Description

Technical Field

[0001] The invention relates to the field of material transportation, in particular to a feeder and a material conveying device. Background Art

[0002] During the conveying process, powder materials will accumulate in the barrel below the discharge port to form an accumulation angle. If the accumulation angle is not removed, the space in the barrel will be wasted, and the barrel required for a single transport will increase. If the accumulation angle is to be removed, manual cooperation is required, which affects efficiency. Especially for the material accumulation angle in the barrel below the degasser, since a spiral is set in the vertical feed pipe of the degasser, when removing the material accumulation angle, it is necessary to first turn off the spiral in the degasser to prevent accidents, which greatly affects efficiency. Therefore, it is necessary to propose a feeder that can automatically remove the material accumulation angle. Summary of the invention

[0003] In order to solve the technical problem in the prior art that the material accumulation angle generated by the feeder during the feeding process needs to be manually removed, which is time-consuming and labor-intensive and affects the efficiency, the present invention provides a feeder that solves the above technical problem.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] The present invention provides a feeder, comprising a main shaft and a feeding member driven by the main shaft, characterized in that a material-discharging impeller is arranged at one end of the main shaft close to the discharge point, and the material-discharging impeller is assembled to the main shaft by means of a soft connection component, and the soft connection component comprises a first linkage component located at the end of the main shaft and a second linkage component rigidly connected to the material-discharging impeller, the first linkage component and the second linkage component are assembled for relative rotation, and when the material-discharging impeller moves toward the main shaft under the action of an external force, it drives the second linkage component to press toward the first linkage component, and when the first linkage component and the second linkage component are pressed together, the power of the main shaft is transmitted to the material-discharging impeller.

[0006] Furthermore, the first linkage member is a conical end formed at the end of the main shaft, and the second linkage member is a conical sleeve formed on the material-discharging impeller. The conical sleeve is rotatably assembled on the conical end and a gap is formed between the two in the axial direction of the main shaft.

[0007] Furthermore, a limiting portion protruding radially along the end surface is formed on the conical end, and the conical sleeve is sleeved on the conical end and limited by the limiting portion.

[0008] Furthermore, the limiting portion is integrally formed with the conical end or is detachably connected to the end of the conical end.

[0009] Furthermore, the conical sleeve is formed with a limiting groove for accommodating the limiting portion.

[0010] Furthermore, the blades of the material-discharging impeller extend along the radial direction of the conical sleeve and are obliquely connected to the outer circumference of the conical sleeve at an angle to the horizontal direction.

[0011] Further, the blades extend away from the conical sleeve along the radial direction of the conical sleeve and bend toward the downstream of the rotation direction of the material-discharging impeller.

[0012] Another aspect of the present invention provides a material conveying device, comprising: the feeder and a barrel as described above, wherein the barrel is used to receive the material of the feeder, and the material-discharging impeller of the feeder penetrates into the barrel.

[0013] Based on the above structure, the technical effects that can be achieved by the present invention are:

[0014] 1. The feeder of the present invention comprises a feeding tube and a main shaft arranged in the feeding tube, a material-discharging impeller is arranged near the discharge position of the main shaft, and the material-discharging impeller is softly connected to the main shaft. When the accumulation angle of materials in the barrel is accumulated to the material-discharging impeller, the material-discharging impeller will be lifted by the materials on the accumulation angle so that the second linkage member on the material-discharging impeller is pressed with the first linkage member at the end of the main shaft, and the pressed material-discharging impeller rotates with the main shaft, and the blades of the rotating material-discharging impeller will discharge the materials on the accumulation angle to the tip of the blades of the material-discharging impeller. At this time, the materials discharged to the tip of the blades fall into the unfilled area near the inner wall of the barrel in the barrel, thereby realizing the automatic removal of the material accumulation angle, smoothing the materials in the barrel, and making full use of the space in the barrel.

[0015] 2. In the initial state of the feeder of the feeding device of the present invention, when the material at the stacking angle has not yet been stacked at the conical sleeve, there is a gap between the conical sleeve and the conical surface of the conical end, and the main shaft does not transmit power to the conical sleeve, that is, the material-discharging impeller does not rotate. When the material at the stacking angle is stacked at the conical sleeve, the conical sleeve is lifted and moves upward under the action of the material, so that the conical sleeve is pressed against the conical end, and the conical surfaces of the two are in close contact to form a linkage. At this time, the main shaft transmits power to the conical sleeve through the conical surfaces in close contact with the two, so that the material-discharging impeller rotates, and when the material-discharging impeller discharges the material at this moment, the material-discharging impeller will move downward under the action of gravity. After the downward movement, the material-discharging impeller is separated from the linkage state with the main shaft, and rotates slowly under the action of inertia to discharge the material, so as to prevent the material-discharging impeller from forming an "electric fan" to blow out the material in the barrel. It should be noted that the material-dispensing impeller and the main shaft are always in this state of press fit - separation - press fit - separation during the whole material-dispensing process, so that the speed of the material-dispensing impeller is always lower than the speed of the main shaft (the main shaft is provided with a spiral for conveying materials, so the speed cannot be too slow), thereby avoiding the situation where the material is blown out of the barrel due to the material-dispensing impeller speed being too fast. Furthermore, when the barrel is about to be filled, the main shaft drive motor is turned off and the main shaft stops rotating. At this time, there is no more material output in the feeding pipe, and the material-dispensing impeller continues to rotate and dispense materials under the action of inertia. As the material in the barrel is completely smoothed, the resistance force of the smoothed material in the barrel to the rotation of the material-dispensing impeller gradually becomes greater than the rotational force of the material-dispensing impeller under the action of inertia, and the material-dispensing impeller automatically stops moving. The soft connection between the material-discharging impeller and the main shaft controls the rotation speed of the material-discharging impeller to prevent the material from being blown out of the barrel. At the same time, such a soft connection relationship also enables the same drive motor to output two different rotation speeds, so that the material-discharging impeller does not need to be separately equipped with a drive motor and a corresponding drive mechanism, which reduces costs and saves energy.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0024] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0025] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0026] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0027] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0028] During the conveying process, powder materials will accumulate in the barrel below the discharge port to form an accumulation angle. If the accumulation angle is not removed, the space in the barrel will be wasted, increasing the barrel required for a single transport. If the accumulation angle is to be removed, manual cooperation is required, which affects efficiency. In particular, for the material accumulation angle in the barrel below the degasser, since a spiral is provided in the vertical feed pipe of the degasser, when removing the material accumulation angle, it is necessary to first turn off the spiral in the degasser to prevent accidents, which greatly affects efficiency. In view of this, this embodiment proposes a feeder that uses a material-dispensing impeller to remove the material accumulation angle.

[0029] Example 1

[0030] like Figure 1-3As shown, this embodiment provides a feeder, including a main shaft 1 and a feeding member 2 driven by the main shaft 1. The feeding member 2 in this example is a vertically arranged feeding tube and a main shaft 1 rotatably disposed in the feeding tube. A material-discharging impeller 3 is arranged at one end of the main shaft 1 close to the discharge point. The material-discharging impeller 3 is assembled to the main shaft 1 with the aid of a soft connection component. The soft connection component includes a first linkage member located at the end of the main shaft 1 and a second linkage member rigidly connected to the material-discharging impeller 3. The first linkage member and the second linkage member are assembled for relative rotation. When the material-discharging impeller 3 moves toward the main shaft 1 under the action of an external force, it drives the second linkage member to press against the first linkage member. When the first linkage member and the second linkage member are pressed together, the power of the main shaft 1 is transmitted to the material-discharging impeller 3 to rotate the material-discharging impeller 3.

[0031] The feeder in this embodiment includes a feeding tube and a main shaft 1 arranged in the feeding tube. A material-discharging impeller 3 is arranged on the main shaft 1 near the discharge point. The material-discharging impeller 3 is softly connected to the main shaft 1. When the accumulation angle of materials in the barrel 4 is accumulated to the material-discharging impeller 3, the material-discharging impeller 3 will be lifted by the materials on the accumulation angle so that the second linkage member on the material-discharging impeller 3 is pressed with the first linkage member at the end of the main shaft 1. The pressed material-discharging impeller 3 rotates with the main shaft 1. The blades 31 of the rotating material-discharging impeller 3 will discharge the materials on the accumulation angle to the tip of the blades 31 of the material-discharging impeller 3. At this time, the materials discharged to the tip of the blades fall into the unfilled area of ​​the barrel 4 near the inner wall of the barrel 4, thereby realizing the automatic removal of the material accumulation angle, smoothing the materials in the barrel 4, and making full use of the space in the barrel 4.

[0032] In the preferred scheme of this embodiment, the first linkage member is a conical end 11 formed at the end of the main shaft 1, and the second linkage member is a conical sleeve 32 formed on the material-discharging impeller 3. The conical sleeve 32 is rotatably assembled on the conical end 11 and a gap is formed between the two in the axial direction of the main shaft 1. In the initial state of feeding, when the material at the stacking angle has not yet been stacked at the conical sleeve 32, there is a gap between the conical surfaces of the conical sleeve 32 and the conical end 11, and the main shaft 1 does not transmit power to the conical sleeve 32, that is, the material-discharging impeller 3 does not rotate. When the material at the stacking angle is stacked at the conical sleeve 32, the conical sleeve 32 is lifted up and moves upward under the action of the material, so that the conical sleeve 32 is pressed against the conical end 11, and the conical surfaces of the two are in close contact to form a linkage. At this time, the main shaft 1 transmits power to the conical sleeve 32 through the conical surfaces in close contact with the two, so that the material-discharging impeller 3 rotates. When the material-discharging impeller 3 discharges the material at this moment, the material-discharging impeller 3 will move downward under the action of gravity. After the downward movement, the material-discharging impeller 3 is separated from the linkage state with the main shaft 1, and rotates slowly under the action of inertia to prevent the material-discharging impeller 3 from forming an "electric fan" to blow out the material in the barrel 4. It should be noted that the material-dispensing impeller 3 and the main shaft 1 are always in this state of press fit-separation-press fit-separation during the whole material-dispensing process, so that the speed of the material-dispensing impeller 3 is always lower than the speed of the main shaft 1 (the main shaft 1 is provided with a spiral for conveying materials, so the speed cannot be too slow), thereby avoiding the situation where the material is blown out of the barrel 4 due to the too fast speed of the material-dispensing impeller 3. Furthermore, when the barrel 4 is about to be filled, the driving motor of the main shaft 1 is turned off and the main shaft 1 stops rotating. At this time, there is no more material output in the feeding pipe, and the material-dispensing impeller 3 continues to rotate and dispense materials under the action of inertia. As the material in the barrel 4 is completely smoothed, the resistance force of the smoothed material in the barrel 4 to the rotation of the material-dispensing impeller 3 gradually becomes greater than the rotational force of the material-dispensing impeller 3 under the action of inertia, and the material-dispensing impeller 3 automatically stops moving. The soft connection between the material-discharging impeller 3 and the main shaft 1 controls the rotation speed of the material-discharging impeller 3 to prevent the material from being blown out of the barrel 4. At the same time, such a soft connection relationship also enables the same drive motor to output two different rotation speeds, so that the material-discharging impeller 3 does not need to be separately configured with a drive motor and a corresponding drive mechanism, thereby reducing costs and saving energy.

[0033] In order to prevent the tapered sleeve 32 from escaping from the conical end 11 of the main shaft 1, a limiting portion 12 protruding radially along the end surface is formed on the conical end 11. In this embodiment, the limiting portion 12 is configured as a circular protrusion, which limits the tapered sleeve 32 sleeved on the conical end 11 to prevent the tapered sleeve 32 from escaping from the main shaft 1. When the materials at the stacking angle are not stacked to the tapered sleeve 32, the tapered sleeve 32 falls to the lowest point of the main shaft 1 under the action of gravity. The tapered sleeve 32 that falls to the lowest point of the main shaft 1 forms a gap with the conical end 11 in the axial direction of the main shaft 1, and the tapered sleeve 32 is limited by the limiting portion 12 and will not fall off from the conical end 11 of the main shaft 1.

[0034] The limiting part 12 in this example is integrally formed with the conical end 11 or detachably connected to the end of the conical end 11, and the detachable connection method can be bolted. The material-dispensing impeller 3 of the feeder in this example needs to match the barrel 4. In the best state, the maximum diameter of the material-dispensing impeller 3 is slightly smaller than the inner diameter of the receiving port of the barrel 4. The setting of the detachably connected limiting part 12 can make the feeder in this example more convenient to match the barrels 4 of different specifications to realize automatic stacking angle removal.

[0035] In a preferred solution of this embodiment, the conical sleeve 32 is formed with a limiting groove 33 for accommodating the limiting portion 12 .

[0036] In order to enable the material-moving impeller 3 to move more materials at the stacking angle, the blades 31 of the material-moving impeller 3 extend along the radial direction of the tapered sleeve 32 and are obliquely connected to the outer circumference of the tapered sleeve 32 at an angle to the horizontal direction. The inclined surface of the blades 31 obliquely connected to the outer circumference of the tapered sleeve 32 can be formed as a material-moving part when moving materials.

[0037] In order to better move the material, the blade 31 extends away from the cone sleeve 32 along the radial direction of the cone sleeve 32 and bends toward the downstream of the rotation direction of the material moving impeller 3. When moving the material, the material on the stacking angle is first driven by the connecting part of the blade 31 close to the cone sleeve 32, and then the material moves along the extension direction of the blade 31 to the tip of the blade 31 away from the cone sleeve 32 and finally falls into the area of ​​the barrel 4 close to the inner wall of the barrel 4. When the blade 31 bends toward the downstream of the rotation direction of the material moving impeller 3, the material moving along the extension direction of the blade 31 will also be buffered. When the buffered material reaches the tip of the blade 31, it will fall into the barrel 4 under the action of gravity instead of flying out radially along the main shaft 1, reducing the risk of the material being thrown out of the barrel 4 by the material moving impeller 3. That is, when the feeder of this embodiment removes the stacking angle, it is actually a process in which the material moving on the stacking angle is slowly moved to the periphery by the material moving impeller 3, rather than throwing the material out forcefully.

[0038] like Figure 4 As shown, another aspect of this embodiment further provides a feeding device, including the above-mentioned feeder and a barrel 4, the barrel 4 is used to receive the material of the feeder, and the feeder's material-dispensing impeller 3 penetrates into the barrel 4. In a preferred embodiment, the material-dispensing impeller 3 that penetrates into the barrel 4 is arranged near the receiving port of the barrel 4.

[0039] Based on the above basic structure, the feeding impeller 3 of the feeder of the feeding device of the present embodiment goes deep into the barrel 4. When the material in the barrel 4 is not accumulated, the conical sleeve 32 of the feeding impeller 3 falls to the lowest point of the main shaft 1 under the action of gravity. The conical sleeve 32 that falls to the lowest point of the main shaft 1 forms a gap with the conical end 11 in the axial direction of the main shaft 1. The main shaft 1 does not transmit power to the feeding impeller 3, and the feeding impeller 3 does not rotate. When the material begins to accumulate at the feeding impeller 3, the conical sleeve 32 is lifted by the material and pressed onto the conical end 11 of the main shaft 1. At this time, the main shaft 1 is in close contact with the conical surface of the two. The power is transmitted to the tapered sleeve 32, and the material-discharging impeller 3 rotates to start discharging the material. During the material-discharging process, the material-discharging impeller 3 and the main shaft 1 are in a state of press fit - separation - press fit - separation, that is, the material-discharging impeller 3 is rotated under the inertia force. When the barrel 4 is about to be filled, the main shaft 1 stops rotating, the feeder also stops feeding, and the material-discharging impeller 3 continues feeding under the action of inertia until the blades 31 of the material-discharging impeller 3 from the connection part close to the tapered sleeve 32 to the blade tip are blocked by the material in the barrel 4 and stop rotating, completing the entire process of removing the accumulation angle and smoothing the material.

[0040] Embodiment 2

[0041] The difference between the second embodiment and the first embodiment is that: Figure 5 As shown, the first linkage is a first rough contact surface 13 formed on one end surface of the main shaft 1 near the discharge point, and the second linkage is a second rough contact surface 34 formed on the material-discharging impeller 3 and facing the first rough contact surface 13. At the same time, a thin shaft 14 is provided on the end surface where the first rough contact surface 13 of the main shaft 1 is located, and the material-discharging impeller 3 is rotatably mounted on the thin shaft 14, and a gap is formed between the second rough contact surface 34 and the first rough contact surface 13 in the axial direction of the main shaft 1. The other parts in the second embodiment are the same as those in the first embodiment, and are not repeated here.

[0042] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
