[0025] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings.

[0027] To facilitate the understanding of the brushing machine provided by the embodiment of the present application, its application scenario will be described first. The brushing machine provided by the embodiment of the present application is used for brushing the fabric, but there are still problems such as easy pilling and easy hair loss in the existing brushing machine after brushing the fabric. For this reason, the embodiment of the present application provides a brushing mechanism to improve the brushing effect on the fabric. The following will be described in detail with specific drawings and embodiments.

[0028] For the convenience of understanding, two surfaces of the fabric are defined first. The first surface and the second surface of the fabric are two opposite surfaces, and both the first surface and the second surface have plush. In the drawings of the embodiment of the present application, the "+" is used to represent the first surface of the fabric, and the "-" is used to represent the second surface of the fabric.

[0029] Reference Figure 1 As shown Figure 1 FIG. shows a schematic structural diagram of a napping machine provided by an embodiment of the present application. The napping machine provided by the embodiment of the present application includes two trimming devices and two napping devices. For convenience of description, according to the conveying direction of the fabric 100, the trimming devices are respectively named the first trimming device 20 and the second trimming device 40, and the two napping devices are named the first napping device 30 and the second napping device 50. Among them, the trimming device is used to trim the plush on the surface of the fabric 100, and the napping device is used to nap the trimmed plush. Specifically, the first trimming device 20 is used to trim the first surface of the fabric 100, and the first napping device 30 is used to nap the first surface of the fabric 100; the second trimming device 40 is used to trim the second surface of the fabric 100, and the second napping device 50 is used to trim the second surface of the fabric 100. The following will describe each component of the napping machine in detail with reference to specific drawings.

[0030] Continue to refer to Figure 1 , the napping machine provided by the embodiment of the present application further includes a feeding roller group 10, and the feeding roller group 10 is used to convey the fabric 100 into the first napping device 30 and cooperate with the first napping device 30 to tension the fabric 100. Among them, along the conveying direction of the fabric 100 (such as Figure 1 the direction indicated by the straight arrow in), the feeding roller group 10 is located upstream of the first napping device 30, and the first trimming device 20 is located between the feeding roller and the first napping device 30, so as to trim the fabric 100 through the first trimming device 20 before the fabric 100 is fed into the first napping device 30.

[0031] The feeding roller group 10 may include multiple feeding rollers. Exemplarily, in Figure 1 the feeding roller group 10 includes three feeding rollers, and the fabric 100 passes between the three feeding rollers to support and convey the fabric 100. When the fabric 100 enters the feeding roller, the feeding angle γ of the fabric 100 may be between 30° and 45°, so that after the fabric 100 enters the first napping device 30, the fabric 100 between the feeding roller group 10 and the first napping device 30 is tightened and tension is applied. Of course, in addition to the above example of the feeding angle, other feeding angles can also be selected according to needs.

[0032] Continue to refer to Figure 1 , the first trimming device 20 is used to trim the plush on the first surface of the fabric 100 conveyed by the feeding roller group 10. When the first trimming device 20 is arranged between the feeding roller group 10 and the first napping device 30, the first trimming device 20 presses against the first surface of the fabric 100. Combining Figure 1 it can be seen that the feeding roller group 10, the first trimming device 20 and the first napping device 30 are in the height direction (withFigure 1 There is a positional difference in the placement direction (the reference direction), so when the first trimming device 20 presses against the fabric 100, the stress of the first trimming device 20 on the fabric 100 is approximately 10 N, ensuring that the suede on the fabric is evenly exposed and successfully shaved off, so as to unify the height of the fluff on the fabric surface, thereby trimming the fluff of different lengths into fluff of a unified length, which is convenient for the subsequent first napping device 30 to perform napping.

[0033] Refer to together Figure 2 , in a specific embodiment, the first trimming device 20 may include a first electric hair pusher 22 and a first baffle 21. Among them, the first baffle 21 is detachably fixed on the first electric hair pusher 22. During trimming, the first baffle 21 presses against the first surface of the fabric 100 to define the remaining length of the fluff on the fabric 100, that is, to define the distance between the first electric hair pusher 22 and the first surface (the reserved fluff height). Thus, when the first electric hair pusher 22 trims the fluff, the first baffle 21 can be used to make the remaining fluff have a unified height after trimming.

[0034] When the first baffle 21 is detachably connected to the first electric hair pusher 22, the detachable connection can be achieved by snap connection or by a threaded connection member (bolt or screw). In addition, when different fluff heights need to be reserved, different first baffles 21 can be replaced to cooperate with the first electric hair pusher 22.

[0035] In an alternative solution, to facilitate the cleaning of the fluff debris trimmed by the first electric hair pusher 22, the first trimming device 20 provided in the embodiment of the present application may further include a first air extraction device 23 for adsorbing the fluff shaved off by the first electric hair pusher 22. The first air extraction device 23 can be an air suction fan or an air suction pipe driven by an air pump. The suction port of the first air extraction device 23 faces the hair-trimming end of the first electric hair pusher 22, so that the fluff debris trimmed by the first electric hair pusher 22 can be adsorbed away by the first air extraction device 23, reducing the risk of fluff debris sticking to the fabric 100, and further reducing the risk of fluff debris entering the first napping device 30 and contaminating the internal components of the first napping device 30.

[0036] Exemplarily, the initial height value of the blade of the first electric hair pusher 22 can be set at a position 0.12 mm away from the first baffle 21, so as to unify the length of the fluff of the fabric 100. At the same time, a first air extraction device 23 is provided to prevent the cut fluff debris from contaminating the fabric 100 and various rollers in the subsequent first napping device 30, and reduce the situation that the fluff contaminates the rollers during the processing, causing defects such as streaks and wrinkles and affecting the fabric surface effect.

[0037] Of course, in addition to the structure of the first trimming device 20 in the above example, other structures can also be adopted. For example, the first trimming device 20 may further include an electric shaver, and a storage bin is provided to accommodate the plush debris trimmed by the shaver, or a suction device is used to adsorb the trimmed plush debris.

[0038] Continuing to refer to Figure 1 As shown, the trimmed fabric 100 enters the first napping device 30 for napping. The first napping device 30 includes a tension roller and a napping roller. For the convenience of description, the tension roller is named the first tension roller 31, and the napping roller is named the first napping roller 32. Among them, the number of the first tension rollers 31 is multiple, and is used to tension the first surface of the fabric 100 on each first napping roller 32, so that when the fabric 100 contacts the first napping roller 32, the napping effect can be achieved through friction. In the embodiment of the present application, the number of the first napping rollers 32 is at least two, such as two, three or other different numbers, so as to nap the first surface of the fabric 100 sequentially through different first napping rollers 32, thereby improving the napping effect.

[0039] Exemplarily, as Figure 1 shown, the number of the first tension rollers 31 is three, and the number of the first napping rollers 32 is two. Among them, the two first napping rollers 32 and the three first tension rollers 31 are arranged alternately, and each first napping roller 32 is located between two first tension rollers 31 to ensure that the two first tension rollers 31 can provide sufficient tension to make the first surface of the fabric 100 friction with the first napping roller 32. In addition, the rotation of the first tension roller 31 is also used to drive the fabric 100 to move in the first napping device 30. Specifically, the three first tension rollers 31 are respectively the first tension roller A, the first tension roller B and the first tension roller C (in Figure 1 the three first tension rollers 31 are exemplified by A, B, C respectively), and the two first napping rollers 32 are respectively the first napping roller A and the first napping roller B (in Figure 1 the two first napping rollers 32 are exemplified by A, B respectively). Among them, the first napping roller A is located between the first tension roller A and the first tension roller B, and the first napping roller B is located between the first tension roller B and the first tension roller C.

[0040] To ensure that the fabric 100 is in tight contact with the first tension roller A and the first tension roller B, so as to achieve the abrasion of the plush. When specifically arranging the first tension roller A, the first tension roller B and the first tension roller C, the rotational speeds of the three first tension rollers 31 meet the following conditions: the rotational speed of the first tension roller A is less than the rotational speed of the first tension roller B which is less than the rotational speed of the first tension roller C. Exemplarily, the rotational speed of the first tension roller A is 700 r / min, the rotational speed of the first tension roller B is 800 r / min, and the rotational speed of the first tension roller C is 900 r / min. To ensure that when the three first tension rollers 31 rotate, the first surface of the fabric 100 can be tensioned on the first raising roller A and the first raising roller B respectively, so as to ensure the raising effect. In addition, the first tension roller A can also cooperate with the feeding roller outside the first raising device 30 to provide the tension force required for the cooperation between the fabric 100 and the first trimming device 20.

[0041] In an alternative embodiment, the arrangement of the plurality of first tension rollers 31 satisfies that the contact angle between any first raising roller 32 and the first surface of the fabric 100 is between 200° and 240°. Exemplarily, the contact angle can be different angles such as 200°, 210°, 220°, 240°, etc. As Figure 1 shown in the figure, the arrangement positions of the first tension roller A, the first tension roller B and the first tension roller C ensure that the contact angle α between the first surface of the woolen material and any one of the first raising roller A and the first raising roller B is between 200° and 240°, so as to ensure that the first surface of the fabric 100 has sufficient contact area with the first raising roller A and the first raising roller B, while increasing the contact area between the fabric 100 and the raising roller, protecting the strength of the fabric 100. It should be understood that other angles that can satisfy the contact area with the first fabric 100 can also be applied to the embodiments of the present application. For example, when three or four first raising rollers 32 are used, the contact angle between each first raising roller 32 and the fabric 100 can be appropriately reduced.

[0042] In an alternative embodiment, at least two first raising rollers 32 are arranged in a staggered manner. As Figure 1 shown in the figure, the two first raising rollers 32 are arranged in a staggered manner along the height direction of the first raising device 30. Similarly, the three first tension rollers 31 are also arranged in a staggered manner to ensure cooperation with the corresponding first raising rollers 32 to provide sufficient tension. By adopting the above-mentioned staggering method, the height space of the first raising device 30 can be fully utilized, and the two first raising rollers 32 and the three first tension rollers 31 can be arranged more reasonably. At the same time, the contact angle between the fabric 100 and the first raising rollers 32 and the tension requirements are also met by the minimum number of first tension rollers 31, reducing the number of first tension rollers 31. Of course, when the space of the first raising device 30 is sufficient, at least two first raising rollers 32 can also be arranged side by side.

[0043] Refer to together Figure 3and Figure 4 As shown in Figure 4 , when brushing the first surface of the fabric 100, each first brushing roller 32 includes a plurality of steel needle rollers 321 fixedly arranged, and the plurality of steel needle rollers 321 are arranged in a ring. As Figure 1 and Figure 3 shown, the diameters of the plurality of steel needle rollers 321 in the first brushing roller 32 are the same and surround to form a ring. And a plurality of bent steel needles 322 are arranged on each steel needle roller 321, and the bending directions of the steel needles 322 on any adjacent steel needle rollers 321 are opposite. Exemplarily, continuing to refer to Figure 4 , the steel needles 322 on each steel needle roller 321 are in an inverted L-shaped bending structure. Among them, the vertical portion 322a of the steel needle 322 is fixedly connected to the cylindrical roller body of the steel needle roller 321, and the horizontal portion 322b forms an angle of 100° - 150° with the vertical portion 322a and is used to contact the plush of the fabric 100 and brush the plush. In addition, among any two adjacent steel needle rollers 321, the bending directions of the steel needles 322 on them are opposite, that is, the horizontal portions 322b of the steel needles 322 on any two adjacent steel needle rollers 321 are arranged oppositely or back to back. When brushing the fabric 100, the steel needles 322 on the steel needle roller 321 can brush the plush on the fabric 100. The end of the horizontal portion 322b of the steel needles 322 on some steel needle rollers 321 away from the vertical portion 322a contacts the plush, while the end of the horizontal portion 322b of the steel needles 322 on some steel needle rollers 321 close to the vertical portion 322a contacts the plush, which can reduce the large damage to the fabric 100 caused by a single brushing direction and the easy generation of holes, and through this brushing method, a more uniform brushing effect can also be achieved to protect the strength of the fabric 100.

[0044] Of course, in addition to the above-exemplified solution for the structure of the first brushing roller 32, other structures that can achieve brushing can also be adopted. For example, the first brushing roller 32 adopts a cylindrical roller body, and bent steel needles 322 or arc-shaped steel needles 322 are directly arranged on its roller body. When adopting arc-shaped steel needles 322, along the circumferential direction of the first brushing roller 32, the arc bending directions of adjacent steel needles 322 are opposite.

[0045] Continuing to refer to Figure 1 shown in Figure 1 , the first brushing device 30 provided in the embodiment of the present application further includes a first idler roller group 33, and the first idler roller group 33 is used to convey the fabric 100 brushed by the plurality of first brushing rollers 32 out of the first brushing device 30. As Figure 1As shown in [reference], the number of rollers in the first roller group 33 is three, and the three rollers are used to clamp and support the fabric 100 to convey it out of the first napping device 30. It should be understood that other roller groups can also be provided in the first napping device 30 according to requirements to support the transmission of the fabric 100 in the first napping roller 32, and the positions where they are provided can be set according to requirements, which are not specifically limited in the embodiments of the present application.

[0046] Continue to refer to Figure 1 As shown in [reference], the second trimming device 40 provided in the embodiments of the present application is used to trim the plush on the second surface of the fabric 100. Among them, along the conveying direction of the fabric 100, the second trimming device 40 is located upstream of the second napping device 50 to trim the plush on the second surface of the fabric 100 through the second trimming device 40 before the fabric 100 enters the second napping device 50.

[0047] Specifically, the second trimming device 40 includes a second electric hair pusher and a second baffle detachably fixed to the second electric hair pusher; among them, the second baffle is used to press against the second surface of the fabric 100 and is used to limit the amount of hair shaved by the second electric hair pusher; the second trimming device 40 also includes a second air extraction device for adsorbing the plush shaved by the second electric hair pusher. Among them, the structures and functions of the second baffle, the second electric hair pusher, and the second air extraction device in the second trimming device 40 are similar to the structures and functions of the first baffle 21, the first electric hair pusher 22, and the first air extraction device 23 in the first trimming device 20. Therefore, the second trimming device 40 can refer to the description of the first trimming device 20 in the above text and will not be elaborated here.

[0048] Continue to refer to Figure 1 As shown in [reference], the second napping device 50 includes a tension roller and a napping roller. For the convenience of description, the tension roller is named the second tension roller 51, and the napping roller is named the second napping roller 52. Among them, the number of the second tension rollers 51 is multiple and is used to tension the second surface of the fabric 100 on each second napping roller 52 so that when the fabric 100 contacts the second napping roller 52, the napping effect can be achieved through friction. In the embodiments of the present application, the number of the second napping rollers 52 is at least two, such as two, three, etc. different numbers, so as to nap the second surface of the fabric 100 in sequence through different second napping rollers 52, thereby improving the napping effect.

[0049] Exemplarily, the three second tension rollers 51 are respectively the second tension roller D, the second tension roller E, and the second tension roller F (the three second tension rollers 51 are respectively exemplified by D, E, and F in Figure 1 [reference]), and the two second napping rollers 52 are respectively the second napping roller C and the second napping roller D (in Figure 1Two second sanding rollers 52 are respectively exemplified by C and D. Among them, the second sanding roller C is located between the second tension roller D and the second tension roller E, and the second sanding roller D is located between the second tension roller E and the second tension roller F. To ensure that the fabric 100 is in tight contact with the second tension roller D and the second tension roller E, so as to realize the abrasive treatment of the plush.

[0050] When specifically arranging the second tension roller D, the second tension roller E and the second tension roller F, the rotation speeds of the three second tension rollers 51 satisfy the following conditions: the rotation speed of the second tension roller D is less than the rotation speed of the second tension roller E which is less than the rotation speed of the second tension roller F. Exemplarily, the rotation speed of the second tension roller D is 1000 r / min, the rotation speed of the second tension roller E is 1100 r / min, and the rotation speed of the second tension roller F is 1200 r / min. To ensure that when the three second tension rollers 51 rotate, the second surface of the fabric 100 can be respectively tensioned on the second sanding roller C and the second sanding roller D, so as to ensure the sanding effect. In addition, the second tension roller D can also cooperate with the feeding roller outside the second sanding device 50 to provide the tension required for the cooperation between the fabric 100 and the second trimming device 40. At the same time, the rotation speed of the second tension roller D is greater than the rotation speed of the first tension roller C to ensure that the fabric 100 can also be kept tensioned synchronously when being transmitted between the first sanding device 30 and the second sanding device 50, so as to provide the tension required for the cooperation between the second surface of the fabric 100 and the second trimming device 40.

[0051] To ensure the sanding effect, when arranging multiple second tension rollers 51, the arrangement mode of the multiple second tension rollers 51 satisfies that the contact angle β between any second sanding roller 52 and the second surface of the fabric 100 is between 200° and 240°. Exemplarily, the contact angle β can be different angles such as 200°, 210°, 220°, 240°, etc. Its function is the same as that of the arrangement of the first tension roller 31 and will not be elaborated here.

[0052] In a specific implementation, at least two second sanding rollers 52 are arranged in a staggered manner, such as Figure 1 As shown in, the two second sanding rollers 52 are arranged in a staggered manner along the height direction of the second sanding device 50. Similarly, the three second tension rollers 51 are also arranged in a staggered manner to ensure cooperation with the corresponding second sanding rollers 52 and provide sufficient tension. Its function is the same as that of the cooperation between the first tension roller 31 and the first sanding roller 32 and will not be elaborated here.

[0053] The structure and function of the second sanding roller 52 provided in the embodiment of the present application are the same as those of the first sanding roller 32. The structure and function of the second sanding roller 52 can refer to the structure and function of the first sanding roller 32 and will not be elaborated here.

[0054] Continue to refer to Figure 1As shown in the figure, the second napping device 50 provided in the embodiments of the present application further includes a second idler roller group 53, and the second idler roller group 53 is used to convey the fabric 100 after being napped by the plurality of second napping rollers 52 out of the second napping device 50. As Figure 1 As shown in the figure, the number of idler rollers in the second idler roller group 53 is three, and the three idler rollers are used to clamp and support the fabric 100 to convey it out of the second napping device 50. It should be understood that other idler roller groups can also be provided in the second napping device 50 according to needs to support the transmission of the fabric 100 in the second napping rollers 52, and the positions where they are set can be determined according to needs, and no specific limitation is made in the embodiments of the present application.

[0055] As an optional solution, the napping machine provided in the embodiments of the present application may further include a third idler roller group 60 located between the first napping device 30 and the second napping device 50; the third idler roller group 60 is used to convey the fabric 100 into the second napping device 50 and make the first surface of the fabric 100 contact the second tension roller 51. Among them, the third idler roller group 60 may also include a plurality of idler rollers, and when conveying the fabric 100, the first surface of the fabric 100 is made to contact the second tension roller D, so that the second surface of the fabric 100 can contact the second napping roller C for napping.

[0056] It can be seen from the above description that in the napping machine provided in the embodiments of the present application, before napping any surface of the fabric 100, the fabric 100 is trimmed first, so as to reduce the pollution of the napping roller during napping due to too long fluff. In addition, by napping the first surface and the second surface of the fabric 100 with the first napping device 30 and the second napping device 50 respectively, the effect of uniform napping on both sides of the fabric 100 can be achieved, improving the napping effect and the structural strength of the fabric 100, so that the fabric 100 can be thinner, more delicate, and have a softer hand feeling.

[0057] When applying the napping machine provided in the embodiments of the present application, different numbers of napping machines can be selected for cooperation according to different fabrics 100. Exemplarily, when the fabric 100 is a regenerated cellulose fiber / cotton / acrylic and other blended materials, 1-2 sets of napping machines can be connected in series according to the thickness of the fabric 100. When the fabric 100 is a polyester fiber / nylon and other blended materials, 1-3 sets of napping machines can be connected in series according to the thickness of the fabric 100. Of course, other numbers of napping machines can also be used for cooperation according to needs.
