Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for spinning equipment, and specifically to a granule feeding device. Background Technology

[0002] When using granular materials, a feeding mechanism is required. In existing technologies, this mechanism typically employs a spiral pusher structure, utilizing the rotation of spiral blades to guide the material along a spiral channel formed by the blades. However, this type of feeding mechanism is prone to rubbing and adhering to each other during the process of particles being guided along the spiral channel, leading to blockages and hindering particle feeding. Furthermore, the spiral pusher structure lacks anti-blocking properties, and cannot completely stop feeding when the material is no longer needed, resulting in poor controllability. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pellet feeding device with controllable feeding and less clogging.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A pellet feeding device, comprising:

[0006] A hopper assembly having a storage chamber for storing materials and a material channel for the materials to flow out of the hopper assembly;

[0007] A feeding assembly is disposed on the hopper assembly and divides the storage chamber into an upper cavity and a lower cavity that are isolated from each other. The feeding assembly is located above the material channel and has a feeding channel for material flow. The feeding assembly has a feeding state and a non-feeding state. When the feeding assembly is in the feeding state, the feeding channel is unobstructed. When the feeding assembly is in the non-feeding state, the feeding channel is blocked.

[0008] The air supply mechanism includes a base fixedly connected to the hopper assembly. The base is provided with an air inlet channel for compressed gas to enter the base and an outlet channel for material and compressed gas to flow out of the base together. The outlet channel is connected to the material channel, and there is a gap between the inlet of the outlet channel and the outlet of the material channel. The air intake of the air inlet channel creates a negative pressure in the gap area.

[0009] In some embodiments, the feeding assembly includes a first feeding plate disposed on the hopper assembly, a second feeding plate disposed below the first feeding plate, and a distribution plate disposed between the first feeding plate and the second feeding plate. The distribution plate is rotatably disposed. The upper cavity is formed above the first feeding plate, and the lower cavity is formed below the second feeding plate. When the distribution plate rotates, the feeding channel is unobstructed. When the distribution plate does not rotate, the feeding channel is blocked.

[0010] In some embodiments, the first feeding plate is provided with a first feeding port penetrating its upper and lower end faces, the second feeding plate is provided with a second feeding port penetrating its upper and lower end faces, and the distributing plate is provided with a distributing port penetrating its upper and lower end faces. The first feeding port, the distributing port, and the second feeding port form the feeding channel. The position of the first feeding port and the position of the second feeding port are offset. The distributing plate can be rotated to make the position of the distributing port correspond to the position of the first feeding port or the second feeding port.

[0011] In some embodiments, at least one first discharge port and one second discharge port are provided along the circumferential direction of rotation of the distribution disc, and multiple distribution ports are provided.

[0012] In some embodiments, the first feeding plate has a tapered structure with a larger upper end and a smaller lower end facing the upper cavity, and the first feeding port is located near the smaller end of the tapered structure.

[0013] In some embodiments, the feeding device further includes a guide member disposed in the lower cavity. The guide member includes a disc body located at the upper part and a first column body disposed at the lower part of the disc body. The disc body has a conical structure that is larger at the top and smaller at the bottom. The first column body is sequentially connected to the small end of the disc body, and the material channel is formed on the first column body.

[0014] In some embodiments, the housing is further provided with an air intake chamber communicating with the air intake channel, and the feeding device further includes a cyclone separator disposed in the air intake chamber, the inlet of the cyclone separator communicating with the air intake chamber, and the outlet of the cyclone separator communicating with the lower cavity.

[0015] In some embodiments, the feeding device further includes a connector, a second column is provided in the base, the discharge channel is at least partially formed on the second column, the upper part of the connector is fixedly connected to the first column, the lower part of the connector is fixedly connected to the second column, and the connector is provided with a hollow area that allows the negative pressure airflow in the lower cavity to enter the interval area.

[0016] In some embodiments, the discharge channel includes a central channel disposed at the center of the seat and a side channel having one end connected to the central channel, the central channel being located directly below the material channel.

[0017] In some embodiments, the feeding device further includes a hopper, which has a conical structure that is larger at the top and smaller at the bottom. The hopper is connected to the hopper assembly via a pipe, and a control valve is provided on the pipe to control the opening or closing of the pipe. The feeding device also includes a sensor provided on the hopper assembly for monitoring the material height in the upper cavity.

[0018] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: When the feeding component is in the non-feeding state, the feeding channel of the pellet feeding device of this utility model is blocked, and feeding cannot be achieved. Only when the feeding component is in the feeding state can the feeding channel be unobstructed, thus enabling feeding. This allows the feeding of the device to be controlled as needed, resulting in better controllability. Furthermore, during the feeding process, by supplying air to the air inlet channel, a negative pressure airflow can be formed between the inlet of the discharge channel and the outlet of the material channel. This allows the material in the material channel to flow into the discharge channel under the action of the negative pressure airflow and move along the discharge channel. This avoids blockage of the material channel and discharge channel, thus preventing material supply from being affected and improving feeding efficiency. Attached Figure Description

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component 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. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] like Figures 1-6 As shown, the pellet feeding device of this utility model includes a hopper assembly, a feeding assembly, and an air supply mechanism.

[0029] The hopper assembly has a storage chamber for storing materials. In this embodiment, the hopper assembly includes an upper hopper 11 located at the top and a lower hopper 12 located at the bottom. The lower hopper 12 is provided with a material channel 321 for the material to flow out of the hopper assembly.

[0030] The feeding assembly is disposed on the hopper assembly and divides the storage chamber into an upper cavity 111 and a lower cavity 121 that are isolated from each other. In this embodiment, the feeding assembly is disposed between the upper hopper 11 and the lower hopper 12, the upper cavity 111 is formed on the upper hopper 11, and the lower cavity 121 is formed on the lower hopper 12.

[0031] The feeding assembly is located above the material channel 321, and has a feeding channel for material flow. The feeding assembly has a feeding state and a non-feeding state. When the feeding assembly is in the feeding state, the feeding channel is unobstructed, and material flows from the upper cavity 111 into the lower cavity 121 through the feeding channel, and then flows out of the hopper assembly through the material channel 321. When the feeding assembly is in the non-feeding state, the feeding channel is blocked, and the material is stored in the upper cavity 111.

[0032] like Figure 4 and Figure 6 As shown, in this embodiment, the feeding assembly includes a first feeding plate 21, a second feeding plate 22, and a distributing disc 23. The second feeding plate 22 is disposed below the first feeding plate 21, and the distributing disc 23 is disposed between the first feeding plate 21 and the second feeding plate 22, and is rotatably disposed relative to the first feeding plate 21 and the second feeding plate 22. In this embodiment, the second feeding plate 22 is provided with a groove that is concave downward from its upper end, and the distributing disc 23 is rotatably disposed within this groove. The upper cavity 111 is formed above the first feeding plate 21, and the lower cavity 121 is formed below the second feeding plate 22. When the distributing disc 23 rotates, the feeding channel is unobstructed; when the distributing disc 23 does not rotate, the feeding channel is blocked.

[0033] Specifically, such as Figure 2 , Figure 4 and Figure 6 As shown, the first feeding plate 21 is provided with a first feeding port 211 that penetrates its upper and lower end faces, the second feeding plate 22 is provided with a second feeding port 221 that penetrates its upper and lower end faces, and the distributing plate 23 is provided with a distributing port 231 that penetrates its upper and lower end faces. The first feeding port 211, the distributing port 231, and the second feeding port 221 are arranged sequentially from top to bottom to form a feeding channel. The position of the first feeding port 211 is staggered from the position of the second feeding port 221. The size of the first feeding port 211 and the second feeding port 221 is larger than the size of the distributing port 231. The distributing plate 23 can be rotated so that the position of the distributing port 231 corresponds to the position of the first feeding port 211 or the second feeding port 221.

[0034] When the feeding assembly is in the feeding state, the distributing disc 23 first rotates until the distributing port 231 corresponds to the position of the first feeding port 211. The material in the upper cavity 111 then flows from the first feeding port 211 into the distributing port 231. At this time, the position of the distributing port 231 is offset from the position of the second feeding port 221. When the distributing disc 23 continues to rotate until the position of the distributing port 231 corresponds to the position of the second feeding port 221, the material in the distributing port 231 flows into the lower cavity 121 through the second feeding port 221.

[0035] When the feeding component is in a non-feeding state, the feeding disc 23 does not rotate. The feeding disc 23 can only correspond to the position of one of the first feeding port 211 and the second feeding port 221 at most. In this way, the feeding channel is always blocked and feeding cannot be achieved.

[0036] This feeding method of the feeding component ensures that materials do not flow out of the feeding channel at all when feeding is not required, thus providing good control over the feeding process.

[0037] Along the circumferential direction of rotation of the distribution disc 23, at least one first discharge port 211 and one second discharge port 221 are provided, and multiple distribution ports 231 are provided. In this embodiment, two first discharge ports 211 and two second discharge ports 221 are provided, and multiple distribution ports 231 are evenly distributed along the circumferential direction of rotation of the distribution disc 23. This arrangement allows for continuous feeding when one distribution port 231 corresponds to the position of the first discharge port 211, and when that distribution port 231 rotates to correspond to the position of the second discharge port 221, allowing feeding from the first discharge port 211 to the distribution port 231, another distribution port 231 can rotate again to correspond to the position of the first discharge port 211, allowing feeding from the first discharge port 211 to the distribution port 231. This cycle ensures continuous feeding and improves feeding efficiency.

[0038] The feeding assembly also includes a drive mechanism 24, which drives the dispensing disk 23 to rotate. In this embodiment, the drive mechanism 24 has a rotatable output shaft 241, and the dispensing disk 23 is fixedly connected to the output shaft 241. When the drive mechanism 24 is activated, causing the output shaft 241 to rotate, it drives the dispensing disk 23 to rotate synchronously. In this embodiment, the drive mechanism 24 includes a drive motor.

[0039] By controlling the speed of the drive motor, the amount of material fed can be controlled.

[0040] The first feeding plate 21 has a tapered structure at one end facing the upper cavity 111, which is wider at the top and narrower at the bottom. The first feeding port 211 is located near the narrow end of the tapered structure. This makes it easier for the material in the upper cavity 111 to fall into the first feeding port 211 under its own gravity, guided by the tapered structure.

[0041] The feeding device also includes a guide member 3 disposed in the lower cavity 121. The guide member 3 is located below the feeding assembly, and a material channel 321 is formed on the guide member 3. The guide member 3 is used to guide the material falling into the lower cavity 121, so that the material flows out of the hopper assembly from the material channel 321.

[0042] Specifically, such as Figure 2 , Figure 4 and Figure 6As shown, the guide component 3 includes a disc 31 located at the upper part and a first column 32 disposed at the lower part of the disc 31. The disc 31 has a conical structure that is larger at the top and smaller at the bottom. The first column 32 is sequentially connected to the small end of the disc 31, and a material channel 321 is formed on the first column 32. In this embodiment, the material channel 321 is the central hole of the first column 32.

[0043] After the material falls from the second discharge port 221, it falls onto the disc 31. The conical structure of the disc 31 can play a good guiding role, making it easier for the material to fall into the material channel 321 under its own gravity.

[0044] The gas supply mechanism is used to supply compressed gas into the hopper assembly to create a negative pressure at the outlet of the material channel 321. This negative pressure allows the material to flow better in the material channel 321 and the discharge channel, preventing blockage of the material channel 321 and the discharge channel, which would otherwise affect the normal feeding of the feeding device.

[0045] The air supply mechanism includes a base 4, which is fixedly connected to the hopper assembly. In this embodiment, the base 4 is fixedly connected to the lower part of the hopper 12. Figure 4 As shown, the base 4 is provided with an air inlet channel 41 for compressed gas to enter the base and an outlet channel for material and compressed gas to flow out of the base 4 together. The outlet channel is connected to the material channel 321. The gas supply mechanism also includes a gas source device (not shown in the figure), which is connected to the air inlet channel 41 through a pipeline to input compressed gas into the air inlet channel 41.

[0046] There is a gap between the inlet of the discharge channel and the outlet of the material channel 321. Compressed gas entering from the air inlet channel 41 can flow into the gap between the inlet of the discharge channel and the outlet of the material channel 321, thereby forming a negative pressure.

[0047] The discharge channel includes a central channel 421 located at the center of the base 4 and a side channel 422 connected to the central channel 421 at one end. The central channel 421 is located directly below the material channel 321. The size of the central channel 421 is not smaller than the size of the material channel 321. Preferably, the central axis of the central channel 421 and the material channel 321 are collinear, so that the material flowing out of the material channel 321 enters the central channel 421 as much as possible under the action of negative pressure.

[0048] In this embodiment, a second column 42 is provided at the center of the base 4, and the central channel 421 is the central hole of the second column 42.

[0049] The guide component 3 is fixedly installed inside the lower cavity 121 via the connector 5. For example... Figure 2 , Figure 4 and Figure 6As shown, the connector 5 includes a first connecting part 51 located at the upper part and a second connecting part 52 located at the lower part. The first connecting part 51 is sleeved on the outside of the first column 32 and fixed to the first column 32, and the second connecting part 52 is sleeved on the outside of the second column 42 and fixed to the second column 42.

[0050] like Figure 4 As shown, the base 4 also has an air intake chamber 43 connected to the air intake channel 41, and the lower part of the hopper 12 is completely open. The feeding device also includes a cyclone separator 6 installed in the air intake chamber 43. The inlet of the cyclone separator 6 is connected to the air intake chamber 43, and the outlet of the cyclone separator 6 is connected to the lower cavity 121. The cyclone separator 6 can adopt the structure of the prior art, and its specific structure will not be described in detail. Compressed gas flows into the air intake chamber 43 through the air intake channel 41 and enters the cyclone separator 6. After flowing out of the cyclone separator 6, it forms a spiral airflow and enters the lower cavity 121.

[0051] In this embodiment, such as Figure 4 As shown, the lower part of the second connecting part 52 is pressed onto the cyclone separator 6, thereby pressing the cyclone separator 6 between the second connecting part 52 and the base 4, thus fixing the cyclone separator 6.

[0052] like Figure 2 , Figure 4 and Figure 6 As shown, there is a hollow area between the first connecting part 51 and the second connecting part 52, so that the airflow in the lower cavity 121 can flow from the hollow area to the gap area between the inlet of the discharge channel and the outlet of the material channel 321.

[0053] In this embodiment, to simplify the structure of the entire feeding device, no sealing design is made between the hopper assembly, the guide 3 and the lower hopper 12. In this way, the airflow entering the lower cavity 121 will spiral up along the side wall of the hopper assembly until it fills the upper cavity 111 and the lower cavity 121 above the disc 31, and forms positive pressure in these areas. Thus, when the compressed gas enters the lower cavity 121 again through the cyclone separator 6, the compressed gas flows from the hollow area between the first connecting part 51 and the second connecting part 52 to the gap area between the inlet of the discharge channel and the outlet of the material channel 321, thereby forming negative pressure.

[0054] like Figure 1 , Figures 3-6 As shown, the feeding device also includes a hopper 7, which has a cone-shaped structure that is larger at the top and smaller at the bottom. The hopper 7 is connected to the hopper assembly through a pipe, and a control valve 8 is installed on the pipe to control the opening or closing of the pipe.

[0055] The feeding device also includes a sensor 9, which is installed on the hopper assembly and has its sensing end extending into the upper cavity 111. The sensor 9 is used to monitor the material height in the upper cavity 111.

[0056] When the material level in the upper cavity 111 is lower than the set height, the control valve 8 opens the pipeline, allowing material to be fed into the upper cavity 111 through the hopper 7. When the material level in the upper cavity 111 is not lower than the set height, the control valve 8 closes the pipeline, preventing material from flowing into the upper cavity 111 from the hopper 7.

[0057] The feeding device also includes a controller. The drive mechanism 24, the air source device, and the control valve 8 are all electrically connected to the controller to control the operation of each component. The sensor 9 is electrically connected to the controller to send detection signals to the controller.

[0058] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
