Description

Technical Field

[0001] This utility model relates to the field of kelp processing technology, and more specifically, to a drying device that can be used to dry kelp. Background Technology

[0002] As is well known, kelp is a highly nutritious seafood. Kelp is a brown algae with a brown thallus. Kelp consists of three parts: the holdfast, the stipe, and the blades. The holdfast is forked and used to attach to rocks on the seabed; the stipe is short, thick, and cylindrical; and the blades are narrow and ribbon-shaped.

[0003] Currently, naturally growing kelp is scarce, and it mainly relies on artificial cultivation. The artificial cultivation method involves setting up multiple rows of cultivation racks consisting of numerous floating structures in the sea. Several seedling ropes are tied between every two rows of racks, and the kelp grows on these ropes. Once the kelp matures, fishermen use small boats to dredge it from the sea, transport it ashore, and then process it.

[0004] Fresh kelp is typically dried to produce dried kelp. The drying process can be referenced in utility model patents CN216668237U and CN216662198U. The drying process usually takes place in a drying room equipped with a conveyor chain that allows the kelp to move, enabling automated and continuous batch drying. Fresh kelp is connected one by one to the conveyor chain. Typically, operators manually pick up the fresh kelp and hang it on hooks or hangers on the conveyor. These hooks or hangers are positioned at a certain height above the ground to ensure the kelp spreads out vertically, suspended in mid-air. Because the fresh kelp is large, heavy, and has a smooth surface, this process is inconvenient, time-consuming, labor-intensive, inefficient, and costly for workers.

[0005] In addition, after the kelp on the conveyor chain is dried in the drying room, the kelp is very dry. The very dry kelp needs to be removed from the conveyor chain, which is the unloading operation. During the unloading operation, the dry kelp is easily broken and damaged. The occurrence of damage is also not conducive to the realization of automated unloading operation. Summary of the Invention

When the second follow-up clamp opening and closing drive device 600 is in the initial state, the extension rod of the second blocking cylinder is in the extended state.

[0074] like Figure 4 , 9As shown in Figure 12, the second connecting column of the second follower-type clamp opening and closing drive device 600 is fixedly connected to the extension portion 202-1 of the horizontal frame 202, and the second finger cylinder connecting bracket passes through the displacement channel 202-1-2 of the second finger cylinder connecting bracket. The second follower-type clamp opening and closing drive device 600 is located above the suspension chain 204. A sensor can be set for the second follower-type clamp opening and closing drive device 600. The sensor is set in the same way as the sensor 312, and its function is also the same as that of the sensor 312.

[0075] like Figure 25-29As shown, the automatic feeding device 400 includes a vertical column 401, a horizontal beam 402, a rotating shaft 403, a rotating support plate 404, a winch connecting rod 405, a winch 406, a wire rope 408, a rotating drive cylinder 409, a connecting piece 410, a drive chain 411, a large sprocket 412, a small sprocket 413, an upper bearing seat 414, a lower bearing seat 415, a one-way bearing 416, and a gripper 417. The horizontal beam 402 is fixedly connected to the top of the vertical column 401. The upper bearing seat 414 is connected to the horizontal beam 402, and the lower bearing seat 415 is connected to the horizontal beam 402. The upper bearing seat 414 and the lower bearing seat 415 are equipped with bearings. The rotating shaft 403 is connected to the bearing in the upper bearing seat 414 and the bearing in the lower bearing seat 415. Shaft 403 can rotate under the support of upper bearing seat 414 and lower bearing seat 415. Rotating support plate 404 is fixedly connected to shaft 403. Winch connecting rod 405 is fixedly connected to rotating support plate 404. Winch 406 is fixedly installed on winch connecting rod 405. Winch 406 is provided with winding wheel 407. Wire rope 408 is wound on winding wheel 407. Rotating drive cylinder 409 is connected to horizontal beam 402. Small sprocket 413 is rotatably connected to horizontal beam 402. Large sprocket 412 is connected to the top of shaft 403 through one-way bearing 416. Drive chain 411 is connected between large sprocket 412 and small sprocket 413. Telescopic rod of rotating drive cylinder 409 is fixedly connected to drive chain 411 through connector 410. Gripper 417 is connected to the end of wire rope 408. The diagram shows the extension rod of the rotary drive cylinder 409 in the extended state. When the extension rod of the rotary drive cylinder 409 retracts, it pulls the drive chain 411 backward through the connector 410. At this time, the one-way bearing 416 is locked. The large sprocket 412 rotates, driving the rotating shaft 403 to rotate. The rotating shaft 403 rotates, driving the rotating support plate 404 and the winch connecting rod 405 to rotate, thereby causing the winch 406 to rotate at a certain angle. Then, the extension rod of the rotary drive cylinder 409 extends, and the extension rod... The drive chain 411 is pulled forward through the connector 410. At this time, the one-way bearing 416 is not locked, the large sprocket 412 rotates, while the shaft 403 remains stationary. Therefore, the reciprocating motion of the extension rod of the drive cylinder 409 enables the winch 406 to rotate in one direction on the horizontal plane. That is, when the extension rod of the drive cylinder 409 retracts, the winch 406 rotates a certain angle. After a period of time, when the extension rod of the drive cylinder 409 retracts again, the winch 406 rotates a certain angle. Multiple winches 406 are set up. The figure shows 6 winches as an example. The 6 winches are evenly distributed along the circumference, and the 6 winches correspond to 6 wire ropes. The 6 wire ropes correspond to 6 grippers.

[0076] The gripper 417 is used to hold fresh kelp to be dried. When the winch 406 operates, the winding reel 407 rotates, releasing the wire rope 408 downwards, causing the gripper 417 to descend close to the ground. When the winding reel 407 reverses direction, it raises the gripper 417. To more accurately determine the number of clockwise or counterclockwise rotations of the winding reel 407, refer to... Figure 28 The system can be configured with a screw support 418, a screw 419, a nut seat 420, a guide optical shaft 421, a base 422, a first limit sensor 423, and a second limit sensor 424. The screw 419 is rotatably connected to the screw support 418, and the nut seat 420 is connected and engaged with the screw 419. The two guide optical shafts 421 are connected between the screw support 418 and pass through the nut seat 420, allowing the nut seat 420 to slide along the guide optical shafts 421. The screw support 418 is fixedly mounted on the base 422, and the first and second limit sensors 423 are mounted on the side of the screw support 418. The base 422 is fixedly mounted on the winch connecting rod 405. The central shaft of the winding wheel 407 is connected to the end of the screw 419. When the winding wheel 407 rotates, the central shaft of the winding wheel 407 drives the screw 419 to rotate, and the nut seat 420 moves. When the nut seat 420 moves to the position of limit sensor 1 423, limit sensor 1 423 sends a signal to the controller, and the controller stops the winch according to the signal. When the nut seat 420 moves to the position of limit sensor 2 424, limit sensor 2 424 sends a signal to the controller, and the controller stops the winch according to the signal.

[0077] refer to Figure 29 One specific implementation of the gripper 417 can be as follows: it includes a finger cylinder 417-1, a first clamping plate 417-2, and a second clamping plate 417-3. The first clamping plate 417-2 and the second clamping plate 417-3 are respectively connected to finger one and finger two of the finger cylinder 417-1. The end of the wire rope 408 is connected to the cylinder body of the finger cylinder 417-1. As shown in the figure, finger one and finger two are in a closed state, at which time the first clamping plate 417-2 and the second clamping plate 417-3 are closed. When finger one and finger two are opened, the first clamping plate 417-2 and the second clamping plate 417-3 are opened. When the first clamping plate 417-2 and the second clamping plate 417-3 are closed, they grip the seaweed laterally, and the first clamping plate 417-2 and the second clamping plate 417-3 are located on a horizontal plane.

[0078] refer to Figure 1 , 2 4, 8, The winch of the automatic feeding device 400 approaches the first follow-up clamp opening and closing drive device 300.

[0079] like Figure 30 , 31The automatic unloading device 700 includes a belt conveyor 701, a lifting mechanism 702, a rotary cylinder 703, a suction cup connecting plate 704, suction cups 705, and a cylinder 706. The lifting mechanism 702 is fixedly mounted on the frame of the belt conveyor 701. The rotary cylinder 703 is connected to the lifting mechanism 702, and the lifting mechanism 702 can drive the rotary cylinder 703 to rise or fall. The cylinder 706 is connected to the output end of the rotary cylinder 703, and when the rotary cylinder 703 rotates 90°, it can cause the cylinder 706 to rotate 90°. The suction cup connecting plate 704 is connected to the telescopic rod of the cylinder 706. Multiple suction cups 705 are connected to the suction cup connecting plate 704. The belt conveyor 701 is equipped with a conveyor belt 701-1. The lifting mechanism 702 can be a ball screw linear module, and the rotary cylinder 703 is fixed on the slider of the ball screw linear module. The figure shows that the automatic feeding device 700 is in the state where the telescopic rod of the cylinder 706 is extended and the suction cup connecting plate 704 is located in the vertical plane.

[0080] refer to Figure 1 , 3 4, 9, The automatic feeding device 700 is close to the second follow-up clamp opening and closing drive device 600, and the suction cup connecting plate 704 is located below the second follow-up clamp opening and closing drive device 600.

[0081] The working process of the above-mentioned automatic kelp drying equipment is described in detail below:

[0082] The first step is to prepare fresh kelp to be dried. Place the fresh kelp under the automatic feeding device 400. Operator A stands on the ground and operator B stands on the platform 500.

[0083] In the second step, the first winch 406 rotates forward to release the wire rope, and the corresponding clamp 417 descends to operator A. Then, the clamp 417 opens, and operator A picks up a piece of fresh kelp and places it in the clamp 417. The clamp 417 then closes to hold the fresh kelp. For example, the first clamp 417-2 and the second clamp 417-3 can be used to hold the upper middle part of the fresh kelp in the lateral direction.

[0084] In the third step, the first winch 406 reverses to retract the wire rope, and the corresponding gripper 417 rises, carrying the first fresh seaweed up to a position close to the first follow-up clamp opening and closing drive device 300.

[0085] In the fourth step, the telescopic rod of the rotary drive cylinder 409 of the automatic feeding device 400 retracts, causing the first winch 406 to rotate at a certain angle, further allowing the gripper 417 to bring the first fresh kelp closer to the first follow-up clamp opening and closing drive device 300; the telescopic rod of the rotary drive cylinder 409 extends.

[0086] Fifth step, operator B on platform 500 transfers the first piece of fresh kelp.

[0087] In step S501, in the initial state, the first follow-up clamp opening and closing drive device 300 is in the following state: the first horizontal rodless cylinder 301 is not supplied with compressed air (the moving block 301-1 can move freely); the telescopic rod of the first vertical cylinder 302 is retracted; the two fingers of the left finger cylinder 305 and the two fingers of the right finger cylinder 306 are open; the telescopic rod of the first blocking cylinder 307 is extended; and the first blocking block 308 is located above the suspension chain 204 and below the track formed by square tube 1 203-1 and square tube 2 203-2. Figure 15 and 16 As shown.

[0088] In step S502, as the suspension chain 204 moves forward, the clamp is initially in a closed state. When the clamp moves below the first follow-up clamp opening and closing drive device 300, the first blocking block 308 blocks the front of the connecting rod 210. The connecting rod 210 touches the first blocking block 308 and pushes the first blocking block 308 forward, thereby moving the first blocking cylinder connecting bracket 303 forward (moving block 301-1 moves forward). The sensor 312 immediately generates a signal and feeds the signal back to the controller as the first blocking cylinder connecting bracket 303 moves forward. The first blocking cylinder connecting bracket 303, the first vertical cylinder 302, the first finger cylinder connecting bracket 304, the left finger cylinder 305, and the right finger cylinder 306 all move forward simultaneously, that is, move synchronously with the suspension chain 204.

[0089] In step S503, the controller then instructs the extension rod of the first vertical cylinder 302 to extend, thereby causing the left finger cylinder 305 and the right finger cylinder 306 to descend. The two fingers of the left finger cylinder 305 are positioned on either side of the top of the clamp, and the two fingers of the right finger cylinder 306 are also positioned on either side of the top of the clamp. Figure 32 and 33 As shown;

[0090] In step S504, the controller then instructs the left finger cylinder 305 and the right finger cylinder 306 to operate simultaneously. The two fingers of the left finger cylinder 305 and the two fingers of the right finger cylinder 306 close, thereby clamping the top of the clamp and opening the clamp from its closed state.

[0091] Step S505: Next, operator B moves the first fresh kelp to the open gripper.

[0092] In step S506, next, operator B steps on the foot switch, which sends a corresponding signal to the controller. The controller instructs the two fingers of the left finger cylinder 305 and the two fingers of the right finger cylinder 306 to open, thereby closing the clamp in the open state, and thus clamping the kelp (for example, the clamp can clamp the top of fresh kelp).

[0093] Step S507: Next, open the gripper corresponding to the first winch.

[0094] In step S508, the telescopic rod of the first blocking cylinder 307 retracts, causing the first blocking block 308 to move backward and retract, so that the first blocking block 308 no longer blocks the front of the connecting rod 210; the telescopic rod of the first vertical cylinder 302 retracts, thereby causing the left finger cylinder 305 and the right finger cylinder 306 to rise to their initial positions; at the same time as the telescopic rod of the first vertical cylinder 302 retracts, compressed air is supplied to the first horizontal rodless cylinder 301, causing the first horizontal rodless cylinder 301 to actuate, causing the moving block 301-1 to move backward back to its initial position. At this time, the first blocking cylinder connecting bracket 303, the first vertical cylinder 302, the first finger cylinder connecting bracket 304, the left finger cylinder 305, and the right finger cylinder 306 all move backward back to their initial positions.

[0095] In step S510, the telescopic rod of the first blocking cylinder 307 extends, causing the first blocking block 308 to move forward; the first blocking block 308 is ready to block the next connecting rod 210. At this time, the transfer of the first fresh kelp is completed.

[0096] Step 6: While performing step 5 above (while operator B on platform 500 is operating), the second winch rotates forward to release the wire rope, and the corresponding gripper descends to operator A. Operator A clamps the second fresh kelp with the gripper, and the second winch reverses to retract the wire rope. The corresponding gripper rises, and the gripper, carrying the second fresh kelp, rises to a position close to the first follow-up clamp opening and closing drive device 300.

[0097] In the seventh step, the telescopic rod of the rotary drive cylinder 409 of the automatic feeding device 400 retracts, causing the second winch to rotate at a certain angle, further allowing the gripper to bring the second fresh kelp closer to the first follow-up clamp opening and closing drive device 300; the telescopic rod of the rotary drive cylinder 409 extends.

[0098] Step 8: Following step 5 above, operator B on platform 500 transfers the second piece of fresh kelp.

[0099] While operator B on platform 500 is operating the second fresh kelp, the third winch rotates forward to release the wire rope, and the corresponding gripper descends to operator A. Operator A uses the gripper to clamp the third fresh kelp. The third winch reverses to retract the wire rope, and the corresponding gripper, carrying the third fresh kelp, rises to a position close to the first follow-up clamp opening and closing drive device 300.

[0100] By repeating the above steps, continuous kelp feeding, kelp transfer, and kelp clamping actions can be achieved, meeting the requirements of automated and efficient batch operations.

[0101] It is evident that automatic kelp feeding has been achieved, increasing the level of automation, reducing manpower consumption, lowering labor intensity, reducing labor costs, and improving operational efficiency. The follow-up clamp drive device operates stably and reliably, and the automatic feeding process is also reliable and stable.

[0102] It should be noted that setting the first guide plate 309 and the second guide plate 310 is a better technical means. When the left finger cylinder 305 and the right finger cylinder 306 descend, there may be occasional situations where the top of the clamp cannot be aligned. The first guide plate 309 and the second guide plate 310 can play a guiding role, so that the top of the clamp can enter the space between the two fingers of the left finger cylinder 305 more smoothly, and enter the space between the two fingers of the right finger cylinder 306 more smoothly.

[0103] It should be noted that the sensor 312 can be omitted, and instead, the operator can manually observe and determine that the clamp has moved below the follow-up clamp drive device 300.

[0104] Suspension chain 204 according to Figure 3 , 10 The clamps operate in the direction indicated by arrows 12 and 18. The clamps, carrying fresh kelp, enter the box through the first window 101-3 at the rear of box 101. Hot air inside the box dries the fresh kelp. The fresh kelp moves along the path of the S-shaped section 204-1 of the suspension chain 204. When the fresh kelp reaches the return section 204-2 of the suspension chain 204, it has already been dried. The dried kelp then passes through the bend 204-2-1 of the suspension chain 204 and exits through the second window 101-4 at the rear of box 101. After exiting through the second window 101-4, the dried kelp moves to the second follow-up clamp opening and closing drive device 600. Automatic feeding is performed at the second follow-up clamp opening and closing drive device 600. The specific process of automatic feeding is as follows:

[0105] In step S901, the second follow-up clamp opening and closing drive device 600 is in its initial state. The second horizontal rodless cylinder is not supplied with compressed air (the moving block can move freely), the telescopic rod of the second vertical cylinder is in the retracted state, the two fingers of the left finger cylinder are in the open state, the two fingers of the right finger cylinder are in the open state, the telescopic rod of the second blocking cylinder is in the extended state, the second blocking block is located above the suspension chain 204, and the second blocking block is located below the track formed by square tube 1 203-1 and square tube 2 203-2.

[0106] In step S902, as the suspension chain 204 moves forward, the clamp is initially in a closed state (the clamp is holding dried seaweed). When the clamp moves below the second follow-up clamp opening and closing drive device 600, the second blocking block blocks in front of the connecting rod 210. The connecting rod 210 touches the second blocking block forward and pushes the second blocking block forward, thereby moving the second blocking cylinder connecting bracket forward. The sensor that moves the second blocking cylinder connecting bracket forward immediately generates a signal and feeds the signal back to the controller. The second blocking cylinder connecting bracket, the second vertical cylinder, the second finger cylinder connecting bracket, the left finger cylinder, and the right finger cylinder all move forward simultaneously, that is, they move synchronously with the suspension chain 204.

[0107] In step S903, the controller instructs the extension rod of cylinder 706 in the automatic feeding device 700 to extend. The suction cup connecting plate 704, carrying the suction cups 705, moves horizontally to the side of the dried kelp. The vacuum generator activates the suction cups 705, causing multiple suction cups 705 to adhere to the side of the dried kelp. At this point, the dried kelp is in a vertical plane (the side of the dried kelp refers to the front or back). If the suction cup connecting plate 704 and suction cups 705 are in front of the dried kelp, the dried kelp will move forward and come close to the suction cups 705, in which case the suction cups will adhere to the front of the dried kelp. If the suction cup connecting plate 704 and suction cups 705 are behind the dried kelp, the suction cups will adhere to the back of the dried kelp.

[0108] When the telescopic rod of cylinder 706 in the automatic feeding device 700 extends, the controller commands the telescopic rod of the second vertical cylinder to extend, thereby driving the left finger cylinder and the right finger cylinder to descend. The two fingers of the left finger cylinder are located on both sides of the top of the clamp, and the two fingers of the right finger cylinder are also located on both sides of the top of the clamp.

[0109] In step S904, the controller then instructs the left and right finger cylinders to operate simultaneously. The two fingers of the left finger cylinder close, and the two fingers of the right finger cylinder close, thereby clamping the top of the clamp and opening the clamp from its closed state.

[0110] In step S905, the telescopic rod of cylinder 706 in the automatic feeding device 700 retracts, and the suction cup connecting plate 704 moves the dried seaweed to above the conveyor belt 701-1 of the belt conveyor 701. Then, the rotary cylinder 703 rotates the suction cup connecting plate 704 90°, so that the suction cup connecting plate 704 is on the horizontal plane, and the dried seaweed is also on the horizontal plane. Then, the lifting mechanism 702 moves the rotary cylinder 703 down, and the suction cup connecting plate 704, carrying the dried seaweed, descends to a position close to the conveyor belt. Position 701-1; then inflate suction cup 705, the suction force of suction cup 705 disappears, and the dried kelp falls onto conveyor belt 701-1; conveyor belt 701-1 then transports the dried kelp for collection; then lifting mechanism 702 actuates to raise rotary cylinder 703, rotary cylinder 703 actuates to rotate suction cup connecting plate 704 90°, suction cup connecting plate 704 is now on the horizontal plane, extension rod of cylinder 706 extends, and suction cup on suction cup connecting plate 704 is ready to pick up the next dried kelp.

[0111] In step S906, the controller instructs the two fingers of the left finger cylinder to open and the two fingers of the right finger cylinder to open, thereby closing the clamp in the open state. At this time, the clamp is ready to clamp fresh kelp at the loading station.

[0112] In step S907, the telescopic rod of the second blocking cylinder retracts, causing the second blocking block to move backward and retract, so that the second blocking block no longer blocks the front of the connecting rod 210; the telescopic rod of the second vertical cylinder retracts, causing the left finger cylinder and the right finger cylinder to rise to their initial positions; at the same time as the telescopic rod of the second vertical cylinder retracts, compressed air is supplied to the second horizontal rodless cylinder, causing the second horizontal rodless cylinder to move backward and return to its initial position. At this time, the second blocking cylinder connecting bracket, the second vertical cylinder, the second finger cylinder connecting bracket, the left finger cylinder, and the right finger cylinder all move backward and return to their initial positions.

[0113] In step S908, the telescopic rod of the second blocking cylinder extends, causing the second blocking block to move forward; the second blocking block prepares to block the next connecting rod. At this point, the automatic feeding of dried kelp is completed.

[0114] It is evident that the automatic feeding of dried kelp has been achieved, which improves the level of automation, reduces manpower consumption, lowers labor intensity, reduces labor costs, and improves the efficiency of feeding operations.

[0115] It should be noted that when using the suction cup 705 to adhere to the side of dried kelp, the best position to adhere to is the upper-middle part of the dried kelp, because the upper-middle part of the dried kelp is thicker and easier to adhere to.

[0116] Inside the container, the fresh kelp is already quite dry when it reaches the return section 204-2 of the suspension chain 204. Due to the high humidity at the bend 204-2-1, the very dry kelp is slightly moistened at this point, preventing breakage and damage. This also facilitates more reliable suction of the kelp by the suction cups of the automatic feeding device, improving the reliability of the automatic feeding operation. If the suction cup-type automatic feeding device is not used, but another type of automatic feeding device, the very dry kelp is prone to breakage during transfer. Therefore, slightly moistening the kelp at the bend 204-2-1 prevents breakage during transfer. If no automatic feeding device is used, and the very dry kelp is manually picked up and transferred to complete the feeding operation, the very dry kelp is very easy to break during the picking and transfer process, causing damage. Therefore, at the bend 204-2-1, the kelp is moistened to a certain extent to increase the humidity, so that the very dry kelp is slightly wet, which can prevent the very dry kelp from breaking during the transfer process.

[0117] For the automatic unloading device 700, a robotic arm can be used to replace the lifting mechanism 702, the rotary cylinder 703, and the cylinder 706, and the suction cup connecting plate 704 can be fixed to the end of the robotic arm. The robotic arm moves to move the suction cup connecting plate 704.
