In the pre-order stage of interlining processing, it is necessary to unwind the interlining. In order to make the unwound interlining smooth, it is necessary to use multiple parallel shafts with different positions and heights to wind the interlining on it, and then turn the interlining out. When the wind enters from the inside, it will drive the interlining to flutter, causing the interlining to wrinkle. At the same time, the fluttering of the interlining will greatly reduce the speed of unwinding the interlining, so that the interlining between the rotating shafts cannot be tightened.
[0003] In the pre-order stage of interlining processing, it is necessary to unwind the interlining. When one roll of interlining is unloaded, the staff needs to put in another roll of interlining and rewind the head of the interlining roll to the rotating shaft for transmission. , and then follow-up operations can be continued, it is difficult to achieve continuous production, which reduces work efficiency and increases production costs
[0004] The existing oven uses heat transfer oil, that is, the heat transfer oil pipe is connected in the oven, and the heat transfer oil dissipates heat into the oven when passing through the heat transfer oil pipe in the oven, thereby realizing the drying of the interlining. The most important thing is that the heat conduction oil pipeline dissipates heat, and the heat dissipation is uneven, resulting in uneven drying of the interlining, which greatly affects the quality of the interlining
[0005] The movement of the interlining during the processing is realized by the rotation of the reel. During the rotation of the reel, the two ends of the reel rub against the fixing parts that fix the reel and generate a lot of heat. High heat creates a safety hazard to the operator and surrounding objects
[0006] After the drying is completed, the interlining needs to be inspected, and the situation of uneven addition of slurry and hot melt adhesive dry powder not sprayed on the slurry should be remedied in time, so as to improve the pass rate of the finished interlining, but there is no such thing as interlining inspection in the prior art. Steps, resulting in a large number of defects in the interlinings that have been sold in the market, bringing huge pressure on the after-sales of enterprises
[0007] When adding dot-shaped slurry on the interlining, a discharge roller with a discharge hole is required. The slurry is added to the inside of the discharge roller, and the discharge roller is driven to rotate, so that the slurry is discharged from the discharge hole. The dot-shaped slurry is formed on the interlining cloth, but because the slurry is relatively thick, when the slurry is discharged, the gravity of the slurry alone cannot achieve uniform output from each outlet, which will easily lead to the adhesion of the interlining cloth. Not enough, affect the quality of the product
[0008] After the drying is completed, the interlining needs to be rewound. In the prior art, the motor drives the rotating shaft of the interlining to rewind, but the finished interlining obtained by winding in this way is loose and difficult to move and transport. The rolled interlining is heavy, and the interlining needs to be raised first to remove the interlining from the winding frame. The operation is time-consuming and laborious, which reduces the production efficiency of the enterprise
[0009] In addition, in the prior art, due to the fact that the hot melt adhesive dry powder cannot fully realize the one-to-one bonding with the point-shaped slurry, the finished interlining after drying often contains a large amount of redundant hot melt adhesive dry powder, which directly contains a large amount of hot melt adhesive powder. The interlining of hot melt adhesive dry powder is used in subsequent interlining production, it is difficult to guarantee the quality of the product, and it causes a great waste of hot melt adhesive dry powder
[0010] Many of the above problems lead to low production efficiency of garment double-point interlining, low product quality and high cost

Description
technical field [0001] The invention relates to the field of interlining processing, in particular to the improvement of the structure of a double-point coating production line for hot-melt adhesive interlining. Background technique [0002] The main process of garment interlining processing is to add dotted slurry on the interlining and spray hot melt adhesive dry powder on the dotted slurry, and then dry the interlining. In the pre-order stage of interlining processing, it is necessary to unwind the interlining. In order to make the unwound interlining smooth, it is necessary to use multiple parallel shafts with different positions and heights to wind the interlining on it, and then turn the interlining out. When the wind enters from the inside, it will drive the interlining to flutter, causing the interlining to wrinkle. At the same time, the fluttering of the interlining will greatly reduce the speed of unwinding the interlining, so that the interlining between the rotat...
