Description

Technical Field

[0001] This utility model belongs to the field of textile fabric processing, and in particular relates to a textile fabric brushing device. Background Technology

[0002] Napping is a common processing technique in textile fabric manufacturing. Napping rollers create a short, fluffy layer on the fabric surface, improving its softness and appearance. However, traditional napping machines generate a large amount of lint during operation. This lint adheres to the napping rollers and may be pressed back onto the fabric, causing defects such as white spots and streaks. Lint floating in the air may also get caught in the drive motor, causing malfunctions.

[0003] Existing technologies typically use simple industrial vacuum cleaners to remove lint, but the cleaning effect is not good. After long-term operation, lint tends to accumulate at the bottom of the chamber, requiring regular shutdowns for cleaning, which affects production efficiency. Utility Model Content

The device includes a housing with a fabric inlet and a fabric outlet. At least one abrasive roller is housed within the housing. Guide rollers are positioned in front of and behind the abrasive roller. A cleaning roller is positioned below each abrasive roller, capable of contacting its underside. The shaft of the abrasive roller extends out of the housing and connects to the abrasive motor, while the shaft of the cleaning roller extends out of the housing and connects to... The cleaning motor is connected, and a collection cabinet with an open top is set below the cleaning roller. The cleaning roller is set at the upper end of the collection cabinet. There is a cabinet door on one side of the box, and a hair collection box connected to the fan is set on the outside of the other side of the box. The collection cabinet is connected to the hair collection box through a collection cabinet connecting pipe. There is a cabinet door on the lower side of the collection cabinet. There is an upward-opening suction plate between the rear of the collection cabinet and the box wall. There is an opening at the bottom of the suction plate. The opening of the suction plate is connected to the hair collection box through a suction plate connecting pipe. There is an air inlet on the box.

[0005] Preferably, the upper port of the collection cabinet is funnel-shaped, and the lower part of the cleaning roller is located inside the upper port of the collection cabinet.

[0006] Preferably, the height of the upper port edge of the collection cabinet is lower than the lower horizontal section of the guide roller, and the distance between the upper port edge of the collection cabinet and the lower horizontal section of the guide roller is less than or equal to 12 cm.

Detailed Implementation

[0012] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0013] In this invention, "front" refers to the direction in which the textile fabric is conveyed, and "rear" refers to the direction in which the textile fabric is conveyed. It should be noted that the terms "front," "rear," "upper," and "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the purpose of simplifying the description of this invention and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0014] like Figures 1 to 4 As shown, the textile fabric napping device disclosed in this utility model includes a housing 1, with a fabric inlet 2 at the front and a fabric outlet 3 at the rear. Two napping rollers 4 are installed inside the housing 1, connected by bearings between the left and right inner walls of the housing 1. The rotating shaft of the napping roller 4 is connected to the output shaft of the napping motor 7. The napping roller 4 is an existing product, including a metal shaft with brush bristles. The napping motor 7 drives the napping roller 4 to rotate, and the brush bristles of the napping roller 4 rub against the fabric to form a short nap layer. The housing 1 prevents lint from blowing outwards and affecting the surrounding environment and other equipment. At least one napping roller 4 is installed inside the housing 1; however, two or more napping rollers 4 can be installed along the front-to-back direction inside the housing 1, depending on the napping process requirements.

[0015] A guide roller 5 is provided at the front and rear of the abrasive roller 4. The guide rollers 5 are connected by bearings and mounted between the left and right inner walls of the housing 1. The height and diameter of each guide roller 5 are the same. The textile fabric passes sequentially under the front guide roller 5, above the abrasive roller 4, and below the rear guide roller 5, so that the fabric is transported smoothly and the abrasive roller 4 can fully contact the fabric to achieve abrasion.

[0016] Below each abrasive roller 4 is a cleaning roller 6 that contacts the bottom of the abrasive roller 4. The bottom refers to the lowest point of the cylindrical surface of the abrasive roller 4. The cleaning roller 6 is mounted between the left and right inner walls of the housing 1 via bearings, and the shaft of the cleaning roller 6 extends out of the housing 1 and is connected to the cleaning motor 8. The cleaning roller 6 has a ring of outwardly extending cleaning structure on its roller wall, which can be a scraper or a nylon brush, etc. When the cleaning roller 6 rotates with the abrasive roller 4, the cleaning structure of the cleaning roller 6 sweeps across the brush bristles on the abrasive roller 4, thereby scraping the lint off the cleaning roller 6.

[0017] A collection cabinet 9 is installed below the cleaning roller 6. The collection cabinet 9 is a metal cabinet with an open top, and the upper port of the collection cabinet 9 is trumpet-shaped, meaning that the diameter of the upper port gradually increases from bottom to top. The cleaning roller 6 is located at the upper port of the collection cabinet 9, and the lower part of the cleaning roller 6 is located inside the upper port of the collection cabinet 9. The height of the edge of the upper port of the collection cabinet 9 is lower than the lower horizontal sectional surface of the guide roller 5, and the distance between the height of the edge of the upper port of the collection cabinet 9 and the lower horizontal sectional surface of the guide roller 5 is less than or equal to 12 cm.

[0018] The "lower horizontal tangent of guide roller 5" refers to the tangent plane at the lowest point of the cylindrical surface of guide roller 5, i.e. Figure 2 The plane where the fabric horizontal conveying section is located is shown. The upper edge of the collection cabinet 9 is lower than the height of the fabric horizontal conveying surface, so it does not affect the fabric operation; moreover, it reduces the distance between the upper edge of the collection cabinet 9 and the horizontal plane cut by the guide roller 5, making them as close as possible, so as to more thoroughly absorb the lint below the abrasive roller 4. The upper end of the collection cabinet 9 adopts a trumpet-shaped upper port, which can expand the air suction range. The lower part of the cleaning roller 6 is located inside the upper port of the collection cabinet 9, which can make the scraped lint more reliably sucked into the collection cabinet 9.

[0019] like Figures 2 to 6 As shown, a cabinet door 10 is provided on the lower side of the collection cabinet 9, and a cabinet door 11 is provided on one side of the box body 1. A hair collection box 12 is provided on the other side of the box body 1, and the collection cabinet 9 is connected to the hair collection box 12 through a collection cabinet connecting pipe 13. A fan 14 is provided outside the hair collection box 12, and the exhaust pipe of the fan 14 is connected to the side wall of the hair collection box 12. A hair collection box door 18 is also provided on the hair collection box 12. The fan 14 can be an industrial dust removal fan, and its exhaust pipe has a built-in filter at the connection between it and the hair collection box 12. When the fan 14 is turned on, it draws air outward, creating a negative pressure inside the hair collection box 12. Through the collection cabinet connecting pipe 13, a negative pressure is created in the upper port area of ​​the collection cabinet 9. The collection cabinet 9 forms a downward suction airflow on the cleaning roller 6, drawing the hair into the collection cabinet 9 and drawing most of the hair into the hair collection box 12 through the collection cabinet connecting pipe 13. A very small amount of hair will fall to the bottom of the collection cabinet 9. After a certain amount of lint is collected in the lint collection box 12, staff can periodically open the lint collection box door 18 to clean the lint inside. Since the lint collection box 12 is independent of the box body 1, it can be safely cleaned without stopping the lint-removing device. The lint at the bottom of the collection cabinet 9 accumulates very slowly, and staff can open the cabinet door 10 to clean it during the periodic maintenance of the lint-removing device, without having to stop the machine specifically for cleaning.

[0020] A lint-absorbing tray 15 with an upward opening is installed between the rear of the collection cabinet 9 and the inner wall of the box body 1. The bottom of the lint-absorbing tray 15 has an opening, which connects to the lint collection box 12 via a lint-absorbing tray connecting pipe 16. A lint-absorbing tray 15 connected to the lint collection box 12 is also installed between the two abrasive rollers 1, located at the bottom of the box body 1. The lint-absorbing tray 15 has a disc-shaped structure. When the fan 14 is turned on to extract air, a negative pressure is formed at the opening of the lint-absorbing tray 15, which can suck and collect the lint in the internal space of the box body after the fabric has been abraded. The lint-absorbing tray 15's location at the bottom of the box body 1 increases the absorption range of airborne lint, preventing lint from falling onto the bottom of the box body 1.

[0021] The housing 1 has an air inlet 17, which is a long and narrow opening located on the upper left and right sides of the housing 1. After the fan 14 is turned on to extract air, a negative pressure is formed inside the housing 1, and outside air will enter the housing 1 through the air inlet 17 to form a continuous gas circulation.

[0022] Both the fabric inlet 2 and the fabric outlet 3 are inclined, with the inside lower than the outside. "Inner lower than outer higher" means that the height of the side of the fabric inlet 2 and the fabric outlet 3 closest to the inside of the housing 1 is lower than the height of the side closest to the outside of the housing 1. A guide roller 5 is installed at the rear of the fabric inlet 2 and the front of the fabric outlet 3 inside the housing 1. The inner-lower, outer-higher opening design prevents lint from flying out of the opening. The guide roller 5 at the fabric inlet 2 guides the inclined fabric to a horizontal conveying position, and the guide roller 5 at the fabric outlet 3 guides the horizontal fabric to an upward angle for output, ensuring smooth entry and exit of the fabric from the housing 1.

[0023] Finally, it should be noted that the above embodiments are merely specific implementations of this utility model, used to illustrate the technical solution of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto. Those skilled in the art should understand that any person skilled in the art can modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this utility model; and these modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be covered within the protection scope of this utility model.
