Description

Technical Field

[0001] This application relates to the field of agricultural machinery technology, and in particular to a fruit and vegetable bagging device. Background Technology

[0002] Fruit and vegetable bagging is a technology developed to improve appearance quality, reduce pesticide residues, and mitigate damage from daily pests, diseases, wind, rain, and sunlight.

[0003] Currently available fruit bagging machines involve operators extending the machine towards the fruit to bag it. However, some problems have been discovered during use. Since most bagging machines open the bag using suction cups or adhesive, the suction cup method relies heavily on the negative pressure and the adhesion to the bag. If the negative pressure is too low or the adhesion is poor, the bag may not be able to be sucked up. Using adhesive to open the bag is another option, but since the adhesive layer cannot be replaced during the bagging process, prolonged use may cause its adhesive properties to deteriorate, making it unable to adhere to the bag and requiring interruption of the bagging process for replacement, which is time-consuming. Therefore, these methods may result in bags leaking out when removing them. Utility Model Content

[0004] The technical problem to be solved by this application is to provide a fruit and vegetable bagging device that prevents bag leakage during the bag removal process, so as to ensure the smooth progress of the bagging work.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0006] A fruit and vegetable bagging device, comprising:

[0007] The base has a storage bag cavity at the top and a heating and bonding component at the front end of the storage bag cavity. The heating and bonding component includes a heating part and a first adhesive rotating cylinder. The top surface of the heating part has a first through hole for the adhesive rotating cylinder to pass through.

[0008] The control console component, located above the base, includes a first motor and a swing platform. The shaft of the first motor is connected to the side wall of the swing platform. A groove is provided on the top of the swing platform, and a telescopic component is provided in the groove. A second motor is provided on the top surface of the swing platform, and a rotating component for controlling the movement of the telescopic component is provided on the shaft of the second motor.

[0009] The opening and closing component is located above the base and at the front end of the control console assembly. It includes a first connecting arm and a second connecting arm. The first connecting arm is connected to the front end of the telescopic component. A through hole is provided on the left side of the front end of the swing platform. The rear end of the second connecting arm is movably disposed in the through hole. An opening and closing plate is connected to the front end of the first connecting arm and the second connecting arm. A second adhesive rotating cylinder is provided on the opening and closing plate. A through hole is provided on the opening and closing plate for the adhesive rotating cylinder to pass through.

[0010] The telescopic component of the control console moves the opening and closing component upwards towards the bag storage cavity of the base. Then, the control console presses down, causing the second adhesive roller of the opening and closing plate to adhere the top of the bag. After the control console is raised, the telescopic component moves the opening and closing component forward, bringing the bottom of the bag into contact with the first adhesive roller of the heated adhesive component. When the opening and closing component reopens, the bag opening opens randomly, allowing for bagging. This invention reliably bags fruits and vegetables.

[0011] Further extending the above scheme, baffles are provided on the left and right sides of the storage cavity to prevent the bag from falling out.

[0012] To avoid damaging the stems of fruits and vegetables, in some embodiments, the heated adhesive component has a clearance opening in the middle.

[0013] In some embodiments, the heating element includes a heat insulation pad and a heating wire, with the heating wire disposed on the heat insulation pad.

[0014] In order to achieve the extension and retraction of the telescopic component, in some embodiments, the telescopic component is a rack and pinion.

[0015] According to the extended embodiment of this utility model, the rotating component is a gear.

[0016] Compared with existing technologies, this application achieves at least the following beneficial effects: This fruit and vegetable bagging device uses a combination of a second adhesive rotating cylinder and a first adhesive rotating cylinder to realize a series of operations such as taking out the bag, opening the bag mouth, and closing the bag mouth. First, this device only requires a small amount of adhesive force to take out the plastic bag. Second, this device simplifies the steps of taking out the bag and sealing the bag. By controlling the back-and-forth movement of the opening and closing part and adjusting the opening and closing angle of the opening and closing part through the control console component, the bag taking out and opening the bag can be realized. Finally, the plastic bag mouth is heated by the heating part to shrink and seal it, thus completing the bagging work. The first adhesive rotating cylinder and the second adhesive rotating cylinder can adjust their own rotation angle to ensure that the adhesive effect is not weakened. Therefore, during the bag taking process, there will be no leakage or bag jamming, ensuring that the bagging work is carried out smoothly. Attached Figure Description

[0025] The present application will now be described in detail with reference to exemplary embodiments shown in the accompanying drawings. However, it should be understood that the present application may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

Therefore, they should not be construed as limiting the scope of protection of this application.

[0027] To address the shortcomings of existing technologies in successfully bagging fruit, the inventors, after careful analysis, discovered that the main reasons for these problems are: Current bagging materials typically use plastic or paper bags. Suction cups are not well-suited for plastic bags because the bags easily deform after being attached, potentially making them impossible to open. For paper-based plastic bags, strong suction and a perfect fit between the paper and the suction cup are crucial for adhesion. If the suction is weak or there are gaps between the suction cup and the paper bag, it may fail to adhere. Regarding the adhesive layer, current methods often involve double-sided tape or glue applied to a flat surface. Over time, the adhesive weakens, making it impossible to stick the bag, requiring interruption of the bagging process and manual replacement of the adhesive layer, which is time-consuming. Based on these analyses, the inventors have made structural improvements to the fruit bagging machine.

[0028] like Figure 1-4 As shown, in one embodiment of a fruit and vegetable bagging device of this application, the device includes a base 1, which is composed of a bottom plate 11 and a side plate 13. The bottom plate 11 has an upwardly extending side plate 13 at its rear end. The top of the bottom plate 11 has a bag storage cavity 12 and a boss at its front end. The bottom of the boss has a cavity 111. The bag storage cavity 12 is used to place plastic bags. The depth of the cavity 12 is designed according to the situation. The boss restricts the forward movement of the bags in the bag storage cavity 12 through its rear end face. A heating and bonding component is provided on the boss at the front end of the bag storage cavity 12. The heating and bonding component includes a heating part and a first adhesive rotating cylinder 7. The first adhesive rotating cylinder 7 is located in the cavity 111. The top surface of the boss and the top surface of the heating part have a first through hole for the adhesive rotating cylinder to pass through.

[0029] The control console component 3, which is angle-adjustable, is located above the base 1 and includes a first motor 31 and a swing platform 32. The first motor 31 is fixedly mounted on the front end of the side plate 13, and a rotating shaft 16 is connected to its rotating shaft. On the right side of the first motor 31, a bushing 14 is fixedly connected to the front end of the side plate 13, and the rotating shaft 16 passes through the bushing 14. The swing platform 32 is a square plastic block with a certain thickness, and a right-angle opening is provided on its left rear side to avoid the bushing 14. The rotating shaft 16 on the rotating shaft of the first motor 31 and the left side wall of the right-angle opening of the swing platform 32 are fixed together. The first motor 31 can drive the swing platform 32 to swing at a certain angle. The top right side of the swing platform 32 has a groove, and a fixed slot block 36 is installed in the groove with an interference fit. The fixed slot block 36 is a long rectangular block with a fixed edge on the top left and a sliding groove on the top right. A telescopic component 33 is installed in the sliding groove. The top surface of the swing platform 32 is equipped with a second motor 35. Specifically, a fixed slot is provided on the fixed edge of the fixed slot block. The second motor 35 is fixed in the slot with screws. The shaft of the second motor 35 is equipped with a rotating component 34 that controls the movement of the telescopic component 33.

[0030] The opening and closing component 2, which is used to obtain the bag and open the bag opening, is located above the base 1 and at the front end of the control console assembly. It includes a first connecting arm 22 and a second connecting arm 23. The first connecting arm 22 is connected to the front end of the telescopic component 33 and extends obliquely downward to the top of the boss of the base 1. The second connecting arm 23 is symmetrically distributed on the left side of the first connecting arm 22. A through hole is opened on the left side of the front end of the swing platform 32. A crossbar 24 is connected to the rear end of the second connecting arm 23. A vertical bar 25 is connected to the right end of the crossbar 24 and is movably disposed in the through hole. The front end of the second connecting arm 23 extends obliquely downward to the top of the boss of the base 1. An opening and closing plate 21 matching the heating and bonding component is connected to the front end of the first connecting arm 22 and the second connecting arm 23. A second adhesive rotating cylinder 18 is provided on the opening and closing plate 21, and a through hole is opened on the opening and closing plate 21 for the adhesive rotating cylinder to pass through downward.

[0031] The bottom surface of the storage cavity 12 is inclined downward and backward. When the opening and closing component 2 picks up the bag, there may be static friction between the two bags at the top and bottom. If the bottom surface of the storage cavity 12 is set as a flat surface, when the opening and closing component 2 moves forward, the bottom bag may fall and the bag opening may fall onto the heating and bonding component. Since the storage cavity 12 is inclined, after the bottom bag falls, it will slide backward into the storage cavity 12, avoiding the bag opening of the unused bag from contacting the heating and bonding component, and ensuring that the opening and closing component 2 can cooperate with the heating and bonding component to open the bag opening after picking up the bag.

[0032] A trapezoidal baffle 10 is screwed and fixed to the left and right sides of the storage cavity 12 to prevent the bag from falling out from the sides during operation.

[0033] The heating element of the heating and bonding component consists of two parts, which are fixedly mounted on the left and right sides of the boss on the base 1, forming a clearance opening in the middle of the two heating elements. When the opening and closing plate 21 of the opening and closing component 2 presses against the top of the heating and bonding component, the fruit stalk or stem connected to the fruit and vegetable is located inside the clearance opening, preventing it from being pressed by the opening and closing plate 21.

[0034] The heating element includes a strip-shaped heat insulation pad 6 and a heating wire 8, with the heating wire 8 mounted on the heat insulation pad 6. The sealing and locking time of the bag by the heating wire 8 is adjusted by controlling a relay connected to the heating wire 8 to prevent overheating and heat melting of the bag opening.

[0035] The first adhesive drum 7 is a drum structure with an adhesive layer covering its outer wall. The adhesive layer can be double-sided tape or adhesive glue, and can be replaced when the adhesion is insufficient. The left and right ends of the first adhesive drum 7 are sealed. A first roller shaft 71 is provided at the axis of the left and right ends of the first adhesive drum 7. A driven gear 19 is provided on the first roller shaft 71. A transmission gear 20 that engages with the driven gear 19 is provided in the cavity 111 of the base 1. The transmission gear 20 is larger than the driven gear 19. A third motor 9 is provided on the right side wall of the base 1. The shaft of the third motor 9 is connected to the transmission gear 20.

[0036] like Figure 4 As shown, there are two heating parts, and correspondingly, there are two first adhesive rotating drums 7 connected by a first roller shaft 71. The driven gear 19 and the transmission gear 20 are both located on the right side of the cavity 111.

[0037] To prevent the first adhesive drum 7 from rotating when the third motor 9 is not working, an elastic limiting member 17 is provided on the right side wall of the cavity 111. Specifically, a through hole is opened on the right side wall of the cavity 111, and a movable pin 171 is provided in the through hole. A spring 172 is sleeved on the pin 171 located inside the cavity 111. A pressure block 173 with a diameter larger than that of the spring 172 is connected to the left end of the pin 171. A nut can be screwed onto the pin 171 outside the cavity 111. When the third motor 9 stops rotating, the spring 172 drives the pressure block 173 to press against the transmission gear 20 or the right end face of the first adhesive drum 7 through its elastic force, generating friction to constrain its rotation.

[0038] To achieve the extension and retraction of the telescopic component 33, the telescopic component 33 is preferably a rack and pinion, and the rotating component 34 is preferably a gear. When the gear rotates counterclockwise, the telescopic component 33 retracts, causing the opening and closing component 2 to move upward toward the storage cavity 12 of the base plate 11; when the gear rotates clockwise, the telescopic component 33 extends, causing the opening and closing component 2 to move upward toward the heating part.

[0039] This fruit and vegetable bagging device also includes a robotic arm 4 and a traveling unit 5. The side plate 13 of the base 1 is fixed to the front end of the robotic arm 4 by bolts. The traveling unit 5 is located below the robotic arm 4, and is supported by the traveling unit 5 to move the robotic arm 4 to the designated location of the fruit and vegetables. The robotic arm 4 is a six-degree-of-freedom vision robotic arm with a built-in camera; the traveling unit 5 is a tracked vehicle. Both the robotic arm 4 and the traveling unit 5 are equipped with encoders for remote control.

[0040] Combination Figure 4 and Figure 6As shown, the second adhesive drum 18 is a drum structure with an adhesive layer covering its outer wall. This adhesive layer can be double-sided tape or a sticky adhesive, and can be replaced when the adhesion is insufficient. The left and right ends of the second adhesive drum 18 are sealed. A second roller 181 is located at the axis of each end of the second adhesive drum 18. A rectangular receiving cavity 27 is provided at the top of the opening plate 21 to prevent the second adhesive drum 18 from being inserted. The left and right ends of the receiving cavity 27 have recesses for placing the second roller 181. The top of the receiving cavity 27 is open, and a top cover 26 is installed on the top. Two limiting rods 261, matching the recesses, are connected to the bottom of the top cover 26. The bottom surface of the limiting rods 261 is arc-shaped and conforms to the outer wall of the second roller 181. The top cover is fixed to the top of the receiving cavity 27 with screws. A fourth motor 15 is installed on the side of the receiving cavity 27, and the shaft of the fourth motor 15 is connected to the second roller 181. An elastic limiting member 17 is also provided on the side wall of the receiving cavity 27.

[0041] The function of the first adhesive drum 7 and the second adhesive drum 18 is that, when the exposed adhesive layer loses its adhesive force, the third motor 9 and the fourth motor 15 can drive the first adhesive drum 7 and the second adhesive drum 18 to rotate at a certain angle, so that the adhesive layer with adhesive force can continue to work, thus achieving continuous operation. For example, after 15-20 bagging operations, if it is found that the adhesive force of the adhesive layer of the first adhesive drum 7 has weakened, the third motor 9 can be used to adjust the first adhesive drum 7 to rotate by 5°, so that the adhesive layer with adhesive force is exposed in the heating part, thus ensuring that the bagging operation proceeds smoothly. The second adhesive drum 18 can do the same.

[0042] Work process:

[0043] The remote-controlled walking unit 5 moves to the position of the fruit and vegetables to be bagged, and the robotic arm 4 moves forward to move the base 1 in front of the fruit and vegetables to be bagged. The second motor 35 drives the rotating part 34 to rotate counterclockwise, causing the telescopic part 33 to drive the opening and closing part 2 to retract. The opening and closing plate 21 is located above the bag storage cavity 12, and the second motor 35 stops working. The first motor 31 rotates counterclockwise, and the swing platform 32 drives the opening and closing plate 21 of the opening and closing part 2 to swing towards the bag storage cavity 12. The opening and closing plate 21 sticks the bag at the top of the bag storage cavity 12 through the second adhesive rotating cylinder 18, and the shaft of the first motor 31 returns to the center. The second motor 35 rotates clockwise, causing the telescopic part 33 to drive the opening and closing part 2 to extend above the heat insulation pad 6 of the heating part. Then the first motor 31 rotates counterclockwise to press the opening and closing plate 21 against the top of the heating part. At this time, the lower half of the bag is bonded to the first adhesive rotating cylinder 7. The first motor 31 drives the opening and closing part 2 to swing clockwise, as... Figure 2As shown, the bag opening is opened; then the robotic arm 4 extends forward, covering the fruit and vegetables in front of it. The first motor 31 rotates counterclockwise, causing the opening and closing plate 21 to press against the heating part. The heating wire 8 of the heating part heats the bag opening, deforming and sealing it. Then, the first motor 31 rotates clockwise, opening the opening and closing part 2. Because the adhesive force of the first adhesive roller 7 on the heating part and the heating part on the bag is greater than the adhesive force of the second adhesive roller 18 on the opening and closing plate 21, the second adhesive roller 18 separates from the bag first. Finally, the robotic arm 4 moves backward, separating the first adhesive roller 7, the heating part, and the bag, completing the bagging process. Repeating the above actions allows for bagging the next fruit and vegetables.

[0044] If the adhesive layers of the first adhesive drum 7 and the second adhesive drum 18 lack adhesive force, the first adhesive drum 7 and the second adhesive drum 18 can be rotated at a certain angle by the third motor 9 and the fourth motor 15 to expose the adhesive layer with adhesive force, and then the operation can continue.

[0045] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this application should be within the protection scope of this application.
