Description

Technical Field

[0001] The present invention relates to the technical field of kelp drying, and particularly to a double-line hanging conveyor device for kelp drying. Background Art

[0002] A kelp drying device is a piece of equipment used for drying kelp. It mainly dries kelp by means of a high-temperature air flow to remove moisture and extend the storage time. This device adopts an automated control system and has functions of temperature and humidity adjustment, and can efficiently and evenly complete the drying process of kelp.

[0003] However, the current kelp drying device has the following problems: Before drying kelp, the kelp drying device needs to perform saline spray cleaning on the kelp. Although saline spray can remove the sediment, impurities and attachments on the surface of the kelp, these impurities cannot be completely removed only by saline flushing. Therefore, we propose a double-line hanging conveyor device for kelp drying. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a double-line hanging conveyor device for kelp drying, which solves the problems raised in the above background art.

[0005] To achieve the above object, the present invention is implemented through the following technical solutions: A double-line hanging conveyor device for drying kelp, including a U-shaped drying line. Inside the U-shaped drying line, there is an annular hanging track. A number of hooks are evenly and equidistantly fixed at the mobile end of the annular hanging track. Inside the U-shaped drying line, there are two auxiliary cleaning devices. The auxiliary cleaning device includes two rotating rods and two notched cylinders. The two rotating rods are respectively rotatably installed on both sides inside the U-shaped drying line. At the top of the U-shaped drying line, there is a transmission box for controlling the rotation of the two rotating rods. The transmission box includes a fixed shell, a motor, and two gears. The fixed shell is fixed at the top of the U-shaped drying line. The two gears are respectively rotatably installed on both sides inside the fixed shell. The bottoms of the two gears are respectively fixedly connected to the tops of the two rotating rods. The motor is fixed on the top of the fixed shell, and the output end of the motor is fixedly connected to the top of one gear. Sponge rollers are fixedly installed on the outer parts of the two rotating rods. The two notched cylinders are respectively fixed on both sides inside the U-shaped drying line through brackets, and the notched cylinders are located in the feeding port direction of the U-shaped drying line. The outer wall of the notched cylinder is in contact with the outer wall of the sponge roller. A shaft rod is rotatably installed inside the notched cylinder through a bracket, and the shaft rod is connected to the rotating rod through a belt drive. A spiral blade is fixedly installed on the outer wall below the shaft rod. The output end of the motor drives the gear to rotate. One gear drives the other gear to rotate, so that the two gears drive the rotating rods to rotate. The rotating rods drive the sponge rollers to rotate. The sponge rollers rotate to roll and clean the surface of the kelp. At the same time, due to the contact between the notched cylinder and the outside of the sponge roller, impurities such as sediment, seaweed, and plankton adhered to the surface of the sponge roller will be scraped into the notched cylinder. When the rotating rod rotates, the rotating rod drives the shaft rod through the belt, and the shaft rod drives the spiral blade. The spiral blade pushes the impurities scraped into the notched cylinder downward.

[0006] According to the above technical solution, the U-shaped drying line is successively provided with a brine spray cleaning area, a double-sided high-pressure air knife drying area, a preheating and temperature-rising area, a balance dehumidification area, a temperature-rising drying area, and a temperature-lowering shaping area from the feed inlet to the discharge outlet. A U-shaped partition is fixed inside the U-shaped drying line, and the U-shaped partition is used to divide the internal space of the U-shaped drying line into upper and lower layers. The auxiliary cleaning device is located in the middle section of the brine spray cleaning area of the U-shaped drying line. The annular hanging track moves the kelp into the U-shaped drying line through a hook. The kelp will successively pass through the brine spray cleaning area, the double-sided high-pressure air knife drying area, the preheating and temperature-rising area, the balance dehumidification area, the temperature-rising drying area, and the temperature-lowering shaping area of the U-shaped drying line. The brine spray cleaning area will spray and clean the kelp with brine to remove the sediment and impurities on the surface. The double-sided high-pressure air knife drying area will use the high-pressure air knife to dry the kelp on both sides to remove the excess moisture and prepare for the subsequent drying process. The preheating and temperature-rising area will evaporate the moisture inside the kelp through preheating treatment to form a "sweating" phenomenon, which is beneficial to the subsequent drying process. The balance dehumidification area will carry out dehumidification treatment under constant temperature conditions, gradually discharge the moisture, form micro-channels, and further reduce the moisture content of the kelp. The temperature-rising drying area will gradually increase the temperature for drying until the predetermined moisture content is reached. The temperature-lowering shaping area will reduce the temperature to shape the dried kelp and maintain its shape and texture. Finally, the dried kelp will be exported and unloaded from the U-shaped drying line, and sorted and graded.

[0007] According to the above technical solution, the auxiliary cleaning device further includes two chute frames I, two L-shaped pressing plates, two L-shaped column rods, and two semi-circular blocks. Both of the two chute frames I are fixed to the bottom of the inner wall of the U-shaped drying line, and the two chute frames I are respectively located on the side of the two rotating rods away from the feed inlet of the U-shaped drying line. The two L-shaped pressing plates are respectively slidably installed inside the two chute frames I, and a spring is provided between the L-shaped pressing plate and the chute frame I. The L-shaped pressing plate is in contact with the outer wall of the sponge roller. The two semi-circular blocks are respectively fixed to the tops of the two L-shaped pressing plates. The two L-shaped column rods are respectively fixed to the outer walls above the two rotating rods. The side of the semi-circular block away from the rotating rod is semicircularly arranged. A cylinder is fixed to the end of the bottom of the L-shaped column rod away from the rotating rod. The semi-circular shape of the semi-circular block is located on the movement track of the cylinder of the L-shaped column rod. When the rotating rod rotates, the rotating rod drives the L-shaped column rod to rotate. The cylinder of the L-shaped column rod pushes the semi-circular shape of the semi-circular block to drive the L-shaped pressing plate to move along the inside of the chute frame I towards the sponge roller. The L-shaped pressing plate squeezes the sponge roller, and the water adsorbed by the sponge roller is extruded.

[0008] According to the above technical solution, two water removal devices are arranged at the rear section of the brine spray cleaning area of the U-shaped drying line. The water removal device includes two second chute frames and two elastic telescopic plates. Both of the two second chute frames are fixed at the bottom of the inner wall of the U-shaped drying line. The fixed ends of the two elastic telescopic plates are respectively slidably installed inside the two second chute frames, and a spring is arranged between the fixed end of the elastic telescopic plate and the second chute frame. Clamping plates are respectively fixed on one sides of the telescopic ends of the two elastic telescopic plates close to each other. L-shaped sliding plates are respectively installed transversely and slidably on the tops of the two second chute frames. The side of the L-shaped sliding plate away from the second chute frame is slidably connected to the outer wall of the clamping plate. Hinge rods are respectively hinged on the tops of the two L-shaped sliding plates. One ends of the hinge rods away from the L-shaped sliding plates are hinged on the outer wall of the L-shaped pressing plate. A number of inclined tubes are evenly and equidistantly fixed on one sides of the two clamping plates away from each other. Both of the two clamping plates are arranged in a wavy shape. The wave convex surface of one clamping plate is arranged opposite to the wave concave surface of the other clamping plate. A number of the inclined tubes are all located below the convex surfaces on one sides of the clamping plates away from each other. Through holes communicating with the inside of the inclined tubes are respectively opened on one sides of the two clamping plates close to each other. During the process of the L-shaped pressing plate moving along the inside of the first chute frame towards the sponge roller, the L-shaped pressing plate pulls the hinge rod to drive the L-shaped sliding plate to move along the top of the second chute frame in a direction away from the second chute frame. The L-shaped sliding plate pushes the clamping plate to move accordingly, and the clamping plate drives the telescopic end of the elastic telescopic plate to stretch, so that the two clamping plates approach each other. The two clamping plates squeeze the kelp conveyed by the hook. With the wavy clamping plate design, when the two clamping plates are closed, the convex and concave surfaces of the wavy clamping plate can wrap the surface of the kelp more evenly. It should be noted that after the two clamping plates clamp the kelp and the hook drives the kelp to move, the kelp will drive the clamping plate and the elastic telescopic plate to move along the second chute frame in a direction away from the L-shaped pressing plate.

[0009] The present invention provides a double-line hanging conveying device for drying kelp. It has the following beneficial effects:

[0010] (1) Through the setting of the auxiliary cleaning device, the present invention enables the motor, gear, and rotating rod to cooperate to drive the sponge roller to rotate and roll-press and clean the surface of kelp. The sponge roller can effectively remove impurities such as sediment, seaweed, and plankton on the surface of kelp, ensuring the cleanliness of the kelp surface. Moreover, the rolling pressure of the sponge roller can help the brine penetrate better into the surface of kelp, thereby improving the efficiency of brine spray cleaning, avoiding the waste of brine, reducing costs. At the same time, due to the external contact between the notched cylinder and the sponge roller, impurities such as sediment, seaweed, and plankton adhered to the surface of the sponge roller will be scraped into the notched cylinder, thus transferring the impurities from the surface of the sponge roller to the notched cylinder, effectively reducing the secondary pollution of impurities and preventing the impurities from flowing back to other kelps. At the same time, the rotating rod and the shaft rod cooperate to drive the spiral blade to push the impurities scraped into the notched cylinder downward, further avoiding the impurities flowing back to the surface of the kelp again, thus preventing the decline of the cleaning effect of the sponge roller or the secondary pollution of other kelps; at the same time, the rotating rod, L-shaped column rod, semi-circular block, L-shaped pressing plate, and the first chute frame cooperate to drive the L-shaped pressing plate to squeeze the sponge roller, and the water adsorbed by the sponge roller is squeezed out. During the squeezing process, the water squeezed out from the surface of the sponge roller will take away impurities such as sediment, seaweed, and plankton attached to the surface of the kelp, and the impurities carried away by the water flow can be effectively separated from the surface of the kelp, reducing the residue of impurities, thereby improving the cleanliness of the sponge roller for kelp.

[0011] (2) Through the setting of the U-shaped drying line and the hanging hook, the present invention enables the kelp to sequentially pass through the brine spray cleaning area, double-sided high-pressure air knife drying area, preheating and temperature-rising area, balance dehumidification area, temperature-rising drying area, and temperature-lowering shaping area of the U-shaped drying line. The brine spray cleaning area will spray and clean the kelp with brine to remove sediment and impurities on the surface. The double-sided high-pressure air knife drying area will use high-pressure air knives to dry the kelp on both sides to remove excess water, preparing for the subsequent drying process. The preheating and temperature-rising area makes the water inside the kelp evaporate through preheating treatment, forming a "sweating" phenomenon, which is beneficial to the subsequent drying process. The balance dehumidification area conducts dehumidification treatment under constant temperature conditions, gradually discharging moisture to form micro-channels, further reducing the moisture content of the kelp. In the temperature-rising drying area, the temperature is gradually increased for drying until the predetermined moisture content is reached. In the temperature-lowering shaping area, the temperature is reduced to shape the dried kelp and maintain its shape and texture. Finally, the dried kelp is exported and unloaded from the U-shaped drying line, and sorted and graded; the U-shaped partition divides the internal space of the U-shaped drying line into upper and lower layers, enabling two independent drying lines to be formed inside the U-shaped drying line. Each line uses a circular hanging track to hang and transport the kelp, facilitating the uniform suspension and movement of the kelp and uniform heating. Both the upper and lower layers of the U-shaped drying line can be used for drying kelp, improving the space utilization rate, and an appropriate distance is reserved between each hanging hook so that the subsequent hot air can uniformly penetrate and dry the kelp.

[0012] (3) Through the setting of the water removal device, the L-shaped pressing plate, the first chute frame, the sponge roller, the hinge rod, the L-shaped sliding plate, and the second chute frame cooperate to drive the two clamping plates to squeeze the kelp conveyed by the hook. Through the squeezing action of the clamping plates, the removal of moisture on the surface of the kelp can be accelerated, which helps to reduce the moisture remaining on the surface of the kelp, reduce the impact of moisture on the kelp, and lay a foundation for the subsequent drying process. Moreover, with the wavy clamping plate design, when the two clamping plates are closed, the convex and concave surfaces of the wavy clamping plate can more evenly wrap the surface of the kelp, so that the moisture attached to the surface of the kelp can be more effectively squeezed out from the sponge roller. And during this process, the inclined tube will divert the water on the surface of the kelp outward. Through the diversion function of the inclined tube, the water is effectively guided to the outside instead of flowing down along the surface of the kelp. This helps to improve the efficiency of moisture removal. The moisture on the surface of the kelp will be discharged in time during the squeezing process of the clamping plates, avoiding excessive moisture staying on the surface of the kelp and causing subsequent moisture retention. At the same time, after the two clamping plates clamp the kelp, when the hook drives the kelp to move, the kelp will drive the clamping plates and the elastic telescopic plate to move along the second chute frame in a direction away from the L-shaped pressing plate, thus avoiding the problem that the clamping plates damage the kelp when the hook continues to drive the kelp to move after the two clamping plates clamp the kelp.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Please refer to Figure 1 - Figure 8, an embodiment of the present invention is: a double - line hanging conveyor device for drying kelp, including a U - shaped drying line 1. Inside the U - shaped drying line 1, there is an annular hanging track 2. A number of hooks 3 are evenly and equidistantly fixed at the mobile end of the annular hanging track 2. Inside the U - shaped drying line 1, there are two auxiliary cleaning devices 4. The auxiliary cleaning device 4 includes two rotating rods 41 and two notched cylinders 46. The two rotating rods 41 are respectively rotatably installed on both sides inside the U - shaped drying line 1. At the top of the U - shaped drying line 1, there is a transmission box 42 for controlling the rotation of the two rotating rods 41. The transmission box 42 includes a fixed shell 421, a motor 422, and two gears 423. The fixed shell 421 is fixed at the top of the U - shaped drying line 1. The two gears 423 are respectively rotatably installed on both sides inside the fixed shell 421. The bottoms of the two gears 423 are respectively fixedly connected to the tops of the two rotating rods 41. The motor 422 is fixed at the top of the fixed shell 421, and the output end of the motor 422 is fixedly connected to the top of one of the gears 423. Sponge rollers 43 are fixedly installed on the outer parts of the two rotating rods 41. The two notched cylinders 46 are respectively fixed on both sides inside the U - shaped drying line 1 through brackets, and the notched cylinders 46 are located in the feeding direction of the U - shaped drying line 1. The outer walls of the notched cylinders 46 are in contact with the outer walls of the sponge rollers 43. Inside the notched cylinders 46, a shaft rod 44 is rotatably installed through a bracket. The shaft rod 44 is connected to the rotating rod 41 through a belt drive. A spiral blade 45 is fixedly installed on the outer wall below the shaft rod 44. Through the above - mentioned structural arrangement, the sponge rollers 43 rotate to roll - press and clean the surface of the kelp. The sponge rollers 43 can effectively remove impurities such as sediment, seaweed, and plankton on the surface of the kelp, ensuring the cleanliness of the kelp surface. Moreover, the rolling - press effect of the sponge rollers 43 can help the brine penetrate better into the surface of the kelp, thereby improving the efficiency of brine spray cleaning, avoiding the waste of brine, and reducing costs. At the same time, through the above - mentioned structural arrangement, the impurities such as sediment, seaweed, and plankton adhered to the surface of the sponge rollers 43 will be scraped into the notched cylinders 46, thus transferring the impurities from the surface of the sponge rollers 43 to the notched cylinders 46, effectively reducing the secondary pollution of the impurities, preventing the impurities from flowing back to other kelps. And the rotating rod 41 drives the shaft rod 44 to rotate through a belt, the shaft rod 44 drives the spiral blade 45, and the spiral blade 45 pushes the impurities scraped into the notched cylinders 46 downward, further avoiding the impurities flowing back to the surface of the kelp again, thereby preventing the decline of the cleaning effect of the sponge rollers 43 or the secondary pollution of other kelps.

[0024] The U-shaped drying line 1 is sequentially provided with a brine spray cleaning area, a double-sided high-pressure air knife drying area, a preheating and temperature-rising area, a balance dehumidification area, a temperature-rising drying area, and a temperature-reducing shaping area from the feed inlet to the discharge outlet. A U-shaped partition is fixed inside the U-shaped drying line 1, and the U-shaped partition is used to divide the internal space of the U-shaped drying line 1 into upper and lower layers. Two auxiliary cleaning devices 4 are located in the middle of the brine spray cleaning area of the U-shaped drying line 1. The annular hanging track 2 moves the kelp into the U-shaped drying line 1 through the hook 3. The kelp will sequentially pass through the brine spray cleaning area, the double-sided high-pressure air knife drying area, the preheating and temperature-rising area, the balance dehumidification area, the temperature-rising drying area, and the temperature-reducing shaping area of the U-shaped drying line 1. The brine spray cleaning area will spray and clean the kelp with brine to remove the sediment and impurities on the surface. The double-sided high-pressure air knife drying area will use the high-pressure air knife to dry the kelp on both sides to remove the excess moisture and prepare for the subsequent drying process. The preheating and temperature-rising area makes the moisture inside the kelp evaporate through preheating treatment to form a "sweating" phenomenon, which is beneficial to the subsequent drying process. The balance dehumidification area performs dehumidification treatment under constant temperature conditions, gradually discharges moisture, forms micro-channels, and further reduces the moisture content of the kelp. The temperature-rising drying area gradually raises the temperature for drying until the predetermined moisture content is reached. The temperature-reducing shaping area reduces the temperature to shape the dried kelp and maintain its shape and texture. Finally, the dried kelp is exported and unloaded from the U-shaped drying line 1, and then sorted and graded.

[0025] The auxiliary cleaning device 4 further includes two first chute frames 47, two L-shaped pressing plates 48, two L-shaped column rods 49, and two semi-circular blocks 410. The two first chute frames 47 are both fixed to the bottom of the inner wall of the U-shaped drying line 1. The two first chute frames 47 are respectively located on one side of the two rotating rods 41 away from the feed inlet of the U-shaped drying line 1. The two L-shaped pressing plates 48 are respectively slidably installed inside the two first chute frames 47, and a spring is provided between the L-shaped pressing plate 48 and the first chute frame 47. The L-shaped pressing plate 48 is in contact with the outer wall of the sponge roller 43. The two semi-circular blocks 410 are respectively fixed to the tops of the two L-shaped pressing plates 48. The two L-shaped column rods 49 are respectively fixed to the outer walls above the two rotating rods 41. The side of the semi-circular block 410 away from the rotating rod 41 is semi-circularly arranged. A cylinder is fixed to the end of the bottom of the L-shaped column rod 49 away from the rotating rod 41. The semi-circular shape of the semi-circular block 410 is located on the movement track of the cylinder of the L-shaped column rod 49. Through the setting of the above structure, the L-shaped pressing plate 48 squeezes the sponge roller 43, and the moisture adsorbed by the sponge roller 43 is squeezed out. During the squeezing process, the water squeezed out from the surface of the sponge roller 43 will take away the sediment, seaweed, plankton and other impurities attached to the surface of the kelp. The impurities carried away by the water flow can be effectively separated from the surface of the kelp, reducing the residue of impurities, thereby improving the cleaning degree of the sponge roller 43 for the kelp.

[0026] During use, hang the kelp to be dried on the hook 3, start the circular hanging track 2, and the circular hanging track 2 will move the kelp into the U-shaped drying line 1 through the hook 3. The kelp will successively pass through the brine spray cleaning area, double-sided high-pressure air knife drying area, preheating and warming area, balance dehumidification area, warming and drying area, and cooling and shaping area of the U-shaped drying line 1. The brine spray cleaning area will spray and clean the kelp with brine to remove the sediment and impurities on the surface. The double-sided high-pressure air knife drying area will use the high-pressure air knife to dry the kelp on both sides to remove the excess moisture and prepare for the subsequent drying process. The preheating and warming area will evaporate the moisture inside the kelp through preheating treatment to form a "sweating" phenomenon, which is beneficial to the subsequent drying process. The balance dehumidification area will carry out dehumidification treatment under constant temperature conditions, gradually discharge the moisture, form micro-channels, and further reduce the moisture content of the kelp. In the warming and drying area, the temperature will be gradually increased for drying until the predetermined moisture content is reached. In the cooling and shaping area, the temperature will be reduced to shape the dried kelp and maintain its shape and texture. Finally, the dried kelp will be exported and unloaded from the U-shaped drying line 1, and then sorted and graded.

[0027] It should be noted that the internal tunnel of the U-shaped drying line 1 is divided into multiple temperature zones, and different temperatures can be set for each temperature zone according to the drying requirements of the kelp. Preheating and warming area (zone 1): temperature 50 - 55 °C, the central temperature of the kelp is 50 °C, and the humidity in the box is relatively high. The main purpose is to keep the internal and external temperatures of the kelp consistent to prevent the formation of a dense film on the surface and facilitate the subsequent moisture discharge. Balance dehumidification area (zone 2): temperature 55 - 60 °C, adjust the air valve to control the wind speed, use weak wind for dehumidification, keep the humidity in the box low, and gradually discharge the moisture to form micro-channels; Warming and drying area (zone 3): temperature 65 - 70 °C, adjust the air valve to control the wind speed, use strong wind for moisture discharge and drying, realize waste heat recovery and enter the waste heat warming of zone 1 for recycling. Cooling and shaping area (zone 4): temperature 50 - 55 °C, adjust the air valve to control the wind speed, cool and shape, and avoid deformation due to excessive dehydration.

[0028] It should also be noted that the U-shaped partition divides the internal space of the U-shaped drying line 1 into upper and lower layers, making two independent drying lines inside the U-shaped drying line 1. Each line uses the circular hanging track 2 to hang and transport the kelp, which is convenient for the uniform suspension and movement of the kelp and uniform heating. Both the upper and lower layers of the U-shaped drying line 1 can be used for drying the kelp, improving the space utilization rate, and an appropriate distance is reserved between each hook 3 so that the subsequent hot air can evenly penetrate and dry the kelp.

[0029] When the annular hanging track 2 moves kelp into the brine spray cleaning area of the U-shaped drying line 1 through the hook 3, the kelp will pass between two sponge rollers 43. Start the motor 422, and the output end of the motor 422 drives the gear 423 to rotate. One gear 423 drives the other gear 423 to rotate, so that the two gears 423 drive the rotating rod 41 to rotate. The rotating rod 41 drives the sponge roller 43 to rotate, and the rotating sponge roller 43 rolls and cleans the surface of the kelp. The sponge roller 43 can effectively remove impurities such as sediment, seaweed, and plankton on the surface of the kelp, ensuring the cleanliness of the kelp surface. Moreover, the rolling effect of the sponge roller 43 can help the brine better penetrate the surface of the kelp, thereby improving the efficiency of brine spray cleaning, avoiding the waste of brine, reducing costs. At the same time, since the notch cylinder 46 is in external contact with the sponge roller 43, impurities such as sediment, seaweed, and plankton adhered to the surface of the sponge roller 43 will be scraped into the notch cylinder 46, thus transferring the impurities from the surface of the sponge roller 43 to the notch cylinder 46, effectively reducing the secondary pollution of impurities and preventing the impurities from flowing back to other kelps. When the rotating rod 41 rotates, the rotating rod 41 drives the shaft rod 44 to rotate through the belt, and the shaft rod 44 drives the spiral blade 45. The spiral blade 45 pushes the impurities scraped into the notch cylinder 46 downward, further avoiding the impurities flowing back to the surface of the kelp again, thereby preventing the decline of the cleaning effect of the sponge roller 43 or the secondary pollution of other kelps; when the rotating rod 41 rotates, the rotating rod 41 drives the L-shaped column rod 49 to rotate. The cylinder of the L-shaped column rod 49 pushes the semi-circular shape of the semi-circular block 410 to drive the L-shaped pressing plate 48 to move along the inside of the chute frame 47 towards the sponge roller 43. The L-shaped pressing plate 48 squeezes the sponge roller 43, and the water adsorbed by the sponge roller 43 is squeezed out. During the squeezing process, the water squeezed out from the surface of the sponge roller 43 will carry away impurities such as sediment, seaweed, and plankton attached to the surface of the kelp. The impurities carried away by the water flow can be effectively separated from the surface of the kelp, reducing the residue of impurities, thereby improving the cleanliness of the sponge roller 43 for the kelp.

[0030] Please refer to Figure 1 - Figure 8, on the basis of the above embodiments, in another embodiment of the present invention, two water removal devices 5 are provided at the rear section of the brine spray cleaning area of the U-shaped drying line 1. The water removal device 5 includes two second chute frames 51 and two elastic telescopic plates 55. Both of the two second chute frames 51 are fixed to the bottom of the inner wall of the U-shaped drying line 1. The fixed ends of the two elastic telescopic plates 55 are respectively slidably installed inside the two second chute frames 51, and a spring is provided between the fixed end of the elastic telescopic plate 55 and the second chute frame 51. On the side where the telescopic ends of the two elastic telescopic plates 55 are close to each other, clamping plates 52 are fixed. On the top of both of the two second chute frames 51, L-shaped sliding plates 54 are transversely slidably installed. The side of the L-shaped sliding plate 54 away from the second chute frame 51 is slidably connected to the outer wall of the clamping plate 52. On the top of both of the two L-shaped sliding plates 54, hinge rods 53 are hinged. The end of the hinge rod 53 away from the L-shaped sliding plate 54 is hinged to the outer wall of the L-shaped pressing plate 48. On the side where the two clamping plates 52 are away from each other, a number of inclined tubes 56 are evenly and equidistantly fixed. Both of the two clamping plates 52 are arranged in a wavy shape. The wavy convex surface of one clamping plate 52 is arranged opposite to the wavy concave surface of the other clamping plate 52. A number of inclined tubes 56 are all located below the convex surface on the side where the two clamping plates 52 are away from each other. On the side where the two clamping plates 52 are close to each other, through holes communicating with the inside of the inclined tubes 56 are opened. Through the setting of the above structure, the two clamping plates 52 squeeze the kelp conveyed by the hanging hook 3. Through the squeezing action of the clamping plates 52, the exclusion of water on the surface of the kelp can be accelerated, which helps to reduce the water retained on the surface of the kelp, reduce the influence of water on the kelp, and lay a foundation for the subsequent drying process. Moreover, with the design of the wavy clamping plates 52, when the two clamping plates 52 are closed, the convex and concave surfaces of the wavy clamping plates 52 can wrap the surface of the kelp more evenly, so that the water attached to the surface of the kelp can be more effectively squeezed out from the sponge roller 43. And during this process, the inclined tubes 56 will divert the water on the surface of the kelp outward. Through the diversion action of the inclined tubes 56, the water is effectively guided to the outside instead of flowing down along the surface of the kelp. This helps to improve the efficiency of water removal. The water on the surface of the kelp will be discharged in time during the squeezing process of the clamping plates 52, avoiding excessive water staying on the surface of the kelp and causing subsequent water retention. At the same time, through the setting of the above structure, when the hanging hook 3 drives the kelp to move, the kelp will drive the clamping plates 52 and the elastic telescopic plates 55 to move along the second chute frame 51 in a direction away from the L-shaped pressing plate 48, thus avoiding the problem that when the hanging hook 3 continues to drive the kelp to move after the two clamping plates 52 clamp the kelp, the clamping plates 52 will damage the kelp.

[0031] During use, when the L-shaped pressing plate 48 moves along the inside of the chute frame 1 towards the sponge roller 43, the L-shaped pressing plate 48 pulls the articulated rod 53 to drive the L-shaped sliding plate 54 to move along the top of the chute frame 2 away from the chute frame 2. The L-shaped sliding plate 54 pushes the clamping plate 52 to move accordingly, and the clamping plate 52 drives the telescopic end of the elastic telescopic plate 55 to stretch, so that the two clamping plates 52 approach each other. The two clamping plates 52 squeeze the kelp conveyed by the hook 3. Through the squeezing action of the clamping plates 52, the exclusion of water on the surface of the kelp can be accelerated, which helps to reduce the water retained on the surface of the kelp, reduce the influence of water on the kelp, and lay a foundation for the subsequent drying process. Moreover, due to the wavy design of the clamping plates 52, when the two clamping plates 52 are closed, the convex and concave surfaces of the wavy clamping plates 52 can wrap the surface of the kelp more evenly, so that the water attached to the surface of the kelp can be more effectively squeezed out from the sponge roller 43. And during this process, the inclined pipe 56 will divert the water on the surface of the kelp outwards. Through the diversion effect of the inclined pipe 56, the water is effectively guided to the outside instead of flowing down along the surface of the kelp. This helps to improve the efficiency of water removal. The water on the surface of the kelp will be discharged in time during the squeezing process of the clamping plates 52, avoiding excessive water staying on the surface of the kelp and causing subsequent water retention.

[0032] It should be noted that after the two clamping plates 52 clamp the kelp, when the hook 3 drives the kelp to move, the kelp will drive the clamping plates 52 and the elastic telescopic plate 55 to move along the chute frame 2 away from the L-shaped pressing plate 48, thus avoiding the problem that when the hook 3 continues to drive the kelp to move after the two clamping plates 52 clamp the kelp, the clamping plates 52 will damage the kelp.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
