[0002] Scallions are mainly distributed in Northwest, Northeast, and North China. They hold an extremely important position among Chinese vegetables. Currently, scallion processing equipment on the market is primarily semi-automatic, still requiring manual labor for tasks such as turning or repositioning the scallions. Furthermore, processing equipment typically only performs simple tasks like root cutting and peeling; many processes still rely on manual labor, such as weighing and packaging. Therefore, existing scallion processing equipment is single-process machinery with a low degree of mechanization, affecting production efficiency and processing quality, and failing to meet the needs of large-scale production. Summary of the Invention

One roller is connected to the drive shaft and is the driving roller. The other two rollers are driven rollers. The two driven rollers are located between the feeding conveyor belt and the drive shaft, and are spaced apart along the movement direction of the feeding conveyor belt. Each driven roller has a lifting rod connected to both ends of its central shaft. The lifting rod is connected to a fixed base, which is mounted on the frame assembly. The lifting rod passes through the fixed base and can move in a direction perpendicular to the feeding conveyor belt.

[0008] Preferably, the cutting mechanism includes a disc cutter, a cutting motor, and a first waste collection box. The disc cutter has serrations in its circumference, the output shaft of the cutting motor is driven and connected to the central shaft of the disc cutter, and the first waste collection box is located below the disc cutter.

[0009] Preferably, the clamping mechanism includes an upper clamping arm, an upper clamping arm drive assembly, a lower clamping arm, a lower clamping arm drive assembly, and a vision recognition module.

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] See Figure 1 and Figure 2As shown, an embodiment of the present invention provides a primary processing device for scallions, including a frame assembly 10. A feeding device 11, a cutting device 12, a peeling device 13, a transfer device 14, a weighing device 15, and a packaging device 16 are mounted on the frame assembly 10. The frame assembly 10 is used to support and install the feeding device 11, the cutting device 12, the peeling device 13, the transfer device 14, the weighing device 15, and the packaging device 16. The feeding device 11 includes a feeding conveyor belt 111, which transports the scallions to be processed to the cutting device 12 and then transports the cut scallions to the peeling device 13. The cutting device 12 includes two cutting mechanisms, which are arranged opposite each other on both sides of the feeding conveyor belt 111 in the width direction, for cutting off the root and tail of the scallions respectively. The peeling device 13 includes a clamping mechanism for holding the scallions, a vision recognition module for identifying the scallions, and a nozzle 131 for spraying high-pressure gas to peel the scallions. The clamping mechanism, vision recognition module, and nozzle 131 are located at the end of the feeding conveyor belt 111 in the direction of movement. The transfer device 14 includes a transfer conveyor belt 141 for conveying the peeled scallions to the weighing device 15. The weighing device 15 includes a weighing mechanism and a pushing mechanism. The weighing mechanism is used to weigh the scallions, and the pushing mechanism is used to push the scallions to the packaging device 16 when the weight of the scallions is not less than a preset weight. The packaging device 16 includes a support platform and a winding mechanism. The support platform is located below the weighing mechanism and is used to support the scallions, while the winding mechanism is used to bundle the scallions. When the scallions to be processed are placed above the feeding conveyor belt 111, the feeding conveyor belt 111 moves, and the scallions follow the feeding conveyor belt 111. When the scallions pass the cutting device 12, two cutting mechanisms perform bidirectional cutting on the scallions at the root and tail, standardizing the product specifications and creating favorable conditions for the subsequent peeling process (the soil and yellow leaves on the surface of the scallions are easier to remove after bidirectional cutting). After being cut, the scallions continue to move with the feeding conveyor belt 111 to the peeling device 13. When the vision recognition module recognizes that the scallions are held by the clamping mechanism, the nozzle 131 performs all-round pneumatic cleaning and peeling of the scallions, efficiently removing surface adhering substances. The process removes soil, yellow leaves, and impurities without washing, thus preventing the scallions from becoming damp and spoiling. After peeling, the clamping mechanism releases the scallions and sends them to the transfer conveyor belt 141 of the transfer device 14. The transfer conveyor belt 141 transports the scallions to the weighing device 15. When the scallions fall to the weighing device, their weight is measured and compared with a preset weight value. If the weight meets the product standard, the pushing mechanism is activated to accurately push the qualified product to the final packaging device 16. If it does not meet the standard, the scallions wait for the next peeling before being sent to the weighing device 15. The scallions sent to the packaging device 16 fall onto the carrying platform, where the winding mechanism binds them. The entire process does not require the operator to stop and restart the machine, achieving continuous and uninterrupted production and improving production efficiency.

[0023] In this embodiment, the scallion primary processing equipment also includes a controller. The controller is electrically connected to the feeding device 11, cutting device 12, peeling device 13, transfer device 14, weighing device 15, and packaging device 16, respectively, to achieve automated control, reduce human intervention and safety accidents, and improve equipment operating efficiency and production efficiency. It should be noted that the controller is a prior art technology and can be a programmable controller, such as a PLC or a microcontroller.

[0024] In this embodiment, as Figure 4 As shown, the frame assembly 10 includes a frame structure 101 and casters 102 located at the four corners of the bottom of the frame structure 101. A feeding device 11, a cutting device 12, a peeling device 13, a transfer device 14, a weighing device 15, and a packaging device 16 are respectively installed inside the frame structure 101. Through this arrangement, the frame structure 101 can protect the various devices installed inside it, preventing equipment damage; and by providing casters 102 at the bottom of the frame structure 101, it facilitates the movement of equipment.

[0025] In this embodiment, as Figures 1 to 4 As shown, the feeding device 11 is a conventional conveyor belt mechanism. The feeding conveyor belt 111 is horizontally mounted on the frame structure 101 via a support structure and is located within the frame structure 101. The feeding conveyor belt 111 is driven and connected to the feeding motor 113 mounted on the support structure via a feeding transmission mechanism 112 (such as a synchronous belt pulley mechanism). The scallions are placed above the feeding conveyor belt 111, with both ends of the scallions (i.e., the root and the tail of the leaves) located at the two ends of the feeding conveyor belt 111 in the width direction. The feeding end and unloading end of the feeding conveyor belt 111 are arranged along its length direction. When the feeding conveyor belt 111 is running, it transports the scallions from the feeding end to the unloading end of the feeding conveyor belt 111.

[0026] In this embodiment, as Figure 2As shown, a pressing mechanism 17 is provided above the feeding conveyor belt 111. The pressing mechanism 17 includes a pressing belt drive assembly, two pressing roller groups, and two pressing belts 171. The two pressing belts 171 are spaced apart on both sides of the feeding conveyor belt 111 in the width direction. The two pressing belts 171 cover the outer surface of the pressing rollers 172 of the two pressing roller groups respectively. The pressing belt drive assembly is driven by one of the pressing rollers 172 in each pressing roller group to drive the pressing belts 171 to rotate. With the above arrangement, the pressing mechanism 17 applies a constant downward pressure to the scallions, ensuring that the scallions are tightly attached to the surface of the feeding conveyor belt 111 and preventing the scallions from jumping or shifting during the conveying process. Specifically, the belt pressing drive assembly includes a belt pressing motor 173, a drive shaft 174, and a support base 175. The belt pressing motor 173 and the support base 175 are respectively fixed on the frame assembly 10. The belt pressing motor 173 is drivenly connected to the drive shaft 174, and the drive shaft 174 is rotatably connected to the support base 175. Each roller group includes three rollers 172. One roller 172 is connected to the drive shaft 174 and is the driving roller. The other two rollers 172 are driven rollers. The two driven rollers are located between the feeding conveyor belt 111 and the drive shaft 174, and the two driven rollers are spaced apart along the movement direction of the feeding conveyor belt 111. Each driven roller has a lifting rod 176 connected to both ends of its central shaft. The lifting rod 176 is connected to a fixed base 177. The fixed base 177 is mounted on the frame assembly 10. The lifting rod 176 passes through the fixed base 177 and can move in a direction perpendicular to the feeding conveyor belt 111. Before the equipment starts working, the height of the pressing belt 171 is adjusted by moving the lifting rod 176 up and down. During the operation of the feeding conveyor belt 111, the pressing belt 171 is located above and in contact with the scallion. The pressing belt motor 173 drives the transmission shaft 174 to rotate. The transmission shaft 174 causes the two pressing belts 171 to rotate synchronously through the driving wheel and the driven wheel, and the rotation direction is the same as the movement direction of the feeding conveyor belt 111.

[0027] In this embodiment, as Figures 1 to 4 As shown, the cutting mechanism includes a disc cutter 121, a cutting motor 122, and a first waste collection box 123. The disc cutter 121 has serrations along its circumference. The output shaft of the cutting motor 122 is driven and connected to the central shaft of the disc cutter 121. The first waste collection box 123 is located below the disc cutter 121. The disc cutter 121 is located between the feeding end and the unloading end of the feeding conveyor belt 111. When the cutting motor 122 is started, it drives the disc cutter 121 to rotate. When the scallions on the feeding conveyor belt 111 pass by the disc cutter 121, the two disc cutters 121 cut off the root and leaf tail of the scallion respectively, which can make the length of the scallion uniform. The waste generated during the cutting process (such as root residue and yellow leaves at the tail) falls directly into the first waste collection box 123 below for centralized treatment and avoids contamination of subsequent processes.

[0028] In this embodiment, as Figures 1 to 4As shown, the clamping mechanism includes an upper clamping arm 132, an upper clamping arm drive assembly 133, a lower clamping arm 134, and a lower clamping arm drive assembly 135. The upper clamping arm 132 and the lower clamping arm 134 are located at the end of the feeding conveyor belt 111, and the upper clamping arm 132 and the lower clamping arm 134 are arranged alternately. The upper clamping arm drive assembly 133 is used to drive the upper clamping arm 132 to rotate to press or release the scallion, and the lower clamping arm drive assembly 135 is used to drive the lower clamping arm 134 to rotate to receive or release the scallion. The upper clamping arm drive assembly 133 includes an upper drive motor 1331, an upper driving gear 1332, an upper driven gear 1333, and an upper rotating shaft 1334. The upper drive motor 1331 is driven by the upper driving gear 1332, which meshes with the upper driven gear 1333. The upper driven gear 1333 is mounted on the upper rotating shaft 1334, which is mounted on the frame structure 101 via an upper mounting base 1335. The upper clamping arm 132 is connected to the upper rotating shaft 1334. The upper drive motor 1331 is mounted on a mounting plate 136, and the upper rotating shaft 1334 passes through and is rotatably connected to the mounting plate 136. The upper drive motor 1331 drives the upper driving gear 1332 to rotate, causing the upper driving gear 1332 to mesh with the upper driven gear 1333, thereby rotating the upper clamping arm 132 on the upper rotating shaft 1334. The lower clamping arm drive assembly 135 includes a lower drive motor 1351, a lower drive gear 1352, a lower driven gear 1353, and a lower rotating shaft 1354. The lower drive motor 1351 is driven by the lower drive gear 1352, which meshes with the lower driven gear 1353. The lower driven gear 1353 is mounted on the lower rotating shaft 1354, which is mounted on the frame structure 101 via a lower mounting base 1355. The lower clamping arm 134 is connected to the lower rotating shaft 1354. The lower drive motor 1351 is mounted on a mounting plate 136, and the lower rotating shaft 1354 passes through and is rotatably connected to the mounting plate 136. The lower drive motor 1351 drives the lower drive gear 1352 to rotate, causing the lower drive gear 1352 to mesh with the lower driven gear 1353 and thus rotate the lower clamping arm 134 on the lower rotating shaft 1354.

[0029] In this embodiment, as Figure 2 As shown, multiple upper clamping arms 132 are connected to the upper rotating shaft 1334 and are spaced apart from each other along the width direction of the feeding conveyor belt 111. Multiple lower clamping arms 134 are connected to the lower rotating shaft 1354 and are also spaced apart from each other along the width direction of the feeding conveyor belt 111. The multiple upper clamping arms 132 and multiple lower clamping arms 134 are arranged in a one-to-one correspondence. Through this arrangement, the high-pressure gas being sprayed can fully contact the scallions, efficiently removing surface dirt, dry skin, yellow leaves, and impurities, ensuring both peeling efficiency and cleanliness.

[0030] In this embodiment, as Figure 2As shown, the upper clamping arm 132 is in a downward-curving arc shape, and the lower clamping arm 134 is in an upward-curving arc shape. This design prevents the upper clamping arm 132 and the lower clamping arm 134 from squeezing and damaging the onion body during clamping.

[0031] In this embodiment, as Figures 1 to 4 As shown, the peeling device 13 also includes a second waste collection box 137, which is located below the clamping mechanism and is used to collect fallen soil, dried bark, yellow leaves and impurities.

[0032] In this embodiment, as Figures 1 to 4 As shown, the visual recognition module uses a high-definition camera 138 to collect image data in real time to identify the location of the scallion. Initially, the upper clamping arm 132 is in a vertical position, and the lower clamping arm 134 is in a horizontal position. When the scallion falls into the lower clamping arm 134, the high-definition camera 138, located above the clamping mechanism, recognizes the scallion's position. The upper clamping arm 132 then rotates 90° downwards towards the lower clamping arm 134. Once the upper clamping arm 132 is in position, the lower clamping arm 134 works in conjunction with the upper clamping arm 132 to clamp the scallion. The nozzle 131 sprays high-pressure gas to perform all-around pneumatic cleaning of the scallion. After the pneumatic cleaning reaches the preset time, the nozzle 131 stops working, and the cleaning is complete. The lower clamping arm 134 rotates 90° downwards to a vertical position, and the upper clamping arm 132 rotates 90° upwards to a vertical position. After the scallion falls onto the transfer conveyor belt 141, the lower clamping arm 134 rotates 90° upwards to reset and prepare for the next scallion cleaning, enabling continuous operation.

[0033] In this embodiment, as Figures 1 to 4 As shown, the nozzle 131 is located above the clamping mechanism. The nozzle 131 is connected to the air compressor 140 through the pipe 139. Both the pipe 139 and the air compressor 140 are mounted on the frame structure 101.

[0034] In this embodiment, as Figures 1 to 4 As shown, the transfer device 14 is a conventional conveyor belt mechanism. The transfer conveyor belt 141 is horizontally installed on the frame structure 101 via a support structure and is located within the frame structure 101. The transfer conveyor belt 141 is driven and connected to the transfer motor 143 installed on the support structure via a transfer transmission mechanism 142 (such as a synchronous belt pulley mechanism). The loading end of the transfer conveyor belt 141 is located below the clamping mechanism, and the unloading end of the transfer conveyor belt 141 is located above the weighing mechanism. When the transfer conveyor belt 141 is running, it transports the peeled scallions from the loading end to the unloading end of the transfer conveyor belt 141.

[0035] In this embodiment, as Figure 3 and Figure 4As shown, the weighing mechanism includes a weighing platform 151, a weighing strain gauge 152, and a support platform 153. The weighing platform 151 is located at the end of the conveyor belt 141 in the direction of movement. The weighing strain gauge 152 is disposed between the weighing platform 151 and the support platform 153. The support platform 153 is mounted on the frame assembly 10. The weighing platform 151 is located below the unloading end of the conveyor belt 141 and is used to receive the scallions. The support platform 153 is used to mount the weighing platform 151 and the weighing strain gauge 152. When the scallions fall from the conveyor belt 141 onto the weighing platform 151, the weighing strain gauge 152 obtains the weight data.

[0036] In this embodiment, as Figure 4 and Figure 5 As shown, the pushing mechanism includes a pusher block 154 and a pusher block drive assembly. The pusher block 154 is used to push the scallions to the packaging device 16. The pusher block drive assembly is driven to the pusher block 154, enabling the pusher block 154 to reciprocate between the transfer conveyor belt 141 and the packaging device 16. Specifically, the pusher block drive assembly includes a guide seat 155, a pusher rack 156, a pusher gear 157, and a pusher motor 158. The output end of the pusher motor 158 is connected to the central shaft of the pusher gear 157. The pusher gear 157 meshes with the pusher rack 156. The pusher rack 156 is slidably connected to the guide seat 155. The end of the pusher rack 156 near the weighing mechanism is connected to the pusher block 154. The guide seat 155 and the pusher motor 158 are mounted on the frame assembly 10. The push motor 158 drives the push gear 157 to rotate. The push gear 157 meshes with the push rack 156, causing the push rack 156 to drive the push block 154 to move along the transfer conveyor belt 141 to the packaging device 16. The guide seat 155 has a guide channel extending along the transfer conveyor belt 141 to the packaging device 16. The push rack 156 passes through the guide channel, with one end of the push rack 156 extending out of the guide channel near the packaging device 16 and connecting to the push block 154. An opening slot 1551 communicating with the guide channel is provided above the guide seat 155. The push gear 157 is located in the opening slot 1551 and meshes with the push rack 156. This arrangement ensures that the push rack 156 moves along the guide channel within the guide seat 155, preventing the push rack 156 from deviating.

[0037] In this embodiment, as Figures 1 to 4 as well as Figures 6 to 9As shown, the support platform includes two support platforms 161 spaced apart below the weighing device 15. The winding mechanism includes an annular guide rail 162, a winding ring 163, a drive gear 164, a winding motor 165, and an electric push rod 166. The annular guide rail 162 is vertically arranged between the two support platforms 161, and its axis extends along the arrangement direction of the two support platforms 161. A scallion inlet 1621 is provided above the annular guide rail 162, located below the weighing device 15. The winding ring 163 is rotatably mounted on the annular guide rail 162. The winding ring 163 has a notch that matches the scallion inlet 1621. A gear ring structure that meshes with the drive gear 164 is provided on the inner circumference of the winding ring 163. A rotatable pulley 167 is mounted on one side surface of the winding ring 163. The output shaft of the winding motor 165 is driven by the drive gear 164. The electric push rod 166 is located on the winding ring 163 away from the pulley 167. On one side, a pressure block 168 is connected to the end of the telescopic rod of the electric push rod 166. A blade 169 is provided at the front end of the cylinder of the electric push rod 166. The blade 169 is tangent to the outer edge of the telescopic rod of the electric push rod 166. The length of the blade 169 is greater than the diameter of the telescopic rod of the electric push rod 166 and smaller than the diameter of the front end of the cylinder of the electric push rod 166. The side of the pressure block 168 facing the electric push rod 166 is provided with a groove 1681 that matches the blade 169. In the initial state, the belt pulley 167 is fitted with... A tape roll 1671 is provided. The end of the tape pulled out from the tape roll 1671 is pressed against the pressure block 168 by the front end of the cylinder of the electric push rod 166. The blade 169 is inserted into the blade groove 1681. When packaging, when the winding ring 163 rotates to the first preset number of turns, the telescopic rod of the electric push rod 166 extends to the preset position. When the winding ring 163 rotates to the second preset number of turns, the winding ring 163 stops rotating, and the telescopic rod of the electric push rod 166 retracts and resets, causing the blade 169 to cut the tape. Specifically, the annular guide rail 162 is installed inside the frame structure 101, and its inner side has an arc-shaped protrusion 1622. The annular guide rail 162 is a circular ring structure with an opening composed of three arc-shaped blocks. The side of the winding ring 163 that is slidably connected to the annular guide rail 162 has an arc-shaped groove 1631 that cooperates with the arc-shaped protrusion 1622. The arc-shaped protrusion 1622 is inserted into the arc-shaped groove 1631 to make the winding ring 163 move along the arc-shaped protrusion 1622. The blade 169 is a rectangular sheet structure. The blade 169 is inclined from top to bottom and one side of it is tangent to the surface of the telescopic rod of the electric push rod 166.

[0038] In this embodiment, as Figure 4 As shown, the winding mechanism also includes two mutually spaced limiting gears 170. The two limiting gears 170 are rotatably mounted on the frame structure 101 and respectively mesh with the winding ring 163. The two limiting gears 170 are respectively spaced with the drive gear 164 to ensure stable operation of the winding ring 163 and prevent the winding ring 163 from disengaging from the annular guide rail 162.

[0039] In this embodiment, the controller is electrically connected to the feeding motor 113, the cutting motor 122, the upper drive motor 1331, the lower drive motor 1351, the high-definition camera 138, the air compressor 140, the transfer motor 143, the weighing strain gauge 152, the pushing motor 158, the winding motor 165, the electric push rod 166, and the pressing motor 173.

[0040] An embodiment of the present invention provides a primary processing device for scallions, the working principle of which is as follows: During operation, the feeding motor 113 drives the feeding conveyor belt 111 to run continuously, and the pressing motor 173 drives the pressing belt 171 to rotate, smoothly conveying the scallions to the cutting area; the cutting motor 122 drives the disc cutter 121 to rotate and cut the roots and tails of the scallions in both directions. Waste generated during the cutting process (such as root remnants and yellow leaves at the tail) falls into the first waste collection box 123 under the action of gravity; the cut scallions fall from the unloading end of the feeding conveyor belt 111 into the lower clamping arm 134, which is in a horizontal position, and the high-definition camera 138... When the scallion is detected to be in the lower clamping arm 134, the upper clamping arm 132, which is in a vertical position, rotates downwards by 90° to press the scallion. The nozzle 131 sprays high-pressure gas for pneumatic cleaning. After cleaning is completed, the lower clamping arm 134 rotates downwards by 90°, and the upper clamping arm 132 rotates upwards by 90°. After the scallion falls onto the transfer conveyor belt 141, the lower clamping arm 134 rotates upwards to reset. The transfer conveyor belt 141 transports the scallion to the weighing platform 151. The weighing strain gauge 152 collects weight data in real time and sends it to the controller, comparing the weight data with the preset weight value. If the weight is equal to or greater than the preset weight value, the controller immediately starts the push motor 158, causing the push gear 157 and push rack 156 to drive the push block 154 to move, pushing the scallion to the carrying platform 161; if the weight is less than the preset weight value, it waits for the next batch of scallions to be delivered until the weight standard is met, then starts the push motor 158; at the same time as the push motor 158 starts, the winding motor 165 starts, the winding motor 165 drives the drive gear 164 to rotate, and the winding ring 163 and the limit gear 170 rotate synchronously. The tape is then wrapped around the scallion. When the wrapping ring 163 rotates to the first preset number of turns (e.g., the second turn), the controller controls the telescopic rod of the electric push rod 166 to extend to the preset position. When the wrapping ring 163 rotates to the second preset number of turns (e.g., the fourth turn), the telescopic rod of the electric push rod 166 retracts and resets. The blade 169 cuts the tape wrapped around the telescopic rod of the electric push rod 166, completing the scallion packaging. At this time, the end of the tape roll 1671 is pressed tightly by the front end of the electric push rod 166 and the pressure block 168, thus preparing for the next packaging.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
