Description

Technical Field

[0001] This utility model relates to the technical field of fresh cut flower grading equipment, and in particular to an automatic grading device for fresh cut flowers. Background Technology

[0002] Currently, the grading of cut flowers mainly relies on manual labor or semi-automated equipment. In existing technologies, the feeding methods for cut flowers are mostly manual, with flowers being fed directly into the grooves of the main feeder, or pushed into the main feeder by a cylinder after being clamped by two sets of annular belts. These methods have the following problems:

[0003] (1) Manual feeding is slow and cannot meet the needs of high-speed production lines;

[0004] (2) The cylinder pushing method is prone to jamming and damage when running at high speed;

[0005] (3) Most equipment lacks the function of removing leaves and thorns according to the length of the flower stalk, resulting in low grading efficiency and a lot of manual intervention.

[0006] Therefore, there is an urgent need for an automated device that can achieve high-speed feeding, precise grading, and online puncture removal. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an automatic grading device for cut flowers, which can solve the problems of low feeding efficiency, poor handover and lack of online de-thorning function in the existing technology.

[0008] The technical solution adopted by this utility model to solve its technical problem is: an automatic grading device for fresh cut flowers, including a flower transfer mechanism, a main carrier conveying mechanism, a visual inspection mechanism, a leaf removal mechanism and a compartmenting mechanism. The main carrier conveying mechanism transports the fresh cut flowers from the flower transfer mechanism to the visual inspection mechanism, the leaf removal mechanism and the compartmenting mechanism in sequence.

[0009] The main carrier conveying mechanism is equipped with a main carrier that supports fresh-cut flowers;

[0010] The handover and flower-laying mechanism includes a flower-laying frame, on which a drive wheel assembly, a driven wheel assembly, and an annular flower-laying assembly are mounted. The annular flower-laying assembly covers the outer ring of the drive wheel assembly and the driven wheel assembly, and the drive wheel assembly is located close to the main carrier.

[0011] The annular flower-feeding component includes a flower-feeding timing belt, on which several flower-feeding carriers are installed at equal intervals. The flower-feeding timing belt includes two parallel straight segments, with the two ends of the two straight segments connected by an arc segment. One of the arc segments is positioned close to the main line of the cut flower.

[0012] The flower-loading mechanism also includes a pushing component for pushing the cut flowers from the flower-loading carrier into the main carrier. The pushing component is installed on the flower-loading frame and is located at a position tangent to the movement direction of the annular flower-loading component and the main carrier, and is positioned below the flower-loading carrier.

[0013] By combining the ring-shaped flower-feeding component and the pusher component, the automated transfer of cut flowers from the auxiliary line to the main line is achieved, reducing manual intervention and improving efficiency. The pusher component is positioned below the flower-feeding carrier and tangential to the direction of movement of the main carrier, ensuring precise alignment of the cut flowers during delivery and preventing damage to the flowers. The ring-shaped design of the flower-feeding synchronization belt (straight segment + arc segment) optimizes the spatial layout, making the arc segment near the main line easy to transfer, resulting in a compact structure.

[0014] Furthermore, the pattern-attaching frame includes a central frame, with surrounding sealing plates on the outside. An upper frame is located above the sealing plates, and a lower frame is located below them. The upper frame has active and passive mounting slots along its length, and a timing belt support plate is provided on the upper frame to support the pattern-attaching timing belt. The timing belt support plate supports the straight section of the timing belt, preventing sagging or deviation and ensuring operational stability.

[0015] Furthermore, the drive wheel assembly includes a drive synchronizing wheel and a drive shaft, with the drive shaft passing through the drive synchronizing wheel. The upper end of the drive shaft is connected to the output end of the flower drive motor, and the lower end of the drive shaft is equipped with several flower stem levers, which are evenly distributed around the drive shaft. The flower stem levers rotate with the drive shaft, facilitating the movement of the flower stems, preventing blockages, and improving continuous operation capability.

[0016] Furthermore, the drive wheel assembly also includes a drive wheel flange, which is positioned above the drive synchronous pulley. The drive shaft passes through the drive wheel flange and connects to the upper drive motor; the drive wheel flange is mounted on the drive mounting slot. The drive wheel flange enhances the installation stability of the drive wheel assembly and reduces vibration and misalignment.

[0017] Furthermore, the timing belt support plate is positioned below the straight and arc sections of the upper timing belt.

[0018] Furthermore, the driven wheel assembly includes a driven synchronous wheel and a driven rotating shaft, with the driven rotating shaft passing through the driven synchronous wheel; a driven wheel flange is provided above the driven synchronous wheel, the driven wheel flange is sleeved on the outside of the driven rotating shaft, and the driven wheel flange is installed on the driven mounting groove.

[0019] Furthermore, the driven pulley assembly also includes a driven tensioning block for adjusting the position of the driven pulley assembly, the driven tensioning block being mounted on the side wall of the driven pulley flange. The driven tensioning block can fine-tune the position of the driven pulley, compensate for wear or slack in the timing belt, and maintain constant tension.

[0020] Furthermore, the annular flower-laying assembly also includes multiple flower-laying fixing blocks and multiple carrier connecting plates. The multiple flower-laying fixing blocks are equidistantly installed on the flower-laying synchronous belt. The rear end of the flower-laying carrier is pinned to the mounting hole of the flower-laying fixing block, the rear end of the carrier connecting plate is pinned to the mounting hole of the flower-laying fixing block, and the front end of the carrier connecting plate is pinned to the mounting hole in the middle of the flower-laying carrier. The flower-laying fixing blocks connected to the flower-laying carrier and the flower-laying fixing blocks connected to the rear end of the carrier connecting plate are distributed adjacent to each other.

[0021] The pin-connection design between the upper fixing block and the carrier connecting plate enables a flexible connection between the upper fixing block and the carrier, adapting to operation on curved sections of the synchronous belt. The distribution of adjacent fixing blocks optimizes load distribution and reduces stress at individual connection points.

[0022] Furthermore, the pushing assembly includes a pattern pushing cylinder, a pattern pushing plate is mounted on the push rod of the pattern pushing cylinder, and the pattern pushing cylinder is mounted on the pattern pushing machine frame via a pushing mounting plate.

[0023] Furthermore, both the host carrier and the flower-raising carrier are provided with flower-raising openings.

[0024] Furthermore, the host vehicle conveying mechanism includes a host frame assembly, on which the host vehicle conveying assembly is mounted;

[0025] The main unit frame assembly includes an upper main unit support frame and a lower main unit support frame arranged vertically. The upper main unit support frame has a main unit power mounting slot and a main unit driven mounting slot at its front and rear ends, respectively. The upper main unit support frame has main unit timing belt support plates on both sides. The main unit carrier conveying assembly is installed on the upper main unit support frame. The main unit carrier conveying assembly includes a main unit drive wheel assembly, a main unit driven wheel assembly, a main unit timing belt, and a main unit carrier. The main unit drive wheel assembly is installed in the main unit power mounting slot of the upper main unit support frame. The main unit driven wheel assembly is installed in the main unit driven mounting slot of the upper main unit support frame. The main unit timing belt is installed around the outer ring of the main unit drive wheel assembly and the main unit driven wheel assembly. The main unit carriers are installed at equal intervals around the outer ring of the main unit timing belt, and the main unit carriers are arranged in a ring. The main unit timing belt support plates that support the main unit timing belt are installed on the upper main unit support frame.

[0026] Furthermore, the visual inspection mechanism is located at the end of the main carrier conveying mechanism and is positioned away from the handover and loading mechanism; the visual inspection mechanism includes a visual inspection support frame, on which a top inspection component and a surrounding inspection component are mounted.

[0027] The top detection component includes a first top light source, a second top light source, and a top camera. The top camera is installed directly above the spout on the main unit carrier, and the first and second top light sources are symmetrically installed on both sides of the top camera. The four-sided detection component includes a first four-sided light source, a second four-sided light source, a third four-sided light source, and a fourth four-sided light source arranged in a circle with the spout on the main unit carrier as the center.

[0028] Furthermore, the leaf-removing mechanism includes a leaf-removing frame, on which are provided a stem-clamping component for clamping the stems of fresh-cut flowers, a leaf-removing component for performing online leaf-removing actions in the direction of movement of the fresh-cut flowers, and a horizontal waste discharge line for collecting waste branches and leaves; the stem-clamping component, the leaf-removing component, and the horizontal waste discharge line are arranged from top to bottom, and the outlet of the horizontal waste discharge line is connected to a lifting waste discharge line;

[0029] The leaf-beating assembly includes a leaf-beating motion assembly installed on the leaf-beating machine frame, and a leaf-beating gripper assembly is installed on the moving end of the leaf-beating motion assembly.

[0030] The leaf-beating motion assembly includes an inclined linear motion module. The upper and lower ends of the linear motion module are mounted on the leaf-beating frame via an upper mounting base and a lower mounting base, respectively. A motion motor that drives the linear motion module is located on the outside of the linear motion module. A motion mounting base is provided on the slider of the linear motion module, and the leaf-beating gripper assembly is mounted on the motion mounting base.

[0031] The stem clamping assembly, leaf-removing gripper assembly, and waste removal flow line are arranged from top to bottom, conforming to the fresh-cut flower processing flow and improving space utilization. The stem clamping assembly secures the flower stems, while the leaf-removing gripper assembly automatically removes leaves, reducing manual intervention and increasing efficiency. The horizontal waste removal flow line, in conjunction with the lifting waste removal flow line, enables continuous cleaning of waste branches and leaves, preventing accumulation. The leaf-removing motion assembly uses an inclined linear module, which better conforms to the natural shape of the flower stem, resulting in more precise leaf removal and reduced damage.

[0032] Furthermore, the leaf-beating gripper assembly includes several gripper unit assemblies arranged side by side;

[0033] Each of the gripper unit assemblies includes a blade-beating linear guide pair and a blade-beating telescopic cylinder. The guide rail of the blade-beating linear guide pair is mounted on a motion mounting base, and the cylinder body of the blade-beating telescopic cylinder is connected to the guide rail of the blade-beating linear guide pair. A gripper mounting plate is mounted on the slider of the blade-beating linear guide pair, and the gripper mounting plate is connected to the push rod of the blade-beating telescopic cylinder.

[0034] The gripper mounting plate is equipped with a first gripper and a second gripper, which are connected by a gripper shaft. The gripper mounting plate is also equipped with a first gripper cylinder that drives the first gripper to rotate and a second gripper cylinder that drives the second gripper to rotate.

[0035] The leaf-removing gripper assembly features a modular design with multiple gripper units arranged side-by-side, allowing for the simultaneous processing of multiple cut flowers and improving efficiency. A linear guide rail and a telescopic cylinder work together to ensure stable gripper movement, preventing slippage or misalignment. The first and second grippers are independently driven by cylinders, flexibly adapting to flower stems of varying thicknesses and avoiding damage to the stems.

[0036] Furthermore, a gripper beam is mounted on the motion mounting base, and a blade-beating base plate is mounted on the guide rail of each blade-beating linear guide pair. The blade-beating base plate is connected to the gripper beam. The gripper beam and blade-beating base plate reinforce the gripper unit, preventing vibration or displacement and improving blade-beating accuracy.

[0037] Furthermore, both the horizontal waste discharge line and the vertical waste discharge line are equipped with belts for conveying waste branches and leaves. The belt design ensures smooth transport of branches and leaves, avoids blockages, and is suitable for continuous operation.

[0038] Furthermore, the stem clamping assembly includes two sets of stem clamping unit assemblies, which are arranged side by side and clamp and synchronously transport the fresh-cut flower stems; each stem clamping unit assembly includes a stem clamping belt, one end of which is equipped with a stem clamping drive wheel, and the other end of which is equipped with a stem clamping driven wheel, and the stem clamping drive wheel is connected to a stem clamping motor;

[0039] The stalk clamping unit assembly also includes a stalk clamping support plate, a stalk clamping belt is provided on the outside of the stalk clamping support plate, and a number of stalk clamping mounting plates are provided on the stalk clamping support plate. The stalk clamping unit assembly is connected to the leaf-cutting machine frame through the stalk clamping mounting plates.

[0040] The double-belt clamping system uses two sets of clamping units facing each other to hold the flower stems evenly, preventing them from bending or breaking. It features a drive pulley, a driven pulley, and a clamping motor, ensuring stable belt drive and, in conjunction with motor control, achieving uniform feeding of the flower stems.

[0041] Furthermore, the stem clamping support plate is provided with a gap adjustment seat for adjusting the position of the stem clamping belts. Adjusting the position of the gap adjustment seat makes the gap between the two stem clamping belts adjustable, which is convenient for accommodating flower stems of different diameters, has strong compatibility, and avoids slippage or damage caused by being too tight or too loose.

[0042] Furthermore, the clamping belt is a foam synchronous belt. The foam synchronous belt combines friction and elasticity, protecting the surface of the flower stem and reducing mechanical damage.

[0043] Furthermore, the stem clamping assembly has a guide plate at its discharge end to guide the cut flowers. The guide plate ensures the stability of the cut flowers during discharge, preventing collisions or tilting.

[0044] Furthermore, a tension adjustment plate is installed on the lower surface of the clamp support plate, and the tension adjustment plate is connected to the driven pulley of the clamp. The position of the driven pulley is adjusted by adjusting the plate to maintain stable belt tension and extend service life.

[0045] Furthermore, the clamping unit assembly also includes a support wear-resistant strip, which is mounted on one of the clamping support plates and located below the spout on the main carrier. The support wear-resistant strip supports the main carrier and prevents it from sagging or shifting when subjected to the blade striking force.

[0046] Furthermore, the compartmenting mechanism includes a compartmenting pusher assembly and at least one compartmenting flow channel module. The compartmenting pusher assembly is installed on the main line frame and located below the main line carrier. The compartmenting pusher assembly pushes the cut flowers from the main line carrier into the compartmenting flow channel.

[0047] The compartment flow channel module includes a compartment frame, on which several compartment flow channels are installed. Each compartment flow channel includes an inclined section and a horizontal section. The inclined section is set at an angle, with its high end located at the discharge end of the main fresh-cut flower sorting line, and its low end connected to the horizontal section. A rubber strip is provided on the part of the compartment flow channel that contacts the flower stem, and the rubber strip is covered with nylon cloth.

[0048] Equipped with compartmentalized feeding components and compartmentalized flow channel modules, it enables automated transfer of cut flowers from the main line to the compartments. The inclined sections utilize gravity-assisted sliding, while the horizontal sections provide stable storage, reducing manual intervention. It features rubber strips and nylon cloth; applying lubricant to the nylon cloth surface during use protects the flower stems from mechanical damage, reduces the coefficient of friction, and prevents scratches on the cut flower surface.

[0049] Furthermore, the compartmentalized pushing assembly includes a compartmentalized cylinder, a compartmentalized pushing plate mounted on the cylinder's push rod, and a rubber block covering the portion of the pushing plate that contacts the flower stem. The compartmentalized cylinder provides a stable pushing force, while the rubber block buffers the contact pressure, preventing damage to the flower stem during pushing.

[0050] Furthermore, the compartmentalized feeding assembly also includes a feeding mounting base plate installed on the main line for sorting fresh-cut flowers. A compartmentalized cylinder is located on the lower surface of the feeding mounting base plate, and a shock-absorbing pad is installed at the end of the cylinder furthest from the push rod. The feeding mounting base plate is equipped with an adjusting bolt for adjusting the position of the compartmentalized cylinder, with one end of the adjusting bolt abutting against the shock-absorbing pad. The lower surface of the feeding mounting base plate is equipped with a guide support wheel supporting the compartmentalized cylinder, located outside the cylinder and slidably connected to it. The shock-absorbing pad reduces the vibration noise of the compartmentalized cylinder; the adjusting bolt flexibly adjusts the cylinder position to adapt to different flower patterns; and the guide support wheel enhances the stability of the cylinder's movement and extends its service life.

[0051] Furthermore, the rubber block includes an integrally formed U-shaped portion and an O-shaped portion. The U-shaped portion is fitted and installed at the contact edge between the compartment pusher plate and the flower stem. The U-shaped portion is firmly fixed to the edge of the pusher plate, while the O-shaped portion acts as a buffer for the flower stem, providing double protection to avoid rigid contact.

[0052] Furthermore, a buffer pad is provided between the lower surface of the pusher mounting base plate and the compartment cylinder. The buffer pad further reduces vibration transmission between the cylinder and the base plate, reducing noise and structural wear.

[0053] Furthermore, the outer side of the compartmentalized cylinder is provided with a groove, and the guide support wheel is slidably connected to the groove. The slidable connection between the groove and the guide wheel can precisely limit the movement trajectory of the cylinder, prevent deviation, and ensure the consistency of the pushing direction.

[0054] Furthermore, the main cut flower sorting line is equipped with a flow channel display that shows the detection information of the cut flowers. The flow channel display is set up one-to-one with the sorting flow channel. The flow channel display shows the cut flower sorting information (such as variety and grade) in real time, which is convenient for operators to monitor and verify the accuracy of sorting.

[0055] Furthermore, the compartmentalized flow channel module includes a vibration motor, which is located at the high end of the inclined section. The vibration motor can assist the cut flowers to slide smoothly down the inclined section, preventing them from piling up and getting stuck, and is especially suitable for varieties with stems that are prone to tangling.

[0056] Furthermore, the compartment flow channel module includes a full-load detection sensor, which is located at the high end of the inclined segment. The full-load detection sensor can automatically monitor the compartment capacity, trigger an alarm or stop the material supply, and avoid blockage or damage caused by overload.

[0057] Furthermore, the compartment rack is a modular rack that is easy to assemble and disassemble. The modular rack facilitates transportation, assembly, and subsequent maintenance, adapts to different compartment quantity requirements, and has strong scalability.

[0058] The beneficial effects of this utility model are: This utility model is reasonably designed and has the following advantages:

[0059] (1) Simple structure, compact mechanism, low cost; the front and rear arc segments of the annular flower assembly and the main line carrier can be pushed and handed over, not only at the tangent point, and the time for pushing and handing over is more generous.

[0060] (2) In the flower handover mechanism, the flower stems of the fresh cut flowers are manually placed into the flower opening of the flower handover carrier on the slow straight section. The drive wheel assembly and the driven wheel assembly drive the flower handover carrier on the ring flower handover assembly to circulate and transport the fresh cut flowers along the direction of the flower handover synchronous belt. By utilizing the difference between the straight section distance and the arc length at the end of the arc section, the linear speed becomes high speed in the arc turning section. The pusher assembly pushes the fresh cut flowers from the flower opening of the flower handover carrier into the flower opening of the high speed conveyor main line carrier. By utilizing the principle of slow conveying in the straight section and high speed conveying in the arc section, the action of slow manual feeding of fresh cut flowers and handover to the high speed conveyor line is completed.

[0061] (3) In the flower transfer mechanism, the ring flower transfer component and the pusher component work together to achieve seamless transfer of fresh cut flowers from the auxiliary line to the main line. The conveying speed of fresh cut flowers in the arc section is consistent with the conveying speed on the main line, which significantly improves the conveying efficiency and is suitable for large-scale production.

[0062] (4) In the flower handover mechanism, the low-speed section of fresh cut flowers is manually fed and the high-speed section is handed over and conveyed, making manual operation more convenient.

[0063] (5) The leaf-removing mechanism is equipped with a stem-clamping component for clamping the flower stems of fresh cut flowers, a leaf-removing component for performing online leaf-removing action in the direction of movement of fresh cut flowers, and a horizontal waste discharge flow line for collecting waste branches and leaves, which improves the degree of production automation, saves manual operation, and significantly improves production efficiency.

[0064] (6) The leaf-removing mechanism has a good leaf-removing function and can accurately remove leaves by setting different leaf-removing ratios according to different length specifications of fresh cut flowers. Attached Figure Description

The drive shaft 1-23 passes through the drive wheel flange 1-25 and is connected to the flower-shaped drive motor 1-21. The drive wheel flange 1-25 is installed on the drive mounting slot 1-14.

[0112] The timing belt support plate 1-16 is located below the straight and arc sections of the upper timing belt 1-41.

[0113] Driven wheel assembly 1-3 includes a driven synchronous wheel 1-31 and a driven rotating shaft 1-32, with the driven rotating shaft 1-32 passing through the driven synchronous wheel 1-31; a driven wheel flange 1-33 is provided above the driven synchronous wheel 1-31, and the driven wheel flange 1-33 is sleeved on the outside of the driven rotating shaft 1-32, and the driven wheel flange 1-33 is installed on the driven mounting groove 1-15; the driven wheel assembly 1-3 also includes a driven tensioning block 1-34 for adjusting the position of the driven wheel assembly 1-3, and the driven tensioning block 1-34 is installed on the side wall of the driven wheel flange 1-33.

[0114] The annular upper flower assembly 1-4 also includes multiple upper flower fixing blocks 1-43 and multiple carrier connecting plates 1-44.

The upper flower fixing blocks 1-43 connected to the upper flower carrier 1-42 and the upper flower fixing blocks 1-43 connected to the rear end of the carrier connecting plate 1-44 are distributed adjacently.

[0115] The material pushing assembly 1-5 includes a material pushing cylinder 1-51, a material pushing plate 1-52 is installed on the push rod of the material pushing cylinder 1-51, and the material pushing cylinder 1-51 is installed on the material pushing frame 1-1 through the material pushing mounting plate 1-53.

[0116] Both the main carrier 2-7 and the flower-upper carrier 1-42 have flower-upper openings.

[0117] The handover process of the flower-attaching mechanism 1 is as follows:

[0118] During operation, the flower-upper drive motor 1-21 drives the connected drive shaft 1-23 to rotate, which in turn drives the drive synchronous pulley 1-22 mounted in the middle of the drive shaft 1-23 and the flower stem lever 1-24 on the lower side to rotate. The drive wheel flange 1-25 of the drive wheel assembly 1-2 is installed in the drive mounting slot 1-14 hole of the flower-upper frame 1. The driven wheel flange 1-33 of the driven wheel assembly 1-3 is installed in the driven mounting slot 1-15 hole of the flower-upper frame 1. The driven shaft 1-32 passes through the driven wheel flange 1-33 and is connected to the driven synchronous pulley 1-3 on the lower side. 1. The driven shaft 1-32 and the driven synchronous pulley 1-31 rotate synchronously. The upper pattern synchronous belt 1-41 of the annular upper pattern assembly 1-4 covers the outer ring of the driving pulley assembly 1-2 and the driven pulley assembly 1-3. The synchronous belt support plate 1-16 contacts the lower edge of the upper pattern synchronous belt 1-41 to provide support. The driven tension block 1-34 of the driven pulley assembly 1-3 pushes the driven synchronous pulley 1-31 to tension the upper pattern synchronous belt 1-41. The driving synchronous pulley 1-22 drives the upper pattern synchronous belt 1-41 to rotate along the annular direction, thereby driving the upper pattern carrier 1-42 to rotate in annular motion.

[0119] On the straight sections on both sides of the flower-raising synchronous belt 1-41, the cut flowers are placed into the flower-raising openings on the front side of the flower-raising carrier 1-42. The cut flowers move along the circular direction of the flower-raising synchronous belt 1-41 with the flower-raising carrier 1-42, that is, the cut flowers are transported from the straight section to the arc turning section. In the arc turning section, the flower stem lever 1-24 on the lower side of the drive wheel assembly 1-2 drives the lower flower stem of the cut flowers to move synchronously with the flower-raising openings of the flower-raising carrier 1-42 in the forward circumferential direction, which can effectively control the posture of the cut flowers during the transport in the arc section.

[0120] When in a straight section, the distance between the flower openings on the front sides of two adjacent flower-feeding carriers 1-42 is L1, and the conveying speed of the cut flowers is V1; the center distance on the rear sides of two adjacent flower-feeding carriers 1-42 is L3, and the conveying speed of the flower-feeding synchronous belt 1-41 is V3; when the cut flowers are conveyed in a straight section, L1=L3, V1=V3;

[0121] When the flowers are in the arc turning section, the distance between the flower openings on the front side of two adjacent flower-feeding carriers 1-42 is L2, and the conveying speed of the cut flowers is V2; the center distance on the rear side of two adjacent flower-feeding carriers 1-42 is L3, and the conveying speed of the flower-feeding synchronous belt 1-41 is V3. When the cut flowers are conveyed in the arc turning section, L2 > L3, V2 > V3. Therefore, it can be seen that the conveying speed of the cut flowers in the arc turning section is V2 > the conveying speed of the cut flowers in the straight section is V1. The main carrier 2-7 of the main line of cut flowers also conveys forward at a speed of V2.

[0122] The pusher assembly 1-5 is installed at the tangential position between the annular flower-feeding assembly 1-4 and the main carrier 2-7 in the direction of movement, and is located below the flower-feeding carrier 1-42. When the flower-feeding carrier 1-42 transports the cut flowers to the area before and after the tangential position, the flower-feeding pusher cylinder 1-51 is activated, driving the flower-feeding pusher plate 1-52 to move forward, pushing the cut flowers from the flower-feeding opening of the flower-feeding carrier 1-42 into the flower-feeding opening of the main carrier 2-7. The flower-feeding pusher cylinder 1-51 continues to push forward until the main carrier 2-7 drives the cut flowers forward and transports them past the tangential point. Then, the flower-feeding pusher cylinder 1-51 drives the flower-feeding pusher plate 1-52 to retract, waiting for the next cut flower to be transported. This achieves the effect of manual feeding of cut flowers at low speed and handover transportation at high speed.

[0142] The specific working process of leaf-beating mechanism 4 is as follows:

[0143] When the main carrier 2-7 reaches the leaf-beating area, the flower stem enters between the two sets of stem-clamping unit components. The flower stem is clamped and fixed by the foam synchronous belt and driven forward by the stem-clamping drive wheel 4-23, the stem-clamping driven wheel 4-24, and the stem-clamping motor 4-25. The upper flower opening of the main carrier 2-7 is supported by the wear-resistant support strip 4-210 to prevent the carrier from jamming due to force during leaf beating. The motion motor 4-34 on the leaf-beating motion component 4-3 drives it to reciprocate with the three sets of gripper unit components. When the gripper unit components reach the preset leaf-beating position, the leaf-beating telescopic cylinder 4-42 drives the first gripper 4-44 and the second gripper 4-45 to move towards the flower stem position. After the leaf-beating telescopic cylinder 4-42 is activated, the first... The gripper cylinders 4-46 and 4-47 then drive the first gripper 4-44 and the second gripper 4-45 to close and clamp the flower stem, holding the lower branches and leaves of the cut flower. The linear motion module 4-31 of the leaf-beating motion assembly 4-3 is installed at an angle inside the leaf-beating frame 4-1. The motion motor 4-34 controls the linear motion module 4-31 to move the leaf-beating gripper assembly 4-4 at an angle downward. The movement of the linear motion module 4-31 can be divided into a horizontal forward speed and a vertical downward speed. The horizontal forward speed is the same as the belt speed of the stem clamping unit assembly. The flower stem of the cut flower is tightly clamped by the stem clamping unit assembly. The leaf-beating gripper assembly 4-4 vertically downward clamps and pulls down the lower branches and leaves of the cut flower, knocking the leaves off.

[0144] The blades on the first gripper 4-44 and the second gripper 4-45 can effectively remove excess branches, leaves, and thorns. After leaf removal, the first gripper cylinder 4-46 and the second gripper cylinder 4-47 drive the first gripper 4-44 and the second gripper 4-45 to release the flower stem. After the grippers are released, the leaf removal telescopic cylinder 4-42 then drives the first gripper 4-44 and the second gripper 4-45 to retract and move away from the flower stem. Subsequently, the leaf removal motion assembly 4-3 returns to its origin, completing one leaf removal cycle. Leaf removal gripper assembly 4-4 It includes three sets of gripper unit components, which move synchronously with the main carrier 2-7 according to a set program, improving leaf removal efficiency while ensuring the best leaf removal effect. After leaf removal, the cut flowers continue to be conveyed forward by the main carrier 2-7. When they reach the outlet, they are guided out by the guide guard plate 4-27 and then enter the next process flow. Waste branches and leaves generated during the leaf removal process are conveyed into the waste box or waste bin for centralized treatment through the horizontal waste discharge line 4-5 and the lifting waste discharge line 4-6.

[0157] The compartment rack 5-21 is a modular rack that is easy to assemble and disassemble. During transportation, it significantly reduces the space occupied by the compartment rack 5-21, thus lowering transportation costs.

[0158] The working process of the compartmenting mechanism 5 is as follows: The user pre-configures the flow channel attributes. After the cut flowers are graded and tested, their grade is confirmed. The main carrier 2-7 clamps the cut flowers and moves with the main carrier conveyor 2 to the corresponding compartment flow channel 5-22. The compartmenting pusher component 5-1 works, and the compartmenting cylinder 5-11 drives the compartmenting pusher plate 5-12 to push out, kicking the cut flowers from the main carrier 2-7 into the corresponding compartment flow channel 5-22. The cut flowers flow along the inclined section 5-221 into the horizontal section 5-222. During this process, the vibration motor 5-23 is used to increase the smoothness of the flow of the cut flowers. Then, the automatic compartmenting action continues. When the full material detection sensor 5-24 detects a signal, it triggers a prompt. A person comes to pick up the flowers and sorts and classifies them or transports them to the subsequent workstation according to the prompts on the flow channel display 5-4.
