Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a powder mixing equipment. Background Technology

[0002] In the manufacturing process of magnetic cores, powder mixing equipment is a crucial piece of equipment that can uniformly mix various raw material powders to ensure that the subsequently manufactured magnetic cores have good appearance and physical properties. During the process of production personnel pouring raw material powder into the powder mixing equipment through the feeding channel, some powder will adhere to and remain on the feeding channel. This powder adhering to the feeding channel may suddenly detach at some point and enter the mixing area of ​​the powder mixing equipment, resulting in insufficient mixing time with other powders. This leads to uneven powder mixing and hinders the improvement of the mixing efficiency of the powder mixing equipment. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a powder mixing device that can improve the mixing effect of powders.

[0004] A powder mixing device according to an embodiment of the present invention includes a frame, a drum, a feeding pipe, a rotary drive device, and an air blowing device. The drum is rotatably connected to the frame and is used to hold powder. A first baffle plate is rotatably connected to the inlet of the drum to seal the inlet. The feeding pipe is slidably connected to the frame so that its lower end can extend into or exit the inlet of the drum. A funnel is provided at the upper end of the feeding pipe for pouring powder into the drum. The rotary drive device drives the drum to rotate, thereby agitating the powder. The air blowing device is located between the feeding pipe and the funnel and blows air into the feeding pipe to blow powder adhering to the inner wall of the feeding pipe into the drum.

[0005] It has at least the following beneficial effects:

[0006] When powder needs to be mixed, the production operator can rotate the first baffle on the drum to open the drum's inlet. Next, the operator can move the feeding pipe so that its lower end is close to the drum's inlet and extends into it. The operator can then pour the powder to be mixed into the funnel at the upper end of the feeding pipe, allowing it to enter the drum. After the powder in the funnel has completely entered the feeding pipe, the operator can activate the air blowing device, which blows air into the feeding pipe, causing any powder adhering to the inner wall of the pipe to be blown into the drum. The operator then closes the air blowing device and moves the feeding pipe away from the drum's inlet, pulling it out of the inlet. Finally, the operator rotates the first baffle to seal the drum's inlet. After the first baffle seals the feed inlet of the roller, the production personnel activate the rotary drive device, which drives the roller to rotate, thus agitating the powder and achieving a homogenizing effect. Under the action of the air blowing device, the powder adhering to the feeding channel is completely blown into the roller. During the roller's agitation process, the first baffle seals the feed inlet, eliminating the possibility of external powder entering the roller and ensuring that the powder inside the roller does not mix with external powder. This ensures sufficient mixing time for the powder inside the roller, thereby improving the homogenization effect.

[0007] According to the powder mixing device of this utility model embodiment, the air blowing device includes a transfer pipe and a plurality of air nozzles. The transfer pipe is disposed between the feeding pipe and the funnel. The funnel is connected to the feeding pipe through the transfer pipe. The plurality of air nozzles are arranged in a circumferential array on the inner wall of the transfer pipe. The plurality of air nozzles are all inclined and facing the feeding pipe so that the gas ejected by the plurality of air nozzles can be blown into the feeding pipe.

[0008] The powder mixing device according to an embodiment of the present utility model further includes a support, the support being slidably connected to the frame, and the feeding pipe being disposed on the support and slidably connected to the frame through the support.

[0009] According to the powder mixing device of this utility model embodiment, the support is provided with a first locking assembly, and the support can be locked onto the frame by the first locking assembly.

[0010] According to the powder mixing equipment of this utility model embodiment, the rotary drive device includes a gearbox, a rotary drive component, and a gear ring. The gearbox and the rotary drive component are both mounted on the frame. The gear ring is sleeved on the outer wall of the drum. The output end of the rotary drive component is connected to the gear ring through the gearbox, so that the rotary drive component can drive the drum to rotate.

[0011] The powder mixing equipment according to an embodiment of the present invention further includes a spraying device, which is disposed on the frame and has its spraying end extending into the drum. The spraying device is used to spray a mist-like solution into the drum.

[0012] The powder mixing device according to an embodiment of the present invention further includes a discharge shell, which is disposed on the frame. The discharge port of the roller extends into the discharge shell. A guide pipe is provided at the lower end of the discharge shell, which is connected to the discharge shell and is parallel to the vertical direction.

[0013] The powder mixing device according to an embodiment of the present invention further includes a second shielding plate, which is rotatably connected to the lower end of the feed pipe and can shield the lower end of the feed pipe.

[0014] The powder mixing equipment according to an embodiment of the present invention further includes a sieving device, which is located below the feed pipe so that the powder in the feed pipe can fall into the sieving device, and the sieving device is used to sieve the powder.

[0025] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] Reference Figure 1 and Figure 2 This utility model discloses a powder mixing device, including a frame 300, a drum 100, a feeding pipe 210, a rotary drive device (not shown in the figure) and an air blowing device 220.

[0029] A roller 100 is rotatably connected to a frame 300. The roller 100 is used to hold powder. A first baffle plate 110 is rotatably connected to the inlet of the roller 100 to seal the inlet of the roller 100. A feeding pipe 210 is slidably connected to the frame 300 so that the lower end of the feeding pipe 210 can extend into or out of the inlet of the roller 100. A funnel 230 is provided at the upper end of the feeding pipe 210 for pouring powder into the roller 100. A rotary drive device is used to drive the roller 100 to rotate so that the roller 100 can stir the powder. An air blowing device 220 is located between the feeding pipe 210 and the funnel 230. The air blowing device 220 is used to blow air into the feeding pipe 210 so that the powder adhering to the inner wall of the feeding pipe 210 can be blown into the roller 100.

[0030] In this embodiment of the invention, the axis of the drum 100 is parallel to the front-to-back direction. The rotary drive device is mounted on the frame 300. The rotary drive device can drive the drum 100 to rotate clockwise around its own axis, so that the drum 100 can agitate the powder inside. The inner wall of the drum 100 is provided with lifting plates, spiral guide vanes, and lifting plates. When the rotary drive device drives the drum 100 to rotate clockwise, the lifting plates, spiral guide vanes, and lifting plates rotate clockwise with the drum 100. The lifting plates can lift the powder and raise it to a certain height, and then the powder falls freely under the action of gravity, realizing the up-and-down tumbling and mixing of the powder. The spiral guide vanes can make the powder form a spiral flow inside the drum 100 to enhance the mixing effect. The lifting plates can lift the powder, making the powder form a scattered shape inside the drum 100, increasing the contact area between the powder and the air, and promoting the full mixing of powder in different parts, thus strengthening the mixing effect. The rotary drive device can drive the drum 100 to rotate in reverse around its own axis, and the lifting plates, spiral guide vanes, and material lifting plates rotate in reverse along with the drum 100. The lifting plates can push the powder towards the discharge port of the drum 100 to assist in the discharge of the powder; the spiral guide vanes can change the flow direction of the powder, so that the powder moves towards the discharge port of the drum 100 along the spiral direction to achieve efficient discharge of the powder; the material lifting plates can also play a certain pushing role to help the powder move towards the discharge port of the drum 100.

[0031] In this embodiment of the invention, the feeding pipe 210 can move along the front-back direction on the frame 300, allowing the lower end of the feeding pipe 210 to approach or move away from the feed inlet of the drum 100, thereby allowing the lower end of the feeding pipe 210 to extend into or exit from the feed inlet of the drum 100. A first baffle plate 110 is rotatably connected to the drum 100 and is positioned at the feed inlet of the drum 100. The first baffle plate 110 can seal the feed inlet of the drum 100 during the mixing of powder in the drum 100 to prevent powder from flying out. The first baffle plate 110 can also open the feed inlet of the drum 100 during feeding to ensure that powder can smoothly enter the drum 100 through the feeding pipe 210. The upper end of the feeding pipe 210 is provided with a funnel 230 that communicates with the feeding pipe 210. The funnel 230 shrinks from top to bottom, so that the funnel 230 can guide the poured powder and ensure that all the powder can enter the feeding pipe 210.

[0032] Understandably, when it is necessary to mix the powder, the production operator can rotate the first baffle 110 on the roller 100 to open the feed inlet of the roller 100. Then, the production operator can move the feeding pipe 210 so that its lower end is close to the feed inlet of the roller 100 and extends into the feed inlet. The production operator can then pour the powder to be mixed into the funnel 230 at the upper end of the feeding pipe 210, allowing the powder to enter the roller 100 through the feeding pipe 210. After the powder in the funnel 230 has completely entered the feeding pipe 210, the production operator can turn on the air blowing device 220, which blows air into the feeding pipe 210, causing the powder adhering to the inner wall of the feeding pipe 210 to be blown into the roller 100. Next, the production personnel turn off the air blowing device 220 and move the feeding pipe 210 so that the lower end of the feeding pipe 210 is away from the feed inlet of the roller 100, and pull the lower end of the feeding pipe 210 out of the feed inlet of the roller 100. Then, the production personnel rotate the first baffle plate 110 to seal the feed inlet of the roller 100. After the first baffle plate 110 seals the feed inlet of the roller 100, the production personnel turn on the rotary drive device so that the rotary drive device can drive the roller 100 to rotate, thereby enabling the roller 100 to stir the powder and achieve the effect of mixing the powder. Under the action of the air blowing device 220, the powder adhering in the feeding channel can be completely blown into the drum 100. During the mixing process of the drum 100, the first baffle plate 110 seals the feed inlet of the drum 100, eliminating the possibility of external powder entering the drum 100 during the mixing process. This ensures that the powder inside the drum 100 will not mix with external powder, ensuring that the powder inside the drum 100 has sufficient mixing time, which is conducive to improving the mixing effect of the powder.

[0033] refer to Figure 1 , Figure 2 and Figure 4The blowing device 220 includes a transfer pipe 221 and multiple air nozzles 222. The transfer pipe 221 is located between the upper end of the feeding pipe 210 and the funnel 230. The funnel 230 is connected to the feeding pipe 210 through the transfer pipe 221. The multiple air nozzles 222 are arranged in a circular array on the inner wall of the transfer pipe 221, and all the air nozzles 222 are inclined and facing the feeding pipe 210 so that the gas ejected by the multiple air nozzles 222 can be blown into the feeding pipe 210. It can be understood that the multiple air nozzles 222 are arranged in a circular array on the inner wall of the transfer pipe 221 around the axis of the transfer pipe 221, and all the air nozzles 222 are inclined downwards. After the production personnel pour the powder into the funnel 230, the powder in the funnel 230 will enter the drum 100 in sequence through the transfer pipe 221 and the feeding pipe 210 under its own gravity, thus completing the feeding of the powder. After the powder in the funnel 230 enters the drum 100, the production personnel activate the air blowing device 220, causing multiple air nozzles 222 to simultaneously spray gas into the feeding pipe 210. This allows the sprayed gas to blow the powder adhering to the inner wall of the feeding pipe 210 into the drum 100. In this embodiment, the air blowing device 220 can be activated before the production personnel pour the powder into the funnel 230, causing the multiple air nozzles 222 to continuously spray gas downwards at an angle. After the air blowing device 220 is activated, the production personnel then pour the powder to be mixed into the funnel 230. It is understood that during the process of the powder passing through the transfer pipe 221, the gas sprayed from the multiple air nozzles 222 acts on the powder, causing the sprayed gas to disperse any clumps in the powder. In other words, the multiple air nozzles 222 pre-disperse the powder to be mixed, which helps to achieve more uniform mixing in the subsequent mixing process, improving the mixing effect of the powder mixing equipment. In this embodiment of the invention, the blowing device 220 further includes an air pump, which is connected to a plurality of air nozzles 222 so that the plurality of air nozzles 222 can eject gas, which will not be described further here.

[0034] refer to Figure 1 and Figure 2The powder mixing equipment also includes a support 200, which is slidably connected to the frame 300. A feeding pipe 210 is located on the support 200 and is slidably connected to the frame 300 via the support 200. It is understood that the support 200 can be slidably connected to the frame 300 in the front-to-back direction, and the feeding pipe 210 is connected to the support 200. Production personnel can move the support 200 to bring the feeding pipe 210 closer to or further away from the feed inlet of the roller 100. The funnel 230 and the transfer pipe 221 are also connected to the support 200, allowing the support 200 to support the funnel 230 and the transfer pipe 221. In this embodiment of the utility model, the frame 300 is provided with two slide rails parallel to the front-back direction, and the support 200 is provided with four sliders, two of which are slidably connected to one of the slide rails, and the other two sliders are slidably connected to the other slide rail, thereby enabling the support 200 and the feeding pipe 210, the transfer pipe 221 and the funnel 230 on the support 200 to move on the frame 300.

[0035] In this embodiment of the invention, the support 200 is provided with a first locking assembly 240, which allows the support 200 to be locked onto the frame 300. It is understood that when powder needs to be added to the roller 100, the operator moves the support 200 so that the lower end of the feeding pipe 210 extends into the feed inlet of the roller 100. Then, the operator can manipulate the first locking assembly 240 on the support 200 to lock the support 200 securely onto the frame 300, thus preventing the feeding pipe 210 and funnel 230 from moving during the powder addition process, ensuring smooth feeding. After feeding is completed, the production operator can manipulate the first locking assembly 240 to loosen the support 200, allowing the operator to move the support 200 and thus pull the lower end of the feeding pipe 210 out of the feed inlet of the roller 100. Then, the operator rotates the first baffle plate 110 to seal the feed inlet of the roller 100. In this embodiment, the first locking assembly 240 is a common flat-mouth hook-and-loop fastener. The fastener is mounted on the support 200, and the fastener body is mounted on the frame 300. The fastener engages with the fastener body to lock the support 200 securely to the frame 300. Other locking mechanisms are also possible, which will not be further described here.

[0036] refer to Figure 1 and Figure 2The first baffle plate 110 is equipped with a second locking assembly 120, which locks the first baffle plate 110 onto the drum 100. This means that after powder is added, the first baffle plate 110 is locked onto the drum 100 by the second locking assembly 120, preventing the first baffle plate 110 from opening the feed inlet of the drum 100 during mixing. When powder needs to be added to the drum 100, the production operator can operate the second locking assembly 120 to release the first baffle plate 110, allowing it to rotate and open the feed inlet of the drum 100. The second locking assembly 120 has the same structure as the first locking assembly 240, and will not be described further here. In one embodiment of this utility model, a vibrator is provided on the support 200. The output end of the vibrator is connected to the feeding pipe 210. The vibrator is used to drive the feeding pipe 210 to vibrate, so that the powder adhering to the inner wall of the feeding pipe 210 can fall into the drum 100. It can be understood that the vibrator can accelerate the removal of powder adhering to the inner wall of the feeding pipe 210, so that all the adhering powder can enter the drum 100. Under the combined action of the vibrator and the air blowing device 220, the possibility of powder adhering to the feeding pipe 210 is further reduced.

[0037] In this embodiment of the invention, the rotary drive device includes a gearbox, a rotary drive component, and a gear ring. Both the gearbox and the rotary drive component are mounted on the frame 300. The gear ring is fitted onto the outer wall of the drum 100. The output end of the rotary drive component is connected to the gear ring via the gearbox, enabling the rotary drive component to drive the drum 100 to rotate. It is understood that the rotary drive component can be a motor. The output end of the rotary drive component is connected to the input end of the gearbox, and the output end of the gearbox meshes with the gear ring on the outer wall of the drum 100, allowing the rotary drive component to drive the drum 100 to rotate forward or backward via the gearbox. It should be noted that the gearbox, also called a transmission, mainly consists of gears, shafts, bearings, and a housing. The output end of the rotary drive component is connected to the input gear inside the gearbox, and the output gear inside the gearbox meshes with the gear on the outer wall of the drum 100. The gearbox is a common transmission device and will not be further elaborated here.

[0038] refer to Figure 1 and Figure 2The powder mixing equipment also includes a spraying device 350, which is mounted on the frame 300. The spraying end of the spraying device 350 extends into the drum 100, and the spraying device 350 is used to spray a mist of solution into the drum 100. In this embodiment of the invention, the solution is a coupling agent. It is understood that during the mixing of powder in the drum 100, the spraying device 350 can spray a mist of coupling agent into the drum 100. The coupling agent can reduce the surface energy of the powder particles, reduce the agglomeration of powder particles, and make the powder more evenly dispersed and mixed in the drum 100. At the same time, the coupling agent can also form a thin separating film between the powder and the inner wall of the drum 100, reducing the adhesion between the powder and the inner wall of the drum 100, preventing the powder from adhering to the inner wall of the drum 100, and helping to improve the mixing efficiency of the drum 100. The coupling agent is a commonly used solution in the field of magnetic core manufacturing, and will not be further described here. In this embodiment of the invention, the spraying device 350 includes a delivery pipe, a storage tank, a heating component, a pressure pump, and multiple nozzles. The storage tank is mounted on the frame 300 and contains a solution. The heating component heats the solution in the storage tank. One end of the delivery pipe is connected to the storage tank, and the other end extends into the drum 100. Multiple nozzles are evenly distributed on the other end of the delivery pipe and connected to it. It is understood that during the mixing of powder in the drum 100, the heating component heats the solution stored in the storage tank. Then, the pressure pump uses compressed air to send the solution from the storage tank into the delivery pipe. The solution in the delivery pipe is then sprayed out in a mist form from the multiple nozzles under pressure. The spraying device 350 is a common atomizing spraying device, which will not be further described here. In this embodiment of the invention, the delivery pipe extends into the drum 100 through the discharge port and does not rotate with the drum 100.

[0039] refer to Figures 1 to 3The powder mixing equipment also includes a discharge housing 310, which is mounted on the frame 300. The discharge port of the roller 100 extends into the discharge housing 310. A guide pipe 320 is provided at the lower end of the discharge housing 310, communicating with the discharge housing 310 and parallel to the vertical direction. After the powder is mixed, the production personnel can place the container for holding the powder below the guide pipe 320. Then, the production personnel operate the rotary drive device to reverse the roller 100, causing the powder inside the roller 100 to be discharged from the discharge port under the action of the lifting plates, spiral guide vanes, and lifting plates. The powder discharged from the discharge port of the roller 100 enters the discharge housing 310, and then falls into the container through the guide pipe 320, completing the collection of the powder. The powder mixing equipment also includes a second baffle plate 340, which is rotatably connected to the lower end of the feed pipe 320. The second baffle plate 340 can block the lower end of the feed pipe 320. Understandably, after collecting the powder, the production personnel can rotate the second baffle plate 340 to block the lower end of the feed pipe 320, and then move the receiving box away to prevent residual powder in the feed pipe 320 from falling into the operating environment outside the receiving box, thus ensuring a clean operating environment. When discharge is required, the production personnel can rotate the second baffle plate 340 to open the lower end of the feed pipe 320, allowing the powder to fall into the receiving box through the feed pipe 320.

[0040] refer to Figures 1 to 3 The powder mixing equipment also includes a sieving device 330, which is located below the feed pipe 320 so that the powder in the feed pipe 320 can fall into the sieving device 330. The sieving device 330 is used to sieve the powder. It can be understood that after the powder is mixed, the drum 100 reverses to discharge, allowing the powder in the drum 100 to fall into the sieving device 330 through the discharge housing 310 and the feed pipe 320. The sieving device 330 sieves the mixed powder, classifying it according to particle size and collecting powder of different sizes. Powder that meets the size requirements can enter subsequent processes, while coarse or fine powder that does not meet the requirements can be returned to the drum 100 or subjected to other processing, ensuring a uniform particle size distribution of the powder used to manufacture the magnetic core and improving the quality of the magnetic core. The screening device 330 is a common device used for screening powder materials, and its specific structure will not be described in detail here.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
