding roller 302, reducing equipment replacement costs and operational complexity, and improving production adaptability. It ensures continuous and stable feeding action, avoids production interruptions caused by jamming, improves production efficiency, and reduces the risk of equipment overload, component wear, and other malfunctions, extending the service life of the feeding system.

[0026] It should be understood that the change in the relative position of the adjusting baffle 3023 and the receiving groove 3021A of the material roller body 3021 can be achieved by adjusting the angle between the two when using the above-mentioned rotatable connection; or by changing the distance between the adjusting baffle 3023 and the receiving groove 3021A of the material roller body 3021, that is, only the depth of the adjusting baffle 3023 in the receiving groove 3021A needs to be changed.

[0027] In some exemplary embodiments, such as Figures 2-3 As shown, the receiving groove 3021A has a mounting part 3022 at its opening; the first side of the adjusting baffle 3023 is rotatably mounted on the mounting part 3022, and the second side of the adjusting baffle 3023, which is opposite to the first side, extends into the receiving groove 3021A.

[0028] In this exemplary embodiment, the rotating connection structure between the mounting part 3022 and the first side of the adjusting baffle 3023 ensures that the adjusting baffle 3023 is stably assembled at the opening of the receiving groove 3021A, and the rotation process is smooth and without jamming, ensuring the reliability of the capacity adjustment of the receiving groove 3021A. The second side of the adjusting baffle 3023 extends into the receiving groove 3021A, which can precisely change the effective bearing space of the receiving groove 3021A. When adapting to rod-shaped materials 40 of different diameters, it can accurately control the number of materials 40 received at one time, further avoiding the problem of multiple thin materials being embedded at the same time. The feeding roller 302 has a simple and compact structural design, requiring no additional complex connecting parts, which facilitates installation and maintenance on the feeding roller 302 body, while not affecting the receiving and feeding process of the material 40 in the receiving groove 3021A, ensuring feeding efficiency.

[0029] It should be understood that the mounting part 3022 can also be located within the receiving groove 3021A, so that the relative position of the adjusting baffle 3023 and the material roller body 3021 can be changed to adjust the capacity of the receiving groove 3021A. Of course, there can be multiple adjusting baffles 3023. When multiple adjusting baffles 3023 are provided, they can be arranged at intervals along the length of the receiving groove 3021A, and the mounting part 3022 can be provided corresponding to the adjusting baffles 3023.

[0030] In some exemplary embodiments, such as Figure 3 As shown, the mounting part 3022 includes a pair of curved arms arranged opposite each other along the length of the receiving groove 3021A. The fixed ends of the curved arms are connected to the opening of the receiving groove 3021A, and the free ends of the curved arms are used to hinge with the adjusting baffle 3023. A clearance space is formed between the pair of curved arms to avoid the rotation path of the adjusting baffle 3023.

[0031] In some exemplary embodiments, such as Figures 2-5 As shown, the free end of the crank arm is provided with a hinge seat, and the first side of the adjusting baffle 3023 is provided with a hinge shaft that cooperates with the hinge seat. The adjusting baffle 3023 forms a rotational engagement with the hinge seat at the free end of the crank arm through the hinge shaft provided on the first side, realizing the rotatable assembly of the adjusting baffle 3023 in the mounting part 3022 of the receiving groove 3021A; with the drive of the adjusting component 3024, the position of the second side of the adjusting baffle 3023 in the receiving groove 3021A can be precisely adjusted by controlling the rotation angle of the hinge shaft, thereby changing the effective capacity of the receiving groove 3021A.

[0032] In this exemplary embodiment, the fitting structure between the hinge shaft and the hinge seat allows for smoother and more flexible rotation of the adjusting baffle 3023, reducing the risk of jamming during adjustment and ensuring the accuracy and stability of the capacity adjustment of the receiving trough 3021A. The assembly process is simple, and the hinge structure facilitates disassembly and maintenance, reducing equipment repair costs. Simultaneously, it does not occupy excessive internal space in the receiving trough 3021A and does not affect the normal receiving and feeding of materials 40.

[0033] In some exemplary embodiments, such as Figures 2-5 As shown, the adjusting baffle 3023 is a curved plate. The adjusting baffle 3023 includes a first curved plate segment 3023A and a second curved plate segment 3023B connected sequentially in the extending direction of the adjusting baffle 3023. The first curved plate segment 3023A has the same bending direction as the inner wall of the receiving groove 3021A, and is configured to cooperate with the inner wall of the receiving groove 3021A to adjust the capacity of the receiving groove 3021A. The second curved plate segment 3023B extends along a predetermined circumferential direction with the first side of the adjusting baffle 3023 as an axis, and is configured to cooperate with the adjusting member 3024 to adjust the relative position of the adjusting baffle 3023 and the receiving groove 3021A on its rotation path.

[0034] The first curved plate segment 3023A bends in the same direction as the inner wall of the receiving trough 3021A, effectively conforming to the contour of the inner wall of the receiving trough 3021A or serving as part of the inner wall of the receiving trough 3021A (corresponding to filling the clearance space) to precisely adjust the effective capacity of the receiving trough 3021A, thus ensuring smooth feeding. The second curved plate segment 3023B bends and extends along a preset circumferential direction to facilitate cooperation with the adjusting component 3024, making the rotation of the adjusting baffle 3023 more precise, while improving the stability of the adjustment process and avoiding jamming or shaking. The overall structure of the curved plate is adapted to the flow trajectory of the material 40, buffering the impact when the rod-shaped material 40 is fed in, reducing wear on the adjusting baffle 3023 and the hinge structure, and extending the service life of the components; moreover, the segmented bending design takes into account both capacity adjustment and power coordination, resulting in a compact structure and high efficiency.

[0035] In some exemplary embodiments, such as Figure 3 As shown, the second curved plate segment 3023B is provided with an elongated hole 3023C opened along a preset circumferential direction; the adjusting member 3024 includes: a locking hole provided on the material roller body 3021; ​​and a fastener for fixing the locking hole and the elongated hole 3023C.

[0036] The elongated hole 3023C is set along a preset circumferential direction. It can be fixed to the locking hole at different positions within the elongated hole 3023C by fasteners, enabling stepless adjustment of the rotation angle of the adjustment baffle 3023. This allows for precise adaptation to rod-shaped materials 40 of any diameter range, offering a wider adaptability range than multi-adjustment hole structures. The stepless adjustment method eliminates the need for gear switching, allowing for flexible fine-tuning of the effective capacity of the receiving groove 3021A according to the actual diameter of the material 40, resulting in higher adjustment precision and further preventing issues such as multiple thin materials becoming embedded or the inability to accept coarse materials. The structural design is simple, the elongated hole 3023C is easy to manufacture and cost-effective, and the fasteners and locking holes provide a stable fixation method that can withstand equipment vibration and material impact. Furthermore, the adjustment operation is intuitive and convenient, requiring no complex tools, thus improving the efficiency of material specification switching during production.

[0037] In an alternative to the "setting elongated hole 3023C" method, the second curved plate segment 3023B is provided with a plurality of adjustment holes (not shown in the figure) spaced apart along a predetermined circumferential direction. Accordingly, the adjustment member 3024 includes: a locking hole provided on the roller body 3021; ​​and a fastener for fixing the locking hole to one of the plurality of adjustment holes.

[0038] Multiple adjustment holes are spaced apart along a preset circumference. By selecting different adjustment holes and locking holes for fixation, the rotation angle of the baffle 3023 can be precisely positioned at multiple levels to accommodate the receiving needs of rod-shaped materials 40 of different diameters. The fasteners, together with the fixing structure of the locking holes and adjustment holes, ensure a stable and reliable connection, resisting the impact of the material 40 and the vibration of the equipment during operation, preventing positional shift after adjustment, and ensuring the stability of the feeding process. The adjustment operation is simple and convenient, requiring no complicated tools to complete the gear switching, reducing the difficulty of operation for workers, improving the efficiency of material 40 specification change during production, and the structure is low in cost and easy to process and maintain.

[0039] In some exemplary embodiments, such as Figure 1 As shown, the feeding plate 301 is inclinedly arranged inside the feeding box 10 and gradually decreases in height along the feeding channel conveying direction; the material chamber 20 includes: multiple sub-material chambers 201 arranged in the upper part of the feeding box 10, each of the multiple sub-material chambers 201 having a material chamber 20 outlet connected to the feeding channel, for storing materials 40 of different bar diameters. The height of the material chamber 20 outlets of the multiple sub-material chambers 201 decreases sequentially along the feeding channel conveying direction. The feeding plate 301 is inclined to form a guide feeding channel, which uses gravity to guide the material 40 to be smoothly conveyed towards the feeding roller 302. Multiple sub-material compartments 201 are independently set on the upper part of the feeding box 10, which store rod-shaped materials 40 of different diameters. The material compartment 20 outlets of each sub-material compartment 201 are successively lowered along the conveying direction of the feeding channel, so that the material 40 in different sub-material compartments 201 can be orderly merged into the feeding channel along the inclined feeding plate 301 and finally accurately conveyed to the receiving groove 3021A of the feeding roller 302.

[0040] In this exemplary embodiment, multiple sub-material compartments 201 enable the classified storage of materials 40 with different diameters. Combined with progressively decreasing outlet heights, this prevents mixing of materials 40 of different specifications. Simultaneously, it adapts to the gravity conveying of the inclined feed plate 301, ensuring orderly and unobstructed material transport. The inclined feed plate 301 utilizes gravity-assisted conveying to reduce the accumulation of materials 40 within the channel, improving feeding efficiency. Furthermore, it requires no additional power drive, reducing energy consumption and equipment failure rate. Continuous feeding of multiple specifications of materials 40 can be achieved without frequent replacement or adjustment of storage devices, adapting to the multi-variety, multi-batch production needs in chemical production, reducing operational complexity, and improving production flexibility.

[0041] In some exemplary embodiments, such as Figure 1 As shown, the feeding system also includes: multiple sub-material chamber doors 202, which correspond one-to-one with multiple sub-material chambers 201, for independently opening and closing the material chamber 20 outlets of multiple sub-material chambers 201.

[0042] In this exemplary embodiment, the central control unit of the feeding system sends an independent control signal (the signal form may include electrical signal, pneumatic signal or hydraulic signal, depending on the door drive method) to the bin door controller corresponding to the target sub-material bin 201 according to the preset feeding formula (such as the ratio and feeding order of different materials 40) or real-time operation instructions.

[0043] After receiving the signal, the door controller drives the corresponding actuator (such as electric push rod, cylinder, hydraulic cylinder, etc.) to start. Taking electric push rod drive as an example, the push rod will extend and retract according to the signal command, causing the moving parts (such as gate, flap) of the sub-material compartment door 202 to move; if it is pneumatically driven, the piston is pushed to open and close the sub-material compartment door 202 by controlling the air supply.

[0044] When the movable part of the sub-material storage room door 202 moves to the "open" position, the material room 20 outlet of the sub-material storage room 201 is opened, and the material 40 stored in the storage room enters the subsequent conveying pipeline, metering device or mixing equipment along the outlet under the action of gravity (or with the negative pressure / pushing force of the downstream conveying equipment); when the preset feeding amount is reached (judged by the feedback signals of the weight sensor and flow sensor in the system) or the feeding cycle is completed, the central control unit sends a "close" command, drives the mechanism to reverse, drives the sub-material storage room door 202 to reset, seals the material room 20 outlet, and terminates the feeding of material 40 into the sub-material storage room 201.

[0045] The sub-material storage door 202 is equipped with a position sensor (such as a proximity switch or limit switch) that provides real-time feedback to the central control unit on the current status of the sub-material storage door 202 ("fully open", "partially open", "fully closed") during the opening and closing process. If any abnormality occurs, such as jamming or incomplete closure of the sub-material storage door 202, the sensor will trigger an alarm signal, and the central control unit can suspend the operation of the sub-material storage door 201 and indicate the fault, forming a closed-loop control of "command-execution-feedback-adjustment".

[0046] In some exemplary embodiments, the feeding system further includes a drive mechanism disposed within the feeding box 10 for driving the feeding roller 302 to rotate so as to feed the material 40 to the discharge port 101.

[0047] In this exemplary embodiment, when the sub-material compartment door 202 is closed, the feeding roller 302 remains stationary (the receiving trough 3021A faces the feeding channel outlet), and the material 40 is stored in the sub-material compartment 201 and will not enter the area of ​​the feeding roller 302. After receiving the feeding command, the central control unit of the feeding system first controls the target sub-material compartment door 202 to open, and the material 40 is sent to the receiving trough 3021A of the feeding roller 302 under the action of gravity; the drive mechanism starts, driving the feeding roller 302 to rotate, and the falling material 40 is evenly scraped and transported to the discharge port 101 based on the receiving trough 3021A. After the preset feeding amount is reached, the system first stops the drive mechanism, the feeding roller 302 stops rotating, and then closes the sub-material compartment door 202 to avoid material 40 residue or excessive feeding.

[0048] Of course, the opening and closing of the sub-material compartment door 202 can also be used to control the quantity of material 40 fed into the feeding channel, so as to avoid material 40 remaining or accumulating excessively in the feeding channel during the operation of the feeding roller 302. This process will not be described in detail here.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
