Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, and more specifically, to a feeding device for processing dried chili peppers. Background Technology

[0002] Dried chili peppers are a condiment / raw material made from fresh chili peppers through dehydration and drying. The core purpose of using feeding equipment during processing is to improve efficiency, ensure uniformity, and reduce costs. Essentially, it is a product of removing moisture from fresh chili peppers (such as bird's eye chili, Erjingtiao chili, etc.) through natural sun-drying or mechanical drying. As a core ingredient in catering seasoning and food processing, the efficiency, uniformity, and purity of the feeding operation in the batch processing (such as crushing, cutting, and capsaicin extraction) directly determine the subsequent processing quality and production costs. In existing technologies, manual feeding relies on human handling and feeding, which is not only inefficient and labor-intensive, but also difficult to precisely control the amount of material fed, easily resulting in inconsistent amounts. This leads to poor consistency in subsequent processing indicators such as crushing particle size and cutting length, affecting product quality. Traditional feeding equipment lacks a targeted impurity removal structure, making it impossible to simultaneously remove impurities such as dust, fragments, and shriveled debris adhering to dried chilies during drying and storage. This requires additional impurity removal processes, increasing production steps and costs. Furthermore, the screening of defective products is disconnected from the feeding process; moldy, broken, or excessively small dried chilies are difficult to remove in time during feeding, and mixing with qualified materials reduces the purity of the final product. Some automated feeding equipment has complex drive structures, insufficient operational stability, and poor feeding continuity, making it difficult to adapt to the high-efficiency operation requirements of large-scale production lines. Therefore, a dried chili processing feeding device is provided that integrates automated quantitative feeding, synchronous impurity removal, and defective product rejection. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a feeding device for processing dried chili peppers, which aims to solve the problems mentioned in the background art.

[0004] The present invention provides the following technical solution: a feeding device for processing dried chili peppers, including a base, on which a conveying component is provided; The conveying assembly includes a reinforcing frame disposed on the top of the base, a gathering hopper disposed at the bottom of the reinforcing frame, a limiting plate disposed at one end of the reinforcing frame, and a feeding fan rotatably connected to the limiting plate. The feeding fan is fan-shaped and has a metering groove. The bottom of the gathering hopper has a through-hole frame, and the feeding fan is located inside the through-hole so that the feeding fan can rotate inside the through-hole to take material from the gathering hopper. One end of the limiting plate is embedded with a feeding plate, which is connected to the metering tank and is used to transport the material in the metering tank to the feeding plate. The outer side of the feeding fan and one side of the inner wall of the frame opening are respectively provided with teeth, and two of the teeth are in contact with each other, so that the amplitude generated by the rotation of the feeding fan and the contact of each tooth is transmitted to the feeding fan to vibrate and screen the material in the quantitative tank, so that the surface impurities are removed.

[0005] Optionally, in one possible implementation, a mounting base is provided on one side of the bottom of the reinforcing frame, and a limiting shaft is rotatably connected to the mounting base. A first linkage rod is provided at one end of the limiting shaft, and a second linkage rod is provided at the other end of the limiting shaft. A sliding groove is provided through the surface of the feeding fan, and a sliding rod is provided at one end of the second linkage rod. The sliding rod extends into the sliding groove and is slidably connected to the sliding groove, so that when the second linkage rod drives the sliding rod to rotate along the axial direction of the limiting shaft, the sliding rod rubs against the sliding groove and actuates the feeding fan to rotate. A hydraulic rod is provided on one side of the mounting base, and the output end of the hydraulic rod extends to one end of the first linkage rod and is hinged to the first linkage rod. The hydraulic rod is also hinged to the base, so that the output end of the hydraulic rod extends to drive the first linkage rod to rotate the limiting shaft. Optionally, in one possible implementation, the feeding fan is hollow, and a discharge port is provided on one side of the bottom of the feeding fan. A filter screen is embedded in the bottom of the inner wall of the metering trough so that airflow enters the feeding fan through the metering trough for removing impurities from the material. An exhaust fan is connected to the discharge port through a flange. An exhaust fan is provided at one end of the hose. The exhaust fan is bolted to the base, and the hose is connected to the input end of the exhaust fan. A filter element is provided at the connection between the discharge port and the hose. Optionally, in one possible implementation, the horizontal plate is located at the top of the feeding pipe, and a vision sensor for detection is provided on the horizontal plate. The vision sensor is located on the bottom side of the feeding plate to perform visual inspection on the material conveyed by the feeding plate for rejecting defective products. A sealing plate is slidably connected to the horizontal plate. The sealing plate is located at the top of the feeding pipe for sealing the feeding pipe. A second electric push rod for driving the displacement of the sealing plate is provided at one end of the horizontal plate, and a first electric push rod for driving the displacement of the horizontal plate is provided at one end of the frame.

[0006] The technical effects and advantages of this invention are as follows: This invention first achieves automated quantitative feeding, significantly improving feeding efficiency and uniformity. A hydraulic rod drives a linkage assembly to rotate the feeding fan. The feeding fan's quantitative trough precisely scoops dried chilies from the gathering hopper. Combined with the matching design of the frame opening and the feeding fan, it ensures consistent feeding volume per batch, completely solving the problems of uneven feeding and low efficiency caused by manual feeding. Simultaneously, the hydraulic drive structure operates stably, and the feeding fan speed can be controlled by adjusting the extension and retraction frequency of the hydraulic rod, adapting to the feeding rhythm of different production lines and meeting the needs of large-scale batch processing.

[0007] This invention employs a dual impurity removal design of vibrating screen and airflow, significantly improving material purity. The teeth on the outer side of the feeding fan mesh with the inner wall of the frame, and the high-frequency amplitude generated during rotation causes impurities on the surface of dried chilies in the metering trough to fall off, achieving preliminary vibrating screen impurity removal. Combined with the airflow impurity removal system consisting of the hollow structure of the feeding fan, the filter screen, and the exhaust fan, the negative pressure airflow can quickly carry away the fallen fine impurities, which are discharged through the discharge port and hose. The dual impurity removal mechanism eliminates the need for additional impurity removal processes, completing impurity cleaning simultaneously during the feeding process, reducing production time and costs.

[0008] Based on the feeding process, this invention uses a visual sensor to monitor the material conveyed by the feeding plate in real time. Through image recognition technology, it quickly identifies defective products such as mold and breakage, and simultaneously triggers an electric push rod to drive a sealing plate to temporarily block the feeding pipe, causing defective products to fall into the waste area. This prevents qualified materials from being mixed in, ensures the purity and quality of subsequent processed products, and reduces resource waste.

[0009] The inverted conical structure of the gathering bucket of this invention can prevent material from scattering. The inclined design of the feeding plate uses gravity to assist in material conveying, reducing power consumption. Combined with wear-resistant teeth, slide bars and other components, it can extend the service life of the equipment and reduce long-term operating costs.

[0010] In summary, this invention, through its integrated design of automated quantitative feeding, dual impurity removal, and precise rejection of defective products, not only solves the core problems of low feeding efficiency and uneven feeding in traditional methods, but also simultaneously improves material purity and product quality. Furthermore, its stable structure and strong adaptability significantly reduce the labor intensity and overall cost of production, providing an efficient and reliable feeding solution for the large-scale processing of dried chili peppers.

[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] This embodiment discloses a feeding device for dried chili processing, aiming to solve the problems of low efficiency, uneven feeding, impurities, and contamination of defective products in existing dried chili processing manual feeding, and to achieve automated, quantitative, and impurity removal integrated feeding operations: like Figure 1 , Figure 2 As shown, it includes a base 1, which serves as an overall support structure. A conveying component is fixedly installed on the top, and a frame 18 is welded to one end. The conveying component consists of a reinforcing frame 2, a gathering bucket 3, a limiting plate 4, and a feeding fan 5. A material discharge detection component is mounted on the frame 18. A drive mechanism and a cleaning mechanism are also installed on the base 1. All components work together to realize the entire process of material feeding, cleaning, and detection.

[0022] like Figure 3 , Figure 4 , Figure 5 As shown, the bottom of the reinforcing frame 2 is integrally formed with a gathering bucket 3, which has an inverted cone shape and is used to centrally stack the dried chilies to be processed to prevent the material from scattering. One end of the reinforcing frame 2 is fixed with a limiting plate 4 by bolts. The inner side of the limiting plate 4 is rotatably connected to a feeding fan 5, which is set as a fan-shaped structure. A quantitative groove 25 is opened on its surface. The volume of the quantitative groove 25 is adapted to the feeding requirements of a single processing, so as to realize quantitative material dispensing.

[0023] The bottom of the collecting hopper 3 has a through-hole 6 that fits the feeding fan 5. The feeding fan 5 is embedded in the through-hole 6, and the outer edge of the feeding fan 5 and one side of the inner wall of the through-hole 6 are integrally formed with teeth 8. The two sets of teeth 8 are in contact with each other in a raised shape and can be made of hard plastic or elastic rubber. When the feeding fan 5 rotates, the two sets of teeth 8 rub and collide with each other to generate high-frequency amplitude. This amplitude is transmitted to the metering groove 25 of the feeding fan 5, causing the dust, debris and other impurities attached to the surface of the dried chili peppers in the groove to fall off during the vibration, completing the initial vibration screening and impurity removal.

[0024] One end of the limiting plate 4 is embedded with the feeding plate 7, which is inclined and its upper end is connected to the discharge end of the quantitative trough 25. When the feeding fan 5 rotates to align the quantitative trough 25 with the feeding plate 7, the quantitative amount of dried chili peppers in the trough slides down to the feeding plate 7 under the action of gravity and is conveyed along the feeding plate 7 towards the frame 18.

[0025] like Figure 6 As shown, a mounting base 9 is provided on one side of the bottom of the reinforcing frame 2. The mounting base 9 is fixed to the base 1 by bolts. A limiting shaft is rotatably connected to the mounting base 9. A first linkage rod 10 is welded to one end of the limiting shaft, and a second linkage rod 11 is welded to the other end. A sliding groove 12 is provided through the surface of the feeding fan 5. A sliding rod 13 is welded to the end of the second linkage rod 11 away from the limiting shaft. The sliding rod 13 extends into the sliding groove 12 and slides in cooperation with the sliding groove 12.

[0026] A hydraulic rod 14 is provided on one side of the mounting base 9. The fixed end of the hydraulic rod 14 is hinged to the base 1, and the output end is hinged to the end of the first linkage rod 10 away from the limiting shaft. When the output end of the hydraulic rod 14 extends or retracts, it drives the first linkage rod 10 to reciprocate around the limiting shaft, thereby driving the limiting shaft to rotate. The limiting shaft synchronously drives the second linkage rod 11 to swing, causing the slide rod 13 to slide along an arc trajectory in the slide groove 12. Through the frictional force between the slide rod 13 and the slide groove 12, the feeding fan 5 is propelled to rotate at a uniform speed in the frame opening 6, realizing continuous quantitative material feeding.

[0027] like Figure 3 , Figure 6As shown, the feeding fan 5 is a hollow structure with a discharge port 15 on one side of its bottom. A stainless steel filter screen is embedded in the bottom of the inner wall of the metering tank 25. The pore size of the filter screen is smaller than that of the dried chili pepper particles to ensure that the material does not leak. A hose 17 is fixedly connected to the discharge port 15 by a flange. The other end of the hose 17 is connected to the input end of the exhaust fan 16. The exhaust fan 16 is installed on the base 1 by bolts. A filter element is provided at the connection between the discharge port 15 and the hose 17 to prevent dried chili pepper fragments from being lost with the airflow.

[0028] When the exhaust fan 16 is started, a negative pressure is formed inside the feeding fan 5. The airflow enters from the opening end of the metering trough 25, passes through the filter screen, and carries the impurities, dust, and fragments that fall off the vibrating screen. The airflow is then discharged by the exhaust fan 16 through the discharge port 15 and the hose 17, thus achieving secondary airflow to remove impurities and improve the purity of the dried chili peppers.

[0029] like Figure 7 As shown, a feeding pipe 19 is embedded in the top of the frame 18. The input end of the feeding pipe 19 corresponds to the output end of the feeding plate 7 and is used to transport qualified materials to subsequent processing equipment. A horizontal plate 20 is slidably connected to the top of the frame 18 via a slide rail. The horizontal plate 20 is located directly above the feeding pipe 19, and a vision sensor 24 is fixedly installed on the horizontal plate 20 via a bracket. The detection end of the vision sensor 24 faces the bottom output end of the feeding plate 7 and is used to take real-time pictures of the dried chili peppers conveyed by the feeding plate 7. The image recognition technology is used to determine whether the material is defective, such as moldy, broken, or too small.

[0030] A sealing plate 21 is slidably connected to the horizontal plate 20 via a slide rail. The size of the sealing plate 21 is adapted to the opening of the feed pipe 19 and is used to selectively seal the feed pipe 19. A second electric push rod 23 is bolted to one end of the horizontal plate 20. The output end of the second electric push rod 23 is welded to the sealing plate 21. A first electric push rod 22 is bolted to one end of the frame 18. The output end of the first electric push rod 22 is welded to the horizontal plate 20.

[0031] When the vision sensor 24 detects a defective product, it sends a signal to the controller. The controller then controls the second electric push rod 23 to extend rapidly, pushing the sealing plate 21 to the opening of the discharge pipe 19 to temporarily block the discharge pipe 19. At the same time, the controller controls the first electric push rod 22 to push the horizontal plate 20, which in turn moves the vision sensor 24 synchronously. After the defective product falls from the end of the discharge plate 7 into the waste collection area, the second electric push rod 23 retracts, the sealing plate 21 resets, and the discharge pipe 19 is unblocked, ensuring that defective products do not mix with qualified materials.

[0032] The specific working principle is as follows: the dried chili peppers to be processed are poured into the gathering hopper 3, and the dried chili peppers are concentrated and gathered towards the frame opening 6 under the action of the conical structure of the gathering hopper 3. Start the hydraulic rod 14. The hydraulic rod 14 drives the feeding fan 5 to rotate in the frame opening 6 through the linkage rod. When the quantitative groove 25 of the feeding fan 5 rotates to the bottom of the gathering hopper 3, it scoops up a quantitative amount of dried chili peppers. During the rotation, the amplitude generated by the collision of the teeth 8 causes impurities on the surface of the material to fall off. Airflow impurity removal: Simultaneously start the exhaust fan 16, and the airflow in the metering tank 25 carries the fallen impurities through the filter screen, the impurity discharge port 15, and the hose 17 to complete the deep impurity removal; When the quantitative trough 25 rotates to align with the feeding plate 7, the cleaned dried chili peppers slide down to the feeding plate 7 and are conveyed along the feeding plate 7 to the frame 18. The visual sensor 24 detects the material quality in real time. If the material is qualified, the sealing plate 21 remains open, and the dried chili peppers enter the subsequent processing equipment through the feeding pipe 19; if defective products are detected, the sealing plate 21 temporarily blocks the feeding pipe 19, and the defective products fall into the waste area. Then the sealing plate 21 is reset, and the equipment continues to operate.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
