when the composite roller 32 works, the closing plate 324 in the installation cavity 322 in the composite roller 32 is gradually close to the composite platform 31, the attraction between the closing plate 324 and the composite platform 31 is gradually increased, when the distance between the closing plate 324 and the composite platform 31 is reduced to a certain degree, the attraction between the closing plate 324 and the composite platform is larger than the elastic force of the first spring 323, so that the closing plate 324 moves, an inlet of the micropore 321 into the installation cavity 322 is opened, the micropore 321 is re-penetrated, hot air entering the composite roller 32 can be sprayed out of the micropore 321, the fabric is pre-dried, meanwhile, when the closing plate 324 in the installation cavity 322 in the composite roller 32 is gradually far away from the composite platform 31 along with the operation of the composite roller 32, the attraction between the closing plate 324 and the composite platform 31 is gradually reduced, when the elastic force of the first spring 323 is larger than the attraction between the closing plate 324 and the original position, the inlet of the micropore 321 into the installation cavity 322 is closed again, the hot air can not be sprayed out, the phenomenon that the hot air is blown and lost randomly to cause heat loss is avoided, and meanwhile, the phenomenon that the adhesive on the fabric begins to cure in advance to influence the fabric compounding effect due to the fact that the hot air blows the fabric which is not compounded by the compound roller 32 in front of the compound roller 32 is avoided.
The specific working process is as follows:
during operation, the prepared lining fabric and the surface fabric are respectively placed on a first material roll 11 and a second material roll 12, the lining fabric on the first material roll 11 passes through a first coating roll 21, a layer of adhesive is coated on the lining fabric through the first coating roll 21, meanwhile, the surface fabric on the second material roll 12 passes through a second coating roll 22, a layer of adhesive is coated on the surface fabric through the second coating roll 22, then the surface fabric and the lining fabric which are coated with the adhesive reach a compounding mechanism, the surface fabric and the lining fabric are bonded together through the compounding mechanism, then the fabric which is compounded leaves the compounding mechanism and enters a drying box 41, the fabric which enters the drying box 41 is dried in the drying box 41, and then the dried fabric reaches a material collecting roll 51 and is collected; when the inner layer fabric and the surface layer fabric are coated with the adhesive through the first coating roller 21 and the second coating roller 22 respectively, the external adhesive is input into the first coating roller 21 and the second coating roller 22 through the first pipeline 211 and the second pipeline 222, the adhesive enters the first coating roller 21 through the first pipeline 211 and then enters the coating hole 214 through the first cavity 212 in the first coating roller 21, then reaches the fabric from the coating hole 214 to complete the coating of the adhesive on the inner layer fabric, meanwhile, the closing rod 224 arranged in the second cavity 213 is attracted by the second magnet 225 and pulled out outwards along with the rotation of the first coating roller 21 when the magnetic block on the closing rod 224 is opposite to the second magnet block 225 arranged on the fixed frame 221, and after the closing rod 224 is pulled out, the through hole 325 on the closing rod 224 conducts the coating hole 214 to enable the adhesive to be coated through the coating hole 214, then, with the continuous rotation of the first coating roller 21, the magnetic block on the closing rod 224 is far away from the second magnet block 225 and gradually approaches to the first magnet block 223 until the magnetic block is opposite to the first magnet block 223, the closing rod 224 receives the repulsive force of the first magnet block 223, so that the closing rod 224 retracts into the second cavity 213, after the closing rod 224 returns to the second cavity 213, the through hole 325 on the closing rod 224 and the coating hole 214 are staggered with each other, so as to seal the coating hole 214, and as the first magnet block 223 and the second magnet block 225 are positioned at the contact point of the lining fabric and the first coating roller 21, the first coating roller 21 only sprays adhesive at the contact point of the lining fabric; after the adhesive is sprayed out from the coating holes 214, the first coating roller 21 is tightly attached to the inner fabric, the adhesive for spraying is rapidly expanded to two ends along the coating groove 215 under the action of the subsequent continuously sprayed adhesive after contacting the surface of the fabric, meanwhile, a space with a narrow middle part and wide two ends is relatively formed between the coating groove 215 and the fabric due to the protrusion at the bottom part in the coating groove 215, so that the adhesive is limited by the shape of the space after being sprayed out, the adhesive is rapidly sprayed out towards the two ends of the first coating roller 21 after filling the coating groove 215 after being sprayed out, and meanwhile, the brush rollers 216 on the two side walls of the coating groove 215 push the adhesive coated on the fabric to the edge area of the fabric in the movement process of the brush rollers 216 due to the fusiform of the brush rollers 216; when the inner layer fabric and the surface layer fabric pass through the first coating roller 21 and the second coating roller 22, the edges of the fabrics are extruded and fixed by the conical ring 23 and the extrusion rollers, meanwhile, the steps between the conical ring 23 and the extrusion rollers 24 can form a shearing effect relatively, and when the fabrics are coated with the adhesive, the redundant adhesive protruding out of the edges of the fabrics can be removed; when the inner layer fabric and the surface layer fabric coated with the adhesive reach a composite mechanism, the fabric penetrates through a gap between the composite roller 32 and the composite platform 31, the composite roller 32 extrudes and composites the two layers of fabrics, meanwhile, because the rotating shafts of the first coating roller 21 and the second coating roller 22 are provided with the cam 25, the tail end of the pushing frame 35 arranged on the rotating shaft of the composite roller 32 is contacted with the cam 25, in the rotating process of the first coating roller 21 and the second coating roller 22, the pushing frame 35 is displaced under the action of the cam 25, so that the composite roller 32 is driven to move in the sliding seat 33, the composite roller 32 is caused to displace relative to the composite platform 31, meanwhile, because the second spring 323 is arranged in the sliding seat 33, under the action of the second spring 323, the composite roller 32 can rapidly return to the original position after being displaced under the action of the pushing frame 35, so as to reciprocate in the rotating process of the cam 25, in the reciprocating process of the composite roller 32, the compound roller 32 is displaced relative to the fabric; after the fabric is compounded by the compounding mechanism, the fabric enters the drying box 41 to be dried, the solidification of the adhesive on the fabric is accelerated, a large amount of heat is generated in the drying process of the drying box 41, excessive heat in the drying box 41 is discharged through the air outlet, meanwhile, the discharged hot air is conveyed by a pipeline and enters the through holes 325 on the compounding rollers 32, the hot air entering the through holes 325 is sprayed out of the micropores 321 due to the fact that the through holes 325 are communicated with the micropores 321, the sprayed hot air contacts the fabric tightly attached to the surfaces of the compounding rollers 32, and the fabric is pre-dried through the heat carried in the hot air; as the composite roll 32 is run, the closing plate 324 in the mounting cavity 322 in the composite roll 32 gradually approaches the composite platform 31, the attractive force between the closing plate 324 and the composite platform 31 gradually increases, when the distance between the two is reduced to a certain degree, the attraction force between the two is larger than the elastic force of the first spring 323, thereby moving the closing plate 324, opening the inlet of the micropore 321 into the installation cavity 322, making the micropore 321 run through again, the hot air entering the composite roller 32 can be sprayed out from the micropore 321, meanwhile, as the closing plate 324 in the installation cavity 322 in the composite roll 32 is gradually moved away from the composite platform 31 as the composite roll 32 is operated, the attraction force between the closing plate 324 and the composite platform 31 is gradually reduced, when the elastic force of the first spring 323 is greater than the attractive force between the first spring and the second spring, the sealing plate 324 returns to the original position to seal the inlet of the micro-hole 321 into the mounting cavity 322 again, so that hot air cannot be sprayed out.
