Description

Technical Field

[0001] The present application relates to the technical field of material processing, and in particular to a material discharge control method of a feeder and a feeder. Background Art

[0002] In the field of metal powder processing, feeders are a commonly used material conveying equipment, mainly used for feeding, metering and mixing powder raw materials in the manufacturing process. Traditional feeders include worm feeders or gas conveying feeders, which are widely used in material conveying in various industries, such as food, chemicals, building materials, medicine, etc.

[0003] However, as the particle size of metal powder becomes smaller and smaller, the ultra-fine particle size metal powder is prone to agglomeration and blockage during the feeding process of the feeder, which greatly affects the processing efficiency and reduces production capacity. Summary of the invention

[0004] The present application provides a feeder and a material discharging control method thereof, which can reduce the occurrence of material blockage and agglomeration by controlling the different rotation speeds of the first blade group and the second blade group, and can also accurately control the material discharging amount, thereby greatly improving material processing efficiency and increasing production capacity.

[0005] In order to achieve the above objectives, the main technical solutions adopted in this application include: In the first aspect, an embodiment of the present application provides a discharge control method of a feeder, the feeder comprising a feeding barrel defining a accommodating chamber, and a stirring portion arranged in the accommodating chamber, wherein along the vertical direction, the upper end and the lower end of the feeding barrel respectively have a first feed port and a first discharge port, the first feed port and the first discharge port are both connected to the accommodating chamber, the stirring portion comprises a first blade group and a second blade group arranged adjacent to each other, the first blade group and the second blade group are spaced apart in the vertical direction, and the first blade group is closer to the first feed port than the second blade group, the distance between the first blade group and the first feed port is greater than the distance between the first blade group and the first discharge port, the rotation speed of the first blade group is greater than the rotation speed of the second blade group, and the discharge control method comprises: in response to a discharge instruction, determining the discharge amount per unit time; and controlling the first blade group and the second blade group to perform stirring work at different rotation speeds according to the discharge amount per unit time.

[0006] According to the discharge control method of the feeder proposed in the embodiment of the present application, based on the upper and lower settings of the first blade group and the second blade group and the different rotation speeds, and by controlling the discharge amount per unit time to control the first blade group and the second blade group to stir at different rotation speeds, it can not only reduce the occurrence of material blockage and agglomeration, but also accurately control the discharge amount, greatly improving the material processing efficiency. Among them, since the first blade group is close to the feed port and has a faster rotation speed, it can quickly disperse the newly added material into the entire accommodating chamber, which helps to avoid the accumulation of materials near the feed port and ensure the uniform distribution of materials in the feed barrel. At the same time, the faster rotation speed means that the first blade group can generate a stronger stirring force, thereby more effectively dispersing the material. As the material moves toward the second blade group, it has been dispersed to a certain extent. At this time, the second blade group continues to stir at a slower rotation speed, which can further refine the dispersion effect and prevent the stirring from being too fast to affect the efficiency of material discharge. Not only is the discharge accurate, but the production capacity is also improved.

[0007] Furthermore, the first blade group and the second blade group adopt different rotation speeds to produce different fluid mechanics effects, thereby forming a more complex flow pattern in the containing chamber. This complex flow pattern helps to better disperse the material. At the same time, different rotation speeds can also help adjust the flow direction of the material, ensuring that the material can be discharged smoothly from the discharge port, reducing the chance of material blockage or retention.

[0008] Optionally, in some embodiments of the present application, the blades in the first blade group are extended and retracted in the horizontal direction, wherein, before controlling the first blade group and the second blade group to stir at different speeds according to the discharge amount in the unit time, the discharge control method further includes: determining a target blade length according to the discharge amount in the unit time; and controlling the blades in the first blade group to extend and retract in the horizontal direction according to the target blade length.

[0009] By arranging the blades in the first blade group to be retractable in the horizontal direction, the present application can control the horizontal length of the blades in the first blade group to match the discharge volume per unit time, thereby achieving precise matching of stirring efficiency and discharge volume, which can not only improve the discharge efficiency but also further avoid the occurrence of material blockage and agglomeration.

[0010] Optionally, in some embodiments of the present application, the first blade group and the second blade group are controlled to perform stirring work at different speeds according to the discharge amount in the unit time, including: determining the target speed of the first blade group according to the discharge amount in the unit time, and determining the target speed of the second blade group according to the target speed of the first blade group and the speed relationship between the first blade group and the second blade group; controlling the first blade group to perform stirring work according to the target speed of the first blade group, and controlling the second blade group to perform stirring work according to the target speed of the second blade group.

[0011] Furthermore, the rotational speed relationship between the first blade group and the second blade group satisfies the following relationship: 0.5n1≤n2≤0.9n1 Wherein, n1 is the rotation speed of the first blade group, and n2 is the rotation speed of the second blade group.

[0012] In the above scheme, since the rotation speed ratio of the first blade group and the second blade group satisfies the above range, on the one hand, the stirring effect can be improved by different rotation speeds, which helps to adjust the flow direction of the material and reduce the probability of material agglomeration and blockage; on the other hand, it can ensure that the rotation speed difference between the first blade group and the second blade group is not too large, which helps to balance the fluid dynamics effect in the accommodating chamber, avoid affecting the uniform flow of the material, and reduce the probability of uneven material distribution or uneven stirring.

[0013] Optionally, in some embodiments of the present application, the number of blades in the first blade group is less than the number of blades in the second blade group.

[0014] In the above scheme, the first blade group is close to the first feed port and has fewer blades, so that the material is subjected to less shear force and impact force when it first enters the containing chamber. At the same time, the smaller number of blades also helps the material to pass through the first feed port more quickly and be dispersed into the entire containing chamber; the second blade group has more blades and can provide stronger stirring force and shear force. This design helps to disperse the material more fully and improve stirring efficiency and material uniformity.

[0015] In the second aspect, the embodiment of the present application also provides a feeding machine, including: a feeding barrel, which is defined by a accommodating chamber, and along the vertical direction, the upper end and the lower end of the feeding barrel are respectively provided with a first feed port and a first discharge port, and the first feed port and the first discharge port are both connected to the accommodating chamber; a stirring part, which is arranged in the accommodating chamber, and the stirring part includes a first blade group and a second blade group which are adjacently arranged, and the first blade group and the second blade group are arranged at intervals in the vertical direction, and the first blade group is closer to the first feed port than the second blade group, the distance between the first blade group and the first feed port is greater than the distance between the first blade group and the first discharge port, and the rotation speed of the first blade group is greater than the rotation speed of the second blade group; a control part, and the control part is constructed to determine the discharge amount per unit time in response to a discharge instruction, and control the first blade group and the second blade group to perform stirring work at different rotation speeds according to the discharge amount per unit time.

[0016] According to the feeder of the embodiment of the present application, since the first blade group and the second blade group are arranged up and down and have different rotation speeds, the control unit controls the first blade group and the second blade group to stir at different rotation speeds based on the discharge volume per unit time, which can not only reduce the occurrence of material blockage and agglomeration, but also accurately control the discharge volume, greatly improving the material processing efficiency. Among them, it is the first blade group that is close to the feed port and has a faster rotation speed, which can quickly disperse the newly added material into the entire accommodating chamber, which helps to avoid the accumulation of materials near the feed port and ensure the uniform distribution of materials in the feeding barrel. At the same time, the faster rotation speed means that the first blade group can generate a stronger stirring force, thereby more effectively dispersing the material. As the material moves to the second blade group, it has been dispersed to a certain extent. At this time, the second blade group continues to stir at a slower rotation speed, which can further refine the dispersion effect and prevent the stirring from being too fast to affect the efficiency of material discharge. Not only is the discharge accurate, but the production capacity is also improved.

[0017] Furthermore, the first blade group and the second blade group adopt different rotation speeds to produce different fluid mechanics effects, thereby forming a more complex flow pattern in the containing chamber. This complex flow pattern helps to better disperse the material. At the same time, different rotation speeds can also help adjust the flow direction of the material, ensuring that the material can be discharged smoothly from the discharge port, reducing the chance of material blockage or retention.

[0018] Optionally, in some embodiments of the present application, the blades in the first blade group are extended and retracted in the horizontal direction, and the control unit is also constructed to determine the target blade length according to the discharge amount per unit time before controlling the first blade group and the second blade group to perform stirring at different speeds according to the discharge amount per unit time, and control the blades in the first blade group to extend and retract in the horizontal direction according to the target blade length.

[0019] Since the blades in the first blade group are retractable in the horizontal direction, the control unit can control the horizontal length of the blades in the first blade group to match the discharge volume per unit time, thereby achieving precise matching of stirring efficiency and discharge, which can not only improve the discharge efficiency, but also further avoid the occurrence of material blockage and agglomeration.

[0020] Optionally, in some embodiments of the present application, the number of blades in the first blade group is less than the number of blades in the second blade group.

[0021] In the above scheme, the first blade group is close to the first feed port and has fewer blades, so that the material is subjected to less shear force and impact force when it first enters the containing chamber. At the same time, the smaller number of blades also helps the material to pass through the first feed port more quickly and be dispersed into the entire containing chamber; the second blade group has more blades and can provide stronger stirring force and shear force. This design helps to disperse the material more fully and improve stirring efficiency and material uniformity.

[0022] Optionally, in some embodiments of the present application, the control unit includes: a speed determination unit, used to determine the target speed of the first blade group according to the discharge amount in the unit time, and determine the target speed of the second blade group according to the target speed of the first blade group and the speed relationship between the first blade group and the second blade group; a drive control unit, used to control the first blade group to perform stirring according to the target speed of the first blade group, and control the second blade group to perform stirring according to the target speed of the second blade group.

[0023] Furthermore, the rotational speed relationship between the first blade group and the second blade group satisfies the following relationship: 0.5n1≤n2≤0.9n1 Wherein, n1 is the rotation speed of the first blade group, and n2 is the rotation speed of the second blade group.

[0024] In the above scheme, since the rotation speed ratio of the first blade group and the second blade group satisfies the above range, on the one hand, the stirring effect can be improved by different rotation speeds, which helps to adjust the flow direction of the material and reduce the probability of material agglomeration and blockage; on the other hand, it can ensure that the rotation speed difference between the first blade group and the second blade group is not too large, which helps to balance the fluid dynamics effect in the accommodating chamber, avoid affecting the uniform flow of the material, and reduce the probability of uneven material distribution or uneven stirring.

[0034] As an example, the feeder includes a worm feeder and a gas conveying feeder. A worm feeder is a feeder based on spiral motion, consisting of a worm and a pipe, wherein the worm is a spiral-shaped device and the pipe is a channel for conveying materials to the destination.

[0035] In the food industry, worm feeders can be used to convey powdered, granular and bulk materials, such as flour, beans, candy, etc. In the chemical industry, worm feeders can be used to convey chemical raw materials and powder particles. In the building materials industry, worm feeders can be used to convey cement, lime, fly ash and other materials. In the pharmaceutical industry, worm feeders can be used to convey pharmaceutical raw materials and powder particles.

[0036] A gas conveying feeder is a feeder that uses the energy of airflow to transport granular materials along the direction of airflow in a closed pipe based on the principle of pneumatic conveying. Gas conveying feeders can also be divided into suction type, pressure type and mixed type according to the speed and pressure of the airflow.

[0037] As an example, the powder material includes, but is not limited to, fine powder or ultrafine powder of metals, alloys, ceramics, composites, and similar materials with controllable properties, which is not limited in the present application.

[0038] As an example, metal powder refers to a group of metal particles with a size less than 1 mm, including single metal powder, alloy powder and certain refractory compound powders with metallic properties, which are the main raw materials for powder metallurgy.

[0039] As an example, alloy powder is a metal powder formed by partial or complete alloying of two or more components. Common alloy powders include iron alloy powder, copper alloy powder, nickel alloy powder, cobalt alloy powder, aluminum alloy powder, titanium alloy powder and precious metal alloy powder.

[0040] As an example, ceramic powder refers to a powdered substance obtained by fully mixing and sintering all raw materials when preparing ceramics. The main components of ceramic powder include but are not limited to silicon oxide, aluminum oxide, zirconium oxide, silicon carbide, and silicon nitride.

[0041] As an example, synthetic powder refers to a fine granular substance composed of synthetic resin and various additives, including but not limited to plastic powder composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, colorants, etc. Plastic powder is a synthetic polymer compound.

[0042] As an example, fine powder refers to powder composed of particles with a particle size of 10~44~μm, ultrafine powder refers to powder with a particle size less than 10μm, and ultrafine powder can be further classified according to particle size. Specifically, ultrafine powder can be divided into micron-level (1-10μm), submicron-level (0.1-1μm) and nano-level (1-100nm) powders.

[0043] The fine conveying and uniform feeding of powder materials have always been a difficult problem in the industry, especially for certain metal powders. When the size is small enough to approach the nanoscale, the surface energy increases sharply and agglomeration occurs easily. General feeders, such as traditional worm feeders or gas conveying feeders, are difficult to convey or feed powders with poor fluidity. Blockage, agglomeration, heating and other phenomena often occur during the conveying process.

[0044] In view of this, an embodiment of the present application provides a feeder and a discharge control method thereof. By controlling the different rotation speeds of the first blade group and the second blade group, not only can the occurrence of material blockage and agglomeration be reduced, but the discharge amount can also be accurately controlled, thereby greatly improving material processing efficiency and increasing production capacity.

[0045] Among them, Figure 1 As shown, the feeder includes a feed barrel 1 and a stirring portion 2; the feed barrel 1 defines a receiving chamber 10, and the stirring portion 2 is disposed in the receiving chamber 10. It can be understood that the stirring portion 2 plays a role of stirring the material in the receiving chamber 10.

[0046] Furthermore, along the vertical direction, the upper and lower ends of the feeding barrel 1 respectively have a first feed port 101 and a first discharge port 102, and both the first feed port 101 and the first discharge port 102 are connected to the accommodating chamber 10. It can be understood that the first feed port 101 plays a role in allowing materials to enter, so that the materials enter the accommodating chamber 10 from the upper end of the feeding barrel 1, and the first discharge port 102 can play a role in allowing materials to flow out, so that the materials flow out of the accommodating chamber 10 from the lower end of the feeding barrel 1.

[0047] The stirring part 2 may include a plurality of blade groups 20 , and along the vertical direction, the distance between the plurality of blade groups 20 and the first feed port 101 is greater than the distance between the plurality of blade groups 20 and the first discharge port 102 , and the plurality of blade groups 20 are arranged at intervals in the vertical direction.

[0048] It can be understood that the plurality of blade groups 20 are arranged at intervals in the accommodating chamber 10 along the vertical direction, and respectively play the role of stirring the materials, so that the materials at different positions in the accommodating chamber 10 can be stirred.

[0049] At the same time, the distance between the multiple blade groups 20 and the first feed port 101 is greater than the distance between the multiple blade groups 20 and the first discharge port 102, that is, the multiple blade groups 20 are closer to the first discharge port 102 than the first feed port 101, and can more effectively stir the material near the bottom of the accommodating chamber 10, which helps to ensure the uniform distribution of the material in the feeding barrel 1 and avoid the accumulation or deposition of the material near the bottom of the accommodating chamber 10. When the material needs to be discharged from the first discharge port 102, the blade group 20 close to the first discharge port 102 can help the material flow out more smoothly, thereby reducing the occurrence of material agglomeration and blockage.

[0050] Optionally, in some embodiments of the present application, at least some of the plurality of blade assemblies 20 have different rotation speeds.

[0051] It is understandable that among the multiple blade groups 20, at least some of the blade groups 20 have different rotation speeds, and different rotation speeds can produce different fluid mechanics effects, thereby forming a more complex flow pattern in the accommodating chamber 10. This complex flow pattern helps to better disperse the material.

[0052] At the same time, different blade groups 20 stir the material at different rotation speeds, so that the material is stirred at different rotation speeds at different positions, which can help adjust the flow direction of the material, ensure that the material can be discharged smoothly from the discharge port, and reduce the chance of material blockage or retention.

[0053] It should be noted that in some other embodiments of the present application, the rotation speed of at least part of the blade groups 20 can be the same, that is, at least part of the blade groups 20 stir the material at the same rotation speed, so that the material is subjected to the same stirring effect, thereby ensuring the uniformity of material dispersion.

[0054] In other embodiments, the rotation speed of any blade set 20 in the plurality of blade sets 20 is not the same as that of other blade sets 20. In other words, the plurality of blade sets 20 stir the material according to their respective rotation speeds, further increasing the complexity of the flow pattern inside the accommodating chamber 10, further increasing the dispersion effect of the material, and reducing the probability of material clogging and agglomeration.

[0055] Specifically, in some embodiments of the present application, Figure 2 As shown, the plurality of blade groups 20 include adjacent first blade groups 201 and second blade groups 202 . The first blade group 201 is closer to the first feed port 101 than the second blade group 202 . The rotation speed of the first blade group 201 is greater than that of the second blade group 202 .

[0056] That is to say, among the multiple blade groups 20, the blade group 20 near the first feed port 101 has a higher rotation speed, which can quickly disperse the material entering the first feed port 101 into the entire accommodating chamber 10, helping to avoid accumulation of materials near the feed port, improving the dispersion efficiency of the material, and helping to evenly distribute the material in the feeding barrel 1.

[0057] At the same time, a faster rotation speed means that the first blade group 201 can generate a stronger stirring force, thereby dispersing the material more effectively.

[0058] It can be understood that when the material passes through the first blade group 201 and reaches the second blade group 202, it has already undergone preliminary dispersion. At this time, the second blade group 202 stirs at a slower rotation speed, which can further disperse the material evenly, improve the uniformity of material dispersion, and prevent the material from being unevenly dispersed due to excessively fast stirring.

[0059] At the same time, the second blade assembly 202 helps the material to flow out from the first discharge port 102. The slower rotation speed can ensure that the material is discharged evenly, reducing the probability of blockage and agglomeration.

[0060] Optionally, in some embodiments of the present application, in combination Figure 1 and Figure 2 As shown, the feeder includes a feeding barrel 1 defining a accommodating chamber 10, and a stirring portion 2 arranged in the accommodating chamber 10, wherein, along the vertical direction, the upper end and the lower end of the feeding barrel 1 respectively have a first feed port 101 and a first discharge port 102, the first feed port 101 and the first discharge port 102 are both connected to the accommodating chamber 10, the stirring portion 2 includes a first blade group 201 and a second blade group 202 arranged adjacent to each other, the first blade group 201 and the second blade group 202 are arranged at intervals in the vertical direction, and the first blade group 201 is closer to the first feed port 101 than the second blade group 202, the distance between the first blade group 201 and the first feed port 101 is greater than the distance between the first blade group 201 and the first discharge port 102, and the rotation speed of the first blade group 201 is greater than the rotation speed of the second blade group 202.

[0061] And, if Figure 3 As shown, the discharge control method of the feeder includes: S1, in response to the discharging instruction, determining the discharging amount per unit time.

[0062] The discharge instruction can be set and triggered by the user. The discharge amount per unit time can be the discharge amount per hour, the discharge amount per minute, the discharge amount per second, etc., and this application does not make specific restrictions on this.

[0063] S2, controlling the first blade group and the second blade group to perform stirring at different rotation speeds according to the discharge amount per unit time.

[0064] The discharge amount per unit time can be identified as the discharge speed. Each discharge speed corresponds to a set of blade group rotation speeds, namely, the rotation speed of the first blade group and the rotation speed of the second blade group. Different discharge speeds correspond to at least one of the rotation speeds of the first blade group and the second blade group.

[0065] Based on the up and down settings of the first blade group and the second blade group and the different rotation speeds, and controlling the first blade group and the second blade group to stir at different rotation speeds through the discharge amount per unit time, not only can the occurrence of material blockage and agglomeration be reduced, but also the discharge amount can be accurately controlled, thereby greatly improving the material processing efficiency.

[0066] Optionally, in some embodiments of the present application, the blades in the first blade group can be extended and retracted in the horizontal direction, that is, the length of the blades in the first blade group can be adjusted. Figure 4 As shown, before controlling the first blade group and the second blade group to perform stirring at different rotation speeds according to the discharge amount per unit time, the discharge control method further includes: S11, determining the target length of the blade according to the discharge volume per unit time.

[0067] That is, different discharge speeds may correspond to different target blade lengths, which may be configured in advance, and this application does not impose any specific restrictions on this.

[0068] S12, controlling the blades in the first blade group to extend and retract in the horizontal direction according to the target length of the blades, so as to adapt the discharge speed.

[0069] Therefore, the embodiment of the present application arranges the blades in the first blade group to be retractable in the horizontal direction, so as to control the horizontal length of the blades in the first blade group to match the discharge amount per unit time, thereby achieving precise matching of stirring efficiency and discharge. This can not only improve the discharge efficiency, but also further avoid the occurrence of material blockage and agglomeration.

[0070] Optionally, in some specific embodiments of the present application, Figure 5 As shown, the above step S2 may include: S21, determining a target rotation speed of the first blade group according to the discharge amount per unit time, and determining a target rotation speed of the second blade group according to the target rotation speed of the first blade group and a rotation speed relationship between the first blade group and the second blade group.

[0071] The rotational speed relationship between the first blade group and the second blade group may be preconfigured. For example, the rotational speed relationship between the first blade group and the second blade group may satisfy the following relationship: 0.5n1≤n2≤0.9n1, Wherein, n1 is the rotation speed of the first blade group, and n2 is the rotation speed of the second blade group.

[0072] S22, controlling the first blade group to perform a stirring operation according to a target rotation speed of the first blade group, and controlling the second blade group to perform a stirring operation according to a target rotation speed of the second blade group.

[0073] It can be understood that since the rotational speed ratio of the first blade group 201 and the second blade group 202 satisfies the above-mentioned relationship, on the one hand, a complex flow pattern can be formed in the accommodating chamber 10 to ensure the uniform distribution of the material in the accommodating chamber 10, and the probability of material agglomeration and clogging can be reduced; on the other hand, it can ensure that the rotational speed difference between the first blade group 201 and the second blade group 202 is not too large, which helps to balance the fluid dynamics effect in the accommodating chamber 10, allowing the material to maintain uniform flow and reduce the probability of uneven distribution or uneven stirring of the material.

[0074] Optionally, in some embodiments of the present application, the number of blades in the first blade group 201 is less than the number of blades in the second blade group 202 .

[0075] Among them, the first blade group is close to the first feed port and has fewer blades, which can make the material subject to less shear force and impact force when it just enters the containing chamber. At the same time, the smaller number of blades also helps the material to pass through the first feed port more quickly and disperse into the entire containing chamber; the second blade group has more blades and can provide stronger stirring force and shear force. This design helps to disperse the material more fully and improve the stirring efficiency and material uniformity.

[0076] In addition, the present application also provides a feeder, combined with Figure 1 , Figure 2 and Figure 6 As shown, the feeder includes: a feed bucket 1, a stirring part 2 and a control part 5.

[0077] The feeding barrel 1 defines a accommodating chamber 10, and along the vertical direction, the upper end and the lower end of the feeding barrel 1 respectively have a first feed port 101 and a first discharge port 102, and the first feed port 101 and the first discharge port 102 are both connected to the accommodating chamber 10; the stirring part 2 is arranged in the accommodating chamber 10, and the stirring part 2 includes a first blade group 201 and a second blade group 202 that are adjacently arranged, and the first blade group 201 and the second blade group 202 are arranged at intervals in the vertical direction, and the first blade group 201 is closer to the first feed port 101 than the second blade group 202, the distance between the first blade group 201 and the first feed port 101 is greater than the distance between the first blade group 201 and the first discharge port 102, and the rotation speed of the first blade group 201 is greater than the rotation speed of the second blade group 202; the control part 5 is constructed to determine the discharge amount per unit time in response to the discharge instruction, and control the first blade group 201 and the second blade group 202 to stir at different rotation speeds according to the discharge amount per unit time.

[0078] Since the first blade group and the second blade group are arranged up and down and have different rotation speeds, the control unit controls the first blade group and the second blade group to stir at different rotation speeds based on the discharge amount per unit time. This can not only reduce the occurrence of material blockage and agglomeration, but also accurately control the discharge amount, greatly improving the material processing efficiency.

[0079] In some other embodiments, the feeder further includes a driving mechanism 3 , which is connected to the plurality of blade groups 20 to drive the blade groups 20 to rotate.

[0080] It is understandable that multiple blade groups 20 are connected to the same driving mechanism 3, and the driving mechanism 3 can simultaneously drive multiple blade groups 20 to rotate. At this time, multiple blade groups 20 share a common power source, which improves the driving efficiency and reduces the possibility of uneven material stirring caused by driving failure.

[0081] As an example, the driving component includes, but is not limited to, a power source including a motor, a cylinder, and an oil cylinder, and this solution does not limit this.

[0082] In some other embodiments, the feeder further includes a transmission mechanism 4, and the driving mechanism 3 is connected to the plurality of blade groups 20 via the transmission mechanism 4, so that the rotation speeds of the plurality of blade groups 20 are different.

[0083] It can be understood that the transmission mechanism 4 is located between the blade group 20 and the driving mechanism 3, and makes the rotation speeds of multiple blade groups 20 different. That is to say, the transmission mechanism 4 can play a differential role, which is convenient for adapting to different stirring requirements of the material, realizing precise stirring of the material, and helping to reduce the probability of material agglomeration and clogging.

[0084] As an example, the transmission mechanism 4 includes various transmission mechanisms 4 including but not limited to a gear transmission mechanism, a multi-link transmission mechanism, a worm gear transmission mechanism, a cam transmission mechanism, and a belt transmission mechanism.

[0085] As an example, the gear transmission mechanism 4 refers to a component composed of at least two gears that rotate along different axes to achieve transmission, wherein different gears have different diameters.

[0086] In some other embodiments, the feeder further includes a driving mechanism 3 , which is provided in plurality, and each driving mechanism 3 is connected to a corresponding blade assembly 20 .

[0087] It can be understood that multiple driving mechanisms 3 drive corresponding blade groups 20 respectively, that is, the driving mechanisms 3 of each blade group 20 are independent of each other, and the rotation speed, direction and working time of each blade group 20 can be independently adjusted to achieve more precise stirring.

[0088] Optionally, in some embodiments of the present application, the blades in the first blade group 201 are retractable in the horizontal direction, wherein the control unit 5 is also configured to determine the target length of the blades according to the discharge amount per unit time before controlling the first blade group 201 and the second blade group 202 to perform stirring at different rotation speeds according to the discharge amount per unit time, and control the blades in the first blade group to retract in the horizontal direction according to the target length of the blades, so as to adapt to the discharge speed.

[0089] Since the blades in the first blade group are retractable in the horizontal direction, the control unit 5 can control the horizontal length of the blades in the first blade group to match the discharge volume per unit time, thereby achieving precise matching of stirring efficiency and discharge, which can not only improve the discharge efficiency, but also further avoid the occurrence of material blockage and agglomeration.

[0090] Optionally, in some embodiments of the present application, Figure 6 As shown, the control unit 5 includes: a speed determination unit 51 and a drive control unit 52. The speed determination unit 51 is used to determine the target speed of the first blade group 201 according to the discharge amount per unit time, and to determine the target speed of the second blade group 202 according to the target speed of the first blade group 201 and the speed relationship between the first blade group 201 and the second blade group 202. The drive control unit 52 is used to control the first blade group 201 to perform stirring according to the target speed of the first blade group 201, and to control the second blade group 202 to perform stirring according to the target speed of the second blade group 202.

[0091] It should be noted that the driving control unit 52 is used to drive and control the first blade group 201 and the second blade group 202 , and may include the driving mechanism 3 and the transmission mechanism 4 mentioned above.

[0092] The rotational speed relationship between the first blade group 201 and the second blade group 202 may be preconfigured. For example, the rotational speed relationship between the first blade group 201 and the second blade group 202 may satisfy the following relationship: 0.5n1≤n2≤0.9n1, Wherein, n1 is the rotation speed of the first blade group 201 , and n2 is the rotation speed of the second blade group 202 .

[0093] It can be understood that since the rotational speed ratio of the first blade group 201 and the second blade group 202 satisfies the above-mentioned relationship, on the one hand, a complex flow pattern can be formed in the accommodating chamber 10 to ensure the uniform distribution of the material in the accommodating chamber 10, and the probability of material agglomeration and clogging can be reduced; on the other hand, it can ensure that the rotational speed difference between the first blade group 201 and the second blade group 202 is not too large, which helps to balance the fluid dynamics effect in the accommodating chamber 10, allowing the material to maintain uniform flow and reduce the probability of uneven distribution or uneven stirring of the material.

[0094] In other embodiments, Figure 7 As shown, the blade group 20 includes a main body 21 and a plurality of blades 22. The plurality of blades 22 are arranged on the outer periphery of the main body 21, and the plurality of blades 22 are arranged at intervals along the circumference of the main body 21. That is, the plurality of blades 22 are arranged at intervals around the main body 21. When the main body 21 rotates, the blades rotate with the main body 21 to play a role in stirring the material.

[0095] An elastic part 23 is provided between the blade 22 and the main body 21, and the elastic part 23 is configured to provide a downward pressing force for the blade 22. It is understandable that the elastic part 23 presses the blade 22 downward, and the elastic part 23 provides a downward pressing force for the blade, which can press the material under the blade 22, thereby facilitating the discharge of the material and improving the material discharge efficiency.

[0096] In addition, the elastic portion 23 has elastic expansion and contraction properties, which reduces the probability of the blades 22 being damaged when stirring the materials, and reduces the probability of the blades 22 being damaged by large-sized materials.

[0097] In other embodiments, at least some of the blade assemblies 20 have different numbers of blades 22 .

[0098] That is, at least some of the blade groups 20 have different numbers of blades 22, and the other parts of the blade groups 20 have the same number of blades 22. The blade groups 20 with different numbers of blades have different stirring forces on the material, which helps to optimize the flow characteristics of the blade groups 20, reduce fluid resistance, and improve the flow efficiency and uniformity of the material.

[0099] At the same time, blade groups 20 with different numbers of blades can form different stirring modes and shear forces. Such differential stirring effects help to better disperse the material and reduce the probability of the material accumulating in a certain place.

[0100] In addition, the blade groups 20 with the same number of blades can stir the material with the same intensity, thereby ensuring the uniformity of the material and reducing the probability of uneven distribution of the material.

[0101] In other embodiments, the plurality of blade groups 20 include adjacent first blade groups 201 and second blade groups 202, and the first blade group 201 is closer to the first feed port 101 than the second blade group 202. In other words, the first blade group 201 and the second blade group 202 are at different distances from the first feed port 101, and the first feed port 101 and the second feed port are stirred at different positions from the first feed port 101, respectively.

[0102] The number of blades in the first blade group 201 is less than the number of blades in the second blade group 202. That is, the number of blades in the blade group 20 close to the first feed port 101 is small, so that the material is subjected to less shear force and impact force when it first enters the receiving chamber 10, which helps the material to quickly pass through the first blade group 201 and be dispersed into the entire receiving chamber 10 as soon as possible, thereby ensuring the entry efficiency and dispersion efficiency of the material.

[0103] It can be understood that the second blade group 202 is located farther away from the first feed port 101 than the first blade group 201, and has a larger number of blades, which can provide stronger stirring force and shear force, help to fully disperse the material, ensure the dispersion effect and uniformity of the material, and reduce the chance of material agglomeration and blockage.

[0104] In a specific embodiment of the present application, the feeder includes a feed barrel 1, which has a receiving chamber 10. In the vertical direction, the upper and lower ends of the feed barrel 1 respectively have a first feed port 101 and a first discharge port 102, and the first feed port 101 and the first discharge port 102 are both connected to the receiving chamber 10. The first feed port 101 and the first discharge port 102 respectively play the role of inflow and outflow of materials.

[0105] A stirring portion 2 is provided in the accommodating chamber 10, and the stirring portion 2 includes a plurality of blade groups 20, such as a first blade group 201 and a second blade group 202. Along the vertical direction, the distance between the plurality of blade groups 20 and the first feed port 101 is greater than the distance between the plurality of blade groups 20 and the first discharge port 102, and the plurality of blade groups 20 are spaced apart in the vertical direction.

[0106] A plurality of blade groups 20 are arranged at intervals in the accommodating chamber 10 near the first discharge port 102, and play the role of stirring the material, so that the material is fully stirred in the accommodating chamber 10, and the influence of stirring on the material inflow efficiency is reduced, thereby ensuring the overall working efficiency of the feeder and reducing the probability of material clumping and clogging of the feeder.

[0107] The blade assembly 20 includes a main body 21 and a plurality of blades 22 . The plurality of blades 22 are arranged on the outer periphery of the main body 21 and are spaced apart along the circumference of the main body 21 . An elastic portion 23 is arranged between the blades 22 and the main body 21 . The elastic portion 23 is configured to provide a downward pressing force for the blades 22 .

[0108] The blade 22 is fixed to the outer periphery of the main body 21 through the elastic part 23. The elastic part 23 presses the blade 22 against the powder, thereby applying pressure to the material to promote the outflow of the material. When encountering large particles, the blade 22 presses the elastic part 23 to retract, thereby reducing the damage of the large particles to the blade 22.

[0109] As an example, the elastic part 23 includes elastic parts including but not limited to springs, washers, and rubber bearings.

[0110] As an example, a spring is a device composed of a resilient but mostly rigid material that is bent or molded into a shape that returns to shape after being compressed or stretched.

[0111] As an example, a gasket refers to an elastic gasket that separates the connection surfaces, including but not limited to flat washers, spring washers, locking washers, rubber washers, etc.

[0112] As an example, a rubber bearing refers to an elastic member composed of a metal panel and a rubber core. The main structure includes two upper and lower metal panels and a rubber core. The shapes of the holes in the rubber core are also different, such as round, square, rectangular, etc.

[0113] Furthermore, at least some of the multiple blade groups 20 have different rotation speeds, and at least some of the multiple blade groups 20 have different numbers of blades. For example, the first blade group 201 is closer to the first feed port 101 than the second blade group 202, the rotation speed of the first blade group 201 is greater than the rotation speed of the second blade group 202, and the number of blades in the first blade group 201 is less than the number of blades in the second blade group 202.

[0114] Since the rotational speed ratio between the first blade group 201 and the second blade group 202 satisfies the above relationship, on the one hand, a complex flow pattern can be formed in the accommodating chamber 10 to ensure uniform distribution of the material in the accommodating chamber 10, thereby reducing the probability of material agglomeration and clogging; on the other hand, it can ensure that the rotational speed difference between the first blade group 201 and the second blade group 202 is not too large, which helps to balance the fluid dynamics effect in the accommodating chamber 10, allowing the material to maintain uniform flow and reducing the probability of uneven distribution or uneven stirring of the material.

[0115] It can be understood that the first blade group 201 near the first feed port 101 has a small number of blades and a fast rotation speed, which is conducive to the rapid inflow and dispersion of materials. The second blade group 202 near the first discharge port 102 has a large number of blades and a slow rotation speed, which is conducive to the uniform dispersion of materials and reduces the probability of material agglomeration and blockage.

[0116] Specifically, the number of blades 22 in the blade group 20 may be 1 to 6, preferably 3 to 4.

[0117] The feeder further comprises a driving mechanism 3 and a transmission mechanism 4, wherein the transmission mechanism 4 is located between the driving mechanism 3 and the blade set 20. There are multiple driving mechanisms 3, and each driving mechanism 3 is connected to a corresponding blade set 20.

[0118] It can be understood that each blade group 20 has its own independent driving mechanism 3, which enables precise control of the blade group 20, further improves the material dispersion effect, can meet different stirring requirements, and further reduces the probability of material agglomeration and clogging.

[0119] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0120] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
