[0023] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0024] like Figure 1-3As shown, a glue-spraying cotton oven is used as an example of a multi-layer continuous conveyor for explanation. The glue-spraying cotton oven includes a box 100, a heating box 300 and a conveying mechanism. The heating box 300 is arranged on the side of the box 100, and the conveying mechanism is arranged in the box 100 to convey the glue-spraying cotton. The glue-spraying cotton oven is sequentially provided with three layers of boxes 100 from top to bottom. The first and second layers of boxes 100 are provided with glue spraying nozzles 22. The transition between the first and second layers of boxes 100 and the transition between the second and third layers of boxes 100 are provided with auxiliary turning devices 200. The aforementioned transition refers to the exit of the conveying mechanism of the first layer of boxes 100 and the entrance of the conveying mechanism of the second layer of boxes 100, as well as the exit of the conveying mechanism of the second layer of boxes 100 and the entrance of the conveying mechanism of the third layer of boxes 100.

[0025] The auxiliary flipping device 200 in this embodiment includes a connecting plate 1, an upper transition plate 2, an upper transition plate baffle 3, a lower transition plate 4, a lower transition plate baffle 5, a transition roller 6, a movable connection block 7, a telescopic plate 8, an electric cylinder 9, a push rod 10 and a single-ear sleeve 11. The main body of the auxiliary flipping device is formed by connecting the upper transition plate 2 and the lower transition plate 4 through the connecting plate 1. The upper transition plate 2 and the lower transition plate 4 are connected at the transition point between the two layers of the spray-bonded cotton oven by bolts. The upper transition plate 2 and the lower transition plate 4 are provided with a transition roller 6. An arc guide groove is formed between the upper transition plate 2 and the lower transition plate 4. After the spray-bonded cotton enters the auxiliary flipping device 200, it slides along the arc guide groove to achieve flipping. In a specific embodiment, the upper transition plate baffle 3 and the lower transition plate baffle 5 are provided at the transition roller 6 to prevent the spray-bonded cotton from falling.

[0026] Furthermore, the upper transition plate 2 includes a movable connection block 7, a fixed plate 201, a movable plate 202 and a telescopic plate 8. The fixed plate 201 and the movable plate 202 are respectively connected to the upper and lower ends of the movable connection block 7 by bolts. The telescopic plate 8 is provided at the movable connection block 7, and the telescopic plate 8 is connected between the fixed plate 201 and the movable plate 202. The end of the movable plate 202 away from the movable connection block 7 is connected to the electric cylinder 9 through the single-ear sleeve 11 and the push rod 10. The electric cylinder 9 is fixed to the fixed plate. When the spray-bonded cotton moves to the telescopic plate 8, if wrinkles occur and affect the movement of the spray-bonded cotton, the electric cylinder 9 can be used to drive the movable plate 202 to swing up and down through the push rod 10 and the single-ear sleeve 11, so that the telescopic plate 8 is stretched or compressed, so as to remove the wrinkles of the spray-bonded cotton, thereby ensuring the accurate turning effect of the spray-bonded cotton.

[0027] In a specific embodiment, an upper air vent plate 12 is disposed above the box 100, and the heating box 300 includes a heating rod 14 and a fan 13. The heating rod 14 heats the air and then blows the dry hot air to the spray-bonded cotton through the upper air vent plate 12 through the fan 13. Furthermore, a lower air vent plate 23 is disposed below the box 100, and part of the blown hot air is returned to the heating box 300 through the lower air vent plate 23 for subsequent drying process.

[0028] Combination Figure 4 As shown, in a specific embodiment, the conveying mechanism includes a conveyor belt 15, a pressing roller 16, a feeding roller 17, a cloth conveying motor 18 and a sprocket group, wherein the sprocket group includes an upper synchronous sprocket group 21 and a lower sprocket 20, the upper synchronous sprocket group 21 is used to drive the pressing roller 16 and the feeding roller 17, and the lower sprocket 20 is used for the rotation of the conveyor belt 15. The cloth conveying motor 18 drives the sprocket group to rotate, so that the spray-bonded cotton is squeezed into the box 100 with a speed difference under the pressure of the pressing roller 16 and the feeding roller 17 and the support of the conveyor belt 15 for drying. In order to prevent insufficient driving force, a conveyor belt driving motor 19 is provided at the rotation of the conveyor belt 15.

[0029] Combination Figure 5 As shown, in a specific embodiment, a position sensor 24, a motor 27 and a roller 26 are provided at the exit of the auxiliary turning device 200. The position sensor 24 is used to detect the real-time position of the spray-bonded cotton and transmit the signal to the motor 27. The motor 27 drives the roller 26 to move and press the spray-bonded cotton onto the conveyor belt 15. Furthermore, limit baffles 25 are provided on both sides of the roller 26. The position of the spray-bonded cotton is adjusted by setting the limit baffles 25 so that it can accurately enter the next drying process.

[0030] The working process of the entire spray-bonded cotton oven is described below so as to further clearly demonstrate the function of the auxiliary turning device of the multi-layer continuous conveyor of the present invention:

[0031] When the spray-bonded cotton drying oven works normally, the heating box 300 is preheated first, and the heating rod 14 heats the air, and then the dry hot air is blown to the conveyor belt 15 through the upper air vent plate 12 under the action of the fan 13. The spray-bonded cotton is placed on the first layer of the conveyor belt 15, and the cloth conveying motor 18 drives the sprocket group to rotate, wherein the upper synchronous sprocket group 21 is used to drive the pressing roller 16 and the feeding roller 17, and the lower sprocket 20 is used for the rotation of the conveyor belt 15. The spray-bonded cotton is squeezed into the box 100 with a speed difference under the pressure of the pressing roller 16 and the feeding roller 17 and the support of the conveyor belt 15 for drying. After entering the box 100, the cotton embryo is first sprayed with glue, and the glue spray nozzle 22 sprays a mist of glue to evenly cover the surface of the cotton embryo with glue. After the glue spraying process is completed, the glue spraying cotton moves to the bottom of the preheated upper air venting plate 12 through the conveyor belt 15, and starts the first drying of the glue spraying cotton. Part of the hot air blown out returns to the heating box 300 through the lower air venting plate 23 for the subsequent drying process. In order to prevent insufficient driving force, a conveyor belt driving motor 19 is set at the turning point of the conveyor belt 15. The glue spraying cotton that has completed the initial drying enters the entrance of the auxiliary turning device 200 through the transition plate 28. After the transition roller 6, the glue spraying cotton slides into the auxiliary turning device 200 and starts to move along the arc guide groove to achieve turning. Since the glue spraying cotton may appear wrinkles when moving along the arc guide groove, when the glue spraying cotton moves to the telescopic plate 8, if wrinkles appear and affect the movement of the glue spraying cotton, the electric cylinder 9 can be used to drive the movable plate 202 of the upper transition plate 2 to swing up and down through the push rod 10 and the single ear sleeve 11, so that the telescopic plate 8 is stretched or compressed, and the wrinkles of the glue spraying cotton are removed, thereby ensuring the accurate turning effect of the glue spraying cotton. When the glue-spraying cotton runs to the exit of the auxiliary flipping device 200, the real-time position of the glue-spraying cotton is detected by the position sensor 24. When the glue-spraying cotton is about to reach the exit position, the position sensor 24 gives a signal, so that the motor 27 drives the roller 26 to move, presses the glue-spraying cotton onto the conveyor belt 15, and adjusts the position of the glue-spraying cotton under the action of the limit baffle 25, so that it can accurately enter the next drying process and achieve a good drying effect. After the flipping is completed, the glue-spraying cotton enters the conveyor belt 15 of the next layer of the box 100, and completes the production requirements of the finished product through feeding, secondary glue spraying, drying, and flipping. The drying process of the second and third layers is the same as that of the first layer. Since the glue-spraying cotton needs to be double-sided glue spraying, glue spray nozzles 22 are arranged in the first and second layers of the box 100, and auxiliary flipping devices 200 are arranged at the transition between the first and second layers and at the transition between the second and third layers.
