Description

Technical Field

[0001] This invention relates to the field of seaweed production technology, specifically to an automatic feeding device and a feeding method for seaweed production. Background Technology

[0002] Nori is a food made from laver as raw material, through processes such as washing, crushing, seasoning, shaping, and baking. During the production of nori, the surface of the nori is coated with oil. However, the surface of the nori is not well coated with oil during the production and conveying process. When using it, oil can only be applied to one side of the nori, while the other side of the nori is in contact with the surface of the conveyor belt. Oil can be applied to both sides of the nori at the same time. At the same time, when the conveyor belt is transporting the nori, a certain amount of nori residue will remain on the surface of the conveyor belt. It is not possible to clean the residue on the surface of the conveyor belt in real time.

[0003] Chinese patent CN219807364U discloses an automatic feeding and conveying device for seaweed production, including a transmission belt. Limit plates are installed on both sides of the transmission belt, and a collection box is installed at the bottom of the limit plates. A through hole is opened at the top of the collection box, and a partition is installed at the bottom inner part of the collection box. Several slots are opened at the top of the partition. An installation shaft is rotatably mounted on the inner wall of the collection box, located on the side of the partition. Several brushes are installed on the outer wall of the installation shaft. This invention allows the collection box to store oil while simultaneously allowing oil to be applied to the surface of the transmission belt via the brushes. The brushes can also clean residue from the transmission belt surface. The collection box can clean excess oil from the brushes and collect residue from the transmission belt surface.

[0004] However, the above technical solution still has certain drawbacks in use. For example, although it can clean debris and excess oil from the conveyor belt surface with a brush, it does not have a structure for cleaning the brush, the slot, and the collection box. As a result, the oil and seaweed debris cleaned by the brush will remain in the collection box. Over time, the mixture of these debris and oil will breed bacteria. When the brush comes into contact with the slot again, these bacteria will adhere to the brush, which will not only fail to clean the conveyor belt but also contaminate the surface of the conveyor belt. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic feeding device for food production and a feeding method for seaweed production, thus solving the aforementioned problems.

[0013] Preferably, the cleaning component includes an upper pipe and a lower pipe, both of which are fixedly connected to the fixed frame. The upper pipe is positioned above the lower pipe, and the upper pipe is provided with several angled nozzles. The lower pipe is provided with several arrayed inclined nozzles. After the angled nozzles and inclined nozzles move down, they can blow air to clean the surfaces of the upper and lower scrapers. A three-way pipe is fixedly connected to the end of the lower pipe away from the inclined nozzles. The end of the three-way pipe away from the lower pipe is connected to the upper pipe, and a high-temperature steam pipe is connected to the outside of the three-way pipe.

[0014] Preferably, the fixed motor is fixedly connected to the processing box, a drive wheel is fixedly connected to the output shaft of the fixed motor, a driven wheel is drivenly connected to the inner side of the drive wheel, the driven wheel is fixedly connected to one end of the sponge oiling roller, a linkage wheel is also fixedly connected to the sponge oiling roller, a drive wheel is drivenly connected to the outer side of the linkage wheel, and the drive wheel is fixedly connected to the reciprocating lead screw.

[0015] Preferably, the oil supply structure includes a rotary joint and circumferentially distributed oil outlet holes. The rotary joint is located at one end of the sponge oiling roller, and a connecting pipe is installed at the end of the rotary joint away from the sponge oiling roller. The connecting pipe is connected to the atomizing spray pipe, which is installed on the conveying frame. The array of oil outlet holes is formed on the sponge oiling roller, and a sponge sleeve is provided on the outer side of the sponge oiling roller.

[0016] Preferably, the filter screen is also provided with a discharge port, which is located below the cleaning component.

Protective shells are provided on the outer sides of the main pulley and the auxiliary pulley, and the protective shells are installed on the conveyor frame.

[0018] A feeding method for seaweed production, using the aforementioned automatic feeding equipment, includes the following steps:

[0019] S1. The conveyor belt is driven by a drive mechanism;

[0020] S2. Oil is supplied to the atomizing nozzle and the sponge oiling roller through the oil supply structure;

[0021] S3. Place the seaweed sheet on the conveyor belt, and then automatically transport and feed the seaweed sheet through the conveyor belt. The seaweed sheet is then coated with oil on both sides through the atomizing spray nozzle and the sponge oiling roller.

[0022] Compared with the prior art, the present invention provides an automatic feeding device for food production and a feeding method for seaweed production, which has the following beneficial effects:

[0023] 1. In this invention, during oiling, oil is sprayed onto the upper surface of the seaweed sheet through an atomizing nozzle, and a fixed motor drives a sponge oiling roller to rotate, thereby oiling the surface of the conveyor belt and achieving oiling of both sides of the seaweed sheet. As the sponge oiling roller rotates, an upper scraper and a lower scraper move. The upper scraper scrapes the surface of the sponge oiling roller, removing excess oil and seaweed debris adhering to its surface. The scraped oil and seaweed debris fall onto a filter screen, where the oil enters the bottom of the processing box, while the seaweed debris remains on the filter screen. The lower scraper then moves to scrape the surface of the filter screen, cleaning up any remaining seaweed debris. As the sponge oiling roller continues to rotate, the upper and lower scrapers reciprocate, achieving the goal of applying oil to the seaweed sheets while removing seaweed debris and excess oil adhering to the sponge oiling roller. The removed oil is then filtered through the filter screen and reused, while the seaweed debris that falls onto the filter screen is removed by the lower scraper. This prevents oil and seaweed debris from accumulating in the processing box, which could lead to bacterial growth and contamination of the conveyor belt over time.

[0024] 2. In this invention, when the upper and lower scrapers move to the position of the pusher, the upper scraper contacts the pusher. At this time, the pusher operates, thereby pushing out the cleaning component. After the cleaning component is pushed out, it cleans the surfaces of the upper and lower scrapers, thereby cleaning the seaweed debris adhering to the upper and lower scrapers. This avoids the problem of seaweed debris accumulating on the upper and lower scrapers, which would cause secondary pollution to the sponge oiling roller.

[0025] 3. In this invention, after the reciprocating screw drives the lower scraper to move, the lower scraper contacts the rack near the cleaning part. At this time, the rack drives the worm wheel and worm on the lower scraper to rotate, causing the lower scraper to flip. Then, as the reciprocating screw rotates again, the lower scraper is brought back to its original position in a flipped state. After that, the reciprocating screw drives the lower scraper to move towards the cleaning part again. When the reciprocating screw drives the lower scraper to move towards the cleaning part again, the rack away from the cleaning part drives the worm wheel and worm to rotate again, causing the lower scraper to flip back to a vertical state, thereby scraping the filter screen surface. This achieves unidirectional scraping of the lower scraper and further avoids the accumulation of seaweed debris on the filter screen. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an automatic feeding device for food production and a feeding method for seaweed production.

[0041] Example 1: Please refer to Figures 1-12 An automatic feeding device for food production includes a conveyor frame 1, on which a conveyor belt 2, a drive mechanism 3 and a processing box 5 are provided. The conveyor belt 2 is used to feed seaweed sheets, and the drive mechanism 3 is used to drive the conveyor belt 2 to rotate.

[0042] The conveyor frame 1 is equipped with an oiling mechanism 4, which includes an atomizing nozzle 41, a sponge oiling roller 42 and an oil supply structure 43. The atomizing nozzle 41, the sponge oiling roller 42 and the oil supply structure 43 are connected. The atomizing nozzle 41 and the sponge oiling roller 42 are used to apply oil to the surface of the seaweed sheet and the surface of the conveyor belt 2, respectively.

[0043] The processing box 5 is equipped with a fixed motor 6, a scraper 7, a pusher 8, a cleaning component 9, and a filter screen 10. The scraper 7 includes an upper scraper 71 and a lower scraper 72. The fixed motor 6 is used to drive the sponge oiling roller 42 and the scraper 7 to operate. The scraper 7 is used to scrape the surface of the sponge oiling roller 42 and the surface of the filter screen 10. The pusher 8 is used to drive the cleaning component 9 to move toward the scraper 7. The cleaning component 9 is used to clean the scraper 7. The filter screen 10 is used to perform solid-liquid separation on the oil-liquid mixture after it is scraped by the upper scraper 71.

[0044] When the sponge oiling roller 42 rotates, the upper scraper 71 can reciprocate along the axial direction of the sponge oiling roller 42 to scrape, and the lower scraper 72 can scrape along the inner bottom surface of the treatment box 5. When the scraping component 7 moves to contact the pushing component 8, the pushing component 8 can drive the cleaning component 9 to move to the upper scraper 71 and the lower scraper 72.

[0045] In use, the drive mechanism 3 drives the conveyor belt 2, which in turn drives the sponge oiling roller 42 via the fixed motor 6. Oil is then supplied to the atomizing nozzle 41 and the sponge oiling roller 42 via the oil supply structure 43. When feeding seaweed sheets, the atomizing nozzle 41 sprays oil onto the upper surface of the seaweed sheets on the conveyor belt 2, and the sponge oiling roller 42 applies oil to the surface of the conveyor belt 2. This allows for subsequent oiling of the other side of the seaweed sheets. The operation of the sponge oiling roller 42 moves the upper scraper 71 and the lower scraper 72. The upper scraper 71 scrapes and squeezes the surface of the sponge oiling roller 42, squeezing out excess oil and cleaning debris adhering to its surface. The mixture of squeezed oil and debris is then filtered through the filter screen 10. After filtration, debris remains on the filter screen 10, while oil enters below the filter screen 10 and remains at the bottom of the processing box 5. When the lower scraper 72 moves, it scrapes the surface of the filter screen 10, thereby cleaning the debris remaining on the filter screen 10. When the upper scraper 71 and the lower scraper 72 move to contact the pusher 8, the pusher 8 drives the cleaning member 9 to move towards the upper scraper 71 and the lower scraper 72. Then, the cleaning member 9 cleans the upper scraper 71 and the lower scraper 72, thereby cleaning the debris adhering to the upper scraper 71 and the lower scraper 72. This achieves the goal of oiling both sides of the seaweed sheet while cleaning excess oil and debris adhering to the surface of the sponge oiling roller 42. It also collects the cleaned debris and cleans the surfaces of the upper scraper 71 and the lower scraper 72, thus avoiding the problem of secondary pollution.

[0046] Example 2: See Figures 1-12Unlike Embodiment 1 described above, the scraping component 7 also includes a reciprocating lead screw 73. Both ends of the reciprocating lead screw 73 are rotatably connected to the processing box 5. A slider 74 is slidably fitted onto the reciprocating lead screw 73. A limit rod 75 is slidably connected to the inner side of the slider 74. Both ends of the limit rod 75 are fixedly connected to the inner side of the processing box 5. A limit hole 76 is formed at one end of the slider 74. A slide rod 77 is slidably connected to the inner side of the limit hole 76. The end of the slide rod 77 away from the limit hole 76 is fixedly connected to the upper scraper 71. The limit holes 76 are distributed on both sides of the slider 74. A limiting spring 78 is fixedly connected, with one end of the limiting spring 78 away from the slider 74 fixedly connected to the upper scraper 71. The limiting springs 78 are distributed on both sides of the slider 74. The scraping component 7 also includes a connecting component 79, which is fixedly connected to the bottom of the slider 74. One end of the connecting component 79 away from the slider 74 is fixedly connected to a bracket 710. The lower scraper 72 is rotatably connected to the inner side of the bracket 710, and both ends of the lower scraper 72 extend out of the bracket 710. A worm gear 711 is rotatably connected to one end of the bracket 710, and a worm 711 meshes with the outer side of the worm gear 711. The worm gear 712 is fixedly connected to one end of the lower scraper 72. A ratchet structure 713 is fixedly connected to the top of the worm 711. A one-way gear 714 is provided on the outside of the ratchet structure 713, and a rack 715 meshes with the outside of the one-way gear 714. The rack 715 is distributed on both sides inside the processing box 5. When the one-way gear 714 moves, it can mesh with the rack 715. A fixed motor 6 is fixedly connected to the processing box 5. A drive wheel 61 is fixedly connected to the output shaft of the fixed motor 6. A driven wheel 62 is driven and connected to the inner side of the drive wheel 61. The driven wheel 62 is fixedly connected to... A linkage wheel 63 is fixedly connected to one end of the sponge oiling roller 42. A drive wheel 64 is connected to the outer side of the linkage wheel 63. The drive wheel 64 is fixedly connected to the reciprocating screw 73. The filter screen 10 is also provided with a discharge port 101, which is located below the cleaning component 9. A collection box 51 is slidably connected to the inside of the treatment box 5, which is located below the discharge port 101. A collection chamber 52 is provided inside the treatment box 5, which is located below the filter screen 10. An oil recovery pipe is also connected to the outside of the collection chamber 52.

[0047] In use, the fixed motor 6 drives the drive wheel 61 to rotate. The rotation of the drive wheel 61 drives the driven wheel 62, the sponge oiling roller 42, the linkage wheel 63, and the drive wheel 64 to rotate. The rotation of the drive wheel 64 drives the reciprocating screw 73 to rotate. The rotation of the reciprocating screw 73 drives the slider 74 to move along the limit rod 75. The movement of the slider 74 drives the upper scraper 71 and the lower scraper 72 to move. When the upper scraper 71 moves, the limit spring 78 squeezes the upper scraper 71, thereby forcing the upper scraper 71 to make close contact with the surface of the sponge oiling roller 42. Afterwards, as the upper scraper 71 moves, it squeezes the surface of the sponge oiling roller 42, thereby squeezing out excess oil. And when the upper scraper 71 moves, it squeezes the surface of the sponge oiling roller 42. 2. The surface debris is scraped away. The oil and debris mixture scraped and squeezed by the upper scraper 71 falls off under the action of gravity. After being filtered by the filter screen 10, the oil falls into the collection chamber 52 and is then discharged through the oil recovery pipe, while the debris remains on the filter screen 10. Then, when the lower scraper 72 moves, it removes the debris remaining on the filter screen 10 and pushes the debris on the filter screen 10 to the discharge port 101. Then, it falls into the collection box 51 through the discharge port 101. Then, the one-way gear 714 on the worm gear 711 contacts the rack 715 at one end of the processing box 5. At this time, as the lower scraper 72 moves, the rack 715 drives the one-way gear 714 to rotate. The rotation of gear 714 drives the ratchet structure 713 to rotate, which in turn drives the worm gear 711 to rotate. The worm gear 711 then drives the worm wheel 712 to rotate, which in turn causes the lower scraper 72 to flip, thus separating the bottom of the lower scraper 72 from the filter screen 10. Then, with the rotation of the reciprocating screw 73, both the lower scraper 72 and the upper scraper 71 are driven back to their original positions. At this point, due to the ratchet structure 713, when the rack 715 drives the one-way gear 714 to rotate in the opposite direction, the lower scraper 72 cannot flip, allowing it to maintain its flipped state and return to its original position. Afterwards, the reciprocating screw 73 drives the upper scraper 71 and the lower scraper 72 again. 72 moves to the position of the cleaning component 9. During this process, the one-way gear 714 on the worm 711 contacts the rack 715 at the other end of the processing box 5. At this time, the one-way gear 714 on the worm 711 is driven to rotate by the rack 715 again. Similarly, the rotation of the one-way gear 714 drives the lower scraper 72 to flip again through the worm 711 and worm wheel 712, thereby flipping the lower scraper 72 to its original position. At this time, with the operation of the reciprocating screw 73, the lower scraper 72 cleans the debris remaining on the filter screen 10 again, thereby realizing the one-way cleaning of the filter screen 10 by the lower scraper 72, thus avoiding the problem that the lower scraper 72 will clean the filter screen 10 again on the return journey, and avoiding the accumulation of debris.

[0048] Example 3, see Figures 1-12Unlike Embodiment 2 described above, the pusher 8 includes a bent tube 81, which is fixedly connected to the processing box 5. A pressure rod 82 and a push rod 83 are slidably connected to the inner ends of the bent tube 81, respectively. The pressure rod 82 and push rod 83 are filled with hydraulic oil. A pressure plate 84 is fixedly connected to the end of the pressure rod 82 away from the bent tube 81. A return spring 85 is fixedly connected to the pressure plate 84, and the end of the return spring 85 away from the pressure plate 84 is fixedly connected to the bent tube 81. A fixing frame 86 is fixedly connected to the end of the push rod 83 away from the bent tube 81. A connecting spring 87 is fixedly connected to the fixing frame 86, and the end of the connecting spring 87 away from the fixing frame 86 is fixedly connected to the bent tube. When the slider 74 moves, it can contact the pressure plate 84. The cleaning component 9 includes an upper pipe 91 and a lower pipe 92. Both the upper pipe 91 and the lower pipe 92 are fixedly connected to the fixing frame 86, and the upper pipe 91 is distributed above the lower pipe 92. Several inclined nozzles 93 are provided on the upper pipe 91, and several arrayed inclined nozzles 94 are provided on the lower pipe 92. After the inclined nozzles 93 and the inclined nozzles 94 move down, they can blow air to clean the surfaces of the upper scraper 71 and the lower scraper 72. A three-way pipe 95 is fixedly connected to the end of the lower pipe 92 away from the inclined nozzles 94. The end of the three-way pipe 95 away from the lower pipe 92 is connected to the upper pipe 91. The three-way pipe 95 is connected to a high-temperature steam pipe.

[0049] After the scraper 7 moves, the upper scraper 71 contacts the pressure plate 84, and as the upper scraper 71 moves, it squeezes the pressure plate 84. At this time, the pressure plate 84 squeezes the pressure rod 82 and the return spring 85. The pressure rod 82 moves and transmits the pressure to the push rod 83 through hydraulic oil. Then the push rod 83 pushes out the fixing frame 86 and stretches the connecting spring 87. The movement of the fixing frame 86 drives the upper tube 91 and the lower tube 92 to move. The movement of the upper tube 91 drives the inclined nozzle 93 to move, and the movement of the lower tube 92 drives the tilted nozzle 94 to move. At this time, the inclined nozzle 93 and the tilted nozzle 94 spray high-temperature steam onto the surfaces of the upper scraper 71 and the lower scraper 72, thereby cleaning the surfaces of the upper scraper 71 and the lower scraper 72. After the upper scraper 71 separates from the pressure plate 84, the return spring 85 and the connecting spring 87 drive the pressure rod 82, the push rod 83 and the pressure plate 84 to reset.

[0050] It should be noted that both the upper tube 91 and the lower tube 92 are made of flexible hoses, and when the pusher 8 pushes the cleaning component 9 out, the upper tube 91 and the lower tube 92 will not affect the operation of the pusher 8 and the scraper 7.

[0051] Example 4, see Figures 1-12Unlike Embodiment 3 described above, the oil supply structure 43 includes a rotary joint 431 and circumferentially distributed oil outlet holes 432. The rotary joint 431 is located at one end of the sponge oiling roller 42, and a connecting pipe 433 is installed at the end of the rotary joint 431 away from the sponge oiling roller 42. The connecting pipe 433 is connected to the atomizing spray pipe 41, which is mounted on the conveyor frame 1. The oil outlet holes 432 are arrayed on the sponge oiling roller 42, and a sponge sleeve 4 is provided on the outer side of the sponge oiling roller 42. 34. Connecting pipe 433 delivers oil from the external oil pump to the atomizing nozzle 41 and the sponge oiling roller 42. Then, the atomizing nozzle 41 sprays out oil to coat the seaweed sheets. When the oil enters the sponge oiling roller 42, since the sponge oiling roller 42 is rotating at this time, under the action of centrifugal force, the oil is thrown out through the oil outlet 432 and then absorbed by the sponge sleeve 434 on the outside of the sponge oiling roller 42. Then, the sponge sleeve 434 coats the surface of the conveyor belt 2 with oil.

[0052] In actual use, an electric valve is also installed on the connecting pipe 433, and a photoelectric sensor is also installed below the atomizing nozzle 41. When the seaweed sheet moves to the bottom of the atomizing nozzle 41, the photoelectric sensor can detect it. Then, the external PLC controller drives the electric valve to open, and the oil in the connecting pipe 433 enters the atomizing nozzle 41 and is sprayed out.

[0053] Example 5, see Figures 1-12 Unlike the above embodiment four, the drive mechanism 3 includes a drive motor 31, which is fixedly connected to the conveyor frame 1. A main pulley 32 is fixedly connected to the output shaft of the drive motor 31. An auxiliary pulley 33 is driven to the outside of the main pulley 32.

The protective shell 34 is installed on the conveyor frame 1.

[0054] The main pulley 32 is driven to rotate by the drive motor 31. The rotation of the main pulley 32 drives the auxiliary pulley 33 to rotate. The rotation of the auxiliary pulley 33 drives the active roller on the inner side of the conveyor belt 2 to rotate. The rotation of the active roller drives the conveyor belt 2 to run. The operation of the conveyor belt 2 realizes the automatic feeding of seaweed sheets.

[0055] It should be noted that the inner drive connection of the conveyor belt 2 is a drive roller and a driven roller, both of which are rotatably connected to the conveyor frame 1. Since this is common knowledge known to those skilled in the art, it will not be described in detail again.
