Description

Technical Field

[0001] This utility model relates to the field of feeding, and in particular to a feeding device. Background Technology

[0002] Traditional feeding devices transport powder from a cylinder to a designated location for weighing or further processing. A typical feeding device includes a cylinder and a material conveying mechanism located at the bottom of the cylinder.

[0003] Regarding the connection between the material cylinder and the material conveying mechanism, a cylindrical guide pipe is installed at the bottom of the material cylinder. This guide pipe connects directly to the outer wall of the conveying cylinder of the material conveying mechanism, allowing powder to be guided from the material cylinder through the guide pipe into the conveying cylinder, and then transported by the conveying mechanism to one end of the conveying cylinder. One end of the guide pipe connects to the material cylinder, and the other end connects to the conveying cylinder. The cylindrical structure of the guide pipe causes the powder to fall vertically downwards at a high speed, making it prone to accumulation. This can even lead to excessive and uneven powder accumulation in certain areas of the conveying screw, resulting in uneven powder delivery and affecting the discharge speed. Furthermore, excessive powder accumulation in certain areas of the conveying screw can cause blockages, or uneven force distribution that prevents rotation, and may even clog the guide pipe.

[0004] In addition, due to gravity, powder often accumulates at the discharge port of the conveyor cylinder, gradually forming lumps that are difficult to process later. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a feeding device that controls the material dropping speed and prevents blockage.

[0006] To solve the above-mentioned technical problems, this utility model provides a feeding device, including a material storage container and a material conveying mechanism. The material storage container includes a guiding part, and the material conveying mechanism includes a conveying body. The conveying body is located at the bottom end of the guiding part, and the bottom end of the guiding part is provided with a discharge port. The guiding part is connected to the conveying body through the discharge port.

[0007] The cross-sectional area of ​​the material guiding section gradually decreases from the top to the bottom.

[0008] The connection between the material guide and the conveying body is provided with a first connecting edge and a second connecting edge, which together form the material discharge port; the length of the first connecting edge is greater than the length of the second connecting edge.

[0009] As an improvement to the above solution, the material conveying mechanism further includes a conveying component disposed within the conveying body, the conveying component being used to convey powder from one end of the conveying body to the other end;

[0010] The extension direction of the first connecting edge is the same as the conveying direction of the conveying component.

[0011] As an improvement to the above solution, the longitudinal section of the guiding part is an inverted equilateral trapezoid, and the shape of the conveying body is a cylinder;

[0012] The conveying direction of the conveying component is the same as the axial direction of the conveying body;

[0013] The axes of the guide section and the conveyor body are perpendicular to each other.

[0014] As an improvement to the above solution, the extension direction of the second connecting edge is the same as the radial direction of the conveying body, and the length of the second connecting edge is less than the diameter of the conveying body.

[0015] As an improvement to the above solution, the inclination angle of the side wall where the material guide is connected to the first connecting edge is smaller than the inclination angle of the side wall where the material guide is connected to the second connecting edge.

[0016] As an improvement to the above solution, the feeding device includes a mounting frame, which includes a base and several support columns. The material storage container is located above the base, and the support columns are connected to the material storage container and the base respectively.

[0017] As an improvement to the above solution, the material storage container further includes a discharge section located at the top of the material guiding section, and the discharge section is fixedly connected to the support column;

[0018] The support columns are spaced apart circumferentially along the unloading section.

[0019] As an improvement to the above solution, the shape of the feeding part is a cylinder, and the included angles formed by the lines connecting two adjacent support columns and the center of the feeding part are equal.

[0020] As an improvement to the above solution, the base includes a horizontal bar and a vertical bar, with one end of the vertical bar being perpendicularly connected to the horizontal bar;

[0021] The number of support columns is at least three, and the support columns are respectively located at both ends of the horizontal bar and the other end of the vertical bar.

[0022] As an improvement to the above solution, one end of the conveying body is provided with a discharge port, and a limiting component is provided at the discharge port;

[0023] The limiting component includes a connecting block and several limiting strips. The connecting block is connected to the conveying body through the limiting strips to divide the discharge port into several small discharge ports.

[0024] Implementing this utility model has the following beneficial effects:

[0025] This utility model feeding device includes a material storage container and a material conveying mechanism. The conveying body of the material conveying mechanism is located at the bottom end of the guiding section of the material storage container. The guiding section is connected to the conveying body through a discharge port, allowing the powder in the material storage container to fall into the conveying body through the discharge port and then be conveyed out by the conveying components within the conveying body. The cross-sectional area of ​​the guiding section gradually decreases from the top to the bottom, guiding and slowing down the falling powder. Compared with existing structures, this reduces the falling speed, preventing blockages caused by excessively fast falling, and effectively controlling the falling speed. The length of the first connecting side is greater than the length of the second connecting side, distributing the position of the powder falling into the conveying body and preventing powder from concentrating at a certain position. This controls the falling speed, prevents blockages, and ensures uniform falling, thus guaranteeing uniform output from the material conveying mechanism. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0032] See Figure 1-5 This utility model discloses a feeding device, including a material storage container 1 and a material conveying mechanism. The material storage container 1 includes a guiding part 11, and the material conveying mechanism includes a conveying body 2. The conveying body 2 is located at the bottom end of the guiding part 11, and the bottom end of the guiding part 11 is provided with a discharge port (not shown in the figure). The guiding part 11 is connected to the conveying body 2 through the discharge port.

[0033] The cross-sectional area of ​​the material guiding section 11 gradually decreases from the top to the bottom.

[0034] The connection between the material guiding part 11 and the conveying body 2 is provided with a first connecting edge 112 and a second connecting edge 113, which together form the material discharge port; the length a of the first connecting edge 112 is greater than the length b of the second connecting edge 113.

[0035] This utility model feeding device includes a material storage container and a material conveying mechanism. The conveying body of the material conveying mechanism is located at the bottom end of the guiding section of the material storage container. The guiding section is connected to the conveying body through a discharge port, allowing the powder in the material storage container to fall into the conveying body through the discharge port and then be conveyed out by the conveying components within the conveying body. The cross-sectional area of ​​the guiding section gradually decreases from the top to the bottom, guiding and slowing down the falling powder. Compared with existing structures, this reduces the falling speed, preventing blockages caused by excessively fast falling, and effectively controlling the falling speed. The length of the first connecting side is greater than the length of the second connecting side, distributing the position of the powder falling into the conveying body and preventing powder from concentrating at a certain position. This controls the falling speed, prevents blockages, and ensures uniform falling, thus guaranteeing uniform output from the material conveying mechanism.

[0036] Preferably, the material conveying mechanism is a screw conveyor. Existing technology can be used for screw conveyors, and they will not be described in detail here.

[0037] It should be noted that there are at least two first connecting edges 111, which are arranged parallel to each other; there are at least two second connecting edges 112, which are symmetrically arranged at both ends of the first connecting edges 111 to form a material discharge port. Therefore, the projected shape of the material discharge port is rectangular.

[0038] Specifically, the material conveying mechanism also includes a conveying component (not shown in the figure) disposed within the conveying body 2. The conveying component is used to convey powder from one end of the conveying body 2 to the other end. The conveying component is a conveying screw, with a motor disposed at one end of the conveying body and the conveying screw disposed within the conveying body. The motor drives the conveying screw to rotate, so that the powder on the conveying screw is conveyed to the discharge port 21 at the other end of the conveying body.

[0039] The first connecting edge 111 extends in the same direction as the conveying component, ensuring that the powder falling from the first connecting edge onto the conveying component is evenly distributed on the component. This prevents powder from accumulating at a certain location on the conveying component, causing blockages, affecting the rotation of the conveying component, or even causing uneven discharge. The extension direction of the first connecting edge is its length direction.

[0040] Preferably, the longitudinal section of the guide section 11 is an inverted equilateral trapezoid, and the conveying body 2 is cylindrical. More preferably, the base of the inverted equilateral trapezoid and the axis of the conveying body 2 are parallel to each other. The conveying direction of the conveying component is the same as the axial direction of the conveying body 2.

[0041] It should be noted that the material storage container 1 has a symmetrical three-dimensional shape, and its axis of symmetry is the axis of the material guiding part. Moreover, the axis of the material guiding part 11 lies on the longitudinal section of the material guiding part. Therefore, the longitudinal section of the material guiding part 11 and the axis of the conveying body 2 are on the same plane. Thus, the connection structure between the material storage container and the conveying body is also a symmetrical connection structure, further ensuring the reliability and stability of the connection between the two.

[0042] More preferably, the axes of the guide section 11 and the conveying body 2 are perpendicular to each other, ensuring that the material conveying mechanism is located in the middle of the material storage container, so that the material conveying mechanism is balanced as a whole, and the connection between the material storage container and the material conveying mechanism is more stable and reliable.

[0043] More preferably, the extension direction of the second connecting edge 112 is the same as the radial direction of the conveying body, and the length of the second connecting edge 112 is less than the diameter of the conveying body 2, so that the length of the second connecting edge is approximately equal to the diameter of the conveying component, thereby ensuring that the powder falling into the conveying body from the discharge port is basically placed into the conveying component, improving the utilization rate and conveying rate of the powder.

[0044] Specifically, the inclination angle of the sidewall connecting the material guide section 11 to the first connecting edge 111 is smaller than the inclination angle of the sidewall connecting the material guide section 11 to the second connecting edge 112. Here, "inclination angle" refers to the angle between the sidewall of the material guide section and a plane perpendicular to the axis of the material guide section. Therefore, the sidewall connected to the first connecting edge is relatively gentle, resulting in a slower speed at which the powder falls into the discharge port; the sidewall connected to the second connecting edge is steeper, resulting in a faster speed at which the powder falls into the discharge port. This difference in the movement speed of the powder within the material guide section effectively controls the discharge speed and prevents powder blockage.

[0045] Furthermore, such as Figure 1 , 4 As shown in Figure 5, the feeding device includes a mounting frame 5, which comprises a base 51 and several support columns 52. The material storage container 1 is positioned above the base 51, and the support columns 52 are connected to both the material storage container 1 and the base 51. This invention, through the support of the support columns, suspends the material storage container and the material conveying mechanism in mid-air, facilitating the installation of powder receiving and conveying devices. Furthermore, the multiple support columns provide more space around the material storage container and the material conveying mechanism for installation, simplifying the process. Moreover, it has fewer components, a smaller size, a simpler structure, and lower cost.

[0046] Preferably, such as Figure 1 , 4 As shown, the material storage container 1 also includes a discharge section 12 located at the top of the material guiding section 11, and the discharge section 12 is fixedly connected to the support columns 52; the support columns 52 are spaced apart circumferentially along the discharge section 12. Powder enters the material guiding section through the discharge section. The discharge section is formed by extending upwards from the top of the material guiding section. The support columns are located around the discharge section, providing effective support for the material storage container.

[0047] More preferably, the feeding section 12 is cylindrical in shape, and the included angles formed by the lines connecting two adjacent support columns 52 and the center of the feeding section 12 are equal. That is, the support columns are evenly distributed around the material storage container to ensure force balance and reliable support, thereby ensuring the reliability and stability of the overall connection structure.

[0048] Preferably, such as Figure 5 As shown, the base 51 includes a horizontal bar 511 and a vertical bar 512, with one end of the vertical bar 512 vertically connected to the horizontal bar 511. The base has a simple structure, low cost, and avoids occupying the space below the material conveying mechanism, facilitating the installation of other equipment.

[0049] More preferably, there are at least three support columns 52, which are respectively located at both ends of the horizontal bar 511 and the other end of the vertical bar 512. The distribution of the three support columns forms a triangular distribution structure, further ensuring more reliable and stable support for the material storage container.

[0050] Furthermore, such as Figure 3 As shown, one end of the conveying body 2 is provided with a discharge port 21, and a limiting member 4 is provided at the discharge port 21. The limiting member 4 includes a connecting block 41 and several limiting strips 42. The connecting block 41 is connected to the conveying body 2 through the limiting strips 42 to divide the discharge port 21 into several small discharge ports 211. The limiting strips are spaced apart and arranged circumferentially along the discharge port. The small discharge ports 211 are formed between two adjacent limiting strips 42 and the conveying body 2. Under the combined action of the connecting block and the limiting strips, the powder pushed towards the discharge port will leak out from multiple small discharge ports, avoiding the formation of lumpy powder.

[0051] In summary, this utility model provides a feeding device with a reasonable and reliable structure that is easy to install.

[0052] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
