Description

Technical Field

[0001] This utility model relates to the field of integral molding equipment, and more specifically, to a powder supply device for an integral molding equipment for inductors. Background Technology

[0002] Inductors are crucial electronic components in the electronics industry, commonly used energy storage elements in various high-current electronic circuits. The most widely used inductor is the high-current integrated inductor, which is formed by die-casting iron powder with a coil wound with round copper wire in a single process using a special technique. The most common method is processing using integrated hot-pressing equipment. The iron powder feeding device is the first stage of the process. Current feeding devices use rollers to distribute the material, achieving the required quantitative dispensing effect. While relatively common, this method still has significant drawbacks, such as susceptibility to clogging, insufficient or uneven feeding, and even incomplete feeding, all of which affect the quality of subsequent processing and forming. Therefore, improvements are needed. Utility Model Content

[0003] In order to overcome the defects of the prior art, the technical problem to be solved by this utility model is to propose a powder supply device for an inductive integrated molding equipment, which can effectively agitate the material and provide a vibration effect to ensure that the material trough is completely filled with material; and the vibration can also ensure complete material feeding.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] This utility model provides a powder supply device for an inductor integrated molding equipment, including a hopper. The bottom of the hopper is provided with a strip-shaped discharge port, and a discharge roller for quantitative discharge is installed at the discharge port. An agitation mechanism is installed on the inner side of the bottom of the hopper to agitate the material collected at the bottom of the hopper and make the material evenly distributed. A vibration motor is installed on the outer side of the bottom of the hopper to promote the material to enter the material groove of the discharge roller and form a uniform compaction effect, and also to promote the complete discharge of material from the discharge roller.

[0006] In a preferred embodiment of this invention, the stirring mechanism includes a motor, a first spiral stirring shaft, and a second spiral stirring shaft.

[0007] The first and second spiral mixing shafts are rotatably mounted on the bottom of the hopper via bearing seats, located above the feeding roller, and symmetrically arranged about the feeding roller; both the first and second spiral mixing shafts are driven to rotate by a motor, and the two push materials in opposite directions.

[0008] In the preferred embodiment of this invention, the feeding roller is driven to rotate by a motor and rotates only in a single direction.

[0010] In a preferred embodiment of this invention, the edges of the blades of both the first and second spiral stirring shafts are provided with notches, which are evenly spaced along the direction of the blades.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 5 As shown in the figure, a powder supply device for an inductor integrated molding equipment is disclosed in a specific embodiment of the present invention, including a hopper 100, a strip-shaped discharge port 110 at the bottom of the hopper 100, and a discharge roller 200 for quantitative discharge installed at the discharge port 110; an agitation mechanism 300 is installed on the inner side of the bottom of the hopper 100 to agitate the material collected at the bottom of the hopper so that the material is evenly distributed; a vibration motor 400 is installed on the outer side of the bottom of the hopper 100 to promote the material to enter the trough of the discharge roller and form a uniform compaction effect, and also to promote the complete discharge of material by the discharge roller.

[0025] The powder supply device for the aforementioned inductor integrated molding equipment includes an agitation mechanism for agitating the material gathered at the bottom of the hopper, so that the material is evenly distributed and can smoothly enter the trough, preventing accumulation and blockage.

[0026] A vibration motor is installed on the outer bottom of the hopper to encourage the material to enter the trough of the feeding roller and form a uniform compaction effect, so that the compaction is consistent, which means that the amount of material is relatively consistent; the vibration can also be used to ensure that the feeding roller discharges the material completely, realizes emptying, and reduces feeding errors.

[0027] Furthermore, such as Figure 4 As shown, the stirring mechanism 300 includes a motor 330, a first spiral stirring shaft 310, and a second spiral stirring shaft 320. The first spiral stirring shaft 310 and the second spiral stirring shaft 320 are rotatably mounted on the bottom of the hopper via bearing seats, located above the feed roller 200, and are symmetrically arranged about the feed roller. Both the first spiral stirring shaft 310 and the second spiral stirring shaft 320 are driven to rotate by the motor 330, and the two push materials in opposite directions. Through the opposite pushing action of materials, the materials can be moved back and forth, effectively preventing blockage, and also allowing the materials to fully enter the trough, achieving effective filling.

[0028] Furthermore, the bottom of the hopper narrows from both sides towards the middle, forming a discharge port at the narrowing part. The discharge roller is located at the discharge port, while the first and second spiral stirring shafts are located above the discharge port and above the inclined walls on both sides of the bottom of the hopper, effectively stirring the material gathered at the bottom so that the material can smoothly enter the trough.

[0029] Furthermore, the feeding roller 200 is driven to rotate by the motor 330, and rotates only in one direction; this allows the feeding roller, the first spiral stirring shaft, and the second spiral stirring shaft to share the same motor, reducing the use of electrically driven equipment, lowering costs, and reducing the probability of damage; the unidirectional rotation of the feeding roller allows for better control of the feeding action and facilitates subsequent design for coordination with the first and second spiral stirring shafts; the feeding roller is equipped with two material grooves arranged in a circumferential array about the axis, and the feeding roller slides close to the inner wall of the feeding port. When the feeding roller rotates, only a single material groove is aligned and connected with the outlet of the feeding port, ensuring quantitative feeding;

[0030] Furthermore, one end of the shaft of the first spiral stirring shaft 310 and the second spiral stirring shaft 320 is driven by gear 340.

[0031] The other end of the first spiral stirring shaft 310 is connected to the output shaft of the motor 330 via the first synchronous belt pulley assembly 510; thus, both the first and second spiral stirring shafts are driven by the motor, and the materials are pushed in opposite directions, achieving the effect of effectively stirring the materials.

[0032] like Figure 3 , Figure 4 As shown, a one-way bearing 210 is installed on the shaft of the feeding roller 200 near the motor. The one-way bearing 210 is connected to the shaft of the second spiral stirring shaft 320 through a second synchronous belt pulley assembly 520. The one-way bearing is used to distinguish whether the feeding roller is driven. More specifically, when the motor rotates forward, it only drives the first and second spiral stirring shafts to rotate, and the feeding roller does not rotate, thus maintaining the blockage of the feeding port. Conversely, when the motor rotates in reverse, the first and second spiral stirring shafts still rotate to agitate the material, but in the opposite direction. This direction can drive the one-way bearing to rotate, thereby driving the feeding roller to rotate to the required angle, so that the material trough containing the material swings down to the bottom, realizing the feeding.

[0033] Furthermore, the hopper includes two opposing first support plates, with a second support plate fixed between them by bolts. The bottoms of the two second support plates are bent towards one side to form a downwardly narrowing bucket-shaped structure, and an arc-shaped groove is provided at the bottom. The two arc-shaped grooves form a discharge port, the shape of which matches the shape of the discharge roller, limiting the material to be discharged only through the trough. The width of the first support plate matches the top width of the second support plate, and the bottom of the first support plate is bent inward to create a gap in the second support plate for installing the motor. The whole structure is an assembly type, which facilitates the processing and production of each component, as well as the installation of the internal first spiral stirring shaft, second spiral stirring shaft, and discharge roller, and facilitates the overall assembly.

[0034] Furthermore, such as Figure 5 As shown, the edges of the blades of the first spiral stirring shaft 310 and the second spiral stirring shaft 320 are provided with notches 350, and the notches are evenly spaced along the direction of the blades; the notches serve as the parts where materials intersect or overflow, ensuring that the materials can flow and further disturb the materials for mixing.

[0035] Furthermore, the bottom of the hopper 100 is provided with two outer sides corresponding to the discharge port, and a thin-walled structure is formed near the discharge port. The vibrating motor 400 is installed in the trough 120. Furthermore, two vibrating motors are installed in one trough, and the four vibrating motors are evenly spaced along the length of the discharge port. Preferably, the vibrating motors in the two troughs are staggered and spaced, so that the vibration is more gentle and the vibration range is larger, which effectively promotes the material to fall out of the lower trough and also promotes the material to enter the upper trough smoothly.

[0036] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
