However, in the related art, the blades of the stirring part are too large, and it is easy to collide with the barrel during installation, causing the barrel and the blades to be easily damaged. Utility Model Content

[0003] The present application provides a feeder, which solves the technical problem that the blades of the stirring part are too large and easily collide with the barrel body during installation, causing the barrel body and the blades to be easily damaged.

[0004] In order to achieve the above objectives, the main technical solutions adopted in this application include:

[0005] An embodiment of the present application provides a feeding machine, which includes a feeding barrel and a stirring part. The feeding barrel has a accommodating chamber. 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. Along the vertical direction, the stirring part is closer to the first discharge port than the first feed port, wherein the stirring part includes a stirring rod and a blade group, the blade group includes at least one blade, the blade is arranged on the stirring rod and extends in the radial direction of the stirring rod, and the size of the blade is adjustable along the radial direction of the stirring rod.

[0006] The feeder proposed in the embodiment of the present application has an adjustable blade size along the radial direction of the stirring rod, that is, the blade size can be changed along the radial direction of the stirring rod. When installing the feeder, the blade size (blade length) in the radial direction of the stirring rod can be adjusted to make the blade length shorter, reduce the probability of collision between the stirring part and the feeding bucket, and improve the stability and reliability of the feeder. After the feeder is installed, the blade length can be adjusted to fit the inner wall of the feeding bucket, increasing the range of the stirring part to squeeze and stir the powder.

[0007] Optionally, along the radial direction of the stirring portion, the blade includes a first section and a second section, the first section is fixed to the stirring rod, and the second section is movably disposed on the first section.

[0008] The second section is movably arranged on the first section, so that the stirring effect can be optimized according to the properties and distribution range of the powder, the operating efficiency of the feeder can be improved, the probability of friction or collision between the second section and the feeder can be reduced, and the operating stability of the feeder can be improved.

[0009] Optionally, along the radial direction of the agitating portion, a first channel is provided in the first section, and at least a portion of the second section is provided in the first channel.

[0010] At least part of the second section is arranged in the first channel. On the one hand, it can reduce the overall size of the stirring part of the feeder, make the stirring part more compact as a whole, and reduce the probability of collision or friction between the stirring part and the inner wall of the feeding barrel; on the other hand, the stirring path can be optimized by adjusting the position of the second section in the first section, so that the mixing of the powder and the stirring part is more sufficient and uniform.

[0011] Optionally, a first protrusion is provided in the first channel, and a second protrusion is provided on the second section, and the first protrusion is suitable for cooperating with the second protrusion to limit the second section from being separated from the first channel.

[0012] The first protrusion is suitable for cooperating with the second protrusion to limit the second section from detaching from the first channel. The cooperating design of the first protrusion and the second protrusion can effectively prevent the second section of the blade from accidentally falling off due to excessive force during the stirring process, thereby improving the overall structural stability of the stirring part and ensuring the continuous and stable operation of the feeder.

[0013] Optionally, the stirring portion further includes a first driving member, which is disposed in the first channel and fixedly connected to the first section, and a driving end of the first driving member is connected to the second section.

[0014] The first driving member is arranged in the first channel and fixedly connected to the first section. The driving end of the first driving member is connected to the second section. On the one hand, it can make the stirring part more compact and reduce the overall volume of the stirring part. On the other hand, the first driving member directly drives the second section, reducing the intermediate transmission links and improving the stability and reliability of the drive.

[0015] Optionally, the first driving member is configured as a linear motor, and a driving shaft of the linear motor is fixedly connected to the second section.

[0016] The first driving member is constructed as a linear motor, and the driving shaft of the linear motor is fixedly connected to the second section. The linear motor can achieve high-precision position control and speed control, and can more accurately control the position of the second section, thereby controlling the length of the blade and reducing the probability of collision between the blade and the inner wall of the feeding barrel.

[0017] Optionally, the stirring portion further comprises a first spring, one end of the first spring is connected to the second section, and the other end of the first spring is connected to the first section.

[0018] The setting of the first spring can reduce the energy consumption during the mixing process. When the second section encounters the resistance of the powder, the first spring will absorb part of the energy and store it, and then release this energy when the second section rebounds. This energy recovery mechanism helps to reduce the energy consumption of the equipment and improve the energy efficiency ratio.

[0019] Optionally, a sealing portion is provided on the inner wall of the first channel, the sealing portion is interference fit with the second section, and the sealing portion is constructed as an elastic member.

[0020] The interference fit between the sealing portion and the second section ensures close contact between the two, thereby effectively preventing powder from entering the first channel or the first section during the mixing process, and reducing the probability of blade failure.

[0021] Optionally, the stirring portion further comprises a distance sensor, which is disposed at the first section and is used to detect a moving distance of the second section relative to the first section.

[0022] The distance sensor can monitor the moving distance of the second section relative to the first section in real time, thereby ensuring the precise position control of the stirring part during the stirring process. By obtaining the moving distance data of the second section relative to the first section, the stirring speed, stirring time and other parameters can be adjusted accordingly to optimize the stirring and extrusion process, which helps to reduce energy consumption and improve stirring efficiency.

[0023] Optionally, there are multiple blades in the blade group, and the multiple blades are arranged at intervals along the circumference of the stirring rod.

[0024] Multiple blades are arranged at intervals along the circumference of the stirring rod, which can ensure that stronger impact force and shear force are generated during the stirring process. The powder can be subjected to uniform stirring force or extrusion force in all directions, which helps the powder to reach a uniformly mixed state more quickly, thereby improving the stirring efficiency.

[0025] Optionally, there are multiple blade groups, and the multiple blade groups are arranged at intervals along the axial direction of the stirring rod.

[0026] There are multiple blade groups, which are spaced apart along the axial direction of the stirring rod. This can generate stronger shearing force and impact force, more effectively mix and stir the powder, so that the powder can be discharged from the first hole to the first discharge port, and more effectively promote the powder to flow in the containing cavity, reduce powder retention and dead corners, and ensure that the powder is evenly stirred and extruded.

[0043] With the acceleration of industrialization, powdered objects are increasingly used in many industries, such as chemicals, food, medicine, building materials, etc. These industries have high requirements for the handling and transportation of powders. Usually, a powder feeder is used to quantitatively supply powder. The powder first enters the feeding barrel, and then the stirring part squeezes and stirs the powder in the feeding barrel to make the powder out of the feeding barrel. The powder feeder stirs the powder by rotating the blades of the stirring part to squeeze and stir the powder.

[0044] However, in the related art, the blades of the stirring part are too large and are prone to collide with the barrel during installation, causing the barrel and the blades to be easily damaged.

[0045] In view of this, in order to solve the technical problem that the blades of the stirring part are too large and easily collide with the barrel during installation, resulting in the barrel and the blades being easily damaged, some embodiments of the present application provide a feeder, which includes a feeding barrel and a stirring part.

[0046] The feeding barrel has a accommodating chamber. 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, both of which are connected to the accommodating chamber. The stirring part is arranged in the accommodating chamber. Along the vertical direction, the stirring part is closer to the first discharge port than the first feed port, wherein the stirring part includes a stirring rod and a blade group, the blade group includes at least one blade, the blade is arranged on the stirring rod and extends radially along the stirring rod, and the size of the blade is adjustable along the radial direction of the stirring rod.

[0047] In the above scheme, the size of the blade is adjustable along the radial direction of the stirring rod, that is, the size of the blade can be changed along the radial direction of the stirring rod. When installing the feeder, the size of the blade in the radial direction of the stirring rod (the blade length) can be adjusted to make the blade length shorter, thereby reducing the probability of collision between the stirring part and the feeding bucket and improving the stability and reliability of the feeder. After the feeder is installed, the blade length can be adjusted to fit the inner wall of the feeding bucket, thereby increasing the range of the stirring part to squeeze and stir the powder.

[0048] For the convenience of description, the following embodiments are described by taking a feeder according to an embodiment of the present application as an example.

[0049] Please refer to Figures 1 to 4 , Figure 1 A schematic diagram of the structure of the feeder 100 provided in the embodiment of the present application when feeding; Figure 2 A schematic diagram of the structure of a feeder 100 provided in an embodiment of the present application; Figure 3 A schematic diagram of the structure of the sieve plate 190 provided in an embodiment of the present application; Figure 4 The structures of the first bump 140 and the second bump 141 are shown.

[0050] In an embodiment of the present application, the feeder 100 includes a feeding barrel 110 and a stirring portion 120, the feeding barrel 110 has a accommodating chamber 111, and along the vertical direction, the upper end and the lower end of the feeding barrel 110 respectively have a first feed port 112 and a first discharge port 113, the first feed port 112 and the first discharge port 113 are both connected to the accommodating chamber 111, the stirring portion 120 is arranged in the accommodating chamber 111, and along the vertical direction, the stirring portion 120 is closer to the first discharge port 113 than the first feed port 112, wherein the stirring portion 120 includes a stirring rod 121 and a blade group 122, the blade group 122 includes at least one blade 130, the blade 130 is arranged on the stirring rod 121 and extends along the radial direction of the stirring rod 121, and the size of the blade 130 is adjustable along the radial direction of the stirring rod 121.

[0051] The feeder 100 includes a feeder barrel 110, the feeder barrel 110 has a receiving chamber 111, the receiving chamber 111 is used to receive powder, and along the vertical direction, the upper end of the feeder barrel 110 is provided with a first feed port 112, and the lower end of the feeder barrel 110 is provided with a first discharge port 113, the powder is fed into the feeder 100 from the first feed port 112, and then discharged from the feeder 100 from the first discharge port 113, the first discharge port 113 can be provided with a sieve plate 190, the sieve plate 190 has a plurality of first holes 191, and the powder can be discharged from the sieve plate 190 through the first holes 191. 90. The aperture size of the first hole 191 can be set to be sufficient to prevent the powder from exiting the sieve plate 190 when it is stationary, while the powder can exit the first discharge port 113 from the first hole 191 when the powder is squeezed or stirred. In this way, on the one hand, the powder can be set in the accommodating chamber 111 when the feeder 100 is not working and will not leak out, while the powder can exit the first discharge port 113 from the first hole 191 when the feeder 100 is working. The feeder 100 can work stably and continuously, thereby improving production efficiency and reducing equipment failure rate and maintenance costs.

[0052] The feeder 100 further includes a stirring part 120, which is disposed in the accommodating chamber 111. In the vertical direction, the stirring part 120 is closer to the first discharge port 113 than the first feed port 112. The stirring part 120 is disposed between the first feed port 112 and the first discharge port 113, and the stirring part 120 is disposed at a position close to the first discharge port 113. Due to the effect of gravity, the powder enters the accommodating chamber 111 from the first feed port 112, and then exits the first discharge port 113 from the accommodating chamber 111. Therefore, by arranging the stirring part 120 at a position closer to the first discharge port 113 than the first feed port 112, the stirring part 120 can be in more sufficient contact with the powder, thereby improving the stirring efficiency of the stirring part 120, and the powder can more easily exit the first discharge port 113 and enter the target container 200.

[0053] The stirring portion 120 includes a stirring rod 121 and a blade group 122. Along the vertical direction, the length of the stirring rod 121 is parallel to the vertical direction. The blade group 122 includes at least one blade 130. The blade 130 is arranged on the stirring rod 121. The extension direction of the blade 130 is parallel to the radial direction of the stirring rod 121. Along the radial direction of the stirring rod 121, the size of the blade 130 is adjustable.

[0054] The size of the blade 130 of the stirring part 120 can be matched with the inner diameter of the feeding barrel 110. Therefore, when the stirring part 120 and the feeding barrel 110 are installed, the blade 130 of the stirring part 120 is easy to collide or rub with the feeding barrel 110, causing the feeding barrel 110 or the blade 130 to wear and reduce the service life of the feeder 100.

[0055] Specifically, the size of the blade 130 is adjustable along the radial direction of the stirring rod 121, that is, the size of the blade 130 can be changed along the radial direction of the stirring rod 121. When installing the feeder 100, the size of the blade 130 in the radial direction of the stirring rod 121 (the length of the blade 130) can be adjusted to make the length of the blade 130 shorter, reduce the probability of collision between the stirring part 120 and the feeding bucket 110, and improve the stability and reliability of the use of the feeder 100. After the feeder 100 is installed, the length of the blade 130 can be adjusted to fit the inner wall of the feeding bucket 110, so as to increase the range of the stirring part 120 to squeeze and stir the powder.

[0056] Along the radial direction of the stirring rod 121, the distribution range of different amounts of powder in the feeding barrel 110 is uneven. For example, when the amount of powder is small, the distribution range of the powder in the feeding barrel 110 is generally small. At this time, the length of the blade 130 can be adjusted to make the length of the blade 130 consistent with the distribution range of the powder. In this way, when the length of the blade 130 is small, the resistance of the blade 130 during rotation can be reduced, thereby improving the operating efficiency of the feeder 100 and reducing energy consumption.

[0057] In addition, since the radial dimension of the blade 130 in the stirring rod 121 is adjustable, a plurality of feeders 100 of different specifications can use the same stirring part 120 , thereby improving the adaptability of the stirring part 120 .

[0058] Please refer to Figures 1 to 4 In this embodiment, along the radial direction of the stirring portion 120 , the blade 130 includes a first section 131 and a second section 132 , the first section 131 is fixed to the stirring rod 121 , and the second section 132 is movably disposed on the first section 131 .

[0059] The blade 130 includes a first section 131 and a second section 132. The first section 131 is arranged on the stirring rod 121. The length direction of the first section 131 is parallel to the radial direction of the stirring rod 121. The first section 131 is fixed to the stirring rod 121. The second section 132 is movably arranged on the first section 131. The length direction of the second section 132 is parallel to the length direction of the first section 131.

[0060] The second section 132 is movably disposed on the first section 131, so that the stirring effect can be optimized according to the properties and distribution range of the powder, the operating efficiency of the feeder 100 can be improved, the probability of friction or collision between the second section 132 and the feeder 100 can be reduced, and the operating stability of the feeder 100 can be improved. In addition, if the second section 132 fails or wears out and needs to be replaced, only the first section 131 or the second section 132 can be replaced without replacing the entire blade 130, thereby reducing the repair or maintenance cost of the stirring part 120.

[0061] It can be understood that a locking portion is also provided between the first section 131 and the second section 132. After the second section 132 moves to a suitable position relative to the first section 131, for example, when the second section 132 moves to a feeding barrel 110 such that the radial dimension of the blade 130 on the stirring rod 121 meets specific specifications, the locking member can lock the second section 132 with the first section 131, thereby preventing the radial dimension of the blade 130 on the stirring rod 121 from changing during rotation.

[0062] Please refer to Figures 1 to 4 In this embodiment, along the radial direction of the agitating portion 120 , a first channel 131A is disposed in the first section 131 , and at least a portion of the second section 132 is disposed in the first channel 131A.

[0063] Along the radial direction of the stirring portion 120, a first channel 131A is provided in the first section 131, and the opening of the first channel 131A is radially oriented toward the stirring portion 120. At least a portion of the second section 132 extends into the first channel 131A through the opening of the first channel 131A. The second section 132 and the first end can be relatively displaced. Exemplarily, a movable rail can be provided on the second section 132, and a fixed rail can be provided on the first section 131. The extension directions of the movable rail and the fixed rail are parallel to the radial direction of the stirring portion 120, and the movable rail and the fixed rail cooperate with each other, so that the second section 132 and the first section 131 can be relatively displaced in the radial direction of the stirring portion 120, thereby realizing the adjustable size of the blade 130.

[0064] At least part of the second section 132 is disposed in the first channel 131A. On the one hand, it can reduce the overall size of the stirring portion 120 of the feeder 100, making the stirring portion 120 more compact as a whole and reducing the probability of collision or friction between the stirring portion 120 and the inner wall of the feeding barrel 110. On the other hand, the stirring path can be optimized by adjusting the position of the second section 132 in the first section 131, so that the powder and the stirring portion 120 can be stirred more fully and evenly.

[0065] Please refer to Figures 1 to 4 In this embodiment, a first protrusion 140 is disposed in the first channel 131A, and a second protrusion 141 is disposed on the second section 132. The first protrusion 140 is suitable for cooperating with the second protrusion 141 to limit the second section 132 from being separated from the first channel 131A.

[0066] The first protrusion 140 is arranged in the first channel 131A, that is, the first protrusion 140 is arranged on the inner side of the first section 131, the second protrusion 141 is arranged on the second section 132, the second protrusion 141 is arranged on the outer side of the second section 132, and the protruding portion of the second protrusion 141 can face the vertical direction, so that the first protrusion 140 and the second protrusion 141 are engaged with each other.

[0067] Specifically, the first protrusion 140 is adapted to cooperate with the second protrusion 141 to limit the second section 132 from being separated from the first channel 131A. The cooperation design of the first protrusion 140 and the second protrusion 141 can effectively prevent the second section 132 of the blade 130 from accidentally falling off due to excessive force during the mixing process, thereby improving the overall structural stability of the stirring part 120 and ensuring the continuous and stable operation of the feeder 100. Since the second section 132 of the blade 130 is effectively confined in the first channel 131A, it can provide a more stable shear force during the mixing process, which helps to break up the lumps and agglomerates of the powder and improve the dispersibility and fluidity of the powder.

[0068] Please refer to Figure 5 , Figure 5 The structure of the first spring 160 and the linear motor 150 is shown. In this embodiment, the stirring portion 120 further includes a first driving member, which is disposed in the first channel 131A and fixedly connected to the first section 131 , and a driving end of the first driving member is connected to the second section 132 .

[0069] The first driving member has a driving end, and the first driving member can drive the second section 132 to move so as to control the length of the blade 130 .

[0070] The first driving member is arranged in the first channel 131A and is fixedly connected to the first section 131. The driving end of the first driving member is connected to the second section 132. On the one hand, it can make the stirring portion 120 more compact and reduce the overall volume of the stirring portion 120. On the other hand, the first driving member directly drives the second section 132, which reduces the intermediate transmission links and improves the stability and reliability of the drive.

[0071] Please refer to Figure 5 In this embodiment, the first driving member is configured as a linear motor 150 , and a driving shaft 151 of the linear motor 150 is fixedly connected to the second section 132 .

[0072] The first driving member is constructed as a linear motor 150, and the driving shaft 151 of the linear motor 150 is fixedly connected to the second section 132. The linear motor 150 can achieve high-precision position control and speed control, and can more accurately control the position of the second section 132, thereby controlling the length of the blade 130, and reducing the probability of collision between the blade 130 and the inner wall of the feeding bucket 110. Moreover, the linear motor 150 can start and stop responding quickly, and quickly adjust the stirring speed and direction of the blade 130. This rapid response capability helps to achieve more flexible stirring strategies during powder transmission.

[0073] Please refer to Figure 5 In this embodiment, the stirring portion 120 further includes a first spring 160 , one end of the first spring 160 is connected to the second section 132 , and the other end of the first spring 160 is connected to the first section 131 .

[0074] During the stirring process, along the radial direction of the stirring part 120, the powder may generate a large impact force at one end of the second section 132, causing damage to the stirring part 120. The first spring 160 can play a role of buffering and shock absorption, effectively absorbing these impact forces, and protecting the stirring part 120 from damage. The first spring 160 can reduce the energy consumption during the stirring process. When the second section 132 is subjected to the resistance of the powder, the first spring 160 will absorb and store part of the energy, and then release this part of the energy when the second section 132 rebounds. This energy recovery mechanism helps to reduce the energy consumption of the equipment and improve the energy efficiency ratio.

[0075] Please refer to Figure 6 , Figure 6 The structure of the sealing part 170 is shown. In this embodiment, the sealing part 170 is provided on the inner wall of the first channel 131A, and the sealing part 170 is interference fit with the second section 132, and the sealing part 170 is configured as an elastic member.

[0076] The interference fit between the sealing portion 170 and the second section 132 ensures close contact between the two, thereby effectively preventing the powder from entering the first channel 131A or the first section 131 during the stirring process, and reducing the probability of failure of the blade 130. Moreover, since the sealing portion 170 is configured as an elastic member, it can adapt to different pressure changes to a certain extent. During the stirring process, when the powder exerts pressure on the stirring portion 120, the sealing portion 170 can undergo slight elastic deformation, thereby maintaining close contact between the first section 131 and the second section 132, and preventing powder leakage.

[0077] Please refer to Figure 7 , Figure 7 The structure of the distance sensor 180 is shown. In the present embodiment, the agitating portion 120 further includes the distance sensor 180 , which is disposed at the first section 131 and is used to detect the moving distance of the second section 132 relative to the first section 131 .

[0078] The distance sensor 180 can monitor the moving distance of the second section 132 relative to the first section 131 in real time, so as to ensure the precise position control of the stirring part 120 during the stirring process. By obtaining the moving distance data of the second section 132 relative to the first section 131, the stirring speed, stirring time and other parameters can be adjusted accordingly to optimize the stirring and extruding process, which helps to reduce energy consumption and improve stirring efficiency. Moreover, by monitoring the moving distance of the second section 132, it is possible to timely detect whether the stirring part 120 is excessively worn or abnormally moved. Once an abnormality is found, measures can be taken immediately, such as stopping the machine for inspection or adjusting the stirring parameters, to prevent equipment damage or safety accidents.

[0079] Please refer to Figures 1 to 7 In the present embodiment, there are a plurality of blades 130 in the blade assembly 122 , and the plurality of blades 130 are arranged at intervals along the circumference of the stirring rod 121 .

[0080] The plurality of blades 130 are arranged at intervals along the circumference of the stirring rod 121, which can ensure that during the stirring process, stronger impact force and shear force are generated, and the powder can be subjected to uniform stirring force or extrusion force in all directions, which helps the powder to reach a uniform mixing state more quickly, thereby improving the stirring efficiency. The interval arrangement of the blades 130 can also reduce the aggregation of powder during the stirring process. When the blades 130 rotate, the plurality of blades 130 can disperse the aggregated powder, thereby avoiding the formation of dead corners or accumulation areas of powder in the stirring barrel.

[0081] Please refer to Figures 1 to 7 In the present embodiment, there are a plurality of blade groups 122 , and the plurality of blade groups 122 are arranged at intervals along the axial direction of the stirring rod 121 .

[0082] There are multiple blade groups 122, and the multiple blade groups 122 are arranged at intervals along the axial direction of the stirring rod 121. It can generate stronger shear force and impact force, more effectively mix and stir the powder, so that the powder can be discharged from the first hole 191 to the first discharge port 113, and it can more effectively promote the powder to flow in the accommodating cavity 111, reduce powder retention and dead corners, and ensure that the powder is evenly stirred and extruded.

[0083] Moreover, the plurality of blade groups 122 are arranged at intervals along the axial direction of the stirring rod 121, which can ensure that the powder is more fully stirred and extruded during the stirring process. Each blade group 122 can stir and extrude the powder to a certain extent, and the synergistic effect of the plurality of blade groups 122 can make the powder reach a more uniform mixing state in all directions.
