Description

Technical Field

[0001] The present invention relates to the technical field of seaweed conveying, and in particular to a conveying device and a conveying method for baking seaweed. Background Art

[0002] Baking nori sheets is a key step in forming and shaping the flavor of nori sheets. Since nori sheets are thin and light, they are easy to move when placed. When they are densely arranged, adjacent nori sheets may be too far apart, affecting the baking efficiency, or they may be too dense and overlap, resulting in poor baking effect. Specifically, if overlap occurs during baking, not only will color difference occur at the overlapping position, but before the nori sheets are transported into the baking machine, it is necessary to ensure that the nori sheets are transported densely one by one, and the nori sheets cannot overlap.

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

The push rod is rotatably installed on the lower side of the suction tube. The push rod is rotatably installed on the side of the suction tube close to the lower pressure box. The rubber suction cup is sleeved on the lower side of the suction tube. The traction piston is slidably installed in the suction tube.

[0012] Preferably, a circular arc is provided at the bottom of the air pressure deflection plate, a traction plate is provided on the air pressure deflection plate, and the traction plate is transmission-connected to the air volume control plate.

[0013] The conveying device is used for conveying the seaweed baking method, comprising the following steps: S1: Place the entire pile of nori sheets on the loading rack. The quick-release suction system sucks the top layer of nori sheets. The loading robot drives the quick-release suction system to move to the loading conveyor system. S2: After the lower pressure box is ventilated, air is ejected from the sensing nozzle. High pressure is generated between the seaweed sheet and the sensing nozzle, causing the air pressure deflection plate to deflect. The air pressure deflection plate drives the air volume control plate downward, closing the lower pressure nozzle. S3: After the seaweed sheet passes through, the air pressure on the lower side of the nozzle is released, causing the air pressure deflection plate to rotate, causing the air pressure deflection plate to drive the air volume control plate to rise, causing the downward pressure nozzle to open, and the seaweed sheet sucked by the quick-release suction system is pressed down onto the feeding conveying system, so that the seaweed sheet is transported by the feeding conveying system; S4: After being baked by the baking machine, the seaweed sheets enter the cooling machine for cooling until being spread by the spreading machine.

[0014] The beneficial effects of the present invention are: 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 installed on the feeding robot to immediately put down the seaweed sheet when the seaweed sheet moves laterally along the lower side of the quick-release suction system. The feeding robot is installed on the feeding frame to drive the quick-release suction system to move laterally. The feeding conveying system is installed on the feeding frame to realize the transportation of the seaweed sheet. The downward pressure control system is installed on the feeding frame.

[0015] When the seaweed sheet passes through, due to the blocking and sealing effect of the seaweed sheet, the seaweed sheet increases the air pressure at the ejection position of the sensing nozzle, causing the air pressure deflection plate to rotate obliquely, thereby driving the air volume control plate to descend and closing each downward pressure nozzle. In order to prevent the air volume control plate from interfering, the air volume control plate is made of an elastic plastic sheet. After the seaweed sheet passes through, the pressure of the sensing nozzle decreases, causing the air pressure deflection plate to rotate driven by the reset elastic plate, driving the air volume control plate to rise, opening each downward pressure nozzle, causing the seaweed sheet sucked by the quick-release suction system to be blown by the downward airflow ejected from the downward pressure nozzle, and the direction of the upper material conveying system is deflected. The conveying of the upper material conveying system causes the seaweed sheet to generate lateral traction. After the quick-release suction system generates lateral traction on the nori sheet, the nori sheet moves laterally along the lower side of the quick-release suction system, thereby throwing the nori sheet down.

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1 — Figure 7As shown, this embodiment provides a conveying device, including a seaweed loader 1, a baking machine 2, a cooling machine 3 and a spreading machine 4 connected in sequence, the seaweed loader 1 includes a loading frame 11, a loading robot 12, a loading conveying system 13, a downward pressure control system 14 and a quick-release suction system 15, the quick-release suction system 15 is installed on the loading robot 12, and is used to immediately put down the seaweed sheet 5 when the seaweed sheet 5 moves laterally along the lower side of the quick-release suction system 15, the loading robot 12 is installed on the loading frame 11, and is used to drive the quick-release suction system 15 to move laterally, the loading conveying system 13 is installed on the loading frame 11, and realizes the transportation of the seaweed sheet 5, the downward pressure control system 14 is installed on the loading frame 11, and the downward pressure control system 14 spans the loading conveying system 13, and the downward pressure control system 14 includes a downward pressure box 141, an air volume control plate 142, an air pressure biasing plate 143, and an air pressure deflection plate 144. The inclined plate 143 and the reset elastic plate 144, the bottom of the lower pressure box 141 is provided with a sensing nozzle 1411 and several downward pressure nozzles 1412, each downward pressure nozzle 1412 points to the quick-release suction system 15 in an oblique downward direction, the air volume control plate 142 is slidably mounted on the side of the lower pressure box 141 close to the downward pressure nozzle 1412, the air pressure deflection plate 143 is rotatably mounted on the side of the sensing nozzle 1411 through a pin shaft, the air pressure deflection plate 143 is transmission-connected to the air volume control plate 142, and the air volume control plate 142 is provided with a control hole 1421 adapted to the corresponding downward pressure nozzle 1412, the reset elastic plate 144 is mounted on the lower pressure box 141, the reset elastic plate 144 is located on the side of the air pressure deflection plate 143 away from the downward pressure nozzle 1412, and the reset elastic plate 144 is an elastic plastic sheet used to reset the air pressure deflection plate 143.

[0025] When the seaweed sheet 5 passes by, due to the blocking and sealing effect of the seaweed sheet 5, the seaweed sheet 5 increases the air pressure at the ejection position of the sensing nozzle 1411, causing the air pressure deflection plate 143 to deflect and rotate, thereby driving the air volume control plate 142 to descend and close each downward pressure nozzle 1412. In order to prevent the air volume control plate 142 from interfering, the air volume control plate 142 is made of an elastic plastic sheet. After the seaweed sheet 5 passes by, the pressure of the sensing nozzle 1411 decreases, causing the air pressure deflection plate 143 to reset in the reset spring. The plate 144 drives the downward rotation, drives the air volume control plate 142 to rise, opens each downward pressure nozzle 1412, and causes the seaweed sheet 5 sucked by the quick-release suction system 15 to be blown by the downward airflow ejected from the downward pressure nozzle 1412, and deflected toward the upper feeding conveying system 13. The conveying of the upper feeding conveying system 13 causes the seaweed sheet 5 to generate a lateral traction force. After the quick-release suction system 15 generates a lateral traction force on the seaweed sheet 5, the seaweed sheet 5 moves laterally along the lower side of the quick-release suction system 15, and then throws the seaweed sheet 5 down.

[0026] Specifically, the baking machine 2 includes a baking tunnel, in which a plurality of electric heating wires are provided to achieve heating and drying, and bake the seaweed sheet 5.

[0027] Specifically, the cooling machine 3 includes a cooling tunnel, and a cooling fan is installed on the cooling tunnel to cool the seaweed sheet 5, which is convenient for subsequent packaging.

[0028] 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 described in detail here.

[0029] Specifically, the loading robot 12 includes a loading slide rail 121, a loading transverse sliding slider 122, a loading lifting cylinder 123 and a loading lifting slider 124. The loading transverse sliding slider 122 can be horizontally slidably installed on the loading slide rail 121. The loading transverse sliding slider 122 realizes transverse movement through a commercially available screw slider structure, which will not be repeated here. The loading lifting slider 124 can be lifted and slidably installed on the loading transverse sliding slider 122. The loading lifting cylinder 123 is installed on the loading transverse sliding slider 122. The loading lifting cylinder 123 is transmission-connected to the loading lifting slider 124. The quick-release suction system 15 is installed on the loading lifting slider 124 to realize the lifting and lowering of the quick-release suction system 15.

[0030] Specifically, the feeding conveying system 13 is a mesh belt conveying device, which facilitates the air to pass through the feeding conveying system 13 after being ejected from the sensing nozzle 1411, so that the air flow can pass smoothly when there is no seaweed sheet 5 passing through. The air pressure deflection plate 143 can be deflected, thereby controlling the seaweed sheet 5 to deflect toward the feeding conveying system 13 under the blowing of the downward airflow ejected from the downward pressure nozzle 1412, thereby causing the seaweed sheet 5 to move laterally under the traction of the feeding conveying system 13, so that the quick-release suction system 15 is separated from the seaweed sheet 5.

[0031] The suction pipe 151 is connected with the negative pressure fan, and the push rod 154 is rotatably mounted on the lower side of the suction pipe 151 through a pin shaft. The push rod 154 is rotatably mounted on the side of the suction pipe 151 close to the lower pressure box 141, so that after the push rod 154 falls, when the seaweed sheet 5 moves horizontally, the rotation of the push rod 154 pushes the seaweed sheet 5 to fall, and the rubber suction cup 155 is sleeved on the lower side of the suction pipe 151. The rubber suction cup 155 is elastic, and the traction piston 152 is slidably mounted in the suction pipe 151. The traction piston 152 and the push rod 154 are connected by the traction rope 153. A negative pressure maintaining hole 1521 is provided in the traction piston 152. When the seaweed sheet 5 is sucked, the negative pressure air does not have time to pass through the negative pressure maintaining hole 1521, so that the negative pressure air The traction piston 152 is driven to rise immediately, causing the push rod 154 to rotate upward. At this time, the rubber suction cup 155 approaches the nori sheet 5 and sucks the nori sheet 5. When the traction piston 152 moves to the upper limit position, the negative pressure maintaining hole 1521 maintains the negative pressure. After sucking the nori sheet 5, due to the obstruction of the nori sheet 5, the air passing through the negative pressure maintaining hole 1521 becomes less, and the air pressure difference between the upper and lower sides of the traction piston 152 is reduced, causing the traction piston 152 to fall, and the push rod 154 rotates downward until it presses on the nori sheet 5. Until the nori sheet 5 touches the feeding conveying system 13 under the action of the downward pressure airflow from the downward pressure nozzle 1412, the nori sheet 5 overcomes the elasticity of the rubber suction cup 155 and moves laterally, the push rod 154 rotates downward, and the push rod 154 pushes the nori sheet 5 away from the rubber suction cup 155. At this time, under the fixing effect of the downward pressure airflow ejected from the downward pressure nozzle 1412 and the conveying of the feeding conveying system 13, the nori sheet 5 is conveyed away.

[0032] Specifically, a circular arc 1431 is provided at the bottom of the air pressure deflection plate 143, so that the air pressure deflection plate 143 can rotate to a sufficient angle when it is adapted to the nori sheet 5, ensuring sufficient travel of the air volume control plate 142. A traction plate 1432 is provided on the air pressure deflection plate 143, and the traction plate 1432 is transmission-connected to the air volume control plate 142. The air pressure deflection plate 143 maintains pressure between itself and the nori sheet 5 when rotating.

[0033] The conveying device is used for conveying the seaweed baking method, comprising the following steps: S1: The whole pile of nori sheets 5 is placed on the loading rack 11. The quick-release suction system 15 sucks the top layer of nori sheets 5. The loading robot 12 drives the quick-release suction system 15 to move to the loading conveying system 13. S2: After the lower pressure box 141 is ventilated, the sensing nozzle 1411 ejects air. A high pressure is generated between the seaweed sheet 5 and the sensing nozzle 1411, causing the air pressure deflection plate 143 to deflect. The air pressure deflection plate 143 drives the air volume control plate 142 downward, closing the lower pressure nozzle 1412. S3: After the nori sheet 5 passes through, the air pressure on the lower side of the nozzle 1411 is sensed to be released, causing the air pressure deflection plate 143 to rotate, causing the air pressure deflection plate 143 to drive the air volume control plate 142 to rise, causing the downward pressure nozzle 1412 to open, and the nori sheet 5 sucked by the quick-release suction system 15 to be pressed down onto the feeding conveying system 13, so that the nori sheet 5 is conveyed by the feeding conveying system 13. Since the air pressure deflection plate 143 rotates immediately after the nori sheet 5 passes through, the next nori sheet 5 will be immediately subjected to the downward pressure of the downward pressure nozzle 1412 and conveyed by the feeding conveying system 13, ensuring that the nori sheets 5 are conveyed in sequence and closely without overlapping; S4: After being baked by the baking machine 2, the seaweed sheet 5 enters the cooling machine 3 for cooling until being spread by the spreading machine 4.
