Description

Technical Field

[0001] This invention relates to the field of material conveying, and more particularly to an online unblocking device for a vibrating feeder and a vibrating feeder. Background Technology

[0002] In thermal power plants, steel mills, and chemical plants, it is common to unload, store, receive, and transport bulk materials such as coal, coke, ore, and limestone. Currently, many projects in the industry are equipped with vibrating feeders, such as double-arc curve vibrating feeders, for bulk material feeding. In recent years, due to stricter environmental requirements, increased costs of energy-saving and emission-reduction materials, and other environmental factors, raw materials have become unstable. For example, the ash content of materials may continuously increase, especially after rain / snow in the mining area or during transportation, leading to increased moisture content. During operation, the double-arc curve vibrating feeder experiences continuous material adhesion on the inner side of the arc-shaped discharge plate. Furthermore, under the excitation force of its vibrating motor, the adhered material hardens severely, resulting in a decrease in feeding output. In severe cases, this can cause blockage of the entire equipment, leading to the breakage of the entire material conveying system and affecting the normal operation of the plant.

[0003] The current solution to the problem of material sticking and clogging on the inner side of the arc-shaped discharge plate of the vibrating feeder is manual cleaning. However, manual cleaning requires the vibrating feeder to be stopped, and there are a series of safety and material supply instability issues, which seriously restrict the overall safety and economic operation of the factory. Summary of the Invention

[0004] The technical problem solved by the embodiments of the present invention is that when material sticks and clogs the inner side of the arc-shaped discharge plate of the vibrating feeder, manual cleaning poses safety and material supply instability issues.

[0005] To address the aforementioned technical problems, this invention provides an online unblocking device for a vibrating feeder. The online unblocking device is used to clean the material adhering to the discharge plate of the vibrating feeder. The online unblocking device includes: a scraping and cleaning assembly, a drive mechanism, a support mechanism, and a limiting member. The drive mechanism includes a drive device and a drive shaft; the drive device drives the drive shaft to rotate. The scraping and cleaning assembly is connected to the drive shaft and reciprocates along the axial direction of the drive shaft under the drive of the drive device. The scraping and cleaning assembly is located above the discharge plate. The support mechanism connects the drive mechanism to the bracket of the vibrating feeder. The limiting member is fixed to the support mechanism and restricts the movement of the scraping and cleaning assembly around the circumference of the drive shaft.

[0006] Optionally, the scraping cleaning assembly includes a scraper with a toothed structure on the edge facing the discharge plate, the toothed structure including a plurality of teeth.

[0007] Optionally, adjacent teeth may have different inclination directions.

[0008] Optionally, adjacent teeth may be tilted in opposite directions.

[0009] Optionally, the scraping and cleaning assembly further includes a cleaning plate, the edge of which is detachably connected to the scraper.

[0010] Optionally, the cleaning plate has mounting holes on its edge for connecting the scraper.

[0011] Optionally, the mounting hole is a slotted hole.

[0012] Optionally, the scraping and cleaning assembly further includes a push nut, which is connected to the cleaning plate and is sleeved on the outside of the drive shaft.

[0013] Optionally, the end face of the push nut is provided with a plurality of first openings.

[0014] Optionally, the scraping cleaning assembly has a slot for passing through the limiting member.

[0015] Optionally, the online unblocking device further includes rollers or balls, which are disposed in the slot and contact the limiting member.

[0016] Optionally, the cleaning plate is provided with a first clearance opening, which is used to pass through the limiting member.

[0017] Optionally, the extending direction of the limiting member is parallel to the extending direction of the drive shaft.

[0018] Optionally, the limiting member has an arc-shaped surface, or the surface of the limiting member is provided with reinforcing ribs, the extending direction of the reinforcing ribs being parallel to the extending direction of the limiting member.

[0019] Optionally, the support mechanism includes a support portion, a bearing housing, and a bearing, wherein: the support portion is used to install the drive device, the limiting member, and the bracket for connecting the vibrating feeder; the bearing housing is fixedly connected to the support portion and is used to support the bearing; the bearing is connected to the drive shaft.

[0020] This invention also provides a vibrating feeder, including any of the above-mentioned online unblocking devices.

[0021] Compared with the prior art, the technical solution of the embodiments of the present invention has the following beneficial effects:

[0022] This invention provides an online unblocking device for a vibrating feeder, which can be used to clean the adhesive material adhering to the discharge plate of the vibrating feeder. Specifically, the online unblocking device may include a scraping and cleaning component, a drive mechanism, a support mechanism, and a limiting component. The limiting component is fixed to the support mechanism to restrict the movement of the scraping and cleaning component around the circumferential direction of the drive shaft. The drive device drives the drive shaft to rotate. The scraping and cleaning component can reciprocate along the axial direction of the drive shaft under the drive of the drive device. The scraping and cleaning component is located above the discharge plate, so that when the vibrating feeder vibrates and discharges material, the scraping and cleaning component collides with the adhesive material on the discharge plate. Under the combined strong action of the horizontal and vertical amplitude vibration of the vibrating feeder and the axial displacement of the scraping and cleaning component, the adhesive material is detached from the flow surface of the vibrating feeder and flows away with the material flow, thus cleaning the adhesive material from the discharge plate (i.e., the flow surface of the vibrating feeder). As the cleaning component reciprocates along the axial direction of the drive shaft, the adhesive material on the discharge plate can be continuously cleaned. This invention enables automatic cleaning of material adhering to the discharge plate without stopping the vibrating feeder during operation. Compared to existing methods that require stopping the vibrating feeder and manual cleaning, the online unblocking device provided in this embodiment improves the safety and efficiency of unblocking, and ensures the stability and reliability of material supply.

[0023] Furthermore, the different inclination directions of adjacent teeth on the scraper can improve the unclogging effect on sticky materials.

[0024] Furthermore, the scraper is detachably connected to the cleaning plate, making it easy to replace the scraper when it is damaged but the cleaning plate is intact, thus saving costs.

[0025] Furthermore, multiple first openings are provided on the end face of the push nut to effectively prevent jamming between the drive shaft and the push nut.

[0026] Furthermore, the limiting member has an arc-shaped surface, or the surface of the limiting member is provided with reinforcing ribs, the extending direction of which is parallel to the extending direction of the limiting member. This improves the strength of the limiting member and enhances its vibration resistance. Attached Figure Description

Detailed Implementation

[0042] As mentioned above, due to stricter environmental protection requirements, increased costs of energy-saving and emission-reduction materials, and other environmental factors, raw materials become unstable. Materials, due to their own stickiness or freezing at low temperatures and prolonged inactivity, can caking and adhere to the flow surface, causing a decrease in the feed rate of the vibrating feeder and affecting its normal operation. For example, if the ash content of the material continues to rise, especially after rain / snow in the mining area or during transportation, the moisture content of the material increases. During operation of the double-arc vibrating feeder, material continuously sticks to the inner side of the arc-shaped discharge plate, and under the excitation force of its vibrating motor, the stuck material hardens severely. In other words, when the material (such as coal) has a high ash, moisture, and impurity content, coal will stick, and the material will become increasingly compacted, causing caking. Furthermore, when the temperature is below zero degrees Celsius, the caking material can freeze.

[0043] The current solution to the problem of material sticking and clogging on the inner side of the arc-shaped discharge plate of the vibrating feeder is manual cleaning. However, manual cleaning requires the vibrating feeder to be stopped, and there are a series of safety and material supply instability issues, which seriously restrict the overall safety and economic operation of the factory.

[0044] To address the aforementioned problems, this invention provides an online unblocking device for a vibrating feeder, which can be used to clean the adhesive material adhering to the discharge plate of the vibrating feeder. Specifically, the online unblocking device may include a scraping and cleaning component, a drive mechanism, a support mechanism, and a limiting component. The limiting component is fixed to the support mechanism to restrict the movement of the scraping and cleaning component around the circumferential direction of the drive shaft. The drive device drives the drive shaft to rotate. The scraping and cleaning component can reciprocate along the axial direction of the drive shaft under the drive of the drive device. The scraping and cleaning component is located above the discharge plate, so that when the vibrating feeder vibrates and discharges material, the scraping and cleaning component collides with the adhesive material on the discharge plate. Under the combined strong force of the horizontal and vertical amplitude vibration of the vibrating feeder and the axial displacement of the scraping and cleaning component, the adhesive material is detached from the flow surface of the vibrating feeder and flows away with the material flow, thus cleaning the adhesive material from the discharge plate (i.e., the flow surface of the vibrating feeder). As the scraping and cleaning component reciprocates along the axial direction of the drive shaft, the adhesive material on the discharge plate can be continuously cleaned. This invention enables automatic cleaning of material adhering to the discharge plate without stopping the vibrating feeder during operation. Compared to existing methods that require stopping the vibrating feeder and using manual cleaning, the online unblocking device provided in this embodiment improves the safety and efficiency of unblocking, and ensures the stability and reliability of material supply.

[0045] To make the above-mentioned objectives, features and beneficial effects of the embodiments of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0046] This invention provides an online unblocking device for a vibrating feeder, which is used to clean the sticky material adhering to the discharge plate of the vibrating feeder. The sticky material refers to the material adhering to the discharge plate.

[0047] Reference Figure 1 A structural schematic diagram of a vibrating feeder according to an embodiment of the present invention is provided; Figure 2 This is a partial structural schematic diagram of a vibrating feeder according to an embodiment of the present invention; Figure 3 This is a schematic diagram of the structure of an online unblocking device according to an embodiment of the present invention; Figure 4 yes Figure 3 A magnified view of a section at point A in the middle; Figure 5 yes Figure 3 A magnified view of a section at point B in the middle; Figure 6 yes Figure 3 A magnified view of a section at point C; Figure 7 yes Figure 3 Exploded view; Figure 8 This is an exploded view of the scraping and cleaning component in an embodiment of the present invention. The following is in conjunction with... Figures 1 to 8 The specific structure of the online blockage clearing equipment is explained.

[0048] In a specific implementation, the vibrating feeder 1 may include a discharge plate 10, an online unblocking device 20, a housing 30, a support 40, an excitation spring 50, a vibration isolation spring 60, and an excitation motor. The housing 30 is connected to the support 40 via the vibration isolation spring 60. The excitation spring 50 can deform under the action of the excitation motor to drive the housing 30 to vibrate, thereby driving the discharge plate 10 installed inside the housing 30 to vibrate in the vertical and / or vertical direction. The discharge plate 10 serves as the flow surface of the vibrating feeder 1. Under the action of the vertical and / or vertical vibration of the discharge plate 10, the material flows out from the discharge port to achieve discharge.

[0049] In some non-limiting embodiments, the vibrating feeder 1 may also be provided with an activation block 70. The activation block 70 is disposed below the feed inlet of the vibrating feeder 1 to slow down and disperse the material, and to prevent the material from accumulating at the discharge outlet in an instant, thus affecting the discharge.

[0050] The online blockage clearing device 20 may include: a scraping and cleaning component 21, a drive mechanism 22, a support mechanism 23, and a limiting component 24.

[0051] The drive mechanism 22 may include a drive device 221 and a drive shaft 222. The drive device 221 is used to drive the drive shaft 222 to rotate.

[0052] The scraping and cleaning assembly 21 is connected to the drive shaft 222, and the scraping and cleaning assembly 21 moves axially along the drive shaft 222 under the drive of the drive device 221. The scraping and cleaning assembly 21 is located above the discharge plate 10.

[0053] In a specific implementation, the rotation direction of the drive shaft can be adjusted by the drive device 221, thereby adjusting the rotation direction of the scraping and cleaning component 21 along the drive shaft 22, so that the scraping and cleaning component 21 reciprocates along the drive shaft 222, thereby cleaning the material adhering to each area on the discharge plate 10.

[0054] The support mechanism 23 is used to connect the drive mechanism 22 to the bracket 40 of the vibrating feeder 1.

[0055] The limiting member 24 is fixed to the support mechanism 23 and is used to restrict the circumferential movement of the scraping and cleaning assembly 21 around the drive shaft 222. By limiting the circumferential movement of the scraping and cleaning assembly 21 around the drive shaft 222 by the limiting member 24, it is possible to prevent the scraping and cleaning assembly 21 from colliding with other components on the vibrating feeder 1 during operation. These other components can be the activation block 70 of the vibrating feeder, or the discharge plate 10, etc. In addition, the limiting member 24 can also shield the drive shaft 222, reducing dust falling on the drive shaft 222 and ensuring the smooth axial movement of the scraping and cleaning assembly 21 along the drive shaft 222.

[0056] In practice, the limiting member 24 can restrict the movement of the scraping and cleaning assembly 21 around the circumference of the drive shaft in a variety of ways.

[0057] For example, combining Figure 8 The scraping and cleaning assembly 21 has a slot 2123. The slot 2123 is used to pass through the limiting member 24. That is, the limiting member 24 is located in the slot 2123. Since the two ends of the limiting member 24 are fixedly connected to the support mechanism 23, when the drive shaft 222 rotates, the scraping and cleaning assembly 21 is restricted by the limiting member 24 and cannot move around the circumference of the drive shaft 222, thus realizing the linear movement of the scraping and cleaning assembly 21 along the drive shaft 222.

[0058] in, Figure 8 The illustration uses one slot 2123 as an example. In this case, there is one slot 2123 and one limiting member 24. The slot 2123 is located above the drive shaft 222 to improve the limiting effect of the limiting member 24 on the scraping cleaning component 21 along the circumferential direction of the drive shaft 222.

[0059] It is understandable that the number of limiting members 24 can also be two or more, in which case the number of slots 2123 is the same as the number of limiting members 24. The slots 2123 can be spaced apart at the edge of the cleaning plate 212. The edges of the slots 2123 on the cleaning plate 212 are located away from the scraper 211.

[0060] When there are two slots 2123, the two slots 2123 can be symmetrically arranged on the cleaning plate 212 relative to the drive shaft 222.

[0061] For example, refer to Figure 9 A schematic diagram of the cleaning plate in another scraping and cleaning assembly according to an embodiment of the present invention is provided. The cleaning plate 212 is provided with a first clearance opening 2126. The first clearance opening 2126 is used to pass through the limiting member 24.

[0062] It should be noted that, Figure 9 The shape of the first clearance opening 2126 shown is merely a non-limiting example and does not limit the scope of protection of the present invention. In practice, the shape of the first clearance opening 2126 can be adapted to the outer surface contour of the limiting member 24. For example, if the outer surface contour of the limiting member 24 is circular, then the shape of the first clearance opening 2126 is circular. As another example, if the outer surface contour of the limiting member 24 is elliptical, then the shape of the first clearance opening 2126 is elliptical. Yet another example, if the outer surface contour of the limiting member 24 is semi-circular, then the shape of the first clearance opening 2126 is semi-circular. Still another example, if the outer surface contour of the limiting member 24 is triangular, then the shape of the first clearance opening 2126 is triangular. It is understood that the shape of the first clearance opening 2126 can also be other shapes, which will not be listed here.

[0063] The number of first clearance openings 2126 can be one or more. The number of first clearance openings 2126 is related to the setting position of the first clearance openings 2126 on the cleaning plate 212.

[0064] To balance the strength of the cleaning plate 212 and the limiting effect of the limiting member 24 on the cleaning plate 212 along the circumferential direction of the drive shaft 222, the number of first clearance openings 2126 is two. The two first clearance openings 2126 are symmetrically arranged relative to the drive shaft 222.

[0065] In some embodiments, the limiting member 24 may include an arc-shaped surface 241, so that the central region of the limiting member 24 has high strength, thereby improving the overall strength of the limiting member 24 and giving the limiting member 24 high vibration resistance.

[0066] In other embodiments, the limiting member 24 may be provided with reinforcing ribs. The extending direction of the reinforcing ribs is parallel to the extending direction of the limiting member 24. The provided reinforcing ribs can improve the overall strength of the limiting member 24, giving the limiting member 24 higher vibration resistance.

[0067] For some vibrating feeders 1 equipped with activation blocks 70, the online unblocking device 20 can be set below the activation blocks 70 to prevent the material entering the feed inlet from directly hitting the online unblocking device 20.

[0068] As shown above, the online unblocking equipment can be used to clean the adhesive material adhering to the discharge plate of a vibrating feeder. Specifically, the online unblocking equipment can include a scraping and cleaning component, a drive mechanism, a support mechanism, and a limiting component. The limiting component is fixed to the support mechanism and is used to restrict the movement of the scraping and cleaning component around the circumferential direction of the drive shaft. The drive device drives the drive shaft to rotate. The scraping and cleaning component can reciprocate along the axial direction of the drive shaft under the drive of the drive device. The scraping and cleaning component is located above the discharge plate, so that when the vibrating feeder vibrates and discharges material, the scraping and cleaning component collides with the adhesive material on the discharge plate. Under the combined strong action of the horizontal and vertical amplitude vibration of the vibrating feeder and the axial displacement of the scraping and cleaning component, the adhesive material is detached from the flow surface of the vibrating feeder and flows away with the material flow, thus cleaning the adhesive material from the discharge plate. As the scraping and cleaning component reciprocates along the axial direction of the drive shaft, the adhesive material on the discharge plate can be continuously cleaned. This allows for automatic cleaning of the adhesive material on the discharge plate without stopping the vibrating feeder during operation. Compared to existing methods that require stopping the vibrating feeder and using manual cleaning, the online unblocking equipment provided in this invention can improve the safety and efficiency of unblocking, as well as ensure the stability and reliability of material supply.

[0069] Furthermore, the online unblocking device 20 provided in this embodiment of the invention is easy to install. It is applicable to various types of existing vibrating feeders. It only requires opening the housing 30 of the vibrating feeder to allow the limit member and drive shaft to pass through. Then, the drive mechanism 22 is mounted on the bracket 40 through the support mechanism 23. The workload of modifying the vibrating feeder is relatively small.

[0070] Furthermore, the online blockage clearing device 20 has a simple structure, strong stability, and is easy to maintain.

[0071] In some embodiments, the drive device 221 may be a lead screw motor, a servo motor, or other device capable of driving the drive shaft 222 to rotate.

[0072] In some embodiments, the drive device 221 may include a reducer in addition to various suitable motors such as a lead screw motor or a servo motor. The reducer is disposed between the lead screw motor or the servo motor and the drive shaft 222 to reduce the output speed of the lead screw motor or the servo motor, so that the drive shaft 222 can rotate at a suitable speed.

[0073] In specific implementation, the scraping and cleaning assembly 21 includes a scraper 211. The scraper 211 has a toothed structure on its edge facing the discharge plate 10, and the toothed structure includes multiple teeth 2111. When the vibrating feeder 1 is working, the vibration of the excitation spring 50 on the vibrating feeder 1 can drive the discharge plate 10 to vibrate, thereby causing the sticky material on the discharge plate 10 to collide with the scraper 211. With the help of the scraping and cleaning assembly 21, it moves axially along the drive shaft 222. During the axial movement of the scraping and cleaning assembly 21 along the drive shaft 222, as the sticky material on the discharge plate 10 collides with the toothed structure of the scraper 211, under the combined strong force of the vibrating feeder 1 and the axial displacement of the scraping and cleaning assembly 21, the multiple teeth 2111 in the toothed structure can scrape the sticky material off the discharge plate 10. The scraped-off sticky material flows away with the material flow, thereby achieving the cleaning of the sticky material on the discharge plate 10. The toothed structure can improve the cleaning effect of sticky material.

[0074] In some embodiments, the tilting directions of the plurality of teeth 2111 may be the same, or the plurality of teeth 2111 may include at least a first tooth and a second tooth with different tilting directions.

[0075] In some embodiments, adjacent teeth 2111 have different inclination directions to improve the unclogging effect on adhesive material.

[0076] Furthermore, the inclination directions of adjacent teeth 2111 are opposite.

[0077] In practice, the edge contour of the toothed structure of the scraper 211 is adapted to the contour of the discharge plate 10 to improve the cleaning effect on the material adhering to the discharge plate 10.

[0078] In some embodiments, there is a gap between the edge contour of the toothed structure of the scraper 211 and the discharge plate 10. The size of the gap is related to the amplitude of the vibrating feeder 1 in the vertical direction and is not less than the amplitude of the vibrating feeder 1 in the vertical direction.

[0079] In a specific implementation, the scraping and cleaning assembly 21 also includes a cleaning plate 212. The scraper 211 is detachably connected to the edge of the cleaning plate 212. Since the scraper 211 is prone to wear during use, and the scraper 211 is detachably connected to the cleaning plate 212, when the scraper 211 needs to be replaced, only the scraper 211 needs to be replaced. If the cleaning plate 212 is intact, it does not need to be replaced, thereby saving costs.

[0080] In a specific implementation, a second clearance opening 2124 is provided on the cleaning plate 212. The second clearance opening 2124 is used for the drive shaft 222 to pass through.

[0081] In some non-limiting embodiments, combined with Figure 6 and Figure 8 The cleaning plate 212 has multiple mounting holes 2121 on its edge. The scraper 211 has multiple mating holes 2112. The mating holes 2112 correspond to the mounting holes 2121. The scraper 211 is fixed to the cleaning plate 212 by using fasteners such as screws, bolts, and rivets.

[0082] In some embodiments, the mounting hole 2121 can be a round hole, a square hole, or other suitable holes.

[0083] In some embodiments, the mounting hole 2121 is an oblong hole. Thus, by adjusting the mounting position of the scraper 211 within the oblong hole, the relative distance between the scraper 211 and the discharge plate 10 can be adjusted to adapt to different types of vibrating feeders 1, thereby achieving the versatility of the online unblocking device 20 for vibrating feeders.

[0084] When the discharge plate 10 is a double-arc curve feed plate, and the discharge port of the vibrating feeder 1 is located in the middle of the double-arc curve feed plate, the scraper 211 can be symmetrically arranged on the cleaning plate 212.

[0085] In some embodiments, the cleaning plate 212 may be provided with a recess 2125. The position of the recess 2125 corresponds to the position of the discharge port of the vibrating feeder 1. In this way, the impact on the discharge port during the unblocking process of the online unblocking device 20 is minimized.

[0086] There are two scrapers 211, which are symmetrically arranged on both sides of the concave portion 2125.

[0087] It should be noted that in practice, due to the different shapes of the discharge plate 10 of different models of vibrating feeders 1, the setting position and shape of the scraper 211 on the cleaning plate 212 are different. The specific settings are made according to the actual application requirements, and will not be listed here.

[0088] In a specific implementation, the scraping and cleaning assembly 21 further includes a push nut 25. The push nut 25 is connected to the cleaning plate 212 and is sleeved on the outside of the drive shaft 222.

[0089] The cleaning plate 212 is provided with a second clearance opening 2124. The push nut 25 is connected to the cleaning plate 212 through the second clearance opening 2124.

[0090] The push nut 25 and the cleaning plate 212 can be connected by snap-fit, threaded connection, or fastener mating hole.

[0091] In some embodiments, the push nut 25 and the drive shaft 222 can be connected by threads. For example, the push nut 25 and the drive shaft 222 can be connected by a trapezoidal nut. This allows the push nut 25 to move along the central axis of the drive shaft 222 when the drive shaft 222 rotates, thereby driving the scraping cleaning assembly 21 to move along the central axis of the drive shaft 222.

[0092] Furthermore, combined with Figure 5 and Figure 8 The end face of the push nut 25 is provided with a plurality of first openings 251. This can effectively prevent the drive shaft 222 and the push nut 25 from jamming.

[0093] Furthermore, the cleaning plate 212 is provided with a plurality of second openings 2122. The positions of the plurality of second openings 2122 correspond to the positions of the first openings 251.

[0095] In some non-limiting embodiments, combined with Figure 10 and Figure 13 The vibrating feeder 1 may also include rollers 26 or balls, which are disposed in the slots 2123 and contact the limiting member 24. When the scraping and cleaning assembly 21 moves along the drive shaft 222, the friction between the scraping and cleaning assembly 21 and the limiting member 24 can be reduced by the rollers 26 or balls.

[0096] In some non-limiting embodiments, a mounting groove 2123a is provided within the card slot 2123. A roller 26 is disposed within the mounting groove 2123a. Specifically, the roller 26 includes a rolling portion 261 and a rotating shaft 262.

[0097] The direction of the central axis of roller 26 is perpendicular to the direction of the central axis of drive shaft 222.

[0098] In some implementations, the rotating shaft 262 is disposed at both ends of the rolling part 261. A shaft hole is provided in the mounting groove 2123a, and the rotating shaft 262 is located in the shaft hole. The limiting member 24 contacts the rolling part 261, and when the scraping and cleaning assembly 21 moves axially along the drive shaft 222, the rolling part 261 drives the rotating shaft 262 to rotate in the shaft hole.

[0099] In other embodiments, the rolling part 261 is sleeved on the rotating shaft 262 and can rotate around the rotating shaft 262 under the action of friction between it and the limiting part 24.

[0100] In some embodiments, the rolling part 261 is cylindrical.

[0109] The drive unit 221 is fixed to 40 using a dedicated third support 2313 in conjunction with the connecting part 2314, which improves the ease of installation of the drive unit 221. It is understood that in some modified embodiments, the drive unit 221 may also be fixed to one of the second support parts 2312.

[0110] It should be noted that in some modified embodiments, the support part can also be a one-piece molded component, and the drive device 221, the limiting member 24, and the bearing seat 232 are all installed on the support part.

[0111] Both ends of the drive shaft 222 are connected to the bearing 233 respectively, and are connected to the support part through the corresponding bearing housing 232.

[0112] In some embodiments, the online unblocking device 20 may further include a seal (not shown) fitted onto the outside of the drive shaft 222. The seal is used to seal an opening in the housing of the vibrating feeder through which the drive shaft 222 passes. Since dust is usually generated during the operation of the vibrating feeder, the seal prevents dust from escaping from the housing of the vibrating feeder 1.

[0113] The seal can be a sealing rubber ring, or a shielding part or other component that can seal an opening.

[0114] Combination Figures 1 to 13 This invention also provides a vibrating feeder 1, which may include the online unblocking device 20 provided in any of the above embodiments. The specific structures of the vibrating feeder 1 and the online unblocking device 20 can be referred to the descriptions in any of the above embodiments, and will not be repeated here.

[0115] In practical implementation, the vibrating feeder can be a dual-mass activation feeder, a double-arc curve vibrating feeder, or other vibrating feeders that achieve feeding through vibration. The accompanying drawings provided in this embodiment illustrate the structure of a double-arc curve vibrating feeder as an example. When the vibrating feeder is of other types, its structure will change accordingly. These will not be illustrated individually here.

[0116] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
