Description

Technical Field

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

[0002] Fruit bagging, without affecting or damaging the normal growth and ripening of fruit, not only isolates the fruit from pesticides and environmental pollution, making it pollution-free, but also protects it from pests, diseases, and dust, resulting in a smoother surface, brighter color, and improved quality. Simply put, fruit bagging is like a coat for the fruit, playing a very important role.

[0003] Currently, most fruit bagging is still done manually, which has several problems, such as low efficiency, high cost, and inability to guarantee consistent bagging quality. Fruit bagging devices are available on the market, but they generally suffer from issues such as being heavy and difficult to hold, large and inconvenient to operate, and lacking smooth operation.

[0004] To address these issues, we aim to develop a semi-automatic fruit bagging device to replace traditional manual bagging methods or existing inconvenient bagging devices. This will have a positive impact on the development of the fruit industry, providing a more reliable solution for fruit production. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems in the prior art and provide a fruit bagging device. This device is small and lightweight, and the bagging work is more efficient and convenient. Fruit farmers can greatly improve production efficiency, reduce labor costs, and ensure the quality and consistency of fruit bagging.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fruit bagging device includes a box body, wherein a baffle is provided inside the box body to divide the box body into front and rear parts;

[0008] The rear part of the box contains a compression spring and a pressure cover arranged from back to front. The two ends of the compression spring are connected to the rear side of the box and the pressure cover, respectively. A sleeve is provided between the pressure cover and the baffle.

[0009] The front part of the box contains, from front to back, a paper separating and opening mechanism and a sealing mechanism;

[0010] The paper separating and opening mechanism includes a roller assembly and a paper separating and opening motor. The paper separating and opening motor is used to drive the adhesive roller in the roller assembly to rotate. The baffle is provided with a first notch for the adhesive roller to contact the bag, and the lower end of the baffle is provided with a second notch for bag output.

[0011] The sealing mechanism includes a sealing gripper, a sealing motor, a sealing base plate, and a movable pressure rod. The sealing gripper includes a linkage mechanism, a gripper fixing part, a gripper plane part, and a spring. The sealing motor is connected to the gripper fixing part through the linkage mechanism. The gripper fixing part is hinged to the gripper plane part. The two ends of the spring are respectively connected to the gripper plane part and the linkage mechanism. The sealing base plate is located below the sealing gripper, and the movable pressure rod is horizontally located between the sealing gripper and the sealing base plate.

[0012] The roller assembly includes an upper roller, a lower roller, an upper gear, a lower gear, an upper connecting rod, and a lower connecting rod; the upper roller, the paper separating and opening motor, and the upper gear are rotatably connected to the upper connecting rod in sequence, and the upper roller and the lower roller are adhesive; the lower roller and the lower gear are rotatably connected to the lower connecting rod in sequence, and the lower gear meshes with the upper gear, and a gap is provided between the lower roller and the upper roller for inserting a bag.

[0013] The size of the first notch is larger than that of the upper roller so that the upper roller can fully contact the bag.

[0014] The upper and lower gears are identical to ensure that the upper and lower rollers rotate synchronously.

[0015] The sealing gripper is provided in two parts, and the two parts are connected by a gripper connecting rod; the gripper fixing part is designed in an arch shape; the gripper plane part extends in the opposite direction at the hinge.

[0016] This utility model also includes a support rod and a tension spring. The support rod is located on one side of the box body. The movable pressure rod is rotatably connected to the support rod. The two ends of the tension spring are respectively connected to the movable pressure rod and the support rod.

[0017] This utility model also includes a telescopic mechanism, which is connected to the rear side of the box to accommodate fruit trees of different heights.

[0018] The telescopic mechanism includes a handle, a telescopic rod, a telescopic rod drive motor, and a push-button switch; the handle is located at the rear end of the telescopic rod, and the front end of the telescopic rod is connected to the housing; the telescopic rod drive motor is connected to the telescopic rod and is used to drive the telescopic rod to extend and retract; the push-button switch is embedded on the surface of the handle, and the push-button switch includes a first push-button switch for controlling the telescopic rod drive motor, a second push-button switch for controlling the paper separating and opening motor, and a third push-button switch for controlling the sealing motor.

[0019] This utility model also includes a photoelectric switch and a proximity switch. The photoelectric switch is located at the sealing position of the bag and is used to detect the bag position and control the stopping of the paper separating and opening motors. There are two proximity switches. One proximity switch is located at the position where the gripper fixing part contacts the bottom plate. The other proximity switch is located on the housing, flush with the highest position that the sealing gripper can be raised, and is used to control the forward and reverse rotation of the sealing motor.

[0020] A bendable metal wire or strip is attached to each of the two sides of the middle of the bag.

[0021] In use, place an appropriate amount of fruit bags with the open end facing the bottom plate into the box. Press the second button switch, and the corresponding motor will drive the upper gear to rotate. The upper gear drives the upper roller to roll through the upper connecting rod. The sticky upper roller, when rolling, uses friction and adhesion to bring the first bag from the vertical position to the gap between the upper and lower rollers. At this time, the gear transmission makes the upper and lower rollers roll simultaneously. The adhesion of the two rollers makes the bag continue to be transported and open. When the bag covers the sensor of the photoelectric switch, the switch is turned off, the paper separating and opening motor stops working, the upper and lower rollers stop rolling, and the paper separating and opening steps are completed. Align the open bag with the young fruit, allowing the fruit to enter the bag. Press the third button switch controlling the sealing motor. The sealing motor operates, driving the connecting rod to rotate, which in turn causes the sealing gripper to press down. As the sealing gripper continues to press down, the reverse extension of the gripper's flat surface comes into contact with the movable pressure rod, causing the spring to extend and open the sealing gripper. At this point, the forward part of the gripper's flat surface presses against the front sealing position of the bag. The front of the bag bends downward under the combined action of the sealing base plate below and the downward pressure of the forward part of the gripper's flat surface. As the gripper continues to press down, the reverse part of the gripper's flat surface disengages from the movable pressure rod. The gripper's flat surface and the gripper's fixed part quickly close under the stretching action of the spring, clamping the bent front of the bag between the two parts, thus folding the front edge of the bag in half and completing the sealing action. At this point, the gripper has moved down to its lowest position. Under the sensing of the proximity switch below, the sealing motor reverses, and the gripper begins to move upward. When it rises to a certain height, the movable pressure rod is held in place by the sealing gripper. Because there is a tension spring at the connection between the movable pressure rod and the support rod, the spring extends after being held upward, thus the movable pressure rod is pushed upward by the sealing gripper. As the sealing gripper continues to rise, it disengages from the movable pressure rod, and the movable pressure rod is then pulled back to the horizontal position by the spring. When the gripper reaches the position of the proximity switch above, the sealing motor stops rotating and prepares for the next action.

[0022] Compared with the prior art, the beneficial effects achieved by the technical solution of this utility model are:

[0023] 1. This utility model is designed for bagging with wire. It utilizes a motor structure to complete a series of actions such as bagging, conveying, opening and sealing, thereby achieving high-efficiency bagging of young fruit.

[0024] 2. This utility model cleverly utilizes inexpensive and readily available compression springs to replace complex devices such as pressure sensors, ensuring the bag is firmly pressed onto the rollers and preventing displacement during transport. Furthermore, this design offers excellent flexibility, allowing the spring's elasticity to be adjusted according to the bag's size or thickness.

[0025] 3. This utility model cleverly utilizes two adhesive rollers to achieve a series of actions such as bag transfer and opening.

Detailed Implementation

[0042] To make the technical problems, solutions, and beneficial effects of this invention clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. Those skilled in the art should understand other possible implementations and the advantages of this invention, such as the ingenious use of rollers with built-in adhesive for transporting paper bags, which eliminates the need for traditional complex transport machinery and achieves automation and intelligence in paper bag transport. The components in the figures are not drawn to scale and are only used for illustrative purposes.

[0043] See Figures 1-4 The fruit bagging device described in this embodiment includes a box body 6, and a baffle 20 is provided inside the box body 6 to divide the box body 6 into front and rear parts;

[0044] The rear part of the box 6 is provided with a compression spring 11 and a pressure cover 12 from back to front. The two ends of the compression spring 11 are respectively connected to the rear side of the box 6 and the pressure cover 12. A bag is provided between the pressure cover 12 and the baffle 20.

[0045] The rear part of the box 6 stores several bags. The size of the storage space for the bags can be designed according to actual needs, without too many restrictions. The bags can be pressed tightly between the cover 12 and the baffle 20. When the paper is reduced, the paper will be squeezed by the cover 12 and slide towards the baffle 20, so that the paper will not tilt to the side.

[0046] The pressure cap 12 is connected to the compression spring 11, which is always in a compressed state. When the amount of paper decreases, the force on the paper storage side of the pressure cap 12 decreases, and the compression spring 11 tends to return to its original length on the paper storage side. This can drive the pressure cap 12 to push the remaining paper, so that the remaining paper is clamped again by the pressure cap 12 and the baffle 20. The elasticity of the compression spring 11 can be adjusted according to different bag sizes and thicknesses, and no further restrictions are imposed here.

[0047] The state of the bag before it is removed is as follows Figure 5 As shown, the bag installation method is as follows: the open end of the bag faces the bottom, the flat surface of the bag is parallel to the baffle 20 and the pressure cover 12, and the flat surface of the bag with the wire faces the baffle 20. Several bags are stacked in sequence. When the first bag is pulled out, the second bag will remain in place and will not be pulled out because the friction between the second bag and the first bag is less than the friction between the first bag and the upper roller. This process can be repeated to complete the bag removal action.

[0048] The front part of the box is provided with a paper separating and opening mechanism and a sealing mechanism from front to back.

[0049] The paper separating and opening mechanism includes an upper roller 19, a lower roller 17, an upper gear 14, a lower gear 15, an upper connecting rod 18, and a lower connecting rod 16. The upper roller 19, the paper separating and opening motor 21, and the upper gear 14 are rotatably connected to the upper connecting rod 18 in sequence. The upper roller 19 has an adhesive component. The lower roller 17 and the lower gear 15 are rotatably connected to the lower connecting rod 16 in sequence, and the lower gear 15 meshes with the upper gear 14. A slit is provided between the lower roller 17 and the upper roller 19 for inserting a bag. The upper gear 14 and the lower gear 15 are identical to ensure synchronous rotation of the upper and lower rollers.

[0050] The baffle 20 is provided with a first notch 30 for the upper roller 19 to contact the bag, and the lower end of the baffle 20 is provided with a second notch 31 for bag output;

[0051] Specifically, one side of the upper roller 19 is adhesive, and the adhesive part initially contacts the bag. As the upper roller 19 rolls, friction and adhesiveness carry the bag from a vertical position to the horizontal gap between the upper and lower rollers for the bag to be inserted. By cleverly utilizing the position of the upper roller 19, the paper separating device and the opening device are cleverly integrated, greatly improving the paper separating efficiency and simplifying the mechanical structure.

[0052] The lower roller 17 is sticky throughout its circumference. Due to the one-to-one transmission between the upper gear 14 and the lower gear 15, the upper and lower rollers rotate and stop simultaneously at the same speed. When the bag enters the gap between the upper roller 19 and the lower roller 17, the bag is opened by the friction between the upper roller 19 and the lower roller 17 and the stickiness of the two rollers. Figure 6As shown, when the bag is rolled by the rollers to the horizontal position with the photoelectric switch, the photoelectric switch is blocked. At this time, the switch is turned off, the paper separating and opening motors stop working, the upper and lower rollers stop rolling, and the opening is completed.

[0053] The sealing mechanism includes a sealing gripper, a sealing motor 22, a sealing base plate 10, and a movable pressure rod 8; there are two sealing grippers, and the two are connected by a gripper connecting rod 29.

[0054] Each sealing gripper includes a linkage mechanism, a gripper fixing part 26, a gripper flat part 27, and a spring 28;

[0055] The linkage mechanism includes link 23, link 24 and link 25, wherein one end of link 23 is rotatably connected to link 25 through a bearing, the middle part of link 23 is rotatably connected to link 24 through a bearing, the other end of link 23 is fixedly connected to the gripper fixing part 26, and the other ends of link 24 and link 25 are rotatably connected to the box body through a connecting plate.

[0056] The sealing motor is connected to the connecting rod 25 of one of the sealing grippers. The gripper fixing part 26 is hinged to the gripper plane part 27, and the gripper fixing part 26 has an arched design. The gripper plane part 27 extends in the opposite direction at the hinge. The two ends of the spring 28 are respectively connected to the gripper plane part 27 and the connecting rod 23. The sealing base plate 10 is located below the sealing gripper. The movable pressure rod 8 is horizontally located between the sealing gripper and the sealing base plate 10, and is rotatably connected to the support rod through a tension spring. The support rod is located on one side of the box. Figures 7-8 As shown, when the reverse extension of the gripping plane 27 contacts the movable pressure rod 8 and continues to press down, the spring 28 continues to extend, causing the sealing gripping to open; as Figures 8-9 As shown, as the gripper continues to press down, the reverse part of the gripper plane 27 moves downward and disengages from the movable pressure rod 8. Under the action of the spring 28, the gripper plane 27 quickly closes with the gripper fixing part 26, that is, the sealing gripper closes.

[0057] When the third button switch 3 controlling the sealing motor 22 is turned on, the sealing motor rotates, driving the connecting rod 25 to rotate. The other two connecting rods 23 and 24 in the linkage mechanism are driven accordingly because they are connected to each other through bearings, thereby driving the sealing gripper to press down. The sealing gripper stops pressing down after hitting the sealing base plate 10. At the same time as hitting the sealing base plate 10, the front edge of the sealing gripper will bend the front wire of the bag to achieve sealing. At this time, the sealing gripper has moved down to the lowest position. Under the sensing of the proximity switch below, the sealing motor reverses, and the sealing gripper begins to move upward. When the sealing gripper reaches the position of the proximity switch above, the motor stops rotating, the sealing gripper stops moving, and enters the preparation for the next action.

[0058] In this embodiment, the telescopic mechanism can use a common structural design available on the market, and no further restrictions are imposed here. The first button switch 1 controls the operation of the telescopic rod drive motor to achieve the purpose of extending and shortening the telescopic rod; the second button switch 2 controls the operation of the paper separating and opening motor 21. After pressing the second button switch 2, the upper connecting rod 18 is driven to rotate, causing the upper roller 19 to rotate; at the same time, the upper gear 14 is driven by the upper connecting rod 18, and the lower gear 15 is driven by the upper gear 14, thereby driving the lower connecting rod 16 to rotate, causing the lower roller 17 to rotate; the third button switch 3 controls the sealing motor 22 to rotate, thereby driving the linkage mechanism to transmit power and causing the sealing gripper to press down.

[0059] The photoelectric switch 9 is located at the sealing position of the bag and is used to detect the bag position and control the stopping of the paper separating and opening motor 21.

[0060] Two proximity switches are provided. One proximity switch is located at the position where the gripper fixing part 26 contacts the sealing base plate 10. The other proximity switch is located on the housing 6, flush with the highest position that the sealing gripper can be raised, and is used to control the forward and reverse rotation of the sealing motor 22.

[0061] As an optimization of the above embodiments, such as Figure 4 As shown, the sealing gripper is designed with an arched shape to take into account that the flat sealing gripper would press down on the young fruit, thus improving the accuracy of sealing and bagging; the sealing gripper is designed to ensure that the middle of the sealing gripper will not touch the young fruit, so two identical sealing grippers are designed and connected by gripper connecting rod 29.

[0062] As an optimization of the above embodiments, such as Figure 14 As shown, a novel bagging design is presented. The notch remains in the middle of the bag, and two metal wires or strips are located at each of the four equal divisions of the bag's width near the opening. In this embodiment, iron wires are used. When the sealing clamp presses down, the iron wires are squeezed and bent, thus achieving the sealing purpose. Simultaneously, when the young fruit is placed in the bag, it should be visually positioned at the middle notch, with the fruit branches extending from the notch, further reducing interference from the sealing clamp on the young fruit.

[0063] To better understand this utility model, the working principle of this utility model will be described in detail below:

[0064] During operation, the fruit bagging device of this utility model is operated through a telescopic mechanism, facilitating flexible operation among fruit trees of different heights. When bagging is required, first press the first button switch 1 controlling the telescopic rod drive motor, adjust the housing 6 to the appropriate position, and then press the second button switch 2 controlling the paper separating and opening motor. This causes the motor to drive the upper and lower gears to rotate, thereby driving the upper and lower rollers to rotate. The bag is brought to a horizontal position by the adhesion and friction of the upper roller 19. At this point, the bag opens due to the adhesion and friction of the upper and lower rollers until the bag reaches the detection point of the photoelectric switch 9. At this point, the paper separating and opening motor 21 stops rotating, completing the paper separating and opening. Next, the operator holds the device and aligns the notch in the middle of the opened bag with the young fruit, allowing the young fruit to enter the bag. Then, press the third button switch 3 controlling the sealing motor 22, causing the sealing motor 22 to rotate, driving the linkage mechanism to rotate, thereby pressing down the sealing gripper. Figures 9-10 As shown, when the sealing gripper continues to press down, the spring 28 continues to extend due to the contact and force between the reverse extension portion of the gripper plane 27 and the movable pressure rod 8, causing the sealing gripper to open. At this time, the forward portion of the gripper plane 27 abuts against the front sealing position of the bag. Under the combined action of the sealing base plate 10 supported below the bag and the downward pressing process of the forward portion of the gripper plane 27, the front end of the bag bends downward. As the gripper continues to press down, the reverse portion of the gripper plane 27 moves downward and disengages from the movable pressure rod 8. Under the action of the spring 28, the gripper plane 27 quickly closes with the gripper fixing portion, clamping the bent front end of the bag between the two parts of the gripper, thereby folding the front edge of the bag in half and completing the sealing action. At this time, the gripper has moved down to the lowest position. Under the sensing of the proximity switch below, if... Figures 11-13 As shown, the motor reverses, and the gripper begins to move upward. When it is raised to a certain height, the movable pressure rod 8 is held in place by the sealing gripper. Since there is a tension spring 7 at the connection between the movable pressure rod 8 and the support rod 13, the spring 7 extends after being held upward, so the movable pressure rod 8 is pushed upward by the sealing gripper. As the sealing gripper continues to rise, the sealing gripper will disengage from the movable pressure rod 8, and the movable pressure rod 8 will be pulled back to the horizontal position by the spring 7. When the gripper reaches the proximity switch position above, the motor stops rotating and prepares for the next action.

[0065] This invention ingeniously utilizes rollers with built-in adhesive for bag transfer, eliminating the need for traditional complex mechanical transfer devices and achieving automated and intelligent bag transfer. The entire process requires no other complex mechanical components, greatly simplifying the system structure and reducing maintenance costs. This design also fully considers the efficiency and accuracy of bag transfer, using photoelectric switches to precisely control the bag's position, ensuring the bag accurately reaches the target location.

[0066] This invention cleverly utilizes the elasticity of a compression spring to firmly press the bag against the rollers. The compression spring uses its own rebound force to securely press the bag against the rollers, preventing displacement during transport. This design also offers good adaptability; simply adjusting the spring's tension allows it to accommodate different bag sizes and thicknesses, making the entire system more flexible and versatile. Furthermore, since complex pressure sensors are not required, system maintenance and calibration become simple and convenient. When the compression spring ages, only a new one needs to be replaced, significantly reducing costs and meeting market demands.

[0067] This invention cleverly utilizes springs, hinges, and other structures to improve the sealing gripper structure, and cleverly uses unidirectional support to quickly open the sealing gripper under force, thus achieving the sealing action simply and accurately.

[0068] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
