Description

Technical Field

[0001] This application relates to the field of feeding mechanism technology, and in particular to a silicon powder feeder with stirring function. Background Technology

[0002] To ensure that the product achieves the desired performance, various raw materials need to be mixed in a set ratio. In the existing technology, silicon powder needs to be weighed, but whether it is weighing or measuring volume, it must be done separately each time, making it difficult to increase the feeding speed. Summary of the Invention

[0003] The purpose of this application is to provide a silicon powder feeder with high feeding accuracy and faster speed.

[0004] To achieve the above objectives, this application provides a silicon powder feeder with a stirrer: It includes a frame, on which a body and a geared motor are fixedly connected. The body includes a feeding cylinder, inside which a guide cylinder is fixedly connected. A distributing roller is rotatably connected inside the guide cylinder. The guide cylinder has an inlet at its top and a outlet at its bottom. The outer side of the distributing roller has a partition groove suitable for communicating with the inlet or outlet. The partition groove is also suitable for being completely blocked by the inner wall of the guide cylinder. The end of the distributing roller has an end shaft suitable for passing through the guide cylinder and connecting to the output end of the geared motor. The top of the feeding cylinder has a storage bin, and the side wall of the storage bin is equipped with a stirring mechanism for mixing the silicon powder (the main material) with other raw materials and applying an additional downward force to the material.

[0005] As a preferred embodiment, the stirring mechanism includes a motor and a reducer fixedly connected to the outer side of the storage silo. The output end of the reducer is fixedly connected to a drive shaft, and the portion of the drive shaft extending into the storage silo has a stirring rod, which is the main component for stirring the material.

[0006] As a preferred embodiment, the side wall of the storage silo is provided with a longitudinal shaft hole for the drive shaft to pass through and form a rotating pair. The inner wall of the opposite side wall of the storage silo is fixedly connected with a bushing, which is suitable for cooperating with the end of the drive shaft to form a rotating pair and to restrict the degree of freedom of movement of the drive shaft.

[0007] As a preferred embodiment, the side wall of the feeding cylinder is provided with a configuration hole, the guide cylinder is fixedly connected to the configuration hole, and the top of the storage bin is provided with a cover to prevent debris from entering the storage bin.

[0008] As a preferred embodiment, the frame includes a tray with a fitting groove, and the bottom of the feed cylinder has a funnel adapted to be embedded in the fitting groove to restrict the position of the machine body relative to the frame.

[0009] As a preferred embodiment, the upper surface of the pallet has a bracket, the geared motor is fixedly connected to the bracket, and the bracket has a horizontal shaft hole for the end shaft to pass through to form a rotating pair, which can improve the stability of the end shaft rotation.

[0010] As a preferred embodiment, the upper surface of the pallet has a pair of supports, the machine body is located between the two supports, and both ends of the distributing roller have end shafts, which are suitable for cooperating with the two supports to form a rotating pair, thereby further improving the stability of the distributing roller rotation.

[0011] As a preferred embodiment, there are two reducers, and the output ends of the two reducers are respectively connected to a drive shaft. The two drive shafts rotate in opposite directions, and their relative rotation allows for better application of downward pressure.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By setting a tightly fitted guide tube and distribution roller structure in the feeding cylinder, and with a stirring mechanism that can apply downward pressure, the feeder can feed material downward in a specific volume. Compared with the weighing method, the feeding speed is faster and the efficiency is higher.

[0014] (2) By setting a stirring structure in the storage bin, not only can the raw materials be premixed, but also additional downward pressure can be applied to the material in the storage bin, so that the material entering the partition groove on the distributing roller is compacted, thereby ensuring that the amount of material taken out each time is very consistent and ensuring the feeding accuracy.

[0024] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application 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. They should not be construed as limiting the specific protection scope of this application.

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0028] like Figure 1-8The silicon powder feeder with stirring shown includes a fixed frame 1, on which a body 2 and a geared motor 3 are fixedly connected. The body 2 includes a feeding cylinder 202 with its axis horizontal. The frame 1 includes a support plate 101 with a fitting groove 102 in the center. The bottom of the feeding cylinder 202 has a funnel 206, which is connected to the inside of the feeding cylinder 202. The funnel 206 is fitted into the fitting groove 102. The lower end of the funnel 206 is where the silicon powder is finally discharged from the feeder.

[0029] A guide cylinder 5 with the same horizontal axis is fixedly connected inside the feeding cylinder 202. The left and right side walls of the feeding cylinder 202 have configuration holes 205 penetrating the inner and outer walls. The guide cylinder 5 is fixedly connected within the configuration holes 205. A distributing roller 6 is also rotatably connected inside the guide cylinder 5. A fan-shaped feed inlet 501 is opened at the top of the guide cylinder 5, with a larger upper end and a smaller lower end. A discharge outlet 502 is opened at the bottom of the guide cylinder 5. Although the discharge outlet 502 is also fan-shaped in this embodiment, it does not necessarily have to be fan-shaped for distributing materials. The outer side of the roller 6 is provided with a fan-shaped partition groove 602. There are several partition grooves 602. These partition grooves 602 are arranged at equal intervals around the rotation axis of the distributing roller 6. Each partition groove 602 can be connected to the feed port 501 or the discharge port 502. The partition groove 602 is also completely blocked by the inner wall of the guide tube 5. Therefore, each partition groove 602 cannot be connected to the feed port 501 and the discharge port 502 at the same time. In other words, the distributing roller 6, together with the guide tube 5, can separate the materials in the storage bin 201 and the funnel 206.

[0030] The end of the distributing roller 6 has an end shaft 601, which can pass through the guide tube 5 and connect to the output end of the reduction motor 3. The upper surface of the support plate 101 has a vertical bracket 103. In fact, there is a pair of brackets 103 on the upper surface of the support plate 101. The machine body 2 is located between the two brackets 103. The two brackets 103 respectively block the two ends of the guide tube 5. The reduction motor 3 is fixedly connected to the outer side of the bracket 103. The bracket 103 has a horizontal shaft hole 104 for the end shaft 601 to pass through to form a rotating pair. The horizontal shaft hole 104 is usually also equipped with a bearing structure. In order to reduce the friction of the rotational engagement, both ends of the distributing roller 6 actually have an end shaft 601, which is used to cooperate with the two brackets 103 respectively to form a rotating pair, thereby ensuring the stability of the rotation of the distributing roller 6.

[0031] The top of the feeding cylinder 202 has a storage bin 201 with a larger internal volume, capable of storing more silicon powder. A cover 7 is installed on the top of the storage bin 201 to prevent debris from falling into it. A stirring mechanism 4 is installed on the side wall of the storage bin 201 to agitate the silicon powder material inside. The stirring mechanism 4 includes a motor 401 and a reducer 402 fixedly connected to the outer side of the storage bin 201. The output end of the motor 401 is connected to the input end of the reducer 402, and a drive shaft 403 is fixedly connected to the output end of the reducer 402. In practice, two reducers 402 are installed, with their output ends connected to... There is one drive shaft 403, and the two drive shafts 403 rotate in opposite directions. The part of the drive shaft 403 extending into the storage bin 201 has a stirring rod 404. The relatively rotating stirring rods 404 can simultaneously press the silicon powder material downward to fill the partition groove 602. The side wall of the storage bin 201 has a longitudinal shaft hole 203 for the drive shaft 403 to pass through and form a rotating pair. Similarly, a bearing structure is also installed in the longitudinal shaft hole 203 to reduce rotational friction. The inner wall of the other opposite side wall of the storage bin 201 is fixedly connected to a bushing 204, which is used to cooperate with the end of the drive shaft 403 to form a rotating pair, constrain the end of the drive shaft 403, and ensure the stable operation of the drive shaft 403.

[0032] Working principle: During use, silicon powder is added to the storage silo 201 and the cover 7 is closed. Then, the stirring mechanism 4 is activated, causing the stirring rod 404 to apply downward pressure to the silicon powder, filling the partition groove 602 aligned with the inner wall of the inlet 501. The motor used in the reduction motor 3 is a servo motor, which drives the distributing roller 6 to rotate in one direction. When the partition groove 602, filled with silicon powder, is completely blocked by the guide cylinder 5, the amount of silicon powder entering the partition groove 602 reaches the standard amount and is determined. 6. Continue rotating. When the partition trough 602 filled with silicon powder overlaps with the discharge port 502, the silicon powder in the partition trough 602 will be discharged from the funnel 206 under its own gravity. At the same time, the other partition trough 602, which does not contain silicon powder, gradually overlaps with the feed port 501 and will also be quickly filled with silicon powder. By repeating the above cycle, efficient and quantitative silicon powder feeding can be achieved. After the partition trough 602 is completely blocked by the guide tube 5, the smaller the internal volume, the finer the material distribution, and the higher the precision control of feeding can be.

Those skilled in the art should understand that this application is not limited to the above embodiments.
