Description

Technical Field

[0001] This invention relates to the field of scallion processing technology, and in particular to an integrated machine for washing and bundling scallions. Background Technology

[0002] As a vegetable, the post-harvest processing of scallions directly determines their circulation quality and market value.

[0003] The applicant's known scallion processing technologies include manual processing and equipment processing. Manual processing involves manually removing the roots and yellow leaves from each scallion, as well as manual washing and packaging. This process is time-consuming and inefficient. Furthermore, uneven application of force during manual processing can lead to uneven damage to the scallion's skin, making it prone to injury. Equipment processing mainly utilizes equipment to replace manual labor. For example, cutting equipment removes roots and yellow leaves, spraying equipment works with brushes to clean the soil adhering to the bottom of the scallions, and baling machines bundle them. However, the lack of a linkage mechanism between multiple devices means that manual labor is required to transfer the scallions between the cutting equipment, spraying equipment, and baling machines, resulting in low efficiency. Moreover, during the cutting and spraying process, the scallions are mostly cut and cleaned by tilting, and the cutting and cleaning forces can easily cause the scallions to change their posture, thus affecting the cutting and cleaning effects.

[0004] Therefore, there is an urgent need for a scallion washing and bundling machine that has high processing efficiency and good processing effect. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated machine for washing and bundling scallions, so as to solve the problems existing in the prior art. The integrated design reduces manual intervention and improves processing efficiency. At the same time, the clamping and conveying can effectively ensure the posture of the scallions, thereby improving the processing effect of scallions.

[0006] To achieve the above objectives, the present invention provides the following solution: The present invention provides a scallion washing and bundling integrated machine, comprising: A vertical conveying mechanism is used for vertically conveying scallions.

[0007] Preferably, the cutting mechanism includes a motor and a cutting blade, the motor and the cutting blade are connected in a transmission connection, and the cutting blade is set on the conveying path of the scallion.

[0008] Preferably, the cutting mechanism further includes a hair dryer, which is positioned corresponding to the top yellow leaf area of ​​the scallion, so as to blow away the yellow leaves after the cutting blade cuts off the yellow leaves.

[0009] Preferably, the cutting mechanism further includes a waste collection channel, the inlet of which is set to correspond to the path of yellow leaves being blown away and the path of roots falling off, and the outlet of which is connected to the external space of the machine.

[0010] Preferably, the cleaning mechanism includes multiple cleaning units arranged sequentially along the scallion conveying path. Each cleaning unit includes a brush and a spray head, the spray head being connected to a water supply unit. Both the brush and the spray head are arranged corresponding to the scallion conveying path to clean the surface of the scallions.

[0011] Preferably, along the conveying path of the scallions, the hardness of the brushes of the multiple cleaning units gradually decreases.

[0012] Preferably, the cleaning mechanism further includes a water circulation system, which includes a collection hood, a water tank, a filter device, and a water pump. The collection hood is located below the vertical conveying mechanism to collect spray water. The collection hood is connected to the water tank, and the water tank is connected to the spray head through the water pump. The filter device is located between the collection hood and the water tank and / or between the water pump and the spray head.

[0013] Preferably, the scallion washing and bundling integrated machine further includes a guiding and gathering mechanism, which is disposed between the washing mechanism and the bundling mechanism. The guiding and gathering mechanism includes an isolation rod and a gathering frame. The isolation rod is disposed at the end of the conveyor belt to guide the scallions to fall onto the gathering frame, and the gathering frame collects multiple fallen scallions.

[0014] Preferably, a weighing device is provided at the bottom of the gathering frame.

[0021] 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.

[0022] The purpose of this invention is to provide an integrated machine for washing and bundling scallions to solve the problems existing in the prior art. The integrated design reduces manual intervention and improves processing efficiency. At the same time, the clamping and conveying can effectively ensure the posture of the scallions, thereby improving the processing effect of scallions.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Please refer to the following: Figures 1-8As shown, a scallion washing and bundling integrated machine is provided, including: a vertical conveying mechanism, a cutting mechanism, a washing mechanism, and a bundling mechanism 22. The vertical conveying mechanism is used for vertically conveying scallions; the cutting mechanism is used for cutting the top yellow leaf area and root area of ​​the scallions; the washing mechanism is used for washing the scallions; and the bundling mechanism 22 is used for bundling batches of scallions. The vertical conveying mechanism includes a clamping conveyor belt and vertical holding rollers. The vertical holding rollers include a vertically arranged rotating shaft 2 and limiting plates 3. Multiple limiting plates 3 are evenly arranged around the rotating shaft 2 in a circumferential direction, forming multiple vertical limiting spaces. The rotating shaft 2 and limiting plates 3 are only a basic configuration; the shape of the rotating shaft 2 can be changed as needed. For example, the structure can be changed to a ring shape so that it can rotate around its own axis. The limiting plate 3 can also be changed in shape as needed, for example, it can be changed to a strip protrusion so that it can rotate with the rotating shaft 2 and form a vertical limiting space between each pair. The clamping conveyor belt includes at least two oppositely arranged conveyor belts 1. A vertical channel for clamping and transporting scallions is formed between adjacent conveyor belts 1. The starting end of the vertical channel is set to correspond to the rotation path of the limiting space. The width of the vertical channel should be less than the diameter of the scallion to achieve clamping. The width of the vertical channel can be determined according to the diameter of the batch of scallions being processed. For example, if the diameter of the batch of scallions is about 2-3cm, the width of the vertical channel can be set to 1.For a 9cm conveyor belt 1, an elastic and deformable material, such as rubber, is preferred. This allows the conveyor belt 1 to utilize its deformation properties to minimize damage to large-diameter scallions during clamping. A limiting space is positioned at the center of the scallion, corresponding horizontally. When the scallion is held by hand or by a robotic arm (referring to a multi-degree-of-freedom robotic arm, as in existing transfer equipment), the limiting plate 3 can push the scallion from the center. At the entrance of the vertical channel, even if the scallion is tilted, its tilted front end will be blocked by the conveyor belt 1 before being transported. During this blocking process, the limiting plate 3 can push the scallion from the center using its vertical plane, transporting the tilted rear end of the scallion to the conveyor belt 1, thus reducing the tilt angle. The cutting and cleaning mechanisms are located on the scallion's clamping and transporting path. (Bundling machine) Mechanism 22 is located behind the clamping and conveying path of the scallions. When more than two conveyor belts 1 are set, the number of conveyor belts 1 should be even, with each pair forming a vertical channel. Multiple sets of conveyor belts 1 should be set from top to bottom, and the vertical channels of multiple sets of conveyor belts 1 should be correspondingly set. This equipment integrates a vertical conveying mechanism, a cutting mechanism, a washing mechanism, and a bundling mechanism 22. Cutting and washing are completed simultaneously during the conveying process, reducing manual intervention and improving processing efficiency. In addition, the vertical limiting space formed by the circumferentially distributed limiting plates 3, in conjunction with the conveyor belts 1, corrects the posture of the scallions. The conveyor belts 1 convey the scallions by clamping, and the clamping force ensures that the posture of the scallions does not change during subsequent conveying. This allows the subsequent cutting and washing mechanisms to remove roots, yellow leaves, and clean the scallions at preset positions and directions, improving the processing effect of the scallions.

[0025] When a single conveyor belt 1 is set up, it should be equipped with a driving roller and a driven roller. The conveyor belt 1 is fitted on the driving roller and the driven roller. The driving roller is connected to the drive motor. The driving rollers of two conveyor belts 1 that form a vertical channel can be connected (e.g., gear transmission) and driven by a drive motor, or they can each be connected to a drive motor.

[0026] The end face of the conveyor belt 1 near the vertical channel and the end face of the limiting plate 3 can be coated with polytetrafluoroethylene to reduce damage to the scallions. Of course, other structures that can reduce damage to the scallions can also be selected, such as flexible rubber pads. When the conveyor belt 1 is made of rubber, the rubber pads can be omitted.

[0027] The conveyor belt 1 is also equipped with a tensioning mechanism, which includes a roller 4, a connecting rod 5, and a tension spring 6. The roller 4 is rotatably connected to one end of the connecting rod 5, and the middle part of the connecting rod 5 is rotatably mounted on the frame. Specifically, a connecting base 7 can be set on the frame. The connecting base 7 is T-shaped, and its extended end is rotatably connected to the connecting rod 5 through a rotating shaft. The end of the connecting rod 5 away from the roller 4 is connected to the frame through the tension spring 6. The tension spring 6 uses tension to ensure that the roller 4 is attached to the inner wall of the conveyor belt 1. Multiple tensioning mechanisms can be set to ensure the normal conveying of the conveyor belt 1. The tension spring 6 in the tensioning mechanism also provides deformable compensation for the conveyor belt 1. When the diameter of the scallion is large, it will cause deformation of the conveyor belt 1 at the position corresponding to the scallion. This deformation can cause the tension spring 6 to deform, thereby causing the roller 4 to change position. This avoids the problem of the conveyor belt 1 causing hard squeezing of the scallion when the position of the roller 4 cannot change.

[0028] Since the roller 4 rotates when it comes into contact with the conveyor belt 1, the rotating shaft 2 of the vertically holding roller can be connected to the roller 4, that is, the roller 4 drives the rotating shaft 2 to rotate, which can save the need for a motor to drive the rotating shaft 2.

[0029] The connecting rod 5 of the tensioning mechanism located outside the conveyor belt 1 is rotatably connected at one end to the connecting base 7 and at the other end to the roller 4. The roller 4 is located outside the conveyor belt 1. The connecting rod 5 is then connected to the frame through the tension spring 6. In this way, tensioning is controlled from the outside by ballast.

[0030] The cutting mechanism includes a motor and a cutting blade 8. The motor and the cutting blade 8 are connected by a drive. The cutting blade 8 is set on the conveying path of the scallion. Specifically, at least two cutting blades 8 should be set, one for cutting the root and the other for cutting the yellow leaves. The cutting blade 8 is offset from the conveyor belt 1 so that the two do not interfere with each other. The cutting blade 8 is made of stainless steel. When multiple cutting blades 8 are set, they should be arranged along the conveying path of the scallion. Multiple cutting blades 8 corresponding to the root or top yellow leaf part can be on the same horizontal plane. Through multiple cuts, it is ensured that the cut is complete and no uncut parts remain.

[0031] An automatic detection system can be designed upstream of the cutting position of the cutting blade 8, that is, upstream of the cutting area of ​​the cutting blade 8 in the scallion conveying path. For example, a camera can be installed on the frame to capture the overall posture of the scallion being conveyed and its position relative to the reference object (frame). The system can then identify the length of the yellow leaves and the length of the roots. In addition, a linear drive mechanism (such as a ball screw mechanism or telescopic cylinder) can be set to drive the vertical movement of the cutting blade 8. At this time, the system can control the vertical position of the cutting blade 8 through the linear drive mechanism to accurately cut the yellow leaves and roots of the current scallion, effectively improving the removal effect of yellow leaves and roots.

[0032] The cutting mechanism also includes a blower 9, which is set to the top yellow leaf area of ​​the scallion. After the cutting blade 8 cuts off the yellow leaves, the blower 9 blows the yellow leaves away to prevent them from moving to the rear with the conveyor belt 1 and affecting the subsequent bundling work. The blower 9 can be directly set on the frame, and the blower 9 supplies airflow to the conveying path of the yellow leaves in the form of oblique or side air.

[0033] The cutting mechanism also includes a waste collection channel. The inlet of the waste collection channel is set to correspond to the path of the yellow leaves being blown away and the path of the roots falling. The outlet of the waste collection channel is connected to the external space of the machine so as to discharge the cut yellow leaves and roots outside the machine. Specifically, a funnel-shaped collection channel can be wrapped around the cutting position. The funnel-shaped collection channel needs to be equipped with a corresponding avoidance opening to avoid the normal conveyor belt 1 and the normal transport of the green onions. The funnel-shaped collection channel can complete the waste collection work. The small end of the funnel-shaped collection channel can be directly led to the external space through the inclined channel. An additional collection container can be designed to collect the cut yellow leaves and roots; or the frame can be set as an exposed frame structure, so that the roots and yellow leaves can be discharged directly from the gaps in the frame and collected later.

[0034] The cleaning mechanism includes multiple cleaning units, which are arranged sequentially along the scallion conveying path. Each cleaning unit includes a brush 10 and a spray head 11. The spray head 11 is connected to the water supply unit. Both the brush 10 and the spray head 11 are arranged according to the scallion conveying path. The brush 10, in conjunction with the spray water, can improve the removal effect of the attached sludge.

[0035] When multiple tensioning mechanisms are set, several tensioning mechanisms can be set on both sides of the conveying path of the scallion. In this way, the brush 10 can be directly set below the roller 4 based on the design of the roller 4 (for example, the shaft of the roller 4 is connected to the brush 10). Of course, the brush 10 can be set independently by connecting it to the frame through the connector.

[0036] Based on the brush 10, an additional drive motor can be set to drive the brush 10. The rotation direction of the brush 10 is opposite to the conveying direction of the scallions to improve the cleaning effect. When the brush 10 is set on the roller 4, the drive motor can be set on the fixed central shaft of the roller 4. When the brush 10 is connected to the connector, the drive motor can be directly set on the connector.

[0037] The position of the spray head 11 can be determined as needed. In this embodiment, there are two sets of conveyor belts 1, which respectively clamp the upper and lower parts of the scallion. The spray head 11 is located above the upper set of conveyor belts 1 and in the middle of the two sets of conveyor belts 1, which can provide a good cleaning effect.

[0038] The spray head 11 is an adjustable angle spray head 11, which makes it easy to adjust the direction of the spray head 11 as needed to improve the cleaning effect on the green onions. Of course, the direction of the spray head 11 can also be adjusted by the system to improve the degree of automation.

[0039] Along the conveying path of the scallions, the hardness of the brushes 10 in multiple cleaning units gradually decreases, which can ensure the cleaning effect while avoiding excessive damage to the scallions.

[0040] Multiple spray heads 11 can be set in the cleaning unit to improve the cleaning effect.

[0041] An automatic detection system can be installed upstream of each cleaning unit, that is, upstream of the cleaning area corresponding to the scallion conveying path. Specifically, a camera is used to capture images of the scallion surface and transmit the images to the system to analyze the cleanliness of the scallions. When the scallions are found to be dirty, the rotation speed of the downstream brush 10 and the spray volume and water pressure of the spray head 11 can be increased to improve the cleaning effect. When the scallions are found to be relatively clean, the rotation speed of the downstream brush 10 and the spray volume and water pressure of the spray head 11 can be reduced accordingly. When the scallions are found to be clean, the rotation of the downstream brush 10 and the spraying of the spray head 11 can be stopped, realizing automated control, improving the cleaning effect while saving energy.

[0042] In one embodiment, three cleaning units are provided. The first cleaning unit has a brush 10 made of nylon 66 with a filament diameter of 0.3 mm and a hardness of 55 Shore A. The roller has a diameter of 50 mm and a length of 300 mm. It is equipped with three umbrella-shaped spray heads 11 with a spray angle of 120° (the spray angle refers to the angle between the direction of the spray head 11 and the scallion). The water pressure is 0.3 MPa and the flow rate per head is 1.2 L / min. The mechanical friction of the hard brush 10 breaks down the stubborn soil adhering to the roots, and the soil removal rate reaches 97.5%. The second cleaning unit has a brush 10 made of nylon 66 + polyester blend with a filament diameter of 0.2 mm and a hardness of 40 Shore A. The roller parameters are the same as the first unit, and the rotation speed is 280 r / min. The water pressure of spray head 11 is reduced to 0.2 MPa and the flow rate is 1.0 L / min, focusing on rinsing away the residual sewage stains from the first stage. The main component is a mud suspension, and the sewage stain removal rate reaches 96.8%. The brush 10 of the third cleaning unit is made of soft polyester with a filament diameter of 0.15 mm, a hardness of 25 Shore A, and a rotation speed of 250 r / min to avoid scratching the surface of the onion. The water pressure of spray head 11 is further reduced to 0.15 MPa and the flow rate is 0.8 L / min. At the same time, the spray direction is at a 45° angle to the surface of the onion to reduce moisture residue. After the final cleaning, the residual moisture on the surface of the onion is ≤0.1 g / piece, which ensures the accuracy of subsequent weighing (weighing deviation ≤±5 g / bundle) and avoids moisture affecting the adhesive strength of the OPP strap. In this embodiment, a more refined cleaning unit design is provided, in which not only the hardness of the brush 10 gradually decreases, but the water spray pressure also gradually decreases, further improving the protection effect on the onion.

[0043] To avoid water waste, the cleaning system also includes a water circulation system, which comprises a collection hood, a water tank 12, a filter, and a water pump 14. The collection hood is located below the vertical conveying mechanism to collect spray water. The collection hood is connected to the water tank 12, which is connected to the spray head 11 via the water pump 14. The water pump 14 can be built into the water tank 12 or mounted on the frame. The filter is located between the collection hood and the water tank 12 and / or between the water pump 14 and the spray head 11, thus achieving water recycling. Simultaneously, the filter filters wastewater to ensure the cleanliness of the spray water. Water needs to be replenished to the water tank 12 periodically to ensure sufficient water supply. The filter is a conventional device and will not be described in detail here. A perforated plate 13 can be installed at the top collection port of the collection hood to prevent the cut scallion roots or yellow leaves from falling into the collection hood during the cutting process and blocking the subsequent water delivery path.

[0044] The scallion washing and bundling integrated machine also includes a guiding and gathering mechanism, which is located between the washing mechanism and the bundling mechanism 22. The guiding and gathering mechanism includes an isolation rod 15 and a gathering frame. The isolation rod 15 is located at the end of the conveyor belt 1 and guides the scallions to fall onto the gathering frame. The gathering frame collects multiple fallen scallions.

[0045] The specific design scheme of the isolation rod 15 is as follows: the isolation rod 15 is set on the conveying path corresponding to the bottom of the scallion, and the isolation rod 15 is perpendicular to the conveying path of the scallion. The principle of this design is: during the process of the scallion being conveyed, when it moves to the position of the isolation rod 15, the bottom of the scallion first contacts the isolation rod 15 and is blocked by the isolation rod 15. At this time, the top of the scallion is conveyed normally, and the bottom is blocked, so that the scallion overcomes the friction of the conveyor belt 1 and produces a forward tilting action until the bottom of the scallion is no longer blocked by the isolation rod 15, thus completing the adjustment of the scallion's posture. In this way, when the scallion leaves the conveyor belt 1 later, it will be sent out in a forward tilting posture and the top will tilt forward.

[0046] The specific design scheme of the collection frame is as follows: The collection frame includes a U-shaped collection plate 16 and a baffle 17. The baffle 17 is set at the top opening of the collection plate 16, and the middle part of the baffle 17 is set in a V shape. A strip hole is opened in the middle of the V shape for a single scallion to fall. When the scallion is tilted, it will first fall on the baffle 17. Guided by the V shape of the baffle 17, it will fall into the collection frame from the strip hole in the middle to complete the collection. The collection frame can also be set as a U-shaped structure to collect multiple tilted scallions.

[0047] The bottom of the inner cavity of the gathering plate 16 is a flat structure, which allows the collected scallions to be arranged with their bottoms flat. After being transferred to the bundling mechanism 22, the whole scallions can contact the work surface of the bundling mechanism 22 with a flat surface. Compared with the curved bottom or the conical bottom, this can avoid the problem of loosening on the work surface of the bundling mechanism 22 and improve the anti-loosening properties after bundling.

[0048] A weighing device is installed at the bottom of the gathering frame to obtain the weight of the green onions on the gathering frame in real time. When the weight of the green onions reaches the preset minimum weight of each bundle, the conveyor belt 1 is paused and the collected green onions are bundled for subsequent work.

[0049] The guiding and gathering mechanism also includes a pushing mechanism to push the scallions collected by the gathering rack to the bundling mechanism 22. The pushing mechanism mainly includes a first linear motion mechanism 18, a second linear motion mechanism 19, a moving part 20, and a push plate 21. The push plate 21 matches the inner cavity shape of the gathering rack to improve the pushing effect on the scallions. The second linear motion mechanism 19 is set on the moving end of the first linear motion mechanism 18. The movement directions of the first linear motion mechanism 18 and the second linear motion mechanism 19 are perpendicular to each other. The moving end of the second linear motion mechanism 19 is connected to the push plate 21 through the moving part 20. The first linear motion mechanism 18 and the second linear motion mechanism 19 can drive the push plate 21 to push the scallions on the gathering rack toward the bundling mechanism 22 for bundling, completing the automatic bundling work and improving the processing efficiency of scallions.

[0050] When the gathering frame includes a gathering plate 16 and a baffle 17, the movable part 20 is inverted U-shaped or L-shaped. During the process of driving the push plate 21 to push the scallion, the part of the movable part 20 connected to the push plate 21 needs to correspond to the strip hole. When the push plate 21 enters the gathering plate 16, this part is in the strip hole, that is, the strip hole serves as a clearance hole for this part to move. When the gathering frame is a U-shaped frame, the movable part 20 is also inverted U-shaped or L-shaped. The top opening of the gathering frame serves as a clearance hole to avoid the movement of the part of the movable part 20 connected to the push plate 21.

[0051] The first linear motion mechanism 18 and the second linear motion mechanism 19 can be selected from mechanisms that generate linear motion, such as electric telescopic cylinders and ball screw transmission mechanisms, and the specific selection can be made according to the needs.

[0052] The bundling mechanism 22 can be a commercially available bundling machine, which is a standard piece of equipment and will not be described in detail here.

[0053] In actual use, a person or a robotic arm places the scallions from the side of the machine between the vertical retaining rollers and the limiting plates 3. The rotating shaft 2 rotates, driving the scallions into the transmission start of the conveyor belt 1. The conveyor belt 1 moves the scallions by clamping them. During the clamping and conveying process, the scallions first pass through the cutting mechanism, where the cutting blade 8 rotates to remove the roots and top yellow leaves of the scallions. Then, they pass through multiple cleaning units, where brushes 10 and spray heads 11 clean the mud attached to the bottom of the scallions. Finally, the scallions are conveyed to the end of the conveyor belt 1, where they are blocked and guided by the isolation rod 15 and dumped onto the gathering rack. When the weighing equipment weighs the scallions and the weight reaches the preset value... After each bundle reaches its minimum weight, the conveyor belt 1 stops, the second linear motion mechanism 19 extends, driving the pusher plate 21 to move between the gathering frame and the conveyor belt 1. Then, the first linear motion mechanism 18 extends, driving the pusher plate 21 towards the gathering frame, pushing the scallions on the gathering frame into the bundling mechanism 22. In the actual pushing process, the pushing is carried out in three steps, dividing the scallion extension direction into three sections. The first push pushes the first section into the bundling operation area of ​​the bundling mechanism 22. After bundling, the second section is pushed into the bundling operation area of ​​the bundling mechanism 22 for a second bundling. Finally, the third section is pushed into the bundling operation area of ​​the bundling mechanism 22 for a third bundling.
