Description

Technical Field

[0001] The present invention relates to the technical field of feeding devices, and more specifically, to a feeding device for aluminum nitride powder. Background Art

[0002] The feeding device for aluminum nitride powder is a key device designed for the precise transportation of aluminum nitride powder to a designated position or process equipment, and it plays an indispensable role in the production, processing, and application processes of aluminum nitride powder. According to the differences in actual application scenarios and process requirements, various types of feeding devices can be selected. Among them, the pneumatic conveying feeding device is favored in large-scale applications due to its high efficiency and flexibility.

[0003] However, during the actual use of the pneumatic conveying feeding device, it often faces the challenge of blockage at the bent parts of the conveying pipeline. This not only causes a large amount of aluminum nitride powder to accumulate inside the device but also seriously affects production efficiency and product quality. Currently, the common solution is to manually dredge with a hard rod such as a steel bar. Although this method can alleviate the blockage problem to a certain extent, it often causes additional damage to the bent parts of the pipeline and accelerates the wear process. Due to the continuous impact and friction of aluminum nitride powder on the bent parts of the pipeline, the wear situation is particularly serious. This not only reduces the service life of the pneumatic conveying feeding device but also increases the maintenance and replacement costs, bringing unnecessary burdens to the production and operation of enterprises. In view of this, we propose a feeding device for aluminum nitride powder. Summary of the Invention

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. By designing the driving component, the connecting component and the anti-collision component, when the driving component operates, it will drive the rotating component to rotate through the connecting component and the telescopic component, so as to dredge the aluminum powder blocked at the elbow position. And the anti-collision component can be turned over to buffer the impact of the aluminum powder. On the one hand, it can avoid the aluminum powder directly hitting the elbow and causing excessive wear and damage to the inner wall of the elbow. On the other hand, the rotating component rotates inside the elbow to dredge the aluminum powder blocked in the elbow, avoiding damage to the elbow when manually dredging the elbow, ensuring the service life of the device, reducing the cost of manual replacement and dredging, and further ensuring the efficiency and safety when the device is used.

[0025] 2. The present invention also designs a rotating component and a driving component. When the pneumatic feeder transports the material into the elbow, since the motor will also operate synchronously, the spiral blade below can evenly contact the upward moving aluminum powder and reduce the speed of the aluminum powder entering the elbow through the spiral blade, avoiding direct impact of the aluminum powder on the inner wall of the elbow and causing damage to the inside of the elbow. Moreover, when blocked, the threaded blade below in the rotating state can effectively relieve the blockage problem, dredging the aluminum powder, and at the same time, the leakage troughs between several connecting blocks can reduce the impact of the device on the feeding efficiency, ensuring the service life of the elbow and the feeding efficiency.

[0026] 3. The present invention also designs an anti-collision component and a flat plate component. When the adjusting rod contacts the tooth block below the connecting ring through the convex block, the tooth block will be gradually pushed upward due to the extrusion by the inclined groove opened on one side. When the convex block disengages from the contact with the tooth block, the spring will squeeze the mounting plate to reset under the action of its own elastic force. When the aluminum powder impacts the anti-collision plate, the anti-collision plate will flip upward along the rotating shaft, and as the force of the aluminum powder impacting the anti-collision plate varies with the up and down swing, the torsion spring will drive the anti-collision plate to continuously deflect and reset along the angle of the rotating shaft while swinging up and down in the elbow, so that the anti-collision plate can not only effectively relieve the impact force when the aluminum powder impacts the inner wall of the elbow, but also can drive the blocked aluminum powder inside the elbow by swinging up and down, further reducing the possibility of blockage inside the device, and improving the stability and safety when the device is used.

[0046] As Figures 1 to 9 shown, a feeding device for aluminum nitride powder according to the present invention includes

[0047] The feeding mechanism 1 includes a pneumatic feeder 101, two connecting pipes 102 arranged on one side of the pneumatic feeder 101, a feeding pipe 103 connected to the two connecting pipes 102, a flange 104, an elbow 105, a discharge pipe 106 and a positioning card board 107. Among them, the feeding pipe 103 is connected to the elbow 105 through the flange 104, and the elbow 105 is connected to the discharge pipe 106. The mounting plate 2051 is located above the elbow 105; and, the dredging mechanism 2 includes a driving component 201, a connecting component 202 arranged below the driving component 201, a limiting sleeve 203 located outside the connecting component 202, a telescopic component 204 connected to the connecting component 202, the telescopic component 204 passes through the flat plate component 205 and is connected to the rotating component 207 and an anti-collision component 206. Among them, the anti-collision component 206 is clamped in the flat plate component 205. When feeding, the pneumatic feeder 101 and the driving component 201 are started, so that the aluminum powder enters the connecting pipe 102 along the pneumatic feeder 101 and then discharges from the discharge pipe 106 along the elbow 105. Since the driving component 201 will drive the rotating component 207 to rotate through the connecting component 202 and the telescopic component 204 during operation, the aluminum powder blocked at the position of the elbow 105 is dredged. At the same time, when the aluminum powder enters the elbow 105, it will first impact the rotating component 207 and then impact the anti-collision component 206, causing the anti-collision component 206 to flip so as to buffer the impact of the aluminum powder. On the one hand, it can avoid the inner wall of the elbow 105 from being excessively worn and damaged due to the direct impact of the aluminum powder. On the other hand, the rotating component 207 rotates inside the elbow 105 to dredge the aluminum powder blocked in the elbow 105, avoiding damage to the elbow 105 when manually dredging the elbow 105, ensuring the service life of the device, reducing the cost of manual replacement and dredging, and further ensuring the efficiency and safety of the device during use.

[0048] In an embodiment of the present invention, the pneumatic feeder 101 is communicated with two connecting pipes 102, and both of the two connecting pipes 102 are communicated with the feeding pipe 103. The top end of the feeding pipe 103 is communicated with the bottom end of the elbow 105. The top end of the feeding pipe 103 and the bottom end of the elbow 105 are fixedly connected by a flange 104. The other end of the elbow 105 is communicated with the discharging pipe 106. The top of the elbow 105 is fixedly connected with the bottom ends of two positioning clamping plates 107. The bottom end of the driving component 201 is threadedly connected with the top end of the connecting component 202. The bottom end of the connecting component 202 passes through the limiting sleeve 203 and is fixedly connected with the top end of the telescopic component 204. The bottom end of the telescopic component 204 is clamped in the flat plate component 205. The bottom end of the telescopic component 204 passes through the flat plate component 205 and is fixedly connected with the rotating component 207. The rotating component 207 is lapped below the flat plate component 205. The inner wall of the flat plate component 205 is clamped with the anti-collision component 206. The driving component 201 is installed on the two positioning clamping plates 107 above the elbow 105. The outer wall of the anti-collision component 206 is lapped with the inner wall of the elbow 105. The limiting sleeve 203 is clamped above the inner wall of the elbow 105. When the pneumatic feeder 101 conveys materials into the elbow 105, since the motor 2011 will also operate synchronously, the motor 2011 will drive a plurality of connecting blocks 2071 and the spiral blades 2072 to rotate through the slide rod 2043, the connecting rod 2022, the sliding sleeve 2041 and the reinforcing rod 2074. At this time, the adjusting rod 2075 above the connecting block 2071 will squeeze the inclined groove 2054 on one side of the tooth block 2053 through the convex block 2076, so that the mounting plate 2051 moves upward horizontally, so that the lower spiral blade 2072 can uniformly contact the upward moving aluminum powder and reduce the speed of the aluminum powder entering the elbow 105 through the spiral blade 2072, avoiding direct impact of the aluminum powder on the inner wall of the elbow 105 and causing damage to the inside of the elbow 105. And when it is blocked, the threaded blades below in the rotating state can effectively relieve the blockage problem and dredge the aluminum powder. At the same time, the leakage troughs 2073 between a plurality of connecting blocks 2071 can reduce the influence of the device on the feeding efficiency, ensuring the service life of the elbow 105 and the feeding efficiency.

[0049] In an embodiment of the present invention, the driving assembly 201 includes a motor 2011. A connecting head 2012 is fixedly connected to the bottom end of the motor 2011. Two brackets 2013 are fixedly connected to the outside of the motor 2011. The motor 2011 is fixedly connected to two positioning clamping plates 107 through the two brackets 2013 respectively. The motor 2011 is threadedly connected to the connecting assembly 202 through the connecting head 2012. The connecting assembly 202 includes a limiting rotating rod 2021. A connecting rod 2022 is fixedly connected to the top end of the limiting rotating rod 2021. The top end of the connecting rod 2022 is threadedly connected inside the connecting head 2012. The limiting rotating rod 2021 is rotatably connected inside a limiting sleeve 203. The top end of the limiting rotating rod 2021 passes through the limiting sleeve 203 and is fixedly connected to the top end of the telescopic assembly 204. When the adjusting rod 2075 contacts the tooth block 2053 below the connecting ring 2052 through the convex block 2076, the tooth block 2053 will be gradually pushed up due to the extrusion of the inclined groove 2054 opened on one side. Along with the rotation of the reinforcing rod 2074, when the convex block 2076 disengages from the contact with the tooth block 2053, the spring 2045 will push the mounting plate 2051 to reset under the action of its own elastic force, so that the anti-collision plate 2061 connected to the mounting plate 2051 on one side is always in a state of swinging up and down. At the same time, when the aluminum powder impacts the anti-collision plate 2061, the anti-collision plate 2061 will flip upward along the rotating shaft 2062. Along with the different forces of the aluminum powder impacting the anti-collision plate 2061 during the swinging up and down, the torsion spring 2064 will drive the anti-collision plate 2061 to continuously deflect and reset along the rotating shaft 2062 while swinging up and down in the elbow 105, so that the anti-collision plate 2061 can not only effectively relieve the impact force when the aluminum powder impacts the inner wall of the elbow 105, but also can push the blocked aluminum powder inside the elbow 105 by swinging up and down, further reducing the possibility of blockage inside the device, and improving the stability and safety of the device during use.

[0050] As another embodiment of the present invention, the telescopic assembly 204 includes a sliding sleeve 2041, a sliding rod 2043 is slidably connected inside the sliding sleeve 2041, a plurality of limiting grooves 2042 are formed inside the sliding sleeve 2041, and a limiting block 2044 is slidably connected inside each of the plurality of limiting grooves 2042. A plurality of limiting blocks 2044 are fixedly connected to the sliding rod 2043. A spring 2045 is arranged inside the sliding sleeve 2041. Two ends of the spring 2045 are respectively fixedly connected to the upper part of the inner wall of the sliding sleeve 2041 and the top end of the sliding rod 2043. The upper part of the sliding sleeve 2041 is fixedly connected to the bottom end of the limiting rotating rod 2021. The sliding rod 2043 is clamped inside the flat plate assembly 205. The bottom end of the sliding rod 2043 is fixedly connected to the rotating assembly 207. The flat plate assembly 205 includes a mounting plate 2051. A connecting ring 2052 is fixedly connected to the lower part of the mounting plate 2051. A plurality of tooth blocks 2053 are fixedly connected to the lower part of the connecting ring 2052. An inclined groove 2054 is arranged on one side of each of the plurality of tooth blocks 2053. Each of the plurality of inclined grooves 2054 is arc-shaped. Two positioning frames 2055 are fixedly connected to the upper part of the mounting plate 2051. The mounting plate 2051 is clamped to the anti-collision assembly 206 through the positioning frames 2055. The tooth blocks 2053 are lapped with the top end of the rotating assembly 207. The sliding rod 2043 is clamped inside the mounting plate 2051. When replacing or cleaning the device, only the connector 2012 needs to be disassembled, and then the mounting bracket 2078 can be pulled out after being removed from the inside of the elbow 105. At this time, the mounting bracket 2078 can be pulled to make the mounting bracket 2078 slide out together with the mounting plate 2051 and the anti-collision plate 2061. At this time, the limiting rotating rod 2021 will slide out along the limiting sleeve 203, reducing the difficulty of disassembling the device and enabling the device to be assembled quickly.

[0051] As another embodiment of the present invention, the anti-collision component 206 includes an anti-collision plate 2061 which is arranged in an arc shape. One side of the anti-collision plate 2061 is fixedly connected with a rotating shaft 2062. Two bearings 2063 are sleeved outside the rotating shaft 2062. Two torsion springs 2064 are arranged outside the rotating shaft 2062, and the two ends of the two torsion springs 2064 are respectively fixedly connected with the rotating shaft 2062 and the two bearings 2063. The anti-collision plate 2061 is lapped inside the elbow 105. Both of the two bearings 2063 are clamped inside the positioning frame 2055. The rotating component 207 includes a connecting block 2071. The number of the connecting blocks 2071 is several. The same spiral blade 2072 is fixedly connected outside the several connecting blocks 2071. A material leakage groove 2073 is arranged between the several connecting blocks 2071. The same reinforcing rod 2074 is fixedly connected to the tops of the several connecting blocks 2071. An adjusting rod 2075 is fixedly connected above the connecting block 2071. A convex block 2076 is fixedly connected to the top of the adjusting rod 2075. The bottom end of the reinforcing rod 2074 passes through the several connecting blocks 2071 and is sleeved inside the connecting sleeve 2077. Several mounting brackets 2078 are fixedly connected outside the connecting sleeve 2077. The top end of the reinforcing rod 2074 is fixedly connected with the bottom end of the sliding rod 2043. All of the several convex blocks 2076 are lapped below the connecting ring 2052. Because the anti-collision plate 2061 is provided and the anti-collision plate 2061 is lapped with the inner wall of the elbow 105, when the sliding rod 2043 rotates, the mounting plate 2051 is difficult to rotate due to the lapping of the anti-collision plate 2061 with the inner wall of the elbow 105, ensuring that when the convex block 2076 presses the tooth block 2053, the tooth block 2053 will not push the mounting plate 2051 to rotate, thus guaranteeing the stability of the device during operation;

[0052] By arranging a limiting groove 2042 inside the sliding sleeve 2041 and a limiting block 2044 outside the sliding rod 2043, when the sliding sleeve 2041 is driven by the limiting rotating rod 2021 to rotate, the sliding rod 2043 can rotate stably, ensuring that the motor 2011 can drive the reinforcing rod 2074 and the spiral blade 2072 to rotate stably.

[0053] Working principle: This embodiment provides a feeding device for aluminum nitride powder. When in use, the bottom end of the feeding mechanism 1 is connected with an aluminum powder container to be fed. Subsequently, the feeding mechanism 1 is started, and the aluminum powder is conveyed into the dredging mechanism 2 by the feeding mechanism 1 and discharged to the other end of the dredging mechanism 2 for processing;

[0054] During feeding, start the pneumatic feeder 101 and the drive assembly 201, so that the aluminum powder enters the connecting pipe 102 along the pneumatic feeder 101 and then discharges from the outlet pipe 106 along the elbow 105. Since the drive assembly 201 will drive the rotating assembly 207 to rotate through the connecting assembly 202 and the telescopic assembly 204 during operation, the aluminum powder blocked at the elbow 105 position can be dredged. At the same time, when the aluminum powder enters the elbow 105, it will first impact the rotating assembly 207 and then impact the anti-collision assembly 206, causing the anti-collision assembly 206 to flip to buffer the impact of the aluminum powder;

[0055] When the pneumatic feeder 101 conveys the material into the elbow 105, since the motor 2011 will also run synchronously, the motor 2011 will drive several connecting blocks 2071 and the spiral blades 2072 to rotate through the slide rod 2043, the connecting rod 2022, the sliding sleeve 2041 and the reinforcing rod 2074. At this time, the adjusting rod 2075 above the connecting block 2071 will squeeze the inclined groove 2054 on one side of the tooth block 2053 through the convex block 2076, causing the mounting plate 2051 to move upward horizontally, so that the lower spiral blade 2072 can uniformly contact the upward moving aluminum powder and reduce the speed of the aluminum powder entering the elbow 105 through the spiral blade 2072;

[0056] When the adjusting rod 2075 contacts the tooth block 2053 below the connecting ring 2052 through the convex block 2076, the tooth block 2053 will be gradually pushed upward due to the extrusion of the inclined groove 2054 opened on one side. As the reinforcing rod 2074 rotates and the convex block 2076 disengages from the contact with the tooth block 2053, the spring 2045 will squeeze the mounting plate 2051 to reset under the action of its own elastic force, so that the anti-collision plate 2061 connected to the mounting plate 2051 on one side is always in a state of swinging up and down. At the same time, when the aluminum powder impacts the anti-collision plate 2061, the anti-collision plate 2061 will flip upward along the rotating shaft 2062, and as the force of the aluminum powder impacting the anti-collision plate 2061 during the up and down swing is different, the coil spring 2064 will drive the anti-collision plate 2061 to continuously deflect and reset along the angle of the rotating shaft 2062 while swinging up and down in the elbow 105;

[0057] When replacing or cleaning the device, only need to disassemble the connector 2012, and then remove the mounting bracket 2078 from the inside of the elbow 105, and then the mounting bracket 2078 can be pulled.
