DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 5In an embodiment of the utility model, an oil-proof paper drying device includes a conveying mechanism 100, and the conveying mechanism 100 includes a frame 110. Four supporting legs 111 are symmetrically fixed to the bottom surface of the frame 110. An electric conveyor belt 120 is rotatably connected between the two side walls of the frame 110. A motor 121 is fixedly connected to an outer wall of one side of the frame 110. The motor shaft of the motor 121 is transmission-connected to the roller in the electric conveyor belt 120. A flattening mechanism 200 is fixedly connected to the top surface of the frame 110. A hot air distribution mechanism 300 is fixedly connected to the top surface of the frame 110 at a position behind the flattening mechanism 200.

[0024] Specifically, the four mutually symmetrical supporting legs 111 on the bottom surface of the frame 110 provide stable support for the equipment, and the oil-proof paper to be dried is laid on the electric conveyor belt 120. The motor shaft of the driving motor 121 is transmitted to the roller inside the electric conveyor belt 120, so that the electric conveyor belt 120 drives the oil-proof paper to be transported forward. The flattening mechanism 200 is used to gently contact the surface of the oil-proof paper to prevent the oil-proof paper from deflecting or curling during transportation, which affects the drying effect.

[0027] In this embodiment, the hot air blower 400 is started so that the hot air generated by its internal heating element enters the hot air distribution box 320 through the hot air pipe 324 and is finally ejected from the air outlet pipe 321 to dry the oil-proof paper. The hot air distribution box 320 is a closed box. The hot air distribution box 320 is made of a material with good heat insulation performance to reduce heat loss. A solenoid valve 322 is installed on the outer wall of the air outlet pipe 321. By adjusting the solenoid valve 322, the hot air flow and wind speed of each air outlet pipe 321 can be controlled.

[0029] In specific implementation, the number of angle adjustment modules 340 can be changed as needed, and a plurality of sliding sleeves 341 are slidably sleeved on the outer wall of the slide rail 311, and the top end of the hot air nozzle 330 and the bottom end of the air outlet pipe 321 are connected through the bellows 323. The position of the sliding sleeve 341 can be adjusted according to the thickness and size of different types of oil-proof paper. When adjustment is required, first hold the handle 351 to lift the round rod 350 upward so that the tooth block 352 does not mesh with the rack 312. At this time, the sliding sleeve 341 can slide freely on the slide rail 311. After adjusting to a suitable position, release the handle 351. 51, the round rod 350 will move downward under the rebound action of the reset spring 353, so that the tooth block 352 will mesh with the rack 312 again, preventing the sliding sleeve 341 from causing the hot air nozzle 330 to deviate during the drying process; the motor shaft of the driving motor three 344 is transmitted to the rotating shaft one, so that the gear one 343 and the gear two 345 are meshed and transmitted, so that the fixing ring 347 drives the hot air nozzle 330 to rotate, and the spray angle of the hot air nozzle 330 is changed, which is convenient for the operator to adjust, and ensure that the hot air can cover the entire surface of the oil-proof paper to avoid the problem of uneven drying.

[0030] Embodiment 2

[0031] like Figure 3 As shown, in this embodiment, the flattening mechanism 200 includes a screw rod 210, both ends of the screw rod 210 are fixedly connected to side frames 211, a side wall of one of the side frames 211 is fixedly connected to a second motor 213, the motor shaft of the second motor 213 is transmission-connected to one end of the screw rod 210, the bottom surface of the side frame 211 is fixedly connected to the top surface of the frame 110, the left and right ends of the screw rod 210 have opposite screw threads, the left and right ends of the screw rod 210 have two transmission blocks 220 symmetrically screwed together on the outer walls, the bottom surfaces of the two transmission blocks 220 are fixedly connected to electric telescopic rods 221, the bottom ends of the two electric telescopic rods 221 are fixedly connected to a pressing block 230, an anti-rotation rod 212 is fixedly connected between the two side frames 211, and the anti-rotation rod 212 is slidably connected to the two transmission blocks 220. The bottom surfaces of the two pressing blocks 230 are both rotationally connected to a plurality of rollers 231.

[0032] In specific implementation, when the oil-proof paper is transported on the electric conveyor belt 120, the motor shaft of the second driving motor 213 is transmitted to the screw rod 210 according to the width of the oil-proof paper, so that the two transmission blocks 220 move toward or away from each other and are adjusted to a width suitable for the oil-proof paper, and the two electric telescopic rods 221 are driven to extend, so that the two pressing blocks 230 extend downward until the roller 231 contacts the surface of the oil-proof paper. The rotating roller 231 reduces the friction between the pressing block 230 and the oil-proof paper, which can not only restrict the oil-proof paper between the electric conveyor belt 120 and the pressing block 230 to prevent the oil-proof paper from rolling up, but also prevent the friction between the pressing block 230 and the oil-proof paper from being too large to hinder the transportation of the oil-proof paper.
