[0003] In fabric production, hot melt adhesive is used as the compounding material according to the type of fabric. Hot melt adhesive needs a certain time for heating and curing. If only the compounding mechanism is used for heating, the compounding efficiency of the fabric is relatively low. SUMMARY

The fabric is compounded at the compounding mechanism.

[0005] The double-pressing device comprises a rack, a large pressing roller is arranged in the middle of the rack, a plurality of third air cylinders are arranged on the outer side of the large pressing roller, a small pressing roller is arranged at the output end of the third air cylinder, and a driving motor for driving the large pressing roller to rotate is arranged on the rack. Since hot melt adhesive is used for fabric compounding, the hot melt adhesive needs to be fully heated and cured. If only the compounding mechanism is used, a longer time is needed for heating, and the efficiency is relatively low. If the hot melt adhesive is not heated enough, wrinkles, orange peel patterns and cracks of the fabric are easily caused during the compounding process. Therefore, the double-pressing device is arranged, the fabric passes around the large pressing roller, and the small pressing roller is attached to the large pressing roller and extrudes the fabric under the action of the third air cylinder, realizing the function of re-compounding the fabric. If the residual heat is insufficient, relevant electric heating elements need to be arranged in the large pressing roller or the small pressing roller.

[0006] Preferably, a first unwinding mechanism is arranged at the lower part of one end of the support structure, one side of the first unwinding mechanism is provided with an upper conveying belt, and the upper conveying belt is located on the upper layer of the support mechanism. The first unwinding mechanism releases the fabric, and the upper conveying belt provides a stacking position of the fabric, so that there is sufficient fabric on the production line to provide operation time for the first unwinding mechanism to feed again.

[0007] Preferably, a second unwinding mechanism is arranged at the lower part of the support structure, and a lower conveying belt is arranged on one side of the second unwinding mechanism. Similarly, the lower conveying belt and the upper conveying belt have the same function, and in addition, the lower conveying belt and the upper conveying belt are arranged in an up-down position, which is beneficial to fully utilize the vertical space and shorten the length of the production line.

[0008] Preferably, one side of the re-pressing device is provided with a storage rack, and one side of the storage rack is provided with a winding mechanism. The storage rack is used for storing the composite fabric. If the winding mechanism is wound again, the storage rack provides a time window for the winding mechanism to be wound again.

[0009] Preferably, the upper end of the support structure is fixedly connected with a first air cylinder, and the output end of the first air cylinder is provided with two first roller members arranged side by side. The fabric sent out from the first unwinding mechanism passes through the first roller members in an S shape. When the first air cylinder acts, the first roller members are lifted and lowered, so as to pull the fabric.

[0010] Preferably, one side of the first air cylinder is provided with a second air cylinder, the output end of the second air cylinder is rotatably connected with a connecting rod, the middle part of the connecting rod is rotatably connected to the support structure, one end of the connecting rod is provided with a second roller member, and the other end of the connecting rod is fixedly connected with a counterweight. The fabric passing through the first roller members passes through the second roller members again, and the counterweight connected with the connecting rod and the second air cylinder adjust the second roller members, so as to ensure the tension of the fabric.

[0011] The beneficial effects of the present application are as follows:

[0012] 1. The re-pressing device is arranged, the composite mechanism is operated, and the composite device is re-rolled, which is beneficial to improve the composite efficiency of the fabric and ensure the quality of the composite.
