Detailed implementation manners

[0025] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given in conjunction with the accompanying drawings of the specification.

[0026] Embodiment 1

[0027] Referring to Figures 1-4 , which is the first embodiment of the present utility model, a dryer for bamboo papermaking is provided. This dryer for bamboo papermaking includes a drying box 1. Through holes are provided on both symmetric sides of the drying box 1. A plurality of conveyor rollers 2 are rotatably connected inside the drying box 1. Heating plates 3 are installed on both the upper and lower sides inside the drying box 1. An air supply mechanism 4 is provided on one side between the two heating plates 3.

[0028] In the above technical solution, a conveyor motor is installed on one side of the drying box 1. The conveyor motor is used to drive the plurality of conveyor rollers 2 to rotate synchronously. After the paper enters the drying box 1 through one through hole, the conveyor rollers 2 drive the paper to move slowly. The heating plates 3 heat the air inside the drying box 1, and the air supply mechanism 4 drives the hot air to flow, so that the hot air effectively contacts both sides of the paper to dry and dehumidify the paper.

[0029] The air supply mechanism 4 includes a rotating shaft 402 driven by a motor 401, and a plurality of fan blades 405 are transmission-connected to the rotating shaft 402. The air supply mechanism 4 also includes a plurality of air guide plates 406 rotatably connected to the heating plate 3, and a driving plate 407 is slidingly fitted on the rotating shaft 402, and the driving plate 407 is used to drive the air guide plates 406 to swing.

[0030] In the above technical solution, the motor 401 is fixedly installed on one side of the drying box 1, and the rotating shaft 402 is rotatably connected to the drying box 1. The fan blades 405 are arranged on one side of the conveying roller 2. The rotating shaft 402 drives multiple fan blades 405 to rotate synchronously, so that the fan blades 405 can drive the hot air to flow, so that the hot air can effectively contact the paper. At the same time, the rotating shaft 402 drives the driving plate 407 to move back and forth, and the driving plate 407 drives the air guide plate 406 to swing back and forth, so that the flow direction of the hot air can be changed, ensuring that the hot air can effectively contact all parts of the paper.

[0031] A plurality of bevel gears 1 403 are fixedly connected at equal intervals on the rotating shaft 402, and a bevel gear 2 404 is coaxially connected to the fan blade 405. The bevel gear 1 403 is meshed with the bevel gear 2 404, and the fan blade 405 is rotatably connected to the drying box 1 through a connecting frame. The bevel gear 1 403 is meshed with the bevel gear 2 404 so that when the rotating shaft 402 rotates, the fan blades 405 are driven to rotate synchronously at a low speed to avoid force deviation of the paper due to excessive wind speed.

[0032] The driving plate 407 is slidably connected to the drying box 1 , and a through hole is opened in the middle of the driving plate 407 . A cam 408 is fixedly connected to the rotating shaft 402 , and the cam 408 is in slidable contact with the driving plate 407 .

[0033] In the above technical solution, both ends of the driving plate 407 are horizontally slidably connected to the limit rod, one end of the limit rod is fixedly connected to the inner wall of the drying box 1, and the protruding end of the cam 408 contacts the driving plate 407 to make the driving plate 407 slide to one side. The cam 408 rotates one circle to make the driving plate 407 perform a horizontal reciprocating motion once, so that the driving plate 407 drives the air guide plate 406 to swing back and forth.

[0034] Both ends of the driving plate 407 are slidably connected with pull rods 409, and the pull rods 409 are rotatably connected to the air guide plate 406. When the driving plate 407 moves, the air guide plate 406 is driven to move through the pull rods 409. One end of the pull rod 409 is slidably connected to a limiting hole provided on the driving plate 407, so that when the air guide plate 406 swings, it will drive the pull rod 409 to rise or fall horizontally, and the pull rod 409 cooperates with the limiting hole to avoid movement interference.

[0035] A guide plate 5 is provided on one side of the drying box 1 away from the air supply mechanism 4, and the guide plate 5 is in a semicircular structure.

[0036] In the above technical solution, when the hot air moves from one end of the fan blade 405 to the side of the guide plate 5, the inner groove of the guide plate 5 guides the hot air, so that the hot air passes through the other side of the heating plate 3 and finally returns to the side of the fan blade 405. Moreover, the hot air can be heated again when moving on the other side of the heating plate 3, avoiding the decrease in the temperature of the hot air.

[0037] During use, after the paper enters the drying box 1 through a through hole, the conveying motor drives a plurality of conveying rollers 2 to rotate synchronously. The conveying rollers 2 drive the paper to move slowly. The heating plate 3 heats the air in the drying box 1. The motor 401 drives the rotating shaft 402 to rotate. The first bevel gear 403 meshes with the second bevel gear 404, so that when the rotating shaft 402 rotates, it drives each fan blade 405 to rotate synchronously at a low speed. The fan blade 405 drives the hot air to flow, enabling the hot air to effectively contact both sides of the paper. At the same time, the cam 408 rotates to drive the driving plate 407 to reciprocate. The driving plate 407 cooperates with the pull rod 409 to drive the air guide plate 406 to swing, thereby changing the flow direction of the hot air and making it fully contact the paper.

[0038] When the hot air moves near the guide plate 5, the inner groove of the guide plate 5 guides the hot air, so that the hot air passes through the other side of the heating plate 3 and finally returns to the side of the fan blade 405. Moreover, the hot air can be heated again when moving on the other side of the heating plate 3, causing the hot air to reciprocate along the loop-shaped channel and effectively drying the paper.

[0039] Embodiment 2

[0040] Referring to Figure 5 , this is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a dehumidification component 6 is provided on one side of the heating plate 3. The dehumidification component 6 includes a water collection tank 601. A plurality of dehumidification plates 602 are provided on the upper side of the water collection tank 601. One end of the water collection tank 601 is fixedly connected with a drain pipe 603, and the drain pipe 603 passes through the drying box 1 and extends to the outside.

[0041] In the above technical solution, two dehumidification components 6 are respectively arranged on the top surface of the upper heating plate 3 and the inner bottom surface of the drying box 1, and are arranged on the side close to the guide plate 5. The water collection tank 601 and the dehumidification plates 602 are both fixedly connected to the inner wall of the drying box 1. When the hot air passes through the dehumidification plates 602, the moisture can adhere to the dehumidification plates 602 and condense into water droplets and fall into the water collection tank 601, and finally the water is discharged from the drying box 1 through the drain pipe 603, thereby ensuring the air drying quality in the drying box 1 and reducing energy consumption.

[0042] The remaining structures are the same as those in Embodiment 1.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
