Description

Technical Field

[0001] The invention relates to the technical field of kelp processing, in particular to an automatic double-sided high-pressure air knife kelp drying device. Background Art

[0002] Fresh kelp has a moisture content of up to 90% and is rich in mucus. This makes it prone to gluing and sticking during drying, leading to uneven drying or localized overheating, affecting quality. The fresh kelp drying process involves several key steps: automatic hanging, saltwater spray cleaning, double-sided high-pressure air knife drying, preheating and sweating, constant temperature dehumidification, heating and drying, cold air shaping, discharge sorting, and grading and packaging. Intelligent, automated, and precise control methods are employed to achieve an efficient, environmentally friendly, and energy-saving kelp drying process. The double-sided high-pressure air knife drying process uses high-pressure air knives to dry the kelp on both sides, removing excess moisture and preparing it for subsequent drying.

[0003] The existing technology for drying kelp requires that the kelp be hoisted and then blown on both sides, but the direction of wind acting on the kelp is fixed, and the kelp cannot be dried in all directions.

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figures 1 to 14 :

The transverse bracket 32 ​​is provided with a vertically extending second slide rail 321 on the side facing the first fixed bracket 21, and a second lifting frame 33 is slidably installed on the second slide rail 321. The auxiliary high-pressure air knife 3 is installed on the second lifting frame 33. The first lifting frame 22 and the second lifting frame 33 drive the main high-pressure air knife 2 and the auxiliary high-pressure air knife 3 to vertically lift and lower the kelp on the boom 12 to dry the kelp; a friction column 121 is coaxially provided at the top of the boom 12, and a driving wheel 34 for fitting with the friction column 121 is provided at the top of the transverse bracket 32. A transmission unit 35 is provided on the transverse bracket 32. When the second lifting frame 33 moves, it cooperates with the transmission unit 35 to drive the driving wheel 34 and the friction column 121 to rotate around the axis of the boom 12.

[0038] When the present invention is in use, the staff hangs the fresh kelp on the rotatably installed boom 12 on the movable seat 11 of the hanging conveyor belt 1, and the hanging conveyor belt 1 drives the boom 12 to move step by step, so that the kelp enters the drying station, and the first linear drive 311 drives the transverse bracket 32 ​​on the second fixed bracket 31 to move toward the first fixed bracket 21. The first linear drive 311 can be a cylinder, an oil cylinder or an electric push rod, etc. When the transverse bracket 32 ​​moves to the appropriate position, the main high-pressure air knife 2 and the auxiliary high-pressure air knife 3 are respectively located on both sides of the kelp, and then the main high-pressure air knife 2 and the auxiliary high-pressure air knife 3 are started, and the first lifting frame 22 is in the The first slide rail 211 on the first fixed bracket 21 slides, driving the main high-pressure air knife 2 to rise and fall vertically. The second lifting frame 33 slides on the second slide rail 321, driving the auxiliary high-pressure air knife 3 to rise and fall vertically. The main high-pressure air knife 2 and the auxiliary high-pressure air knife 3 are respectively located on both sides of the kelp to blow air from top to bottom. During the vertical lifting process, the second lifting frame 33 drives the drive wheel 34 to rotate through the transmission unit 35. The drive wheel 34 is in contact with the friction column 121 on the boom 12. Since the boom 12 is rotatably mounted on the movable base 11, the rotation of the drive wheel 34 can drive the friction column 121 and the boom 12 to rotate around their axis. During the rotation process, the main high-pressure air knife 2 and the auxiliary high-pressure air knife 3 continue to blow air, achieving all-round drying of the kelp. This embodiment provides a main high-pressure air knife 2 and an auxiliary high-pressure air knife 3 that can be raised and lowered vertically, and can adjust the height of the air knife according to the position of the kelp. When the second lifting frame 33 moves, the transmission unit 35 and the drive wheel 34 cooperate to drive the boom 12 and the kelp to rotate, so that the kelp is exposed to the wind in all directions during the drying process, and the moisture on the surface of the kelp is removed more quickly, thereby improving the production efficiency of the entire kelp drying process.

[0039] In order to solve the problem of how the transmission unit 35 realizes the rotation of the driving wheel 34 by utilizing the lifting of the second lifting frame 33, the following features are specifically provided:

[0040] The driving wheel 34 is rotatably mounted on a first extension frame 341 fixedly mounted on the top of the transverse bracket 32. The axis of the driving wheel 34 is vertically arranged. The first extension frame 341 extends horizontally toward the first fixed bracket 21 along the moving direction of the transverse bracket 32. A driven wheel 342 is rotatably mounted on the first extension frame 341. The axis of the driven wheel 342 is parallel to the driving wheel 34. The driving wheel 34 and the driven wheel 342 are connected to each other through a synchronous belt 343. The transmission unit 35 includes a first bevel gear 351 coaxially connected to the driven wheel 342, and a second bevel gear 352 meshing with the first bevel gear 351. The second bevel gear 352 rotates The second bevel gear 352 is installed on the first extension frame 341, and the axis of the second bevel gear 352 is horizontally arranged along the length direction of the first extension frame 341. The transmission gear 353 is coaxially installed on the second bevel gear 352; the transmission unit 35 also includes a transmission belt 354, which is meshed with the transmission gear 353. One end of the transmission belt 354 is fixedly connected to the top of the second lifting frame 33. When the second lifting frame 33 descends and drives the transmission belt 354 to move, the transmission gear 353, the second bevel gear 352, the first bevel gear 351, the driven wheel 342 and the driving wheel 34 rotate, and the driving wheel 34 contacts the friction column 121 to drive the boom 12 to rotate.

[0041] In this embodiment, when the boom 12 reaches the predetermined position, the first linear actuator 311 drives the traversing bracket 32 ​​on the second fixed bracket 31 toward the first fixed bracket 21. Once the traversing bracket 32 ​​has reached the desired position, the drive wheel 34 on the first extension bracket 341 engages one side of the friction post 121. The second lifting bracket 33 then begins to descend on the second slide rail 321. Because one end of a transmission belt 354 is fixedly connected to the top of the second lifting bracket 33, the descent of the second lifting bracket 33 drives the transmission belt 354. The transmission belt 354 can be a chain-type transmission belt, for example. As the transmission belt 354 moves, it interacts with the transmission gear 353, causing the transmission gear 353 to rotate. Because the transmission gear 353 is coaxially mounted with the second bevel gear 352, its rotation drives the second bevel gear 352 to rotate synchronously. Furthermore, because the second bevel gear 352 is meshed with the first bevel gear 351, its rotation drives the first bevel gear 351 to rotate. The first bevel gear 351 is coaxially connected to the driven wheel 342, and the rotation of the first bevel gear 351 will drive the driven wheel 342 to rotate. Since the driving wheel 34 and the driven wheel 342 are connected by a synchronous belt 343, the rotation of the driven wheel 342 will drive the driving wheel 34 to rotate through the synchronous belt 343. When the driving wheel 34 rotates, it fits the friction column 121, and drives the friction column 121 and the boom 12 to rotate around the axis of the boom 12 through friction, thereby realizing the rotation of the kelp during the drying process, so as to dry it in all directions. In this embodiment, while the second lifting frame 33 descends to blow the kelp, the driving wheel 34 rotates synchronously to drive the boom 12 to rotate, so that the blowing action of the wind knife and the rotation action of the kelp can be carried out synchronously, ensuring the continuity and efficiency of the drying process, improving the drying effect, and ensuring that the kelp can be dried in all directions and evenly.

[0042] In order to ensure that the transmission gear 353 can be driven to rotate by the transmission belt 354 when the second lifting frame 33 moves upward, the following features are specifically provided:

[0043] Several guide wheels 355 are rotatably installed on the top of the transverse bracket 32, and the transmission belt 354 is sleeved on the guide wheel 355. The axis of the guide wheel 355 is parallel to the axis of the transmission gear 353. A counterweight slider 356 is fixedly installed on the end of the transmission belt 354 away from the transverse bracket 32. The counterweight slider 356 is slidably installed on the longitudinal slide rail 357 set on the transverse bracket 32, and the longitudinal slide rail 357 extends in the vertical direction.

[0044] In this embodiment, after the boom 12 reaches the predetermined position, the second lifting frame 33 begins to descend on the second slide rail 321. Because a transmission belt 354 is connected to the second lifting frame 33 and is mounted on a plurality of guide wheels 355 rotatably mounted on the top of the transverse support 32, the second lifting frame 33 descends, driving one end of the transmission belt 354 downward. At this point, the other end of the transmission belt 354 pulls the counterweight slider 356 upward along the longitudinal slide rail 357. When the kelp is dried to a certain degree or is completely dried, the second lifting frame 33 begins to ascend. At this point, due to the weight of the counterweight slider 356, gravity causes it to slide downward along the longitudinal slide rail 357, driving the transmission belt 354 in the opposite direction. This reverse movement of the transmission belt 354 is also redirected by the guide wheels 355, again driving the transmission gear 353 to rotate. By setting the counterweight slider 356 and the guide wheel 355, no matter whether the second lifting frame 33 is rising or falling, the movement of the transmission belt 354 can be used to drive the transmission gear 353 to rotate, and then the drive wheel 34 can be rotated, ensuring that the boom 12 can continue to rotate during the entire drying process, achieving all-round and uniform drying of the kelp, and improving the drying effect and quality.

[0045] In order to ensure the friction transmission effect between the driving wheel 34 and the friction column 121, the following features are specifically set:

[0046] The top of the transverse bracket 32 ​​is slidably installed with a second extension bracket 344 which is arranged parallel to the first extension bracket 341. The second extension bracket 344 is rotatably installed with a pressing wheel 345 at one end away from the transverse bracket 32. The axis of the pressing wheel 345 is parallel to the axis of the driving wheel 34. At least two second guide rods 346 perpendicular to the second extension bracket 344 are provided on the second extension bracket 344. The second guide rods 346 are inserted into the first extension bracket 341. A limiting head 347 is provided at one end of the second guide rod 346 away from the second extension bracket 344. A first spring 348 is sleeved on the second guide rod 346. The first spring 348 elastically connects the first extension bracket 341 and the limiting head 347. The elastic force of the first spring 348 makes the second extension bracket 344 approach the first extension bracket 341, and the pressing wheel 345 cooperates with the driving wheel 34 to clamp the friction column 121.

[0047] In this embodiment, after the boom 12 reaches the predetermined position, the first linear actuator 311 drives the transverse bracket 32 ​​to move toward the first fixed bracket 21. During the movement of the transverse bracket 32, the driving wheel 34 and the pressing wheel 345 gradually approach the friction column 121. As the transverse bracket 32 ​​moves, when the driving wheel 34 contacts the friction column 121, the pressing wheel 345 also contacts the friction column 121. Since the second extension frame 344 is slidably mounted on the top of the transverse bracket 32, the second extension frame 344 can drive the pressing wheel 345 to move along the surface of the friction column 121, and the second extension frame 344 moves away from the first extension frame 341. Finally, the pressing wheel 345 cooperates with the driving wheel 34 to clamp the friction column 121. The elastic force of the first spring 348 maintains close contact between the pressing wheel 345, the driving wheel 34 and the friction column 121. In this embodiment, the friction column 121 is clamped by the pressing wheel 345 in cooperation with the driving wheel 34, thereby increasing the friction between the driving wheel 34 and the friction column 121, ensuring that the driving wheel 34 can stably drive the friction column 121 to rotate, so that the kelp can continuously and stably rotate in all directions during the drying process, thereby improving the drying effect and quality.

[0048] In order to ensure that there is enough clearance between the pressing wheel 345 and the driving wheel 34 to allow the friction column 121 to be inserted, the following features are specifically provided:

[0049] A limit baffle 349 is fixedly installed on the top of the transverse moving bracket 32 ​​, and the limit baffle 349 is located between the first extension frame 341 and the second extension frame 344 .

[0050] In this embodiment, the limit baffle 349 is located between the first extension frame 341 and the second extension frame 344. The elastic force of the first spring 348 causes the second extension frame 344 to fit into the limit baffle 349 when the pressing wheel 345 does not contact the friction column 121, ensuring that there is sufficient clearance between the pressing wheel 345 and the driving wheel 34 to allow the friction column 121 to be inserted.

[0051] In order to ensure that the driving wheel 34 and the pressing wheel 345 are precisely aligned with both sides of the friction column 121 when the transverse moving bracket 32 ​​stops moving, the following features are specifically provided:

[0052] A plurality of first positioning rods 212 are provided on the top of the first fixed bracket 21 and extend horizontally toward one side of the transverse bracket 32. A second positioning rod 322, the same number as the first positioning rod 212 and located on the same straight line, is fixedly installed on the top of the transverse bracket 32. When the transverse bracket 32 ​​moves toward the first fixed bracket 21 until the second positioning rod 322 is in contact with the first positioning rod 212, the driving wheel 34 and the pressing wheel 345 are respectively in contact with both sides of the friction column 121.

[0053] In this embodiment, the first linear actuator 311 drives the transverse bracket 32 ​​to move toward the first fixed bracket 21. During the movement of the transverse bracket 32, the driving wheel 34 and the pressing wheel 345 move toward the friction column 121 along with the transverse bracket 32. When the transverse bracket 32 ​​continues to move toward the first fixed bracket 21 until the second positioning rod 322 on the transverse bracket 32 ​​abuts the first positioning rod 212 on the first fixed bracket 21, the driving wheel 34 and the pressing wheel 345 can then be precisely affixed to both sides of the friction column 121. By providing the first positioning rod 212 and the second positioning rod 322, this embodiment provides a precise positioning reference for the movement of the transverse bracket 32. When the second positioning rod 322 abuts the first positioning rod 212, it can ensure that the driving wheel 34 and the pressing wheel 345 are precisely affixed to both sides of the friction column 121, ensuring effective contact and stable transmission between the driving wheel 34 and the friction column 121 during the rotary drying of the kelp, thereby improving the drying effect and quality.

[0054] In order to ensure the stability of the lateral moving bracket 32 ​​during horizontal movement, the following features are specifically set:

[0055] A plurality of horizontally extending first guide rods 323 are provided on one side of the transverse bracket 32 ​​facing the second fixed bracket 31 . The first guide rods 323 are inserted into first guide sleeves 312 provided on the second fixed bracket 31 .

[0056] In this embodiment, the cooperation between the first guide rod 323 and the first guide sleeve 312 provides stable guidance and support for the horizontal movement of the transverse bracket 32, effectively preventing the transverse bracket 32 ​​from shaking, deflecting or tilting during movement, and ensuring that the transverse bracket 32 ​​can accurately move along the predetermined horizontal direction.

[0057] In order to achieve the purpose of synchronously raising and lowering the main high-pressure air knife 2 and the auxiliary high-pressure air knife 3 for drying, the following features are specifically set:

[0058] A second linear driver 324 is fixedly mounted on the transverse bracket 32, and the second lifting frame 33 is fixedly mounted on the working end of the second linear driver 324, and the working end of the second linear driver 324 is set to move in the vertical direction; both ends of the second lifting frame 33 are respectively provided with connecting rods 331 extending horizontally toward the first lifting frame 22, and the first lifting frame 22 is provided with a connecting sleeve 221 extending toward one side of the first lifting frame 22. When the first linear driver 311 drives the transverse bracket 32 ​​to move until the second positioning rod 322 is in contact with the top block 222, the connecting rod 331 is inserted into the connecting sleeve 221 to make the first lifting frame 22 and the second lifting frame 33 rise and fall synchronously.

[0059] In this embodiment, the first linear actuator 311 drives the transverse bracket 32 ​​toward the first fixed bracket 21. During this movement, the second positioning rod 322 on the transverse bracket 32 ​​gradually approaches the first positioning rod 212 on the first fixed bracket 21. When the transverse bracket 32 ​​moves until the second positioning rod 322 abuts the first positioning rod 212, the connecting rod 331 on the second lifting frame 33 fits neatly into the connecting sleeve 221 of the first lifting frame 22, integrally connecting the first and second lifting frames 22 and 33. The second linear actuator 324, which can be a linear slide, is activated. Its working end moves vertically, driving the second lifting frame 33 upward and downward. Because the first and second lifting frames 22 and 33 are connected via the connecting rod 331 and connecting sleeve 221, the first lifting frame 22 moves synchronously with the second lifting frame 33. Consequently, the main and auxiliary high-pressure air knives 2 and 3 descend simultaneously, drying the kelp on the boom 12 on both sides. When the kelp is dried, the second linear actuator 324 drives the second lifting frame 33 to rise, and the first lifting frame 22 rises synchronously. Afterwards, the first linear actuator 311 drives the transverse bracket 32 ​​to move away from the first fixed bracket 21, and the connecting rod 331 is pulled out of the connecting sleeve 221. The first lifting frame 22 and the second lifting frame 33 return to their initial state, waiting for the next kelp to enter the drying area to repeat the above process. This embodiment ensures that the main high-pressure air knife 2 and the auxiliary high-pressure air knife 3 can be raised and lowered synchronously through the cooperation of the connecting rod 331 and the connecting sleeve 221, as well as the drive of the second linear actuator 324. During the drying process, the connecting rod 331 and the connecting sleeve 221 cooperate with the first lifting frame 22 and the second lifting frame 33 to limit the kelp, preventing the kelp from flying around due to the wind, thereby improving the quality and effect of the kelp drying.

[0060] In order to solve the problem of how to ensure that the connecting rod 331 can be accurately inserted into the connecting sleeve 221 in the initial state, the following features are specifically set:

[0061] The first fixing bracket 21 is provided with a magnetic positioning block 213 on one side of the first slide rail 211, and the first lifting frame 22 is provided with a top block 222 located directly below the magnetic positioning block 213. A magnet 223 is provided on the top of the top block 222. The magnet 223 attracts the magnetic positioning block 213 to fix the first lifting frame 22 at the highest position on the first slide rail 211; the second positioning rod 322 is provided with a first positioning block 325. When the second lifting frame 33 moves up to fit the bottom of the first positioning block 325, the connecting rod 331 and the connecting sleeve 221 are in the same straight line.

[0062] In the initial state of this embodiment, the magnet 223 on the top block 222 of the first lifting frame 22 is attracted to the magnetic positioning block 213 on the first fixed bracket 21, thereby securing the first lifting frame 22 at the highest position of the first slide rail 211. Simultaneously, the second lifting frame 33 moves upward before operation and stops when it abuts the bottom of the first positioning block 325 on the second positioning rod 322. In this position, the connecting rod 331 and the connecting sleeve 221 are aligned. Therefore, when the first linear actuator 311 drives the transverse bracket 32 ​​toward the first fixed bracket 21, the connecting rod 331 can be precisely inserted into the connecting sleeve 221. In this embodiment, by setting the magnetic positioning block 213, the top block 222, the magnet 223 and the first positioning block 325, it is ensured that the connecting rod 331 and the connecting sleeve 221 are in the same straight line in the initial state, thereby ensuring that when the transverse bracket 32 ​​moves into place, the connecting rod 331 can be accurately inserted into the connecting sleeve 221, realizing a reliable connection between the first lifting frame 22 and the second lifting frame 33, ensuring that the main high-pressure air knife 2 and the auxiliary high-pressure air knife 3 can be raised and lowered synchronously, and improving the accuracy and effect of blow-drying.

[0063] In order to achieve the purpose of being able to adjust the air outlet direction of the main high-pressure air knife 2 and the auxiliary high-pressure air knife 3, the following features are specifically set:

[0064] Both ends of the main high-pressure air knife 2 and the auxiliary high-pressure air knife 3 are provided with a shaft 23. The main high-pressure air knife 2 and the auxiliary high-pressure air knife 3 are respectively rotatably mounted on the first lifting frame 22 and the second lifting frame 33 through the shaft 23. The outer wall of the shaft 23 is provided with a plurality of spline grooves 231 extending along the axis direction of the shaft 23. A spline sleeve is slidably mounted on the spline groove 231. An adjusting ring 233 is coaxially provided on the spline sleeve. The adjusting ring 233 is provided with a plurality of positioning holes 234 distributed at equal angles around the axis of the shaft 23. Both ends of the first lifting frame 22 and the second lifting frame 33 are provided with locking rods 224 with the same diameter as the positioning holes 234. The locking rods 224 are inserted into different positioning holes 234 to adjust the air outlet angles of the main high-pressure air knife 2 and the auxiliary high-pressure air knife 3; a limiting ring 235 is provided at the top of the shaft rod 23, and a second spring 236 is sleeved on the shaft rod 23. The second spring 236 elastically connects the adjusting ring 233 and the limiting ring 235, and the elastic force of the second spring 236 pushes the adjusting ring 233 to fit the locking rod 224.

[0065] In this embodiment, to adjust the airflow angle of the main high-pressure air knife 2 or the auxiliary high-pressure air knife 3, the user first overcomes the force of the second spring 236 and pushes the adjustment ring 233 upward along the shaft 23, separating the adjustment ring 233 from the locking rod 224. The splined sleeve then slides on the spline groove 231, causing the adjustment ring 233 to rotate about the shaft 23. The adjustment ring 233 is rotated to align the various positioning holes 234 with the locking rod 224. The user selects the appropriate positioning hole 234 based on their actual drying needs, then releases the adjustment ring 233. Under the force of the second spring 236, the adjustment ring 233 moves downward until it again engages the locking rod 224. The locking rod 224 then inserts into the newly selected positioning hole 234, securing the new airflow angle of the main high-pressure air knife 2 or the auxiliary high-pressure air knife 3. This embodiment, through the coordination of the locking rod 224 with the various positioning holes 234, allows for convenient adjustment of the airflow angles of the main high-pressure air knife 2 or the auxiliary high-pressure air knife 3. The air outlet direction of the wind knife can be flexibly adjusted according to the shape, thickness and different drying stages of the kelp, so that the wind force acts on the kelp more accurately, improving the drying effect and quality and meeting different drying needs.

[0066] Working principle: The staff hangs the fresh kelp on the boom 12 rotatably installed on the movable seat 11 of the lifting conveyor belt 1. The lifting conveyor belt 1 drives the boom 12 to move step by step, so that the kelp enters the drying station. The first linear drive 311 drives the transverse bracket 32 ​​on the second fixed bracket 31 to move toward the first fixed bracket 21. When the transverse bracket 32 ​​moves to the appropriate position, the main high-pressure air knife 2 and the auxiliary high-pressure air knife 3 are respectively located on both sides of the kelp. Then the main high-pressure air knife 2 and the auxiliary high-pressure air knife 3 are started. The main high-pressure air knife 2 and the auxiliary high-pressure air knife 3 are respectively located on both sides of the kelp to blow the kelp from top to bottom; during the vertical lifting process, the second lifting frame 33 drives the driving wheel 34 to rotate through the transmission unit 35, and the driving wheel 34 is in contact with the friction column 121 on the boom 12. Since the boom 12 is rotatably installed on the movable seat 11, the driving wheel 34 can drive the friction column 121 and the boom 12 to rotate around its axis when it rotates. During the rotation process, the main high-pressure air knife 2 and the auxiliary high-pressure air knife 3 continue to blow air to achieve all-round drying of the kelp.
