Description

Technical Field

[0001] This utility model relates to the field of biscuit production technology, and in particular to a device for adjusting and adding quantitative amounts of shortening. Background Technology

[0002] In the industrial production of biscuits, especially shortbread, sandwich biscuits, or biscuits with specific textures, the uniform and quantitative addition of shortening or similar fat-based additives plays a crucial role in the final crispness, texture, flavor, and appearance of the biscuits.

[0003] Traditional methods of manually adding shortening or fat additives are not only labor-intensive and inefficient enough to meet the needs of large-scale biscuit production lines, but more importantly, manual operation is prone to inaccurate addition and uneven distribution, resulting in unstable quality of the same batch of biscuits. For example, some biscuits may be too oily or not crisp enough, affecting consumers' eating experience and brand reputation.

[0004] To meet the high-speed, continuous operation requirements of biscuit production lines and improve product quality consistency, some mechanized shortening / fat additive application devices have been developed in the prior art. These devices typically include a storage system and a preliminary output mechanism, such as applying the shortening to the biscuit dough or pre-formed biscuit blanks via extrusion pumps, roller coating, or simple dripping. However, in practical applications of biscuit production lines, these existing technologies suffer from uneven shortening distribution. Since the viscosity and flowability of the shortening used in biscuits are greatly affected by temperature and formulation, existing devices, when processing shortening in different states, may exhibit poor extrusion, stringing, uneven dripping, or the formation of coarse streaks or spots on the dough, rather than the ideal uniform thin layer or fine dotted distribution. This directly affects the crispness and final texture of the biscuits.

[0005] Therefore, it is necessary to improve the existing oil-adding technology to overcome its shortcomings. Summary of the Invention

[0006] To overcome the problems existing in related technologies, the purpose of this utility model is to provide a quantitative adjustment and addition control device for shortening. This device achieves quantitative output of shortening by setting a discharge roller with grooves or textures, and uses a filter disc installed through an elastic connector and connected to a vibration generator to filter and homogenize the shortening. Combined with a detection sensor for detecting the condition of the shortening on the filter disc and controlling the vibration generator to work selectively based on the detection signal, the device achieves automatic adjustment and control of the quantitative output and uniform addition of shortening, effectively solving the problems of easy clogging and uneven distribution of shortening, and overcoming the problems of inaccurate addition, uneven distribution, easy clogging, and poor adaptability to changes in the viscosity of shortening in the prior art.

[0007] A device for adjusting and adding flaky pastry, comprising a flaky pastry adjusting mechanism and a flaky pastry adding controller, wherein: The shortening quantitative adjustment mechanism includes: A grease storage unit is located above the material conveying path. The grease storage unit has a cavity for containing grease and at least one strip-shaped discharge port located at the lower part of the cavity. The quantitative output unit includes a discharge roller located at the strip-shaped discharge port. The surface of the discharge roller is provided with grooves or textures for carrying out the oil from the cavity of the storage unit used to hold the oil. The filtration and homogenization unit includes a filter disc located below the discharge roller. The filter disc is used to receive and filter the oil residue falling from the discharge roller. The filter disc is installed below the discharge roller via an elastic connector. The shortening adding controller includes: An output drive motor is connected to the discharge roller drive to drive the discharge roller to rotate and output the oil paste; A vibration generator is fixedly connected to the filter disc and is used to drive the filter disc to vibrate. A detection sensor is used to detect the oil content in the filter tray and output a detection signal; The vibration generator is electrically connected to the detection sensor, and the vibration generator operates selectively according to the output detection signal.

[0008] Furthermore, the oil quantity adjustment and addition control device also includes a cleaning unit, which includes at least one cleaning end that contacts the surface of the discharge roller, and the cleaning end is used to remove the adhering substances on the surface of the discharge roller.

[0009] The addition of a cleaning unit, whose cleaning end contacts the surface of the discharge roller, effectively removes grease or impurities adhering to the roller surface. This helps maintain the cleanliness of the grooves or textures of the discharge roller, ensuring the accuracy and stability of grease metering, preventing blockages or contamination caused by material accumulation, and further improving the reliability and hygiene of the equipment.

[0010] Furthermore, the cleaning end is a cleaning roller brush, which is arranged parallel to one side of the discharge roller, and the bristles of the cleaning roller brush are in contact with the surface of the discharge roller.

[0011] By having the brush bristles contact the surface of the discharge roller, oil residue and impurities in grooves or textures can be removed more flexibly and thoroughly. This roller-brush cleaning method is highly adaptable and has a good cleaning effect, providing a strong guarantee for the continuous and precise operation of the discharge roller.

[0012] Furthermore, the grease metering adjustment mechanism also includes a mounting frame, which is used to be fixedly installed above the material conveyor belt. The mounting frame is used to install the grease storage unit, the metering output unit, and the filtration and homogenization unit in sequence from top to bottom.

[0013] A mounting frame is provided to securely mount each functional unit and place it above the material conveyor belt. This modular and integrated installation method makes the oil-based quantitative adjustment mechanism and the addition controller compact and rationally laid out, facilitating installation, commissioning, and maintenance. It also allows for easy integration into existing biscuit or other food production lines, improving the equipment's versatility and integration.

[0014] Furthermore, the filter disc includes a four-sided frame and a bottom filter screen. The four-sided frame is installed on the mounting frame by elastic connectors and is suspended below the discharge roller. The bottom filter screen is horizontally arranged on the four-sided frame.

[0015] The structure of the filter disc (surrounding frame and bottom filter screen) and its installation on the mounting frame via elastic connectors, suspended below the discharge roller, give the filter disc excellent filtration and homogenization capabilities. Simultaneously, the elastic connection ensures that the vibration generated by the vibration generator is efficiently and evenly transmitted to the filter screen, maximizing the anti-clogging and auxiliary passage functions of vibration and ensuring smooth oil flow.

[0016] Furthermore, the elastic connector includes a steel wire rope body and connecting ends located at both ends of the steel wire rope body. One end of the elastic connector is connected to the filter disc, and the other end is connected to the mounting frame. The filter disc is connected to the mounting frame through multiple elastic connectors.

[0017] The flexible connector consists of a steel wire rope body and connecting ends, and multiple steel wire ropes connect the filter disc to the mounting frame. Using steel wire rope as the flexible connector provides excellent flexibility, strength, and durability, effectively isolating vibration from being transmitted to the frame while ensuring the stable suspension of the filter disc during vibration. Multiple connection points provide balanced support, further improving the operational stability and reliability of the filtration homogenization unit.

[0018] Furthermore, the oil-adding controller also includes a main controller, which is electrically connected to the detection sensor and the vibration generator. The main controller is used to receive the detection signal from the detection sensor and control the vibration intensity of the vibration generator.

[0019] A main controller is introduced and electrically connected to the detection sensors and vibration generator to control the vibration intensity of the generator based on the detection signals. This means the system can automatically adjust the vibration magnitude according to the actual situation of butter accumulation (feedback from the sensors), for example, using lower intensity vibration for slight accumulation and higher intensity vibration for severe accumulation. This refined intelligent control is more energy-efficient and effective than simple start-stop control, and can better adapt to different butter conditions and production conditions.

[0020] Furthermore, the main controller is also electrically connected to the output drive motor, and is used to receive the detection signal from the detection sensor and control the speed of the output drive motor.

[0021] The main controller is electrically connected to the output drive motor, enabling it to control the rotational speed of the discharge roller based on detection signals or other inputs (such as production line speed). This allows for dynamic adjustment of the quantitative output of the shortening, such as appropriately reducing the output speed when the filter plate shows a tendency to accumulate, or automatically adjusting the shortening supply according to changes in production line speed. This achieves more precise quantitative control and synchronization with the entire production line, greatly improving the level of automation and the consistency of product quality.

[0022] Furthermore, the detection sensor is a pressure sensor, a photoelectric sensor, an ultrasonic sensor, or a vision sensor.

[0023] It offers a variety of technology options, allowing users to choose the most suitable sensor type based on specific oil characteristics, detection requirements, and cost considerations, thereby improving the flexibility and applicability of the technology.

[0024] Furthermore, the detection sensor is a pressure sensor, which is located inside the filter disc and is used to detect the oil load on the filter disc.

[0025] The detection sensor is a pressure sensor located inside the filter disc to detect the grease load. The pressure sensor can directly measure the weight of the grease on the filter disc or the applied pressure, providing a direct and reliable means to determine the degree of grease accumulation or whether blockage has occurred. Feedback control based on the pressure signal can accurately and effectively trigger or adjust vibration, promptly resolving blockage problems and ensuring smooth operation of the filter disc.

[0026] The beneficial effects of this utility model are as follows: This utility model provides a device for quantitative adjustment and addition control of shortening. The shortening quantitative adjustment mechanism includes a shortening storage unit located above the material conveying path for holding shortening, a discharge roller with grooves or textures at the discharge port for quantitative output of shortening, and a filter disc installed below the discharge roller via an elastic connector for receiving and filtering shortening. The corresponding shortening addition controller includes an output drive motor for driving the discharge roller, a vibration generator connected to the filter disc, and a detection sensor installed inside the filter disc to detect the shortening status and electrically connected to the vibration generator. The discharge roller with grooves or textures achieves initial quantitative output of shortening. Combined with the filter disc installed via the elastic connector and driven by the vibration generator, the shortening is filtered and homogenized. The detection sensor monitors the shortening status on the filter disc in real time, and the operation of the vibration generator is controlled based on the detection signal. This overcomes the problems of inaccurate shortening addition, uneven distribution, and easy clogging in the prior art, achieving precise and uniform addition of shortening, improving production efficiency and product quality stability, and is particularly suitable for handling shortening with variable viscosity.

[0029] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0030] Example 1 like Figure 1 , Figure 2As shown, this embodiment provides a device for adjusting and adding oil paste quantitatively, including an oil paste quantitative adjustment mechanism and an oil paste addition controller, for accurately and uniformly adding oil paste in a biscuit production line.

[0031] The flaky quantitative adjustment mechanism includes a flaky storage unit 100, a quantitative output unit 300, and a filtration and homogenization unit 400.

[0032] The storage unit 100, which is a hopper structure, is located above the material conveying path (e.g., above the material conveyor belt 200 of a biscuit production line). The storage unit 100 has a cavity for containing a paste-like or semi-solid shortening, and one or more strip-shaped discharge ports extending along the material conveying direction are provided at the bottom of the cavity. The storage unit 100 is preferably made of food-grade stainless steel with a smooth surface to facilitate the flow and cleaning of the shortening.

[0033] The quantitative output unit 300 includes a discharge roller 310 located below the strip-shaped discharge port of the grease storage unit 100. The surface of the discharge roller 310 is provided with grooves or textures to carry out the grease from the cavity. The grooves or textures can be channels distributed along the roller's axial or helical direction, or fine textures formed by surface knurling. The discharge roller 310 is supported by bearings and driven by an output drive motor. The output amount of grease is adjusted by controlling the rotational speed of the discharge roller 310. The gap between the discharge port of the grease storage unit 100 and the surface of the discharge roller 310 can be adjusted according to the viscosity of the grease to ensure that the grease can smoothly enter the grooves or textures. To improve the quantitative output accuracy, a scraper in contact with the roller surface can be provided on one side of the discharge roller 310 to scrape off excess grease adhering to areas outside the grooves or textures, ensuring that only the grease within the grooves or textures is carried out.

[0034] The filtration and homogenization unit 400 includes a filter disc 410 located below the discharge roller 310. The filter disc 410 receives the oil residue falling from the surface of the discharge roller 310, filters and homogenizes it, removes particulate impurities, and makes the oil residue more evenly distributed. In this embodiment, the filter disc 410 preferably includes a surrounding frame 411 and a bottom filter screen 412 fixed to the lower part of the frame. The bottom filter screen 412 is preferably made of wire mesh or a perforated plate; the choice of mesh size or aperture depends on the fineness of the oil residue and the desired filtration and homogenization effect. The filter disc 410 is mounted (or suspended) on the mounting frame via an elastic connector 420 and is horizontally positioned directly below the discharge roller 310. The elastic connector 420 can be a steel wire rope, spring, rubber shock absorber, or other connector with a certain degree of elasticity.

[0035] The oil-adding controller includes an output drive motor, a vibration generator 500, a detection sensor, and a main controller.

[0036] The output drive motor is connected to the discharge roller 310 via a drive mechanism, such as gears, chains, or synchronous belts, to precisely control the rotational speed of the discharge roller 310, thereby achieving quantitative output of the grease. The output drive motor is preferably a servo motor or a stepper motor to achieve high-precision speed control.

[0037] The vibration generator 500 is fixedly connected to the filter disc 410, for example, mounted on the frame of the filter disc 410. The vibration generator 500 can be an electromagnetic vibrator, an eccentric wheel vibration motor, etc., used to drive the filter disc 410 to generate vibrations of a certain frequency and amplitude.

[0038] A detection sensor is used to detect the amount of grease within the filter disc 410 and output a detection signal. In this embodiment, the detection sensor is preferably a pressure sensor, located below the bottom filter screen 412 of the filter disc 410 or on the support structure, and is used to detect the load of grease on the filter disc 410 (i.e., the weight of accumulated grease or the applied pressure). When too much grease accumulates on the filter disc 410, the pressure sensor outputs a corresponding detection signal.

[0039] The vibration generator 500 is electrically connected to the detection sensor, and operates selectively based on the detection signal. Specifically, when the detection sensor detects that the oil slurry load on the filter disc 410 has reached a preset threshold and outputs a corresponding detection signal, the controller issues a command to the vibration generator 500 to start or increase vibration, thereby helping the oil slurry pass through the bottom filter screen 412 more quickly and preventing clogging. When the oil slurry load drops below the threshold, the vibration generator 500 stops vibrating or reduces the vibration intensity.

[0040] This embodiment also includes a mounting frame for fixed installation above the material conveyor belt 200. The mounting frame sequentially mounts the storage unit 100, the quantitative output unit 300, and the filtration and homogenization unit 400 from top to bottom. The filter disc 410 of the filtration and homogenization unit 400 is mounted on the mounting frame via an elastic connector 420 and suspended below the discharge roller 310, allowing the filter disc 410 to vibrate freely.

[0041] The cleaning unit includes at least one cleaning end that contacts the surface of the discharge roller 310, used to remove grease or impurities adhering to the surface of the discharge roller 310. In this embodiment, the cleaning end is preferably a cleaning brush 600, which is arranged parallel to one side of the discharge roller 310. The bristles of the cleaning brush 600 contact the surface of the discharge roller 310, and the adhering substances on the roller surface are removed by the rotation or oscillation of the bristles.

[0042] In this embodiment, the elastic connector 420 is composed of a steel wire rope body 421 and connecting ends located at both ends of the steel wire rope body 421. One end of the elastic connector 420 is connected to the surrounding frame 411 of the filter disc 410 via the connecting end, and the other end is connected to a support point on the mounting frame via the connecting end. To ensure that the filter disc 410 is subjected to uniform force and can vibrate stably, the filter disc 410 is connected to the mounting frame through multiple (e.g., one at each of the four corners, or more) elastic connectors 420, forming a suspended installation. The length and diameter of the steel wire rope can be selected according to the weight of the filter disc 410 and the required vibration characteristics. The connecting ends of the steel wire rope can be ring connectors, U-bolts, etc., and are connected to the filter disc 410 frame and the mounting frame by fasteners such as screws and nuts. This multi-point steel wire rope suspension method provides necessary elastic support and ensures that the filter disc 410 is not prone to displacement or tilting during vibration, which is conducive to the uniform falling of the oil.

[0043] In this embodiment, to avoid oil splashing, baffles are provided on both sides of the material conveyor belt 200 and below the discharge rollers 310, and fixed on the mounting frame. The shape of the baffles is first vertically downward and then bent inward.

[0044] This embodiment discloses a device for quantitative adjustment and addition control of shortening. The embodiment uses a discharge roller 310 with grooves or textures on its surface to achieve quantitative output of shortening, and a filter disc 410 suspended by an elastic connector 420 (e.g., a steel wire rope) for filtration, homogenization, and collection. A pressure sensor detects the shortening load on the filter disc 410, and intelligently controls a vibration generator 500 to start working based on the detection signal, achieving automatic anti-clogging. A cleaning roller brush 600 cleans the discharge roller 310 to ensure quantitative accuracy. This solution has a compact and practical structure, enabling precise and uniform addition of shortening and effective automatic anti-clogging function, improving equipment stability and production efficiency.

[0045] Example 2 like Figure 1 , Figure 2 As shown, this embodiment provides a device for adjusting and adding oil paste quantitatively, including an oil paste quantitative adjustment mechanism and an oil paste addition controller, for accurately and uniformly adding oil paste in a biscuit production line.

[0046] The oil-based quantitative adjustment mechanism includes an oil storage unit 100, a quantitative output unit 300, and a filtration and homogenization unit 400.

[0047] The storage unit 100 is a hopper with a conical bottom, converging at a strip-shaped outlet. To ensure smooth discharge of the shortening from the hopper, especially when handling shortening with high viscosity or prone to clumping, the storage unit 100 is equipped with a spiral feeder or stirring blades inside its cavity. These devices rotate slowly under the drive of a motor, continuously agitating and pushing the shortening towards the strip-shaped outlet, preventing bridging or dead zones within the hopper and ensuring a continuous and stable supply of shortening. The storage unit 100 is made of easy-to-clean materials that meet food hygiene standards, such as stainless steel.

[0048] The quantitative output unit 300 includes a discharge roller 310 located below the strip-shaped discharge port of the grease storage unit 100. Unlike Embodiment 1, the surface of the discharge roller 310 in this embodiment has an array of distributed pits or discrete volumetric units, such as small pits with hemispherical or conical cross-sections, or square or hexagonal grooves. The size and density of these pits or volumetric units need to be adjusted according to the actual flow rate requirements, and each unit can hold a relatively fixed volume of grease. When the discharge roller 310 rotates, these pits or units filled with grease are carried out from below the grease storage unit 100, and the grease falls onto the filtration and homogenization unit 400 below by its own gravity or through subsequent means. The discharge roller 310 is driven to rotate by a drive motor, and its rotational speed directly determines the volume of grease output per unit time, thereby achieving high-precision quantitative output.

[0049] The filtration and homogenization unit 400 includes a filter disc 410 located below the discharge roller 310. In this embodiment, the filter disc 410 is a monolithic metal sieve or polymer filter plate with a precision micropore array. The diameter of these micropores is much smaller than the impurity particles that may be present in the oil, and also causes the passing oil to form finer droplets or filaments, thereby achieving the functions of filtration and homogenization. The filter disc 410 is mounted horizontally on the supporting structure or mounting frame below via an elastic connector 420.

[0050] The oil-adding controller includes an output drive motor, a vibration generator 500, a detection sensor, and a main controller.

[0051] The output drive motor is connected to the discharge roller 310 to precisely control the rotation speed of the discharge roller 310, thereby controlling the output flow rate of the grease.

[0052] The vibration generator 500 is fixedly connected to the filter disc 410 and is used to drive the filter disc 410 to vibrate. In this embodiment, the vibration generator 500 can be multiple small piezoelectric ceramic actuators, which are directly attached or embedded in the bottom of the filter disc 410. By independently or collaboratively controlling the electrical signals of these piezoelectric ceramic actuators, local vibration or more complex vibration modes in different areas of the filter disc 410 can be achieved to more effectively solve the clogging problem in specific locations.

[0053] The detection sensor is used to detect the grease buildup on the filter disc 410 and outputs a detection signal. Unlike the pressure sensor used in Embodiment 1, the detection sensor in this embodiment is a plurality of ultrasonic sensors, which are distributed and installed above the filter disc 410. The thickness or accumulation height of the grease buildup on the filter disc 410 is determined by measuring the reflection time or attenuation of the ultrasonic signal.

[0054] The vibration generator 500 is electrically connected to the detection sensor and operates selectively based on the detection signal. The main controller receives and processes the detection signals from the vision sensor or ultrasonic sensor, and determines the working state of the filter disc 410 according to a preset correspondence curve. When excessive oil buildup, uneven distribution, or signs of blockage are detected on the filter disc 410, the main controller sends a control command to the vibration generator 500 to start or adjust the vibration mode and intensity. For example, if the ultrasonic sensor in a certain area detects severe buildup in that area, the piezoelectric ceramic actuator below that area amplifies the vibration.

[0055] This embodiment also includes a mounting frame for fixing and supporting the aforementioned units.

[0056] The cleaning unit includes at least one cleaning end that contacts the surface of the discharge roller 310 for removing adhering substances from the surface of the discharge roller 310. In this embodiment, the cleaning unit can employ a scraper or brush in conjunction with pneumatic / electric drive. The scraper is made of an elastic material, and its blade is in close contact with the surface of the discharge roller 310, scraping away residue from the roller through linear reciprocating or oscillating motion. The brush can be a rotary brush or a reciprocating brush, with bristles contacting the roller surface for cleaning. A drive device (e.g., a small cylinder or motor) controls the movement of the scraper or brush to achieve effective cleaning.

[0057] In this embodiment, the filter disc 410 is mounted on the mounting frame via elastic connectors 420. The elastic connectors 420 can be multiple helical compression springs or rubber damping pads. The surrounding frame 411 of the filter disc 410 is secured above these helical springs or rubber damping pads by bolts or clips, and these springs or damping pads are then fixed to the mounting frame. This mounting method provides the necessary elastic support, allowing the filter disc 410 to vibrate effectively under the action of the vibration generator 500, while avoiding excessive transmission of vibration to the mounting frame and the entire device.

[0058] The working process of the shortening quantitative adjustment and addition control device in this embodiment is as follows: First, the paste or semi-solid shortening is added to the cavity of the shortening storage unit 100. The spiral feeder or stirring blades inside the shortening storage unit 100 work continuously or intermittently to assist in conveying the shortening to the strip-shaped discharge port.

[0059] The output drive motor drives the discharge roller 310 to rotate at a set speed. When the pits or discrete volume units on the surface of the discharge roller 310 pass below the strip-shaped discharge port of the grease storage unit 100, the grease is filled into these pits or units. During the rotation of the roller, the edge of the discharge port of the grease storage unit 100 or the auxiliary scraper scrapes away excess grease, ensuring that the amount of grease carried by each pit or unit is relatively constant, thus achieving preliminary quantitative measurement of grease.

[0060] When the discharge roller 310 carrying the oil paste rotates above the filtration homogenizing unit 400, the oil paste in the pit or unit falls onto the filter plate 410 below due to gravity or centrifugal force.

[0061] The shortening diffuses onto the filter plate 410 and passes through precision micropores. The microporous structure of the filter plate 410 filters the shortening, removing fine impurities and dispersing it into smaller units as it passes through, thus achieving homogenization and forming a more uniform stream or droplets of shortening. The homogenized shortening then falls onto the biscuit dough or biscuit base below.

[0062] During the process of the oil paste passing through the filter plate 410, the oil paste may accumulate in the micropores of the filter plate 410 due to the viscosity of the oil paste, temperature changes, or a small amount of air entrained in it, and may even cause local blockage.

[0063] At this time, a visual sensor or ultrasonic sensor installed above the filter disc 410 monitors the state of the grease on the surface of the filter disc 410 in real time. The ultrasonic sensor measures the accumulation height of the grease to determine the uniformity of distribution, the degree of accumulation, or the presence of blockage areas.

[0064] The detection sensor converts the detected grease levels into a detection signal and outputs it to the main controller. The main controller processes this detection signal according to preset control logic. When the detection signal indicates that the grease accumulation has reached a threshold requiring intervention (e.g., the ultrasonic sensor detects that the grease level is too high), the main controller immediately issues a command to control the vibration generator 500 to start vibration or adjust the vibration intensity.

[0065] A vibration generator 500 (such as a piezoelectric ceramic actuator array) connected to the filter disc 410 generates vibrations under the drive of the main controller. Since the filter disc 410 is mounted via elastic connectors 420, these vibrations are effectively transmitted to the entire surface of the filter disc 410, causing oil deposits in the micropores to loosen, flow, and pass through the filter disc 410 more quickly, thereby clearing or alleviating clogging. The vibration intensity and pattern can be dynamically adjusted based on feedback from detection signals to achieve optimal anti-clogging performance.

[0066] At the same time, the main controller can also adjust the speed of the output drive motor according to the signal of the detection sensor. For example, when the filter disc 410 is severely clogged, the speed of the discharge roller 310 can be appropriately reduced to reduce the supply of upstream grease and give the filter disc 410 more time to process it.

[0067] In addition, the cleaning unit operates periodically or as needed, with a scraper or brush cleaning the pits or volumetric units on the surface of the discharge roller 310 to remove any oil residue or impurities that may remain there, ensuring that the metering accuracy of the discharge roller 310 is not affected.

[0068] This embodiment provides another solution for the grease metering and addition control device. The grease storage unit 100 is equipped with a stirring and feeding device to improve grease flowability; the discharge roller 310 uses an array of pits to achieve more precise volumetric metering; the filter plate 410 is an integral precision microporous plate; the vibration generator 500 consists of multiple piezoelectric ceramic actuators, enabling localized or fine vibration control; the detection sensor uses distributed ultrasonic sensors to monitor the grease accumulation height and distribution. Intelligent control of the piezoelectric ceramic array vibration via ultrasonic signals achieves refined anti-clogging. A scraper / brush is used to clean the roller. This solution offers more flexible and diverse structural options, better adapting to grease of different viscosities, and achieving more intelligent and targeted anti-clogging and metering control, enhancing the applicability and performance of the equipment.
