Description

Technical Field

[0001] This utility model relates to a scallion packaging equipment, and more particularly to a vertical scallion cleaning, weighing and packaging integrated machine. Background Technology

[0002] There is a need to provide a convenient, fully automatic all-in-one machine to improve the efficiency of scallion processing.

[0003] Patent CN202220136577.5 discloses an automated scallion peeling and cutting device. This device allows for the cutting and peeling of scallions using only one machine, improving work efficiency, reducing worker workload, and enhancing machine usability. A baffle at the bottom of the operating table provides protection, ensuring the scallion roots fall into a collection box for later processing. However, this device still requires manual intervention throughout the process and fails to integrate automation with packaging. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to propose a vertical integrated machine for cleaning, weighing and packaging of scallions, which automates the entire process and improves the standardization and efficiency of scallion processing.

[0005] Technical solution: This utility model includes a first-layer device and a second-layer device. The first-layer device includes a root and leaf unit, a peeling unit, and a segmentation unit. The second-layer device includes a weighing unit and a packaging unit. The peeling unit has a root and leaf unit at one end and a segmentation unit at the other end. The weighing unit is located diagonally below the segmentation unit, and the packaging unit is located above the weighing unit. The root and leaf unit removes the roots and leaves from the scallions. Then, the peeling unit peels the scallions and transports them to the segmentation unit for segmentation. Finally, the weighing unit marks the weight of the segmented scallions and transfers them to the packaging unit for packaging.

[0006] The root and leaf unit includes an inclined groove with symmetrical openings on both sides of the front end of the inclined groove. A transmission mechanism is provided below the inclined groove. The transmission mechanism includes a dual-output shaft DC motor with symmetrically mounted transmission shafts on both sides of the dual-output shaft DC motor. Root and leaf rollers are installed at the ends of the transmission shafts on both sides. The root and leaf rollers are located at the openings on both sides of the inclined groove and extend beyond the bottom surface of the openings. A pressure cylinder is also installed between the openings on both sides. The pressure cylinder limits the position of the scallion to be removed, preventing the scallion from shifting during the removal of roots and leaves and ensuring that the roots and leaves of the scallion are completely removed.

[0007] A baffle plate is installed between the two sides of the inclined groove. The baffle plate is arranged parallel to the direction in which the scallion is placed, and the two ends of the baffle plate are fixed to the inclined groove by the first wedge block.

[0008] The peeling unit includes a conveying mechanism and a peeling mechanism. The conveying mechanism includes a moving trough and a fixed trough. The two sides of the moving trough are rotatably connected to the two sides of the fixed trough. A set of idlers is connected between the two sides of the fixed trough. The peeling mechanism is located above the idlers. The peeling mechanism includes a roller brush. The roller brush is located directly above the idlers. The two sides of the roller brush are connected to the sides of the moving trough through sliding components. During the process, the brush moves upward and during the return process, the brush moves downward, thereby peeling the scallions held between the idlers.

[0009] The upper surfaces of both the moving groove and the fixed groove are provided with multiple grooves for placing scallions. The two sides of the moving groove near the root and leaf unit are each equipped with a second wedge. The second wedge contacts and engages with the first wedge. The engagement of the second wedge with the first wedge enables the opening and closing of the baffle, allowing the scallions to fall sequentially into the conveying mechanism of the peeling unit.

[0010] The segmentation unit includes a trapezoidal inclined groove, with a baffle above the trapezoidal inclined groove. One end of the baffle is fixed to both sides of the trapezoidal inclined groove, and the other end is located at the end of the conveying mechanism of the peeling unit. A conveying shaft is located below the trapezoidal inclined groove, and at least two segmenting rollers are installed at intervals on the conveying shaft. Each segmenting roller extends out of the upper surface of the trapezoidal inclined groove for segmenting the scallions.

[0011] A segmented pressure cylinder is installed below the baffle. The two sides of the segmented pressure cylinder are fixed to the two sides of the trapezoidal inclined groove. The segmented pressure cylinder and the segmented roller are staggered. The segmented pressure cylinder presses down on the scallion to be segmented to prevent the scallion from shifting during the segmentation process and to ensure that the segmentation is carried out smoothly.

[0012] The weighing unit includes a throwing mechanism and a conveyor belt. A packing box is located above the conveyor belt, and a swing support shaft is located below the conveyor belt. The swing support shaft is arranged along the width of the conveyor belt and close to the front end of the conveyor belt. Under the action of the lever arm, the conveyor belt is initially inclined, with the front end of the conveyor belt higher than the rear end. Limiting devices are provided on both the upper and lower sides of the rear end of the conveyor belt. A mercury switch is provided on the side of the conveyor belt. When the scallions in the packing box reach a certain weight, the conveyor belt tilts at a certain angle under the constraint of the limiting devices, triggering the mercury switch, starting the conveyor belt, and conveying the packing box to the packaging unit.

[0013] The packaging unit includes a pair of upper rotating shafts connected by a synchronous belt. Each upper rotating shaft has a lower rotating shaft below it. A plastic wrap is fitted between the upper and lower rotating shafts. An upper plate is located below the synchronous belt. A film-cutting blade is connected to the lower part of the upper plate. The two sides of the film-cutting blade are connected to the upper plate by springs. A cam mechanism is provided between the top of the film-cutting blade and the upper plate. A sponge is placed in the groove of the film-cutting blade. The sponge extends 5-8 mm beyond the film-cutting blade. During the pressing process, the sponge contacts and presses the plastic wrap first.

[0014] Beneficial effects: This utility model integrates root removal, peeling, segmentation, and packaging into one integrated process, with each step complementing the others. The automated equipment can operate in an orderly manner without being restricted by manual labor, improving the standardization and efficiency of scallion processing. It effectively solves the drawbacks of low efficiency and high cost caused by multiple machines processing scallions together. The vertical structure requires less space, and the layer-by-layer process allows for a natural transition in slope between layers, resulting in smooth connections. This effectively eliminates the large footprint of traditional planar mechanical processing. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figures 1-9 As shown, the vertical scallion cleaning, weighing, and packaging integrated machine of this utility model includes a first layer device and a second layer device, which are supported by a surrounding support frame. The first layer device includes a root and leaf unit 1, a peeling unit 2, and a segmenting unit 3. The second layer device includes a weighing unit 4 and a packaging unit 5. The peeling unit 2 has the root and leaf unit 1 at one end and the segmenting unit 3 at the other end. The weighing unit 4 is located diagonally below the segmenting unit 3, and the packaging unit 5 is located above the weighing unit 4.

[0026] like Figure 2 , Figure 4 and Figure 5 As shown, the root and leaf unit 1 includes an inclined groove 101, which is inclined at 30-45°. The inclined groove 101 has symmetrical openings on both sides of its front end. A scallion is placed between these openings. A transmission mechanism is located below the inclined groove 101, including a dual-output shaft DC motor 105. Conveyor shafts are symmetrically mounted on both sides of the dual-output shaft DC motor 105, and root and leaf rollers 102 are mounted at the ends of both conveyor shafts. The root and leaf rollers 102 are located at the openings on both sides of the inclined groove 101 and extend below the openings. The root and leaf rollers 102 remove the roots and leaves from the scallions placed on the inclined groove 101. A pressure cylinder 106 is also installed between the openings on both sides. The pressure cylinder 106 limits the position of the scallion to be derooted, preventing displacement during the root and leaf removal process and ensuring complete removal of the roots and leaves. A baffle plate 103 is also installed between the two sides of the inclined groove 101. The baffle plate 103 is arranged parallel to the direction in which the scallion is placed. Both ends of the baffle plate 103 are fixed to the inclined groove 101 by the first wedge block 104.

[0027] like Figure 2 , Figure 6 and Figure 7 As shown, the peeling unit 2 includes a conveying mechanism and a peeling mechanism. The conveying mechanism includes a moving groove 201 and a fixed groove 202. The two sides of the moving groove 201 are respectively connected to the two sides of the fixed groove 202 via cranks. The moving groove 201 is driven by a stepper motor 205. A set of idler rollers 204 are connected between the two fixed grooves 202. The idler rollers 204 are placed side by side in the middle of the fixed grooves 202, and the scallions can be clamped between the idler rollers 204. A peeling mechanism is provided above the idler rollers 204. The peeling mechanism includes a roller brush 206. The roller brush 206 is located directly above the idler rollers 204. The two sides of the roller brush 206 are connected to the linear bearings in the sliding assembly 207 via a cross-shaped fixing bracket with bearings. The other end of the sliding assembly 207 is connected to the side of the moving groove 201 via a connecting rod. During the process, the brush moves upward (to avoid misalignment). During the return process, the brush has moved downward, thereby peeling the scallions clamped between the idler rollers 204.

[0028] The upper surfaces of the moving groove 201 and the fixed groove 202 are provided with multiple semi-circular grooves at intervals, and scallions can be placed between the semi-circular grooves on both sides; the moving groove 201 is equipped with a second wedge 203 on both sides near the root leaf unit 1. The second wedge 203 contacts and cooperates with the first wedge 104. The opening and closing of the baffle 103 is realized through the cooperation of the second wedge 203 and the first wedge 104, so that the scallions fall into the conveying mechanism of the peeling unit 2 in sequence. The rotating trough 201 drives the second wedge block 203 to lift the first wedge block 104, which in turn drives the baffle 103 to open, so that only one scallion enters the semi-circular groove of the fixed trough 202 at a time. When the rotating trough 201 rotates once, it transports the scallion in the previous groove of the fixed trough 202 to the next groove. The above movement is repeated, and the scallions are arranged in sequence in the groove of the fixed trough 202. When the scallion is transported to the top of the idler roller 204, the rotating trough 201 just rotates to the lowest point and stops rotating. At the same time, the roller brush 206 contacts the scallion under the action of the connecting rod to peel it. After peeling, the rotating trough 201 continues to rotate and repeats the above peeling operation. The peeled scallion continues to be transported by the rotating trough 201 to one side of the segment unit 3.

[0029] like Figure 2 , Figure 8 As shown, the segmentation unit 3 includes a trapezoidal inclined chute 302, a baffle 301, and segmenting roller cutters 303. The trapezoidal inclined chute 302 is inclined at 30-45° and has a small protrusion at its end. The baffle 301 is located above the trapezoidal inclined chute 302. One end of the baffle 301 is fixed to both sides of the trapezoidal inclined chute 302, and the other end is located at the end of the conveying mechanism of the peeling unit 2. The baffle 301 stops the scallions transported by the peeling unit 2 and causes them to fall into the second layer device. A conveyor shaft is located below the trapezoidal inclined chute 302. One end of the conveyor shaft is connected to a motor. At least two segmenting roller cutters 303 are installed at intervals on the conveyor shaft. Each segmenting roller cutter 303 extends out of the upper surface of the trapezoidal inclined chute 302 for segmenting the scallions. The segmented scallions are arranged at the small protrusion at the bottom of the trapezoidal inclined chute 302, awaiting further processing. A segmented pressure cylinder 304 is also installed below the baffle 301. The two sides of the segmented pressure cylinder 304 are fixed to the two sides of the trapezoidal inclined groove 302 respectively. The segmented pressure cylinder 304 and the segmented roller cutter 303 are staggered. The segmented pressure cylinder 304 presses down the scallion to be segmented to prevent the scallion from shifting during the segmentation process and ensure that the segmentation is carried out smoothly.

[0030] like Figure 3As shown, the weighing unit 4 includes a throwing mechanism 401 and a conveyor belt 402. The throwing mechanism 401 is driven by a motor and uses a crank and multiple connecting rods to precisely pick up and throw the segmented scallions, arranging them neatly from the trapezoidal chute 302 into a packing box 403 above the conveyor belt 402. The packing box 403 is placed on the conveyor belt 402 near the side of the throwing mechanism 401. A swing support shaft 404 is provided below the conveyor belt 402. The swing support shaft 404 is arranged along the width of the conveyor belt 402 and is close to the front end of the conveyor belt 402. The entire conveyor belt 402 can swing freely around the swing support shaft 404. Under the action of the lever arm, the conveyor belt 402 is initially inclined, with the front end of the conveyor belt 402 higher than the rear end. Limiting devices 405 are provided on both the upper and lower sides of the rear end of the conveyor belt 402 to ensure that the conveyor belt 402 swings at a small angle each time. A mercury switch 406 is provided on the side of the conveyor belt 402. When the green onions in the packaging box 403 reach a certain weight, the conveyor belt 402 tilts at a certain angle under the constraint of the limiting device 405, triggering the mercury switch 406, starting the conveyor belt 402, and conveying the packaging box 403 to the packaging unit 5.

[0031] like Figure 9 As shown, the packaging unit 5 is located above the rear end of the conveyor belt 402. The packaging unit 5 includes a pair of upper rotating shafts 507 connected by a synchronous belt 506 for spreading and retracting the plastic wrap. One of the upper rotating shafts 507 is connected to a motor. Each upper rotating shaft 507 has a lower rotating shaft 508 below it. Plastic wrap 501 is fitted between the upper rotating shaft 507 and the lower rotating shaft 508. An upper plate 509 is located below the synchronous belt 506. A film-cutting blade 505 is connected below the upper plate 509. The two sides of the film-cutting blade 505 are connected to the upper plate 509 by springs 503. A cam mechanism 502 is provided between the top of the film-cutting blade 505 and the upper plate 509. A square groove is provided on the upper plate 509 at the position corresponding to the cam to ensure that the cam mechanism 502 can rotate normally without interference. The cam mechanism 502 and the spring 503 drive the film cutting blade 505 to move up and down to achieve sealing. When the cam mechanism 502 returns, the film cutting blade 505 can rise synchronously. The inner groove of the film cutting blade 505 is filled with a sponge 504. The sponge 504 extends 5~8mm beyond the film cutting blade 505. During the downward pressing process, the sponge 504 contacts and presses the plastic wrap 501 first.

[0032] Working principle: Scallions are placed into the inclined groove 101 in the root and leaf unit 1. They fall under their own weight and, constrained by the pressure cylinder 106, are derooted and defoliated by the root-and-leaf removal roller 102 at the bottom of the groove, then neatly collected at the baffle 103. When the stepper motor 205 is turned on, the moving groove 201 in the peeling unit 2 rotates, causing the second wedge 203 at the front end to lift the first wedge 104, which in turn causes the baffle 103 to open, ensuring that only one scallion enters the semi-circular groove of the fixed groove 202 at a time. As the moving groove 201 rotates... The scallions are moved from the previous groove to the next groove in the fixed groove 202 in one rotation. This process is repeated until the scallions are arranged one by one in the grooves of the fixed groove 202. When the scallions are directly above the idler roller 204, the moving groove 201 has just reached its lowest point and stops rotating. At the same time, the roller brush 206, under the action of the connecting rod, contacts the scallions to peel them. After peeling, the moving groove 201 continues to rotate and repeats the peeling operation. Meanwhile, the peeled scallions continue to be transported by the rotating moving groove 201 to the stop. On one side of plate 301, blocked by baffle 301, the scallions enter segmentation unit 3; constrained by segmentation pressure cylinder 304, segmentation cutter 303 below trapezoidal chute 302 divides the scallions into three segments, and the segmented scallions are arranged on one side of trapezoidal chute 302 awaiting further operation; the throwing mechanism 401 of weighing unit 4 transports the segmented scallions one by one into packaging box 403. When the scallions in the packaging box reach a certain weight, the conveyor belt 402 tilts at a certain angle under the constraint of limit device 405, triggering... Mercury switch 406 starts the conveyor belt 402 to rotate, transporting the packaging box 403 to the bottom of the packaging unit 5 and stopping. The plastic wrap 501 unfolds and tightens with the cooperation of the upper rotating shaft 507 and the lower rotating shaft 508. The cam mechanism 502 presses down the cutting blade 505 and the sponge 504. The sponge 504 first contacts the plastic wrap 501 and presses it onto the packaging box 403. Then the cutting blade 505 cuts the plastic wrap. Finally, the spring 503 lifts the cutting blade 505 and the sponge 504 to complete the packaging.
