Description

Technical Field

[0001] This invention relates to the field of vermicelli processing and conveying technology, specifically to an automatic conveying device for sweet potato vermicelli processing. Background Technology

[0002] A patent application for an automatic conveying device for potato vermicelli processing, with publication number CN120887227B, includes a first conveyor belt with a vermicelli-collecting gap in the middle. It further includes a vermicelli-collecting mechanism that automatically collects vermicelli at the gap and distributes it evenly using a speed difference; a first drive mechanism that controls the up-and-down movement of the vermicelli-collecting mechanism to remove it from the first conveyor belt; and a second drive mechanism that drives the vermicelli-collecting mechanism to rotate back and forth to move it to the next processing step. The advantages are: this application automates the conveying, vermicelli-collecting, and even distribution processes in potato vermicelli processing, reducing manual operation, improving production efficiency, and reducing labor intensity.

[0003] However, existing vermicelli conveying devices, including those mentioned above, still have significant drawbacks in actual production: freshly processed wet vermicelli needs to be cut into fixed-length sections and hung on drying poles before being conveyed to the drying process. Existing equipment can only mechanically position the vermicelli to make the lengths of both ends as similar as possible, but it cannot guarantee an even weight distribution of the vermicelli on both sides of the drying pole, making it prone to uneven weight distribution and center of gravity shift. The vermicelli on the heavier side will gradually slide down due to gravity during conveying and drying, which not only easily causes vermicelli to fall off, become contaminated, and waste raw materials, but also leads to uneven stress on the drying pole, causing malfunctions such as pole jamming and pole falling, affecting the continuous and stable operation of the entire production line. At the same time, manual leveling increases labor intensity and reduces the efficiency of automated production. Summary of the Invention

[0004] The problem this invention aims to solve is that existing vermicelli hanging rods have an unbalanced weight distribution on both sides during conveying, making them prone to falling off and requiring manual leveling, thus failing to achieve purely mechanical adaptive adjustment.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: an automatic conveying device for sweet potato vermicelli processing, comprising a first conveying mechanism and a second conveying mechanism. The first conveying mechanism is used to continuously convey the vermicelli and cut it into fixed-length segments, which are then suspended above the support assembly. The second conveying mechanism is a double-sided synchronous conveying structure used to support and convey the support components. During conveying, the support components are supported at both ends and hollow in the middle. The support assembly is used to suspend the vermicelli and allow it to enter the subsequent drying process; The support assembly is equipped with a balancing component, which is a purely mechanical hydraulic adaptive structure that can automatically detect the weight difference between the two sides of the vermicelli and drive the support assembly to fine-tune its position so that the weight of the vermicelli on both sides tends to be balanced, thus preventing the vermicelli from falling off.

[0006] The balancing component relies on the pressure of the limiting plate to trigger the action, and realizes weight detection and adaptive adjustment through hydraulic oil pressure transmission. The entire adjustment process is sensorless, electronically controlled, and requires no manual intervention.

[0007] Preferably, the first conveying mechanism includes a belt conveyor, on which a conveying roller, a cutting blade, and an auxiliary roller are sequentially arranged, and the conveying roller of the belt conveyor is connected to the conveying roller, the cutting blade, and the auxiliary roller in a driving connection.

[0008] Preferably, the second conveying mechanism includes a first chain conveyor and a second chain conveyor. The first chain conveyor is inclined and disposed below the belt conveyor, and the second chain conveyor is horizontally disposed on one side of the first chain conveyor. The first chain conveyor and the second chain conveyor are connected by a guide plate.

[0009] Preferably, limiting plates are provided on both sides above the second chain conveyor, and conveying blocks are provided on the chain of the second chain conveyor.

[0010] Preferably, the support assembly includes a support rod, on which an adjustment housing is rotatably connected, and the adjustment housing has a threaded groove.

[0011] Preferably, the support rod has a sliding groove, and an adjusting rod is slidably connected to the sliding groove, with the adjusting rod inserted into the threaded groove.

[0012] Preferably, the support assembly further includes a balance plate, which is hinged to the support rod, and the balance plate has ventilation holes.

[0013] Preferably, the balancing assembly includes a first insert rod, with first insert rods inserted into both sides of the support rod, and hydraulic oil is provided in the inner cavity of both sides of the support rod, and a first spring is provided on the first insert rod.

[0014] Preferably, a fixing block is provided on the support rod, the inner cavity of the fixing block is connected to the inner cavity of the first insert rod, a second insert rod is inserted into the fixing block, a slider is slidably connected to the side of the balance plate near the fixing block, the end of the second insert rod away from the fixing block is hinged to the slider, and a second spring is sleeved on the second insert rod.

[0015] Preferably, a third rod is inserted into the fixing block, the third rod is fixedly connected to the adjusting rod, and a third spring is sleeved on the third rod.

[0016] Compared with the prior art, the technical solution of the present invention has the following advantages: This invention achieves adaptive weight balance adjustment throughout the entire process of suspended vermicelli conveying by setting a balancing component on the support assembly and cooperating with a double-sided chain-type second conveying mechanism. It eliminates the need for sensors and electronic control assistance, relying solely on a purely mechanical structure and hydraulic transmission to correct the center of gravity. This effectively solves the problem of vermicelli falling off and slipping due to uneven weight distribution on both sides in traditional devices, significantly reducing raw material loss and vermicelli contamination risks during production, and ensuring that the vermicelli maintains a complete and orderly suspended state before conveying and drying. The design of the limiting plate and the first insert rod automatically triggers the balancing component when the support assembly enters the adjustment area, pushing the balancing plate to unfold and flexibly contact the vermicelli. This achieves real-time weight detection of the vermicelli while avoiding deformation and breakage of the wet vermicelli due to rigid contact. The ventilation hole structure balances the support without affecting airflow on the vermicelli surface, providing good conditions for subsequent drying. The overall structure operates stably and smoothly, making it suitable for continuous production scenarios. This invention integrates vermicelli conveying, fixed-length cutting, suspension support, and adaptive balance adjustment into one unit. The first and second conveying mechanisms adopt a synchronous transmission design, achieving continuous matching between vermicelli conveying and the movement of the support components. This eliminates the need for frequent equipment start-ups and shutdowns, reduces mechanical impact and component wear, and extends the service life of the device. The balance component transmits pressure via hydraulic oil, driving the third insert rod and the adjusting rod to rotate the adjusting housing slightly through the threaded groove. This precisely corrects the vermicelli's center of gravity shift, quickly aligning the weight on both sides. The adjustment process requires no manual intervention, significantly improving the automation level and production efficiency of vermicelli processing and conveying, while reducing manual labor intensity. The double-sided chain conveyor, in conjunction with the conveying blocks and limiting plates, achieves a stable support at both ends and a completely hollow conveying state in the middle, preventing vermicelli from contacting and entangled with the conveying components, further improving the reliability and smoothness of the conveying process.

[0021] like Figures 1-10 As shown, the present invention provides an automatic conveying device for processing sweet potato vermicelli, comprising a first conveying mechanism 1 and a second conveying mechanism 2. The first conveying mechanism 1 is used to continuously convey the vermicelli and cut it into fixed-length segments, which are then suspended above the support assembly 3. The second conveying mechanism 2 is a double-sided synchronous conveying structure used to support and convey the support component 3. During conveying, the support component 3 is supported at both ends and hollow in the middle. Support component 3 is used to suspend the vermicelli and allow it to enter the subsequent drying process; The support component 3 is equipped with a balancing component 4, which is a purely mechanical hydraulic adaptive structure that can automatically detect the weight difference between the two sides of the vermicelli and drive the support component 3 to fine-tune its position so that the weight of the vermicelli on both sides tends to be balanced, thus preventing the vermicelli from falling off.

[0022] The working principle and usage process of this invention: The processed vermicelli is conveyed by the first conveying mechanism 1, while the second conveying mechanism 2 moves the support component 3. When the support component 3 moves to the unloading point of the first conveying mechanism 1, the first conveying mechanism 1 guides the vermicelli to hang above the support component 3. The first conveying mechanism 1 continues to convey the vermicelli, while the second conveying mechanism 2 moves the support component 3 forward. When the length of the vermicelli on both sides of the support component 3 is basically the same, the first conveying mechanism 1 automatically cuts the long vermicelli. At this time, the vermicelli hanging on the support component 3 is a single piece. The second conveying mechanism... 2. The support component 3 continues to move forward and transports the next support component 3 to suspend the subsequent vermicelli. During the process of transporting vermicelli by the previous support component 3, if the weight on both sides of the support component 3 is unbalanced, the balancing component 4 will support the vermicelli and adjust the state of the vermicelli suspended on both sides of the support component 3, shifting the vermicelli on the heavier side to the lighter side until the vermicelli on both sides is basically balanced. During this process, the second conveying mechanism 2 continuously transports the support component 3 until the next process is to dry it. The whole process realizes continuous and automated operation without stopping and waiting, effectively improving production efficiency and reducing failure rate.

[0023] Please refer to Figures 1-4 The first conveying mechanism 1 includes a belt conveyor 11, on which a conveying roller 12, a cutting blade 13 and an auxiliary roller 14 are sequentially arranged, and the conveying roller of the belt conveyor 11 is connected to the conveying roller 12, the cutting blade 13 and the auxiliary roller 14 in a driving connection.

[0024] The conveying roller of the first conveying mechanism 1 is driven to rotate by a motor. The conveying roller is connected to the rotating shaft of the conveying drum 12, the rotating shaft of the cutting blade 13, and the rotating shaft of the auxiliary roller 14 by a transmission belt. When the conveying roller rotates, it will drive the conveying drum 12, the cutting blade 13, and the rotating shaft to rotate. The vermicelli is conveyed to the conveying drum 12 by the belt conveyor 11. The conveying drum 12 lifts the vermicelli and then lowers it onto the support assembly 3 below through the gap between the cutting blade 13 and the auxiliary roller 14. There is only one blade on the rotating shaft of the cutting blade 13. When the cutting blade 13 rotates 360°, the cutting blade 13 is in contact with the auxiliary roller 14 and cuts the vermicelli.

[0025] Please refer to Figure 4 and Figure 5 The second conveying mechanism 2 includes a first chain conveyor 21 and a second chain conveyor 22. The first chain conveyor 21 is inclined and located below the belt conveyor 11. The second chain conveyor 22 is horizontally located on one side of the first chain conveyor 21. The first chain conveyor 21 and the second chain conveyor 22 are connected by a guide plate 23. Limiting plates 24 are provided on both sides above the second chain conveyor 22. Conveying blocks 25 are provided on the chain of the second chain conveyor 22.

[0026] The first chain conveyor 21 is inclined and transports the support component 3 from bottom to top. The support component 3 is in a low position, which makes it easier for the vermicelli to hang above it. When the vermicelli is cut and hung above the support component 3, the support component 3 is at the highest point of the first chain conveyor 21. At this time, the support component 3 is separated from the first chain conveyor 21 and moves above the guide plate 23. The upper side of the guide plate 23 is inclined. The support component 3 is guided and transported by the guide plate 23 to the conveying block 25 on the second chain conveyor 22. It is transported by the support of the conveying block 25. When the support component 3 is in the area between the limiting plates 24, the balancing component 4 will detect the vermicelli hanging on the support component 3 and adjust the weight of the vermicelli. The second conveying mechanism 2 is hollow in the middle and is supported by the conveying blocks 25 on both sides to achieve the transport. This conveying method can avoid the vermicelli from contacting, sticking or tangling with the conveying components, and ensure that the vermicelli is intact during the suspended transport process.

[0027] Please refer to Figures 6-9 The support assembly 3 includes a support rod 31, an adjusting housing 32 rotatably connected to the support rod 31, a threaded groove 33 on the adjusting housing 32, a sliding groove 34 on the support rod 31, an adjusting rod 35 slidably connected to the sliding groove 34, and the adjusting rod 35 is inserted into the threaded groove 33. The support assembly 3 also includes a balance plate 36, which is hinged to the support rod 31, and a ventilation hole 37 is provided on the balance plate 36.

[0028] The support rods 31 are supported on both sides above the conveying block 25. The balance plate 36 is initially in a vertical state and does not contact the vermicelli suspended on the support assembly 3. The vermicelli is suspended above the adjusting housing 32. When the support assembly 3 moves to the area between the two limiting plates 24, the balance assembly 4 will push the two balance plates 36 to tilt. At this time, the balance plate 36 contacts and supports the vermicelli. The balance plate 36 is used to detect whether the weight of the vermicelli on both sides is basically the same. If they are not the same, the adjusting rod 35 is pushed by the balancing assembly 4. The adjusting rod 35 moves along the slide 34, and the threaded groove 33 of the adjusting housing 32 moves with the adjusting rod 35. At this time, the adjusting housing 32 will rotate, thereby causing the vermicelli suspended above to shift, and adjusting the weight of the vermicelli on both sides until it is in a balanced state.

[0029] Please refer to Figures 6-10 The balancing assembly 4 includes a first insert rod 41. A support rod 31 has first insert rods 41 inserted into both sides, and hydraulic oil is provided in the inner cavities of both sides of the support rod 31. A first spring 42 is provided on the first insert rod 41. A fixing block 43 is provided on the support rod 31, and the inner cavity of the fixing block 43 is connected to the inner cavity of the first insert rod 41. A second insert rod 44 is inserted into the fixing block 43. A slider 46 is slidably connected to the side of the balancing plate 36 near the fixing block 43. The end of the second insert rod 44 away from the fixing block 43 is hinged to the slider 46. A second spring 45 is sleeved on the second insert rod 44. A third insert rod 47 is inserted into the fixing block 43 and is fixedly connected to the adjusting rod 35. A third spring 48 is sleeved on the third insert rod 47.

[0030] The balancing component 4 is driven by pure mechanical hydraulics, utilizing the weight difference of the vermicelli itself to achieve automatic balance adjustment without electrical control. The limiting plate 24 has a pressing plate that is inclined on both sides and horizontal in the middle. When the balancing component 4 moves into the area between the limiting plates 24, the limiting plates 24 first start to press the first insert rod 41. The first insert rod 41 is inserted into a piston at one end of the support rod 31. The first insert rod 41 and the first spring 42 are compressed to start pressing the hydraulic oil in the inner cavity of the support rod 31. The inner cavity on one side of the support rod 31 is respectively connected to two fixed blocks 4. The inner cavity of the second insert rod 44 on one side is connected to the inner cavity of the two second insert rods 44 connected to the two support blocks and the left balance plate 36, as well as the inner cavity of the third insert rod 47 of one of the fixing blocks 43. A piston is also provided at one end of the second insert rod 44 inserted into the fixing block 43. Hydraulic oil pushes the balance plate 36 outward through the second insert rod 44, causing the balance plate 36 to contact and support the vermicelli. At this time, the balance plates 36 on both sides detect the weight of the vermicelli on both sides. When a weight difference occurs between the vermicelli on both sides, this... When the two third insert rods 47 cannot maintain a stable state, the heavier side of the vermicelli presses down on the balance plate 36. The pressing balance plate 36 will cause the second insert rod 44 and the second spring 45 to retract. At this time, since the first insert rod 41 is also squeezed, the hydraulic oil can only flow to the connected third insert rod 47. A piston is also provided at the connection between the third insert rod 47 and the fixed block 43. At this time, the hydraulic oil will push the connected third insert rod 47 to move outward, while the third insert rod 47 on the other side retracts. At this time, the third insert rod 47 moves forward and pushes the adjusting rod 35 towards As the third insert rod 47 on the other side moves, the adjusting rod 35, in conjunction with the threaded groove 33, drives the adjusting housing 32 to rotate by a certain angle, thereby causing the vermicelli to shift until the balance plates 36 on both sides are in a balanced state. At this time, the weight of the vermicelli on both sides is basically the same, and the third insert rod 47 stops moving and is in a stable state. When the support component 3 moves out of the area of ​​the limiting plate 24, the first insert rod 41, without the limitation of the limiting plate 24, rebounds and resets, driving the balance plate 36 to reset. At this time, the balance plate 36 separates from the vermicelli, and the drying effect of the vermicelli is improved through the ventilation hole 37.

The scope of protection of the present invention is defined by the claims.
