At this time, the base material is conveyed to the gluing component through the base material conveying component. After the base material is glued, the base material passes through the first silicone pressure roller 13. The base material and the outer material are tightly bonded by the extrusion between the first silicone pressure roller 13 and the large drying cylinder 17, and then the bonded fabric is again extruded between the second silicone pressure roller 14 and the large drying cylinder 17.

The straight texture cutter and the pattern texture cutter are both conventional existing technologies in the field and can be directly installed on the present device for use.

[0030] like Figures 1 to 8 As shown, the top of the frame body 1 is rotatably connected to the first preheating roller 3 and the fourth silicone pressure roller 31; the first preheating roller 3 and the fourth silicone pressure roller 31 are located between the second cloth guide roller 112 and the third cloth guide roller 12; the end of the frame body 1 close to the base material inlet 27 is rotatably connected to the fifth silicone pressure roller 33 and the second preheating roller 32; the fifth silicone pressure roller 33 and the second preheating roller 32 are located between the second oil pressure opposite edge assembly 28 and the straight blade holder 24. When working, the first preheating roller 3 and the second preheating roller 32 are respectively arranged in the forward direction of the fabric and the base material, so that the fabric and the base material can be heated in advance, so that when the fabric and the base material are squeezed and bonded at the position of the third cloth guide roller 12, the glue is easier to spread, so that the glue can more easily bond the fabric and the base material.

[0031] like Figures 1 to 8As shown, the middle part of the frame body 1 is rotatably connected with the first cold water roller 4 and the sixth silicone pressure roller 41; the first cold water roller 4 and the sixth silicone pressure roller 41 are located between the cloth clamping roller assembly 19 and the sixth cloth guide roller 18; the middle part of the frame body 1 is rotatably connected with the second cold water roller 52; the second cold water roller 52 is located below the first cold water roller 4. When working, by arranging the first cold water roller 4 and the second cold water roller 52 on the frame body 1, the cloth can bypass the surfaces of the first cold water roller 4 and the second cold water roller 52 after extrusion and forming, so that the first cold water roller 4 and the second cold water roller 52 cool the extruded and bonded cloth, so that the glue can coagulate quickly, thereby increasing the integrity and quality of the cloth.

[0033] like Figures 1 to 8 As shown, a drying box 6 is fixedly connected to the top of the frame body 1; the drying box 6 is arranged between the large drying cylinder 17 and the third silicone pressure roller 23. When working, the drying box 6 is arranged on the frame body 1, so that when the base material after gluing passes through the drying box 6, the drying box 6 semi-dries the glue on the surface of the base material, so that the glue is in a solid-liquid mixed state, reducing the possibility of liquid glue dripping from the surface of the base material during the transportation process of the base material, and at the same time making the pattern shape stable, reducing the possibility of deviation of the pattern when the glue is bonded.

[0034] like Figures 1 to 8 As shown, a protective plate 7 is fixedly connected to the bottom of the frame body 1; the protective plate 7 is located above the fourth cloth guide roller 15 and the fifth cloth guide roller 16, and is arranged below the large drying drum 17; the protective plate 7 is arranged in an arc shape.

At this time, the base material is conveyed to the gluing assembly through the base material conveying assembly. After the base material is glued, the base material passes between the first silicone pressure roller 13 and the large drying cylinder 17. Through the extrusion between the first silicone pressure roller 13 and the large drying cylinder 17, the base material and the fabric are tightly bonded. Then, the bonded fabric passes between the second silicone pressure roller 14 and the large drying cylinder 17 for secondary extrusion. At this time, the extruded fabric passes through the fourth cloth guide roller 15, the fifth cloth guide roller 16, the sixth cloth guide roller 18 and the cloth clamping roller assembly 19 in sequence, and finally the fabric is wound and gathered by the winding assembly 101. By making the gluing and extrusion happen at the same time, the operation steps are reduced, making the processing more convenient and quick.

[0036] By installing a straight texture cutter above the eighth cloth guide roller 25 and a pattern texture cutter above the glue roller 22, when it is necessary to produce straight striped fabric, the base material passes through the eighth cloth guide roller 25, so that the straight texture cutter prints glue on the base material, and then it is extruded and bonded with the fabric at the large drying cylinder 17. When it is necessary to produce patterned striped fabric, the base material passes through the glue roller 22 and the third silicone pressure roller 23, so that the pattern texture cutter prints glue on the base material, and then the base material and the fabric are extruded and formed through the large drying cylinder 17. By respectively arranging the eighth cloth guide roller 25 and the third silicone pressure roller 23 on the frame body 1, the fabric can be straight-shaped or pattern-shaped, making the production more convenient and quick, without the need to frequently replace the corresponding pressure rollers and cutters during production, thereby increasing the production quality and speed of the fabric. The straight texture cutter and the pattern texture cutter are both conventional existing technologies in the field and can be directly installed on the device for use.

[0037] By respectively arranging the first preheating roller 3 and the second preheating roller 32 in the forward direction of the fabric and the base material, the fabric and the base material can be heated in advance, so that when the fabric and the base material are squeezed and bonded at the position of the third cloth guide roller 12, the glue is easier to spread, making it easier for the glue to bond the fabric and the base material.

[0038] By arranging the first cold water roller 4 and the second cold water roller 52 on the frame body 1, the cloth can be passed around the surfaces of the first cold water roller 4 and the second cold water roller 52 after the cloth is extruded and formed, so that the first cold water roller 4 and the second cold water roller 52 can cool the cloth after extrusion and bonding, so that the glue can coagulate quickly, thereby increasing the integrity and quality of the cloth.

[0039] By providing the first transmission gear 51 and the second transmission gear 53 between the second cold water roller 52 and the first cold water roller 4, the first cold water roller 4 and the second cold water roller 52 can be driven to rotate simultaneously by a single driving motor, thereby reducing equipment costs.

[0040] By providing a drying box 6 on the frame body 1, the drying box 6 semi-dries the glue on the surface of the base material after gluing when the base material passes through the drying box 6, so that the glue is in a solid-liquid mixed state, reducing the possibility of liquid glue dripping from the surface of the base material during the transportation of the base material, and at the same time making the pattern shape stable, reducing the possibility of deviation of the pattern when the glue is bonded.

[0041] By providing a protective plate 7 under the large drying drum 17, after the fabric is extruded and formed, the fabric adhered to the surface of the large drying drum 17 can be conveyed to reduce the residual glue on the fabric dripping onto the portion being conveyed under the large drying drum 17, thereby improving the safety of the fabric production process.
