Description

Technical Field

[0001] This invention relates to the field of packaging technology, specifically to a granular material dispensing device. Background Technology

[0002] Granular materials are used in various fields such as food, pharmaceuticals, aquaculture, and chemicals. The production of granular materials mostly involves granulating powdered raw materials using a pelletizing process. After the granules are produced, they need to be packaged. In the packaging stage, the material needs to be divided into quantitative portions according to different requirements and then fed into subsequent processing components. Current packaging mechanisms mostly suffer from two problems: firstly, the problem of clogging in the granular material supply; and secondly, the problem of granular material crushing due to the movement of the feed gate during quantitative feeding.

[0003] Regarding the first problem, granular materials are inherently fluid, so they will move towards lower-level openings in a flowing manner. However, during their natural descent, the feed inlet often becomes blocked, requiring external force to be applied to the material to continue flowing. While using a screw conveyor-like propulsion structure or other mechanisms that directly apply propulsive force to the granular material itself can restore its flow when blocked, this process will cause some of the granules to pulverize, leading to significant economic losses in continuous industrial production.

[0004] Regarding the second question, most of the existing dispensing mechanisms use a sliding structure for the material gate. During the opening and closing of the material gate, the material is easily crushed and turned back into powder due to the squeezing of the material gate, resulting in losses in the production process.

[0064] Compared with existing technologies, this solution has the following advantages: It combines a uniquely structured feeding mechanism and a discharging mechanism. The feeding mechanism solves the problems of blockage and material crushing during the feeding process of granular materials, while the discharging mechanism solves the problems of material crushing at the quantitative filling machine and material gate of granular materials.

[0065] The feeding mechanism of this solution adopts a three-section bin structure from top to bottom. The topmost bin is fixed, the middle bin rotates, and the bottommost bin slides horizontally. The horizontal movement of the third bin drives the second bin to oscillate back and forth on its own axis, causing the granular material inside the bin to continuously shake, thereby solving the problem of granular material clogging the bin's discharge port.

[0066] This solution uses a scraping plate as the material leveling mechanism on the material box. The movement path of the scraping plate is a combination of its own rotation and oscillation with the translation of the third material bin. This allows the lower edge of the scraping plate to form a relatively gentle arc path during scraping. This movement path will not cause the internal granular material to be crushed, which can effectively reduce the problem of granular material crushing during feeding.

[0067] The feeding mechanism in this design uses adjusting blocks to regulate the space within the feeding trough, using this space as the limiting space for material feeding. Each feeding trough has an independent adjusting block, thus meeting the different feeding volume requirements of multiple troughs. A sealing element is installed on the lower side of the feeding trough, and its rotation serves as the trough's closing structure. This avoids squeezing and grinding the material when closing the trough, effectively preventing pulverization due to the closed feeding port.

[0068] This device minimizes the crushing of particulate materials through the three methods described above, thereby improving the metering accuracy of the packaged particulate materials and enhancing product quality. Attached Figure Description

[0082] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0083] Please see Figures 1-3 This application provides the following technical solutions:

[0084] A pellet material dispensing device includes a feeding mechanism 1 and a dispensing mechanism 2. The feeding mechanism 1 includes a plurality of longitudinally arranged hoppers, which form a top-to-bottom granular material channel. The dispensing mechanism 2 is located below the feeding mechanism 1 and is used to carry the material falling from the feeding mechanism 1 and to dispense it in a quantitative manner.

[0085] The feeding mechanism 1 specifically includes a first hopper 11, a second hopper 12, and a third hopper 13 arranged sequentially from top to bottom. The first hopper 11 is fixedly mounted on the feeding frame 15, with a first inlet at the top and a first outlet at the bottom. The second hopper 12 is located below the first hopper 11, with the first outlet extending into the interior of the second hopper 12, and the second hopper 12 is rotatably connected to the feeding frame 15. The third hopper 13 is located below the second hopper 12, with the bottom end of the second hopper 12 extending into the interior of the third hopper 13, and the third hopper 13 is horizontally slidably connected to the feeding frame 15. Both the second hopper 12 and the third hopper 13 are through-type discharge structures from top to bottom. A material-pushing plate assembly 14 is provided on the outside of the third hopper 13, and the material-pushing plate assembly 14 includes several material-pushing plates 141 located on the outside of the third hopper 13. There is a gap between the lower edge of the third hopper 13 and the upper surface of the supporting structure of the feeding mechanism 2, that is, there is a gap between the third hopper 13 and the upper side of the bottom of the material box 21 in the feeding mechanism 2.

[0086] The first discharge port is an elongated opening; the axis of rotation of the second hopper 12 is parallel to the length direction of the first discharge port; the sliding direction of the third hopper 13 is perpendicular to the length direction of the first discharge port. The first hopper 11, the second hopper 12 and the third hopper 13 are all funnel-shaped structures that gradually change from top to bottom.

[0087] This design employs a three-layer silo structure. The first silo 11 serves as the primary material receiving silo, filled with granular materials via a feed pipeline. A sensor on the upper side of the first silo 11 provides feedback on the material height. The lower outlet of the first silo 11 is relatively large, preventing granular material blockage. Considering subsequent processing of the granular materials, the material's falling speed needs to be limited; therefore, the second silo 12 has a small outlet. The reciprocating sliding motion of the third silo 13 causes the second silo 12 to oscillate, preventing material blockage. The third silo 13 also limits the material's falling range, facilitating material retrieval during subsequent processing. This mechanism uses the horizontally movable third silo 13 to drive the oscillating motion of the second silo 12. The combined action of these two silos allows the third silo 13 to feed material to the lower feeding mechanism 2, while the oscillating motion of the second silo 12 during this process prevents material blockage.

[0088] Based on the above implementation scheme, the second hopper 12 includes a second hopper body 121. The second hopper body 121 is hollow inside and has a funnel-shaped structure with a large opening at the top and a small opening at the bottom. The lower part of the second hopper body 121 extends into the third hopper 13. Actuating grooves 127 are formed at the lower ends of the two side walls of the second hopper body 121 perpendicular to its rotation axis. The actuating grooves 127 are through grooves penetrating the side walls of the second hopper body 121. Actuating rod 131 is fixedly installed inside the third hopper 13 corresponding to the actuating grooves 127. The actuating rod 131 extends into the actuating grooves 127, and the axis of the actuating rod 131 is parallel to the rotation axis of the second hopper body 121. Through this structure, the actuating rod 131, in conjunction with the actuating grooves 127, shakes the second hopper 12, reducing the collision between the walls of the third hopper 13 and the walls of the second hopper 12. This reduces the impact on the material while allowing the second hopper 12 to shake, and also extends the service life of the hopper.

[0089] Based on the above implementation plan, see Figure 2 and Figure 4 The feeding mechanism 1 also includes a hopper drive component, which is linked to the third hopper 13 and is used to drive the third hopper 13 to slide in the horizontal direction.

[0090] The hopper drive assembly includes a hopper slide rail 161, a hopper motor 162, a hopper lead screw 163, and a hopper connector 164. The hopper slide rail 161 is a horizontal track mounted on the feed rack 15. The third hopper 13 is slidably connected to the hopper slide rail 161, and the third hopper 13 performs a horizontal reciprocating sliding motion relative to the feed rack 15 along the hopper slide rail 161. The hopper motor 162 is fixedly mounted on the feed rack 15. The motor shaft of the hopper motor 162 is fixedly connected to the hopper lead screw 163, and the hopper motor 162 drives the hopper lead screw 163 to rotate.

[0091] The hopper connector 164 includes a horizontal plate with a hopper screw 163 threadedly connected to its center. A connecting rod is located at each end of the plate; one end of the connecting rod is rotatably connected to the support frame of the third hopper 13, and the other end is rotatably connected to the horizontal plate. The reciprocating motion of the hopper motor 162 drives the third hopper 13 to move horizontally via the screw. The lower two edges of the third hopper 13 are in contact with the upper side of the material box 21. When the third hopper 13 faces... Figure 5 When the third hopper 13 moves to the right, its left edge scrapes the top of the hopper 211, thus ensuring that the amount of material discharged from the hopper 211 is the amount that its internal space can hold.

[0092] During the movement of the third hopper 13, the lower part of the second hopper 12 swings, causing the material inside the second hopper 12 to shake, which makes it less likely to cause blockage. Moreover, this method does not apply a direct pushing force to the granular material, making it less likely to cause material breakage.

[0093] The feeding mechanism 2 includes a material box 21, an adjusting component, and a closing component 23. The bottom of the material box 21 is flat, and several material grooves 211 are provided on the bottom of the box. The material grooves 211 are through grooves that pass through the bottom of the box. The adjusting component includes an adjusting block 221, which is slidably connected to the material grooves 211. The adjusting component can adjust the size of the space inside the material grooves 211 by moving the adjusting block 221. The closing component 23 is located on the lower side of the material box 21 and includes several closing members 231. The number of closing members 231 corresponds to the number of material grooves 211. The closing members 231 can be rotated to close the lower side of the material grooves 211.

[0094] This solution achieves continuous feeding of granular materials through the feeding mechanism 1. The amount of material falling into the trough 211 is adjusted by sliding the adjusting block 221. Sliding the adjusting block 221 reduces the internal volume of the trough 211, thus decreasing the amount of material falling into each trough 211 at a time, and vice versa. This solution uses a rotating closing member 231 to close the lower side of the trough 211. Controlling the opening and closing of the trough 211 by rotating the closing action better prevents the granular materials from being crushed.

[0095] Based on the above implementation plan, see Figures 5-7 Two material-pushing plates 141 are provided, located on both sides of the third material bin 13 in the direction of movement, and the distance between the upper ends of the two material-pushing plates 141 is smaller than the distance between the lower ends. The material-pushing plate assembly 14 also includes two side connecting plates 142, located between the ends of the two material-pushing plates 141. The side connecting plates 142 and the material-pushing plates 141 form a combined structure with an open top and bottom. The material-pushing plates 141 are arranged in an approximately "V" shape. The upper part of the side connecting plate 142 is rotatably connected to the external support structure of the third material bin 13 through a material-pushing shaft 144. The side connecting plate 142 is linked with the material-pushing drive assembly 143, which drives the side connecting plate 142 to swing back and forth around the material-pushing shaft 144. The upper part of the material-pushing plate 141 forms an outward-flared flange structure, and the material-pushing plate 141 can be made of an elastic material such as rubber.

[0096] A third hopper frame 132 is provided outside the third hopper 13. One side of the third hopper 13 is fixedly connected to the third hopper 13, and the other side is linked to the hopper drive assembly. The third hopper frame 132 can be driven by the hopper drive assembly to perform reciprocating translational motion. The feeding shaft 144 is rotatably connected to the third hopper frame 132 and performs reciprocating translational motion synchronously with the third hopper frame 132. The feeding drive assembly 143 includes a feeding cylinder 1431, which is a pneumatic cylinder. Its fixed part is rotatably connected to the third hopper frame 132. The feeding cylinder 1431 and the feeding shaft 144 are linked by a feeding connecting block 1432. One end of the feeding connecting block 1432 is rotatably connected to the movable end of the feeding cylinder 1431, and the other end is fixedly connected to the feeding shaft 144.

[0097] Through this structure, when the hopper drive assembly drives the third hopper frame 132 to translate, the material feeding assembly 14 translates synchronously. During this translation, the material feeding cylinder 1431 drives the side connecting plate 142 to swing, thereby causing the material feeding plate 141 to swing. Specifically, the third hopper 13 faces... Figure 5 When the left side moves, the feeding cylinder 1431 retracts, at which time the left feeding plate 141 rises, and the right feeding plate 141 abuts against the upper side of the material box 21 of the feeding mechanism 2. This action pushes the granular material into the trough 211 on the material box 21. When the third material bin 13 moves towards... Figure 5 When the right side moves, the feeding cylinder 1431 extends, and the left feeding plate 141 abuts against the upper side of the material box 21. This action flattens the upper side of the material trough 211, thus ensuring that the amount of material discharged from the material trough 211 is only the granular material inside its internal space.

[0098] This design uses a material-leveling plate 141 as the material-leveling mechanism on the material box 21. The movement path of the material-leveling plate 141 during the leveling process is a curve formed by its own rotational oscillation and the translational movement of the third material bin 13. The first part of this curve is arc-shaped, while the latter part is a translational movement that conforms to the upper side of the material box 21. Because the first part of this arc combines oscillation and translation, the movement path formed by the lower edge of the material-leveling plate 141 is gentler than that of a typical oscillation. This allows the material to be pushed forward with minimal crushing of the internal granular material, thus preventing granular material pulverization during the leveling of the upper side of the material trough 211.

[0099] Based on the above implementation scheme, two dust-collecting plates 122 are installed on both sides of the exterior of the second hopper 121. The dust-collecting plates 122 are symmetrically arranged, and a gap is left between the dust-collecting plates 122 and the outer wall of the second hopper 121. A hopper exhaust pipe assembly 123 is installed on the dust-collecting plates 122. By installing the dust-collecting plates 122, combined with a negative pressure suction device, dust inside the hopper can be guided out of the hopper. See also Figure 5The second hopper 12 also includes hopper baffles 124 fixedly disposed on opposite sides of the opening at the upper end of the second hopper body 121. The hopper baffles 124 form a flanged structure facing inwards from the opening. A dust suction baffle 125 is disposed at the upper end of the dust suction plate 122 corresponding to the hopper baffles 124. The dust suction baffle 125 is located above the hopper baffles 124 and is inclined towards the first hopper 11. Figure 4 As shown, the installation of the hopper baffle 124 and the dust suction baffle 125 can reduce the amount of dust floating upward from the second hopper 12 to a certain extent. Furthermore, the dust suction baffle 125 can also draw out and discharge the dust floating from the upper part of the second hopper 12.

[0100] Based on the above implementation plan, see Figure 5 Both suction plates 122 have bent plates at their lower ends, bending away from the second chamber 121. These bent plates form a funnel-shaped structure, with the larger opening at the lower end. The distance between the inner walls of the openings at the lower edges of the two suction plates 122 is greater than or equal to the distance between the outer walls of the upper end of the third chamber 13. This structure allows the suction plates 122 to primarily attract dust from the upper part of the second chamber 12, while attracting dust from the lower part of the third chamber 13. This reduces dust dispersion from both the second and third chambers.

[0101] Based on the above implementation scheme, a dust suction chamber 126 is provided on the dust suction plate 122. The dust suction chamber 126 is a cavity recessed from the dust suction plate 122 away from the second bin 121. The dust suction chamber 126 is located between the bin baffle 124 and the bending plate, and the bin exhaust pipe is installed on the cavity wall of the dust suction chamber 126. A filter screen is installed inside the dust suction chamber 126. By setting the dust suction chamber 126, the suction force generated by the negative pressure can be better utilized to gather dust into the dust suction chamber 126. With the filter screen, larger particles are easily blocked. The blocked particles can fall back into the third bin 13 through the gap between the dust suction plate 122 and the outer wall of the second bin 121.

[0102] Based on the above implementation plan, see Figure 2 The feeding frame 15 serves as the supporting structure for the entire device. A slider-rail assembly 151 is installed at the lower part of the feeding frame 15, and the feeding frame 15 is connected to the movable end of the main adjusting cylinder 152. This structure facilitates the combination and installation of this device with other components, and the position of the entire device can be adjusted more conveniently via the main adjusting cylinder 152.

[0103] Based on the above implementation plan, see Figures 8-10The material troughs 211 are arranged in a straight line array along the length of the material box 21. The axis of rotation of the closure member 231 is parallel to the length of the material box 21. The material trough 211 is a long rectangular trough, and the adjusting block 221 is a rectangular strip block corresponding to the material trough; the two parallel side walls of the adjusting block 221 are in contact with the two inner walls of the material trough 211.

[0104] The lower side of the material trough 211 is flat, the lower side of the adjusting block 221 is flush with the lower side of the material trough 211, and the upper side of the sealing member 231 is flat; when the sealing member 231 rotates upward, the sealing member 231 is in contact with the lower side of the material trough 211.

[0105] This solution adjusts the material discharge rate of the trough 211 by sliding the adjusting block 221. Sliding the adjusting block 221 reduces the internal volume of the trough 211, thus decreasing the amount of material discharged at one time in each trough 211, and vice versa. The solution also uses a rotating closing member 231 to seal the lower side of the trough 211. Controlling the opening and closing of the trough 211 by rotating the closing action better prevents the crushing of particulate materials.

[0106] When the third hopper 13 pushes the granular material above the trough 211 through movement, and the third hopper 13 moves in the opposite direction to scrape the top of the trough 211 flat, the sealing part 231 flips down and opens, and the material in the trough 211 falls down, thereby realizing the feeding of a single quantitative material.

[0107] Based on the above implementation plan, see Figure 10 The adjustment assembly includes several adjustment motors 222, one of which is provided for each adjustment block 221. The adjustment motors 222 and the adjustment blocks 221 are connected by an adjustment transmission assembly 223, which serves as the power transmission component. The adjustment transmission assembly 223 includes an adjustment screw 2231 and a transmission gear set 2232. The adjustment screw 2231 is threadedly connected to the adjustment block 221, and its axis is parallel to the length direction of its corresponding feed trough 211. The transmission gear set 2232 is a bevel gear combination used for transmission between the motor shaft of the adjustment motor 222 and the adjustment screw 2231. One bevel gear in the bevel gear combination is connected to the motor shaft of the adjustment motor 222, and the other bevel gear is fixedly connected to one end of the adjustment screw 2231. Preferably, the enclosure assembly 23 further includes:

[0108] Based on the above implementation scheme, the sealing assembly 23 further includes a sealing rotating shaft 232. One sealing rotating shaft 232 is provided, and all sealing components 231 are fixedly connected to the sealing rotating shaft 232. The axis of the sealing rotating shaft 232 is parallel to the length direction of the material box. The sealing rotating shaft 232 is driven to rotate by the sealing drive assembly 233. The sealing drive assembly 233 includes a sealing connecting component 2331 and a sealing power component 2332. The sealing power component 2332 is a cylinder. One end of the sealing connecting component 2331 is fixedly connected to the sealing rotating shaft 232, and the other end is rotatably connected to the movable end of the sealing power component 2332. The fixed end of the sealing power component 2332 is rotatably connected to the external support structure.

[0109] Based on the above implementation scheme, a downward air duct 24 is provided on one side of the material box. The downward air duct 24 includes a main pipe, and a branch pipe is provided on the main pipe corresponding to each material trough 211. Each branch pipe extends to the bottom of a material trough 211, and the end of the branch pipe is facing the closure member 231. The downward air duct 24 is connected to a negative pressure device, and the negative pressure air duct is used to attract the dust floating below the material trough 211.
