Abstract
Description
Technical Field
[0001] This invention relates to the field of quantitative conveying technology, specifically a sealed quantitative conveying device for processing soybean protein products. Background Technology
[0002] In the continuous production of soybean protein products, the sealed quantitative conveying device is the core equipment connecting extrusion puffing and subsequent packaging. Its function is to divide the continuously supplied powdery raw materials from upstream into independent units according to preset specifications. Currently, the volumetric disc-type quantitative device is widely used due to its simple structure and reliable operation. It achieves alternating cycles of feeding and discharging through the rotation and indexing of a turntable with quantitative channels.
[0003] However, existing equipment still has many shortcomings in practical applications. First, after drying, soybean protein raw materials contain a large amount of air trapped between the powder particles, and the particle shape is irregular. Before entering the metering orifice, due to the squeezing effect and electrostatic effect, bridging is easily formed at the junction of the hopper and the feed inlet, resulting in incomplete or uneven filling of the metering channel. This directly causes single-time measurement deviation and affects the consistency of product net content. At the same time, the volume of existing metering channels is mostly fixed at the factory, making it difficult to flexibly adjust according to changes in production formula or packaging specifications. It is necessary to stop the machine to replace turntables or parts of different specifications, which is not only time-consuming and labor-intensive, but also reduces the adaptability of the production line. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a sealed quantitative conveying device for processing soybean protein products, which solves the problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A sealed quantitative conveying device for processing soybean protein products includes a conveying mechanism and a quantitative feeding mechanism fixedly mounted on the conveying mechanism. The quantitative feeding mechanism includes a quantitative component, a quantity adjustment component, a stirring component, and a striking component. The quantitative component is connected to the quantity adjustment component, the quantitative component is connected to the stirring component, and the striking component is connected to the stirring component. The metering component is used to intermittently discharge the raw material fed in by the conveying mechanism in a preset volume. The volume adjustment component is used to adjust the amount of raw material discharged from the metering component. The stirring component is used to actively stir the raw material before it enters the metering component to prevent bridging. The tapping component is used to apply periodic vibration force to the feed channel wall of the metering component to guide the raw material to fall accurately into the metering component.
[0006] Preferably, the conveying mechanism includes a conveying shell, a drive motor is fixedly installed at one end of the conveying shell, a drive shaft is fixedly installed at the output end of the drive motor, a first helical blade and a second helical blade with opposite rotation directions are fixedly installed on the drive shaft, a discharge port is opened on the lower end face of the conveying shell, a feed port is opened on the upper end face of the conveying shell, and the first helical blade and the second helical blade are respectively arranged on both sides of the discharge port along the axial direction of the drive shaft.
[0007] Preferably, the metering component includes a feeding box fixedly connected to the discharge port. A connecting block is fixedly installed on the side end face of the feeding box. A feeding motor is fixedly installed on the connecting block. An output rotating rod is fixedly installed on the output end of the feeding motor. An intermittent gear is fixedly installed on the side end face of the output rotating rod. A connecting vertical plate is fixedly installed on the lower end face of the feeding box.

A rotating disk is fixedly installed on the centering shaft and inside the metering shell. An external gear ring is fixedly installed on the side end face of the rotating disk. The intermittent gear intermittently meshes with the external gear ring.
[0008] Preferably, the upper surface of the rotating disk has four metering channels arranged in a ring, the upper surface of the metering shell has a metering hole, and the lower surface of the metering shell has a discharge hole. The metering hole and the discharge hole are staggered in the vertical direction. By intermittently rotating the rotating disk, the corresponding metering channels are aligned with the metering hole and the discharge hole in the same vertical direction, thereby realizing the metering of raw materials.
[0009] Preferably, the adjusting component includes a drive groove formed within a rotating disk, four adjusting blocks slidably mounted inside the drive groove, a lower connecting frame fixedly mounted on the side end face of each adjusting block, an adjusting connecting rod rotatably connected to the lower connecting frame, an electric push rod fixedly mounted on the rotating disk, an adjusting block fixedly mounted on the telescopic rod of the electric push rod, an upper connecting groove formed on the side end face of each adjusting block, and an end of the adjusting connecting rod away from the lower connecting frame rotatably connected to the upper connecting groove. The drive groove communicates with the quantitative channel and is isolated by the adjusting blocks. By adjusting the insertion volume of the adjusting blocks within the quantitative channel, the effective volume of the quantitative channel can be changed.
[0010] Preferably, the stirring assembly includes a large sprocket fixedly mounted on the output rotating rod, a plurality of positioning connecting rods fixedly mounted inside the feeding box, a conical block fixedly mounted on the plurality of positioning connecting rods, a stirring rod fixedly mounted on the lower end face of the conical block, a stirring blade and a small sprocket fixedly mounted on the stirring rod, the small sprocket being positioned above the stirring blade, and the large sprocket being driven by the small sprocket via a chain.
[0011] Preferably, the connecting block has a connecting groove inside, the large sprocket is located inside the connecting groove, and the large sprocket is located above the intermittent gear.
[0012] Preferably, the striking assembly includes an intermittent cam fixedly mounted on the bottom end of an output rotating rod, a stabilizing block fixedly mounted on the side end face of the metering shell, a stabilizing slide rod slidably mounted on the stabilizing block, a force-bearing protrusion fixedly mounted on one end of the stabilizing slide rod, a connecting crossbar fixedly mounted on the side end face of the stabilizing slide rod, a horizontal striking rod fixedly mounted on the inner side of the connecting crossbar, a connecting fixed block fixedly mounted on the inner side of the stabilizing slide rod and inside the connecting crossbar, a return spring fixedly connected to the side end face of the connecting fixed block, the end of the return spring away from the connecting block fixedly connected to the stabilizing block, and the striking end of the horizontal striking rod contacting the outer wall of the metering shell. By striking the metering shell with the horizontal striking rod, the vibration force is transmitted to the metering groove of the rotating disk.
[0013] Preferably, the striking assembly further includes a positioning vertical plate fixedly installed on the feeding box, a connecting shaft rotatably installed on the inner side of the positioning vertical plate, a V-shaped striking rod fixedly installed on the connecting shaft, a power crossbar fixedly installed on the power end of the V-shaped striking rod, a power connecting rod rotatably installed on the power crossbar, one end of the power connecting rod away from the power crossbar being rotatably connected to the other end of the connecting crossbar, and the striking end of the V-shaped striking rod contacting the bottom side wall of the feeding box.
[0014] Preferably, the stabilizing slide bar and the power crossbar are not on the same horizontal plane, and the power connecting rod is arranged at an angle to ensure that when the stabilizing slide bar moves horizontally in a straight line, the V-shaped knocking rod can be rotated by the cooperation of the power connecting rod and the power crossbar.
[0015] This invention provides a sealed quantitative conveying device for processing soybean protein products. Compared with the prior art, it has the following advantages: 1. This invention utilizes the intermittent meshing of an intermittent gear and an external gear ring to drive the rotating disk to rotate at a fixed angle each time, achieving a cyclical action of "feeding through the metering channel → indexing → discharging through the metering channel". This eliminates the need for additional valve control, simplifies the structure, and improves operational reliability. The four metering channels are evenly distributed in a ring, ensuring that while one metering channel is discharging, another is in the feeding position, and the third is in a waiting state, achieving efficient and streamlined operation. At the same time, the metering orifice and the discharge orifice are vertically staggered, effectively eliminating the possibility of the metering orifice and the discharge orifice clashing, ensuring a fixed volume of discharge each time. 2. In this invention, the electric push rod drives the adjusting block to move up and down through extension and retraction. The four adjusting rods simultaneously pull the four lower connecting frames, thereby driving the four adjusting blocks to slide synchronously in their respective quantitative channels. This ensures that the effective volume of the four quantitative channels changes simultaneously and equally, avoiding measurement deviations caused by inconsistent volumes of the quantitative channels. The adjusting component is integrated inside the rotating disk, eliminating the need to stop the machine and manually replace parts. The volume can be adjusted in real time according to the formula requirements during the production process, greatly improving the device's adaptability to different soybean protein product specifications. 3. In this invention, by setting the large sprocket above the intermittent gear and fixing both coaxially to the output rotating rod, the feeding motor can simultaneously drive the stirring component to rotate continuously while driving the quantitative component to operate intermittently, achieving the effect of "one machine, two drives". This reduces the need for additional power source configuration and lowers energy consumption. The stirring blades are located below the small sprocket and extend into the feeding box to actively loosen the raw material before it enters the quantitative feeding hole, effectively breaking the arch bridge structure formed by compression.
[0016] 4. In this invention, when the intermittent cam rotates with the output rotor, it periodically pushes the force-bearing protrusion, causing the stabilizing slide bar to slide outward against the resistance of the return spring. When the intermittent cam passes the highest point, the return spring pulls the stabilizing slide bar back, causing the horizontal striking rod to generate an instantaneous impact on the outer wall of the metering shell, forming periodic vibration. This vibration is directly transmitted to the raw material in the metering channel, which can effectively eliminate the "wall-hanging" phenomenon caused by electrostatic adsorption, ensuring that the metering channel can be completely emptied when it rotates to the discharge hole position, avoiding the accumulation of residual material that affects the accuracy of the next metering, and significantly improving the metering stability of long-term operation.
[0017] 5. This invention achieves a "one rod, two strikes" linkage effect by simultaneously driving the horizontal reciprocating motion of the same stable sliding rod to strike the metering shell and the V-shaped striking rod to strike the bottom side wall of the feeding box. This simplifies the structure of the striking components and ensures the consistency of the vibration source's action. The V-shaped striking rod swings around the connecting shaft, and its striking end acts on the outer wall of the bottom of the feeding box, which can effectively shake off large-diameter materials attached to the area and prevent blockage caused by changes in cross-sectional area.

Detailed Implementation
[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Please see Figures 1-9This invention relates to a sealed quantitative conveying device for processing soybean protein products, comprising a conveying mechanism 1 and a quantitative feeding mechanism 2 fixedly mounted on the conveying mechanism 1. The quantitative feeding mechanism 2 includes a quantitative component 21, an adjusting component 22, a stirring component 23, and a striking component 24. The quantitative component 21 is connected to the adjusting component 22, the stirring component 23, and the striking component 24. The quantitative component 21 is used to intermittently and quantitatively discharge the raw material fed into the conveying mechanism 1 according to a preset volume. The adjusting component 22 is used to adjust the amount of raw material discharged from the quantitative component 21. The stirring component 23 is used to actively agitate the raw material before it enters the quantitative component 21 to prevent bridging. The striking component 24 is used to apply periodic vibration force to the wall of the feeding channel of the quantitative component 21 to guide the raw material to fall accurately into the quantitative component 21. The coordinated operation of the conveying mechanism 1 and the quantitative feeding mechanism 2 achieves a smooth transition from continuous conveying to intermittent quantitative feeding of soybean protein products.
[0022] Please see Figures 1-2 The conveying mechanism 1 includes a conveying shell 11. A drive motor 12 is fixedly installed at one end of the conveying shell 11. A drive shaft 13 is fixedly installed at the output end of the drive motor 12. A first spiral blade 14 and a second spiral blade 15 with opposite rotation directions are fixedly installed on the drive shaft 13. A discharge port 16 is opened on the lower end face of the conveying shell 11, and a feed port 17 is opened on the upper end face of the conveying shell 11. The first spiral blade 14 and the second spiral blade 15 are respectively arranged on both sides of the discharge port 16 along the axial direction of the drive shaft 13 to ensure that when the raw material is delivered to the position of the discharge port 16, excessive raw material is avoided from clogging the tail end of the conveying shell 11.
[0023] Please see Figures 3-4The metering component 21 includes a feeding box 2101 fixedly connected to the discharge port 16. A connecting block 2102 is fixedly installed on the side end face of the feeding box 2101. A feeding motor 2103 is fixedly installed on the connecting block 2102. An output rotating rod 2104 is fixedly installed at the output end of the feeding motor 2103. An intermittent gear 2105 is fixedly installed on the side end face of the output rotating rod 2104. A connecting vertical plate 2106 is fixedly installed on the lower end face of the feeding box 2101. A metering shell 2107 is fixedly installed at the bottom end of the connecting vertical plate 2106. A centering shaft 20108 is rotatably mounted on the inner bottom of the measuring shell 2107. A rotating disk 2109 is fixedly mounted on the centering shaft 20108 and inside the measuring shell 2107. An external gear ring 2110 is fixedly mounted on the side end face of the rotating disk 2109. An intermittent gear 2105 intermittently meshes with the external gear ring 2110. Four metering slots 2111 arranged in a ring are opened on the upper end face of the rotating disk 2109. A metering hole 2112 is opened on the upper end face of the measuring shell 2107. A discharge port is opened on the lower end face of the measuring shell 2107. The feed orifice 2113, the metering feed orifice 2112, and the discharge feed orifice 2113 are vertically offset from each other. Through the intermittent rotation of the rotating disk 2109, the corresponding metering trough 2111 is aligned vertically with the metering feed orifice 2112 and the discharge feed orifice 2113, respectively, enabling quantitative conveying of raw materials. Driven by the unidirectional intermittent meshing of the intermittent gear 2105 and the external gear ring 2110, the rotating disk 2109 rotates at a fixed angle each time, achieving the process of "feeding into the metering trough 2111 → indexing → discharging from the metering trough 2111". The cyclic operation eliminates the need for additional valve control, simplifying the structure and improving operational reliability. The four metering channels 2111 are evenly distributed in a ring, ensuring that while one metering channel 2111 is discharging material, another metering channel 2111 is in the feeding position, and the third is in a waiting state, achieving efficient and streamlined operation. At the same time, the metering holes 2112 and the discharge holes 2113 are vertically staggered, effectively eliminating the possibility of cross-contamination between the metering holes 2112 and the discharge holes 2113, and ensuring a fixed volume of discharge each time.
[0024] Please see Figures 6-7The adjustment assembly 22 includes a drive groove 2201 formed within a rotating disk 2109. Four adjustment blocks 2202 are slidably mounted inside the drive groove 2201. A lower connecting frame 2203 is fixedly mounted on the side end face of each adjustment block 2202. An adjustment connecting rod 2204 is rotatably connected to the lower connecting frame 2203. An electric push rod 2205 is fixedly mounted on the rotating disk 2109. An adjustment block 2206 is fixedly mounted on the telescopic rod of the electric push rod 2205. An upper connecting groove 2207 is formed on the side end face of the adjustment block 2206. The end of the adjustment connecting rod 2204 away from the lower connecting frame 2203 is rotatably connected to the upper connecting groove 2207. The drive groove 2201 communicates with the quantitative channel 2111 and is isolated by the adjustment blocks 2202. The adjustment is achieved by adjusting the adjustment... The insertion volume of the adjustment block 2202 into the quantitative channel 2111 can change the effective volume of the quantitative channel 2111. The electric push rod 2205 drives the adjustment block 2206 to move up and down through extension and retraction. The four lower connecting frames 2203 are pulled synchronously through the four adjustment connecting rods 2204, thereby driving the four adjustment blocks 2202 to slide synchronously in their respective quantitative channels 2111. This ensures that the effective volume of the four quantitative channels 2111 changes by the same amount at the same time, avoiding the measurement deviation caused by the inconsistency of the volume of each quantitative channel 2111. This adjustment component is integrated inside the rotating disk 2109. There is no need to stop the machine and manually disassemble and replace parts. It can be adjusted according to the needs of personnel during the production process. The electric push rod 2205 and the quantitative shell 2107 are rotatably installed.
[0025] Please see Figure 5The mixing assembly 23 includes a large sprocket 2301 fixedly mounted on the output rotating rod 2104. Multiple positioning rods 2302 are fixedly mounted inside the feeding box 2101. A conical block 2303 is fixedly mounted on each of the positioning rods 2302. A mixing rod 2304 is fixedly mounted on the lower end face of the conical block 2303. A mixing blade 2305 and a small sprocket 2306 are fixedly mounted on the mixing rod 2304. The small sprocket 2306 is positioned above the mixing blade 2305. The large sprocket 2301 is driven by a chain to the small sprocket 2306. A connecting groove 2307 is provided inside the connecting block 2102. The large sprocket 2301 is positioned inside the connecting groove 2307. Above the intermittent gear 2105, the large sprocket 2301 is positioned above the intermittent gear 2105, and both are coaxially fixed to the output rotor 2104. This allows the feeding motor 2103 to drive the mixing component 23 to rotate continuously while driving the quantitative component 21 to operate intermittently, achieving a "one machine, two drives" effect. This reduces the need for additional power sources and lowers energy consumption. The mixing blades 2305 are located below the small sprocket 2306 and extend into the feeding box 2101. They actively loosen the raw material before it enters the quantitative feeding hole 2112, effectively breaking the arch structure formed by compression. The conical block 2303 can guide the material at the top of the feeding box 2101 to the surrounding areas, preventing accumulation in the central dead zone and further improving the uniformity of feeding.
[0026] Please see Figures 8-9The striking assembly 24 includes an intermittent cam 2401 fixedly mounted on the bottom end of an output rotating rod 2104; a stabilizing block 2402 fixedly mounted on the side end face of a metering housing 2107; a stabilizing slide rod 2403 slidably mounted on the stabilizing block 2402; a force-bearing protrusion 2404 fixedly mounted on one end of the stabilizing slide rod 2403; a connecting crossbar 2405 fixedly mounted on the side end face of the stabilizing slide rod 2403; a horizontal striking rod 2406 fixedly mounted on the inner side of the connecting crossbar 2405; a connecting fixed block 2407 fixedly mounted on the inner side of the stabilizing slide rod 2403 and inside the connecting crossbar 2405; a return spring 2408 fixedly connected to the side end face of the connecting fixed block 2407; the end of the return spring 2408 away from the connecting block 2102 fixedly connected to the stabilizing block 2402; and the striking end of the horizontal striking rod 2406 contacting the outer wall of the metering housing 2107. The horizontal striking rod 2406 strikes the metering shell 2107, transmitting the vibration force to the metering channel 2111 of the rotating disk 2109. As the intermittent cam 2401 rotates with the output rotating rod 2104, it periodically pushes the force-bearing protrusion 2404, causing the stabilizing slide rod 2403 to slide outward against the resistance of the return spring 2408. When the intermittent cam 2401 passes the highest point, the return spring 2408 pulls the stabilizing slide rod 2403 back, causing the horizontal striking rod 2406 to generate an instantaneous impact on the outer wall of the metering shell 2107, forming periodic vibration. This vibration is directly transmitted to the raw material in the metering channel 2111, effectively eliminating the "wall-hanging" phenomenon caused by electrostatic adsorption. This ensures that the metering channel 2111 can be completely emptied when it rotates to the position of the discharge hole 2113, avoiding the accumulation of residual material that affects the accuracy of the next metering, and significantly improving the metering stability of long-term operation.
[0027] Please see Figures 8-9The striking assembly 24 also includes a positioning vertical plate 2409 fixedly installed on the feed box 2101. A connecting shaft 2410 is rotatably installed on the inner side of the positioning vertical plate 2409. A V-shaped striking rod 2411 is fixedly installed on the connecting shaft 2410. A power crossbar 2412 is fixedly installed on the power end of the V-shaped striking rod 2411. A power connecting rod 2413 is rotatably installed on the power crossbar 2412. One end of the power connecting rod 2413 away from the power crossbar 2412 is rotatably connected to the other end of the connecting crossbar 2405. The striking end of the V-shaped striking rod 2411 contacts the bottom side wall of the feed box 2101. The stabilizing slide bar 2403 and the power crossbar 2412 are not on the same horizontal plane. The power connecting rod 2413 is arranged at an angle. To ensure the horizontal linear motion of the stabilizing slide bar 2403, the V-shaped knocking bar 2411 can be rotated by the cooperation of the power connecting rod 2413 and the power crossbar 2412. Through the horizontal reciprocating motion of the same stabilizing slide bar 2403, the horizontal knocking bar 2406 is driven to knock the metering shell 2107 and the V-shaped knocking bar 2411 is driven to knock the bottom side wall of the feed box 2101, realizing the linkage effect of "one bar, two knocks". This simplifies the structure of the knocking component 24 and ensures the consistency of the vibration source action. The V-shaped knocking bar 2411 swings around the connecting shaft 2410, and its knocking end acts on the outer wall of the bottom of the feed box 2101, which can effectively shake off large-diameter materials attached to the area and prevent blockage caused by changes in cross-sectional area.
[0028] Working principle: During use, the drive motor 12 drives the drive shaft 13 to rotate, which in turn drives the first spiral blade 14 and the second spiral blade 15 to rotate, ensuring that when the raw material is delivered to the outlet 16, excessive raw material is avoided from clogging the tail end of the conveying shell 11, thus providing a stable material pressure basis for subsequent quantitative accuracy. The feeding motor 2103 drives the intermittent gear 2105 on the output shaft to rotate. The intermittent gear 2105 and the external gear ring 2110 engage in a unidirectional intermittent meshing, causing the rotating disk 2109 to rotate a fixed angle each time. This achieves a cyclical action of "feeding through the quantitative channel 2111 → indexing → discharging through the quantitative channel 2111". The four quantitative channels 2111 are evenly distributed in a ring, ensuring that while one channel is discharging, another is in the feeding position, and the third is in a waiting state. This design enables efficient, streamlined operations. Simultaneously, the metering orifice 2112 and the discharge orifice 2113 are vertically offset, effectively preventing any possibility of them communicating and ensuring a fixed volume for each discharge. When the output shaft rotates, it drives the large sprocket 2301 to rotate. The large sprocket 2301 is then connected to the small sprocket 2306 via a chain. The small sprocket 2306, when rotating, drives the stirring blades 2305 on the stirring rod 2304, thus loosening the raw materials in the feed box 2101. When the shaft rotates, it also drives the intermittent cam 2401 to rotate. This periodic push of the force-bearing protrusion 2404 causes the stabilizing slide bar 2403 to slide outwards against the resistance of the return spring 2408. Once the intermittent cam 2401 passes its highest point, the return spring 2408 pulls the stabilizing slide bar 2403 back, causing the horizontal striking rod 2406 to momentarily impact the outer wall of the metering shell 2107, creating periodic vibrations. These vibrations are directly transmitted to the raw material in the metering channel 2111, effectively breaking the "wall-hanging" phenomenon caused by electrostatic adsorption. The horizontal reciprocating motion of the same stabilizing slide bar 2403 simultaneously drives the horizontal striking bar 2406 to strike the metering shell 2107 and the V-shaped striking bar 2411 to strike the bottom side wall of the feeding box 2101, achieving the linkage effect of "one bar, two strikes". This simplifies the structure of the striking component 24 and ensures the consistency of the vibration source's action. The V-shaped striking bar 2411 swings around the connecting shaft 2410, and its striking end acts on the outer wall of the bottom of the feeding box 2101, which can effectively shake off large-diameter materials attached to the area and prevent blockage caused by changes in cross-sectional area. When it is necessary to change the effective volume of the quantitative channel 2111, the electric push rod 2205 drives the adjusting block 2206 to move up and down through extension and retraction. The four adjusting connecting rods 2204 simultaneously pull the four lower connecting frames 2203, thereby driving the four adjusting blocks 2202 to slide synchronously in their respective quantitative channels 2111. This ensures that the effective volume of the four quantitative channels 2111 changes by the same amount at the same time, avoiding measurement deviations caused by inconsistent volumes of the quantitative channels 2111. This adjusting component is integrated inside the rotating disk 2109, eliminating the need for manual replacement of parts during production. It can be adjusted according to personnel needs during the production process.
