[0002] Compared with general fabrics, plush fabrics have a lot of fluff on their surfaces. These fluff can improve the touch of the fabric and enhance the heat preservation performance of the fabric. After the dyeing treatment of plush fabrics, drying and shaping are required. The drying and shaping of traditional fabrics use pressing rollers for extrusion dehydration or centrifugal dehydration. Extrusion dehydration is suitable for long strip-shaped fabrics for continuous production, and centrifugal dehydration is suitable for small sections of fabrics. However, no matter which of the above methods, it is easy to damage the fluff in the plush fabric during the dehydration process, resulting in fluff shedding, uneven distribution of fluff on the plush fabric, and affecting the quality of the product. Therefore, it is necessary to design a drying and shaping device for plush fabrics according to the characteristics of plush fabrics. Summary of the Invention

[0003] To solve the above technical problems, the technical solution adopted by the present invention is: a drying and shaping device for plush fabrics, including a water squeezing mechanism and a drying mechanism. The water squeezing mechanism includes a conical cylinder, which is provided with a large-diameter end and a small-diameter end. A number of extrusion roller groups are sequentially installed at the large-diameter end, inside the conical cylinder, and the small-diameter end. Each extrusion roller group includes a number of rotatable extrusion rollers connected to the conical cylinder. The extrusion rollers in each extrusion roller group are arranged in a circumferential array around the axis of the conical cylinder, and the extrusion rollers in adjacent two extrusion roller groups are staggered with each other. The drying mechanism includes a drying table and a drying box located on the drying table. A lower heating conveyor belt is installed on the drying table, and an upper heating conveyor belt is installed on the drying box. The lower heating conveyor belt and the upper heating conveyor belt have the same structure. Among them, a number of ventilation holes are evenly distributed on the lower heating conveyor belt. Negative pressure cavities are respectively arranged inside the drying table and the drying box. The ventilation holes communicate with the negative pressure cavities, and negative pressure is formed in the negative pressure cavities through a negative pressure fan. The lower heating conveyor belt and the upper heating conveyor belt are respectively heated by heating mechanisms.

The extrusion roller groups inside the conical cylinder and at both ends of the conical cylinder are used to perform a surrounding extrusion on the plush fabric to remove the water in the plush fabric.

[0013] Step 2, after the plush fabric leaves from the small-diameter end, it is spread out and enters between the drying table and the drying box in a flat state. The lower heating conveyor belt and the upper heating conveyor belt are used to heat the plush fabric, and the negative pressure formed by the negative pressure cavity is used to suck away the hot air formed by heating to realize the drying and shaping of the plush fabric.

[0021] As Figures 1-3 shown, a plush fabric drying and shaping device includes a water squeezing mechanism and a drying mechanism. The water squeezing mechanism includes a conical cylinder 1, on which a large-diameter end 2 and a small-diameter end 3 are provided.

A lower heating conveyor belt 10 is installed on the drying table 8, and an upper heating conveyor belt 11 is installed on the drying box 9. The lower heating conveyor belt 10 and the upper heating conveyor belt 11 have the same structure. Among them, a number of ventilation holes are evenly distributed on the lower heating conveyor belt 10. Negative pressure chambers 12 are respectively provided inside the drying table 8 and the drying box 9. The ventilation holes are communicated with the negative pressure chambers 12, and negative pressure is formed in the negative pressure chambers 12 through a negative pressure fan. The lower heating conveyor belt 10 and the upper heating conveyor belt 11 are respectively heated by a heating mechanism.

[0022] Further, each extrusion roller group 4 contains four extrusion rollers 7.

[0023] Furthermore, brackets are provided at both ends of the squeezing roller 7, and the two ends of the squeezing roller 7 are rotatably connected to the brackets, and the brackets are fixedly connected to the conical cylinder 1. Some squeezing rollers 7 are driven to rotate by a motor, and some squeezing rollers 7 are freely rotated.

[0024] Furthermore, the squeezing roller 7 includes a roller shaft 13 and a sleeve 14 sleeved on the roller shaft 13, and the outer diameter of the sleeve 14 gradually increases from the middle of the sleeve 14 to both ends of the sleeve 14. The squeezing rollers 7 in the same group of squeezing rollers 7 are surrounded in a ring to form an embracing squeezing of the plush fabric 19.

[0025] Furthermore, a water receiving box is provided below the conical tube 1. The water receiving box can receive water flowing out of the conical tube 1.

[0026] Furthermore, a plurality of conveying rollers 15 are sequentially arranged in front of the large-diameter end 2 of the conical cylinder 1, and a plurality of conveying rollers 15 are respectively arranged in front and in the rear of the drying mechanism.

[0027] Furthermore, the conveying roller 15 in front of the large-diameter end 2 of the conical cylinder 1 is a bending roller 16, and the conveying roller 15 between the drying mechanism and the conveying roller 15 and the conical cylinder 1 is a bending roller 16. The bending roller 16 has a certain bending amplitude, and can stretch the plush fabric 19 when rotating. The plush fabric 19 before entering the conical cylinder 1 is stretched by the bending roller 16, so that the flat state in the front can gradually transition to the retracted state in the back. The bending roller 16 between the conical cylinder 1 and the drying mechanism stretches the plush fabric 19 in the retracted state, so that it gradually transitions to the flat state. The bending amplitude of the bending roller 16 between the conical cylinder 1 and the drying mechanism should be large so that the plush fabric 19 can be fully unfolded. The bending rollers 16 are driven to rotate by motors respectively. The remaining straight conveying rollers 15 can be arranged in pairs, and some conveying rollers 15 are driven to rotate by motors.

[0028] Furthermore, the heating conveyor belt includes a heat-conducting rubber belt 17 and a plurality of heating rollers 18.

After dyeing treatment, the plush fabric 19 enters the conical cylinder 1 from the large-diameter end 2 of the conical cylinder 1 and leaves the conical cylinder 1 from the small-diameter end 3. The extrusion roller groups 4 inside the conical cylinder 1 and at both ends of the conical cylinder 1 are used to perform a surrounding extrusion on the plush fabric 19 to remove the water in the plush fabric 19. After the plush fabric 19 leaves from the small-diameter end 3, it is spread out and enters between the drying table 8 and the drying box 9 in a flat state. The lower heating conveyor belt 10 and the upper heating conveyor belt 11 are used to heat the plush fabric 19, and the negative pressure formed by the negative pressure cavity 12 is used to suck away the hot air formed by heating, so as to realize the drying and shaping of the plush fabric 19. When squeezing water, the plush fabric 19 adopts a surrounding extrusion to remove the water after dyeing treatment. While draining water, the water can fully penetrate into the inside of the plush fabric 19, and the dyeing agents, treatment agents, etc. in the water fully enter into the inside of the plush fabric 19, improving the dyeing effect and the color fixing effect. At the same time, it will not damage the fluff on the plush fabric 19 and will not break the fluff. After most of the water is squeezed away, the plush fabric 19 is then subjected to heating and drying treatment.
