Description

Technical Field

[0001] This invention belongs to the field of bagging equipment, specifically relating to a handheld automatic apple bagging machine. Background Technology

[0002] To prevent pests and diseases and reduce pesticide residues, young apples are usually bagged. Plastic apple bags are important for apples due to their advantages in cost, waterproofing, and light transmission. Traditional bagging is done manually, requiring the apple bag to be manually opened, placed on the apple, and then the bottom of the bag to be tied. This manual bagging method is time-consuming, labor-intensive, has low automation, and is difficult to improve efficiency. In large-scale orchards, bagging requires a large amount of manpower and results in high labor costs. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides a handheld automatic apple bagging machine that is simple to operate, highly efficient, and can improve the automation level of bagging, effectively reducing labor intensity and labor costs.

[0004] The specific technical solution adopted in this invention is as follows:

[0005] A handheld automatic apple bagging machine includes a housing, a control handle mounted on the housing, and a bag unfolding mechanism, a bag supporting mechanism, a cutting mechanism, a bag top sealing mechanism, and a bag bottom sealing mechanism arranged sequentially on the housing along the conveying direction of the apple bags. The housing also includes a closing mechanism that matches the bag bottom sealing mechanism. The bag bottom sealing mechanism includes a sealing strip roller, a first conveying roller group, a winding roller group, and a cutting knife arranged sequentially along the conveying direction of the sealing strip. The winding roller group includes a first shaping roller and a second shaping roller. The first shaping roller is provided with an inner guide groove and an outer guide groove. The second shaping roller is matched with the outer guide groove. The sealing strip passes through the outer guide groove and the inner guide groove in sequence and then spirally winds around the closed apple bag to seal it.

[0006] The closing mechanism includes a box body with a closing yarn roller, a second conveying roller group and a clamping roller group arranged sequentially on the box body along the conveying direction of the closing yarn. The box body is provided with a through hole for the apple bag to pass through. A guide groove for the closing yarn is opened on the side wall of the through hole. The clamping roller group is located at the entrance end of the guide groove. The closing yarn roller is fixedly connected to the end of the guide groove.

[0007] The elastic cover plates are arranged in pairs on both sides of the guide groove, and the two elastic cover plates in the pair are spaced apart.

[0008] The bag top sealing mechanism includes an electric gripper and a first heating wire. The electric gripper includes a pair of claw bodies arranged in a V-shape. The first heating wire is disposed on the working surface of the claw body, and the apple bag passes between the working surfaces of the claw body.

[0009] The bag-supporting mechanism includes an outer ring and a bag-supporting block. The outer ring has a conical cavity with a larger diameter at the top and a smaller diameter at the bottom. The bag-supporting block is located inside the conical cavity and is matched with the outer ring. A bag-supporting conveying channel is formed between the bag-supporting block and the outer ring. A set of drive rollers is provided on the side wall of the conical cavity.

[0010] The outer ring and the bag support block are equipped with magnetic suction components. The bag support block is connected to the outer ring by means of the magnetic suction components, and the magnetic suction components are located above the drive roller.

[0011] A rubber layer is provided on the side wall of the conical cavity and the side wall of the bag support block, and the rubber layer covers the surface of the magnetic suction component.

[0012] The housing is provided with a first telescopic rod and a second telescopic rod. The first telescopic rod is connected to the outer ring, and the second telescopic rod is matched with the upper end of the bag support block. The cutting mechanism includes a ring-shaped second heating wire, which is located at the bottom of the conical cavity and is fixedly connected to the side wall of the conical cavity.

[0013] The bag unfolding mechanism includes an apple bag roller and an unfolding pair of rollers, wherein the apple bag is folded in the width direction.

[0014] The beneficial effects of this invention are:

[0015] This invention integrates a bag unfolding mechanism, a bag supporting mechanism, a cutting mechanism, a bag top sealing mechanism, a bag bottom sealing mechanism, and a closing mechanism on the machine casing. Apple bags are unfolded and conveyed in the form of a roll. After being opened by the bag supporting mechanism, the apple bags pass through the cutting mechanism, the bag top sealing mechanism, the bag bottom sealing mechanism, and the closing mechanism in sequence under the action of gravity, realizing the cutting, sealing, closing, and sealing operations respectively. There is no need to manually twist open and seal the apple bag opening, which effectively reduces the workload and improves the work efficiency.

[0016] When sealing the bottom, the closing mechanism first closes the bottom of the apple bag. The sealing strip is spirally structured after being output by the winding roller group and gradually coils around the closing part of the apple bag. Then, the cutting knife cuts the sealing strip coiled on the apple bag from the sealing strip output by the first conveying roller group. The friction between the apple bag and the sealing strip makes the sealing strip lock with the apple bag and prevent the sealing strip from falling off. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] Specific implementation examples Figure 1As shown, this invention relates to a handheld automatic apple bagging machine, comprising a housing 1, a control handle 2 mounted on the housing 1, and a bag unfolding mechanism 4, a bag supporting mechanism 5, a cutting mechanism 6, a bag top sealing mechanism 7, and a bag bottom sealing mechanism 8 sequentially mounted on the housing 1 along the conveying direction of the apple bags 3. The housing 1 also includes a closing mechanism 9 that matches the bag bottom sealing mechanism 8. The housing 1 is composed of multiple interlocking shells.

[0030] The control handle 2 has a drive button, and the housing 1 is equipped with a power supply, controller, and drive motor. The controller is programmed with the working program of the bagging machine. When the operator holds the control handle 2 and presses the drive button, the controller drives the bag roller 4, bag support mechanism 5, cutting mechanism 6, bag top sealing mechanism 7, bag bottom sealing mechanism 8, and closing mechanism 9 to move in coordination according to the working program to achieve automatic bagging. In this embodiment, the closing mechanism 9 is located below the bag bottom sealing mechanism 8.

[0031] During operation, hold the control handle 2 so that the discharge end of the bag-opening mechanism 5 faces downwards, meaning the opened apple bag 3 output by the bag-opening mechanism 5 faces downwards. Press the drive button, and the controller controls the bag-unfolding mechanism 4 to transport the apple bag. After the folded apple bag 3 is opened by the bag-opening mechanism 5, it passes under gravity through the cutting mechanism 6, the top sealing mechanism 7, the bottom sealing mechanism 8, and the closing mechanism 9. The apple bag 3 is placed on the apple from top to bottom. The top sealing mechanism 7 seals the part of the apple bag 3 located between the cutting mechanism 6 and the top of the apple. The closing mechanism 9 gathers the apple bag at the stem end. The bottom sealing mechanism 8 seals the apple bag 3 near the closing point. The cutting mechanism 6 cuts the apple bag 3 above the top sealing mechanism 7. Using this bagging machine for apple bagging eliminates the need for manual twisting and sealing of the apple bag 3 opening, effectively reducing labor intensity and improving work efficiency.

[0032] The bag unfolding mechanism 4 includes an apple bag roller 23 and an unfolding pair of rollers 24. The apple bag 3 is folded in the width direction, as shown below. Figure 10 As shown, when the apple bag 3 is on the apple bag roller 23, its edges are folded in a wavy pattern to reduce the width of the apple bag 3, thereby reducing the width of the apple bag roller 23 and the bag unfolding roller 24. The bag unfolding roller 24 is rotated under the control of the controller, unfolding the apple bag 3 from the apple bag roller 23 and conveying it to the bag-supporting mechanism 5.

[0033] The bag-supporting mechanism 5 includes an outer ring 27 and a bag-supporting block 28, such as Figure 1-2As shown, the outer ring 27 is connected to the housing 1. The outer ring 27 has a conical cavity with a larger diameter at the top and a smaller diameter at the bottom. The bag-supporting block 28 is located inside the conical cavity and is matched with the outer ring 27. A bag-supporting conveying channel is formed between the bag-supporting block 28 and the outer ring 27. A set of drive rollers 29 are provided on the side wall of the conical cavity. The bag-supporting block 28 is a conical ring mechanism with a larger diameter at the top and a smaller diameter at the bottom and a hole in the middle. The bag-supporting block 28 is inserted between the conical cavities of the outer ring 27. The outer ring 27 supports the bag-supporting block 28 to prevent it from falling downward. The bag-supporting block 28 is located inside the apple bag 3 and opens the apple bag 3. The drive roller 29 is connected to the drive motor through a flexible shaft. The drive roller 29 presses the apple bag 3 against the side wall of the bag-supporting block 28. The forward rotation of the drive roller 29 makes the apple bag 3 smoothly conveyed downward in the bag-supporting conveying channel.

[0034] Furthermore, a magnetic suction component 30 is provided on the outer ring 27 and the bag support block 28. The magnetic suction component 30 is located above the drive roller 29. The bag support block 28 is connected to the outer ring 27 by means of the magnetic suction component 30. In this embodiment, magnets are embedded on the outer ring 27 and the bag support block 28 respectively. The magnets on the outer ring 27 and the bag support block 28 attract each other and form the magnetic suction component 30. The magnets are arranged at multiple intervals along the bag support conveying channel. The mutual attraction between the magnets fixes the bag support block 28 and the outer ring 27 relatively, preventing the bag support block 28 from falling off the outer ring 27 when flipping or moving.

[0035] Rubber layers 22 are respectively provided on the side wall of the conical cavity and the side wall of the bag support block 28. The rubber layers 22 cover the surface of the magnetic suction assembly 30. The rubber layers 22 increase the distance between the magnets in the magnetic suction assembly 30, reduce the suction force, and at the same time reduce the friction between the outer ring 27 and the bag support block 28 on the apple bag 3, so as to prevent the apple bag 3 from being torn.

[0036] When the output length of the apple bag 3 reaches one step, the cutting mechanism 6 cuts the portion of the apple bag 3 that is fitted onto the apple from the initially opened apple bag 3. The housing 1 is equipped with a first telescopic rod 31 and a second telescopic rod 32. The first telescopic rod 31 is connected to the outer ring 27, and the second telescopic rod 32 is fitted to the upper end of the bag-supporting block 28. The cutting mechanism 6 includes a ring-shaped second heating wire located at the bottom of the conical cavity and fixed to the side wall of the conical cavity. The first telescopic rod 31 retracts, causing the outer ring 27 to rise, while the second telescopic rod 32 extends, restricting the position of the bag-supporting block 28, causing the outer ring 27 to slightly move upward relative to the bag-supporting block 28. The second heating wire presses the apple bag 3 tightly onto the bag-supporting block 28 and heats it, causing the apple bag 3 to melt and break. Subsequently, the first telescopic rod 31 drives the outer ring 27 and the bag-supporting block 28 to reset.

[0037] While the cutting mechanism 6 is working, the bag top sealing mechanism 7 seals the apple bag 3 from above. Figure 9As shown, the bag top sealing mechanism 7 includes an electric gripper 25 and a first heating wire 26. The electric gripper 25 includes a pair of V-shaped gripper bodies 2501. The first heating wire 26 is disposed on the working surface of the gripper bodies 2501, and the apple bag 3 passes between the working surfaces of the gripper bodies 2501. The controller controls the gripper bodies 2501 of the electric gripper 25 to close together, clamping and flattening the apple bag 3. At the same time, the first heating wire 26 heats up, adhering the side walls of the apple bag 3 to form a closed top of the apple bag 3. Because the electric gripper 25 closes the apple bag 3, it creates a pulling action on the apple bag 3, which also prevents the apple bag 3, after being heat-melted and cut, from sticking to the second heating wire.

[0038] Meanwhile, the finishing mechanism 9 is in operation. For example... Figure 3 , Figure 4 As shown, the closing mechanism 9 includes a box 18 with a closing roller 17, a second conveying roller group 20 and a clamping roller group 21 arranged sequentially on the box 18 along the conveying direction of the closing wire 19. The box 18 has a through hole for the apple bag 3 to pass through. A guide groove 1801 for the closing wire 19 is opened on the side wall of the through hole. The clamping roller group 21 is located at the entrance end of the guide groove 1801. The closing roller 17 is fixedly connected to the end of the guide groove 1801. The closing mechanism 9 is located at the apple stem. When closing the apple bag 3, the second conveying roller group 20 reverses, pulling the closing wire 19 in the guide groove 1801 back to the closing roller 17, so that the closing wire 19 forms a ring structure with a cross-sectional area smaller than the cross-sectional area of ​​the through hole in the through hole, thereby closing the opened apple bag 3 and bringing the lower end of the apple bag 3 together into an hourglass-shaped structure. After the closing mechanism 9 completes the closing work, the electric gripper 25 opens.

[0039] like Figure 5 , Figure 6 , Figure 7 As shown, the bag bottom sealing mechanism 8 includes a sealing strip roller 11, a first conveying roller group 12, a winding roller group 13, and a cutting knife 14 arranged sequentially along the conveying direction of the sealing strip 10. The winding roller group 13 includes a first shaping roller 15 and a second shaping roller 16. The first shaping roller 15 is provided with an inner guide groove 1501 and an outer guide groove 1502. The second shaping roller 16 is matched with the outer guide groove 1502. After the sealing strip 10 passes through the outer guide groove 1502 and the inner guide groove 1501 in sequence, it spirals around the waist of the hourglass-shaped apple bag 3 to seal it. The first conveying roller group 12 rotates to unfold and convey the sealing strip 10 on the sealing strip roller 11. When the sealing strip 10 passes through the outer guide groove 1502 on the first shaping roller 15, the second shaping roller 16 squeezes the sealing strip 10, causing the sealing strip 10 to bend and gradually spiral near the closing position of the apple bag 3, as shown. Figure 8As shown, during the spiraling process, the end of the sealing strip 10 passes through the inner guide groove 1501, which further shapes the sealing strip 10. The spirally coiled sealing strip 10 binds the lower end of the apple bag 3, preventing the lower end of the apple bag 3 from opening. Then, the cutting blade 14 moves to cut the sealing strip 10. The spirally coiled sealing strip 10 is fixed to the apple bag 3 under the friction force and will not fall off.

[0040] The cutting blade 14 is moved by means of an electric telescopic rod.

[0041] The drive roller 29 on the outer ring 27 reverses, causing the apple bag 3 in the bag-supporting conveying channel to move upward, preventing the apple bag 3 from sticking to the second heating wire. Subsequently, the drive roller 29 and the bag-spreading roller 24 work together to convey the apple bag 3 outward by one step length.

[0042] In this embodiment, the closing wire 19 is a steel bar. In the closing mechanism 9, the second conveying roller group 20 rotates forward and conveys the closing wire 19 to the guide groove 1801. The clamping roller group 21 guides the closing wire 19, and the closing wire 19 is pressed back into the guide groove 1801 in preparation for closing the apple bag 3.
