Description

Technical Field

[0001] This invention relates to the field of seaweed conveying technology, and in particular to a conveying device and a conveying method for baking seaweed. Background Technology

[0002] Baking seaweed sheets is a crucial step in the formation and shaping of their flavor. Because seaweed sheets are thin and light, they are prone to shifting when placed. When densely arranged, adjacent seaweed sheets may have too large a gap, affecting baking efficiency, or they may be too dense and overlap, resulting in poor baking results. Specifically, if seaweed sheets overlap during baking, color differences will occur at the overlapping areas. Therefore, before feeding the seaweed sheets into the baking machine, it is necessary to ensure that the seaweed sheets are fed densely one by one without overlapping.

[0003] Therefore, it is necessary to design a conveying device and a conveying method for seaweed baking to ensure the arrangement requirements of the seaweed sheets during the baking process. Summary of the Invention

[0004] To overcome the technical defects of the prior art, the present invention provides a conveying device and a conveying method for baking seaweed, which can ensure that the seaweed sheets are conveyed tightly in sequence without overlapping.

[0005] The technical solution adopted in this invention is:

[0006] A conveying device includes a seaweed feeding machine, a baking machine, a cooling machine, and a spreading machine connected in sequence. The seaweed feeding machine includes a feeding frame, a feeding robot, a feeding conveying system, a downward pressure control system, and a quick-release suction system. The quick-release suction system is mounted on the feeding robot, the feeding robot is mounted on the feeding frame, the feeding conveying system is mounted on the feeding frame, and the downward pressure control system is mounted on the feeding frame and spans across the feeding conveying system. The downward pressure control system includes a downward pressure... The pressure box comprises a pressure chamber, an airflow control plate, an air pressure deflector plate, and a reset elastic plate. The bottom of the pressure chamber is provided with a sensing nozzle and several pressure nozzles. The airflow control plate is slidably mounted on the side of the pressure chamber near the pressure nozzles. The air pressure deflector plate is rotatably mounted on the side of the sensing nozzle. The air pressure deflector plate is connected to the airflow control plate. The airflow control plate is provided with control holes adapted to the corresponding pressure nozzles. The reset elastic plate is mounted on the pressure chamber and is located on the side of the air pressure deflector plate away from the pressure nozzles.

[0007] Preferably, the baking machine includes a baking tunnel, and the baking tunnel is provided with a plurality of heating wires.

[0008] Preferably, the cooling machine includes a cooling tunnel on which a cooling fan is installed.

[0009] Preferably, the spreader is mounted across the feeding conveyor system.

[0010] Preferably, the loading robot includes a loading slide rail, a loading transverse slider, a loading lifting cylinder, and a loading lifting slider. The loading transverse slider is horizontally slidable on the loading slide rail, the loading lifting slider is vertically slidable on the loading transverse slider, the loading lifting cylinder is mounted on the loading transverse slider, the loading lifting cylinder is connected to the loading lifting slider in a transmission manner, and the quick unloading suction system is mounted on the loading lifting slider.

[0011] Preferably, the feeding and conveying system is a mesh belt conveyor.

[0012] Preferably, the quick-release suction system includes a suction tube, a traction piston, a traction rope, a push rod, and a rubber suction cup. The push rod is rotatably mounted on the lower side of the suction tube, and is rotatably mounted on the side of the suction tube near the lower pressure box. The rubber suction cup is sleeved on the lower side of the suction tube. The traction piston is slidably mounted inside the suction tube. The traction piston and the push rod are connected by a traction rope. The traction piston is provided with a negative pressure maintaining hole.

[0013] Preferably, the bottom of the air pressure deflector is provided with an arc, and the air pressure deflector is provided with a traction plate, which is connected to the air volume control plate in a transmission manner.

[0014] The conveying method for seaweed baking includes the following steps:

[0015] S1: Place the entire pile of seaweed sheets on the feeding frame. The quick-release suction system picks up the top layer of seaweed sheets. The feeding robot arm drives the quick-release suction system to the feeding conveyor system.

[0016] S2: After the pressure box is ventilated, the sensor nozzle sprays air, and a high pressure is formed between the seaweed sheet and the sensor nozzle, causing the pressure deflector plate to deflect. The pressure deflector plate drives the air volume control plate to descend, thus closing the pressure nozzle.

[0017] S3: After the seaweed sheet passes through, the air pressure below the sensing nozzle is released, causing the air pressure deflector to rotate. This causes the air pressure deflector to drive the air volume control plate to rise, opening the downward nozzle and pressing the seaweed sheet sucked up by the quick-release suction system onto the feeding conveyor system, so that the seaweed sheet is transported by the feeding conveyor system.

[0018] S4: After the seaweed sheets are baked in the baking machine, they enter the cooling machine to cool until they are spread by the spreading machine.

[0019] The beneficial effects of this invention are:

[0020] The seaweed feeding machine includes a feeding frame, a feeding robot, a feeding conveying system, a pressure control system, and a quick-release suction system. The quick-release suction system is mounted on the feeding robot and immediately releases the seaweed sheets as they move laterally along the underside of the quick-release suction system. The feeding robot is mounted on the feeding frame and drives the quick-release suction system to move laterally. The feeding conveying system is mounted on the feeding frame to transport the seaweed sheets. The pressure control system is mounted on the feeding frame and spans the feeding conveying system. The pressure control system includes a pressure box and an airflow control unit. The system comprises a pressure deflector plate, a pressure plate, and a reset elastic plate. The bottom of the pressure chamber is equipped with a sensing nozzle and several pressure nozzles, each pointing downwards towards the quick-release suction system. The airflow control plate is slidably mounted on the side of the pressure chamber near the pressure nozzle. The pressure deflector plate is rotatably mounted on the side of the sensing nozzle via a pin. The pressure deflector plate is connected to the airflow control plate via a transmission connection. The airflow control plate is equipped with control holes adapted to the corresponding pressure nozzles. The reset elastic plate is mounted on the pressure chamber and is located on the side of the pressure deflector plate away from the pressure nozzle.

[0021] When the seaweed sheet passes by, its blocking and sealing effect increases the air pressure at the nozzle of the sensing nozzle, causing the pressure deflector plate to rotate. This, in turn, causes the airflow control plate to descend, closing all the downward pressure nozzles. To prevent interference, the airflow control plate is made of elastic plastic. After the seaweed sheet passes by, the pressure at the sensing nozzle decreases, causing the pressure deflector plate to rotate under the action of the reset elastic plate. This causes the airflow control plate to rise, opening all the downward pressure nozzles. As a result, the seaweed sheet sucked up by the quick-release suction system is deflected towards the upward feeding system by the downward airflow from the downward pressure nozzles. The feeding system generates a lateral traction force on the seaweed sheet. After the seaweed sheet generates this lateral traction force, the quick-release suction system moves the seaweed sheet laterally along the lower side of the quick-release suction system, eventually throwing it off.

[0035] The present invention will be further described below with reference to the accompanying drawings:

[0036] like Figure 1 — Figure 7As shown, this embodiment provides a conveying device, including a seaweed feeding machine 1, a baking machine 2, a cooling machine 3, and a spreading machine 4 connected in sequence. The seaweed feeding machine 1 includes a feeding frame 11, a feeding robot 12, a feeding conveying system 13, a downward pressure control system 14, and a quick-release suction system 15. The quick-release suction system 15 is mounted on the feeding robot 12 and is used to immediately release the seaweed sheet 5 when it moves laterally along the lower side of the quick-release suction system 15. The feeding robot 12 is mounted on the feeding frame 11 and is used to drive the quick-release suction system 15 to move laterally. The feeding conveying system 13 is mounted on the feeding frame 11 to realize the conveying of the seaweed sheet 5. The downward pressure control system 14 is mounted on the feeding frame 11 and spans the feeding conveying system 13. The downward pressure control system 14 includes a downward pressure box 141, an air volume control board 142, and an air pressure deflector. The pressure box 141 has a sensing nozzle 1411 and several pressure nozzles 1412 at its bottom. Each pressure nozzle 1412 points downwards towards the quick-release suction system 15. The air volume control plate 142 is slidably installed on the side of the pressure box 141 near the pressure nozzle 1412. The air pressure deflector plate 143 is rotatably installed on the side of the sensing nozzle 1411 via a pin. The air pressure deflector plate 143 is connected to the air volume control plate 142. The air volume control plate 142 has a control hole 1421 that matches the corresponding pressure nozzle 1412. The reset elastic plate 144 is installed on the pressure box 141. The reset elastic plate 144 is located on the side of the air pressure deflector plate 143 away from the pressure nozzle 1412. The reset elastic plate 144 is an elastic plastic sheet used to reset the air pressure deflector plate 143.

[0037] When the seaweed sheet 5 passes by, due to its blocking and sealing effect, it increases the air pressure at the nozzle 1411, causing the pressure deflector 143 to deflect and rotate. This, in turn, causes the airflow control plate 142 to descend, sealing each downward-pressing nozzle 1412. To prevent interference, the airflow control plate 142 is made of elastic plastic. After the seaweed sheet 5 passes by, the pressure at the nozzle 1411 decreases, causing the pressure deflector 143 to return to its original position. The rotating plate 144 drives the air volume control plate 142 to rise, opening each downward pressure nozzle 1412. This causes the seaweed sheet 5 sucked by the quick-release suction system 15 to be blown by the downward airflow from the downward pressure nozzle 1412 and deflected towards the upward material conveying system 13. The conveying of the upward material conveying system 13 causes the seaweed sheet 5 to generate a lateral traction force. After the seaweed sheet 5 generates a lateral traction force, the seaweed sheet 5 moves laterally along the lower side of the quick-release suction system 15 and is then thrown down.

[0038] Specifically, the baking machine 2 includes a baking tunnel, which is equipped with several heating wires to achieve heating and drying, and to bake the seaweed sheets 5.

[0039] Specifically, the cooling machine 3 includes a cooling tunnel, on which a cooling fan is installed to cool the seaweed sheets 5, making it easier for subsequent packaging.

[0040] Specifically, the spreading machine 4 is installed across the feeding and conveying system 13 to spray seasoning powder to achieve seasoning, which will not be elaborated here.

[0041] Specifically, the loading robot 12 includes a loading slide rail 121, a loading transverse slider 122, a loading lifting cylinder 123, and a loading lifting slider 124. The loading transverse slider 122 is horizontally slidably mounted on the loading slide rail 121. The loading transverse slider 122 achieves transverse movement through a commercially available screw-slider structure, which will not be described in detail here. The loading lifting slider 124 is vertically slidably mounted on the loading transverse slider 122. The loading lifting cylinder 123 is mounted on the loading transverse slider 122 and is connected to the loading lifting slider 124 via a transmission. The quick unloading suction system 15 is mounted on the loading lifting slider 124 to realize the lifting of the quick unloading suction system 15.

[0042] Specifically, the feeding conveyor system 13 is a mesh belt conveyor, which facilitates the airflow after it is ejected from the sensing nozzle 1411 and passes through the feeding conveyor system 13. This allows the airflow to pass smoothly when no seaweed sheet 5 is passing through. The air pressure deflector plate 143 can deflect, thereby controlling the seaweed sheet 5 to deflect towards the feeding conveyor system 13 under the blowing of the downward airflow ejected from the pressure nozzle 1412. This causes the seaweed sheet 5 to move laterally under the traction of the feeding conveyor system 13, so that the quick-release suction system 15 is separated from the seaweed sheet 5.

[0043] Specifically, the quick-release suction system 15 includes a suction pipe 151, a traction piston 152, a traction rope 153, a push rod 154, and a rubber suction cup 155. The suction pipe 151 is connected to a negative pressure fan. The push rod 154 is rotatably mounted on the lower side of the suction pipe 151 via a pin. The push rod 154 is rotatably mounted on the side of the suction pipe 151 near the lower pressure box 141, so that when the push rod 154 falls and the seaweed sheet 5 moves laterally, the rotation of the push rod 154 pushes the seaweed sheet 5 to fall. The rubber suction cup 155 is sleeved on the lower side of the suction pipe 151 and is elastic. The traction piston 152 is slidably mounted inside the suction pipe 151. The traction piston 152 and the push rod 154 are connected by a traction rope 153. The traction piston 152 is provided with a negative pressure maintaining hole 1521. When suctioning the seaweed sheet 5, the negative pressure air cannot pass through the negative pressure maintaining hole 1521 in time, so the negative pressure air... The traction piston 152 rises immediately, causing the push rod 154 to rotate upwards. At this time, the rubber suction cup 155 approaches the seaweed sheet 5 and sucks it up. When the traction piston 152 moves to the upper limit position, the negative pressure maintaining hole 1521 maintains negative pressure. After sucking up the seaweed sheet 5, due to the obstruction of the seaweed sheet 5, the air passing through the negative pressure maintaining hole 1521 decreases, and the air pressure difference between the upper and lower sides of the traction piston 152 decreases, causing the traction piston 152 to fall. The push rod 154 rotates downwards until it presses on the seaweed sheet 5. When the seaweed sheet 5 touches the feeding conveying system 13 under the action of the downward airflow from the downward nozzle 1412, the seaweed sheet 5 overcomes the elasticity of the rubber suction cup 155 and moves laterally. The push rod 154 rotates downwards and pushes the seaweed sheet 5 away from the rubber suction cup 155. At this time, under the fixing action of the downward airflow from the downward nozzle 1412 and the conveying of the feeding conveying system 13, the seaweed sheet 5 is conveyed away.

[0044] Specifically, the bottom of the pressure deflector plate 143 is provided with an arc 1431, which allows the pressure deflector plate 143 to rotate at a sufficient angle when it is adapted to the seaweed sheet 5, ensuring sufficient stroke of the air volume control plate 142. The pressure deflector plate 143 is provided with a traction plate 1432, which is connected to the air volume control plate 142 in a transmission manner. The pressure deflector plate 143 maintains the pressure between itself and the seaweed sheet 5 when it rotates.

[0045] The conveying method for seaweed baking includes the following steps:

[0046] S1: Place the entire pile of seaweed sheets 5 on the feeding frame 11. The quick-release suction system 15 picks up the top layer of seaweed sheets 5. The feeding robot 12 drives the quick-release suction system 15 to move to the feeding conveyor system 13.

[0047] S2: After the pressure box 141 is ventilated, the sensing nozzle 1411 sprays air, and a high pressure is formed between the seaweed sheet 5 and the sensing nozzle 1411, causing the pressure deflector plate 143 to deflect. The pressure deflector plate 143 drives the air volume control plate 142 to descend, thus closing the pressure nozzle 1412.

[0048] S3: After the seaweed sheet 5 passes through, the air pressure under the sensing nozzle 1411 is released, causing the air pressure deflector plate 143 to rotate. This causes the air pressure deflector plate 143 to drive the air volume control plate 142 to rise, causing the downward pressure nozzle 1412 to open. This presses the seaweed sheet 5 sucked by the quick-release suction system 15 down onto the feeding conveyor system 13, so that the seaweed sheet 5 is conveyed by the feeding conveyor system 13. Since the air pressure deflector plate 143 rotates immediately after the seaweed sheet 5 passes through, the next seaweed sheet 5 will be immediately subjected to the downward pressure of the downward pressure nozzle 1412 and conveyed by the feeding conveyor system 13, ensuring that the seaweed sheets 5 are conveyed tightly in sequence without overlapping.

[0049] S4: After the seaweed sheet 5 is baked by the baking machine 2, it enters the cooling machine 3 for cooling until it is fed by the spreading machine 4.

[0050] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments.
