Description

Technical Field

[0001] The utility model relates to the technical field of napping fabrics, in particular to a napping device for sofa fabrics. Background Art

[0002] The napping treatment on the surface of the sofa fabric can achieve a special aesthetic and comfortable effect, which is loved by consumers. The napping operation is usually done manually, that is, after the functional fabric is flattened, a metal brush is used to brush it back and forth on a local position to pull the fiber ends of the fabric out of the fabric, so that the surface of the sofa fabric is evenly covered with a layer of fluff.

[0003] During the process of brushing the fabric, the fabric is conveyed and then operated with a metal brush. The effect of extrusion and friction on different fabrics is different. Some fabrics require a larger extrusion force to achieve a layer of fluff on the fabric. Different fabrics have different elastic coefficients. During the operation, the excessive extrusion force of the metal brush can easily cause the fabric to deform and be difficult to recover. Therefore, local improvements are proposed here.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-6 The utility model provides a technical solution: a napping device for sofa fabrics, comprising a shell 1, wherein two groups of U-shaped frames 4 that can slide up and down are arranged in the shell 1, and two processing rollers 5 are rotatably installed on the inner side of each group of U-shaped frames 4, and the two processing rollers 5 are arranged in an upper and lower distribution. The outer wall of the processing roller 5 has a metal end 56 extending outward, and the end of the metal end 56 is roughly arranged. During the transmission of the fabric, it is squeezed with the outer wall of the processing roller 5 and the metal end 56, and the fabric end face is subjected to force through the squeezing of the metal end 56.

[0025] Two transmission shafts 2 arranged opposite to each other are rotatably mounted on the inner side of the shell 1 near the upper end. The transmission shafts 2 are used to transmit the fabric and to change the direction of fabric transmission.

[0026] The outer walls of both sides of the housing 1 are provided with longitudinal slide grooves 11, and a support shaft 31 extending downward is fixed inside the longitudinal slide grooves 11. An I-shaped slider 3 is fixed at the lower end of the support shaft 31. The I-shaped slider 3 is clamped in the longitudinal slide grooves 11, and the I-shaped slider 3 is used to move up and down;

[0027] The support shaft 31 can be telescopically arranged and has a reset spring inside. Under a sudden external pulling force, a force is exerted on the fabric, and the fabric will be suddenly tightened, affecting the quality of the fabric. Therefore, the I-shaped slider 3 can squeeze the support shaft 31 upward to achieve upward movement, thereby avoiding as much as possible the deformation of the fabric that is difficult to recover.

[0028] The U-shaped frame 4 is fixed on the inner side of the I-shaped slider 3 . The interior of the processing roller 5 is hollow. An outer hole 54 extending inward is formed on the outer wall of the processing roller 5 . The metal end 56 is inserted into the inner part of the outer hole 54 .

[0029] Both ends of the processing roller 5 extend through the U-shaped frame 4, one end of the processing roller 5 is connected to the inside thereof, and an inner roller 51 is inserted into the processing roller 5, the outer wall of the inner roller 51 is in a continuously extending arc shape, and the edge of the arc shape protrudes outward to contact the metal end 56, and the inner roller 51 is rotated, and different positions of the inner roller 51 have different effects on squeezing the metal end 56;

[0030] The end of the inner roller 51 extends from one end of the processing roller 5, and the extended end is a connecting shaft 52 with a thread. The connecting shaft 52 is threadedly connected with a matching nut 53 for tightening. The matching nut 53 is rotated to squeeze the inner roller 51 and the processing roller 5. The matching nut 53 is rotated to achieve force on the inner roller 51, and the position between the inner roller 51 and the processing roller 5 is limited relative to the inner roller 5, so as to avoid the rotation of the inner roller 51 to produce movement.

[0031] The outer hole 54 on the outer wall of the processing roller 5 is arranged in a rectangular shape, and a vertical limiting rod body 55 is fixed inside the outer hole 54. The metal end 56 is arranged in two halves, and a through hole 561 is provided on the two halves of the metal end 56. A limiting opening 562 is provided on the contact surface of the two halves of the metal end 56. The limiting opening 562 is used to clamp the limiting rod body 55. The outer hole 54 is rectangular, and the metal end 56 can be divided into two halves, so that the metal end 56 can be separated and taken out, and the limiting rod body 55 limits the metal end 56 and can slide in the inner and outer directions.

[0032] When in use, the fabric is transmitted from the transmission shaft 2, and extends downward to be inserted between the two processing rollers 5, so that the processing rollers 5 process both sides of the fabric, and then it is inserted between the two processing rollers 5 on the other side, and processed again, and then it extends upward from another transmission shaft 2 to achieve multiple processing and molding of both sides together. Since the fabric receives the same pulling force, the two sides of the fabric are squeezed to the same degree by the metal end 56, so the same degree of roughening is achieved on both sides of the fabric;

[0033] Secondly, the connecting shaft 52 is rotated to drive the inner roller 51 to rotate. The position of the inner roller 51 changes the squeezing position of the metal end 56 and the inner roller 51, which can drive the metal end 56 to extend out of the outer hole 54, thereby changing the squeezing effect between the metal end 56 and the fabric. The squeezing of the metal end 56 can be achieved on fabrics with different elasticity, ensuring that the fabric has a napping effect.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
