Description

Technical Field

[0001] This utility model relates to the field of Sichuan pepper processing technology, and in particular to an anti-caking feeding device for Sichuan pepper protein powder. Background Technology

[0002] Sichuan pepper is the dried pericarp of a plant belonging to the genus Zanthoxylum in the Rutaceae family. It is one of the most essential and iconic spices in cooking, belonging to the "spice" category. Sichuan pepper protein powder is a product of modern food processing technology. It is a plant-based functional food ingredient and is not made directly from ground Sichuan pepper. Instead, it is an extract that has undergone extensive processing. It is a protein-rich powder product obtained from Sichuan pepper seeds through processes such as defatting, separation, extraction, and drying.

[0003] A search revealed that Chinese patent CN212981454U discloses a screw feeder. This patent addresses commonly used screw feeders, which employ standard screws with equal diameter blades and identical pitch between adjacent blades. When the screw rotates, due to the screw structure, the flowability of wood powder, and the angle of repose, the wood powder initially propels from the tail of the hopper. The wood powder near the tail falls, forming an inverted cone-shaped hole resembling a funnel, while the remaining portion is filled with wood powder. This leaves the screw shaft and blades at the tail of the hopper exposed. The wood powder covering the screw blades easily forms "arches" or "bridges," affecting metering accuracy. Therefore, a standard screw feeder with equal diameter and pitch is used for wood powder metering. While its metering accuracy is low and affects product quality, this method ensures the material is evenly pushed out, avoiding "arching" or "bridging" phenomena. Precise metering ensures product quality and can be extended to metering powdery materials in other production processes, demonstrating strong applicability.

[0004] In the production and processing of Sichuan pepper protein powder, because it is rich in protein and contains a small amount of residual oil, it is very easy to absorb moisture and clump together, forming hard lumps of varying sizes. This clumping phenomenon is very likely to occur during storage and transportation, which not only affects the uniformity and continuity of feeding, but also has an adverse impact on subsequent production processes and product quality. Traditional common powder feeding devices mostly use screw conveyors, but screw conveyors often lack effective anti-caking and screening functions, and the spiral shape is not easy to break up the clumps of powder, making it difficult to meet the actual needs of Sichuan pepper protein powder production.

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-caking feeding device for Sichuan pepper protein powder.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-caking feeding device for Sichuan pepper protein powder, comprising a feeding shell, a feed pipe fixedly connected to the upper surface of the feeding shell, a screening frame provided below the feeding shell, a discharge shell provided below the screening frame, two U-shaped frames fixedly connected to both sides of the discharge shell and the feeding shell, and a screening component for crushing and screening Sichuan pepper protein powder provided inside the screening frame; The sieving assembly includes two triangular blocks that guide the pepper protein powder.

A protrusion is fixedly connected to one end of the square rod.

[0009] As a further description of the above technical solution: The inner wall of the mounting shell has multiple circular slots on one side. A spring is fixedly connected inside the circular slot. A cylindrical block is fixedly connected to one end of the spring. The cylindrical block is slidably connected inside the circular slot. Multiple cylindrical blocks are fixedly connected to one side of the side plate.

[0010] As a further description of the above technical solution: The screening frame is provided with a release assembly on its exterior to release the screening frame from between the feed shell and the discharge shell. The release assembly includes two connecting frames, which are respectively fixedly connected to both sides of the screening frame.

[0011] As a further description of the above technical solution: A stepper motor is fixedly installed inside the bracket, and a screw is fixedly connected to the output end of the stepper motor. The screw is threaded into the inside of the square rod.

[0012] As a further description of the above technical solution: Both sides of the feeding shell are fixedly connected to limit frames.

[0014] This utility model has the following beneficial effects: 1. This utility model, through the setting of the screening component, uses a main shaft and stirring rod driven by a variable speed motor for primary stirring and crushing, and simultaneously drives the square rod and its end cutting frame and cutting blade for secondary precision cutting. This facilitates the crushing of powder lumps of different hardness that are difficult to pass through the screen. During the crushing process, the continuous pushing of the screen by the semi-circular block and the action of the return spring cause the screen to generate high-frequency micro-amplitude vibration, creating linkage. There is no need to use a vibration motor to make the screen vibrate separately, which helps to improve the continuity and efficiency of screening. At the same time, the side scraper can easily scrape the inner wall of the cylindrical feed shell, reducing material residue.

[0015] 2. With the help of the push spring, the entire screening module can be quickly detached from the feed shell and the discharge shell without tools by setting up the detachment component. It is parallel to the feed shell and the screening frame, so that the easily clogged screen can be exposed to the operator's field of vision, thereby clearing the screen mesh and improving the convenience of screen maintenance.

[0019] As attached Figure 1-10 As shown, one embodiment of this utility model is provided: an anti-caking feeding device for Sichuan pepper protein powder, including a feeding shell 1 with an internal cylindrical cavity, a feed pipe 2 fixedly connected to its upper surface, the feed pipe 2 being used to stably transport Sichuan pepper protein powder into the feeding shell 1, a screening frame 3 being provided below the feeding shell 1, the screening frame 3 being used to screen the incoming Sichuan pepper protein powder, an outlet shell 4 being provided below the screening frame 3, the outlet shell 4 being used to collect and discharge qualified Sichuan pepper protein powder after screening, and two U-shaped frames 5 being fixedly connected on both sides between the outlet shell 4 and the feeding shell 1, the U-shaped frames 5 serving to stably connect the outlet shell 4 and the feeding shell 1; The sieving assembly includes two triangular blocks 6 that guide the pepper protein powder. The two triangular blocks 6 are fixedly connected to the inner walls of the sieving frame 3 on both sides. Their inclined surfaces can guide the pepper protein powder to flow towards the central area of ​​the sieving frame 3, reducing accumulation. The lower surface of the triangular blocks 6 is fixedly connected to a mounting shell 7 for accommodating the side plate 8.

[0020] As attached Figure 4As shown, a side plate 8 is slidably connected inside the mounting shell 7. The side plate 8 can slide within the mounting shell 7 to a certain extent. A screen 9 is fixedly connected between the two side plates 8 for screening the pepper protein powder. Only powder with a particle size smaller than the aperture of the screen 9 can pass through. A semi-circular block 10 is fixedly connected near the center of the upper surface of the screen 9. The semi-circular block 10 cooperates with the protrusion 20.

[0021] As attached Figure 7 As shown, a variable speed motor 11 is fixedly installed on the upper surface of the feed shell 1. The variable speed motor 11 serves as the power source for the entire device and can adjust its speed according to actual needs.

A main shaft 14 with an internal structure is fixedly connected to the lower surface of the bracket 12. The main shaft 14 is hollow inside, with a square rod-shaped cavity to accommodate square rods 17. Multiple stirring rods 15 are fixedly connected to the outside of the main shaft 14. During rotation, the stirring rods 15 can stir the pepper protein powder in the feed shell 1, reducing its initial accumulation and clumping. One end of one of the stirring rods 15 is fixedly connected to a side scraper.

[0023] As attached Figure 3 As shown, the screen frame 3 is provided with an ejection assembly on its exterior to eject the screen frame 3 from between the feed shell 1 and the discharge shell 4. The ejection assembly includes two connecting frames 24, which are fixedly connected to both sides of the screen frame 3. The connecting frames 24 have round holes inside, which are used for sliding connection to the exterior of the limiting frame 25.

[0024] As attached Figure 8As shown, a stepper motor 13 is fixedly installed inside the bracket 12. The output end of the stepper motor 13 is fixedly connected to a screw 21, which facilitates driving the screw 21 to rotate. The screw 21 is threadedly connected inside the square rod 17. Correspondingly, the square rod 17 has a threaded groove with the same height as the screw 21 and matching threads.

[0025] As attached Figure 10 As shown, limit frames 25 are fixedly connected to both sides of the feed housing 1. A push spring 26 is fixedly connected to the outer side of the limit frame 25. One end of the push spring 26 is fixedly connected to one side of the connecting frame 24. Two square slots 27 are formed on the upper surface of the limit frame 25. A magnet 28 is fixedly connected to the bottom of the inner wall of the square slot 27. As attached Figure 3 As shown, the connecting frame 24 has an internal mounting groove for mounting the I-beam 29. The I-beam 29 is slidably connected inside the mounting groove. The I-beam 29 consists of a bottom square iron block, a middle cylindrical rod, and a top square block. A second spring 30 is fixedly connected to one side of the middle part of the I-beam 29. The second spring 30 is fixedly connected to the upper surface of the square iron block and sleeved on the outside of the cylindrical rod. The second spring 30 is fixedly connected to the top of the inner wall of the mounting groove. The I-beam 29 is made of iron, which facilitates adsorption with the magnet 28. The I-beam 29 and the square groove 27 are engaged.

[0026] As attached Figure 1 As shown, two blocks 31 are fixedly connected to one side of the feed housing 1 to block the movement of the screening frame 3.

[0027] Working principle: First, the feed pipe 2 is connected to the pipe of the external pepper protein powder storage tank, and the discharge pipe on the discharge shell 4 is connected to the pipe of the device to be processed pepper protein powder. After the pepper protein powder enters the feed shell 1 through the feed pipe 2, it falls on the two triangular blocks 6 and the screen 9. Then the device is started. The variable speed motor 11 drives the main shaft 14 and its multiple stirring rods 15 to rotate through the bracket 12, which initially disperses and crushes the falling powder. At the same time, the main shaft 14 drives multiple cutting frames 18 and their internal cutting blades 19 to rotate through the square rod 17, thereby precisely cutting the still large blocks after initial crushing, forming a two-stage crushing mechanism.

[0028] The crushed powder falls onto the screen 9 for sieving. The qualified fine powder passes through the screen 9 and enters the discharge shell 4 below, and is eventually discharged by the discharge pipe of the discharge shell 4. During this process, as the main shaft 14 rotates, it drives the square rod 17 to rotate, which in turn drives the protrusion 20 to periodically move and push the semi-circular block 10, causing the semi-circular block 10 to move the screen 9. When the screen 9 moves, the screen 9 and the side plates 8 on both sides slide in the mounting shell 7 and squeeze multiple cylindrical blocks 23 on one side. The cylindrical blocks 23 squeeze the spring 22, causing the spring 22 to store force. When the protrusion 20 leaves the semi-circular block 10 and no longer squeezes it, the multiple squeezed springs 22 push the cylindrical block 23, causing the cylindrical block 23 to push the side plate 8, which in turn drives the screen 9 to move, causing the other side plate 8 to be squeezed. This cycle repeats, causing the screen 9 to generate continuous radial high-frequency vibration, which facilitates the sieving of materials and keeps the sieving smooth.

[0029] When it is necessary to clean the screen 9, first drive the stepper motor 13 so that its output end drives the screw 21 to rotate. Under the action of the thread groove, the square rod 17 will move upward in the internal cavity of the main shaft 14, which will in turn drive multiple cutting frames 18 to move upward, so as not to obstruct the movement and release of the screening frame 3. Then, the operator can pull the I-beams 29 on both sides upwards with both hands. The I-beams 29 overcome the attraction of the magnet 28 and the slight resistance of the spring 30, and move out of the square groove 27 of the limiting frame 25 and into the installation groove, so that the connecting frame 24 is released from the limit. After releasing the hand, the connecting frame 24 will slide outside the limiting frame 25 under the pushing force of the pushing springs 26 on both sides, driving the screening frame 3 to disengage from between the feeding shell 1 and the discharge shell 4, so that the screen 9 is exposed to the operator's line of sight. At this time, the push... When the moving spring 26 is in the unfolded state, the I-beam block 29 will be inserted into another square groove 27 on the limiting frame 25 and attracted to the magnet 28. After that, the operator only needs to use tools to clean the exposed screen 9. During installation, lift the I-beam block 29 and push it into the screening frame 3 in the opposite direction. When the screening frame 3 is squeezed by the pushing spring 26 and blocked by the stop block 31, the I-beam block 29 will automatically be inserted into the square groove 27 near the end of the pushing spring 26 under the action of the second spring 30 and will be attracted and fixed by the magnet 28, thus completing the installation.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
