Description

Technical Field

[0001] The present invention relates to the technical field of nut processing. More specifically, the present invention relates to a feeding device for nut processing and a feeding method thereof. Background Art

[0002] Nuts, as the name implies, are a type of fruit with a hard outer shell and usually in a closed state. Inside, they enclose edible parts, mainly seeds or kernels. These seeds or kernels not only have a rich taste but also extremely high nutritional value. They are rich in protein, fat, minerals, and various vitamins, which bring many benefits to human health. For example, protein helps with muscle growth and repair, fat provides energy and maintains cell structure, minerals such as magnesium and potassium are crucial for bone health, and vitamins such as vitamin E and vitamin B groups contribute to antioxidant and metabolic functions. In the process of nut processing, the design of the feeding device is particularly crucial. The feeding device is the front-end part of the entire processing production line and is responsible for evenly and efficiently feeding nuts into subsequent processing steps. A well-designed feeding device can significantly improve processing efficiency, reduce breakage and waste of nuts during transportation, and thus ensure the quality of the final product.

[0003] According to the patent document: CN118618796A, a feeding device for nut processing and a feeding method thereof are disclosed, including a transmission mechanism. The transmission mechanism further includes a bottom plate. The top of the bottom plate is fixedly connected with a first support frame. Before using this device, install the device at the required position, put the walnuts to be transmitted into the inner part of the feeding pipe, and connect the power supply of the power motor. As the power motor drives the second transmission column to rotate, the second transmission column drives the transmission belt to rotate synchronously, so that the friction wheel installed on the outer wall of the transmission belt contacts the friction plate. At this time, the frictional force generated by the contact between the friction wheel and the friction plate will force the sliding rod to move along the inner wall of the sliding track towards the mounting frame, forcing the rotating plate to form a shape as shown in Figure 5 shown, so that a receiving groove is formed between the rotating plate and the transmission belt. At this time, the walnuts on the inner wall of the feeding pipe enter the receiving groove through the rotating baffle.

[0004] When nuts need to be transported, since nuts usually vary in size, some smaller nuts may not be fully closed or have irregular shapes. This may cause them to become blocked or stuck in the crusher when entering other processes after transportation, thus affecting the smoothness and efficiency of the entire production line. In addition, the kernels inside smaller nuts may not be fully developed, resulting in uneven quality of the kernels, which in turn affects the taste and nutritional value of the final product, and affects the quality and taste of the final product. Summary of the Invention

[0005] To overcome the above-mentioned defects of the prior art, the present invention provides a feeding device and a feeding method for nut processing. The technical problem to be solved by the present invention is that since nuts are usually of different sizes, some smaller nuts may usually be incompletely closed or irregular in shape, which may cause them to be blocked or stuck in the crusher when entering other processes after conveying, thus affecting the smoothness and efficiency of the entire production line. In addition, the kernels inside smaller nuts may not be fully developed, resulting in uneven quality of the kernels, which in turn affects the taste and nutritional value of the final product, and affects the quality and taste of the final product.

[0015] In addition, the present invention also relates to a feeding device for nut processing and its feeding method, including the following steps: Step 1: Nuts are poured into the storage bin and enter the material distribution and blanking assembly through the blanking funnel of the storage bin. The motor is started, and the turntable and the second turntable rotate, driving the columnar horizontal rotating rod, the roller and the baffle to rotate synchronously. The baffle intermittently guides the nuts to the blanking bin, preventing blockage and ensuring that the nuts enter the next stage evenly and orderly. Step 2: The nuts fall from the feeding bin onto the screening and feeding plate. The fourth turntable is driven by the second crawler, causing the second transmission shaft, the transmission shaft, and the third crawler to rotate. The third crawler drives the second columnar transverse rotating rod and the rhombic abutting block to rotate. The abutting block impacts the disc, causing the inverted L-shaped vibrating block to vibrate within the L-shaped side rod. As a result, the sieve net vibrates, screening the nuts. The small nuts pass through the sieve net onto the defective material discharging plate, while the large nuts remain on the screening and feeding plate and slide towards the transmission mechanism for processing; Step 3: The relatively small nuts after screening slide down along the defective material discharging inclined plate into the leftmost receiving box of the defective material conveying mechanism. When this receiving box is full, the hydraulic push rod is activated, pushing the receiving box backward and sliding it onto the longitudinal conveyor table, and then being conveyed to the next processing link through the longitudinal conveyor table; Step 4: The spring compresses to prepare for the reset of the push plate. After the leftmost receiving box is pushed away, the spring releases energy, pushing the push plate to move leftward, and then pushing the remaining receiving boxes to slide leftward in sequence, moving the next receiving box to the leftmost position to continue receiving the sliding smaller nuts. This process realizes the automatic collection and continuous conveyance of the smaller nuts, significantly improving the processing efficiency and automation level.

[0016] The beneficial effects of the present invention are as follows: By providing a feeding mechanism, a transmission mechanism, and a defective material conveying mechanism, the present invention realizes the automation and high efficiency of the nut processing process. Through the exquisitely designed feeding device and its feeding method, it not only ensures that the nuts can enter the next process evenly and orderly, effectively preventing the blockage of the feeding port caused by nut accumulation, but also effectively screens the nuts through the screening mechanism, timely separating the nuts with relatively small volume or unqualified quality, avoiding unqualified products from entering the subsequent processing links, thereby greatly improving the processing quality and efficiency of the nuts. At the same time, the feeding device and its feeding method also have a high degree of automation, capable of automatically completing tasks such as nut collection, screening, and conveyance, reducing manual intervention, lowering labor intensity, and enhancing the overall production efficiency and economic benefits.

The nuts with smaller volume are screened to the bottom of the screen 2424 and fall on the top of the defective material blanking plate 21, while the nuts with larger volume remain on the top of the screening blanking plate 2423 and gradually slide to the transmission mechanism 3. Under the action of the transmission mechanism 3, the nuts with larger volume are orderly conveyed to the next process for further processing. The screened nuts enter the next process respectively, ensuring the processing quality and efficiency of the nuts. At the same time, the shaking of the screen 2424 can effectively prevent the nuts from blocking the screen holes during the screening process and improve the screening effect.

[0023] As Figure 10 shown, the defective material conveying mechanism 4 includes a defective material conveying frame 41. The left side of the rear side of the defective material conveying frame 41 is fixedly connected with a longitudinal conveying table 47. The left side of the rear side of the defective material conveying frame 41 aligned with the longitudinal conveying table 47 is designed with a hollow. A conveying frame side groove 49 is opened on the front side of the defective material conveying frame 41. Both sides of the left side of the front side of the defective material conveying frame 41 are fixedly connected with hydraulic push rod connecting plates 43. The front and rear sides of the inner sides of the two hydraulic push rod connecting plates 43 are fixedly connected with hydraulic push rod connecting blocks 44. The inner wall of the two hydraulic push rod connecting blocks 44 is fixedly connected with a hydraulic push rod 45. The rear end of the hydraulic push rod 45 extends to the inner wall of the defective material conveying frame 41. A plurality of receiving boxes 46 are slidably connected to the inner wall of the defective material conveying frame 41. A push plate 410 is slidably connected to the right side of the inner wall of the conveying frame side groove 49 opened on the front side of the defective material conveying frame 41. The rear side of the push plate 410 extends to the inner wall of the defective material conveying frame 41 and the left side is attached to the right side of the rightmost receiving box 46. The front side of the left side of the push plate 410 is fixedly connected with a spring 48. The left end of the spring 48 is fixedly connected to the right side of the right hydraulic push rod connecting plate 43. The leftmost receiving box 46 is aligned with the longitudinal conveying table 47 fixed on the left side of the rear side of the defective material conveying frame 41. The front side of the leftmost receiving box 46 is attached to the rear end of the hydraulic push rod 45; The smaller nuts slide down through the defective material discharging inclined plate 23 into the leftmost material receiving box 46. When the leftmost material receiving box 46 is filled with smaller nuts, the hydraulic push rod 45 is activated to push the leftmost material receiving box 46 to slide backward until it is pushed to the top of the longitudinal conveyor table 47 and conveyed to the next processing link through the longitudinal conveyor table 47. At the same time, the spring 48 is compressed to prepare for the reset of the push plate 410. After the leftmost material receiving box 46 is pushed away, the spring 48 releases energy to push the push plate 410 to move leftward, thereby pushing the remaining material receiving boxes 46 to slide leftward in sequence, so that the next material receiving box 46 moves to the leftmost position to continue receiving the smaller nuts sliding down through the defective material discharging inclined plate 23. In this way, the whole device can automatically and continuously complete the collection and conveying of smaller nuts, greatly improving the processing efficiency and automation degree. The design of the whole defective material conveying mechanism 4 realizes the rapid collection and automatic box changing of smaller nuts, improving the efficiency and automation degree of nut processing.

[0024] In addition, the present invention also relates to a feeding device and a feeding method for nut processing, including the following steps: Step 1: Nuts are poured into the storage bin 2414 and enter the material distribution and discharging assembly 2416 through the storage bin discharging funnel 2415. The motor 24169 is started, and the turntable 24170 and the second turntable 24172 rotate, driving the columnar horizontal rotating rod 24173, the rotating roller 24174 and the baffle 24175 to rotate synchronously. The baffle 24175 intermittently guides the nuts to the discharging bin 24178 to prevent blockage and ensure that the nuts enter the next stage evenly and orderly; Step 2: The nuts fall from the discharging bin 24178 onto the screening material discharging plate 2423. The fourth turntable 24215 is driven by the second crawler 24177 to rotate the second transmission shaft 24213, the transmission shaft 24211 and the third crawler 24212. The third crawler 24212 drives the second columnar horizontal rotating rod 2429 and the rhombic abutting block 24216 to rotate. The abutting block impacts the disc 2428, causing the inverted L-shaped shaking block 2425 to shake in the L-shaped side rod 2426, and the sieve mesh 2424 shakes accordingly to screen the nuts. The small nuts pass through the sieve mesh 2424 to the defective material discharging plate 21, and the large nuts remain on the screening material discharging plate 2423 and slide to the transmission mechanism 3 for processing; Step 3: The smaller nuts after screening slide down along the defective material discharging inclined plate 23 into the leftmost material receiving box 46 of the defective material conveying mechanism 4. When the material receiving box 46 is full, the hydraulic push rod 45 is activated to push the material receiving box 46 to slide backward onto the longitudinal conveyor table 47, and then it is conveyed to the next processing link through the longitudinal conveyor table 47; Step 4: The spring 48 compresses to prepare for the reset of the push plate 410. After the leftmost receiving bin 46 is pushed away, the spring 48 releases energy, pushing the push plate 410 to move leftward, and then pushing the remaining receiving bins 46 to slide leftward in sequence, so that the next receiving bin 46 moves to the leftmost position to continuously receive the smaller nuts that slide down. This process realizes the automatic collection and continuous transmission of the smaller nuts, significantly improving the processing efficiency and automation level.

[0025] Working principle of the present invention: During use, the nuts enter the lower inclined plate 24161 through the blanking funnel 2415 of the storage bin. The motor 24169 is started, and the output end of the motor 24169 drives the turntable 24170 to rotate. The turntable 24170 drives the second turntable 24172 to rotate through the track 24171, and then drives the columnar horizontal rotating rod 24173 to rotate. The rotation of the columnar horizontal rotating rod 24173 drives the roller 24174 and the baffle 24175 on the outer wall of the roller 24174 to rotate synchronously. The falling nuts are intermittently fed into the blanking bin 24178 through the rotating baffle 24175. The nuts continue to be fed from the bottom of the blanking bin 24178 to the top of the screening blanking plate 2423. At this time, the two fourth turntables 24215 drive the two second transmission shafts 24213 to rotate synchronously through the transmission of the second track 24177, and then drive the transmission shaft 24211 and the third track 24212 to rotate, so that the second columnar horizontal rotating rod 2429 rotates. The two rhombic abutting blocks 24216 on the outer wall of the second columnar horizontal rotating rod 2429 rotate synchronously, continuously abutting against the disc 2428, so that the disc 2428 drives the inverted L-shaped vibrating block 2425 to reciprocate inside the inner wall of the L-shaped side rod 2426. The inverted L-shaped vibrating block 2425 drives the screen 2424 to reciprocate through the screening blanking plate 2423 to screen the nuts falling from the top of the screening blanking plate 2423. The smaller nuts are screened to the bottom of the screen 2424, fall on the defective material blanking plate 21, and slide down to the receiving bin 46 of the defective material conveying mechanism 4 through the defective material lower inclined plate 23. When the receiving bin 46 is full of smaller nuts, the hydraulic push rod 45 is started to push the receiving bin 46 to slide backward to the top of the longitudinal conveying table 47 and is conveyed to the next processing link through the longitudinal conveying table 47. The larger nuts continue to stay on the top of the screening blanking plate 2423 and gradually slide to the transmission mechanism 3. Under the action of the transmission mechanism 3, the larger nuts are orderly conveyed to the next process for further processing.

10. The feeding method of a feeding device for nut processing according to any one of claims 1-9, characterized in that: It includes the following steps: Step 1: Pour the nuts into the storage bin (2414), and they enter the material distribution and feeding component (2416) through the feeding funnel (2415) of the storage bin. Start the motor (24169), and the turntable (24170) and the second turntable (24172) rotate, driving the columnar horizontal rotating rod (24173), the rotating roller (24174) and the baffle (24175) to rotate synchronously. The baffle (24175) intermittently guides the nuts to the feeding bin (24178), preventing blockage and ensuring that the nuts enter the next stage evenly and orderly. Step 2: The nuts fall from the feeding bin (24178) onto the screening and feeding plate (2423). The fourth turntable (24215) is driven by the second track (24177), causing the second transmission shaft (24213), the transmission shaft (24211) and the third track (24212) to rotate. The third track (24212) drives the second columnar horizontal rotating rod (2429) and the rhombic abutting block (24216) to rotate. The abutting block impacts the disc (2428), causing the inverted L-shaped shaking block (2425) to shake within the L-shaped side rod (2426). As a result, the sieve (2424) shakes, screening the nuts. The small nuts pass through the sieve (2424) to the defective material discharging plate (21), and the large nuts remain on the screening and feeding plate (2423) and slide towards the transmission mechanism (3) for processing. Step 3: The smaller nuts after screening slide along the defective material discharging inclined plate (23) into the leftmost receiving box (46) of the defective material conveying mechanism (4). When this receiving box (46) is full, the hydraulic push rod (45) starts, pushing the receiving box (46) to slide backward onto the longitudinal conveying table (47), and then being conveyed to the next processing link through the longitudinal conveying table (47). Step 4: The spring (48) is compressed to prepare for the reset of the push plate (410). After the leftmost receiving box (46) is pushed away, the spring (48) releases energy, pushing the push plate (410) to move leftward, and then pushing the remaining receiving boxes (46) to slide leftward in sequence, moving the next receiving box (46) to the leftmost position to continue receiving the sliding smaller nuts. This process realizes the automatic collection and continuous transmission of the smaller nuts, significantly improving the processing efficiency and automation level.
