Description

Technical Field

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

[0002] The kelp drying device is a device used for drying kelp. It uses high-temperature airflow to dry the kelp, removing moisture and extending its shelf life. The device utilizes an automated control system with temperature and humidity regulation, enabling efficient and uniform drying of the kelp.

[0003] However, the current kelp drying device has the following problems: the kelp needs to be sprayed with salt water before drying. Although salt water spraying can remove mud, impurities and attachments on the surface of the kelp, these impurities cannot be completely removed by salt water flushing alone. Therefore, we propose a double-line hanging conveyor device for kelp drying. Summary of the Invention

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

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a double-line hanging conveyor for drying kelp, comprising a U-shaped drying line, a circular hanging track is arranged inside the U-shaped drying line, a number of hooks are evenly and equidistantly fixed on the moving end of the circular hanging track, two auxiliary cleaning devices are arranged inside the U-shaped drying line, the auxiliary cleaning device comprises two rotating rods and two notched cylinders, the two rotating rods are rotatably installed on both sides of the interior of the U-shaped drying line, a transmission box for controlling the rotation of the two rotating rods is provided on the top of the U-shaped drying line, the transmission box comprises a fixed shell, a motor, and two gears, the fixed shell is fixed on the top of the U-shaped drying line, the two gears are rotatably installed on both sides of the interior of the fixed shell, the bottoms of the two gears are fixedly connected to the tops of the two rotating rods respectively, the motor is fixed on the top of the fixed shell, and the output end of the motor is connected to the top of a gear. The two gears are fixedly connected, and sponge rollers are fixed on the outside of the two rotating rods. The two notched cylinders are respectively fixed on both sides of the inside of the U-shaped drying line through brackets, and the notched cylinder is located in the feed inlet direction of the U-shaped drying line. The notched cylinder is in contact with the outer wall of the sponge roller, and the inside of the notched cylinder is rotatably installed with an axle rod, and the axle rod and the rotating rod are connected by a belt drive. A spiral blade is fixed at the outer wall below the axle rod, and the output end of the motor drives the gear to rotate, and one gear drives the other gear to rotate, so that the two gears drive the rotating rod to rotate, and the rotating rod drives the sponge roller to rotate, and the sponge roller rotates to roll and clean the surface of the kelp. At the same time, due to the external contact between the notched cylinder and the sponge roller, impurities such as mud, 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 axle rod through the belt, and the axle rod drives the spiral blade, and 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 provided with a salt water spray cleaning area, a double-sided high-pressure air knife drying area, a preheating and heating area, a balanced dehumidification area, a heating and drying area, and a cooling and shaping area in sequence from the feed port to the discharge port. 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 two layers, and the auxiliary cleaning device is located in the middle section of the salt water spray cleaning area of the U-shaped drying line. The annular hanging track moves the kelp into the U-shaped drying line through the hook. The kelp will pass through the salt water spray cleaning area, the double-sided high-pressure air knife drying area, the preheating and heating area, the balanced dehumidification area, the heating and drying area, and the cooling and shaping area of the U-shaped drying line in sequence. The salt water spray cleaning area will use salt water to spray and clean the kelp. The kelp is washed to remove the mud and impurities on the surface. The double-sided high-pressure air knife drying area uses high-pressure air knives to dry the kelp on both sides to remove excess moisture and prepare for the subsequent drying process. The preheating and heating area uses preheating treatment to evaporate the moisture inside the kelp, forming a "sweating" phenomenon, which is beneficial to the subsequent drying process. The balanced dehumidification area performs dehumidification treatment under constant temperature conditions, gradually removes moisture, forms tiny channels, and further reduces the moisture content of the kelp. The heating and drying area gradually increases the temperature for drying until the predetermined moisture content is reached. The cooling and shaping area reduces the temperature to shape the dried kelp to maintain its shape and texture. Finally, the dried kelp is unloaded from the U-shaped drying line and sorted and graded.

[0007] The L-shaped rollers are connected to the rollers to form a U-shaped roller, and the L-shaped rollers are connected to the rollers to form a U-shaped roller. The top of the L-shaped column is fixed to the upper outer wall of the two rotating rods respectively, and the semicircular block is set in a semicircular shape on the side away from the rotating rod. The bottom of the L-shaped column is fixed with a cylinder at one end away from the rotating rod, and the semicircular shape of the semicircular block is located on the cylindrical motion trajectory of the L-shaped column. When the rotating rod rotates, the rotating rod drives the L-shaped column to rotate, and the cylinder of the L-shaped column pushes the semicircular shape of the semicircular block to drive the L-shaped pressure plate to move along the inside of the slide frame toward the sponge roller. The L-shaped pressure plate squeezes the sponge roller, and the moisture adsorbed by the sponge roller is squeezed out.

[0008] The cam is fixed to the bottom of the inner wall of the U-shaped drying line, and the fixed ends of the two elastic telescopic plates are slidably mounted on the inside of the two chute frames, and a spring is provided between the fixed ends of the elastic telescopic plates and the chute frames, and the two elastic telescopic plates are fixed on the side where the telescopic ends of the two elastic telescopic plates are close to each other, and a clamping plate is fixed on the top of the two chute frames. The L-shaped slides are slidably mounted on the tops of the two chute frames, and the side of the L-shaped slides away from the chute frame is slidably connected to the outer wall of the clamping plate. The tops of the two L-shaped slides are hinged with a hinge rod, and one end of the hinge rod away from the L-shaped slide is hinged at the outer wall of the L-shaped pressure plate. A number of inclined tubes are evenly and equidistantly fixed on the side where the two clamps are away from each other. The two clamps are wavy, and the clamping plate on one side The L-shaped slide plate is moved along the second end of the slide frame to move in the direction of the L-shaped pressure plate, and the L-shaped slide plate pushes the splint to move along the second end of the slide frame, and the splint drives the elastic expansion plate to stretch, so that the two splints are close to each other, and the two splints squeeze the kelp transmitted by the hook, and the wavy splint design, when the two splints are closed, the convex and concave surfaces of the wavy splint can more evenly wrap the surface of the kelp. It should be noted that after the two splints clamp the kelp, the hook drives the kelp to move, and the kelp will carry the splint and the elastic expansion plate along the second slide frame to move away from the L-shaped pressure plate.

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

[0010] (1) The present invention sets up an auxiliary cleaning device, so that the motor, gears and rotating rod cooperate to drive the sponge roller to rotate and perform roller cleaning on the surface of the kelp. The sponge roller can effectively remove impurities such as mud, seaweed and plankton on the surface of the kelp, ensuring the cleanliness of the kelp surface. The rolling action of the sponge roller can help the salt water to better penetrate into the surface of the kelp, thereby improving the efficiency of salt water spray cleaning, avoiding the waste of salt water and reducing costs. At the same time, due to the contact between the notch cylinder and the outside of the sponge roller, the mud, seaweed and plankton adhering to the surface of the sponge roller will be scraped into the notch cylinder, thereby transferring the impurities from the surface of the sponge roller to the notch cylinder, effectively reducing the secondary pollution of impurities and preventing The impurities flow back to other kelp, and 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, thereby further preventing the impurities from flowing back to the surface of the kelp again, thereby preventing the cleaning effect of the sponge roller from declining or other kelp from being contaminated for the second time; at the same time, the rotating rod, L-shaped column rod, semicircular block, L-shaped pressure plate, and slide frame cooperate to drive the L-shaped pressure 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 mud, 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 residual impurities, thereby improving the cleanliness of the sponge roller for the kelp.

[0011] (2) The present invention sets up a U-shaped drying line and a hook, so that the kelp will pass through the salt water spray cleaning area, double-sided high-pressure air knife drying area, preheating and heating area, balanced dehumidification area, heating and drying area, and cooling and shaping area of the U-shaped drying line in sequence. The salt water spray cleaning area will use salt water to spray and clean the kelp to remove the mud 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 moisture and prepare for the subsequent drying process. The preheating and heating area evaporates the moisture inside the kelp through preheating treatment, forming a "sweating" phenomenon, which is beneficial to the subsequent drying process. The balanced dehumidification area performs dehumidification treatment under constant temperature conditions, gradually removes moisture, forms micro channels, and further reduces the kelp. The moisture content of the kelp is determined by heating the drying zone, gradually increasing the temperature for drying until the predetermined moisture content is reached, cooling the shaping zone, reducing the temperature to shape the dried kelp to maintain its shape and texture, and finally the dried kelp is unloaded from the U-shaped drying line for sorting and grading; the U-shaped partition divides the internal space of the U-shaped drying line into two layers, so that two independent drying lines are formed inside the U-shaped drying line. Each line uses a circular hanging track to hang and transport the kelp, which is convenient for the uniform hanging 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 the kelp, which improves the space utilization rate, and an appropriate distance is reserved between each hook so that the subsequent hot air can penetrate and dry the kelp evenly.

[0012] (3) The present invention sets up a water removal device, so that the L-shaped pressing plate, the first chute frame, the sponge roller, the hinged rod, the L-shaped slide plate, and the second chute frame cooperate to drive the two clamps to squeeze the kelp transmitted by the hook. The squeezing action of the clamps can accelerate the removal of water on the surface of the kelp, help reduce the water retained on the surface of the kelp, reduce the impact of water on the kelp, and lay the foundation for the subsequent drying process. In addition, the wavy clamp design, when the two clamps are closed, the convex and concave surfaces of the wavy clamps can more evenly wrap the surface of the kelp, so that the water attached to the surface of the kelp can be squeezed out from the sponge roller more effectively, and in this process, the slanted The tube will divert the water on the surface of the kelp outward. Through the diversion effect of the inclined tube, the water is effectively guided to the outside instead of flowing down along the surface of the kelp, which 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 plywood, avoiding excessive water staying on the surface of the kelp and causing subsequent water retention; at the same time, after the two plywood clamps the kelp, the hook drives the kelp to move, and the kelp will move along the slide frame in the direction away from the L-shaped pressure plate with the plywood and the elastic expansion plate, thereby avoiding the problem that the plywood will damage the kelp when the hook continues to drive the kelp to move after the two plywood clamps the kelp.

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

[0023] See also Figure 1 - Figure 8One embodiment of the present invention is: a double-line hanging conveyor for drying kelp, comprising a U-shaped drying line 1, an annular hanging track 2 is provided inside the U-shaped drying line 1, a plurality of hooks 3 are fixed evenly and equidistantly at the moving end of the annular hanging track 2, two auxiliary cleaning devices 4 are provided inside the U-shaped drying line 1, the auxiliary cleaning device 4 comprises two rotating rods 41 and two notched cylinders 46, the two rotating rods 41 are rotatably mounted on both sides of the interior of the U-shaped drying line 1, a transmission box 42 for controlling the rotation of the two rotating rods 41 is provided on the top of the U-shaped drying line 1, the transmission box 42 comprises a fixed shell 421, a motor 4 22. Two gears 423, a fixed shell 421 is fixed to the top of the U-shaped drying line 1, and the two gears 423 are rotatably mounted on both sides of the interior of the fixed shell 421. The bottoms of the two gears 423 are fixedly connected to the tops of the two rotating rods 41. The motor 422 is fixed to the top of the fixed shell 421, and the output end of the motor 422 is fixedly connected to the top of one gear 423. Sponge rollers 43 are fixed to the outside of the two rotating rods 41. Two notched cylinders 46 are fixed to both sides of the interior of the U-shaped drying line 1 through brackets, and the notched cylinder 46 is located in the feed direction of the U-shaped drying line 1. The notched cylinder 46 The notched cylinder 46 is in contact with the outer wall of the sponge roller 43. A shaft 44 is rotatably mounted inside the notched cylinder 46 through a bracket. The shaft 44 is connected to the rotating rod 41 through a belt drive. A spiral blade 45 is fixed to the outer wall below the shaft 44. Through the arrangement of the above structure, the sponge roller 43 is rotated to roll and clean the surface of the kelp. The sponge roller 43 can effectively remove impurities such as mud, seaweed, and plankton on the surface of the kelp to ensure that the surface of the kelp is clean. In addition, the rolling action of the sponge roller 43 can help the salt water to better penetrate the surface of the kelp, thereby improving the efficiency of the salt water spray cleaning, avoiding the waste of salt water, and reducing costs. At the same time, through the arrangement of the above-mentioned structure, impurities such as mud, seaweed, and plankton adhered to the surface of the sponge roller 43 will be scraped into the notched tube 46, thereby transferring the impurities from the surface of the sponge roller 43 to the notched tube 46, effectively reducing the secondary pollution of impurities and preventing impurities from flowing back to other kelp. The rotating rod 41 drives the shaft 44 to rotate through the belt, and the shaft 44 drives the spiral blades 45. The spiral blades 45 push the impurities scraped into the notched tube 46 downward, thereby further avoiding the impurities from flowing back to the surface of the kelp again, thereby preventing the cleaning effect of the sponge roller 43 from decreasing or other kelp from being contaminated for the second time.

[0024] The U-shaped drying line 1 is provided with a salt water spray cleaning area, a double-sided high-pressure air knife drying area, a preheating and heating area, a balanced dehumidification area, a heating and drying area, and a cooling and shaping area in sequence from the feed port to the discharge port. A U-shaped partition is fixed inside the U-shaped drying line 1. The U-shaped partition is used to divide the internal space of the U-shaped drying line 1 into two layers, an upper layer and an lower layer. Two auxiliary cleaning devices 4 are located in the middle section of the salt water 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 with the hook 3. The kelp will pass through the salt water spray cleaning area, the double-sided high-pressure air knife drying area, the preheating and heating area, the balanced dehumidification area, the heating and drying area, and the cooling and shaping area of the U-shaped drying line 1 in sequence. The salt water spray cleaning area will spray the kelp with salt water to remove 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 moisture and prepare for the subsequent drying process. The preheating and heating area will evaporate the moisture inside the kelp through preheating treatment, forming a "sweating" phenomenon, which is beneficial to the subsequent drying process. The balanced dehumidification area will perform dehumidification treatment under constant temperature conditions, gradually remove moisture, form tiny channels, and further reduce the moisture content of the kelp. The heating and drying area will gradually increase the temperature for drying until the predetermined moisture content is reached. The cooling and shaping area will reduce the temperature to shape the dried kelp to maintain its shape and texture. Finally, the dried kelp will be unloaded from the U-shaped drying line 1 and sorted and graded.

[0025] The auxiliary cleaning device 4 also includes two chute racks 47, two L-shaped pressure plates 48, two L-shaped pillars 49, and two semicircular blocks 410. The two chute racks 47 are fixed to the bottom of the inner wall of the U-shaped drying line 1. The two chute racks 47 are respectively located on the side of the two rotating rods 41 away from the feeding port of the U-shaped drying line 1. The two L-shaped pressure plates 48 are respectively slidably installed inside the two chute racks 47, and a spring is provided between the L-shaped pressure plate 48 and the chute rack 47. The L-shaped pressure plate 48 contacts the outer wall of the sponge roller 43. The two semicircular blocks 410 are respectively fixed to the top of the two L-shaped pressure plates 48, and the two L-shaped pillars 49 are respectively fixed to the two rotating rods 4 1, a semicircular block 410 is arranged in a semicircular shape on the side away from the rotating rod 41, and a cylinder is fixed to the end of the bottom of the L-shaped column 49 away from the rotating rod 41. The semicircular shape of the semicircular block 410 is located on the cylindrical movement trajectory of the L-shaped column 49. Through the arrangement of the above structure, the L-shaped pressure 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 mud, 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 residual impurities, thereby improving the cleanliness of the sponge roller 43 for the kelp.

[0026] When in use, hang the kelp to be dried on the hook 3, start the annular hanging track 2, and the annular hanging track 2 moves the kelp into the U-shaped drying line 1 through the hook 3. The kelp will pass through the salt water spray cleaning area, double-sided high-pressure air knife drying area, preheating and heating area, balanced dehumidification area, heating and drying area, and cooling and shaping area of the U-shaped drying line 1 in sequence. The salt water spray cleaning area will use salt water to spray and clean the kelp to remove the mud 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 moisture, preparing for the subsequent drying process. The process is prepared. The preheating zone is preheated to evaporate the moisture inside the kelp, forming a "sweating" phenomenon, which is beneficial to the subsequent drying process. The balanced dehumidification zone performs dehumidification treatment under constant temperature conditions, gradually removes moisture, forms micro channels, and further reduces the moisture content of the kelp. The heating and drying zone gradually increases the temperature for drying until the predetermined moisture content is reached. The cooling and shaping zone reduces the temperature to shape the dried kelp to maintain its shape and texture. Finally, the dried kelp is unloaded from the U-shaped drying line 1 and 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 each temperature zone can be set to a different temperature according to the drying needs of the kelp. Preheating zone (zone 1): temperature 50-55℃, the center temperature of the kelp is 50℃, the humidity of the box is relatively high, and the temperature inside and outside the main kelp is kept consistent to prevent the formation of a dense film on the surface, which is convenient for the next step of dehumidification. Balanced dehumidification zone (zone 2): temperature 55-60℃, adjust the air valve to control the wind speed, use weak wind to dehumidify, keep the humidity of the box low, gradually dehumidify, and form tiny channels; heating and drying zone (zone 3): temperature 65-70℃, adjust the air valve to control the wind speed, use strong wind to dehumidify and dry, and realize waste heat recovery and enter the waste heat heating of zone 1 for recycling; cooling and shaping zone (zone 4): temperature 50-55℃, 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 two layers, so that two independent drying lines are formed inside the U-shaped drying line 1. Each line uses a circular hanging track 2 to hang and transport kelp, which facilitates the uniform hanging and movement of the kelp and uniform heating. The upper and lower layers of the U-shaped drying line 1 can be used for drying kelp, which improves space utilization, and an appropriate distance is retained 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 the kelp into the salt water spray cleaning area of the U-shaped drying line 1 through the hook 3, the kelp will pass between the two sponge rollers 43, and the motor 422 will be started. The output end of the motor 422 drives the gear 423 to rotate, and one gear 423 drives the other gear 423 to rotate, so that the two gears 423 drive the rotating rod 41 to rotate, and the rotating rod 41 drives the sponge roller 43 to rotate. The rotation of the sponge roller 43 rolls and cleans the surface of the kelp, and the sponge roller 43 can effectively remove impurities such as mud, seaweed, and plankton on the surface of the kelp to ensure that the surface of the kelp is clean. The rolling effect of the sponge roller 43 can help the salt water to better penetrate the surface of the kelp, thereby improving the efficiency of the salt water spray cleaning, avoiding the waste of salt water, and reducing costs. At the same time, due to the contact between the notch cylinder 46 and the outside of the sponge roller 43, impurities such as mud, seaweed, and plankton adhering to the surface of the sponge roller 43 will be scraped into the notch cylinder 46, thereby transferring the impurities from the surface of the sponge roller 43 to the notch cylinder 46, effectively reducing The secondary pollution of impurities is reduced, and the impurities are prevented from flowing back to other kelp. When the rotating rod 41 rotates, the rotating rod 41 drives the shaft 44 to rotate through the belt, and the shaft 44 drives the spiral blade 45. The spiral blade 45 pushes the impurities scraped into the notch cylinder 46 downward, thereby further preventing the impurities from flowing back to the surface of the kelp again, thereby preventing the cleaning effect of the sponge roller 43 from decreasing or other kelp from being contaminated by the secondary pollution. When the rotating rod 41 rotates, the rotating rod 41 drives the L-shaped column 49 to rotate, and the circular L-shaped column 49 The semicircular shape of the column pushes the semicircular block 410 to drive the L-shaped pressure plate 48 to move along the inside of the slide frame 47 toward the sponge roller 43. The L-shaped pressure 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 impurities such as mud, 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 residual impurities, thereby improving the cleanliness of the sponge roller 43 for the kelp.

[0030] See also Figure 1 - Figure 8On the basis of the above embodiment, in another embodiment of the present invention, two water removal devices 5 are provided in the rear section of the salt water spray cleaning area of the U-shaped drying line 1. The water removal device 5 includes two chute frames 51 and two elastic telescopic plates 55. The two 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 chute frames 51, and a spring is provided between the fixed end of the elastic telescopic plate 55 and the chute frame 51. A splint 52 is fixed on the side where the telescopic ends of the two elastic telescopic plates 55 are close to each other. The tops of the two chute frames 51 are both horizontally slidably installed with L The L-shaped slide 54 is connected to the outer wall of the splint 52 on one side away from the slide frame 2 51. The tops of the two L-shaped slides 54 are hinged with a hinge rod 53. One end of the hinge rod 53 away from the L-shaped slide 54 is hinged to the outer wall of the L-shaped pressure plate 48. A number of inclined tubes 56 are evenly and equidistantly fixed on the side where the two splints 52 are away from each other. The two splints 52 are both arranged in a wavy shape. The wavy convex surface of the splint 52 on one side is opposite to the wavy concave surface of the splint 52 on the other side. The several inclined tubes 56 are all located below the convex surface on the side where the splints 52 are away from each other. The two splints 52 are close to each other and are provided with a plurality of inclined tubes 56. The internally connected through-holes, through the arrangement of the above structure, enable the two splints 52 to squeeze the kelp transmitted by the hook 3, and the squeezing effect of the splints 52 can accelerate the removal of moisture on the surface of the kelp, help reduce the moisture retained on the surface of the kelp, reduce the impact of moisture on the kelp, and lay the foundation for the subsequent drying process. In addition, the wavy splints 52 are designed so that when the two splints 52 are closed, the convex and concave surfaces of the wavy splints 52 can wrap the surface of the kelp more evenly, so that the moisture attached to the surface of the kelp can be squeezed out from the sponge roller 43 more effectively, and in this process, the inclined tube 56 will divert the water on the surface of the kelp outward, through the inclined tube Due to the diversion effect of the tube 56, the water is effectively guided to the outside instead of flowing down along the surface of the kelp, which 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 splint 52, avoiding excessive water from staying on the surface of the kelp and causing subsequent water retention. At the same time, through the setting of the above-mentioned structure, when the hook 3 drives the kelp to move, the kelp will move along the chute frame 51 away from the L-shaped pressure plate 48 with the splint 52 and the elastic telescopic plate 55, thereby avoiding the problem that after the two splints 52 clamp the kelp, the hook 3 continues to drive the kelp to move, causing the splint 52 to damage the kelp.

[0031] When in use, during the process of the L-shaped pressing plate 48 moving along the inside of the chute frame 1 47 toward the sponge roller 43, the L-shaped pressing plate 48 pulls the hinged rod 53 to drive the L-shaped slide plate 54 to move along the top of the chute frame 2 51 in the direction away from the chute frame 2 51, and the L-shaped slide plate 54 pushes the clamping plate 52 to move along, and the clamping plate 52 drives the telescopic end of the elastic telescopic plate 55 to stretch, so that the two clamping plates 52 are close to each other, and the two clamping plates 52 squeeze the kelp transmitted by the hook 3. The squeezing action of the clamping plates 52 can accelerate the removal of moisture from the surface of the kelp, help reduce the moisture retained on the surface of the kelp, reduce the impact of moisture on the kelp, and provide for subsequent The wavy splint 52 is designed so that when the two splints 52 are closed, the convex and concave surfaces of the wavy splint 52 can wrap the surface of the kelp more evenly, so that the moisture attached to the surface of the kelp can be squeezed out from the sponge roller 43 more effectively, and in this process, the inclined tube 56 will divert the water on the surface of the kelp outward. Through the diversion effect of the inclined tube 56, the water is effectively guided to the outside instead of flowing down along the surface of the kelp, which 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 splint 52, avoiding excessive moisture from staying on the surface of the kelp and causing subsequent moisture retention.

[0032] It should be noted that after the two splints 52 clamp the kelp, the hook 3 drives the kelp to move, and the kelp will move along the slide frame 51 away from the L-shaped pressure plate 48 with the splints 52 and the elastic telescopic plate 55, thereby avoiding the problem that the splints 52 will damage the kelp when the hook 3 continues to drive the kelp to move after the two splints 52 clamp the kelp.

[0033] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
