Description

Technical Field

[0001] This invention relates to the field of raw material screening technology, specifically to a raw material screening device for processing spicy seasonings. Background Technology

[0002] Raw material screening is the process of separating raw materials into different particle sizes by using a sieve with a certain size of mesh. In the processing of spicy seasonings, raw material screening devices are required to screen the raw materials and separate seasonings of different particle sizes.

[0003] In existing technologies, when raw materials need to be graded and screened for different particle sizes, a multi-layer filter screen screening method is usually adopted. In this multi-layer screening method, the raw materials are poured in from the top, and then the raw materials fall through the filter screen layer by layer to complete the screening. This screening method requires the installation of multiple screens, that is, the device needs to occupy a large longitudinal space, and the overall device is large. It also needs to be equipped with a high-power motor for vibration, resulting in high processing costs.

[0004] Therefore, a raw material screening device for processing spicy seasonings is proposed to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to provide a raw material screening device for processing spicy seasonings, so as to solve the problem that the device proposed in the background art requires a large longitudinal space, and the device as a whole is large and requires a high-power motor for vibration, resulting in high processing costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a raw material screening device for processing spicy seasonings, comprising a shell, a screening component, a receiving component, a blocking component, and a discharging component. The shell has a top cover, and a first motor is fixedly connected to the top of the top cover. The output end of the first motor passes through the top cover and extends to the lower side. A first rotating shaft is fixedly connected to the output end of the first motor, and a connecting sleeve is fixedly connected to the outer surface of the first rotating shaft. The screening component is fixedly connected to the outer surface of the first rotating shaft and includes a turntable. Multiple dividing grooves are evenly distributed on the top of the turntable. Each of the multiple dividing grooves has an outer frame inside. A discharge plate is fixedly connected to the inner surface of one of the outer frames, and screening plates are fixedly connected to the inner surfaces of the other multiple outer frames. The receiving component is located inside the shell and includes a support plate. The blocking component is fixedly connected to the inner surface of the shell and includes a bracket. A baffle is fixedly connected to the outer surface of the bracket. The discharging component is fixedly connected to the top cover and includes a discharging pipe. A storage hopper is fixedly connected to the top of the discharging pipe.

[0007] Preferably, the outer surface of the outer frame is in contact with the inner surface of the partition groove, the discharge plate, the screening plate, the outer frame and the top of the turntable are all flush, the surfaces of the multiple screening plates are respectively provided with screen holes of different sizes, and the turntable is located above the support plate.

[0008] By adopting the above technical solution, through the combined use of the discharge plate and the screening plate above the turntable, the screening plates are arranged from the side of the discharge plate, and the filter apertures are arranged from fine to coarse to form different screening levels.

[0009] Preferably, the inner surface of the partition groove is symmetrically provided with limiting grooves, the outer surface of the outer frame is symmetrically fixedly connected with limiting blocks, the outer surface of the limiting blocks is slidably connected to the inner surface of the limiting grooves, a plurality of springs are uniformly fixedly connected to the bottom of the outer frame, two retaining rings are fixedly connected to the bottom of the turntable, the lower end face of the spring is fixedly connected to the top of the retaining ring, a plurality of discharge buckets are uniformly fixedly connected between the bottoms of the two retaining rings, and the number of discharge buckets is the same as that of the outer frame and their positions correspond to each other.

[0010] By adopting the above technical solution, the outer frame can slide along the limiting groove through the connection of the limiting block when moving up and down, thereby limiting the displacement trajectory of the outer frame. At the same time, the initial position of the outer frame can be limited. The spring rebound force is used to press the limiting block against the top position in the limiting groove, thereby ensuring that under normal conditions, the discharge plate and each screening plate are flush with the turntable, ensuring that no material is missed during material transfer.

[0011] Preferably, the top of the support plate is provided with a plurality of placement slots, and each of the plurality of placement slots contains a collection box. The collection boxes are located below the discharge hopper, and the number of collection boxes is the same as the number of discharge hoppers and their positions correspond to each other.

[0012] By adopting the above technical solution, the screened raw materials will fall into the corresponding collection box below through the discharge hopper, thus completing the first screening of the raw materials.

[0013] Preferably, a through hole is provided at the center of the top of the support plate, and a sliding sleeve is fixedly connected to the inner surface of the through hole. The sliding sleeve is slidably connected to the connecting sleeve. Multiple universal wheels are evenly fixedly connected to the bottom of the support plate. A slide rail is fixedly connected to the bottom of the outer shell. The universal wheels are located inside the slide rail. Multiple tooth blocks are evenly fixedly connected to the bottom of the slide rail. The tooth blocks have a triangular cross-section.

[0014] By adopting the above technical solution, as the support plate rotates, it will drive the caster to move along the slide rail. After passing the inclined surface of the toothed block, the caster will disengage from the toothed block. At this time, the support plate, which was lifted, will fall back to the initial position at the bottom. As the support plate rotates, the caster repeatedly passes the toothed block position, and the support plate is lifted and falls, which will cause the support plate and the collection box to vibrate. Under the action of vibration, the raw materials accumulated in the collection box are dispersed, and the raw materials can be accumulated more evenly in the collection box, avoiding the loss caused by uneven accumulation and overflow of raw materials due to the continuous discharge of material from the discharge hopper to the same position.

[0015] Preferably, the baffle is located above the turntable, and a brush plate is fixedly connected to the bottom of the baffle. The bottom of the brush plate is in contact with the top of the turntable, and the baffle is the same size and shape as the dividing groove.

[0016] By adopting the above technical solution, and by setting the baffle, when the turntable rotates, the baffle is in a state of being in contact with the surface of the turntable and completely covering the outside of the partition groove. Therefore, when the turntable rotates, the raw material will be blocked by the baffle, so that the raw material always remains in a fixed position.

[0017] Preferably, a side frame is fixedly connected to the outer surface of the baffle, and a second motor is fixedly connected to the outer surface of the side frame. The output end of the second motor passes through the side frame and extends to the other side. A second rotating shaft is fixedly connected to the output end of the second motor. The end face of the second rotating shaft passes through the baffle and extends to the inner side. Eccentric wheels are symmetrically fixedly connected to the outer surface of the second rotating shaft. Both eccentric wheels are located inside the baffle, and the eccentric wheels are positioned to cooperate with the outer frame.

[0018] By adopting the above technical solution, the rotation of the eccentric wheel causes the outer frame and the screening plate to vibrate. Raw materials that meet the particle size requirements will fall through the aperture of the screening plate and the screened raw materials will fall into the corresponding collection box below through the discharge hopper, thus completing the first screening of the raw materials.

[0019] Preferably, the feeding pipe is fixedly connected to the top cover, the feeding pipe is located above the baffle, the top of the storage hopper is fixedly connected to a top plate, the top of the top plate is fixedly connected to a third motor, and the output end of the third motor passes through the top plate and extends to the lower side.

[0020] By adopting the above technical solution, the operation of the third motor can drive the third rotating shaft, rotating plate, stirring rod and scraper to rotate.

[0021] Preferably, the output end of the third motor is fixedly connected to a third rotating shaft, and the lower end face of the third rotating shaft is fixedly connected to a rotating plate. The rotating plate is located near the lower end face of the feeding pipe. A feeding groove is opened on the top of the rotating plate. A fixing ring is fixedly connected to the inner surface of the feeding pipe. A baffle is fixedly connected to the inner surface of the fixing ring. The bottom of the fixing ring is in contact with the top of the rotating plate. The baffle has the same shape as the feeding groove. Multiple stirring rods are evenly fixedly connected to the outer surface of the third rotating shaft. A scraper is fixedly connected to the end face of each of the multiple stirring rods. The outer surface of the scraper is in contact with the inner surface of the feeding pipe.

[0022] By adopting the above technical solution, while the third motor drives the third rotating shaft to rotate for feeding, the third rotating shaft will drive the stirring rod and scraper to rotate as well. The rotation of the stirring rod can stir and disperse the accumulated raw materials, avoiding the accumulation of raw materials that will cause agglomeration and obstruct feeding. The rotation of the scraper against the inner wall of the feeding pipe can scrape off the raw materials attached to the inner wall, avoiding the accumulation of material on the inner wall of the feeding pipe and affecting the feeding efficiency.

[0023] Preferably, the outer surface of the outer shell has multiple slots, and door panels are hinged to the outer surface of the outer shell near the slots. The number of door panels is the same as that of the collection boxes and their positions correspond to each other.

[0024] By adopting the above technical solution, once the raw materials in the collection box are full, the collection box can be removed from the inside of the shell and replaced by opening the door panel at the corresponding position.

[0025] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, when using a raw material screening device to screen spicy seasonings, the screening plates are arranged from the side of the discharge plate, with the filter apertures ranging from fine to coarse, to form different screening levels. After the material is poured into the storage hopper, the device operates automatically through the coordinated operation of the first, second, and third motors. The raw materials are fed in batches, and the coarse materials and fine materials of different particle sizes are graded, screened, and collected. The feeding and collection processes are automated, improving processing efficiency. At the same time, the raw materials are rotated on the plane of the turntable to achieve multi-stage screening. The overall structure of the device is relatively compact and occupies little space. By installing a vibration mechanism consisting of a second motor, a second rotating shaft, and an eccentric wheel at the baffle position, the vibration mechanism can vibrate the outer frame of the current screening position, accurately applying the vibration force to the screening position of the raw materials, improving screening efficiency. Moreover, the range of the vibration force is small, allowing the use of a smaller power motor and saving processing costs.

[0026] 2. In this invention, as the support plate rotates, it drives the caster to move along the slide rail. After passing the inclined surface of the toothed block, the caster will disengage from the toothed block. At this time, the support plate, which is in a lifted state, will fall back to the initial bottom position. As the support plate rotates, the caster repeatedly passes the toothed block position, and the support plate is lifted and falls, which will cause the support plate and the collection box to vibrate. Under the action of vibration, the raw materials accumulated in the collection box are dispersed, and the raw materials can be accumulated more evenly in the collection box, avoiding the continuous discharge of material from the discharge hopper to the same position, which would cause uneven accumulation of raw materials and overflow, resulting in loss.

[0027] 3. In this invention, while the third shaft is driven by the third motor to rotate for material feeding, the third shaft will also drive the stirring rod and scraper to rotate. The rotation of the stirring rod can stir and disperse the accumulated raw materials, preventing them from clumping and causing poor feeding. The scraper rotates against the inner wall of the feeding pipe to scrape off the raw materials adhering to the inner wall, preventing material accumulation on the inner wall of the feeding pipe from affecting feeding efficiency. By cooperating with the rotating plate, fixed ring, and baffle for feeding, the feeding amount can be controlled by controlling the speed or number of rotations of the third motor. At the same time, the feeding chute at the feeding position is rotating when discharging raw materials, which can evenly discharge the raw materials onto the surface of the screening plate, preventing the accumulation of raw materials during discharge and affecting screening efficiency.

The baffle 702 is located above the turntable 501. A brush plate 707 is fixedly connected to the bottom of the baffle 702. The bottom of the brush plate 707 is in contact with the top of the turntable 501. The baffle 702 and the partition groove 502 are the same size and shape. A side frame 703 is fixedly connected to the outer surface of the baffle 702. A second motor 704 is fixedly connected to the outer surface of the side frame 703. The output end of the second motor 704 passes through the side frame 703 and extends to the other side. A second rotating shaft 705 is fixedly connected to the output end of the second motor 704. The end face of the second rotating shaft 705 passes through the baffle 702 and extends to the inside.The outer surface of the second rotating shaft 705 is symmetrically fixedly connected with eccentric wheels 706. Both eccentric wheels 706 are located inside the baffle 702. The eccentric wheels 706 are positioned to cooperate with the outer frame 504. The feed pipe 801 is fixedly connected to the top cover 2. The feed pipe 801 is located above the baffle 702. The top of the storage hopper 802 is fixedly connected with a top plate 803. The top of the top plate 803 is fixedly connected with a third motor 804. The output end of the third motor 804 passes through the top plate 803 and extends to the lower side. The output end of the third motor 804 is fixedly connected with a third rotating shaft 805. A rotating plate 806 is fixedly connected to the lower end face of the material feeding pipe 801. The rotating plate 806 is located near the lower end face of the material feeding pipe 801. A material feeding groove 807 is opened on the top of the rotating plate 806. A fixing ring 808 is fixedly connected to the inner surface of the material feeding pipe 801. A baffle 809 is fixedly connected to the inner surface of the fixing ring 808. The bottom of the fixing ring 808 is in contact with the top of the rotating plate 806. The baffle 809 has the same shape as the material feeding groove 807. Multiple slots are opened on the outer surface of the outer shell 1. Door panels 11 are hinged to the outer surface of the outer shell 1 near the slots. The number of door panels 11 is the same as that of the collection box 604, and their positions correspond to each other.

[0032] In the operation of this invention, when using the raw material screening device to screen spicy seasonings, the third motor 804 drives the rotating plate 806 to rotate. After the rotating plate 806 completes one revolution, the feeding chute 807 returns to its original position below the baffle 809 to stop feeding, discharging the raw material evenly onto the surface of the screening plate 510. Then, the second motor 704 is started to begin screening. After the second motor 704 starts, it drives two eccentric wheels 706 to rotate. The eccentric wheels 706 repeatedly strike the outer frame 504, causing the outer frame 504 and the screening plate to... Vibration occurs at 510. Under vibration, the finest particle size material will fall through the aperture of the screening plate 510 and be discharged into the corresponding collection box 604 below through the discharge hopper 508, completing one screening of the material. Afterward, the second motor 704 stops operating, and the first motor 3 starts, driving the turntable 501 and the support plate 601 to rotate synchronously. The material is blocked by the baffle 702, keeping it in a fixed position. After the first motor 3 completes the rotation of the adjacent separating grooves 502 at intervals, the lower... The screening plate 510 for primary particle size separation moves to the inner side of the baffle 702, and screening is completed by the operation of the second motor 704. The screened material enters the corresponding collection box 604 below through the discharge hopper 508 for collection. Through the continuous operation of the first motor 3 and the second motor 704, the material will pass through all the screening plates 510 to complete the screening of different particle sizes. At this time, the material remaining above the turntable 501 is the coarse material. The first motor 3 controls the turntable 501 and the support plate 601 to continue to rotate, and at this time the discharge plate 509 will rotate. When the material reaches the baffle 702 position, the second motor 704 runs for a short time to vibrate all the material above it into the corresponding collection box 604 below. At this time, all the material above the turntable 501 is cleared. The first motor 3 continues to start, driving the turntable 501 to reset to the initial position. The finest aperture screening plate 510 is inside the baffle 702. At this time, the material is fed above the screening plate 510 by starting the third motor 804. The first motor 3 and the second motor 704 continue to start in coordination to achieve automatic screening and collection of multiple particle sizes for this batch of material.

[0033] Example 2: Figures 2-5 and Figure 8 As shown, multiple casters 602 are evenly fixedly connected to the bottom of the support plate 601, and a slide rail 9 is fixedly connected to the bottom of the outer shell 1. The casters 602 are located inside the slide rail 9, and multiple toothed blocks 10 are evenly fixedly connected to the bottom of the slide rail 9. The toothed blocks 10 have a triangular cross-section.

[0034] In the operation of this invention, as the support plate 601 rotates, it drives the caster 602 to move along the slide rail 9. Due to the arrangement of multiple toothed blocks 10 within the slide rail 9, the caster 602 moves along the inclined surface of the toothed blocks 10 during displacement. At this time, the toothed blocks 10 can lift the caster 602 upwards, meaning the caster 602 can slightly move the support plate 601 and the collection box 604 upwards. The support plate 601 moves upwards through the connection between the sliding sleeve 605 and the connecting sleeve 12. After passing the inclined surface of the toothed blocks 10, the caster 602 disengages from the toothed blocks 10. At this point, the support plate 601 is lifted upwards. The support plate 601 will fall to the initial position at the bottom. As the support plate 601 rotates, the caster wheel 602 repeatedly passes the position of the toothed block 10. The support plate 601 is lifted and dropped, which will cause the support plate 601 and the collection box 604 to vibrate. Under the action of vibration, the raw materials accumulated in the collection box 604 are dispersed, and the raw materials can be accumulated more evenly in the collection box 604. This avoids the discharge bucket 508 continuously feeding material to the same position, which would cause uneven accumulation of raw materials and overflow, resulting in losses. After the raw materials in the collection box 604 are full, the door panel 11 at the corresponding position can be opened to take out the collection box 604 from the inside of the outer shell 1 for replacement.

[0035] Example 3: Figure 11 and Figure 12 As shown, multiple stirring rods 810 are uniformly fixedly connected to the outer surface of the third rotating shaft 805, and scrapers 811 are fixedly connected to the end faces of the multiple stirring rods 810. The outer surface of the scrapers 811 is in contact with the inner surface of the feed pipe 801.

[0036] In the usage steps of this invention, while the third motor 804 drives the third rotating shaft 805 to rotate for feeding, the third rotating shaft 805 will drive the stirring rod 810 and the scraper 811 to rotate as well. The rotation of the stirring rod 810 can stir and disperse the accumulated raw materials, avoiding the accumulation of raw materials and causing agglomeration that would hinder feeding. The scraper 811 rotates against the inner wall of the feeding pipe 801, which can scrape off the raw materials attached to the inner wall, avoiding the accumulation of material on the inner wall of the feeding pipe 801 and affecting the feeding efficiency.

[0037] The overall effect and working principle of the mechanism are as follows: When using the raw material screening device to screen spicy seasonings, the raw material is poured into the storage hopper 802 for screening. The raw material enters the outer shell 1 through the feed pipe 801 for screening. Through the cooperation of the discharge plate 509 and the screening plate 510 above the turntable 501, the screening plates 510 are arranged from the side of the discharge plate 509, with the filter aperture arranged from fine to coarse to form different screening levels. Initially, in the initial position, the feed pipe 801 and the baffle 702 are directly facing the screening plate 510 with the finest aperture below. Screening begins from the screening plate 510 with the finest aperture. The poured raw material will accumulate at the bottom of the feed pipe 801. Because the baffle 809 is located at... Above the rotating plate 806, the baffle 809 blocks the material feeding chute 807, thus blocking the raw material. When feeding begins, the third motor 804 drives the third rotating shaft 805 to rotate. The rotation of the third rotating shaft 805 drives the rotating plate 806 to rotate as well. When the rotating plate 806 rotates, the material feeding chute 807 and the baffle 809 disengage, allowing the raw material to fall from the material feeding chute 807. The material falls above the turntable 501. Since the feeding pipe 801 and the baffle 702 are directly opposite the screening plate 510, the discharged material will be above the screening plate 510, blocked by the baffle 702 on the outside. After one revolution of the rotating plate 806, the material feeding chute 807 returns to its original position below the baffle 809. The feeding process is stopped. The feeding mechanism, consisting of a rotating plate 806, a fixed ring 808, and a baffle 809, allows for feeding control. The feeding amount can be controlled by adjusting the speed or number of rotations of the third motor 804. Simultaneously, the feeding chute 807 rotates while discharging raw materials, ensuring even distribution onto the screening plate 510 surface and preventing material accumulation that could affect screening efficiency. While the third motor 804 drives the third rotating shaft 805 to rotate for feeding, the shaft also drives the stirring rod 810 and scraper 811 to rotate. The stirring rod 810 disperses any accumulated raw materials, preventing clumping and ensuring smooth feeding. The scraper 811 adheres to the feeding pipe. The rotation of the inner wall of feed pipe 801 scrapes off the raw material adhering to the inner wall, preventing material accumulation on the inner wall of feed pipe 801 from affecting feeding efficiency. After the raw material is fed and positioned above the screening plate 510, the second motor 704 is started to begin screening. The second motor 704 drives the second rotating shaft 705 to rotate, which in turn drives two eccentric wheels 706 to rotate. The initial position of the eccentric wheels 706 is with the eccentric head facing upwards. As the eccentric wheels 706 rotate, the upper eccentric head rotates downwards, applying downward pressure to the outer frame 504. When the outer frame 504 is pressed down, it compresses the spring 506, causing it to contract. Afterwards, the eccentric wheels 706 rotate back to their initial position, and the outer frame 504 loses pressure.The outer frame 504 is moved upward and reset by the rebound force of the spring 506. During its vertical movement, the outer frame 504 slides along the limiting groove 503 via the connection of the limiting block 505, thus limiting the displacement trajectory of the outer frame 504 and its initial position. The rebound force of the spring 506 presses the limiting block 505 against the top position within the limiting groove 503, ensuring that under normal conditions, the discharge plate 509 and each screening plate 510 are flush with the turntable 501, preventing material leakage during transfer. As the second motor 704 continues to operate, the eccentric wheel 706 repeatedly strikes the outer frame 504, causing vibration in the outer frame 504 and the screening plates 510. Under vibration conditions, the finest particles are... The raw material of the required diameter will fall through the aperture of the screening plate 510 and be discharged into the corresponding collection box 604 below through the discharge hopper 508, completing the first screening of the raw material. By installing a vibration mechanism consisting of a second motor 704, a second rotating shaft 705, and an eccentric wheel 706 at the baffle 702 position, the vibration mechanism can vibrate the outer frame 504 at the current screening position, accurately applying the vibration force to the screening position of the raw material, improving screening efficiency. Moreover, the vibration force has a small range, allowing the use of a smaller power motor and saving processing costs. After the second motor 704 stops running, it still controls the eccentric wheel 706 to return to the initial position to avoid affecting the outer frame 504. When the material is flush with the turntable 501, the first motor 3 is started to rotate the material, performing a larger particle size screening. After the first motor 3 starts running, it drives the first rotating shaft 4 to rotate. The rotation of the first rotating shaft 4 drives the turntable 501 to rotate. The first rotating shaft 4 can drive the support plate 601 to rotate through the connection of the connecting sleeve 12 and the sliding sleeve 605. The connecting sleeve 12 and the sliding sleeve 605 are connected by a sliding block, which can realize a sliding connection relationship for the up and down stroke. Therefore, the support plate 601 can slide up and down along the first rotating shaft 4 and rotate with the drive of the first rotating shaft 4. That is, when the first motor 3 is running, the turntable 501 and the support plate 601 can rotate synchronously. When the turntable 501 rotates, since the material is on the turntable 501, the material is flush with the turntable 501. Above 01, the turntable 501 moves the raw material accordingly. However, because the baffle 702 is in a state of being in contact with the surface of the turntable 501 and completely covering the outside of the separating groove 502, the raw material is blocked by the baffle 702 when the turntable 501 rotates, keeping the raw material in a fixed position. When the turntable 501 rotates, the dense and fine bristles of the brush plate 707 at the bottom of the baffle 702 can adhere well to the surface of the screening plate 510 and the turntable 501, leaving the raw material behind and preventing it from moving out of the gaps and causing loss. After the first motor 3 completes the rotation of the adjacent separating groove 502 at interval angles, the screening plate 510 for the next level of particle size moves to the inner position of the baffle 702, and the screening is completed by the operation of the second motor 704.The screened raw material enters the corresponding collection box 604 below through the discharge hopper 508 for collection. Then, the first motor 3 and the second motor 704 work together to drive the next-stage screening plate 510 to move to the baffle 702 for further screening. Through the continuous operation of the first motor 3 and the second motor 704, the raw material passes through all the screening plates 510 to complete the screening of different particle sizes, and the screened raw material enters the corresponding collection box 604 for collection. The collection boxes 604 corresponding to the screening plates 510 collect fine materials of different particle sizes. At this time, the raw material remaining above the turntable 501 is the coarse material. The first motor 3 controls the turntable 501 and the support plate 601 to continue rotating. At this time, the discharge plate 509 rotates to the baffle 702 position. The surface of the discharge plate 509 has large openings, and the second motor 704 can vibrate all the raw material above it to the corresponding baffle 702 in a short time. Inside the collection box 604, all the raw materials above the turntable 501 are emptied. The first motor 3 continues to start, driving the turntable 501 back to its initial position. The finest aperture screening plate 510 is inside the baffle 702. At this time, the third motor 804 starts and feeds the material above the screening plate 510. The first motor 3 and the second motor 704 continue to work together to automatically screen and collect the batch of raw materials for multiple particle sizes. That is, when the raw material screening device is used to screen spicy seasonings, after the material is poured into the storage hopper 802, it can automatically operate through the cooperation of the first motor 3, the second motor 704 and the third motor 804, feeding the raw materials in batches and classifying and collecting coarse materials and fine materials of different particle sizes. The feeding and discharging collection process is automated, improving processing efficiency. At the same time, the raw materials are rotated on the plane of the turntable 501 to achieve multi-stage screening. The overall structure of the device is relatively compact and occupies little space.
