Description

Technical Field

[0001] This invention relates to the field of meal wrapping machine technology, and specifically to a meal wrapping machine. Background Technology

[0002] Grape leaf wraps are a traditional dish in the Mediterranean, Middle East and Balkans. Also known as dormades or salma, it is a dish made by wrapping seasoned fillings in treated grape leaves and then cooking them. The whole process can be divided into steps such as preparing the leaves, preparing the fillings, wrapping and shaping, and cooking. In the wrapping and shaping step, you need to take a prepared grape leaf, lay it flat on a cutting board or in your palm, place the filling near the bottom of the leaf stem, then fold the left and right sides of the leaf towards the middle, and then start from the bottom of the leaf stem and roll the leaf towards the tip until it is rolled into a compact small cylinder. However, the existing steps for making grape leaf-wrapped rice are all done manually, requiring manual handling of steps such as conveying, first-direction leaf rolling, and second-direction leaf rolling. This is not suitable for mass production in industries such as canning, resulting in low work efficiency and high labor intensity for workers.

[0003] Therefore, the present invention provides a meal wrapping machine to solve the above problems. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a rice wrapping machine to solve the problem that the production steps of the existing grape leaf rice wrapping are all done manually, resulting in low work efficiency.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A lunchbox machine includes a water tank conveyor, a conveying mechanism, a transfer mechanism, and a leaf roller. There are two transfer mechanisms, which are fixedly connected to both sides of the leaf roller. The leaf roller is located in the middle of the two transfer mechanisms, such that the inlet and outlet ends of the leaf roller are respectively connected to the two transfer mechanisms. The transfer mechanism connected to the inlet end of the leaf roller is connected to one end of the conveying mechanism. The transfer mechanism feeds the material in the conveying mechanism into the inlet end of the leaf roller. The other end of the conveying mechanism is connected to the water tank conveyor for material transfer. The other transfer mechanism sends the material in the leaf roller out from the outlet end. Through the above technical solution, this rice wrapping machine operates as a fully automated assembly line. The water trough conveyor soaks and transports the grape leaves over long distances, with the leaves floating inside to prevent wrinkling and ensure transport stability. The conveying mechanism scoops up the grape leaves and transports them over short distances, again avoiding wrinkling. The first transfer mechanism precisely picks up the grape leaves and feeds them into the leaf roller, with stable and precise picking and unloading. The leaf roller then rolls the leaves, and the second transfer mechanism precisely picks up the rolled rice wrap and delivers it, completing the final output. This achieves full automation from conveying, feeding, rolling to unloading, eliminating the need for manual intervention in intermediate steps. It enables high-precision material conveying and docking, allowing for stable continuous production and is suitable for mass production in the industry.

[0006] Preferably, the water tank conveyor includes an extension plate, a propeller, a liquid level sensor, a water inlet, a water distribution platform, a water distribution trough, and a water tank platform. The water distribution platform is fixedly connected inside the water tank platform, forming a water flow channel between the water distribution platform and the water tank platform. A propeller is installed on the lower side of the water tank platform, and the propeller is inclined and located inside the water flow channel. An extension plate is integrally formed at one end of the water distribution platform, forming a leaf picking channel between the extension plate and the water tank platform. A water inlet is provided through between the upper and lower sides of the water distribution platform. A water distribution trough is provided on the upper side of the water distribution platform, extending into the water flow channel. The upper end of the water inlet extends into the water distribution trough. A liquid level sensor is installed inside the water tank platform, and the monitoring end of the liquid level sensor is located inside the water flow channel. With the above technical solution, some water will be lost as the first conveying mechanism picks up the grape leaves. Therefore, water is continuously supplied from the water inlet to the water distribution tank and water flow channel to ensure that the liquid level remains stable within a certain range. The liquid level sensor can detect the liquid level in real time. The inclined propeller acts directly on the water body and uses fluid kinetic energy to push the grape leaves, avoiding direct contact and compression of the material by mechanical parts, which greatly reduces mechanical damage during the conveying process.

[0007] Preferably, the conveying mechanism includes a support frame, a conveyor belt, conveyor rollers, and a first motor. The lower end of the support frame is inclined downward and the upper end is horizontal. Conveyor rollers are linearly arrayed and rotate between the upper and lower ends of the support frame. A conveyor belt is sleeved between the conveyor rollers, such that the lower half of the conveyor belt is inclined downward and the upper half is horizontal. The first motor is fixedly connected to the upper side of the support frame. The output end of the first motor rotates through the support frame and is fixedly connected to the conveyor roller located at the end of the support frame. The width of the support frame is smaller than the width of the leaf picking channel, so that the lower end of the support frame and the lower half of the conveyor belt in the conveying mechanism are located inside the leaf picking channel, and the propeller faces the support frame. Through the above technical solution, the support frame is not a simple straight or inclined type, but a zigzag structure with the lower end inclined downward and the upper end horizontal. This makes the conveyor belt present a combination of "inclined section + horizontal section". The lower half is immersed in water and is responsible for receiving and picking up materials, while the upper half is exposed above the water surface and is responsible for material output and initial drainage. The width of the support frame is smaller than the width of the leaf picking channel, which means that the conveying mechanism can be inserted into the leaf picking channel of the conveying mechanism, and the two form a partially overlapping junction area to accurately receive grape leaves.

[0008] Preferably, the transfer mechanism includes a housing, a second motor, a shaped column, a first gear, a ball bearing, a second gear, a top column, a rotating cylinder, a square frame, a spring, a limiting column, and a first support plate. The housing is fixedly connected to the leaf roller. The second motor is fixedly connected to the side of the housing. The output end of the second motor rotates and passes through the housing, and then is fixedly connected to the first gear. The first gear and the second gear mesh. The second gear is fixedly sleeved on the upper end of the rotating cylinder. The rotating cylinder rotates inside the housing. Two square frames move up and down inside the rotating cylinder. Two limiting columns are fixedly connected to the lower side of the interior of the rotating cylinder. The limiting columns move up and down through the square frames. A spring is fixedly connected between the square frames and the rotating cylinder, and the limiting columns are located inside the spring. A first support plate is arranged in a straight line at the lower end of the square frames. The first support plate is horizontally arranged. The directions of the first support plates on the two square frames are opposite. A top column is fixedly connected to the upper end of the square frames. A ball bearing rolls on the upper end of the top column. The ball bearing rolls on the lower end surface of the shaped column. The upper end of the shaped column is fixedly connected to the upper side of the interior of the housing. The irregularly shaped column includes a column body, a concave surface, a first plane, a second plane, and a convex surface. The upper end of the column body is fixedly connected to the upper inner side of the outer shell. The lower end of the column body is provided with a concave surface, a first plane, a second plane, and a convex surface. The concave surface is located between one end of the first plane and the second plane, and the convex surface is located between the other end of the first plane and the second plane. The ball rolls between the concave surface, the first plane, the second plane, and the convex surface. The first support plate rests on the upper side of the upper end of the conveyor belt; Through the above technical solution, the lower end face of the irregular column forms a closed loop track, which is composed of a concave surface, a convex surface, a first plane and a second plane to form a three-dimensional track. When the ball rolls in it, it will drive the top column to move up and down. The square frame is penetrated by the limiting column and can only slide up and down, but cannot rotate. The spring is always in a compressed state, so that the ball is in close contact with the lower end face of the irregular column, ensuring that the ball will not leave the track. It also causes one square frame to push down and the other square frame to retract upward. The two sets of support plates are in opposite directions and work alternately. When the first set of first support plates is transporting materials, the second set of first support plates is already receiving materials. This realizes the continuous input of materials and the intermittent, orderly output, which perfectly matches the process requirements of the leaf roller that requires intermittent feeding and avoids the accumulation of materials at the end of the conveyor belt. In summary, the transfer mechanism can realize automatic material picking, transfer and unloading. It solves the problems of breakage and timing matching when transferring materials from the conveyor belt to the leaf roller.

[0009] Preferably, the leaf curler includes a feed bin, a fifth motor, a peristaltic pump, a discharge nozzle, a rotating frame, a first-angle leaf curling mechanism, a second support plate, a second-angle leaf curling mechanism, and a vertical frame. The upper end of the vertical frame is fixedly connected to the fifth motor, and the output end of the fifth motor is fixedly connected to the rotating frame downwards. The rotating frame rotates and passes through the vertical frame. The lower end of the rotating frame is fixedly connected to the second support plate in a linear array. Two sets of first-angle leaf curling mechanisms are installed at the lower end of the rotating frame. The second support plate is located between the two sets of first-angle leaf curling mechanisms. The first-angle leaf curling mechanisms rotate along a first direction... The rotating frame is equipped with two sets of second-angle leaf-rolling mechanisms at the lower end of the rotating frame. The second support plate is located in the middle of the two sets of second-angle leaf-rolling mechanisms. The second-angle leaf-rolling mechanisms roll up the rice leaves along the second direction. The first direction and the second direction are perpendicular to each other. A rice feed box is fixedly connected to the upper end of the upright frame. A conveying pipe is fixedly connected to the lower side of the rice feed box, and the other end of the conveying pipe is connected to the feed end of the peristaltic pump. The peristaltic pump is fixedly connected to the upper end of the rotating frame. A discharge nozzle is fixedly connected to the discharge end of the peristaltic pump. The discharge nozzle is vertically downward and faces the second support plate. The transfer mechanism moves and crosses with the second support plate after the first support plate is transferred into the leaf roller. Through the above technical solution, the filling in the rice feed box enters the peristaltic pump through the conveying pipe and is finally sprayed vertically downward from the discharge nozzle, landing on the grape leaves on the second support plate below. The first support plate of one of the transfer mechanisms and the second support plate of the leaf roller move to cross each other to realize the transfer of grape leaves. The first angle leaf roller and the second angle leaf roller roll the grape leaves from the first direction and the second direction, which are perpendicular to each other, respectively, realizing the bidirectional rolling of grape leaves and realizing the function of wrapping rice in grape leaves. The first support plate of the other transfer mechanism and the second support plate of the leaf roller use a moving cross to transfer the finished rice wrapped in grape leaves. This realizes the receiving of grape leaves and the conveying of finished rice wrapped in grape leaves, and also avoids the material damage that may be caused by the robot arm picking or pushing down, thus ensuring the integrity of the rice leaves and the wrapped rice.

[0010] Preferably, the first angle leaf-rolling mechanism includes a leaf-rolling rod, a roller, a fourth motor, a fourth gear, a roller tube, a toothed plate, a limiting wheel, a slide, a leaf-rolling mechanism support frame, and an electric push rod. The leaf-rolling mechanism support frame is fixedly connected to the lower end of the rotating frame. A slide is slidably installed inside the leaf-rolling mechanism support frame. The fourth motor is fixedly connected to the side of the slide. The output end of the fourth motor rotates through the slide and is fixedly connected to a roller. The roller rolls inside the leaf-rolling mechanism support frame. A roller tube rotates through the slide. Both ends of the roller tube are fixedly connected. A fixed connection limit wheel is connected, and the limit wheel rolls inside the leaf-rolling mechanism support frame. The leaf-rolling mechanism support frame is sandwiched between two limit wheels. A fourth gear is fixedly passed through the middle end of the roller tube. The fourth gear meshes with the toothed plate. The toothed plate is fixedly connected inside the leaf-rolling mechanism support frame. An electric push rod is fixedly connected to the side of the carriage. A leaf-rolling rod is rotatably installed at the output end of the electric push rod. The leaf-rolling rod moves laterally through the roller tube. The leaf-rolling rod faces the second support plate. The diameter of the end of the leaf-rolling rod near the second support plate is increased and a leaf-rolling groove is provided. The blade roller and the second support plate are at the same height; Through the above technical solution, the slide is installed in the support frame of the leaf-rolling mechanism. The rollers are driven by the fourth motor to rotate, so that the entire slide can move back and forth. The structure of the limiting wheel and the two ends of the roller tube ensures the stability of the slide when it moves, preventing tilting or slipping. When the slide moves, the fourth gear fixed on the roller tube meshes with the fixed tooth plate, forcing the roller tube to rotate while moving. The roller tube drives the leaf-rolling rod to rotate. The leaf-rolling rod can roll up the grape leaves, realizing the function of rolling grape leaves in the first direction. The electric push rod can drive the leaf-rolling rod to move, so that the leaf-rolling rod can get close to the grape leaves, ensuring that the grape leaves are stuck in the leaf-rolling groove. It can also make the leaf-rolling rod withdraw from the finished rice after the rice is rolled.

[0011] Preferably, the second angle leaf-rolling mechanism includes a third motor, a third gear, a swing frame, and a swing rod. The third gear rotates within the rotating frame via a rotating shaft. There are two third gears that mesh with each other. Both third gears are coaxially fixedly connected to the swing frame. The front end of the swing frame is located below the second support plate. The front end of the swing frame is fixedly connected to the swing rod. The swing rod is in a vertical state and its top end is at the same height as the second support plate. After the swing rod rotates to a horizontal position, it is located above the second support plate. The third motor is fixedly connected to the side of the rotating frame, and the output end of the third motor is fixedly connected to the rotation center of one of the third gears. Through the above technical solution, the two third gears mesh with each other, ensuring that the movement of the two swing frames is synchronous and opposite in direction. The two swing rods will reach the predetermined position at the same time, ensuring the symmetry and consistency of the rolling action and avoiding rolling deviation. The swing rods are initially in a vertical state and do not occupy the space above the second support plate at all. This allows the grape leaves to be placed freely on the second support plate and the swing rods. When the swing rods follow the rotation of the swing frame, the swing rods can push the two pairs of sides of the grape leaves to roll up towards the middle, realizing the rolling function in the second direction. The first-angle leaf-rolling mechanism uses forward and backward rolling, while the second-angle leaf-rolling mechanism uses left and right swing rolling. The two movements are perpendicular to each other and do not interfere with each other. Both can complete their actions within a compact space, together achieving bidirectional rolling and completing the rice-rolling function.

[0012] The beneficial effects of this invention are as follows: 1. The water tank conveyor wets and transports grape leaves over long distances, and automatically detects water level and replenishes water to ensure the stability of the grape leaves as they float in the water tank conveyor and are transported with the water flow, which can avoid wrinkling of the grape leaves and ensure transportation stability. 2. The conveying mechanism scoops up the grape leaves and transports them over short distances, avoiding wrinkling of the grape leaves; 3. The first transfer mechanism accurately picks up the grape leaves and precisely feeds them into the leaf roller; both the picking up and placing are stable and precise. 4. The leaf-rolling device performs the leaf-rolling operation and also turns and conveys the finished rice wraps. 5. The second transfer mechanism accurately picks up the rolled meal pack and places it precisely on the second conveyor mechanism before sending it out, completing the final discharge. This achieves full automation from conveying, feeding, rolling to unloading, eliminating the need for manual intervention in intermediate links. It enables high-precision material conveying and docking, allowing for stable continuous production and is suitable for mass production in the industry.

[0013] In summary, this device features two sets of transfer mechanisms that allow for simultaneous feeding and discharging without interference, significantly improving production efficiency. The rolled rice rolls are very soft and easily deformed; however, the dedicated transfer mechanism handles the loading and unloading, rather than pushing them directly. This ensures that the rice rolls maintain their cylindrical shape as they are transferred from the roller to the discharge conveyor belt, guaranteeing product quality. Therefore, the entire process from conveying, feeding, rolling to unloading is fully automated, eliminating the need for manual intervention in intermediate stages. It achieves high-precision material handling and docking, enabling stable continuous production and making it suitable for mass production in industry. Attached Figure Description

[0027] The following will refer to the attached reference. Figures 1 to 12 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0028] As attached Figure 1 -Appendix Figure 12As shown, a rice wrapping machine includes a water trough conveyor 1, a conveying mechanism 2, a transfer mechanism 3, and a leaf roller 4. There are two transfer mechanisms 3, which are fixedly connected to both sides of the leaf roller 4, with the leaf roller 4 located in the middle of the two transfer mechanisms 3. The inlet and outlet ends of the leaf roller 4 are respectively connected to the two transfer mechanisms 3. The leaf roller 4 wraps grape leaves and fillings. One transfer mechanism 3 accurately puts the grape leaves into the leaf roller 4, and the other transfer mechanism 3 sends the finished grape leaf-wrapped rice out of the leaf roller 4. The transfer mechanism 3 connected to the inlet end of the leaf roller 4 is connected to the conveying mechanism 2. The transfer mechanism 3 sends the grape leaf material in the conveying mechanism 2 into the inlet end of the leaf roller 4. The conveying mechanism 2 is connected to the water trough conveyor 1 to transfer the grape leaf material. The grape leaves are placed on the water in the water trough conveyor 1 to float, so as to spread out and transport over long distances. A controller 5 is fixedly connected to the leaf roller 4, and the input terminal of the controller 5 is electrically connected to the output terminal of an external mains power supply. The working principle of the water tank conveyor 1, the conveying mechanism 2, the transfer mechanism 3, and the leaf roller 4 is as follows: grape leaves are placed in the water tank conveyor 1 for water flow transportation. When the grape leaves reach the end of the water tank conveyor 1, the conveying mechanism 2 picks up the grape leaves and transports them to the first transfer mechanism 3. The first transfer mechanism 3 then sends the grape leaves to the leaf roller 4 for leaf rolling and wrapping. After wrapping is completed, the second transfer mechanism 3 receives the wrapped product and sends it out, thus completing the conveying and wrapping functions.

[0029] As attached Figure 1 and attached Figure 3As shown, the water tank conveyor 1 includes an extension plate 101, a propeller 102, a liquid level sensor 103, a water inlet 104, a water distribution platform 105, a water distribution trough 106, and a water tank platform 107. The water distribution platform 105 is fixedly connected inside the water tank platform 107, forming a water flow channel between the water distribution platform 105 and the water tank platform 107. Water flows in the water flow channel, and grape leaves float on the water flow. The propeller 102 is installed on the lower side of the water tank platform 107 and is inclined. Propeller 102 is located within the water flow channel. The input of propeller 102 is electrically connected to the output of controller 5. Specifically, propeller 102 includes a motor and blades. The output of the motor fixes the blades and drives them to rotate. The motor is located on the lower side of the water tank platform 107 and does not contact the water. The blades are located within the water flow channel. The input of the motor is electrically connected to the output of controller 5. When the motor drives the blades to rotate, it propels the water to flow. That is, when the motor in propeller 102 is energized, it drives the blades to rotate, thereby propelling the water flow. One end of the water distribution platform 105 is integrally formed with an extension plate 101, which forms a leaf-collecting channel with the water tank platform 107. The leaf-collecting channel is connected to the water flow channel. A water inlet hole 104 is provided through the upper and lower sides of the water distribution platform 105. A water distribution trough 106 is provided on the upper side of the water distribution platform 105, which extends into the water flow channel. Specifically, the water distribution trough 106 has multiple water outlets, with no fewer than two, so that the water flow will not be concentrated when the water outlets are connected to the water flow channel. Instead, the water is diverted into the water flow channel, where the flow rate is slower, avoiding water turbulence and making the flow of grape leaves more stable. The upper end of the water inlet 104 extends into the water distribution trough 106, and the lower end of the water inlet 104 is fixedly connected to a water pipe. After the water pipe is connected to the external water supply equipment, it continuously supplies water to the water inlet 104 and the water distribution trough 106. A liquid level sensor 103 is installed in the water tank platform 107. The monitoring end of the liquid level sensor 103 is located in the water flow channel, and the liquid level sensor 103 is electrically connected to the controller 5. The working method of the water tank conveyor 1 is as follows: the controller 5 controls the propeller 102 to be powered on, so as to start the propeller 102 installed on the lower side of the water tank platform 107 and inclined. Since the propeller is located in the water flow channel formed between the water distribution platform 105 and the water tank platform 107, its rotation will generate thrust, drive the water in the channel to flow quickly, and form a directional water flow. After the grape leaves are put into the water, they move with the water flow. When they flow through the leaf picking channel between the extension plate 101 and the water tank platform 107, they can be received by the conveying mechanism 2. When the water in the water flow channel decreases due to the grape leaves being carried out, the liquid level sensor 103 detects the drop in water level and immediately issues an alarm to remind the staff to replenish water in time. The staff can control the external water supply equipment to replenish water into the water inlet 104. The water first enters the water inlet 104, then enters the water distribution tank 106 for diversion, and finally flows into the water flow channel below. The design of the water distribution tank 106 plays a role in buffering and uniform water distribution, ensuring that the replenished water flow is stable and will not cause a violent impact on the main water flow channel.

[0030] As attached Figure 1 and attached Figure 4 As shown, the conveying mechanism 2 includes a support frame 201, a conveyor belt 202, a conveyor roller 203, and a first motor 204. The lower end of the support frame 201 is inclined downward and the upper end is horizontal. The conveyor roller 203 is linearly arranged and rotates between the upper and lower ends of the support frame 201. The conveyor belt 202 is sleeved between the conveyor rollers 203. When the conveyor roller 203 rotates, it drives the conveyor belt 202 to rotate cyclically. The lower half of the conveyor belt 202 is inclined downward and the upper half is horizontal. The first motor 204 is fixedly connected to the upper side of the support frame 201. The output end of the first motor 204 rotates and passes into the support frame 201 and is fixedly connected to the conveyor roller 203 located at the end of the support frame 201. The input end of the first motor 204 is electrically connected to the output end of the controller 5. The width of the support frame 201 is smaller than the width of the leaf picking channel, so that the lower end of the support frame 201 and the lower half of the conveyor belt 202 in the conveying mechanism 2 are located in the leaf picking channel, and the propeller 102 faces the support frame 201. The working method of the conveying mechanism 2 is as follows: Since the width of the support frame 201 is smaller than the leaf picking channel, the lower inclined section of the conveying mechanism 2 extends into the leaf picking channel between the extension plate 101 of the conveying mechanism 1 and the water tank platform 107. That is, the lower half of the conveying mesh belt 202, the lower end of the support frame 201 and a part of the lower conveying roller 203 are placed in the leaf picking channel. The propeller 102 of the water tank conveyor 1 is inclined and faces the support frame 201. The rotation of the propeller 102 makes the water flow direction in the water flow channel point to the water tank conveyor 1. Under the push of the water flow, the grape leaves pass through the leaf picking channel and fall directly onto the lower inclined section of the conveying mesh belt 202. At the same time, the controller 5 controls the first motor 204 to be powered on and started. The first motor 204 drives the conveyor roller 203 to rotate, and the conveyor roller 203 drives the conveyor belt 202 to rotate in a cycle. The grape leaves falling on the conveyor belt 202 move upward with the conveyor belt 202. Since the conveyor belt 202 is a mesh structure, it reduces the obstruction to the water flow in the leaf picking channel and the water flow channel. Moreover, during the process of material climbing, most of the water will flow back to the water flow channel of the conveying mechanism 1 through the mesh due to gravity.

[0031] As attached Figure 1 Appendix Figure 2 and attached Figure 5As shown, the transfer mechanism 3 includes a housing 301, a second motor 302, a shaped column 303, a first gear 304, a ball bearing 305, a second gear 306, a top column 307, a rotating cylinder 308, a square frame 309, a spring 3010, a limiting column 3011, and a first support plate 3012. The housing 301 is fixedly connected to the leaf roller 4. The second motor 302 is fixedly connected to the side of the housing 301. The input end of the second motor 302 is electrically connected to the output end of the controller 5. The output end of the second motor 302 rotates and passes into the housing 301, where it is fixedly connected to the first gear 304. The first gear 304 meshes with the second gear 306. The second gear 306 is fixedly sleeved on the upper end of the rotating cylinder 308. The rotating cylinder 308 rotates inside the housing 301. The rotating cylinder 308 has two square frames 309 that move up and down. Two limiting posts 3011 are fixedly connected to the lower side of the inner side of the rotating cylinder 308. The limiting posts 3011 move up and down through the square frames 309. A spring 3010 is fixedly connected between the square frames 309 and the rotating cylinder 308, and the limiting posts 3011 are located inside the spring 3010. A first support plate 3012 is arranged in a straight line at the lower end of the square frame 309. The first support plate 3012 is horizontally set. The first support plates 3012 on the two square frames 309 are oriented in opposite directions. A top post 307 is fixedly connected to the upper end of the square frame 309. A ball bearing 305 rolls on the upper end of the top post 307. The ball bearing 305 rolls on the lower end surface of the irregular column 303. The upper end of the irregular column 303 is fixedly connected to the upper side of the inner side of the outer shell 301. See appendix Figure 6 The irregular column 303 includes a column body 3031, a concave surface 3032, a first plane 3033, a second plane 3034, and a convex surface 3035. The upper end of the column body 3031 is fixedly connected to the upper inner side of the outer shell 301. The lower end of the column body 3031 is provided with a concave surface 3032, a first plane 3033, a second plane 3034, and a convex surface 3035. The concave surface 3032 is located between one end of the first plane 3033 and the second plane 3034, and the convex surface 3035 is located between the other end of the first plane 3033 and the second plane 3034. The ball 305 rolls between the concave surface 3032, the first plane 3033, the second plane 3034, and the convex surface 3035. The first support plate 3012 rests on the upper side of the upper end of the conveyor belt 202; The working principle of the transfer mechanism 3 is as follows: the controller 5 controls the second motor 302 to start, the second motor 302 drives the first gear 304 to rotate, the first gear 304 drives the second gear 306 to rotate through inter-tooth meshing, the second gear 306 drives the rotating cylinder 308 to rotate continuously inside the outer casing 301, the rotating cylinder 308 drives the square frame 309 and the top column 307 to rotate, the top column 307 is forced to move along the track along the lower end face of the irregular column 303 by the ball bearings 305, while the spring 3010 continuously pushes the square frame 309 upward, so that the top column 307... 07, together with the square frame 309, will cycle through four actions: rising, translating, falling, and translating. When the ball 305 rolls onto the concave surface 3032, the top column 307 descends to its lowest point. When the ball 305 rolls onto the convex surface 3035, the top column 307 rises to its highest point. When the ball 305 rolls onto the first plane 3033 and the second plane 3034, the top column 307 maintains a certain height and translates. Because the first support plates 3012 on the two square frames 309 are oriented in opposite directions, they form an alternating working state during rotation. Initially attached Figure 1 In the state shown, the ball bearing 305 rolls onto the first plane 3033, and the first support plate 3012 falls onto the conveyor belt 202 to receive the grape leaves on the conveyor belt 202. Then the rotating cylinder 308 rotates 90°, and the ball 305 rolls a certain distance on the first plane 3033 and then rolls onto the concave surface 3032. The spring 3010 pushes the square frame 309 and the first support plate 3012 to move upward. Then the first support plate 3012 drives the grape leaf to move horizontally a certain distance and then lifts it upward. Then the rotating cylinder 308 rotates 90°, the ball 305 rolls from the concave surface 3032 to the second plane 3034, the square frame 309 and the first support plate 3012 move down, and the first support plate 3012 puts the grape leaves downward into the leaf curler 4. Then the rotating cylinder 308 rotates 90°, the ball bearing 305 rolls from the second plane 3034 to the raised surface 3035, the square frame 309 and the first support plate 3012 move down again, and the first support plate 3012 moves down away from the grape leaves, completing the laying of the grape leaves. Then, the rotating cylinder 308 rotates 90°, and the ball bearing 305 rolls from the raised surface 3035 onto the first plane 3033 and moves horizontally a certain distance. At this time, the square frame 309 and the first support plate 3012 move upward and then translate, so that the first support plate 3012 returns to the attached position. Figure 1 The state shown is the reset state; The work is carried out cyclically based on the above.

[0032] As attached Figure 1-2 and attached Figure 7-12As shown, the leaf curler 4 includes a feed bin 401, a fifth motor 402, a peristaltic pump 403, a discharge nozzle 404, a rotating frame 405, a first-angle leaf curling mechanism 406, a second support plate 407, a second-angle leaf curling mechanism 408, and a vertical frame 409. The housing 301 of the transfer mechanism 3 is fixedly connected to the vertical frame 409. The upper end of the vertical frame 409 is fixedly connected to the fifth motor 402. The input end of the fifth motor 402 is electrically connected to the output end of the controller 5. The output end of the fifth motor 402 is fixedly connected to the rotating frame 405 facing downwards. The rotating frame 405 rotates and passes through the vertical frame 409. The lower end of the rotating frame 405 is fixedly connected to the second support plate 407 in a linear array. Two sets of first-angle leaf curling mechanisms 406 are installed at the lower end of the rotating frame 405. The second support plate 407 is located between the two sets of first-angle leaf curling mechanisms 406. In the middle of 06, the first angle leaf-rolling mechanism 406 rolls up the rice leaf along the first direction. Two sets of second angle leaf-rolling mechanisms 408 are installed at the lower end of the rotating frame 405. The second support plate 407 is located in the middle of the two sets of second angle leaf-rolling mechanisms 408. The second angle leaf-rolling mechanism 408 rolls up the rice leaf along the second direction. The first direction and the second direction are perpendicular to each other. A rice feed box 401 is fixedly connected to the upper end of the upright frame 409. A conveying pipe is fixedly connected to the lower side of the rice feed box 401, and the other end of the conveying pipe is connected to the feed end of the peristaltic pump 403. The peristaltic pump 403 is fixedly connected to the upper end of the rotating frame 405. The input end of the peristaltic pump 403 is electrically connected to the output end of the controller 5. The discharge end of the peristaltic pump 403 is fixedly connected to the discharge nozzle 404. The discharge nozzle 404 is vertically downward and faces the second support plate 407. After the transfer mechanism 3 transfers the first support plate 3012 into the leaf roller 4, it moves and crosses with the second support plate 407. The leaf-rolling device 4 operates as follows: The first support plate 3012 of the transfer mechanism 3 carries the grape leaves into the leaf-rolling device 4. The first support plate 3012 and the second support plate 407 move intersectingly, meaning that they move up and down alternately in space. That is, when the first support plate 3012 descends, the material naturally falls onto the second support plate 407, completing the transfer. After the grape leaves are stably placed on the second support plate 407, the controller 5 controls the peristaltic pump 403 to start, and the filling in the feed box 401 is conveyed... After passing through the pipe and peristaltic pump 403, the material is finally sprayed vertically downwards from the discharge nozzle 404 onto the grape leaves. Then, the second angle leaf-rolling mechanism 408 first rolls the two sides of the grape leaves towards the middle, and the first angle leaf-rolling mechanism 406 then rolls them from the tip to the tail, completing the rice-rolling process. During this process, the controller 5 controls the fifth motor 402 to be powered on and drive the rotating frame 405 to rotate 180°, bringing the wrapped rice product to the first support plate 3012 of another transfer mechanism 3, completing the transfer.

[0033] As attached Figure 1-2 and attached Figure 7-12As shown, the first angle leaf-rolling mechanism 406 includes a leaf-rolling rod 4061, a roller 4062, a fourth motor 4063, a fourth gear 4064, a roller tube 4065, a toothed plate 4066, a limiting wheel 4067, a slide 4068, a leaf-rolling mechanism support frame 4069, and an electric push rod 40610. The leaf-rolling mechanism support frame 4069 is fixedly connected to the lower end of the rotating frame 405. The slide 4068 is slidably installed inside the leaf-rolling mechanism support frame 4069. The fourth motor 4063 is fixedly connected to the side of the slide 4068. The input end of the fourth motor 4063 is electrically connected to the output end of the controller 5. The output end of the fourth motor 4063 rotates through the slide 4068 and is fixedly connected to the roller 4062. The roller 4062 rolls inside the leaf-rolling mechanism support frame 4069. The roller tube 4065 rotates through the slide 4068. Both ends of the slide 4068 are fixedly connected to limit wheels 4067. The limit wheels 4067 roll within the leaf-rolling mechanism support frame 4069, and the leaf-rolling mechanism support frame 4069 is sandwiched between the two limit wheels 4067. The fourth gear 4064 passes through the middle of the roller tube 4065. The fourth gear 4064 meshes with the toothed plate 4066. The toothed plate 4066 is fixedly connected within the leaf-rolling mechanism support frame 4069. An electric push rod 40610 is fixedly connected to the side of the slide 4068. The input end of the electric push rod 40610 is electrically connected to the output end of the controller 5. The output end of the electric push rod 40610 is rotatably mounted with a leaf-rolling rod 4061. The leaf-rolling rod 4061 moves laterally through the roller tube 4065. The leaf-rolling rod 4061 faces the second support plate 407, and the diameter of the end of the leaf-rolling rod 4061 near the second support plate 407 is increased and a leaf-rolling groove is provided. The blade roller 4061 and the second support plate 407 are at the same height; The first angle leaf-rolling mechanism 406 operates as follows: Controller 5 controls the fourth motor 4063 to be energized. The fourth motor 4063 drives the roller 4062 to rotate, and the roller 4062 rolls within the leaf-rolling mechanism support frame 4069, thereby driving the slide 4068 to slide within the leaf-rolling mechanism support frame 4069. When the slide 4068 slides, it drives the roller tube 4065 to move. Simultaneously, the fourth gear 4064 meshes with the gear plate 4066. When the roller tube 4065 drives the fourth gear 4064 to move, the fourth gear 4064 and the roller tube 4065 rotate. The limiting wheels 4067 at both ends of the roller tube 4065 are positioned on the leaf-rolling mechanism support frame. The grape leaves roll inside the frame 4069, and then the controller 5 controls the electric push rod 40610 to be energized. The electric push rod 40610 pushes the leaf-rolling rod 4061 to move along the length of the roller tube 4065, so that the front end of the leaf-rolling rod 4061 approaches or moves away from the second support plate 407. At the same time, the roller tube 4065 drives the leaf-rolling rod 4061 to move and rotate. When the front end of the leaf-rolling rod 4061 approaches the second support plate 407, the grape leaves are inserted into the leaf-rolling groove of the leaf-rolling rod 4061, and the leaf-rolling rod 4061 rolls the grape leaves to wrap the rice. When the front end of the leaf-rolling rod 4061 moves away from the second support plate 407, the leaf-rolling rod 4061 is pulled out from the wrapped rice.

[0034] As attached Figure 1-2 and attached Figure 7-12 As shown, the second angle leaf-rolling mechanism 408 includes a third motor 4081, a third gear 4082, a swing frame 4083, and a swing rod 4084. The third gear 4082 rotates within the rotating frame 405 via a rotating shaft. There are two third gears 4082, and their teeth mesh with each other. Both third gears 4082 are coaxially fixedly connected to the swing frame 4083. The front end of the swing frame 4083 is located below the second support plate 407. The front end of the swing frame 4083 is fixedly connected to the swing rod 4084. The swing rod 4084 is in a vertical state, and its top end is at the same height as the second support plate 407. After the swing rod 4084 rotates to a horizontal position, it is located above the second support plate 407. The third motor 4081 is fixedly connected to the side of the rotating frame 405. The input end of the third motor 4081 is electrically connected to the output end of the controller 5. The output end of the third motor 4081 is fixedly connected to the rotation center of one of the third gears 4082. The second angle leaf-rolling mechanism 408 works as follows: the controller 5 controls the third motor 4081 to be powered on, the third motor 4081 drives the third gear 4082 connected to it to rotate, the third gear 4082 drives another third gear 4082 to rotate synchronously in the opposite direction through inter-tooth meshing, the two third gears 4082 respectively drive the swing frame 4083 fixed to it on the same axis to swing, the swing frame 4083 drives the swing rod 4084 at its front end to rotate from the vertical state to the horizontal state, so that the top of the swing rod 4084 rotates from the position flush with the second support plate 407 to above the second support plate 407. When the swing rod 4084 is in the vertical state, it supports the two sides of the grape leaf. When the swing rod 4084 rotates to the horizontal state, it flips the two sides of the grape leaf towards the middle.

[0035] The working principle of this device is as follows: Grape leaves are placed into the water channel of the water tank conveyor 1. The water tank conveyor 1 uses water flow to send the grape leaves to the leaf picking channel. Then, the conveying mechanism 2 picks up the grape leaves and conveys them upward. At this time, the first support plate 3012 of the first transfer mechanism 3 receives the grape leaves. Then, the first transfer mechanism 3 drives the first support plate 3012 to rotate until the first support plate 3012 moves diagonally downward from above the second support plate 407 of the leaf roller 4 to below the second support plate 407. At this time, the grape leaves fall onto the second support plate 407, completing the transfer. Then, the leaf roller 4 rolls the grape leaves to wrap them. After the wrapping is completed, the first support plate 3012 of the second transfer mechanism 3 moves diagonally upward from below the second support plate 407 of the leaf roller 4 to above the second support plate 407 to lift the wrapped product. The second transfer mechanism 3 turns the wrapped product to facilitate workers to take it out, completing the process.
