Description

Technical Field

[0001] This utility model is a fruit bagging tool, belonging to the field of fruit bagging. Background Technology

[0002] In the fruit cultivation industry, bagging technology is a key cultivation measure to improve fruit quality and ensure production efficiency. Its core function is to effectively prevent pests and diseases, pesticide residues, and mechanical damage to the fruit from external environments such as wind, rain, and birds through physical isolation. At the same time, bagging can regulate the temperature, humidity, and light conditions inside the bag, promote uniform fruit coloring and smooth peel, and significantly enhance the commercial value and market competitiveness of the fruit. Currently, bagging technology has been widely used in the large-scale cultivation of mainstream economic fruits such as apples, pears, citrus, and grapes, becoming one of the core links in modern orchard management.

[0003] However, current orchard bagging operations are still mainly done manually. The process is cumbersome and labor-intensive, requiring multiple steps such as "taking the bag, opening the bag, putting the fruit on, and sealing it." It demands a high level of skill from the operators. During peak bagging periods (such as the young fruit stage of apples and the fruit expansion stage of citrus), the bagging efficiency is low, making it difficult to meet the timeliness requirements of large-scale orchards. Moreover, labor costs are rising year by year. To address the pain points of manual bagging, some simple bagging auxiliary tools have emerged in the industry. These tools use mechanical structures to help open the fruit bags, reducing the amount of labor involved in the bag-opening step. However, manual operations such as feeding the bag, sealing it, and cutting it are still required. The degree of automation is low, and the efficiency improvement is limited. Therefore, it is necessary to design a fruit bagging tool. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fruit bagging tool to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fruit bagging tool, comprising: The base features a truncated cone design that is thinner at the top and thicker at the bottom. The support rod is threaded to the top of the base; The handle is fixed to the bottom of one side of the support rod, and a control switch is provided on the handle; Mounting base, fixed to the top of the support rod; The roll bag assembly is located at the center of the top of the mounting base; There are two racks, which are symmetrically arranged on both sides of the top of the mounting base; The bag feeding mechanism is located between two frames above the roll bag assembly; The sealing mechanism is located between the two frames above the bag feeding mechanism.

[0006] Furthermore, the mounting base includes a base plate, a storage base, and a support plate.

[0008] Furthermore, the frame includes a vertical plate, an L-shaped mounting base, and a semi-circular plate. The vertical plate is integrally connected to both ends of the bottom of the L-shaped mounting base, and the top of the vertical plate near the roll bag assembly is provided with an outwardly protruding semi-circular plate.

[0009] Furthermore, the sealing mechanism consists of two symmetrical sealing assemblies, each including a mounting frame, a pump base, a hydraulic push rod, a connecting rod, a heating plate, a vacuum suction cup, a vacuum pump, a cutting blade, a control chip, and a temperature sensor. A mounting frame is positioned above the horizontal plate of the L-shaped mounting base, and the longitudinal section of the mounting frame is U-shaped. The two mounting frames are symmetrically arranged on both sides of the roll-up assembly. A pump base with a top opening is located at the center of the mounting frame on the side furthest from the roll-up assembly, and a vacuum pump is installed inside the pump base. Heating plates are embedded in the two horizontal plates of the mounting frame on the side closest to the roll-up assembly. Vacuum suction cups are evenly arranged on the vertical plate. Both ends of the mounting frame away from the roll bag assembly are fixed with connecting rods, which pass through the vertical plate of the L-shaped mounting base. A hydraulic push rod is fixed at the center of the vertical plate of the L-shaped mounting base away from the roll bag assembly, and the output end of the hydraulic push rod passes through the L-shaped mounting base and connects to the pump base. A cutting blade is connected to the bottom of one of the mounting frames near the roll bag assembly, and a corresponding knife groove is opened at the bottom of the other mounting frame near the roll bag assembly. A temperature sensor is installed inside the mounting frame near the heating plate, and a control chip and a circuit breaker are installed inside the mounting frame.

[0010] Furthermore, the bag feeding mechanism consists of two mutually symmetrical bag feeding assemblies, and the bag feeding assembly includes a conveying motor, a conveying roller, a sleeve, and a transmission gear. The two ends of the conveying roller are respectively rotatably connected to two semicircular plates on a frame, and a transmission gear is connected to one semicircular plate at one end of the conveying roller. A conveying motor is installed at the end of one of the conveying rollers away from the transmission gear, and the output end of the conveying motor is connected to the conveying roller. The transmission gears at the ends of the two conveying rollers mesh with each other, and sleeves are connected to the outer sides of the two conveying rollers by springs, and the two sleeves abut against each other.

[0011] Furthermore, the mounting frame includes an L-shaped plate, a connecting plate, and fastening bolts. The connecting plates are movably inserted into both ends of the vertical plate of the L-shaped plate, and a parallel plate is fixed to the top of the connecting plate. The parallel plate is parallel to the horizontal plate of the L-shaped plate, and an electric heating plate is embedded on the side of the horizontal plate and the parallel plate near the roll bag assembly. Fastening bolts are installed on the vertical plate of the L-shaped plate near the connecting plate, and the ends of the fastening bolts abut against the connecting plate.

[0012] Furthermore, the vacuum suction cup is integrally connected to a connecting pipe on the side away from the bag rolling assembly, and the connecting pipe passes through the vertical plate of the mounting frame and extends into the pump base. Multiple connecting pipes are connected to each other through a connecting pipe, and the suction end of the vacuum pump is connected to the connecting pipe through a corrugated pipe. A return spring is wound around the outside of the connecting pipe between the vacuum suction cup and the vertical plate of the mounting frame.

[0013] The beneficial effects of this utility model are: 1. This application achieves automated collaboration across multiple processes: Firstly, the bag-feeding stage utilizes dual conveyor rollers and transmission gears to achieve synchronous reverse rotation. The sleeves on the outer sides of the conveyor rollers are spring-loaded, allowing for adaptive clamping of fruit bags of varying thicknesses and stable upward transport, replacing manual bag handling and feeding. Secondly, the bag-opening stage uses a hydraulic push rod to drive the installation frame, which, in conjunction with a vacuum pump, controls vacuum suction cups to adhere to both sides of the fruit bag. The separation of the installation frame automatically opens the fruit bag, eliminating the need for manual bag opening and preventing damage to young fruit from manual operation. Thirdly, the sealing and cutting stages are integrated into the sealing mechanism. The heat sealing and cutting actions are completed in conjunction, eliminating the need for separate manual operation. Throughout the process, the operator only needs to adjust the equipment position using the handle and feed the fruit into the already opened fruit bag, significantly surpassing the efficiency of manual labor and traditional tools.

[0014] 2. This application achieves multi-specification fruit bag adaptation through an adjustable roll bag assembly: a groove is opened on the top of the winding roller, and the slider can slide freely along the groove. With the help of the mounting clip, it can clamp roll thermoplastic fruit bags of different widths without changing equipment parts due to the bag specifications. It adapts to the bagging needs of various fruits such as apples, pears, and citrus. The connecting plate of the mounting frame can slide up and down in the L-shaped plate, driving the parallel plate to move up and down and adjust the distance between it and the horizontal plate of the L-shaped plate to adapt to different sizes of fruits. The fastening bolts can quickly fix the position of the connecting plate, ensuring that the parallel plate and the horizontal plate of the L-shaped plate are relatively stable after adjustment, ensuring uniform pressure during heat sealing by the electric heating plate and improving the sealing effect.

[0015] 3. The sealing mechanism of this application ensures sealing effect through precise heat sealing and intelligent temperature control: the electric heating plate embedded in the horizontal plate of the mounting frame can perform heat-press sealing at the joint of the fruit bag, and the sealing strength is far higher than that of traditional mechanical pressing; at the same time, the mounting frame integrates a temperature sensor, a control chip and a circuit breaker. The temperature sensor monitors the temperature of the electric heating plate in real time, and the control chip automatically adjusts the heating power according to the material of the fruit bag. When the temperature exceeds the safety threshold, the circuit breaker automatically cuts off the power, which not only avoids the fruit bag from being burned by excessive temperature, but also prevents the seal from falling off due to insufficient temperature, thus ensuring the sealing performance and safety.

[0021] Please see Figure 1 and Figure 3 The frame 8 includes a vertical plate 801, an L-shaped mounting base 802, and a semi-circular plate 803. The vertical plate 801 is integrally connected to both ends of the bottom of the L-shaped mounting base 802, and the top of the vertical plate 801 near the bag rolling assembly 6 is provided with an outwardly protruding semi-circular plate 803. The vertical plate 801 and the L-shaped mounting base 802 are integrally connected, which has high structural strength and strong load-bearing capacity, and can provide solid support for the bag feeding mechanism 7 and the bag sealing mechanism 9. The protruding design of the semi-circular plate 803 is well adapted to the conveying roller 702 of the bag feeding mechanism 7, which facilitates the rotation and installation of the conveying roller 702.

[0022] Please see Figure 1 and Figure 2The sealing mechanism 9 consists of two symmetrical sealing assemblies, each including a mounting frame 901, a pump base 902, a hydraulic push rod 903, a connecting rod 904, a heating plate 905, a vacuum suction cup 906, a vacuum pump 907, a cutting blade 909, a control chip 910, and a temperature sensor 911. The mounting frame 901 is positioned above the horizontal plate of the L-shaped mounting base 802, and its longitudinal section is U-shaped. The two mounting frames 901 are symmetrically positioned on both sides of the roll-up assembly 6, with the mounting frames 901 located away from the roll-up assembly. A pump base 902 with a top opening is provided at the center of one side of the bag rolling assembly 6, and a vacuum pump 907 is installed inside the pump base 902. Heating plates 905 are embedded in the two horizontal plates of the mounting frame 901 near the side of the bag rolling assembly 6, and vacuum suction cups 906 are evenly arranged on the vertical plate of the mounting frame 901. Connecting rods 904 are fixed at both ends of the mounting frame 901 away from the bag rolling assembly 6, and the connecting rods 904 pass through the vertical plate of the L-shaped mounting base 802.

[0023] Please see Figure 1 and Figure 3The bag feeding mechanism 7 consists of two mutually symmetrical bag feeding assemblies, each including a conveyor motor 701, a conveyor roller 702, a sleeve 7021, and a transmission gear 703. The two ends of the conveyor roller 702 are rotatably connected to two semicircular plates 803 on a frame 8, and a transmission gear 703 is connected to one of the semicircular plates 803 at one end of the conveyor roller 702. The conveyor motor 701 is mounted on the end of one of the conveyor rollers 702 away from the transmission gear 703, and the output end of the conveyor motor 701 is connected to the conveyor roller 702. The transmission gears 7021 at the ends of the two conveyor rollers 702 are connected to each other. The two conveyor rollers 702 are interlocked, and the outer sides of each roller are connected to sleeves 7021 via springs. The two sleeves 7021 abut against each other, and the transmission gears 703 mesh with each other to achieve synchronous and opposite rotation of the two conveyor rollers 702, ensuring that the bag is subjected to uniform force during conveying and avoiding bag wrinkles or deviation. The spring-connected sleeves 7021 have elastic adjustment capabilities and can automatically adapt the spacing according to the bag thickness, always maintaining an appropriate clamping force on the bag and effectively preventing slippage. The conveyor motor 701 provides a stable power source to realize automatic bag conveying and improve the automation level of bagging operations.

[0024] Please see Figure 3 and Figure 4 The mounting frame 901 includes an L-shaped plate 9011, a connecting plate 9012, and fastening bolts 9014. The connecting plate 9012 is movably inserted into both ends of the vertical plate of the L-shaped plate 9011, and a parallel plate 9013 is fixed to the top of the connecting plate 9012. The parallel plate 9013 is parallel to the horizontal plate of the L-shaped plate 9011, and heating plates 905 are embedded on the side of both the horizontal plate of the L-shaped plate 9011 and the side of the parallel plate 9013 closest to the roll bag assembly 6. The vertical plate of the L-shaped plate 9011 has heating plates 905 positioned near the connecting plate 9012. The connecting plate 9012 is equipped with a fastening bolt 9014, the end of which is pressed against the connecting plate 9012. The connecting plate 9012 can slide up and down within the L-shaped plate 9011, causing the parallel plate 9013 to move up and down, adjusting the distance between it and the horizontal plate of the L-shaped plate 9011 to accommodate fruits of different sizes. The fastening bolt 9014 can fix the position of the connecting plate 9012, ensuring that the parallel plate 9013 and the horizontal plate of the L-shaped plate 9011 are relatively stable after adjustment, ensuring uniform pressure during heat sealing of the heating plate 905 and improving the sealing effect.

[0025] Please see Figure 3 and Figure 4A connecting pipe 9062 is integrally connected to the side of the vacuum suction cup 906 away from the bag rolling assembly 6. The connecting pipe 9062 passes through the vertical plate of the mounting frame 901 and extends into the pump base 902. Multiple connecting pipes 9062 are connected by a connecting pipe 908. The suction end of the vacuum pump 907 is connected to the connecting pipe 908 through a corrugated pipe 9071. A return spring 9061 is wound around the outside of the connecting pipe 9062 between the vacuum suction cup 906 and the vertical plate of the mounting frame 901. The connecting pipe 908 connects multiple connecting pipes 9062, so that the vacuum pump 907 can simultaneously provide air to all vacuum suction cups 906. Negative pressure ensures consistent suction force from each suction cup, guaranteeing even expansion of the bag. The corrugated tube 9071 has excellent telescopic and bending properties, accommodating the movement of the connecting tube 9062 and preventing pipe breakage due to pulling. In the initial state, the vacuum suction cup 906 extends out of the mounting frame 901 under the action of the return spring 9061, closer to the bag than the heating plate 905, allowing for stable suction of the bag and opening to both sides. During heat sealing, the heating plates 905 on both sides press against each other, at which point the return spring 9061 is compressed, and the vacuum suction cup 906 retracts into the internal space of the mounting frame 901, without obstructing the pressing.

[0026] Detailed Implementation: In use, according to the width of the bag, slide the slider 603 along the groove 6022 of the take-up roller 602, adjust the spacing of the mounting clips 604 and fix the bag roll, and wind the entire roll of thermoplastic fruit bag onto the take-up roller 602. Use the mounting clips 604 to clamp both ends of the roll of bag. The take-up motor 601 works to drive the take-up roller 602 to rotate, winding the bag onto the take-up roller 602. Manually guide the starting end of the bag to the sleeve 7021 of the bag feeding mechanism 7. The spring makes the sleeve 7021 tightly clamp the bag. Start the conveyor motor 701 to drive one conveyor roller 702 to rotate. Through the meshing of the transmission gear 703, it drives the other conveyor roller 702 to rotate synchronously in the opposite direction, smoothly conveying the bag to the sealing mechanism 9. After the bag is in place, the control chip 910 starts the sealing mechanism. The air pump 907, through the bellows 9071, connecting pipe 908, and connecting pipe 9062, causes the vacuum suction cup 906 to adhere to both sides of the bag. The hydraulic push rod 903 pulls the mounting frame 901 to move to both sides along the connecting rod 904, opening the bag. After the fruit is placed in, the hydraulic push rod 903 works, causing the two mounting frames 901 to move closer together. The return spring 9061 is compressed, and the fruit is located in the space between the two mounting frames 901. The heating plate 905 heats and seals the bag. The temperature sensor 911 provides real-time temperature feedback to the control chip 910 for adjustment. At the same time, the cutting blade 909 and the cutting groove 9091 work together to cut the bag. After cutting, the hydraulic push rod 903 drives the mounting frame 901 to return to its original position, the vacuum suction cup 906 pops out, and the bag feeding mechanism 7 continues to transport the bag, repeating the operation.
