As a preferred embodiment of the present invention, as shown in fig. 3 to 5, the heating type hot air duct 100 includes a hot air duct body 102 and a cyclone air inlet unit, wherein the cyclone air inlet unit is constructed on a circumferential surface of the hot air duct body 102 near the elastic material guiding device 400, and hot air enters the hot air duct body 102 through the cyclone air inlet unit, and then flows in a spiral shape in a reverse direction of a conveying direction of the pole piece 600. The specific structure of the cyclone air inlet unit in this embodiment is that the cyclone air inlet unit includes an air inlet distribution set 107, a guide ring 106 and a plurality of inclined guide vanes 103, where the inclined guide vanes 103 are uniformly configured on the peripheral wall of the hot air drum body 102 along the circumferential direction of the hot air drum body 102, the guide ring 106 is configured on the inner wall of the hot air drum body 102, and the guide ring 106 is disposed at the inclined guide vanes 103. A diversion channel 104 is formed between adjacent inclined diversion blades 103 in the embodiment, and a swirl outlet nozzle 105 is formed between the inclined diversion blades 103 and the corresponding ends of the diversion ring 106, and the diversion channel 104 is mutually communicated with the corresponding swirl outlet nozzle 105. The air inlet distribution set 107 of the embodiment is sleeved outside the hot air cylinder, and each inclined guide vane 103 is ensured to be positioned in the air inlet distribution set 107, an air inlet joint 108 is constructed at the upper part of the air inlet distribution set 107, and the air inlet joint 108 is communicated with the air inlet distribution set 107; a first support leg 101 is formed at the lower portion of the inlet air distribution box 107. The working principle and the advantages of the embodiment are as follows: hot air enters the air inlet distribution group 107 through the air inlet joint 108, then enters each diversion channel 104 after being uniformly distributed through the air inlet distribution group 107, and under the action of the diversion ring 106, the hot air enters the hot air cylinder body 102 from each swirl outlet nozzle 105, and the hot air entering the hot air cylinder body 102 flows in a swirl manner along the reverse direction of the conveying direction of the pole piece 600, so that the twisted pole piece 600 is dried by the swirl hot air, on one hand, the dried moisture is conveniently and fully carried out of the hot air cylinder body 102, on the other hand, the heat exchange time between the swirl hot air and the pole piece 600 is prolonged compared with the direct-current hot air, the drying efficiency is improved, and on the other hand, the swirl hot air can sufficiently dry all areas of the twisted pole piece 600 (particularly the two sides of the pole piece 600 and the edges of the pole piece 600), and the problem of insufficient drying caused by the condition of dead angles is avoided.
As a preferred embodiment of the present invention, as shown in fig. 3 and 6-8, the adjustable deflector guide mechanism 200 includes an assembly sleeve 202 and two guide pair rollers 203, wherein two ends of the assembly sleeve 202 are respectively rotatably connected with ends of two adjacent heating air cylinders 100, the two guide pair rollers 203 are symmetrically disposed in the assembly sleeve 202, and two pole pieces 600 respectively pass through the assembly sleeve 202 after passing through the two guide pair rollers 203. The assembly sleeve 202 and the heating type heat dryer 100 of the present embodiment are specifically connected in such a manner that adapter rings 205 are respectively configured at two axial ends of the assembly sleeve 202, and each adapter ring 205 is rotatably assembled at the end of the corresponding heating type heat dryer 100. In order to facilitate the adjustment of the rotation angle of the assembly sleeve 202, the relative position of the assembly sleeve 202 and the heating type heat tunnel 100 can be effectively fixed, in this embodiment, first positioning flanges 206 are respectively configured at two axial ends of the assembly sleeve 202, second positioning flanges 109 are respectively configured at two axial ends of the heating type heat tunnel 100, and the first positioning flanges 206 are connected with the corresponding second positioning flanges 109 through a plurality of positioning bolts. The working principle and the advantages of the embodiment are as follows: in this embodiment, the angle of the two guide vane pairs 203 in the assembly sleeve 202 can be changed by rotating the angle of each assembly sleeve 202, so that the pole piece 600 in the adjustable double-vane drying device is in a twisted, spirally extended or horizontal form, and the pole piece 600 is generally not in a horizontal form and passes through the adjustable double-vane drying device, so that the drying effect is relatively poor in this form. After the assembly set 202 is adjusted, the first positioning flange 206 and the second positioning flange 109 are connected and fixed by positioning bolts. The embodiment adopts the rotation angle of the adjusting assembly kit 202 to adjust the shape of the pole piece 600 in the adjustable double-piece drying device, so that the length of a drying assembly line is effectively shortened on the premise of fully drying, and further, the occupation of a larger space is avoided.
As a preferred embodiment of the present invention, as shown in fig. 6 to 7, a plurality of wind-disturbing protrusions 204 are uniformly formed on the inner wall of the fitting sleeve 202 along the circumferential direction thereof, and a wind outlet 207 communicating with the outside is formed in each wind-disturbing protrusion 204. And in this embodiment, a wind collecting sleeve 208 is rotatably sleeved outside the assembling sleeve 202, an air outlet pipe 209 on the wind collecting sleeve 208 is communicated with the inner cavity of the assembling sleeve 202 through an air outlet hole 207, and a second supporting leg 201 is configured at the lower end of the wind collecting sleeve 208. The working principle and the advantages of the embodiment are as follows: after encountering the wind disturbing protrusion 204, part of the swirling hot wind flowing in the hot wind barrel body 102 is blocked by the wind disturbing protrusion 204 to form divergent air waves and turbulent cyclones, and the air waves and cyclones are in omnibearing contact with the twisted pole piece 600 at the corresponding position, and the twisted position of the pole piece 600 is fully dried. However, the swirling hot air in the hot air cylinder body 102 has a certain loss, so that the drying effect on the rear pole piece 600 is affected, and therefore, the swirling air inlet units on each hot air cylinder body 102 of the embodiment are all filled with hot air, so that the dissipated wind energy is supplemented, the swirling hot air in the hot air cylinder is enhanced to a certain extent, and meanwhile, the heat in each hot air cylinder body 102 is kept in a preset range, and the situation that the pole piece 600 cannot be dried sufficiently due to the fact that the heat in the hot air cylinder body 102 is lower than the preset range is avoided. In this embodiment, the two-sheet pole piece 600 in the adjustable two-sheet drying device is heated by the way of supplying hot air in sections, and the dried moisture enters the air collecting sleeve 208 through the air outlet 207 and is then discharged by the air collecting sleeve 208, so that the influence of continuous retention of water vapor in the adjustable two-sheet drying device on the drying effect is avoided.
