Description

Technical Field

[0001] This invention relates to a low-sugar seaweed roll forming machine, belonging to the field of seaweed roll production and processing technology. Background Technology

[0002] Seaweed rolls on the market are currently more popular with consumers due to their unique taste.

[0003] Nori rolls are a type of food made from seaweed that has been baked and seasoned. The production process of nori rolls mainly includes baking, seasoning, and rolling. There are two types of joint bonding in the rolling process: one is to add seasoning powder or seasoning syrup to the joint, which is called low-sugar nori roll in this invention; the other is to add sugar powder or seasoning syrup to the entire surface of the seaweed sheet, which is called full-sugar nori roll.

[0004] Currently, most low-sugar seaweed rolls on the market are processed manually, which results in low processing efficiency, difficulty in guaranteeing quality, and relatively high production costs. In addition, manual operation cannot guarantee food hygiene and poses safety hazards. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, the present invention provides an automatic forming machine for low-sugar seaweed rolls, thereby improving the processing efficiency of seaweed rolls.

[0006] To achieve the above objectives, the technical solution proposed by this invention is as follows: a low-sugar seaweed roll forming machine, comprising a frame, wherein the frame is provided with a first station, a second station, a third station, a fourth station, and a fifth station from left to right; the first station is provided with a storage device and a dispensing device, the dispensing device being used to take the seaweed out of the storage device and place it at the second station; the second, third, and fourth stations are provided with feeding devices, used to sequentially feed the seaweed at the second station to the next station up to the fifth station; the feeding device is provided with a powder adding device corresponding to the second station, which moves with the feeding device, for adding sugar powder to the seaweed; the third station is provided with a cutting device, used to cut the seaweed; the fourth station is provided with a heating device, used to heat the seaweed; and the fifth station is provided with a baking, rolling, and unrolling device, used to bake, roll, and unroll the seaweed.

[0007] A further design of the above technical solution is as follows: the grilling and unrolling device includes a grilling mechanism, a rolling mechanism and an unrolling mechanism, wherein the grilling mechanism includes a main heating plate disposed at station V and a heating tube disposed within the main heating plate;

[0008] The vegetable rolling mechanism includes a screw and nut sub-module mounted on the frame, a vegetable rolling and unloading fixing plate that moves left and right under the drive of the screw and nut sub-module, a vegetable rolling lifting cylinder mounted on the vegetable rolling and unloading fixing plate, a vegetable rolling motion box that moves up and down under the drive of the vegetable rolling lifting cylinder, a winding roller rotatably connected to the vegetable rolling motion box, and a rack mounted on the frame. The winding roller includes a roller body portion located outside the vegetable rolling motion box and a gear tooth portion located inside the vegetable rolling motion box. The vegetable rolling lifting cylinder drives the winding roller to move downward, the roller body portion abuts against the seaweed on the main heating plate, and the gear tooth portion meshes with the rack. The screw and nut sub-module drives the winding roller to move left and right, and the winding roller rotates under the action of the rack, rolling the seaweed on the main heating plate onto the roller body portion to form a seaweed roll.

[0009] The unwinding mechanism includes an unwinding rodless cylinder mounted on the rolling motion box, an unwinding lifting cylinder that moves back and forth under the action of the unwinding rodless cylinder, a finger cylinder that moves up and down under the action of the unwinding lifting cylinder, and a food clamp connected to the finger cylinder. The unwinding lifting cylinder moves the food clamp to the same height as the winding roller. The unwinding rodless cylinder moves the food clamp backward toward the winding roller, so that the seaweed roll is in the middle of the food clamp. The finger cylinder moves the food clamp to perform a clamping action, and the food clamp clamps the seaweed roll. The unwinding rodless cylinder moves the food clamp forward away from the winding roller, and the food clamp pulls the seaweed roll away from the winding roller, completing the unwinding.

[0010] The winding roller is hollow, and the roller body has several air holes on the side that is in contact with the seaweed. The end of the winding roller near the rolling box is connected to a vacuum system.

[0011] The vegetable storage device includes a vegetable storage cylinder and a vegetable lifting mechanism. The vegetable lifting mechanism includes a vegetable lifting motor, a vegetable lifting screw connected to the output shaft of the vegetable lifting motor, a vegetable lifting nut cooperating with the vegetable lifting screw, a vegetable lifting support plate fixed on the vegetable lifting nut with one end extending into the vegetable storage cylinder, and a vegetable lifting guide rod arranged inside the vegetable storage cylinder parallel to the vegetable lifting screw. The seaweed is placed on the vegetable lifting support plate. The vegetable lifting motor drives the vegetable lifting screw to rotate, the vegetable lifting nut moves upward along the vegetable lifting screw, and drives the vegetable lifting support plate to move upward along the vegetable lifting guide rod, pushing the seaweed upward out of the vegetable storage cylinder.

[0012] The vegetable feeding device includes a vegetable suction mechanism and a spiral rotation mechanism. The spiral rotation mechanism includes a vegetable suction lifting guide rod mounted on the frame and threaded at its lower part; a vegetable suction rotation limiting guide rod mounted on the frame and parallel to the vegetable suction lifting guide rod; a vegetable suction lifting nut threaded to the vegetable suction lifting guide rod; a sliding sleeve fitted on the upper part of the vegetable suction lifting guide rod and slidably connected to it; a friction block fitted on the sliding sleeve and fixedly connected to the vegetable suction lifting nut; a rotating rod fitted on the upper part of the vegetable suction lifting guide rod and fixed to the sliding sleeve; and limiting short rods and limiting rods on both sides of the rotating rod. The system comprises a long rod, a driven gear fixed on the vegetable suction lifting nut, a rotation limiting guide sleeve sleeved on and slidably connected to the vegetable suction rotation limiting guide rod, a rotation follower base plate fixed on the rotation limiting guide sleeve, a vegetable suction rotation motor fixed on the rotation follower base plate, and a driving gear connected to the output end of the vegetable suction rotation motor and meshing with the driven gear. The vegetable suction lifting nut is rotatably connected to the rotation follower base plate. The vegetable suction mechanism includes a vacuum suction cup disposed at one end of the rotating rod and a counterweight disposed at the other end of the rotating rod, with the vacuum suction cup and the counterweight arranged on both sides of the vegetable suction lifting guide rod.

[0013] The vacuum suction cup picks up seaweed from the top plate. At this time, the short and long limit rods are positioned on both sides of the rotating rod. The suction scrolling motor drives the suction lifting nut to rotate through the drive and driven gears. The suction lifting nut moves upward along the suction lifting guide rod, causing the scrolling follower base plate and the scrolling limiting guide sleeve to move upward along the suction scrolling limiting guide rod. This also causes the friction block to rotate and move upward. The sliding sleeve and the rotating rod move upward under the restriction of the short and long limit rods. When the rotating rod passes the short limit rod, the friction between the friction block and the sliding sleeve is greater than the friction between the sliding sleeve and the suction lifting guide rod. The friction block rotates, causing the sliding sleeve and the rotating rod to rotate along the suction lifting guide rod. When the vacuum suction cup rotates to the second position, the seaweed is put down. The suction scrolling motor rotates in the opposite direction, causing the sliding sleeve to rotate in the opposite direction and move downward. This causes the rotating rod to rotate in the opposite direction and move downward. When the rotating rod rotates to abut against the long limit rod, it moves downward under the restriction of the long limit rod to achieve a reset.

[0014] The food delivery device includes a pusher cylinder mounted on the frame, a first pressing and lifting cylinder that moves left and right under the drive of the pusher cylinder, a pusher vertical plate that moves up and down under the drive of the first pressing and lifting cylinder, a pressing slide bar and a pressing cross bar fixed on the pusher vertical plate, a plurality of pressing conveying rods arranged along the length of the pressing cross bar, a second pressing and lifting cylinder mounted on the frame, and a pressing slide seat that moves up and down under the drive of the second pressing and lifting cylinder and is slidably connected to the pressing slide bar.

[0015] The first and second pressing cylinders drive the pressing conveyor rod to move downwards and press the seaweed down. The pusher cylinder drives the pressing conveyor rod to move left and right through the pusher plate, sending the seaweed to the next work station.

[0016] The powdering device includes a vibrating screen mounted on a pressing bar. The pressing bar moves up and down, and the sugar powder in the vibrating screen falls onto the seaweed.

[0017] The slicing device includes a cutting strut mounted on the frame, a cutting rodless cylinder mounted on the cutting strut, a cutting lifting cylinder that moves back and forth under the drive of the cutting rodless cylinder, and a slicing blade that moves up and down under the drive of the cutting lifting cylinder.

[0018] The cutting cylinder lifts the cutting blade downwards, and the cutting blade presses against the seaweed. The cutting rodless cylinder, through the cutting cylinder lifts the cutting blade, moves it back and forth to cut the seaweed.

[0019] The heating device includes a heating lifting cylinder mounted on the frame and a front heating plate that moves up and down under the action of the heating lifting cylinder; the heating lifting cylinder moves the front heating plate downward, and the front heating plate approaches the seaweed to heat the seaweed.

[0020] The frame also has a VI station to the right of station V. A seaweed roll unwinding and conveying mechanism is provided at station VI. A seaweed roll packing and moving mechanism is provided below the end of the seaweed roll unwinding and conveying mechanism away from the baking roll unwinding device. A seaweed roll box is provided on the seaweed roll packing and moving mechanism. The lead screw nut sub-module drives the unwinding mechanism to move to the right to station VI. The finger cylinder drives the vegetable clamp to put down the seaweed roll. The seaweed roll falls onto the seaweed roll unwinding and conveying mechanism and falls into the seaweed roll box under the action of the seaweed roll unwinding and conveying mechanism.

[0021] The beneficial effects of this invention are as follows:

[0022] This invention achieves rapid lifting and lowering of seaweed sheets within the storage cylinder through a storage device, and continuous automatic feeding of seaweed sheets through a feeding device. Its ingenious structure and compact layout significantly improve production efficiency. A conveying device enables the transport of seaweed sheets between workstations, achieving rapid circulation and precise positioning, ensuring accurate operation of the seaweed sheets in subsequent processes. A powder-adding device enables precise addition of seaweed sheets, avoiding the hygiene and safety hazards associated with manual sugar addition. A cutting device enables rapid cutting of seaweed sheets, improving the efficiency of subsequent seaweed roll processing. A heating device provides pre-heating treatment of the sugar powder, preventing spillage during movement and providing favorable conditions for the subsequent conversion of the sugar powder into syrup. A baking, rolling, and unrolling device enables continuous, precise, and automatic operation of baking, rolling, and unrolling the seaweed sheets.

[0023] The fully automatic seaweed roll forming machine designed in this invention can effectively improve the processing efficiency of seaweed rolls, reduce costs, ensure the product quality of seaweed rolls, and improve hygiene and safety issues. Attached Figure Description

[0036] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Example 1

[0037] like Figure 1 , Figure 2 , Figure 3 As shown, the low-sugar seaweed roll forming machine of this embodiment adopts a six-station process to achieve the rolling of low-sugar seaweed rolls. Specifically, it includes a frame 19, which is provided with stations I, II, III, IV, V, and VI from left to right. Station I is provided with a storage device 1 and a dispensing device 4. The dispensing device 4 is used to take the seaweed sheets (nori) from the storage cylinder 1 and place them at station II. Stations II, III, and IV are provided with a feeding device 9. The feeding device 9 spans stations II, III, and IV and can move one station distance to the right and then return to its original position, thereby feeding the seaweed sheets at station II to the next station up to station V. The feeding device 9 corresponds to... Station II is equipped with a powder-adding device 5 that moves with the food delivery device 9 to add powdered sugar to the seaweed sheets; Station III is equipped with a cutting device to cut the seaweed sheets; Station IV is equipped with a heating device 18 to heat the seaweed sheets; Station V is equipped with a baking and unrolling device to bake, roll, and unroll the seaweed sheets to make seaweed rolls; Station VI is equipped with a seaweed roll unrolling conveyor 14 and a seaweed roll boxing mechanism 16. The seaweed roll boxing mechanism 16 is equipped with a seaweed roll box 15. The seaweed roll unrolling conveyor 14 is used to transport the unrolled seaweed rolls into the seaweed roll box 15, and the seaweed roll boxing mechanism 16 is used to transport the seaweed roll box 15 to the packaging area for further packaging.

[0038] This embodiment achieves automated production of seaweed rolls through the coordination of devices at each workstation, thereby improving production efficiency. Example 2

[0039] This embodiment is a further design based on Embodiment 1, such as... Figure 1 , Figure 2 and Figure 4As shown, the vegetable storage device 1 in this embodiment includes a vegetable storage cylinder 201 fixed on a frame and open at the top, and a vegetable-lifting mechanism 2. The vegetable storage cylinder 201 has an elongated hole on one side, arranged vertically. The vegetable-lifting mechanism 2 includes a vegetable-lifting motor 407 fixed on the frame, a vegetable-lifting screw 404 connected to the output shaft of the vegetable-lifting motor 407, a vegetable-lifting nut 406 cooperating with the vegetable-lifting screw 404, a vegetable-lifting support plate 405 fixed to the vegetable-lifting nut 406 and with one end extending into the vegetable storage cylinder 201 through the elongated hole, and a... The top-loading guide rod 401, which is placed inside the vegetable storage cylinder 201 and is parallel to the top-loading screw 404, slides with the top-loading tray 405 to guide the up-and-down movement of the top-loading tray 405. The end of the top-loading screw 404 away from the top-loading motor 407 is rotatably connected to the top-loading mechanism upper fixing plate 403 through the top-loading rod support seat 608. The top-loading mechanism upper fixing plate 403 is fixed to one side of the vegetable storage cylinder 201. The nori sheets are stacked on the top-loading tray 405.

[0040] The vegetable-topping motor 407 drives the vegetable-topping screw 404 to rotate, which in turn drives the vegetable-topping nut 406 to move upward along the vegetable-topping screw 404, and drives the vegetable-topping support plate 405 to move up and down along the vegetable-topping guide rod 401, thereby realizing the lifting and lowering of the seaweed sheets in the vegetable storage cylinder 1, and can push the seaweed sheets upward out of the vegetable storage cylinder 201. Example 3

[0041] This embodiment is a further design based on Embodiment 2, such as... Figure 1 , Figure 2 and Figure 5As shown, the vegetable feeding device 4 in this embodiment includes a vegetable suction mechanism and a spiral shifting mechanism. The spiral shifting mechanism includes a spiral shifting mechanism pad 501 mounted on the frame 19, a vegetable suction rod support 502 and a lifting screw support 504 fixed on the spiral shifting mechanism pad 501, a vegetable suction lifting guide rod 507 mounted on the lifting screw support 504 and having threads at its lower part, and a vegetable suction shifting mechanism mounted on the vegetable suction rod support 502 and parallel to the vegetable suction lifting guide rod 507. The following components are included: a limiting guide rod 503, a suction lifting nut 510 threaded to the suction lifting guide rod 507, a sliding sleeve 509 fitted onto the upper part of the suction lifting guide rod 507 and slidably connected to it, a silicone elastic friction block 508 fitted onto the sliding sleeve 509 and fixedly connected to the suction lifting nut 510, a rotating rod 205 fitted onto the upper part of the suction lifting guide rod 507 and fixed onto the sliding sleeve 509, and limiting short rods 206 on both sides of the rotating rod 205. The structure includes a long rod 207, a driven gear 511 fixed on the suction lifting nut 510, a rotation limiting guide sleeve 505 sleeved on and slidably connected to the suction rotation limiting guide rod 503, a rotation follower base plate 512 fixed on the rotation limiting guide sleeve 505, a suction rotation motor 504 fixed on the rotation follower base plate 512, and a driving gear 506 connected to the output end of the suction rotation motor 504 and meshing with the driven gear. The suction lifting nut 510... The nut sleeve 513 is rotatably connected to the rotating follower base plate 512; the vegetable suction mechanism includes a vacuum suction cup 3 set at one end of the rotating rod 205 and a counterweight block 208 set at the other end of the rotating rod 205. The vacuum suction cup 3 and the counterweight block 208 are arranged on both sides of the vegetable suction lifting guide rod 507. The vacuum suction cup 3 includes a vegetable suction chamber plate 203 and a vegetable suction plate 202. The vegetable suction plate 202 is provided with several air holes. The vegetable suction chamber plate 203 is connected to an air pipe quick connector 402 through a vegetable suction welding pipe 204.

[0042] The initial position of the rotating rod 205 is with the vacuum suction cup 3 above the top vegetable tray 405. At this time, the limiting short rod 206 and the limiting long rod 207 are positioned on both sides of the rotating rod 205. After the vacuum suction cup 3 picks up a piece of seaweed, the suction rotation motor 504 drives the suction lifting nut 510 to rotate through the drive gear and driven gear, and causes the suction lifting nut 510 to move upward along the suction lifting guide rod 507. This causes the rotation follower base plate 512, the suction rotation motor 504, and the rotation limiting guide sleeve 505 to move upward along the suction rotation limiting guide rod 503, and also causes the friction block 508 to rotate and move upward. The upper part of the sliding sleeve 509 is provided with a convex ring, and the upper end of the friction block 508 abuts against the convex ring. The upward movement of the friction block 508 pushes the sliding sleeve 509 and the rotating rod 205 along the suction lifting guide rod 507 under the restriction of the limiting short rod 206 and the limiting long rod 207. As the rotating rod 205 moves upward, when it passes the limiting short rod 206, the friction between the friction block 508 and the sliding sleeve 509 is greater than the friction between the sliding sleeve 509 and the suction lifting guide rod 507. Therefore, the rotation of the friction block 508 can drive the sliding sleeve 509 and the rotating rod 205 to rotate along the suction lifting guide rod 507. After the vacuum suction cup 3 rotates 180° to the second working position, the seaweed sheet is placed down. The suction indexing motor 504 rotates in the opposite direction, driving the sliding sleeve 509 to rotate in the opposite direction and move downward under the action of the vacuum suction cup 3 and the counterweight block 208. This drives the rotating rod 205 to rotate in the opposite direction and move downward. When the rotating rod 205 rotates 180° and comes into contact with the limiting long rod 207, the rotating rod 205 cannot continue to rotate under the restriction of the limiting long rod 207 and can only move downward to reset. The above operation is repeated to pick up the next seaweed sheet.

[0043] In this embodiment, a counterweight block 208 is used to balance the weight of the vacuum suction cup 3, and the friction between the friction block 508 and the sliding sleeve 509 is increased by increasing the weight of the rotating rod 205, so as to ensure the smooth rotation of the suction cup. The limiting short rod 206 and the long suction limiting long rod 207 further ensure the accuracy of the extreme position of the vacuum suction cup 3 and control the rotation timing of the rotating rod 205. Example 4

[0044] This embodiment is a further design based on Embodiment 3, such as... Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 8As shown, there are continuous food delivery panels 6 on stations II, III and IV. The food delivery panels 6 are fixed to the frame by food delivery panel pads 221. The seaweed sheets are placed on the food delivery panels 6 and move to the next station in sequence under the action of the food delivery device 9. The food delivery device 9 has a symmetrical structure, including a pneumatic conveying mechanism 20 and a food pressing mechanism. The pneumatic conveying mechanism 20 consists of two rodless pusher cylinders 209 mounted on the front and rear sides of the frame 19. The food pressing mechanism includes a first food pressing lifting cylinder 6071 mounted on the slider 801 of the rodless pusher cylinder and moving left and right under the action of the rodless pusher cylinder 209; a pusher vertical plate 802 mounted at the output end of the first food pressing lifting cylinder 6071 and moving up and down under the action of the first food pressing lifting cylinder 6071; and a food pressing slide rod 219 fixed on the pusher vertical plate 802. The two ends of the food pressing slide rod 219 are respectively provided with a left fixing seat 803 and a right fixing seat 805. The left end of the food pressing slide rod 219 is connected to the pusher vertical plate 802 through the left fixing seat 803. Between the left fixed seat 803 and the right fixed seat 805 of the pressing slide rod, there is also a pressing crossbar 313 arranged parallel to the pressing slide rod 219. Several pressing conveying rods 305 are arranged along the length of the pressing crossbar 313. The pressing conveying rods 305 are connected to the lower part of the pressing crossbar 313 through the vegetable buffer rubber pad 804. The pressing conveying rods 305 are arranged at the front and rear. The vegetable feeding device 9 also includes a second pressing lifting cylinder 6072 set on the frame 19 and a pressing slide seat 601 connected to the output end of the second pressing lifting cylinder 6072 through the pressing cylinder connecting plate 602 and moving up and down under the drive of the second pressing lifting cylinder 6072. The pressing slide seat 601 is sleeved on the pressing slide rod 219 and is slidably connected to the pressing slide rod 219 through the pressing guide sleeve 605. The second pressing and lifting cylinder 6072 is fixed to the frame 19 via the pressing and lifting cylinder fixing base plate 218 and the pressing and lifting cylinder fixing angle steel 220.

[0045] The first pressing and lifting cylinder 6071 and the second pressing and lifting cylinder 6072 drive the pressing and conveying rod 305 downward to press the seaweed sheets against the feeding panel 6. The pusher cylinder 209 drives the pressing and conveying rod 305 to move left and right through the pusher plate 802. The pressing slide rod 219 and the pressing slide seat 601 cooperate to guide the left and right movement of the pressing and conveying rod 305. The pusher cylinder 209 moves for one workstation length, driving the pressing and conveying rod 305 to continuously, automatically and accurately convey the seaweed sheets to the next workstation. After the seaweed sheets are delivered to the next workstation, the first pressing and lifting cylinder 6071 and the second pressing and lifting cylinder 6072 drive the pressing and conveying rod 305 upward, and the pusher cylinder 209 drives the pressing and conveying rod 305 to move to the left to return to its original position.

[0046] In this embodiment, the bottom surface of the pressing conveyor rod 305 is provided with multiple V-shaped grooves to increase the friction when in contact with the seaweed sheet.

[0047] like Figure 9 As shown, in this embodiment, the powder adding device 5 is positioned at the far left of the food delivery device 9. When the food delivery device 9 is in positions II to IV, the powder adding device 5 is located at position II. At this time, the vacuum suction cup 3 of the food placement device 4 is located at position I. When the vacuum suction cup 3 rotates to position II, the food delivery device 9 moves to the right, so that the powder adding device 5 is located at position III. At this time, the seaweed sheet can fall onto the food delivery panel 6.

[0048] The powder adding device 5 includes a vibrating screen 901, which has two material dividing angles 902 and a screen 903 at the bottom. The two material dividing angles 902 have a certain inclination angle and two drop-out openings in the vibrating screen 901, which serve to block the powdered sugar, so that the powdered sugar can only fall from the two drop-out openings, thus controlling the position of the powdered sugar falling on the seaweed sheet. When the first pressing and lifting cylinder 6071 and the second pressing and lifting cylinder 6072 move up and down, the powdered sugar can be evenly shaken from the screen 903 onto the adhesive part of the rolled seaweed. The material dividing angles block the powdered sugar, preventing the powdered sugar from falling onto other parts of the seaweed sheet. Example 5

[0049] This embodiment is a further design based on Embodiment 4, such as... Figure 6 As shown, the slicing device in this embodiment includes a cutting strut 210 mounted on the frame 19. The cutting strut 210 spans back and forth across the third work station. A cutting motion mechanism 8 is mounted on the cutting strut 210. The cutting motion mechanism 8 includes a cutting rodless cylinder 301 fixedly connected to the cutting strut 210 via a cutting cylinder connecting plate 302, a cutting lifting cylinder 603 that moves back and forth under the drive of the cutting rodless cylinder 301, and a slicing blade assembly 7 that moves up and down under the drive of the cutting lifting cylinder 603. The slicing blade assembly 7 includes a slicing blade seat 604 and a slicing blade 606.

[0050] The cutting lifting cylinder 603 drives the slitting blade 606 to move downwards, and the slitting blade 606 presses against the seaweed sheet. The cutting rodless cylinder 301 drives the slitting blade 606 to move back and forth through the cutting lifting cylinder 603 to cut the seaweed sheet. Example 6

[0052] This embodiment is a further design based on Embodiment 5, combined with... Figure 1 and Figure 7 As shown, the roasting and unrolling device of this embodiment includes a roasting mechanism, a rolling mechanism and an unrolling mechanism. The roasting mechanism includes a main heating plate 13 fixed to the V position of the frame by a side fixing angle steel 705 and connected to the vegetable feeding panel 6 on the same plane, and a heating tube disposed in the main heating plate 13. The main heating plate 13 roasts the seaweed sheets into nori sheets, and at the same time melts the sugar powder on them into the nori sheets.

[0053] The vegetable rolling mechanism includes a vegetable rolling assembly 12 and a vegetable rolling motion mechanism 17. The vegetable rolling motion mechanism 17 includes a screw and nut sub-module 217 mounted on the frame, a vegetable rolling and unloading fixing plate 215 that moves left and right under the drive of the screw and nut sub-module 217, two vegetable rolling lifting cylinders 212 mounted on both sides of the vegetable rolling and unloading fixing plate 215, a vegetable rolling motion box 214 that moves up and down under the drive of the vegetable rolling lifting cylinder 212 on one side, and a rack 216 mounted on the frame 19. The vegetable rolling assembly 12 includes two left and right winding rollers 311 rotatably connected to the vegetable rolling motion box 214. The winding rollers 311 are hollow shaft structures, including those located on the roll... The rolling mechanism includes a roller body outside the rolling mechanism housing 214 and a gear tooth part 3111 inside the rolling mechanism housing 214. The upper part of the rolling mechanism housing 214 is provided with a rolling mechanism housing cover 213 for easy maintenance and replacement of the winding roller 311. The lower part is provided with a rolling mechanism housing bottom plate 704 for supporting the rack 216. The rack 216 is fixed to the rolling mechanism housing bottom plate 704 by the rack pad 314. A pair of deep groove ball bearings 703 are installed at both ends of the gear tooth part and installed in the winding roller bearing seat 213. The winding roller bearing seat 213 is installed in the rolling mechanism housing 214 to support the rolling movement of the winding roller 311.

[0054] The two lifting cylinders 212 move synchronously, driving the winding roller 311 to move downward. The roller body abuts against the sugar-free side of the seaweed on the main heating plate 13, and the toothed part 3111 meshes with the rack 216. The lead screw nut sub-module 217 drives the winding roller 311 to move left and right. The winding roller 311 rotates under the action of the rack 216, winding the seaweed on the main heating plate 13 onto the roller body to form a seaweed roll.

[0055] In this embodiment, the winding roller 311 is hollow, and the roller body has several air holes on the side that is in contact with the seaweed. The end of the winding roller 311 near the rolling movement box 214 is connected to a vacuum system. The air holes on the winding roller 311 are on the side of the seaweed sheet without sugar powder directly below the rolling position. When the vacuum system is turned on, the seaweed sheet is adsorbed and adhered to the winding roller 311. The winding roller 311 is driven to move towards the side of the seaweed sheet with sugar powder through the screw nut sub-module 217, so that the seaweed sheet is glued into a roll.

[0056] The unwinding mechanism includes a vegetable unwinding component 10 and a vegetable unwinding motion mechanism 11. The vegetable unwinding motion mechanism 11 includes a rodless unwinding cylinder 310 mounted on two side vegetable-rolling lifting cylinders 212 and movable up and down by the vegetable-rolling lifting cylinders 212; a unwinding lifting cylinder 306 movable back and forth by the unwinding lifting cylinder 310; and a finger cylinder 309 movable up and down by the unwinding lifting cylinder 306. The vegetable unwinding component 10 includes a vegetable clamp 308 connected to the finger cylinder 309. The unwinding lifting cylinder 306 is mounted via the finger cylinder. The side plate 701 and the unwinding cylinder connecting plate 307 are connected to the unwinding rodless cylinder 310. The finger cylinder connecting plate 702 is located at the output end of the unwinding lifting cylinder 306 and can move up and down with the unwinding lifting cylinder 306. The finger cylinder connecting plate 702 is U-shaped and spans across the unwinding rodless cylinder 310. The finger cylinder connecting plate 702 is located on both sides of the unwinding rodless cylinder 310 and is connected to a finger cylinder 309. The finger cylinder 309 controls a set of food clamps 308, and a set of food clamps 308 corresponds to a winding roller 311.

[0057] Two vegetable roll lifting cylinders 212 lift and lower synchronously, driving the unwinding rodless cylinder 310 and the winding roller 311 to lift and lower. During vegetable rolling, the unwinding lifting cylinder 306 moves the vegetable clamp 308 upwards, positioning it higher than the winding roller 311 to prevent collision with the frame 19. Then, the unwinding rodless cylinder 310 and the winding roller 311 descend. The winding roller 311, driven by the lead screw nut sub-module 217, completes the vegetable rolling process, followed by unwinding. The two vegetable roll lifting cylinders 212 drive the unwinding rodless cylinder 310 and the winding roller 311 to lift and lower. As the winding roller 311 rises, the unwinding lifting cylinder 306 moves the food clamp 308 downwards to the same height as the winding roller 311. The unwinding rodless cylinder 306 then moves the food clamp 308 backwards towards the winding roller 311, positioning the seaweed roll in the middle of the food clamp 308. The finger cylinder 309 then moves the food clamp 308 to perform a clamping action, holding the seaweed roll. The unwinding rodless cylinder 310 then moves the food clamp 308 forwards away from the winding roller 311, causing the seaweed roll to detach from the winding roller 311, completing the unwinding process. In this embodiment, a silicone plate is adhered inside the food clamp 308. Multiple small grooves are engraved on the surface of the silicone plate, increasing the friction between the food clamp and the seaweed roll, allowing the seaweed roll to unwind smoothly.

[0058] In this embodiment, the seaweed roll conveying mechanism 14 is installed on the right side of the unrolling mechanism. The seaweed roll conveying mechanism 14 is located below the end away from the baking and unrolling device. The seaweed roll packing mechanism 16 is a conveyor belt structure. The seaweed roll packing mechanism 16 has a seaweed roll box 15 on it.

[0059] The lead screw and nut sub-module 217 drives the unwinding mechanism to move to the right to the VI station. The finger cylinder 309 drives the vegetable clamp 308 to put down the seaweed roll. The seaweed roll falls onto the seaweed roll unwinding conveyor 14 and falls into the seaweed roll box 15 under the action of the seaweed roll unwinding conveyor 14. The running speed of the seaweed roll boxing motion mechanism 16 is controlled so that the seaweed rolls are neatly stacked in the seaweed roll box 15. After the seaweed roll box 15 is full, it is transported by the seaweed roll boxing motion mechanism 16 to the packaging area for further packaging.

[0060] The fully automatic seaweed roll forming machines described in the above embodiments effectively improve the processing efficiency of seaweed rolls and reduce costs.

[0061] The above description is merely a specific embodiment of the present invention, but the scope of protection of the invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art or related fields within the technical scope disclosed in the present invention are covered within the technical protection scope of the present invention.
