In this embodiment, through setting up dust removing mechanism 4, glass fine cloth is when passing through between two dust removal rollers 402, start third motor 405, under the transmission connection effect of second belt 404, two dust removal rollers 402 can rotate simultaneously, when dust removal roller 402 rotates, just can give the clean up to glass fine cloth surface's dust, start fan 407 simultaneously, can blow off glass fine cloth surface's dust, just so can guarantee that glass fine cloth's surface is in a dust-free environment, just can prevent that the dust from polluting PTFE material, thereby can improve the bonding efficiency of follow-up PTFE coating and glass fine cloth, the movable rod of electric telescopic handle 120 can drive slider 112 and slide in fixed plate 110's inside, just can adjust tensioning roller 113, thereby can adjust glass fine cloth's tensioning.
The application method and the working principle of the device are as follows: when the PTFE wear-resistant coating is used for coating glass fiber cloth on multi-section drying equipment, firstly, the glass fiber cloth on an unreeling roller 115 passes through a space between two dust removal rollers 402, then winds upwards from the bottom of a steering roller 211 at the front end of a drying box 101, then passes through a space between a supporting roller 204 and a coating roller 203, and then enters the drying box 101, firstly, is attached to a heat-conducting plate 103, then passes out of the other end of the drying box 101, passes through the top of a guide roller 111, then passes through a tensioning roller 113, then passes through the bottom of the steering roller 211, passes through a space between the supporting roller 204 and the coating roller 203, then enters the drying box 101, firstly, is attached to a heat-conducting plate 103, then passes out of the other end of the drying box 101, and finally winds on a winding roller 116, and the specific connection mode is shown in fig. 2; then, the first motor 119 is started, the unreeling roller 115 and the reeling roller 116 are driven to rotate under the transmission connection action of the first belt 118, so that glass fiber cloth can be driven to be conveyed, the third motor 405 is started, the two dedusting rollers 402 rotate simultaneously under the transmission connection action of the second belt 404, dust on the surface of the glass fiber cloth can be cleaned up while the dedusting rollers 402 rotate, and meanwhile, the fan 407 is started to blow off the dust on the surface of the glass fiber cloth, so that the surface of the glass fiber cloth is in a dust-free environment, the PTFE material can be prevented from being polluted by the dust, and the combination efficiency of the subsequent PTFE coating and the glass fiber cloth can be improved; the first pump 209 is then activated, drawing the PTFE coating in the coating tank 208 into the coating pan 207, at which time the second motor 206 is activated, under the meshing action of the gears 205, the pick-up roller 202 and the applicator roller 203 are driven to rotate, the pick-up roller 202 dips in the PTFE coating in the coating pan 207, then coating the glass fiber cloth on the coating roller 203, then coating PTFE coating on the surface of the glass fiber cloth by the coating roller 203, moving the glass fiber cloth coated with PTFE coating into the drying box 101, at the moment, starting the first heater 105 to heat the first copper pipe 104, the heat emitted by the first copper pipe 104 is conducted to the heat conducting plate 103, and the glass fiber cloth firstly passes through the heat conducting plate 103 when entering the drying box 101, the heat emitted by the heat conducting plate 103 can dry the glass fiber cloth, so that the non-combined moisture in the PTFE coated on the surface of the glass fiber cloth can be quickly evaporated, this allows the PTFE coating to solidify on the surface of the fiberglass cloth, which, as it passes over the bottom of the fan 109, when the second heater 107 is started, the second copper pipe 106 is heated by the second heater 107, the fan 109 blows the heat emitted by the second copper pipe 106 downwards, the drying rate of the PTFE coating on the surface of the glass fiber cloth can be increased, at this time, the PTFE coating is solidified and has no fluidity, so the hot air can not blow the PTFE coating, the coating is more uniformly distributed, when the PTFE coating on the surface layer is completely solidified, the glass fiber cloth downwards passes through another coating mechanism 2 to coat the other surface of the glass fiber cloth, then the PTFE coating is reversely conveyed from the inside of the drying box 101, and the drying method is consistent with the method, so that the coating and drying operation of the PTFE coating can be simultaneously carried out on the two sides of the glass fiber cloth, and the coating efficiency of PTFE is improved; then, the exhaust fan 307 is started to pump the non-combined moisture evaporated by PTFE into the purifying box 301 through the air pipe 306, at this time, warm steam is contacted with the ice-cooled cooling pipe 304 and the cooling fins 305, the steam is condensed into water drops on the surfaces of the cooling fins 305, the water drops drop downwards under the action of gravity and finally enter the waste liquid box 309 to be uniformly collected, the effect of waste gas recovery is realized, toxic components in the non-combined moisture are prevented from being emitted into the air, the second pump 303 is started to pump condensed water in the water tank 302 into the cooling pipe 304 and then flow back into the water tank 302, so that a circulation is formed, the heat dissipation rate of the cooling pipe 304 can be increased, and the condensation efficiency of the water drops is improved; because this device is layered structure, when guaranteeing to carry out multistage stoving to the fine cloth of glass, can also make the volume of this device can not be too big to can reduce the area of device, in sum just solved the problem that proposes in the above-mentioned background.
