Description

Technical Field

[0001] This invention relates to the field of pharmaceutical material conveying technology, and in particular to a feeding device and feeding control system. Background Technology

[0002] In continuous production industries such as pharmaceuticals and food processing, the continuous and stable operation of production lines is the core of improving production efficiency and ensuring product quality. The continuous and stable transport of materials from the workshop discharge port to the equipment feed port is the key link to achieve continuous operation of the production line.

[0003] After adding a new packaging production line, the company faced constraints due to on-site installation conditions: the original material inlet in the workshop was fixed and could not be moved, and the new equipment was quite tall, resulting in a small height difference and a large horizontal distance between the new equipment's inlet and the original material inlet, making direct connection impossible. Currently, manual repetitive feeding is still used to add materials, which not only results in high labor costs, low feeding efficiency, and uneven feeding frequency, failing to meet the requirements of continuous production, but also easily leads to inconsistent material addition amounts due to human error, affecting product quality stability.

[0004] Meanwhile, the materials to be conveyed are diverse in type and have different characteristics. The material flow characteristics place strict requirements on the adaptability of the feeding pipeline. It is necessary to prevent material blockage and bridging, and also to meet the process requirements of simultaneous feeding from two material inlets. The performance of the feeding and conveying structure directly determines the production efficiency and the quality of material conveying.

[0005] While existing technologies include vibrating feeding devices, they are mostly applicable to the rear end of the equipment, allowing materials in the hopper to fall into the medicine container via the vibrating device. Such devices cannot be adapted to the complex installation conditions described above.

[0006] At present, due to the lack of an efficient and suitable material feeding connection structure between the equipment inlet and the workshop outlet, the production line cannot achieve continuous and automated production, which has become a key bottleneck restricting the improvement of enterprise capacity and the assurance of product quality. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the defects of low single-outlet feeding efficiency, strong angle dependence of gravity conveying, and easy bridging and retention of materials in the prior art, and to provide a feeding device and feeding control system.

[0008] The present invention solves the above-mentioned technical problems through the following technical solution:

[0009] A feeding device includes a feeding pipe assembly connected to a discharge port, the feeding pipe assembly including feeding pipes, and the number of feeding pipes is at least two.

[0010] The feeding device further includes a material distribution structure, which is disposed between the discharge port and the feeding pipe. The material distribution structure is configured to divide the material output from the discharge port into each feeding pipe. The material distribution structure also includes multiple material distribution openings, which are provided corresponding to each feeding pipe.

[0011] The feeding device also includes a vibrator, which is located below the feeding pipe and corresponds to the material distribution opening. The vibrator is detachably connected to the feeding pipe.

[0012] In this scheme, the feeding device is equipped with at least two independent feeding pipes, and through the material distribution structure between the discharge port and the feeding pipe, the single outlet material is naturally divided into multiple non-interfering discharge branches, so as to realize synchronous and equal pressure feeding of dual stations. Compared to a single discharge branch scheme, this scheme, with multiple discharge branches, helps alleviate the conveying pressure on each branch. Given the common characteristics of pharmaceutical raw materials, such as easy hygroscopic agglomeration, strong adhesion to walls, and sensitivity to metal friction, reducing the conveying capacity of the discharge branches means shorter accumulation time, lower stacking pressure, and improved conveying efficiency. This minimizes existing problems like hygroscopic agglomeration and wall adhesion. Furthermore, a detachable vibrator is installed below each discharge pipe, corresponding to the distribution opening. This allows for rapid transfer of pharmaceutical raw materials from the distribution opening to the discharge pipe, preventing accumulation at the corresponding discharge pipe location. The low-frequency, high-amplitude excitation force generated by the vibrator is evenly transmitted along the pipe wall, actively breaking down powder bridging, rat holes, and wall retention layers, enabling auxiliary material flow. This helps to overcome the rigid dependence of traditional gravity conveying on installation inclination angle and minimum height difference threshold. The vibrator and discharge pipe are detachably connected, facilitating disassembly and cleaning.

[0013] Preferably, the discharge port is located on the floor of the room, and a transmission pipe section is provided between the discharge port and the discharge pipe. The transmission pipe section is used to connect the discharge port and the discharge pipe, and the material distribution structure is located between the transmission pipe section and the discharge pipe.

[0014] In this solution, the discharge port is set on the floor slab of the room, and a transmission pipe section is added between the discharge port and the discharge pipe. The height difference of the floor slab provides an initial drop, so that the material can obtain sufficient initial kinetic energy to enter the discharge pipe. At the same time, the material distribution structure is set between the transmission pipe section and the discharge pipe to ensure that the material maintains a concentrated flow state before entering the material distribution structure, avoiding the dispersion or deviation of the material before distribution, and improving the uniformity and reliability of material distribution.

[0015] Preferably, the transmission pipe section and the discharge port are detachably connected.

[0016] In this solution, the transmission pipe section and the discharge port are connected in a detachable manner, which allows the transmission pipe section to be quickly removed from the discharge port when cleaning, maintenance or replacement of the pipe is required, without the need to disassemble the entire feeding device. This significantly shortens maintenance downtime and reduces operation and maintenance costs. At the same time, it facilitates thorough cleaning of the inner wall of the pipe, meeting the high cleanliness requirements of pharmaceutical production.

[0017] Preferably, the transmission pipe section is set at an angle to the tray plane of the material distribution structure, with the angle ranging from 10° to 40°.

[0018] In this solution, by setting the transmission pipe section at an angle of 10° to 40° to the tray plane of the distribution structure, the material has a certain incident angle when entering the distribution structure, which avoids the material from vertically impacting the surface of the distribution structure and causing material splashing or dust dispersion. At the same time, this angle range can ensure that the material slides smoothly into the distribution opening under the action of gravity, which not only ensures the diversion efficiency, but also avoids the material flow rate being too fast due to the excessive angle, which would impact the distribution structure and cause wear.

[0019] Preferably, the discharge port of the transmission pipe section is gradually narrowed along the direction close to the material distribution structure.

[0020] In this scheme, the discharge port of the transmission pipe section adopts a tapering design, so that the cross-sectional area of ​​the flow channel gradually decreases and the material flow velocity gradually increases before the material enters the distribution structure, forming a converging flow effect. This ensures that the material enters the central area of ​​the distribution structure in a concentrated manner, avoiding the material from spreading or deviating at the entrance of the distribution structure, and further improving the distribution accuracy and the uniformity of material distribution in each branch.

[0021] Preferably, the material distribution structure further includes an inclined surface, which is disposed on the bottom surface of the material distribution structure. The inclined surface is inclined in a direction close to the material distribution opening. A flexible connector is disposed on the material distribution opening, one end of which is connected to the material distribution opening and extends into the discharge pipe.

[0022] In this design, a sloped surface is provided on the bottom surface of the material distribution structure, sloping towards the material distribution opening. Gravity guides the material towards the opening, eliminating dead zones and stagnant areas within the structure and ensuring complete material entry into each distribution branch. Simultaneously, a flexible connector is installed between the material distribution opening and the discharge pipe. This connector absorbs the impact energy generated by the discharge pipe's vibration, preventing structural damage due to rigid interfaces, and effectively isolates vibration transmission, preventing the material distribution structure from being affected by vibration and ensuring overall structural stability. Furthermore, the flexible connector can transfer some vibration energy to the material distribution opening area, further disrupting material bridging there. Its elastic deformation capacity compensates for installation deviations and thermal expansion / contraction between the discharge pipe and the material distribution structure, while ensuring a tight seal at the connection to prevent dust leakage.

[0023] Preferably, the material distribution structure further includes a sleeve, which is disposed around at least a portion of the flexible connector, and the sleeve is connected to the material distribution opening by a clamp.

[0024] In this solution, a sleeve is set around the flexible connector to provide radial support and limit the flexible connector, preventing excessive radial expansion or torsional deformation of the flexible connector during vibration, ensuring the stability of the cross-sectional shape of the material channel. At the same time, the sleeve is connected to the material distribution opening through a clamp, which is convenient to disassemble and install, and facilitates the replacement or cleaning of the flexible connector.

[0025] Preferably, the flexible connector is a cylindrical structure, and the inner diameter of the sleeve is larger than the outer diameter of the flexible connector.

[0026] In this design, the flexible connector adopts a cylindrical structure with a radial gap between it and the sleeve. This allows the flexible connector to freely generate radial micro-vibrations within the sleeve under vibration excitation. This vibration helps to further break down the material adhesion on the inner wall of the flexible connector. At the same time, the sleeve restricts the maximum radial displacement of the flexible connector to prevent excessive deformation from affecting the passage of materials. This ensures structural stability while guaranteeing the vibration-assisted flow effect.

[0027] Preferably, the material distribution structure further includes a sleeve, and the sleeve further includes a fastener. The fastener is disposed on the side of the sleeve facing the material distribution opening, and the fastener is in close contact with the protrusion on the surface of the material distribution opening to fix the flexible connector.

[0028] In this solution, a reliable mechanical locking structure is formed by the fasteners tightly fitting against the protrusions on the surface of the material distribution opening. This securely fixes the flexible connector to the material distribution opening, preventing it from loosening or falling off under long-term vibration conditions. This ensures the continuity and sealing of the material conveying channel. At the same time, this fastening method does not require drilling holes or applying additional clamping force to the flexible connector, avoiding damage to the flexible connector body and extending its service life.

[0029] Preferably, the angle between the feed pipe and the horizontal plane is in the range of 2° to 10°.

[0030] In this solution, by controlling the angle between the feed pipe and the horizontal plane within a very small range of 2° to 10°, the feed pipe can be arranged almost horizontally, which greatly reduces the requirements for installation space height and makes the equipment adaptable to scenarios such as pharmaceutical workshops with limited floor height. At the same time, with the flow-aiding effect of the vibrator, the material can still flow smoothly even at this very small inclination angle, overcoming the dependence of traditional gravity conveying on large-angle pipelines.

[0031] Preferably, the material distribution structure is fixed to the ceiling via a connecting structure.

[0032] In this solution, the material distribution structure is fixed to the ceiling via a connecting structure, and the ceiling is used as a load-bearing point to provide stable suspension support for the material distribution structure. This prevents the material distribution structure from sinking or shifting due to its own weight and material impact. At the same time, the ceiling fixing method does not occupy ground space, which facilitates personnel passage and equipment layout in the operating area below.

[0033] Preferably, a transmission pipe section is also provided between the discharge port and the feeding pipe, and the transmission pipe section is fixed to the ceiling through a connecting structure.

[0034] In this scheme, the transmission pipe section is also fixed to the ceiling through the connecting structure, so that the entire feeding device forms a stable suspension system from top to bottom. From the discharge port through the transmission pipe section and the material distribution structure to the feeding pipe, each section is reliably supported, avoiding pipe deformation or loosening of the connection due to the weight of the pipe and vibration, and ensuring the long-term stability of the material conveying channel.

[0035] Preferably, the vibrator is detachably connected to the feed pipe via a flange.

[0036] In this design, the vibrator is detachably connected to the feed pipe via a flange. The flange connection provides uniform contact pressure and a reliable force transmission path, ensuring that vibration energy is efficiently transmitted to the feed pipe wall. At the same time, the flange connection is easy to disassemble, allowing for quick separation of the vibrator from the feed pipe when it is necessary to replace the vibrator or clean and maintain the feed pipe, thus improving maintenance efficiency.

[0037] Preferably, the feeding pipe assembly further includes a plurality of hoppers, which are disposed at the outlet of the feeding pipe; the feeding device further includes a material level sensor, which is disposed in the hopper, and the material level sensor is disposed corresponding to the hopper, and the plurality of material level sensors are arranged in parallel.

[0038] In this solution, by setting up hoppers and corresponding level sensors at the outlets of each feed pipe, the material inventory in each branch hopper can be monitored in real time. The parallel setting of multiple level sensors allows the level status of any hopper to be independently detected and fed back to the control system. When a branch hopper is full, the upstream feeding rate can be adjusted in time or the feed can be switched to other branches, realizing intelligent material allocation and scheduling, avoiding hopper overflow or shortage, and improving production continuity.

[0039] Preferably, the feeding device further includes a support frame, which is disposed below the feeding pipe, the vibrator is disposed on the support frame, and a pulley assembly is disposed at the bottom of the support frame.

[0040] In this solution, a support frame is used to support the vibrator, and a pulley assembly is installed at the bottom of the support frame. This allows the vibrator assembly to move flexibly along the direction of the feed pipe, making it easy to adjust the installation position of the vibrator according to different feed pipe positions. At the same time, the pulley assembly allows the entire support frame along with the vibrator to be moved out of the working area when the vibrator needs to be replaced or maintained. Maintenance work can be completed without disassembling the feed pipe, significantly improving the maintainability of the equipment.

[0041] Preferably, a gasket is also provided inside the vibrator.

[0042] In this design, a shim is installed inside the vibrator. The shim can absorb some of the high-frequency vibration energy, reduce the wear of the vibrator's own components, and extend the service life of the vibrator.

[0043] A feeding control system is applied to the feeding device as described above. The feeding control system is connected to the material level sensor and the vibrator of the feeding device to control the material level sensor and the vibrator.

[0044] In this solution, by connecting the feeding control system with the material level sensor and vibrator, closed-loop automatic control of the feeding process is achieved: the control system receives the material level signal of each hopper in real time, and automatically adjusts the start / stop and vibration intensity of the vibrator according to the material level status. When the material level of a branch hopper is too high, the amplitude of the corresponding vibrator in that branch can be reduced or the vibration can be paused to reduce the material supply. Conversely, the vibration is increased to accelerate the material supply, thereby achieving dynamic balance distribution of materials in each branch, completely eliminating the tedious operation of manual inspection and adjustment, and improving the level of production automation and the accuracy of material management.

[0045] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0046] The positive and progressive effects of this invention are as follows:

[0047] By setting at least two independent feeding pipes in the feeding device and using the material distribution structure between the discharge port and the feeding pipe, the material from a single outlet is naturally divided into multiple non-interfering discharge branches, thus achieving synchronous and equal-pressure feeding at dual stations. Compared to a single discharge branch scheme, this scheme, with multiple discharge branches, helps alleviate the conveying pressure on each branch. Given the common characteristics of pharmaceutical raw materials, such as easy hygroscopic agglomeration, strong adhesion to walls, and sensitivity to metal friction, reducing the conveying capacity of the discharge branches means shorter accumulation time, lower stacking pressure, and improved conveying efficiency. This minimizes existing problems like hygroscopic agglomeration and wall adhesion. Furthermore, a detachable vibrator is installed below each discharge pipe to quickly transfer the pharmaceutical raw materials from the distribution opening to the discharge pipe, preventing accumulation at the corresponding discharge pipe location. The low-frequency, high-amplitude excitation force generated by the vibrator is evenly transmitted along the pipe wall, actively breaking down powder bridging, rat holes, and wall retention layers, allowing for auxiliary material flow. This helps to overcome the rigid dependence of traditional gravity conveying on installation inclination angle and minimum height difference threshold. The vibrator and discharge pipe are detachably connected, facilitating disassembly and cleaning. Attached Figure Description

Detailed Implementation

[0053] The present invention is further illustrated below by way of embodiments, but the invention is not limited to the scope of the embodiments described herein. Experimental methods in the following embodiments that do not specify specific conditions were performed according to conventional methods and conditions, or as selected according to the product instructions.

[0054] like Figure 1As shown, this embodiment provides a feeding device 100, which includes a feeding pipe assembly 1 connected to a discharge port 2. The feeding pipe assembly 1 includes a feeding pipe 11, and the number of feeding pipes 11 is at least two. The feeding device 100 also includes a material distribution structure 3 disposed between the discharge port 2 and the feeding pipe 11. The material distribution structure 3 is configured to divide the material output from the discharge port 2 into each feeding pipe 11. The material distribution structure 3 also includes a plurality of material distribution openings 31, which are provided corresponding to each feeding pipe 11. The feeding device 100 also includes a vibrator 4 disposed below the feeding pipe 11 and corresponding to the material distribution openings 31. The vibrator 4 is detachably connected to the feeding pipe 11.

[0055] In this embodiment, the single discharge port 2 is divided into multiple independent branches by the material distribution structure 3, realizing synchronous material supply at dual stations. This effectively reduces the conveying load of each branch, shortens the material accumulation time, and reduces the accumulation pressure, thereby alleviating problems such as easy moisture absorption and clumping of pharmaceutical raw materials and adhesion to the wall, and improving conveying efficiency. At the same time, each discharge pipe 11 is equipped with a detachable vibrator 4, which breaks down powder bridging and retention layers through low-frequency excitation force, assisting material flow, eliminating rigid dependence on installation tilt angle and height difference, and the detachable design facilitates cleaning and maintenance.

[0056] Specifically, the material distribution opening 31 of the material distribution structure 3 is located on the bottom surface of the material distribution structure 3. In this embodiment, there are two material discharge pipes 11, two material distribution openings 31, and two vibrators 4, each corresponding to one of the two material discharge pipes 11. The discharge port 2 is located on the floor slab of the room. A transmission pipe section 5 is also provided between the discharge port 2 and the material discharge pipe 11. The transmission pipe section 5 is used to connect the discharge port 2 and the material discharge pipe 11. The material distribution structure 3 is located between the transmission pipe section 5 and the material discharge pipe 11. The vibrator 4 and the material discharge pipe 11 are detachably connected by a flange 7. A connector is provided at the bottom end of the material discharge pipe 11 corresponding to the position of the vibrator 4. A connector is also provided on the vibrator 4. The connectors corresponding to the material discharge pipe 11 and the vibrator 4 are connected by a flange 7. The detachable connection between the vibrator 4 and the material discharge pipe 11 facilitates disassembly and cleaning.

[0057] In other embodiments, the number of feeding pipe 11 and distributing opening 31 may be more than two, the discharge port 2 may be set in other locations in the room, and the detachable connection structure between vibrator 4 and feeding pipe 11 may be in other forms, such as being directly connected to feeding pipe 11 by clamps without additional connecting parts, which will not be described in detail here.

[0058] Furthermore, the transmission pipe section 5 and the discharge port 2 are detachably connected via flange 7. This detachable connection allows for quick separation of the pipe section during cleaning, maintenance, or replacement without the need to disassemble the entire feeding device 100, significantly reducing downtime and maintenance costs. It also facilitates thorough cleaning of the inner wall of the pipe, fully meeting the stringent cleanliness requirements of pharmaceutical production. The transmission pipe section 5 is angled at 30° to the tray plane of the distribution structure 3, and the discharge port of the transmission pipe section 5 gradually narrows towards the distribution structure 3. This tapering structure of the discharge port of the transmission pipe section 5 gradually reduces the cross-sectional area of ​​the flow channel along the material flow direction, increasing the material velocity and creating a flow-gathering effect. This ensures that the material is concentrated in the central area of ​​the distribution structure 3, effectively preventing diffusion or flow deviation at the inlet, thereby improving the distribution accuracy and uniformity of the distribution in each branch. The transmission pipe section 5 and the discharge pipe 11 are composed of multiple pipe sections joined together via flange 7.

[0059] In other embodiments, the angle between the transmission pipe section 5 and the tray plane of the material distribution structure 3 can be other angles. The transmission pipe section 5 can also be detachably connected to the discharge port 2 through other structures such as snap-fit ​​structures, which will not be described in detail here.

[0060] The material distribution structure 3 also includes an inclined surface 32, which is located on the lower bottom surface of the material distribution structure 3. The inclined surface 32 slopes from the middle of the lower bottom surface of the material distribution structure 3 towards the material distribution opening 31. A flexible connector 311 is provided on the material distribution opening 31. The flexible connector 311 is a silicone sleeve. One end of the flexible connector 311 is connected to the material distribution opening 31 and extends into the feed pipe 11. The radial cross-sectional area of ​​the material distribution opening 31 is larger than the radial cross-sectional area of ​​the flexible connector 311 in its natural state, so that the flexible connector 311 is in an extended state when it is fitted onto the material distribution opening 31, allowing it to be firmly connected to the material distribution opening 31 and preventing it from falling off when subjected to the impact of feeding. In this embodiment, the inclined surface 32 on the lower bottom surface of the material distribution structure 3 guides the material to converge towards the material distribution opening 31, eliminating dead corners and stagnation, and ensuring that the material completely enters each feed branch. A flexible connector 311 is provided between the material distribution opening 31 and the discharge pipe 11. It can absorb vibration impact, isolate vibration from being transmitted upward, avoid rigid damage and resonance, and ensure structural stability. At the same time, it transmits some vibration to the opening to break up bridging, and relies on elastic deformation to compensate for installation deviation and thermal expansion and contraction, maintaining a seal to prevent leakage.

[0061] The material distribution structure 3 also includes a sleeve 312, which surrounds the material distribution opening 31. The sleeve 312 extends from the material distribution opening 31 in a direction close to the feed pipe 11 and surrounds the upper periphery of the flexible connector 311. The lower end of the sleeve 312 is adjacent to the feed pipe 11, and the lower end of the flexible connector 311 not surrounded by the sleeve 312 is located in the feed pipe 11. The sleeve 312 is connected to the material distribution opening 31 by a clamp 313. The flexible connector 311 has a cylindrical structure, and the inner diameter of the sleeve 312 is larger than the outer diameter of the flexible connector 311.

[0062] The material distribution structure 3 also includes a sleeve 312, and the sleeve 312 includes a fastener 314. The fastener 314 is located on the side of the sleeve 312 facing the material distribution opening 31. The fastener 314 is a horizontally extending lever. A spherical protrusion 315 is provided on the material distribution opening 31 corresponding to the position of the fastener 314. The protrusion 315 contacts the lever along the height direction. The fastener 314 and the protrusion 315 on the surface of the material distribution opening 31 are tightly fitted. The end of the fastener 314 that contacts the material distribution opening 31 is also spherical. A flexible connector 311 is inserted between the fastener 314 and the protrusion 315 to fix the flexible connector 311. In this embodiment, the tight fit between the fastener 314 and the protrusion 315 on the surface of the material distribution opening 31 forms a reliable mechanical locking structure, which firmly fixes the flexible connector 311 at the material distribution opening 31, effectively preventing loosening or falling off under long-term vibration conditions, and ensuring the continuity and sealing of the material conveying channel. This fastening method eliminates the need for drilling holes or applying additional clamping force to the flexible connector 311, thus avoiding damage to the main body and extending its service life.

[0063] In this embodiment, the angle between the discharge pipe 11 and the horizontal plane is 4°. The material distribution structure 3 is fixed to the ceiling via the connecting structure 6. The connecting structure 6 between the material distribution structure 3 and the ceiling also includes a flange 7. By setting the flange 7 here, the material distribution structure 3 can be disassembled relative to the ceiling, which facilitates the cleaning, replacement, and maintenance of the material distribution structure 3, and also facilitates the organization of materials in the material distribution structure 3. A transmission pipe section 5 is also provided between the discharge port 2 and the discharge pipe 11. The transmission pipe section 5 is fixed to the ceiling via the connecting structure 6. The connecting structure 6 between the transmission pipe section 5 and the ceiling includes a flange 7. By setting the flange 7 here, the transmission pipe section 5 can be disassembled relative to the ceiling, which facilitates the collection of materials in the transmission pipe section 5, as well as the cleaning, replacement, and maintenance of the pipe section. The connecting structure 6 for both the material distribution structure 3 and the transmission pipe section 5 is a hanger.

[0064] In other embodiments, the angle between the feeding pipe 11 and the horizontal plane can be other values, and the material distribution structure 3 may not be fixed to the ceiling, or it may be indirectly fixed to the ceiling through the transmission pipe section 5, which will not be elaborated here.

[0065] The feeding pipe assembly 1 also includes two hoppers 12, which are located at the outlet of the feeding pipe 11, and a collection bag is placed at the bottom of the hopper 12; the feeding device 100 also includes a material level sensor 13, which is located in the hopper 12, and the material level sensor 13 is set in relation to the hopper 12, and multiple material level sensors 13 are connected in parallel.

[0066] As shown in the figure, in this embodiment, the feeding device 100 further includes a support 8, which is located below the feeding pipe 11. Above the support 8 is a controller 83 for controlling the material level sensor 13, located below the vibrator 4. The vibrator 4 is mounted on the support 8. At the bottom of the support 8 are a pulley assembly 81 and a counterweight (not shown in the figure). The counterweight is used to keep the support 8 stable and prevent it from tipping over. A storage space 82 is also provided on the support 8. Furthermore, in this embodiment, a shim is provided inside the vibrator 4. The shim inside the vibrator 4 can absorb some of the high-frequency vibration energy, reducing wear on the components of the vibrator 4 and extending its service life.

[0067] This embodiment also provides a feeding control system, which is applied to the feeding device 100 as described above. The feeding control system is connected to the material level sensor 13 and the vibrator 4 of the feeding device 100 to control the material level sensor 13 and the vibrator 4.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
