Description

Technical Field

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

[0002] A feeder is a device used for material conveying, 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] During the use of the feeder, material agglomeration and clogging is a problem that cannot be ignored. Therefore, how to avoid material clogging and agglomeration is a technical problem that needs to be solved today. Summary of the invention

[0004] The present application provides a feeder, which reduces the occurrence of material clogging and agglomeration.

[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 feeding machine, comprising a feeding barrel and a stirring part; the feeding barrel has a accommodating chamber, and 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, and the first feed port and the first discharge port are both connected to the accommodating chamber; the stirring part is arranged in the accommodating chamber, wherein the stirring part comprises a plurality of blade groups, and along the vertical direction, the distance between the plurality of blade groups and the first feed port is greater than the distance between the plurality of blade groups and the first discharge port, and the plurality of blade groups are arranged at intervals in the vertical direction; the blade group comprises a main body and a plurality of blades, the plurality of blades are arranged on the outer periphery of the main body and are arranged at intervals along the circumference of the main body, an elastic part is arranged between the blades and the main body, and the elastic part is configured to provide a downward pressing force for the blades.

[0006] The feeder proposed in the embodiment of the present application, the first feed port can play a role in allowing materials to enter the accommodating chamber, the first discharge port can play a role in allowing materials to leave the accommodating chamber, and the stirring part can play a role in stirring the materials, wherein the multiple blade groups in the stirring part are arranged in the accommodating chamber along the vertical direction, and the materials can be stirred at different positions in the accommodating chamber, and the distance between the multiple blade groups and the first feed port is greater than the distance between the multiple blade groups and the first discharge port, so that the materials near the bottom of the accommodating chamber can be stirred more effectively, which helps to ensure the uniform distribution of the materials in the feeding barrel and avoid the materials from being deposited at the bottom of the accommodating chamber or forming dead corners. When the materials need to be discharged from the first discharge port, the blade group close to the discharge port can help the materials to flow out more smoothly, thereby reducing the occurrence of material agglomeration and blockage. The elastic part is arranged between the blade and the main body, so that the blade has elastic displacement relative to the main body, and can stir the materials and apply pressure to the materials. After encountering larger-sized materials, the elastic part is pressed to retract, thereby reducing the damage of the blades to the large-sized materials.

[0007] Optionally, there is one elastic part, the blade assembly further includes a connecting ring, the connecting ring is arranged on the outer periphery of the main body, the elastic part is arranged between the connecting ring and the main body, and the plurality of blades are fixedly connected to the connecting ring.

[0008] In the above scheme, multiple blades are arranged on a connecting ring, which can ensure the relative position between the blades is stable and avoid relative displacement or deformation of the blades during rotation or force. At the same time, the elastic part can absorb and buffer external impact force, thereby automatically optimizing the stress state of the blade group according to the stress conditions, thereby reducing the chance of large-size materials damaging the blades.

[0009] Optionally, the stirring portion further comprises a stirring rod, the stirring rod extends in a vertical direction, and the main body portion and the connecting ring are both sleeved on the stirring rod.

[0010] In the above scheme, the stirring rod extends in the vertical direction, which can ensure that the blade group can fully cover the bottom and surrounding areas of the stirring container during the stirring process, which helps to achieve a more uniform stirring effect. The main body and the connecting ring are both mounted on the stirring rod to form a stable support structure, which makes it difficult for the blade group to shake or tilt during stirring, which helps to ensure stirring uniformity.

[0011] Optionally, the feeder further comprises a coil spring, which is sleeved on the stirring rod. The stirring rod has a limiting step surface. Along the axial direction of the stirring rod, two ends of the coil spring are respectively fixedly connected to the limiting step surface and the connecting ring.

[0012] In the above scheme, the coil spring can play a role of elastic expansion and contraction, which can further increase the downward pressure on the blades, and help the blade group to remain stable during the mixing process, thereby ensuring the uniformity and consistency of the mixing effect.

[0013] Optionally, a limit block is provided on the stirring rod, and the limit block is provided below the plurality of blades to limit the extent to which the blades are bent downward.

[0014] In the above scheme, the limit block can limit the downward bending extent of the blade. Since the downward pressure of the blade is increased, the limit block can further ensure that the blade maintains a relatively stable shape and angle during the mixing process, ensure the uniformity of material stirring, and prevent the blade from being damaged due to excessive deformation.

[0015] Optionally, the multiple blade groups include a first blade group and a second blade group that are adjacent to each other, the first blade group is closer to the first feed port than the second blade group, and a rotation speed of the first blade group is greater than a rotation speed of the second blade group.

[0016] In the above scheme, 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 containing chamber, which helps to avoid material accumulation near the feed port and ensures that the material is evenly distributed 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 toward the second blade group, it has undergone a certain degree of dispersion. At this time, the second blade group continues to stir at a slower rotation speed, which can further refine the dispersion effect and prevent excessive stirring from affecting the efficiency of material discharge.

[0017] Optionally, the rotational speed of the first blade group is t1, and the rotational speed of the second blade group is t2, satisfying: 0.5t1≤t2≤0.9t1.

[0018] In the above scheme, since the rotation speed of the first blade group and the rotation speed of the second blade group satisfy the above relationship, 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 difference between the rotation speed of the first blade group and the rotation speed of the second blade group is not too large, which helps to balance the fluid dynamics effect in the containing chamber, avoid affecting the uniform flow of the material, and reduce the probability of uneven material distribution or uneven stirring.

[0019] Optionally, the feeder further comprises a driving mechanism, which is connected to the plurality of blade groups to drive the blade groups to rotate.

[0020] In the above scheme, multiple blade groups are connected to the same driving mechanism, and the driving mechanism drives the multiple blade groups to rotate simultaneously, thereby improving the driving efficiency and reducing the possibility of uneven material stirring caused by driving failure.

[0021] Optionally, the feeder further comprises a driving mechanism, wherein there are multiple driving mechanisms, and each driving mechanism is connected to a corresponding blade group.

[0022] In the above scheme, the driving mechanisms can respectively drive their corresponding blade groups, that is, each blade group is controlled by an independent driving mechanism, and the rotation speed, direction and working time of each blade group can be independently adjusted to achieve more precise stirring.

[0023] Optionally, at least some of the blade groups have different numbers of blades.

[0024] In the above scheme, the number of blades in some blade groups is different, so that different blade groups have different stirring strengths on the material, which helps to optimize the flow characteristics of the blade groups, reduce fluid resistance, and improve the flow efficiency and uniformity of the material. In addition, blade groups with different numbers of blades can form different stirring patterns and shear forces. This differential stirring effect helps to better disperse the material.

[0025] Optionally, the multiple blade groups include a first blade group and a second blade group that are adjacent to each other, the first blade group is closer to the first feed port than the second blade group, and the number of blades in the first blade group is less than the number of blades in the second blade group.

[0026] 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. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The term "multiple" as used in the present application refers to more than two (including two). Similarly, the term "multiple groups" refers to more than two groups (including two groups), and the term "multiple sheets" refers to more than two sheets (including two sheets).

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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. 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.

[0042] 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.

[0043] As an example, fine powder refers to powder composed of particles with a particle size of 10μm-44μm, and ultrafine powder refers to powder with a particle size less than 10μm. Ultrafine powder can be further classified according to particle size. Specifically, ultrafine powder can be divided into micron-level (1μm-10μm), submicron-level (0.1μm-1μm) and nano-level (1nm-100nm) powders.

[0044] 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.

[0045] In view of this, in order to reduce the occurrence of material agglomeration and clogging, the embodiment of the present application provides a feeder, such as Figure 1 As shown, it includes a feeding barrel 1 and a stirring part 2; the feeding barrel 1 has a containing chamber 10, and the stirring part 2 is arranged in the containing chamber 10. It can be understood that the stirring part 2 plays a role of stirring the material in the containing chamber 10.

[0046] 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 material entry, so that the material enters the accommodating chamber 10 from the upper end of the feeding barrel 1, and the first discharge port 102 can play a role in material outflow, so that the material flows out of the accommodating chamber 10 from the lower end of the feeding barrel 1.

[0047] The stirring part 2 includes a plurality of blade groups 20 . In 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 . 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] like Figure 3 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.

[0051] 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.

[0052] In addition, since the elastic portion 23 has the ability to elastically expand and contract, the probability of the blades 22 being damaged can be reduced when stirring the materials, and the probability of the blades 22 being damaged by large-sized materials can be reduced.

[0053] In other embodiments, please refer to Figure 2 , there is one elastic part 23, and it can be understood that the elastic part 23 can absorb and buffer the external impact force.

[0054] The blade assembly 20 also includes a connecting ring 24, which is arranged on the outer periphery of the main body 21, and the elastic part 23 is arranged between the connecting ring 24 and the main body 21. It can be understood that the elastic part 23 can absorb and buffer the impact force between the connecting ring 24 and the main body 21, thereby automatically optimizing the stress state of the blade assembly 20 according to the stress conditions, thereby reducing the probability of large-sized materials damaging the blades 22.

[0055] The plurality of blades 22 are all fixedly connected to the connecting ring 24 , which can ensure that the relative positions of the blades 22 are stable and prevent the blades 22 from being relatively displaced or deformed during rotation or force application.

[0056] That is to say, each blade 22 is no longer provided with a separate elastic part 23 to connect with the main body 21, but multiple blades 22 are connected to one elastic part 23 through a connecting ring 24, and the elastic part 23 is connected to the main body, so only one elastic part 23 is required, thereby simplifying the structure of the blade group 20 and improving the production efficiency and installation efficiency of the blade group 20.

[0057] In other embodiments, please refer to Figure 3 The stirring part 2 also includes a stirring rod 5, which extends in a vertical direction, and can ensure that the blade assembly 20 can fully cover the bottom and surroundings of the stirring container during the stirring process, which helps to achieve a more uniform stirring effect.

[0058] In addition, the stirring rod 5, as a core component of the stirring part 2, extends in the vertical direction, which helps to ensure the stability of the entire stirring part 2 during the stirring process.

[0059] The main body 21 and the connecting ring 24 are both sleeved on the stirring rod 5 to form a stable supporting structure, so that the blade assembly 20 is not easy to shake or tilt during stirring, which helps to ensure stirring uniformity.

[0060] In other embodiments, please refer to Figure 3 The feeder also includes a coil spring 230. It can be understood that the coil spring 230 can play an elastic expansion role, which helps to absorb and disperse the energy when the blade 22 encounters material resistance and further increase the downward pressure on the blade.

[0061] The coil spring 230 is sleeved on the stirring rod 5 . The stirring rod 5 has a limiting step surface 51 . Along the axial direction of the stirring rod 5 , two ends of the coil spring 230 are fixedly connected to the limiting step surface 51 and the connecting ring 24 , respectively.

[0062] It is understandable that when encountering material resistance, the coil spring 230 can adjust the position and stirring force of the blade 22 through its elastic deformation, so that the blade assembly 20 remains stable during the stirring process, thereby ensuring the uniformity of the stirring effect.

[0063] The coil spring 230 and the elastic member 23 can jointly apply a downward force to the connecting ring 24, so as to squeeze the material under the blade 22, thereby facilitating the discharge of the material and improving the material discharge efficiency.

[0064] In other embodiments, please refer to Figure 3 A limiting block 6 is provided on the stirring rod 5, and the limiting block 6 is provided below the plurality of blades 22 to limit the bending range of the blades 22 downward.

[0065] It is understandable that during the stirring process, the blades 22 may bend and deform to a certain extent due to factors such as material resistance and rotation speed. The bending and deformation of the blades 22 may affect the stirring effect and cause uneven distribution of the material. The limit block 6 limits the bending range of the blades 22 toward the bottom, thereby ensuring that the blades 22 maintain a relatively stable shape and angle during the stirring process, ensuring the uniformity of material stirring, and preventing the blades 22 from being damaged due to excessive deformation.

[0066] Since the downward pressure of the blade 22 is increased, in order to ensure that the blade 22 does not bend downward too much, a limit block 6 is provided, and the limit block 6 can limit the deformation range of the blade 22.

[0067] In addition, the limit block 6 not only limits the bending range of the blade 22, but also provides additional support for the entire stirring part 2. During the stirring process, the limit block 6 can reduce the shaking or tilting of the blade 22 due to uneven force, thereby enhancing the structural stability of the entire stirring part 2.

[0068] It can be understood that the outer periphery of the stirring rod 5 is provided with an annular groove surrounding the axis of the stirring rod 5, the main body 21 is arranged in the annular groove, the upper side wall of the annular groove is a limiting step surface 51, and the lower end of the main body 21 stops at the lower side wall of the annular groove.

[0069] In other embodiments, at least some of the plurality of blade assemblies 20 rotate at different speeds.

[0070] 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.

[0071] 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.

[0072] Among them, at least part of the blade groups 20 have the same rotation speed, 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 dispersion of the material.

[0073] 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.

[0074] In other embodiments, 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 .

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] In other embodiments, the rotation speed of the first blade group is t1, and the rotation speed of the second blade group is t2, satisfying: 0.5t1≤t2≤0.9t1.

[0080] It can be understood that since the rotational speeds of the first blade group 201 and the second blade group 202 satisfy the above ratio, 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, thereby reducing the probability of material agglomeration and blockage; on the other hand, it can ensure that the difference between the rotational speed of the first blade group 201 and the rotational speed of 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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 .

[0089] 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.

[0090] In other embodiments, at least some of the blade assemblies 20 have different numbers of blades 22 .

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] In other specific embodiments, the feeder includes a feed barrel 1, the feed barrel 1 has a containing chamber 10, and along the vertical direction, the upper end and the lower end 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 containing chamber 10. The first feed port 101 and the first discharge port 102 respectively play the role of inflow and outflow of materials.

[0098] A stirring portion 2 is provided in the accommodating chamber 10, and the stirring portion 2 includes a plurality of blade groups 20. 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.

[0099] 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.

[0100] 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 .

[0101] The blade 22 is fixed to the outer periphery of the main body 21 through the elastic part 23, and the spiral spring 230 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 and the spiral spring 230 to retract, thereby reducing the damage of the large particles to the blade 22.

[0102] As an example, the elastic part 23 includes but is not limited to elastic members including washers and rubber bearings.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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, wherein the multiple 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 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.

[0107] The rotation speed of the first blade group is t1, and the rotation speed of the second blade group is t2, which satisfies: 0.5t1≤t2≤0.9t1.

[0108] Since the rotational speeds of the first blade group 201 and the second blade group 202 satisfy the above ratio, 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 blockage; on the other hand, it can ensure that the difference between the rotational speed of the first blade group 201 and the rotational speed of 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.

[0109] 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.

[0110] Specifically, the number of blades 22 in the blade group 20 may be 1 to 6, preferably 3 to 4.

[0111] 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 assembly 20. There are multiple driving mechanisms 3 and multiple transmission mechanisms 4, and each driving mechanism 3 is connected to a corresponding blade assembly 20 through a corresponding transmission mechanism 4.

[0112] 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.

[0113] 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.

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.
