Description

Technical Field

[0001] This invention relates to the field of filling machine technology, and specifically to a quantitative filling machine for mushrooms. Background Technology

[0002] Filling machines are a small category of packaging machines. Based on their filling principle, they can be categorized into atmospheric pressure filling machines, pressure filling machines, liquid filling machines, oil filling machines, paste filling machines, sauce filling machines, granular / slurry filling machines, powder filling machines, large-barrel water filling machines, and vacuum filling machines. Among these, sauce filling machines are suitable for filling viscous sauces containing particles and with high concentrations, such as chili sauce, bean paste, peanut butter, sesame paste, jam, and enoki mushroom sauce.

[0003] Existing sauce filling machines typically use a cylinder to drive a metering cylinder to fill the mixture (including dry ingredients and oils). When the cylinder extends, it pushes a piston towards one end of the metering cylinder, allowing the dry ingredients and oils to be discharged through the outlet pipe. When the cylinder retracts, it drives the piston towards the other end of the metering cylinder, allowing the dry ingredients and oils to enter the metering cylinder through the inlet pipe. Each piston movement completes one filling cycle, resulting in low production efficiency and difficulty in meeting actual production needs. Summary of the Invention

[0004] The purpose of this invention is to provide a quantitative filling machine for mushrooms, which solves the problem that existing quantitative filling machines for sauces have low production efficiency and cannot meet actual production needs.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A mushroom quantitative filling machine is provided, comprising a tangential valve, a first filling mechanism, and a second filling mechanism. The tangential valve is provided with an inlet, an outlet, a first valve port, and a second valve port. When the tangential valve is in a first open state, the inlet is connected to the first valve port, and the outlet is connected to the second valve port. When the tangential valve is in a second open state, the inlet is connected to the second valve port, and the outlet is connected to the first valve port. The first filling mechanism is connected to the first valve port, and the second filling mechanism is connected to the second valve port. When the tangential valve is in the first open state, the filling mechanism is connected to the second valve port. When the tangential valve is in the first open state, the first filling mechanism is in the feeding state and the second filling mechanism is in the discharging state; when the tangential valve is in the second open state, the first filling mechanism is in the discharging state and the second filling mechanism is in the feeding state; wherein, when the first filling mechanism has finished feeding and the second filling mechanism has finished discharging, the tangential valve switches from the first open state to the second open state; when the first filling mechanism has finished discharging and the second filling mechanism has finished feeding, the tangential valve switches from the second open state to the first open state.

[0007] A further embodiment is as follows: the first filling mechanism includes a metering barrel, a piston, and a driving component; the upper end of the metering barrel is connected to a first valve port; the piston is slidably disposed inside the metering barrel; the driving component is disposed below the metering barrel and connected to the piston; when the tangential valve is in a first open state, the driving component drives the piston to move along the direction from the upper end of the metering barrel to the lower end of the metering barrel, so as to draw the external mixture into the metering barrel through the feed port; wherein, the mixture includes dry material and oil; when the tangential valve is in a second open state, the driving component drives the piston to move along the direction from the lower end of the metering barrel to the upper end of the metering barrel in multiple steps, so as to sequentially transport the mixture in the metering barrel to multiple storage bottles through the discharge port.

[0008] A further improvement is that the mushroom quantitative filling machine also includes an oil compensation module; the discharge end of the oil compensation module is connected to the side of the tangential valve near the discharge port.

[0009] A further embodiment is as follows: the mushroom quantitative filling machine further includes a data acquisition module and a control module; the data acquisition module is located at the discharge port; the data acquisition module is used to acquire the filling parameters of the storage bottle at the discharge port in real time; wherein, the filling parameters include the measured volume and mass of the mixture; the control module is connected to the data acquisition module, the oil compensation module, and the drive component; when the tangential valve is in the second conducting state, the control module adjusts the working state of the drive component and the oil replenishment amount of the oil compensation module according to the reference parameters of the storage bottle and the filling parameters; wherein, the reference parameters include the reference values ​​of dry material mass, dry material density, oil mass, and oil density in the mixture.

[0010] A further proposed solution is as follows: the control module includes a first calculation unit, a first judgment unit, and a control unit; the first calculation unit calculates the measured mass values ​​of the dry material and the oil based on the dry material density reference value, the oil density reference value, the measured volume value, and the measured mass value; the first judgment unit determines whether the measured mass value of the dry material is equal to the dry material mass reference value; if so, the control unit generates a control command, and the oil compensation module responds to the control command to replenish oil according to the oil replenishment amount; the drive unit responds to the control command to stop the current working state; if not, the drive unit maintains the current working state, and the oil compensation module does not operate.

[0011] A further solution is that the control module also includes a second calculation unit; when the measured value of the dry material quality is equal to the reference value of the dry material quality, the second calculation unit calculates the amount of oil replenishment based on the reference value of the oil quality and the measured value of the oil quality.

[0012] A further solution is as follows: the feed end of the oil compensation module is connected to the side of the tangential valve near the discharge port; the control module also includes a third calculation unit and a second judgment unit; the third calculation unit calculates the dry-to-oil reference mass ratio and the dry-to-oil measured mass ratio based on the dry mass reference value, the oil mass reference value, the dry mass measured value, and the oil mass measured value; the second judgment unit determines whether the dry-to-oil measured mass ratio is equal to the dry-to-oil reference mass ratio; if the dry-to-oil measured mass ratio is less than the reference mass ratio, the second judgment unit determines whether the dry-to-oil measured mass ratio is equal to the reference mass ratio. If the dry-to-oil ratio is equal to the reference dry-to-oil ratio, the control unit generates an oil extraction command, and the oil compensation module responds to the oil extraction command to extract oil from the mixture flowing towards the outlet. If the measured dry-to-oil ratio is equal to the reference dry-to-oil ratio, the oil compensation module does not operate. If the measured dry-to-oil ratio is greater than the reference dry-to-oil ratio, the control unit generates an oil replenishment command, and the oil compensation module responds to the oil replenishment command to replenish oil into the mixture flowing towards the outlet.

[0013] A further improvement is that the feed end of the oil compensation module extends vertically, and a filter screen is provided at the end of the feed end of the oil compensation module.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] On the one hand, continuous filling is achieved by alternating feeding and discharging of the first and second filling mechanisms, aiming to reduce waiting time and significantly improve production efficiency. On the other hand, a tangential valve is used to synchronously control the feeding and discharging states of the first and second filling mechanisms, aiming to simplify the mechanical structure, facilitate equipment maintenance, and simplify operation.

[0024] The invention will now be further described with reference to the accompanying drawings.

[0025] Example 1: This embodiment provides a mushroom quantitative filling machine, such as... Figure 1 and Figure 2 As shown, the device includes a tangential valve 1, a first filling mechanism 6, and a second filling mechanism 7. The tangential valve 1 is provided with an inlet 2, an outlet 3, a first valve port 4, and a second valve port 5. When the tangential valve 1 is in a first conducting state, the inlet 2 is connected to the first valve port 4, and the outlet 3 is connected to the second valve port 5. When the tangential valve 1 is in a second conducting state, the inlet 2 is connected to the second valve port 5, and the outlet 3 is connected to the first valve port 4. The first filling mechanism 6 is connected to the first valve port 4. The second filling mechanism 7 is connected to the second valve port 5. When the tangential valve 1 is in a second conducting state, the inlet 2 is connected to the second valve port 5, and the outlet 3 is connected to the first valve port 4. The first filling mechanism 6 is connected to the first valve port 4. The second filling mechanism 7 is connected to the second valve port 5. When the tangential valve 1 is in a third conducting state, the first filling mechanism 6 is connected to the second valve port 5. When the tangential valve 1 is in the first conducting state, the first filling mechanism 6 is in the feeding state and the second filling mechanism 7 is in the discharging state; when the tangential valve 1 is in the second conducting state, the first filling mechanism 6 is in the discharging state and the second filling mechanism 7 is in the feeding state; wherein, when the first filling mechanism 6 has finished feeding and the second filling mechanism 7 has finished discharging, the tangential valve 1 switches from the first conducting state to the second conducting state; when the first filling mechanism 6 has finished discharging and the second filling mechanism 7 has finished feeding, the tangential valve 1 switches from the second conducting state to the first conducting state.

[0026] For example, during implementation, the tangential valve 1 is provided with an inlet 2, an outlet 3, a first valve port 4, and a second valve port 5. When the tangential valve 1 is switched to the first conducting state, the inlet 2 is connected to the first valve port 4, and the outlet 3 is connected to the second valve port 5; when the tangential valve 1 is switched to the second conducting state, the inlet 2 is connected to the second valve port 5, and the outlet 3 is connected to the first valve port 4.

[0027] The first filling mechanism 6 is connected to the first valve port 4 via flange bolts, welding, or other methods, and is in communication with the first valve port 4. That is, when the tangential valve 1 switches to the first state, the first filling mechanism 6 is connected to the inlet 2. At this time, the first filling mechanism 6 is in the feeding state, and external mixtures can enter the first filling mechanism 6 through the inlet 2. When the tangential valve 1 switches to the second state, the first filling mechanism 6 is connected to the outlet 3. At this time, the mixture inside the first filling mechanism 6 can be output through the outlet 3. The mixture refers to a mixture of dry ingredients and oils that form a sauce. The dry ingredients can be materials such as enoki mushrooms and shiitake mushrooms. The oil is chili oil.

[0028] The second filling mechanism 7 is connected to the second valve port 5 via flange bolts, welding, or other methods, and is in communication with the second valve port 5. That is, when the tangential valve 1 is switched to the first state, the second filling mechanism 7 is connected to the discharge port 3. At this time, the second filling mechanism 7 is in the discharge state, and the mixture inside the second filling mechanism 7 can be output through the discharge port 3. When the tangential valve 1 is switched to the second state, the second filling mechanism 7 is connected to the inlet port 2. At this time, external mixture can enter the second filling mechanism 7 through the inlet port 2.

[0029] During the filling process, when the tangential valve 1 is in the first open state, the external mixture enters the first filling mechanism 6 through the feed inlet 2, and the mixture in the second filling mechanism 7 is filled into the storage bottle through the discharge outlet 3. When the first filling mechanism 6 has finished feeding and the second filling mechanism 7 has finished discharging, the tangential valve 1 switches from the first open state to the second open state. At this time, the external mixture enters the second filling mechanism 7 through the feed inlet 2, and the mixture in the first filling mechanism 6 is filled into the storage bottle through the discharge outlet 3. Here, "feeding complete" means the mixture filling is finished, and "discharging complete" means the filled mixture has been completely output. On the one hand, by alternately feeding and discharging the first filling mechanism 6 and the second filling mechanism 7, continuous filling is achieved, aiming to reduce waiting time and significantly improve production efficiency. On the other hand, using a single tangential valve 1 to synchronously control the feeding and discharging states of the first filling mechanism 6 and the second filling mechanism 7 aims to simplify the mechanical structure, facilitate equipment maintenance, and simplify operation.

[0030] Example 2: To achieve the goal of filling the mixture in the first filling mechanism 6 into multiple storage bottles in multiple stages, based on Example 1 above, in this example, as... Figure 1As shown, the first filling mechanism 6 includes a metering tank 61, a piston 62, and a driving member 63; the upper end of the metering tank 61 is connected to the first valve port 4; the piston 62 is slidably disposed inside the metering tank 61; the driving member 63 is disposed below the metering tank 61 and is connected to the piston 62; when the tangential valve 1 is in the first open state, the driving member 63 drives the piston 62 to move along the upper end of the metering tank 61 towards the lower end of the metering tank 61, so as to draw the external mixture into the metering tank 61 through the feed port 2; wherein, the mixture includes dry material and oil; when the tangential valve 1 is in the second open state, the driving member 63 drives the piston 62 to move along the lower end of the metering tank 61 towards the upper end of the metering tank 61 in multiple steps, so as to sequentially transport the mixture in the metering tank 61 to multiple storage bottles through the discharge port 3.

[0031] For example, in the implementation process, the first filling mechanism 6 includes a metering tank 61, a piston 62, and a driving component 63. The upper end of the metering tank 61 is connected to the first valve port 4 by means of flange screwing, welding, or other methods, and the metering tank 61 is in communication with the first valve port 4.

[0032] The piston 62 is slidably disposed inside the metering container 61, and the piston 62 is sealed to the inner wall of the metering container 61. This creates a space between the upper end face of the piston 62 and the inner wall of the metering container 61 to accommodate the mixture.

[0033] The driving component 63 can be an electric telescopic rod, a hydraulic telescopic rod, or other telescopic devices with telescopic function. The driving component 63 is located below the metering container 61, and the output shaft of the driving component 63 is connected to the lower end of the piston 62 by welding, screwing, or other means, so that the piston 62 can slide up and down along the metering container 61 under the drive of the driving component 63.

[0034] During operation, when the tangential valve 1 is in the first open state, the metering tank 61, the first valve port 4, and the feed port 2 are connected in sequence. At this time, the driving component 63 drives the piston 62 to move from the upper end to the lower end of the metering tank 61, so as to form a space for accommodating the mixture between the upper end face of the piston 62 and the inner wall of the metering tank 61. At the same time, a negative pressure is generated in the metering tank 61 to draw the external mixture into the metering tank 61 through the feed port 2. After the metering tank 61 is filled with the mixture, the tangential valve 1 switches to the second open state, connecting the metering tank 61, the first valve port 4, and the discharge port 3 in sequence. At this time, the driving component 63 drives the piston 62 to move from the lower end to the upper end of the metering tank 61, so as to transport the mixture in the metering tank 61 to the storage bottle at the discharge port 3. In this process, as the driving component 63 drives the piston 62 to move from the lower end to the upper end of the metering cylinder 61, the piston 62 moves multiple times according to a preset stroke, which can realize the filling of multiple storage bottles. The aim is to improve the accuracy of each filling volume, thereby improving the consistency of the mixed material storage volume in each storage bottle, and thus improving the stability of product quality.

[0035] In a preferred embodiment, the structure of the second filling mechanism 7 is the same as that of the first filling mechanism 6.

[0036] Example 3: In actual use, because the density of dry matter is greater than that of oil, and the flowability of dry matter is less than that of oil, the dry matter in the mixture in the metering container 61 will gradually accumulate towards the bottom of the container. This causes the dry matter-to-oil ratio in the mixture within the metering container 61 to gradually increase from the top to the bottom of the container. In other words, the oil content gradually decreases and the dry matter content gradually increases from the top to the bottom of the container. Furthermore, after the mixture in the metering container 61 is filled into multiple storage bottles, the dry matter-to-oil ratio in each storage bottle gradually increases according to the order of filling, thus significantly reducing the consistency of the dry matter-to-oil ratio in each storage bottle. Therefore, based on Example 2 above, in this example, as... Figure 2 As shown, the mushroom quantitative filling machine also includes an oil compensation module 8; the discharge end of the oil compensation module 8 is connected to the side of the tangential valve 1 near the discharge port 3.

[0037] For example, in the implementation process, the above-mentioned mushroom quantitative filling machine also includes an oil compensation module 8. The discharge end of the oil compensation module 8 is connected to the side of the tangential valve 1 near the discharge port 3.

[0038] During operation, when the tangential valve 1 switches to the second conducting state and the drive unit 63 moves from the lower end to the upper end of the metering tank 61, the mixture in the metering tank 61 flows to the outlet 3 through the first valve port 4 and the tangential valve 1. At this time, the oil compensation module 8 starts synchronously and, before the mixture enters the storage bottle, adds an appropriate amount of oil to the mixture to be output through continuous compensation, pulse compensation, and proportional compensation. The oil compensation module 8 compensates for the oil loss caused by the settling of dry materials, aiming to improve the consistency of the dry material to oil ratio in the final mixture filled into each storage bottle, thereby improving the consistency of the sauce product in terms of taste, texture, and flavor.

[0039] Continuous compensation involves continuously injecting a small amount of oil during the discharge process. Pulse compensation involves intermittently injecting oil based on the number of injections or the degree of material settling. Proportional compensation involves dynamically adjusting the oil injection ratio based on the changing trend of dry matter content.

[0040] Example 4: To achieve more precise control over the fuel compensation module 8 during fuel compensation, based on Example 3 above, in this example, as... Figure 2 As shown, the mushroom quantitative filling machine further includes a data acquisition module 9 and a control module 10; the data acquisition module 9 is located at the discharge port 3; the data acquisition module 9 is used to acquire the filling parameters of the storage bottle at the discharge port 3 in real time; wherein, the filling parameters include the measured volume and mass of the mixture; the control module 10 is connected to the data acquisition module 9, the oil compensation module 8, and the drive component 63; when the tangential valve 1 is in the second conducting state, the control module 10 adjusts the working state of the drive component 63 and the oil replenishment amount of the oil compensation module 8 according to the reference parameters of the storage bottle and the filling parameters; wherein, the reference parameters include the dry material mass reference value, dry material density reference value, oil mass reference value, and oil density reference value in the mixture.

[0041] For example, in implementation, the above-mentioned mushroom quantitative filling machine also includes a data acquisition module 9 and a control module 10. The data acquisition module 9 is located at the discharge port 3, and the control module 10 is electrically connected to the data acquisition module 9, the oil compensation module 8, and the drive unit.

[0042] During operation, when the tangential valve 1 switches to the second conducting state and the driving component 63 drives the piston 62 to move from the lower end to the upper end of the metering tank 61, the mixture in the metering tank 61 flows to the outlet 3 through the first valve port 4 and the tangential valve 1. At this time, the acquisition module 9 acquires the filling parameters of the mixture in the storage bottle in real time. The filling parameters include the measured mass and volume of the mixture. The control module 10 acquires the reference parameters of the storage bottle and the filling parameters acquired by the acquisition module 9 in real time. The reference parameters of the storage bottle refer to the parameters of the mixture in the storage bottle when the mixture is in a preset state. These reference parameters include the reference values ​​of the dry material mass, dry material density, oil mass, and oil density in the storage bottle. Based on the difference between the reference parameters and the filling parameters, the control module 10 adjusts the speed or stroke length of the piston 62 driven by the driving component 63 to precisely control the amount filled each time. Simultaneously, the control module 10 controls the oil replenishment amount of the oil compensation module 8 based on the difference between the reference parameters and the filling parameters, ensuring that the final mixture filled into each storage bottle achieves the ideal dry / oil ratio. On one hand, real-time monitoring and automatic adjustment significantly reduce filling errors caused by changes in material properties or equipment wear, aiming to ensure the quality and consistency of each batch of products. On the other hand, it can flexibly meet the filling needs of different types and batches of sauces, aiming to eliminate the need for manual recalibration of equipment parameters, thereby improving the flexibility and efficiency of the production line. Furthermore, it allows for more precise control of the dry / oil ratio in each storage bottle, aiming to ensure consistent product quality in terms of taste and texture, thus contributing to enhanced brand image and market competitiveness.

[0043] Example 5: To achieve precise control of the dry material quality during the filling process, thereby facilitating oil compensation by the oil compensation module 8, this example builds upon Example 4. Figure 2 As shown, the control module 10 includes a first calculation unit 101, a first judgment unit 102, and a control unit 103. The first calculation unit 101 calculates the measured mass values ​​of the dry material and the oil based on the dry material density reference value, the oil density reference value, the measured volume value, and the measured mass value. The first judgment unit 102 determines whether the measured mass value of the dry material is equal to the dry material mass reference value. If so, the control unit 103 generates a control command, and the oil compensation module 8 responds to the control command to replenish oil according to the oil replenishment amount. The drive unit 63 responds to the control command to stop the current working state. If not, the drive unit 63 maintains the current working state, and the oil compensation module 8 does not operate.

[0044] For example, in the implementation process, the control module 10 includes a first calculation unit 101, a first judgment unit 102, and a control unit 103.

[0045] The first calculation unit 101 calculates the measured mass of the dry material and the oil in the storage bottle during the filling process, based on the reference values ​​of the dry material density and the oil density, as well as the measured volume and mass during the filling process. The calculation formulas for the measured mass of the dry material and the oil are shown in equation (1).

[0046] (1)

[0047] in, This is a reference value for dry density; This is the measured volume of the dry material. This is a reference value for oilseed density; This is the measured value of the oil density; This refers to the measured mass of the mixture inside the storage bottle during the filling process. This represents the measured volume of the mixture inside the storage bottle during the filling process. This represents the measured mass of dry material inside the storage bottle during the filling process. This represents the measured value of the oil mass inside the storage bottle during the filling process.

[0048] During the actual filling process, the mass of the dry material inside the storage bottle gradually increases. Therefore, when the first judgment unit 102 determines whether the measured mass of the dry material is equal to the reference mass of the dry material during the filling process, it only needs to consider two states: the measured mass of the dry material is less than the reference mass of the dry material, and the measured mass of the dry material is equal to the reference mass of the dry material.

[0049] During use, when the first judgment unit 102 determines that the measured dry material quality equals the reference dry material quality, the control unit 103 generates a control command. The drive unit 63, responding to the control command, stops its current operation, halting the movement of the piston 62 from the lower end to the upper end of the metering container 61. Simultaneously, the oil compensation module 8 responds to the control command to replenish oil according to the required amount. By using the measured dry material quality as the compensation trigger condition, oil compensation is ensured when the measured dry material quality equals the reference dry material quality. This aims to reduce the risk of uneven oil distribution or insufficient compensation during mid-filling, thereby reducing erroneous, over-compensated, or under-compensated situations and improving filling consistency.

[0050] When the first judgment unit 102 determines that the measured dry material mass is not equal to the dry material mass reference value, i.e., when the measured dry material mass is less than the dry material mass reference value, the control unit 103 does not operate. At this time, the drive component 63 continues to operate, driving the piston 62 to continue moving along the lower end of the metering container 61 towards the upper end of the metering container 61, thereby conveying more of the mixture in the metering container 61 to the storage bottle until the measured dry material mass equals the dry material mass reference value. Simultaneously, the oil compensation module 8 does not perform oil replenishment.

[0051] Example 6: To improve the accuracy of fuel replenishment, based on Example 5 above, in this example, as... Figure 2 As shown, the control module 10 further includes a second calculation unit 104; when the measured value of the dry material quality is equal to the reference value of the dry material quality, the second calculation unit 104 calculates the amount of oil replenishment based on the reference value of the oil quality and the measured value of the oil quality.

[0052] For example, during implementation, the control module 10 further includes a second calculation unit 104. When the measured dry material quality equals the dry material quality reference value, the second calculation unit 104 calculates the difference between the oil quantity reference value and the measured oil quantity quality based on the oil quantity quality reference value and the measured oil quantity quality. This difference is the amount of oil replenished. The aim is to achieve dynamic compensation based on real-time oil quantity quality deviations, thereby achieving precise oil replenishment and improving the consistency of the dry material / oil quantity ratio in each bottle of mixture.

[0053] Example 7: When piston 62 moves from the lower end to the upper end of metering cylinder 61, the mixture at the upper end contains more oil. Therefore, to reduce the risk that the measured dry matter mass of the mixture will not reach the reference dry matter mass after the mixture in the storage bottle reaches the filling volume in the storage bottle during the initial filling stage, based on Example 5 above, in this example, as... Figure 2As shown, the feed end of the oil compensation module 8 is connected to the side of the tangential valve 1 near the discharge port 3; the control module 10 also includes a third calculation unit 105 and a second judgment unit 106; the third calculation unit 105 calculates the dry-oil reference mass ratio and the dry-oil measured mass ratio based on the dry mass reference value, the oil mass reference value, the dry mass measured value, and the oil mass measured value; the second judgment unit 106 judges whether the dry-oil measured mass ratio is equal to the dry-oil reference mass ratio; if the dry-oil measured mass ratio is less than the reference mass ratio, the second judgment unit 106 judges whether the dry-oil measured mass ratio is equal to the reference mass ratio. If the dry-to-oil ratio is equal to the reference dry-to-oil ratio, the control unit 103 generates an oil extraction command, and the oil compensation module 8 responds to the oil extraction command to extract oil from the mixture flowing towards the outlet 3. If the measured dry-to-oil ratio is equal to the reference dry-to-oil ratio, the oil compensation module 8 does not operate. If the measured dry-to-oil ratio is greater than the reference dry-to-oil ratio, the control unit 103 generates an oil replenishment command, and the oil compensation module 8 responds to the oil replenishment command to replenish oil into the mixture flowing towards the outlet 3.

[0054] For example, during implementation, the feed end of the oil compensation module 8 is connected to the side of the tangential valve 1 near the discharge port 3. The control module 10 also includes a third calculation unit 105 and a second judgment unit 106.

[0055] When the tangential valve 1 switches to the second conducting state, and the driving component 63 drives the piston 62 to move from the lower end of the metering barrel 61 to the upper end of the metering barrel 61, the third calculation unit 105 calculates the reference mass ratio of dry material to oil based on the reference values ​​of dry material mass and oil mass; at the same time, the third calculation unit 105 calculates the measured mass ratio of dry material to oil based on the measured values ​​of dry material mass and oil mass.

[0056] The second judgment unit determines the ratio of the measured mass of dry feed and oil to the reference mass of dry feed and oil.

[0057] If the measured mass of some oil components is less than the reference mass ratio of dry and oil components, it indicates that too much oil or too little dry component has been added to the storage bottle. In this case, the oil compensation module 8 draws oil from the mixture flowing from the metering tank 61 to the outlet 3, reducing the amount of oil flowing into the storage bottle. This allows the mixture with less oil to be added to the storage bottle with more oil, thus balancing the mixture within the storage bottle. The aim is to achieve real-time dynamic adjustment of the dry / oil mass ratio in the mixture within the storage bottle during the filling process, thereby improving the consistency of the dry / oil ratio in each bottle of mixture.

[0058] If the measured mass of a certain amount of oil equals the reference mass ratio of dry oil, it indicates that the oil input into the storage bottle meets the reference mass. In this case, the oil compensation module 8 does not need to draw or replenish oil.

[0059] If the measured mass of a certain amount of oil exceeds the reference mass ratio of dry to oil, it indicates that too little oil or too much dry material has been added to the storage bottle. In this case, oil is added to the mixture at the outlet 3 via the oil compensation module 8 to increase the amount of oil flowing into the storage bottle. This allows the mixture with more oil to be fed into the storage bottle with less oil, thus balancing the mixture within the storage bottle. The aim is to achieve real-time dynamic adjustment of the dry to oil mass ratio in the mixture within the storage bottle during the filling process, thereby improving the consistency of the dry to oil ratio in each bottle of mixture.

[0060] In the specific implementation process, initially, when the driving component 63 drives the piston 62 to move from the lower end to the upper end of the metering barrel 61, the mixture located at the upper end of the metering barrel 61 enters the storage bottle through the discharge port 3. Since the mixture located at the upper end of the metering barrel 61 contains more oil, during the process of the mixture flowing from the metering barrel 61 to the discharge port 3, the oil compensation module 8 absorbs the oil from the mixture. This aims to adjust the dry material / oil ratio in the mixture in the storage bottle during the filling process, thereby reducing the risk of insufficient dry material quality in the storage bottle when the mixture in the storage bottle reaches the pre-filled volume due to the high oil content in the mixture near the upper end of the metering barrel 61.

[0061] During the middle stage when the driving component 63 drives the piston 62 to move from the lower end to the upper end of the metering barrel 61, the mixture located in the middle position of the metering barrel 61 enters the storage bottle through the discharge port 3. Since the dry matter to oil mass ratio in the mixture located in the middle position of the metering barrel 61 may be approximately the dry matter to oil reference mass ratio, the oil compensation module 8 does not need to suck up / replenish oil at this time, or it sucks up or replenishes oil in a small amount.

[0062] In the later stages of the process where the driving component 63 drives the piston 62 to move from the lower end to the upper end of the metering cylinder 61, the mixture located at the lower end of the metering cylinder 61 enters the storage bottle through the outlet 3. Since the mixture located in the middle of the metering cylinder 61 contains less oil, as the mixture flows from the metering cylinder 61 to the outlet 3, the oil compensation module 8 replenishes the initially absorbed oil into the mixture. This aims to adjust the dry / oil ratio in the mixture within the storage bottle during the filling process, thereby reducing the risk of insufficient oil content in the mixture near the lower end of the metering cylinder 61, ensuring the dry material quality in the storage bottle meets the reference standard. Simultaneously, it replenishes the initially absorbed oil into the later-filled storage bottle, thus reducing oil waste.

[0063] When the measured dry material mass in the storage bottle reaches the reference dry material mass, the oil compensation module 8 replenishes oil based on the difference between the oil mass reference value and the measured oil mass. This aims to achieve a secondary replenishment of oil, thereby adjusting the dry material / oil ratio in the mixture within the storage bottle to further improve the consistency of the dry material / oil ratio in each bottle of mixture.

[0064] Example 8: To reduce the risk of dry material in the mixture entering the oil compensation module 8 when it absorbs oil from the mixture, based on Example 7 above, in this example, as... Figure 2 As shown, the feed end of the oil compensation module 8 extends vertically, and a filter screen 11 is provided at the end of the feed end of the oil compensation module 8.

[0065] For example, during implementation, the feed end of the oil compensation module 8 extends vertically. This is intended to reduce the spontaneous inflow of oil into the oil compensation module 8 when it is not performing an oil suction action, thereby decreasing the amount of oil in the mixture and affecting the dry / oil ratio in the storage bottle.

[0066] A filter screen 11 is provided at the end of the feed end of the oil compensation module 8. The mesh of the filter screen 11 allows oil in the mixture to pass through, but does not allow dry material in the mixture to pass through. This is intended to facilitate the oil compensation module 8 to more accurately extract oil from the mixture. At the same time, the feed end of the oil compensation module 8 is vertically arranged. When the oil compensation module 8 performs the oil suction action, the dry material in the mixture can gradually move away from the end of the feed end of the oil compensation module 8 under its own gravity, thereby reducing the risk of dry material in the mixture clogging the filter screen 11 and affecting oil suction.

[0067] In a preferred embodiment, when the oil compensation module 8 is performing oil suction, its suction force is sufficient to absorb the oil near the feed end of the mixture, but insufficient to absorb the dry material in the mixture. This aims to reduce the risk of dry material adsorbing onto the filter screen 11, causing clogging and affecting oil suction. Furthermore, it aims to retain a portion of oil in the mixture, thus maintaining its fluidity and facilitating its flow into the storage bottle.
