[0021] like Figures 1 to 10 As shown, a continuous circulation drying device for mugwort products includes a conveyor 1 and a blower 4. A drying box 2 is mounted on the upper part of the conveyor 1. An opening and closing component and a turning component are provided inside the drying box 2.

The motor 301 drives the half gear 302 to rotate, and the half gear 302 meshes with the tooth blocks 304 on the upper and lower sides of the frame plate 303, which in turn drives the frame plate 303 to slide left and right along the inner wall of the drying box 2. The left and right reciprocating motion of the frame plate 303 drives the hollow plate 306 to move through the pull rod 1 305. When the hollow plate 306 approaches the frame plate 303, the pawl 307 meshes with the ratchet 309, thereby driving the ratchet 309 to rotate. The ratchet 309 then drives the concave wheel 310 to rotate through the transmission of the straight rod 308. During the rotation of the concave wheel 310, the air bag 311 is squeezed. At the same time, The groove of the concave wheel 310 loses the obstruction of the airbag 311 and passes through. At this time, air can enter the air outlet pipe 6 through the groove. When the hollow plate 306 is away from the frame plate 303, the pawl 307 and the ratchet 309 slide. When reciprocating again, the ratchet 309 is pushed to rotate again.

[0022] like Figure 2 、 Figure 3 、 Figure 6 and Figure 7 As shown, the flip assembly includes a side box 701 fixedly connected to the inner wall of the drying box 2, the side inner wall of the side box 701 is limitedly slidably connected to a rack 702, the bottom end of the rack 702 is hinged to a connecting rod 704, the inner wall of the side box 701 is rotatably connected to a rocker 705, the top of the rocker 705 is hinged to the connecting rod 704, the rotating axis of the rocker 705 is fixedly connected to a pendulum 706, the inner wall of the drying box 2 is rotatably connected to a center rod 707, the center rod 70 The outer surface of 7 is fixedly connected to a folding plate 709, the upper part of the central rod 707 is fixedly connected to a limit plate 710, and the angle between the limit plate 710 and the folding plate 709 is 90 degrees. The side of the frame plate 303 away from the pull rod 1 305 is hinged to the pull rod 2 703, and the end of the pull rod 2 703 away from the frame plate 303 is hinged to the rack 702. The outer surface of the end of the central rod 707 is fixedly sleeved with a gear 1 708, and the gear 1 708 is meshed with the balance wheel 706; During the movement of the frame plate 303, the rack 702 will be driven by the pull rod 2 703 to slide up and down inside the side box 701, and then the rocker arm 705 will be driven to swing around the rotation point through the connecting rod 704. At the same time, the rocker arm 705 will drive the balance wheel 706 to swing synchronously. The balance wheel 706 will drive the gear 1 708 to rotate during the swinging process, and then drive the center rod 707 to rotate. The folding plate 709 will lift the mugwort products conveyed to the folding plate 709 as the center rod 707 rotates. As the rotation angle of the folding plate 709 increases, the mugwort products will slide to the junction of the folding plate 709 and the center rod 707, but will not slide due to the resistance of the limit plate 710. When the folding plate 709 rotates to a vertical state, under the action of gravity, the mugwort products will flip over and fall on the conveyor 1. In this way, the purpose of flipping the mugwort products is achieved, making the drying of the mugwort products more uniform and improving the drying efficiency.

[0023] like Figures 6 to 8 As shown, the partition assembly includes a shaft 801 that is movably inserted into the middle of the outer surface of the side box 701, and the outer surface of the part of the shaft 801 that extends into the inner part of the side box 701 is fixedly sleeved with a gear 2 802, and the gear 2 802 is meshed and connected with the rack 702, and the part of the shaft 801 that extends out of the side box 701 is fixedly sleeved with a partition plate 803, and the partition plate 803 is placed in the middle of the drying box 2, and the upper and lower sides of the partition plate 803 are connected with a flap 804, and the side of the flap 804 away from the partition plate 803 is connected with a slide plate 805, and the outer surface of the side box 701 is provided with a slide groove 806, and the slide plate 805 is slidably connected to the inside of the slide groove 806; The rack 702 will drive the spur gear 802 to rotate during the up and down movement, and then drive the shaft 801 to rotate, and the partition plate 803 will rotate around the shaft 801, and the upper and lower sides of the partition plate 803 will drive the flap 804 to rotate. Since the other side of the flap 804 is connected to the slide plate 805, and the slide plate 805 is limited by the slide groove 806 and can only slide inside the slide groove 806, the slide groove 806 slides to make the flap 804 and the partition plate 803 rotate and fold, which can make room for the rotation of the folding plate 709. In addition, it also has the effect of dividing the drying box 2, so that the drying box 2 is divided into high heat and low heat two parts, the high heat near the air inlet pipe 5 and the low heat near the air outlet pipe 6. Such separation and dredging are staggered and run, which can make the hot air gather in the high heat area, thereby improving the drying effect of the wormwood products and ensuring the thoroughness of the drying.

[0024] like Figure 5 and Figure 9As shown, the reset assembly includes a rubber ring 901 provided on the inner wall of the airbag 311. Hinge shafts 902 are provided on the upper and lower inner walls of the rubber ring 901. A pressure plate 903 is movably provided on the outer surface of the hinge shaft 902. The end of the pressure plate 903 away from the hinge shaft 902 is hinged to a balance plate 904. A spring 905 is fixedly connected to the side of the balance plate 904.

At the same time, the pressure plate 903 will push the balance plate 904 to squeeze the spring 905. After the airbag 311 loses the squeezing force, the rubber ring 901 will be propped up under the action of the rebound force of the spring 905, thereby making the airbag 311 full again, ensuring the rebound effect of the airbag 311.

[0025] like Figure 1 、 Figure 3 and Figure 10 As shown, the air outlet end of the blower 4 is fixedly connected to the air inlet pipe 5, and the end of the air inlet pipe 5 away from the blower 4 is fixedly connected to the outer surface of the drying box 2. A heating mechanism 11 is provided at the connection between the air inlet pipe 5 and the drying box 2, and a preheating component is provided inside the end of the air inlet pipe 5 close to the blower 4; The preheating assembly includes a docking plate 1001 arranged at the junction of the outlet pipe 6 and the inlet pipe 5, and the docking plate 1001 is provided with two pieces and distributed on both sides of the inlet pipe 5. The surfaces of the two docking plates 1001 are fixedly connected with branch pipes 1002, and the branch pipes 1002 all penetrate the inlet pipe 5. A transmission rod 1003 is movably inserted into the side of the inlet pipe 5, and the end of the transmission rod 1003 extending into the inlet pipe 5 is fixedly connected to a fan blade 1004, and the end of the transmission rod 1003 extending out of the inlet pipe 5 is fixedly connected to a driving wheel 1005, and a round rod 1006 is movably inserted into the outer surface of the outlet pipe 6, and the end of the round rod 1006 extending out of the outlet pipe 6 is fixedly connected to a driven wheel 1007, and the driven wheel 1007 is meshed with the driving wheel 1005. The outer surface of the round rod 1006 is distributed with fan plates 1008 in a ring matrix; The air discharged from the exhaust pipe 6 will be diverted from the docking plate 1001 into each branch pipe 1002 when it approaches the intake pipe 5. The branch pipe 1002 runs through the intake pipe 5. The air gathered by the blower 4 will first pass through the branch pipe 1002 to achieve the preheating effect, and the design of the branch pipe 1002 can increase the contact area, thereby improving the heat conversion efficiency. In addition, the air blown by the blower 4 will drive the fan blades 1004 to rotate, and then increase the transmission rod 1003 and the driving wheel 1005 to drive the driven wheel 1007 and the round rod 1006 to rotate, so that the fan plate 1008 rotates. The rotation of the fan plate 1008 can play a role in the alternation of closing and unobstructed of the exhaust pipe 6, thereby extending the time for heat exchange between the exhaust air and the incoming intake air, further improving the preheating effect, and achieving the purpose of waste heat utilization.

[0026] The technical solution provided by the present invention is that during the drying process of wormwood products, the produced wormwood products are continuously transported by the conveyor 1 and enter the drying box 2. The blower 4 operates to suck air into the air inlet pipe 5, which is heated by the heating mechanism 11 to become hot air and transported to the drying box 2 to dry the wormwood products. The air is discharged from the air outlet pipe 6 at the other end to achieve continuous cycle drying. During the drying process, the motor 301 drives the half gear 302 to rotate, and the half gear 302 and the gears on the upper and lower sides of the frame plate 303 are rotated. The blocks 304 are staggered and meshed, which in turn drives the frame plate 303 to slide left and right along the inner wall of the drying box 2. The left and right reciprocating motion of the frame plate 303 drives the hollow plate 306 to move through the pull rod 305. When the hollow plate 306 approaches the frame plate 303, the pawl 307 engages with the ratchet 309, thereby driving the ratchet 309 to rotate. The ratchet 309 then drives the concave wheel 310 to rotate through the transmission of the straight rod 308. Since the air bag 311 is stuck in the groove of the concave wheel 310, the concave wheel 310 squeezes the air bag during its rotation. The airbag 311 is released, and the groove of the concave wheel 310 loses the obstruction of the airbag 311 and passes through. At this time, air can enter the outlet pipe 6 through the groove. When the hollow plate 306 is away from the frame plate 303, the pawl 307 slides with the ratchet 309. When the hollow plate 306 is moved back and forth again, the ratchet 309 is pushed to rotate again. The concave wheel 310 rotates again so that the airbag 311 is engaged with the groove of the concave wheel 310, thereby sealing the outlet pipe 6. How to achieve the effect of opening and closing the outlet pipe 6 in intervals by reciprocating so that the hot air can stay in the drying box 2 , thereby extending the contact time of hot air with the wormwood product and improving the heat conversion efficiency. When the airbag 311 is compressed, the rubber ring 901 inside the airbag 311 will be squeezed, and the rubber ring 901 will be deformed and push the pressure plate 903 to rotate around the hinge shaft 902. At the same time, the pressure plate 903 will push the balance plate 904 to squeeze the spring 905. After the airbag 311 loses its squeezing force, the rubber ring 901 will be propped up under the action of the rebound force of the spring 905, thereby making the airbag 311 full again, ensuring the rebound effect of the airbag 311; When the folding plate 709 rotates to the vertical position, the wormwood product will slide to the junction of the folding plate 709 and the center rod 707, but will not slide due to the resistance of the limit plate 710. When the folding plate 709 rotates to the vertical position, the wormwood product will flip over and fall on the conveyor 1 under the action of gravity. In this way, the purpose of flipping the wormwood product is achieved, making the drying of the wormwood product more uniform and improving the drying effect. The sprocket 802 is rotated by the gear 803, and the sprocket 803 is rotated by the gear 804. The sprocket 803 is rotated by the gear 804, and the sprocket 803 is rotated by the gear 804. The air discharged from the exhaust pipe 6 will be diverted from the docking plate 1001 into each branch pipe 1002 when it approaches the intake pipe 5. The branch pipe 1002 runs through the intake pipe 5. The air gathered by the blower 4 will first pass through the branch pipe 1002 to achieve the preheating effect, and the design of the branch pipe 1002 can increase the contact area, thereby improving the heat conversion efficiency. In addition, the air blown by the blower 4 will drive the fan blades 1004 to rotate, and then increase the transmission rod 1003 and the driving wheel 1005 to drive the driven wheel 1007 and the round rod 1006 to rotate, so that the fan plate 1008 rotates. The rotation of the fan plate 1008 can play a role in the alternation of closing and unobstructed of the exhaust pipe 6, thereby increasing the time for heat exchange between the exhaust air and the incoming intake air, further improving the preheating effect, and achieving the purpose of waste heat utilization.
