Description

Technical Field

[0001] This invention belongs to the field of agricultural planting machinery, specifically a bagging and packaging mechanism for grapes on trellises. Background Technology

[0002] Grape bagging is a crucial step in grape cultivation. It protects grapes from pests and improves fruit color, sugar content, and quality. It also reduces pesticide use, playing a vital role in food safety and environmental protection. Currently, bagging trellis grapes is primarily done manually, requiring the grapes to be wrapped in a bag, the bag opening to be sealed, and finally, the grape stems to be tied to the bag opening with tape. This manual method is time-consuming and labor-intensive.

[0003] In addition, when grapes are ready for sale after harvesting, they also need to be packaged manually, which is time-consuming, labor-intensive and inefficient.

[0004] In summary, how to achieve automated bagging and packaging of grapes has become an urgent problem for researchers in this field. Summary of the Invention

[0005] The technical problem to be solved by this invention is: how to achieve automated bagging and packaging of grapes;

[0006] This invention relates to a bagging and packaging mechanism for trellis grapes, comprising: a frame having an upper support plate and a lower support plate; an upper opening located at the upper support plate for grapes to pass through; a lower opening located at the lower support plate below the upper opening; a bag-opening assembly disposed between the upper and lower support plates; a bag-sealing assembly disposed at the lower opening for sealing the bag; and a binding assembly disposed between the bag-opening assembly and the bag-sealing assembly. When the bag-opening assembly absorbs and opens the bag, placing the bag opening between the upper and lower openings, grapes fall into the bag through the upper opening. The bag-sealing assembly seals the bag opening along with the grape stem. The binding assembly binds the sealed bag opening along with the grape stem using tape, and then cuts the tape after binding.

[0007] In this solution, the top opening and bottom opening are arranged in a straight line, with a bag opening assembly, a binding assembly, and a mouth-binding assembly arranged sequentially. The bag opening assembly is used to open the bag opening until it is bound. The mouth-binding assembly binds the bag opening along with the grape stem. The binding assembly binds the bag opening. In this way, the bag can be placed on the grape, realizing automated bagging and packaging of grapes.

[0008] Similarly, when packaging grapes for sale, operators only need to lift the stem to package the grapes, thus achieving automated bagging and packaging of grapes.

[0009] To illustrate the specific structure of the bag-opening assembly, the present invention employs a bag-opening assembly comprising: a first suction cup, which is fixed to the upper support plate by a first suction cup frame and located on one side above the lower opening; a support plate, which is slidably disposed at the bottom of the upper support plate by a first power component; a flipping frame, which is rotated and disposed at the bottom of the support plate by a rotating motor; and a second suction cup, which is fixed to the flipping frame and located on the other side above the lower opening. When the second suction cup is reversed to a downward position by the rotating motor, it adsorbs the packaging bag. After adsorption is completed, the second suction cup is rotated to be positioned opposite the first suction cup, and the second suction cup is brought close to the first suction cup by the first power component, adsorbing the other side of the packaging bag. The first power component is then reset, opening the bag opening.

[0010] The second suction cup can both suck up the bag downwards under the drive of the rotating motor and move linearly along the length of the frame under the drive of the first power component. When the second suction cup rotates to a horizontal position and approaches the first suction cup, it will simultaneously adhere to the packaging bag. After the second and first suction cups move away from each other, the opening of the packaging bag can be opened to facilitate the entry of grapes.

[0011] To illustrate the specific structure of the first power assembly, the present invention uses a first power assembly comprising: an electric push rod, the cylinder of which is fixed to the bottom of the upper support plate, and the output end of which is connected to the support plate; and a slider, which is disposed on the top of the support plate and slidably connected to a slide rail on the frame.

[0012] When the electric actuator is activated, its output end extends, causing the support plate to slide, which in turn drives the second suction cup to move in a straight line.

[0013] To illustrate the specific structure of the sealing assembly, the present invention employs a sealing assembly comprising: an annular base plate disposed on the lower support plate and located at the lower opening; an annular cover plate covering the annular base plate; multiple rotors equally spaced on the annular base plate; multiple stacked arc-shaped blades, each rotor having a fixed arc-shaped blade; a synchronous pulley controlled by a motor and disposed on the annular base plate; and a synchronous belt meshing with each rotor and the synchronous pulley. When the motor starts, the synchronous belt rotates under the drive of the synchronous pulley, driving each rotor to rotate, causing the multiple arc-shaped blades to rotate synchronously and extend out of the window opened in the inner ring of the annular cover plate. The inner arcs of the multiple arc-shaped blades act on the packaging bag, sealing the packaging bag.

[0014] The drawstring assembly is similar to the aperture component of an optical camera. It rotates multiple arc-shaped blades simultaneously and uses the inner arc to drawstring the bag opening. During the contraction process, it pushes the crooked grape stems to the center, making it easier for the subsequent binding mechanism to bind them.

[0015] The base plate is also provided with two tensioning rollers; the two tensioning rollers are rotatably located on both sides of the synchronous roller and are wound around the synchronous belt;

[0016] The main synchronous belt pulley is driven by a motor, which in turn drives the rotor to rotate. However, considering that the span of the synchronous belt is very large and the length of the synchronous belt is difficult to control, two tensioning pulleys are set between the main synchronous belt pulley and the rotor. This allows the effective length of the synchronous belt to be adjusted.

[0017] To illustrate the specific structure of the arc-shaped blade and the rotor, the present invention uses an arc-shaped blade with a thickness of 1 / 2 of the rotor thickness; the arc-shaped blade is arranged obliquely upward from the connection point with the rotor.

[0018] To ensure the blades remain stacked during operation, the upper surface of the rotor is beveled, and the rotor thickness is 5mm. This allows the curved blades to be stacked during installation, reducing the overall thickness of the device and minimizing deformation caused by the compression between the curved blades during rotation. The blades are designed to be narrower at the top and wider at the bottom, with a thickness of 2.5mm. This design also ensures that the curved blades remain stacked during operation. However, deformation is inevitable during rotation, so the curved blades are made of acrylic resin, which has high toughness and a relatively smooth surface.

[0019] To illustrate the specific structure of the binding assembly, the present invention uses a binding assembly comprising: a translation component for driving the first box and the second box to move synchronously along the width direction of the frame; a gap is formed between the first box and the second box for the bag opening to pass through after the drawstring closure; a rotating post disposed within the second box; an adhesive tape sleeved on the rotating post, its end positioned at the ratchet via a guide post, and rotatably disposed within the second box; a pawl rotatably disposed within the first box, its end abutting against the groove of the ratchet; and a first spring. The system connects the pawl and the first housing; a cutter holder, rotatably mounted inside the second housing and connected to the second housing via a second spring, with a cutter mounted thereon; and a profile holder, rotatably mounted inside the first housing and connected to the first housing via a third spring, with its end supporting the extension of the cutter holder. When the bag opening after the drawstring passes through the gap, the pawl rotates under force to embed the tape into the groove, and the tape adheres to the pawl, wraps around the bag opening once, and then passes the cutter holder, which rotates under force to rotate the cutter and cut the tape.

[0020] The ratchet and pawl are shaped to match, with the pawl meshing as perfectly as possible in the ratchet's groove to ensure sufficient tape adhesion. The profile holder and the front end of the cutter holder need to be tightly clamped together, so the profile holder must be longer than the cutter holder, with the front end resting on the support section of the cutter holder. The cutter holder's dimensions must ensure that it can smoothly cut the tape after being forced to rotate a certain angle. During installation, the tape is mounted on the rotating column of the second housing. The tape is wound around the ratchet via the guide column, and the pawl embeds the tape into the ratchet's groove and adheres it to the surface for tape removal. (First housing, second housing) There are gaps between the parts, and the entrance is rounded to facilitate the bag opening entering the channel. When binding, the bound bag opening passes through the gap, pushing the pawl downward and pulling out the tape to wrap around the bag opening. After the tape is wrapped, the pawl will re-engage with the ratchet with the excess tape. Then the bag opening continues to move forward, pushing the cutter on the cutter holder to cut the tape. At the same time, the profile holder and the cutter holder pinch the cut tape. After binding is completed, each part returns to its initial position by springs, and the pawl re-embeds the tape into the groove of the ratchet and sticks the tape to the surface, completing the cycle.

[0021] To illustrate the specific structure of the translation component, the present invention employs a translation component comprising: a main drive shaft disposed along the length of the frame; a first drive shaft rotatably disposed on one side of the lower opening along the width of the frame, and connected to the main drive shaft via a bevel gear pair; a second drive shaft rotatably disposed on the other side of the lower opening along the width of the frame, and connected to the main drive shaft via a bevel gear pair; a drive motor connected to the main drive shaft via a bevel gear pair; a first connecting rod connected to the first housing, and connected to the first drive shaft via a lead screw pair; and a second connecting rod connected to the second housing, and connected to the second drive shaft via a lead screw pair. When the drive motor is started, it drives the main drive shaft to rotate, and the main drive shaft drives the first drive shaft and the second drive shaft to rotate via the bevel gear pair; the first drive shaft and the second drive shaft drive the first connecting rod and the second connecting rod to move along the width of the frame via corresponding lead screw pairs, thereby driving the first housing and the second housing to move along the width of the frame.

[0022] In this way, by driving the rotation of the motor, the first box and the second box can move synchronously along the width direction of the frame.

[0023] The beneficial effects of this invention are as follows: This invention is a bagging and packaging mechanism for trellis grapes. The mechanism comprises a bag-opening component, a binding component, and a mouth-binding component arranged sequentially in a straight line with an upper and lower opening. The bag-opening component opens the bag until it is bound. The mouth-binding component then binds the bag opening along with the grape stem. Finally, the binding component binds the bag opening. This allows the bag to be placed over the grapes, achieving automated bagging and packaging. Similarly, when packaging grapes for sale, operators only need to hold the stem to complete the packaging, thus achieving automated bagging and packaging of grapes. Attached Figure Description

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0036] like Figure 1-9As shown, the present invention is a bagging and packaging mechanism for trellis grapes, comprising: a frame 10 having an upper support plate 11 and a lower support plate 12; an upper opening 13 disposed at the upper support plate 11 for grapes to pass through; a lower opening 14 disposed at the lower support plate 12, located below the upper opening 13; and a bag-opening assembly 2 disposed between the upper support plate 11 and the lower support plate 12. A drawstring assembly 3 is disposed at the lower opening 14 and is used to draw the opening of the packaging bag; a binding assembly 4 is disposed between the drawstring assembly 3 and the bag opening assembly 2; when the bag opening assembly 2 absorbs the packaging bag and opens, the opening of the packaging bag is placed between the upper opening 13 and the lower opening 14, and the grapes fall into the packaging bag through the upper opening 13; the drawstring assembly 3 works to draw the opening of the packaging bag together with the grape stem; the binding assembly 4 works to bind the opening of the packaged bag together with the grape stem with tape, and the binding assembly 4 cuts the tape after binding.

[0037] In this solution, the top opening and bottom opening are arranged in a straight line, with a bag opening assembly, a binding assembly, and a mouth-binding assembly arranged sequentially. The bag opening assembly is used to open the bag opening until it is bound. The mouth-binding assembly binds the bag opening along with the grape stem. The binding assembly binds the bag opening. In this way, the bag can be placed on the grape, realizing automated bagging and packaging of grapes.

[0038] Similarly, when packaging grapes for sale, operators only need to lift the stem to package the grapes, thus achieving automated bagging and packaging of grapes.

[0039] like Figure 3-4 As shown, to illustrate the specific structure of the bag-opening assembly, the present invention uses a bag-opening assembly 2 comprising: a first suction cup 21, which is fixed to the upper support plate 11 by a first suction cup frame 22 and located on one side above the lower opening 14; a support plate 23, which is slidably disposed at the bottom of the upper support plate 11 by a first power component; a flipping frame 24, which is rotated and disposed at the bottom of the support plate 23 by a rotating motor 25; and a second suction cup 26, which is fixed to the flipping frame 24 and located on the other side above the lower opening 14. When the second suction cup 26 is reversed to a downward position by the rotating motor 25, it adsorbs the packaging bag. After adsorption is completed, the second suction cup 26 is rotated to be positioned opposite to the first suction cup 21, and the second suction cup 26 is brought close to the first suction cup 21 by the first power component, adsorbing the other side of the packaging bag. The first power component is then reset, opening the bag opening.

[0040] The second suction cup can both suck up the bag downwards under the drive of the rotating motor and move linearly along the length of the frame under the drive of the first power component. When the second suction cup rotates to a horizontal position and approaches the first suction cup, it will simultaneously adhere to the packaging bag. After the second and first suction cups move away from each other, the opening of the packaging bag can be opened to facilitate the entry of grapes.

[0041] like Figure 3-4 As shown, in order to illustrate the specific structure of the first power assembly, the present invention adopts a first power assembly including: an electric push rod 27, the cylinder of which is fixed to the bottom of the upper support plate 11, and the output end of which is connected to the support plate 23; and a slider, which is disposed on the top of the support plate 23 and is slidably connected to the slide rail on the frame 10.

[0042] When the electric actuator is activated, its output end extends, causing the support plate to slide, which in turn drives the second suction cup to move in a straight line.

[0043] like Figure 5 As shown, to illustrate the specific structure of the sealing assembly, the present invention uses a sealing assembly 3 comprising: an annular base plate 31, which is disposed on the lower support plate 12 and located at the lower opening 14; an annular cover plate 32, which covers the annular base plate 31; a plurality of rotors 33, which are equally spaced on the annular base plate 31; a plurality of stacked arc-shaped blades 34, with each rotor 33 having a fixed arc-shaped blade 34; a synchronous pulley 35, which is controlled to rotate by a motor 36 and disposed on the annular base plate; and a synchronous belt (not shown in the figure), which meshes with each rotor 33 and the synchronous pulley. When the motor 36 starts, the synchronous belt rotates under the drive of the synchronous pulley 35, and drives each rotor 33 to rotate, causing the plurality of arc-shaped blades 34 to rotate synchronously and extend out of the window opened in the inner ring of the annular cover plate 32. The inner arc of the plurality of arc-shaped blades 34 acts on the packaging bag and seals the packaging bag.

[0044] The drawstring assembly is similar to the aperture component of an optical camera. It rotates multiple arc-shaped blades simultaneously and uses the inner arc to drawstring the bag opening. During the contraction process, it pushes the crooked grape stems to the center, making it easier for the subsequent binding mechanism to bind them.

[0045] like Figure 5 As shown, the base plate 31 is also provided with two tensioning rollers 37; the two tensioning rollers 37 are rotatably located on both sides of the synchronous pulley 35 and are wound around the synchronous belt;

[0046] The main synchronous belt pulley is driven by a motor, which in turn drives the rotor to rotate. However, considering that the span of the synchronous belt is very large and the length of the synchronous belt is difficult to control, two tensioning pulleys are set between the main synchronous belt pulley and the rotor. This allows the effective length of the synchronous belt to be adjusted.

[0047] like Figure 6-7 As shown, in order to illustrate the specific structure of the arc-shaped blade and the rotor, the present invention adopts the arc-shaped blade 34 with a thickness of 1 / 2 of the rotor 33; the arc-shaped blade 34 is obliquely upward from the connection point with the rotor 33.

[0048] like Figure 6-7 As shown, in order to ensure that the blades remain stacked during operation, the upper surface of the rotor is inclined and the rotor thickness is 5mm. This allows the curved blades to be stacked on top of each other during installation, reducing the overall thickness of the device and reducing the deformation caused by the compression between the curved blades during rotation. As for the blades, they are designed with a shape that is narrower at the top and wider at the bottom, with a thickness of 2.5mm. This is also to ensure that the curved blades remain stacked during operation. However, the blades inevitably deform during rotation, so the material for the curved blades is acrylic resin with high toughness and a relatively smooth surface.

[0049] like Figure 8-9 As shown, to illustrate the specific structure of the strapping assembly, the present invention uses the strapping assembly 4, which includes: a translation component, used to drive the first box 41 and the second box 42 to move synchronously along the width direction of the frame 10; a gap 43 is formed between the first box 41 and the second box 42 for the bag opening to pass through after the drawstring is closed; a rotating post 44, which is disposed inside the second box 42; an adhesive tape, which is sleeved on the rotating post 44, and whose end is placed at the ratchet 46 via a guide post 45; a ratchet 46, which is rotatably disposed inside the second box 42; a pawl 47, which is rotatably disposed inside the first box 41, and whose end abuts against the groove of the ratchet 46; and a first spring 48, which is connected to the... The device comprises a pawl 47, a first housing 41, a cutter holder 49 rotatably disposed within a second housing 42 and connected to the second housing 42 via a second spring 410, and a cutter 411 disposed thereon; and a profile holder 412 rotatably disposed within the first housing 41 and connected to the first housing 41 via a third spring 413, the end of which is used to support the extension section 414 of the cutter holder 49. When the bag opening after the drawstring passes through the gap 43, the pawl 47 is subjected to force and rotates to embed the adhesive tape into the groove. After the tape adheres to the pawl 47 and wraps around the bag opening once, when it passes the cutter holder 49, the cutter holder 49 is subjected to force and rotates to rotate the cutter 411 and cut the tape.

[0050] like Figure 10As shown, the ratchet and pawl are shaped to match, with the pawl meshing as perfectly as possible in the ratchet's groove to ensure sufficient tape adhesion. The profile holder and the front end of the cutter holder need to be tightly clamped together, so the profile holder must be longer than the cutter holder, with the front end resting on the support section of the cutter holder. The cutter holder's dimensions must ensure that it can smoothly cut the tape after being forced to rotate a certain angle. During installation, the tape is mounted on the rotating column of the second housing, and the tape is wound around the ratchet via the guide column. The pawl embeds the tape into the ratchet's groove and adheres it to the surface for tape removal. The first housing and the second... There are gaps between the boxes, and the entrance is rounded to facilitate the bag opening entering the channel. When binding, the bound bag opening passes through the gap, pushing the pawl downward and pulling out the tape to wrap around the bag opening. After the tape is wrapped, the pawl will re-engage with the ratchet with the excess tape. Then the bag opening continues to move forward, pushing the cutter on the cutter holder to cut the tape. At the same time, the profile holder and the cutter holder pinch the cut tape. After binding is completed, each part returns to its initial position by springs, and the pawl re-embeds the tape into the groove of the ratchet and sticks the tape to the surface, completing the cycle.

[0051] like Figure 9 As shown, to illustrate the specific structure of the translation component, the present invention employs a translation component comprising: a main drive shaft 51 disposed along the length direction of the frame; a first drive shaft 52, rotatably disposed on one side of the lower opening 14 along the width direction of the frame, and connected to the main drive shaft 51 via a bevel gear pair; a second drive shaft 53, rotatably disposed on the other side of the lower opening 14 along the width direction of the frame, and connected to the main drive shaft 51 via a bevel gear pair; a drive motor 54, connected to the main drive shaft 51 via a bevel gear pair; and a first connecting rod 55, connected to the first housing 41, which... The first drive shaft 52 is connected via a lead screw pair; the second connecting rod 56 is connected to the second housing 42 and is connected to the second drive shaft 53 via a lead screw pair; when the drive motor 54 starts, it drives the main drive shaft 51 to rotate, and the main drive shaft 51 drives the first drive shaft 52 and the second drive shaft 53 to rotate via a bevel gear pair; the first drive shaft 52 and the second drive shaft 53 drive the first connecting rod 55 and the second connecting rod 56 to move along the width direction of the frame 10 via corresponding lead screw pairs, thereby driving the first housing 41 and the second housing 42 to move along the width direction of the frame 10;

[0052] In this way, by driving the rotation of the motor, the first box and the second box can move synchronously along the width direction of the frame.

[0053] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
